The Influencing Mechanism and Motivation of the Bystander on the Choice of Chinese Address Forms.

Chinese address terms exhibits a high degree of variability. Guided by the extended context of situation framework within the field of systemic functional linguistics, and taking the dialogues of the modern Chinese TV drama In the Name of People as examples, this study investigated how the bystander influences the choice of address terms. It is found that the appearance of the bystander influences the choice of address terms. Yet, it is not a direct process but is mediated by conversational atmosphere. Specifically, the presence of a bystander triggers "situational synergy" or changes interpersonal relationship, and then change the conversational atmosphere, both paths ultimately impact the choice of address terms. The underlying forces that lead to the variability of Chinese address terms are guan ben wèi and miàn zǐ. This study suggests the intricate impact of context on language choice, as well as the interdependency of context variables. In addition, by taking the concept of face beyond its European/North American milieu, and relocating it following the Chinese point of view, group orientation is valued, which contributes to face study.

[Theory and application of pulse diagnosis at Renying and Cunkou regions].

Renying and Cunkou pulse diagnostic method is one of the important parts of the pulse diagnosis in Huangdi Neijing (Inner Canon of Yellow Emperor) and has been controversial since its proposal. This article takes WANG Shu-he's diagnostic operation as the evidence, and is in reference of the statement, "Cun region (the region ahead of Guan region of Cunkou) determines the human life, that on the left hand refers to Renying, while on the right hand is Qikou". The pulse conditions on the left and right hands represent yin and yang. If Renying pulse on the left is greater, the diseases are in yang meridians, while if Cunkou pulse on the right is bustling, the diseases are in yin meridians. By comparing the pulse condition and strength, as well as the pulse beating (rapid and urgent) between Guan region and region ahead of Guan on the same side, the conditions of three yang and three yin meridians are detected. In treatment, based on the records of Renying and Cunkou pulse diagnosis in Huangdi Neijing, the principles are proposed for reinforcing and reducing methods on hand and foot meridians of yin and yang. Five-shu points and yuan-source points are taken as the main acupoints in acupuncture treatment. During treatment, the changes in pulse conditions should be emphasized specifically and those at Renying and Cunkou regions are the criteria for judging qi arrival and qi regulation.

Metabolomics analysis of the potential mechanism of Yi-Guan-Jian decoction to reverse bone loss in glucocorticoid-induced osteoporosis.

BACKGROUND: Glucocorticoid-induced osteoporosis (GIOP) is a disease in which long-term use of glucocorticoid causes bone loss, deterioration of bone microstructure and fracture. Currently, clinical drugs targeting this disease have certain side effects. There is still a need to find effective drugs with fewer side effects. The theory of traditional Chinese medicine suggests that YGJ has therapeutic effect on GIOP, but it has not been explained. Therefore, this study aims to explore the protective effect of YGJ on GIOP mouse models and elucidate the underlying mechanism through LC-MS-based metabolomics analysis. METHODS: The general condition of 8 week age male C57BL/6J mice was recorded after 8 weeks of treatment with dexamethasone (DEX) and YGJ. Bone-related parameters and bone morphology were determined by Micro-CT. HE staining was used to observe the pathological changes of bone tissue. Serum levels of bone metabolism markers were detected by ELISA. Liver metabolomics analysis was conducted to search for the significant markers of anti-GIOP of YGJ and the metabolic pathway affecting it. RESULTS: After treatment, YGJ significantly reversed the weight loss caused by DEX; increase the number of bone trabecular in ROI region, significantly improve the bone-related parameters of GIOP mice, and increase the levels of alkaline phosphatase and osteocalcin. In the study of metabolic mechanism, YGJ reversed 24 potential markers in GIOP mice. These included cortisol, 3-hydroxybutyric acid, taurine, esculin and uric acid, which are closely associated with osteoporosis. Topological analysis results showed that YGJ had the most significant effect on taurine and hypotaurine metabolism, with - log10 (P) > 2.0 and Impact > 0.4. CONCLUSIONS: Yi-Guan-Jian decoction can increase bone density and improve bone microstructure by regulating the levels of alkaline phosphatase and osteocalcin and reverse bone loss in GIOP mouse model. The underlying metabolic mechanism may be related to taurine and hypotaurine metabolic pathway.

Interactive network pharmacology and electrochemical analysis reveals electron transport-mediating characteristics of Chinese medicine formula Jing Guan Fang.

