ABSTRACT
Astragali Radix is commonly used as bulk medicinal materials. Chinese Pharmacopoeia contains about 150 compound preparations of Astragali Radix, but the sample preparation method under the determination of Astragali Radix content in Chinese Pharmacopoeia is tedious and time-consuming, not convenient for the test of a large number of samples. Therefore, it is of great significance to simplify the sample preparation method and improve the practicability of the method for the quality control of Astragali Radix and its preparations. In this study, ultrasonic extraction method was used instead of heated reflux extraction, and solid phase extraction method was used to enrich and prepare the samples. A set of practical quality evaluation method was established for Astragali Radix slices and standard decoction, greatly shortening the sample preparation time and improving the accuracy of the method. The results of Astragali Radix standard decoction analysis showed that the transfer rate of calycosin 7-O-β-D-glucospyranoside,(96.5±28.7)%, had great variation, which was found to be related to the conversion of mulberry isoflavone glucoside into calycosin 7-O-β-D-glucospyranoside during the preparation of standard decoction. The transfer rates were(59.4±14.4)% and(101.3±12.3)% for calycosin and astragaloside Ⅳ respectively, which were relatively stable. Therefore, it is suggested that Astragali Radix slices and water decoction preparations should be evaluated by using calycosin and astragaloside Ⅳ as the quality evaluation index. The results provide a scientific and practical method for quality control of Astragali Radix slices and its standard decoction, and also provide scientific evidence for quality evaluation of the preparations.

BACKGROUND: Chronic rhinosinusitis (CRS) is one of the most common diseases in China. The incidence of CRS in the Chinese urban population is between 5 and 15%. It is difficult to cure with traditional surgery. Endoscopic sinus surgery is the first choice for the treatment of CRS. Compared with developed countries, the development of the clinical pathway of endoscopic sinus surgery in China is still unclear. OBJECTIVES: The aim is to explore whether the clinical pathway of endonasal sinus surgery is better than the traditional one in the Chinese population. METHODS: We searched PubMed, Embase, the Cochrane Library, Web of Science, ClinicalTrials.gov, SinoMed, China National Knowledge Internet, Wanfang database of Chinese Journals, and VIP database of Chinese Journals. The last retrieval date was August 24, 2018. Review Manager 5.3 software was used for comprehensive quantification data analysis. RESULTS: Fourteen papers involving 1,882 patients were included in this study. The results showed that compared with the traditional pathway, the clinical pathway can effectively shorten the average number of hospitalization days (mean difference, MD = -2.00, 95% CI: -2.50, -1.49). In total, 10 of the 14 papers, with a total of 1,500 patients, proved that the clinical pathway can effectively reduce the hospitalization costs of patients (standard mean difference, SMD = -3.15, 95% CI: -4.20, -2.10); 11 of the 14 papers, with a total of 1,488 patients, proved that the clinical pathway can effectively improve patients' knowledge of health (95% CI:1.03, 1.09); and 7 of the 14 papers, with a total of 810 patients, proved that the clinical pathway can effectively improve patient satisfaction (95% CI:1.10, 1.20). CONCLUSIONS: Our systematic review and meta-analysis support the use of the clinical pathway in patients with endoscopic sinus surgery in China.

Objective To investigate the status quo of Otolaryngology services in county-level hospitals in Ningxia,to know its developmentbottlenecks and shortcomings,and to provide suggestions for promotion of Otolaryngotogy medical service ability in county-level hospitals in Ningxia.Methods By cluster sampling method,and through questionaire survey,investigating and analyzing the actuality of Otorhinolaryngology in county-level hospitals in Ningxia.Results The current status of Otorhinolaryngology in county-level hospitals in Ningxia was lower than the standard of county-level hospitals.The number of personnel and equipment is seriously insufficient.Few medical technology can be carried out.The number of outpatients and discharged patients increases.The number of outgoing patients increases.Conclusion The medical service ability of Otorhinolaryngology in county-level hospitals in Ningxia is low.It is suggested to formulate development plans and to innovate development way;to develop human resources,and to upgrade technical level;to use information platform,and to joint construction of academic alliances.
