股骨转子间骨折是最常见的髋部骨折,内固定手术为其目前治疗的首选方式。头颈钉位置是评估手术效果和判断治疗预后的重要因素,合适的置钉位置有利于稳定骨折、加速康复以及改善预后。目前头颈钉位置最经典的评估方式为尖顶距（TAD）,但TAD至今仍存在较多争议。近年来提出的轴刀角、尖颈距离比、偏心距（ED）以及标准化TAD（STAD）为临床实践拓展了新视野。文章通过对上述头颈钉位置的评估方法及局限性进行文献综述,旨在为临床手术置钉时提供相应的参考。ED和STAD的提出,为未来人工智能评估头颈钉位置提供了可能。

Femoral intertrochanteric fracture is one of the most common hip fractures, and the internal fixation is the preferred treatment. The position of cephalic fixator is an important factor to evaluate the effect of operation and the prognosis of treatment. Tip-apex-distance（TAD）is the most classical method to evaluate the position of cephalic fixator, but it is still controversial. In recent years, the axis-blade angle,tip-neck distance ratio, eccentric distance（ED）and standardized TAD（STAD）have been proposed,though with limitations, they also provide a new perspective for clinical practice. In this study, we reviewed the literature on the evaluation of the position of cephalic fixator in order to provide the corresponding references and guidance for the clinical operation of internal fixation. Both STAD and ED may be the theoretical possibility of artificial intelligence evaluation of the position of cephalic fixator in the future.

Objective To explore the effect of bile duct ligation induced obstructive cholestasis on rat hepatocytes. Methods Ten Lewis rats were randomly divided into control group and cholestasis group, and the cholestasis was induced by bile duct ligation for 2 weeks. The histopathological changes were compared by H&E and aniline blue staining and the liver function was compared by biochemical analysis. Primary hepatocytes were isolated by modified two-step collagenase perfusion, and the expressions of hepatocyte marker genes, cell proliferation marker genes and cholangiocyte marker genes were detected by RT-qPCR. Results Compared with the control group,the liver of the cholestatic group showed obvious disordered histopathology, deposition of fibrous collagen and impaired liver function. Compared with the control group, the primary hepatocytes in the cholestasis group expressed higher cell proliferation-related genes（Ki67,Foxm1,Pcna and HGF）（P<0. 05）. Primary hepatocytes in the cholestasis group expressed lower levels of hepatocyte marker genes（Alb,Mrp2,Bsep and Catenin1）（P<0. 05）,and higher levels of cholangiocyte marker genes（Ck7,Ck19,Mdr1 and Cftr）（P<0. 05）and higher levels of the hepatic progenitor cell marker genes（Epcam and Sox9）（P<0. 05）. Conclusions Cholestasis induces rat hepatocyte plasticity in the transformation into bile duct properties.

        儿童孤立性直肠溃疡综合征（SRUS）是一种较为罕见的慢性直肠疾病,儿童发病率低且缺乏明确统计学数据。该病主要表现为便血、排黏液便和排便不尽感,临床诊断较为困难,常易误诊为其他疾病。其发病机制尚不明确,可能与排便习惯异常、直肠黏膜异常、血管异常以及遗传易感性等多种因素有关,其中 CHEK2 基因的 p.H371Y 突变可能在发病机制中起关键作用。诊断需综合病史、体格检查以及排粪造影、超声内镜、肠镜检查与组织病理活检等多种辅助检查手段。治疗上目前尚无统一指南,主要包括改善饮食和排便习惯、生物反馈治疗、药物治疗、内镜下治疗和外科手术治疗等,但总体治疗难度较大且复发率较高。本文对儿童 SRUS 的流行病学、发病机制、临床表现、诊断和治疗等方面的研究进展进行综述,旨在提高临床医师对该病的诊疗水平,为未来进一步的研究提供参考依据。

