Objective To investigate the effects of extract of Ginkgo biloba leaves EGb761 on 1-methy-l 4-phenylpyridium (MPP+)-induced injury in human neuroblastoma SH-SY5Y cells; To discuss its mechanism of action.Methods Cell culture method was used and SH-SY5Y cell damage model was induced with different concentrations of MPP+ to build Parkinson’s disease model in vitro. The experiment was divided into control group, MPP+ model group, low-, medium-, and high-dose EGb761 groups. The survival rate was determined by MTT assay, and the apoptotic rate was detected by flow cytometry according to AnnexinV apoptosis detection kit. The cell morphology was observed by inverted microscope. NO content in SH-SY5Y cells was detected by Nitric acid reduction method.Results Compared with the control group, the survival rate of SH-SY5Y cells decreased and the apoptotic rate and NO content increased in the model group (P<0.05); Compared with the model group, the survival rate of SH-SY5Y cells increased and the apoptotic rate and NO content decreased in the low-, medium- and high-dose EGb761 groups (P<0.05).Conclusion EGb761 can protect MPP+-induced SH-SY5Y cell from damage by the inhibition of the content of NO free radical.

This study is to explore the amelioration of piperine on chronic acute combining stress rat with depression-like behavior, visceral sensitivity, and its effect on the expression of serotonin (5-HT) and synaptophysin. Forty two SD rats were divided into seven groups: blank group, model group, piperine (12.5, 25, 50 and 100 mgkg-1, ig) and imipramine (10 mgkg-1, ip) groups. The rat model of irritable bowel syndrome was established by chronic acute combining stress, and then to evaluate depression-like behavior and visceral sensitivity. The expressions of 5-HT and synaptophysin in the hippocampus and colon were determined by high performance liquid chromatography (HPLC) and Western blotting, respectively. The duration of immobility of IBS rat in the forced swimming test had been significantly increased, the sucrose consumption of IBS rat had been reduced and visceral sensitivity was obviously elevated in the IBS model group as compared with those in the normal control group (P<0.05, P<0.01). As compared with those in the normal control group, the expression of 5-HT significantly decreased, 5-HIAA/5-HT ratio significantly increased in the hippocampus of IBS model group (P<0.05), but opposite presentations were noted in the colon (P<0.05). As compared with that in the normal control group, the synaptophysin expression in the hippocampus decreased significantly but obviously increased in the colon (P<0.05). Piperine improved the behavior of IBS rats, and reversed the levels of 5-HT and 5-HIAA, and 5-HIAA/5-HT proportion in the hippocampus and colon (P<0.05); besides, they significantly reverse the synaptophysin level in the hippocampus and colon (P<0.05). The presence of depression and visceral sensitivity had been changed in IBS rats, with abnormal expression of 5-HT and synaptophysin in the brain-gut system. Piperine can ameliorate the changes of the behavior and regulation of serotonin and synaptophysin expression in IBS rat model.

Objective: To evaluate the impact of intracoronary administration of eptifibatide oncoronary no-reflow and myocardium perfusion in patients with ST-elevation myocardial infarction (STEMI) at percutaneous coronary intervention (PCI). Methods: A total of 80 STEMI patients with emergent PCI were randomly divided into 2 groups: Eptifibatide group, the patients received intracoronary administration of eptiifbatide and Control group, the patients received the same volume of normal saline.n=40 in each group. The baseline condition, post-operative vascular recanalization, changes of platelet aggression at pre- and post-medication were compared between 2 groups. Echocardiography was examined at immediately and 24 weeks after operation;myocardial infusion imaging was examined at l week after operation. All patients were followed-up for 24 weeks to observe the incidence of major adverse cardiovascular events (MACE). Results: Compared with Control group, Eptifibatide group showed increased ratios of post-operative TIMI grade 3 (72.5%vs 92.5%) and myocardium perfusion (70.0% vs 90.0%), bothP<0.05; decreased post-operative and 2h post-medicinal platelet aggression and they were both lower than Control group at the same period, allP<0.05. Eptiifbatide group had obviously improved LVEDD and LVEF at 24-week than 1-week after PCI and they were both superior to Control group, allP<0.05. There were 7 (17.5%) patients in Eptiifbatide group and 7 (7.5%) in Control group suffering from small bleeding events, P>0.05; no severe bleeding eventand no in-hospital thrombocytopeniaoccurred. MACE occurrence rates during 24-week follow-up period were 12.5% vs 22.5%, P>0.05. Conclusion: Intracoronary administration of eptiifbatide in STEMI patients at emergent PCI could effectively improve coronary blood lfow,increase myocardium perfusion and enhance cardiac function without severe bleeding events.