Background: Jing Guan Fang (JGF) is an anti-COVID-19 Chinese Medicine decoction comprised of five medicinal herbs to possess anti-inflammatory and antiviral properties for treatment. This study aims to electrochemically decipher the anti-coronavirus activity of JGF and show that microbial fuel cells may serve as a platform for screening efficacious herbal medicines and providing scientific bases for the mechanism of action (MOA) of TCMs. Methods: Electrochemical techniques (e.g., cyclic voltammetry) and MFCs were adopted as the bioenergy-based platforms to assess the bioenergy-stimulating characteristics of JGF. Phytochemical analysis correlated polyphenolic and flavonoid content with antioxidant activity and bioenergy-stimulating properties. Network pharmacology on the active compounds was employed to identify anti-inflammatory and anti-COVID-19 protein targets, and molecular docking validated in silico results. Significant findings: This first-attempt results show that JGF possesses significant reversible bioenergy-stimulation (amplification 2.02 ± 0.04) properties suggesting that its antiviral efficacy is both bioenergy-steered and electron mediated. Major flavonoids and flavone glycosides identified by HPLC (e.g., baicalein and baicalin, respectively) possess electron-shuttling (ES) characteristics that allow herbal medicines to treat COVID-19 via (1) reversible scavenging of ROS to lessen inflammation; (2) inhibition of viral proteins; and (3) targeting of immunomodulatory pathways to stimulate the immune response according to network pharmacology.

[Professor GUAN Ling's clinical experience in treating knee osteoarthritis with structure-based medical acupuncture].

This paper summarizes professor GUAN Ling's clinical experience in the treatment of knee osteoarthritis (KOA) with structure-based medical acupuncture (SMA). Based on anatomy and biomechanics and through accurate physical examination, SMA adjusts the mechanical imbalance of muscles to relieve KOA dysfunction, and releases nerve compression to attenuate pain symptoms of KOA. In reference to traditional acupoint selection, and in association with painful areas and mechanical deduction, ashi points located at the rectus femoris, vastus intermedius, vastus medialis and vastus lateralis muscles, etc. are specially stimulated with acupuncture; and the rehabilitation training and health education are the adjuvant treatment for the patients.

The Traditional Chinese Medicine Formula Jing Guan Fang for Preventing SARS-CoV-2 Infection: From Clinical Observation to Basic Research.

COVID-19 is a global epidemic. Developing adjuvant therapies which could prevent the virus from binding to cells may impair viral infection. This study produces a traditional Chinese medicine formula, Jing Guan Fang (JGF), based on ancient medical texts, and examines the efficacy and the mechanism by which JGF prevents viral infections. JGF reduces COVID-19 like symptoms. Functional studies show that JGF inhibits the formation of syncytium and reduces the formation of viral plaque. JGF is not toxic in vitro and in vivo. Mechanistically, JGF induces lysosomal-dependent ACE2 degradation and suppresses mRNA and the protein levels of TMPRSS2 in human lung WI-38 and MRC-5 cells. Mice that inhale JGF exhibit reduced ACE2 and TMPRSS2 protein levels in lung tissues. Together, these findings suggest that JGF may improve the COVID-19 like symptoms and inhibit viral infection. Moreover, JGF may be applicable as an adjuvant preventive strategy against SARS-CoV-2 infection in addition to the use of vaccines.

More Parental Guan, More Academic Engagement? Examining the Moderating Roles of Adolescents' Gender and Reciprocal Filial Piety.

In the field of child development, although prior research has extensively documented the association between parenting styles and academic engagement, little is known from the perspective of the culture-specific parenting style in Eastern countries such as China, guan (i.e., intensively rear and strictly discipline). Moreover, individual differences, such as gender-specific patterns and the role of reciprocal filial piety, of this association are less explored. Guided by the socioecological framework, the present study examines the associations of parental guan with academic engagement, and the moderating roles of adolescents' gender and reciprocal filial piety. A total of 1808 Chinese adolescents (M age = 12.64 years, SD = 1.51; 51.4% girls) completed self-report questionnaires. Results showed that paternal guan and maternal guan were each positively associated with academic engagement. Moderation analyses showed that high reciprocal filial piety significantly enhanced the positive association between paternal guan and academic engagement for boys, but not for girls; however, the association between maternal guan and academic engagement has not been altered by reciprocal filial piety or gender. In conclusion, both paternal and maternal guan significantly contribute to adolescents' academic engagement, and such an association between paternal guan and academic engagement is differentiated by adolescents' gender and reciprocal filial piety.

