Effect of Danhong injection on serum levels of cystatin C, homocysteine and inflammatory factors in elderly patients with chronic heart failure / 中国生化药物杂志

Objective To analyse the effect of Danhong injection on serum levels of cystatin C (CysC), homocysteine (Hcy) and inflammatory factors in elderly patients with chronic heart failure.Methods Fifty-two elderly patients who were diagnosed with chronic heart failure in our hospital were collected.All patients were randomly divided into experimental group and control group, 26 cases in each group, the control group were given conventional therapy, the experimental group received Danhong injection adjunctive therapy on the basis of the control group.After treatment, the serum levels of CysC, Hcy, nuclear transcription factorκB (NF-κB), interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α), heart function and incidence of adverse reactions were detected in all patients.Results After treatment, compared with control group, the serum levels of CysC and Hcy were lower, the serum levels of NF-κB,IL-1βand TNF-αwere lower in the experimental group, and the levels of left ventricular ejection fraction ( LVEF) and stroke volume (SV) were lower in the experimental group, there were significant difference between two groups (P<0.05).There was no significant difference in the incidence of adverse reactions between the two groups.Conclusion The Danhong injection therapy could significantly reduce the serum levels of CysC, Hcy and inflammatory factors in elderly patients with chronic heart failure,reduce the inflammatory reaction, improve the heart function, and have high safety.

Determination of 17 Characteristic Ingredients of Plant Extracts in Hair Growth Cosmetics by Ultra High Performance Liquid Chromatography / 分析化学

A method was developed for the simultaneous determination of 17 characteristic ingredients of plant extracts, including paeoniflorin, hydroxysafflor yellow A, calycosin_7_glucoside ferulic acid, etc. , in hair growth cosmetics using ultra high performance liquid chromatography ( UPLC ) . Different cosmetic samples were extracted by ultrasonic_assisted extraction with the solvent of methanol/water (4∶1, V/V) solution. After demulsified by the addition of appropriate amount of NaCl and high speed centrifugation, the supernatant was transferred and analyzed with UPLC. The separation was conducted on a Waters reversed phase column of ACQUITY UPLC CSH C18(50 mm×2. 1 mm, 1. 7μm), and the mobile phases were methanol and the solution of 0. 05% phosphate in water. The detection was performed with a photodiode_array ( PDA) detector. The linear range was 0 . 2-25 mg/L with correlation coefficients higher than 0 . 999 . The limits of detection were within 0. 3-1. 5 mg/kg, and the limits of quantification were from 1. 0 to 4. 0 mg/kg. The average recoveries of 17 characteristic ingredients were within 93 . 5%-105 . 0%, with the intra_and inter_day precision ( n=6 ) less than 4. 6%. This method was simple, rapid, with good_repeatability, and had been applied to the analysis of real samples.

Clinical observation of clarithromycin treatment for nasosinusitis after nasopharyngeal carcinoma radiotherapy / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To observe the clinical treatment effectiveness of clarithromycin for naso-sinusitis after nasopharyngeal carcinoma radiotherapy.@*METHOD@#Twenty-four cases of naso-sinusitis after one year nasopharyngeal carcinoma radiotherapy were treated with the oral clarithromycin of small dosage (250 mg everyday). The course of treatment were for 12 to 20 weeks. The treatment effectiveness were evaluated with the chronic naso-sinusitis visual analog quality table mark system (VAS) and Lund-Mackay nasal sinuses CT image mark system before and after treatment.@*RESULT@#The VAS mark and CT image mark have significant deviation (P 0.05) between post treatment and 6 months after drug withdrawal. The treatment effectiveness was judged for very good is 9 cases, for the good is 11 cases and for the bad is 4 cases.@*CONCLUSION@#The clarithromycin of small dosage for long-term treatment of naso-sinusitis after nasopharyngeal carcinoma radiotherapy has positive clinical treatment effectiveness, which is a better treatment method.

Synthesis and Identification of the Antigens for Ciprofloxacin / 中国兽医学报

Hapten-carrier protein conjugates were made using ciprofloxacin (CPFX) and two carrier proteins by 1-ethyl-3-(3- dimethylaminopropyl)-carbodiimide hydrochloride (EDC) method. Ultraviolet spectrophotometry were used to demonstrated that the molecule conjugate ratio of CPFX to ovalbumin (OVA) and bovine serum albumin (BSA) are 6:1 and 13:1 respectively. Nondenaturing gel electrophoresis results revealed that the conjugate band migrates differently from that of the carrier protein alone and of the EDC-treated protein when as few as 6 molecules of CPFX are attached to the carrier protein. The results indicate that nondenaturing gel electrophoresis and ultraviolet spectrophotometry can be employed to analyze the molecule coupling ratio of CPFX to carrier proteins qualitatively and quantitatively.

A STUDY OF ENERGY EXPENDITURE OF MEN WORKED IN THE HOT DESERT ENVIRONMENT / 营养学报

Energy expenditure of five young adults worked in the hot desert environment were measured by the methods of indirect calorimetry in the Wuwei Gansou in July 1989.The results indicated that the basal metabolism rate, the resting metabolism rate and the energy cost of young adults marching in the desert and Gobi (15kg load, at rate of 3.5km/h) were 2.782,3.059,14. 188, 10.305 kJ? m-2?min-1 respectively. It was shown that under the similar conditions energy expenditure marching in the desert was 38% more than in the Gobi.Ambient temperature had a greater effect on energy expenditure but the effect was various at different activities. When at 24.5-38.4℃ during marchi-ng(15kg load),1℃increase in ambient temperature was associated with anincrease of about 0.86% energy consumption. While at 25-33℃ during quiet rest the energy consumption tended to decrease with an increase of ambient temperature. But at 33-40℃ it increased with ambient temperature again. It is suggested that the energy metabolism may be more easily influenced by ambient temperature when the metabolic heat production of human body is increased.The present study recommended the estimation of energy requirement for the adult with a moderate activity in hot desert environment should be approximate 15.062MJ/d
