Prostate cancer (PCa) exhibits epidemiological and molecular heterogeneity. Despite extensive studies of its phenotypic and genetic properties in Western populations, its molecular basis is not clear in Chinese patients. To determine critical molecular characteristics and explore correlations between genomic markers and clinical parameters in Chinese populations, we applied an integrative genetic/transcriptomic assay that combines targeted next-generation sequencing and quantitative real-time PCR (qRT-PCR) on samples from 46 Chinese patients with PCa. Lysine (K)-specific methyltransferase 2D (KMT2D), zinc finger homeobox 3 (ZFHX3), A-kinase anchoring protein 9 (AKAP9), and GLI family zinc finger 1 (GLI1) were frequently mutated in our cohort. Moreover, a clinicopathological analysis showed that RB transcriptional corepressor 1 (RB1) deletion was common in patients with a high risk of disease progression. Remarkably, four genomic events, MYC proto-oncogene (MYC) amplification, RB1 deletion, APC regulator of WNT signaling pathway (APC) mutation or deletion, and cyclin-dependent kinase 12 (CDK12) mutation, were correlated with poor disease-free survival. In addition, a close link between KMT2D expression and the androgen receptor (AR) signaling pathway was observed both in our cohort and in The Cancer Genome Atlas Prostate Adenocarcinoma (TCGA-PRAD) data. In summary, our results demonstrate the feasibility and benefits of integrative molecular characterization of PCa samples in disease pathology research and personalized medicine.

OBJECTIVETo analyze the advantages of spatial measurement of anatomical parameters in a 3D model in surgical planning for laparoscopic partial nephrectomy (LPN).

METHODSFrom February, 2016 to October, 2017, 37 patients diagnosed with T1 renal mass underwent LPN based on 3D reconstruction after enhanced CT scanning using the Uromedix-3D system (group A), and another 38 patients received LPN with conventional CT planning (group B). The anatomical parameters were measured in the reconstructed 3D model and the demographic data, surgical outcome and postoperative data were compared between the two groups.

RESULTSIn group A, the average time for 3D model reconstruction was (29.3∓9.7) min; the length, width and depth of the renal defect in 3D model were 3.2∓1.1 cm, 2.6∓0.9 cm and 1.7∓0.7 cm, respectively; The distance of the tumor from the collecting system was 3.8∓2.2 mm; The mean R.E.N.A.L score of the patients was 7∓1.5, and 3 patients had accessory renal artery and 2 had early branching of the renal artery. LPNs were completed via the retroperitoneal approach in all the 75 patients without conversion to open or total nephrectomy. Group A and group B showed significant differences in warm ischemic time (26.7∓6.4 vs 31.9∓7.0 min), tumor-excision time (8.4∓2.6 vs 10.4∓2.8 min), renal defect suture time (18.3∓3.9 vs 21.5∓3.4 min), 24-h volume of retroperitoneal drainage (88.6∓40.2 vs 134.3∓58.3 mL) and 48-h volume of retroperitoneal drainage (127.9∓54.5 vs 198.1∓86.3 mL), but not in the demographic data, operation time, intraoperative blood loss or postoperative hospital stay.

CONCLUSIONS3D reconstruction of the renal masses can be completed efficiently and accurately using this system. Compared with conventional CT-based measurement, 3D spatial measurement of the anatomical structures helps to increase the precision in the performance of LPN and reduce the warm ischemia time.

Klinefelter syndrome (KS) is the set of symptoms that result from the presence of an extra X chromosome in males. Postnatal population-based KS screening will enable timely diagnosis of this common chromosomal disease, providing the opportunity for early intervention and therapy at the time point when they are most effective and may prevent later symptoms or complications. Therefore, through this study, we introduced a simple high-resolution melting (HRM) assay for KS screening and evaluated its clinical sensitivity and specificity in three medical centers using 1373 clinical blood samples. The HRM assay utilized a single primer pair to simultaneously amplify specific regions in zinc finger protein, X-linked (ZFX) and zinc finger protein, Y-linked (ZFY). In cases of KS, the ratios of ZFX/ZFY are altered compared to those in normal males. As a result, the specific melting profiles differ and can be differentiated during data analysis. This HRM assay displayed high analytical specificity over a wide range of template DNA amounts (5 ng-50 ng) and reproducibility, high resolution for detecting KS mosaicism, and high clinical sensitivity (100%) and specificity (98.1%). Moreover, the HRM assay was rapid (2 h per run), inexpensive (0.2 USD per sample), easy to perform and automatic, and compatible with both whole blood samples and dried blood spots. Therefore, this HRM assay is an ideal postnatal population-based KS screening tool that can be used for different age groups.

