Objective To summarize the experience in the diagnosis and treatment of symptomatic splanchnic artery dissection. Methods A total of 21 patients with symptomatic splanchnic artery dissection, who were admitted to the Affiliated First Hospital of China Medical University during the period from June 2006 to March 2014, were included in this study. Combined with the literature, the clinical data, including the diagnosis and treatment, were analyzed. Results Contrast-enhanced abdominal CT and CT angiography revealed superior mesenteric artery dissection in 15 cases, celiac artery dissection in 5 cases and splenic artery dissection in one case. Conservative therapy was employed in 5 patients; among them one was complicated with hepatic artery thrombosis. Of the 16 patients who received endovascular stent placement, additional intestinal resection was performed in 2 and transcatheter thrombolysis treatment in other 2. No procedure-related severe complications occurred in perioperative period. All the patients were followed up for 2-74 months (mean of 19.1 months). In patients who received endovascular stent placement, the abdominal pain and the bloody stool were relieved or disappeared, and no abdominal pain recurred. CT angiography showed that in-stent blood flow was fluent, the stent was in good position, and neither stenosis nor thrombosis was observed. One patient with superior mesenteric artery dissection died of stroke three months after the treatment. Conclusion It is very important to make early diagnosis and to adopt early treatment for symptomatic splanchnic artery dissection. CT angiography can confirm the diagnosis in most cases, but attention should be paid to some atypical manifestations. For the treatment of splanchnic artery dissection, endovascular stent placement is mini-invasive, safe and reliable.

Objective To evaluate the technique and result of endovascular treatment for right subclavian artery stenosis or occlusion.Methods Seventeen patients [13 males,4 females ; (56 ± 11)years old] with right subclavian artery stenosis or occlusion were treated with endovascular surgery which included recanalization,balloon angioplasty and stenting via femoral or brachial artery route.Cerebral protection devices were used in 6 cases to avoid cerebral embolism.Results Sixteen of the seventeen patients acquired successful recanalization in 8 cases with subclavian artery stenosis (100％ technical success rate) and in other 8 cases with subclavian artery occlusion (88.9％ technical success rate).Five cases were treated with balloon angioplasty,and 11 cases were treated with balloon angioplasty combined with stenting.Good patency was seen in the 16 cases immediately after the procedure.The cerebral protection devices prevented all the cases from cerebral embolism and were retrieved suceessfully.Sixteen cases were followed up from 1 to 66 months [mean (24 ± 18) months].Restenosis was found in one case 10 months later and was successfully treated with re-PTA.One case with aortoarteritis died of cerebral infarction 18 months later.No symptom recurrence was found in other cases and ultrasound or CTA of followup showed excellent patency.Conclusions Balloon angioplasty and stenting are safe and effective for the treatment of right subclavian artery occlusion.

Objective To investigate effect and mechanism of Xuebijing administration at various concentrations on ischemia reperfusion injury (IRI) of rabbit limbs.Methods Thirty New Zealand rabbits were divided into control group (n =10),Xuebijing group Ⅰ (n =10) and Xuebijing group Ⅱ(n =10) according to random number table.Rabbit models of IRI in lower extremities were established.Each group received corresponding therapy after reperfusion:rabbits in Xuebijing group Ⅰ were firstly administered 4 ml/kg Xuebijing solution and 6 ml/kg isotonic saline; rabbits in Xuebijing group Ⅱ were administered 2 ml/kg Xuebijing solution and 8 ml/kg isotonic saline; rabbits in control group were simply administered 10 ml/kg isotonic saline.Venous blood samples were collected before reperfusion and at 1 h,2 h,4 h after reperfusion to measure coagulation parameters (APTT,Fib,INR and PT) and biochemical items (ALB,LDH and CK).Results APTT in Xuebijing group Ⅰ presented obvious improvement at 1 h and 4 h after reperfusion as compared with control group (P ＜ 0.01).PT in Xuebijing groups Ⅰ and lⅡ was significantly longer after reperfusion than that before reperfusion (P ＜0.05).Fib level in Xuebijing group Ⅰ was much higher at 4 h after reperfusion than that before reperfusion (P ＜ 0.05).ALB level at 1 hour after reperfusion showed no statistical differences from that before reperfusion in Xuebijing groups Ⅰ and Ⅱ (P ＞ 0.05).LDH and CK levels in Xuebijing group Ⅰ were much lower than those in control group after reperfusion (P ＜ 0.05).Conclusions Xuebijing injection relieves limb IRI,with better effect in Xuebijing group Ⅰ than in Xuebijing group Ⅱ.Therapeutic mechanism may be associated with its involvement in adjusting clotting function and mitigating injury of muscle tissues.

