ABSTRACT
@#Objective To systematically evaluate the efficacy and safety of nedaplatin versus cisplatin combined with fluorouracil in the treatment of esophageal neoplasms. Methods PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, WanFang, VIP and CBM databases were searched by computer to investigate the randomized controlled studies about the clinical effects of nedaplatin combined with fluorouracil versus cisplatin combined with fluorouracil in the treatment of esophageal neoplasms. The retrieval time was from the establishment of the database to January 2021. And meta-analysis was performed using RevMan 5.4. Results A total of 12 randomized controlled studies involving 744 patients were included. The results of meta-analysis showed that the total effective rate of the nedaplatin group was better than that of the cisplatin group (P<0.05). The incidence of nausea, vomiting, diarrhea and renal impairment in the nedaplatin group was lower than that in the cisplatin group (P<0.05), but the incidence of leukopenia and hemoglobin decline was higher than that in the cisplatin group (P<0.05). There was no statistical difference in the incidence of liver injury, or platelet decline between the two groups (P>0.05). Conclusion Nedaplatin combined with fluorouracil has more advantages than cisplatin combined with fluorouracil in the treatment of esophageal cancer, the incidence of nausea, vomiting and diarrhea is lower, and the damage to kidney function is also smaller.
ABSTRACT
Objective:To assess the association between warm ischemia time (WIT) and renal function in patients undergoing laparoscopic partial nephrectomy.Methods:A total of 344 patients treated with laparoscopic partial nephrectomy in Peking University People’s Hospital were included. There were 240 males (69.8%) and 104 females (30.2%) with a median age of 57 (23-89) years.The median BMI was 25.6 (16.7-36.0) kg/m 2.213 cases (61.9%) were associated with hypertension.There were 66 (19.2%) patients with diabetes mellitus. There were 92 cases (26.7%) with smoking history. The median preoperative creatinine was 73 (32-170) μmol/L. The median preoperative estimated glomerular filtration rate (eGFR) was 95 (33-142) ml/(min·1.73m 2). The maximum diameter of the tumor was 2.5 (7-9) cm.314 (91.3%) patients with renal cancer stage T 1. All patients underwent warm ischemia during the operation. The patients were divided into three groups for analysis. Restricted cubic spline regression analysis was used to assess the association between WIT as a continuous variable and percentage change of eGFR. Analysis of covariance was used to compare postoperative eGFR among the three groups, and to adjust for preoperative eGFR and tumor diameter. Results:There were statistically significant differences in the percentage change of postoperative eGFR ( P=0.009) and tumor diameter ( P<0.001) among the three groups. Restricted cubic spline regression analysis showed that with the prolongation of WIT, the percentage change of postoperative eGFR gradually decreased, and the curve began to stabilize after 30 minutes (R 2=0.044, P=0.015). The results of covariance analysis showed that after adjusting for baseline preoperative eGFR and tumor size, the effect of WIT on postoperative eGFR was significantly different among the three groups ( F=3.864, P=0.022). The postoperative eGFR in the WIT<20 min group was significantly higher than that in 20 min≤WIT<30 min group( P=0.009) and WIT≥30 min group( P=0.017). There was no significant difference in postoperative eGFR between the two groups with longer WIT( P=0.806). Conclusions:In partial nephrectomy, patients with WIT less than 20 minutes had higher postoperative eGFR levels than those with WIT greater than 20 minutes. However, when WIT exceeded 20 minutes, prolonged ischemia time did not lead to further decline in renal function.
