ABSTRACT
Objective To study the effectiveness,side effects and safety of glucosamine chondroitin sulfate calcium (Keylid(R)) tablets for osteoarthritis of the knee.Methods To review the clinical data of 103 cases of primary knee osteoarthritis who had been treated between March 2013 and February 2014.The intervention group included 53 cases (23 males and 30 females with an age of 71.0 ± 9.1 years) who received Keylid(R) tablets (2 tablets twice per day) accompanied with exercise therapy for 24 weeks;the control group included 50 cases (22 males and 28 females with an age of 69.8 ± 8.8 years) who received placebo (2 tablets twice per day) accompanied with exercise therapy for 24 weeks.No NSAIDs,calcium or other articular dietary supplements were taken by the 2 groups during the study period.T-test was used to analyse the results.Results After treatment,the range of knee motion for the intervention group (123.27° ± 10.22°) was significantly larger than that for the control group (116.34° ± 8.76°),and the average pain visual analogue score after 40 m walking for the former (2.92 ± 0.36) significantly lower than that for the latter (3.30 ± 0.22) (P ＜ 0.05).There were no significant differences between the 2 groups in Western Ontario and McMaster Universities Arthritis Index,time for 40 m walking or circumference of the knee (P ＞ 0.05).No side effects were observed in either group during the study period.Conclusion Keylid(R) tablets complemented with exercise therapy may reduce pain and improve knee function with no adverse events in the patients with knee osteoarthritis.
ABSTRACT
PURPOSE: The long non-coding RNA H19, a conservatively imprinted gene, acts as a molecular sponge for the let-7 family, which has been identified as a set of tumor suppressors. However, the combined prognostic value of H19 and let-7a signature in breast cancer patients remains unclear. METHODS: In this research we assessed the prognostic value of the combined H19 and let-7a signature in breast cancer patients by retrospectively reviewing that data of 79 patients who underwent neoadjuvant chemotherapy; we also investigated the expression and function of H19 in breast cancer cell lines in vitro. Survival data were calculated using the Kaplan-Meier method and compared using the log-rank test. Univariate and multivariate survival analyses were conducted using the Cox proportional hazards regression method. As determined using X-tile, the optimal cutoff value for the risk score to assess progression-free survival (PFS) based on the combined signature was –0.1. RESULTS: Patients with an overall positive treatment response had higher let-7a and lower H19 levels. In addition, let-7a expression was negatively correlated with H19 expression. Patients with a risk score of >–0.1 had shorter overall survival and PFS. In vitro data showed that chemoresistant cell lines exhibit higher H19 and lower let-7a levels and knockdown H19 restores paclitaxel sensitivity. CONCLUSION: Our results suggest that the combined let-7a and H19 signature is a novel prognostic factor for breast cancer patients treated with neoadjuvant chemotherapy.

Objective To summarize radiofrequency cather ablation (RFCA)of tachycardias with right sid-ed accessory atrioventricular pathway in 7 patients with persistent left superior vena cava (PLSVC). Methods RF-CA for right sided accessory atrioventricular pathway in 7 patients with PLSVC was carried out . Coronary sinus ac-cess was performed through the left subclavian and the left femoral vein respectively. Swartz sheath was used during ablation if neccesary. Results There was no siginificant differences in fluoroscopy time between the left subclavian approach and the left femoral vein approach[(2.8 ± 0.6)min vs (3.2 ± 0.3)min, P>0.05)]. No recurrence of ac-cessory pathway conduction was found during a mean follow-up of (23 ± 11) months. The mean discharging time and fluoroscopy time were (312 ± 67)s and (17 ± 5)min respectively. Conclusions Although RFCA of right sided accessory atrioventricular pathway in patients with PLSVC shows specialities in cather manipulation , mapping and ablation, high successful results can be achieved by experienced physician.
