类Chen-Qi混沌系统的固定时间自适应同步控制

类Chen-Qi四维混沌系统的渐近稳定控制的同步误差不能在有限时间内收敛到零,有限时间控制的同步误差收敛到零的状况与初值有关.因此,本文应用固定时间控制技术,设计了自适应控制器和参数估计律,试图使得驱动系统与同类型的参数未知的响应系统在固定时间内达到同步,完成了理论证明.应用数值仿真考察同步误差收敛到零的状况.选取不同参数值,不同状态初值,考察状态时程图、同步误差曲线等.结果表明:混沌运动时,固定时间内同步误差收敛到零的效果较好,与状态初值无关,收敛时间符合理论计算值;周期运动时,固定时间内前三个状态的同步误差收敛到零的效果较好,收敛时间符合理论计算值,但第四个状态的同步误差的收敛时间不符合理论计算值,其原因是系统存在的三次非线性项的不平衡、不匹配.

Mufangji tang ameliorates pulmonary arterial hypertension through improving vascular remodeling,inhibiting inflammatory response and oxidative stress,and inducing apoptosis

Background:Mufangji tang(MFJT)is composed of Ramulus Cinnamomi,Radix Ginseng,Cocculus orbiculatus(Linn.)DC.,and Gypsum.In clinical settings,MFJT has been effectively employed in addressing a range of respiratory disorders,notably including pulmonary arterial hypertension(PAH).However,the mechanism of action of MFJT on PAH remains unknown.Methods:In this study,a monocrotaline-induced PAH rat model was established and treated with MFJT.The therapeutic effects of MFJT on PAH rat model were evaluated.Network pharmacology was conducted to screen the possible targets for MFJT on PAH,and the molecular docking between the main active components and the core targets was carried out.The key targets identified from network pharmacology were tested.Results:Results showed significant therapeutic effects of MFJT on PAH rat model.Analysis of network pharmacology revealed several potential targets related to apoptosis,inflammation,oxidative stress,and vascular remodeling.Molecular docking showed that the key components were well docked with the core targets.Further experimental validation results that MFJT treatment induced apoptosis(downregulated Bcl-2 levels and upregulated Bax levels in lung tissue),inhibited inflammatory response and oxdative stress(decreased the levels of IL-1β,TNF-α,inducible NOS,and malondialdehyde,and increased the levels of endothelial nitric oxide synthase,nitric oxide,glutathione and superoxide dismutase),reduced the proliferation of pulmonary arterial smooth muscle cells(downregulated ET-1 andβ-catenin levels and ERK1/2 phosphorylation,increased GSK3βlevels).Conclusion:Our study revealed MFJT treatment could alleviate PAH in rats via induction of apoptosis,inhibition of inflammation and oxidative stress,and the prevention of vascular remodeling.

Therapeutic effect of San Bi Tang combined with glucosamine sulfate capsules in cold-dampness-type knee osteoarthritis

BACKGROUND Cold-dampness-type knee osteoarthritis is a common middle-aged and elderly disease,but its pathogenesis is not fully understood,and its clinical treatment has limitations.Glucosamine sulfate capsules are commonly used for treating arthritis,and San Bi Tang is a classic formula of traditional Chinese medicine(TCM)that has the effects of warming yang,dispelling dampness,relaxing muscles,and activating collaterals.This research hypothesized that the combination of modified San Bi Tang and glucosamine sulfate capsules could enhance the clinical efficacy of treating cold-dampness-type knee osteoarthritis through complementary effects.AIM To analyze the clinical efficacy of San Bi Tang combined with glucosamine sulfate capsules when treating cold-dampness-type knee osteoarthritis.METHODS A total of 110 patients with cold-dampness-type knee osteoarthritis were selected as research subjects and randomly divided into a control group and an experimental group of 55 cases each.The control group received only treatment with glucosamine sulfate capsules,while the experimental group received additional treatment with modified San Bi Tang for a duration of 5 wk.The patients’knee joint functions,liver and kidney function indicators,adverse reactions,and vital signs were evaluated and analyzed using SPSS 26.0 software.RESULTS Before treatment,the two groups’genders,ages,and scores were not significantly different,indicating comparability.Both groups’scores improved after treatment,which could indicate pain and knee joint function improvement,but the test group had better scores.The TCM-specific symptoms and the clinical efficacy of the treatment in the test group were higher.Before and after treatment,there were no abnormalities in the patients’liver and kidney function indicators.CONCLUSION The combination of modified San Bi Tang and glucosamine sulfate capsules is superior to treatment with sulfated glucosamine alone and has high safety.

Gaze and Oppositional Gaze in Mr. Tang’s Girls

The gaze is a means of power that can flow through family relationships.It has intense regulatory overtones.In her short story Mr.Tang’s Girls,Malaysian-Chinese Anglophone diasporic writer Shirley Geok-lin Lim shows the conflict between Eastern and Western cultures and the resistance of women under the oppression of patriarchy through the portrayal of the father,Ah Kong,and the eldest daughter,Kim Li.Based on Foucault’s discipline gaze and Hooks’oppositional gaze,this article analyzes the power operation in the story from the following three aspects:the male gaze,discipline and self-discipline,and the oppositional gaze.Kim Li’s subjective image of breaking free from male ownership control has been presented.It suggests the difficulties encountered by female groups in their rebellion against the male gaze and their pursuit of freedom and emancipation.It also reflects the tragedy of awakening women’s destinies under the dual oppression of patriarchy and the East-Westen cultural conflict.

