Objective To compare the clinical characteristics of pneumococcal meningitis in different age groups, and to provide a basis for early diagnosis of pneumococcal meningitis. Methods Cerebrospinal fluid and/or serum samples were collected from 1742 suspected cases of meningitis in Baoji, Shaanxi Province from August 2013 to July 2019. Streptococcus pneumoniae was detected by isolation culture and real-time fluorescence quantitative polymerase chain reaction. Retrospective analysis of clinical manifestations, biochemical indicators and other information of laboratory confirmed cases was conducted by χ² test or Fisher's exact test. Results A total of 1742 samples of encephalitis or meningitis cases were detected, and 41 cases were confirmed as laboratory-confirmed Streptococcus pneumoniae infection. Among them, there were 12 cases (29.27%) in the infant group, 14 cases (34.15%) in the child group, and 15 cases (36.59%) in the adult group. The proportion of the adults with headache was significantly higher than that of the infants (χ²=11.408，P＜0.017). The proportion of the adults with consciousness disorder, elevated white blood cells and elevated neutrophils were significantly higher than those in the infant and the child groups（Fisher's exact test, P＜0.017；χ² =6.428，P＜0.017；χ² =10.898，P＜0.017；χ² =6.421，P＜0.017；χ² =9.758，P＜0.017；χ² =7.744，P＜0.017). The proportion of the infants with cerebrospinal fluid turbidity was significantly higher than that of the children (Fisher's exact test，P＜0.017). The proportion of the infants with decreased white blood cells and reduced glucose in cerebrospinal fluid was significantly higher than that of the children group and the adult group（Fisher's exact test, P＜0.001；Fisher's exact test, P＜0.001；Fisher's exact test, P＜0.017; Fisher's exact test, P＜0.017). Conclusion Most adult patients with pneumococcal meningitis have headache and consciousness disorders, with significantly increased proportion of white blood cells and neutrophils. Infant patients tend to have cloudy appearance of cerebrospinal fluid, leukopenia in blood, and decreased glucose in cerebrospinal fluid.

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.

Respiratory syncytial virus (RSV) is a common pathogen that causes acute respiratory infections, especially in infants and young children. There are currently no RSV-specific antiviral drugs, and there are no approved vaccines for infants and young children. With the widespread use of RSV passive immunizations in infants and young children in 2022 and the effective reduction of the burden of RSV infection-related diseases, passive immune-prophylaxis of RSV infection has attracted more and more attention. This paper summarizes the implementation experience and real-world application effect of passive immune-prophylaxis for RSV infection at home and abroad, to provide reference for the immune-prophylaxis practice of passive immune-prophylaxis for RSV infection in infants and young children in China.

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.

Objective:To investigate the current status of pertussis laboratory diagnosis and confirmed pertussis cases reporting in Shaanxi Province, and evaluate the quality of case reports.Methods:The information of confirmed pertussis cases reported in Shaanxi Province from January to July 2022 was collected through the China Disease Control and Prevention Information System. The laboratory diagnostic methods and pertussis vaccine immunization history of confirmed cases were investigated, and the descriptive epidemiological method was used for statistical description.Results:Of the 164 confirmed cases of pertussis reported from January to July 2022, two were not tested in the laboratory and 162 were tested in the laboratory. The proportions of different detection methods were 1.85% (3/162) of isolation and culture, 31.48% (51/162) of serum antibody IgG, 14.20% (23/162) of serum antibody IgM, 49.38% (80/162) of serum antibody PCR and 3.09% (5/162) of serum antibody IgM+ PCR. Among the 79 serological positive cases, 12 cases (15.19%)had no history of pertussis immunization, and 15 cases (18.99%), 11 cases (13.92%) and 41 cases (51.90%) had the time interval from vaccination to detection of <1 year, 1-3 years and >3 years, respectively. Based on the analysis of laboratory testing methods and vaccination history, 38 cases were misdiagnosed/misreported among 164 cases, with a misdiagnosis or misreported rate of 23.17%. There were 17, 12 and 9 cases of misdiagnosis/misreport in 0-2 years old group, 3-6 years old group and≥7 years old group, and the misdiagnosis or misreported rates were 27.42%(17/62), 26.67%(12/45) and 15.79%(9/57), respectively.Conclusions:The selection of pertussis laboratory testing methods in some medical institutions in Shaanxi Province is incorrect, which leads to a certain proportion of misdiagnosis or misreport, and it is necessary to further strengthen the training and standardization.
