When the glomerular mesangial cells of rats were cultured in vitro at high glucose concentration,the activity of extraeellular signal-regulated kinase(ERK),the expression of transforming growth factor-?_1(TGF-?_1)mRNA and the content of typeⅣcollagen in the supematant were higher than those at normal glucose concentration.These effects were inhibited by fluvastatin.The results showed that the activation of ERK signal transduction pathways appeared to play a role in the onset and progression of diabetic nephropathy. Furthermore,fluvastatin could protect the kidney by inhibiting ERK signal transduction pathway and TGF-?_1 expression.

Objective To analyze the awareness on health among high school students and its influencing factors in Guangdong. Methods Multi-stage sampling and questionnairs "2009 health awareness survey of the Chinese citizens" developed by our Department of Health, were used. Data were analyzed by multivariate multilevel model under MLwinN 2.19 software. Results The mean scores on knowledge and ideas, behaviors and related skills among 1606 high school students of Guangdong province, were 69.08 ± 14.81,60.05 ± 16.85 and 74.99 ± 21.17 respectively. Three items on health showed that they all related to each other and relations between grades (0.972,0.715 and 0.855) were greater than the individuals (0.565,0.426 and 0.438). Conclusion Factors as students from outside the Pearl River Delta region or from the rural areas, being male, at general secondary schools, at grade one, with poor academic performance and more pocket money etc., had lower levels on those related information of health.

OBJECTIVETo observe the intervention effect of acupuncture on early onset of selec- tive serotonin reuptake inhibitors (SSRIs) in treating depressive disorder, and to study its effect on ser- um 5-HT and unbalanced inflammatory cytokines secreted by TH1/TH2.

METHODSTotally 90 patients with depressive disorder were randomly assigned to the drug control group (as the control group, 45 cases) and the acupuncture combined drug treatment group (as the treatment group, 45 cases). All patients were treated for 4 consecutive weeks. Another 45 healthy subjects were recruited as a healthy control group. The effect of acupuncture on early onset of SSRls in treating acute phase depressive disorder pa- tients was evaluated by HAMD score in the control group and the treatment group before treatment,and at weekends of the 1st, 2nd, and 4th week after treatment. Besides, their serum levels of 5-HT, IL-1β and IL-6 (secreted by TH1), and IL-4 and IL-10 (secreted by TH2) were detected before treatment and after treatment at the weekend of the 4th week.

RESULTSCompared with the healthy control group,serum lev- els of 5-HT, IL-4, and IL-10 decreased in the two drug-treated groups before treatment (P < 0.01); serum levels of IL-1β and IL-6 increased (P <0.01). Compared with before treatment in the same group, HAMD score decreased in the control group at weekends of the 2nd and the 4th week after treatment (P < 0.01); HAMD scores decreased in the treatment group at weekends of the 1st, 2nd, 3rd,and 4th week after treatment (P < 0.01); serum levels of 5-HT, IL-4, and IL-10 increased,serum levels of IL-1β and IL- 6 decreased in the two drug-treated groups after treatment (all P < 0.01). Compared with the control group at the same time point,HAMD scores decreased in the treatment group at weekends of the 1st, 2nd,3rd,and 4th week after treatment (P < 0.01),serum levels of 5-HT, IL-4, and IL-10 increased (P < 0.05, P < 0.01), serum levels of IL-6 decreased (P < 0. 01).

CONCLUSIONAcupuncture could accelerate early onset of SSRIs in treating acute phase depressive disorder, and effectively regulate serum 5-HT levels and inflammatory cytokines secreted by TH1/TH2.

OBJECTIVETo investigate HBV mutations in reverse transcriptase (RT) gene and precore/basal core promoter (PC/BCP) regions in a chronic hepatitis B patient and to analyze the link between the mutations and drug resistance or HBeAg sero-conversion.

METHODSEighteen serum samples were collected from a chronic hepatitis B patient during his 14 hospitalizations from June 2002 to September 2007. HBV DNA was extracted and nested PCR was employed for amplification of target gene fragments. Direct sequencing of PCR products was performed followed by analysis with NTI software. The significance of the results was analyzed in combination with the clinical data of the patient.

RESULTSSeveral mutations were identified in succession, including LAM-resistant mutations M204I/V and L180M+M204V, ETV-resistant mutation S202G, and HBeAg nonsense mutation G1896A. The results were in accordance with the disease progression of the patient.

CONCLUSIONSequencing of HBV RT and PC/BCP regions is valuable for comprehensively checking the viral mutations and thus it is helpful in the surveillance of patients in clinics as a way for adopting reasonable antiviral therapy.

