Objective To set up the quality standard of Shenbai concentrated pills. Methods Radix Astragali, Radix Paeoniae Rubra and Rhizoma Imperatea in Shenbai concentrated pills were identified with the method of TLC. The concentration of salvianolic acid B was determined with the method of HPLC. Results For TLC, the chromatogram spots of Radix Astragali, Radix Paeoniae Rubra and Rhizoma Imperatea were well separated and without interference in their negative controls. Quantitative analysis of HPLC showed that the average recovery of salvianolic acid B was 99.74% (RSD=2.08%) with the RSD of precision, reproducibility and stability was 1.74%, 1.19% and 1.70%, respectively. Conclusions The methods set up by this study are easy, accurate and stable, and can be used as the quality control standard of Shenbai concentrated pills.

Objective To explore the effect of applying problem-based learning(PBL)in clin-ical anesthesiology demonstration for clinical undergraduates. Methods Eighty-nine 2009 clinical undergraduates were divided into two groups:experimental group and control group. Students in ex-perimental group received PBL while those in control group received traditional teaching. The effect was evaluated according to the results of case examination and investigation table. The results were analyzed by X2 test. Results Most students (42/45) answered questions correctly in experimental group while only 30 of 44 students(30/44)did in control group(P<0.05). Concerning the results of investigation,PBL had more advantages than traditional teaching method in the following 5 aspects:self-studying ability(86.7%,39/45),clinical thinking ability(73.3%,33/45),information seeking ability (75.6%,34/45),expressing ability (82.2%,37/45),communicating between students (75.6%, 34/45)(P<0.05). Conclusions PBL has evident advantages in anesthesiology clinical demonstration. It can inspire students,cultivate abilities,enhance critical thinking and finally improve teaching effect.

BACKGROUND:Bone marrow mesenchymal stem cel s are likely to repair renal injury by differentiating into renal parenchymal cel s. OBJECTIVE:To explore the effect and mechanism of bone marrow mesenchymal stem cel s in the renal repair after mesangial proliferative glomerulonephritis. METHODS:Thirty Sprague-Dawley rats were randomized into normal group, model group and treatment group (n=10 per group). Model group and treatment group were treated with tail vein injection of mouse anti-rat monoclonal antibody Thy1.1 to prepare mesangial proliferative glomerulonephritis models. One week after modeling, rats in the treatment group were given 2×106 bone marrow mesenchymal stem cel s via the tail vein, and rats in the other two groups were given the same volume of normal saline. Two weeks after transplantation, urinary protein, urea nitrogen, creatinine levels were detected;hematoxylin-eosin staining was used for observing pathological changes of the renal tissue under microscope;and the expression of transforming growth factor beta 1 was detected by immunohistochemistry method. RESULTS AND CONCLUSION:The levels of urinary protein, urea nitrogen and creatinine as wel as the expression of transforming growth factor beta 1 in the renal tissue arranged in descending order were listed as fol ows:model group>treatment group>control group, and there were significant differences among three groups (P<0.05). In the model group, diffuse glomerular hyperplasia was observed with the presence of increased extracel ular matrix, partial glomerular sclerosis, and interstitial infiltration of inflammatory cel s;in the treatment group, glomerular hyperplasia, mesangial proliferation and inflammatory cel infiltration were al mitigated compared with the model group. Therefore, bone marrow mesenchymal stem cel transplantation may contribute to renal repair after mesangial proliferative glomerulonephritis, by inhibiting overexpression of transforming growth factor beta 1 in the kidney.

A capillary electrophoretic method was developed for the separation of enantiomers of naphthylgly-cidic ether(NGE). Several cyclodextrins(CDs) were applied as the chiral selectors and it was found that the ionic modified highly sulfated cyclodextrin(HS-β-CD) could give satisfactory enantioselectivity. In addition,the effects of the pH value of the buffer system,the concentration of the HS-β-CD,capillary temperature and the running voltage on the chiral separation were investigated systematically. The result showed that under the optimized conditions of pH 2. 5,20 mmol/L H_3PO_4-triethanolamine buffer containing 2% highly sulfated cyclodextrin ( HS-β-CD) at capillary temperature 20℃ in the reversed polarity voltage of - 18 kV,the enantiomers of naphthylglycidic ether were baseline separated. This method is simple,precise and can be applied to the chiral separation of naphthylglycidic ether enantiomers and determination of enantiomers excess(ee,% ).

Ancient literature of ethnic medicine , as a concentrated expression of the ethnic culture of Chinese medicine , has a distinct regional and national character . In this paper , the questionnaire , interview , literature and other methods , were applied to elaborate the research situation of ethnic medicine ancient literature in Sichuan province from the aspect of the literature resources investigation, excavation arrangement, and etc. Ac-cording to the different national medical status differences , we pointed that the national pharmaceutical develop-ment ignored literature research . And we proposed recommendations on how to protect and use the ethnic medicine ancient literature . This paper provided a scientific basis for the further promotion of ethnic medicine literature excavations work in Sic huan province .

Objective To summarize the medical rescue of Chinese Government Medical Team (Chongqing) in Nepal earthquake region in order to explore the work pattern of transnational medical rescue,and improve the rescue efficiency.Methods From the experience about the post-earthquake medical rescue of Chinese Government Medical Team (Chongqing) in Nepal in 2015,several aspects were worthy to summarize such as the establishment of medical team,the layout of camp site,the work algorithm and process,with the analysis of injury feature and outcome of treatment.Results Under the setting of efficient organization and rational assignment of professional work,special working rules,the mutual transfer treatment and multi-disciplinary treatment were employed for 737 emergency patients.Of them,128 patients were hospitalized (including 63 patients completely recovered,56 patients were of clinical improvement,and 9 patients were critically ill transferred to other hospital for advanced treatment),and post-traumatic complication occurred in 48 cases without death.In addition,148 operations were carried out successfully.Conclusions The earthquake disaster has specific feature such as suddenness,a host of casualties and poor rescue conditions,and overseas rescue is with the presence of the language barrier,the difference in living habit,and the lack of coordination with local rescue system,therefore,rationally assigning personnel and resources and establishing work pattern with flexibility,orderly and good communication are the key to promote the efficiency of transnational medical rescue for the injured patients in earthquake region.

Objective To validate the 2010 Edition kidney cancer TNM staging in China.Methods Data were collected from 695 operated kidney cancer patients from Jan.1981 to Dec.2003.These patients were staged based on the 6th Edition and 7th Edition kidney cancer TNM staging system,respectively.The Kaplan-Meier method,log-rank test and Cox regression models were used to analyze survival functions.Results Compared to the 6th edition staging system,the number of patients with stage T3a,T4changed from 98 to 88,from 29 to 42 in new staging system,respectively.According to the 6th edition staging system,there was significant difference comparing perirenal fat invasion only with adrenal gland only ( P =0.08 ),there was no significant difference comparing Gerota fascia invasion ( stage T4 ) only with adrenal gland invasion only (P =0.412).According to the new staging system,there was no significant difference comparing stage T2b with stage T3a ( P =0.714). Conclusion The new kidney cancer staging system has better staging specificity and clinical application results in high accuracy.
