Objective To observe the outcomes of intranasal endoscopic holmium laser-assisted dacryocystorhinostomy in the treatment of chronic dacryocystitis. Methods Forty-seven patients(47 eyes) with chronic dacryocystitis underwent intranasal endoscopic holmium laser-assisted dacryocystorhinostomy.The postoperative follow-up included lacrimal irrigation and intranasal endoscopic examination. Results The patients were followed up for 3 to 6 months.The cure rate was 87.2%,the improvement rate was 6.4%,and the total effective rate(cure rate+improvement rate) was 93.6%.Conclusion Intranasal endoscopic holmium laser-assisted dacryocystorhinostomy causes no scar in the face,less nasal tissue damage,shorter operation time and less hemorrhage,and does not affect the lacrimal irrigation system,which allows correction of intranasal causes of failure in traditional dacryocystorhinostomy.

Objective To search the relationship among blood pressure,blood lipid and fat liver in childrcn with simple obesity.Methods Blood pressure,blood lipid and ultrasound of liver of 40 cases with simple obesity and 20 cases in normal control had been detected.Results there were 11 cases without complication in children with simple obesity,the simple obesity with hypertension complication were 14 cases,and the simple obesity with high blood lipid were 15 cases.The level of total cholestrrol(TC),triglyceride(TG),light density lipoprotein(LDL)and very light density lipoprotein(VLDL)in obesity children were significantly higher than those of control group(P

Objective To investigate the characteristic of ?-amyloid precursor protein (A?) processing in activated platelet in AD.Methods Thirty-six sporadic AD patients and 30 control subjects were included in this study.Blood was collected from the subjects to separate platelets.After treated by thrombin,the soluble amyloid precursor protein (APP) level in the snpernatants of platelets from 36 were analyzed by means of western blot with a specific antibody recognizing soluble APP.Meanwhile A? level was measured by radioimmunoassay.Results After treated with thrombin,the level of soluble APP in the supernatants of platelets in patients with AD decreased by 31.0% (P

Background:The symptomatic bradyarrhythmia is Class Ⅰ indication for pacing therapy which is not a radical cure.The present study aimed to assess the feasibility and to present the initial results of the restricted ablation of the parasympathetic innervation surrounding sinus and atrioventricular (AV) nodes for treating patients with bradyarrhythmia.Methods:A total of 13 patients with cardiogenic syncope were included from May 2008 to June 2015.Under the guidance of fluoroscopy and/or three-dimensional geometry by 64-slice spiral computed tomography,atrial activation sequence in sinus rhythm was mapped.Chamber geometry was reconstructed manually or automatically using the Niobe Ⅱ magnetic navigation system integrated with the CARTO-remote magnetic technology (RMT) system.Cardioneuroablation was targeted at the high-amplitude fractionated electrograms surrounding the regions of His bundle and the site with the earliest activation in sinus rhythm.Areas surrounding the sinus node,AV node,and the phrenic nerve were avoided.Results:Thirteen patients completed the studies.Ablation was successfully performed in 12 patients and failed in one.The high-frequency potential was recorded in atrial electrograms surrounding the sinus or AV nodes in all the patients and disappeared in 15 s after radiofrequency applications.The vagal reaction was observed before the improvement of the sinus and AV node function.No complications occurred during the procedures.Patients were followed up for a mean of 13.0 ± 5.9 months.During the follow up ten patients remained free of symptoms,and two patients had a permanent cardiac pacemaker implanted due to spontaneous recurrence of syncope.The heart rate of post-ablation was higher than pre-ablation (69.0 ± 11.0 vs.49.0 ± 10.0 beats/min,t =4.56,P =0.008).The sinus node recovery time,Wenckebach block point,and atrium-His bundle interval were significantly shorter after ablation (1386.0±165.0 vs.921.0 ±64.0ms,t=7.45,P=0.002;590.0±96.0 vs.464.0± 39.0ms,t=2.38,P=0.023;106.0±5.0 vs.90.0 ± 12.0 ms,t =9.80,P =0.013 before and after ablation procedure,respectively).Conclusions:Ablation of sinoatrial and AV nodal peripheral fibrillar myocardium electrical activity might provide a new treatment to ameliorate paroxysmal sinus node dysfunction,high degree AV block,and vagal-mediated syncope.
