BACKGROUND:Tumor stem cels have self-renewal, drug resistance and metastasis tumorigenicity, which play an important role in occurrence, development and metastasis of tumors. Currently, there are two methods to identify tumor stem cels, namely, in vitro tumor sphere culture experiments and in vivo mouse tumorigenic experiments. However, there ia a lack of reports regarding clinicaly enriched gastric cancer cels by chemotherapy. OBJECTIVE:To investigate the enrichment of rat gastric cancer stem cels by cisplatin, and to explore the screening methods for their surface marker proteins. METHODS: BCG-823 gastric cancer model was established in rats, and then rat models were randomized into two groups: rats in experimental groups were subjected to intravenous injection of 0.1, 0.2, 0.25, 0.3 g/L cisplatin via the tail vein; those in control group were injected with normal salinevia the tail vein. After three courses of chemotherapy, gastric stem cels-enriched tissues were colected. Tumor surface proteins were extracted using high-throughput protein microarray and identified by western blot assay. Effects of cisplatin on enrichment of rat gastric cancer stem cels and screening methods for surface marker proteins were compared. RESULTS AND CONCLUSION:Cisplatin at a dose of 0.3 g/L×200μL exhibited the best therapeutic effects, and moreover, with the dose increasing, the tolerance became worse and the incidence of adverse reaction became higher. Transplantation tumors were verified by hematoxylin-eosin staining. Western blot test results were similar to the findings of protein microarray method, that is, HLA-DQ, PMP22 and Claudin7 protein expressions increased in gastric tissues, but HLA-DR, CD14, CD16 and CD56 protein expression decreased. These findings suggest that cisplatin can be used to enrich gastric cancer stem cels in rats, and to successfuly screen the corresponding surface marker proteins.

Objective To investigate the influence of antiepileptic drugs (AEDs) on levels of serum homocysteine (Hcy),folate,vitamin B12 and B6 in patients with post-stroke epilepsy (PSE).Methods The serum levels of Hcy,folate,vitamin B12 and B6 of 194 PSE patients with AEDs treatment for more than 1 year (AEDs treatment group) and 40 newly diagnosed PSE patients without AEDs therapy (control group) were detected.The effects of AEDs on above indexes were analyzed.Results Compared with control group,the serum level of serum Hcy was significantly increased,and the serum levels of folate,B12 were significantly decreased in AEDs treatment group (all P<0.05).The difference of the serum levels of vitamin B6 among the groups was not significant.Compared with monothetapy subgroup,the serum levels of Hcy was significantly increased in the combination therapy subgroup (P<0.05).Compared with control group,the serum levels of Hcy were significantly increased in patients with Valproate (VPA),Carbamazepine (CBZ) and Oxcarbazepine (OXC) monotherapy,the serum levels of folate were significantly decreased in patients with VPA and CBZ monotherapy,and the serum level of B12 was significantly decreased in patients with VPA monotherapy (all P<0.05).Compared with control group,the serum levels of Hcy were significantly increased in patients with 2 kinds of AEDs combination treatment [VPA+CBZ,VPA+Levetiracetam (LEV),VPA+OXC,CBZ+LEV] or ≥3 kinds of AEDs combination treatment,the serum levels of folate was significantly decreased in patients with 2 kinds of AEDs combination treatment (VPA+LEV,VPA+OXC,CBZ+LEV) or ≥3 kinds of AEDs combination treatment,the serum levels of B12 were siginificantly decreased in patients with 2 kinds of AEDs combination treatment (VPA+CBZ,VPA+OXC,CBZ+LEV) or ≥3 kinds of AEDs combination treatment (all P<0.05).The incidence of hyperhomocysteinemia (HHcy) in AEDs treatment group (36.6%) was significantly higher than that in control group (20.0%) (χ2=4.085,P=0.043).And the difference of HHcy incidence between the combination therapy subgroup (47.6%) and the control group was statistical significant (χ2=6.950,P=0.008).The difference of HHcy incidence between the monotherapy subgroup (33.6%) and the control group was not significant.The HHcy incidence of patients with VPA and CBZ monotherapy (40.5%;43.8%) were significantly higer than those in the control group (χ2=3.871,P=0.049;χ2=4.726,P=0.030).The differences of HHcy incidence between patients with OXC,LEV monotherapy (29.2%;22.9%) and the control group were not significant.Conclusions AEDs therapy has little influence on the serum levels of vitamin B6,while has great influence on the serum levels of Hcy,folate and vitamin B12.Combination treatment of AEDs and monotherapy of VPA,CBZ may increase the incidence of HHcy in PSE patients.

OBJECTIVETo develop a life quality scale suitable for idiopathic pulmonary fibrosis (IPF) patients, objectively reflecting its changes.

METHODSAuthors first put forward a theoretical structure model of a scale according to patient-reported outcome (PRO) scale formulation principle by combining basic theories of Chinese medicine (CM). Then authors developed an initial scale on the basis of various life quality scales for respiratory disease patients by using structural decision making. Totally 34 patients with confirmed diagnosis of IPF were tested by questionnaire. Items were screened using expert importance scoring method, factor analysis, correlation coefficient method, Cronbach's alpha coefficient method. IPF patient reported outcomes (IPF PRO, IP) were finally defined.

