The present study was performed to investigate the seroprevalence and risk factors for Dirofilaria immitis infection in cats from Liaoning province, northeastern China. From October 2014 to September 2016, sera of 651 cats, including 364 domestic cats and 287 feral cats (332 females and 319 males) were assessed. They were tested for the presence of D. immitis antigen using SNAP Heartworm RT test kit. In this population, the average prevalence was 4.5%. Age and rearing conditions (feral or domestic) were found to be associated with the prevalence of D. immitis. The prevalence was significantly higher in feral cats compared with domestic cats (8.4% vs 1.4%, P < 0.01). There was no significant difference between males and females (4.7% vs 4.2%, P>0.05), but older cats (≥3 years old) showed a statistically higher prevalence compared with younger cats ( < 3 years old) in feral populations (16.8 vs 2.4%, P < 0.01), while the difference between the age groups was not statistically significant in domestic cats (2.4% vs 0.51%, P>0.05), all these results suggest that outdoor exposure time may be one of the most important factors for D. immitis prevalence in cats. Results reveal that D. immitis are prevalence in domestic and feral cats in northeastern China, which indicates that appropriate preventive measures should be taken to decrease the incidence of feline heartworm disease in Liaoning province, northeastern China.

OBJECTIVETo investigate the clinicopathological features and prognosis of patients with gastrointestinal stromal tumor(GIST) after surgery in Shandong Province.

METHODSClinicopathological data of GIST patients undergoing surgery from January 2001 to June 2013 in four university teaching hospitals in Shandong Province were reviewed. Pathology results were rechecked. Patients were followed up. The prognostic factors were evaluated by univariate and multivariate analyses with Log-rank test and Cox proportional hazard model.

RESULTSA total of 1039 GIST cases were enrolled, including 509 males and 530 females, with age from 18 to 87 years(median, 58). Ninety-three patients died of GIST during follow-up. The 1-, 3-, 5-year survival rates were 94.6%, 91.7% and 87.8%, respectively. Patients undergoing R0 resection had a higher 5-year overall survival rate than those undergoing R1 resection(88.8% vs 69.0%, P<0.05). For patients with intermediate risk of recurrence after surgery, the 5-year overall survival rate was 94.4% and 89.2% respectively in imatinib and non-imatinib intervention groups(P>0.05). For patients with high risk of recurrence after surgery, the 5-year overall survival rate was 76.8% and 67.7% respectively(P<0.05). Multivariate analysis revealed that tumor size(P<0.01, RR=1.988, 95%CI:1.497-2.641), mitotic count(P<0.01, RR=2.326, 95%CI:1.686-3.208) and tumor rupture(P<0.01, RR=3.032, 95%CI:1.732-5.308) were independent prognostic factors.

CONCLUSIONSTumor size, mitotic count and tumor rupture affect the prognosis of patients after resection of primary GIST independently. The standard treatment of localized GIST is R0 resection. Adjuvant imatinib therapy can improve overall survival of patients with high risk of recurrence after surgery. The efficacy of imatinib for patients with intermediate risk of recurrence remains to be verified.

Leishmaniasis is a prevalent cause of death and animal morbidity in underdeveloped countries of endemic area. However, there is few vaccine and effective drugs. Antimicrobial peptides are involved in the innate immune response in many organisms and are being developed as novel drugs against parasitic infections. In the present study, we synthesized a 5-amino acid peptide REDLK, which mutated the C-terminus of Pseudomonas exotoxin, to identify its effect on the Leishmania tarentolae. Promastigotes were incubated with different concentration of REDLK peptide, and the viability of parasite was assessed using MTT and Trypan blue dye. Morphologic damage of Leishmania was analyzed by light and electron microscopy. Cellular apoptosis was observed using the annexin V-FITC/PI apoptosis detection kit, mitochondrial membrane potential assay kit and flow cytometry. Our results showed that Leishmania tarentolae was susceptible to REDLK in a dose-dependent manner, disrupt the surface membrane integrity and caused parasite apoptosis. In our study, we demonstrated the leishmanicidal activity of an antimicrobial peptide REDLK from Pseudomonas aeruginosa against Leishmania tarentolae in vitro and present a foundation for further research of anti-leishmanial drugs.

Objective:To investigate the preventive effect of postoperative pancreatic fistula by pedicled omentum wrapping pancreaticojejunostomy in pancreaticoduodenectomy.Methods:The clinical data of 78 patients who underwent pancreaticoduodenectomy in Songjiang Hospital Affiliated to Shanghai Jiao Tong University from September 2017 to August 2020 were retrospectively analyzed. Patients were divided into the modified pancreaticojejunostomy group (conventional approach group, n=43) and the pedicled omentum wrapping pancreaticojejunostomy group (omentum wrapping group, n=35) according to the surgical mode. Postoperative pancreatic fistula, postoperative abdominal bleeding, delayed gastric emptying and postoperative hospital stay were compared between the two groups. Results:Compared with the conventional approach group, the postoperative pancreatic fistula rate in omentum wrapping group was significantly reduced (2.9% vs 18.6%), and the difference was statistically different ( P=0.030); postoperative abdominal bleeding rate(0 vs 4.7%)and the delayed gastric emptying rate were significantly reduced (8.6% vs 25.6%), but both of them were not statistically different ( all P value>0.05); the length of postoperative hospital stay was significantly reduced [(11.3±2.9) days vs (12.8±3.5)days], and the difference was statistically different ( P=0.045). Conclusions:The pedicled omentum wrapping pancreaticojejunostomy was simple and convenient, which can significantly reduce the rate of postoperative pancreatic fistula. It can shorten the time of the length of hospital stay after surgery.
