Objective To investigate the therapeutic effect of folic acid combined with decitabine in diabetic retinop-athy(DR)mice with different methylenetetrahydrofolate reductase(MTHFR)genotypes.Methods The DR model mice were created by mating 20 MTHFR-/-mice with 20 wild-type C57 mice.A random number table method was employed to allocate 20 successfully modelled mice into the model group,DAC group,FA group,and FA+DAC group,with five mice assigned to each group.Five untreated MTHFR-/-and wild-type mice served as normal control.After constructing the DR model,the DAC group was injected intraperitoneally with 0.25 mg·kg-1 decitabine once every 5 days;the FA group was given 70 μg·kg-1 folic acid by tube feed once a day;the FA+DAC group was given 0.25 mg·kg-1 decitabine and 70μg·kg-1 folic acid at the same time;and the normal group was given an equal amount of physiological saline.All of the above groups were intervened for 30 days.OCT was employed for the measurement of retinal thickness,OCTA for retinal vascular density,histopathology(HE staining)for pathological changes in the mouse retina,real-time fluorescence quanti-tative PCR for mRNA expression,and Western blot analysis for protein expression levels.Results Compared with the wild-type model group,the degree of increase in retinal thickness and vascular density in the retinal layer was more pro-nounced in the MTHFR-/-mice model group(all P＜0.05).In wild-type mice,retinal thickness and retinal layer vessel den-sity were reduced in the DAC,FA and FA+DAC groups compared to the model group,with the FA+DAC group show-ing the greatest degree of reduction.The differences were all statistically significant(all P＜0.05);In MTHFR-/-mice,reti-nal thickness and vascular density in the retinal layer were reduced in the DAC group and the FA+DAC group compared to the model group(allP＜0.05).HE staining results showed an increased extent of retinal damage in the MTHFR-/-mice model group compared with the wild-type mice model group.Compared with the model group,the DAC group and the FA+DAC group had thinner retinas and more aligned ganglion cell layers in all types of mice,with the FA group having a worse effect and the FA+DAC group having a better treatment effect.The results of the polymerase chain reaction(PCR)revealed that the relative expression of the SAHH,MAT2A and DNMT1 proteins in the retinal tissues of the wildtype and MTHFR-/-mice model groups was elevated in comparison to the control group(all P＜0.05).Furthermore,the relative mR-NA expression of the DAC,FA and FA+DAC groups was reduced in comparison to the model group(all P＜0.05).In wild-type mice,the relative expression of MTHFR protein mRNA was decreased in the model group compared with the con-trol group,and increased in the DAC group,FA group,and FA+DAC group compared with the model group(all P＜0.05).Western blot results showed that the relative expression of DNMT1,MAT2A and SAHH proteins in the retinal tissues of the wild-type and MTHFR-/-mice model groups was higher than that of the control group(all P＜0.05),and the relative expression was lower in the DAC,FA,and FA+DAC groups compared with that in the model group(all P＜0.05).In wild-type mice,the relative expression of MTHFR protein in the retinal tissue of the model group was lower than that of the control group,and the relative expression of MTHFR protein in the FA group and the FA+DAC group was elevated com-pared with that of the model group(all P＜0.05).Conclusion The protective effect of folic acid combined with decit-abine on DR was superior to that of decitabine alone;treatment with folic acid in combination with decitabine may have yielded better efficacy in wild-type DR mice.

Objective:To evaluate the anti-reflux effect of digestive tract reconstruction using esophageal-tubular gastric asymmetric anastomosis after radical resection of esophageal and esophagogastric junction cancer.Methods:The main steps were as follows:(1)oblique incision of the lower esophagus;(2)curved incision of the tubular anterior gastric wall;(3)the lower end of the esophagus was anastomosed to the tubular gastric incision with a 90-degree torsion; (4)The anterior wall of the anastomosis was reinforced with a transverse-inverted suture,the posterior wall with a folded suture,and the corners of the gastric stump were buried with sutures.The anastomosis operation time,postoperative complications and postoperative hospital stay were recorded;the reconstructed structure and anti-reflux effect of the anastomosis were observed by digestive tract radiography,gastroscopy and follow-up investigation.Results:The Department of Gastrointestinal and Thoracic Surgery of Huaian First People's Hospital, affiliated to Nanjing Medical University, treated 5 patients of esophagogastric junction cancer and 20 esophageal cancer cases between August 2022 and November 2024, including 19 men and 6 women, with a mean age of (66.7±7.4) years. The mean anastomosis time was (35.4±5.9) minutes, the intraoperative blood loss was (117.6±33.4) ml and the mean postoperative hospital stay was(16.6±5.2) days, with no complications such as anastomotic leakage and bleeding. Postoperative digestive tract radiography (Trendelenburg position)showed that all the patients had no contrast reflux,gastroscopy showed no signs of reflux esophagitis and bile reflux gastritis, the anastomosis showed an inverted whiskers valve-like structure. The median follow-up time was (16.8±6.3) months, and all patients had no reflux symptoms such as acid reflux and belching,and no acid suppressive medication was needed.Conclusion:The esophageal-tubular gastric asymmetric anastomosis is a safe and effective antireflux reconstruction technique.

