Objective To investigate feasibility, efficacy and safety of holmium laser lithotripsy under ureteroscopy to treat ureteral calculi. Methods Clinical data of 162 patients with ureteral calculi treated by holmium laser lithotripsy under ureteroscopy in our hospital from June 2006 to October 2009 were reviewed retrospectively. Stone-broken rate,lithagogue rate and complication were observed. Results The overall rate of successful fragmentation for all levels of ureteral calculi in a single procedure achieved 96. 30% (156/162). The success rates of fragmentation for the upper and mid-lower segment of ureteral calculi was 86.11% (31/36)and 99.21% (125/126),respectively. In 156 patients, the postoperative follow-up of 2- 4 weeks revealed that the stone free rate was 98.08 % (153/156). The mean operative time was (36 ± 11 )mains ( ranged from 15 to 90) and hospital stay ranged from 1 to 10 days. Conclusion Holmium laser lithotripsy under ureteroscopy is feasible,high effective and safe for the treatment of ureteral calculi, especially for those with middle or lower levels ureteral calculi.

Objective To analyze the kinds and diug resistance of bacterial.Methods 1 200 cases were detected who used the antimicrobial drugs.The drug use and drug resistance were investigated.Results 612 bacterias were isolated from the 1 200 patients,the rate was 51.0％.The top five pathogens were Pseudomonas aeruginosa,fungi,Escherichia coli,Klebsiella pneumoniae,Pseudomonas alcaligenes etc..The Cefoperazone/sulbactam and imipenem against Pseudomonas aeruginosa,Escherichia coli and Klebsiella pneumoniae had better antibacterial activity,and the cefazolin,cotrimoxazole and chloramphenicol antibacterial activity were relatively low.Conclusion The clinical use and drug resistance in different regions are unique,it should pay attention to the pathogenic examination and drug susceptibility testing,early and timely antimicrobial therapy.

Objective To observe ophthalmoscopic image characteristics of central serous chorioretinopathy (CSC).Methods Twenty-one eyes of the 18 patients diagnosed with CSC were enrolled in this study.The patients included 12 males (14 eyes) and six females (seven eyes).The patients ages ranged from 26 to 47 years,with a mean age of (39.1±5.4) years.There were nine patients (11 eyes) with acute CSC,seven patients (seven eyes) with chronic CSC,and two patients (three eyes) with recurrent CSC.All the patients were examined using color fundus photography including infrared (IR),autofluorescence (AF),near infrared ray-auto-fluorescence (NIR-AF),fluorescein angiography (FA) and indocyanine green angiography (ICGA) photography.The ophthalmoscopic image characteristics of CSC were comparared.Results The circular serous retinal detachments of 21 eyes were depicted in color images of the ocular fundus,which in the IR showed the hypo-fluorescence.Ten eyes displayed mottled hyperfluorescent spots associated with serous retinal detachments corresponding to the leakage points.The serous retinal detachments of 15 eyes in the AF images showed hypo-fluorescence,six eyes showed hyperfluorescence.Fourteen eyes presented with hypo-or hyper-fluorescent spots corresponding to the leakage points,seven eyes presented without abnormal fluorescence corresponding to the leakage points.In addition,three eyes with acute CSC showed many scattered hyper-fluorescent spots,which showed hypo-fluorescence in the ICGA.The serous retinal detachment of 15 eyes exhibited hypo-fluorescence in the NIR-AF images,six eyes showed hyper-fluorescence.Fourteen eyes presented with hypo-or hyper-fluorescent spots corresponding to the leakage points,seven eyes presented without abnormal fluorescence corresponding to the leakage points.Twenty-one eyes in FA identified the leakage.Eight eyes showed regional choroidal delayed filling,13 eyes exhibited regional choriocapillary dilatation during 1 5 minutes after injection of ICGA.During 1-5 minutes after injection of ICGA,six eyes showed more lesions than FA,three eyes showed obvious patchy hypo-fluorescence whereas the FA were normal.Conclusions CSC has its own characteristic fundus images in the IR,FA and NIR-A.FA is still the photographic method of choice,but ICGA can reveal lesions of the choroid in CSC.IR,FA and NIR-AF are not as good as FA and ICGA for detecting of leakage points.

Objective:To prepare cyclosporine A ( Cs A) microemulsion gels and investigate the quality. Methods:Cs A microe-mulsion gels were prepared, then the quality was evaluated using the physicochemical properties, particle size and distribution, content of Cs A in the microemulsion gels and rheological properties as the indices, and the stress testing and stability experiment were used to evaluate the quality as well. Results:The results showed that the physicochemical parameters were within the required ranges, the par-ticle size was uniform below 50nm, the method of determination was easy and accurate, and the rheological study revealed the gels were pseudoplastic fluid. The stress testing and stability experiment showed that the preparation could not be influenced by high temperature and highlight for 6 months at 60℃. Conclusion:The preparation is suitable for the ophthalmic use.

Objective: To explore the brain damage effects of lysophasphatidyl choline(LPC) in rats with pancreatitis and explore the pathogenesis of pancreatic encephalopathy(PE).Methods: SD rats were divided into test group,control group one and control group two at random.Acute edematous pancreatits rat model was induced following Aho HJ method for test group and control group one,then test group rats were venously applied with LPC and control group one was injected saline through tail vein.Control group two was treated with venous injection LPC through the rat tails without operation.Horseradish peroxidase(HRP) was used as a tracer to detemine if the blood-brain barrier(BBB)was open 7～10 days after successive application of LPC.The extravasated tracer was showed by diaminobenzidine(DAB).Rat brain tissue sections were examined by ponceau stain and Luxol Fast Blue stain to determine whether the rat brains were demyelination at the same time.Results: The BBB permeability of the test groupLTU rats increased greatly and obvious demyelination was observed in test group rat brains while both control groups had basically intact BBB and scarce demyelination was observed in both control groups.A statistical difference existed between the test group and control groups.Conclusion:LPC definitely open the BBB of the rat pancreatitis and demyelinates the brain of pancreatitis rats thus LPC plays an important role in the pathogenesis of PE.

Objective:To observe the curative effect and security of nicardipine combined with metoprolol succinate sustained-release tablet on renal hypertension.Method:65 renal hypertension patients were randomly divided into two groups.The patients in the nicardipine group were treated with nicardipine 80 mg q8h,while the patients in the therapy group were treated with nicardipine 40mg qd and metoprolol succinate sustained-release tablet 47.5-95mg qd for 8 weeks.Their blood pressure,heart rate,hepatic function,renal function,blood glucose and lipid were observed and recorded before and after the treatment.Result:The total efficiency was 74.4%in the controlled group and 88.5%in the therapy group,respectively. There were no obvious changes or obvious adverse reactions in their heart rate,hepatic function,renal function,blood glucose and lipid after the treatment.Conclusion:Nicardipine combined with metoprolol succinate sustained-release tablet is efficient and safe but more efficient than nicardipine alone in the treatment of renal hypertension.

The regeneration of neurons are very weak after the central nervous system is injured,the lack of growth factors in the internal environment and the existence of various inhibitors in the microenvironment are main reasons. Rho-ROCK signaling pathway mediates inhibitory signals to prevent regeneration of nerve cells in the central nervous system. In this paper,the advances in the research on biological property and regulation and interventions of Rho-ROCK signaling pathway are reviewed.
