Objective To determine the incidence of thrombogenic events during the prostate operation period in patients discontinuing aspirin.Methods Among a retrospective cohort of 342 patients admitted in our institution for benign prostatic hyperplasia (or prostate cancer),combined with acute coronary syndrome (or stroke),we studied 4 patients who had not been taking aspirin before thrombogenic vascular event.Data on age,sex,vascular disease risk factors,and clinical outcome were collected.Results The 4 patients' mean age was 78.8±5.9 years.Each patient had at least two following risk factors:atrial fibrillation,old cerebral infarction and type 2 diabetes.80％ patients had a clinical history of hypertension.2 of the 4 patients stopped aspirin before a surgical procedure and developed acute ischemic stroke and acute myocardial infarction,separately.The other two patients developed acute ischemic stroke without aspirin prescription.The median time between admission and thrombogenic events was 15.5± 10.5 days.All patients were not given finasteride on admission.Conclusions This study should alert clinicians to know the risk of aspirin withdrawl perioperatively in patients at high risk of cardiovascular and cerebrovascular diseases.

Objective To investigate the risk factors of reversible posterior leukoencephalopathy syndrome (RPLS) in pre-eclampsia or eclampsia gravida. Methods This study was conducted in the Third Affiliated Hospital of Guangzhou Medical University between January 2013 and March 2016. A total of 100 patients who had no severe neurological diseases and were diagnosed pre-eclampsia or eclampsia, and underwent brain MRI were collected retrospectively. They were divided into 2 groups according to the MRI results, the RPLS group (n=49) and the non-RPLS group (n=51). The medical history, clinical symptoms and the results of laboratory examination were analyzed by the logistic regression, in order to explore the risk factors.Results In single factor analysis, HELLP syndrome, pregnancy associated with other diseases, poor prenatal care, grade 3 hypertension, elevated systolic blood pressure or diastolic blood pressure, elevated WBC, aspartate transaminase (AST), alanine aminotransferase (ALT), uric acid (UA) and lactate dehydrogenase (LDH), decreased platelet (PLT), headache, visual changes, seizures and conscious disturbance were more frequent in the RPLS group than those in the non-RPLS group (all P<0.05). According to the multivariate logistic regression analysis, the elevated WBC (OR=1.291, 95%CI:1.058-1.575, P=0.012), UA (OR=1.008,95%CI:1.001-1.016,P=0.032) and headache (OR=18.260, 95%CI:3.562- 93.607, P=0.000) were the independent risk factors.Conclusions Maternal history, clinical symptoms and some laboratory examinations might help in the early diagnosis of RPLS in pre-eclampsia or eclampsia gravida. Headache, the elevation of WBC and UA were the most significant factors.

Risk factors of hyperamylasemia in 152 diabetic ketoacidosis(DKA)patients who had no acute pancreatitis were examined.Serum levels of hemodiastase,natrium,kalium,chlorine,calcium,phosphonium,creatinine,carbon dioxide combining power,osmotic pressure,blood glucose,blood lipids and uric acid were measured.With hemodiastase and other 14 factors as independent variables,the multiple linear regression analysis was performed and the partial regression coefficient was estimated.Blood glucose,serum natrium,osmotic pressure and triglyceride entered the regression equation,and their partial coefficients were 10.26,10.35,2.21 and 8.00,respectively.The constant quantitv was -2162.06.Compared with amylase-normal group,hyperamylasemia group showed statistically significant difference in blood glucose,serum natrium,osmotic pressure and triglyceride levels.Higher blood glucose and triglyceride might be the primary causes of hyperamylasemia.

