Background: s/Aims: Distal pancreatectomy with splenectomy (DPS) is a common surgical procedure for pancreatic body cancer.However, spleen-preserving distal pancreatectomy (SPDP) utilizing the Warshaw technique (WT) in malignancies is generally not favored due to concerns about inadequate resection. This study aims to assess the feasibility and oncologic outcomes of employing SPDP with WT in pancreatic body cancer. Methods: We conducted a retrospective analysis comparing 21 SPDP patients with 63 DPS patients matched by propensity score from January 2018 to November 2022. Clinical outcomes and follow-up data were analyzed using R. Results: Both groups exhibited similar demographic, intraoperative, and pathological characteristics, with the exception of a reduced number of total lymph nodes (p = 0.006) in the SPDP group. There were no significant differences in the rates of postoperative complications, recurrence, or metastasis. Local recurrence predominantly occurred in the central region as opposed to the spleen region.There were no cases of isolated recurrences in the splenic region. Median overall survival and recurrence-free survival times were 51.5 months for SPDP vs 30.5 months for DPS and 18.7 months vs 16.8 months, respectively (p > 0.05). The incidence of partial splenic infarction and left-side portal hypertension in the SPDP group was 28.6% (6/21) and 9.5% (2/21), respectively, without necessitating splenic abscess puncture, splenectomy, or causing bleeding from perigastric varices. Conclusions SPDP did not negatively impact local recurrence or survival rates in selected pancreatic body cancer patients. Further studies are necessary for validation.

Objective To explore the feasibility and safety of using indocyanine green combined with autologous blood and methylene blue for localization of small lung nodules during thoracoscopic wedge resection. Methods Patients who underwent CT-guided percutaneous lung puncture injection of localization agents to locate lung nodules at the First Affiliated Hospital of Fujian Medical University from November 2023 to January 2024 were selected. Under thoracoscopy, lung nodules were located by white light mode, fluorescence mode, or near-infrared mode and wedge resection was performed. The feasibility of using indocyanine green combined with autologous blood and methylene blue for localization of small lung nodules was preliminarily verified by evaluating whether the localization agent concentrated around the nodules, and the safety of this method was verified by analyzing the incidence of adverse reactions during patient puncture and surgery. Results A total of 30 patients with lung nodules were included, including 10 males and 20 females, with an average age of (55.5±11.2) years. In 26 patients, the amount of localization agent used was moderate, the localization agent concentrated around the nodules, and successful precise localization of small lung nodules was achieved. In 4 patients, due to excessive use of localization agent, the marker was diffuse with pleural staining. The overall localization success rate was 86.7%, and when the injection volume of localization agent was 0.2-0.5 mL, the localization success rate was 100.0%. All patients successfully completed thoracoscopic wedge resection and found nodule lesions, with negative margins and a distance from the margin to the lesion that met the requirements. There were no complications. Conclusion Thoracoscopic surgery using indocyanine green combined with autologous blood and methylene blue for localization of small lung nodules is safe and feasible.

Objective To investigate the prognosis and satisfaction of the R2 intervention procedure and develop related predictive models. Methods The clinical data of 64 patients with primary craniofacial hyperhidrosis who underwent R2 intervention surgery at the First Affiliated Hospital of Fujian Medical University from November 2018 to October 2022 were retrospectively analyzed. By statistically analyzing the risk factors for compensatory hyperhidrosis (CH) and satisfaction, and conducting feature screening, a relevant prediction model was established. Results Finally, 51 patients were collected, including 43 (84.3%) males and 8 (15.7%) females, with an average age of (30.27±7.22) years. Overall postoperative satisfaction was high, with only 5.9% of patients expressing regret about the surgery. However, 92.2% of patients experienced CH. The onset of postoperative CH was most prominent within the first 3 months postoperatively, with the incidence rate stabilizing thereafter. Preoperative heart rate and R2 sympathetic nerve clipping were identified as independent risk factors for severe CH. The preoperative body mass index, the degree of sweating in the chest and abdomen, are significantly correlated with postoperative satisfaction. Conclusion The R2 intervention surgery effectively alleviates the symptoms of primary craniofacial hyperhidrosis, and patient satisfaction is high.

