Objective To determine the reliability of CT perfusion scans and its parameters of ?-variate curve in evaluating the acute myocardial infarction for clinical reference of diagnosis on coronary artery disease and myocardial infarction. Methods Imatron C-150 electron beam CT (EBCT) were used to scan a hydrodynamic model which could mimic a change of contrast medium by intravenous injection in vivo. Then 6 adult canines were employed in the experiment with thoracic operation, and branches of the anterior descending and circumflex of left coronary arteries (LCA) were ligated so that myocardial infarction was made out. After intravenous administration of contrast medium, the hearts were scanned with perfusion EBCT and ?-variate curves were manifested. Some heterogeneities and differentiations between the normality and the infarctions were put forward when the parameters of all these curves were analyzed and statistically processed. Two myocardial infarctions were also verified by SPECT, and all the samples stained with TTC method were compared with those on the perfusion images. The pathological study with optical microscope and electron microscope were further carried on. Results The ascending slopes of ?-variate curves were different in the perfusion quantity. The normal curve of canine myocardium showed a somewhat quick ascending pattern first, and then a gradual descending pattern successively, with the ascending time of about 10-13 s, ascending CT value of about 34-37 HU, and peak CT value of about 70-81 HU. Whereas the curve on myocardial infarction demonstrated a prolonged ascending time of about 19.9 s, diminished ascending CT value of only about 20 HU, and peak CT value of about 53.8 HU, which were significantly different from the normality (P

Objective To examine the expression levels of cyclin Dl in the patients with chronic myelogenous leukemia (CML), and evaluate the pathogenesis and clinical significance of cyclin Dl in CML Methods The real-time quantitative polymerase chain reaction (RQ-PCR) was performed to detect the expression levels of cyclin Dl in the bone marrow samples of 18 patients with CML, and 16 samples of benign hemopoietic patients. The relationship between the expression levels of cyclin Dl and the progression and prognosis of patients with CML were analyzed. Results The level of cyclin Dl was higher expressed in 18 patients with CML than the control group (P <0.001). The levels of cyclin Dl was apparently higher expressed in accelerated phase /blast crisis phase than in chronic phase (P <0.05). And the RQ-PCR method showed the tendency that a significant increase was observed in the levels of cyclin Dl from 0.1980 in control group to 1.4002 in chronic phase and 5.4540 in accelerated phase /blast crisis phase. Conclusion The cyclin Dl overexpressed in CML, the roles of cyclin Dl in CML might be an oncogene expressed. The expression level is correlated with the progression and prognosis of patients with CML.

Objective To study the effect of Jade -Screen Powder (JSP)on regulating expression of 5 microRNAs associated with helper T cells in asthmatic mouse model.Methods Forty Balb /c mice were randomly di-vided into 4 groups,1 0 mice for each group,namely normal control,asthma model,JSP treatment and Dexamethasone treatment.The mouse models of allergic inflammation on both upper and lower airways were established by ovalbumin sensitization and challenge.Interleukin(IL)-1 3 and IL -1 7 expressions were detected from lung homogenates by ELISA.Hematoxylin and eosin staining was also performed to observe the pathological changes in the lung tissue.The expressions of miR -1 46a,miR -1 46b,miR -21 0,miR -1 26 and miR -21 a were detected by quantitative real time PCR from splenocytes.Results The lower levels of IL -1 3 [(6.382 ±1 .690)μg/L]and IL -1 7 [(24.21 2 ± 1 .250)μg/L]were found in JSP treatment group compared with those in the asthma model group [(20.1 54 ±7.960)μg/L;(50.31 2 ±5.770)μg/L,rseparately],there was significant difference in IL -1 3 between JSP group and the asthma model group,as well as IL -1 7 (t =3.785,P =0.005;t =9.891 ,P =0.000).Same findings were found in Dexamethasone treated group as well [IL -1 3:(9.366 ±3.460)μg/L,IL -1 7:(29.1 32 ±4.960)μg/L;t =2.779, P =0.024;t =6.225,P =0.000].However,upregulation of miR -21 0 was observed in JSP treatment group (2.052 ± 0.871 )compared with that in the asthma model group (4.034 ±1 .379)(3.95 folds,t =2.71 8,P =0.026).Mean-time,the expression of miR -1 26 in JSP group (4.920 ±0.924)and Dexamethasone group (3.862 ±1 .51 0)in-creased compared with asthma model group (6.024 ±0.447)(2.1 5 folds,t =2.405,P =0.043,and 4.48 folds,t =-3.069,P =0.01 5).Conclusions Th2 and Th1 7 T cells participate in the pathogenesis of asthma and the asthmatic process can be inhibited by JSP.JSP may affect the helper T cells by regulating miR -21 0 and miR -1 26.

