Objective To summarize the clinical characteristics of recurrent endometrial carcinoma.Methods A total of 22 cases of recurrent endometrial carcinoma from January 2006 to December 2015 were enrolled.Primary diagnosis of endometrial carcinoma were made in our hospital,with complete clinical data and standard NCCN staging operation.The recurrence of endometrial cancer was confirmed by pathological diagnosis after second surgery or biopsy.Clinical data were retrospectively analyzed.Results The median age of primary diagnosis was 52 years old (rang,44-63 years old).And the most common clinical symptom was postmenopausal vaginal bleeding (54.5％,12/22).There were 18 cases (81.8％) of endometrial adenocarcinoma,3 cases (13.6％) of serous adenocarcinoma,and 1 case (4.5％) of clear cell carcinoma.As to the muscular layer infiltration,there were 14 cases (63.6％) ＜ 1/2,7 cases (31.8％) ＞ 1/2 and 1 case (4.5％) involving the whole layer.There were 4 cases (18.2％) of positive pelvic lymph node and no para-aortic lymph nodes metastasis.As to the postoperative clinical pathologic stage,there were 12 cases (54.5％) of FIGO Ⅰ A,5 cases (22.7％) of FIGO Ⅰ B,1 case (4.5％) of FIGO Ⅱ,and4 cases (18.2％) of FIGO ⅢC1.The median recurrent time was 4 years (rang,1.5-7 years),without obvious self-conscious symptoms,including serum CA125 elevated in 12 cases (54.5％) and positive ultrasound,CT or X-ray examination findings in 10 cases (45.5％).As to the recurrence location,14 cases (63.6％) were in the pelvic cavity,6 cases (27.3％) of retroperitoneal lymph nodes,1 case (4.5％) of anterior abdominal wall accompaning lung metastasis,and 1 case (4.5％) of lung metastasis.Three patients accept Lynch syndrome screening,of which 2 cases were positive.Conclusions Muscular layer infiltration is common in recurrence of endometrial cancer,with no obvious clinical symptoms.Pelvic cavity is the most common location of recurrence.

Objective To compare the costs of laparoscopy and laparotomy in the operative treatment of ovarian cysts. Methods Patients with ovarian cysts who were operated on by laparoscopy (83) or by laparotomy (65) in the Peking University Third Hospital from June 2000 to August 2001 were retrospectively analyed.Patients' hospital stay,time taken for the patients to return to work,hospital charges,costs because of inability to work and total costs (including the direct medical costs,direct non-medical costs and indirect costs) were compared between the two groups. Results The mean hospital stay and the mean time taken for the patients to return to work were statistically shorter in the laparoscopy group than those in the laparotomy group.The mean hospital charges were significantly higher and the mean costs of without work were significantly lower in the laparoscopy group.The total costs in the two groups were similar (no significant difference). Conclusions According to the mean income of the people in Beijing,the costs of laparoscopy in the operative of the ovarian cysts are not higher than that of lapatomy.

Through approaching the mixed ability training of clinical post-graduates, the following conclusions were drawn: necessity to take turns in the clinical specialties, establishment of its program, the details and contents were pointed out, meanwhile, it is necessary to guarantee progression of the plan and its training effects, and to improve the cultivation quality.

From the perspective of portable monitoring devices,we use an analog front-end AFE4490 design a module of Non-invasive blood oxygen measurement, used to collect human pulse wave signal and peak (valley) value detection and then use the principles of non-invasive oximetry calculated oxygen saturation (SPO2). This design of noninvasive oximetry module has the characteristics of small size, low power consumption, and the results of test show that the measurement of oxygen saturation are correct.

