Objective To observe the difference of caveolin-3(CAV3) gene polymorphism between normal people and diabetic patients in Chinese Han population. Methods Exon gene polymorphism in 50 normal people and 50 T2DM patients were detected by PCR-SSCP. Results The cumulative incidence rate of electrophoretic variation in T2DM patients was 48%, while cumulative incidence rate of normal people was 7%(P<0.001). It was proved that in the variant bands, there were base variant. Conclusions The variant base number of CAV3 gene in human T2DM samples are significantly more than the normal which can be preliminary detected by PCR-SSCP. It indicates that CAV3 gene polymorphism may be one of the genetic backgrounds for the occurence of Chinese T2DM.

Objective: To explore the efficiency of simple scoring model based on multi-slice spiral CT (MSCT) for differential diagnosis of focal esophageal carcinoma and esophageal leiomyoma. Methods: Totally 46 patients with focal esophageal carcinoma and 21 with esophageal leiomyoma who underwent preoperative chest enhanced CT were retrospectively analyzed. The lesion's location, density, size (the thickest wall on axial position and the longest diameter on multi-planar reconstruction [MPR]), the ratio of the longest diameter on MPR to the thickest wall on axial position, enhancement degree, tumor-air surface, peritumoral fat space and enlarged lymph nodes were assessed, and Logistic regression analysis was used to select MSCT signs significantly different between two diseases to establish a simple scoring model. Receiver operating characteristic curve (ROC) was used to evaluate the diagnostic efficiency of this model. Results: The ratio of the longest diameter on MPR to the thickest wall on axial position (odds ratio [OR]=0.154, 95%CI [0.033, 0.722]), enhanced CT value (OR=0.928, 95%CI [0.866, 0.994]), tumor-air surface (OR=0.028, 95%CI [0.004, 0.184]) were significantly different between focal esophageal carcinoma and esophageal leiomyoma(P<0.05), and a simple scoring model then was established. The enhanced CT value of tumor >65.5 HU was defined as 1 point, the ratio of the longest diameter of MPR to the thickest wall on axial position >1.61 as 2 points, and the unsmooth tumor-air surface as 4 points. Taken 2.5 points as the cutoff value for diagnosing esophageal carcinoma, the area under curve (AUC) of this model was 0.945 (95%CI [0.891, 0.999]), better than that according to single features (P<0.05). Conclusion: The simple scoring model based on MSCT was helpful to differentiation of focal esophageal carcinoma from esophageal leiomyoma and improving diagnostic efficiency.

Objective To study the effect of social isolation( SI) on the exploratory behavior and working memory in mice. Methods The Kunming mice of postnatal 21 days were divided into the control group,SI 2 weeks group,SI 2 weeks gregarious group,SI 4 weeks group and SI 8 weeks group,according to randomized design with ten animals each. All isolated mice were isolated for 2, 4 and 8 weeks respectively, the gregarious group were housed under normal grouped housing enviroment after isolation until adult, the mice with the relative same age were control groups. All animals were measured for exploratory behavior and working memory by performing open field and T?maze after the treatment. Results In the open field,compared to the relative control group,the central area of the total time in the SI 4 weeks group(0.07±0.04) was less than the control (0.10±0.04) obviously. The central area percentage of total time in SI 8 weeks group (0.64±0.12) were more than the control (0.43±0.08). In the T?maze,the alteration times in SI 2 weeks group (first day (5.92±0.79),second day (6.67±1.3),third day (7.42±1.08),fourth day (8.17±1.27)) were less than the control (first day (6.80±1.14); second day (7.60± 0.84);third day (8.30±0.95);forth day (9.20±1.32)). However,the alteration times of gregarious group showed no obvious change. Both the alteration times of SI 4 weeks (8.18±1.99) in the second day and that of SI 8 weeks (8.29±3.04) in the forth day were more than the control (6.60±2.11) and (7.80±2.53) respectively.Conclu?sions Working memory of SI 2 weeks rats decrease,which can be improved by the resocialization.SI 4 weeks and 8 weeks rats show the decreasing exploring ability and increasing anxiety and work memory.

Objective It aims to analyze the resource distribution of Chinese gradeA teritary hospitals across six regions from 2012 to 2021,so as to further understand the changes in inter-regional health resource allocation.Methods Based on the"Thirteenth Five-Year Plan"for the Establishment of National Medical Centers and Regional Medical Centers,it utilizes indicators such as the annual growth rate,coefficient of variation,agglomeration degree,and Theil index to explore the resource allocation in Chinese gradeA teritary hospitals from 2012 to 2021.Comparative and trend analyses are also conducted.Results The regional difference of high-quality medical resources in the country has continued to narrow,especially with an increased rate of reduction since 2017.The Theil index of resource allocation in grade A teritary hospitals in various regions of the country has decreased from 0.035 0 to 0.020 5,indicating a positive trend towards fairness and a gradual increase in regional development coordination.An imbalance in the geographical distribution of resources among third-class medical institutions persists across various regions of China.Conclusion The resource allocation of grade A teritary hospitals in the western region should fully consider geographical factors and change the traditional single"human-oriented"resource allocation mode.Grade A teritary hospitals in economically developed areas still need to increase resource investment,conduct proactive population monitoring,early warning,and macro resource planning.The resource allocation of third-class medical institutions should focus on both intra-regional development and inter-regional collaboration to enhance the quality and efficiency of resource distribution.
