The clinical study of middle and old age patients with knee osteoarthritis treated by abdominal acupuncture combined with sodium hyaluronate injected in intraarticular / 中国基层医药

Objective To explore the clinical efficacy of knee osteoarthritis treated by abdominal acupuncture combined with sodium hyaluronate injected in intraarticular.Methods 120 patients with knee osteoarthritis were randomly divided into observation group and control group,60 patients in each group.The observation group was treated by abdominal acupuncture combined with sodium hyaluronate injected in intraarticular.The control group was treated with intraarticular injection of sodium hyaluronate alone.Results After a follow up of 6 months, the total effective rate of the treatment group was 95.00%,which was higher than 78.33% of the control group, the difference was statistically significant (x2=7.21,P<0.01).Conclusion Abdominal acupuncture combined with intraarticular injection of sodium hyaluronate is a good way to treat middle and old age patients with knee osteoarthritis.

Study on type selection of ambulance helicopter / 医疗卫生装备

To lay a foundation for the type selection of the ambulance helicopter. The type selection was explored from the aspects of platform selection, rescue environment and service requirements, analyzing the rescue in the helicopter and the tendency of the ambulance helicopter in foreign countries and China. The types of the am-bulance helicopter were determined as the specific and modified ambulances, with the considerations such as operation environment, flight performance, cabin structure, onboard equipment, cabin configuration, fixation device and protection. Specific ambulance helicopter is supposed to be based on small- or mediate-sized platform, while the modi-fied ambulance helicopter is supposed to be based on large or heavy platform.

Biothermokinetic studies on four properties of traditional Chinese materia medica——Comparison of different preparation properties of Coptidis Rhizoma by microcalorimetry / 中草药

Object To probe into the objectivity and authenticity of four properties (cold, heat, warm, and cool) of raw Coptidis Rhizoma (RCR) and their preparations from biophysics and biochemistry. Methods Microcalorimetry was used to obtain the metabolic growth power-time curve of bacteria affected by the total alkaloid in different preparations of RCR and biothermokinetic parameters. Combined with the records of ancient herbal literatures, the influence of properties by different preparations to RCR were synthetically evaluated. Results All the effective total alkaloid in different preparations of RCR can restrain the Escherichia coli growth and metabolism in different level. Drugs, such as Coptidis Rhizoma Stir-fried with ginger juice (CRGJ), Coptidis Rhizoma stir-fried with wine (CRW), and Coptidis Rhizoma stir-fried with Fructus Evodiae (CRFE), with a little Warm Property can decrease the multiplication rate constants of E. coli index and increase heat output in growth metablism remarkably, while the drugs, such as RCR, Coptidis Rhizoma stir-fried with vinegar (CRV), and Coptidis Rhizoma stir-fried with gallbladder juice (CRGBJ), with a little Cold Property can decrease the multiplication rate constants and increase heat output a little. There was a stable difference between them. Conclusion Microcalorimetry is a new and useful mean for the study of the properties of tradition Chinese medicine.
