Renal cell carcinoma is one of the most common malignant tumors of the urinary system.Radiomics,as a non-invasive and efficient diagnostic method,can extract high-throughput imaging features imperceptible to the human eye,offering new possibilities for precise diagnosis and evaluation of renal cell carcinoma.However,radiomics often treats the entire tumor as a homogeneous region,overlooking intratumoral heterogeneity and exhibiting poor biological interpretability.As an emerging imaging technology based on biological contexts,habitat imaging utilizes quantitative imaging biomarkers to delineate distinct spatial regions with similar biological characteristics within a tumor,thereby visualizing and quantifying intratumoral heterogeneity.This article reviews and prospects the advances and future directions of radiomics and habitat imaging in renal cell carcinoma.

Portal vein embolization （PVE） can induce atrophy of the embolized lobe and compensatory regeneration of the non-embolized lobe. However， due to inadequate regeneration of future liver remnant （FLR） after PVE， some patients remain unsuitable for hepatectomy after PVE. In recent years， liver venous deprivation （LVD）， which combines PVE with hepatic vein embolization （HVE）， has induced enhanced FLR regeneration. Compared with associating liver partition and portal vein ligation for staged hepatectomy （ALPPS）， LVD triggers faster and more robust FLR regeneration， with lower incidence rate of postoperative complications and mortality rate. By reviewing related articles on LVD， this article introduces the effectiveness of LVD and analyzes the differences and safety of various technical paths， and it is believed that LVD is a safe and effective preoperative pretreatment method.

Objective:To explore the clinical diagnosis and treatment of common bile duct stones (CBDS) in military pilots and the aeromedical assessment.Methods:The detailed diagnosis and treatment process, as well as the aeromedical assessment of 3 military pilots diagnosed as CBDS in Air Force Medical Center, PLA from June 2009 to March 2015 were collected. Then it was analyzed by the new technology.Results:Three pilots were diagnosed as CBDS and obstructive jaundice due to long term cholecystolithiasis or calculus of intrahepatic duct. Case 1 was secondary to cholecystolithiasis, and received laparoscopic cholecystectomy and common bile duct exploration. Case 2 was secondary to intrahepatic cholelithiasis and underwent left lateral lobectomy and common bile duct exploration. Case 3 recurred after cholecystolithotomy and then underwent open cholecystectomy, choledochoplasty and T-tube drainage because of biliary stricture. All 3 cases recovered well. The aeromedical assessment conclusions were as follows: case 1 was qualified to flight 5 months after operation, case 2 was grounded due to hypertension after the operation, case 3 was qualified after 6 months of the operation.Conclusions:CBDS of military pilots is often secondary to cholecystolithiasis or intrahepatic bile duct stones. The operation should be performed as early as possible, and minimally invasive methods should be adopted. The pilots with proper treatment and good postoperative recovery can be qualified to flight.

Objective:To present our initial experience with robot-assisted laparoscopic prostatectomy (RALP) for complicated cases.Methods:Clinical and pathological data from 4 complicated prostate cancer cases,who underwent RALP from October to November in 2015,were analyzed retrospectively.All the cases were conducted transurethral plasmakinetic enucleation of prostate and hormonal therapy before RALP.Results:All surgeries were done successfully.The age,baseline prostatic special antigen,clinical tumor stage,operation time and estimated blood loss were 58-70 years,6.04-70.15 ng/mL,T2bT3b,210-360 min and 50-250 mL,respectively.No blood transfusion was needed.All surgical margin were negative.Conclusion:Although previous transurethral surgeries and hormonal therapies may increase the difficulty for operations,RALP is still appropriate for the complicated cases of prostate cancer.

