Objective To investigate the therapy efficiency and complication prevention in patients undergoing radiofrequency current catheter ablation combined with multiple X-ray projecting angles.Methods Two hundred and six atrioventricular nodal reentrant tachycardia (AVNRT) patients were involved in this study. The distance between the tip of His and the ostium of coronary sinus were measured under different X-ray projecting angles respectively, including posterior anterior (PA), right anterior oblique 30° (RAO 30° ) and left anterior oblique 45° (LAO 45° ) in each patient, and mapping was proceeding under the corresponding X-ray projecting angles with the longest distance. The distance between ablating catheter and His was confirmed again before powering by the other two X-ray projecting angles. Results The longest distance between the tip of His and the ostium of coronary sinus were obtained in 66,75 and 65 patients under PA,RAO 30° and LAO 45° respectively(P> 0.05 ),and the data were (2.94 ± 0.87), (2.98 ± 0.76)and (2.91 ± 0.52) cm(P> 0.05). Transient first or second degree of atrioventricular blocking was observed in 4 cases among 22 high risk patients in which the powering sites were above the medium level of the distance between the tip of His and the ostium of coronary sinus under three kinds of X-ray projecting angles obviously.However,only 1 case was observed in other 184 patients(P< 0.01 ). All patients were cured successfully and no permanent atrioventricular blocking occurred. Conclusion Radiofrequency current catheter ablation combined with multiple X-ray projecting angles is helpful to increasing the successful rate and preventing complication in ablating therapy.

Objective To compare the efficacy of low temperature controlled plasma technology by nasal endoscopy and cystectomy via labiogingival groove approach in treatment of nasal vestibular cyst. Methods 38 patients with nasal vestibular cyst from Jan 2013 to Nov 2016 were selected and randomly divided into control group (n = 20) and observation group (n = 18). The control group received cystectomy via labiogingival groove approach and the observation group received low temperature controlled plasma technology by nasal endoscopy. The time of surgery, bleeding volume in surgery, hospitalization, postoperative complications and relapse were collected and compared between the two groups. Results We found that the observation group have less surgery time than that in control group [(65.45 ± 27.51) vs (34.72 ± 17.61) min, P = 0.000], less bleeding volume in surgery [(22.35 ± 18.41) vs (3.17 ± 1.69) ml, P = 0.000), less postoperative complications [(6.35 ± 0.75) vs (3.61 ± 1.19) d, P = 0.000] and less postoperative complications (16 vs 1, P = 0.000), but relapse of the two groups have no statistical difference (1 vs 0, P = 0.783). Conclusions Low temperature controlled plasma technology by nasal endoscopy in treatment of nasal vestibular cyst have many advantages than cystectomy via labiogingival groove approach such as shorter time of surgery, less bleeding volume in surgery, shorter hospitalization and less postoperative complications. Therefore it's worth of applying clinically.

Objective To understand the Oncomelania hupensis distribution and infection status in the schistosomiasis sur?veillance sites of Yunnan Province,so as to provide the evidence for making the control and prevention measures. Methods Eighteen administrative villages were selected as the surveillance sites where the schistosomiasis endemic was serious in 18 epi?demic counties,one village for one county. The snail status was investigated with the systematic sampling and environmental sampling methods,and the infection status of the snails was detected by a microscope and loop?mediated isothermal amplifica?tion(LAMP). The surveillance database was established and descriptively analyzed. Results In 2015,the total surveillance ar?ea was 1 826.55 hm2,and the area with snails was 55.03 hm2,that was reduced by 57.70% as compared to that in 2013,and by 40.63% as compared to that in 2014. No new snail area was discovered,and also no schistosome infected snails were discovered. Totally 718 532 frames were surveyed,and the occurrence rate of frames with snails was 0.45% and the density of living snails was 0.013 9 snail/0.1 m2. In the endemic controlled areas,the snail area and density of living snails were both the highest. The snails concentrated on the environments of paddy field,ditch,bottomland,small reservoir,and dry land,and the vegetations of rice,dry crop,weed and wood. The snail area,occurrence rate of frames with snails,total number of snails and number of liv?ing snails all showed a downward trend. No infected snails were found for three years. Conclusions The Oncomelania hupensis snails have been effectively controlled in the national schistosomiasis surveillance sites of Yunnan Province. However,the com?prehensive snail control measures still should be continually strengthened in order to consolidate the achivements.

Objective To provide references for enriching and innovating patterns of TCM syndrome differentiation by exploring the relationship between pathological changes and TCM syndrome differentiation of delayed graft function (DGF) after renal transplantation. Methods Totally 57 patients with DGF after renal transplantation who were diagnosed by pathological biopsy were also diagnosed by TCM doctors to obtain TCM syndromes. And the pathological diagnoses were compared with the distribution of TCM syndromes to discuss the relationship between them. Results All the patients were classified into four TCM syndromes:spleen-kidney qi deficiency, liver-kidney yin deficiency, qi-stagnation and blood stasis, and deficiency of both qi and yin. The results of pathological biopsy were as follows:acute tubular necrosis, calcineurin inhibitor toxicity and acute rejection. Quantitative corresponding relation was found between the pathological diagnoses and the TCM syndromes. Conclusion There are inner links between pathological diagnosis and TCM syndromes of DGF, which can be references for diagnosis and treatment of TCM syndrome differentiation.

Objective To investigate the relationship between refractory hypertension and renal hemodynamics in end stage renal diseases (ESRD) patients.Methods ESRD patients were classified into:patients with refractory hypertension (group A) and patients with normal blood pressure(group B).Renal hemodynamic indices were ex- amined by duplex ultrasonography.Fasting serum lipid (TC,TG,HDL-C,LDL-C,Lp(a),ox-LDL) and serum parathyroid hormane (PTH) were determined in all patients.Results Significant differences were found in renal hemodynamic indices such as peak systolic velocity (PSV),mean flow velocity (MV),pulsatility index (PI),renal- aortic ratio (RAR) and in clinical index such as Lp(a) and ox-LDL between the two group.Refractory hyperten- sion patients had lower renal hemodynamic indices and higher Lp(a) and ox-LDL levels than in patients with con- trolled BP.Logistic regression analysis revealed that refractory hypertension was related with PSV,EDV,Pl and RAR,but not relevant with sex,age,dialysis time,hematocrit,BUN,creatinine,TC,TG,HDL-C,LDL-C, PTH,MV and RI.Conclusion Atherosclerotic renal artery stenosis and severe disorder in renal hemodynamics is likely the cause for refractory hypertention in ESRD patients.The rise of serum Lp(a) and ox-LDL might acceler- ate renal artery atherosclerosis.
