Background::Cardiovascular disease (CVD) has emerged as the leading cause of death from prostate cancer (PCa) in recent decades, bringing a great disease burden worldwide. Men with preexisting CVD have an increased risk for major adverse cardiovascular events when treated with androgen deprivation therapy (ADT). The present study aimed to explore the prevalence and risk evaluation of CVD among people with newly diagnosed PCa in China.Methods::Clinical data of newly diagnosed PCa patients were retrospectively collected from 34 centers in China from 2010 to 2022 through convenience sampling. CVD was defined as myocardial infarction, arrhythmia, heart failure, stroke, ischemic heart disease, and others. CVD risk was estimated by calculating Framingham risk scores (FRS). Patients were accordingly divided into low-, medium-, and high-risk groups. χ2 or Fisher’s exact test was used for comparison of categorical variables. Results::A total of 4253 patients were enrolled in the present study. A total of 27.0% (1147/4253) of patients had comorbid PCa and CVD, and 7.2% (307/4253) had two or more CVDs. The enrolled population was distributed in six regions of China, and approximately 71.0% (3019/4253) of patients lived in urban areas. With imaging and pathological evaluation, most PCa patients were diagnosed at an advanced stage, with 20.5% (871/4253) locally progressing and 20.5% (871/4253) showing metastasis. Most of them initiated prostatectomy (46.6%, 1983/4253) or regimens involving ADT therapy (45.7%, 1944/4253) for prostate cancer. In the present PCa cohort, 43.1% (1832/4253) of patients had hypertension, and half of them had poorly controlled blood pressure. With FRS stratification, as expected, a higher risk of CVD was related to aging and metabolic disturbance. However, we also found that patients with treatment involving ADT presented an originally higher risk of CVD than those without ADT. This was in accordance with clinical practice, i.e., aged patients or patients at advanced oncological stages were inclined to accept systematic integrative therapy instead of surgery. Among patients who underwent medical castration, only 4.0% (45/1118) received gonadotropin releasing hormone antagonists, in stark contrast to the grim situation of CVD prevalence and risk.Conclusions::PCa patients in China are diagnosed at an advanced stage. A heavy CVD burden was present at the initiation of treatment. Patients who accepted ADT-related therapy showed an original higher risk of CVD, but the awareness of cardiovascular protection was far from sufficient.

Objective To analyze the risk factors of gastrointestinal bleeding in patients with type A aortic dissection(TAAD)after Sun's operation.Methods The clinical data of 87 patients who underwent TAAD Sun's operation in our hospital from March 2021 to June 2022 were retrospectively analyzed.They were divided into the bleeding group and the non-bleeding group according to whether there was gastrointestinal bleeding after operation.The clinical data of patients in the two groups was compared and analyzed.The binary Logistic regression analysis was used to analyze the risk factors of gastrointestinal bleeding.The clinical predictor of postoperative gastrointestinal bleeding was analyzed by receiver operating characteristic(ROC)curve.Results In this study,there were 40 cases of postoperative gastrointestinal bleeding(the bleeding group)and 47 cases of non-bleeding(the non-bleeding group).Compared with the non-bleeding group,the bleeding group had a shorter onset time,a higher proportion of patients with hypertension history,a higher preoperative creatinine abnormality rate,more intraoperative blood loss,longer postoperative mechanical ventilation time,higher postoperative infection rate,and higher poor prognosis rate,with statistically significant differences(P<0.05).There was no statistically significant difference in the gender,age,gastrointestinal diseases history,smoking history,preoperative platelets,preoperative international normalized ratio(INR),preoperative alanine aminotransferase(ALT),preoperative aspartate aminotransferase(AST),preoperative γ-glutamyl transpeptidase(GGT),preoperative dissection involving abdominal aorta,operation time,intraoperative cardiopulmonary bypass time,intraoperative circulatory arrest time,intraoperative aortic occlusion time or intraoperative blood transfusion rate.Logistic regression analysis showed that hypertension history(OR=2.468,95%CI:0.862 to 7.067,P=0.037),preoperative creatinine>105 μmol/L(OR=3.970,95%CI:1.352 to 11.659,P=0.011),long postoperative mechanical ventilation time(OR=1.015,95%CI:0.094 to 1.018,P=0.041)and postoperative infection(OR=3.435,95%CI:0.991 to 11.900,P=0.012)were the independent risk factors for postoperative gastrointestinal bleeding in TAAD patients.ROC curve showed that the postoperative mechanical ventilation time exceeding 64 hours were the clinical predictor of postoperative gastrointestinal bleeding in TAAD patients.Conclusion The prognosis of TAAD patients with postoperative gastrointestinal bleeding after Sun's operation is poor.Hypertension history,preoperative acute renal insufficiency,long postoperative mechanical ventilation time and postoperative infection are closely related to postoperative gastrointestinal bleeding in TAAD patients after operation,which should be paid more attention to,and corresponding evaluation,early identification and early intervention should be made to improve the prognosis of patients.

