Objective To evaluate the optimal surgical approach for huge liver neopiasms in the caudate lobe.Methods Thirty-three patients with huge liver neplasms（≥10cm) underwent caudate lobectomy at a single tertiary referral center between January 2001 and June 2007.The surgical out-comes of pateints who underwent isolated caudate lobectomy or caudate lobectomy combined with partial hepatectomy were compared.Result Fifteen（45.5％）of 33 patients underwent isolated total or partial caudate lobectomy（group A）,whereas 18（54.5％) had total or partial caudate lobectomy cellular carcinoma (HCC) (51.5％),followed by hemangioma(21.2％),intrahepatic cholangiocarcinoma(9.1％),angiomyolipoma(6.1％),hepatic adenoma (3％),focal nodular hyperplasia(3％),colorectal liver metastases(3％)and sarcoma(3％).The median diameter of the tumour was 12.3 (range,10.2-21)cm.Patients in group A had significantly longer operative time (280 minutes vs.170 minutes),longer length of hospital stay (17 days vs.12 days)and more blood loss(1250 ml vs.670 ml) than patients in group B.There was no perioperative death in the 2 groups of pateints.Complication rates in group A and group B were 26.7％ and 16.7％ respectively.There was no disease-related death in patients with benign lesions.The1-,3- and 5-year disease-free survivals of patients with malignant lesions in group A and group B were 25.9％,0％,0％and 74.3％,46.7％,31.2％,respectively.The 1-,3- and 5-year overrall survivals were 68.6％,19.7％,0％ and 100％,66.5％,41.8％,respecively.Conclusion The approach to caudate lobectomy depends on the size and location of the lesion and the liver functional reserve.For patients with sufficient liver functional reserve,caudate lobectomy combined with partial hepatectomy is preferred because it is technically less demanding.For patienls with marginal liver functional reserve,isolated caudate lobectomy is the only viable surgical option.

Objective To study the effect of Acanthopanax senticosus saponins (ASS) on organ blood flow and vascular resistance in anesthetized dogs.Methods The cerebral blood flow(CBF),cerebral vascular resistance(CVR),peripheral blood flow(PBF),peripheral vascular resistance(PVR),blood pressure(SDP and DBP) and heart rate(HR) were measured using the MF-27 electromagnetic flowmeter.Results ASS(15 and 30 mg?kg~(-1) iv perfusion for 60 min) augmented CBF and PBF,decreased CVR and PVR within 180 min and slowed down HR at 60-180 min.In addition,ASS(30 mg?kg~(-1) iv perfusion for 60 min) could obviously reduce SBP and DBP.Conclusion Protective effect of ASS on experimental cerebral ischemia may be related to improving cerebral circulation and increasing cerebral blood supplyment.

Objective To investigate the biophysical properties of mechanosensitive(MS) channels in cultured dorsal root ganglion neurons of neonatal rats. Methods MS channels current of cultured dorsal root ganglion neurons of neonatal rats were recorded using cell-attached and inside-out patch-clamp technique.The biophysical properties such as pressure response relationship,current voltage relationship,channel kinetics and ion selectivity were analyzed.Membrane stretch was achieved by the application of negative pressure(suction) to a patch-clamp electrode. Results One type of MS non-selective cation ion channels in the membrane patches tested in cultured dorsal root ganglion neurons of neonatal rats were recorded. Those channels were activated rapidly when suction was applied, and kept active during sustained application of negative pressure and quickly turned off when the suction was released.The MS channels exhibited a nearly linear current voltage relationship in the balance solution.The outward chord conductance was (96.2?3.6)pS (mV is between +40 mV and +60 mV) and the inward slope conductance was (62.5?0.4)pS (mV is between -60 mV and 0 mV). This kind of channels appeared to be outward rectifier.The average reversal potential was (-2.3?0.8)mV.The channel kinetics analysis indicated that suction could significantly increase the duration of short-openings and long-openings and decrease that of long-closings,with no effects on short-closings. Conclusion The results of this study could serve as a reference to the understanding of electric activity of DRG neurons.
