Objective To investigate the incidence of postoperative hepatic metastasis,clinicolpathological characteristics and the prognosis for pancreatic cancer. Methods Totally 83 cases with pancreatic cancer admitted in our hospital during January 2007 to September 2012 was retro?spectively analyzed according to clinicolpathological data. Results Postoperative liver metastasis occurred in 31 cases with a metastatic rate of 37.3%. The size(χ2=9.606;P=0.002),vascular invasion(χ2=4.794,P=0.029)and UICC stage(χ2=5.318,P=0.021)were correlated with he?patic metastasis. Univariate analysis revealed the poor prognosis in pancreatic cancer patient with hepatic metastasis(χ2=9.967,P=0.002). Cox re?gression analysis revealed hepatic metastasis as an independent prognostic factor(P=0.001). Conclusion Pancreatic cancer has a high possibility of hepatic metastasis. Postoperative hepatic metastasis was one of the independent factors for the prognosis of pancreatic cancer. Tumor size,vascular invasion and UICC stages were risk factors for postoperative liver metastasis of pancreatic cancer.

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

Objective To explore the relationship between X - linked spondyloepiphyseal dysplasia tarda (SEDL) gene escaping X chromosome inactivation( XCI) and SEDL phenotype. Methods RT - PCR was performed on total RNA which was isolated from blood samples of patients, female carriers and controls. Patients and female carriers were selected from the pedigree with SEDL caused by the mutation (IVS2 - 2A→C) of the gene. cDNA was analyzed by polyacrylamide gelelectrophoresis(PAGE). Results PAGE data indicateed that female carriers expressed both normal and mutant SEDL mRNA,meaning the SEDL gene escaping XCI. Family investigation showed carrier females in the SEDL pedigree presented no symptoms. Conclusions The SEDL gene escaping X chromosome in-activation is firstly identified from human body. This may explain that carrier females present no symptoms.

Objective:A fingerprint of raw material, extract ed and injections of radix notoginseng has been studied and provides the quality information.Method:Polaris C18-A column was used, with mixtu res of acetonitrile and water as mobile phase in a gradient mode. The wavelength of measurement was 203nm.Result:According to the selected chr omatographic conditions, a good fingerprint of radix notoginseng and its extract , preparation has been described.Conclusion:The method is simp le, accurate with good reproducibility. It may be practical value for the qualit y control of sample for radix notoginseng and its preparation.

Objective To prepare a thrombus-targeted ultrasonic contrast agent and to investigate its targeted ability to fresh blood clots. Methods We first synthesized FITC-KGDS-Palm compound, and then prepared thrombus-targeted microbubbles using "ultrasound & high speed shearing method".Fluorescence labeling thrombus-specific peptides and KGDS,directed at the activated glycoprotein(GP)Ⅱb/Ⅲa receptor of platelets were attached to the surface of lipid microbubbles. The concentration and size of TUCA were measured by Malvern Zeta Sizer Nano-ZS590 and Coulter counter.Immunofluorescence was applied to confirm the conjugation.The conjunct ratio was assessed by flow cytometer (FCM).Results The KGDS-TUCA was straw yellow turbid liquor,and the concentration was 1.5×10~9/mL,and the average size was 1.5 μm. The targeted microbubbles conjugated with the thrombus-specific peptides showed bright green rings by fluorescence microscope.FCM demonstrated that the wavelength of shell of KGDS-TUCA changed greatly,and the conjunct ratio was 90.04%.In vitro study showed KGDS-TUCA remained stable for 48 h at 4 ℃ and target-attached to blood clots and showed good stability.Conclusion The ultrasound & high speed shearing method to prepare TUCA is easy and in favor of purification.KGDS-TUCA has high specific biological activity.The conjunct ratio and stability of KGDS-TUCA are excellent.

Objective To investigate the influence of the lymph node micrometastasis and its clinicopathological features on postoperative disease-free survival rate for patients with gastric cancer.Methods The study included 120 patients with pT1-3NoMo gastric cancer. The relationships between clinicopathological features or carcinoembryonic antigen (CEA) positive expression and postoperative disease-free survival rate were analyzed. Results In clinicopathological factors, multivariate analysis identified CEA positive expression was significantly correlated with tumor diameter (P = 0.011 ),depth of tumor invasion (P= 0.027) and lymphatic vessel invasion (P= 0.001 ) in lymph node positively. The average postoperative follow-up was (53.14 ± 16.75) months. There was statistical correlation between the tumor diameter( P = 0.018 ) or depth of tumor invasion ( P = 0.015 ) and postoperative disease-free survival rate. The disease-free survival rate was 90.91% ( 80/88 ), 86.36% ( 19/22 )and 40.00% (4/10) for the lymph node CEA negative,isolated tumor cells (IT Cs) and micrometastasis,respectively. There was significant difference between micrometastasis and the lymph node CEA negative (P= 0.000) or ITCs (P = 0.009), however, the lymph node CEA negative and ITCs was no significant difference (P = 0.438 ). Lymph node micrometastssis of gastric cancer was detected in 10 patients who should belong to stage pN1,the restage rate was 8.33%(10/120). Conclusions If the patients were found micrometastasis in lymph node with high-risk stage pT1-3NoMo gastric cancer for whom chemotherapy may be recommended,because of its high recurrence and poor prognosis.

Objective To introduce the technique and experience in reconstruction of posterior crueiate ligament-posterolateral comer(PCL-PLC)injuries with only one allograft of Achilles tendon. Methods The instable knees in 12 cases with PCL injury combined with three degree chronic PLC injury were treated with PCL reconstruction under arthroscope and PLC reconstruction through posterolateral arc incision.Single bundle grafts of PCL reconstructions in tibial and femoral tunnels were fixed by resorption screws.Fibular collateral ligament(FCL)and popliteofibular ligament(PFL)were reconstructed with reforming Larson(?)method.All reconstruction grafts only needed one Achilles tendon as donator.Total op- eration time was 130 minutes including 90 minutes of PCL reconstruction and 40 minutes of PLC recon- struction.Gradual weight loading was allowed after six weeks of bracing.Results Follow-up for mean 12 months(5-24 months)indicated that tibial“step off”reduction was 83%(10/12)and posterior drawer test of 0-1~+ 75%(9/12).Dial sign evaluated that normal external rotation angle was 75%(8/12).Nor- real varus stress test at 30?knee flexion accounted for 83%(10/12).Scores of Lysholm,Tegner and HSS were 90.5,5.1 and 84.5,respectively(P<0.01=.Conclusion Synchronized reconstruction of PCL and PLC injuries with only one Achilles tendon can obtain satisfactory clinical result,with less expense and shorter operation time.
