Objective To investigate the anti-inflammatory effect of peroxisome proliferator-activated receptor-γ(PPAR-γ)in non-obese diabetic mice(NOD mice)with Sj(o)gren's syndrome(SS)．Methods Twenty 8-weeks-old female NOD mice were randomly divided into 2 groups．Rosiglitazone and normal saline were administered for the rosiglitazone group and control group respectively．At age of 12 weeks and 15 weeks，one mouse in the rosiglitazone group and the control group were killed respectively,and the others were sacrificed at the age of 17 weeks．Blood were obtained by cardiac puncture，and minor salivary glands (MSG) were resected．The histopathological changes waere examined by H&E staining．The level of IL-1β，IL-4，IL-6 and TNF-α in serum were measured by ELISA．Real-time PCR waft used to evaluate the mRNA expression level of IL-1β，IL-4，IL-6 and TNF-α in MSG．Student's t-test was used to assess the differences．Results Compared with the control group，the mice in the rosiglitazone group showed that：①histopatho-logical change was significantly ameliorated．②At the age of 17 weeks，IL-6[(26±7)vs(37±11)，t=-2．298] and TNF-α[(57±22)vs(79±21)，t=-2．188] were expressed significantly lower and IL-4[(26±13)vs(12±4)，t=2．438 ] was expressed significantly higher in serum(P<0．05)．③The expression of TNF-αwas significantly decreased and the expression of IL-4 was significantly increased in MSG (P<0．05)．Conclusion PPAR-γ can ameliorate SS on NOD mice effectively．The mechanism may be related to reduction of Th1 cytokines，and the Th1/Th2 balance is changed into Th2 predominant．

BACKGROUND: Patients with acute stroke mostly receive treatment in the integrative hospital, but quite a large part of them were treated only with medication during the earlier stage.OBJECTIVE: To probe the influence of earlier integrative rehabilitations on emotions and daily life capability of patients with acute stroke with the outcomes compared with those unexposed to rehabilitative treatment.DESIGN: Randomized controlled study.SETTING: Neurological Department of a municipal Hospital.PARTICIPANTS: Eighty patients who received treatment due to the first onset of acute stroke of internal carotid system were selected from the Neurological Department of the First People's Hospital of Lianyungang City, Jiangshu Province between January 2002 and August 2003. Totally 51 males and 29 females aged (63.42±7.47) years were randomly divided into rehabilitation control group with 40 cases each.METHODS: Patients of the two groups received routine neurological medication in the hospital. When stroke was controlled, patients in the rehabilitative group (including patients with cerebral infarction who were hospitalized for less than 1 week and patients with cerebral hemorrhage who were hospitalized for less than 2 weeks) were subjected to rehabilitative treatment, including rehabilitative training of insulted limbs (physical treatment and/or exercise therapy), physical therapy, acupuncture and psychological consultation. Rehabilitative treatment was given 1-2 times a day and 45 minutes for each time. Physical therapy and acupuncture were given once a day and 20 minutes for each time. In contrast, patients in the control group were only asked in the doctor's round to do exercise themselves or with the assistance of others. Psychological states of all the patients were assessed with Symptom Self Rating Scale before treatment and discharge and daily life capability was also assessed with Barthel index (totally 10 items with scores of 0-15, full mark was 100, and patients who scored for ＜ 60were considered of self-incapability).MAIN OUTCOME MEASURES: Scores for symptom checklist (SCL)and Barthel index of the two groups before treatment and when patients were discharged.Scores for each symptom factors in SCL were significantly improved in the rehabilitation group when patients were discharged from the hospital (P ＜ 0.05-0.01), and somatization, obsessive-compulsive, depression, anxiety and psychoticism, etc. were also obviously improved in the control group (P ＜ 0.05); moreover scores for somatization, obsessive-compulsive,depression, anxiety phobic anxiety and psychoticism in the rehabilitation group after treatment were significantly lower than those in the control group [(1.55±0.43), (1.80±0.35); (1.48±0.39), (1.68±0.55); (1.54±0.43),(1.83±0.37); (1.32±0.39), (1.56±0.36); (1.46±0.43), (1.66±0.52); (1.12±0.38),creased aftertreatment (P ＜ 0.05-0.01), but those of the rehabilitation group were significantly higher than those of the control group [(73.24±4.64),(52.44±2.86), P ＜ 0.05].CONCLUSION:Scores for symptomatic factors in SCL and Barthel indexes were improved after treatment, especially in patients who received rehabilitative treatment, suggesting that earlier integrative rehabilitative treatment may play active influence on the emotions and daily life capability of patients following acute stroke.

