AIM:To analyze differential proteins associated with the pathogenesis of dry eye(DE)using bioinformatics methods, in order to reveal their potential molecular mechanisms.METHODS: Articles published in PubMed and EMBASE databases from the inception of the database to August 31, 2023, that used proteomic methods to detect protein expression in clinical samples of dry eye were searched. Differential proteins were selected and further analyzed using the STRING database and Cytoscape software for hub gene screening and module analysis. Protein-protein interaction(PPI)analysis, gene ontology(GO)functional annotation, and Kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analysis were performed.RESULTS: A total of 21 articles were included, identifying 74 differentially expressed proteins. The most frequently occurring differential proteins were calgranulin A(SA1008), lipocalin-1(LCN1), lysozyme C(LYZ), mammaglobin-B(SCGB2A1), proline-rich protein 4(PRR4), transferrin(TF), and calgranulinB(S100A9). The top 10 hub genes were serum albumin(ALB), tumor necrosis factor(TNF), interleukin 6(IL6), IL1B, IL8, matrix metalloproteinase 9(MMP9), alpha-1-antitrypsin(SERPINA1), IL10, complement component 3(C3), and lactotransferrin(LTF). Module analysis suggested MMP9 and PRR4 as seed genes. KEGG analysis showed that differential proteins were mainly enriched in the IL17 signaling pathway(61.9%).CONCLUSION: The results reveal potential molecular targets and pathways for DE and confirm the association between the pathogenesis of DE and inflammation. Further in-depth research is needed to confirm the significance of these biomarkers in clinical practice.

Objective: To investigate the efficacy and safety of intelligent temperature-pressure-controlled flexible ureteroscopy combined with negative-pressure suction sheath lithotripsy in the treatment of upper urinary tract stones ≤2.5 cm. Methods: The clinical data of 225 patients with ≤2.5 cm upper urinary tract stones treated with this surgical method in our department during Aug. 2023 and Jul. 2024 were retrospectively analyzed. The patients were divided into the dual-control group (n=36) and conventional group (n=189) according to whether or not the intelligent temperature and pressure control device was used during operation. In the dual-control group,the intraoperative temperature and pressure in the renal pelvis were monitored and controlled in real time by the temperature and pressure sensors distributed at the end of the ureteral soft lens. The perioperative parameters,stone-removal rate,complication rate and renal function were compared between the two groups. Results: All operations were successfully completed in both groups. The postoperative procalcitonin (PCT) level [(22.75±5.85) ng/L vs. (29.08±6.60) ng/L,P=0.001],difference in the white blood cell (WBC) level [(0.24±2.12)×10
cells/L vs. (1.19±2.17)×10
cells/L,P=0.016],incidence of fever (2.8% vs. 16.9%,P=0.028) and overall complication rate (5.6% vs. 19.6%,P=0.042) were significantly lower in the dual-control group than in the conventional group,while the stone-clearance rate was slightly higher (88.9% vs. 82.5%,P=0.346),with no significant difference. Conclusion: For upper urinary tract stones ≤2.5 cm,intelligent temperature-pressure-controlled ureteroscopy combined with negative-pressure suction sheath lithotripsy has a satisfactory stone-removal rate and a low rate of complications,which is worthy of clinical promotion.

To implement the instructions and directives of General Secretary Xi Jinping on important documents related to traditional Chinese medicine (TCM), adhere to the equal emphasis on TCM and Western medicine, and promote mutual complementarity, win-win cooperation, and coordinated development between TCM and Western medicine, the China Association of Chinese Medicine has organized seminars on the clinical dominant diseases of TCM in multiple professional fields, achieving a series of results. The aim is to implement the research on dominant diseases of TCM described in the Law of the People's Republic of China on Traditional Chinese Medicine and the Opinions of the Central Committee of the Communist Party of China and the State Council on Promoting the Inheritance, Innovation and Development of Traditional Chinese Medicine, thus serving the construction of advantageous specialties, clinical talent cultivation, national scientific and technological layout, and academic innovation leadership. In the field of otolaryngology, the China Association of Chinese Medicine and many Chinese and Western medicine experts across the country have conducted multiple in-depth discussions and research. At the 10th Clinical Dominant Disease Series Youth Salon, they have elaborated and demonstrated the basic and specific suggestions and consensus on the clinical advantages of TCM and integrated TCM and Western medicine in the treatment of allergic rhinitis (AR), making great progress. However, there is still a lack of detailed research paths. Under the guidance of the China Association of Chinese Medicine and based on the TCM Dominant Disease Series Salon for AR, this study analyzed the difficulties encountered in AR diagnosis and treatment according to the occurrence and development law of AR. Based on the advantages and characteristics of AR diagnosis and treatment by TCM and integrated TCM and Western medicine, it explored the research paradigm and technological layout points of AR and put forward suggestions. The layout involved four aspects: Optimization of the AR diagnosis and treatment system, prevention and control of comorbidities, management of chronic diseases, and a platform for TCM inheritance. Additionally, suggestions for layout and research directions, expected goals and values, and priority levels for funding were proposed. The study is expected to provide a theoretical basis and development ideas for the future prevention and treatment of AR with TCM and integrated TCM and Western medicine and promote the high-quality development of TCM.

