Objective To investigate the positive end-expiratory pressure (PEEP) ventilation in the treatment of neurogenic pulmonary edema. Method 64 patients with neurogenic pulmonary edema were treated with the timely use of positive end-expiratory pressure(PEEP) ventilation. Then the curative effect was observed. Result The symptoms of hypoxia, pulmonary edema were had a rapid improvement in ventilation with PEEP. the improvementof heart rate, respiratory rate, oxygen saturation, partial pressure of oxygen, carbon dioxide partial pressure had significant difference compared with that before treatment(P ＜ 0.01).

Objective To investigate the effects of Qi-reinforcing and blood-activating prescription,Qidan Tongmai Tablet(QDTMT) on the IL-10 in the rat model of myocardial ischemia/reperfusion injury.Methods A model of myocardial ischemia/reperfusion injury was reproduced by ligation of left anterior descending branch of the coronary artery.Thirty-six male SD rats were randomly divided into six groups(n=6):sham operation group,model group,Diltiazem Hydrochloride group,QDTMT high-dose group,QDTMT medium-dose group and QDTMT low-dose group.After the left anterior descending branch of coronary artery was occluded for 30 minutes followed by reperfusion for 2 hours,the whole blood was collected via right common carotid artery and the serum level of IL-10 was measured by ELISA.At the same time,HE staining was performed to detect the pathological change in myocardium,and the ultrastructural alterations of rats were observed with transmission electron microscope.Results The contents of IL-10 in serum were increased in QDTMT groups.Electron microscopic examination showed that pathologic changes of myocardiocytes in QDTMT groups were milder than those of the model group.The effects in QDTMT high-dose group were better than that in the low-dose group,and has insignificant difference with Diltiazem Hydrochloride group.Conclusion Qi-reinforcing and blood-activating prescription inhibits the inflammatory reaction by facilitating the expression of endogenous IL-10 and improving myocardial ultrastructural changes after myocardial ischemia/reperfusion in rats.These actions may contribute to its protective effect on the ischemic myocardial cells.

Objective] Observing Cortex Lycii Radicis' effect(Cortex Lycii) on rat insulinoma cells(INS-1) proliferation and apoptosis. To explore the mechanism of Cortex Lycii on Pancreatic Beta Cell Proliferation and apoptosis.[ Methods] After primary culture, cells were randomly divided into blank control group:control,11.1mmol·L-1 glucose,HG,30mmol·L-1 glucose, HG+Cortex Lycii(1g·L-1), HG+Cortex Lycii(2g·L-1), HG+Cortex Lycii(4g·L-1), the survival rate of cells was observed by cell counting kit-8(CCK-8);the apoptosis rate was observed by Annexin V stammg.

