Objective To explore the correlation of CT perfusion imaging with microvessel density (MVD) and vascular endothelial growth factor (VEGF) in hepatic alveolar echinococcosis (HAE).Methods Multi-slice spiral CT perfusion imaging was performed in 27 patients with HAE.Time-density curves(TDC) of the HAE peripheral area was drawn from the region of interest (ROI) with perfusion functional software.CT perfusion parameters including blood flow ( BF ),blood volume ( BV ),mean transit time(MTT) and permeability surface area product (PS) were calculated.MVD and VEGF expression of pathological specimens were examined by immunohistochemical staining with anti-CD34,anti-VEGF monoclonal antibody.The CT perfusion parameters,MVD and VEGF were compared in different types of TDC with t test.The correlation of CT perfusion parameters with MVD and VEGF were analyzed with Spearman test.Results In this group,21 cases which TDC lower than that of the liver were classified as type Ⅰ,the others 6 cases TDC higher than the liver were of type Ⅱ TDC.TDC perfusion parameters of the two types were as follows,BF:( 111.7 + 27.6),( 158.9 + 39.5 ) ml · 100 g- 1 · min - 1,BV:( 15.1 + 6.2),(26.8+8.4) ml/100 g,MTT:(7.0+4.4),(7.7+3.1) s,PS:(51.7 +17.3),(51.0+20.5) ml·100 g-1 · min-1.The significant differences of BF,BV and MVD[ (20.5 +5.4)/HP,(37.2 ±7.5)/HP,respectively ] were found between two types ( t =- 7.897,- 18.783,- 5.223,P ＜ 0.05,respectively).There were no significant differences in MTT,PS and VEGF expression(2.1 ± 1.0,3.2 ± 1.0,respectively)between two types of TDC(P ＞0.05).The correlation was found between the MVD and BF and BV in the type Ⅱ TDC group( r =0.789 and 0.878,respectively) and no correlation was found between MVD and each CT perfusion parameters in the type Ⅰ TDC group ( P ＞ 0.05 ).There was no correlation between the VEGF expression and CT perfusion parameters in two types of TDC ( P ＞ 0.05 ).Conclusion CT perfusion imaging with different type of TDC reflected different situation of angiogenesis in HAE peripheral area,which could be a potential technique to illustrate the microcirculation of this disease.

Objective To investigate the effects of dietary consumption of monounsaturated fatty acid (MUFA) on the control of type 2 diabetes mellitus. Methods One hundred and eighty-five patients with type 2 diabetes mellitus from a community in Shanghai were randomly divided into MUFA intervention group (MUFA group,n=125) and control group (n=60). The patients in MUFA group consumed tea oil enriched in MUFA for 3 months,while those in control group consumed normal oil. The serum glucose (fasting plasma glucose and 2-hour postprandial glucose),fasting insulin and blood lipid were examined before intervention and three months after intervention,and the parameters were compared within groups and between groups. Results The serum fasting glucose,fasting insulin,total cholesterol and low density lipoprotein-cholesterol 3 months after intervention were significantly lower than those before intervention in MUFA group (P0.05),while the serum fasting glucose,total cholesterol and low density lipoprotein-cholesterol in MUFA group were significantly lower than those in control group 3 months after intervention (P0.05). Conclusion Dietary consumption of MUFA can improve the glucose and lipid metabolism in patients with type 2 diabetes mellitus.

Objective To investigate the effect of leukotriene receptor antagonist montelukast on inflammatory factors in children with asthma.Methods Eighty children with moderate asthma who aged 6-14 years old were randomly assigned to 3 treatment groups:5 mg once daily montelukast,or inhaled 100 ?g twice daily budesonide and 5 mg montelukast with inhaled budesonide 100 ?g per day.Each dose group received medicine for 12 weeks.Before starting therapy and 12 months later,clinical effects were observed,and pulmonary function was measured in patients simultaneously;concentrations of serum and sputum eosinophil cationic protein(ECP), IL-5 and TNF-? were measured respectively;also the peripheral blood eosinophil (Eos)was counted.Results Following treatment,clinical evaluation was improved and there were significant increases in pulmonary function in asthmatic children.Compared with control group,the levels of serum ECP,IL-5,TNF-? and blood Eos counting increased significantly in asthmatic children.The blood Eos counting was significantly correlated with ECP concentration in serum of children with asthma(P

OBJECTIVETo study the therapeutic effects of posterolateral depression fractures of the tibial plateau through a modified anterolateral approach.

METHODSFrom February 2011 to January 2012,13 patients with posterolateral depression fractures of the tibial plateau were treated through a modified anterolateral approach. There were 8 males and 5 females, ranging in age from 28 to 59 years old (49.2 years old on average). Data from patients were collected retrospectively as follows: X-ray, time of fracture healing and the complications of fracture healing. The patients were evaluated both clinically and radiologically according to the Rasmussen score system.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 18 months (mean 13.7 months). All the patients got bony union. The average radiographic bony union time was 15.1 weeks (ranged, 11 to 17 weeks). No case of secondary articular depression was found. No complications such as malunion or joint stiffness were found. But 1 patient had superficial infection and 1 patient had common peroneal nerve injury. According to the Rasmussen score system,the mean radiological score was 16.50 ± 0.67 (ranged, 13 to 18), and the mean functional score was 25.20 ± 2.21 (ranged, 13 to 30). The mean range of knee motion was (125.3 ± 9.3)° (ranged, 0° to 135°).

CONCLUSIONTreatment of depression fractures of posterolateral tibial plateau with a modified anterolateral approach is a safe method with effective exposure, due to its stable fixation and relatively good outcome with minimal soft-tissue complications. It is regarded as an ideal procedure for depression fractures of posterolateral tibial plateau.
