Objective The reseach of hepatic vein (HV) and inferior vein cavity(IVC) obstruction recanalized with catheter needle were evaluated. Methods 16 cases of BCS diagnosed with angiography in recent 5 years were all undergone interventional treatment. Five with HV web occlusion principally and 9 with IVC complete occlusion were treated with introducing a catheter needle to penetrate the block through jugular vein or femoral vein. Stenosis or needle track was dilated with balloon. Stent was planted to IVC in 10 cases. Results All cases were successful in technic including a segmental obstrution of IVC and with a lower IVC atresia. Venography demonstrated the patency of blood flow. HV pressure of 5 cases was reduced 1.85kPa, and IVC pressure of 11 cases was reduced 1.21kPa on an average.Conclusions The use of catheter needle technique increases the successful rate in BCS treatment.

0.05).Conclusion The increase in the amount of nm23H1 protein expression can play an important role in restraining metastasis of squamous cell lung carcinoma.The heredity instability(MSI and LOH) of nm23H1 gene may not be implicated in expression of the gene and pathogenesis and progression of squamous cell lung carcinoma.

Objective To study the therapeutic effect and significance of Naloxane on the brain function in patients with acute organ phosphorus pesticide poisoning. Methods 106 patients with acute organ phosphorus pesti-cide poisoning were randomly allocated to two groups according to the hospitalized date, the NX group(n=54) and the normal group(n=52). The two groups received the same basic treatment and the dynamic monitor about the changes of the β-EP and MDA levels in each groups, and the NX group was given additional treatment with 0.8 mg Naloxone-intravenous injection every 20 minutes till consciousness recovering or symptoms improved. Results The time of recovering consciousness was (16.71±3.17)h in NX group and (20.84±3.25)h in control group. β-EP and MDA were higher than normal before treatment in all patients (P<0.01), and were significantly reduced after treatment in NX group (P<0.05), the control group had mild change after treatment. Conclusion Relating to the inhibition of oxygen free radicals, Naloxone can reduce time of recovering consciousness and can protect the injured brain of the patients with acute organ phosphorus pesticide poisoning.

OBJECTIVE To know more clearly about the situation of Hepatitis B virus markers in clinical medical workers and take further interventional strategies to protect high risk medical workers.METHODS Hepatitis B virus markers in doctors,nurses and medical checkers who have contacted with patients′ blood,body fluid,or other occupational hazard situation,were detected by of ELISA.RESULTS Among the 587 medical workers detected,311 were with deficiency of active immunity(52.98%),196 were HBV infectors(33.39%).CONCLUSIONS Medical workers are in high risk groups of HBV infection.Medical institutions should attend to their self-protection and encourage them to take HBV vaccine to prevent iatrogenic transmission.

OBJECTIVE:To study the effects of atropine on cardiac autonomic nervous system.METHODS:Using the computerized analysis system developed by our laboratory,the characteristic parameters of heart period signal(HPS)in volunteers were examined before and 1 hour after administrating atropine(0.04mg iv).RESULTS:Atropine could decrease the mean heart period,standard deviation of heart period,high frequency components and total power of HPS spectra,and increase heart rate,relative power of ultra-low frequency components significantly.CONCLUSION:(1)Atropine can decrease standard deviation of heart period or heart rate,which means decreasing irregularity of heart rate.It is the basic reasons why high frequency components of HPS spectra increases,and parasympathetic nervous activity decreases,(2)Atropine can decrease the tonus of parasympathetic nerves,increase the tonus of sympathetic nerves relatively,and decrease the tonus of autonomic nervous system that reveals the decrease of the total power of HPS significantly.

