AIM: To investigate the change of long-term potentiation ( LTP ) , and the expression of 5-hydroxytryptamine 1A receptor (5-HT1A receptor) and postsynaptic density protein 95 (PSD-95) in the hippocampus of the rats with posttraumatic stress disorder (PTSD), and to explore the mechanism of 5-HT1A receptor in the regulation of spatial memory in the PTSD rats.METHODS:Healthy adult SD rats (n=36) were randomly divided into control group and mod-el group, with 18 rats in each group.The rats in model group were treated with single prolonged stress to construct the mod-el of PTSD.Morris water maze ( MWM) was used to test the learning and memory ability .The LTP induced by high-fre-quency stimulation (HFS) was detected by electrophysiological method .The protein expression of 5-HT1A receptor and PSD-95 in the hippocampus was determined by Western blot and immunofluorescence .RESULTS: The MWM analysis showed that the latency of the rats searching for the underwater platform in model group was significantly longer than that in control group (P<0.01).The results of electrophysiological analysis showed that the amplitude of the evoked potential in both groups were significantly increased after HFS in the hippocampus , but that in model group was significantly lower than that in control group (P<0.01).The results of Western blot and immunofluorescence analysis showed that compared with control group, the protein expression of 5-HT1A receptor was obviously increased (P<0.05), while the expression of PSD-95 was obviously decreased in model group (P<0.05).CONCLUSION:The spatial memory impairment in the PTSD rats may be associated with the increase in the expression of 5-HT1A receptor and the decrease in the expression of PSD-95 in the CA1 region of hippocampus .

To examine the protective action and therapeutic effect of anisodamine on acute lung injure and its molecular mechanism,63 rats were randomly divided into three groups :normal control group(NS),lipopolysaccharide (LPS) group and anisodamine (ADM) group.Rat model of acute lung injure(ALI) was produced by injecting LPS(5mg/kg) into the tail vein.The lung index(LI),WBC count,the percentage of polymorphonuclear leukocyte(PMN) in the bronchoalveolar lavage fluid(BALF) were observed at 0,1,3,5 hours(T 0,T 1,T 2,T 3).The concentration of TNF-? were measured both in BALF and plasma at four time points.The expression of P65 was analyzed by immunohistochmical method five hours after injecting LPS.The results showed that LI of ADM group were significantly lower than that of LPS group at T 2 after injecting LPS(P

OBJECTIVETo verify the clinical efficacy on chronic fatigue syndrome of qi deficiency syndrome treated with acupuncture at selective time and explore the effect mechanism.

METHODSEighty patients were randomized into a selective-time-acupuncture group and an acupuncture group, 40 cases in each one. Qihai (CV 6), Guanyuan (CV 4), Hegu (LI 4), Taichong (LR 3), Sanyinjiao (SP 6) and Zusanli (ST 36) were selected in the two groups. In the selective-time-acupuncture group, acupuncture was used at 9:00am to 11:00am. In the acupuncture group, acupuncture was used at any time except in the range from 9:00am to 11:00am. No any manipulation was applied after the arrival of needling sensation. The treatment was given once every day, 10 day treatment made one session and two sessions of treatment were required. The fatigue scale was adopted to evaluate the efficacy before and after treatment in the patients of the two groups. The ratios among CD3+, CD4+ and CD8+ T cells in the peripheral blood were detected before ad b a after treatment.

RESULTSIn the acupuncture group, the total score of fatigue and the score of physical fatigue were reduced after treatment as compared with those before treatment (all P<0.05). In the selective-time -acupuncture group, the total score of fatigue, the s core of physical fatigue and the score of mental fatigue after treatment were reduced obviously as compared with those hefore treatment (all P<0. 01). The improvements in the scores of the selective-time-acupuncture group were superior to the acupuncture group (all P<0. 05). The ratio of CD3+ and CD8+ T cells was increased obviously after treatment in the two groups (all P<0. 05) and the ratio of CD4+ and CD8+ T cells was reduced obviously in the selective-time-acupuncture group (P<0. 05), which was better than that in the acupuncture group (all P<0.05). The total effective rate was 95.0% (38/40) in the selective-time-acupuncture group, which was better than 80.0% (32/40) in the acupuncture group (P<0.05).

CONCLUSIONThe acupuncture therapy at selective time is effective in the treatment of chronic fatigue syndrome of qi deficiency syndrome, which is especially better at relieving mental fatigue. The effect of this therapy is achieved probably by improving the immune function via the regulation of the ratios among CD3+, CD4+ and CD8+ T cells.

Objective:To study the solubility of repaglinide in meglumine aqueous solution. Methods: In order to increase the solubility of repaglinide, meglumine was used to react with repaglinide and obtain a molecular complex. The structure and composition of meglumine-repaglinide complex was analyzed by DSC, HPLC and HPLC-MS. Results:Meglumine and repaglinide formed a molecu-lar complex, and their best molar ratio was 1 ∶1. With the concentration increase of meglumine, the solubility of repaglinide also in-creased. The stability of molecular complexes decreased with the temperature increase. Conclusion:Meglumine plays a good role in the solubilization of repaglinide.
