Objective To investigate the characteristics of minimal fat renal angiomyolipoma (MFAML)and clear cell renal cell carcinoma(CCRCC)in high resolution multi-slice spiral CT(MSCT)and to improve the diagnosis accuracy for the renal tumors.Methods A retrospective analysis was performed on 24 MFAML patients(16 females,8 males)with mean age of 43(19-74)years and 24 CCRCC patients(16 females,8 males)with mean age of 44(21-76)years.All patients had undergone MSCT and proved histopathologically after surgery.The characteristics included tumor location,tumor attenuation on unenhanced CT,enhancement characteristics(degree of tumor enhancement in the early corticomedullary phase,homogeneity of enhancement,amount of enhancement,enhancement pattern over time),tumor margin,intratumoral calcification,and perinephric changes.The predictive value of each CT characteristic was determined by using multivariate logistic regression analysis.Results The tumor location in the kidney (upper pole:MFAML,6 cases,CCRCC,6 cases;middle:MFAML,7 cases,CCRCC,9 cases;lower pole:MFAML,11 cases,CCRCC,9 cases)and smooth tumor margin(MFAML,n=21;CCRCC,n=19)were not significantly different between MFAML patients and those with CCRCC,P＞0.05.Twenty-one cases of both MFAMLs and CCRCCs had the significant enhancement in the early corticomedullary phase,which were hypovascular tumors,whereas the mean amount of tumor enhancement was greater in CCRCC than in MFAML in both the early corticomedullary and the corticomedullary phases(CCRCC:175 HU,196 HU;MFAML:125 HU,145 HU;P＜0.05.MFAML usually showed homogeneous enhancement(n=15)rather than heterogeneous enhancement(n =9),whereas most CCRCC showed heterogeneous enhancement(n =17)rather than homogeneous enhancement(n =7),P＜0.05).Enhancement pattern was not a significant predictor.Within the 13 MFAML cases,8 cases had sufficient blood supply(6 cases showed obvious wash-in-and-wash-out,2 cases were with prolonged enhancement),5 cases with hypovascular showed a pattern of prolonged or gradual enhancement,while 21 CCRCC cases had sufficient blood supply and 71％ of them showed obvious wash-in-and-wash-out.High tumor attenuation on unenhanced scans(MFAML:17 patients (75％);CCRCC:2 patients(8％),P=0.002,OR=0.010)and threshold enhancement values of 129.5 HU in the corticomedullary phase(MFAML:5 patients(20％);CCRCC:20 patients(83％),P =0.004,OR =0.057)were valuable predictors for differentiating MFAML from CCRCC at multivariate logistic regression analysis.Conclusions MSCT is useful in differentiating MFAML from CCRCC,with high tumor attenuation on unenhanced scans and threshold enhancement values of 129.5 HU in the corticomedullary phase being the most valuable CT findings.75％ of MFAMLs with sufficient blood supply also show a pattern of wash-in-and-wash-out,which can easily misdiagnosed as a renal cancer.

Objective To detect CYP2J3 gene expression and contents of 11,12-EET in heart,liver,lung,kidney and aorta thoracalis after CYP2J3 gene transfection.Methods The rat transgenic model was developed by injecting plasmid through vena dorsalis penis.The animals were divided into control group、 pcDNA3.1 transgenic group and pcDNA3.1-CYP2J3 transgenic group.The expression of CYP2J3 mRNA was detected by RT-PCR and content of 11,12-EET was examined by the HPLC at 14 days and 28 days after injection.Results Twenty eight days after injection,both expression of CYP2J3 mRNA and the content of 11,12-EET were significantly increased as compared with that of control and pcDNA3.1 transgenic group(P