Araloside A is one of the main active ingredients of Aralia taibaiensis. In this study, HPLC-MS/MS analysis method of araloside A in the main organs of SD rats was established. At the same time, the content of araloside A in the main organs (heart, liver, spleen, lung, kidney, brain) after oral administration with araloside A (50 mg•kg⁻¹) were determined to explore the tissue distribution characteristics of araloside A in vivo. The results showed that the methodological study of araloside A in the main organs of SD rats met the requirements, araloside A distributed in heart, liver, spleen, lung, kidney and brain tissues reached peak at 1 h or 2 h after oral administration with 50 mg•kg-1.The distributions of araloside A at different time points after administration were distinct as follows： the content of araloside A at 20 min：liver>heart>spleen>lung>kidney>brain; the content of araloside A at 1 h： liver>spleen>kidney>lung>heart>brain; the content of araloside A at 2 h： liver>kidney>heart>spleen>lung>brain; the content of araloside A at 4 h： kidney>liver>spleen>heart>lung>brain; the content of araloside A at 8 h： spleen>heart>liver>kidney>lung>brain. Therefore, araloside A was mainly distributed in liver tissue, which had a certain correlation with the common use of Aralia taibaiensis in the treatment of hepatic disease. In addition, araloside A shows a low content but an obvious distribution in brain tissues, which indicates that the drug can pass through blood-brain barrier, and provides the basis for the study of araloside A in brain tissue.

Due to the particularity of ginseng cultivation, the soil fertility of cultivated ginseng is seriously depleted, so that the cultivated ginseng land can not be reused in the short term, and the land area available for cultivating ginseng becomes less and less with the growth of ginseng cultivation time. Therefore, in order to effectively manage ginseng cultivation, and achieve the sustainable use of ginseng land, it is necessary to obtain accurate information on the distribution of ginseng planting space. In this study, the object-oriented classification method based on rule set was used to extract ginseng planting area based on the ZY-3 satellite data in Fusong county, Jilin province. Firstly, multi-scale segmentation of ZY-3 remote sensing image in the study area was made, and the optimal segmentation scale was determined on the basis of multi-scale segmentation results. Secondly, a spectral curve according to the different feature type samples was generated. The similarities and differences between ginseng plot and other types of surface features were analyzed, and a rule set based on the results of spectral analysis was established to achieve the final extraction. The results show that the object-oriented classification method based on rule set can effectively extract the ginseng planting plots in the study area, and solve the problem that the extraction result is broken compared with the traditional pixel-based classification method.

Objective: To investigate the impact of discontinued dual antiplatelet therapy(DAPT) of aspirin combining clopidogrel within 5 days on peri-operative bleeding in patients with coronary artery bypass grafting (CABG). Methods: A total of 2012 patients with off-pump CABG were retrospectively enrolled in our study including 1506 male and the mean age was at 61.92 years. All patients received regular DAPT previously and discontinued the medication≤5 days due to emergency or prior limited CABG. Based on the days from discontinued DAPT to operation, the patients were divided into 6 groups: 0-day group, n=220, 1-day group, n=240, 2-day group, n=360, 3-day group, n=332, 4-day group, n=428 and 5-day group, n=432. Relationships between risk factors of bleeding and discontinued DAPT time were studied. Results: Bleeding was defined by BARC (bleeding academic research consortium) standard. The incidences of bleeding events in 0-day group, 1-day group, 2-day group, 3-day group, 4-day group and 5-day group showed a decreasing trend as 29.1%, 24.6%,19.4%, 13.0%, 14.5% and 13.0% respectively, P<0.01. Post-operative chest drainage volume≥2L within 24h (P=0.13) and intracranial bleeding (P=0.60) had no obvious tendency changes; occurrence rates of 48h peri-operative transfusion≥5 U whole blood or red blood cells (P<0.01) and re-operation(P<0.01) had a decreasing trend by prolonged time of discontinued medication. The minor endpoint events were similar. Compared to (3-5) days discontinued medication, the patients with (0-2) days discontinued DAPT were with the higher incidences of overall bleeding, re-operation and 5U transfusion, the differences had statistical meaning. Conclusion: The incidence of bleeding presented a decreasing trend by prolonged time of discontinued DAPT before CABG;transfusion and re-operation had the statistical meaning for bleeding. Discontinued medication less than 3 days may increase bleeding events and therefore, in high risk patients, prior CABG discontinued medication should be more than 3 days.

