Renal cancer is a common malignant tumor in urology, with complicated pathogenesis and no obvious clinical symptoms. Metastatic renal cancer accounts for 20%-30% of the newly diagnosed renal cancer. The 5-year survival rate for metastatic patients is less than 10%.At present, the main non-surgical treatment means of mRCC include cytokines and targeted drug therapy, and immunotherapy has also become a research hotspot of mRCC. The current status and research progress of mRCC therapy were reviewed. The medical treatment methods of metastatic renal cancer, such as receptor tyrosine kinase inhibitors and mTOR inhibitors; immunotherapies, such as immunosuppressants for PD-1/PD-L1 were also discussed.

Objective:To evaluate the efficacy of amiodarone in preventing reperfusion ventricular fibrillation (RVF) in patients undergoing cardiac surgery.Methods:This study searched the databases of CNKI, Wanfang, Weipu, Cochrane, Embase, Web of Knowledge and PubMed, and searched the related research of amiodarone to prevent RVF in cardiac surgery patients, the time was until December 2019. Meta analysis was performed using Revman 5.3 software according to established standards.Results:The study included six studies (incorporating 514 patients). According to different intervention methods, 514 patients were divided into three groups, 196 in the amiodarone group, 153 in the lidocaine group, and 165 in the placebo group. The incidence of RVF was significantly lower in the amiodarone group than in the control group ( RR: 0.64, 95% CI: 0.47-0.86, P=0.003, I2=49%), but there was no significant difference between the amiodarone group and the lidocaine group( RR: 1.03, 95% CI: 0.48-2.22, P=0.94, I2=74%). Compared with the control group, amiodarone reduced the defibrillation frequency of RVF, but the difference was not statistically significant ( RR: 0.90, 95% CI: 0.68-1.20, P=0.48, I2=0). There was no difference in the number of defibrillation of RVF between the lidocaine group and the amiodarone groups ( RR: 1.50, 95% CI: 0.90-2.52, P=0.12, I2=38%). Conclusion:Compared with the control group, amiodarone can significantly reduce the incidence of RVF in patients undergoing cardiac surgery.

The therapy of removing beat and toxic,strengthening the body to cultivate the fundamental is the mainstream of treating cancer in traditional Chinese medicine up to now,and the therapy of warming yang has been rarely involved.While the pathogenesis of tumor is spleen and kidney yang deficiency in root,and phlegm,stasis,and poison entangled with each other at the secondary position; the main therapeutical principle of tumor is simultaneous application of purging-tonifying therapy while focusing on protecting yang.The author believes that the treatment of cancer should pay attention to the whole concept,especially warming yang for patients with advanced tumors.The therapy of warming yang is an effective way to get rid of phlegm and blood stasis.Patients after radiotherapy and chemotherapy should be paid more attention to warming yang.

Objective To explore the protective role and mechanisms of glucagon-like peptide-1(GLP-1) on advanced oxidation protein products (AOPPs)-induced apoptosis of cardiomyocytes. Methods The H9C2 cells were selected in this study and divided into blank control group,RSA control group,and groups treated with indicated concentrations of AOPPs with or without GLP-1,and AOPPs +GLP-1+LY294002 for 24 hours respectively. Cell viability was detected by CCK-8 assay. The ROS level was detected by DCFH-DA fluorescent probe. The cell apoptosis was tested by fluorescent staining and flow cytometry. The expression of p-Akt,p-Bad,Bcl-2,Bax,and active-caspase-3 proteins were evaluated by Western blot. Results GLP-1 attenuated AOPPs-induced cytotoxicity[(0.929±0.083) vs (1.409±0.099),P<0.01],decreased AOPPs-induced ROS[(47.817±0.878)% vs (25.413±2.597)%,P<0.01] and apoptosis[(15.773±3.130)% vs (9.715±0.757)%,P<0.01]. GLP-1 improved AOPPs-induced phosphorylation of Akt and Bad,increased the expression of Bcl-2,and decreased the expression of Bax and the activation of caspase-3. Conclusion GLP-1 protects cardiomyocytes against AOPP-induced apoptosis,predominantly via the PI3K/Akt/Bad pathway.

