Serum tumor biomarkers are significant for the early diagnosis and treatment,preoperative evaluation,prognosis prediction and relapse surveillance of endometrial carcinoma.Recently,serum CA125 and human epididymal secretory protein 4 are widely recognized as closely related with staging,metastasis and prognosis of endometrial cancer.In addition,the serum miRNAs are characterized by their features of high stability and specificity.Omics studies will be helpful for the general assessment of the initiation and progression of endometrial cancer.Insights into these two aspects will facilitate the identifications of new biomarkers with higher sensitivity and specificity for endometrial carcinoma.

Objective To ivestigate the clinical outcomes of domestic Sirolimus-eluting stents(Partner stents)in unselected patients.Methods We reviewed the clinical data of 516 patients who had implanted the Paterner stents during August 2006 to Dotober 2007.We followed up all the patients by telephon or by clinical visits for(9?2)months.The incidence of MACE and the result of follow up angiogram was analysed.Further investigation was made in the relation between the restenosis rate and lesion morphorlogy.Results A total of 872 Partner Stents were implanted successfully in 516 patients.Among them,482 patients(93.4%)finished the clinical follow up and 239 patients(46.3%)received follow up angiogram.The MACE rate was 3.5% and the restenosis rate was 11.3% as share in angiogram.A 14% of the patients with reslenosis was concomitant with diabetes mellitus.We analysised the rate of restenoses of left main,bifurcation,chronic total occlusion,diffuse disease,in-stent restenoses,littile vessal,acute occlusion,ostial lesions,and just A-just lesion.Conclusion Implantation of domestic Partner stent was safe and effective,even in patients with diabetes mellitus.The MACE rate was low and the stent has shown satisfactory ontcomes in lesions such as left main,bifurcation,chronic total occlusion,diffuse disease,in-stent restenoses,littile vessal,acute occlusion,ostial lesions,and A-type lesion.

Objective To evaluate the effect of calcitonin gene-related peptide (CGRP) on anoxiareoxygenation (A/R)-induced injury to neonatal rat cardiomyocytes incubated in high glucose medium.Methods Cardiomyocytes were obtained from 1-3-day old Sprague-Dawley rats and cultured in the culture medium containing 15％ bovine calf serum and then seeded onto 6-well plates at a density of 10 × 105/ml (3 ml/well).The cells were randomly divided into 5 groups (n =9 each):normal glucose medium control group (NG group),high glucose medium group (HG group),high glucose medium + A/R group (HG+ A/R group),high glucose medium + A/R + CGRP group (HG + A/R + CGRP group),and high glucose medium + A/R + CGRP+ CGRP8-37 group (HG + A/R + CGRP + CGRP8-37 group).The cells were incubated in normal glucose (5.5 mmol/L) medium for 72 h in NG group.In HG group,the cells were incubated in high glucose (25.0 mmol/L) medium for 72 h.In HG + A/ R group,the cells were incubated in high glucose medium for 72 h and then exposed to 3 h of anoxia followed by 2 h of reoxygenation.In group HG + A/R + CGRP,the cells were incubated in high glucose medium for 72 h,CGRP (final concentration 10-8 mol/L) was then added to the culture media and the cells were incubated for 1 h and then underwent A/R.In HG + A/R + CGRP + CGRP8-37 group,the cells were incubated in high glucose medium for 72 h,CGRP (final concentration 10 8 mol/L) was then added to the culture media and the cells were incubated for 1 h and then underwent A/R.In HG + A/R + CGRP + CGRP8-37 group,the cells were incubated in high glucose medium for 72 h,CGRP8-37 (final concentration 10-8 mol/L) and CGRP8-37 (CGRP receptor antagonist,final concentration 10-7 mol/L) was then added to the culture media and the cells were incubated for 1 h and then underwent A/R.Apoptosis in cardiomyocytes was detected using TUNEL and apoptosis index (AI) was calculated.The lactate dehydrogenase (LDH) activity in the culture medium was analyzed.Results AI and LDH activity were significantly higher in HG group than in NG group,and in HG + A/R group than in HG group.Compared with HG + A/R group,AI and LDH activity were significantly decreased in HG + A/R + CGRP group,while no significant changes were found in HG + A/R + CGRP + CGRP8-37 group.Compared with HG + A/R + CGRP group,AI and LDH activity were significantly increased in HG + A/R + CGRP + CGRP8-37 group.Conclusion CGRP attenuates A/R-induced injury to neonatal rat cardiomyocytes incubated in high glucose medium via combing with CGRP receptor.

