Objective:To investigate the risk factors and ultrasonographic features of neonatal hepatic subcapsular haematoma (HSH).Methods:A retrospective study was conducted on five neonates diagnosed with HSH at Shaoxing Maternity and Child Health Care Hospital from June 2020 to June 2024. Clinical data, including clinical manifestations, ultrasonographic characteristics, and follow-up outcomes, and the risk factors of HSH were summarized with descriptive statistical analysis.Results:All five cases were very low/extremely low birth weight preterm infants delivered by cesarean section, with a history of birth asphyxia. Case 1 presented with hypovolemic shock postnatally and was incidentally diagnosed with HSH via abdominal ultrasound. Cases 2 and 3 were diagnosed during a routine ultrasound monitoring of the umbilical venous catheter tip position within 3 d after catheterization. Cases 4 and 5 were diagnosed by abdominal ultrasound re-examination following unsuccessful umbilical venous catheterization. Case 1 received no catheterization or external chest compression, while Cases 2, 3, and 5 received external chest compression during resuscitation. Case 2 had a history of difficult cesarean section. Cases 2 to 5 underwent umbilical venous catheterization (failed in Cases 4 and 5). Ultrasonography revealed cystic-dominant echogenicity, presenting as elongated or oval-shaped with well-defined margins, and were accompanied by varying amounts of echogenic bands and dots. Three cases had single lesions and two had multiple lesions. A total of nine hemorrhagic foci were found with four in the right posterior liver lobe, three in the right anterior lobe, and two in the left lobe. No hepatic capsule disruption was observed in any of the five cases. After immobilization, hemostasis, and supportive care, the haematoma in Case 1 completely resolved with calcification at 134 d after birth, while in the remaining four cases, the haematomas resolved completely without calcification between 17 and 62 d after birth.Conclusions:HSH may present without classical symptoms or signs. In neonates with very low/extremely low birth weight presenting hypovolemic shock, HSH should be suspected, particularly in those with perinatal trauma or a history of external chest compression during resuscitation. Abdominal ultrasound is recommended for exclusion if indicated. Ultrasound not only facilitates the diagnosis of HSH, but also enables dynamic monitoring of hematoma progression and resolution.

BACKGROUND: Lung cancer is currently the most prevalent malignancy and the leading cause of cancer deaths worldwide. Although the early stage non-small cell lung cancer (NSCLC) presents a relatively good prognosis, a considerable number of lung cancer cases are still detected and diagnosed at locally advanced or late stages. Surgical treatment combined with perioperative multimodality treatment is the mainstay of treatment for locally advanced NSCLC and has been shown to improve patient survival. Following the standard methods of neoadjuvant therapy, perioperative management, postoperative adjuvant therapy, and other therapeutic strategies are important for improving patients' prognosis and quality of life. However, controversies remain over the perioperative management of NSCLC and presently consensus and standardized guidelines are lacking for addressing critical clinical issues in multimodality treatment. METHODS: The working group consisted of 125 multidisciplinary experts from thoracic surgery, medical oncology, radiotherapy, epidemiology, and psychology. This guideline was developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The clinical questions were collected and selected based on preliminary open-ended questionnaires and subsequent discussions during the Guideline Working Group meetings. PubMed, Web of Science, Cochrane Library, Scopus, and China National Knowledge Infrastructure (CNKI) were searched for available evidence. The GRADE system was used to evaluate the quality of evidence and grade the strengths of recommendations. Finally, the recommendations were developed through a structured consensus-building process. RESULTS: The Guideline Development Group initially collected a total of 62 important clinical questions. After a series of consensus-building conferences, 24 clinical questions were identified and corresponding recommendations were ultimately developed, focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assement, and follow-up protocols for NSCLC. CONCLUSIONS This guideline puts forward reasonable recommendations focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assessment, and follow-up protocol of NSCLC. It standardizes perioperative multimodality treatment and provides guidance for clinical practice among thoracic surgeons, medical oncologists, and radiotherapists, aiming to reduce postoperative recurrence, improve patient survival, accelerate recovery, and minimize postoperative complications such as atelectasis.

