ObjectiveTo evaluate the effects and safety of the optimized new Shengmai Powder （优化新生脉散方） on exercise tolerance in patients with chronic heart failure （CHF） of qi deficiency， blood stasis， and fluid retention syndrome. MethodsA randomized， double-blind， placebo-controlled trial was conducted. A total of 78 CHF patients with qi deficiency， blood stasis， and fluid retention syndrome were recruited and randomly assigned to a treatment group （39 cases） and a control group （39 cases）. On the basis of conventional western medical therapy， patients in the treatment group additionally received the optimized new Shengmai Powder granules， while the control group was given an oral placebo of optimized new Shengmai Powder granules. Patients in both groups took 30.6 g each time， twice a day， mixed with water for administration， with a total treatment course of 4 weeks. The primary outcomes were 6-minute walk distance （6MWD） and peak oxygen uptake （Peak VO₂） measured by cardiopulmonary exercise testing. Secondary outcomes included New York Heart Association （NYHA） functional classification， B-type natriuretic peptide （BNP） levels， cardiac function indexes including left ventricular ejection fraction （LVEF）， left ventri-cular end-systolic diameter （LVESD） and left ventricular end-diastolic diameter （LVEDD）， Minnesota Living with Heart Failure Questionnaire （MLHFQ） scores， and scores of four diagnostic information of traditional Chinese medicine （TCM）. All indicators were assessed once before and after treatment respectively. Safety indicators were evaluated， and adverse events during the trial were recorded. ResultsAll patients in both groups were included in the full ana-lysis set （FAS） and safety set （SS）. Compared with baseline， the 6MWD and Peak VO₂ of cardiopulmonary exercise test in the treatment group significantly increased after treatment， while the MLHFQ scores， serum BNP levels and scores of TCM four diagnostic information significantly decreased， and the NYHA cardiac function grade significantly improved （P＜0.01）. After treatment， the 6MWD and Peak VO₂ of cardiopulmonary exercise test， as well as their changes from baseline in the treatment group were higher than those in the control group； the MLHFQ scores， serum BNP levels and scores of TCM four diagnostic information in the treatment group were lower than those in the control group； and the improvement of NYHA cardiac function grade in the treatment group was superior to that in the control group （P＜0.01）. There was no statistically significant differences in all indicators after treatment in the control group （P＞0.05）. The incidence of adverse events was 5.1% （2/39） in the treatment group and 2.6% （1/39） in the control group， with no statistically significant difference between groups （P＞0.05）. ConclusionOn the basis of conventional western medicine treatment， the addition of the optimized new Shengmai Powder can further improve exercise tolerance， cardiac function and quality of life in patients with CHF of qi deficiency， blood stasis and fluid retention syndrome， and show good safety.

In recent years, research on stem cell therapy in the field of lung transplantation has gradually increased, demonstrating its potential in improving the outcomes of lung transplantation. As a treatment option for end-stage lung diseases, lung transplantation faces challenges such as scarcity of donor organs, postoperative complications and rejection. Stem cells, with their self-renewal and multi-directional differentiation capabilities, have emerged as strong candidates for alternative or adjunctive treatments. Current studies show that embryonic stem cells and umbilical cord mesenchymal stem cells play significant roles in lung tissue regeneration and immune regulation. However, stem cell therapy still needs to overcome issues such as the selection of cell sources, low survival rates after transplantation and unclear long-term efficacy in clinical applications. Future research should focus on exploring new stem cell sources, improving transplantation techniques and establishing efficacy evaluation systems.

