Vein graft (VG) failure (VGF) is associated with VG intimal hyperplasia, which is characterized by abnormal accumulation of vascular smooth muscle cells (VSMCs). Most neointimal VSMCs are derived from pre-existing VSMCs via a process of VSMC phenotypic transition, also known as dedifferentiation. There is increasing evidence to suggest that ginger or its bioactive ingredients may block VSMC dedifferentiation, exerting vasoprotective functions; however, the precise mechanisms have not been fully characterized. Therefore, we investigated the effect of ginger on VSMC phenotypic transition in VG remodeling after transplantation. Ginger significantly inhibited neointimal hyperplasia and promoted lumen (L) opening in a 3-month VG, which was primarily achieved by reducing ferroptotic stress. Ferroptotic stress is a pro-ferroptotic state. Contractile VSMCs did not die but instead gained a proliferative capacity and switched to the secretory type, forming neointima (NI) after vein transplantation. Ginger and its two main vasoprotective ingredients (6-gingerol and 6-shogaol) inhibit VSMC dedifferentiation by reducing ferroptotic stress. Network pharmacology analysis revealed that 6-gingerol inhibits ferroptotic stress by targeting P53, while 6-shogaol inhibits ferroptotic stress by targeting 5-lipoxygenase (Alox5), both promoting ferroptosis. Furthermore, both ingredients co-target peroxisome proliferator-activated receptor gamma (PPARγ), decreasing PPARγ-mediated nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 1 (Nox1) expression. Nox1 promotes intracellular reactive oxygen species (ROS) production and directly induces VSMC dedifferentiation. In addition, Nox1 is a ferroptosis-promoting gene that encourages ferroptotic stress production, indirectly leading to VSMC dedifferentiation. Ginger, a natural multi-targeted ferroptotic stress inhibitor, finely and effectively prevents VSMC phenotypic transition and protects against venous injury remodeling.

Objective:To evaluate the long-term efficacy of percutaneous microwave ablation (MWA) therapy for hepatocellular carcinoma.Methods:2054 cases with Barcelona Clinic Liver Cancer (BCLC) stage 0~B at the Fifth Medical Center of the Chinese People's Liberation Army General Hospital from January 2006 to September 2020 were retrospectively collected. All patients were followed up for at least 2 years. The primary endpoint of overall survival and secondary endpoints (tumor-related survival, disease-free survival, and postoperative complications) of patients treated with ultrasound-guided percutaneous MWA were analyzed. Kaplan-Meier method was used for stratified survival rate analysis. Fine-and-Gray competing risk model was used to analyze overall survival.Results:A total of 5 503 HCC nodules [mean tumor diameter (2.6±1.6) cm] underwent 3 908 MWAs between January 2006 and September 2020, with a median follow-up time of 45.6 (24.0 -79.2) months.The technical effectiveness rate of 5 375 tumor nodules was 97.5%. The overall survival rates at 5, 10, and 15-years were 61.6%, 38.8%, and 27.0%, respectively. The tumor-specific survival rates were 67.1%, 47.2%, and 37.7%, respectively. The free tumor survival rates were 25.8%, 15.7%, and 9.9%, respectively. The incidence rate of severe complications was 2.8% (108/3 908). Further analysis showed that the technical effectiveness and survival rate over the passing three time periods from January 2006-2010, 2011-2015, and 2016-September 2020 were significantly increased, with P ?

