Objective:To analyze the distribution of clinically isolated fungal strains and their resistance to common antifungal drugs in Shandong province.Methods:Through the Shandong Children’s Bacterial & Fungal Drug Resistance Surveillance and Research Collaborative Network, a total of 1 030 fungi were collected in 46 hospitals of Shandong province from January 1 to December 31, 2018. The source and type of strains were analyzed, and antifungal drug sensitivity tests were performed by using the micro-dilution method. Whonet 5.6 and SPSS 22.0 were applied to analyze the data.Results:The overall main strains were Candida albicans (38.74%, 399/1 030), Candida tropicalis (16.99%, 175/1 030) and Candida parapsilosis (16.41%, 169/1 030); the main fungi strains in child patients were C. albicans (52.50%, 63/120), C. parapsilosis (12.50%, 15/120) and C. tropicalis (9.17%, 11/120); the main fungi strains in adult patients were C. albicans (36.37%, 331/910), C. tropicalis (17.03%, 155/910) and C. parapsilosis (15.27%, 139/910). The isolation rate of main Candida strains from January to March and August to December was much higher than that of other months. The drug resistance rates of C. albicans to fluconazole and voriconazole were 7.14% and 7.43%, respectively, and the drug resistance rates to itraconazole were 50.44%. The resistance rates of C. tropicalis to fluconazole, voriconazole and itraconazole were 29.05%, 23.29% and 48.65%, respectively. The sensitivity rates of C. parapsilosi to fluconazole, voriconazole and itraconazole were 93.06%, 93.75% and 94.44%, respectively. Candida glabrata showed a dose-dependent sensitivity rate of 2.33% to fluconazole. Analysis of 244 blood fungi strains showed that non-candida albicans bacteremia accounted for 70.08%. In the pathogen spectrum covering 92.22%, fluconazole was sensitive to 64.65% of the pathogens, voriconazole was 68.88%, and amphotericin B was 88.75%. After quantification, the effective rates of fluconazole, voriconazole and amphotericin B in the clinical treatment of fungal bacteremia were 70.10%, 74.69% and 96.23%, respectively. Among them, the sensitivity rate of voriconazole to C. tropicalis was lower than that of fluconazole. Conclusions:Candida is the main clinical fungus isolates in hospitals of Shandong province. The resistance rate of C. tropicalis to azole antifungal drugs is on the rise, and the sensitivity of other Candida species to clinically used antifungal drugs is basically stable.

64 eight-week-old female rats were randomly divided into to 8 groups with four in medical treatment group and four in control group. The treatment groups were trained by progressive intensifying endurance swimming, and the medical-taken groups were fed with lycium for 5 weeks, and then the changes of the liver cellular free radical metabolism and ultrastructure were investigated. The effects of lycium and endurance training on liver cellular ultrastructure and free radical metabolism in rats were then explored. The results showed that exhaustive swimming time of rats could be extended by endurance training, and that exhaustive swimming time of rats could significantly be prolonged after taking lycium, and the ultrastructure of liver cell with taking lycium was more complete than that without taking lyceum. Lycium could cause significant increase of the activity of liver superoxide dismutase (SOD) and the ratio of SOD/MDA, and meanwhile cause decrease of the content of liver MDA. Conclusions can be drawn that lycium and endurance training can improve exercise capacity of rats, and lycium has certain protecting functions of the liver.

Objective To know the performance of CT in Xuzhou, and provide references for the allocation optimization of medical resources in effective using of CT in Xuzhou. Methods All hospitals that have large medical equipment in Xuzhou were investigated and the cost, payment and benefit of 42 CT are analyzed. Results The median of cost is 142.6 yuan per person. The median of payment is 277.0 yuan per person. The median of annual net profit is 652 thousand yuan per CT. Conclusion The payment is higher than the cost of CT in Xuzhou. The ratio of profit is 120.8%, but half of CT can't take back of the investment in regular time.
