目的 探讨肝脏衰弱程度联合肝功能分级预测肝硬化患者肝病复合不良事件的价值,作为识别和干预不良结局的依据。方法 选择2022年12月—2023年12月医院接收的肝硬化患者80例进行研究,随访6个月观察患者不良事件发生情况,将出现2个及以上肝病并发症的肝病复合不良事件患者25例作为观察组,将出现1个肝病并发症或未出现并发症的患者55例作为对照组,比较两组患者的基本资料、实验室指标、营养指标、体力活动水平、肝脏衰弱指数(LFI)、肝功能Child-Turcotte-Pugh(CTP)评分,采用单因素和多因素Cox回归分析评估肝硬化患者肝病复合不良事件的危险因素,使用受试者工作特征(ROC)曲线下面积评估LFI联合CTP评分预测肝硬化患者肝病复合不良事件的价值。结果 观察组年龄、丙氨酸氨基转移酶(ALT)高于对照组,红细胞计数(RBC)、血红蛋白(Hb)、血肌酐(Scr)、总胆红素(TBIL)、步速、小腿围低于对照组(t分别为4.235、6.500、3.826、3.989、4.289、8.878、2.474,均P<0.05)。观察组营养风险48.00%、LFI≥4.5分52.00%、CTP分级B/C级76.00%高于对照组18.18%、14.55%、27.27%(χ 2 分别为7.664、12.454、16.699,均P<0.05)。单因素Cox回归分析显示年龄、ALT、营养风险、LFI≥4.5分、CTP分级B/C级、RBC、Scr、TBIL、Hb、步速、小腿围为肝硬化患者发生肝病复合不良事件的危险因素(HR分别为2.251、1.578、1.626、1.981、1.715、1.428、1.443、1.419、1.336、1.332、1.254,均P<0.05)。多因素Cox回归分析显示年龄、ALT、营养风险、LFI≥4.5分、CTP分级B/C级为肝硬化患者发生肝病复合不良事件的独立危险因素(HR分别为2.275、1.746、2.025、1.895,P均<0.05)。ROC曲线结果显示LFI、CTP、LFI联合CTP预测肝硬化患者肝病复合不良事件的AUC分别为0.82、0.79、0.88(P<0.05)。结论 年龄、肝脏衰弱、CTP分级B/C级、营养风险为肝硬化患者肝病复合不良事件的危险因素,肝脏衰弱程度联合肝功能分级预测肝硬化患者肝病复合不良事件具有更高的效能。
Objective To explore the value of predicting liver disease complex adverse events in patients with liver cirrhosis by combining the degree of liver frailty with liver function grading,as a basis for identifying and intervening in adverse outcomes.Methods A study was conducted on 80 patients with liver cirrhosis admitted to the hospital from December 2022 to December 2023.Patients were followed up for six months to observe the occurrence of adverse events.Twenty-five patients with liver disease complex adverse events with two or more liver disease complications were selected as the observation group,and 55 patients with one or no liver disease complication were selected as the control group.The basic information,laboratory indicators,nutritional indicators,physical activity levels,liver frailty index(LFI),Child Turcotte Pugh(CTP)scores,univariate and multivariate Cox regression analysis were used to evaluate the risk factors for liver disease complex adverse events in liver cirrhosis patients.The value of combining LFI and CTP score in predicting liver disease complex adverse events in patients with liver cirrhosis was assessed by Receiver Operating Characteristic (ROC)curve area.Results The age,alanine aminotransferase(ALT),red blood cell count(RBC),hemoglobin(Hb),serum creatinine(Scr),total bilirubin(TBIL),walking speed,and calf circumference of the observation group were higher than those of the control group(t=4.235,6.500,3.826,3.989,4.289,8.878,2.474,all P<0.05).The nutritional risk of the observation group was 48.00%,LFI score≥4.5 was 52.00%,CTP grade B/C was 76.00%,which was higher than that of the control group at 18.18%,14.55%,and 27.27%(χ 2 =7.664,12.454,16.699,all P<0.05).Univariate Cox regression analysis showed age,nutritional risk,LFI ≥ 4.5,CTP grade B/C,RBC,Scr,TBIL,Hb,step speed and calf circumference were risk factors for the occurrence of liver disease complex adverse events in patients with liver cirrhosis(HR values=2.251,1.578,1.626,1.981,1.715,1.428,1.443,1.419,1.336,1.332,1.254,all P<0.05).Multivariate Cox regression analysis showed that age,ALT,nutritional risk,LFI ≥ 4.5,and CTP grade B/C were independent risk factors for liver disease complex adverse events in patients with liver cirrhosis(HR values=2.275,1.746,2.025,1.895,all P<0.05).The ROC curve results showed that the AUC of LFI,CTP,and LFI combined with CTP in predicting liver disease composite adverse events in patients with liver cirrhosis were 0.82,0.79,and 0.88,respectively(P<0.05).Conclusions Age,liver frailty,CTP grade B/C,and nutritional risk are risk factors for liver disease complex adverse events in patients with liver cirrhosis.The combination of LFI and liver function grade has higher efficacy in predicting liver disease complex adverse events in patients with liver cirrhosis.