Asian "Guan" Parenting and Life Satisfaction Among Adolescents in Malaysia: The Mediating Role of Filial Piety.

Literature on adolescent development has shown that parenting practices have positive relationships with adolescents' life satisfaction. Adolescents' life satisfaction improves when they have parents low in psychological control who uphold reciprocal self-disclosure in their communication. Guan parenting was found to correlate positively with adolescents' development. Therefore, it is methodologically important to replicate the investigation on the relationship between adolescents' life satisfaction and Guan parenting. Literature suggests that filial piety is shaped by parenting practices and adolescents who perceived intense parental concern, care, and involvement tend to uphold filial piety and express gratitude toward parents which may promote the adolescents' life satisfaction. In this study, mediation analysis was done to elucidate the relationship among parents' guan parenting style, filial piety, and life satisfaction on 606 adolescents (Mage=15.07; SDage=1.03; 52.1% females) in Malaysia. The adolescents were sampled through cluster sampling, and data were collected using self-administered questionnaires. The results showed positive relationship between paternal and maternal guan parenting with filial piety and adolescents' life satisfaction. Greater parents' filial piety was linked to higher life satisfaction among adolescents. Findings from the mediation models indicated the association among guan parenting with filial piety, gratitude toward parents, and higher life satisfaction. The findings also offered empirical evidence to the underlying mechanism of how guan parenting could affect adolescent life satisfaction via the mediating role of filial piety. The findings also supported the importance of culture-infused parenting in inculcating adolescents' filial piety besides establishing its link to life satisfaction in Asian families.

The Efficacy Comparison Between Guan-Fu Base A Hydrochloric Injection vs. Propafenone Hydrochloric Injection in the Treatment of Arrhythmia: Systemic Review and Meta-Analysis.

Objective: To determine using a systematic assessment and meta-analysis if GFA injection is an appropriate substitute of propafenone for arrhythmic. Design: Conduct a systematic review and meta-analysis of randomized controlled trials. Data Source: PubMed, Web of Science, Cochrane Library, Embase, Wan-Fang Database, VIP, CNKI, and Sino Med from their inception to 7 March 2021. Eligibility Criteria for Selecting Studies: Inclusion of randomized controlled trials, which draws a comparison between GFA and propafenone. Evaluation of study integrity and conducted an extraction of independent data. Main Outcome Measure: Efficacy for supraventricular tachycardia, it is considered effective if it is reversed within 40 min (without considering recurrence); for premature ventricular beats, if they are reduced by more than 50% within 6 h. Results: Included in this current study are 1,294 research subjects pooled from 14 clinical studies. From the pooled assessment, GFA is demonstrated to be the equivalent of propafenone regarding the potency of effectiveness for tachycardia (RR = 1.11, 95% CI: 0.96, 1.28, P = 0.15). The subset analysis indicated that GFA has a better effect on premature ventricular beats (RR = 1.35, 95% CI: 1.07, 1.70, P = 0.01) and a similar effect on supraventricular tachycardia (RR = 1.07, 95% CI: 0.98, 1.12, P = 0.21). GFA effectiveness is lesser than propafenone in the case of mean converting time (WMD = -1.18, 95% CI: -2.30, -0.07, P = 0.04), systolic blood pressure (WMD = -3.53, 95% CI: -6.97, -0.09, P = 0.04), and QRS complex (WMD = -3.82, 95% CI: -6.96, -0.69, P = 0.02). Both GFA and propafenone have identical effects for diastolic blood pressure, heart rate, P-R interval, and QTc interval. Conclusion: A meta-analysis of RCTs was performed across 14 clinical trials, whereby 1,294 patients are used as research subjects. From the results, it is revealed that the effect exhibited by GFA injection is similar to the propafenone injection when treating premature ventricular beats or supraventricular tachycardia. Nevertheless, in certain academic disciplines, it was found that GFA is safer and beneficial compared to propafenone. Based on facts from relevant studies, GFA is deemed applicable during clinical practice. Systematic Review Registration: https://www.inplasy.com/inplasy-2021-3-0077/, identifier: INPLASY202130077.

Guan Xin Dan Shen formulation protects db/db mice against diabetic cardiomyopathy via activation of Nrf2 signaling.

