Exploration of Role of Yin and Yang Syndrome Differentiation in Parkinson's Disease / 中国实验方剂学杂志

The syndrome differentiation of Yin and Yang has the function of controlling the other six principles in the eight principles syndrome differentiation，which is a higher level or general induction of the disease. In the clinical process of traditional Chinese medicine，syndrome differentiation of Yin and Yang runs through the whole process of disease diagnosis and treatment. For Parkinson's disease，syndrome differentiation of Yin and Yang is particularly important. Different symptoms，the transformation of pathogenesis during the development of the disease and the treatment of traditional Chinese and western medicine all reflect the characteristics of Yin and Yang opposition restriction，mutual root and mutual use，and the transformation of ebb and flow. This article discusses the background，application and value of Yin-Yang syndrome differentiation from three aspects：the origin and application of yin-yang syndrome differentiation，the basis of Parkinson's disease syndrome differentiation，and the status and role of Yin-Yang syndrome differentiation in Parkinson's disease. It is of great significance to guide the diagnosis and treatment of Parkinson's disease with "Yin-Yang as the key point".

Phacoemulsification combined with capsular tension ring and intraocular lens implantation in the treatment of high myopia with cataract / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To observe the efficacy of phacoemulsification combined with capsular tension ring and intraocular lens implantation in the treatment of high myopia with cataract.METHODS: Retrospective study. A total of 82 cases(82 eyes)of high myopia complicated with cataract who admitted to the cataract department of our hospital from December 2021 to April 2023 were selected as study objects, and they were divided into control group(n=39)and combination group(n=43)according to whether or not the capsular tension ring was used intraoperatively. Patients in the control group were treated with intraocular lens implantation alone, and those in the combination group were treated with phacoemulsification combined with capsular tension ring and intraocular lens implantation. The preoperative and postoperative best corrected visual acuity, central anterior chamber depth, trabecular ciliary process, visual quality and complications were compared.RESULTS: At 1 mo after surgery, the best corrected visual acuity(LogMAR)of both groups increased significantly(combination group: 0.64±0.28 vs 0.12±0.14; control group: 0.62±0.26 vs 0.23±0.25, both P<0.001). Central anterior chamber depth in both groups were higher than those before surgery(combination group: 2.57±0.56 vs 1.97±0.40 mm; control group: 2.22±0.45 vs 1.89±0.37 mm; both P<0.001), and the best corrected visual acuity and central anterior chamber depth of the combination group were significantly better than those of the control group(both P<0.05). The distance of trabecular ciliary process showed no statistical significance(combination group: 0.68±0.22 vs 0.74±0.20 mm; control group: 0.74±0.19 vs 0.78±0.17 mm, both P>0.05). The visual quality scores of the combination group were all higher than the control group at 1 mo after surgery [watching TV: 3.00±0.38 vs 2.22±0.46 points; reading books: 2.85±0.42 vs 2.21±0.44 points; night vision: 2.71±0.34 vs 2.37±0.41 points; fine operation: 2.82±0.38 vs 2.33±0.40 points, all P<0.001]. The incidence of complication in the combination group was significantly lower than that of the control group(33% vs 14%, P<0.05).CONCLUSION: Phacoemulsification combined with capsular tension ring and intraocular lens implantation can effectively promote the recovery of visual function, improve the structure of chamber angle, and reduce the incidence of complications in the treatment of patients with high myopia and cataract.

The effect of LeCompte maneuver on mid-to-long term reintervention after arterial switch operation in children with side-by-side Taussig-Bing anomaly / 中国胸心血管外科临床杂志