Objective To verify the association between common breast cancer susceptibility loci which have been confirmed in European and Asian populations and breast cancer susceptibility in sporadic breast cancer among the Han nationality in Henan province , and to analyze their genotypes in the internal type of breast cancer . Methods In 253 breast cancer patients ( the case group ) and 343 patients who had benign breast lesions ( the control group), rs2046210(6q25.1), rs2981582(EGFR2), rs889312(MAP3K1), and rs3803662(TOX3/TNRC9)were genotyped by SNP im-LDR technique.According to estrogen receptor(ER), progesterone receptor (PR), human epidermal growth factor receptor 2(HER2)and Ki67, breast cancer are divided into 5 types:Lu-minal A, Luminal B, HER2-enrich, Luminal HER2, and triple negative breast cancer ( TNBC).Results rs2046210(6q25.1), rs2981582(EGFR2), rs889312(MAP3K1)had no statistical differences between the case group and the control group(P=0.421, 0.459, and 0.468), but the genotype of rs3803662(TOX3/TNRC9)in the case group and the control group had statistical difference (P=0.037).The allelic frequencies of rs3803662 between the case group and control group were different in codominant inheritance ( OR=2.19, 95%CI:1.19-4.02)and recessive genetic models (OR =2.06,95% CI:1.15 -3.70).Compared with AA and GA, GG in-creased the risk of breast cancer ( P =0.012, 0.015 ).The genotypes of rs2046210 ( 6q25.1 ), rs2981582 (EGFR2), rs889312(MAP3K1), and rs3803662(TOX3/TNRC9)had no difference in different types of breast cancer.Conclusions Four common breast cancer susceptibility loci from GWAS are not entirely associated with breast cancer risk among the Han nationality in Henan province .Only rs3803662(TOX3/TNRC9)is confirmed to increase the risk of breast cancer .Different genotypes of 4 loci distribute equally in different types of breast cancer .

Objective To investigate the relationship between RAD51 135G ＞ C polymorphism and prognosis in triple-negative breast cancer patients by retrospective analysis.Methods The clinical data of 62 triplenegative breast cancer patients were collected.The 62 cases underwent standard chemotherapy and radiotherapy after tumor resection from Jan.2004 to Dec.2010 in Affiliated Cancer Hospital of Zhengzhou University.RAD51 135G ＞ C polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RELP) technology.The survival curve about progress free and overall survival time were then made.Results The median progress free and overall survival time in triple-negative breast cancer patients with or with-out RAD51 135G ＞ C polymorphism were(77.00 ±5.55)and(89.00 ± 10.40) months vs(99.00 ±4.26)and (103.00 ±4.30) months.The difference had statistical significance(P =0.039 and 0.015 respectively).Conclusion RAD51 135G ＞ C polymorphism is related with prognosis of triple-negative breast cancer patients,which might be a prognostic factor for breast cancer.

Objective To discuss the protein level of hypoxia-inducible factor 1-alpha(HIF-1α),glucose transporter-1 (Glut-1)and vascular endothelial growth factor(VEGF) in breast cancer tissue in diabetic patients and its significance.Methods HIF-1α,Glut-1 and VEGF protein levels were measured by immunohistochemical staining in 112 cases of primary breast cancer tissues.CD31 labeled vascular endothelial cells were used to evaluate micro vascular density (MVD).The correlation between the effect of blood sugar control and clinicopathological parameters was analyzed.Results The expression of HIF-1α,Glut-1 and VEGF protein in breast cancer tissues of diabetic patients was significantly higher than that in breast cancer tissues of non-diabetic patients(t =2.255,P =0.030; t =2.154,P=0.038; t =2.225,P =0.032).HIF-1α was positively correlated with Glut-1 and VEGF in diabetic patients with breast cancer (r =0.561,P =0.003 ; r =0.435,P =0.014).The level of MVD in breast cancer tissues of diabetic patients was obviously higher than that in the non-diabetic patients with breast cancer(t =9.458,P =0.000).The effect of blood sugar control was significantly correlated with lymph node metastasis and tumor stage in diabetic patients with breast cancer(x2 =4.689,P =0.030; x2 =5.051,P =0.025).Conclusion Hypoxia-related factors including HIF-1α,Glut-1 and VEGF and MVD are upregulated in diabetic patients with breast cancer,and the effect of blood sugar control is correlated with lymph node metastasis and tumor stage,suggesting diabetes mellitus may promote tumor progression through high glucose and hypoxia in breast cancer.