Objective:To explore the diagnosis and treatment of lymphoepithelioma-like intrahepatic cholangiocarcinoma(LEL-ICC).Methods:The retrospective and descriptive study was conducted. The data of 7 patients with pathological diagnosis of LEL-ICC after hepatectomy who were treated in Lishui Central Hospital in Zhejiang Province from December 1, 2009 to January 30, 2024 were collected. There were 2 males and 5 females. The age range was from 40 to 64 years old, with a median age of 52 years old. All 7 patients showed no obvious clinical symptoms.We analysed the imaging manifestations, pathological features, treatmentsand prognoses of patients.Postoperative follow-upswere conducted via telephone, with a focus on whether the patient had relapsed. The deadline was February 20, 2024.Results:Five cases underwent ultrasound examination, of which 4 cases showed hypoechogenicity and 1 case showed hyperechogenicity. 7 cases underwent MRI examination, showing low signal on T1WI, high signal on T2WI, and high signal on diffusion-weighted imaging. 2 cases had type A enhancement, 2 cases had type B enhancement, and 3 cases had type C enhancement. All 7 cases received surgical treatment, 2 cases were received prophylactic transarterial chemoembolization (TACE) after surgery, and 3 cases were received systemic chemotherapy after surgery; All 7 cases underwent postoperative follow-up, with a follow-up time of 1-166 months and a median follow-up time of 56 months. One case developed hilar and retroperitoneal lymph node metastasis after surgery for 6 months, and underwent surgical treatment. After surgery, chemotherapy was performed. 25 months later, right adrenal gland metastasis reappeared, and after combined treatment, the metastatic lesion was reduced and the patient received surgical treatment and chemotherapy, and there is currently no recurrence. The remaining 6 cases showed no recurrence.Conclusions:LEL-ICC lacks specific clinical symptoms and imaging manifestations, diagnosis relies on histopathological and immunohistochemical examinations. Comprehensive treatment with surgical intervention as the main approach can lead to better prognosis for patients.

AIM:To explore the mechanism of ac-tion of the microtubular inhibitor of CA-4 deriva-tive LGD5 on human cervical cancer HeLa cells.METHODS:HeLa cells were selected and divided in-to blank group,CA-4 positive control group,and dif-ferent concentrations of LGD5 were formed into the experimental group.MTT was used to investi-gate the growth inhibition of LGD5 on HeLa cells and to determine the assay concentration.Cell morphology and apoptosis were observed before and after drug administration by inverted micro-scope and acridine orange staining.Immunofluo-rescence staining was used to examine the effect of LGD5 on microtubules using DAPI.The effect of LGD5 on cell cycle by PI flow cytometry.Protein im-munoblotting was used to examine the effect of LGD5 on cyclins and apoptosis-related proteins.RE-SULTS:MTT experiments showed that LGD5 inhibit-ed HeLa cells in a time-and dose-dependent man-ner.Timed photography and acridine orange stain-ing observed that LGD5 induced apoptosis in HeLa cells and produced significant chromatin agglutina-tion and apoptotic bodies.Inhibition of microtu-bule polymerization in HeLa cells by LGD5 was ob-served by DAPI staining.The PI flow cytometry re-sults showed that LGD5 induced G2/M cycle arrest in HeLa cells,was time-dependent and dose-depen-dent within 12 h,and had a significant difference(P＜0.01),apoptosis was induced after 24 h and it was time-dependent.The results of Western blot show that,LGD5 downregulates Cdc 2 and Cdc25C,up-regulation of p-Cdc 2,and Cyclin B1 and p-histone H3,further verified that LGD5 induced G2/M cycle arrest in HeLa cells,besides,LGD5 caused in-creased Caspase 3 expression in HeLa cells,upregu-lated Caspase 9 and Bax,down-regulation of Pro-caspase 9 and Bcl-2,this result indicates that HeLa cell apoptosis induced by LGD5 is related to the mi-tochondrial pathway.CONCLUSION:The CA-4 deriv-ative LGD5 inhibited microtubule polymerization in HeLa cells,induced their G2/M cycle arrest,and subsequently induced cell apoptosis through the mitochondrial pathway.

Objective:To investigate the current status of sarcopenia and self-management in elderly patients with type 2 diabetes mellitus (T2DM), and to explore the identification of risk factors for sarcopenia by diabetes self-management ability.Methods:Using convenience sampling, 284 elderly patients with T2DM who visited a community health service center in Beijing from March to September 2023 were selected as subjects. The patients were screened for sarcopenia and received related health examinations based on Asian working group for sarcopenia (AWGS) 2019 Consensus. Surveys were conducted using general information questionnaire, the Summary of Diabetes Self-Care Activities measure, and other questionnaires. Patients were divided into groups according to the presence or absence of muscle attenuation (defined as suspected and confirmed sarcopenia).Results:The prevalence of muscle attenuation in the 284 elderly patients with T2DM was 48.9%, and the prevalence of sarcopenia was 15.9%. The proportions of females, patients who are over 70 years old, and patients with a sedentary lifestyle were significantly higher in the group with muscle attenuation compared with the group without muscle attenuation. High-quality protein intake, extremity skeletal muscle mass index, grip strength, and six-meter walking speed were significantly lower in the muscle attenuation group. Binary logistic regression analysis revealed that age, alcohol consumption, a sedentary lifestyle, and high-quality protein intake were influencing factors for sarcopenia in elderly patients with T2DM ( P<0.05). The total self-care scores and subtotals in exercise domains showed significant differences ( P<0.05) between patients with and without muscle attenuation. Univariate analysis indicated significant differences in self-management behaviors among patient groups stratified by grip strengths and 6-meter walk speeds ( P<0.05). Multivariate linear regression analysis showed that grip strength and 6-meter walk speed were influencing factors for exercise management behaviors in elderly patients with T2DM ( P<0.05). Conclusions The prevalence of sarcopenia in elderly patients with T2DM is relatively high, and their level of diabetes self-management is medium to low. Practitioners should pay extra attention to patients who are over 70 years old, with sedentary habits, with low intake of high-quality protein, and females. It's recommended to use grip strength and 6-meter walk speed tests as initial screening tools for sarcopenia in elderly patients with T2DM, in order to identify risks early and implement targeted health management to promote the development of good self-management behaviors among patients.