ABSTRACT
Objective To explore the short and long-term therapeutic effect of helicobacter pylori (Hp) eradication and patho-genic role of Hp infection in the irritable bowel syndrome(IBS) and slow transit constipation(STC) .Methods 98 patients with pos-itive Hp infection which determined by 13C or 14C breath test ,suffered with either the IBS or STC and with concomitant dyspep-sia ,were treated with 7 days regimen of Hp eradication .All cases were re-examined with the 13C or 14C breath test one month after treatment and then divided into Hp positive group and Hp negative group according to the positive or negative Hp infection .And both groups were scored on the change of the habitual defecation and the stool consistency before one day and one month after Hp eradication .Results Hp infection in 87 cases was successfully eradicated ,11 cases failed .Among the Hp positive group ,the total effective rate decreased in comparison with before ,one day ,one month after Hp treatment (P<0 .05) .And among the Hp negative group ,the highest therapeutic effect was found in the diarrhea-IBS and lowest in the STC was found in the first day after treatment (P<0 .05) .Compared with the first day after treatment ,both IBS and STC showed significantly decreased therapeutic effect one month after Hp treatment(P<0 .05) .Conclusion Hp eradication couldn′t induce long term therapeutic effect in IBS and STC , which indicate Hp infection plays a minor role in the pathogenesis of both IBS and STC .The short term improvement of the defeca-tion and the stool consistence in some patients may relate to the change of the gut microbiota .

ABSTRACT
ObjectiveTo assess the effectiveness of tele-medicine and self-management goal(SMG) setting technique used in the diabetes management in the community setting.Methods It is a control-group study.415 type 2 diabetic residents were recruited from the Shanghai Wuliqiao community based on existing medical records.The subjects were divided into two groups,the study group was cared by general practitioners (GPs) specialists cooperation through the tele-medicine mechanism,the other was a control group.For the study group,a cooperation pathway between community health care centers and general hospitals were established.Standardized training and guidelines were provided to community health workers,regarding the setting of management goals of blood glucose and blood pressure,treatment plan,patient education,and SMG techniques.Fasting blood glucose ( FBG ) and 2 h postprandial blood glucose (2hBG) in the study group were monitored,followed by community health workers visiting monthly with seminars for diabetes education.At the baseline and the 12tb month,FBG,2hBG,HbA1C,blood pressure,triglyceride,total cholesterol,body mass index,waist-hip ratio were determined in each group.A survey was conducted to evaluate the costs of diabetes treatments,the knowledge base related to their disease,lifestyle,and the awareness of the new care model.The rates of achieving the goal of blood glucose,blood pressure,and HbA1Ccontrol were calculated.Internet case discussion between GPs-Specialists and referral to certain specialists were implemented when some patients did not reach the control goal.ResultsBy the 12 month follow up,FBG,2hBG,HbAIc,blood pressure of the study group were lower than the baseline,and as well as the control group with statical significance (P＜0.05).There are other improvcments:diabetes knowledge (29.1％ vs 5.5％ ),healthy diet (9.6％ vs -10.4％ ),blood glucose monitoring (30.3％ vs 10.8％ ),support for diabetes care in community (35.7％ vs 9.4％ ),and the preference of the new model (63.8％ vs 17.9％ ) with statistical significauce (P＜0.01 ).As for the medical costs,the study group's monthly costs were consistently lower than the control's.( -3.39Yuan vs 32.26 Yuan,P＜0.05).ConclusionsThe new diabetes care model based on GPs-Specialists tele-medicine and SMG in community opens the door to the community based care model formulation in regard to the health quality and costs control.The deployment of more technologies and management techniques could be explored further to improve the outcomes of community based chronic disease care model.
ABSTRACT
The corona-like spikes or peplomers on the surface of the virion under electronic microscope are the most striking features of coronaviruses. The S (spike) protein is the largest structural protein, with 1,255 amino acids, in the viral genome. Its structure can be divided into three regions: a long N-terminal region in the exterior, a characteristic transmembrane (TM) region, and a short C-terminus in the interior of a virion. We detected fifteen substitutions of nucleotides by comparisons with the seventeen published SARS-CoV genome sequences, eight (53.3%) of which are non-synonymous mutations leading to amino acid alternations with predicted physiochemical changes. The possible antigenic determinants of the S protein are predicted, and the result is confirmed by ELISA (enzyme-linked immunosorbent assay) with synthesized peptides. Another profound finding is that three disulfide bonds are defined at the C-terminus with the N-terminus of the E (envelope) protein, based on the typical sequence and positions, thus establishing the structural connection with these two important structural proteins, if confirmed. Phylogenetic analysis reveals several conserved regions that might be potent drug targets.
