Objective To understand the epidemiological characteristics and current status of pertussis in Jingzhou City from 2013 to 2024. Methods Data on reported pertussis cases in Jingzhou City (2013–2024) and hospitalized pertussis cases from two medical institutions (January–May 2024) were collected for descriptive epidemiological analysis. Results A total of 1 553 pertussis cases were reported in Jingzhou City from 2013 to 2024. The average annual incidence rate from 2013 to 2023 was 0.12/100 000, and that in 2024 was 28.86/100 000. The incidence peaked in spring and summer. High-incidence areas included Jingzhou District, Shashi District, and Jiangling County. There was no difference between men and women. The highest incidence occurred in the 0-year-old group, primarily among students, scattered children, and childcare attendees. Hospitalized cases exhibited milder and atypical symptoms. Age>2 months, and admission for treatment at the first visit were the protective factors for severe pertussis, while having a history of patent foramen ovale was the risk factor for severe pertussis. Conclusion Jingzhou City experienced a rapid and significant rise in pertussis incidence in 2024. Prevention and control measures in childcare facilities and schools should be prioritized during spring and summer. Enhancing laboratory testing in medical institutions can facilitate early diagnosis and treatment. Adjusting vaccination strategies for young infants and older children is critical to reducing both incidence and severe case rates.

Xiaoaiping (XAP) Injection demonstrates the anti-prostate cancer (PCa) effects, yet the underlying mechanism remains unclear. This study aims to investigate the impact of XAP on PCa and elucidate its mechanism of action. PCa cell proliferation was evaluated using a cell counting kit-8 (CCK-8) assay. Cell apoptosis was assessed through Hoechst staining and Western blotting assays. Proteomics technology was employed to identify key molecules and significant signaling pathways modulated by XAP in PCa cells. To further validate potential key genes and important pathways, a series of assays were conducted, including acridine orange (AO) staining, transmission electron microscopy, and immunofluorescence assays. The molecular mechanism of XAP against PCa in vivo was examined using a PC3 xenograft mouse model. Results demonstrated that XAP significantly inhibited cell proliferation in multiple PCa cell lines. In C4-2 and prostate cancer cell line-3 (PC3) cells, XAP induced cellular apoptosis, evidenced by reduced B-cell lymphoma 2 (Bcl-2) levels and elevated Bcl-2-associated X (Bax) levels. Proteomic, immunofluorescence, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) investigations revealed a strong correlation between forkhead box O3a (FoxO3a) autophagic degradation and the anti-PCa action of XAP. XAP hindered autophagy by reducing the expression levels of autophagy-related protein 5 (Atg5)/autophagy-related protein 12 (Atg12) and enhancing FoxO3a expression and nuclear translocation. Furthermore, XAP exhibited potent anti-PCa action in PC3 xenograft mice and triggered FoxO3a nuclear translocation in tumor tissue. These findings suggest that XAP induces PCa apoptosis via inhibition of FoxO3a autophagic degradation, potentially offering a novel perspective on XAP injection as an effective anticancer therapy for PCa.

Objective To investigate the status quo of pain catastrophizing(PC)in the patients with di-abetic peripheral neuropathic pain(DPNP),and to analyze the influencing factors to provide reference for for-mulating clinical preventive intervention strategies.Methods A total of 206 patients with DPNP admitted and treated in the People's Hospital of Guangxi Zhuang Autonomous Region were selected as the research sub-jects by convenience sampling method.The general data questionnaire,Numerical Rating Scale(NRS),Pain Catastrophizing scale(PCS),Perceived Social Support Scale(PSSS)and diabetes distress scale(DDS)were used to conduct the investigation.Results The incidence rate of PC in 206 cases of DPNP patients was 44.66％(92/206),and the total score of PCS was(30.10±5.16)points.The results of multiple linear regres-sion analysis showed that the gender,duration of diabetes(≥10 years),multiple drug use,number of compli-cations(＞5),NRS score,PSSS score and scores of DDS dimensions were the main influencing factors of PC(all P＜0.05),which could explain 92.3％of the total variation of PC.Conclusion The PC incidence rate in the patients with DPNP is high.Clinical healthcare workers should pay attention to the evaluation of PC in these patients,and formulate the scientific and effective targeted intervention measures according to the main influen-cing factors to help the patients to reduce the pain burden in order to reduce the level of PC.

