Objective To investigate the change of low-density lipoprotein cholesterol (LDL-C) /high-density lipoprotein cholesterol (HDL-C) ratio in newly diagnosed patients with type 2 diabetes mellitus (T2DM) and metabolic syndrome (MS), and to discuss its relationship with the clinical parameters. Methods Totally 140 newly diagnosed T2DM patients were selected for this study, and they were divided into MS group (n=73) and non-MS group (n=67) according to the presence of MS; the normal control group included 73 participants (NC group). All participants underwent an oral glucose tolerance test (OGTT) and insulin releasing test; meanwhile, the blood glucose, insulin, blood lipid and other items were measured. The LDL-C/ HDL-C ratios of each group were calculated. Clinical parameters and LDL-C/HDL-C ratios were compared among different groups, and correlation analysis was made between LDL-C/HDL-C ratios and clinical indices. Furthermore, all participants were divided into three groups according to LDL-C/HDL-C levels and the prevalence rates of MS were compared. Results The LDL-C/HDL-C ratios of MS group (3.18±0. 85) and non-MS group (2. 61±0. 93) were significantly higher than that in NC group (2. 26 ±0. 70, P

OBJECTIVE To evaluate the standard of non-invasive diagnosis of Down′s syndrome between the different PCR machines. METHODS Two kinds of PCR machines were used respectively to amplify the homologous genes-the human liver-like phosphofructokinase gene (PFKL) and the human muscle-like phosphofructokinase gene (PFKM). RESULTS The best annealing temperature of the two PCR machines were 64 ℃ and 60 ℃,and only in this reaction conditions PFKL′s and PFKM′s electrophoresis strips had the same optical density value. CONCLUSIONS This approach has proven that the conditions of amplified the PFKL and PFKM are different between the two kinds of PCR machines.

BACKGROUND: With the extensive application of small animal imaging and imaging studies, it requires the investigators to master the cross-sectional anatomy of mice, but the anatomy of mouse nasal cavity and sinuses cannot be obtained through vivisection.OBJECTIVE: To establish a highly precise serial colorful sectional image data set of mice using digital virtual human technology.METHODS: An adult male Balb/c mouse was killed for freezing embedded using modified Kawamoto's method and was then serially scanned at 5 μm of thickness by Leica CM3600XP cryostat microtome. The sectional images were photographed with a 24 million pixels Nikon D750 camera and stored as JPG files. All images were preliminarily registered by manually cropping the images based on the edge of block surface using software photoshop 7.0. Then, the image size, brightness and registration were corrected and adjusted, and the format of the images was unified as TIFF. The data set was imported to Amira 6.0 and was registered again with least square method. The quality of the data set was evaluated by three-dimensional reconstruction. RESULTS AND CONCLUSION: A total of 6034 original images with a size of 87 GB were captured. After cropping, adjusting and registration, the final size was 184 G. The mouse three-dimensional reconstruction model was satisfactory. To conclude, the data set established using the method and system mentioned above is characterized by high resolution and high-fidelity, which might facilitate the further study of the precise anatomy of mice and other fundamental experiments.

Objective To investigate whether specific cellular uptake of 99Tcm-survivin-ASODN in nude mice bearing human HCC is influenced by its cytosine content.Methods Three kinds(A1,A2,A3) of synthesized survivin ASODN with three cytosine contents(10％,20％,30％),20 bases per single-strand were prepared.They were labeled with 99Tcm by conjugating with a bifunctional chelator HYNIC,purified through Cellufine GH-25 and then encapsulated with liposome.Antisense gene imaging and the biodistribution of 99Tcm-HYNIC-survivin ASODN in nude mice bearing HCC were performed.The data were analysed by Kruskal-Wallis H test.Results At 4 h post injection,all the 3 labelled compounds showed increased uptake by tumor,liver and kidney.With increase in cytosine content,the uptake increased in kidney (％ID/g:1.50±0.06,2.80±0.09 and 3.96±0.03),and decreased in tumor (％ID/g:2.08±0.08,1.69±0.01 and 1.20±0.09).T/NT in imaging (4.49-4.93,4.12-4.21,3.35-3.85;H=12.50,P＜0.05) and in biodistribution (4.08-4.94,4.02-4.18,3.66-3.85;H=10.82,P＜0.05) were all significantly different.Conclusion ASODN with lower cytosine content shows higher uptake by HCC tumor cells and less stasis in kidneys,thus providing better quality in antisense gene imaging.

Ulcerative colitis (UC) is a chronic inflammatory disease and its involvement area in colon is influenced by a complex network of gene interactions.We analyzed the weighted gene co-expression networks in microarray dataset from colonic mucosa of patients with UC and identified one gene co-expression module that was highly associated with the progression of involved area in UC colon (Pearson coefficient=0.81,P＜0.0001).In total,523 hub genes in this module were found to be involved in immune system process after enrichment analysis in Gene Ontology.By the STRING and Cytoscape analysis,we observed that interleukin-8 (IL-8) and matrix metalloproteinase-9 (MMP-9) were centered in the network of hub genes.We then detected the expression of IL-8 and MMP-9 in mucosa from left-sided colon of patients using quantitative PCR and immunofluorescence assay respectively.Both quantitative PCR and immunofluorescence assay revealed the expression levels of IL-8 and MMP-9 were significantly different among the healthy controls,left-sided colitis group and pancolitis group (P＜0.05).IL-8 and MMP-9 were detected with an enhanced expression in pancolitis as compared with left-sided colitis and healthy controls,respectively (P＜0.05).This study demonstrates that immune system process is indispensable in the progression of disease in colon,and identifies that IL-8 and MMP-9 play potential critical roles for the progression.

