AIM: To investigate the effect of purifried L-amino acid oxidase (LAO) from bungarus fasciatus snake venom on apoptosis and growth of HUVCE cell line. METHODS: The L-amino acid oxidase was purified by SP-sepharose HP column followed by Heperin-Sepharose (FF) column. The homogeneity of the preparation was examined by SDS-PAGE and the molecular weight of LAO was determined by SDS-PAGE and high performance liquid chromatography (HPLC) gel-filtration. The MTT assay was used to detect the viability of cells. Flow cytometry and laser confocal microscopy were used to identiyfy the cell cycle and apoptotic morphology after cells treated with LAO. RESULTS: An L-amino acid oxidase (BF-LAO) was successfully purified from the venom of bungarus fasciatus. It showed a single band in SDS-PAGE under both reduced and non-reduced conditions. The apparent molecular weight was determined to be 60 kD by SDS-PAGE and 70 kD by HPLC gel filtration. LAO inhibited growth and induced apoptosis of HUVCE cell line in a dose-dependent manner after 12 h incubation, with the 50% inhibitory concentration (IC_ 50 ) being of 2.8 mg/L. Flow cytometry and laser confocal microscope showed a typical apoptotic peak and morphological changes of these cells. CONCLUSION: The L-amino acid oxidase from bungarus fasciatus snake venom could inhibit the HUEVC cell growth and induce the cell apoptosis.

Objective To explore the influencing factors during long-distance transportation and medical rescue of trauma patients in Wenchuan earthquake. Methods After Wenchuan earthquake, based on prehospital care scheme, we organized medical coordinators and psychologically trained medical staff in emergency medicine, cardiovascular medicine and logistics to transport trauma patients and pro-vide early psychological intervention during whole course of transportation. Results A total of 162 trauma patients were safely transported from Sichuan province to Chongqing relying on prehospital care scheme, equipment supplies, integrated rescue mode and psychological intervention during the transporta-tion. Conclusions Medical rescue mode and psychological intervention indicate that it is necessary to conduct psychological intervention for better transportation of patients for further medical treatments. In the meantime, we should establish medical rescue system for coping with psychological stress, improve rescue preparation scheme and professional medical care team for long-distance transportation and guaran-tee sufficient medical supplies in station hospitals.

AIM: To investigate the levels of IL-18, IL-16, IL-8, eotaxin and the chymase activity in the sputum of asthmatics. METHODS: IL-18, IL-16, IL-8 and eotaxin levels were detected with sandwich ELISA procedures and chymase activity was determined spectrophotometrically (410 nm) by the rate of hydrolysis of N-succinyl-L-Ala-L-Ala-L-Pro-L-Phe-p-nitroanilide (SAAPP). RESULTS: The specific chymase activities in the severe and moderate asthmatics were higher than that in controls. Native protease inhibitors ?_1-antitrypsin (?_1-AT) and soybean trypsin inhibitor (SBTI) inhibited 71.9% and 72.1% enzymatic chymase activity, respectively. The levels of IL-18, IL-16, IL-8 and eotaxin were significantly elevated in the sputum of patients with acute asthma. There were correlations between the levels of IL-8 and IL-16 (r=0.55, P

AIM: To investigate the ability of Chinese cobra snake venom-metalloproteinase(MT) to induce the histamine release from human mast cells and its potential mechanisms.METHODS: MT was purified from the snake venom by using heparin agarose and Superdex75 chromatography.Mast cells were dispersed from human lung, colon and tonsil tissues after digestion with collagenase and hyaluronidase.The dispersed mast cells were then challenged with MT,stimulus and control in LP4 tubes for 15 min at 37 ℃.A glass fibre-based fluorometric assay was used to measure histamine in the supernatants of dispersed mast cells.RESULTS: MT induced a dose-dependent release of histamine from human colon,lung and tonsil mast cells.As low as 0.03(mg/L) of MT was able to stimulate significant histamine release from human colon mast cells,but a minimum of 0.3 or 30 mg/L of MT was required to stimulate a similar level of histamine release from lung or tonsil mast cells,respectively.The release of histamine from colon and lung mast cells in response to MT was maximized at 12 min following the addition of the stimulus.This was quite different from the picture of the peak histamine release from tonsil mast cells,in which histamine release was maximized at 8 min following the addition of MT.Pretreatment of cells with metabolic inhibitors and pertussis toxin reduced dramatically histamine release from human colon,lung and tonsil mast cells by MT.In exogenous Ca~(2+) and Mg~(2+) free experiments,the release of histamine induced by MT was significantly decreased.CONCLUSION: Cobra snake venom MT induces human mast cells to release histamine through a G-protein-related mechanism,which may contribute to the pathogenesis of venomous snake bite.

Objective To explore the effects of sodium ferulate injection on CTGF, MMP-9 and TIMP-I in the serum of the patients with idiopathic pulmonary fibrosis(IPF). Methods 46 cases with IPF were randomly divid-ed into control group of 20 eases and treatment group of 26 cases. Control group was given the usual treatment and the treatment group was given the usual treatment and sodium ferulate injection. The levels of CTGF, MMP-9 and TIMP-1 in the serum were measured before and after treatment. Results After treatment,the concentration of CTGF,MMP-9 and TIMP-1 in patients in the treatment group was significantly improved than that in the control group(P < 0.05). Conclusion The treatment with sodium ferulate injection could improve the IPF through improving the production of CTGF,MMP-9 and TIMP-1.

