Copper is an essential metal element for human metabolism. Copper homeostasis can lead to inherited disorders of copper metabolism and also play an important role in tumor proliferation. In recent years, great progress has been made in the research and development of radioactive metal nuclide tracers, and molecular imaging quickly becomes a new inspection technology for detecting copper metabolism. 64CuCl 2 carries out PET imaging diagnosis of diseases with abnormal copper metabolism and tumors with high copper metabolism through real-time tracking of changes of copper ions in the body. At the same time, β - decay and electron capture of 64CuCl 2 have a therapeutic effect, and can be directly used for tumor nuclide therapy. Therefore, 64CuCl 2, as an integrated radiopharmaceutical for diagnosis and treatment, is the current research focus of molecular imaging. This article reviews 64CuCl 2 preparation, biological metabolism and its application in the diagnosis and treatment of abnormal copper metabolism diseases and tumors.

Objective To investigate the indications for interventional therapy of Budd-Chiari syndrome((B-CS)) and surgical treatment after stent failure. Methods A retrospective analysis of the clinical data of 21 patients with mistakes in treatment of B-CS by stent placement in inferior vena cava(IVC).Results (Among) the 21 cases with mistakes, the indications were inappropriately selected in 6 cases, the main hepatic vein was obstructed by the stent in 1 case, dilated accessory veins were occluded in 10 cases, the stent was (displaced) in 3 cases, and the stent failed to unfold in 1 case. Nineteen cases were converted to operation; of these patients, a shunt was performed in 18 cases, and radical excision of diaphragmatic web of IVC was done in 1 case. Operation was successful in all 19 cases. After shunt procedure in the 18 cases, the free portal pressure significantly decreased(P

Objective To study the complications and the outcome of different type of twin pregnancy. Methods Three hundred and thirty two cases of twins from 1981 to 2000 were analyzed retrospectively. Results The incidence of twins is 8.63%.The common complications were pregnancy induced hypertension, premature rupture of fetal membranes, anaemia, premature labor and postpartum hemorrhage. There were no differences between the monozygotic twins and dizygotic twins in the incidences of these complications. The incidence of one fetal death in monozygotic twins was higher than that of the dizygotic twins (P

Objective To investigate the effects of duration of active phase on delivery mode and pregnancy outcome.Methods Data of 417 women with abnormal active phase identified from 1744 term-birth,singleton,cephalic presentation primiparas who had tried vaginal delivery in Peking University First Hospital from January 1,2009 to December 31,2009 were retrospectively studied.Effects of different durations of protracted active phase on pregnancy outcomes were compared between women with vaginal delivery or cesarean section by Chi square test.Results The incidence of protracted active phase was 23.9％ (417/1744); and the incidence of prolonged active phase was 2.9％ (50/1744).There were 205 cases of cesarean section and 212 cases of vaginal deliveries.The incidence of neonates hospitalization in Department of Pediatrics in vaginal delivery group with active phase ≥6 h was higher than that of those with active phase ＜6 h [20.6％ (26/126) vs 8.1％ (7/86),x2 =6.07,P＜0.05].The incidence of intrauterine infection in cesarean section group with active phase ＜6 h were higher than that of those with active phase ≥6 h [22.7％ (30/132) vs 6.8％(5/73),x2 =8.37,P＜0.01].In vaginal group with protracted active phase before 6 cm of cervical dilation,the incidences of postpartum hemorrhage (4.8％,9/186),maternal complications (3.8％,7/186) and neonates hospitalization (15.6％,29/186) were similar with those after 6 cm of cervical dilation [6.2％ (1/16),x2=0.12; 0.0％ (0/16),x2=0.01 and 12.5％ (2/16),x2=0.00; all P＞0.05] respectively.In cesarean delivery group with cervical dilation ≥6 cm,the incidence of neonates hospitalization was higher than that of those with cervical dilation ＜6 cm [60.0％ (6/10) vs 19.9％ (34/171),x2 =8.83,P＜0.05].There were no difference in maternal age,gestational age,body mass index at delivery,volume of postpartum hemorrhage and neonatal birth weight between women with cesarean section whose protracted active phase ≥4 h or ＜4 h when cervical dilation at 3 cm (P＞ 0.05 respectively).The incidence of neonates hospitalization was low in women whose indication of cesarean section was protracted active phase (11.2％,9/80),while it was high when protracted active phase complicated with intrauterine infection (42.1％,16/38).Conclusions Protracted active phase with cervical dilation less than 6 cm might not need active management if neither the mother nor the fetus is compromised.The infants born vaginally should be closely monitored if the active phase is over 6 h.

Objective To develop an effective process for isolating and purifying haptoglobin ( Hp) from Cohn fractionⅣby a new ion exchange chromatography and to preliminarily identify and analyze the product of each purification step . Methods The fraction was first diluted and impurities were adsorbed with Rivanol .Then, the supernatant was treated with 50%ammonium sulfate.Finally, the precipitate was redissolved , and Hp was purified further with Q Sepharose Fast Flow chromatography .Native-PAGE was used to measure the activity of the haptoglobin-bound hemoglobin , while SDS-PAGE analysis and immunoblot were used for identification of the target protein .Results After pretreatment , some of the impuri-ties were removed from the Cohn fraction Ⅳ, and the target protein was enriched .In our case, the target protein was Hp and Hp2-2 was the main phenotype in the human plasma fraction Ⅳ.Target protein band and high purity were identified by SDS-PAGE.Immunoblot analysis further proved that this method could successfully isolate the target protein Hp , and the activity of 2.8 U/ml was measured by Native-PAGE method.Conclusion Haptoglobin is successfully isolated from human Cohn fractionⅣwith this method.The purification process is simple and suitable for scale-up production with a good prospect.

Objective To detect the expressions of circulating microRNAs (miRNAs) of peripheral whole blood in Alzheimer's disease (AD) and investigate the potential roles of the miRNAs as diagnostic bi omarkers for Alzheimer's disease.Methods Peripheral blood samples were obtained from 110 AD patients and 150 age-and gender-matched normal controls.The concentrations of seven candidate miRNAs,including miR-9,miR-29a,miR-29b,miR-101,miR-181c,miR-137and miR-126,were measured with a real-time quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) method.The data of two groups were collected and analyzed by SPSS 19.0 software.Results It was found that miR-29a (P=1.12×10-5) and miR-101 (P=6.24× 10-7) were markedly down-regulated in peripheral blood of AD patients compared with normal controls.In addition,logistic regression analysis revealed peripheral whole blood miR-29a/101 combination could be a potential biomarker of AD with better specificity (82％) and sensitivity (75％).Conclusions miR-29a/101 combination in peripheral whole blood may serve as a useful noninvasive diagnostic biomarker for AD.

Objective To investigate the causes,prevention and management principles of postoperative recurrence of Budd Chiari syndrome(BCS).Methods The clinical data of 223 postoperative recurrence BCS patients were analyzed retrospectively,including type Ia in 66 cases,type Ib in 48 cases,type II in 57 cases , type IIIa in 28 cases,and type IIIb in 24 cases. Of them,36 patients underwent two or more operations .Results Secondary operations were all successful.No patient died in the perioperative period. One hundred and eighty two patients were followed up for 6 months to 10 years.In 89.6% of the patients,the results were successful,but the recurrence rate after the reoperation was 6.0%,and 8 patients died postoperatively .Conclusions The main recurrent causes are that indications are not correctly selected and the operative technique is not correct. Correct classification,reasonable selection of the operation method, and adopting an interruptive,matress,and eversive suture for blood vessels anastomosis in the operation are important to prevent the recurrence of BCS.