OBJECTIVETo calculate the volume embolization ratio of densely packing experimental aneurysms by three dimensional digital subtraction angiography (3D-DSA).

METHODSSix experimental crotch aneurysms were created microsurgically in the common carotid artery of white rabbits. Two weeks later, each aneurysm's volume was measured with 3D-DSA surface shaded display(SSD) and the correction of lacteprene balloon calibration method. In the same time, the aneurysms were densely packed with electric detachable coils. The volume of coils that were used in each aneurysm was calculated separately. The ratio of coils volume and aneurysm volume was the volume embolization ratio (VER).

RESULTSThe aneurysms volumes measured by 3D DSA SSD ranged from 0.037 to 0.087 ml. The VER ranged from 23.5% to 32.5% (average 27.4%).

CONCLUSIONThe minimum VER of densely packing experimental crotch aneurysms with electronic detachable coils was 23.5%.

Objective To detect the levels of procalcitonin in multiple genes autoinflammatory disease (adult Still disease,systemic juvenile idiopathic arthritis,crohn's Crohn's disease),and to explore the relationship between erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),ESR/CRP and disease or complicated infection combined disease.Methods One hundred and fifty-three patients were en-rolled,88 patients with multiple genes autoinflammatory disease,including 32 cases of adult Still disease,27 cases of systemic juvenile idiopathic arthritis,29 cases of Crohn's disease.In addition,30 cases of healthy controls,35 patients with systemic lupus erythematosus (SLE) were included into this study.Electroche-miluminescence was used to test the value of serum PCT,erythrocyte sedimentation rate was tested by blood sedimentation instrument method,the CRP level was tested by lmmunoturbidimetry,and the data was handed managed and analysised by matlab software and One-way analysis of variance (ANOVA) was used to compare the differences of PCTs between groups.Results ① In the non-infection condition,the PCT value of the autoimmune inflammatory diseases [(0.36±0.74) μg/L,95％confidence interval (CI) (0.174 9,0.550 9) μg/L)] was signifieantly higher than that of the healthy control group [(0.06±0.06) μg/L,95％CI (0.035 1,0.081 7 μg/L)],the difference was statistically significant (F=5.03,P=0.027 4),but there was no statistically significant (F=1.03,P=0.475 5) when comparing with SLE group.② The PCT level of the non-infected inflammatory enteric arthritis [(0.20±0.32),95％CI(0.042 7,0.364 3) μg/L] was different compared with the healthy group,the difference was statistically significant (F=5.77,P=0.020 4),at the same time,the difference was not statistically significant when comparing with the SLE group (F=0.22,P=0.647 6).When the PCT value in non-infected adults Still disease [(0.60±1.02) 95％CI(0.048 4,1.153 6) μg/L] compared with the healthy group,the difference was statistically significant (F=7.22,P=0.01) but the difference was not statistically different when compared with the SLE group (F=2.65,P=0.114 3).The PCT level difference was statistically significant (F=2.23,P＜0.01)when comparing infection-free juvenile idiopathic arthritis [(1.52±2.02) μg/L,95％CI(0.054 8,4.591 9) μg/L] and the healthy group,the difference was statistically significantly different (F=8.34,P=0.004 7) when compared with the PCT of the non-infected SLE group.③ In the case of autoinflammatory diseases without infection,the 95％CI of ESR/CRP ratio was between 1.121 2 and 3.589 4.In the case of co-infection,the 95％ CI of ESR/CRP ratio was between 1.502 2 and 8.718 8,so we considered autoimmune inflammatory diseases might had a high possibility of co-infection when the ESR/CRP ratio was higher than 3.5.Conclusion ① The multiple genes autoinflammatory disease group has a higher value of PCT level than healthy controls even without infection.② The mean and 95％CI range of PCT of the inflammatory bowel disease arthritis,adult Still disease and the juvenile id-iopathic arthritis is significantly higher than the healthy controls,partially higher than SLE group.In addition,the PCT level in the juvenile idiopathic arthritis is the highest.③ In clinical,to estimate whether the multiple genes autoinflammatory disease has bacterial infection,we can't just simply rely on PCT to estimate whether the multiple genes autoinflammatory disease has bacterial infection,we may consider the ratio of the ESR/CRP,when the value is higher than 3.5,we may consider patients has strong probability with infection.

OBJECTIVETo examine the impact of single nucleotide polymorphisms in obesity-related genes on risk of obesity and metabolic disorder in childhood.

