Objective To explore the mechanism of shengmai injection on relieving ischemia reperfusion injury and antagonizing systemic inflammatory response syndrome by regulating cytokines when it was applied at the early stage of cardiopulmonary resuscitation(CPR).Methods 40 cases suffering from cardiac arrest and had their heart beat recovered through CPR for more than 24 hours were randomly divided into SMI group and control group(20 cases for each).The patients in the two groups were treated with common therapeutics based on the CPR,but the patients in SMI group were intravenously dropped with SMI in the early period of PLS phase,then the changes of serum concentration of TNF-α and IL-81h,2h,6h,12h and24h after CPR in the two groups was compared.Results The concentrations of serum TNF-α and IL-8 stepped up gradually after resuscitation and the levels of TNF-αand IL-8 in SMI group were lower than that of the control group at 1h,2h,6h,12h and 24h after resuscitation(P＜0.05).Conclusion SMI functions to relieve ischemia reperfusion injury by regulating cytokines and antagonizing systemic inflammatory response syndrome.

Objective: To evaluate the feasibility of autoregressive integrated moving average with explanatory variables ( ARIMAX ) model including meteorological factors on the prediction of influenza-like illness ( ILI ), so as to provide a basis for the monitoring and early warning of influenza. Methods: The ILI data reported by four sentinel hospitals in Yuhang District of Hangzhou from the 1st week of 2014 to the 26th week of 2018 was collected, as well as the meteorological data during the same period. The ARIMAX model was established using the percentage of ILI cases in total outpatients ( ILI% ) data from the 1st week of 2014 to the 52nd week of 2017 and the meteorological factors selected by Lasso regression model. The ILI% from the 1st to 26th week of 2018 was predicted and compared with the actual values to verify the ARIMAX model. Results: From the 1st week of 2014 to the 26th week of 2018, a total of 60 419 cases of ILI were reported by the four sentinel hospitals of Yuhang District, with ILI% of 1.29%. Lasso regression analysis showed that there was a positive correlation between weekly average absolute humidity and ILI% ( r=27.769 ), and a negative correlation between weekly average temperature and ILI% ( r=-0.117 ). The ARIMAX (1, 0, 0) ( 1, 0, 0 )12 with weekly average temperature and absolute humidity was selected as the optimal model, with the Bayesian information criterion (BIC) value of 81.30 and the mean absolute percentage error (MAPE) value of 15.77%. The MAPE value of the ARIMAX model predicting the ILI% from 1st to 26th week of 2018 were 43.75%. Conclusion The ARIMAX model including meteorological factors can be used to predict the prevalence of ILI, but the accuracy needs to be promoted.

Objective To characterize the skin damage induced by ultraviolet radiation in officers was observed in 67.5% of the 1286 officers and soldiers:tanning in 62.05%(798/1286),photoaging in 18.66%(240/1286),polymorphous light eruption in 13.69%(176/1286)and sunbum in 13.30%(171/1286).Two hundred and thirteen subjects each had two kinds of skin amage,and 152 subjects each had three kinds of skin damage.With the time of being in the army and cumulative sun-exposure period,the prevalence of tanning,photoaging and polymorphous light eruption increased,while the prevalence of sunburn decreased.Sunburn mostly occurred in newly assigned soldiers.Conclusions The condition of skin damage nduced by ltraviolet radiation iS severe in officers and soldiers working in high altitude,and effective measures are warranted for the prevention and treatment of the skin damage.

Objective To detect the expression of nesprin-1 gene mRNA and protein and to localize the sub-cellular protein during the development of mouse heart.Methods Samples of embryonic heart tissue were collected from postnatal and adult mice on embryo 12.5 days(E12.5),E14.5,E16.5,and E18.5,respectively.Expression levels of nesprin-1 mRNA and protein and the protein sub-cellular location in samples of embryonic heart tissue from mice were detected by reverse transcriptase PCR,Western blot analysis and immunofluorescence at different time points.Results The expression level of nesprin-1 mRNA and protein in samples of embryonic heart tissue from postnatal and adult mice was measured on E12.5,E16.5 and E18.5,respectively,which increased with the development of mouse heart,reached it peak on E16.5 and E18.5.The lowest expression level of nesprin-1 mRNA and protein was found in adult mice.Immunofluorescence showed that nesprin-1 was distributed in nuclear envelope and in spaces around the nuclei.Conclusion nesprin-1 is dynamically expressed during the development of mouse heart,and highly expressed in the mature period of cardiac conduction system and cardiac muscle cells,indicating that it plays an important role in the development of cardiac conduction system and cardiac muscle cells.