Guan Xin Dan Shen formulation (GXDSF) is a widely used treatment for the management of coronary heart disease in China and is composed of three primary components: Dalbergiae odoriferae Lignum, Salviae miltiorrhizae Radix et Rhizoma and Panax notoginseng Radix et Rhizoma. However, the potential use of GXDSF for the management of diabetic cardiomyopathy (DCM) has not been previously assessed. The present study aimed to assess the effects of GXDSF on DCM, as well as the underlying mechanism. In the present study, db/db mice were used. Following treatment with GXDSF for 10 weeks, fasting blood glucose, insulin sensitivity, serum lipid levels and cardiac enzyme levels were detected. Cardiac pathological alterations and cardiac function were assessed by performing hematoxylin and eosin staining and echocardiograms, respectively. TUNEL assays were conducted to assess cardiomyocyte apoptosis. Additionally, reverse transcription­quantitative PCR and western blotting were performed to evaluate the expression of apoptosis­associated genes and proteins, respectively. In the model group, the db/db mice displayed obesity, hyperlipidemia and hyperglycemia, accompanied by noticeable myocardial hypertrophy and diastolic dysfunction. Following treatment with GXDSF for 10 weeks, serum triglyceride levels were lower and insulin sensitivity was enhanced in db/db mice compared with the model group, which indicated improvement in condition. Cardiac hypertrophy and dysfunction were also improved in db/db mice following treatment with GXDSF, resulting in significantly increased left ventricular ejection fraction and fractional shortening compared with the model group. Following treatment with metformin or GXDSF, model­induced increases in levels of myocardial enzymes were decreased in the moderate and high dose groups. Moreover, the results indicated that, compared with the model group, GXDSF significantly inhibited cardiomyocyte apoptosis in diabetic heart tissues by increasing Bcl­2 expression and decreasing the expression levels of Bax, cleaved caspase­3 and cleaved caspase­9. Mechanistically, GXDSF enhanced Akt phosphorylation, which upregulated antioxidant enzymes mediated by nuclear factor erythroid 2­related factor 2 (Nrf2) signaling. Collectively, the results of the present study indicated that GXDSF attenuated cardiac dysfunction and inhibited cardiomyocyte apoptosis in diabetic mice via activation of Akt/Nrf2 signaling. Therefore, GXDSF may serve as a potential therapeutic agent for the management of DCM.

Study of the Mechanism of Action of Guanxin Shutong Capsules in the Treatment of Coronary Heart Disease Based on Metabolomics.

Background: Guan-Xin-Shu-Tong capsule (GXSTC) is a traditional Chinese medicine (TCM) that has been used to treat coronary heart disease (CHD) for many years in China. However, the holistic mechanism of GXSTC against CHD is still unclear. Therefore, the purpose of this paper was to systematically explore the mechanism of action GXSTC in the treatment of CHD rats using a metabolomics strategy. Methods: A CHD model was induced by ligation of the left anterior descending coronary artery (LAD). In each group, echocardiography was performed; the contents of creatine kinase (CK), lactate dehydrogenase (LDH) and aspartate transaminase (AST) in serum were determined; and the myocardial infarct size was measured. The metabolites in plasma were analyzed by UHPLC-MS/MS-based untargeted metabolomics. Then, multivariate statistical analysis was performed to screen potential biomarkers associated with the GXSTC treatment in the LAD-induced rat CHD model. Finally, the MetaboAnalyst 4.0 platform was used for metabolic pathway enrichment analysis. Results: GXSTC was able to regulate the contents of CK, LDH and AST; restore impaired cardiac function; and significantly reduce the myocardial infarction area in model rats. Twenty-two biomarkers and nine metabolic pathways of GXSTC in the treatment of CHD were identified through UHPLC-MS/MS-based untargeted metabolomics analysis. Conclusion: GXSTC regulates metabolic disorders of endogenous components in LAD-induced CHD rats. The anti-CHD mechanism of GXSTC is mainly related to the regulation of amino acid, lipid and hormonal metabolism. This study provides an overall view of the mechanism underlying the action of GXSTC against CHD.

Retrospective Reports of Perceived 'Guan' Parenting: Relationships to Adult Attachment Styles, Emotion Regulation, and Self-Esteem.

