RESUMEN
Objective:To analyze the influential factors of post-stroke depression and investigate the effects of changes in serum bilirubin and high-sensitivity C-reactive protein on post-stroke depression.Methods:A total of 199 patients with stroke admitted to Qinghai Provincial People's Hospital from December 2019 to December 2020 were included in this study. These patients were divided into the Xining urban group (2 000-3 000 meters above sea level; n = 165) and the Xining prefecture and county group (over 3 000 meters above sea level; n = 34) according to their long-term residence. They were also divided into the post-stroke depression group ( n = 56, including 45 patients in the Xining urban group and 11 patients in the Xining prefecture and county group) and non-post-stroke depression group ( n = 143, including 120 patients in the Xining urban group and 23 patients in the Xining prefecture and county group). Related scales were used to evaluate neurologic deficits and the degree of depression in the two groups. Serum levels of total bilirubin, direct bilirubin, and high-sensitivity C-reactive protein were measured in each group. Neurologic deficits and the degree of depression were correlated with serum levels of total bilirubin, direct bilirubin, and high-sensitivity C-reactive protein. Results:Serum levels of total bilirubin, direct bilirubin, and high-sensitivity C-reactive protein in the post-stroke depression group were (19.95 ± 7.22) mmol/L, (3.98 ± 1.49) mmol/L, and (1.40 ± 2.29) mg/L, respectively, which were significantly higher than (16.20 ± 7.61) mmol/L, (3.19 ± 1.62) mmol/L, and (0.63 ± 1.33) mg/L in the non-post-stroke depression group ( t = 3.17, 3.18, 2.35, all P < 0.05). There was a significant difference in serum level of high-sensitivity C-reactive protein between stroke patients with mild and moderate depression and stroke patients with severe depression ( t = 2.48, P < 0.05). Conclusion:Serum levels of bilirubin and high-sensitivity C-reactive protein play an important role in the pathogenesis of post-stroke depression and there is a significant correlation between the two.

Objective:To analyze the influencing factors of the medical insurance balance of hospitalization expenses for gastric cancer surgery patients under DRG payment, for reference for promoting the reform of DRG payment in public hospitals and controlling hospitalization expenses reasonably.Methods:The gastric cancer patients enrolled in the gastroenterology department of a tertiary comprehensive hospital from January to July 2022 were selected as the research subjects. The indicators such as patient age, medical insurance balance, hospitalization expenses and their composition were extracted from the hospital information management system and the medical insurance settlement system a certain city. Descriptive analysis was conducted for all data, and stepwise multiple linear regression was used to analyze the influencing factors of patients′ medical insurance balance. Monte Carlo simulation method was used to simulate different combination scenarios of various influencing factors to analyze the probability of medical insurance balance.Results:A total of 205 patients were contained, including 117 in the medical insurance balance group and 88 in the loss group. The difference in hospitalization expenses and medical insurance balance between the two groups of patients were statistically significant ( P<0.05). The intervention of medical insurance specialists, correct DRG enrollment, parenteral nutrition preparation costs, anti infective drug costs, examination costs, and consumables costs were the influencing factors of patient medical insurance balance ( P<0.05). Through Monte Carlo simulation verification, patients with different cost parenteral nutrition preparations, or different anti infective drug schemes had the higher probability of medical insurance balance in the scenario where the medical insurance commissioner intervenes and the DRG enrollment was correct. Conclusions:The hospital adopted interventions from medical insurance specialists to ensure the correct DRG enrollment of patients, accurate use of parenteral nutrition and anti infective drugs, and reasonable control the cost of examinations and consumables, which could increase the probability of medical insurance balance for gastric cancer surgery patients. In the future, hospitals should further promote the procurement of drug consumables in bulk, reduce unnecessary examinations, develop standardized perioperative nutritional interventions and anti infection treatment pathways, ensure the accuracy of DRG enrollment, optimize clinical diagnosis and treatment pathways to improve the efficiency of medical insurance fund utilization and provide high-quality medical services for patients.

RESUMEN
Prosthesis for femoral head surface replacement was designed. Between January 2002 and December 2005,28 patients underwent femoral head surface replacement in Anyang People's Hospital. The diameter of the normal femoral head was determined by CT,and the prosthesis was selected according to the measured value ±1 mm. With the muscle gap approach,the center of the femoral head was determined according to the measured distance between the femoral head center and the culminated point of the round ligament fossa based on the mark of the culminated point of the round ligament pit. Additionally,the diameter of the femoral head was measured again to ensure the precise match of the prosthesis and acetabulum. X-ray films at 24-48 months show no loosening or dislocation of the prosthesis,which was well matched with acetabulum. Furthermore,the joint space did not remarkably change. The mean score was 63 before operation and 91.5 after operation respectively according to Harris sore. The successful rate is 92.86% (excellent in 23cases,good in 3,and improved in 2). The results show that femoral head surface replacement is an effective method for young patients with avascular necrosis of the femoral head at the stage of ARCO HI.
