Objective To compare the long-term survival of elderly patients with esophageal squamous cell carcinoma (ESCC) treated with surgical versus non-surgical treatment. Methods A retrospective analysis was conducted on the clinical data of elderly patients aged ≥70 years with ESCC who underwent esophagectomy or radiotherapy/chemotherapy at Sichuan Cancer Hospital from January 2009 to September 2017. Patients were divided into a surgical group (S group) and a non-surgical group (NS group) according to the treatment method. The propensity score matching method was used to match the two groups of patients at a ratio of 1∶1, and the survival of the two groups before and after matching was analyzed. Results A total of 726 elderly patients with ESCC were included, including 552 males and 174 females, with 651 patients aged ≥70-80 years and 75 patients aged ≥80-90 years. There were 515 patients in the S group and 211 patients in the NS group. The median follow-up time was 60.8 months, and the median overall survival of the S group was 41.9 months [95%CI (35.2, 48.5)], while that of the NS group was only 24.0 months [95%CI (19.8, 28.3)]. The 1-, 3-, and 5-year overall survival rates of the S group were 84%, 54%, and 40%, respectively, while those of the NS group were 72%, 40%, and 30%, respectively [HR=0.689, 95%CI (0.559, 0.849), P<0.001]. After matching, 138 patients were included in each group, and there was no statistical difference in the overall survival between the two groups [HR=0.871, 95%CI (0.649, 1.167), P=0.352]. Conclusion Compared with conservative treatment, there is no significant difference in the long-term survival of elderly patients aged ≥70 years who undergo esophagectomy for ESCC. Neoadjuvant therapy combined with surgery is still an important choice to potentially improve the survival of elderly patients with ESCC.

Persistent left superior vena cava is a rare venous variant that is often combined with cardiovascular malformations. In thoracic surgery, especially mediastinal tumor resection, neglect of this variant may make the surgery difficult and risky, and careful preoperative imaging interpretation and adequate preoperative evaluation play an important role in the perioperative safety of the patient. In this paper, we reported a case of a 17-year-old female patient with a persistent left superior vena cava combined with mediastinal tumors. She was successfully discharged 5 days after thoracoscopic surgery, and after 3 years of postoperative follow-up, no tumor recurrence was observed.

AIM: To study the effect of recombinant bovine basic fibroblast growth factor(re-bFGF)on cataract patients with low endothelial cell density(ECD)after phacoemulsification and intraocular lens implantation.METHODS: Prospective study. A total of 82 patients(82 eyes)with cataract and low ECD who received phacoemulsification and intraocular lens implantation in the hospital from January 2021 to December 2023 were selected and divided into observation group(41 eyes)and control group(41 eyes)by random coin tossing method. Both groups were treated with phacoemulsification and intraocular lens implantation, and received postoperative routine treatment. The control group was administrated with recombinant human epidermal growth factor(rhEGF)eye drops(1-2 drops each time, 4 times/day)on the basis of routine treatment, while the observation group was given re-bFGF eye drops(1-2 drops each time, 4 times/day)on the basis of routine treatment, and both groups were treated continuously for 3 mo. The postoperative uncorrected visual acuity recovery, cornea-related indicators [ECD, central corneal thickness(CCT), coefficient of variation in cell area(CV), percentage of corneal endothelial hexagonal cells(HEX)], serum inflammatory factors [tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β)and interleukin-6(IL-6)before and after surgery] and complications were compared between the two groups of patients.RESULTS: There were no differences in preoperative general data between the two groups. At 1 wk, 1 and 3 mo after surgery, the visual acuity in the two groups was improved compared with that before surgery(all P<0.05). The levels of corneal ECD and HEX in the observation group at 1 wk, 1 and 3 mo after surgery were higher than those in the control group, while the levels of CCT and CV were lower than those in the control group(all P<0.05). At 3 mo after surgery, levels of TNF-α, IL-1β and IL-6 in tears were lower in the observation group compared to the control group(all P<0.05). The total incidence rate of complications in the observation group was lower than that in the control group, with no statistical significance(P>0.05).CONCLUSION: The application of re-bFGF in cataract patients with low ECD after phacoemulsification and intraocular lens implantation has good clinical value. Additionally, it can relieve the corneal injury, and reduce the burden of inflammation.

