ObjectiveTo evaluate the impact of compliance with antihypertensive therapy in pailents with essential hypertension on risk for their first-ever cerebral infarction.MethotisQuestionnaire survey and auxiliary examinations were conducted in 114 patients with essential hypertension hospitalized for acute cerebral infaretion at the First Hospihal Affiliated to Harbin Medical University during December 2006 to December 2007,as well as in another 114 patients with essential hypertensive without history of cerebral infarction as controls during the sanle period.Univariate and multivariate 10gistic regression analyses were performed to study the relationship between first-ever cerebral infarction and compliance with antihypertensive agents and other relevant factors.ResultsAntihypertensive agents compliance,course of hypertension,and history of smoking and alcohol drinking could significantly affect their first occurrence of cerebral infarction in patients with essential hypertension(P＜0.05),with odds ratios(OR)of 0.429(95%C10.186-0.993) and 2.142(95% CI 1.052-4.364)for good and poor compliance with antihypertensive agents,respectively,as compared to those without antihypertensive treatmenL Mild drinking was a protective factor for cerebral infarction with an OR of 0.494(95%CI 0.252-0.968).kngth of hypertension with 10-19-years and more than or equal to 20 years.as compared to those with le88 than five years of hypertension,was also a risk factor for it,with an OR of 2.118(95% CI 1.075-4.174).ConclusionsCompliance of essential hypertensive patients with antihypertensive therapy was an important factor that affect their contracting first-ever cerebral infarction.Good compliance could obviously refrain them from it.Patients with poor-compliance or without treatment prone to contract cerebral infarction more easily than those with good compliance.It is necessary to improve compliance with antihypertensive agents in patients with essential hypertension as soon as possible.as well as quitting smoking and limiting alcohol drinking for prevention and control for their first-ever cerebral infarction.

Objective To explore the incidence and significance of intra-and extraosseous edema accompanying benign tumors and tumor like diseases.Methods Imaging studies including MR,CT and plain radiograph were retrospectively reviewed in 245 cases of benign osseous tumors and tumor like diseases proved by pathology(borderline tumor,cases associated with pathological fractures,cases with lesions of skull were excluded from the study).The incidence of bone marrow and soft tissue edema were defined on T2WI with fat suppression on MRI in all the cases.x2 test was performed for the incidence rate of edema in the benign tumors and tumor like diseases.The pre-operative diagnoses were reviewed,and the influence of edema to the differential diagnosis between the benign and malignant was analyzed.Results The total incidence of bone marrow and soft tissue edema associated with benign tumors and tumor like diseases was 37.1％ (91/245),which included Langerhans cell histiocytosis 85.2％ (23/27),osteoblastoma85.0％ (17/20),osteoid osteoma93.6％ (29/31),ehondroblastoma 87.0％ (20/23).There was no statistically significant difference of edema incidence among the above-mentioned four diseases.(x2=6.35,P＞ 0.05).Both cases of endosteal capillary hemangioma had edema around.No edema was found around the lesions of other kinds of diseases.41 of 91 cases (45.1％) with edema were misdiagnosed as malignant tumor by MRI pre-operatively.Conclusion The marrow and soft tissue edema is a common sign in the benign bone tumor and tumor-like diseases,and it is frequently seen in Langerhans cell histiocytosis,osteoblastoma,osteoid osteoma,chondroblastoma.

OBJECTIVETo explore the effect of combined therapy of shenmai and compound danshen injection (SM-DS) on myocardial reperfusion injury after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI).

METHODSThirty-eight AMI patients who received PCI were randomly divided into two groups, the 19 patients in the treated group were treated with SM-DS before and after PCI. Serum levels of malondialdehyde (MDA), superoxide dismutase (SOD), interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-alpha) in patients' venous blood were measured at different time-points, and the integrated left ventricular ejection isometric index (Tei) was determined by echocardiogram.

