ALPPS与采用不同栓塞材料PVE对肝再生及手术切除率影响研究

目的 比较不同栓塞材料的门静脉栓塞术（PVE）与联合肝脏分隔和门静脉结扎的二步肝切除术（ALPPS）对剩余肝体积（FLR）增长速率的影响,比较各组FLR的增长速率,二期手术切除率、术中数据和术后并发症。方法 采用单中心、前瞻性、非随机对照的对比研究。2014年11月至2019年12月,海军军医大学第三附属医院共126例因FLR不足导致无法切除的肝细胞癌（HCC）或肝内胆管癌（ICC）病人,将其分为4组：ALPPS组及分别采用氰基丙烯酸正丁酯（NBCA）、微球、明胶海绵作为栓塞材料的PVE组。主要终点为FLR增长速率和二期手术切除率。结果 各组的手术切除例数及二期手术切除率分别为：ALPPS组38例（99.4%）,NBCA组32例（76.2%）,明胶海绵组20例（60.6%）,微球组10例（83.3%）。ALPPS组、NBCA组、微球组的FLR增长速率分别为15.1 mL/d,10.0 mL/d和 8.5 mL/d,均高于明胶海绵组（3.7 mL/d）。结论 采用NBCA及微球作为栓塞材料的PVE导致FLR增长速率低于ALPPS,两种栓塞材料的PVE二期手术切除率相当。使用NBCA作为栓塞材料的PVE其FLR增长速率高于微球,且这两种栓塞材料的栓塞效果均优于明胶海绵。     

Chemoprotective effect of plant phenolics against anthracycline-induced toxicity on rat cardiomyocytes. Part III. Apigenin, baicalelin, kaempherol, luteolin and quercetin

Flavonoids are found universally in plants and act as free radical scavenging and chelating agents with antiinflammatory, antiischemic, vasodilating and chemoprotective properties. In this study, the antilipoperoxidative and cytoprotective effects of apigenin, baicalein, kaempferol, luteolin and quercetin against doxorubicin-induced oxidative stress were investigated in isolated rat heart cardiac myocytes, mitochondria and microsomes. After preincubation of cardiomyocytes with the test compounds for 1 h the cardiomyocytes were treated with the toxic agent, doxorubicin (100 micro M for 8 h). Cardiomyocyte protection was assessed by extracellular LDH and cellular ADP and ATP production. Cytoprotection was concentration dependent for baicalein > luteolin congruent with apigenin > quercetin > kaempferol. All test compounds had signi fi cantly better protective effects than dexrazoxan, an agent currently used for adjuvant therapy during anthracycline antibiotic therapy. In microsomes/mitochondria the IC(50) values of lipid peroxidation inhibition for quercetin, baicalein, kaempferol, luteolin, and apigenin were 3.1 +/- 0.2/8.2 +/- 0.6, 3.3 +/- 0.3/9.6 +/- 0.5, 3.9 +/- 0.3/10.1 +/- 0.8, 22.9 +/- 1.7/18.2 +/- 0.7, and 338.8 +/- 23.1/73.1 +/- 6.4 mM, respectively. The antilipoperoxidative activity of apigenin differed from its cytoprotective effects, but correlated with the free radical scavenging of 2,2-diphenyl-1-picrylhydrazyl radical and half peak oxidation potential (E(p/2)). Apigenin was the least effective of the flavonoids studied in all models except the cardiomyocyte model where its cardiomyocyte cytoprotective effect was comparable to other compounds.     

Analysis of vaginal recurrences in stage I endometrial adenocarcinoma

OBJECTIVE: To determine the risk of vaginal recurrence in Stage 1 endometrial cancer and treatment morbidity associated with different therapeutic approaches MATERIAL AND METHODS: Between 1995 and 2005, 341 patients with clinical Stage I endometrial cancer were treated at Istanbul Medical Faculty. One hundred and forty-four women were included in this study as the follow-ups and records were complete. The patients with no myometrial invasion received no further therapy following hysterectomy. When there was superficial myometrial invasion postoperative vaginal vault radiation was used, and if deep myometrial invasion was present, external pelvic radiation was given. RESULTS: Overall 5-year survival rate for all patients with Stage I disease was 80%. Nine patients (6.25%) developed recurrent disease, three of whom had vaginal recurrences. All three vaginal recurrences were small and diagnosed at routine follow-up exam within 51 months of primary therapy. CONCLUSION: This selective treatment protocol for patients with Stage I endometrial cancer avoided radiation entirely in 38% of the patients while achieving a very low rate of vaginal recurrence and good overall survival.

Abstract Objective To analyze safety and effect of the conversion therapy for initially unresectable colorectal liver metastases (CLMs) under the guidance of multi-disciplinary team (MDT). Methods The retrospective analysis was conducted for 86 patients with unresectable CLMs received MDT management and arrived conversion therapy successfully from January 2008 to December 2011 in Zhongshan Hospital of Fudan University. The perioperative and survival outcomes??prognostic factors were evaluated. Results During the mean follow-up of 41 months (24-68 months), according to the finding time of liver metastases of 86 patients??recurrence events were 73 patients??and 39 patients died. The 1 year??2 year and 3 year overall survival rate (OS) was 90.6%??75.6% and 65.1% respectively. The median OS time was ??47.5±3.1?? months. The 1 year??2 year and 3 year disease free survival rate (DFS) was 72.1%??48.8% and 31.4% respectively. The median DFS time was ??22.0±2.9?? months. The OS and DFS were no significant difference when compared 86 patients with initially unresectable CLMs successfully arrived conversion therapy with 99 patients with initial resectable CLMs??P >0.05??. The perioperative mortality rate was 1.5%??and operative complication rate was 24.4%. Tumor regression grade and early tumor shrink could predict the prognosis of CLM patients received conversion therapy. Conclusion The conversion therapy under the guidance of MDT mode is safe and effective for unresectable CLMs. The mid-term survival rate is similar with initially resectable CLMs??and long-term survival is expected.

Electrogastrography in patients with Roux-en-Y reconstruction after previous Billroth gastrectomy

BACKGROUND/AIMS: The aim of this prospective study was to characterize gastric myoelectrical activity in patients with Roux-en-Y reconstruction after previous Billroth gastrectomy. METHODOLOGY: Thirteen patients entered the study (6 men and 7 women, aged 35-57). The mean time from Roux-en-Y reconstruction to electrogastrography (EGG) recording was 5 years. Surface cutaneous EGG was recorded using a Digitrapper EGG in the morning both fasting and after a standard solid test meal. All patients assessed their dyspeptic symptoms at the time of EGG in a semi-quantitative subjective scale. RESULTS: EGG was abnormal in all studied patients (but one postprandial recording). Dyspepsia was not meal-related and was not more severe in Helicobacter pylori positive patients. There was a significant negative correlation between time from Roux-en-Y reconstruction to EGG recording and bradygastria percent activity, both fasted and postprandial (r = -0.576; p = 0.0022). There was an inverse trend between severity of dyspepsia and normal slow-wave rhythm percent activity. Older patients tended to have more severe dyspepsia. CONCLUSIONS: The results of this study suggest that abnormal EGG recording is associated with dyspepsia in patients after Roux-en-Y reconstruction.
