Objective To study a multiple frequency tympanometry on ear system. Methods Based on the original low frequency and single ingredient SY-IA tympanometry, the study mainly focused on such aspects as multiple frequency probe tone circuit, constant pressure sound control system, micropressor control system and multiple frequency acoustic immitance & phase angle detection circuit. Results Multiple frequency tympanometry on ear system could detect multiple frequency acoustic immitance and phase angle for normal ear, tympanum loosed ear and ossicular chain break ear under different probe tone. Conclusion Experiments show that multiple frequency tympanometry on ear system based on ARM is helpful to the diagnosis of pathological changes which are insensitive to single low frequency tympanometry.

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 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 explore the change of cytoskeleton and the variance of Ca2+ in cultured cells during the invasion of Toxoplasma gondii. Methods Tachyzoites suspensions were gathered by routine method and used to infect phagocytic cells(J774A.1)and non-phagocytic cells (HUVEC). The ability of T. gondii invading into the cells and the influence of cytoskeleton inhibitor,colchicine and cytochalasin D,were observed by microscopy. The rearrangement of cytoskeleton of cells was observed by fluoromicroscopy. By using laser scanning confocal microscope,the variance of Ca2+ in J774A.1 and HUVEC was detected. Results Ca2+ increased greatly in J774A.1 during the invasion of T.gondii(P0.05). The microfilaments of J774A.1 were agglomerated during the invasion of T. gondii. Cytoskeleton inhibitor,cytochalasin D(P0.05)during the invasion and cytoskeleton was not changed. Cytochalasin D and colchicine showed little effect on the infection rate of HUVEC. Conclusion The concentration of Ca2+ increases greatly and cytoskeleton(mainly the microfilament)has been rearranged in phagocytic cell during the invasion of T. gondii,while both of them show no significant change in non-phagocytic cell.
