Background and purpose: The role of lymphadenectomy for endometrial cancer is still controversial. Few gynecologists in China carry out pelvic and/or para-aortic lymphadenectomy for patients with endometrial cancer. The aim of the current study was to investigate the role of systematic lymphadenectomy in the treatment strategy of endometrial cancer and the feasibility in carrying out the surgery. Methods: We performed a retrospective chart review of all patients with endometrial cancer who experienced surgical staging at Cancer Hospital, Fudan University from January 2005 to July 2008. Lymph nodes metastatic status, alteration of adjuvant therapy and surgical complications were discussed. Results: Nineteen (14.8%) of 128 patients undergoing systematic lymphadanectomy had lymph node metastases: both pelvic and para-aortic in 7 patients, only pelvic in 8 patients, and exclusively isolated to the para-aortic area in 4 patients. Therefore, more than half of the patients with lymphatic dissemination had para-aortic lymph nodes metastases. Tumor grade, histological type, myometrial invasion and lymph-vascular space invasion were associated with lymph nodes metastases. Adjuvant chemotherapy and/or tumor-directed radiotherapy were needed for 15 patients upstaged due to lymph-nodal invasion (P<0.05). Furthermore, adjuvant therapy was eliminated for 50 intermediate/intermediate-high risk patients with negative lymph nodes and extrauterine spread. Complications were found in 8 patients: 3 pelvic infection, 2 residual vaginal bleeding, and 1 pero-bowel obstruction, 1 deep venous thrombosis accompanied with lymphocyst, and 1 lacunar infarction. The median time of the procedure was 150 minutes, median blood loss was 300 mL, and 27 patients received blood transfusion. Conclusion: The findings of the current study suggest that it is safe and feasible to carry out systematic lymphadenectomy in women with endometrial cancer. Surgical staging can assess the status of lymph nodes, provide accurate prognostic information, and help to formulate adjuvant therapy after surgery.

Objective The aim of this study was to find whether modified radical hysterectomy or radical hysterectomy improves local-regional control for patients with stage Ⅰ endometrioid carcinoma. Methods The medical records of patients with stage Ⅰ endometrioid carcinoma who were enrolled in Cancer Hospital of Fudan University between 1996 to 2008 after undergoing modified radical hysterectomy or radical hysterectomy were reviewed.The Kaplan-Meier method was used for time-to-event analysis with recurrence and death as the end points. Results Among 518 women with stage Ⅰendometrioid carcinoma, 474 underwent modified radical/radical hysterectomy and bilateral salpingo-oophorectomy±pelvic lymphadenectomy±peri-aortic lymphadenectomy+cytology.Twelve patients (2.5%) received neoadjuvant chemotherapy or vaginal brachytherapy before operation, and 73 patients (15.4%) received postoperative adjuvant therapy (pelvic external beam radiotherapy or chemotherapy or combination).After a median follow-up of 30 months,16 relapses were observed.Eight patients suffered with distant metastases, 4 with vaginal recurrences and 4 with pelvic recurrences.The 3-year and 5-year cumulative vaginal recurrence rates were 1.4% and 2.0%. The 3-and 5-year cumulative local-ragional recurrence rates were 2.5% and 3.1%. The 3-and 5-year actuarial overall survival rates were both 98.1%.The 5-year local-regional recurrence rates for stage Ⅰa, stage Ⅰb, stage Ⅰc were 3%, 3.7% and 0 (P=0.649), and the 5-year survival rates were 98.3%, 97.8% and 100% (P=0.399). There was no evidence of benefit in terms of lympnadenectomy in patients with stage Ⅰ endometrioid carcinoma(P value were 0.525 and 0.665,respectively).The median operating time was 135 minutes, the median blood loss was 300 mL, and 15.4% of the patients needed blood transfusion. Surgery associated morbidity was 7%, and no one died of surgery associated morbidity. Conclusions Modified radical hysterectomy or radical hysterectomy is a viable and possibly preferable option for patients with stage Ⅰ endometrioid carcinoma.Randomized clinical trials were urgently needed to address the utility of modified radical hysterectomy in stage Ⅰ endometrial cancer.

Background and purpose:With the recognition of prognostic factors and application of surgical- pathological staging,the treatment strategy of endometrial cancer has greatly changed.In this study,we investigated the treatment strategy,survival rate and prognostic factors of endometrial cancer.Methods:Five hundred and fifty-nine patients of endometrial cancer underwent primary surgical treatment from January 1996 to December 2006 in Cancer Hospital,Fudan University.The clinicopathologic parameters and prognosis were analyzed retrospectively.Results: Patients were followed up with the median period 36 months,25 cases experienced local relapse,24 cases were found to have distant metastases.The 3-year overall survival(OS)was 88.7%,3-year and 5-year disease free survival(DFS) was 82.7% and 80.9%.The 3-year overall survival(OS)were 95.5% in stageⅠ,95.3% in stageⅡ,75.9% in stageⅢand 32.4% in stageⅣrespectively(P