@#Objective    To explore the effect of LeCompte maneuver on in-hospital mortality and mid-to-long term reintervention after single-stage arterial switch operation in children with side-by-side Taussig-Bing anomaly. Methods     Clinical data of patients diagnosed with side-by-side Taussig-Bing anomaly and undergoing single-stage arterial switch operation in Shanghai Children’s Medical Center from 2006 to 2017 were retrospectively analyzed. Patients were divided into two groups based on whether LeCompte maneuver was performed: a LeCompte maneuver group and a non LeCompte maneuver group. The clinical data of two groups were compared. Results    Finally 92 patients were collected. LeCompte maneuver was performed in 32 out of 92 patients with a median age of 65.0 days and an average weight of 4.3 kg, among whom 24 (75.0%) were male. Fifteen (46.9%) patients received concomitant aortic arch repair while 12 (37.5%) patients were associated with coronary artery malformation. LeCompte maneuver was not performed in 60 patients with a median age of 81.0 days and an average weight of 4.8 kg, among whom 45 (75.0%) were male. Twenty-two (36.7%) patients received concomitant aortic arch repair while 35 (58.3%) patients were associated with coronary artery malformation. The average cardiopulmonary bypass duration of the LeCompte maneuver group showed no statistical difference from the non LeCompte maneuver group (179.0±60.0 min vs. 203.0±74.0 min, P=0.093). The in-hospital mortality of the two groups were 6 (18.8%) and 7 (11.7%), respectively, which also showed no statistical difference (P=0.364). The median follow-up period was 4.1 (1.6, 7.5) years for 79 patients with 8 lost to follow-up, and no death was observed. Kaplan-Meier curve and log-rank test showed no statistical difference in overall mid-to-long term reintervention rate (P=0.850) as well as right ventricular outflow tract and pulmonary artery reintervention rate (P=0.240) with or without LeCompte maneuver. Conclusion    Whether or not to perform LeCompte maneuver shows no statistical impact on in-hospital mortality and mid-to-long term reintervention rate of single-stage arterial switch operation for side-by-side Taussig-Bing anomaly.

Non-targeted LC-MS profiling reveals association between human early embryo grades and levels of amino acids and carnitines in embryo culture medium / 中华检验医学杂志

Objective:In order to determine the development potential of human embryos in vitro, amino acid and carnitine levels were measured in the culture medium of different grades of early human embryos. Methods:From the infertile couples who received in vitro fertilization-embryo transfer treatment in the Department of Reproductive Medicine of Linyi People′s Hospital from June 2022 to December 2022, the age of the women was defined as 25-35 years old [31.5(26.5, 33.25)] with 8-20 eggs, 126 cultured cells and embryos of the third day were randomly collected from infertile couples. They were divided into three groups according to the morphological level of the corresponding embryos: excellent, neutral and poor. Amino acids and L-carnitines levels in culture medium were detected by liquid chromatography-mass spectrometry (LC-MS). Using analysis of variance to compare differences among groups, correlation analysis, factor analysis was performed to analyze the association between the levels of amino acids and L-carnitines and development potential of early human embryos.Results:The value of Methionine/Phenylalanine was found statistically different among superior embryo (3.09±1.67), moderate embryo (4.00±1.19) and inferior embryo (4.99±2.04). The difference between the three groups was statistically different ( F=7.09, P<0.05): superior embryo vs moderate embryo ( t=-0.91, P<0.05), superior embryo vs inferior embryo ( t=-1.91, P<0.05), moderate embryo vs inferior embryo ( t=-0.99, P<0.05). Among different amino acids, Phe had the strongest positive correlation with Tyr ( r=0.99, P<0.01). Among different carnitines, C 8/C 10 has the strongest positive correlation with C 5DC+C 6OH/C 16( r=0.44, P<0.01). The weight value of leucine (isoleucine), arginine, valine/phenylalanine, glycine, tyrosine and carnitine(C 5DC+C 6OH)/C 8 calculated by the least square fitting model is 2.22, 1.99, 1.65, 1.54, 1.21 and 1.15 respectively. Conclusion:Leucine, arginine, valine/phenylalanine, glycine, tyrosine and carnitine (C 5DC+C 6OH)/C 8 in embryo culture medium were significantly correlated with the levels of early human embryos in vitro.