Objective To investigate the effects of magnesium isoglycyrrhizinate on liver regeneration and hepatic function following partial hepatectomy in thioacetamide induced cirrhotic rats.MethodsForty-five cirrhotic Wistar rats undergoing 2/3 hepatectomy were randomly assigned to control group ( Group A), Group B and Group C starting the day of hepatectomy, rats in Group B were injected 60mg per kg body-weight magnesium isoglycyrrhizina daily intraperitoneally until the day of sacrifice. Rats in Group A recevied same dose of sodium chloride. In Group C, magnesium isoglycyrrhizina was administered daily 3 days before hepatectomy until the rats were sacrificed. Liver function, serum HGF, serum PLA2,BrdU labelling index and percentage of intial liver weight on days 1, 2 and 7 post hepatectomy were assessed. ResultsRats in Group A had significantly lower BrdU labelling index and serum HGF level than Group C ( t = 2. 831, P ＜ 0.05; t = 3.427, P ＜ 0.05 ) and a markedly higher level of serum PLA2 than the other groups on day 1 posthepatectomy ( Group B t = 2. 794, P ＜ 0.05; Group C t = 2. 902, P ＜ 0.05 ).Rats in Group A had a lower BrdU labelling index and a more increased level of serum PLA2 than Group B and Group C on day 2 posthepatectomy ( BrdU labelling index: Group B t = 2. 736, P ＜ 0.05; Group C t =3.083, P＜0.05; PLA2: Group B t =2.794, P＜0.05; Group C t =2.902, P＜0.05), but had no significant difference in HGF level with the other two groups. The three groups were similar in ALT, AST,TP and intial liver weight on days 1,2 after operation. On the 7th day posthepatectomy, rats in Group A had a higher level of AST ( Group B t = 4. 508, P ＜ 0.05; Group C t = 2. 967, P ＜ 0.05 ) and a lower level of TP ( Group B t = 2. 838, P ＜ 0.05; Group C t = 2. 743, P ＜ 0.05 ), lower liver weight than the other two groups ( Group B t = 3.316, P ＜ 0.05; Group C t = 4. 093, P ＜ 0.05) but there was no difference between the three groups in BrdU labelling index, HGF and PLA2 level. Rats in Group C had significantly higher BrdU labelling index and serum HGF level than the rats in Group B on day 1 after hepatectomy( t = 2. 831, P ＜0.05; t = 2. 836, P ＜ 0.05 ).ConclusionsMagnesium isoglycyrrhizinate inhibits aminopherase release and enhancing liver regeneration in cirrhotic rats after partial hepatectomy.

Objective To investigate the expression and clinical significance of ABCG2 protein in hepato-cellular carcinoma (HCC). Methods Specimens of HCC were collected at The First Aifiliated Hospital of Sun Yat-sen University from January 2005 to December 2006. The expression of ABCG2 protein in 165 samples of HCC tissue, 25 samples of normal liver tissue and 40 samples of cirrhotic liver tissue was detected using immunohisto-chemistry. The correlation between the expression of ABCG2 protein and clinicopathological characters was then analyzed. Enumeration data, survival rate and the difference between groups were analyzed with a chi-square test, the Kaplan-Meier method and Log-rank test, respectively. Results ABCG2 protein expression was weakly posi-tive in all normal and cirrhotic liver tissues. In HCC tissues, the expression of ABCG2 protein was strongly positive in 66 cases and weakly positive in 99 cases. The expression of ABCG2 protein was related to tumor diameter, tumor number, adjacent organ invasion and TNM stages (χ2 =8. 130, 14. 279, 4. 820, 21. 179, P <0. 05). Kaplan-Meier survival analysis revealed that patients with strongly positive ABCG2 protein had a significantly lower 3-year overall survival (24. 1%) compared with those with weakly positive ABCG2 protein (39. 4%) (χ2 = 15.716, P<0.05). Conclusions The expression level of ABCG2 protein is related to tumor invasiveness, TNM stage and prognosis. ABCG2 has the potential to become a new target for HCC treatment.

Objective To evaluate the relationship between the CCNE1 or RIP2, identified at a single nucleotide poly?morphism, and the risk, clinic stage and pathological grade of bladder cancer. Methods Peripheral venous blood samples were obtained from 176 patients with bladder cancer and 210 controls without cancer. DNA was extracted. Polymerase chain reaction (PCR) method was used to detect CCNE1 (rs8102137) and RIP2 (rs42490) polymorphism. According to the postoper?ative pathological results, patients with bladder cancer were determined the grading and staging. The genotype differences of medium gene and the distribution gene were analyzed and compared in bladder cancer group and control group. The relation?ship of CCNE1 (rs8102137) and RIP2 (rs42490) genotypes and clinical data of patients with bladder cancer was analyzed, and the relationship of them with the genetic susceptibility to bladder cancer was also analyzed. Results The genotype dis?tribution was with good group representative in control group. The frequency of CCNE1(rs8102137) variant allele was signifi?cantly higher in bladder cancer group (40.91%) than that of control group (30.95%,OR=1.54,95%CI:1.02-2.45, P<0.05). The frequency of RIP2 (rs42490) variant allele was significantly higher in bladder cancer group (72.73%) than that of control group (62.38%, OR=1.61, 95%CI:1.04-2.48, P<0.05). There were no significant differences in gene polymorphisms of CC?NE1(rs8102137) and RIP2 (rs42490) between different pathological grades and different clinical stages of bladder cancer. Conclusion The CCNE1 (rs8102137) and RIP2 (rs42490) polymorphism have interaction in occurrence of bladder cancer process. There is higher risk of bladder cancer in individuals carrying mutant alleles than that of individuals carrying wild type.
