Objective To evaluate the impact of an integrated management mode of prenatal diagnosis-postnatal treatment for congenital heart disease (CHD) on perioperative and long-term outcomes of the arterial switch operation (ASO), and to analyze the efficacy of ASO in a single center. Methods This retrospective study analyzed the clinical data of 183 children who underwent ASO at Guangdong Provincial People’s Hospital from 2018 to 2024. The cohort included 106 (57.9%) patients of transposition of the great arteries with intact ventricular septum (TGA/IVS), 61 (33.3%) patients of transposition of the great arteries with ventricular septal defect (TGA/VSD), and 16 (8.7%) patients of Taussig-bing anomaly (TBA). Perioperative indicators were compared between 91 patients in the prenatal-postnatal integrated management group (an integrated group) and 92 patients in the traditional management group (a non-integrated group). Long-term survival and reoperation rates were analyzed using Kaplan-Meier curves. Results The overall perioperative mortality rate was 4.9% (9/183), showing a downward trend year by year. The primary cause of perioperative mortality was low cardiac output syndrome (LCOS), which occurred in 12 patients (6.6% incidence) with a mortality rate of 75.0%. The integrated group had a higher proportion of males (89.0% vs. 72.8%, P<0.05) and lower body weight [3.1 (2.7, 3.3) kg vs. 3.3 (3.0, 3.7) kg, P<0.05] compared to the non-integrated group. The age at surgery was significantly earlier in the integrated group [7 (3, 10) d vs. 14 (9, 48) d, P<0.05], and all children in the integrated group underwent ASO within the optimal surgical window (100.0% vs. 82.6%, P<0.05). Intraoperatively, cardiopulmonary bypass time [173 (150, 207) min vs. 186 (159, 237) min, P<0.05] and aortic cross-clamp time [100 (90, 117) min vs. 116 (97, 142) min, P<0.05] were significantly shorter in the integrated group. Although the integrated group had longer postoperative mechanical ventilation time [145 (98, 214) h vs. 116 (77, 147) h, P<0.05] and higher 48-hour maximum vasoactive inotropic score [15 (10, 21) points vs. 12 (8, 16) points, P<0.05], there was no statistically significant difference in the incidence of severe complications (LCOS, necrotizing enterocolitis, extracorporeal membrane oxygenation) or mortality rate (3.3% vs. 6.5%, P=0.51) between the two groups, despite earlier surgical intervention and a higher proportion of critically ill cases in the integrated group. The length of hospital stay in the emergency surgery group was significantly shorter than that in the elective surgery group [20 (15, 28) d vs. 25 (21, 30) d, P<0.05], suggesting that early surgery may be of potential benefit. A total of 163 patients were successfully followed up for a median of 4.7 years, with a 5-year survival rate of 95.1% and a freedom from reintervention survival rate of 95.1%. There were no late deaths, and the most common postoperative complication was pulmonary artery stenosis. Conclusion The integrated management model allowed critically ill children with lower body weights to safely undergo surgery, significantly optimizing the timing of surgery and shortening intraoperative times. The long-term risk of reoperation after ASO is primarily concentrated on pulmonary artery stenosis, necessitating long-term follow-up and monitoring.

Chronic glomerulonephritis （CGN） is a common clinical chronic glomerular disease caused by autoimmune reaction， the pathogenesis of which is complex and has not been fully elucidated. There is no specific treatment method in modern medicine. The establishment of an animal model of CGN in accordance with its characteristics in western medicine and traditional Chinese medicine will help to reveal the pathogenesis of CGN， rate drugs， and improve the treatment plan. Based on the clinical diagnostic criteria of CGN， the paper establishes the syndrome differentiation criteria of CGN for Chinese and western medicine. Through summarizing the literature on animal models of CGN and making a further analysis， it is found that the CGN models are mainly modeled using rats with the methods of single-factor induction or two-factor induction， and the main manifestation of the disease characteristics is nephritis-related symptoms. The single-factor-induced or two-factor-induced CGN rat models have a high fitting degree with the clinical characteristics in western medicine， but the fitting degree is insufficient with the clinical characteristics in traditional Chinese medicine. In addition， the CGN models with syndromes of traditional Chinese medicine are dominated by Qi deficiency in the spleen and kidney and Qi deficiency in the lung and kidney， while models for Yang deficiency in the spleen and kidney， Yin deficiency in the liver and kidney， and deficiency of both Qi and Yin are slightly insufficient. Therefore， it is important to prepare a new and improved animal model of CGN， so that a preclinical model can be provided for the exploration of the pathogenesis of CGN in western medicine and traditional Chinese medicine and its therapeutic research.