Objective To explore the regulatory mechanism of septic myocardial injury by prohibitin 2（PHB2）. Methods Rat myocardial cell lines（H9C2）were cultured in vitro and divided into control group,LPS group,LPS + PHB2 siRNA（si-PHB2） group. The indicators for detecting oxidative stress include the levels of intracellular malondialdehyde（MDA）and reactive oxygen species（ROS）. The indicators for mitochondrial detection include adenosine triphosphate（ATP）levels,mitochondrial membrane potential,mitochondrial electron microscopy,and semi-quantitative mitochondrial scoring. Western blotting was used to detect the expression of PHB2,PTEN induced putative kinase（PINK1）,Parkin,mitochondrial transcription factor A（TFAM）. Results After LPS stimulation,MDA level and intracellular ROS level increased,ATP level decreased. Compared with LPS group,MDA（6. 21±0. 39 vs 3. 59±0. 33, P<0. 05）level and intracellular ROS level（15 131. 37±88. 72 vs 8 628. 67±71. 95, P<0. 05）in LPS + si-PHB2 group increased significantly,while ATP（3. 46±0. 34 vs 4. 52±0. 25, P<0. 05）and MMP（0. 33±0. 04 vs 0. 55±0. 09, P<0. 05）level further decreased. Compared with the normal group,the structure of mitochondria in LPS group and LPS + si-PHB2 group was damaged in different degree. The semi-quantitative score of mitochondrial damage showed that the damage in LPS + si-PHB2 group was more obvious than that in LPS group（1. 42±0. 10 vs 0. 81±0. 04, P<0. 05）. Western blotting showed that the expression of PHB2,PINK1 and Parkin were up-regulated and the expression of TFAM was down-regulated after LPS treatment,mitohagy-related proteins PINK1（1. 33±0. 06 vs 1. 79±0. 21, P<0. 05）,Parkin（1. 43±0. 08 vs 1. 86±0. 09, P<0. 05）and mitochondrial biogenetic protein TFAM（0. 29±0. 01 vs 0. 74±0. 06, P<0. 05）in LPS+si-PHB2 group were lower than those in LPS group. Conclusions LPS can promote the expression of PHB2 in rat cardiomyocytes. After interfering with PHB2 expression,we found that mitochondrial autophagy and biogenesis are inhibited,and mitochondrial dysfunction,oxidative stress exacerbated,suggesting that the up-regulation of PHB2 expression may restore mitochondrial homeostasis and improve mitochondrial function in septic myocardial injury.

目的 探讨传统术式联合骶主韧带复合体交叉悬吊术与骶棘韧带悬吊术（SSLF）在前盆腔膨出方面的相对疗效与价值。方法 回顾性分析2019年1月—2021年3月安徽医科大学附属六安医院收治的80例重度盆腔器官脱垂（POP）患者临床资料。将接受传统经阴道子宫切除术、阴道前后壁修补术及骶棘韧带悬吊术的40例患者纳入对照组,在上述术式基础上加行骶主韧带复合体交叉悬吊术的40例患者纳入观察组。所有纳入研究的POP患者的盆腔器官脱垂定量评估（POP-Q）评分结果为Ⅱ~Ⅳ度。对比两组患者的围术期指标,包括手术时间、术中出血量、术后病率（定义为术后24 h内连续2次、相隔4 h体温超过38 ℃）、术后留置导尿时间、术后住院时间,以及术中和术后并发症等。此外,术后对患者分别进行了电话随访及门诊复查,随访时间为术后3个月、6个月、1年和2年。生活质量评价采用盆底功能障碍性疾病症状问卷（PFDI-20）和盆底疾病生命质量影响问卷（PFIQ-7）。结果 两组患者手术时间、术中出血量、术后留置导尿时间比较差异均有统计学意义（P<0.05）,观察组术中出血量少于对照组,手术时间短于对照组,尿管留置时间短于对照组;两组患者术后住院时间、术后病率（手术后24 h内连续2次、相隔4 h体温超过38℃）比较差异无统计学意义（P>0.05）。两组间术前PFIQ-7和PFDI-20评分比较差异无统计学意义（P>0.05）;术后2年评分观察组高于对照组（P<0.05）。结论 经阴道子宫切除+阴道前后壁修补+骶棘韧带悬吊术及在上述术式基础上行骶主韧带复合体交叉悬吊术,均为临床治疗重度POP的常用手术方式。后者在治疗重度POP的主、客观治愈率上高于传统修补术式,且复发率更低,疗效更加持久。此外,骶主韧带复合体交叉悬吊术在改善单纯SSLF术后前盆腔膨出方面具有显著优势,为临床上POP的治疗与预后提供了新的思路。