Objective To investigate the effects of substance P on anoxia/reoxygenation (A/R) injury to cardiomyocytes of neonatal rats.Methods Cardiomyocytes of neonatal rats were isolated from Sprague-Dawley rats,aged 1-3 days,and were cultured in 6-well plates for 72 h.The cardiomyocytes were then assigned into 4 groups (n =3 each) using a random number table:control group (group C),A/R group,substance P group (group SP) and substance P + D-SP group (group SP + D-SP).The cells were cultured routinely for 6 h in group C and the cells were exposed to 99.9 ％ N2 in an incubator at 37 ℃ for 3 h followed by reoxygenation for 2 h in the other groups.The cells were incubated with substance P with the final concentration of 10-7 mol/L for 1 h before anoxia in group SP.The cells were incubated for 1 h with substance P with the final concentration of 10-7 mol/L and D-SP (a specific antagonist of neurokinin-1 receptor) with the final concentration of 10-6 mol/L before anoxia in group SP + D-SP.The apoptosis rate and lactate dehydrogenase (LDH) activity were detected at the end of reoxygenation using TUNEL assay and LDH assay kit,respectively.Results Compared with C group,the apoptosis rate and LDH activity were significantly increased in A/R,SP and SP+ D-SP groups.Compared with A/R group,the apoptosis rate and LDH activity were significantly decreased in SP and SP + D-SP groups.Compared with SP group,the apoptosis rate and LDH activity were significantly increased in SP + D-SP group.Conclusion Substance P can attenuate A/R injury to cardiomyocytes of neonatal rats,and activation of neurokinin 1 receptors is involved in the mechanism.

Conclusion Spinal decompression system could improve the therapeutic effect on lumbar disc herniation.

Objective In this study,we aim to investigate and evaluate the application of peer education on the teaching of medical graduate students and to evaluate the teaching effect,in order to provide the basis for subsequent practice reform.Methods 49 graduate students majoring Internal Medicine-Pulmonology were randomly divided into traditional teaching(24) and peer education groups (25).We chose the primary culture technology of rat distal pulmonary arterial smooth muscle cells to be the teaching contents.For the traditional teaching group,we used the mode of class lecture giving and experimental skills learning under the assistance of the teachers; while in the peer education group,students benefited from the combination of class lecture given by the teacher and the seniors fixed teaching in which seniors help younger students.We selected the experimental operating time,cell purity and the practicing time to reach a standard culture as the evaluation indexes by filling a follow up questionnaire.The SPSS 13.0 was applied to the related data forx2 or t test.Results In the traditional teaching group,the average time to reach three times of standard culture was(3.2 ± 0.5) hour,which was(2.3 ± 0.4) hour in the peer education group.The cell purity was 80.1 ± 3.6％ in the traditional teaching group,while(85.4 ± 5.9)％ in the peer education group.The average practicing time was(6.3 ± 1.0) in the traditional teaching group,while(4.9 ± 0.6) in the peer education group.The peer education group master the teaching content better than the traditional teaching group (P=0.00).95.8％(23/24)of the students in the peer-education group considered the teaching contents simple,which was statistically higher(P=0.00) than traditional group (62.5％,15/24).Meanwhile,95.8％ (23/24)of the students in the peer-education group considered the teaching methods easy to accept,which was also statistically higher(P=0.02) than traditional group(70.8％,17/24).The difference was statistically significant (P=0.02).Conclusion The application effect of peer education is good and there is high degree of acceptance among the students.Besides,peer education accords with the medical postgraduate experiment teaching rules,and can cultivate medical graduate students' spirit of cooperation and communication ability in the process of implementation.

