Objective To investigate the clinical effectiveness and safety of Chinese medicine fumigation-washing therapy in treating talipes equinus denervated ulcer induced by tethered cord syndrome(TCS) . Methods A total of 21 qualified patients were randomized into fumigation-washing group (N=12) and antibiotics group (N=9). Patients of fumigation-washing group were given fumigation-washing therapy with the self-prescribed Chinese medicine, and antibiotics group was given intravenous dripping of sensitive antibiotics. The treatment lasted for 7 continuous days. The clinical efficiency of the two groups was evaluated after treatment, and the period of preparing for surgery was recorded. The changes of ulcer area and ulcer surface exudate volume in the two groups were observed before and after treatment. And the changes in blood routine examination, hepatic and renal function, and immune function of the fumigation-washing group were monitored. Results(1) The total effective rate of fumigation-washing group was 83.3％, and that of the antibiotics group was 77.8％, the difference being insignificant (P>0.05). (2) The ulcer area and ulcer surface exudate volume in both groups were significantly decreased after treatment (P<0.05 compared with those before treatment), and the decrease in the fumigation-washing group was superior to that of the antibiotics group(P < 0.05).(3) The period of preparing for surgery in the fumigation-washing group was(7.75 ± 1.71)d, shorter than(11.56 ± 4.39) d in the antibiotics group, the difference being significant(P < 0.05).(4) There were no statistically significant differences in the hepatic and renal function, and immunoglobulin and complement levels in the fumigation-washing group before and after treatment (P > 0.05). (5) The average daily hospitalization fee in the fumigation-washing group was (47.98 ± 5.17) yuan, less than (227.88 ± 43.24) yuan in the antibiotics group, and the difference was significant between the two groups (P < 0.05). Conclusion Chinese medicine fumigation-washing therapy is effective, safe and practical in treating talipes equinus denervated ulcer induced by TCS, and the therapy has the advantages of decreasing exudation, promoting ulcer healing, reducing hospitalization fee, shortening the period of preparing for surgery, and decreasing the incidence of infection.

This study was aimed to establish an HPLC method for simultaneous determination of the content of echinacoside, acteoside and isoacteoside in Total Cistanchis glycosides Capsules. Waters C18 column (4.6 mm ×150 mm, 5 μm) was used with the mobile phase of methanol-0.1% formic acid at a flow rate of 1.0 mL·min-1. The detection wavelength was set at 330 nm. The column temperature was maintained at 30℃ . The results showed that the linear ranges of echinacoside, acteoside and isoacteoside were in the range of 27.792-277.92 μg·mL-1 (r = 0.9996,n = 6), 2.4184-24.184 μg·mL-1 (r = 0.9996, n = 6), 5.106-51.06 μg·mL-1 (r = 0.9998, n = 6). The average recoveries of three components were in accordance with the determination requirement. It was concluded that the method was simple and accurate, which can be used in the content determination of echinacoside, acteoside and isoacteoside in Total Cistanchis glycosides Capsules.

This study was aimed to establish a method for simultaneous determination of seven anions and organic acids in Huo-Xue Tong-Luo (HXTL) injection by HPCE. With tartaric acid as the internal standard, separation was performed on an uncoated fused silica capillary (50 μm × 64. 5 cm, 56 cm of effective length). The 14 mmol·L-1 potassium acid phthalate and 0.1 mmol·L-1 hexadecyl trimethyl ammonium chloride were selected for the running buffer solution (pH 5.6). The separation voltage was -16 kV. The detection wavelength was set at 210 nm. The column temperature was maintained at 25 ℃ . The sample was injected at 50 mbar×4 s. The results showed that
calibration curves of chloride ion, sulfuric acid root ion, formate ions, malic acid, succinic acid, iodate ion and acetic acid ions showed good linear relationship 41.4-248.2 μg·mL-1 (r = 0.999 3), 12.5-74.8 μg·mL-1 (r = 0.999 8), 18.2-109.1 μg·mL-1 (r = 0.999 8), 20.3-121.6 μg·mL-1 (r = 0.999 5), 17.2-103.1 μg·mL-1 (r=0.999 1), 17.6-105.6μg·mL-1 (r=0.999 6), 51.6-309.6μg·mL-1 (r=0.999 7), respectively. The average recoveries were 102.6%, 97.3%, 102.2%, 99.0%, 99.2%, 97.8%, and 103.4%, respectively. The RSD were 1.7%, 2.0%, 1.6%, 2.6%, 2.1%, 2.9%, and 1.0%, respectively (n = 6). It was concluded that the method was accurate and reproducible. It was suitable for the determination of anions and organic acids in HXTL injection.

OBJECTIVE：To study the effects o f CYP2C9*3 gene polymorphism on therapeutic efficacy of benzbromarone in lowering uric acid and its hepatotoxicity. METHODS ：A retrospective study was conducted to analyze the relevant clinical indicators and genotypes of 196 gout patients who received benzbromarone and CYP2C9*3 gene polymorphism test in Wuhan third hospital from Jan. 2018 to Sept. 2019. RESULTS ：Among 196 patients，179，15 and 2 patients with CYP2C9*3 genotypes * 1/*1， *1/*3 and * 3/*3 genotypes were found ，respectively，and the distribution of each genotype was in line with Hardy-Weinberg balance（P＞0.05）. Before treatment ，there were no significant differences in the levels of UA ，Scr，ALT，AST and CRP between *1/*1 genotype and * 1/*3+*3/*3 genotype（P＞0.05）. After 4 weeks of treatment ，the UA ，Scr，CRP levels of patients with * 1/*1 genotype as well as the UA and CRP levels of patients with * 1/*3+*3/*3 genotype were significantly reduced ，the UA level of patients with * 1/*1 genotype was significantly lower than that of patients with * 1/*3+*3/*3 genotype（P＜0.05 or P＜0.01）. The ALT and AST levels had no obvious changes in patients with different genotype before and after treatment ，and they were in the normal range. No serious abnormal liver function was observed during the treatment. CONCLUSIONS ：Therapeutic efficacy of benzbromarone in lowering uric acid in gout patients with CYP2C9*3 genotypes * 1/*1 genotype is better than that of * 1/*3 and * 3/*3 genotypes. However ，the gene polymorphism may be not associated with its hepatotoxicity.
