Objective:To establish the quality standard of Fuzhengkangliu pills to further improve the quality. Methods:A TLC method was used for the qualitative identification of Rhizoma Polygoni Cuspidati, Radix Salviae Miltiorrhizae, Radix Astragali Mongoli-ci, Radix Angelicae Sinensis and Rhizoma Chanxiong. Moreover, baicalin was determined by HPLC. Results: The TLC spots were clear and specific. The linear relationship of baicalin was good within the range of 31-310 μg·ml-1 , and the average recovery was 101. 11% (RSD=1. 26%,n=9). Conclusion: The method is simple, accurate, reliable and reproducible, which can be used for the quality control of Fuzhengkangliu pills.

Objective:To improve the quality of Yangxueyufa granules and establish the quality standard. Methods:A TLC method was used for the qualitative identification of Radix Polygoni Multiflori,Fruetus Lyeii,Radix Rehmanniae,Radix Salviae Miltiorrhizae and Fruetus Ligustri Lucidui. Moreover,peoniflorin was determined by HPLC. Results:The TLC spots were clear with highly specificity. The linear relationship of peoniflorin content was good within the range of 14. 3- 286. 0μg·ml-1(r =0. 999 4),and the average recovery was 96. 61%(RSD = 0. 86% ,n = 9). Conclusion:The method is simple,accurate and reliable with good reproducibility,which can be used for the quality control of Yangxueyufa granule.

Objective The existing Quality Standards for Qianliean Capsules lack the quantitation control item and therefore cannot completely reflect the quality of the preparation .This study aimed to establish the methods for qualitation and quantitation of Qianliean Capsules . Methods Thin-layer chromatography ( TLC) was used for the qualitative identification of Radix Salviae miltior-rhizae, Rhizoma curcumae, and Glycyrrhiza uralensis in Qianliean Capsules .The content of hesperidin was determined by high-per-formance liquid chromatography ( HPLC) , and the method of determination was systematically evaluated . Results TLC spots were clear with a strong specificity .The content of hesperidin showed a good linear relationship within the range of 11 .56-310 .00μg/mL (r=0.999 5), with a mean recovery rate of 99.55% and relative standard deviation of 1.93%. Conclusion The qualitation and quantitation methods we established were simple , accurate and reliable , with a good reproducibility , and can be used for the quality control of Qianliean Capsules .

Objective Former standards for Yishen Pills only identify angelica root , astragalus root and ligustrum lucidum by thin layer chromatography ( TLC) and there is no test for the content of effective components .The study was to improve the quality of Yishen Pills by perfecting the quality standards . Methods We determined the content of specnuezhenide in Yishen Pills by high-per-formance liquid chromatography(HPLC), with a mobile phase of MeOH-Water, a chromatography column of Agilent TC-C18(2) (4.6 × 250 mm, 5μm), a flow rate of 1.0 mL/min, a column temperature of 25℃, a detection wavelength of 224 nm, and a sample loop volume of 10μL. Results The linear relationship of specnuezhenide content was good in the range of 15.375μg/mL~246.000μg/mL.The relative standard deviation of precision experiment , stablity experiment and repeatablity experiment was 0.44%, 0.95%and 2.65%re-spectively.The average recovery was 99.60%.The qualified standard for specnuezhenide in Yishen Pills was ≥0.3 mg/g. Conclusion The method is simple , accurate and reliable , with good reproducibility , and it is applicable for the quality control of Yishen Pills .

Objective To compare the efficacy between intramedullary nail and plate in the internal fixation for distal tibial shaft fractures in adults.Methods A retrospective analysis was conducted of the 49 patients with distal tibial shaft fracture who had been treated by internal fixation with intramedullary nail or plate at Department of Orthopaedics,The First People's Hospital of Neijiang from September 2014 to September 2018.They were 26 males and 23 females,aged from 19 to 71 years (average,42.3 years).According to the AO/ ASIF classification,there were 34 cases of type 43A1 and 15 cases of type 43A2.There were 7 open and 42 closed fractures.Of them,23 received intramedullary nailing and 26 steel plating.The 2 groups were compared in terms of intraoperative blood loss,operation time,hospitalization time,fracture healing time,The American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score,infection and fracturemalunion.Results The 2 groups were comparable because there were no significant differences in the preoperative general data between them(P ＞ 0.05).The intraoperative blood loss in the intramedullary nail group (160.3 mL ± 15.2 mL) was significantly greater than that in the plate group (110.5 mL ± 13.4 mL) (P ＜ 0.05).There were no significant differences between the 2 groups in operation time,hospitalization time,fracture healing time or AOFAS ankle-hindfoot scores at the final follow-up (P ＞ 0.05).There were no significant differences between the 2 groups either in the rates of malunion,infection or internal fixation failure (P ＞ 0.05).Five cases in the intramedullary nail group reported painful discomfort in the front of the knee joint while 7 cases in the plate group postoperative discomfort due to plate protrusion.Conclusions Both intramedullary nail and plate are effective treatments of adult distal tibial fracture.However,in order to minimize the risk of infection,intraoperative maneuvers should be as careful and gentle as possible,repeated violence be avoided and soft tissues be carefully protected.