Comparison of frailty assessment and related tools in elderly hospitalized patients with atrial fibrillation / 中华老年医学杂志

Objective:We evaluated frailty in elderly hospitalized patients with atrial fibrillation and analyzed the relevance, consistency, and diagnostic power of different frailty tools.Methods:From September 2018 to April 2019, a total of 197 elderly patients with atrial fibrillation aged ≥ 65 years in Beijing Hospital, Chinese PLA General Hospital, and Beijing Tsinghua Changgung Hospital were prospectively enrolled.Five frailty tools, including the clinical frailty scale(CFS), FRAIL scale(FRAIL), Fried frailty phenotype(Fried), Edmonton frail scale(EFS), and comprehensive geriatric assessment-frailty index(CGA-FI), were used for frailty assessment.Results:A total of 197 hospitalized elderly patients with atrial fibrillation were enrolled, with an average age of(77.5±7.1)years old(57.4% male). The prevalence of frailty, according to the five frailty tools, were 25.4%(FRAIL), 27.9%(EFS), 34.5%(Fried), 40.6%(CFS), and 42.6%(CGA-FI), respectively.CFS had a good correlation(correlation coefficient 0.80)and and consistency(Kappa value 0.71, 95% CI 0.61~0.81)with CGA-FI.The combined frailty index was used as the gold standard for frailty diagnosis.The results showed that CFS and CGA-FI had high diagnostic sensitivity(95.9 % and 98.0 %, respectively)and specificity(77.7 % and 75.7 %, respectively). Conclusions:Frailty is common in elderly hospitalized patients with atrial fibrillation, showing multidimensional features, and physical weakness is not prominet.CFS and CGA-FI are recommended for the assessment of frailty in patients with atrial fibrillation, which had good correlation and consistency.

Differential diagnosis and surgical management in chondrosarcoma of the jugular foramen / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the diagnosis, surgical management and outcome of jugular foramen chondrosarcoma (CSA). Methods: Fifteen patients with jugular foramen CSA hospitalized in the Department of Otorhinolaryngology Head and Neck Surgery of Chinese PLA General Hospital from December 2002 to February 2020 were retrospectively collected,of whom 2 were male and 13 were female, aging from 22 to 61 years old. The clinical symptoms and signs, imaging features, differential diagnosis, surgical approaches, function of facial nerve and cranial nerves IX to XII, and surgical outcomes were analyzed. Results: Patients with jugular foramen CSA mainly presented with facial paralysis, hearing loss, hoarseness, cough, tinnitus and local mass. Computed tomography (CT) and magnetic resonance (MR) could provide important information for diagnosis. CT showed irregular destruction on bone margin of the jugular foramen. MR demonstrated iso or hypointense on T1WI, hyperintense on T2WI and heterogeneous contrast-enhancement. Surgical approaches were chosen upon the sizes and scopes of the tumors. Inferior temporal fossa A approach was adopted in 12 cases, inferior temporal fossa B approach in 2 cases and mastoid combined parotid approach in 1 case. Five patients with facial nerve involved received great auricular nerve graft. The House Brackmann (H-B) grading scale was used to evaluate the facial nerve function. Preoperative facial nerve function ranked grade Ⅴ in 4 cases and grade Ⅵ in 1 case. Postoperative facial nerve function improved to grade Ⅲ in 2 cases and grade Ⅵ in 3 cases. Five patients presented with cranial nerves Ⅸ and Ⅹ palsies. Hoarseness and cough of 2 cases improved after operation, while the other 3 cases did not. All the patients were diagnosed CSA by histopathology and immunohistochemistry, with immunohistochemical staining showing vimentin and S-100 positive, but cytokeratin negative in tumor cells. All patients survived during 28 to 234 months' follow-up. Two patients suffered from tumor recurrence 7 years after surgery and received revision surgery. No complications such as cerebrospinal fluid leakage and intracranial infection occurred after operation. Conclusions: Jugular foramen CSA lacks characteristic symptoms or signs. Imaging is helpful to differential diagnosis. Surgery is the primary treatment of jugular foramen CSA. Patients with facial paralysis should receive surgery in time as to restore the facial nerve. Long-term follow-up is necessary after surgery in case of recurrence.