Objective:To investigate the clinical value of abdominal adipose volume in predicting early tumor recurrence after resection of hepatocellular carcinoma (HCC).Methods:The retrospective case-control study was conducted. The clinicopathological data of 132 HCC patients with tumor diameter ≤5 cm who were admitted to The First Affiliated Hospital of Army Medical University from December 2017 to October 2019 were collected. There were 110 males and 22 females, aged (51±4)years. All patients underwent resection of HCC. Preoperative computer tomography scanning was performed and the visceral and subcutaneous fats of patients were quantified using the Mimics Research 21.0 software. Based on time to postoperative tumor recurrence patients were divided to two categories: early recurrence and non-early recurrence. Observation indicators: (1) consistency analy-sis; (2) analysis of factors influencing early tumor recurrence after resection of HCC and construction of prediction model. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribu-tion were represented as M( Q1,Q3) or M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Consistency analysis was conducted using the intragroup correlation coefficient (ICC) test. Multivariate analysis was performed using the binary Logistic regression model forward method. Independent risk factors influencing early tumor recurrence after resection of HCC were screened. The area under curve (AUC) of receiver operating characteristic (ROC) curve was applied to select the optimal cut-off value to classify high and low risks of recurrence. The Kaplan-Meier method was used to draw survival curve and calculate survival time. The Log-Rank test was used for survival analysis. Results:(1) Consistency analysis. The consistency ICC of abdominal fat parameters of visceral fat volume (VFV), subcutaneous fat volume, visceral fat area, and subcutaneous fat area measured by 2 radiologists were 0.84, 1.00, 0.86, and 0.94, respectively. (2) Analysis of factors influencing early tumor recurr-ence after resection of HCC and construction of prediction model. All 132 patients were followed up after surgery for 662(range, 292-1 111)days. During the follow-up, there were 52 patients with non-early recurrence and 80 patients with early recurrence. Results of multivariate analysis showed that VFV was an independent factor influencing early tumor recurrence after resection of HCC ( odds ratio=4.07, 95% confidence interval as 2.27-7.27, P<0.05). The AUC of ROC curve based on VFV was 0.78 (95% confidence interval as 0.70-0.85), and the sensitivity and specificity were 72.2 % and 77.4 %, respectively. The optimal cut-off value of VFV was 1.255 dm 3, and all 132 patients were divided into the high-risk early postoperative recurrence group of 69 cases with VFV >1.255 dm 3, and the low-risk early postoperative recurrence group of 63 cases with VFV ≤1.255 dm 3. The disease-free survival time of the high-risk early postoperative recurrence group and the low-risk early post-operative recurrence group were 414(193,702)days and 1 047(620,1 219)days, showing a significant difference between them ( χ2=31.17, P<0.05). Conclusions:VFV is an independent factor influen-cing early tumor recurrence of HCC after resection. As a quantitative indicator of abdominal fat, it can predict the prognosis of HCC patients.

Objective To analyze the prognosis and influencing factors in patients with radioiodine-refractory differentiated thyroid cancer (RAIR-DTC). Methods A retrospective analysis was conducted on 52 patients with RAIR-DTC who underwent ineffective ¹³¹I therapy at the Department of Nuclear Medicine, Cancer Hospital, Chinese Academy of Medical Sciences from October 2016 to January 2020. Patients were categorized into progression and stable groups based on disease progression within five years post-treatment. Differences between groups were analyzed using chi-square test and logistic regression. Independent prognostic risk factors were identified using a Cox proportional hazards model. The Kaplan-Meier method with log-rank test was used to evaluate the impact of treatment on the prognosis of the progression group. Results The 3-year and 5-year survival rates of the 52 patients with RAIR-DTC were 88.5% and 73.1%, respectively. In the progression group, the rates were 81.8% and 57.6%. In the stable group, the rates were 100% and 100%. There were significant differences between the two groups in terms of age, presence of extrathyroidal extension, and the initial ¹³¹I treatment dose (P < 0.05). Univariate analysis indicated that the age, pre-ablation stimulated thyroglobulin level before the first ¹³¹I treatment, the neutrophil-to-lymphocyte ratio before the first treatment, and the sites of recurrence and metastasis were significantly associated with overall survival (P < 0.05). Multivariate analysis showed that age > 55 years (HR=12.40, 95% CI= 2.09-73.57, P=0.001) and distant metastasis (HR=24.47, 95% CI=4.17-143.75, P < 0.001) were independent risk factors for poor prognosis. Kaplan-Meier curve analysis showed that local surgery and/or targeted therapy significantly prolonged progression-free survival in the progression group (P < 0.001). Conclusion The prognosis for RAIR-DTC is poor, with advanced age and distant metastasis significantly associated with unfavorable outcomes. In elderly patients and those with extrathyroidal invasion, the treatment dose during initial ¹³¹I therapy may be appropriately increased to delay disease progression. For patients with disease progression, prompt local surgical intervention and/or targeted therapy is recommended.

Uveal melanoma (UM) poses a significant lethality, with approximately 50% of those developing metastases surviving less than one year. In the progression of UM, vasculogenic mimicry (VM) induced by hypoxia plays a pivotal role, which also partially explains the resistance of UM to anti-angiogenic therapies. Nevertheless, the crucial molecular mechanisms underlying VM in the progression of UM remain unclear. We identified ubiquitin conjugating enzyme E2 G2 (UBE2G2) as a critical suppressor through transcriptomic sequencing and metastasis correlation screening. In UM, hypoxia-induced VM and metastasis are markedly exacerbated by UBE2G2 knockdown and significantly alleviated by its overexpression. Mechanistically, UBE2G2 directly binds to galectin 3 binding protein (LGALS3BP) and forms a complex with the E3 ubiquitin ligase tripartite motif containing 38 (TRIM38), facilitating ubiquitination-mediated degradation of LGALS3BP at the K104 residue. Furthermore, UBE2G2 inhibits oncogenic phenotypes by inactivating intracellular PI3K/AKT signaling and reprogramming the tumor microenvironment. Therefore, targeting intercellular and intracellular molecular mechanisms of the hypoxia-UBE2G2-LGALS3BP axis may contribute to developing various therapeutic strategies for UM.

