Journal of Interventional Radiology 2001;0(06):-
Objective To assess the clinical efficacy of interventional management for the treatment of renal artery stenosis. Methods Percutaneous transluminal balloon renal angioplasty and / or percutaneous transluminal renal artery stenting were performed in 47 patients with renal artery stenosis (55 stenosed arteries in total). A follow-up study on the blood pressure and renal function was conducted and the results were statistically analyzed. Results Fifty-four stenosed renal arteries were successfully reopened,of which only percutaneous transluminal balloon angioplasty was adopted in 17 and percutaneous transluminal renal artery stenting in 37. One patient died during the procedure. A follow-up for a mean period of (2.5 ? 0.6) years was carried out. The blood pressure determined at one (n = 46),6 (n = 46),12 (n = 33) and 24 (n = 29) months after the treatment was significantly decreased when compared to that determined before the treatment (P

Journal of Zhejiang Chinese Medical University 2015;(8):643-646
Objective] Introducing the research on acupoints compatibility in recent ten years in order to discuss the research ideas. [Methods]Through retrieval of all medical journals of CNKI from Jan.2004 to Sep.2014,thirty-four articles were selected and analyzed. Summarizing and commenting the progress on compatibility mode, mechanism and action nature aspects.[Results]The research has summarized the characteristics of acupoints compatibility on ancient acupuncture literature and researched the clinical application of classic compatibility, discussed the mechanism of acupoint compatibility on the metabolism of biological molecules, the spectrum of endogenous metabolites and the central mechanism, confirmed the synergic and antagonistic effects of acupiont compatibility. There are some progresses but also deficiencies. [Conclusion]The acupoints compatibility research should change into clinical application, take multi discipline research methods and use different ideas. The relationship between acupoints quantity and effect of compatibility must be a research direction.

Objective:To explore the predictive value of preoperative prognostic nutritional index(PNI) and systemic immune-inflammation index(SII) for local tumor stage in bladder cancer after radical cystectomy(RC).Methods:This study is a retrospective study, collecting information on 195 patients with bladder cancer who underwent RC at the Second Hospital of Tianjin Medical University from April 2011 to October 2019. Extract the patient’s preoperative laboratory examination and calculate the PNI and SII. The calculation formula was PNI=albumin (g/L)+ 5×total lymphocyte count (10 9/L); SII=platelets×neutrophils/lymphocytes . Univariate and multivariate Cox regression analysis were used to analyze whether PNI and SII can be used as predictors of muscular invasive bladder cancer(MIBC) and non-muscular invasive bladder cancer(NMIBC). Continuous variables were expressed as mean±standard deviation ( Mean± SD), and t-test was used for comparison between groups; Chi-square test was used for comparison of categorical variables between groups. Generate receiver operating characteristic curve (ROC), calculate area under the curve (AUC) to judge the predictive ability of PNI and SII scoring indicators. The larger of AUC, the stronger the predictive ability. Univariate and multivariate Cox regression analysis were used to calculate the corresponding odds ratio ( OR) and 95% CI. Results:All patients were males, with a mean age of (67.94±8.97) years. Mean serum albumin was (42.13±4.28) g/L, mean PNI was 51.29±6.09 and mean SII was 661.67±506.22. Univariate Cox regression analysis showed that both PNI and SII had statistical significance for the incidence of MIBC; multivariate Cox regression analysis showed that PNI and SII could not be used as the diagnosis of MIBC and NMIBC. PNI was an independent risk factor for predicting tumor stage (pT<3a and pT≥3a).Conclusion:The low preoperative PNI can be used as an independent factor for predicting poor pathological stage (pT≥3a).

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 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 distinguish residual tumor from inflammation after radiofrequency ablation (RA) for hepatic VX2 carcinoma in rabbits according to the comparative study between CT and pathological findings.Methods CT and pathologic examination were performed in different stages of RFA for rabbits hepatic VX2 models,and their different performances were observed.Results Marginal enhancement band was showed with enhanced CT of both residual tumor and inflammation.Moreover,liver tissues peripheral to enhancement band were in gradual weaken pattern.The enhancement band of inflammation was most obvious on the 2~(nd) day after RFA,but weakened gradually and disappeared two weeks later.Conclusion The residual tumor and inflammation could not be distinguished through enhanced CT scanning within 1 week after RFA.Low intensity lesions with peripheral enhancement 2 weeks after RFA should be recognized as residual tumor.