The vitamin K epoxide reductase complex subunit 1 (VKORC1), the rate-limiting enzyme for vitamin K recycling, is significantly down-regulated in the kidneys of urolithiasis patients. This study searched for direct evidence to define the inhibitory activity of VKORC1 against calcium oxalate (CaOx) crystal formation. In the experiment of VKORC1 overexpression, HK-2 cells were transfected with the pFLAG-CMV-7.1-VKORC1 plasmid as a pFLAG-CMV-7.1-VKORC1 transfection group or the pFLAG-CMV-7.1 plasmid as a pFLAG-CMV-7.1 control group. In the experiment of VKORC1 knockdown, HK-2 cells were transfected with the PGPU6/GFP/Neo-VKORC1shRNA-2 as a PGPU6/GFP/Neo-VKORC1shRNA-2 transfection group or the PGPU6/GFP/Neo-shRNA-NC plasmid as a PGPU6/GFP/Neo-shRNA-NC control group. The expression of VKORC1 in HK-2 cells was detected by real-time quantitative PCR and Western blotting. The CaOx crystal formation was observed under the laser-scanning confocal microscope. It was found that the expression levels of VKORC1 mRNA and protein were significantly higher in the pFLAG-CMV-7.1-VKORC1 transfection group than in the pFLAG-CMV-7.1 control group (P<0.01). The number of CaOx crystals in HK-2 cells incubated in fluorescently labeled CaOx monohydrate (COM) crystal medium for 48 h was 14±4 per field (100×) in the pFLAG-CMV-7.1-VKORC1 transfection group and 26±5 per field (100×) in the pFLAG-CMV-7.1 control group respectively under the laser-scanning confocal microscope. The amount of CaOx crystal aggregation and formation in the pFLAG-CMV-7.1-VKORC1 transfection group was significantly reduced as compared with the pFLAG-CMV-7.1 control group (P<0.05). The expression levels of VKORC1 mRNA and protein were significantly lower in the PGPU6/GFP/Neo-VKORC1shRNA-2 transfection group than in the PGPU6/GFP/Neo-shRNA-NC control group (P<0.05). The number of CaOx crystals in HK-2 cells incubated in fluorescently labeled COM crystal medium was 65±11 per field (100×) in the PGPU6/GFP/Neo-VKORC1shRNA-2 transfection group and 24±6 per field (100×) in the PGPU6/GFP/Neo-shRNA-NC control group respectively under the laser-scanning confocal microscope. The amount of CaOx crystal aggregation and formation in the PGPU6/GFP/Neo-VKORC1shRNA-2 transfection group was significantly increased as compared with the PGPU6/GFP/Neo-shRNA-NC control group (P<0.05). These findings suggested that the VKORC1 protein could inhibit CaOx salt crystallization, adhesion and aggregation. This research would help us to understand the mechanisms involving the interaction between crystallization and epithelial cells and the formation of CaOx.

The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.

Objective To observe the efficacy of antithrombotic treatment of acute ST-segment elevation myocardial infarction patients with failure primary percutaneous coronary intervention because of high thrombus burden,and its effect on elective percutaneous coronary intervention.Methods Eight acute ST-segment elevation myocardial infarction patients were enrolled,who suffered from failure of primary percutaneous coronary intervention because of high thrombus burden.Summarize the antithrombotic strategies in perioperative and postoperative period,the operative strategies and the follow-up coronary intervention were recorded and reviewed.Results All the patients were male and most of them had acute inferior myocardial infarction with right coronary occluded because of high thrombus burden.Four patients received thrombus aspiration and balloon dilation.One patient received thrombus aspiration and the other three patients did not receive coronary intervention.Tirofiban were given in perioperative period to all the patients.Low molecular weight heparin was given to 6 patients.Dual antiplatelet therapy was given to 6 patients (aspirin 100 mg/day plus clopidogrel 75 mg/day) and 1 patient required up-titration of aspirin to 200 mg/day.Coronary angiography were repeated (29.00 ± 23.25) days later,and the thrombus in the culprit vessels disappeared in two patients,and coronary stent implantation was performed in three patients.Conclusions The routine antithrombotic strategies play limited roles in thrombus clearance in acute ST segment elevation myocardial infarction patients with failure primary percutaneous coronary intervention because of high thrombus burden.The time for the thrombus to be totally organized and the timing of elective percutaneous coronary intervention are still uncertain and need to be further studied.

