Objective:To analyze the vaccination recommendations and follow-up for children with special health status.Methods:In this retrospective cohort study, 509 children who attended the Consultation Clinic of Vaccination for Special Health Children in Beijing Children′s Hospital from August 2020 to February 2023 were selected, the children were given vaccination planning advice after the assessment. The clinical data were collected, including the general situation, special health conditions, vaccination recommendations and implementation status, occurrence and outcomes of suspected adverse events following immunization (AEFI) after vaccination. The vaccination situation and safety in these children were evaluated.Results:Among the 509 children, the most common special health conditions were cardiovascular system diseases (103 cases), followed by neurological diseases (88 cases) and neonatal problems (82 cases). After comprehensive evaluation and multidisciplinary collaboration, 399 children (78.4%) were recommended to receive vaccination/catch-up vaccination according to the immunization program, 63 children (12.4%) were recommended to receive some vaccines but temporarily suspend others, and 47 children (9.2%) were recommended to temporarily suspend vaccination. A total of 449 children (88.2%) were actually vaccinated, AEFI occurred in 49 children and 45 cases were considered as general reactions.Conclusions:The majority of children with special health status can be vaccinated, and the overall compliance and safety are high. The individualized immunization evaluation model of multidisciplinary collaboration is conducive to the completion of the immunization program of children with special health status.

Objective:To investigate the clinical effect of free anterolateral thigh perforator flap(ALTPF) in reconstruction of temporal scalp defect after blood circulation reconstruction surgery for moyamoya disease.Methods:From May 2020 to July 2022, 7 patients with scalp defect after revascularisation of moyamoya disease were treated in Department of Hand and Foot Microsurgery, Henan Provincial People’s Hospital (People’s Hospital of Zhengzhou University). The patients were 4 males and 3 females, aged 33-59 years old, at 43 years old in average. There were 5 defects in left tempus and 2 in right tempus. The sizes of scalp defect were 4.5 cm × 5.5 cm-7.5 cm × 9.5 cm. Debridement and VSD management were primarily performed. After wounds were stabilised, ultrasound location of perforator vessels of ALTPFs was performed. Having confirmed that the perforator vessels were suitable for the surgical requirements, flap transfers were then performed. The descending branch of the lateral femoral circumflex artery was end-to-side anastomosed with the superficial temporal artery, and the descending branch of the lateral femoral circumflex vein was end-to-end anastomosed with the superficial temporal vein. Postoperative follow-up was conducted through outpatient clinic visits, telephone and WeChat reviews. Appearance, texture of ALTPFs and the flap donor sites were observed in follow-ups. Comparisons of the changes of nervous system before and after surgery were made. Cognitive function of the patients was assessed with the Mini Mental State Examination (MMSE), together with the Activities of Daily Living (ADL) .Results:All 7 flaps survived. One flap had vascular compromise 6 hours after surgery, and was rectified after surgical intervention. All the patients were included in the postoperative follow-up for 7-33 (average 19) months. All flaps had good appearance with soft texture. There was no obvious difference in colour comparing with the skin around the recipient region. The donor sites healed well without hypertrophic scar. Examinations of nervous system of the patients were found the same as that before surgery. Using Manual Muscle Testing (MMT), the average limb muscle strength of the patients was 4 before surgery and 4 after surgery, without change; Using the Ashworth assessment scale, the average preoperative and postoperative limb muscle tension in this group of patients was 1, without change; The Berg balance scale was used to evaluate the patient's balance function, with an average score of 42 before surgery and 42 after surgery, without any changes; There was no change in limb sensation before and after surgery; Using the MMSE, the average preoperative score and postoperative score of this group of patients were 25 points, without any change. Using the modified Barthel index scoring standard, the average preoperative score for this group of patients was 75 points, and the average postoperative score was 79 points, and the ADL of the patient had improved to various levels.Conclusion:Reconstruction of scalp defect with free ALTPF after revascularisation of moyamoya disease has obvious advantages, such as it closes the wound quickly, prevents infection and achieves a good appearance. This surgical procedure can produce a good clinical effect.

