OBJECTIVE: To investigate the clinical effect and adverse reactions of dapoxetine hydrochloride versus paroxetine in the treatment of primary premature ejaculation by cross-comparison. METHODS: Based on the clinic-visit time, we equally randomized 148 patients with primary premature ejaculation into groups A and B for a cross-comparison test, the former treated with paroxetine at 20 mg once nightly and the latter with dapoxetine hydrochloride at 30 mg on demand, both for 6 successive weeks, during which we observed the therapeutic effects and adverse reactions. Following 4 weeks of drug discontinuance, we administered dapoxetine hydrochloride at 30 mg on demand for group A and paroxetine at 20 mg once nightly for group B, both for another 6 successive weeks, followed by observation and comparison of the therapeutic effects and adverse reactions. RESULTS: There were no statistically significant differences in the initial characteristics of the two groups of patients (P > 0.05). Compared with the baseline, the mean intra-vaginal ejaculation latency time (IELT) was dramatically improved after treatment in both groups A (4.43 min) and B (7.12 min), increased by 3.99% and 6.72%, respectively (P<0.001). The patients treated with paroxetine showed significantly longer IELT than those taking dapoxetine hydrochloride in both groups (P<0.001). Findings of the Premature Ejaculation Profile (PEP) and spouses' conditions indicated significant improvement after treatment in the average scores of the four indicators of PEP, that is, perceived control over ejaculation, ejaculation-related personal distress, satisfaction with sexual intercourse and ejaculation-related interpersonal difficulty, as well as in the overall experience and partner's satisfaction and orgasm frequency. Adverse reactions to medication were found in 20.8% of the cases in group A and 9.7% in group B, but none was serious. Preference survey following drug withdrawal revealed a preference for paroxetine (61.9%) over dapoxetine (26.8%), and that only a few of the patients thought of the two drugs as comparable or both ineffective. CONCLUSION In term of overall effectiveness, paroxetine was superior to dapoxetine in the treatment of primary premature ejaculation. And the patients obviously preferred the former to the latter, which might be partly attributed to the higher price of dapoxetine.

Glycoengineering was carried out in the mammalian cell line CHO for the production of pro-tein-based drugs.Firstly,the genome sequence of the Rosa26 locus of CHO cells was determined,the gRNA sequences were designed,and the landing pad was integrated into the Rosa26 locus of CHO cells by CRISPR/Cas9 technology.Three targeting vectors co-expressed by glycosyltransferases,which are β-1,4 galactosyltransferase(B4GALT1),α-2,6-sialyltransferase 1(ST6GAL1)and N-acetaminoglycosyl-transferase Ⅲ(GnT Ⅲ),were constructed by overlapping PCR and seamless ligation technology,and the three glycosyltransferase genes were integrated into the CHO Rosa26 locus by Cre enzyme-mediated cassette exchange technology.PCR confirmed that three glycosyltransferases had been successfully site-directed integrated into the Rosa26 site.The mRNA expression levels of the three glycosyltransferases were more than 50 000-fold by qRT-PCR,and the protein expression levels of the three glycosyltrans-ferases were more than 4-fold via western blotting(P＜0.001).A CHO-engineered cell line with three glycosyltransferases integrated into Rosa26 site was successfully constructed.

Chest CT pulmonary angiography (CTPA) has certain auxiliary diagnostic value for the clinical diagnosis of invasive pulmonary aspergillosis (IPA) . Three patients with hematological malignancies were reported, including 2 ones after allogeneic hematopoietic stem cell transplantation and 1 ones after chemotherapy for refractory recurrent leukemia. Each patient was treated with antibiotics for at least 48 hours after the onset of fever, they all underwent chest high-resolution CT (HRCT) scans without fever resolution. CT revealed at least one dense pulmonary consolidation shadow with a diameter greater than 10 mm, and subsequently a CTPA examination was performed to observe the effect of CTPA imaging signs for the diagnosis of IPA. There were 2 patients with positive vascular occlusion sign (VOS) and 1 patient with negative VOS detected by CTPA. Among them, 2 patients with positive VOS were diagnosed with possible IPA and received with diagnosis-driven antifungal treatment, which improved their conditions. One patient with negative VOS sign was diagnosed with diffuse large B-cell lymphoma involving the lungs. After receiving anti-lymphoma treatment, the lesions significantly reduced in size. The vascular occlusion sign detected by CTPA is relatively characteristic. For high-risk IPA patients, it helps to improve the specificity of imaging diagnosis and guide clinical treatment decisions.

With prominent medicinal value, Gelsemium elegans has been overexploited, resulting in the reduction of the wild resource. As a result, artificial cultivation turns out to be a solution. However, this medicinal species is intolerant to low temperature, and thus genes responding to the low temperature are important for the cultivation of this species. Based on the transcriptome database of G. elegans at 4 ℃, 29 differentially expressed GeERF genes were identified. Bioinformatics analysis of 21 GeERF gene sequences with intact open reading frames showed that 12 and 9 of the GeERF proteins respectively clustered in DREB subgroup and ERF subgroup. GeDREB1 A-1-GeERF6 B-1, with molecular weight of 23.78-50.96 kDa and length of 212-459 aa, were all predicted to be hydrophilic and in nucleus. Furthermore, the full-length cDNA sequence of GeERF2B-1 was cloned from the leaves of G. elegans. Subcellular localization suggested that GeERF2B-1 was located in the nucleus. According to the quantitative reverse-transcription PCR(qRT-PCR), GeERF2B-1 showed constitutive expression in roots, stems, and leaves of G. elegans, and the expression was the highest in roots. In terms of the response to 4 ℃ treatment, the expression of GeERF2B-1 was significantly higher than that in the control and peaked at 12 h, suggesting a positive response to low temperature. This study lays a scientific basis for the functional study of GeERF transcription factors and provides gene resources for the improvement of stress resistance of G. elegans.

BACKGROUND: Recent cardiovascular outcome trials (CVOTs) changed the therapeutic strategy of guidelines for type 2 diabetes. We compared the characteristics of patients from real-world hospital settings with those of participants in recent pragmatic randomized trials. METHODS: This electronic medical record (EMR)-based retrospective observational study investigated the data of patients with diabetes from inpatient and outpatient settings in West China Hospital of Sichuan University from January 1, 2011, to June 30, 2019. We identified patients meeting the inclusion criteria of a pragmatic randomized trial (EMPA-REG OUTCOME) based on EMRs and compared their baseline characteristics with those of the trial participants. The cutoff for the clinical significance of each characteristic was set as its minimal clinically important difference based on expert consultation. RESULTS: We included 48,257 inpatients and 36,857 outpatients with diabetes and found that 8389 (17.4%) inpatients and 2646 (7.2%) outpatients met the inclusion criteria for the EMPA-REG OUTCOME trial. Compared with the trial population, the real-world inpatients meeting the eligibility criteria of the EMPA-REG OUTCOME had similar age, blood pressure, and lipid profiles but comprised of fewer males, metformin users, anti-hypertensive drug users, and aspirin users, and had a lower body mass index. The group of outpatients meeting the eligibility criteria had fewer males, similar age, fewer metformin users, fewer insulin users, fewer anti-hypertensive drug users, and fewer aspirin users compared with the trial population. CONCLUSIONS The trial population in EMPA-REG OUTCOME represents only a small portion of patients with diabetes from the inpatient and outpatient departments of a Chinese tertiary medical center. Evidence localization in different clinical settings and validation are essential to enabling extrapolation of the results from CVOTs in patients with diabetes to Chinese clinical practice.
