Paroxysmalnocturnalhemoglobinuria(PNH)isadefectdiseaseofacquiredclonal hematopoietic stem cel s. It can be expressed as hemolytic anemia, hemoglobinuria, and venous thrombosis. Cerebral venous sinus thrombosis (CVST) is a rare but serious complication of PNH. Here we report a PNH patient with CVST and reviewthe relevant literature. For patients who have the risk factors for CVST and neurological symptoms, such as headache and increased intracranial pressure, should early conduct brain imaging examination and make the diagnosis clear, and give an active treatment in the aspects of anticoagulation, dehydration, eliminating the causes of disease, and controling complications.

Objective To investigate the first decompression time of TR Band hemostasis after transradial percutaneous coronary intervention (TRI), provide evidence to support and guidance for clinical nursing practice. Methods By searching Cochrane Library, OVID, PubMed, Chinese biomedical literature service system(CBM),China National Knowledge Infrastructure(CNKI), VIP database(VIP), Wanfang database, the randomized controlled trials (RCTs),controlled clinical trials (CCT) and historical cohort study(HCT) of TR Band hemostasis after coronary artery intervention were collected and analyzed. Two reviewers used bias risk assessment tool according to Cochrane recommendation Handbook 5.0 to evaluate, Meta-analysis was carried out using RevMan 5.1.5 software. Results A total of 1 881 patients in 2 RCTs and 3 CCTs were included.Compared with the first decompression time 30 min, patients in 1 h group with limb swelling and pain incidence were statistically significant difference [ (OR=2.22, 95%CI 1.25-3.93, P<0.01) vs. (OR=1.63,95%CI 1.02-2.59, P < 0.05)], bleeding at the puncture sites or the operative limbnumbness or ecchymosis there was no significant difference [(OR=0.77,95%CI 0.35-1.71, P>0.05) vs.(OR=2.14, 95%CI 0.75-6.12, P>0.05)vs.(OR=11.73, 95%CI 0.64-215.74, P>0.05)];1h compared with 2 h patients with limbs, pain, hemorrhage rate had significant difference [(OR=0.09, 95%CI-0.13--0.05, P<0.01) vs. (OR=2.07, 95%CI 1.24-3.46, P<0.01)]; a comparison between 90 min and 2h, the limb pain and swelling incidence were statistically significant difference [(OR=2.77, 95%CI 1.82-4.23, P<0.01)vs.(OR=2.73,95%CI 1.41-5.28, P<0.01)], the puncture site bleeding, hematoma, ecchymosis rate and the operative limb numbness extent differences were no statistical significance [(OR=0.97,95%CI 0.61-1.54, P>0.05) vs. (OR=0.95, 95%CI 0.52-1.75, P>0.05)vs. (OR=0.96,95%CI 0.54-1.73, P>0.05)]. Conclusions 30 min decompression after TRI can reduce operative limb swelling and pain incidence rate. There is no obvious influence between puncture site bleeding and operative limb numbness.

Lin28 is a highly conserved RNA-binding protein that has an important role in human body development, metabolism, and tumorigenesis. Previous studies have found that the activation of Lin28 can suppress the maturity of let-7 miRNA in stem cells and promote the proliferation of stem cells by upregulating cell-cycle related genes, such as cyclins A and B. Other mechanisms underlying the activation of Lin28 can selectively block the processes of pre-let-7 miRNA in embryonic stem cells and ultimately promote tumori-genesis. In addition, Lin28 affects the occurrence, development, and prognosis of cancer by inhibiting the differentiation and maturation of miRNA and by moderating the expression of some cell-cycle related genes. Lin28 has an important function in the tumor's tolerance of chemotherapy and radiotherapy. We review the physiological function of Lin28 in tumors and its function in tumor treatment.

Objective To evaluate the effectiveness of TR Band hemostat in trans-radial coronary intervention patients.Methods The randomized controlled trials (RCTs) on the application of TR Band hemostat in trans-radial coronary intervention patients were collected through the databases such as the Cochrane Library,OVID,PubMed,CBM,VIP and Wanfang Data.The quality of studies was critically appraised and data were extracted by two reviewers independently,and Meta-analysis was conducted for the included studies.Results Five RCTs involving 5 028 patients were included.Meta-analysis showed that the application of TR Band hemostat in trans-radial coronary intervention patients could shorten the time of hemostasis by compression,reduce the incidence rate of skin lesions,improve the postoperative patients with comfort,but the efficacy was not significant in puncture site bleeding,hematoma and incidence of radial artery occlusion (RAO).Conclusions The application of TR Band hemostat in trans-radial coronary intervention patients can significantly decrease the incidence of oppression hemostasis time and reduce the incidence rate of skin lesions,improve the postoperative patients with comfort.It is worth being popularized.

Liposome is an artificially prepared spherical vesicle that has a phospholipid bilayer. Given that the basic structure of its biological membrane is also a lipid bilayer membrane, liposome shares similar structures with body cells Therefore, liposome has good biocompatibility and advantages such as biodegradability, low immunogenicity, and subtle toxicity. Liposome has been widely ap-plied as an effective drug carrier. Studies on liposome-encapsulated fluorescent dye on tumor tracing have been reported in recent years. Liposome can become a more advantageous transport carrier with continuous development of surface modification materials and prepa-ration methods. The long cycle, targeted liposome-encapsulated drugs, and fluorescent dye have become the focus of interest for several researchers. This article mainly discusses the application and progress of long cycle and targeted liposome in cancer research.

The incidence of restenosis and major adverse cardiovascular events were significantly less in the hyperbaric oxygen group than that in the control group (6.67% vs 22.58% for restenosis, and 8.82% vs 38.24% for major adverse cardiovascular events; P0.05). No severe adverse effect was found during hyperbaric oxygen therapy in the hyperbaric oxygen group. Conclusion Hyperbaric oxygen therapy is effective and safe in preventing restenosis after intracoronary stenting.

AIM: To explore the influence of Chrysanthemum morifolium Ramat on TNF-related apoptosis inducing ligand (TRAIL)-mediated apoptosis in human colon cancer cell line DLD-1 and its possible mechanism. METHODS: Adenovirus-mediated TRAIL gene AD/hTERT-gTRAIL was applied either alone or by combination with Chrysanthemum morifolium Ramat in human colon DLD-1 cell line. Cell growth and apoptosis were measured by inverted microscope, MTT method and flow cytometry. The expression of TRAIL mRNA, TRAIL-Rs mRNA and TRAIL protein expression after exposure to Chrysanthemum morifolium Ramat were measured by semi-quantitive RT-PCR and FACS, respectively. RESULTS: The suppression percentages and apoptotic rate of DLD-1 by Ad/hTERT-gTRAIL alone were 31.4% and 13.5%, respectively. Combination of TRAIL gene transfection with Chrysanthemum morifolium Ramat, the suppression and the apoptosis rate raised to 93.1% and 45.4%, respectively (P
