IFI16 plays a critical role in avian reovirus induced cellular immunosuppression and suppresses virus replication.

Avian reovirus (ARV), which commonly induces viral arthritis or tenosynovitis and immunosuppression in chickens, is associated with the nonstructural protein p17 that plays a crucial role in viral replication and regulates cellular signaling pathways through its interaction with cellular proteins. In our previous study, we identified the host protein IFN-γ-inducible protein-16 (IFI16) as an interacting partner of ARV p17 through yeast two-hybrid screening. In the current study, we further confirmed the interaction between IFI16 and p17 protein using coimmunoprecipitation, glutathione S-transferase (GST)-pulldown assay, and laser confocal microscopy techniques. Additionally, we found that the amino acid of p1761-119 is responsible for mediating the interaction with the HINa and HINb domains of IFI16. Interestingly, we observed a significant increase in IFI16 expression upon ARV infection or p17 protein exposure. Moreover, the replication of ARV was found to be largely influenced by the quantity of IFI16 protein. Overexpression of IFI16 led to a significant decrease in ARV replication, while knockdown of the IFI16 expression led to the contrary result. Additionally, our findings demonstrate that IFI16 plays a crucial role in the induction of inflammatory cytokines IFN-ß and IL-1ß during ARV infection as confirmed by qRT-PCR and ELISA analyses. In conclusion, our study provides novel insights into the functional role of p17 protein and the pathogenic mechanism underlying ARV infection, particularly its association with inflammatory response. Furthermore, it offers new perspectives for identifying potential therapeutic targets against ARV infection.

Clinical efficacy and safety of 1aparoscopy-assisted distal gastrectomy for gastric cancer / 中国内镜杂志

Objective To evaluate the clinical efficacy and safety of 1aparoscopy-assisted distal gastrectomy (LADG) for patients with advanced gastric cancer. Methods Clinical data of 198 cases with advanced gastric cancer were retrospectively analyzed. Based on the surgical approach, patients were divided into laparotomy group (n = 101) and laparoscopic group (n = 97), and the intraoperative situation, postoperative complications and quality of life were compared. Results There were no statistical differences in operation time [(226.30 ± 36.40) vs (220.50 ± 29.90) min, t = 1.23, P = 0.221)], number of lymph node cleaning [(22.01 ± 4.99) vs (20.69 ± 4.53), t = 1.95, P = 0.053] between the two groups; the blood loss of laparoscopy group was less than the laparotomy group [(114.50 ± 20.30) vs (168.30 ± 40.04) ml, t = 11.77, P = 0.000]; gastrointestinal function recovery time of laparoscopy group was less than laparotomy group [(72.30 ± 7.91) vs (84.05 ± 9.04) h, t = 9.72, P = 0.000); hospital stay of laparoscopy group was less than the laparotomy group [(8.89 ± 1.57) vs (10.36 ± 2.65) d, t = 4.72, P = 0.000]; there were no statistical differences in the tumor proximal cut end [(5.07 ± 2.04) vs (4.85 ± 1.98) cm, t = 0.77, P = 0.442) and margin of distal [(4.33 ± 1.90) vs (3.90 ± 2.02) cm, t = 1.54, P = 0.125] between the two groups; the postoperative complication rate of laparoscopy group and laparotomy group was 9.27% (9 cases ) and 7.92% (8 cases), respectively, the differencewas not statistically significance (χ2=0.01, P = 0.907); KPS score of laparoscopy group in 7 days after surgery were higher than laparotomy group [(79.33 ± 15.54) vs (73.49 ± 13.37), t = 2.84, P = 0.005], and in 30 days after surgery showed no statistical differences. Conclusion The clinical effect of 1aparoscopy-assisted distal gastrectomy for advanced gastric cancer is equivalent to the laparotomy, while with less trauma. Short-term quality of life in 1aparoscopy group is higher than laparotomy group.

Surgery for 29 cases of extraperitoneal pelvic neoplasms / 国际外科学杂志

Objective To investigate the experience of surgical treatment of primary extraperitoneal pelvic neoplasms,in order to improve tumor resection rate and safety.Methods The clinical data of 29 cases of primary extraperitoneal pelvic neoplasms were retrospectively analyzed from 1995 to 2013.To evaluate tumor resection preoperatively by CT,MRI and three dimensional reconstruction (3 d) medical technology,5 cases of preoperative interventional vascular embolization,intraoperative 2 cases in the iliac artery ligation,2 cases of intraoperative temporary blocking abdominal aorta.Intraoperative combined a variety of surgical approach to remove the tumor.Results Twenty-nine cases of patients,11 underwent tumor resection,5 underwent tumor resection and rectum resection plus sigmoid colostomy,the structure of 4 underwent tumor resection and repair damaged + sigmoid colon rectum temporary colostomy,3 underwent tumor resection and bladder partial nephrectomy,4 underwent tumor resection and uterine ovarian resection,2 underwent tumor resection + tail sacral tumor resection.25 patients recover well after the surgery,complications of 4 cases:intestinal obstruction in 2 cases respectively,pelvic abscess in 1 case,lower limb venous thrombosis in 1 case,cured by conservative and interventional therapy.No operative mortality and incidence of complications was 13.8％ (4/29).Conclusion Pelvic tumor preoperative imaging evaluation,combined incision and multi-visceral resection,fractional resection and recurrence after resection is the effective examination and treatment.
