Objective To explore the effects of ursodeoxycholic acid (UDCA) on the fluidity of rat visceral sac and placental glutathione (GSH) concentration in rats with intrahepatic cholestasis. Methods Sixty rats were randomly divided into 3 groups (20 in each). Refined vegetable oil 2.5 ml/(kg?d) was given to the control group since the 13 days of pregnancy. The ICP treatment and non treatment group received either progesterone 75 mg/(kg?d) or 17? ethynylestradiol 1.25 mg/ (kg?d) from the 13th to 17th day, respectively. From the 17th day, the control and non treatment group were fed with 0.9% nitrachloride solution 5 mg/(kg?d) and the treatment group with UDCA 50 mg/(kg?d). All rats were sacrificed on the 21st day. The visceral yolk sac cell membrane and GSH concentration were measured Results The concentration of GSH in the ICP non treatment group (1.12?0.02 mmol/g protein) was significantly lower than that of the treatmentgroup (1.38?0.03 mmol/g protein) and the control group (1.56?0.07 mmol/g protein) ( P 0.05). The fetal death rate in treatment group (9.55%) and control group (1.97%) was significantly lower than that of the non treatment group (20.47%) ( P

The effects of TSCP and TSCC on aggregation and adhesion of blood platelets were measured by turbidimetric method and salzman method respectively. TSCP and TSCC strongly increase mouse and rat platelet aggregation and platelet adhesion. These effects are important for blood coagulation. cAMP and TXB2 levels in plasma and platelet were determind by RIA TSCP significantly increased the TXB2 level in plasma and platelet. This effect may be the main mechanism of increasing platelet aggregation by TSCP.

Objective To analyze the factors related to the disqualification of urine routine and stool routine, and to formulate corresponding solutions. Methods In April 2014 to April 2017 our collected 600 cases of hospitalized patients, urine and stool samples for routine detection, made clear that cause unqualified samples related factors, and develop effective solution strategy. Results 600 cases in the selected routine urine, excrement and urine routine test specimens, the unqualified samples of total 110 cases, fraction defective is 18.33%, 490 qualified samples, percent of pass is 81.67%, the difference was statistically significant (P<0.05).There are a number of factors that cause the sample to fail, such as the contamination of the sample, the length of storage, the operation and the preparation. Conclusion In the process of actual diagnosis of disease, clinical result in urine, feces routine test specimen unqualified often appear, the reason is to a great extent, and the related nursing staff in urine and stool samples of patients before the lack of relevant guidance and so on, and nursing staff after the complete collection of specimens does not usually in accordance with the relevant standard of serious check, to avoid the sample inspection is unqualified, hospitals need to develop scientific inspection process, nurses in practice need to strict adherence to the process, and through intensive training, promote nursing staff awareness test, can to improve the qualification rate of sample test provide strong guarantee.

Objective This study was to evaluate the protective effect of pulmonary perfusion with cold modified low- potassium dextran (LPD) solution on lung function after cardiopulmonary bypass in combined aortic and mitral valve replacement. Method Twenty-four consecutive adult patients with combined aortic and mitral valve disease were divided into a control group ( n =14) and a perfused group ( n = 10). Cold modified LPD solution was infused to the main pulmonary artery in the protective group. PaO_2/FiO_2 were monitored at six different time points; preoperation, 0 hour, 1 hours, 2 hours, 6 hours and 12 hours after the termination of CPB. Concentrations of interleukin-6 and interleukin-10 in plasma were measured at four different time points; preoperation, 0 hour, 6 hours, and 12 hours after the termination of CPB. Result PaO_2/FiO_2 in the perfused group were increased more than that in the control group. The IL-6 and IL-10 increased in both groups after operations( P <0. 05). Patients of the perfused group showed significantly reduced IL-6 expression, compared with the control group ( P <0. 001), but the rising extents of IL-10 in the perfused group were higher than that in the control group ( P <0.001). Conclusion Pulmonary artery perfusion with cold modified LPD solution during cardiopulmonary bypass relieved lung injury in combined aortic and mitral valve replacement.

Objective To investigate the role of activities of sympathetic nerve in the pathogenesis of shoulder-hand syndrome (SHS) by analyzing the hand sympathetic skin response (SSR) at the acute stage of SHS after stroke. Methods 50 stroke patients with SHS at the acute stage were assigned as SHS group, another 50 stroke patients without SHS as control group (N-SHS group) and 50 health volunteers as health group. Every patient was subjected to the detection of bilateral hand SSR. Results The detection rates of SSR in the SHS group and N-SHS group were significantly lower than that in the Health group (P<0.01). In comparison within the SHS group, the amplitude of SSR on the affected hand was apparently higher than on the healthy hand (P < 0.05), but there was no significant difference in the SSR latencies in both hands ( P > 0 . 05 ) . In comparison with the health group , bilateral SSR latencies of the SHS group were longer than those of the health group (P<0.05) and bilateral SSR amplitudes were all lower than those of the health group (P<0.01). Conclusions The bilateral hand sympathetic skin responses could change at the acute stage of SHS after stroke, with possible presentations of central inhibition of sympathetic activity. The abnormality of SSR may be an early warning indicator in patients with hemiplegia after stroke complicated with SHS.