Objective To investigate the impact of cardiomyocyte ferroptosis on acute myocardial infarction(AMI)and its relationship with the expression of long non-coding RNA(lncRNA)GAS5.Methods An AMI model was established in eighteen male SD rats(6-8 weeks old),and then the subjected rats were randomly divided into blank control group,sham operation group,and model group,6 animals in each group.In 2 weeks after surgery,echocardiography was used to evaluate heart function,and TTC staining,HE staining and TUNEL staining were employed re-spectively to observe myocardial infarct area,histopathological changes of myocardial tissues and apoptosis in cardiomyocytes.Serum Fe2+concentration was measured with an iron ion detection kit.The expression levels of lncRNA GAS5,nuclear factor erythroid-derived 2-like 2(Nrf2),and glutathione peroxidase 4(GPX4)in myocardial tissues were detected with QT-PCR.Linear corre-lation analysis was performed to investigate the relationship between the expression of lncRNA GAS5,Nrf2 and GPX4 with Fe2+concentration.Western blotting was conducted for the protein levels of ferroptosis-related proteins,glutathione peroxidase 4(GPX4),nuclear factor erythroid-derived 2-like 2(Nrf2),glucose-regulated protein 78(GRP78),and cysteinyl aspartate specific proteinase 12(Caspase-12)in myocardial tissues.Results Western blotting revealed obvious in-creases in the protein levels of ferroptosis related proteins GRP78(1.11±0.13 vs 0.51±0.08,P＜0.01)and Caspase-12(1.23±0.05 vs 0.92±0.07,P＜0.05)and a decrease in those of ferroptosis inhibitor GPX4(0.27±0.11 vs 0.68±0.10,P＜0.01)and Nrf2(0.30±0.12 vs 0.58±0.04,P＜0.05)in the model group than the sham operation group.Additionally,QT-PCR showed that the mRNA levels of GPX4 and Nrf2 were notably lower,indicating cardiomyocyte ferroptosis,while that of lncRNA GAS5 was remarkably higher in the myocardial tissues of the model group than the sham operation group(P＜0.01).What's more,the expression of lncRNA GAS5 had a positive correlation with serum Fe2+concentration(P＜0.05).Conclusion AMI is closely associated with cardiomyocyte ferroptosis.lncRNA GAS5 is involved in the regulation of ferroptosis by Nrf2/GPX4 signaling pathway,which thus mediating the occurrence of heart failure after AMI.

Objective:To observe the clinical effect of adjustable silicone strap suspension in the treatment of myasthenia gravis ptosis.Methods:From January 2019 to January 2020, 60 patients with myasthenia gravis ptosis (35 males, 25 females, age distribution from 25 to 58 years, with average of 35.63 years) were collected from the Department of Ophthalmoplasty of Aier Eye Hospital affiliated to Wuhan University. They were divided into control group and observation group, with 30 cases in each group. The observation group was treated with adjustable silicone band suspension, and the correction effect, satisfaction, recovery status, ocular surface function index, recurrence rate and complications of the two groups were compared.Results:The excellent rate of operation in the observation group was 93.33% (28/30), which was significantly higher than 63.33% (19/30) in the control group (χ 2=6.29, P<0.05), and the satisfaction of patients in the observation group was 100% (30/30), which was significantly higher than 76.67% (23/30) in the control group (χ 2=5.82, P<0.05). The preoperative corneal curvature and fluorescein staining in the observation group and the control group were significantly lower than those in the postoperative state ( t=6.17, 21.48, P<0.05). The corneal curvature and fluorescein staining score of the observation group were significantly higher than those of the control group at 3 months after surgery ( t=3.00, 9.06, P<0.05). There was no significant difference between the two groups in the incidence of complications such as eyelid imclosure, upper eyelid inversion and unnatural upper eyelid curvature (χ 2=0.19, P>0.05). Follow up at 3 months after surgery, the recurrence rate in the observation group was lower than that in the control group (χ 2=4.63, P<0.05). Conclusions:Surgery is an option for patients with myasthenia gravis ptosis who are not responding well to medical treatment and whose condition is stable. Adjustable silicone strap suspension for the treatment of myasthenia gravis ptosis can significantly improve the surgical success rate and patient satisfaction, with low postoperative complication rate and recurrence rate, which is suitable for clinical application.
