Objective:To evaluate the effects of sequential immunotherapy with radiotherapy on survival time and immune function in patients with unresectable stage III non-small cell lung cancer (NSCLC) in a real-world study.Methods:Data of 84 patients with unresectable stage III NSCLC who were treated at the Affiliated Hospital of Inner Mongolia Medical University from January 2021 to December 2022 (retrospective cohort) and from January 2023 to December 2023 (prospective cohort) were collected. The patients were divided into the combination group ( n=40) and radiotherapy group ( n=44) based on whether they received sequential immunotherapy or not. The progression-free survival (PFS) and overall survival (OS) between two groups were compared using standardized mortality ratio weighting (SMRW). Univariate Cox proportional hazards model, multivariate regression analysis, multi-model comparison of propensity score matching and subgroup analysis were emploed to analyze the robustness of clinical efficacy between two groups. E-value analysis was used to analyze the sensitivity of unmeasured confounding factors in observational studies. Additionally, the percentage of CD4 +T cells, CD8 +T cells and natural killer (NK) cells, and CD4 +/CD8 + T cell ratio before and after treatment between two groups were compared using analysis of covariance. Results:Among 84 patients, 77 (92%) cases were male and 7 (8%) were female. Among them, 42 (50%) were aged 65 years or older. The variables showed high homogeneity after SMRW, with a standardized mean difference of less than 0.1. In the combination group, the median PFS [17.0 months vs. 7.0 months, HR=0.260, 95% CI: 0.130-0.490, P<0.001] and OS [not reached vs. 24.0 months, HR=0.210, 95% CI: 0.070-0.590, P=0.002] were significantly longer compared to that in the radiotherapy group, with statistically significant differences. The study results were confirmed by robustness and sensitivity analyses. After treatment, patients in the combination group showed a statistically significant increase in the percentage of CD4 + T cells and NK cells, and CD4 +/CD8 + T cell ratio, as well as a decrease in the percentage of CD8 + T cells compared to those in the radiotherapy group (all P<0.05). Conclusions:Sequential immunotherapy following radiotherapy can significantly improve survival and prognosis of unresectable stage III NSCLC patients. The survival benefit is even greater when combined with chemotherapy. The main mechanism of the survival benefit may be the improvement of anti-tumor immune function.

Objective To investigate the effects of light-at-night exposure on anxiety and depression behaviors in mice and to explore the underlying neural mechanisms.Methods Six-week-old male C57BL/6J mice were randomly assigned to a control(Ctrl)group and a light-at-night exposure(LAN)group.Mice in the LAN group were exposed to 460 nm blue light for 1 h daily during the zeitgeber time(ZT)13-14 while the Ctrl group mice were maintained under a 12-h light/12-h dark cycle.Behavioral tests were conducted at different time points following LAN exposure to evaluate anxiety and depression behaviors in the mice.Immunofluorescence staining was used to observe the effect of LAN on c-fos expressions in the medial prefrontal cortex(mPFC),basal ateral amygdala(BLA),paraventricular nucleus(PVN)and paraventricular thalamus(PVT).ELISA was performed to measure changes in serum corticosterone,adrenocorticotropic hormone(ACTH)and corticotropin-releasing hormone(CRH)levels.Golgi staining was applied to measurethe dendritic spine density and morphology from mPFC and CA1.Western blotting analysis was conducted to detect expression levels of brain-derived neurotrophic factors(BDNFs),phosphorylated tropomyosin receptor kinase B(p-TrkB)/TrkB,postsynaptic density protein 95(PSD95)and synaptophysin(SYP)in the mPFC.Results Mice exhibited anxiety-like behaviors after 14 days of LAN exposure,with depression-like behaviors emerging after 28 days.LAN exposure of 28 days led to a significant increase in the number of c-fos-positive neurons in the mPFC,BLA,PVN and PVT(P＜0.05),resulted in elevated serum corticosterone levels(P＜0.01)and reduced protein expression levels of BDNF and SYP(P＜0.05).Furthermore,there was a marked decrease in synapse numbers and synaptic density in the mPFC(P＜0.01).Conclusion Prolonged exposure to blue light at night enhances neuronal activity in the mPFC and BLA and suppresses the BDNF/TrkB signaling pathway by activating the hypothalamic-pituitary-adrenal axis(HPA),thus leading to synaptic structural and functional damage and inducing anxiety and depression behaviors in mice.

Cervical cancer is one of the most common gynecological malignant tumors in China. Given their lack of obviously early symptoms, more than half of patients with cervical cancer are diagnosed in the middle and late stages of this malignancy, resulting in poor prognosis. Finding new therapeutic targets is the current research direction. Metabolomics, as a new omics technology, is expected to provide new targets for tumor precision diagnosis and treatment through the analysis of the changes and potential mechanisms of metabolites in tumor occurrence and development by chromatography, mass spectrometry, and other technologies. Herein, we review the research methods of metabolomics; metabolic characteristics of cervical cancer; and progress of the research on metabolomics in cervical cancer diagnosis, curative effect prediction, and prognosis evaluation to provide new ideas for the precise diagnosis and treatment of cervical cancer.

