Objective: To evaluate the prognostic factors of patients with stage Ⅳ gastric cancer. Meth-ods: A total of 138 patients with stage Ⅳ gastric cancer treated with platinum-based chemotherapy were ana-lyzed. Survival rate was estimated by Kaplan-Meier method. The prognostic factors were analyzed by univari-ate (Log rank) and multivariate (Cox model) analysis methods. Results: Univariate analysis and multivariate analysis showed that poor performance status (P=0.001), weight loss (P=0.001), depth of invasion (P=0.000), presence of peritoneal metastasis (P=0.005), more than 1 metastatic site (P=0.029) and elevated total biliru-bin (P=0.018) were independent prognostic factors. According to the outcomes of the Cox model analysis, a formula of the prognostic index was developed. According to the values of PI, 16 patients were categorized as the high-risk group (PI≤9.817), 28 patients were categorized as the moderate-risk group (9.817

Objective To assess the prevalence of gastroesophageal reflux disease(GERD) in the population of Fujian province, and to analyze the risk factors in relation to the disease. Methods A survey on GERD symptoms and its related factors was carried out in the population of Fuzhou city in Fujian province using a stratified random sampling method. According to reflux disease questionnaire (RDQ) score, the subjects were divided to GERD group with Sc≥ 12 and control group with Sc＜ 12.The risk factors related to GERD were compared between two groups. Results A total of 1347residents were investigated. The prevalence of GERD was 8.76 %, and male to female ratio wasincreased in population above 40 years of age (P＜0.05). The incidence of GERD in subjects with different occupations was as follows: the businessmen [17.91%(12/67)], retirees [13.48%(12/89)]and soldiers [2.94%(2/68)]. Symptoms including abdominal distension, belching, nausea, vomiting,dyspepsia were common in GERD group compared to control group (P ＜ 0.01). Besides, the laryngitis, pharyngitis and mouth ulcer were common in GERD group compared to control group ( P＜0.05). The risk factors of GERD were eating greasy (OR= 1.589) and sweetmeat (OR= 2.413),overeating (OR = 2.053), constipation (OR = 1.650), acridity food (OR = 1.366 ), coffee (OR =1.295), strong tea (OR= 1.362). Conclusions The prevalence of GERD is high in the population of Fujian province, and many factors are closely related to reflux.

Objective To assess the prevalence and related factors of gastroesophageal reflux disease (GERD) in troops stationed in southern China. Methods An investigation with validated questionnaire and stratified random sampling method was carried out in troops stationed in southern China to survey the prevalence of GERD and its related factors. According to the definition of reflux disease questionnaire (RDQ) score,the severity and frequency of the dominant symptoms of GERD,such as heartburn,acid regurgitation,food reflux and non-cardiogenic chest pain were scored. People with score equaled to and higher than 12 (Sc≥12) were assigned to patient group,and those with score lower than 12 (Sc0.05). Subjects in the patient group had a higher incidence of abdominal distension,belching,nausea,vomiting,abdominal pain compared with control group. A higher incidence of laryngitis,pharyngitis and ulcerative stomatitis (P

Acute promyelocytic leukemia (APL) is a special subtype of acute myeloid leukemia, characterized by the reciprocal chromosomal translocation of t (15;17)(q22;q21), which generates PML-RARαfusion protein. All-trans-retinoic acid (ATRA) and As2O3 could induce APL cells to differentiation and apoptosis, respectively, making APL become the first curable leukemia. Autophagy is one of metabolic mechanisms to maintain cell homeostasis. Recent studies have showed that autophagy plays an important role in the differentiation of APL cells induced by ATRA/As2O3. Meanwhile, autophagy may affect the sensitivity of APL cells to the pro-apoptotic effect of drugs. Therefore, targeting and regulating autophagy might be a new therapeutic approach of APL and even other leukemia in the future. This article will briefly review the advance of autophagy in APL in recent years.