Objective This study aimed to adapt the data-driven Palliative Care Outcomes Collaboration(PCOC)model to the local context and evaluate its feasibility and preliminary effectiveness in a palliative care unit in China,with the goal of informing its broader integration into national palliative care practice.Methods Based on international experience,a localized implementation protocol for the PCOC model was developed through expert con-sultations and a pilot study.The protocol incorporated key elements including organizational and managerial sup-port,team training and capacity building,information system integration,supervision and feedback mechanisms,pro-cess optimization,and data-driven decision-making.From June to December 2023,the protocol was piloted in the palliative care unit of a tertiary cancer hospital in Changsha,China.Implementation outcomes were assessed by comparing patients' urgent care response rates,symptom stability rates,and symptom improvement rates between the first 1～3 months and 4～6 months after implementation.Results During the study period,a total of 355 inpatients were enrolled,with the PCOC assessment achieving full coverage(100％)and a completion rate of 97.78％.There was no statistically significant difference in the urgent needs response rate between the first 1～3 months and the 4～6 months after the implementation of the PCOC model(P=0.533).However,compared to the first 1～3 months af-ter implementation,patients in the 4～6 months period showed significantly higher symptom stability rates for pain,psychological/spiritual issues,and family/caregiver problems,as well as a higher improvement rate for pain(P＜0.05).Conclusion The localized PCOC implementation protocol facilitates standardized assessment and symptom manage-ment,and its application can enhance the quality of palliative care.

Objective To discuss the clinical efficacy of catheter-directed thrombolysis(CDT)in treating acute pulmonary embolism(APE).Methods A total of 215 patients with APE,who were admitted to the Second Affiliated Hospital of Shandong First Medical University of China,were enrolled in this study.Pulmonary angiography was performed in all the patients.After the location of the thrombus was identified,the pigtail catheter was rotated so as to break the thrombus into small pieces,which was followed by local infusion of thrombolytic agent urokinase to make recanalization of the occluded pulmonary artery.The postoperative clinical symptoms,blood oxygen saturation,mean pulmonary artery pressure,BNP,D-dimer,RV/LV diameter ratio were compared with their preoperative values.PESI scoring was used to evaluate the severity of the pulmonary embolism.Patients with PESI grade-Ⅲ and PESI grade-Ⅳ were classified into medium-risk group,and patients with PESI grade-V were classified into higher-risk group.Results Symptom relief immediately after surgery was observed in 210 patients,complete recanalization of pulmonary artery was achieved in 200 patients,and partial recanalization of pulmonary artery was seen in 15 patients.The preoperative mean pulmonary artery pressure,blood oxygen saturation,BNP,D-dimer,RV/LV diameter ratio were(46.24±5.32)mmHg,(90.36±3.23)％,(8 000.12±750.56)pg/mL,(7.5±2.3)mg/L and(1.63±0.22)respectively;at one week after surgery the above indicators were(26.12±3.36)mmHg,(98.74±2.12)％,(240.35±33.52)pg/mL,(1.75±0.36)mg/L and(1.11±0.13)respectively;the differences were statistically significant(all P＜0.05).In the patients who had symptoms of hemoptysis,shock and syncope before surgery,all these symptoms were completely disappeared in one week after CDT,and the symptoms of dyspnea,chest pain,and palpitations were significantly relieved after CDT,the differences were statistically significant(all P＜0.05).The difference in survival time between different PESI grade groups was statistically significant(P＜0.05).No serious postoperative complications such as severe arrhythmia,cerebral hemorrhage,or gastrointestinal bleeding occurred.Postoperative 3-month CT pulmonary angiography(CTPA)showed that the main pulmonary artery was well visualized and no thrombus-produced filling defect shadow was detected.Conclusion For the treatment of APE,CDT can promptly and rapidly open the obstructed pulmonary artery lumen,restore pulmonary artery hemodynamics,and correct hypoxemia.Therefore,CDT is a safe,effective and quick treatment for APE.

