ObjectiveTo investigate the epidemiological characteristics of respiratory adenovirus (AdV) infection among hospitalized patients under 18 years of age with pneumonia in Yancheng City of Jiangsu Province from 2023 to 2024, and to provide a basis for the prevention and control of adenovirus infection. MethodsNasopharyngeal swab samples were collected from hospitalized patients under 18 years of age diagnosed with pneumonia at two national influenza sentinel hospitals in Yancheng City from February 2023 to June 2024. A respiratory pathogen nucleic acid detection kit was used to test for 28 pathogens, including influenza A virus, influenza B virus, respiratory syncytial virus, human rhinovirus, adenovirus, Mycoplasma pneumoniae, Chlamydia pneumoniae, human metapneumovirus, human bocavirus, enterovirus, polyomavirus K1, polyomavirus WU, parainfluenza viruses 1‒4, coronavirus 229E, HKU1, OC43, and NL63, Haemophilus influenzae, Bordetella pertussis, Group A Streptococcus, Staphylococcus aureus, Streptococcus pneumoniae, Legionella pneumophila, Klebsiella pneumoniae, and the novel coronavirus, and to analyze patients’ mixed infections. Adenovirus-positive samples were subjected to polymerase chain reaction (PCR) amplification using Hexon and Fibre as target genes, and the products were analyzed by sequencing. Whole-genome sequencing analyses were performed on positive samples with Ct values less than 22. ResultsAmong 368 hospitalized pneumonia patients under 18 years of age in Yancheng City from February 2023 to July 2024, most were male (51.63%, 190/368), with preschool-aged children (42.66%, 157/368) and primary school-aged children (40.22%, 148/368) comprising the majority. A total of 44 cases tested positive for adenovirus, yielding a positivity rate of 11.96%. Single infections, dual infections, and multiple infections accounted for 61.36% (27/44), 36.36% (16/44), and 2.27% (1/44), respectively. From November 2023, the adenovirus positivity rate rose sharply, peaking at 51.61% in December. Following PCR amplification and sequencing, valid sequences were successfully obtained for 37 strains, comprising 36 AdV-3 strains and 1 AdV-C strain. Eight adenovirus-positive samples with Ct values below 22 were inoculated into HEp-2 cell lines for virus isolation, and whole-genome sequencing analyses were performed on the five successfully isolated strains. Phylogenetic analyses revealed that the AdV-3 strains collectively belonged to the same evolutionary clade. Whole-genome sequencing results indicated that four AdV-3 strains (HAdV-B3) showed no evidence of genetic recombination, whereas one AdV-C strain (HAdV-89) might have undergone genetic recombination. ConclusionThe adenovirus positivity rate among hospitalized pneumonia patients aged under 18 years of age in Yancheng from 2023 to 2024 was slightly higher than that reported in previous studies. Adenovirus infection exhibited a pattern of high incidence in winter, with the AdV-3 type being the predominant pathogen; one AdV-C strain (HAdV-89) might have undergone genetic recombination. It is recommended to strengthen surveillance of respiratory adenovirus type AdV-3 and its variants during the winter season, promote the use of multiplex pathogen detection techniques, and explore the clinical application of an AdV-3 vaccine.

