Objective To describe our follow-up results of interventional management in 20 patients with subclavian artery stenosis. Methods This study involved in 20 symptomatic patients with an average age of 63.4 years,a mean stenose severity of 86.2% and a mean systolic arterial pressure difference of 116 mm?Hg between both upper limbs. Percutaneous transluminal angioplasty (PTA) in the first 8 patients and stenting in the last 12 patients were performed via a right femoral or radial artery. Results Both PTA and stenting were successfully archived in all patients with normalization of radial pulses and a mean systolic arterial pressure difference of 24 mm?Hg between both upper limbs. No major complications occurred. In the follow-up for an average of 18.5 months,19 patients were free of adverse events except one with symptom recurrence. Conclusion As effective,simple and safe procedures,PTA and stenting can be used as a first-line treatment modality for the symptomatic patients with subclavian artery stenosis.

ABSTRACT:Objective To study the efficacy and safety of oxcarbazepine (OXC)oral suspension on children with different kinds of epilepsy.Methods A total of 83 children with epilepsy were selected from the Pediatric Department of the First Affiliated Hospital of Xi’an Jiaotong University and Xi’an Children’Hospital from June 201 1 to June 2014.They were treated with OXC monotherapy or adjunctive therapy.Use open-label and self-contrast method.The initial dose of OXC was 8 -10 mg/(kg·d),and then was added 10 mg/(kg·d)per 7 days until it reached the minimum effective dose.Generally,the maintenance dose was about 20-40 mg/(kg·d).The follow-up duration was 6 - 12 months.Results 83 cases were eventually included and 5 cases withdrew.We elvaluated the efficacy every 3 months.The results were as follows:the first stage (1,2,3 months)resulted in a 41.0% of full control rate and a 71.8% of total effective rate;the second stage (4,5,6 months)resulted in a 46.2% of full control rate and a 76.9% of total effective rate;the third stage (7,8,9 months)resulted in a 59.0%of full control rate and a 79.5% of total effective rate.There were no significant differences in the efficacy of the three stages.54 cases with partial seizures resulted in a 59.3% of full control rate and a 79.6% of total effective
rate;24 cases with generalized seizure resulted in a 45.8% of full control rate and a 62.5% of total effective rate. There was no statistical significant difference in the efficacy of the two seizure types.43 cases with monotherapy resulted in a 58% of full control rate and a 79% of total effective rate,35 cases with add-on therapy resulted in a 40.0% of full control rate and a 57.1% of total effective rate.24 cases with < 2 resulted in a 41.7% of full control rate and a 62.5% of total effective rate,54 cases with 2-6 resulted in a 59.3% of full control rate and a 83.3% of total effective rate.14 cases of children were reported to have at least one adverse drug reactions,the specific symptoms included emotional instability unstable, hypohidrosis, somnolence, dizzness, headache, vomiting, urorrhea,lack of appetite,aggressive behavior and hypomnesia.Adverse reactions were mild and most of them could subside over time.Conclusion OXC oral suspension has a good efficacy and safety when treating children with partial seizures or generalized tonic-clonic seizures of epilepsy.

Objective To investigate the application effect of nasal gastrointestinal double lumen catheter tube placement with air insufflation in mechanically ventilated patients with intra-abdominal hypertension.Methods A total of 20 patients with intra-abdominal hypertension were randomly divided into control group and observation group (n=10 in each group).Patients in control group received indwelling nasogastric tube for decompression and indwelling nasal intestine tube by air insufflation for enteral nutrition support .Patients in observation group received the dual lumen gastrointestinal tube for decompression and enteral nutrition support.The time required for catheterization,changes in intra-abdominal pressure before and after air insufflation,catheter success rate at one attempt,pain scores of patients to catheter operation, duration of decompression,enteral nutrition start time and the duration of mechanical ventilation were compared between two groups.Results The time required for catheterization,catheter air insufflation volume in observation group were significantly lower than those in control group (P <0.01);pain scores of patients to catheter operation were significantly lower in observation group than those in control group (P <0.01);There was no significantly difference in once catheter success rate,changes in intra-abdominal pressure before and after catheterization,abdominal high pressure relief time ,enteral feeding start time, and duration of mechanical ventilation between the two groups (P >0.05 ).Conclusions The technique of air insufflation has higher success rate for Indwelling nasal intestine tube in mechanically ventilated patients with intra-abdominal hypertension,and this method is safe and reliable,dual lumen gastrointestinal tube can improve patients'comfort,shorter catheterization time and reduce catheter air insufflation volume.