Objective To explore the relative efficacy and value of the combination of traditional surgical methods with cross suspension of the sacro–uterine ligament complex and sacrospinous ligament suspension（SSLF）in preventing the recurrence of anterior pelvic prolapse after surgery. Methods This study retrospectively analyzed the clinical data of 80 patients with severe pelvic organ prolapse in Lu’an Hospital Affiliated to Anhui Medical University from January 2019 to March 2021. In the control group,patients received traditional transvaginal hysterectomy,repair of the anterior and posterior vaginal walls,and sacrospinous ligament suspension, while in the observation group, cross suspension of the sacro–uterine ligament complex was added on the basis of traditional surgical methods. The patients participating in the study were divided into the observation group（40 cases）and the control group（40 cases）according to different surgical methods. All patients with pelvic organ prolapse（POP）included in this study had POP–Q scores of grade II to IV. We compared the perioperative indicators of the two groups,including operation time, intraoperative blood loss, postoperative morbidity （defined as a body temperature exceeding 38°C for two consecutive times within 24 hours after surgery,separated by 4 hours）, postoperative indwelling catheterization time, postoperative hospital stay, and intraoperative and postoperative complications. In addition, patients were followed up by telephone and outpatient reexamination after surgery at 3 months, 6 months, 1 year, and 2 years. The quality of life was evaluated using the Pelvic Floor Dysfunction Symptom Questionnaire （PFDI–20） and the Pelvic Floor Disease Quality of Life Impact Questionnaire （PFIQ–7）. Results Comparing the operation time, intraoperative blood loss, and postoperative indwelling catheterization time of the two groups, there were statistically significant differences, P<0. 05. The intraoperative blood loss in the observation group was less than that in the control group, the operation time was shorter than that in the control group, and the indwelling catheter time was shorter than that in the control group. There was no statistically significant difference in postoperative hospital stay and postoperative morbidity（within 24 hours after surgery, two consecutive times with a body temperature exceeding 38°C separated by 4 hours）between the two groups, P>0. 05. There was no statistically significant difference in preoperative PFIQ–7 and PFDI–20 scores between the two groups（P>0. 05）, however, the scores of the observation group were higher than those of the control group 2 years after surgery, and the difference was statistically significant（P<0. 05）. Conclusions Traditional transvaginal hysterectomy + repair of the anterior and posterior vaginal walls + sacrospinous ligament suspension and cross suspension of the sacro–uterine ligament complex based on traditional surgical methods are both common surgical methods for the clinical treatment of severe pelvic organ prolapse. Studies have shown that the latter has a higher subjective and objective cure rate and a lower recurrence rate in the treatment of severe pelvic organ prolapse, with a more durable therapeutic effect. In addition,cross suspension of the sacro–uterine ligament complex has significant advantages in improving anterior pelvic prolapse after simple SSLF, providing new ideas for the treatment and prognosis of pelvic organ prolapse in clinical practice.

