Objective To assess the clinical value of a novel surgical technique—Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in the resection of anterior mediastinal masses. Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.

To address the problem of data silos in dental specialties caused by equipment heterogeneity, this study developed an Intelligent Internet of Things (IoT)-enabled dental chair platform (hereinafter referred to as the intelligent platform) based on the concept of medical-engineering integration. The platform adopts a three-tier chair-domain interconnection architecture: the bottom tier integrates multi-source sensors and standardized interfaces for automated data acquisition and linkage with hospital information systems; the middle tier provides clinic-level management and remote teaching collaboration; and the top tier employs a blockchain-based secure cloud database for resource allocation and data management. Clinical validation at The Affiliated Stomatological Hospital of Nanjing Medical University demonstrated that, compared with a control group from the same period in 2023, the trial group achieved a 38.0% increase in average daily patient visits (80.6±6.8 vs. 58.4±5.2, t=15.16, P<0.001), a 24.6% reduction in average treatment time [(36.1±6.3) min vs. (47.9±8.5) min, t=7.72, P<0.001], a 39.2% reduction in waiting time [23.3 (16.5, 30.1) min vs. 38.3 (28.3, 48.3) min, U=32.00, P<0.001], a 30.4% reduction in equipment idle rate [8.7% (5.1%, 12.3%) vs. 12.5% (7.4%, 17.6%), U=251.00, P=0.003], and an increase in patient satisfaction from 88.2% (1 519/1 723) to 94.3% (2 186/2 318) ( t=7.26, P<0.001). User research confirmed that the functions most favored by clinicians and patients were "dental chair parameter updating and clinical data integration" [74.7% (80/107)] and "chairside display of diagnostic images" [76.8% (119/155)], respectively. Looking forward, the intelligent platform has the potential to integrate artificial intelligence-assisted diagnosis and 5G-enabled multicenter collaboration to further expand its clinical applications and accelerate the digital transformation of dental healthcare.

Objective To investigate the role and potential mechanisms of tumor necrosis factor alpha-inducible protein 8-like molecule 1(TNFAIP8L1)in acute liver injury in mice.Methods The second generation of C57BL/6J male wild-type(WT)mice and the C57BL/6J female TNFAIP8L1+/-mice and WT mice were selected to further self-breed the third generation of male TNFAIP8L1-/-mice and the third generation of WT male mice.Five normal third-generation male WT mice and five normal third-generation male TNFAIP8L1-/-mice were selected.The serum alanine aminotransferase(ALT)levels of the two types of normal mice were measured and compared.The infiltration of inflammatory cells and cell necrosis in the liver tissues of the two types of normal mice were observed after hematoxylin & eosin(HE)staining.Flow cytometry was used to detect the percentages of neutrophils(Neu),eosinophils(EOS),dendritic cells(DC),bone marrow-derived macrophages(BMDMs),and bone marrow-derived mononuclear cell(BMNCs)in the liver myeloid cell subsets of the two types of normal mice.Another 5 third-generation male WT mice and 4 third-generation male TNFAIP8L1-/-mice were selected to induce acute liver injury mouse models using lipopolysaccharide(LPS)/D-galactosamine(D-Gal).After 24 hours,the serum ALT levels of the two types of acute liver injury mice were detected and compared,the infiltration of inflammatory cells and cell necrosis in the liver tissues of the two types of acute liver injury mice were observed,and the percentages of Neu,EOS,DC,BMDMs and BMNCs in the liver myeloid cell subsets of the two types of acute liver injury mice were measured by using the above methods.Results There was no significant difference in the percentages of Neu,EOS,DC,BMDMs and BMNCs,and serum ALT levels in the livermyeloid cell subsets of normal WT mice and TNFAIP8L1-/-mice(P＞0.05).HE staining results of liver tissues in normal WT mice and TNFAIP8L1/mice showed that hepatic lobules were structurally complete and clear,hepatocytes were morphologically normal and arranged neatly,and there was no obvious inflammatory cell infiltration or cell necrosis.Twenty-four hours after acute liver injury,the percentages of Neu and BMNCs in the liver myeloid cell subsets and the serum ALT levels in the liver tissues of TNFAIP8L1-/-mice were significantly higher than those of WT mice(P＜0.05);there was no significant difference in the percentages of EOS,DC and BMDMs in the liver myeloid cell subsets of mice between the two groups(P＞0.05).In the liver tissues of WT mice with acute liver injury,hepatic lobules were structurally blurred,hepatocytes were swollen with scattered vacuolated steatosis,and a small amount of inflammatory cells were infiltrated.In the liver tissues of TNFAIP8L1/mice with acute liver injury,hepatic lobules were structurally non-existent,and hepatocytes were severely damaged and extensively necrotic,with a large amount of inflammatory cell infiltration.Conclusion The deficiency of the TNFAIP8L1 gene in mice does not affect the development of liver myeloid cells and the homeostasis of the liver.TNFAIP8L1 plays an inhibitory role in the occurrence and development of acute liver injury.TNFAIP8L1 gene deficiency aggravates LPS/D-Gal-induced acute liver injury,possibly by increasing Neu and BMNCs infiltration and recruiting other types of immune cells to infiltrate liver tissues,thereby exacerbating liver cell necrosis.

