Objective To explore the application of the evidence-based case report method in the standardization training of resident physicians in the department of endocrinology. Methods Fifty-one resi-dents recruited from the endocrinology department were randomly divided into the experiment group (26 cases) and control group (25 cases). The evidence-based case report method was conducted in the ex-peri-mental group, while the traditional clinical teaching mode was applied in the control group. The re-sults of the examination of two groups including the theoretical test and skill test were compared and the question-naire survey was conducted to find out the differences of students' interest in learning, clinical skills and satisfaction. All data were compared using t test. Results There was no significant difference in theoretical test between the two groups (P>0.05). The total score of the skill test in the experimental group was (85.13 ±4.63) and the control group was (76.79 ±3.11) (P=0.000). The students in the experimental group showed that the teaching method had more significant effects on improving their learning interest and initiative, clinical thinking ability, clinical work ability, literature review ability and medical article writing ability. Scores of satisfaction with teaching methods (total score was 10) for experimental group were (9.69 ±0.34), which was also significantly higher than those in the control group (8.01 ±0.39) (P=0.000). Conclusion The application of evidence-based case report teaching method in the standardized training of resident physicians in department of endocrinology is worthy of being perfected and further popularized in clinical teaching work.

Objective:To explore the clinical application of distal and proximal bilateral lateral pre-decompression in replant of digit degloving injury.Methods:From March 2012 to May 2021, 14 patients with 29 digits had replantation surgery of degloved soft tissue and severed digits in Section II, Department of Orthopaedics, Changzhou Medical District of 904th Hospital of PLA Joint Logistic Support Force. There were 2 types of injuries: degloving injury of soft tissue but with intact digital tip, and digital tip degloving injury with intact distal phalanx and nail bed. With the technique of distal and proximal bilateral lateral pre-decompression, pre-decompression incisions were made to the subdermal on both sides of the degloved skin over the proper palmar digital arteries. From where, the distal stump of the proper palmar digital arteries and nerves for anastomosis were found and had them anastomosed with the proximal proper palmar digital arteries and proper palmar digital nerves, then anastomosed digital pulp and digital dorsal veins (11 cases were direct anastomosis and 3 cases were bridged anastomosis). Follow-up was carried out by outpatient consultation, telephone and WeChat APP. The appearance of the digit body, the shape of digital pulp, the nails grow and the motions of the digits were observed, and the Evaluation Standard of Replantation of Severed Fingers by the Society of Hand surgery of Chinese Medical Association was used to evaluate the recovery of function.Results:All 29 segments of degloving digit survived. Small necrotic areas was found in 4 digits and healed after the change of dressing. The followed-up time was lasted for 3-36 months. There was no obvious atrophy found in all the digits. Appearances of digit pulp and nails were satisfactory with good sensational recovery for TPD at 6-10 mm, 7 mm in average. Motions of all the repaired digits were good. According to the Evaluation Standard of Replantation of Severed Fingers by the Society of Hand surgery of Chinese Medical Association, 23 digits were in excellent, 4 in good and 2 in poor, with a satisfactory rate at 93.1%.Conclusion:For a distal digit injury with intact distal soft tissue and relatively mild injury of blood vessels and nerves, using the method of distal and proximal bilateral lateral pre-decompression can help to achieve good appearance in survived digital pulp, good sensational recovery and good nail growth. An individualised treatment intra-and-after the surgery could offer an ideal therapeutic effect.

Background:
Insulin regulates glucose homeostasis and has important effects on metabolism, cell growth, and differentiation. Depending on the cell type and physiological context, insulin signal has specific pathways and biological outcomes in different tissues and cells. For studying the signal pathway of insulin on glycolipid metabolism in porcine embryonic fibroblast (PEF), we used high-throughput sequencing to monitor gene expression patterns regulated by insulin.
Objectives:
The goal of our research was to see how insulin affected glucose and lipid metabolism in PEFs.
Methods:
We cultured the PEFs with the addition of insulin and sampled them at 0, 48, and 72 h for RNA-Seq analysis in triplicate for each time point.
Results:
At 48 and 72 h, 801 and 1,176 genes were differentially expressed, respectively. Of these, 272 up-regulated genes and 264 down-regulated genes were common to both time points. Gene Ontology analysis was used to annotate the functions of the differentially expressed genes (DEGs), the biological processes related to lipid metabolism and cell cycle were dominant. And the DEGs were significantly enriched in interleukin-17 signaling pathway, phosphatidylinositol-3-kinase-protein kinase B signaling pathway, pyruvate metabolism, and others pathways related to lipid metabolism by Kyoto Encyclopedia of Genes and Genomes enrichment analysis.
Conclusions
These results elucidate the transcriptomic response to insulin in PEF. The genes and pathways involved in the transcriptome mechanisms provide useful information for further research into the complicated molecular processes of insulin in PEF.
