Bibliometrics and visualization analysis of esophageal cancer surgery-related researches / 中国胸心血管外科临床杂志

@#Objective     To investigate the current status of esophageal cancer surgery-related researches using bibliometric methodologies and identify the trend and hotspots. Methods     The Chinese and English literature was collected from Web of Science and CNKI from inception of each database to April 1, 2022. VOSviewer 1.6.18 and CiteSpace 6.1 were applied to cluster the authors, institutions, and keywords. For social network and time series analysis, Excel, GraphPad, and R 4.0.3 were used to visualize the literature on esophageal cancer surgery. Results     Finally, 19 566 English literature and 19 872 Chinese literature was included. The results demonstrated that the annual publishing of both Chinese and English literature increased over time, with English literature increasing rapidly and Chinese literature maintaining an average number of above 1 000 per year from 2011 to 2019. Researches were predominantly centered in Europe, the United States, Japan, South Korea, and China. China's researches in the field of surgical treatment in esophageal cancer lacked international collaboration, which began later than East Asian countries such as Japan and South Korea and had less influence. From the keyword perspective, previous researches on surgical treatment of esophageal cancer mostly focused on surgical techniques, complications, and comprehensive perioperative therapy. Both Chinese and English literature showed that the prevalence of keywords such as minimally invasive surgery, comprehensive treatment, and clinical trials increased dramatically during the recent years, indicating that these fields may represent the future directions and research trends. Conclusion     Compared to East Asia countries, such as Japan and South Korea, Chinese esophageal cancer surgery-related researches are relatively lacking. The research direction and field are similar to those in developed countries such as the United States and Europe. Future attention may be focused on minimally invasive treatment, comprehensive treatment, and clinical trials associated with surgical treatment of esophageal cancer.

Polyphyllin I promotes cell death via suppressing UPR-mediated CHOP ubiquitination and degradation in non-small cell lung cancer / 中国天然药物

Polyphyllin I (PPI) purified from Polyphyllarhizomes displays puissant cytotoxicity in many kinds of cancers. Several researches investigated its anti-cancer activity. But novel mechanisms are still worth investigation. This study aimed to explore PPI-induced endoplasmic reticulum (ER) stress as well as the underlying mechanism in non-small cell lung cancer (NSCLC). Cell viability or colony-forming was detected by MTT or crystal violet respectively. Cell cycle, apoptosis, reactive oxygen species (ROS) and mitochondrial membrane potential were assessed by flow cytometry. Gene and protein levels were evaluated by qRT-PCR and immunoblotting respectively. Protein interaction was determined by immunoprecipitation or immunofluorescence assay. Gene overexpression or silencing was carried out by transient transfection with plasmids or small interfering RNAs. The Cancer Genome Atlas (TCGA) database was used for Gene Set Enrichment Analysis (GSEA), survival analysis, gene expression statistics or pathway enrichment assay. PPI inhibited the propagation of NSCLC cells, increased non-viable apoptotic cells, arrested cell cycle at G2/M phase, induced ROS levels but failed to decrease mitochondrial membrane potential. High levels of GRP78 indicates poor prognosis in NSCLC patients. PPI selectively suppressed unfolded protein response (UPR)-induced GRP78 expression, subsequently protected CHOP from GRP78-mediated ubiquitination and degradation. We demonstrated that the natural product PPI, obtained from traditional herbal medicine, deserves for further study as a valuable candidate for lead compound in the chemotherapy of NSCLC.

Integrated targeted sphingolipidomics and transcriptomics explore the mechanism of efficacy and toxicity of Tripterygium glycosides tablets on delayed-type hypersensitivity model / 药学学报

Tripterygium glycosides tablets (TGT) have good immunosuppressive activity, but they can also significantly injure the liver and kidney and its mechanism is unclear. In this study, delayed-type hypersensitivity (DTH) Balb/c mouse were administrated with different doses of TGT. Then the changes of sphingolipids levels in live, kidney and plasma as well as the mRNA expression levels of their metabolic enzymes were studied by the integrated targeted sphingolipidomics and transcriptomics methods to reveal the mechanism of efficacy and toxicity of TGT. It was found that low dose of TGT could significantly decrease levels of total ceramide in the plasma, long chain sphingolipids and saturate sphingolipids in the liver and kidney, but increase them in the plasma, which were related to the efficacy mechanism of TGT. High dose of TGT can significantly increase levels of total ceramide, Cer(d18:1/18:0)-1-P, long chain sphingolipids and decrease saturation sphingolipids mechanism. TGT can also cause significant changes of mRNA expression levels of various sphingolipid metabolic enzymes in the liver and kidney, which were correspond to the changes of sphingolipid levels. The efficacy and toxicity of TGT were related to the regulation of these key enzyme expression levels. In conclusion, the efficacy and toxic mechanism of TGT were closely related to the sphingolipids metabolism. A variety of potential biomarkers were found and they can provide valuable information for the evaluation of the efficacy and toxicity of TGT.

Study on intra- and interatrial asynchrony in aged patients with paroxysmal atrial fibrillation / 中华老年医学杂志

Objective To evaluate intra- and interatrial asynchrony and its determinants in aged patients with paroxysmal atrial fibrillation (PAF) by using tissue Doppler imaging. Methods Ninty-one patients without PAF (control group, including 40 elder patients and 51 non-elder patients) and 52 aged patients with PAF were included. As to assessment of intra- and interatrial synchronicity, the atrioventricular plane were selected on the right atrial (RA) free wall, interatrial septum (IAS), and left atrial (LA) free wall. The time differences from the onset of the P wave to the onset of the A wave at the left atrium (P-LA), the IAS (P-IAS), and the right atrium (P-RA) were measured. Intra-atrial asynchrony was defined as the differences between P-IAS and P-RA (RA asynchrony) and between P-LA and P-IAS (LA asynchrony). Interatrial asynchrony was defined as the difference between P-LA and P-RA. Stepwise regression was made to determine the influencing factors for atrial asynchrony in aged patients with PAF. Results Compared with the control group, aged patients with PAF had significant LA and interatrial asynchrony (P＜0.01). Multivariate stepwise regression demonstrated that systolic blood pressure (x2), age (x1) and left ventricular mass index (LVMI x5) entered the regression equation in aged patients with PAF (Y=-57.241+0.481 x1+0.223 x2+0.294 x5). Conclusions Aged patients with PAF have LA and interatrial asynchrony. LVH, aged and SBP are important factors leading to these asynchronies in the aged patients with PAF.

Objective To develop a simple, fast and accurate preoperative planning method for endoscopic surgery of patients with hypertensive intracerebral hemorrhage (HICH).Methods Eighteen patients with HICH, admitted to our hospital from June 2008 to August 2010, were performed endoscopic minimally invasive surgery; CT three-dimensional reconstruction was employed to locate the intracerebral hematoma and select the appropriate endoscopic approach before the endoscopic surgery.The clinical data and treatmem efficacy were analyzed.Results According to the results of CT three-dimensional reconstruction, our neurosurgeons could design the best endoscopic approach; the three-dimensional relationship between intracerebral hematoma and scalp markers was shown directly and accurate positioning of the location of drilling was achieved; therefore, the time for preoperative preparation, anesthesia and operation was shortened. The mean operating time of these 18 patients was about 1.5 h; the volume of blood loss was only 30-40 mL; and the evacuation ratio was about 89.2%.After the elimination of hematoma, the brain tissues were flabby, so decompressive craniectomy was not needed. Conclusion CT three-dimensional reconstruction is a simple, fast and accurate preoperative planning method for endoscopic surgery of patients with HICH.
