ABSTRACT
【Objective:】 To explore the network structure characteristics and core items of meaning in life and coping styles among college students, and provide a basis for understanding their relationships and related interventions. 【Methods:】 A survey was conducted among college students using the Simplified Coping Style Questionnaire and Meaning in Life Questionnaire . The network analysis method was used to construct a network of college students’ meaning in life and coping styles, and R software was used for statistical analysis and visualization. 【Results:】 In the network of college students’ meaning in life and coping styles, "believing that time will change the status quo, and the only thing to do is to wait" and "trying to forget the whole thing" had the closest connection. "Learning from others to handle similar difficult situations" had the highest expected impact. "Seeking the meaning in life" and "pursuing hobbies and actively participating in cultural and sports activities" had the highest bridge expected influence. The average predictability value of all nodes was 0.775. 【Conclusions:】 Interventions aimed at "learning from others to handle similar difficult situations", "changing one’s own ideas and rediscovering what is important in life" and "changing some of the original practices or problems" may maximize the coping effect of college students. "Seeking the meaning in life" can furthest influence the coping styles, and "pursuing hobbies and actively participating in cultural and sports activities" can maximize the improvement of meaning in life.

ABSTRACT
Objective:The study seeks to explore the factors influencing the psychological status and sleep quality of medical workers amid the ongoing COVID-19 pandemic, in order to provide data sources and theoretical basis for the development of relevant psychological intervention programs.Methods:Employing the convenience sampling method, general information questionnaire (age, gender, marital status, educational background, job status, etc.), Generalized Anxiety Disorder-7 and Patient Health Questionnaire, epidemic stress index scale, and sleep quality questionnaire were distributed to medical staff between February 18 and April 3, 2020, using the PEM mental health care platform of by ZhongShengKaiXin for medical staff issued. Descriptive, single factor, and correlation analyses, as well as multiple linear regression analysis were used to analyze the data.Results:Overall, 24, 845 questionnaires were collected from 23 provinces, of which 24, 687 were valid, with a recovery rate of 99.36%. The findings showed that the proportion of medical personnel with symptoms of anxiety and depression was 50.58% and 51.37%, respectively; 16.11% had poor or very poor anti-stress ability; and 71.78% reported poor or very poor sleep quality. There was a positive correlation between anxiety, depression, anti-stress ability, and sleep quality ( P<0.05). Anxiety was positively correlated with depression, stress tolerance, and sleep quality( r=0.787, 0.667, and 0.486, all P<0.001); depression was positively correlated with stress tolerance and sleep quality ( r=0.709 and 0.586, both P<0.001); and stress tolerance was positively correlated with sleep quality ( r=0.452, P<0.001). Multiple linear regression analysis results showed that age, gender, marital status, educational background, professional title, job status, and participation influenced the anxiety levels of medical personnel in the backdrop of the pandemic ( P<0.001). Depression levels of medical staff were influenced by gender, educational background, job position, and participation ( P<0.001), while gender, marital status, educational background, job position, and participation influenced the stress tolerance levels ( P<0.001). The sleep quality of medical workers was influenced by age, gender, job position, participation in the fight against the pandemic, and professional title ( P<0.001). Conclusions:Amid the ongoing COVID-19 pandemic, medical staff reported poor mental health status and sleep quality, which can be attributed to diverse factors. The research findings can be useful for assisting medical staff to strengthen their self-cognition, while also providing certain psychological counseling data and theoretical basis for management departments.
ABSTRACT
Objective To explore the practical value of Stroop task of symptomatic words and identity-related words for screening executive dysfunction in schizophrenia.Methods Sixty-five patients with schizophrenia in clinical remission and sixty-two healthy controls were recruited in this trial.Patients and controls completed the Stroop task of symptomatic words and identity-related words.Analyze and compare the difference of reaction time between the two groups on the two stroop paradigms and further analyze the degree of discrimination of the two stroop paradigme.Results The reaction time of schizophrenic patients was longer than that of healthy controls in both symptom-word Stroop task ((1 206.65 ± 476.39)ms vs (916.01 ± 395.85) ms,t =6.46,P＜ 0.001),and identity-word Stroop task ((1 256.22 ± 630.18) ms vs (927.85 ± 419.98) ms,t=6.01,P＜0.01).The sensitivity and specificity were obtained by Receiver Operating Characteristic curves in symptom-word Stroop task (89％ and 57％,respectively) and identity-word Stroop task (81％ and 66％,respectively).Conclusion Symptom-word Stroop task and identity-word Stroop task showed moderate diagnostic value for the identification executive dysfunction in patients with schizophrenia.
