Objective : To explore the expression of prohibitin2(PHB2) in breast cancer and its effect on the biological behaviors of tumor cells. Methods : Immunohistochemistry was used to detect the expression of PHB2 protein in breast cancer tissues and its relationship with clinicopathologic features. Breast cancer stable transient cell lines were constructed with knockdown and overexpression ofPHB2, respectively. The effects of PHB2 on cell proliferation, migration and invasion ability were detected by clone formation assay, scratch assay and Transwell assay. Western blot(WB) was used to detect the effects of PHB2 on the expression of epithelial-mesenchymal transition(EMT)-related markers, including E-cadherin, N-cadherin, Snail family transcriptional repressor 1(Snail) protein, Vimentin, and Claudin-1. The effect of PHB2 on tumorigenicityin vivowas detected by subcutaneous tumor formation assay in nude mice. Results: The result of immunohistochemical showed that PHB2 was highly expressed in breast cancer and the expression of PHB2 was significantly positive correlated with tumor size, human epidermal growth factor receptor-2(HER-2) status and proliferation index Ki-67 levels(P<0.05). Clone formation assay, scratch assay and Transwell assay revealed that knockdown ofPBH2significantly inhibited the proliferation, migration and invasion ability of breast cancer cells(P<0.01), while the overexpression ofPHB2significantly promoted cell proliferation, migration and invasion(P<0.01). The result of subcutaneous tumor formation experiment in nude mice revealed a significant decrease in tumor volume and weight in knockdownPHB2mice(P<0.000 1), whilePHB2overexpression tumors significantly increased in volume and weight(P<0.001).WB assay showed that the protein expression of epithelial marker E-cadherin increased, while the expressions of mesenchymal markers N-cadherin, Snail and Vimentin decreased significantly afterPHB2knockdown with them in control cells(P<0.01). The expression of Claudin-1 decreased, while the expressions of N-cadherin, Snail and Vimentin increased significantly inPHB2overexpression cells(P<0.05). Conclusion PHB2 is highly expressed in breast cancer and promotes multiple malignant biological behaviors in tumor cells, suggesting PHB2 may be a potential target for breast cancer diagnosis and treatment.

Helicobacter pylori(H.pylori)infection triggers gastric mucosal inflammatory responses and spasmolytic polypeptide-expressing metaplasia(SPEM).These pathological conditions can escalate the severity of chronic gas-tritis,gastric ulcers and even cause gastric cancer.SPEM is frequently viewed as an early sign of gastric mucosal injury and the onset of carcinogenesis.A comprehensive analysis of the genesis and molecular regulation of SPEM cells in the context of H.pylori infection further has enlightened the pathogenesis of gastric mucosal diseases and provide new ideas and targets for diagnosing and treatment of H.pylori-related gastric mucosal diseases.This paper reviews a variety of molecular biomarkers associated with SPEM,encompassing TFF2,CD44v9,and AQP5,and delineates their pivotal regulatory functions in H.pylori infection and SPEM.This paper also reviews the origination of SPEM cells and pertinent molecular regulatory mechanisms.

Objective This study aims to explore the formation of the dilemma of"giving care"for disabled elderly people in nursing homes from the perspective of active health.Methods Purposive sampling was used to select caregivers and disabled elderly people from a nursing home in Chongqing as research subjects from July 2022 to December 2022.One-on-one in-depth interviews were conducted and Colaizzi's 7-step thematic analysis method was employed to collect and analyze the interview data.Results 4 themes were identified:①the dominance of the"giving"care concept,including the cultural thoughts of filial piety,passive acceptance of care characteristics and consumer psychology regarding paid services;②insufficient"participation"care ability,including lack of knowledge regarding active health and a weakening of skills to promote participation;③the hindrance to"transformation"of care models,including objective limitations in terms of human resources and delays in adapting aging environments;and ④the decline in"utilization"of internal abilities,including excessive avoidance of potential risks,a heavy workload of care and poor quality of individual care.Conclusion The formation of the dilemma of"giving care"for disabled elderly people in nursing homes is affected by multiple factors such as social background,service system,supply resources,and management mode.Transforming disabled elderly individuals from a state of"passive giving care"to"active participation in their health"is an important measure to realize the concept of positive aging and healthy aging.

