Objective:To explore the effects of depressive symptoms on sleep quality in adolescents with depressive disorder, and the mediating roles of cognitive fusion and sleep belief.Methods:A sample of 210 adolescents with first episode depressive disorder aged 12-18 years were recruited to complete 17-item Hamilton depression scale (HAMD-17), Pittsburgh sleep quality index (PSQI), cognitive fusion questionnaire (CFQ), and dysfunctional beliefs and attitudes about sleep scale (DBAS-16) from November 2021 to July 2022. SPSS 26.0 software was used to perform descriptive analysis and correlation analysis. The mediating effect was tested by Bootstrap analysis using PROCESS V 3.4 Macro program.Results:The incidence of low sleep quality in adolescents with depressive disorder was 69.0%(145/210). HAMD-17 score was (22.4±7.9), PSQI score was (9.7±3.7), CFQ score was (51.6±7.8), DBAS-16 score was (43.5±8.4).PSQI was positively correlated with the scores of HAMD-17 and CFQ( r=0.613, 0.463, both P<0.001).HAMD-17 was positively correlated with CFQ score ( r=0.488, P<0.001).DBAS-16 was negatively correlated with scores of PSQI, HAMD-17 and CFQ( r=-0.326, -0.284, -0.354, all P<0.001). The direct effect of depression on sleep quality was 0.230(95% CI=0.169-0.293). The indirect effect of depression on sleep quality through two pathways, the separate mediating effect value of cognitive fusion was 0.041 (95% CI=0.011-0.074), and the chain mediating effect value of cognitive fusion and sleep beliefs was 0.008(95% CI=0.001-0.020). Conclusion:Depressive symptoms can directly affect sleep quality of depressive disorder adolescents and indirectly through cognitive fusion and sleep beliefs.

Objective To analyze the efficacy and effects of balloon dilation combined with iliac vein balloon dilatation on complications and coagulation function of acute deep venous thrombosis of lower limbs(DVT)complicated with Cockett syndrome.Methods Data of 102 patients with acute DVT combined with Cockett syndrome admitted to the hospital from March 2018 to September 2022 were retrospectively analyzed,including 53 patients treated with catheter thrombolytic balloon dilation of iliac vein(recorded as the study group)and 49 patients treated with catheter thrombolytic therapy(recorded as the control group).Both groups were followed up for 1 year.Thrombosis clearance,edema reduction of affected limb,lower limb hemodynamics,coagulation function,peripheral blood inflammatory factors,complications and thrombosis recurrence were compared between the two groups.Results The thrombus removal grade of the study group was better than that of the control group(P＜0.05).Before and 1 year after surgery,In the control group,the leg circumference diameter difference above the knee between the affected side and the healthy side was(8.02±1.41)cm and(2.89±0.32)cm,respectively.In the study group,the data were(8.19±1.38)cm and(2.57±0.29)cm,respectively.Before and 1 year after surgery,in the control group,the leg circumference diameter difference below the knee between the affected side and the healthy side was(6.84±1.18)cm and(2.13±0.38)cm,respectively.In the study group,the data were(6.63±1.09)cm and(1.76±0.32)cm,respectively.The difference was statistically significant(P＜0.05),and the study group was lower 1 year after surgery(P＜0.05).The average blood flow velocity of femoral vein in control group was(24.75±4.03)cm/s and(28.82±4.29)cm/s before and 3 days after surgery,respectively.In the study group,the data were(24.02±3.86)cm/s and(30.94±4.37)cm/s,respectively.The femoral vein blood flow before and 3 days after surgery in the control group was(13.02±2.12)ml/s and(15.05±2.29)ml/s,respectively,while that in the study group was(13.36±2.09)ml/s and(16.26±2.34)ml/s,with statistical significance(P＜0.05).The study group was higher 3 days after surgery(P＜0.05).The prothrombin time before and 3 days after operation were(22.93±2.04)s and(18.13±1.34)s in the control group,and(23.24±1.99)s and(17.29±1.21)s in the study group,respectively.The thrombin time before and 3 days after operation were(24.86±2.31)s and(21.04±1.75)s in the control group,and(24.13±2.16)s and(19.89±1.53)s in the observation group,respectively.The activated partial thromboplastin time before and 3 days after surgery was(59.21±3.92)s and(49.13±3.02)s in control group,and(60.17±3.85)s and(47.09±2.98)s in observation group,respectively,and the difference was statistically significant(P＜0.05).It was lower 3 days after surgery in study group(P＜0.05).In the study group,preoperative tumor necrosis factor(TNF)-α,platelet activating factor(PAF)and thromboxen B2(TXB2)were(31.91±4.89)ng/L,(14.59±2.36)pg/ml,and(213.12±30.98)pg/ml,respectively.Three days after surgery,the levels were(36.24±4.29)ng/L,(16.12±2.59)pg/ml,and(239.86±32.85)pg/ml,respectively,with statistical significance(P＜0.05).TNF-α,PAF and TXB2 were higher in the study group 3 days after surgery(P＜0.05).There was no significant difference in the incidence of total complications between the two groups(P＞0.05).The recurrence rate of thrombosis in study group was lower than that in control group(3.77％vs 16.33％,P＜0.05).Conclusion Catheter thrombolytic balloon dilation of iliac vein for acute DVT complicated with Cockett syndrome can enhance the thrombolysis effect,improve the swelling of the affected limb,lower limb hemodynamics and coagulation function,and reduce the risk of thrombosis recurrence,which is safe and reliable.However,this treatment plan can mediate the occurrence of inflammation,and reasonable anti-inflammatory therapy should be actively implemented after surgery.