ObjectiveTo develop a nomogram-based risk prediction model for chronic obstructive pulmonary disease (COPD) incidence among the community-dwelling population aged 40 years old and above, so as to provide targeted references for the screening and prevention of COPD. MethodsBased on a natural population cohort in suburban Shanghai, a total of 3 381 randomly selected participants aged ≥40 years underwent pulmonary function tests between July and October 2021. Cox stepwise regression analysis was used to develop overall and gender-specific risk prediction models, along with the construction of corresponding risk nomograms. Model predictive performance was evaluated using the C-indice, area under the curve (AUC) values, and Brier score. Stability was assessed through 10-fold cross-validation and sensitivity analysis. ResultsA total of 3 019 participants were included, with a median follow-up duration of 4.6 years. The COPD incidence density was 17.22 per 1 000 person-years, significantly higher in males (32.04/1 000 person-years) than that in females (7.38/1 000 person-years) (P<0.001). The overall risk prediction model included the variables such as gender, age, education level, BMI, smoking, passive smoking, and respiratory comorbidities. The male-specific model incorporated the variables such as age, BMI, respiratory comorbidities, and smoking, while the female-specific model included age, marital status, respiratory comorbidities, and pulmonary tuberculosis history. The C-indices for the overall, male-specific, and female-specific models were 0.829, 0.749, and 0.807, respectively. The 5-year AUC values were 0.785, 0.658, and 0.811, with Brier scores of 0.103, 0.176, and 0.059, respectively. Both 10-fold cross-validated C-indices and sensitivity analysis (excluding participants with a follow-up duration of <6 months) yielded C-indices were above 0.740. ConclusionThis study developed concise and practical overall and gender-specific COPD risk prediction models and corresponding nomograms. The models demonstrated robust performance in predicting COPD incidence, providing a valuable reference for identifying high-risk populations and formulating targeted screening and personalized management strategies.

Myocardial ischemia-reperfusion injury （MIRI） is one of the major complications of cardiovascular diseases in recent years， seriously threatening the life and health of patients. In recent years， although significant progress has been made in modern medical research on MIRI， due to its complex pathogenesis， adverse drug reactions， and high postoperative risks， there is an urgent need for safer and more effective therapeutic drugs. The pathological effects of MIRI involve inflammatory responses， oxidative stress， apoptosis， and other mechanisms， while Chinese medicine polysaccharide compounds exhibit pharmacological effects such as anti-inflammation， antioxidation， and anti-apoptosis， which are of great significance for improving MIRI. Numerous studies have found that Chinese medicine polysaccharide compounds mainly exert their effects by activating signal pathways such as nerve regenerative factor-1/epidermal growth factor receptor （NRG-1/ErbB）， phosphatidylinositol-3-kinase/protein kinase B （PI3K/Akt）， nuclear factor E₂-related factor 2/heme oxygenase-1 （Nrf2/HO-1）， adenosine 5ʹ-monophosphate-activated protein kinase/silent information regulator 1/peroxisome proliferators-activated receptor γ coactivator lα （AMPK/SIRT1/PGC1α）， Ras homologous gene/Rho kinase （Rho/ROCK）， glycogen synthase kinase 3 （GSK-3）， and P38 mitogen-activated protein kinase （p38-MAPK）， thereby playing a role in improving MIRI. This paper， based on an extensive review of relevant literature in China and abroad， systematically summarizes the latest research findings on the use of Chinese medicine polysaccharide compounds in the treatment of MIRI， analyzes the mechanisms by which these compounds improve MIRI， and explores new therapeutic directions based on the joint investigation of signaling pathways and metabolomics. The paper emphasizes the importance of interdisciplinary cooperation in promoting the development of new drugs， aiming to provide valuable references for the basic research and clinical application of Chinese medicine polysaccharide compounds， ultimately benefiting the majority of cardiovascular disease patients.

