Wilson disease （WD） is one of the few treatable neurogenetic disorders. Currently， Western medicine remains the main treatment method for WD， while since the 1990s， multiple studies conducted by Professor Yang Renmin and his team have shown that traditional Chinese medicine （TCM） also has a favorable therapeutic effect. Based on the principle of low-copper diet for WD， this article systematically elaborates on the advantages， limitations， and key considerations of current Western medicine therapies （pharmacotherapy， liver transplantation， and splenectomy） and reviews the research findings of TCM in China， especially the wide application of Gandou Decoction in clinical practice. Studies have shown that Gandou Decoction can effectively improve neurological symptoms， protect hepatic and renal function， and avoid the adverse drug reactions associated with metal chelating agents， and therefore， it can be used an effective long-term adjuvant therapy for WD. It should be noted that symptoms and signs should be considered in integrated traditional Chinese and Western medicine therapy for WD， and high-copper TCM drugs should be avoided to prevent deterioration.

Objective: To investigate the epidemiological characteristics, outcome patterns, and management strategies for blood donors with a positive direct antiglobulin test (DAT). Methods: A retrospective analysis was conducted on donation data from 808 386 donors from 2013 to 2023, focusing on those whose blood was discarded due to DAT positivity. Follow-up was performed on 125 DAT-positive donors, and 98 blood samples were collected. The samples were re-tested for DAT, DAT typing (IgG/C3d), and unexpected antibody screening using both the tube method and the microcolumn gel method. Results: Epidemiological characteristics: Retrospective data revealed 147 DAT-positive blood donors, yielding a positivity rate of 1/5 500. The DAT positivity rate using the tube method was 0.118‰ (49/416 893), lower than that of the microcolumn gel method at 0.25‰ (98/391 493). Among DAT-positive individuals, 44.2% (65/147) exhibited agglutination intensity<2+. Outcome analysis: The proportion of donors with positive DAT test results that converted to negative was 54.1% (53/98), with a conversion interval ranging from 8 to 117 months (mean 49.9 months). All donors in the negative conversion group had a previous DAT intensity<2+, whereas 95.6% (43/45) of the non-negative conversion group had intensity ≥2+ (P<0.001). Unexpected antibodies (anti-E, anti-M, etc.) were detected in 18 cases. Methodological differences: Review of results revealed 35 cases positive by both the DAT tube assay and microcolumn gel method. An additional 10 cases were positive by only one method: 5 were positive only by the tube assay, and 5 were positive only by the microcolumn gel method. Clinical validation: Among 14 DAT-positive donors who became negative and donated blood again, the clinical infusion efficacy of red blood cell products could be assessed in 10 cases, with 9 cases demonstrating effective infusion. Conclusion: Some DAT-positive blood donors may naturally convert to negative status, with the intensity of previous test results potentially serving as a key predictive factor for conversion. It is recommended to employ a combined approach of tube-based and microcolumn gel-based methods for retesting, concurrently screening for irregular antibodies. A tentative tiered management strategy is proposed: individuals with DAT intensity <2+ should be deferred for 12 months before retesting, while those with ≥2+ intensity should be permanently deferred.

