Increased evidences indicate that resistin is a new hormone secreted from adipose tissue, it is reported to be an important signal molecule linking between obesity,insulin resistance and type 2 diabetes. Many factors can affect the gene expression of resistin. However, the detailed function of resistin still remains mysterious and much work needs to be undertaken. [

Objective The antimicrobial peptide LL-37 ( LL-37) is the mature form of Human Cationic Antimicrobial Pep-tide of 18kD (hCAP18) and play a certain regulation role in the pathogenesis of asthma .However, the mechanism is unclear.The aim of this study was to investigate the role of inflammatory release from human eosinophils induced by the antimicrobial peptide LL -37 in the pathogenesis of asthma and the underlying mechanisms . Methods Sixteen mild or medium allergic asthma patients from January 2015 to January 2016 in Panzhihua college affiliated hospital were enrolled .Another 16 healthy volunteers were enrolled as control .Pri-mary eosinophils were isolated from peripheral blood .The cells were divided into two groups:asthma group and healthy control group . Cells were divided into blank , PAF, LL37, single cytokine ( IL-5, GM-CSF) and cytokines combined with LL-37 group based on in-tervention (cell treating factors) difference;Cells were divided into PTx, WRW4, suramin, and LL-37 combined with inhibitors group based on inhibitors difference;Cells were grouped into LTD 4 and LTB4 treatment based on leukotrienen difference;ELISA was applied to analyze cysteinyl leukotrienes ( cys-LTs) level in various treatment groups;Western blot was used to detect change of cPLA 2, p-cP-LA2, ERK1/2, p-ERK1/2 in the cells from the control group after PTx and WRW 4 treatment and the level of hCAP 18 after leukot-riene treatment. Results Compared with the control 15 μg/mL LL-37 sub group, the expression of Cys-LTs was increased in the control 30μg/mL LL-37 sub group 15 and 30 minutes after the LL-37 treatment [(54.02±7.15) pg/105 vs (37.86±6.33) pg/105, (53.30±6.99) pg/105 vs (36.27±6.46) pg/105, P<0.05].Compared with the control IL-5 sub group (26.18±4.86) pg/105, the ex-pression of Cys-LTs was increased in the control IL-5+15 μg/mL LL-37 sub group (59.97±6.83) pg/105 and the control IL-5+30μg/mL LL-37 sub group (81.44±13.70) pg/105(P<0.05).Compared with the control sub group , the expression of Cys-LTs was in-creased in the asthma 15 μg/mL LL-37 sub group and the asthma 30μg/mL LL-37 sub group ( P<0.05) .Compared with the control LL-37 sub group, the expression of Cys-LTs was decreased in the control PTx sub group , control WRW4 sub group, control suramin sub group, control PTx +LL-37 sub group, and control WRW4+LL-37 sub group (P<0.05).Western blot results indicated that LL-37 treatment induced the activation and phosphorylation of ERK 1/2 in eosinophil, and PTx and WRW4 blocked the upregulation of pERK1/2 induced by LL-37.Treatment with PD inhibited the phosphorylation of cPLA 2 and the release of Cys-LTs induced by LL-37. hCAP18 was higher in the asthma groups than the healthy control . Conclusion LL-37 was identified as an eosinophil-activating pep-tide that could trigger the release of inflammatory mediators , which might be involved in occurrence and development of asthma through regulating ERK1/2 phosphorylation, inducing cPLA2 phosphorylation and finally initiate synthesis of cys-LTs.This suggests that LL-37/hCAP18 and its signaling pathway might be potential therapeutic targets for asthma .

The non-affiliated hospital’s teaching system in college includes teaching administration system, teaching operation system and teaching quality supervision and evaluation system. It is the significant step for the non-affiliated hospital to assume the clinic teaching duties that constructs the teaching system. The college and hospital should take measures to provide essential guarantee for constructing the teaching system.

We have designed and carried out problem based learning (PBL) pedagogy since 2004. According to clinical eases, students learnt the pathophysiology of heart failure knowledge by themselves. Each group recommen-ded one student to make an oral presentation and wrote a review about heart failure. Preparing clinical cases and group discussions are very important. At the same time we should pay attention to the change in role of the teacher in PBL and cooperation with other disciplines.

