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 analyze the epidemiological characteristics of pulmonary tuberculosis (PTB) among college students in Yangzhou from 2020 to 2024, so as to provide a scientific basis for developing prevention and control strategies. Methods: An epidemiological investigation was conducted among 162 college students with PTB, and 7 134 of their contacts were screened. Data were obtained from the tuberculosis information management system and on campus screening records. Using descriptive epidemiological methods, trends in incidence, seasonal distribution, and bacteriological characteristics were analyzed. Results: From 2020 to 2024, the annual average incidence of pulmonary tuberculosis among college students in Yangzhou was 29.42 per 100 000, showing an overall fluctuating downward trend ( χ 2=12.36, P <0.01). Cases were mainly concentrated in summer and autumn, with the highest proportion in autumn (41.36%, 67/162), followed by summer (23.46%, 38/162). The proportion of etiologically positive cases increased from 37.21% in 2020 to 71.43% in 2024; among positive cases, the proportion of latent tuberculosis infection (LTBI) decreased from 66.67% (10/15) to 26.67% (4/15). The etiological positive rate was higher in females than in males ( χ 2= 11.76 , P <0.01). Comparison of screening methods showed that among index cases, the LTBI detection rate of the recombinant Mycobacterium tuberculosis fusion protein skin test (C-TST) was higher than that of the tuberculin skin test (TST), but the difference was not statistically significant ( χ 2=0.65, P =0.42); among close contacts, the detection rate of TST was higher than that of C-TST (15.1%,10.1%; χ 2=5.23, P <0.05). Conclusion From 2020 to 2024, the annual average incidence of pulmonary tuberculosis among college students in Yangzhou showed an overall fluctuating downward trend, with differences in TB infection screening methods and gender.

Ischemic stroke (IS) is a globally life-threatening disease. Presently, few therapeutic medicines are available for treating IS, and rt-PA is the only drug approved by the US Food and Drug Administration (FDA) in the US. In fact, many agents showing excellent neuroprotection but no blood flow-improving activity in animals have not achieved ideal clinical efficacy, while thrombolytic drugs only improving blood flow without neuroprotection have limited their wider application. To address these challenges and meet the huge unmet clinical need, we have designed and identified a novel compound AAPB with dual effects of neuroprotection and cerebral blood flow improvement. AAPB significantly reduced cerebral infarction and neural function deficit in tMCAO rats, pMCAO rats, and IS rhesus monkeys, as well as displayed exceptional safety profiles and excellent pharmacokinetic properties in rats and dogs. AAPB has now entered phase I of clinical trials fighting IS in China.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective To investigate the effect of moxibustion on different phenotypic expression of macrophages in rheumatoid arthritis(RA).Methods Thirty rats were randomly divided into the blank group,the model group and the moxibustion group,with 10 rats in each group.Rats in the model group and the moxibustion group were injected with complete Freund's adjuvant(CFA)into right foot pad to prepare RA model.The moxibustion group received moxibustion treatment.The blank group was injected with the same amount of normal saline.The thickness of foot pad was measure and arthritis index score was performed.Pathological changes of joints were observed by hematoxylin eosin staining(HE),and the expressions of CD80,CD163 and SPP1 in macrophages of synovial tissue were detected by immunofluorescence.Results Compared with the blank group,arthritis index score and thickness of foot pad were increased in the model group and the moxibustion group(P＜0.05).After moxibustion treatment,compared with the model group,the score of arthritis index and thickness of foot pad were decreased in the moxibustion group(P＜0.05).HE staining showed joint space narrowing,subchondral bone destruction and inflammatory cell infiltration in the model group.The degree of joint space narrowing,subchondral bone destruction and inflammatory cell infiltration were less in the moxibustion group than those in the model group.Compared with the blank group,the scores of synovial tissue hyperplasia,synovial fibrous tissue hyperplasia and inflammatory cell infiltration increased in the model group.Compared with the model group,scores of synovial tissue hyperplasia,fibrous tissue hyperplasia and inflammatory cell infiltration decreased in the moxibustion group(P＜0.05).Results of immunofluorescence detection showed that compared with the blank group,the expressions of CD80 and SPP1 in synovial tissue were up-regulated in the model group,while the expression of CD163 was down-regulated.Compared with the model group,the expressions of CD80 and SPP1 were down-regulated,and the expression of CD163 was up-regulated in the moxibustion group(P＜0.05).Conclusion Moxibustion can regulate the expression of different phenotypes of macrophages and reduce synovial inflammation of RA.The mechanism may be related to regulating the expression of different phenotypes of macrophages.

