Objective To study the effect of field long march comprehensive training on freshmen' mental quality and mental health in military university. Methods Mental quality questionnaire for army men (MQQA), symptom checklist 90 (SCL-90), self-rating anxiety scale (SAS), self-rating depression scale (SDS) and trait anxiety inventory (TAI) were carried out on 330 freshmen at various stages on their military training. All data were analyzed by paired-sample t test. Results ①As compared with pre-training, all SCL-90 factor scores except depression factor decreased significantly (P<0.05); compared to barracks military training, recruits revealed a decrease (P<0.05) in all SCL-90 factors except factors on fear, paranoia and mental disorder. ②The scores of SDS and SAS displayed a“V”shape as they decreased after the early rise at the course of military training. After the barracks military training, SAS and SDS scored high (P<0.01);Compared with pre-training, TAI scores dropped significantly (P<0.01) after field long march; compared with post barracks military traning results, SAS, SDS and TAI scores of recruits after field long march decreased significantly (P<0.05). ③After barracks military training and field long march comprehensive training, recuits' mental quality factors scored no significant distinction (P>0.05). Conclusion Filed long march effectively improved mental health of military university recruits and relived their anxiety as well as depression.

Objective To investigate the compliance and the self-efficacy of catheter maintenance in patients with PICC, convenience sampling methods were used to analyze the influence of the self-efficacy on compliance of catheter maintenance. Methods From January 2017 to July 2017, a total of 200 cases patients with PICC in the oncology department of the Second Affiliated Hospital of Nanchang University were selected. The general information, the self- efficacy and compliance of catheter maintenance were investigated. Results The self-efficacy of PICC catheter patients was positively correlated with the total score of catheter maintenance compliance, living habits, self-monitoring and cognitive behavior score (r=0.56-0.92, P<0.01), and it was linearly dependent with the total compliance of catheter maintenance, and the correlation coefficient of Pearson was 0.82. The self-efficacy, monthly income, education level, place of residence, complications and payment methods hadsignificant influence on the compliance of catheter maintenance (P<0.05), among which the self-efficacy had the greatest impact. Conclusions The self-efficacy of patients with PICC catheter is one of the essential factors in improving the compliance of catheter maintenance, and it can improve the compliance of catheter maintenance in PICC patients by looking for the self-efficacy of patients with PICC catheter.

Objective To observe the clinical efficacy and related complications of modified suture method in treating perimembranous ventricular septal defect(VSD). Methods The clinical data of 110 children with perimembranous VSD were retrospectively analyzed. Among them, 51 cases were treated with conventional suture method (conventional suture group), and 59 cases were treated with modified suture method(modified suture group).The extracorporeal circulation time,intraoperative blood transfusion volume, postoperative drainage volume, total hospital stay and related complications were recorded. The transthoracic echocardiography was performed 1, 6 and 12 months after operation. Results The children successfully completed the operation,and no intraoperative death occurred.The extracorporeal circulation time, intraoperative blood transfusion volume, postoperative drainage volume, total hospital stay and rate of related complications in modified suture group were significantly lower than those in conventional suture group: (41.2 ± 9.6) min vs. (52.1 ± 10.6) min, (182.2 ± 42.9) ml vs. (255.3 ± 56.7) ml, (73.2 ± 18.7) ml vs. (102.3 ± 23.5) ml, (12.8 ± 2.5) d vs. (16.1 ± 3.6) d and 13.6% (8/59) vs. 29.4% (15/51), and there were statistical differences (P<0.01 or <0.05). The blood flow velocity of pulmonary valve and blood flow velocity of aortic valve 1,6 and 12 months after operation in modified suture group were significantly better than those in conventional suture group, blood flow velocity of pulmonary valve: (113.8 ± 21.4) cm/s vs. (126.5 ± 22.6) cm/s, (104.6 ± 18.2) cm/s vs. (112.3 ± 18.5) cm/s, (102.3 ± 15.8) cm/s vs. (113.8 ± 16.5) cm/s; blood flow velocity of aortic valve:(141.9 ± 24.6)cm/s vs.(136.0 ± 25.7)cm/s,(148.3 ± 18.7)cm/s vs.(142.3 ± 20.3)cm/s,(148.8 ± 18.1) cm/s vs. (141.6 ± 18.1) cm/s, and there were statistical differences (P<0.05). Conclusions The modified suture method has the characteristic of short operating time, less blood transfusion and postoperative drainage,and swift recovery.It also can reduce postoperative arrhythmia and residual reflux.

