ABSTRACT
Objective:To analyze the relationship between coagulation dysfunction and severity and prognosis in patients with acute severe trauma.Methods:Seventy-four patients with acute severe trauma treated at our hospital from July 2018 to September 2019 were included. According to the injury severity score (ISS) > 25 points, > 16 points and ≤25 points, and ≤16 points, patients were divided into the extremely critical group, critical group, and non-critical group. And according to the prognosis, the patients were divided into the death and survival groups. All patients had the blood coagulation function test within 24 h of admission. The coagulation function of patients in each group was compared, and the relationship between coagulation dysfunction and the severity and prognosis of patients were retrospectively analyzed.Results:There were significant differences in FIB, PT, D-D, PLT, K value, Ma value, R value and α angle among the extremely critical group, critical group, and non-critical group. FIB, PT, APTT, D-D, PLT and K value of thromboelastogram were negatively correlated with FIB and PLT in the death group and survival group, while FIB, PT, APTT, D-D, PLT and K value of thromboelastogram were positively correlated with PT and DD. Ma value was positively correlated with FIB and PLT, negatively correlated with PT and APTT, R value was positively correlated with PT, APTT, D-D and PLT, and α angle was positively correlated with FIB and PLT, and negatively correlated with PT ( P < 0.05). Conclusions:Coagulation function examination and thromboelastogram can help to determine the severity of the disease and evaluate the prognosis.
ABSTRACT
Objective:This research was designed to investigate the safety and efficiency of laparoscopic simultaneous resection in the treatment of synchronous colorectal cancer liver metastases (sCRLM).Methods:From January 2009 to December 2019, 121 patients diagnosed as sCRLM received radical resection in Peking University Third Hospital were included in the research. According to the surgery approaches, the patients were divided into laparoscopic surgery group and open surgery group. Statistical analysis of general patient data, surgical data, postoperative complications and follow-up of the two groups of patients.Results:There were 79 cases in the laparoscopic surgery group including 30 females and 49 males, and the average age was 61.5 years. There were 42 cases in the open surgery group including 15 females and 27 males, and the average age was 63.2 years. There were no significant differences in the preoperative demographic characteristics, the location of primary tumor, gene status, the size of liver metastases, the proportion of multiple liver metastases, the level of tumor markers and the proportion of neoadjuvant chemotherapy between laparoscopic surgery group and the open surgery group ( P>0.05). The complication rate was 15.2% (12/79) in the laparoscopic surgery group and 23.8% (10/42) in the open surgery group. There were no significant differences between the two groups ( P>0.05). The 3-year and 5-year survival rates in laparoscopic surgery group were 52.9% and 44.4%, which were 42.5% and 23.0% respectively in open surgery group. There were no significant differences between the two groups ( P>0.05). The 1-year and 3-year disease-free survival rate in laparoscopic surgery group were 50.6% and 41.2%, which were 44.7% and 19.4% respectively in open surgery group. There were no significant differences between the two groups ( P>0.05). Conclusions:Laparoscopic simultaneous resection was safe and feasible for patients with sCRLM. Comparing with the open surgery, the laparoscopic surgeries had similar incidence of perioperative complications and long-term oncological efficiency.
ABSTRACT
Circular RNA is a kind of single-stranded RNA ring without 5'capping and 3'polyadenylation.As a new member of non-coding RNA, circular RNA is evolutionally conserved, relatively stable,highly specific and enormously abundant.Instead of liner RNA,circular RNA became the research hotspot.So far,cerebellar degeneration-related protein 1 antisense(CDR1as)is a molecule that has garnered intense research.CDR1as harbors 74 conventional miRNA-7 binding sites.Expression of CDR1as efficiently tethers micro RNA-7, resulting in reduced micro RNA-7 activity and increased levels of micro RNA-7 targeted transcripts consistent with the micro RNA sponge and competing endogenous RNA(ceRNA)hypothesis.Moreover,CDR1as can restore micro RNA-7 and release it at right time.CDR1as can be stabilized in the exosomes.And its level has correlation with many clinical characteristics.

ABSTRACT
Colon cancer associated transcript 2 (CCAT2) is found recently an important member of cancer-related long non-coding RNA (lncRNA).Dysregulation of CCAT2 plays a pivotal role in tumor pathophysiological processes,especially in tumourigenesis and progression of digestive system neoplasms,thus,CCAT2 likely represents a novel cancer biomarker or therapeutic target.Elucidation of the molecular mechanisms of CCAT2 will provide a feasible theoretical basis and potential interventional target for the diagnosis and treatment of malignancies.The present review summarizes current evidences of CCAT2 in digestive system neoplasms.

ABSTRACT
With the advance of biology technology, non-coding RNA (ncRNA) has been confirmed to be closely associated with the occurrence and development of the cancer. The ncRNA can be divided into two groups by length, including microRNA (miRNA) and long non-coding RNA (lncRNA). As a member of lncRNA,LINC00152(long intergenic non-protein-coding RNA 152)has been taken into cancer research, which can regulate the activity of miRNA and involve the regulation of gene transcription of gene transcription and protein generation. The characteristics of LINC00152 that correlate with many clinical manifestations and can be detected in liquid biopsies make it becoming new biomarkers of cancer diagnosis. This paper reviews the current progress of LINC00152 in gastrointestinal cancer.

ABSTRACT
Tumor progression locus 2 (Tpl2) is a crucial three-stage kinase of the mitogen-activited protein kinase (MAPK) family,which plays an important role in MAPK pathway and other signaling pathways.In recent years,a large number of studies have found that aberrant expressing Tpl2 is involved in tumorigenesis and development of various cancers,and is expected to serve as a new biomarker and therapeutic target.Therefore,to reveal the mechanism of Tpl2 will provide a feasible theoretical basis and potential interventional target for the diagnosis and treatment of cancers.
ABSTRACT
It has been estimated that approximately 75% of the human genome is transcribed into RNA, 74% of which would be transcribed into non-coding RNA (ncRNA).The ncRNA can be divided into 2 major groups including small RNA and long non-coding RNA (lncRNA).There is increasing evidence that the dysregulation of lncRNA is closely associated with the occurrence and progression of many tumors.The lncRNA taurine up-regulated gene 1 (TUG1) is originally detected in a genomic screen for genes in response to taurine treatment of developing mouse retinal cells.According to research reports, dysregulation of TUG1 participates in the progression of a variety of tumors.Therefore, the regulatory effects of lncRNA TUG1 on tumorigenesis are summarized in this article.