ObjectiveTo explore the mechanism of Hei Xiaoyaosan in improving the cognitive function in Alzheimer's disease （AD） from cell apoptosis mediated by the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/nuclear factor kappa B （NF-κB） signaling pathway. MethodsFour-month-old SD male rats were randomly assigned into a blank group， a sham group， a model group， a donepezil hydrochloride （0.45 mg·kg^-1） group， and high-， medium-， and low-dose （15.30， 7.65， and 3.82 g·kg^-1， respectively） Hei Xiaoyaosan groups， with 10 rats in each group. The sham group received bilateral hippocampal injection of 1 μL normal saline， while the other groups received bilateral hippocampal injection of 1 μL beta-amyloid 1-42 （Aβ_1-42） solution for the modeling of AD. Rats were administrated with corresponding agents once a day for 42 consecutive days. The Morris water maze test was carried out to assess the learning and memory abilities of rats. Hematoxylin-eosin staining was employed to observe pathological changes in the hippocampus of rats. Enzyme-linked immunosorbent assay was employed to measure the levels of cysteinyl aspartate-specific proteinase-3 （Caspase-3）， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax）. Western blot was employed to determine the protein levels of PI3K， Akt， and NF-κB. A cell model of AD was established by co-culturing Aβ_1-42 and PC12 cells in vitro. Cell viability and apoptosis were detected by the cell-counting kit 8 （CCK-8） assay and flow cytometry （FC）， respectively. ResultsAnimal experiments showed that compared with the blank group， the model group had a prolonged escape latency （P<0.01）， a reduced number of crossing platforms （P<0.01）， disarrangement and a reduced number of hippocampal neurons， up-regulated expression of Bax and Caspase-3， down-regulated expression of Bcl-2 （P<0.01）， decreased p-PI3K/PI3K and p-Akt/Akt levels， and an increased p-NF-κB/NF-κB level （P<0.01）. Compared with the model group， donepezil hydrochloride and high- and medium-dose Hei Xiaoyaosan shortened the escape latency and increased the number of crossing platforms （P<0.05， P<0.01）， improved the arrangement and increased the number of hippocampal neurons， down-regulated the expression levels of Bax and Caspase-3， up-reguated the expression level of Bcl-2 （P<0.05， P<0.01）， increased the p-PI3K/PI3K and p-Akt/Akt levels （P<0.05， P<0.01）， and reduced the p-NF-κB/NF-κB level （P<0.05， P<0.01）. Cell experiments showed that compared with the blank group， the model group exhibited an increased apoptosis rate （P<0.01）. Compared with the model group， the serum containing Hei Xiaoyaosan at various doses improved the cell viability （P<0.01）， and the serum containing Hei Xiaoyaosan at the high dose decreased the cell apoptosis （P<0.01）. ConclusionHei Xiaoyaosan may improve the learning and memory abilities of AD model rats by regulating cell apoptosis， while increasing the vitality and reducing the apoptosis rate of AD model cells via the PI3K/Akt/NF-κB signaling pathway.

Five previously undescribed diterpenoids, named succipenoids D‒H (1‒5), along with four undescribed lignans, named succignans A‒D (6‒9), were isolated from the dichloromethane extract of Chinese medicinal succinum. Compounds 1‒5 were characterized as nor-abietane diterpenoids, while compounds 6‒9 were identified as lignans polymerized from two groups of phenylpropanoid units. The structures of these novel compounds, including their absolute configurations, were determined through spectroscopic and computational methods. Biological assessments of renal fibrosis demonstrated that compounds 6 and 7 effectively reduce the expression of proteins associated with renal fibrosis, including α-smooth muscle actin (α-SMA), collagen I, and fibronectin in transforming growth factor-β1 (TGF-β1) induced normal rat kidney proximal tubular epithelial cells (NRK-52e).

Objective To investigate the factors affecting the occurrence of new postoperative cardiac complications in patients undergoing esophageal cancer surgery with concomitant coronary heart disease. Methods Clinical data of patients who underwent esophageal cancer surgery with coronary heart disease at the Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University from December 2019 to June 2023 were collected. Patients were divided into two groups based on whether they experienced postoperative cardiac complications. Using the occurrence of cardiac complications as the dependent variable, a multivariate logistic regression model was established to identify related influencing factors. Results A total of 223 patients were included, comprising 148 males and 75 females, with an average age of (71.78±6.31) years (range 53-88 years). Seventy-one (31.84%) patients experienced at least one new cardiac complication postoperatively, including 2 acute coronary syndrome, 13 heart failure, and 59 new-onset postoperative arrhythmias. Univariate analysis showed that age, systemic immune-inflammation index, pulmonary infection, need for invasive mechanical ventilation due to respiratory failure, acute respiratory distress syndrome (ARDS), acute delirium, pleural effusion requiring drainage, and acute renal failure were risk factors for postoperative new-onset cardiac complications (all P<0.05). Multivariate logistic regression analysis identified age, postoperative length of hospital stay, ARDS, and systemic immune-inflammation index as independent risk factors for new cardiac complications in esophageal cancer patients with coronary heart disease. Conclusion Strengthening perioperative management of esophageal cancer patients, ranging from preoperative evaluation to postoperative complication treatment, is crucial. Particular attention should be paid to age, ARDS, and other indicators to improve postoperative prognoses in patients with coronary heart disease complicated by esophageal cancer.
