AIM: To explore the effects of mindfulness- based stress reduction ( MBSR ) on anxiety, compliance and visual function in primary open angle glaucoma( POAG) patients. ·METHODS:Totally 64 patients, who were treated with topical medication and were diagnosed with POAG in the department of ophthalmology at Shaanxi Provincial People's Hospital, were randomly divided into the intervention group ( n=32 ) and the control group ( n=32 ) . Both groups received conventional mental health education while the intervention group was complemented with MBSR intervention. The patient's anxiety status, compliance rates and MD before and after the intervention were evaluated. ·RESULTS:After the MBSR intervention, the scores of HAMA of the intervention group were significantly lower than that of the control group (P<0. 01). The compliance of patients in intervention group was higher than that of the control group (P<0. 01). ·CONCLUSION:The MBSR intervention can effectively relieve the anxiety of patients and improve the compliance in primary open angle glaucoma patients. It can be promoted and put into clinical application.

Objective To assess the prevalence of the metabolic syndrome (MS) in Shanghai adults according to the criteria of the US National Cholesterol Education Programme Adult Treatment PanelⅢ ( NCEP ATP Ⅲ) definition. Methods Randomly selected adults were studied by means of stratified sampling. A cross-sectional study was conducted in Shanghai with a representative sample of 7 414 Chinese adults aged 35-74 years.Results Defined by the ATPⅢ criterion, the preliminary prevalence of MS was 19.81%. The prevalence of MS was 16.21% (95%CI 15.37%-17.05% ) after age was adjusted. The prevalence of MS was higher in female than in male (22.59% vs 16.64% ,P<0.01 ), and higher in urban than rural residents( 17.43% vs 17.16% ,P<0.01 ). The prevalence of MS increased with age in both male and female, especially in females aged above 55 years. There were 19.81% subjects with over 3 risk factors. The most common combination of four components in MS were central obesity, high triglyceridemia, low high-density lipoprotein-cholesterol and hypertension. Conclusions There is a high prevalence of MS in Shanghai adults. MS is increasingly becoming a noteworthy health problem. Early-diagnosis and integrated-methods of prevention and treatment of MS are mandatory.

Objective To observe the therapeutical effect of posterior vertebral column resection on chronic thoracolumbar tuberculosis with secondary paraplegia and to provide a safe and effective method for the treatment of chronic thoracolumbar tuberculosis with secondary paraplegia.MethodsFrom Aug.2007 to Mar.2010,12 cases with chronic thoracolumbar tuberculosis and secondary paraplegia were surgically treated by posterior vertebral column resection and Titanium net support for bone graft and internal fixation operation treatment.Cobb angle was measured,and conditions of internal fixation were observed before and after the operation by X-ray films.Neurological status were evaluated by Frankel grades.ResultsThe follow-up periods was 6- 18 months( on average 11 months).Operations eased all patients' back and chest pain.Frankel grade increased from C preoperatively to grade D or E postoperatively in 6 cases,from grade D to E in 4 cases and from grade B to C in 1 case.No obvious improvement of Frankel grade was observed in the other patient of grade B.The average Cobb angles were(76.0 ± 23.4) ° before surgery,( 15.5 ± 6.3 ) ° at one week after surgery and ( 16.0 ± 8.2) °at the last follow-up.The difference in the Cobb angle before and at one week after treatment was significant( t =3.41,P ＜ 0.01 ).No difference was found in the Cobb angle between at one week after treatment and at the last follow-up (t =1.58,P ＞ 0.05 ).All patients got bony fusion with Titanium net.No complications occurred with internal fixation.Conclusion Posterior vertebral column resection is a feasible method for the treatment of chronic thoracolumbar tuberculosis with secondary paraplegia.It achieves neurological decompression with high correction rate and minor injury,and no anterior surgery is needed.

Objective:To investigate the effects of sinomenine(SIN)on the activation and function of T-cells from SLE patients and to elucidate the mechanisms for the immunosuppressive effect of SIN.Methods:PBMCs were isolated from SLE patients and stimulated with anti-CD3 in the presence or absence of different concentrations of SIN.The cytokines were measured by ELISIA,and the activation and function of T-cells were analyzed by flow cytometry.Results:SIN could inhibit IFN-?,IL-2 and IL-4 production of T cells in SLE patients' peripheral blood.In addition,SIN could significantly inhibit the expression of activation molecules CD69 and CD25 by CD4+ and CD8+ T cells.Conclusion:SIN could inhibit immune responses of SLE patients by suppressing T cells activation and cytokine secretion.

