ABSTRACT
Objective:To investigate the efficacy of tyrosine kinase inhibitors (TKI) in the treatment of metastatic renal cell carcinoma with rhabdoid differentiation(mRCC-R) or sarcomatoid differentiation(mRCC-S)and the survival of the patients.Methods:The clinicopathological and postoperative follow-up data of 5 patients with mRCC-R and 9 with mRCC-S confirmed by pathology from February 2016 to December 2018 in Tianjin Medical University Cancer Hospital were reviewed. There were 3 male and 2 female patients in mRCC-R group, with the average age of (60.2±7.1)years old. The clinic manifestation included back or abdominal pain in 2 cases, loss of appetite and weight in one case and founding during physical examination in 2 cases, with the average maximum diameter was (8.8±4.1)cm. The site of tumor included left kidney in 3 cases and right kidney in 2 cases. Lung metastasis was found in 4 cases. Lung and peritoneum metastasis was found in one case. There were 8 male and 1 female patients in mRCC-S group, with the average age of (58.0±8.0)years old. The clinic manifestation included back or abdominal pain in one case, loss of weight in one case, gross hematuria in one case and founding during physical examination in 6 cases. The average diameter of tumor was (8.9±3.5)cm. The site of tumor included left kidney in 4 cases and right kidney in 5 cases. Postoperative metastasis included lung in 3 cases, bone in one case, retroperitoneal lymph node in one case, brain in one case, lung associated with bone in one case. All of the patients were pathologically diagnosed with renal clear cell carcinoma. After metastasis, 5 cases of mRCC-R and 6 cases of mRCC-S were treated with Sorafenib, 2 cases of mRCC-S were treated with Sunitinib, and 1 case of mRCC-S was treated with Axitinib. The efficacy of TKI for the two specific pathological types and for single pathological type at the early postoperative period (within 3 months) and 3 months later was compared. Meanwhile, subgroup analysis was performed on the efficacy of TKI and survival of patients with same metastatic sites in the two groups.Results:The mean overall survival(OS) of mRCC-R and mRCC-S treated with TKI was (26.5±5.5)months and (20.7±4.7) months( P=0.329), and the mean progression-free survival (PFS) was (21.9±5.5) months and (6.3±2.1)months( P=0.013), respectively. Comparing the efficacy of using TKI in the early postoperative period and after 3 months, the mean OS was (27.5±6.5)months and (16.8±6.1)months ( P=0.619), and the mean PFS was (12.3±3.3)months and (3.3±1.7)months ( P=0.096), respectively. There was only 1 patient with mRCC-R who used TKI within 3 months after surgery, and the result was disease progressed and eventually died, OS was 3 months. Comparing the efficacy of TKI in mRCC-R and mRCC-S with lung metastasis alone, the mean OS was (33.3±2.2) months and (19.5±8.9)months ( P=0.118), and the mean PFS was (27.3±3.1) months and (7.8±4.2) months ( P=0.009), respectively. Patients with liver, bone or brain metastasis only occurred in mRCC-S, so it is unable to identify the efficacy of TKI in the two groups. Conclusions:The efficacy of TKI in the treatment of mRCC-R was better than mRCC-S, and there was statistically significant difference in PFS, especially in patients with lung metastasis alone in the two groups. There was no significant difference in the efficacy between patients with mRCC-R who took TKI in the early postoperative period (within 3 months)and those who took TKI after 3 months.
ABSTRACT
Objective@#To investigate the clinical features and prognostic factors of extrahepatic biliary neuroendocrine neoplasms(EB-NENs).@*Methods@#The clinical data and survival of 21 patients with EB-NENs admitted from May 2014 to May 2018 were analyzed retrospectively.@*Results@#These 21 EB-NENs patients accounted for 1.6% (21/1313) of all biliary tract neoplasms treated during the study period. Seven (33.3%) cases had lymph node metastasis. Five (23.8%) suffered from distant metastasis. The follow up time was (4~46.5) months with median survival time of (23.23 ±4.17) months. Univariate analysis showed that the risk factors for survival were tumor TNM stage (χ2=9.066, P=0.003), lymph node metastasis(χ2=6.399, P=0.011) and distant metastasis (χ2=9.808, P=0.002). By multivariate analysis, independent risk factors were tumor TNM stage(P=0.008, RR=3.003, 95% CI: 1.332~6.774), lymph node metastasis(P=0.023, RR=5.382, 95% CI: 1.261~22.971) and distant metastasis or not(P=0.007, RR=7.423, 95% CI: 1.730~31.851).@*Conclusion@#EB-NENs was a rare malignant tumor with poor prognosis. Tumor TNM stage, lymph node metastasis and distant metastasis were independent prognostic factors for EB-NENs patients.

ABSTRACT
Objective To explore the teaching efficacy of applying scene simulation in enteral nutrition nursing skills training.Methods Totally 126 nursing students were randomly divided into 2 groups:experiment group with scene simulation teaching method and control group with traditional teaching method.Comparison of teaching efficacy between the two methods was made.Results The students in experiment group can skillfully complete nutritional care and get the praise of teachers.The satisfied patients made by students in experiment group were higher than those in control group 14.28％ - 19.05 ％ ( P＜0.05 ).The assessment scores of theoretic knowledge test and enteral nutrition nursing manipulation examination and comprehensive nursing skill test were higher in experimental group than in control group 6.69 - 11.94 ( P＜0.005 ).Conclusion Scene simulation teaching method is suitable for enteral nutrition nursing skill training and is favored by nursing students.