Objective To evaluate the effects of metabolic factors on the quality of 18F-fluorode oxyglucose (18F-FDG) myocardial metabolic imaging in coronary artery disease (CAD) patients with type 2 diabetes mellitus (T2DM). Methods Seventy CAD patients aged 60 years or over with T2DM were studied with myocardial 18 F-FDG dual isotope simultaneous acquisition (DISA) single photon emission computed tomography (SPECT). Fasting plasma glucose, total triglyceride (TG),total cholesterol (TC), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-eholesterol(LDL-C), insulin, C peptide and glyeosylated hemoglobia (HbAlc) were detected. Insulin resistance and islet β cell function were calculated by using the Homeostasis Model Assessment (HOMA) equation. Results Compared with the bad image quality group (36 cases), patients in the excellent image quality group (34 cases) were younger [with average age of (62.2±8.5) years vs. (67.6±8.3) years, P<0.01] and slimmer [with BMI of (24.7±2.6)kg/m2 vs. (26.1±2.5)kg/m2, P<0.05]. The levels of fasting insulin and C peptide were lower in the excellent image quality group than those in the bad image quality group [with fasting insulin level of 8.3 (5.1～12.4) mIu/L vs. 12.7,(6.1～17.9)mIu/L and C-peptide level of 0.6(0.5～0.9)nmol/L vs. 0.9(0.6～1.2)nmol/L, respectively,both P<0.05]. The HOMA insulin resistant index was reduced in the excellent image group [2.7(1.6～4.0) vs. 4.1(1.7～6.5), P<0.05]. Logistic regression analysis showed that obesity and age≥65 years were independent risk factors for image quality, with OR value of 3.73 (95% CI: 1.12～12.45,P=0.022)and 3.75 (95%CI:0.96～14.6,P=0.058)after adjustment of other metabolic factors. Conclusions Insulin resistance is the main factor that influences the quality of 18F-FDG myocardial metabolic imaging in patients with T2DM. In addition, age≥65 years and obesity are also risk factors for image quality.

Objective: To study the serum interleukin-37 (IL-37) level changes in patients with acute coronary syndrome (ACS) and to explore the relationship between IL-37 and coronary atherosclerotic plaque.
Methods: Our research included 3 groups. ACS group, n=60, SAP (stable angina pectoris) group, n=30 and Control group, the subjects with normal coronary artery, n=15. The peripheral serum levels of IL-37 were examined by ELISA and the differences were compared among different groups.
Results: ① The serum levels of IL-37 at admission were as ACS group < SAP group < Control group, P<0.05.②Intervention could transitionally decrease IL-37 level in SAP group. With 4 weeks treatment, IL-37 levels were signiifcantly increased in both ACS group and SAP group than admission time, while they were still lower than Control group, P<0.05.③The serum level of IL-37 at admission was negatively related to IL-18 (r=-0.79, P<0.05), the ratio of IL-18/IL-37 were as ACS group>SAP group>Control group, P<0.05.④In ACS group, IL-37 level was negatively related to GRACE score (r=-0.71, P<0.05), the ratio of IL-18/IL-37 was positively related to GRACE score (r=0.73, P<0.05).⑤The diagnosis of ACS could be basically excluded if the patients with IL-37>77ug/L.
Conclusion: The serum IL-37 might be involved in the inlfammatory process in ACS patients, it could be expected as an index for ACS monitor and evaluation in clinical practice.

Along with the development of society and the rapid economic growth in the past decades,hypertension and other chronic diseases have become important reasons for people's poverty caused by illness in China.This study collected a total of 5857 people from 2010 to 2013 randomly from the database of the Medical Insurance Department (MID),including 3229 people in Hubei province and 2628 people in Guangdong province.One-way ANOVA was used to compare the total medical expense,out-of-pocket (OOP)expense and hospital stay between variables.A multiple linear regression analysis was done to identify possible risk factors of total medical expense.The results showed that the average total medical expense per capita was 5709.89 yuan,and the medical expense per capita was 7053.58 and 4555.97 yuan in Guangdong province and Hubei province,respectively.The medical expense of hypertensive inpatients decreased from 7222.32 yuan in 2012 to 4894.66 yuanin 2013.There were no significant differences in medical expenses between different genders of hypertensive patients (P＞0.05).People of different ages,provinces,medical insurances and medical institution levels showed significant differences in medical expenses.The government should increase the investment in chronic disease management and treatment in the central and western regions to narrow the gap with the eastern region.Medical insurance fund payment should be improved to ensure the fairness of the use of medical services in different medical insurances.And measures should be taken to encourage chronic patients to visit primary medical institutions to effectively reduce medical expenses.