Background Existing studies have confirmed that fine particulate matter (PM_2.5)is one of the important factors inducing pulmonary fibrosis. Pulmonary fibrosis is the terminal stage of a major category of lung diseases characterized by the destruction of tissue structure, and eventually leading lung ventilation and ventilation dysfunction. No effective pulmonary fibrosis treatment is available yet. Objective To investigate the protective effect of salidroside on pulmonary fibrosis induced by the exposure of PM_2.5 and its molecular mechanism. Methods Seventy 7-week-old male C57BL/6 mice were randomly divided into four groups: control group (intratracheal instillation of normal saline + saline by gavage, n=25), Sal group (intratracheal instillation of normal saline + Sal 60 mg·kg⁻¹ by gavage, n=10), PM_2.5 group (intratracheal instillation of PM_2.5 5 mg·kg⁻¹ + saline by gavage, n=10), and Sal + PM_2.5 group (intratracheal instillation of PM_2.5 5 mg·kg⁻¹ +Sal 60 mg·kg⁻¹ by gavage, n=10). The mice were administered by gavage once daily, intratracheal instillation once every 3 d, and every 3 d constituted an experimental cycle. At the end of the 26-30th cycles, 3 mice in the control group and 3 mice in the PM_2.5 group were randomly sacrificed, and the lung tissues were collected for Masson staining to verify whether the pulmonary fibrosis model was successfully established. After 30 cycles, the model was successfully constructed. After 1 week of continuous observation, the mice were sacrificed, and the blood and lung tissues of the mice were collected to make lung tissue sections. Assay kits were correspondingly employed to detect oxidative stress indicators such as serum malondialdehyde (MDA) and superoxide dismutase (SOD). Western blotting was used to detect the expression of fibrosis-related proteins (Collagen-III, α-SMA), mitochondrial dynamics-related proteins (MFN1, Drp1), and mitophagy-related proteins (PINK1, Parkin, and LC3). Results Compared with the control group, the weight gain rate of the PM_2.5 group was slowed down (P<0.05), which was alleviated by the Sal intervention (P<0.05). The lung coefficient increased after the PM_2.5 exposure (P<0.05), which was alleviated by Sal intervention. Compared with the control group, the PM_2.5 group showed severe alveolar structure damage, inflammatory cell infiltration, and blue collagen deposition, and significantly increased the lung injury score, collagen volume fraction (CVF), Szapiel score, and Ashcroft score (P<0.05), as well as serum oxidative stress levels (P<0.05). The protein expression levels of Collagen-III, α-SMA, Drp1, PINK1, Parkin, and LC3 II/I were increased (P<0.05), and the expression of MFN1 was decreased (P<0.05). Compared with the PM_2.5 group, the Sal intervention alleviated lung injury, reduced inflammatory cell infiltration and collagen deposition, showing decreased lung injury score, CVF, Szapiel score, and Ashcroft score (P<0.05), and decreased serum oxidative stress levels (P<0.05); the protein expression levels of Collagen-III, α-SMA, PINK1, Parkin, and LC3 II/I were decreased (P<0.05), the expression level of Drp1 was decreased, and the expression level of MFN1 was increased. Conclusion In the process of pulmonary fibrosis induced by PM_2.5 exposure in mice, Sal may affect mitochondrial autophagy through PINK1/Parkin pathway and play a protective role. The specific mechanism needs to be further verified.

Objective To explore the relationships of vitamin D and oxidized low-density lipoprotein(ox-LDL)with infertility in patients with polycystic ovary syndrome(PCOS)based on restricted cubic spline models.Methods A total of 150 PCOS patients were selected as the study subjects and followed up for at least 1 year.They were divided into infertile group and non-infertile group according to whether they were infertile.A Logistic regression model was used to analyze the influencing factors of infertility in PCOS patients.Furthermore,the relationships of 1,25-dihydroxyvitamin D3[1,25-(OH)2D3]and ox-LDL with infertility in PCOS patients,as well as their interactive effects on infertility in PCOS patients were analyzed.A restricted cubic spline model was used to analyze the non-linear relationships between 1,25-(OH)2D3,ox-LDL,and infertility in PCOS patients.Results Among 150 PCOS patients,78 were not pregnant,resulting in an infertility rate of 52.00％(78/150).Multivariate Logistic regression analysis showed that the severity of PCOS,body mass index,age,1,25-(OH)2D3,and ox-LDL were all independent influencing factors for infertility in PCOS patients(P＜0.05).After adjusting for confounding factors,1,25-(OH)2D3 and ox-LDL were still associated with the risk of in-fertility in PCOS patients(P＜0.05).Restricted cubic spline model analysis revealed non-linear rela-tionships between 1,25-(OH)2D3,ox-LDL,and the risk of infertility in PCOS patients(P＜0.05).When the serum 1,25-(OH)2D3 level was＜35.70 nmol/L,it was negatively correlated with the risk of infertility in PCOS patients(P＜0.05).When the serum ox-LDL level was ≥381.00 μg/L,it was positively correlated with the risk of infertility in PCOS patients(P＜0.05).Interactive effect analysis showed that 1,25-(OH)2D3 and ox-LDL had antagonistic effects on infertility in PCOS pa-tients(P＜0.05).Conclusion Decreased serum 1,25-(OH)2D3 levels and increased ox-LDL levels in PCOS patients can significantly increase the risk of infertility.Moreover,there is a non-lin-ear dose-response relationship and an antagonistic interactive effect between them,suggesting that regulating vitamin D and oxidative stress levels may be an important strategy for improving the fertili-ty outcomes of PCOS patients.