To determine how parental guan is related to social-emotional development in adulthood and how demographic controls might influence the prediction of parental guan on social-emotional development, 176 adults completed a series of questionnaires. We expected that both maternal and paternal guan would be positively related to secure attachment in adulthood, emotion regulation, self-esteem, and social self-esteem, but negatively related to avoidance and anxious attachment in adulthood. Pearson correlations largely supported these expectations. Moreover, the results of hierarchical regression analyses indicated that paternal guan was positively related to self-esteem but negatively related to anxious attachment in adulthood. Maternal guan, on the other hand, significantly predicted emotion regulation. Both maternal and paternal guan were significantly related to secure adult attachment and social self-esteem. Age, gender, and family structure contributed additional variance in some variables. We discuss our results in terms of the protective role of guan parenting in a child's life.

The mechanism of enriched environment repairing the learning and memory impairment in offspring of prenatal stress by regulating the expression of activity-regulated cytoskeletal-associated and insulin-like growth factor-2 in hippocampus.

BACKGROUND: Prenatal stress can cause neurobiological and behavioral defects in offspring; environmental factors play a crucial role in regulating the development of brain and behavioral; this study was designed to test and verify whether an enriched environment can repair learning and memory impairment in offspring rats induced by prenatal stress and to explore its mechanism involving the expression of insulin-like growth factor-2 (IGF-2) and activity-regulated cytoskeletal-associated protein (Arc) in the hippocampus of the offspring. METHODS: Rats were selected to establish a chronic unpredictable mild stress (CUMS) model during pregnancy. Offspring were weaned on 21st day and housed under either standard or an enriched environment. The learning and memory ability were tested using Morris water maze and Y-maze. The expression of IGF-2 and Arc mRNA and protein were respectively measured by using RT-PCR and Western blotting. RESULTS: There was an elevation in the plasma corticosterone level of rat model of maternal chronic stress during pregnancy. Maternal stress's offspring exposed to an enriched environment could decrease their plasma corticosterone level and improve their weight. The offspring of maternal stress during pregnancy exhibited abnormalities in Morris water maze and Y-maze, which were improved in an enriched environment. The expression of IGF-2, Arc mRNA, and protein in offspring of maternal stress during pregnancy was boosted and some relationships existed between these parameters after being exposed enriched environment. CONCLUSIONS: The learning and memory impairment in offspring of prenatal stress can be rectified by the enriched environment, the mechanism of which is related to the decreasing plasma corticosterone and increasing hippocampal IGF-2 and Arc of offspring rats following maternal chronic stress during pregnancy.

The Initial Stage of Neurosurgery in China: Contributions from Peking Union Medical College Hospital.

Modern neurosurgery has been developing worldwide for more than a century, whereas in China, as stated in previous literature, only 7 decades have passed since the development of neurosurgery during the early 1950s after World War II and China's War of Liberation. However, as increasing evidence before the wars from medical records, annual hospital reports, and journal archives emerge, the history of neurosurgery in China, especially the initial stage, needs to be reassessed. The establishment of the Peking Union Medical College Hospital (PUMCH) in 1921, funded by the Rockefeller Foundation, marked the start of Western medicine in China. Meanwhile, modern neurosurgery started to take root in the nation. Chinese neurosurgeons at PUMCH, Song-Tao Guan, M.D. and Yi-Cheng Zhao, M.D., both of whom graduated from PUMC and received further training abroad, made great contributions to the initial growth of Chinese neurosurgery. Although neurosurgery experienced slow and even stagnant development in China during the wars that took place from 1941-1949, the prewar period from 1921-1940 witnessed substantial improvement in operative skills, bedside education, resident training, and scientific research in neurosurgery at PUMCH, providing indispensable contributions that have allowed Chinese neurosurgery to flourish during the past 7 decades.

Polyphenols extract from lotus seedpod (Nelumbo nucifera Gaertn.): Phenolic compositions, antioxidant, and antiproliferative activities.

