Titanium & titanium alloy are popular in dentistry as dental material because of their good mechanical properties and extremely good biocompatibility. The bonding strength between the titanium and the resin agent is the decisive factor in evaluating the success of resin-bonded restoration. Appropriate surface treatment on the titanium is an effective way to reinforce the bending strength. The purpose of this review is to summarise the relevant studies and introduce some latest findings.

Objective To evaluate rhBMP-2/20%β-TCP/PDLLA complex biological properties.Methods Preparation of casting salting was carried out using three-dimensional porous 20% rhBMP-2/β-TCP/PDLLA. 24 4-month-old healthy male New Zealand rabbits were randomly divided into A,B groups of 12,according to the method described in Boden production L4,5 intertransverse process fusion model. A group was embedding rhBMP-2/20%β-TCP/PDLLA complex,and B group was implanted autogenous iliac bone block. Animals were killed according to postoperative time(3 weeks,6 weeks, 12 weeks) ,for gross observation, X-ray observation of the formation of new bone, artificial bone degradation, and early histological manifestations. Results Composite artificial bone and autologous iliac bone graft were able to achieve good spinal fusion,artificial bone graft where there is no inflammatory response,but also in new bone formation,while reshaping the gradual degradation of carrier material. Conclusions 20%β-TCP/PDLLA showed good biocompatibility. Its structure and micro-environment created by its degradation were conducive to play a role for the rhBMP-2. β-TCP/PDLLA had strong activity in inducing bone and good bone fusion ability,and it was a promising bone graft substitutes, which fusion power was stronger than that in autologous iliac bone graft.

The‘prevention and early treatment of diseases’conception as‘Huangdi Neijing’suggested,is the highest academic realm among the Chinese medical theory,it flows through the entire process of Chinese medical theory and diseases prevention.Four aspects of the prevention conception manifested in the process of Chinese medical prevention of diseases are: Taking preventive measures before confirmed diagnosis(health cultivation),impeding diffusion after confirmed diagnosis, deterring diffusion from deterioration,and restraining deterioration from being malignant.The malignant causal chain conversion of the coexistence of asthenia and sthenia is considered as the inducing links of critical illness’occurrence,evolution and transformation.Therefore,to intercept the malignant causal chain conversion comes to the key technique of Chinese medical remedy for critical illness.The‘prevention and early treatment of diseases’conception must impenetrate the versal process of treating critical illness.The overall clue and method of Chinese medical remedy for critical illness is to identify and grasp the vital contradiction and each respect of the malignant causal chain conversion which concurs with the evolution of the critical illness,simultaneously utilize the method which combined the prevention in etiology and pathogenesis with the remedy in etiology and pathogenesis,then actuate the pathologically changed organism to extricate from critical conditions at the first opportunity, finalizing with convalescence and recuperation thereafter.

Bone marrow mesenchyma stem cells are stem cells that occupy self-renewal and multiple differentiations into cells,which have been recognized as the optimal origin for liver cell.With an increasing number of studies addressing marrow mesenchyma stem cells,more attention has been drawn to treating liver disease using the stem cell and organ reconstruction,especially seeks for the appropriate in vitro induction system.This paper comprehensive summarized the differentiation characteristics of marrow mesenchyma stem cell under many kinds of micro environment,and explains the superiority,as well as existence question of each kind of induction condition.

Objective To study the reaction mechanism of ginsenosides in red ginseng processing. Methods The major constituents of ginsenosides were assigned by HPLC/MS/MS data. Ginsenosides (including protopanaxadiol, protopanaxatriol, and oleanolic acid type) of white ginseng and red ginseng were compared by HPLC/MS data. Results Ginsenosides were produced from esterolysis of corresponding malonyl ginsenosides in red ginseng processing. Another reaction of malonyl ginsenosides in red ginseng processing was decarboxylated to produce corresponding acetyl ginsenosides. Hydrolysis of glycosidic bond at C_(20) and isomerous reaction of C_(20) were the main reaction of dammarane type ginsenoside. High degree of esterolysis and glycosidic bond hydrolysis of oleanolic acid type ginsenosides all occurred during the red ginseng processing. Conclusion Great changes of ginsenosides have been obviously found in processing ginseng to red ginseng. Special constituents of red ginseng could be produced in ginseng processing.

OBJECTIVE:To observe the effect of acyclovir on neurological function and cytokines of children with viral menin-gitis. METHODS:Totally 70 children with viral meningitis were randomly divided into control group and observation group. All children were given routine treatment,including defervescence,reducing intracranial pressure and regulating water and electrolyte balance,etc. Based on it,the control group was treated by Ribavirin glucose injection 15 mg/kg,iv,bid;observation group was treated by Acyclovir glucose injection 5 mg/kg,iv,tid. The course for both was 7 d. The clinical data was compared,including the vascular endothelial growth factor (VEGF),matrix metalloproteinase-9 (MMP-9) in cerebrospinal fluid (CSF) and serum,insu-lin-like growth factor-Ⅱ(IGF-Ⅱ) and insulin like growth factor binding protein-3(IGFBP-3) in CSF before and after treatment and the incidence of adverse reactions. There were no obvious adverse reactions during the treatment. RESULTS:After treatment, the VEGF and MMP-9 in serum and the VEGF,MMP-9,IGF-Ⅱ and IGFBP-3 in CSF in 2 groups were significantly lower than before,and observation group was lower than control group,with significant differences(P<0.05). There was no adverse reactions in 2 groups during the treatment. CONCLUSIONS:Compared with ribavirin,acyclovir can more obviously improve the neurological function and cytokines of children with viral meningitis,with similar safety.

[Summary] Gender difference study of meniscus injury shows certain clinical significance in understanding epidemiologic characteristics of meniscus injury .Several large amount case studies demonstrated that the risk of meniscus tears was significantly higher in male than in female .However , in certain kinds of sports and special types or locations of meniscus tears , especially in medial meniscus posterior root tear ( MMPRT ) , there were more females than males .Further large amount case studies were needed for a deeper understanding of meniscus tears .In this paper,we reviewed the current situation and progress of gender difference of menisus tear .

When entering the clinical teaching phase,the last step before graduation and assignation,medical students are given more chances to contact with the society.This is an important period that the educators should care more about and communicate more with the students in order to foster their career mentality.Our suggestions are as follows,1.Emphasizing the clinical ability.The basic clinical skills are the premise and guarantee that a medical student is able to diagnose and cure,and also the main content of quality education and evaluation for medical students,2.Emphasizing the formation of the research-type learning habit and the innovative thinking modes.The cultivation of the research-type learning ability is a symbol of innovative talent,as well as an essential quality.An innovative thinking training consists of different thinking,converse-thinking,role-changing thinking,divergent thinking and critical thinking.3.Must correctly deal with the relationships between having a clinical training or preparing for the postgraduate entrance examination and getting a job.The educators should help the student form virtues of professional dedication,diligence and positive learning attitudes,strengthen their sense of social responsibility and obligation,and establish correct world outlook,outlook on life and values.4.Must enhance the nurturance of medical students' professional ethics.In the clinical practice,the students' behavior must be regulated.What's more,they should learn to be a qualified doctor who respect,be responsible for and care for the patients.
