Objective To estimate the application of ultrasound measurement of detrusor wall thickness (DWT) in the assessment of curative effect after operation. Methods Detrusor thickness was measured by linear ultrasound (7. 5 MHz) either at a filling volume of 50% of cystometric capacity or at 250 ml filling in 86 patients, who were diagnosed equivocal BOO, during a pressure-flow study. All patients accepted transurethral resection of the prostate. At 3 months post-surgery, the patients were divided into two groups according to curative effect after operation. The volume of the prostate, age and DWT were compared between the two groups. Results There was no difference in either age or volume of the prostate between the two groups. DWT was significantly higher (P＜0.01) in the more curative effect group (37 cases, DWT 2. 5±0.3 mm) compared to the less curative effect group (49 cases, 2.2±0. 3 mm). As a predictor of curative effect, DWT of 2. 8 mm or greater had a positive predictive value of 100%, a negative predictive value of 62%, specificity of 100% and sensitivity of 19%. Receiver operating characteristic analysis (ROC) revealed that DWT had a high predictive value for curative effect post-surgery with an AUC of 0. 84±0. 04. Conclusions In patients with equivocal BOO, ultrasonographically assessed detrusor thickness may have a predictive value for curative effect post-surgery. However, this cutoff value needs to be validated in a larger study population.

Objective To investigate the clinical efficacy of fractionated ultrapulse carbon dioxide laser combined with microneedle for depressed acne scars.Methods Totally 86 patients with depressed acne scar were randomly divided into 2 groups:the treatment group received fractionated ultrapulse carbon dioxide laser combined with microneedle technology and the control group only received fractionated ultrapulse carbon dioxide laser.The treatment interval was 1 to 3 months,and the whole course was 2-8 times.The total effective rate and the adverse reaction were analyzed in the facial acne scar.Results The surface of depressed acne scars was significantly improved.ECCA score of all patients declined obviously after treatment,the score of the treatment group declined from 61± 11 to 45± 15,and the control group declined from 57± 14 to 40± 16.There were significantly statistical differences in the results of each group (P＜0.05).More treatment times resulted in better surface improvement.The total effective rate were 81.8％ (18/22) and 100％ (24/24) in the treatment group,and 80.0％ (16/20) and 100％ (20/22) in the control group.The course was 6.8± 1.6 months in the treatment group and 20.8±4.6 months in the control group (P＜0.05) to get a similar satisfied result.There were no obvious adverse reactions except two cases of erythema and pigmentation in the treatment group and 5 cases in the control group.The former was with less adverse reactions.Conclusions Ultrapulse carbon dioxide laser combined with microneedle technique is effective for facial acne scars,with less complications and shorten treatment course.

Objective To investigate the clinical efficacy of Q-switch 1064 nm wavelength laser combining with microneedle technology for the treatment of melasma.Methods 70 melasma patients were selected in the Out-patient Department of Wuhan General Hospital of Guangzhou Military Command from July 2012 to Sept.2013.The patients were randomly divided into 3 groups:the combining therapy group (patients in this group received Q-switch 1064 nm wavelength laser combining with microneedles technology,the treatment interval was 2 or 3 weeks,and the whole course was 2-6 months);the microneedle group and the Q-switch 1064 nm wavelength laser group.The effect and the adverse reaction were observed and recorded during the treatment,and the reduced area of the pigment patch was also measured to judge the total efficacy after the course.Results The total effective rate was 78.6％ (22/28) in the combining therapy group and 40.0％ (8/20) in the microneedle group,45.5％ (10/22) in the Q-switch 1064 nm wavelength laser group.There were statistically significant differences between the combining therapy group and the other groups (P1 ＜0.05,P2 ＜0.05),without obvious adverse reaction.Conclusions It is significantly better to use American Medlite C6 Q-switch 1064 nm wavelength laser combining with microneedles technology than that of the single use of Q-switch 1064 nm wavelength laser or microneedles in the treatment for the patients with melasma.The method is also simple to handle and suitable for clinical application.