The metabolic characteristics of ligustrazin (TMPz) in liver microsomes were investigated in the present study. The reaction phenotyping of TMPz metabolism was also identified by in vitro assessment using recombinant human cytochrome P450 enzymes (CYP) and UDP glucuronosyltransferases (UGT). TMPz was incubated at 37 degrees C with human (HLM) and rat liver microsomes (RLM) in the presence of different co-factors. The metabolic stability and enzyme kinetics of TMPz were studied by determining its remaining concentrations with a LC-MS/MS method. TMPz was only metabolically eliminated in the microsomes with NADPH or NADPH+UDPGA. In the HLM and RLM with NADPH+UDPGA, t1/2, K(m) and V(max) of TMPz were 94.24 +/- 4.53 and 105.07 +/- 9.44 min, 22.74 +/- 1.89 and 33.09 +/- 2.74 micromol x L(-1), 253.50 +/- 10.06 and 190.40 +/- 8.35 nmol x min(-1) x mg(-1) (protein), respectively. TMPz showed a slightly higher metabolic rate in HLM than that in RLM. Its primary oxidative metabolites, 2-hydroxymethyl-3, 5, 6-trimethylpyrazine (HTMP), could undergo glucuronide conjugation. The CYP reaction phenotyping of TMPz metabolism was identified using a panel of recombinant CYP isoforms (rCYP) and specific CYP inhibitors in HLM. CYP1A2, 2C9 and 3A4 were found to be the major CYP isoforms involved in TMPz metabolism. Their individual contributions were assessed b) using the method of the total normalized rate to be 19.32%, 27.79% and 52.90%, respectively. It was observed that these CYP isoforms mediated the formation of HTMP in rCYP incubation. The UGT reaction phenotyping of HTMP glucuronidation was also investigated preliminarily by using a panel of 6 UGT isoforms (rUGT). UGT1A1, 1A4 and 1A6 were the predominant isoforms mediated the HTMP glucuronidation. The results above indicate that the metabolism of TMPz involves multiple enzymes mediated phase I and phase II reactions.

Objective To investigate the multiple risk factors for lower extremity lymphedema in patients following treatment of common gynecologic cancers by meta-analysis for systematic analysis and comprehensive quantitative study.Methods Clinical trials published up until August 2016 were retrieved from PubMed, Embase, and the Cochrane Library.The quality of the included studies was assessed by the Newcastle-Ottawa Scale, and data analysis was performed using Stata 14.0 and RevMan 5.3.The strength of the associations between risk factors and gynecologic cancer-related lower extremity lymphedema was described as odds ratio (OR) and 95% confidence intervals (CI).Results Eighteen studies were included in the meta-analysis, and 8 relevant factors were identified.The risk factors for lower extremity lymphedema after treatment of gynecologic cancer mainly included radiotherapy (OR=2.45, 95%CI:2.05-2.95, P=0.000), FIGO stage (OR=2.29, 95%CI:1.66-3.14, P=0.000), and pelvic lymph node dissection (OR=2.00, 95%CI:1.02-3.91, P=0.040).Conclusions Radiotherapy, FIGO stage, and pelvic lymph node dissection are the main risk factors for lower extremity lymphedema after treatment of gynecologic cancers.

AIM: To investigate the effect of flavone on oxidation-induced injury in retinal pigment epithelium(RPE) cells. METHODS: In in vivo studies, NaIO3-induced RPE degeneration in rat eyes were treated with 5g/L flavone eye drops 3 times a day for 1 week before and 4 weeks after NaIO3injection. At the end of 2 and 4 weeks, all rats were measured c-wave by electroretinogram(ERG). In in vitro studies,ARPE-19 cells were treated with hypoxia, H2O2, NaN3and t-BHP to induce cell damages. MTT assay was used to measure the viable cells. RESULTS: The ERG c-wave results showed that flavone reversed NaIO3-induced injury at the end of 4 weeks. In vitro results showed flavone reversed the various oxidants-induced injuries in RPE cells.CONCLUSION: Flavone could prevent the RPE from oxidation-induced injury both in vivo and in vitro.
