Objective: To investigate the effects of prostate cancer exosomes on the migration and invasion ability of stromal cells (WPMY-1), and to explore its mechanism. Methods: Exosomes in LNCaP-AI+F prostate cancer cell supernatant were isolated by ultracentrifugation and the typical structure of exosome was captured by electron microscope. The particle size distribution was analyzed by Zetaview, and Wb was used to identify the marker proteins and other proteins.After co-incubation of WPMY-1 cells and prostate cancer exosomes (40 µg/ml), laser confocal microscope was used to observe the uptake of PKH67-labeled exosomes by WPMY-1 cells; Transwell assay was used to detect the migration and invasion ability of WPMY-1 cells; qPCR was performed to detect the expression of three cancer-associated fibroblast (CAF)-related molecules (IL-8, PDGFB and MMP9) at mRNA level; and the phosphorylation of EGFR and ERK1/2 was analyzed by Wb. Results: Typical cup-shaped structure of exosomes was observed under electron microscope. The Zetaview results showed that the particle size distribution was concentrated at about 100 nm. The expression of exosome marker proteins CD63 andALIX further verified that the isolated particles were exosomes. Besides, EGFR, HER2 and SRC, which were related to the progression of prostate cancer, were also enriched in exosomes. After co-incubation, confocal microscope imaging showed a number of PKH67 labeled exosomes in recipient WPMY-1 cells. Transwell experiments showed that exosomes could significantly enhance the migration and invasion ability of WPMY-1 cells (all P<0.01). Compared with the control group, increased secretion of IL-8, PDGFB and MMP9 was observed after exosome treatment (40 µg/ml) (P<0.05 or P<0.01). Wb indicated that exosomes could promote the phosphorylation of EGFR and ERK1/2 of WPMY-1 cells (P<0.01). Conclusion: Prostate cancer cell exosomes could act on the stromal cell WPMY-1 to highly express multiple CAF-related molecules, promote the phosphorylation of EGFR and ERK1/2 and enhance the migration and invasion ability of WPMY-1 cells.

Chinese Journal of Digestive Endoscopy 2018;35(4):253-256
Objective To evaluate the magnifying endoscopy with blue laser imaging( M-BLI) for early esophageal cancers. Methods A total of 153 focal esophageal lesions detected with conventional white light endoscopy (WLE) based on changes of mucosal shape and color were enrolled in this study. Patients were examined with WLE, M-BLI, and 1. 25% Lugol′s iodine chromoendoscopy between April 2015 and December 2016. Diagnostic consistency of M-BLI and Lugol′s iodine chromoendoscopy were evaluated with pathology as a golden standard. Results Pathological diagnosis showed there were 19 lesions of esophagitis or chronic mucosal inflammation,92 of low grade intraepithelial neoplasia,and 42 high grade intraepithelial neoplasia or early cancer. Diagnostic sensitivities of WLE, M-BLI and Lugol′s iodine chromoendoscopy of screening early cancer were 66. 7%( 28/42 ), 95. 2%( 40/42 ), and 95. 2%( 40/42 ) respectively, the specificities were 57. 7%( 64/111 ), 91. 9%( 102/111 ), and 92. 8%( 103/111 ) respectively. The consistency rate between endoscopy and pathological examination were 60. 1%( 92/153 ), 92. 8%(142/153), and 93. 5%(143/153) respectively,and the Kappa values were 0. 565, 0. 891, and 0. 906 respectively. The detection rate of M-BLI was higher than that of WLE alone ( χ2 =9. 166, P=0. 002). Conclusion The diagnostic value of M-BLI for early esophageal cancer is similar to that of Lugol′s iodine chromoendoscopy. However, M-BLI is easier to operate, and superior to Lugol′s iodine staining endoscopy in the absence of iodine allergy, long operating time and patients′intolerance.