Objective·To describe the level of multiple symptom distress and physical activity in children and adolescents with cancer,analyze symptom distress profiles,and explicit the relationship between latent profiles and physical activity.Methods·From November 2021 to March 2023,the convenient sample method was used to recruit children and adolescents with cancer aged 10-18 years old,who had been treated for more than 1 month in the Departments of Hematology/Oncology,Shanghai Children's Medical Center and Xin Hua Hospital,Shanghai Jiao Tong University School of Medicine.The questionnaires,including General Information Questionnaire,Memorial Symptom Assessment Scale 10-18(MSAS 10-18)and Modified Chinese Version of Children's Leisure Time Activities Study Survey(CLASS-C),were used.Latent profile analysis was used to identify whether the level of multiple symptom distress in children and adolescents with cancer was population heterogeneity and its explicit characteristics.Whether there were differences in physical activity levels among different profiles of symptom distress was also analyzed.Results· A total of 165 valid questionnaires were collected,with an effective response rate of 91.7％.The symptom distress scores of the top five occurrence rates of symptoms in children and adolescents with cancer were lack of energy with a median of 1(1,2)point,nausea 1(1,2)point,lack of appetite 2(2,3)points,sweat 1(1,2)point,and pain 1(1,2)point.The physical activity level of the patients was mainly light,with a median of 2 530.00(1 577.50,3 721.00)min/week,and moderate to vigorous physical activity was relatively lower[70.00(10.00,197.50)min/week].The patients with cancer could be divided into two latent profiles:"high fatigue-high nausea-high hair loss-high sleepy"and"high fatigue-low nausea-low vomiting-low sleepy",which were named as high symptom distress(n=47,30.6％)and low symptom distress(n=l 18,69.4％)separately.Multivariate Logistic regression analysis showed that patients with acute lymphoblastic leukemia were more likely to be classified as high symptom distress group,and outpatients in the latest hospital visit were more likely to classified as low symptom distress group(both P＜0.05).In addition,patients with high symptom distress had a higher level of light physical activity(P＜0.05),and had a lower level of moderate to vigorous physical activity,but the difference was not statistically significant.Conclusion·There is population heterogeneity in the multiple symptom distress in children and adolescents with cancer.Disease type(acute leukemia)and the way of the latest hospital visit(through outpatient department)are the predictors of symptoms profiles of patients with cancer.Patients who experience high symptom distress have higher level of light physical activity,and perhaps lower level of moderate to vigorous physical activity.

Objective:To investigate and analyze the basic occupational situation of Chinese radiotherapists and to provide references for the development and construction of the radiation therapist team in China.Methods:Between May 7, 2021 and June 15, 2021, this survey was conducted using a self-designed questionnaire, which was distributed and collected in the form of online survey to conduct a statistical analysis of the basic situation of radiotherapists in 30 provincial-level administrative regions in China.Results:A total of 2 928 valid questionnaires were collected from 30 provincial-level administrative regions. The ratio of male to female and average age of the participants were 69∶31 and 35 years (18-65), respectively. According to the survey result, 84.7% of the participants came from Tertiary A-level hospitals. In terms of educational background, the participants with doctoral, master, undergraduate, junior-college, and technical-secondary degrees accounted for 0.2%, 6.9%, 76.6%, 14.9%, and 1.4%, respectively. In terms of title, full senior technologists, associate senior technologist, technologist-in-charge, technologist, and technician in the participants accounted for 0.5%, 5.8%, 32.5%, 52.2%, and 8.2%, respectively. The participants with years of employment of 0-, 5-, 10-, 20-y accounted for 33.74%, 25.79%, 25.51%, and 14.96%, respectively. The majors of the participants included medical imaging/imaging technology (45.9%), clinical medicine (19.1%), and biomedical engineering (11.9%).Conclusions:Chinese radiotherapists tend to be younger and are rapidly increasing in number. Employers should attach importance to the career planningand continuing education of radiotherapists to improve their technical skills, in order to fully satisfy the demand for radiotherapists in the new era.

