Objective To study the expression of NF-κB and COX-2 protein in renal cell carcinoma, and to investigate the clinical value of it in the occurrence, progression and metastasis of renal cell carcinoma as well as the prognosis of patients. Methods 48 cases of renal cell carcinoma tissues and 5 cases of normal renal tissues were detected by using immunohistochemical method, and following up the patients who were included in the study. Then we analyzed the relationship between NF-κB and COX-2 protein level and clinic pathological parameters as well as the prognosis of patients. Resalts The expression of NF-κB and COX-2 protein were increasing in renal cell carcinoma, the protein levels were significantly different compared with that in normal renal tissues(P <0.05). There were significantly positive correlation between the expression of NF-κB protein and the clinic stages of renal cell earcinoma(P <0.05), but no correlation between the expression of COX-2 protein and them(P >0.05). There were significantly negative correlation between the expression of COX-2 protein and the pathological grades of renal cell careinoma(P <0.05), but no correlation between the expression of NF-κB protein and them (P>O.05). The survival rate of these patients whose expression of NF-κB protein were positive was significantly lower than those of negative expression of NF-κB protein(P <0.05), and there was opposite result for COX-2, but not significanfly(P >0.05). The expression of NF-κB and COX-2 protein in renal cell carcinoma had no significant correlation (P >0.05). Conclusion There may be relationship between the expression of NF-κB and COX-2 protein and the occurrence, progression of renal cell carcinoma, the expression of NF-κB may also have association with metastasis of renal cell carcinoma as well as the prognosis of patients. Detecting the expression of NF-κB and COX-2 protein may be useful in early diagnosis of renal cell carcinoma as well as prognosis evaluation of patients.

Objective To evaluate the safety and efifcacy of Laparoscopic partial nephrectomy (LPN) versus 1aparoscopic cryoablation (LCA) for the small renal tumors (SRMs).Methods The databases of PubMed, SCI, Ovid, the Cochrane Library, CNKI, CBM, VIP and Wangfang Data were searched to controlled clinical trial about LPN versus LCA for the treatment of small renal tumor. The retrieval time span was from inception to Apr 2016. The studies were screened according to the inclusion and exclusion criteria, the date were extracted and the quality was evaluated by 2 reviewers independently. And then the Meta-analysis was conducted using RevMan 5.3 software.Results 9 studies were included, and 748 cases were involved. The meta-analysis showed that comparing with LPN, the operation time of LCA was shorter [MD = 42.75, 95 % CI (12.19~73.31),P = 0.006], less intraoperative blood loss [MD = 190.73, 95 % CI (126.67~254.78),P = 0.000], shortening hospital stay [MD = 2.23, 95 % CI (0.17~4.28),P = 0.030], lower transfusion rate [OR^ = 3.54, 95 % CI (1.18~10.59),P = 0.020], lower rate of postoperative glomerular ifltration levels [MD = 10.30, 95 % CI (5.38~15.24),P = 0.000], less complications [OR^= 3.90, 95 % CI (1.84 ~ 8.24),P = 0.000], higher risk of local recurrence [OR^ = 0.13, 95 % CI (0.04 ~ 0.44),P =0.000], higher risk of distant metastases [OR^ = 0.16, 95 % CI (0.03 ~ 0.78),P = 0.020], but there were no signiifcant differences in postoperative creatinine rise and transfusion rate (P > 0.05).Conclusions LCA has advantage in perioperative period results and protect renal function. But LCA has a higher local recurrence and distant metastasis risk, short-term and medium-term efficacy considerably, long-term effect is not clear, therefore, in the choice of surgical cases still need to be careful.

Objective:To investigate the association of muscle mass loss with atherosclerosis in elderly patients with type 2 diabetes mellitus(T2DM).Methods:A total of 322 patients with T2DM aged≥60 years old were divided into muscle mass loss group( n=152) and non-muscle mass loss group( n=170) according to their appendicular skeletal muscle mass index(ASMI). All participants underwent physical examination, dual-energy X-ray absorptiometry check, carotid and lower extremity ultrasound, as well as laboratory tests. Results:Among 322 patients, 49(15.22%) patients were suffered from sarcopenia and 152(47.2%) patients with reduced muscle mass. The carotid and lower extremity atherosclerosis grades in the muscle mass loss group were significantly higher than those in the non-muscle mass loss group( P<0.05), with lower body mass index(BMI), T-score, ASMI, uric acid, and homeostasis model assessment of insulin resistance index( P<0.05). Multivariate logistic regression analysis showed that carotid atherosclerosis and lower extremity atherosclerosis were risk factors for muscle mass loss while BMI and 25-(OH)D 3 were protective factors for muscle mass loss. There existed a consistency in carotid atherosclerosis grade and lower extremity atherosclerosis grade of elderly patients with T2DM( P<0.01). Conclusion:Atherosclerosis has a predictive value for early sarcopenia in elderly patients with T2DM.
