Objective To explore the characteristics of EEG frequency in recruits and veterans and their relationship with depression scale scores.Methods Fifty-five newly enlisted soldiers formed the recruits group and 68 demobilized soldiers the veterans group.A general information survey,EEGs and the Hamilton depression scale (HAMD) were administered to all of the subjects.According to the HAMD scores,35 of the 123 were designated as the abnormal group,while 88 formed the normal one.Eighteen of the 35 with EEG abnormalities served as a doubleabnormal group to be compared with the remaining 17 cases with abnormal HAMD scores and normal EEGs (the single-abnormal group),and 9 of the 18 with higher HAMD scores as the higher group,and the other 9 cases as the lower group.The EEG frequency spectrum and the power percentages from the δ to γ frequency bands were calculated as δ:0.5-4 Hz,(o):4-8 Hz,α:8-13 Hz,β:13-25 Hz,γ:25-40 Hz.Results Forty-six of the subjects (37.4％) had abnormal EEG results,35 had abnormal HAMD scores,and 18 (51.4％ of the soldiers with abnormal HAMD scores) had both abnormalities.The veterans had lower δ band power percentage in all channels than the recruits,but in the (0) band it was the reverse.In the left channels the veterans had lower α and γ band power percentages than the recruits.Compared with the normal,all channels in the EEGs of subjects with abnormal HAMD scores had significantly higher δ band power percentages.The higher the δ band power percentage a subject had,the higher his HAMD score.Conclusion There is some correlation between changes in EEG power percentages and the possibility and severity of depression.Objective and subjective EEG evaluation can help improve the positive rate of diagnosis,and thus the management of the army.

Objective To investigate and analyze the expression of α-SMA and PCNA in abdominal aorta and renal artery in obstructive sleep apnea syndrome(OSAS)combined with hypertension rats. Methods 36 SD rats were randomly divided into normal control group and model group. The model group was subjected to intermittent hypoxia condition for 8h everyday. Rat tail artery pressure was monitored every week and all subjects were sacrificed at 12th week. The level of TNF-α, IL-6, IL-10 and hs-CRP expression in serum were measured by ELISA method. Immunohistochemical analysis was performed on α-smooth muscle actin (α-SMA) and proliferating cell nuclear antigen (PCNA). Results Compared with control group,model rats blood pressure increased significantly (P < 0.01) when exposed for 4 weeks under intermittent hypoxia condition,and reached the peak value of 186mmHg at 12 weeks. The level of TNF-α, IL-6 , IL-10 and hs-CRP in serum were higher than in control group (P < 0.01). Immunohistochemical staining showed that the expression of α-SMA in abdominal aorta decreased more significantly than control group (P < 0.05),while there was a stronger positive expression of PCNA in model group than those in control (P < 0.05). In addition,compared with control rats, model rats showed a higher expression of α-SMA and PCNA significantly in renal artery(P < 0.05). Conclusion The intermittent hypoxia condition could result in higher blood pressure,while the different expression of α-SMA and PCNA illustrate that high pressure show different reconstruction performance in different vascular,underlying different molecular mechanism.

Objective We aimed to understand the awareness of knowledge related to tuberculosis(TB) prevention and treat ment among diabetes mellitus(DM) patients in Urumqi city,their attitudes towards TB patients,treatment behavior and routes of obtaining knowledge,which will provide scientific basis for further health education and promotion.Methods A questionnaire-based investigation was conducted among DM patients who visited out patient clinics or those who were hospitalized from July to December in 2015.Results 599 DM patients were investigated.the general awareness rate among them was 51.13％,and all awareness rate was 4.17％.In all 7-item core knowledge related to TB prevention and treatment,the awareness of TB symptoms,specialized TB clinics,free examination and free treatment policy were the lowest,which were 32.78％,40.40％,36.68％ and 47.65％.Multi variate analysis indicted that ethnic group and educational level were associated factors of awareness rate.6 t.77％ of patients have tendency to discriminate TB patients.81.83％ of patients were willing to learn more knowledge about TB treatment and prevention,and the main route they hoped to learn were social media,literature and specialized publicity materials.Conclusion Awareness of knowledge related to TB prevention and treatment is low in DM patients in Urumqi,particuiarly those of minority ethnic group and lower education.Future health education in those at-risk groups should be enhanced.

Aim: A new derivative LC-MS method was developed for the simultaneous determination of zofenopril and its active metabolite zofenoprilat to investigate the pharmacokinetic characteristics of zofenopril and zofenopri-lat in healthy Chinese volunteers after single and multiple oral doses of zofenopril calcium tablets. Methods: Ten Chinese healthy volunteers were given three single oral doses of 15,30, and 60 mg, respectively, and consecutively the multiple doses of 30 mg. The concentration and pharmacokinetic parameters of both the parent drug and the active metabolite were simultaneously determined by derivative LC-MS method using p-bromophenacyl bromide (p-BPB) as the derivative reagent. Results: After the single oral administrations of 15, 30, and 60 mg of zofeno-pril calcium, there was no significant difference in the t_(1/2) of both zofenopril and zofenoprilat among the three do-ses. The values of AUC_(0-24h) and c_(max) for both zofenopril and zofenoprilat showed the good linearities to the dosage over the dose range from 15 mg to 60 mg. There were no significant differences in AUC_(0-24h) and c_(max) for both com-pounds between female and male volunteers. After multiple oral administration( 30 mg once daily for 6 days ), the average steady state plasma concentration( c_(av)) for zofenopril was (5. 07 ±1. 06) ng/mL with the degree of fluctu-ation (DF) of 14. 26 ± 2. 94. The c_(av) for zofenoprilat was (6. 28 ± 1. 87) ng/mL with the DF of 11. 61 ±4. 68. The accumulation index values for zofenopril and zofenoprilat were 0. 94 ± 0. 31 and 0. 83±0. 13, respec-tively. Conclusion: Both zofenopril and zofenoprilat were demonstrated of linear kinetics after single administra-tion and showed no accumulation after multiple administration of the test zofenopril calcium tablets. There was significant difference in the pharmacokinetic characteristics for zofenopril calcium between healthy Chinese and European volunteers.