Using metabolic flux balance model , the metabolic flux balance of L- v aline synthesis was established in this paper by material balances and linear p rogramming method. The analysis results indicate that 62.8% metabolic flux ent er ed EMP pathway and 38.2% metabolic flux entered the HMP pathway. And only 9.2 % c arbon entered the TCA cycle. But comparing to the optimal flux distributions of 92.31, the production of L-valine should be improved from the genetic manipula ti on and fermentation control through reducing byproduct of amino acid and decreas ing the metabolic flux.

OBJECTIVETo observe the inhibitory effect of gefitineb on the proliferation and its inducing effect on the apoptosis of mouse I-10 Leydig testicular cancer cells in vitro.

METHODSWe treated I-10 Leydig testicular cancer cells of mice with gefitineb at 0, 1.25, 2.5, 5, 10, 20, and 40 µmol/L. Then we determined the inhibitory effect of gefitineb on the growth of the cells by MTT, detected their early and late apoptosis by Annexin V-FITC/propidium iodide double staining and Hoechst 33258 nuclear staining, respectively, and observed the expressions of apoptosis-related proteins Bcl-2, Bax and caspase 3/9 by Western blot.

RESULTSCompared with the blank control group, gefitineb significantly inhibited the proliferation of the I-10 cells at 10 and 20 µmol/L (P < 0.05). The survival rate of the cells was (32.4 ± 2.8)% (P < 0.01) and their early and late apoptosis rates were (26.7 ± 4.2)% and (59.33 ± 10.2)% in the 40 µmol/L group, significantly different from those in the control (P < 0.05 and P <0.01). In comparison with the blank control group, gefitineb at 10, 20, and 40 µmol/L increased the expression of pro-apoptotic protein Bax by (41.9 ± 7.1), (60.1 ± 9.8), and (69.0 ± 11.3)% (all P < 0.05), decreased that of apoptosis-inhibitory protein Bcl-2 by (50.3 ± 8.9), (63.9 ± 6.9), and (88.7 ± 13.9)% (all P < 0.05), and elevated that of the cleft proteins caspase-3 by (69.0 ± 6.9)% (P < 0.05), (71.5 ± 8.1)% (P < 0.05), and (110.9 ± 14.2)% (P < 0.01) and caspase-9 by (51.8 ± 4.9), (54.7 ± 6.7), and (43.8 ± 11.8)% (all P < 0.05).

CONCLUSIONGefitineb can increase the cytotoxicity of I-10 Leydig testicular cancer cells of mice and induce their apoptosis via the mitochondria-mediated apoptosis signaling pathway.

Objective To verify the evaluation index system of clinical science and technology achievements, taking the evaluation of science and technology achievements in Guangdong province as a demonstration. Methods We specified the criteria for grading each index included in the evaluation index system that we proposed before. 5 experts in clinical medicine were invited to evaluate 20 achievements applying for the Award of Guangdong Science and Technology Achievements in 2010. The weighted sum of scores for each achievement was calculated and used for further analysis. The reliability and validation of the system were assessed. Results The Cronbach's ? coefficient of the index system was 0. 91, indicating good reliability. There were high correlation of each measure with the total score and their affiliated grade one index. The scores that the experts graded were correlated with the original results of evaluation (rs= 0. 71, P ＜0. 000 1), but there remained some inconsistence. Conclusion The demonstration based on investigation data indicates that the evaluation system is easy to handle and has satisfactory reliability and validation. It can be applied to the evaluation of science and technology achievements in clinical medicine.
