·Hemophilia is a rare disorder that occasionally has visual symptoms after diagnosis. The authors present a case in which visual symptoms led to the initial diagnosis, a 22-year-old man who represented with spontaneous fundal haemorrhage. There is no history of bleeding and trauma. The fundal haemorrhage was absorbed significantly without any treatment after 3 months follow-up. Hemophilia A was found to be the causative disorder in this previously healthy man. The authors present a rare case in which unilateral visual complaints led to the diagnosis of hemophilia A. Thus, though uncommon, hemophilia should be considered in the differential diagnosis of otherwise unexplained fundal haemorrhages.

Objective To investigate the clinical effects of gastric bypass( GBP) on type 2 diabetes mel-litus(type 2 diabetes mellitus, T2DM)patients with different body mass index(BMI).Methods T2DM patients undergoing GBP from Sep.2012 to Jul.2013 were divided into 2 groups:obese group( BMI≥28 kg/m2 , 16 ca-ses)and overweight group(BMI<28 kg/m2,21 cases).Changes of fasting plasma glucose(FPG), insulin resist-ance index(HOMA-IR)and insulin stimulation release(INS), C peptide release, BMI, glycosylated hemoglobin ( HbA1c) at 3 and 6 months after surgery were observed.Results INS and C peptide improved 3 months after surgery(P<0.05),and they were close to normal at 6 months after surgery.HbA1c significantly decreased 3 months after surgery compared with that before surgery( P<0.05) and it was close to normal at 6 months after sur-gery.Patients in obese group had significantly declined weight 3 months after surgery compared with that before surgery, and reached the steady state 6 months after surgery.15 cases(93.7%) in the obese group had BMI<25 kg/m2 , and the difference had statistical significance ( P<0.05 ) .Patients in the overweight group had their weight declined but no statistical difference was found(P>0.05).Blood sugar in the obese group decreased with different degrees at 3 and 6 months after surgery.The effective rate was 92%for the obese group and 78%for the overweight group.The overall effective rate was 90%.Conclusion GBP has significant therapeutic value for T2DM patients with different BMI, especially for patients in obese group, which is worth of clinical promotion.

Chinese materia medica resource (CMM resource) is the foundation of the development of traditional Chinese medicine. In the study of sustainable utilization of CMM resource, adopting innovative theory and method to find new CMM resource is one of hotspots and always highlighted. Pharmacophylogeny interrogates the phylogenetic relationship of medicinal organisms (especially medicinal plants), as well as the intrinsic correlation of morphological taxonomy, molecular phylogeny, chemical constituents, and therapeutic efficacy (ethnopharmacology and pharmacological activity). This new discipline may have the power to change the way we utilize medicinal plant resources and develop plant-based drugs. Phylogenomics is the crossing of evolutionary biology and genomics, in which genome data are utilized for evolutionary reconstructions. Phylogenomics can be integrated into the flow chart of drug discovery and development, and extends the field of pharmacophylogeny at the omic level, thus the concept of pharmacophylogenomics could be redefined in the context of plant pharmaceutical resources. This contribution gives a brief discourse of knowledge pedigree of pharmacophylogeny, epistemology and paradigm shift, highlighting the theoretical and practical values of pharmacophylogenomics. Many medicinally important tribes and genera, such as Clematis, Pulsatilla, Anemone, Cimicifugeae, Nigella, Delphinieae, Adonideae, Aquilegia, Thalictrum, and Coptis, belong to Ranunculaceae family. Compared to other plant families, Ranunculaceae has the most species that are recorded in China Pharmacopoeia (CP) 2010. However, many Ranunculaceae species, e. g., those that are closely related to CP species, as well as those endemic to China, have not been investigated in depth, and their phylogenetic relationship and potential in medicinal use remain elusive. As such, it is proposed to select Ranunculaceae to exemplify the utility of pharmacophylogenomics and to elaborate the new concept empirically. It is argued that phylogenetic and evolutionary relationship of medicinally important tribes and genera within Ranunculaceae could be elucidated at the genomic, transcriptomic, and metabolomic levels, from which the intrinsic correlation between medicinal plant genotype and metabolic phenotype, and between genetic diversity and chemodivesity of closely related taxa, could be revealed. This proof-of-concept study regards pharmacophylogenomics as the updated version of pharmacophylogeny and would enrich the intension and spread the extension of pharmacophylogeny. The interdisciplinary knowledge and techniques will be integrated in the proposed study to promote development of CMM resource discipline and to boost sustainable development of Chinese medicinal plant resources.

The aim of this study was to detect the localization and level of tyrosine phosphorylated proteins during in vitro capacitation of guinea pig sperm. Sperm from mature guinea pigs were incubated in modified TALP under 5% CO_2 in air at 37 ℃. The capacitation effect was assessed by chlortetracycline (CTC) staining. Western blotting and indirect immunofluorescence were used to analyze the level and localization of tyrosine phosphorylation. The results showed that guinea pig sperm underwent a time-dependent increase in protein tyrosine phosphorylation during the in vitro capacitation and the percentage of protein tyrosine phosphorylated sperm increased from 36% to 92% from the beginning of incubation to 7h incubation. Also, there was a shift in the site of phosphotyrosine-specific fluorescence from the head of sperm to both the head and the flagellum of sperm. Moreover, there were three proteins phosphorylated in this experiment. After 0 to 0.5h incubation, the protein of 40kDa was detected by anti-phosphotyrosine monoclonal antibody, and the intensity of this protein increased in the following incubation. Then, after 1h incubation, another protein of 80kDa was found and the level of this protein reached the highest point at 3h. Also, in 3h incubation, a protein of 45kDa was detected and the intensity of this protein increased in the following incubation.

Objective To investigate the techniques and influence factors for the respiratory navigator echo triggered whole-heart coronary MR angiography(WH-CMRA)and evaluate its application in visualizing coronary arteries and the image quality.Methods Ninety two volunteers were acquired with WH-CMRA at 3 T MR scanner using respiratory navigator-echo gated TFE sequence.Imaging quality was visually graded as 0—Ⅳ grade according to the visual inspection,average length,diameter and sharpness of coronary arteries.The correlation between the imaging quality and respiratory pattern,heart rate and navigator efficiency was analyzed.Results The imaging quality in 92 cases was that 28 were graded as Ⅳ, 53 were graded as Ⅲ,9 were graded as Ⅱ and 2 were graded as Ⅰ.The successful rate of scan was 88% (81/92).The imaging quality is mainly graded as Ⅳ when the heart rate was less than 75 beats per minute (bpm)and the sharpness of vessel was(48?11)%.When heart rate was more than 75 bpm,the image quality was mostly graded as Ⅲ and the sharpness was(33?15)%.The correlation between heart rate and imaging quality score was negative(r=-0.726,P0.05).Conclusion 3 T WH-CMRA technique could facilitated the visualization of whole coronary arteries at free breathing but having indications on heart rate.