Objective To explore the clinical efficacy of immune and targeted drugs combined with hepatic artery infusion chemotherapy(HAIC)in the treatment of advanced liver cancer.Methods A retrospective analysis was conducted on 78 patients with advanced liver cancer admitted to our hospital from January 2021 to January 2024.Among them,20 patients were treated with simple HAIC and divided into a single chemotherapy group.Thirty patients were treated with HAIC combined with PD-1 antibody,and divided into an immune group.Twenty-eight patients were treated with HAIC combined with PD-1 antibody immunotherapy and lenvatinib mesylate capsule targeted therapy,and divided into a combination group.The clinical efficacy of three groups,the expressionlevels of CEA,CA125,AFP,and incidence of adverse reactions before and after treatment were compared.Piper Fatigue Correction Scale(PFS-R)and the WHO QOL-BREF were used to assess cancer-related fatigue in both groups.The degree of fatigue and quality of life were assessed.Results The objective response rates of the simple chemotherapy group,the immune group,and the combination group were 15.00%,40.00% and 64.29%,respectively.The disease control rates were 30.00%,66.67% and 82.14%,respectively.The indicators above of the combination group was significantly higher than those in the simple chemotherapy group and the immune group(χ 2 =11.720,P=0.003;χ 2 =13.890,P<0.001;P<0.05).After treatment,the levels of CEA,CA125 and AFP were all decreased in the three groups,and those in the combined group (CEA[13.62±4.24]ng/mL,CA125[31.62±13.66]U/mL,AFP:Ng/mL[35.21±5.93])were lower than those in the immune group(17.85±3.32 ng/mL,59.26±9.35 U/mL,/ 42.12±4.12 ng/mL)and single chemotherapy group(23.73±4.79 ng/mL,64.57±5.23 U/mL47.46±5.32]ng/mL),the differences were statistically significant(F=7.698,P<0.001;F=11.480,P<0.001;F=14.952,P<0.001;P<0.05).All patients had no grade 5 adverse reactions or severe liver function damage,and there was no statistically significant difference in the incidence adverse reactions such as thrombocytopenia,leukopenia,abdominal pain,vomiting,gastrointestinal bleeding,and anorexia among the three groups(P>0.05).After treatment,the PFS-R score of the three groups was decreased,and the combined group(3.85±1.13)score was lower than that of the immune group(5.39±1.25)and the chemotherapy group(6.33±1.26).While the WHOQOL-BREF score was increased,the score of combination group(348.58±66.12)was higher than that of immune group(297.24±72.21)and chemotherapy group(256.35±41.67),and the difference was statistically significant(F=2.526,P=0.014;F=2.167,P=0.033;P<0.05).Conclusions The combination of immune and targeted drugs with hepatic artery infusion chemotherapy has a significant therapeutic effect on advanced liver cancer.It can effectively control disease progression,reduce tumor marker levels in the body,improve patient quality of life,and alleviate cancer-related fatigue,with controllable safety
