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 level of expression of RAR?/RXR?mRNA in skin lesions of patients with psoriasis vulgaris.Methods The skin biopsies were collected fro mskin lesions in 20cases of psoriasis vulgaris and 10normal controls.Expression o f RAR?/RXR?mRNA was detected by RT -PCR.Results Expression levels of RXR?mRNA were 0.19760?0.0933in epiderm ides from psoriatic lesions,which were markedly lower than those in normal controls(0.5867?0.0132)(P0.05).Conclusion The results indicate that decreased expression of RXR?mRNA might be related to the pathogen esis of psoriasis.

Objective To study level of the expression of RAR? mRNA in the skin lesions of patients with psoriasis vulgaris. Methods The biopsies were taken from skin lesions in 20 patients with psoriasis vulgaris and the skin of 10 normal controls, and levels of RAR? mRNA were investigated with RT-PCR. Results The level of RAR?mRNA was significanlly lower in the epidermis of patients with psoriasis vulgaris than that in the control(P

Objective:To study the value and advantage of color Doppler and cervical multi-slice spiral CT (MSCT) in the diagnosis of cervical lymphadenopathy.Methods:A total of 130 patients with cervical lymphadenopathy diagnosed and treated in the Chenzhou First People′s Hospital from January 2019 to December 2020 were selected and received color Doppler ultrasound examination and MSCT examination. The results of pathological examination were used as the gold standard to compare the efficacy of the two methods in the differential diagnosis of benign and malignant cervical lymphadenopathy.Results:Ultrasound examination of malignant lymph nodes showed irregular boundaries, uneven internal hypoecho, and abundant blood flow signals in lymph nodes; ultrasound examination of benign lymph nodes showed uniform fine dot echo, uniform growth of endothelial medulla, clear and smooth boundary, no blood flow signal or scattered dot blood flow signal. The MSCT images of malignant lymph node showed irregular shape, blurred edge, obvious and uneven enhancement and higher rate of calcification. The aspect ratio of lymph nodes in benign lymph node was significantly higher than that in malignant lymph node (2.14 ± 0.48 vs. 1.92 ± 0.43), and the maximum blood flow velocity (V max), resistance index (RI) and blood flow (BF) in systolic period were significantly lower than those in lymph node [(21.38 ± 3.61) cm/s vs. (23.17 ± 2.55) cm/s, 0.62 ± 0.14 vs. 0.71 ± 0.17, (48.82 ± 13.51) ml/(min·100 g) vs. (65.61 ± 14.64) ml/(min·100 g)], there were statistical differences ( P<0.05). The most common blood flow types was lymphatic hilum type in benign lymph node, the proportion was 51.79% (29/56), while the most common type in malignant lymph node was marginal type and central type, the proportion was 44.59% (33/74) and 25.68% (19/74). The sensitivity, specificity, accuracy and Kappa value of ultrasound combined with MSCT in diagnosis were 92.86%, 95.95%, 94.62% and 0.890. Conclusions:Both color Doppler ultrasonography and MSCT can differentiate the benign and malignant of cervical lymph node lesions with better parameters such as lymph node imaging characteristics and blood flow distribution pattern, but the combined diagnosis has higher sensitivity, specificity and accuracy.

Objective To explore the effect of extended care with WeChat group combined with Omaha system on cancer-related fatigue in patients with lung cancer. Methods 80 patients with lung cancer who were admitted to our hospital from February 2016 to January 2017 were randomly assigned to the observation group and the control group. The observation group was treated with a 3-week extended care of WeChat group combined with Omaha system. The control group received usual care. Cancer-related fatigue score, anxiety and depression scale score were compared between the two groups. Results The score of cancer-related fatigue, anxiety and depression scale in observation group were significantly lower than control group after intervention (P＜0. 05). Conclusion Using the WeChat group combined with the Omaha system for care can help to relieve cancer-related fatigue, eliminate adverse emotions and establish confidence in continuous treatment in patients with lung cancer, which has a good prospect of application.

Objective:To analyze the relationship between stress hyperglycemia (SHG) and the prognosis of acute myocardial infarction (AMI) without diabetes mellitus (DM).Methods:Using a retrospective cohort study method, 396 AMI patients without DM or impaired glucose tolerance (IGT) and admitted glycated hemoglobin A 1c (HbA 1c)≤6.0% from January 2018 to December 2020 in Xuanwu Hospital, Capital Medical University were selected. Among them, 238 patients did not have SHG at admission (group A), 85 patients had SHG at admission but their blood glucose level did not reach the diagnostic criteria for DM (group B), and 73 patients had SHG at admission and their blood glucose level reached the diagnostic criteria for DM (group C). The baseline data and the incidence of main adverse cardiovascular and cerebrovascular events (MACCE) were recorded. Multivariate Cox regression was used to analyze the independent risk factors of MACCE after discharge in AMI patients without DM. Results:The incidence of MACCE after discharge in group B and group C was significantly higher than that in group A: 29.4% (25/85) and 35.6% (26/73) vs. 18.5% (44/238), the incidence in group C was significantly higher than that in group B, and there was statistical difference ( P<0.05). Multivariate Cox regression analysis result showed that SHG on admission was an independent risk factor for MACCE after discharge in AMI patients without DM ( P<0.05), and LVEF on admission was an independent protective factor for MACCE after discharge in AMI patients without DM ( P<0.01). Conclusions:SHG on admission is the independent risk factor of MACCE in AMI patient without DM. Early detection, assessment and proper intervention measures based on clinical reality should be advocated for the AMI patients with SHG to further improve the prognosis.