Objective To explore the current situation and influencing factors of bladder spasms in patients after kidney transplantation. Methods Selecting 80 kidney transplant patients admitted to the First Affiliated Hospital of Guangzhou Medical University from December 2022 to April 2024 as the research subjects, the occurrence of postoperative bladder spasm was recorded. Fifteen patients who experienced bladder spasm after surgery were included in the bladder spasm group, and the remaining 65 patients were included in the non bladder spasm group. The general demographic data,preoperative clinical data, intraoperative and postoperative conditions between two groups were compared. Incorporating bladder spasm as the dependent variable into the Logistics regression model to analyze the influencing factors of bladder spasm after kidney transplantation. Results A total of 15 out of 80 kidney transplant patients experienced bladder spasms after surgery, accounting for 18. 76%. By comparing general demographic data between the bladder spasm group and the non bladder spasm group, it was found that there were no significant differences in gender, age, Body Mass Index, education level, payment methods, and household income（P>0. 05）. There was no significant differences in primary disease, combined basic disease, and dialysis method between the two groups（P>0. 05）,while there were significant differences in preoperative dialysis time and preoperative anemia between the two groups（P<0. 05）. Surgical time, intraoperative blood loss,postoperative urinary retention, postoperative visual analog scale score, C reactive protein, tumor necrosis factor-α, interleukin-6, alkaline phosphatase, transaminase, creatinine, urea nitrogen, cystatin C were not different between the two groups（P>0. 05）. The difference in the mean urine volume after seven days and urinary catheter material were significant（P<0. 05）. According to the results of the Logistic regression analysis,preoperative dialysis duration（95%CI：1. 327-9. 846,OR：3. 614, P=0. 012）, preoperative anemia（95%CI：0. 995-1. 000,OR：0. 997, P=0. 045）, catheter material（95%CI：1. 498-3 199. 687,OR：69. 239, P=0. 030）, and mean urine output at seven days postoperatively（95%CI：1. 058-334. 543,OR：18. 813, P=0. 046）were identified as independent influencing factors for the occurrence of bladder spasms after kidney transplantation（P<0. 05）. Conclusions Renal transplant patients have a longer preoperative dialysis time, and the use of harder urinary catheter materials and lower postoperative urine output can increase the risk of postoperative bladder spasms. Therefore, it is necessary to increase nursing evaluation for high-risk patients with bladder spasms mentioned above, monitor postoperative urine output, and choose soft urinary catheters as much as possible to prevent the occurrence of bladder spasms after kidney transplantation.

目的 建立大鼠急性心肌梗死缺血再灌注后无复流模型,并初步验证细胞焦亡在其中的发生情况。方法 选用20只标准成年雄性Sprague Dawley大鼠（体质量260~320 g）,随机分为对照组（n=5）和手术组（n=15）。对照组仅穿线冠状动脉,未行结扎;手术组结扎左前降支0.5 h后解除,进行再灌注4 h,以建立无复流模型。通过Evens blue和硫磺素S染色,评估心肌的正常供血区、再灌注区及无复流区,并对两组大鼠心肌组织进行病理分析。结果 对照组大鼠全部存活,未出现无复流现象,心肌组织中未见细胞焦亡。手术组存活13只,形成明确的正常供血区（n=13）、再灌注区（n=13）和无复流区（n=10）。在无复流区的心肌细胞中均观察到细胞焦亡（n=10）,而正常供血区未见（n=0）,再灌注区部分出现（n=4）,差异具有统计学意义（P<0.05）。结论 细胞焦亡现象主要存在于大鼠急性心肌梗死缺血再灌注后无复流区域中,细胞焦亡可能作为一种区域特异性程序性死亡方式,在心肌无复流的发生与发展中发挥重要作用。

Objective To establish a rat model of myocardial no-reflow after acute myocardial infarction with ischemia-reperfusion injury and to preliminarily explore the occurrence of pyroptosis in the affected myocardium. Methods Twenty adult male Sprague-Dawley rats（260-320 g）were randomly divided into a control group（n=5）and a surgical group（n=15）. In the control group,the coronary artery was encircled with suture but not ligated. In the surgical group,the left anterior descending artery was ligated for 30 minutes, followed by 4 hours of reperfusion to induce the no-reflow model. Evans blue and thioflavin S staining were used to evaluate the normal perfusion area,reperfusion area,and no-reflow area of the myocardium. Histopathological analysis was conducted on myocardial tissues from both groups. Results All rats in the control group survived without evidence of no-reflow or pyroptosis in myocardial tissue. In the surgical group, 13 rats survived and showed distinct regions of normal perfusion, 13 with reperfusion, and 10 with no-reflow. Pyroptosis was observed in all no-reflow areas（n=10）, absent in the normal perfusion zones（n=0）, and partially present in the reperfusion zones（n=4）. The differences were statistically significant（P<0. 05）. Conclusions Pyroptosis predominantly occurs in the no-reflow zones following acute myocardial infarction and ischemia-reperfusion injury in rats. As a region-specific form of programmed cell death, pyroptosis may play an important role in the development of myocardial no-reflow.

