This paper was aimed to study the effectiveness and safety of TanshinoneⅡA Sulfonate Sodium Injection in the treatment of unstable angina pectoris (UAP). Keywords such as coronary atherosclerotic heart disease, coronary heart disease, unstable angina, chest impediment, cardialgia, TanshinoneⅡA Sulfonate Sodium Injection, tanshinone injection, tanshinoneⅡA sulfonate, unstable, angina, randomized controlled trial (RCT), and clinical trials were searched in CNKI, VIP, Wanfang and Pubmed from the construction of database until October 31st, 2014. The inclusion criteria were RCT with clinical data integrity, similar literature research methods, and good balance between groups. The Jadad score method was used to carry out quality assessment. Meta-analysis was conducted by RevMan5.2 software. Count data was processed by odds ratio (OR). Measurement data was processed with the weighted mean differences (WMD). The 95% confidence interval (CI) was also calculated. The heterogeneity test result of included literatures was P > 0.05. The fixed effects model was used in the meta-analysis. On the other hand, random effect model was used. For the analysis results of more than 10 papers, the funnel plot was used in the analysis of publication bias. The results showed that a total of 34 studies were included. The results of meta-analysis suggested that the total efficiency of conventional treatment plus TanshinoneⅡA Sulfonate Sodium Injection for UAP was [OR = 3.83, 95%CI (3.11, 4.71),P < 0.000 01]. The electrocardiogram improvement rate was [OR = 3.34, 95%CI (2.61,4.28),P < 0.000 01]; plasma viscosity improvement was [WMD = -0.20, 95%CI (-0.38, -0.03),P = 0.03]; high shear viscosity of whole blood improvement was [WMD = -0.67, 95%CI (-0.85, -0.50),P < 0.000 01]; C-reactive protein improvement was [WMD = -2.66, 95%CI (-3.31, -2.00),P < 0.000 01]. It was concluded that the conventional treatment plus TanshinoneⅡA Sulfonate Sodium Injection for UAP had certain clinical effect with no obvious adverse reaction. However, due to the poor quality of the existing research literatures, the results should be further verified by large amount of high quality RCTs.

Objective To compare patellar ring,Kirschner wire tension band and patellar ring plus Kirschner wire in fixation for treatment of patella fractures.Methods A retrospective analysis was conducted on the 285 patients with patellar fracture who had been treated between September 2009 and January 2016.They were 155 men and 130 women,with an average age of 45.5 years (from 18 to 70 years).Their fractures included 176 transverse,28 longitudinal split and 81 comminuted ones.They were divided into 3 groups according to their different internal fixation methods:patellar ring fixation (98 cases),Kirschner wire tension band (92 cases),patellar ring plus Kirschner wire fixation (95 cases).The 3 groups were compared in terms of operative time,intraoperative bleeding,fracture healing time,knee function by B(o)stman score at the last follow-up and postoperative complications.Results The operative time in the patellar ring group(58.9 ±6.4 min) was significantly shorter than in the Kirschner wire group (71.8 ± 7.8 min) and in the patellar ring plus Kirschner wire group (74.4 ± 8.0 min) (P ＜ 0.05).There were no statistical significant differences between the 3 groups in fracture healing time and intraoperative bleeding (P ＞ 0.05).The good to excellent rate of knee function at the last follow-up in the Kirschner wire tension band group was 100.0％ (92/92),significantly higher than in the patellar ring group (90.8％,89/98) and in the patellar ring plus Kirschner wire group (91.6％,87/95) (P ＜ 0.017).There was no significant difference in postoperative complication rate between the patellar ring fixation group (2.0％,2/98),Kirschner wire tension band fixation group (1.1％,1/92) and the patellar ring plus Kirschner wire group (2.1％,2/95) (P ＞ 0.05).Conclusion Internal fixation with Kirschner wire tension band has definite curative effect on patellar fractures,showing the advantages of less operative invasion,fewer postoperative complications,better functional recovery of the affected knee joint,and lower price over the other 2 internal fixation methods.

OBJECTIVEOur research studied the fast-breeding technology of Ardisia crenata sims by using tissue culture and provided the scientific foundation for industry production.

METHODThe effects of axillary buds and plant regeneration of different basic medium, hormones and additives on induction and multiplication were studied.

RESULTThe best culture medium for the induction of axillary buds, which took the stems of A. crenate were as explants, was MS + 6-BA 0.5 mg x L(-1) + NAA 0.1 mg x L(-1), and the best medium for multiplication was MS + 6-BA 2.0 mg x L(-1) + NAA 0.1 mg x L(-1) + KT 0.5 mg x L(-1), the best medium for roots generation was 1/2MS + IBA 0.2 mg x L(-1). We also found that the roots'generation, roots rate and mean number of roots can be promoted by adding 0.2% Ac, and the most suitable ground substance was river sand-perlite-vermiculite (1:1:1) or perlite-vermiculite (1:1). With axillary buds and plant regeneration methode, more than 80% A. crenata sims could be regenerated integratedly.

CONCLUSIONA. crenata sims can be regenerated integratedly and breeded fast by using axillary bud proliferation technology.