Objective To explore the effects of sacral neuromodulation (SNM) on urodynamic parameters during the storage phase in patients with neurogenic bladder (NB), so as to provide reference for evaluating the efficacy of SNM. Methods A total 49 NB patients undergoing SNM at our hospital during Oct.2012 and May 2025 were enrolled. Baseline data and video-urodynamic parameters were collected. Changes in maximum cystometric capacity, maximum detrusor pressure during storage phase, and bladder compliance before and after treatment were assessed. Improvements in detrusor overactivity (DO) and vesicoureteral reflux (VUR) were also analyzed. Results Among the 49 patients,27 were male and 22 were female, with a mean age of (37.41±15.15) years, a median disease duration of 5.0 (2.0,15.5) years, and a median follow-up of 11 (1,32) months. Up to 37 patients (75.5%) received permanent sacral nerve pulse generator implantation (permanent implant group), while the remaining 12 were classified as the non-permanent implant group. Before and after the test period, all patients showed a significant increase in maximum cystometric capacity [ (218.0 (93.0,358.5) mL vs.300.0 (238.5, 400.0) mL, P<0.001], a decrease in maximum detrusor pressure during the filling phase [32.0 (13.5,71.0) cmH_2 O vs. 20.0 (9.0,50.0) cmH_2 O, P<0.001], and an improvement in bladder compliance [11.8 (8.3,25.6) mL/cmH_2 O vs.26.7 (8.6,44.1) mL/cmH_2O, P<0.001]. In the permanent implant group, comparisons before and after the test period showed an increase in maximum bladder capacity [ (239.16±147.23) mL vs. (312.24±121.83) mL, P<0.001], a decrease in maximum detrusor pressure during filling[32.0 (15.0,58.0) cmH_2 O vs.15.0 (9.0,41.0) cmH_2 O, P<0.05], and improved bladder compliance [10.8 (8.3,23.6) mL/cmH_2 O vs.28.6 (8.6,41.4) mL/cmH_2 O, P<0.001]. No statistically significant differences in these parameters before and after the test period were observed in the non-permanent implant group (P>0.05). A total of 17 patients in the permanent implant group underwent follow-up video urodynamics. Compared to pre-test values, significant improvements were observed in maximum detrusor pressure during filling, and bladder compliance both at the end of the test period and at the last follow-up (P<0.05). However, no statistically significant differences were found in maximum cystometric capacity, maximum detrusor pressure during filling, and bladder compliance between the end of the test period and the last follow-up (P>0.05). Among the 49 patients,21 had DO and 20 had VUR. Both DO and VUR showed improvement after the test period and at the last follow-up. Conclusion SNM can effectively improve storage function in NB patients, ameliorate detrusor overactivity and bladder compliance, and relieve or eliminate VUR in some patients. Long-term follow-up confirms that SNM provides stable therapeutic effects, demonstrating significant clinical value.

Objective To investigate the clinical efficacy of Tongfu Xiefei Formula in treating patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)based on the theory of simultaneous treatment of lung and intestine,and to observe its effects on serum inflammatory cytokines.Methods A retrospective study was conducted on 134 AECOPD patients treated at the Department of Pulmonary Diseases of Traditional Chinese Medicine,Tangshan Hospital of Traditional Chinese Medicine from December 2020 to December 2022.The patients were divided into an observation group and a western medicine group based on the treatment plans,with 67 cases in each group.The western medicine group received conventional western medical treatment,while the observation group was given Tongfu Xiefei Formula orally in addition to the western medical treatment.The course of treatment covered 2 weeks.Before and after treatment,the two groups were observed in the changes of the modified Medical Research Council(mMRC)dyspnea scale scores,COPD Assessment Test(CAT)scores,lung function indicators,arterial blood gas analysis indicators,and serum inflammatory cytokine levels.The clinical efficacy,total incidence of adverse reactions,and hospitalization time were compared between the two groups.Results(1)After 2 weeks of treatment,the total effective rate in the observation group was 95.52%(64/67),compared to 79.10%(53/67)in the western medicine group.The intergroup comparison(tested by the chi-square test)showed that the efficacy of the observation group was significantly superior to that of the western medicine group(P＜0.01).(2)After treatment,the mMRC scores and CAT scores in both groups were significantly decreased(P＜0.05),and the decrease in the observation group was significantly superior to that in the western medicine group(P＜0.01).(3)After treatment,lung function indicators of the forced expiratory volume in one second(FEV1),forced vital capacity(FVC),and their ratio(FEV1/FVC)in both groups were significantly increased(P＜0.05),and the increase in the observation group was significantly superior to that in the western medicine group(P＜0.01).(4)After treatment,the oxygen saturation(SaO2)and arterial oxygen partial pressure(PaO2)levels in both groups significantly increased(P＜0.05),while the arterial carbon dioxide partial pressure(PaCO2)level was significantly decreased(P＜0.05).The increase in SaO2 and PaO2 levels and the decrease in PaCO2 level in the observation group were significantly superior to those in the western medicine group(P＜0.01).(5)After treatment,the levels of serum inflammatory cytokines of tumor necrosis factor α(TNF-α),C-reactive protein(CRP),and interleukin-6(IL-6)in both groups were significantly decreased(P＜0.05),and the decrease in the observation group was significantly superior to that in the western medicine group(P＜0.01).(6)The total incidence of adverse reactions in the observation group was 2.99%(2/67),compared to 5.97%(4/67)in the western medicine group,with no statistically significant difference between the two groups(P＞0.05).(7)The observation group had a significantly shorter hospitalization time than the western medicine group,and the difference was statistically significant(P＜0.05).Conclusion Tongfu Xiefei Formula,formulated based on theory of simultaneous treatment of lung and intestine,is effective and safe on relieving symptoms such as dyspnea in AECOPD patients,improving lung function,correcting arterial blood gas disorders,inhibiting the release of inflammatory factors,shortening treatment time,while causing no serious adverse reactions.

