Objective To explore variance and resource of intracellular free Ca2+ and extracellular arachidonic acid (AA) in different types of passage cells during the invasion of T. gondii. Methods The variance and resource of extracellular AA and intraceUular free Caz+ of Vero and J774A. 1 cells during the invasion of T. gondii were detected by multi-purpose scintillation counter and laser scanning confocal microscope. Data were analyzed using Chi-square test and t test. Results The intracellular free Ca2+ levels in J774A. 1 and Vero cells were both increased after T. gondii infection. The maximal changes of fluorescence intensity were (1 219.7±58.4)% (P＜0.01) and (356.3±23.6)% (P＜0.05), respectively.The increase of intracellular Ca2+ level in Vero cell was mostly from the release of intracellular Ca2+ store.And the Ca2+ increase in J774A. 1 cell was from both the release of intracellular Ca2+ store and extracellular Ca2+ influx. Extracellular AA levels were significantly increased in both Vero and J774A. 1 cells after T.gondii infection 5.02 and 8. 44 times respectively (t= 3. 124, t = 3. 852, P＜0.01). The AA elevations could be significantly inhibited by phospholipase A2 (PLA2) inhibitor pretreating T. gondii. Conclusions The phospholipase C of phagocytic host cell and PLA2 of T. gondii are activated by T. gondii infection,which results in the increase of intracellular free Ca2+ and extraeellular AA level. Combined actions of Ca2+and AA play a major role in the invasion of T. gondii to host cell. While only PLA2 of T. gondii may be activated in nonphagoeytic host cell.

Objective To selectively resect the lymph nodes in the endometrial cancer by risk factors evaluation pre-and intra-operation.Methods Three hundred and seventy-four cases who in the Obstetric and Gynecology Hospital Affiliated to Fudan University from Oct.2010 and Dec.2012 were clinically diagnosed as stage Ⅰ pre-and intra-operation,grouped as one (staged Ⅰ A,294 cases) and two (staged Ⅰ B,80 cases),and the situation of lymph nodes metastasis and the related risk factors were analyzed.Results (1) Lymph nodes metastasis were positive in 6 cases in group one (2.0％) and 12 cases in group two(15.0％),and the difference was significant between two groups (x2 =23.054,P =0.000).(2) University analyses showed that pathologic type,grade,myometrial invasion,lymphovascular invasion and cervical gland invastion were the risk factors contributed to the lymphatic metastasis in early staged endometrial cancer (P＜ 0.05).Multivariate analysis showed that myometrial invasion was independent risk factor affecting early metastasis of lymph node in endometrial carcinoma (regression coefficient =2.339,standard error =0.585,OR =10.897,95％ CI 3.273 ～ 32.367,P =0.000).(3)Based on the gynecology oncology group test and risk factors that recent used in different countries and clinical centers,superficial myometrial layer invasion,G2,age＞ 60 years,tumor ≥ 2 cm in diameter as the medium risk factors,and deep myometrial layer invasion,G3,lower portion of the uterus or cervical gland invasion as high risk factors,and patients with two or more medium risk factor (106 cases) and with one or more high risk factors(138 cases) were inclined to develop lymph node metastasis((5.66％ (6/ 106),0(0/130),P =0.04;8.70％ (12/138),2.54％ (6/236),P =0.007).(4) Two hundred and thirteen patients were found with superficial layer invasion by frozen section,and 11 of them were upgraded to Ⅰ B by postoperative pathologic examination.Interestingly,all of the 11 cases were accompanied by two medium or one of high risk factor.Conclusion Low incidence of lymph nodes involvement is found in stage Ⅰ endometrial cancer,especial stage Ⅰ A.Myometrial invasion is closely linked to lymph node metastasis,thus,lymphadenectomy should routinely be carried out in endmetrial cancer diagnosed as Ⅰ B whether pre-or intraoperation.As in stage Ⅰ A,unless two medium and one high risk factors are found.

