Objective To systematically analyze the disease burden, long-term trends, and age-sex distribution of major valvular heart disease (VHD) subtypes—rheumatic heart disease (RHD), non-rheumatic valvular disease (NRVD), and non-rheumatic calcific aortic valve disease (CAVD)—in global, Chinese, and US populations from 1990 to 2021, providing evidence for public health strategies and clinical resource allocation. Methods Based on publicly available data from the Global Burden of Disease (GBD) Study 2021, we extracted incidence, mortality, and disability-adjusted life years (DALYs) for VHD from 1990 to 2021. Age-standardized rates (ASRs) were calculated using the GBD 2021 global standard population, and the estimated annual percentage change (EAPC) with its 95% uncertainty interval (UI) was computed for the period. Data from the Agency for Healthcare Research and Quality (AHRQ), the European Society of Cardiology (ESC)/Eurostat surveys, and Chinese national registries were used for trend triangulation and contextual background. Results From 1990 to 2021, the ASR and disease burden of RHD significantly decreased globally and in China (EAPC for DALYs in China: −4.8%, 95%UI: −5.0% to −4.6%). In contrast, the burden of NRVD and CAVD steadily increased in aging populations like those in China and the US, with a higher burden observed in older adults and males. In 2021, the incidence of NRVD and CAVD peaked in individuals aged ≥65 years, with rates being significantly higher in men than in women. RHD burden was concentrated in low socio-demographic index (SDI) regions, whereas NRVD/CAVD burden was strongly associated with high-SDI regions. Conclusion The global VHD epidemiological landscape is transitioning from an RHD-dominant to an NRVD/CAVD-dominant pattern. China faces a dual challenge of a residual RHD burden and a rapidly growing burden of degenerative valvular diseases. Developing tailored screening, prevention, and treatment strategies for different disease subtypes and populations is crucial.

Objective To propose a framework for risk assessment and stepwise management of pulmonary nodules based on existing guidelines and key studies, and to clarify the boundaries for triage, workup escalation, and referral in different detection scenarios. Methods A problem-oriented evidence synthesis approach was used, prioritizing Chinese expert consensus, Fleischner Society Guidelines, British Thoracic Society (BTS) Guidelines, and Lung-RADS. This was supplemented by studies on risk models, imaging measurements, liquid biopsy, tissue sampling, and surgical treatments. This paper is not presented as a formal consensus or a validated clinical pathway. Results A three-tiered framework consisting of basic non-invasive assessment, advanced assessment, and invasive diagnosis was established. It specified the applicable populations, boundaries for the use of risk models, imaging review, management of conflicting results, evaluation of histopathological consistency, and post-intervention follow-up. Liquid biopsy, genetic testing, and artificial intelligence were defined as investigational or adjunctive tools. Conclusion This framework can serve as a preliminary reference for multidisciplinary teams in developing local protocols. It cannot replace applicable guidelines, pathological diagnosis, shared decision-making with patients, or real-world validation.

