Objective To establish a prediction model for the occurrence of non-occupational carbon monoxide poisoning events in Beijing, and to provide scientific basis and theoretical support for the prevention and warning of poisoning events. Methods Based on the monitoring data of non-occupational carbon monoxide poisoning events in Beijing from 2016 to 2024, the seasonal ARIMA model and seasonal index model were established to analyze the data and predict the occurrence of events. Results Between 2016 and 2024, a total of 436 cases of non-occupational carbon monoxide poisoning were reported in Beijing, showing a downward trend. The established SARIMA model and seasonal index model were SARIMA (1,0,0) (1,1,0) 12, Yt = (-0.0339t+5.8863) × St, and the average relative errors were 65.42% and 29.19%, respectively. In terms of months, the SARIMA model had better predictive performance during April and summer (June to August), while the seasonal index model was superior in other months. By combining the two models, the predicted number of events in 2025 was as follows: 3, 2, 2, 3, 1, 5, 2, 7, 1, 1, 1, and 2. Conclusion The seasonal index model has the best prediction effect on the non-occupational carbon monoxide poisoning events in Beijing throughout the year, and the number of summer events predicted by SARIMA model is closer to the actual values. The two models can be combined to predict the trend of non-occupational carbon monoxide poisoning, which provides a scientific basis for the prevention and control of carbon monoxide poisoning in the future.

Pancreatic polypeptide(PP),a pancreatic hormone containing 36 amino acids,plays impor-tant roles in the diagnosis and evaluation of pancreatic function,injury and diseases.In this study,a phage nanobody library against PP was constructed to screen specific PP nanobodies,which would be used to evaluate whether they have binding activity with PP antigen.After PP antigen with high purity was prepared by prokaryotic expression system,it was used to immunize alpaca to construct the nanobody li-brary against PP with high storage capacity and high abundance,from which 8 strains of PP nanobodies were obtained by phage display.One of nanobody strain(PP-VHH)was selected to be expressed in a prokaryotic expression system,which was induced overnight by IPTG.After purification and identifica-tion,the antigen-antibody binding activity and PP level in serum were detected by indirect ELISA and Sandwich ELISA methods,respectively.The results showed that PP-VHH had binding activity with PP,which could be used to detect PP in chicken and human serum.The Sandwich ELISA methods with R2 of the fitting curve 0.9868 could be used to detect PP concentrations of 48-55 pg/mL in the serum of chick-ens,while the concentrations of PP in human serum varied significantly.In summary,PP-VHH screened from nanobody library against PP could detect PP in serum,which would supply the basis for evaluation of abnormal pancreatic function and diagnosis of relative disease.

Animal drugs have been used in the treatment of uro-andrological diseases since ancient times.At present,the clini-cal use of animal drugs is mostly based on the experience of doctors.From the perspective of the diversified theories of traditional Chi-nese medicine(TCM),this paper summarizes the experience of predecessors in the use of animal drugs,and believes that under the guidance of the TCM theories,the application of animal drugs in the treatment of uro-andrological diseases has achieved multi-dimen-sional and diversified development,as in the treatment of chronic prostatitis based on the theories of"heat poison","stasis poison"and"aromatherapy through the orifice",and in the management of ED from the perspective of"kidney deficiency","qi-blood dishar-mony"and"collateral disease",which accords with the mainstream thought of current scholars in the differentiation and treatment of uro-andrological diseases.At the same time,it pointed out the problems to be attended to in the clinical use of animal drugs,aiming to provide some reference ideas for the clinical treatment of uro-andrological diseases with animal drugs.

Studies have suggested that the nucleus accumbens (NAc) is implicated in the pathophysiology of major depression; however, the regulatory strategy that targets the NAc to achieve an exclusive and outstanding anti-depression benefit has not been elucidated. Here, we identified a specific reduction of cyclic adenosine monophosphate (cAMP) in the subset of dopamine D1 receptor medium spiny neurons (D1-MSNs) in the NAc that promoted stress susceptibility, while the stimulation of cAMP production in NAc D1-MSNs efficiently rescued depression-like behaviors. Ketamine treatment enhanced cAMP both in D1-MSNs and dopamine D2 receptor medium spiny neurons (D2-MSNs) of depressed mice, however, the rapid antidepressant effect of ketamine solely depended on elevating cAMP in NAc D1-MSNs. We discovered that a higher dose of crocin markedly increased cAMP in the NAc and consistently relieved depression 24 h after oral administration, but not a lower dose. The fast onset property of crocin was verified through multicenter studies. Moreover, crocin specifically targeted at D1-MSN cAMP signaling in the NAc to relieve depression and had no effect on D2-MSN. These findings characterize a new strategy to achieve an exclusive and outstanding anti-depression benefit by elevating cAMP in D1-MSNs in the NAc, and provide a potential rapid antidepressant drug candidate, crocin.