Objective To investigate the effect of trimetazidine combined with atorvastatin on cardiac function and the level of hs-CRP,IL-6,and Fib in patients with coronary heart disease.Methods Patients (120 cases) with coronary heart disease in the first people's Hospital of Xianyang City from January 2014 to January 2016 were selected and randomly divided into two groups.The observation group was treated with trimetazidine combined with atorvastatin,the control group was treated with trimetazidine,the curative effect,left ventricular ejection fraction,left ventricular diastolic end systolic diameter,left ventricular posterior wall thickness and serum hs-CRP,IL-6,and Fib levels were compared.Results The effective rate of observation group was 91.67％ (55/60),significantly higher than the control group 76.67％ (46/60) (P ＜ 0.05);The left ventricular ejection fraction,left ventricular end-diastolic diameter,and left ventricular posterior wall thickness of two groups were significantly improved (P ＜ 0.05),and the improvement of the observation group was significantly better than that of control group (P ＜ 0.05);The serum levels of hs-CRP,IL-6,and Fib were significantly lower (P ＜ 0.05),and the observation group was more obvious (P ＜ 0.05);The incidence of adverse reactions of two groups had no significant difference.Conclusion Trimetazidine combined with atorvastatin have high curative effect on coronary heart disease,and can improve cardiac function,significantly reduce the levels of hs-CRP,IL-6,and Fib,worth clinical promotion.

Objective To investigate the effect of comprehensive psychological intervention on cooperation degree with intravenous infusion of preschool children. Methods 240 children patients with intravenous infusion were divided into the observation group and the control group with 120 cases in each group.Children patients in two groups were all given venipuncture by two nurses who had more than 5 years of working experience,skilled venipuncture technique and were good at doing mental work for children.The control group was given intravenous infusion directly after venipuncture without giving any psychological intervention.The observation group was given comprehensive psychological intervention before venipuncture.The different psychological behavioral reactions during the venipuncture were evaluated.The cooperation degree and the first-time success rate of venipuncture for the two groups were taken for statistics. Results The psychological behavioral reactions of the observation group were as followed:the active type was 51.67％,the tension type was 30.83％,and 7.50％ for the type of fear,the compulsive type was 10.00％.Compared with the control group,the difference was significant.The cooperation degree with intravenous infusion was 82.50％,the difference was significant compared with the control group.The first-time success rate in the observation group was 86.67％,higher than 75.83％ in the control group. Conclusions Psychological interventions according to the behavior and psychological reaction of preschool children with intravenous infusion can alleviate the negative emotions and improve the cooperation degree of preschool children.

Objective To explore the interaction of calcitonin receptor (CTR) gene polymorphisms and environmental factors in the population lived in coal-burning-borne endemic fluorosis areas in Chongqing.Methods A 1 ∶ 1 case-control study was carried out and Duping Township of Wushan County and Xinglong Township of Fengjie County of Chongqing were chosen as the endemic fluorosis areas.The observation subjects were divided into case group 121 cases and internal control group 130 cases.The Alu I polymorphism in the CTR gene was genotyped using the PCR-RFLP procedure.Logistic regression model was used to analyze the environment and genetic factors,and the interaction between genes and environment was determined according to interaction indicators.Results The rate of CC genotype in case group was lower than that of the control group [60.33％ (73/121) vs.74.62％ (97/130)],while the TT genotype was higher than that of the control group[9.09％ (11/21) vs.3.85％(5/130)].Significant differences in Alu I genotypes were observed between groups(x2 =6.57,P =0.037 ＜ 0.05; 95％CI:0.029-0.036).Allele frequencies of CTR genotypes differed significantly between groups(x2 =7.67,P =0.006 ＜ 0.01 ; OR =0.53,95 ％ CI:0.338-0.834).Urinary fluoride level (≥ 1 mg/L) was demonstrated to be a risk factor of fluorosis(OR =1.814,P =0.041 ＜ 0.05).There was a positive interaction(OR =5.530,γ =2.457) between CT + TT genotypes in CTR and the fluorosis environment of the people (urinary fluoride level ≥ 1 mg/L).Conclusions There is a certain type of interaction between CTR gene C/T polymorphism and environmental fluorine content (urinary fluoride ≥ 1 mg/L) in Chongqing population lived in coal-burning-borne fluorosis areas,and the onset of fluorosis is the result of interaction between heredity and environment.
