Objective To explore the operative cooperation and nursing points of holmium laser lithotripsy under percutaneous nephroscope. Methods A retrospective study was carried out to investi-gate the operative cooperation and nursing of 38 patients receiving holmium laser lithotripsy under percuta-neous nephroscope in our hospital from March 2006 to August 2007. Results Stones were completely cleared in 31 patients at first holmium laser lithotripsy,in 5 patients at second holmium laser lithotripsy,in 2 patients at third holmium laser lithotripsy. One patient complicated with water intoxication and septicemia. Operation time ranged from 50 to 190 minutes,blood loss volume reached 50 to 200 ml with a average of 100 ml.No blood transfusion was needed during the operations and no secondary hemorrhage was seen postoperation. Double J catheter was inserted and indwelled for 30 to 60 days with a average of 38 days. Postoperative follow-up was satisfying. Conclusions Holmium laser lithotripsy under pereutaneous nephroscope possesses the advantages of little trauma,hemorrhage and complication and quick recovery.It is the best choice for treatment of calculus in urinary system.

Objective To discuss diagnosis and surgical treatment for chronic lymphocytic thyroiditis (CLT). Methods Records of 70 patients who were diagnosed as CLT from 2005 to 2009 were retrospectively reviewed. They were divided into two groups according to pathological results. Results There were 6 patients of CLT accompanying with papillary carcinoma. The rest 64 patients were diagnosed as CLT accompanying with benign nodules. All cases were confirmed by pathology and treated with operation. Conclusions Coexistence of nodules which can not be excluded from carcinoma is the main reason for surgical treatment in case of CLT. CLT patients especially for those associated with single nodule and/or microcalcification inside nodules should be given surgical treatment. The operative method depends on pathological results during operation.

OBJECTIVE:To observe the efficacy and safety of rebamipide triple therapy in the treatment of gastric ulcer with bleeding. METHODS:130 patients with gastric ulcer with bleeding were randomly divided into control group(65 cases)and obser-vation group(65 cases). Control group received Omeprazole enteric-coated capsule 20 mg,orally,twice a day+Aluminum magne-sium carbonate tablet 500 mg,orally,once a day;observation group was additionally received Rebamipide tablet 0.1 g,orally,3 times a day. They were treated for 12 weeks. Clinical efficacy,remission time of belching,abdominal pain,bloating,hematemesis/hematochezia,clinical symptom score before and after treatment,rebleeding and the incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,remission time of symptoms and signs were significantly shorter than control group,the incidence of rebleeding was significantly lower than con-trol group,with statistical significances (P<0.05). Before treatment,there was no significant difference in the clinical symptom score (P>0.05). After treatment,the clinical symptom scores in 2 groups were significantly lower than before,and observation group was lower than control group,with statistical significances (P<0.05). And there was no significant difference in the inci-dence of adverse reactions (P>0.05). CONCLUSIONS:Rebamipide triple therapy shows obvious short-term efficacy in the treat-ment of gastric ulcer with bleeding,which can effectively improve patients'gastrointestinal symptoms,reduce rebleeding risk,and does not increase the incidence of adverse reactions.

Objective To investigate the expressions of Bcl-2 and Bax protein in the renal tissues of patients with lupus nephritis(LN)and their role in the pathology alteration of LN.Methods During 2003-01～2003-04 immunohistochemical staining was used to detect the expressions of Bcl-2 and Bax in renal tissues of 44 cases of LN in the First Affiliated Hospital of Guangxi Medical University.Their relationship with pathology was also observed.Results (1)The expression of Bcl-2 and Bax was significantly increased and both were positively correlated with the grade of intraglomerular cell proliferation and proliferating cell nuclear antigen(PCNA)positive glomerular cells.(2)The expression of Bcl-2 in interstitial cells was significantly increased and positively correlated with the degree of interstitial infiltration of inflammatory cells.(3)The expression of Bax in the tubule of LN was increased and was positively associated with tubulointerstitial lesions.Conclusion There is abnormal expressions of Bcl-2 and Bax in renal tissues of LN.Overexpression of Bcl-2 in renal tissues of LN might play an important role in the process of glomerular hypercellularity and interstitial infiltration of inflammatory cells.Overexpression of Bax in tubular ducts is correlated with tubulointerstitial lesions.