目的 探讨剖宫产后再次分娩阴道试产失败的影响因素。方法 选取2021年5月—2024年5月在枣庄市妇幼保健院分娩的138例有剖宫产手术史的足月妊娠产妇进行回顾性分析。所有产妇依照其阴道试产结果将成功阴道分娩的35例产妇分为成功组,将阴道试产失败中转剖宫产的103例产妇分为失败组。对比两组产妇的妊娠结局、孕期情况及围产期情况,最后采用多因素Logistic回归分析法分析剖宫产后再次分娩阴道试产失败的影响因素。结果 两组产妇子宫破裂、胎儿窘迫、产褥感染及产后出血等妊娠不良结局总发生率对比差异无统计学意义(11.43% vs 6.80%,χ 2 =0.760,P=0.382 >0.05);通过对比两组产妇孕期情况发现,失败组与成功组孕妇年龄、孕次、身高、孕前体质量、妊娠期合并症、分娩前体质量指数(BMI)比较差异无统计学意义(P>0.05),失败组与成功组孕妇孕期体质量增长[(4.56±2.56)kg vs(12.45±3.24)kg]、分娩孕周[(39.46±1.25)周 vs(37.95±1.37)周]、阴道分娩史(8.57% vs 26.21%)、妊娠间隔时间[(2.74±0.35)年 vs(3.37±0.57)年]及瘢痕厚度[(4.51±0.56)mm vs(5.42±0.38)mm],对比差异有统计学意义(t=3.497,P<0.001;t=5.755,P<0.001;χ 2 =4.780,P=0.029;t=6.148,P<0.001;t=10.764,P<0.001);通过对比两组产妇围产期情况发现,失败组与成功组新生儿性别、是否镇痛比例比较差异无统计学意义(P>0.05),失败组与成功组孕妇产前新生儿估重[(3352.31±153.67)g vs(3046.25±141.68)g]、是否引产[60.00% vs 52.43%]、胎膜早破[11.43% vs 35.92%]、入院时是否临产[857% vs 27.18%],对比差异有统计学意义(t=10.805,P<0.001;χ 2 =7.330,P=0.007;χ 2 =7.500,P=0.006;χ 2 =5.200,P=0.023);以阴道试产情况作为因变量(失败=1,成功=0)纳入Logistic回归模型,结果显示,分娩孕周过晚、产前新生儿估重过高、引产及入院时未临产为剖宫产后再次分娩阴道试产失败的影响因素(P<0.05)。结论 分娩孕周过高、产前新生儿估重过高、引产及入院时未临产为剖宫产后再次分娩阴道试产失败的独立影响因素,需针对分娩孕周、产前新生儿估重过高的剖宫产后再次分娩阴道试产产妇给予高度关注并采取相应措施进行干预,同时自然临产能够降低阴道试产失败风险,但针对具有引产指征的产妇,依然需要及时引产。
Objective To explore the influencing factors of vaginal trial delivery failure after cesarean section.Methods A retrospective analysis was conducted on 138 full-term pregnant women with a history of cesarean section who gave birth in our hospital from May 2021 to May 2024.All women were divided into two groups according to the results of their vaginal trial delivery.Based on their vaginal trial results,35 parturients who successfully delivered were divided into the successful group,and 103 parturients who failed vaginal trial delivery and transitioned to cesarean section were divided into the failed group.The pregnancy outcomes of postpartum women and the pregnancy and perinatal conditions were compared between the two groups,and multivariate Logistic regression analysis was used to analyze the independent influencing factors of vaginal trial delivery failure after cesarean section.Results There was no significant difference in the total incidence of adverse pregnancy outcomes such as uterine rupture,fetal distress,postpartum infection,and postpartum hemorrhage between the two groups of parturients (P>0.05).By comparing the pregnancy status of two groups of pregnant women,it was found that there was no difference (P>0.05).The average weight gain during pregnancy of failure and successful group,gestational age,cases with vaginal delivery history,intervalbetween pregnancy and scar thickness,the contrast difference was significant (all P<0.05) .By comparing the perinatal situation of the two groups,there was no difference in the sex of fetus and analgesia receiving of parturients between the failed group and the successful group (P>0.05),while there is difference in weight estimation,whether induced labour,premature rupture of fetal membrane,whether admitted to hospital (all P<0.05).Vaginal trial delivery was set as the dependent variable (failure=1,success=0) and it was incorporated into the Logistic