OBJECTIVETo compare the efficacy on vertebrobasilar insufficiency (VBI) between auricular acupuncture therapy and oral administration of medicine.

METHODSSixty patients of VBI were randomized into an auricular acupuncture therapy group and a medicine group, 30 cases in each one. In the auricular acupuncture group, acupuncture was applied bilaterally to gan (CO12) and jiejie (HX8) on the ears and needles were retained for 15 min. After needle withdrawal, the vaccariae semen were fixed with plaster at naogan (AT3, 4i), zhen (AT3), jing (AH12), shen (CO10) and pi (CO13) on the ears. In the medicine group, flunarizine hydrochloride capsules (Sibelium), 5mg were prescribed for oral administration, once every night. The treatment lasted continuously for 2 weeks (14 days) in the two groups. In 2 weeks, the clinical efficacy was assessed and the transcranial doppler (TCD) examination was performed.

RESULTSAfter treatment, the symptom scores were all apparently reduced in the patients of the two groups (P < 0.01, P < 0.05). Compared with the medicine group, the reduced score was much more obvious in the auricular acupuncture group (P < 0.05), indicating the significant difference. After treatment, with TCD examination, the blood velocity was increased to different degrees in the patients of low velocity type in the auricular acupuncture group and the medicine group; that was reduced to different degrees in the patients of high velocity type in the auricular acupuncture group and the medicine group. All of them were different significantly as compared with those before treatment (all P < 0.05). But the difference was not significant between the two groups (both P > 0.05). In comparison of clinical efficacy between the two groups, the effective rate was 93.3% (28/30) in the acupuncture group and better than 76.7% (23/30) in the medicine group, indicating the significant difference in comparison (P < 0.05).

CONCLUSIONThe auricular acupuncture therapy achieves the definite efficacy on VBI and the efficacy is better than flunarizine hydrochloride capsules.

OBJECTIVETo observe the analgesic effect and safety of acupuncture-anesthetic composite anesthesia (AACA) in hysteroscopic surgery.

METHODSTotally 93 patients undergoing hysteroscopic surgery were randomly assigned to the intravenous anesthesia group (A group, 30 cases), the AACA group (B group, 32 cases), and the acupuncture combined with intravenous anesthesia group (C group, 31 cases). Patients in Group A were anesthetized by sufentanil combined propofol. Those in Group B were anesthetized by sufentanil combined acupuncture. Those in Group C were anesthetized by sufentanil, propofol combined acupuncture. Yinlian and Ququan (LR8) were needled for patients in Group B and C. The peri-operative mean arterial pressure (MAP), heart rate (HR), and oxygen saturation (SpO2), the surgical time, the recovery time, the sufentanil and propofol dosages, adverse anesthesia reactions were observed. Meanwhile, the OAA/S score, Ramsay sedation score, and Visual Analogue Score (VAS) were also measured.

RESULTSCompared with Group A and C, patients in Group B were awake, with obvious increased OAA/S score (P < 0.01). Ramsay sedation score was significantly lower (P < 0.01).The MAP and HR were elevated (P < 0.05). The patient case of SpO2 less than 85% during the operation decreased (P < 0.05). The incidence of postoperative dizziness was reduced (P < 0.05). Compared with Group A, the propofol consumption decreased in Group C (P < 0.05). There was no statistical difference in the operation time, the sufentanil dosage, VAS score, the incidence of postoperative nause- a and vomiting among the three groups (P > 0.05).

CONCLUSIONSThe patients were awake in AACA. The intraoperative sedation was better than that obtained by intravenous anesthesia. But the analgesic effect was similar to that obtained by intravenous anesthesia.

The antitussive activity assay for the root extraction of Disporum cantoniense was carried out with coughing mice induced by ammonia liquor. The results showed that the ethanol and water extractions of D. cantoniense possess strong antitussive activity, and the high dose of the former was better than positive control, and then the constituents of the ethanol extraction were separated and purified by various modern chromatographic techniques. Their structures were identified by physico-chemical properties and spectroscopic data. As a result, eight compounds were isolated and identified as stigmast-4-en-3-one(1), (22E, 24R)-ergosta-5, 7, 22-trien-3beta-ol(2), obtucarbamate A(3), obtucarbamate B(4), neotigogenin(5), azo-2, 2'-bis[Z-(2,3-dihydroxy-4-methyl-5-methoxy) phenyl ethylene] (6),dimethyl {[carbonylbis (azanediyl)] bis( 2-methyl-5, 1-phenylene) j dicarbamate (7) , and quercetin-3-O-pB-D-glucopyranoside(8). All compounds were isolated from this plant for the first time, and the result of bioactivity-directed isolation showed that compounds 3, 4, and 6 had obvious effect on antitussive activity, and compound 6 had the same level as positive control.

