Objective To evaluate the protective effect of taurine on renal injury induced by high energy shock wave in rabbits.Methods Twenty rabbits were divided into the experimental (n=10)and the control group (n=10) at random.Both the groups were exposed to 1500 shock waves at 12.75 KV.In the experimental group, taurine (150 mg/kg) was given intravenously during the shock, while normal saline was given in the controls. Malondialdehyde(MDA) and superoxide dismutase(SOD) in serum were measured and the histological changes, the expression of heat shock protein 70(HSP70) in kidney were determined 3 days after the shocks.Results The level of MDA was(2.2±0.4) ,(2.1±0.4)mmol/L, and the level of SOD was (56.4±9.9) ,(55.8±10.1)μU/L respectively in the experimental and the control group before the shock.There was no significant difference between the two groups(P＞0. 05). After the shock, the level of MDA and SOD was (2.7±0.7)mmol/L, (55.3±5.7)μU/L respectively in the experimental group. There was no significant difference(P＞0.05) compared with the level of before the shock's. While in the control group, the level of MDA and SOD was (5. 7±0. 7) mmol/L, (33. 3±3. 5)μU/L respectively.There was significant difference (P＜0.05) compared with the level of before the shock's. The renal tubule scores of the experimental group and the control group after shocks were 7.2±0.8 and 31.8±1.9, respectively. And the HSP70 scores were 25.2±4.1 and 6.4±0.9, respectively. There was significant difference between the two groups (P＜0.05).Conclusions Taurine can effectively protect kidney from injury induced by high energy shock wave in rabbit.The mechanism may be related with its antioxidant capacity and inducing the synthesis of HSP70 in kidney.

Objective To compare the curative effects of intertrochantefie fractures in aged by two operative methods. Methods 85 cases of elderly patients suffered from intertrechanteric fractures were retrospectively ana-lyzed. Out of the 85 cases,45 cases were treated with dynamic hip screw(DHS) and 40 cases were fixed with Gamma nails. The curative effects and complications were compared simultaneously. Results The total excellent rate was 83.5% in 85 patients,the rates of DHS and Gamma nails group were 77. 8% and 90% (X2 = 2. 84, P 0. 05), re-spectively. The operative time (66. 4 ± 19. 4)min in DHS group were less than the Gamma nail group (875 ± 25.5) rain (t=2. 451 ,P < 0. 05), but the length of surgical incision (19. 6± 5. 1)cm greater than the Gamma nail group (10. 3 ± 4. 7) cm(t = 2. 501, P < 0. 05). The complications of DHS group (11.1%) were significanfly higher than that of Gamma nail group(2. 5%) (X2 =3.94,P<0. 05). Conclusion As long as the physical condition can toler-ate,surgery recommend the use of DHS and Gamma nail surgical techniques in aged patients with intertrechanteric fractures.

Purpose:To determine the efficacy and toxicity of gemcitabine plus cisplatin in anthracyclin- and taxane-pretreated patients with advanced breast cancer. Methods:Chemo-resistance was defined as no response while rece iving first-line and/or second-line chemotherapy. Patients with advanced and c hemo-resistant breast cancer, which was confirmed histologically, received gemc itabine 1,000 mg/m 2 on d1, 8 and cisplatin 25 mg/m 2 on d1-3, every 3 weeks.2 cycles were delivered at least. Results:30 female patients were enrolled in this trial. All pat ients were evaluable for response and toxicity. The median age was 46 years (ran ge, 34-58 years). After 2-4 (median, 3) cycles of chemotherapy, overall object ive response was 50.0%, with 5 CRs (Complete response 16.7%) and 10 PRs (Partial response 33.3%). Stable disease was seen in 13 patients (43.3%), and disease pr ogression in 2 patiens (6.7%). Toxicities included myelosuppression and gastroin testinal reaction mainly. Grade Ⅲ-Ⅳ toxicites developed in 50% patients. Ther e were no treat-related deaths. The median follow-up time was 12.5 (range: 2- 48) months. Median overall survival was 14 months, and median time to progressio n was 10 months. Conclusions:These data indicate that the combination of gemcita bine and cisplatin is an effective treatment for heavily pretreated breast cance r patients with manageable toxicity.

Objectives To study the effect of mesenchymal stem cells on the aging rat kidney and to explore the underlying mechanism. Methods Rat models of senile kidney were built with hypodermic injection of D-galactose daily. Injections of MSCs of 3 × 10<'6>were given to each rat through vena caudalis and CFSE was used as a tracing label to detect the distribution of MSCs in vivo. After 24 h, rats were dissected and their kidneys were frozen for section. MSCs were observed with Fluophot and quantitative analysis of the various parameters of kidney was performed under a light microscope with B12000 image analysis system.The contents of superoxide dismutase (SOD) and malondialdehyde (MDA) in serum and kidney were measured wtih hydroxylamine and chromatometry. The expression of VEGF and P16 mRNA in kidney tissue was detected with real-time PCR and Western blotting. Results MSCs was found homing in the rat kidney,and the glomerular size, sklerosis-rate and the average cell count of glomerulus in the treated group were different from those of the model group (P<0.05). In the treated group, the activity of SOD was significantly higher and the content of MDA was lower in serum and kidney than that in the model control group (P<0.05). The expression of VEGF mRNA and protein in the kidneys of MSCs group increased significantly as compared with the model group (P<0.05). The expression of P16 mRNA and protein in the kidney of MSCs group decreased significantly compared with the model group (P<0.05). Conclusion MSCs can increase the expression of VEGF while decrease the expression of P16, so as to play a key role in the anti-aging on rat kidney.