Objective: Network pharmacology combines drug and disease targets with biological information networks based on the integrity and systematicness of the interactions between drugs and disease targets. This study aims to explore the molecular basis of Hanshi Zufei formula for treatment of COVID-19 based on network pharmacology and molecular docking techniques. Methods: Using TCMSP, the chemical constituents and molecular targets of Atractylodis Rhizoma, Citri Reticulatae Pericarpium, Magnoliae Officinalis Cortex, Pogostemonis Herba, Tsaoko Fructus, Ephedrae Herba, Notopterygii Rhizoma et Radix, Zingiberis Rhizoma Recens, and Arecae Semen were investigated. The predicted targets of novel coronavirus were screened using the NCBI and GeneCards databases. To further screen the drug-disease core targets network, the corresponding target proteins were queried using multiple databases (Biogrid, DIP, and HPRD), a protein interaction network graph was constructed, and the network topology was analyzed. The molecular docking studies were also performed between the network's top 15 compounds and the coronavirus (SARS-CoV-2) 3CL hydrolytic enzyme and angiotensin conversion enzyme II (ACE2). Results: The herb-active ingredient-target network contained nine drugs, 86 compounds, and 49 drug-disease targets. Gene ontology (GO) enrichment analysis resulted in 1566 GO items (P < 0.05), among which 1438 were biological process items, 35 were cell composition items, and 93 were molecular function items. Fourteen signal pathways were obtained by enrichment screening of the KEGG pathway database (P < 0.05). The molecular docking results showed that the affinity of the core active compounds with the SARS-CoV-2 3CL hydrolase was better than for the other compounds. Conclusion: Several core compounds can regulate multiple signaling pathways by binding with 3CL hydrolase and ACE2, which might contribute to the treatment of COVID-19.

OBJECTIVE：To establish the fingerprint of ethanol extract and acetone extract from Anemarrhena asphodeloides and its different processed products ，and to investigate the spectrum-effect relationship between the fingerprint and the antioxidant activity. METHODS ：HPLC method and HPLC-ELSD method were adopted. The determination was performed on Thermo BDS Hypersil C 18 column with mobile phase consisted of acetonitrile- 0.2％ acetic acid at the flow rate of 1.0 mL/min. The column temperature was 30 ℃，and the detection wavelength was set at 258 nm. The sample size was 10 μL. The determination was performed on XDB-C 18 columnwith mobile phase consisted of acetonitrile-0.1％ acetic acid （gradient elution ）at the flow rate of 0.9 mL/min. The column temperature was 30 ℃ . The temperature of atomizer was 40 ℃ and the flow rare of N 2 was 1.6 mL/min. The sample size was 10 μL. Using mangiferin and timosaponin B Ⅱ as reference ，Fingerprint Similarity Eva- com luation System of TCM Chromatogram （2004A edition ）was adopted to draw the fingerprint of ethanol extract and acetoneextract from 20 batches of A. asphodeloides and its different processed products to confirm common peaks. Using scave nging rate of 1，1-diphenyl-2-trinitrophenylhydrazine（DPPH）radical as index，antioxidant activities of ethanol extract and acetone extract from 20 batches of A. asphodeloides and its processed products were investigated. Using scavenging rate of DPPH radical as dependent variable ，common peak area as independent variable ，PLSR was used to analyze the spectrum-effect relationship of ethanol extract and acetone extract from A. asphodeloides with antioxidantion activity. RESULTS ：Eight peaks （M1-M8）were identified in the fingerprints of ethanol extracts from 20 batches of processed A. asphodeloides . Mangiferin （chromatogram peak M 7）was identified with similarity of 0.389-1.000；seven comon peaks （S1-S7）and timosaponin B Ⅱ（peak S 5）were identified in the fingerprint of acetone extract ，and the similarity was 0.044-0.999. DPPH radical scavenging rate of ethanol extract from 20 batches of A. asphodeloides and its processed products was 21.23％- 81.39％，and A. asphodeloides was significantly lower than salt-processed A. asphodeloides with salt wine-processed A. asphodeloides （P＜0.001）；and that of acetone extract was 49.73％-83.78％，and A. asphodeloides was significantly higher than stir-baked A. asphodeloides with salt ，wine or fire （P＜0.001）. The standardized regression coefficients of peaks M 2-M7 in the spectrum of ethanol extract from A. asphodeloides were all greater than 0，which was positively correlated with antioxidant activity. Only the variable importance projection （VIP）value of peak M 7 was greater than 1，which had an important contribution. The standardized regression coefficients of peaks S 4-S7 in the acetone extract spectrum of A. asphodeloides were greater than 0，and were positively correlated with antioxidant activity. The order of VIP values was peak S 5＞S6＞S4，and the VIP values were all greater than 1. CONCLUSIONS：The fingerprint of the different processed products A. asphodeloides and its antioxidant activity spectral effect relationship were successfully established ；mangiferin（peak M 7）may be the main antioxidant substance of ethanol extract from A. asphodeloides . Timosaponin B Ⅱ（peak S 5），peak S 6 and peak S 4 may be the main antioxidant substance in acetone extract from A. asphodeloides .