A 62-year-old man with hepatocellular carcinoma began to take tyrosine kinase inhibitor(TKI)lenvatinib orally.After taking the medicine for a week,the patient developed watery diarrhea 2 to 3 times a day.The patient received the first dose of tislelizumab.After 20 days,the patient's diarrhea worsened,nearly 40 times a day.Lenvatinib was discontinued and the second dose of tislelizumab was received,while the diarrhea was not significantly relieved.Treatments were given upon the symptoms and diarrhea was alleviated so that lenvatinib was restarted,diarrhea aggravated again and the drug was discontinued.Acute colitis complicated with colon erosion was diagnosed by colonoscopy which was presumed to be immure-associated colitis caused by programmed cell death protein 1(PD-1).The patient was admitted to hospital for liver transplantation.After the administration of immunosuppressive drugs against graft rejection,the diarrhea gradually cleared.Diarrhea caused by anti-PD-1 antibody is usually mild.In this case,mild diarrhea caused by TKI developed rapidly into severe colitis after the first dose of anti-PD-1 antibody.Mechanism of the increasing rate of adverse effect caused by the combined use of TKI and anti-PD-1 antibodies worth further discussion.

To investigate and analyze the causes of a human brucellosis epidemic in Chengjiang City in 2023 through field epidemiological investigation, and to provide a reference for future surveillance and control. A field epidemiological investigation of the case was carried out, with an active search of cases in epidemic areas. Samples from high-risk individuals, sheep, and dogs in the epidemic area were collected for brucellosis testing and pathogen isolation and culture, and the data were statistically analyzed by descriptive epidemiological method. One case of human brucellosis was detected in the outbreak, with smooth Brucella glabrata (ovine biotype 3) isolated from the patient's blood. Smooth Brucella glabrata antibodies were detected in two samples from the patient's dogs, with a positive rate of 16.67%. Tests for brucellosis in high-risk individuals and goats were negative, leading to a determination that this was an outbreak of ovine brucellosis transmitted from dogs to humans. This outbreak represented a rare instance of Brucella glabrata (ovine biotype 3) co-infected by humans and dogs. In dealing with the epidemic of human brucellosis, it is necessary to expand ideas and methods, strengthen the prevention and control of canine brucellosis, pay attention to the infection of dogs, and raise the protection awareness of dog farmers.