Objective To determine the difference of macrophage RAW264.7 apoptosis induced by Brucella melitensis virulent strain 16M and attenuated strain M5-90 and elucidate the regulatory role of caspases 3,8 and 9.Methods The best multiplicity of infection (MOI) was determined through kinetic analysis of Brucella melitensis strain 16M and M5-90 induced mouse macrophages apoptosis(bacterium ∶ cell =100 ∶ 1,50 ∶ 1,10 ∶1).The infection model was established using the best MOI =50 ∶ 1.The numbers of in vivo bacteria by colony formation units were calculated after macrophages were infected for different times,including 2,4,8,12,24 and 48 h,and the infected cells were collected.The ratios of apoptosis were detected and the regulation of caspases 3,8 and 9 in apoptosis pathway was elucidated by flow cytometry.Results The numbers of 16M in vivo bacteria were 105.4,104.8,105.8,106.5,108.0 and 109.0,respectively and of M5-90 were 106.1,106.2,106.4,106.3,106.1 and 105.0,respectively.The number of in vivo bacteria of 16M was significantly increased than that of M5-90 after infected for 24 h to 48 h.The ratios of apoptosis induced by 16M after infected for 2,4,8,12,24 and 48 h was (2.67 ± 0.09)％,(13.13 ± 0.30)％,(6.56 ± 0.42)％,(6.49 ± 0.28)％,(16.07 ± 0.86)％ and (24.23 ± 1.67)％,respectively,and by M5-90 was (3.62 ± 0.02)％,(32.01 ± 2.59)％,(17.58 ± 0.44)％,(16.09 ± 0.10)％,(62.53 ± 2.70)％ and (85.53 ± 0.15)％,respectively,and by control group was [(1.90 ± 0.20)％,(1.92 ±0.16)％,(1.99 ± 0.03)％,(2.48 ± 0.11)％,(3.56 ± 0.07)％,(5.26 ± 0.33)％].The differences were statistically between groups in same time.The Brucella melitensis vaccine strain M5-90 was more powerful than virulent strain 16M in respect of inducing macrophage apoptosis after infected for 24 to 48 h.Twenty-four hours after infection,the expression of caspases 3,8 and 9 was (1.47 ± 0.05)％,(1.52 ± 0.02)％ and (2.47 ± 0.12)％,respectively,in control group and the expression was (9.70 ± 0.46)％,(6.08 ± 0.56)％ and (35.08 ± 1.64)％,respectively,after infected for 24 h induced by M5-90.The expression of caspases 3,8 and 9 was significantly higher than that control group (P ＜ 0.01).Twenty-four hours after given caspases 3,8 and 9 inhibitor,apoptosis rate in control group was (66.72 ± 1.28)％,in M5-90 group was (22.58 ± 0.55)％,(53.15 ± 1.85)％ and (29.18 ± 0.23)％,respectively,and compared with control group,apoptosis rate of caspases 3,8 and 9 was significantly lower(P ＜ 0.01).Conclusions Apoptosis of macrophage can be induced by Brucella melitensis virulent vaccine strain 16M and attenuated strain M5-90.M5-90 is stronger than that of strain 16M.Caspases 3,8 and 9 can regulate macrophage apoptosis after M5-90 infection.

Objective To investigate the effect of intraocular injection of mixed crystalline in vivo on survival of retinal ganglion cells(RGCs)after optic nerve cut.Methods Twenty Long-Evens rats were divided into normal control,and 7 day,14 day,and 21 day groups after optic nerve was cut off.There were 5 eyes in each group.Mixed crystallin(1x10~(-4)g/L)and isotonic saline solution were injected into the vitreous of fight eye and left eye respectively.The number of RGCs was counted 7,14 and 21 days after optic nerve cut.Results The density of RGCs declined clearly 7 days after optic nerve cut.In the group with crystallin injection,the density of RGCs declined to 71%,32% and 15% of the control group repec- tively,much higher than that of the controls on days 7,14 and 21 after optic nerve was cut off(P

Hyponatremia is relatively common in patients with neurologic disorders, while its diagnosis and treatment remain controversial. Osmotic demyelination syndrome (ODS) has shown to be closely associated with hyponatremia. ODS patients often present as central pontine myelinolysis, extrapontine myelinolysis, or both. This article reviews the clinical manifestations, pathogenesis, and risk factors of ODS in patients with hyponatremia caused by neurologic disorders.

Objective To evaluate prognostic factors and treatment of patients with advanced stage endometrial cancer. Methods One hundred and eighteen patients with advanced stage endometrial cancer were treated in our hospital between January 1996 and December 2006. The treatment and prognosis were retrospectively analyzed. The mean follow-up time was 26 months. Results During the follow-up, 33 cases (28.0%) died and 25 patients(21.2% ) had disease progression. The 3-year overall survival for patients with stage Ⅲ and stage Ⅳ was 78. 3% and 39. 4%, and for endometrioid and nonendometrioid endometrial carcinoma was 69. 3% and 42. 0%, respectively. Four patients with positive cytology only were followed closely after surgery and were free of disease up to the report time. Patients with late stages, deep myometrial invasion, nonendometrioid endometrial cancer, poor differentiation, without lymphadenectomy and without radiochemotherapy after surgery were associated with a worse prognosis by univariate analysis (P < 0. 05 ),while in a multivariate analysis only late stages and deep myometrial invasion were associated with a poor prognosis ( P < 0. 05 ). The patients who received lymphadenectomy and whose residual disease after the surgery was less than 1 cm had better prognoses than those otherwise(P <0. 05). The patients who received postoperative radiochemotherapy had better prognoses than those who did not ( P <0. 05 ). Conclusions Pathological stage and myometrial invasion are independent prognostic factors for late stage endometrial cancer. Satisfactory cytoreduction surgery and lymphadenectomy, followed by postoperative radiochemotherapy, except for stage Ⅲa patients with positive cytology only, are recommended in order to improve prognosis.