Objective:To study the outcomes of the modified Devine + Shiraki surgical approach in the treatment of severe concealed penis.Methods:A retrospective analysis was conducted on the clinical data of initially treated patients with severe concealed penis admitted to the Department of Urology, Henan Provincial People’s Hospital from March 2020 to September 2022. The therapeutic effects of three surgical approaches (Devine, Shiraki, and modified Devine + Shiraki) were analyzed and compared. The Devine approach mainly focuses on eliminating the pathological morphology of the concealed penis, thoroughly releasing the penile shaft, and correcting the concealed state; the Shiraki approach emphasizes the rational distribution of skin flaps; the key of the modified Devine + Shiraki approach lies in combining the advantages of the two approaches, achieving both complete correction of the concealed state and rational distribution of skin flaps. Improvements were made to the conventional surgical sequence: skin flap distribution was pre-designed before correcting the concealed penis to avoid difficulties in skin flap arrangement caused by degloving, thereby preventing postoperative complications such as stricture rings, lymphedema, or erectile pain. Three months after the operation, follow-up was performed to assess incision healing, presence of lymphedema or stricture rings, satisfaction with penile exposure, recurrence of the concealed state, urination patency, presence of urethral injury, and normal erectile function. A patient satisfaction survey was conducted 6 months after the operation. Measurement data with normal distribution were expressed as Mean± SD, and one-way analysis of variance was used for comparison among the three groups; categorical variables were expressed as case numbers and percentages, and chi-square test was used for comparison among the three groups. Results:Eighty, fifty, and forty-five male children were enrolled in the Devine + Shiraki group, Devine group, and Shiraki group, respectively. There were no statistically significant differences in age and body mass index (BMI) among the three groups [age: (7.6±4.5) years vs. (7.2±4.4) years vs. (6.7±4.2) years, F=0.61, P=0.546; BMI: (17.4±3.1) kg/m 2 vs. (17.7±3.2) kg/m 2 vs. (18.0±3.3) kg/m 2,F=0.57, P=0.565]. During surgery, all concealed penile shafts were completely released, and the penile skin was rationally distributed. The postoperative follow-up period ranged from 3 months to 18 months, with an average follow-up time of 13.6 months. At the 3-month postoperative follow-up, all three groups showed satisfactory wound healing with no signs of infection or skin flap necrosis; penile skin coverage was adequate, and all children demonstrated unobstructed urination without evidence of urethral injury; normal erectile function was preserved in all cases, with no reports of erectile dysfunction or pain. The recurrence rate of the concealed penis in the Devine + Shiraki group was significantly lower than that in the Devine group and Shiraki group, with a statistically significant difference [0 (0/80) vs. 6.0% (3/50) vs. 31.1% (14/45), χ2=32.88, P<0.001]; the proportion of patients without postoperative lymphedema and stricture rings in the Devine + Shiraki group was higher than that in the Devine group and Shiraki group, with a statistically significant difference [97.5% (78/80) vs. 70.0% (35/50) vs. 86.7% (39/45), χ2=20.39, P<0.001]. The Devine+ Shiraki, Devine, and Shiraki groups reported postoperative satisfaction in 76 (95.0%), 35 (70.0%), and 31 (68.9%) cases, respectively. Conclusion:The modified Devine + Shiraki surgical approach has definite efficacy, good safety, and a low incidence of complications, and can be used as an option for the treatment of severe concealed penis.

Esophageal squamous cell carcinoma(ESCC)has a poor prognosis,and its invasion and metastasis are the main cause of decreased patients'quality of life and survival rate.The invasion and metastasis of ESCC involve multiple mechanisms,including extracellular matrix degradation,epithelial-mesenchymal transition(EMT),and tumor angiogenesis,accompanied by molecular abnormalities at multiple levels,such as non-coding RNAs,EMT-related proteins,matrix metalloproteinases,vascular endothelial growth factor,exosomes,and circulating tumor cells.Predicting the risk of ESCC invasion and metastasis and implementing active interventions are crucial for effective treatment of ESCC and improvement of patients'quality of life and survival rate.This article reviewed the research progress on molecular markers related to invasion and metastasis of ESCC,aiming to provide insights for the early diagnosis and treatment of ESCC.

