Based on the background,conception and the core ideas of the evidence-based medicine,the construction and application of domestic clinical cases database was discussed.Problems concerning statistics,management and application in scientific research encountered in the database devel opment were presented,and suggestions were proposed.

Objective To investigate the prevalence of chronic kidney disease (CKD)and risk factors in the adult population of Tianshan district in Urumqi, Xinjiang. Methods A total of 2131 residents from 4 communities in Tianshan district of Urumqi city were randomly selected using a stratified, multistage sampling. All the residents were interviewed and tested for morning spot urine of albumin to creatinine ratio (ACR) (abnormal ≥ 30 mg/g), morning spot urine dipstick of hematuria ( abnormal ＞3 red blood cells/HP or greater) and pyuria ( abnormal＞ 5 white blood cells/HP) confirmed by microscopy. Renal function was determined with abbreviated MDRD equation [reduced estimated glomerular filtration rate (eGFR)＜60 ml ·min-1 ·(1.73 m2)-1]. The associations of kidney damage indicators with age, gender, hypertension, diabetes mellitus, income,education, cholesterol, triglyceride and smoking were examined. Results Eligible data of 2131 subjects were collected in the study. After the adjustment of age and gender component, the prevalence of albuminuria was found in 2.63％ (95％CI:1.78％-3.48％) of subjects, hematuria in 7.43％(95％CI:6.11％-8.75％) and reduced renal function in 1.72％(95％CI:1.08％-2.35％).Approximately 9.99％(95％CI:8.47％-11.55％) of subjects had at least one indicator of kidney damage. Multivariate logistic regression revealed that albuminuria, hematuria, age and hyperuricemia were independently associated with reduced renal function. Hematuria and reduced renal function were independently associated with albuminuria. Albuminuria, reduced renal function and female were independently associated with hematuria. Conclusion In urban adult population over 35 years old of Urumqi, a big city in western China, the prevalence of CKD is 9.99％, the recognition is 2.44％ and the risk factors of CKD are similar to those of other domestic big cities and western developed countries.

Objective:To understand the current state of financial toxicity and suicide risk in head and neck cancer patients, to investigate the correlation between the level of financial toxicity and suicide risk in head and neck cancer patients, and to provide a basis for reducing the level of financial toxicity and the risk of suicide in head and neck cancer patients.Methods:A cross-sectional survey was conducted, from March 1 to July 31, 2022, 150 head and neck cancer patients were selected from Oncology Department of East Hospital Affiliated to Tongji Universityby by convenient sampling method. The survey was carried out by means of the general questionnaire, Comprehensive Score for Financial Toxicity based on the Patient-Reported Outcome Measures (COST-PROM), Cancer Suicide Risk Scale (CSRS), and then analysis the datum.Results:The score of COST-PROM of 150 head and neck cancer patients was (18.00 ± 6.12) points, and the score of CSRS of head and neck cancer patients was (36.31 ± 8.51) points. The total score of economic toxicity was significantly negatively correlated with the total score of suicide risk and its dimensions ( r values were -0.446 to 0.235, all P<0.05). The total score of suicide risk was negatively correlated with the total score of economic toxicity and the scores of each dimension ( r values were -0.446 to -0.251, all P<0.05). Conclusions:Patients with head and neck cancer were at higher risk of suicide, and financial toxicity was a significant contributing factor to suicide risk, with higher levels of financial toxicity associated with a higher risk of suicide. Reducing the level of financial toxicity in patients with head and neck cancer has important implications for reducing their risk of suicide.

Neonatal hypoglycemia，a common disorder of abnormal glucose metabolism，occurs especially in preterm newborns.Hypoglycemia that occurs frequently and persistently may result in severe consequences for premature infants，including death or permanent brain damage.In recent years，an increasing number of research findings have demonstrated that the following conditions have been linked to an increased risk of hypoglycemia in preterm infants：maternal sickness during pregnancy，pharmaceutical use during pregnancy，and various pathophysiological states of the preterm infant.This review summarizes the current pathophysiological mechanism，risk factors，diagnosis，prevention，and treatment of hypoglycemia in preterm newborns through analyzing the pertinent literature that has been published recently both domestically and internationally，with the aim of early detection，early diagnosis and early treatment，and reducing the incidence of hypoglycemia.

Objective:To construct the risk control operation and maintenance management system of TiRobot Recon navigation system of Tianji orthopedic robot(hereinafter referred to as the risk control operation and maintenance management system)and to analyze the application effect,so as to provide theoretical guidance and reference for improving the clinical service effect and quality of Tianji orthopedic robot.Methods:By reviewing the literature and summarizing clinical practice experience,the risk critical control points of the TiRobot Recon navigation system were clarified,and the risk control operation and maintenance management system was constructed based on this.The management effect of TiRobot Recon navigation system before the implementation of system(January 2022 to December 2022)and after the implementation(January 2023 to December 2023)was compared.Results:After the implementation of the risk control operation and maintenance system,the average daily use time,expected target compliance rate,system risk event reporting accuracy,risk early warning timeliness and risk event data standardization of TiRobot Recon navigation system were higher than before the implementation,and the system failure standby time and failure rate were lower than those before the implementation,and the difference was statistically significant(t=6.956,9.656,5.415,4.678,3.711,3.354,5.229,P<0.05).After the implementation of the risk control operation and maintenance system of sub-line control,the scores of daily maintenance,pre-use inspection,post-use cleaning,system operation,fault response,emergency treatment and other operation proficiency scores of the TiRobot Recon navigation system were higher than those before the implementation,and the difference was statistically significant(t=4.225,2.399,2.385,2.597,2.421,3.560,P<0.05).Conclusion:The use of risk control operation and maintenance platform can improve the use effect of TiRobot Recon navigation system,strengthen the operation proficiency of personnel,with obvious advantages in clinical application and promotion value.
