Objective In order to examine the value of the combination of carotid artery ultrasound and Transcrani-al Doppler (TCD) in the evaluation of carotid artery stenosis stenting. Methods Seventy-one carotid stenosis cases con-firmed by digital subtraction angiography (DSA) who had cerebral ischemia symptoms and received stent implantation were reviewed. Carotid artery ultrasound and TCD were adopted to measure the vessel diameter, peak systolic velocity (PSV) of the narrow segment, PSV and pulsatility index (PI) of ipsilateral middle cerebral artery (MCA) before and after the treatment of intravascular stents, and a comparison analysis was made. Results Carotid stent implantation significant-ly improved the inner diameter, PSV of the narrow part, PSV and PI of the MCA on the stenotic side. Inner diameter of the narrow part was 3.13±0.83, 4.77±0.51 and 4.64±0.52 mm at before, one week and one year after the implantation, re-spectively (P<0.05). The PSV of the narrow part was 190.69±113.65, 86.15±30.52 and 90.28±29.79 cm/s at before, one week and one year after the implantation, respectively(P<0.05).PSV of the MCA on the stenotic side was 77.68±14.66, 115.62±22.32 and 108.89±20.29 cm/s at before, one week and one year after the implantation, respectively(P<0.05). PI of the MCA on the stenotic side was 0.81±0.01, 1.07±0.01 and 1.06±0.02 at before, one week and one year after the implantation, respectively (P<0.05). Conclusions The present study demonstrates that the combination of carotid artery ultrasound and TCD can quantitatively detect the vascular structural and hemodynamic improvements following the endo-vascular stenting, indicating that the combination of carotid artery ultrasound and TCD can be used for the accurate as-sessment and follow up of carotid artery stenting treatment.

Objective To investigate the role of Hedgehog pathway in hepatic fibrosis and its association with activation of hepatic stellate cells. Methods Twenty male Spragur-Dawley rats were divided into control and model groups with 10 each. The animal models were induced by injection with CCl4 and fed with fat-rich diet. The rats in both groups were sacrified at the 8 week with 5 each and the liver tissues were removed for HSC-T6 culture. The deposition of collagen fiber in liver was detected with HE and Masson staining. RT-PCR was used to detect the expressions of Sonic hedgehog (Shh), smoothened (Smo), patched (Ptc), Gli-1 and α-smooth muscle action (α-SMA) mRNA in HSC-T6 and liver tissues. The influence of cyclopamine (Cyc) and lipopolysaccharide (LPS) on HSC-T6 proliferation were assayed by MTT. The expressions of Shh, Smo, Ptc, Gli-1 and α-SMA mRNA after intervention with Cyc (100μmol/L) and LPS were measured by real-time PCR. Results A lot of lipo and collagen deposited in liver of model rats. The Shh,Smo,Gli-1 and α-SMA mRNA were highly expressed in model rats than those in control group (2-△△Ct were 20.45±3.31 vs. 1, 12.78 ± 0. 53 vs. 1, 10.88 ± 2.41 vs. 1, 4.91 ± 2. 59 vs. 1, respectively, all P value <0. 05). In vitro Cyc inhibited HSC-T6 proliferation in dose dependant manner (F=636.81, P<0.01). Compared to the control group, the mRNA expressions of Smo, Ptc, Gli-1,α-SMA in HSC-T6 were significantly reduced after Cyc intervention (2△△Ct, were 0. 20±0. 11, 0. 21 ± 0. 08, 0. 28 ± 0. 05,0. 27±0.10,respectively, all P values<0.01). Conclusion The expression of members of Hedgehog pathway are increased in the progress of hepatic fibrosis, which may accelerate the hepatiee fibrosis by activating HSC.