OBJECTIVE To evaluate the effectiveness， safety and economy of baloxavir marboxil in the treatment of influenza， and to provide evidence-based reference for the introduction of new drugs in hospitals and clinical medication decisions. METHODS Retrieved from PubMed， Embase， Web of Science， Cochrane Library， Epistemonikos， CBM， CNKI， VIP， Wanfang database， official websites and relevant databases of health technology assessment （HTA） institutions， the results of the included studies were descriptively analyzed after literature screening， data extraction and quality evaluation. RESULTS A total of 11 studies were included， involving 6 systematic reviews/meta-analyses and 5 pharmacoeconomic studies. Compared with placebo， baloxavir marboxil significantly shortened the time to alleviation of symptoms （TTAS） and time to resolution of fever （TTRF）， reduced the virus titer change from baseline at 24 h and 48 h after treatment and the incidence of bronchitis， with statistical significance （P＜ 0.05）. Compared with neuraminidase inhibitors （NAIs）， there were no significant differences in shortening TTRF and reducing the incidence of complications， pneumonia and bronchitis （P＞0.05）. The majority of studies suggested that there were no significant differences in shortening TTAS （P＞0.05）. Only very low-quality literature suggested that baloxavir marboxil could significantly reduce the virus titer change from baseline at 24 h and 48 h after treatment. In terms of safety， the incidences of adverse events （AEs） and drug-related adverse events （DRAEs） induced by baloxavir marboxil showed no significant differences， compared with peramivir and zanamivir （P＞0.05）. Some studies considered that the incidences of AEs and DRAEs with baloxavir marboxil were lower than placebo， oseltamivir and laninamivir. Compared with oseltamivir in China and laninamivir in Japan， baloxavir marboxil showed cost-effectiveness advantages. CONCLUSIONS Compared with placebo， baloxavir marboxil has good efficacy， safety and economy. Compared with NAIs （oseltamivir）， baloxavir marboxil has good economic advantages in China， but further high-quality studies are still needed regarding its safety and efficacy.

Tyrosine hydroxylase deficiency induced dopa-responsive dystonia is a treatable neurometabolic disease,which is relatively rare in clinic. In this paper,we present a case of dopa-responsive dystonia caused by tyrosine hydroxylase deficiency and reviewed relevant literature to investigate the pathogenesis,clinical manifestations,diagnosis and treatment of dopa-responsive dystonia caused by tyrosine hydroxylase deficiency. Finally,we concluded that peripheral blood prolactin may be a biomarker of tyrosine hydroxylase deficiency,Genetic testing in patients with clinically suspected tyrosine hydroxylase deficiency may be the only way to confirm the diagnosis,and early identification of the diagnosis and levodopa treatment may significantly improve the prognosis.

Clinical data of 43 patients who underwent endoscopic resection for gastrointestinal stromal tumors (GIST) of length ≤1.2 cm at the Digestive Endoscopy Center of the 909th Hospital from January 2016 to December 2018 were retrospectively analyzed. The patients were divided into the endoscopic ligation resection (ELR) group ( n=27) and the endoscopic submucosal excavation (ESE) group ( n=16). The general, perioperative and follow-up data of the two groups were compared. The results showed that there was no significant difference in the general data between the two groups. The operation time was 20.0 (18.0,25.0) min in the ELR group and 27.5 (23.0,37.5) min in the ESE group, showing significant difference ( U=92.5, P=0.001). The en bloc resection rates were 100.0% (27/27) in the ELR group and 81.3% (13/16) in the ESE group, showing significant difference ( P=0.045). The postoperative hospital stays were 3 (2,4) days in the ELR group and 5 (4,6) days in the ESE group, showing significant difference ( U=125.5, P=0.020). There was no significant difference in the intraoperative bleeding rate, intraoperative hemorrhage volume, intraoperative perforation rate, number of hemostatic clips or postoperative complications including hemorrhage, fever and peritonitis between the two groups ( P>0.05). During the follow-up, there was no recurrence or metastasis of GIST in both groups. ELR and ESE can be safe and effective for small GIST ≤1.2 cm in diameter. Compared with the ESE group, the operation time and postoperative hospital stay are shorter with higher en bloc resection rate in the ELR group.
