OBJECTIVE To investigate the inhibitory effects of Ginkgo biloba extract （GBE） on renal inflammation in diabetic nephropathy （DN） model mice， and its potential mechanism. METHODS KK/Ay mice were fed with high fat and high sugar to induce DN model. They were divided into model group， positive control group [metformin 200 mg/（kg·d）]， GBE low-dose and high-dose groups [100， 200 mg/（kg·d）]， with 6 mice in each group. Six C57BL/6J mice were fed with a regular diet as the control group. Administration groups were given relevant liquid intragastrically， control group and model group were given constant volume of normal saline intragastrically， once a day， for 8 consecutive weeks. The body weight， fasting blood glucose， 24-hour food intake， 24-hour urine output， monocyte chemoattractant protein-1 （MCP-1）， interleukin-12 （IL-12）， IL-10， advanced glycation end products （AGEs）， blood urea nitrogen （BUN） and serum creatinine （Scr） of mice were measured， and the ratio of bilateral kidneys to body weight was also calculated. The pathological injury and fibrotic changes of the renal cortex were observed， and the expressions of macrophage polarization marker proteins [type M1： inducible nitric oxide synthase （iNOS）； type M2： arginase-1 （Arg-1）] and AGEs-the receptor of advanced glycation end products （RAGE）/Ras homolog gene pharm_chenjing@163.com family member A （RhoA）/Rho-associated coiled-coil forming protein kinase （ROCK） signaling pathway-related proteins were determined in renal cortex. RESULTS Compared with the model group， the symptoms such as renal cortical hyperplasia， vacuoles， infiltration of inflammatory cells， and renal cortical fibrosis had been improved in GBE low-dose and high-dose groups； body weight， serum level of IL-10， the expression of Arg-1 in the renal cortex were significantly higher than model group （P＜ 0.01）； fasting blood glucose， 24-hour food intake， 24-hour urine output， serum levels of MCP-1， IL-12， BUN， Scr and AGEs， the ratio of bilateral kidneys to body weight， renal injury score， the proportion of renal interstitial fibrosis， the protein expressions of iNOS， RAGE， RhoA and ROCK1 （except for GBE low-dose group） in renal cortex were significantly lower than model group （P＜0.01）. CONCLUSIONS GBE could improve kidney damage and alleviate inflammatory response in DN model mice， the mechanism of which may be related to inhibiting the AGEs-RAGE/RhoA/ROCK signaling pathway and regulating macrophage polarization.

Role of ripasudil as an adjunct treatment in the management of pseudoexfoliative glaucoma

Purpose: Ripasudil is a class of drug which alters the trabecular meshwork to increase the aqueous outflow and has been shown to be effective in pseudoexfoliative glaucoma (PXF G). This study aimed at assessing the efficacy and safety profile of ripasudil as an adjunct treatment in patients with PXF G at maximal tolerated antiglaucoma medications. Methods: In this prospective, interventional study, 40 patients with PXF G were enrolled between May 2021 and Jan 2022. Ripasudil 0.4% was started as an adjunctive drug to the ongoing antiglaucoma medications. On follow?up visits at 1, 3, and 6 months, the visual acuity, intraocular pressure (IOP), anterior segment, and fundus findings were evaluated. The premedication and postmedication IOP values were compared by paired t?test, and a P?value <0.05 was considered statistically significant. Results: Average age at recruitment was 60.02 ± 8.74 years. Baseline premedication IOP was 25.375 ± 3.276 mmHg. IOP reduction at 6 months was found to be statistically significant in all patients, with the maximal response being 24.13%. Also, 87.5% (35/40) of patients reached target IOP or even lower IOP at the end of study. There was no statistically significant association between the PXF grade and IOP. However, the grade of inferior iridocorneal angle pigmentation was found to be higher in eyes with elevated IOP (P < 0.05). Only three patients developed conjunctival hyperemia as an adverse reaction, which was mild and transient. Conclusion: Ripasudil showed additional IOP?lowering effect with other antiglaucoma medications and exhibited no significant side effects

Rock art: the body culture of movement before Brazil / Arte rupestre: a cultura corporal do movimento antes do Brasil / Arte rupestre: la cultura del cuerpo del movimiento antes de Brasil

This investigation discusses the relationship between the body culture of movement and two rock art scenes located in the Parque Nacional Serra da Capivara, (Serra da Capivara National Park) - PNSC, in the state of Piauí, Brazil. The scenes depict a flic flac and a human pyramid, which have been accepted in contemporaneity as gymnastics and acrobatics. An interdisciplinary theoretical apparatus based on Physical Education and its relationships with Archeology and Anthropology was used in the analysis. The analysis is based on inferences, as nothing guarantees that the hands that portrayed the scenes had the same intentions as the authors of the research. One of the findings understands that motor skills helped the daily demands of adversity for the survival of the group. In another point of view, based on the Ilinx concept, flic flac satisfies the search for a trance/vertigo vital to ritualistic liturgy, and the human pyramid serves the imperative task of consolidating cooperative bonds and trust between its members in a hostile environment. (AU)

