Objective: To observe the clinical effects of combination of propofol,fentanyl and in surgical abortion. Methods: A total of 184 early-pregnant women were randomly divided into two groups.The women in group Ⅰ received propofol 2.5 mg/kg intravenously(n=92),the women in group Ⅱ received the combination of propofol,fentanyl and atropine intravenously(fentanyl 1 ?g/kg,atropine 0.5 mg,propofol 1 mg/kg)(n=92).To compare the efficacy of those two kinds of anesthesia,many measurements were taken, which included the total dose of propofol applied,induction time,recovery time,self-walking time,operative time,blood loss during the abortion,dilatation of the uterine cervix,blood pressure,heart rate,breathe,pain caused by injection and post-operation uterine contraction. Results: Many differences were found in the group who received the combination of propofol with fentanyl and atropine,when compared to those measurements in the group received propofol only.Significantly less(amount) of propofol was needed.The induction time was significantly shorter.The slowing of heart rate,dropping of blood pressure and reduction of breathing were significantly less.The dilation of the uterine cervix was more complete and took much less time.The pain caused by injection and post-operation contraction was significantly less frequent and less severe. Conclusion: Applying the combination of propofol,fentanyl and atropine has several clinical benefits which include less propofol need,less inhibition to the respiration and cardiovascular system,and less pain caused by injection and post-operation contraction.

Objectives:To observe the clinical effects of combination of propofol and misprostol in surgical abortion. Methods:240 women opting for voluntary surgical abortion were randomly allocated to 3 groups, receiving propofol plus misoprostol, lidocaine and routine menthods, respectively. Comparation was made on the effects of easing pain, cervical dilatation, surgical complications, bleeding amount, uterus contraction, patient satisfaction, etc. Results:The propofol and misoprostol group has higher efficacy and safety in surgical abortion than other 2 groups. Conclusions:Application of propofol and misoprostol in surgical abortion should be a recommended choice when patient can afford.

Objective To estimate the frequency of heart valvular involvement in Chinese patients with Takayasu arteritis (TAK) and its correlation with other clinical features. Methods Ninety-one patients with TAK were studied and their clinical manifestations, laboratory test, vascular images and echocardio - gra-phic findings were retrospectively reviewed. The data were compared between patients who had heart valvular involvement and those who had not. Mann-Whitney U-test or Student's t-test, Chi-squared test or Fisher's exact test were used for analysis. Results Aortic regurgitation and mitral regurgitation were both confirmed in 20 (22%) patients. Tricuspid regurgitation and pulmonary valve regurgitation were observed in 10 (11%) and 2 (2%) patients, respectively. Older age at onset, longer disease duration, hypertension and involvement of the ascending aorta were all significantly more frequent in TAK patients with aortic regurgitation (t=2.903, P<0.01; Z=-2.759, P<0.01; χ2=7.918, P<0.01; Z=-4.454, P<0.01) than those without. However, the constitutional symptoms and acute phase reactants [erythrocyte sedimentation rate (ESR) and C reactive protein (CRP)] were not statistically different between patients with and without valvular regurgitation (P>0.05). Aortic valvular pathology examination of the three TAK patients who had underwent aortic valve replacement showed no inflammatory cell infiltration. Conclusion This study has demonstrated that heart valve involvement is common in patients with TAK, mainly in the form of regurgitation, and which may be secondary to hypertension and other cardiovascular complications. We should pay more attention to the screening and treatment of heart valvular involvement in TAK patients.

Objective To analyse the mutation of pathogenic gene TSC2 in tuberous sclerosis complex (TSC). Methods Using polymerase chain reaction-single strand conformation polymorphism(PCR-SSCP), all the 41 exons of TSC2 gene were analyzed in 4 TSC cases(include 1 suspect case) from one family and 1 sporadic TSC case ,and compared with the kin familial controls and kinless normal controls. Results Missense mutation on exon33 1346S→P (4037T→C) of TSC2 was found in 4 familial cases, and no mutation of TSC2 gene was found in the sporadic case and all the health controls. Conclusion Missense mutation on exon33 (1346S→P,4037T→C)is a new discovery in TSC2 gene of patients with TSC.

