Objective To investigate the application value of low dose high pitch dual source CT angiography technique in diagno-sis of acute aortic dissection.Methods 21 cases of critically ill patients with suspected aortic dissection underwent total aortic angiog-raphy without using ECG by adopting the second generation dual source CT Flash Technology (pitch 3 .2 ,1 0 0 kV and 1 0 0 mAs), using a lower contrast dose (60 mL).Results All subjects accepted as low as possible radiation doses and iodine intake;at the same time,accurate information including aortic intimal tear position,intimal flap,true and false lumen,and lesions involving the range vessel signs and anatomic relationship were received,2 cases of Stanford type A,type B 1 9 cases (2 cases of aortic rupture).Average scan time 2.6 s,average effective radiation dose cm 270 mGy·cm.Conclusion High quality images by using high pitch dual source CT low dose angiography with lower contrast dose provide safe,reliable,real-time screening method for critically ill patients with aor-tic dissection caused by systemic severe compound injury.

Objective To analyze the clinical management of women with atypital squamous cells(ASC).Methods During Sep 2003 to Sep 2008,a totle of 956 women in our department were diagnosed with ASC by cytological test,they were further biopsied under the colposcope.The result of TCT,colposcopic test,biopsy and the highrisk factor were recorded and analysed;the based the biopsy were analyzed by the X~2-test;the high-risk factors and the odds Ratio(OR) were counted by SPSS10.0.Results Among the women with ASC,the rate of cervical intraepithelial neoplasia(CIN) diagnosed by the biopsy under the colposcope was 50.7% ,the rate of the high-grade lesion over CINII Was 13.3% ;if the colposcopic test were low-grade lesion,the rate of the cases which biopsys were the highgrade lesion over CINII,was 8.3% ;the high-risk factors which caused the cervical high-grade lesion were the number of sex-partners over 3,the age less than 20 yearold when the sex were made,the cervical erosion,the result of TCT with ASC-H.Conclusion Among the women with ASC,the biopsy shows multiformity;the rate of CIN and the highgrade lesion is also high;if TCT is ASC,the colposcopie test is advised;if the woman who has the high-risk factors,biopsy is advised.

ObjectiveTo investigate the effects of Tai Chi exercise on somatic function of middle-aged females.Methods60 middle-aged females had a 16-week Taichi quan exercise and changes of blood pressure, resting heart rate and vital capacity were tested.ResultsAfter Tai Chi exercise, 60 women had results of resting heart rate and blood pressure decreased, and vital capacity increased obviously (P<0.05～0.01).ConclusionTai Chi exercise maybe an effect sport manner to improve the somatic function of middle-aged females.

Tibetan Herbal medicine has its own complete theory based on five sources doctrine. And the theories of "Liuwei", "Baxing" and "Shiqi Gongxiao" formed the basic core components of the property theory of Tibetan medicine. However, books and literature of Tibetan medicine have never been systematically expounded and discussed about it specially which thus will limit the further development of Tibetan medicine theory. In this thesis, we firstly introduced three basic core components of the property theory-the "Liu Wei", "Baxing", and "Shiqi Gongxiao" and their interactions as well. At the same time, the links and similarities between the theory of Tibetan medicine and Chinese medicine theory were compared. The job of the thesis done above is to lay the foundation for further systematic reveal and development of Tibetan medicine theory.

OBJECTIVETo compare the effect of massage alone or in combination with pricking collateral blood therapy (PCBT) on mild carpal tunnel syndrome (CTS).

METHODSSixty cases with mild CTS were randomly assigned into two groups, the control group treated with massage therapy alone, and the treated group with PCBT at the six Jing points of the affected upper limb combined with massage, 30 cases in each group. The therapy was conducted in all patients for 3 courses. The therapeutic effect was observed and the differential value (D-value) of sensory conduction velocity (SCV) between the median and ulnar nerves of the fourth digit (D4) was detected before and after each course of therapy.

RESULTSAfter 3 treatment courses, excellent, therapeutic effect was shown in 26 patients and good effect in 4 of the treated group, while in the control group, the effect was excellent in 8, good in 20, and improved in 2. The effect was better in the former group than that in the latter (P<0.05). Marked difference in the D-value of SCV was shown at the end of each course in both groups (P<0.05). As compared it between the two groups, significant difference was shown at the end of the 1st and 3rd course respectively (P<0.05).

CONCLUSIONCombined treatment of massage and PCBT showed better effect on mild CTS than massage therapy alone, and the onset time may positively correlated to the frequency of applying PCBT.

To discuss the effect of environmental factors and photosynthesis on the growing of plant and the content of active components in Scutellaria baicalensis, the photosynthetic physiology index and diurnal changes of flavonoid constituent of S. Baicalensis were observed and tested in flowering and fruiting stages, and in the meantime environmental parameters were recorded. The obtained data were analyzed data by using path analysis and gray correlation analysis. The results showed that PAR and SWC were important environmental factors impacting on photosynthesis of S. baicalensis. SWC, RH and Ca were important environmental factors impacting on baicalin content. PAR, Po and Ta were important environmental factors impacting on baicalein content.

HER2, a member of epidermal growth factor receptor family proteins, is overexpressed in about 30% of human breast cancer. Increased levels of HER2 are associated with poor patient prognosis and enhanced metastasis. RNA interference (RNAi) is developed recently as a new technique which can inhibit gene expression specifically in mammalian cells. On the basis of previous study,in which two target sequences with favorable RNAi effect on HER2 were identified, a series of dual promoter siRNA-expressing vectors containing two opposing U6 and H1 promoters were constructed. After transfection of HER2-overexpressing SKBR3 breast cancer cells with the siRNA-expressing vectors, downregulation of HER2 was identified quantitatively. Subsequently, the siRNA-expressing cassettes were subcloned into lentiviral vectors by LR recombination reaction and lentivirus was prepared successfully. The results from infection of SKBR3 cells with siRNA-expressing lentivirus demonstrated that lentiviral-mediated RNAi could downregulate HER2 expression efficiently through fluorescent quantitative PCR (FQ-PCR), western blot, and FACS analysis. Furthermore, cell growth was inhibited in cell proliferation assay after treatment with siRNA lentivirus.A new tool for clarifying the function of HER2 in cancer metastasis and developing the gene therapy drug was offered.

Objective To detect the change of cerebral perfusion in pediatric patients with Leigh's syndrome (LS)by using MR perfusion technique.Methods Twelve patients with Leigh's syndrome and thirteen normal children were scanned with the sequence of flow-sensitive alternating inversion recovery exempting separate T_1 measurement (FAIREST).Their relative cerebral blood flow(rCBF)values were obtained in regions of bilateral basilar nuclei and bilateral thalami.Student t-test was used to compare them between the two groups and receiver operating characteristic(ROC)curve analysis was carried out.Results Statistical analysis revealed significant difference between two groups in the regions of bilateral basilar nuclei and right thalamus(t =3.26,P =0.002;t =2.25 ,P =0.018 ;t =2.88 ,P =0.004,respectively).The rCBF values for LS group and control group were 0.432?0.158 and 0.619?0.125 for right basilar nuclear, 0.478?0.186 and 0.621?0.123 for left basilar nuclear,0.630?0.189 and 0.833?0.160 for right thalamus,respectively.The areas under the ROC curves were 0.833 and 0.756 for the rCBF of right and left basilar nuclear,respectively.Conclusion Relative CBF maps may reveal changes of cerebral blood flow in some specific brain regions in patients with Leigh's syndrome.It can provide additional information to the clinicians in the evaluation of the disease.
