Objective To investigate the expression of IL-10 and IL-6 in tissue and plasma of subtypes lymphoma and its significance. Methods Immunohistochemical technique and enzyme-linked immunosorbent assay (ELISA) were used to assess the expression of IL-10 and IL-6 in 97 cases paraffin tissue and plasma samples from different subtypes of lymphoma.Results Expression of IL-10 and IL-6 was positive in all lymphoma tissue samples, but there is no significant difference among different subtypes lymphoma (x2 =0.815, x2 =0.542, P ＞ 0.05). Tumor samples were found positive IL-10 and IL-6 expression in macrophages and vascular endothelial cells by immunohistochemistry respectively. Expression of IL-10 and IL-6 in plasma of lymphoma were higher than that in control respectively [(232.57±191.59) pg/ml vs (59.12±68.35) pg/ml,(80.70±89.68) pg/ml vs (45.68±33.66) pg/ml],with significant difference (t =6.968,t =2.896,P ＜0.05).IL-10 and IL-6 plasma levels increased with enhanced expression in lymphoma (x2 =0.815,x2 =0.542,P ＜ 0.05).Which was found to be correlated with each other (rs =0.394,P ＜ 0.05). Conclusion The expression of IL-10 and IL-6 had been found at various degrees in tissues and plasma of lymphoma.IL-10 and IL-6 in plasma of lymphoma were higher than that in controls. These results showed that IL-10 and IL-6 may cooperate in vivo with lymphoma cell proliferation and infiltrate. IL-6 and IL-10 maybe served as useful indicators for diagnosis of lymphoma.

Results Compared with B group, the concentration of VCAM-1, ICAM-1, hs-CRP and area of plaque, the thickness of endomembrane, tunica media in C, D and E groups were lower significantly, the thickness of fibrous cap was thicker significantly (P

BACKGROUND: Nano-hydroxyapatite has been widely used as reconstructive and prosthetic material for osseous tissue, owing to its excellent biocompatibility and bioactivity. But, its brittleness is one of the most serious obstacles for its wider applications as load-bearing implants. Therefore, hydroxyapatite/chitosan composites have been widely studied as bone substitute, due to their excellent biocompatibUity and suitable mechanical properties.OBJECTIVE: To review various preparation methods of hydroxya patite/chitosan composites and the development trend in this field.METHODS: Articles were searched in Medline Database (1995-01/2009-03), VIP Database (1995-01/2009-03) and "qinghuatongfang" Database (1995-01/2009-03) with the keywords of "nano-hydroxyapatite, chitosan, preparation, development trend".RESULTS AND CONCLUSION: Total 2 034 related articles were collected, including 1 634 in Chinese and 670 in English. Following excluding earilier published, duplicate, and similar studies, we brought into 37 sub-standard literatures. Hydroxyapatite/chitosan composite in nanometer size, with similar structure as natural bone, has better biological function compared with corresponding micrometer composite. Simultaneously, optimized material composition, structure and technology will obtain more suitable bone substitute in mechanical property compared with natural bone. This paper reviews preparation methods at home and abroad in recent years, with the rapid development of biological materials, hydroxyapatite compositematerials have been wisely used in bone tissue repair and replacement surgery, but its poor mechanical properties limits its clinical application.

Objective To investigate the relationship of blood pressure circadian rhythm with myocardial hypertrophy and the changes of autonomic nerve function in patients with essential hypertension (EH). Methods Eighty-two female patients with essential hypertension (EH) underwent 24-hours ambulatory blood pressure monitorings (ABPM), dynamic electrocardiogram (Holter) and echocardiography examination. Patients were classified into non-dipping group (n=40) and dipping group (n=42) according to the result of ABPM. Left ventricular mass index (LVMI), heart rate variability (HRV) in time domain (including SDNN, SDANN, rMSSD, PNN50) and heart rate turbulence (HRT) parameters (including turbulence onset [TO] and turbulence slope [TS]) were measured. Results Compared with those in dipping group, patients in non-dipping group have higher incidence of LVH (19.0% vs 52.5%, P<0.01), greater mean LVMI (112.39±12.79 g/m2 vs 121.98±13.35 g/m2, P<0.01), decreased PNN50 and rMSSD. TS value was decreased while TO was increased in non-dipping group compared with those in dipping group (both P <0.01); patients with LVH showed decreased TS and increased TO, compared with those without LVH. Conclusion In female patients with EH, non-dipping blood pressure circadian is associated with higher incidence of LVH. The HRV and HRT were more remarkably blunted in non-dipping patients, as well as those with LVH.

Background The present study investigated the prognostic value of medical comorbidities at admission for 30-day in-hospital mortality in patients with acute myocardial infarction (AMI). Methods A total of 5161 patients with AMI were admitted in Chinese PLA General Hospital between January 1,1993 and December 31,2007. Medical comorbidities including hypertension, diabetes mellitus, previous myocardial infarction, valvular heart disease, chronic obstructive pulmonary disease (COPD), renal insufficiency, previous stroke, atrial fibrillation and anemia, were identified at admission. The patients were divided into 4 groups based on the number of medical comorbidities at admission (0, 1, 2, and ≥ 3). Cox regression analysis was used to calculate relative risk (RR) and 95% confidence intervals (CI), with adjustment for age, sex, heart failure and percutaneous coronary intervention (PCI). Results The mean age of the studied population was 63.9 ± 13.6 years, and 80.1% of the patients were male. In 74.6% of the patients at least one comorbidity were identified. Hypertension (50.7%), diabetes mellitus (24.0%) and previous myocardial infarction (12%) were the leading common comorbidities at admission. The 30-day in-hospital mortality in patients with 0, 1, 2, and ≥ 3 comorbidities at admission (7.2%) was 4.9%, 7.2%, 11.1%, and 20.3%, respectively. The presence of 2 or more comorbidities was associated with higher 30-day in-hospital mortality compared with patients without comorbidity (RR: 1.41, 95% CI: 1.13-1.77, P = 0.003, and RR: 1.95, 95% CI: 1.59-2.39, P = 0.000, respectively).Conclusions Medical comorbidities were frequently found in patients with AMI. AMI patients with more comorbidities had a higher 30-day in-hospital mortality might be predictive of early poor outcome in patients with AMI.

