Immune-related long noncoding RNA zinc finger protein 710-AS1-201 promotes the metastasis and invasion of gastric cancer cells

BACKGROUND Gastric cancer(GC)is a prevalent malignant tumor of the gastrointestinal system.ZNF710 is a transcription factor(TF),and zinc finger protein 710(ZNF710)-AS1-201 is an immune-related long noncoding RNA(lncRNA)that is upregulated in GC cells.AIM To assess the correlation between ZNF710-AS1-201 and immune microenvir-onment features and to investigate the roles of ZNF710-AS1-201 in the invasion and metastasis processes of GC cells.METHODS We obtained data from The Cancer Genome Atlas and Wujin Hospital.We assessed cell growth,migration,invasion,and programmed cell death using cell counting kit-8,EdU,scratch,Transwell,and flow cytometry assays.Quantitative real-time polymerase chain reaction(qRT-PCR)was used to identify the potential downstream targets of ZNF710-AS1-201.RESULTS In GC tissues with low ZNF710-AS1-201 expression,immunoassays detected significant infiltration of various antitumor immune cells,such as memory CD8 T cells and activated CD4 T cells.In the low-expression group,the half-maximal inhibitory concentrations(IC_(50)s)of 5-fluorouracil,cisplatin,gemcitabine,and trametinib were lower,whereas the IC_(50)s of dasatinib and vorinostat were higher.The malignant degree of GC was higher and the stage was later in the high-expression group.Additionally,patients with high expression of ZNF710-AS1-201 had lower overall survival and disease-free survival rates.In vitro,the overexpression of ZNF710-AS1-201 greatly enhanced growth,metastasis,and infiltration while suppressing cell death in HGC-27 cells.In contrast,the reduced expression of ZNF710-AS1-201 greatly hindered cell growth,enhanced apoptosis,and suppressed the metastasis and invasion of MKN-45 cells.The expression changes in ZNF710 were significant,but the corresponding changes in isocitrate dehydrogenase-2,Semaphorin 4B,ARHGAP10,RGMB,hsa-miR-93-5p,and ZNF710-AS1-202 were not consistent or statistically significant after overexpression or knockdown of ZNF710-AS1-201,as determined by qRT-PCR.CONCLUSION Immune-related lncRNA ZNF710-AS1-201 facilitates the metastasis and invasion of GC cells.It appears that ZNF710-AS1-201 and ZNF710 have potential as effective targets for therapeutic intervention in GC.Nevertheless,it is still necessary to determine the specific targets of the ZNF710 TF.

Exploring the characteristics of inquiry and the correlation with TCM syndromes about the patients with cardiovascular disease

Objective:Inquiry occupies an important position in the Traditional Chinese Medicine(TCM)diagnostic methods.Observing the characteristics of inquiry symptoms and the correlation with TCM syndromes can determine the important guiding significance to build recognition model and diagnostic criteria of syndrome.Methods:In this study,we collected 3707 valid cases,analyzed the inquiry symptoms of patients with cardiovascular disease,then to explore the distribution of inquiry information and the correlation with TCM syndromes based on the methods,such as frequency analysis,expert score,and correlation analysis.Results:We found the symptoms of frequency analysis and expert symptom score all in the top 50,add up to 41.According to the results by correlation analysis,the correlation coefficient between each symptom and each syndrome are sorted from high to low,the same with the experts score to each inquiry symptom basing on its importance of in diagnosing each syndrome.Conclusion:Inquiry occupies an important effect in differentiation syndrome.This research could provide certain objective basis for establishment of TCM syndromes diagnostic criteria of cardiovascular disease,thus provide some ideas and methods for the research of establishing TCM syndrome identification model,then to provide a reference for the syndrome standardization and objectification.

Use of Non-Verbal Representations to Define Concept of Pulse Conditions in Traditional Chinese Medicine Standards

The standardization of terms and definitions is fundamental to all activities in the domain of traditional Chinese medicine(TCM).For decades,definitions of TCM terminology relied on conventional verbal representations to differentiate between related concepts.However,the ancient Chinese is obscure and comprises a massive volume of information,making it difficult to convey the definition accurately in other languages.This article proposes a potential solution that the definition for pulse terminology can be supplemented by modern means of non-verbal representation,i.e.,using pulse waveform graphs and parameters to complete the definition of each pulse.A discussion of the challenges of obtaining reliable data is also included.

