BACKGROUND: Periodontitis is characterized by alveolar bone resorption, aggravated by osteoblast dysfunction, and associated with intracellular oxidative stress linked to the nuclear factor erythroid 2-related factor 2 (NRF2) level. We evaluated the molecular mechanism of periodontitis onset and development and the role of NRF2 in osteogenic differentiation. METHODS: Primary murine mandibular osteoblasts were extracted and exposed to Porphyromonas gingivalis lipopolysaccharide (Pg-LPS) or other stimuli. Reactive oxygen species (ROS) and 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolylcarbocyanine iodide (JC-1) staining were used to detect intracellular oxidative stress. Alkaline phosphatase staining and alizarin red S staining were used to detect the osteogenic differentiation of osteoblasts. Immunofluorescence and western blotting were used to determine the changes in the mitogen-activated protein kinase (MAPK) pathway and related molecule activities. Immunofluorescence colocalization and co-immunoprecipitation were performed to examine the nuclear translocation of NRF2 and its interaction with dual-specific phosphatase 1 (DUSP1) in cells. RESULTS: Ligated tissue samples showed higher alveolar bone resorption rate and lower NRF2 level than healthy periodontal tissue samples. Pg-LPS increased intracellular oxidative stress levels and inhibited osteogenic differentiation, whereas changes in NRF2 expression were correlated with changes in the oxidative stress and osteogenesis rate. NRF2 promoted the dephosphorylation of the MAPK pathway by nuclear translocation and the upregulation of DUSP1 expression, thus enhancing the osteogenic differentiation capacity of mandibular osteoblasts. The interaction between NRF2 and DUSP1 was observed. CONCLUSIONS: NRF2 and its nuclear translocation can regulate the osteogenic differentiation of mandibular osteoblasts under Pg-LPS conditions by interacting with DUSP1 in a process linked to the MAPK pathway. These findings form the basis of periodontitis treatment.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective:To investigate the management options for loop plate cutting of the tibial cortex during reconstruction of the anterior cruciate ligament (ACL) by the all-inside technique.Methods:From January 2022 to December 2024, a total of 13 patients with ACL injury who underwent all-inside reconstruction with tibial lateral loop plate cutting of the cortex and immediate revision for ACL injuries at Department of Sports Medicine, the First Affiliated Hospital of University of Science and Technology of China were retrospectively analyzed (cut group). There were 5 males and 8 females with an average age of 28.7±9.1 years (range, 17-39 years). During the revision, a transverse tunnel was drilled at the distal end of the tibial tunnel, and the loop plate was fixed to the lateral tibial cortex through the transverse tunnel. Matched by gender, age, and side, the patients who underwent ACL reconstruction with all-inside loop steel without cutting the tibial cortex during the same period (the uncut group) were selected as the control group at a ratio of 1∶2, including 10 males and 16 females, aged 29.1±9.3 years (range, 17-39 years). The visual analogue scale (VAS), Tegner score, International Knee Documentation Committee (IKDC) and Lysholm score for knee pain before and after surgery were compared between the two groups, and bone tunnel enlargement was assessed using the Peyrache grading scale.Results:All patients were successfully operated and followed up for 13.1±2.5 months and 13.3±2.6 months, respectively. The Lysholm scores of the cutting group before surgery, 6 months after surgery, and 1 year after surgery were 35.44±15.69, 75.21±16.77, and 93.47±18.56 respectively, while those of the uncut group were 37.81±17.33, 71.45±15.82, and 91.05±19.54. The Lysholm scores of both groups 6 months and 1 year after surgery were higher than those before surgery, and the Lysholm scores 1 year after surgery were higher than those 6 months after surgery, with statistically significant differences ( P<0.05). There were no statistically significant differences in the Lysholm scores between the two groups before and after surgery ( P>0.05). The IKDC scores of the cutting group before surgery, 6 months after surgery, and 1 year after surgery were 39.12±14.28, 69.52±15.36, and 84.24±17.91 respectively, while those of the uncut group were 37.46±11.55, 72.81±17.73, and 87.62±18.52. The IKDC scores of both groups 6 months and 1 year after surgery were higher than those before surgery, and the IKDC scores 1 year after surgery were higher than those 6 months after surgery, with statistically significant differences ( P<0.05). There were no statistically significant differences in the IKDC scores between the two groups before and after surgery ( P>0.05). The Tegner scores of the cutting group before surgery, 6 months after surgery, and 1 year after surgery were 1.61±1.11, 3.59±1.66, and 5.59±1.79 respectively, while those of the non-cutting group were 1.57±1.05, 3.47±1.51, and 5.41±1.63. The Tegner scores of both groups 6 months and 1 year after surgery were higher than those before surgery, and the Tegner scores 1 year after surgery were higher than those 6 months after surgery, with statistically significant differences ( P<0.05). There were no statistically significant differences in the Tegner scores between the two groups before and after surgery ( P>0.05). According to Peyrache's grading criteria, 7 cases in the cutting group had femoral side bone tunnel enlargement and 8 cases had tibial side bone tunnel enlargement; 12 cases in the non-cutting group had femoral side bone tunnel enlargement and 15 cases had tibial side bone tunnel enlargement, with no statistically significant differences (χ 2=0.205, P=0.650; χ 2=0.053, P=0.818). At the last follow-up, there were 2 cases of Lachman grade I in the cutting group and 3 cases in the non-cutting group, 1 case of joint stiffness in the cutting group and 2 cases in the non-cutting group. None of the patients in the two groups had vascular nerve injury, deep vein thrombosis, or intra-articular infection. Conclusion:The method of drilling a transverse tunnel at the distal end of the outer opening of the tibial tunnel and fixing the loop plate to the lateral tibial cortex through the transverse tunnel, along with cutting the tibial cortex, can improve the knee joint function.

