OBJECTIVE To compare the anti-hepatitis mechanisms of Abrus pulchellus subsp. cantoniensis （Hance） Verdc. （AC） and Abrus pulchellus subsp. mollis（Hance） Verdc. （AM）. METHODS SD rats were randomly divided into blank group， AC- treated group， and AM-treated group， with each group consisting of 10 rats. The rats’ orbital venous blood was collected at 5， 15， 30 minutes， and 1， 1.5， 2， 4， 6， 8， 12 hours after gavage administration of 24 g/kg of the corresponding drug （calculated by crude drug） or water， respectively. Ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry technology was utilized to identify the prototype components present in the serum. The network pharmacology method was adopted to predict the anti-hepatitis active components， key targets， and signaling pathways of AC and AM. Additionally， molecular docking technology was utilized to verify the binding activity of the core active components with key targets. RESULTS A total of 35 prototype components migrating to the blood of AC and AM were identified in the serum of administered rats， among which 24 were common components. The active components in AC， such as acetylanguidine， physcion， soyasaponin A3 and soyasaponin Ⅰ， as well as those in AM， including vicenin 3， acetylanguidine，soyasaponin Ⅰ and schaftoside， all acted on key targets such as steroid receptor coactivator， phosphatidylinositol-4，5-bisphosphate 3-kinase catalytic subunit alpha， epidermal growth factor receptor （EGFR）， and protein kinase B1（Akt1）. These components modulated pathways in cancer， EGFR tyrosine kinase inhibitor resistance， and the phosphoinositide 3-kinase （PI3K） -Akt pathway， thereby exerting anti-hepatitis effects. Furthermore， the binding energies between these active components and their key targets were all less than －5 kJ/mol. CONCLUSIONS There are differences in the active components of AC and AM against hepatitis， but their mechanisms of action are similar. Both may exert their anti-hepatitis effects through pathways in cancer， EGFR tyrosine kinase inhibitor resistance， and the PI3K-Akt pathway.

OBJECTIVE: To investigate the current status of long-term quality of life in patients with severe acute pancreatitis (SAP) who have been cured and discharged, and to analyze the influencing factors affecting long-term quality of life in SAP cured patients after discharge. METHODS: A retrospective collection was conducted. Patients who were received standardized treatment before being cured and discharged from the hospital admitted to the first department of critical care medcine of the Second Affiliated Hospital of Anhui Medical University from January 2017 to December 2023 were enrolled. According to the 36-item short form health survey scale (SF-36) score, patients were divided into high score group (high quality of life, the top 50% of patients with total SF-36 score) and low score group (low quality of life, the bottom 50% of patients with total SF-36 score). The gender, age, history of hypertension and diabetes, etiology of pancreatitis, acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA), CT severity index (CTSI), laboratory indicators such as C-reactive protein (CRP), procalcitonin (PCT), blood glucose, and triglycerides upon admission, use of vasoactive drugs, non-invasive/high-flow ventilation, invasive ventilation, retroperitoneal puncture and drainage, open pancreatic surgery treatment and secondary infection during hospitalization were collected, as well as the retention of abdominal drainage tubes at discharge from hospital. Distribute follow-up questionnaires or telephone follow-up surveys through WeChat and Question Star programs to investigate the pancreatic secretion function, chronic abdominal pain, and recurrence of pancreatitis of patients after discharge. Multivariable Logistic regression was used to analyze the relevant factors affecting the long-term quality of life of cured patients with SAP. RESULTS: A total of 86 patients were ultimately enrolled. There were 43 patients in both the high and low score groups. Among 86 patients, 20 experienced acute pancreatitis recurrence, with a recurrence rate of 23.26%. Twenty-two (25.58%) experienced chronic abdominal pain after discharge, and 5 patients (5.81%) needed medication to relieve pain. Thirty-three patients (38.37%) had pancreatic exocrine dysfunction after discharge, characterized by abdominal distension, constipation or diarrhea. Twenty-two patients (25.58%) suffered from pancreatic endocrine dysfunction, and were diagnosed with diabetes. Univariate analysis showed that compared with the high score group, the low score group had more patients with hypertension, initial renal dysfunction, initial severe metabolic acidosis, initial serum calcium < 2.0 mmol/L, blood glucose > 11.1 mmol/L and cultured Gram positive bacteria (from blood/body fluid/pancreatic necrotic tissue) during treatment (48.84% vs. 16.28%, 60.47% vs. 32.56%, 18.60% vs. 4.65%, 88.37% vs. 62.79%, 55.81% vs. 30.23%, 34.88% vs. 13.95%), had higher CTSI score (6.60±1.61 vs. 5.77±1.32), lower hemoglobin level at discharge (g/L: 102.30±18.78 vs. 110.72±16.68), and a lower proportion of etiological interventions after discharge (34.88% vs. 67.44%), the differences were statistically significant (all P < 0.05). Multivariate Logistic regression analysis showed that hypertension [odds ratio (OR) = 4.814, 95% confidence interval (95%CI) was 1.196-19.378], initial serum calcium < 2.0 mmol/L (OR = 6.688, 95%CI was 1.321-33.873) and initial blood glucose > 11.1 mmol/L (OR = 6.473, 95%CI was 1.399-29.950) were risk factors for long-term quality of life in cured SAP patients (all P < 0.05), while post discharge prophylactic intervention was a protective factor for long-term quality of life (OR = 0.092, 95%CI was 0.020-0.425, P < 0.01). CONCLUSIONS Cured SAP patients have varying degrees of impaired secretion function and the possibility of recurrence of acute pancreatitis. Hypertension, initial serum calcium < 2.0 mmol/L and blood glucose > 11.1 mmol/L are independent influencing factors for low long-term quality of life in cured SAP patients. Prevention and intervention targeting the etiology of pancreatitis after discharge can improve the long-term quality of life of cured SAP patients.