Objective:To estimate the burden of influenza-associated outpatient consultations in China from 2011 to 2021 surveillance years to provide a reference for developing influenza prevention, control strategies, and vaccination policies.Methods:Data on influenza-like illness (ILI) and virological confirmation of sentinel specimens from 2011 to 2021 surveillance years were extracted from China's national sentinel surveillance system. Generalized additive models were fitted to estimate influenza-associated excess ILI outpatient burden, accounting for seasonal baselines and meteorological factors.Results:Influenza was associated with an average of 1.66 (95% CI: 1.51-1.80) excess ILI consultations per 1 000 person-years (py) in China each year from 2011 to 2021 surveillance years. The influenza-associated outpatient burden was similar across different virus types/subtypes. Influenza A(H1N1)pdm09 led to a higher rate of influenza- associated ILI consultations [0.65 (95% CI: 0.53-0.76) per 1 000 py] compared to other types/subtypes. The age groups with the highest burdens were children aged 0-4 years and 5-14 years, with excess outpatient consultation rates of 15.23 (95% CI: 13.73-16.73) per 1 000 py and 13.53 (95% CI: 12.49-14.52) per 1 000 py, respectively. Conclusions:Influenza caused many outpatient consultations in China, particularly among children aged 0-14. Continuous influenza monitoring and disease burden assessment should be conducted, and close attention should be paid to the changing trends of various influenza virus types/subtypes. When formulating vaccination strategies, priority should be given to recommending vaccination for high-risk populations, such as children.

Objective To observe the effect of sevoflurane(SEV)on the expression of myocardial biological clock gene aromatic hydrocarbon receptor nuclear transport-like protein 1(BMAL1)in diabetic rats and to explore its changes.Methods Sixty healthy male SD rats with a body mass of 200-250 g were divided into oxygen inhalation group(NC)and sevoflurane inhalation group(SEV).The diabetic model was routinely replicated,and the model was divided into oxygen group(DM)and sevoflurane group(DM+SEV)with an inhalation time of 5 h(n=15).Four groups of experimental animals were executed at 0,12 and 24 h after the anesthesia was stopped and then myocardial tissue was isolated.Western blot was used to determine the expression level of biological clock gene BMAL1 protein and its activation enzyme USP9X;HE staining microspy to observe the pathological changes of my-ocardial tissue and immuno-fluorescence co-localization to observe the relationship between USP9X and BMAL1.Results At 0 and 12 h after stopping anesthesia,the expression of BMAL1 and USP9X in the DM+SEV group was significantly down-regulated as compared with the DM group,and the expression of BMAL1 and USP9X in the DM+SEV group was significantly down-regulated(P<0.05)at 24 h after stopping anesthesia(P>0.05).HE staining microscopy found changes of myocardial tissue structure in the DM+SEV group at 0 and 12 hrs after stopping anes-thesia.This change was most significant at 0 h after stopping anesthesia,but the myocardial tissue structure was neatly arranged at 24 h.The results of immuno-fluorescence colocalization showed that USP9X and BMAL1 proteins were mainly distributed in the cytoplasm of cardio-myocardium with and overlapping parts between them.Under the influence of sevoflurane,there was less overlap between the two at 0 and 12 hrs after stopping anesthesia and more overlap between the two at 24 h,which was close to that of the DM group.Conclusions Sevoflurane reversibly changes the expression of myocardial circadian clock gene BMAL1 in diabetic rats and this change still existe for 12 h after stopping anesthesia,then significantly fade away 24 hrs after stopping anesthesia.

Azvudine and nirmatrelvir/ritonavir (Paxlovid) are recommended for COVID-19 treatment in China, but their safety and efficacy in the elderly population are not fully known. In this multicenter, retrospective, cohort study, we identified 5131 elderly hospitalized COVID-19 patients from 32,864 COVID-19 patients admitted to nine hospitals in Henan Province, China, from December 5, 2022, to January 31, 2023. The primary outcome was all-cause death, and the secondary outcome was composite disease progression. Propensity score matching (PSM) was performed to control for confounding factors, including demographics, vaccination status, comorbidities, and laboratory tests. After 2:1 PSM, 1786 elderly patients receiving azvudine and 893 elderly patients receiving Paxlovid were included. Kaplan-Meier and Cox regression analyses revealed that compared with Paxlovid group, azvudine could significantly reduce the risk of all-cause death (log-rank P = 0.002; HR: 0.71, 95% CI: 0.573-0.883, P = 0.002), but there was no difference in composite disease progression (log-rank P = 0.52; HR: 1.05, 95% CI: 0.877-1.260, P = 0.588). Four sensitivity analyses verified the robustness of above results. Subgroup analysis suggested that a greater benefit of azvudine over Paxlovid was observed in elderly patients with primary malignant tumors (P for interaction = 0.005, HR: 0.32, 95% CI: 0.18-0.57) compared to patients without primary malignant tumors. Safety analysis revealed that azvudine treatment had a lower incidence of adverse events and higher lymphocyte levels than Paxlovid treatment. In conclusion, azvudine treatment is not inferior to Paxlovid treatment in terms of all-cause death, composite disease progression and adverse events in elderly hospitalized COVID-19 patients.

