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 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 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.

An online enrichment-separation system of C18 and inductively coupled plasma-mass spectrometry (ICP/MS) with flow injection (C18-FI-ICP/MS) was established for the determination of trace heavy metals in seawater. The optimized experimental parameters including pH,C18 column,concentration of methol in elute and the velocity of elute were investigated. This system was applied to the online preconcentration , separation and determination of trace heave metals in seawater samples successfully. The detection limit (3σ) for Cd, Pb, Co, Ni and Zn was 0.03, 0.09, 0.1, 0.1, 0.3 μg/L respectively. The RSD of Cd, Pb, Co, Ni, and Zn for six measurements of seawater was 6.8%,3.4%,1.3%,2.6%,0.5%,respectively. The accuracy was verified with spiked recovery test. The recovery for five elements was 91.3%,95.1%,100.4%,100.3%,95.2%, respectively.