ObjectiveTo investigate the situation and development trend of the disease burden of acute hepatitis B in China in 1990 — 2019. MethodsThe Global Burden of Disease 2019 was used to analyze the incidence rate， mortality rate， and disability-adjusted life year （DALY） rate of acute hepatitis B in different sex and age groups and predict the trend of the incidence rate of acute hepatitis B. ResultsIn 2019， the incidence rate， mortality rate， and DALY rate of acute hepatitis B in China were 1 623.71/100 000， 0.20/100 000， and 10.04/100 000 respectively， which were reduced by 42.03%， 79.38%， and 80.21%， respectively， compared with the data in 1990， and women showed lower incidence rate， mortality rate， and DALY rate of acute hepatitis B than men. In 2019， the 20～<54 years group had the highest incidence rate （2 285.85/100 000） and DALY rate （10.53/100 000）， and the ≥55 years group had the highest mortality rate of 0.52/100 000. The Joinpoint regression model analysis showed that the incidence rate， mortality rate， and DALY rate of acute hepatitis B in China tended to decrease from 1990 to 2019， with an average annual percent change of -1.9%， -5.2%， and -5.5%， respectively （P<0.05）. The grey prediction model GM （1，1） showed that the incidence rate of acute hepatitis B will decrease from 2020 to 2030 in China. ConclusionThe disease burden of acute hepatitis B tended to decrease from 1990 to 2019 in China， indicating that the prevention and treatment measures for acute hepatitis B have achieved a marked effect in China； however， due to the large population base of China， active preventive measures should be further adopted to reduce the disease burden of acute hepatitis B.

Primary central nervous system lymphoma (PCNSL) is an uncommon non-Hodgkin's lymphoma with poor prognosis. This study aimed to depict the genetic landscape of Chinese PCNSLs. Whole-genome sequencing was performed on 68 newly diagnosed Chinese PCNSL samples, whose genomic characteristics and clinicopathologic features were also analyzed. Structural variations were identified in all patients with a mean of 349, which did not significantly influence prognosis. Copy loss occurred in all samples, while gains were detected in 77.9% of the samples. The high level of copy number variations was significantly associated with poor progression-free survival (PFS) and overall survival (OS). A total of 263 genes mutated in coding regions were identified, including 6 newly discovered genes (ROBO2, KMT2C, CXCR4, MYOM2, BCLAF1, and NRXN3) detected in ⩾ 10% of the cases. CD79B mutation was significantly associated with lower PFS, TMSB4X mutation and high expression of TMSB4X protein was associated with lower OS. A prognostic risk scoring system was also established for PCNSL, which included Karnofsky performance status and six mutated genes (BRD4, EBF1, BTG1, CCND3, STAG2, and TMSB4X). Collectively, this study comprehensively reveals the genomic landscape of newly diagnosed Chinese PCNSLs, thereby enriching the present understanding of the genetic mechanisms of PCNSL.

Objective:To summarize the clinical characteristics, common images, pathogens, and gene mutation types of chronic granulomatosis disease (CGD) in 19 children.Methods:The clinical manifestations, laboratory findings, treatment, and prognosis of 19 patients diagnosed with CGD in Hong Kong University-Shenzhen Hospital from December 2012 to December 2018 were analyzed.Results:The 19 patients were all males and confirmed as CGD by the dihydrorhodamine test and gene sequencing.The age of the first infection was mostly 1 month after birth(13 cases), and the age of clinical diagnosis ranged from 2 months to 10 years.Sixteen mothers were carriers.The patients presented with pulmonary fungal infection (19/19 cases), Bacillus Calmette Guerin (BCG)-osis (14/19 cases), lymphadenitis (14/19 cases), perianal abscess (9/19 cases), skin abscess (5/19 cases) and ulcerative colitis (2/19 cases). There were 59 positive cultures.Pathogens included fungi (9 cases), Klebsiella pneumonia (8 cases), mycobacteria (7 cases), Streptococcus Viridans (5 cases), Escherichia coli (3 cases), gram-positive bacteria (3 cases), Staphylococcus aureus (3 cases), and Burkholderia cenocepacia (2 cases). Gene mutations were found in all 19 patients, including 17 cases of CYBB, 1 case of CYBA and 1 case of NCF2.The type of mutations included nonsense mutations (6 cases), deletion mutations (5 cases, including 2 large fragment deletions), splice mutations (3 cases) and missense mutations (5 cases). Five mutations were novel.Splice mutations in 3 cases often led to skin abscess, perianal abscess and lymphadenitis.Two patients with large deletion mutations had more serious infection than other patients. Conclusions:In China, CGD is characterized with pulmonary infection and disseminated BCG-osis.Mycobacteria are common pathogens of CGD, and fungi are dominant pathogens of CGD.The most common infection is respiratory infection. Klebsiella pneumonia and Escherichia coli often lead to perianal abscess.The relationship between gene mutation types and clinical phenotypes requires further verification by big data.