Severe combined immunodeficiency (SCID) represents a group of genetically heterogeneous disorders characterized by mutations that lead to profound defects in both humoral and cellular immunity. Transplacental maternal engraftment (TME) is a frequently observed complication in SCID. While most cases of SCID with TME exhibit no substantial impact on disease progression, a subset of patients may encounter diagnostic delays or therapeutic challenges due to TME interference. Furthermore, TME may predispose these individuals to graft-versus-host disease (GVHD) prior to hematopoietic stem cell transplantation, thereby increasing diagnostic complexity and treatment risks. This review systematically examines the etiology and clinical manifestations of SCID associated with TME, analyzes its implications for disease management, and evaluates current detection methodologies. The synthesized evidence provides a theoretical foundation for future research and offers potential insights into the clinical diagnosis and management of SCID associated with TME.

Objective To explore the effect of the ratio of high-density lipoprotein cholesterol(HDL-C)/total cholesterol(TC)on no-reflow after percutaneous coronary intervention(PCI)in elderly patients with acute coronary syndrome(ACS)complicated with diabetes mellitus(DM).Methods A retrospective analysis was conducted on 206 elderly ACS patients complicated with DM undergoing PCI in our hospital from January 2018 to August 2024.The HDL-C and TC levels were detected by cholesterol oxidase test,and the HDL-C/TC ratio was calculated.Coronary angi-ography(CAG)was applied to evaluate no-reflow phenomenon after PCI,and according to the re-sults,the patients were divided into a non-reflow group(41 cases)and a normal reflow group(165 cases).ROC curve was plotted to evaluate the predictive performance of HDL-C/TC ratio for no-reflow after PCI in patients with ACS complicated DM.Results The no-reflow group had signifi-cantly higher TC and glycated hemoglobin A1c(HbA1c)levels and more balloon dilatations,but lower HDL-C level and HDL-C/TC ratio than the normal flow group(P＜0.01).Multivariate lo-gistic regression analysis showed that HbA1c(OR=3.196,95％CI:1.619-6.310,P=0.001),number of balloon dilatations(OR=3.504,95％CI:1.807-6.797,P=0.000),and HDL-C/TC ra-tio(OR=3.927,95％CI:2.0 73-7.441,P=0.000)were influencing factors of no-reflow after PCI in patients with ACS and DM.The AUC value of HDLC,TC,and HDL-C/TC ratio in predicting no-reflow after PCI was 0.842,0.726,and 0.922,respectively.Conclusion HDL-C/TC ratio is an influencing factor for no-reflow in patients with ACS and DM after PCI.The ratio at a cut-off val-ue of ≤0.21 has a certain predictive value for no-reflow after PCI in these elderly patients.