Objective To investigate the mechanism of therapeutic action of dexamethasone on asthmatic mice by detecting the levels of IL-25 and IFN-γ in bronchoalveolar lavage fluid (BALF). Methods Balb/c mice with SPF grade were randomly divided into normal control group, asthma group and dexamethasone group. Asthma group and dexamethasone group were sensitized and challenged with ovalbumin ( OVA) . Dexamethasone group was intraperitoneally injected with dexamethasone one hour before challenging. The mice were executed 24 hours after the last challenge, and the HE stained pathological sections of the right lung were made. Pathological sections of lung were observed. BALF in the left lung was also collected. The total white blood cell count and absolute eosinophile ( EOS) count were observed, and the percentage of EOS was calculated. The levels of IL-25 and IFN-γwere measured with ELISA, and correlation analyses were made. Results The counts of total white blood cell and EOS, and the percentage of EOS were significantly higher in the asthma group than in the normal control group and dexamethasone group (P<0. 05). No differences were found between the normal control group and dexamethasone group. The IL-25 level was higher in the asthma group than in the normal control group and dexamethasone group (P<0. 05), and its level in the dexamethasone group was also higher than that in the normal control group. The IFN-γlevel was lower in the asthma group than in the normal control group and dexamethasone group (P<0. 05), while there was no significant difference between the normal control group and dexamethasone group. IL-25 was negatively correlated with IFN-γin each group. Conclusion Part of the mechanisms of dexamethasone acting on asthma are related to its inhibition on the pulmonary inflammation and promotion on the expression of IFN-γ, and possible inhibition of IL-25 expression.

Objective: To establish the standardized management mode for emergent medicines of inpatient area based on JCI. Methods:The expiry verification data of emergent medicines in hospital wards were collected from 2013 to 2015. The number and the amount of emergent medicines expired in the last three months in each calendar month during the three years were analyzed, the exist-ing problems in the management mode were found out and gradually optimized using PDCA cycle. Results:From 2013 to 2015, the re-placement amount of emergent medicines expired in the next month was 3497. 37 yuan. The number of emergent medicines expired in current month was 62. A total of 420 times of emergent medicines didn' t meet the requires of expiry verification from 2013 to 2015. After the check-in form redesign for emergent medicines and the standardization of replacement process, the number of expired medi-cines in the rescue carts was reduced, and the validity and quantity of drugs in all the rescue vehicles could be clearly shown in the new form. Conclusion:The standardization of emergent medicine management model can guarantee the safety of emergent medicines used in patients.

Objective: To study the dosages of capsules commonly used in children to provide reference for the addition of capsule specification for children.Methods: According to the application situation of capsule dosages commonly used for the inpatients in one children's hospital from January 1, 2013 to September 1, 2016, and combined with the usage rates of various drugs with different dosages, the addition of the minimum dosage of capsules was proposed.Results: Totally 10 species of commonly used capsules were selected from the children's hospital, and among them, 4 ones met the requirements of clinics, and the other 8 ones needed the specification addition, including clostridium butyricum capsules (210 mg) and polysaccharide ferric complex capsules (25 mg).Conclusion: The existing capsule specification can not fully meet the clinical requirements in the children's hospital.Therefore, appropriate dosage adjustments are still needed.

Objective RNPC1 may act as an oncogene or suppressor gene in human tumors and its role in human renal cell carcinoma (RCC) remains unclear.The objective of this study was to investigate the role of RNPC1 in the development of RCC.Methods Over-expression of RNPC1 gene group (RNPC1 group) and short hairpin RNA interfering RNPC1 gene expression (shRNPC1 group) were respectively built in RCC CAKI-1 and CAKI-2.The blank control group (NC group) and negative control group (SCR group) were built as well.The qRT-PCR and western blot (WB) were used to detect the expression levels of RNPC1 mRNA and RNPC1 protein in RCC cells.Lentivirus infection was applied to establish stable expressed RCC cell lines of RNPC1 over-expression and interference.Detection was made on mRNA and protein expression levels in RNPC1 stable RCC cell lines.The effects of RNPC1 on cell proliferation, colony formation assay, migration, and invasion were detected by CCK-8 cell differentiation test, clone test, scratch test, and migration and invasion test.WB was applied to detect the change of protein expression in the EMT path of RNPC1 stable RCC cell lines and explore the molecular mechanism of RNPC1 effect on the biological function of RCC cells.Results The expression levels of RNPC1 mRNA and protein were found lower in shRNPC1 group than those in SCR group, while the expression levels of RNPC1 mRNA and protein in SCR group were higher than those NC group (P<0.05).The capability of proliferation in shRNPC1 group was stronger than that in SCR group, while the capability of proliferation in shRNPC1 group was weaker than that in NC group (P<0.05).The capabilities of cell migration and invasion were stronger in shRNPC1 group than those in SCR group, while the capabilities of cell migration and invasion in RNPC1 group were weaker than those in NC group (P<0.05).RNPC1 could inhibit the proliferation capability of RCC cells and might up-regulate the protein expression of E-cadherin and down-regulate the protein expression of β-catenin and vimentin, thus inhibiting EMT path and the capabilities of migration and invasion off RCC cells (P<0.05).Conclusion RNPC1 acts as a tumor suppressor in RCC and has the potential for the prediction of RCC prognosis.