Promoting the construction of a “Healthy China” is essential to building a great modern socialist country. Health workers in every era have their historical missions and they are the “benevolent doctors” of their own era. Therefore， clarifying the basic connotation and times requirements of “benevolent doctors” has become the first question to be answered in cultivating “benevolent doctors”. The basic connotation of “benevolent doctor” should reflect not only the comprehensive development of moral， intellectual， physical， aesthetic， and labor education in fostering virtue and nurturing talents， but also embody the people-centered development philosophy， promote social equity and justice， and reflect the strategic needs of building a “Healthy China.” Specifically in the practice of medical education， emphasizing both medical science spirit and medical humanities spirit has become an important path to cultivate “benevolent doctors” in the new era.

Objective:To evaluate the efficacy of high-flow nasal cannula oxygen therapy for lumbosacral plexus block combined with intravenous anesthesia for hip replacement in elderly patients.Methods:Twenty-two elderly patients of either sex, aged 65-89 yr, with a body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, scheduled for elective lateral approach to unilateral hip replacement, capable of cooperating to complete the Mini-Mental State Examination with a score of ≥25, were included. Preoperative lumbosacral plexus block was performed on the affected side under ultrasound guidance. Sufentanil 0.1 μg/kg was intravenously injected at 5 min before skin incision, and propofol was given by target-controlled infusion at a plasma target concentration of 1.0-2.0 μg/ml. During the operation, spontaneous breathing was preserved and high-flow nasal cannula oxygen therapy was performed. FiO 2 was set at 60%, gas flow rate at 60 L/min, temperature at 37 ℃, humidity at 100%. The values of Bispectral Index were 60 -75, and the Surgical Pleth Index value was 30-60. If the Surgical Pleth Index value > 60, an additional sufentanil 0.05 μg/kg was added. PaO 2, FiO 2 and PaCO 2 were recorded immediately before nerve block (T 1), immediately after the start of surgery (T 2), 30 min after the start of surgery (T 3), 90 min after the start of surgery (T 4), immediately after the end of surgery (T 5) and immediately after leaving postanesthesia care unit (T 6). Lung ultrasound scores were recorded at T 1 and T 6. The development of intraoperative hypotension, bradycardia and hypoxemia and occurrence of postoperative nausea and vomiting, new pulmonary infection, delirium and cognitive dysfunction were recorded. Results:Nerve block was completed within 15 min in all the patients, and all the patients underwent surgery successfully. PaO 2/FiO 2 increased at T 4 and T 5, while at T 6 it decreased to the level observed at T 1 ( P<0.05); PaCO 2 increased at T 2-T 6 and reached the peak value at T 2 ( P<0.05). There was no significant difference in lung ultrasound scores at all time points ( P>0.05). There were 8 patients (36%) with hypotension and 2 patients (9%) with bradycardia, and no hypoxemia was found during operation. Postoperative nausea and vomiting occurred in 2 cases (9%) and delirium in 2 cases (9%), and no new pulmonary infection or cognitive dysfunction was found after operation. Conclusions:High-flow nasal cannula oxygen therapy can be safely and effectively used in elderly patients undergoing hip replacement with lumbosacral plexus block combined with intravenous anesthesia.

To evaluate the feasibility and safety of dilation treatment under the guidance of precise puncture assisted with double endoscopes for anastomotic atresia after colorectal cancer surgery, 3 cases with anastomotic atresia after colorectal cancer surgery were treated precisely under endoscopy. The first colonoscopy was introduced through the terminal ileum stoma to anastomotic site, another endoscope was inserted through the anus to the anastomosis. Precise puncture of the contralateral intestinal cavity was done through light source positioning. The puncture needle was seen under the direct vision of endoscope, and then the guide wire was inserted. Anastomosis was dilated by the balloon through the guide wire. Endoscopic recanalization of anastomotic atresia was successfully completed in 3 patients. No complication occurred during the treatment with the mean operation time of 44.3 minutes. The ileal terminal stoma reduction surgery was performed 1-3 months after endoscopic treatment. Dilation treatment under the guidance of precise puncture assisted with double endoscopes for anastomotic atresia after colorectal cancer surgery is reliable with the advantages of short operation time, safety and convenience, and no need for X-ray assistance.
