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.

BACKGROUND: Recently, Chinese herb and comprehensive therapy are widely adopted for the treatment of chronic atrophic gastritis (CAG), while infrared ray is widely used in the fields of physical therapy and scientific research. Therefore, some scholars suggest whether the physical characteristics of infrared ray have effects on the treatment of chronic atrophic gastritis.OBJECTIVE: To observe the effect of infrared ray on the changes of gastric mucosa tissue in rat models with chronic atrophic gastritis.DESIGN: Randomized controlled observation.SETTING: Hebei North University.MATERIALS: Thirty-five adult Wistar male rats weighing from 180 to 230 g were purchased from Hebei Experimental Animal Center [SCXK (ji) 2003-1-003]. The experiment was disposed with the ethical standard. Sodium salicylate powder produced by Beijing Fangcao Chemical Company (batch number: 890720). The drug was prepared with distilled water. Infrared lamp (220 V, 200 W) was bought by Equipment Division of our college.METHODS: The experiment was carried out in the Experimental Center of Hebei Beifang College from June 2005 to January 2006. ① Experimental intervention: Rats were fed with conventional standard granules for one week. Among them, 8 rats were selected as the normal control group, and other rats underwent model establishment. Rats were perfused with sodium salicylate and alcohol to stimulate gastric mucosa, and then chronic CAG models were established for 8 weeks based on exertion, irregular diet and other factors. Five rats were randomly selected for the check of histopathology before the end of model confirmedly making, and then the model rats were randomly divided into model group and infrared group with 11 in each group. Infrared lamp (220 V, 200 W, 0.76–1.5 μm in wavelength) was used to vertically radiate at the gastric projective area of rats in the infrared group, once a day, ten minutes once for twenty days. The rats in normal group and model group were regularly breed. ② Experimental evaluation: The body mass was weighed every week in 1, 4, 9 and 12 weeks after modeling. The infiltration of inflammatory cells and thickness of gastric mucosa were observed under optic microscope.MAIN OUTCOME MEASURES: ① Changes of body mass; ② pathohistological changes of gastric mucosa.RESULTS: All 30 rats were involved in the final analysis. ① Changes of body mass: From the end of the 4th week, increasing percentage of body mass in the model group and infrared group was decreased gradually as compared with that in the normal group, and there was significant difference (P < 0.05). ② Pathohistological changes of gastric mucosa: Gastric mucosa of rats in the model group was thinner, and atrophic glands, notable inflammatory infiltration and partial intestinal metaplasia were observed under optic microscope. The thickness of gastric mucosa in the infrared group was significantly thicker than that in model control group, and there was significant difference (P < 0.01); the inflammatory cells in the infrared group were less than those in the model group, and there was significant difference (P < 0.05). Morphologic structure and volume of the parietal cells were all recuperated or closed to normal.CONCLUSION: Infrared ray can decrease thickness of gastric mucosa and reduce inflammatory cells of rats with chronic atrophic gastritis, and it has greatly therapeutic achievements.
