Objective To investigate the relationship between waist circumference and new-onset non-alcoholic fatty liver disease in non-obese patients with diabetes mellitus. Methods A total of 1 950 patients with diabetes mellitus, who determined fasting plasma glucose(FPG)≥7.0 mmol/L or who were using hypoglycemic drugs and FPG<7.0 mmol/L,and body mass index (BMI)< 25 kg/m2, was selected in this study using prospective cohort method. Patients were divided into five groups according to the baseline data of waist circumference, including waist circumference<78 cm (A group, n=387), 78 cm90 cm (E group, n=421). Multiple Logistic regression model was used to analyze influential factors of new-onset non-alcoholic fatty liver disease in non-obese patients with diabetes mellitus. Re?sults The average duration of follow-up was(47.24±5.13) months. The incidence rate was 11.85%(231/1 950) in patients with non-alcoholic fatty liver disease. The incidence rates were 6.98%, 9.28%, 12.38%, 14.19%and 15.68%in A, B, C, D and E groups, and which were increased with the increased waist circumference (P<0.05). Results of multiple Logistic re?gression model analysis showed that compared with A group,OR values were 1.97 and 2.19 in D and E groups respectively (P<0.05). Conclusion Waist circumference≥85 cm was the risk factors of new-onset non-alcoholic fatty liver disease in non-obese patients with diabetes mellitus.

[ ABSTRACT] AIM:To investigate the effects of tanshinone IIA ( Tan IIA) on proliferation, apoptosis and its mo-lecular mechanism in human hepatoma HepG2 cells under hypoxic condition.METHODS:Hypoxia model was established by treatment with cobalt chloride ( CoCl2 ) .The cells were divided into normoxia control group, hypoxia control group and hypoxia combined at different concentrations of Tan IIA groups.After HepG2 cells were incubated with different concentra-tions of Tan IIA (0.5, 1.0, 2.0, 5.0 and 10.0 mg/L) for 24 h, 48 h and 72 h under hypoxic condition, the cell prolifer-ation was determined by MTT assay.After Tan IIA was added to the media at different concentrations for 24 h and 48 h, the apoptotic cells were observed by Hoechst 33258 staining.The protein levels of hypoxia-inducible factor 1 alpha (HIF-1α) , vascular endothelial growth factor ( VEGF) and wild-type P53 were detected by Western blotting after cultured with different concentrations of Tan IIA for 48 h.RESULTS:Tan IIA inhibited the proliferation of HepG2 cells in a dose-and time-dependent manner.Tan IIA induced the typical morphology of apoptotic cells and increased the apoptotic rate in a dose-and time-dependent manner after treatment with 1.0 mg/L~5.0 mg/L for 24 h and 48 h under hypoxic condition. The protein levels of HIF-1αand VEGF were weakly expressed in HepG2 cells under normoxia but up-regulated after incu-bated under hypoxia for 48 h.The protein expression of HIF-1αand VEGF were decreased with the increase in the concen-tration of Tan IIA under hypoxia.The protein expression of wild-type P53 was increased with the increase in the concentra-tions of Tan IIA under hypoxia.CONCLUSION:Tan IIA significantly inhibits the proliferation and induces the apoptosis of human hepatoma HepG2 cells under hypoxia, which may be related to the down-regulation of HIF-1αand VEGF and up-regulation of wild-type P53.

Aim To investigate the mechanism of demethylation on adenosine (ADO )and homocysteine (HCY)-induced apoptosis in human hepatoma HepG2 cells .Methods HepG 2 cells were treated with differ-ent concentrations of ADO (1.0、2.0、4.0 mol · L-1 ) alone or in combination with HCY for 6h,12h and 24h,5-aza-2-deoxycytidine (5-Aza-CdR)as a positive control.Cell viabilities were assessed by CCK8 assay. Cell apoptosis was observed by AnnexinV-FITC/PI staining.The mitochondrial membrane potentials(ΔΨ) were measured by flow cytometry.The mRNA and pro-tein expressions of caspase-3,caspase-8,caspase-9, MDM-2,p53,Cytochrome C,DNMT1,DNMT3a,DN-MT3 b were detected by RT-qPCR and Western blot re-spectively.Results ADO alone or in combination with HCY significantly reduced the viability of HepG2 cells in a dose and time-dependent manner.The apoptotic rates of HepG2 cells after combination treatment with ADO and HCY at 1 .0,2.0,4.0 mol · L-1 for 24 h were (1 8.63 ± 1.25 )%,(29.42 ±2.37 )% and (42.47 ±3.09 )%,compared with the control group (1.30 ±0.82 )%,P <0.01;and the mitochondrial membrane potentials were decreased from 674.15 ± 82.8%(black control group)to (428.38 ±54.5)%, (297.78 ±30.5)%,(74.45 ±5.73)%,P<0.01, respectively.The expressions of caspase-3,caspase-8, caspase-9,MDM-2,p53,Cytochrome C were up-regula-ted and MDM-2 were down-regulated after combination treatment of ADO and HCY.The mRNA expressions of DNMT1 ,DNMT3 a and DNMT3 b were down-regulated after combination treatment with ADO and HCY or 5-Aza-CdR alone.Conclusion Combination treatment of ADO and HCY can cause cellular methylation chan-ges.The effects of demethylation of ADO and HCY may activate p53 gene and mitochondrial pathway, which at last leads to HepG2 cell apoptosis.