Seedpod, the nonedible portion of lotus (Nelumbo nucifera Gaertn.), was reported to be rich in polyphenols. The objective of this study was to investigate the major bioactive polyphenols of the lotus seedpods. The total polyphenol content (TPC) from ethanol extract of lotus seedpod (PELS) was found to be 34.23 µg gallic acid equivalents (GAE)/mg extract. Four polyphenolic compounds were identified in the PELS, comprised of one flavan-3-ol (catechin) and three flavonoids (kaemferol, quercetin and hyperoside). In vitro antioxidant and antiproliferative properties of the PELS were evaluated. PELS exhibited 89.38%, 99.82%, 68.25%, and 95.82% scavenging activities against 2,2-diphenyl-1-picrylhydrazyl (DPPH), superoxide, hydroxyl, and 2,2'azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radicals, respectively, at 1.6 mg/ml. The Fe3+ reducing power of PELS was 0.605 at 0.32 mg/ml, which is comparable to glutathione (GSH). The PELS showed 31.79% metal chelating capacity and 87.79% inhibition of linoleic acid auto-oxidation at 1.6 mg/ml. PELS showed cytotoxicity toward HepG2 and LNcap cell lines in vitro with IC50 values at 44.59 and 11.50 µg/ml, respectively. The findings of this study provide evidences that the inedible lotus seedpod could be a source for natural antioxidants and anticancer agents.

Influence of social stress on value of minimal anesthetic concentration of isuflurano in guan (Penelope obscura) captured in wildlife / Influência do estresse social sobre o valor da concentração anestésica mínima de isuflurano em jacus (Penelope obscura) capturados em vida livre

This study aimed to determine and evaluate whether there are differences in values of MAC in wildlife captured guan (Penelope obscura) under different conditions of social stress. This study used 27 bird species guan (P. obscura), divided into two groups: animals kept in the same enclosure (Collective Group) and animals kept in individual cages (Individual Group). The research was conducted at the Advanced Research Base of IBAMA, Painel/SC, and at the Clinical Veterinary Hospital of the "Universidade do Estado de Santa Catarina", Lages/SC. The birds were captured using network trap with manual disarmament and transported to the Veterinary Hospital in cages. The animals were fasted for 2 to 6 hours before the procedure; anesthetic induction was performed with isoflurane for instrumentation. The isoflurane CAM was placed in the target value 1.3v% in the first animal of each group, and waited 15 minutes for the nociceptive (electric) stimulus, in the value of 50 hertz and 50mA, held in faradic form (3 consecutive simple stimuli, followed by 2 continuous stimuli). The stimulus was performed on the lateral side of the left pelvic limb in the tibiotarsal region, and the electrodes were fixed with a 22G needle at a distance of 5cm between them. The bird's responses to the stimulus were considered positive (wing movements, head or vocalization) or negative (not presented movements of wings, head or vocalization) and the MAC value of the animal was recorded. Negative responses reduced next birds' MAC value by about 10%, and MAC positive responses increased by about 10%. Statistical analysis was done by methods up and down and analyze quantal for MAC and paired t-test for equivalent or t-test for variances not equal variances for the physiological variables. At the end of the experiment, the birds were reintroduced in the same capture area. The MAC value of isoflurane in the Collective Group was 1.4v% and the Individual Group 1.9v% to 0.903atm. It is observed that guan (P. obscura) in the Collective Group showed lesser anesthetic resistance to isoflurane than the birds in the Individual Group, showing that some levels of social stress can influence the MAC values of the isoflurane.(AU)

Este estudo teve como objetivo determinar e avaliar se há diferença nos valores de CAM em jacus (Penelope obscura) capturados em vida livre e submetidos a diferentes condições de estresse social. Foram utilizadas 27 aves da espécie jacu (P. obscura) de vida livre, que depois de capturados foram alocados em dois grupos: 10 animais que permaneceram em grupo no mesmo recinto (Grupo Coletivo) e 17 animais que permaneceram em gaiolas individuais (Grupo Individual). A pesquisa foi realizada na Base de Pesquisa Avançada do IBAMA, Painel/SC, e no Hospital de Clínica Veterinária da Universidade do Estado de Santa Catarina, Lages/SC. A captura foi realizada utilizando armadilha de rede com desarmamento manual e as aves foram transportadas para o Hospital Veterinário em gaiolas. Os animais foram submetidos a um jejum alimentar de 2 a 6 horas antes do procedimento, a indução anestésica foi realizada com isoflurano para instrumentação. A CAM de isoflurano foi colocada no valor alvo 1,3v% no primeiro animal de cada grupo, e esperado 15 minutos para realização do estímulo nociceptivo (elétrico), no valor de 50 hertz e 50mA, realizado de forma farádica (3 estímulos simples consecutivos, seguidos de 2 estímulos contínuos). O estímulo foi realizado na face lateral do membro pélvico esquerdo na região tibiotársica, e os eletrodos fixados com agulha 22G a uma distância de 5cm entre elas. A resposta da ave ao estímulo foi considerada positiva (movimentos de asas, cabeça ou vocalização) ou negativa (não apresentou movimentos de asas, cabeça ou vocalização) e o valor de CAM do animal foi registrado. Para resultados negativos, a CAM da próxima ave foi reduzida em torno de 10%, para positivos a CAM foi aumentada em torno de 10%. A análise estatística foi feita pelos métodos up and down e análise quantal para a CAM e teste t de pareado para variâncias equivalentes ou teste t para variâncias não equivalentes para as variáveis fisiológicas. Ao final do experimento as aves utilizadas foram reintroduzidas na mesma área de captura. O valor da CAM de isoflurano no Grupo Coletivo foi de 1,4v% e no Grupo Individual a CAM de 1,9v% a 0,903atm, sendo o valor do Grupo Coletivo significativamente menor que o Grupo Individual. Observa-se assim que os jacus (P. obscura) que permaneceram em recinto coletivo apresentaram uma menor resistência anestésica ao isoflurano que as aves que permaneceram em recintos individuais, mostrando que alguns níveis de estresse social como os observados aqui podem influenciar sobre os valores da CAM do isoflurano.(AU)