Objective:To evaluate the efficacy and safety of oral anisodine hydrobromide tablets in the treatment of nonarteritic anterior ischemic optic neuropathy (NAION).Methods:A multicenter nonrandomized controlled trial was conducted.A total of 282 acute NAION patients (282 eyes) were recruited from 16 hospitals in China from July 2020 to May 2021.Patients were divided into two groups according to treatment methods, which were control group (124 cases, 124 eyes) receiving regular treatment including citicoline sodium plus Ginkgo biloba leaf liquid extract or Ginkgo biloba leaf extract tablets plus mecobalamin, and experimental group (158 cases, 158 eyes) receiving treatment in control group plus oral anisodine hydrobromide tablets 1 mg, twice daily for 2 to 3 months.Best corrected visual acuity (BCVA), visual field index (VFI), peripapillary retinal nerve fiber layer (pRNFL) and radial peripapillary capillary vessel density (RPC) were assessed at 1, 2, 3, and 6 months after enrollment using the standard decimal visual acuity chart, 750i Humphery visual field analyzer, Cirrus HD-OCT 4000/Cirrus HD-OCT 5000, RTVue-XR optical coherence tomography respectively.The primary outcomes were BCVA and VFI, and the secondary outcomes were pRNFL, RPC, and the side effects during the follow-up.The study adhered to the Declaration of Helsinki.All patients were fully informed about the treatment and purpose of this study and voluntarily signed the informed consent form.The study protocol was approved by Chinese PLA General Hospital (No.S2020-021-01). Results:In all, 242 patients (242 eyes) completed the follow-up of BCVA, and 98 patients (98 eyes) completed the VFI follow-up.In terms of visual function, BCVA and VFI improved significantly over time in the two groups, and BCVA and VFI were better in experimental group than in control group at various follow-up time points (all at P<0.05). In terms of structure, pRNFL gradually decreased in both groups with the extension of treatment, and pRNFL was significanthy thinner in experimental group than in control group at various follow-up time points (all at P<0.05). There was no significant difference in RPC between the two groups at the last follow-up ( P>0.05). There were two cases with side effects and one case was discontinued due to side effects 25 days after enrollment. Conclusions:Oral anisodine hydrobromide can improve visual acuity and visual field in NAION and accelerate the regression of optic disc edema, with good safety.

Objective:To investigate the characteristics of obesity in adolescents with major depressive disorder (MDD) and its association with the depressed severity.Methods:A total of 278 adolescents with MDD were recruited according to the inclusion and exclusion criteria. Their demographic data were collected and 24-item Hamilton depression scale (HAMD-24) was used to evaluate their severity of depression. According to the body mass index (BMI) classification standard of adolescents in China, all subjects were classified into four groups(wasting group, normal BMI group, overweight group and obesity group). SPSS 26.0 statistical software was used for data analysis. The Kruskal-Wallis test and the Chi-square test were separately used for the comparison of the four groups.Spearman correlation was used to explore the relationship between BMI and HAMD-24 scores and severity.Results:Among 278 adolescents with MDD, the prevalence of body abnormality was 32.4% (90/278), among which wasting, overweight and obesity were 9.0% (25/278), 14.4% (40/278) and 9.0% (25/278) respectively. There were statistically differences in gender ( χ2=17.018, P<0.001), HAMD-24 scores ( H=9.427, P=0.024) and depressed severity( H=8.508, P=0.037) among the four groups. Multiple comparisons showed that there were only statistically differences between obesity group and normal BMI group, that was the prevalence of obesity in males was higher than that in females ( χ2=13.631, P<0.001), and the level in HAMD-24 scores ( Z=2.956, P=0.003) and depressed severity ( Z=2.832, P=0.005) was lower in obesity group than that in normal BMI group.Spearman correlation analysis showed that BMI was negatively correlated with HAMD-24 scores ( r=-0.162, P=0.007). Conclusion:There is gender difference in obesity rates among the adolescent patients with first-episode untreated MDD. And the obese patients are less depressed than those with normal BMI.

