Objective To investigate the factors influencing mood and sleep among special operation personnel,so as to provide evidence for the prevention and intervention of related issues.Methods A total of 600 special operation personnel during their special duty were enrolled by random sampling method.Basic information was collected by a general information questionnaire.Mood and sleep status were evaluated by self-rating anxiety scale(SAS),self-rating depression scale(SDS),and Pittsburgh sleep quality index scale(PSQI).Results Spearman correlation analysis showed that factors associated with anxiety were years of work experience(r=0.099,P=0.016),family residence(r=-0.153,P＜0.001),and sleep status(r=0.199,P＜0.001);the factors associated with depression were relationship with parents(r=-0.134,P=0.001),family residence(r=-0.144,P＜0.001),and sleep status(r=0.122,P=0.003);and the factors associated with sleep were age(r=0.088,P=0.031),years of work experience(r=0.079,P=0.049),and number of children(r=0.083,P=0.043).Binary logistic regression analysis showed that depression was not an influencing factor of sleep(odds ratio[OR]=1.302,95%confidence interval[95%CI]0.759-1.758,P=0.086),while anxiety was an influencing factor of sleep(OR=2.187,95%CI 1.608-4.695,P=0.001).Conclusion The sleep status of special operation personnel investigated in this survey is related to age and years of work experience,and is influenced by anxiety.Therefore,greater attention should be given to sleep issues in the occupational health support of special operations.Additionally,years of work experience,family residence,relationship with parents,and sleep status are related to anxiety and depression among special operation personnel.It is necessary to focus on the mental health of older workers and those with longer tenure.

OBJECTIVE: To compare the efficacy and safety of intravenous colistin sulfate combined with nebulized inhalation versus intravenous monotherapy for pulmonary infections caused by carbapenem-resistant organism (CRO). METHODS: A multicenter retrospective cohort study was conducted. Clinical data were collected from patients admitted to the intensive care unit (ICU) of 10 tertiary class-A hospitals in Henan Province between July 2021 and May 2023, who received colistin sulfate for CRO pulmonary infections. Data included baseline characteristics, inflammatory markers [white blood cell count (WBC), neutrophil count (NEU), procalcitonin (PCT), C-reactive protein (CRP)], renal function indicators [serum creatinine (SCr), blood urea nitrogen (BUN)], life support measures, anti-infection regimens, clinical efficacy, microbiological clearance rate, and prognostic outcomes. Patients were divided into two groups: intravenous group (colistin sulfate monotherapy via intravenous infusion) and combination group ((intravenous infusion combined with nebulized inhalation of colistin sulfate). Changes in parameters before and after treatment were analyzed. RESULTS: A total of 137 patients with CRO pulmonary infections were enrolled, including 89 in the intravenous group and 48 in the combination group. Baseline characteristics, life support measures, daily colistin dose, and combination regimens (most commonly colistin sulfate plus carbapenems in both groups) showed no significant differences between two groups. The combination group exhibited higher clinical efficacy [77.1% (37/48) vs. 59.6% (52/89)] and microbiological clearance rate [60.4% (29/48) vs. 39.3% (35/89)], both P < 0.05. Pre-treatment inflammatory and renal parameters showed no significant differences between two groups. Post-treatment, the combination group showed significantly lower WBC and CRP [WBC (×10⁹/L): 8.2±0.5 vs. 10.9±0.6, CRP (mg/L): 14.0 (5.7, 26.6) vs. 52.1 (24.4, 109.6), both P < 0.05], whereas NEU, PCT, SCr, and BUN levels showed no significant between two groups. ICU length of stay was shorter in the combination group [days: 16 (10, 25) vs. 21 (14, 29), P < 0.05], although mechanical ventilation duration and total hospitalization showed no significant differences between two groups. CONCLUSIONS Intravenous colistin sulfate combined with nebulized inhalation improved clinical efficacy and microbiological clearance in CRO pulmonary infections with an acceptable safety profile.

