The subjects of this study were 80 patients who underwent mixed hemorrhoids surgery in our hospital from January to October 2020 (mixed hemorrhoids external and internal ligation, internal hemorrhoids ligation or Xiaozhiling injection) and developed anal edge edema after surgery. According to the order of hospitalization, the patients were randomly divided into treatment group and control group, with 40 cases each. In the control group, blank hot pack was applied on the basis of anorectal No. 1 lotion for prevention and treatment of anal edge edema after operation; in the treatment group, hot pack of Traditional Chinese medicine was applied on the basis of anorectal No. 1 lotion for prevention and treatment of anal edge edema. The course of treatment was 7 days. The edema subsidence and postoperative pain scores were observed in both groups. Results: The scores of anal edema and pain in the treatment group were significantly lower than those in the control group (P < 0.05), and the significant efficiency and total effective rate in the treatment group were significantly better than those in the control group, with statistical difference (P < 0.05). Conclusion: Chinese medicine hot election package is effective in treating postoperative anal edema of mixed hemorrhoids, and the method is simple and suitable for clinical promotion.
This paper uses the method of system dynamics to study the risk factors of PPP project. First of all, on the basis of reading the relevant literature, identify the existing risks of highway PPP project, and establish the stock flow chart of highway PPP project risks. Then, the system dynamics model is used to simulate the project risk. The results show that the operation risk, completion risk and construction risk have a greater impact on the whole PPP project risk system; secondly, the key risk factors affecting the operation risk, completion risk and construction risk are analyzed. Finally, in view of the risk problems existing in the PPP project of expressway, countermeasures and suggestions are put forward. All participants of the project should pay attention to and prevent the risk, reduce the negative impact of the risk, so as to obtain the expected benefits.
