Objective To explore the effect of carnosine in the expression of B cell lymphomal/leukemia-2 (bcl-2) and bcl-2-associated X protein (bax) after focal cerebral ischemia in rats. Methods Thirty male SD rats (SPF scale) were ran?domly divided into 3 groups:sham-operated group, model group and carnosine treated group (n=10 for each group). The mid?dle cerebral artery occlusion model (MCAO) was induced in model group and carnosine treated group. Rats were received carnosine [1 000 mg/(kg·d), orally] in carnosine treated group, and the other rats were received the same volume of normal sa?line (NS) in shame-operated group and model group. The neurological deficit score was used to evaluate the neurological function at 24 h and 72 h after MCAO. Morphological changes were observed by HE staining. TCC staining was used to label infarct volume, and immunohistochemistry was used to detect the expression of bcl-2 and bax. Results Compared with model group, the score of neurological function and infarct volume were significantly declined in carnosine treated group at 72 h after injury (P<0.05 or P<0.01). The changes of ischemic impairment were lighter in carnosine treated group than that of model group. Compared with sham-operated group, the expression levels of bcl-2 and the ratio of bcl-2/bax were de?creased while the expression of bax was increased in model group (P<0.05). Compared with model group, carnosine could sig?nificantly increase the expression of bcl-2 and the ratio of bcl-2/bax, and reduce the expression of bax (P<0.01 or P<0.05). Conclusion Carnosine can enhance bcl-2 expression, decrease bax expression and increase the ratio of bcl-2/bax, which is likely to be one of the mechanisms of neuroprotection.

Objective:To investigate auricular lobule index difference in healthy young female of different height or weight, and to provide an additional reference for otoplasty of auricular lobule.Methods:Subjects were made up of 266 healthy young females of Henan residents. Their height, weight, physiognomic ear breadth, morphological ear breadth, physiognomic ear length, morphological ear length, auricular lobule length, auricular lobule breadth were measured and calculated. All the data were analyzed by SPSS 15.0 software.Results:We obtained the means, standard deviation of each items, and data were treated statistically. In the 266 subjects, average height was (162.9±4.1) cm, weight (55.3±6.5) kg, morphological ear breadth (4.9±0.6) cm, morphological ear length (2.9±0.3) cm, physiognomic ear breadth (6.2±0.4) cm, physiognomic ear length (3.3±0.3) cm, auricular lobule breadth (1.6±0.3) cm, auricular lobule length (1.8±0.2) cm, lobule physiognomic ear breadth index (25.6±4.9)%, lobule-physiognomic ear length index (53.69±7.69)%, and auricular lobule index (91.4±19.3)%. The differences among the indices mentioned above were of statistical significance ( P<0.05); the indices of subjects of different height were significantly different ( P<0.05); the indices of subjects of different weight were of no statistical difference. ( P>0.05). Conclusions:The subjects of different height or weight have no different morphological ear breadth, morphological ear length, physiognomic ear breadth, physiognomic ear length, auricular lobule length, lobule-physiognomic ear length index and auricular lobule index; hence, the indices are no related to body height and weight. However, the subjects of different height have different auricular lobule breadth and lobule-physiognomic ear breadth index.

Objective To study the induction of imiquimod on interferon-gamma (IFN-γ) in the peripheral blood of patients with condyloma acuminatum. Methods Twenty-two adult patients with condyloma acuminatum and twenty health control were sequentially enrolled in this study. Serum levels of IFN-γmRNA were measured by realtime polymerase chain reaction in 22 cases with condyloma acuminatum before and after treatment with imiquimod for 8 weeks and 20 health control. Results The serum level of IFN-γ mRNA before treatment was significantly lower than that of health control (t = - 2.87, P = 0.0071). Expression of serum IFN-γmRNA in condyloma acuminatum was significantly increased after 8 weeks imiquimod treatment (t = - 2.51 ,P = 0.0159). The serum level of IFN-γmRNA had no significant difference compared with after treatment group and health control group (t = - 1. 07, P =0. 2922). Conclusion Imiquimod could increase the low expression of IFN-γ mRNA in patients with condyloma acuminatum.

