Objective To investigate the expressions of a disintegrin and metalloprotease 17 (ADAM17) and epidermal growth factor recepter (EGFR) in human esophageal squamous cell carcinoma (ESC),and to explore their relationship with clinicopathological characteristics.Methods The paraffin specimens in postoperative pathological tissues of 66 ESC patients in the Third People's Hospital of Hefei from January 2013 to December 2017 were selected.Expressions of ADAM17 and EGFR proteins were examined by using immunohistochemistry in 66 cases of ESC tissues and 33 cases of adjacent tissues of the tumors.The relationship of ADAM17 and EGFR with clinicopathological features was analyzed.Kendall method was used to detect the expression correlation of ADAM17 and EGFR.Results The positive rate of ADAM17 protein in ESC tissues was higher than that in the adjacent tissues of the tumors [68.2 ％ (45/66) vs.33.3 ％ (11/33),x2 =10.874,P =0.001].The positive rate of EGFR protein in ESC tissues was higher than that in the adjacent tissues of the tumors [66.7 ％ (44/66) vs.39.4 ％ (13/33),x2 =6.699,P =0.01].The expressions of ADAM17 and EGFR protein were related with ESC pathological TNM staging,infiltration depth,lymph node metastasis (x2 =4.797,4.890,6.089;8.790,8.766,10.154,respectively,all P ＜ 0.05).ADAM17 expression was positively correlated with EGFR protein (r,=0.368,P ＜ 0.05).Conclusions ADAM17 and EGFR are highly expressed in human ESC.Besides,ADAM17 and EGFR have the interaction in the occurrence and development of esophageal cancer.Joint detection may help to determine the degree of metastasis and evaluate prognosis.

Most patients with spinal cord injury suffer from limb motor dysfunction. Given drugs, surgery and other conventional treatments are often not effective, the patients can only rely on a wheelchair to move or even lie in bed for a long time, seriously affecting their quality of life. Brain computer interface (BCI) technology provides a non-muscular pathway for the recovery of motor function in patients with spinal cord injury, which allows the patients to recover partial motor function through the normal function of their own non-diseased spinal cord or external mechanical devices. After decades of development of BCI technology, signal collection devices can identify and collect the motor signals of the brain more accurately, transform the signal by characteristic analysis, and implement the brain command by using the output device. A large number of experimental and clinical studies have also proved that the application of BCI technology in patients with spinal cord injury can partially improve the motor function of upper and lower limbs. Therefore, BCI technology has attracted more and more attention. The authors summarized the BCI technology and its influence on motor function rehabilitation in patients with spinal cord injury, so as to provide a reference for the rehabilitation of motor function in patients with spinal cord injury.

ObjectiveTo explore the current status, hot spots and development of researches on post-stroke dysphagia in recent five years with visualization analysis. MethodsResearches on post-stroke dysphagia were retrieved from Web of Science Core Collection, from January 1st, 2017 to December 31st, 2021, and reviewed with CiteSpace 5.7.R5 software. ResultsA total of 857 articles were included. The annual number of articles increased with time, published from 61 countries/regions, by 211 institutions and 247 authors. The United States, Japan and China were the most prolific countries, and the University of Manchester was the leading institution. The top three authors were Dziewas R, Wakabayashi H and Hamdy S. The keywords bursting in recent three years included prediction, severity, percutaneous endoscopic gastrostomy, accuracy and early management; co-word clustering showed that researches might be mainly about neuromuscular electrical stimulation, swallowing screening, stroke-associated pneumonia, evidence-based practice, etc. ConclusionThe researches in the field of post-stroke dysphagia have been increasing.

OBJECTIVETo investigate the features of oral lesions in patients with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS).

METHODSA total of 127 HIV-seropositive patients were interviewed for health information and examined for their HIV-related oral lesions according to the EC Clearing House Criteria on Oral Problems related to HIV-Infection (1992). The examinations were conducted by dental specialist and HIV specialist. The CD4 T cell count in peripheral blood of the patients was tested by flow cytometry. The patients were divided into HIV- infected group (42) and AIDS group (85) according to CDC Classification System for HIV- Infected Adults and Adolescents (revised in 1993). Chi-square test was used to test the relationship between systemic disease and oral lesions, and the difference of the prevalence of oral lesions between the two groups.

RESULTSAmong the 127 patients, oral candidiasis (51/127), oral hairy leukoplakia (24/127) were common oral manifestation. There was no relationship between the oral manifestation and systemic disease (P = 0.397). The occurrence of oral lesions and oral candidiasis was significantly different between the two groups (χ² = 7.684, P = 0.006; χ² = 14.410, P < 0.001). The CD4 count was related to the prevalence of oral lesions (P = 0.006) and oral candidasis (P = 0.003).

CONCLUSIONSMost oral lesions appeared before the appearance of systemic disease. Oral candidiasis and oral hairy leukoplakia were the most common lesions.Oral lesions had no relationship with systemic disease but could be still an indicator for disease progress.