Objective: To analyze the correlation between refractive errors and physical development indicators among primary school students aged 6 to 9, so as to provide a scientific basis for the development of effective prevention and control measures. Methods: A stratified cluster random sampling method was used to recruit 2 833 elementary school students aged 6 to 9 from Guangdong Province for vision screening, ocular biometry, and physical examinations in Octorber, 2020. The Chi square test, t-test, and ANOVA were employed to compare myopia rates and indicator values across different groups. Multiple linear regression models were used to analyze the correlations between height, weight, and body mass index (BMI) with refractive development indicators. Results: The screening myopia rate among primary school students aged 6 to 9 was 16.7%, and the myopia rate increased with age ( χ 2= 51.58 , P <0.01). The height and weight of the myopic group [(126.96±7.41)cm, (26.59±6.45)kg] were higher than those of the non myopic group [(124.76±7.77)cm, (25.42±5.87)kg] ( t =5.84, 3.65, P <0.01). The mean values of spherical equivalent (SE), axial length (AL), anterior chamber depth (ACD), and AL/corneal curvature radius (CR) ratio for students aged 6 to 9 were (-0.17±1.04)D, (22.96±0.78)mm, (3.38±0.24)mm, and (2.95±0.08), respectively, with statistically significant differences across different age and myopia severity groups ( t =37.08, 119.20, 41.54, 133.60; 935.30, 184.10, 73.95, 498.50, P < 0.01). After adjusting for gender, age, and residence, the multiple linear regression model showed that height was positively correlated with AL and CR, weight was positively correlated with ACD, and BMI was positively correlated with AL and ACD ( β = 0.191 , 0.070, 0.035, 0.013, 0.007, P <0.05). When stratified by myopia status, results for the non-myopic group were similar to the overall results, whereas in the myopic group, the correlations between height, BMI, and AL were not statistically significant ( P > 0.05). Conclusions Among primary school students aged 6 to 9, height and BMI are positively correlated with AL in the non myopic group but no similar correlation is observed in the myopic group, indicating that factors other than physical development, such as environmental and behavioral factors, should be considered for their impact on refractive development.

Objective To investigate the impact of whole body vibration training combined with intermittent blood flow restriction on the motor function and community activity in elderly stroke patients with hemiplegia.Methods A total of 80 convalescent hemiplegic patients after stroke who were hospitalized in the Rehabilitation Medicine Department of Yichang Central People's Hospital(Xiling Campus)from October 2021 to December 2023 were included and randomly divided into control group(n=25),vibration group(n=28)and combination group(n=27)using the random number table method.All patients received conventional rehabilitation training,on the basis;the vabration group received whole body vibration training,while the combination group received whole body vibration training combined with intermittent blood flow restriction.Before and after 6 weeks of training,the balance function was evaluated with Berg balance scale(BBS),while the gait function was tested with 6-minute walking test(6MWT)and the Community Balance and Mobility scale(CB&M)was used to assess the community activity ability.The community balance and mobility(CB&M)were evaluated in the first and third month after discharge.Results There was no significant difference in BBS,CB&M scores and 6MWT walking distance between the three groups before training(P>0.05).After 6 weeks of training,the three groups showed significant increases in the BBS,CB&Mscores and the walk distance of 6MWT(P<0.001).Furthermore,compared with the control group,the combination group and the vibration group were significantly beter(P<0.05),and there was no signifi-cant difference between the combination group and the vibration group(P>0.05).At the first and third month of follw-up after discharge,the CB&M scores of the three groups were significantly higher than those of the control group(P<0.05),while there was no significant difference between the CB&M scores of the combination group and the vibration group at the first month of follow-up(P>0.05).But the CB&M scores of the combination group was higher than those of the vibration group at the third month of follow-up,and the difference was statistically signifi-cant(P<0.05).Conclusion On the basis of conventional rehabilitation,whole body vibration training combined with intermittent blood flow restriction can significantly enhance balance function,balance confidence,walking ability and mobility in early stage of community life for elderly stroke patients with hemiplegia,potentially facilitat-ing their return to community life.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To explore the occurrence of immune-related adverse events (irAEs) and the relationship to efficacy of camrelizumab in treatment for patients with non-small cell lung cancer (NSCLC).Methods:Clinical data of patients with NSCLC who received camrelizumab in at the Affiliated Hospital of Inner Mongolia Medical University from December 2020 to December 2022 were collected, and the efficacy of camrelizumab and the occurrence of irAEs were retrospectively analyzed. Patients were divided into irAEs group and non-irAEs group according to whether they developed irAEs. The objective response rate (ORR), disease control rate (DCR), and progression-free survival (PFS) of the 2 groups were compared.Results:A total of 48 patients were entered in the analysis, including 41 males (85.4%) and 7 females (14.6%), with an age of (65.9±7.4) years; the median treatment cycle was 9 (6, 14); the overall ORR was 52.1% (25/48), the DCR was 83.3% (40/48), and the median PFS was 11 months. Among the 48 patients, 34 patients (70.8%) had 59 times of irAEs, of which 8 patients (16.7%) had at least one irAE of grade ≥3. The median time of irAEs occurrence was 5 (3, 7) treatment cycles. The irAEs with an incidence of >10% included reactive cutaneous capillary endothelial proliferation (RCCEP), thyroid injury, skin injury, lung injury, liver injury, and blood toxicity, with the incidences of 37.5% (18/48), 18.8 (9/48), 16.7% (8/48), 12.5% (6/48), 10.4% (5/48), and 10.4% (5/48), respectively. Compared with non-irAEs group, patients in the irAEs group had higher ORR and DCR [64.7% (22/34) vs. 3/14, 91.2% (31/34) vs. 9/14] and longer median PFS (12.0 months vs. 7.0 months, hazard ratio=0.418, 95% confidence interval: 0.193-0.905), and the differences were statistically significant (all P<0.05). Conclusions:The common irAEs of camrelizumab in treatment for patients with NSCLC was RCCEP, and fewer serious irAEs occurs. To a certain extent, patients who experience irAEs during camrelizumab treatment may predict a more pronounced therapeutic response.
