Objective:To investigate the efficacy and treatment adherence of digital cognitive behavioral therapy for insomnia (dCBT-I) in patients with insomnia disorder accompanied by anxiety and depressive symptoms, and to provide empirical evidence for its clinical application.Methods:From December 2023 to December 2024, 102 patients with insomnia disorder accompanied by anxiety and depressive symptoms were recruited from the outpatient department of Inner Mongolia Brain Hospital and randomly assigned to either the dCBT-I group ( n=56) or the digital sleep hygiene education (dSHE) group ( n=46). The dCBT-I group received a 4-week intervention comprising 5 core modules, while the dSHE group received 4 weeks of digital sleep hygiene education. Both groups received weekly guidance from clinical psychologists. Subjective sleep quality (Insomnia Severity Index, ISI), anxiety (Hamilton Anxiety Scale, HAMA), and depressive symptoms (17-item Hamilton Depression Scale, HAMD 17) were assessed at baseline, week 4, week 8, and week 12. Objective sleep parameters (polysomnography, PSG) and cognitive function (Repeatable Battery for the Assessment of Neuropsychological Status, RBANS) were evaluated at baseline and week 4. Linear mixed-effects model was used to analyze the effects of group, timepoint, and their interaction on outcome measures, after controlling medication history, age, sex, education level, ethnicity, and marital status as covariates. Results:A total of 76 patients (dCBT-I: n=42; dSHE: n=34) completed the 4-week intervention, yielding a treatment adherence rate of 74.5%(76/102). At weeks 4, 8, and 12, the dCBT-I group demonstrated significantly lower scores on the ISI, HAMA, and HAMD 17 scales compared to the dSHE group (β=-1.70--0.66, t=-15.38--6.21, all P<0.05), along with higher rates of medication reduction (χ 2=16.40, 9.22, 6.66, all P<0.05). No significant differences were observed in PSG parameters between the two groups. However, the dCBT-I group demonstrated significant improvements in RBANS subdomains, including immediate memory, language function, and delayed memory (β=0.45, 0.86, 1.43, t=3.09, 2.67, 4.36, all P<0.05). Conclusion:dCBT-I is an effective and well-adhered intervention for patients with insomnia disorder accompanied by anxiety and depressive symptoms, warranting broader clinical implementation.

BackgroundThe functional changes of the default mode network （DMN） are closely related to the onset of major depressive disorders. However， the relationship between the DMN subsystem （core subsystem， dorsomedial prefrontal cortex subsystem， medial temporal lobe subsystem） and symptoms of first-episode major depressive disorder remains unclear. ObjectiveTo investigate abnormal functional connectivity between DMN subsystems and the whole brain in first-episode major depressive disorder patients during the resting-state， and to analyse the correlations between these functional connectivity patterns and clinical symptoms， so as to reveal the potential neural mechanisms from the perspective of DMN subsystem. MethodsFrom September 2020 to September 2023， a total of 64 first-episode outpatients and inpatients meeting the diagnostic criteria for major depressive disorder in the Diagnostic and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） were enrolled at the Inner Mongolia Autonomous Region Mental Health Center as the study group. During the same period， 54 healthy volunteers matched for age， gender， and years of education were recruited from the community as the control group. Both groups were assessed using the Hamilton Depression Scale-24 item （HAMD-24）. Resting-state functional magnetic resonance images （rs-fMRI） of the two groups were acquired using a Siemens 3.0 T scanner， and differences in functional connectivity between DMN subsystems （core subsystem， dorsomedial prefrontal cortex subsystem， medial temporal lobe subsystem） and the whole brain were compared. The functional connectivity values of brain regions with statistically significant differences between the two groups were extracted. Spearman's rank correlation coefficient analysis was used to investigate the correlation between these functional connectivity values and HAMD-24 scores of the study group. ResultsUltimately， 46 patients and 43 controls completed the study. Compared with the control group， the study group exhibited significantly stronger functional connectivity in the following pathways： between the right superior parietal lobule （core subsystem） and right cerebellar lobule VIII （t=3.954， P<0.05， GRF-corrected）， between the right lateral temporal cortex （dorsomedial prefrontal cortex subsystem） and right cerebellar lobule VIII， right and left hippocampi， right medial， and paracingulate gyrus （t=4.595， 4.208， 5.200， 4.038， P<0.05， GRF-corrected）， and between the temporoparietal junction （dorsomedial prefrontal cortex subsystem） and left lingual gyrus and right cerebellar lobule VIII （t=3.557， 4.274， P<0.05， GRF-corrected）. Conversely， weaker functional connectivity was observed between the right inferior frontal gyrus and left gyrus rectus （t=-3.824， P<0.05， GRF-corrected）. Furthermore， within the study group， the functional connectivity values between the right lateral temporal cortex and right hippocampus， as well as between the temporoparietal junction and right cerebellar lobule VIII， were both negatively correlated with the HAMD-24 cognitive impairment factor score （r=-0.306， -0.318， P<0.05）. ConclusionIncreased functional connectivity between the DMN （specifically its core and dorsomedial prefrontal cortex subsystems） and cerebellum， partial limbic system， and lingual gyrus may be associated with the neuropathology of first-episode major depressive disorder. Furthermore， alterations in functional connectivity between the dorsomedial prefrontal cortex subsystem and both the cerebellum and hippocampus in these patients may be related to cognitive function. ［Funded by 2019 Annual Inner Mongolia Autonomous Region Natural Science Foundation Project （number， 2019MS03038）； 2023 Annual Inner Mongolia Autonomous Region Natural Science Foundation Project （number， 2023MS08028）］

To rapidly and accurately detect Mycobacterium avium subsp.paratuberculosis(MAP),this study designed and screened primers and probes using its specific gene F57 as the detection target,established a recombinant enzyme-mediated isothermal amplification(RAA)fluorescence detection method,and applied this method to detect 116 clinical samples from cattle and sheep.The results showed that using the primer and probe combination B12F/B2R(0.4 μmol/L)+Probe B(0.12 μmol/L),MAP could be detected at a constant temperature of 42 ℃ within 20 min;this de-tection method had no cross-reaction with 11 common pathogens such as Escherichia coli,Clos-tridium,and bovine viral diarrhea in sheep and cattle;the lowest detection limit was 1.0×102 cop-ies/μL;the coefficient of variation was 3.77％—5.29％;24 clinical samples were positive,with a co-incidence rate of 88.89％with GBT27637-2011.In summary,this study established a fluorescent RAA detection method for MAP,which is simple,rapid,highly specific,sensitive,reproducible,and has a high coincidence rate with national standards,making it suitable for clinical detection and epi-demiological studies.

Objective:To investigate the predictive value of preoperative peripheral blood lymphocyte to monocyte ratio (LMR) for lymph node metastasis in gastric cancer.Methods:Data of 177 gastric cancer patients who underwent surgical treatment in Beijing Shijitan Hospital from Jan 2014 to May 2017 were retrospectively analyzed. According to the ROC curve, the optimal critical value is determined to be 3.79. By this value, patients were divided into high LMR group (LMR≥3.79) and low LMR group (LMR<3.79). Patients′ clinicopathological characteristics were collected to analyze the relationship between LMR and lymph node metastasis and lymph node N staging.Results:A comparison of LMR and N1 and N2 stage between the two groups showed no significant difference, but both N1 and N2 had statistical defference with N3 ( P<0.05), suggesting a positive correlation between low LMR and high N stage. Logistic regression analysis proves that low LMR is significantly correlated with metastatic lymph node when the number was more than 6. Conclusion:Low LMR is positively correlated with lymph node metastasis in gastric cancer patients.
