ABSTRACT

To explore roles of expressions of EHD2 and E-cadherin in clear cell renal cell carcinoma (ccRCC).
 Methods: Four couples of fresh ccRCC tissues and adjacent non-cancerous tissues were collected to evaluate the expression of EHD2 and E-cadherin protein by Western blotting. A total of 65 paraffin-embedded renal ccRCC tissues were collected, and immunohistochemical assay was used to detect the expression of EHD2 and E-cadherin in the samples. The correlation between their expression and clinical and pathological indicators of ccRCC was analyzed, and the relationship between EHD2 and E-cadherin proteins and prognosis for patients with ccRCC was also explored.
 Results: The results of Western blotting showed that the expression levels of EHD2 and E-cadherin were low in 4 ccRCC tissues compared with the adjacent noncancerous tissues. Immunohistochemical results revealed that the expressions of EHD2 and E-cadherin were higher in the localized ccRCC tissues than those in the metastatic ccRCC tissues; the expression levels of EHD2 and E-cadherin were decreased, while the TNM staging and Fuhrman grade were increased (P<0.05 or P<0.01). There was positive correlation between the expressions of EHD2 and E-cadherin in ccRCC (r=0.390, P<0.01). The progression-free survival in ccRCC patients with lower expression of both EHD2 and E-cadherin was better than that in ccRCC patients with higher expressions of EHD2 and E-cadherin (P<0.05). 
 Conclusion: The low expressions of EHD2 and E-cadherin are the potential indicators for the ccRCC patients with poor prognosis.

ABSTRACT

Objective To observe the clinical efficacy of self-prescribed Guchong Decoction combined with Ferroids for the treatment of iron deficiency anemia (IDA)patients with unconsolidation of thoroughfare and conception vessels. Methods A total of 70 IDA patients with unconsolidation of thoroughfare and conception vessels were randomized into treatment group and control group,35 cases in each group. The control group was given oral use of Ferroids, and the treatment group was treated with self-prescribed Guchong Decoction combined with Ferroids. One month constituted a treatment course,and both groups were treated for 2 courses. Before and after treatment,we compared the parameters of blood routine test for red blood cells(RBC),hemoglobin (HGB), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), MCH concentration (MCHC),white blood cells(WBC)and platelets,as well as reticulocytes(Ret)and iron metabolism indexes including serum iron(SI),serum ferritin(SF),and total iron-binding capacity(TIBC). The adverse reaction was monitored during the treatment. After treatment,both western medicine clinical efficacy and traditional Chinese medicine (TCM)syndrome clinical efficacy of the two groups were evaluated. A 3-month follow-up was carried out after treatment to evaluate the recurrence rate. Results(1)Drop-out occurred in one case from the treatment group and in 2 cases from the control group because of short-term medication suspension.(2)After treatment for 2 months, western medicine clinical cure rate of the treatment group was 82.4% and that of the control group was 60.6%, and TCM syndrome clinical cure rate of the treatment group was 94.1% and that of the control group was 51.5%,the difference being significant(P < 0.05 or P < 0.01).(3)The levels of RBC,HGB,Ret, MCV, MCH, MCHC, and WBC of the two groups were obviously increased after treatment (P < 0.01), and PLT level was markedly decreased (P < 0.01)as compared with those before treatment,but the inter-group differences after treatment were insignificant (P > 0.05). (4)After treatment,iron metabolism indexes of SF and SI of the two groups were significantly increased (P < 0.01), and TIBC of the treatment group was significantly decreased (P < 0.01). The treatment group had stronger effect on increasing SF and SI and on decreasing TIBC than the control group (P < 0.05 or P < 0.01). (5)The incidence of adverse reaction and the recurrence rate in the treatment group were lower than those of the control group,the difference being significant (P< 0.01). Conclusion Guchong Decoction combined with Ferroids is effective for the treatment of IDA with unconsolidation of thoroughfare and conception vessels through relieving symptoms rapidly, reducing gastrointestinal adverse reaction,and decreasing recurrent rate.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the HER22 expression in children with ETV6/RUNX1 (E/R)-positive acute lymphoblastic leukemia(ALL) and to investigate the relationship between the HER2 expression and clinical features.</p><p><b>METHODS</b>Thirty-seven newly diagnosed E/R-positive ALL children and 6 controls (4 cases of ITP and 2 healthy children) were selected in Institute of hematology and blood disease hospital. The 37 patients were divided into standard risk (SR), intermediate risk(IR), high risk(HR) groups according to risk stratification; and they were divided into relapse and non-relapse groups according to follow-up result. The CD10CD19 cells were sorted by flow cytometry. The mRNA was extracted from these cells. Real-time fluorescent quantitative PCR was used to detect the expression level of HER2.</p><p><b>RESULTS</b>Among the 37 cases, 51.35% (n=19) were boys and 48.65% (n=18) were girls and their median age was 4.72 (1.72-11.99) years old. Among the 6 controls, 50% (n=3) were boys and 50% (n=3) were girls and the median age was 5.24 (1.53-13.17) years old. The expression level of HER2 in E/R-positive ALL patients were lower than that in controls (P<0.05). Although the difference of HER2 expression level between the 2 groups failed to achieve statistical significance, the expression level of HER2 in relapse patients were significantly lower than that in non-relapse patients, and the HER2 expression in HR group patients were lower than that in SR and IR groups. In addition, there was no significant correlation between the expression level of HER2 and the sex, age, initial white blood cell count, blast cell percentage and the level of LDH (P>0.05).</p><p><b>CONCLUSION</b>The expression level of HER2 in E/R ALL patients is lower than that in controls, and in relapse group lower than that in non-relapse patient. Thus, HER2 may play important roles in the pathogenesis and relapse mechanism of pediatric E/R-positive ALL patients.</p>

