Chinese Traditional and Herbal Drugs 1994;0(05):-
Result of Bencaocogical studies on Changpu showed that it originated from two different source, one is Shuichangpu (Asorus calamas) while another is Shichangpu (A.tatarinowii and A.gramineus). Usually, Changpu grown on stony ground was referred to as Shichangpu.Jujiechangpu is a kind of Changpu with 9 nodal rings within an "inch" on its root stock,but that which is used in Northwest China is an cntirely different herb Anemone altaica.

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.

Chinese Journal of Urology 2001;0(06):-
Objective To present the means of localizing the kidney with ectopic ureter in order to provide the reliable ground for surgical strategy. Methods Clinical manifestation study,IVU,SPECT imaging and cystoscopy were conducted.All the 58 patints are female with a mean age of 3.4 years.According to the creteria presented in reference,5 were type Ⅰ,42 type Ⅲ,1 type Ⅳ,8 type Ⅴ and 2 type Ⅵ. Results Operative finding revealed the accurate localization and diagnosis rate of IVU has been 95%(40/42) in type Ⅲ ectopic ureter,B-ultrasonograph 27%(12/53),SPECT 37%(6/16).With the combined consideration of imaging procedures and cystoscopy,the accurate localization and diagnosis rate has been 98%(57/58). Conclusions Combined use of imaging procedures and cystoscopy would improve the localization and diagnosis rate.Cystoscopy is the most reliable except in type Ⅲ ectopic ureter.

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.

Gastroesophageal reflux(G), duodenoesophageal reflux(D) and duodeno gastroesophageal reflux(DG) model and control group(C) were reproduced by operations in rats. Their esophagi were harvested at 1, 2, and 4 weeks after operation. Epithelial cells were stained by PI and assessed with flow cytometry(FCM).The results of FCM were compared in terms of DNA index (DI, the ratio of the G0/G1 peak of the sample cells to that of the spleen lymphocyte of normal rat), proliferating index (PI, the percent of cells in S and G 2 /M in all cells) and aneuploidy (a distinct additional G0/G1peak).PI of D group increased at 2 weeks, and PIs of D and DG group were greater than G group and C group at 4 weeks.DIs and the rates of aneuploidy of all groups were similar at all time points. The results were in accord with the morphological changes. It is concluded that gastric and duodenal contents can induce abnormal proliferation of esophageal epithelium. This effect is obvious in groups with reflux of duodenal contents. Excessive proliferation of the esophageal epithelium might be one of the pathogenetic factors of reflux esophagitis or other relevant complications.

The aim of the study is to evaluate the presence of mutations of p53 gene in RE and esophageal tumor induced by reflux of different gastro intestinal secretions. Gastroesophageal reflux(G), duodenoesophageal reflux(D) and duodeno gastroesophageal reflux(DG) model and control group(C) were reproduced by operations. All rats were given carcinogen (methyl n amyl nitrosamine) and their esophagi were harvested at 20, 26, 40 weeks after the operation. DNA was extracted and PCR amplification for 5, 6, 7, 8 exon of p53 followed by SSCP and AgNO 3 staining were used to detect mutation of p53 gene. It was showed that p53 gene mutations occurred in D and DG group at 20 weeks, and then more mutations were found at 26 and 40 weeks. The total rate of p53 mutation was 15 4% in groupc, 11 7% in G, 31 6% in D,and 33 3% in DG.The changes in the last two groups were significantly more compared with the former two groups.It is suggested that reflux of duodenal contents might promote mutations in p53 gene in esophageal mucosa, and reflux of gastric juice alone has lesser impact on p53 mutation.
