Abstract: Objective　To study the distribution and influencing factors of hospitalization costs of elderly patients with diabetes in Hainan Province, providing evidence for the relevant governmental departments in the formulation of prevention and treatment strategies for elderly diabetes. Methods Based on the homepage data of medical records of tertiary hospitals in Hainan Province in 2022, the hospitalization costs of elderly diabetes patients in Hainan Province were divided into five grades: lower, low, general, high, and higher. The hospitalization costs of 8 183 elderly diabetes patients in Hainan Province and their influencing factors were analyzed by using an ordered multicategory logistic regression model. Results The hospitalization costs of the elderly patients with diabetes in Hainan Province as a whole showed a right-skewed distribution but followed a nearly normal distribution within the range of 0-50 000 yuan, with a mean value of (10 446.32±10 228.36) yuan. The number of hospitalizations, medical institution visited, type of medical insurance, reimbursement ratio, household registration, gender, age, place of birth, marital status, and work unit were related factors affecting the level of hospitalization costs of elderly diabetes patients in Hainan Province (P<0.05). Compared to the group with ≥4 hospitalizations, the estimated coefficients for the group with 1 hospitalization was (β=-0.728, 95%CI: -0.852 to -0.603, P<0.001), for the group with 2 hospitalizations: (β=-0.359, 95%CI: -0.511 to -0.206, P<0.001), and for the group with 3 hospitalizations: (β=-0.314, 95%CI: -0.495 to -0.133, P<0.001), indicating that fewer hospitalizations significantly reduced hospitalization costs. Compared to those treated in medical institutions in other cities and counties, patients treated in Haikou City had (β=1.137, 95%CI: 1.028 to 1.247, P<0.001), and patients treated in Sanya City had (β=1.046, 95%CI: 0.916 to 1.175, P<0.001), showing that hospitalization costs for patients in Haikou and Sanya cities were significantly higher than those in other regions. Compared to those using commercial health insurance, patients using urban employee basic medical insurance had (β=-0.352, 95%CI: -0.531 to -0.173, P<0.001), those using urban resident basic medical insurance had (β=-0.384, 95%CI: -0.587 to -0.182, P<0.001), and those using the new rural cooperative medical insurance had (β=-0.545, 95%CI: -0.754 to -0.335, P<0.001), indicating that using social medical insurance significantly reduced hospitalization costs. Conclusions Diabetes patients consume a lot of medical and health resources, imposing a heavy economic burden on individuals, families, and society. Early prevention and treatment of diabetes should be implemented, with a focus on the health management of the elderly population to reduce the medical burden of diabetes in the future.

Results The two methods presented no significant differences in bleeding , operation time and hospital stay (P > 0.05);Both groups were fast in postoperative recovery, without any recurrence, atrophy of testis and hydrocele. Conclusions The endoscopic high ligation of internal spermatic veins is equal to open operations for varicocele.

BACKGROUND: The expression of matrix metalloproteinases (MMPs) is enhanced in fibroblasts of aging skin; tripterine and ginsenoside Rd possess immunosuppression and anti-aging effects. Arotinoid ethyl ester can used to treat sun-induced aging skin, which accompanied by many side effects, OBJECTIVE: To discuss the regulation role of ginsenoside Rd, celastrol, arotinoid ethyl ester on MMP-1 and MMP-3 of the cultured fibroblasts of the human dermis in vitro. METHODS: The human dermis circumcision by surgical excision on newborn was obtained from Department of Surgery, Luzhou Medical College, and the informed consent obtained from patients. Culture of fibroblasts were as follow: ①No treatment in the normal control group. ②Radiated with 80 kJ/m~2 ultraviolet and treated by 100mg/L8-methoxypsoralen in the positive control group. ③Treated by ultraviolet radiation+8-methoxypsoralen+arotinoid ethyl ester in the arotinoid ethyl ester group. ④Treated by ultraviolet radiation +8-methoxypsoralen+triptolide in the triptolide group. ⑤Treated byultraviolet radiation+8-methoxypsoralen+ginsenoside Rd in the ginsenoside Rdgroup. The triptolide group was divided into 3 groups with doses of 10, 20, and 40 mg/L. The ginsenoside Rd group was divided into 3 groups with doses of 20, 50 and 100 mg/L. The immunohistochemistry staining of MMP-1 and MMP-3 of the fibroblasts in each group was observed. RESULTS and CONCLUSION: The expressions of MMP-1 and MMP-3 were significantly increased in the positive control group, which had a significant difference to the normal control group (P < 0.05). Compared to the positive control group, the expression of MMP-1 and MMP-3 significantly decreased in the treatment groups (P < 0.05); however, the differences among each treatment groups had no significance (P > 0.05). The results demonstrated that:①Ginsenoside Rd and tripterine exhibit comparably effect on prevent and cure sun-induced aging skin.②The wide ranges of effective concentration lead to little side effect to the body. ③The action mechanisms of ginsenoside Rd, celastrol and arotinoid ethyl ester in preventing and curing sun-induced aging skin is adjusting the expressions of MMP-1 and MMP-3.