Promoter, an essential regulatory element, is widely used for metabolic engineering of industrial strains. Corynebacterium glutamicum is an important industrial workhorse to produce various amino acids. However, strong constitutive promoters that are applicable to C. glutamicum are rarely reported. In this study, we first performed a time-series transcriptome analysis of a glutamate hyper-producing strain C. glutamicum SL4 by using RNA-Seq. Overall, we picked 10 samples at different time during the fermentation process. By analyzing the time-series transcriptome data, we selected 10 candidate genes with the highest transcriptional level. These genes were all transcribed stably during the fermentation process. We subsequently cloned the promoter sequences and evaluated the promoters' strength in strain SL4 using a red fluorescent protein reporter system. To evaluate the universality of the promoters in different C. glutamicum strains, we further tested the performance of some promoters in wild type C. glutamicum strains, including ATCC 13869 and ATCC 13032. The strongest promoter was further characterized using LacZ as a reporter in all the three C. glutamicum strains. Finally, we successfully obtained three constitutive promoters with universality, PcysK, PgapA and PfumC. PcysK is the most efficient promoter among the three C. glutamicum strains. In strains SL4 and ATCC 13869, the strength of PcysK is 2-fold of the strong inducible promoter Ptac using the red fluorescent protein as a reporter and 4-fold of Ptac using LacZ as a reporter. Moreover, the strength of PcysK reaches 30%-40% of Ptac in strain ATCC 13032. The promoter PcysK is identified as a strong promoter for the first time, which can be used as an efficient biobrick for metabolic engineering of synthesis pathways in C. glutamicum.

The aim of this study is to assess the antibacterial and anti-biofilm properties of the lipid extract from Mantidis ootheca against the gentamycin resistant Pseudomonas aeruginosa. The chemical composition of the lipid extract and its relative proportion were determined using the technique of gas chromatography coupled with mass spectrometry (GC-MS). Antibacterial susceptibility tests were performed using a disc diffusion assay and the minimum inhibition concentration (MIC) was determined by way of the agar dilution method. The anti-biofilm test was carried out with crystal violet staining and scanning electron microscopy (SEM). There were 16 compounds detected, and the most abundant components were sesquiterpenoids, monoterpenes, and trace aromatic compounds. The MIC for P. aeruginosa was 4 mg/ml and the eradication effect on preformed biofilms was established and compared with a ciprofloxacin control. The results of our study indicated that a lipid extract from M. ootheca could be used as a topical and antibacterial agent with anti-biofilm activity in the future.

OBJECTIVETo observe the clinical effects differences and partial mechanism for chronic nonbacterial prostatitis (CNP) among drug oil moxibustion, simple moxibustion, and conventional western medicine.
METHODSA total of 120 patients who met the criteria of inclusion were randomly assigned into a drug oil moxibustion group, a moxibustion group and a western medication group, 40 cases in each one. Moxibustion was used at Guanyuan (CV 4), Zhongji (CV 3), Qihai (CV 6) and bilateral Yinlingquan (SP 9), Sanyinjiao (SP 6), Shenshu (BL 23), Mingmen (GV 4), Pangguangshu (BL 28), Ciliao (BL 32), and Zhibian (BL 54), etc. The same moxibustion was used at the same acupoints in the drug oil moxibustion group after external application of medicated oil. Thirty min treatment was used once a day in alternated abdomen and back. In the western medication group, oral tamsulosin hydrochloride capsules were applied once a day, one capsule at a time. All the treatment was given for 30 days. Chronic prostatitis symptom index from National Institutes for Health (NIH-CPSI), the contents of Zinc (Zn) and C-reactive protein (CRP), as well as the number of white blood cells (WBC) and density of lecithin bodies were observed before and after treatment and 1 month after treatment. The effects were evaluated after treatment.
RESULTSAfter treatment, the total effective rate of the drug oil moxibustion group was 90.0% (36/40), which was significantly higher than 72.5% (29/40) of the moxibustion group and 62.5% (25/40) of the western medication group (both<0.05). After treatment and at follow-up in the three groups, the NIH-CPSI scores were lower than those before treatment (all<0.05), and those in the drug oil moxibustion group were lower than the results in the moxibustion group and the western medication group (all<0.05). The contents of Zn in the three groups were higher than those before treatment (all<0.05), with better results in the drug oil moxibustion group (all<0.05), and higher Zn contents in the moxibustion group compared with those in the western medication group (both<0.05). The CRP levels were lower than those before treatment (all<0.05), and those in the drug oil moxibustion group were better than those in the moxibustion group and western medication group (all<0.05). The CRP contents in the moxibustion group were lower than those in the western medication group (both<0.05). The number of WBC were lower than those before treatment (all<0.05), with better results in the drug oil moxibustion group (all<0.05). The concentrations of lecithin were higher than those before treatment (all<0.05), with better results in the drug oil moxibustion group (all<0.05).
CONCLUSIONSThe clinical effect of drug oil moxibustion is better than those of simple moxibustion and western medicine, which has advantages in improving clinical symptoms, Zn, the density of lecithin body and decreasing CRP content and the number of WBC.
