Genotypes of estrogen receptor gene (ER) α and β in 110 patients with non-alcoholic fatty liver disease (NAFLD) and 100 control subjects were examined by polymerase chain reaction-based restriction fragment length polymorphism.The haplotype analysis was conducted by SHEsis on-line computing platform.The results showed that there were no differences in the genotype frequencies and allele frequencies of ERα at Xba Ⅰ and Pvu Ⅱ enzyme cutting sites between two groups (P > 0.05).There existed significant differences in the genotype frequencies and allele frequencies of ERβ at Rsa Ⅰ and Alu Ⅰ enzyme cutting sites between these two groups (P < 0.05 or P <0.01).The risk of NAFLD in postmenopausal women with R or a allele was 1.833 (95% CI1.209-2.779,P<0.05)or 1.782 (95% CI 1.037-3.061,P<0.05) fold of that with allele r or A.The frequency of r-A haplotype in ERβ was significantly lower in NAFLD group than that in control group (OR =0.529,95% CI 0.348-0.805).Logistic regression analysis showed the relationship of fasting blood glucose,triglyceride,body mass index,diastolic pressure,Alu Ⅰ genotype with NAFLD (all P<0.01).The risk of NAFLD in postmenopausal women with Aa/aa genotype was 1.345 (95% CI 1.028-2.505,P<0.05) folds of that with AA genotype.

The cultural development needs of contemporary college students generally are displayed as varied contents,rich types and distinctive characteristics.Students in military medical universities shoulder the responsibilities of both soldiers and medical students,their cultural development needs are often in contradiction to military culture,thus bringing challenges to the culture construction in military medical universities.By introducing activities from civilians and soldiers,constructing hidden cultural platforms,improving hardware facilities and other innovative methods,we can actively guide students' ideological direction and play a better culturally educational function of military schools.

Objective To evaluate the appropriateness of hospitalization days at a tertiary hospital in 2014 by means of the Appropriateness Evaluation Protocol ( AEP ) , and to analyze the causes of inappropriate stays. Methods Medical records of inpatients admitted at a tertiary hospital in 2014 were randomly selected. AEP( US version) was used to evaluate the appropriateness of every hospitalization day, while the causes of inappropriate hospitalization day were also analyzed. Results A total of 1 641 days of stay from 148 medical records were reviewed, and 129 days of stay (7. 9%) were seen as inappropriate. Two major factors for inappropriate stays were waiting for surgery and waiting for test, roughly 89. 1% of the inappropriate hospitalization days. The proportion of inappropriate hospital stays reduced to 4. 8% after adjustment of two-day weekend. Inappropriate hospital stays mostly appeared during the second day to the eighth day after admission(93. 8%). Logistic analysis results showed that with concomitant symptoms, preoperative waiting days > 5 days, high level surgery, non-emergency admission were significantly associated with appropriateness of hospital stays (P<0. 05). Conclusions The rate of inappropriate stays will be reduced and the quality of medical services will be improved if comprehensive measures could be carried out according to the causes of inappropriate stays.

Objective To study the clinical characteristics, treatment methods and prognosis of primary gastrointestinal diffuse large B-cell lymphoma (PGI-DLBCL). Methods The clinical data of 40 patients with PGI- DLBCL were retrospectively analyzed. All the cases had received surgery treatment. Results In 40 patients with PGI-DLBCL, the major clinical presentation included abdominal pain in 15 cases (37.5%), abdominal mass in 6 cases (15.0%), abdominal discomfort in 5 cases (12.5%), abdominal distension in 5 cases (12.5%), and hematemesis in 5 cases (12.5%). Fifteen cases were misdiagnosed as gastric cancer, 5 cases as colon cancer, and 4 cases as digestive tract ulcer. The misdiagnosis rate was 60.0% (24/40). The survival rates of 1- , 2- and 3- year were 62.3%, 57.5% and 52.6%. The univariate analyses result showed that the clinical stage, international prognosis index (IPI) and treatment method were associated with survival rate (P<0.01), but the gender, age and disease distribution were not associated with survival rate (P > 0.05). The 3-year survival rate of clinical stage Ⅰ - Ⅱ was significantly higher than clinical stageⅢ-Ⅳ(68.0%vs. 13.3%), the 3-year survival rate of IPI 0-2 scores was significantly higher than 3 - 5 scores (66.7% vs. 7.6%), and the 3- year survival rate of surgery combined with postoperative chemotherapy was significantly higher than simple surgery (75.0%vs. 20.0%), there were statistical differences (P<0.01). Conclusions The patients with PGI- DLBCL have no obvious clinical manifestions and a higher misdiagnosed rate. Modified IPI, clinical stage and surgery combined with postoperative chemotherapy are the influencing factors of prognosis.

OBJECTIVETo observe the effects of qingchang huashi recipe (QHR) on the dendritic cells (DCs) of experimental colitis rats, thus exploring its possible mechanisms for treating ulcerative colitis (UC).
METHODSThe UC rat model was induced by TNBS/anhydrous alcohol. Forty male Wistar rats were randomly divided into 4 groups, i.e., the normal group, the model group, the QHR group, and the Mesalazine group, 10 in each group. Since the 2nd day of modeling, corresponding medication was respectively administered to each treatment group by gastrogavage for 10 successive days. The number of DCs in the colonic mucosa was observed using iMmunohistochemical assay. The DCs ratio in the mesenteric lymph nodes, and the expressions of surface molecules MHC-II and CD86 were detected using flow cytometry.
RESULTSCompared with the model group, the number of DCs in the colonic mucosa significantly decreased, the expression of MHC-II in the mesenteric lymph nodes significantly decreased in the QHR group and the Mesalazine group, showing statistical difference (P < 0.01). There was no statistical difference between the two groups (P > 0.05). There was no statistical difference in the DCs ratios and the CD86 expression among the 4 groups (P > 0.05).
CONCLUSIONQHR could decrease the infiltration of DCs in the colonic mucosa, and suppress the activation of DCs in the mesenteric lymph nodes, which might be one of its mechanisms for treating UC.
