Objective To discuss the serum levels of the Adipokine Chemerin、RBP4 of Gestational Diabetes Mellitus(GDM) in early pregnancy and middle pregnancy. Methods In prospective study, pregnant women, venous blood was collected from 40 controls and 38 GDM during early pregnancy (9-12weeks)and middle pregnancy (22-26weeks). Serum insulin, Chemerin, RBP4 were measured by enzyme-linked immunosorbent assay (ELISA). Results Mean serum levelsof Chemerin and RBP4 were significantly higher among GDM cases compared with controls during early pregnancy and middle pregnancy(P<0.05). In two groups, Mean serum levels of Chemerin and RBP4 in middle pregnancy were significantly higher than those in early pregnancy (P<0.05).During early pregnancy and middle pregnancy, the Chemerin and RBP4 levels were positively related with HOMA-IR (P＜0.05). Conclusion There is evidence of a positive association elevated Chemerin and RBP4 concentration of early pregnancy and middle pregnancy with increased GDM risk.

目的 探讨纵隔髓外造血(EMH)的临床特点,从而为其诊断、治疗提供参考意见。方法 总结分析我科收治的1例双侧后纵隔骨髓外造血组织多发瘤样增生,并对近10年来国内相关文献报道的27例病例进行回顾性分析。结果 患者需行手术活检取得病理诊断,确诊髓外造血。结论 纵隔髓外造血瘤样增生是一种罕见特殊的良性病变, 预后良好。但因其临床表现和影像学均缺乏特异性,当临床中遇到发生在后纵隔脊柱旁的占位性病变,同时患有贫血的患者应考虑EMH 的可能性,给予经皮穿刺或者胸腔镜下活检来取得细胞学诊断,从而避免不必要的手术治疗。

Objective To probe into the clinical features of mediastinal extramedullary hematopoiesis (EMH), for providing a reference for clinical diagnosis and treatment. Methods The clinical data was studied in a case of mediastinal EMH from our department, and 27 case reports from domestic published literatures over the last decade were analyzed retrospectively. Results Of the 27 patients, 15 received surgical excision, while the other 12 underwent needle biopsy. In our patient, the diagnosis of EMH was made by mini thoracotomy and open biopsy. Conclusion Mediastinal EMH is a rare disease and its prognosis is well. Because there is no obvious specific clinical symptoms and imaging appearances, the possibility of EMH should be considered when a patient with a mediastinal tumor associated with anemia is encountered. Diagnosis can be achieved by needle biopsy or video-assisted thoracic surgery (VATS) in order to prevent unnecessary surgical procedures.

目的 建立胎儿左、右肺面积及肺头比的正常参考值范围。方法 对501例正常单胎妊娠12～40周胎儿在标准四腔心切面应用手工描绘法分别描迹左肺、右肺面积,分别除以头围获得左、右肺头比。结果 获得正常妊娠胎儿左、右肺面积及肺头比各孕周参考值范围。胎儿左、右肺面积及肺头比均随孕周的增长而增大。结论 正常妊娠胎儿左、右肺面积及肺头比与孕周呈正相关。不同孕周LHR参考值的建立有利于临床评价膈疝及其他胸腔占位性疾病的预后。

Objective To establish reference intervals for fetal left and right lung areas and lung area to head circumference ratio (LHR). Methods In 501 cases of normal singleton pregnancy between 12 to 40 weeks, the left and right lung areas were measured respectively by ultrasound in the standard four chamber view, using manual tracing of the limits of the lungs. The left and right LHR were calculated when head circumferences were divided by the left and right lung area. Results Normal fetal reference intervals of left and right lung areas and LHR with gestational age were obtained. Fetal left and right lung areas and LHR increased with gestational age. Conclusion Fetal left and right lung areas and LHR values positively correlated with gestational age in normal pregnancy. Normal reference intervals of fetal LHR for every gestational age are valuable for evaluation of prognosis of fetal diaphragmatic hernia and other pulmonary peripheral space-occupying lesions.

