This dataset, collected through a comprehensive online survey and testing process, evaluates spatial visualization ability among undergraduate students at Jiaying University. Utilizing the Revised Purdue Spatial Visualization Test: Rotations (Revised PSVT: R), the dataset encompasses demographic information and responses to Likert-scale questions. With applications in experimental and cognitive psychology, the dataset offers valuable insights into spatial cognition and its implications for educational contexts.

Objectives: Over the years, it has been found that colchicine offers substantial benefits in secondary prevention in patients with coronary artery disease (CAD). We studied the effects of colchicine timing because there are no guidelines about when to provide it during the perioperative period for patients with CAD.

Methods: Up to January 1, 2023, seven electronic literature databases were screened (including three English databases and four Chinese databases).

Peripheral nerve injuries represent a great challenge for surgeons. The conductive neural scaffold has experienced increasing interest because of its good biocompatibility and similar electrical properties as compared to those of a normal nerve. Herein, nerve conduits made from poly(d,l-lactide)--poly(ethylene glycol) and polypyrrole (20%, 30%, and 50%) (PELA-PPY) were prepared by electrospinning, and used in regeneration of peripheral nerve defects.

Enteropathogenic Escherichia coli (EPEC) is a major cause of infantile diarrhea in developing countries. The translocator EspB is a key virulence factor in the process of the attaching and effacing effect of EPEC and plays a critical role in the pathogenesis of the bacteria. In this study, we aimed to select the peptides binding to EspB protein by phage display library and further investigate whether these peptides can decrease the extent of invasion and virulence of EPEC on host cells by targeting to EspB protein.

Objectives: Sucrose gel was used to treat bacterial vaginosis in a phase III clinical trial. However, the changes of vaginal flora after treatment were only examined by Nugent score in that clinical trial, While the vaginal microbiota of rhesus macaques is characterized by anaerobic, Gram-negative bacteria, few lactobacilli, and pH levels above 4.6, similar to the microbiota of patients with bacterial vaginosis.

Objective: It has been reported that LZD-resistant Enterococcus in the gastrointestinal tract of mice colonizes persistently and shows variable minimum inhibitor concentration (MIC) values. However, the colonization characteristics of Enterococcus with LZD resistance in patients remain elusive. Here, we report the case of a patient with recurrent pneumonia due to infection with LZD-resistant Enterococcus faecalis strains.

Aim: To investigate the therapeutic efficacy and mechanisms of action of oncolytic-herpes-simplex-virus encoding granulocyte-macrophage colony-stimulating factor (HSV(GM-CSF)) in pancreatic carcinoma.

Methods: Tumor blocks were homogenized in a sterile grinder in saline. The homogenate was injected into the right armpit of each mouse.

Background: Radiotherapy plays a critical role in the management of non-small cell lung cancer (NSCLC). This study was conducted to identify gene expression profiles of acquired radioresistant NSCLC cell line established by fractionated ionizing radiation (FIR) by cDNA microarray.

Methods: The human lung adenocarcinoma cell line Anip973 was treated with high energy X-ray to receive 60 Gy in 4 Gy fractions.

Objective: To study the possible role of human thrombospondin (hPWTSR) in gastric cancer and explore its potential to serve as the target for gastric cancer diagnosis and intervention.

Methods: Using pLexA-hPWTSR as the bait, a premade pB42AD-based fetal brain cDNA library was constructed to identify the interacting proteins. The expression pattern of hPWTSR in gastric cancer tissues and a gastric cancer cell line was observed to investigate the correlation between hPWTSR expression and the biological behaviors of the tumor.

Objective: To evaluate the efficacy and safty of the humanized anti-epidermal factor receptor monoclonal antibody h-R3 in combination with radiotherapy for locoregionally advanced nasopharyngeal carcinoma.

Methods: Totally, 137 patients from 7 medical center around China were randomly divided into combined therapy group or control group. There was no difference in Karnofsky performance score between two groups.

Objective: To study the radiobiological effects of fast neutron/photon mixed irradiation on human cancer cell in vitro and to discuss the mechanism in relation with cell cycle and apoptosis, thus to provide experimental support for the further application of fast neutron radiotherapy of cancer.

Methods: Exponentially growing human nasopharyngeal cancer cell line CNE-1 was irradiated in vitro with 35 MeV p-->Be fast neutron and 6 MV-X ray in grading doses (0 cGy, 40 cGy, 80 cGy, 120 cGy, 160 cGy, 240 cGy, 320 cGy and 400 cGy for neutron, and 0 cGy, 100 cGy, 200 cGy, 300 cGy, 400 cGy, 600 cGy, 800 cGy and 1000 cGy for X ray). Clonogenic assay was performed, and relative biological effectiveness (RBE) of fast neutron was determined with D(10) by means of cell survival curves.

Background & Objective: Irradiation often causes cell cycle arrest in tumor cells. This study was to observe the abrogation of radiation-induced G(2) phase arrest of p53 mutated human cancer cell lines by 7-hydroxystaurosporine (UCN-01), and explore the mechanism.

Methods: Human nasopharyngeal carcinoma cell line CNE-1 and human lung adenocarcinoma cell line 973, both with p53 mutation, were used in this study.

Objective: To evaluate the value of the "comet" assay in detecting the radiosensitivity in human tumor cell lines.

Methods: The radiation-induced primary DNA damage and repair were detected by the comet assay in CNE-1 and 973 cell lines. The tail moment was used as the end point, to quantitate the primary DNA damage and subsequent repair ability.

Background & Objective: To enhance the radiosensitivity of cancer cell is one of the most important way to improve the effect of radiotherapy. This study was designed to investigate the radiosensitization of 7-hydroxystaurosporine(UCN-01) by its abrogation of radiation-induced G2 arrest.

Methods: Flow cytometry was used to observe the effect of irradiation and UCN-01 on cell cycle of human nasopharyngeal carcinoma cells (CNE-1) with mutated p53.
