Background The benefits of early use of norepinephrine in endotoxemic shock remain unknown.We aimed to elucidate the effects of different doses of norepinephrine in early-stage endotoxemic shock using a clinically relevant large animal model.Methods Vasodilatory shock was induced by endotoxin bolus in 30 Bama suckling pigs.Treatment included fluid resuscitation and administration of different doses of norepinephrine,to induce return to baseline mean arterial pressure(MAP).Fluid management,hemodynamic,microcirculation,inflammation,and organ function variables were monitored.All animals were supported for 6 h after endotoxemic shock.Results Infused fluid volume decreased with increasing norepinephrine dose.Return to baseline MAP was achieved more frequently with doses of 0.8µg/kg/min and 1.6µg/kg/min(P<0.01).At the end of the shock resuscitation period,cardiac index was higher in pigs treated with 0.8µg/kg/min norepinephrine(P<0.01),while systemic vascular resistance was higher in those receiving 0.4µg/kg/min(P<0.01).Extravascular lung water level and degree of organ edema were higher in animals administered no or 0.2µg/kg/min norepinephrine(P<0.01),while the percentage of perfused small vessel density(PSVD)was higher in those receiving 0.8µg/kg/min(P<0.05)and serum lactate was higher in the groups administered no and 1.6µg/kg/min norepinephrine(P<0.01).Conclusions The impact of norepinephrine on the macro-and micro-circulation in early-stage endotoxemic shock is dose-dependent,with very low and very high doses resulting in detrimental effects.Only an appropriate norepinephrine dose was associated with improved tissue perfusion and organ function.

The size and shape of the foveal avascular zone(FAZ)have a strong positive correlation with several vision-threatening ret inovascular diseases.The identification,segmentation and analysis of FAZ are of great significance to clinical diagnosis and treatment.We presented an adaptive watershed algorithm to automatically extract F AZ from retinal optical coherence tomography angiography(OCTA)images.For the traditional watershed algorithm,"over-segmentation"is the most common problem.FAZ is often incorrectly divided into multiple regions by redundant"dams".This paper analyzed the relationship between the"dams"length and the maximum inscribed circle radius of FAZ,and proposed an adaptive watershed algorithm to solve the problem of"over-segmentation".Here,132 healthy retinal images and 50 diabetic retinopathy(DR)images were used to verify the accuracy and stability of the algorithm.Three ophthal-mologists were invited to make quan titative and qualitative evaluations on the segmentation results of this algorithm.The quantitative evaluation results show that the correlation coffi-cients between the automatic and manual segmentation results are 0.945(in healthy subjects)and 0.927(in DR patients),respectively.For qualitative evaluation,the percentages of"perfect segmentation"(score of 3)and"good segmentation"(score of 2)are 99.4%(in healthy subjects)and 98.7%(in DR patients),respectively.This work promotes the application of watershed algorithm in FAZ segmentation,making it a useful tool for analyzing and diagnosing eye diseases.

Autophagy is a critical cellular homeostatic mechanism,and its dysfunction is linked to invasive breast carcinoma(BRCA).Recently,several omics methods have been applied to explore autophagic regulators in BRCA;however,more reliable and robust approaches for identifying crucial regulators and druggable targets remain to be discovered.Thus,we report here the results of multi-omics approaches to identify potential autophagic regulators in BRCA,including gene expression(EXP),DNA methylation(MET)and copy number alterations(CNAs)from The Cancer Genome Atlas(TCGA).Newly identified candidate genes,such as SF3 B3,TRAPPC10,SIRT3,MTERFD1,and FBXO5,were confirmed to be involved in the positive or negative regulation of autophagy in BRCA.SF3 B3 was identified firstly as a negative autophagic regulator,and siRNA/shRNA-SF3 B3 were shown to induce autophagyassociated cell death in in vitro and in vivo breast cancer models.Moreover,a novel small-molecule activator of SIRT3,1-methylbenzylamino amiodarone,was discovered to induce autophagy in vitro and in vivo.Together,these results provide multi-omics approaches to identify some key candidate autophagic regulators,such as the negative regulator SF3 B3 and positive regulator SIRT3 in BRCA,and highlight SF3 B3 and SIRT3 as new druggable targets that could be used to fill the gap between autophagy and cancer drug development.

