Objective To evaluate the practical effect of assisted nursing with the concept of enhanced recovery after surgery (ERAS) for patients underwent cholelithiasis surgery, and analyze its impact on postoperative complications and physical rehabilitation. Methods Eighty-four patients underwent cholelithiasis operation in our hospital from August, 2019 to May,2020 were selected as the research objects, and the patients were randomly divided into two groups by random number table. The control group was given routine nursing intervention, while the observation group was given nursing intervention based on ERAS.The postoperative complications incidence and recovery of patients were compared. Results Data showed that the postoperative extubation time, first anal exhaust, defecation time and hospitalization time in the observation group were significantly shorter than those in the control group (P<0.05). The total incidence of complications in the observation group was significantly lower than that in the control group (2.38% vs 14.28%, P<0.05). Conclusions In nursing patients undergoing cholelithiasis surgery, ERAS nursing intervention can effectively prevent the occurrence of a variety of postoperative complications, and can effectively speed up the process of postoperative rehabilitation, which is recommended to popularize.

Results Literature review showed that: solid pseudopapillary tumor of the pancreas is a rare low-grade malignancy tumors, which frequently occurs in young women. This case is a thirty-eight years old female patient who was admitted to the hospital due to abdominal pain. Postoperative pathology confirmed a solid pseudopapillary tumor of the pancreas. Follow-up of 1 year showed no obvious signs of recurrence and metastasis. Conclusion Solid pseudopapillary tumor of the pancreas has no specific clinical manifestations, the diagnosis mainly depends on imaging examination and histopathological results. Surgical resection is the preferred treatment for solid pseudopapillary tumors of the pancreas.

目的 探究小分子化合物逆转素(reversine,Rev)对胆管结扎(BDL)诱导的大鼠胆汁淤积性肝损害、纤维化、上皮细胞-间充质转化以及胆管反应的影响。方法 雄性Lewis大鼠随机分成三组,每组各5只。按照如下处理:BDL组大鼠行2周的胆管结扎;BDL+Rev组行胆管结扎同时给予腹腔注射逆转素;对照采用假手术(Sham)。2周后获取血液和肝组织。血指标检测总白蛋白(TP)、总胆红素(TBIL)、谷丙转氨酶(ALT)、谷草转氨酶(AST)、碱性磷酸酶(ALP)、γ谷氨酰转肽酶(GGT)。H&E染色检测肝组织病理。Azan染色检测组织胶原蛋白。免疫组化检测肝组织α平滑肌肌动蛋白(α-SMA)、结蛋白(Desmin)、波形蛋白(Vimentin)、细胞角蛋白(CK7,CK19)、β-连环蛋白(β-Catenin)以及上皮细胞粘附分子(EpCAM)蛋白的表达情况。结果 胆管结扎导致肝脏合成的总白蛋白量下降,总胆红素(TBIL)、谷草转氨酶(AST)、碱性磷酸酶(ALP)、γ谷氨酰转肽酶(GGT)水平明显上升,逆转素处理使下降的总白蛋白上升,使上升的总胆红素(TBIL)、谷草转氨酶(AST)、碱性磷酸酶(ALP)、γ谷氨酰转肽酶(GGT)水平向正常水平回复。逆转素可以缓解胆汁淤积引起的肝纤维化,表现为下调BDL引起的胶原蛋白和α-SMA蛋白沉积。逆转素可以抑制胆汁淤积引起的上皮细胞-间充质转化表现为逆转素明显降低BDL导致的Desmin和Vimentin的表达。逆转素可以抑制胆汁淤积引起的胆管反应表现为明显减少CK7和CK19阳性胆管的表达含量。逆转素抑制胆汁淤积引起的胆管反应与调节β-Catenin和EpCAM的表达有关。结论 逆转素可以缓解胆汁淤积引起的大鼠肝损害,具有一定的保护作用。逆转素可以成为一种潜在治疗药物。

