This article elaborated on professional development objectives of traditional Chinese medicine (TCM) clinical teachers and analyzed on the existing teaching ability development foundation of clinical teachers from the trend of clinical practice teaching development.Meanwhile,the article proposed the basic connotation of TCM clinical teachers' teaching ability development based on the construction of the module of clinical teachers' professional ability development and the opening learning environment.

Objective To study the role of Anopheles anthropophagus in malaria transmission and transmission threshold so as to provide basis for vector surveillance and malaria control strategy. Methods Parasitological and entomological methods were used in the investigation at 5 villages of Xinyang City, Henan Province. Results From July to August, 1999, 74 febrile cases (10\^9% of the total population) were examined. Among them 50 were infected, the incidence in the population of surveyed spots was 7\^4%. Active detection was made in another randomly selected two villages and found that the parasite rate in the inhabitants was 2\^0%, and the positive rate of IFA was 8\^4%. Only vivax malaria was detected. An.anthropophagus and An.sinensis were collected, with An.anthropophagus as the predominant one in human dwellings. The estimated man\|biting rate and the human blood index were 4\^9388 and 0\^7858 respectively. The vectorial capacity of An. anthropophagus was 5\^5296. The critical man\|biting rate of An.anthropophagus was 0\^2407 as calculated by the formula (ma=-rlnP/abP\+n) according to Macdonald′s model.The local man\|biting rate was 20 times higher than that of the critical man\|biting rate. Conclusion The results demonstrated that An.anthropophagus is the principal vector in malaria transmission in the area. The findings imply that the critical man\|biting rate is of practicable importance in vector surveillance.

Objective To understand the malaria epidemic situation in Chengdu City,so as to provide the evidence for effec-tively carrying out the malaria elimination work. Methods The data of imported malaria in Chengdu City from 2012 to 2016 were collected from the Disease Surveillance Information Reporting System of Chinese Center for Disease Control and Prevention and analyzed respectively. Results A total of 240 imported malaria cases were reported in Chengdu City from 2012 to 2016. In de-tail,68.75％of the cases were falciparum malaria cases,20.41％were vivax malaria cases,2.50％were quartan malaria cases, 6.25％were ovale malaria cases,and 2.08％were mixed Plasmodium infections. Among them three patients died,with a mortali-ty of 1.25％. All of the cases were infected overseas,among which 224 patients returned from Africa and 16 patients from South-east Asia. The annual average morbidity was 0.28/100000,and there was a significantly difference among annual average mor-bidities(χ2=23.87,P<0.001). There were malaria cases reported in every month,and no significantly difference among sea-sons(χ2=0.833,P>0.05). Conclusion The number of overseas imported malaria in Chengdu City increases year by year. The effective measures to control the overseas imported malaria should be strengthened to consolidate the achievements of malar-ia elimination.

In recent years, the research on boron-containing drugs, especially boric acid drugs, has been increasing gradually.Boron-containing drugs, which have been a new area of research for pharmaceutical chemists in the development of new drugs, play an increasingly important anti-inflammatory, antibacterial, and anti-tumor role.At present, five boron-containing drugs have been approved, many are under clinical trials, and more are under investigation around the world, which has greatly expanded the application of boron in the research of new drugs.This paper introduces the characteristics of boron, and reviews the indications of representative boron-containing drugs in various research stages, their binding mechanisms with targets, and their progress after entering clinical trials, aiming to provide reference for further research on boron-containing drugs.

Objective:To analyze the feasibility of developing clinical pediatrics curriculum for pediatric students at the pre-clinical stage, and to provide a basis for the subsequent curriculum construction.Methods:A total of 90 pediatric medical students were enrolled, including pre-clinical group (G1, third semester of the second year, n=47) and the clinical clerkship group (G2, seventh semester of the fourth year, n=43). A questionnaire survey was conducted to compare the two groups from three aspects: clinical interest, learning methods and learning ability. And 24 and 20 students were randomly selected from the two groups to participate a clinical course respectively. Both of the formative evaluation and in-class test were carried out to compare the learning performance and learning effect between G1 and G2. SPSS 22.0 was used for data analysis. The counting data were described by case number and rate, and the frequency between groups was compared by chi-square test. When the chi-square test condition is not met, Fisher's exact test was performed. Normal distribution test was carried out for measurement data. Two independent sample t test was conducted for the comparison between groups of normal distribution data and Mann-Whitney U test for the comparison between groups of skewed distribution respectively. Results:There was no significant difference in clinical interest and pre-clinical interest between the two groups (Fisher's exact probability method, P=0.252, 1.000). There were partial differences in learning methods: G1 spent more time learning after class ( Z=-2.36, P=0.018), learned more in spare time ( Z=2.53, P=0.011), learned more on the homework ( P=0.020), and had a higher preview rate ( Z=-5.07, P < 0.001). There were also partial differences in learning ability: G2 had better literature retrieval ability ( χ2=10.57, P=0.001); G2 had higher scores on class and extended class performance ( t=-3.18, P=0.004; t=-10.14, P<0.001). In terms of learning effect, G2 scored higher scores on only one multiple choice question ( t=-2.46, P=0.022). Conclusion:The pediatrics students at the pre-clinical stage have certain interest and ability to receive clinical pediatrics courses. Sufficient pre-class preparation and appropriate curriculum design are helpful to the early cultivation of student's clinical thinking.

Objective To explore the relationship between the maximum standardized uptake value ( SUVmax ) of 18 F-fluoromisonidazole ( FMISO) PET/CT and the pathological classification, differentiation, T stage and primary tumor volume of nasopharyngeal carcinoma ( NPC) . Methods A retrospective analysis was performed on 41 patients with NPC (31 males, age 18-74 years;10 females, age 35-67 years) who underwent head and neck 18 F-FMISO PET/CT from 2012 to 2015. The relationship between the clinicopath-ological parameters (pathological classification, differentiation, T stage, tumor volume) of primary lesion and SUVmax were analyzed. Mann-Whitney u test, approximate t test and Spearman correlation were used for data analysis. Results There was no significant difference in SUVmax between non-keratinizing carcinoma and squamous cell carcinoma ( u=183.5, P>0.05) , nor between the differentiated carcinoma and undiffer-entiated carcinoma( t'=-1.23, P>0.05) . SUVmax of T1-T2 primary tumor was significantly lower than that of T3-T4 tumor (1.52±0.43 vs 2.05±0.85; t'=-2.60, P<0.05), and SUVmax was correlated with primary tumor volume ( rs=0.488, P<0.05) . Conclusions The hypoxic degree is related with T stage and primary tumor volume in NPC. The combination analysis of T stage and tumor size will contribute to the assessment of oxygen level and prognosis of primary NPC.