OBJECTIVE:
To investigate the effectiveness of endoscopic-assisted median nerve decompression with one-stage extensor indicis proprius (EIP) tendon transfer for reconstruction of thumb abduction in patients with severe carpal tunnel syndrome (CTS).
METHODS:
The clinical data of 12 patients with severe CTS who met the selection criteria between December 2019 and December 2024 were retrospectively analyzed. There were 2 males and 10 females with an average age of 55.4 years ranging from 35 to 67 years. The symptom duration of CTS was 12-120 months (mean, 48.7 months) and the thenar muscle atrophy duration was 6-48 months (mean, 13.4 months). The median nerve was released with the help of endoscope, and the EIP tendon was transferred to reconstruct the abduction function of the thumb. The operation time and complications were recorded. Two-point discrimination, palmar abduction angle of the thumb, radial abduction angle of the thumb, and pinch force of the thumb were measured and compared before operation and at last follow-up, and the effectiveness was evaluated by Kapandji score and Disabilities of the Arm, Shoulder and Hand (DASH) score. The satisfaction of the operation was evaluated at last follow-up.
RESULTS:
All surgeries were successfully completed with a mean operation time of 54 minutes (range, 45-68 minutes). All patients were followed up 6-50 months, with an average of 15.3 months. There was no complications such as wound infection, scar pain of wrist, or tendon rupture of transposition, and there were 3 cases of mild limitation of finger extension in the donor site of index finger. At last follow-up, two-point discrimination, palmar abduction angle of the thumb, radial abduction angle of the thumb, Kapandji score, and DASH score were significantly better than those before operation ( P<0.05), but there was no significant difference in thumb pinch force between pre- and post-operation ( P>0.05). The evaluation of surgical satisfaction showed that 7 cases were very satisfied and 5 cases were satisfied.
CONCLUSION
The combination of endoscopic-assisted median nerve decompression and one-stage EIP tendon transfer effectively improves hand function and quality of life in patients with severe CTS by restoring thumb abduction and alleviating neurological symptoms.

The cardioprotective effects of histone deacetylase (HDAC) inhibitors (HDIs) are at odds with the deleterious effects of HDAC depletion. Here, we use HDAC3 as a prototype HDAC to address this contradiction. We show that adult-onset cardiac-specific depletion of HDAC3 in mice causes cardiac hypertrophy and contractile dysfunction on a high-fat diet (HFD), excluding developmental disruption as a major reason for the contradiction. Genetically abolishing HDAC3 enzymatic activity without affecting its protein level does not cause cardiac dysfunction on HFD. HDAC3 depletion causes robust downregulation of lipid oxidation/bioenergetic genes and upregulation of antioxidant/anti-apoptotic genes. In contrast, HDAC3 enzyme activity abolishment causes much milder changes in far fewer genes. The abnormal gene expression is cardiomyocyte-autonomous and can be rescued by an enzyme-dead HDAC3 mutant but not by an HDAC3 mutant (Δ33-70) that lacks interaction with the nuclear-envelope protein lamina-associated polypeptide 2β (LAP2β). Tethering LAP2β to the HDAC3 Δ33-70 mutant restored its ability to rescue gene expression. Finally, HDAC3 depletion, not loss of HDAC3 enzymatic activity, exacerbates cardiac contractile functions upon aortic constriction. These results suggest that the cardiac function of HDAC3 in adults is not attributable to its enzyme activity, which has implications for understanding the cardioprotective effects of HDIs.

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.

Osteoarthritis (OA) is a chronic degenerative joint disease whose main characteristic is the destruction of articular cartilage, causing pain and disability in patients and seriously affecting their quality of life. OA can be induced by a variety of causes, and pathological changes in articular cartilage are considered to be one of the key driving factors for the occurrence of OA. High mobility group box-1 protein (HMGB1), as a non-histone protein in eukaryotic cells, can participate in regulating the inflammation and apoptosis process of OA chondrocytes, thus leading to the occurrence of OA. This article reviews the research on the mechanism of HMGB1 in OA chondrocytes, with a view to providing new ideas for the clinical prevention and treatment of OA.

Objective To investigate the efficacy of combined use of apigenin and resveratrol in the treatment of non-alcoholic fatty liver disease (NAFLD). Methods Fifty male C57BL/6 mice were randomly divided into a normal group (n=10) and a model group (n=40). The NAFLD model was established in the model group using carbon tetrachloride (CCl4) and a high-fat diet. After successful modeling, the model group was further divided into a model group, an apigenin group, a resveratrol group, and an apigenin and resveratrol combined group (combined administration group), with 10 mice in each group. The mice were administered once daily for four consecutive weeks. At the end of the administration, the mice in each group were weighed, the eyeballs were taken for blood samples, and the necks were dissected and sacrificed. The livers were dissected and weighed, and the liver index was calculated. The automatic biochemical analyzer was used to detect the serum biochemical indicators of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglycerides (TG), and total cholesterol (TC) levels in mice. The ELISA method was used to detect the contents of superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT) and glutathione peroxidase (GSH-Px) in mouse 10% liver tissue homogenate. HE staining was used to observe the pathological morphology of liver tissue in mice. Results Compared with the normal group, the liver index and serum biochemical ALT, AST, TG, TC levels in the model group were significantly increased (P<0.01), and the liver homogenate MDA was significantly increased (P<0.01), while the levels of SOD, CAT, GSH- Px were decreased significantly (P<0.01). There were a large number of fatty vacuoles and hepatic cord disorders in the liver tissue. Compared with the apigenin group and the resveratrol group, the liver index, and serum biochemical ALT, AST, TG and TC levels in the combined administration group decreased (P<0.05), and the liver homogenate MDA level decreased (P<0.05), and the levels of SOD, CAT and GSH-Px were increased (P<0.05). The number of fatty vacuoles in liver tissues were reduced, hepatic cord disorders were improved. Conclusions The combined administration of apigenin and resveratrol has a protective effect on NAFLD model mice, possibly through the reduction of hepatic enzymes and blood lipid levels, as well as enhanced antioxidant activity. The combination treatment shows better efficacy compared to the apigenin and resveratrol groups.
