Objective:To explore the effectiveness of self-assisted couple communication program(SACCP)onprenatal depression and marital quality in pregnant women.Methods:Totally 90 pregnant women receiving ante-natal checkup in Air Force Medical Center with the Edinburgh Postnatal Depression Scale(EPDS)scores of ≥10 were voluntarily recruited and randomly allocated in routine caring and SACCP groups.Thirty-nine pregnant women in SACCP group and 37 pregnant women in routine caring group ultimately completed the study.In addition to rou-tine caring,the SACCP group completed a 10-week self-assisted family communication program once a week.The EPDS and Olson Marital Quality Questionnaires(ENRICH)were used as outcomes,and covariance and independ-ent t-teat were adopted to evaluate intervention effectiveness.Statistical analysis was conducted using the full analy-sis set and the per protocol set respectively.Results:Totally 76(84.4％)pregnant women received allocation and end-point revaluation.Covariance analysis revealed that EPDS adjusted means were higher in the SACCP group than in the routine caring group(P＜0.05)in both sets.T-test showed that marital satisfaction and couple communica-tion scores were higher in the SACCP group than in the routine caring group(Ps＜0.01)in the full analysis set.Conclusion:The self-assisted couple communication program(SACCP)could effectively alleviate clinical symptoms of prenatal depression of pregnant women and improve marital quality.

Objective:To investigate the predictive value of cerebroplacental ratio (CPR) for adverse perinatal outcomes of induction of labor in prolonged pregnancy.Methods:This retrospective study recruited 315 singleton pregnant women who had induced labor due to prolonged pregnancy (≥41 gestational weeks) in the First Affiliated Hospital of Chongqing Medical University from January 1, 2019 to April 30, 2020. Based on the occurrence of adverse perinatal outcomes (emergency delivery due to persistent abnormal fetal heart rate monitoring, umbilical artery blood pH at birth <7.2, 5 min Apgar scores<7, transferring to neonatal intensive care unit after birth, chorioamnionitis and vaginal delivery converted to cesarean section), they were divided into two groups: case group ( n=76) and normal group ( n=239). Clinical features and umbilical artery blood flow, middle cerebral artery (MCA) flow and CPR measured in the last ultrasound scan before induction were compared between the two groups using student's t-test, Mann-Whitney U test and Chi-square test. Receiver operating characteristic (ROC) curve was used to analyze the predictive values of umbilical artery blood flow, MCA flow and CPR for the adverse perinatal outcomes. Multivariate logistic regression analysis was used to screen the meaningful predictors. Results:Compared with the normal group, the umbilical artery pulsatility index (PI) (0.9±0.1 vs 0.8±0.1, t=-5.458, P<0.001) and the percentage of abnormal CPR (<1.0) increased significantly [21.1%(16/76) vs 6.3%(15/239), χ2=14.190, P<0.001] in the case group, while the MCA-PI and CPR decreased significantly (1.1±0.2 vs 1.3±0.3, t=5.658, P<0.001; 1.2±0.3 vs 1.6±0.5, t=8.940, P<0.001). The areas under the ROC curves of umbilical artery PI, MCA-PI and CPR for predicting adverse perinatal outcomes were 0.71, 0.71 and 0.77, respectively. CPR had the highest sensitivity (0.74) compared with umbilical artery PI (0.68) and MCA-PI (0.71), but the specificity of them were similar (0.67, 0.66 and 0.66). Multivariate logistic regression analysis showed that only CPR was the independent risk factor for adverse perinatal outcomes ( OR=0.028, 95% CI: 0.010-0.080, P<0.001). Conclusions:As an indicator for early prediction of adverse perinatal outcomes of induction of labor in prolonged pregnancy, CPR was more sensitive but less specific.