ABSTRACT

OBJECTIVE Non-alcoholic fatty liver disease(NAFLD) encompasses a series of patho-logic changes ranging from steatosis to steatohepatitis,which may progress to cirrhosis and hepatocel-lular carcinoma.The purpose of this study was to determine whether Ganoderma lucidum polysaccha-ride peptide (GLPP) has therapeutic effect on NAFLD. METHODS ob/ob mouse model and ApoC3 transgenic mouse model were used for exploring the effect of GLPP on NAFLD. Key metabolic path-ways and enzymes were identified by metabolomics combining with KEGG and PIUmet analyses and key enzymes were detected by Western blotting. Hepatosteatosis models of HepG2 cells and primary hepatocytes were used to further confirm the therapeutic effect of GLPP on NAFLD. RESULTS GLPP administrated for a month alleviated hepatosteatosis, dyslipidemia, liver dysfunction and liver insulin resistance. Pathways of glycerophospholipid metabolism, fatty acid metabolism and primary bile acid biosynthesis were involved in the therapeutic effect of GLPP on NAFLD. Detection of key enzymes revealed that GLPP reversed low expression of CYP7A1,CYP8B1,FXR,SHP and high expression of FGFR4 in ob/ob mice and ApoC3 mice. Besides, GLPP inhibited fatty acid synthesis by reducing the expression of SREBP1c, FAS and ACC via a FXR-SHP dependent mechanism. Additionally, GLPP reduced the accumulation of lipid droplets and the content of TG in HepG2 cells and primary hepato-cytes induced by oleic acid and palmitic acid. CONCLUSION GLPP significantly improves NAFLD via regulating bile acid synthesis dependent on FXR-SHP/FGF pathway, which finally inhibits fatty acid synthesis,indicating that GLPP might be developed as a therapeutic drug for NAFLD.

ABSTRACT

Objective To investigate the association of chest pain patients with primary level in high-sensitivity troponin T (hs-cTnT) level no more than 14 ng/L in the onset of acute myocardial infarction in pa-tients with chest pain. Methods We enrolled 3 096 participants from January 2012 to December 2013 in West China Hospital, Sichuan University. All patients were classified two groups (hs-cTnT > 14 ng/L, hs-cTnT ≤14 ng/L and no ischemia on ECG) according to hs-cTnT levels and ECG. We evaluated the risk of myocardial in-farction and death and negative predictive value in 30 days. Results Thirty-seven patients were diagnosed in having acute myocardial infarction (AMI) and 4 patients were dead in the hs-cTnT > 14 ng/L group in 30 days in the absolute risk 2.35(1.86-2.74) and 0.29(0.12-0.53); 9 patients were diagnosed as having AMI and no patients were dead in the hs-cTnT ≤ 14 ng/L group in 30 days in the absolute risk 0.58 (0.42-0.74). Conclu-sion Chest pain patients whose primary levels no more than 14 ng/L in hs-cTnT with no ischemia on ECG can be ruled out AMI in negative predictive value 99.6%. the levels of hs-cTnT which were dynamic monitored at least 5 h and still no more than 14 ng/L can rule out AMI directly.

ABSTRACT

Objective To explore effect of CYP3A4 gene polymorphism and genetic testing on the efficacy of fentanyl in patients with extensive burns.Methods A prospective randomized controlled study, 149 patients with extensive burns were picked from Feburary to July in 2015.Patients were randomly divided into matched group ( n=56 ) and experimental group ( n=93 ) . The matched group was treated with fentanyl 5 g/kg to finish implementation of anesthesia induction.Depends on the gene detection results, the patients in experimental group were treated with 6 g/kg, 5 g/kg or 4 g/kg fentanyl.The VAS score at different time after operation in the experimental group and the control group were compared , and the dosage of fentanyl was observed.Patients whose VAS score was greater than 7 should treated with intramuscular injection of pethidine 100 mg, recorded all patients with pethidine,s additional cases and the times.At the same time, the adverse reactions of the two groups were recorded before and after hospital discharge. ResuIts The score of VAS was not significantly different after wake up immediatly after the surgery , and the score of VAS was significantly lower in the experimental group patients in 6h,12h after the surgery (P<0.05).The dosage of fentanyl in the experimental group and the number of the cases and the times were significantly decreased (P<0.05).The adverse reactions after the surgery such as nausea, vomiting, itching, drowsiness, and adverse reactions were significantly lower in the experimental group (P<0.05).ConcIusion CYP3A4 gene detection in patients with large area of burn in the individual drug use is important, because of patients’ genotype adjusting fentanyl dosagecan, it enhances significantly the analgesic effect, reduces the amount of drug use, and effectively reduces the adverse reactions.
