新冠肺炎疫情防控期间医院防护物资管理实践探讨

新冠肺炎传染性强、扩散速度快，防护物资消耗量和需求量骤增，全国各级医院都面临医用防护物资紧缺问题。针对防护物资紧缺现状，通过建立组织架构，明确岗位防护标准，严格防护物资管理，完善物资请领审批流程等举措，对防护物资进行科学管控、合理调配，保证了诊疗工作正常开展，保障了医务人员安全     

Rapid and Robust Transgenic High-Grade Glioma Mouse Models for Therapy-Intervention Studies

PURPOSE:To develop a transgenic mouse model of glioma that can be conveniently used for testing therapy-intervention strategies.High-grade glioma is a devastating and uniformly fatal disease for which better therapy is urgently needed.     

The effect of gastrografin and glucagon on CT scanning of the pancreas: a blind clinical trial

The effect of Gastrografin and glucagon on pancreatic CT scanning was studied in a blind clinical trial. Twenty-five patients had a pancreatic CT scan performed on an 18-second scanner and a repeat pancreatic CT scan following administration of Gastrografin and glucagon. The results were statistically significant: decreased streak artifacts; improved pancreatic head, body and tail delineation; and improved overall pancreatic visualization. Gastrografin-glucagon administration is recommended prior to pancreatic CT scanning if the scanning cycle is 18 seconds or longer.     

Self-fixing parietex progrip versus the standard sutured prolene mesh in tension-free repair of inguinal hernia: effect on testicular volume and testicular blood flow

Our study was conducted to compare self-fixing lightweight polyester mesh (group I) to the standard heavy weight polypropylene mesh (group II) using tension-free Lichtenstein hernioplasty as regard to the effect of mesh implantation and perimesh fibrosis on testicular blood flow. 80 patients with uncomplicated inguinal hernia were divided in two groups. Doppler ultrasonography measured testicular volume, testicular artery velocity preoperative and 3rd month post operative. Blood flow in the testicles was represented by resistive index (RI). No case of testicular atrophy occurred in either group, however, in both groups a significant postoperative decrease in testicular volume (p?=?0.001 in group I and p?<?0.001 in group II) was accompanied by a significant increase in RI as compared to their pre-operative values (p?<?0.001 in group I and p?=?0.009 in group II). Comparing the two groups, patients in group I showed higher values of decrease in testicular volume accompanied by more increase in RI values postoperatively compared to group II patients, but these values did not reach a significant value (p?=?0.107, p?=?0.136). There was a significant increase in the number of post-operative varicocele and hydrocele in group I compared to group II. Mesh implantation has an effect on testicular size and blood flow by decreasing the testicular size and increasing the RI. This effect was more obvious in the parietex progrip. Although there is an indirect relation between RI and the sperm count, testicular blood flow alone is not enough to judge fertility.
