Objective To investigate the association between expression of the epithelial?to?mesenchymal transition(EMT)biomarkers and the malignant progression of gastric cancer in primary tumors and metastases and their possible correlation with progression of gastric cancer(GC). Methods The EMT biomarkers including E?cadherin,β?catenin,N?cadherin,Snail and TGF?β1 were detected by immunohistochemical method for 145 cases of gastric cancer(GC),25 cases of abnormal hyperplasia,13 cases of intestinal metaplasia,42 cases of lymph node metastasis and 40 cases of normal gastric mucosa tissues. Results Positive rates of TGF?β1,Snail,E?cadherin,β?catenin and N?cadherin were 73.5%,65.5%, 14.5%,53.1%and 35.9%,respectively,in gastric cancer tissues and 100%,100%,0%,27.5%and 2.5%,respectively,in normal gastric tissues, with a significant difference between the two groups(P<0.05). The decreased expression of E?cadherin andβ?catenin and the increased expression of TGF?β1 were related to the depth of invasion of gastric cancer(P<0.05). The expression of E?cadherin was correlated positively with the expres?sion ofβ?catenin,but negatively with the expression of TGF?β1. Whereas,the expression of N?cadherin was correlated positively with the expression of TGF?β1(P<0.05). The expression of E?cadherin andβ?catenin in lymph node metastasis was significantly higher than that in gastric cancer tis?sues,while the expression of TGF?β1 was lower than in gastric cancer tissues(P<0.05). Conclusion The increased expression of TGF?β1 and Snail and the decreased expression of E?cadherin,β?catenin,and N?cadherin are involved in the processes of invasion and metastasis of GC. The transformation of E?cadherin to N?cadherin and the expression of TGF?β1 may play an important role in the development of GC. In lymph node me?tastasis,the phenomenon of mesenchymal?to?epithelial transition(MET)occurs.

Objective To evaluate the efficacy of adductor canal block combined with infiltration anesthesia for postoperative analgesia in the patients undergoing total knee arthroplasty. Methods Sixty pa?tients of both sexes, aged 65-80 yr, weighing 40-80 kg, of American Society of Anesthesiologists physi?cal statusⅠ or Ⅱ, scheduled for elective unilateral total knee arthroplasty, were divided into 3 groups ( n=20 each) using a random number table: single?injection adductor canal block + infiltration anesthesia group ( group A) , single?injection femoral nerve block+infiltration anesthesia group ( group F) , and infil?tration anesthesia group ( group I) . Ultrasound?guided adductor canal block and femoral nerve block were performed with 0.5% ropivacaine 20 ml before induction of anesthesia in A and F groups, respectively. Af?ter completion of the block, all the patients were ventilated through the laryngeal mask airway under general anesthesia. After installation of the knee prosthesis, local infiltration anesthesia was conducted with 0.2%ropivacaine 50 ml around the knee joint. Acetaminophen oxycodone capsule was taken orally one pill every 6 h starting from the morning on 1st day after surgery. When visual analogue scale ( VAS) score > 5, tram?adol 100 mg was injected intramuscularly as rescue analgesic. At 4, 8, 24, 48 and 72 h after surgery, VAS scores at rest and during activity were recorded, the quadriceps strength was measured, and the re?quirement for analgesic drugs and development of adverse reactions were recorded. Results Compared with
group I, VAS scores at rest and during activity were significantly decreased at 4, 8, and 24 h after surger?y, and the consumption of tramadol was significantly decreased after surgery in A and F groups ( P<0.05) . The quadriceps strength at 4 and 8 h after surgery was significantly higher in A and I groups than in group F ( P<0.05) . No patients developed serious adverse reactions in the three groups. Conclusion Adductor ca?nal block combined with infiltration anesthesia provides reliable efficacy for postoperative analgesia with little influence on the quadriceps strength in the patients undergoing total knee arthroplasty.

