Objective To analyze the application effect and safety of streamlined liner of the pharynx airway (SLIPA) anesthesia in painless fiberoptic bronchoscopy (FB).Methods Two hundred and eighty-two patients who undorwent FB examination in Kaifeng Second People's Hospital from January 2015 to January 2017 were selected and divided into observation group and control group,with 141 patients in each group.The patients in observation group were given SLIPA assisted anesthesia;the patients in control group were given endoscopic mask assisted anesthesia.The oxygen saturation (SpO2),systolic blood pressure (SBP),diastolic pressure (DBP) and heart rate (HR) of patients in the two groups were monitored.The changes of SBP,DBP and HR,the incidence of adverse reactions and the satisfaction of patient to the anesthesia were compared between the two groups.Results The fluctuation of HR,SBP and DBP of patients in the observation group was (3.52 ± 2.92) times · min-1,(7.04 ±5.30) mmHg(1 mmHg =0.133 kPa),(1.52 ± 1.63) mmHg respectively and in the control group was (5.52 ± 1.89) times · min-1,(30.12 ± 8.88) mmHg,(4.06 ± 5.78) mmHg respectively;the fluctuations of HR,SBP and DBP of patients in the observation group were significantly less than those in the control group(P ＜ 0.05).In the observation group,12 patients with cough,8 patients with abdominal distension,6 patients with pharyngeal pain,2 patients with SpO2 ≤90％,4 patients with SpO2 ＜ 85％;in the control group,57 patients with cough,32 patients with abdominal distension,47 patients with pharyngeal pain,28 patients with SpO2 ≤90％,19 patients with SpO2 ＜ 85％.The incidence of adverse reactions of patients in the observation group was significantly lower than that in the control group (x2 =27.10,61.82,41.59,72.46,87.75;P ＜0.05).The anesthesia satisfaction of patients in the observation group(97.87％) was significantly higher than that in the control group(82.98％) (x2 =29.97,P ＜ 0.05).Conclusion SLIPA assisted anesthesia has good clinical effect and safety in patients with painless FB.

Objective To evaluate the clinical usefulness of MR imaging(MRI) and MR tomography angiography(MRTA) in demonstrating the presence and degree of neurovascular contact of the rostral ventrolateral medulla oblongata(RVLM) in root entry zone of the 9th and 10th cranial nerves in patients with essential hypertension(EHT) and normotensive health volunteers(NTHV).Methods(Patients with) EHT(group 1,n=100) and NTHV(group 2,n=88) underwent high-resolution(axial and coronal) brain stem MRI and MRTA.Images were interpreted consensually by tow radiologists who were blinded to the patients hypertensive status.Neurovascular contact was graded as vessel contact without RVLM deformity(gradeⅠ),clear vessel contact in continuity with the brain stem but without apparent associated deformity(graded Ⅱ), and displacement contact of the RVLM(graded Ⅲ).Results(Neurovascular) contact of RVLM was found in 52.0%(52/100) of EHT and in 43.2%(38/88) of NTHV(?~2=1.459,P=0.230).The compression rate(gradeⅠ—Ⅲ) and affected side(left or right) showed no statistically significant differences between the EHT and NTHV(?~2=0.879,P=0.350;?~2=0.238,(P=0.628);?~2=0.733,P=0.390).Conclusion Neurovascular contact is not more frequently seen in patients with EHT than in normotensive contact subject.This result does no support the hypothesis that neurovascular contact at the RVLM is an etiology of EHT.Furthermore,thin-slice(3 mm) MRI may not be a reliable good screening method for detecting patients with neurovascular contact.Therefore,MRI cannot aid patient selection among hypertension patients lacking symptomatic cranial neuralgias.

OBJECTIVETo explore the distribution features of Chinese medical constitutions in different ages population, thus providing scientific evidence of constitution process theory.

