50% was seen in 7 cases after TACE and PEI(30%),and the 1?3?5 year′s survival rate was 52%?35%? and 9%,respectively.Conclusions Adjuvant chemotherapy was hardly beneficial to the treatment of liver cancer with parasitic blood supply after TACE, while PEI enhanced effect of TACE as a supplementary therapy as judged by long term survival. The change of sIL-2R, AFP level was a sensitive indicator for the outcome of the treatment.

Objective To explore the microanatomy technique of the endoscopy-assisted extreme lateral supracerebellar infratentorial keyhole approach and clinical significance.Methods The extreme lateral supracerebellar infratentorial keyhole approach was imitated in 10 vascular perfusion adult cadaveric heads fixed in formalin,the dorsolateral mesencephalon region was dissected and observed by microscopy and neuroendoscopy from December 2012 to March 2013.Results The extreme lateral supracerebellar infratentorial keyhole approach could be fully exposed the ambient cisterns,the posteromedial tentorial incisura,the dorsolateral mesencephalon region,the trochlear nerve,the root of the trigeminal nerve,the superior cerebellar artery,the posterior cerebral artery and other important anatomical structures.The temporal lobe and parahippocampal gyrus could be exposed when the tentorial was incised.The application of neuroendoscopy could clearly reveal the trigeminal nerve and surrounding structures.Conclusion The extreme lateral supracerebellar infratentorial keyhole approach is suitable for the surgical resection in dorsolateral mesencephalon region.The application of neuroendoscopy can make up for the lack of the trigeminal nerve observed under microscopy and expand the operative field.

OBJECTIVE To investigate the correlative factors that would affect the prognosis of geriatric lower respiratory infection.METHODS A total of 101 geriatric patients diagnosed as lower respiratory infection were enrolled in emergency ICU.The laboratory tests such as blood chemical tests,C-reactive protein,and troponin T(cTnT)were obtained twice 2 hours and 24 hours after admission,respectively.Other parameters including general condition,clinical outcomes as well as APACHE Ⅱ and SIRS scores within 24 hours were recorded.RESULTS The ages,cTnT and SIRS score were negatively correlated to clinical outcome.CONCLUSIONS The ages,SIRS scores and cTNT levels are independent prognostic factors in geriatric lower respiratory infection.

Objective To probe the effect of perioperative therapeutic regime on breast reconstruction after surgery in breast cancer patients.Methods We retrospectively reviewed the clinical data of 145 consecutive breast cancer patients with 162 reconstructions.Results 127 of 145 patients got an excellent or good appearance (87.6%),and 42 cases had complications occurring in 162 operations (25.9%).After a median follow-up of 38.4 months,recurrences were found in 9 patients,3 cases died,and the disease free survival rate was 93.1%.Multivariate analysis showed that radiation therapy,without nipple-sparing and one-stage prosthesis implant were independent risk factors for negative postoperative aesthetic outcome;Delayed reconstruction and implant reconstruction were found to be protective factors for the postoperative complications.Conclusions Although the survival rate appears to be scarcely affected,different treatment modalities in reconstruction strategy bring different clinical results and outcomes.The perioperative decision-making of reconstruction strategy should be based on oncological safety,postoperative complications,aesthetic outcomes and subsequent therapies.

Objective:To determine the therapeutic effects of hepatic radioembolization with phosphorus 32 glass microsphere( 32 P GMS) in the treatment of hepatocellular carcinoma(HCC).Methods:21 cases of HCC had received the hepatic radioembolization by 32 P GMS.Results:The blood flow in the hepatic artery of tumor area reduced remarkably,even nearly disappeared,the size of tumor was smaller after the hepatic artery administration with 32 P GMS.The survival rate of 6,12,and 18 months was 85.7%,61.9%,57.1% respectively.Conclusion:The Intraradioembolization is effective therapy for the advanced HCC.

Objective To study the applicable value of resection of segment VIII after cryotherapy for hepatocarcinoma. Methods As for 8 patients with hepatocarcinoma in segment VIII, the turnor was dealt with cryotherapy before resected. Results All the tumors were resected smoothly after cryotherapy with less bleeding (mean 430ml), less time (mean 138min) and without severe complications or postoperative death in this series. Conclusions Resection of segment VIII after cryotherapy for hepatocarcinoma is proved safe and feasible, whitch can decrease blood loss, save time, reduce tissue injury, and decrease postoperative recurrence.

Background and purpose: Factor that binds to the inducer of short transcripts of human immuno-deficiency virus-1 (FBI-1) in a variety of malignant tumors showed high expression levels, which may be closely related to tumor proliferation and differentiation, angiogenesis, metastasis, but its relationship with breast cancer has not been fully elucidated. The purpose of this study was to investigate the expression of FBI-1 in breast cancer cells, and to study the effect of FBI-1 gene expression on the proliferation of breast cancer cells and its possible mechanism. Methods:Real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot analysis were applied to detect FBI-1 expression in normal human mammary epithelial cell line MCF-10A and breast cancer cell MCF-7. RNA interference method was used to down-regulate FBI-1 expression in MCF-7 cells. The cell proliferation was measured by CCK-8 kit and colony formation assay. RTFQ-PCR and Western blot were used to detect the expression of FBI-1 and NF-κBp65 in MCF-7 cells before and after the interference of FBI-1 expression. Results: The expression of FBI-1 was higher in breast cancer cells than that in normal human mammary epithelial cells (P<0.05). The effects of FBI-1 down-regulation inhibited proliferation in MCF-7 cells (P<0.05). At the same time, after inhibition of FBI-1, the NF-κBp65 mRNA and protein expression levels were significantly decreased (P<0.05). Conclusion: FBI-1 is highly expressed in breast cancer cells. Down-regulated FBI-1 expression can inhibit the proliferation of breast cancer cells,and its mechanism may be related to the inhibition of NF-κB signaling pathway.

PurposeTo evaluate the significance of ultrasonic elastography strain ratio, MRI and the combination of both in diagnosis of breast tumor.Materials and MethodsFifty-four cases with single breast tumor underwent preoperative ultrasound elasticity imaging and MRI. Accuracy of ultrasound elastography strain rate ratio (SRR) of the tumor and surrounding normal breast tissue was measured by quantitative ultrasound elastography, and its combination with MRI were analyzed. ResultsThere was signiifcant differences on SRR between the benign group and the malignant group (2.24±1.28vs 4.96±1.73, t=2.648,P<0.05). Optimal threshold of ultrasonic elastography SRR in differential diagnosis of breast benign from malignant tumor was 2.41 determined by ROC curve. The accuracy of SRR, MRI and the combination of both in differentiating benign from malignant breast tumor was 81.48% (44/54), 85.19% (46/54) and 96.30%(52/54), respectively. There was no statistic difference between SRR and MRI in diagnostic accuracy (χ2=0.267,P>0.05). Combined both had higher diagnosis accuracy when compared with SR and MRI separately (χ2=6.000 and 3.967,P<0.05).Conclusion Ultrasonic elastography strain ratio is accurate and objective in differentiating benign from malignant breast tumors. It is a valuable quantitative index in clinical practice. Moreover, SRR combined with MRI can reduce the misdiagnosis rate.
