Objective:To investigate the association of blood lipids and body mass index (BMI) with hyperuricemia (HUA) in the elderly.Methods:It was a cross-sectional study. A total of 114 391 elderly individuals received health examinations at primary healthcare institutions in Wujin District from January to December in 2022. The health examination included questionnaire survey, physical examination and laboratory examination. The multivariate logistic regression and restricted cubic spline (RCS) plots were used to analyze the association and dose-response relationship of blood lipid and BMI with HUA. The mediating effect model was used to explore the mediation effect of BMI on the association between blood lipid and HUA.Results:Among the 112 415 subjects, 18 506 (16.46%) were checked with HUA. After adjusting for relevant confounders, total cholesterol (TC) ( OR=1.20, 95% CI: 1.16-1.23), triglyceride (TG) ( OR=1.46, 95% CI: 1.44-1.49), high density lipoprotein cholesterol (HDL-C) ( OR=0.74, 95% CI: 0.73-0.76), low density lipoprotein cholesterol (LDL-C) ( OR=1.14, 95% CI: 1.12-1.15) and BMI ( OR=1.42, 95% CI: 1.39-1.44) were all associated with HUA (all P0.05). The RCS analysis revealed that TG, HDL-C, and LDL-C each exhibited a nonlinear dose-response relationship with HUA, the inflection points was 3.00 mmol/L, 1.57 mmol/L and 2.50 mmol/L, respectively (all P-nonlinear0.001). The results of interaction showed that there were additive interaction between high TC( S=1.27 , 95% CI: 1.17-1.37), high TG( S=1.32 , 95% CI: 1.25-1.40), high LDL-C( S=1.23 , 95% CI: 1.14-1.34) and overweight/obesity with HUA (all P0.05). The results of mediation effect analysis showed that the mediation effect of BMI on the association between blood lipids (HDL-C, LDL-C, TG and TC) and HUA, from high to low, were as follows: 22.5% (95% CI: 20.8%-24.2%), 13.9% (95% CI: 12.0%-16.2%), 13.5% (95% CI: 12.7%-14.4%) and-3.9% (95% CI:-6.6%--1.8%). Conclusion:The blood lipid levels and BMI are positively correlated with HUA in the elderly.

ObjectiveTo investigate the analgesic effect and mechanism of Osteoking （OK） on nerve compression in lumbar disc herniation. MethodThe rat model of chronic compression of dorsal root ganglion （CCD） was established to simulate clinical lumbar disc herniation. The CCD rats were randomly divided into model group， low， medium， and high dose OK groups （1.31， 2.63， 5.25 mL·kg^-1·d^-1）， and pregabalin group （5 mg·kg^-1）， with eight rats in each group. Another eight SD rats were taken as the blank group， and the same volume of normal saline was given by gavage. Behavioral tests， side effect evaluation， network analysis， Western blot， immunofluorescence， and antagonist application were used to explore the effect. ResultCompared with the blank group， the mechanical hyperalgesia threshold， thermal hyperalgesia threshold， and the expression of inflammatory factors in the spinal dorsal horn of the model group are significantly increased （P<0.01）， and the related indicators of the affected foot footprints are significantly down-regulated （P<0.01）. The expression of signal transducer and activator of transcription 3 （STAT3）， vascular endothelial growth factor A （VEGFA）， and phosphorylated extracellular regulated protein kinase （p-ERK） in microglia in the spinal dorsal horn is significantly increased in the model group （P<0.01）. Compared with the model group， low， medium， and high dose OK groups can increase the mechanical hyperalgesia and thermal hyperalgesia thresholds of CCD rats （P<0.05， P<0.01） in a dose-dependent manner， improve the gait of CCD rats （P<0.05， P<0.01）， and reduce the expression of inflammatory factors in the spinal dorsal horn （P<0.05， P<0.01）. The expression of STAT3， VEGFA， and p-ERK in the spinal dorsal horn microglia of CCD rats is significantly decreased （P<0.05， P<0.01）， and the acetic acid-induced nociceptive response in rats is effectively reduced （P<0.05， P<0.01）. In addition， there is no tolerance. The results of the body mass test， organ index， forced swimming， and rotation show that OK has no obvious toxic or side effects. Further antagonist experiments show that MRS1523 and RS127445 can reverse the transient analgesic effect of OK compared with the high dose OK group （P<0.01）. ConclusionOK has a good analgesic effect on the CCD model without obvious toxic side effects， and its mechanism may be related to the activation of ADORA3 and HTR2B and the inhibition of STAT3， VEGFA， p-ERK， and other elements in microglia.