Aim To explore the correlation between carotid atherosclerosis(CAS)and neutrophil/lymphocyte ratio(NLR)in patients with early morning hypertension,and to construct a line chart model to predict the risk of CAS in patients with hypertension in the morning.Methods 255 patients with early morning hypertension hospitalized in the Affiliated Hospital of Chengde Medical College from October 2019 to November 2022 were collected,and their basic data,blood routine and blood biochemical indexes were collected.All selected patients need to improve 24-hour ambulatory blood pressure monitoring and carotid artery color ultrasound detection.According to the presence or absence of CAS,all selected patients were divided into morning hypertension with CAS group(n=197)and morning hypertension without CAS group(n=58).Multivariate Logistic regression analysis was used to explore the risk factors of early morning hypertension with CAS,and to construct and verify an individual line chart model to predict the risk of early morning hypertension pa-tients with CAS.Results The age,NLR,neutrophils(NE),monocytes(MO),white blood cell(WBC),total cho-lesterol(TC),triglyceride(TG)and low density lipoprotein cholesterol(LDLC)increased in the early morning hyperten-sion with CAS group compared with those in the morning hypertension group without CAS,while the HDLC decreased(P＜0.05).The results of multivariate Logistic regression analysis showed that the age,NLR and TC were higher in the early morning hypertension with CAS group than those in the early morning hypertension without CAS group,while HDLC was lower;Age,NLR and TC were independent risk factors of early morning hypertension with CAS,while HDLC was inde-pendent protective factors of morning hypertension with CAS.Based on the results of multivariate Logistic regression anal-ysis,an individualized line chart model for predicting early morning hypertension with CAS was constructed.The area un-der the ROC curve of the line chart model was 0.853(95％CI:0.802-0.904,P＜0.01).The result of Hosmer Leme-show fit test was x2=1.665(P＞0.05).Conclusions There was a positive correlation between NLR and morning hy-pertension with CAS,and NLR was an independent risk factor for morning hypertension with CAS.The individualized line chart model based on age,NLR,TC and HDLC can effectively predict the risk of hypertension with CAS in the early morn-ing,which provides a theoretical basis for early detection and prevention of atherosclerosis.

Objective: To investigate the intake of liquid dairy products and identify its influencing factors among the fourth grade students in Nanjing City. Methods: The fourth grade students were selected as the study subjects in Nanjing City using a multi-stage random cluster sampling method in September 2020. Their general information, frequency of liquid dairy product intake one week prior to survey and mean intake amount per time were collected. According to the 2016 Dietary Guidelines for Chinese Residents, weekly intake of liquid dairy products of 2 100 g and greater was defined eligible. Factors affecting the frequency and amount of liquid dairy product intake were identified using multivariable logistic regression analysis. Results: A total of 2 268 questionnaires were allocated and 2 216 valid questionnaires were recovered, with an effective recovery rate of 97.71%. The respondents included 1 199 boys ( 54.11% ) and 1 017 girls ( 45.89% ). The frequency of liquid dairy product intake was (6.41±4.86) times per week, and the median intake amount was 1 250.00 g per week (interquartile range, 1 750.00 g per week). There were 607 students ( 27.39% ) consuming liquid dairy products of 2 100 g and greater a week, and 1 016 students ( 45.85% ) consumed liquid dairy products for 7 times and more a week. Multivariable logistic regression analysis showed that living in urban areas ( OR=1.204, 95%CI: 1.005-1.443 ), knowing nutrition labels ( OR=1.221, 95%CI: 1.021-1.460 ), periodical measurement of body weight (OR=1.486, 95%CI: 1.098-2.011) and restricted intake of sugar-containing drinks ( OR=1.264, 95%CI: 1.005-1.590 ) facilitated the intake of liquid dairy products for 7 times and more a week, and students with periodical measurement of body weight were more likely to consume liquid dairy products for 2 100 g and greater a week ( OR=1.821, 95%CI: 1.240-2.676 ). Conclusions Inadequate intake of liquid dairy products is found among the fourth grade students in Nanjing City. Residence, awareness of nutrition labels, periodical measurement of body weight, and parental restriction of sugar-containing drink intake affect the intake of liquid dairy products.