Objective To investigate the effect of reversine (REV) on bile duct ligation (BDL) -induced hepatic damage, fibrosis, epithelial-mesenchymal transformation, and ductular reaction in rats. Methods Male Lewis rats were randomly divided into three groups with 5 rats in each group. Bile duct ligation was performed in the BDL group for two weeks. BDL+ REV group was treated with bile duct ligation and intraperitoneal injection of reversine. The control group was Sham operation (Sham). Blood and liver tissue were obtained after 2 weeks. Blood indexes were determined for total albumin, total bilirubin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and γ-glutamyl transpeptidase. Hepatic histopathology was detected by H&E staining. Azan staining was used to detect tissue collagen deposition. Immunohistochemistry was used to detect the expression of α-SMA, desmin, vimentin, cytokeratin, β-catenin and epithelial cell adhesion molecule (EpCAM) protein. Results Bile duct ligation resulted in the decrease of total albumin synthesis in liver, and the increase of total bilirubin, glutamic-oxalacetic transaminase, alkaline phosphatase and γ-glutamyltranspeptidase. The levels of total bilirubin, aspartate transaminase, alkaline phosphatase and γ-glutamyltranspeptidase returned to the normal level with reversine treatment. Reversine could alleviate cholestasis-induced liver fibrosis by downregulating BDL-induced deposition of collagen and α-SMA protein. Reversine inhibited cholestasis-induced epithelial-mesenchymal transformation by significantly reducing BDL-induced desmin and vimentin expression. Reversine could inhibit cholestasis-induced ductular reaction by significantly reducing the expression of CK7 and CK19 positive biliary cells. Inhibition of cholestasis induced ductular reaction by reversine was associated with regulation of β-catenin and EpCAM expression. Conclusion Reversine can alleviate liver damage caused by cholestasis in rats and have a protective effect. Reversine may be a potential treatment that need further investigation.

Methods A retrospective study of clinical data of a case in our hospital and 71 cases reported in literature with pancreatic schwannoma. Results 72 cases were analysed. The mean age was 54 years (range 17-89 years), with 56 % of patients being female. Mean tumor size was 6.1 cm (range 1-20 cm). Tumor location was the head (29 cases), body and tail (32 cases), and uncinate process (6 cases). 27 cases exhibited solid tumors and 28 cases exhibited cystic tumors. Treatment included pancreaticoduodenectomy (23 cases), distal pancreatectomy (15 cases), enucleation (16 cases). 5 cases (7%) were malignant schwannoma. Tumor size of malignant group was significant larger than benign group (13.8±6.2 cm vs 5.6±4.1 cm,P=0.0004). There was no local recurrence metastasis,or death at the follow-up after operation (range 3-65 months). Conclusion The clinical manifestations of pancreatic schwannoma are lack of specificity and preoperative diagnosis remains difficulty. The tumor size was significantly related to classification of malignant or benign. Pancreatic schwannoma has satisfactory prognosis with surgical treatment.

Objective To explore the effect of bile duct ligation induced obstructive cholestasis on rat hepatocytes. Methods Ten Lewis rats were randomly divided into control group and cholestasis group, and the cholestasis was induced by bile duct ligation for 2 weeks. The histopathological changes were compared by H&E and aniline blue staining and the liver function was compared by biochemical analysis. Primary hepatocytes were isolated by modified two-step collagenase perfusion, and the expressions of hepatocyte marker genes, cell proliferation marker genes and cholangiocyte marker genes were detected by RT-qPCR. Results Compared with the control group,the liver of the cholestatic group showed obvious disordered histopathology, deposition of fibrous collagen and impaired liver function. Compared with the control group, the primary hepatocytes in the cholestasis group expressed higher cell proliferation-related genes（Ki67,Foxm1,Pcna and HGF）（P<0. 05）. Primary hepatocytes in the cholestasis group expressed lower levels of hepatocyte marker genes（Alb,Mrp2,Bsep and Catenin1）（P<0. 05）,and higher levels of cholangiocyte marker genes（Ck7,Ck19,Mdr1 and Cftr）（P<0. 05）and higher levels of the hepatic progenitor cell marker genes（Epcam and Sox9）（P<0. 05）. Conclusions Cholestasis induces rat hepatocyte plasticity in the transformation into bile duct properties.