Objective To evaluate the clinicopathological characteristics and immunophenotype of solitary fibrous tumor (SFT),which is able to provide the basis for clinical diagnosis and prognosis,differential diagnosis and predictable prognosis.Methods Data from 11 cases of SFT were investigated by immunohistochemical.Results Histologically,SFT was composed of spindle cells,which arranged in fascicles pattern,as well as the collagen and branch vessels.Malignant SFT had higher and crowed cellularity with significant pleomorphism,numerous mitoses and putrescence.Positivity for bcl-2 and CD34 was observed in all SFT.Eight tissues showed CD99 positivity,one showed s-100 positivity,all 1 1 tissues showed Ckpan negativity.Conclusions SFT has originated from different sites,which should be distinguished with fibrosarcoma and other spindle cell neoplasms.More attentions should be paid to malignant SFT and focus on the follow-up visit.

Objective:To study the effect of airway IL-4RA gene transfer on asthma-associated expression of STAT6 in the mice of allergic asthma.Methods:Forty BALB/c mice were randomly divided into four groups:blank control,asthma model,asthma model administered by pLNC-laz,and asthma model administered by glucocorticoid and pLNC-IL-4RA.The ten mice in each groups were sensitized by i.p.injection of 10 ?g of OVA emulsified in 40 mg of aluminum hydroxide in a total volume of 200 ?l on the days of 1st,7th and 14th.On the 15th day,the mice were challenged via airways with OVA for 7 days,20 min a day,blank control were sensitized by i.p.injection of 200 ?l pH=7.4 PBS on days 7 and 14.Asthma model was administered by pLNC-laz or pLNC-IL-4RA for 3 days beginning at the 12th day.The mice of the group with glucocorticoid was administered with glucocorticoid on the 15th day for 7 days.24 hours after the last challenge,the mice were sacrificed by bloodletting.Serum OVA-specific IgE and blood Eosinophils were measured.The lungs were fixed by immersion in 10% formalin.Expression of STAT6 was identified by immunohistochemistry.Results:It was shown that pLNC-IL-4RA was integrated to the genomic DNA of pneumonic tissues.Retrovirus-mediated delivery of IL-4RA to airways of the asthma mice weakened airway eosinophilia triggered by either IL-13 or IL-4.Furthermore,IL-4RA delivered by retrovirus was expressed in airways of the mice with allergen sensitization,resulting in significiant reduction of expressing level of asthma-associated STAT6 in the experimental mice of allergic asthma.Conclusion:Retrovirus mediated delivery of IL-4RA to airways reduces expression of STAT6 in pneumonic tissues of asthmatic mice.Thus,the gene theraphy can be a potential therapeutic option to treat and control chronic airway inflammation and asthmatic symptoms.

A Co2+ ion-mediated formaldehyde imprinted polymer ( MIP) was prepared by coordination polymerization method in present work and its surface structure characterized by using IR spectrum and scanning electron microscope ( SEM). Inversed phase gas chromatography ( IGC) technique using this formaldehyde imprinted polymer as stationary phase was utilized to investigate on the retention selectivity, isotherm adsorption and adsorption thermodynamics for this imprint material toward the template and its structural analogue. Also, the ability of this polymer in the removal of formaldehyde from room atmosphere was explored. Results indicated that the capacity of the template on the molecularly imprinted polymers (MIPs) column was much higher than that of aldehyde and the lower column temperature and flow rate of carrier gas was beneficial for the selective retention of imprint material toward the template molecule, possessing a higher capacity factor of 61. 1 for the template and a higher separation factor of 10. 66 for this imprint polymer toward formaldehyde and aldehyde under the optimized chromatographic conditions ( column temperature: 363 K;flow rate of carrier gase: 7. 0 mL/ min; injection volume: 3. 0 μL). An approximate linear adsorption isotherm for the template and a BET Ⅲ one for the analogue on the MIPs was observed. In addition, this molecularly imprinted polymer was shown with higher capability in the removal of formaldehyde from room atmosphere.

