Objective To measure plasma microRNAs dysregulated in patients with pancreatic cancer and to assess the potential of these miRNAs as biomarkers for pancreatic cancer.Methods Thirty-seven patients with pancreatic cancer who underwent pancreatic resection between June 2010 to July 2011 were enrolled in the Lihuili Hospital,and ten healthy volunteers were used as control in this study.The expression levels of miR-190,miR-196a,miR-221 and miR-222 were analyzed using quantitative real time polymerase chain reaction (qRT-PCR).U6 was used as an internal control.The relationships between clinicopathoiogic characteristics of pancreatic cancer and microRNA expression levels were analyzed.Results The relative abundances of plasma microRNAs were significantly higher in pancreatic cancer patients than in the control group.The highly expressed plasma miR-190,miR-196a,miR-221,miR-222 levels did not correlate with clinicopathologic characteristics of patients such as sex,age,tumor maximal diameter,and level of serum CA199.The plasma miR-196a levels showed a positive correlation with TNM stage in pancreatic cancer patients.Conclusions The plasma levels ofmiR-190,miR-196a,miR-221 and miR-222 were highly upregulated in pancreatic cancer patients.These microRNAs in plasma may provide a new method in the early diagnosis of pancreatic cancer.

Background and purpose:Gestational trophoblastic neoplasm (GTN) is a spectrum of disease arising from trophoblastic cells, and the majority of patients with GTN have favorable outcome because of the sensi-tivity to chemotherapy. While the cure rate for high-risk patients is still 70% to 80% as a result of drug resistance and disease recurrence. This study aimed to evaluate the clinical characteristics and outcome of patients with high-risk GTN.Methods:The clinical records of patients with high-risk GTN treated in Obstetrics and Gynecology Hospital of Fudan University from Jan. 2003 to Jan. 2013 were analyzed and reviewed retrospectively from the aspect of different treatment.Results:Fifty-one patients with high-risk GTN were admitted to this hospital. Among 51 high-risk GTN patients, 46 patients were evaluated retrospectively and 5 patients were excluded for incomplete treatments. Of the 46 patients with high-risk GTN, 27 patients were treated by chemotherapy alone, 19 patients received chemotherapy and adjuvant surgical therapy. Forty-four patients received EMA-CO (VP-16+Act-D+MTX/VCR+CTX) as a ifrst-line chemotherapy, 81.82% (36/44) had complete remission and 8 patients developed resistance to EMA-CO. EMA-EP (VP-16+Act-D+MTX/VP-16+cisplatin) was used as second-line chemotherapy for the 8 patients resistant to EMA-CO, 6 patients (2 underwent adjuvant surgical therapy) achieved remission and 2 patients died as a result of drug-resistance and disease progression. For the remaining 2 patients, one was treated by 5-FU+KSM and pulmonary resection, and the other was treated by MTX for misdiagnosis as ectopic pregnancy and then converted to EMA-CO for the pathological diagnosis of choriocarcinoma after surgery. Both of them achieved complete remission. Ultimately, 95.65% (44/46)patients achieved complete remission. Among the 19 patients who underwent adjuvant surgical therapy, 94.70% (18/19) patients achieved complete remission after chemotherapy and adjuvant surgery, and the remaining one patient died of disease progression.Conclusion:Standard combination chemotherapy is crucial in the treatment of high-risk GTN. The role of adjuvant surgery in the management of high-risk GTN should not be underestimated.

With the continuous development of bone tissue engineering, a variety of emerging bone graft materials provided various methods for repairing bone defects. Early and rapid accomplishment of revascularization of materials interior after implantation of bone transplantation materials is a difficulty faced to bone tissue engineering. Blood vessels ingrowth provides the requisite netritional support for the regeneration reconstruction of bone tissue, for this reason, vascularization plays a significant role in bone tissue engineering. However,there is not a golden standard strategy of vascularization at present. Scaffold materials, cells and growth factors still are three indispensable elements in tissue engineering, and are cardinal points of the promoting vascularization strategies. Multiple growth factors or multiple cells combined with scaffolds, which are hot spots, have obtained excellent vascularization. This review focused on the comprehensive strategies for promoting the successful vascularization of tissue engineered scaffolds.

The international prognostic index (IPI) has been established as one of the best predictors of outcome, and several different immunologic subtypes have been established as independent predictors of diffuse large B-cell lymphoma (DLBCL). This study was aimed to reassess and re-evaluate the useful value of these prognostic predictors in patients treated with immunochemotherapy. A retrospective analysis of clinical records of immuno-chemotherapeutic (rituximab + CHOP, R-CHOP) and route chemotherapeutic (CHOP) groups was carried out. Standard two-step method of immunohistochemical staining was used to assess the expression of CD10, MUM-1, BCL-6 and BCL-2. The different classification models (Han's algorithm and Muris model) were performed for patients with DLBCL according to the immunohistochemical staining results in both R-CHOP and CHOP regimen groups. Then the data of remission and overall survival rate in different groups were analyzed to investigate the effect of these prognostic factors. Total 126 de novo DLBCL patients were collected in this study, including 51 patients with treatment of R-CHOP and the other 75 patients with treatment of CHOP. The results showed that the R-CHOP group had higher complete remission rate (68.8) than CHOP group (58.7). The patients with IPI score ≤ 2 had significantly higher overall response rate and overall survival rates than the patients with IPI scores > 2 in both groups. The survival rates of different subtypes in Han's and Muris models were not different from each other in R-CHOP group, but were obvious different from each other in CHOP group. It is concluded that IPI is still effective and predictive for identification of different risk groups. Immunochemotherapy can improve the remission and overall survival rate of DLBCL, but weaken the effect of outcome predictor.

