The popularization and application of cold storage red blood cells or whole blood at −80 °C of the Rh(D) negative patients in surgical operation

Summary The efficiency of cold storage red blood cells (CSRBC) or whole blood at −80 °C used in 27 Rh(D) negative patients during surgical operation was reported. The Rh(D) negative patients received the transfusion of CSRBC or whole blood stored at −80 °C for 180 to 360 days. The changes in the indexes, such as blood TB, DB, K⁺, Na⁺, BUN, Cr, urine protein (URPO), UOB, Hb, HCT, serum total protein, relative to hemolytic reaction and blood volume before and after transfusion were observed. The results showed that after transfusion of CSRBC or whole blood 27 cases were negative for urine protein and UOB, and the levels of BUN and Cr were normal (P>0.05). Blood TB, DB, Hb, and HCT were increased, while pH, blood K⁺ and blood Na⁺ was normal with the difference being not significant before and after operation (P>0.05). Plasma protein was decreased, but there was no significant difference before and after operation (P>0.05). It was suggested that CSRBC or whole blood at −80 °C could be safely infused to the Rh(D) negative patients without side effects during the surgical operation.

血管重塑对大鼠血管成形术后再狭窄的影响

目的：建立大鼠颈动脉再狭窄模型，原位灌注固定取材。评价PTA后血管重塑（VR）的动态变化规律，定量分析血管重塑在血管再狭窄过程中的变化及作用。方法：制作70只SD雄性大鼠颈总动脉再狭窄模型，分原位灌注实验组、对照组，于术后1h、3、7、14、28和42天原位灌注固定取材，行HE染色、Masson染色，观察标本血管狭窄情况。结果：①血管重塑指数（VRI）在PTA后即刻最大，3天组明显降低，7天组稍有增大，其后不断减小，剩余血管腔面积百分比同VRI的变化曲线基本一致。②FFA后，血管腔面积总体呈逐渐缩小趋势，内弹力板围绕面积（IELA）1h组较对照组明显增大，3天组较1h组明显缩小，14、28、42天组较对照组明显缩小。外弹力板围绕面积（EELA）逐渐缩小。EELA、IELA的变化与血管腔面积变化呈正相关。③VRI与血管腔面积的变化呈正相关，新生内膜面积与剩余狭窄率、血管腔面积无直线相关。结论：再狭窄过程中存在扩张性重塑和收缩性重塑现象，管腔的狭窄与否取决于血管重塑指数的变化，而不是新生内膜的变化，新生内膜的形成是血管重塑过程中的一部分。IELA和EELA可作为判断管腔狭窄及评价血管重塑的指标。

Incidence of Finding Residual Disease for Incidental Gallbladder Carcinoma: Implications for Re-resection

Re-resection for gallbladder carcinoma incidentally discovered after cholecystectomy is routinely advocated. However, the incidence of finding additional disease at the time of re-resection remains poorly defined. Between 1984 and 2006, 115 patients underwent re-resection at six major hepatobiliary centers for gallbladder carcinoma incidentally discovered during cholecystectomy. Data on clinicopathologic factors, operative details, TNM tumor stage, and outcome were collected and analyzed. Data on the incidence and location of residual/additional carcinoma discovered at the time of re-resection were also recorded. On pathologic analysis, T stage was T1 7.8%, T2 67.0%, and T3 25.2%. The median time from cholecystectomy to re-resection was 52 days. At the time of re-resection, hepatic surgery most often consisted of formal segmentectomy (64.9%). Patients underwent lymphadenectomy (LND) (50.5%) or LND + common bile duct resection (43.3%). The median number of lymph nodes harvested was 3 and did not differ between LND alone (n = 3) vs LND + common duct resection (n = 3) (P = 0.35). Pathology from the re-resection specimen noted residual/additional disease in 46.4% of patients. Of those patients staged as T1, T2, or T3, 0, 10.4, and 36.4%, respectively, had residual disease within the liver (P = 0.01). T stage was also associated with the risk of metastasis to locoregional lymph nodes (lymph node metastasis: T1 12.5%; T2 31.3%, T3 45.5%; P = 0.04). Cystic duct margin status predicted residual disease in the common bile duct (negative cystic duct, 4.3% vs positive cystic duct, 42.1%) (P = 0.01). Aggressive re-resection for incidental gallbladder carcinoma is warranted as the majority of patients have residual disease. Although common duct resection does not yield a greater lymph node count, it should be performed at the time of re-resection for patients with positive cystic duct margins because over one-third will have residual disease in the common bile duct.
