ABSTRACT
Objective:To compare and analyze the efficacy and safety of intraoperative radiotherapy (IORT) combined with conventional therapy (surgery combined with radiochemotherapy) and conventional therapy alone for pancreatic cancer.Methods:Literature review was conducted from PubMed, Cochrane Library, Web of Science, Embase, Chongqing VIP, CNKI, Wanfang Data and China Biomedical Literature Service System (SinoMed). The literatures that met the inclusion criteria were screened and the data were extracted. Meta-analysis was carried out by RevMan 5.4 software.Results:A total of 11 studies consisting of 813 patients were included. According to the combined results, compared with conventional therapy, IORT combined with conventional therapy could improve the overall survival rate of pancreatic cancer ( HR=0.66, 95% CI=0.54-0.81, Z=4.03, P<0.001), and did not increase the treatment-related side effects ( OR=1.00, 95% CI=0.69-1.46, Z=0.01, P=0.99), but failed to bring benefit to the local control rate ( HR=0.56, 95% CI=0.31-1.01, Z=1.93, P=0.05). Conclusions:The overall survival rate in the IORT combined with conventional therapy group is significantly better than that in the conventional therapy group. No significant difference is found in the treatment-related adverse reactions between two groups. IORT combined with conventional therapy is worthy of clinical application.
ABSTRACT
Objective To observe the value of transvaginal color Doppler ultrasound (TVCDU) in the diagnosis of endo-metrial lesions.Methods All 246 patients suspected of endometrial diseases underwent TVCDU and transabdominal ultra-sonography.Ultrasonographic characteristics,especially the uterine endometrial thickness and blood flow distribution were observed,and the results were compared with surgery and pathological results.Results A total of 242 patients were pathologically diagnosed as endometrial diseases.TVCDU diagnosed 232 cases,with the diagnostic accordance rate of 95.87%.Transabdominal ultrasonography diagnosed 182 cases,with the diagnostic accordance rate of 75.21%.TVCDU was superior to transabdominal color Doppler examination (P<0.05).Conclusion TVCDU has high diagnosis accordance rate and can be used as routine examination of endometrial diseases.
ABSTRACT
This paper introduces the Vest-style First-aid Kit which are newly developed for PLA.Adopting a vest structure the Vest-style First-aid Kit has the advantages of fully freeing both hands,and being fit for the ship confined space.Basic performance experiments,ergonomics tests and army tryout were performed and the results showed that the vest-style first-aid kit was scientifically designed,and easy to use,suiting the body,obviously saving physical energy.It has a reasonably designed interior medicine layout and can fulfill the requirements of first-aid operations in naval ships.
