OBJECTIVE: To evaluate the therapeutic effect of Zangfukong suppository on the experimental vaginitis.METHODS:The experimental rats were equally assigned to 6 groups: normal control group,model control group,gyno-daktarin(0.12 g?kg-1) group,three Zangfukang groups(0.33 g,0.17,and 0.08 crude drug? kg-1).Candida albicans solution was injected into the vigina of the estrous rats to establish colpomycosis model.The effect of Zangfukang suppository on the infection rate of candida albicans was observed.The bacterial vaginitis model was established by injecting the mixture bacteria of Neisseria gonorrhoeae,staphylococcus aureus and escherichia coli into the vagina of rats,and the effect of Zangfukang suppository on the gonococcal infection rate.RESULTS: After local application of Zangfukang suppository for 7 consecutive days for treatment of colpitis mycotica of rats,the infection rates of candida albicans were significantly lower in medium-dose and high-dose groups than in the model control group(P

ObjectiveTo evaluate the expression of interleukin-1 β ( IL-1β) ; interlenkin-8 ( IL-8 ) ; tumor necrosis factor-α,(TNF-α) in induced sputum in different stages of stable chronic obstructive pulmonary disease (COPD) and heath smoking controls.Methods90 healthy smoking controls and 100 stable COPD patients were enrolled.The levels of IL-1β,IL-8 and TNF-α in induced sputum were detected by radioimmunoassay.ResultsThe levels of IL-1β,IL-8 and TNF-α in stable COPD patients were much higher than those in healthy smoking controls (P =0.000).There are an inverse correlation between FEV1 and levels of IL-1 β,IL-8 and TNF-α in induced sputum (r=-0.678,-0.752,-0.615,all P＜0.05).ConclusionIL-1β,IL-8 and TNF-α may play important roles in the mechanism of airway inflammation in stable COPD.The levels of IL-1 β,IL-8 and TNF-α in induced sputum may be a marke of severity of airway inflammation in stable COPD.

Objective To explore a quick and feasible method of screening malaria parasite by using a Sysmex XE-2100 hematology analyzer though alarm information on high eosinophil count and atypical eosinophil distributions in the WBC scattergram. Methods Sysmex XE-2100 hematology analyzer was used for complete blood cell analysis. Microscopic review was used when high eosinophil count and atypicaleosinophil distributions in the WBC scattergram were found. If the review showed normal eosinophil cells, wecontinued to focus on red cell for searching malaria parasite. Results Among 1 501 specimens showing higheosinophil counts and atypical eosinophil distributions, nine cases with normal eosinophil cells were indisaccordance with the hematology analyzer, six of them showed high eosinophil count in the Sysmex XE-2100 hematology analyzer, whose distribution was located close to neutrophil clusters in scattergram. The otherthree had an abnormal WBC scattergram. There was no gap between eosinophil clusters and neutrophilclusters, which brought no classified results. But all the nine specimens had been found the trophozoite,schizont and merozoite in blood smears. Conclusions There were great possibility of the existence of themalaria parasite in specimens when hematology analysis showed high eosinophil count and atypical eosinophildistributions in the WBC scattergram in a Sysmex XE-2100 hematology analyzer, although these alarm wasnot comfirmed by microscopic review. This method provides not only a simple and reliable way for quickscreening malaria parasite but also has a great value in preventing the undetected ratio on malaria parasite.

Objective To explore the diagnosis and treatment of disseminated cryptococcosis involving the biliary tract and the central nervous system. Methods The clinical data of one child with disseminated cryptococcosis involving biliary tract and central nervous system were analyzed retrospectively. The related literatures were reviewed. Results A 6-year-old boy presented with jaundice, hepatic dysfunction and convulsions. The surgical treatment was performed. The pathological biopsy showed cryptococcal infection, cryptococcal capsular polysaccharide antigen latex agglutination test in serum and cerebrospinal fluid were positive and cerebrospinal fluid ink staining was also positive. After antifungal treatment, the symptoms were relieved and no sequelae existed during the follow-up period. Conclusion Disseminated cryptococcosis simultaneously involving the biliary tract and the central nervous system is rare in children.