A investigação discute as relações entre duas artes rupestres - flic flac e a pirâmide humana -, admitidas na contemporaneidade como ginástica e acrobacia, localizadas no Parque Nacional Serra da Capivara - PNSC, no Estado do Piauí, Brasil, e a cultura corporal do movimento. Utilizou-se de um aparato teórico interdisciplinar fundamentado na Educação Física e suas relações com a Arqueologia e Antropologia na análise. Trata-se de inferências, pois nada garante que as mãos que retrataram as cenas tinham a intencionalidade dos autores da pesquisa. Uma das ilações entende que as habilidades motoras auxiliavam as demandas do cotidiano de adversidades para sobrevivência do grupo. Por outro prisma, a partir do conceito de Ilinx, o flic flac atende a busca de um transe/vertigem vital a liturgia ritualística, e, a pirâmide humana serve a imperiosa tarefa de consolidar os laços cooperativos e de confiança entre os seus membros em um ambiente hostil.

Prevalence and diversity of ectoparasites in Wild Rock Pigeon (Columba livia) in Punjab region, Pakistan / Prevalência e diversidade de ectoparasitas em Wild Rock Pigeon (Columba livia) na região de Punjab, Paquistão

Abstract The current study was carried out to estimate the prevalence and diversity of ectoparasites in rock pigeons in different regions of Punjab, Pakistan. A total of 120 birds were captured from March 2017 to February 2019. The ectoparasites were collected by standard procedures and preserved in 70% ethanol containing one drop of glycerin. Data related to age, health status, sex, type of area, sampling location and season were collected using a standardized form. Ectoparasites were identified based on morphological characteristics by using identification keys. Ninety-six (80%) birds were infested with ectoparasites. A total of seven families and thirteen species of different ectoparasites were observed. Mainly, seven species of lice, two species of flies, one species of tick and three species of mites were recovered from infested birds. The female pigeons were more often infested (89.02%) than male pigeons (60.52%). The prevalence was found higher during summer (100%) as compared to other seasons. The infestation rate was higher in Industrial area (97.50%) as compared to other regions. The highest prevalence of ectoparasites (100%) was recorded from Sargodha district. There was significant (P < 0.05) variation among number of ectoparasites on wing, chest, tail and neck within age groups, seasons and ecological zones. The occurrence of parasites in relation to area, age, health status, sex and season were significant. The infestation rate of parasites in rock pigeon is high in different districts of Punjab. It is recommended that these wild birds infested with multiple species of ectoparasites could be the potential source of infestations in domesticated birds if they come in contact with them. The contact of domesticated birds should be prevented from wild birds to minimize the chance of cross species transmission of ectoparasites.

Alleviation of isoproterenol-induced myocardial fibrosis in mice by autophagy regulated by Astragaloside Ⅳ through activating ROCK/JNK pathway / 药学实践杂志

Objective To investigate the effect and mechanism of astragaloside Ⅳ(AS-Ⅳ) activating ROCK/JNK to regulate autophagy in improving isoproterenol (ISO) induced myocardial fibrosis (MF) in mice. Methods The mice were randomly divided into control operation group (Control group), ISO induced myocardial fibrosis group (MF group), AS-Ⅳ treatment group (AS-Ⅳ group) and combination group of astragaloside IV and Y-33075 (ROCK inhibitor) (astragaloside IV+Y-33075 group). After repeated administration for 30 days. The serum levels of LDH, BNP, CTGF in each group were detected. The cardiac function was detected by ultrasound. Myocardial structure and tissue fibrosis degree in each group were detected by Sirius Red and Masson staining. Oxidative stress (ROS) levels in myocardial tissue of each group were detected by DHE staining and the expression of ROCK, JNK, Atg5, Beclin 1, and LC3 Ⅰ/Ⅱ in myocardial tissue were detected by Western blotting. Results Compared with AS-Ⅳ group, the EF value of AS-Ⅳ+Y-33075 group decreased and the degree of myocardial fibrosis increased (P<0.05). The serum level of LDH, BNP, CTGF increased and the level of ROS in myocardial tissue increased while the expression of ROCK, JNK, Atg5, Beclin 1, LC3 Ⅰ/Ⅱ decreased (P<0.05). Y-33075 could block the protective effect of AS-Ⅳ on myocardial injury induced by MF and inhibit the regulation of AS-Ⅳ on ROCK and JNK. Conclusion AS-Ⅳ could attenuate myocardial fibrosis in mice by activating ROCK/JNK signal and promoting autophagy.

