Objective To explore the safety and clinical efficacy of radical transurethral photoselective vaporization of bladder tumours (RPVBT) combined with chemotherapy in the treatment of muscle invasive bladder cancer.Methods Collected during Sept.2010 to Sept.2012,a total of 34 patients with muscle invasive bladder cancer who refuse or older,merge the heavier medical disease,difficult to tolerate radical cystectomy.Using RPVBT,vaporization resection to the bladder wall fat layer,postoperatively systemic chemotherapy of gemcitabine combined cisplatin and bladder perfusion chemotherapy of pharmorubicin.The operation time、the first recurrent time and recurrent rate,and the survival rate were measured.Results Operation are completed smoothly,operating time is 30.5-69.0 min and average 49.2 min,intraoperative rinses quantity is 5.9-10.7 L and average 8.3 L.Intraoperative no obvious bleeding,intraoperative no serioue complications,postoperative pathological diagnosis is invasive epithelial cell carcinoma of the urinary tract,pathology classification:low level 15cases,the high level 19 cases.Followup of 12 to 36 months,an average of 21 months,9 cases of recurrence,2 cases underwent radical cystectomy,7 cases again RPVBT,the first tumor recurrence time 3-20 months,11 months and the median time to relapse recurrence rate 26.5％ (9/34),3 cases of relapses diedof bladder cancer metastasis,31 cases of survival.Conclusion Treatment of RPVBT combination chemotherapy in patients with locally invasive bladder cancer,small trauma,less bleeding,high safety,have certain curative effect,It could be a effective treatment strategy for patients of high-risk elderly or unwilling to accept Radadical cystectomy.

Objective To explore the protective effect of co-treatment with antioxidants 4-hydroxy-2,2,6,6-tetra-methylpiperidine 1-oxyl (TEMPOL) and reduced glutathione (GSH) in pancreatic injury induced by intermittent hypoxia (IH) in mice. Methods Fifty male C57BL/6J mice were randomly divided into control group(CON), IH group (IH), IH+TEM-POL group (IH+TEMPOL), IH+GSH group (IH+GSH) and IH+TEMPOL+GSH group (IH+TEMPOL+GSH). After successful-ly prepared animal model, the insulin resistance (IR) level, pancreatic malondialdehyde (MDA) level,superoxide dismutase (SOD) activity,glutathione reductase (GR) concentration and pancreatic β-cell apoptosis were detected in five groups. Re-sults The blood glucose level was significantly increased in IH group than that in CON group (P<0.01), but which was sig-nificantly decreased in IH+TEMPOL+GSH group than that of IH group (P<0.01). The MDA content was significantly higher in the IH group than that in CON group (4.48±0.25 vs 1.94±0.21, P<0.01), but SOD activity and GR content were signifi-cantly lower in IH group than those of CON group (61.52±3.33 vs 100.05± 7.26,107.81±7.54 vs 170.54±4.90,P<0.01). The level of MDA was significantly lower in IH+TEMPOL+GSH group (2.07±0.35) than that in IH group. The levels of SOD and GR were significantly higher in IH+TEMPOL+GSH group (96.68±5.85 and 166.87±5.75) than those of IH group (P<0.01). The apoptotic rate of pancreaticβcells was significantly increased in IH group than that in CON group (2.43±0.07 vs 0.54± 0.06, P<0.01), but it was significantly lower in IH+TEMPOL+GSH group (0.56 ± 0.06) than that in IH group (P<0.01). There were no significantly differences in all above indexes between IH group, IH+TEMPOL group and IH+GSH group ( P>0.05). Conclusion The co-treatment with the antioxidant TEMPOL and GSH can obviously protect IH-induced pancreatic injury in mice. However, there was no significant protective effect of TEMPOL or GSH alone on pancreatic injury.

The carotene content of 63 kinds of plant materials including vegetables, grasses, wild plants and tree leaves were determined by the column chromatography method. Alfalfa, shepherd purse and carrot had the highest carotene content among the tested plants.Four methods were tried for the preparation of carotene concentrates. It was found that percolation with ethyl ether after grinding in ethanol showed the highest yield at low cost.The carotene content of the above mentioned concentrates was almost completely destroyed after 4 months when stored at room temperature and exposed to light. There was appreciable loss of the vitamin after 5 months' storage in the dark at low temperature (below 6℃), however, the loss was much smaller than that stored at room temperature. The loss of carotene was greatly reduced when the carotene concentrates were stored under nitrogen either at low temperature or at room temperature compared with those stored in the air. The addition of heated soy-bean meal to the carotene concentrate also considerably reduced the carotene loss during storage at room temperature.
