ObjectiveTo systematically evaluate the efficacy and safety of Jiedu Tongluo therapy in the treatment of diabetic kidney disease （DKD）. MethodDatabases including CNKI， Wanfang Data， PubMed， and Web of Science were systematically searched from January 2003 to December 2022 for clinical randomized controlled trials （RCTs） on the application of Jiedu Tongluo therapy for DKD treatment over the past 20 years. In these trials， the control group received conventional treatment （including diabetes and kidney health education， glycemic and blood pressure control， and lifestyle interventions）， along with western medicine or Chinese patent medicine treatment. The experimental group received primarily Jiedu Tongluo therapy via oral administration of Chinese medicine or in combination with western medicine. The Cochrane risk of bias assessment tool was used for the quality evaluation of the trials， and R 4.1.0 statistical software was used for analysis. ResultForty-one RCTs with 3 478 participants were included. The Meta-analysis results demonstrated that the experimental group， compared with the control group， showed significant improvement in overall clinical efficacy ［odds ratio （OR）=2.46， 95% confidence interval （CI） （2.08， 2.92）， I2=0%］， effective reduction of serum creatinine （Scr） levels ［mean difference （MD）=-15.83， 95% CI （-21.5， -10.37）， P< 0.01］， 24-hour urinary protein excretion rate （24 h-Up） ［MD=-350.88， 95% CI （-419.49， -282.28）， P< 0.01］， TCM syndrome score ［MD=-6.08， 95% CI （-7.81， -4.36）， P<0.01］， and effective regulation of fasting blood glucose （FBG） ［MD=-0.57， 95% CI （-0.75， -0.38）， P<0.01］. The treatment also demonstrated certain safety ［OR=0.99， 95% CI （0.35， 2.76）］. ConclusionJiedu Tongluo therapy in DKD treatment exhibits favorable clinical efficacy and safety. However， due to limitations in the quality and quantity of the included literature， these conclusions should be further validated through larger-scale， high-quality RCTs.

Study on the mechanism of Yishen daluo decoction in alleviating nervous system inflammation in EAE model mice / 中国药房

OBJECTIVE To study the effects of Yishen daluo decoction on inflammatory factors and cyclic adenosine monophosphate（cAMP）/protein kinase A （PKA）/cAMP response element binding protein （CREB） signal pathway in experimental autoimmune encephalomyelitis （EAE） model mice by inhibiting the expressions of β-arrestin1， and to explore the mechanism of Yishen daluo decoction in the treatment of EAE. METHODS Sixty mice were randomly divided into normal group， model group， TCM group （Yishen daluo decoction 20 g/kg）， positive control group （prednisone acetate 3.9 mg/kg）， β-arrestin1 siRNA adeno- associated virus （AAV-β） group， AAV-β+TCM group， with 10 mice in each group. Except for normal group， EAE model was made in other groups. AAV-β group and AAV-β+TCM group were injected with AAV-β via tail vein to interfere with the expression of β -arrestin1 protein. Starting from the 8th day of modeling， they were given corresponding drug solution/normal saline intragastrically， once a day， for consecutive 14 days. The neurological function score of mice was detected； the pathological and morphological changes were observed in the brain and spinal cord tissues of mice； the serum levels of inflammatory factors [interleukin-2 （IL-2）， IL-23， interferon-γ （IFN-γ）] in mice were determined； the expressions of β-arrestin1， cAMP， PKA and CREB in brain and spinal cord were detected. RESULTS Compared with normal group， neurological function scores， serum levels of inflammatory factors， and protein expressions of β-arrestin1 in brain and spinal cord were significantly increased （P＜0.05 or P＜ 0.01）； protein expressions of PKA， CREB and cAMP in brain and spinal cord were decreased significantly（P＜0.05 or P＜0.01）. The deep staining of cellular shrinkage and aggregation of inflammatory cells were observed in most neurons of the brain and spinal cord， with varying degrees of demyelinating. Compared with model group， the neurological function scores， pathological changes in brain and spinal cord tissues， and most indicators （except for CREB and cAMP proteins in the brain tissue of AAV-β group） were significantly reversed （P＜0.05 or P＜0.01）.Compared with AAV- β group， the neurological function scores， the levels of IFN-γ in serum and β-arrestin1 in spinal cord were significantly decreased （P＜0.05 or P＜0.01）， PKA and cAMP in brain and spinal cord tissues were significantly increased in AAV- β +TCM group （P＜0.05 or P＜0.01）. CONCLUSIONS Yishen daluo decoction can inhibit the expression of β-arrestin1 in the central nervous system thus activating the cAMP/PKA/CREB signaling pathway， relieving nervous system inflammation， and ultimately alleviates the symptoms of EAE.

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.

DNA methylation in thyroid carcinoma / 临床耳鼻咽喉头颈外科杂志

Cancer has become clear that not merely gene variations but also epigenetic modifications may contribute to it. Epigenetic changes refer to stable alterations in gene expression with unrelated to changes in the underlying genetic sequence,resulting in heritable. DNA methylation is one of the common epigenetic changes. It control the gene expression through changing DNA conformation and stability, chromatin structer, DNA-protein interaction. The reversal of dysregulated DNA methylation has emerged as a potential strategy for the treatment of thyroid carcinoma. The artical will provide an overview of how DNA methylation contribute to thyroid carcinoma dissemination,invasion and metastasis and we will summarize the latest epigenetic therapies for thyroid carcinoma.

Semiquantitative analysis of the results of immunohistochemistry was conducted by image analysis software.@*RESULT@#(1) TFF3 protein was expressed in the cytoplasm of cancer cells,while TFF3 was negative or weakly positive in follicular cells of para-carcinoma tissue. The positive expression rate of TFF3 was 92.39%, of which the strong positive rate of clinical stage III-IV accounted for 71.79% (42/59) and that of clinical stage I-II was 33.33% (11/33) (P < 0.01). The positive rate of TFF3 was significantly higher in the cases with lymph node metastasis than those without lymph node metastasis (100.00% vs 86.27%, P < 0.05). The AOD value of TFF3 was higher in PTC than in para-carcinoma tissue, that in cases with lymph node metastasis was higher than those without lymph node metastasis, and that in stage III-IV was higher than those in I-II (P < 0.05 or P < 0.05). (2) There was high expression of SDF-1 in the cytoplasm of malignant tissues. The para-carcinoma tissue was weakly positive or negative to SDF 1 and metastatic lymph nodes was weakly positive to SDF 1. The positive rates and AOD values of SDF-1 protein were similar to those of TFF3 in PTC,that is to say the positive rate and AOD values were higher in PTC than in para-carcinoma tissue, those in cases with lymph node metastasis were higher than those without lymph node metastasis, those in stage III-IV were higher than those in I-II, and those in patients older than 45 years old was obviously higher than those in patients under 45 years old (P < 0.05 or P < 0.01); CXCR4 was also mainly expressed in cytoplasm with few expression in nuclei, while negative or weakly positive in para-carcinoma. The positive rate and AOD values of CXCR4 in PTC were similar to SDF-1, meaning that they were higher in PTC than in para-carcinoma tissue and associated with the clinical stage, lymph node metastasis and age (P < 0.05 or P < 0.01). (3) There was positive relationship between TFF3 and SDF-1 as well as between SDF-1 and CXCR4 in PTC (r = 0.971, P < 0.01).@*CONCLUSION@#The high expression of TFF3, SDF-1 and CXCR4 in PTC are correlated with carcinogenesis and progression, and may play a significant role in evaluating the malignancy degree and progression of PTC.
