AIM:To observe the effects of the combination of berberin and epirubicin on the cell cycle of T24 bladder cancer cells and the underlying mechanisms.METHODS:The cancer cells were exposed to epirubicin in the presence or absence of different concentrations of berberin.The viability of the cancer cells was determined by MTT assay.The cell cycle distribution was detected by flow cytometry, and the protein levels of cyclin D1, CDK2, CDK4, P21 and P27 were detected by Western blot.RESULTS:Berberine markedly enhanced the inhibitory effect of epirubicin on the viability of T24 cells and promoted epirubicin-induced cell cycle arrest at G0/G1 phase as compared with the negative control cells.Epirubicin increased the protein expression of P27 and P21, both of which were enhanced by treatment with berberin.In contrast, berberin exposure further decreased the protein expression of cyclin D1, CDK2 and CDK4 in epirubicin-treated T24 cells.CONCLUSION:Berberine significantly promotes epirubicin-induced G0 /G1 phase arrest in human bladder cancer cells by up-regulating P27 and P21 expression and inhibiting the expression of cyclin D1, CDK2 and CDK4.

Objective To evaluate the validity and reliability of the Chinese version of Alcohol Withdrawal Scale (AWS). Methods Totally 175 patients diagnosed as alcohol dependence according to the criteria of ICD-10 were studied. Intraclass correlation coefficient (ICC) analysis was applied for examining interrater consistency and Cronbach' s α for internal consistency. Factor analysis was used to examine the construct validity. Correlation analysis between AWS and CGI,Revised Clinic Institute Alcohol Withdrawal Syndrome Scale(CIWA-Ar) were conducted to evaluate the criterion validity. Based on clinical criteria,ROC curve was calculated so as to test the discriminative ability and establish the cut-off point of the scale. Results ( 1 ) Reliability: ICC value was 0.93,and Cronbach's α was 0.83,which indicated good interrater and internal consistency. (2) Validity:the correlation coefficients of the two subscale with the total scale score were 0.78,0.83 respectively. The correlation coefficients between the subscale were 0. 81 and factor analysis revealed that each item of the scale had relatively high load on the primary factor (0.409 ～0.926). At the time of admission,the total score of the AWS was positively correlated with that of CGI ( r = 0.71, P < 0.05 ). The total score of the AWS also was positively correlated with that of CIWA-Ar ( r = 0. 86, P<0. 05). As treatment went on,total score of the AWS showed a downward trend,at the end of the first week,the total score of the AWS was positively correlated with that of CGI ( r = 0.62, P<0.05). (3)The cut-off point of AWS for mild alcohol withdrawal state was determined as ≥3. With this cut-off point,AWS had both high sensitivity (92.1% ) and specificity (73.5% ) ,and the area under curve (AUC) was 0. 91. The cut-off point of AWS for moderate withdrawal state was determined as ≥7, and the sensitivity and specificity of AWS were 94.3 % and 89.7 % respectively, with the AUC of 0.94. The cut-off point of AWS for severe withdrawal state was determined as ≥ 10. With this cut-off point AWS had both high sensitivity (94. 9% ) and high specificity (92.6% ) .with the AUC of 0.93. Conclusion AWS has good reliability and validity and can reflect the change of the disease and the efficacy of treatment.

OBJECTIVETo investigate the relationship between the resistance index (RI) of the renal artery and serum creatinine (Cr) level in patients early (within one month) after renal transplantation.

METHODSA total of 123 patients receiving renal transplantation underwent examinations by color Doppler ultrasound for measurement of the RI of the renal artery within one month after the operation. According to the results of RI measurement, the patients were divided into RI≥0.75 and RI<0.75 groups for analyzing the correlation between RI and serum Cr level measured at the same time points.

RESULTSThe RI and Cr levels in patients with RI≥0.75 showed a significant positive correlation (P<0.05), whereas they showed an inverse correlation in patients with RI<0.75 (P<0.05). The patients with RI≥0.75 had significantly lower RI of the renal artery and Cr level than those with RI≥0.75.

CONCLUSIONRI is significantly correlated to Cr, and may serve as an indicator for predicting renal graft function after transplantation.