ObjectiveTo study the relationship between qi stagnation constitution and suboptimal health status (SHS) or lifestyle.MethodsFrom 2012 to 2013, we conducted a cross-sectional survey of 24 159 Chinese individuals aged 12–80 years. The qi stagnation constitution was assessed using the Constitution in Chinese Medicine Questionnaire. Health status was evaluated through medical records and the Subhealth Measurement Scale V1.0 (SHMS V1.0). Health-promoting lifestyles were measured using the Health-Promoting Lifestyle Profile II (HPLP-II).ResultsOf the 24 159 participants, 16.1% and 15.2% were classified as “always” and “sometimes” having the qi stagnation constitution, respectively. Those classified as “rarely” having the qi stagnation constitution scored higher on both the HPLP-II and SHMS V1.0. The participants classified as “always” having the qi stagnation constitution showed a significant association with SHS or disease compared to other imbalanced constitutions. Those in the “always” category were approximately 21 times more likely to be classified as having SHS (odds ratio [OR]: 21.17, 95% confidence interval [CI]: 15.74–28.45), whereas those in the “sometimes” category were approximately six times more likely (OR: 5.89, 95% CI: 5.04–6.90). Accordingly, the qi stagnation constitution score was significantly associated with the diagnosis of SHS, with an area under the curve of 0.77 (P .001). A score of 18.75 yielded the highest Youden Index (0.407), with a sensitivity of 60.5% and a specificity of 80.3%. Significant associations were observed between health-promoting lifestyles and qi stagnation constitution severity in an ordinal regression analysis (P .001). Protective factors included stress management (OR: 1.59), self-actualization (OR: 1.57), and exercise (OR: 1.36). In contrast, poorer interpersonal relationships (OR: 0.79), greater health responsibilities (OR: 0.86), and poorer nutrition (OR: 0.91) were associated with increased severity.ConclusionModulating the qi stagnation constitution through lifestyle interventions may help prevent the progression of SHS to disease, which aligns with core preventive principles in traditional Chinese medicine.

Objective To evaluate the safety and effectiveness of different doses of epidural oxycodone injection for traction reaction during cesarean sections to determine the optimal dose.Methods Totally 119 cases of parturients who underwent cesarean sections from October 2023 to May 2024 were selected and randomly divided into groups A,B,C and D.All four groups of lying-in women received epidural injection after the umbilical cord was cut.Groups A,B and C were given oxycodone 3 mg,5 mg and 7 mg respectively,and group D was given an equal amount of normal saline.The primary outcomes were documentation of maternal vital signs and traction reaction during the surgery.Secondary outcomes included patient-controlled intravenous analgesia(PCIA)times within 48 hours and documentation of any postoperative adverse events within 24 hours.Results The comparison of in-tra?operative vital signs among the four groups of patients revealed no statistically significant differences.In groups A,B and C the incidence of traction reactions was significantly lower at 20％,17.2％and 3.3％,respectively,compared to group D at 53.3％,showing statistically significant differences(P<0.05).Additionally,the inci?dence of traction reaction in group C was significantly lower than in group A(P<0.05).Groups A,B and C pro?duced significantly better results than group D in terms of the duration of anesthesia.PCIA presses were substan?tially less in groups A and C than in group D(P<0.05),and group C had a significantly higher total incidence of adverse events than group A and group D(P<0.05).Conclusions Epidural injection of 3 mg,5 mg and 7 mg oxycodone has been proved to significantly reduce traction reaction during cesarean sections while minimally im?pacting intraoperative vital signs.This intervention has the potential to extend the duration of anesthesia,decrease the frequency of PCIA presses.Among these,7 mg is the most effective but has the highest incidence of adverse effects,requiring carefully post?operative monitoring.
