ABSTRACT
【Objective】 To evaluate the significance of Mayo adhesive probability (MAP) in predicting surgical difficulty and postoperative recovery in patients with renal cell carcinoma (RCC) undergoing laparoscopic radical nephrectomy (LRN). 【Methods】 The clinical data of 168 RCC patients who received transabdominal LRN during Jan.2017 and Dec.2020 were retrospectively analyzed. According to MAP, the patients were divided into low MAP group (n=100) and high MAP group (n=68). The differences in perioperative clinical data were compared between the two groups. 【Results】 Compared with low MAP group, the high MAP group had longer operation time (P<0.001), more intraoperative blood loss (P<0.001), higher Clavien-Dindo grade complications (P=0.008), longer hospital stay (P=0.003), higher levels of c-reactive protein (P=0.030) and IL-6 (P=0.009), lower levels of albumin (P<0.001) and prealbumin (P=0.020). 【Conclusion】 MAP can assess the risk of prolonged operation time, increased bleeding during transabdominal LRN, and postoperative recovery, thus guiding the preoperative planning.
ABSTRACT
Forty trainees who underwent position-transition training for general practitioner in the Affiliated Huai′an First People′s Hospital of Nanjing Medical University from August 2021 to July 2022 were randomly divided into the control group and the trial group with 20 in each group. The traditional teaching methods were applied in control group and the problem-based learning/case-based learning (PBL/CBL) combined scenario simulation teaching method were applied in trial group. The effect of the two teaching methods was evaluated by the examination results and the teaching satisfaction was assessed by the questionnaire survey. The exam scores of general practice thinking, comprehensiveness of inquiry content, integrity of preliminary diagnosis, comprehensiveness of preliminary treatment, ability to deal with critical and severe cases, ability of chronic disease management and concept of holistic care in trial group were significantly higher than those in control group( t=-15.79,-15.74,-16.67,-13.66,-18.57,-18.55,-19.74,all P<0.05). The satisfaction of trainees in the trial group was also significantly higher than that in the control group in terms of teaching methods, stimulating learning interest; and improvement of independent learning ability, general practice clinical thinking, doctor-patient communication ability, teamwork ability and community problem-solving ability( χ2=12.10,10.03,12.22,10.03,8.18,10.03,8.18,all P<0.05). The study shows that PBL/CBL combined scenario simulation teaching method can improve the learning effect and satisfaction of the trainees in position-transition training for general practitioner.
ABSTRACT
Objective:To evaluate the effect of uncoupling protein 1 (UCP1) expression of perirenal fat on the prognosis of clear cell renal cell carcinoma (ccRCC) .Methods:From Feb. 2013 to Oct. 2013 and Mar. 2015 to Oct. 2015, 98 patients with ccRCC who underwent retroperitoneal laparoscopic radical nephrectomy were analyzed. UCP1 mRNA of perirenal fat around tumor was detected by RT-qPCR. Preoperative Computed tomography (CT) images were used to evaluate the thickness and adhesiveness of perirenal fat. According to the UCP1 mRNA value, the patients were divided into high UCP1 group (42 cases) and low UCP1 group (56 cases) . The general clinical data, perirenal fat thickness and adhesiveness were compared, and Kaplan Meier curve was used to evaluate the difference of progression free survival (PFS) between the two groups. Univariate and multivariate Cox analysis were used to determine the potential independent prognostic factors of PFS.Results:In the high UCP1 group, the renal fat thickness, the ratio of fat adhesion, the ratio of Ⅲ to Ⅳ in Fuhrman grade and the ratio of >T2 in T stage were higher than those in the low UCP1 group[ (13.84±2.41) vs (10.75±1.99) , 42.86% vs 16.07%, 28.57% vs 8.93%, 21.43% vs. 5.36%; P=0.000, P=0.003, P=0.011, P= 0.037]. During the follow-up period (median, 62.0 months) , 15 cases (12 cases of high UCP1 group, 3 case of low UCP1 group) developed tumor progression. Kaplan Meier curve showed that PFS of high UCP1 group was worse than that of low UCP1 group (71.43% vs 94.64%, P=0.001) . Cox regression analysis showed that high UCP1 expression and high T stage were significantly correlated with low PFS ( β=1.334, RR=3.796, 95% CI=1.009-14.280, P= 0.048; β=2.886, RR=17.930, 95% CI=5.538-58.047, P=0.000) . Conclusions:The increased UCP1 expression of perirenal fat may be an independent risk factor of tumor progression in ccRCC. Combined with the assessment of browning of perirenal adipose tissue may be helpful for risk stratification of ccRCC patients after surgery.
ABSTRACT
Objective@#To determine the change of gene expressions in human perirenal adipose tissue (PAT) and oblique abdomen subcutaneous adipose tissue (SAT) of overweight and obese subjects.@*Methods@#Ninety-seven patients, including 35 overweight/obese patients and 62 non-obese patients, who underwent renal surgery were included. The clinical data and various gene expressions in PAT and SAT of two groups were analyzed.@*Results@#Body mass index, waist circumference, systolic blood pressure, resting heart rate, fasting blood glucose, and serum creatinine were significantly higher in overweight/obese patients than those in non-obese patients(P<0.05 or P<0.01). Compared with non-obese patients, PAT adipocytes showed bigger, and the expressions of uncoupling protein-1 (UCP1) mRNA and protein were markedly lower in overweight/obese patients. The mRNA expressions of CIDEA and adiponectin in PAT of overweight/obese patients were significantly lower, while leptin, monocyte chemotactic protein 1, interleukin (IL)-6, and IL-10 mRNA expressions were significantly higher. There were no significant differences in the related gene expressions of SAT between the two groups.@*Conclusions@#Different parts of adipose tissue reveal various characteristics, and play different roles in the occurrence and development of obesity. UCP1 expression is decreased in PAT of overweight/obese patients, with the changes of adipocytokine expressions. (Chin J Endocrinol Metab, 2018, 34: 567-572)
