Objective To assess the effectiveness of repeated trans-cranial magnetic stimulation ( rTMS) in relieving post-stroke depression ( PSD). Methods PubMed, Embase, the Cochrane library, Web of Science, CNKI, WANFANG, and VIP were searched for reports of randomized, controlled trials of rTMS treatment of PSD published before June 2015. Crude standardized mean differences ( SMDs) and odds ratios with 95% confidence in-tervals ( CIs) were calculated for depression intensity and effectiveness rate after treatment using random or fixed effects models. Results Twenty-four studies involving 856 rTMS-treated patients and 802 control patients were in-cluded in the meta-analysis. The results showed that compared with the control group, PSD patients showed significant reductions in depression after rTMS treatment ( SMD=-1.36;95% CI-1.6 to-1.12;P≤0.05) . The total effective-ness rate in the treated group was 85% with a reduction in NIHSS score ( SMD=-0.82;95% CI-1.2 to-0.44;P≤0.05) . Subgroup analysis showed that neither the frequency of rTMS stimulation, the site stimulated, nor time after stroke had a significant influence on the effectiveness of rTMS. Additionally, a few studies reported adverse reactions after rTMS. Conclusion rTMS appears to be a safe and effective therapy for PSD. Further well-controlled trials may elucidate the mechanism underlying the placebo effects of the sham rTMS observed among PSD patients.

[Abstract] Objective To evaluate the effect of Mycobacterium tuberculosis Direct Assay (MTD) for rapid detecting Mycobacterium tuberculosis rRNA and Multi-locus PCR for M.bovis BCG strain typing in patients with suspected extra-pulmonary tuberculosis.Methods From June 2010 to December 2011,47 children and 75 adult patients with suspected extra-pulmonary tuberculosis in Shanghai public health clinical center were recruited.Also 48 non-tuberculosis patients were taken as a negative control.Clinical specimens from these patients were collected.Acid fast stain,solid culture,liquid culture,and MTD were used to detect all clinical specimens simultaneously.Screen tuberculosis strains of the culture isolates by MPT64 antigen assay and use Multi-locus PCR for the BCG strain genotyping of the isolates without MPT64 antigen.SPSS16.0 was used to analyse the results.Results The sensitivity for acid fast stain,solid culture,liquid culture and MTD test was 10.7％ (13/122),11.5％ (14/122),16.4％ (20/122) and 37.7％ (46/122),respectively.And the specificity of MTD was 100.0％.Six clinical isolates from children were identified as BCG by Multi-locus PCR typing,the same with chemical tests.Conclusions The MTD assay and the MGIT960 liquid culture are effective and reliable method for diagnosing extra-pulmonary tuberculosis.And Multi-locus PCR can be assisted for the early diagnosis of extra-pulmonary tuberculosis patients with suspected BCG infection.

Objective To establish a method for determining oxalate and citrate in urine simultaneously by capillary electrophoresis.The components,the concentration and pH of the buffer solution,the separation voltage and the injection time on theseparation were studied in detail.Methods The separations were carried out using potassium dihydrogen phosphatebuffer ina fused-silica capillary tubeby capillary zone electrophoresis (CZE) and the detection were monitored by UV.24 h-urine samples from patients (n =5) and health control (n =5) were collected from Zhongshan Hospital of Fudan University for systematically validating the method developed.Results The optimized separations were carried out using a 50 mmol/L potassium dihydrogen phosphatebuffer solution (pH 6.5) in a fused-silica capillary tube of 50 cm × 50 μm I.D.Injections were made by using the pressure mode for 10 s at 34 mbar.The detections were monitored by a UV at 200 nm after samples were separated at avohage of 30 kV.Under the seconditions,urinary oxalate and citrate were separated completely within 5 min.The relative standard deviations of migration time and peak area within-run foroxalate and citrate were less than 1％ and 3.0％ and the betweenrun relative standard deviations were less than 2.0％ and 4.0％,respectively.The detection limits were 1 mg/L for both oxalate and citrate.The linearity ranges of oxalate and citrate were both 0-500 mg/L with the correlation coefficient between 0.999 5 and 0.995 4 (P ＜ 0.05),respectively.The average recoveries were 102.38％ for oxalate and 92.74％ for citrate.Conclusion This method is proved to be simple,sensitive and accurate,and also applied to determine oxalate and citrate in urine samples with satisfactory results.

