With the development of the design complexity in embedded systems, hardware/software （HW/SW） partitioning becomes a challenging optimization problem in HW/SW co-design. A novel HW/SW partitioning method based on position disturbed particle swarm optimization with invasive weed optimization （PDPSO-IWO） is presented in this paper. It is found by biologists that the ground squirrels produce alarm calls which warn their peers to move away when there is potential predatory threat. Here, we present PDPSO algorithm, in each iteration of which the squirrel behavior of escaping from the global worst particle can be simulated to increase population diversity and avoid local optimum. We also present new initialization and reproduction strategies to improve IWO algorithm for searching a better position, with which the global best position can be updated. Then the search accuracy and the solution quality can be enhanced. PDPSO and improved IWO are synthesized into one single PDPSO-IWO algorithm, which can keep both searching diversification and searching intensification. Furthermore, a hybrid NodeRank （HNodeRank） algorithm is proposed to initialize the population of PDPSO-IWO, and the solution quality can be enhanced further. Since the HW/SW communication cost computing is the most time-consuming process for HW/SW partitioning algorithm, we adopt the GPU parallel technique to accelerate the computing. In this way, the runtime of PDPSO-IWO for large-scale HW/SW partitioning problem can be reduced efficiently. Finally, multiple experiments on benchmarks from state-of-the-art publications and large-scale HW/SW partitioning demonstrate that the proposed algorithm can achieve higher performance than other algorithms.

Dear Editor,Ocular decompression retinopathy(ODR),which manifests as diffuse retinal hemorrhage occurring abruptly in multiple locations,including the subretinal,intraretinal,and preretinal spaces,is a rare complication after glaucoma surgery and is caused by sudden,iatrogenic lowering of intraocular pressure(IOP).Implicated procedures include glaucoma drainage implantation,trabeculectomy,iridotomy,and even cataract surgery[1].One report described a case of ocular decompression management following uncomplicated cataract surgery with no posterior capsular rupture or other intraoperative complications[2].Here,we report a rare case of ODR triggered by phacoemulsification and the use of systemic chemotherapeutic drugs in a patient with primary acute angleclosure glaucoma(PACG).The case not only improves our understanding of potential side effects of chemotherapeutic drugs on ophthalmic surgery but may also serve as a reference for clinicians in the management of patients with glaucoma with similar medical histories.

The extraction yields, active compounds and antioxidant properties of 50%-aqueous-ethanolic extracts of freeze-dried Echinacea purpurea flower with multi-steps and multi-batches extraction methods were assessed. In multi-steps extraction, the extraction yields of 1st, 2nd, and 3rd extracts were 21.52%, 9.33%, and 2.90%, and their total phenols contents were 182.08, 176.33, and 177.08 mg CAE/g, respectively, with cichoric acid (62.07 - 66.57 mg/g) being the main phenolic compound. No differences in the contents of individual and total caffeic acids derivates existed among 1st, 2nd, and 3rd extracts. The dodeca-2E, 4E, 8Z, 10(E/Z)-tetraenoic acid isobutylamide (alkamide 8/9) contents of 1st, 2nd, and 3rd extracts were 505.38, 598.61, and 585.99 µg/g, respectively. In multi-batches extraction, the extracted dry weight increased with increasing the sample batches, with the extraction yields and alkamide 8/9 contents of samples decreased from 19.93% to 12.98% and 534.36 to 269.76 µg/g, respectively. The total phenol (177.25 - 186.92 mg CAE/g), individual and total caffeic acid derivatives (85.99 - 95.06 mg/g) contents of extracts among different sample batches were not significantly different, with cichoric acid (63.66 - 70.31 mg/g) being the main phenolic compound. All the prepared extracts also exhibited potent antioxidant properties. Overall, the two-step sequential extraction is desirable for extracting bioactive compounds from freeze-dried E. purpurea flower.

