Objective:To investigate the safety of the tetravalent meningococcal conjugate vaccine (MPCV-ACYW) in combination with the inactivated poliomyelitis (IPV) vaccine and diphtheria-tetanus-acellular pertussis (DTaP) vaccine for infants aged 3-5 months and provide real-world evidence for the immunization strategy of vaccine combination.Methods:From June to October 2023, a total of 600 3-month-old infants were selected and divided into three groups: control group, mono-vaccination group and combined vaccination group. They were simultaneously or individually vaccinated with MPCV-ACYW, IPV and DTaP vaccines at 3, 4, and 5 months of age, respectively. The incidence rate of adverse reactions within 30 days after each dose was observed.Results:All 600 infants completed at least one vaccination and entered the safety data analysis. The age of the control group (100 infants), the mono-vaccination group (250 infants), and the combination group (250 infants) was (101.20±7.88), (102.26±7.94), and (102.35±7.76) days, respectively. The body lengths were (63.00±3.02), (62.55±3.06), and (63.14±4.02) cm, respectively. The body weights were (6.90±0.77), (6.86±0.94), and (6.99±0.95) kg, respectively. Boys accounted for 49%, 50.4%, and 52.4%, respectively, with no statistically significant differences (all P>0.05). The overall incidence rates of adverse reactions in the control group, mono-vaccination group, and combined vaccination group were 4.00%, 2.80%, and 3.20%, respectively, with systemic adverse reaction rates of 3.00%, 2.40%, and 2.00%. The incidence rates of local adverse reactions were 1.00%, 0.40%, and 1.20%, with no statistically significant differences (all P>0.05). Adverse reactions were mainly grade 1, with incidence rates of grade 1 adverse reactions of 3.00%, 2.00%, and 1.60% in the three groups, and incidence rates of grade 2 adverse reactions of 1.00%, 0.80%, and 1.60%, respectively. No grade 3 or 4 serious adverse reactions occurred, and the differences were not statistically significant (all P>0.05). The adverse reaction symptoms of the three groups were mainly systemic reactions, among which fever and diarrhea symptoms were reported in individual cases in each group, with no statistically significant differences in the incidence rate (all P>0.05). The symptoms of adverse reactions were mostly transient and self-relieved, all of which were cured. Conclusion:The combination of MPCV-ACYW and IPV or DTaP vaccines is safe for infants aged 3-5 months.

Purpose: Myofibroblastic cancer-associated fibroblasts (myCAFs) are important components of the tumor microenvironment closely associated with tumor stromal remodeling and immunosuppression. This study aimed to explore myCAFs marker gene biomarkers for clinical diagnosis and therapy for patients with bladder cancer (BC). Materials and Methods: BC single-cell RNA sequencing (scRNA-seq) data were obtained from the National Center for Biotechnology Information Sequence Read Archive. Transcriptome and clinical data were downloaded from The Cancer Genome Atlas and the Gene Expression Omnibus databases. Subsequently, univariate Cox and LASSO (Least Absolute Shrinkage and Selection Operator regression) regression analyses were performed to construct a prognostic signature. Immune cell activity was estimated using single-sample gene set enrichment analysis whilst the TIDE (tumor immune dysfunction and exclusion) method was employed to assess patient response to immunotherapy. The chemotherapy response of patients with BC was evaluated using genomics of drug sensitivity in cancer. Furthermore, Immunohistochemistry was used to verify the correlation between MAP1B expression and immunotherapy efficacy. The scRNA-seq data were analyzed to identify myCAFs marker genes. Results: Combined with bulk RNA-sequencing data, we constructed a two-gene (COL6A1 and MAP1B) risk signature. In patients with BC, the signature demonstrated outstanding prognostic value, immune infiltration, and immunotherapy response. This signature served as a crucial guide for the selection of anti-tumor chemotherapy medications. Additionally, immunohistochemistry confirmed that MAP1B expression was significantly correlated with immunotherapy efficacy. Conclusions Our findings revealed a typical prognostic signature based on myCAF marker genes, which offers patients with BC a novel treatment target alongside theoretical justification.