METHODSA total of 3 503 Chinese children aged 6 to 18 years participated in the study, including 1 229 obese, 655 overweight and 1 619 normal weight children (diagnosed by the Chinese age- and sex- specific BMI cutoffs). Body size parameters were assessed and venipuncture blood samples were collected after a 12-hour overnight fast. Plasma glucose, insulin and serum lipid profiles were measured.Genomic DNA was isolated from peripheral blood white cells using the salt fractionation method. A total of 11 single nucleotide polymorphisms were genotyped by TaqMan allelic discrimination assays with the GeneAmp 7900 sequence detection system (Applied Biosystems, Foster City, CA, USA) (FTO rs9939609, MC4R rs17782313, GNPDA2 rs10938397, FAIM2 rs7138803, BDNF rs6265, NPC1 rs1805081, PCSK1 rs6235, KCTD15 rs29941, BAT2 rs2844479, SEC16B rs10913469 and SH2B1 rs4788102). Multiple factor analysis was performed to estimate the association between the variant and obesity-related traits. The false discovery rate (FDR) approach was used to correct for multiple comparisons.

RESULTSAfter sex, age and pubertal stage adjustment and correction for multiple testing, the rs9939609-A, rs17782313-C, rs10938397-G, and rs7138803-A alleles were associated with higher BMI (β = 0.352-0.747), fat mass percentage(β = 0.568-1.113), waist circumference (β = 0.885-1.649) and waist-to-height ratio(β = 0.005-0.010) (all P values < 0.01) in Chinese children. The rs6265-G allele increased BMI(β = 0.251, P = 0.020). The rs9939609-A, rs17782313-C, and rs10938397-G and rs6265-G alleles were also associated with risk of obesity (OR = 1.386, 95%CI:1.171-1.642; OR = 1.367, 95%CI:1.196-1.563; OR = 1.242, 95%CI:1.102-1.400; OR = 1.156, 95%CI:1.031-1.296).Rs7138803 was associated with risk of obesity only in boys (OR = 1.234, 95%CI:1.043-1.460). GNPDA2 rs10938397-G allele was associated with risk of insulin resistance(OR = 1.205, 95%CI:1.069-1.359), but there was no significance after adjusting for BMI.

CONCLUSIONThe association of FTO rs9939609-A, MC4R rs17782313-C, GNPDA2 rs10938397-G, and FAIM2 rs7138803-A with higher BMI, fat mass percentage, waist circumference, and waist-to height ratio and risk of obesity, and BDNF rs6265-G allele may increase BMI and obesity risk in Chinese children. GNPDA2 rs10938397-G may increase the risk of childhood insulin resistance depending on BMI.

Objective To discuss the clinical effects of different energy densities of enteral nutrition (EN) preparations on mechanical ventilation (MV) patients with acute severe traumatic brain injury (sTBI). Methods Sixty MV patients with acute sTBI admitted to the Department of Critical Care Medicine of Hangzhou Xiaoshan District First People's Hospital from July 2015 to December 2017 were divided into two groups according to different energy densities of nutritional preparations. Thirty patients of the control group were given nasal feeding with standard energy density EN (energy density 3.35 - 4.19 kJ/mL) and 30 patients of the observation group were given nasal feeding with relatively higher energy density (energy density 5.44 - 6.28 kJ/mL). The indexes of nutritional status between the two groups before and after treatment were compared: including prealbumin (PA), albumin (Alb), globulin (Glo), hemoglobin (Hb), 5-day and 1-week heat calorie compliance rates of reaching target calories, MV time and incidence of complications. Results There were no statistically significant differences in nutritional indicators before treatment between the two groups (all P > 0.05). The compliance rates of reaching target calories of the observation group on the 5 and 7 days after treatment were significantly higher than those in the control group [5 days: 66.67% (20/30) vs. 50.00% (15/30), 1 week: 81.33% (25/30) vs. 70.00% (21/30), both P < 0.05], and the MV time was significantly lower than that in the control group (hours: 92.48±12.04 vs. 128.88±16.29, P < 0.05); the levels of PA, Alb, Hb, Glo were significantly higher in the observation group than those in control group on the 21st day after treatment [PA (g/L): 0.28±0.11 vs. 0.15±0.04, Alb (g/L): 36.52±5.79 vs. 29.63±2.74, Hb (g/L): 92.40±9.50 vs. 81.10±8.60, Glo (g/L): 24.42±1.73 vs. 18.19±3.59, all P < 0.05]. Complications: the total incidence of abdominal distension, diarrhea and constipation of the observation group was 36.6% (11/30), while that of the control group was 66.7% (20/30), the difference between the two groups being statistically significant (P < 0.05). Conclusion High energy density enteral nutrition can improve the nutritional status of the organisms of MV patients with acute sTBI, reduce the time of MV and the incidence of complications, thus it is worthy to be widely applied clinically.
