Aim To investigate whether rosuvastatin induced reduction of atherosclerotic plaque was related to the expression of Sialyltransferase ( ST6 Gal-Ⅰ) in ApoE-/ - mice. Methods Six-weeks old ApoE-/ -mice fed with high fat were divided randomly into three groups: baseline group ( n=12 ) , control group ( n=12 ) and rosuvastatin group ( n =12 ) . Sixteen weeks later, control group was sacrificed. Serum and aortic intima were saved. Control group and rosuvastatin group were fed for seven weeks continually. Concentra-tions of serum lipids(TC, TG, LDL and HDL) were analyzed. Sections from the aortic root were examined by Hematoxylin-Eosin( HE) staining. The size of ath-erosclerotic lesion in each section was evaluated. Ex-pression of ST6 Gal-Ⅰ in aortic intima was detected by immunohistochemistry. Results Plasma TG and LDL-C, plaque areas and intimal thickness of control group were significant higher than those of baseline group ( P<0. 05 ) . Those results indicated that the AS model was successfully constructed. After seven weeks, the plaque areas and concentrations of serum lipids of rosu-vastatin group were obviously smaller than those of con-trol group(P<0. 05). The expression of ST6Gal-Ⅰin aortic root was decreased in control group compared to the baseline, and which was increased in control group compared to the rosuvastatin group. Conclusion Ro-suvastatin could inhibit the progression of atherosclero-sis, which might be related to the expression of ST6Gal-Ⅰ in aortic root.

Objective To investigate the correlation between cytochrome P450(CYP) 2C19 gene polymorphism with major adverse cardiovascular events(MACE) after PCI in the patients with coronary heart disease(CHD).Methods A total of 233 patients with CHD undergoing PCI in the cardiology department of our hospital from January 2014 to January 2015 were selected.All patients were given the standardized dual anti-platelet therapy of aspirin and clopidogrel.The occurrence situation of MACE within 1 year(unstable angina pectoris,cardiac death,in-stent restenosis,non-fatal myocardial infarction) was obtained by follow up.All patients were divided into the MACE group and non-MACE group.The PCR solubility curve was adopted to detect the CYP2C19 gene polymorphism.Results Among 233 cases of CHD,37 cases (15.88％) developed cardiovascular events and 196 cases (84.12 ％) did not develop vascular events;the age,sex,hypertension and diabetes mellitus had no statistical differences between the two groups(P＞0.05).The frequency of CYP2C19 * 1 in the included cases was 68.45％,which of CYP2C19 * 2 was 28.33％ and which of CYP2C19 * 3 was 3.22％.The extensive-metabolism,intermediate metabolism and slow metabolism types in the cardiovascular events group accounted for 5.41 ％,64.86 ％ and 29.73 ％ respectively,while which in the non event group were 59.69 ％,29.08％ and 11.22％ respectively,the CYP2C19 genotype distribution had statistically significant difference between the two groups(P＜0.05).The multivariate Logistic regression analysis showed that CYP2C19 intermediate metabolism type [OR 2.562,95％CI(2.825,7.350),P=0.021 0],slow metabolism type [OR 5.139,95％CI(1.289,5.232),P＜0.01],hypertension [OR 2.480,95 ％CI(1.079,5.698),P=0.032 4],smoking[OR 4.802,95％CI(1.082,18.371),P=0.029 0] were the independent risk factors for the occurrence of cardiovascular events in the patients with CHD.Conclusion CYP2C19 * 2 and CYP2C19 * 3 gene polymorphism are the independent risk factors for MACE occurrence after PCI in the patients with CHD.