Effects of the ROCK1 gene on proliferation and migration of and related molecular expression in keloid fibroblasts / 中华皮肤科杂志

Objective:To investigate effects of the ROCK1 gene on proliferation and migration of and related molecular expression in keloid fibroblasts.Methods:Immunohistochemical technique was used to detect ROCK1 protein expression in human keloids and normal skin tissues, and Western blot analysis was performed to detect the expression of ROCK1, transforming growth factor β1 (TGF-β1) and E-cadherin in keloid tissues. In vitro cultured human keloid fibroblasts (HKFs) were divided into 4 groups: ROCK1 gene overexpression control group (ROCK1 NC group) transfected with ROCK1 gene overexpression control vectors, ROCK1 gene overexpression group (ROCK1 OE group) transfected with ROCK1 gene overexpression vectors, ROCK1 gene knockdown control group (sh NC group) transfected with ROCK1 gene knockdown control vectors, and ROCK1 gene knockdown group (shROCK1 group) transfected with ROCK1 gene knockdown vectors. Cell counting kit-8 (CCK8) assay was performed to evaluate the effect of ROCK1 gene on the survival rate of HKFs, Transwell assay to evaluate the effect on the migration of HKFs, and real-time fluorescence-based quantitative PCR (qRT-PCR) and Western blot analysis were conducted to determine the mRNA and protein expression of ROCK1, TGF-β1 and E-cadherin, respectively. Results:Immunohistochemical study showed that ROCK1 protein expression decreased significantly in the human keloid tissues compared with the normal tissues ( t = 6.47, P = 0.003) ; Western blot analysis showed that the expression levels of ROCK1 and E-cadherin significantly decreased ( t = 14.02, 162.20, respectively, both P < 0.001), while TGF-β1 expression significantly increased ( t = 76.01, P < 0.001) in the keloid tissues compared with the expression levels of corresponding proteins in the normal tissues. CCK8 assay showed that the cell activity was significantly lower in the ROCK1 OE group than in the ROCK1 NC group after 24-hour transfection ( t = 3.25, 3.78, P = 0.031, 0.019, respectively), and significantly higher in the shROCK1 group than in the sh NC group ( t = 3.12, 2.79, P = 0.036, 0.049, respectively). Transwell assay showed that the number of migratory cells was significantly lower in the ROCK1 OE group than in the ROCK1 NC group ( t = 5.17, P = 0.004), and significantly higher in the shROCK1 group than in the sh NC group ( t = 9.28, P < 0.001). Compared with the ROCK1 NC group, the ROCK1 OE group showed significantly increased mRNA and protein expression levels of ROCK1 and E-cadherin ( P < 0.05 or < 0.001), but decreased mRNA and protein expression levels of TGF-β1 (both P < 0.001) ; compared with the sh NC group, the shROCK1 group showed significantly decreased mRNA and protein expression levels of ROCK1 and E-cadherin ( P < 0.05 or < 0.001), but significantly increased mRNA and protein expression levels of TGF-β1 ( P = 0.005 or < 0.001) . Conclusions:The ROCK1 gene can inhibit the proliferation and migration of HKFs. Overexpression of the ROCK1 gene can down-regulate the TGF-β1 gene expression and up-regulate the E-cadherin gene expression in HKFs.

Mechanism of Xiangsha Liujunzi Tang in Regulation of RhoA/ROCK2/MYPT1 Pathway to Improve Gastric Motility in Rats with Functional Dyspepsia / 中国实验方剂学杂志

