[ABSTRACT]OBJECTIVETo assess the efficacy of postauricular injection of shuxuening combined with lidocaine in treating intermediate and high-frequency sudden hearing loss.METHODS48 patients with intermediate and high-frequency sudden hearing loss were randomly divided into postaurical injection group (n=24) and control group (n=24). The control group was given hormone, microcirculation improvement, nutrition of nerve and other conventional treatment. The postauricular injection group received 3 doses of postauricular inject of 0.5ml shuxuening and 0.3ml lidocaine tertian injection in addition to conventional treatments.RESULTSTwo weeks after administration, the total effective rates of postauricular injection group 87.5%were significantly higher than that of the control group 62.5%. Pure tone average improved (20.74±15.19)dB on average in the postauricular group, and (12.44±9.12)dB in the control group. The difference was statistically significant (P<0.05). CONCLUSIONPostauricular injection of shuxuening combined with lidocaine treatment for intermediate and high-frequency sudden hearing loss has better curative effect than that of the conventional treatment.

Objective To investigate the effect of ethanol using by neurolytic celiac plexus block(NCPB)on the Bispectral index(BIS)during anaesthesia with propofol and remifentanil.Methods Thirty-six patients,ASA Ⅰ～Ⅲ,undergoing pancreatic cancer surgery were studied.Patients were maintained with propofol(6～9mg·kg～·h-1)and remifentanil(0.1～0.3μg·kg～·min-1)to keep the BIS between 38 and 50.After 30minutes of stable anesthesia,patients in control group were treated with NCPB by 0.9%NS 30ml,while patients in ethanol group were employed NCPB at the same time by 75%ethanol 30m1.BIS values,mean arterial pressure(MAP),heart rate(HR)were recorded 5minutes before the injection and one,five,fifteen,twenty five,thirty five,forty five minutes after that.Results Therewas no significant change in BIS,emodynamic variables compared to preinjection values in the control group.15min to 45min after injection of four point,BIS values and MAP of ethanol group decreased significantly,as compared with before injection,the same time point compared with the control group had statistically significant difference(P＜0.001).No significant changes in HR were observed throughout the observation.Conclusion Ethanol used in the operation of NCPB was additive to the anesthesia depth during the anesthesia of propofol and remifentanil.

Objective To design a hemostatic clip and evaluate its efficacy and success rate of closure of stomach wall defect after full thickness resection (FTR).Methods A full thickness circular or linear resection (3 to 5 cm) was made on each model's antrum with needle knife and insulated-tip knife.The specimens were divided into 2 groups, using either an interrupted or continuous suturing method.Then the closure condition, suturing time, number of clips required and success rate of closure were compared.Results All 12 defects were successfully closed.The average closing time of interrupted and continuous suturing group were 13.33 ± 1.09 and 10.17 ±2.11 minutes, and the mean number of clips used were 4.67 ± 0.82 and 2.67 ± 0.82.The success rate was 100％.Conclusion This newly designed clip is a fast, reliable and convenient tool for stomach wall defect closure after FTR.

Background In patients with syphilis,one of the common manifestations is uveitis.However,the lack of understanding on syphilic posterior uveitis may result in misdiagnosis and delayed treatment.Objective This study was to assess ocular clinical features,treatment and prognosis in patients who had latent syphilis and presented with posterior uveitis as the initial symptom.Methods A serial cases-observational study was designed.Twelve patients(19 eyes)who were diagnosed as syphilis from September 2011 to January 2013 were retrospectively analyzed.All patients were characterized by initial posterior uveitis before the final diagnosis.The clinical manifestation,management and prognosis were evaluated and analyzed.All patients were informed of this study and consented with the use of their data for this retrospective study.Results The patients presented with initial clinical signs of acute or chronic posterior uveitis and lacked systemic syphilis symptom.Bilateral posterior uveitis were found in 7 patients and unilateral in 5 patients.The dust-like and grey-white opacification in vitreous was seen by threemirror contact lens in all the patients.Mild hyperemia of the optical disc was found in 10 eyes with the unclear peripapillary boundary.Yellow-white lesions were observed in retinas of 7 eyes and retinal punctuate hemorrhage was in 1 eye.Fundus fluorescein angiography demonstrated fluorescine staining or hyperfluorescence of optic disc in all of the 19 eyes,and fluorescein leakage from vein in 18 eyes,retinal pigment epithelium dye pooling in 6 eyes and cystoid macular edema in 11 eyes.Rapid plasma reagin (RPR) test and treponema pallidum hemagglutination assay (TPHA) were performed and presented positive results in all patients.The visual acuity improved in 19 eyes and partly elevated in 2 eyes following a standard therapy for neurosyphilis was used,including penicillin and/or small doses of glucocorticoid.Conclusions The serological examination for syphilis should be considered for patients with unexplained uveitis.Early diagnosis and prompt treatment are important for the improvement of prognosis in syphilitic posterior uveitis.

OBJECTIVETo observe the therapeutic effect and relevant mechanism of shuxuening Injection (SI) in treating patients with active ulcerative colitis (UC).

METHODSTotally 91 patients with active UC were randomly assigned to 2 groups, 44 in the control group and 47 in the treatment group. Patients in the control group received routine treatment, while patients in the treatment group additionally received intravenous injection of SI (15 mL), twice daily for 14 days in total. Colonoscopy was performed before and after treatment. The therapeutic effect was assessed by Mayo scoring system and the grading of activities evaluated by Baron endoscope. Serum levels of IL-6 and TNF-α were detected by ELISA. The activity of SOD was detected by xanthine oxidase method. The content of MDA was detected by thiobarbituricacid (TBA). Besides, 20 healthy subjects were recruited as the healthy control group.

RESULTSTotally 82 patients completed the study (40 in the control group and 42 in the treatment group). There was no statistical difference in serum levels of IL-6, TNF-α, SOD, MDA, the Mayo score and endoscope grading between the two groups before treatment (P >0. 05). Compared with the healthy control group, serum levels of IL-6, TNF-α, MDA significantly increased (P <0.01), and the serum SOD level decreased (P < 0. 05) in the treatment grup and the control group before treatment. Compared with before treatment in the same group, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased in the treatment group and the control group after treatment (P <0. 01, P <0. 05). Compared with the control group after treatment, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased (P <0.01, P <0.05), the serum SOD level increased (P <0.05) in the treatment group after treatment. The serum SOD level was obviously negative correlated with serum levels of IL-6, TNF-a, Mayo score, and endoscope score (r = -0. 621, -0.638, -0. 509, -0.787, P <0.01). The serum MDA level was obviously positive correlated with serum levels of IL-6, TNF-α, Mayo score, and endoscope score (r =0.711, 0. 882, 0. 525, 0. 639, P <0.01).

CONCLUSIONSI could improve inflammatory injury and clinical symptoms of patients with active UC, and its mechanism might be associated with antioxidant and scavenging oxygen free radicals.