Objective:To explore the genetic etiology of Pontocerebellar Hypoplasia Type 2D (PCH2D) due to compound heterozygous variants of the SEPSECS gene and to conduct a literature review. Methods:A child with PCH2D diagnosed at the Children′s Hospital of Nanjing Medical University due to " motor and cognitive retardation" in June 2022 was selected as the study subject. Clinical and imaging data were collected. Genomic DNA was extracted from the peripheral blood samples of the child and her parents. Whole-exome sequencing (WES) was conducted using capture-based high-throughput sequencing technology. Candidate variants were confirmed by Sanger sequencing and bioinformatics analysis. The pathogenicity of variant was rated according to the Standards and Guidelines for the Interpretation of Sequence Variants released by American College of Medical Genetics and Genomics (ACMG). Additionally, relevant literature on PCH2D caused by SEPSECS gene variants was reviewed to assess the genotype-phenotype correlation. This study was approved by the Medical Ethics Committee of the Children′s Hospital of Nanjing Medical University (Ethical No.: 202402022-1). Results:The child, a 1-year-and-3-month-old girl, had presented with global developmental delay, progressive microcephaly, hypotonia, elevated blood lactic acid, feeding difficulties, and absent tendon reflexes. Cranial MRI indicated thinning of the splenium of the corpus callosum. Electromyography suggested peripheral neurogenic changes primarily affecting sensory nerves. WES revealed the she has harbored compound heterozygous variants of the SEPSECS gene, namely c. 194A>G (p.N65S) and c. 896_c.897insA (p.N299fs*2) (NM_016955), which were inherited from her father and mother, respectively. Neither of her parents had related clinical manifestations. According to the ACMG guidelines, the c. 194A>G (p.N65S) variant was classified as pathogenic (PM1+ PM2_Supporting+ PM3+ PP3), and the c. 896_c.897insA (p.N299fs*2) variant was as likely pathogenic (PVS1+ PM2_Supporting). A total of 18 relevant literature were retrieved, which have involved 32 patients (including this case). The p. N65S variant has been reported previously, while the p. N299fs*2 variant is novel. Conclusion:Compound heterozygous variants in the SEPSECS gene probably underlay the pathogenesis of PCH2D in this child. Above finding has expanded the mutational and phenotypic spectrum of the SEPSECS gene.

Median arcuate ligament compression syndrome (MALS) presents with atypical clinical manifestations. MALS is rarely reported in pediatric patients but is recognized as an independent risk factor for postoperative hepatic artery thrombosis in liver transplant recipients. We report a case of a pediatric liver transplant recipient with hepatolenticular degeneration, cirrhosis, and acute liver failure. Despite undergoing artificial liver support therapy, the patient showed no significant improvement in liver function and subsequently underwent liver transplantation. Intraoperatively, weak arterial pulsation and the absence of a pulsatile waveform in the hepatic artery anastomosis raised suspicion of MALS. The condition was successfully managed by releasing and transecting the median arcuate ligament, along with ligation of the splenic and left gastric arteries. To optimize transplantation outcomes, meticulous preoperative imaging assessment, particularly focusing on characteristic findings in CT angiography, is essential. Additionally, individualized surgical planning and intraoperative adjustments based on ultrasound monitoring and arterial pulsation assessments are critical for ensuring successful transplantation.

Objective:To explore clinical characteristics of multiple sclerosis(MS)patients in Suzhou,and to analyze main factors affecting their prognosis.Methods:General data,clinical symptoms,cerebrospinal fluid and imaging examinations of 51 MS patients admitted to Department of Neurology of the Second Hospital of Soochow University from July 31,2009 to July 31,2021 were retrospectively analyzed,and main factors affecting their prognosis were discussed.Results:Average age of onset of 51 MS patients was(43.3±15.6)years old,female accounted for 56.9%,male/female=1/1.3.Adult onset MS(AOMS)accounted for 62.8%,male/female=1/1.7;late onset MS(LOMS)accounted for 37.2%,male/female=1/0.9.Relapsing remitting MS(RRMS)accounted for 76.5%,and chronic onset accounted for 60.8%.Average annual recurrence rate was 8.8%.The first symptoms were numbness and weakness of limbs.Dizziness and numbness were more common in patients without recurrence after diagnosis of MS,and limb weak-ness and numbness were more common in patients with recurrence.Among lesions of MRI,62.7%(32/51)of periventricular involve-ment,52.9%(27/51)of spinal cord involvement,51.0%(26/51)of infratentorial involvement.Proportion of subtentorial and spinal cord(cervical,thoracic)involved were significantly higher in patients with recurrent MS than without recurrence.Values of albumin,IgG,IgA and IgM in cerebrospinal fluid increased with increase of recurrence times.EDSS score of male was higher than female,and LOMS score was higher than AOMS.MS patients without relapse had a low EDSS score,and median EDSS score at current follow-up was 0(0,1.00)score.MS score with relapse was relatively high,and median EDSS score at current follow-up was 2.75(0.25,7.25)score.Conclusion:MS patients with chronic onset are more common,with a high proportion of LOMS,and proportion of males increases with increasing age of onset.High EDSS score at first onset,cervical,thoracic and subtentorial lesions,increased values of cerebrospinal fluid albumin,IgG,IgA,IgM,age at first onset(50+years old),male associate with poor MS prognosis.

