Objectives　To investigate the effect of nitric oxide(NO) on hepatic steatosis caused by total parenteral nutrition(TPN) in rats.Methods　Thirty Wistar rats were randomly divided into five groups: Group A,normal control; Group B,TPN group;Group C,TPN plus L-arginine; Group D,TPN plus NG-nitrio-L-arginine methyl ester(L-NAME，NOS inhibitor); Group E,TPN plus L-arginine and L-NAME.At the seventh day,liver function tests were performed and the livers were resected to test the lipid and nitric oxide content,and nitric oxide synthase activity.Results　The hepatic lipid content 〔triglycerid(μmol/g),cholesterol(μmol/g)〕in group B significantly increased compared with group A （39.3±2.4、13.1±1.1 vs.6.9±0.8、5.6±0.6）(P＜0.05).That was higher in group D（49.7±6.2、14.1±1.7）than in group B(P＜0.05),whereas that was lower in group C（18.2±4.4、7.3±3.1）than in group B(P＜0.05).The activity and distribution of NOS in the liver were associated with the content and distribution of hepatic lipid.Conclusions　NO produced by the liver may protect hepatic steatosis caused by total parenteral nutrition in rats.

Anhedonia, or markedly diminished interest or pleas-ure, is a hallmark symptom of depression.As a psychopathological symptom, anhedonia was first noted in the early 19th century.The neurobiological mechanisms that underline anhedonia and its role in diagnosing depression disorder or evaluating antidepressant response have long been aroused attention for nearly a century.Consequently, there are many measuring methods established in both the animal study and human research, which would be reviewed in the present study.

Objective To explore the clinical significance of platelet count, C-reaction protein and D-dimer in Kawasaki disease children with coronary artery lesion. Methods 54 cases of children with KD treated in our hospital from January 2013 to December 2015 were divided into coronary artery injury (CAL) group (n=15) and without coronary artery injury (NCAL) group (n=39), according to the cardiac ultrasound examination. The relationship between the changes of platelet count, C reactive protein and D- two and coronary artery lesion in the 2 groups of acute and convalescent stages were detected. Platelet count, C-reaction protein and D-dimer of 54 healthy children were measured as a control. Results The levels of the platelet count, C-reaction protein and D-dimer of the KD children during acute stage are significantly higher than the control group (P<0.05), while the levels of C-reaction protein and D-dimer of the KD children during recovery stage was significantly decreased after treatment (P<0.05), the platelet count is remarkably increased (P<0.01). The platelet count, C-reaction protein and D-dimer for the KD children with coronary artery malformation, either at acute stage or recovery stage, compared with the control group were significantly different (P<0.05), with statistical significance. Conclusion The changes of the platelet count, C-reaction protein and D-dimer levels have close relations with the cardiovascular damage to the KD children.

Ojective To evaluate the therapeutic effects of fibrin glue for hemostases and preventing gastroenterologic tract leakage. Methods Fibrin glue was used to prevent bleeding or leakage of anastomotic stoma in 153 patients undrgone operation as compared with the control group. Results Postoperative hemorrhage in the experimental group reduced significantly (P

OBJECTIVE:To evaluate the clinical efficacy and safety of guaifenesin,pseudoephedrine hydrochloride- codeine phosphate oral solution in relieving cough,eliminating phlegm,relieving nasal stuffiness and other cold symptoms. METHODS:A total of 240 patients with cold symptoms(120 cases in trial group and another 120 cases in control group) were enrolled in our multicenter,randomized,double-blinded and parallel controlled study and treated with guaifenesin-pseudoephedrine hydrochloride-codeine phosphate oral solutionI or compound codeine phosphate liquor 10mL tid for(5?2)d.RESULTS:227(112 in trial group and 115 in control group) were the valid cases with completed trial.Compared with pre-treatment,both of the 2 groups had a significant improvement in symptoms including cough,expectoration and nasal stuffiness after treatment(P

Objective To investigate the expression and clinical significance of ABCG2 protein in hepato-cellular carcinoma (HCC). Methods Specimens of HCC were collected at The First Aifiliated Hospital of Sun Yat-sen University from January 2005 to December 2006. The expression of ABCG2 protein in 165 samples of HCC tissue, 25 samples of normal liver tissue and 40 samples of cirrhotic liver tissue was detected using immunohisto-chemistry. The correlation between the expression of ABCG2 protein and clinicopathological characters was then analyzed. Enumeration data, survival rate and the difference between groups were analyzed with a chi-square test, the Kaplan-Meier method and Log-rank test, respectively. Results ABCG2 protein expression was weakly posi-tive in all normal and cirrhotic liver tissues. In HCC tissues, the expression of ABCG2 protein was strongly positive in 66 cases and weakly positive in 99 cases. The expression of ABCG2 protein was related to tumor diameter, tumor number, adjacent organ invasion and TNM stages (χ2 =8. 130, 14. 279, 4. 820, 21. 179, P <0. 05). Kaplan-Meier survival analysis revealed that patients with strongly positive ABCG2 protein had a significantly lower 3-year overall survival (24. 1%) compared with those with weakly positive ABCG2 protein (39. 4%) (χ2 = 15.716, P<0.05). Conclusions The expression level of ABCG2 protein is related to tumor invasiveness, TNM stage and prognosis. ABCG2 has the potential to become a new target for HCC treatment.

Objective To discuss the effect of different methods of dropping the high temperature of the tubercular meningitis patients. Methods 35 cases with tubercular meningitis with high fever were divided into research group(11 cases) and control group(24 cases) ,24 patients in control group were treated by traditional cooling method, 11 patients in research group were rteated by mild hypothermia therapy, The self signs, the intracranial pressure,Glasgow scores, complications and the death rates of patients were assessed and compared. Results The effective rates of the research and control cooling method were 81.8% and 41.7% respectively. The difference between the two groups was significant;After the intervention,compared with the control group, the self scale is superior in research group,and the intracranial pressure and the death rates of patients were lower,and patients'Glasgow scores were higher,but the complications between the two groups had no significant differences. Conclusion Mild hypothermia can effectively control patients'temperature,at the same time, which can improve the patients conscious state and reduce the mortality.

Objective To separate the CD133 + subpopulation in human hepatocellular carcinoma (HCC) and investigate the tumorigenicity.Methods The human liver cancer tissues were subcutaneously transplanted into nude mice to generate xenograft tumors which were then isolated to prepare single cell suspension.The expression of CD133 + subpopulation was further detected using flow cytometry.The CD133 + subpopulations were separated and depurated with magnetic-activated cell sorting system.Immunofluorescence was performed to identify the histological phenotype of CD133 + subpopulation.The in vitro and in vivo clone formation assay and in vivo xenograft formation assay were performed, respectively.Results Flow cytometry analysis revealed that a percentage of (4.1 ± 0.6) ％ CD133 + cells were detected in xenografts.Immunofluorescence studies showed that (86.8 ± 7.5) ％ of the isolated cells were CD133 +.Compared with CD133-population, CD133 + cells showed a higher capability to generate clone sphere in vitro and a higher tumorigenicity in nude mice (P ＜ 0.05).Conclusion The CD133 + subpopulation in human hepatocellular carcinoma had a potent tumorigenicity and was enriched in cancer stem cells.