Objective To investigate the differences in the biochemical and pathological features and therapeutic response between the elderly-onset autoimmune hepatitis (AIH) and young-onset AIH.Methods From October 2013 to November 2016,a total of 87 consecutive AIH patients diagnosed by liver biopsy were enrolled and divided into elderly-onset group (≥60 years) and the young-onset group (＜ 60 years).The biochemical and pathological features and therapeutic response of the two groups were compared.Mann Whitney test and chi square test were performed for statistical analysis.Results As AIH diagnosed,the proportion of liver cirrhosis detected by imaging examination of elderly-onset group and the young-onset group were 67.7％(21/31) and 35.7％(20/56),respectively,the former was higher than the latter,and the difference was statistically significant (X2 =8.214,P=0.004).The proportion of patients complicated with extrahepatic autoimmune diseases of the elderly-onset group was 9.7％ (3/31),which was lower than that of the young-onset group (28.6％,16/56),and the difference was statistically significant (X2 =4.173,P=0.041).The median levels of alanine aminotransferase (ALT) and albumin of the elderly-onset group were 50.0 U/L (22.0 U/L,193.0 U/L) and 34.8 g/L (31.3 g/L,40.5 g/L),which were lower than those of the young-onset group (146.0 U/L (43.8 U/L,390.5 U/L),39.4 g/L (35.8 g/L,44.6 g/L),and the differences were statistically significant (Z=-2.109,-2.092;both P＜ 0.05).Between the two groups,there was no statistically significant difference in inflammation grade,fibrosis stage,interface hepatitis,lymphoplasmacytic infiltration,positive rate of hepatocyte rosette pattern,positive rate of centrilobular necrosis and small bile duct injury (all P＞0.05).After treatment,among 17 patients of elderly-onset group,seven patients obtained biochemical remission and the median time to remission was 3.2 months;among 37 patients of young-onset group,18 patients (48.6％) obtained biochemical remission and the median time to remission was 2.3 months.There was no significant difference in the percentage of patients achieved biochemical remission and the median time between the two groups (both P＞0.05).Conclusion The percentage of complicated with extrahepatic autoimmune diseases of elderly-onset group is lower than that of young-onset group,which indicates that age-associated immune dysfunction may involve in the genesis and development of elderly-onset AIH.

Objective To study the risk values of glycosylated hemoglobin ( HbA1c) screening patients with diabetes mellitus(DM) and pre-diabetes(PreD) in different age and sex.Methods HbA1c results from10 840 in Taizhou Hospital in 2012 were retrospectively collected , and CHAID analysis of decision tree was used in preliminary hierarchy .Age was further divided into five groups according to the preliminary results , then one-way ANOVA and linear regression were utilized to determine the differences between age groups and the prediction intervals (PI) of HbA1c,respectively.The upper limit value of 95%PI of HbA1c was set as diabetes risk values ( DRVs).By comparison of the sensitivity of DM patients screening by DRVs in 1 889 cases whose HbA1c were between 6.0%to 6.5%and the upper limit value of traditional HbA1c reference intervals to verify the screening value ofDRVs .Then the DRVs of HbA1c were utilized to screen DM in the population whose HbA 1c is were 6.0%-6.5% in 2008,and followed their re-examination records toverify the screening value of the DRVs toin PreD patients. Results (1) On the basis of the initially root of decisiontree by age , the populationwas divided into 9 groups ( P =0.000, F =231.462).By calculatingthe 95% confidence interval(CI) of each group and merging reasonably,it was finally divided into 5 groups:20-30years,31-40years,41-50years,51-60years and >60years (F=434.342, P=0.000).(2)Using the method of linear regression , the 95% PI of HbA1c of the 5 groups showed as following:20-30 years, males 4.6%-5.9%, females 4.6%-5.9%.31-40 years, males 4.8%-6.0%, females 4.7%-6.0%.41-50 years, males 4.9%-6.2%, females 4.8%-6.1%.51-60 years, males 5.0%-6.3%, females 4.9%-6.2%.>60 years, males 5.1%-6.4%, females 5.0%-6.3%.The traditional HbA1c reference interval was4.8%-6.3%.(3) The screening sensitivity of DM by the upper limit value of traditional HbA1c reference interval and DRVs in group which HbA1c was between 6.0%-6.5% were 34.5%and 48.1%,respectively.(4) Reviewing of the group with HbA1c between 6.0%-6.5% and not diagnosed as DM in 2008, 49 hadnegative DM screening results by using the upper limit value of traditional HbA1c reference interval but were positive in our setting DRVs , and 13 have developed to DM now , which accounted for 26.5%.Conclusion HbA1c DRVs need to be set hierarchically between different age and sex groups as a supplement to the traditional reference interval , which has a great significance for the diagnosis and treatment of DM and also forthe screening and intervention of PreD patients.
