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.

Compared with normal tissue cell microenvironment, there is some differences in tumor microenvironment, such as partial acidity, imbalance of redox state, high concentration of reactive oxygen species and cathepsin. According to the above characteristics of tumor microenvironment, a series of small molecule or polymer prodrug nanoparticles connected by various special microenvironment responsive structures can be designed. Doxorubicin, as one of the most common broad-spectrum antitumor drugs, plays an important role in the treatment of tumors. This review discusses the doxorubicin prodrug designed for different tumor microenvironments under the physiological state of tumor microenvironment specificity and their release characteristics, and summarizes the research progress of tumor microenvironment-responsive doxorubicin prodrug.

        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 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.

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 whether total burden of cerebaral small vessel disease（CSVD）detected with MRI was associated with the executive functions in patients with Parkinson's disease（PD）．Methods  In total，156 patients with PD in First People’s Hospital of Foshan from January 2020 to June 2024 were retrospectively enrolled．Detailed clinical data were obtained．The clinical data of all the patients such as age，gender，years of education，hypertension history were collected．The MiniMental State Examination（MMSE）and the Montreal Cognitive Assessment Scale（MoCA）were used to assess cognitive function，the Frontal Assessment Battery（FAB）was used to assess executive function．According to the function levels，all cases were divided into PD with normal cognition（PD-NC）group，PD with executive function（PD-EF）and PD with non-executive function（PD-NEF）．All the patients underwent brain MRI to determine the presence and burden of CSVD，scoring between 0 and 4．Results  The age，course of disease，Hoehn-Yahr staging，the scores of periventricular white matter hyperintensities（PWMH），the scores of deep subcortical white matter hyperintensities（DWMH），the numbers of lacunar infarcts（LI），the CSVD scores were significantly higher in the patients of PD-EF group than PD-NC group and PD-NEF group（P＜0.05）．Spearman’s correlation analysis showed that FAB scores had a significant correlation with scores of PWMH，the scores of DWMH，the numbers of LI，and the CSVD burden scores（P＜0.05）．Multivariable analysis showed that there was a significant negative correlation between FAB scores and the scores of DWMH，the numbers of LI，the CSVD scores．Conclusions  The total MRI CSVD burden was associated with the executive functions in patients with PD in this study．
