Objective:To study the clinical benefit of propofol anesthesia with target-controlled influsion technic modulated by cerebral state index in the elderly patients with tumor. Methods:A total of 126 ASA Ⅰ or Ⅱ aged65 yrs or older patients underwent gastrectomy and rectal surgery were randomly divided into tow groups(n=63 each):group by target-controlled influsion technic modulated(groupⅠ)and group by target-controlled influsion(groupⅡ). CSI of groupⅠwas 50. Propofol of two groups was administered by TCI at a target blood concertration of 2?g/ml during induction of anesthesia and maintenance of anesthesia,sufentanil of two groups was administered by TCI at a target blood concertration of 1.5?g/ml during induction of anesthesia and of 0.3ng/ml during maintenance of anesthesia. MAP,HR,HRV and CSI of the foundation(T1),intubation(T2),five minutes after intubation(T3),chip(T4),the tumor excision(T5) and the end of surgery(T6) were recorded. And the total of propofol was recorded. Results:MAP at T3,T4 and T5 of groupⅡdecreased obviously compared to that of groupⅠ(P

Objective:To investigate the effect of pridoxamine on erectile function in diabetic rats.Methods:Male adult Sprague-Dawley rats were induced for diabetes by an intraperitoneal injection of streptozotocin,then randomly divided into DM group and DM+PM group.The rats in DM+PM group were treated with pridoxamine at a dosage of 200mg/kg through a gastric perfusion every day.Twelve weeks later the erectile function of all these rats were evaluated,and their penises tissues were harvested.The NO,NOS,and cGMP levels in corpus cavernosum were measured.Results:The diabetic rat model was successfully established.The erectile function was much better in normal control group(group C,100%) and DM+PM group(71.4%)than in DM group(46.2%)(P

Objective To the expression of cytokines assay in peripheral blood and hematoma fluid of hypertensive cerebral hemorrhage,and the hemodynamic changes in brain tissue around the hematoma by using perfusion computed tomography imaging(PCTT)and immune turbidimetric analysis and analyze its influence on prognosis.Methods Fifty-six cases of hypertensive intracerebral hemorrhage patients were inspected with conventional CT and PCTT,quantitative analysis of hematoma and the contralateral corresponding area around the cerebral blood flow(CBF),cerebral blood volume(CBV),mean transit time (MTT),comparing acute and subacute phase CBF,CBV,MTT change.Peripheral blood,hematoma fluid compiement C_3 and C_4 levels were detected.Results In 56 patients with acute phase ipsilateral CBF,CBV,MTT were(19.3 4±3.1)ml/(min·100 g),(1.4 4±0.4)ml/g,(16.5 4±3.1)s,respectively,and in eontralateral were(50.3 4±3.4)ml/(min·100 g),(2.4±1.1)ml/g,(4.8±2.6)s,the corresponding index difference between the two sides were statistically significant(P<0.05).Subaeute phase ipsilateral CBF,CBV,MTY were(29.7±2.1)ml/(min·100 g),(1.9±0.6)ml/g,(8.9±2.7)s,the in contralateral were (48.2±6.3)ml/(min·100g),(2.3±0.7)ml/g,(4.7±1.6)s,the corresponding index difference between the two sides were statistically significant(P<0.05).Subacute phase CBF,CBV,MTT compared with acute phase,the difference Wag statistically significant(P<0.05).Acute and subacute phase of complement C_3 and C_4 in peripheral blood and hematoma fluid content of the differences were statistically significant(P<0.05).Acute and subaeute phase of edema ratios were 0.9 and 0.4,the difference was statistically significant (P<0.05).Conclusions The cerebral blood flow and cerebral perfusion of the brain tissue amund hematoma after the cerebral hemorrhage are decreased.PCTI Can analyze the intracerebral hemodynamic changes of the brain tissue around hematoma after the cerebral hemorrhage,which is helpful to treat hypertensive cerebral hemorrhage and estimate its prognosis.

