Objective To evaluate the surgical effects of laparoscopic pancreaticojejunostomy in pigs and investigate the learning curve. Methods A total of 40 porcine cases of laparoscopic pancreaticojejunostomy were performed by a single surgical team from September 2012 to February 2013.According to the operation sequence, pigs were divided into 4 groups with 10 in each group.For analyzing the efficacy of surgery in different stages, the operation time and efficacy of anastomoses were compared between these groups. Results The operation was finished successfully in all the 40 cases.There were statistical significances in operation time among the four groups.The group Ⅳ had significant shorter time (112.7 ±8.3) min than those in the group Ⅰ [(145.1 ± 16.6) min, q=9.154, P<0.05], the groupⅡ[(133.0 ±8.7) min, q=5.735, P<0.05], and the group Ⅲ[(137.2 ±9.0) min, q=6.922, P<0.05], respectively.There was no difference between the group Ⅱ and the group Ⅰ in operation time (q=3.419, P>0.05), so as to other groups.The results of anastomoses among the four groups were not significantly different (χ2 =0.586,P=0.900). Conclusions Laparoscopic pancreaticojejunostomy in pigs is feasible.The learning curve of the operation is about 30 cases.

Objective To investigate the clinic value of enhanced CT-guided percutaneously transthoracic lung biopsy. Methods A total of 423 patients who underwent CT-guided percutaneously transthoracic lung biopsy were retrospectively analyzed. The percentage of specimen are satisfactory,the rate of sample with pathological findings,the number of cases with complications,the average goes of unsuccessful biopsy and the times of changing puncture point were compared between the enhanced CT group and the plain CT group. Results Compare parameters in patients whose procedure were guided with the enhanced CT group and with plain CT group, the average goes of unsuccessful biopsy, the times of changing puncture point in patients, the percentage of specimen that were satisfactory, the rate of sample with positive pathological findings and the rate that complicated with pneumothorax or hemorrhage show statistical significance.(3.08±1.05 vs 3.75±1.34, 8.52%vs 18.54%,90.13%vs 73.60%, 76.62%vs 63.36%, 15.51%vs 27.53%, 7.76%vs 14.04%, P<0.05). Conclusion In patient whose biopsys were guided by enhanced CT, the percentage of samples that are satisfactory is higher, the incidence of complication is fewer and the sample with pathological finding is higher compared to those in patients whose biopsys were guided by plain CT. Therefore, enhanced CT-guided percutaneous transthoracic biopsy is more valuable than plane CT.

Objective To analyze the risk factors of intracranial infection after neurosurgery and the effect of vancomycin.Methods 28 cases of craniotomy in this study, The First Hospital of Ningbo City from January 2011 to July 2014 during the years after the occurrence of intracranial infection patients as the research object, a retrospective analysis of the age, gender, emergency, basic diseases, mastoid airroom, ventricle drainage, posterior fossa surgery, reoperation and operation time (more than 4h).The clinical data, summarize the risk factors of postoperative intracranial infection in department of neurosurgery and to observe the clinical effect of vancomycin in the treatment of such patients.Result The high risk factors of intracranial infection include: Open mastoid gas room during operation, ireoperation, ventricular drainage and operative time (more than 4h).In 28 cases with intracranial infection after craniotomy, the total effective rate of vancomycin treatment was 100.00%.Conclusion The high risk factors of intracranial infection after operation include open surgery, mastoid room, reoperation, ventricular drainage and longer operation time.Vancomycin is an effective drug in the treatment of intracranial infection in the department of neurosurgery.

Objective To explore the clinical prognostic value of rapid detection for plasma NT-proBNP levels on admission in patients with acute myocardial infarction.Methods 56 patients with AMI were measured plasma NT-proBNP imediately in hospital,and then they were divided into A,B and C group according to NT-proBNP levels (A group:＜ 500ng/L,B group:500-2 000ng/L,C group:＞ 2 000ng/L).The incidence of major adverse cardiac events (MACE including congestive heart failure,malignant arrhythmia,cardiogenic shock and sudden cardiac death) in subjects were observed respectively during hospitalisation and 30 days.Results The three group subjects with different NT-proBNP levels presented different incidence of MACE(A group:1,0;B group:3,1;C group:8,6) at duration of hospital stay,30days (x2 =6.705,P =0.035 ; x2 =7.957,P =0.008).With the NT-proBNP levels rising in AMI paitents,the inciedence of MACE increased.The incidence of MACE in A,B and C group were 6.6％,18.18％ and 73.69％ respectively.Conclusion In AMI patients,plasma NT-proBNP levels could predict early MACE incidence,which has an important value to evaluate the early clinical prognosis.

Objective To analyze the pathogenesis,therapy and outcome of pediatric cases with coagulation disorders (CD).Methods All these 137 patients were diagnosed as CD with the methods of hemoglutination five items and/or disseminated intravascular coagulation indexes.Then activity of specific coagulation factors,morphology of bone marrow,hepatorenal function and some other relative tests were performed to find out the cause of CD or the primary disease.Results Forty-three cases were diagnosed as genetic CD with 29 as hemophilia A,4 as hemophilia B and 10 as Von Willebrand disease;while the other 94 patients as acquired CD with 15 as vitamin K-dependence coagulation factor deficiency,22 as hepatic dysfunction,30 as disseminated intravascular coagulation and 1 as thrombotic thrombocytopenic purpura.Genetic CD was treated with replacement therapy to reduce the complication.There was 1 case in this group died of intracranial hemorrhage.Acquired CD was treated with short-term,specific and necessary replacement therapy on the basis of reasonable treatment of primary diseases.Eleven cases died finally in this cohort with 7 cases as liver failure and the other 4 cases as terminal leukemia or lymphoma.Conclusion Pediatric patients with CD were caused by genetic or acquired diseases.In clinic the reason of CD was mainly acquired.The treatment of genetic CD is the replacement of specific coagulation factor for life-long term.The outcome dependes on the lack of degree.While the therapy for acquired CD aims at the primary disease.The principle of blood transfusion is short-term and the outcome dependes on the therapic effects of primary diseases.

Objective To examine the localization of neurokinin B receptor (NK3)\|like immunoreactivity (\|LI) in the central nervous system of the mouse. Methods An immunohistochemcial staining method was used. Results NK3 receptor\|LI was localized in somatic and dendritic profiles in the most parts and in neuropil in a few regions of the mouse central nervous system. A large number of neurons with NK3\|LI was seen in the anterior olfactory nuclei, accumbens nucleus, septal area, ventral pallidum, pallidum, caudate putamen, nucleus of the stria terminalis, anterior hypothalamic area, tuber cincreum area, lateral hypothalamic area, perifornical nucleus, supraoptic nucleus, arcuate nucleus, mammillar nuclei, substatia nigra, ventral tegmental area, retrorubral area, superior and inferior colliculus, periaqueductal gray, nucleus of the solitary tract, and superficial layers of the medullary and spinal dorsal horns. The superfical layers of the cerebral cortex, piriform cortex, dorsal hippocampus, amygdal complex, reticular formation of the brainstem contained some neurons with NK3 receptor\|LI. In the ventral hippocampus, median and intralaminar nuclei of the thalamus and interpeduncular nuclei, NKR\|LI was localized in neuropil. Conclusion\ Neurons with NK3 receptor\|LI were widely distributed in the central nervous system. It may be involved in many physiological functions in the central nervous system of the mouse.\;[