Objective The purpose of this study was to investigate the value of serum galactomannan (GM) in the diagnosis of invasive pulmonary aspergillosis (IPA) in patients with chronic obstructive pulmonary disease (COPD).Methods We enrolled 60 COPD patients in the study, including 19 IPA and 41 non-IPA cases.We examined serum GM of the patients by ELISA, evaluate the value of serum GM test for the diagnosis of IPA in patients with COPD, and compared the GM values before and after treatment.Results With 0.5 as the positive cutoff value, the sensitivity, specificity, positive predictive value, and negative predictive value of serum GM were 57.9%, 95.3%, 84.6%, and 83.0%, respectively, with a high specificity and a low sensitivity.The 7 IPA cases showed a significantly decreased GM value after treatment as compared with the baseline (0.30±0.21 vs 1.48±1.37, P=0.004).Conclusion The serum GM test has a limited value in the diagnosis of IPA in patients with COPD, but dynamic monitoring of the changes of the serum GM value may help evaluate the patient's condition.

OBJECTIVETo study the value and the clinical application of the Medical Image three-dimensional Visualization System of Abdomen (MI-3DVS) in diagnosis and evaluating resectability of pancreatic tumor.

METHODSTwelve patients with pancreatic tumor were tested with 64-slice helical CT (64-MSCT) angiography, and the CT data was reconstructed with MI-3DVS from November 2008 to August 2009. The 3D findings were adopted in diagnosis and evaluating resectability, and the results were compared with surgical operation and the pathological finding. There were 7 male and 5 female, aged from 14 to 83 years. Within the 12 cases, there were 4 cases with pancreatic carcinoma, 5 cases with pancreatic solid pseudopapillary tumor, 2 cases with pancreatic serous cystadenoma, 1 case with pancreatic cyst (ductal epithelial papillary hyperplasia).

RESULTSNine tumors which had been regarded as removable pre-operatively with MI-3DVS were removed successfully. Three patients who were considered unresectable by other hospitals with CT were operated successfully with MI-3DVS. The other 3 patients' tumors were actually not able to be removed as pre-operative evaluation.

CONCLUSIONMI-3DVS plays an important role in diagnosis and assessment of resectability of pancreatic tumor.

OBJECTIVETo explore cytological parameters that may identify the primary sites of metastatic adenocarcinomas in serous fluid.

METHODSSerous fluid specimens from 89 cases of metastatic adenocarcinomas (40 metastatic adenocarcinomas of lung, 6 metastatic adenocarcinomas of breast, 21 metastatic ovary adenocarcinomas, 22 metastatic gastrointestinal and pancreatic adenocarcinomas) were studied by using multiple morphologic parameters. Immunocytochemical S-P method was used to detect the expression of CA125, CA199, SPB and TTF-1 in 75 cases.

RESULTSMetastatic adenocarcinomas of different primary sites displayed certain different morphologic features, including the total amount of tumor cells, size of clusters, ratio of clusters over single cells, configuration of tumor clusters and the background of the smear. Cell clusters of small to medium sizes represented 95% and 100% in the metastatic adenocarcinomas of lung and breast, respectively. Most of the ovarian metastatic adenocarcinomas (85.7%) presented some large cell clusters and larger amount of cells, whereas certain metastatic gastrointestinal and pancreatic adenocarcinomas (45.5%) presented smaller number of cells and predominantly to be single cell in distribution (40.9%). Psammoma bodies were found in metastatic adenocarcinomas of lung and ovary. SPB and TTF-1 expression supported the diagnosis of adenocarcinoma of pulmonary origin. CA125 expression supported an ovarian origin. Although CA199 was seen in all groups of metastatic adenocarcinomas, nevertheless, its appearance in tumor cells in ascitic fluid specimens supported gastrointestinal and pancreatic origins.

CONCLUSIONMorpho-logic features of the cytological smear, immunohistochemical staining and clinical history are equally important in determining the primary sites of metastatic adenocarcinomas in serous fluid.
