Abstract
Bromodomain-containing protein 4 (BRD4) is the most well-studied BET protein that is important for the innate immune response. We recently revealed that targeting BRD4 triggers apoptosis in tumor-associated macrophages, but its role in synovial macrophages and joint inflammation is largely unknown. Herein, we demonstrated that BRD4 was highly expressed in the iNOS-positive M1 macrophages in the human and mouse osteoarthritis (OA) synovium, and conditional knockout of BRD4 in the myeloid lineage using Lyz2-cre; BRD4flox/flox mice significantly abolished anterior cruciate ligament transection (ACLT)-induced M1 macrophage accumulation and synovial inflammation. Accordingly, we successfully constructed apoptotic body-inspired phosphatidylserine-containing nanoliposomes (PSLs) loaded with the BRD4 inhibitor JQ1 to regulate inflammatory macrophages. JQ1-loaded PSLs (JQ1@PSLs) exhibited a higher cellular uptake by macrophages than fibroblast-like synoviocytes (FLSs) in vitro and in vivo, as well as the reduction in proinflammatory M1 macrophage polarization. Intra-articular injections of JQ1@PSLs showed prolonged retention within the joint, and remarkably reduced synovial inflammation and joint pain via suppressing M1 polarization accompanied by reduced TRPA1 expression by targeted inhibition of BRD4 in the macrophages, thus attenuating cartilage degradation during OA development. The results show that BRD4-inhibiting JQ1@PSLs can targeted-modulate macrophage polarization, which opens a new avenue for efficient OA therapy via a "Trojan horse".

Abstract
Pancreatic cancer is characterized by rapid onset, high malignancy and high mortality, thus its early diagnosis is effective for improving the survival rate of patients. To discuss the values of detection of carbohydrate antigen (CA) 50, CA242 and CA199 in the diagnosis of pancreatic cancer, this study randomly selected 112 patients who were confirmed as having stage Ia~IIb pancreatic ductal adenocarcinoma (PDAC) in the Shandong Provincial Hospital, China, from May 2012 to May 2013 as a malignant group. One hundred patients with benign pancreatic lesions and 90 healthy people were selected in the same period as a benign group and a healthy control group, respectively. The levels of serum CA199, CA242 and CA50 were detected using electrochemiluminescence. Results demonstrated that the levels of serum CA199, CA242 and CA50 of the malignant group were significantly higher than those of the benign group and the healthy control group (P=0.001; P=0.003; P=0.000). The positive rate of the tumor markers of the malignant group was higher than that of the benign group and the healthy control group, and the differences had statistical significance (P=0.006; P=0.004; P=0.005). In the malignant group, sensitivity of CA199 was the highest (81.42%) as was the specificity of CA242 (80.14%). The detection of two or more markers could improve sensitivity (joint detection based on parallel tests) and specificity (joint detection based on serial tests). Thus the levels of serum tumor markers including CA199, CA242 and CA50 could be used as the assisted indicators for the diagnosis of early-stage PDAC. Joint detection of the three tumor markers is of great significance to improve the diagnostic sensitivity and accuracy of early PDAC.

Abstract
OBJECTIVE To investigate treatment effects of levonorgestrel-releasing intrauterine system (LNG-IUS) for adenomyosis with menorrhea in a prospective study. METHODS From December 2006 to December 2014, patients of symptomatic adenomyosis diagnosed by transvaginal ultrasound in outpatient or inpatient clinics of Peking Union Medical College Hospital were given the treatment of LNG-IUS. Before and after placement of LNG-IUS, all the patients' parameters were recorded prospectively, including scores of menstruation blood loss, carrying status of IUS, symptoms and scores of dysmenorrhea, biochemical indicators, physical parameters, menstruation patterns and adverse effects. Changes of pictorial chart scores of menstruation and distribution of anemia during follow-up were analyzed. RESULTS Totally 1 100 women meets inclusion criteria, among which 618 cases (56.18%, 618/1 100) had severe menorrhea, with median follow-up period of 28 months (range 1- 60 months), and accumulative carrying rate of 66% at 60 months follow-up. After placement of LNG-IUS, compared with baselines, pictorial chart scores and ratio of menorrhea had decreased significantly (all P<0.01), the scroes of menstruation were 157±34, 94±35, 70±33, 67±18, 67±20, 65±19, 66±19, 65±21 at 0, 3, 6, 12, 24, 36, 48 and 60 months respectively. During 24 months after placement of LNG-IUS, pictorial chart scores and distribution of anemia had improved significantly compared with preceding period (all P<0.01). We found no dependent factors predicting improvement of pictorial chart scores of menorrhea, which was neither relevant with simultaneous changes of menstruation patterns nor adverse effects (all P>0.05). CONCLUSIONS LNG-IUS is effective for adenomyosis of menorrhea. Improvement of menstruation blood loss is independent on patients characters, menstruation patterns or adverse effects.

Abstract
Hepatitis C virus (HCV) infection represents a serious public health problem worldwide. Development of new therapeutics against HCV has been hampered by the lack of a small-animal model. Until now, it has been unclear which host factors influence the HCV infection. It was known that human CD81 (hCD81) or low-density lipoprotein receptor (hLDLR), the putative HCV receptors, induce concentration of viral particles on the cell surface. In this study, recombinant plasmids containing hCD81 or hLDLR genes were transfected to mouse hepatoma Hepa 1-6 cells and transgenic cell lines expressing hCD81 (hCD81/1-6 cell line) or hLDLR (hLDLR/1-6 cell line) on their surface have been established. HCV infection of these cell lines showed that the virus was bound, entered the cell, and replicated inside the cell. This finding is essential for the development of mouse model for the study of HCV replication in vivo.
