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.

Objective To observe the effects of Jianpi Huatan Prescription on hepatic cholesterol synthesis in subclinical hypothyroidism(SCH)mice;To discuss its mechanism based on cAMP/CREB/HMGCR signaling pathway.Methods Totally 80 C57BL/6 male mice were randomly divided into control group(10 mice)and modeling group(70 mice),and the modeling group was given methimazole 0.08 mg/(kg·d)in drinking water for 16 weeks to establish a SCH mdoel.The model mice were randomly divided into model group,euthyrox group and Jianpi Huatan Prescription high-,medium-and low-dosage groups,with 10 mice in each group,and were given corresponding drugs for gavage for 6 weeks.HE staining and Oil red O staining were used to observe the morphology and lipid deposition of liver tissue,ELISA was used to detect serum contents of thyroid stimulating hormone(TSH),triiodothyronine(T3),thyroid hormone(T4),total cholesterol(TC),triglycerides(TG),and TC,cyclic adenosine monophosphate(cAMP)in liver tissue,Western blot was used to detect the expressions of protein kinase A(PKA),cyclic adenosine response element binding protein(CREB),p-CREB and 3-hydroxy-3-methylglutaryl-CoA reductase(HMGCR)in liver tissue.Results Compared with the control group,the liver tissue of mice in the model group showed fat vacuoles of different sizes and obvious lipid deposition;the contents of TSH,TC,TG in serum and TC,cAMP in liver tissue significantly increased(P＜0.05,P＜0.01);the protein expressions of PKA,p-CREB and HMGCR significantly increased(P＜0.01).Compared with the model group,lipid deposition in liver tissue and structure of liver cells was improved to varying degrees in euthyrox group and Jianpi Huatan Prescription high-and medium-dosage groups,and the contents of serum TSH,TC,TG,and liver tissue TC,cAMP decreased(P＜0.05,P＜0.01);the expressions of PKA,p-CREB and HMGCR protein in liver tissue increased significantly(P＜0.01).Conclusion Jianpi Huatan Prescription can significantly inhibit hepatic cholesterol synthesis in SCH mice,and improve hepatic fat vacuoles and lipid deposition,and its mechanism may be to reduce TSH levels in SCH mice by regulating the cAMP/CREB/HMGCR signaling pathway.

Objective To explore the value of the combination of multi-detector row helical CT(MDCT)enhancement and multi-dimensional CT angiography(CTA)in preoperative diagnosis of hypervascular tumors in maxillofacial soft tissues.Methods Eighty-six patients with oral and maxillofacial soft tissue tumors were enrolled and examined with MDCT enhancement combined with multi-dimensional CTA.Κappa test was used to analyze the consistency of the proposed technology with pathological examination as the gold standard for determining benign and malignant tumors.The blood supplies(CT values of plain scan,arterial phase,venous phase,arterial-phase net enhancement and venous-phase net enhancement)of benign and malignant tumors were compared.The diagnostic value of different vascular CT values for tumor properties was evaluated with ROC curves.Results Pathological examination identified 50 benign cases and 36 malignant cases out of 86 patients with oral and maxillofacial soft tissue tumors.Thirty-four cases were diagnosed as malignant tumors when using MDCT enhancement combined with multi-dimensional CTA,and there were 32 confirmed cases,2 misdiagnosed cases and 4 missed cases.The consistency of the proposed technology with pathological examination for diagnosing benign and malignant tumors was 0.878.Benign group had lower CT values of arterial phase,venous phase,arterial-phase net enhancement and venous-phase net enhancement than malignant group(P<0.05).The results of ROC curves revealed that the CT values of arterial phase,venous phase,arterial-phase net enhancement and venous-phase net enhancement were of high differential diagnostic value in tumor properties(AUC=0.778,0.745,0.738 and 0.781,respectively;P<0.05).Conclusion The combination of MDCT enhancement and multi-dimensional CTA provides significant guidance for the diagnosis of hypervascular tumors in maxillofacial soft tissues.

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.

Objective To analyze the characteristics of MR amide proton transfer(APT)imaging and enhancement signals in benign and malignant muscular soft tissue tumors and to explore the value of MR APT imaging,contrast enhancement techniques,and their combined application in the differential diagnosis of benign and malignant muscular soft tissue tumors.Methods A retrospective analysis was conducted on 34 patients with muscular soft tissue tumors confirmed by pathology,including 13 malignant and 21 benign.All patients underwent both MR with contrast enhancement and APT imaging examinations before surgery.APT values were obtained through post-processing on an image workstation.The enhancement signal characteristics and APT values were compared between benign and malignant muscular soft tissue tumors.The receiver operating characteristic(ROC)curve was used to analyze the diagnostic efficacy of the two techniques alone and in combination for differentiating between benign and malignant muscular soft tissue tumors.Results There were significant differences in enhancement signal characteristics on MR and APT values between benign and malignant muscular soft tissue tumors(P<0.05).The enhancement signal of malignant tumors was more heterogeneous,with higher enhancement degree than benign tumors;the APT value of benign tumors was(2.20±0.93)%,and the APT value of malignant tumors was(3.52±0.83)%,the ROC curve analysis determined a cutoff APT value of 2.82%for malignant tumors,with a diagnostic specificity of 90.5%and sensitivity of 76.9%.The area under the curve(AUC)for MR with contrast enhancement,APT imaging,and the combination of the two techniques were 0.694,0.857 and 0.894,respectively.No significant differences were found in the diagnostic efficacy between MR with contrast enhancement and APT imaging(Z=1.587,P=0.112 6)or between APT imaging and the combination of the two tech-niques(Z=1.217,P=0.223 4),but there was significant difference between MR with contrast enhancement and the combination of the two techniques(Z=2.428,P=0.015 2).Moreover,the combination of the two techniques showed the overall highest diag-nostic efficacy.Conclusion The combined application of MR APT imaging and contrast enhancement techniques is more beneficial for the qualitative diagnosis of muscular soft tissue tumors.

