Research results showed that from the formation of Nansihu Lake, the change of the pollution could be divided into four phrases. At the early phrase of the formation, the organic matters of the lake mainly derived from the exotic matters and had a close relation to the effect on the water and sands from the Huanghe (Yellow) River. At the middle and late phrases of the development, the endogenous matters of the lake became the main and stable source of the organic matters. The overflow of the Huanghe River, the excavation of the Grand Canal and the cut of trees caused the changes of the historic pollution. In recent 20 years, the modern industrial pollution from the organic matters and heavy metals has an increasingly heavy tendency.展开更多
Objective: to evaluate the effect of OSCE (Objective Structured Clinical Examination) model in experimental teaching of pancreatic surgical nursing.

Methods: fifty-six nursing students (2019.01-2020.12) were selected and divided into group A (experimental teaching of traditional pancreatic surgery nursing) and group B (OSCE model comprehensive experiment course) according to computer flow grouping method, with 28 cases in each group. Comparison and analysis of the two groups of autonomous learning ability, assessment results, assessment recognition. Results: (1) autonomous learning ability (self-management ability, information ability, learning cooperation ability, learning reflection ability, total score of autonomous learning): group B > group A (p < 0.05);(2) assessment results (scores of nursing assessment station, nursing diagnosis and planning station, nursing operation station and health education station): group B > group A (p < 0.05);(3) assessment of recognition (interest in learning, ability to analyze and solve problems, communication skills, practical skills, theoretical knowledge and nursing safety awareness): group B > group A (P < 0.05). Conclusion: the application of OSCE model in experimental teaching of pancreatic surgical nursing is time-effective, and has a clear promotion effect on the improvement of nursing students autonomous learning ability and assessment results. Moreover, the assessment of nursing students has a high degree of recognition, is easier to accept by nursing students, and is worthy of optimization.展开更多

Method: from October 2020 to May 2021 to the school clinic cold treatment students selected 40 people, they are divided into equal two groups, a group for observation group, a group for experimental group, a group before mushroom polysaccharide treatment, a group after the capsule treatment. After a period of treatment, the total response rate, symptom duration, and mean changes in TH, TS, TH/TS were compared between the two groups. Mean value changes were contrasted. Results: the total response rate of the experimental group was 95%;the total response rate of the observation group was 60%, thus it can be seen;the total response rate of the experimental group taking Zhenqi Fuzheng capsule was significantly higher than that in another group receiving mushroom polysaccharide tablets, and the experimental group taking Zhenqi Fuzheng capsule on average with 5.4±0.6d cough symptoms disappeared;the average time of headache symptoms was 5.0±0.8d;the average time of the disappearance of runny nose symptoms was 5.1±0.2d;the disappearance of all three clinical symptoms was shorter on average than in the observation group taking shiitake polysaccharide tablets. In addition, the average value of the experimental group was better than that of the observation group. A P <0.05 was statistically significant. Conclusion: the application of Zhenqi Fuzheng capsule treatment to prevent cold can effectively enhance the immunity of patients, and can obtain a good treatment effect, and patients recovery speed is relatively fast.展开更多
