Astragaloside IV inhibits Ang H-induced cell proliferation and collagen expression in cardiac fibroblasts by activating short-chain acyl-CoA dehydrogenase / 中国药理学通报

Aim To explore the effect of astragaloside IV (AS-IV) on cell proliferation and collagen expression in cardiac fibroblasts (CFs) of rats induced with angiotensin II (Ang II) and its mechanism. Methods CFs were pretreated with short-chain acyl-CoA dehydrogenase (SCAD) siRNA1186 for 12 h and then co-treated with Ang TJ and AS-IV for 36 h. The expressions of SCAD, α-SMA, collagen I and collagen III in CFs were detected by Western blot. mRNA expression levels of SCAD, a-SMA, collagen I and collagen III in CFs were detected by quantitative real-time PCR. The SCAD enzymatic activity, the content of ATP, hydroxyproline and free fatty acid were measured by detection kits. Results The expression of α-SMA, collagen I and collagen III were up-regulated (all P < 0. 01) in CFs induced by Ang II compared with the control cells, and the expression and enzymatic activity of SCAD significantly decreased (P < 0. 01, P< 0. 05). The content of ATP decreased (P < 0.01), and the content of hydroxyproline and free fatty acids increased (all P < 0.01). Compared with Ang II group, SCAD expression and enzymatic activity, and ATP content were significantly increased (all P < 0.01) in Ang II + AS-TV group, but the content of hydroxyproline and free fatty acids, and the expression of α-SMA, collagen I and collagen III significantly decreased (all P < 0.01). However, compared with the Ang II + NC group, there was no significant difference in all indices in the Ang II + SiRNA1186 + AS-TV group. The protective effect of AS-TV on Ang II -induced cell proliferation and collagen expression in CFs was eliminated by the interference of SCAD SiRNA1186. Conclusions AS-IV may inhibit Ang II-induced cell proliferation and collagen expression in CFs by activating SCAD.

Clinical and imaging features of acute encephalopathy with biphasic seizures and late reduced diffusion in children / 中华儿科杂志

Objective: To explore the clinical and imaging features of acute encephalopathy with biphasic seizures and late reduced diffusion(AESD) in children. Methods: For the case series study, 21 children with AESD from Peking University First Hospital, Provincial Children's Hospital Affiliated to Anhui Medical University, Children's Hospital of Fudan University, and Shanxi Children's Hospital who were diagnosed and treated from October 2021 to July 2023 were selected. Clinical data were collected to summarize their clinical information, imaging, and laboratory tests, as well as treatment and prognostic characteristics. Descriptive statistical analysis was applicated. Results: Of the 21 cases with AESD, 11 were males and 10 were females, with the age of onset of 2 years and 6 months (1 year and 7 months, 3 years and 6 months). Of the 21 cases, 18 were typical cases with biphasic seizures. All typical cases had early seizures within 24 hours before or after fever onset. Among them, 16 cases had generalized seizures, 2 cases had focal seizures, and 7 cases reached the status epilepticus. Of the 21 cases, 3 atypical cases had late seizures in biphasic only. The late seizures in the 21 cases occurred on days 3 to 9. The types of late seizures included focal seizures in 12 cases, generalized seizures in 6 cases, and both focal and generalized seizures in 3 cases. Diffusion-weighted imaging (DWI) test on days 3 to 11 showed reduced diffusion of subcortical white matter which was named "bright tree sign" in all cases. The diffuse cerebral atrophy predominantly presented in the front-parietal-temporal lobes was found in 19 cases between day 12 and 3 months after the onset of the disease. Among 21 cases, 20 had been misdiagnosed as autoimmune encephalitis, central nervous system infection, febrile convulsions, posterior reversible encephalopathy syndrome, acute disseminated encephalomyelitis, and hemiconvulsion-hemiplegia-epilepsy syndrome. All the cases received high-dose gammaglobulin and methylprednisolone pulse therapy with poor therapeutic effect. By July 2023, 18 cases were under follow-up. Among them, 17 cases were left with varying degrees of neurologic sequelae, including 11 cases with post-encephalopathic epilepsy; 1 recovered completely. Conclusions: AESD is characterized by biphasic seizures clinically and "bright tree sign" on DWI images. Symptomatic and supportive treatments are recommended. The immunotherapy is ineffective. The prognosis of AESD is poor, with a high incidence of neurological sequelae and a low mortality.

