Objective To investigate the optimal window level and center level settings in the diagnosis of costal cartilage fracture with 256-slice spiral CT through ROC analysis. Methods Thirty patients with suspected costal cartilage fractures underwent 256-slices chest spirals CT scaning. CT value of costal cartilage was measured by three experienced radiologists. The soft copy images of three kinds of window level and window width (-100 HU/1120 HU, 100 HU/1120 HU, 300 HU/1120 HU) were analyzed independently in PACS with dual-blind method, and the diagnosis results were taken ROC analysis with SPSS 16.0 software. The diagnostic accuracy of three physicians were evaluated and compared according to the area under the ROC curve (Az). Results A total of 8 patients of costal cartilage fractures were confirmed by CT diagnosis combined with clinical follow-up. The mean CT value of 30 patients was (98.78±32.86) HU. The area under the ROC curve with the window level and center level settings of (100 HU/1120 HU) were bigger than that of other window level and window width (P=0.045,P=0.002). Kappa identity test showed that there was a powerful conformability between the diagnostic results of three physicians. Conclusion 256-slice spiral CT is a good way for the diagnosis of costal cartilage fractures with suitable window level and center level settings.

Objective To analysis the family management of patients with serious mental illness in Gansu prov-ince, and evaluate its effectiveness to lay the foundation for the better community-based rehabilitation management and treatment for the people with serious mental illness. Method According to Treatment-management specification of severe mental illness (2012) and specification of national basic public health services (2011), the information such as home ther-apy, medicine taken, and dangerous behavior happened were collected from patients who were confirmed as serious men-tal illness in January 2015 to April 2016 in Gansu province. Result Up to April 30th, 2016, totally 70538 serious mental illnesses were identified, and about 81.10%(57195) were under management. The rate of treatment of serious mental ill-ness was 69.9%(48009/68663) in Gansu province, and Bipolar affective disorder (76.0%) was the highest (P<0.001). The rate of taking medication in patients under family-management was 42.16%(24113/57195), and the rate of taking regular medication was 24.74%(14150/57195). The rate of taking medication in Paranoiac psychosis patients (51.98%) was the highest (P<0.001), and the rate of taking regular medication in Mental disorders caused by epilepsy (31.02%) was the highest (P<0.001). Conclusion The rate of family-management, treatment, taking medication and take regular medica-tion of serious mental illness in Gansu province are all below the national average level.

Objective: To study the gene expression characteristics of steroid- and catecholamine-synthesizing enzymes in adrenal gland of spontaneously hypertensive rats (SHRs), Goto-Kakizaki (GK) rats and normal Wistar rats with the same traditional Chinese medicine syndromes. Methods: Sixteen-week-old Wistar rats, SHRs and GK rats were used. By the quantitative four diagnosis and syndrome differentiation methods and GeneChip Mouse Exon 1.0 ST Array, we observed adrenal gland gene expressions in normal Wistar rats, qi deficiency Wistar rats, SHRs with qi deficiency and qi excess, GK rats with qi deficiency and qi excess. Differentially expressed genes of steroid- and catecholamine-synthesizing enzymes and their regulatory factors were analyzed. Results: Thirty-one genes were differentially expressed among all syndromes. Hsd3b6 was down-regulated significantly 6.0-fold in GK rats with qi deficiency syndrome and qi excess syndrome, and Cyp11b2 was up-regulated 1.5 times in GK rats with qi deficiency syndrome. Por, Hsd11b2, and Nr2f6 were up-regulated in all syndromes, and Cyp2c23, Cyp4a3, Cyp4a8 and Cyp2e1 were down-regulated. However, Srd5a1 and Nr4a1 were up-regulated only in GK rats, and Lss was down-regulated only in SHRs. Th was up-regulated 1.5 times in SHRs with qi deficiency syndrome, GK rats with qi deficiency syndrome and GK rats with qi excess syndrome. Ddc was up-regulated 1.5 times in GK rats with qi excess syndrome. Dbh was up-regulated 3.0 times in GK rats with qi deficiency syndrome and qi excess syndrome. However, Comt was down-regulated 1.5 times in GK rats with qi deficiency syndrome and qi excess syndrome, and Mao was up-regulated 1.5 times in SHRs with qi deficiency syndrome and qi excess syndrome. Conclusion: Some genes associated with steroid- and catecholamine-synthesizing pathways were differentially expressed in SHRs and GK rats, and the differentially expressed genes may be related to the development of traditional Chinese medicine syndromes.