Objective To explore the positive distribution characteristics and analyse the correlation of common food allergen-specific immunoglobulin E (sIgE) with suspected food allergy in the First Affiliated Hospital of Guangzhou Medical University.Methods Using fluorescence enzyme-linked immunosorbent assay to detect the serum sIgE antibody of 854 patients,including 7 kinds of food allergens (milk,egg white,egg yolk,shrimp,crab,peanut and soybean) from July 2006 to January 2013.Data were processed by statistical software SPSS19.0.Results The positive rates of the 7 kinds of food allergen were 39.3％ (283/720),36.3％ (216/595),9.8％ (28/285),21.2％ (36/170),24.3％ (17/70),14.8％ (9/61) and 10.0％ (5/50).Two hundred and eighty-two patients were detected egg white and egg yolk sIgE,the positive rate of egg white sIgE 59.6％ (168/282) was much higher than the egg yolk sIgE 9.2％ (26/282).The positive rate of the milk and egg white sIgE were different between the age groups and decreased with the age(milk:x2 =792.88;egg white:x2 =658.21,P ＜ 0.01).The degree in level 4 or above of milk and egg white sIgE were 1.08％ (2/186) and 1.12％ (2/178) in positive patients.Five hundred and twenty-eight patients were detected milk and egg white sIgE,26.9％ (142/528) were both positive,sIgE levels in serum of them was moderately correlated (rs =0.758,P ＜ 0.01).Serum sIgE of shrimp and crab was detected in 64 patients,16 cases was positive of the shrimp,17 cases of the crab was positive,both positive in 16 cases,sIgE levels in serum of them were highly correlated (rs =0.973,P ＜0.01).In the simultaneous detection of 34 patients' serum sIgE of peanut and soybean,peanut was positive in 4 cases,soybean was positive in 3 cases,both positive in 2 cases,sIgE levels in serum of them were highly correlated (rs =0.879,P ＜ 0.01).Conclusions Egg white is the major allergen of egg allergy.The correlations of shrimp and crab,peanut and soybean are extremely high,probably because of their homology; egg white and milk are not homologous food,but the levels of sIgE between them display a moderately correlation,indicating the existing of synergistic reaction.

ObjectiveTo observe the effects of enriched environment on depressive-like behaviors induced by chronic stress in rats.MethodsAdult rats were randomly divided into stress group and the control group,then after 21 days of stress,rats were raised in an enrich environment (EE) or standard environment (SE)for 28 days.Open field test,forced swimming test and sucrose preference test were used to detect depressive-like behavior in rats.Results ( 1 ) Open field test showed that grid crossing,standing and rearing in stress ( no gap)rats were significantly reduced ( 13.88 ±4.38 vs 45.00 ± 10.19,9.13 ±2.54 vs 16.38 ±4.11 and 4.78 ± 1.39vs 10.51 ± 2.52 ; n =8 ; P＜ 0.01 respectively) ; but grid crossing and standing in stress + EE rats were significantly increased than stress + SE rats (41.61 ± 10.53 vs 26.25 ± 6.18 and 16.79 ± 3.49 vs 11.25 ± 3.12 ; n =8 ; P＜0.01 and P＜0.05 respectively).(2) Sucrose preference tests showed that sucrose consumption and sucrose preference％ in stress ( no gap) rats were significantly decreased than those in the control group ( 5.22 ± 0.94 vs 10.61 ±2.59 and (49.11 ±6.77)％ vs(63.38 ±8.36)％ ; n=8; P＜0.01 respectively).(3) Forced swimming test showed that immobility time was increased in stress ( no gap) rats ( ( 19.5 ± 5.43 ) s vs ( 12.75 ± 3.9 ) s; n =8 ; P ＜ 0.05 ) and was restored by EE compared to SE rats ( ( 10.25 ± 3.57) s vs ( 17.75 ± 5.45 ) s; n =8 ; P ＜ 0.05).ConclusionChronic stress can reduce depressive-like behaviors,and EE can restore depressive-like behaviors induced by chronic stress.

