Objective To analyze the epidemiological characteristics of statutory infectious diseases in Yichang City from 2015 to 2023 and evaluate the effectiveness of non-pharmaceutical interventions (NPIs) in infectious disease prevention and control, and to provide a basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze annual incidence rates. SARIMA and SARIMA intervention models were constructed to predict the incidence rates of infectious diseases. Interrupted time series analysis (ITS) was applied to assess the control effectiveness. Results The average annual incidence rate from 2015 to 2023 was 787.47/100 000, with the top five diseases being influenza, hand-foot-and-mouth disease, hepatitis B, tuberculosis, and diarrheal diseases. The average incidence rate from 2015 to 2019 (654.31/100 000) was significantly higher than that from 2020 to 2022 (489.01/100 000) (χ²= 3 499.6, P < 0.05). The total incidence rate in 2023 (2 396.51/100 000) was significantly higher than the average annual incidence rates from 2015-2019 (χ²= 108 186.1, P < 0.05) and 2020-2022 (χ²= 112 869.4, P < 0.05). SARIMA model results indicated that the actual incidence rate from 2020 to 2022 decreased by 73.49% compared to the predicted rate without intervention, with the highest decline observed in respiratory infectious diseases (79.57%). The SARIMA-intervention model showed a 55.48% relative decrease in the total incidence rate for 2023, with the largest reduction in respiratory infectious diseases (63.28%) and a slight increase in intestinal infectious diseases (5.48%). Conclusion NPIs effectively reduce the incidence of statutory infectious diseases in the short term, especially for acute respiratory and intestinal infectious diseases. However, long-term effectiveness faces challenges, necessitating the development of differentiated prevention and control strategies.

Objective To elucidate the changes in the gut microbiota and molecular mechanism of huaier in enhancing the efficacy of oxaliplatin (OXA) chemotherapy in gastric cancer (GC). Methods The effects of huaier on the gut microbiota structure and intestinal barrier function in MKN45-bearing mice were analyzed by using 16S rRNA sequencing, RT-qPCR, and IHC. UPLC-MS and network pharmacology, as well as in vivo experimental approaches, were employed to investigate the key bioactive constituents of huaier systematically and elucidate the underlying mechanisms by which huaier exerts therapeutic effects against GC. The expression of the PI3K/AKT/SREBP pathway was detected in cancer cells and tissues via Western blot analysis. The safety profile of huaier combined with OXA was verified through serum biochemistry and HE-stained tissue section analyses. Results Huaier inhibited the PI3K/AKT/SREBP pathway by increasing the abundance of Akkermansia muciniphila, reduced lipid droplet deposition, and ultimately enhanced the sensitivity to OXA in the treatment of GC. Conclusion This study demonstrates the value of huaier in gastric cancer treatment by enhancing chemosensitivity and provides novel insights into its systemic therapeutic effects through molecular mechanisms and gut microbiota modulation.

Objective:To explore the epidemiological characteristics, clinical manifestations, laboratory findings, and imaging features of children with HRV-associated pneumonia, and to analyze the clinical features and risk factors associated with severe HRV pneumonia, providing references for clinical management.Methods:A single-center, retrospective, observational study was conducted, including 1 001 cases of HRV-positive children with pneumonia admitted to the Respiratory Department of the Affiliated Children′s Hospital of Capital Institute of Pediatrics from January 2019 to December 2023. Among them, 584 cases (58.3%) were male and 417 cases (41.7%) were female, with an age range of 0.1 to 14.9 years, a median age of 3.42 years, and a mean age of (3.92±2.75) years. According to clinical guidelines, the cases were divided into a mild pneumonia group (855 cases, 510 males, 345 females) and a severe pneumonia group (146 cases, 73 males, 73 females). Basic information, clinical, laboratory, and imaging data were collected from the electronic medical record system. Comparisons between different age groups, diagnoses, and pneumonia severity groups were performed using the χ2 test. Multivariate logistic regression analysis was used to identify risk factors for the severity of HRV pneumonia. Results:Among the 1 001 cases of HRV-associated bronchopneumonia, 146 cases (14.6%) were severe pneumonia. The age of severe HRV pneumonia patients was significantly higher than that of the mild pneumonia group (5.2 years vs. 3.7 years, t=-6.050, P<0.01). Severe HRV pneumonia had a higher incidence in autumn and winter (60.9%). Severe HRV pneumonia was associated with higher levels of lactate dehydrogenase (LDH), C-reactive protein (CRP), neutrophils, and creatinine (correlation coefficients 0.198, 0.334, 0.104, 0.142, P<0.01), and lower levels of albumin (correlation coefficient 0.308, P<0.01). Multivariate logistic regression analysis showed that co-infection with Streptococcus pneumoniae or Mycoplasma was an independent risk factor for severe HRV pneumonia [ OR=1.611, 95% confidence interval ( CI):1.066-2.435, P<0.05; OR=3.355, 95% CI:2.062-5.458, P<0.01]. Conclusion:The infection rate of HRV is higher in preschool and school-age children. Severe HRV pneumonia is associated with increased levels of LDH, CRP, neutrophils, and creatinine, as well as decreased levels of albumin. Co-infection with Streptococcus pneumoniae or Mycoplasma may be an independent risk factor for severe HRV pneumonia. High-risk children require enhanced monitoring and early intervention to improve prognosis.

