BACKGROUND:Liver fibrosis is a kind of chronic and active disease that is caused by various causes and characterized by the excessive accumulation of extracelular matrix. At present, use of Chinese herbs for the treatment of hepatic fibrosis has obvious advantages. Salvia miltiorrhiza has been shown to be highly effective in the treatment of hepatic fibrosis. However, the underlying mechanism needs further investigation. OBJECTIVE:To investigate the effects of TanshinoneⅡA on the expression levels of transforming growth factor-β/Smads signaling pathway related factors transforming growth factor-β, bone morphogenetic protein 7, Smad6 and Smad7 in the liver tissue of rats with hepatic fibrosis. METHODS:SD rats were randomly divided into three groups (n = 10): normal control, model and TanshinoneⅡA-treated groups. Rats in the model and TanshinoneⅡA-treated groups were subtaneously injected with olive oil-diluted 10% CCl4 ( 5 mL/kg) twice a week, 8 weeks in total, to build rat models of hepatic fibrosis. Four weeks after hepatic fibgrosis induction, rats in the TanshinoneⅡA-treated group received subtaneous injection of TanshinoneⅡA til eight weeks. Rats in the normal control group were subcutaneously injected with olive oil. RESULTS AND CONCLUSION: Western blotting and reverse transcription-polymerase chain reaction (RT-PCR) detection showed that in the model group, the expression of transforming growth factor-β in the rat liver tissue was significantly increased (P < 0.01) and the expression of bone morphogenetic protein-7, Smad6 and Smad7 was significantly decreased (P < 0.01) compared with the normal control group. TanshinoneⅡA could obviously reverse the expression of those factors above-mentioned (P < 0.01). The results suggest that TanshinoneⅡA can be used for treatment of hepatic fibrosis by decreasing the expression of transforming growth factor-β and increasing the expression of bone morphogenetic protein-7, Smad6 and Smad7.

"Vessels Collateral Theory", as the inherit and development of "blood vessels" in Huangdi Neijing, is a systematic system by integrating severe vascular diseases.

Objective To explore the clinical results of the arthroscopic acromioplasty in the rotator cuff repair.Methods Sixty-five patients (42 males and 23 females) to receive suture bridge repair under the arthroscopy between May 2012 and May 2014 were selected and randomly divided into an experimental group and a control group.The experimental group was given suture bridge repair with acromioplasty,while the control group underwent the suture bridge repair without acromioplasty.The time of operation was recorded.The range of motion (ROM) of the shoulder,the UCLA shoulder scoring system (ULCA) score,American orthopedic surgeon scoring system (ASES) score,the visual analogue scale (VAS) score and Constant score were observed 3 and 12 months after the operation.Results There were no significant differences in age,sex and the affected side between the two groups.Significant differences were found between the two groups in the duration of the operation (t=-18.5,P＜0.05).There were no significant differences in the ROM and the ULCA,ASES,VAS and constant scores of the shoulder 3 and 12 months after the operation.Conclusion No significant differences were found in the ROM and the shoulder function scoring between giving acromioplasty under the arthroscopy or not.However,the operation time of undergoing acromioplasty under the arthroscopy was longer.

Objective Myelodysplastic spndrome (MDS) patients' chromosome aberrations were detected by CC and FISH method respectively,to establish standard FISH platform of diagnosis of MDS,to compare the differences of FISH and CC in the detection of MDS chromosome aberrations.Methods Chinese MDS patients fulfilled with the Vienna minimum diagnostic criteria were tested by CC and FISH method,and the patients' clinical data was collected at the same time.Results The standard FISH platform of diagnosis of MDS was established successfully,including probe combination of-5/5q-,+8,-7/7q-,20q-,-Y,the success rate was 100 ％.In 83 cases of MDS,chromosome aberrations rate detected by two methods was 42.2 ％,30.1％ of CC method and 33.7 ％ of FISH method,the accordant diagnostic rate was 76.1％.FISH had higher positive rate than CC method (29.6 ％ vs 18.6 ％,P =0.049) in the IPSS intermedian-risk 1 group,but lower positive rate in IPSS intermedian-risk 2 group (62.5 ％ vs 81.2 ％,P =0.036).There were 11 (19.0 ％) cases of clonal chromosome aberrations detected by FISH method but not detected by CC method,in which 10 (90.9 ％) cases were intermedian-risk 1 group (IPSS grouping).Evaluate IPSS by FISH and CC respectively,the accordant rate was 86.7 ％.Evaluate IPSS by CC alone will result in 3 patients (3.6 ％)decline in risk stratification,and evaluate IPSS by FISH alone will result in 8 patients (9.6 ％) decline in risk stratification.There were 35 (42.2 ％) cases of chromosome aberrations detected by the two methods,including 13 (15.7 ％) cases of complex karyotype and 22 (26.5 ％) cases of single abnormal karyotype.The most common chromosomal aberration was +8,a total of 9 (10.8 ％) cases,followed by abnormalities of chromosome 7,a total of 7 (8.4 ％) cases.Conclusion The study has established standard FISH platform of diagnosis of MDS,the method is stable,sensitive and rapid.FISH technology joint CC technology can improve the patients with MDS chromosome aberration detection rate.Compared to CC,FISH technique can improve the detection rate of the intermedian-risk 1 IPSS grouping MDS patients.Because of limited probe,FISH technique can not entirely replace the role of CC method in MDS,but can complement each other.

OBJECTIVETo investigate the clinical application of the ureteral dilation catheter combined with the balloon catheter under the ureteroscope in the treatment of urethral stricture in men.

METHODSUnder the ureteroscope, 45 male patients with urethral stricture received placement of a zebra guide wire through the strictured urethra into the bladder and then a ureteral dilation catheter along the guide wire, followed by dilation of the urethra from F8 initially to F14 and F16. Again, the ureteroscope was used to determine the length of the strictured urethra, its distance to the external urethral orifice, and whether it was normally located. An F24 balloon catheter and then a metal urethral calibrator was used for the dilation of the strictured urethra. After removal of the F18-F22 urethral catheter at 8 weeks, the urinary flow rate was measured immediately and again at 3 months.

RESULTSAll the operations were successfully performed without serious complications. The maximum urinary flow rate was (13.3-29.9) ml/s (mean [17.7 ± 3.2] ml/s) at the removal of the catheter and (15.2-30.8) ml/s (mean [19.8 ± 3.9] ml/s) at 3 months after it. Smooth urination was found in all the patients during the 6-24 months follow-up.

CONCLUSIONThe application of the ureteral dilation catheter combined with, the balloon catheter under the ureteroscope is a good option for the treatment of male urethral stricture for its advantages of uncomplicatedness, safety, effectiveness, few complications, less pain, high success rate, and repeatable operation.
