Objective To investigate the protective effect of angiotensin converting enzyme inhibitor(ACEI) and angiotensin receptor antagonist(ARB) on renal function of type 2 diabetic nephropathy patients.Methods 60 patients with type 2 diabetic nephropathy and mild or midrange damages of renal function were observed.The patients all accepted routine diabetic therapy and were randomly divided into three groups,ACEI group,ARB group and combination group with ACEI and ARB.The blood pressure,blood creatinine and urine protein of 24 hours were measured before therapy and 8 weeks after therapy.Results The excretive amounts of urine protein decreased in all groups.The excretive levels of urine protein in combination group significantly decreased than in ACEI group and ARB group(P

Objective To investigate the expression and possible function of tumor susceptibility gene 101 (TSG101) in multidrug-resistant cell lines of gastric cancer.Methods The expression of TSG101 was examined in gastric cancer cell line SGC7901 and its vincristine(VCR)-resistant subline SGC7901/VCR with semi -quantitative RT-PCR and Western blot. TSG101 eukaryotic expression vector was transfected into SGC7901 cells by lipofectamine TM 2000. The expression levels of TSG101 in SGC7901 and the transfectants were detected with Western blot. Fluorescence-activated cell sorting was applied to examine the cell cycle alteration and the intracellular mean fluorescence intensity of adriamycin (ADR). Growth curve and drug sensitivity of cells to VCR and ADR were analyzed by MTT assay.Results TSG101 was highly expressed in VCR resistant gastric cancer cells. The expression of TSG101 in TSG101 transfectants was up-regulated compared with that in SGC7901 transfected with empty vector or in SGC7901 cells. TSG101 transfectants were accumulated in S phase, with a concomitant decrease of cell population in G 1 phase. MTT assay showed that TSG101 transfectants proliferated rapidly and were more resistant to VCR and ADR than control cells. Conclusions The over-expression of TSG101 could promote the multidrug resistance phenotype of sGC7901 cells. TSG101 may play a certain role in multidrug resistance of gastric cancer.

Objective To evaluate the prognostic role of bispectral index (BIS) monitoring in patients after cardiopulmonary resuscitation (CPR) in the intensive care unit (ICU).Methods Thirtythree adult patients after CPR were enrolled and divided into survived group and non - survived group as per 7-day survival.During their stay in the ICU,BIS and SaO2 (saturation of artery oxygen) levels of all the patients were continuously monitored.The neurological status of the patients was measured with Glasgow coma scale (GCS).Acute physiology and chronic health evaluation Ⅱ ( APACHE Ⅱ ) was used to evaluate the patient condition. SjO2 (saturation of jugular bulb venous oxygen ) levels of 23 patients were continuously monitored and then the difference in values between SaO2 and SjO2 was calculated to show oxygen metabolism in the brain. The studied variables were compared between the two groups. The correlations between BIS values and GCS scores,and between BIS and APACHE Ⅱ scores were respectively analyzed. Results The BIS values and difference in values between the SaO2 and SjO2 were significantly higher in the patients of survived group than those in the patients of non-survived group (P ＜0.01 ).There were positive correlation between BIS and GCS (r =0.821,P ＜ 0.01 ) and as well as positive correlation between BIS and APACHE- Ⅱ ( r =0.434,P ＜ 0.05 ).Conclusions The BIS may be useful to predict the post - resuscitative outcome of patients after cardiopulmonary resuscitation.

Objective:To study the relationship between emotional intelligence and coping efficacy of college students.Methods:220 college students in Guangdong province were selected as a sample to complete Emotional Intelligence Questionnaire and Coping Efficacy Scale.Results:①In the Emotional intelligence scores,the lower-grade students were higher than the higher-grade;cadre students were higher than the non-cadre students.②In the Coping efficacy scores,cadre students were higher than the non-cadre students'.③Emotional intelligence was positively correlated with coping efficacy,and competence perception;self-confidence degree and cognition level were mainly contributed to emotional intelligence.Conclusion:Emotional intelligence is positively correlated with coping efficacy.

