BACKGROUND:As mechanical load-bearing tissues, tendons have unique biomechanical characteristics. Mechanical loading is necessary in tendon development, and the tendon can alter its structure and biological behaviors in response to the various mechanical loading conditions. OBJECTIVE: To fuly understand the healing process and biomechanical properties of the damaged tendon so as to know the researching progress in the role of stress in the tendon healing process. METHODS: An electronic search of Chinese Biomedical Literature Database and PubMed databases was done for colection of reviews and papers addressing stress effects on tendon healing, and then we analyzed the role of stress in the healing process of tendon from the micro and macro levels. RESULTS AND CONCLUSION:Totaly 59 relevant articles were enroled. Tendon is sensitive to stress, and it can change its structure and biological reaction in response to different stress loadings. Proper stress stimulus to the tendon is necessary to the tendon development and healing. How to achieve a good balance between the lowest (resulting in alienation effect) and the highest stress loadings (resulting in minimaly invasive injury) during the clinical tendon healing is a chalenge. At present the treatment of tendon injuries is stil a huge chalenge to clinicians, and the vast majority of tendon injuries belong to tissue healing.

BACKGROUND:Tissue-engineered tendons have been used to repair the damaged tendon tissue. Use of tissue-engineered tendons for repair of tendon injury has become a hot spot in this research field. OBJECTIVE: To elaborate the types, advantages and disadvantages of seed cels, the design method, advantages and disadvantages of scaffold materials, and the factors that induced the formation of tendon, so as to promote the optimization of each joint, al of which benefit for mature construction of tissue-engineered tendons. METHODS: The related reviews and paper reports of tendon tissue engineering published from January 2000 to January 2015 were retrieved from Chinese Biomedical Literature Database (CBM), China Knowledge Resources Database (CNKI) series database, Chinese Citation Database and PubMed database. The key words were “tissue engineering; tendon; tendon defect”. The research progress of seed cels, scaffold material and induction factors were analyzed. RESULTS AND COMCLUSION:The recent research of tissue-engineered tendons for repair of tendon injury has been summarized. Seed cels, scaffold, induction factors were discussed. Tendon stem cels, as a kind of seed cels, are currently the first choice in the process of tissue engineering tendon research, because tendon stem cels have the homology of the homogenous or autologous tendons and possess strong differentiation and proliferation capacities. However, there have been no systematic schemes regarding acquisition and proliferation and culture of tendon stem cels. The currently designed tissue-engineered tendons cannot meet the clinical requirements because of poor mechanical properties of tendon tissue, poor integration with the host tissue, being susceptible to degradation in late period and functional disuse. Induction factors are the laft key factors for tissue-engineered tendons for repair of tendon injury. The selection and use of induction factors are prerequisites for the regulation of tendon tissue development. But the categories of induction factors and the association and interrelationship between induction factors have not been fuly clear and studies are needed to further investigate these uncertainties.

Objective To analyze the antibody titer value of indirect haemagglutination test(IHA)in 135 confirmed acute schistosomiasis patients,so as to provide the evidence for improving the diagnosis and treatment of acute schistosomiasis. Meth-ods A total of 135 acute schistosomiasis inpatients were selected from 2001 to 2006. They all received the IHA antibody titer de-tection,and the correlation among the age,incubation period,and hospitalization days was calculated. Results The antibody titers of IHA were higher than 1:320 in all the cases. The percentages of 1:640,1:1280,1:2560,1:5120 and 1:10240 were 1.48%,28.15%,35.56%,20.00%,and 14.81%respectively. The mean age was(47.70 ± 14.58)years,average incuba-tion period was(38.03 ± 4.59)days and mean hospital stay time was(15.08 ± 3.79)days. The antibody titer value had no corre-lation with the age distribution(r=0.109,P>0.05). There was a negatively correlation between the antibody titer value and in-cubation period,(r=-0.558,P<0.01),there was a positive correlation between the antibody titer value and hospitalization time(r=0.791,P<0.01),and there were significant differences among different groups(F=17.07,64.53,both P<0.01). Conclusions The antibody titer of acute schistosomiasis cases detected by IHA is 1:640 and above. There is no correlation be-tween the antibody titer value and age,but the antibody titer value is higher,the incubation period is shorter and hospitalization time is longer.

Objective To investigate the effects of gastroesophageal reflux and duodenoesophageal reflux on expression of p53, Cyclin D 1, p21 and p16 in esophageal epithelium in rats. Methods Rat models of gastroesophageal reflux (G), duodenogastroesophageal reflux (DG), duodenoesophageal reflux (D) and control group (C) were set up by operations. All esophagi were draw at 1,2,4 week after operation and the expressions of p53, Cyclin D 1, p21 and p16 protein were measured by immunohistochemistry analyses. Results The levels of p53, Cyclin D 1 protein expression in reflux groups were significantly greater than those in C group, and those in D and DG group were significantly higher than in G group. The expressions of p16 protein were similar in each group. The number of p21 positive cells in D and DG group was fewer than C group at 4 week, and the staining pattern correlated well with p53 staining. Conclusions Both gastric juice and duodenal contents can change expression of p53, Cyclin D 1, p21 protein in esophageal epithelium, but not that of p16. The effects of duodenal contents is stronger than gastric juice. The changes of above genes expression may associate with the pathogenesis of reflux esophagitis and its complications.
