Clinical Observation on the Improved Short-Term Effects of Anti-Tumor Purified Chinese Medicine Injection Ai-Jing for 138 Cases with Malignant Tumors

The subjects of this study were to observe the improved short-term effects of anti-tumor purified Chinese medicine injection Ai-Jing for 138 cases with malignant tumors. This was a multi-center clinical study, and a total of 138 patients included 96 males and 42 females, with the age from 60 to 76 years. Ai-Jing has obtained the Chinese invention patent since 2008 (ZL991-03528.3). A novel technique acupoint injection method was adopted. Except for lung cancer, patients with other malignant tumors were injected once every other day, 2 ml each time. A course of treatment needs 6 Ai-Jing injections, lung cancer patients need 10 - 20 Ai-Jing injections. At the same time, patients were treated with traditional medicine decoction. Due to the limited number of cases, cure rate, recovery rate and remission rate were calculated as a whole, respectively 18.12%, 44.20% and 32.15%. All the invalid patients were lung cancer, accounting for 16.67% of the patients treated with lung cancer, and the total treatment inefficiency was 6.52%. Conclusion: Chinese Medicine Injection Ai-Jing extracts the effective components of anti-cancer and tumorigenesis, and has the effects of anti-cancer and tumorigenesis, anti-inflam-matory and analgesic, and repairing body damage, with small toxic and side effects and low cost.

Identification of annual routines and critical stopover sites of a breeding shorebird in the Yellow Sea,China

Pied Avocets(Recurvirostra avosetta)are common migratory shorebirds in the East Asian–Australasian Flyway.From 2019 to 2021,GPS/GSM transmitters were used to track 40 Pied Avocets nesting in northern Bohai Bay to identify annual routines and key stopover sites.On average,southward migration of Pied Avocets started on 23 October and arrived at wintering sites(mainly in the middle and lower reaches of the Yangtze River and coastal wetlands)in southern China on 22 November;northward migration started on 22 March with arrival at breeding sites on 7 April.Most avocets used the same breeding sites and wintering sites between years,with an average migration distance of 1124 km.There was no significant difference between sexes on the migration timing or distance in both northward and southward migration,except for the departure time from the wintering sites and winter distribution.The coastal wetland of Lianyungang in Jiangsu Province is a critical stopover site.Most individuals rely on Lianyungang during both northward and southward migration,indicating that species with short migration distances also heavily rely on a few stopover sites.However,Lianyungang lacks adequate protection and is facing many threats,including tidal flat loss.We strongly recommend that the coastal wetland of Lianyungang be designated as a protected area to effectively conserve the critical stopover site.

A Literature Review of Wave-Induced Heave Motion of Floating Structures

This paper provides comprehensive review on heave motion of rigid floating structure due to wave impacts.To specify and explain the structure response,this review firstly provides a brief introduction on ocean sea wave theory,floating structure motion interpretation.Then the floating body motion in regular waves was demonstrated using a superposition method of the oscillated motion in still water and the restrained motion in waves.Meanwhile,added mass and damping coefficient,these two frequency-dependent terms are brought into discussion to generate the motion response with given wave amplitude,which is known for response amplitude operator(RAO).Based on the study in regular waves,RAO of floating structure in irregular waves is introduced while no longer in time domain but in frequency domain.The whole review covers the literatures from the early 1980s up to nowadays,based on the review,it is recommended that more experimental work regarding to frequency characteristic and relative response of larger floating body should be carried out to improve the accuracy of this method.

一种基于公众科学数据的区域性鸟类多样性评价方法

鸟类是理想的生物多样性指示类群。中国观鸟记录中心(以下简称“记录中心”)是目前中国最大的鸟类监测公众科学数据平台,其记录覆盖94%的全国鸟种和94.3%的县级行政区。本研究基于公众科学数据,参考《区域生物多样性评价标准》(HJ623-2011)中的受胁物种丰富度指数,构建了鸟类丰富度指数(RB_A)和珍稀濒危鸟类丰富度指数(RTB_A),继而提出一种对区域鸟类多样性进行评价的新方法。本研究计算了自2014年起,各省级、地级、县级行政区(不含市辖区)每年在记录中心的累积记录鸟种数对官方发布鸟种数的覆盖率和省级行政区记录的累积珍稀濒危鸟种数对官方发布数据的覆盖率,并计算了自2018年起各级行政区每年的RB_A和RTB_A,以了解各地鸟类丰富度指数的逐年变化情况,并分析记录中心数据集的发展趋势和两个指数的敏感性。分析结果表明,记录中心数据对全国各级行政区的鸟种覆盖率自2014年起逐年增加,在2023年分别有94.1%的省级、59.0%的地级和49.0%的县级行政区(不含市辖区)的鸟种覆盖率超过90%;记录中心的累积珍稀濒危鸟种数据在省级行政区的覆盖率亦呈上升趋势,但略低于所有鸟种覆盖率。自2020年起,全国每年观测到的鸟种数量呈逐年增加趋势,但其中部分省份每年观测到的鸟种总数在2022年出现下降。自2020年起,各省级行政区的RB_A和RTB_A整体呈现上升趋势。RB_A范围为0.50–0.96,RTB_A范围为0.45–0.98,显示RTB_A更为敏感。本研究结果表明,RB_A和RTB_A在本地用户提交记录数量充足的地区有较大的应用价值,可作为生物多样性评价指标应用。RTB_A对于鸟类多样性的变化更为敏感,更能体现在地鸟类保护状况。随着记录中心等公众科学平台的发展,以RB_A和RTB_A为代表的基于公众科学的评价指数在物种多样性评估和物种监测方面有巨大的应用潜力。

1D-2D nanohybrid-based textile strain sensor to boost multiscale deformative motion sensing performance

The development of strain sensors with both superior sensitivity(gauge factor(GF)>100)and broad strain-sensing range(>50%strain)is still a grand challenge.Materials,which demonstrate significant structural deformation under microscale motion,are required to offer high sensitivity.Structural connection of materials upon large-scale motion is demanded to widen strainsensing range.However,it is hard to achieve both features simultaneously.Herein,we design a crepe roll structure-inspired textile yarn-based strain sensor with one-dimensional(1D)-two-dimensional(2D)nanohybrid strain-sensing sheath,which possesses superior stretchability.This ultrastretchable strain sensor exhibits a wide and stable strain-sensing range from microscale to large-scale(0.01%–125%),and superior sensitivity(GF of 139.6 and 198.8 at 0.01%and 125%,respectively)simultaneously.The strain sensor is structurally constructed by a superelastic 1D-structured core elastomer polyurethane yarn(PUY),a novel high conductive crepe roll-structured(CRS)1D-2D nanohybrid multilayer sheath which assembled by 1D nanomaterials silver nanowires(AgNWs)working as bridges to connect adjacent layers and 2D nanomaterials graphene nanoplates(GNPs)offering brittle lamellar structure,and a thin polydopamine(PDA)wrapping layer providing protection in exterior environment.During the stretching/deformation process,microcracks originate and propagate in the GNPs lamellar structure enable resistance to change significantly,while AgNWs bridge adjacent GNPs to accommodate applied stress partially and boost strain.The 1D crepe roll structure-inspired strain sensor demonstrates multifunctionality in multiscale deformative motion detection,such as respiratory motions of Sprague–Dawleyw rat,flexible digital display,and proprioception of multi-joint finger bending and antagonistic flexion/extension motions of its flexible continuum body.