regression model.The results showed that high gestational age during delivery,high estimated weight of fetus before delivery,induction of labor,and non-labor upon admission were independent influencing factors for vaginal trial delivery failure after cesarean section (P<0.05).Conclusions Excessive gestational age,high estimated weight of fetus before delivery,induced labor,and non-labor upon admission were independent influencing factors for the failure of vaginal trial delivery after cesarean section.It is necessary to pay high attention and take corresponding measures to intervene in women who have undergone vaginal trial delivery after cesarean section due to excessive gestational age and high estimated weight of fetus before delivery.At the same time,spontaneous labour can reduce the risk of vaginal trial delivery failure.However,for women with indications for induced labor,timely induction is still necessary.
目的 探讨白蛋白-胆红素(ALBI)联合中性粒细胞与淋巴细胞比值(NLR)预测肝硬化合并食管胃底静脉曲张破裂出血(EGVB)的临床价值。方法 回顾性分析2021年1月—2022年12月肇庆市第一人民医院消化内科收治的80例肝硬化合并EGVB患者的临床资料,通过电话及门诊、再入院对其进行为期1年的随访,根据随访结果,将其分为2组,即存活组(n=69)与死亡组(n=11),分析导致患者死亡的危险因素,并评估ALBI联合NLR预测肝硬化合并EGVB患者死亡的临床价值。结果 死亡组的年龄60岁以上、腹水和肝性脑病者占比,总胆红素(TBiL)、NLR、凝血酶原时间(PT)、谷丙转氨酶(ALT)水平及ALBI评分均高于存活组(均P<0.05),而血红蛋白(HGB)、白蛋白(ALB)及血钠水平均低于存活组(均P<0.05);Logtisic回归分析显示,年龄60岁以上、腹水、肝性脑病和TBiL、NLR水平升高及ALBI分级为3级是肝硬化合并EGVB患者死亡的危险因素(均P<0.05);ALBI联合NLR预测肝硬化合并EGVB患者预后的准确率及灵敏度高于单一诊断,漏诊率低于单一诊断(P<0.05)。结论 肝硬化合并EGVB患者可见ALBI评分及NLR水平升高,而以上两种指标是患者死亡的危险因素,将其联合检测可评估患者预后,预测其死亡风险。
Objective To investigate the clinical value of albumin-bilirubin(ALBI)combined with neutrophil lymphocyte ratio(NLR)in predicting liver cirrhosis complicated with esophageal and gastric varices bleeding(EGVB).Methods The clinical data of 80 patients with liver cirrhosis complicated with EGVB admitted to the Department of Gastroenterology of the First People’s Hospital of Zhaoqing from January 2021 to December 2022 were retrospectively analyzed.They were followed up for one year by telephone,outpatient service and readmission.According to the follow-up results,they were divided into the survival group(n=69)and the death group(n=11).The risk factors leading to the death of patients were analyzed and evaluated.Results The proportion of age over 60,ascites and hepatic encephalopathy,the levels of TBiL,NLR,PT,ALT and ALBI in the death group were higher(P<0.05),while the levels of HGB,ALB and blood sodium were lower(P<0.05).Logistics analysis showed that age over 60,ascites,hepatic encephalopathy,NLR and ALBI grade 3 were independent risk factors for the death(P<0.05).The accuracy and sensitivity of ALBI combined with NLR in predicting their prognosis were significantly higher than that of single diagnosis,and the missed diagnosis rate was lower(P<0.05).Conclusions ALBI scores and NLR levels significantly increase in patients with liver cirrhosis complicated with EGVB,and the above two indexes are risk factors for the death,and the combination of them can evaluate the prognosis of patients and predict the death risk.