Objective To investigate the application value of clinical typing in the treatment of BuddChiari syndrome (BCS).Methods The retrospective corss-sectional study was adopted.The clinical data of 95 patients with BCS who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2012 to September 2015 were collected.Based on patients' compensation and clinical symptoms,3 clinical typing and 8 subtypes of BCS were proposed,and each subtype was treated with corresponding strategies.Observation indices included (1) the clinical typing of BCS,(2) selection of treatment,(3) treatment effect,(4) follow-up situations.Follow-up using telephone interview and outpatient examination was performed once within 3 months after the first treatment and then once every 6 months up to December 2015 or death,loss to follow-up and experienced decompensation.During follow-up,color Doppler ultrasound and blood bio-chemistry test were performed regularly,and CT angiography was also conducted when necessary.Count data were presented as the case or percentage.The survival rate was calculated using Kaplan-Meier method and the survival curve was drawn.Results (1) BCS clinical typing of 95 patients:4 were detected in type Ⅰ (3 in type Ⅰ a and 1 in type Ⅰ b),7 in typeⅡ (4 in type Ⅱa and 3 in type Ⅱb),and 84 in type Ⅲ(43 in type Ⅲa,4 in type Ⅲb,32 in type Ⅲc,and 5 in type Ⅲd).(2) Selection of treatment in 95 patients:① among the 3 patients with type Ⅰ a,2 of them received inferior vena cava balloon angioplasty while 1 patient had to give up the operation due to failure in opening the occlusion.This patient underwent close observation and follow-up afterwards.② The patient with type Ⅰ b underwent cavity-antrum artificial blood vessel bypass operation due to failure in opening the occlusion.③Among the 4 patients with type Ⅱ a,one of them underwent hepatic vein balloon angioplasty.The other 3 patients underwent close observation and follow-up because of failure in intervention therapy,such as segmental occlusion of hepatic vein or difficulty in finding the hepatic vein.④ Among the 3 patients with type Ⅱ b,due to the history of upper gastrointestinal bleeding,2 patients received modified spleen-lung fixation and intestine-cavity blood vessels bypass,respectively,and 1 patient received intestine-cavity artificial blood vessels bypass due to severe peritoneal effusion.⑤ Among the 43 patients with type Ⅲ a,35 patients underwent inferior vena cava balloon angioplasty due to failure in hepatic vein intervention therapy (6 of them received firstly thrombolysis treatment due to combined thrombosis.Four patients received inferior vena cava and hepatic vein balloon angioplasties.Another 4 patients received close observation and follow-up due to failure in both inferior vena cava and hepatic vein intervention therapy.⑥Among the 4 patients with type Ⅲ b,2 underwent inferior vena cava balloon angioplasty and intestine-cavity artificial blood vessel bypass.The other 2 patients only received modified spleen-lung fixation because of failure in inferior vena cava intervention therapy.⑦ Among the 32 patients with type Ⅲ c,3 underwent inferior vena cava and hepatic vein balloon angioplasties,and 27 patients underwent only inferior vena cava balloon angioplasty due to failure in hepatic vein intervention therapy (7 of them received balloon angioplasty following thrombolysis treatment due to combined thrombosis).On account of failure in both inferior vena cava and hepatic vein intervention therapy,2 patients underwent resection of lesion membranes and cavity-antrum artificial blood vessel bypass,respectively.⑧ Among the 5 patients with type Ⅲ d,1 underwent inferior vena cava balloon angioplasty and intestine-cavity artificial blood vessel bypass,and 4 underwent only modified spleen-lung fixation due to failure ininferior vena cava intervention therapy.(3) Treatment efficacy:of 95 patients,8 received followup observation,and 87 patients recovered to varied extent after interventional therapies and operations,with symptomatic relief of leg edema,ulcer,peritoneal effusion and esophageal varicosity.Eighty-seven patients went through the perioperative period safely,and no death occurred.The incidence of postoperative complications was 10.3％ (9/87).The complications mainly include venous thrombosis in lower limbs during catheter-directed thrombolysis therapy,pleural effusion,pneumatosis,and peritoneal effusion after surgery,all of which were cured after symptomatic treatment.(4) Follow-up results:87 were followed up for 3-42 months with an average time of 19 months.During the follow-up,5 patients (1 in type Ⅰ a and 4 in type Ⅲa) received recanalization surgery because of the reocclusion after the inferior vena cava balloon angioplasty,and no decompensation occurred.However,decompensation was found in 11 patients (disease progression in 4 patients and symptom relapse in 7 patients).The survival rates of patients without decompensation at 0.5,1.0,2.0 and 3.0 years after the first treatment were 96.5％,95.0％,83.4％ and 80.5％,respectively.Conclusion According to patients' compensation and clinical symptoms,clinical typing of BCS and treatment strategiesis are determined,and it will provide a satisfactory clinical efficacy.
