Objective To systematically evaluate the efficacy of traditional Chinese medicine/herbal decoction combined with ursodeoxy-cholic acid (UDCA)in the treatment of primary biliary cirrhosis (PBC),and to provide a reference for clinical medication.Methods Lit-erature published before July 31,2014 was searched in databases as follows:Cochrane Library,PubMed,China National Knowledge Infra-structure (CNKI),Chinese Scientific Journals Full-text Database (VIP),Chinese Biomedical Literature Database (CBM),and Wanfang Data.The randomized controlled trials (RCTs)comparing the efficacy of traditional Chinese medicine/herbal decoction combined with UD-CA versus UDCA alone in PBC patients were included in the analysis.The methodological quality of included trials was assessed and the data were extracted,followed by meta-analysis using RevMan 5.0 software.Results A total of 12 RCTs were included,involving 681 patients with 346 in the test group and 335 in the control group.The results of meta-analysis showed that,after 6 months of treatment,the overall response rate,improvement rate,and biochemical indices of liver function (ALT,ALP,GGT,and TBil)and hepatic fibrosis in the test group were significantly improved compared with those in the control group (all P<0.05).There were no significant differences between the two groups in the immunological indices such as IgA,IgG,anti-mitochondrial antibody (AMA),and AMA M2 subtype (all P>0.05 ). Conclusion Traditional Chinese medicine/herbal decoction combined with UDCA markedly improves the indices of hepatocellular necrosis and cholestasis,degree of hepatic fibrosis,and clinical symptoms in PBC patients after 6 months of treatment,but leads to no significant im-provement in immunological indices.Due to the limited number of included RCTs and patients through systematic evaluation,and the pres-ence of selection bias and publication bias,more double-blind randomized controlled trials with large sample size,multicenter involvement, and high quality are required to provide convincing evidence.

OBJECTIVE To give a general introduction to the infection in the hospital,and supervision to key departments in order to prevent nosocomial infection occurrence. METHODS A vertical analysis was made on the basis of the survey involving the following three periods: the first period covered the second half of the year 2000(from Jul to Dec 2000),the second period covered the second half of the year 2002(from Jul to Dec 2002),and the third period covered the second half of the year 2004(from Jul to Dec 2004). RESULTS The periodical supervision and the vertical analysis in the same period showed the following: the rates of the infected patients in the departments showing a tend to go on rising from 2000 to 2002,and showing a tend to decline from 2002 to 2004. CONCLUSIONS The control of using antibiotics must be emphasized and they should be applied in a scientific and reasonable way.The key points include the management of purchasing drugs,clinical indications and usages,supervise and news feedback,etc.All of these measures could prevent the occurrence of nosocomial infection effectively.

Small animal PET is a quantitative imaging technique that can noninvasive and dynamically image the distribution of positron-labeled radiopharmaceuticals in vivo,therefore representing a new means of providing information for drug development and evaluation.This article reviews the fundamental basis of PET imaging and their application in preclinical drug discovery and development.

Objective To evaluate the clinical value of quantitative myocardial acoustic densitometry in myocardial fibrosis in relative to the alteration in serum procollagen type Ⅲ amino-terminal propeptide(PⅢNP) concentration in hypertensive patients. Methods Seventy-five consecutive hypertensive patients were recruited with 75 normal persons served as healthy controls. The indexes of acoustic densitometry were evaluated by echocardiography and the concentrations of the serum PⅢNP peptide by radioimmunoassay. Results Calibrated acoustic intensity in septal(CAI1) and posterior wall(CAI2) in hypertension group(0.88?0.06, 0.73?0.06) were greater than that in healthy control group (0.66?0.19, 0.54?0.06) (P

Objective:To establish the HPLC fingerprints of Atractylodes lancea in northwest of Hubei province to provide the basis for the quality control and variety identification of Atractylodes lancea. Methods:The fingerprints were detected by HPLC. The separa-tion was achieved on a Diamonsil 2# C18(250 mm ×4.6 mm,5 μm)chromatographic column at 30℃ using acetonitrile-water (gradient elution) as the mobile phase at a flow rate of 1. 0 ml·min-1 . The detection wavelength was 340nm. Results: There were 13 common peaks in the HPLC fingerprints of 14 batches of Atractylodes lancea with promising separation. According to the results of clustering a-nalysis,Atractylodes lancea in northwest of Hubei province was clustered into two categories. Conclusion:A simple, feasible and relia-ble method is provided for the quality control of Atractylodes lancea.

Objective: To optimize the extraction conditions of semi-bionic extraction for Gardenia jasminoides Ellis. Methods:The best extraction conditions of the semi-bionic extraction for Gardenia jasminoides Ellis was screened by uniform design with yield of geniposide, total iridoid glycosides and dry extract as the indices. Results:The optimal conditions were as follows:the pH value of wa-ter for the lst, 2nd and 3rd decoction was 2. 0, 6. 5 and 9. 0, respectively, and the extraction time was 2. 0, 1. 0 and 1. 0h according-ly. Conclusion:The optimized extraction conditions by uniform design is scientific and reasonable.

Objective To explore the clinic results of the locking compression plate fixation for injuries at the posterior ring of pelvis. Methods 5 patients with injuries at the posterior ring of pelvis were treated with locking compression plate fixation. 2 of them resulted from crashing, 2 from crushing and 1 from falling. They included 4 males and 1 female and their average age was 35.6 years. According to AO classification system, there were 1 type B1, 2 type B2, 1 type B3 and 1 type C1; according to Dennis classification system, there were 4 section I fractures and 1 section II fracture. Results All the patients were available at follow-up, with a mean period of 5.8 months (ranging from 3 to 12 months). The average intraoperative time was 50 minutes (ranging from 30 to 80 minutes), and no patient underwent blood transfusion because the intraoperative blood loss was only 100 to 400 mL. There was no iatrogenic nerve injury and all the incisions healed during the primary procedure. The function and sense of sacroiliac joint and low extremities recovered to normal. Conclusion The locking compression plate fixation is one of the effective methods for treatment of injuries at the posterior ring of pelvis, for it is simple and minimally traumatic, and has a low rate of complications.

[Objective] To analyze application of reforming posture to anterior cervical vertebrae surgery.[Methods]The results of 50 cervical myelopathy patients,who underwent anterior cervical decompression and applied of reforming posture,were retrospectively reviewed at a mean follow-up of 2.5 years (2~4 years).[Results]Patients were also evaluated pre-operatively and post-operatively using a modified version of the Japanese Orthopedics Association Scale(JOA).78.4% of patients showed improvement rate,90% of patients showed excellent-to-good results,and the fusion rates were 100%.[Conclusion]With reforming posture,the intervertebral space of cervical vertebra was thoroughly revealed,surgical trauma was reduced,and effectiveness was improved,the time was shortened and bone fusion was enhanced.
