The sequences of 5.8S rDNA and the flanking internal transcribed spacers (ITS1 and ITS2) were sequenced from hypha, fruit body and sclerotia of Grifola umbellata and its companion fungus. Their ITS sequences similarity was 99.36%. The results suggested that G. umbellata was closely related to its companion fungus.

Electrophysiology examination is an important technique in studying amblyopia, which mainly includes electrooculography( EOG), electroretinography ( ERG), visual evoked potential( VEP). This study does not only summarizes the definition, the mechanisms and the meaning of these indexes in the relevant research progress in recent years, but also makes a comment on the controversies among the relevant research conclusions.

Objective To investigate HLA-DPB1, DQB1 gene alleles and their correlation with autoantibodies in type 1 diabetes mellitus. Methods Sequence-based typing was used to determine the alleles of HLA-DPB1 and -DQB1 in 68 patients with type 1 diabetes and 50 healthy controls. Autoantibodies 〔glutamic acid decarboxylase antibody (GADA), islet cell antibody (ICA), insulin autoantibody (IAA)〕were detected by ELISA. Results Compared with the controls, the frequencies of DPB1*0402 and DQB1*0301 were significantly lower in type 1 diabetics (11.76%, 5.15% vs 30.00%, 22,00% respectively, P

Objective To prospectively evaluate the safety and therapeutic efficacy ofdalteparin in patients with high risk non-ST-elevation acute coronary syndromes (ACS) during percutaneous coronary intervention (PCI). Methods Atotal of 175 patients with high risk non-ST-elevation ACS were randomly assigned to 2 groups [dalteparin group and unfractionated heparin (UFH) group]. The patients in dalteparin group were given dalteparin at a dose of 5,000U subcutaneously soon after diagnosis and then an additional 60U/ kg intravenous bolus ofdalteparin before emergent PCI. Vascular access sheaths were removed immediately after PCI or coronary artery angiography; the patients in UFH group were given UFH intravenously at a dose of 25mgjust before PCI and an additional 65mg bolus was administered if angiographic findings showed that the patients were suitable for percutaneous transluminai coronary angioplasty (PTCA). Sheaths were removed at 4-6 hours after PCI; Results Eighty-three patients in dalteparin group underwent PCI while 82 patients in UFH group underwent PCI; anti-Xa activities of 52 patients in dalteparin group were measured. The average anti-Xa activity was (0.83±0.26) U/ml at 15 minutes after intravenous injection of dalteparin and anti-Xa>0.5U/ml was obtained in 96.1% of the patients; hematomas at puncture sites were significantly fewer in dalteparin group as compared with UFH group (2.3% vs 9. 2%, P < 0.05); none of the patients in 2 groups suffered major bleeding events. No death, acute arterial reocclusion or emergent revascularization events occurred at 30 days after PCI. Conclusions Our study demonstrated that early subcutaneous injection of dalteparin at a dose 5,000U after diagnosis and an additional 60U/kg intravenous bolus ofdalteparin before PCI is safe and efficacious for patients with high risk non-ST-elevation ACS undergoing emergent PCI

Objective:To assess whether familial occurrence has an influence on the morphological characteristics of patients with nonsyndromic cleft lip and/or palate (NsCL/P).Methods:A case-control analysis was performed on the morphological characteristics of familial group and sporadic group,using medical records of 1967 patients with NsCL/P treated in the Affiliated Stomatological Hospital of Nanchang University from 2002 to 2014.Results:164 (8.34%) cases presented a positive history of cleft in their families.The cleft types,the positive familial rate of cleft lip only (CLO),cleft lip and alveolar ridge(CLA),cleft lip and palate (CLP) and cleft palate only (CPO) were 8.11%,8.54%,6.19% and 9.65% respectively.A positive family history of NsCL/P was associated with 0.66 times risk of CPO (P =0.036,OR =0.66,95% CI 0.44-0.98) compared to those of CLO,CLA and CLP.In familial group of CLP,the lateral incidence of male patients was different from that of female patients (P < 0.001).There was no significant difference between familial group and sporadic group on birth weights,parental child-bearing age and clinical manifestations of patients.Conclusion:Familial occurrence might have an influence on cleft type,laterality and gender of the patients with NSCL/P.

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.