ObjectiveTo explore the intervention mechanism of Xiangsha Liujunzi Tang in rats with functional dyspepsia （FD） based on the Ras homolog gene family member A （RhoA）/Rho-associated coiled-coil containing protein kinase 2 （ROCK2）/Myosin phosphatase target Subunit 1 （MYPT1） pathway. MethodSixty male SD suckling rats in SPF grades were randomly divided into blank group （n=10） and model group （n=50）. The comprehensive modeling method （gavage administration of iodoacetamide+exhaustion of swimming+disturbance of hunger and satiety） was used to replicate the rat model of FD. After successful replication of the model， the rats in the model group were randomly divided into model group， mosapride group， and high， middle， and low-dose Xiangsha Liujunzi Tang groups， with 10 rats in each group. Rats in the blank group and model group were given 10 mL kg-1·d-1 normal saline， those in the mosapride group were given 1.35 mg·kg-1·d-1 mosapride， and those in the high， middle， and low-dose Xiangsha Liujunzi Tang groups were given 12， 6， and 3 g·kg-1·d-1 Xiangsha Liujunzi Tang， respectively. The intervention lasted 14 days. The general living conditions of rats were observed before and after modeling and administration， and the 3-hour food intake and body mass of rats were measured. After intervention， the intestinal propulsion rate of rats was measured， and the pathological changes in the gastric tissue were observed by hematoxylin-eosin （HE） staining. The content of choline acetyl transferase （ChAT） and vasoactive intestinal peptide （VIP） in the medulla oblongata and gastric tissue homogenate was determined by enzyme-linked immunosorbent assay （ELISA）， the distribution of adenosine triphosphate （ATP） enzyme in gastric antrum smooth muscle was observed by frozen section staining， and the protein expression levels of RhoA， ROCK2， and phosphorylated-myosin phosphatase target subunit 1 （p-MYPT1） in the gastric tissue were detected by Western blot. ResultCompared with the blank group， the model group had withered hair， lazy movement， slow action， poor general living condition， lower 3-hour food intake， body mass， and lower intestinal propulsion rate （P<0.05）， whereas no obvious abnormality in gastric histopathology. In the model group， the content of ChAT in the medulla oblongata and gastric tissue decreased， the content of VIP in gastric tissue increased， the distribution of ATP enzyme in gastric antrum smooth muscle decreased significantly， and the protein expression levels of RhoA， ROCK2， and p-MYPT1 in the gastric tissue decreased significantly （P<0.05）. As compared with the model group， the general living condition of rats in each intervention group was significantly improved， and the 3-hour food intake， body mass， and intestinal propulsion rate were significantly increased （P<0.05）. There was no significant difference in gastric pathology in the intervention groups. The content of ChAT in the medulla oblongata and gastric tissue increased significantly， the content of VIP in the gastric tissue decreased， the distribution of ATP enzyme in gastric antrum smooth muscle increased significantly， and the protein expression levels of RhoA， ROCK2， and p-MYPT1 in the gastric tissue increased significantly （P<0.05）. The intervention effect of Xiangsha Liujunzi Tang group on the above indexes was dose-dependent. ConclusionXiangsha Liujunzi Tang can effectively improve the general living condition and gastric motility of rats with FD， and its specific mechanism may be related to the activation of the RhoA/ROCK2/MYPT1 pathway in the gastric tissue to regulate smooth muscle relaxation and contraction and promote gastric motility.

The expression of RhoA membrane proteins, ROCK1, MMP-2, MMP-9 in the experimental group was significantly decreased compared with that in the negative control group and blank control group (P<0.05). Cell proliferation ability was significantly decreased (P<0.05). The migration and invasion abilities were significantly decreased (P<0.05). @*Conclusion @#In vitro silencing of ICMT gene can effectively inhibit the migration and invasion of human SACC-LM and SACC-83 cells, and the mechanism may be related to RhoA-ROCK signaling pathway.

Effect of Yishen Daluo Prescription on Rho/ROCK Signaling Pathway in EAE Mice Based on Silencing of β-arrestin1 / 中国实验方剂学杂志

ObjectiveTo investigate the effects of Yishen Daluo prescription （YSDL） on Ras homolog（Rho）/Rho-associated coiled-coil containing protein kinase（ROCK）signaling pathway in mice with experimental autoimmune encephalomyelitis （EAE） based on the silencing of β-arrestin1 gene. MethodSixty C57BL/6 female mice were randomly divided into a blank group， a model group， a virus group， a YSDL group， a virus + YSDL group， and a prednisone acetate group （hormone group）. The EAE model was induced in mice except for those in the normal group. Adeno-associated virus（AAV）solution （150 μL， 1×1011 vg·mL-1） was injected into the tail vein of each mouse in the virus group and the virus + YSDL group on the 4th day of immunization. Drugs were administered on the 8th day of modeling. Specifically， normal saline was given to the mice in the normal group，the model group，and the virus group at 10 mL∙kg-1， prednisone acetate suspension to those in the hormone group at 3.9 g∙kg-1，and YSDL to those in other groups at 20 g∙kg-1 for 14 consecutive days. The mice were weighed and scored every day. The neurological function scores of mice in each group were recorded every day after immunization. Hematoxylin-eosin （HE） staining was used to determine the inflammatory response and lesion location in the brain tissues and spinal cord tissues of mice. The protein expression of β-arrestin1，Ras homolog gene family member A（RhoA）， and Rho-associated coiled-coil forming protein kinase Ⅰ（ROCK Ⅰ） in spinal cord and brain tissues of EAE mice was determined by Western blot. ResultCompared with the model group， the virus group and the virus + YSDL group showed decreased neurological function scores （P<0.01），and the YSDL group also showed decreased neurological function scores（P<0.05）. HE results showed that there was obvious inflammatory reaction in the central nervous system （CNS） of the model group， which was alleviated to varying degrees in other groups compared with the model group. Western blot results showed that compared with the blank group， the model group showed increased protein expression levels of β-arrestin1， RhoA， and ROCK Ⅰ in the spinal cord tissues （P<0.01）. Compared with the model group， the virus group， the YSDL group， the virus + YSDL group， and the hormone group showed decreased protein expression levels of β-arrestin1， RhoA， and ROCKⅠ in the spinal cord tissues （P<0.01）. Compared with the blank group， the model group showed increased protein expression levels of β-arrestin1， RhoA， and ROCK Ⅰ in the brain tissues （P<0.01）. Compared with the model group， the virus group， the YSDL group， the virus + YSDL group， and the hormone group showed decreased protein expression level of β-arrestin1 in the brain tissues （P<0.01）， and the virus group and the YSDL group showed decreased protein expression levels of RhoA， and ROCKⅠ in the brain tissues （P<0.05）. Additionally， the virus + YSDL group and the hormone group showed decreased protein expression levels of RhoA and ROCKⅠ in the brain tissues （P<0.01）. ConclusionYSDL can improve the clinical symptoms of EAE mice and improve the inflammatory response of CNS. The mechanism is presumably attributed to the fact that YSDL inhibits the expression of β-arrestin1 in CNS，thereby reducing the expression of Rho/ROCK signaling pathway. Furthermore， YSDL may have a synergistic effect with the inhibition of β-arrestin1 gene expression.