This study aimed to evaluate the efficacy and safety of mycophenolate mofetil (MMF) or tacrolimus (TAC) compared with azathioprine (AZA) as maintenance therapy for active lupus nephritis (ALN). Patients with ALN who responded to 24 weeks of induction treatment were enrolled. Patients who received MMF or TAC as induction therapy continued MMF or TAC treatment during the maintenance period, whereas those who received intravenous cyclophosphamide were subjected to AZA treatment. The primary endpoint was the incidence of renal relapse. Secondary endpoints included extrarenal flares and composite endpoints (deaths, end-stage renal disease, or doubling of serum creatinine levels). A total of 123 ALN patients (47 in the MMF group, 37 in the TAC group, and 39 in the AZA group) were enrolled. The median follow-up time was 60 months. Ten MMF-treated patients, ten TAC-treated patients, and eight AZA-treated patients experienced renal relapses (P = 0.844). The cumulative renal relapse rates in the MMF group (P = 0.934) and TAC group (P = 0.673) were similar to the renal relapse rate in the AZA group. No significant difference in the incidence of severe adverse event was observed among the groups. Long-term maintenance therapies with MMF or TAC might have similarly low rates of renal relapse and similar safety profiles compared with AZA.

OBJECTIVE: To explore molecular etiology and clinical characteristics of two pedigrees affected with hereditary factor VII(FVII) deficiency. METHODS: The nine exons and flanking sequences of the F7 gene of the probands were amplified by PCR. The amplicons were analyzed by direct sequencing. Suspected mutations were subjected to SWISS-MODEL modeling and analysis of protein structure change by Pymol software and conservation of amino acids across various species. RESULTS: For proband of pedigree 1, the prothrombin time (PT), FVII activity (FVII:C) and FVII antigen (FVII:Ag) were 36.3 s, 3%, 53.56%, respectively. Sequencing revealed a compound heterozygous variants of c.80_81delCT and c.1371G>T(p.Arg439Ser). His son carried a heterozygous c.1371G>T (p.Arg439Ser) variant. For proband of pedigree 2, the PT, FVII:C and FVII:Ag were 22.3 s, 4%, 1.58%, respectively. Sequencing has revealed a compound heterozygous c.278G>T(p.Arg75Met) missense variant in exon 3 and c.1278T>G (p.His408Gln) in exon 9 of the F7 gene. His mother and son both carried a heterozygous c.278G>T(p.Arg75Met) variant. Three-dimensional simulation and homology analysis revealed that the p.Arg439Ser and p.Arg75Met can respectively alter part of hydrogen bonds and two highly conserved amino acids. CONCLUSION Two novel heterozygous missense variants of the F7 gene [c.1371G>T(p.Arg439Ser) and c.278G>T(p.Arg75Met)] probably account for the decrease of factor VII in the two pedigrees.

OBJECTIVE: To define genetic profiling of homologous recombination (HR) deficiency in Chinese ovarian cancer patients. METHODS: we have applied next-generation sequencing to detect deleterious mutations through all exons in 31 core HR genes. Paired whole blood and frozen tumor samples from 50 Chinese women diagnosed with epithelial ovarian carcinomas were tested to identify both germline and somatic variants. RESULTS: Deleterious germline HR-mutations were identified in 36% of the ovarian cancer patients. Another 5 patients had only somatic mutations. BRCA2 was most frequently mutated. Three out of the 5 somatic mutations were in RAD genes and a wider distribution of other HR genes was involved in non-serous carcinomas. BRCA1/2-mutation carriers had favorable platinum sensitivity (relative risk, 1.57, p<0.05), resulting in a 100% remission probability and survival rate. In contrast, mutations in other HR genes predicted poor prognosis. However, multivariate analysis demonstrated that platinum sensitivity and optimal cytoreduction were the independent impact factors influencing survival (hazards ratio, 0.053) and relapse (hazards ratio, 0.247), respectively. CONCLUSION: our results suggest that a more comprehensive profiling of HR defect than merely BRCA1/2 could help elucidate tumor heterogeneity and lead to better stratification of ovarian cancer patients for individualized clinical management.