Perihilar cholangiocarcinoma(PHC)is a common malignancy of biliary tract,for which surgery is the most effective treatment.However,its prognosis is not satisfactory even after surgical resection.In recent years,there have been some new advances in the surgical treatment of PHC.In this paper,we reviewed the existing literatures,demonstrated the current situation of preoperative biliary drainage,liver hyperplasia,hepatic resection,liver transplantation and minimally invasive surgery in the treatment of PHC,and prospected the future research direction.

Objective:To explore the therapeutic efficacy and prognostic factors of induction therapy for secondary central nervous system lymphoma(SCNSL).Methods:Clinical data of patients diagnosed with SCNSL from 2010 to 2021 at Guangdong Provincial People's Hospital were retrospectively collected.A retrospective cohort study was performed on all and grouped patients to analyze the efficacy and survival.Multivariate logistic regression analysis was used to explore the adverse prognostic factors.Results:Thirty-seven diffuse large B-cell lymphoma patients with secondary central involvement were included in the research.Their 2-year overall survival(OS)rate was 46.01％and median survival time was 18.1 months.The 2-year OS rates of HD-MTX group and TMZ group were 34.3％and 61％,median survival time were 8.7 and 38.3 months,and median progression-free survival time were 8.1 and 47 months,respectively.Multivariate logistic regression analysis showed that age,sex,IPI,Ann Arbor stage were correlated with patient survival time.The median survival time of patients with CD79B,KMT2D,CXCR4.ERBB2,TBL1XR1,BTG2,MYC,MYD88,and PIM1 mutations was 8.2 months,which was lower than the overall level.Conclusion:HD-MTX combined with TMZ as the first-line strategy may improve patient prognosis,and early application of gene sequencing is beneficial for evaluating prognosis.

Objective To explore the effect and possible mechanism of berberine on the macro-phage polarization of human myeloid leukemia monocytic cell line THP-1 induced by oxidized low-density lipoprotein(ox-LDL).Methods THP-1 cells were induced into macrophages by PMA,and then according to different concentrations of berberine,the cells were divided into con-trol group,and 5,10,20,40 and 50 μmol/L berberine groups.After intervention for 24 or 48 h,CCK8 assay was used to detect cell viability for optimal concentration and time of berberine treat-ment.PMA-induced THP-1 macrophages were assigned into blank group,model group(ox-LDL),berberine group,inhibitor group(phosphatidyl inositol 3-kinase(PI3K)inhibitor LY294002)and berberine+inhibitor group(berberine+LY294002).The contents of inducible nitric oxide syn-thase(iNOS)and TGF-β1 were detected by ELISA.qPCR was employed to measure the mRNA expression of TNF-α,arginase 1(Arg1),PI3K and protein kinase B Akt1,and Western blotting was applied to detect the protein levels of Akt1 and phosphorylated protein kinase B antibody(p-Akt1).Results In 24 h after intervention,the macrophage activity was significantly lower in the 40 and 50 μmol/L berberine groups than the control group(P＜0.05),and after 48 h,the ac-tivity in all the 5 doses of berberine groups was obviously lower than that in the control group[(0.89±0.02)％,(0.82±0.03)％,(0.71±0.02)％,(0.62±0.03)％and(0.53±0.02)％vs(1.01±0.01)％,P＜0.05].Berberine treatment of 20 μmol/L for 24 h had little effect on cell viability,and the dose and the time were regarded as the best concentration and time.Compared with the blank group,iNOS content and TNF-α mRNA level were increased in the model group,while TGF-β1 content,mRNA levels of Arg1,PI3K and Akt1,and p-Akt1/Akt1 protein levels were de-creased(P＜0.05).iNOS content and TNF-α mRNA level were decreased,while TGF-β1 content,mRNA levels of Arg1,PI3K and Akt1 and protein levels of p-Akt1/Akt1s were increased in the berberine group than the model group(P＜0.05).Compared with the berberine group,iNOS con-tent and TNF-α mRNA level were increased,while mRNA levels of Arg1,PI3K and Akt1 and protein levels of p-Akt1/Akt1 were decreased in the berberine+inhibitor group(P＜0.05).Con-clusion Berberine can inhibit the inflammatory response of THP-1 macrophages induced by ox-LDL by activating PI3K/Akt1 pathway,and inhibit the M1 polarization and promote the M2 polarization of macrophages.

Objective:To investigate the clinical effect of magnetic stimulation combined with moxibustion on mild to moderate overactive bladder(OAB)and sexual function in women.Methods:We enrolled 80 female patients with mild to moderate OAB in this study and equally randomized them into a control and an experimental group,the former treated by magnetic stimulation and the latter by magnetic stimulation combined with moxibustion,both for 8 weeks.We obtained from the patients their OAB syndrome scores(OABSS),72-hour urination diary(72-h UD)scores,International Consultation on Incontinence Questionnaire-Overactive Bladder(ICIQ-OAB)scores and female sexual function indexes(FSFI),and compared them between the two groups before and after interven-tion.Results:A total of 77 patients completed the study,37 in the control and 40 in the experimental group.There were no statisti-cally significant differences in the baseline data between the two groups(P＞0.05).Compared with the baseline,the experimental group showed significant improvement after treatment in the OABSS(7.54±1.12 vs 4.46±0.96),72-h urine volume([126.40±46.04]vs[216.63±38.26]ml),urination frequency(15.55±3.21 vs 8.03±1.40),ICIQ-OAB score(10.25±1.15 vs 6.32±1.07)and FSFI(20.00±12.40 vs 33.30±21.00)(all P＜0.05),even more significantly than in the control group(OABSS:4.46±0.96 vs 5.59±0.90;72-h urine volume:[216.63±38.26]vs[173.41±15.55]ml;urination frequency:8.03±1.40 vs 9.90±1.49;ICIQ-OAB score:6.32±1.07 vs 7.89±0.77;FSFI:33.30±21.00 vs 30.40±10.40)(all P＜0.01).Conclu-sion:Magnetic stimulation combined with moxibustion can improve the symptoms of mild to moderate overactive bladder and improve sexual function in females.