Objective:To explore the cognitive processing characteristics of semantic emotion Stroop and memory recognition in pilots with depression, and to systematically reveal the cognitive processing characteristics of attention and memory.Methods:The semantic emotional Stroop task and memory recognition test were performed in 36 depressed pilots and 36 healthy pilots.The results of attention and memory in cognitive processing were analyzed by repeated measurement analysis of variance using SPSS 18.0 software.Results:In the semantic emotion Stroop, the response time of the depression group was longer than that of the control group ( F(1, 70)=7.03, P=0.008), and the response time of the depression group(579.55±141.62)ms ) was longer than that of the neutral words (565.66±132.60)ms, P=0.003) and positive words (563.09±138.88)ms, P<0.01). In memory recognition, the accuracy of response to emotion words in the depressed group was higher than that in the control group ( F(1, 70)=23.15, P<0.01). The accuracy of response to negative words was higher in the depressed group than that to positive words ((0.50±0.32) vs (0.32±0.21), P=0.006) and neutral words ((0.50±0.32) vs (0.33±0.23), P=0.007). The depression group showed a conservative bias towards negative words ((1.46±0.40), P<0.01), and negative words compared with neutral words ((0.63±0.24), P<0.01) and positive words ((0.57±0.27), P<0.01) were cautious and conservative. Conclusion:Patients with depression have attention bias toward the negative information in semantic information processing, and negative memory bias in memory recognition.

Objective To evaluate the effect of Jinqiao-Reduqing granule in the treatment of children with herpes angina fever.Methods A total of 90 children with herpes angina were randomly divided into two groups,with 45 cases in each group.Both groups received the symptom-supported treatment.On this basis,the control group took ribavirin granules,while the observation group took Jinqiao-Reduqing granule.Both groups were treated for 4 days.The symptoms and signs were scored before and after treatment.The fever abatement time,herpes subsidence time,salivation disappearance time and appetite recovery time were observed and recorded.The serum levels of IL-2,IL-6,IL-10 and TNF-α were detected by ELISA,and peripheral blood levels of CD4+,CD8+,CD4+/CD8+ were detected by flow cytometry.Results After treatment,the scores of symptoms and signs in the observation group were significantly lower than those in the control group (3.02 ± 2.89 vs.6.88 ± 2.31;t=6.999,P＜0.01).The time of fever abatement (16.8 ± 3.2 h vs.29.9 ± 4.4 h,t=16.202),herpes subsidence (72.3 ± 5.4 h vs.96.7 ± 6.2 h,t=19.765),salivation disappearance (26.4 ± 2.0 h vs.46.3 ± 3.6 h,t=32.479) and appetite recovery (19.6 ± 4.2 h vs.39.7 ± 4.9 h,t=20.907) were significantly earlier than those in the control group (P＜0.01).After treatment,the serum levels of IL-2,IL-6,IL-10 and TNF-α in the observation group were lower than those in the control group (t were 4.974,4.410,6.447 and 4.767,respectively,all Ps＜0.01);CD4+ levels and CD4+/CD8+ were significantly higher than those in the control group (t were 4.033,6.860,all Ps＜ 0.01),and CD8+ levels was significantly lower than those in the control group (t=4.928,P＜0.01).Conclusions The Jinqiao-Reduqing granule can shorten the time of symptoms subsidence,reduce the level of inflammatory cytokines and improve the immunity of children with herpes angina fever.

Objective: To evaluate the immunogenicity of high-dose inactivated quadrivalent influenza serial vaccines (split virion) for elderly people. Methods: Immunogenicity assays on mouse as research animal model with inactivated quadrivalent influenza serial vaccines (split virion) were carried out. Then rates of seroconversion and geometric mean hemagglutination inhibition titers (GMTs) at day 21 after the last vaccination among those who received high-dose (HD) A+ B influenza vaccine, were compared with those who received other vaccines by hemagglutination inhibition (HAI) test. Results: The result of HAI test showed in HD serial vaccine groups, GMTs for all kinds of HA in the two HD serial vaccine groups were significantly different from that of the two SD serial vaccine groups, respectively (P<0.0001), but not the titers for A3 in one B dose first group. Further- more, GMTs for strain A in one B dose first groups were significantly higher than that of one B dose first groups in both HD and SD groups, and vice versa in the GMTs for strain B. The result of the assay of the impact of different immunization intervals of HD serial influenza vaccine on immunogenicity indicated that the immunity responses in 7 or 10 d groups were higher than that in 3 d group. Conclusions It is a new method to prevent the flu for elderly by HD A+ B serial influenza vaccine, whose HA dose per immunization was reduced into two injections, worked best when the immunization interval was 7-10 d. The protective immunity can be improved by selecting immune procedure of the serial vaccine according to the epidemic type surveillance of influenza virus A and B strains.

