Objective To investigate the expression of glucose transporter 3(GLUT 3) transcription level at different ischemic time in rats' focal cerebral ischemic penumbra and core of cortices.Methods Focal ischemic models of middle cerebral artery occlusion (MCAO) in rats were made by inserting nylon surgical thread. Brain samples were harvested from ischemic penumbra and core of cortices. The change of GLUT 3 mRNA was assessed by RT PCR.Results GLUT 3 mRNA in the penumbra regions slightly increased at 3 h after ischemia, and reached a peak at 24 h, in 96h following ischemia it came back to the normal level. As for ischemic core regions, GLUT 3 mRNA had a short time increase at 3 h after ischemia, and then rapidly decrease to the low level. Conclusion GLUT 3 mRNA expression was notably up regulated in the penumbra regions after focal cerebral ischemia,it may be a protective reaction against ischemic injury.

【Objective】To observe the effect of Huangqi Sijunzi Decoction(HSD) combined with parenteral nutrition in promoting postoperative recovery of gastric cancer patients.【Methods】Eighty gastric cancer patients were randomized into two groups.On the 3rd day after operation,the two groups received parenteral nutrition,and the treatment group(group A) was given HSD additionally.The anal exsufflation time,incision infection rate,biochemical indexes and immune indexes of the two groups were observed.【Results】The anal exsufflation time was(2.40?0.33) days in the treatment group and(3.82?0.26) days in the control group,the difference being significant(P0.05).The increase of pre-albumin in the treatment group was obvious as compared with that in the control group(P0.05).The increase of immune indexes was not obvious in the control group(P

T were also detected in the controls.Conclusion Nephrotic syndrome may be associated with NPHS2 identified in children.

Objective:To investigate the attitude towards task -shifting of mental health among non -psychiat-ric physicians of general hospitals in Guangzhou and to provide evidence for continuing education model and health policy making .Methods:A cross-sectional study was implemented among 1363 participants of 17 general hospi-tals from December 2012 to April 2013 in Guangzhou.Results:Among 1363 participants, there were 941 (69.6%) approved the concept of mental health task shift .Factors of attitude to the concept of mental health task shift include work 8-10 h/day (β=0.404, P=0.006), practice qualification (β=-1.345, P=0.016), less than 10%physical diseases combined with psychological or mental problems in clinical work (β=-0 .452 , P=0.014), demand of training cost/time(β=-0.596, P =0.021), get ready (β=1.436, P <0.001) and have little preparation (β=0 .694 ,P<0 .001 ) preparation for treating mental disorders at present work ( recognition and treatment).The possibility of participants′attitude toward task -shifting mental health is positive the highest (71.0%), followed by neutral (25.5%) and negative (3.5%).Conclusions:Strengthening non -psychiatric physicians′support for mental health task shift with respect to policy and legal levels in general hospitals , improving their recognition and preparation of mental disorders , as well as developing targeted training and courses are the highest priority .

Objective To realize basic status of occupational exposure among medical postgraduates,and provide theoretical evidence for making occupational precaution measures.Methods Data about occupational exposure among medical postgraduates in a teaching hospital between January 2011 and December 2013 were analyzed retro-spectively.Results A total of 3 362 medical postgraduates were monitored,56 (1 .67%)sustained occupational ex-posure.The most common occupational exposure sites were left hand thumbs(n=15,26.79%),occupational expo-sure most frequently occurred during operation(n=29,51 .79%),a total of 40(71 .43%)occupational exposure oc-curred during the process of operation and invasive procedure,all were sharp injuries.46(82.14%)exposure sources were with bloodborne-transmitted diseases.Surgery students accounted for 66.07%(n =37)of students sustained occupational exposure,exposure rate in master’s candidates was higher than doctoral candidates(2.31 % vs 0.28%,χ2 =18.325,P <0.001 ).After timely treatment and preventive medication,none of the students were infected. Conclusion It is necessary to strengthen the occupational safety education for medical postgraduates,improve pre-caution awareness,standardize all kinds of procedures,and implement standard precaution;timely and effective treatment after exposure is important for reducing occupational injury among medical postgraduates.

Objective To examine mutations in the WT1 and PLCE1 gene in three Chinese families with autosomal recessive steroid-resistant nephrotic syndrome (SRNS) once mutations in NPHS2 had been excluded. Methods Peripheral blood samples were collected for genetic analysis from three probands of three Chinese families and their parents, and two probands' siblings, and 50 adult volunteers with normal urinalysis. Genomic DNA was isolated from peripheral blood leucocytes. Ten exons and exon-intron boundaries of WT1, and 31 exons and exon-intron boundaries of PLCE1 were amplified by polymerase chain reaction (PCR). Mutational analysis was performed by DNA sequencing directly and RFLP (restriction fragment length polymorphism) and/or PCR. Results No mutation in both WT1 and PLCE1 was identified in three probands from three Chinese families with autosomal recessive SRNS. However, three variants of WT1, 126C>T, ⅣS5-64A>G and 903A>G, and 13 variants of PLCE1, -134A>G, 810T>C, 960G>A, ⅣS11-28C>G, ⅣS15+26A>C, 4724G>C, ⅣS20+40C>T, ⅣS21+64G>A, ⅣS22-26T> A, 5320C>T, 5780A>G, ⅣS27+24A>G and ⅣS31 +48_49insT, were detected in three probands and some controls, indicating that all these variants were gene polymorphisms. WT1 polymorphism ⅣS5-64A>G, and PLCE1 polymorphism ⅣS22-26T>A were novel. Conclusion All the encoding exons and exon-intron boundaries of both WT1 and PLCE1 in three probands are examined, and no causative mutations in WT1 and PLCE1 axe found, suggesting that mutation in WT1 and PLCE1 genes is not a major cause of the Chinese families with autosomal recessive SRNS.

OBJECTIVE: To study the role of follicular helper T (Tfh) cells and galactose-deficient IgA1 (Gd-IgA1) in the pathogenesis of childhood Henoch-Schönlein purpura (HSP) and the correlation between them. METHODS: A total of 36 children with newly-diagnosed HSP were enrolled. They were divided into two groups: HSP nephritis (HSPN) group with 11 children and non-HSPN group with 25 children according to the presence or absence of HSPN. Another 15 children who underwent physical examination at the outpatient service were enrolled as the healthy control group. Flow cytometry was used to measure the proportion of Tfh cells (CD4CXCR5ICOS) in peripheral blood. ELISA was used to measure the levels of interleukin-21 (IL-21) and interleukin-6 (IL-6) in peripheral blood and the serum levels of IgA1 and Gd-IgA1. A Pearson correlation analysis was used to investigate the correlation of serum Gd-IgA1 concentration with Tfh cells and related factors expression in the children with HSP. RESULTS: Both the HSPN and non-HSPN groups had significantly higher proportion of Tfh cells and expression levels of IL-21 and IL-6 in peripheral blood than the healthy control group (P<0.05). The HSPN group had significant increases in the above indices compared with the non-HSPN group (P<0.05). Both the HSPN and non-HSPN groups had significantly higher serum levels of IgA1 and Gd-IgA1 than the healthy control group (P<0.05). The HSPN group had significantly higher serum levels of IgA1 and Gd-IgA1 than the non-HSPN group (P<0.05). In the children with HSP, serum Gd-IgA1 level was positively correlated with Tfh cells proportion and IL-21 and IL-6 levels (P<0.05). CONCLUSIONS Tfh cells and related cytokines and serum Gd-IgA1 are involved in the development of HSP/HSPN. Tfh cells may mediate the increased production of Gd-IgA1.