Background miRNAs are a group of non-coding small RNA molecules,and they play an important role in regulating the apoptosis of LECs.The biological effects and mechanisams of miRNAs on LECs in agerelated cataract still need to be further elucidated.Objective This study was to investigate the anti-oxidative effects of miR-204 on age-related cataract in vitro.Methods The specimens of anterior lens capsules from agerelated cataract patients and normal donors were collected in Shandong Eye Institution and 20 subjects for each.The expression level of miR-204 was detected and compared between cataractous eyes and normol eyes by real-time fluorescence quantitative PCR (RT-qPCR).HLE-B3 cells,a human LEC line,were cultured,and the oxydative stress models of LECs were established by adding 200 μmol/L H2 O2 in the medium.The models were divided into model control group,miR-204 agomir group,agomir negative control group,miR-204 antgomir group and antagomir negative control group according to the difference of tranfected agents,and normal cells served as the control group.Twenty-four hours after transfection,the expression levels of miR-204 mRNA in the cells of various groups were detected by RT-qPCR to varify the transfection rate.Apoptosis rate of the cells was assayed by flow cytometry.The relative expression levels of TP53INP1 mRNA and p53 mRNA as well as their proteins were detected by RT-qPCR and Western blot,respectively.Results The mean expression level of miR-204 was significantly lower in the anterior lens capsules of cataractous eyes than that in the normal eyes (t=14.21,P＜0.05).The mean apoptosis rate of cells was 1.31±0.12,4.90±0.28,2.60±0.15,4.39±0.20,5.74±0.13 and 4.34±0.63 in the normal control group,model control group,miR-204 agomir group,agomir negative control group,miR-204 antgomir group and antagomir negative control group,respectively.The apoptosis rate was significantly increased in the model control group compared with the normal control group (t =-20.69,P＜0.01) and the apoptosis rate was also increased in the miR-204 antagomir group compared with antagomir negative control group (t =3.79,P＜0.05);while the apoptosis rate in the miR-204 agomir group was significantly declined in comparison with agomir negative control group (t=-12.20,P＜0.01).The relative expression levels of TP53INP1 and p53 mRNA and proteins in the cells were significantly higher in the model control group than those in normal control group (mRNA:t =6.44,11.71,both at P＜0.0I;protein:t =10.72,19.40,both at P＜0.01),and so were between the miR-204 antagomir group and antagomir negative control group (mRNA:t =4.07,3.74,both at P＜ 0.05;protein:t =7.18,10.58,both at P＜0.05).However,the expression levels of TP53INP1 and p53 mRNA and protein were significantly reduced in the miR-204 agomir group in comparison with the agomir negative control group (mRNA:t =-19.28,-10.58,both at P＜0.05;protein:t=-6.50,-6.36,both at P＜0.05).Conclusions miR-204 induces oxidative damage of age-related cataract via targeting TP53INP1,which suggests that the activation of TP53INP1-p53 signaling may be involved in the development of age-related cataract.

Objective To study the diagnostic value of air plethysmography (APG) in deep venous valvular incompetence of lower limbs and the relationship between deep venous reflux and calf muscular pump function. Methods Sixty-five varicose cases (89 limbs) were detected by APG in alterations of venous filling index (VFI), ejection fraction(EF), residual volume fraction(RVF) and outflow fraction(OF). Of 89 limbs, 18 limbs were in GradeⅠ of deep venous reflux, 24 in Grade Ⅱ, 18 in Grade Ⅲ and 12 in Grade Ⅳ. Integrated vectors analysis (Hotelling T 2test) was done with these index. Venography was performed in all patients. Results There were statistical differences in VFI between each two Grades of deep venous reflux except for between Grade Ⅰ and Ⅱ. There were also statistical differences in EF,RVF and OF between Grade Ⅳ and the other Grades. Hotelling T 2test showed significant testing efficiency of APG. ConclusionsDeep venous valvular insufficiency of lower limbs can be assessed by APG. VFI is a reliable quantitative index for evaluating the degree of deep venous reflux. There may be an exponent relation between deep venous reflux and calf muscular pump function.

Three patients with carotid body tumor were treated by surgery in our department from 1994 to 1998. There were 3 females with age from 23 to 40 years old. Among 3 cases, 2 cases were misdiagnosis as neurilemmoma before operation. The size of tumor was 2.5×2.5cm in 1, 3.0×3.0cm in 2. The treatment methods were surgery alone in 2, combined radiotherapy in 1. All patients were cured who had not serious complications. We think that the three symptoms of carotid body tumor are important bases for diagnosis on this disease. However, color B ultrasonography, DSA, CT or MRI also provided informations for useful diagnosis.

Anesthesia plays an essential role in clinical operations. Guiding anesthesia by EEG signals is one of the most promising methods at present and it has obtained good results. The analysis and process of the EEG signals in anesthesia can provide clean signal for further research. This paper used variance threshold method to remove the mutation fast and large interfering signals; and used notch filter to remove frequency interference, smoothing filter to remove baseline drift and Butterworth low-pass filter to remove high frequency noise at the same time. In addition to this, the translation invariant wavelet method to remove interference noise on the signals which was after the classical filter and retained non-stationary characteristics was used to evaluate parameter calculation. By comparing the calculated parameters from treated signal using this paper's methods and untreated signal and standard signal, the standard deviation and correlation has been improved, particularly the major parameters BetaR, which provides better signal for integration of multi-parameter to evaluate depth of anesthesia index for the latter.