Objective To investigate the prevention and management of anastomotic leakage in patients with middle and lower rectal cancer after neoadjuvant therapy.Methods In this study,50 cases of middle or lower rectal carcinoma underwent anus preserving radical resection and anastomosis after a 4 cycles of chemotherapy with FOLFOX and 46 Gy(2 Gy×23)radiotherapy.Anastomotic leakage,the prevention and management of this complication were analyzed retrospectively.Results All these 50 patients received low anterior resection after chemoradiotherapy,among the 19 cases receiving prophylactic ileac stoma simultaneously,there was no anastomotic leakage,whereas anastomotic leakage developed in 4 out of the 31 patients who did not receive prophylactic ileac stoma,including concomitant rectovaginal fistula in 2 cases.All these fistulae were cured conservatively.Conclusion Concomitant treatment of FOLFOX regimen and RT in neoadjuvant setting of rectal cancer could increase the rate of anal interior sphincter reservation,prophylactic ileac stoma helps to reduce the rate of anastomotic leakage after a anus-preserving low anterior resection of the cancer.

BACKGROUND: The effect of Chinese traditional medicine 3'-meisoindigo as well as indimbin derivatives on normal immunocytes is less reported while it is used for antitumor.OBJECTIVE: To investigate the effect of 3'-meisoindigo on the proliferation of the splenocytes and thymocytes of C56BL/6 mouse.DESIGN, TIME AND SETTING: The randomized cytopathology observation was performed between August 2007 and January 2008 at Zhujiang Hospital of Southern Medical University, Guangzhou, Guangdong Province, China.MATERIALS: C57BL/6 mice, clean, male, 6-8 weeks old, weighing (20±2) g.METHODS: The thymus gland and the spleen of C57BL/6 mice were ground to get the single-cell suspension and cells were treated by 5, 10, 15, 20 and 25 μ mol/L 3'-meisoindigo,respectively. Cells without any drug treatment were used as blank control and cells treated by concanavalin A were used as positive control.MAIN OUTCOME MEASURES: Proliferation of splenocytes and thymocytes detected using MTT method; IL-12 activity in culture supematant detected using ELISA method; the cell cycle, apoptosis rate, cell death rate and intracellular reactive oxygen species level detected using flow cytometry; the mRNA level of bcl-2 and cdk2 detected using reverse transcription-polymerase chain reaction; the expression rate of Bcl-2, CDK2 and Bax detected using fluorescence microscope.RESULTS: After treating for 24 hours, 15, 20 and 25 μ mol/L 3'-meisoindigo can significantly inhibit the proliferation of thymocytes and splenocytes (P < 0.05) and the inhibition was dose-dependent and time-dependent. Cells resumed proliferation after removing the 3'-meisoindigo, although they had been treated by 25 μ mol/L 3'-meisoindigo for 72 hours. The secretion of IL-12 was markedly reduced in all 3'-meisoindigo groups versus control groups at each time point (P < 0.05). 15 μ mol/L 3'-meisoindigo could decrease the mRNA expression level of apoptosis-related protein bcl-2 and cyclin cdk2 gene, decrease the expression level of BCL-2 protein and CDK protein, increase Bax expression level, decrease Bcl-2/Bax ratio markedly and started apoptosis.15 μ mol/L 3'-meisoindigo arrested cells in the G2/M stage of the thymocytes and splenocytes, and intracellular reactive oxygen species level elevated dose-dependently and time-dependently.CONCLUSION: In certain concentration range, 3'-meisoindigo can reversibly inhibit the proliferation of thymocytes and splenocytes of C57BL/6 mouse and can inhibit IL-12 secretion in parallel, and start apoptosis.

The diagnostic evidence on clinical diseases and theoretic basis of moving cupping therapy were ex- plored in the paper. By the observation of the local reaction, such as skin appearance and color, the affected location, duration of sickness and nature of disease were judged. Different moving cupping methods were selected for different disorders. It was discovered that the property of syndromes should be recognized by the palpation on skin and muscle in the moving cupping therapy so that the pathogenesis and treating principle could be carefully determined. The moving cupping therapy is the important component of body surface therapy. Skin reaction observation and syndrome differentiation is the essential guidance of the moving cupping therapy.

Objective To evaluate the effects of exogenous adenovirus-mediated gene transfer of human apM1 gene (Ad-apM1) on malonaldehyde (MAD) and superoxide dismutase (SOD) levels in human umbilical vein endothelial cells (HUVEC). Methods HUVEC proliferation was measured by MTT after infection by AdapM1. Adiponetin protein level in cell culture medium of HUVEC cells infected with Ad-apM1 was detected by double antibody sandwich ELISA. The levels of MAD and SOD were measured by chromatometry. Results MTT assay showed that Ad-apMl had no effect on HUVEC proliferation. Human adiponectin protein levels in cell culture medium significantly increased after HUVEC was infected with Ad-apM1 for 24, 48, and 72 h, along with decreased MAD and increased SOD ( all P<0.05 ). MAD levels markedly increased and SOD levels decreased after HUVEC were incubated with 100 μmol/L H2O2 for 6, 12, and 24 h, and these reactions were reversed by AdapM1 transfection (all P<0.05 ). Conclusions HUVEC infected with Ad-apM1 effectively secrete human adiponectin. Ad-apM1 exerts antioxidation effect and antagonizes H2O2 -induced endothelial injury.