Emodin Ameliorates High Glucose-Induced Podocyte Apoptosis via Regulating AMPK/mTOR-Mediated Autophagy Signaling Pathway / 中国结合医学杂志

OBJECTIVE@#To investigate the effect of emodin on high glucose (HG)-induced podocyte apoptosis and whether the potential anti-apoptotic mechanism of emodin is related to induction of adenosine-monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR)-mediated autophagy in podocytes (MPC5 cells) in vitro.@*METHODS@#MPC5 cells were treated with different concentrations of HG (2.5, 5, 10, 20, 40, 80 and 160 mmol/L), emodin (2, 4, 8 µ mol/L), or HG (40 mmol/L) and emodin (4 µ mol/L) with or without rapamycin (Rap, 100 nmol/L) and compound C (10 µ mol/L). The viability and apoptosis of MPC5 cells were detected using cell counting kit-8 (CCK-8) assay and flow cytometry analysis, respectively. The expression levels of cleaved caspase-3, autophagy marker light chain 3 (LC3) I/II, and AMPK/mTOR signaling pathway-related proteins were determined by Western blot. The changes of morphology and RFP-LC3 fluorescence were observed under microscopy.@*RESULTS@#HG at 20, 40, 80 and 160 mmol/L dose-dependently induced cell apoptosis in MPC5 cells, whereas emodin (4 µ mol/L) significantly ameliorated HG-induced cell apoptosis and caspase-3 cleavage (P<0.01). Emodin (4 µ mol/L) significantly increased LC3-II protein expression levels and induced RFP-LC3-containing punctate structures in MPC5 cells (P<0.01). Furthermore, the protective effects of emodin were mimicked by rapamycin (100 nmol/L). Moreover, emodin increased the phosphorylation of AMPK and suppressed the phosphorylation of mTOR. The AMPK inhibitor compound C (10 µ mol/L) reversed emodin-induced autophagy activation.@*CONCLUSION@#Emodin ameliorated HG-induced apoptosis of MPC5 cells in vitro that involved induction of autophagy through the AMPK/mTOR signaling pathway, which might provide a potential therapeutic option for diabetic nephropathy.

Research progress of Eubacterium and its metabolite short-chain fatty acids in regulating type 2 diabetes mellitus / 中华预防医学杂志

Intestinal flora and its metabolites are closely related to the progression of type 2 diabetes mellitus(T2DM). Eubacterium is one of the dominant intestinal flora, and its metabolites short-chain fatty acids (SCFAs) play a leading role in regulating intestinal metabolic balance. It has been reported that SCFAs can regulate the secretion of glucagon-like peptide-1, improve the function of pancreatic β cells, participate in bile acids metabolism and regulate the production of inflammatory factors in T2DM. Based on the above research background, this article mainly reviews the relationship between Eubacterium and its metabolite SCFAs and T2DM and its regulatory mechanism.

The Physiological Functions and Polymorphisms of Type II Deiodinase

Type II deiodinase (DIO2) is thought to provide triiodothyronine (T3) to the nucleus to meet intracellular needs by deiodinating the prohormone thyroxine. DIO2 is expressed widely in many tissues and plays an important role in a variety of physiological processes, such as controlling T3 content in developing tissues (e.g., bone, muscles, and skin) and the adult brain, and regulating adaptive thermogenesis in brown adipose tissue (BAT). However, the identification and cloning of DIO2 have been challenging. In recent years, several clinical investigations have focused on the Thr92Ala polymorphism, which is closely correlated with clinical syndromes such as type 2 diabetes, obesity, hypertension, and osteoarthritis. Thr92Ala-DIO2 was also found to be related to bone and neurodegenerative diseases and tumors. However, relatively few reviews have synthesized research on individual deiodinases, especially DIO2, in the past 5 years. This review summarizes current knowledge regarding the physiological functions of DIO2 in thyroid hormone signaling and adaptive thermogenesis in BAT and the brain, as well as the associations between Thr92Ala-DIO2 and bone and neurodegenerative diseases and tumors. This discussion is expected to provide insights into the physiological functions of DIO2 and the clinical syndromes associated with Thr92Ala-DIO2.