Objective:To investigate the changes of brain energy metabolism and cognitive function in mice with specifically knocking out AMP-activated protein kinase α1 subunit ( AMPKα1) gene in the excitatory neurons by Cre-loxP recombination system. Methods:Sixteen 6-month-old mice with genotype AMPKα1 flox/flox/Camk2a-Cre/ERT2 obtained by hybrid breeding were randomly divided into AMPKα1 knockout group ( n=8) and AMPKα1 wild-type group ( n=8). Mice in the AMPKα1 knockout group were intraperitoneally injected 0.1 mL tamoxifen (20 mg/mL, dissolved in corn oil) daily for a consecutive 5 d to control AMPKα1 gene knockout in the excitatory neurons; and mice in the AMPKα1 wild-type group were intraperitoneally injected 0.1 mL corn oil daily for a consecutive 5 d. Seven d after that, Morris water maze and T maze experiments were employed to detect the spatial learning and memory abilities and spatial working memory of these mice; chemical exchange saturation transfer imaging (CEST) was used to observe the glucose metabolism in the hippocampus and cortex surrounding the hippocampus; Western blotting was used to detect the AMPKα1 and glutamate receptor 1 (GluR1) protein expressions in the hippocampus and cortex surrounding hippocampus of two groups. Results:(1) Morris water maze showed that, as compared with those in the AMPKα1 wild-type group, mice in the AMPKα1 knockout group had significantly prolonged escape latency ([13.90±3.72] s vs. [22.40±6.28] s; [11.95±3.86] s vs. [22.39±9.77] s]) on the 3 rd and 4 th d of experiment, statistically decreased times crossing the platform ([5.25±1.83] times vs. [1.75±1.28] times, P<0.05). (2) T-maze experiment showed that as compared with that of the AMPKα1 wild-type group, the free alternation rate in mice of the AMPKα1 knockout group was significantly decreased ([73.21±9.16]% vs. [48.21±11.29]%, P<0.05). (3) CEST showed that the glucose metabolism levels in the hippocampus and cortex surrounding the hippocampus of AMPKα1 knockout group were significantly lower than those in AMPKα1 wild-type group (1.51±0.81 vs. 2.77±0.67; 1.31±0.83 vs. 2.42±0.95, P<0.05). (4) Western blotting showed that the AMPKα1 and GluR1 protein expressions in the hippocampus and cortex surrounding the hippocampus of the AMPKα1 wild-type group were significantly higher than those of the AMPKα1 knockout group (AMPKα1: 0.70±0.05 vs. 0.49±0.03, 0.98±0.04 vs. 0.64±0.06; GluR1: 1.22±0.18 vs. 0.60±0.11, 0.96±0.08 vs. 0.79±0.04, P<0.05). Conclusion:Specifically knocking out AMPKα1 in excitatory neurons can result in abnormal glucose metabolism in the brain of mice, and thus cause cognitive dysfunction, whose mechanism may be related to excitatory synaptic disorder caused by energy metabolism disorder.