The influence of intestine-based treatment using Xuan Bai Cheng Qi Tang on the concentration of trace elements in the main organs of COPD rats

Objective:To test two theories from traditional Chinese medicine:'exterior -interior relationship between the lung and large intestine' and 'treating from the intestine principle for lung disorders'.The influence of intestine-based treatment using Xuan Bai Cheng Qi Tang (XBCQT) on the concentration of three trace elements-copper (Cu),zinc (Zn),and manganese (Mn)-was observed in the tissues of the lung,small intestine,large intestine,and stomach of rats suffering from chronic obstructive pulmonary disease (COPD).Methods:Thirty-five male Wistar rats were divided randomly and equally into five groups:control;model;Fei treatment (A);Chang treatment (B);and Fei-Chang treatment (C).A rat model of COPD was prepared by tracheal injection of lipopolysaccharide plus exposure to cigarette smoke.Treatments with medicinal herbs started day-22 of administration and exposure to cigarette smoke for 7 days.The control group and model group were administered physiologic (0.9%) saline solution via the stomach.After 7 days of intervention,the tissues of the lung,small intestine,large intestine,and stomach were removed.Inductively coupled plasma-atomic emission spectroscopy was used to detect the levels of Cu,Zn,and Mn in those tissues.Results:Compared with the control group,the Cu concentration in the tissues of the small intestine,large intestine,and stomach increased significantly in the model group (P <.05);the Mn concentration in the tissues of the lung,large intestine,and stomach increased significantly in the model group (P <.05);the Zn concentration in the tissues of the lung and large intestine decreased significantly in the model group (P <.05).In comparison of the model group:the Cu concentration in the tissues of the lung and large intestine decreased significantly in the B group (P <.05);the Mn concentration in the tissues of the lung,small intestine,and large intestine decreased significantly in the B group (P <.05);the Zn concentration in the tissues of the lung,small intestine,and large intestine increased significantly in the B group (P <.05).For the A group versus C group comparison,the Zn concentration in the tissues of the small intestine and stomach increased significantly in the latter (P <.05).Conclusion:This study showed that 'treating from the intestine' using Xuan Bai Cheng Qi Tang and its modified formulae can regulate the concentration of trace elements in the main organs of COPD rats.This may be one of the mechanisms for intestine-based treatment for COPD.

Improved prescription of taohechengqi-tang alleviates D-galactosamine acute liver failure in rats

AIM: To investigate the hepatoprotective effect of improved prescription of Taohechengqi-tang (IPTT) against acute liver failure (ALF) in rats.METHODS: Seventy specific pathogen free male Wistar rats were randomly divided into four groups: control group (normal rats, n = 10), ALF group (ALF model, n = 20), Stronger Neo-Minophagen C (SNMC) group (ALF model + SNMC, n = 20), and IPTT group (ALF model + IPTT, n = 20). The ALF model group was administered an intraperitoneal injection of D-galactosamine (1.4 g/kg), and the control group received normal saline intraperitoneally. The SNMC and IPTT groups were treated with SMMC (15.6 mg/kg) or IPTT (28.6 g/kg) by gavage at 24 h intervals, and the ALF and control groups were treated with normal saline. At 36 h after injection, serum alanine aminotransferase, aspartate aminotransferase, total bilirubin, albumin, and cholinesterase and prothrombin time were determined, and liver histopathological scores were observed by microscopy after hematoxylin and eosin staining. mRNA expression of high mobility group box (HMGB) 1, toll-like receptor (TLR) 4, nuclear factor kappa B (NF-&#x003ba;B) and caspase-3 were analyzed via fluorescence quantitative reverse transcriptase polymerase chain reaction. Proliferating cell nuclear antigen (PCNA) immunohistochemistry in liver tissue was also performed.RESULTS: D-galactosamine notably decreased the biochemical and coagulation profiles in serum. IPTT not only improved liver function and histopathology but also normalized the gene expression levels in liver tissue. Compared with the model group, in the IPTT and SNMC groups, HMGB1 mRNA/&#x003b2;-actin (0.06 &#x000b1; 0.03, 0.11 &#x000b1; 0.04 vs 0.25 &#x000b1; 0.04, P &#x0003c; 0.05); TLR4 mRNA/&#x003b2;-actin (0.07 &#x000b1; 0.02, 0.22 &#x000b1; 0.08 vs 0.41 &#x000b1; 0.22, P &#x0003c; 0.05); NF-&#x003ba;B mRNA/&#x003b2;-actin (0.74 &#x000b1; 0.41, 1.78 &#x000b1; 0.64 vs 2.68 &#x000b1; 1.35, P &#x0003c; 0.05); and caspase-3 mRNA/&#x003b2;-actin levels were all significantly reduced (1.61 &#x000b1; 0.45, 2.57 &#x000b1; 1.04 vs 3.41 &#x000b1; 0.85, P &#x0003c; 0.05). The gene expression levels were significantly lower in the IPTT group than in the SNMC group (P &#x0003c; 0.05). Compared with the model group, the PCNA expression in liver tissue was significantly enhanced in the IPTT and SNMC groups (36.34 &#x000b1; 4.91, 25.57 &#x000b1; 2.94 vs 17.55 &#x000b1; 2.40, P &#x0003c; 0.05).CONCLUSION: IPTT attenuates inflammation in ALF via inhibition of HMGB1 production, which may contribute to limited liver regeneration.