Objective To study the curative effect of breast-conserving therapy in patients with breast cancer.Methods 100 cases with breast cancer were divided into breast-conserving therapy 50 cases and radical therapy 50 Cases.The primary manner was wide excision of tumor and dissection of axillary lymph node.Adjuvant radiotherapy,chemotherapy and incretion treatment were given postoperatively.Results In 100 cases of breast cancer,the surviral of 83 cases(83.0%),17 patients(17.0%)died,30 cases(30.0%)of metastasis,local recurrence in 13 cases (13.0%);ER,PR-positive are 62 cases(62.0%),both wholly negative in 18 cases(18.0%),ER-positive only 12cases(12.0%),only 8 cases(8.0%)of PR positive;comparing two groups,survival and recurrent rate had no significant difference(X2=3.503,X2=4.284,P＞0.05),metastasis rate was significant different(X2=6.789,P＜0.05);satisfaction degree was 99.0% more than 12 months,and got ideal appearance was over 90%.Conclusion Breastconserving therapy can get long-term effect like Auchineol's.Breast-conserving therapy can gain good cosmetic resuits.

Objective To detect the microvessel density(MVD) marked by MIF protein in esophagus squamous cell carcinoma(ESCC), and to see if a relationship exists between microvessel density(MVD) and clinicopathologic features. Methods The expression of MIF in vascular endothelial cell in forty ESCC specimens was examined by immunohistocbemistry staining, calculated the mean of MVD and analysed the relationship with clinicopathologic features. Results The positive rate of MIF protein was 95.00 %(38/40) in ESCC vascular endothelial cell. Compared with the normal esophageal squamous tissue[32.50 %(13/40)], there was significant difference in statistics, the mean of MVD was 26.5±8.5. MVD was positively correlated with the tumor TNM stages and lymph node motastasis. Conclusion MIF can be used in tagging vascular endothelial cell, MVD of ESCC was positively correlated with the tumor TNM stages and lymph node metastasis. It might be an major prognostic factor in ESCC.

Aim To study the effect of proteasome inhibitor MG132 on the expression of caspase-3 and apoptosis in cultured human umbilical vein endothelial cells.Methods Human umbilical vein endothelial cells was treated with MG132 (2,5 ?mol?L~(-1)) for 24 h. The apoptotic cells were determined by DNA fragment analysis and flow cytometric analysis. The level of caspase-3 mRNA was quantified by reverse transcription-polymerase chain reaction (RT-PCR). The protein contents of caspase-3 were analyzed by immunocytochemistry.Results The results showed that the increase of the degree of human umbilical vein endothelial cells apoptosis was concentration dependent. MG132 could up-regulate the gene/protein expression of caspase-3.Conclusions The results implicated that proteasome inhibitor MG132 induced human umbilical vein endothelial cells apoptosis by accumulation of caspase-3.

Objective To explore the clinical value of MRI in diagnosing and treating cesarean scar pregnancy (CSP).Methods A retrospective analysis was conducted on the clinical manifestations of 54 patients diagnosed with CSP between January 2009 to January 2013 in Peking University Third Hospital.Based on the patients' MRI image and other clinical datas,we did transvaginal operation on patients with CSP1,and transvaginal combined with abdominal operations on patients with CSP2.The intraoperative blood loss,operation time,postoperative hospital stay,and the length of time required for of serum hCG dropping to normal of the patients were analyzed.Results The average age of the 54 patients was (34±5) years and the average duration of gestation was (56± 16) days,all patients' vital sign were stable,the hCG level was 23-142 962 U/L before treatment.Twelve patients were diagnosed with CSP1 by MRI,and 5 of them had focus of 1-2 cm in diameter,the 5 patients' serum hCG level was 436-1 159 U/L and 23-32 days after drug administration,their hCG level returned to normal; the other 7 patients had focus of 2.0-4.4 cm in diameter,and their hCG level was 2 218-63 446 U/L,lesion resection was done on the 7 patients by hysteroscope or under B-uhrasound monitor.Forty-two patients were diagnosed with CSP2,and their focus were 1.0-7.1 cm in diameter,and serum hCG level were 23-142 962 U/L.We did bilateral uterine artery occlusion by laparoscope or laparotomy during operation for 22 patients or bilateral uterine artery embolization (UAE) before operation for 20 patients,then we did lesion resections.The blood loss during operation of CSP1 or CSP 2 was 50.1,267.2 ml; operation time was 30,128 minutes; postoperative hospital stay was 4.6,6.7 days;their serum hCG returned to normal 13-30 days after the surgery.All the 54 patients' uterus were preserved,and the patients undergoing operations were all cured without the second operation.Conclusion MRI is an effective method to conduct clinical treatment in CSP.
