1 ? 25-dihydroxy-vitamin D3(1? 25 (OH)2 D3)induced differentiation of human promyelocytic leukaemia cells ( HL-60 ) into mature myeloid cells in vitro. The ratio of nuclei to cytoplasma decreased; Their nucleoli reduced; Cells became irrgular and extended the pseudopods. 1 ? 25 (OH ) 2 D3 caused significant increase of nitroblue tetrazolium ( NBT ) reduction and ?-non-specific acid esterase (?-NAE ) and acid phosphatase (ACP ) activities. These data and morphological characteristics suggest that HL-60 cells were conclusively identified as monocytes/macrophages. The histogram of DNA distribution ahylyzed by flow cytometry demonstrated G0 + G1 phase increased and S phase increased and S phase decreased remarkably after treatment with l?, 25 ( OH ) 2 D3 as compared with untreated cells.

Complete surgical resection is very important for the outcome of cancer treatment and prognosis.Radionuclide imaging and optical imaging are effective methods for intra-operative guidance of tumor exploration and resection because of their capability in accurate tumor localization and margin delineation.With the development of more specific molecular probes and more sensitive detectors,advanced imaging methods that combine the advantages of both optical and radionuclide imaging,such as Cerenkov luminescence imaging,will be expected to play a more important role as intra-operative navigating agents for surgical oncology in the near future.

MicroRNAs (miRNAs) are a novel class of small noncoding RNAs that regulate gene expression by targeting mRNAs for either cleavage or translational repression.Accumulated studies show that miRNAs aberrantly expressed in tumors are closely related with tumorogenesis and could be potential tumor biomarkers.It will be helpful in the diagnosis,prognosis and(or) predicting treatment response of tumor by imaging miRNAs expression.Several molecular imaging methods,including the optical imaging,radionuclide imaging and multimodality imaging,have been successfully used to visualize miRNAs,miRNAs,a new molecular imaging target,may explore a new field for tumor diagnosis and therapy.

Objective To investigate the effect of high-flux hemodialysis (HFHD) on advanced oxidation protein products (AOPPs) in maintenance hemodialysis (MHD) patients.Methods 40 MHD patients (MHD group),50 non-dialytic chronic kidney disease (CKD) patients (CKD group) and 31 healthy subjects undergoing health examination survey received AOPPs detection.After lowflux hemodialysis (LFHD) for 3 months,HFHD was performed in MHD group for 3 months.Plasma AOPPs and other biochemical indicators were tested at the end of 0,3 and 6 months.AOPPs levels were detected in HFHD and LFHD dialysates.Results Plasma AOPPs level was higher in MHD group than in CKD and control groups,and plasma AOPPs level was higher in CKD group than in control group.Compared with before LFHD in MHD group,AOPPs and triglyceride (TG) levels had no significant differences after LFHD for 3 months(t=0.831,-0.191,both P＞0.05),while plasma cholesterol (CHO) and β2 MG levels were increased in MHD group after LFHD for 3 months(t＝-2.697,10.39,P＜0.05 or 0.001).There were significant differences in plasma AOPPs,TG,β2-MG and CHO levels before versus after HFHD for 3 months (t=4.292,2.271,8.297 and 2.295,P ＜0.001 or 0.05).No AOPPs were detected in HFHD and LFHD dialysates.Conclusions Plasma AOPPs levels are increased in CKD patients.LFHD can not effectively eliminate AOPPs,while long term HFHD can decrease the plasma levels of AOPPs,TG and CHO,and reduce β2-MG accumulation.

Objective:To explore the possibility and methods of surgical treatment(ST) for huge primary liver cancer(HPLC).Methods:The clinical data of 86 HPLC were analyzed retrospectively and the main challenges as well as their counter measures during ST are concluded.Results:Among the 86 cases,there were 10 cases which complicated with portal vein(PV),and 5 cases with IVC thrombus respectively;there were 76 cases with HBV cirrhosis,2 HCV cirrhosis,there were 60 and 26 cases of primary and secondary hepatectomy in which included regular right(9 cases),left hemihepatectomy(8 cases)and combined hepatectomy(69 cases).Six cases received PV embolism before surgery.There were 10 and 5 cases of cancer thrombus extraction from PV and IVC respectively.In this group,81 patients were cured,and the perioperative mortality was 5.8%(5/86).The postoperative one—year survival rate for the patients was 77.9%.Conclusions:ST for HPLC is safe and acceptable.Full of preoperative assessment,careful intraoperative exploration,and surgical skill played a key roles.

OBJECTIVE:To explore the effects of ursodeoxycholic acid and adenosine methionine combined with polyene phos-phatidylcholine on related indicators of pregnancy with intrahepatic cholestasis(ICP). METHODS:Medical information of 90 ICP female were analyzed retrospectively and divided into control group(45 cases)and observation group(45 cases)according to drug use. Control group was given Ursodeoxycholic acid tablet 300 mg orally,3 times a day+Transmetil for injection 1 g added into 5%Glucose injection 250 mL intravenously,once a day. Observation group was additionally given Polyene phosphatidylcholine injec-tion 15 mL added into 5% Glucose injection 250 mL intravenously,once a day,on the basis of control group. Treatment course of 2 groups lasted for 2 weeks. The itching score,the levels of serum total bile acid(TBA),ALT and AST,pregnancy outcome and the occurrence of ADR were observed in 2 groups before and after treatment. RESULTS:Before treatment,there was no statistical significance in itching score,the levels of TBA,ALT and AST between 2 groups (P>0.05). After treatment,itching score,the levels of TBA,ALT and AST in 2 groups were significantly lower than before treatment,and the observation group was significant-ly lower than the control group,with statistical significance (P<0.05). The cesarean section rate,premature birth rate,fetal dis-tress rate and amniotic fluid rate of observation group were significantly lower than those of control group,with statistical signifi-cance(P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:Ursodeoxycholic acid,ademetionine combined with polyene phosphatidylcholine can effectively alleviate itching symptoms,liver function and pregnancy outcome of ICP patients,with good safety.

Objective To construct a database for the genetic polymorphism of 19 STR loci in Han population from Hainan province. To investigate the application of 19 STR loci in the paternity testing. Methods The genotypes of 462 unrelated individuals in Hainan were detected with GoldeneyeTM 20A PCR Amplification Kit. 19-STR database was acquired, analyzed and evaluated in 283 paternity testing cases. Results No deviations of allele frequency from Hardy-Weinberg equilibrium expectations were found for Chi-square test (P>0.05). Observed heterozygosity (Hobs) varied between 0.603 and 0.914, total discrimination power (TDP) of 19 STR loci was more than 0.999999999999999, cumulative probability of exclusion (CPE) for triplet cases was 0.999999994. In all 283 paternity testing cases, triplets and duos were 170 and 113 respectively; there were 36 (12.7%) excluded cases comparing to 247 confirmed cases (87.3%). 14 mutation events were observed, and all were one-step mutation. Conclusion 14 out of 19 loci showed highly polymorphic in Han population from Hainan, and 19 STR system has high cumulative probability of exclusion and can meet the needs of paternity test of the local region. But mutation should be paid special attention to.