Mechanism of Modified Danggui Shaoyao San in treatment of chronic atrophic gastritis based on network pharmacology and experimental verification / 中国药理学通报

Aim To predict the targets of Modified Danggui Shaoyao San ( MDSS) in the treatment of chronic atrophic gastritis ( CAG) based on network pharmacology and vertify the results based on experim-ention. Methods TCMSP, SWISS TARGETS, GENE CARDS and OMIM databases were used to screen the therapeutic targets of MDSS for CAG. STRING database and Cytoscape software were used to construct the protein interaction network and screen the core targets. Metascape database was used for GO analysis and KEGG enrichment pathways. And molecular docking was used for target validation. CAG rat model was pre¬pared by N-methyl-N'-nitroso-N-nitroguanidine free drink combined with sodium salicylate gastric lavage. The pathology of rat gastric mucosa was observed by hematoxylin-eosin staining,and the ultrastructure of ep¬ithelial cells was observed by transmission electron mi-croscopy. The serum IL-6 and IL-10 content was detected by enzyme-linked immunosorbent assay, and the expression of JAK2, STAT3 , p-STAT3 , c-MYC mRNA and protein in rats was detected by qPCR and Western blot. Results MDSS acted on 189 targets, mainly involved in response to oxidative stress and apoptotic signaling pathway. KEGG analysis related to pathways in cancer and JAK-STAT signaling pathway. The experimental results showed that the MDSS could improve the degree of atrophy of gastric mucosa in CAG rats and improve the status of epithelial cells, down-regulate the serum IL-6 content of CAG rats, up-regulate the IL-10 content, and reduce the expression of JAK2, STAT3 , p-STAT3 , c-MYC mRNA and protein in gastric mucosa with statistical significance. Conclusions MDSS treats CAG through multiple active ingredients, targets, and pathways, the mechanism of which may be related to the inhibition of the JAK2/STAT3 signaling pathway.

Momordicine I alleviates isoproterenol-induced cardiomyocyte hypertrophy through suppression of PLA2G6 and DGK-ζ

This study aimed to observe the protective effect of momordicine I, a triterpenoid compound extracted from momordica charantia L., on isoproterenol (ISO)-induced hypertrophy in rat H9c2 cardiomyocytes and investigate its potential mechanism. Treatment with 10 μM ISO induced cardiomyocyte hypertrophy as evidenced by increased cell surface area and protein content as well as pronounced upregulation of fetal genes including atrial natriuretic peptide, β-myosin heavy chain, and α-skeletal actin; however, those responses were markedly attenuated by treatment with 12.5 μg/ml momordicine I. Transcriptome experiment results showed that there were 381 and 447 differentially expressed genes expressed in comparisons of model/control and momordicine I intervention/model, respectively. GO enrichment analysis suggested that the anti-cardiomyocyte hypertrophic effect of momordicine I may be mainly associated with the regulation of metabolic processes. Based on our transcriptome experiment results as well as literature reports, we selected glycerophospholipid metabolizing enzymes group VI phospholipase A 2 (PLA2G6) and diacylglycerol kinase ζ (DGK-ζ) as targets to further explore the potential mechanism through which momordicine I inhibited ISO-induced cardiomyocyte hypertrophy.Our results demonstrated that momordicine I inhibited ISO-induced upregulations of mRNA levels and protein expressions of PLA2G6 and DGK-ζ. Collectively, momordicine I alleviated ISO-induced cardiomyocyte hypertrophy, which may be related to its inhibition of the expression of glycerophospholipid metabolizing enzymes PLA2G6 and DGK-ζ.

