Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide. Fat accumulation "sensitizes" the liver to insult and leads to nonalcoholic steatohepatitis (NASH). G protein-coupled receptor 35 (GPR35) is involved in metabolic stresses, but its role in NAFLD is unknown. We report that hepatocyte GPR35 mitigates NASH by regulating hepatic cholesterol homeostasis. Specifically, we found that GPR35 overexpression in hepatocytes protected against high-fat/cholesterol/fructose (HFCF) diet-induced steatohepatitis, whereas loss of GPR35 had the opposite effect. Administration of the GPR35 agonist kynurenic acid (Kyna) suppressed HFCF diet-induced steatohepatitis in mice. Kyna/GPR35 induced expression of StAR-related lipid transfer protein 4 (STARD4) through the ERK1/2 signaling pathway, ultimately resulting in hepatic cholesterol esterification and bile acid synthesis (BAS). The overexpression of STARD4 increased the expression of the BAS rate-limiting enzymes cytochrome P450 family 7 subfamily A member 1 (CYP7A1) and CYP8B1, promoting the conversion of cholesterol to bile acid. The protective effect induced by GPR35 overexpression in hepatocytes disappeared in hepatocyte STARD4-knockdown mice. STARD4 overexpression in hepatocytes reversed the aggravation of HFCF diet-induced steatohepatitis caused by the loss of GPR35 expression in hepatocytes in mice. Our findings indicate that the GPR35-STARD4 axis is a promising therapeutic target for NAFLD.

Objective:To screen the key exosomal long non-coding RNAs (lncRNAs) molecules that cause nasopharyngeal carcinoma cells to develop chemoradiotherapy resistance.Methods:In vitro, a model of concurrent chemoradiotherapy for human nasopharyngeal carcinoma cells was constructed, and the continuous shock method of high-dose concurrent chemoradiotherapy was used to induce the establishment of chemoradiotherapy-resistant nasopharyngeal carcinoma cell lines, and its resistance formation was verified. Exosomes produced by chemoradiotherapy-resistant cell lines and respective mother cell lines for nasopharyngeal carcinoma were extracted and identified. Finally, biochip technology was used to detect the differential expression levels of exosomal lncRNAs. Results:After 10 repeated treatments of concurrent chemoradiotherapy, CNE-1 CRR and CNE-2 CRR were successfully obtained. Compared with the mother cell lines, CNE-1 CRR and CNE-2 CRR had a tendency to transform from epithelial to interstitial morphology, and the number of cell clones was higher, and the values of average lethal dose (D 0), quasi-threshould dose (D q), survival fraction after 2 Gy irradiation (SF 2) and cell survival rate were higher. Nasopharyngeal carcinoma cells were detected by PCR chip of exosomal lncRNAs. Compared with their respective mother cell lines, 18 lncRNAs in CNE-1 CRR exosomes were significantly up-regulated and 31 lncRNAs were significantly down-regulated, and 15 lncRNAs were significantly up-regulated and 38 lncRNAs were significantly down-regulated in CNE-2 CRR exosomes. CNE-1 CRR also had similar expression profiles to CNE-2 CRR. Conclusion:There are significantly up-regulated and down-regulated lncRNAs in the exosomes of CNE-1 CRR and CNE-2 CRR.

Objective: To investigate genotypes and drug susceptibility of the 100 strains of Candida glabrata isolated from 100 women (including 50 pregnant women) in order to study the drug-resistance and gene polymorphism, and to investigate the correlation of drug-resistance, gestation and gene polymorphism. Methods: Multilocus sequence typing (MLST) technique was introduced to identify sequences of 6 housekeeping genes from 100 isolates of Candida glabrata. The results were compared with sequence information in MLST databases by Clustalx software to determine a strain allelic profile and sequence type (ST). Drawing the phylogenetic tree by weighted paired group average method and the minimal spanning tree method of MEGA6.0 software, the microevolution and relationship between different strains were analyzed. ATB FUNGUS semi-automatic system was used to test the drug susceptibility. Fisher analysis method was used to analyze the correlation between the genotypes and pregnancy.Ridit analysis method was used to analyze the correlation between the genotypes and drug susceptibility. Results: The 100 isolates belonged to 34 clone sequences. There were 53 isolates belonged to ST-7 ( 26 isolates of pregnancy), 7 isolates belonged to ST-3 (3 isolates of pregnancy), 6 isolates belonged to ST-19 (5 isolates of pregnancy ), 3 isolates belonged to ST-15 (1 isolate of pregnancy), 2 isolates belonged to ST-10 (2 isolates of pregnancy), 1 isolate belonged to the other types of ST. Total of 100 isolates of Candida glabrata were 100% sensitive to fluorocytosine and amphotericin. The effect of itraconazole was poor with the sensitive rate of 20%. The resistance rates of fluconazole and voriconazole were 4% and 1% respectively. All genotypes were sensitive to voriconazole except ST-X1. In the correlation between genotype and itraconazole resistance, ST-7 as the standard group, the Ridit values in the group of ST-15, ST-19 and other types of ST were not included the mean Ridit value of the standard group in itraconazole (0.5). The system evolution tree was built using the neighbor-joining method (NJ) . All genotypes could be divided into 3 groups, as Ⅰ, Ⅱ, Ⅲ. Group Ⅰ had 44 cases, group Ⅱ had 53 cases , group Ⅲ had 3 cases . All the collected clinical strains had small genetic distances during molecular evolution. Conclusions ST-7 was the dominant genotype in Guiyang. No correlation between different STs and patients′ pregnancy was found. The different drug susceptibility in itraconazole between ST-7, ST-15, ST-19 and other STs were found. The Candida glabrata associated with VVC showed highly discrimative diversity. However, the phylogenic analysis exhibited genetic similarity among the strains studied.(Chin J Lab Med, 2018, 41: 596-600)

Objective To investigate the status quo of occupational stress debugging ability of tumor specialist nurses and explore its influencing factors, so as to provide theoretical basis for reducing the work stress of tumor specialist nurses. Methods In June 2017, a total of 70 nurses in oncology department of He'nan Cancer Hospital were selected by convenience sampling method. Adversity quotient (AQ) Scale was used to assess the level of occupational stress debugging. Multivariate linear regression analysis was applied to analyze the influencing factors of nurses' occupational stress debugging level. Results The levels of the occupational stress debugging of nurses in Oncology Department was (14.66±4.57), at a mid-low level.