Objective:To analyze the maternal gestational weight gain (GWG) in women with pre-pregnancy obesity and its relationships with adverse pregnancy outcomes.Methods:This retrospective cohort study recruited 513 obese women (pre-pregnancy body mass index ≥30 kg/m 2) with singleton pregnancy in Beijing Obstetrics and Gynecology Hospital, Capital Medical University from January 2014 to December 2016. All participants were divided into three groups according to GWG: inadequate (GWG<5 kg, n=83), adequate (5 kg≤GWG≤9 kg, n=154), and excessive (GWG>9 kg, n=276) groups. Chi-square test, Fisher's exact test, Kruskal-Wallis test, and Mann-Whitney U test were used to compare the clinical data among the three groups, including GWG, pregnancy and neonatal outcomes, and labor process. Multivariate logistic regression was performed to analyze the association between maternal GWG and main pregnancy complications associated with obesity. Results:(1) Among 238 participants who gained more than 2.0 kg in the first trimester, 75.6% (180/238) were in the excessive group, while the rate was 34.9%(96/275) among the participants who gained less than 2.0 kg. (2) Postpartum body mass index retention (body mass index at six weeks postpartum minus pre-pregnancy body mass index) was the highest in the excessive group, followed by the adequate group and the inadequate group [0.8 kg/m 2 (0.0-2.2 kg/m 2) vs -0.7 kg/m 2 (-1.6 to 0.0 kg/m 2) vs -2.5 kg/m 2 (-3.2 to -1.5 kg/m 2), all P<0.05]. (3) The rates of primary cesarean section in the inadequate and adequate groups were 29.9% (20/67) and 32.6% (42/129), which were lower than that in the excessive group [43.3% (104/240), χ2=3.955 and 4.047, both P<0.05]. There were no statistically significant differences in the incidence of gestational hypertension, small/large for gestational age, or other major adverse pregnancy outcomes among the three groups (all P>0.05). The weight gain in the first trimester and before the oral glucose tolerance test were not correlated with gestational diabetes mellitus (GDM) ( aOR=1.038, 95% CI: 0.986-1.094, P=0.157; aOR=1.055, 95% CI: 1.000-1.113, P=0.051). The maternal weight gain of women with GDM during the 2nd, the 3rd, and the whole trimesters were lower than women without GDM respectively [3.0 kg (1.3-4.0 kg) vs 3.0 kg (2.0-5.0 kg), 4.0 kg (2.0-6.0 kg) vs 6.0 kg (4.0-8.0 kg), 9.0 kg (5.0-12.0 kg) vs 10.7 kg (7.5-15.0 kg); Z =-2.938, -6.352 and-4.104, all P<0.01]. Conclusions:In women with pre-pregnancy obesity, the first trimester is the critical window to control maternal GWG. GWG guidelines recommended by the Institute of Medicine could help to reduce the weight retention at six weeks postpartum, but couldn't reduce the risk of GDM, gestational hypertension, small/large for gestational age, or other major adverse pregnancy outcomes.

Objective: To investigate the effects of major family structure changes on depression, anxiety and stress symptoms of college students, and to provide theoretical basis for mental health promotion and prevention. Methods: A questionnaire survey was conducted among 9 779 college students from 6 universities, including Jiangxi University of Finance and Economics, Shangrao Normal University, Gannan Normal University, Fujian Polytechnic Normal University, and Changjiang University, by using the Depression, Anxiety and Stress Scale 21 Items (DASS 21). Results: The prevalence rates of depression, anxiety and stress symptoms among college students were 27.4%, 42.0% and 17.4%, respectively. Univariate analysis showed that family structure was associated with anxiety and stress symptoms ( χ 2=8.40,13.08, P <0.05). Multivariate Logistic regression analysis showed that specific family structure other than single or two parent family was positively correlated with anxiety( OR =1.89,95% CI =1.05- 3.42 ) and stress symptoms ( OR =2.48, 95% CI =1.36-4.50), family structure changes due to parental divorce was positively correlated with stress symptoms ( OR =1.53,95% CI =1.05-2.20)( P <0.05). Conclusion The occurrence of depression, anxiety and stress symptoms of college students is related to the type of family structure and the changing factors. Colleges should pay more attention to the mental condition of college students with family structure changes, and deliver various mental health promotion services including psychological counseling and health education.