OBJECTIVE: To evaluate the therapeutical effect of surgical treatment for thoracic angioma with extraosseous extension which causes spinal cord compression and neurological dysfunction. METHODS: We retrospectively analyzed 5 cases of thoracic vertebral body angioma with extraosseous extension and spinal cord compression. The operation were performed through anterior approach to resect the involved vertebral body and intracanal angioma in 5 patients. Bone graft and internal fixation were also completed in the meantime. Two patients accepted radiotherapy for 2 periods of treatment postoperatively, and the other 3 patients didn't accept the other supportive therapy. RESULTS: The blood loss during the operation was 1000 mL to 1500 mL. All the patients recovered their neurological function rapidly after the operation. The patients were followed up for 1 to 4 years, and no patient recurred. The bone graft was solidly fused in all patients. No hardware failure occurred. CONCLUSION The surgical treatment for thoracic vertebral body and extraosseous angioma with spinal cord compression is effective, reliable, and workable. Good long-term result can be obtained.

OBJECTIVE: To analyze the clinicopathological characteristics of prostate cancer patients undertaking radical prostatectomy with single positive core biopsy, and to optimize the rational choice of therapeutic strategy. METHODS: In the study, 53 patients with single positive core prostate biopsy and treated by radical prostatectomy from January 2010 to December 2018, were analyzed retrospectively. The mean age was (69.7±6.9) years (54-81 years), the mean prostate specific antigen (PSA) level was (9.70±5.24) μg/L (1.69-25.69 μg/L), and the mean prostate volume was (50.70±28.39) mL (12.41-171.92 mL). Thirty-nine out of 54 (73.6%) patients presented Gleason score with 6, 11 patients (20.8%) had Gleason score of 7 and 3 patients (5.7%) showed Gleason score ≥8. For clinical stages, 6 out of the 53 patients (11.3%) had prostate cancer in cT1, 44 cases (83.0%) had prostate cancer in cT2, and 3 cases (5.7%) in cT3.The patients were divided into subgroups according to age, preoperative PSA level, Gleason score, percentage of tumor in single needle tissue and clinical stage, and the differences of their clinicopathological characteristics were compared. RESULTS: Postoperative Gleason score of 6, 7 and ≥8 were found in 20 cases (37.7%), 21 cases (39.6%) and 10 cases (18.9%) respectively, another 2 cases (3.8%) were pT0 prostate cancer; pathological stages of T0, T2a, T2b, T2c and T3 were found in 2 cases (3.8%), 9 cases (17.0%), 2 cases (3.8%), 29 cases (54.7%) and 11 cases (20.8%) respectively; 11 cases (20.8%) had positive surgical margin, 10 cases (18.9%) had extracapsular invasion of prostate, and 1 case (1.9%) showed seminal vesicle invasion. Forty-two cases (79.2%) had multifocal lesions and 37 cases (69.8%) presented bilateral lesion. Compared with the biopsy Gleason score, the postoperative Gleason score was downgrated in 3 cases (5.7%), unchanged in 28 cases (52.8%), and upgraded in 20 cases (37.7%), of which 2 cases (3.8%) were pT0. Compared with the clinical stage, the postoperative pathological stage decreased in 2 cases (3.8%), unchanged in 10 cases (18.9%), and upgraded in 41 cases (77.4%). According to the postoperative pathology, the patients were divided into two groups: microfocus cancer group (n=8) and non-microfocus cancer group (n=45). The difference between the two groups in the percentage of tumor in the single-needle tissue ≤5% was statistically significant (P=0.014). Other parameter diffe-rences including age, prostate volume, and preoperative prostate special antigen density (PSAD) and Gleason scores were not statistically significant (P>0.05). The method to determine the location of cancer at the apex of prostate according to biopsy results showed 41.4% (12/29) false negative rate and 50.0% (12/24) false positive rate. There was statistically significant difference between the actual cases of lymph node dissection and reserved nerve and the cases of scheme selection in theory according to the postoperative pathology (P < 0.05). CONCLUSION The proportion of single needle cancer tissue less than or equal to 5% is a predictor of prostate microfocal cancer. 37.7% cases had pathological upgrading and 77.4% cases had pathological staging upgrading. When choosing the operation scheme, such as sexual nerve reserved, lymph node dissection and apex operation skill, it is necessary to comprehensively analyze multiple factors, such as tumor risk classification, prediction factors of nomogram, multi-parameter MRI and intraoperative situation and so on.