Perceived parental guan and school adjustment among Chinese early adolescents: The moderating role of interdependent self-construal.

INTRODUCTION: Previous research suggests that supportive parenting is positively related to adolescents' academic and psychological functioning. However, most extant research has focused on parenting styles observed in Western countries, whereas less is known about the role of culturally specific parenting dimensions in Eastern countries such as China. The purpose of this study was to examine the association between parental guan and school adjustment in Mainland Chinese early adolescents, postulating moderation by interdependent self-construal (ISC). METHODS: Participants were 148 early adolescents (48.6% girls) aged between 10 and 13 years, who completed a questionnaire survey. Teachers rated their students' school-related social competence, while academic grades were obtained from school records. RESULTS: Linear regression models controlling for age, gender, and socioeconomic status showed that maternal guan was positively associated with social competence. Furthermore, ISC moderated the link between maternal guan and school adjustment. Specifically, high levels of ISC were found to enhance the positive relation between perceived maternal guan and both social competence and academic performance. However, no significant associations were found for paternal guan. CONCLUSIONS: Our findings extend prior research by documenting the positive role of guan parenting style and ISC in early adolescents' school adjustment, and underscore the centrality of mothers in the childrearing process within Chinese families.

[Effects of balanced fertilization on growth and fruit quality of 'Huang-guan' pear on desert area.] / å¹³è¡¡æ–½è‚¥å¯¹è’æ¼ åŒºé»„å† æ¢¨ç”Ÿé•¿ä¸Žå“è´¨çš„å½±å“.

A field experiment was carried out to study the effects of balanced fertilization on growth and development, yield, fruit quality and mineral content in 'Huang-guan' pear to provide a theoretical basis for the reasonable level of fertilization in pear orchards. Four treatments were arranged with 12-year old 'Huang-guan' pear trees from the same orchard: conventional fertilization (CK), low levels of N, P2O5 and high level of S (T1), medium levels of N, P2O5 and S (T2), high levels of N, P2O5 and low level of S (T3). The results showed that different treatments had little effect on the growth and development of current-year branch and leaves in the first year. However, in the se-cond year, T1 treatment promoted the length and diameter of current-year branch by 16.2% and 11.4%, respectively. Continuous fertilization could increase the leaf mineral contents in different degrees. The contents of Cu, Fe, and Zn in leaves under T1 treatment, Mg and B in leaves under T2 treatment, and P and Mn in leaves under T3 treatment were highest. Different fertilization levels had no significant effect on yield but on fruit quality. The contents of soluble sugars and vitamin C (Vc) were significantly increased by T2 treatment, which was 4.2% and 7.1% higher than those in CK. However, T1 significantly decreased contents of total soluble solid, soluble sugars and Vc, while highest organic acid content presented in T3. Fruit Fe content was positively correlated with soluble sugar content and fruit shape index, but was negatively correlated with single fruit mass, organic acids and Vc. Fruit P content was positively correlated with fruit shape index and firmness, but was negatively correlated with contents of soluble sugars, organic acids and Vc. Accordingly, T2 could improve fruit quality and maintain the productivity, and thus should be the suitable fertilization strategy for the 'Huang-guan' pear management in desert area.