Objective:To investigate the reliability and validity of different measurement methods under 30° arthroscopy for quantifying the proportion of glenoid bone defect in bony Bankart lesions of the shoulder joint and validate its preliminary application effect.Methods:Eight intact shoulder glenoid specimens were selected, with no existing defects or deformities, from donors of 4 females and 4 males, with their age at death of 43-67 years [(54.4±8.0)years]. Bone defects of 12.5% and 25% were created in the glenoid at 0° and 45° relative to the longitudinal axis, with two specimens per defect category. The defect proportion in each specimen was quantified using direct measurement and CT-based digital reconstruction and these values served as reference standards for subsequent statistical analysis. Using a combined approach of arthroscopic simulation equipment and cadaveric study, five investigators performed simulated examinations through the standard posterior portal (2 cm medial and 1.5 cm inferior to the posterolateral acromial corner) and the modified posteroinferior portal (2 cm medial and 3 cm inferior to the posterolateral acromial corner) separately. Under 30° arthroscopy, the glenoid bone loss percentage was measured using the bare spot method and secant chord method. The reliability was analyzed for these measurements. Furthermore, using direct physical measurements and CT-based three-dimensional reconstruction data from the same specimens as reference standards, the comprehensive validity of four measurement methods was evaluated (standard posterior portal-bare spot method, standard posterior portal-secant chord method, modified posteroinferior portal-bare spot method, and modified posteroinferior portal-secant chord method). The independent validity of each method was assessed according to bone defect morphology classification to determine differences in measurement accuracy across defect types. In an arthroscopic procedure for a patient with Bigliani type IIIB bony Bankart lesion, the standard posterior portal-secant chord method was applied to quantify the proportion of glenoid bone defects.Results:The mean reference values from direct measurement and CT measurement of glenoid bone defect proportion in eight bony Bankart lesion specimens were 12.71%/12.37%, 13.17%/13.10%, 25.71%/24.9%, 26.6%/26.95%, 13.41%/13.10%, 12.90%/12.59%, 26.42%/25.94%, and 26.73%/27.06%, respectively. Measurements obtained by the five investigators showed intraclass correlation coefficients (ICCs) all greater than 0.90, indicating excellent interobserver agreement. In the validity analysis, the standard posterior portal-secant chord method demonstrated the highest overall validity. Using direct measurement and CT-based measurement as reference standards, the overall validity was (0.90±0.38)% and (1.07±0.53)% for the standard posterior portal-bare spot method, (1.33±0.40)% and (1.51±0.54)% for the modified posteroinferior portal-bare spot method, and (0.53±0.17)% and (0.70±0.38)% ( P<0.05) for the modified posteroinferior portal-secant chord method. In contrast, the standard posterior portal-secant chord method showed an overall validity of (0.10±0.10)% and (0.28±0.39)% ( P>0.05). In subsequent independent validity analyses, the standard posterior portal-secant chord method also demonstrated superior validity across all bone defect subtypes over the other three methods. In a patient with a Bigliani type IIIB bony Bankart lesion, we used the standard posterior portal-secant chord method to quantify the glenoid bone loss in 2 minutes, revealing a defect proportion of 26.6%. An arthroscopic autologous iliac bone graft procedure with single-tunnel elastic fixation guided by this measurement achieved favorable outcomes, with stable reduction, secure internal fixation and favorable recovery of shoulder function at 2 months postoperatively. Conclusion:For various types of bony Bankart lesions, the 30° arthroscopic standard posterior portal-secant chord method provides the most accurate quantification of glenoid bone loss and its preliminary clinical application yields satisfactory results.

Objective To investigate the therapeutic effect of dental pulp stem cells(DPSCs)on autoimmune hepatitis in in vivo and in vitro experiments and the related mechanism.Methods An in vitro co-culture system was used to evaluate the immunoregulatory effect of DPSCs,and 32 mice were randomly divided into healthy control group,model group,positive drug group,and DPSCs treatment group,with 8 mice in each group.The serum levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),and inflammatory factors were measured,and HE staining was used to assess liver pathological injury.An analysis of variance was used for comparison of normally distributed continuous data between multiple groups,and the least significant difference t-test was used for further comparison between two groups.Results The in vitro experiment showed that the positive rates of CD105,CD73,and CD90 in DPSCs were 99.97%,100%,and 99.53%,respectively,while the positive rates of CD34,HLA-DR,and CD45 were 0.56%,0.17%,and 0,respectively.DPSCs significantly inhibited the proliferation of Th1 and Th17 subsets,with inhibition rates of 31.32%and 45.76%,respectively;DPSCs promoted the proliferation of Treg(CD4+CD25+FoxP3+),with a promoting rate of 52.29%.DPSCs had an inhibition rate of 93.70%on the proliferation of lymphocytes.In the mouse model of autoimmune hepatitis,compared with the model group,the DPSCs treatment group had significant reductions in the serum levels of ALT and AST,with reduction rates of 66.8%and 60.0%,respectively(t=3.321 and 2.907,P=0.007 5 and 0.017 5)and significant reductions in the inflammatory factors tumor necrosis factor-α and interleukin-1β,with reduction rates of 57.5%and 71.3%,respectively(t=2.484 and 2.796,P=0.039 8 and 0.020 6),and histopathological examination showed no significant improvement in periportal bridging necrosis(t=1.969,P=0.098).Conclusion DPSCs effectively alleviate immune-mediated liver injury through immunoregulation,which provides an experimental basis for clinical translation.

