ABSTRACT

As a highly malignant gastrointestinal tumor, pancreatic cancer is highly invasive and metastatic, which leads to the low overall survival rate of patients with pancreatic cancer. Studies have shown that long non-coding RNA (lncRNA) is involved in the development, progression, invasion, and metastasis of pancreatic cancer through epigenetic, transcriptional or post-transcriptional regulation. Dysregulated expression of lncRNA is observed in pancreatic cancer and induces epithelial mesenchymal transition (EMT) through specific regulatory mechanisms, thereby causing the changes in the biological behavior of tumor cells. This article reviews the mechanisms of lncRNA in promoting EMT, regulating tumor biological function as competing endogenous RNA, and affecting the development, invasion, and metastasis of pancreatic cancer via multiple pathways by regulating the ferroptosis, autophagy, and exosome of tumor cells, in order to provide a theoretical basis and new targets for the early diagnosis and treatment of pancreatic cancer.

ABSTRACT

Objective:To investigate the predictive value of CT perfusion imaging (CTP) parameters on the outcome after mechanical thrombosis (MT) in patients with anterior circulation acute ischemic stroke due to large vessel occlusion (LVO-AIS).Methods:The clinical data of patients with LVO-AIS received MT treatment in Taizhou People’s Hospital from July 2019 to June 2021 and achieved modified Thrombolysis in Cerebral Infarction (mTICI) blood flow grade 2b or above were retrospectively enrolled. RAPID software was used to automatically conduct image post-processing to obtain CTP parameters. The patients were divided into good outcome group (≤2) and poor outcome group (>2) according to the modified Rankin Scale score at 90 days after procedure. Multivariate logistic regression analysis was used to screen the CTP parameters that affect the outcomes. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of CTP parameters for poor outcomes. Results:A total of 88 patients with LVO-AIS were enrolled, including 52 males (59.1%), with a median age of 71 years (range 58-78 years), and the median baseline National Institutes of Health Stroke Scale (NIHSS) score of 14 (range, 11-17). Eleven patients (12.5%) received intravenous thrombolytic bridging MT, and 77 (87.5%) received direct MT. Forty-seven patients (53.4%) had good outcomes and 41 (46.6%) had poor outcomes at 90 d after procedure. Univariate analysis showed that there were significant differences in baseline NIHSS score, vascular occlusion site, baseline Alberta Stroke Program Early CT Score, the number of retrieval attempts, V CBF<30%, V Tmax>6 s, V CBF>30%/mismatch volume and hypoperfusion intensity ratio (HIR) between the poor outcome group and the good outcome group (all P<0.05). Multivariable logistic regression analysis showed that atrial fibrillation (odds ratio [ OR] 6.200, 95% confidence interval [ CI] 1.225-31.374; P=0.027), baseline NIHSS score ( OR 1.188, 95% CI 1.00-1.404; P=0.043) and V CBF<30% ( OR 1.079, 95% CI 1.03-1.123; P=0.027) were the independent influencing factors of poor outcomes. ROC curve analysis showed that the areas under the curve of atrial fibrillation, baseline NIHSS score, V CBF<30% and their combined for predicting the poor outcoms were 0.675, 0.739, 0.882 and 0.914, respectively. V CBF<30% had the highest diagnostic efficiency in predicting poor outcomes of the single factor. When the cutoff value was 16 ml, the sensitivity and specificity were 82.9% and 78% respectively. Conclusions:RAPID software analysis parameters based on CTP can be used to predict the clinical outcomes after MT in patients with LVO-AIS. V CBF<30% >16 ml has a higher predictive value for poor outcomes after MT.

ABSTRACT

Emergency medical rescue is an indispensable part of the national public health system and social security system. It is not only the direct embodiment of practicing the concept of people first and life first, but also an important manifestation to measure the emergency management level and ability of the government. The health hazards caused by public emergencies are mainly "injuries" and "diseases". With the outbreak of novel coronavirus disease-2019 (COVID-19), the construction of "disease-focused" emergency medical rescue system has made great progress in China, which in turn offers valuable experiences for the construction of high-level "trauma-focused "emergency medical rescue system. In this paper, the author reviews the development of the emergency medical rescue system in China, summarizes the experiences in fighting against COVID-19 and analyzes the development of the "trauma-focused" emergency medical rescue system, hoping to play a positive role in strengthening China′s emergency medical rescue system in the new era and better serving the grand blueprint of the rejuvenation of the Chinese nation.