VANISHING MOUNTAINS: A STUDY OF ILLEGAL MINING IN THE ARAVALLIS OF SOUTH-WESTERN DISTRICTS OF HARYANA AND ITS EFFECT ON THE PHYSICAL ENVIRONMENT AND HUMAN LIFE

Illegal mining activities have been rampant since decades. These activities have literally changed the face of the landscape. The mountains have disappeared, surface have been left dotted with deep mining pits, villagers have to live a substandard life due to the negative effects of mining in the form of decreased water quality, poor air quality, mining related accidents, damaged houses because of stone blasting and much more. The authorities have turned a blind eye towards the common man's problem and thus the residents of nearby villages are left with no choice but to live under silence. The unscientific and illegal mining practices in the south- west region of Haryana in the districts of Mehandargarh, Dadri and Bhiwani has altered the physical landscape and affected the socio cultural life of nearby villages to a great extent. The study is a step in the direction of describing how an anthropogenic activity if done without any rules and order and in unscientific manner can affect the environment to unimaginable

Ecology of Aedes vittatus (Diptera: Culicidae) in rock pools across agroecosystem in Northern Savanna, Nigeria

Background & objectives: This study focuses on modulating dexterity of some ecological variables of Aedes vittatus classically breeding in rocky habitats. The study provides a useful insight into ecological variables that underpin or hinder profuse breeding of Ae. vittatus in rock pools and its probable role in disease transmission. Methods: HANNA HI98129 pH/EC/TDS/TEMP meter was used in situ while standard protocols were used to determine other hydro-chemical variables. Aedes vittatus larvae were obtained with soup ladle and modified ladle dippers. D-frame net was used to capture macroinvertebrates while plankton net was used to obtain samples of microalgae. Tadpoles and water turtles were collected with fine mesh invertebrate net. Macrophytes were uprooted and identified at the Herbarium Unit, Department of Botany, Ahmadu Bello University, Zaria. The influence of physicochemical variables was correlated with distribution of Ae. vittatus using Principal Component Analysis. Regression and ANOVA were used to test for association between predictor variables and mosquito abundance and for the difference amongst inselbergs. Results: Linear larval density of Ae. vittatus in rock pools which tapered across Guinea savanna were obtained from twenty-one sites with average density of 139.6 in Sudan savanna. Guinea savanna had an average larval density of 75.5 with lower subsets of moving average densities compared to Sudan savanna. One hundred and sixty-one aquatic insects belonging to four insect orders cohabited rock pools with Ae. vittatus. Toads and frogs’ tadpoles were of Bufonidae and Pyxicephalidae families while water turtles belong to Emydidae. pH, TDS (ppm), EC (µs/cm) and alkalinity (mg/l) differed significantly (p<0.05) with the abundance of Ae. vittatus in rock pools. Temperature, depth, water hardness and total suspended solid had direct influence on the distribution of Ae. vittatus in rock pools across sites. Significant positive correlation exists between aquatic insects and abundance of Ae. vittatus. Hydroperiod length, concentration of nitrate and pH were determinants that leverage profuse breeding of Ae. vittatus and survival of rock pool biota. Interpretation & conclusion: Results revealed that the bearing influence of rock pool variables is inevitable for breeding of Ae. vittatus. A well defined measure of efficacy incorporating indigenous communities for sustained vector control on inselbergs will go a long way in decimating population of Ae. vittatus and limit the risk of spread of yellow fever hitherto areas not thriving.

