A kind of saliva glucose detector based on electrochemistry is designed to measure the saliva glucose of diabetes mellitus, so as to achieve non-invasive measurement for diabetes mellitus state. A Prussian blue modified glassy carbon electrode was designed as the working electrode of the three-electrode system to improve the electrode sensitivity to H2O2's electrochemical reaction in a lower voltage. A three-electrode system was employed for measuring the current generated by the oxidation-reduction reaction of glucose catalyzed by glucose oxidase. Technique of shield-driving was used to avoid the attenuation of the voltage when it was processed, so as to ensure the precision measurement. A single chip microcomputer, C8051F020, was used to control the system and provide scanning voltage for the electrode, make A/D transition and process the result. Then the outputs were displayed on liquid crystal display. This detector's operating voltage was 0.496 V. The sensitivity was 0.1 mmol/L. There was a constant of proportionality between the measuring results of this detector and the precise analysator, Lanbiao LK98B. Results of the study show that this detector has low operating voltage, high sensitivity and good function of whole system, and can meet the request of measure.

Objective The change of thyroid hormones affects male sexual function, but the underlying physiological mechanism is not yet clear.The aim of this study was to explore the association of thyroid hormones with abnormal penile neuro-electrophysiology in patients with premature ejaculation (PE).Methods This retrospective study included 52 acquired PE (APE) patients aged 35.36 ± 8.39 years and 24 healthy males aged 32.87±7.45 years.We measured the levels of thyroid hormones in all the subjects and, based on the latency time of penile sympathetic skin responses (PSSR), classified the APE patients into a normal (n=31) and an abnormal PSSR type (n=31).Results The concentration of total tetraiodothyronine (TT4) in the serum was significantly higher in the APE patients than in the normal control ([102.81±18.37] vs [92.68±11.56] nmol/L, P=0.018).The levels of serum TT4 and free tetraiodothyronine (FT4) were both markedly increased in the APE patients of the abnormal PSSR type as compared with those of the normal PSSR type ([113.28±20.89] vs [95.72±12.42] nmol/L, P<0.001 and [12.02±0.88] vs [10.81±1.63] nmol/L, P=0.003).The FT4 concentration was correlated negatively with the latency time of PSSR (r=-0.363, P=0.008) and positively with the Premature Ejaculation Diagnostic Tool (PEDT) scores (r=0.455, P=0.001).Conclusion Abnormal PSSR may be associated with elevated levels of thyroid hormones in APE patients, and regulation of thyroid hormone levels may help improve the symptoms of PE with abnormal PSSR.

Objective To explore the effect of neural cell adhesion molecule (NCAM) on adhesion,migration and morphology of mouse bone marrow-derived mesenchymal stem cells (BMSCs).Methods We isolated and cultured BMSCs from wild-type and NCAM gene knockout mice.The expression of NCAM was detected by Western blot and immunofluorescence.Wound healing and adhesion assays were used to detect cell migration and adhesion ability respectively.The morphological changes were observed and the expressings of protein β1 integrin,E-cadherin,β-catenin and N-cadherin were analysed by Western blot.Results The migration and adhesion of BMSCs were significantly reduced after NCAM gene knockout.Meanwhile,the expression of β1 integrin was lower than those in wild-type BMSCs (P<0.01).The morphology of NCAM gene knockout BMSCs changed from irregular to flattened,and expressed epithelial identification marker E-cadherin and β-catenin (P<0.05).However,the expression level of mesenchymal identification marker N-cadherin was decreased (P<0.01).Conclusions NCAM is involved in adhesion and migration of BMSCs via regulating the expression of β1 integrin.Furthermore,NCAMmay negatively regulate the mesenchymal-epithelial transitions of BMSCs.