Objective To explore the status and influencing factors of nausea and vomiting after radical resection of liver cancer. Methods A retrospective analysis was conducted on 70 liver cancer patients admitted to the Second People’s Hospital of Tianjin from May 2022 to May 2024. All patients underwent radical surgery for liver cancer,and their postoperative nausea and vomiting conditions were analyzed. According to the occurrence of nausea and vomiting, 30 patients who experienced nausea and vomiting after surgery were divided into an observation group, and the remaining 40 patients were divided into a control group. The clinical and pathological characteristics as well as perioperative indicators between two groups of patients were compared. A logistic regression model was established to analyze the influencing factors of postoperative nausea and vomiting in liver cancer patients after surgical resection,with postoperative nausea and vomiting as the dependent variable. Results The incidence of postoperative nausea and vomiting in liver cancer patients was 42. 86%（30/70）, including 14 cases of grade I, accounting for 20. 00%, 10 cases of grade II, accounting for 14. 29%, four cases of grade III,accounting for 5. 71%, and two cases of grade IV,accounting for 2. 86%. There were no significant differences in gender,body mass index（BMI）, pathological type,clinical stage,and preoperative fasting time between the observation group and the control group（P>0. 05）. However, there were significant differences in age and chemotherapy status between the observation group and the control group（P<0. 05）. There were no significant differences in the operation time,postoperative VAS score,anesthesia method and postoperative complications between the observation group and the control group（P>0. 05）, but with differences in the portal block time,intraoperative blood loss and postoperative abdominal distension between the observation group and the control group（P<0. 05）. Age, chemotherapy, intraoperative blood loss, and postoperative abdominal distension were independent influencing factors for postoperative nausea and vomiting in liver cancer patients undergoing surgical resection（P<0. 05）. Conclusions The incidence of nausea and vomiting after surgical resection in liver cancer patients is relatively high, with age, chemotherapy, intraoperative blood loss, and postoperative abdominal distension may be influencing factors for nausea and vomiting. Therefore, relevant measures should be taken in a timely manner to intervene in high-risk patients to prevent postoperative nausea and vomiting and reduce its severity.

Objective To establish a predictive model for medication compliance among acute heart failure（AHF）patients in order to enhance their therapeutic compliance and optimize clinical outcomes. Methods A total of 580 AHF inpatients at He Xian Memorial Hospital in Panyu District, Guangzhou between January 2021 and December 2023 were enrolled. Demographic information, disease-specific data,as well as post-discharge medication compliance records within six-month were collected by investigators. Utilizing logistic regression analysis revealed several influential determinants affecting medication compliance which formed the basis for constructing our predictive model. Results Generally,patient compliance was good（75%）. The comparison between the good compliance group and the poor compliance group showed that there were significant differences in age, living alone,combined with underlying diseases, types of medication, disease understanding score, treatment confidence score and self-control confidence score（P<0. 05）. Logistic regression analysis showed that independent risk indicators including individuals aged ≥60 years（odds ratio[OR]=1. 774）, those living alone（OR=1. 871）, presence of two or more underlying diseases（OR=1. 719）, along with consumption of seven or more medications daily（OR=1. 456）. Conversely,disease awareness score（OR=0. 923）, treatment confidence score（OR=0. 946）, and self-control confidence score（OR=0. 901）were identified as independent protective factors. Validation using receiver operating characteristic curves demonstrated robust predictive performance with an area under curve value of 0. 815（95%CI：0. 780-0. 850）, affirming its efficacy. The calibration of the model was evaluated, with a P-value of 0. 528, indicating good fit of the predictive model. Additionally, the concordance index（C-index）of the model was 0. 738, suggesting its excellent predictive performance. The decision curve analysis revealed that the curve was above the extreme lines, with a net benefit rate ranging from 0 to 27% when the threshold probability falls between. Conclusions The medication compliance of AHF patients is influenced by various factors, including age, living arrangement, the number of underlying diseases, and the number of medications taken. Targeted interventions such as enhancing patient education, simplifying treatment regimens, and improving social support can effectively improve the medication compliance of AHF patients. The predictive model established in this study provides a scientific basis for clinicians to develop more precise and effective individualized intervention measures,thereby improving the prognosis and quality of life.