Literatures on acupuncture-moxibustion treatment of chemotherapy-induced peripheral neuropathy (CIPN) in the recent decade were searched in the databases of Pubmed, MEDLINE, Biological Abstracts, EMBASE, Sinomed, CNKI, Wanfang, VIP, et al. The general situation was comprehensively analyzed and reviewed from experimental design, treatment method, efficacy evaluation, mechanism research and so on. The results showed that acupuncture has a certain therapeutic effect, but the research is still in the preliminary stage, the relative literatures are insufficient and in a low quality. There is still a controversy on the efficacy of acupuncture in the treatment of CIPN. High quality, large sample and multicenter randomized controlled trials and systematic reviews are needed to verify the efficacy of acupuncture. The mechanism of acupuncture treatment of CIPN is still unclear and needs further research and exploration.

The current clinical efficacy evaluation system and evaluation methods of acupuncture have several limitations, and the application status is not optimistic. According to long-term observation, minimum clinically important difference (MCID) is consistent with the characteristics of clinical acupuncture, and has objective quanti- tative standard and wide applicability. Incorporating MCID into acupuncture clinical efficacy evaluation of tradition- al Chinese medicine can truly reflect the clinical effect of acupuncture and improve the disadvantages and shortcom- ings of acupuncture clinical evaluation, which could provide certain reference for building clinical efficacy evaluation system featured with TCM.

Objective To investigate the effect of curcumin on Aβ production in swAPP HEK293 cells and its preliminary mechanism.Methods swAPP HEK293 was used as cell model,the effect of curcumin (at different time points and of concentration) on cell viability was accessed by MTT assay.After the cells were treated with non-cytotoxic concentration of 5 μmol/L for different time,ELISA was used to detect Aβ production.The concentration and the time point of the strongest inhibitory effect were selected for the following tests.Real time PCR was employed to analyze miR-153 and APP mRNA expression,and Western blot was used to detect APP protein expression.Results As compared with the control group,curcumin of ≤ 5 μmol/L had no toxicity effect on the cell viability (P ＞ 0.05).Curcumin significantly inhibited Aβ production (P ＜ 0.05).Therefore 5 μmol/L curcumin and 24 h were selected as the best concentration and timc.Curcumin of 5 μmol/L had no obvious impact on APP mRNA expression (P ＜ 0.05),whereas markedly decreased APP protein expression.In addition,miR-153 level in the cells was significantly increased by 5 μmol/L curcumin treatment (P ＜ 0.05).Conclusion Curcumin may inhibit Aβ production through up-rcgulating miR-153 level and reducing APP protein expression in swAPP HEK293 cells.

Background and purpose: Uridine diphosphoglucu-ronosyl transferase 1A1 (UGT1A1) is an important enzyme for metabolism of irinotecan. The activity of UGT1A1 enzyme was significantly affected by the gene polymorphism. This study aimed to investigate the correlation of UGT1A1*28 and *6 gene polymorphisms with irinotecan-based chemotherapy in colorectal cancer(CRC). Methods: Analysis of UGT1A1*28 and *6 gene polymorphisms was performed in 160 gastrointestinal cancer patients admitted to Zhongshan Hospital Fudan University from Apr. 2013 to Dec. 2013 by amplifying the gene fragments using PCR, STR and Sanger sequencing. Eighty-two cases with CRC treated with irinotecan were chosen to observe the adverse events during chemotherapy. The incidence of different genotypes was compared. Results:The distribution of the genotypes in 160 gastrointestinal cancer patients was as followed:UGT1A1*28 wild-type genotype TA6/6 (124, 77.5%), heterozygous genotype TA6/7 (33, 20.5%), and homozygous genotype TA7/7 (3, 2.0%);UGT1A1*6 wild-type genotype GG (105, 65.6%), heterozygous genotype GA (48, 30.0%), and homozygous genotype AA (7, 4.4%). In the 82 CRC cases, the incidences of grade 3 and 4 neutropenia in the patients carrying UGT1A1*28 (TA6/7+TA7/7 ) were higher than those in the WT genotype (TA6/6) (58.3%vs 0.0, P<0.001), and increased the total incidence of adverse events (76.0%vs 45.6%, P<0.001). There was no signiifcant relevance between UGT1A1*6 genotype, age, gender chemotherapy and adverse events. Conclusion:In the CRC cases with irinotecan-based chemotherapy, the UGT1A1*28 (TA6/7+TA7/7) genotype signiifcantly increased the risk of grade 3 and 4 neutropenia. Detecting UGT1A1 gene polymorphisms may guide individualized treatment and predict adverse events.