Safety, efficacy, and patient selection of ripasudil in patients with uncontrolled glaucoma with maximum conventional medical therapy

Purpose: Ripasudil hydrochloride hydrate (0.4%) is the first Rho?associated protein kinase (ROCK) inhibitor eye drop that lowers intraocular pressure (IOP) by increasing conventional aqueous outflow through the trabecular meshwork and Schlemm’s canal. We aimed to evaluate the safety and efficacy of ripasudil in patients using the maximum topical anti?glaucoma medications and with uncontrolled IOP. Methods: In our prospective interventional study, we enrolled 27 eligible and consenting patients (46 eyes) who presented to us between January 2021 and June 2021. Ripasudil 0.4% was added as adjunctive therapy to the ongoing glaucoma treatment. On follow?up visits at 7 days, 15 days, 1 month, 2 months, and 3 months, the visual acuity, IOP with applanation tonometer, anterior segment, and fundus were evaluated. The IOP before and after the use of ripasudil eye drops was compared by paired t?test. Results: Among the 27 patients, 18 were males and 9 were females. A statistically significant reduction in IOP was noted at all time durations (P < 0.00001) with the maximum reduction at 3 months with all patients achieving their target IOP. No patient developed any side effects necessitating the omission of ripasudil. The most common adverse event noted was conjunctival hyperemia (22 patients), which was mild and transient. Conclusion: Ripasudil showed additional IOP?lowering effect with other antiglaucoma medications and exhibited no significant side effects.

Evaluation of the rs35996865 polymorphism of the ROCK1 gene in sepsis

SUMMARY OBJECTIVE: Sepsis is a complex and serious medical condition resulting from the activation of an innate host response to infections. The etiology of sepsis is complex and can be influenced by genetic susceptibility. The purpose of the present study was to investigate a possible association of Rho-kinase 1 (ROCK1) gene polymorphism with sepsis in a Turkish population. METHODS: The study group consisted of 100 unrelated patients with sepsis and 100 healthy controls. Genomic DNA was isolated from peripheral leukocytes from EDTA-containing blood using the QIAamp DNA Blood Mini Kit. ROCK1 gene rs35996865 and rs112130712 (Lys1054Arg) polymorphisms were analyzed in genomic DNA using the LightCycler 480 II real-time polymerase chain reaction. RESULTS: There were no significant differences in allele and genotype frequencies for ROCK1 gene rs35996865 polymorphism between the patients with sepsis and control group (p>0.05). Additionally, no association was detected between the rs35996865 polymorphism and mortality in the patient group. No polymorphism was detected with ROCK1 gene rs112130712 (Lys1054Arg) in our study groups. CONCLUSIONS: Our data showed that there is no marked association between the rs35996865 polymorphism and sepsis. Therefore, these results suggest that ROCK1 gene rs35996865 polymorphism is not risk factor for the development of sepsis in the Turkish population.

Body asymmetries in dancers of different dance disciplines / Asimetrías corporales en bailarines de diferentes disciplinas de baile

SUMMARY: Dance is an attractive sport discipline in which participation is increasing every year, unfortunately, the prevalence of injuries is also increasing. Various dance disciplines and dance techniques require body control, often in extreme anatomical positions that place a heavy strain on the musculoskeletal system. The aim of this research was to analyze body asymmetries of four different dance disciplines (standard and Latin American dance - STLA, acrobatic rock and roll - RNR, breakdance - BD and hip hop - HH), by using anthropometric (InBody 720; Biospace Co., Ltd) and 3D body measurements (NX-16; TC2) to establish possible later discomforts and injuries. T-test was performed to find differences between left and right extremities in all four dance disciplines. Results of the study showed that asymmetries are present in all of the studied dance disciplines. When comparing dance disciplines, we found out that STLA dancers are the most prone to develop body asymmetries (six out of nine paired variables), mainly because of the closed position. The position itself is the asymmetry and in which dancers remain for a very long time while training the technique of each dance. As dance is known for its asymmetrical movement of the body and it is expected that some of the asymmetries will appear after a few years of training. For a better understanding of possible consequences of asymmetries in dancers' bodies, further and more detailed analysis within each dance discipline is required.