结直肠癌(CRC)是全球第三大最常见的癌症,也是癌症相关死亡的第二大常见原因。结直肠癌肝转移(CRLM)是导致CRC患者死亡的主要原因,根治性肝切除术是目前有望治愈CRLM的唯一途径,但大部分患者不能进行根治性肝切除术。通过早期发现并进行针对性干预,能够改善患者的治疗效果及预后。文章通过综述CRLM的发病机制、诊疗现状及最新纳米诊疗方法,为深入探索高效诊疗方法提供思路。
Colorectal cancer(CRC)is the third most common cancer and the second most common cause of cancer-related death worldwide.Colorectal cancer liver metastases(CRLM)are the leading cause of death in patients with CRC.Radical hepatectomy is the only way to cure CRLM so far,while most patients cannot undergo radical hepatectomy.CRLM treatment efficacy and prognosis can be improved by early diagnosis and specialized intervention.This paper reviews the pathogenesis,diagnosis,and treatment status of CRLM and the latest nano-diagnosis and treatment methods so as to provide ideas for in-depth exploration of efficient diagnosis and treatment methods.
目的 探讨阴道分娩后尿失禁患者疾病应对方式的影响因素。方法 选取2022年1月—2023年1月医院收治的阴道分娩后尿失禁患者78例,评估所有患者的应对方式,根据结果分为积极应对组与消极应对组,设计基线资料调查表,详细统计两组患者的基线资料并比较,重点分析阴道分娩后尿失禁患者疾病应对方式的影响因素。结果 经评估,78例阴道分娩后尿失禁患者疾病消极应对有40例,占比51.28%;积极应对组与消极应对组患者的产次(χ 2 =4.110,P=0.043)、文化水平(Z=2.094,P=0.036)、家庭关怀度(Z=2.069,P=0.040)与自我效能(Z=2.249,P=0.025)比较差异有统计学意义,组间年龄(t=0.096,P=0.924)、孕次(t=1.257,P=0.212)、体质指数(BMI)(t=0.125,P=0.901)、工作(χ 2 =0.778,P=0.378)、家庭月人均收入(χ 2 =0.044,P=0.834)、漏尿(χ 2 =0.040,P=0.842)比较差异无统计学意义;经回归分析发现,家庭关怀度低(OR=1.799,P=0.041)、自我效能低(OR=1.942,P=0.026)、经产妇(OR=2.554,P=0.045)及文化水平低(OR=1.837,P=0.038)均是阴道分娩后尿失禁患者疾病应对方式的影响因素。结论 阴道分娩后尿失禁患者疾病消极应对风险高,可能与产次、文化水平、家庭关怀度及自我效能有关。
Objective To explore the influencing factors of disease coping strategies in patients with urinary incontinence after vaginal delivery.Methods A total of 78 patients with urinary incontinence after vaginal delivery admitted to the hospital from January 2022 to January 2023 were selected.The coping strategies of all patients were evaluated,and they were divided into a positive coping group and a negative coping group based on the results.A baseline data questionnaire was designed,and the baseline data of the two groups of patients were compared in detail.The focus was on analyzing the factors influencing the disease coping strategies of patients with urinary incontinence after vaginal delivery.Results After evaluation,40 out of 78 patients with urinary incontinence after vaginal delivery had negative coping strategies,accounting for 51.28%.The parity of patients in the positive and negative coping groups(χ 2 =4.110,P=0.043),educational level(Z=2.094,P=0.036),family care(Z=2.069,P=0.040),and self-efficacy(Z=2.249,P=0.025)among the groups were different.Age between groups(t=0.096,P=0.924),gestational age(t=1.257,P=0.212),body mass index(t=0.125,P=0.901),and work experience(χ 2 =0.778,P=0.378),monthly per capita income of households(χ 2 =0.044,P=0.834),urinary leakage(χ 2 =0.040,P=0.842)had no statistically significant difference in comparison.Through regression analysis,it was found that low family care(OR=1.799,P=0.041),low self-efficacy(OR=1.942,P=0.026),postpartum women(OR=2.554,P=0.045),and low educational level(OR=1.837,P=0.038)were all influencing factors on the disease coping strategies of patients with urinary incontinence after vaginal delivery.Conclusions Patients with urinary incontinence after vaginal delivery have a higher risk of negative coping with the disease,which may be related to parity,educational level,family care and self-efficacy.