ObjectiveTo establish the specific chromatogram and quantitative analysis of multi-components by single-marker（QAMS） based on linear calibration using two reference substances（LCTRS）， explore the consistency between Hedyotis Herba dispensing granules and standard decoction， and evaluate the quality of the dispensing granules. MethodsHigh performance liquid chromatography（HPLC） specific chromatogram was established based on 15 batches of Hedyotis Herba standard decoction and 10 batches of the dispensing granules， and LCTRS was used to locate chromatographic peaks. The actual retention times of 7 characteristic peaks in the specific chromatogram was measured on 24 different types of C₁₈ columns， taking deacetyl asperulosidic acid and asperulosidic acid as the dual standard compounds， the retention times of the other 5 characteristic peaks were predicted and validated. Based on this， QAMS was developed to determine the contents of four components（deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester， asperulosidic acid， and p-coumaric acid）. Then， the relative correction factors of deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester and p-coumaric acid were calculated using the reference peak of asperulosidic acid in the dual standard compounds， and each component was quantified accordingly. Finally， the consistency between the dispensing granules and standard decoction was assessed by taking extract rate of the standard decoction， consistency of the specific chromatograms， contents and transfer rates of the indicator components as indexes， and the quality of the dispensing granules was evaluated. ResultsThere were 7 common peaks in the characteristic chromatogram of samples of Hedyotis Herba standard decoction and the dispensing granules， and four of them were identified by reference standards， namely deacetyl asperulosidic acid（peak 1）， deacetyl asperulosidic acid methyl ester（peak 3）， asperulosidic acid（peak 6） and p-coumaric acid（peak 7）. The similarity between the dispensing granules and the standard decoction was >0.9. The absolute deviation in the predicted retention time for each component by LCTRS was lower than that of the relative retention time method. The extract rate of the 15 batches of Hedyotis Herba standard decoction ranged from 7.89% to 14.60%， the contents of deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester， asperulosidic acid and p-coumaric acid were 6.62-19.70， 3.83-17.99， 1.57-6.69， 1.62-4.52 mg·g^-1， and the transfer rates of these components from decoction pieces to the standard decoction were 22.89%-39.60%， 34.03%-62.24%， 24.25%-43.70%， and 40.58%-73.71%， respectively. The extract rate， index component contents and transfer rates from decoction pieces to the three batches of Hedyotis Herba dispensing granules（P1-P3）， produced by manufacturer A， were similar to those of the standard decoction prepared from the same batch of decoction pieces， and all fell within the specified range. The contents of the 4 indicator components in 7 batches of the dispensing granules（P4-P10） from manufacturers B-E were all within the range of the content converted from the standard decoction based on the quantity of the dispensing granules. ConclusionThe established specific chromatogram and QAMS based on LCTRS are reasonable and reliable. Based on the evaluation indicators of standard decoction yield， consistency of specific chromatograms， contents and transfer rates of the four index components， the 10 batches of Hedyotis Herba dispensing granules from various manufacturers have exhibited good consistency with the standard decoction， indicating that the current production process is relatively reasonable.

Cerebral ischemia-reperfusion injury （CIRI）， a common cerebrovascular disease damage， has garnered increasing attention in the treatment of acute ischemic stroke. Restoration of blood flow and reperfusion to ischemic brain tissue is the key to treatment， while this process often triggers a variety of complex pathophysiological responses， such as oxidative stress， apoptosis， inflammation， mitochondrial dysfunction， angiogenic abnormalities， and disruption of the blood-brain barrier. These responses not only impede the recovery of neurological functions but also may lead to damage or even death of nerve cells， seriously affecting the neurological function and quality of survival of patients. As an important transcription factor， nuclear factor E₂-related factor 2 （Nrf2） has the pharmacological effect of alleviating CIRI by regulating antioxidant， anti-apoptosis， anti-inflammation， mitochondrial function， angiogenesis， and blood-brain barrier pathways. This reveals the potential mechanism of traditional Chinese medicine （TCM） in intervening in CIRI and shows the potential of Nrf2 as a new pathway for dealing with ischemia stroke. This paper comprehensively analyzes the effects and mechanisms of active components and compound prescription of TCM in treating CIRI by modulating the Nrf2 signaling pathway， while pointing out the shortcomings of available studies and proposing a multidimensional exploration. This review aims to provide patients with more comprehensive， safe， and effective therapeutic regimens and improve the quality of survival and prognosis of patients. In addition， in-depth research on TCM should be promoted to reveal the potential mechanism for treating CIRI， providing new ideas and directions for the development of novel therapeutic drugs and methods.

