Objective To investigate the anxiety status of male partner involved in induced abortion and to analyze influencing factors related.Methods Male partners of the patients undergoing induced abortion in the gynecology and obstetrics department of a hospital in Kunming in April and May in 2015 were selected and a questionnaire survey was conducted.Self-rating Anxiety Scale (SAS) was used to measure the anxiety status and SPSS 17.0 was used for statistical analysis.Results A total of 53 out of 205 male partners were found to have anxiety symptoms (25.9％),with 44 cases of mild anxiety (21.5％),8 cases of moderate anxiety (3.9％) and 1 case of severe anxiety (0.5％).The main related risk factor was times of pregnancy (OR=3.35) while the protective factors were level of education (OR =0.60),times of induced abortion (OR =0.20) and age (OR =0.32) Conclusion When abortion occurs,the male partner's anxiety appears,mainly with mild and moderate one,and female's emotion are also affected.It is important to strengthen health education and popularize contraceptive knowledge so as to reduce the incidence of anxiety.

Drug dependence has been a severe social and health problem,which has caused serious economic losses and social disorder in China.The critical problem in drug dependence is repeated relapse even after detoxification.We have been contributed to the research of neurobiological mechanisms,clinical characteristics,and interventions of craving after withdrawal from addicting drugs.We have systemati-cally studied the change of drug seeking behavior and craving after withdrawal from cocaine,and further investigated the neural anatomic pathway,long-term neuroplasticity,and neural signal pathways which involved in the change of drug seeking behavior.According to the situation of dug abuse in China,we investigated the characteristics in the expression of incubation of craving after withdrawal from opiate.We have primarily found the neural anatomic pathways and neural plasticity mechanisms which contribute to the process.We have also demonstrated the psychological characteristics and neurobiological mechanisms of craving induced by opiate and its long-term maintenance resulting from learning and memory,chronobiology and imaging.Our findings have provided evidence for effective inventions on preventing relapse after abstinence in addicts.Abstract:SUMM ARY Drug dependence has been a severe social and health problem,which has caused serious e-conom ic losses and social d isorder in China.The critical problem in drug dependence is repeated relapse even after detoxification.W e have been contributed to the research of neurobiologicalmechanisms,clini-cal characteristics,and interventions of craving afterwithdrawal from add icting drugs.W e have systemati-cally stud ied the change of drug seeking behavior and craving afterwithdrawal from cocaine,and further investigated the neural anatom ic pathway,long-term neuroplasticity,and neural signal pathways which involved in the change of drug seeking behavior.Accord ing to the situation of dug abuse in China,we in-vestigated the characteristics in the expression of incubation of craving after withdrawal from opiate.W e have primarily found the neural anatom ic pathways and neural plasticity mechanisms which contribute to the process.W e have also demonstrated the psychological characteristics and neurobiologicalmechanisms of craving induced by opiate and its long-term maintenance resulting from learning and memory,chrono-biology and imaging.Our find ings have provided evidence for effective inventions on preventing relapse after abstinence in add icts.

Objective To observe the efficacy and safety of different initial doses of nebulized budesonide inhalation (BI) in infants and young children with moderate to severe asthma exacerbations.Methods A multi-center,parallel controlled clinical trial was performed during Sep 2008 to Apr 2010 in three hospitals,which were Department of Pediatrics,Shanghai Jiaotong University Affiliated Shanghai First People's Hospital,Department of Pediatrics,Shanghai Jiaotong University School of Medicine Affiliated Xinhua Hospital,and Department of Respiratory,Fudan University Affiliated Children's Hospital.One hundred and fifty children aged 6 to 36 month with moderate to severe asthma exacerbations were randomly divided into two groups.The high-starting-dose group was treated with a dose of 1 mg nebulized BI every 8 h for 2 days,while the conventional-starting-dose group was treated with a dose of 0.5 mg cvcry 8 h for 4 days.The terbutaline sulfate aerosol liquid was administered with a dose of 2.5 mg each time as needed.The primary outcome measures were severity scores,which were assessed at admission (0 h),and 8 h,16 h,24 h,48 h,72 h after treatment separately.The secondary outcome measures included the use of β2 receptor agonist,the systemic use of corticosteroids,average length of hospital stay and total cost.The data was analyzed with SPSS 13.0.Results (1) The clinical severity scores were significantly decreased at all time points after treatment in both groups (P ＜ 0.05).Compared with conventional starting-dose of BI,high starting-dose of 3.25 ± 1.82,P ＜ 0.01).(2) The terbutaline doses and the systemic corticosteroids do-ses were significantly reduced in high-starting-dose group compared with conventional-starting-dose group [(16.27 ± 12.99) mg vs (22.90 ± 18.27) mg,P ＜ 0.05 ; (4.54 ± 18.18) mg vs (11.16 ± 21.34) mg,P ＜ 0.05).The average length of hospital stay and the total cost of the two groups showed no significant differences (P ＞ 0.05).(3) There were no side effects associated with BI.Conclusion Compared with conventional treatment,high-starting-dose of BI can control symptoms fast and reduce the use of systemic corticosteroid without any side effects.BI improved symptoms more quickly at 8 h (2.87 ± 1.60 vs 4.48 ± 2.24,P ＜ 0.01) and 16 h (2.48 ± 1.56 vs