Objective To study the characteristics of work disability and its influencing factors in patients with ankylosing spondylitis (AS). Methods The demographic data, work conditons and disease related characteristics of 277 patients with AS were recorded, and randomly selected from the Department of Rheumatology, Chinese PLA General Hospital from November 2014 to January 2016. Work and productivity activity impair-ment questionnaire (WPAI) was used to survey the work disability and productivity loss, then explore its in-fluencing factors and the relationships between patient-reported outcomes and WPAI scores. Logistic regression was used to analyze the associated factors of work disability. Multivariate linear regression was used to analyze the predictive factors of lose of work productivity. Results The prevalence of work disability was 30.3%. Twenty patients were unemployed because of working disability. Two hudreds patients were employed, with average 36.5 (24.0, 50.0) hours workingtime in the past week. Average AS related absenteeism was 4.4 (0, 10) hour. Average workproductivity loss was 26.4%(2.5%, 40.0%). Logistic multiple regression analysis showed that Bath AS disease activity index (BASDAI), SF-36 physical component summary (PCS) scores might be the important influencing factors among those clinical measures ( OR=1.270, 0.959). Presenteeism and overall work impairment were moderately correlated with patients' global assessment of disease activity (VAS), BASDAI, bath AS functional index (BASFI), SF-36 physical Functioning (PF), SF-36 body pain (BP) and SF-36 Physical Component Summary (PCS) (|r|=0.539-0.648). Linear multivariate analyses indicated that work presente-eismand absenteeismwere significantly associated with BASDAI (P<0.01). Conclusion High prevalence of work disability in patients with AS is noted, which is closely related with disease activity and body function;High attention should be paid to AS patients with work disability.

OBJECTIVETo study the effects of modified Huopo Xialing Decoction (HXD) in treating patients of Pi-Wei dampness-heat syndrome (PWDHS) and its impact on epithelial cell apoptosis of tongue.

METHODSFifty patients with PWDHD were randomized depending on their visiting sequence into two groups, the 30 patients in the treatment group treated with HXD and the 20 in the control group treated with Domperidone. The therapeutic course for both groups was 2 weeks. Besides, a normal control group consisting of 30 healthy volunteers was set up. The changes of tongue fur, grade of major syndromes in different groups were observed and scored before and after treatment to evaluate the therapeutic effectiveness, and the apoptotic index (AI) was estimated using TUNEL technique.

RESULTSAI in the two patient groups before treatment was obviously lower than that in the normal group (P < 0.01 or P < 0.05); after treatment, AI in the treatment group increased significantly (P < 0.01), with no difference from that in the normal group (P > 0.05), while in the control group, it only showed a slight trend of increasing. Similar outcome of tongue fur grades was seen in the two groups, it was improved significantly (P < 0.01) in the treatment group but insignificantly in the control group (P > 0.05). After treatment, syndrome scores were both lower in the two groups (P < 0.01), but the decrement in the treatment group was more significant than that in the control group (P < 0.01). Comparison between groups showed that the total effective rate in the treatment group was significantly superior to that in the control group (90% vs 65%, P < 0.01).

CONCLUSIONHXD has good clinical efficacy in treating PWDHS, and has good effect in alleviating the greasy yellow tongue fur in patients with PWDHS by accelerating the tongue epithelial cell apoptosis.

AIMTo study the protective effects of ramipril in combination with BQ-123 on myocardial ischemia/reperfusion (I/R) injury in vivo in anesthetized rats.

METHODSHealthy male Wistar rats were divided into 5 groups randomly and subjected to 30 min of myocardial ischemia followed by 120 min reperfusion. Ramipril, BQ-123 and their combination were given to rats respectively. To observe the protection of their combination against myocardial I/R injury. HR, MAP and the change of ST-segment were observed. Ventricular arrthymias were monitored. The activity of creatine kinase (CK) and lactate dehydrogenase (LDH) in plasma, the infarct size and morphologic change were examined.

RESULTSCompared with I/R group, the elevation of ST-segment was decreased. Onsets of VPC and VT were delayed, durations of VPC and VT were shortened, especially their combination. Incidences of VPC, VT and VF were decreased. Activity of plasma CK and LDH was decreased, especially their combination. IS, IS/AAR and the morphology of myocardium were improved, especially their combination.

CONCLUSIONRamipril, BQ-123 and combined using these two agents protected myocardium from I/R injury in vivo. The protective effects on delaying onset of VA, shortening duration of VA, decreasing the activities of CK and LDH, decreasing infrarct size and improving morphology of myocardium were better than using ramipril and BQ-123 alone.
