Objective To investigate the effects of high density lipoprotein (HDL) on thrombin-activated platelet al-pha-granulemembrane protein (CD62P) and lysosome intact membrane protein (CD63) expressions in vitro. Methods The equivalent volume of washed platelets prepared by hand was preincubated with HDL (1 g/L) in 37℃water for 15 minutes, which was then stimulated with different concentrations of thrombin (0.5 U/mL, 1 U/mL and 10 U/mL) for 10 minutes in wa-ter of 37℃. Meanwhile another three groups of washed platelets were incubated with thrombin (0.5 U/mL, 1 U/mL and 10 U/mL) for 10 minutes, respectively. The CD62P and CD63 from each sample were analyzed by flow cytometry (FCM). Results The CD62P positive rates of HDL-preincubated groups were significantly lower than those of different concentrations of thrombin groups (0.5 U/mL,1 U/mL and 10 U/mL) in the absence of HDL (11.55%± 1.34% vs 18.14%± 1.50%, 17.19%± 0.17% vs 26.24%± 0.77% and 19.79%± 0.32% vs 80.38%± 5.66%,P ＜ 0.01). Meanwhile, The CD63 positive rates of HDL-preincubated groups were also significantly lower than those of thrombin-treated (0.5 U/mL, 1 U/mL and 10 U/mL) groups without HDL, namely,2.92%±0.22%vs 8.09%±0.48%(P＜0.001), 4.20%±0.98%vs 14.15%±1.39%(P＜0.001) and 5.12%± 0.09% vs 24.48%± 1.71%(P ＜ 0.01). Conclusion HDL inhibits the expression of CD62P and CD63 on throm-bin-stimulated platelets in vitro.

Objective To prokaryotically express the valosin-containing protein(VCP)of Schistosoma japonicum,and ana-lyze its VCP mRNA expressions in the cercaria,schistosomulum,adult worm(female and male worms)and egg. Methods RNA of S. japonicum eggs were extracted,and reversely transcribed into cDNA. The VCP gene of S. japonicum was amplified by using polymerase chain reaction(PCR),and subcloned into the prokaryotically expressed vector pET15b. The recombined plasmid was transformed into BL21 cells,and the expression of the target gene was induced with isopropyl-beta-D-thiogalactopyranoside (IPTG). The recombinant protein was yielded through the purification of inclusion body,and identified by using sodium dodecyl sulfate polyacrylamide gel electrophoresis(SDS-PAGE). The RNA(s)of cercaria,schistosomulum,female adult worm,male adult worm,and egg of S. japonicum were extracted,digested with DNase,purified,and reversely transcribed into cDNA. The mRNA expressions of the VCP gene in various developmental stages of S. japonicum were determined by using fluorescence-based quantitative real-time PCR. Results The VCP gene of S. japonicum was yielded by PCR amplification,and the recombinant pro-tein was obtained through recombinant plasmid expression and purification of inclusion body. The highest VCP mRNA expression in S. japonicum cercaria was detected by the fluorescence-based quantitative real-time PCR,while low expressions were found in the schistosomulum,egg,female and male adult worms. Conclusion The recombinant protein encoded by the VCP gene of S. ja-ponicum is successfully obtained,and the VCP mRNA expression is determined in various developmental stages of S. japonicum.

Medical insurance fund is the foundation for the healthy operation of the medical insurance system, which is related to the well-being of the people and social stability. Medical institutions, as important entities in the implementation of medical insurance policies and the use of medical insurance funds, should continuously improve and optimize their self-management, and strengthen the prevention and control of clean risks in the use of medical insurance funds. This is not only a necessary response measure in the context of strict supervision of national medical insurance funds, but also an inevitable choice for hospitals under the trend of high-quality development. This article took a certain hospital as an example to illustrate the practice of sorting out the relevant authority directory for the use of medical insurance funds, analyze the integrity risk points of doctors, patients, and medical insurance reimbursement auditors; And introduced the practice of using a clean risk prevention and control grid to strengthen the hospital′s medical insurance fund, including improving the medical insurance management system, cultivating a sustainable culture of integrity, optimizing process design, improving information system construction, and improving medical insurance service modes, so as to provide reference for other medical institutions.