Background： The effect of ovarian hyperstimulation syndrome （OH SS） on pregnancy outcomes of in vitro fertilization （IVF） patients is still ambiguous. Tbis study aimed to analyze pregnancy outcomes of IVF with or without OHSS in Chinese patients. Methods： A retrospective cohort study was undertaken to compare pregnancy outcomes between 190 women with OHSS and 197 women without OHSS. We examined the rates of clinical pregnancy, multiple pregnancies, miscarriage, live birth, preterm deliver）,, preterm birth before 34 weeks＇ gestation, cesarean delivery, low birth weight （LBW）, and small-for-gestational age （SGA） between the two groups. Odds ratios （ORs） and 95% confidence intervals （Cls） of measure of clinical pregnancy were also analyzed. Results： The clinical pregnancy rate of OHSS patients was significantly higher than that of non-OHSS patients （91.8% vs. 43.5%, P 〈 0.001）. After controlling for drug protocol and causes of infertility, the adjusted ORs of moderate OHSS and severe/critical OHSS for clinical pregnancy were 4.65 （95% CI, 1.86-11.61 ） and 5.83 （95% CI, 3.45-9.86）, respectively. There were no significant differences in rates of muhiple pregnancy （4.0% vs. 3.7%） and miscarriage （16.1% vs. 17.5%） between the two groups. With regard to ongoing clinical pregnancy, we also found no significant differences in the rates of live birth （82.1% vs. 78.8%）, preterm delivery （20.9% vs. 17.5%）, preterm birth before 34 weeks＇ gestation （8.6% vs. 7.9%）, cesarean delivery （84.9% vs. 66.3%）, LBW （30.2% vs. 23.5%）, and SGA （21.9% vs. 17.6%） between the two groups. Conclusion： OHSS, which occurs in the luteal phase or early pregnancy in IVF patients and represents abnormal transient hemodynamics, does not exert any obviously adverse effect on the subsequent pregnancy.

Pt与Au的原子序数相近,X射线激发下,影响它们荧光强度的诸多因素都非常相近,据此建立了利用金首饰系列标准物质（只含Au、Cu元素）和Pt、Cu峰面积修正,X射线荧光光谱法（XRF）测定铂首饰样品（只含Pt、Cu元素）中Pt含量的分析方法。首先,通过测定金首饰系列标准物质,绘制Cu含量(w;)与Cu、Au峰面积比值Q(I;/I;)之间的校准曲线;其次,通过试验对铂首饰标准物质的Pt和Cu的峰面积进行修正,并计算其Q值;最后,采集铂首饰样品的谱图,求Q值,查校准曲线,即可求出铂首饰中的Cu含量,进而间接计算出Pt的含量。方法适用于铂质量分数为91.70%;9.92%的铂首饰的测定。对5件铂首饰样品进行测定,结果与原子吸收光谱法（AAS）一致。实验方法解决了测定铂首饰中的铂时缺乏铂标准样品的难题。

AIM： To investigate the effect of replication-incompetent adenovirus vector expressing MDA-7/IL-24 on tumor growth and apoptosis in human hepatocellular carcinoma （HCC） cell line HepG2 and normal liver cell line L02. METHODS： We constructed the recombinant replication-incornpetent ***-7 virus vector and infected it into the human HCC cell line HepG2 and normal liver cell line L02. RT-PCR was performed to detect the rnRNA expressing in cells, by ELISA was used to detect MDA-7/IL-24 protein expression in the culture supernatant. The effect of apoptosis induced by ***-7 was confirmed by Hoechst staining and flow cytometry assay with Annexin-V and PI staining. MTT assay was used to determine growth inhibition of HepG2 cells, and cell-cycle and hypodiploidy analyses were performed by flow cytometry. RESULTS： Recombinant replication-defective virus expressing MDA-7/IL-24 was constructed successfully. RTPCR showed that the ***-7 could mediate the expression of the exogenous gene MDA-7/IL-24 into HepG2 and L02. The concentration of MDA-7/IL-24 protein in supernatant was 130 pg/mL and 110 pg/mL in ***-7-infected L02 and HepG2 ceils, respectively. ***-7 infection obviously induced apoptosis （from 2.604±0.72% to 33.64±13.2%, P=0.00012） and growth suppression in HepG2 （inhibition ratio IR=68%） and an increase in the percentage of specific cancer cell types at the G2/M phase of the cell cycle （from 6.44% to 32.29%, P〈 0.01）, but not in L02 ***： These results confirm selectively induction of apoptosis and growth suppression by the mda-7/ IL-24 gene with replication-incompetent adenovirus vector in human hepatocellular carcinoma cell line HepG2.

人民监督员制度本是检察机关办理职务犯罪案件的监督机制。国家监察体制改革后职务犯罪调查权转移至监察委员会,人民监督员制度受到冲击,亟待转型重塑。在法理层面,基于司法民主的要求,人民监督员制度应定位为检察工作的外部监督机制,而非职务犯罪调查的外部监督机制;在观念层面,要理顺监察体制改革与司法体制改革的关系,通过深化司法改革解决监察体制改革后的遗留问题;在操作层面,要因应"捕诉合一"制度改革,将人民监督员的监督重点放在检察机关的批捕与起诉行为上。在人民监督员制度内部改革方面,要确保监督评议过程的独立性,增强监督评议结果的约束力,并注重保障人民监督员的知情权、监督权以及人身权,从而实现人民监督员制度的功能回归。
