Objective To explore the relationship between parental marital quality and depressive behavior in children.Methods Using the method of stratified cluster random sampling,1 311 mothers whose children were 4 to 7 from Shenzhen' s kindergartens were randomnly selected and filled out Achenbach Child Behavior Checklist(CBCL 4/16) and Chinese Marital Quality Questionnaire.The survey results were analyzed using SPSS statistical package.Results ①In 1 311 children,the detection rate of depressive behavior was 3.28％ (43/1 311).Based on the detection rate,the difference of children depressive behavior was not statistically significant between the gender(x2=2.860,P＞0.05),but was statistically significant among different ages(x2 =17.146,P＜0.01).Increasing depressive behavior was observed with age.②The normal group of behavioral and emotional development was better than the group which had depressive behavior in marital quality(63.65±14.86) and 10 indicators of marital quality including personality magnanimous(6.03± 1.49),communication of couple(6.04± 1.48) and family roles (6.03± 1.48).There were statistical significances in marital quality(t=4.415,P＜0.05) and its 10 indicators,which was communication of couple(t=4.891,P＜ 0.05),conflict resolution (t=4.229,P＜0.05) and leisure activities(t=4.084,P＜0.05),were showed significant differences between the two groups.③The relationship between parental marital quality and depressive behavior in children were negatively correlated(r=-0.070--0.352).The better marital quality,the lower incidence of children depressive behavior,and the impact of marital quality for younger children was more significant.④In the indicators of the marital quality,communication of couples(B=-0.318,P＜0.01),and attitude towards offspring and marriage(B=-0.275,P＜0.01) could predict children depressive behavior.Conclusion It is important to improve marital quality and creat harmonious family spiritual enviromnent for reducing the incidence of children's depressive behavior.

Objective To investigate the early comprehensive intervention on neonatal hypoxic ischemic encephalopathy (HIE) effects and the biological mechanisms.Methods 120 cases of HIE were randomly divided into intervention group and control group.Under the basis of drug treatment,the intervention group were given the different perceptual stimuli,audiovisual stimulation,active and passive limb training early comprehensive intervention,the control group only to normal drug treatment.The mental development index(MDI) and psychomotor develo pmental index (PDI) were applied after 3,6,12,and 18 months.S100B protein levels were detected using enzyme immunoassay.Results MDI score in the intervention group with HIE,from the beginning of the 12 month,was higher than that in the control group,there was significant differences (12th month:(96.6±9.4)vs (86.8±9.5),P<0.01).PDI score from the beginning of the 6 month,was higher in the intervention group with HIE than that in the control group,there were significant differences (6th month:(91.6±9.2)vs (82.2±11.0),P<0.01).Serum S100B protein level has a tendency to fall for all HIE patients with the old growth.Born in two groups of serum S100B protein levels were higher in neonate period,but there was no difference(P>0.05).From the beginning of the 3rd month,serum S100B protein levels in the intervention group were reduced significandy,compared with the control group at each time point level(3rd month:(1.29±0.15)ng/L vs(1.40±0.14)ns/L;6th month:(1.06±0.21)ng/L vs(1.26±0.22)ng/L,P<0.01).Conclusion Early intervention can improve the mental and motor development of children with HIE,and serum S100B protein is involved in the mechanisms.