Objective To analyze the diagnostic efficacy of aspartate aminotransferase(AST),cholinesterase(CHE),carbohydrate antigen 125(CA125),and alpha fetoprotein(AFP)in patients with liver cirrhosis.Methods A total of 70 patients with liver cirrhosis were included in the observation group as the study subjects,and 70 healthy individuals who underwent physical examinations during the same period were selected as the control group.Both groups of research subjects underwent biochemical testing and tumor marker testing.The AST,CHE,CA125,and AFP detection results of two groups of research subjects were compared,and the diagnostic effect of the above indicators on patients with liver cirrhosis were analyzed.Results The CHE test results of patients with liver cirrhosis in the observation group were significantly lower than those of healthy individuals undergoing physical examination,and the AST,CA125,and AFP test results were higher(P<0.05).AST and CHE had good sensitivity and specificity in the diagnosis of liver cirrhosis.The sensitivity,specificity and coincidence rate of CA125 combined with AFP were higher than those of CA125 or AFP alone.Conclusions AST,CHE,CA125,and AFP have good clinical application performance in the diagnosis of liver cirrhosis patients,and are important reference indicators reflecting the progression of liver cirrhosis in patients.
目的 探讨多梳蛋白SUZ12对肝细胞肝癌(HCC)细胞增殖、血管生成拟态形成和人脐静脉内皮细胞(HUVECs)血管生成的影响。方法 分别利用MTT比色法及体外血管生成实验检测SUZ12表达水平改变对HCC细胞SMMC-7721、Hep3B增殖、血管生成拟态形成和HUVECs血管生成的影响。结果 MTT结果显示,在HCC细胞中分别敲低或过表达SUZ12均对HCC细胞的增殖能力无明显影响。将SUZ12低表达HCC细胞与HUVECs共培养后,HCC细胞的血管生成拟态管样结构形成增多。此外,将SUZ12敲低组HCC细胞的培养上清用于培养HUVECs后,HUVECs的血管生成拟态管样结构形成也明显增多。结论 SUZ12对HCC细胞的增殖无影响,其在HCC中可抑制HCC细胞和HUVECs的血管生成拟态管样结构形成。上述结果提示SUZ12可能通过调控HCC细胞及HUVECs的血管生成发挥抑癌作用。
Objective To investigate the effects of SUZ12 on cell proliferation of hepatocellular carcinoma(HCC),vasculogenic mimicry formation and human umbilical vein endothelial cells(HUVECs)angiogenesis.Methods MTT assay was performed to detect the proliferation of SMMC-7721 and Hep3B cells.The effects of SUZ12 on the angiogenesis of HCC cells and HUVECs cells were studied by in vitro angiogenesis experiment.Results The result of MTT assay showed that SUZ12 knockdown or overexpression in HCC cells had no significant effect on the proliferation of HCC cells.We found that when HCC cells with low SUZ12 expression were co-cultured with HUVECs cells,the formation of vasculogenic mimicry tubular structures in HCC cells increased.In addition,we also found that after the culture supernatant of HCC cells in the SUZ12 knockdown group was used to culture HUVECs cells,the formation of vasculogenic mimicry tubular structures in HUVECs cells also increased significantly.Conclusions SUZ12 has no effect on the proliferation of HCC cells,but it can inhibit the formation of vasculogenic mimicry tubular structures in HCC cells and HUVECs cells.These results suggest that SUZ12 plays a role in cancer inhibition by regulating the angiogenesis of HCCcells and HUVECs cells.