ABSTRACT
Objective To assess the mid-term and long-term efficacy of the permanent inferior vena cava filter in the treatment of deep vein thrombosis of lower limb and discuss the clinical significance of inferior vena cava filter.Methods Retrospectively analyze on the 86 cases with deep vein thrombosis of lower limb (41 males and 45 females,aged 50 to 94 years,mean age was 71.8 years) treated with implantation of permanent inferior vena cava filter in inferior vena cava from Janunary 2010 to October 2015.In these patients,there were 51 cases with embolism in the left leg,25 cases in the right leg,10 cases in both legs and 6 cases were accompanied with pulmonary embolism.The cases without contraindication underwent catheter directed thrombolysis and even percutaneous transluminal angioplasty or stents subsequently if necessary after inferior vena cava filter implantation.All the cases with no contraindication were treated with anticoagulant therapy.Results All the 86 patients were implanted inferior vena cava filter (B.Braun Vena Tech LP 76 and Cordis TrapEase 10)successfully.Sisty-five cases were underwent inferior wena cava filter implantation only,while 21 cases were treated with inferior vena cava filter implantation and catheter directed thrombolysis or even percutaneous transluminal angioplasty and stents.During the follow-up period(12 to 81 months,mean time was 51 months),27 patients died dueing to malignant tumor(17 cases) and other diseases (10 cases) rather than complications caused by inferior vena cava filter.Three patients had recurrence of deep vein thrombosis and 2 patients suffered from the thrombosis induced by stenosis of stents.Inferior vena cava filter appered tilted with angle less than 15 degrees in 6 cases.Three cases suffered from new thrombosis below the filter and 2 cases complained of the filter migration.No case was found with fracture of filter,perforation of the inferior vena cava,bleeding or pulmonary embolism(new onset or recurrent).Conclusions Application of permanent inferior vena cava filter may cause complications,though it is an effective approach to prevent pulmonary embolism in patients with deep vein thrombosis of lower limb.However,permanent inferior vena cava filter may be fit for patients with old age,incurable cancer or limited expected life.
ABSTRACT
Objective To systematically assess the efficacy of the low-frequency repetitive transcranial magnetic stimulation (rTMS) to the right frontal cortex for depression. Methods Clinical randomized controlled trials (RCT) studies about low-frequency rTMS to the right dorsolateral prefrontal cortex (DLPFC) for depression were collected from database such as PubMed, SCI, CBM, CNKI, and VIP. The meta-analysis using the software of RevMan 5.2 was conducted to com?pare the response rate of low-frequency rTMS to the right DLPFC with sham stimulation and high-frequency rTMS to the left DLPFC, respectively. Results Nine RCT studies with 156 patients in low-frequency rTMS group and 162 patients in sham stimulation group were included. Meta-analysis showed that low-frequency rTMS to the right DLPFC significantly improved response rate compared with sham stimulation(RR=2.15,95%CI:1.57~2.95,P<0.01). Eleven RCT studies with 178 patients in low-frequency rTMS group and 200 patients in high-frequency group were included. There was no significant difference in response rate between the two groups(RR=0.80,95%CI:0.63~1.02,P=0.07). Conclusion The efficacy of low-frequency rTMS to the right frontal cortex for depression is significant but the efficacy is not superior in comparison with the high-frequency rTMS to left DLPFC.
ABSTRACT
Objective To explore the mechanism of drug resistance of ovarian cancer cells to TRAIL-induced apoptosis.Methods We collected 3AO cells and CAOV3 cells,respectively,at 18,24,48 and 72 hour under 12.5,25,50 and 100 ng/mL concentrations of TRAIL.The rate of cell growth inhibition was checked by methyl thiazolyl tetrazolium (MTT)assay to evaluate the effect of TRAIL.Morphology of apoptotic cells was observed by TdT-mediated-dUTP nick end labeling (TUNEL).The apoptosis rate was detected by flow cytometry (FCM)and C-FLIP protein was determined by Western blotting.Results TRAIL inhibited the growth of 3AO and CAOV3 cells.The rate of growth inhibition at 24 hour was 28% in 3AO cells and 10% in CAOV3 cells.TRAIL induced apoptosis of cells.The apoptosis rate at 24 hour was 8.5% in 3AO cells,which was higher than 5.5% in CAOV3 cells.The expression level of C-FLIP protein was higher in CAOV3 cells than in 3AO cells.Conclusion C-FLIP protein is an important protein that regulates drug resistance of ovarian cancer cells to TRAIL-induced apoptosis.
ABSTRACT
Objective To explore the relationship between schizotypal personality proneness and intelligence .Methods 1905 subjects were tested by Chinese Soldier Personality Questionnaire(CSPQ).According to the results of CSPQ,the subjects were divided into high-risk subjects and normal ones.The Words Reasoning Test, the Arithmetic Reasoning Test and the Assembling Test were used to evaluate the intelligence,and the scores of these tests were compared between the two groups.Correlation coefficient between schizotypal personality proneness and intelligence was calculated.Results The scores of the Words Reasoning Test,the Arithmetic Reasoning Test and the Assembling Test in high-risk subjects were significantly lower than those in normal ones((87.83±18.42)VS(101.37±13.48),P<0.01;(91.74±14.26)vs(101.65±14.62),P<0.01;(87.70±18.82)VS (101.73±14.26),P<0.01).Schizotypal personality proneness was significantly correlated with the scores of intelligence(r=-0.39,P<0.01).Conclusion Lower intelligence level is found in the group with schizotypal personality proneness.Intelligence is correlated with schizotypal personality proneness.
