Objective To study the curative effect of noninvasive ventilation on the patients of acute serious bronchial asthma complicated with pneumothorax. Methods Forty patients were randomly assigned to receive BiPAP ventilation immediately after thoracic closing drainage, or nasal catheter oxygen inhalation after thoracic closing drainage. Results After 24-hour ventilation, the levels of PO_ 2, SO_ 2, PCO_ 2 and breath rate between two groups were of remarkable difference (P0.05). The level of PO_ 2, SO_ 2, PCO_ 2, and heart rate, respiratory rate of the BiPAP patients were of remarkable difference (P

With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

AIM: To study the role of TGF-?/Smad pathway in the development of renal fibrosis in diabetic nephropathy.METHODS: Rats were induced to diabetic nephropathy by using tail intravenous injection of STZ.The expression of TGF-?_1,Smad2/3 protein and mRNA in kidney were examined at 2,4,8 and 16 weeks after STZ induction.CTGF,collagen-Ⅲ,PAI-1 mRNA expression in kidney at 16 weeks of STZ-induced diabetic nephropathy and normal rats were studied by RT-PCR.RESULTS: Weak TGF-?_1,Smad2/3 protein were detected in normal renal tissues while strong TGF-?_1,Smad2/3 staining were observed in renal tissues of diabetic nephropathy(0.057?0.030/0.223?0.040;0.017?0.010/0.153?0.010,respectively,P

AIM:To investigate the changes of histone modifications during the activation of primarily cultured rat hepatic stellate cells ( HSCs) and the relationship between histone modification patterns andα-smooth muscle actin (α-SMA) expression, and to explore the roles of histone modifications in the activation of HSCs.METHODS:The rat HSCs were isolated by in situ perfusion of collagenase combined with density gradient centrifugation, cultured in vitro and identi-fied by immunofluorescence staining.The morphological features of the cells were observed under inverted microscope.The changes of desmin and α-SMA during the activation of HSCs were detected by immunofluorescence staining and Western blotting.The levels of histone 3 lysine 4 dimethylation (H3K4me2), histone 3 lysine 9 dimethylation (H3K9me2), his-tone 3 lysine 9 acetylation (acH3K9) and histone 4 lysine 12 acetylation (acH4K12) in quiescent HSCs and activated HSCs were determined by Western blotting.RESULTS: The morphology of HSCs shifted from a quiescent phenotype to highly activated myofibroblast during the culture.Immunofluorescence staining and Western blotting showed that the expres-sion levels of α-SMA and desmin were increased over time and reached maximum at 15 d.According to the results of cell morphology and immunofluorescence staining, the cells cultured for 24 h and 15 d were quiescent and activated HSCs, re-spectively.Compared with quiescent HSCs, there were higher H3K4me2 and lower H3K9me2, acH3K9 and acH4K12 modification levels in activated HSCs ( P<0.01 ) .CONCLUSION: Histone modifications show anomalous expression during the activation of primarily cultured rat HSCs.Histone modifications may contribute to the transdifferentiation of HSCs and the development of hepatic fibrosis.

Objective: This experiment was designed to study the change of nitric oxide (NO) content in different parts of brain in rats suffering from iodine deficiency(ID) and hypothyroidism since their fetal period. Methods: Iodine deficiency animal model was made and NO content in hippocampus(HPC), cerebellum (CE) and cortex(CO) were measured by using NO test kit. Results: Urinary iodine and serum T 3?T 4 concentrations significantly decreased and learning-memory capacity was impaired in ID rats. NO content was significantly lower in HPC and CE in ID rats than in control rats.(HPC:11.61?2.31/2.3?1 18 ?mol/g Prot;CE:10.77?5.16/4.70?1.95 ?mol/g Prot).No difference was found in cortex. Conclusion: Iodine deficiency and hypothyroidism since fetal period could affect NO level in rat brain. Different parts of brain have different sensitivity to ID and hypothyroidism.The changes of NO content in hippocampus may contribute to the learning-memory impairment in ID rats.

OBJECTIVE: To investigate the effect of miR-590-5p on the expression of lectin-like oxidized low density lipoprotein receptor 1 (LOX-1) in apoptotic human umbilical vein endothelial cells (HUVECs) induced by ox-LDL, and to explore the role of miR-590-5p in modulating HUVECs apoptosis. METHODS: HUVECs were exposed to ox-LDL (50 μg/mL) for 0 to 48 h. Apoptosis was detected by Annexin V-FITC stain and was distinguished from necrosis by propidium iodide (PI) staining. The relative expression level of miR-590-5p in HUVECs was analyzed using real-time quantitative PCR (RT-qPCR). HUVECs were transfected with miR-590-5p mimics or miRNA mimics control followed by 50 μg/mL ox-LDL stimulation for 48 h. LOX-1 mRNA and protein were measured by RT-qPCR and Western blot, and apoptosis in HUVECs was analyzed by flow ctyometry after Annexin V-FITC/PI double stain. RESULTS: Incubation of HUVECs with 50 μg/mL ox-LDL for 0 to 48 h resulted in a time-dependent induction of apoptotic cell death and down-regulation of miR-590-5p. Transfection of miR-590-5p mimics suppressed LOX-1 expression at both mRNA and protein levels, leading to a reduction of ox-LDL-induced apoptosis in HUVECs. CONCLUSION MiR-590-5p protects endothelial cells from ox-LDL induced apoptosis by inhibiting the expression of LOX-1.

Objective To determine the effects of histone deacetylase inhibitor suberoylanilide hydroxamic acid(SAHA) on the cell proliferation and apoptosis of the human hepatic stellate cell line LX-2.The possible underlying mechanisms were also investigated.Methods The LX-2 cells were treated with SAHA in vitro.The morphology of LX-2 cells in different concentrations groups was observed by inverted microscope;the proliferation of LX-2 cells was measured by MTT assay;the Annexin V-FITC and PI staining was used to detect the apoptosis of LX-2 cells by flow cytometry and fluorescence microscope;the expression of α-SMA,collagen Ⅰ,acH3K9,acH3K14 and acH3K18 were detected by Western blot.Results The morphology change of LX-2 cells showed that SAHA inhibited the proliferation rate of LX-2 cells and in a dose dependent manner(P<0.05).The LX-2 cells were sensitive to SAHA along with time increasing,and in a time-dependent manner(P<0.05).Western blot showed that the expression levels of α-SMA and collagen-Ⅰ were significantly lower(P<0.05),on the contrary,the acetylation levels of acH3K9,acH3K14 and acH3K18 were significantly higher (P<0.05).Conclusions The increased acetylation of the histone acH3K9,acH3K14,acH3K18 and the lower expressed α-SMA and collagen-Ⅰ in LX-2 cells may be one of the mechanisms of SAHA.
