Donors with a serum sodium concentration of >155 mmol/L are extended criteria donors for liver transplantation (LT). Elevated serum sodium of donors leads to an increased incidence of hepatic dysfunction in the early postoperative period of LT; however, the exact mechanism has not been reported. We constructed a Lewis rat model of 70% hepatic parenchymal area subjected to ischemia-reperfusion (I/R) with hypernatremia and a BRL-3A cell model of hypoxia-reoxygenation (H/R) with high-sodium (HS) culture medium precondition. To determine the degree of injury, biochemical analysis, histological analysis, and oxidative stress and apoptosis detection were performed. We applied specific inhibitors of the epithelial sodium channel (ENaC) and Na+/Ca2+ exchanger (NCX) in vivo and in vitro to verify their roles in injury. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) levels and the area of hepatic necrosis were significantly elevated in the HS+I/R group. Increased reactive oxygen species (ROS) production, myeloperoxidase (MPO)-positive cells, and aggravated cellular apoptosis were detected in the HS+I/R group. The HS+H/R group of BRL-3A cells showed significantly increased cellular apoptosis and ROS production compared to the H/R group. The application of amiloride (Amil), a specific inhibitor of ENaC, reduced ischemia-reperfusion injury (IRI) aggravated by HS both in vivo and in vitro, as evidenced by decreased serum transaminases, inflammatory cytokines, apoptosis, and oxidative stress. SN-6, a specific inhibitor of NCX, had a similar effect to Amil. In summary, hypernatremia aggravates hepatic IRI, which can be attenuated by pharmacological inhibition of ENaC or NCX.

Objective:The high-quality clinical studies published in the field of hypertriglyceridemia associated acute pancreatitis (HTG-AP) were summarized to analyze the incidence and trends of HTG-AP in China.Methods:Clinical studies related to acute pancreatitis in PubMed, Medline, Cochrane Library and Web of Science from January 1, 2000 to November 12, 2021 were searched and screened. Keywords included China, acute pancreatitis, and clinical study. According to the inclusion and exclusion criteria, related literature were accurately selected and evaluated before extracting data. Meta-analysis was performed using R4.2 and RevMan5.3 software. The effect sizes of annual average percentage change (AAPC) for acute pancreatitis in different regions were merged and forest plot was drawn. Patients were divided into severe acute pancreatitis (SAP) group, moderately severe acute pancreatitis (MSAP) group and mild acute pancreatitis (MAP) group, and forest plot was drawn to analyze the AAPC of HTG-AP. Regression curve for time-dependent changes in the percentage of AP with different etiological factors was constructed.Results:Totally, 67 articles (33 randomized clinical trials, 34 retrospective cohort study) and 30 421 patients were included. The meta-analysis showed that the proportion of HTG-AP among AP patients was increasing over the past 20 years, with an AAPC of 0.52% (95% CI 0.34-1.39). In subgroup analyses, the proportion of HTG-AP in SAP and MSAP group both increased significantly, with the AAPC of 0.74% (95% CI 0.23-1.24) and 3.12% (95% CI 1.62-4.63), respectively. Furthermore, the proportion of HTG-AP among AP patients has shown an upward trend over the past 20 years with faster speed. The proportion of biliary pancreatitis among AP patients has also shown an upward trend, with the rate of increase gradually slowed. The proportion of alcohol-associated pancreatitis among AP patients has remained stable. Conclusions:Since 2000, the incidence proportion of HTG-AP has significantly increased in China with the rate of increase gradually quicker.

Objective:To investigate the impact of plasmapheresis therapy on the clinical efficacy in predicted severe hypertriglyceridemia-associated acute pancreatitis (HTG-AP) patients.Methods:The clinical data of 500 HTG-AP patients admitted to 36 medical centers across China in the Chinese Acute Pancreatitis Clinical Trials Group-PERFORM database from November 2020 to June 2023 were retrospectively analyzed. Besides the inclusion and exclusion criteria from PERFORM study, patients who had acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score ≥8 or CRP>150 mg/L on admission were included in the final analyses ( n=189). Patients were categorized into the plasmapheresis group ( n=51) and the routine treatment group ( n=138) according to the triglyceride-lowering therapies they received. General data, laboratory findings, AP severity, and clinical outcomes were recorded. Results:Patients undergoing plasmapheresis had higher initial triglyceride levels, APACHEⅡ score, SOFA score, and more organ failure than those receiving routine medical treatment. Results of multivariable logistic regression models showed that the plasmapheresis group, as compared to the routine treatment group, was neither associated with decreased risk of persistent organ failure within 14 days [54.9% (28/51) vs 37.7% (52/138), OR=0.89, 95% CI 0.36-2.21, P=0.810], nor with reduced incidence of organ failure on day 7 [17.7% (9/51) vs 15.9% (22/138), OR=0.60, 95% CI 0.19-1.88, P=0.378]. There was no significant difference on the dynamic changes of serum triglyceride within the first three days of admission ( P=0.108). Conclusions:Early plasmapheresis is not associated with reduced incidence of persistent organ failure in predicted severe HTG-AP patients.