Objective To evaluate the choice of therapeutic methods and MRI diagnosis of acoustic neuroma.Methods The MRIimaging and clinical materials of 60 patients with acoustic neuroma were analyzed,48 cases were underwent an operation,12 cases weretreated conservatively or gamma knife treatment,follow-up ranged from 1 to 4 years.Results There were 62 tumors round the internalauditory canal.There were 58 cases with single acoustic neuroma and two cases with couples acoustic neuroma.28 tumors demonstratedhypointense and 30 tumors demonstrated hypo-and isointense signals on T_1 weighted image.38 tumors demonstrated hyperintense and 24tumors demonstrated hyper-and isointense signals on T_2 weighted image.The Ⅶ,Ⅷ nerves affected side were thickened than that ofopposite side in 32 patients.After Gd-DTPA administration 24 tumors were homogeneously enhanced,26 tumors were inhomogeneously or circularly enhanced in 50 acoustic neuromas of 48 cases.Operation was still the main election for acoustic neuroma.Conclusion MRI is an effective method in the diagnosis of acoustic neuroma,and providing advice for clinics in making therapeutic programs.

Objective:To explore the involvement of endoplasmic reticulum molecular chaperone GRP78 in the impairment of inner ear consistented with the mimetic aging model.Method:Twenty-four Wistar rats were randomly divided into two groups. model group was in duced by daily hypodermic injection of 10% D-galactose (800 mg·kg~(-1)·d~(-1)) for 8 weeks and the control group was given saline accordingly. Spatial learning and memory was measured by Morris-Water-Maze. Colorimetry was used to analyze superoxide dismutase (SOD) and malondialdehyde (MDA) extracted from inner ear tissue. Hearing threshold of rats were detected with Auditory brainstem response (ABR).In addition, expression of GRP78 in the inner ear was detected by immunohistochemistry,RT-PCR and Western blot. The control group was studied parallel.Result:The escape latency in the model group injected with D-galactose was markedly longer than that in the control group.accordingly ,the changes of SOD and MDA were more significant in the model group, the difference between two groups was significant(t-test,P<0.01). the variation of ABR in two groups was observed, There was no statistically difference of the hearing in the model group compared with the control group(P>0.05). The expression of GRP78 was significantly different between two groups ,which is increased in the inner ear tissue of model group(P<0.01).Conclusion:The impairment of inner ear tissue partly dued to the oxidative stress in the model, which was induced by D-galactose.and endoplasmic reticulum molecular chaperone was thought to contribute to the impairment mechanism of inner ear in mimetic aging model.

Objective To study the repairing effects of nerve growth granule(NGG) on rat common peroneal nerve transection injury.Methods After 50 Sprague-Dawley rats were subjected to nerve suture after transaction,they were randomly divided into 5 groups for daily intragastric administration of drugs:NGG high-dose(5.2g/kg),medium-dose(2.6g/kg),low-dose(1.3g/kg) groups,mecobalamin group(positive control) at 625 ?g/kg,control group(control group control).The drug administration lasted for 4 weeks.Footprint test was performed 2-,3-and 4-weeks after surgery to evaluate toe spread function(TSF).Electrophysiology was performed 4 weeks after operation to determine the compound muscle action potential(CMAP) and nerve action potential(NAP).The number of regenerated myelinated nerve fibers,thickness of myelin sheath and cross sectional area of tibial muscle were measured by histomorphology.Results TSF,amplitude and recovery rate of CMAP and NAP,the number of regenerated myelinated nerve fibers,thickness of myelin sheath and section area of tibial muscle were all increased significantly in a dose-dependent manner compared with the control group.Conclusion NGG contributes to axon growth and myelination,and thus promotes peripheral nerve regeneration in rats with functional recovery.

In light of modern management theories and the actual situation in the hospital, a post and performance based hospital compensation system was designed. The chief features of the design include: ① Compensation consists mainly of post salary and performance salary while giving expression to the principle of stability and gradual transition, with the fixed part (accounting for about 60%) of the original file salary being retained; ②Post salaries fall under a hospital wide unified grade compensation framework, with grade evaluations based on a hospital wide unified system of indexes and weight, and they go up or down within the salary width each year according to the results of performance assessment; ③ Performance salaries are closely linked with post grades and performance assessment, with a hospital wide unified model of post and performance contracts being the basis for assessment; ④ The entire compensation design is based on scientific and standard post surveys, post appraisals and post specifications.
