To thoroughly implement the strategic deployment outlined in the Opinions of the Central Committee of the Communist Party of China and the State Council on Promoting the Inheritance and Innovative Development of Traditional Chinese Medicine regarding research on dominant diseases of traditional Chinese medicine and to uphold the development philosophy of equal emphasis on traditional Chinese medicine and western medicine，the China Association of Chinese Medicine has fully played a leading academic role by systematically organizing and conducting a series of academic youth salons on clinical dominant diseases of traditional Chinese medicine. On September 13，2024，the 36^th Youth Salon on Clinical Dominant Diseases was successfully held in Nanjing，focusing on the advantages of traditional Chinese medicine and the integrative traditional Chinese medicine and western medicine in the diagnosis and treatment of erectile dysfunction （ED）. The conference brought together leading experts from traditional Chinese medicine，western medicine，and interdisciplinary fields，facilitating in-depth multidisciplinary discussions that led to key consensus on optimizing traditional Chinese medicine treatment protocols for ED，researching and developing new drugs of traditional Chinese medicine，and advancing interdisciplinary development in traditional Chinese medicine. This salon systematically sorted out the clinical strengths and distinctive features of traditional Chinese medicine in the diagnosis and treatment of ED. Based on current research foundations and clinical needs，it identified key directions for future scientific layout and scientific research tackling： （1） Standardization of syndrome differentiation system of traditional Chinese medicine for ED. （2） Optimization and standardization of intervention methods of integrated traditional Chinese medicine and western medicine. （3） High-quality clinical research guided by evidence-based medicine. （4） In-depth analysis of the pharmacological mechanisms of traditional Chinese medicine in the treatment of ED. （5） Clinical translation and application promotion of new drugs of traditional Chinese medicine. （6） Interdisciplinary integration and innovation in traditional Chinese medicine. For each research direction，key focus areas，expected objectives，and clinical value were further refined，along with the establishment of a scientifically sound priority funding level evaluation system. Therefore，building on the series of salons on the ED-focused dominant diseases of traditional Chinese medicine，this paper provides standardized guidance for clinical practice of traditional Chinese medicine in ED management，effectively contributing to the high-quality development of traditional Chinese medicine. It serves as a valuable reference for national scientific and technological strategic layout， research and development decision-making in new drugs of traditional Chinese medicine，research topic planning，and clinical guideline formulation.

The application of immunosuppressants has significantly reduced the incidence rate of rejection reaction after liver transplantation， but the clinical efficacy of immunosuppressants is greatly affected by individual differences between patients. This article systematically reviews the recent research advances in the interaction between immunosuppressants and gut microbiota， with a focus on the regulatory role and mechanism of intestinal microflora communities on the efficacy of immunosuppressants. Studies have shown that intestinal microbiome is one of the key factors influencing the efficacy of immunosuppressive therapy after liver transplantation. This review aims to provide a theoretical basis for in-depth research in this field and provide new insights for developing individualized immunosuppressive treatment regimens based on the regulation of intestinal microflora.

Gastric cancer (GC) is characterized by high morbidity and mortality rates. Chinese agarwood comprises the resin-containing wood of Aquilaria sinensis (Lour.) Gilg., traditionally utilized for treating asthma, cardiac ischemia, and tumors. However, comprehensive research regarding its anti-GC effects and underlying mechanisms remains limited. In this study, Chinese agarwood petroleum ether extract (CAPEE) demonstrated potent cytotoxicity against human GC cells, with half maximal inhibitory concentration (IC₅₀) values for AGS, HGC27, and MGC803 cells of 2.89, 2.46, and 2.37 μg·mL^-1, respectively, at 48 h. CAPEE significantly induced apoptosis in these GC cells, with B-cell lymphoma-2 (BCL-2) associated X protein (BAX)/BCL-2 antagonist killer 1 (BAK) likely mediating CAPEE-induced apoptosis. Furthermore, CAPEE induced G₀/G₁ phase cell cycle arrest in human GC cells via activation of the deoxyribonucleic acid (DNA) damage-p21-cyclin D1/cyclin-dependent kinase 4 (CDK4) signaling axis, and increased Fe²⁺, lipid peroxides and reactive oxygen species (ROS) levels, thereby inducing ferroptosis. Ribonucleic acid (RNA) sequencing, real-time quantitative polymerase chain reaction (RT-qPCR), and Western blotting analyses revealed CAPEE-mediated upregulation of heme oxygenase-1 (HO-1) in human GC cells. RNA interference studies demonstrated that HO-1 knockdown reduced CAPEE sensitivity and inhibited CAPEE-induced ferroptosis in human GC cells. Additionally, CAPEE administration exhibited robust in vivo anti-GC activity without significant toxicity in nude mice while inhibiting tumor cell growth and promoting apoptosis in tumor tissues. These findings indicate that CAPEE suppresses human GC cell growth through upregulation of the DNA damage-p21-cyclin D1/CDK4 signaling axis and HO-1-mediated ferroptosis, suggesting its potential as a candidate drug for GC treatment.

