Objective To investigate the mental health and influencing factors of naval officers and soldiers,and provide data support for formulating effective psychological intervention measures.Methods The 12-item general health questionnaire(GHQ-12)was used to conduct a sample survey among 5 336 naval officers and soldiers from October to November 2021.SPSS 26.0 software,chi-square test and regression analysis were used for descriptive statistics.Results A total of 5 102(95.61%)valid questionnaires were collected.The average GHQ-12 score was 0.55±1.18,and the proportion of high-risk individuals for mental health was 3.06%.Chi-square test showed that there were significant differences in the distribution of mental health status among interviewees with different ages,education levels,marriage status,family economy,family relationship,growing family,history of mental diseases among close relatives,major changes encountered during growth,hobbies and specialties,recent work pressure and recent interpersonal relationship(P≤0.001).Regression analysis showed that age(P=0.006),family relationship(P<0.001),family economy(P=0.010),major changes encountered during growth(P<0.001),recent work stress(P<0.001)and recent interpersonal relationship(P<0.001)were main influencing factors for mental health of naval officers and soldiers.Conclusion The mental health of naval officers and soldiers was generally good,but some individuals still have mental health problems,which are affected by many factors.It is necessary to pay more attention to the mental health problems caused by their age,education,family,growth experience,stress and interpersonal relationship.

Objective To investigate the current status and influencing factors of mental disorders in working women in psychological clinic of a first-class hospital in Shanghai,so as to provide guidance for prevention and treatment of this disease.Methods A cross-sectional survey was conducted on 122 working female patients from the psychological clinic of a first-class hospital in Shanghai.Mental health status was assessed by General Situation Scale,Self-Efficacy Scale,Patient Health Questionnaire-9(PHQ-9),Generalized Anxiety Disorder-7(GAD-7),Yale-Brown Obsessive-Compulsive Scale(Y-BOCS),Hypomania Checklist-32(HCL-32),Patient Health Questionnaire-15(PHQ-15),AIS scale,and individual interviews.Descriptive statistics,non-parametric test,and multivariate logistic regression analysis were used to investigate the influencing factors of mental disorders in working women.Results The scores of anxiety,depression,compulsion,bipolar disorder,somatization symptoms,and insomnia were 12.02±4.29,14.91±5.53,6.09±5.71,7.28±5.25,13.54±6.29,and 10.79±5.27,respectively.Mild anxiety(36.1%),moderate depression(36.1%),and severe somatization(39.4%)were very common in these patients.Additionally,compulsive behaviors were found in 18.0%of the patients,bipolar disorder in 22.1%,and insomnia in 68.0%.Five factors(such as work hours)were related to anxiety(all P<0.05).Six factors(such as education level)were related to depression(all P<0.05).Seven factors(such as workplace relationships)were related to compulsions(all P<0.05).Age and four other factors were related to bipolar disorders(all P<0.05).Career development and three other factors were related to somatization(all P<0.05).Insomnia was significantly influenced by overtime work and five other factors(all P<0.05).Multivariate logistic regression analysis indicated that bad job stability and two other factors were risk factors for anxiety(all P<0.05),low self-efficacy and two other factors were risk factors for depression(all P<0.05),bad workplace relationships and two other factors increased compulsive behaviors(all P<0.05),more housing expenses increased bipolar disorders(P<0.05),more overtime aggravated somatization(P<0.05),and long working hours and two other factors worsened insomnia(all P<0.05).Conclusion Mental disorders in working women have become a common social issue,and are mainly influenced by individual factors(age,marital status,education level,housing expenses,and self-efficacy)and work-related factors(industry type,work hours,overtime,workplace relationships,job stability,career development,and corporate focus on female employees).Effective interventions from personal,corporate,and social perspectives are the key to preventing and treating mental disorders in working women.