AIM:To investigate the therapeutic effect of menstrual blood-derived endometrial stem cells(MenSCs)on chemotherapy-induced intestinal mucositis and flora disorders in mice,and to explore the potential mecha-nism.METHODS:The mice were randomly divided into 3 groups including normal treatment,cisplatin(Cis)treatment and Cis+MenSC treatment,with 10 mice in each group.To induce intestinal mucositis,the mice were treated with Cis(2 mg·kg-1·d-1)by intraperitoneal injection for 5 consecutive days.Control mice for normal group were received equal vol-umes of normal saline.For Cis+MenSC treatment,MenSCs(1×106)was transplanted into the mice of Cis treated mice through tail vein.The performances and weight changes of mice were examined during the experiment.After the treat-ment,the small intestine and colon were isolated for subsequent HE staining,the ratio of F4/80 and IL-6 positive cells in small intestine were detected by immunohistochemical staining,and the expression of tight junction,inflammation and apoptosis related proteins was detected by Western blot.16S rDNA amplicon sequencing was performed to detect the diver-sity and richness of intestinal flora in mice.RESULTS:Compared to the Cis group,the MenSCs-treated mice showed sig-nificantly increased body weight,relieved intestinal lymphocytes infiltration,alleviated intestinal villous edema,and or-derly arranged glands in intestinal tissues.Further analysis indicated that MenSCs transplantation significantly up-regulat-ed the expression of intestinal tight junction related proteins ZO-1 and occludin in Cis-treated mice(P＜0.05).Subse-quently,MenSCs transplantation significantly inhibited the macrophages infiltration in intestinal tissues(P＜0.01),down-regulated the expression of pro-inflammatory factors IL-1 and IL-6 and pro-apoptotic protein Bax(P＜0.01),while up-regu-lated anti-inflammatory factor IL-10 and anti-apoptotic protein Bcl-2(P＜0.01).Additionally,further microflora sequenc-ing indicated that MenSCs transplantation prevented mice from Cis-induced intestinal flora disorder,and significantly re-duced the abundance of harmful bacteria such as isenbergiella tayi and Anaerotruncus colihominis(P＜0.01).At the same time,the abundance of beneficial bacteria Lactobacillus apodemi was increased(P＜0.05),thereby restoring the composi-tion and function of healthy intestinal flora.CONCLUSION:MenSCs transplantation alleviates the chemotherapy-in-duced damage of intestinal structure,relieves the symptoms of chemotherapy-induced mucositis and restores the homeosta-sis of intestinal flora in mice.

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 explore the intervention mechanism of Changzhou Tongbian Formula on functional constipation(FC)combined with depression in rats.Methods A rat model of FC combined with depressive-like behaviors was established by using gastric gavage of berberine hydrochloride and chronic unpredictable mild stress.The model rats were randomly divided into blank group,model group,lactulose group,and Changzhou Tongbian Formula high-,medium-,and low-dose groups,and the intervention was carried out for five weeks.The fecal water content was calculated before and after intervention.The small intestinal propulsion rate was calculated after intervention.The depressive-like behavior levels of rats were evaluated by forced swimming test and sucrose preference test before and after intervention.The colonic mucosal morphology was observed by HE staining.The morphology and number of pyramidal cells in the hippocampal CA1 and DG regions were observed by Nissl staining.The relative protein expression levels of the transient receptor potential vanilloid 4(TRPV4)in colonic tissue,as well as brain-derived neurotrophic factor(BDNF),tyrosine kinase receptor B(TrkB),mitogen-activated protein kinase(MAPK),and cAMP-response element binding protein(CREB)in the hippocampus of rats in each group were detected by Western Blot method.Results Compared with the blank group,the fecal water content of rats in the model group was significantly reduced(P＜0.001),the small intestinal propulsion rate was significantly lower(P＜0.01),the sucrose preference