Primary hyperparathyroidism is a disease with a large potential population. Some cases of primary hyperparathyroidism are non-primary, preventable and curable at early stage, requiring long-term follow-up after surgery. Therefore, all-round and full-cycle management are necessary for primary hyperparathyroidism, which involves an enhancing focus on etiological prevention, early detection, prompt diagnosis, timely intervention, multi-disciplinary standardized diagnosis and treatment, and postoperative scientific management. Meanwhile, implementing a "12+5+1" multidisciplinary joint diagnosis and treatment model, along with a two-way referral model, to achieve the transition from a disease-oriented diagnostic and treatment model to a patient-oriented, all-round and full-cycle interdisciplinary management model. This management can reduce the incidence and recurrence rate of primary hyperparathyroidism, and related osteoporosis or osteopenia, fractures, nephrolithiasis, metastatic vascular calcification, and systemic abnormal migratory calcium deposits, improve the overall quality of life and prognosis of patients.

Objective To overcome the limitations of existing human respiratory syncytial virus(hRSV)animal models,such as semi-permissiveness and short duration of infection,this study established an IL2rg gene knockout(IL2rg-/-)rat model using TALEN gene editing technology.Methods The animal model was infected with hRSV intranasally.Clinical characteristics,body weight,and temperature changes were observed over the infection period(0～35 days).The total viral loads in respiratory organs,such as the nasal tissue,trachea,and lungs,were measured at various time points(4,11,20,and 35 days post-infection).Pathological analysis was conducted on target organs at the endpoint of observation(35 days post-infection).Changes in peripheral blood T,B,NK,and NKT cells and various cytokines were assessed at various time points(4,20,and 35 days post-infection).Results(1)IL2rg/-knockout rats sustained high viral loads in the nasal cavity upon intranasal inoculation with hRSV.The average peak titer rapidly reached 1 × 1010 copies/g in nasal tissue and 1 × 107 copies/g up to 5 weeks post-infection.(2)However,no significant pathological changes were noted in nasal,tracheal,or lung tissues.(3)An increase was observed in the content of peripheral blood B cells in hRSV-infected IL2rg--rats.(4)IL-6 and MCP-1 were increased in the early stage of infection and then decreased at the end of the observation period.Conclusions This study established a new IL2rg-/-rat model using TALEN technology and found that this model effectively supported high-level replication and long-term infection of hRSV,providing a good basis for antiviral drug screening and in vivo efficacy evaluation of anti-hRSV antibodies.

Abnormal tumour cell adhesion is a key step in tumour metastasis， in which weakened homologous and enhanced heterologous adhesion of tumour cells is an important cause of tumour metastasis. Chronic stress can activate the sympathetic nervous system to link and regulate the homologous and heterologous adhesion of tumour cells and exacerbate tumour metastasis. Combining the understanding of traditional Chinese medicine （TCM） and Western medicine on tumour metastasis， it is believed that the mechanism of "qi constraint and stagnation， tumor toxin transmission and retention" in TCM theory is highly related to the abnormal adhesion of tumour cells triggered by chronic stress. Qi constraint and stagnation is closely related to chronic stress and its activation of the sympathetic nervous system， and transmission and retention of tumor toxin explained the mechanism of tumour metastasis due to abnormal adhesion of tumour cells from the perspective of TCM. By regulating the key link of sympathetic nervous system-tumour cell adhesion， application of the formulas of regulating qi and resolving toxin can improve chronic stress and inhibit tumour metastasis.

【Objective】 To compare the risk of generalization in patients with ocular myasthenia gravis (OMG) receiving or not receiving immunosuppressive treatment. 【Methods】 The data of patients with OMG registered in Tangdu Hospital of Air Force Military Medical University from January 1, 2015 to May 1, 2019 were reviewed; the patients were divided into treatment group and control group according to whether they had received immunosuppressive treatment. The multivariate Cox proportional hazards regression model analysis was used to compare the risk of generalization between the two groups of patients within 2 years of onset. Sensitivity analysis was used to evaluate the duration of immunosuppressive treatment and the risk of generalization under different immunotherapy regimens. By using stratified analysis, the consistency of the main results across different levels of subgroup factors was evaluated. 【Results】 A total of 702 OMG patients were collected. Of them 367 patients (52.3%) were included in the treatment group, with an average onset age of (50.54±15.1) years, and 159 (43.3%) being female. Another 335 patients (47.7%) were included in the control group, with an average age of (49.1±14.6) years, and 159 ones (47.5%) were female. A total of 28 cases (7.7%) in the treatment group and 106 cases (31.6%) in the control group developed generalization during the observation period. After multivariate-adjusted Cox model analysis, patients who had received immunosuppressive treatment had a significantly lower risk of generalization compared with the control group (HR=0.24; 95% CI: 0.15-0.37; P<0.001). Sensitivity analysis found that the longer the duration of immunosuppression, the lower the risk of generalization (HR=0.88; 95% CI: 0.85-0.91; P<0.001). Stratified analysis showed that immunosuppressive therapy reduced the risk of generalization in different subgroups of patients. 【Conclusion】 Early immunosuppressive treatment can significantly reduce the risk of generalization in patients with OMG.