Neural Mechanism Underlying Task-Specific Enhancement of Motor Learning by Concurrent Transcranial Direct Current Stimulation / 神经科学通报·英文版

The optimal protocol for neuromodulation by transcranial direct current stimulation (tDCS) remains unclear. Using the rotarod paradigm, we found that mouse motor learning was enhanced by anodal tDCS (3.2 mA/cm2) during but not before or after the performance of a task. Dual-task experiments showed that motor learning enhancement was specific to the task accompanied by anodal tDCS. Studies using a mouse model of stroke induced by middle cerebral artery occlusion showed that concurrent anodal tDCS restored motor learning capability in a task-specific manner. Transcranial in vivo Ca2+ imaging further showed that anodal tDCS elevated and cathodal tDCS suppressed neuronal activity in the primary motor cortex (M1). Anodal tDCS specifically promoted the activity of task-related M1 neurons during task performance, suggesting that elevated Hebbian synaptic potentiation in task-activated circuits accounts for the motor learning enhancement. Thus, application of tDCS concurrent with the targeted behavioral dysfunction could be an effective approach to treating brain disorders.

OBJECTIVE@#To observe the short-term efficacy, long-term efficacy and safety of acupuncture for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).@*METHODS@#Forty-two patients with CP/CPPS were randomly divided into an acupuncture group (21 cases, 1 case dropped off) and a sham acupuncture group (21 cases). The patients in the acupuncture group were treated with acupuncture at bilateral Zhongliao (BL 33), Huiyang (BL 35), Shenshu (BL 23) and Sanyinjiao (SP 6); the needling depth of Zhongliao (BL 33) and Huiyang (BL 35) was 60 to 80 mm, while Shenshu (BL 23) and Sanyinjiao (SP 6) was directly punctured of 30 mm. The patients in the sham acupuncture group were treated with acupuncture at non-acupoints, including points 2 cm next to Shenshu (BL 23), Zhongliao (BL 33) and Huiyang (BL 35), and the midpoint of the connecting line between the spleen meridian and the kidney meridian. All the non-acupoints were treated with directly puncture of 2 to 3 mm. The needles were left for 30 min in both groups, once every other day in the first four weeks, three times a week, and twice a week in the next four weeks, totally 20 treatments. Before treatment, after treatment and in follow-up of 24 weeks after treatment completion, the National Institutes of Health-chronic prostatitis symptom index (NIH-CPSI) score and urinary flow rate were observed in both groups; the clinical efficacy and safety were evaluated.@*RESULTS@#Compared with those before treatment, the pain and discomfort scores, urination symptoms scores, quality of life scores and total scores of NIH-CPSI in both groups were reduced after treatment in the two groups (P<0.01), while each item score and total score of NIH-CPSI in the acupuncture group were reduced in follow-up (P<0.01, P<0.05). After treatment and in follow-up, each item score and total score of NIH-CPSI in the acupuncture group were lower than those in the sham acupuncture group (P<0.05, P<0.01). After treatment, the maximum and average urinary flow rates in the acupuncture group were higher than those before treatment (P<0.05), and the average urinary flow rate in the acupuncture group was higher than that in the sham acupuncture group (P<0.05). The total effective rate was 75.0% (15/20) in the acupuncture group, which was higher than 42.9% (9/21) in the sham acupuncture group (P<0.05). No significant adverse reactions were observed in the two groups, and there was no significant difference in the incidence of adverse reactions between the two groups (P>0.05).@*CONCLUSION@#Acupuncture could effectively alleviate the clinical symptoms, improve quality of life, and has a sustained, safe and reliable therapeutic effect in patients with CP/CPPS.

Exploring the effects of entecavir treatment on the degree of liver fibrosis in patients with non-alcoholic fatty liver combined with chronic hepatitis B in Tibet region / 中华肝脏病杂志

