Objective:To investigate the clinical characteristics of omphalocele, and to assess the risk factors associated with adverse outcomes.Methods:A retrospective cohort study was conducted. Clinical data of 224 patients diagnosed with omphalocele, who were hospitalized at Children′s Hospital, Zhejiang University School of Medicine from January 2013 to December 2022, were collected. Based on their discharge outcomes, the patients were classified into 2 groups: favorable outcomes and unfavorable outcomes. Chi-square test or continuity correction χ2 test or Fisher exact probability method, and Mann-Whitney U test were used for intergroup comparisons. Logistic regression analysis was performed to identify risk factors associated with adverse outcomes in omphalocele. Results:Among the 224 patients with omphalocele, 126 were male. A total of 208 patients (92.9%) had favorable outcomes, while 16 patients (7.1%) had unfavorable outcomes. In the unfavorable outcomes group, 14 patients had giant omphaloceles, while 100 patients had giant omphaloceles in the favorable outcomes group. The rates of herniation of more than two intra-abdominal organs in the hernial sac, congenital heart defects, patent ductus arteriosus, pulmonary hypertension, sepsis and infection of the hernial sac, were all higher in the unfavorable outcomes group compared to the favorable outcomes group (all P<0.05). Patients with unfavorable outcomes had longer mechanical ventilation time, duration of oxygen use, duration of parenteral nutrition, hospital stays, and higher rates of parenteral nutrition-associated cholestasis compared to those with favorable outcomes (all P<0.01). Multivariate Logistic regression analysis indicated that pulmonary hypertension ( OR=9.39, 95% CI 1.20-73.32), sepsis ( OR=8.59, 95% CI 1.32-55.86), and congenital heart defects ( OR=6.55, 95% CI 1.11-38.73) were all independent risk factors for adverse outcomes in omphalocele (all P<0.05). Conclusions:Infants with omphalocele are prone to complications such as cardiovascular malformations, infections, and pulmonary hypertension. Adverse outcomes in omphalocele are associated with pulmonary hypertension, sepsis, and congenital heart defects.

Patient-Reported Outcomes(PRO)is a subjective outcome indicator based on the concept of"patient-centered",in which patients report their own information such as health status,functional status,and treatment feelings,which is an ef-fective supplement to traditional objective outcome indicators.Based on the development status of the Patient Reported Outcome Measure(PROM),it systematically analyzed the concepts related to PRO with the goal of clarifying the Patient Experience Data(PED)with research value,and proposed six core types of PROs in the medical field,including health-related quality of life,health preference,health behavior,symptom burden,functional status and patient-reported experience.For each type of PRO,the key characteristics of the study were analyzed,the evidence and application directions of related PED and the production based on PED were described,and the existing international mainstream PROMs were reviewed.It is hoped that the connotation of PRO-related concepts can be comprehensively expounded,and PEDs with research significance and value can be explored,so as to provide guidance for the focus of PRO-related research in China,so as to promote the application and development of PRO in China.

Objective To investigate the CT and MRI features of intraosseous myofibroma/myofibromatosis in pediatric patients.Methods The retrospective analysis involved the examination of clinical data and imaging findings from 15 children who were diagnosed with myofibroma/myofibromatosis of bone invasion through pathological means.Subsequently,the imaging characteristics were summarized.Results CT examinations were conducted on a total of 15 patients,with 2 of them also received enhanced scans.Additionally,MRI examinations were conducted on 5 patients,with 3 of them also underwent enhanced scans.Eleven patients were diagnosed with solitary type myofibroma,with 7 cases localized in the skull and the remaining lesions observed in the maxillofacial bone.Three patients exhibited the multicentric type without any involvement of visceral organs,while one patient presented with the multicentric type accompanied by visceral involvement.The lesions exhibited a uniform soft-tissue density on plain CT scan,predominantly located between the inner and outer layers of the bone.Additionally,they displayed swelling changes and osteolytic bone destruction,with some lesions showed residual bone shell.On MRI,the lesions exhibited a uniform signal,demonstrated an isointense or slightly hypointense signal on T1WI and an isointense or slightly hyperintense signal on T2WI.The lesions displayed significantly heterogeneous enhancement on CT and MRI.Conclusion The imaging manifestations of intraosseous myofibroma/myofibromatosis in pediatric patients exhibit certain characteristics,and the residual bone shell in the lesion is helpful for diagnosis,however,distinguishing it from Langerhans cell histiocytosis of the bone remains challenging,necessitating the reliance on pathological diagnosis.