RESULTSAs compared with before operation in the treated group, MDA was higher and SOD was lower at 2 hrs, 24 hrs after operation (P < 0.05); IL-6 and TNF-alpha were significantly lower at 24 hrs, 48 hrs and 1 week (P < 0.05, P < 0.01) and the Tei began to be improved at 24 hrs (P < 0.05) and significantly improved at 1 week after operation (P < 0.01). While in the control group, MDA was higher and SOD was obviously lower at 2 hrs and 24 hrs (P < 0.01); lowering of IL-6 and TNF-alpha appeared at 1 week (P < 0.05) and improving of Tei index revealed 1 week after operation respectively (P < 0.05). Comparison between the two groups showed significant difference in levels of MDA and SOD at 2 hrs and 24 hrs (P < 0.01); significant difference in levels of IL-6, TNF-alpha at 24 hrs, 48 hrs and 1 week; and in Tei index at 24 hrs and 1 week after operation (P <0.05).

CONCLUSIONSM-DS could reduce the myocardial reperfusion injury in patients with AMI after PCI.

Spleen kidney Yang deficiency (SKYD) diarrhea is a common syndrome in tranditional Chinese medicine (TCM). Until now, there is not an ideal SKYD diarrhea rat model for the research. In this study, we compared single factor way (method I, injecting hydrocortisone and gavaging Sennae Folium) with compound factors way(method II, gavaging adenine, improper diet, exhaustion, and gavaging Sennae Folium) on establishing SKYD diarrhea rat model. After modelling, diarrhea index, D-xylose excretory rate, NOS/cGMP signal transduction system, organ index and histopathology examination were used to evaluate the two ways. The results showed that, compared with health group, all the assessment criterias of method I and method II had significant differences (P < 0.01, 0.05). In addition, the index such as diarrhea index, NOS/cGMP signal transduction system, organ index (kidney, testis and thymus) and histopathology examination had significant differences (P < 0.01, 0.05) between method I and method II. In conclusion, the compound factors modelling method better conforms to the symptom of diarrhoea model caused by SKYD. This new modelling method provides a basis for studying on TCM astringents warming and tonifying the spleen and kidney, relieving diarrhea.

OBJECTIVETo study the expressions of FXR, PPARa and Bile acid metabolism related genes in intrahepatic cholestasis of pregnant rats.

METHODS60 clean SD pregnant rats were selected and divided randomly into three groups. Since the 13th day of pregnancy rats in control group were injected subcutaneously with refined vegetable oil 2.0 mg/kg/d Rats in no-treated group were injected subcutaneously with the 17-a-ethynylestradiol (EE) 1.25 mg/kg/d until the 17th day. Those rat ih treated group were injected subcutaneously with the 17-a-ethynylestradiol (EE) 1.25 mg/kg/d until the 17th day and then were treated with fenofibrate for another four days until the 21th day. All rats were killed at the 21th day and livers were collected for study. The levels of serum TBA were examined by ELISA. The mRNA expressions of PPARa, FXR, CYP7A1, CYP27A1 and CYP8B1 were examined by real-time PCR. (1)

RESULTSThe levels of TBA were significantly higher in no-treated group (68.7+/-4.2)mumol/L and treated group (69.5+/-3.8)mumol/L compared with that of control group (26.6+/-2.3)mumol/L at the 17th day (P value is less than 0.05) and no difference found between treated and no-treated groups (P value is more than 0.05). The levels of TBA were higher in no-treated group (69.4+/-3.7)mumol/L and treated group (48.5+/-4.8)mumol/L as compared to control group (27.1+/-3.2)mumol/L at the 21th day (P value is less than 0.05). The lever of TBA was significantly lower in Treated group compared with No-treated group (P value is less than 0.05). (2) The mRNA expressions of CYP7A1, FXR, CYP27A1 and CYP8B1 increased in No-treated group (1.55+/-0.03, 1.75+/-0.02, 2.45+/-0.01, 2.15+/-0.01, respectively) and were all higher as compared to control group (0.75+/-0.02, 1.25+/-0.03, 0.65+/-0.03, 1.50+/-0.02, respectively) (P value is less than 0.05). However, the mRNA expression of PPARa decreased in No-treated group (0.85+/-0.02) compared with control group (1.45+/-0.02) (P value is less than 0.05). The mRNA expressions of CYP27A1, PPARa and CYP8B1 increased in treated group (1.25+/-0.01, 1.65+/-0.05, 1.65+/-0.02, respectively) and were all higher than that of control group (P value is less than 0.05).