Objective:To investigate the risk factors of postpartum embryo residues associated with uterine arteriovenous fistula.Methods:From January 2000 to December 2020, 26 cases of postpartum embryo residue complicated with uterine arteriovenous fistula in Tangshan Maternal and Child Health Hospital were selected as the case group, and 32 cases of postpartum embryo residue without uterine arteriovenous fistula were selected as control group.Both the case group and the control group had embryo residue in cesarean scar.Univariate and multivariate logistic analysis were used to screen the risk factors of postpartum embryo residue combined with uterine arteriovenous fistula.Results:There were 26 patients in the case group, including 3 patients after medical abortion, 17 patients after artificial abortion, 2 patients after cesarean section, and 4 patients after mid-term induced labor.There were 32 patients in the control group, including 7 patients after medical abortion, 11 patients after induced abortion, 8 patients after cesarean section, and 6 patients after mid-term induced labor.There were 11 patients in the case group and 3 patients in the control group.Univariate analysis showed that: the occurrence of postpartum embryo residue combined with uterine arteriovenous fistula was related to the time of vaginal bleeding, HCG value before and after treatment, hemoglobin value before treatment, platelet count and residual embryo area(all P<0.05). Multivariate regression analysis showed that the increase of hCG before treatment ( OR 20.319, 95% CI 1.348-306.187) and the decrease of hemoglobin before treatment ( OR 0.870, 95% CI 0.788-0.960) were the independent risk factors of postpartum embryo residue combined with uterine arteriovenous fistula (all P<0.05). Conclusion:The risk factors of uterine arteriovenous fistula in postpartum embryo residue patients with elevated hCG value and decreased hemoglobin value before treatment should be highly vigilant to reduce the rate of clinical missed diagnosis.

Objective To explore the related factors of severe infectious diarrhea in hospitalized pediatric patients with leukemia, and to suggest preventive nursing countermeasures. Methods Totally 81 pediatric patients, which were diagnosed with infectious diarrhea in hospitalized pediatric patients with leukemia in Shanghai Children′s Medical Center from July 2016 to December 2017,were collected and analyzed. Univariate analysis and multivariate Logistic regression analysis was carried out on the related factors affecting severe infectious diarrhea. Results There were 36 cases (44.4%) of severe infectious diarrhea occurred in 81 patients with infectious diarrhea. Multivariate Logistic regression analysis showed that the history of diarrhea ( OR=3.887) and the long duration of diarrhea with neutropenia ( OR=1.243) were risk factors for severe infectious diarrhea in hospitalized children with leukemia (P<0.05). And the results also showed that the bigger age ( OR=0.799) and the newly diagnosed leukemia ( OR=0.236) were the protective factors for severe infectious diarrhea in in hospitalized children with leukemia (P<0.05). Conclusion Prevention and treatment of diarrhea should be emphasized in pediatric patients with leukemia since newly diagnosis, and bone marrow depression should be actively ameliorated. Among those patients, smaller age and patients with repeated chemotherapy were at high risk for severe infectious diarrhea, which should be paid more attention.

Objective To explore the mental health status and characteristics of professional degree postgraduates.Methods 326 professional degree postgraduates from 3 universities were selected as subjects by cluster sampling.Symptom checklist 90 (SCL-90) was applied to assess psychological health of the postgraduates in order.Results 1) The positive rate of psychological symptom screening was 11.11％.The detection rate of psychological problems from high to low was:obsessive-compulsion,interpersonal sensitivity,depression,hostility,somatization,paranoid ideation,anxiety,phobic anxiety and psychoticism.2) Excluding the factors of phobic anxiety,there was significant age difference in each factor score and total score of SCL-90 (P＜0.05).The somatization,interpersonal sensitivity,anxiety,hostility,paranoid ideation,psychoticism factor scores and total score of the "≥30 years" group was significantly higher than those of "≤24 years"and the "25-29 years" group (P＜0.05),the depression factor scores of "≥ 30 years" was significantly higher than the "≤24 years" group (P＜0.01).3) The scores of somatizations (P=0.038) and obsessive-compulsive factors (P=0.043) of doctoral students were significantly higher than those of master students.4) In different grades,there were significant differences in the scores of obsessive-compulsives,depression,anxiety,hostility,paranoid ideation factor scores and SCL-90 total score (P＜0.05).The factor scores and total score of the Grade Three were significantly higher than those of the first grade (P＜0.05),and the scores of hostilities,paranoid ideation factors and total score were significantly higher than those of the second grade (P＜0.05).5) Excluding phobic anxiety,the factor scores and total score of SCL-90 in the "peace and tranquility" group were significantly lower than those of "quarrel" group (P＜0.05).6) Except for somatization and paranoia ideation,the factor scores and total score of SCL-90 of caring group were significantly lower than those non-caring group (P＜0.05).Conclusion The psychological health of graduate students of professional degree varies with age,educational level and grade,and is influenced by collective atmosphere and mentor attitude.The differences in the characteristics of the crowd should be taken into full consideration in the mental health education of colleges and universities,and the educational model should be explored,the educational goals,contents and forms should be refined to improve the mental health level of the population.
