Objective To evaluate the diagnostic value and technique advantage of 16-slice CT angiography(16SCTA) in aortic dissection.Methods 39 cases of aortic dissection underwent 16SCTA.The data were reconstructed by multiplanar reconstruction(MPR),curved planar reconstruction(CPR),volume rendering(VR),maximum intensity projection(MIP),virtual endoscopy(VE),and generally analyzed in combination with original axial images.Results According to DeBakey's classification,DeBakey's type Ⅰ in 5 cases,type Ⅱ in one case and type Ⅲ in 33 cases were founed in the 39 cases.16SCTA clearly showed that including the ture and false lumen(39 cases,100%),intimal flaps(39 cases,100%),intimal tear(25 cases,64.1%),and thrombus inside the false lumen(17 cases,43.6%).Conclusion 16SCTA may be as the first choice method in diagnosis of aoric dissection,and which is considered as having great value.

Objective To study the CT signs of bronchotracheal transparent foreign body and its diagnostic value.Methods The X-ray and CT findings of bronchotracheal trasparent foreign body in 46 cases were analysed comparativly.Results Among 46 cases,9 cases of trachea foreign body,13 cases of right bronchial foreign body,7 cases of left bronchial foreign body,2 cases of both sides of bronchial foreign body were showed directly by CT,and 8 cases of right bronchia foreign body,6 cases of left bronchia foreign body,1 case of both sides of bronchia foreign body showed indirectly on CT,the sensitivity was 100 percent,while the foreign body and its anatomical location could not be showed on X-ray film,but the indirect signs just like pulmonary emphysema,obstructive pulmonitis and drowned lung etc,could be showed by X-ray films in 34 cases.In another 12 cases were negative,the sensitivity was 73.9 percent.Conclusion The transparent foreign body can not be showed but indrect signs by X-ray film;While CT scan can not only shows the anatomical location of foreign body,but also the shape and size of the foreign body,it offers more information than X-ray films and has important refering value to clinicians to take out the foreign body.

[Objective]To observe the degradation process of PDLLA in the intervertebral fusion.[Method]Twenty goats were divided into 4 groups as experimental group,and their L_(3~4)intervertebal spaces were implanted with PDLLA cage containing pieces of graft bone.Animals were sacrificed at 4,8,12,16 wks and specimens were taken for observation of the degradation process and bone fusion by gross observation and electronic microscope.Another 12 goats were used as normal fusion control group.Their L_(3~4)space were grafted with bone block for fusion.[Result]The degradation rate was non-lineal.In the early stage of fusion,the main degradation and decrease of molecular weight was shown at the superficial decomposition.With the proceeding of fusion and degradation,as the kydrolyzation speeding-up,internal decomposition by self-catalyse resulted into the collapse and total disassemble of the PDLLA.The PDLLA cage maintained its shape in the early stage and its biomechanical strength decrease in late stage but was still enough to keep the structure from collapse,till the fusion was achieved in the bone implant area.[Conclusion]The velocity of degradation of PDLLA is slower than the speed of bone regeneration of bone fusion,so the PDLLA cage could provide sufficient support during the process of intervertebal fusion and is a suitable choice of degradative material for cage in the intervertebal fusion.

Objective To elucidate the regulate role of the guava leaf on the levels of IFN-? and IL-2 in the salivary juice on children patients with noroviruses diarrhea. Method 50 patients with noroviruses diarrhea was grouped randomly to group A (30 patients), which was treated with guava leaf and group B (20 patients), which was treated with Smecta, and 20 health children was randomly choiced as normal control group. The levels of IFN-? and IL-2 in the salivary juice of the three groups were determined and compared before and after the treatments. Results The levels of IFN-? and IL-2 in the group A and B before the treatments were higher than the normal control group (P

Objective To investigate the related factors for Alzheimer's disease(AD) in Han versus Uygur populations in Uygur Autonomous Region.Methods A case-control study was conducted.Firstly,people over 50 years old were involved in epidemiology inquisition in Xinjiang Uygur Autonomous Region.Then we screened for dementia by MMSE and scrutinized the person who got the score of MMSE for illiteracy(≤17),elementary school(<20),middle school and above it(< 24)by Hachinski Ischemic Score(HIS) and activity of daily living scale(ADL).Finally,AD cases were diagnosed by standard of the national institute of neurologic,communicative disorders and stroke and AD-related disorders association (NINCDS-ADRDA),and controls were selected based on age roughly.Univariate and multivariate analysis of related factors for AD in the two populations were conducted by using logistic regression mode.Results There were 109 AD cases and 218 controls in Han population and 127 AD cases and 254 controls in Uygur population.Logistic regression analysis showed that the risk for AD in Han population was increased by 3.078,1.369 and 2.794 folds respectively in women,people with high level of serum total cholesterol and people with low-density lipoprotein cholesterol as compared with men,people with normal level of serum total cholesterol and people with low-density lipoprotein cholesterol(OR =3.078,1.369 and 2.794,respectively,all P< 0.05); and the risk for AD in Uygur population was increased by 3.279,3.447,1.407 and 1.746 folds respectively in women,people with brain trauma history,and people with high level of serum triglyceride and total cholesterol as compared with men,people without brain trauma history and with normal level of serum triglyceride and total cholesterol(OR=3.279,3.447,1.407 and 1.746,all P< 0.05).Conclusions The study demonstrates that female and high total cholesterol are the risk factors for AD in both of Han and Uygur populations.High level of low-density lipoprotein cholesterol is one of the risk factors for AD in Han population,and brain trauma history and high level of serum triglyceride are risk factors for AD in Uygur population.

Objective To investigate the relationship between gastrin expression and the development of coloreetal neoplasm and cell proliferation.Methods 15 samples of normal coloreetal mucosal tissue,21 samples of coloreetal adenomas and 70 samples of colorectal cancer were selected for evaluation of the expression of gastrin and Ki67 with immunohistochemieal method.Results In normal colorectal mucosal tissues.colorectal adenomas and coloreetal cancer,the positive rates of gastrin expression were 0.28.6%and 25.7%,respectively-which were signff-ieantly hisher in coloreetal cancer and adenomas groups than in the normal colorectal mucosal tissues(P<0.05).But there was no significance between colorectal cancer and adenomas(P>0.05).The positive expression rate of Ki67 with the obove samples were 40.0%,76.2%and 82.8%-respectively,with statistical results identical with results of gastrin(P<0.05).There was significant correlation between gastrin and Ki67[P<0.05).Conclusion Gastrin and Ki67 are highly expressed in eolorectal neoplasm.Gastrin miight play an important role in the carcinogen-esis and development of colorectal neoplasm,and might promote tumor cell proliferation.