Treadmill exercise alleviates neuropathic pain by regulating mitophagy of the anterior cingulate cortex in rats / 生理学报

This study aimed to investigate the effect of treadmill exercise on neuropathic pain and to determine whether mitophagy of the anterior cingulate cortex (ACC) contributes to exercise-mediated amelioration of neuropathic pain. Chronic constriction injury of the sciatic nerve (CCI) was used to establish a neuropathic pain model in Sprague-Dawley (SD) rats. Von-Frey filaments were used to assess the mechanical paw withdrawal threshold (PWT), and a thermal radiation meter was used to assess the thermal paw withdrawal latency (PWL) in rats. qPCR was used to evaluate the mRNA levels of Pink1, Parkin, Fundc1, and Bnip3. Western blot was used to evaluate the protein levels of PINK1 and PARKIN. To determine the impact of the mitophagy inducer carbonyl cyanide m-chlorophenylhydrazone (CCCP) on pain behaviors in CCI rats, 24 SD rats were randomly divided into CCI drug control group (CCI+Veh group), CCI+CCCP low-dose group (CCI+CCCP0.25), CCI+CCCP medium-dose group (CCI+CCCP2.5), and CCI+CCCP high-dose group (CCI+CCCP5). Pain behaviors were assessed on 0, 1, 3, 5, and 7 days after modeling. To explore whether exercise regulates pain through mitophagy, 24 SD rats were divided into sham, CCI, and CCI+Exercise (CCI+Exe) groups. The rats in the CCI+Exe group underwent 4-week low-moderate treadmill training one week after modeling. The mechanical pain and thermal pain behaviors of the rats in each group were assessed on 0, 7, 14, 21, and 35 days after modeling. Western blot was used to detect the levels of the mitophagy-related proteins PINK1, PARKIN, LC3 II/LC3 I, and P62 in ACC tissues. Transmission electron microscopy was used to observe the ultrastructure of mitochondrial morphology in the ACC. The results showed that: (1) Compared with the sham group, the pain thresholds of the ipsilateral side of the CCI group decreased significantly (P < 0.001). Meanwhile, the mRNA and protein levels of Pink1 were significantly higher, and those of Parkin were lower in the CCI group (P < 0.05). (2) Compared with the CCI+Veh group, each CCCP-dose group showed higher mechanical and thermal pain thresholds, and the levels of PINK1 and LC3 II/LC3 I were elevated significantly (P < 0.05, P < 0.01). (3) The pain thresholds of the CCI+Exe group increased significantly compared with those of the CCI group after treadmill intervention (P < 0.001, P < 0.01). Compared with the CCI group, the protein levels of PINK1 and P62 were decreased (P < 0.001, P < 0.01), and the protein levels of PARKIN and LC3 II/LC3 I were increased in the CCI+Exe group (P < 0.01, P < 0.05). Rod-shaped mitochondria were observed in the ACC of CCI+Exe group, and there were little mitochondrial fragmentation, swelling, or vacuoles. The results suggest that the mitochondrial PINK1/PARKIN autophagy pathway is blocked in the ACC of neuropathic pain model rats. Treadmill exercise could restore mitochondrial homeostasis and relieve neuropathic pain via the PINK1/PARKIN pathway.

