OBJECTIVETo observe the efficacy difference of electroacupuncture and auricular acupuncture in the treatment of methamphetamine withdrawal syndrome.

METHODSNinety male patients of methamphetamine addiction were randomized into an electroacupuncture group, an auricular acupuncture group and a control group, 30 cases in each one. In the electroacupuncture group, Neiguan (PC 6), Shenmen (HT 7), Zusanli (ST 36), Sanyinjiao (SP 6), Jiaji (EX-B 2) at T5 and L2 were selected bilaterally. In the auricular acupuncture group, jiaogan (AH(6a)), shenmen (TF4), fei (CO14) and gan (CO12) were selected unilaterally. The treatment was given 3 times a week, totally 12 treatments were required. In the control group, no any intervention was applied. Separately, before treatment and after 1, 2, 3 and 4 weeks treatment, the scores of methamphetamine withdrawal syndrome, Hamilton anxiety scale and Hamilton depression scale were observed in each group.

RESULTSThe total score of methamphetamine withdrawal syndrome, anxiety score and depression score were obviously reduced in 2, 3 and 4 weeks of treatment as compared with those before treatment in the electroacupuncture group and the auricular acupuncture group (all P < 0.05), and showed a trend of gradual decline as the extension of treatment. In 1,2,3,4 weeks of treatment, the total score of withdrawal syndrome, anxiety score and depression score in the electroacupuncture group and auricular acupuncture group were lower significantly than those in the control group (all P < 0.05), in which, the total score of withdrawal syndrome in the electroacupuncture group was lower significantly than that in the auricular acupuncture group in the 4th week of treatment (3.69 +/- 2.446 vs 5.73 +/- 3.169, P < 0.05); the anxiety scores were lower significantly than those in the auricular acupuncture group in 3 and 4 weeks of treatment (8.19 +/- 4.57 vs 9.65 +/- 4.24, 5.27 +/- 2.89 vs 7.38 +/- 3.10, both P < 0.05); the depression scores were lower significantly than those in the auricular acupuncture group in 2, 3 and 4 weeks of treatment (15.35 +/- 5.64 vs 19.81 +/- 5.37, 10.96 +/- 4.52 vs 15.00 +/- 4.53, 7.96 +/- 2.69 vs 12.35 +/- 3.59, all P < 0.05).

CONCLUSIONElectroacupuncture at the body points and auricular acupuncture play the therapeutic role in the treatment of methamphetamine withdrawal syndrome, anxiety and depression. The longer time the treatment is with electroacupuncture at the body points, the more obvious the efficacy will be on the above symptoms.

The chemical consitituents from cytotoxic fraction of the Callicarpa nudiflora extract were isolated and purified by a combination of HP-20 macroporous resin, silica gel and Sephadex LH-20 column chromatographies. The structures were elucidated on the basis of the spectroscopic data and comparison of their spectroscopic data with reported data. The cytotoxicity was evaluated by the MTT assay. The 50% and 70% EtOH elutions of EtOH-extract showed significant cytotoxic activities, leading to the isolation of twelve compounds, which were identified as luteoloside(1), lutedin-4'-O-β-D-glucoside(2), 6-hydroxyluteolin-7-O-β-glucoside(3), lutedin-7-O-neohesperidoside(4), rhoifolin (5), luteolin-7, 4'-di-O-glucoside (6), forsythoside B (7), acteoside (8), alyssonoside (9), catalpol(10), nudifloside(11), and leonuride(12). Compounds 3-6, 10 and 12 were isolated from this genus for the first time, and compound 9 was isolated from this plant for the first time. The cytotoxicity assay demonstrated that flavonoids 1-6, in various concentrations, showed monolithic proliferation inhibitory activities against Hela, A549 and MCF-7 cell lines. Compounds 3, 5 and iridoid glycoside 11 possessed higher cytotoxicacivities. In short, flavonoids are the main components of cytotoxic extract from C. nudiflora, while phenylethanoid glycosides are the predominant ingredient but inactive to cancer cell lines. In addition, the minor iridoid glycoside expressed weak cytotoxic activity.

Objective To analyze the clinical features of pandrug-resistant Acinetobacter baumannii (PDR-Ab) in a hospital and compare the efficacy of different antibiotic treatments on patients with pneumonia caused by PDR-Ab.Methods Data were ret- rospectively collected from all isolated PDR-Ab strains in our hospital from February 2004 to March 2005.The clinical features and outcomes were reviewed.Results A total of 77 strains of PDR-Ab were collected, 45 of which were pathogens causing clini- cal infections (35 strains from lower respiratory tract, 6 from bloodstream, 3 from drainage fluid, and 1 from wounds).Lower respiratory tract was the most common source of PDR-Ab.More than 90% of the isolated PDR-Ab strains produced OXA-23 type?-lactamase.Cefoperazone-sulbactam plus minocyeline showed good efficacy for patients with PDR-Ab pneumonia.The total clinical cure rate was 68.4%.Bacterial eradication rate was 42.1%.The factors influencing bacterial clearance were pro- longed mechanical ventilation prior to positive culture (17.5 d vs 5.5 d).mixed infection (100% vs 12.5%) and lower GCS score (9.1?0.7 vs 13.2?2.1).Concomitant septic shock (OR=13.8) and APACHEⅡscore (OR=2.1) were independent factors of clinical outcome.Conclusions Nosocomial infections caused by PDR-Ab are not untreatable.Our analysis suggests that cefoperazone-sulbactam plus minocycline may be an effective treatment for lower respiratory tract infections caused by PDR-Ab in our hospital.

Objective To investigate the relationship between high-sensitivity C-reactive protein(hsCRP), pulse pressure(PP) and microalbuminuria(MAU) in patients with essential hypertension.Methods Consecutive 60 patients with essential hypertension were classified based on the MAU level:patients with MAU(n=30) and the group of patients with normoalbuminuria(NMAU,n=30) with 30 healthy subjects as control.MAU,hsCRP,PP were determined.Results The level of hsCRP and pulse pressure in MAU group were higher than those in NMAU patients and healthy subjects (P

OBJECTIVETo objectively evaluate the clinical effect of acupoint injection therapy for chronic gastritis of gastric blood stasis type.

METHODSOne hundred and two cases arranged by registration order were randomly divided into an acupoint injection group and a medicine group, 51 cases in each group. The acupoint injection group was treated with acupoint injection of compound Danshen injection, and Zusanli (ST 36) and Weishu (BL 21) were selected, and the medicine group with oral administration of Omeprazole. After 2 weeks of treatment, the clinical effect and improvement of endoscopic gastric mucosal lesions were observed.

RESULTSThe clinical total effective rate of 96.1% (49/51) in the acupoint injection group was better than 76.5% (39/51) in the medicine group (P < 0.01). The symptom score decreased significantly after treatment and the gastric mucosal lesion was significantly improved in both of the two groups (all P < 0.05), and the acupoint injection group was superior to the medicine group (all P < 0.05).

CONCLUSIONAcupoint injection has outstanding effect for treatment of chronic gastritis of gastric blood stasis type and this therapy is worth generalizing and applying.