OBJECTIVE:To study the effects of Betoloc(metoprolol)on autonomic nervous system in the heart METHODS:Using the computerized analysis system developed by our laboratory,the characteristic parameters of heart period signal(HPS)from volunteers were examined before and 3 hours after administrating Betoloc(50mg,po ) RESULTS:Betoloc could increase the mean heart period,standard deviation of heart period,high frequency components and total power of HPS'spectra,and decrease heart rate,low frequency components significantly CONCLUSION:(1)Betoloc can increase standard deviation of heart period or heart rate,which means increasing irregularity of heart rate It is the basic reason of increasing high frequency components of HPS'spectra and is also the basic reason of increasing cholinergic nervous activity;(2)Betoloc can decrease tension of sympathetic nerves,increase tension of parasympathetic nerves,and increase tension of autonomic nervous system in the heart

During the process of neurology teaching,the theory of “3-stage health intervention”was introduced,the basic skills of health management were cultivated in the whole clinical practice,which made the content of neurology education more effective and promoted the students' diathesis to be more comprehensive so as to cultivate the talents to accommodate the development of sociaty.

Objective To investigate the clinical effect and the prospect of Infliximab in treatment of intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD) patients.Methods Clinical features,inflammatory markers and coronary changes were observed in 2 cases of IVIG-resistant KD patients hospitalized in Peking University First Hospital,who were treated effectively by Infliximab.Relevant researches on the mechanism and progress of the Infliximab treatment for IVIG-resistant KD in the last 10 years were reviewed at the same time.Results Two KD patients hospitalized in Peking University First Hospital had been treated with 2 g/kg IVIG for 2 times and followed by methylprednisolone treatment.However,fever and other clinical manifestations occurred again after 2 days and 6 days when temperature returned normal.They both defervesced and all the symptoms were improved after 1 dose of Infliximab (5 mg/kg) by laboratory examinations.Four published literatures of the basic research and 9 retrospective or prospective clinical researches of Infliximab treatment of KD showed that Infliximab alleviated the inflammatory level in the KD patients significantly.Complete remission was up to 72.73％-92.11％.Those KD patients defervesced within 12 h,with dramatic improvement of symptoms and signs.Arthralgia also disappeared in the patients with arthritis.Only 1 case was complicated with hepatitis in the acute phase and cholecystitis in recovery time.A phase 3 randomised,double-blinded,placebo-controlled trial had been done to assess the addition of Infliximab to the standard therapy.Conclusions Infliximab is a feasible choice for IVIG-resistant KD patients.Efficacy and safety of Infliximab for KD treatment have been proved in the literature.However,Infliximab for KD treatment has not been indicated in the drug instruction,so the informed consent from the guardians and Ethics Committee is needed.

Objective:To evaluate influence of electroacupuncture combined point massage on aptients with cartid ar- tery arteriosclerosiss.Methods:A total of 106 patients with carotid atherosclerosis were randomly divided into rou- tine group (n=54,received health education based on routine therapy)and electroacupuncture+ massage group (n=52,received additional electroacupuncture and point massage based on routine group).Both groups were treated for two courses,20 times/course, 1 time/d.Carotid intima-media thickness (IMT)and thickness of carotid plaques were measured and compared between two groups before and after treatment.Results:There were no sig- nificant difference in thickness of carotid plaques and IMT between two groups before treatment,P>0.05 all. Compared with before treatment,after treatment,there were significant reductions in thickness of carotid plaques [left:(0.104±0.103)mm vs.(0.044±0.031)mm,right:(0.111±0.093)mm vs.(0.055±0.046)mm]in elec- troacupuncture + massage group,and they were significantly thinner than those of routine group [left:(0.190± 0.175)mm,right:(0.223±0.183)mm],P<0.01 all;significant reductions in carotid IMT [left:(0.096±0.021) mm vs.(0.086±0.019)mm,right:(0.091±0.019)mm vs.(0.087±0.018)]in electroacupuncture + massage group,and they were significantly thinner than those of routine group [left:(0.105±0.016)mm,right:(0.103± 0.020)mm],P<0.05 or <0.01.Conclusion:Electroacupuncture combined point massage can effectively reduce thickness of carotid plaques and carotid intima-media thickness.
