We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Renal interstitial fibrosis (RIF) is the crucial pathway in chronic kidney disease (CKD) leading to the end-stage renal failure. However, the underlying mechanism of Shen Qi Wan (SQW) on RIF is not fully understood. In the current study, we investigated the role of Aquaporin 1 (AQP1) in SQW on tubular epithelial-to-mesenchymal transition (EMT). A RIF mouse model induced by adenine and a TGF-β1-stimulated HK-2 cell model were etablished to explore the involvement of AQP 1 in the protective effect of SQW on EMT in vitro and in vivo. Subsequently, the molecular mechanism of SQW on EMT was explored in HK-2 cells with AQP1 knockdown. The results indicated that SQW alleviated kidney injury and renal collagen deposition in the kidneys of mice induced by adenine, increased the protein expression of E-cadherin and AQP1 expression, and decreased the expression of vimentin and α-smooth muscle actin (α-SMA). Similarly, treatmement with SQW-containing serum significantly halted EMT process in TGF-β1 stimulated HK-2 cells. The expression of snail and slug was significantly upregulated in HK-2 cells after knockdown of AQP1. AQP1 knockdown also increased the mRNA expression of vimentin and α-SMA, and decreased the expression of E-cadherin. The protein expression of vimentin increased, while the expression of E-cadherin and CK-18 significantly decreased after AQP1 knockdown in HK-2 cells. These results revealed that AQP1 knockdown promoted EMT. Furthermore, AQP1 knockdown abolished the protective effect of SQW-containing serum on EMT in HK-2 cells. In sum, SQW attentuates EMT process in RIF through upregulation of the expression of AQP1.

Objective:To evaluate the left ventricular myocardial strain and mechanical synchrony in patients suspected of non-ST-segment elevation acute coronary syndrome (NSTE-ACS) by two-dimensional speckle tracking imaging (2D-STI) and real-time three-dimensional echocardiography (RT-3DE), and to investigate the value of combined echocadiographic parameters in predication of significant coronary artery stenosis.Methods:A total of 95 patients suspected of NSTE-ACS, definitely planed to run coronary angiography (CAG) within 24-72 hours of admission were recruited in the Department of Cardiology, General Hospital of the Southern Theatre Command, PLA from December 2020 to June 2021. Regular echocardiography exam, 2D-STI and RT-3DE were performed prior to CAG.Global longitudinal peak strain (GLPS), territorial longitudinal peak strain (T RCALPS, T LADLPS, T LCXLPS) were computed by 2D-STI; the maximal difference of time to minimal systolic volume of 16-segments (Tmsv16-Dif), standard deviation of time to minimal systolic volume of 16-segment (Tmsv16-SD) and heart rate adjusted standard deviation of time to minimal systolic volume of 16-segment (Tmsv16-SD/R-R) were obtained by RT-3DE. The patients were divided into two groups according to the degree of coronary stenosis.Significant coronary artery stenosis group was defined as ≥70% of left main or any other main branch luminal narrowing ( n=53), non-significant coronary artery stenosis group was defined as <70% of luminal narrowing ( n=42). The differences of general clinical features, left ventricular strain and mechanical synchronization parameters between the two groups were compared. A binary logistic regression model was established to draw the ROC curve for predicting the severity of coronary stenosis by single and combined ultrasound parameters, and calculate the area under the ROC curve (AUC). Results:Compared with non-significant coronary artery stenosis group, GLPS were significantly reduced, while Tmsv16-SD, Tmsv16-Dif and Tmsv16-SD/R-R were significantly increased in sginificant coronary artery stenosis group (all P<0.05). The AUC of GLPS and Tmsv16-SD, Tmsv16-Dif and Tmsv16-SD/R-R for predicting significant coronary stenosis in suspected NSTE-ACS patients were 0.78, 0.69, 0.71 and 0.67, respectively. The result of joint test analysis for the dignosis of NSTE-ACS suspected significant coronary stenosis were as follows: the specificity of tandem test was 90.5%; the sensitivity of parallel test was 83.0%; the sensitivity, specificity and AUC of GLPS-Tmsv16-Dif joint index prediction test were 90.7%, 60.1% and 0.82 (95% CI=0.73-0.89) with 0.508 as Youden index. Conclusions:NSTE-ACS suspected patients with significant coronary stenosis are often accompanied by impaired left ventricular myocardial strain and mechanical dyssynchrony. A simple combination of left ventricular myocardial strain and contractility synchronization improves noninvasive prediction of high-risk coronary artery stenosis in suspected NSTE-ACS, which maybe helpful for screening patients requiring invasive examination.

