Results The incidence of multiple plaques in carotid artery was much higher in CI group than in C group and CAD group(P

Objective To study the anatomy of superficial palmar digital veins in fingertip,and explore the clinical application of superficial palmar digital veins as venous drainage in fingertip replantation.Methods One hundred fingers were studied with three methods: microanatomy,sectional anatomy,and X-ray.According to microanatomical observation,thirteen fingers in 10 cases with fingertip amputations and dorsal veins defect were replanted by anastomosis of palmar digital veins to reconstruct the venous drainage of the amputated digits. Results ( 1 ) 1 to 3 tiny superficial palmar digital veins can be found at the level of the onychorrhiza.The average diameters of the superficial palmar digital veins were 0.2-0.5 mm.(2)In clinical practice,13 replanted fingers were survived.After 3-18 months following-up,the appearance and function were satisfactory. Conclusion The distribution of the palmar digital veins was in some pattern.Anastomosis of the superficial palmar digital veins can not only improve the success rate of the fingertip replantation,but also avoid the complications of the other venous drainage methods.

Objective To investigate the effect of bifidobacteria on dextran sulphate sodium(DSS)- induced acute ulcerative colitis in mice.Methods Thirty BALB/C mice were randomly divided into nor- mal control group (n=10),0501 strain group (n=10) and c122 strain group (n=10).Fifty BALB/ C mice received 5% dextran sulphate sodium(DSS) for 7 days to induce ulcerative colitis.The mice were then divided to model group,negative control group(perfused with 0.9 NaCl solution ),positive control group(perfused with SASP of 20 mg/ml),DSS + 0501 strain group(perfused with 1?10~9 CFU/ml bifidobacteria 0501 strain solution and DSS + c122 strain group (perfused with 1?10~9 CFU/ml bifidobacteria c122 strain solution).All mice were sacrificed 9 days later.The colon specimens were measure by histoehemical staining with H-E.The expressions of interleukin-10 (IL-10) and its protein were detected by RT-PCR and immunohistochemistry respectively.Results The degree of colon inflam- mation in mice both in DSS+ 0501 strain and DSS+ c122 strain groups were aggravated and expressions of IL-10 mRNA and protein were reduced compared to model group.No colon inflammation was found in 0501 strain and c122 strain groups.Conclusion Some strain of bifidobaeteria may aggravate colon in- flammation in mice when mucosal harrier is destroyed.

OBJECTIVETo solve the problem of screw penetrating the joint surface easily by determining the angle of inclination and the mean longth screw plated on the posterior column.

METHODSTen specimens of adult male cadavers, aged 20 to 74 years old, averaged 54.5 years old, were collected. After removal of the bilateral femurs from the hip joints, and sawing through the sacral and pubic symphysis in the median sagittal plane, 20 semi pelvic specimens were used for this study when the osseous abnormalities were excluded. The specimens were air dried naturelly after the soft tissue attaching to the pelvis had been eliminated.

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.

To investigate the influences of sperm quality on the zygotes and embryos development, as the role of the paternal factor in early human embryogenesis is gaining more attention because of the application of techniques such as intracytoplasmic sperm injection (ICSI) for the treatment of men infertility. 136 infertility couples with men factors (Group I ) were included from May 2002 to January 2001. One hundred and seventy-two infertility couples with tube factors (Group II) served as controls. The sperm parameters, gemmates and embryos quality, implantation rate and pregnant rate in both groups were analyzed. It was found that there was no significant differences in the number of oocytes retrieved, the fertilization rate and number of embryos transferred between two groups. Sperm concentration, percentage of motile sperm and percentage of sperm with normal morphology were significantly lower in group I than in group II (P < 0.01). The proportion of good quality zygotes and good quality embryos were significantly lower in the male infertility group than in the tubal disease group (P < 0.05). Implantation rate and pregnancy rate were similar in two groups. It was concluded that spermatozoa is involved in the embryo quality, even in the early stages of development, which limited the treatment potency of IVF procedure.

