Objective To know the mastery degree of percutaneous coronary intervention (PCI) preoperative nursing knowledge in nurses who are working in emergency department and cardiac ward. Methods 158 cases of nurses who came from three different class Ⅲ grade hospitals with qualification for emergency PCI surgery of the Guizhou province were surveyed with self-made questionnaire. The survey was conducted in nurses who were working in different departments, and the educational background, age, title, category, the cognitive situation of the PCI preoperative nursing knowledge and necessity of preoperative preparations were investigated in nurses. Results The whole pass rate was 48.10%; high qualification, high education, higher title of nurses for the nursing knowledge of the emergency PCI were better; the emergency PCI preoperative preparations for the necessity of cognitive about nurses were on the low side. Conclusion The cognition of the nursing knowledge and the necessity of emergency PCI in preoperative preparations as whole are on the low level, so specialized training should be strengthened to enhance the ability of specialized nursing.

Objective To design a post-peripheral intervention observation form that uses the timepoint and observation project as the framework of contents,and to evaluated its clinical application effect.Methods Non-concurrent patients were used to make a control study.By using the convenient sampling method,101 patients,who received peripheral interventional therapy during the period from June 1,2014 to December 31,2014,were collected and used as the control group;routine nursing care was adopted and the results were documented.A total of 102 patients,who received peripheral interventional therapy during the period from January 1,2015 to June 30,2015,were used as the intervention group,for whom routine nursing care was carried out and self-designed post-peripheral intervention observation form was employed to record the nursing observation.The results of the two groups were statistically analyzed.After using the form,every month 10 patients,5 visiting physicians and 5 responsible nurses were asked to make an evaluation of nursing quality satisfaction.Results The incidence of main postoperative complications in the intervention group was lower than that in the control group,the chi-square test showed that the difference between the two groups was statistically significant (P＜0.05).The average hospitalization days and the mean medical expense of the intervention group were lower than those of the control group,the chi-square test indicated that the difference between the two groups was statistically significant (P＜0.05).After using this form,the nursing quality satisfaction of patients and visiting physicians was improved,the self-rating satisfaction assessed by responsible nurses was also improved,the chi-square test revealed that the difference between the two groups was statistically significant (P＜0.05).Conclusion All the evaluation indexes of the patients in the intervention group are better than those of the patients in the control group,indicating that this observation form is reasonably designed,meets the specialty characteristics,heightening the dynamic observation for patients after peripheral intervention,strengthens the effectiveness of monitoring postoperative complications,and is helpful for the implementation of the observation after peripheral intervention.Therefore,this observation form is worth promoting use.

Objective To investigate the clinical features,diagnosis and prognosis of solid pseudopapillary tumor of the pancreas(SPTP). Method The clinical data of SPTP cases that underwent surgical resection with a definitive histological diagnosis in Zhong Shan Hospital from 1999 to 2007 were retrospectively analyzed.Result There were 42 SPTP cases undergoing surgery in this period,including 37 females and 5 males:mean age was 37.6 years.Tumors located in the pancreatic head in 18 cases and in the body or tail in 24 cases.The most common symptom was abdominal discomfort(n=20),palpable mass (n=8).Preoperative diagnostic accuracy of MRI and CT were 93%and 31.8%,respectively.Ten cases underwent pancreaticoduodenectomy,20 cases received distal pancreatectomy,3 cases did spleen-preserving distal pancreatectomy.Tumors were simply enucleated in 8 cases.Average diameter of the tumors was 6.1 cm,34 lesions were solid,6 were solid-cystic,2 were cystic.The overall perioperative morbidity was 38.1%,10 cases developed postoperative pancreatic fistula.The mean follow-up time was 38.6 months.Except three cases that were lost to follow-up,all the other cases were alive.Four cases(2 cases had had tumor enucleation,2 had had distal pancreatectomy)developed hepatic metastases on 70、110、41、3 months after first surgery,respectively.A transarterial chemoembolization was employed in three cases,while right hemihepatectomy was performed in one case. Conclusion SPTP is an indolent tumor with low-grade biological aggressiveness.Patients had a favorable outcome after surgical treatment,but enucleation should be avoided.Patients with liver metastasis may benefit from chemoembolization and liver resection.

