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.

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.

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.

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.

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.

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.

Objective To investigate the ultrasonographie characteristics of basal cell adenoma in salivary gland and to improve the coincidence of ultrasound diagnosis for the tumor. Methods The ultrasonographic characteristics for 31 cases of basal cell adenoma which were pathologically confirmed were analyzed and summarized combining with its pathological characteristics retrospectively. A differential diagnosis between basal cell adenoma and pleomorphic adenoma was also made. Results Basal cell adenomas of salivary gland showed low and equivalent internal echoes,sometimes with colliquation in their substantial component. They showed enhanced posterior echo,middle hardness, clear boundary and regular shape. Color Doppler flow signals were also found in the center or periphery of the tumors. Conclusions The ultrasonic manifestation of the basal cell adenoma has its own characteristics,which is complied with its pathological basis. The combination of ultrasonography and clinical information is conducive to differentiate basal cell adenoma and pleomorphic adenoma of salivary gland.

OBJECTIVE: To evaluate the role of total glucosides of peony (TGP) as adjuvant therapy for prevention of cardiac allograft rejection in rats. METHODS: Rats with cardiac allograft were randomly divided into control group, tacrolimus-treated group, TGP-treated group and tacrolimus plus TGP-treated group. Graft survival time was observed. Allografts in some cases were examined by histological study seven days after transplantation. At the same time, the levels of CD4(+) and CD8(+) T cell subsets in peripheral blood were examined by using flow cytometry; the hepatic function and renal function of recipients were also tested. RESULTS: The graft survival time of the tacrolimus-treated group and tacrolimus plus TGP-treated group was (11.14+/-1.57) d and (13.57+/-1.99) d, respectively. The graft survival time of the tacrolimus plus TGP-treated group was longer than that of the tacrolimus-treated group (P<0.05). The histological study showed that the rejection of the tacrolimus plus TGP-treated group was slighter than that of the tacrolimus-treated group. The levels of CD4(+) T cell subset in the peripheral blood of the tacrolimus-treated and tacrolimus plus TGP-treated groups were (38.71+/-5.15)% and (32.43+/-4.39)% respectively 7 days after transplantation. The level of CD4(+) T cell subset in the tacrolimus plus TGP-treated group was lower than that in the tacrolimus-treated group (P<0.05). The level of CD8(+) T cell subset and the hepatic and renal function had no significant differences between the tacrolimus-treated group and the tacrolimus plus TGP-treated group. CONCLUSION: Effects of tacrolimus plus TGP in prevention of rejection are better than tacrolimus monotherapy in rats with cardiac allograft and without increasing side effects.

Objective To study the connection between vascular endothelial growth factor(VEGF) and pool prognosis in nephroblastoma.Methods Serum VEGF was measured with immuneohistochemical(ELISA) methods in 35 children of nephroblastoma at preope-ration,1 week,2 weeks after surgery respectively. Simple visiting happened after surgery 4,8,16,32 weeks.The countrol group was 35 healthy children. Result Before surgery,the median VEGF in the children was (89.47?22.45) ?g/L.After surgery 1 week,2 weeks,levels in the children fell significantly to (2.75?0.31) ?g/L,(1.52?0.18) ?g/L.There was a significant difference compared with preoperation ( t =4.125 P