Objective:To assess the safety and feasibility of selectively preserving the first branch of the right gastro-omental artery using bidirectional dissection in laparoscopic pylorus-preserving gastrectomy (LPPG).Methods:In this retrospective analysis, we studied preoperative, intraoperative, postoperative, and follow-up data of 30 patients with early gastric cancer treated in the Department of Gastric Cancer in Zhejiang Cancer Hospital (28 patients), Department of Gastrointestinal Surgery in Jiaxing Second Hospital (one patient) and Department of Gastrointestinal Surgery in Hangzhou Red Cross Hospital (one patient) who had undergone selective preservation of the first branch of the right gastro-omental artery during LPPG. The main variables studied were as follows: (1) intraoperative preservation of the first branch of the right gastro-omental artery; (2) the overall surgical situation; and (3) postoperative small bowel follow-through and endoscopy findings.Results:LPPG with selective preservation of the right gastro-omental artery vascular branch was achieved in all 30 of the study patients. The mean operation time was (244.3±29.3) minutes and the median intraoperative blood loss 50 (20–200) mL. The median tumor diameter was 1.2 (0.5–3.6) cm and an average of 32.3±11.6 lymph nodes were dissected. The overall median number of positive lymph nodes was 0 (0–6), and of No. 6 lymph nodes 5.1±1.5. Postoperative feeding resumed at an average of 5.2±0.5 days and the postoperative hospital stay averaged 8.4±3.4 days. Pathological stages were as follows: T1a (14 cases), T1b (10 cases), and T2 (6 cases). Small bowel follow-through imaging showed good results in 28 patients 5 days post-surgery, the remaining two exhibiting good results 9 days post-surgery. There were no instances of delayed gastric emptying, and only one patient (3.3%) developed intra-abdominal infection (resolved with conservative treatment).Conclusion:Selective preservation of the right gastro-omental artery during laparoscopic early gastric cancer surgery is a safe and feasible procedure for treating early mid-gastric body cancer with pyloric preservation.

ObjectiveTo explore the therapeutic mechanism of Bushen Huoxue prescription from the perspective of bone metabolism by observing the clinical efficacy of this prescription in treating femoral head necrosis (ONFH, syndrome of liver and kidney deficiency) and its influences on bone metabolism indexes: N-terminal propeptide (PINP) and β-collagen degradation product (β-CTX). MethodSixty-six ONFH patients with the syndrome of liver and kidney deficiency in Zhengzhou Traditional Chinese Medicine Hospital of Orthopedics from December 2021 to September 2022 were selected. The patients were randomized into an experimental group and a control group by the parallel control method, with 33 patients in each group. The experimental group received Bushen Huoxue prescription orally, while the control group received Xianlinggubao Capsules orally, with a treatment cycle of 6 months. The visual analogue scale (VAS) score, Harris score, Association Research Circulation Osseous (ARCO) staging, imaging changes, quantitative scores of TCM symptoms, and serum levels of PINP and β-CTX were determined before and after treatment. The occurrence of adverse events and reactions was recorded. ResultThe total response rate in the experimental group was 83.87% (26/31), which was higher than that (68.75%, 22/32) in the control group (Z=-2.096, P<0.05). After treatment, the single and total scores of TCM symptoms, VAS score, and β-CTX level decreased in the two groups (P<0.05). Moreover, the decreases in the scores of hip pain, lower limb mobility, soreness of waist and knees, and lower limb flaccidity, total score of TCM symptoms, VAS score, and β-CTX level in the experimental were larger than those in the control group (P<0.05). After treatment, the imaging results showed no significant improvement in the two groups. The Harris score and PINP level in both groups increased after treatment (P<0.05), and the increases were more obvious in the experimental group than in the control group (P<0.05). No serious adverse event or adverse reaction appeared during the observation period. ConclusionBushen Huoxue prescription can relieve pain and TCM symptoms and improve the hip joint function in treating ONFH patients with the syndrome of liver and kidney deficiency. It can inhibit the development of ONFH, increase PINP, and decrease β-CTX. No obvious side effect appears during the clinical observation period, which shows that Bushen Huoxue prescription has good safety.

