Objective To compare the predictive power of model for end-stage liver disease(MELD) and Child-Turcotte-Pugh(CTP) on the cirrhotic patients who underwent transjugular intrahepatic portosystemic shunt(TIPS).Methods A total of 110 patients(98 males and 12 females) undergoing TIPS from January 2004 to March 2008 in our hospital were analyzed.Data of all patients were analyzed retrospectively.The main statistical tests included: Kaplan-Merier analysis to compare survival respectively,and the area of receiver operating characteristics(ROC) to compare the performance of the 2 models for predicting 3-month,1-year,and 2-year mortality.Results The survival rate rate of the patients whose MELD score under 15 showed significantly higher than the patients above MELD score 15.The area of ROC that predicting survival was 0.866 and 0.863 at 3 months,0.755 and 0.739 at 1-year,0.729 and 0.750 at 2-years respectively for the MELD and the CTP score.Conclusion Both MELD and CTP score can predict short-term survival accuracy,but poor in long-term.However,the MELD has overcome the shortcomings of CTP,and may be worth using in clinical.

BACKGROUND: Microsatellite instability (MSI), an important gene change type, plays animportant role in the occurrence of tumor. Mismatch repair gene induces its occurrence. Although the effect of mismatch repair gene hMLH1 mutation in the hereditary nonpolyposis colorectal cancers (HNPCC) has been reported, its effect on the sporadic colorectal carcinoma lacks in-depth study.OBJECTIVE: To investigate the effect of mismatch repair gene hMLH1 mutation on colorectal carcinogenesis, and its correlation with MSI.DESIGN: Single-sample experiment.SETTING: Department of Gastroenterology, Southwest Hospital of Third Military Medical University of Chinese PLA.PARTICIPANTS: Seventy-six cases of sporadic colorectal carcinoma and corresponding normal tissues were obtained from surgically resected specimens of coloreetal carcinoma in Southwest Hospital between January 2001and December 2003. No patients had family history of tumor, or had received radiotherapy and chemotherapy. Patients were informed of the experiment.METHODS: Mutation of hMLH1 was detected by two-dimensional electrophoresis and DNA sequencing; MSI was analyzed by PCR-based methods.MAIN OUTCOME MEASURES: ① Detection rate of hMLH1 mutation of colorectal carcinoma and MSI. ② The relationship of MSI and hMLH1 mutation.RESULTS: Seventy-six cases of sporadic colorectal carcinoma were studied for hMLH1 mutation and MSI. hMLH1 mutation was detected in 8 (10.5%) cases of colorectal carcinomas while MSI was detected in 20 (26.3%) cases of colorectal carcinomas. Frequency of hMLH1 mutation and MSI was significantly higher in right colorectal cancer than in left colorec tal cancer (6/26 vs 2/50, x2=4.739, P=0.029; 11/26 vs 9/50,x2=5.212,P=0.022). No association was observed between hMLH1 mutation or MSI and tumor size, differentiation, histological type, depth of invasion, metastasis or clinical pathological stages. ② MSI was divided into high-frequency group (≥ 2 loci, n=10) and low-frequency group (1 locus, n-10), and MSI negative group (n=56). 8 hMLH1 mutations were all detected in high frequency MSI group, but no mutation was found in low frequency MSI or MSI negative groups.CONCLUSION: hMLH1 mutation and MSI occur in cancer of the right large intestine and hMLH1 mutation is involved in carcinogenesis of some sporadic colorectal cancer with high-frequency MSI.

Objective To investigate the pathological and immunohistochemical characteristics of female bladder ectopic skene glands.Methods A female with bladder tumor was treated in our hospital in May 2013.Preoperative so(n)graphy revealed a 0.9 cm×0.6 cm round solid mass in the bottom of bladder wall.Mass was hypoechoic homogeneous with regular shape,blood flow within the mass was noted.The tumor was treated with transurethral resection.Routine pathological examination suggested bladder ectopic Skene glands.Immunohistochemical stains for prostate specific antigen (PSA),prostate spectific acid phosphatase (PSAP),androgen receptor (AR),estrogen receptor (ER),CD10,cytokeratin 14 (CK14),cytokeratin 18 (CK18),P63,high molecular weight cytokeratin (34βE12),α-methylacyl-CoA racemase (AMACR/p504s) were further performed.Results Routine pathological examination showed prostate glands composed of prostate gland epithelial cells and basal cells in a submucosal location.Immunohistochemical stains showed:PSA-,PSAP +,AR +,ER-,CD10+,CK18 +,CK14-,P63 +,34βE12 +,AMACR-.Conclusions Routine pathological examination combined with immunohistochemical stains such as PSA,PSAP,and others,can be used to diagnose ectopic Skene glands disease.Female bladder ectopic Skene glands is a benign lesion,and the prognosis is good.

Objective To investigate the current situation of long-term care needs of the elderly with home-based disabil-ity in Beiliu City,and provide data support for the development of Internet plus care services in Beiliu City.Methods A ques-tionnaire survey method was used to design and distribute a survey questionnaire titled"Survey Questionnaire on Home Care Serv-ice Needs of Disabled Elderly People",to investigate the nursing service methods and home care needs of disabled elderly people in Beiliu City.Results Disabled elderly people mainly choose home-based nursing services,with a high demand for basic care,comfortable care,rehabilitation care,psychological care,and other aspects.Conclusion Home care is of great significance for improving the quality of life of disabled elderly people,and requires policy support such as medical insurance to promote the sup-ply of nursing services and meet the care needs of disabled elderly people.

Objective: To explore the gene lifestyle interaction of ATP2B1-eNOS pathway gene polymorphisms on blood pressure. Methods: Using the convenient cluster sampling method, a total of 872 junior middle school students from 3 school in July to August 2019, were included in the final analysis. The survey included questionnaire investigation, anthropometry measurement and blood sample collection. After DNA was extracted from peripheral blood samples, the gene polymorphisms ( ATP2B1 gene rs 17249754 and rs 2070759, eNOS gene rs 1799983 and rs 2070744) were genotyped. Logistic regression model was used to analyze the association between gene polymorphism and blood pressure phenotypes. Results: The prevalence of high blood pressure was 9.52 % in adolescents(9.15% in boys and 9.87% in girls),with no significant sex difference ( χ 2=0.13, P =0.72). There were statistically significant differences between boys and girls in age, systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI) classification, birth weight, daily school physical exercise time and daily playing video games time ( P <0.05). Logistic regression analysis showed that, eNOS gene rs 2070744 polymorphism was associated with high blood pressure (HBP) under the recessive model, and the risk of HBP in CC genotype carriers were higher than that TT/TC genotype carriers ( OR=3.88, 95%CI =1.00-15.02, P < 0.05 ). The results of gene lifestyle interaction showed that ATP2B1 gene rs 2070759 polymorphism gene had an interaction with the time of physical exercise in school ( P interaction =0.05). In the subgroup with daily physical exercise time at sch ool ＜1 hour , the TT/TG genotype carriers were associated with increased risk of HBP compared with GG genotype carriers( OR= 2.65 , 95%CI =1.11-6.30, P <0.05). But in the subgroup with daily physical exercise time in school ≥1 hour, rs 2070759 was not significantly associated with HBP. Conclusion eNOS/rs 2070744 polymorphisms are associated with risk of HBP among adolescents. There is significant interaction between ATP2B1 gene rs 2070759 polymorphism and physical exercise time in school on HBP. Adolescents should spend more time on physical activity in school, which will help to maintain normal blood pressure level.