Objective To pay attention to screening family disease and gene examination in patient with congenital adrenal hyperplasia (CAH). Method In this study, we investigated clinical data and performed gene sequencing of the pedigree and his family members with CAH. Results Based on clinical data, 3 of 6 family members were diagnosed CAH. Bone age of two boys nearly reach the maximum value. Genetic sequencing result indicated a T>A mutation of 1 004 position in CYP21A2 gene, which induced protein change I172N. Conclusion Disease screening and gene examine should be actively executed in patient with CAH in order to obtain diagnosis and start treatment as early as possible.

1.0～(?)1.5 cm(14.81%)(P=0.10).There was no lymph node metastasis in tumors less than 1.0 cm in diameter. The 5-year survival rates for cases with or without lymph node involvement were 92.31% and 60.0%,respectively,the difference was significant(P=0.000).The 5-year survival rates of 12 patients showing ground-glass opacity(GGO)on chest CT was 91.67% without any lymph node involvement.Conclusions:There is mediastinal and hilar lymph node involvement even with tumor diameter less than 2 cm.The results of the present study suggested that routine lymph node dissection is necessary even for cases with tumor diameter less than 2 cm.However,if the tumor is within 1.0 cm in diameter with obvious GGO showing on chest CT,these are good candidates for partial resection without mediastinal lymph node dissection.

The paper is to report the establishment of a method for quickly evaluating compatibility of Chinese medicines injections. Isothermal titration calorimetry (ITC) was used to evaluate compatibility of Yiqifumai (YQFM) and vitamin C injection (Vc)/5% glucose injection (5% GS). The diversification of Gibbs free energy (deltaG), enthalpy (deltaH) and entropy (deltaS) were used to decide reaction types of colliquefaction procedures of different injections. The reactive profiles were used to determine signs and quantity of heat. And high performance liquid chromatography (HPLC) was used as a supportive method for ITC. Then, feasible binding sites were analyzed based on the information of spatial structures of major compositions. During the colliquefaction procedure of YQFM and Vc, [deltaH] > T[deltaS], so, the reaction is enthalpy-driving. And the reactive profile showed that a big deal of heat was given out during the procedure. Obviously, chemical reactions happened and the major compositions changed. On the other side, the reaction of YQFM mixed with 5% GS was entropy-driving, because [deltaH] < T[deltaS]. The reactive profile showed there was a little heat gave out. So, non-chemical reactions happened, and the major compositions did not change. The conformity existed between the results of ITC and HPLC. ITC could be used to evaluate the compatibility of Chinese medicines injections because of the advantages of ITC, such as real time, fast, sensitive and having more parameters.

Phospholipase D(PLD) is ubiquitous in bacteria,fungi,and mammal.In pathogenic microorganisms,PLD can be pathogenic determinant and play a role in spore generation.In mammalian cells,PLD functions in several signal transduction pathways,such as membrane transportation,mitosis regulation,and actin cytoskeleton regulation.In the process of pathogens invasion host cells,both of the pathogen and host cells’ PLD will be activated and a series of cascade reaction will be generated.During this process,pathogen’s PLD can regulate the polymerization and reorganization of its own actin filaments and induce the polymerization or reorganization of the host cell actin filaments near the foci,thus to promote the phagocytosis of the pathogen by host cell.Investigating the role of PLD activation in the infection will be significance for further understanding the molecular mechanism of pathogen-host cell interaction.

The genome of a new SV40 strain(SV-IMB)isolated from a rhesus monkey was completely sequenced and compared with other isolates.The results showed that the whole genome contains 5246bp,and the average identity of SV-IMB was 98.1% as compared to other SV40 isolates.Its regulatory region is composed of a complete enhancer and a defective enhancer.Amino acid changes occurred to some extent in both the large T antigen (T-Ag) and VP1 region.The findings demonstrate that the SV-IMB is a new SV40 isolate.
