Objective To establish a method for detecting Aspergillus spp.by Loop-mediated isothermal amplification.Methods Aspergillus spp.specific primers were designed from the relative conservation region of the published sequence of 28S rRNA genes of A.fumigatus (GenBank accession number AY660917),A.terreus (GenBank accession number AF454183),A.flavus (GenBank accession number AF454158),and A.niger (GenBank accession number AF454169).Genomic DNA were extracted from Aspergillus standard strains,clinical control strains and clinical samples,and amplified by LAMP.The amplified results could be read with the naked eye by the coloring effect of fluorescent nucleotide dye without the DNA electrophoresis.Approximately 103 each Aspergillus conidia suspension was added to the serum from healthy volunteers,and detected these simulative clinical samples bv LAMP assay.Results The LAMP and PCR assays obtained positive results for all four Aspergillus species and 8 simulative clinical samples (double samples for each Aspergillus species) including 103 conidia,but negative in the remaining 15 non-Aspergillus species,human total blood genomic DNA,30 clinical serum samples infected with non-Aspergillus and 10 healthy volunteers.The LAMP assay had a minimum detection of 0.05-0.5pg,by means of detect different levels of 500,50,5,0.5,0.05 pg template in each reaction tube.Conclusion The results confirm that LAMP is a simple,rapid,sensitive and specific method,and can be used for detection of Aspergillus strains in clinical and environmental specimens.

Objective:To investigate the effect of transurethral plasma enucleation of prostate with bladder neck and prostatic apex urethral mucosa preservation on the incidence of retrograde ejaculation after surgery.Methods:The clinical data of 77 patients with benign prostatic hyperplasia (BPH) admitted to Jinhua people's Hospital from January 2018 to June 2020 were retrospectively analyzed. The ages of the two groups [(62.06±2.01)years old and (62.36 ± 2.12)years old] were comparable. There were no significant differences between the groups( P>0.05) in term of the prostate volume (72.91±17.57) ml vs. (68.07±17.28)ml, Q max [(7.33±2.02)ml/s vs. (7.79±2.09)ml/s)], and IPSS (25.51±5.66) vs.(25.17±4.90). The conventional operation group was treated with " trefoil" enucleation of prostate. The modified operation group underwent the following three improved techniques. Firstly, the anterior mucosa of the verumontanum was cut 1.5 cm away from the medial surface of the verumontanum to prevent the external sphincter injury. Secondly, part of the prostate tissue was retained by exceeding the verumontanum when cutting off the bilateral lobes. Thirdly, the middle lobe of the prostate was bluntly stripped to the bladder neck with the sheath of the electroscope in order to protect the transverse muscle fibers as well as the integrity of the bladder neck. The outcome and the ejaculation function of the two groups were analyzed. Results:There was no significant difference in operation time [(66.74±9.29)min vs. (71.29±15.32) min], catheter indwelling duration [(5.31±0.76)d vs.(5.00±1.06)d], and hospital stay [(7.57±0.88) d vs. (7.17±1.45)d] between the two groups ( P>0.05) after more than 6 months of follow-up. According to IIEF score, mild erectile dysfunction occurred in both groups, with the incidence rate of 20.7%(6/29) and 13.5%(5/37) respectively, and there was no significant difference between the two groups ( P>0.05). The postoperative maximum urinary flow rate (Q max) [(23.51±4.25) ml/s vs.(24.05±3.81)ml/s] and IPSS score (6.46±2.72 vs. 6.55±2.99) was significantly different from that before the operation ( P<0.05). However, there was no significant difference between the two groups ( P>0.05). The incidence of retrograde ejaculation in conventional operation group and modified operation group was 23/35(65.7%) and 13/42(31.0%), and the difference was statistically significant ( P<0.05). Immediate urinary continence were 24/35(68.6%) and 36/42(85.7%) in the conventional operation group and the modified operation group respectively, and there was no significant difference between the two groups( P>0.05). After 6 months of follow-up, urinary continence in both groups was 100.0%. Conclusions:Transurethral plasmakinetic enucleation of the prostate with the preservation of bladder neck and urethral mucosa of prostate apex is the same effective as conventional operation in the treatment of benign prostatic hyperplasia, but the incidence of retrograde ejaculation after operation is significantly reduced, which is suitable for those patients who desire to retain their ejaculation function.