Objective:To investigate the application of critical flicker fusion frequency (CFF) in non-arteritic anterior ischemic optic neuropathy (NAION).Methods:A cross-sectional study. From January 2021 to September 2021, a total of 58 NAION patients (105 eyes) (NAION group) and 33 cases (63 eyes) in the healthy control (HC) group were included from Department of Ophthalmology of First Medical Center, PLA General Hospital. Patients underwent best-corrected visual acuity (BCVA), optical coherence tomography (OCT), visual field, CFF and flash visual evoked potential (F-VEP) examinations. BCVA examination was performed using a Snellen decimal visual acuity chart and was converted to logarithm of the minimum angle of resolution visual acuity. In the affected eyes group, there were 56 cases (72 eyes), 31 cases (43 eyes) male and 25 cases (29 eyes) female, with an average age of 49.28±11.42 years old. And the affected eyes were divided into 4 groups: <1, 1-<3, 3-<6 and >6 months according to the time interval from onset to CFF examination, which were 20(27.8%), 26 (36.1%), 17 (23.6%) and 9 (12.5%) eyes, respectively. According to the BCVA ≥0.5, 0.1-0.5, <0.1 in CFF examination, the affected eyes were divided into a mild, moderate, and severe degree, 33 (45.8%), 32(44.4%) and 7 (9.8%) eyes, respectively. Sixty-three eyes of 33 cases were in the HC group. There were 17 cases(31 eyes) males and 16 cases (32 eyes) females, with an average age of 35.18±10.96 years. Hand-held CFF detector type 2 (Japan, NEITZ company) was used for the CFF examination. The thickness of peripheral retinal nerve fiber layer (pRNFL), macular inner limiting membrane retinal pigment epithelium (mILM-RPE), F-VEP peak time and peak value and mean visual field defect (MD) values were recorded within 1 week of CFF examination. The CFF value of the above subgroups was analyzed in order using one-way ANOVA. Pearson correlation analysis was used for the correlation between CFF and F-VEP peak time, peak value, BCVA and MD. The correlations between BCVA, visual field, F-VEP, and CFF were analyzed.Results:The trichromatic values of red, green and yellow in NAION affected eyes were 22.56±10.30, 24.10±11.51, 24.81±11.41 Hz, respectively, which was significantly reduced compared with the HC group ( t=-10.53,-11.11,-11.36; P<0.05). There was no significant difference in CFF-red, green, and yellow values at different time points after the onset of the disease ( F=2.075, 1.893, 2.073; P>0.05). Compared CFF-red, green, and yellow values in NAION-affected eyes with different degrees, the difference was statistically significant ( F=31.579, 27.332, 32.055; P<0.05). The results of correlation analysis showed that the peak time of F-VEP ( r=-0.362, -0.379,-0.357; P<0.05), BCVA ( r=-0.705,-0.695,-0.714; P<0.05), and which was negatively correlated with CFF three color. MD and CFF were positively correlated ( r=0.486, 0.435, 0.450; P<0.05). Conclusion:The CFF value of the affected eye is decreased significantly in NAION-affected eyes, and CFF is more sensitive than F-VEP in reflecting visual impairment, and has a good correlation with visual function and latency of F-VEP.

Objective: To compare the changes of spontaneous brain activity in myelin oligodendrocyte glycoprotein antibody (MOG-Ab) positive and Aquaporin 4 antibody (AQP4-Ab) positive neuromyelitis optica spectrum disorder (NMOSD) by using resting-state functional magnetic resonance imaging (fMRI). Methods: A case control study was designed.A total of 11 NMOSD patients with positive MOG-Ab and 21 NMOSD patients with positive AQP4-Ab were enrolled from October 2006 to May 2017 in PLA General Hospital.Thirty-four healthy controls closely matched in age, sex and education were recruited and underwent resting-state fMRI scans.The amplitude of low-frequency fluctuation (ALFF) was extracted to investigate the spontaneous brain activity.This study was approved by Ethics Committee of PLA General Hospital (S2019-111-01). All subjects enrolled signed informed consent. Results: Two patients in the MOG-Ab positive group had seizure history, and no seizure history was observed in AQP4-Ab positive group and healthy control group.Compared with healthy control group, all patients in MOG-Ab positive group and AQP4-Ab positive group had significantly increased ALFF values of prefrontal gyrus.The ALFF values of bilateral anterior central gyrus and bilateral posterior central gyrus in AQP4-Ab positive group were 1.89±0.56 and 2.10±0.69, respectively, which were lower than 3.32±1.15 and 3.61±1.23 in MOG-Ab positive group, the differences were statistically significant (both at P<0.001, AlphaSim correction). Conclusions Resting-state fMRI could provide new evidence of possibly multi-focal disease mechanisms.Hyperactivity in prefrontal cortex, motor cortex and somatosensory cortex might reflect differences in pathological processes between MOG-Ab positive and AQP4-Ab positive NMOSD patients.