Objective To observe the effect of ephedrine on the expression of eotaxin in human bronchial epithelial cells (16HBE) stimulated by tumor necrosis factor‐α(TNF‐α) and to explore the mechanism of Chinese medicine ephedra in treating asthma .Methods The in vitro cultured 16HBE were randomly divided into the control group ,TNF‐αstimulation group(TNF‐α20 ng/mL) and TNF‐αplus ephedrine group (TNF‐α20 ng/mL plus ephedrine 300 μg/mL) .Three complex holes in each group were set to culture for 18 h ,the eotaxin mRNA expression was measured by real time fluorescent quantified PCR and protein level was detected by immunocytochemical stain and Western blot .The eotaxin concentration in cells culture supernatant was quantified by ELISA .Results Compared with the the control group ,the expression level of eotaxin mRNA and protein ,and the concentration of eotaxin in cell culture supernatant in the TNF‐α stimulation group were increased obviously ,there being statisticaly significant difference between them(P<0 .01);however ,all above these parameters in the TNF‐αplus ephedrine group showed decreased obvi‐ously as compared with the TNF‐αgroup ,the difference between them was statistically significant (P<0 .01) .Conclusion Ephed‐rine can inhibit the expression and secretion of eotaxin in TNF‐α induced 16HBE inflammatory model ,which may be one of the mechanisms of Chinese medicine ephedra in treating asthma .

Objective　To explore the effect of photon on blood biologic components in blood photochemical treatment. Methods　After the blood sample was adjusted to an appropriate density, it was treated with 0.1 nmol/ml 8-MOP (8-methoxypsoralen), 0.1 nmol/ml TFO (triple helix-forming oligonuletide) and UVA (ultraviolet A radiation) at the intensity of 1 800 μW/cm2 for 3～20 min. The changes of biologic activities of major components in blood were measured with automatic blood gas analyzer, platelet aggregation analyzer, blood coagulation analyzer, micropipette aspiration system and assay of poly-lysine adsorption. Results　The oxygen content in blood was increased gradually. The resilience of erythrocyte was enhanced ，but its adhesiveness was decreased. The parameters related to blood coagulation had some changes but all remained within the normal ranges. Conclusion　Under the definite condition of blood virus being inactivated effectively, the nonspecific effect of photosensitive response may improve blood oxygen content, enhance the transfiguring ability of erythrocyte and decrease the blood viscosity, but having no obvious change on blood coagulation.

[Objective]To evaluate diagnostic and the therapeutic options of osteoid osteoma of the spine associated with scoliosis. [Methods]Nine patients with osteoid osteoma of the spine were treated from 1997 to 2006.All patients presented with spine deformity as their main complaint at the first consultation.The mean age was 15.2 years (range 8-21 years).Two patients had their osteoid osteoma in the thoracic area,2 in the thorcolumbar area ,and 5 in the lumbar area.Three were well controlled after long term administration of nonsteroidal anti-inflammatory drugs,and the other 6 were treated with en bloc excision.[Results]All the 6 patients with en bloc excision of the tumor were pain-free post-operatively.The scoliotic curve disappeared or was less than 15 degrees in 5,but the structural curve persisted in 4.[Conclusion]The spinal osteoid osteoma should be suspected when back pain or painful scoliosis occurs in adolescents.Computed tomography is necessary to evaluate the location and features of the lesion.En bloc excision of the tumor can be suggested if the symptoms are not well relieved with nonsteroidal anti-inflammatory drugs.

Objective To compare the efficacy of mechanical ventilation (MV) with low tidal volume (LTV) plus positive expiratory end pressure (PEEP) and conventioal MV in the treatment of traumatic acute respiratory distress syndrome(ARDS). Methods From Oct 1997 to Oct 2003, 26 cases of traumatic ARDS patients were treated by conventioal MV(group A, n=11) or MV with LTV plus PEEP(group B,n=15), and clinical data of the patients were recorded and compared. Results There were no statistical difference in the PaO 2 of blood gas analysis and hemodynamic indices between the two groups, while the PaCO 2 was higher in group B than that in group A(P
