After the important role of interoperability in health information construction , organizational interopera-bility and inter-organizational network studies were analyzed , the analyzing framework for inter-organizational net-work of medical and health organizations and its relevant study directions were proposed from the aspects of its nodes, dyads and overall structure.

Objective To study the electroacupuncture effects of the single point Zusanli or Sanyinjiao on simple obese rats and to observe the regulation of fat metabolism.M[ethods Before and after the treatment,the body weights and lengths of rats in each group were measured tO calculate the Lee's index;besides,total cholesteriol (TC) and triglycerides (TG) in the rat blood were also determined.Finally,the rats were treated and observed for tWO courses,and SPSS11.5 statistical software was employed to conduct statistical analysis of the experimental data.Results A significant difference was observed about the effects on the height,weight,Lee's index,TC and TG between treatment group and the model group or normal control group (P<0.05 or P<0.01),but no significant difference between treatment group and normal control group (P>0.05).Conclusion Electroacupuncture of Zusanli and Sanyinjiao points has effects on simple-obesity rats,which can make weight loss and decrease Lee's index,TC and TG levels.The underlying mechanism may relate to the improvements of fat metabolism.

BACKGROUND:MicroRNA(miRNA)levels are closely related to cell apoptosis and proliferation,extracellular matrix metabolism and inflammatory response in intervertebral disc cells.However,the specific role of miR-142-3p in lumbar intervertebral disc degeneration remains unclear. OBJECTIVE:To investigate the correlation between the expression of miRNA-142-3p,mixed lineage kinase 3 and interleukin-1β in nucleus pulposus tissue and degree of human lumbar intervertebral disc degeneration. METHODS:A total of 82 patients with lumbar intervertebral disc degenerative diseases in Suzhou Ninth People's Hospital from January 2020 to March 2022 were collected as the study subjects,all of whom underwent MRI examination before operation.According to the Videman classification,the patients were divided into mild degeneration group(n=36),moderate degeneration group(n=26)and severe degeneration group(n=20).Eighty-two specimens of the nucleus pulposus were obtained.The mRNA expression of miRNA-142-3p as well as the mRNA and protein expression of mixed lineage kinase 3,interleukin-1β,type I collagen,type II collagen in nucleus pulposus tissue were detected by qPCR and western blot assay.The correlation between the degree of human lumbar intervertebral disc degeneration and the expression levels of miRNA-142-3p,mixed lineage kinase 3,and interleukin-1β was also assessed using the Spearman correlation coefficient method.Thirty adult Sprague-Dawley rats were divided into sham-operated group(executed after puncturing skin and muscle only),mild degeneration group(executed 1 week after puncturing Co7/8 segments)and severe degeneration group(executed 2 weeks after puncturing Co7/8 segments),with 10 rats in each group.After that,we detected the protein expression of mixed lineage kinase 3 and interleukin-1β as well as the gene expression of miRNA-142-3p,mixed lineage kinase 3 and interleukin-1β in the nucleus pulposus tissue. RESULTS AND CONCLUSION:In human nucleus pulposus tissue,the miRNA-142-3p expression ranked from high to low as follows:mild degeneration group>moderate degeneration group>severe degeneration group(P<0.05);the gene and protein expression of mixed lineage kinase 3 and interleukin-1β from low to high was as follows:mild degeneration group