Objective: To analyze the phylogenetic characteristics of VP1 gene of Coxsackievirus A10 (CVA10) isolates from 2004 to 2023, and to understand the genetic evolution and epidemic trends of CVA10, so as to provide references for the prevention and control of hand, foot, and mouth disease. Methods: The full-length sequences of the VP1 region of CVA10 isolates were retrieved from the BV-BRC database before December 15, 2024. Gene typing, sequence analysis, evolutionary analysis, and amino acid mutation site analysis were conducted using bioinformatics software. Results: A total of 1 253 CVA10 isolates VP1 region nucleotide full-length sequences from 2004 to 2023 were included, with 9 strains from 2004 to 2008, 338 strains from 2009 to 2012, and 906 strains from 2013 to 2023. China had the highest number of CVA10 isolates, with 1 143 strains accounting for 91.22%, and the predominant genotype was C3. Compared to the prototype strain, the nucleotide sequence homology of the VP1 region of CVA10 isolates ranged from 74.94% to 77.63%, while the amino acid sequence homology ranged from 88.59% to 93.62%. The third codon position preferred cytosine and thymine. The top three most abundant amino acids were threonine, alanine, and valine. The average relative synonymous codon usage of 30 amino acid codon groups was greater than 1. The average amino acid substitution entropy value was 0.04, with four amino acid mutation-prone sites identified, and the mutation-prone rate was 1.35%. Conclusions From 2004 to 2023, the majority of CVA10 isolates were primarily sourced from China, with genotype C3 being the predominant circulating strain in China. The nucleotide homology between the CVA10 isolates and the prototype strain was relatively low, and mutation-prone sites were identified, indicating that enhanced monitoring of viral variation is necessary.

Objective To compare the technical indicators and clinical effect of catheter-directed thrombolysis(CDT)via two types of non-popliteal venous access in the treatment of acute mixed-type lower extremity deep vein thrombosis(DVT).Methods The clinical data of 119 patients with acute mixed-type lower extremity DVT,who were admitted to the Affiliated Jiangning Hospital of Nanjing Medical University and the Affiliated Nanjing Hospital of Nanjing Medical University of China to receive CDT treatment from January 2016 to June 2022,were retrospectively analyzed.Of the 119 patients,CDT via deep calf vein access was carries out in 45(calf vein group)and CDT via healthy-side femoral venous access was performed in 74(femoral vein group).The success rate of vascular puncture,success rate of catheterization technique,number of successful CDT venous puncturing,time spent for sheath placement,time spent for catheterization,thrombolysis time,used amount of thrombolytic agent and associated complications(including vein puncturing and anticoagulant thrombolysis-related complications),the thrombolytic effect of different anatomical segments,and the clinical efficacy during the follow-up period for at least 12 months were compared between the two groups.Results Successful catheterization via deep calf vein access and via healthy-side femoral vein access was obtained in 31 and 58 CDT patients respectively,with a technical success rate of 68.89％(31/45)and 78.38％(58/74)respectively,the difference between the two groups was not statistically significant(P=0.248).In 26 patients(67.74％)of the calf vein group,more than two times of puncturing were needed before the sheath placement could be successfully achieved.The time spent for sheath placement in the femoral vein group was(1.84±0.87)min,which was remarkably shorter than(10.52+6.13)min in the calf vein group(P＜0.001),but the time spent for catheterization in the femoral vein group was(41.60±13.31)min,which was obviously longer than(20.06+4.46)min in the calf vein group(P＜0.001).The thrombolysis time in the femoral vein group and the calf vein group was(5.34+1.43)days and(5.06±1.18)days respectively(P=0.354),and the used amount of thrombolytic agent in the femoral vein group was(352.16±71.98)×104 U,which was prominently larger than(284.68±77.64)× 104 U in the calf vein group(P＜0.001).The last follow-up check showed that the patency rate of the popliteal vein in the calf vein group was significantly higher than that in the femoral vein group(P=0.037).No statistically significant differences in the incidence of post-thrombotic syndrome(PTS)and the mean VEINES-QOL/Sym scores existed between the two groups(all P＞0.05).Conclusion Compared with CDT via healthy-side femoral vein access,CDT via deep calf vein access can better remove the thrombus in the popliteal vein and superficial femoral vein,and improve the femoropopliteal vein patency rate,although it has no obvious advantages in reducing the occurrence of PTS and in improving the VEINES-QOL/Sym score,moreover,the deep calf vein puncture and sheath placement require a high-level technique.

