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.

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.

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.

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 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

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 evaluate the accuracy of contrast enhanced ultrasonography (CEUS) in determining the depth of myometrial invasion in endometrial carcinoma in stage Ⅰ.Methods Seventy-six patients previously diagnosed of endometrial carcinoma by curettage of uterine underwent transabdominal sonography (TAS) and CEUS to assess myometrial invasion,among which 48 patients proved to endometrial carcinoma in stage Ⅰ after total abdominal hysterectomy and bilateral salpingo-oophorectomy were studied.The findings of TAS and CEUS to determine endometrial carcinoma IA (no myometrial involvement or invasion of the inner half of the myometrium) and IB( invasion of the outer half of the myometrium) were compared with pathology after abdominal hysterectomy.Results Twenty one tumours (43.75%,21/48) were enhanced earlier than or simultaneously as myometrium and cervix,among which 12 cases were IA stages,while 9 cases were IB stages (P<0.05);and 27 tumors (56.25%,27/48)were enhanced late than myometrium and cervix.There was no statistical difference between TAS and CEUS in detecting endometrial carcinoma in IA and IB(P>0.05).The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of TAS and CEUS in diagnosing endometrial carcinoma in IB were 61.25% vs 69.23%,77.14% vs 85.71%,50.00% vs 64.28%,72.92% vs 88.23%,72.92% vs 81.25% respectively.Conclusions CEUS is not superior to TAS in detecting deep invasion of endometrial carcinoma in stage Ⅰ.

Objective The effect of hypoxia inducible factor-1α( HIF-1α) , p-glycoprotein ( p-gp) and human papillomavir-us(HPV) infection on non-small cell lung cancer (NSCLC) and their interrelationship are still not clear .The article aimed to study the relationship between HIF-1αand P-gp, their role in the occurrence , development and multidrug resistance of NSCLC , as well as the in-terrelationship among HIF-1α, p-gp expression and HPV infection . Methods By using immunohistochemistry , the expression of HIF-1αand p-gp was detected in 60 NSCLC tissues and 20 benign lung disease tissues .PCR was employed to detect the expression of HPV16/18 DNA. Results The positive expression rate of HIF-1αand p-gp was 48.3% and 60.0% respectively in NSCLC, but there was no positive expression of HIF-1αand p-gp detected in the benign lung disease group (P<0.05).The expression of HIF-1αwas in positive corelation with p-gp in NSCLC (r=0.313, P<0.05).The detective rate of HPV DNA was 41.7% in NSCLC group and 5.0%in the benign lung disease group , and there was a significant difference between them (P<0.05).The positive expression rate of HIF-1αin HPV DNA positive group and negative group was 52.0% and 45.7% respectively, which showed no significant difference (P>0.05).The positive expression rate of p-gp in HPV DNA positive group and negative group was 64.0% and 57.1%respectively, which showed no significant difference too (P>0.05). Conclusion HIF-1αand p-gp are involved in the occurrence, development and multidrug resistance of NSCLC .HPV infection may be one of the etiological factors in the carcinogenesis of NSCLC . However , neither the HIF-1αexpression nor the p-gp expression is associated with HPV infection .