Objective To investigate the relationship between bus drivers' personality characteristics with driving experience and to provide reference for safe driving. Methods A total of 158 bus drivers who work for one year and above were extracted by random sampling from a bus company in Ningbo during March 2016 to May 2016. The survey was carried out by 16 personality factor questionnaire (16PF), and compared with the national norm. Results The subjects were male, and average age was 39.24±6.78. The average bus driving year was 15.54±6.66 and mainly with high school education (62.66%) . The scores of agreeableness (9.21±3.18), intelligence (8.12±1.81), excitability (9.60± 3.26), excitement (10.84±4.59), suspicion (8.94±2.87), introversion (9.01±2.60), experiment (10.18±2.52) and independence (10.51±3.13) of the subjects were significantly lower than the national norm (P<0.05) . The scores of sensitivity (10.67±2.72), anxiety (9.60±3.78) and the self-discipline (13.30±2.42) were significantly higher than the national norm (P<0.05) . And 54.43% of bus drivers have high score in eight sub-personality analysis of mental health factors and 67.09% of them have low score in professional achievement factor. The analysis of personality characteristics of bus drivers with different bus driving experiences showed that the highest stability score was in 16 bus driving years and above, and the highest anxiety score was in 6~ <11 bus driving years and the highest tension and anxiety score were in 11 ~ <16 bus driving years (P <0.05) . Conclusion Bus drivers show special professional personality traits, and some characteristics will be strengthened and weakened with the growth of bus driving experience. It is necessary to carry out special training for the bus drivers with different bus driving experience, especially about dealing with various types of accident risk for new bus driver timely and psychological counseling for old bus driver regularly.

OBJECTIVETo explore the therapeutic effects and mechanisms of Zhubi capsule on adjuvant arthritis (AA) in rats.

METHODThe model of rat was induced by intradermal injection of CFA. The perimeter of ankle joint was measured at different time points. Con A-induced splencyte proliferation was examined by MIT assay and the expression of IL-1, IL-6 in synovium was determined by immunohistochemical method.

RESULTAfter the preventive administration of Zhubi capsule (5.2, 2.6, 1.3 g x kg x d(-1), x 25 d), it was found that Zhubi capsule significantly inhibited the primary and secondary ankle joint swelling. The increased Con A-induced splencyte proliferation reaction and the activated IL1, IL-6 expression of AA rat were suppressed by the treatment with Zhubi capsule.

CONCLUSIONZhubi capsule has a therapeutic effect on AA rats, and its mechanism is related to the immunoregulative function.

OBJECTIVESTo explore the effects of endotoxemia on gluconeogenesis in livers and kidneys during acute hepatic failure.

METHODTwenty-four healthy male SD rats were randomly divided into four groups (6 rats in each group) and all of them were injected intraperitoneally with solutions: group I with normal saline, group II with 400 mg/kg of D-galactosamine (D-GaLN), group III with 400 mg/kg of D-GaLN plus 50 microg/kg lipopolysaccharide(LPS), and group IV with 400 mg/kg of D-GaLN plus 500 microg/kg LPS. At 6 hours after the administration of different solutions intraperitoneally, blood samples were collected to examine blood urea nitrogen (BUN) and serum creatinine. Realtime PCR was used to study the expression of phosphoenolpyruvate carboxykinase (PEPCK) in the livers and kidneys.

RESULTSNo endotoxemia developed in group I or group II but it was evident in group III and group IV. The level of endotoxemia in group IV was higher than in group III (8.05+/-0.43, 3.50+/-2.25, P<0.05). After 6 hours of administration of LPS in group IV, hypoglycemia appeared, and blood glucose was normal in the other three groups. BUN and serum creatinine were all normal in the four groups, except that blood urea nitrogen was elevated in group IV. The mRNA of PEPCK in livers decreased gradually in all the four groups (2.54+/-1.32 vs 1.87+/-0.15 vs 0.91+/-0.13 vs 0.44+/-0.42, P<0.05). In the kidneys there was no change in the expression of PEPCK in group I and group II (0.75+/-0.03 and 0.77+/-0.04, P>0.05), but it increased in group III (0.75+/-0.03 vs 1.63+/-0.86, P<0.05), and decreased in group IV (0.75+/-0.03 vs 0.13+/-0.07, P<0.05).

CONCLUSIONDuring acute hepatic failure severe endotoxemia would damage the function of gluconeogenesis in livers and kidneys by inhibiting transcription of PEPCK and this can induce hypoglycemia.