Objective To investigate the biofilm formation rate of Candida albicans strain and its sensitivity to antifungal agents.Methods Candida albicans strains were isolated from 165 patients with vulvovaginal candidiasis (VVC) or recurrent vulvovaginal candidiasis (RVVC) in our hospital.The sensitivity of C.albicans strains to antifungal agents was evaluated by drug sensitivity test.And C54 strains for subsequent experiments in vivo and vitro were selected.Biofilms of single microbe or polymicrobial combination were induced in vitro,and their minimal inhibitory concentration (MIC) values were determined in free and biofilm patterns,respectively.C.albicans and mixed microbe suspensions were injected into mice to establish a model of VVC.Using ELIASA,OD595 values were determined to observe biofilm growth rates across groups.Results The largest number of itraconazole-resistant on C.albicans strains (4.20％).MIC values of all groups were higher in a free pattern than in a biofilm pattern.The polymicrobial biofilms formed by co-culture of fugal and bacterial strains were markedly resistant to various antifungal agents.Mter induction in the biofilm pattern,for C54 + Escherichia coli group,MIC values of resistance to amphotericin B,itraconazole,5-flucytosine and fluconazole were 512,＞256,＞512,and ＞ 1024 μg · mL-1;for C54 + Streptococcus agalactiae group,MIC values of resistance to above antifungal agents were ＞512,＞256,＞512,and ＞ 1024 μg · mL-1.The biofilm formation rate was significantly higher in vaginal samples isolated from the mice who were injected with mixed microbe suspension than those who were injected with standard C.albicans suspension (P ＜ 0.05).For ATCC14053 group,OD595 values were 0.20 ± 0.11,0.24 ± 0.024,0.25 ± 0.06 at 24,48 and 72 h,respectively;for C54 + E.coli group,OD595 values were 0.69 ±0.88,0.79 ±0.65,1.10 ±0.64 respectively;for C54 +S.agalactiae group,OD595 values were 0.68 ±0.42,0.81 ± 0.77,1.10 ± 0.10,respectively.Conclusion Polymicrobial biofilm formation can improve the biofilm formation rate of C.albicans and its resistance to antifungal agents and will enhance vaginal injury in patients with RVVC.

OBJECTIVETo investigate the effects of silencing ADP-ribosylation factor 6 (Arf6) on the proliferation, migration, and invasion of prostate cancer cell line PC-3 and the possible molecular mechanisms.

METHODSThree Arf6-specific small interfering RNA (siRNA) were transfected into cultured prostate cancer cell line PC-3. Arf6 expression was examined by real-time PCR and Western blotting. MTT assay, wound healing assay, and Transwell migration and invasion assay were used to observe the effect of Arf6 silencing on the proliferation, migration, and invasion ability of PC-3 cells. The levels of phosphorylated extracellular signal-regulated kinase 1/2 (p-ERK1/2), ERK1/2, p-AKT, AKT and Rac1 were detected by Western blotting.

RESULTSTransfection of siRNA-3 resulted in significantly decreased Arf6 mRNA and protein expression with inhibition rates of (91.88±3.13)% and (86.37±0.57)%, respectively. Arf6 silencing by siRNA-3 markedly suppressed the proliferation, migration and invasion of PC-3 cells and reduced the expression levels of p-ERK1/2 and Rac1.

CONCLUSIONSilencing of Arf6 efficiently inhibits the proliferation, migration, and invasion of PC-3 cells in vitro, and the underlying mechanisms may involve the down-regulation of p-ERK1/2 and Rac1.