Preliminary study on phonetic characteristics of patients with pulmonary nodules

Objective: Pulmonary nodules(PNs) are one of the imaging manifestations of early lung cancer screening,which should receive more attention. Traditional Chinese medicine believes that voice changes occur in patients with pulmonary diseases. The purpose of this study is to explore the differences in phonetic characteristics between patients with PNs and able-bodied persons.Methods: This study explores the phonetic characteristics of patients with PNs in order to provide a simpler and cheaper method for PN screening. It is a case-control study to explore the differences in phonetic characteristics between individuals with and without PNs. This study performed non-parametric statistics on acoustic parameters of vocalizations, collected from January 2017 to March 2018 in Shanghai,China, from these two groups;it explores the differences in third and fourth acoustic parameters between patients with PNs and a normal control group. At the same time, computed tomography(CT) scans,course of disease, combined disease and other risk factors of the patients were collected in the form of questionnaire. According to the grouping of risk factors, the phonetic characteristics of the patients with PNs were analyzed.Results: This study was comprised of 200 patients with PNs, as confirmed by CT, and 86 healthy people that served as a control group. Among patients with PNs, 43% had ground glass opacity, 32% had nodules with a diameter ≥ 8 mm, 19% had a history of smoking and 31% had hyperlipidemia. Compared with the normal group, there were statistically significant differences in pitch, intensity and shimmer in patients with PNs. Among patients with PNs, patients with diameters ≥ 8 mm had a significantly higher third formant. There was a significant difference in intensity, fourth formant and harmonics-to-noise ratio(HNR)between smoking and non-smoking patients. Compared with non-hyperlipidemia patients, the pitch, jitter and shimmer of patients with PNs and hyperlipidemia were higher and the HNR was lower;these differences were statistically significant.Conclusion: This measurable changes in vocalizations can be in patients with PNs. Patients with PNs had lower and weaker voices. The size of PNs had an effect on the phonetic formant. Smoking may contribute to damage to the voice and formant changes. Voice damage is more pronounced in individuals who have PNs accompanied by hyperlipidemia.

Use of contrast-enhanced ultrasound during preoperative evaluation of endometrial carcinoma

Objective:To explore the clinical role of contrast-enhanced ultrasound(CEUS)in a preoperative evaluation of early endometrial carcinoma.Methods:This study included 14 patients who underwent preoperative CEUS and contrast-enhanced magnetic resonance imaging(CEMRI)and were ultimately diagnosed with stage I endometrial carcinoma from December 2019 to December 2020.The parameters of the time-intensity curve(TIC)were compared with the endometrial carcinoma group,the invaded myometrium group,and the normal myometrium group.Results:TIC parameters between the endometrial carcinoma group and the invaded myometrium group were similar.Compared with the normal myometrium group,the time to peak(TTP)was significantly shorter and the ascending slope(AS)was significantly higher in the endometrial carcinoma group.The TTP of the invaded myometrium group was shorter than that of the normal myometrium group and the peak intensity(PI)was higher than that of the normal myometrium group.We then compared the TIC parameters between the endometrial carcinoma group and the invaded myometrium group after adjusting for the normal myometrium group,and the results still did not show any difference.Of the 14 cases of endometrial carcinoma,9 cases were diagnosed by CEMRI and were consistent with the pathology results,1 case was underestimated,and 4 cases were overestimated;while 11 cases diagnosed were diagnosed by CEUS and were consistent with the pathology results,1 case was underestimated,and 2 cases were overestimated.Conclusions:The contrast pulse sequencing technique used in the CEUS examinations performed well in evaluating the extent of the endometrial carcinoma.Future studies with larger sample sizes are needed to determine the applicability and value of this new procedure during preoperative assessments of early endometrial carcinoma.

Characteristics of Traditional Chinese Medicine Syndrome in Patients with Coronary Heart Disease at Different Disease Stages

Coronary atherosclerotic heart disease(CHD)has a high incidence,disability rate,and mortality rate,which severely affect people’s health,work,and life.Based on its clinical manifestations,traditional Chinese medicine(TCM)has classified CHD as“chest impediment”and“heart pain”for the treatment.The course of CHD is protracted,and the pathogenesis is complex and changeable.Moreover,different disease stages have different syndrome characteristics.Thus,this article aimed to summarize the classification and distribution characteristics of the TCM syndrome in various stages of CHD,such as before and after percutaneous coronary intervention therapy,disease progression,age,and complications,to provide references for the TCM clinical diagnosis and treatment of CHD.
