Objective To explore the diagnostic value of multiplanar reconstruction(MPR)of spiral CT in the disorders of lumbar intervertebral discs.Methods Fourty-one cases with the disorders of lumbar intervertebral discs were examined with conventional CT scans and MPR of spiral CT.CT findings of intervertebral discs at L 3/4 ,L 4/5 and L 5/S 1 were compared and observed.Results The conventional scans showed bulging and /or herniation of intervertebral discs in 35 cases,and normal in 6 cases which compression of nerveroots by intervertebral discs or osseous narrow of intervertebral discs were showed on MPR.The MPR showed compression of nerve roots,compression of dural sac or osseous narrow of intervertebral foramens in 36 cases.Conclusion MPR possesses important value in diagnosing the disorders of lumbar intervertebral discs,showing the causes of lumbar vertebral diseases and distinguishing the various diseases of lumbar vertebrae.

Proteomics is a new research area of the post-genomic era. Oncoproteomics is an important branch of it.Here we discuss the investigative outcome of thyroid oncoproteomics in recent years,such as specific tumor biomarkers and antineoplastic drug.

Objective To study the expression of iNOS and AChE during streptomycin ototoxicity and the correlation.Methods 16 guinea pigs were divided into 2 groups randomly:control group and SM group.SABC immunohistochemical staining and image quantitative analysis technique were used to observe the expression of iNOS and AChE and grey value analysis.ABR measurements were used to monitor the effects of ototoxity.Results After 10 days with drugs,the ABR threshold value of SM group increased more significantly than that of the control group(P

Stromal cell-derived factor-1(SDF-1)is an early cell growth factor which belongs to a subfamily of chemokines.The CXCR4 is SDF-1 receptor.The SDF-1 interacting with CXCR4 plays important roles in physiological and pathological processes such as hematopiesis, stem cell homing,angiogenesis and leukemic cells infiltrating.To study the expression of CXCR4 in leukemia and the relationship between CXCR4 and leukemic cells infiltration can add indicators for leukemic MIC diagnosis of immunology indexes and have great significance to take molecule targeted therapy for preventing leukemia from infiltration or relapse as well.

Subarachnoid hemorrhage ( SAH) especially aneurismal SAH is a deadly cerebrovascular disorder with very high mortality and morbidity rates, but there is still no effective treatment in clinical practice.In recent years, more and more studies have suggested that early brain injury ( EBI) may be the main factor for poor prognosis of SAH.The pathogenesis of EBI after SAH includes a series of complicated pathophysiological changes.This paper reviews the related progress of EBI after SAH from the aspects of acute cerebral ischemia, the disruption of blood brain barrier, apoptosis, autophagy, oxidative stress, inflammation, and so on.

Aim To examine the apoptosis and bFGF expression on the cochlea of guinea pig after administrated streptomycin(SM) and the antagonism of Salvia Miltiorrhiza Injection(DS) on SM ototoxity.Methods Forty guinea pigs were divided into four groups,and treated with DS and SM respectively.The apoptosis and bFGF expression were examined by TdT mediated biotin dUTP nickend labeling(TUNEL) techniques and SABC immunohistochemical staining with paraffin slide.The intensity of images were stored in a computer and analyzed by the image quantitative analysis technique.Auditory brainstem response(ABR) measurement was used to detect the ototoxicity before/after the examination.Results After 10 d treated by drugs,the ABR threshold of SM increased significantly,while the DS+SM reduced more(P

Objective: To study the correlation of blood stasis syndrome or its accompanied syndromes with Gensini score in patients with coronary heart disease (CHD) in stable condition. Methods: The syndrome types of traditional Chinese medicine (TCM) and blood stasis score in 131 CHD patients confirmed by coronary angiography were recorded. Gensini score was calculated according to the coronary pathological characteristics showed by angiography. The correlations of blood stasis syndrome and its accompanied syndromes with coronary lesion and Gensini score were analyzed. Results: Among the TCM syndrome types, blood stasis, turbid phlegm and qi deficiency were the most common syndromes, revealed in 85 patients (64.9%), 83 patients (63.4%) and 85 patients (64.9%), respectively. The coronary lesion length and Gensini score in the patients with blood stasis syndrome were much higher than those in the patients with non-blood stasis syndrome (P<0.05 or P<0.01). In the subtypes of blood stasis, the coronary lesion length and Gensini score in the patients with blood stasis accompanied by turbid phlegm syndrome were higher than those in the patients with non-blood stasis syndrome (P<0.05). And in the patients whose blood stasis syndrome score was more than 9 points, the coronary lesion length was higher than that in the patients whose blood stasis syndrome score was less than 9 points (P<0.05). Besides, with bivariate analysis, the blood stasis syndrome score showed no correlation with Gensini score (Pearson correlation coefficient was 0.104, P=0.241). Conclusion: Blood stasis syndrome is the most common TCM syndrome in CHD patients in stable condition. The blood stasis syndrome score is proportional to coronary lesion length, and reflects the severity of coronary lesion.

Objective To longitudinally analyze the unit costs and technical efficiency of the model of male circumcision in the different kinds of persons .Methods Unit costs were calculated by the person and period using longitudinal data from 3 kinds of persons ,and then technical efficiency and Malmquist indices were measured with an approach to data envelopment analysis . Results Theunit costs for changing the willingness to accept surgery changed dramatically ,decreasing from 7 166 .67 yuan(mean) to 737 .31 yuan ,while the costs for changing the ratio of the surgery increased from 666 .64 yuan (mean) to 744 .58 yuan ,and its technical efficiency was averaging between 0 .95-0 .96 .Conclusion The time series of unit costs for changing the willingness to ac-cept surgery dramatically dropped ,while changing the ratio of the surgery formed a U-shape curve with an inflection point before which unit costs dramatically dropped and another inflection point beyond which unit costs went up .These findings can inform pro-gram managers of the changing unit costs when extending or expanding the program .

Objective To investigate the effects of EGB on hepatic fibrosis and expression of Activin A in rats with fibrosis.Methods From Oct.2004 to Apr.2005,the study was conducted in 30 adult male rats in the pepartment of Gastroenterology,the people's Hospital of Wuhan University.The rats were randomized into 3 groups:control group,model group and treatment group.Except the rats in the control group,others were induced to hepatic fibrosis by intraperitoneal injection of CCl_4 twice a week for 8 weeks.Those rats in the treatment group were intragastrically administered with EGB establish model of everyday.At the end of the 8th week,all rats were sacrificed.The samples of liver was staining with HE.The expression of Activin A was determined by immunohistochemistry and RT-PCR.Results The grade of fibrosis in EGB-treated groups were lower than that in the model group(P

Objective The properties of anthocyanins in Suaeda heteroptera Kitag.were investigated.Methods Properties of the extract were determined via spectral absorption,physco-chemical analyses.Results Spectrogram results showed that the red pigment was classified to anthocyanins.The color properties of the pigment were similar to plant anthocyanins and pH changes could affect the tone of the color.The pigment was soluble in water,alcohol;slightly soluble in acetone;and insoluble in petroleum ether.Under natural light,degradation of the pigment could be accelerated.High temperature was disadvantage to the pigment stability.Redox stability was very low.Fe~(2+),Mg~(2+),Cu~(2+) and Mn~(2+) did not significant affect the tone of the color.Conclusion The pigment from Suaeda heteroptera Kitag.is water-soluble anthocyanins,and may be important nature edible pigment resource.
