Objective To learn the current capacity building of emergency response teams in Tianjin for the purpose of goals setting.Methods Health Emergency Capacity Questionnaire was issued to 89 secondary and above medical institutions and 19 CDCs in Tianjin.The form covered such items as basic institutional information, workforce makeup, emergency preparations, detection and early warning, emergency response, and summary/assessment.Data collected in the questionnaire were subject to descriptive and correlation analysis.Results Tianjin has scored an initial success in emergency medicine as evidenced in its emergency response mechanisms in place, elevated capacity in emergency medical rescue and disposal, and enhanced competence of emergency teams.Rooms of improvement however include insufficient professionalism and independence of health emergency, inadequate emergency commanding and decision making system functions, insufficient laboratory test capacity at district/county levels, and insufficient social involvement in health emergency.Conclusions Top-down design should be emphasized, health emergency response should be enhanced in terms of management and response planning system, while capacity building of the teams and long-term primary care emergency mechanism deserve higher attention.

This study was aimed to construct eukaryotic expression vectors carrying the small hairpin RNA (shRNA) targeting TRPC6 gene and investigate the effect of TRPC6 knockdown on puromucin aminonucleoside (PAN)-induced podocyte injury. Two DNA sequences containing the small hairpin structure targeting TRPC6 were designed, synthesized and then inserted into the green fluorescence protein (GFP)-contained plasmids (pGC) to establish the plasmids pGCsi-TRPC6A and pGCsi-TRPC6B. Plasmids expressing scrambled shRNA were used as negative control and named pGCsi-NC. These plasmids were transfected into a conditionally immortalized murine podocyte cell line by using liposome. Flow cytometry was used to examine the transfection efficiency. TRPC6 mRNA and protein expression levels were detected by RT-PCR and Western blotting. Cultured podocytes were divided into four groups: control group, PAN treatment group, PAN+TRPC6 shRNA transfected group and PAN+scrambled shRNA transfected group. The paracelluar permeability to BSA was evaluated by Millicell-PCF Inserts and cell viability was measured by the trypan blue assay. Immunofluorescent assay was used to observe the distribution of α-actinin-4 and α-tubulin. The results showed that the transfection efficiency of the shRNA expression vector was about 45%. Expression levels of TRPC6 mRNA and protein were downregulated after transfection with pGCsi-TRPC6A and pGCsi-TRPC6B. Knocking down TRPC6 gene could effectively reverse the PAN-induced increase in the paracelluar permeability to BSA. The distribution of α-actinin-4 and α-tubulin was disrupted after treatment with PAN, which was reversed by knocking down TRPC6 gene. It was concluded that knocking down TRPC6 gene could effectively prevent podocytes from the permeability increase induced by PAN, which may be related to the regulation of podocyte cytoskeleton.

Objective To understand the ability and level of emergency rescue at general hospitals in Tianjin city. Methods Such actions as formulating plans and examination forms, establishing assessment indicators and evaluation criteria, and simulation exercises were performed to evaluate the capacity of 28 general hospitals in terms of their organizational structure, emergency response, event reporting, and summary assessment. Results The emergency response assessment system consisted of 4 level-1 indicators, 19 level-2 indicators and 58 level-3 indicators. 28 hospitals were found high in their overall emergency response capacity, but some were found with setbacks. For example, the " organizational structure" scored the highest in 4 first-level indicators, up to 88. 91％ , while " incident report" scored the lowest, down to 67. 99％ . Among level-2 indicators, professional emergency professional procedures and initial reporting scored the lowest. Conclusions In order to further improve the ability of medical institutions to respond to emergency events, the hospitals are recommended to enhance their backup resources for emergency response, their staff′s awareness of first aid knowledge and first aid skills, as well as their timeliness of initial reports and the completeness of progress reports.

Objective To investigate the molecular mechanism of ALKBH5 reducing sepsis-induced myocardial dysfunction(SIMD).Methods The expression levels of ALKBH5 and TRAF1 in the blood of 50 SIMD patients and 50 healthy individuals were detected using reverse transcription fluorescence quantitative polymerase chain reaction(RT-qPCR),and the correlation between their expression levels was analyzed by person analysis;In vitro experiments,H9C2 myocardial cells were divided into 7 groups according to over expression of TARF1 and knockdown ALKBH5.The molecular mechanism of ALKBH5 targeting TRAF1 to regulate lipopolysaccharide(LPS)induced myocardial cell damage was studied through experiments such as CCK8,ELISA,and Western blot;In the in vivo experiment of rats,LPS induced rats were divided into 6 groups according to over expression of TARF1 and knockdown ALKBH5.Experimental methods such as colorimetry,ELISA,Western blot,HE staining,and immuno-histochemistry were used to study the mechanism of ALKBH5 targeting TRAF1 through NF-κB pathway in reduc-ing myocardial cell damage.Results The expression levels of ALKBH5 and TRAF 1 were downregulated in SIMD,and the Pearson analysis showed a positive correlation between them(P<0.001);In vitro experiments showed that overexpression of TRAF1 promotes cell proliferation,inhibits the expression of inflammatory factors and proteins involved in the NF-κB pathway,and knockdown ALKBH5 obtain the opposite resulst;In vivo experi-ments in rats showed that knockdown ALKBH5 promotes injury in cardiomyocytes,expression of inflammatory factors and NF-κB-related pathway proteins,and nuclear translocation of NF-κB p65 protein,but the overexpression of TRAF 1 yielded the opposite results.Conclusion ALKBH5 increases the stability of TRAF1 by reducing its meth-ylation,thereby inhibiting NF-κB pathway,thereby reducing SIMD.
