Objective To summarize the clinical effect of Doty procedure on surgical treatment for patients with congenital supravalvular aortic stenosis (SVAS).Methods Between Jan.2009 and Jun.2013,12 cases of consecutive patients underwent surgical corrections of SVAS using Doty procedure.Among them,Williams' syndrome were present in 5 patients.Nine cases were male,and 3 cases were female.Mean age was(5.3 ±4.2) years(9 months to 12 years) and mean weight was (11.5 ± 5.3) kg (7.5-32.0 kg).Echocardiography and Computed Tomography confirmed the diagnosis.SVAS was discrete in 9 patients and diffuse in 3 patients.Mean peak preoperative gradient was 6.86-16.23 (11.07± 3.68) kPa,with 3 patients above 13.33 kPa.Bicuspid aortic valve was present in 2 patients,mild aortic valve stenosis in 1 patient,mild aortic regurgitation in 2 patients,1 patient with subaortic membrane,3 patients with stenosis of the left or the right pulmonary artery,1 patient with pulmonary valve stenosis,2 patients with PDA,moderate to severe mitral insufficiency in 1 patients.Surgery was performed using Doty procedure through median sternotomy with cardiopulmonary bypass.Results Mean time of cardiopulmonary bypass was (85 ± 26)min (68-129 min).Mean time of aortic clamp was (51 ± 16) min(43-68 min).There was no early death and low cardiac output syndrome.Mild ST segment change was present in 5 patients and occasional premature beat was in 3 patients.Ventilator was applied for 7 to 38 h and Cardiac Intensive Care Unit treatment was done for 1 to 4 d.The mean peak supravalvular gradient measured postoperatively was (2.18 ± 1.09) kPa.Follow-up data were available for 11 patients,ranged from 6 months to 3 years.The gradients across supravalvular were lower than 3.33 kPa,except for 2 patients with severe SVAS preoperatively.There was no late death,dizzy or palpitation during follow-up.Conclusion Doty produce for SVAS can get satisfactory clinical results.

Objective To optimize the extraction process of volatile oil and inclusion preparation of hydroxypropyl-β-cyclodextrin from compoundJinling Sini Siwu Shixiaosan Granules.Methods The orthogonal approach of L9 (34) was applied to investigate the volume of volatile oil extraction by 3 factors to obtain the optimum extraction conditions. With inclusion rate of volatile oil and yield of inclusion compound as comprehensive evaluation indexes, the optimum preparation conditions were discussed. The characterization of this prepared inclusion was analyzed by TLC.Results The optimum extraction conditions were as follows:the crude medicine with medicinal powder was shattered into 20 meshes;8 times the amount of water was added and was extracted for 8 h. The best inclusion conditions were as follows:the proportion of volatile oil to HP-β-CD was 1∶6, with inclusion temperature of 30℃, grinding time of 2 h. Analysis results of TLC showed that stable inclusion compound was formed from volatile oil and HP-β-CD.Conclusion The optimized extraction process and inclusion preparation are with stable quality and high feasibility.

AIM:To analyze the characteristics of optical coherence tomography ( OCT ) in diabetic optic neuropathy ( DON ) retrospectively.
●METHODS:Retrospective study. A total of 175 cases of type ll diabetes with fundus lesions from Dec. 2013 to Dec. 2015 were selected and the clinical information was collected. These cases were diagnosed by consultation between Departments of Ophthalmology and Endocrinology in the Second Affiliated Hospital of Xi′an Jiao Tong University. The results of body examination were recorded and cases were examined by color fundus photography, fluorescein fundus angiography ( FFA) and OCT. All these data were analyzed.
●RESULTS: A total of 49 cases ( 90 eyes, 25. 7%) were diagnosed DON through FFA which manifested abnormal fluorescence in optic papilla. Results of OCT showed:among 90 eyes of DON patients, 15 eyes ( 16. 7%) had normal optic nerve form; 20 eyes(22. 2%) of excavation of optic disc became smaller or disappeared, with prelaminar tissue and peripapillary retinal nerve fiber layer (RNFL) swelling;26 eyes (28. 9%) manifested optic cup deep and cup/disc ratio increasing;18 eyes (20. 0%) had tissue hyperplasia in the hollow or on the surface of optic disc; 11 eyes(12. 3%) had symptoms including vitreous traction optic papilla and optic disc rim rising. DON eyes which had similar fluorescence features could manifest different tissue morph by OCT.
●CONCLUSION: FFA defines DON by change of blood circulation in optic nerve. However, OCT can show differences of tissue morph of optic nerve that FFA fails to do. So OCT can manifest the causes and sites of optic neuropathy more clearly and also provide basis for treatment. The advantages of OCT are conducive to reviews and curative effect tracking among DON patients and these advantages including noninvasive, convenient, inexpensive and repeatable.

Objective To investigate the effect of video -assisted thoracoscopic surgery (VATS)and conventional thoracotomy in treatment of thoracic esophagus cancer,to provide the reference for clinical.Methods 90 cases of thoracic esophageal cancer in our hospital from January 2012 to January 2015 were chosen as the research subjects.They were randomly divided into observation group(application of VATS treatment)and the control group (application of traditional open chest surgery).The quantity difference,chest drainage,hospitalization time,complica-tions,recovery conditions and other indicators of bleeding were compared in the two groups.Results The operation time of the observation group[(267.6 ±76.5)min]was shorter than that of the control group[(324.4 ±87.6)min]. The amount of intraoperative bleeding[(235.3 ±79.5)mL],drainage volume[(327.5 ±95.2)mL]of the observation group were less than the control group[(398.2 ±98.3)mL and (752.6 ±156.4)mL].Postoperative hospitalization time[(12.2 ±3.2)d]of the observation group was shorter than the control group[(15.8 ±4.4)d].The differences were statistically significant (t =3.276,8.644,15.575,4.439,all P <0.05).There were no significant differences between two groups in recurrence and metastasis rate,mortality rate and total survival rate (χ2 =0.123,0.212, 0.212,all P >0.05).The complication rate of the observation group was lower than that of the control group,the difference was statistically significant (χ2 =4.865,P <0.05).Conclusion In the treatment of thoracic esophageal carcinoma,VATS and conventional thoracotomy surgery has good effect,and VATS has small injury,less complication.

Suitable pretreatment of biological samples can truly reflect the role of law of the measured components played in the body and will provide experimental evidence for the studies on metabolic process, material basis of efficacy, mechanism of action, pharmacology, toxicology and the others. Biological samples include blood, urine, hair, tears, etc. There are also many samples processing methods, such as the direct protein precipitation, liquid-liquid extraction and solid phase extraction and so on. These methods could be used alone or combined.

In lieu of large samples of cases and/or controls with hundreds of markers spreading throughout the human genome, researchers started to notice the dramatic increase of genome-wide association study (GWAS) for complex disorders, in the last 5 years. This paper highlights the statistical challenges in such huge-scale genetic studies, and introduces the analytical strategies and steps for handling GWAS data. Such issues as quality control of data, population stratification, methods available to data analysis and results presentation, replication, as well as the limitations of GWAS studies and the challenges presenting for statistics, are addressed.
