Objective:To study the content determination method for the effective components in WudangⅡFlos lonicerae Caulis to lay foundation for the quality evaluation. Methods: An ultrasonic method was used. The effects of extraction solvent, ultrasonic time, ultrasonic power and ratio of solid to liquid on the contents of rutin and mignonette nucleoside were studied, and the extraction conditions were optimized by a 4-factor and 3-level orthogonal experiment. The chromatographic conditions were as follows:a Phenome-nex Luna-C18(250 mm ×4.60 mm, 5 μm) column was adopted for chlorogenic acid, and a Fortis Xi Phenyl column (250 mm × 4. 6 mm, 5 μm) was used for rutin, loganin and luteoloside;the mobile phase was acetonitrile (B)-0. 4% phosphoric acid (C) solu-tion (15 ∶85) for chlorogenic acid and loganin, and acetonitrile (B) -0. 5% glacial acetic acid aqueous solutjion (D) with gradient e-lution for rutin and luteoloside;the column temperature was 30℃, and the detection wavelength was 327,237,354 and 348 nm, re-spectively. Results:The optimum extraction conditions for rutin and luteoloside from WudangⅡFlos lonicerae Caulis were as follows:the extraction solvent was 60% ethanol, the solid-liquid ratio was 1 ∶30, the ultrasonic power and the ultrasonic time were 350 W and 50 min for rutin, and 250W and 60min for luteoloside. The content of chlorogenic acid, loganin, rutin and luteoloside was 10. 27, 6. 33, 0. 401 and 0. 450 mg·g-1 in the samples, respectively. Conclusion:The method is simple and convenient, accurate and re-producible, which can be used to control the quality of WudangⅡFlos lonicerae Caulis and provide reference for the further develop-ment.

Objective To establish a rapid and sensitive liquid chromatograph-mass spectrometry (LC-MS/MS) method for the determination of thiabendazole in honeysuckle flowers. Methods The acetic ether was selected as extraction solvent. The mass spectrometer analysis was conducted in the positive ionization electrospray mode using SIM. The transitions m/z 202→175 was used to quantify thiabendazole. Results The satisfactory linearity was obtained in the range of 0.1×10-5-2×10-5mg for thiabendazole (r=0.999 5), and the limit of detection (LOD) of 10.0 ng/ml and the mean recovery of 93.70% were obtained by this LC-MS/MS method. Conclusions The method of LC-MS/MS is sensitive, simple and accurate, and it proved to be suitable for the determination of thiabendazole in Honeysuckle flowers.

Objective? To explore the application effects of nurse-patient co-management intervention in arrhythmia patients with intravenous amiodarone. Methods? From October 2015 to September 2017, we selected 126 arrhythmia patients with amiodarone of the First Affiliated Hospital of Xinjiang Medical University as subjects by convenience sampling. All of the subjects were randomly divided into intervention group and control group, 63 cases in each group. Control group adopted routine nursing, while intervention group carried out nurse-patient co-management intervention. We compared the differences in the incidence of phlebitis, blood pressure, heart rate, adverse reactions, hospital stay and satisfaction of patients both groups. Results? The incidence of phlebitis and its cumulative occurrence time of intervention group were lower than those of control group (P< 0.05);the level of blood pressure after using medication of patients in intervention group was higher than that in control group, and incidence of gastrointestinal adverse reaction and hospital stay of patients in intervention group were less than those in control group (P<0.05). Satisfaction with nursing of intervention group was higher than that of control group (P<0.05). Conclusions? Nurse-patient co-management intervention can increase the safety of arrhythmia patients with amiodarone, reduce the incidence of adverse reactions and improve patient satisfaction which is worthy of being widely used in clinical application.

Objective:To study the effect of atractylodes lactideⅠ,Ⅱand Ⅲ on the expression of cytokines by inducing M1 type macrophage model. Methods:Apoptotic macrophages were induced by sodium thioglycolate, and then the rat peritoneal inflammatory macrophages were purified by a differential adherence method. The expression of macrophage marker antigen (ED1) was identified by flow cytometry macrophages. Tumor necrosis factor ( TNF-α) , proinflammatory cytokines ( IL-1β) and interleukin-6 ( IL-6 ) were measured by ELISA in vitro. The levels of expression of arginase 1, inducible nitric oxide synthase (iNOS), inflammatory cytokines (IL-1β) chemokine (CCL22) and transforming growth factor (TGF-β) in inflammatory macrophages were determined by RT-PCR. Results:As for the purification of cultured rat inflammatory macrophage expressing ED1, atractylenolideⅠand Ⅲ could reduce the ex-pression levels of iNOS and IL-1βand increase the expression levels of arginase1 CCL22 and TGF-β. The release of inflammatory fac-tor IL-1β decreased, and the release levels of TGF-β and chemokines CCL22 were promoted(P<0. 05). Atropine lactoneⅠ and Ⅲ had significant inhibitory effects on TNF-α, IL-1β and IL-6 in macrophages(P<0. 05). Conclusion: Atractylodes lactone Ⅰand Ⅲ with anti-inflammatory activity can promote the expression of cytokines in inflammatory macrophages, while the change induced by at-ractylaxanthin Ⅱ is not obvious.

Background:
s/Aims: Transmembrane 6 superfamily member 2 (TM6SF2) E167K variant is closely associated with the occurrence and development of metabolic dysfunction-associated steatotic liver disease (MASLD). However, the role and mechanism of TM6SF2 E167K variant during MASLD progression are not yet fully understood.
Methods:
The Tm6sf2167K knock-in (KI) mice were subjected to high-fat diet (HFD). Hepatic lipid levels of Tm6sf2167K KI mice were detected by lipidomics analysis. Thin-layer chromatography (TLC) was used to measure the newly synthesized triglyceride (TG) and phosphatidylcholine (PC).
Results:
The TM6SF2 E167K variant significantly aggravated hepatic steatosis and injury in HFD-induced mice. Decreased polyunsaturated PC level and increased polyunsaturated TG level were found in liver tissue of HFDinduced Tm6sf2167K KI mice. Mechanistic studies demonstrated that the TM6SF2 E167K variant increased the interaction between TM6SF2 and PNPLA3, and impaired PNPLA3-mediated transfer of polyunsaturated fatty acids (PUFAs) from TG to PC. The TM6SF2 E167K variant increased the level of fatty acid-induced malondialdehyde and reactive oxygen species, and decreased fatty acid-downregulated cell membrane fluidity. Additionally, the TM6SF2 E167K variant decreased the level of hepatic PC containing C18:3, and dietary supplementation of PC containing C18:3 significantly attenuated the TM6SF2 E167K-induced hepatic steatosis and injury in HFD-fed mice.
Conclusions
The TM6SF2 E167K variant could promote its interaction with PNPLA3 and inhibit PNPLA3-mediated transfer of PUFAs from TG to PC, resulting in the hepatic steatosis and injury during MASLD progression. PC containing C18:3 could act as a potential therapeutic supplement for MASLD patients carrying the TM6SF2 E167K variant.