Alzheimer's disease is a common central neurodegenerative disease, mainly manifested by cognitive impairment and non-cognitive neuropsychiatric symptoms that severely affect patients' daily life and behavioral functioning. The pathogenesis of Alzheimer's disease is still unclear, and the western medicine currently used to treat Alzheimer's disease is only symptomatic, with a single pathway, limited efficacy, and many side effects. In recent years, with the deepening of research on Alzheimer's disease, the study and application of traditional Chinese medicine (TCM) in the treatment of Alzheimer's disease have gradually increased. Several studies have shown that TCM and its effective components can exert anti-Alzheimer's disease effects by regulating molecular mechanisms such as pathological protein production and aggregation, oxidative stress, neuroinflammation, ferroptosis, mitochondrial dysfunction, neurogenesis and neurotransmission, and brain-gut axis. This paper summarized the research progress of TCM in the treatment of Alzheimer's disease in recent years, so as to provide a reference for further study of the specific mechanism of TCM in the prevention and treatment of Alzheimer's disease and the discovery of effective components of TCM.

Objective:To explore the diagnostic value of thromboelastography (TEG) combined with conventional coagulation test (CCT) for trauma-induced coagulopathy (TIC) in patients with electric burns in the early stage.Methods:This study was a retrospective case series research. From February 2018 to February 2024, the clinical data of 128 electric burn patients and 118 thermal burn patients who met the inclusion criteria and admitted to the Department of Burn Surgery of the Third Affiliated Hospital of Inner Mongolia Medical University were collected, including 224 males and 22 females, aged (38±14) years. The patients were divided into electric burn group (128 cases) and thermal burn group (118 cases) according to their injuries. The incidence of TIC, the indicators of CCT, including prothrombin time, activated partial thromboplastin time, thrombin time, fibrinogen level, D-dimer level, platelet count, and the detection indicators of TEG, including coagulation reaction time, K value, coagulation angle, maximum thrombus amplitude, comprehensive coagulation index, and lysis rate at 30 minutes after maximum amplitude within 8 hours of admission were compared between the two groups of patients. The Kappa test was used to analyze the consistency between CCT and TEG in diagnosing TIC in patients with electric burns in the early stage after burns. The receiver operating characteristic curves of CCT, TEG, and TEG combined with CCT in diagnosing TIC in 128 patients with electric burns were drawn, and the area under the curve (AUC), the maximum Jordan index, and sensitivity and specificity at this time were calculated.Results:The proportion of patients diagnosed with TIC in electric burn group was 19.5% (25/128) within 8 hours of admission, which was significantly higher than 10.2% (12/118) in thermal burn group ( χ2=4.21, P<0.05). Compared with those in thermal burn group, prothrombin time was significantly shortened ( t=-2.32, P<0.05), D-dimer level, fibrinogen level, and platelet count were significantly increased (with Z values of -2.11 and -4.16, respectively, t=4.69, P<0.05), the coagulation reaction time was significantly shortened ( t=-2.51, P<0.05), and the maximum thrombus amplitude and lysis rate at 30 minutes after the maximum amplitude were significantly increased (with t values of 2.50 and 2.10, respectively, P<0.05) in patients in electric burn group within 8 hours of admission. There were no statistically significant differences in the other CCT indicators and TEG detection indicators between the two groups of patients ( P>0.05). The CCT and TEG showed high consistency in the diagnosis of TIC in patients with electric burns in the early stage after burns (Kappa=0.63, P<0.05). The AUCs of TEG combined with CCT, TEG, and CCT in diagnosis of TIC in 128 patients with electric burns were 0.92, 0.84, and 0.77 (with 95% confidence intervals of 0.86-0.97, 0.71-0.97, and 0.71-0.97, respectively), with the maximum Jordan indexes of 0.86, 0.57, and 0.65. At this time, the specificity was 93.7%, 83.2%, and 88.2%, respectively, and the sensitivity was 92.3%, 87.5%, and 76.5%, respectively. Conclusions:Patients with electric burns are in a state of hypercoagulability of coagulation system and hyperfunction of fibrinolysis system in the early stage after burns, and TEG combined with CCT can increase the diagnostic rate of TIC in patients with electric burns.
