[Summary] A selection of 528 unrelated subjects were enrolled(198 males, 330 females) with the mean age of(52. 23 ± 13. 41) years old. According to body mass index, 253 persons belonged to the normal weight group and 275 persons overweight/ obesity group. A total of 10 SNPs in CIDEB and CIDEC genes were detected. SHEsis online were used to get the haplotypes of these two genes. The relationship between above SNPs and obesity were analyzed under additive inheritance pattern. The main effects and interaction on obesity induced by two genes’ haplotypes were analyzed by logistic regression. rs2144493 in CIDEB gene was associated with obesity, C was a protective alleles, OR (95% CI) equals 0. 722(0. 525-0. 992). CCTT haplotype of CIDEB gene carriers and GCG haplotype of CIDEC gene carriers were more prone to obesity or overweight, there was an interaction between the haplotypes of 2 genes. CIDEB, CIDEC haplotypes may play independent and interactive roles in causing obesity.

Objective To investigate the effect of herpes simplex virus thymidine kinase/ganciclovir (HSV-TK/GGV)system driven by human alpha fetoprotein(AFP)enhancer on hepatocellular carcinoma(HCC)cells in vitro and in vivo.Methods HCC-specific eukarotypic expression vector carrying suicide gene driven by AFP enhancer(pAFP-cDNA3.1-TK)was constructed.The plasmid was trasfected to AFP-positive HepG2 cells and AFP-negative SMMC7721 cells by liposomes.Protein and mRNA expressions of TK were detected by RT-PCR or Western blot.The survival rates of HCC cells were detected by methyl thiazolyl tetrazolium assay.The effects of GGV on the in vitro proliferation,survival and apoptosis of HCC cells were observed,and the inhibitive effect of GGV on the survival of HCC cells in vivo was also detected.All data were analyzed by using the t test.Results The pAFP-cDNA3.1-TK was successfully constructed and transfected to the HCC cells.The protein and mRNA expressions of TK were detected in AFP-positive HepG2 cells.GGV dose-and time-dependently inhibited the growth and induced the apoptosis of HepG2 cells in vitro,but it had no effect on SMMC7721 cells.No protein or mRNA expression of TK was detected in the SMMC7721 cells.There was a significant difference on the inhibitory effects of GGV on HepG2 cells and SMMC7721 cells(t =2.58,2.73,3.12,P ＜0.05).GGV specifically inhibited the growth of AFP-positive HepG2 cells,and the inhibition rate was 46%;the growth of AFP-negative SMMC7721 cells was not influenced by GGV.There was a significant difference in the inhibitive effect of GGV on the growth of HepG2 cells and SMMC7721 cells(t = 3.36,P ＜ 0.05).Conclusion HSV-TK/GGV systemdriven by human APF enhancer kills APF-positive HCC cells and inhibits the growth of HCC cells.

Objective To study the early prediction of infection in acute pancreatitis in rats by plasma procalcitonin (PCT) and c-reactive (CRP) detection.Methods Eighty SD rats were randomly assigned into acute infected pancreatitis group (I, n=20), pancreatitis control group (C, n=40) and sham-operated group (S, n=20). Blood samples were collected pre- (0h) and post-operatively (12h, 24h and 48h). Plasma CRP was analyzed by ELISA. Plasma and liver PCT was detected by Western blot.Results (1). Ascitic infection occurred in all the group B rats and 16 of 40 rats of group C (analyzed as group C1), and did not occur in the other 20 of 40 rats of group C (analyzed as group C2) and group S. (2). The plasma CRP concentrations elevated gradually after the model setup in group B and C1, which were significantly higher at 48h than those in group C2 and group S. (3). PCT was detected in high levels in plasma and liver tissues in group B and C1 at 48h post-operatively, and they were sighificantly higher than those in group C2 and group S.Conclusions PCT can predict early infection of acute pancreatitis, and detection of PCT combined with plasma CRP may help in the differentiation of acute infected pancreatitis. The liver may be an important organ for synthesis of PCT.

ObjectiveTo study the value of C-reactive protein (CRP) and interleukin-6(IL-6) in the (diagnosis) of acute pancreatitis (AP) associated with infection. MethodsSixty SD rats were randomly (assigned) into group AP (n=40) and sham-operation group (S, n=20). Plasma CRP and IL-6 were detected before AP(0h), and at 12h, 24h and 48h after AP. Serum amylase detection and ascitic bacteria culture were carried out at 48h. Results(1)In AP group, 36 rats were alive. Ascitic infection developed in 16 cases (group AP1), and not in the other 20 cases (group AP2). (2)Plasma CRP and IL-6 levels in group AP1 and AP2 were significantly higher than those in group S (all, P0.05). (3)In group AP1, IL-6 and CRP elevated significantly at all time periods after the model setup (P0.05). (Conclusions)Plasma CRP has predictive value in the diagnosis of early infection in acute pancreatitis, but plasma IL-6 is not sensitive to secondary bacteria infection in acute pancreatitis.