Objective: To clone cDNA of human interleukin-29(IL-29) and express it in cos-7 cells, and to study its anti-HBV activity in vitro. Methods: Total RNA was extracted from PBMCs which had been infected with vesicular stomatitis virus(VSV) in vitro.IL-29 cDNA was amplified using one-step RT-PCR technique. The recombinant expressing plasimd of psectagB/His-myc-IL29 was constructed by inserting IL-29 cDNA into the vector and was then transfected into cos-7 cells. Stable expression stains were screened by Hygromycin B and limited dilution method. The target protein was purified through Ni2+-chelating Sepharose Fast Flow. Anti-viral bioactivity of the recombinant IL-29 fusion protein was analyzed through an in vitro model of production of HBV by the HepG2.2.2.15 cell line.ELISA was used for detection of the viral titers in the cell cultural supernants. Results: IL-29 was cloned and stably expressed in cos-7 cells successfully. SDS-PAGE and Western blot analysis showed multiple bands of the target protein with the molecular weights between 20 000 and 33 000, and the major band was located at about 33 000, indicating the fused IL-29 modified by additional glycosylation. The rhIL-29 was shown to dose-dependently inhibit secretion of HBsAg and HBeAg accompanied by the reduction of HBV genomic DNA in the cells tested. The inhibition ratio of HBsAg and HBeAg production was attained 85% at a concentration of 160 ?g/L of rhIL-29. Conclusion: The rhIL-29 with anti-HBV activity has been obtained.

Objective To analyse the clinical practicability and significance of fertility-sparing surgery for women with recurrent borderline ovarian tumors ( BOT).Methods The clinical and pathological recordings of 12 patients suffered from recurrent BOT in the Obstetrics and Gynecology Hospital of Fudan University from Jan.2002 to Dec.2012 were analyzed retrospectively.The menstruation situation , fertility function , recurrence rate and survival after second conservative surgery were collected and analyzed .Results The average onset age of these 12 patients was 26 years, and none of them had procreation before the second operation.The pathological diagnosis were still BOT and the recurrent sites of 10 patients were still restricted to the ovaries.Of the 12 cases, 8 cases of them had normal menstruation functions and 4 cases had less menstrual volumes or longer menstrual periods.Among 6 cases desired for pregnancy after the second operation,4 cases of them were successful.The spontaneous pregnancy rate was 4/6.The mean duration of follow-up was 53 months(range:23-97 months).All recurrent BOT, three cases developed recurrence once more,two cases of them were just be hinted by B ultrasounds and only one cases was approved to be BOT again by a once more surgical pathology.But no disease related deaths occurred.Conclusions The second fertility-sparing surgery may be feasible for women with recurrent BOT who are young and strongly desired for preservation of fertility.The spontaneous pregnancy rate is satisfactory.However, carefully follow-up is still needed.

A 56-year-old man with 1-year history of palpitation, heat intolerance and sweating, was diagnosed as thyrotropin (TSH) -secreting pituitary adenoma based on the symptoms of hypermetabolism, enlarged thyroid gland, inappropriately increased serum TSH concomitantly elevated plasma thyroid hormones and a pituitary tumor demonstrated on magnetic resonance imaging. Long-acting octreotide formulation was administered at a dose of 20 mg intramuscularly. Tumor volume shrinkage and improvement of thyroid function was achieved after a single drug injection; and the thyroid function returned to normal in 28 days. It is suggested that long-acting octreotide formulation might be used as a routine therapeutic approach prior to pituitary surgery, which may enhance the effectiveness of surgery and postoperative recovery.