OBJECTIVE To investigate the clinical characteristics,treatment and prognosis of laryngotracheal stenosis due to relapsing polychondritis (RP).METHODS The clinical data of 6 patients with laryngotracheal stenosis due to RP were reviewed retrospectively.RESULTS From 1996 to 2006,6 patients with laryngotracheal stenosis due to RP were managed in our hospital.Respiratory tract lesions were diffuse and extensive.Of them,4 patients accepted laryngotracheal reconstruction using surgical flaps with or without pedicle,2 accepted dilation of trachea in thoracic segments.Five patients were cured without recurrence.CONCLUSION Treatment of laryngotracheal stenosis due to RP is very difficult.If the surgical opportunity and methods were selected correctly according to each patient,good results can also be obtained.

Objective To investigate the effect of isoflurane preconditioning on Toll-like receptor 4 (TLR4)-myeloid differentiation factor 88 (MyD88) signaling pathway in ischemic penumbra following focal cerebral ischemia-reperfusion (I/R) in rats.Methods Fifty-four healthy male SD rats,aged 3 months,weighing 250-280 g,were randomly divided into 3 groups (n =18 each):sham operation group (group S),I/R group and isoflurane preconditioning group (group IP).Focal cerebral I/R was induced by middle cerebral artery occlusion.In groups I/R and IP,a nylon thread with rounded tip was inserted into the right internal jugular vein and threaded cranially until resistance was met.The middle cerebral artery was occluded for 2 h,followed by 24 h reperfusion.In group IP,the animals inhaled 2.0％ isoflurane for 2 h,and middle cerebral artery occlusion was performed at 24 h after the end of preconditioning.Neurological deficit was scored at 24 h of reperfusion and then the rats were sacrificed.Five rats in each group were chosen and the brains removed for measurement of the cerebral infarct volume.The right cerebral ischemic penumbra was removed for detection of the expression of HSP60,TLR4,MyD88 protein and mRNA by Western blot analysis and real time-PCR.Apoptosis was detected in the ischemic penumbra in the left 3 rats in each group using TUNEL.Apoptosis index (AI) was calculated.Results Neurological deficit scores and AI were significantly increased,the cerebral infarct volume was significantly enlarged,and the expression of HSP60,TLR4,MyD88 protein and mRNA was up-regulated in groups I/R and IP as compared with group S ( P ＜ 0.05).Isoflurane preconditioning significantly reduced the cerebral infarct volume and decreased neurological deficit scores and AI,and down-regulated the expression of HSP60,TLR4,MyD88 protein and mRNA (P ＜ 0.05).Conclusion The mechanisn by which isoflurane preconditioning protects ischenic penumbra following focal cerebral I/R may be related to inhibition of TLR4-MyD88 signaling pathway.

Objective To investigate the effect of isoflurane preconditioning on the expression of 5-lipoxy-genase (5-LOX) during focal cerebral ischemia-reperfusion (I/R) in rats.Methods Thirty-nine male adult Sprague-Dawley rats weighing 250-300 g were randomly divided into 3 groups (n =13 each):sham operation group (group S); focal cerebral I/R group (group I/R); isoflurane preconditioning group (group Ⅰ).Focal cerebral I/R was produced by mid-cerebral artery occlusion in anesthetized rats.The rats inhaled 2 h of 2％ isoflurane and focal cerebral I/R was produced 24 h later in group I.The neurological deficits were scored at 24 h of reperfusion.The animals were then sacrificed.The brains were immediately removed for determination of the infarct size.The expression of 5-LOX,myeloid differentiation factor88 (MyD88) and nuclear factor kappa B (NF-κB) protein and mRNA was detected using Western blot and RT-PCR respectively.Results Compared with group S,the neurological deficit score was significantly increased,the infarct size was enlarged in groups I/R and I,the expression of 5-LOX,MyD88 and NF-κB protein and mRNA was up-regulated in group I/R,and the expression of 5-LOX mRNA and MyD88 protein and mRNA was up-regulated in group I (P ＜ 0.05).Compared with group I/R,the neurological deficit score was significantly lower,the infarct size was smaller,and the expression of 5-LOX,MyD88 and NF-κB protein and mRNA was lower in group I (P ＜ 0.05).Conclusion Isoflurane preconditioning can reduce focal cerebral I/R injury by down-regulating the expression of 5-LOX and inhibiting MyD88/NF-κB signaling pathway in rats.
