Objective To investigate the registration rate and trend of pulmonary tuberculosis complicated with diabetes mellitus (PTB-DM) in Wuhan from 2020 to 2024, and to provide scientific evidence for formulating PTB-DM prevention and control policies. Methods PTB-DM case data in Wuhan (2020-2024) were collected through the Infectious Disease Registration and Management Information System. Joinpoint regression model was employed to analyze the trend of registration rates of PTB-DM among the general population and across different regions, genders, and age groups. ARIMA model was used to predict the short-term prevalence of PTB-DM. Results Among 26275 pulmonary tuberculosis cases registered in Wuhan (2020-2024), 2669 cases (10.16%) were PTB-DM. The average annual registration rate of PTB-DM was 3.96/100,000, increasing from 2.74/100,000 in 2020 to 5.40/100,000 in 2024 (APC=19.07%, 95% CI:12.99%-26.92%, P<0.001). The PTB-DM registration rates showed an upward trend across different regions, genders, and age groups in Wuhan, with higher registration rates observed in near urban area, males, and individuals aged 60~64 and 65 years and above (χ²=99.566, P<0.001; χ²=781.891, P<0.001; χ²=2211.930, P<0.001). ARIMA model predicted that the prevalence of PTB-DM in Wuhan would remain stable and fluctuating in the short time. Conclusion PTB-DM registration rate in Wuhan increases from 2020 to 2024. Near urban area, males, and elderly populations are high risk groups. Future efforts should focus on strengthening the prevention and control of PTB-DM among these populations.

ObjectiveTo investigate the effects of different antiplatelet therapy regimens （aspirin versus clopidogrel at specific doses） on cognitive function， blood biomarkers and brain imaging biomarkers when used prophylactically in patients with cerebral small vessel disease （CSVD）. MethodsA randomized controlled trial was conducted involving 160 CSVD patients who were randomly assigned to four groups： aspirin group （ASA）， low-dose clopidogrel group （CLOP-50）， standard-dose clopidogrel group （CLOP-75）， and control group （HC）. Cognitive function ［auditory verbal learning test-immediate recall （AVLT-IR）， auditory verbal learning test-short-delay recall （AVLT-SDR）， auditory verbal learning test-long-delay recall （AVLT-LDR）， hamilton anxiety rating scale （HAMA）， and hamilton depression rating scale （HAMD）， ADL（activities of daily living scale ）， （ascertain dementia 8-item questionnaire，AD8）］， blood biomarkers ［platelet count （PLT） and mean platelet volume （MPV）］， and CSVD-related imaging biomarkers ［white matter hyperintensities （WMH） and cerebral microbleeds （CMB）］ were assessed in all groups at baseline and at the 6-month follow-up. ResultsAfter 6 months of treatment， within-group comparisons showed that， compared with baseline， the ASA group had significantly increased scores on the AVLT immediate recall （AVLT-IR）， short-delay recall （AVLT-SDR）， and long-delay recall （AVLT-LDR） （P<0.05）. The CLOP-75 group showed significantly decreased HAMA and HAMD scores （P<0.05）， along with a significant increase in AVLT-LDR scores （P<0.05）. The number of CMBs increased from baseline in both the ASA and CLOP-75 groups （P<0.05）， whereas no statistically significant changes in blood biomarkers were observed in either group. By contrast， the CLOP-50 and HC groups showed no significant changes in cognitive function， blood biomarkers， or CSVD-related imaging biomarkers compared with baseline （all P<0.05）. Comparisons between groups showed that the AVLT-LDR scores and the number of CMBs increased faster in the ASA group than in the HC group （β=-0.187， P=0.04； β=-0.805， P<0.001）. In addition， the rate of CMB increase was also faster in the ASA group than in the CLOP-50 group （β=-0.695， P<0.01）. The ADL scores increased faster in the HC group than in the ASA group （β=0.170， P=0.02）. The AD8 scores decreased faster in the CLOP-75 group than in the HC group （β=-0.128， P=0.04）， but the rate of CMB increase in the CLOP-75 group was also faster than that in the HC group （β=0.604， P=0.04）. ConclusionIn CSVD patients， aspirin 100 mg or clopidogrel 75 mg improves cognitive function but increases the risk of cerebral hemorrhage. Clopidogrel 50 mg shows no short-term clinical benefit or imaging improvement.