Objective: To evaluate the clinical efficacy of a novel autologous blood recovery device during the weaning process from extracorporeal membrane oxygenation (ECMO). Methods: A total of 16 patients who received ECMO support and underwent blood recovery during the weaning process from January 2022 to September 2024 at our hospital were included in the experimental group. In contrast, 58 patients who did not receive blood recovery during the weaning process were assigned to the control group. Transfusion components, costs, and changes in routine blood tests and coagulation functions were compared between the two groups from the day of weaning until 48 hours post-weaning. Results: Significant differences were observed in the volumes of red blood cell transfusions, plasma transfusions, and transfusion costs between the two groups from the day of weaning to 48 hours post-weaning (P<0.05). Additionally, in the experimental group, significant differences were noted in hemoglobin (Hb), platelet (Plt), and activated partial thromboplastin time (APTT) results when comparing values before and after extubation (P<0.05). Conclusion: The application of a novel autologous blood recovery device during ECMO weaning reduces patient costs, minimizes wastage of autologous blood, decreases reliance on exogenous blood transfusions, and mitigates the risks associated with allogeneic blood transfusion. This approach merits further promotion for clinical use.

Objective To investigate the effect of Biejiajian Pill(BJJP)on malignant biological behavior of hepatocellular carcinoma Hep3B cells and its regulatory mechanism.Methods A total of 72 healthy SD rats were randomly divided into blank control(BC)group,low(0.55 g/kg),medium(1.10 g/kg)and high(2.20 g/kg)BJJP experimental group,and drug-containing serum was prepared.Hep3B cells were divided into BC group,normal rat serum treatment(NC)group,low dose BJJP(LBJJP)group,medium dose BJJP(MBJJP)group and high dose BJJP(HBJJP)group,empty plasmid(pcDNA3.1)group,and CKLF-like MARVEL transmembrane domain containing 6(CMTM6)overexpression(pcDNA3.1-CMTM6)group,and the NC+pcDNA3.1 group,MBJJP+pcDNA3.1 group,NC+pcDNA3.1-CMTM6 group and MBJJP+pcDNA3.1-CMTM6 group.The proliferation of hepatoma Hep3B cells was detected by CCK-8.The migration and invasion of hepatoma Hep3B cells were detected by Transwell assay.The expression levels of proliferation-related proteins proliferating cell nuclear antigen(PCNA),epithelial-mesenchymal transition(EMT)related proteins(E-cadherin,N-cadherin and Vimentin),and CMTM6 proteins in hepatoma Hep3B cells were detected by Western blotting experiments.Results Compared with those in BC group,there were no significant differences in the proliferation,migration and invasion abilities of Hep3B cells,or the expression levels of PCNA,EMT related proteins(E-cadherin,N-cadherin and Vimentin)and CMTM6 protein in NC group(P＞0.05).Compared with NC group,LBJJP,MBJJP and HBJJP drug-containing serum inhibited the proliferation,migration and invasion of Hep3B cells,downregulated the protein expression of PCNA;MBJJP and HBJJP upregulated the protein expression of E-cadherin.The protein expressions of N-cadherin,Vimentin and CMTM6 were downregulated,with significant differences(P＜0.05).Compared with pcDNA3.1 group,the protein expression of CMTM6,cell proliferation,migration,invasion,PCNA protein expression,N-cadherin protein expression,and Vimentin protein expression in Hep3B cells in pcDNA3.1-CMTM6 group were significantly upregulated,while the protein expression of E-cadherin was significantly downregulated(P＜0.05).Compared with NC+pcDNA3.1 group,the proliferation,migration and invasion abilities of Hep3B cells in MBJJP+pcDNA3.1 group were decreased,the expression levels of PCNA,Vimentin and N-cadherin protein were decreased,while the expression level of E-cadherin protein was increased.Compared with NC+pcDNA3.1-CMTM6 group,MBJJP+pcDNA3.1-CMTM6 group had the same results in the proliferation,migration and invasion abilities of Hep3B cells and the protein expression levels of PCNA,Vimentin,N-cadherin and E-cadherin.The differences were statistically significant(all P＜0.05).Conclusion BJJP may inhibit the proliferation,migration,invasion and EMT of hepatoma Hep3B cells by regulating the expression of CMTM6.