Background and Aims:Acute pancreatitis(AP)is an acute inflammatory disease of the pancreas caused by abnormal activation of pancreatic enzymes.Although gallstones,hyperlipidemia,and alcohol use are the most common causes,a subset of patients develop AP secondary to rare etiologies that are often misdiagnosed or diagnosed late,leading to recurrence or inappropriate management.This study aims to summarize the clinical characteristics,diagnostic strategies,and treatment outcomes of four cases of AP caused by uncommon etiologies,supported by a literature review.Methods:Clinical data of 4 patients admitted to the Department of Hepatobiliary and Pancreatic Surgery,the Third Xiangya Hospital of Central South University,between November 2021 and September 2024,were retrospectively analyzed.Their etiological characteristics,diagnostic approaches,and treatment strategies were reviewed in combination with relevant literature.Results:The underlying causes of AP were intraductal papillary mucinous neoplasm,pancreatic neuroendocrine tumor,pancreatic ductal adenocarcinoma,and duodenojejunal intussusception.All cases initially presented as idiopathic AP.Three patients underwent definitive surgical treatment and recovered well,while one patient with pancreatic cancer received only palliative care due to delayed diagnosis and died three months later.Conclusion:AP secondary to rare etiologies often mimics common forms in clinical presentation but poses diagnostic challenges.For patients with recurrent or idiopathic AP,clinicians should emphasize etiological tracing and utilize advanced imaging and endoscopic modalities for early identification.Timely etiological intervention,particularly surgical management when appropriate,is essential for preventing recurrence and improving prognosis.

Background and purpose:Internal mammary sentinel lymph node biopsy(IMSLNB)is a minimally invasive diagnostic technique for regional lymph nodes in breast cancer,which can provide accurate lymph staging and guide adjuvant treatment decision,but its clinical application has been controversial.The purpose of this study was to investigate the prognosis of IMSLNB in early breast cancer.Methods:In this study,a retrospective cohort of 7 949 patients with breast cancer from January 1,2016 to December 31,2021 was analyzed.After applying propensity score matching,the patients were divided into IMSLNB group and no-IMSLNB group,and the regional recurrence-free survival(RRFS),local recurrence-free survival(LRFS),distant metastasis-free survival(DMFS),disease-free survival(DFS)and overall survival(OS)of the two groups were compared.This study was approved by the Clinical Research Ethics Committee of the Affiliated Tumor Hospital of Shandong First Medical University(approval number:SDTHEC20130324).Results:A total of 990 patients were included in the final analysis(330 in the IMSLNB group and 660 in the no-IMSLNB group).IMSLN metastasis was found in 54 patients in the IMSLNB group,including 47 patients with axillary lymph node(ALN)metastasis and 7 patients with IMSLN metastasis only.The IMSLN transfer rate was 16.4%.The median follow-up of 41 months showed that the IMSLNB group demonstrated better 3-year DFS[98.4%vs 94.2%,hazard ratio(HR)=0.509;95%CI:0.312-0.828,P=0.007]and 5-year DFS(92.5%vs 87.3%,HR=0.214,95%CI:0.206-0.222,P=0.011)compared with no-IMSLNB group.However,no significant differences were observed in 3-year OS(99.1%vs 99.4%,HR=0.618,95%CI:0.231-1.655,P=0.338)or 5-year OS(98.5%vs 99.1%,HR=0.52,95%CI:0.51-0.53,P=0.392)between the two groups.The 3-year RRFS in the IMSLNB group was better compared with the no-IMSLNB group(99.09%vs 97.73%,HR=0.066;95%CI:0.061-0.071,P=0.048),while no significant differences were observed in 3-year LRFS(99.70%vs 98.19%,HR=0.209;95%CI:0.201-0.217,P=0.130)or DMFS(95.76%vs 96.06%,HR=0.865,95%CI:0.858-0.872,P=0.820)between the two groups.The exploratory subgroup analysis of DFS revealed that patients in the following subgroups could significantly benefit from IM-SLNB(P＜0.05):diagnosis age(≤50 years),premenopausal status,BMI(≤24),lymphovascular invasion(LVI,present),tumor location(lateral),molecular subtype[hormone receptor positive(HR+)/human epidermal growth factor receptor 2 negative(HER2-)],histological type(invasive ductal carcinoma),and axillary lymph node status(positive).Conclusion:IMSLNB can provide more accurate regional lymph node staging for early breast cancer,help optimize adjuvant radiotherapy strategies,and improve patients'DFS and RRFS.It can be promoted as a minimally invasive staging technique for regional lymph nodes.