Objective:To investigate the differences in cerebral oxygen metabolism in healthy volunteers at three altitude areas by MR quantitative magnetic susceptibility imaging (QSM) combined with three-dimensional arterial spin labeling (3D-ASL).Methods:From March 2019 to October 2020, Zhengzhou Han Chinese volunteers recruited from the First Affiliated Hospital of Zhengzhou University, Xining Han Chinese volunteers recruited from the Fifth People′s Hospital of Qinghai Province, Lhasa Han Chinese volunteers and Tibetan volunteers recruited from Lhasa People′s Hospital were collected. They were divided into 21-30 age group, 31-40 age group, and 41-50 age group. All the volunteers underwent MR QSM combined with 3D-ASL sequence imaging, and oxygen extraction fraction (OEF) and cerebral blood flow (CBF) images of gray matter, and white matter were collected, OEF and CBF values were obtained, and cerebral metabolic rate of oxygen (CMRO 2) values were calculated. The comparison of various indicators among multiple groups was conducted using one-way ANOVA, and pairwise comparisons were conducted using LSD- t test. Results:A total of 132 volunteers were included, including 38 Han Chinese volunteers in Zhengzhou, 9 in the 21-30 age group, 13 in the 31-40 age group and 16 in the 41-50 age group; 27 Han Chinese volunteers in Xining, including 9 in the 21-30 age group, 8 in the 31-40 age group and 10 in the 41-50 age group; 34 Han Chinese volunteers in Lhasa, including 13 in the 21-30 age group, 11 in the 31-40 age group and 10 in the 41-50 age group; and 33 Tibetan volunteers in Lhasa, including 10 in the 21-30 age group, 10 in the 31-40 age group and 13 in the 41-50 age group. In the group aged 21-30 years, the overall difference in brain gray matter OEF values among volunteers from different altitudes was statistically significant ( P<0.05), with statistically significant differences in OEF values between Tibetans in Lhasa and Han Chinese in Xining, Han Chinese in Lhasa ( P<0.05). The overall difference in CMRO 2 values in the gray matter of volunteers at different altitudes was statistically significant ( P<0.05), with significant differences in CMRO 2 values between Lhasa Tibetan and Han Chinese in Zhengzhou, Han Chinese in Xining, Han Chinese in Lhasa ( P<0.05). In the 31-40 age group, there were statistically significant differences in the overall CBF values of gray and white matter among volunteers from different altitudes ( P<0.05). Among them, there were statistically significant differences in the CBF values of gray and white matter between Han Chinese in Zhengzhou and Han in Xining, Han Chinese in Lhasa, Lhasa Tibetan ( P<0.05). The overall differences in OEF values of gray matter and white matter among volunteers at different altitudes were statistically significant ( P<0.05). Among them, there were statistically significant differences in OEF values of gray matter and white matter between the Han Chinese in Zhengzhou and the Han Chinese in Xining, the Han Chinese in Lhasa ( P<0.05). There was also a statistically significant difference in OEF values of gray matter and white matter between the Han Chinese in Lhasa and the Tibetan in Lhasa ( P<0.05). The overall difference in CMRO 2 values in gray and white matter among volunteers from different altitudes was statistically significant ( P<0.05). Among them, there was a statistically significant difference in CMRO 2 values of cerebral gray matter between Lhasa Tibetans and Zhengzhou Han, Xining Han, Lhasa Han ( P<0.05), and there was a statistically significant difference in CMRO 2 values of cerebral white matter between Lhasa Tibetans and Zhengzhou Han, Lhasa Han ( P<0.05). Conclusions:The cerebral oxygen metabolism of Tibetan living in the plateau is characterized by low oxygen consumption, low blood oxygen dependence and high tissue oxygen utilization. The CMRO 2 of the Han people who migrated to the plateau for a long time is maintained at a certain level, similar to that in the plain area. The effects of age factors on CBF, OEF and CMRO 2 are small.

