Objective:To explore the distribution of cardiovascular disease(CVD)and cardiovascular risk fac-tors(CVRF)in patients with epithelial ovarian cancer before treatment and their correlation with the histological type,stage and grade of ovarian cancer.Methods:A total of 401 newly diagnosed epithelial ovarian cancer pa-tients admitted to The First Affiliated Hospital of Dalian Medical University from January 1,2015 to December 31,2022 were enrolled.Analyze the distribution of CVD(including hypertension,coronary heart disease,stroke,etc.)and CVRF(including diabetes,dyslipidemia,high level of uric acid)in epithelial ovarian cancer patients.Univari-ate analysis and multivariate Logistic regression were performed on the association between CVD,CVRF and the histological type,grade and stage of epithelial ovarian cancer.Results:①Among 401 epithelial ovarian cancer pa-tients,43.6％had at least one CVD before therapy.The most common CVD was hypertension(41.1％),and the most common CVRF was dyslipidemia(57.9％).②Multivariate Logistic regression analysis showed that age ≥60 years was an independent risk factor for serous,high-grade,and advanced epithelial ovarian cancer(OR＞1,P＜0.05).Dyslipidemia was an independent risk factor for high-grade and advanced epithelial ovarian cancer(OR＞1,P＜0.05).High level of uric acid was an independent risk factor for advanced epithelial ovarian cancer(OR＞1,P＜0.05).③The proportion of high-density lipoprotein cholesterol(HDL-C)and lipoprotein A[Lp(A)]abnor-malities in patients with advanced epithelial ovarian cancer was significantly higher than in those with early stage epithelial ovarian cancer(P＜0.05),and the proportion of number of abnormal lipid components was higher in pa-tients with high grade and advanced epithelial ovarian cancer than in patients with low grade and early stage epi-thelial ovarian cancer,respectively(P＜0.05).Conclusions:Patients with epithelial ovarian cancer bear a signifi-cant burden of CVD and CVRF.Hypertension is the most common CVD,and dyslipidemia is the most common CVRF.Dyslipidemia was associated with epithelial ovarian cancer grade and stage.High level of uric acid was as-sociated with epithelial ovarian cancer stage.Active control of blood pressure and blood lipid levels is very impor-tant for epithelial ovarian cancer patients.

Objective To investigate the relationship between plasma homocysteine(Hcy)levels and cognitive impairment(CI).Methods From November 2018 to January 2019,baseline data and cognitive function were collected from the participants aged≥40 years who lived in two villages in Huyi District,Xi'an,China.Their global cognitive function was assessed by Mini-Mental State Examination(MMSE)and the diagnosis of cognitive impairment was based on international guidelines.Fasting blood was collected in the morning,and plasma Hcy level was measured by the chemiluminometric assay.Multivariate Logistic regression analysis,subgroup analysis,and interaction analysis were performed to investigate the relationship between plasma Hcy and CI.Results A total of 1 805 subjects were included in the analysis.There were 1 056 females(58.5％),age ranged from 40 to 88 years[mean(58.99±9.52)years],and 145 participants(8.0％)were diagnosed as CI.The median plasma Hcy level in the overall population was 14.1(11.6,17.8)μmol/L.There were 729(40.4％)subjects in the HHcy group(＞15.0 μmol/L)and 1 076(59.6％)in the normal group(≤15.0 μmol/L).Univariate analysis showed that the prevalence of CI was higher in the HHcy group than in the normal Hcy group(11.4％vs.5.8％,P＜0.001).In multivariable Logistic regression fully adjusted for potential confounders,each 1 μmol/L increase in plasma Hcy level was associated with a 3.0％increased risk of CI(OR=1.030,95％CI:1.012-1.048,P=0.001).Interaction analysis indicated that sex,age,BMI,systolic blood pressure,history of stroke,and diabetes did not significantly modify this association.Conclusion Elevated plasma Hcy levels are associated with an increased risk of CI in people aged≥40 years.This indicates that HHcy may be a risk factor for CI.

AIM To establish an HPLC-MS/MS method for the simultaneous content determination of gallic acid,protocatechuic acid,oxypaeoniflorin,catechin,epicatechin,albiflorin,paeoniflorin,rutin,calycosin-7-glucoside,syringaldehyde,ferulic acid,coumarin,ononin,calycosin,cinnamic alcohol,cinnamic acid,benzoylpaeoniflorin,cinnamaldehyde,astragaloside,astragaloside Ⅲ,6-gingerol in Huangqi Guizhi Wuwu Decoction.METHODS The analysis was performed on a 30 ℃ thermostatic Thermo Scientific Hypersil GOLD column(150 mmx4.6 mm,3 μm),with the mobile phase comprising of 0.015％formic acid-acetonitrile flowing at 0.4 mL/min in a gradient elution manner,and electrospray ionization source was adopted in positive and negative ion modes with multiple reaction monitoring.RESULTS Twenty-one constituents showed good linear relationships within their own ranges(r＞0.990 5),whose average recoveries were 93.99％-108.52％with the RSDs of 1.04％-5.97％.CONCLUSION This simple,feasible,stable and reliable method can be used for the quality control of Huangqi Guizhi Wuwu Decoction.