Objective:To observe the clinical efficacy of Xinyue Decoction combined with fluoxetine hydrochloride in the treatment of cognitive impairment of senile depression.Methods:A randomized controlled trial study was conducted. Totally 116 elderly patients with depression accompanied by cognitive impairment were set as observation subjects, and were divided into a control group and an experimental group using random number table method, with 58 patients in each. The control group received treatment with fluoxetine hydrochloride capsules, while the experimental group was administered Xinyue Decoction Granules in addition to the treatment regimen of the control group. The treatment lasted for 8 weeks for both groups. Comparison was made between the two groups regarding the changes in TCM syndrome scores. Hamilton Depression Scale (HAMD-24) was used to assess the degree of depression, and Montreal Cognitive Assessment (MoCA BJ) was used to assess cognitive ability; the serum levels of brain-derived neurotrophic factor (BDNF), IL-1β, IL-6 and TNF-α were detected by ELISA; the adverse reactions during treatment were observed and recorded, and the clinical efficacy was evaluated.Results:The total effective rate of TCM syndromes was 90.4% (47/52) in the experimental group and 75.5% (40/53) in the control group, with statistical significance ( χ2=4.11, P<0.05); the total effective rate of MoCA-BJ was 76.9% (40/52) in the experimental group and 58.5% (31/53) in the control group, with statistical significance ( χ2=4.61, P<0.05); the total effective rate of HAMD-24 was 88.5% (46/52) in the experimental group and 71.7% (38/53) in the control group, with statistical significance ( χ2=4.07, P<0.05). After treatment, the TCM syndrome score, HAMD-24 and MoCA-BJ scores of the experimental group were lower than those in the control group ( t=-3.51, -5.11, 2.39, P<0.01 or P<0.05); the level of serum BDNF [(10.49±1.76) ng/L vs. (9.61±1.85) ng/L, t=2.28] in the observation group was higher than that of the control group ( P<0.05), and the levels of IL-1β, IL-6 and TNF-α were lower than those in the control group ( t=-2.50, -2.46, -2.18, P<0.05). During the treatment, the incidence of adverse reactions was 5.77% (3/52) in the experimental group and 7.55% (4/53) in the control group, without statistical significance ( χ2=0.13, P>0.05). Conclusion:Xinyue Decoction combined with fluoxetine hydrochloride can reduce the degree of depression in elderly patients with cognitive impairment of depression, improve the cognitive ability of patients and clinical efficacy.

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 investigate the long-term prognosis and related factors in children with multiphasic myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD).Methods:A bidirectional cohort study was conducted. This study included 41 children with MOGAD who were treated at the Children′s Medical Center of Peking University First Hospital between January 2013 and December 2024, with a disease duration of ≥5 years. Demographic characteristics, clinical episodes, therapy, and prognostic indicators (including the expanded disability status scale (EDSS) and modified Rankin scale (mRS)) were collected. Children were stratified into relapse and non-relapse groups based on the presence or absence of relapse within 5 years of the last follow-up. χ2 test or Mann-Whitney U test was used to analyze factors associated with relapse. The Log-rank test was used to compare relapse-free rates between children with disease onset 0-<5 years and those with onset at 5-10 years. Results:A total of 41 children were enrolled, including 20 boys and 21 girls. The age at onset was 5.3 (3.8, 8.5) years, the age at last follow-up was 16.1 (13.2, 17.5) years, and the disease duration was 9.4 (8.1, 10.9) years. The annualized relapse rate (ARR) during follow-up was 0.34 (0.19, 0.56) times/year. The duration to first relapse was 0.8 (0.4, 1.5) years. At the last follow-up, the EDSS score was 0.0 (0.0, 0.0) score, and the mRS score was 0 (0, 0) score. A total of 40 children (98%) experienced relapses within the first 5 years after onset, while only 1 child (2%) relapsed at 6.7 years. The relapse rate between 5-10 years was lower than that between 0-<5 years ( HR=0.27, 95% CI 0.16-0.47, P<0.001). A total of 25 children (61.0%) exhibited clustered relapses during the disease course. There were 20 children (49%) in non-relapse groups, who were aged 16.6 (14.8, 17.6) years, disease duration 9.8 (9.3, 10.8) years at the last follow-up. Among those 20 children, 15 children (75%) had discontinued corticosteroids and immunosuppressants. The relapse group had higher clinical event rates and ARR compared to the relapse-free group (both P<0.01), the age at last follow-up was yonger ( P<0.05), while no significant differences were observed in age at onset, disease duration, or timing of immunosuppressant use (all P>0.05). Conclusions:Pediatric multiphasic MOGAD generally has a favorable prognosis, about half of patients remain relapse-free for ≥5 years at last follow-up. Relapses predominantly occur early in the disease course (mostly within 5 years of onset) and often exhibit a clustered pattern.

Enamel demineralization, the formation of white spot lesions, is a common issue in clinical orthodontic treatment. The appearance of white spot lesions not only affects the texture and health of dental hard tissues but also impacts the health and aesthetics of teeth after orthodontic treatment. The prevention, diagnosis, and treatment of white spot lesions that occur throughout the orthodontic treatment process involve multiple dental specialties. This expert consensus will focus on providing guiding opinions on the management and prevention of white spot lesions during orthodontic treatment, advocating for proactive prevention, early detection, timely treatment, scientific follow-up, and multidisciplinary management of white spot lesions throughout the orthodontic process, thereby maintaining the dental health of patients during orthodontic treatment.