Objective:The accuracy of colposcopy-guided biopsy is key to the success of colposcopic triage in cervical cancer screening programs.However,there is no widely adopted biopsy guideline up to date.Our study aimed to determine whether multi-quadrants biopsy improves the yield of cervical lesions.Methods:Eleven population-based cervical cancer screening studies were conducted in China.Cytology,highrisk human papillomavirus(hrHPV)testing and visual inspection were performed for primary screening.Females positive on one or more tests were referred for colposcopy and biopsy.The proportion of detected cervical intraepithelial neoplasia(CIN)2+and yields by quadrant lesion-targeted biopsy or 4-quadrant random biopsy were compared.Results:Among 4,923 females included,1,606 had quadrant lesion-targeted biopsy,and 3,317 had 4-quadrant random biopsy.The cumulative CIN2+yield increased from 0.10 for only one quadrant-targeted biopsy to 0.21,0.34,and 0.58 for at most two,three and four quadrants targeted biopsies.Among hrHPV positive females with high-grade squamous intraepithelial lesion(HSIL)+cytology,the cumulative CIN2+yield of a second targeted biopsy in another quadrant was significantly increased(P<0.05).Among hrHPV-negative females,the yield of 4-quadrant random biopsies was 0.005,and the yield by lesion-targeted biopsies was 0.017.For hrHPV positive females who had 4-quadrant random biopsy,the additional CIN2+yield for HSIL+,low-grade squamous intraepithelial lesion(LSIL)cytology,or abnormal visual inspection via acetic acid and Lugol’s iodine(VIA/VILI)were 0.46,0.11,0.14.Conclusions:A 4-quadrant random biopsy is recommended only for hrHPV positive females with HSIL cytology,and is acceptable if hrHPV positive with LSIL cytology or with abnormal VIA/VILI.Our findings add evidences for an objective and practical biopsy standard to guide colposcopy in cervical cancer screening programs in low-and middle-income countries.

Objective: To provide a decision-making basis for sustainable and effective development of cervical cancer screening.Methods: This cross-sectional study assesses the service capacity to conduct cervical cancer screening with a sample of 310 medical staff, medical institutions and affiliated township health centers from 20 countylevel/district-level areas in 14 Chinese provinces in 2016.Results: The county-level/district-level institutions were the main prescreening institutions for cervical cancer screening. More medical staff have become engaged in screening, with a significantly higher amounts in urban than in rural areas(P<0.05). The number of human papillomavirus(HPV) testers grew the fastest(by 225% in urban and 125% in rural areas) over the course of the project. HPV testing took less time than cytology to complete the same number of screening tasks in both urban and rural areas. The proportion of mid-level professionals was the highest among the medical staff, 40.0% in urban and 44.7% in rural areas(P=0.406), and most medical staff had a Bachelor’s degree, accounting for 76.3% in urban and 52.0% in rural areas(P<0.001). In urban areas, 75.0% were qualified medical staff, compared with 68.0% in rural areas, among which the lowest proportion was observed for rural cytology inspectors(22.7%). The medical equipment for cervical pathology diagnosis in urban areas was better(P<0.001). HPV testing equipment was relatively adequate(typing test equipment was 70% in urban areas, and non-typing testing equipment was 70% in rural areas).Conclusions: The service capacity of cervical cancer screening is insufficient for the health needs of the Chinese population. HPV testing might be an optimal choice to fill the needs of cervical cancer screening given current Chinese medical health service capacity.