Objective To investigate the early clinical efficacy of minimally invasive cardiac surgery coronary artery bypass grafting (MICS CABG) via left intercostal small incision for multivessel coronary artery disease. Methods The patients who received off-pump CABG in the Central China Fuwai Hospital of Zhengzhou University from June 2021 to June 2023 were enrolled. Patients were divided into two groups according to the operative technique used, including a traditional midline sternotomy group and a left intercostal small incision group. The clinical data of the two groups were compared. Results A total of 143 patients were enrolled, including 70 patients in the traditional midline sternotomy group and 73 patients in the left intercostal small incision group. The age of the patients in the left intercostal small incision group and the traditional midline sternotomy group was (63.8±8.0) years and (63.0±7.8) years, respectively; the proportions of males were 69.9% and 74.3%, respectively. The differences were not statistically significant (all P>0.05). All patients in the two groups successfully completed the operation, and no patients in the left intercostal small incision group were converted to thoracotomy. The patients in the left intercostal small incision group showed less postoperative drainage within postoperative 24 hours [(239.4±177.7) mL vs. (338.0±151.9) mL, P<0.001], lower perioperative blood transfusion rate [32.9% (24/73) vs. 51.4% (36/70), P=0.028], higher postoperative myoglobin level within postoperative 24 hours [366.1 (247.9, 513.0) ng/mL vs. 220.8 (147.2, 314.9) ng/mL, P<0.001], shorter intensive care unit stay [45.5 (31.5, 67.5) h vs. 68.0 (46.0, 78.5) h, P=0.001] and postoperative hospital stay [(10.8±4.0) d vs. (13.1±5.3) d, P=0.028] compared to the traditional midline sternotomy group. There was no significant difference in the incidence of major adverse cardiac and cerebrovascular event between the two groups [2.7% (2/73) vs. 2.9% (2/70), P=1.000]. Conclusion Compared to the full median sternotomy, MICS CABG leads to a good clinical result with smaller trauma, faster overall recovery, and less perioperative blood transfusion.

Objective:To compare the clinical efficacy of catheter-directed thrombolysis (CDT) via the contralateral femoral vein approach (CFVA-CDT) and the calf deep vein approach (CVA-CDT) in the treatment of acute mixed-type lower extremity deep vein thrombosis (DVT).Methods:Patients treated with CFVA-CDT and CVA-CDT for acute mixed-type DVT were retrospectively collected from January 2018 to December 2021, totaling 49 and 32 patients, respectively. The relevant technical indicators, thrombolysis rates in the iliac-femoral vein segment and femoral-popliteal vein segment, clinical efficacy, and the incidence of lower extremity deep vein patency, venous valve insufficiency, and post-thrombotic syndrome (PTS), as well as the severity of chronic venous disease in the affected limb (VCSS score) during a 2-year follow-up period were retrospectively compared between the two venous access CDT groups. The t-test was used for comparing quantitative data, while the chi-square test or Fisher′s exact test was used for categorical data.Results:During CFVA-CDT procedure, 6-8 F vascular sheaths were used, and balloon dilation of 2~6 mm was more frequently employed (65.31%, 32/49) to expand venous stenosis/occlusion segments before successful sheath placement compared to the CVA-CDT group (37.50%, 12/32), and the difference was statistically significant ( P=0.014). In the CVA-CDT group, 31.25% (10/32) of patients had a maximum sheath size of 6 F, while the remainder used 4 or 5 F sheaths. Among them, 34.38% (11/32) of patients required re-puncture of the popliteal or femoral vein for larger sheaths (≥8 F) for thrombus aspiration and subsequent endovascular treatment during or after thrombolysis. The effective thrombolysis rates (≥50%) in the iliac-femoral vein segment were not significantly different between the two groups ( P=0.778). The effective thrombolysis rate of the femoral-popliteal venous segment is related to the presence or absence of popliteal vein opacification on lower extremity venous antegrade venography. There was no significant difference between the groups when the popliteal vein was visualized ( P=1.000). While the popliteal vein was not visualized, the CVA-CDT group (75.0%, 15/20) was significantly better