ABSTRACT

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.

ABSTRACT

Objective To investigate the effect of 6-paradol on the proliferation, migration, and invasion of human intrahepatic cholangiocarcinoma cells and its mechanism. Methods Human intrahepatic cholangiocarcinoma cell lines HCCC 9810 and HUCCT1 were treated with different concentrations of 6-paradol or an equal volume of DMSO (control group), and then CCK-8 assay, plate colony formation assay, wound healing assay, and Transwell assay were used to measure cell proliferation, migration, and invasion. The bioinformatics software Swiss Target Prediction was used to predict the protein targets of 6-paradol, and Western blot was used to measure the protein expression levels of STAT3, p-STAT3, SRC, p-mTOR, p21, Bcl-2, and p53; Drug Affinity Responsive Target Stability (DARTS) assay was used to investigate the interaction between 6-paradol and STAT3. After cholangiocarcinoma HCCC 9810 and HUCCT1 cells were transfected with STAT3 overexpression plasmid or sh-p21 plasmid, quantitative real-time PCR was used to measure the mRNA expression levels of STAT3 and p21, and Western blot was used to measure the protein expression levels of STAT3 and p21; CCK-8 assay, wound healing assay, and Transwell assay were used to measure cell proliferation, migration, and invasion. The t -test was used for comparison of data between two groups; an analysis of variance was used for comparison between multiple groups, and the least significant difference t -test was used for further comparison between two groups. Results Compared with the control group, the 6-paradol treatment groups had significant reductions in cell proliferation, migration, and invasion ( P 0.05). In the 6-paradol treatment groups, the proportion of STAT3 hydrolyzed by protease was reduced by 48.66% and 45.33%, respectively ( t =16.64 and 8.76, both P < 0.05); after transfection with STAT3 overexpression plasmid or p21-silencing plasmid in cholangiocarcinoma cells, there was a significant increase in the mRNA expression level of STAT3 ( t HCCC 9810 =2.82, t HUCCT1 =5.60, both P < 0.05) and a significant reduction in the mRNA expression level of p21 ( t HCCC 9810 =6.84, t HUCCT1 =3.91, both P < 0.05). CCK-8 assay showed that for HCCC 9810 and HUCCT1 cells treated with 6-paradol for 48 and 72 hours, the STAT3 overexpression group had a significantly higher proliferation rate than the single administration group, and the p21 silencing group also had a significantly higher proliferation rate than the single administration group ( P < 0.05). The wound healing assay showed that the HCCC 9810 and HUCCT1 cells with STAT3 overexpression or p21 silencing had a significantly higher wound healing rate than the single administration group (all P < 0.05). Transwell assay showed that the HCCC 9810 and HUCCT1 cells with STAT3 overexpression or p21 silencing had significant increases in migration rate and invasion rate compared with the single administration group (all P < 0.05). Conclusion 6-Paradol inhibits the proliferation, migration, and invasion of cholangiocarcinoma cells by targeting the STAT3-p21 pathway.

ABSTRACT

Traumatic rib fractures are the most common injury in thoracic trauma. Previously,the patients with traumatic rib fractures were mostly treated non-surgically,of which 50%,especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities,being unable to retain a full-time job. In the past two decades,thanks to the development of internal fixation material technology,the surgical treatment of rib fractures has achieved good outcomes. However,there are still some problems in clinical treatment,including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans,and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore,the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association,in conjunction with national multidisciplinary experts,formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures(2021)following the principle of evidence-based medicine,scientific nature and practicality. This expert consensus puts forward some clear,applicable,and graded recommendations from aspects of preoperative imaging evaluation,surgical indications,timing of surgery,surgical methods,rib fracture sites for surgical fixation,internal fixation methods and material selections,treatment of combined injuries in rib fractures,in order to provide references for surgical treatment of traumatic rib fractures.

ABSTRACT

Circulating tumor cells are found in patients’ peripheral blood circulation, which are the key to tumor metastasis and recurrence. We can achieve early diagnosis and treatment of the tumor if we could detect circulating tumor cells through peripheral blood vessels. It is of great significance to improve the prognosis of hepatocellular carcinoma patients by studying the relationships between hepatocellular carcinoma and peripheral circulating tumor cells. Hence, this paper reviews the recent progress in the detection and clinical application of circulating tumor cells in hepatocellular carcinoma in order to provide references for clinical and related studies.