Objective: To explore the efficacy of entecavir antiviral therapy on the degree of liver fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) combined with chronic hepatitis B (CHB) in Tibet region. Methods: HBeAg-positive CHB patients who were treated with entecavir in the outpatient and inpatient Department of Infectious Diseases of the Tibet Autonomous Region people's Hospital between January 2018 to December 2019 were retrospectively analyzed. Among the 140 subjects with CHB, 95 cases were CHB alone, and the other 45 cases were diagnosed as CHB combined with NAFLD by ultrasound. All patients were given entecavir 0.5 mg orally once daily on an empty stomach for 48 weeks. HBeAg negative conversion rate, blood glucose, blood lipid, liver function and the degree of liver fibrosis were compared between the two groups at the 12th, 24th and 48th weeks of treatment to evaluate the virological response. SPSS 19.0 statistical software was used to process the data. Measurement data were expressed as mean ± standard deviation (x¯±s). Descriptive statistical analysis was used for t-test, and the categorical variables were expressed as percentage (%) and χ2 test. A p-value < 0.05 was considered as statistically significant. Results: After 48 weeks of treatment, the HBeAg and HBV DNA negative conversion rate were significantly better in patients with CHB alone (group B) than CHB combined with NAFLD (group A), that is to say, HBeAg negative conversion rate in group A and B patients were 28.90% and 40%, respectively, and group B was better than group A. HBV DNA negative conversion rate was significantly elevated in group B (83.2%) than group A (64.4%), with statistical significance (P<0.05), and the difference between the both groups was statistically significant. Alanine aminotransferase level was significantly decreased in patients with CHB alone than patients with CHB combined with NAFLD. Aspartate aminotransferase/platelet ratio index was significantly decreased after treatment than before treatment in both group of patients, and the depletion was more pronounced in CHB alone group. Liver stiffness values were significantly decreased in patients with CHB combined with NAFLD than CHB alone group. Moreover, liver stiffness values was higher in group A than group B before treatment under the influence of fat attenuation factors, and the differences before treatment and after treatment were 3.50±4.66 and 2.05±2.53, respectively; however, group B was not affected by fat attenuation factors, so LSM value reduction in group A was more obvious, and the differences were statistically significant. There was no statistically significant difference in blood glucose and blood lipids levels before and after treatment between the two groups. Conclusion: NAFLD has a certain effect on antiviral therapy and liver fibrosis in patients with CHB, i.e., the effect of antiviral therapy in patients with CHB alone is better than patients with CHB combined with NAFLD. Patients with CHB combined with NAFLD when treated with antiviral therapy had a significantly greater degree of liver stiffness reduction than patients with CHB alone. Therefore, it is necessary to actively intervene the risk factors associated with NAFLD according to the actual situation of different individuals to improve clinical efficacy of antiviral therapy.

The Levels of Inflammatory Regulatory Factors in Acute Leukemia Complicated by Infection and Its Clinical Significance / 中国实验血液学杂志

OBJECTIVE@#To explore the expression levels and clinical significance of helper T cell 1/helper T cell 2 (Th1/Th2) cytokine and interleukin-6 (IL-6) in patients with acute leukemia (AL) complicated by infection.@*METHODS@#68 patients with AL complicated by infection admitted to Wuhan Fifth Hospital from May 2017 to January 2020 were enrolled as study group, 50 AL patients without infection were enrolled as AL group, and 30 healthy volunteers checked in physical examination center were enrolled as healthy control group. The levels of serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-10 (IL-10), and peripheral blood Th1/Th2 cells subsets were measured and compared among the three groups. The serum IL-6, IL-10, TNF-α and Th1/Th2 were compared between the patients with mild to moderate infection (n=52) and septic shock (n=16). The relationship between IL-6, IL-10, TNF-α, Th1/Th2 and AL infection was analyzed.@*RESULTS@#The levels of IL-6, IL-10 , TNF-α, and the proportion of Th2 of the patients in study group and AL group were significantly higher than those in healthy control group (P<0.001), while the proportion of Th1 and Th1/Th2 were significantly lower than those in healthy control group (P<0.001). The levels of IL-6, IL-10 and TNF-α, and the proportion of Th2 the patients in study group were significantly higher than those in AL group (P<0.001), while the proportion of Th1 and Th1/Th2 were significantly lower than those in AL group (P<0.001). The serum IL-6, IL-10 and TNF-α level of the patients in septic shock group were significantly higher than those in mild-to-moderate infection group (P<0.001), while Th1/Th2 was lower than those in mild-to-moderate infection group (P<0.001). The results of ROC curve analysis showed that the area under the ROC curve (AUC) values of IL-6, IL-10, TNF-α and Th1/Th2 alone for the diagnosis of septic shock were 0.779, 0.761, 0.724 and 0.718, which were lower than that their combination (0.910) (P<0.05).@*CONCLUSION@#The levels of serum IL-6, IL-10 and TNF-α are high in patients with AL complicated infection and septic shock, while Th1/Th2 cell subsets is low. The combined detection of serum IL-6, IL-10, TNF-α and Th1/Th2 is a good diagnostic value for predicting the occurrence of severe septic shock.

