Objective:To observe the protective effects of Zhiganqing Prescription on the liver of C57BL/6J non-alcoholic fatty liver disease (NAFLD) mice induced by high fat diet and its effects on PI3K/Akt/FoxO1 signaling pathway, insulin resistance (IR) and gluconogenesis.Methods:A total of 48 8-week-old male C57BL/6J mice were divided into control group ( n=8) and modeling group ( n=40) according to random number table method. The control group was fed with ordinary diet, and the model group was fed with high-fat diet. The NAFLD model was established after 8 weeks of feeding. The modeling group was divided into model group, Pioglitazone group, Zhiganqing Prescription low-, medium-, and high-dosage group ( n=8 in each group) according to random number table method, and drug intervention lasted for 8 weeks. The body mass of mice was measured regularly during administration. Fasting blood glucose (FBG) levels were measured at 0 and 8 weeks of administration, and oral glucose tolerance tests (OGTT) were conducted. After the experiment, serum levels of GPT, GOT, TC, TG, LDL-C, HDL-C, FINS and C-P were detected and HOMA-IR was calculated. The pathological morphology of liver was observed by HE and PAS staining. The expression levels of PI3K and p-Akt were detected by IHC staining. The protein expression levels of PI3K, Akt, p-Akt, FoxO1, p-FoxO1, G6PC and PCK1 were detected by Western blot. Results:Compared with model group, the body weight of mice in each administration group decreased at 4, 6 and 8 weeks ( P<0.05 or P<0.01). At the 8th week of administration, the levels of FBG and OGTT AUC in each administration group decreased ( P<0.05 or P<0.01), the levels of GPT, TC, TG and LDL-C decreased ( P<0.01), and the GOT levels in Zhiganqing Prescription medium- and high-dosage groups decreased ( P<0.01). The HDL-C level in Zhiganqing Prescription medium-dosage group decreased ( P<0.05 or P<0.01), and the HOMA-IR level in Zhiganqing Prescription low- and medium-dosage groups decreased ( P<0.05 or P<0.01). The levels of FINS and C-P in each administration group increased ( P<0.05 or P<0.01), and the expressions of PI3K protein and p-Akt/Akt, p-FoxO1 /FoxO1 protein in liver tissues increased ( P<0.05 or P<0.01). The protein expressions of G6PC and PCK1 decreased ( P<0.05 or P<0.01). Conclusion:Zhiganqing Prescription can effectively control the body mass, blood glucose, liver function and blood lipids of NAFLD mice, improve IR and gluconeogenesis, the mechanism of which may be related to the activation of PI3K/Akt/FoxO1 signaling pathway.

ObjectiveTo test the inter-tester reliability and test-retest reliability of MyotonPRO for evaluating neck and shoulder muscle performance parameters in patients with unilateral chronic neck pain, observe the difference of muscle performance between the healthy and affected sides of patients with chronic neck pain, and analyze the factors that cause the imbalance of muscle performance in patients with chronic neck pain. MethodsFrom January to June, 2023, 32 patients with unilateral chronic neck pain in Guangdong Second Traditional Chinese Medicine Hospital were selected. Two testers used the same MyotonPRO equipment to measure the muscle tone, muscle hardness and muscle elasticity on both sides of the sternocleidomastoid muscle and the upper trapezius muscle in the relaxed position. Tester 1 repeated the measurement after an interval of 30 minutes, and Tester 2 was measured within the time interval between the two measurements of Tester 1. The intraclass correlation coefficient (ICC), standard error of mean (SEM) and minimum detectable change (MDC) were calculated simultaneously. The measurement results were plotted into Bland-Altman diagram and systematic bias analysis was performed. The difference in muscle characteristics between the affected side and the healthy side was compared. At the same time, the Visual Analogue Scale (VAS) score and body mass index (BMI) of the subjects were collected for correlation analysis. ResultsExcept the sternocleidomastoid muscle elasticity of the affected side (ICC = 0.697), the inter-tester reliability of all other parameters was high to very high (ICC = 0.719 to 0.952, SEM = 0.04 to 6.53, MDC = 0.12 to 18.11). The test-retest reliability of all parameters was high (ICC = 0.883 to 0.981, SEM = 0.03 to 5.72, MDC = 0.09 to 15.84). Bland-Altman plot analysis showed that the scatter distribution was consistent. The muscle tone, muscle hardness and muscle elasticity of sternocleidomastoid muscle and upper trapezius muscle were higher on the affected side than on the healthy side (t > 2.846, P < 0.05). The asymmetry index of tension, hardness and elasticity of upper trapezius muscle and sternocleidomastoid muscle was significantly positively correlated with VAS score and BMI (r > 0.385, P < 0.05). ConclusionMyotonPRO has good inter-tester reliability and retest reliability in evaluating the muscle performance of both sides of patients with chronic neck pain. The muscle tone, muscle hardness and muscle elasticity of sternocleidomastoid muscle and upper trapezius muscle on the affected side were higher than on the healthy side, and the difference of muscle performance was positively correlated with pain and BMI.

