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.

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.

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.

Objective To examine the correlation between metabolic acidosis and malnutrition in maintenance haemodialysis (MHD) patients. Methods Forty-four MHD patients were divided into 3 groups according to plasma bicarbonate concentrations (PHCO3) and pH values. The correlation between metabolic acidosis and nutritional parameters was studied. Results The mean PHCO3 was (19.1?0.9) mmol/L in group A (n=13), (24.0?1.3) mmol/L in group B (n=22) and (27.1?0.1) mmol/L in group C (n=9). The adequacy of dialysis (Kt/V) was comparable in three groups. As compared with group B, group A had significantly higher body mass index (BMI), triceps skin fold thickness (TSF), dietary protein intake (DPI), normalized protein catabolic rate (nPCR) , Scr, serum K+ and parathyroid hormone (PTH), meanwhile, group C had significantly lower DPI, nPCR, Scr and albumin. There was no significant difference in plasma inflammatory markers C-reactive protein (CRP) among three groups. There was significant negative correlation of PHCO3 to nPCR (P

We studied the regulatory effects of the estragen receptorbeta (ERbeta) gene on the downstream estrogen signal transfection pathway in colon cancer cells and the possible mechanisms involved. A human ERbeta gene recombinant expression plasmid, pEGFP-C1-ERbeta, was constructed and transfected into the Caco-2 colon cancer cell line, a line with low ERbeta gene expression. The expression of ERbeta mRNA and protein was detected 72 h after transfection. RT-PCR was used to examine the expression levels of the progesterone recepror (PR) gene containing the classic estrogen response element (ERE), the C-fos oncogene containing the AP-1 site (a non-classical ER binding site), the epigenetic modifying genes, such as Dnmt1, Dnmt3a, Dnmt3b, and histone methyltransferase (HMT), and the human mismatch repair gene hMLH1. Methylation-specific PCR was used to detect the changes in the methylated sites of the CpG islands in the promoters of the ERbeta, PR, and C-fos genes. The results indicated that the human ERbeta gene recombinant expression plasmid pEGFP-C1-ERbeta was successfully constructed and transfected into Caco-2 cells. As compared with the control group, the mRNA and protein expression of ERbeta gene was increased significantly 72 h after the transfection of pEGFP-C1-ERbeta into the Caco-2 cells. As compared with the control group, the mRNA expression of the PR, C-fos, Dnmt3a and Dnmt3b genes was increased significantly 72 h after the transfection of pEGFP-C1-ERbeta into the Caco-2 cells, but the mRNA expression of the Dnmt1, HMT, and hMLH1 genes decreased significantly (P<0.05). As compared with the control group, different degrees of demethylation occurred in the promoters of the ERbeta, progesterone receptor (PR), and C-fos oncogene 72 h after the transfection of pEGFP-C1-ERbeta into the Caco-2 cells. The methylation index of the estrogen signal transfection pathway in Caco-2 cells was decreased significantly following the expression restoration of ERbeta gene (P<0.05). It is concluded that the restoration or up-regulation of the ERbeta gene in Caco-2 cells may significantly activate the expression of the related target genes in the downstream estrogen signal transfection pathway and may result in the demethylation changes of the pathway. During the process, the expression level and activity of the epigenetic modifying genes and the human mismatch repair gene have changed simultaneously. The regulatory effect of the ERbeta gene on the estrogen signal transfection pathway to a certain extent partly involves demethylation.

Objective To detect the expression and function of cysteinyl leukotriene receptors (CysLTRs)in keratinocytes.Methods Human keratinocytes were isolated from the tissue of foreskin by digestion with dispase Ⅱ and trypsin,and subjected to primary culture.By using confocal laser scanning microscopy and reverse transcriptase PCR,the localization and expression of CysLTRs were studied in kemtinocytes.respectively.Some primarily cultured keratinocytes were pretreated with leukotriene D4 (30 nmoi/L),MK571(300 nmol/L),and BAYu9773 for 5 minutes followed by the detection of intmcellular calcium level using the Ca2+ indicator dye Fura-2/AM as well as cell proliferation bv MTT assay.Results The expressions of CysLTR1 and CysLTR2 were observed in cultured keratinocytes,and they were mainly located on cell membrane,partly in cytoplasm and nuclei.Compared with non.stimulated cells,a significant increase Was noted in the expression of CysLTRs,especially in the nuclei of keratinocytes stimulated by LTD4(P＜0.05),together with an elevation in intracellular calcium level(42.27±3.00 mmol/L,P＜0.01)and acceleration in cell proliferation (P＜0.01).However,both MK571 and BAYu9773 could completely block the effect of LTD4 on intmcellular calcium level and cell proliferation.and there was no significant difference in the blocking effect between MK571 and BAYu9773.Conclusions Functional CysLTRs are expressed in human keratinocytes.and they carl increase the intracellular calcium level in,and cell proliferation of,keratinocytes.
