Objective To study the clinical and pathologic features,histological criteria and pathologic factors contributing to diagnosis of mixed epithelial and mesenchymal tumors(mixed m?llerian tumors,MMT)of the uterus.Methods A retrospective study of 102 cases of MMT of the uterus (74 adenofibromas including 9 recurrent cases,3 atypical polypoid adenomyomas,2 carcinofibromas,10 adenosareomas and 13 carcinosarcomas)was undertaken.Clinical records,gross features and tissue slices were reviewed.The follow-up data were analysed.Results The most common symptom was vaginal bleeding.Clinical signs included pelvic mass,uterine polyps,and enlarged uterus.Benign MMT usually presented as exophytic polypoid masses extending into the uterine cavity or protruding through the external os,often broad-based,lobulated and papillary.It was hard to distinguish low-grade malignant MMT from the benign ones by gross appearance.High-grade malignant MMT had the common gross features of carcinoma and sarcoma.Histologically,MMT showed a biphasic differentiation of mesenchymal and epithelial components.MMT were classified according to whether these elements were benign or malignant.Nine cases of adenofibroma without unique features for the diagnosis of adenosarcoma recurred at postoperative intervals of 3 to 96 months.Recurrent tumors were almost always confined to the original site.Conclusions Uterine MMT tumors according to WHO diagnostic criteria are not rare.The differential diagnosis depends on a multifactorial analysis.The recurrent adenofibromas may be a kind of borderline tumors with benign appearances and malignant behavior.

Objective To investigate the relationship between proteinuria components and the severity of pregnancy induced hypertension syndrome (PIH), the unconcentrated urine samples from patients with PIH were analyzed on proteinuria components by electrophoresis.Methods Proteinuria components were analyzed by sodium dodecyl sulfate-agarose gel electrophoresis (SDS-AGE) in unconcentrated urine samples from PIH patients (PIH group,n=114) and normal third trimester pregnant women (control group,n=110).Results Eleven kinds of urinary protein were detected in the PIH group and four in the control group. The results showed positive relationship between the urine protein component complexity and the severity of PIH (P

To compare the effects of four different intensive insulin therapies on blood glucose control and vascular endothelial function in newly-diagnosed type 2 diabetes.Patients were randomly divided to accept pre-meal insulin aspart 30 or pre-meal insulin aspart and glargine at bedtime or pre-meal Novolin-R and NPH at bedtime or continuous subcutaneous insulin aspart infusion.Capillary blood glucose determination and continuous glucose monitoring system were carried out,therapeutic time and total insulin dosage were recorded.Ultrasound was used to evaluate the vascular endothelial function.Glucose level,incidence of low glucose,potency ratio of the four groups were similar( P＞0.05 ) ; FMD and NMD were not significantly improved ( P =0.718,P =0.065 ).The short-term efficacy and safety of the four groups are similar.The short-term intensive insulin therapy has no obvious effect on vascular endothelial function.

Objective To survey the knowledge requested by patients with coronary artery disease (CAD) after stent implantation.Methods A survey on CAD and stent-related knowledge requested by CAD patients with stent implantation was conducted with a self-designed questionnaire from September 2013 to November 2013.Total 362 patients (235 males and 127 females) aged (67 ± 12) years participated in the survey in Yuetan Community Health Service Center and Fuxing Hospital in Beijing.Open questions and heuristic questions were used together during the survey.Results The knowledge requested by patients were:diet management(255,70.4％),side effects of medication(241,66.6％),management of physical activity (221,61.0％),prevention of CAD(181,50.0％),withdrawal of medication(176,48.6％),the life of stents (168,46.4％),post-operation check-up items (162,44.8％),the causes of CAD (156,43.1％)and drug mechanisms(134,37.0％).Patients with stent implantation less than one year requested more knowledge about the cause of CAD (x2 =37.4,P ＜ 0.001),life-time of stent (x2 =39.9,P ＜0.001),prevention of CAD (x2 =13.4,P =0.001),post-operation check-up items (x2 =21.2,P =0.001) and requested less knowledge about withdrawal of medication (x2 =9.56,P =0.008),diet management (x2 =6.49,P =0.04) than those with more than one year.Patients aged ＜ 70 years requested more knowledge about the cause of CAD (x2 =31.6,P ＜ 0.001),prevention of CAD (x2 =9.99,P =0.007),life-time of stent (x2 =79.1,P ＜ 0.001),side effects of medication (x2 =7.84,P =0.02) than patients aged ＞ 70 years.Patients with education higher than junior high school requested more knowledge about the cause of CAD (x2 =26.6,P ＜ 0.001),prevention of CAD (x2 =14.4,P =0.001) and life-time of stents (x2 =7.82,P =0.02) than those with education lower than junior high school.Patients with education higher than junior college requested more knowledge about the cause of CAD (x2 =26.6,P ＜ 0.001) and post-operation check-up items (x2 =10.7,P =0.005) than those with education lower than junior college.Conclusion Some factors affect the knowledge requested by patients with coronary artery disease (CAD) after stent implantation,which should be considered in health education for CAD patients.

