Objective To compare the efficacy and safety of perioperative chemotherapy regimens based on docetaxel administered in different cycles for locally advanced gastric cancer(LAGC)and gastroesophageal junction cancer(GEJC)through a network Meta-analysis.Methods PubMed,Embase,Cochrane Library,and Web of Science databases were electronically searched to collect randomized controlled trials(RCTs)evaluating docetaxel-based perioperative regimens for the treatment of LAGC and GEJC from inception to February 28,2025.Two researchers independently screened the literature,extracted relevant data,and assessed the risk of bias in the included studies.Subsequently,a network Meta-analysis was performed using R 4.5.0 software.Results A total of 10 RCTs involving 2,064 patients were included.The results of the network Meta-analysis showed that,compared with three cycles of epirubicin,cyclophosphamide,and fluorouracil(ECF regimen)and four cycles of platinum and fluorouracil(PF regimen),both three-cycle and four-cycle docetaxel,platinum,and fluorouracil(TPF regimen)significantly increased the complete tumor resection rate(R0 resection rate).Compared with surgery alone,the three-cycle TPF regimen significantly improved the R0 resection rate.Additionally,the four-cycle TPF regimen significantly improved 3-year and 5-year progression-free survival(PFS)compared with the two-cycle PF regimen,and significantly improved overall survival(OS)at 3 and 5 years compared with the three-cycle ECF regimen.Compared with surgery alone,the three-cycle TPF regimen also significantly increased the pathological complete response rate(pCR rate).Furthermore,compared with the two-cycle TPF and three-cycle ECF regimens,the four-cycle TPF and PF regimens were associated with a lower risk of surgical complications.Conversely,the two-cycle TPF and three-cycle ECF regimens significantly increased the risk of surgical complications compared with surgery alone.No statistically significant differences were observed in the incidence of grade 3 to 4 adverse events among the treatment regimens(P＞0.05).Based on the surface under the cumulative ranking curve(SUCRA)plot and pairwise comparisons,the three-cycle PF regimen appeared to be the most effective in achieving the highest R0 resection rate,the three-cycle TPF regimen appeared to be the most effective in achieving the highest pCR rate,while the four-cycle TPF regimen was associated with the best outcomes in terms of 3-year and 5-year PFS and OS.Conclusion The four-cycle TPF regimen may be associated with the optimal PFS and OS among perioperative chemotherapy regimens.No statistically significant differences were observed between the four-cycle TPF and the three-cycle PF in terms of R0 resection rate,between the four-cycle TPF and the three-cycle TPF in terms of pCR rate,or between the four-cycle TPF and the other seven regimens included in the study in terms of safety assessment.The four-cycle TPF regimen may represent the optimal perioperative chemotherapy regimen for patients with LAGC and GEJC.

Background: Porcine circovirus type 2 (PCV2) is an important infectious pathogen implicated in porcine circovirus-associated diseases (PCVAD), which has caused significant economic losses in the pig industry worldwide. Objectives: A suitable viral vector-mediated gene transfer platform for the expression of the capsid protein (Cap) is an attractive strategy. Methods: In the present study, a recombinant adeno-associated virus 8 (rAAV8) vector was constructed to encode Cap (Cap-rAAV) in vitro and in vitro after gene transfer. Results: The obtained results showed that Cap could be expressed in HEK293T cells and BABL/c mice. The results of lymphocytes proliferative, as well as immunoglobulin G (IgG) 2a and interferon-γ showed strong cellular immune responses induced by Cap-rAAV. The enzyme-linked immunosorbent assay titers obtained and the IgG1 and interleukin-4 levels showed that humoral immune responses were also induced by Cap-rAAV. Altogether, these results demonstrated that the rAAV8 vaccine Cap-rAAV can induce strong cellular and humoral immune responses, indicating a potential rAAV8 vaccine against PCV2. Conclusions The injection of rAAV8 encoding PCV2 Cap genes into muscle tissue can ensure long-term, continuous, and systemic expression.

Objective To investigate the cognition status and possible ways of patients′ privacy divulgence among medical staffs and patients, and to explore feasible strategies to protect the privacy. Methods A self-designed questionnaire about privacy cognition was used to investigate 92 patients and 59 medical staffs on one day in July 2014. Results The majority of patients had certain cognition of individual privacy;34. 8%, 30. 4% and 28. 3% of the patients thought the test outcomes, history of infection, illness conditions were private issues;63. 0%, 39. 1% and 31. 5% of the patients thought the perineum, pygal and chest were private parts. Medical staffs had significant higher privacy cognition compared with the patients ( P<0. 05);86. 4%, 86. 4% and 78. 0% of the staffs thought the emotional experiences, the history of infection, test outcomes were private issues;100. 0%, 89. 8% and 86. 4% of the staffs thought the perineum, pygal and chest were private parts. The private information of the patients would be divulged during the medical care such as:patient rounds and physical examinations, asking for the history of the illness, nursing, room layout, and talking between the medical staffs. Conclusions The medical staffs should enhance and motivate the concept of privacy among the patients in order to reduce the differences between these two groups and to improve the relationship between doctors and patients.
