Chinese Health Economics 2017;36(4):36-39
The reform for medical insurance payment was the important method for standardizing medical service provider behavior,controlling costs and improving efficiency,which was also the important measurement for further improve and implement the reform of drug and health system.Since the new medical reform in 2009,the central and local government had paid more attention on the role of medical insurance payment reform.Local medical departments of different places implemented reform pilots.Through summarizing the foreign and domestic researches around capitation,bundle payment and global payment,the experiences and effectiveness of these pilots were evaluated so as to provide corresponding policy implications.

Objective To explore the syndrome distribution laws of refractory idiopathic thrombocytopenic purpura (RITP), and the relevance between various syndromes and gender, age, laboratory indicators, to reveal the essence of TCM syndrome and provide a reasonable and standard TCM treatment principle. Methods TCM syndrome, gender, age and laboratory indicators of 75 cases of RITP were studied retrospectively and analized statistically. Results Qi deficiency and blood stasis is the major syndrome, and Yin deficiency is the secondary syndrome. Compare with others, the patients with qi deficiency and blood stasis syndrome were older, and had longer disease courses and more severe conditions. Conclusion One of TCM intervention treatment principles for RITP is invigorating qi and yin, promoting blood circulation and removing blood stasis.

OBJECTIVE:To investigate the clinical characteristics and gene polymorphism of oxcarbazepine (OXC)- induced Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). METHODS:Retrieved from CNKI,Wanfang,VIP, PubMed,EMBase,SpringerLink and other databases,case reports about OXC-induced severe ADR were summarized and ana-lyzed. RESULTS:Twelve literatures were collected,and 13 case reports about OXC-induced SJS/TEN were obtained. Male had more OXC-induced severe skin ADR than female. ADR mostly occurred during 1-14 d after medication. All patients were cured with treatment of glucocorticoid and antiallergy,without death case. Genotyping for 8 patients were performed and 6 of them showed the presence of HLA-B*1502 allele. While HLA-B alleles of 2 patients were HLA-B*1518/B*4001,which was the variation of HLA-B*1502. CONCLUSIONS:OXC-induced ADR should be monitored closely. Great importance should be attached to patient education and follow-up program. HLA-B*1502 gene detection should be performed to guide rational use of OXC and optimize clini-cal drug use plan.

Objective To measure the levels of caspase-1 and its downstream factor interleukin (IL)-18 and IL-33 in rheumatoid arthritis (RA) and explore their possible mechanisms.Methods Blood samples were drown from 56 patients with RA and 22 healthy subjects.Serum levels of caspase-1,IL-18 and IL-33were tested by the method of enzyme linked immunosorbent assay (ELISA).Kruskal-Walls and Mann-Whitney test were used to compare the levels of caspase-1,[L-18 and IL-33 and Spearman's correlation test was used for correlation analysis.Results The level of caspase-1 was significantly increased in RA group compared to healthy group [(32±26) ng/ml vs (15±6) ng/ml,P<0.01].Meanwhile,the active disease groups showed a higher level than the remission group,and level in the untreated group was higher than the treated group [(47±27) ng/ml vs (25±22) ng/ml,P<0.01].The levels of IL-18 and IL-33 were significantly increased in RA group compared to healthy group [(121±121) ng/L vs (58±33) ng/L,(1032±1011) ng/L vs (510±231)ng/L,respectively,P<0.05].Meanwhile,the active disease groups had a higher level than the remission group and the untreated group had higher levels than the treated group [IL-18 and IL-33 were (172±139) ng/L vs (97±106) ng/L,(1469±1039) ng/L vs (825±941) ng/L,respectively,P<0.05].Caspase-1 was correlated withIL-18 and IL-33 (r=0.824,0.854,P<0.01) and IL-18 was correlated with IL-33 (r=0.800,P<0.01).But neither of the three factors was related with clinical indexes including disease duration,RF,anti-CCP antibody,tender joints count and swollen joints count.Conclusion Caspase-1 and its downstream factor IL-18,IL-33 increase in RA,and they may play important roles in RA.

