Objective: To observe the application effect of double‐tube negative pressure drainage in the repair of refractory wounds. Methods: From January 2020 to April 2023, 50 patients undergoing refractory wound repair in the Department of Burn and Plastic Surgery of Jingjiang People's Hospital, Jiangsu were selected. According to different treatment methods, they were divided into an observation group and a control group, with 25 patients in each group. The observation group was treated with double‐tube negative pressure drainage inside and outside the wound, while the control group was treated with negative pressure drainage inside the wound. By two‐week observation, the wound healing status and complication rate after treatment, as well as the wound bacterial clearance rate, wound pain score and patient satisfaction 3, 7 and 14 d after treatment were compared between the two groups. Statistical analysis was carried out to determine the efficacy. Results: After treatment for two weeks, the observation group showed a higher grade A healing rate (92% vs. 60%, X2 = 7.018, P = 0.008), a higher wound bacterial clearance rate (100% vs. 76%, X2 = 6.818, P = 0.03), a lower pain score (1.44 ± 0.51 vs. 2.36 ± 0.49, t = ‐6.53, P < 0.01), a higher patient satisfaction score (8.48 ± 0.96 vs. 6.64 ± 0.95, t = 6.80, P < 0.01), and a lower complication rate (8% vs. 40%, X2= 7.018, P = 0.008) compared with the control group. Conclusion: Double‐tube negative pressure drainage has a significant application effect in the repair of refractory wounds. It can accelerate wound healing, shorten treatment time, effectively eliminate bacteria, relieve wound infection, reduce complications, alleviate pain and improve patient satisfaction. Therefore, the application, promotion and research of double‐tube negative pressure drainage should be strengthened in clinical practice. [ABSTRACT FROM AUTHOR]

Reforms in the score reporting system play an important part in the scientific transition of college entrance examination evaluation system. Reporting standard scores is commonly adopted in many countries and especially in the developed countries, hut it was short-lived in our country. Presently, intensive studies on the advantages and disadvantages of different scoring systems will make a positive contribution to talent evaluation and selection. This paper starts from a comparison between original scores and standard scores. Then, by analyzing statistically the data from the college entrance examination in Jiangsu Province, it investigates the change in percentile rank when original scores are converted into standard scores. Finally, it examines standard score's positive influence upon the scientific transition of examination evaluation system. It is found that the application of standard scores, compared with original scores, can effectively reduce the negative effects of non-pilot-test task writing, better meet the target of assessment, and optimize the procedure of college admission. It can also be used to assess students' progress and the education outcomes in different regions. [ABSTRACT FROM AUTHOR]

In order to improve the coastal saline–alkali soil in north Jiangsu Province, the effects of a newly-developed ameliorant was compared with gypsum and cow manure in field trials in coastal saline soil in Dafeng County, China. Measurements included soil electrical conductivity, pH, soil nutrients, the plant ( Salicornia europea L.) growth and ion concentration in stems and roots. The three ameliorants and their combinations improved soil physical and chemical properties and increased the plant height and stem diameter in the order of cow dung > gypsum > new ameliorant. During the experimental period, the soil electrical conductivity of the optimum combination decreased initially and then increased, but was lower than that in the other treatments. Compared with the control,the pH value in the optimum treatment increased by 10.4%, 9.2% and 5.2% in 0–5, 5–20 and 20–40 cm soil layers, respectively. The content of soil organic matter in the three soil layers increased by 22%, 28% and 10%, respectively. The total potassium content in different soil layers increased by 23%, 26% and 26%, respectively. In the optimal treatment, the height of S. europea increased by 32% and stem diameter by 20% compared with control. The K + and Ca 2+ concentration in roots and stems of S. europaea was significantly higher in the optimum treatment compared with control. The optimum combination (in t/ha) was: the new ameliorant 45, gypsum 18 and cow dung 300. [ABSTRACT FROM AUTHOR]
