The college and hospital should take measures to provide essential guarantee for constructing the teaching system.

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 .

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.

In order to investigate the effects of electric pulses on cancer cells, we carried out the experiments with exposing HepG2 and L02 to electric pulses (1 kV/cm, l00 micros, 1 Hz) for different lengths of time (8 s, 15 s, 30 s, 60 s). Annexin V-FITC Kit and Flow cytometry were used to study the apoptosis of treated cells. The results showed that the electric pulses of 1 kV/cm, l00 micros, 1 Hz for 8 s could not induce tumor cells apoptosis. Apoptosis was observed when tumor cells were stimulated for 15 s and longer, and the apoptosis percentage increased with the increase of stimulation time. Furthermore, tumor cells were more sensitive than normal cells in response to electrical pulses. Rhodamine 123 and Laser Scanning Confocal Microscope (LSCM) were used to make a real-time study of mitochondrial transmembrane potential (Deltapsim) when the tumor cells were exposed to electric pulses for 60 s. No significant change of Deltapsim was observed within 30 s stimulation. After that, the Deltapsim increased sharply and declined later, suggesting that the mitochondrial pathway may be one of the apoptosis mechanism induced by electric pulses.
