Temperate-zone insects typically survive winter by entering diapause. Although many aspects of insect diapause have been studied, the underlying molecular mechanism of insect diapause is not well understood. Here we report the results of the transcriptional and translational differences of migratory locust eggs at different embryonic states using diapause （low temperature） and non-diapause （high temperature） regimes. Compared with non-diapause eggs at 100 degree-days （N2） treatment, 29671 transcripts and 296 proteins were differentially expressed at the diapause maintenance stage （D2）. While compared with 150 degree-days （N3） treatment, 45 922 transcripts and 404 proteins were differentially expressed in the post-diapause stage （D3）. Among them, 51 and 102 transcripts had concurrent transcription and translation profiles in D2 vs. N2 and D3 vs. N3 treatments, respectively. Analysis of Gene Ontology categorized these genes and proteins into three categories： biological processes, cellular components, and molecular functions. Biological pathway analysis indicat- ed that three pathways：（1） insect hormone biosynthesis （KEGG： Map 00981）, （2） the insulin signaling pathway （KEGG： Map 04910）, and （3） the peroxisome proliferator-activated receptor （PPAR） signaling pathway （KEGG： Map 03320） play an important role in locust diapause regulation. Most of these transcripts and proteins were up-regulated in the diapause treatments, and were highly linked to juvenile hormone biosynthesis, insulin and PPAR signaling pathways, suggesting these three pathways may be Jnvolved Jn diapause and development regulation. This study demonstrates the applicability of high-throughput omics tools to identify biochemical pathways linked to diapause in locust egg development. In addition, it reveals that cellular metabolism in diapause eggs is more inactive than in non-diapause eggs, and most of the down-reg- ulated enzymes and pathways are related to reduce energy loss.

AIM: To investigate the efficacy and safety of the treatment of endoscopic trans-ethmosphenoid optic canal decompression(ETOCD) with combination of steroid in patients with newly onset indirect traumatic optic neuropathy(ITON) and compare the outcome between immediate ETOCD treatment and ETOCD with preoperative steroid treatment. METHODS: Patients presented as newly onset ITON(suffered trauma within 3 d) at a tertiary medical center between Mar 1 st, 2016 and Mar 1 st, 2018 were enrolled in this study. All patients were equally and randomly divided into 2 groups. Cases in group A were performed ETOCD immediately after admition while cases in group B were prescribed by methylprednisolone(20 mg/kg · d) for 3 d before ETOCD. Methylprednisolone(20 mg/kg · d) was used after surgery for 6 d in group A and 3 d in group B. Follow-up was up to 3 mo in all cases. Visual acuity(VA) before and after treatment between the two groups were taken into comparison. RESULTS: Complete postoperative data were acquired from 34 patients in group A and from 32 patients in group B. Group A had significantly higher effective rate in VA than group B(χ~2 =4.905, P=0.027).CONCLUSION: For patients with newly onset ITON, combination treatment of ETOCD with high-dose steroid is an effective and safe way. Immediate surgery will lead to better prognosis for these cases.

A software-based method is proposed to eliminate the flooding interference strips in B-mode images, and to evaluate the cavitation bubbles generated during high intensity focused ultrasound （HIFU） exposures. In vitro tissue phantoms are exposed to 1.12 MHz HIFU pulses with a fixed 100 Hz pulse repetition frequency. HIFU-induced cavitation bubbles are detected as hyperechoic regions in B-mode images. The temporal evolution of cavitation bubbles, generated by HIFU pulses with varying driving amplitude and pulse length, is analyzed by measuring the time-varying area of the hyperechoic region. The results show that： first, it is feasible to monitor HIFU-induced cavitation bubble activity in real-time using B-mode imaging; second, more cavitation bubbles can be generated with higher acoustic energy delivered; third, the hyperechoic region is observed to shrink gradually after ceasing the HIFU pulses, which indicates the dissolution of cavitation bubbles. This work will be helpful for developing an effective tool to realize real-time monitoring and quantitative evaluation of HIFU-induced cavitation bubble activity using a current commercialized B-mode machine.