OBJECTIVETo compare the clinical effective differences between pricking blood combined with moxibustion and west medication for acute gouty arthritis.

METHODSForty patients with acute gouty arthritis were randomly divided into a pricking blood combined with moxibustion group (a combination group) and a western medication group, 20 cases in each one. In the combination group, pricking blood was used at the most painful points of the red turgid and painful joint once three days, total 3 times; moxibustion was applied at the same joint for 15-20 min, once a day. The moxibustion was adopted for 10 days. In the western medication group, 0. 3 g ibuprofen was prescribed orally twice a day for 10 days. The changes of uric acid (UA), high sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR) and the joint syndrome and symptom score before and after: treatment were observed. Results In the two groups, the UA, the hs-CRP, the ESR and the joint syndrome and symptom scores were lower than those before treatment (all P<0. 05). After treatment, the UA, the ESR and the joint syndrome and symptom scores in the combination group were declined more apparently than those in the western medication group (all P<0. 05). The total effective rate in the combination group was 85. 0% (17/20) which was better than 75. 0% (15/20) in the western medication group (P<0. 05).

CONCLUSIONPricking blood combined with moxibustion could improve the joint symptoms more effectively and the effect is better than ibuprofen orally.

OBJECTIVETo explore the clinical efficacy of moxibustion on rheumatoid arthritis (RA) in the patients and the impacts on the inflammatory indices.

METHODSForty RA patients were randomized into an observation group and a control group, 20 cases in each one. In the control group, diclofenac sodium sustained release tablets were used, 0.3 g each time, twice a day; methotrexate tablets were used, 10 mg each time, once a week; folic acid was used, 5 mg each time, once a week. In the observation group, on the basis of the treatment as the control group, moxibustion was added specially on the swelling and painful joints, once a day, 15-20 min each time till: the local skin turned slightly red. The treatment was given once a day, at the interval of 1 day after every 6 treatments. In the two groups, the efficacy was observed after 30-day treatment. Before and after treatment, the rheumatoid factor (RF), high sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), disease activity score-28 (DAS-28) and the score of joint symptom and physical signs were observed.

RESULTSCompared with those before treatment, the levels of RF, hs-CRP, ESR, DAS-28 and the symptom scale score were all reduced in the RA patients of the two groups after treatment (all P < 0.05). Compared with the control group, the levels of RF, hs-CRP, ESR, DAS-28 and the symptom scale score in the observation group were improved much apparently (all P < 0.05). The total effective rate was 85.0% (17/20) in the observation group and was 80.0% (16/20) in the control group. The total effective rate in the observation group was apparently better than that in the control group (P < 0.05).

CONCLUSIONMoxibustion as supplement relieves the joint symptoms, reduces the inflammatory reactive indices and improves the clinical efficacy in the RA patients.

The viral RNA was extracted from purified cymbidium mosa ic virus (CyMV) isolated from Dendrobium orchid cultivated in Hainan island. The gene of the movement protein (MP) was amplified by means of reverse transcripti on-polymerase chain reaction (RT-PCR), and cloned into pGEM-T easy vector. Se quence analysis showed that the gene fragment contained 3 open reading frames (O RFs) which may be encoding 14 kD、12 kD and 10 kD peptides. The nucleotide seque nce of the cloned gene fragment shared 97.8% homology with the MP genes of CyMV isolated from orchids cultivated in Hawaii and Singapore.

Objective To investigate the echocardiographic features and clinical significance of prenatal diagnosis of total anomalous pulmonary venous connection (TAPVC). Methods Fetal echocardiographic images of 13 fetuses with TAPVC conifrmed by pathology or postnatal echocardiography were reviewed. Echocardiographic features and clinical signiifcance of prenatal diagnosis of TAPVC were summarized. Results Twelve fetuses with TAPVC were diagnosed prenatally by fetal echocardiography, including seven cases of supracardiac type, three cases of infracardiac type and two cases of intracardiac type. The common echocardiographic characteristics of 12 fetuses with TAPVC included slightly size discrepancy of left heart and right heart, large foramen ovale with increased shunting at the atrial level, increased distance between left atrium (LA) and descending aorta, absent insertions of pulmonary veins in the LA, presence of pulmonary venous conlfuence on the top of LA and dilatation of vessels where pulmonary venous conlfuence drained. One case was missed prenatally and intracardiac type TAPVC was diagnosed by postnatal echocardiography. Among the 13 cases, three were isolated and the other ten were all in association with other abnormalities. Conclusions There are fetal echocardiographic characteristics of TAPVC. Fetal echocardiography plays an important role in prenatal diagnosis of TAPVC.
