Journal of Chinese Physician 2015;17(4):516-518
Objective To investigate the relationships between serum inflammatory mediators and myocardial injury in rats with sepsis.Methods Thirty male Sprague Dawley (SD) rats were randomly divided into normal control group and sepsis (0,24,48,72 h) groups.The rats subjected to sepsis were induced with cecum ligation perforation (CLP).Tumor necrosis factor alpha (TNF-α),interleukin-6 (IL-6),cardiac troponin Ⅰ (cTnI) and B-type natriuretic peptide precursor (NT-proBNP) in the venous blood were measured at 0 h,24 h,48 h,and 72 h after CLP.The lactic acid (Lac) of the arterial blood,cardiac index (CI),acute physiology and chronic health evaluation (APACHE) Ⅱ score were also determined simultaneously.Results The levels of TNF-α,IL-6,cTnI,NT-proBNP,and Lac in sepsis (24 h,48 h,and 72 h) groups were significantly elevated compared to normal control and sepsis (0 h) group.In addition,the number of sepsis (24 h,48 h,and 72 h) groups progressively increased (P <0.05).Conclusions It existed a close relationship between serum inflammatory mediators and myocardial injury,and made myocardium damage after CLP.

Objective To evaluate the damaging degree of hepatic cell in the patients with hepatocirrhosis. Methods 25 cases of hepatocirrhosis and 13 eases of normal controls were performed the dynamic imaging with 99mTc-EHIDA.By the three compartmental model configurations,the time-activity curers of the liver cell,and the function indexes liver cell extraction and excretion were calculated.Results The peak time and mean residence time in the hepatocirrhosis group were higher than those in the normal controls(P<0.01).Compared to normal controls, the peak value,index of uptake,take slope,and excretion slope of the hepatocirrhosis were all lower(P<0.01).Con- clusion Liver cell imaging is a better method for reflecting the change of liver cell function,and may be used to analyse the degree of hepatocirrhosis.

Objective To explore the stress response and immune balance in patients with severe trauma hemorrhage after fluid resuscitation and to clarify the clinical effect of Propofol administered with continuous intravenous infusion pump on it.Methods With prospective,randomized and control analysis,54 patients treated with fluid resuscitation following severe trauma hemorrhage admitted from October 1st,2008 to December 1st,2009 were studied.Another 20 healthy volunteers were enrolled as control group (C group). Patients were randomly divided into:conventional treatment group (R group,n =27 ) and conventional therapy combined with propofol treatment ( P group,n =27) as per gender,age,ISS score,estimated blood loss four factors and the principle ofminimum distribution imbalance index.HR,MAP,the levels of stress hormones [ norepinephrine (NE),cortisol (Cor) ],immune function ( T lymphocyte subsets Th1/Th2) and other biomarkers were observed.Mortality within 28 d between R group and P group was compared.ANOVA was used for the comparison of biomarkers,and independent samples t test was employed to compare variables between the two groups. Results Plasma cortisol (Cor),norepinephrine (NE),alanine aminotransferase (ALT),creatinine ( Cr),blood glucose,and Th1 and Th2 lymphocytes in patients were significantly higher than those in healthy volunteers of group C (P <0.01 ),and Th1/Th2 was significantly lower than those in healthy volunteers of C group (P =0.001 ).The ALT (48 h),Glu (6 h),NE (24 h and 48 h) and Cor (6 h and 24 h) of patients in P group were lower than those in R group ( P <0.05 ),and Th1 and Th2 were lower than those in R group at different intervals ( Th1:24h P =0.028,48 hP=0.002 ; Th2:6 h P=0.033,24 h P=0.007,48 h P=0.009),and Th1/Th2 ratio (48 h) was significantly higher in P group than that in R group (P =0.028),but there was no significant difference in mortality within 28d between the two groups. Conclusions Strong stress response,immune suppression and organ dysfunction can occur in the early stages of severe trauma hemorrhage after fluid resuscitation.Propofol can inhibit excessive stress response,modulate the immune balance and protect the important organs in those exsanguination patients from severe trauma.

NAD +-dependent cytosolic glycerol-3-phosphate dehydrogenase in Sacch aromyces cerevisiae is one of the key enzymes in metabolic pathway of glycerol . catalysing the reduction of dihydroxyacetone phosphate to glycerol-3-phosph ate.It has two isoenzymes.To study the differences between their structures, their expression of encoding genes and their functions may help increase the understan ding of the cell response mechanism to the hyperosmotic and anoxic conditions. In this paper the research on the two isoenzymes was reviewed.

Objective To obtain recombinant human Smith D1 (Sm D1) antigen and establish detecting assay.Methods Human Smith D1 antigen was synthesized by PCR using human Leukemic cDNA. The prokaryotic expression vector pGEX-ST-Sm D1 was constructed and transformed into E.coli.BL21 cell.Protein expressed under the induction of IPTG.We established DIGFA for detecting anti-Sm D1 antibodies with purified Sm D1 antigens.Results Sequence and restriction analysis revealed Sm D1 gene was cloned in frame into pGEX-5T,SDS-PAGE profile showed a clear protein band with a relative molecular weight of 39 000 and western blotting indicated that the expressed product specifically reacted to polyclonal anti-human Sm D1 genes.There was no significant difference between DIGFA and IB.The agreement between DIGFA and IB was 91.7% as calculated by Kappa statistical method.The sensitivity and specificity of DIGFA were 100% and 83.3% repectively.Conclusions Human Sm D1 gene is successfully cloned、 expressed and purification.The DIGFA,using purified Sm D1 antigens,is as good as IB,rather simpler, more rapid and reliable assay.
