Objective:To explore the effects of linagliptin on blood glucose, islet function and liver stiffness measurement (LSM) in patients with non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM).Methods:During the period from January 2019 to April 2020, 102 patients with NAFLD and T2DM in the Second Affiliated Hospital of Suzhou University were enrolled and divided into study group and control group according to different treatment methods, with 51 cases in each group. The control group was treated with metformin, while study group was treated with linagliptin and metformin. The clinical curative effect on fatty liver was observed and compared between the two groups. The levels of fasting blood glucose (FBG), glycated hemoglobin (HbA 1c), homeostasis model assessment of insulin resistance (HOMA-IR), homeostasis model assessment of islet insulin cell function index β (HOMA-β), alanine aminotransferase (ALT), serum aspartate aminotransferase (AST), glutamyl transpeptidase (GGT) and LSM before and after treatment were compared between the two groups. The occurrence of adverse reactions during treatment in both groups was recorded. Results:The total response rate of fatty liver treatment in study group was significantly higher than that in control group: 96.1% (49/51) vs. 82.4% (42/51), and there was statistical difference ( P<0.05). After treatment, levels of FBG, HbA 1c, HOMA-IR, serum ALT, AST, GGT and LSM in study group were significantly lower than those in control group: (7.1 ± 1.0) mmol/L vs. (7.9 ± 0.9) mmol/L, (7.5 ± 0.7)% vs. (7.9 ± 1.0)%, 3.2 ± 0.2 vs. 4.7 ± 0.3, (56.7 ± 10.4) U/L vs. (62.8 ± 8.2) U/L, (73.2 ± 6.8) U/L vs. (81.1 ± 6.7) U/L, (56.4 ± 10.2) U/L vs. (62.3 ± 8.1) U/L, (10.5 ± 3.3) kPa vs. (13.4 ± 1.6), the level of HOMA-β was significantly higher than that in control group: 48.5 ± 8.3 vs. 41.2 ± 7.1, and there were statistical differences ( P<0.05). The incidence of adverse reactions during treatment was low in both groups, and the difference was not statistically significant between the two groups ( P>0.05). Conclusions:Linagliptin can improve clinical curative effect on fatty liver in patients with NAFLD and T2DM, control blood glucose level, and improve islet function, liver function and liver fibrosis, with higher medication safety.

Objective To investigate in vitro anti-hydatid efficacy on Echinococcus granulosus protoscolex(EgPSC) by using albendazole sulfoxide(ASOX) and its two enantiomeric antipodes, L-ASOX and D-ASOX.Methods Eg protoscoleces were divided into eight groups and cultured in the DMEM culture media under two concentrations(50 ?g/ml and 100 ?g/ml) of ASOX, L-ASOX and D-ASOX respectively.The appropriate controls included(i) a culture containing an equal amount of DMSO and(ii) a culture medium alone.The mortality of EgPSC in each group was daily counted until 100% EgPSC death in some groups.Results Significant difference of EgPSC mortality was found among the three drugs with various concentrations compared to control group(P0.05), but between ASOX group and L-ASOX group(P

Objective:To create a large human phage antibody library from which easy to get diabody and select human antibody clones.Methods:VL and VH genes were amplified by RT-PCR from RNA which came from normal adult peripheral blood and new-born cord blood lymphocytes. VL and VH genes were reamplified to add a region of overlap in the ScFv linker to form ScFv genes in which VH genes were flanked by two non-homologous loxp sites. The ScFv genes were cloned into PDF to obtain a primary library. This primary library was used to infect bacteria Bs1365(expressing cre recombinase) with high multiplicity of infection(MOI) 200∶1. This procedure resulted in a very large phage antibody library through VL and VH recombined by the cre recombinase. Following recombination, phagemide were derived from these bacteria and used to infect bacteria not expressing cre(XL1-Blue) at MOI

[Objective]To investigate the effect of pantoprazole on skeletal muscle wasting in cancer cachexia and the possible mechanism.[Methods]24 male BALB/c mice were randomly divided into control group(NN),cancer cachexia group(CC),pantrop?razole treatment group(PPI). The mice in CC and PPI were inoculated subcutaneously with mouse colon adenocarcinoma C26 cells to establish a model of cancer cachexia. The mice in PPI group were gavaged with 75 mg/kg pantoprazole dissolving in physiological saline,while those in NN and CC group were gavaged with 0.1 mL/10 g physiological saline. The mice were killed 12d after treatment. The weight of gastrocnemius and tumour and the size of tumour were measured. The morphological change of skeletal muscle were evalu?ated by the method of stain with hematoxylin and eosin(H&E). The levels of IL-6 and TNF-αin serum were tested by ELISA. qRT-PCR was used to assess the expression of mRNA of Myod1 and myf5 in skeletal muscle. The protein expressions of MuRF1,MAFBx, Myod1 and myf5 were measured by Western blot.[Results]Compared with CC group ,pantoprazole can increase the weight of mice and gastrocnemius(39.8% and 24.2%,respectively),cross section area(25.4%),levels of mRNA and protein of Myod1 and myf5(P<0.05),while the levels of IL-6 and TNF-αdecreased(30.7%and 18.9%,respectively),as well as the levels of protein ex?pression of MuRF1 and MAFBx(P < 0.05).[Conclusion]Pantoprazole can attenuate the wasting of skeletal muscle,the potential mechanism may be related to the inhibition of inflammatory factors and UPS ,and up-regulation of Myod1 and myf5.

To study the function of expelling water retention with drastic purgative of different polarities of Kansui Radix stir-baked with vinegar on the cancerous ascites model rats, the furosemide was taken as positive control drug, and the cancerous ascites model rats were respectively orally administered with different polarities of Kansui Radix stir-baked with vinegar for 7 d. The amount of urine and ascites, the level of urinary sodium, potassium, chloride ion and pH, and the content of PRL1, AII, ALD in serum were investigated. Compared with model groups, ethyl acetate extract group showed a decreasing trend in ascites; the amount of urine of showed a significant increase (P < 0.05); the level of urinary sodium, potassium, chloride ion (P < 0.05, P < 0.01), pH (P < 0.05), and the content of PRL1, AII, ALD in serum all showed a significant decrease (P < 0.01). The effects of petroleum ether extract and n-butanol extract were weaker than that of ethyl acetate extract. The water exact was the weakest. The results showed that ethyl acetate extract is the active part of Kansui Radix stir-baked with vinegar on the function of expelling water retention with drastic purgative on the cancerous ascites model rats, alleviating the water-electrolyte disorder and body fluid acid-base imbalance, regulating the renin angiotensin aldosterone system.

To reveal the variation of polysaccharides and alcohol-soluble extract contents of Dendrobium officinale, the polysaccharides and alcohol-soluble extracts contents of three D. officinale strains were determined by phenol-sulfuric acid method and hot-dip method, respectively. The results showed that the contents of polysaccharides and alcohol-soluble extracts and their total content were significantly different among D. officinale samples collected in different periods, and the variations were closely related to the phenology of D. officinale. Additionally, the quality variation of polysaccharides was closely related to the flowering of D. officinale, while the alcohol-soluble extracts was closely associated to the formation and germination of buds. According to the dynamic variation of these two compounds, it is more reasonable to harvest D. officinale at biennials pre-bloom than at specific harvesting month considering polysaccharides content. It is better to harvest before the germination of buds considering alcohol-soluble extracts. While with regards to both polysaccharides and alcohol-soluble extract, it is better to harvest this plant at the period from the sprouting to pre-bloom next year.