Objective:To explore the incidence rates, clinical features, risk factors and its impacts on survival of central nervous system complications (CNSC) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:From June 2011 to October 2018, 237 consecutive patients undergoing allo-HSCT were retrospectively analyzed.Results:The incidence of CNSC was 10.5%(25/237) and the median time 82(-4 - 810) days post-transplantation. The most common instances of CNSC were drug-associated encephalopathy (n=6), CNS infection (n=5), unexplained convulsions (n=4), metabolic encephalopathy (n=3), immune-related encephalopathy (n=3), primary central relapse (n=3) and cerebrovasculopathy (n=1). The most common clinical symptom was epileptic seizure (n=11). CsA-related encephalopathy was manifested mainly as posterior reversible encephalopathy syndrome on brain MRI. Metabolic encephalopathy is mostly demyelination. Most hippocampal lesions were caused by immune-related encephalopathy or CNS infection. Analysis of risk factors indicated that umbilical cord blood transplantation, HLA incompatible transplantation and delayed platelet implantation were high risk factors for post-transplantation occurrence of CNSC. Survival analysis suggested that non-relapse mortality rate (42.9%, 9/21) in group with CNSC of malignant hemoblastosis was higher than that in group without CNSC (15.3%, 27/176) and inter-group difference was statistically significant ( χ2=9.511, P=0.005). The 1/3-year OS rates in group with CNSC were lower than those in group without CNSC (56.6% vs 77.8%; 37.1% vs 65.7%). And the difference was statistically significant ( P=0.022). Conclusions:With a complex etiology, CNSC is one of serious complications after allo-HSCT and it significantly reduces the overall survival rate of patients. Umbilical cord blood transplantation, HLA incompatible transplantation and delayed platelet implantation are high-risk groups for CNSC.

Objective To analyze the epidemiological features and trends of glenoid fractures from 2003 through 2012 in the Third Affiliated Hospital to Hebei Medical University.Methods The clinical data were collected of the patients with glenoid fracture who had been treated between January 2003 and December 2012 in our hospital.The patients' gender,age and fracture type of Ideberg classification were documented.The data from January 2003 to December 2007 were assigned into group A and those from January 2008 to December 2012 into group B.The 2 groups were compared to find out the general epidemiological characteristics and trends in the recent 10 years.Results A total of 225 patients with glenoid fracture were collected,including 176 males and 49 females.The total male/female ratio was 3.59∶ 1.The glenoid fractures predominated in an age range of 31 to 40 years (23.56％).According to Ideberg classification,there were 35 cases (15.56％) of type Ⅰ,58 ones (25.78％) of type Ⅱ,64 ones (28.44％) of type Ⅲ,21 ones (9.33％) of type Ⅳ,30 ones(13.33％) of type Ⅴ and 17 ones(7.56％) of type Ⅵ.The male/female ratio was 5.29∶1 in group A of 107 patients and 2.69∶1 in group B of 118 patients.The mean age of group A was 40.2 ± 16.0 years and that of group B 47.5 ± 14.8 years.The differences in male/female ratio,mean age and distribution of age were statistically significant between the 2 groups (P ＜ O.05).The fractures predominated in an age range of 31 to 40 years (28.97％) in group A and in the age group of 51 to 60 years (27.12％) in group B.The most frequent fracture type was type Ⅲ in both groups,accounting for 29.91％ and 27.12％ respectively.There was no significant difference between the 2 groups in distribution of Ideberg classification (P ＞ 0.05).Conclusions The peak age of glenoid fractures was from 31 to 40 years.There was an increasing trend in the mean age.There were more male patients than female ones.The high-frequency type was Ideberg type Ⅲ.

of NB4 cells at S phase was lower than those in control group (P <0.05),and the number of NB4 cells at G1 phase was increased (P <0.05).The expression levels of Bcl-2 in ICA groups were significantly lower than that in control group (P < 0.05 ), while the expression levels of Bax were higher than that in control group (P < 0.05 ). Conclusion ICA can induce the apoptosis of NB4 cells via inhibiting the expression level of Bcl-2 and up-regulating the expression level of Bax.
