Objective To study the effect of automobile exhaust pollution saturation of carboxyhemoglobin (COHb) in traffic policemen. Methods 169 traffic policemen working outdoors were selected as a exposure group and 112 traffic policemen working indoors as control group in a traffic policemen detachment in Tangshan. Questionnaires and health examination were conducted in two groups. The carbon monoxide levels in the exhalation were measured in 281 traffic policemen by a micro_smokerlyzer and the corresponding saturation of carboxyhemoglobin (COHb) were read. Results The higher saturation of carboxyhemoglobin were observed in exposure group (2.30%?1.49%) compared with those (1.71%?0.99%) in control group (P

Objective To explore whether the dopamine D1 and D2 receptors were involved in pathogenic mechanism of Parkinsonian mice induced by paraquat. Methods The models of Parkinson's mice were induced by oral paraquat. The levels of dopamine D1 and D2 receptor proteins and the expression of receptor mRNAs in striatum were examined by immunohistochemistry and in situ hybridization, respectively. Results Mice treated by oral paraquat (10mg?day -1 ?kg -1 ) for four months displayed marked hypoactive behavior. The levels of dopamine D1 and D2 receptor proteins in the striatum were significantly decreased by 28% and 29%, respectively (P

Objective The clinical efficacy and safety of L dopa monotherapy and concomitant L dopa therapy with dopamine agonists (bromocriptine or pergolide) of the treatment of Parkinson's disease Methods The clinical trial was performed in the multicentre,open label study L dopa group: 47 cases,L dopa plus bromocriptine group: 43 cases and L dopa plus pergolide group: 48 cases The clinical efficacy was assessed with modified Webster's scale and motor dysfunction rating scale for Parkinson's disease ( MDRSPD ),and safety data included blood hepatic and renal function tests,blood and urine routine tests,arterial blood pressure,heart rate measurements and electrocardiogram were also analyzed at the beginning and end of study The average daily dose of L dopa in levedopa group was (523 3?235 9) mg,The average daily dose of L dopa and bromocriptine were (526 7?241 3) mg and (7 3?1 5) mg in L dopa plus bromocriptine group,respectively The average daily dose of L dopa and pergolide were (558 3?192 9)mg and (0 235?0 045) mg in L dopa plus pergolide group separately Result The clinical improvement was about 74 5%both in assessment of modified Webster's scale and MDRSPD in L dopa group The clinical score was improved in 69 8% (Webster's scale) and 79 1% (MDRSPD) in L dopa plus bromocriptine group,respectively The clinical improved rates were 77 9%( Webster's scale ) and 81 3%( MDRSPD ) in L dopa plus bergolide group The incidence rates of side effects were 27 7%in L dopa group,39 5%in L dopa plus bromocriptine and 18 8%in L dopa plus pergolide groups Conclusion There was an efficacy in treatment of Parkinson's disease in either L dopa monotherapy or combination with bromocriptine or pergolide The treatment of L dopa alone was more effective in the early stage of Parkinson's disease and concomitant L dopa therapy with dopamine agonists were more effective in the advanced stage of Parkinson's disease,pergolide was not only more effective,safe and tolerable,but also fewer adverse events than Bromocriptine was in this short term trial

10 beats/min) to be with frequent monomorphic ventricular ectopic beats originating in the right outflow tract. Using activation-mapping for the earliest endocardial activation of spontaneous monomorphic ventricular ectopic beats, the site was ablated by RFCA.Results The immediate successful rate was 100% (28/28). Holter monitoring before and after ablation found monomorphic ventricular ectopic beats:15.836-32.419 beats/24 h vs 0-1.236 beats/24 h.Following-up of 6-24 months found all the 28 patients living in normal state.No complication occurred.Conclusion RFCA of frequent monomorphic ventricular ectopic beats originating in the right outflow tract is safe and effective.

Objective To study the role of ventricular responses(VR) in radiofrequency catheter ablation (RFCA) of idiopathic ventricular tachycardia(VT).Methods Thirteen patients underwent RFCA by using a combination of surface ECG,activition mapping and VR.The ablation targets were primarily selected by activition mapping and was determined by the VR in RFCA,and then,the final ablation target was determined and ablated where VR and VT had the same ECG results.Results Thirteen patients were successfully ablated.The VRs showed:the VR induced by RFCA in sinus rhythm was just the same as VT;intermittent sinus rhythm appeared between VT;two couple or couplets,or premature beats appeared intermittently in sinus rhythm,and finally sinus rhythm appeared;the VR induced by RFCA was not the same as VT.Conclusion The ablation target should be the site where the VR induced by RFCA is just the same as VT;the occurence of VR that is just the same as VT can be the predictor of successful ablation.

Objective To investigate the relationship between the variation of cerebrospinal fluid pulse pressure and that of intracranial perfusion pressure during the process of increasing intracranial pressure.Methods Fourteen dogs were installed epidurally with latex sacculus to establish models of increased intracranial pressure. The degree of intracranial pressure and volume could be altered by changing the volume of fluid in the sacculus. During the process, pressure transducers were arranged to monitor and record the systematic blood pressure and the variation of the pressure of cerebral ventricle and lumbar subarachnoid space.Results With the continual increasement of intracranial pressure, the cerebral perfusion pressure decreased, and the cerebrospinal fluid pulse pressure correspondingly increased. A positive linear relationship between the variation of intracranial pressure and that of cerebrospinal fluid pulse pressure and a negative linear relationship between the variation of cerebral perfusion pressure and that of cerebrospinal fluid pulse pressure were found.Conclusion During the experimental process of increased intracranial pressure, with the decrease of cerebral perfusion pressure , the cerebrospinal fluid pulse pressure increases. The relationship of variations between them shows a negative linear one. It seems that in the circumstances when the autoregulation of cerebral vessel is injured, the variations of cerebrospinal fluid pulse pressure may produce some useful information as to the changes of intracranial blood flow.

Objective To study the changes of low-frequency-component of intracranial pressure (ICP) fluctuation during intracranial hypertension. Methods 15 healthy mongrel dogs were used to make models of intracranial hypertension by arranging latex sacculus epidurally.The different amount of normal that was injected into latex sacculus led to fluctuation of ICP and alteration of intracranial volume. The pressures in ventricle and lumbar spinal canal were recorded continuously by baroceptor, and the changes of low-frequency-component of ICP fluctuation were studied by frequency-spectrum analysis. Results After increase of intracranial pressure and volume,pulse wave (M wave) with its frequency at 0.1～0.2 Hz showed continually. Conclusion Emerge of M wave may reflect some decrease of intracranial compliance and the beginning of volume compensation failure.

Objective To observe the effects of MPP+ on the expression of inhibin, activin and its receptor ⅡA and cell ability in PC12 cells of rats.Methods The changes of expression of activin?A, activin?B, inhibin? and receptorⅡA mRNAs were assayed by RT-PCR, the change of cell viability was detect by tyrpan blue exclusion method in cultured PC12 cells at 3 h,6 h,12 h,24 h after MPP+ was added and compared with control groups.Results The expression of activin?A, activin?B and activin receptorⅡA mRNAs in PC12 cells were down-regulated significantly after MPP+ administrated at every time point while the expression of inhibin? mRNA remained unchanged. The cell viability decreased at the points of 12 h and 24 h after MPP+ administrated.Conclusion MPP+ may cause the injury of PC12 cells by downregulating the expression of activin and its receptor.