Objective To investigate the effect of three kinds of skin external use in the prevention and treatment of radiation dermatitis in patients with nasopharyngeal carcinoma. Methods 120 patients with nasopharyngeal carcinoma who were treated form August 2014 to October 2015 were divided into three groups by random number table method, namely, aloe vera gel group, triethanolamine cream group, radiation treatment of skin protectants (lifuning) group. Except for different medications among the groups, the other conditions remained relatively consistent. 3 groups were compared in the radiotherapy classification, area, local pain score, and topical drug costs during the radiotherapy and the radiation dose when radiation dermatitis occurred the first time. Results Three kinds of skin external use had a preventive effect, but the effect was different. Three groups′ patients with radiation dermatitis incidence was 100%, but occurred at different levels. Aloe vera gel cream group and triethanolamine group were mainly for gradeⅡradiation dermatitis, grade IV radiation dermatitis occurred in 2 cases and 4 cases, lifuning group were mainly for grade Ⅰ and grade Ⅱ radiation dermatitis, grade Ⅲ radiation dermatitis only occurred 2 cases, noⅣgrade radiation dermatitis occurred. Comparison among the three groups, the difference was statistically significant (H=8.758,P<0.05). 3 groups of patients after treatment all suffered pain, 12 patients in triethanolamine cream group , 7 patients in lifuning group , only 2 cases in aloe vera gel group (H=8.586,P<0.05). The average cost of skin external used in 3 groups was different, triethanolamine cream group was 546.0 yuan, lifuning group was 458.2 yuan, and aloe vera gel group was 157.5 yuan. Among the three groups pairwise comparison, the differences in triethanolamine cream group and aloe vera gel group were statistically significant in pain (χ2=9.62,P<0.05), aloe vera gel group was better than the group of triethanolamine cream, the differences among radiation dermatitis grade, size and radiation dose of radiation dermatitis occurred the first time were not statistically significant (P>0.05). The difference between in lifuning group and triethanolamine cream group in pain had no statistically significant (χ2=2.47,P>0.05), other indexes had significant differences (P < 0.05). Lifuning was better than the triethanolamine cream to reduce and delay the onset and deterioration of radiation dermatitis and could prevent a widening of the area of radiation dermatitis;aloe vera gel group and lifuning group had a significant difference in radioepidermitis grade (χ2=6.32,P<0.05). Lifuning was better than the aloe vera gel and was more conducive to reduce and delay the occurrence of radiation dermatitis, other indexes differences had no statistically significant (P>0.05). Conclusions Considering the efficacy, pain and price three aspects which skin external use prevention and treatment radiation dermatitis patients with nasopharyngeal carcinoma, lifuning as the mixture of triethanolamine and aloe can effectively reduce and delay the chance of radiation dermatitis, reduce the radiation field experience of local pain, and affordable, the patients are more acceptable, it′s worthy of clinical use.

Effect of-berberine on reperfusion arrhythmias was studied using a 10 rain left anterior descending coronary artery occlusion followed by reperfusion in the isolated rat heart. Berberine, when given 10min before coronary ligation, reduced the incidence of reperfusion arrhythmias in a dose-riependent manner. With 10-5, 3. 16?10-5 and 10-4 mol/L of berberine, ventricular fibrillation was reduced from its control incidence of 100% to 90%, 70% and 40% (P

The experiment contents were integrated into three parts such as basic skills and verification experiment, systematic experiment and designing experiment. Basic skills and confirmato-ry experiments were performed alone with theory teaching by combination of modern teaching methods and traditional teaching methods, which consisted of “speaking”(experimental principles, methods and main technical points using multimedia), “looking”(demonstrating related operation on teaching website), teachers' demonstration, students' doing experiment independently and summarizing. In this part, the experimental operation skills such as the sterile operation technology, staining technology, microscopy technology and pure culture were emphasized. Systemic experiments would be carried out after completion of the most theory, the experiment time could be adjusted according to the experiment content, and the PBL teaching method was taken in this stage. After the theory teaching of Medical Microbiology was finished, students voluntarily participated in design experiments in the last stage, which were the fusion of scientific research subject and the experimental teaching. From the preview experiment, experiment operation, experiment report, to the final test, the multi-dimensional evalua-tion was implemented throughout the course of experiment teaching.

Objective To describe clinical features,polysomnographic (PSG) alterations and characteristics of motor and distribution during rapid eye movement (REM) sleep in narcoleptic patients with REM sleep behavior disorder (RBD).Methods We retrospectively summarized general features of 22 narcoleptic patients with RBD,96 narcoleptic patients without RBD and 21 healthy subjects as controls.We compared their PSG and the related indexes in 3 groups.Then we analyzed a full-night video-PSG recording in a continuous series in 22 narcoleptic patients with RBD to identify their motor behavior and distribution features.Results There was no significant difference in PSG parameter and correlation index between the narcoleptic patients with RBD group and without RBD group.However,compared with normal control group (20.15 ± 4.52),narcoleptic patients with or without RBD (24.07 ± 5.44,23.40 ± 4.50) showed increased the body mass index(F =4.869,P =0.009),shortened NREM sleep and REM sleep (min) latency at night (4.41 ±7.01,3.55 ±3.98 and 14.69 ±9.62,x2 =31.697,P =0.000;69.39 ±81.39,71.04 ±74.45and 115.31 ± 45.13,x2 =11.485,P =0.003),increased percentage of sleep stage 1,decreased percentage of slow wave sleep,delayed the arousal time and increased number of arousal episode longer than 5 minutes.In narcoleptic patients with RBD,RBD episodes occurred frequentlyatany stage of REM sleep through whole night and the frequency of vocalizations did not significantly differ between the two halves of the night.Pantomimes were significantly more frequent in RBD episodes of the second half of the night.Conclusions The prevalence of RBD is high in narcoleptic patients.Sleep architecture doesn' t differ between narcoleptic patients with and without RBD.There is no correlation between the occurrence of RBD and narcoleptic duration.In narcoleptic patients with RBD,vocalizations and pantomimes accounted formajor proportion of RBD episodes while aggressive-violent movements are rare.

