Objective To study the neuroprotective effects of citicoline(CC) on the toxicity induced by 6-OHDA towards dopaminergic mesencephalic neurons in primary culture-Parkinson′s disease(PD) model in vitro and its mechanism. Methods Mesencephalic neurons in culture were prepared from embryonic 15-day Wistar rats.Cultures were treated for 6,8,10 d with various concentrations of CC(2,1,0.1,0.01 and 0.001 mmol?L~(-1)).At 11th day,the cultures were co-treated with the toxin 6-OHDA(50 ?mol?L~(-1)) for 0.5 h,the cells were collected.Seven groups were categorized as follows:CC(2,1, 0.1,0.01 and 0.001 mmol?L~(-1)) +6-OHDA,control and(6-OHDA) group.The cell viability was evaluated with MTT assay.Intracellular free Ca~(2+),[Ca~(2+)]i,was labeled by using the fluorescent dye Fluo3-AM and detected by flow cytometer.By measuring the intracellular Rhodamine(123 fluorescence) density with flow cytometer,mitochondrial membrane potential(MMP) was evaluated.(Results Cultures) were treated with 2,1 and 0.1 mmol?L~(-1) CC,the viability of cell was increased(P

Objective To evaluate the clinical value of fast detection of high sensitivity C-reaction protein(hs-CRP)in distinguis-hing between transudate and exudate.Methods 100 cases of patients were enrolled in the investigation.The levels of TP,LDH, GLU in serum and pleural effusion respectively,as well as the level of hs-CRP in the pleural effusion.Results According to Light standard,82 cases of patients were diagnosed as transudate(transudate group)and 18 cases of patients were diagnosed as exudates (exudates group).The sensitivities of Rivalta test,TP(pleural effusion)/TP(serum)and LDH(pleural effusion)/LDH(serum) were 83.14%,80.49% and 79.27%,respectively.Hs-CRP showed 84.15% sensitivity and 27.78% specificity at a cutoff value of 5 mg/L.TP(pleural effusion)/TP(serum)and LDH(pleural effusion)/LDH(serum)had the highest specificities,and both were 100.00%.The levels of LDH(pleural effusion)/LDH(serum)and hs-CRP in transudate group were significantly higher than those in exu-dates group(P<0.05).Combined detection of hs-CRP,TP(pleural effusion)/TP(serum)and LDH(pleural effusion)/LDH(serum)had the highest specificity (100.00%).Conclusion The fast detection of hs-CRP in pleural effusion is sensitive,combining with other tests can prove its specificity.The fast assay of hs-CRP has special clinic value in the distinguish between exudate and transudate.

Objective_To study the significance of fascin protein expression in ductal intraepithelial neoplasia ( DIN) and invasive ductal carcinoma ( IDC) .Methods_Thirty cases of usual ductal hyperplasia ( UDH) , 30 ca-ses of flat epithelial atypia (FEA,DIN1a), 15 cases of atypical ductal hyperplasia (ADH,DIN1b), 2 cases of DCIS grade1(DIN1c),10 cases of DCIS grade2(DIN2)and 18 cases of DCIS grade3(DIN3)were immunohisto-chemically investigated using monoclonal antifascin antibody and compared with 120 cases of invasive ductal carci-noma (IDC).Results_Fascin protein expression was not found in normal breast tissue, UDH, FEA (DIN1a), ADH(DIN1b),DCIS grade1(DIN1c)and DCIS grade2(DIN2),but only seen in 2 of 18 cases of DCIS grade3 (DIN3)(11.1%), and 18 out of 120 cases of IDC (15%).Fascin protein expression was correlated with ER neg-ative( P<0.05) , PR negative( P<0.05) , tumor grade( P<0.05) and axillary lymph node status( P<0.05) , but not correlated with age,location,tumor sizeand HER2 expression.Conclusions_Fascin protein expression seems to be a late event, usually present in carcinoma.Targetting the fascin pathway may be a noval therapeutic strategy of mammary carcinoma.