Objective:To quantitatively evaluate the effects of left bundle branch block（LBBB）on left ventricular structure，function and myocardial perfusion using left ventricular pressure-strain loop and single photon emission computed tomography（SPECT），and to investigate the relationship between myocardial work，myocardial perfusion and pathological changes of left ventricular remodeling in left bundle branch block induced cardiomyopathy（LBBB-CM）.Methods:Fourteen male beagle dogs were selected，and the main trunk of the left bundle branch was ablated to create an LBBB dog model. Electrocardiogram（ECG），transesophageal echocardiography and arterial blood pressure data of LBBB dogs were collected before and 12 months after the ablation of left bundle branch trunk. Global and segmental myocardial work parameters were obtained by left ventricular pressure-strain loop. The differences of above parameters between baseline and 12 months after the ablation of left bundle branch were compared. SPECT was performed in LBBB dogs 12 months after the creation of LBBB. The hearts were harvested for anatomy observation and histopathological analysis in LBBB dogs and another 7 male beagle dogs（normal control group）matched by age and weight. The correlation between myocardial perfusion（percentage of regional tracer uptake）and myocardial work parameters，myocardial fibrosis in LBBB dogs were analyzed.Results:Compared with baseline，the left ventricular end-diastolic volume of 12 months after the ablation increased［（20.78 ± 5.32）ml vs（26.71 ± 7.94）ml， P = 0.003］，left ventricular ejection fraction decreased［（59.17 ± 5.67）% vs（47.69 ± 5.45）%， P<0.001］；left ventricular global/segmental longitudinal strain，global/segmental constructive work and global/segmental work efficiency decreased（all P<0.05），left ventricular global/segmental wasted work increased（all P<0.001）. Heterogenous perfusion defect was observed in LBBB dogs by SPECT，compared with lateral wall segments，the percentage of regional tracer uptake of septum was decreased（all P<0.05）. Gross anatomical and myocardial pathological changes were manifested as cardiomegaly，flaky or focal grayish thickening of endocardium，cardiomyocyte degeneration and fibrosis. Compared with normal control group，the collagen fiber volume fraction（CVF）in all segmental endocardium and partial segmental myocardium of LBBB dogs were significantly increased（all P<0.05）. Percentage of regional tracer uptake was positively correlated with segmental myocardial work（SMW）and segmental myocardial efficiency（SWE）（ r s = 0.49，0.31；both P<0.001），and negatively correlated with CVF and segmental wasted work（SWW）（ r s = -0.51，-0.49；both P<0.001）. Conclusions:Isolated LBBB is not benign，which can result in left ventricular remodeling，decreased cardiac constructive function，abnormal myocardial perfusion，endocardial fibrosis and myocardial fibrosis.The parameters of myocardial work assecsed by echocardiograpgy and myocardial perfusion，as non-invasive examination，can to some extent reflect the degree of left ventricular remodeling in LBBB-CM.