Objective To promote the diagnostic accuracy of intrapancreatic accessory spleen (IPAS).Methods The clinical data of 10 cases of IPAS admitted in Fudan University Zhongshan Hospital from Apr 2005 to Dec 2013 were retrospectively analyzed.Results There were ten cases of IPAS confirmed pathologically.Only 1 of the ten cases was diagnosed correctly and definitely with IPAS preoperatively.The other 9 cases were misdiagnosed with benign or malignant pancreatic tumors,including nonfunctional neuroendocrine neoplasms in 5 cases,pancreatic neuroendocrine cancers in 3 and pancreatic intraductal adenocarcinoma in one.All the nine misdiagnosed patients has no specific symptoms or laboratory indexes.All the IPASs located in the tail of the pancreas with the mean diameter (1.3 ±0.2) cm(0.8-2.5 cm).7 cases of IPAS show strikingly similar dynamic enhancement to the spleen on the CT scans and/or MRI.Accessory spleen around the splenic hilum was found in five cases.Conclusions Morphological study plays an important role in the diagnosis and IPAS carries parallel dynamic enhancement to the spleen on CT scans and/or MRI.IPAS should be considered as a differential diagnosis while the lesion is no more than 2.5 cm in diameter and when other accessory spleens were shown around the splenic hilum.

Objective To investigate the biological features and treatment of pancreatic adenosquamous carcinoma. Methods A retrospective clinical analysis was conducted in 6 cases of pancreatic adenosquamous carcinoma treated in our hospital from 1995 to 2005. The clinical features, imaging findings, therapy and pathology were analyzed. Results Pancreatic adenosquamous carcinoma was found in 3 men and 3 women with a mean age of 51. 8?10. 8 years. Tumor was located in the head of the pancreas in 4 patients, body in 1 and tail in 1. Three cases received pancreaticoduodenectomy, two did distal pancreatectomy and splenectomy, one underwent palliative operation. The mean size of the tumor was 5. 2 cm ? 4. 1 cm ? 3. 0 cm, pathologically primary tumor and the liver metastasis were mixture of adenocarcinoma and squamous cell carcinoma. Tumor invaded the duodenal wall and common bile duct in 3 cases, portal vein was invaded in 1 case. Neural invasion was present in 4 cases. Lymphatic invasion was found in 3 cases. Postoperative mean survival time was 6. 7 months after the operation with patients finally dying of tumor recurrence and liver metastasis. Conclusions Pancreatic adenosquamous carcinoma is characterized by the mixture of adenomatous and squamous cell element with aggressive biological behavior. The prognosis of this tumor is poor demanding early diagnosis and proper surgical treatment.

Objective To construct MUC1-VNTR DNA vaccine pancreatic cancer. Methods The recombinant gene of VNTR was synthesized and cloned into MCS in the pcDNA3. 1/Myc-his ( + ) A vector. pcDNA3. 1-VNTR/Myc-his( + ) A was injected twice into C57BL/6( H-2b)female mice (V group, n = 15). Mice inoculated with either the empty plasmid vector ( D group, n = 15 ) or 0. 9% NaCl ( NS group, n, = 15) were used as control. Two weeks later, both humoral and cellular immunity of the mice were studied. Results The recombinant plasmid pcDNA3. 1 -VNTR/Myc-his ( + ) A encoded the whole exact translation frame region of the pcDNA3. 1/Myc-his ( + ) A vector and the recombinant gene of human VNTR. The transfected COS7 cells expressed transgene products at 48 hours after transfection. Intramuscular delivery of the recombinant plasmid into C57BL/6 mice resulted in more efficient induction of CTL lysis specific against VNTR polypeptide than the D group and the NS group (P