METHODSRecruited were 21 948 cases from a survey of Chinese medical constitutions and health conditions in 9 provinces or municipalities across China (including Jiangsu, Anhui, Gansu, Qinghai, Fujian, Beijing, Jilin, Jiangxi, and Henan) from Dec 2005 to Jan 2007. The body constitution type of individual was diagnosed using discriminant analysis on the basis of Chinese medical constitution questionnaire. By using correspondence analysis, the correlation between the general population, genders, ages, and Chinese medical constitution types was studied.

RESULTSConstitutions of yin-deficiency type, wetness-heat type, qi-depression type, and special diathesis type often occurred in the population ranging 15 -24 years old. Gentleness type mostly occurred in the population ranging 25 -44 years old. During this time period, phlegm-wetness type and wetness-heat type were liable to occur in males, while blood-stasis type was liable to occur in females. Qi-deficiency type and yang-deficiency type were most often seen in those older than 45 years. Phlegm-wetness type and blood-stasis type body constitution were also liable to occur in those older than 45 years.

CONCLUSIONSThe distribution features were different in different Chinese medical constitutions. Different constitution types exist in different genders. Different constitution types exist different ages population.

Objective To analyze the potential etiologies and risk factors of childhood stroke. Methods This study retrospectively reviewed the clinical data of 159 children who were admitted from Jan.2006 to Jan.2014. Results The 159 children were composed of 100 boys and 59 girls , with median onset age of 1.8 years (ranged from 1 day to 12 years old) and median peak age of 0.9 years (ranged from 3 months to 2.8 years old). Their initial symptoms included limb hemiplegia,language dififculties and convulsion. The common causes included infections found in 46 cases (central nervous system infection in 32 cases, respiratory and gastrointestinal tract infection in 14 case), head injury in 42 cases, vitamin K deifciency in 29 cases, Moyamoya disease in 8 cases, heart diseases in 11 cases, spontaneous hemorrhage in 11 cases and 12 cases of unknown reason. Infectious diseases were the most common cause of children acute ischemic stroke in toddler period;and vitamin K1 deifciency were the most common cause of children hemorrhage stroke in infancy. The most common region of infarction is basal ganglia and middle cerebral artery in neuronal imaging. The median age at the time of diagnosis was 1.4 days. The median time of inhospital was 28 days. The median apex time was 4.3 days. Conclusions Among 159 cases, acute ischemic stroke is much more common than hemorrhagic stroke in children stroke, and the major risk factors are infections and head injury;Vitamin K1 deifciency is a major risk factor in infants with hemorrhagic stroke.

Objective To study the effect of leaf movement speed on the setup error of multileaf collimator (MLC) in RapidArc mode,and to improve quality assurance and verify the reliability of RapidArc.Methods Referring to the PicketFenceStatic_M120.dcm and PicketFenceRA_Ml20.dcm files,the Tilt tests with different adjacent leaf speed were designed and setup errors of MLC were obtained by analyzing electronic portal imaging device images.Results In the Tilt tests,the setup errors gradually increased from gapl 1 to gapS0 in both static gantry mode and RapidArc mode.With a gantry angle of 270°,gap41 had the maximum setup error of-0.55 mm.In the RapidArc mode,gap46 had the maximum setup error of-0.67 mm.The deviation of gap width was no greater than 15％ in any mode.There was no significant difference in deviation pattern of gap width between four modes with different gantry angles.The same gaps in different stripes showed a consistent trend in gap width.The RapidArc mode had a larger variation in percentage deviation of gap width than the static gantry mode.Conclusions The setup error increases with the increase in the speed of MLC leaf.The variation in the leaf speed has no significant impact on the gap width.There is no correlation between the leaf speed and the deviation of gap width.Four different gantry angles give similar deviation patterns of gap width,suggesting that the deviation of gap width is related to the leaf rather than the gantry angle.The RapidArc mode has a greater impact on the gap width than the fixed gantry mode.