Objective To investigate the clinical correlative factors of malignant cystic pancreatic tumors.Methods The clinical data of 45 patients who received cystic pancreatic tumor resection at the General Hospital of Tianjin Medical University from May 2000 to May 2011 were retrospectively analyzed.All patients were divided into benign tumors + precancerous lesions group (35 patients) and malignant tumor group (10 patients).The clinical symptoms and imaging features of cystic pancreatic tumors were analyzed.All data were analyzed by chisquare test or Logistic regression analysis.Results Abdominal pain,jaundice,emaciation,nausea and vomiting were observed in 23 patients (51％),and 22 (49％) patients had no clinical symptoms.The clinical features of benign pancreatic cyst included pancreatic calcification and pancreatic divisum,while the clinical features of malignant pancreatic cystic tumors were nodules,swelling of lymph nodes,dilation of biliary and pancreatic duct.The results of univariate analysis showed that age ≥ 60 years,presence of symptoms,jaundice,emaciation,dilation of pancreatic duct were the correlative factors of malignant cystic pancreatic tumors ( x2 =4.220,4.294,4.645,7.705,4.645,P ＜ 0.05 ).The results of multiple logistic regression analysis found that age ≥60 years,dilation of pancreatic duct and presence of clinical symptoms were the correlative factors of malignant cystic pancreatic tumors ( OR =1.573,2.674,2.723,P ＜ 0.05).Conclusion Age≥60 years,dilation of pancreatic duct and presence of clinical symptoms are the correlative factors of malignant cystic pancreatic tumors.

Objective To compare the glycemic control of different management approaches in type 1 diabetic mellitus (T1 DM) children,and to evaluate the influence factors associated with glycemic control.Methods This survey included 68 T1DM children from January 2012 to December 2014 in the Affiliated Hospital of Qingdao University of more than 1 year management.Hemoglobin A1c (HbA1c) levels were detected to assess glycemic control.Twenty-three T1DM children who participated in the World Diabetes Foundation(WDF) management program (group A) were compared with 45 T1DM children who were managed by themselves (group B).The clinical data were analyzed to explore the correlations with glycemic control.Results The HbA1c of 68 children was (8.86 ± 2.00)％,and only 21 cases (30.9％) had optimal HbAlc (HbAlc ＜ 7.5％).The level of HbA1 c of group A (7.60 ± 1.57)％ was significantly lower than that of group B[(9.40 ± 1.91) ％] (t =-4.045,P =0.001).Group A had less fluctuation in blood glucose than group B,which the duration more than 3 years.Duration (F =2.277,P =0.004),frequency of self-monitoring blood glucose (F =9.375,P =0.001),diabetic education (F =3.276,P =0.002),and diabetic diet (t =-2.046,P =0.025) were associated with glycemic control.Conclusions The glycemic control of T1 DM children at the Affiliated Hospital of Qingdao University was at the medium level,most of them haven't reached the target levels.The WDF management program could significantly and continuously monitor the glycemic level.Diabetic education and more frequent self-monitoring blood glucose and diabetic diet are associated with better glycemic control.

PurposeTo investigate the accuracy of18F-FDG PET/CT in diagnosing mediastinal and hilar lymph node metastasis of lung cancer and in guiding surgery. Materials and Methods Seventy-eight pathology-proven lung cancer patients underwent 18F-FDG PET/CT scanning and surgery. Histology was used as gold standard to evaluate the diagnosis of mediastinal and hilar lymph node metastasis.18F-FDG PET/CT was also compared to chest CT.Results The pathological examination confirmed metastasis lymph nodes in 105 out of 231 excised lymph nodes in 18 patients. No lymph node metastasis was found in mediastinum in the other 60 patients with lymph node staging of pN0. Lymph node staging was pN1 in 5 patients, pN2 in 11 patients, and pN3 in 2 patients. In all 78 cases, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of18F-FDG PET/CT were 80.9%, 94.7%, 91.0%, 85.0%, 93.1%; while 61.1%, 71.7%, 69.2%, 39.2%, 86.0% on chest CT. These were statistically different (χ2=4.325,P<0.05).Conclusion PET/CT is superior to plain chest CT examination as an accurate and efficient method in evaluating lymph nodes staging of lung cancer.
