Objective To observe the analgesic effect of progressive muscle relaxation training (PMR) and compound lidocaine cream in hemodialysis patients undergoing puncturing on arteriovenous fistula.Methods 96 hemodialysis patients undergoing puncturing on arteriovenous fistula were randomly divided into the progressive relaxation training group (group A),compound lidocaine cream group (group B),progressive relaxation training and compound lidocaine cream group (group C),and the blank control group (group D),with 24 patients in each group.Compound lidocaine cream were applied on the central puncture point 60 minutes before operation in group B and group C,and the patients of group A and group C were conducted with progressive relaxation training before puncture and sleep,while no intervention were assigned to group D.The pain of each patients were measured in 10 minutes with Visual Analog Scale(VAS).Results The pain scores were respectively (3.042 ± 0.999) in group A,(2.500 ±0.978)in group B,(1.333 ± 0.817) in group C and (5.042 ± 1.122) in group D.The AVOVA under the significant level of 0.05 for factorial date indicated that the main effect of factor A (progressive relaxation training) was statistically significant and the main effect of factor B (compound lidocaine cream) was also statistically significant.And that statistically significant interaction between the two factors was found,too.Conclusions Compound lidocaine cream with progressive relaxation training could alleviate the pain during puncturing arteriovenous fistula from hemodialysis significantly and was better than single use of each method.

Objective To explore the clinical significance of gastric hyperplastic polyp pits under magnifying endoscopy. Methods Summary confirmed by magnifying endoscopy and pathological examination gastric hyperplastic po]yp's performance of magnifying endoscopy,Hp positive and the results of pathology during February 2004 to De-cember 2006. Results 55 patients found 116 gastric polyp,41.4% (48/116) with type A,26.7% (31/116) with type B,19. 8% (23/116) with type C,8. 6% (10/116) with type D,2. 6% (3/116) with type E,one case gastric pits blurred(type F) 0. 9% (1/116). 4 cases with type E and type F found moderate-severe atypical hyperplasia. Conclu-sion Gastric hyperplastic polyp pits with type E and type F ,their results of pathology to display atypical hyperplasia.

OBJECTIVE: To establish an HPLC method for the determination of chloramphenicol content in chloramphenicol vaginal soft capsule.METHODS: The sample was separated on Kromasil C18 column with 0.1% sodium heptanesulfonate solution-acetonitrile(77∶23) as mobile phase at a flow rate of 1.0 mL?min-1.The detection wavelength was set at 272 nm;The sample size was 10 ?L and the column temperature was maintained at 30 ℃.RESULTS: The linear range of chloramphenicol was 0.079～0.113 mg?mL-1(r=0.999 6) and its average recovery rate was 99.38%(RSD=0.42%).CONCLUSION: The method was proved to be specific,sensitive,accurate in results and suitable for the determination of chloramphenicol content in chloramphenicol vaginal soft capsule.

One hundred and eleven cases of male reproductive diseases including epididymis,testi tis,cyst of epididymis,cryptochidism and varicocele were scanned with 10 MHz bifunctional soft probe.Utilization of high frequency probe may differentiate distinctively testitis from hemorrhage of testis and may easily find the locatipn and structrure of the eryptochidism.The combined use of 2 dimensional ul-trasonography and Doppler technique may be helpful fo detect the extent of varicocele and to evaluatethe postoperative efficacy.High resolution ultrasonography has been an important method for diagnos-ing the scrotal disease and the main indicator to decide whether the surgical or nonsurgical treatment should be undertaken.

This paper presents 231 cases of carcinoma in the region of the gastric cardia.In 96 of the cases-gastrectomy specimens were obtained,and for the remaining cases biopsy specimens were taken through gastroscopy.The study of cancerous cells in their developing stages in the tissues taken from the neighborhood of the tumours revealed that there were 4 types of histogenesis of gastric-cardia carcinoma:1.cancerous degeneration of cells at the glandular necks in the gastric foveolae;2.cancerous degeneration of a single cell or a few cells of the glandular epithelium;3.dysplasia of the epithelium with-malignant change;4.intestinal metaplasia of the epithelium with cancerous change.It is suggested that dysplasia of the epithelium and intestinal metaplasia of the epithelium accompanied by dysplasia are significant precancerous changes.

Twelve methods of histochemical staining of mucins were compared,and improvemen ts in staining technic was made. Appropriate sodium meta-bisulfite was added to the ineffective Schiff's reagent to recover its staining property. The concentration of alcian blue was decreased from 1 % to 0.5%. Neutral red as the contrast stain was replaced by VG. The result of this study showed that this series of staining technics was simple to carry out, low cost, more specific, and suitable for any pathology department to use for detection of mucin in biopsy specimens of gastric mucosa.

155 endophytic fungi were isolated from Equisetum arvense L.,Impatiens chinensis L. and Myriophyllum verticillatum L. They were identified to 26 taxa. The antagonistic activities of these isolates against 6 isolates of plant pathogenic fungi were tested on the medium,and 37(23.9%) isolates were activitive against one or more phytopathogens. The percentage of antifungal active isolates from E. arvense L.,I. chinensis L. and M. verticillatum L. were 13.9%,29.2% and 37.1%,respectively. It was lower than that of terrestrial plants. The active isolates were mainly belonging to 5 genera including Cladosporium,Trichoderma and Geotrichum.

Objective To measure the quality of manual wheelchairs made in China. Methods 20 wheelchairs was tested with ISO 7176-8, focused on the static strength, impact strength and fatigue strength. Results 8 (40%) wheelchairs passed the test. Conclusion The fatigue strength is the key factor of the wheelchair quality.

This paper introduces the standards and the market conditions of wheelchair in China, as well as the general quality of products of wheelchairs from the quality supervision and spot check, and puts forward some suggestions on how to improve the quality of wheelchairs in China.

Objective To investigate knowledge, attitude, and practice of exercise for post-operative breast cancer. Methods 110 postoperative breast cancers were investigated using a self-designed questionnaire which included general condition of patients, knowledge, attitude and practice of exercise after breast surgery. Results The rate of effective response was 98%. The average rate of awareness about postoperative exercise for breast cancers was 87%, and the score of knowledge of intensity and forms of exercise was the lowest, while the announcements of post-operative exercise was the highest. All of the patients presented positive attitude toward exercise, however, some of them indicated that they couldn't insist on it. 41% exercised only in one form, 78% at a low intensity, 41% less than 3 times per week, and 74% at least 30 minutes per session. Only 7% did traditional Chinese medical exercise. Time after surgery correlated positively to general scores (r=0.40, P<0.01), kinds of exercise (r=0.41, P<0.05) and intensity of exercise (r=0.43, P<0.05). Phase of cancer correlated negatively to general scores (r=-0.37, P<0.05) and exercise time (r=-0.38, P<0.05). Conclusion The knowledge on intensity and form of exercise after operation is not popular in post-operative breast cancers.
