Objective To evaluate popliteal artery local technique in superficial femoral artery antegrade subintimal recanalization.Methods From January 2009 to Dec 2011,550 limbs in 476 TASC (Trans-Atlantic Inter-Society Consensus) Ⅱ C/D cases underwent endo-therapy at our department.The success rate、operation time、symptom progress and follow up were analyzed retrospectively.Results In the 550 limbs,62 limbs received popliteal artery local technique directly.There was 9 technical failures.Procedures succeeded in 53 limbs(85.5％ ).The average operation time was (69 ±24) min,(1.8 ±0.6) stents were used and the main covered length was ( 33 ± 6) cm.Symptoms of 46 limbs was improved and unchanged in 6,amputation needed to be done in one limb.One year follow up accomplished for 39 limb.The 6 and 12 months patence rate was 87.1％ and 69.2％.For 488 limbs using traditional approach 378 achieved anti-grade recanalization,the average operation time was ( 89 ± 30) min,average (2.1 ± 0.6) stents were used and the main covered length is (31 ± 13) cm.Symptom in 300 limbs improved.The half and one year patence rate in 292 limbs was 92.1％ and 61.0％.Conclusions The popliteal artery local technique is as effective as with traditional approach and is time saving.

Objective:To investigate the value of anti-hexokinase1 antibodies (anti-HK-1) and anti-kelch-like 1 antibodies (anti-KLHL12) antibody in evaluating ursodeoxycholic acid (UDCA) response in patients with primary biliary cholangitis (PBC).Methods:112 PBC patients who had been treated with UDCA for more than 12 months with relatively complete clinical data were analyzed. Serum was collected and the expression of anti-mitochondrial antibody (AMA), anti-HK-1 and anti-KLHL12 antibodies were detected by ELISA. The response to UDCA was based on Paris standard. According to the expression of new antibodies, the patients were divided into the new antibody positive group and negative group. In addition, PBC related baseline indicators were collected, and Spearman correlation analysis was used to study the correlation between antibody expression and baseline indicators in PBC patients.Results:Positivity of anti-HK1 and anti-KLHL12 antibody in AMA-positive PBC patients were 44.7% and 41.2% respectively. Positivity of anti-HK1 and anti-KLHL12 antibodies in AMA negative PBC patients were 33.3% and 22.2%. Anti-HK1 positive patients had higher serum levels of Alaninetransaminase (ALP), aspartate aminotransferase, (AST), γ-glutamyl transpeptidase (γ-GT) and total bilirubin (TBIL) compared with anti-HK1 negative patients, with statistical significant differences ( P<0.05). Notably, correlation analysis showed significantly positive correlation between anti-HK1 antibody expression and ALP, γ-GT and TBIL serum levels ( r=0.735, P<0.05; r=0.332, P<0.05; r=0.491, ( r=0.466, P<0.05). The UDCA response rate in anti-HK-1 antibody positive group was lower than that of the negative group (36.2% vs 60%; P<0.05). Conclusion:Anti-HK-1 and anti-KLHL12 antibody can help to diagnose PBC, and the expression of anti-HK-1 antibody is correlated with the severity of PBC, which could help to predict the reaction of PBC patients to UDCA.

AIM: To investigate the possibility of 3T3 fibroblast growth on blood fibrin clot in culture medium with recombinant human basic fibroblast growth factor (rhbFGF). METHOD: Growth of the cells on blood fibrin clot was studied by phase-contrast, scanning and transmission electron microscopy and by Giemsa stain and MTT assay. RESULTS: The optimal concentration of rhbFGF for proliferation and survival of the cells was 100 ng/mL. The cells also grew on blood fibrin clot scaffold in the low-serum medium containing 100 ng/mL rhbFGF, and a greater number of the cells survived after 48 hours incubation compared to that after 24 hours. The elongated filopodia appeared to bridge the gaps among the fibroblasts after 24 hours incubation. Further incubation to 72 hours, a greater number of platycytes were found to be joined together by lamellopodia. CONCLUSION: 3T3 fibroblasts could grow and survive on blood fibrin clot in the low-serum medium containing rhbFGF, and a combination of blood fibrin clot and rhbFGF may have over proportional effects on wound healing.