OBJECTIVE: To carry out genetic testing for a child featuring global developmental delay, abnormal liver function, congenital heart disease, and brain malformation. METHODS: Peripheral blood samples of the child and his parents were collected for the extraction of genomic DNA and trio-whole exome sequencing. Candidate variant was verified by Sanger sequencing. RESULTS: Genetic testing revealed that the child has harbored a heterozygous c.2002G>T (p.Glu668Ter) variant of the SMARCA2 gene, which was predicted to be likely pathogenic by bioinformatic analysis. His mother was found to be a low-percentage mosaic for the same variant, with a ratio of 0.054 (246/4549). CONCLUSION The child was diagnosed with Nicolaides-Baraitser syndrome resulting from maternal mosaicism for the SMARCA2 gene variant.

The mitogen-activated protein kinase (MAPK) pathway controls intestinal epithelial barrier permeability by regulating tight junctions (TJs) and epithelial cells damage. Heme oxygenase-1 (HO-1) and carbon monoxide (CO) protect the intestinal epithelial barrier function, but the molecular mechanism is not yet clarified. MAPK activation and barrier permeability were studied using monolayers of Caco-2 cells treated with tissue necrosis factor α (TNF-α) transfected with FUGW-HO-1 or pLKO.1-sh-HO-1 plasmid. Intestinal mucosal barrier permeability and MAPK activation were also investigated using carbon tetrachloride (CCl 4) administration with CoPP (a HO-1 inducer), ZnPP (a HO-1 inhibitor), CO releasing molecule 2 (CORM-2), or inactived-CORM-2-treated wild-type mice and mice with HO-1 deficiency in intestinal epithelial cells. TNF-α increased epithelial TJ disruption and cleaved caspase-3 expression, induced ERK, p38, and JNK phosphorylation. In addition, HO-1 blocked TNF-α-induced increase in epithelial TJs disruption, cleaved caspase-3 expression, as well as ERK, p38, and JNK phosphorylation in an HO-1-dependent manner. CoPP and CORM-2 directly ameliorated intestinal mucosal injury, attenuated TJ disruption and cleaved caspase-3 expression, and inhibited epithelial ERK, p38, and JNK phosphorylation after chronic CCl 4 injection. Conversely, ZnPP completely reversed these effects. Furthermore, mice with intestinal epithelial HO-1 deficient exhibited a robust increase in mucosal TJs disruption, cleaved caspase-3 expression, and MAPKs activation as compared to the control group mice. These data demonstrated that HO-1-dependent MAPK signaling inhibition preserves the intestinal mucosal barrier integrity by abrogating TJ dysregulation and epithelial cell damage. The differential targeting of gut HO-1-MAPK axis leads to improved intestinal disease therapy.

Objective: To study the clinicopathological features, differential diagnosis and prognosis of primary histiocytic sarcoma of central nervous system(CNS). Methods: Three cases of CNS histiocytic sarcoma were collected at Chinese People′s Liberation Army General Hospital from 2005 to 2018. Their clinicopathological characteristics were analyzed, and the related literature reviewed. Results: The three patients included two females and one male, aged 36, 44, 58 years (median 44 years). MRI showed heterogeneously enhancing lesions which were considered meningioma, high-grade glioma or metastatic carcinoma. Histopathologically there were moderately pleomorphic, mitotically active tumor cells with a loose arrangement, effacing the normal brain tissue. These cells possess abundant eosinophilic cytoplasm, highly atypical nuclei, predominant nucleoli, and hemophagocytosis; multinucleated or spindled forms were also seen, as was background reactive inflammation. The tumor cells were typically positive for CD68, CD163, vimentin and lysozyme, S-100 protein, two of three cases were positive for BRAF V600E,one of three cases was partly positive for CD45, CD45RO, CD4, CD34, and negative for GFAP, Olig-2, CK, EMA, SSTR2, CD99, CD117, MPO, CD1a, Langerin, CD21, CD23, CD35, CD15, CD30, CD38, and CD138. The index of Ki-67 was 30%-75%. Rich reticular fiber network was seen in all cases; BRAF V600E mutation was present in two cases. Conclusions CNS histiocytic sarcoma is a rare malignant tumor; histopathologic and immunohistochemical examination are necessary for the diagnosis and to exclude other primary CNS and hematolymphopoietic tumors. Primary CNS histiocytic sarcoma is treated by surgery, chemotherapy and radiation therapy, but the prognosis is poor. Complete resection combined with high dose focused radiotherapy can improve the prognosis.