Objective: Quadrivalent influenza vaccines contain two lineages of type B virus, this study aimed to assess whether the result of single radial immunodiffusion (SRID) are accurate. The cross-interference of two type B hemagglutinins remains unknown. Methods: We detected the vaccine samples developed by Jiangsu GDK Biological Technology Co., ltd by SRID. Results: There was no significant difference between the HA content of antigen reagent, bulk sample and mixed sample of two B bulk within 10 to 40 μg/ml (P>0.05). Then each hemagglutinin B was diluted respectively by other three HA, 30 μg/ml, the other hemagglutinin B or phosphate buffer solution were measured within 10-160 μg/ml. Within 10-40 μg/ml, the HA content was proportional to the diameters of immunodiffusion (R²=0.998), while within the higher content range, a ternary linear regression equation fitted best (R²=0.999). Conclusions No cross-interference between B/Brisbane and B/Phuket was found in SRID within both detection ranges.

Objective To study the relationship between preoperative serum a-fetoprotein (AFP) level and early recurrence of patients with hepatocellular carcinoma (HCC) after partial hepatectomy.Methods 267 patients with hepatocellular carcinoma who underwent partial hepatectomy in Xijing Hospital,the Fourth Military Medical University from January 2011 to November 2015 were retrospectively studied.The patients were divided into the AFP-negative group (AFP ≤20 μg/L) and the AFP-positive group (AFP ＞ 20 μg/L) according to the preoperative serum AFP levels.The risk factors of early recurrence of HCC in patients after partial hepatectomy were studied by multivariate regression analysis.The recurrence-free survival rates during 24 months after surgery between the AFP-negative group and the AFP-positive group were compared.Results In 267 patients,97 patients had low or negative AFP levels (AFP≤20 μg/L) and 170 patients had high or positive AFP levels (AFP ＞ 20 μg/L).Patients in the AFP-positive group had significantly more well differentiated HCC on tumor histology when compared with patients in the AFP-negative group (x2 =17.050,P ＜ 0.05).The proportion of patients with liver cirrhosis in the AFP-positive group was significantly higher than that of the AFP-negative group (x2 =4.374,P ＜ 0.05).On the other hand,the numbers of patients with adjacent tissue invasion (x2 =4.374,P ＜ 0.05) and early HCC recurrence (x2 =7.595,P ＜ 0.05) in the AFP-positive group were significantly less than those of the AFP-negative group.Survival analysis showed that the recurrence-free survival rates in the AFP-positive and negative groups were 35.3％,52.6％,respectively.The results on univariate analysis showed that portal vein tumor thrombus,HBsAg positivity,tumor number,tumor diameter,tumor tissue differentiation,preoperative serum AFP level and adjacent tissue invasion were significantly associated with early recurrence of liver cancer (P ＜ 0.05).Cox multivariate regression analysis revealed that serum AFP positivity (HR =1.605,P ＜ 0.05),portal vein tumor thrombosis (HR =3.936,P ＜ 0.05),HBsAg positivity (HR =1.621,P ＜0.05),tumor diameter (HR =1.977,P ＜ 0.05) and tumor number (HR =1.991,P ＜ 0.05) were significantly correlated with early recurrence of liver cancer after partial hepatectomy.Conclusion The preoperative serum AFP level had an important predictive value for early recurrence of primary hepatocellular carcinoma in patients after partial hepatectomy.