RESUMEN: El baile es una disciplina deportiva atractiva cuya participación aumenta cada año, sin embargo también aumenta la prevalencia de lesiones. Varias disciplinas de baile y las técnicas de baile requieren el control del cuerpo en posiciones anatómicas extremas las cuales ejercen una gran presión sobre el sistema musculoesquelético. El objetivo de esta investigación fue analizar las asimetrías corporales de cuatro disciplinas de baile diferentes (baile estándar y latinoamericano - STLA, rock and roll acrobático - RNR, breakdance - BD y hip hop - HH), utilizando técnicas antropométricas (InBody 720; Biospace Co., Ltd) y mediciones corporales en 3D (NX-16; TC2) para establecer posibles molestias y lesiones posteriores. Se realizó la prueba T para determinar diferencias entre los miembros izquierdo y derecho en las cuatro disciplinas de baile. Los resultados de este estudio mostraron que las asimetrías se encontraron en todas las disciplinas de baile. Al comparar las disciplinas de baile, descubrimos que los bailarines de STLA son los más propensos a desarrollar asimetrías corporales (seis de nueve variables pareadas), principalmente debido a la posición cerrada. La posición en sí es asimétrica y en la que los bailarines permanecen durante mucho tiempo mientras entrenan la técnica de cada baile. Como el baile es conocido por el movimiento asimétrico del cuerpo, es posible que algunas de las asimetrías aparezcan después de algunos años de entrenamiento. Se requiere un análisis más profundo y detallado dentro de cada disciplina de danza para una mejor comprensión de las posibles consecuencias de las asimetrías en los cuerpos de los bailarines.

Fasudil alleviates lung injury via targeting Rhoa/ROCK signal pathway in septic mice / 中华急诊医学杂志

Objective:To determine the protective effect of fasudil on acute lung injury in septic mice.Methods:Forty-five 4-6-week-old male C57BL mice were randomly(random number) assigned to three groups ( n=15 each group): control group, lipopolysaccharide (LPS) group and Fasudil intervention group (FAS+LPS). Acute lung injury model of septic mice was established with an intraperitoneal injection and intratracheal infusion of LPS. The mice in the FAS+LPS group were injected with fasudil hydrochloride intraperitoneally 30 min before intraperitoneal LPS injection and 1 h after intratracheal LPS infusion, respectively. All mice were sacrificed at 4 h after modeling, and lung tissues were collected. Hematoxylin-eosin staining was preformed to observe the morphological changes in the lung tissue. The wet /dry weight (W/D) ratio, malondialdehyde (MDA) content and the activity of myeloperoxidase (MPO) in the lung tissues were detected. Caspase-3 expression was examined by immunohistochemical (IHC) staining. Western blot was employed to detect the expression of RhoA, ROCK1, endothelial nitric oxide synthase (eNOS), and p-eNOS. Results:Inflammatory cell infiltration and erythrocyte exudation were significantly reduced, and the degree of interstitial oedema and derangement of alveolar structure appeared in a decreasing degree after FAS intervention. Compared with the LPS group, the W/D ratio, MDA content, MPO activity and the expression of Caspase-3 in the FAS+LPS group were significantly reduced (all P<0.01). Meanwhile, the expression of RhoA and ROCK1 of the LPS group were obviously higher than those in the control group ( P<0.05), and p-eNOS was obviously lower than that in the control group ( P<0.05). Furthermore, the expression of RhoA and ROCK1 of the FAS+LPS group were obviously lower than those in the LPS group, and p-eNOS was obviously higher than that in the LPS group. There was no significant difference on the expression of eNOS among the three groups. Conclusions:Fasudil can alleviate the degree of inflammatory cell infiltration, reduce apoptosis in lung tissue, inhibit the RhoA/ROCK1 signaling activity, and promote the phosphorylation expression of eNOS in septic mice.