Objective:To analyze the epidemiological characteristics of human respiratory syncytial virus (HRSV) in patients with acute respiratory infection (ARIs) in sentinel hospitals of the Hubei influenza surveillance network from 2016 to 2023.Methods:ARIs samples [including influenza-like cases (ILI) and severe acute respiratory infection (SARI)] were collected from influenza surveillance sentinel hospitals in Hubei Province from 2016 to 2023, and case information was collected. HRSV virus nucleic acid typing was performed by fluorescence quantitative PCR method, and the data were collated, plotted and analyzed.Results:From 2016 to 2023, 12 779 cases of ILI and 9 166 cases of SARI were collected. The positive rate of HRSV was the highest in<5 years of age group [15.77% (168/1 065)], among which the positive rate was the highest in 2 to 5 years of age group of ILI cases [13.60% (31/228)], and the positive rate was the highest in 0 to 2 years of age group of SARI cases [25.97% (60/231)] (all P values<0.001). The positive rate of HRSV in SARI cases was 2.31%-25.97%, higher than that in ILI cases (0-13.60%) ( P=0.016). HRSV was prevalent in autumn and winter from 2016 to 2020 and in spring in 2023. Alternating epidemics of HRSV virus type A and B in Hubei Province from 2016 to 2023 (dominant epidemics of type B in 2016 and 2020; dominant epidemics of type A in 2017-2019 and 2023). Conclusion:SARI and ILI patients under five years old are the main infection groups of HRSV. The seasonal prevalence characteristics of HRSV in Hubei Province from 2016 to 2023 shift from autumn and winter to spring.

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease with a complex pathogenesis, which causes the lack of precise and personalized prevention, control, and treatment approaches in clinical practice. Traditional Chinese medicine (TCM) with multiple components acting on multiple targets plays a role in the prevention and treatment of COPD. After evaluating the treatment of cough, dyspnea, and lung distension based on syndrome differentiation in TCM, we summarized the commonly used TCM preparations for treating COPD. These preparations are mainly composed of medicines for clearing interior heat and releasing exterior, tonifying, activating blood and resolving stasis, resolving phlegm, relieving cough and breathlessness, and regulating Qi movement. Because all of them contain a variety of active ingredients such as flavonoids, terpenoids, and phenols, we analyzed the mechanisms of the classic prescriptions alone or in combination with othermedicines or therapeuticmethods. These mechanisms involve counteracting inflammation, oxidative stress, and fibrosis, inhibiting apoptosis, alleviating airway remodeling, and enhancing immunity. Meantime, we summarized the existing problems in the treatment of COPD by TCM. This review provides a scientific basis for the research and treatment of COPD in the future.

ObjectiveTo study the effect of Tanreqing injection （TRQ） on the pulmonary flora in the rat model of chronic obstructive pulmonary disease （COPD）. MethodWistar rats were randomized into control， model， and TRQ groups. The rats in other groups except the control group were treated by smoking combined with intratracheal instillation of lipopolysaccharide for the modeling of COPD. The TRQ group was intraperitoneally injected with TRQ （2 g·kg^-1）. At the end of the experiment， after blood collection from the abdominal aorta of the rats， the lung tissue was collected for hematoxylin-eosin and picric sirius red staining to reveal the pathological changes. The lung lavage fluid was collected， and the diversity and relative abundance of lung flora in different groups were analyzed by 16S rDNA amplicon sequencing. ResultThe lungs of the control group were normal， and those of the model group showed neutrophil infiltration， telangiectasia， lung hemorrhage and emphysema in individual cases， and thickening of collagen fibers in the trachea. Compared with the model group， the TRQ group showed significantly improved lungs and recovered collagen fibers. The MLI analysis showed that compared with the control group， the model group showcased increased alveolar space （P<0.01）， which was reduced in the TRQ group （P<0.05）. Compared with the control group， the model group showed increased wall thickness （P<0.01）， and the increase was attenuated in the TRQ group （P<0.01）. TRQ increased the Simpson index and altered the α diversity of pulmonary flora. The results of principal co-ordinate analysis showed that TRQ changed the β diversity and reduced the β diversity index of pulmonary flora. At the genus level， the model group showed increased relative abundance of g_Bacillus and g_Brevundimonas and decreased relative abundance of g_Pseudomonas， compared with the control group. After treatment with TRQ， the relative abundance of g_Stenotrophomonas increased， and that of g_Bacillus decreased. The LEfSe of differential taxa between groups showed that the modeling increased the relative abundance of g_Lachnospiraceae_NK4A136_group， and TRQ treatment increased the relative abundance of g_Rhodococcus and g_Stenotrophomonas. ConclusionTRQ can regulate the diversity of pulmonary flora and restore the balance of bacterial genera in the rat model of COPD， which may be one of the mechanisms of the prevention and treatment of COPD with TRQ.