Objective To investigate the mechanism of protective effects of resveratrol on tissueengineered cartilage.Methods The chondrogenesis of alginate-encapsulated bone marrow mesenchymal stem cells (BMSCs) were evaluated by toluidine blue staining and immunostain.The morphology of BMSCs-derived chondrocytes cultured on chitosan-gelatin scaffolds (CGS) was evaluated by scanning electron microscope and laser confocal microscope.When these cells on CGS were pre-stimulated with interleukin-1β (IL-1β) or cotreated with IL-1β and resveratrol in the absence and presence of specific β1-integrin blocking antibody,collagen type Ⅱ,aggrecan,matrix metalloproteinase-13 (MMP-13) expression,and the translocation of nuclear factor kappaB (NF-κB) were analyzed by Western blotting.ANOVA was used for statistical analysis.Results Alginate bead culture plus conditional medium together could induce the cartilage-specific collagen type Ⅱ,aggrecan expression and extracellular matrix accumulation in differentiated chondrocytes.CGS supported differentiated cell attachment,proliferation,and migration.When those cells cultured on CGS were stimulated with IL-1β alone,collagen type Ⅱ and aggrecan expression was inhibited.However,MMP-13 expression increased.By Western blotting semi-quantitative analysis,the expression level of cartilage-specific collagen type Ⅱ of the control group was 0.484±0.006; the expression level of resveratrol intervention group was 0.474±0.014.The difference between these two groups was not statistically significant (P＞0.05).The expression level of the IL-1β intervention group reduced to 0.155±0.009,which was statistically significant different from the above two groups(P＜0.05).Resveratrol could antagonist the negative effect of IL-1β,and increase collagen type Ⅱ to 0.468±0.014,the difference between these two was statistically significant (P＜0.05),and no significant difference when compared to the control group (P＞0.05).Specific β1-integrin blocking antibody could abrogate these effects of resveratrol,decrease collagen Ⅱ expression to 0.169±0.011,the difference was significant (P＜0.05),but there was no difference when compared to the IL-1β group (P＞0.05).Aggrecan semi-quantitative expression has the same trend in the expression of type Ⅱ collagen while the expression of MMP-13,NF-κB had the reversal trend.These indicated that the resveratrol reversed the catabolic effects by reducing the nuclear translocation of NF-κB.Specific β1-integrin blocking antibody abrogated these effects of resveratrol.Conclusion Resveratrol,by regulating β1-integrin,acts as a NF-κB nuclear trans-location inhibitor to protect tissue-engineered cartilage.

Objective To evaluate the combined impacts of blood glucose and its related metabolic factors on 18F-FDG uptake by liver.Methods A total of 544 subjects (384 males and 160 females, age range 24-73 years) undergoing 18F-FDG PET/CT were recruited in this retrospective study.SUVmean of the right lobe of liver was calculated.Two-sample t test and one-way analysis of variance were performed to compare SUVmean between patients with different genders and BMI levels.Linear correlation analysis, partial correlation analysis and multiple linear regression analysis were conducted to evaluate the relationship between age, injected 18F-FDG dose, blood glucose, serum T3, T4, FT3, FT4, BMR, BMI and liver SUVmean.Results The SUVmean of the liver in males and females were 1.89±0.42 and 1.92±0.38 (t=0.693, P>0.05), but it was significantly different among BMI groups (F=3.056, P<0.05).Age, blood glucose and FT3 were significantly associated with liver SUVmean (r′ values: 0.108, 0.140 and 0.105, all P<0.05) and were independent factors that indicated variation of liver SUVmean (β values: 0.006, 0.070 and 0.088, all P<0.05).Blood glucose was the strongest powerful predicting variable of liver SUVmean (β′=0.154, P<0.001).Conclusions Blood glucose and its related metabolic factors can affect the liver 18F-FDG uptake.Age, FT3, blood glucose are independent factors predicting variation of liver SUVmean.The impact of glucose metabolism status should be considered when assessing liver 18F-FDG uptake.