Objective:To explore the clinical effect of endoscopic radical thyroidectomy via three-port gasless intermuscular approach.Methods:This is a retrospective cohort study. The data of 148 patients who underwent radical thyroidectomy at the Fourth General Surgery Department of the Second Affiliated Hospital of Harbin Medical University from January to June 2024 were retrospectively analyzed. There were 31 males and 117 females,aging (43.5±9.6) years (range: 21 to 64 years). The surgical method was selected according to the needs and wishes of patients. Among them, 77 cases underwent endoscopic radical thyroidectomy via unilateral three-port gasless intermuscular approach (three-port gasless group),and 71 cases underwent unilateral conventional open radical thyroidectomy(open group). The surgical technique exploration curve of the three-port gasless group was drawn based on the operation time and the number of lymph node dissections,and the technical exploration period and the technical maturity period were divided. The clinical data of the cases in the three-port gasless group and the open group were compared during the technical maturity period. The independent sample t test was used to compare the quantitative data between the two groups, and the χ2 test or Fisher exact probability method was used to compare the categorical data, respectively. Results:According to the technical exploration curve,there were 11 cases in the technical exploration period of the three-port gasless group,and 66 cases in the technical maturity period. In the technical mature period,the injury rate of temporary recurrent laryngeal nerve in the three-port gasless group was 1.5% (1/65),and the number of lymph node dissections was 5.9±3.5(range:0 to 14),which was not statistically significant compared with 4.4% (3/68) and 5.8±3.7(range:0 to 16) in the open group (all P>0.05). In the technical mature period,the operation time of the three-port gasless group was (39.2±6.2)minutes(range:30 to 55 minutes) and the postoperative drainage volume was (57.6±11.8) ml(range:30 to 90 ml),which were lower than those of the open group((67.8±13.9) minutes (range: 30 to 105 minutes) and (82.9±22.4)ml(range:50 to 175 ml)),and the differences were statistically significant ( t=15.303, 8.177, both P>0.05). During the technical maturity period,the postoperative hospital stay in the three-port gasless group was (3.2±0.4)days(range:3 to 4 days), which was not statistically different from that of the open group((3.2±0.4)days(range:3 to 5 days))( P>0.05). The incision satisfaction of patients in the three-port gasless group one month after the operation was higher than that of the control group (100% vs. 62.0%) ( P<0.01). Conclusion:Compared with open surgery,endoscopic radical thyroidectomy via three-port gasless intermuscular approach has certain advantages in terms of operation time, postoperative drainage volume and patient cosmetic satisfaction.

This study intends to establish a colorectal cancer(CRC)organoid model,expand and isolate CRC-reactive tumor-infiltrating lymphocytes(TILs),screen tumor-specific T cell receptors(TCRs)and perform functional verification,in order to provide a technological platform and research foundation for the clinical transformation of individualized adoptive T-cell immunotherapy for colorectal cancer.An organoid model derived from colon cancer patient tissues was constructed using in vitro 3D culture techniques,which then subjected to HE staining and immunohistochemistry for detecting morphological characteristics and representative molecular expression.Subsequently,CRC organoids were co-cultured with TILs for sorting reactive TILs using flow cytometry,and the characteristics of reactive TCR clones was analyzed through single T cell receptor gene cloning technology.Furthermore,the function of TCRs was verified through cytotoxicity experiments.Morphological analysis and representative molecules(CK20 and CDX2)expression indicated that there is high similarity between colorectal cancer organoids and patient tumors.In the in vitro expanded and cultured TILs,colorectal cancer-reactive T cells with upregulated CD137 expression and increased IFN-γ secretion were screened out successfully,among which TCR2-T cells demonstrated superior tumor reactivity and in vitro tumor killing function.In conclusion,a platform for screening and function validation of reactive TCRs based on CRC-Org has been established,providing a technological platform for the translational application of individualized T-cell therapy for colorectal cancer.

Objective To investigate the predictive value of serum Nesfatin-1 and 25-hydroxyvitamin D3[25(OH)D3]levels for the short-term prognosis of status epilepticus(SE)in children.Methods A total of 104 children with SE admitted to the hospital from March 2020 to March 2023 were enrolled in the study,and the clinical data of the children were collected.According to the Glasgow outcome Scale(GOS)score at dis-charge,the children were divided into a good prognosis group(equal to 5 points)and a poor prognosis group(＜5 points).Univariate analysis and multivariate Logistic regression were used to analyze whether serum Nesfatin-1 and 25(OH)D3 levels were risk factors for poor short-term prognosis in children with SE.The re-ceiver operating characteristic(ROC)curve was drawn to analyze the predictive value of serum Nesfatin-1 and 25(OH)D3 levels for the short-term poor prognosis in children with SE.Results At discharge,85 children[81.73％(85/104)]with a GOS score of 5 were included in the good prognosis group,and 19 children[8.27％(19/104)]with a GOS score of＜5 were included in the poor prognosis group.There was no significant differ-ence in gender,age,previous history of epilepsy,and seizure types between the two groups(P＞0.05).There were significant differences in the duration of SE,the time from medication to seizure cessation,electroenceph-alogram(EEG)results,head CT results,and serum Nesfatin-1 and 25(OH)D3 levels between the two groups(P＜0.05).Multivariate Logistic regression analysis showed that SE duration＞60 min,abnormal head CT results,serum Nesfatin-1 and 25(OH)D3 levels were independent risk factors for the short-term poor progno-sis of children with SE(OR=1.945,2.343,1.731,1.505;P＜0.05).The area under the ROC curve of serum Nesfatin-1 and 25(OH)D3 levels combined to predict poor short-term prognosis of children with SE was 0.840(95％CI:0.732-0.949),which was better than that of serum Nesfatin-1 and 25(OH)D3 levels alone[0.607(95％CI:0.453-0.761),0.742(95％CI:0.604-0.880)],respectively.Conclusion Serum Nesfatin-1 and 25(OH)D3 levels are risk factors for poor prognosis in children with SE,and the combination of them has high predictive value for poor prognosis in children with SE.