ABSTRACT

Objective:To study the dynamic changes of cellular immune function in peripheral blood of trauma patients and its role in the evaluation of traumatic complications.Methods:A prospective cohort study design was conducted. Patients with blunt trauma admitted to Chongqing Emergency Medical Center from November 2019 to January 2020 were consecutively enrolled. The peripheral blood samples were collected at 1, 3, 5, 7, and 14 days after injury. The expressions of CD64, CD274, and CD279 on the surface of neutrophils, lymphocytes, and monocytes as well as CD3 +, CD4 + and CD8 + T lymphocyte subsets were measured by flow cytometry. The trauma patients were divided into different groups according to the injury severity score (ISS) and sepsis within 28 days after injury, respectively. The dynamic changes of cellular immune function in different time points after injury and differences between different groups were compared. Furthermore, the correlation with acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), sequential organ failure assessment (SOFA), and ISS were evaluated by Pearson correlation analysis. Results:A total of 42 patients with trauma were finally enrolled, containing 8 severe trauma patients with ISS greater than 25 scores, 17 patients with ISS between 16 and 25 scores, and 17 patients with ISS less than 16 scores. The sepsis morbidity rates were 14.3% (n = 6) within 28 days after injury. CD64 index and CD4 +T lymphocyte subsets were significantly increased at different time points after trauma (H = 15.464, P = 0.004; F = 2.491, P = 0.035). The CD64 index and positive rates of CD279 in neutrophils, lymphocytes, and monocytes were increased with the severity of injury at day 1 and day 3 after injury, respectively. At the first day after injury, CD64 index were 2.81±1.79, 1.77±0.92, 3.49±1.09; positive rate of CD279 in neutrophils were 1.40% (0.32%, 2.04%), 0.95% (0.44%, 2.70%), 12.73% (3.00%, 25.20%); positive rate of CD279 in lymphocytes were 3.77% (3.04%, 5.15%), 4.71% (4.08%, 6.32%), 8.01% (4.59%, 11.59%); positive rate of CD279 in monocytes were 0.57% (0.24%, 1.09%), 0.85% (0.22%, 1.25%), 6.74% (2.61%, 18.94%) from mild to severe injury groups, respectively. The CD64 index in severe injury group was significantly higher than that in moderate group, and the positive rates of CD279 in neutrophils, lymphocytes and monocytes of severe injury patients were higher than those in other two groups (all P < 0.05). At 3rd day after injury, compared to moderate group, severe injury patients had significantly higher CD64 index and positive rate of CD279 in lymphocytes [4.58±2.41 vs. 2.43±1.68, 7.35% (5.90%, 12.28%) vs. 4.63% (3.26%, 6.06%), both P < 0.05]. Compared with the non-sepsis patients, the sepsis patients had significantly higher CD64 index and positive rate of CD279 in monocytes at day 1 after injury [4.06±1.72 vs. 2.36±1.31, 3.29% (1.14%, 12.84%) vs. 0.67% (0.25%, 1.48%), both P < 0.05], and positive rate of CD279 in lymphocytes significantly higher at 3rd day after injury [8.73% (7.52%, 15.82%) vs. 4.67% (3.82%, 6.21%), P < 0.05]. In addition, correlation analysis showed that positive rate of CD279 in lymphocytes was positively correlated with SOFA and ISS, respectively (r values were 0.533 and 0.394, both P < 0.05), positive rate of CD279 in monocytes was positively correlated with APACHEⅡ, SOFA and ISS scores, respectively (r values were 0.579, 0.452 and 0.490, all P < 0.01), positive rate of CD279 in neutrophils was positively correlated with APACHEⅡ and ISS, respectively (r values were 0.358 and 0.388, both P < 0.05). Conclusions:CD64 index and CD279 expression in neutrophils, lymphocytes, and monocytes are significantly related to the severity and prognosis of trauma. Dynamic monitoring the cellular immune function may be helpful for assessing the prognosis of trauma patients.