Objective To evaluate the clinical value of combined detection of serum CEA, CA125,CA153 and CA199 in lung cancer diagnostec. Methods The serum level of CEA,CA125,CA153 and CA199 in 58 patients with lung cancer,38 patients with benign lung diseases and 40 healthy persons were determinated by Chemiluminesent immunoassay. The data were analyzed to evaluate the diagnostic value of the combination use of four markers. Results The serum levels of CEA,CA125,CA153 and CA199 in lung cancer group were 5.6 (1.0-619. 0) μg/L,124. 5 (5.3 - 994. 8) U/ml,14.4(3. 1 - 800. 0) U/ml and 21.8(2.0 - 1200.0) U/ml respectively ;The serum levels of CEA, CA125, CA153 and CA199 in benign lung diseases were 1.9 (0. 6 -14.4) μg/L, 17. 7 ( 1.8 - 303.6 ) U/ml, 6. 8 ( 2. 4 - 20. 1 ) U/ml and 9. 3 ( 2. 0 - 82. 6 ) U/ml respectively. The serum levels of CEA, CA125, CA153 and CA 199 in healthy controls were 1.4 (0. 6 - 5.0 ) μg/L, 9.6 (4. 4 -36. 5 ) U/ml,6. 6 (3.8 - 19. 9) U/ml and 6. 4 (2.0 - 58. 1 ) U/ml respectively. The levels of markers in the lung cancer group were significantly higher than those in patients with benign lung disease and healthy controllers (Ps ＜ 0. 01 ). The sensitivity of combined measurement was 94. 8%, significantly higher than a single measurement ( CEA 48. 3% ,CA125 75.9% ,CA153 20.7% ,CA199 31.0% ,Ps ＜0. 01 ). Conclusion The combined detection of CEA, CA125, CA153 and CA199 can significantly improve detection sensitivity of lung cancer and might provide valuable laboratory proof for early diagnosis of lung cancer.

AIM:To establish the endoplasmic reticulum stress ( ERS) cell model in vascular smooth muscle cells ( VSMCs) of Sprague-Dawley (SD) rats.METHODS:Under sterile condition, the coronary arteries were isolated from SD rats .The primary VSMCs were cultured by tissue-sticking method , and observed the basic morphological characteristics under optical microscope .The marker proteins of VSMCs including α-smooth muscle actin (α-SMA) and smooth muscle myosin heavy chain ( SM-MHC) were identified by immuno-fluorescence technique .VSMCs were treated with thapsigargin (0.5, 1 and 2 μmol/L) for 24 h, and the expression levels of binding immunoglobulin protein (BiP) and C/EBP homologus protein (CHOP), the marker molecules of ERS, were detected using Western blotting.RESULTS:VSMCs climbed out from coronary artery tissues after about six days , and the cells had a nice state and formed the VSMC-like typical peak valley.The results of immunofluorescence technique show that the marker proteins of VSMCs ,α-SMA and SM-MHC were expressed significantly .The results of Western blotting show that the protein expression levels of BiP and CHOP were increased by thapsigargin in a dose-dependent manner .CONCLUSION:VSMCs can be successfully cultured by tissue-sticking method and built the ERS model induced by thapsigargin .

Objective To explore the role of serum levels of Klotho protein and fibroblast growth factor(FGF)-23 in patients with chronic kidney disease(CKD).Methods A total of 160 patients with CKD were recruited into CKD group in this study,160 healthy controls were selected in the control group from March 2014 to March 2016.Basic clinical data,blood biochemical index,serum level of Klotho protein and FGF-23 were analyzed and compared between the two groups.Results The hemoglobin,serum albumin,blood calcium,glomerular filtration rate,Klotho protein levels in the CKD group were lower than those in the control group,and the serum creatinine,blood urea,blood serum phosphorus and FGF-23 were higher than those in the control group(P<0.05).With the progress of CKD stages,hemoglobin,glomerular filtration rate,Klotho protein levels gradually decreased,serum creatinine,blood urea,blood serum phosphorus,FGF-23 level increased(P<0.05).The levels of FGF-23 were negatively related to hemoglobin,glomerular filtration rate,Klotho(r=-0.584,0.692,-0.724)and were positively correlated to serum creatinine,blood urea,blood serum phosphorus(r=0.814,0.703,0.527).The levels of Klotho protein were positively related to hemoglobin,glomerular filtration rate(r=0.612,0.685),and were negatively correlated to serum creatinine,blood serum phosphorus,blood urea,FGF-23(r=-0.720,-0.690,-0.519,0.724).Conclusion High concentrations of FGF-23 and Klotho protein with low concentration were not only related to calcium phosphate metabolic disorders of patients with CKD,and were also associated with the prognosis of patients with CKD,which might be early biomarkers and predictor in patients with CKD.
