Extensive informed consent is a special form of informed consent.In foreign countries,the applica-tion and implementation of extensive informed consent has enhanced the circulation rate of biological samples in fu-ture research and promoted the development of the clinical research of biological samples.But it also has caused some ethical issues because of weakening informed such as:obtaining the information about the subject not in time,the research risks unknown and quiting research not in time.At present,Europe and the United States have conducted a lot of research in the implementation conditions,informed content and framework,providing a strong support for the practice of extensive informed consent.The practice of extensive informed consent has become the development direction of the biological samples research in our country.The author compared the social environ-ment and theoretical research at home and abroad and thought that our country must practice and implement it on the basis of social recognition,the improvement of ethical review mechanism and legislative protection.

With the rapid development of network technology,the data sharing and health research provides an efficient and convenient way for medical research and clinical guidance.In order to know patients' opinions on informed consent and data sharing,we investigated first-class hospitals in the coastal and inland areas with a total of 397 patients participating the questionnaire on clinical health and data sharing,reusing the remaining clinical blood samples in scientific researches,and the acceptance degree of broad consent investigation and related influencing factors.It was found that patients with strong consciousness of informed consent right tended to choose a simpler way of informed consent based on the analysis.Patients preferred social benefits than personal benefits with a strong spirit of dedication to the community.Medical institutions in China rarely applied broad consents and took relervant summative researhes,compared with the European and American countries' promotions at the national level.The research afforded the evidence,from most of patients' point of view to ethics committee in the review of such kind of studies to understand the public data sharing in privacy protection and broad consent of the individual opinion,in order to facilitate the rational development and promotion of health data sharing in China ethically.

Objective To study the effects of density,phosphorous(P),and nitrogen(N)fertilizers on yield and quality of Andrographis paniculata.Methods Randomized block design in yield was used and HPLC was used to analyze the content of andrographolide and dehydroandrographolide.Results Plant height,fresh weight,dry weight,content of dehydroandrographolide were influenced significantly by density.The quality character and economic yield of content of andrographolide,dehydroandrographolide,total content of both andrographolide and dehydroandrographolide were significantly influenced by P nutrition.The economic yield of dry weight,content of andrographolide and dehydroandrographolide,and total content of both andrographolide and dehydroandrographolide were influenced significantly or extreme significantly by N nutrition.P and the interaction of P and N fertilizer extremely influenced the economic yield.The relative influences between plant weight and dry weight was extremely significance,that between quality character and quality character,that between quality character and economic yield were significant or extremely significant.Conclusion When planted with 1.8?105 /hm2,fertilizered with P2O5 540 kg/hm2 and pure N 225 kg/hm2,the hightest economic yield is gained.

Objective To investigate the effects of the thickness of the adhesives(3 M ESPE RelyX ARC)on the internal stress distribution of the IPS Empress Ⅱ full-ceramic crowns by using Finite Element Analysis(FEA).Method A dummy Empress Ⅱ ceramic crown restoration of the mandible right first molar was prepared according to standard dental process.Followed by micro-CT scanning,four 3D numerical models with cement thickness 60,90,120 and 150 μm were established respectively.The models were subjected to four loading conditions and stresses in veneer and core layers were presented.Result Numerical results indicate that when adhesive thickness increases from 60 μm to 90 μm,the maximum principal stress either in veneer or core decreases.However,when thickness increases to 150 μm,stress variation trends differ from adhesives.Conclusions The normal stresses in adhesives remain a low level when the thickness varies from 90 μm to 120 μm,while the shear stress is less sensitive to the thickness when it exceeds 90 μm.There is an optimal thickness which can reduce the tensile stress in the core and veneer.Attention should be paid to the shear strength of the adhesives since the shear stress could cause failure in the adhesive layer.

Objective To evaluate the efficacy of different duration of low-carbohydrate diet (LCD) intervention on glycosylated hemoglobin (HbA1c) in type 2 diabetes mellitus (T2DM) patients. Methods Randomized controlled trials (RCTs) of LCD intervention in T2DM patients were collected in the databases such as MEDLINE, PubMed, OVID, China National Knowledge Infrastructure, China Scientific Journal Database by VIP, Wanfang database, et al.Data were analyzed by RevMan 5.3 version. Results Eight RCTs were included. The results of Meta-analysis indicated that the effects of lowering HbA1c by LCD intervention for three (Z=2.28, P<0.05) and six months (Z=14.99, P<0.01) were better than other diabetes diets, but there was no significant statistical difference between one (Z=0.65, P=0.51) and two years (Z=1.62, P=0.10). Conclusions Hypoglycemic effect of short-term LCD was better than other diabetes diets, but long-term effect was similar between them. LCD was a therapeutic diet suitable for T2DM patients.

Objective To investigate the correlation between the mutation in serum lipoprotein-associated phospholipase A2(Lp-PLA2) Ile198Thr, Val279Phe and cerebral infarction in Chinese Han population of Jiangsu Province. Methods One hundred fifty patients with cerebral infarction and 100 healthy controls in Chinese Han population of Jiangsu Province were recruited. The correlation between Val279Phe and Ilel98Thr mutation in Lp-PLA2 gene and cerebral infarction was analyzed using polymerase chain reaction and denaturing high performance liquid chromatography. Results The Val279Phe genotype and the mutant allele frequency in the cerebral infarction group were significantly higher than those in the control group (χ2 were 6. 31and 5. 32, respectively, all P ＜0. 05), and there was no significant difference between the Ile198Thr genotype and the mutant allele frequency in the control group (χ2 were 0. 039 and 0. 037, respectively, all P ＞0. 05). Conclusions The Val279Phe mutation in Lp-PLA2 gene may be a genetic risk factor for cerebral infarction in Chinese Han population of Jiangsu Province.