Objective To evaluate the applications of magnetic resonance cholangiopancreatography (MRCP) after fat meal in the preoperative evaluation of biliary anatomy of living liver donors.Methods Fifty cases of the preoperative donors for living liver transplantation were included and all had the corresponding intraoperative cholangiography (IOC) information. The MRCP of the donors for living liver transplantation was performed before and after fat meal (two fried eggs). The visualization and diameter of the secondary bile duct were analyzed before and after the fat meal. The results of the biliary branching pattern by MRCP after fat meal were compared with the corresponding IOC results. The accuracy, sensitivity,specificity, positive predictive value and negative predictive value of MRCP after the fat meal in distinguishing normal and any type of variant biliary anatomy were calculated. Results In all cases,82% of the 50 cases in MRCP before the fat meal could meet the diagnosis needs of the preoperative evaluation,and 100% of the 50 cases in MRCP after the fat meal could meet the diagnosis needs. There was significant difference in the demonstration quality and diameter of the secondary bile duct in MRCP before and after the fat meal (P＜0. 05). MRCP showed accurate anatomy of the biliary system, using IOC as the reference standard, in 49(98%) subjects. The sensitivity, specificity, positive predictive value and negative predictive value of MRC in distinguishing normal and any type of variant biliary anatomy were 98%,94. 7%, 100%, 10% and 96. 9%,respectively. Conclusion The MRCP after fat meal can clearly demonstrate the secondary bile duct and perfectly meet the needs of the preoperative evaluation of the living liver transplantation. The MRCP after fat meal and routine MRCP should be considered complementary to one another in order to avoid complications in living liver transplantation donors.

Purpose: The influence of fasting blood glucose (FBG) and cholesterolemia primary liver cancer (PLC) in china was analyzed via a large prospective cohort study based on a community population, and the combined effects between them were investigated. Materials and Methods: Overall, 98,936 staff from the Kailuan Group who participated in and finished physical examinations between 2006 and 2007 were included in the cohort study. Their medical information was collected and they were followed up after examination. The correlations of serum FBG or TC with PLC were analyzed. Then, we categorized all staff into four groups: normal FBG/ non-hypocholesterolemia, normal FBG/hypocholesterolemia, elevated FBGon-hypocholesterolemia, elevated FBG/hypocholesterolemia and normal FBG/ non-hypocholesterolemia was used as a control group. The combined effects of elevated FBG and hypocholesterolemia with PLC were analyzed using the Age-scale Cox proportional hazard regression model. Results: During 1,134,843.68 person*years follow up, a total of 388 PLC cases occured. We found the elevated FBG and hypocholesterolemia increases the risk for PLC, respectively. Compared with the non-hypocholesterolemiaormal FBG group, the risk of PLC was significantly increased in the non-hypocholesterolemia/elevated FBG group (HR=1.19,95%CI 0.88–1.62) and hypocholesterolemiaormal FBG group (HR=1.53,95%CI 1.19–1.97), and in the hypocholesterolemia/elevated FBG group (HR=3.16 95%CI2.13-4.69). And, a significant interaction effect was found of FBG and TC on PLC. All results were independent from the influence of liver disease. Conclusion Elevated serum FBG and hypocholesterolemia are risk factors for PLC, especially when combined. Thus, for the prevention and treatment of PLC, serum FBG and TC levels should be investigated.