Objective To probe into the total number and development status of respiratory physicians in China, and to analyze existing problems, for reference in making strategy and policy decisions in professional development of respiratory physicians in the country. Methods The basic information of China′s healthcare institutions and healthcare manpower in 2015 were provided by the Statistics Center of the National Health Commission. The number of respiratory specialists and their profile, drawn from such basic information, were subject to descriptive statistics. Results In 2015, there were 2.729 million medical practitioners ( including assistant doctors ) nationwide, 30.3 thousand among whom being respiratory physicians, accounting for 1.11% of the total. Among these respiratory physicians, practicing respiratory physicians account for 87.1% , respiratory physicians with a master degree and above account for only 19.7% , respiratory physicians with over 10 years of working experience account for 65.8% , respiratory physicians with senior titles account for only 21.4% , and 89.4% of the respiratory physicians work in general hospitals. Conclusions By the criteria of specializing in respiratory specialty over five years and being attending or above, the number approximates 14. 6 thousand nationwide. If practicing ( assistant) physicians specializing in respiratory specialty are also included, the number may hit 30. 3 thousand. Such a number, compared with other specialties, may be sufficient, yet their competence is far from satisfactory. Therefore it is imperative to build a standardized pulmonary medicine fellowship training system for their competence improvement.

Objective:To investigate the effects of different frequency sling exercise therapy (SET) on the balance of trunk control and walking ability in stroke patients.Methods:A total of 90 patients with stroke who were admitted to the Department of Rehabilitation Medicine, Union Hospital of Tongji Medical College, Huazhong University of Science and Technology, from January 2018 to December 2018, received sling exercise therapy on a routine basis and were divided into 1 time/Day low frequency group, 2 time/Day medium frequency group, 3 time/Day high frequency group, 20 min/time, for a total of 3 months.After 1, 2 and 3 months, trunk control test (TCT), Berg balance scale(BBS), functional ambulation classification (FAC) and modified Barthel Index (MBI) were used to evaluate the three groups of patients.Results:There were significant differences in TCT, BBS, FAC and MBI between the low, middle and high frequency groups (all P < 0.05). The scores of TCT in the low, middle and high frequency groups were (36.21±6.31), (42.51±4.33), (49.52±4.90) and (41.23±6.31), (50.32±8.32), (58.12±7.23) respectively, and the scores of BBS were (15.11±4.31), (19.69±5.86), (24.56±8.74) and (21.43±5.37), (27.61 ± 7.50), (33.81±6.99) respectively, compared with those before treatment )The scores of (24.69±9.33), (22.84 ± 10.11) and (9.32 ± 3.11), (9.504.10), (9.47 ± 3.73) were significantly improved, and the differences between the high frequency group and the low frequency group and the medium frequency group were statistically significant (all P< 0.05), but there was no statistically significant difference between the three groups after three months of training ( P> 0.05). There was no significant difference between fAC and MBI in the low, medium and high frequency group, but there was no significant difference between the two groups after training for 2 and 3 months There were significant differences between fAC ((1.84±0.41), (2.39±0.44), (3.29 ± 0.33) and MBI ((27.32 ± 9.33), (34.45 ± 9.21), (44.77 ± 10.27) and (41.33±11.21), (52.73±12.31), (75.94±13.22)). There was significant difference between the high frequency group and the low frequency group ( P< 0.05). Conclusion:Multiple sling exercise therapy in one day can further improve the balance of trunk control and walking ability of stroke patients, and shorten the course of disease.

Objective: To investigate the feasibility of echocardiography-guided closed-chest repeated intraventricular blood sampling in mice, and to clarify the maximum blood volume that can be collected by this method, and whether the method can be used for long-term repeated blood collection in mice. Methods: Twenty-four male C57BL/6J mice (10-14 weeks old) were divided into the terminal experiment group (n=4, for investigating the maximum blood amount that could be sampled at one time), the repeated 0.5 ml blood collection group (n=10, sampling 0.5 ml whole blood each time, once every two days for consecutive 4 weeks), and the repeated 0.75 ml blood collection group (n=10, sampling 0.75 ml whole blood each time, once every two days for consecutive 4 weeks). High-frequency echocardiography was used to display the largest section of the left ventricle, guiding the insulin syringe needle through the thorax into the left ventricle for blood collection. In the repeated 0.5 ml blood collection group, echocardiography was used to detect the cardiac structure and function before blood collection, three minutes after blood collection, and one week after the last (the 14th) blood collection. Results: We successfully performed echocardiography-guided closed-chest intraventricular blood sampling, with an average operating time (88±19)s per mouse, and a maximum blood volume (1.43±0.11)ml per mouse. In the repeated 0.5 ml blood collection group, heart rate, left ventricular ejection fraction, left ventricular fractional shortening, left ventricular end-diastolic dimension and left ventricular posterior wall end-diastolic thickness remained uncganged before the first blood collection and after 4 weeks of repeated blood collection (all P>0.05). No death in the repeated 0.5 ml blood collection group. However, in the 0.75 ml blood collection group, two mice died before the end point. Conclusions The echocardiography-guided closed-chest intraventricular blood sampling is a safe, minimally invasive, convenient and efficient method, and can be used repeatedly for long-term blood collection in mice.