OBJECTIVE@#To observe the effect of Tiaoqi Jieyu (regulating qi and relieving depression) acupuncture on the clinical symptoms of treatment-resistant depression (TRD), and to explore the relationship between the acupuncture pain sensitivity and symptom's improvement.@*METHODS@#A total of 78 patients with TRD were randomly divided into an observation group (39 cases, 3 cases dropped off) and a control group (39 cases, 4 cases dropped off). The patients in the control group were treated with medications according to the treatment plan of psychiatrists (at least one medication was 5-hydroxytryptamine reuptake inhibitor). On the basis of the control group, the patients in the observation group were treated with Tiaoqi Jieyu acupuncture, and Baihui (GV 20), Yintang (GV 24+), Yanglingquan (GB 34), Taichong (LR 3), Hegu (LI 4), Neiguan (PC 6), Yinlingquan (SP 9) and Zusanli (ST 36), etc. were selected. The acupuncture was given three times a week. Both groups were treated for 8 weeks. After 8-week treatment, the response rate of Hamilton depression scale-24 (HAMD-24) score after was evaluated in the two groups. The scores of HAMD-24 and Hamilton anxiety scale (HAMA) were compared between the two groups before treatment, after 4, 8-week treatment and 12 weeks after treatment (follow-up). After the first treatment and 8-week treatment, the visual analogue scale (VAS) score in the observation group was evaluated, and the correlation between VAS score after the first treatment and HAMD-24 score before treatment, between VAS score after the first treatment and the course of disease in the observation group was analyzed, and the correlation between difference of VAS after 8-week treatment and after the first treatment and difference of HAMD-24 score before treatment and after 8-week treatment was analyzed.@*RESULTS@#After 8-week treatment, the response rate of HAMD-24 score in the observation group was 52.8% (19/36), higher than 17.1% (6/35) in the control group (P<0.001). Compared before treatment, the scores of HAMD-24 and HAMA in the two groups were decreased after 4-week treatment, 8-week treatment and in follow-up (P<0.05), and those in the observation group were superior to the control group (P<0.05). After 8-week treatment, the acupuncture pain VAS score in the observation group was (5.28±2.13) points, which was higher than (3.33±1.62) points after the first treatment (P<0.001). There was a negative correlation between VAS score after the first treatment and HAMD-24 score before treatment in the observation group (r =-0.486, P=0.003); there was no correlation between acupuncture pain VAS score after the first treatment and the course of disease in the observation group (P>0.05). After 8-week treatment, there was a positive correlation between the difference of VAS score and the difference of HAMD-24 score in the observation group (r =0.514, P=0.001).@*CONCLUSION@#Tiaoqi Jieyu acupuncture could improve the depression and anxiety in patients with TRD, and the symptom's improvement is related to the recovery of acupuncture pain sensitivity.

Activation of TGR5 Attenuates Renal Fibrosis after Renal Ischemia Reperfusion Injury / 中山大学学报(医学科学版)

ObjectiveTo investigate the role of bile acid receptor TGR5 activation in renal fibrosis induced by unilateral ischemia reperfusion injury and contralateral nephrectomy （uIRIx） model. MethodsIn vivo： C57BL/6J mice were randomly divided into Sham group， uIRIx group and uIRIx+ lithcholic acid （LCA） group with 6 mice in each group. Kidney fibrosis was induced by uIRIx model， kidney function was evaluated by blood and urine biochemical indexes， and the degree of kidney injury was evaluated by HE staining. Masson staining and immunohistochemistry were used to evaluate the degree of renal fibrosis， and Western Blotting was used to detect the expression of related index proteins of renal cortical fibrosis. Sham group and uIRIx group were set in TGR5+/+ mice and TGR5-/- mice respectively， with 6 mice in each group. The degree of renal fibrosis in each group was detected by Western Blotting. In vitro： TGF-β1 was administered to induce pro-fibrosis response in human renal tubular epithelial cell line （HK2 cells）， LCA was used for drug intervention， cytoskeleton was labeled with phalloidin-FITC staining and the expression of fibrosis related indicator protein in HK2 cells was detected by Western Blotting. ResultsIn vivo： Compared with the Sham group， plasma creatinine level （P=0.007） and urinary albumin/creatinine ratio （P=0.041） in uIRIx group were significantly increased， renal cortical protein TGR5 expression （P=0.002） was decreased， Fibronectin expression （P=0.020） and COL1A1 expression （P<0.001） were increased. At the same time， the kidney structure was damaged and collagen deposition was aggravated. LCA intervention effectively improved the kidney function and alleviated the degree of kidney injury and fibrosis. TGR5 gene knockout increased uIRIx-induced Fibronectin expression （P<0.001） and COL1A1 expression （P=0.001） compared with TGR5+/+ mice. In vitro： TGF-β1 induced morphological changes of HK2 cells， cytoskeletal depolymerization and recombination， and promoted the up-regulation of fibrosis index protein. LCA effectively inhibited the morphological changes and skeletal depolymerization induced by TGF-β1， and down-regulated the expression of fibrosis related indicator proteins. ConclusionsLCA alleviated renal fibrosis induced by uIRIx model， and knockout of TGR5 gene aggravated uIRIx induced renal fibrosis； In HK2 cells， LCA alleviated fibrogenic reaction induced by TGF-β1.