Objective:To study the detection value of platelet activation indexes and platelet parameters in patients with hepatitis B-induced cirrhosis.Methods:40 patients with hepatitis B-induced cirrhosis in our hospital from November 2015 to August 2016 were selected as the observation group.40 healthy subjects went through physical examination during the same period were chosen as the control group.The platelet activation indexes and platelet parameters of subjects with same age in two groups were detected and compared.The detection results of the two items in patients with different stages of hepatitis B-induced cirrhosis were compared,too.Results:The PLT of observation group was lower than that of control group,while the other platelet parameters and platelet activation indexes were all higher than those of control group.The detection results of two items in patients with different stages of hepatitis B-induced cirrhosis were with significant differences,all P＜0.05.Conclusion:The platelet activation indexes and platelet parameters in patients with hepatitis B-induced cirrhosis are obviously abnormally expressed.There are significant differences among the detection results in patients with different stages.Therefore,surveillance of those indexes in patients with hepatitis B-induced cirrhosis should be strengthened.

Objective Toinvestigate the changes of liver and kidney function and morphology of the renal artery of the metabolic syndrome (MS) rats.Methods The rats were respectively fed with ordinary or high-fructose diet for 10 weeks,and then took the blood and anatomical observation,to explore the changes of liver and kidney function and morphology of the renal artery of the rats.Results The serum levels of ALT,AST,UA,BUN,CR in the control group and MS group were gradually increased with the feeding time.But those in MS rats were significantly increased than the control rats.MS rats showed dysfunction of liver and kidney,which similar to the clinical MS cases.Compared with the control group,the renal artery of MS rats had the same pathological changes as MS cases,presented with intima uneven thickening and structural disorder,medial smooth muscle cells hyperplasia to intimal,the internal elastic membrane with different degrees of damage and fracture,the film elastic fibers thickening and structural disorder,smooth muscle cell proliferation apparently,medial obvious thickening.Conclusion MS rats have mild dysfunction of liver and kidney and abnormal changes in intima and tunica media of renal artery.

Aim To study the effect of leuprorelin acetate microspheres (LE ms) on endometriosis in rats, and compare the efficacy of material drug (LE), domestic and imported LE ms (enanton). Methods Endometriosis was induced by endometrial implant in rats. Then the animals were treated with LE (20 ?g?kg -1 ?d -1 ? 28 d ,sc), enanton(20 ?g?kg -1 ?d -1 ,sc)and domestic LE ms ( 2,20,200 ?g?kg -1 ?d -1 ,sc). Results Implants in control group continued to grow, while those in groups treated with drugs shrinked significantly, and domestic LE ms could produce dose dependent inhibitory effect on the growth of endometrial implant in rats. Conclusion The domestic LE ms at the single dose of 20 ?g?kg -1 ?d -1 has the same effectiveness as enanton and routine injection with the same does of LE for 28 days.

Objective To investigate the factors implicated in the outcomes of patients with invasive pulmonary aspergillosis (IPA).Methods During a 5-year period,65 patients with IPA met the criteria set by the European Organization for Research and Treatment of Cancer/Mycoses Study Group (EORTC/MSG)in 2008 were retrospectively evaluated. The initial CT findings of eligible patients were reviewed by two senior radiologists who specialized in chest radiology.Patients were divided into the survivor (n =43 ) and non-survivor (n =22) groups according to their survival as long as 3 months after the diagnosis of IPA was made.An initial univariate analysis was used to screen variables that were related to prognosis,followed by a multivariate logistic regression analysis to examine these variables. Results Of the 65 IPA patients analyzed,23 (35％) had a proven diagnosis and 42 (65％) were probable ones.The univariate analysis showed that the rates of extra-pulmonary infection,uncontrolled underlying diseases and invasive mechanical ventilation were significantly different between the 3-month survival group and the non-survival group ( P ＜0.05,respectively),whereas chest CT findings,including air-space consolidation/massive consolidation,macronodules,infarct-like macronodules,halo signs, ground-glass opacities,small nodules,hypodense signs,cavities,crescent signs,small-airway findings,bronchial wall thickening/bronchiectasis,pleural effusion and hydro-pericardium, were not significantly different between the two groups (P ＞ O.05,respectively).Logistic regression analysis revealed that an uncontrolled underlying disease was the only independent predictor of 3-month mortality in patients with IPA (P =0.001,OR:O.024,95 ％ CI:O.003 ～0.223,B =- 3.714,SE =1.129,Wald =10.821 ). Conclusions An uncontrolled co-morbidity was the only independent predictor of mortality within 3 months in patients with IPA.The initial CT findings did not confer any informatioin of implication in predicting the outcomes of IPA patients.