than the CFVA-CDT group (34.38%, 11/32), and the difference was statistically significant ( P=0.004). There was no significant difference in clinical efficacy between the two groups ( P=0.819). During follow-up, the femoral-popliteal vein patency rate in the CVA-CDT group (87.50%, 28/32) was significantly higher than in the CFVA-CDT group (44.90%, 22/49), the difference was statistically significant ( P<0.001). Conclusions:Successful CFVA-CDT requires the assistance of more ancillary devices, while the use of larger sheaths is more limited in CVA-CDT due to the smaller caliber of the calf deep veins. The presence or absence of popliteal vein opacification on lower extremity venous antegrade venography may influence the effective thrombolysis of the femoral-popliteal venous segment thrombus in patients with acute mixed deep vein thrombosis (DVT) treated with CFVA-CDT and CVA-CDT. Compared to CFVA-CDT, CVA-CDT can improve the patency rate of the femoral-popliteal venous segment.

Syndactyly is a deformity that the soft tissues and (or) bones of two or more fingers are joined together. Based on the severity of interphalangeal skin-soft tissue juxtaposition, syndactyly is categorized as: incomplete syndactyly and complete syndactyly. Complete syndactyly correction includes interphalangeal separation, web-space reconstruction, coverage of skin defects on the body of the finger, and fingertip formation. The key step is the formation of the lateral nail fold after the separation of the syndactyly, and the shaping technique is closely related to the postoperative appearance of the fingertip. By reviewing the literatures, this article presents an overview of the relevant anatomy, nail juxtaposition typing, and the principles and applications of the complete juxtaposition nail lateral nail fold molding procedure.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To investigate the clinicopathological characteristics, immunophenotypes, diagnostic criteria and differential diagnosis of atrophic kidney-like lesion (AKLL).Methods:Three cases of AKLL were collected from April 2021 to October 2023 at the Xiangya Hospital of Central South University, Changsha, Zhejiang Provincial People′s Hospital, Hangzhou and Ningbo Clinical Pathology Diagnosis Center, Ningbo, China. The clinical, morphological, and immunohistochemical characteristics were analyzed. Relevant literature was also reviewed. A targeted DNA-based next-generation sequencing (a panel of 150 genes) was performed on one of the three cases.Results:There were 1 female and 2 males, aged 30, 57, and 17 years (mean 34.6 years), respectively. The lesions were all incidentally identified during physical or imaging examination. Radiologically, they were all presented as a unilateral renal parenchymal mass. Grossly, the maximum diameters of the lesions were 1.8, 4.0, and 6.5 cm (mean 4.1 cm), respectively. The tumor cut-surfaces were sponge-like, multilocular cystic, and solid, respectively. At low magnification, the lesions were well-circumscribed, while a thick fibromuscular capsule was noted in cases 1 and 3. Cases 1 and 2 were composed of thin-walled cysts or follicular like structures of varying sizes, with the cyst wall lined by flattened and atrophic, or hobnail cells. The luminal spaces contained dense eosinophilic secretion and associated calcifications, while some cysts contained discohesive cells floating in the eosinophilic material. The tissue between the cysts showed predominantly small atrophic tubular structures. Case 3 was almost entirely composed of atrophic and collapsed tubular structures with focal cyst formation, imparting a solid sheets growth pattern under low magnification. Immunohistochemical staining revealed that the cyst lining cells and the intracystic floating cells were WT1 positive, PAX8 negative and CK7 negative, while the atrophic renal tubules were WT negative, PAX8 positive and CK7 positive. Targeted next-generation sequencing in case 1 showed no significant genetic abnormalities. All 3 patients underwent partial nephrectomy. No evidence of recurrence or metastasis was found with a follow-up of 17 to 36 months.Conclusions:AKLL is a rare and novel benign renal disease. It is easily misdiagnosed as a renal neoplasm grossly and histologically. Careful morphological observation combined with characteristic immunophenotypes can aid in its diagnosis and differential diagnosis.