Joint association of sedentary behavior and physical activity on anxiety tendency among occupational population in China / 北京大学学报(医学版)

OBJECTIVE@#To investigate the status and influencing factors of anxiety tendency among occupational population in China and to examine the joint association between sedentary behavior and physical activity with anxiety tendency.@*METHODS@#The data were from the 2021 Asia Best Workplace (Chinese mainland) program. The Generalized Anxiety Tendency scale was used to assess employees' anxiety status, and Logistic regression was used to analyze the factors influencing anxiety tendency and calculate the odds ratio (OR) within different groups. The OR of sitting for each sitting-physical activity (PA) combination group and within PA strata were calculated to explore the joint association.@*RESULTS@#A total of 11 903 workers with an average age of 32.9 years were included in this study. Among them, 3 562 workers had anxiety tendency (29.9%) and the prevalence of those under 40 years old (30.6%) was significantly higher than the other age group (26.7%). 41.0% of the respondents had the moderated to vigorous physical activity. Their average daily sitting time was 9.4 h, and the percentage of those who exceeded 8 h sitting reached 73.9% in the past week. The analysis of Logistic regression showed that smoking (OR=1.24, 95%CI: 1.23-1.39), longer sedentary time and lower physical activity level were risk factors for anxiety tendency, and longer average daily sleep time (OR=0.56, 95%CI: 0.51-0.61) was a protective factor. The joint association analysis and stratified analysis of physical activity and sedentary behavior with anxiety tendency showed that increased sedentary time combined with decreased physical activity intensity was significantly associated with increased risk of anxiety tendency (range of OR: 1.64-3.14). The threshold for sedentary time in total as a risk factor for anxiety tendency gradually decreased as physical activity intensity increased.@*CONCLUSION@#The anxiety tendency and sedentary behavior among the occupational population should recieve more attention. Lack of physical activity and sedentary behavior are both risk factors for anxiety tendency, and strengthening the intensity of physical activity can attenuate the harmful effects of sedentary behavior on anxiety tendency.

Recent progress in the diagnosis of vitreoretinal lymphoma / 国际眼科杂志(Guoji Yanke Zazhi)

Vitreoretinal lymphoma(VRL)is a rare and aggressive non-Hodgkin's lymphoma, and its early and correct diagnosis is still a great challenge because of its non-specific clinical presentation. For VRL diagnosis, pathological cytology is still the gold standard, but its diagnosis needs to combine with clinical manifestations, imaging features, immunological and molecular technology and so on. With the advancement of diagnostic technology, more efficient techniques of cytology and assistant diagnosis have been explored. Cytokines and interleukin score for intraocular lymphoma diagnosis(ISOLD), myeloid differentiation gene 88(MYD88)mutation and next-generation sequencing have higher diagnostic accuracy, so they have gradually become important auxiliary diagnostic methods and research hotspots.

YANG Jun's clinical experience of acupuncture for oculomotor paralysis / 中国针灸

Professor YANG Jun's clinical experience of acupuncture and moxibustion for oculomotor paralysis is summarized. Professor YANG Jun pays attention to disease differentiation and syndrome differentiation in the treatment of this disease. According to the characteristics of oculomotor paralysis, "early diagnosis and seeking treatment from the source" is advocated. According to the etiology and pathogenesis, professor YANG divides oculomotor paralysis into three types: the syndrome of wind-evil attacking collaterals, the syndrome of spleen-stomach weakness and the syndrome of qi-deficiency and blood-stasis. As such, the acupoints are selected according to syndrome differentiation, and several different acupuncture methods (pricking needling at eyelids, penetrating needling and lifting eyelids and contralateral- balance needling on the healthy side) are adopted to improve the symptoms of oculomotor paralysis. It is also suggested to use the combination of scalp acupuncture and electroacupuncture to achieve the best dose-effect state. Moreover, local stimulation around the eyes is important to achieve the effects of "qi reaching affected area".

Impact of health literacy on patient experience of outpatients in China and its mechanism / 北京大学学报(医学版)