It was a retrospective study. The propensity score matching was applied to divide the type 2 diabetes mellitus (T2DM) patients who have underwent percutaneous coronary intervention (PCI) into two groups: short-term (<4 weeks) sodium-glucose cotransporter 2 inhibitor (SGLT2i) group (213 patients) and control group (213 patients). The occurrence of contrast-induced acute kidney injury (CIAKI) after PCI was compared between the two groups. The results showed that the incidence of CIAKI in the SGLT2i group was not significantly different from the control group [10.8% (23/213) vs. 7.5% (16/213), χ2=1.383, P=0.313]. The incidence of CIAKI in patients with SGLT2i application time <1 week was higher than that in control patients, but the difference was not statistically significant [13.00% (16/123) vs. 7.5% (16/213), χ2=2.734, P=0.122]. Multivariate logistic regression analysis showed that short-term (<4 weeks) use of SGLT2i would not increase the risk of CIAKI after PCI in T2DM patients ( OR=0.507, 95% CI 0.238-1.077, P=0.077). Short-term application of SGLT2i before PCI may not increase the risk of CIAKI, but it is advisable to avoid initiating the application of SGLT2i before PCI as much as possible.

Objective:To explore the efficacy and safety of the Da Vinci robotic single-port-plus-one technique in common urological surgeries in children.Methods:The data of 59 children who underwent robot-assisted single-port-plus-one laparoscopic surgery from May 2022 to November 2023 in Fuzhou University Affiliated Provincial Hospital were retrospectively analyzed. There were 44 males and 15 females, aged 36 (6, 108)months. Among them, 27 cases had ureteropelvic junction obstruction, with a preoperative anterior-posterior diameter of the renal pelvis of (31.83±6.59) mm. The American Society of Fetal Urology (SFU) grading system revealed grade Ⅲ in 8 sides and grade Ⅳ in 19 sides. Bilateral renal function showed a difference of 13.50% (7.18%, 31.06%). Additionally, 17 cases presented with vesicoureteral reflux. Preoperative voiding cystourethrogram (VCUG) indicated reflux grades Ⅲ, Ⅳ, and Ⅴ in 8, 14, and 4 sides, respectively, with a difference in bilateral renal function of 18.58% (6.04%, 28.30%). Ten cases had obstructive megaureter, with a preoperative renal pelvis diameter of (22.17±7.64)mm and a maximum ureteral diameter of (19.51±3.71)mm. The preoperative bilateral renal function difference was 18.02% (5.23%, 49.42%).Five cases involved duplicated kidney and ureter. Magnetic resonance urography (MRU) confirmed unilateral duplicated kidneys with associated dilatation of the upper renal pelvis and calyces, hydroureter, thin renal cortex in all 5 patients. Among them, 2 cases had ectopic ureteral opening and 1 case had terminal ureteral cyst. Patients with ureteropelvic junction stenosis underwent pyeloplasty, those with vesicoureteral reflux and obstructive megaureter underwent ureteral reimplantation, and patients with duplicated ureters underwent nephrectomy. The Da Vinci robotic surgical system was employed for all procedures. The port placement technique involved a 2-3 cm incision around the navel to insert a single-port four-channel device, followed by the placement of an additional 8 mm operating channel in the left or right abdomen under direct visualization based on the surgical site. Preoperative and postoperative parameters were compared.Results:All operations were successfully completed without conversion to open or laparoscopic surgery. The operation time of the ureteropelvic junction obstruction children was (141.52±22.93) min. The postoperative renal pelvis diameter and bilateral renal function difference were (12.54±4.05) mm and 5.60%(2.14%, 14.48%), respectively, both of which showed significant improvement compared to preoperative levels ( P<0.01). Postoperative hydronephrosis grades were as follows: 13 sides with grade Ⅰ, 13 sides with grade Ⅱ, and 1 side with grade Ⅲ. The operation time of vesicoureteral reflux children was (125.00±11.75) min in the unilateral group and (153.22±14.39) min in the bilateral group. Postoperatively, 2 sides demonstrated reflux grade Ⅰ, 1 side grade Ⅱ, and 1 side grade Ⅲ, indicating improvement compared to preoperative levels. Bilateral renal function difference post-surgery was 13.34% (1.85%, 20.54%), which was more balanced than preoperatively ( P=0.011). Postoperative renal pelvis anterior-posterior diameter and maximum ureteral diameter were reduced to (10.31±3.86) mm and (6.62±2.44) mm, respectively, which were significantly smaller than preoperative measurements ( P<0.01). The bilateral renal function difference post-surgery was 12.04% (4.85%, 47.53%), showing improvement, though not statistically significant ( P=0.508). The operation time of the repeated nephrectomy children was (140.00±12.75) min. No recurrence of preoperative symptoms was noted, and renal cortical function remained generally normal during follow-up. In this study, only 3 cases of obstructive megaureter developed febrile urinary tract infection within 1 month after surgery, and no complications were observed in the remaining cases. Conclusions:This study preliminarily confirmed that the Da Vinci robotic single-port-plus one-port technology can be used in the treatment of common diseases of the urinary system in children. The patients' symptoms were significantly relieved after surgery, and the indicators of hydronephrosis improved compared with those before surgery. The incidence of postoperative complications was low, and aesthetic outcomes of postoperative scars were enhanced. Further studies are needed to assess its long-term efficacy.