Objective:To screen biomarkers related to the prognosis of gastric cancer and the efficacy of 5-fluorouracil based on the bioinformatics method.Methods:Gastric cancer datasets like GSE54129, GSE79973 and GSE51725 based on GPL570 platform were downloaded from Gene Expression Omnibus (GEO) database. Genes related to the overall survival (OS) of the top 500 gastric cancer patients were downloaded from GEPIA2 online gene expression profile.GEO2R was used to identify the differentially expressed genes (DEG) between gastric cancer tissues and adjacent normal tissues, STRING database was used to build protein-protein interaction networks (PPI) and to identify the key genes, the enrichment analysis of gene ontology (GO)and Kyoto Encyclopedia of Genes and Genomes (KEGG) was made by using OmicShare. Kaplan-Meier Plotter was used to calculate the value of key genes in predicting the OS of gastric cancer patients. All patients were divided into the high expression group and low expression group according to the optimal cut-off value of gene expression level.Results:A total of 59 DEG were screened, including 39 up-regulated genes and 20 down-regulated genes. The key up-regulated genes including homeodomain transcription factors 2(PITX2), hepatocyte growth factor (HGF), fibroblast growth factor 1 (FGF1), transforming growth factor β 2 (TGFB2), thromobospondin 1 (THBS1) were analyzed by using PPI. Survival analysis results showed that the OS of gastric cancer patients with low expression of FGF1, HGF, PITX2 and TGFB2 genes was better (all P < 0.01); the OS of gastric cancer patients with low expression of THBS1 gene was poor, while the difference was not statistically significant ( P > 0.05). The patients with low expression of RIEG1 gene who received 5-fluorouracil-based chemotherapy regimen had the better OS ( P < 0.01),while those with THBS1 and HGF low expression had the worse OS ( P < 0.05). It was found that key genes might promote the development of gastric cancer by participating in the regulation of TGF- β signaling pathway, Rap1 signaling pathway, MAPK signaling pathway, PI3K-Akt signaling pathway, Hippo signaling pathway, Ras signaling pathway and focal adhesion pathway. Conclusions:Bioinformatics analysis shows that the expressions of FGF1, HGF, PITX2 and TGFB2 genes are related to the prognosis of gastric cancer, and the expressions of RIEG1, THBS1 and HGF are related to the efficacy of 5-fluorouracil, which may be used as a predictive marker of fluorouracil chemosensitivity in patients with gastric cancer.

Objective To preliminarily investigate the safety and feasibility of intra-arterial cold saline infusion combined with intravascular reperfusion for acute ischemic stroke with large artery occlusion. Methods From March 2016 to March 2018, consecutive acute ischemic stroke patients with large artery occlusion within 8 h after onset admitted to the Department of Neurology, the People's Hospital of Longhua District, Shenzhen and recanalized successfully after endovascular treatment were enrolled. After recanalization, cold saline was infused through the guiding catheter via the ipsilateral guilty vessel (10 ℃, 33 ml/min for 30 min). Results A total of 20 patients were enrolled, including 15 males. Their median age was 67 years (interquartile range, 53-80 years). Fifteen patients were treated with thrombolysis. A median onset-to-needle time was 300 min (interquartile range, 260-360 min). During the infusion of cold saline, the lowest rectal temperature was only decreased 0. 1 ℃, but within 5 min after completion of perfusion, it returned to the temperature before perfusion. Complications associated with intra-arterial hypothermia were not observed. The median National Institutes of Health Stroke Scale score was significantly decreased from 21 (interquartile range 15-55) before needle to 15 (interquartile range 10-16; Z = -4. 549, P < 0. 001) at discharge. Conclusion Selective intra-arterial cold saline infusion combined with intravascular reperfusion for acute ischemic stroke with large artery occlusion is safe and feasible.