Aim To explore the effect of ZLY18 on angiotensin II-induced cardiac fibrosis and the underlying mechanism. Methods Ang II was used to induce cardiac fibrosis in vitro and in vivo. Cardiac fibroblasts were divided into blank control group, model group and medicine group. The medicine group was subdivided into ZLY18(L)group, ZLY18(M)group and ZLY18(H)group. Compound ZLY18 was given 1, 2, 5 μmol·L-1 respectively. C57BL/6 mice were randomly divided into control group, model group and medicine group. The medicine group were subdivided into ZLY18(L)group, ZLY18(M)group and ZLY18(H)group. Compound ZLY18 was given 10,20 and 50 mg·kg-1 respectively. Both the model group and the medicine group were given with Ang II to induce cardiac fibrosis. The changes of protein levels were detected by Western blot and immunofluorescence. The changes of cardiac function indexes in C57BL/6 mice were detected by small animal echocardiography. The morphology, cell arrangement and collagen fibers of cardiac fibroblasts were observed by tissue section staining and other methods. Results The model of Ang II-induced myocardial fibrosis was successfully established at the cell and animal levels, and ZLY18 treatment improved the elevated fibrosis-related protein caused by Ang II and abnormal cardiac function in mice. Moreover, ZLY18 was able to inhibit the increased phosphorylation of TGF-1 and Smad3 caused by Ang II and increased Smad2/3 nuclear entry, suggesting that the antifibrotic effect of ZLY18 might be related to the activation of TGF-1/Smads signaling pathway. Conclusions ZLY18 has a protective effect on Ang II-induced cardiac fibrosis. ZLY18 may inhibit TGF-β/Smads signaling pathway activation to exert anti-fibrotic effects.

Colon cancer-related anemia (CCRA) is mainly caused by systemic inflammation, intestinal bleeding, iron deficiency and chemotherapy-induced myelosuppression in colon cancer. However, the best therapeutic schedule and related mechanism on CCRA were still uncertain. Studies on blood enrichment and anti-tumor effects of combined Danggui Buxue Decoction (DBD), Fe and rhEPO based on CCRA and gut microbiota modulation were conducted in this paper. Here, CCRA model was successfully induced by subcutaneous inoculation of CT-26 and i.p. oxaliplatin, rhEPO + DBD high dosage + Fe (EDF) and rhEPO + DBD high dosage (ED) groups had the best blood enrichment effect. Attractively, EDF group also showed antitumor activity. The sequencing results of gut microbiota showed that compared to P group, the relative abundances of Lachnospiraceae and opportunistic pathogen (Odoribacter) in ED and EDF groups were decreased. Interestingly, EDF also decreased the relative abundances of cancer-related bacteria (Helicobacter, Lactococcus, Alloprevotella) and imbalance-inducing bacteria (Escherichia-Shigella and Parabacteroides) and increased the relative abundances of butyrate-producing bacteria (Ruminococcaceae_UCG-014), however, ED showed the opposite effects to EDF, this might be the reason of the smaller tumor volume in EDF group. Our findings proposed the best treatment combination of DBD, rhEPO and Fe in CCRA and provided theoretical basis and literature reference for CCRA-induced intestinal flora disorder and the regulatory mechanism of EDF.

Objective:To observe the controlling effect of addition and subtraction therapy of Xuanbi tang on knee osteoarthritis of rheumatic fever arthralgia type (KOA) at attack stage and to investigate the influence to acute inflammation factors. Method:One hundred and twenty-eight patients were randomly divided into control group and observation group (1∶1) by random number table with SAS software. The patients in both groups got celecoxib capsules, 0.2 g/time, 1 time/day, glucosamine hydrochloride capsule, 1 grain/time, 2 times/day. Patients in control group addiiontally got Simiaowan, 6 g/time, 2 times/day. Patients in observation group got addition and subtraction therapy of Xuanbitang, 1 dose/day, with a treatment course of 2 weeks in both groups. Visual analogue scale of pain (VAS) was used to discuss pain degree of knee joint, and the VAS scores during activity and resting state were recorded every day, and the time to pain relief and time to pain disappearance were also recorded. Before and after treatment, the scores of osteoarthritis index visual scale of Western Ontario and McMaster University (WOMAC), scores of swelling degree and scores of rheumatism heat arthralgia syndrome were graded. The levels of high sensitive C-reactive protein (hs CRP), interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and serum matrix metalloproteinase-3 (MMP-3) were detected before and after treatment. In addition, safety was evaluated and discussed. Result:The comprehensive total effective rate in observation group was 95.00% (57/60), higher than 83.05% (49/59) in control group (P<0.05). At the third, seventh, tenth, fourteenth day after treatment, scores of knee joint pain degree in observation group were lower than those in control group (P<0.01). Time to pain relief and time to pain disappearance were shorter than those in control group (P<0.01). Scores of WOMAC, swelling degree and rheumatism heat arthralgia syndrome were all lower than those in control group (P<0.01). Levels of hs-CRP, IL-1β, IL-6, TNF-α and MMP-3 were lower than those in control group (P<0.01). In addition, there was no adverse reaction related to Xuanbitang. Conclusion:Addition and subtraction therapy of Xuanbitang can relieve pain, swelling and other symptoms, improve knee joint function, shorten the course of disease, and control the acute inflammatory reaction, with significant clinical efficacy and safety.