Objective To investigate the effect ofYindanxinnaotong (YDXNT) capsule on learning and memory abilities, super oxide dismutase (SOD) activity and malondialdehyde (MDA) content in the hippocampus of rat models of vascular dementia (VD). Methods Animals were randomly divided into sham-operated group,VD vehicle group (Group VD) and YDXNT treatment group (Group VD+YDXNT); the 4-vessel occlusion was employed to establish the VD rat models in the Group VD and Group VD+YDXNT,while rats in the sham-operated group were not performed occlusion of the bilateral common carotid artery.Rats of the Group VD+YDXNT were given 1 mL liquid (9 granules of YDXNT into 360 mL normal saline) through intragastric administration 3 times daily for a consecutive 4 weeks; and rats of the other 2 groups were given the same volume of saline.The changes of learning and memory abilities were observed by Morris water maze test; the activity of SOD and the content of MDA in the hippocampus were measured. Results As compared with those in rats of the Group VD, the learning and memory abilities in rats of the Group VD+YDXNT were significantly improved (P＜0.05):time in finding the platform was obviously decreased and swimming distance in finding the platform was obviously shortened in rats of Group VD+YDXNT.As compared with those in rats of the Group VD,the activity of SOD in the hippocampus was significantly increased and the content of MDA was obviously decreased in rats of the Group VD+YDXNT (P＜0.05). Conclusion YDXNT could increase oxygen radical metabolism to improve the learning and memory abilities of rats with VD.

Results In PBS+R group,HO-1 protein expression of EA.hy926 was low posterior to irradiation.When cells were preconditioned with Copp and/or Znpp,then recieved with 8Gy irradiation,the HO-1 protein expression of EA.hy926 increased significantly in comparision with the PBS+R group(P

To provide a scientific basis for the selection of the appropriate drying method for Mentha Haplocalyx Herba (MHH), determine 2 monoterpenes, 4 phenolic acids and 5 flavonoids in MHH by GC-MS and UPLC-TQ-MS methods, and investigate the effects of the drying methods on the changes in contents of these analytes. The qualities of products obtained with different drying methods were evaluated by the multivariate statistical method of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Results showed that the drying methods had the greatest impact on menthol, caffeic acid, and rosemary acid, which were followed by chlorogenic acid and diosmetin-7-O-glucoside. The contents in these analytes processed with hot-air-drying method were higher than those with microwave-drying and infrared-drying methods at the same temperatures. The contents in these analytes processed under low temperature (40-45 °C) were higher than those under higher temperature (60-70 °C). Above all, the contents in phenolic acids processed with microwave fixation (exposed under microwave at 100 °C for several minutes) were obviously higher than those of not being processed, showing an inhibition of some enzymes in samples after fixation. The TOPSIS evaluation showed that the variable temperature drying method of 'Hot-Air 45-60 °C' was the most suitable approach for the primary drying processing of MHH. The results could provide the scientific basis for the selection of appropriate drying method for MHH, and helpful reference for the primary drying proces of herbs containing volatile chemical components.

OBJECTIVETo make an inquiry into method of typing of hemorrhagic fever with renal syndrome (HFRS).

METHODAverage monthly rates were calculated on the basis of data from 1995 to 1999, then cluster analysis was carried out to type out endemic areas.

RESULTSCompared with the results of 36 surveillance spots from 1980 to 1992, twenty-four surveillance spots had the same results (66.7%). Twenty-three surveillance spots had the same results with the original data in 1999 (82.1%).

CONCLUSIONHFRS incidences increased in spring or in summer, but decreased in autumn or in winter. Cluster analysis seemed to be a supplementary method in distinguishing the epidemic types for HFRS.
