The study was proceeded on the mRNA expression of the GULT1 and GLUT4 gene in the alloxan diabetic rats by the technique of dot-blot hybridization analysis. The results showed that the levels of the GLUT4 mRNA expression were reduced in diabetic rats while increased in insulin treated diabetic rats. This suggests that the reduced GLUT4 mRNA expression which could affect the quantity of its posttranslational products may be one of the causes of the insulin resistance.

Postoperative pulmonary dysfunction in patients undergoing cardiopulmonary bypass(CPB) is a significant clinical problem and has long been recognized by cardiac surgeons. The studies of the pathogenesis and protection strategies of CPB induced lung injury have been the focus in the field of cardiac surgery. This review presents the recent progress of the pathogenesis and protection strategies of lung injury following CPB.

Acute lung injury (ALI) is one of the most important complications after cardiopulmonary bypass (CPB) and the complex pathophysiology remains to be resolved incomplete. At present, there is no specific and uniform criterion about the diagnosis of ALI following CPB. The changes of physiology and biochemistry in the lung can indicate the development of the ALI, and give proof of the early diagnosis of ALI following CPB.

Objective To investigate if apoptosis induced by arsenic trioxide(As_2O_3)on bladder cancer T24 cell line is related to the alteration of protein kinase C and cyclic adenosine monophosphate (PKC-cAMP)and its possible mechanism.Methods Apoptosis was studied by TUNEL method.Radio- immunoassay and enzyme immunoassay methods were used to detect the PKC-cAMP alteration in apoptotic process.The expressions and activation of caspase3 were observed by immunocytochemical method and Western blot.Results Atter 24-h drug treatment,the cell apoptosis induced by different concentrations of As_2O_3 was detected by TUNEL method.In control group,the apoptosis rate was 0.86%;PKC level was 2.55 pmol?min~(-1)??g~(-1);cAMP concentration was 22.56 pmol/ml;the expression rate of caspase3 was 8.01%.Compared with control group,the apoptosis rates of 5?mol/L and 10?mol/L As_2O_3 groups increased 8.51-fold and 13.33-fold,respectively;PKC Level decreased 59.22% and 64.71%,respectively;cAMP in- creased 5.34-fold and 4.23-fold,respectively;expression rates of caspase3 increased 3.96-fold and 6.76- fold,respectively.The differences were significant(P＜0.05).Compared with As_2O_3 groups,apoptosis rates of 5?mol/L and 10?mol/L As_2O_3+100nmol/L phorbol 12-myristate 13-aectate(PMA)groups decreased 40.22% and 45.58%,respectively;PKC increased 1.00-fold and 0.76-told,respectively;cAMP decreased 8.37% and 31.46%,respectively;expression rates of caspase3 decreased 51.09% and 65.03%,respective- ly.Activation of caspase3 was detected in As_2O_3-treated groups and As_2O_3+100 nmol/L PMA-treated groups;and activations of caspase3 in PMA-treated groups were weaker than those in As_2O_3-treated groups. Conclusions The antitumor mechanism of As_2O_3 may be the induction of bladder cancer T24 cell apopto- sis by decreasing PKC and increasing cAMP level.

Different routes of surgical nutrition have different influences on physical immunity.Total parenteral nutrition (TPN) for a long time may inhibit immune function. Enteral nutrition (EN) may maintain integrity of structure and function of intestinal mucosa, prevent bacterial translocation, lighten systematic inflammatory response and improve immune function. This article reviewed the regulation of parenteral nutrition (PN) and EN to immunity and the application of immune enhanced nutrition.

Objective To evaluate the clinical efficacy of tigecycline combinated with isepamicin for treatment of pneumonia caused by multidrug-resistant Acinetobacter baumannii.Methods A retrospective analysis was performed in adult patients with multidrug-resistant Acinetobacter baumannii pneumonia in two general hospitals from January 2012 to January 2014.Total eighty-four patients with MDR-Acinetobacter baumannii pneumonia were randomly divided into two groups(n=42).One group was treated with tigecycline combinated with isepamicin(termed combination therapy group),and another group was administrated with cefoperazone sulbactam (termed control group ).The clinical cure rates,microbiological eradication rates and adverse events were collected and compared. Results There was no difference in APACHEⅡ score between two groups.The clinical cure rates in combination therapy group was significantly higher than that in control group(88% vs 61%,P<0.05),and with a higher rate of microbiological eradication(59.5% vs 35.7%,P <0.05 ).However,the occurence rate of adverse events was similar in the two groups (7.1% vs 1 1.9%). Conclusion With a higher rate of clinical efficacy and a lower rate of adverse events,the combination therapy with tigecycline and isepamicin would be a promising alternative for treatment with MDR-Acinetobacter baumannii pneumonia.

Objective To observe the effect of Danshen injection combined with ulinastatin on the brain protection and inflammatory reaction in patients with Severe traumatic brain injury.Methods 83 cases of patient with Severe traumatic brain injury were randomly divided into the observation group(43 cases)and the control group(40 cases).The control group was given ulinastatin based on conventional treatment,and the observation group was given Danshen injection and ulinastatin based on the control group.For 10 days,the differences of hemodynamic parameters(Qmean、Zc、DR)and serum nerve function indexes(β-EP、DynAl-13、NSE),inflammatory factors(IL-1,IL-6,TNF-α,CRP)between the two groups were be compared.Results ①Comparison of hemodynamic parameters There was significantly difference of Qmean、Zc、DR in these two groups(Fgroup=6.126,5.024,5.621,P<0.05),Qmean was showed a rising trend over time and Zc、DR were showed a declining trend over time(Ftime=10.146,9.247,9.381,P<0.05),the changed amplitude in observation group was higher than the control group(Finteraction=5.357,4.257,4.813,P<0.05); Comparison of nerve function indexes There was significantly difference of β-EP、DynAl-13、NSE in these two groups(Fgroup=5.827,6.294,6.731,P<0.05),they was all showed a reducing trend over time(Ftime=12.613,11.746,9.842,P<0.05),the declined amplitude in observation group was higher than the control group(Finteraction=6.353,7.251,4.284,P<0.05);Comparison of inflammatory factors There was significantly difference of IL-1,IL-6,TNF-α,CRP in these two groups(Fgroup=4.284,5.162,6.174,4.291,P<0.05),they was all showed a rising then reducing trend over time(Ftime=9.163,10.357,13.457,12.434,P<0.05),the changed amplitude in observation group was higher than the control group(Finteraction=4.255,5.242,8.530,7.847,P<0.05).Conclusion Danshen injection combined with ulinastatin has more obviously function of protecting the cerebralfunction and suppressing inflammation in the treatment of Severe traumatic brain injury compared with ulinastatin alone.

5-fluorouracil (5-Fu) as an antimetabolite drug,has been widely used in the treatment of various solid tumors.However, due to the heterogeneity of tumor and the impact of the individual, some patients still have drug resistance or serious lethal toxicity reaction.The text focuses on the research progress of pharmacogenomics and pharmacogenetics of some forecast elements which affect the efficacy and toxicity of 5-Fu,and discussed their guiding role on the choice of chemotherapy drugs.

Hepatic fibrosis is a wound healing response to liver injury. Activated hepatic cell is thekey evidence in the pathological fibrosis,which results in synthesis of large quantities of extracellular matrix components. Cytokines secreted mostly by activated Kupffer cell were remarkabe factors which have been proposed to stimulate and inhibit the fibrosis process.The close relationship between hepatic fibrosis and cytokines has been investigated. The article summarizes some important cytokines and the cytokines which can be used as target of antifibrotic therapy.