Objective To investigate the anatomical structure of the first plantar lumbrical muscle in the foot and to measure the relevant data which could provide anatomical basis for repairing thumb and finger defects with the transplantation of toes accompanied with the first lumbrical muscle,and to explore the marphological function of the first lumbrical muscle of the foot.Methods From March,2016 to January,2018,a systematic and detailed dissection of the 50 formalin-fixed feet was performed to observe the exact position of the starting and ending points of the first lumbrical muscle,and a Vernier caloper was used to measure the relevant record data.Results The first lumbrical muscle originates from the medial portion of the flexor digitorum lungus tendon of the second toe,and the length of the ventral muscle was [55.87±8.67(79.30-41.16] mm.There were 2 endpoints in the tendon.The first one was in the medial tubercle of the proximal phalanges.The second one was aponeurosis of the dorsal toe and the tendon was divided into proximal and distal segments with the medial tubercle as the mark point.The length of the proximal segment was [15.34±4.81(5.52-25.18] mm,the width of the proximal segment was [2.31±1.12(3.28-1.21)] mm,the thickness was [0.44±0.14(0.28-0.68)] mm;the length of the distal segment was [11.51±4.06(3.46-14.90)] mm,the width was [6.10±1.44(9.36-3.70)] mm,and the thickness was [0.18±0.09(1.10-0.38)] mm.The length and thickness of the proximal segment was signifantly larger than those of the distal segment (P＜0.05).Conclusion The first lumbrical muscle has the function of maintaining the balance and stability of both the toe and the arch during movement,flexuring the metatarsophalangeal joint,extending the interosseous joint of the extensor phalangeal,adducting the second toe;also the function of preventing the second toe from pronation during foots' movement.

The root bark extract of Aralia taibaiensis is used traditionally for the treatment of diabetes mellitus in China. The total saponin extracted from Aralia Taibaiensis (sAT) has effective combined antihyperglycemic and hypolipidemic activities in experimental type 2 diabetic rats. However, the active compounds have not yet been fully investigated. In the present study, we examined effects of twelve triterpenoid saponins on AMP-activated protein kinase (AMPK) activation, and found that compound 28-O-β-D-glucopyranosyl ester (AT12) significantly increased phosphorylation of AMPK and Acetyl-CoA carboxylase (ACC). AT12 effectively decreased blood glucose, triglyceride (TG), free fatty acid (FFA) and low density lipoprotein-cholesterol (LDL-C) levels in the rat model of type 2 diabetes mellitus (T2DM). The mechanism by which AT12 activated AMPK was subsequently investigated. Intracellular ATP level and oxygen consumption were significantly reduced by AT12 treatment. The findings suggested AT12 was a novel AMPK activator, and could be useful for the treatment of metabolic diseases.

Objective To provide a reliable and stable animal model for investigating the molecular pathogenesis of radiation-induced liver disease (RILD). Methods Ninety C57BL/6J mice were divided into control, 20 Gy, 25 Gy, 30 Gy and 35 Gy radiation groups. The mice were executed at 4 weeks after radiation and the levels of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase in the liver serum were measured. HE staining was performed on the pathological liver tissues. Masson staining was performed at 36 weeks after radiation. Results Compared with the control group, the fatality rate was higher in the 30 and 35 Gy radiation groups, and the body weight significantly decreased in the 20 and 25 Gy radiation groups. Compared with the control group, alanine aminotransferase significantly increased in mice exposed to 20 Gy, while aspartate aminotransferase and alanine aminotransferase increased in mice exposed to 25 Gy. No significant changes were observed in the livers of the mice in the 20 and 25 Gy radiation groups, but pathological examination showed liver damage induced by both 20 and 25 Gy radiation. Conclusion A stable and reliable mouse model of RILD was constructed for treatment with linear accelerator. The mouse model of RILD constructed for stereotactic body radiation therapy using linear accelerator has significant research implications for the exploration of RILD.

