A preliminary study on life history of marine red alga Stylonema alsidii(Zandardini)Drew f.ramosum Zheng et Li

Stylonema alsidii(Zandardini)Drew f.ramosum Zheng et Li is a common species in the genus Stylonema,but there are limited reports on morphological taxonomy and a lack of studies on life history and the regulation of early development.The early development,discoid formation,and erect thallus growth of Stylonema alsidii f.ramosum were observed under laboratory conditions.In addition,the influence of main environmental factors such as temperature and light intensity on its development was briefly studied,and various stages of its life history were observed.The result shows:(1)there are two reproductive modes:asexual reproduction and sexual reproduction;(2)the morphology of this species varies in different degrees under laboratory culture conditions;(3)sexual reproduction and asexual reproduction can coexist under suitable conditions.Five pathways of life history were inferred from experimental phenomena.Mature sporophytes form mature gametophytes by producing initially isolated or initially attached monospore,and mature gametophytes form mature sporophytes by fertilization of eggs and sperms.The sexual and asexual reproduction processes of Stylonema alsidii f.ramosum were reported for the first time,and this is also the first report on sexual reproduction in the genus Stylonema.

The Essential Role of Zheng Qi in Promoting Health: From the Perspective of Chinese Medicine and Modern Medicine

The concept of Zheng Qi in traditional Chinese medicine (TCM) refers to the vital energy produced by the interaction of Yin and Yang forces in the body. Zheng Qi performs two main functions: Wei Qi (defensive Qi), which shields the body from external pathogens, and Ying Qi (nutritive Qi), which sustains the internal organs and enhances their functionality. In TCM, Chinese tonifying herbs can help restore the balance of Yin/Yang and Qi/Blood function in visceral organs (i.e., optimal physiological functions), thereby fostering the efficient production of Zheng Qi and enhancing health. To ensure the quality of Chinese herbal products, functional assays to measure Yin/Yang, Qi/Blood functions, and Zheng Qi production should be implemented. The efficacy of Yang and Qi herbs can be evaluated by their ability to increase mitochondrial ATP in cultured mouse cardiomyocytes, while Yin and Blood herbs are tested through their immunostimulatory effects on antigen-induced T/B cell proliferation in mouse splenocytes and the production of erythropoietin/nitric oxide in hepatocytes/vascular endothelial cells, respectively. Additionally, Zheng Qi’s effect can be gauged by examining natural killer cell activity and antigen-induced T/B cell proliferation in mice ex vivo. These assays act as biomarkers for assessing the quality and effectiveness of herbal health products within TCM theory.

Bakri球囊联合Zheng子宫压迫缝合术治疗产后出血的效果探讨

目的探讨Bakri球囊填塞术联合Zheng子宫压迫缝合术治疗产后出血患者的临床效果。方法将产后出血患者共108例依据手术方案分为2组,其中单纯Zheng子宫压迫缝合术治疗54例为对照组,Bakri球囊联合Zheng子宫压迫缝合术治疗54例为观察组。评价2组患者止血成功率,记录止血时间、术后出血量及住院时间,并观察术后感染及子宫恢复情况。结果观察组止血成功率(98.15%)高于对照组(87.04%),而输血率(1.85%)则显著低于对照组(16.67%),2组比较差异有统计学意义(P<0.05);观察组出血减少率(1.85%),低于对照组(11.11%),但差异无统计学意义(P>0.05);观察组术中出血量、术后24出血量及输血量与对照组比较均明显降低,且出血性恶露时间及住院时间与对照组比较均明显缩短(P<0.05);观察组术后产褥感染、伤口感染及低血容量性休克等并发症发生率分别为9.26%、1.85%、0.05%,与对照组的29.63%、14.81%、7.41%比较差异有统计学意义(P<0.05)。结论在产后出血治疗中采用Bakri球囊联合Zheng子宫压迫缝合术治疗可快速止血,减少术后出血量,保证止血成功,且利于降低术后感染,促进子宫恢复,缩短住院时间,值得推广应用。

Biological Aspects of Orius similis Zheng Reared on Two Preys at Three Constant Temperatures

Mass-rearing of Orius similis Zheng on two preys,Aphis craccivora Koch and eggs of Corcyra cephalonica Stainton at three constant temperatures(22,26 and 30°C)and 60%±10%RH and 16:8 L/D photoperiod under laboratory conditions was investigated to study the effect of different temperatures and different preys on the biology of O.similis.The highest survival rate(%)of nymphal stages was 81.14%and the longest oviposition period for females(20.6 d)was recorded at 26°C.Also,the highest fecundity of female also recorded at 26°C.The highest rate of nymphal feeding consumption was(122.5 individuals of A.cracivora)also,recorded at 26°C.As well as,the two preys had significant effects on the biological characteristics of O.similis.The highest survival rate for nymphal stage was recorded when O.similis nymphs fed on A.cracivora.Therefore,the longest survival rate was founded in the nymphs which fed on the individuals of A.cracivora.During the nymphal period of O.similis which consumed more individuals of A.cracivora than the eggs of C.cephalonica.These results on the effect of three constant temperatures and two preys on the biology of O.similis will share to improve the rearing of O.similis in biological control agents in China and share to suppress the population of pests in field and greenhouse.

The combination of disease and Zheng (syndrome) on the basic of differentiation of six channels:a new pattern of disease diagnosis and treatment of traditional Chinese medicine

Traditional Chinese medicine(TCM)was formed two thousand years ago,and developed in the following centuries.TCM has a unique way of looking at health and illness.Zheng(syndrome)is the basic unit and key term in TCM theory.Zheng is the pathological generalization of a certain stage in the development of disease.Treatment based on syndrome differentiation and disease differentiation of TCM is the basic principle to know and treat diseases,and a kind of special method to study diseases in TCM.In Han Dynasty(200 AD),doctor Zhang Zhongjing proposed Liujing Bianzheng(the differential diagnosis in accordance with the theory of six channels)to diagnose and treat diseases in Treatise on Febrile and Miscellaneous Diseases.In other words,he divided diseases into six channels diseases based on patient's Zhengs.Six channels diseases almost include all of the disease according to his classification standards.In addition,there are development rules in the progress of six channels diseases.Therefore,we hypothesized that combination of six channels disease and Zheng on the basic of differentiation of six channels is a new pattern of diagnosis and treatment diseases in TCM,which is beneficial to the understanding of a certain disease and makes disease treatment more convenient,fast and effective.

Geochemical characteristics of crude oils from Well Zheng-1 in the Junggar Basin, Xinjiang,China

Well Zheng-1 is located in the combined area of the central uplift and the north Tianshan piedmont depression in the Junggar Basin. Two oil-bearing beds are recognized at 4788–4797 m of the Lower Cretaceous Tugulu Formation (K1tg) and 4808.5–4812.5 m of the Lower Jurassic Sangonghe Formation (J1s). The geochemical characteristics of family composition, carbon isotopic composition, saturated hydrocarbons, sterane and terpane biomarkers and carotane of two crude oils are described in this paper. The results show that the geochemical characteristics of the two crude oils are basically similar to each other, indicating they were all derived mainly from the high mature, brine, algae-rich lake facies sediments. Oil-source correlation revealed that crude oils of the two beds were derived mainly from the source rocks of Permian and mixed by the oil derived from the source rocks of Jurassic and Triassic. This is consistent with the geological background with several sets of source rocks in the area studied.