CONCLUSIONAbnormal expressions of CYP7A1, FXR, CYP27A1, CYP8B1 and PPARa may play a role in pathogenesis of estrogen-induced intrahepatic cholestasis. Activator of PPARa may be used as therapeutical drug for ICP.

Objective:To establish a program for the prevention and management of parastomal hernia in patients with ostomy.Methods:Based on literature analysis and clinical needs, combined with the individual and family self-management theory (IFSMT), a preliminary plan for prevention and management of parastomal hernia was developed with the framework of case management model. Sixteen experts were selected for two rounds of Delphi expert consultations to analyze and screen indicators at all levels to calculate the expert′s positive coefficient, authority coefficient and coordination coefficient to analyze the credibility of expert consultation results.Results:The effective recovery rates of the two rounds of expert letter inquiries were 88.89% and 100.00%, the authoritative coefficients were 0.825 and 0.844, and the two rounds of Kendall′s W values were 0.221 and 0.269, which were statistically significant( P<0.01). The concentration of indicators is high. Finally, a programe for parastomal hernia prevention and management based on the self-management theory of individual and family consisting of 6 first-level indicators,16 second-level indicators and 42 third-level indicators was obtained. Conclusion:The programe for prevention and management of parastomal hernia based on individual and family self-management theory has high reliability and scientificity, and can provide a basis for the study of parastomal hernia prevention and management.

OBJECTIVETo study the quantified indices for describing the distributional status of diseases in the spatial point pattern analysis, and provide the a statistic in disease prevention and control.

METHODSG function, F function, J function and K function were summarized based on the inter-case distances from the view of spatial point pattern analysis. Through the introduction of the basic principles, these were used to analyze the data of acute schistosomiasis in the Guichi District, Chizhou City, Anhui province, with the study distances being from 0 to 3000 meters with 50-meter intervals. The findings were also validated by means of spatial moving scan window performed in SaTScan software.

RESULTSA total of 83 cases of acute schistosomiasis identified in Guichi District, and the point map showed that these cases were mainly distributed around the Yangtze and Qiupu rivers. The computational methods and characteristics of the four quantified indices were obtained. These acute schistosomiasis cases were also explored by using these indices, and the results showed that C and K functions were above 95% confidence interval. While, F and J functions were below 95% confidence interval. Ml these four indices showed that spatial clustering existed in the acute cases, which was consistent with the results of spatial moving scan window method. The latter method also found a most likely cluster, the coordinate of the circle center is (30.65 N, 117.44 E), radius is 2.69 km, and relative risk is 12.78 (DIR = 32. 80, P = 0. 0001).

CONCLUSIONThe quantified indices to describe the distributional status of diseases have not only solved the obstacle that spatial point pattern map which could only be analyzed qualitatively, but also supplied a theoretical foundation to deepen spatial clustering analysis.

OBJECTIVETo observe the activity of peripheral blood monocytes (PBMs) derived macrophage scavenger receptors (MSR) and changes of serum inflammatory factor in peripheral blood in patients with coronary heart disease (CHD), and to evaluate the effect of Ginkgo biloba extract (GBE) on the MSR activity, to explore the relationship between inflammatory factor and scavenger receptors activity as well as the possible mechanism of GBE in stabilizing the atheromatous plaque.

METHODSNinety-seven CHD patients with normal blood lipids were classified into the stable angina group, the unstable angina group and the acute myocardial infarction group, and 29 healthy persons were taken as control. Levels of C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) in all subjects were determined. And their PBMs were isolated, cultured in vitro, and transferred into macrophage to observe the effect of GBE on the expression of scavenger receptors.

RESULTSThe levels of MSR activity, CRP, sICAM-1 and sVCAM-1 in patients with acute myocardial infarction > unstable angina > stable angina > control.

CONCLUSIONGBE could down-regulate the MSR activity in CHD patients, which was positively correlated with levels of CRP, sICAM-1 and sVCAM-1. MSR activity could be taken as a monitoring criteria for active degree of vulnerable atherosclerosis plaque. GBE has the effect of suppressing MSR activity.
