A nice biomaterial,which could replace the correlated tissue or organic of human body,supports the homologous function of organism,and accelerates the process of self recovery and autotherapy in the same time.The application of biomaterial in clinic,not only have the chemical characters and function of vitodynamics to match,but also be with nice biocompatibility and practical safety.Some development of biomaterial and the biocompatibility of it in this paper was reviewed,and the application status in the cardiothoracic surgery in recent years.

With the development of the cross-correlation technique in surgery, the transplantation and vi-cariousness have become more and more important in repair surgery and reconstructive surgery. A nice bio-material could replace the related tissue or organ of human body, support the homologous function of organ-ism,and accelerate the process of self recovery and autotherapy. This review is about the status of research and application of biomaterial in surgery.

Objective To investigate the variation of the oxidative stress status in type 2 diabetes mellitus(T2DM)patients with acute coronary syndrome (ACS)and significance.Methods Eighty -nine patients hospitalized in our department from September 2012 to April 2014 were divided into three groups: T2DM control (group DM), T2DM with coronary artery disease(group DM-CAD) and T2DM with acute coronary syndrome (group DM-ACS).Blood glucose,HbA1C,Lipids,serum Malondialdehyde (MDA) level, su-peroxide dismutase(SOD) activity, glutathione peroxidase (GSH-Px) activity and total anti-oxidation capacity(T-AOC) were deter-mined.Results Blood glucose、HbA1C and Lipids were similar in three groups ( P >0.05).Compared to group DM and group DM-CAD, serum MDA levels in group DM-ACS were significantly higher( P <0.05), while SOD、GSH-Px activities and T-AOC were sig-nificantly lower than those in group DM and group DM -CAD( P <0.05).Conclusions The oxidative stress level being significantly increased in T2DM patients with ACS.

Objective To explore clinic manifestations and laboratory investgation of virus encephalopathy.Methods The clinical course,cerebrospinal fluid(CSF),hepatic dysfunction,computerized tomography of 7 cases treated in our hospital from October 1999 to March 2005 were retrospectively reviewed.Results Seven cases of virus encephalopathy were typically associated with a suddent onset of high fever,severe convulsion,rapidly progressive coma,marked elevations of alanine aminotransferase(AST) and aspartate transaminase(ALT).Four cases died,3 cases had severe sequelae.Blood ammonemia was normal,brain CT scans revealed peripheral or basal nuclei low-density areas.Conclusion Children with a sudden onset of high fever,severe convulsions,rapidly progressive coma may have a poor prognosis.

BACKGROUND:At present, the confrontation of CAD/CAM systems and the lost wax casting method for marginal adaptation has been widely concerned, but the results are controversial. OBJECTIVE:To compare the marginal adaptation of single cobalt-chromium PFM crowns produced by 3 Shape CAD/CAM systems and the lost wax casting method. METHODS: A maxilary first premolar was prepared according to the standards. 50 resin-generation models were created by bi-color silicone rubber method and randomly divided into two groups: CAD/CAM group (A1-A25) and cast group (B1-B25). Al the models were cast in plaster. In CAD/CAM group, the digital impressions were obtained by optical scanning, then designed through computer and cut directly by NC miling machine. In cast group, metal ceramic crowns were made by the lost wax casting method. When crowns were al seated on the working dies, the marginal gaps were copied with light silicone rubber and then embedded with occlusal silicone rubber. The thickness of crown marginal gap was measured with a stereo microscope. RESULTS AND CONCLUSION:The average vertical clearance was (34.67±7.48)μm of CAD/CAM group, while (53.70±9.64)μm of the cast group; the difference was statisticaly significant between two groups (P < 0.05). The average level clearance was (37.61±7.63)μm of CAD/CAM group, while (53.02±10.65)μm of the cast group, and the difference was statisticaly significant between two groups (P < 0.05). Experimental findings suggest that, the marginal adaptation of single cobalt-chromium PFM crowns cast produced by 3 Shape CAD/CAM systems is clinical acceptable (< 120μm), and CAD/CAM systems of metal casting is obviously better than the lost wax casting in building metal based crowns with adaptable margin.

Objective To study the psychological defence (PD) and coping style (CS) of the patients suffering depressive episode (DE).Methods 104 cases of the experimental group and 104 cases of the control group,which were stratified sampled,had been investigated by applying defensive style questionnaire (DSQ),coping style questionnaire(CSQ).Results The total score of the immature PD of the experimental group(5.19±0.73) was significantly higher (t =2.93,P＜ 0.05) than that of the control group (4.41 ± 0.76).In the immature mechanism,withdrawal,somatization,avoiding,passive aggression were significantly higher,but the complaints and fantasy were significantly lower.The total score of mature PD of the experimental group(4.49±0.61) was significantly lower (t=-6.02,P＜0.01) than that of the control group(6.01±0.85).For the mature mechanism,sublimation and humor were lower and the repression was higher.And for the CS,problem solving,consulting and rationalization scores were significantly lower than those of the control group(t=-4.58,P＜0.01 ; t=-4.49,P＜0.01; t=-4.01,P＜0.01).The self-accusation,retreat scores were significantly higher than those of the control group(t=8.21,P＜0.01; t=5.31,P＜0.01).Conclusion Patients suffering DE are apt to use immature PD and CS.To increase the therapeutic effect,the style of the patients' PD and CS should be highlighted,and it is necessary to take steps to guide the patients to use mature PD and CS.

Objective To express a mutated insulin gene in HepG-2 cell line to further research of insulin gene therapy. Methods Native human insulin cDNA was obtained from fetus pancreas with RT-PCR. Furin consensus cleavage sequence was introduced into proinsulin cDNA with site-directed mutagenesis (overlap extension PCR), and the new sequence was named as INS/furin. Subsequently, INS/furin was subcloned into the multiple clone sites of plasmid p(G1RE)3BP-1Luc. The new plasmid p(G1RE)3BP-11?furin was identified with the method of enzyme digestion by Hind Ⅲ and EcoR V. HepG-2 cells were transfected with the plasmid p(G1RE)3BP-11?furin by liposome-mediated method. The transfected HepG-2 cells were incubated for 48h in a glucose-containing medium (25mmol/L), and then the conditioned media were collected and HepG-2 cells were harvested respectively. The expression of INS/furin mRNA in transfected HepG-2 cells was examined by RT-PCR, the regained DNA was sequenced and insulin in conditioned media was investigated by radioimmunoassay. Results Two enzymes, Hind Ⅲ and EcoR V, digested p(G1RE)3BP-11?furin, and 2 fragments with length of 260 bp and 4 700bp, were obtained. The 260bp fragment was identified as insulin/furin, indicating that the target gene had been successfully inserted in specific sites. RT-PCR showed that insulin/furin mRNA was expressed in transfected HepG-2 cell, and the regained DNA was confirmed as insulin/furin by sequencing; while insulin was detected by radioimmunoassay in conditioned media. Conclusion The recombinant mammalian expression plasmid p(G1RE)3BP-11?furin has been successfully constructed, and transfected into HepG-2 cells, which therefore may efficiently secrete bioactive insulin.

Health is an important component of human capital,and it is the premise and basis of other forms of human capital.This paper clarifies the impact of health on individual family income from several aspects.

The situation of investment in health is a measure of socio-economic and cultural development of a country or region.The health outcome from a certain amount of health costs is the economic benefits of investment in health.The World Health Organization has made "put investment in the field of health to promote economic development," a new development strategy for the purpose of investment in health,expanding domestic demand and the development of health which could be the cause of national macro-economic development.This paper briefly describes the impact of health investment on China's economic development from several aspects.
