The results showed that the method of rubbing the kerf then injection of retrovirus suspension into pancreas could more effectively mark the pancreatic cells than the caudal vein injection and the intraperitoneal injection did in vivo. Furthermore, this study also found that some acinus cells could accept injury stimulus signals to regenerate through resuming mitosis after pancreatic injury.

结果发现在活体条件下，与尾静脉注射及腹腔注射法相比，胰腺伤口涂抹并胰腺内注射反转录病毒的方法能够更有效的标记胰腺细胞；而且，通过对标记细胞的世系追踪研究证明，在胰腺损伤后，胰腺腺泡细胞能够接受损伤信号刺激发生再生。

Also, few centers perform pancreatectomy for nonmalignant disease because of problems with fragile diabetes, especially in alcoholics.

个人评论：单纯就其统计学意义来说，研究人员将接受手术的胰腺癌和慢性胰腺炎患者的死亡率进行了比较，统计表明手术治疗慢性胰腺炎手术死亡率低于胰腺癌患者，但这仍不能作为建议手术治疗慢性胰腺炎的依据，因为没有对慢性胰腺炎患者中手术治疗和非手术治疗患者的预后和死亡率进行对比，我们还无法认定手术治疗慢性胰腺炎效果优于非手术治疗。

Ap with hyperlipaemia model was prepared by both triton wr1339 and cerulein simultaneously. human albumin was used to treat the ap accompanied with hyperlipaemia. in each group, the histological score, volume of ascites, ratio of pancreatic wet/dry weigh, serum amylase and pancreatic acinar cell apoptosis in each group were compared. the level of protein kinase c membrane translocation in pancreatic tissue was detected by western blot.

Results The DNA was obtained from PPJ through a nasopancreatic tube. Aberrant p16 methylation and K- ras gene mutation were detected in the same samples of PPJ. Sensitivity,specificity,positive predictive values,negative predictive values and accuracy of HE staining for pancreatic cancer were 40%,100%,100%,45.4% and 60.0%,respectively. Of the 20 cases of pancreatic cancer,K- ras gene mutation was detected in 14 (70%) and the p16 gene was shown to be methylated in 7 (35%). Of the 8 cases of chronic pancreatitis,K-ras gene mutation was detected in 2 (25%). Of the 2 cases of mucinous cystoadenoma of pancreas,K-ras gene mutation was detected in 1 (50%). Aberrant methylation of p16 was not detected in pancreatic juice samples from patients with chronic pancreatitis and mucinous cystoadenoma of pancreas.

American Atlanta conference edited in September 1992 pancreatitis of serious illness acute definition is: AP companion has local complication (cyst of pancreatic and necrotic, false sex, pancreatic abscess) or the organ fails (function of shock, lung not complete, kidney declines, gastrorrhagia, sow medicinal powder the cruor inside sexual blood-vessel and serious metabolization obstacle), or both holds concurrently.

概要： 急性胰腺炎为临床常见急腹症，是由于胰液和溶蛋白酶漏入到胰腺实质和胰腺四周组织而引起。1963年，法国马赛会议以病理形态学为基础，将AP分为水肿性胰腺炎和出血、坏死性胰腺炎。1992年9月美国亚特兰大会议修订重症急性胰腺炎定义为：AP伴有局部并发症(胰腺坏死、假性囊肿、胰腺脓肿)或器官衰竭(休克、肺功能不全、肾衰、胃出血、播散性血管内凝血和严重的代谢障碍)，或二者兼有。

Result:the incidence of AP went up year by year;(2)bile tract disease is the major reason,but hyperlipdemic AP should be attach importance to for its higher and higher incidence;(3)mean age of biliary AP is higher than alcohlolic and hyperlipdemic AP;(4)the difference of sex is significant in biliary AP and alcohlolic AP;(5)the incidence of local omplications is lower than alcohlolic and hyperlipdemic AP,but the difference is of no significance in view of systemic complications;(6)lungis of the most liability for dysfunction,and renal dysfunction is most closely related to death ;(7)ESS is associated with AP and related to the severity and prognosis .

结果表明：(1)急性胰腺炎发病率呈逐年上升趋势；(2)胆道疾病仍是急性胰腺炎的首要病因，高脂血症性胰腺炎明显增多，应受到重视；(3)胆源性胰腺炎患者年龄高于酒精性和高血脂性等其它原因的胰腺炎；(4)性别差异在胆源性、酒精性胰腺炎中显著；(5)胆源性胰腺炎出现局部并发症几率少于酒精性和高血脂性胰腺炎，而在全身并发症上无明显差异；(6)重症急性胰腺炎中，肺脏最易发生功能障碍，肾功能障碍与死亡关系最密切；(7)急性胰腺炎易伴发正常甲状腺病态综合症，并与其严重程度和预后相关。

The percentage of TGF-β〓 positive cell in the pancreatic cancer tissue (43.8±5.2)％ was significantly higher than that in adjacent pancreatic tissue (28.7±3.6)％, P＜0.05. The worse the cancer cells differentiated and lymphy node metastasis, the more over-expression of TGF-β〓. 2. The percentage of Tr positive cell in the pancreatic cancer tissue (41±4)％ was significantly higher than that in adjacent pancreatic tissue (23±3)％, P＜0.05. The worse the cancer cells differentiated and lymphy node metastasis, the more over-expression of Tr, but the expression of Tr protein was not correlated with lymphy node metastasis (P＞0.05). 3. The percentage of β-GCD positive cell in the pancreatic cancer tissue (62.5± 4.1)％ was significantly higher than that in adjacent pancreatic tissue (33.5±2.8)％, P＜0.05. The worse the cancer cells differentiated and lymphy node metastasis, the more over-expression of β-GCD in pancreatic cancer tissue, but the expression of β-GCD protein was not correlated with lymphy node metastasis. P＞0.05. 4. the expression of β-GCD was significantly correlated with TGF-β〓 and Tr in the pancreatic cancer tissue.