Objective To evaluate the therapeutic efficacy of CO₂ laser treatment in cervical intraepithelial neoplasia grade 2（CIN2）patients. Methods We retrospectively analyzed data from 92 CIN2 patients who underwent CO₂ laser therapy at the institution from November 2021 to October 2023. Postoperative followed-up for 6-12 months, screening with liquid-based cytopathology test（LCT）and high-risk human papilloma virus（HPV）testing. Patients with abnormal results in either test were referred for colposcopy, with biopsy performed to evaluate residual or recurrent squamous intraepithelial lesions. Results Among total of 92 patients, most patients aged 25-45 years old, with a history of induced abortion, had three or more sexual partners, and visited hospital due to cervical lesions, and none of the patients gave birth. All patients were found to be HPV positive at hospital visits, with 20. 65% of HPV16 positive, 1. 09% of HPV18 positive, 60. 87% of other 12 kinds HPV positive, while HPV16 positive with other 12 kinds accounted for 17. 39%. Among the 79 patients after 6-month follow-up, the dual-negative conversion rate（HPV+LCT）was 74. 68%（59/79）, with LCT and HPV negative rates reaching 92. 41%（73/79）and 74. 68%（59/79）, respectively. After 12-month follow-up, all patients achieved LCT negativity, 29 patients with no documented lesion persistence or disease progression. Notably, patients aged <25 years exhibited the lowest postoperative HPV persistence rates between 6- to 12-month follow-up, whereas those aged 45-55 years demonstrated the highest persistence rates, frequently associated with HPV16 positivity or co-infection with other HPV subtypes. Conclusions CO₂ laser therapy significantly increases postoperative negative conversion rates for HPV and LCT. No lesion progression was observed in patients between 6- to 12-month follow-ups. The therapy also notably improves HPV clearance in younger patients. For patients with CIN2 who have fertility requirements and meet the indications, CO2 laser therapy should be actively adopted to achieve greater health benefits.

      Objective  To analyze the regularity and characteristics of the medical damage liability dispute with drug-induced disulfiram-like reaction, to avoid the risk of medication and provide reference for clinical rational drug use. Methods  China Judgements Online had been searched using the keywords of “disulfiram” from inception to March 25,2025. The evaluation table database was established with the excel table to conduct statistical analysis on the basic information of judgements, drug association, clinical performance,outcome of disease and the compensation. Results A total of 81 cases of judgements documents were retrieved,and 18 cases were enrolled. There were 3 tertiary hospitals, 5 second-class hospitals, 7 health-centers, 2 private hospitals,1 clinic among the medical establishments. Fifteen cases were male and 3 cases were female. The drugs suspected causing disulfiram-like reaction were cefoperazone, cefuroxime, tinidazole, cefotaxime, metronidazole, levofloxacin, ceftriaxone, cefotiam, cefminox. The interval between drinking and medication was usually 1-3 days. The symptoms were as follows：dyspnea/respiratory arrest, coma/loss of consciousness/shock, cyanosis /purple nails, convulsion/trembling, sweatiness, inability to speak/lack of clarity, etc. Fifteen cases ended in death, 1 was neurosis, 1 was first-degree disability (vegetative state), 1 was secondary disability (limb dysfunction after hypoxic encephalopathy). The identification of 7 cases of death was affected by the lack of autopsy. One case was settled and the outcome of the third trial was not announced in another case. The remaining 16 medical institutions took 10%-70% of the medical compensation liability, with the compensation amount ranging from 43 092. 4 yuan to 1 615 354 yuan. The main faults of the medical institutions were undetailed drinking history, irregular medication, breaches of duty of reasonable care, failure to fulfill the obligation of informed notification,etc. Conclusions Drug-induced disulfiram-like reaction has the characteristics of graveness of harm and rapid progress. Primary medical institutions need to improve their identification and disposal capacity urgently. Attention should be paid to collecting and recording of drinking history. Antibiotics should be used in a reasonable and compliant manner. Obligation of high attention to patients, information and other obligations should be fulfilled. Hospital pharmacy staff should ensure drug use safety through participating in drug education actively.
