The effect of vitamin D supplementation on individuals with autism spectrum disorder (ASD) is inconclusive. We aimed to conduct a meta-analysis of the available randomized controlled trials (RCTs) to explore whether vitamin D supplementation can improve core symptoms and coexisting conditions in children with ASD. Data were obtained by searching the PubMed, Embase, Web of Science, CINAHL and Cochrane Library databases up to February 2022 following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Using a random-effects model, mean differences with 95% confidence intervals (CIs) were calculated through a meta-analysis. There were eight RCTs with 266 children with ASD in the present review, among which six RCTs were included in the meta-analysis. Children who received vitamin D supplementation showed a significant improvement in stereotypical behavior scores (pooled mean difference (MD): −1.39; 95% CI: −2.7, −0.07; p = 0.04) with low heterogeneity (I2 = 34%), and there was a trend toward decreased total scores on the Social Responsiveness Scale (SRS) and Childhood Autism Rating Scale (CARS, p = 0.05); however, there were no other significant differences in the core symptoms of ASD and coexisting conditions between groups as measured by the Aberrant Behavior Checklist (ABC). Vitamin D supplementation appears to improve stereotypical behaviors but does not improve other core symptoms and coexisting conditions. Further randomized controlled trials with large sample sizes and individualized doses are needed.

The objective of this research was to study the in situ and in vivo nasal absorption of Geniposide (Ge) co-administered with borneol. A rat in situ nasal perfusion technique with a novel volumeadjusted calculation was used to examine the absorption rate and extent of Ge. The influence of different experimental conditions such as purity of extract, drug concentration, co-administration with synthetic borneol or natural borneol were also investigated. Results indicated nasal absorption of Ge was primarily by passive diffusion that resembled first order kinetics. Following co-administration with borenol, the drug absorption was increased by 1.4 and 1.7 folds for natural borneol and synthetic borneol , respectively. However, the effect of other factors on drug absorption was not significant. In addition, it was also observed that there is a positive correlation between the absorption of water and Ge by the nasal route. In vivo studies carried out in rats where Ge was co-administered with NB and the pharmacokinetic profile obtained following intranasal administration were compared with those after intravenous administration. The bioavailability of Ge by intranasal was 101.5% and Tmax was 2.04 ± 0.64 min. MRT was 218.7 ± 74.1 min and 44.4 ± 8.9 min for intranasal and intravenous, respectively. Combined with the borneol,Ge can be promptly and thoroughly absorbed intranasally in rats.

Bioassay-guided fractionation of extracts from Fructus Gardeniae led to analysis of its bioactive natural products. After infection by influenza virus strain A/FM/1/47-MA in vivo,antiviral activity of the extracts were investigated. The target fraction was orally administered to rats and blood was collected. High-performance liquid chromatography coupled with photo diode array detector and electrospray ion trap multiple-stage tandem mass spectrometry was applied to screen the compounds absorbed into the blood. A structural characterization based on the retention time, ultraviolet spectra, parent ions and fragmentation ions was performed. Thirteen compounds were confirmed or tentatively identified. This provides an accurate profile of the composition of bioactive compounds responsible for the anti-influenza properties.

<P><B>Abstract</B></P> <P>To produce hydrogen and oxygen from photocatalytic overall splitting of pure water provides a promising green route to directly convert solar energy to clean fuel. However, the design and fabrication of high-efficiency photocatalyst is challenging. Here we present that by connecting different nanostructures together in a rational fashion, components that cannot individually split water into H<SUB>2</SUB> and O<SUB>2</SUB> can work together as efficient photocatalyst with high solar-to-hydrogen (STH) energy conversion efficiency and avoid the use of any sacrificial reagent. Specifically, Te/SnS<SUB>2</SUB>/Ag artificial nanoleaves (ANLs) consist of ultrathin SnS<SUB>2</SUB> nanoplates grown on Te nanowires and decorated with numerous Ag nanoparticles. The appropriate band structure of Te/SnS<SUB>2</SUB> p-n junctions and the surface plasmon resonance of Ag nanoparticles synergistically enhance the quantum yield and separation efficiency of electron-hole pairs. As a result, Te/SnS<SUB>2</SUB>/Ag ANLs enable visible-light driven overall water-splitting without any sacrificial reagent and exhibit high H<SUB>2</SUB> and O<SUB>2</SUB> production rates of 332.4 and 166.2μmolh<SUP>−1</SUP>, respectively. Well-preserved structure after long-term measurement indicates its high stability. It represents a feasible approach for direct H<SUB>2</SUB> production from only sunlight, pure water, and rationally-designed ANL photocatalysts.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Te/SnS<SUB>2</SUB>/Ag ANLs heterostructure is prepared to catalyze overall water splitting. </LI> <LI> The catalyst show impressive H<SUB>2</SUB> and O<SUB>2</SUB> production rate under visible light. </LI> <LI> The structure and efficiency of catalyst shows no degradation after 10 days. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

The use of uricase-deficient mammals to screen formulations of engineered uricases as potential drugs for hyperuricemia involves heavy costs and presents a technical bottleneck. Herein, a new practical system was investigated to evaluate the pharmacological significance of a bacterial uricase based on its ability to eliminate uric acid in plasma in vitro, its pharmacokinetics in vivo in healthy rats, and the modeled pharmacodynamics in vivo. This uricase, before and after modification with the monomethyl ether of poly(ethylene glycol)-5000, effectively eliminated uric acid in vitro in rabbit plasma, but its action was susceptible to xanthine inhibition. After intravenous injection of the modified uricase without purification, a bi-exponential model fit well to uricase activities in vivo in the plasma of healthy rats; the half-life of the modified uricase was estimated without interference from the unmodified uricase leftover in the sample and was nearly 100-fold longer than that of the unmodified uricase. Using a model of the elimination of uric acid in vivo taking into account of uricase pharmacokinetics and xanthine inhibition, modeled pharmacodynamics supported that the half-life of uricase and its susceptibility to xanthine are crucial for the pharmacological significance of uricase. Hence,this practical system is desirable for doing preliminary screening of formulations of engineered uricases as potential drugs for hyperuricemia.

Background Ovarian cancer is the one of the most deadly gynecologic malignancy among cancer related death in women. However, the treatment for ovarian cancer is still limited. In this study, we aimed to explore the inhibition potential of miR- 377-3p in ovarian cancer and explore the mechanism of this effect. Methods Quantitative real-time PCR was used to detect the mRNA or microRNA (miRNA) levels. CCK-8, wound-healing, transwell assay were used to detect cell proliferation, migration and invasion. The protein levels were examined by western blot. The dual luciferase reporter assay was conducted to examine the luciferase activity. Tumor volume was measured and Ki67 was detected via immunohistochemistry. Results qRT-PCR results showed that miR-377-3p was downregulated in ovarian cancer patients. MiR-377-3p mimics suppressed cell proliferation, migration, invasion and decreased the JAG1 level. However, miR-377-3p inhibitor promoted these appearances. Interestingly, we found JAG1 was a target gene of miR-377-3p. JAG1 overexpression reversed the miR- 377-3p-induced inhibition of proliferation and invasion. In addition, miR-377-3p inhibited ovarian cancer tumorigenesis in vivo, indicating by decreased tumor volume and staining of Ki67. Conclusion The results showed that miR-377-3p inhibited growth and invasion of ovarian cancer cells by targeting JAG1.