In recent decades, the prevalence of hyperuricemia and gout has increased dramatically due to lifestyle changes. The drugs currently recommended for hyperuricemia are associated with adverse reactions that limit their clinical use. In this study, we report that berberine (BBR) is an effective drug candidate for the treatment of hyperuricemia, with its mechanism potentially involving the modulation of gut microbiota and its metabolite, succinic acid. BBR has demonstrated good therapeutic effects in both acute and chronic animal models of hyperuricemia. In a clinical trial, oral administration of BBR for 6 months reduced blood uric acid levels in 22 participants by modulating the gut microbiota, which led to an increase in the abundance of Bacteroides and a decrease in Clostridium sensu stricto_1. Furthermore, Bacteroides fragilis was transplanted into ICR mice, and the results showed that Bacteroides fragilis exerted a therapeutic effect on uric acid similar to that of BBR. Notably, succinic acid, a metabolite of Bacteroides, significantly reduced uric acid levels. Subsequent cell and animal experiments revealed that the intestinal metabolite, succinic acid, regulated the upstream uric acid synthesis pathway in the liver by inhibiting adenosine monophosphate deaminase 2 (AMPD2), an enzyme responsible for converting adenosine monophosphate (AMP) to inosine monophosphate (IMP). This inhibition resulted in a decrease in IMP levels and an increase in phosphate levels. The reduction in IMP led to a decreased downstream production of hypoxanthine, xanthine, and uric acid. BBR also demonstrated excellent renoprotective effects, improving nephropathy associated with hyperuricemia. In summary, BBR has the potential to be an effective treatment for hyperuricemia through the gut-liver axis.

Objective:To explore the clinical characteristics and genetic etiology for a Chinese pedigree affected with Dyschromatosis symmetrica hereditaria (DSH) in conjunct with developmental delay.Methods:A child who had presented at the First Affiliated Hospital of Zhengzhou University on May 28 2021 for abnormal skin pigmentation of the extremities and growth retardation for over 2 years was selected as the study subject. Clinical data of the child and his pedigree (11 individuals from three generations) was collected. The child was subjected to whole exome sequencing, and candidate variant was verified by Sanger sequencing.Results:The child, a two-year-and-seven-month-old male, had hyper- and hypopigmentation on his hands, feet and face, in addition with delayed development. All members of his pedigree had typical presentation of DSH. A heterozygous c. 2657G>A variant was found in exon 8 of the ADAR gene in the child, his mother, and elder sister. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was predicted as likely pathogenic (PM1+ PM2_Supporting+ PP1+ PP3). Conclusion:The c. 2657G>A variant of the ADAR gene probably underlay the DSH in this pedigree.

Objective:To validate and compare the value of the Status Epilepticus in Pediatric Severity Score (STEPSS) versus PEDSS in assessing the short-term prognosis of children with status epilepticus (SE).Methods:Clinical data of 152 children with SE hospitalized at the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2022 were retrospectively analyzed.According to the STEPSS and PEDSS scores, children with SE were scored and their prognosis was predicted.Receiver operating characteristic (ROC) curves of the 2 scales in assessing the short-term prognosis of SE in children were plotted, and the area under the curve (AUC), optimal cut-off, sensitivity and specificity were calculated, thus validating and comparing the value of the STEPSS versus PEDSS in assessing the short-term prognosis of children with SE.Results:Of the 152 children with SE, 90 were male and 62 were female, with the age of (5.8±3.9) years (1 month to 15 years). There were 112 cases with good prognosis and 40 cases with poor prognosis, involving 13 deaths.The AUC of STEPSS and PEDSS scores in predicting the death in children with SE were 0.908(95% CI: 0.848-0.967) and 0.887(95% CI: 0.831-0.942), respectively, both with the optimal cut-off value of 4.The sensitivity of STEPSS and PEDSS scores in predicting the death in children with SE were 0.740 and 0.846, respectively, and the specificity were 0.745 and 0.835, respectively.There was no significant difference in predicting the death in children with SE between the 2 scales ( P>0.05). In predicting adverse outcomes, the AUC of the STEPSS and PEDSS scores were 0.869(95% CI: 0.800-0.937) and 0.926(95% CI: 0.873-0.979), respectively, both with the optimal cut-off value of 3.The sensitivity of STEPSS and PEDSS scores in predicting adverse outcomes in children with SE were 0.827 and 0.900, respectively, and the specificity were 0.732 and 0.866, respectively.There was significant difference in predicting the adverse outcomes in children with SE between the 2 scales ( P<0.05). Conclusions:Compared with the STEPSS, the PEDSS has a higher application in predicting the short-term treatment outcome of children with SE, which can be used as a routine method to assess the prognosis of children with SE.
