Objective To study CT and MRI value in diagnosis of osteoblastoma,in order to achive more information about the disease. Methods The clinical,CT,MRI and histological data of 12 patients with osteoblastomas. Results(1)There were 6 patients wereexamined by CT,the lesions showed mainly lytic with varying degrees of matrix mineralisation,and mild adjacent reactive sclerosis;(2)10 patients were examined by MRI(included 4 patients who have been examined by CT),the lesions presented mixed signal intensity with compart,slightly low and intermediate signal intensity on T_1-weighted images,high signal intensity on T_2-weighted images were found in 9 cases and mainly low signal intensity was found in 1 case.8 cases showed clear low signal intensity surrounding the lension borh on T_1 and T_2,2 cases showed blurry high signal in the adjacent tissue;(3) The tumors presented moderate enhancemen with low dense area inside the lesions after injection of contrast media. Conclusion Osteoblastomas have classical features on CT,while show no characteristic appearances on MRI.

Objective To evaluate the inhibitory effects of NF-κB inhibitor pyrrolidine dithiocar-bamate (PDTC) on NF-kappa B activity and the serum inflammatory mediators in hypertensive-ventricular hypertrophy-congestive heart fail?ure rats. Methods The rat model of hypertension-cardiac hypertrophy-heart failure was made from 42 male Dahl salt sen?sitive rats. Rats were randomly divided into seven groups including group A (normal diet group), group B (high salt diet group), group C (NF-κB inhibition in early stage), group D (NF-κB inhibition in hypertensive stage), group E (NF-κB inhibi?tion in cardiac hypertrophy stage of week 12) and group G (NF-κB inhibition in heart failure stage). There were six rats for each group. Rats were administrated 8%high salt diet and injected PDTC 100 mg/(kg·d)intraperitoneally according to the prescribed time. Changes of blood pressure, left ventricular end diastolic interventricular septal thickness (IVSD), left ven?tricular end diastolic posterior wall thickness (LVPWD), left ventricular end diastolic diameter (LVEDD), systolic left ventric?ular end diastolic diameter (LVESD), left ventricular ejection fraction (LVEF), heart, lung weight/ body weight ratio, NF-kappa B activity, tumor necrosis factor (TNF)-α, interleukin (IL)-6, monocyte chemotactic protein (MCP)-1 and C-reactive protein (CRP) were observed in different treatment time points of PDCT. Results Levels of NF-κB and proinflammatory cy?tokines were reduced after early administration of PDTC, and the cardiac function was also decreased. The longer the treat?ment time, the greater the protective effect on heart. PDTC can effectively control blood pressure, and block left ventricular hypertrophy and left ventricular failure in a certain extent. The effects of PDTC were limited after persistent hypertension, and myocardial hypertrophy formation accompanied by heart failure. Conclusion PDTC plays a role in prevention and treatment of hypertension, left ventricular hypertrophy and congestive heart failure in model rats. Early application of PDTC could obviously maintain the normal cardiac function in rats with heart disease.

ObjectiveTo investigate the clinical effect and possible mechanism of modified Shenling Baizhu Powder （参苓白术散） and Xiaoluo Pill （消瘰丸） in the treatment of children with adenoid hypertrophy due to spleen deficiency and phlegm accumulation. MethodsOne hundred and thirty children with adenoid hyperplasia due to spleen deficiency and phlegm accumulation were randomly divided into 65 cases each in the observation group and control group. The control group was given mometasone furoate nasal spray， one spray into each nostril， once a day， while the observation group was given modified Shenling Baizhu Powder and Xiaoluo Pill orally， one dose per day， and both groups were treated for 8 months. The pre- and after-treatment electronic nasopharyngoscope scores， specific quality of life survey scale （OSA-18） scores， total TCM symptom scores， serum cysteine leukotrienes （CysLTs）， interleukin 2 （IL-2）， tumor necrosis factor α （TNF-α）， and interleukin 10 （IL-10） levels were compared to determine the clinical efficacy after treatment. ResultsAfter treatment， the electronic nasopharyngoscope scores， OSA-18 scores， total TCM symptom scores， serum CysLTs， IL-2 and TNF-α levels significantly decreased， while IL-10 levels increased in both groups （P＜0.01）. Compared between the two groups after treatment， the electronic nasopharyngoscope score， OSA-18 score， total TCM symptom score， serum CysLTs， IL-2 and TNF-α levels were significantly lower， and the IL-10 level was higher in the observation group than in the control group （P＜0.01）. The total effective rate of the observation group was 95.38% （62/65）， superior to 81.54% （53/65） of the control group （P＜0.05）. ConclusionFor children with adenoid hypertrophy due to spleen deficiency and phlegm accumulation， modified Shenling Baizhu Powder and Xiaoluo Pill can help to improve symptoms， increase quality of life and clinical efficacy， and its mechanism may be related to reducing the inflammatory response.