OBJECTIVE@#To understand the relationship between health literacy and patient experience of outpatients in China, and to explore its mechanism.@*METHODS@#The conceptual framework was developed based on Andersen's behavioral model of health services use and health literacy skills framework. An online cross-sectional survey was conducted with snowball sampling method, while the health literacy was measured by self-designed patient health literacy scale, and the patient experience was measured by the Chinese patient experience questionnaire for ambulatory care developed by Peking Union Medical College. And a structural equation model was built to explore the relationship between them and test the mechanism of health literacy influencing patient experience.@*RESULTS@#A total of 2 773 subjects were investigated. The average score of health literacy was (90.72±12.90) points, accounting for 78.89% of the full score, and the dimension of seeking social support had the lowest score. The average score of overall rating of patient experience was (3.71±0.74) points, and the scores of each dimension of patient experience were between 3.56 and 3.80. The model fit indices of structural equation model for overall rating of patient experience among the outpatients were χ2/df=9.29 (χ2=4 107.27, df=442), root mean square error of approximation (RMSEA)=0.055 (< 0.06), comparative fit index (CFI)=0.926 (>0.90), Tucker-Lewis index (TLI)=0.918 (>0.90), standardized root mean square residual (SRMR)=0.061 (< 0.08), the model was acceptable. The variance in patient experience explained by the model was 0.108. The structural equation model analysis results showed that the overall rating of outpatient experience was directly affected by health literacy (β=0.263, P < 0.001), also indirectly affected by health literacy (β=0.012, P < 0.001). In other words, the overall rating increased by 0.275 units for each standard deviation increase of health literacy. Self-evaluated health status mediated the relationship between health literacy and the overall rating of outpatient experience. In terms of diffe-rent dimensions of patient experience, the standardized path coefficient of the total effect of health literacy on patient experience was as follows: Information guidance 0.337, humanistic care 0.319, communication with doctors 0.294, service efficiency 0.240, and hospital environment 0.173.@*CONCLUSION@#The patients with higher level of health literacy were more likely to have a better outpatient experience in China, and the information guidance experience and humanistic care experience were most affected by health literacy. And the communication and information utilization ability had the greatest influence on patient experience.

Association between sleep quality and risk of acute exacerbation of mild and moderate chronic obstructive pulmonary disease： a community-based prospective study / 上海预防医学

Objective:To investigate the association between sleep quality and the risk of acute exacerbation in mild and moderate chronic obstructive pulmonary disease （COPD） patients in Pudong New Area of Shanghai. Methods:This was a prospective study involving eligible mild and moderate COPD patients from 10 communities randomly selected in Pudong New District of Shanghai. A structured questionnaire was used to collect demographic characteristics， clinical information and information on acute exacerbation. Sleep quality was assessed using the Pittsburgh Sleep Quality Index （PSQI） in Chinese. Multiple negative binomial regression was used to estimate the association between sleep quality and risk of exacerbation. Results:Altogether 212 mild/moderate COPD patients participated and completed the entire survey， of whom the majority （95.8%） were mild COPD patients， 110 persons female and over half （54.2%） over 65 years old. 32.9% of the patients had poorer sleep quality at baseline. 18.9% of the patients reported exacerbation over the past year during follow-ups. Multiple negative binomial regression suggested that increased PSQI was related to higher risk of exacerbation （RRad=1.12， 95%CI：1.02-1.24）， and patients with poorer sleep efficiency had a higher risk of exacerbation （RRad=1.66， 95%CI：1.17-5.43）. Conclusion:Poorer sleep quality is associated with a higher risk of exacerbation in community mild/moderate COPD patients， especially in those with problem of sleep efficiency. More attention to sleep disorders is warranted in community management or self-management of patients with COPD.

Therapeutic effects of artesunate on cytomegalovirus pneumonia in mice / 药学学报

To investigate the therapeutic effect of artesunate on mouse cytomegalovirus pneumonia, the BALB/c-nu mice were infected with murine cytomegalovirus-green fluorescent protein (MCMV-GFP) by nose dropping method. The experimental protocol was approved by the Medical Laboratory Animal Ethics Committee of Guangzhou Medical University. The BALB/c-nu mice were randomly divided into five groups: control group, MCMV pneumonia group, and artesunate (60, 120, and 240 mg·kg-1) groups. The survival rate, weights, and virus loads in lungs among the groups were observed. The degree of histopathologic changes in lungs was assessed directly by hematoxylin-eosin (HE) assay. MCMV-GFP expression was assessed by immunofluorescence. In addition, reverse transcription polymerase chain reaction (RT-PCR) analysis was performed to investigate the content of major immediate early 1 (Mie1) mRNA, and enzyme-linked immunosorbent assay (ELISA) was used to detect the changes of inflammatory factors, interleukin 10 (IL-10), IL-6, and tumor necrosis factor-α (TNF-α). Western blot analysis was used to detect the expression of the changes of nuclear factor-kappa B (NF-κB) signaling pathways in total proteins. Compared with MCMV group, artesunate (120 mg·kg-1) significantly increased body weights of MCMV-infected nude mice over 30 days, and decreased the viral titer in lung homogenate, lung inflammation, and histological severity. Moreover, the administration of artesunate (120 mg·kg-1) could downregulate the expression of phospho-NF-κB (p-NF-κB) p65 in the lungs of mice. The present study suggested that artesunate can protect the immunocompromised mice from MCMV-induced interstitial pneumonia via downregulating NF-κB signaling pathway, thus attenuating inflammation in the lungs.