AIM: To investigate the effect of ligustrazine on hydrogen sulfide (H_2S) system in pulmonary hypertension induced by hypoxic hypercapnia in rats. METHODS: Thirty Sprague-Dawley rats were randomly divided into 3 groups: control group (C), hypoxic hypercapnia group (HH), and hypoxic hypercapnia+ligustrazine group (HH+L). The change of hemodynamics was measured. The ratio of vessel wall area and total area of arteriae pulmonalis were observed under light microscope. The apoptosis of arteriae pulmonalis was tested with TdT-mediated dUTP nick end labeling (TUNEL), and the apoptosis index was calculated. Plasma level of hydrogen sulfide and activity of hydrogen sulfide generating enzymes in homogenates of rat lung tissue were evaluated by sensitive modified sulfide electrode method. Cystathionine-γ-lyase (CSE) mRNA in lung tissues was determined by RT-PCR. RESULTS: The level of mean pulmonary arterial pressure, the ratio of vessel wall area/total area and the right ventricle/left ventricle+septum were significantly higher in HH group than those in C group, and the value was obviously lower in HH+LTZ group than that in HH group (all P<0.01). The mean carotid arterial pressure of 3 groups had no significant difference (P>0.05). The apoptotic index of arteriae pulmonalis in HH group and HH+LTZ group was significantly lower than that in C group, and that in HH+LTZ group was significantly higher than that in HH group (P<0.05 or P<0.01). Plasma level of H_2S, the activity of H_2S generating enzymes in homogenates of rat lung tissue, cystathionine-γ-lyase (CSE) mRNA in lung tissues in HH group were significantly lower than those in C group (all P<0.01), and those in HH+LTZ group were significantly lower than those in HH group (all P<0.01). CONCLUSION: Ligustrazine up-regulates the expression of cystanthionine-γ-splitting enzyme (CSE), enhances the activity of CSE and increases the level of H_2S to prevent pulmonary hypertension induced by hypoxic hypercapnia.

Objective To explore the influence of genetic and environmental factors on emotional and behavioral problems in children and adolescents using twins quantitative method. Methods One hundred fifty-six twins pairs, aged from 6 to 18, were included in the present study. The parental version of the strengths and difficulties questionnaire (SDQ)was used to evaluate their emotional and behavioral problems. The DNA test of twin zygosity was conducted using DNA extracted from buccal mucosa or venous blood samples. The influence of genetic and environmental factors on emo-tional and behavioral problems was analyzed using structural equation modeling(SEM). Results Shared environment and special environment had impact on emotional symptoms and their contribution to the total variance of emotional symp- tom was 0.42 and 0.58, respectively. Prosocial behavior was mainly affected by shared environment and the contribution of shared environment to the total variance of prosocial behavior was 0.89. Genetic factors had greater influence on hyperac-tivity/attention deficit and the contribution of genetic factors to the total variance was 0.62. Shared environment had more influence on conduct disorder and the contribution of shared environment to total variance was 0.56. Heredity, shared envi-ronment and special environment had impact on peer problems and their contribution to the total variance was 0.24, 0.33 and 0.43, respectively. Conclusion In child and adolescent period, emotional symptoms are only affected by environ-ment, while behavior problems are affected by the combination of heredity and environment. Different behavior problems are affected by different genetic and environmental factors.

Objective: To analyze the mental health status and its impact factors among nurses, finding ways to improve the mental health of nurses. Methods: A total of 13 425 female healthcare workers aged from 18 to 65 were selected as study objects. The survey was conducted with unified design questionnaire. The survey included the basic situation of the individuals and SCL-90 questionnaire. Comparing the female doctors, the mental health status and its impact factors of nurses were analyzed. Results: The income, age, education and occupation, which include shift work, heavy work load and overtime work are different between nurses and doctors. The main mental health problems of nurses were obsessive-compulsive symptoms, depressive symptoms and somatization. The results of univariate analysis indicated that shift work, overtime work, and heavy work load affected the positive rate of each factor. The results of multivariate analysis showed that occupation, shift work, overtime work, and heavy work load have significant adverse effects on the positive rate of the total score in female healthcare workers (P<0.01) . The positive rate of each dimension of SCL-90 in nurses is significantly higher than that of doctors. Conclusion The mental health problems of nurses are significantly higher than doctors. The main reasons are low occupational level and adverse workstyles which include shift work, heavy workload and so on. Health administration and hospital management departments should pay much more attention to the mental health of nurses, improving their mental health through a variety of ways.