OBJECTIVE: To explore the appropriate treatment of malignant germ cell tumor (MGCT) in the female genital system, and to analyze the factors influencing both therapeutic response and survival outcome. METHODS: A cohort of 230-Chinese women diagnosed with MGCT of the genital system was retrospectively reviewed and prospectively followed. The demographic and pathological features, extent of disease and surgery, treatment efficiency, recurrence and survival were analyzed. RESULTS: MGCTs from different genital origins shared a similar therapeutic strategy and response, except that all eight vaginal cases were infantile yolk sac tumors. The patients' cure rate following the initial treatment, 5-year overall survival and disease-free survival (DFS) were 85.02%, 95.00%, and 86.00%, respectively. Although more extensive excision could enhance the remission rate; it did not improve the patients' survival. Instead, the level of the medical institution, extent of surgery and disease were independent prognostic factors for relapse (p<0.05). Approximately 20% of patients had recurrent or refractory disease, more than half of whom were in remission following secondary cytoreductive surgery with salvage chemotherapy. CONCLUSION: Fertility-sparing surgery with or without standardized PEB/PVB (cisplatin, etoposide/vincristine, and bleomycin) chemotherapy is applicable for female MGCTs of different origins. Comprehensive staging is not required; nor is excessive debulking suggested. Appropriate cytoreduction by surgery and antineoplastic medicine at an experienced medical institution can bring about an excellent prognosis for these patients.

ObjectiveToinvestigate the prevalence, awareness and risk factors of chronic kidney disease (CKD) among community adult population in Shanghai, China, in order to provide early diagnosis and treatment of CKD, and informations for national health policy makers.MethodsTwo thousand five hundred and ninety six residents (≥ 18 years old) were randomly selected from community population in Changning district of Shanghai, China. They were interviewed and tested for albuminuria -morning spot urine albumin to creatinine ratio [ACR, abnormal: ≥ 17 mg/g (male), ≥25 mg/g (female)], reduced renal function-estimated GFR by abbreviated MDRD equation [abnormal: <60 ml ·rain-1 (1.73 m2)-1] and hematuria-morning spot urine dipstick confirmed by urine microscopy. The associations among demographic characteristics, healthy characteristics (e.g. diabetes and hypertension) and indicators of kidney damage were examined. The investigators and neighborhood committee were well trained. Those who had semiquantitative positive were detected again by albuminuria-morniag spot urine albumin to creatinine ratio after three months. ResultsTwo thousand five hundred and fifty four residents with complete data were enrolled in the study. Albuminuria was detected in 6.3% of subjects, reduced renal function in 5.8%, hematuria in 1.2%. Approximately 11.8% of these subjects had at least one indicator of kidney damage. The awareness rate of CKD was 8.2%. The Logistic regression model showed that hyperuricemia, nephrolithiasis, anemia, diabetes, central obesity, hypertension and age contributed to the development of CKD. ConclusionsThe prevalence of CKD in community adult population in Shanghai is 11.8%, And the awareness rate of CKD is 8.2%. Hyperuricemia, nephrolithiasis, anemia, diabetes, central obesity, hypertension and age are risk factors of CKD.

OBJECTIVE:To observe the effects of matrine in conjunction with vincristine(VCR),adriamycin(ADM)and diamminedichloroplatinum(DDP),respectively on the cell cycle of the KBV200drug-resistant cell line.METHODS:The cultured KBV drug-resistant cells were divided into control group,antitumor drug groups and the combination therapy groups(marine+antitumor drugs,respectively),FCM assay was used to detect and analyze the expression of cell cycle and apoptosis of each group.RESULTS:As compared with single antitumor drugs groups,no significant change was found in the proportion of cells and cell apoptosis in the combination therapy groups(matrine+VCR or matrine+ADM).But marine+DDD resulted in a reduction of the G 0 ～G 1 stage cell population but an increase of G 2 ～M stage cell population.CONCLUSIONS:It was assumed that matrine-induced reversal of KBV200cells'drug-resistant to VCR and ADM may not relate to cell cycle and cell apoptosis.Matrine can slightly enhance the cytotoxic effect of DDP.
