Single‐crystal, metastable, hexagonal In2O3 (H‐In2O3) nanofibers with an average diameter of 80 nm and length of up to several micrometers were synthesized on a large scale, for the first time under ambient pressure, by annealing InOOH nanofibers at 490 °C. The InOOH nanofibers were prepared by a controlled hydrolysis solvothermal reaction, using InCl3·4H2O as the starting material and ether as the solvent, in the temperature range of 190–240 °C. The solvent has significant effects on the formation of the metastable phase and the morphology of the In2O3 nanocrystals during the synthesis of the precursor InOOH. Room‐temperature optical absorption spectra of the hexagonal In2O3 nanofibers showed strong absorption peak located at 325 nm (3.83 eV) with a slight blue‐shift compared with that of bulk In2O3 (3.75 eV). The H‐In2O3 nanofibers photoluminesce at room temperature with emission peaks at 378 nm, 398 nm, and 420 nm. The successful production of metastable hexagonal In2O3 nanofibers in large scale under mild conditions could be of interest both for applications and fundamental studies.

By taking advantage of their intense visible-light absorptions, a photoinduced, Ag I promoted oxidative dimerization of BODIPY dyes was developed to give structurally unprecedented α,αand α,γ-linked dimers. In contrast to classical oxidative aromatic coupling, this methodology does not need a strong oxidant and relies on the singlet electron transfer process between excited-state BODIPYs and an electron acceptor to generate BODIPY based radical species.

Objective: To explore the effect of cognitive behavioral therapy (CBT) in combination with systemic family therapy (SFT) on mild to moderate postpartum depression and sleep quality. Methods: 249 primiparous women with mild to moderate postpartum depression were recruited and randomly assigned to a control group (n=128), which received conventional postpartum care, or to a psychological intervention group (n=121), which received conventional postpartum care combined with psychological intervention. The Edinburgh Postnatal Depression Scale (EPDS) and Pittsburgh Sleep Quality Index (PSQI) were employed to evaluate depression and sleep quality, respectively. Results: 104 patients in the intervention group and 109 in the control group completed the study. After intervention, the EPDS score, PSQI score, sleep quality score, sleep latency score, sleep duration score, habitual sleep efficiency score, sleep disturbance score, and daytime dysfunction score were significantly lower in the intervention group than in the control group. The EPDS and PSQI scores of each group at different time points after intervention were markedly decreased compared with those before intervention, and the reduction in the intervention group was more evident than that in the control group. Conclusion: CBT in combination with SFT can improve depression and sleep quality in patients with mild to moderate postpartum depression.

A metal- and additive-free photochemical strategy for the direct arylation of boron dipyrromethene dyes (BODIPYs) at their 3,5-positions is reported. The operationally simple approach occurs under illumination by visible light in the absence of any external photoredox catalyst. The chemistry is driven by the singlet excited state (1PS*) of BODIPYs upon visible-light absorption while successively triggering the formation of aryl radicals from aryl diazonium salts. Furthermore, a new type of indole-fused BODIPY with NIR absorption has also been synthesized for the first time.

Purpose To evaluate the early changes in retinal microcirculation after uncomplicated cataract surgery using an active-fluidics system. Materials and methods Patients underwent uncomplicated cataract surgery for both eyes were enrolled. The two eyes of the patients were randomly assigned to two groups, the active-fluidics group and the gravity-fluidics group. One eye using an activefluidics system, and the other using a gravity-fluidics system. Optical coherence tomography angiography (OCTA) was performed at 1 day, 7 days, 30 days, and 90 days after surgery. Results Fifty eyes (25 patients) were included in the final analysis. A significantly lower cumulative dissipated energy (CDE), estimated fluid usage (EFU), and total aspiration time (TAT) were observed in the active-fluidics group (all P\0.05). The superficial vessel density at parafoveal region increased at 7 days and 30 days after cataract surgery in the eyes of both the active-fluidics and gravity-fluidics groups, with the fluctuation in eyes of the gravity-fluidics group more significant. The vessel density of deep capillary plexus remained stable during the follow-up period. Significant changes of retinal thickness in macular region (fovea, parafovea) were observed in eyes of the gravity-fluidics group through the comparison of corresponding values at different time points (p = 0.008, 0.005). No significant change in retinal thickness was observed in eyes of the active-fluidics. Conclusions Retinal microcirculation and thickness were disturbed after cataract surgery using the gravityfluidics infusion system. The active-fluidics system not only improved the surgical efficacy but also protected the retinal vasculature during cataract surgery.Clinical trials registration: The study has been registered at www.clinicaltrials.gov with its clinical trial accession number of NCT0130500.