Objective: To observe the therapeutic efficacy of music electric stimulation of points in treating anxiety. Methods: By adopting a design of multi-centered randomized controlled trial (RCT), a total of 270 patients with anxiety were randomized into a treatment group and a medication group. The treatment group was intervened by music electric stimulation of points, while the medication group was intervened by oral administration of doxepin. The two groups were evaluated by using Hamilton anxiety rating scale (HAMA) and Chinese revised edition of self-rating anxiety scale (SAS-CR) before and after the intervention. The therapeutic efficacies were also compared. Results: The total effective rate was 93.6% in the treatment group versus 92.3% in the medication group, and the between-group difference was statistically insignificant (P>0.05). After the treatment, the aggregate scores of HAMA and SAS-CR were significantly changed in both groups (both P<0.001), and the inter-group differences were statistically insignificant (P>0.05). Conclusion: Music electric stimulation of points can produce equivalent efficacy in treating anxiety compared to doxepin. Thus, it can be taken as a choice in the treatment of anxiety.

Acupuncture anesthesia is a technique by partially or completely replacing anesthetics with acupuncture in surgery based on the traditional acupuncture analgesia mechanism.It emerged in the 1950s,went viral in the 1970s and then gradually fell into decline.In the recent years,this technique has regained attention and further research.Acupuncture anesthesia can be classified as either pure acupuncture anesthesia or acupuncture-medication combined anesthesia.To expand the application of this technique,a patient with non-ST elevation acute coronary syndrome in urgent need of percutaneous coronary intervention (PCI) received pure acupuncture anesthesia because of an allergy to lidocaine,and the operation went successfully.This is the first time that pure acupuncture anesthesia and coronary arteriography were combined,which is of great significance in further study and development of acupuncture anesthesia.

Objective:To investigate the electrocardiographic characteristics of left and right ventricles origin of premature ventricular contractions(PVCs) during V3 transition of precordial leads, right ventricular outflow tract (RVOT) anterior septum and right coronary sinus (RCC), and RVOT middle-posterior septum and left coronary sinus (LCC).Methods:From January 2017 to September 2019, 91 patients with ventricular extrasystole of outflow tract who had V3 transition in precordial lead and had successful radiofrequency ablation in RVOT anterior septum, middle posterior septum, LCC and RCC were selected for retrospective case control study.The electrocardiography measurements of PVCs were compared between the anteroseptal RVOT group and RCC group, as well as the middle-posterior septal RVOT group and the LCC group, respectively.The measurements included the R-wave amplitude in lead Ⅰ, Ⅱ, Ⅲ and aVF, R amplitude ratio in leads Ⅲ to Ⅱ, Q-wave amplitude in lead aVL and aVR, Q amplitude ratio in leads aVL to aVR, R-wave and S-wave amplitude from leads V1 to V3, the V2S/V3R index, the transition zone index, and the V2 transition ratio.Results:Thirty-six cases originated from the anteroseptal RVOT, and 11 from the LCC.Lead I R-wave amplitude in anterior septal RVOT was higher than LCC group((0.22±0.25) mV vs.(-0.17±0.33) mV; P=0.003). R-wave amplitude in lead Ⅱ was lower than that in the LCC group((1.59±0.35) mV vs.(1.76±0.27) mV; P=0.035). R-wave amplitude in lead aVF was lower compared with the LCC group((1.53±0.35) mV vs.(1.78±0.39) mV; P=0.050). The V2S/V3R index showed a significant difference between these two groups(1.99±0.66 vs.0.76±0.38; P<0.001). The V2 transition ratio also appeared a significant difference between the two groups(0.69±0.43 vs.1.05±0.35; P=0.005). PVCs arose from the middle-posterior septal RVOT in 32 cases, and from the RCC in 12 cases.Compared with RCC group, lead Ⅰ R-wave amplitude showed lower ((0.25±0.31) mV vs.(0.57±0.12) mV; P<0.001); R amplitude ratio in leads Ⅲ to Ⅱ higher (0.89±0.14 vs.0.72±0.18; P=0.002); Q amplitude in lead aVL((0.72±0.24) mV vs.(0.51±0.16) mV; P=0.002)higher, and Q amplitude ratio in leads aVL to aVR higher in the middle-posterior septal RVOT(0.76±0.23 vs.0.50±0.21; P=0.002). Conclusion:Among the cases with lead V3 transition, PVCs originated from the anteroseptal RVOT show significantly different R wave in lead Ⅰ, Ⅱ, aVF, V2S/V3R index, and the V2 transition ratio compared with those from the LCC.The PVCs from the middle-posterior septal RVOT and the RCC have different R wave in lead Ⅰ, R amplitude ratio in leads Ⅱ and Ⅲ, Q amplitude ratio in leads aVL and aVR.Combined with its different characteristics, it can help to identify the origin of left and right ventricles.