Objective The mechanism about biofeedback is not complete clear. Our aim was to study changes of cardiac function (electrophysiology) during biofeedback with the help of approximate entropy (ApEn), and a potential new mechanism about neurofeedback may be detected. Methods A total of 30 healthy volunteers participated in this study which consisted of the neurofeedback group(n=20) and the control group (n=10). We applied electromyogram neurofeedback as the feedback method, and simultaneously recorded electroencephalogram(EEG) and electrocardiogram(ECG). We applied the nonlinear analysis ApEn assess obtained data. Results In the biofeedback group the average of heart rate was higher than that of control group in the last two sessions. As the biofeedback experiment sessions were progressed, the standard deviation of heart rate gradually reduced and the ApEn of ECG increased with statistic significance in the biofeedback group. Conclusion We found that biofeedback can influence cardiac electrophysiological system and make cardiac systems progress healthily and achieve greater ability of anti-stress.

Methods This study entailed the compilation of 4 328 patient files from individuals who received surgical treatment for inguinal hernia at a third-level general hospital over the period spanning 2016 to 2022. Preliminary analysis was conducted on isolated variables, followed by the development of a model using AMOS 28. 0 for fit assessment. Results The fitting of structural equation model reached the standard. The total effect values of gender, age, cost, number of hospitalizations, admission route, concomitant disease, unilateral and bilateral hernia on the total cost were 0. 008, -0. 044, 0. 062, 0. 014, -0. 119, 0. 106, 0. 236, respectively. Gender, age, cost, number of hospitalizations, admission route, concomitant disease, unilateral and bilateral hernia indirectly affected hospitalization expenses through hospitalization days. Conclusions Gender, age, cost, number of hospitalizations, of admission, concomitant diseases, unilateral and bilateral hernia, and length of hospital stay have an impact on hospitalization costs. It is suggested to implement the pre-hospitalization mode and day surgery, complete relevant examinations before formal hospitalization, and optimize the medical service process, so as to reasonably and effectively control the hospitalization cost of single disease.

Among the single intervention individuals, the re-visit rate was 84. 34%（210/249）, and after the comprehensive implementation of measures, the re-visit rate among the successfully intervened individuals was 94. 74%（216/228）. After the intervention,the problem solving ability,responsibility, communication and coordination,team cohesion, enthusiasm,quality control techniques,self-confidence,and sense of harmony all significantly increased（P<0. 05）. The patient satisfaction rate before intervention was 85. 37%, and after intervention it was 87. 80%. The satisfaction rate increased after intervention, and the difference was statistically significant（P<0. 05）. Conclusions Through the quality control circle activities, the telephone follow-up rate of important abnormal results is significantly improved,which is conducive to improving the service quality and service capacity of physical examination institutions,is conducive to the early detection and early intervention of diseases.

       目的   通过对广东省下的卫生资源配置的公平性进行分析，找出当前卫生资源配置存在的问题并提出优化建议，以进一步减少健康不平等的现象，为实现广东省均衡化配置卫生资源的“十四五”目标提供实践参考依据。方法  收集整理《广东省统计年鉴》中2018—2022年相关数据，采用集聚度法、空间自相关分析，从人口、地理、空间三个纬度对卫生资源分布的公平性进行分析。结果  珠三角、粤东地区的卫生资源配置公平性，在地理维度上较高，人口维度上较低；粤西、粤北地区的卫生资源配置的公平性与之相反。在空间分布上，2018年部分城市的卫生资源分布呈现出一定的空间集聚特征，但到2022年这种空间集聚特征均弱化，空间自相关性消失。结论  广东省卫生资源在地域之间存在分布不均衡情况，其配置公平性有待提升。尽管空间自相关消失可能意味着资源不再集中在某些特定区域，但政策制定者在未来进行卫生资源规划时，要考虑如人口密度、经济发展水平等因素给各地区带来的影响，以进一步促进资源的均等化配置。