Objective To investigate the effect of two treatment regimens combining Tacrolimus(TAC)with different Rituximab(RTX)dosages,and to provide clinical reference for treatment strategies.Methods A retrospective analysis was conducted on patients diagnosed with idiopathic membranous nephropathy(IMN)and treated with RTX combined with TAC regimen(RTX+TAC group and low-dose RTX+TAC group)in The First Affiliated Hospital of Xinxiang Medical University.Propensity score matching(PSM)was performed at a 1:1 ratio,and a total of 60 patients were enrolled,with 30 in each group.In low-dose RTX(375 mg/m2 at the first and fifteenth day respectively)+TAC group,if circulating B cells(CD19?)exceeded 5 cells/μL after 3 months,a 200 mg RTX infusion was administered.In RTX(1g at the first and fifteenth day respectively)+TAC group,if complete remission(CR)was not achieved by 6 months,an additional 1000 mg RTX infusion was administered.The incidence of CR,partial remission,and adverse events were followed up for 12 months after medication in both groups.Results(1)Both groups showed significant reductions in 24-hour proteinuria,with the RTX+TAC group demonstrating a notably higher decrease compared to the low-dose RTX+TAC group.Statistical differences were observed between the two groups at the 1st and 3rd months of treatment(P<0.05).Albumin levels gradually increased,and there were differ-ences between the two groups at both the 1st and 3rd months(P<0.05).The anti-phospholipase A2 antibody levels decreased significantly after one month of treatment[3.45(1.90,22.10)vs.3.28(8.30,23.08)RU/mL],P>0.05.At 3 months of treatment,the overall clinical remission rate was 63.3％for the RTX+TAC group compared to 36.7％for the low-dose RTX+TAC group(P<0.05).At 12 months,the RTX+TAC group achieved an overall remission rate of 86.7％,while the low-dose RTX+TAC group reached 83.3％,showing no statistical significance(P>0.05).After one month of treatment,the RTX+TAC group achieved a complete serological immunological remission rate of 33.3％,significantly higher than the 3.3％in the low-dose RTX+TAC group(P<0.05).(2)The cumulative remission rate of the RTX+TAC group was higher than that of the low-dose RTX+TAC group during the first 6 months of follow-up.The remission rate in the low-dose RTX+TAC group increased significantly after 6 months.Log-rank test showed no statistical difference between the survival curves of the two groups(P=0.37).(3)Based on a multifactorial COX regression analysis of factors related to remission in patients with IMN,for every unit increase in serum immunological remission time,the risk of patients achieving remission decreased by 13.5％(HR=0.87,P=0.016).The risk of remission for patients with high titers of anti-PLA2R antibodies decreased by 60.2％(HR=0.39,P=0.018).Conclusions Different RTX dosages yielded comparable overall clinical remission rates without significantly increasing adverse events.RTX+TAC regimen achieves higher early CR rate.Serological remission time and high titer anti-PLA2R antibodies are associated with clinical outcomes.

Objective To explore the clinical effect of applying an improved"outside-in"technique in hip arthroscopic surgery.Methods Totally 136 patients undergoing hip arthroscopic surgery between June 2021 and July 2023 were selected and studied retrospectively.According to their different surgi-cal approach,they were divided into a modified approach group(n=75,including 30 males and 45 fe-males,with an average age of 36±14)and a classic approach group(n=61,including 33 males and 28 females,with an average age of 31±11).Before as well as 4 weeks,3 months and 6 months after the surgery,both groups were evaluated using the visual analog scale(VAS)and Harris hip score,and observed their surgical complications.Moreover,the surgical outcomes and time of sur-gical approach establishment were compared between the two groups.Results There was no significant difference between the two groups in general information,preoperative VAS and Harris scores.More-over,no significant difference was found between the two groups in the Harris score after surgery.Compared with the classic approach group,the improved group had significantly less surgical time(49.0±16.9 min vs.66.0±13.3 min,P<0.05),without using the C-arm fluoroscopy during surgery.Moreover,in the modified approach group,the time for establishing the mid-anteriorapproach was sig-nificantly shortened(10.4±5.9 min vs.25.9±15.1 min,P<0.05),along with the traction time during surgery(66.0±13.3 min vs.49.0±16.9 min,P<0.05).Conclusion The modified"outside-in"hip ar-throscopy technique is a safe and effective surgical method,easier to operate,with shorter surgical time.

Objective Logistic regression model was used to analyze the risk factors of liver cancer in patients with hepatitis B virus-related cirrhosis. Methods A retrospective analysis was performed on 504 patients with hepatitis B cirrhosis who were treated in a hospital from April 2021 to April 2024. The occurrence of liver cancer was counted. The risk factors of liver cancer in patients with HBV-related cirrhosis were analyzed by logistic regression analysis. Results Among the 504 patients with hepatitis B cirrhosis, 101 patients developed liver cancer and 403 patients did not develop liver cancer, which were included in the liver cancer group (n=101) and the non-liver cancer group (n=403).. Among hepatitis B cirrhosis, the incidence rate of liver cancer was 20.04%. Compared with the non-liver cancer group, the proportion of patients with long-term drinking history, family history of liver cancer, history of diabetes mellitus, antiviral therapy, and HBV-DNA load>104 were higher in the liver cancer group (P<0.05). logistic regression analysis found that long-term drinking history (OR=3.077, 95%CI: 1.130-8.378, P=0.028), history of diabetes mellitus (OR=3.747, 95%CI: 1.765-7.954, P=0.001), no antiviral therapy (OR=3.466, 95%CI: 1.337-8.985, P=0.011) and HBV-DNA load>104 (OR=3.149, 95%CI: 1.353-7.328, P=0.008) could independently affect the occurrence of liver cancer in patients with hepatitis B cirrhosis. Conclusion According to logistic regression analysis, long-term drinking history, history of diabetes mellitus, no antiviral therapy, and HBV-DNA load>104 are risk factors for liver cancer in patients with HBV-related cirrhosis.
