Objective To explore the value of pathologic diagnosis for pancreatic head mass by using recise Tru-cut biopsy under intraoperative ultrasound guided. Methods Twenty-eight patients with solid pancreatic masses in People’s Hospital of Suqian，Affiliated Hospital Xuzhou Medical College from August 2010 to August 2011 were performed precise Tru-cut biopsy under intraoperative ultrasound guided. In all patients of 28 cases, male 20 cases and female 8 cases, the male-to-female ratio was 5∶2. The patients’ age was 34-78 years old（mean age： 64 years old）. Twenty-eight patients were divided into three groups based upon the greatest dimension of the masses as follows：equal or less than 1.5 cm （group S, 5 cases）, 1.5-3.0cm （group M, 7 cases）, and greater than 3.0cm （group L, 16 cases）. Three needlepasses in each mass were performed. The results of postoperative pathologic findings were compared with specimens in paraffin sections. Results In all cases of 28, the diagnostic coincidence rate was 100%, there were no false positive finding and false negative. The coincidence ratio for pathological diagnosis of tissues with only 1 strip sample （1/3）, only 2 strip samples （2/3）, and with 3 strip samples （3/3） were 3/5, 2/5, and 0/0, respectivly in S group, 0/0, 5/7, and 2/7, respectivly in M group, and 0/0, 4/16, and 12/16, respectivly in L group. The false negative rate of single strip sample in S group and M group was higher than that in L group （χ2=9.833，P=0.002）. There was false negative finding with master single test in small focus of infection. Conclusion Precise Tru-cut biopsy under intraoperative ultrasound guided is a safe and highly accurate method for pathological diagnosis of patients with solid pancreatic lesions, especially in small lesions，it is worthy of clinical application..
Objective To summarize the progress on diagnosis and treatment of gastric stump cancer. Methods Related literatures in recent 5 years were collected, and the progress on diagnosis and treatment of gastric stump cancer were reviewed. Results The diagnosis of gastric stump cancer mainly depends on endoscopy, mucosal biopsy and other imaging examinations. At present, the main treatment of gastric stump cancer is the total gastrectomy, combined with laparoscopic therapy and endoscopic therapy. On the basis of No.1-No.4 and No.7-No.13 lymph node dissection, the extent of lymph node dissection is enlarged according to the different surgical procedures. Conclusions The main treatment of gastric stump cancer is total gastrectomy, and there are many factors affecting the prognosis, which should be early diagnosis and early treatment. Laparoscopic radical gastrectomy for gastric stump caner provides a more convenient and accurate method for the treatment of gastric stump caner.
Objective To investigate the short-term result of catheter directed thrombolysis (CDT) in treatment of acute deep venous thrombosis (DVT) in lower extremity. Methods A total of 289 cases of acute DVT in lower extremity who got treatment in Nanjing Drum Tower Hospital Group Suqian City People’s Hospital and Xuzhou Central Hospital from March 2013 to December 2014 were enrolled prospectively, and of them, 125 cases of system thrombolysis (ST) group underwent ST, 164 cases of CDT group underwent inferior vena cava filter placement (IVCF)+CDT. Clinical effect was compared between the 2 groups. Results Clinical symptoms of all cases were obviously relieved, and limb swelling was significantly reduced. Of the CDT group, 73 cases presented iliac vein compression syndrome (IVCS), and 43 cases of them underwent the percutaneous transluminal angioplasty and stent implantation. In CDT group, there was 1 case complicated by catheter displacement, 10 cases suffered from puncture site ecchymosis, 3 cases suffered from hematuria. In ST group, there was 1 case suffered from pulmonary embolism (PE), 14 cases suffered from bleeding gums, 22 cases suffered from hematuria, 3 cases suffered from skin and mucosa petechia, and 2 cases suffered from melena (didn’t need transfusion). The morbidity of ST group was higher than that of CDT group (P=0.002). There were 18 cases suffered from recurrence in ST group, 15 cases suffered from recurrence in CDT group, but there was no significant difference in the recurrence rate between the 2 groups (P=0.786). In addition, the dosage of urokinase, thrombolysis time, blood vessel patency score, thigh circumference after treatment, and calf circumference after treatment in ST group were all higher than those of CDT group (P<0.050), but the Villalta score in ST group was lower than that of CDT group (P<0.001). There was no significant difference in hospital stay (P=0.383). Conclusion For acute DVT in lower extremity, CDT has a superior short-term outcome with safety and feasibility.
ObjectiveTo establish human bladder cancer cell line with silenced Fibulin-5 gene and observe the effects and mechanism of Fibulin-5 gene silencing on the proliferation activity and migration of the bladder cancer cells.MethodsThe human bladder cancer cells 5637 were divided into group F5 and group NC, and the cells in group F5 were infected with Fibulin-5 RNA interference (RNAi) lentivirus while the cells in group NC were infected with negative-control virus. Then the expression of Fibulin-5 mRNA was detected by real-time quantitative polymerase chain reaction, the cell proliferation activity was detected by MTT, the migration rate was detected by wound healing method, and the expression levels of proteins in receptor tyrosine kinase (RTK) pathway were detected by PathScan RTK Signaling Antibody Array Kit.ResultsThe Fibulin-5 mRNA expression decreased significantly by Fibulin-5 RNAi lentivirus (0.067±0.013 in group F5 vs. 1.001±0.000 in group NC), and the gene silencing efficiency reached 93.3%, so the Fibulin-5 silencing cell line was established successfully. Comparing with group NC, the relative absorbance value and migration rate of cell 5637 in group F5 decreased significantly (P<0.01); in addition, the expression levels of anaplastic lymphoma kinase, Axl, p44/42 mitogen activated protein kinase, and Src protein were up-regulated in group F5 (P<0.05).ConclusionFibulin-5 may play a role in the proliferation and migration of bladder cancer cells, and may have an inhibitory effect on extracellular signal-regulated kinase and its signaling pathway proteins.
ObjectiveTo explore the application value of damage control in intra-abdominal sepsis. MethodsThe related literatures were searched by searching literatures with " damage control” " damage control resuscitation” damage control surgery”, and " intra-abdominal sepsis”, to made an review. Results Despite significant advances in management and treatment, mortality from intra-abdominal sepsis remained still high. Due to its unique anatomic and microbial environment, initial operation could not completely remove the source of infection and avoid complications. Therefore, it was becoming increasingly popular to utilize a damage control strategy with abbreviated laparotomy and planned reoperations. ConclusionsDamage control is characterized by staged treatment, and is widely accepted used to manage intra-abdominal sepsis.
