Objective Hilar cholangiocarcinoma (HC) is invariably fatal without surgical resection. The primary aim of the current study was to determine the safety of variable surgical resections for patient with HC and their survival after surgical resection. In addition, prognostic factor for the overall survival was also evaluated. Methods The study included 59 consecutive patients who were newly diagnosed with HC and underwent surgical resections with curative intend between February 2009 and February 2017. Patients were followed up at 3-6 months intervals after hospital discharge. Postoperative complications and overall survival were determined. Associations of clinicopathologic and surgeon-related factors with overall survival were evaluated through univariate analysis and Cox regression analysis. Results Of patients with Bismuth and Corlette (B & C) type Ⅲ (=19) and Ⅳ (=25) HC lesions, 33 (55.9%) were treated with hilar resection combined with major liver resection (MLR), while the other 11 patients with type Ⅲ and Ⅳ, and those with type Ⅰ (=8) and Ⅱ (=7) HC lesions were treated with hilar resection. The overall surgical mortality was 5.1% and surgical morbidity was 35.6%. There was no statistical difference in the mortality between MLR group and hilar resection group (6.1% 3.8%; =0.703, =0.145). The median follow-up period was 18 months (range, 1-94 months). The 1-, 3-, 5-year survival rate was 59.3%, 36.5%, and 17.7%, respectively. The overall survival after resections was 18 months. In HC patients with B & C type Ⅲ and Ⅳ lesions, the median survival was 23 months for hilar resection with MLR and 8 months for hilar resection alone; the 1-, 3-, 5-year cumulative survival rate was 63.9%, 23.3%, and 15.5%, respectively for hilar resection with MLR, and 11.1%, 0, and 0, respectively for hilar resection alone, with significant differene observed (, 9.902; 95% , 2.636-19.571, =0.001). Four factors were independently associated with overall survival: preoperative serum Ca19-9 (, 7.039; 95% , 2.803-17.678, <0.001), histopathologic grade (, 4.964; 95% , 1.046-23.552, =0.044), surgical margins (=0.031), and AJCC staging (=0.015). Conclusions R0 resection is efficacious in surgical treatment of HC. MLR in combination with caudate lobe resection may increase the chance of R0 resection and improve survival of HC patients with B & C type Ⅲ and Ⅳ lesions. Preoperatively prepared for biliary drainage may ensure the safety of MLR in most HC patients. Novel adjuvant therapies are needed to improve the survival of HC patients with poor prognostic factors.

In this paper, effect and molecular mechanism of sika pilose antler type I collagen(SPC-I) of ROS1728 cell were explored. For the SPC-I provides the theory basis for the treatment of osteoporosis. The adherent method was used to cultivate rat osteosarcoma osteogenesis sample cell line ROS1728. The effect of SPC-I on ROS1728 cells proliferation was tested by CCK-8 method. Runx2, osernix, ALP, Coll-I, OC osteogenesis related genes expression was tested by RT-PCR, and Runx2 protein expression was tested by Western-bolt. Results showed that 5 g•L ⁻¹ SPC-I could inhibit ROS1728 cell proliferation, and significantly promote the expression of ROS1728 cell specific transcription factor Runx2 and osterix mRNA, Runx2 protein and marker gene ALP, Coll-I, OC mRNA expression(P<0.01). 2.5 g•L ⁻¹ and 10 g•L ⁻¹ SPC-I could significantly inhibit the ROS1728 cell proliferation(P<0.01), and inhibit the expression of related genes. In conclusion, 5 g•L ⁻¹ SPC-I could inhibit ROS1728 cell proliferation, obviously enhance ROS1728 cell function, promote ROS1728 cell differentiation, maturation.

<p><b>OBJECTIVE</b>To study the effects of Naoan tablets on brain hemodynamics and cerebral microcirculation of soft membrane.</p><p><b>METHOD</b>Cerebral blood stream flux, resistance of blood vessels, blood pressure and heart rate were used as observation indexes in hemodynamics experiment. Artery caliber and the number of capillaries with recovered blood stream were used as observation indexes in microcirculation experiment.</p><p><b>RESULT</b>Naoan tablets at dose of 0.5 g x kg(-1) and 1.0 g x kg(-1) could enhance cerebral blood stream flux, decrease resistance of blood vessels, and reduce blood pressure. While no effects on heart rate. Naoan tablet at dose of 0.7 g x kg(-1) and 2.1 g x kg(-1) could increase the number of capillaries with recovered blood stream and enlarge the artery caliber of soft membrane in rats.</p><p><b>CONCLUSION</b>Naoan tablets can improve the indexes of hemodynamics and cerebral microcirculation of soft membrane.</p>