The NLRP3 inflammasome's core and most specific protein, NLRP3, has a variety of functions in inflammation-driven diseases. Costunolide (COS) is the major active ingredient of the traditional Chinese medicinal herb Saussurea lappa and has anti-inflammatory activity, but the principal mechanism and molecular target of COS remain unclear. Here, we show that COS covalently binds to cysteine 598 in NACHT domain of NLRP3, altering the ATPase activity and assembly of NLRP3 inflammasome. We declare COS's great anti-inflammasome efficacy in macrophages and disease models of gouty arthritis and ulcerative colitis via inhibiting NLRP3 inflammasome activation. We also reveal that the α-methylene-γ-butyrolactone motif in sesquiterpene lactone is the certain active group in inhibiting NLRP3 activation. Taken together, NLRP3 is identified as a direct target of COS for its anti-inflammasome activity. COS, especially the α-methylene-γ-butyrolactone motif in COS structure, might be used to design and produce novel NLRP3 inhibitors as a lead compound.

Excessive N-acetyl-p-benzoquinone imine(NAPQI)formation is a starting event that triggers oxidative stress and subsequent hepatocyte necrosis in acetaminophen(APAP)overdose caused acute liver failure(ALF).S-glutathionylation is a reversible redox post-translational modification and a prospective mechanism of APAP hepatotoxicity.Glutaredoxin-1(Glrx1),a glutathione-specific thioltransferase,is a primary enzyme to catalyze deglutathionylation.The objective of this study was to explored whether and how Glrx1 is associated with the development of ALF induced by APAP.The Glrx1 knockout mice(Glrx1-/-)and liver-specific overexpression of Glrx1(AAV8-Glrx1)mice were produced and underwent APAP-induced ALF.Pirfenidone(PFD),a potential inducer of Glrx1,was administrated preceding APAP to assess its protective effects.Our results revealed that the hepatic total protein S-glutathionylation(PSSG)increased and the Glrx1 level reduced in mice after APAP toxicity.Glrx1-/- mice were more sensitive to APAP overdose,with higher oxidative stress and more toxic metabolites of APAP.This was attributed to Glrx1 deficiency increasing the total hepatic PSSG and the S-glutathionylation of cytochrome p450 3a 11(Cyp3a11),which likely increased the activity of Cyp3a11.Conversely,AAV8-Glrx1 mice were defended against liver damage caused by APAP overdose by inhibiting the S-glutathionylation and activity of Cyp3a11,which reduced the toxic metabolites of APAP and oxidative stress.PFD precede administration upregulated Glrx1 expression and alleviated APAP-induced ALF by decreasing oxidative stress.We have identified the function of Glrx1 mediated PSSG in liver injury caused by APAP overdose.Increasing Glrx1 expression may be investigated for the medical treatment of APAP-caused hepatic injury.