Abdominal aortic aneurysm (AAA) is a deadly condition of the aorta, carrying a significant risk of death upon rupture. Currently, there is a dearth of efficacious pharmaceutical interventions to impede the advancement of AAA and avert it from rupturing. Here, we investigated dihydromyricetin (DHM), one of the predominant bioactive flavonoids in Ampelopsis grossedentata (A. grossedentata), as a potential agent for inhibiting AAA. DHM effectively blocked the formation of AAA in angiotensin II-infused apolipoprotein E-deficient (ApoE^-/-) mice. A combination of network pharmacology and whole transcriptome sequencing analysis revealed that DHM's anti-AAA action is linked to heme oxygenase (HO)-1 (Hmox-1 for the rodent gene) and hypoxia-inducible factor (HIF)-1α in vascular smooth muscle cells (VSMCs). Remarkably, DHM caused a robust rise (∼10-fold) of HO-1 protein expression in VSMCs, thereby suppressing VSMC inflammation and oxidative stress and preserving the VSMC contractile phenotype. Intriguingly, the therapeutic effect of DHM on AAA was largely abrogated by VSMC-specific Hmox1 knockdown in mice. Mechanistically, on one hand, DHM increased the transcription of Hmox-1 by triggering the nuclear translocation and activation of HIF-1α, but not nuclear factor erythroid 2-related factor 2 (NRF2). On the other hand, molecular docking, combined with cellular thermal shift assay (CETSA), isothermal titration calorimetry (ITC), drug affinity responsive target stability (DARTS), co-immunoprecipitation (Co-IP), and site mutant experiments revealed that DHM bonded to HO-1 at Lys243 and prevented its degradation, thereby resulting in considerable HO-1 buildup. In summary, our findings suggest that naturally derived DHM has the capacity to markedly enhance HO-1 expression in VSMCs, which may hold promise as a therapeutic strategy for AAA.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Objective:To describe the distribution characteristics of alcohol consumption in adult twins in the Chinese National Twin Registry (CNTR), and further explore the influence of genetic factors on alcohol consumption in adult twins.Methods:The subjects of the study were twins registered by CNTR in 11 project areas across China from 2010 to 2018. A total of 56 966 twins (28 483 pairs) aged 18 years and above who answered questions about drinking behavior were included, and the random effect model was used to describe the population and regional distribution characteristics of alcohol consumption. Intra-pair analysis was performed to calculate the concordance rate and heritability of their alcohol consumption.Results:The age of all subjects was (36.6±12.0) years, and current drinkers accounted for 16.6% (9 461/56 966) of all subjects. In men, those aged 50-59 years, those in northern China, those living in rural area, those with low education level and those with high BMI, the proportions of current drinkers were higher. After excluding 468 pairs of twins who had stopped alcohol use and 21 764 pairs of twins who had no drink or had small amount drink, an intra-pair analysis was conducted in 4 929 pairs of same-sex twins, and found that the concordance rate of alcohol consumption was 64.0% (2 059/3 215) in monozygotic twins, and 52.6% (902/1 714) in dizygotic twins, the difference was significant ( P<0.001), and the heritability of alcohol consumption was 24.1% (95% CI: 18.9%- 29.3%). The further stratified analysis found that in southern men, the heritability was highest in those aged 40-49 years (36.1%, 95% CI: 21.6%-50.7%), while in northern men, the heritability was highest in those aged 50-59 years (34.2%, 95% CI: 18.1%-50.3%). Conclusions:In adult twins in China, there were population and regional differences in the distribution of alcohol consumption behavior, and alcohol consumption was influenced by genetic factors, and gender, age and region had potential modifying effects.

Objective:To observe the expression level of long noncoding RNA RP11-97C16.1 in bladder cancer tissues and its relationship with the survival time of bladder cancer patients, and to explore the role and potential molecular mechanism of RP11-97C16.1 in the proliferation of bladder cancer cells.Methods:The expression difference of RP11-97C16.1 in bladder cancer tissue and adjacent tissue was analyzed by TCGA database, and the relationship between the expression level of RP11-97C16.1 and the survival time of bladder cancer patients was analyzed by GEPIA database. The expression of RP11-97C16.1 in four bladder cancer cell lines (T24, MGH-U3, J82, UM-UC-3) was detected by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR). The UM-UC-3 cells were divided into RP11-97C16.1 group and control group, and the transfectants were pcDNA-RP11-97C16.1 plasmid and negative control plasmid, respectively. The expression levels of RP11-97C16.1 and miR-3687 were detected by RT-qPCR. The viability and proliferation ability of UM-UC-3 cells were detected by cell counting kit-8 (CCK8) and colony formation assay. The complementary relationship between RP11-97C16.1 and miR-3687 was verified by dual-luciferase reporter gene assay. The expression levels of Cyclin E2, CDK2, CDK4, CDK6 and Cyclin D2 were detected by Western blotting. Measurement data were expressed as mean ± standard deviation ( ± s), independent sample t-test was used for comparison between two groups, and one-way analysis of variance was used for comparison between multiple groups. Results:Compared with adjacent tissues, the expression of RP11-97C16.1 in bladder cancer tissues was significantly decreased ( P<0.01). Compared with patients with lower expression of RP11-97C16.1, patients with higher expression of RP11-97C16.1 had longer overall survival time ( P<0.01). Compared with the SV-HUC-1 cell line, the expression of RP11-97C16.1 was significantly decreased in the four bladder cancer cell lines ( P<0.01). In UM-UC-3 cells in which RP11-97C16.1 was upregulated, the expression of miR-3687 was decreased ( P<0.01). Compared with the control group, up-regulation of RP11-97C16.1 could significantly reduce the proliferation ability of UM-UC-3 cells ( P<0.05), and decrease the number of bladder cancer cell colonies ( P<0.01). RP11-97C16.1 could target and bind miR-3687 ( P<0.01). Compared with the control group, overexpression of RP11-97C16.1 could significantly decreased the expression of Cyclin E2, CDK2, CDK4, CDK6, and Cyclin D2 proteins. Conclusions:The expression of RP11-97C16.1 is low in bladder cancer tissue, and patients with higher expression of RP11-97C16.1 have a longer survival time. Up-regulation of RP11-97C16.1 can down-regulate the expression of miR-3687, thereby inhibiting the proliferation of bladder cancer cells UM-UC-3.