Objective To investigate if atorvastatin is effective in reducing carotid intima media thickness (CA-IMT) in normocholesterolaemic patients with transient ischemic attack (TIA). Methods Forty-two patients with TIA were recruited. Patients were randomised to receive atorvastatin(5-10 mg/d) or placebo daily. Serum concentration of cholesterol and CA-IMT were measured before randomisation and at 6-and 18-month intervals. Results CA-IMT was significantly lower in atorvastatin group than that in placebo group at 18-month (P

Objective To explore the expression and function of galanin and its receptor in the female mice of anxiety-and depression-like behavior.Methods In situ hybridization was used to detect the expression of galanin,GalR1,GalR2 and GalR3 in the hippocampus of C57BL/6J female mice.A total of thirty female mice was divided into two groups:experiment group (n=15) and control group (n=15).The experiment group was subjected to the chronic unpredictable mild stress (CUMS) for four weeks,and the control group was not subjected to any treatment.Four weeks later,a series of tests were performed on those two groups,including the sucrose preference test,the novel object recognition test,the open field test and suspension tail test.After behavior tests,the hippocampus RNA was extracted from eight mice in each group to test the expression of galanin and its receptor through qPCR.The rest part of mice were used to mark C-Fos immunostaining in the dentate gyms (DG) of hippocampus.Results The result of in situ hybridization showed that galanin,GalR1 and GalR2 distributed in the Hillus of ventral hippocamous,GalR3 had no positive signal.In the sucrose preference test,the experiment group drunk less sucrose when compared with the control group (P＜0.05).In the novel object recognition test,the experiment group contacted shorter time to the novel object when compared with the control group (P＜0.05).In the open field test,the experiment group had shorter in session time when compared with the control group (P＜0.05).In the suspension tail test,the experiment group had longer immobility time when compared with the control group (P＜0.05).The qPCR result showed that the higher expression of galanin and GalR1 in the hippocampus of experiment group (P＜0.05).More C-Fos positive cells in the DG of hippocampus of experiment mice were immunostained (P＜0.05).Conclusions Galanin,GalR1 and GalR2 mainly distribute in the Hillus of the ventral hippocampus.Galanin may be involved in the anxiety-and depression-like behavior of C57BL/6J through GalR1.

OBJECTIVE:To observe clinical efficacy and safety of exenatide combined with clomiphene citrate in the treatment of polycystic ovary syndrome with insulin resistance. METHODS:98 patients with polycystic ovary syndrome complicated with in-sulin resistance were randomly divided into control group (49 cases) and observation group (49 cases). Control group was given Clomiphene citrate capsule 50 mg orally,once a day,for 5 d+Metformin enteric-coated tablet with initial dose of 0.25 g orally, twice a day,adjusted to 0.50-0.75 g orally,twice a day,for 3 menstrual cycles. Observation group was given Clomiphene citrate capsule(usage and dosage same as control group)+Exenatide injection 5 μg subcutaneously,twice a day,adjusted to 10 μg subcu-taneously,twice a day,for 2 months. Clinical efficacies of 2 groups were observed as well as the levels of LH,FSH,LH/FSH and IR before and after treatment,ovulation and pregnancy of infertility patients after treatment. The occurrence of ADR was record-ed. RESULTS:Total response rate,ovulation rate and pregnancy rate of observation group were significantly higher than that of con-trol group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in the levels of LH,FSH, LH/FSH and IR between 2 groups (P>0.05). After treatment,the levels of LH,LH/FSH and IR in 2 groups were significantly lower than before,and the observation group was significantly lower than the control group,the levels of FSH in 2 groups was sig-nificantly higher than before,and the observation group was significantly higher than the control group,with statistical significance (P<0.05). There was no statistical significance in incidence of ADR between 2 groups(P>0.05). CONCUSIONS:Exenatide com-bined with clomiphene citrate shows significant therapeutic efficacy for polycystic ovary syndrome complicated with insulin resis-tance and can increase ovulation rate and pregnancy rate through improving insulin resistance,but doesn't increase the occurrence of ADR.
