Now symptomatic extracranial and intracranial stenting usually uses bare metal stents, but the incidence of restenosis is higher.The studies of drug-eluting stems for the treatment of coronary atherosclerosis have suggested that the incidence of restenosis decreases significantly. Although extracranial and intracranial drug-eluting stem placement appears to be safe,further large,prospective,randomized,controlled trials are needed to demonstrate its safety and effectiveness.

Objective To analyze the efficacy of electric sacral neuromdulation and resiniferatoxin in patients with female overactive bladder.Methods 32 cases with IOAB female patients accepted percutaneous test sitmulation of the electric sacral nerves at S3 ,and treated by intravesical instillation with 100ml of 100nmol/L RTX.The effica- cy of voiding status were evaluated.The improvement of female patients life were evaluated comparing the rating of depression and anxiety.Results There were significant improvements in 32 cases in variables included the number of voiding,volume voided and signs every day and urgent uresis.In the rating of depression and anxiety,the patients improved a litter and still had stimulating symptom in urethra and bladder.Conclusion The treatment of IOAB with single administratoon of electric sacral neuromdulation and resiniferatoxin is effective,and can successfully im- prove the symptom with little side effects.

OBJECTIVETo observe the effect of Yiguan Decoction (YGD) on differentiation of bone marrow mesenchymal stem cells (BMSCs) into hepatocyte-like cells in vitro.

METHODSRat BMSCs were isolated using whole bone marrow adherent method. The properties of BMSCs were identified by analyzing the expression of surface cytokines by flow cytometry. The third passage cells were differentiated into fat cells to identify their features. BMSCs were incubated with hepatocyte growth factor (HGF) plus fibroblast growth factor 4 (FGF4) or YGD containing serum YGD for 21 days. The mRNA expression of alpha-fetoprotein (alphaAFP), albumin (Alb), and hepatocyte nuclear factor 4alpha (HNF4alpha) were detected by real time PCR. Expression of AFP and cytokeratin 18 (CK18) protein was detected by cell immunofluorescence. Glycogen synthesis was observed using periodic acid-Schiff stain (PAS). CK18, Wnt 3alpha, and alphacatenin protein expressions were detected by Western blot.

RESULTSHigh expression of CD90, CD29, and CD44, and low expression of CD34 and CD11b were observed in BMSCs isolated by whole bone mar- row adherent method, and numerous lipid droplets were observed in BMSCs using oil red O staining. Both YGD containing serum and growth factor stimulated the expression levels of Alb, AFP, HNF4alpha mRNA and CK18 protein. The down-regulated expression of Wnt 3alpha and beta-catenin could be detected at 21 days after induction. The synthesized glycogen granule could be seen. Down-regulated Wnt 3alpha and beta-catenin expression could also be observed.

CONCLUSIONYGD could induce the differentiation of rat BMSCs into hepatocyte-like cells, which was related to down-regulating Wnt/beta-catenin signal pathway.

To observe the effect of calycosin on the proliferation and activation of primary hepatic stellate cells (HSCs) in rats, and prove calycosin shows the effects through peroxisome proliferator-activated receptor γ(PPARγ) and farnesoid X receptor (FXR). The results indicated that calycosin could inhibit HSC proliferation and expressions of activation marker smooth muscle actin-α and type I collagen. With the increase in HSC activation time, FXR expression reduced, but with no notable impact from calycosin. Calycosin could up-regulate PPARγ expression and its nuclear transition in a concentration-dependent manner. Its prohibitory effect on HSC activation could be blocked by PPARγ antagonist. In conclusion, calycosin could inhibit HSC activation and proliferation, which may be related with the up-regulation of PPARγ signal pathway.

Objective To evaluate ultrasound-guided methylene blue dyeing for radical liver segmental resection.Methods Liver segmental resection with uhrasound-guide methylene blue dyeing (UMD-SR) was performed in 16 cases, results were compared with 16 conventional liver segmental resection (CSR) retrospectively.Results All the operations under uhrasound-guided methylene blue dyeing were successfully carried out, among them, reverse dyeing was used in cases with segment Ⅳ, Ⅴ, Ⅷ resection.The blood loss in UMD-SR group was much less than CSR group(t =3.011 ,P =0.009) , at the cost of a longer operation time (t =5.423,P =0.000 07).There was no difference in the mortality and morbidity rates between two groups.Tumor recurrence rate was 6.25％ in UMD-SR group and 18.75％ in CSR group (x2 =0.133,P =0.285).Conclusions Ultrasound-guided methylene blue dyeing liver segmental resection can reduce the blood loss during operation, improve the safety of hepatectomy in case of hepatic carcinoma.

Objective To evaluate the concept of artery first and total mesopancreatic excision in radical resection of pancreatic head carcinoma through both anterior and posterior approaches.Method The anterior approach was to identify the superior mesenteric artery (SMA) and the posterior approach to confirm the possibility of negative margin at the origin of SMA,on the posterio-lateral vascular wall of superior mesenteric vein (SMV) and the supposed posterior of the mesopancreas.The resection scope were with the celiac trunk and common hepatic artery as the upper boarder,the SMA as the left boarder,the inferior mesenteric vein (IMA) level as the lower boarder,to achieve a complete mesopancreatic excision,namely the en bloc resection of all the involved nerve,the lymph tissue and vascular tissue along the right side of the axial composed by SMA and celiac trunk.Results Of the 15 patients,11 had radical Whipple procedure,among which 2 had a combining SMV resection and reconstruction.1 case suffered from delayed gastric emptying and 2 cases from bile leakage.There was no mortality.The postoperative pathology reported carcinoma in all 11 cases,with duodenum and low bile duct involved in 4 cases,with the duodenum involved in 6 cases,no surrounding tissue involvement was identified in 1 case.Nerve involvement was found in 7 (7/11),vascular involvement in 10 (10/11),and lymphnode metastasis was (2.5 ± 3.8/12.9 ± 4.9).Conclusions The radical resection of pancreatic head carcinoma using the concept of artery first and the total mesopancreatic excision is helpful for an early evaluation of the possibility of radical resection and guarantees negative margins.
