BACKGROUND Emergency contraception (EC) is using a drug or copper intrauterine device (Cu-IUD) to prevent pregnancy shortly after unprotected intercourse. Several interventions are available for EC. Information on the comparative effectiveness, safety and convenience of these methods is crucial for reproductive healthcare providers and the women they serve.(More)
Although recent evidence suggests that leptin can directly regulate a wide spectrum of peripheral functions, including fat metabolism, genetic examples are still needed to illustrate the physiological significance of direct actions of leptin in a given peripheral tissue. To this end, we used a technical knock-out approach to reduce the expression of leptin(More)
The mechanisms underlying leptin resistance are still being defined. We report here the presence in human blood of several serum leptin-interacting proteins (SLIPs), isolated by leptin-affinity chromatography and identified by mass spectrometry and immunochemical analysis. We confirmed that one of the major SLIPs is C-reactive protein (CRP). In vitro, human(More)
Hepatitis C virus screening was conducted among 8,226 residents 25-65 years of age in 4 counties of China; virus prevalence was 0.9%. A subsequent case-control study indicated blood transfusion (odds ratio [OR] 4.55), esophageal balloon examination (OR 3.78), and intravenous injection (OR 5.83) were associated with infection.
Personalized web search (PWS) has demonstrated its effectiveness in improving the quality of various search services on the Internet. However, evidences show that users' reluctance to disclose their private information during search has become a major barrier for the wide proliferation of PWS. We study privacy protection in PWS applications that model user(More)
The objective of this study was to describe trends in the incidence rates of primary liver cancer in a geographically defined Chinese population. Primary liver cancer cases (N=13 685) were diagnosed between 1981 and 2000 and identified by the Tianjin Cancer Registry. Age-adjusted and age-specific incidence rates were examined in both males and females.(More)
PURPOSE The benefit of adjuvant radiotherapy (RT) after surgical resection for extrahepatic cholangiocarcinoma has not been clearly established. We analyzed survival outcomes of patients with resected extrahepatic cholangiocarcinoma and examined the effect of adjuvant RT. METHODS AND MATERIALS Data were obtained from the Surveillance, Epidemiology, and(More)
BACKGROUND Non-motor symptom (NMS) differences between male Parkinson's disease (PD) and female PD, and between early-onset PD (EOPD) and late-onset PD (LOPD) in Chinese populations remain largely unknown. METHODS A total of 522 PD patients from Southwest China were included. Patients were assessed using the Non-Motor Symptom Scale (NMSS) and Unified PD(More)
OBJECTIVE This study used resting-state functional MRI (fMRI) to evaluate regional and network alterations in patients with Parkinson's disease (PD) with and without depression. METHOD We recruited 29 patients with PD with depression (PD-Dep), 30 patients with PD without depression (PD-NDep), and 30 normal controls. All participants underwent(More)
Retinoic acid receptors (RARs) are reported to mediate the effects of retinoid acid and participate in the maintenance of normal hippocampal function during embryonic and postnatal stages. RARalpha is the only one that has been reported to be continuously expressed among RARs in the CA1-CA3 areas of the hippocampus, at both the mRNA and the protein level.(More)