Objective To explore the association between the CpG methylation level of positive regulatory domain containing 16(PRDM16)gene promoter and obesity or body mass index(BMI). Methods A total of 116 patients(91 female adults and 25 male adults) with abdominal operation in a municipal hospital of Henan province were enrolled in this study and they were divided into two groups:normal weight group(n=50), overweight or obesity group ( n=66 ) . Fasting plasma glucose, total cholesterol, triglyceride, high density lipoprotein and low density lipoprotein were measured in peripheral blood. DNA was extracted from white blood cells in peripheral blood and modified by bisulphite. Then the CpG methylation level of PRDM16 gene promoter was detected by mass spectrometry. Finally, all data were analyzed by IBM SPSS Statistics 21. 0 at the 5% level. The essential features and biochemical indexes of research objects between two groups were compared by two independent sample t-test, except chi-square test for gender. The correlation between CpG methylation level of PRDM16 gene and BMI was analyzed by multiple linear regression. Results There were no significant differences ( P>0. 05 ) in the methylation levels of PRDM16 gene's effective CpG sites(including CpG5. 6, CpG8, CpG9, CpG12, CpG13. 14. 15, CpG26. 27, CpG28 and CpG29) between two groups. The methylation level of CpG26. 27 had positive linear relation with BMI in overweight or obesity group with the standardized coefficients of 46. 928(P=0. 015), which means the higher the methylation level is, the higher the BMI would be. Conclusion The CpG26. 27 methylation level of PRDM16 gene promoter region may have relationship with the risk of obesity.

Objective:To investigate the nutritional risk and prevalence of malnutrition in patients with terminal stage gastrointestinal malignant tumors in a tertiary hospital in Changsha.Methods:Cluster sampling was used to conduct a cross-sectional survey of inpatients from Departments of Gastroenterology, Gastrointestinal Surgery, Hepatobiliary Surgery and Oncology in Hunan Provincial People's Hospital from January 2019 to July 2020. Nutritional Risk Screening 2002 (NRS 2002) was used to assess the prevalence of nutritional risk with malnutrition defined as concurrent presence of BMI < 18.5 kg/m 2, poor general condition and NRS 2002 nutritional impairment score of 3. Step 2 of Global Leadership Initiative on Malnutrition (GLIM) diagnostic criteria (without whole body muscle mass) was adopted to diagnose malnutrition. Step 3 of GLIM criteria was used to evaluate the prevalence of severe malnutrition. Results:A total of 802 patients registered in the 4 departments were selected for screening via cluster sampling and 514 were enrolled according to the inclusion/exclusion criteria. The prevalence of nutritional risk in patients with terminal stage gastrointestinal cancer was 49.8% (256/514). The prevalence of malnutrition and severe malnutrition per GLIM criteria were 41.6% (214/514) and 18.3% (94/514), respectively.Conclusions:Although nutritional support therapy is not recommended for patients with end-stage cancer. This paper suggests that the prevalence of nutritional risk and malnutrition in patients with end-stage gastrointestinal cancer is not as high as described in some articles.

Effective expression of pIFN-α in recombinant Pichia pastoris was conducted in a 5 L fermentor. Ethanol accumulation during the late glycerol feeding period inhibited heterologous protein expression. Comparative transcriptome analysis was thus performed to compare the gene transcription profiles of Pichia pastoris KM71H in high and low ethanol concentration environments. The results showed that during the glycerol cultivation stage, 545 genes (265 up-regulated and 280 down-regulated) were differentially expressed with ethanol stress. These genes were mainly involved in protein synthesis, energy metabolism, cell cycle and peroxisome metabolism. During the methanol induction stage, 294 genes (171 up-regulated and 123 down-regulated) were differentially expressed, which were mainly related to methanol metabolism, amino acid metabolism and protein synthesis. Ethanol stress increased protein misfolding and reduced structural integrity of ribosome and mitochondria during cultivation stage, and led to the failure of endoplasmic reticulum stress removal and damaged amino acid metabolism during induction stage in Pichia pastoris.