OBJECTIVE:To systematically evaluate the effectiveness of probiotics in adjunctive prevention and treatment of chemotherapy-induced diarrhea(CID),and to provide evidence-based reference in the clinic. METHODS:All relevant randomized controlled trials (RCTs) of probiotics in adjunctive prevention and treatment of CID were collected by searching EMBase,Co-chrane library,PubMed,CJFD,VIP,Wanfang databases and CBM. Meta-analysis were performed with Rev Man 5.2 software af-ter data extraction and quality evaluation by Cochrane Hand book 5.0risk-bias assessment tool. RESULTS:10 RCTs were includ-ed,involving 871 patients. The results of Meta-analysis showed that addition of probiotics on the basis of conventional symptomatic therapy significantly reduced the total rate of diarrhea in cancer patients [OR=0.31,95%CI(0.20,0.49),P<0.001] and Ⅲ-Ⅳ diar-rhea rate[OR=0.09,95%CI(0.03,0.24),P<0.001],improved overall response rate [OR=4.16,95%CI(2.40,7.23),P<0.001] and complete remission rate [OR=2.55,95%CI(1.66,3.90),P<0.001],with statistical significance. The probiotics had little effect onⅠ-Ⅱlevel diarrhea rate[OR=0.86,95%CI(0.48,1.56),P=0.62] and partial remission rate[OR=1.00,95%CI(0.67,1.50),P=1.00],with statistical significance. CONCLUSIONS:The use of probiotics before chemotherapy can effectively prevent the occur-rence of severe CID in cancer patients;in the treatment of CID,the combination of probiotics can also improve therapeutic effica-cy of conventional symptomatic treatment.

Objective To construct a recombinant lentiviral expression vector containing NIS and EGFP gene,and to explore the feasibility of NIS gene for monitoring the bone marrow derived mesenchymal stem cells (BMSCs) migration to the intracranial glioma.Methods The NIS and EGFP gene fragments were subcloned into lentiviral vector pLVX-puro,then packaged and amplified in HEK293T cells to obtain recombinant lentivirus pLVX-CMV-NIS-EGFP.pLVX-CMV-0-EGFP was constructed as control.BMSCs were isolated,cultured,and transfected by lentivirus.The antibiotic-resistant transfected BMSCs (BMSCs-NIS-EGFP and BMSCs-EGFP) were selected.The expression of NIS gene was examined by Western blot.Functional NIS activity was confirmed by the uptake of 125I and the inhibition effect of NaClO4.The nude mice intracranial glioma models were established.MicroSPECT was performed at 24 h post BMSCs-NIS-EGFP injection via the tail vein.Results pLVX-CMV-NIS-EGFP and pLVX-CMV-0-EGFP were successfully constructed and packaged.BMSCs were successfully isolated and cultured.Stable cell lines BMSCs-NIS-EGFP and BMSCs-EGFP were constructed after lentivirus transfection and puromycin selection.The expression of NIS gene was detected by Western blot in BMSCs-NIS-EGFP,but not in BMSCs-EGFP.BMSCs-NIS-EGFP showed significantly more uptake of 125I (nearly 10 times than the uptake in BMSCs-EGFP) and the uptake could be significantly inhibited by NaClO4.The nude mice intracranial glioma models were successfully established and the BMSCs-NIS-EGFP in glioma foci could be visualized by microSPECT imaging at 24 h post injection.Conclusions A recombinant lentivirus containing NIS gene could be successfully constructed for monitoring BMSCs migration towards intracranial glioma.It might provide evidence on the research of BMSCs and NIS gene mediated therapy for glioma.

Ultra high performance liquid chromatography coupled with a Q Exactive hybrid quadrupole-orbitrap mass spectrometry ( UPLC-MS/MS) and multivariate statistical analysis was applied to metabonomic
study of drug-induced liver injury. This investigation focused on the liver injury in clinic which was induced by antitumor drug, traditional Chinese medicine, statins and antibiotics. After precipitated by cold acetonitrile, the serum samples were separated on a HSS T3-C18 column using water (containning 0. 01% formic acid) and acetonitrile as mobile phase by gradient elution. Based on metabonomic profiles analysis of the orthogonal projections to latent structures discriminant analysis ( OPLS-DA ) and partial least squares-discriminant analysis ( PLS-DA) , 114 endogenous metabolites had been found to have significant differences between drug-induced liver injury patients and healthy volunteers, 38 endogenous metabolites have significant difference (p<0. 001). According to the results of the OPLS-DA, MS/MS data and human metabolome database ( HMDB) , phenylalanine and dimethylguanosine had been identified as potential biomarkers related to drug-induced liver injury for early discovery and diagnosis.

Objective To compare the effect between problem-based learning and lecture-based learning for clinical teaching in the department of cardiovascular medicine. Methods Totally 110 five-year-program cardiovascular interns from June 2011 and June 2012 were selected. They were randomly divided into the PBL group(n=55) and LBL group(n=55). PBL and LBL teach-ing methods were applied in the two groups respectively. Teaching effects were evaluated by exam and questionnaire investigation. SPSS 15.0 was used to do data processing; t test was used to compare the average score of two groups;chi-square test was used to process the results of the questionnaire. P<0.05 signifies sta-tistically significant differences. Results There were statistical differences in examinational average score between PBL group and LBL group ((87.89 ±5.39) vs. (82.63 ±5.26), P<0.05). PBL group had significantly higher satisfaction rate in motivating study interests , deepening understanding of theoretical knowledge, cultivating self-learning ability, training verbal expression and developing clin-ical thinking, etc(P<0.05). Conclusions PBL teaching method demonstrates advantages in teaching of cardiovascular medicine and enhances the teaching effect. But the PBL teaching method should be improved in basic knowledge teaching, cultivation of teachers' ability and case selection.