Objective To investigate the feasibility of a "pericardial lining" modified Bentall procedure for the treatment of patients with aortic root aneurysm. Methods This was a retrospective study that consecutively enrolled patients treated at the Affiliated Suzhou Hospital of Nanjing Medical University, The Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, and the First People's Hospital of Guangyuan from January 2023 to February 2024. Preoperative clinical data, imaging findings (including echocardiography and CT scans of the aortic root and the entire aorta), details of coronary artery management, surgical outcomes, and postoperative follow-up results were collected. All patients underwent the "pericardial lining" modified Bentall procedure: the aortic valve was replaced, and an autologous pericardial patch was divided into three equal leaflets based on the circumference of the aortic annulus measured by a valve sizer. These leaflets were then sutured to the aortic annulus. Fenestrations were created in two of the pericardial leaflets for anastomosis with the left and right coronary ostia. The pericardial leaflets were sutured to the wall of the aortic sinuses to form an integrated structure, thereby narrowing the sinus portion. A prosthetic vascular graft was anastomosed to the proximal and distal aorta, and no aortic root-to-right atrium shunt was created. Results A total of 5 patients, aged 37 to 68 years, were included. The preoperative Society of Thoracic Surgeons (STS) risk scores ranged from 2.8% to 3.9%. The diameter of the ascending aorta was 40-73 mm, the left ventricular end-diastolic diameter (LVEDD) was 45-71 mm, and the left ventricular ejection fraction (LVEF) was 47%-64%. Intraoperatively, the aortic cross-clamp time ranged from 85 to 180 min, and the cardiopulmonary bypass time ranged from 110 to 302 min. Postoperative follow-up echocardiography revealed that the ascending aortic diameter was 27-35 mm, LVEDD was 39-57 mm, and LVEF was 43%-61%. All surgeries were completed successfully with satisfactory immediate outcomes and no intraoperative complications. During the follow-up period, there was no mortality or reoperation. Conclusion For patients with aortic root aneurysm, the "pericardial lining" modified Bentall procedure yields satisfactory preliminary results, and the technique is demonstrated to be feasible.