index was significantly decreased(P＜0.001),the number of pyramidal cells in the CA1 and DG regions of the hippocampus was significantly reduced(P＜0.001),and the TRPV4 in the colon and the BDNF,TrkB,MAPK,and CREB protein contents in the hippocampus were all significantly decreased(all P＜0.001).Compared with the model group,the fecal water content of the Changzhou Tongbian Formula high-,midium-,low-dose groups and the lactulose group were significantly increased(P＜0.001,P＜0.01).The small intestinal propulsion rate of the Changzhou Tongbian Formula high-,low-dose groups and lactulose group were significantly increased(P＜0.01,P＜0.05).The sucrose preference indices of the Changzhou Tongbian Formula high-,midium-,low-dose groups and lactulose group were significantly increased(P＜0.01,P＜0.05).There was no abnormality in the colonic histology.The numbers of pyramidal cells in the CA1 and DG regions of the hippocampus of the Changzhou Tongbian Formula high-,midium-,low-dose groups and lactulose group were significantly increased(P＜0.01,P＜0.001).The TRPV4 content in the colon of the Changzhou Tongbian Formula high-,midium-,low-dose groups and lactulose group were significantly increased(P＜0.001),and the BDNF,TrkB,MAPK,and CREB protein contents in the hippocampus were all significantly increased(P＜0.05,P＜0.01,P＜0.001).Conclusion After intervention,Changzhou Tongbian Formula can significantly improve the TRPV4 content in the colon of model rats with the comorbidity of FC with depression,increase the moisture content of feces,promote intestinal peristalsis and improve constipation.Meanwhile,TRPV4 can activate the BDNF/TrkB/MAPK pathway,trigger an increase in downstream CREB,improve neuroplasticity and thus alleviate some depressive-like behavior.

Purpose To explore the cardioprotective effect of cang-ai volatile oil(CAVO)on rats with cardiac function impairment model under low-pressure and low-oxygen environment in Tibet Plateau based on 7.0T cardiovascular magnetic resonance(CMR)imaging.Materials and Methods Forty SD rats were randomly divided into the normal group,the high altitude model group,the CAVO-treated group and the rhodiola rosea-treated group,with 10 rats in each group.Except for the normal group,the rats in other groups were transferred from the plain(500 m above sea level)to the Tibet Plateau(4 250 m above sea level)for two months,and then administered with the corresponding drugs by gavage for 14 d.The left ventricle function was measured by using a 7.0T high-field strength CMR and myocardial strain was analysed by using tissue tracing technique.HE staining was used to observe the morphology of cardiomyocytes,Masson staining to observe interstitial fibrosis,wheat germ agglutinin staining to observe cardiomyocyte hypertrophy,and transmission electron microscopy to observe the morphological changes of mitochondria in each group.Serum levels of creatine kinase,creatine kinase isoenzyme,lactate dehydrogenase,cardiac troponin T,superoxide dismutase,malondialdehyde and glutathione peroxidase were detected.Intracellular reactive oxygen species levels were detected using flow cytometry.Results The left ventricular ejection fraction of rats in the CAVO-treated group was higher than that of the high altitude model group[(66.61±1.38)％vs.(60.94±3.21)％;t=3.969,P=0.032];meanwhile,the global circumferential strain of the left ventricle in the CAVO-treated group was higher than that of the high altitude model group(-25.68±1.30 vs.-22.84±1.17;t=3.967,P=0.003).HE,Masson and wheat germ agglutinin staining showed hypertrophy and necrosis as well as interstitial fibrosis and ultrastructural disruption of cardiomyocytes in the high altitude model group,which improved after CAVO treatment.The level of cardiac troponin T in the serum of rats with CAVO treatment group was significantly decreased compared with that of the high altitude model group[(314.03±20.05)pg/ml vs.(518.30±18.13)pg/ml;1=13.090,P=0.001].Conclusion CAVO treatment can reduce cardiac injury caused by low-pressure hypoxia in high altitude,and its effect can be detected dynamically and non-invasively by 7.0T high-field strength CMR.