Objective To investigate the dose of docetaxel appropriate for patients with metastatic castration-resistant prostate cancer and its affects to the prognosis.Methods A retrospective analysis was performed on the clinical data of 75 patients with metastatic castration-resistant prostate cancer admitted from March 2010 to July 2016 who received docetaxel combined with prednisone chemotherapy.The patients were divided into the low-dose group (n =43,docetaxel ＜ 65 mg/m2),the middle-dose group (n =21,docetaxel 65-70 mg/m2) and the high-dose group (n =11,docetaxel ＞ 70 mg/m2).The median age in the low-dose group,middle-dose group and high-dose group was 67 (53-80),66 (56-78) and 61 (47-76) years old,respectively.Among 75 patients with bone metastasis,2 patients had no evidence of bone metastasis in the low-dose group.The lymph node metastasis was found in 26,13 and 6 cases in each group,respectively.And visceral and other metastasis were founded in 11,4 and 2 cases,respectively.The Gleason score in the low-dose group was≤7 points in 15 cases,≥8 points in 22 cases and no score in 6 cases.The Gleason score inthe middle-dose group was ≤7 points in 4 cases,≥8 points in 13 cases and no score in 4 cases.The Gleason score in the high-dose group was ≤7 points in 3 cases,≥8 points in 5 cases and no score in 3 cases.The number of patients with pain in the low-dose group,middle-dose group and high-dose group was 36,12 and 9,respectively,there were no significant differences in the above indicators (P ＞ 0.05),except age,which showed relatively more aged patients in the low-dose group,(P =0.045).Kaplan-Meier method was used to compare the overall survival (OS),progression-free survival (PFS) and the incidence of ≥CTCAE-4 grade 3 adverse reactions between the two groups.The Cox regression model was adopted to analyzed the factors that might affect patient prognosis,including the effective time of first-line endocrine therapy,hemoglobin level,ECOG score,pain score,number of cycles of chemotherapy,age,dose of docetaxel and alkaline phosphatase (ALP).Kaplan-Meier method was used to analyze the effect of dose of docetaxel on the prognosis,and log-rank method was used to test the significance of the results.Results The median OS was respectively 24.1,18.5 and 23.5 months in the low-dose group,middle-dose group and high-dose group,respectively.The median PFS was 5.3 months in all three groups,which didn't show statistically significant differences.The incidence of grade 3/4 adverse reactions in the low-dose group,middle-dose group and high-dose group was 15 cases (34.9％),8 cases (38.1％) and 5 cases (45.5％) respectively.It showed an increasing trend,but no statistically significant difference.The single factors related to OS mainly include the effective time of first-line endocrine therapy,hemoglobin level,ECOG score,pain score,number of cycles of chemotherapy,there was no significant correlation with age,docetaxel dose,ALP and PSA value.Conclusions It is common to receive lower doses of docetaxel in clinical practice for patients with metastatic castration-resistant prostate cancer in China.The efficacy of low-dose docetaxel is similar to that of high doses (standard dosage).There was no significant correlation between the OS and the actual dose of docetaxel in the tolerable range.

Objective To improve the imaging diagnosis and differential diagnosis of non-epithelial ovarian tumor.Methods 34 patients with non-epithelial ovarian tumor confirmed by pathology were analyzed retrospectively.The image features of each patients were analyzed and compared with surgical pathology.Results The results exhibited 13 cases of teratoma,6 cases of ovarian granulosa cell tumor, 6 cases of ovarian fibroma, 5 cases of thecoma, 2 cases of dysgerminoma,and 2 cases of endodermal sinus tumor.All kinds of non-epithelial ovarian tumors had its imaging manifestations and clinical features.Conclusion Non-epithelial ovarian tumors have certain characteristic CT and MR performance,and combining the onset age,clinical symptoms and biochemical examination,can make the qualitative diagnosis.

Objective To evaluate the efficacy and safety of the modified docetaxel plus prednisone scheme for the metastatic castration resistant prostate cancer patients who got poor tolerance to chemotherapy.Method The clinical data of 50 metastatic castration resistant prostate cancer who received docetaxel + prednisone chemotherapy from March 2010 to October 2015 were analyzed retrospectively.23 cases received the modified DP regimen (modified group),27 cases received the standard DP regimen (standard group).The median age of the modified group and the standard group were 69 years (47-80 years) and 63 years (52-77 years) (P =0.005).There were 19 and 24 cases with pain in modified group and standard group respectively;10 and 19 cases with lymph node metastasis respectively;3 and 4 cases of visceral metastasis respectively;all of the 50 patients were complicated with bone metastasis.For the pathological Gleason score,there were 7 cases scored ≤7 points,13 cases scored ≥ 8 points and 3 cases unscored in the modified group;7 cases scored ≤7 points,15 cases scored ≥8 points and 5 cases unscored in standard group.There was no significant difference of the pain,metastasis,and Gleason score between the two groups (P ＞ 0.05).Progression free survival (PFS),overall survival (OS)and adverse events were analyzed using Kaplan-Meier curves,and the differences were assessed using the log-rank test.Results In the modified group and standard group,the median follow-up times were 11.0 months and 14.0 months respectively,the median chemotherapy cycles were 4.5 cycles and 5.0 cycles respectively;OS were 18.0 months and 27.5 months respectively (P =0.746).The PFS of the two groups were 6.0 months and 5.2 months,respectively (P =0.822).The PSA response were 13 cases and 17 cases in the modified group and standard group respectively (P =0.615),and the pain response were 8 cases and 7 cases (P =0.927),grade 3 to 4 adverse events were 3 cases and 14 cases (P =0.003).The main adverse events were blood toxicity,neutrophils,gastrointestinal reaction,edema,fatigue and oral mucositis etc.Conclusions Compared with the standard DP scheme,the modified DP scheme had no significant difference in OS,PFS,pain response rate and PSA response rate,while the incidence of grade 3 to 4 adverse events was significantly reduced.Modified DP scheme may be a better choice for patients with metastatic castration resistant prostate cancer who get poor tolerance to chemotherapy.