Objective To explore the relationship of the ratio of plasma adrenomedullin(AM)and endothelin-1(ET-1)with serum concentration of neuron-specific enolase(NSE)in full-term neonates with hypoxic-ischemic encephalopathy(HIE).Methods Plasma concentrations of AM,ET-1 and serum NSE from 32 full-term neonates with HIE were detected by radioimmunoassay(RIA)on the 1,3 and 7 d after parturition,30 neonates in the corresponding periods in our hospital were employed as controls.The infants with HIE were divided into mild,moderate or severe group in terms of diagnostic standard of HIE.Results 1.Plasma concentrations of AM and ET-1 in newborns with mild,moderate or severe HIE were significantly higher than that of control group at 1 d after life with a decline from 3-7 d(Pa

Objective To explore the effect of exogenous adrenomedullin(ADM) on expressions of glutathion in plasma and brain tissue inneonatal rats with hypoxic-ischemia reperfusion brain damage(HIRBD) and the mechanism of action.Methods Fifty-six cases of 7 d SD rats were randomly divided into 4 groups including normal control group(without any treatment),HIRBD group(the model with hypoxia for 2 h and ischemia for 1 h),primed group(abdomen infusion of ADM at 0.5 h before making model,the other was same to the HIRBD group)and treatment group(abdomen infusion of ADM at onces after making model,the other was same to the HIRBD group).The neonatal rats in 4 groups were derived blood and brain tissue after decapitation at either 4 h or 24 h after reperfusion.The levels of gtutathion(GSH) in plasma and brain tissue were determined by using chromatometry.Results In HIRBD group,the affection areas at 24 h after reperfusion enlarged compared with those at 4 h after reperfusion.Meanwhile,the affection of punctiform degeneration or necrosis at 4 h after reperfusion transformed into the affection of lamellar or diffuse degeneration or necrosis at 24 h after reperfusion.The levels of GSH in plasma and brain tissue in HIRBD group at either 4 h or 24 h after reperfusion were significantly lower than that in normal control group(Pa0.05).Meanwhile the pathology score of brain section in primed group and treatment group were significantly lower than that in HIRBD group at either 4 h or 24 h after reperfusion(Pa0.05).Conclusion Exogenous ADM can induce the neuroprotection in HIRBD by adjusting the expression of GSH.

Obj ectiev The purpose of this study is to assess the impact of bone metastasis on survival in non-small cell lung cancer(NSCLC),Which were treated with gefitinib for more than 6 months,and to identify the prognostic factors of patients with NSCLC presenting bone metastasis .Methods We compared the overall survival(OS), progression-free survival(PFS),1-year2,-year and 3-year survival rates between two cohorts based on bone metastasis ,as well as the prognostic factors in the patients with bone metastasis .Results In total, 76 patients were included in the study ,in which there are44 patients with no bone metastasis and32 patients with bone metastasis.The cohorts were similar in OS (19.000 ±3.317 months vs.26.000 ±2.121 months,P =0.625)as well as PFS (14.000 ±1.843 months vs.16.000 ±1.411 months,P=0.328).The 1-year survival rate was 63.6%in no bone metastasis cohort,but was increased to 96.9%in the other cohort.The survival rates at 2 years(34.1%vs.56.3%,P=0.054)and 3 years(18.2%vs.18.4%,P=0.950)were similar.The univa-riate analysis showed that a worse prognosis was more likely existed in elderly patients ( aged >60 years) and with pulmonary progression ,whereby factors including gender ,pathology s,moking index ,brain metastases ,bone related events and the application of radiotherapy ,bisphosphonates might not be independently associated with the surviv -al late.Analysis of multiple variables indicated a favorable prognosis for patients with no pulmonary progression . Conclusion This retrospective study shows that bone metastasis may not shorten the survival in patients whose pulmonary lesion was controlled by gefitinib .On the contrary ,pulmonary progression may be more likely the cause of death in patients with bone metastasis .Non suggestion is given to discontinue gefitinib when the bone metastasis appears.