ABSTRACT

Hypoxia caused by rapid growth of cancer cells and insufficient central blood supply is one of the characteristics of tumor microenvironment, especially in pancreatic cancer. An increasing number of studies have shown that hypoxia is closely associated with angiogenesis, metabolic reprogramming, tumor proliferation, and early invasion and metastasis of pancreatic cancer and can mediate tumor immune evasion by secreting a variety of active factors. In addition, as a key factor for the low cure rate of pancreatic cancer, drug resistance is also associated with hypoxia. Hypoxia is closely associated with the development and progression of pancreatic cancer and depends on hypoxia-inducible factor. This article summarizes the association between hypoxic microenvironment and pancreatic cancer and discusses the activation of related signaling pathways and molecular mechanisms, in order to provide clues for targeted therapy for hopoxic microenvironment in pancreatic cancer.

ABSTRACT

OBJECTIVE: To observe the efficacy and safety of apatinib combined with systemic chemotherapy for hepatic metastasis of gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN). METHODS: Totally 60 patients with GEP-NEN in Hubei Provincial Tumor Hospital from Jan. 2016 to Jan. 2018 were randomly divided into systemic chemotherapy group, apatinib group and combination group, with 20 patients in each group. Systemic chemotherapy group was given Etoposide injection 80 mg/m2,once a day d1-5, intravenously+Cisplatin for injection 20 mg/m2,once a day d1-5,intravenously, every 3 weeks for a cycle. Apatinib group was given Apatinib mesylate tablets 0.5 g, once a day. Combination group received treatment as systemic chemotherapy group+apatinib group. All three groups were treated continuously for 3 months. The clinical efficacies of 3 groups were observed. The serum levels of tumor markers (CEA, NSE, CgA and CA19-9) before and after treatment, survival situation after treatment and the occurrence of ADR during treatment were also observed. RESULTS: The objective remission rate, disease control rate, median overall survival and survival rate of combination group were significantly higher or longer than those of systemic chemotherapy group and apatinib group. Median progression-free survival and the incidence of ADR were significantly shorter or lower than systemic chemotherapy group and apatinib group (P<0.05). After treatment, the levels of CEA, NSE, CgA and CA19-9 in 3 groups were significantly lower than before treatment, and combination group was significantly lower than systemic chemotherapy group and apatinib group (P<0.05). There was no statistical significance in above indexes between systemic chemotherapy group and apatinib group (P>0.05). CONCLUSIONS: Apatinib combined with systemic chemotherapy for liver metastasis of GEP-NEN is effective and safe, which can improve the level of serum tumor markers, prolong the survival time of patients and improve survival rate.

ABSTRACT

Objective To investigate the characteristics of pulmonary function and pathological changes in rats with acute lung injury (ALI) and provide experimental basis for further study on the mechanism of ALI.Methods Twenty five male SD rats were randomly divided into the control group (n =5) and acute lung injury (ALI) group (n =20).Lipopolysaccharide (LPS) (4.5 mg/kg) were injected into the ALI group rats to establish the ALI rat model.The rats in control group were given 150 μl isotonic saline.At 12,24,48,and 72 hours after injury,lung function of the rats were tested by Buxco small animal lung function test system,including the dynamic lung compliance (Cdyn),forced vital capacity (FVC),functional residual gas (FRC),quasi static compliance (Cchord),100th millisecond expiratory volume (FEV100),and airway resistance (RI).In addition,the bronchoalveolar lavage fluid (BALF) was collected for detection of protein level and tumor necrosis factor (TNF-alpha)concentration.At the same time,the changes of lung tissues were recorded,and the pathological changes were observed by HE staining.Results Compared with the control group,Cdyn,FVC,FRC,and FEV100 in ALI group were significantly decreased at each time point after injury (P <0.05 or <0.01),while the airway resistance (R1) in ALI group was significantly increased at 24 and 48 hours after injury (P < 0.01).There was no significant difference in quasi static compliance (Cchord) between two groups (P > 0.05).The protein level and TNF-alpha concentration of BALF in ALI group were increased significantly (P <0.05 or <0.01) 12-72 hours after injury (P < 0.01).Compared with the control group,the whole lung was dark red in ALI group 12 hours after injury,and the most serious bleeding occurred in the pulmonary hilum area with single or multiple hemorrhagic foci of different sizes.Multiple punctate and focal bleeding of different sizes were seen on the lung surface,which were radially distributed around the pulmonary hilum.The color of lung tissue was gradually restored to normal at 72 hours after injury.Under the light microscope,pulmonary interstitial edema,inflammatory cell infiltration,pulmonary vascular congestion and focal pulmonary hemorrhage were observed 12 h after injury,showing typical ALl pathological changes.The pathological changes were the most significant at 24 hours and reduced obviously at 72 hours.Conclusions A single intratracheal injection of LPS can induce typical ALI pathological changes.There is a similar trend between the pulmonary function indexes,lung pathology characteristics,and the protein level of BALF and proinflammatory cytokine level,suggesting that the pulmonary function test parameters can provide reference for evaluation of ALI.