Objective:To investigate the relationship between caspase recruitment domain protein 9 (CARD9) level and inflammatory response in cerebral tissue of ischemic brain injury mice.Methods:Totally 24 SPF BALB/c male mice were randomly(random number) divided into 4 groups: sham operated group, ischemia 3 h group, ischemia 6 h group, and ischemia 12 h group, 6 mice in each group. The permanant middle cerebral artery occlusion (pMCAO) model in the ischemia groups was established by using line embolism to block blood flow. Mice in each group were sacrificed at the predetermined time point after operation. CARD9 and p-p65NF-κB levels were detected by Western blot, and the inflammatory factors mRNA and protein including TNF-ɑ, IL-lβ and IL-6 were detected by RT-PCR and ELISA, respectively. The data were analyzed by SPSS 21.0 software, the comparison of measurement data between each two groups was analyzed by independent sample t test, and the correlations between CARD9 and inflammatory factors were analyzed by Pearson analysis. Results:Compared with the sham operated group, the CARD9 levels in the ischemia 3 h, 6 h and 12 h groups were increased significantly [(0.325±0.011) vs. (0.462±0.019), P=0.036; (0.735±0.036), P=0.003; (0.903±0.024), P=0.001], the p-p65NF-κB levels in the ischemia 3 h, 6 h and 12 h groups were increased significantly [(0.227±0.016) vs. (0.316±0.017), P=0.041; (0.445±0.021), P=0.016; (0.671±0.039), P=0.008], the TNF-ɑ levels in the ischemia 3 h, 6 h and 12 h groups were significantly increased [(0.53±0.06) vs. (1.06±0.10), P=0.009; (1.47±0.15), P=0.004; (2.78±0.18), P=0.001], the IL-lβ levels in the ischemia 3 h, 6 h and 12 h groups were significantly increased [(0.55±0.07) vs. (1.01±0.11), P=0.009; (2.13±0.16), P=0.003; (3.09±0.18), P=0.001], and the IL-6 levels in the ischemia 3 h, 6 h and 12 h groups were significantly increased [(1.99±0.18) vs. (4.10±0.41), P=0.006; (8.54±0.84), P=0.002; (11.56±0.96), P=0.001]. Pearson analysis showed that CARD9 was positively correlated with the p-p65NF-κB and TNF-ɑ, IL-lβ, IL-6 ( r=0.894, P=0.001; r=0.747, P=0.008; r=0.810, P=0.001; r=0.773, P=0.007). Conclusions:A positive correlation exists between CARD9 and inflammatory responses in the early stage of ischemic brain injury in mice

Objective: To explore the relationship among social support, self-efficacy, peer pressure and physical exercise behavior and to provide a reference for subjective initiative of college students in physical exercise. Methods: Questionnaire survey regarding social support, peer pressure and self-efficacy, as well as physical exercise behavior was administered among 1 189 students from 3 colleges and universities in Henan Province during August to October 2019. Results: Peer pressure score was (18.72±4.02), subjective support score was (14.76±3.46), objective support score was (10.98±2.53), utilization score for support was (11.20±3.12), self-efficacy score was (36.79±8.00), physical exercise behavior score was (21.72±4.75). Subjective support, objective support, utilization of support, peer pressure, self-efficacy and college students ’ physical exercise behavior were significantly positively correlated(P<0.05). Structural equation model showed that subjective support, objective support, utilization of support, peer pressure, and self-efficacy significantly positively associated with physical exercise behavior,with standardization coefficients of 0.08, 0.12, 0.13, 0.40, 0.90(P<0.05), respectively. Self-efficacy has significant mediating effect on peer pressure, subjective support, objective support, utilization of support and physical exercise behavior of college students used, with standardized effect quantities being 55.36%, 90.73%, 85.88%, 87.92%, respectively. Conclusion College students’ physical exercise behavior is closely related to social support, peer pressure and self-efficacy. Social support has a significant impact on college students’ physical exercise behavior, and self-efficacy, while self-efficacy and peer pressure all have a positive effect on college students’ physical exercise behavior.