Objective:To analyze the effectiveness of multicomponent exercise (ME) in old adults, and provide reference for the promotion of healthy aging.Methods:Literature on ME intervention for old adults published until February 29, 2024 were retrieved from Web of Science, PubMed, Scopus, Embase, EBSCO, Cochrane Library, CNKI, Wanfang Data, and VIP Database. After screening and evaluation, an umbrella review was conducted.Results:In total, 15 systematic reviews and Meta-analyzes (193 randomized controlled trials and 19 203 participants) were included. The umbrella review suggested that the average standardized mean difference ( SMD) affecting physical function/health of ME was between 0.40 and 1.00, the average SMD affecting brain health was between -0.30 and 1.60, the average SMD affecting mood/mental health was between 0.01 and 0.20, and the average SMD affecting quality of life was between -0.20 and 0.40. Effects of ME on lower limb strength [mean difference ( MD)=1.1] and aerobic capacity ( MD=0.8) were better compared with general strength exercise and aerobic exercise respectively. Effects of ME on cognitive function ( MD=0.99) were better compared with strength exercise ( MD=0.84), aerobic exercise ( MD=0.77), and mind-body exercise ( MD=0.63). Effects of ME on executive function ( MD=0.72) were better compared with aerobic exercise ( MD=0.62), strength exercise ( MD=0.44), and mind-body exercise ( MD=0.36). Effects of ME on activity of daily living ( SMD=0.32) were better compared with strength exercise ( SMD=0.12). Conclusions:ME can clearly improve the physical function/health and brain health in old adults. The impact varies with different participants, exercise program designs, and assessment methods. However, its effect on mood/mental health and the quality of life still need further verification. ME might show better effects compared with general single component exercise (such as strength exercise, aerobic exercise) and mind-body exercise in improving lower limb strength, aerobic capacity, cognitive function, executive function, and activity of daily living in specific elderly populations. Given the impact of the quantity, quality and heterogeneity of the reviews included, the conclusions mentioned above still need validation in practice.

Objective:To explore the current status of perceived vulnerability and its influencing factors among parents of children with type 1 diabetes mellitus (T1DM) .Methods:A convenience sampling method was used to select 220 parents of children with T1DM from the diabetes care and consultation outpatient clinic at Beijing Children's Hospital, Capital Medical University, from June to November 2023. The parents were surveyed using a general information questionnaire, the Parental Perceived Vulnerability Scale, the Family Care Index, and the Parental Illness Uncertainty Scale.Results:A total of 220 questionnaires were distributed, with 192 valid responses. The total score on the Parental Perceived Vulnerability Scale was (13.91±5.39), the total score on the Family Care Index was (5.39±2.73), and the total score on the Parental Illness Uncertainty Scale was (75.36±17.34). Multiple linear regression analysis showed that whether the child was an only child, family monthly income per capita, parents' religious beliefs, family care level, and illness uncertainty were significant influencing factors for perceived vulnerability ( P<0.05), explaining 36.5% of the variance. Conclusions:Healthcare professionals should pay more attention to parents who have only children, have lower family income, and do not have religious beliefs. Interventions aimed at improving family care levels and reducing illness uncertainty may help decrease the perceived vulnerability among parents of children with T1DM.

Acupuncture and moxibustion have their unique advantages in treating tumors,but the theoretical framework of acupuncture and moxibustion intervention in tumors needs to be improved,and the academic system still needs to be sorted out.In this paper,we try to describe the commonalities between Chinese medical theories and modern medical technologies in order to consolidate the theoretical foundation of acupuncture intervention in tumor.Specifically:① Acupuncture regulates immune function and energy metabolism,which is a specific form of tonifying the spleen and stomach to support positive qi.② Tumors belong to the broad definition of"sores and ulcers"in traditional Chinese medicine,which is a special kind of chronic inflammation,and acupuncture intervenes in tumors by intervening in inflammatory reactions from ulcers.③ Tumor is a"dynamic pseudo-organ"with yin and yang attributes and"life attributes".Acupuncture and moxibustion can regulate various cells and factors in the tumor environment in a multi-targeted way,so as to make it tend to the state of yin and yang equilibrium.④ Acupuncture and moxibustion have unique advantages in the reduction of toxicity,enhancement of efficacy,tonicity,rejuvenation,treatment of complications,etc.,which complement the allopathic therapies of modern medicine,and can help to realize survival with tumors.

