This article was aimed to study the species identification capability of psbA-trnH among Guanzhong herbs from Dryopteri. The nucleotide sequence information of psbA-trnH region was abstracted using standardized manners from 9 Dryopteri species (19 samples). The identification efficiency of psbA-trnH was analyzed based on TaxonGap among both tested materials (9 species, 19 samples) and tested materials plus GenBank data (17 species, 44 samples in total). The results showed that with the expanded species range, the discriminative efficiency of psbA-trnH de-clined from 100% (9/9) to 82.4% (14/17), while the proportion of within-specific heterogeneity larger than between-specific separability increased from 11.1% (1/9) to 52.9% (9/17). It was concluded that psbA-trnH can be recom-mended as the valuable barcode for homonym distinguishment among Guanzhong herbs, with attention of adequate sampling within species.

Objective To assess the safety and efficacy of stent-assisted coil embolization for acutely ruptured wide-necked intracranial aneurysms. Methods We retrospectively reviewed 192 wide-necked intracranial aneurysms in 178 patients. The efficacy and peri-procedure complications of stent-assisted embolization were compared between rup?ture aneurysms and unrupture aneurysms. Results Stent was successfully implanted in 78 rupture aneurysms and 114 un?rupture aneurysms. There was statistically significant difference between rupture aneurysms and unrupture aneurysms groups in rate of poor prognosis on discharge ( 23.1%vs. 5%,χ2=12.726, P<0.001) but not in the peri-procedure compli?cations rate (14.1%vs. 6.1%,χ2=3.456,P>0.05)nor in the rate of mortality and permanent disability (8.9%vs. 6.1%,χ2=0.475, P>0.05). Angiograms at 14.7 months of follow-up did not reveal any significant difference between rupture aneu?rysms and unrupture aneurysms groups in aneurysm complete occlusion (74.1%vs. 70.6%,χ2=0.197,P>0.05), recana?lization (10.3%vs. 9.4%,χ2=0.034,P>0.05)and in-stent stenosis (3.4%vs. 4.7%,χ2=0.136,P>0.05). Conclusion Stent-assisted coil embolization for acutely rupture wide-necked intracranial aneurysms can prevent recurrence effective?ly and can achieve high complete occlusion rate in long term follow-up. However, its procedure related complications and mortality is higher in rupture aneurysms than in unrupture aneurysms, which indicates that a caution is needed to conduct stent-assisted coil embolization in rupture aneurysms.

AIM: To observe the effect of exogenous androgen responsive element decoy on the promoter of prostate specific antigen (PSA) and the growth of LNCaP cells for searching the possibility of gene therapy for prostate cancer. METHODS: Firstly, pGL3 - PSA luciferase expression vector containing 640bp - promoter fragment of PSA gene was constructed. Then, a 23 -mer phosphorothioated ARE decoy based on the deduced ARE sequence at the promoter region of PSA gene was synthesized. pGL3 - PSA and ARE decoy DNA were cotransfected into PC3 - M cell by lipofectamineTM 2000. Through detecting the activity of luciferase, the effect of ARE decoy on the promoter of PSA was studied. Then the ARE decoy DNA was transfected into LNCaP cells. The effect of decoy DNA on the proliferation of LNCaP cells was examined by using MTT assay. The effects of apoptosis were detected by phase contrast microscopy, DNA agrose gel electrophoresis and flow cytometry. Meanwhile, the nuclear extract was prepared from LNCaP cells and DNA - protein interactions were examined by electrophoretic mobility shift assay (EMSA). RESULTS: The reporter assay showed that the aetivity of luciferase was significantly reduced in the ARE decoy - transfected cells, bnt not in the cells transfected with the control decoy. EMSA demonstrated specific binding of the ARE decoy to androgen receptor. The growth of LNCaP was remarkably inhibited and apoptotic morphological changes as well as DNA fragmentation were observed in the ARE decoy- transfected cells. The rate of apoptosis was 22.4% detected by FCM. CONCLUSION: The ARE decoy is capable of inhibiting the promoter of PSA gene and inducing the apoptosis in prostate cancer cells. It may become a potential therapeutic tool for prostate cancers.

Objective:To investigate the prognosis of cT3 and the subgroups of low rectal cancer patients who underwent neoadju-vant chemoradiotherapy (CRT) and evaluate whether all patients with cT3 low rectal cancer should undergo CRT. Methods:A total of 223 patients with cT3 low rectal cancer treated in the Department of Colorectal Surgery of Fujian Medical University Union Hospital from January 2008 to December 2012 were divided into neoadjuvant chemoradiotherapy group (CRT group) (115 cases) and no neoad-juvant chemoradiotherapy group (nCRT group) (108 cases) according to whether the patients underwent CRT. Afterward, the patients were retrospectively divided into three subgroups (mrT3a, mrT3b, and mrT3c) according to the proposed criteria of the Radiologic Soci-ety of North America (RSNA) by measuring the depth of mesorectal invasion (DMI) (DMI<5, DMI=5-10, and DMI>10 mm). The prog-noses of the two groups and their subgroups were compared. Results:The CRT and nCRT groups revealed no significant differences in the 3-year disease-free survival rate and the local recurrence rate for all the mrT3 patients (78.2%vs. 71.9%, P=0.608;4.4%vs. 8.5%, P=0.120) and mrT3a patients (82.4%vs. 81.8%, P=0.837;5.8%vs. 5.9%, P=0.658). On the contrary, for the mrT3b patients, the CRT and nCRT groups revealed significant differences in the 3-year disease-free survival rate (84.4%vs. 42.4%, P=0.032) and local recurrence rate (0.0%vs. 18.2%, P=0.014). For the mrT3b,c patients, the CRT and nCRT groups revealed no significant difference in the 3-year dis-ease-free survival rate (72.8%vs. 42.4%, P=0.060) but revealed a significant difference in the local recurrence rate (2.4%vs. 18.2%, P=0.021). COX regression analysis was utilized for 3-year disease-free survival, DMI and circumferential resection margin (CRM) were significant in the univariate analysis. Additionally, the multivariate analysis indicated that CRM is an independent impact factor (OR=2.249, CI 1.067-4.742, P=0.033). Conclusion:CRT can improve the prognosis of patients with mrT3b,c low rectal cancer but may not significantly influence the prognosis of patients with mrT3a and CRM-negative low rectal cancer;surgical treatment can be performed in these patients without CRT.