Objective To construct eukaryotic expression plasmid pIRESneo3-pigment epithelium-derived factor (PEDF) and detect its transient expression in SP2/0 cells. Methods Specific primers were designed based on the mature peptide sequence of human PEDF cDNA in the GenBank. Human PEDF gene was cloned into the eukaryotic expression vector pIRESneo3. The PEDF DNA was transfected into SP2/0 with LipofectamineTM 2000. The recombinant human PEDF protein expressed in SP2/0 cell culture supernatant was identified by Western blot and enzyme-linked immunosorbent assay. The biological activity of the recombinant human PEDF was measured by 3-(4,5-dimethylthiazol-z-y1)-2,5-diphenytetrazolium bromide(MTT) method. Results PCR amplification, restriction enzyme digestion and DNA sequencing confirmed that the mature peptide sequence of human PEDF cDNA was successfully cloned into the eukaryotic expression vector pIRESneo3. And the plasmid was transfected into SP2/0 cells, which could secret PEDF. Western blot analysis showed that there was only one obvious band at the position of relative molecular weight of 50 000, and it is equivalent to the expected value. Enzyme-linked immunosorbent assay suggested that the content of PEDF began to rise after transfection, and peaked at 36 h [(0.92±0.04) μg/ml]. The proliferation of human umbilical vein endothelial cell line was significantly inhibited by supernatant after transfection of 36 h (P<0.05). Conclusions The eukaryotic expression plasmid pIRESneo3-PEDF had been successfully constructed and active human PEDF was transiently secreted, which made a foundation for further study of stable expression and purification of PEDF. This protein could be a potential medication for preventing and managing retinopathy of prematurity.

Objective To establish a method for the preparation of long-circulating liposomes (LCL) containing etoposide and to observe its stability in rats plasma.Methods The etoposide-containing liposome was prepared by ethanol injection method. Polyethylene glycol-distearoyl phosphatidylethanolamine (PEG2000-DSPE) was used to modify the membrane of the liposome. Reversed-phase high pressure liquid chromatography (RP-HPLC) was used to detect the concentration of the liposome,and dynamic release method was used to study its stability in mice plasma.Results The mean size of the LCL containing etoposide was (180?26) nm,and the mean concentration of etoposide was (4.78?0.22) mg/mL,with the entrapment efficiency being (88.71?8.2)%. The leakage ratio of the conventional liposome containing etoposide and LCL containing etoposide in mice plasma were (80.14?1.59)% and (46.72?2.61)%,respectively.Conclusion LCL containing etoposide with high entrapment efficiency and low leakage rate can be obtained by using ethanol injection method. Additionally,modification by PEG2000-DSPE could raise the stability of the liposome.

AIM: To provide experimental evidence for gene therapy of thrombophilia disease, we constructed the eukaryotic expression plasmid with human thrombomodulin (hTM) gene and observed the alteration of hTM expression on the surface of human umbilical vein endothelial cells (HUVECs) with and without the reconstructive plasmid. METHODS: The whole expressive fragment of hTM gene was amplified by PCR from human genome. Both hTM gene and pcDNA3.1(+)/neo empty vector was digested by HindⅢ and EcoRⅠ. Two digested fragments were ligated into pcDNA3.1/hTM with T_4DNA ligase. After identifying, the reconstructive plasmid transfected into HUVECs using lipofectin. The hTM antigen on the HUVECs was detected by immunohistochemistry. RESULTS: The hTM reconstructive plasmid was confirmed by double endonuclease redigesting and sequencing. About 10% HUVECs were transfected by pcDNA3.1/hTM plasmid with lipofectin and the high-level hTM was detected on the transfected cells. CONCLUSION: We constructed the pcDNA3.1/hTM plasmid successfully, and it could be expressed on the HUVECs. [