Objective To observe the expression of HER-2 and TOPO-Ⅱα in ovarian epithelial cancer,analyze the correlation between their expression and provide theoretical basis for clinical diagnosis,prognosis and treatment. Methods Expression levels of HER-2 and TOPO- Ⅱα in 10 normal ovarian tissues,20 benign tumors and 58 cases of ovarian epithelial cancers were detected by immunohistochemical method, and their correlations with pathological features were analyzed. Results The positive expression rate of HER-2 in normal ovarian and benign tumor tissues were significantly lower than ovarian epithelial cancers respectively ( 10. 0% , 15.0% VS 46. 6% ;P ＜ 0. 05 ). The positive expression rate of TOPO- Ⅱα in ovarian epithelial cancers was significantly higher than normal and benign epithelial ovarian tumor tissue (53.4% vs 10. 0%, and 15.0%,Ps ＜ 0. 05 ), but we did not find significant difference in the comparison between normal and benign epithelial ovarian tumor tissue ( Ps ＞ 0. 05 ). The expression of HER-2 and TOPO- Ⅱα were significantly correlated with clinical stages, histological differentiation of tumor cells (Ps ＜ 0. 05 ) ,but there were no correlations between the age or histological type. In ovarian cancer tissues, a positive correlation between the expression of HER-2 and TOPO- Ⅱα was observed ( r = 0. 324, P ＜ 0. 05 ) . Conclusion The overexpression of HER-2 and TOPO- Ⅱαplay an important role in ovarian carcinogenesis and development. The expression of HER-2 is positively correlated with TOPO- Ⅱα in ovarian epithelial cancers. Coexpression of the two moleculars may be involved in the development and progression of ovarian epithelial cancer, which should be further studied.

Objective To compare the differences in cognitive function and behavioral and psychological symptoms between patients with Alzheimer's disease (AD) and behavioral variant frontotemporal dementia (bvFTD). Methods Thirty-six AD patients and 20 bvFTD patients at mild-to-moderate stage, who were biomarker-confirmed by positron emission tomography (PET), were assessed with a neuropsychological battery and neuropsychiatry inventory (NPI). Cognitive domains, including memory, language, information processing speed and executive function, and behavioral and psychological symptoms were assessed and compared. Results AD patients had lower scores in immediate recall, delayed recall and recognition than bvFTD patients (all P<0.05); while bvFTD patients had poorer performance in language and executive function than AD patients (all P<0.05). The NPI total score was significantly higher in patients with bvFTD compared with patients with AD (17.5±5.7 vs 9.3±3.5, P<0.05). In respect to the 12 items of NPI, the incidence of agitation and irritability was higher in AD group than in bvFTD group (72.2%vs 35.0%, 55.6%vs 20.0%, all P<0.05);while the incidence of apathy, disinhibition, euphoria, aberrant motor behavior and appetite/eating was higher in bvFTD group than in AD group (65.0%vs 33.3%, 80.0% vs 5.5%, 70.0% vs 5.6%, 40.0% vs 11.1%, 50.0% vs 5.6%, all P<0.05). Conclusion Comprehensive neuropsychological assessment and evaluation of behavioral and psychological symptoms of patients with dementia are helpful in distinguishing AD from bvFTD.

Objective: This study examined the gut bacterial communities of dogs from different breeds, all kept under identical domestication conditions. Methods: Noninvasive sampling and 16S rRNA high-throughput sequencing were used to compare the composition and function of the gut microbiota of three dog breeds: the Chinese Kunming dog (CKD), German Shepherd dog (GSD), and Belgian Malinois dog (BMD). Results: The gut microbiota of the three dog breeds consisted of 257 species across 146 genera, 60 families, 35 orders, 15 classes, and 10 phyla. The dominant bacterial phyla across the three breeds were Firmicutes (57.44%), Fusobacteriota (28.86%), and Bacteroidota (7.63%), while the dominant bacterial genera across the three breeds were Peptostreptococcus (21.08%), Fusobacterium (18.50%), Lactobacillus (12.37%), and Cetobacter (10.29%). Further analysis revealed significant differences in the intestinal flora of the three breeds at the phylum and genus levels. The intestinal flora of BMD was significantly richer than that of CKD and GSD. The functional prediction and Kyoto Encyclopedia of Genes and Genomes analysis showed that the primary functions of the gut microbiota in these breeds were similar, with significant enrichment in various metabolic pathways, including carbohydrate and amino acid metabolism, secondary metabolite biosynthesis, and microbial metabolism in different environments. The intestinal flora of these breeds also played a crucial role in genetic information processing, including transcription, translation, replication, and material transport. Conclusions and Relevance: These results provide novel insights into the intestinal flora of intervention dogs and suggest novel methods to improve their health status, which help increase microbial diversity and normalize metabolite production in diseased dogs.
