AIM: To study the dynamic changes of free radicals and antioxidative system of prostate in rats with short-term diabetes. METHODS: 48 Wistar male rats were divided into 6 groups at random (8 rats in each group). One group were injected(ip) with sodium citrate buffer to be the control group, the other 5 groups were injected (ip) with steptozocin(STZ) 60mg/kg body weight which were called diabetes group. Rats were killed after 1, 3, 5, 7 and 14 days; superoxide dismutase(SOD), malondialdehyde(MDA), glutathione(GST), glutathione s-transferase(GST), glutathione peroxidase(GSH-px), nitric oxide (NO) and nitric oxide synthase(NOS) of prostate were examined. RESULTS: The levels of MDA, GSH-px and NO in prostate homogenate of diabetes group were higher evidently as compared with control levels. The activities of SOD, GST, NOS and the levels of GSH in prostate homogenate were increased obviously after injection of STZ with control levels, then returned near to control values. CONCLUSION: The evidences mentioned above indicate that high-level of free radicals and decrease in antioxidative system rendere the prostate cells to be in oxidative stress.

Objective To evaluate the safety and efficacy of Holmium laser resection for primary non-muscle invasive bladder cancer (HoLRBt) compared with transurethral resection of bladder tumor (TURBt). Methods Data of 212 patients with primary non-muscle invasive bladder cancer were collected retrospectively. The patients were divided into HoLRBt group(n= 101) and TURBt group (n= 111). The patients in each group were stratified into 3 risk groups (low, intermediate and high risk) according to prognostic factors for recurrence based on EAU guideline. Then, the safety of HoLRBt and TURBt groups were compared, concerning the intraoperative complications and postoperative recovery. Efficacy indicated by recurrence-free survival of the 2 groups was analyzed and compared by Kaplan-Meier technique. Results Patients' demographics including age, gender, tumor characteristics, and recurrence risk of tumor between the 2 groups were comparable(P＞0.05). No obturator nerve reflex occurred in the HoLRBt group. Meanwhile, 7 out of 111 patients in the TURBt group experienced this complication resulted bladder perforation in 3 patients. The proportion of patients needing postoperative bladder irrigation in the HoLRBt group was lower compared to the TURBt group (P＜0.05). HoLRBt was associated with shorter postoperative catheter drainage period (P＜0.05). The mean postoperative follow-up was 34 months (range 18 to 43). Recurrence-free survival after HoLRBt was similar with that of TURBt (P = 0. 283). Conclusions Compared with TURBt, HoLRBt is a feasible, safe and effective alternative for the management of primary non-muscle invasive bladder cancer with similar therapeutic efficacy and fewer perioperative complications.HoLRBt can be widely used in clinical practice in the treatment of primary non-muscle invasive bladder cancer.

The cyclodialysis cleft is a rare disease characterized by ocular hypotony and vision loss.Gonioscopy,ultrasound biomicroscopy and anterior segment optical coherence tomography are used to evaluate the cleft before treatment.The evaluation of cyclodialysis clefts provide a basis for the selection of treatment and the evaluation of effect.Current popular therapeutic approaches for cyclodialysis clefts include medical management,laser photocoagulation,transscleral diathermy,cryotherapy,cyclopexy and so on.Medical treatment is effective in small-size cyclodialysis cleft.But the indications and course of medical treatment remains controversial.Although laser photocoagulation,transscleral diathermy and cryotherapy are effective to treat cyclodialysis clefts in some cases,there are some risks,such as ocular damage,uncertainty about the effect and so on.Cyclopexy is the principal method for cyclodialysis clefts that failed to respond to conservative management,including extraocular cyclopexy,intraocular cyclopexy and cyclopexy under endoscopic.The modified cyclopexy is effective which reduces the surgical risk.For keeping the lens,intraocular cyclopexy and cyclopexy under endoscopic are not suitable.Vitrectomy combined with other method for cyclodialysis is effective for cyclodialysis clefts which combined with serious posterior segment damage.

Objective To evaluate the values of continuous subcutaneous insulin/rapid insulin analoguc infusion in desensitization for allergy to recombinant human insulin. Methods Two patients allergic to recombinant human insulin received desensitization therapy by continuous subcutaneous insulin lispro infusion. The diluted insulin lispro solution was pumped with initial basal rate of O. O1 U/h, and the basal rate and insulin lispro concentration increased gradually until the insulin dosage for clinical treatment was reached. After that, continuous subcutaneous insulin lispro infusion was replaced by regimen of insulin lispro subcutaneous injection plus oral hypoglycemic agents. Results Local wheals were not observed in both two patients during continuous subcutaneous insulin lispro infusion or during bolus subcutaneous injection of insulin lispro after desensitization. Conclusion The desensitization therapy by continuous subcutaneous insulin/rapid insulin analogue infusion can be applied for allergy to recombinant human insulin.

This study was aimed to establish the TLC identification method of Radix Mirab ilis himalaic a. The β-sitosterol and daucosterol were used as the reference substances. The single-factor test was used. A variety of factors which affected TLC were systematically investigated to filter out the best TLC conditions for identification of different batches of medicines. The results showed that the best TLC conditions were as follows: silica gel G plates, extraction solvent (methanol), reagent (5% sulfuric acid in ethanol), extraction method (ultrasonic extraction with methanol), ex-tracted time (30 min), the agent (petroleum ether-ethyl acetate-acetone (5:2:1)) and sample volume (6 μL). It was concluded that the method, which had high separation degree, was reproducible and simple. It can be used as the quality control of Radix Mirab ilis himalaic a.