OBJECTIVE To investigate and control a suspected outbreak of hospital-associated Elizabethkingia a-nopheles infection in respiratory intensive care unit(RICU),and provide scientific basis for effective prevention and control of hospital-associated E.anophelis infection.METHODS The tracking source analysis was performed for 9 identified cases who were detected with E.anophelis through epidemiological survey,environmental hy-giene monitoring and endoscopic cavity visualization system,the surroundings that they contacted and the instru-ments they were treated with were investigated.The targeted prevention and control measures were implemented.RESULTS A total of 55 samples were collected from the surrounding environment and shared instru-ments of 9 patients detected with E.anophelis.Totally 6 samples were detected positive for the environmental ob-ject surfaces of 3 patients,and 15 positive samples were identified as the same source by homology analysis.Two faulty bronchoscopes were found through the visualization system of lumen instruments.CONCLUSIONS There are multiple pathways of cross-contamination of bronchoscope and person-to person transmission of E.anophelis in RICU.Strengthening the management of cleaning and disinfection of bronchoscope,increasing the frequency of cleaning and disinfection of RICU environmental surfaces and improving the compliance of hand hy-giene of medical staff are important measures to control the outbreak of hospital-associated infection.

The advent of bruton tyrosine kinase inhibitors (BTKi) has offered more therapeutic choices for patients with B-cell malignancies. However, with its widespread application in recent years, the use of BTKi increases the risk of severe infections in patients. Here, we report three cases of B-cell malignancies, including one case of chronic lymphocytic leukemia and two cases of diffuse large B-cell lymphoma. During treatment with BTKi zanubrutinib, different degrees of invasive fungal disease (IFD) of the central nervous system occurred in these patients. All patients fully recovered following antifungal therapy. With a median follow-up of 35 months, all patients remained in a continuous remission state, and none of them had a recurrence of IFD.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

A 58-year-old female patient presented with erythema on the right shoulder and chest for 8 years. The appearance of erythema was concurrent with numbness and weakness in both lower limbs, elevated peripheral blood M protein levels, thyroid dysfunction, and multiple enlarged lymph nodes in the right axilla, leading to a diagnosis of POEMS syndrome. After autologous hematopoietic stem cell transplantation, erythema subsided but recurred 1 year prior to this visit. Physical examination revealed a pigeon egg-sized swollen lymph node on the right side of the neck. Skin examination showed patchy erythema on the right shoulder and chest, with clear boundaries and a hard texture. Serum protein electrophoresis revealed an elevated M protein level, and serum immunofixation electrophoresis showed a restricted IgG λ band. In addition, peripheral blood levels of vascular endothelial growth factor were elevated. Computed tomography scan images showed an irregular flaky bone destruction area at the acromion end of the right scapula, which was consistent with the manifestations of bone plasmacytoma. Histopathological examination of the skin tissue in the right shoulder revealed a large number of dilated and proliferative vessels between dermal collagen fibers, and the patient was diagnosed with AESOP syndrome. Lenalidomide combined with dexamethasone chemotherapy was administered. After three cycles of treatment, M protein turned negative, and erythema became darker in color, and decreased in size compared with the skin lesion before treatment.

Crohn's disease (CD), a chronic and recurrent inflammatory bowel disease, requires repeated intestinal evaluations. As a non-radioactive, non-invasive, well-tolerated, inexpensive and easily reproducible detection tool, intestinal ultrasound (IUS) has been more and more widely used in the diagnosis and treatment of CD in recent years. Various parameters of IUS, such as bowel wall thickness, bowel wall stratification, color doppler signals, and inflammatory mesenteric fat, provide a lot of critical information in the diagnosis and treatment of CD. IUS can not only accurately diagnose CD and its complications, but also well evaluate CD disease activity and treatment response, and effectively predict CD transmural remission, disease duration, surgical risk, and postoperative recurrence. IUS has demonstrated good accuracy in the diagnosis, evaluation and prediction of CD.

Objective:To analyze the clinical features and diagnostic process of ring chromosome syndrome.Methods:Clinical data of 9 children with ring chromosome syndrome who were treated at the Children′s Medical Center of Peking University First Hospital from September 2009 to May 2025, were summarized and analyzed in a case series study. The data included clinical manifestations, types of epileptic seizures, genetic testing, treatment outcomes, and follow-up results, et al.Results:Among the 9 children with ring chromosome syndrome, there were 6 girls and 3 boys, including 4 children with ring chromosome 20 syndrome, 3 children with ring chromosome 14 syndrome, and 1 child each with ring chromosome 13 and 17 syndrome. All 9 children had de novo chromosomal variations. Among them, 3 children of ring chromosome 20 syndrome were mosaic, and the remaining 6 children were non-mosaic. All 9 children exhibited diverse clinical features, especially those with ring chromosome 20 syndrome, which presented with specific manifestations. The 4 children with ring chromosome 20 syndrome all had acute epileptic seizures as the initial symptom, with onset ages of 67, 39, 17, and 96 months, and all had focal seizures. One child with ring chromosome 20 syndrome had non-convulsive status epilepticus. Development of all 4 children with ring chromosome 20 syndrome was normal before seizure onset, but 3 children showed regression after onset. No physical deformities were observed in 4 children with ring chromosome 20 syndrome, and 2 children were misdiagnosed, 3 children underwent whole exome sequencing and copy number variation analysis in their families, with no abnormalities detected. All 4 children with ring chromosome 20 syndrome were diagnosed through chromosomal karyotype analysis, the intervals between onset and diagnosis were 2, 81, 19 and 13 months, respectively. Follow-up showed that epileptic seizures were not controlled in all 4 children with ring chromosome 20 syndrome. The other 5 children were characterized by developmental delay as the initial symptom, followed by epileptic seizures between 3 and 24 months of age. Developmental regression of the other 5 children did not occur after onset, 2 of them had microcephaly, and 3 had wide-set eyes. No misdiagnoses were reported in these 5 children, and the intervals between onset and diagnosis were 7, 3, 55, 3, and 106 months, respectively. Follow-up showed that epileptic seizures were controlled in these 5 children. Conclusions:Ring chromosome 20 syndrome typically manifest with epilepsy as the initial symptom and are refractory to drug treatment, their early development is entirely normal. Ring chromosome 13, 14, and 17 syndrome are characterized by developmental delay from an early age, followed by the onset of epileptic seizures, which are easily controlled. Conventional whole exome sequencing and copy number variation analysis in families rarely detect ring chromosome abnormalities. Early chromosomal karyotype analysis is essential for the diagnosis of ring chromosome syndrome.