Objective In order to know the changes of serum pertussis IgG antibody level and the percent-age of white blood cells and lymphocytes in blood routine of children with IgG antibody positive,it is easy to diagnose and treat according to the clinical symptoms and examination results of children.Methods 485 cases of children in Shangdong Provincial Hospital were randomly enrolled as the test subjects,and pertussis anti-body IgG(PT -IgG)detection and blood cell detection were carried out.Results The levels of Pertussis IgG antibody were positive in 90 cases,the positive rate was 18.6%,pertussis IgG antibody level of children aged 8- <10 years old was the highest,2- <4 years old took the second place,10-14 years old were with the low-est levels.Among the patients with positive pertussis antibody levels,white blood cells in total were more than 20×109/L and lymphocyte percentage reached more than 60% in 19 cases,the positive rate was 21.1%,of which 6- <8 years old the highest positive rate was 10-14,the lowest.Conclusion IgG antibody of pertussis incidence is higher in children under 10 years old,the changes of white blood cells and lymphocytes mainly in children under the age of 8,the general course of the disease can be up to 2-3 months,so the need for early diagnosis and treatment,strengthen the immunity of pertussis vaccine is very necessary for children.

OBJECTIVETo explore the influence of genetic and environmental factors on the executive function of twin children.

METHODSThe executive function of 122 twin pairs from Chongqing (aged from 6 to 18 years) were investigated with the perseverative errors of the Wisconsin Card Sorting Test. Structural equation modeling was performed to evaluate the effects of the additive genetic factors (A), dominance genetic latent factors (D) and individual specific environmental factors (E) on the executive functions.

RESULTSThe effects of D and E on perseverative errors were 0. 77 (95%CI: 0.65-0.84) and 0.23 (95%CI: 0.16-0.35), respectively. The probability of perseverative errors showed a significant negative correlation with family functioning and with the total GHQ-12 scores of the fathers and mothers (r:-0.335, -0.335, and -0.219, respectively, P<0.01). Perseverative errors were not significantly correlated with the parenting styles and stress life events.

CONCLUSIONPerseverative errors are influenced by a common dominance genetic latent factor and individual specific environmental factors, but the role of environmental factors such as family functioning and parental health can not be ignored.

BACKGROUND:Alzheimer's disease is a degenerative neurological disorder characterized primarily by cognitive impairment.Acupuncture is a kind of traditional Chinese medicine therapy for treating Alzheimer's disease,but its mechanism is not yet clear. OBJECTIVE:To observe the effects of electroacupuncture with"Zhi San Zhen"on the Notch signaling pathway,β-amyloid protein(Aβ)and synaptic plasticity in 5xFAD mice. METHODS:Sixteen male,6-month-old 5xFAD mice,SPF-grade,were randomly divided into the electroacupuncture with"Zhi San Zhen"group(electroacupuncture group)and the model group,with eight mice in each group.Eight SPF-grade,male,6-month-old C57BL/6 mice were used as the wild control(wild)group.The electroacupuncture group received electroacupuncture with"Zhi San Zhen"intervention,5 times a week for 4 consecutive weeks.The model group and the wild group did not receive electroacupuncture intervention.The Morris water maze was used to preliminarily assess their learning and memory abilities.Thioflavin S staining was performed to detect Aβ plaque deposition.Western blot and real-time quantitative polymerase chain reaction(RT-qPCR)were used to measure the expression levels of transmembrane receptor protein Notch-1,Notch 1 intracellular domain(NICD),hairy and enhancer of split 1(Hes 1),hairy and enhancer of split 5(Hes 5),synaptophysin(SYN),postsynaptic density protein-95(PSD-95),and Aβ. RESULTS AND CONCLUSION:Compared with the model group,the wild group and the electroacupuncture group showed shortened escape latency,increased platform crossing times,and longer target quadrant dwell time(P<0.05).Compared with the wild group,the model group had significantly increased deposition of Aβ plaques,while electroacupuncture with"Zhi San Zhen"inhibited the deposition of Aβ plaques in the hippocampus of 5xFAD mice(P<0.05).Compared with the wild group,the model group had decreased mRNA levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5 in the hippocampal tissue of mice,and increased mRNA levels of Aβ(P<0.05).Electroacupuncture with"Zhi San Zhen"increased the mRNA levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5 in the hippocampal tissue,and decreased the mRNA level of Aβ(P<0.05).Compared with the Wild group,the model group had decreased protein expression levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5 in the hippocampal tissue of mice,and increased protein expression levels of Aβ(P<0.05).Electroacupuncture with"Zhi San Zhen"upregulated the protein expression levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5,and inhibited the protein expression of Aβ(P<0.05).To conclude,electroacupuncture with"Zhi San Zhen"can improve the learning and memory abilities of 5xFAD mice,possibly by inhibiting the deposition of Aβ protein and activating the Notch signaling pathway in the hippocampus to enhance synaptic plasticity.