Objective To evaluate the efficacy of double U-stitch and modified"double U-stitch pancreaticojejunostomy"in pancreaticoduodenectomy.Methods We retrospectively analyzed the clinical information of 150 patients who underwent pancreaticoduodenectomy between January 2022 and September 2023 in Wang Wei's team in department of pancreatic surgery,Fudan University Shanghai Cancer Center.The patients were divided into two groups according to the pancreaticojejunostomy method:the double U-stitch 1.0 group(70 cases before modification)and the double U-stitch 2.0 group(80 cases after modification).The postoperative complications of the two groups were compared.Results The overall postoperative complications were significantly lower in the double U-stitch 2.0 group as compared with the double U-stitch 1.0 group(13.8％vs.38.6％,P=0.001).The incidence of clinically relevant pancreatic fistula was 18.6％in the double U-stitch 1.0 group,while this was significantly decreased in the double U-stitch 2.0 group(6.3％)(P=0.021).Postoperative extraluminal hemorrhage occurred in 5 patients in the double U-stitch 1.0 group,while in the double U-stitch 2.0 group,only one patient experienced postoperative intraluminal hemorrhage,the difference was statistically significant between two groups(P=0.007).The median postoperative length of hospital stay was significantly shorter in the double U-stitch 2.0 group than that in the double U-stitch 1.0 group(11d vs.14 d,P=0.001).Conclusions The modified"double U-stitch pancreaticojejunostomy"can significantly reduce the incidence of clinically relevant pancreatic fistula and other relevant severe complications,which helps improve the safety of the procedure.

Twelve compounds were isolated from the ethyl acetate fraction of the 80% aqueous ethanol extract of the roots and stems of Dalbergia rimosa Roxb. by silica gel, MCI, Sephadex LH-20 column chromatography, and semi-preparative HPLC.

Compound 1 and 2 are new compounds, and compounds 3-12 were isolated from this plant for the first time. Compounds 1, 2, 4, 6, 8, 11, 12 showed good scavenging effect on DPPH free radical.

Objective: To evaluate the incidence, treatment, and survival outcomes of Swyer syndrome with gonadal non-dysgerminoma malignant germ cell tumor (MGCT-NDG). Methods: A retrospective study was performed on Swyer syndrome patients with MGCT-NDG between January 2011 and December 2022 in Peking Union Medical College Hospital to investigate their characteristics and outcomes. Results: A total of 15 patients (4.9%, 15/307) with Swyer syndrome were identified in 307 MGCT-NDG patients. The average age at diagnosis of MGCT-NDG and Swyer syndrome were (16.8±6.7) and (16.7±6.6) years, respectively. Six cases were preoperatively diagnosed as Swyer syndrome, of which 4 cases received bilateral gonadectomy with or without hysterectomy, while the other 2 cases underwent removal of gonadal tumor and unilateral gonadectomy with hysterectomy, respectively. Of the 9 patients postoperatively diagnosed as Swyer syndrome, unilateral gonadectomy, removal of gonadal tumor, and unilateral gonadectomy with hysterectomy were performed in 6 patients, 2 patients, and 1 patient, respectively. Mixed malignant germ cell tumor (MGCT;10 cases), yolk sac tumor (4 cases), and immature teratoma (1 case) were the pathological subtypes, in the descending order. There were International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ in 6 cases, stage Ⅱ in 3 cases, stage Ⅲ in 5 cases, and stage Ⅳ in 1 case, respectively. Eleven patients received reoperation for residual gonadectomy after a average delay of (7.9±6.2) months, including 8 MGCT-NDG patients and 1 gonadoblastoma patient, no tumor involved was seen in the remaining gonads in the other 2 cases. Ten patients experienced at least one recurrence, with a median event free survival of 9 months (5, 30 months), of which 2 patients received surgery only at the time of initial treatment. All patients with recurrence received surgery and combined with postoperative chemotherapy. After a median follow-up of 25 months (15, 42 months), 10 patients were disease-free, 3 patients died of the tumor, 1 died of side effects of leukemia chemotherapy, and 1 survived with disease. Conclusion: The incidence rate of Swyer syndrome in patients with MGCT-NDG is about 4.9%; timely diagnosis and bilateral gonadectomy should be emphasized to reduce the risk of reoperation and second carcinogenesis in this population.