BackgroundPostpartum depression （PPD） is a prevalent postpartum complications that significantly compromises women's psychological and physical well-being. Repetitive transcranial magnetic stimulation （rTMS）， a conventional neuromodulation technique， has been increasingly used in the treatment of PPD. However， high-quality evidence regarding its efficacy and safety remains limited. ObjectiveTo evaluate the efficacy and safety of rTMS in the treatment of PPD， thereby providing references for clinical treatment. MethodsDatabases including Cochrane Library， PubMed， Embase， CNKI， Wanfang， VIP and China Biology Medicine disc （CBM） were electronically searched for randomized controlled trials （RCTs） on rTMS for PPD， with the search spanning from database inception to February 8， 2025. Study quality was assessed using the Cochrane Handbook for Systematic Reviews of Interventions 5.0.1， and the certainty of evidence was graded according to the Grading of Recommendations Assessment， Development and Evaluation （GRADE） approach. Meta-analysis was conducted using RevMan 5.3 and Stata 12.0. The outcomes of the Meta-analysis included the total effective rate， Edinburgh Postnatal Depression Scale （EPDS） score， Hamilton Depression Rating Scale （HAMD） score， and adverse reactions （dizziness， headache， nausea， diarrhea， and the overall incidence of adverse reactions）. ResultsA total of 11 studies involving 729 patients with PPD were included. Meta-analysis results showed that the total effective rate in the study group was significantly higher than that in the control group （OR=5.54， 95% CI： 3.07–10.01， P<0.01）. Both EPDS score （SMD=-2.38， 95% CI： -3.39–-1.37， P<0.01） and HAMD score （SMD=2.53， 95% CI： 1.21–3.85， P<0.01） in the study group were significantly lower than those in the control group， with statistically significant differences. Comparisons between the study group and control group reveal no significant differences in the incidence of dizziness and headache （RR=1.47， 95% CI： 0.63–3.43， P>0.05）， nausea （RR=1.46， 95% CI： 0.55–3.86， P>0.05）， diarrhea （RR=0.71， 95% CI： 0.23–2.20， P>0.05）， and overall adverse reactions （RR=1.30， 95% CI： 0.79–2.15， P>0.05）. GRADE assessment rated the four indicators of dizziness and headache， diarrhea， overall incidence of adverse reactions， and EPDS score as "moderate-certainty evidence"， and rated the total effective rate， nausea， and the HAMD score as "low-certainty evidence". ConclusionrTMS demonstrates certain therapeutic efficacy for PPD， with a safety profile comparable to conventional treatment. ［Funded by Sichuan Psychological Society Research Planning Project （number， SCSXLXH202403099）； Guiding Science and Technology Plan Project of Guangyuan （number， 23ZDYF0095）］

Objective:To explore the advantages of internet-based smart healthcare for full-cycle transcatheter edge-to-edge repair (TEER) management in reducing postoperative adverse events rate, improving cardiac function, and enhancing quality of life.Methods:This retrospective study enrolled patients with mitral regurgitation who underwent transcatheter TEER at Beijing Anzhen Hospital Valve Intervention Center between June 2021 and September 2023. Patients were classified into degeneration mitral regurgitation (DMR) and functional mitral regurgitation (FMR) according to etiology, with further stratification by enrollment period into usual care group (June 2021 to October 2022) and full-cycle management group (November 2022 to September 2023). The 1-year postoperative follow-up data were collected and compared between subgroups with the same etiology. Kaplan-Meier survival curves were plotted, and log-rank tests were used to compare the differences in major endpoint event-free survival rates between the two groups. Univariate and multivariate Cox regression and logistic regression analyses were performed to evaluate the impact of the full-cycle management system on patients′ outcomes.Results:A total of 130 patients were included, aged (72.0±8.6) years, including 82 (63%) males. DMR was identified in 84 cases (40 in the usual care group and 44 in the full-cycle management group), while FMR was observed in 46 cases (27 in the usual care group and 19 in the full-cycle management group). Kaplan-Meier analysis demonstrated higher 1-year major endpoint event-free survival rates in the full-cycle management group compared to the usual care group, though the difference was not statistically significant (log-rank P>0.05). Compared to the usual care group, the full-cycle management group showed significantly higher proportions of New York Heart Association classification Ⅰ-Ⅱ patients (DMR: 67% vs. 52%, P=0.031; FMR: 68% vs. 52%, P=0.021), greater 6-minute walking distances (DMR: (346.39±70.41) m vs. (294.11±60.47) m, P=0.012; FMR: (356.60±54.68) m vs. (318.55±39.02) m, P=0.004), and superior Kansas City Cardiomyopathy Questionnaire scores (DMR: 81.50 (74.50, 85.00) points vs. 71.00 (66.00, 82.25) points, P=0.014; FMR: 83.00 (76.00, 85.00) points vs. 74.00 (70.75, 80.00) points, P=0.030). Multivariate logistic regression confirmed the full-cycle management system as an independent predictor for the above improved outcomes (all P<0.05). Conclusion:Smart healthcare-based full-cycle management improves cardiac function and quality of life in mitral regurgitation patients after TEER, demonstrating lower rates of major endpoint events compared to usual care.
