Objective: To evaluate cardiopulmonary exercise testing (CPET) on sildenaifl effect for treating the patients with pulmonary arterial hypertension (PAH). Methods: A total of 25 PAH patients received sildenaifl treatment in our hospital from 2012-01 to 2014-01 were enrolled as PAH group, in addition, there were a Control group including 24 healthy subjects. The CPET, echocardiography, NYHA function class, 6-mimute walking distance (6MWD) and plasma levels of NT-proBNP at the baseline, (6-12) months and (13-18) months after sildenaifl treatment were assessed and compared between 2 groups. Results: Compared with Control group, PAH group showed decreased aerobic capacity (peakVO?2, Peak O2pulse) and ventilation efifciency (PETCO2@AT, VE?/VC?O2@AT), allP<0.05. At (8±2) months after sildenaifl treatment, aerobic capacity and ventilation efifciency was improved, meanwhile, NYHA function class, 6MWD and plasma levels of NT-proBNP were improved, allP<0.05. At (16±2) months after sildenaifl treatment, 6MWD was similar,P=0.26, while peak VO?2 and peak O2 pulse were decreased than they were at (8±2) months after sildenaifl treatment,P=0.04 and 0.06; the ventilation efifciency was elevated (as presented by increased VE?/VC?O2@AT and decreased PETCO2@AT,P=0.04 and P=0.04); plasma level of NT-proBNP was increased,P=0.05. Conclusion: CPET can effectively evaluate sildenaifl effect for treating PAH patients and therefore and guide the drugs therapy.

Objective To summarize the clinical outcomes of surgical correction of velophary geal insufficiency (VPI) with two procedures of radical intravelar veloplsties,and to discuss the indication selection of surgical technique.Methods 58 cases of various cleft palate were speech evaluated and diagnosed as mild to moderate VPI,who aged from 3 to 28 years (mean age 7.5 years).Group Ⅰ (36 cases) were performed surgery in the way of modified Furlow double-opposing Z-plasty.Group Ⅱ (22 cases) were performed surgery in the way of Sommerald radical IVV.All cases were followed up for 6 months to 1 year after surgery,with speech evaluation and objective examination of nasopharygoscopy and fixed position lateral X ray.The X-ray images of lateral view of velum was read through PACS image system.The effective work length of soft palate and the pharyngeal gap of the velum at rest and function were measured directly through PACS system.The data of each case before and after surgery were compared.Results 34 of 36 cases (94.50％) in modified-Furlow group and 21 of 22 cases (95.5％) in Sommerlad group finally recovered complete velopharyngeal closure.Compared between before and post operation,the effective work length of soft palate in modified Furlow group increased by 9.50±2.35 mm,the length in Sommerlad group increased by 7.50±3.32 mm.The differences were statistically significant by paired T test (P＜0.001).None of all cases complained nasal airway obstruction.Conclusions Both types of radical IVVs are highly effective to be recommended for surgical correction of mild to moderate VPI.Strict selection of surgical indication and excellent surgical skill are necessary for good treatment outcomes.

Objectives: To explore weather oxygen uptake efficiency slope (OUES) may predict the prognosis in patients with idiopathic pulmonary arterial hypertension (IPAH). Methods: The consecutive newly diagnosed IPAH patients in our hospital from 2010-11 to 2015-06 were prospectively enrolled and regular follow-up study was conducted to record cardiovascular events (death and lung transplantation). Kaplan–Meier curve, uni- and multivariate Cox regression analysis were performed to assess the survival rate in relevant patients. Results: A total of 210 IPAH patients at the mean age of (32±10) years were finished cardiopulmonary exercise test (CPET) and received regular follow-up study including 159 female. There were 31 patients died and 1 received lung transplantation over 41 months follow-up period. OUES was positively related to peak oxygen uptake (VO2)/body weight (r=0.71, P<0.0001). Multivariate analysis demonstrated that OUESI and NT-proBNP could independently predict the prognosis of IPAH patients. The 5-year survival rate in patients with OUESI≤0.52 L/(min?m2) was lower than those with OUESI>0.52 L/(min?m2) (41.9% vs 89.8%), P<0.0001.Conclusion: OUES as a submaximal CPET parameter may well predict the prognosis in IPAH patients.

OBJECTIVE： To investigate the correlation of ADPRT rs1136410 polymorphism with the occurrence of non-small cell lung cancer （NSCLC） in Han nationality from northern Jiangsu. METHODS： A total of 283 patients with primary NSCLC of Han nationality in Northern Jiangsu were selected from the Affiliated Hospital of Xuzhou Medical University during Nov. 2015-Dec. 2018 as NSCLC group. A total of 210 healthy subjects underwent physical examination were included in control group. PCR-RFLP was utilized to determine the genotypes at ADPRT rs1136410 locus. Logistic regression model was used to evaluate the effect of polymorphism and its interaction with smoking on the occurrence of NSCLC. RESULTS： There was no statistical significance in age and gender between 2 groups （P＞0.05）. The proportion of smoker in NSCLC group was significantly higher than control group （P＜0.05）. TT， TC and CC genotypes were detected at rs1136410 locus of ADPRT gene. The frequency of TT， TC and CC genotype were 41.9％，44.8％ and 13.3％， and those of allele T and C were 64.3％ and 35.7％ in control group. The frequency of TT， TC and CC genotype were 21.6％， 50.2％ and 28.2％， and those of allele T and C were 46.6％ and 53.4％ in NSCLC group， respectively. The frequencies of genotypes in 2 groups were in accordance with Hardy-Weinberg equilibrium （P＞0.05）， while there was significant difference in genotype and allele frequencies between 2 groups （P＜0.05）. Compared with TT genotype， the risk of NSCLC in individuals carrying TC and CC genotypes raised by 1.179， 3.122 folds [ORTC＝2.179， 95％CI （1.435， 3.309）， P＜0.05； ORCC＝4.122，95％CI（2.401，7.075），P＜0.05]. Compared with individuals carrying TT genotype， the risk of NSCLC occurrence in non-smokers carrying TC and CC genotypes increased by 0.371， 1.328 fold [ORTC＝1.371，95％CI （0.927，3.428），P＜0.05； ORCC＝2.328，95％CI （1.249，4.622），P＜0.05]； and the risk of NSCLC occurrence in smokers carrying TC and CC genotypes increased by 0.928， 2.182 folds [ORTC＝1.928，95％CI （1.257，2.957）， P＜0.05；ORCC＝3.182，95％CI （1.760，5.754）， P＜0.05]. CONCLUSIONS： The rs1136410 locus mutant genotype of ADPRT gene is the risk factor of NSCLC in Han nationality from Northern Jiangsu， and smoking raises this risk of NSCLC occurrence in individuals with mutation genotypes of ADPRT rs1136410.

External apical root resorption is among the most common risks of orthodontic treatment, and it cannot be completely avoided and predicted. Risk factors causing orthodontic root resorption can generally be divided into patient- and treatment-related factors. Root resorption that occurs during orthodontic treatment is usually detected by radiographical examination. Mild or moderate root absorption usually does no obvious harm, but close attention is required. When severe root resorption occurs, it is generally recommended to suspend the treatment for 3 months for the cementum to be restored. To unify the risk factors of orthodontic root resorption and its clinical suggestions, we summarized the theoretical knowledge and clinical experience of more than 20 authoritative experts in orthodontics and related fields in China. After discussion and summarization, this consensus was made to provide reference for orthodontic clinical practice.