The heterogeneity and complexity of malaria involves political and natural environments, socioeconomic development, cross-border movement, and vector biology; factors that cannot be changed in a short time. This study aimed to assess the impact of economic growth and cross-border movement, toward elimination of malaria in Yunnan Province during its pre-elimination phase. Malaria data during 2011-2016 were extracted from 18 counties of Yunnan and from 7 villages, 11 displaced person camps of the Kachin Special Region II of Myanmar. Data of per-capita gross domestic product (GDP) were obtained from Yunnan Bureau of Statistics. Data were analyzed and mapped to determine spatiotemporal heterogeneity at county and village levels. There were a total 2,117 malaria cases with 85.2% imported cases; most imported cases came from Myanmar (78.5%). Along the demarcation line, malaria incidence rates in villages/camps in Myanmar were significantly higher than those of the neighboring villages in China. The spatial and temporal trends suggested that increasing per-capita GDP may have an indirect effect on the reduction of malaria cases when observed at macro level; however, malaria persists owing to complex, multi-faceted factors including poverty at individual level and cross-border movement of the workforce. In moving toward malaria elimination, despite economic growth, cooperative efforts with neighboring countries are critical to interrupt local transmission and prevent reintroduction of malaria via imported cases. Cross-border workers should be educated in preventive measures through effective behavior change communication, and investment is needed in active surveillance systems and novel diagnostic and treatment services during the elimination phase.

Objective:To construct the pET30a-EgG1Y162-2 prokaryotic expression plasmid and induce the expression of EgG1Y162-2 protein, so as to provide a research basis for development of Echinococcus granulosus vaccine. Methods:Using Echinococcus granulosus cDNA as a template, the target gene of EgG1Y162-2 was synthesized by PCR, and after digestion with restriction enzymes EcoRⅠ and Hind Ⅲ, it was connected to the prokaryotic expression vector pET30a to construct the recombinant plasmid pET30a-EgG1Y162-2. The recombinant plasmid was transformed into competent cell BL21 (DE3) and induced by isopropyl β-D-thiogalactoside (IPTG) to express a large number of proteins. The recombinant protein was purified by affinity chromatography. The purification level was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), and the expression product was identified by Western blotting. Results:The recombinant plasmid pET30a-EgG1Y162-2 was successfully constructed. After inducting expression, the bacterial supernatant and the eluate were both at a relative molecular weight of about 15 × 10 3, and the protein antigen component eluted with 200 mmol/L imidazole was relatively pure. Western blotting results showed that the purified recombinant protein EgG1Y162-2 with His tag could be recognized by His monoclonal antibody. Conclusion:The pET30a-EgG1Y162-2 prokaryotic expression plasmid of Echinococcus granulosus is successfully constructed, and the recombinant protein of EgG1Y162-2 is induced to express, laying a foundation for further study on anti- Echinococcus granulosus vaccine.

As a representative foreign medicinal material, olibanum(Ruxiang) was imported to China since the Qin and Han Dynasties. Olibanum was first described as a medicinal by the name "Xunluxiang" in Miscellaneous Records of Famous Physicians(Ming Yi Bie Lu). This study investigated historical records on olibanum and conducted the herbalogical study. It was found that olibanum came from the resin mainly obtained from the bark of Pistacia lenticus before the Tang Dynasty. With the prosperity of the Maritime Silk Road, instead, the resin obtained from the bark of Boswellia carterii was mainly used as olibanum. In ancient time, the oleo-gum-resin secreted from the cut bark was collected in spring and summer, and the quality was judged based on transparency and shape. The processing methods of olibanum went through many evolutions, which changed from simple methods such as grinding and frying to complex methods such as levigating and grinding with wine, and now to frying and processing with vinegar. The usage of olibanum included alchemy, folk and religious incense, bathing, cosmetic and medicinal since ancient times. From the Song Dynasty, olibanum had been mainly used as medicinal because of its good effect to treat wounds. In traditional Chinese medicine, olibanum unblocks menstruation, relieves pain and reduces swelling and generated muscles. The medicinal efficacy of olibanum is not much different from ancient to modern. Only the efficacy of replenishing energy and promoting the movement of Qi was rarely mentioned in modern reference. In this article, the historical evolutions of olibanum about original plants, processing and medicinal efficacy were sorted out. The results could provide historical basis for the further development and clinical utilization of olibanum.