Objective To study the clinical application of ureteral grasping forceps in ureteroscopic operations. Methods A total of 74 cases treated under ureteroscope by using ureteral grasping forceps from April 2001 to July 2003 in this hospital was retrospectively analyzed. There were 25 cases of polyp resection and pneumatic lithotrity, 21 cases of rigid guidance through ureteral retortion, 19 cases of ureteral stricture dilation and ureteroscopic lithotrity, 3 cases of whole ureteral membranous obstruction, 3 cases of ascending shift of double “J” tube, 2 cases of intraoperative biopsy,4 cases of removal of double “J” tube with urethral stricture,and 2 cases of pneumatic lithotrity. Results The procedures were successfully accomplished in 69 cases.A conversion to open operation was required because of malfunction of ureteral grasping forceps in 1 case, and ureteral perforation occurred in 4 cases. Conclusions Ureteral grasping forceps is indispensable in ureteroscopic operations, which should be skillfully operated.

Objective To investigate the efficacy of paracentesis using jugular vein indwelling catheter (Angiocath) in the treatment of simple renal cysts. Methods We retrospectively analyzed clinical data of 61 patients with simple renal cyst treated by Angiocath paracentesis combined with sclerosing agent injection under the guidance of ultrasonography. Results Fifty-two patients were cured on one session, while a recurrence was seen in 9 patients, among which 6 patients were cured by a re-paracentesis and 3 frequently recurrent patients were cured by the unroofing operation. No complications occurred except for 3 cases of mild transient hematuria. Conclusions Paracentesis using Angiocath in the treatment of simple renal cysts is minimally invasive, safe, effective and economical.

Purpose:Our experiments are dealing with the affect of docosahexaenic acid(DHA) in doxorubicin to cytoxicity effect of MDA-MB-435s, which is of the anti-human breast cancer and whether it is one of the effect mechanisms that it via the lipid peroxidation of DHA.Methods:Add different match such as anti-cancer drugs?PUFAs?oxidan system of sodium ascorbate and ?-methy-1.4-naphoqui-none?antioxidant of Dl-?-tocopherol and so on to the culture cell line of MDA-MB-435s each 24 hours for 6 days, estimate MDA by TBA with cell extracts and estimate the contents of NO via nitrite salt spectrophotography, then draw out a dosage-effect correlation straight line among contents of MDA,NO and cytoxicity. Mitox is used as contraposition to the peroxidation of ADM which is enhanced by DHA for peroxidation of mitox is low.Results:There have been obvious changes on the contents of MDA of the lipid peroxidation has paralled increased while NO has decreased. There is recitilinear correlation relationship among the contents of MDA and NO from cell extracts and the cytoxicity.Conclusions:It is obvious that DHA can add the cytoxicity of cell line of MDA-MB-435s with ADM, particularly after add non-cytoxicity oxidant. It is lipid peroxidation of oncocyte that one of the mechanisms of DHA can enhance anti-breast cancer effect of ADM.

Objective To study the diagnostic value of 3 dimentional CT reconstruction in upper urinary tract obstructive diseases. Methods 37 patients with upper urinary tract obstructive diseases underwent thin slice helical CT scan and 3 dimentional reconstruction of the urinary tract as well as 3 dimentional CT angiography when needed. Results All the cases have been definitely diagnosed including ureteral carcinoma in 8, bladder carcinoma in 2, ureteral calculi in 9, benign ureteral stricture in 7, congenital malformation in 7 and pelvic tumor in 4.All the patients except those with pelvic tumors underwent surgical intervention and the diagnosis were confirmed.The operative findings were in concord with the helical CT results. Conclusions 3 dimentional CT reconstruction of the urinary tract can provide distinct urinary tract images and helps determining the site and the cause of the obstruction. Compared with other methods, the procedure has the advantages of high resolution, rapid imaging and low invasiveness. It might become the most valuable means of detecting upper urinary tract diseases.