Objective:We aimed to evaluate the effectiveness of different triage strategies for high-risk human papillomavirus(hrHPV)-positive women in primary healthcare settings in China.Methods:This study was undertaken in 11 rural and 9 urban sites.Women aged 35-64 years old were enrolled.HrHPV-positive women were randomly allocated to liquid-based cytology(LBC),visual inspection with acetic acid and Lugol’s iodine(VIA/VILI)(rural only)triage,or directly referred to colposcopy(direct COLP).At 24 months,hrHPV testing,LBC and VIA/VILI were conducted for combined screening.Results:In rural sites,1,949 hrHPV-positive women were analyzed.A total of 852,218 and 480 women were randomly assigned to direct COLP,LBC and VIA/VILI.At baseline,colposcopy referral rates of LBC or VIA/VILI triage could be reduced by 70%-80%.LBC(n=3 and n=7)or VIA/VILI(n=8 and n=26)could significantly decrease the number of colposcopies needed to detect one cervical intraepithelial neoplasia(CIN)2 or worse and CIN3+compared with direct COLP(n=14 and n=23).For the 24-month cumulative detection rate of CIN2+,VIA/VILI triage was 0.50-fold compared with LBC triage and 0.46-fold with the direct COLP.When stratified by age,baseline LBC triage+performed best(P<0.001),peaking among women aged 35-44 years(Ptrend=0.002).In urban sites,1,728 women were hrHPV genotyping test positive.A total of 408,571 and 568women were randomly assigned to direct COLP for HPV16/18+,direct COLP for other hrHPV subtypes+,and LBC triage for other hrHPV subtypes+.LBC(n=12 and n=31)significantly decreased the number of colposcopies needed to detect one CIN2+and CIN3+compared with direct COLP(n=14 and n=44).HPV16/18+increased the 24-month cumulative detection rate of CIN2+(17.89%,P<0.001).Conclusions:LBC triage for hrHPV-positive women in rural settings and direct COLP for HPV16/18+women and LBC triage for other hrHPV subtype+women in urban settings might be feasible strategies.

随着资本市场开放进一步深化,中国经济迈入高质量发展阶段,如何为企业提质增效,是当下我国转型发展难题。本文以2010—2022年A股非金融上市公司为研究对象,通过构建双重差分模型,分析“沪深港通”制度开通这一准自然实验对企业非效率投资的影响。研究结果显示,以“沪深港通”政策为例的资本市场开放主要通过缓解融资约束和减少代理成本这两个渠道抑制企业非效率投资水平,而降低代理成本这一渠道在过度投资的企业中更为明显。进一步研究发现,资本市场开放对信息透明度低、董事会独立性强的企业的影响更显著。研究结果在微观层面提供了资本市场开放所带来正向效果的经验证据,为资本市场制度改革提供有益启示。

Journal of Innovative Optical Health Sciences 2022年第4期15卷 97-107页

作者： Yang Lin Menghan Yu Yi Wang Ziyue Meng Ang Li Zhonghai He Qiaoyun Wang Jian Liu Yao Yu yuqian zhao Xin Zhu Zhenhe Ma School of Control Engineering Northeastern University at Qinhuangdao Qinhuangdao 066004 P.R.China Biomedical Engineering Lab The University of Aizu Aizu-WakamatsuFukushima 965-8580Japan

We propose a high-speed all-optic dual-modal system that integrates spectral domain optical coherence tomography and photoacoustic microscopy(PAM).A 3*3 coupler-based interfer-ometer is used to remotely detect the surface vibration caused by photoacoustic(PA)waves.Three outputs of the interferometer are acquired simultaneously with a multi-channel data ac-quisition card.One channel data with the highest PA signal detection sensitivity is selected for sensitivity compensation.Experiment on the phantom demonstrates that the proposed method can sucessfully compensate for the loss of intensity caused by sensitivity variation.The imaging speed of the PAM is improved compared to our previous system.The total time to image a sample with 256×256 pixels is~20s.Using the proposed system,the microvasculature in the mouse auricle is visualized and the blood flow state is accessed.