Objective To explore the clinical features,primary lesions and prognosis of optic nerve metastases.Methods Seven patients (11 eyes) with optic nerve metastatic tumor diagnosed by the examinations of ophthalmology,laboratory and pathology in Chinese PLA General Hospital from April 2015 to September 2017 were included in this study.All patients underwent BCVA,flash VEP,OCT,orbital MRI,serum tumor marker,cerebral spinal fluid detection and PET-CT.Histopathological examination of primary or near superficial metastases was performed.The follow-up period was ranged from 16 to 44 months,with the mean of 23.0 ± 10.9 months.The clinical characteristics,primary tumor,imaging features,treatment and clinical prognosis in the patients were analyzed.Results Among 7 patients,there were 5 males and 2 females,with the mean age of 53.90± 14.99 years;3 patients with unilateral optic nerve involvement,4 patients with bilateral optic nerve involvement;5 patients (71.4％) first diagnosed in ophthalmology.Five patients (45.5％) were misdiagnosed as optic neuritis,optic disc edema in 6 eyes (54.5％).All of them appear loss of visual acuity,including 8 eyes (72.7％) with BCVA＜ 0.1,2 eyes (18.2％) with BCVA 0.1-0.5,1 eye (9.1％) with BCVA ＞ 0.5.MRI results show that 1 patient with intraorbital segment,1 patient with internal segment of optic canal,4patients with intracranial segment,1 patient with intracranial segment and optic chiasma involved simultaneously,4 patients involving surrounding tissue.There were 4 patients (57.1％) with lung cancer,2 patients (28.6％) with kidney cancer,1 patient (14.3％) with gastric cance;6 patients (85.7％) with metastasis from other sites,2 patients with brain metastasis (1 patient with meningitis carcinomatosa).There were 2 patients (28.6％) with previous primary cancer surgery.After diagnosis,1 patient received chemotherapy,1 patient received radiotherapy,5 patients gave up treatment.At the end of follow-up,1 patient (1 eye) of chemotherapy with BCVA increased by 2 line;1 patient (2 eyes) of radiotherapy with no change in BCVA;of the 5 patients who gave up treatment,1 patient died of disease,1 patient lost follow-up,and 3 patients (4 eyes) had no change in BCVA.Conclusions With atypically clinical manifestations,the optic nerve metastases easily misdiagnosed as optic neuritis,and with poor therapeutic effect.Primary lesions are mostly found in lung cancer.

Objective To evaluate the efficacy and safety of repeated treatments with low-dose rituximab for relapsing neuromyelitis optica spectrum disorder (NMOSD).Methods A perspective study.21 patients who were diagnosed with NMOSD one year ago were recruited for rituximab treatment.Of 21 patients,one was male,20 were females.Onset age was 10-51 years,the mean onset age was (26.2± 12.0) years.Duration of disease was 2.3-25.8 years,the mean duration was (9.2 ± 5.9) years.Best corrected vision activity (BCVA),expanded disability status scale (EDSS),annualized relapsing rate (ARR) were valued to investigate the efficacy and safety of repeated treatments with low-dose rituximab.The BCVA was examined using Snellen chart,and converted to logMAR.The mean BCVA was 1.13 ± 1.09,the mean BCVA in better eyes was 0.4±0.68,the mean BCVA in latter eyes was 1.87±0.90.The mean EDSS was 3.09±0.70.The mean ARR was 1.04± 0.65.All patients underwent two cycles of RTX treatment.The annually induction treatment was RTX 100 mg per week for 4 weeks.Of 21 patients,12 patients had treatment within one month after attack.The mean follow-up period was (28.4±4.9) months.The side effects were recorded,BCVA,EDSS,ARR were valued to investigate the efficacy and safety of repeated treatments with low-dose rituximab.Paired t test,independent sample t test and Chi-squared test were used.Results The mean BCVA at last follow-up was 0.62 ± 0.91,the mean BCVA in better eye was 0.62±0.91,the BCVA in latter eye was 1.0± 1.01.The mean EDSS was 2.26± 1.07.The mean ARR was 0.21 ± 0.3.After the treatment,patient had significant improvement on BCVA in worst eye (t=4.256),ARR (t=2.900),EDSS (t=4.620) with the significant differences (P＜0.05).Thirteen relapses in 9 patients were observed.B lymph cells were more than 0.01％ in all relapses.There was no significant difference on the BCVA in better eye (t=1.840,P＞0.05).There were 9 patients had relapse,13 times in total.Of 13 relapses,B lymph cell count was performed in 12 relapses,and the counts were 0.01％-0.14％.There were no significant difference between relapsed patients and non-relapsed patients on onset age (t=0.67,P=0.51),whether underwent plasma exchange treatment (x2=1.61,P＞ 0.05),with/without auto-immune antibody ratio (x2=1.61,P＞ 0.05).Of 21 patients,8 patients had side effects,including 5 patients with infection,4 patients with chest congestion,3 patients with hair losing,2 patients with skin rashes,headache and short of breath,1 patient with tinnitus,palpitation and fatigue.Four patients had more than one symptom.Of all patients who had side effects,slowing down the infusion speed of RTX or infusing 5 mg of dexamethasone could relieve the discomfort.Conclusion Lose-dose rituximab reduces the frequency of NMOSD relapses and is well tolerated.
