Objective To investigate the distribution of TCM Syndromes of Parkinson's disease(PD).Methods The 125 PD patients were graded according to Hoehn-Yahr(H&Y) criteria for assessment.The assigned TCM physician investigated TCM syndromes of these patients with the structured questionnaire which was based on literature and experience of experts.Results Of 125 cases,96 ones(76.8%) presented a single syndrome,and 29 ones(23.2%) presented complex syndrome.The positive rate of main syndrome was in an order of deficiency of both the Spleen and Kidney(22.4%),yin deficiency of the Liver and Kidney(18.4%),yang deficiency of the Spleen and Kidney(16%),qi deficiency of both qi and yin(15.2%),phlegm-heat stirring up the wind(12.8%),qi deficiency with blood stasis(4.8%),deficiency of both yin and yang(4%),damp abundance due to the Spleen deficiency(3.2%),endoretention of damp heat(1.6%),stagnation of the Liver qi with deficiency of the Spleen and Liver fire flaring(0.8%).There existed a significant difference in the distribution of TCM syndromes in H&Y 1.0~1.5 and H&Y 2.0~3.0(P

Objective To determine the relationship between maternal negative major life events during the first trimester and incidence of congenital heart diseases(CHD) in their offspring.Methods The 4-2-1 medical information was referred and screen CHD children who were confirmed by Municipal hospitals over.A 1:2 case-control study was carried out with face-to-face structured interviews and telephone interviews to investigate parents of 116 children with CHD and 232 healthy matched children,including the parents′ demographic variables(such as whether the working environment exposure to toxic and hazardous substances 1 year before pregnancy,et al),mother′s experience of previous adverse pregnancy,duration of pregnancy condition(such as maternal negative major life events during the first trimester,the history of catching a cold or fever during the first trimester.The possible risk factors were analyzed by simple factors Logistic regression methods.Then,diagnosing the colinearity among these suspicious risk factors,and rejecting it if necessary.Finally,multiple factors conditional Logistic stepwise regression was used to filter once more.Results The results revealed that maternal negative major life events and taking medicine during the first trimester,mother′s experience of previous adverse pregnancy were related to the occurrence of CHD in the offspring.Moreover,maternal negative major life events during the first trimester play the most important role(OR=1.810).Conclusions Strengthening mothers′ mental health and controlling or reducing maternal negative major life events during the first trimester may be effective in reducing the risk of CHD.

The activity of eNOS was singificantly depressed by a high concentration of glucose in a concentration-and time-dependent manners after incubation of HUVECs with different concentrations of glucose and with high glucose plus insulin for different times.The physiological concentration of insulin can partially reverse the inhibitions of the activity and expression of eNOS induced by high concentration of glucose.

Objective To observe the clinical features of abdominal aortic aneurysm(AAA)in the elderly. Methods Seventy-eight elderly cases with AAA were studied retrospectively,the effect of age and AAA size on the growth of AAA were analyzed. Results Risk factors such as smoking,hypertension,hypercholesteremia and artherosclerosis were found in most patients. Aneurysm in other side was found in 25.6%of the patients.Rupture occurred in patients with a larger in size or rapidly developing AAA.The average AAA diameter inerease was 0.1 4 cm/year and it was similar for each age grade.When the AAA diameter was wider than 5 cm,it developed faster.and the growth velocity increased to 0.46 cm/year. Conclusions Age is not a risk factor that affects the development of AAA.If the AAA diameter is≥5 cm,the AAA develops quickly,then active interventions are recommended.

Objective To propose a method & Implementation for automatic blood ingredient separating and transferring.Methods Whole blood could be layered after centrifugal processing,and the color of the layers appeared different certainly.So color sensors could be used to receive different color signals of ingredient blood to control the process of separating whole blood and transfer different blood ingredients to different blood bags.When plasma was extruded out of the whole blood,resistance-strain pressure sensor was used to get the weight,and the air was cleaned out through extrusion movement.Air cleaning automatic control was realized through examining the intensity of pressure in the blood bag by photoconductive resistance.When the process of separating blood finished completely,the glue pipes could be heated automatically.The device adopted main-subsidiary configuration,the master was mostly in charge of separating and transferring blood ingredients of whole blood and the assistor was used to extrude out the air remains in the plasma bag and get the weight of the plasma.Results The assistor was made actually by using a PC as a virtual master to conduct experiments debugging and improve the assistor,and then the precision of electronic weighing reached 0.5g while the air in blood bag was almost cleaned absolutely.A communication protocol was developed and the serial communication between the master and the assistor were realized by VC6.0.Conclusion This method and device can automatically separate and transfer different blood components fast and efficiently,thus meeting the automation needs of the blood station.

Objective:To explore the effect of electroacupuncture on the expression of N-methyl-D-aspartic acid (NMDA) in the spine and the activity of α 2 adrenergic receptors in rats with stress urinary incontinence (SUI). Methods:In all, 48 adult female rats were randomly divided into a sham operation group, a model group and an acupuncture group. The sham operation group received sham vaginal distention. Both the model and acupuncture groups had SUI induced using endovaginal balloon dilatation. The former group then had no further intervention, while the latter was given acupuncture on the sanyinjiao point for one week. Urodynamic testing and leak point pressure (LPP) determination were then conducted with all three groups, as well as urethral sphincter electromyography. The expression of NMDA in the L 6-S 1 spinal segments using the polymerase chain reaction and α 2 adrenergic receptor activity was analyzed using western blotting. Results:No significant differences in the urodynamic variables were observed among the three groups. However, compared with the sham operation group, a significant decrease in the average LPP and the frequency and amplitude of the external urethral sphincter electromyography was observed in the model group. Moreover, compared with the model group, the acupuncture group showed significantly increased average LPP and higher electromyographic frequency and amplitude. The average mRNA and protein expression of NMDA in the spine were also significantly higher in the acupuncture group, as was the average α 2 receptor activity. Conclusions:Vaginal distention is an effective method of establishing urinary incontinence in rats. Electroacupuncture can not only improve the ability to store urine, it also increases urination, which may be related to the up-regulation of the expression of NMDA and α 2 adrenergic receptors.

Objective To study the primary volume of bone cement and the method of perfusion and the clinical effect of percutaneous vertebroplasty for bone metastatic tumors. Methods Percutaneous vertebroplasty was performed in 218 vertebral bodies of total 150 patients,including 92 males and 58 females with age of 26-85,averaging 56.8 y. 218 vertebral bodies included 73 dorsal vertebra and 138 lumber vertebra and 7 sacral vertebra. Operations were taken under the DSA monitoring. The approach route was selected according to the morphology of the vertebrae,damage extent and puncture site. Results Operation was successful in all 218 vertebrae of total 150 patients with a ratio of 100%. The primary volume of bone cement needed to fill dorsal vertebra was 2-5 ml,average 3.5 ml; that for lumber vertebra was 3-8 ml,average 5.5 ml; and that for sacral vertebra was 4-7,average 5.5 ml. 134 patients showed total pain relief (89.3%); 15 patients had partial remission (10%) and 1 failure (0.7%). The cement extravasated to intervertebral disk in 12 patients,to scleromeninx capsula externa in 10,to para-vertebra plexus venosus in 3 and to paravertebra soft tissue in 4. The incidence of leakage of bone cement was 13.3%,but no complications occurred during and after the operation. Concolusion Percutaneous vertebroplasty provides obvious pain relief effect for vertebral metastasis,worthy to be recommended widely in clinical application.
