Objective To measure the length between the bifurcation of abdominal aorta to the femoral artery puncture point in adult women.Methods 127 patients were enrolled in the study.Femoral artery puncture using of the roberts uterine catheter (RUC) for the diagnosis and treatment of obstetrics and gynecologic disease was conducted.When the RUC bending vertex code located at the bifurcation above, fingers fixed femoral artery puncture point at the mouth of the catheter's sheath and evacuate the catheter and measure the code to the fixed position.Results In this group, the length of the bifurcation of abdominal aorta to the femoral artery puncture point was 24.38-25.33 cm.There was no significant difference in the length with patient age (P>0.05), but there were statistical significances with the patients height and weight(P<0.05).Conclusion The length of adult women abdominal aortic bifurcation to the femoral artery puncture point has no significant difference with patient age.The individual height and weight are very much significant.The length estimation can be done according to the patient's height and weight for low abdominal aortic catheter,on clinic for avording X-ray irradiation or no X-ray equipment condition.

Objective To investigate the clinical value of echo-tracking(ET) technique in evaluating the carotid elasticity in patients with hyperuricemia and hyperuricemia combined with hyperlipidemia.Methods One hundred and twenty patients with hyperuricemia were divided into two group:group of hyperuricemia (group A) and group of hyperuricemia combined with hyperlipidemia (group B).Sixty normal persons were served as the control group.ET was used to measure the carotid artery elastic modulus including stiffness parameters (β),pressure-strain elastic modulus (Ep),arterial compliance (AC),augmentation index (AI) and pulse wave conducting velocity (PWVβ).Then the statistical data were analyzed to observe the changes of each parameter.Results In the comparison of three groups,elastic function index β,Ep,PWVβ and AI in group A and group B were higher than those of control group (P ＜0.05) ;however,AC was lower than that of control group (P ＜ 0.05).Compared with group A,elastic function index β,Ep,PWVβ,AI was higher in group B,while the AC was lower than that of group B (P ＜0.05).Conclusions ET may be helpful to prevent atherosclerotic changes and to provide the basis for the clinical diagonosis and treatment atherosclerotic changes.

Objective To study the prevalence,risk factors of overactive bladder (OAB) in middle-aged and senior residents in Zhengzhou China.Methods A randomized,community-based,crosssectional study was performed on 10 160 residents aged 40 or older in urban area of Zhengzhou by using a stratified system sampling approach.A questionnaire including the subjects' basic information,previous history,present history,the Chinese overactive bladder symptom score (OABSS) was filled on site.The diagnostic criteria for OAB was 'an urgency score for Question 3 of 2 or more,and an OABSS of 3 or more'.Chisquare test was used to determine the differences of prevalence between genders,age groups,BMI and people with and without diabetes mellitus (DM).A pairwise comparison was conducted between different age,BMI group by using Bonferroni method.Results A total of 10 160 residents were investigated and finally 9805 (96.5％) were qualified for final statistical analysis.The mean age was (57.9 ± 9.7) years.The overall prevalence of OAB was 2.1％ (209/9805),of which,with OABdry 1.0％,and OABwet 1.1％.Male subjects were more likely suffered from OAB than female,with 2.7％ (84/3129) versus 1.9％ (125/6676).The prevalence of OAB in both male and female increased with age.There was no significant difference in the prevalence of male and female before the age of 60 years (1.2％ versus 1.4％,P ＞ 0.05) and more common in men than in women after the age of 60 years (4.6％ versus 2.6％,P ＜ 0.05).The prevalence of the subjects with DM was significantly higher than those without DM (P ＜ 0.05).The subjects with BMIs of 30 or more were nore likely to have OAB (3.2％ versus 1.8％,P ＜ 0.05).Conclusions The prevalence of OAB increases with advancing age.The prevalence of male is higher than female after the age of 60 years.The diabetics and obese people are more likely to have OAB.

Biologically important proteins related to membrane receptors, signal transduction, regulation, transcription, and translation are usually low in abundance and identified with low probability in mass spectroscopy (MS)-based analyses. Most valuable proteomics information on them were hitherto discarded due to the application of excessively strict data filtering for accurate identification. In this study, we present a staged-probability strategy for assessing proteomic data for potential functionally important protein clues. MS-based protein identifications from the second (L2) and third (L3) layers of the cascade affinity fractionation using the Trans-Proteomic Pipeline software were classified into three probability stages as 1.00-0.95, 0.95-0.50, and 0.50-0.20 according to their distinctive identification correctness rates (i.e. 100%-95%, 95%-50%, and 50%-20%, respectively). We found large data volumes and more functionally important proteins located at the previously unacceptable lower probability stages of 0.95-0.50 and 0.50-0.20 with acceptable correctness rate. More importantly, low probability proteins in L2 were verified to exist in L3. Together with some MS spectrogram examples, comparisons of protein identifications of L2 and L3 demonstrated that the staged-probability strategy could more adequately present both quantity and quality of proteomic information, especially for researches involving biomarker discovery and novel therapeutic target screening.
