Objective To observe the efficacy and safety of neoadjuvant sintilimab combined with chemotherapy in the treatment of patients with locally advanced resectable esophageal squamous cell carcinoma (ESCC). Methods Clinical data were collected from patients with locally advanced resectable ESCC who received neoadjuvant immunotherapy combined with chemotherapy followed by surgical treatment at the Department of Thoracic Surgery of Jining No.1 People's Hospital from April 2020 to April 2022. The endpoints included major pathological response (MPR), pathological complete response (pCR), R0 resection rate, safety, and postoperative survival. Results A total of 43 patients with ESCC who received at least one cycle of neoadjuvant immunotherapy before surgery were included. Among them, there were 31 males and 12 females with a median age of 65 years (interquartile range: 58-69). All patients successfully completed the surgery without any surgical delays. The pCR rate was 14.0% (6/43), the MPR rate was 58.1% (25/43), and the R0 resection rate was 97.7% (42/43). Patients exhibited reliable safety during neoadjuvant therapy and postoperatively. The 2-year overall survival and disease-free survival rates were 90.7% and 81.4%, respectively. Kaplan-Meier survival analysis and log-rank test revealed lower recurrence rates and better survival in the MPR patients compared to the non-MPR patients. Conclusion The combination of neoadjuvant sintilimab and chemotherapy in the treatment of patients with locally advanced resectable ESCC has demonstrated significant clinical efficacy, while also being safe and reliable.

Diabetic retinopathy is a common blinding complication in diabetic patients. Compared with conventional fundus color photography, fundus fluorescein angiography can dynamically display retinal vessel permeability changes, offering unique advantages in detecting early small lesions such as microaneurysms. However, existing intelligent diagnostic research on diabetic retinopathy images primarily focuses on fundus color photography, with relatively insufficient research on complex lesion recognition in fluorescein angiography images. This study proposed an adaptive multi-label classification model (D-LAM) to improve the recognition accuracy of small lesions by constructing a category-adaptive mapping module, a label-specific decoding module, and an innovative loss function. Experimental results on a self-built dataset demonstrated that the model achieved a mean average precision of 96.27%, a category F1-score of 91.21%, and an overall F1-score of 94.58%, with particularly outstanding performance in recognizing small lesions such as microaneurysms (AP = 1.00), significantly outperforming existing methods. The research provides reliable technical support for clinical diagnosis of diabetic retinopathy based on fluorescein angiography.

OBJECTIVE:
To investigate the feasibility and effectiveness of the novel bone hook combined with finger-guided technique in the treatment of irreducible intertrochanteric femoral fractures in elderly.
METHODS:
Between January 2021 and August 2023, 23 elderly patients with irreducible intertrochanteric femoral fractures were treated with the novel bone hook combined with finger-guided technique. There were 10 males and 13 females; the age ranged from 68 to 93 years (mean, 76.2 years). The time from injury to operation ranged from 36 to 76 hours (mean, 51.2 hours). According to the classification standard proposed by TONG Dake et alin 2021, there were 10 cases of typeⅠA, 1 case of typeⅠB, 6 cases of type ⅡA, 4 cases of type ⅡB, and 2 cases of type ⅡC. The operation time, intraoperative blood loss, intraoperative fluoroscopy frequences, and quality of fracture reduction were recorded. The fracture healing time and occurrence of postoperative complications were observed during follow-up. At last follow-up, the Harris scoring system was used to evaluate the hip joint function.
RESULTS:
The operation time was 42-95 minutes (mean, 52.1 minutes). The intraoperative blood loss was 40-420 mL (mean, 126.5 mL). Intraoperative fluoroscopy was performed 14-34 times (mean, 20.7 times). According to the criteria proposed by Chang et al, the quality of fracture reduction was rated as good in 20 cases and acceptable in 3 cases. All patients were followed up 6-20 months (mean, 10.2 months). X-ray film showed that all fractures healed with the healing time of 3.0-5.5 months (mean, 4.0 months). At last follow-up, the Harris score of the hip joint ranged from 82 to 97 points (mean, 90.4 points). Among them, 14 cases were rated as excellent and 9 cases as good. No complication such as coxa vara, cutting of the cephalomedullary nail, nail withdrawal, or nail breakage occurred during follow-up.
CONCLUSION
The treatment of elderly patients with irreducible intertrochanteric femoral fractures by using the novel bone hook combined with finger-guided technique can achieve high-quality fracture reduction and fixation, and has a good effectiveness.