Platelet transfusion refractoriness (PTR) is a common issue among patients with hematological diseases and tumors. This article reviews the diagnostic criteria, influencing factors, and recent prevention and management strategies for immune PTR. The diagnostic criteria typically involve post-transfusion platelet increment (PI), platelet recovery rate (PPR), and corrected count increment (CCI). Both immune and non-immune factors can lead to PTR, with immune factors mainly including HLA and HPA antibodies. Prevention and management strategies include the use of leukocyte-reduced platelets, HLA and HPA antigen-matched platelets, intravenous immunoglobulin therapy, and immunosuppressive strategies. Although various strategies have been proposed and applied in clinical practice, the prevention and management of immune PTR remain challenging. Future research needs to explore more effective individualized treatment strategies, while also considering the potential application of emerging technologies such as nanotechnology in the field of transfusion.

Objective:To explore the regulatory mechanisms underlying the weak expression of ABO blood group antigens due to variants in the non-coding regions of the ABO gene. Methods:From June 2014 to October 2023, a total of 29 samples from the Taiyuan Blood Center and local hospitals, which were serologically identified as having weak ABO antigen expression without detectable coding region mutations, were selected for this study. Full-length ABO gene sequencing was performed using third-generation long-read sequencing technology (Pacific Biosciences) to obtain complete haplotype sequences of the ABO gene. Variants in the non-coding regions were compared and identified to infer their regulatory effects on weak antigen expression. The procedures followed in this study were in accordance with the ethical standards of the World Medical Association′s Declaration of Helsinki (2013 revision). The Medical Ethics Committee of Taiyuan Blood Center has granted an exemption from ethical review. Results:18 bp deletions in the -35 to -18 region of the promoter were identified in 7 samples. Variants in intron 1 (+ 5.8 kb) were detected in 7 samples, including ABO* A (28+ 5792_5793delCT (1 case) and ABO* B (28+ 5793T>C) located in the GATA binding region; ABO* B (28+ 5808C>T) (1 case) in the E-box region; and ABO* B (28+ 5875C>T) (4 cases) in the RUNX1 binding region. Nucleotide variants at splice sites were detected in 2 samples, namely ABO* B (C.98+ 1G>A) and ABO* B (C.204-2A>C). Conclusion:Variants in the non-coding regulatory sequences of the ABO gene are a significant factor contributing to weak ABO antigen expression. In clinical ABO sequencing, it is essential to screen not only the conventional coding regions but also the flanking sequences, introns, and splice sites of the ABO gene to facilitate precise blood transfusion.

Objective:To report the blood group antigen and antibody specificity identification methods for a patient with high-frequency antibodies, and the process of finding and providing compatible blood for the patient.Methods:A patient sent from the Blood Transfusion Department of Shanxi Provincial People′s Hospital to Taiyuan Blood Center in November 2022 was selected for the study. Classical serological methods were used to determine the patient′s blood type, screen for unexpected antibodies, identify antibodies, and perform crossmatching. High-frequency antibody identification was carried out using red blood cells treated with various enzymes. Blood group genotyping was conducted using Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF) and Sanger sequencing. Multiple strategies were employed to address the patient′s blood source problem. The study was approved by the Medical Ethics Committee of Taiyuan Blood Center [Ethics No. 2024 Ethics Review No.(2)].Results:①The patient′s blood type was B, RhD positive. Initial screening of the patient′s serum with multiple screening cells and antibody identification cells in saline medium was negative, but positive in antiglobulin medium. The patient′s serum showed varying reaction intensities with red blood cells treated with different enzymes. ②MALDI-TOF mass spectrometry and Sanger sequencing revealed a homozygous nonsense variant c. 376C>T (p.Gln126Ter) in the ABCG2 gene, resulting in the Jr(a-) phenotype. During family donor selection, the patient′s son was found to have a heterozygous variant c. 376C>T (p.Gln126Ter), and another heterozygous variant c. 421C>A (p.Gln141Lys), which predicted a Jr(a+ w) phenotype. ③Crossmatch tests confirmed the compatibility of blood from the patient′s son, which was used to address the urgent blood requirement. Later, rare blood from a Jr(a-) donor from the Guangzhou Blood Center was used for the patient′s ongoing treatment, saving the patient′s life. Conclusion:Combining classic serological testing with blood group gene typing techniques successfully identified the rare Jr(a-) blood type and high-frequency anti-Jra antibodies. Enzyme-treated red blood cell identification methods confirmed the presence of anti-Jra antibodies. By searching within the family and seeking help from other blood centers, compatible blood was found. This approach may provide insights for resolving similar complex blood matching problems in the future.