Objective:To observe the effect of astragaloside Ⅳ on lysophosphatidic acid(LPA)- induced neurite retraction of N1E-115 cells and its potential mechanism.Methods:N1E-115 cells were divided into blank group, model group, the low, medium and high dose groups of astragaloside Ⅳ. The blank group and model group was not intervened by astragaloside; while the low, medium and high dose groups were treated with 20,40 and 80 μg/ml astragaloside Ⅳ for 24 h. Each group was cultured with serum-free medium for 12 h. The model group and astragaloside Ⅳ groups were intervened by 40 μmol/L LPA for 10 min. Each group was observed and photographed with the inverted microscope, and the number of neurites in N1E-115 cells was counted by Image J software. The fluorescence expression of recombinant ras homolog gene family member A (RhoA), rho associated coiledcoil protein kinase 2 (ROCK2), phospho-rho associated coiledcoil protein kinase 2 (p-ROCK2) and phospho-myosin light chain 2 (p-MLC2) proteins was detected by immunohistochemistry. Real-time fluorescent quantitative polymerase chain reaction was used to detect the mRNA expression levels of RhoA and ROCK2 ; the protein expression levels of RhoA, ROCK2, p-MLC2 and myosin light chain 2 (MLC2) were detected by Western blotting.Results:Compared with 20 μg/ml astragaloside Ⅳ group, the inhibition rate of neurite retraction in 40 and 80 μg/ml astragalosideⅣ groups increased ( P<0.05). Compared with model group, the average fluorescence intensity of RhoA, p-ROCK2, p-MLC2 in 20, 40, 80 μg/ml astragaloside Ⅳ groups and the ROCK2 average fluorescence intensity in 40 μg/ml astragaloside Ⅳ group were decreased ( P<0.05, P<0.01); the expression of RhoA mRNA (0.89±0.09, 0.41±0.01, 0.09±0.03 vs. 1.50±0.01) and ROCK2 mRNA (0.89±0.09, 0.14±0.01, 0.20±0.01 vs. 1.62±0.17) decreased in 20, 40, 80 μg/ml astragaloside Ⅳ groups ( P<0.05, P<0.01); the ROCK2 protein (0.75±0.06, 0.57±0.02, 0.66±0.01 vs. 1.08±0.02), p-MLC2 protein (1.72±0.03, 1.40±0.04, 1.29±0.03 vs. 2.19±0.11), MLC2 protein (1.13±0.02, 0.68±0.03, 0.75±0.03 vs. 1.60±0.03) in 20, 40, 80 μg/ml astragaloside Ⅳ groups and the RhoA protein (0.35±0.01, 0.40±0.03 vs. 0.57±0.08) in 20, 40 μg/ml astragaloside Ⅳ groups were decreased ( P<0.05, P<0.01). Conclusion:Astragaloside Ⅳ can prevent LPA-induced neurite retraction and promote damaged nerve regeneration. The mechanism may down-regulae the protein expression levels of RhoA, ROCK2, p-ROCK2, p-MLC2 and MLC2 in RhoA-ROCK2 signaling pathway, and inhibite nerve growth cone collapse.

ConclusionIcariin improves cognitive function and neuronal and dendritic damage in AD by inhibiting the RhoA/ROCK signaling pathway.

Effect of Achyranthis Bidentatae Radix-Paeoniae Radix Alba on Neuroinflammation and RhoA/ROCK2 Signaling Pathway in Parkinson's Disease Mouse Model / 中国实验方剂学杂志

ObjectiveTo investigate the protective effect and mechanism of Achyranthis Bidentatae Radix-Paeoniae Radix Alba on dopaminergic neurons in Parkinson's disease mouse model with the syndrome of ascendant hyperactivity of liver Yang. MethodThe C57BL/6 mice were randomly assigned into normal group， a model group， low-， medium， and high-dose （3.25， 6.5， 13 g·kg-1） Achyranthis Bidentatae Radix-Paeoniae Radix Alba groups， and a selegiline group （0.01 g·kg-1）. The mouse model of Parkinson's disease with the syndrome of ascendant hyperactivity of liver yang was established by intragastric administration of Fuzitang combined with intraperitoneal injection of 1-methyl-4-phenyl-1，2，3，6-tetrahydropyridine （MPTP）. The behavioral changes were evaluated by rotarod test and pole test. The protein levels of Ras homolog gene family member A （RhoA）， Rho-associated coiled-coil containing protein kinase 2 （ROCK2）， myosin light chain 1 （MLC1）， and α-synuclein in the substantia nigra were determined by Western blot. Real-time fluorescence quantitative PCR （Real-time PCR） was employed to determine the mRNA levels of RhoA， ROCK2， and MLC1 in the substantia nigra. Enzyme-linked immunosorbent assay （ELISA） was used to measure the levels of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β）. The ultrastructural changes of mouse neurons were observed under a transmission electron microscope. ResultCompared with the normal group， the modeling shortened the latency to fall， increased the average total time in the pole test （P<0.01）， and up-regulated the levels of RhoA， ROCK2， MLC1， TNF-α， α-synuclein， and IL-1β in the substantia nigra （P<0.05）. Compared with the model group， different doses of Achyranthis Bidentatae Radix-Paeoniae Radix Alba and selegiline prolonged the latency to fall， shortened the average total time in the pole test （P<0.05， P<0.01）， and down-regulated the levels of ROCK2， MLC1， α-synuclein， TNF-α， and IL-1β in a dose-dependent manner （P<0.05）. Further， the modeling decreased the number of cytoplasmic organelles and caused mitochondrial swelling and abnormal shape of endoplasmic reticulum compared with the normal group. The neurons in high-dose Achyranthis Bidentatae Radix-Paeoniae Radix Alba and selegiline groups showed intact nuclei， clear cell boundary， and normal endoplasmic reticulum shape. ConclusionThe combination of Achyranthis Bidentatae Radix and Paeoniae Radix Alba may improve the motor coordination ability of Parkinson's disease mouse model with the syndrome of ascendant hyperactivity of liver yang by inhibiting the neuroinflammation mediated by the RhoA/ROCK2 signaling pathway in the brain.