Objective To analyze the effect of guizhi gancao decoction on dardiac function and serum VCAM-1 and sE-selectin levels in patients with coronary heart diseaser. Methods Fifty-eight patients with coronary heart disease were enrolled in this study from September 2014 to June 2015. According to the different treatment methods, 40 patients were treated with conventional western medicine. The observation group of 40 cases were treated with conventional western medicine and Guizhi licorice soup. The effects of cardiac function, 6-minute walking test, cardiac parameters and serum sE-Selectin and ICAM-1 levels were observed. Results Observation group of patients with cardiac ultrasound parameters LVEF (43.27 ± 5.21)%, LVEDd (59.34 ± 5.43) mm, FS (26.32 ± 1.63)%, E / A (1.23 ± 0.22) and 6 min walking distance were better than those of the control group (t=2.3628,P =0.0206;t=2.4643,P=0.0159;t=2.7831,P =0.0068;t=2.5023,P =0.0144;t=3.7571,P =0.0006). The markedly effective rate was 47.50%, which was higher than that of the control group (25.00%), and there was significant difference (χ2 = 4.3813, P= 0.0363). In the observation group, 4 patients were ineffective and the inefficiency rate was 10.00%, which was significantly lower than that of the control group (χ2 = 4.0205,P= 0.0450). The levels of TC (5.21 ± 0.82) mmol / L, TG (1.22 ± 0.32) mmol / L and LDL-C (2.44 ± 0.52) mmol / L were significantly lower in the observation group than those in the control group (t= 3.2729, P = 0.0016; t= 3.5119, P = 0.0007; t= 3.5136, P= 0.0007). While the HDL-C (1.21 ± 0.17) mmol / L index was higher than that of the control group (t = 5.4575, P = 0.0000). There was no significant difference in serum index between the two groups before treatment . After treatment, the serum sE-Selectin (75.58 ± 9.97) ng / mL and VCAM-1 (662.43 ± 65.78) ng / mL were lower than those in the control group (t = 3.4082, P = 0.0010;t = 3.3088, P = 0.0014). Conclusion Treatment of CHF patients with CRT / CRT-D pacemaker implantation in the heart after surgery can effectively improve its clinical condition, and the effect is outstanding, side effects, and CRT-D better effect.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma with highly heterogeneous clinical course. How to recognize patients with high risk is coming into the focus of the 57th American Society of Hematology (ASH) annual meeting. The International Prognostic Index (IPI) score as a classic prognostic system is challenged by variety of new prognosis systems. The tumor microenvironment plays an important role in progression of lymphoma, and its prognostic value draw much more attention. The value of PET-CT for prognosis of DLBCL has also been affirmed in this meeting.

Objective To study the serum levels of homocysteine(Hcy) and the polymorphism of C677T mutation of methylenetetrahydrofolate reductase (MTHFR) gene in pregnant women to explore their role in the pathogenesis of pre-clampsia. Methods Fifty pregnant women with preclampsia (study group) including 14 mild pre-eclampsia and 36 severe pre-eclampsia and 40 healthy ones (control group) were selected. Hey concentration was determined by fluorescence polarization immunoassay. The mutations of the 677C→T and 1298A→C of MTHFR were investigated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results The mean level of plasma Hey in the study group was higher than that of control 1(12. 00±4. 59) μmol/L vs (7. 85:1:1.51) μmol/L, P<0.05], and that of the severe pre-eclampsia group was higher E(13. 30±2. 06) μmol/L, P<0. 01]. However, no significant difference was found between the control and the mild pre-clampsia group[(8. 63±3. 94) μmol/L, P>0.05]. There was significant difference in the genotype frequencies of MTHFR 677CT, TT genotype(C/T:42.0% ;T/T:14. 0%)and the total frequency of mutant T (T: 35.0%) allele between the study and control groups (P < 0. 05). Conclusions Hyperhomocysteinemia plays an important role in the pathogenesis of pre-clampsia. The polymorphism of MTHFR C677T might be associated with the development of pre-clampsia as it affects the metabolism of Hey.