Objective:To explore the genetic and clinical characteristics of epilepsy related with ATP6V1A gene heterozygous variants.Methods:A case series study was conducted. The clinical data of 10 children of epilepsy associated with ATP6V1A gene variants who were admitted to the Children′s Medical Center, Peking University First Hospital from January 2019 to December 2024 was collected. The characteristics of children′ gene variation, clinical phenotype, auxiliary examination results, treatment and prognosis were analyzed.Results:Among the 10 children, there were 4 boys and 6 girls. All 10 children with ATP6V1A gene variants were de novo heterozygous variants, including 1 case of mosaic variant. A total of 9 different variants were identified and 7 variants have not been reported previously. The age at epilepsy onset was 28 (9, 48) months. Five children experienced their first seizure as a fever induction. The types of epileptic seizures included focal seizures in 6 children, epileptic spasms in 5 children, tonic spasms and atonic seizures in 1 child respectively. Three children had 2 seizure types. Global developmental delays were exhibited in 8 children, 2 of whom manifested autism spectrum disorder phenotypes. Two children showed normal development. Electroencephalography revealed slowed background activity in 5 children. Interictal epileptiform discharges were recorded in 9 cases, including hypsarrhythmia, focal, multifocal or generalized discharges. Clinical seizures were captured in 4 children. Brain magnetic resonance imaging abnormalities were found in 4 children, including frontotemporal cortical dysplasia, prominent sulci, delayed myelination of white matter, dysplasia of the corpus callosum, bilateral ventricular enlargement, and cerebral atrophy. Five children were diagnosed with developmental and epileptic encephalopathy (DEE), and 4 of them were diagnosed with infantile epileptic spasms syndrome. At the last follow-up, the age was 78 (25, 120) months. Seizures were controlled in 6 children, while 4 children had uncontrolled seizures despite treatment with ≥3 anti-seizure medications. Conclusions:All children with ATP6V1A gene related epilepsy harbored de novo heterozygous missense variants, with few showing mosaic variants. Seizure onset age ranged widely from the neonatal period to childhood. The predominant seizure types were focal seizures and epileptic spasms. The phenotypic spectrum may exhibit DEE, while a minority maintain normal development.

Objective To evaluate the efficacy of intravascular intervention in the treatment of multiple intracranial aneurysms(MIAs).Methods The clinical data of MIAs patients,who were treated with intravascular intervention from December 2013 to December 2021 in Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine,were collected and were analyzed by using statistical methods.Results A total of 105 MIAs patients were enrolled in this study,and among them 77 patients(73.3％)were complicated by subarachnoid haemorrhage.Intravascular intervention was performed for 192 of the 240(80.0％)intracranial aneurysms(I As),including 142 IAs receiving one-stage treatment and 50 IAs receiving multi-stage treatment.In 66 patients,all the IAs were treated.Simple spring coil embolization was performed for 84 IAs and stent-assisted spring coil embolization was carried out for 108 IAs.During the follow-up period,11 patients developed recurrent IAs,which received treatment again.There was no obvious statistical difference in the treatment results between the patients receiving one-stage treatment and the patients receiving multi-stage treatment(P＞0.05).There was also no obvious statistical difference in the follow-up findings and prognosis results between the patients receiving one-stage treatment and the patients receiving multi-stage treatment(P＞0.05).Conclusion For the treatment of MIAs,the clinical efficacy of one-stage intravascular treatment and multi-stage intravascular treatment is roughly the same.However,one-stage treatment should be adopted as far as possible when the technical conditions permit.