Objective:To explore the prevalence rate of suicidal ideation and its risk and protective factors in military personnel.Methods:A total of 2071 military personnel were investigated by stratified random cluster sampling in May to August of 2015.The Question 7 of Beck Depression Scale (BDI) was used to test suicide ideation (item 7 score ≥ 1 was dovetailed in suicide ideation group).Family,social demographic and occupational factors were assessed with the self-made general characteristics questionnaire.The data were analyzed with multiple stepwise logistic regression.Results:There were 382 (18.4％) military personnel whose scores of item 7 were ≥1.Family history of suicide (OR =42.97,95％ CI =29.14-63.35),surrounding suicide (OR =2.46,95％ CI =1.75-3.46),drinking (OR =1.64,95％ CI =1.31-2.07) and level of education (OR =1.38,95％ CI =1.01-1.90) were risk factors of suicidal ideation.Protective factors were (OR =0.60,95％ CI =0.50-0.72) and station (OR =0.15,95％ CI =0.03-0.64).Conclusion:It suggests that in suicidal prevention for military,more attention is deserved paying to those military personnel who have family history of suicide,surrounding suicide,drinking habit,and are stationed in remote areas and air force.

Objective To observe the neural mechanism of learning and memory network disturbance induced by 36 hours sleep deprivation(SD).Methods 18 young male healthy volunteers were enrolled in this study.Resting state functional magnetic imaging(rs-fMRI) data was collected by blood oxygen level dependence functional magnetic imaging(BOLD-fMRI) during rest wakefulness(RW) and 36 hours SD.Bilateral hippocampus were selected as seed points by REST software automated anatomical labeling template.And then compared the differences of functional connectivity(FC) between bilateral hippocampus and whole brain regions by using paired-t test within statistical parametric mapping 8 (SPM8) software.Finally,correlation analysis had been done between significant FC of brain regions and WMS MQ values (SD-RW).Results Compared with RW,the bilateral hippocampus showed positive connected with the right dorsal posterior cingulate cortex,and showed negative functional connectivity with bilateral postcentral gyrus.The WMS MQ was significantly decreased after 36 hours SD.The connection between bilateral hippocampus and the right posterior cingulate cortex showed negative correlation with the deductionofWMS MQ (left:r=-0.463,P=0.015;right:r=-0.546,P=0.003).Conclusion SD has a significant effect on bilateral hippocampal FC.The FC between bilateral hippocampus and right dorsal posterior cingulate cortexis significant increased,while between bilateral postcentral gyrus is decreased after 36 hours SD.The former may be an important neurological mechanism in learning and memory ability regulation after 36 hours sleep deprivation.

Objective To explore the relationship between visuospatial abilities of the students ma-jor in air traffic management and their performances,and then provide theories of their vocational classified. Methods 104 healthy male college students were tested by the cognitive laterality battery (CLB),which included visuospatial tests and verbal-sequential tests.At the same time,their performances assessed by air traffic management stimulators.Results Subjects with higher scores achieved by operating on air traffic management stimulators have higher visuospatial abilities,which was confirmed by the visual spatial scores (A) ((0.183±0.094) vs (0.060±0.338), t=41.57, P=0.000) and cognitive laterality quotient (CLQ) ((0.087±0.108) vs (-0.096±0.101), t=43.14, P=0.000)).However,compared with others in lower scores group,their scores on the phonological tests (P) reduced ((0.096±0.081) vs (0.157±0.092), t=6.81, P=0.012) ) .Moreover,there were the significant positive correlation between their performance on air traffic management stimulators and A ( r=0.749, P<0.01) ,CLQ ( r=0.663, P<0.01) ,cognitive performance quotient (CPQ) ( r=0.394, P<0.01).Conclusion For air traffic management occupation,the higher visual spatial abilities were the base of having the higher performance.Thus the visuospatial abilities may be as a good index of selecting and vocational classified for air traffic management students.