Objective: To explore the effect of comprehensive rehabilitation treatment of individualized exercise program on lung function, exercise ability, quality of life and biochemical indexes of coal workers’ pneumoconiosis patients, and to provide scientific and effective methods for rehabilitation treatment of coal workers' pneumoconiosis. Methods: In Huaibei Coal Mine Occupational Disease Prevention and Control Hospital, the data of pneumoconiosis patients treated by pneumoconiosis department in the hospital were collected and sorted out. 80 patients were selected according to the inclusion and exclusion criteria. Using a random number table, they were randomly divided into two groups with 40 cases in each group. The data investigated in this study include the results before and after treatment. Pulmonary function index, BMI index, six-minute walking distance (6MWD) , quality of life questionnaire (SF-36) , hospital anxiety and depression scale (HADS) , st George's breathing questionnaire (sgrq) , c-reactive protein (CRP) and blood oxygen saturation (SpO₂) were used to evaluate and compare the efficacy of the two groups. Results: The lung function indexes of the test group were significantly higher than those of the control group after treatment (P<0.05) , including forced vital capacity, forced vital capacity in the first second, maximum expiratory flow, expiratory flow when vital capacity was 75% and expiratory flow when vital capacity was 25%. The forced vital capacity, the first-second forced vital capacity and the maximum expiratory flow of the patients in the test group were higher after treatment than before (P<0.05) . The six-minute walking distance of the test group was greater than that of the control group after treatment (P<0.05) . After treatment, the scores of st George’s breathing questionnaire in the test group were lower than those in the control group (P<0.05) . The scores of quality of life questionnaire in the test group were higher than those in the control group after treatment (P<0.05) . Conclusion The comprehensive rehabilitation treatment of individualized exercise program improved the endurance and exercise ability of pneumoconiosis patients, improved the respiratory status and quality of life of pneumoconiosis patients in Huaibei Coal Mine, improved the lung function of pneumoconiosis patients, and improved the forced vital capacity of patients, but the small airway function has not been significantly improved.

A case of pituicytoma was observed in a Han-Wistar rat from the control group of a 2-year carcinogenicity study. No obvious abnormality were found in clinical observation and necropsy. Hematoxylin and Eosin (HE) staining results showed that nodular hyperplasia in the pars nervosa of the pituitary, which was well demarcated and compressed the adjacent normal tissue. The tumor cells were similar to the glial cells with round or oval nuclei, cytoplasm rich in eosinophilic or vacuole. The tumor cells differentiated well, with no obvious cell pleomorphism and visible mitotic figures. Some tumor cells were arranged in a pseudorosette formation. Immunohistochemical staining (IHC) analysis confirmed positive expression of Glial fibrillary acidic protein (GFAP) and S-100 protein. The tumor was diagnosed as the spontaneous benign pituicytoma combining the HE and IHC staining results.

【Objective】 To study the expression levels of suppressor of cytokine signaling 1 (SOCS1) and its clinical significance in hepatitis B virus (HBV)-related liver diseases. 【Methods】 For this study we enrolled 25 patients with chronic hepatitis B (CHB), hepatitis B cirrhosis, or HBV-associated chronic acute liver failure (HBV-ACLF), and 25 healthy controls. The expression levels of SOCS1 mRNA in peripheral blood mononuclear cells (PBMCs) were determined using the RT-PCR method. The levels of SOCS1 and interleukin-6 (IL-6) in the plasma of patients with chronic liver diseases and healthy controls were measured using the ELISA method. The relative expression levels of SOCS1, SOCS1 mRNA, and other laboratory test indicators such as HBV-DNA, alanine aminotransferase (ALT), aspartate aminotransferase (AST), prothrombin activity (PTA) and total bilirubin (TBil) were compared among the groups. Additionally, the correlation between the expression levels of SOCS1 mRNA and the aforementioned laboratory indicators was assessed. 【Results】 The expression levels of SOCS1 mRNA and serum SOCS1 were highest in the HBV-ACLF group, followed by the cirrhosis group, and lowest in the healthy control group, with statistically significant differences (F=109.65, P<0.001). The relative expression of SOCS1 mRNA was positively correlated with TBil (r=0.89, P<0.001), ALT (r=0.89, P<0.001), AST (r=0.84, P<0.001) and IL-6 (r=0.93, P<0.001), but negatively correlated with PTA (r=-0.89, P<0.001) and was not significantly correlated with HBV-DNA (P=0.28). 【Conclusion】 The expression levels of SOCS1 in patients with HBV-related chronic liver diseases can reflect the severity of the disease and show a significant correlation with indicators used to assess the severity of liver diseases.