Objective To study the relativity between pathology and CT diagnosis and CT classified types of the golioma of the brain.Methods Seventy cases of golioma confirmed by CT diagnosis and pathology by way of non-contrast CT scanning and enhanced scans were analysed in comparison the results of the pathology and CT appearances.Results (1)The accuracy rate of CT diagnosis was 85.7%;(2)having pointed out the CT classified types of the golioma of the brain a acording of CT appearances comibined with shape.Type Ⅰ was(low-tensity,non-enhancement types)16 cases,which can be only seen in Ⅰ and Ⅱ grade of astrocytoma oligodendroglioma,and the latter was often characterized by bending stripe-like calcification or cluster dot-like calcification,both of which occupy 33% of the total (3/9).Type Ⅱ was (ring-like enhanced patterns)13 cases,which often appeared in Ⅱ?Ⅲ?Ⅳ grade astrocytoma,charactenied by parietal-node which took up 53.8%(7/13).The pathology changes were mainly caused by the internal neceosis and a few by cystic changes.Type Ⅲ(nodular or mass-like enhancement) in 31 cases revealed by various types of goliomsas,which were typical CT appearances of medulloblastoma and ependymoma.Type Ⅳ(mixed types)in 10 cases had showed the CT appearances of malignant goliomas.(3)The results indicate that no or slight edema and mass effect as well as intensification were mainly seen in Ⅰ and Ⅱ grade astrocytomas,Ⅲ and Ⅳ grade astrocytomas were classified as the less serious and the serious both of which had distinctive differences.(4)Analyse the CT appearances of brain golioma in terms of tumor cytology had provided the pathology evidences for CT classified patterns.Conclusion CT appearances and CT classified patterns can reflect some pathologie characteristics and provide an important reference for astrocytoma pathology grading.

Medical therapy,education and scientific research are three functions of a hospital,in which education is one of the core tasks.The author thinks that we should strengthen the cultivation of the teachers;raise the level of the managements;increase the teaching input and reinforce the reform of education and scientific research so as to drive and improve the development of the hospital.

Objective To investigate the roles and significances of MMP-2 and MMP-9 in diffuse proliferative lupus nephritis by repeated renal biopsy.Methods Seventeen patients diagnosed by renal biopsy as WHO typeⅣlupus nephritis were analyzed by immunohistochemistry staining for MMP-2 and MMP-9. Double staining for MMP-2 and MT1-MMP,MMP-9 and CD68 were also performed.Patients had repeated renal biopsy after followed up for 2.5 years.The relationship between expressions of gelatinases and pathological activity index and clinical data were studied.Results MMP-2 immunoreactivity was detected in normal controls and was increased in diffuse proliferative lupus nephritis.MMP-9 staining,which was almost negative in normal giomeruli,was increased much more significantly in diffuse proliferative lupus nephritis. The immunoreactivity of MMP-2 and MMP-9 was positive in MT1-MMP staining and CD68-positive macrophages, respectively.The expression of MMP-2 and MMP-9 was reduced by 70% and 62% in 10 patients whose clinical condition was partially alleviated,while the expressions in 7 patients whose clinical condition was not alleviated,were only reduced by 27% and 32%.The staining for MMP-2 and MMP-9 were correlated with activity index of lupus nephritis and proteinuria.Conclusion Up-regulation of gelatinases expression in diffuse proliferate lupus nephritis is correlated to activity index of the disease.

0.05).Conclusions The expression of myostatin gene mRNA is increased in myotonic dystrophy.Up-regulated expression of myostatin in skeletal muscle might be associated with the mechanism of myotonic dystrophy.

Objective To study the relationship of HHV-8 K15 allelotypes in cutaneous and esophageal squamous cell carcinoma(SCC) tissue with tumorigenesis. MethodsSequence specific primernested PCR was performed to detect HHV-8 K15 gene and to determine its allelotype in paraffin-embedded tissue specimens from 40 patients with cutaneous SCC and 40 patients with esophageal SCC. Chi-square test was used for statistical analysis. ResultsHHV-8 K15 P allele was detected in 9(22.5％) of the cutaneous SCC specimens and 8(20％) of the esophageal SCC specimens. There was no significant difference in the detection rate of HHV-8 between cutaneous SCC and esophageal SCC specimens (P ＞ 0.05). HHV-8 K15 M allele was undetected in this study. ConclusionsSCC tissues appear to harbor only HHV-8 K15 P allele, and HHV-8 may play a part in the initiation and progression of SCC.
