(±)-Talapyrones A-F (1-6), six pairs of dimeric polyketide enantiomers featuring unusual 6/6/6 and 6/6/6/5 ring systems, were isolated from the fungus Talaromyces adpressus. Their structures were determined by spectroscopic analysis and HR-ESI-MS data, and their absolute configurations were elucidated using a modified Mosher's method and electronic circular dichroism (ECD) calculations. (±)-Talapyrones A-F (1-6) possess a 6/6/6 tricyclic skeleton, presumably formed through a Michael addition reaction between one molecule of α-pyrone derivative and one molecule of C8 poly-β-keto chain. In addition, compounds 2/3 and 4/5 are two pairs of C-18 epimers, respectively. Putative biosynthetic pathways of 1-6 were discussed.

Viruses constitute a significant group of pathogens that have caused numerous fatalities and substantial economic losses in recent years, particularly with the emergence of coronaviruses. While the impact of SARS-CoV-2 appears to be diminishing in daily life, only a limited number of drugs have received approval or emergency use authorization for its treatment. Given the high mutation rate of viral genomes, host-directed agents (HDAs) have emerged as a preferred choice due to their broad applicability and lasting effectiveness. In contrast to direct-acting antivirals (DAAs), HDAs offer several advantages, including broad-spectrum antiviral activities, potential efficacy against future emerging viruses, and a lower likelihood of inducing drug resistance. In our review article, we have synthesized known host-directed antiviral targets that span diverse cellular pathways and mechanisms, shedding light on the intricate interplay between host cells and viruses. Additionally, we have provided a brief overview of the development of HDAs based on these targets. We aim for this comprehensive analysis to offer valuable perspectives and insights that can guide future antiviral research and drug development efforts.

Objective:
To investigate the epidemiological characteristics of varicella outbreaks in primary and middle schools, and to establish a risk predictive model, so as to provide scientific guidance for the prevention of varicella outbreaks in schools.
Methods:
Based on a nested case-control study, primary and middle schools in 4 districts of Shanghai (Yangpu District and Jingan District) and Hangzhou (Xiaoshan District and Linping District) from January to December 2023 were selected to observe the status of varicella outbreaks. Associated factors of varicella outbreaks were investigated and used for establishing the predictive model, which was evaluated by the Hosmer-Lemeshow(H-L) goodness of fit test, receiver operating characteristic (ROC) curve, Calibration curve, decision curve analysis (DCA).
Results:
A total of 98 varicella outbreaks were included, with 195 schools without varicella outbreaks during the same period as controls. Eight factors, including the availability of warm water in restroom, availability of hand soap in restroom, average class size, duration of student attendance at school per day, presence of a fulltime school doctor, hesitancy of the school principal towards varicella vaccination, and rates of first and second doses of varicella vaccination, were identified as potential factors for school varicella outbreaks, with statistically significant differences (χ2/Z=10.01, 20.49, 17.43, 9.74, 32.17, 6.60, 2.20, 3.39, P<0.05). The 8 variables above were employed to construct a risk predictive model, and Hosmer-Lemeshow goodness of fit test yielded a χ2 value of 5.863 (P>0.05); the area under the ROC curve (AUC) was 0.846 (95%CI=0.799-0.893); Calibration curve analysis indicated good consistency between predicted and actual values of the model. DCA demonstrated favorable predictive performance of the model over a wide range.
Conclusions
The predictive model for school varicella outbreaks demonstrates satisfactory accuracy and efficacy. It suggested to make good use of this prediction model and take relevant measures to reduce the risk of varicella transmission in schools.

OBJECTIVE To investigate the changes in high performance liquid chromatography (HPLC) fingerprint spectra and nucleoside components between Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and its processed product Succus bambusae pinella preparata, providing a reference for the quality evaluation of the latter. METHODS HPLC fingerprint was established for 10 batches of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and its processed product Succus bambusae pinella preparata following the Similarity Evaluation System of TCM Chromatographic Fingerprints (2012 Edition). Hierarchical cluster analysis (HCA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS- DA) were conducted on their common peaks. The contents of four nucleoside components, hypoxanthine, uridine, adenine, and guanosine, in both Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Succus bambusae pinella preparata were determined. RESULTS The similarity between the fingerprints of the 10 batches of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine, Succus bambusae pinella preparata, and their corresponding reference fingerprints ranged from 0.851 to 0.990. A total of 10 common peaks were obtained for both samples, and 4 components were identified as hypoxanthine, uridine, adenine, and guanosine. The results of HCA, PCA and OPLS-DA showed that the samples of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Succus bambusae pinella preparata were clustered into separate categories, with OPLS-DA selecting 4 differential components between them, ranked by variable importance projection values as peak 8, peak 1, peak 6 (adenine) and peak 10. The content determination results showed that the average contents of hypoxanthine, uridine, adenine and guanosine in Succus bambusae pinella preparata declined by 15.90%, 12.00%, 26.04% and 22.18% compared to Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine, respectively, with statistically significant differences in the contents of hypoxanthine, adenine and guanosine (P<0.05 or P<0.01). CONCLUSIONS The established fingerprint and content determination methods are simple to operate and have good repeatability, which are suitable for qualitative and quantitative analysis of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Succus bambusae pinella preparata. The average contents of the four nucleoside components decreased after the processing of Succus bambusae pinella preparata.

Objective:To investigate the current status of vocational training for pediatric clinical research coordinators (CRC), and discuss the construction of base-based pediatric CRC training, and to promote the ability of pediatric CRCs.Methods:From July 25 to October 16, 2023, an anonymous self-designed questionnaire survey was conducted through the Wenjuanxing platform to investigate the current situation of pediatric CRC vocational training and base training needs. The data were collated using Excel. Categorical data were described as numbers and percentages.Results:A total of 328 usable questionnaires were returned. Only 7.62% (25 people) believed that existing CRC training was sufficient and could meet actual work needs; 4.88% (16 people) responded that there was no training; 46.34% (152 people) believed that the training was insufficient to support actual work needs; 87.50% (287 people) believed that continuous CRC training was needed; 46.95% (154 people) preferred experienced CRCs for teaching, who should have at least 3 years of CRC work experience; and 46.95% (154 people) preferred a duration of 3 months for CRC training. The preferred training methods were: practice under the direction of experienced CRCs (90.85%, 298 people), step-by-step teaching of practical skills (88.41%, 290 people), case analysis and discussion (87.20%, 286 people), process simulation (83.23%, 273 people), and lecture-based teaching (76.52%, 251 people). The preferred post-training assessment methods were: case analysis (76.52%, 251 people), operation simulation (74.09%, 243 people), process simulation (73.17%, 240 people), written examination (66.16%, 217 people), and interview (63.72%, 209 people).Conclusions:The current pediatric CRC training is not enough to meet actual work needs. It is urgent to develop and promote a CRC training system that can meet work needs, laying the foundation for the construction of pediatric clinical research ecology in China.
