Objective To investigate the changes in platele aciveation in terms of platelet fibrinogen receptor expression(PAC-1),P-selectin(CD62P),Thromboxane B2(TXB2),Endothlin(ET-1),Fibrinogen(FIB)in patients undergoing elective Sirolimus-eluting stents implantation and dual anti-platelet therapy.Methods Forty in-hospital patients with stable coronary heart disease(CHD)were enrolled in this study.Dural anti-platelet therapy with aspirin and clopidogrel were prescribed at least three days before operation to achieve sufficient inhibition of platelet activation in all patients.Peripheral artery blood samples were collected before the procedures,immediately and at 6 hours and 24 hours after the procedure,levels of PAC-1,CD62P,TXB2,ET-1 and FIB were measured.All patients were followed up for 6-12 months.Results Expression of PAC-1 and CD62P was increased significantly after stenting compared with pre-stenting and the peak appeared at 6 hours post-operation(PAC-1,P=0.001,CD62P,P=0.007,PAC1+CD62P,P=0.003).TXB2 was also increased and the peak appeared at 24 hours post operation(P=0.021).Plasma levels of ET-1 and FIB showed no difference before and after stenting.After CAG,expression of PAC-1 and CD62P,levels of TXB2,ET-1 and FIB had no significant differences compared with pre-CAG.No MACE happened in all patients.Conclusion The routine dual anti-platelet therapy cannot suppress platelet activation after elective coronary Sirolimus-eluting stents implantation.Plasma FIB and ET-1 levels were not affected by stents implantation.

Objective To describe the results of the Universal Newborn Hearing Screening (UNHS) in Beijing in 2010; and investigatethe factors related with the results. Methods The result of the UNHS investigated by 106 maternity hospitals were reported. These hospitalswere investigated with the self-made questionnaire. Results In 2010, 159888 infants (91.99%) were screened in 106 maternity hospitals inBeijing as the 1st stage UNHS. 10.32% of them failed OAE tests. 72.30% received the 2nd stage UNHS and 13.27% of them failed testsagain. The referral rate was 0.99% in the end. The screening rate of both the 1st and 2nd stage was more in the newborn with Beijing householdregistration than in those with other household registration, as well as the hospitals in urban than in rural areas. For the rate fail in the1st stage UNHS, it was more in hospitals in urban than in rural areas, with distortion product otoacoustic emission (DPOAE) than with transientevoked otoacoustic emissions (TEOAE), by the bed than in the special room, and screening only once than screening again. ConclusionThe quality of UNHS is as high as in the developed countries in the newborn with Beijing household registration. To further improvethe screening rate, it is important to focus on the newborn with other household registers and the hospitals in rural areas. The instrument, personnelqualifications, environment and operation need to be further standardized.

Objective To estimate the degree of oxidative stress and atherosclerosis praecox in patients with systemic lupus erythematosus (SLE), and emphasize on exploring AOPPs' clinical significance in premature atherosclerosis in SLE. Methods The levels of AOPPs, Hey, MDA, SOD, baPMV and CIMT were detected by ELISA and spectropholometry in 44 non-menopausal female SLE patients and 31 healthy middle-aged women respectively, and baPWV. The results were compared with AOPPs of the two groups. Then each group was stratified based on disease duration (≥5 years or <5 years) and the disease activity(active and inactive) in SLE patients. The patients' TC, TG, LDL were analyzed. T test, t' test and Pearson correla-tion were selected. Results The levels of AOPPs, Hcy, MDA in SLE patients were significantly higher than those of the healthy controls (P<0.05). The activities of SOD were lower than controls (P<0.05). The levels of AOPPs, Hcy, MDA, SOD had statistical significance between SLE patients disease duration ≥5 years or <5 years, active or inactive groups. There were two cases with CAP in patients with SLE (more than 5 years disease duration),while there wasnone in healthy controls. The levels of baPWV and CIMT in patients with SLE were higher than healthy controls (P<0.05), and had statistical significance in SLE patients disease duration more than or less than 5 years (P<0.05). The oxidative stress targets (AOPPs, Hey, MDA, SOD) had significant correlation with the level of baPWV and CIMT (P<0.01). The level of serum AOPPs had significant positive correlation with the levels of Hcy, TC, TG and LDL (P<0.01～0.05). Conclusion SLE patients have increased oxidative stress , and significantly higher prevalence of atherosclerosis than healthy controls. The disease duration and oxidative stress play important roles in the duration of atherosclerosis. AOPPs probably involves in the accelerated atherosclerosis of SLE patients. It may be a predictor for SLE complicated with atherosclerosis praecox.

Objective To investigate the effects of sensorimotor therapy on patients with knee osteoarthritis.Methods Ninety-two patients with knee osteoarthritis were divided into a treatment group and a control group by using random digits table. Both groups received conventional rehabilitation therapy, including knee isometric and isotonic contraction training, ultrashort wave diathermy as well as aerobic exercise. The treatment group was also administered with sensorimotor training, in addition to the conventional training,including the muscle strengthening and control training of quadriceps and hamstring muscle using sling exercise therapy system and on the Thera-band mattress. The visual analogue scale (VAS) for pain, manual muscle testing and knee range of motion as well as the Japanese Orthopedic Association knee function evaluation form were used to evaluate the patients. Results There was no statistic difference between the 2 groups before treatment, with regard to the evaluation parameters used in this study. After 2 months of treatment, both groups improved significantly (P ＜0.05),with the treatment group improved to a significantly greater extent (P ＜0.05). Conclusions Sensorimotor training in addition to the conventional rehabilitation treatment can further relieve the pain of patients with knee osteoarthritis joints arthritis and improve the function of patients with knee osteoarthritis.

Based on target cycling amplification and 3 ,4 ,9 ,10-perylenetetracarboxylic dianhydride derivative functionalized singal probe, an ultrasensitive electrochemiluminescence ( ECL) sensor was designed for the detection of lead ions. The hairpin substrate DNA was immobilized on the electrode through molecular self-assembly. In the presence of Pb2+and DNAzyme, the substrate was cleaved with single strand DNA fragments left on the electrode surface. Meanwhile, the target and DNAzyme was released for another cleaving circularly. As a result, the single strand DNA fragments hybridized with the assist hairpin probe H1, which leaded to the fabrication of H2 labeled with the 3 , 4 , 9 , 10-perylenetetracarboxylic dianhydride derivative functionalized hollow gold nanoparticles. With the increasing concentration of Pb2+, much more signal probe was been captured and the ECL signal of the biosensor in peroxydisulfate ( S2 O2-8 ) solution would increase. An ECL assay demonstrates that the sensor has a good linear response to Pb2+ concentration in the range of 1í10-12 mol/L-1í10-6 mol/L, with a detection limit of 1í10-12 mol/L. The fabricated sensor shows good selectivity toward Pb2+against other common metal ions.
