The activity of interleukin-2(IL-2)and the expression of interleukin-2 receptors in the lymphocytes of peripheral blood were investigated in 15 cases of nasopharyngeal carcinoma and in normal subjects who served as control.It was found that the IL-2 activity and IL-2R expression were significantly lower in the patients than in the normal control.and they decreased continously when the patients were receiving radiotherapy.

Objective To assess the diagnostic value of Wells score and D-Dimer detection in acute pulmonary embolism. Methods Forty-two suspected cases of pulmonary embolism were collected from March 2012 to September 2014 Then Wells score and D-Dimer detection were applied to confirm the disease. Results Of the total, 26 patients were diagnosed by computed tomographic pulmonary arteriography (CTPA). There were 7, 24 and 11 suspected cases which had low, medium and high Wells score respectively. Among them, 1, 15, and 10 cases were diagnosed by CTPA. The diagnosis rates were 14.2% (1/7), 62.5% (15/24) and 90.9%(10/11) respectively. The D-Dimer level in pulmonary embolism group was significantly higher than that in non-embolism group(P < 0.01). The D-Dimer level of cases with medium or high Wells score was higher than those with low Wells score (P < 0.05). Conclusion Wells score combined with D-Dimer is convenient, accurate and safe for predicting acute pulmonary embolism.

The published English articles were mainly University of Toronto and University of Colorado. The main publishing institution of Chinese articles was the First Affiliated Hospital of Peking University. The United States and China took the lead in the number of core journals published in the field of hypertension in children, the United States ranked first in terms of the influence of publications. Keyword co occurrence analysis showed that the high frequency keywords in the English literature included prevalence, risk, obesity, risk factor, body mass index, insulin resistance, overweight, metabolic syndrome, cardiovascular disease and mortality. Chinese high frequency keywords in the literature include obesity, risk factors, adiposis, influencing factors, overweight, prevalence, diabetes, treatment, health education and body mass index. The analysis of keywords showed that 25 burst terms were obtained separately in English and Chinese literature. Conclusion In recent years, the research interest on hypertension in children continues to grow and keeps updated, with the research scope expanding significantly, regarding obesity, diabetes and cardiovascular diseases.

Objective:To investigate the clinical efficacy of fixed-bearing unicompartmental knee arthroplasty (UKA) in the treatment of anteromedial knee osteoarthritis or spontaneous osteonecrosis of the femoral condyle.Methods:Between June 2017 and June 2018, 62 consecutive patients were treated at Department of Joint Surgery, Fuzhou Second Hospital Affiliated to Xiamen University for anteromedial knee osteoarthritis or spontaneous osteonecrosis of the femoral condyle using a fixed-bearing UKA system. They were 27 men and 35 women, aged from 58 to 85 years (average, 69.8 years). There were 58 cases of anteromedial knee osteoarthritis and 4 cases of spontaneous osteonecrosis of the femoral condyle. The courses of disease ranged from 2 to 10 years (average, 5.1 years). Medial unicompartmental knee arthroplasty was performed for all the patients on the fixation platform SLED. Recorded were the hip-knee-ankle angle (HKA) of the patients 2 days after operation, Oxford knee score (OKS) and American Knee Society score (KSS) at the final follow-up and post-operative complications.Results:The 62 patients were followed up for 9 to 21 months (average, 15.6 months). Tibial plateau fracture occurred in one case who eventually obtained bony union after open reduction and internal fixation. Another case had a wound healing problem which responded to drainage and debridement with prosthesis preservation. Another case presented prepatellar pain which was improved after physical therapy. In the 62 patients, the HKA 2 days after operation (172.27°±1.61°) was significantly improved compared to the preoperative value (177.79°±1.32°), the OKS at the final follow-up (19.8±2.7) significantly lower than the preoperative value (50.2±3.1), and the KSS at the final follow-up (89.7±2.6) significantly higher than the preoperative value (49.6±5.2) (all P<0.05). Follow-ups revealed no cases of joint infection or prosthetic loosening. Conclusion:Fixed-bearing unicompartmental knee arthroplasty can lead to fine short-term outcomes for anteromedial knee osteoarthritis or spontaneous osteonecrosis of the femoral condyle.

Objective:To verify the application value of team-based learning (TBL) joint case-based discussion (CBD) method applied in the course teaching of Introduction to General Practice.Methods:Students from two clinical oriented classes in the same grade were divided into the experimental group ( n=35) and the control group ( n=35). The control group implemented the traditional teaching method, and the experimental group implemented the TBL joint CBD method. The teaching effect were compared between the two groups. SPSS 20.0 was used for frequency description and statistical test analysis. Non-normal distribution data were tested with Mann-Whitney U test. Results:After the teaching, the average rank of multiple-choice questions (35.28) and analytic questions (42.24) in the experimental group were significantly higher than those of the control group (32.68 and 25.52, respectively, P<0.05). Conclusion:The TBL joint CBD method applied in the course of general practice helps to improve students' test achievement, enhance their overall quality, and lay a foundation for training comprehensive competencies of general practitioners.

OBJECTIVES: This study examined the associations between adverse childhood experiences (ACEs) and diabetes within a social-ecological framework, incorporating personal and environmental unfavorable conditions during childhood from family, school, and community contexts. METHODS: Data were obtained from the China Health and Retirement Longitudinal Study (2014 life history survey and 2015 survey), including 9,179 participants aged ≥45 years. ACEs were collected through self-report questionnaires, and participants were categorized based on the number of distinct ACEs experienced (0, 1, 2, 3, or ≥4 ACEs). Diabetes was defined by biomarkers, self-reported diagnosis, and treatment status. Logistic regression was conducted to explore the associations between ACEs and diabetes. Subgroup analyses were conducted by gender, age, and obesity status. RESULTS: Compared with participants without ACEs, those exposed to any ACE (odds ratio [OR], 1.19; 95% confidence interval [CI], 1.01 to 1.40), 3 ACEs (OR, 1.32; 95% CI, 1.07 to 1.62) and ≥4 ACEs (OR, 1.29; 95% CI, 1.07 to 1.56) had an increased risk of diabetes. For each additional ACE, the risk of diabetes increased by about 5%. Regarding the source of ACEs, those originating from the family (OR, 1.23; 95% CI, 1.08 to 1.41) were associated with diabetes. In terms of specific ACE types, family members with substance abuse (OR, 1.23; 95% CI, 1.01 to 1.52), emotional abuse (OR, 1.28; 95% CI, 1.12 to 1.46), and poor parental relationship (OR, 1.25; 95% CI, 1.09 to 1.43) were associated with diabetes. CONCLUSIONS ACEs, particularly those originating from the family, were associated with diabetes. Interventions aimed at preventing and mitigating ACEs are essential for the early prevention of diabetes.