ABSTRACT
Objective:To observe the repairing effect of ozone water injection in the articular cavity for the treatment of knee osteoarthritis (KOA) on articular cartilage and to explore its repair mechanism.Methods:48 rats were randomly divided into fourgroups, the normal, model, normal saline and ozone water group, each group had 12 rats. The rats were injectied into the joint cavity with papain to establish a KOA model other than the normal group. After confirming the success of the model, the ozone water group and normal saline group was treated with ozone water and normal saline injection into the joint cavity once a week for a total of 3 treatments, the normal group and the model group are all raised routinely. Before and after the treatment, the ratknee joint behavioral score MG score was conducted; after the treatment articular cartilage surface gross score, hematoxylin and eosin (HE) staining and modified Mankin score of articular cartilage pathological changes was measured, and Western blot and Rt-PCR to measure the level of protein and mRNA expression of NF-κB p65, IKKβ and IκBα in articular cartilage tissues.Results:Compared with before the treatment, the rat knee joint behavioral score of the ozone water group was significantly lower (all P<0.05); after the treatment, the gross articular cartilage surface score and the modified Mankin score of the ozone water group were significantly reduced compared with the model and normal saline group (all P<0.05); Compared with the model and normal saline group, the protein and mRNA expression levels of NF-κB p65 and IKKβ in the ozone water group are significantly lower (all P<0.05), and the levels of IκBα are significantly higher (all P<0.05). Conclusion:Ozone water injection in the articular cavity can effectively repair damaged articular cartilage. The repair mechanism may be achieved by inhibiting the activation of NF-κB signaling pathway.
ABSTRACT
@#Objective To evaluate the feasibility and safety of da Vinci robotic surgery for elderly patients with radical surgery of lung cancer. Methods We retrospectively analyzed the clinical data of 59 patients aged over 70 years who underwent radical surgery of lung cancer in our hospital between 2016 and 2019. These patients were divided into two groups including a da Vinci robot group and a single-utility port video-assisted thoracoscopic surgery (VATS) group according to the patients’ selection of the treatments. There were 32 patients with 20 males and 12 females aged 73.1±2.3 years in the da Vinci robot group and 27 patients with 16 males and 11 females aged 71.2±1.3 years in the VATS group. The clinical data of the two groups were compared. Results There was no statistical difference in surgery time between the two groups (t=–0.341, P=0.484). Compared with the VATS group, the da Vinci robot group had more number of lymph nodes dissected (t=1.635, P=0.015), less intraoperative blood loss (t=–2.569, P <0.001), less postoperative drainage amount within 3 days after surgery (t=–6.325, P=0.045), lower visual analogue scale (VAS) scores at postoperative 3rd day (t=–7.214, P=0.021). Conclusion The da Vinci robot system is safe and efficient in the treatment for elderly patients with radical surgery of lung cancer with less trauma.
ABSTRACT
@#Objective Through the perioperative outcome analysis of da Vinci robot-assisted sleeve lobectomy, to clarify its efficacy and safety. Methods A retrospective analysis was performed on 10 patients with centrally located lung cancer undergoing robot-assisted sleeve lobectomy from March to December 2019 in our center, including 9 males and 1 female, aged 45-67 (55.0±8.9) years. Preoperative imaging and bronchoscopy showed central non-small cell lung cancer, involving the right upper lung in 3 patients, right lower lung in 2 patients, the left upper lung in 4 patients, and left lower lung in 1 patient. The operation time, Docking time, intraoperative blood loss volume, bronchial anastomosis time, number of dissected lymph nodes, drainage volume and postoperative hospital stay were analyzed. Results The da Vinci robot-assisted bronchial sleeve lobectomy was completed smoothly on 10 patients. The operation time was 135-183 (157.8±14.3) min, Docking time 6-15 (10.0±2.9) min, intraoperative blood loss volume 55-250 (124.5±61.8) mL, bronchial anastomosis time 17-40 (27.7±7.3) min, the number of dissected lymph nodes 16-23 (19.7±2.8), the drainage volume 200-600 (348.0±148.4) mL and postoperative hospital stay 7-11 (8.7±1.6) d. All patients had no bronchopleural fistula, pulmonary infection or atelectasis, and there was no perioperative death. Postoperative pathological findings were all squamous cell carcinoma. Conclusion Da Vinci robot-assisted sleeve lobectomy is safe and effective.