ABSTRACT

Objective To determine the effect of fatigue on the risk of anterior cruciate ligament (ACL) injuries using a controlled experiment.Method Thirty-two young male adults were selected.Half of them were asked to complete landing and sudden cutting tasks when feeling fatigue,while the rest were asked to conduct the same tasks without fatigue.Results The results indicated that fatigue led to increased knee flexion and knee rotation of the support leg during the initial landing,It also resulted in significant increase in the peak knee flexion,knee internal rotation angle and knee internal rotation moment during the double support phase.Moreover,the peak value of the knee flexion angle and knee internal rotation angle increased significantly due to fatigue during the single leg support period.Conclusion Being fatigue,people might take the adaptive posture control to decrease the ground shock,which in turn decreases ACL injury risks.However,it can be neutralized by the increase in the rotational angle.

ABSTRACT

Objective To investigate the clinical efficacy of re-modified Sugiura procedure for the treatment of portal hypertension.Methods The retrospective cohort study was adopted.The clinical data of 119 patients with portal hypertension who were admitted to Second People's Hospital of Yichang from June 2006 to October 2014 were collected.Seventy-two patients who underwent pericardial devascularization were allocated into the Hassab group,and the other 47 patients who underwent the re-modified Sugiura procedure were allocated into the R-M Sugiura group.All the patients firstly underwent splenectomy.The patients of the Hassab group received the classical surgery of pericardial devascularization,and the operation in the R-M Sugiura group was improved on the modified Sugiura procedure in several aspects:(1) the cardia was transected obliquely.(2) Paraesophageal vessels were preserved by selective pericardial devascularization.(3) The pedicled omentum covered the anterior anastomosis and was sutured to the posterior abdominal wall.Observed indices included (1) intraoperative and postoperative situations:operation time,volume of intraoperative blood loss,postoperative anal exhaust time and duration of postoperative hospital stay.(2) Postoperative complications:postoperative pleural effusion,perioperative digestive tract re-bleeding,difficult swallowing,portal vein thrombosis and gastric dynamic dysfunction.(3) Situation of follow-up.The follow-up was performed by telephone interview and outpatient examination to observe the grading of the esophageal varices at postoperative month 6 and 18 using gastroscope till February 2016.Measurement data with normal distribution were presented as x ± s,and comparison between groups was done by the t test.Count data were analyzed by the chi-square test.Ranked data were analyzed by Wilcoxon rank test.Results (1) Intraoperative and postoperative situations:operation time of the Hassab group and the R-M Sugiura group was (201 ± 27) minutes and (255 ± 32) minutes,respectively,with a statistically significant difference between the 2 groups (t =9.67,P < 0.05).The volume of intraoperative blood loss,postoperative anal exhaust time and duration of postoperative hospital stay were (380 ± 86) mL,(2.7 ± 0.7) days,(14.2 ± 2.4) days in the Hassab group and (401 ± 72) mL,(3.0 ± 1.7) days,(15.1 ± 2.7) days in the R-M Sugiura group,respectively,showing no statistically significant difference (t =1.35,1.26,1.86,P > 0.05).(2) Postoperative complications:dysphagia was detected in 3 patients of the Hassab group and in 10 patients of the R-M Sugiura group at the postoperative day 10,with a statistically significant difference between the 2 groups (x2 =0.86,P < 0.05).However,dysphagia was detected in 1 patient of the Hassab group and in 4 patients of the R-M Sugiura group at the postoperative day 20,showing no statistically significant difference between the 2 groups (x2 =2.03,P > 0.05).The number of postoperative pleural effusion,perioperative digestive tract rebleeding,portal vein thrombosis and gastric dynamic dysfunction of the Hassab group and the R-M Sugiura group were 23,6,10,8 cases and 20,1,6,6 cases,respectively,showing no statistically significant difference (x2=1.39,1.02,0.03,0.08,P > 0.05).(3) Situation of follow-up:all the patients were reexamined using gastroscope to observe the grading of esophageal varices.There were 0,7,56,9 patients of G0,G Ⅰ,G Ⅱ,G Ⅲ grading of varices in the Hassab group and 35,12,0,0 patients in the R-M Sugiura group at postoperative month 6,showing a statistically significant difference between the 2 groups (Z =-9.64,P < 0.05).There were 0,0,48,24 patients of G0,G Ⅰ,G Ⅱ,G Ⅲ grading of varices in the Hassab group and 24,20,3,0 patients in the R-M Sugiura group at postoperative month 18,showing a statistically significant difference between the 2 groups (Z =-9.28,P < 0.05).Conclusion The re-modified Sugiura procedure is more effective than the Hassab operation in curing portal hypertension,and it could also reduce the rate of rehemorrhage and improve the short-term and long-term prognosis.

