Objective To describe the CSP genotypic profile in clinical isolates of Aspergillus fumigates from different regions of China,and to investigate if there is a difference in antifungal susceptibility among A.fumigates of different CSP genotypes and from different regions.Methods Totally,112 A.fumigates strains clinically isolated from Fujian,Shanghai,Hebei and Beijing were included in this study,and identified according to macro-and micro-morphological characters,growth temperature and β-tubulin sequence.Classic A.fumigatus strains were typed according to CSP gene sequence.The minimal inhibitory concentrations (MICs) of voriconazole,itraconazole and amphotericin B to A.fumigates were determined in accordance with the National Committee for Clinical Laboratory Standards (NCCLS) M38-A protocol.Results All the strains were identified as classic A.fumigates,and fall into 11 CSP genotypes.The most common genotypes were t04A (n =32),t03 (n =17) and t01 (n =24) in all the strains,tl0,t04A and t01 in Fujian,t04A and t01 in Shanghai,t01,t03 and t04A in Hebei,t02,t04A,t01and t03 in Beijing.One A.fumigatus strain was identified as a new CSP type t25 in Fujian,which showed no obvious difference in morphology,growth rate or appropriate growth temperature from the other CSP genotypes of A.fumigatus strains.No statistical difference was found in the susceptibility to amphotericin B,itraconazole or fluconazole among different genotypes of A.fumigates,whereas the MICs of itraconazole were significantly lower in A.fumigates isolates from Fujian than in those from the other three regions.Conclusions The CSP genotypic profile of A.fumigates varies in clinical isolates from different regions.No significant difference is observed in the susceptibility to amphotericin B,itraconazole or fluconazole among different CSP genotypes of A.fumigates,but the susceptibility to itraconazole is somewhat different between A.fumigates strains from different regions.

Objective:To systematically evaluate the effects of "Internet+" nursing intervention mode on negative emotion and pregnancy outcome of infertility patients.Methods:PubMed, Cochrane Library, Web of Science, Embase, China National Knowledge Infrastructure, Wanfang, VIP and Chinese Biomedical Literature Database were searched to collect randomized controlled tria related to the effects of "Internet+" nursing interventions on patients with infertility from the inception to August 10th 2023. Two researchers conducted independent quality evaluation, evidence extraction and summary of the literature. Meta-analysis was performed by RevMan 5.4 software.Results:A total of 11 studies were included with a total of 1 596 patients. The Meta-analysis showed that nursing interventions based on "Internet+" significantly improved the anxiety of patients with infertility ( SMD=-1.09, 95% CI-1.76- -0.43, P< 0.01), depression ( SMD=-0.98, 95% CI-1.42- -0.54, P<0.01), biochemical pregnancy rate ( OR=1.67, 95% CI 1.14- 2.44, P<0.01), clinical pregnancy rate ( OR=1.83, 95% CI 1.22- 2.73, P<0.01), but no effect on infertility pressure ( MD=-3.81, 95% CI-15.10- 7.47, P>0.05). Conclusions:The interventions based on "Internet+" can effectively improve anxiety, depression and pregnancy outcome, but there is no adequate evidence of a reduction on infertility stress in patients.

Polycystic ovary syndrome (PCOS) is a common reproductive endocrine and metabolic disease, and its pathogenesis is closely related to inflammation, insulin resistance, and metabolic disorders. Bilirubin is the final product of the destruction and degradation of senescent red blood cells in the body. In addition, bilirubin can be not only used to evaluate liver function damage and cytotoxicity, but also can anti-inflammatory, antioxidant, alleviate metabolic disorders, etc. Recently, studies have found a certain correlation between low levels of bilirubin and PCOS: the level of bilirubin in patients with PCOS is low, and the anti-inflammatory and antioxidant properties of bilirubin may play a protective role in the pathogenesis of PCOS.