Objective To explore the effectiveness of using somatosensory evoked potentials (SEPs) combined with event-related potentials (ERPs) to predict the prognosis of comatose patients in neurologic intensive care units (N-ICU).Methods A prospective cohort study was conducted in 53 comatose patients enrolled from the Department of Neurology,Xuanwu Hospital of Capital Medical University from January 2011 to June 2014.Short-latency somatosensory evoked potentials (SLSEP),middle-latency somatosensory evoked potentials (MLSEP),N100,and mismatch negative (MMN) were recorded in these comatose patients in N-ICU within one week after coma onset.All patients were evaluated with Glasgow Outcome Scale (GOS) in 3 months after onset.GOS grades 3 to 5 were considered the good outcome; while GOS grades 1 and 2 were considered poor.SLSEP,MLSEP,N100 and MMN were also recorded in 30 healthy controls.The consistency between SLSEP,MLSEP,N100,MMN,and prognosis,as well as the prognostic authenticity of SLSEP,MLSEP,N100 and MMN were analyzed.Results The amplitude was smaller and the latency became longer in comatose patients,compared with healthy controls.The latency of N20,N60,N100 and MMN in patients with good outcome was (21.73 ±2.91) ms,(68.67 ±7.60) ms,(114.81 ±21.60) ms and (194.10 ±55.31) ms,respectively.And the latency of N20,N60,N100 and MMN in patients with poor outcome was (20.74 ±2.05) ms,(64.20 ±5.29) ms,(109.74 ±21.30) ms and (181.00 ± 50.32) ms,respectively.The consistency between poor outcome and absence of evoked potentials for N20,N60,N100 and MMN was satisfactory (x2 =14.60,10.59,14.46,18.12 respectively,all P ＜ 0.05).When combined SEPs with ERPs,the sensitivity was 85.2％,specificity was 74.2％,and general correct rate was 86.8％,respectively,for good outcome; the sensitivity was 74.2％,specificity was 85.2％,and general correct rate was 86.8％,respectively,for poor outcome.Conclusions The bilateral absence of N20 has a good power for predicting the poor outcome in comatose patients,while the bilateral existence of N60,N100 and MMN has a good power for predicting the good outcome.The combined use of SEPs and ERPs in evaluating and predicting the outcomes in comatose patients is suggested.

Objective To compare the cerebral protective effect of propofol and sevoflurane combined with sufentanil anesthesia in the patients undergoing valvular surgery under cardiopulmonary bypass (CPB).Methods Sixty American Society of Anesthesiologists physical status Ⅱ or Ⅲ patients, aged 60-70 yr, scheduled for elective valvular surgery under CPB, were randomly divided into either propofol-based anesthesia group (group PA) or sevoflurane-based anesthesia group (group SA) , with 30 patients in each group.From induction of anesthesia to the end of surgery, group P received targetcontrolled infusion of propofol 0.5-2.0 μg/ml, and group S continuously inhaled 0.5％-2.5％ sevoflurane.Bispectral index value was maintained at 45-55.Immediately after induction (T0), at the end of surgery (T1) , and at 6, 12 and 24 h after surgery (T2-4) , the superior vena cava was retrogradely cannulated for blood sampling, and the concentrations of plasma S-100β protein and neuron-specific enzyme were determined using enzyme-linked immunosorbent assay.Results Compared with group SA, the plasma S-100β concentrations at T1,2 and neuron-specific enzyme concentrations at T1-3 were significantly decreased in group PA.Conclusion The cerebral protective effect of propofol combined with sufentanil anesthesia is superior to that of sevoflurane combined with sufentanil anesthesia in the patients undergoing valvular surgery under CPB.

Objective To compare the prognosis of sentinel node-positive breast cancer patients forgoing axillary lymph node dissection.Methods A systematic literature search (Medline,Embase,Cochrane Library)ended in April 2014 was performed to identify all eligible articles.Two reviewers independently screened and extracted data.RevMan5 was used for statistical analysis.Results A total of 1026 abstracts were retrieved and 18 clinical controlled studies finally included,the total number of patients were 47 894,7389 had micrometastases in sentinel lymph node,35 217 had macrometastases in sentinel lymph node and 5288 had positive sentinel lymph node regardless of micrometastases or macrometastases.For patients with MIC,the 5-year axillary recurrence rate,5-year disease free survival and 5-year overall survival had no significant difference between patients who only received sentinel lymph node biopsy and patients who received further axillary lymph node dissection,(OR =1.78;95％ CI:0.72-4.39,P=0.21),(OR =0.76,95％CI:0.56-1.04,P=0.08),(OR=0.77,95％CI:0.43-1.40,P=0.39).For patients with MAC,the 5-year axillary recurrence rate had no significant difference between patients who only received sentinel lymph node biopsy and patients who received further axillary lymph node dissection,(OR =1.21;95％ CI:O.76-1.91,P =0.42).For patients with positive sentinel lymph node regardless of micrometastases or macrometastases,the 5-year axillary recurrence rate and 5-year overall survival had no significant difference between patients who only received sentinel lymph node biopsy and patients who received further axillary lymph node dissection,(OR =1.29;95％ CI:0.92-1.80,P =0.14),(OR =0.96,95％ CI:0.64-1.45,P =0.84).Conclusions Among patients with limited positive SLN of breast cancer,patients forgoing ALND compared with ALND did not have obvious affect on long-term survival.
