The treatment landscape for metastatic renal cell carcinoma(mRCC)has evolved rapidly over the past two decades with the introduction of targeted therapies and novel immune checkpoint inhibitors.Among these developments,cytoreductive nephrectomy(CN)remains a controversial and unresolved issue,with its survival benefits being questioned compared to systemic therapy(ST).The role and optimal timing of CN in the context of modern systemic treatment for mRCC remain unclear.Additionally,there is still no well-defined consensus on patient selection for CN.Therefore,this article provides a concise review of current evidence regarding CN in mRCC,incor-porating the latest renal cancer management guidelines.We focus particularly on optimal surgical timing,candidate patient selection,and the therapeutic value of metastasectomy.Furthermore,we examine the current role of CN in metastatic non-clear cell renal cell carcinoma and explore its evolving clinical applications and future prospects in mRCC treatment.

This study constructed a nano-drug delivery system, A3@GMH, by co-delivering the stapled anoplin peptide(Ano-3, A3) with the light-harvesting material graphene oxide(GO), and evaluated its oncolytic immunotherapy effect on triple-negative breast cancer(TNBC). A3@GMH was prepared using an emulsion template method and its physicochemical properties were characterized. The in vivo and in vitro photothermal conversion abilities of A3@GMH were investigated using an infrared thermal imager. The oncoly-tic activity of A3@GMH against TNBC 4T1 cells was evaluated through cell counting kit-8(CCK-8), lactate dehydrogenase(LDH) release, live/dead cell staining, and super-resolution microscopy. The targeting properties of A3@GMH on 4T1 cells were assessed using a high-content imaging system and flow cytometry. In vitro and in vivo studies were conducted to investigate the antitumor mechanism of A3@GMH in combination with photothermal therapy(PTT) through inducing immunogenic cell death(ICD) in 4T1 cells. The results showed that the prepared A3@GMH exhibited distinct mesoporous and coated structures with an average particle size of(308.9±7.5) nm and a surface potential of(-6.79±0.58) mV. The encapsulation efficiency and drug loading of A3 were 23.9%±0.6% and 20.5%±0.5%, respectively. A3@GMH demonstrated excellent photothermal conversion ability and biological safety. A3@GMH actively mediated oncolytic features such as 4T1 cell lysis and LDH release, as well as ICD effects, and showed enhanced in vitro antitumor activity when combined with PTT. In vivo, A3@GMH efficiently induced ICD effects with two rounds of PTT, activated the host's antitumor immune response, and effectively suppressed tumor growth in 4T1 tumor-bearing mice, achieving an 88.9% tumor inhibition rate with no apparent toxic side effects. This study suggests that the combination of stapled anoplin peptide and PTT significantly enhances the oncolytic immunotherapy for TNBC and provides a basis for the innovative application of anti-tumor peptides derived from TCM in TNBC treatment.

Bladder cancer(BC) ranks the first of genitourinary tumor in China and is one of the most common urological malignancies, in which 25%-30% of patients were diagnosed with muscle-invasive bladder cancer. Radical cystectomy combined with pelvic lymph node dissection is the standard procedure for treatment, which can effectively avoid tumor recurrence or distant metastasis as well as improve the prognosis of patients. However, some patients may not tolerate or refuse to undergo radical bladder surgery due to worry about high complication rate, high morbidity and poor postoperative quality of life. With the increasing understanding of bladder cancer heterogeneity and biological behavior, the treatment of bladder cancer has changed from a surgery-based treatment model to an individualized and comprehensive treatment model by multidisciplinary collaboration. The bladder-preserving treatment can achieve the same oncological prognosis as that of radical bladder surgery with a better quality of life of the patients, which has become a hot topic and focus of research in muscle-invasive bladder cancer treatment. This article reviewed the progress of research related to the comprehensive treatment of muscle-invasive bladder cancer with preservation of the bladder.

Near-infrared spectroscopy(NIRS) combined with band screening method and modeling algorithm can be used to achieve the rapid and non-destructive detection of the traditional Chinese medicine(TCM) production process. This paper focused on the ginkgo leaf macroporous resin purification process, which is the key technology of Yinshen Tongluo Capsules, in order to achieve the rapid determination of quercetin, kaempferol and isorhamnetin in effluent. The abnormal spectrum was eliminated by Mahalanobis distance algorithm, and the data set was divided by the sample set partitioning method based on joint X-Y distances(SPXY). The key information bands were selected by synergy interval partial least squares(siPLS); based on that, competitive adaptive reweighted sampling(CARS), successive projections algorithm(SPA) and Monte Carlo uninformative variable(MC-UVE) were used to select wavelengths to obtain less but more critical variable data. With selected key variables as input, the quantitative analysis model was established by genetic algorithm joint extreme learning machine(GA-ELM) algorithm. The performance of the model was compared with that of partial least squares regression(PLSR). The results showed that the combination with siPLS-CARS-GA-ELM could achieve the optimal model performance with the minimum number of variables. The calibration set correlation coefficient R_c and the validation set correlation coefficient R_p of quercetin, kaempferol and isorhamnetin were all above 0.98. The root mean square error of calibration(RMSEC), the root mean square error of prediction(RMSEP) and the relative standard errors of prediction(RSEP) were 0.030 0, 0.029 2 and 8.88%, 0.041 4, 0.034 8 and 8.46%, 0.029 3, 0.027 1 and 10.10%, respectively. Compared with the PLSR me-thod, the performance of the GA-ELM model was greatly improved, which proved that NIRS combined with GA-ELM method has a great potential for rapid determination of effective components of TCM.

Objective:To compare the effect of hybrid open-endovascular repair (HOER) and Viabahn open revascularization technique (VORTEC)+HOER in the treatment of thoracoabdominal aortic aneurysms (TAAA).Methods:From Apr 2005 to Jul 2019, 33 TAAA patients underwent HOER including 21 cases of standard HOER, and 12 of VORTEC+HOER. The intraoperative renal ischemia time (RIT), incidence of postoperative acute kidney injury (AKI), rate of renal artery patency (RAP) and another short-term outcome were observed.Results:RIT was significantly shorter in the VORTEC+HOER group than in the standard treatment group [(9±3) minutes vs. (15±6) minutes, P<0.05]. The increase in serum creatinine (SCr) levels on the 1st postoperative day in the standard treatment group was significantly higher than that in the VORTEC+HOER group [(1.68±0.79) μmol/L vs. (1.05±0.06) μmol/L, P<0.05]. AKI occurred in 5 patients in the standard HOER treatment group (5/21, 24%), while no patient experienced AKI in the VORTEC+HOER group (0/12, 0). Conclusion:VORTEC significantly reduces RIT and postoperative SCr increasing, thereby potentially decreasing the incidence of postoperative AKI.