ABSTRACT

Objective To set up a warning diagnostic model by using the commonly used clinical indicators in an attempt to provide a basis for the early,fast and accurate diagnosis of posttraumatic sepsis.Methods Based on the presence of sepsis,165 patients were grouped into sepsis group (n =45) and non-sepsis group (n =120).Body temperature,respiration,heart rate,C-reactive protein(CRP),white blood cell,blood platelet count(PLT),activated partial thromboplastin time (APTT),acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and sepsis-related organ failure assessment(SOFA) score were tested to identify the independent predictors of sepsis.Warning diagnostic models of unweighted score (unwScore) and weighted score (wScore) for posttraumatic sepsis were constructed by combining the independent variables.Receiver operation characteristic curve (ROC) was used to evaluate the independent predictor and warning diagnostic models for posttraumatic sepsis.Results Body temperature,respiration,heart rate,CRP,APACHE Ⅱ score and SOFA score were significantly different between the two groups(P < 0.05).Multiple analysis showed body temperature,CRP and APACHE Ⅱ score were independently associated with sepsis.With the ROC analysis,areal under the curve (AUC),sensitivity,specificity,positive predictive value and negative predictive value of unwScore (0.915,0.87,0.85,69.64% and 94.50%) and wScore (0.931,0.96,0.78,63.24% and 97.85%) were better than these of body temperature (0.855,0.84,0.78,59.38% and 93.07%),CRP (0.761,0.64,0.80,55.77% and 85.84%) and APACHE Ⅱ (0.884,0.84,0.82,64.41% and 93.40%).Conclusions Body temperature,CRP and APACHE Ⅱ score are independent predictors of sepsis.Models combining body temperature,CRP and APACHE Ⅱ score demonstrate high performance in diagnosing sepsis in trauma patients.

ABSTRACT

Objective To investigate the effects of miR-100 on the proliferation of MIA PaCa-2 and CFPAC-1 cells through targeting fibroblast growth factor receptor 3 (FGFR3).Methods miR-100 expression levels in 17 cancer tissues and 17 nonmalignant tissues were examined by Real-time PCR.The effect of miR-100 overexpression on cell proliferation was examined by CCK-8 assay in vitro.Luciferase assay was used to confirm that miR-100 could directly target FGFR3.Real-time PCR and Western blot were used to examine the expression of FGFR3 in miR-100 overexpressing pancreatic cancer cells.The predicted target gene of miR-100,FGFR3,was downregulated by siRNA,and its effect on cell proliferation was also examined.Cell proliferation was analyzed using CCK-8 and Edu assay.Results miR-100 was lowly expressed in pancreatic cancer tissues (P < 0.05).In pancreatic cancer cells,the transfection of lv-miR-100 was able to upregulate the endogenous expression of miR-100 and inhibit the cell proliferation (P <0.05).Luciferase assay showed FGFR3 was the direct target of miR-1O0.FGFR3 was significantly downregulated by overexpressing miR-100 in pancreatic cancer cells (P <0.05),and FGFR3 knockdown by specific siRNA exerted the similar effect as miR-100 overexpression (P < 0.05).Conclusions Our study identified a new miRNA regulator,miR-100,and clarified a novel mechanism of how miR-100 regulates cell proliferation in pancreatic cancer.The strategy of overexpressing the tumor suppressor miR-100 may provide a new therapeutic approach for treating patients with pancreatic cancer.
