ObjectiveTo investigate clinical features,diagnosis and treatment of hyperlipidemic severe acute pancreatitis(HSAP) in late pregnancy. MethodsA retrospective analysis was made on 12 HSAP cases. ResultsHSAP accounting for 20%(12/60) of severe acute pancreatitis (SAP) cases, develops during the period of 28~36 weeks of pregnancy. There were 5 cases in SAP type Ⅰand 7 cases in SAP type Ⅱ. Multiple organ dysfunction syndrome (MODS) was complicated in 4 cases. HSAP is featured with severe hypertriglyceridemia (29?14)mmol/L, significant systemic inflammatory response syndrome (SIRS), large amount of lipidemic bloody ascites. All cases underwent successful. Cesarean section followed by pancreatic operation and were cured. ConclusionHSAP in late pregnancy is a specific type of SAP with fulminant clinical course leading to fetal distress. Effective management of pregnant hypertriglyceridemia helps to prevent HSAP.

Objective To investigate the clinical feature of POEMS syndrome,and raise the level of diagnosis and treat- ment.Methods The clinical data of 2 cases of POEMS syndrome were analyzed and relevant literature were reviewed. Results The clinical manifestation of 2 cases included splenohepatomegalia,splanchnocoel hydrops,endocrine func- tional disorder,nigrescence on face,protein of CSF and IgA and immunoglobulin light chain of serum increasing.The symptoms of 2 patients improved after treatment with hormone and L-Sarcolysinum.Conclusion POEMS syndrome is a rare and complicated disease that can be misdiagnosed.Follow up associated with immunology,endocrine and bone marrow aspiration examination should be carried in time on the patients suspected with POEMS syndrome,which is valu- able to the diagnosis and reducing misdiagnosis and mistreatment.

Objective To evaluate the plasma level of miR-21 in hepatocellular carcinoma (HCC) patients and its clinical diagnostic significance .Methods Case-control study was used .The plasma level of miR-21 was measured by real-time quantitative PCR.The relative expressions of miR-21 were calculated. This study included 60 cases of patients with HCC , 71 patients with liver cirrhosis ( LC ) , 52 healthy volunteers ( HV) from January to June in 2014 in Henan Province People′s Hospital.The receiver operating characteristic ( ROC) curves were analyzed to determine the sensitivity and specificity of miR-21 expression levels in HCC diagnosis. Differences between groups were assessed by the t-test.Results Plasma microRNA-21 level in the 60 patients with hepatocellular carcinoma ( 2.6 ±1.1 ) was significantly higher than in patients with chronic hepatitis (1.6 ±0.9) and healthy volunteers (1.0 ±0.6) (t=5.322,P=0.004;t =8.349, P =0.000 3, respectively ) .Plasma microRNA-21 level in the HCC patients were positively correlated with tumor size and differentiation (tdif=3.366,P=0.019;tsize =3.490,P=0.012). ROC analysis of plasma microRNA-21 yielded an AUC of 0.796 with 70.0% sensitivity and 65.3%specificity when differentiating hepatocellular carcinoma from chronic hepatitis , and an AUC of 0.934 with 89.5% sensitivity and 81.8% specificity when differentiating hepatocellular carcinoma from healthy volunteers.Conclusion The plasma level of miR-21 in HCC patients has high specificity , and maybe help to diagnose of HCC.

Purpose To observe the histopathologic changes of acquired immure deficiency syndrome (AIDS) in a Chinese Rhesus monkeys model and the pathogenesis that initiated the changes.Methods Chinese Rhesus monkeys were sacrificed after being inoculated SIVmac239 by Ⅳ(n=2)for four months.Autopsy was carried out by pathologic routine method.The lymph nodes, heart, liver, spleen, lung, kidney, digestive tract and other tissues were selected, the tissues fixed with 10% neutral formalin, and the pathologic sections were prepared by HE staining and immunohistochemical staining and special staining after paraffin imbedding.Results The main histopathological changes appeared in the immune system in different organs. The lymph nodes began to display the complex changes in a short period of time infected by the virus, including proliferation of lymphoid follicles, atrophy, or both; some lymphoid follicles of lymph nodes had few lymphocytes, with fibrous hyperplasia and immune complex (IC) deposition, displaying a burning down phenomenon.Splenomegaly and blood vessel and its endothelial cell proliferation in splenic corpuscles were noted with the immune complex deposition. Other parts of the mucosa-associated lymphoid tissue had different degrees of hyperplasia, or atrophy.Conclusion Histopathologic changes in Chinese Rhesus monkeys infected by SIVmac239 strain are very similar to human AIDS, which suggests that the model is a useful tool for the prevention and treatment study of AIDS.

ObjectiveTo explore the relationship between chronic kidney disease (CKD) and cerebral small vessel disease (SVD) in elderly patients. MethodsOne hundred and fifty-two elderly male CKD patients for experimental group and 158 elderly male for control group were recruited. Demographic data and vascular risk factors were recorded. White matter lesion (WML) was semi-quantitatively assessed by cerebral magnetic resonance imaging (MRI), and lacunar infarction (LI) was also calculated. Results(1) The prevalenees of hypertentsion and diabetes mellitus were higher in elderly CKD patients than those in control group (30. 9% vs. 19.0%, 23.7%vs. 14.6%;both P～0. 05). (2) The percentages of grade 2 and grade 3 WMLs were higher in elderly CKD patients than those in control group (34.9% vs. 24.1%, 25.7% vs. 16.5%;both P<0.05). Prevalence of LI was higher in elderly CKD patients than that in control group (45.4% vs.25.3% ,X2= 13. 70, P<0. 05). The similar Resultswere also obtained except for control subjects with hypertension and diabetes mellitus. (3) The logistic regression analysis showed that age, hypertension and low glomerular filtration rate (GFR) were closely associated with SVD in elderly CKD patients. ConclusionsHypertention and diabetes mellitus are risk factors for CKD in elderly patients. SVD is associated with CKD, and age, hypertension and low GFR may be risk factors for SVD in elderly CKD patients.
