OBJECTIVE:To study the effects of rosiglitazone(RH)on body weight,FPG,FFA and other indicators in diabe-tes model rabbit. METHODS:18 rabbits were evenly randomized into control group,model group and dextran group. The latter 2 groups were given alloxan intravenously to induce diabetes model. 3 groups were given RH(0.5 mg/kg)intragastrically,and dex-tran group was additionally given dextran 40 glucose injection(5 ml/kg)intravenously,once a day,for consecutive 3 weeks. Body weight,serum level of FPG,FFA,AngⅡ and NO were determined before and after medication. RESULTS:Compared with be-fore medication,body weight of rabbits in control group were increased after medication,while the levels of FFA and AngⅡ were decreased;the levels of FPG and FFA were decreased in model group;body weight of rabbits were decreased in dextran group af-ter medication,with statistical significance (P<0.01 or P<0.05);other indicators had no statistically significant difference (P>0.05). The level of FFA in dextran group was higher than in model group after medication,with statistical significance(P<0.01). CONCLUSIONS:Rosiglitazone can lead to weight gain by a mechanism which reduce the level of FFA.

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.

METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.

RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).

CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.

Objective To explore whether the degree of 99Tcm-methoxyisobutylisonitrile (MIBI) uptake in non-small cell lung cancer (NSCLC) could be correlated with the treatment response to three-dimensional conformal radiotherapy.Methods A total of 102 patients with NSCLC were studied with 99Tcm-MIBI SPECT before radiotherapy.The patients were classified by a follow-up CT as responders (complete or partial remission) and non-responders (stable or progressive disease).After intravenous administration of 740 MBq 99Tcm-MIBI, SPECT imaging at 10-30 min (early) and 2-3 h (delayed) were performed.Region of interest (ROI) was placed over the tumors and contralateral normal lung tissue.The uptake ratio of tumor to contralateral normal lung (T/N) was obtained from both early (ER) and delayed (DR) SPECT images.The retention index (RI) was measured as:RI = (DR - ER)/ER×100%.Statistical analysis was performed by two independent-sample t-test and Mann-Whitney U test using software SPSS 13.0.Results 99Tcm-MIBI uptake was significantly higher in responders than in non-responders:2.36 ±0.17 vs 1.82 ±0.14 (ER) and 2.48 ± 0.20 vs 1.94 ± 0.16 (DR), respectively (t = - 13.1,- 12.7, both P＜ 0.05).The median RI in the responders group was also significantly higher than that in the non-responders group (6.60% vs 5.13%, z = - 6.83, P ＜ 0.05).Conclusion ER, DR and RI of 99Tcm-MIBI SPECT might be useful to estimate the treatment response to three-dimensional conformal radiotherapy in patients with NSCLC.

To study the xanthones from the leaves of Calophyllum inophyllum Linn., several chromatography methods were employed to isolate the constituents. Investigation on the CHCl3 extract led to the isolation of a new xanthone named inophyxanthone A (1) and four known compounds, which were pancixanthone A (2), gerontoxanthone B (3), jacareubin (4) and pyranojacareubin (5). Among them, compound 2 was obtained from this plant firstly, and compound 3 was obtained for the first time from this genus. The structure of inophyxanthone A (1) was identified as 1, 3, 5-trihydroxy-2-(1, 1-dimethylallyl)xanthone by spectral analysis.

OBJECTIVETo investigate the risk factors of benazepril related cough.

METHODSCase-control study nested in a community-based postmarketing surveillance was carried out. One thousand eight hundred and thirty-one hypertensive patients screened from a Chinese community were recruited to take benazepril for 3 years. Demographic characteristics and behavior risks were investigated and the level of uric acid and creatinine were tested at baseline. Episodes of benazepril related cough during follow period were recorded.

RESULTSWithin half a year of administration, the incidence rates of cough were as high as 18.35% in women and 12.11% in men. Incidence decreased significantly when time went by. Two years later of administration, first occurrences of cough were still seen. Based on logistic regression analysis, women were more likely to develop cough (OR = 2.193, 95% CI: 1.500 - 3.206). The association between decompensated kidney function and cough occurrence was only detected in women (OR = 3.432, 95% CI: 1.954 - 6.028). Women aged 65 or more had 1.672 (95% CI: 1.040 - 2.688) times risk than women aged 35 to 64 years. In men, the OR of developing cough was 1.689 (95% CI: 0.976 - 2.924) for daily drinking alcohol less than 100 g but increased to 2.478 (95% CI: 1.148 - 5.347) when drinking 100 g or more, but not the determinant ones.

CONCLUSIONWomen, older age, drinking alcohol and decompensated kidney function were the possible risk factors for benazepril related cough, but not the determinant ones.

OBJECTIVETo investigate the long-term effect, safety and tolerability of benazepril in general hypertensive patients.

METHODSWe conducted a three-year community-based postmarketing surveillance on benazepril among 1831 essential hypertensive patients (age range from 35 to 88 years) in Shanghai.

RESULTS74.3% of patients persisted in medication taking and were with optimal compliance in a 3-year-follow-up program. Among those taking medication as prescribed after 3 years, 75.7% of them attained systolic blood pressure (SBP) target level of 140 mm Hg (1 mm Hg = 0.133 kPa), 87.4% attained diastolic blood pressure (DBP) target level of 90 mm Hg, and 71.5% attained total target level of 140/90 mm Hg. The reductions were approaching 15 mm Hg for SBP, 10 mm Hg for DBP, and 5 mm Hg for pulse pressure (PP) during the 3 year period. No serious adverse drug reactions (ADRs) were detected during the 3 years follow-up. Cough was the most common ADR. The cumulative incidence of benazepril related cough was 23.6% in women, significant higher than in men (18.8%).

CONCLUSIONBenazepril was safe and tolerable when applied in hypertensive patients.

OBJECTIVETo investigate the outcome of repairing pelvic autonomic nerve defects with the tissue-engineered nerve, in order to provide a new method and experimental evidence for solving sexual disturbance induced by pelvic autonomic nerve injury after radical resection of rectal carcinoma.

METHODSBone marrow stromal cells (BMSCs) were purified with density gradient centrifugation. A 10 mm defect of hypogastric nerve was created in 9 Beagle dogs and the 18 hypogastric nerves were randomly divided into three groups. Group A: nerve defects bridged with copolymer of lactic and glycolic acids (PLGA) tube containing BMSCs and collagen protein sponge. Group B: with PLGA tube only containing collagen protein sponge. Group C: with autologous nerve graft. The effect of nerve recovery was evaluated by morphology, HE staining, neurofilament immunohistochemistry staining, electron microscope scanning and measurement quantity of new axon 12 weeks after the transplantation.

RESULTSTwelve weeks after the transplantation, degradation of PLGA tubes showed in group A and group B. The nerves regenerated through defect area to distal end. The density of regeneration nerve fiber in group A and group C were better than that in group B. The difference was significant between group A or group C and group B (P<0.05), and no significant difference was observed between group A and group C(P>0.05).

CONCLUSIONTissue-engineered nerve, which is constructed by BMSCs mixed with collagen protein sponge and PLGA tube, can be used to bridge and repair the pelvic autonomic nerve defect.