Objective:To observe the prevention of glutathione(GSH)against chronic liver injury in rat.Methods:The chronic liver injury model was made by intracutaneous injection of carbon tetrachloride twice a week in rats for 24 times.From the 8th week after the carbon tetrachloride injection,GSH was given by oral or peritoneal administration once a day for 60 days.The animals were sacrificed at the end of the experiment.The serum level of ALT,AST were measured.The liver tissue was studied with histopathological or immunohistochemical assay.Results:GSH markly decreased the serum level of ALT,AST and improved liver tissue inflammation and lessend the liver fibrosis in histopathology compared with the model group.In the immunohistochemical stain,the deposition of type Ⅰ collagen of liver tissue significantly decreased in GSH treatment group compared with the model group.Conclusion:GSH can protect live from injury induced by toxic material.

Objective:To obtain the clone and gene of light chain on human antibody against HBs.Methods:The phage displaying library was subjected to three rounds panning of “adherence-elution-amplification” with HBsAg coated in solid phase and help phage.The positive clone against HBsAg was characterized by ELISA assay and its P/N value was 2.415.The recombinant plasmid vectors from the positive clone was amplified by PCR with designed oligonucleotide primers of ? light chain.The ? chain PCR fragment was subcloned into plasmid pUC18 and sequenced.Results:The phage antibody against HBsAg was screened from a human immunoglouin phage displaying library.The pUC18-? recombinant plasmid was constructed and sequenced.The gene size of ? chain is 643bp including variable region and constant region.Conclusion:According to the sequenceing and ELISA assay,we suggest that ? chain is a human anti-HBs-? immunoglobuin.

OBJECTIVE To characterize the pathogenic distribution and drug resistance of nosocomial infection occurred in tumor hospital and therefore provide the information in rational administration of antibiotics to tumor patients complicated with infection.METHODS Flora cultivation and isolation were operated with the methods described by the National Clinical Laboratory Operational Regulations.Flora was identified with the VITEK-32 automatic identifier,and bacteria-susceptibility test was operated with Kirby-Bauer method.RESULTS Totally 1280 strains of pathogenic bacteria were isolated;they comprised 874 strains of G-bacteria and 416 strains of G+ bacteria.In this study,the isolation rates of Pseudomonas aeruginosa,Escherichia coli,Acinetobacter,Enterobacteriaceae and Klebsiella were 14.92%,14.92%,14.06%,13.91% and 10.47%,respectively;whereas that of Streptococcus Group D and Staphylococcus aureus were 24.06% and 7.70%,respectively.Both E.coli and S.aureus were much resistant to antimicrobial agents tested;while imipenem and vancomycin might be chosen for the G-and G+bacteria infection.CONCLUSIONS The bacterial spectrum and their drug-resistance characteristics in the tumor hospital are quite similar to that encountered in general hospitals.So the information on nosocomial infection control from the latter is of great importance in directing on and carrying out the same job in tumor hospital.

Objective:To analyze the cause of patients with hepatic failure induced by viral hepatitis to provide guidance for the clinical treatment. Methods:Retrospective analysis was adopted to study the clinical data of 115 patients died of hepatic failure induced by viral hepatitis enrolled in our department for five years.The data of each case was collected from the check of final diagnosis and the last check before death. Results:Of all 115 patients,103 cases were male,12 cases were female. with an average age of 45.7 years.There were 89 cases with chronic severe hepatitis,20 cases with cirrhosis.114 cases infected hepatitic B virus including 12 cases with superfection of HAV,HDV,HEV.Of 110 cases,24 were HBeAg positive24/ 110,21.8%),61 were HBeAb positive(61/110,55.5%). Of 85 cases,HBV DNA quantity of 68 cases was more than 1?105 copies/m(l68/85,80%),HBV DNA quantity of 17 cases was less than 1?10(517/85,20%).TBil,PTA and ALT at admission were 403.17 ?219.43,38.33 ?19.14 and 496.78 ?801.56 respectives,while those at death were 478.03 ?234.89,32.39 ? 16.54,218.04?426.58 respectively.Severe complications presented. Conclusion:In our country,hepatic failure was mainly induced by chronic severe hepatitis and cirrhosis infected with hepatitis B virus. The active replication of HBV DNA and the viral mutation could be causes of the development of disease. As the incidence rate of complications is high,preventing complication is necessary to reduce fatality rate of the patients with hepatic failure.