Objective To analyse distribution of age and gender characteristics of specific IgG(sIgG)antibodies and specific IgE (sIgE)antibodies of 13 types of food allergens in patients with food anaphylaxis,and to explore the relationship between sIgG and sIgE in food anaphylaxis.Methods 314 cases of patients from 2009 to 2012 were selected as subjects,and divided into underage group(1 63 cases)and adult group(1 5 1 cases).Serum sIgG of 13 types of food allergens were detected by using enzyme linked immu-nosorbent assay,serum sIgE of these food allergens were detected by using immune capture.Results 80.25% of the patients were sIgG-positive,and no obvious gender differences were found;while the positive rates of sIgG in the underage group(94.48%)were higher than that in the adult group(64.90%),there were statistically significant differences(P < 0.05 ).34.39% of the patients were sIgE-positive.The positive rates of sIgE in male patients(40.68%)were higher than that in female patients(26.28%),and that in the underage group(55.21%)were also higher than that in the adults group(1 1.92%),there were statistically significant differences(P <0.05).Conclusion The total positive rates and its distribution characteristics of sIgG and sIgE of same food aller-gens were obviously different.Food anaphylaxis might be associated with age,gender,food types and individual diversity.

Background Corneal confocal microscopy can denamically offer the morphological image of corneal cells at cellular level.To find out the dynamic change of corneal thickness and morphology of corneal cells with aging is very important for the design of corneal refractive surgery.ObjectivePresent study is to find out the important relevance of dynamic change of corneal thickness and morphology of corneal cells with aging and the design of corneal refractive surgery and investigate the influence of age on central corneal tissue and characterize precisely the anatomy of cornea by in vivo confocal microscopy.Methods122 eyes of 122 normal subjects were enrolled in this study with the age from 18 through 80 years old.The subjects were diagnosed as emmetropia in the Center of Tianjin Medical University from August 2003 to December 2007.All eyes were examined in vivo by confocal microscopy.The cell morphology,cell density and corneal thickness were measured by confocal microscopy.The relationship of central corneal tissue change and age was evaluated.ResultsThe density of corneal superficial basement epithelial cells showed a significantly negative correlation with age (r=-0.355,P=0.017).The keratocyte density in the anterior and posterior stroma indicated a significantly negative correlation with age (r_1=-0.462,P=0.001;r_2=-0.403,P=0.016).The thickness of corneal epithelium cells had a significantly negative correlation with age (P=0.02).The mean value of total corneal thickness and stromal thickness in high myopic eyes was (523.2±26.20)μm and (468.4±20.72)μm respectively,presenting a significantly negative correlation with age (r_1=-0.552,P=0.014;r_2=-0.545,P=0.035).A significantly negative correlation was also found in endothelial cell areas and density with age (r_1=0.417,P=0.004;r_2=-0.598,P=0.002).The percentage of polymorphological corneal endothelial cells was considerably increased(r=0.417,P=0.004)but that of pleomorphism cells was significantly decreased in >60-year-old population compared with younger subjects (r=-0.598,P=0.002).The morphology of corneal basement cell,anterior stroma cytocyte and endothelial cell were normal in younger subjects,and enlargement of the cells in size,decreases of number and density of the cells were found in >60-year-old subject.ConclusionThe anatomy and histology of the central cornea in young subjects exist discrepancy from older ones.The corneal hisological changes with aging include thinner thickness of epithelium,thinner thickness of cornea,decreased density of keratocyte and endothelial cells and increased size of endothelial cells.Corneal thickness is asymmetric and seems to undergo age-related anatomic changes.