To explore the inhibitory effect of ginkgolide B (GB) on MH7A human fibroblast-like synoviocytes (FLS) and its potential mechanism. Firstly, 20 μg/L tumor necrosis factor-α (TNF-α) was pretreated with MH7A to establish a cell model of arthritis. After incubation of MH7A cells with various concentrations of GB, CCK-8 assay, Transwell assay, and flow cytometry (FCM) were separately used to detect cell viability, cell invasion, and cell apoptosis rate and cell cycle; Real-time quantitative PCR and Western blot assay were performed to detect the apoptosis- and cycle-related gene transcriptions and protein expressions, respectively. The results showed that compared with the control group, GB dose- and time-dependently suppressed cell viability to a greater extent; GB significantly reduced cell invasive ability and increased cell apoptosis rate and proportion of G0/G1 phase in MH7A cells, along with increased transcription levels of Bcl-2-associated X protein (Bax) and p21 mRNA and decreased transcription levels of Bcl-2, myeloid cell leukemia 1(Mcl-1), protein kinase B (PKB; AKT), IP3K, Cyclin D1 and cyclin-dependent kinase 4 (CDK4) mRNA; GB remarkably increased expression levels of Bax, p21, and cleaved-Caspase 3 protein and decreased expression levels of Bcl-2, Mcl-1, p-AKT, p-PI3K, Cyclin D1, and CDK4 protein, with decreased ratios of p-PI3K/PI3K, p-AKT/AKT, and Bcl-2/Bax. In conclusion, GB blocks the G1-to-S cell cycle transition, suppresses cell viability and cell invasion and induces cell apoptosis of MH7A human RA-FLS via suppressing the PI3K/AKT signaling pathway.

Objective:To compare the preliminary efficacy and adverse events of chemoradiotherapy (CRT) with or without immunotherapy in bladder preservation therapy for localized muscle-invasive bladder cancer (MIBC) confined to the pelvis.Methods:Clinical data of 60 patients with MIBC who received CRT with or without immunotherapy for bladder preservation at the Cancer Hospital, Chinese Academy of Medical Sciences from January 2016 to June 2024 were retrospectively analyzed. Patients were divided into CRT plus immunotherapy group and CRT-alone group. Survival outcomes, bladder function preservation, recurrence and metastasis, as well as early and late radiation toxicities were evaluated. The Mann-Whitney U test was used for between-group comparisons. Overall survival (OS), progression-free survival (PFS), local recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) were estimated by the Kaplan-Meier method, and survival rates were compared by the log-rank test. Results:In the CRT plus immunotherapy group ( n=23), the median follow-up was 20 months. The median OS and median PFS were not reached. The 2-year OS, PFS, LRFS, and DMFS rates were 95.7%, 70.7%, 70.7%, and 92.9%, respectively, and 22 patients (96%) preserved normal bladder function. Patients with programmed death-ligand 1 (PD-L1) combined positive score (CPS) ≥1 had significantly higher 1-year PFS rate than those with CPS <1 (100% vs. 66.7%, P=0.004). In the CRT-alone group ( n=37), the median follow-up was 37 months, with median OS and PFS of 68 and 19 months, respectively. The 2-year OS, PFS, LRFS, and DMFS rates were 92.0%, 41.1%, 60.9% and 81.5%, respectively, and 33 patients (89%) preserved normal bladder function. Compared with the CRT-alone group, the CRT plus immunotherapy group showed a significant improvement in PFS ( χ2=4.38, P=0.036), while no significant differences were observed in OS, LRFS, or DMFS (all P>0.05). The incidence of acute hematologic toxicity in the CRT plus immunotherapy group and CRT-alone group were 52% (12/23), 27% (10/37) respectively, and late genitourinary toxicity was 22% (5/23), 8% (3/37), respectively, with no significant differences in overall acute or late toxicities (all P>0.05). Conclusions:For localized MIBC, bladder preservation with CRT combined with immunotherapy significantly improves PFS compared with CRT alone, while maintaining comparable safety. The PD-L1 status may serve as a favorable predictor for immunotherapy efficacy.

Thoracic aortic aneurysm (TAA) significantly endangers the lives of individuals with Marfan syndrome (MFS), yet the intricacies of their biomechanical origins remain elusive. Our investigation delves into the pivotal role of hemodynamic disturbance in the pathogenesis of TAA, with a particular emphasis on the mechanistic contributions of the mammalian target of rapamycin (mTOR) signaling cascade. We uncovered that activation of the mTOR complex 1 (mTORC1) within smooth muscle cells, instigated by the oscillatory wall shear stress (OSS) that stems from disturbed flow (DF), is a catalyst for TAA progression. This revelation was corroborated through both an MFS mouse model (Fbn1 +/C1039G) and clinical MFS specimens. Crucially, our research demonstrates a direct linkage between the activation of the mTORC1 pathway and the intensity in OSS. Therapeutic administration of rapamycin suppresses mTORC1 activity, leading to the attenuation of aberrant SMC behavior, reduced inflammatory infiltration, and restoration of extracellular matrix integrity-collectively decelerating TAA advancement in our mouse model. These insights posit the mTORC1 axis as a strategic target for intervention, offering a novel approach to manage TAAs in MFS and potentially pave insights for current treatment paradigms.