Ultrasound for diagnosing new difficult laryngoscopy indicator: a prospective, self-controlled, assessor blinded, observational study / 中华医学杂志(英文版)

BACKGROUND@#Unpredictable difficult laryngoscopy (DL) remains a challenge for anesthesiologists, especially when difficult ventilation occurs during standard laryngoscopy. Accurate airway assessment should always be performed, but the common airway assessment methods only perform superficial screening. Thus, the deep laryngopharyngeal anatomy may not be evaluated. Ultrasound-based airway assessment has been recently proposed as a useful, simple, and non-invasive bedside tool as an adjunct to clinical methods, which may facilitate identification of DL. The present study aimed to determine the correlation between ultrasound-measured indicators and DL.@*METHODS@#Patients undergoing elective surgery under general anesthesia with tracheal intubation were enrolled. Ultrasonic airway assessments were performed before anesthesia induction. Ultrasound diagnostic indicators included the thickness and width of the base of the tongue, the angle between the epiglottis and glottis, the length of the thyrohyoid membrane, and the thickness of the lateral pharyngeal wall. A score of ≥3 in the Modified Cormack-Lehane Scoring System was used as a standard of DL and was also applied to divide patients into DL and non-DL groups. The area under the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic ability of various diagnostic indicators.@*RESULTS@#A total of 499 patients were enrolled into non-DL and DL groups comprising 452 (452/499, 90.6%) and 47 (47/499, 9.4%) patients, respectively. One ultrasonic diagnoses indicator correlated with DL, namely, the angle between the epiglottis and glottis. When the angle between the epiglottis and glottis was 50°, the area under the ROC curve was maximum (0.902), and the best sensitivity (81%) and specificity (89%) were achieved.@*CONCLUSIONS@#Airway ultrasounds should be considered to identify DL.

Protective Effects and Mechanisms of Shenhua Tablet () on Toll-Like Receptors in Rat Model of Renal Ischemia-Reperfusion Injury / 中国结合医学杂志

OBJECTIVES@#To investigate the protective effects and potential mechanisms of Shenhua Tablet (, SHT) on the toll-like receptors (TLRs)-mediated signaling pathways in a rat model of kidney ischemia-reperfusion injury (IRI).@*METHODS@#Sixty male Wistar rats were randomly divided into 5 groups: sham surgery, model control, astragaloside (150 mg•kg•d), low- and high-dose SHT (1.5 and 3.0 g•kg•d, repectively) groups. One week after drug treatment, rats underwent surgery to establish the IRI models. At 24 h and 72 h after the modeling, serum creatinine (Scr) and blood urea nitrogen (BUN) were analyzed; pathological damage were scored after periodic acid-Schiffstaining. TLR2, TLR4 and myeloid differentiation factor 88 (MyD88) protein and mRNA expressions were detected by inmmunohistochemistry, Western blot and qPCR. Tumor necrosis factor α (TNF-α) and interleukin-6 (IL-6) protein expressions were detected by enzyme linked immunosorbent assay.@*RESULTS@#Compared with the sham group, the model group exhibited severe change in renal function (Scr: 189.42±21.50, P<0.05), pathological damage (damage score: 4.50±0.55, P<0.05), and the expression levels of TLR2, TLR4, MyD88, TNF-α, IL-6 were significantly higher than other groups. Meanwhile, the levels of TLRs in model group showed upward tendency from 24 to 72 h, unparalleled with pathological and functional changes. The aforementioned parameters were alleviated to a certain extent, and, in addition to TLRs, presented the obvious downward trending from the 24 to 72 h after the intervention in the SHT and astragaloside groups relative to the model (P<0.05); in particular, the most significant mitigation of these changes was observed in the SHT-H group (P<0.05).@*CONCLUSION@#TLRs may be an important spot to treat and research in acute kidney injury. SHT could effectively mitigate renal injuries and promote recovery of IRI injuries through suppression of degeneration induced by up-regulation of TLR2 and TLR4 expression levels in the MyD88-dependent signaling pathway and exhibit some dose dependence.