Objective To integrate multi-source heterogeneous literature data from China Na-tional Knowledge Infrastructure(CNKI),Wanfang,VIP,and Web of Science(WoS)databases u-sing bibliometric methods,and to comparatively analyze the differences in knowledge structure charac-teristics and evolutionary pathways of organoid research between China and foreign countries.Meth-ods CiteSpace software was employed to conduct a visual atlas analysis of the publication volume,countries,institutions,authors,and keywords of 1,118 Chinese literatures and 10,871 English lit-eratures.Results China ranked the second globally in terms of publication volume(accounting for 22.09％),but exhibited low centrality in international collaboration networks.The density of the do-mestic institutional collaboration network was 0.003,indicating a relatively loose structure,with Fudan University leading domestic output with 15 Chinese papers.Keyword emergence analysis revealed that"organ-on-a-chip"and"biomechanics"have emerged as new hotspots since 2024.Conclusion It is recommended to establish an interdisciplinary collaborative innovation alliance to focus on break-throughs in the translational directions of organ-on-a-chip and biomechanics,thereby addressing the imbalance between"scale and quality"in China's organoid research.

Objective: To explore the effect of different obesity indicators in predicting cardiovascular and cerebrovascular diseases (CVD) risk among patients with type 2 diabetes mellitus (T2DM), so as to provide the evidence for the early identification of CVD risk among T2DM patients. Methods: The patients with T2DM under community management in Qingpu District, Shanghai Municipality were selected as the study subjects in January 2025. Basic information such as gender, age, and blood glucose control status were collected through the Shanghai Chronic Disease Information Management System, while history of CVD were obtained from residents' electronic health records and the Shanghai Disease Control Information Platform. Obesity was assessed using body mass index (BMI), waist circumference (WC), BMI combined with WC, waist-to-height ratio (WHtR), and triglyceride (TG) combined with WC indicators. The association between obesity and CVD was analyzed using multivariable logistic regression models. The predictive effect of each obesity indicators for CVD was evaluated using the area under the receiver operating characteristic curve (AUC). Results: A total of 4 367 patients with T2DM were included, including 2 121 males (48.57%) and 2 246 females (51.43%). The average age was (68.71±8.05) years. The prevalence of CVD was 44.49%. Multivariable logistic regression analysis showed that after adjusting for age, education level, history of hypertension, duration of T2DM, use of glucose-lowering medications, renal function, and blood glucose control status, obese T2DM patients had a 389.4% increased risk of CVD compared to those with normal BMI; centrally obese T2DM patients had a 100.4% increased risk compared to those with normal WC; T2DM patients with isolated general obesity and compound obesity had 161.0% and 241.1% increased risks of CVD, respectively, compared to those with normal BMI and WC; centrally obese T2DM patients had a 100.4% increased risk compared to those with normal WHtR; T2DM patients with normal TG-high WC and high TG-high WC phenotypes had 83.1% and 68.8% increased risks of CVD, respectively, compared to those with normal TG and normal WC (all P<0.05). BMI had the highest AUC, at 0.714, with sensitivity and specificity of 0.675 and 0.642, respectively. This was followed by BMI combined with WC, which had an AUC of 0.707, with sensitivity and specificity of 0.635 and 0.679, respectively. Conclusions Obesity defined by BMI, WC, BMI combined with WC, WHtR, and TG combined with WC increases the risk of CVD among patients with T2DM. BMI and BMI combined with WC have better predictive effect in predicting CVD risk among patients with T2DM, and can be used as the primary obesity indicators for CVD risk screening.