High flow nasal cannula（HFNC）is a novel oxygen therapy developed in recent years，and has been successfully used in pediatric diseases such as bronchiolitis and pneumonia.Although there has been a lack of clinical application guidelines in pediatrics，it has been increasingly applied to the treatment of exacerbations of bronchial asthma.This review focused on efficacy，application timing，complications and parameters adjustment of HFNC in children with asthma exacerbation，so as to further guide the clinical use.

Objective:To investigate the clinical effect of the "Tongluo" technique on gastrocnemius muscle hardness and muscle tone in children with spastic cerebral palsy (SCP) using shear wave elastography (SWE).Methods:Forty children with SCP who were treated at the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine from January 2020 to June 2021 were selected as the observation group and received the "Tongluo" technique intervention. At the same time, 20 normal children were selected as the control group, without any intervention. Compare the various indicators of the two groups at baseline and after 1.5 and 3 months of treatment, including Young’s modulus value of the medial gastrocnemius muscle at rest, the modified Ashworth scale (MAS) score, and the clinical spasm index (CSI) score. The changes in muscle tone and spasticity of SCP children before and after treatment were compared, and the differences in the Young’s modulus between MAS and CSI levels in SCP children as well as the correlation between MAS, CSI, and Young’s modulus were analyzed.Results:The difference in Young’s modulus values of the control group at baseline, after 1.5 and 3 months of treatment was not statistically significant (all P > 0.05). At baseline, after 1.5 and 3 months of treatment, Young’s modulus value, MAS score, and total CSI score gradually decreased in the observation group, and the differences obtained from pairwise comparisons were statistically significant (all P < 0.01). At the same intervention stage, Young’s modulus value of the observation group was higher than that of the control group, with a statistically significant difference ( P < 0.01). The MAS score results showed that Young’s modulus of the observation group increased with the increase in muscle tone, and there was a positive correlation between Young’s modulus and muscle tone ( P < 0.01), and the difference in Young’s modulus corresponding to different muscle tones was statistically significant ( P < 0.05). The CSI score results showed that the Young’s modulus of the observation group increased with the increase in spasticity degree, and there was a positive correlation between the Young’s modulus and muscle tone ( P < 0.01), and the difference in Young’s modulus corresponding to different spasticity degrees was statistically significant ( P < 0.05). Conclusions:The muscle hardness of children with SCP is higher than that of normal children. The "Tongluo" technique can effectively improve muscle hardness, reduce muscle tone, and effectively improve muscle spasticity in children with SCP. The principle may be related to adjusting the internal structure of muscles to reduce muscle hardness. The results of this study can guide clinical rehabilitation and evaluation.

Background::Schizophrenia (SCZ) is a complex psychiatric disorder associated with widespread alterations in the subcortical brain structure. Hemispheric asymmetries are a fundamental organizational principle of the human brain and relate to human psychological and behavioral characteristics. We aimed to explore the state of thalamic lateralization of SCZ.Methods::We used voxel-based morphometry (VBM) analysis, whole-brain analysis of low-frequency fluctuations (ALFF), fractional amplitude of low-frequency fluctuations (fALFF), and resting-state seed-based functional connectivity (FC) analysis to investigate brain structural and functional deficits in SCZ. Also, we applied Pearson's correlation analysis to validate the correlation between Positive and Negative Symptom Scale (PANSS) scores and them.Results::Compared with healthy controls, SCZ showed increased gray matter volume (GMV) of the left thalamus ( t = 2.214, p = 0.029), which positively correlated with general psychosis ( r = 0.423, p = 0.010). SCZ also showed increased ALFF in the putamen, the caudate nucleus, the thalamus, fALFF in the nucleus accumbens (NAc), and the caudate nucleus, and decreased fALFF in the precuneus. The left thalamus showed significantly weaker resting-state FC with the amygdala and insula in SCZ. PANSS negative symptom scores were negatively correlated with the resting-state FC between the thalamus and the insula ( r = -0.414, p = 0.025). Conclusions::Collectively, these results suggest the possibility of aberrant laterality in the left thalamus and its FC with other related brain regions involved in the limbic system.