Objective To investigate the correlation between the mutation of pncA gene and the susceptibility to pyrazinamide ( PZA) in Mycobacterium tuberculosis complex ( MTBC) strains and to analyze the mutation of panD and rpsA genes in wild type isolates without pncA gene mutation.Methods The sus-ceptibilities of 108 MTBC strains to first-line drugs including PZA were detected by using the MGIT 960 TB system.PCR was performed to amplify the 16S rDNA and pncA, panD and rpsA genes.The PCR products were analyzed by DNA sequencing analysis .Results Among the 78 multidrug-resistant MTBC strains , 47 isolates (60%) were resistant to PZA.Four out of 30 (13%) strains that were sensitive to ethambutol , iso-niazid, rifampicin and streptomycin (EIRS) were resistant to PZA.The drug-resistant MTBC strains showed higher resistance rate to PZA than that of the EIRS sensitive strains .There were 49 ( 96%) PZA-resistant isolates and 4 (7%) PZA-sensitive isolates occurred pncA gene mutation.Most of the pncA gene mutations in the genomes of PZA-resistant strains were base substitution mutation , especially the His57Asp substitu-tion.The pncA gene mutations centralized in the regions of 160-169, 203-289, 309-396 and 413-467.Seven novel mutation sites of pncA gene were observed including T175C, C188A, G insertion at 68, AGC insertion at 235, C insertion at 339, CC insertion at 392 and GT deletion at 395.The mutation sites founded in the genomes of PZA-sensitive strains were different from those of the PZA-resistant strains .No mutation of the pncA gene and the upstream regulatory sequence was found in two PZA-resistant strains , NJ44 and NJ108 . The sequence analysis of panD and rpsA gene showed that the NJ 108 strain had panD gene mutation at G419A, but no mutation was detected in the NJ 44 strain.Conclusion The multidrug-resistant MTBC strains showed higher resistance rate to PZA .The pncA gene mutation was common in PZA-resistant MTB strains and the panD gene mutation was also worthy of attention .

ObjectiveTo analyze the characterstics of phenotype and genotype of multidrug resistant tuberculosis (MDR-TB) and extensively drug resistant tuberculosis (XDR-TB) by molecular line probe assay and liquid culture with MGIT960.MethodsGenoType MTBDR Kits were used for identifying the types of the first-line and second-line antituberculosis drug resistant genes partly and BD MGIT960 was used for detecting the chug susceptibility.Results( 1 ) Out of 94 MDR-TB strains,the rate of drug resistant to EMB,AMK,OFX and MFX by BD MGIT960 assay were 36.2%,17.0%,54.3% and 55.3%,respectively.Among these isolates,13 were extensively drug resistant tuberculosis (XDR-TB).(2) Compared with MGIT960,the concordance rate of GenoType MTBDRplus was 86.2% and 95.7% respectively.Taking MGIT960 results as reference,the sensitivity of GenoType MTBDRsl detecting the susceptibility of EMB,AMK,OFX and MFX to 94 isolates were 47.1%,81.3%,94.1%,94.2%,respectively.The specificity were 75.0%,98.7%,90.7%,92.9%,respectively.(3) Among the rpoB mutation categories,S531L accounts for most.MTB resistant to IFN caused by the mutation of katG chiefly and the S315T1 was in the majority.The gyrA mutation sites located at the ninety-fourth codon most.Out of 94 strains,23 were mixed with 2 kindsof Mycobacterium tuberculosis at least and 7 were undetectable mutations.Conclusion Among the M/XDR-TB,the strains resistant to INH,RFP,AMK,OFX and MFX were caused most by the mutation of katG,rpoB,rrs and gyrA,respectively.The relationship between EMB and embB was not so clear relatively.As a fast detecting drug susceptibility test kit,GenoType MTBDR possess good sensitivity and specificity.So,it could be as an assistant method to guide the therapy on clinic.