Objective:To compare the clinical efficacy of robot-assisted balloon tibioplasty and traditional open reduction and internal fixation in the treatment of AO/OTA type 41B2 tibial plateau fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 70 patients with AO/OTA type 41B2 tibial plateau fracture who were admitted to Wuhan Fourth Hospital from September 2019 to October 2022, including 35 males and 35 females, aged 24-62 years [(44.9±9.5)years]. Among them, 41 patients underwent traditional open reduction and internal fixation (open reduction group), while 29 patients underwent robot-assisted balloon tibioplasty (balloon group). The following parameters were compared between the two groups: incision length, operative blood loss, number of intraoperative fluoroscopies, operation duration, and length of hospital stay; Rasmussen radiological scores at 3 days, 3 months postoperatively, and at the last follow-up and the fracture healing time; pain visual analogue scale (VAS) scores preoperatively, and at 2 days and 3 months postoperatively; knee joint range of motion at 5 days, 3 months postoperatively, and at the last follow-up; Hospital for Special Surgery (HSS) knee function scores at 3, 6 months postoperatively, and at the last follow-up; incidence rate of complications at 15 days postoperatively.Results:All the patients were followed for 12-24 months [18(17, 20)months]. The incision length, operative blood loss and length of hospital stay in the balloon group were 1.6(1.5, 3.0)cm, 5.0(5.0, 5.0)ml and 11.0(9.0, 14.0)days, less than those in the open reduction group [12.0(11.0, 12.0)cm, 100.0(50.0, 120.0)ml and 15.0(13.0, 20.0)days] ( P<0.01). The number of intraoperative fluoroscopies and operation duration in the open reduction group were 9.0(7.0, 10.0)times and 75.0(60.0, 90.0)minutes, less than those in the balloon group [336.0(335.0, 340.0)times and [90.0(70.0, 105.0)minutes] ( P<0.05). There were no significant differences in the Rasmussen radiological scores between the two groups at 3 days, 3 months postoperatively, or at the last follow-up ( P>0.05). The fracture healing time in the balloon group was 3.0(3.0, 3.0)months, shorter than 3.0(3.0, 3.5)months in the open reduction group ( P<0.05). No significant differences were observed between the two groups in VAS scores before operation or at 3 months postoperatively ( P>0.05). However, the VAS score was 2.0(2.0, 3.0)points at 2 days postoperatively in the balloon group, lower than 5.0(5.0, 6.0)points in the open reduction group ( P<0.01). The knee joint range of motion at 5 days, 3 months postoperatively and at the last follow-up were 90.0(85.0, 90.0)°, 135.0(130.0, 135.0)° and 140.0(135.0, 140.0)° in the balloon group, better than 65.0(60.0, 70.0)°, 125.0(120.0, 130.0)°, 130.0(130.0, 140.0)° in the open reduction group ( P<0.01). Similarly, the HSS knee function scores at 3, 6 months postoperatively and at the last follow-up were 80.0(80.0, 81.0)points, 91.0(90.0, 92.0)points, and 95.0(93.0, 96.0)points in the balloon group, better than 71.0(70.0, 72.0)points, 83.0(81.0, 84.0)points, and 86.0(84.0, 88.0)points in the open reduction group ( P<0.01). The incidence rate of complications in the balloon group was 0, comparable to 12% (5/41) in the open reduction group ( P>0.05). Conclusion:Compared with traditional open reduction and internal fixation surgery, robot-assisted balloon tibioplasty in the treatment of AO/OTA type 41B2 tibial plateau fracture significantly reduces surgical trauma, alleviates postoperative pain, promotes fracture healing, and accelerates functional recovery of the affected limbs.