Objective To investigate the status of feeding intolerance in patients with enteral nutrition after lung transplantation and analyze its influencing factors,to provide a reference for formulating a reasonable enteral nutrition plan and improving patients'nutritional status.Methods Convenient sampling method was used to retrospectively collect the clinical data of 115 patients who received enteral nutrition support after lung transplantation and were hospitalized in the ICU of a tertiary hospital in Guangdong Province from August 2022 to November 2023.According to the occurrence of feeding intolerance during ICU hospitalization,the patients were divided into a feeding tolerance group and a feeding intolerance group.Univariate and logistic regression analysis were used to analyze the influencing factors of feeding intolerance patients with enteral nutrition after lung transplantation.Results Within 7 days of initiating enteral nutrition,a total of 63 patients developed feeding intolerance,with an incidence of 54.78％.Among them,the incidence of feeding intolerance was relatively high within 1 to 3 days after initiating enteral feeding.The clinical manifestations of feeding intolerance were diarrhea,bloating,gastric retention,vomiting/regurgitation,among which the diarrhea was the highest incidence(87.30％).Logi-stic regression analysis showed that intraoperative net balance volume(OR=0.999),intraoperative blood transfusion(OR=1.001)volume and diabetes history(OR=0.170)were independent influencing factors for feeding intolerance in patients with enteral nutrition after lung transplantation(P＜0.05).Conclusion There was a high incidence of feed-ing intolerance in patients with enteral nutrition after lung transplantation.Patients undergoing lung transplantation who have a high net intraoperative fluid balance,receive a low volume of intraoperative blood transfusions,and have a history of diabetes are at a lower risk of developing feeding intolerance when receiving postoperative enteral nutrition.When starting enteral nutrition,medical staff should dynamically evaluate the risk factors of feeding intolerance,screen high-risk patients as early as possible,and formulate reasonable enteral nutrition programs to improve the nutritional status of patients and promote their rehabilitation.