Objective To investigate the capillary blood volume (BV) changes in acute ischemic denervated hindlimb of rabbits and the value of 256-slice detector computed tomography (CT) perfusion imaging in evaluation.Methods A total of 40 healthy, adult white rabbits underwent either right hindlimb femoral artery excision combined femoral nerve denervation (combined modeling group, n = 10), simple femoral artery excision (iachemia group, n = 10), simple femoral nerve denervation (denervation group,n = 10), or simple femoral artery separation (sham-surgery group, n = 10).At 1,7, 14, 21, and 28 days following surgery, CT perfusion scanning (Philips Brilliance 256-row) was performed and CT perfusion images were processed using maximum-slope method with Function CT software on EBW workstation.The ratio of BV (rBV) in muscle tissue between right and left hindlimbs was calculated in each group.At 14 and 28 days, following sacrifice, rabbit bilateral adductor was harvested for immunohistochemical staining.The ratio of microvessei density (rMVD) in muscle tissue between right and left hindlimbs was calculated.The significance of the difference of rBV at each time point was assessed using analysis of variance of factorial design (2 ×2).Pearson correlation analysis was used to study the relationship between rBV and rMVD.Results After surgery, the 1st day rBV of combined modeling group, combined modeling group,denervation group and sham-surgery group is 0.31 ± 0.15 ( n = 6), 0.29 ± 0.12 (n = 6), 0.98 ± 0.08 ( n =6), 0.98 ± 0.07 ( n = 6) respectively.The 7th day following surgery rBV is 1.69 ± 0.45 ( n = 5 ), 1.63 ±0.43(n=6), 0.99 ±0.07(n =6), 1.00 ±0.08(n =6).The 14th day is respectively 1.58 ±0.18(n=5), 1.49 ±0.25(n =6), 0.94 ±0.08(n =6), 1.01 ±0.05(n =6).The 21th day is 1.42 ±0.41 (n=4),1.43 ±0.31(n=4), 0.94 ±0.05(n =5), 1.02 ±0.05(n =5),and the 28th day is 1.00 ±0.25(n=4),0.99 ±0.08(n=4), 0.92 ±0.09(n =5), 1.02 ±0.13(n=5).At each time point with exception of postoperative 28 days(F(A) =0.214,P>0.05), ischemia produced main effects on rBV(F(A) =274.268,30.044,65.787,18.886 ,P < 0.01 ), while simple denervation did not show main effects on each time point.Ischemia and denervation did not yield interaction effects on each time point, rMVD from each group supported above-mentioned changes.The correlation coefficient of rBV to rMVD was r = 0.862 ( P < 0.01 ).Conclusions BV in acute ischemic denervated hindlimb of rabbits shows a dynamic change, and denervation does not obviously influence this process.256-slice detector CT perfusion imaging can be used to noninvasively and semi-quantitatively evaluate the dynamic changes of capillary bed in acute ischemie denervated hindlimb of rabbits.

Abstract: Methodology of syndrome differentiation and syndrome-based treatment in rats and mice has professional characteristics and caters to the research and development of traditional Chinese medicine (TCM). In this paper, the authors introduced their systematic research in five aspects. 1) Rats and mice can be used to simulate TCM clinical practice. Diagnosis and syndrome differentiation can be done to the rats and mice, and information collected by the four diagnostic methods from the experimental animals meets the requirements of treatment based on syndrome differentiation. 2) Standardized and quantified four diagnostic methods and syndrome differentiation for rats and mice can be established, and are operational and applicable for general use. 3) There exists constitution and syndrome diversity in normal rats and mice. A spontaneous syndrome can develop in diseased rats and mice, and it can be accompanied by or even change to another syndrome, similar to that in human beings. 4) There is a complicated material base for syndromes inferred from the different gene expressions and splices in neuroendocrine-immune network. 5) Individualized treatment based on syndrome differentiation, as well as quantified evaluation and comparison of the treatment efficacy can be done in the rat and mouse models of syndromes. The established methodology and criteria for syndrome differentiation and syndrome-based treatment in rats and mice can be used in the following four research fields: 1) syndrome identification on rat or mouse models; 2) research on the basic theories of TCM, such as the research on the viscera manifestation theory, the material base of syndromes, function mechanisms of the treatment based on syndrome differentiation, and the diagnostics of TCM; 3) study in clinical subject of TCM, such as evaluation and comparison of the efficacy of treatment based on syndrome differentiation, protocol optimization of syndrome differentiation and treatment, and preventive treatment of diseases; 4) study in traditional Chinese drugs, such as the research on properties of Chinese herbal drugs, and pharmacological research on Chinese herbal medicines and formulas.