Objective:To investigate the clinical application of ultrasound-guided percutaneous catheter drainage in the management of pediatric pancreatitis, delineate the indications, and assess the efficacy and safety of the procedure.Methods:A retrospective case analysis.Eighteen patients who underwent ultrasound-guided percutaneous drainage at Children′s Hospital of Chongqing Medical University from September 2018 to January 2023 were conducted.The cohort comprised 10 males and 8 females aged 1 year 4 months to 15 years and 9 months.The causes of disease were traumatic pancreatitis (9 cases), acute pancreatitis (8 cases), and recurrent pancreatitis (1 case).The disease duration ranged from 1 day to 5 months.The indications for the procedure included acute peripancreatic fluid collection with infection and peritonitis, pancreatic pseudocyst, progressive increase of acute peripancreatic fluid collection, or compression symptoms.Patients′ clinical data, including drainage site, drainage condition, puncture technique, puncture success rate and puncture complications, were collected and analyzed.Results:Nineteen drainage procedures were all successfully performed on the 18 children, and no puncture injury, drainage tube obstruction, drainage tube infection, and other complications were observed.Postoperative drainage volume on the first day ranged from 100 mL to 1 010 mL.Postoperative catheterization time spanned from 6 to 93 days, with a median of 29 days.One patient experienced drainage tube displacement after surgery, and one patient progressed to chronic pancreatitis.The remaining patients achieved clinical cure and had their drainage tubes removed.No serious short-term or long-term complications were noted postoperatively.Conclusions:Ultrasound-guided percutaneous drainage emerges as an effective therapeutic approach for children with acute pancreatitis, offering advantages such as favorable efficacy, straightforward operation, high safety, and minimal trauma.

As a common pathological state in clinical practice， Chong Mai Wei Bing （冲脉为病） is typically manifested as rebellious qi and a sense of urgency. It often involves various diseases caused by the disorder of qi circulation. From the perspectives of theoretical foundation， pathological characteristics， and clinical differentiation and treatment， this paper elaborates on the characteristics of Chong Mai （冲脉） as the cause of disease， including three main manifestations： upward qi surge， upward yin fire， and upward water-qi. Among these， the upward qi surge is further categorized into four aspects： Chong Qi （冲气） counterflow， counterflow of stomach qi， counterflow of kidney qi， and counterflow of liver qi. Three major treatment methods are proposed： pacifying the Chong Mai and reversing the counterflow， consolidating Chong Mai to subdue fire， and warming Chong Mai to resolve qi and promote water flow. This paper summarizes its practical application in clinical diagnosis and treatment， aiming to deepen the understanding of the functional and pathological mechanisms of Chong Mai， and to provide insights and methods for the traditional Chinese medicine diagnosis and treatment of various diseases.

ObjectiveTo systematically evaluate the effect of art therapy on the mental health of older adults with mild cognitive impairment (MCI), based on International Classification of Functioning, Disability and Health. MethodsLiterature on art therapy for mental health of MCI older adults was retrieved from databases of CNKI, VIP, Wanfang Data, PubMed, ProQuest and Web of Science, between 2014 and 2024, and selected according to inclusion and exclusion criteria. The quality of the literature was assessed using PEDro scale, and a systematic review was conducted following the PRISMA guideline. ResultsA total of nine researches were included from China, Tanzania, Spain, Malaysia and Singapore, involving 763 individuals with MCI aged 60 or more (average 71.23). The types of art therapy interventions were visual arts therapy (painting, collage, paper-cutting, sculpture and modeling, etc.), expressive arts therapy (encompassing dance and music) and creative arts therapy (narrative creation), 30 to 120 minutes a time (majority of 60 minutes), one to four times a week (majority of two to four times), for six to 36 weeks (majority of six to twelve weeks). Health outcomes predominantly focused on mental health, such as anxiety and depression. ConclusionMost researches support that art therapy is effective on mental health of older adults with MCI, but there are disagreements in some researches, and more researches are needed.