Objective To observe the effects of Yitangkang on brown fat thermogenesis and mitochondrial biogenesis of PGC1α-NRF1/2-TFAM pathway in db/db mice;To explore its mechanism of regulating glucose and lipid metabolism.Methods Totally 27 six-week-old db/db mice were randomly divided into model group,Yitangkang group(30 g/kg)and liraglutide group(200 μg/kg),another 9 db/m mice of the same age were set as normal group.All groups received intervention with drugs or saline for 6 weeks.The body mass and FBG were measured weekly.After intervention,oral glucose tolerance test(OGTT)was carried out,the contents of serum TC,TG,LDL-C and HDL-C were detected by biochemical analyzer,HE staining was used to observe the morphology of brown adipose tissue(BAT)in scapular region,RT-qPCR and Western blot were used to detect the expressions of UCP1,PRDM16,PGC1α related to BAT thermogenesis and NRF1,Nrf2,TFAM related to mitochondrial biogenesis.Results Compared with the normal group,the body mass,FBG,area under the curve of OGTT and serum TG,TC,LDL-C content of model group significantly increased(P<0.01),the content of HDL-C significantly decreased(P<0.01);the diameter of BAT cells in scapular region was larger,white vacuoles appeared,lipid droplets increased,and the mRNA and protein expressions of UCP1,PRDM16,PGC-1α,NRF1,NRF2 and TFAM in BAT decreased significantly(P<0.01).Compared with the model group,the body mass,FBG,area under the curve of OGTT and serum TG,TC,LDL-C contents of Yitangkang group and liraglutide group significantly decreased(P<0.01),the content of HDL-C increased(P<0.01);BAT cells were smaller in diameter,more closely arranged,more regular in shape,and more abundant in capillary,the mRNA and protein expressions of UCP1,PRDM16,PGC-1α,NRF1,NRF2 and TFAM in BAT increased significantly(P<0.01).Conclusion Yitangkang can regulate mitochondrial biogenesis through PGC1α-NRF1/2-TFAM pathway to activate brown fat in db/db mice and improve glucose and lipid metabolism in db/db mice.

Objective:To investigate how age and nail-tract volumetric bone mineral density (vBMD) are associated with postoperative mechanical performance of proximal femoral nail anti-rotation (PFNA-Ⅱ) fixation for geriatric intertrochanteric fractures using a finite-element analysis.Methods:Fifteen elderly patients with intertrochanteric fracture of the femur were selected for this study. They were 11 females and 4 males and divided into 5 groups based on their ages ( n=3): 55-year-old, 65-year-old, 75-year-old, 85-year-old, and 95-year-old groups. After three-dimensional models of the proximal femur were constructed using the preoperative CT data of their healthy contralateral hip, 31-A1.2 fractures of the AO/OTA type were created and PFNA-Ⅱ fixations simulated. Two loading schemes were created: graded quasi-static axial loads (700 N, 1,400 N, 2,100 N, and 2,800 N) were applied to compute equivalent plastic strain volumes in the femoral head region; displacement-controlled loading was applied to failure to derive load-displacement curves for stiffness and the maximum failure load. Nail-tract vBMD and regional hip vBMDs were measured by quantitative CT. Pearson correlation analysis was conducted to investigate the associations of age and nail-tract vBMD with the aforementioned mechanical indicators. Results:Under the same load, compared with the 55-year-old, 65-year-old, and 75-year-old groups, the plastic strain unit volumes of the fracture models in the 85-year-old and 95-year-old groups increased significantly. Under a load of 700 N, no plastic strain was observed in the fracture models in the 55-year-old, 65-year-old, and 75-year-old groups, while an average plastic strain of approximately 50 mm 3 was observed in the fracture models in the 85-year-old group. Under a load of 2,800 N, the high strain areas in the fracture models in the 85-year-old and 95-year-old groups were mainly concentrated at the tip of the head nail and the junction between the head nail and the main nail. Load-displacement curves showed a marked reduction in the failure load in patients aged ≥85 years. Under loads of 1,400 N, 2,100 N, and 2,800 N, there was a strong association between the nail-tract vBMD and the volume of the plastic strain unit ( r=-0.82, -0.88, -0.89, respectively), which was stronger than those for total-hip vBMD. Conclusions:Finite-element analysis indicates that age and nail-tract vBMD are closely related to local plastic strain and overall stiffness of the proximal femur after PFNA-Ⅱ fixation for the geriatric intertrochanteric fractures. Patients aged ≥85 years old are more prone to plastic yielding, which compromises fixation stability.