RESULTSA new IP scale was developed covering three areas and 38 items. Pearson correlation coefficient for correlation analysis of clinical symptom scores in ST-George Respiratory Questionnaire and IP scale was 0.828 (P < 0.01). Pearson correlation coefficient for correlation analysis of activity ability scores was 0.929 (P < 0.01). Pearson correlation coefficient for correlation analysis of total scores was 0.862 (P < 0.01). By reliability of IP scale itself (reliability) analysis, Cronbach's alpha coefficient was 0.713. By using factor analysis method for data analysis, KMO statistics was 0.902.

CONCLUSIONIP scale fully reflected the connotation of IPF patients' quality of life, so it could be used as CM clinical therapeutic effect evaluation tool.

The association of serum nesfatin-1 levels with insulin resistance and pancreatic β-cell function in gestational diabetes mellitus was investigated.Oral glucose tolerance test(OGTT) was performed in ninety pregnant women from 24,to 28 gestational weeks.They were divided into three groups according to OGTT:45 nomal controls,27 gestational diabetes mellitus with fasting plasma glucose (FPG) of 5.1 mmol/L to 7.0 mmol/L (GDM1),18 gestational diabetes mellitus with FPG more than 7.0 mmol/L (GDM2).Serum nesfatin-1 levels were significantly higher in patients with GDM1 and GDM2 than in controls (P＜0.01),and in GDM2 group it was also higher than GDM1 group(P＜0.05).Fasting serum nesfatin-1 was positively correlated with FPG,30 min plasma glucose,1 h plasma glucose,2 h plasma glucose,homeostasis model assessment for insulin resistance,and PGAUC,but negatively correlated with homeostasis model assessment for β-cell function.Furthermore,multiple stepwise regression analysis showed that FPG was the independent influencing factor of serum nesfatin-1 level.Nesfatin-1 was positively correlated with insulin resistance,while negatively correlated with pancreatic β-cell function.Nesfatin-1 may play a role in the pathogenesis of gestational diabetes mellitus.

Objective To compare the high risk factors, complications, treatment and prognosis of respiratory distress syndrome (NRDS) in neonates at different gestational age (GA). Methods Between August 2012 and July 2013, 156 neonates with RDS were selected and distributed into 3 groups, 42 early preterm (GA<34weeks), 52 late preterm (GA 35 to 36 weeks), and 62 in term group (GA≥37 weeks). Retrospectively analysis was performed for high risk factors, complications, treatment and prognosis of the three groups. Results In 156 neonates with RDS, the male and female proportion was 2.25:1. All groups had more males, but the gender difference has no statistical signiifcance in three groups (P=0.923). The onset time of RDS and the hospitalization time both show an increasing trend of statistical signiifcance (P<0.05). Comparing the difference of high risk factors for RDS of the 3 groups, birth asphyxia, placental abnormalities, multiple pregnancy, premature rupture of membranes was most common in early preterm group, and followed by late preterm group, and C-section was most common in term group and unexplained preterm was more common in early preterm group than that in late preterm group (all P<0.05). Among the three groups, the ratio of pulmonary surfactant application was the lowest in the term group, the ratio of X-ray grade over II was high-est in early preterm group, oxygen and hospitalization time were the longest in early preterm group (P<0.05). The risks of com-plicated with pulmonary infection, intracranial hemorrhages and bronchopulmonary dysplasia were the highest in early preterm group and the risk of complicated pneumothorax was the highest in term group. Among three groups, the recovery rate was the lowest in the early preterm group (P<0.01). Conclusion The clinical characteristics, high risk factors, complications and treat-ment responses of RDS in neonates with different GA were different, so GA should be considered for diagnose and treatment. For the term infants, the elective caesarean section should be strictly controlled, in order to reduce the incidence of RDS.

Objective: By taking the holism and differentiation concepts of traditional Chinese medicine (TCM) as the guidance, physical, mental and workplace factors were recruited in the observation of depression in employees, and were systematically classified to establish a workplace-related Liver Meridian-depression scale, for providing an evaluation index for depression in employees. Methods: NVIVO 11 software was adopted to assort ancient TCM classics. Based on the holism and differentiation concepts of TCM and well-developed scales, the item pool was determined via brain storm and screened by Delphi method after classified; a Wechat questionnaire was handed out 240 times via the online system 'Wen Juan Xing', and the results were statistically analyzed by the SPSS 17.0 version software. Results: Five dimensions consisting of 80 items were obtained after classification, and 60 items were selected by Delphi method; a total of 216 questionnaires were returned and the return rate was 90%. Of which, 215 questionnaires were valid ones, and the valid rate was 99%. By exploratory factor analysis (EFA), 44 items were obtained, and the aggregate split-half reliability coefficient was 0.922. The Cronbach's alpha coefficient for the five dimensions, i.e. Liver Meridian, relevant meridians, basic psychological activities, work cognition and emotional reactions, was respectively 0.841, 0.842, 0.914, 0.836 and 0.839, indicating a content internal consistency. The score of each item was highly correlated with the corresponding dimension, and the intercommunity was between 0.474 and 0.801. Nine factors were generated, 2 in the dimension of Liver Meridian, 3 in the dimension of relevant meridians, 2 in the dimension of basic psychological activities, 1 in the dimension of work cognition, and 1 in the dimension of emotional reactions, and the load of each factor was between 0.438 and 0.859. The reliability and validity of the scale were well examined. Conclusion: The scale can be applied to evaluate the qi activities of Liver Meridian and depression symptoms related to workplace.
