Objective To describe rural people's perceptions of schistosomiasis and other dis eases, and to explore the relevance of these perceptions to disease control programs in rural areas of China. Methods A cross sectional study was conducted in Yingjiang Village, Anhui Province,China. Anthropological and epidemiological re search methods, including focus group discussions,in depth interviews, questionnaires and stool tests, were used. Results People identified various infectious diseases, such as schistosomiasis, hepatitis, hemorrhage fever, hookworm diseases, as cariasis and infection skin diseases. The knowledge of villagers regarding schistosomiasis and other diseases was not inconsiderable but not entirely accurate. Local illness taxonomy usually resulted from the concepts as to the causation of diseases. Local people thought there were about eight categories of factors that might cause diseases. These categories were worms, the unbalance of hot cold faetors, over work and starvation, "hot poison", dirty water and food, psychological factors, supernatural factors and pesticides. Conclusion Health education, improving sanitation and safe water supply may play much important roles in improving health of rural people.

Objective To investigate the effect of femoral design on anterior knee pain after patella reserving total knee arthroplasty. Methods From 15 January to 15 February 2002, 44 patients and 59 knees were followed up. Among these patients, 40 patients and 51 knees were included in this study, the rest cases were excluded for one or more of following factors. 1)Knee flexion was less than 80 degrees;2)Radiography showed that there were surgical errors such as: femoral component flexion more than 30, anterior femoral cortex notching, and patellar baja or alta. According to current generally accepted criteria, femoral components were classified as "Patella Friendly" group and "Patella Unfriendly" group. The percentage and severity of anterior knee pain was measured with patient visual pain index and Knee Society Functional Score System. Results The aforementioned two groups consisted of "Patella Friendly" group 21 knees and "Patella Unfriendly" group 31 knees. The average anterior knee pain score of "Patella Friendly" group and "Patella Unfriendly" group was respectively 1.58 (0-8) and 3.32 (0-6). The percentage of pain free patients of the two groups was 64% and 9%. There was significant statistical difference between the groups in terms of anterior knee pain score (t=4.642, P

Objective To investigate the analysis of Symbicort in stable stage of chronic obstructive pulmonary disease treatment and intervention. Methods 80 patients with chronic obstructive pulmonary disease in stable period from June 2014-2016 year in May in our hospital were randomly divided into control group and experimental group, 40 cases in each group. The control group of patients with the use of simple Symbicort treatment and routine nursing care to patients, patients in the experimental group using Symbicort combined with Bailing Capsule for treatment, and the implementation of targeted nursing intervention measures, compare the effect of two groups of patients and nursing satisfaction. Results the clinical treatment of patients in the experimental group the total efficiency 95.0%, nursing satisfaction was 97.5%, the control of clinical patients in the treatment group the total effective rate was 80.0%, nursing satisfaction was 87.5%, the experimental group was significantly higher than the control group, the difference was statistically significant (P<0.05). Conclusion Chronic In the stable period of obstructive pulmonary disease, the combination of Xin Yi capsule combined with Bailing capsule can effectively improve the pulmonary function of patients and improve the clinical therapeutic effect, and is worthy of popularization and application in clinic.

[Objective]To measure the change of anatomic configuration of proximal tibial after high tibial osteotomy and probe its clinical consequences.[Method]From 2001 to 2005,there were 59 knees of 35 patients with medial unicompartmental osteoarthritis treated with closing-wedge high tibial osteotomy.Anatomic configuration of proximal tibia were measured both pre and postoperatively on radiographs.They included posterior slope angle of proximal tibia,tibial angle,lateral shift of articular surface of proximal tibial and level of the joint line.The alteration of the above features was calculated and analyzed statistically with paired t test.[Result]The mean tibial posterior slope angle were(8.9??2.6?)preoperatively and(5.0??2.3?)postoperatively.The tibial posterior slope angle was averagely decreased about(3.9??1.7?).Tibial angle were(99.1??4.3?)and(91.1??3.8?)before and after high tibial osteotomy respectively.Lateral shift of articular surface of proximal tibial were(46.2?3.6)% and(53.1?3.9)% in pre and postopratively.Level of joint line was(41.2?3.6)mm and(38.0?3.2)mm in pre and postopratively.Statistical analysis indicated that there was significant difference of posterior slope angle or tibial angle or lateral shift of articular surface of proximal tibial or level of joint line between pre and post operative(P

Objective:To develop the evaluation index system for clinical teaching quality supervision of nursing undergraduates.Methods:Based on the theory of Donabedian's structure-process-outcome quality model, literature review, semi-structured interviews, Delphi method and Analytic Hierarchy Process were adopted to determine the teaching quality supervision index system for clinical nursing interns.Results:After two rounds of expert consultation, questionnaire response rates were 92.86%(26/28), 100.00%(26/26); expert authority coefficients were 0.871, 0.887 and the two rounds of expert consultation authority coefficient was 0.879; coefficients of variation ranged from 0.00 to 0.15 and 0.04 to 0.12; coordination coefficients ranged from 0.256 to 0.667 and 0.402 to 0.804 ( χ2 values were 60.276-427.571, P<0.01). The final index system consisted of 3 first-level indicators, 9 second-level indicators, and 36 third-level indicators. The analytic hierarchy process was used to determine the weights of all indexes, and the consistency test (CR<0.1) was performed. Conclusions:The construction of the index system for clinical teaching quality supervision of nursing undergraduates is scientific with reasonable weight. It can provide reference for the improvement and reform of clinical nursing teaching work.

In this article, the method of quick and accurate identification ofAstragalus membranaceus (Fisch.) Bge. var.mongholicus (Bge.) Hsiao in different growth years by electronic nose (e-nose) technique and chemical analysis was developed. An e-nose was used to detect the odors ofA. membranaceus. var.mongholicus samples in two-growth-year, seven-growth year and more than a decade growth years for establishing the classification model of response characteristics. Principal component analysis (PCA) and discriminant factor analysis (DFA) were performed to differentiate theA. membranaceus. var.mongholicus samples in different growth years. PCA was performed to investigate the difference in the chemical composition and quality of different growth years inA. membranaceus. var.mongholicus samples. The results of PCA and DFA analyses for e-nose demonstrated that the samples ofA. membranaceus. var.mongholicus in different growth years could be distinguished obviously. The contents of chemical composition were similar in same growth years inA. membranaceus. var.mongholicus and different from different growth years. The results of chemical composition analysis indicated that the identification forA. membranaceus. var.mongholicus in different growth years was significant for the quality control. E-nose technique could identify the samples ofA. membranaceus. var.mongholicus in different growth years rapidly, sensitively and intactly, and could be applied for the quality control of traditional Chinese medicine.