Objective To analyse the effects of serum estradiol levels during controlled ovarian hyperstimulation (COH) on the outcomes of in vitro fertilization and embryo transfer (IVF-ET). Methods The clinical data of 472 patients undergoing IVF-ET with GnRH analogues recombinant FSH long protocol were retrospectively analysed. The area under the curve (AUC) of estradiol (E2) level was calculated during COH, and patients were categorized into groups according to the percentile of AUC of E2(AUCE2) during COH. The general characteristics and parameters related to the outcomes of IVF-ET were compared among groups. Results The 10th percentile and 90th percentile of AUCE2 were 3 347.0 pmoL/L and 14 414.3 pmol/L, respectively. Four hundred and seventy-two patients were divided into lower reaction group (AUCE2 3 347.0 pmol/L, n=48), normal reaction group (14 414.3 pmol/L>AUCE2 > 3 347.0 pmol/L, n=376) and higher reaction group (AUCE2≥14 413.3 pmol/L, n=48). There was no significant difference in age, body mass index, baseline follicle stimulating hormone level, time of treatment with gonadotropin, endometrium thickness on day of transfer and embryos transferred(P>0.05). Compared with lower reaction group and normal reaction group, the number of oocytes per retrieval and number of embryos frozen were significantly larger(P<0.01) and the mild/severe ovarian hyperstimulation syndrome rate was significantly higher in higher reaction group(P<0.05). There was no significant difference in fertilization rate, cumulative embryo score, high-grade embryo rate, clinical pregnancy rate and implantation rate among groups (P> 0.05). Conclusion Sustained snpraphysiological serum E2 levels during the COH process do not adversely affect the quality of oocytes and embryos, clinical pregnancy rate and implantation rate to some extent in IVF-ET.

Traditional Chinese medicine (TCM) has definitely clinical effect in treating hyperlipidemia, but the action mechanism still need to be explored. Based on consulting Chinese Pharmacopoeia (2010), all the lipid-lowering Chinese patent medicines were analyzed by associated rules data mining method to explore high frequency herb pairs. The top three couplet medicines with high support degree were Puerariae Lobatae Radix-Crataegi Fructus, Salviae Miltiorrhizae Radix et Rhizoma-Crataegi Fructus, and Polygoni Multiflori Radix-Crataegi Fructus. The 20 main ingredients were selected from the herb pairs and docked with 3 key hyperlipidemia targets, namely 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase), peroxisome proliferator activated receptor-α (PPAR-α ) and niemann-pick C1 like 1 (NPC1L1) to further discuss the molecular mechanism of the high frequency herb pairs, by using the docking program, LibDock. To construct evaluation rules for the ingredients of herb pairs, the root-mean-square deviation (RMSD) value between computed and initial complexes was first calculated to validate the fitness of LibDock models. Then, the key residues were also confirmed by analyzing the interactions of those 3 proteins and corresponding marketed drugs. The docking results showed that hyperin, puerarin, salvianolic acid A and polydatin can interact with two targets, and the other five compounds may be potent for at least one of the three targets. In this study, the multi-target effect of high frequency herb pairs for lipid-lowering was discussed on the molecular level, which can help further researching new multi-target anti-hyperlipidemia drug.

Objective To investigate DSA- estimated hepatic arterial hemodynamics of hepatocellular carcinoma (HCC) determined shortly after transcatheter arterial chemoembolization (TACE) plus sorafenib treatment. Methods The clinical data of thirty HCC patients treated with TACE were retrospectively analyzed. The patients were divided into study group (n = 13) and control group (n = 17). Patients in the study group received additional oral administration of 400mg sorafenib twice a day one week before or two weeks after TACE procedure, while patients in the control group received TACE only. The initial DSA images as well as the images obtained at three months after TACE were analyzed. With the help of Photoshop software, the grey gradient of the tumor staining was measured on the series dynamic DSA images, based on which the time- density curve of the tumor was drawn. The peak density value (PV), the time to reach the peak (TP) and the slope of the upslope (SU) were determined, and the results were compared between the two groups. Results Photoshop software was used to measure the grey density values of the tumor staining on DSA images. In the study group, the post- treatment PV was smaller than the pre- treatment one, which were (38.0 ± 14.6) and (46.7 ± 18.4) respectively, the difference between the two groups was statistically significant (P = 0.040). The post- treatment PV of the study group was also smaller than that of the post -treatment PV of the control group (54.4 ± 19.8), and the difference between the two was also statistically significant (P = 0.011). No significant differences in TP values and SU values existed between the two groups as well as between the pre - treatment and post - treatment ones in each group. Conclusion After TACE.

This paper is to test the physical precision of SGS-I?-knife treatment system. The total positional precision and?-treatement planning system (?-TPS) planning misdose are tested by film and ionization chamber. The precision of head target location is less than 0.88mm. The body target is less than 1.52mm. The error of single target point between the measured and the predicted doses is less than 0.52% and the error of multi target points is less than 3%. The isodose distribution (on axial plane) from the film is consistent with the predicted one. So, SGS-I?-knife can meet clinical requirements.
