1.Comparison of Polyphyllins Content in Paris Polyphylla Planted under Walnut Forest in Different Areas of Yunnan Yangbi
China Pharmacist 2016;19(10):1983-1985
Objective:To compare 4 polyphyllins contents in Paris polyphylla planted under walnut forest in different areas of Yun-nan Yangbi. Methods:Paris polyphylla samples planted under walnut forest were collected in different areas of Yunnan Yangbi, and according to the methods described in Chinese Pharmacopoeia (2015 edition), the contents were determined. Results:Yunnan Yangbi different planted in Paris polyphylla four polyphyllins content of each sample there were significant differences between samples were cultivated in imitation of the wild forest, but the cultivation of varying lengths of time, the growth period of 4 to 5 years in Paris polyphylla four polyphyllins content was significantly higher than that of 3 born in Paris polyphylla. Conclusion: Four kinds of Paris polyphylla saponin content of the samples have significant differences with the Paris polyphylla growth of ecological environment, growth period and the same species living on different populations, the genetic background.

BACKGROUND: Using color Doppler ultrasonography, renal graft size, appearance, structure, and blood flow distribution can be observed. Through the use of blood flow display technique, blood flow perfusion of renal graft can be accurately observed to assist diagnosis and differential diagnosis of complications following renal transplantation. OBJECTIVE: To observe the hemodynamic characteristics during different periods of acute renal transplant rejection, summarize its specific manifestations through analyzing different reaction of two dimensional and color Doppler flow imaging (CDFI) during renal transplantation in order to get valuable index on acute rejection of renal transplantation.DESIGN, TIME AND SETTING: Comparative observation was performed at the Jinan University and First Hospital of Shenzhen University between January 2003 and January 2007.PARTICIPANTS: A total of 299 patients undergoing renal transplantation were divided into normal allograft group (n=236) and acute rejection group (n=63) according to renal allograft function.METHODS: The systolic peak flow rate, end-diastolic flow rate, mean flow rate, pulsatility index and resistance index of main renal artery and arcuate artery in patients of two groups were compared. MAIN OUTCOME MEASURES: Renal allograft arterial inner diameter and hemodynamics of two groups.RESULTS: Compared with normal allograft group, the blood flow perfusion was reduced at acute rejection, which could not reach cortex margin, blood velocity was decreased at the diastolic phase, pulsatility index and resistance index were increased (P < 0.05). CONCLUSION: Color Doppler ultrasound, as a convenient, economical and noninvasive technique, provides the reliable evidences for the renal artery pulsatility index and resistance index in clinic, and also is valuable for the acute rejection early diagnosis of renal allograft.

The anterior cruciate ligament (ACL) injury is a common sports injury that has a significant impact on knee function and patients′ mobility. With the popularity of national fitness campaign in China, the incidence of ACL injury is increasing year by year. Currently, there still lacks clinical standards or guidelines on how to choose appropriate treatment methods, surgical plans and rehabilitation protocols for ACL injury. In order to timely reflect the new treatment concept of ACL injury, standardize its diagnosis and treatment and improve the curative effect, the Sports Medicine Society of Chinese Research Hospital Association and the Editorial Board of Chinese Journal of Trauma organized domestic orthopedic and sports medicine experts to formulate the "clinical evidence-based guideline for the diagnosis and treatment of anterior cruciate ligament injury (2022 version)" based on the level of evidence-based medicine and in compliance with the principle of scientificity, practicability and advancement. The present guideline includes 12 recommendations for the diagnosis, treatment and rehabilitation of ACL injury in order to provide guidance and assistance for the clinical diagnosis and treatment of ACL injury in China.