HDAC7, a member of class IIa HDACs, plays a pivotal regulatory role in tumor, immune, fibrosis, and angiogenesis, rendering it a potential therapeutic target. Nevertheless, due to the high similarity in the enzyme active sites of class IIa HDACs, inhibitors encounter challenges in discerning differences among them. Furthermore, the substitution of key residue in the active pocket of class IIa HDACs renders them pseudo-enzymes, leading to a limited impact of enzymatic inhibitors on their function. In this study, proteolysis targeting chimera (PROTAC) technology was employed to develop HDAC7 drugs. We developed an exceedingly selective HDAC7 PROTAC degrader B14 which showcased superior inhibitory effects on cell proliferation compared to TMP269 in various diffuse large B cell lymphoma (DLBCL) and acute myeloid leukemia (AML) cells. Subsequent investigations unveiled that B14 disrupts BCL6 forming a transcriptional inhibition complex by degrading HDAC7, thereby exerting proliferative inhibition in DLBCL. Our study broadened the understanding of the non-enzymatic functions of HDAC7 and underscored the importance of HDAC7 in the treatment of hematologic malignancies, particularly in DLBCL and AML.

Objective To compare the differences in the average transaction costs per-referral patients under different models of Integrated Delivery Systems(IDS).Methods Using a typical case sampling method,it selected referred patients from three IDS models:the county medical alliance in D City(Qinghai Province),the urban medical consortium in J District(Zhengzhou City,Henan Province),and the health management coalition in N County(Shandong Province).Structured questionnaires collected demographics,average transaction costs per-referral and cost perceptions.t-tests and ANOVA assessed cost differences;generalized linear regression identified influencing factors.Results Among 915 patients,the average transaction costs per-referral were 1 035.05 yuan(county alliance),195.31 yuan(urban consortium),and 700.97 yuan(health management coalition),with statistically significant differences(P＜0.05).The urban consortium exhibited lower time costs and specialized input costs.Key influencing factors included older age(county alliance),education level,employment status,and referral travel time(urban consortium),as well as urban-rural disparities(health management coalition).Patients'cost perceptions significantly differed across models(P＜0.05).Conclusion The urban medical consortium demonstrated the lowest patient the average transaction costs,highlighting its institutional advantage in minimizing financial burdens.

Objective:This study aimed to clarify clinicopathologic characteristics, postoperative complications, and related risk factors of elderly patients with gastric cancer.Methods:A total of 395 patients(≥65 years old)who underwent radical gastrectomy for gastric cancer in Beijing Hospital from January 2014 to December 2021 were enrolled in this study.The patients were divided into the common elderly group(age<80 years, n=340)and the high-age group(age ≥ 80 years, n=55). Postoperative complications were classified into medical and surgical types.The clinicopathological characteristics and complications were compared between the two groups.Logistic regression models(univariate and multivariate)were used to identify the risk factors for postoperative complications.Results:The common elderly group was 65-79 years old(mean age: 71.5±4.3 years), with 263 male(77.4%); The high-age group was 80-89 years old(mean age: 82.6±2.6 years), with 42 male(76.4%). The comorbidity rate and the number of comorbidities in the high-age group were significantly higher than those in the common elderly group.The American Society of Anesthesiologists(ASA)scores and nutritional risk screening(NRS)2002 scores in the high-age group were significantly higher than those in the common elderly group(both P<0.05), and the activities of daily living(ADL)scores in the high-age group were significantly lower than that in the common elderly group( P<0.001). There were no statistically significant differences in tumor location, degree of differentiation, pathological type, T stage, and N stage between the two groups(all P>0.05). The overall postoperative complication rate in the high-age group was significantly higher than that in the common elderly group(38.2% vs.24.7%, P=0.036); the medical complications were significantly increased in the high-age group(21.8% vs.10.9%, P=0.022), whereas the surgical complications did not increase significantly(25.5% vs.17.1%, P=0.135). Multivariate analysis revealed that the number of comorbidities ≥2( HR=2.502, 95% CI: 1.275-4.911, P=0.008), preoperative NRS 2002 scores ≥5( HR=2.714, 95% CI1.294-5.693, P=0.008), and preoperative ADL scores<100( HR=2.012, 95% CI1.010-4.009, P=0.047)were independent risk factors for medical complications.Additionally, ASA grade ≥ 3( HR=2.586, 95% CI: 1.444-4.632, P=0.001)and proximal or distal gastrectomy( HR=2.397, 95% CI: 1.237-4.574, P=0.009)were independent risk factors for surgical complications. Conclusions:The occurrence of postoperative medical complications in very elderly patients with gastric cancer undergoing radical surgery has increased, while the rate of surgical complications has not increased.Moreover, advanced age itself is not an independent risk factor for postoperative complications.More attention should be paid to medical complications, and the management of commodities and nutritional support should be strengthened during the perioperative period.
