Gouty arthritis （GA） is caused by monosodium urate（MSU） deposition due to purine metabolism disorders. In traditional Chinese medicine （TCM）， it falls under the category of "dampness-heat Bi syndrome"， with core pathogenesis involving dampness-heat accumulation and dysfunction of the spleen and kidney. The dampness-heat syndrome is the most common and the primary syndrome type during acute attacks. In Western medicine， GA is associated with purine metabolism imbalance and inflammation triggered by MSU crystals， involving pathways such as NOD-like receptor protein 3 （NLRP3） inflammasome activation and Toll-like receptor 2/4 （TLR2/4） signaling. Clinically， colchicine and similar drugs are commonly used to treat GA， although long-term use carries potential side effects. Ermiao Formula analogs originate from ancient prescriptions， including Ermiao， Sanmiao， and Simiao compound formulas. All contain Atractylodis Rhizoma and Phellodendri Chinensis Cortex. Ermiaowan follow a 1∶1 formulation ratio. Sanmiaowan add Cyathulae Radix. Simiaowan further incorporate Coicis Semen. These formulas are rich in active ingredients， including alkaloids， terpenoids， flavonoids， and sterols， and treat GA through multi-component， multi-pathway， and multi-target mechanisms. Ermiaosan primarily exerts anti-inflammatory effects by inhibiting pathways such as TLR4/nuclear factor kappa-B （NF-κB） or regulating immune responses to reduce the release of inflammatory mediators， while also suppressing xanthine dehydrogenase （XDH） and xanthine oxidase （XO） activity to decrease uric acid production. Sanmiaowan enhance uric acid-lowering and anti-inflammatory effects through the guiding herb Cyathulae Radix， while also protecting cartilage from damage. Simiaowan utilizes Coicis Semen to regulate intestinal flora， alleviate dampness-heat symptoms， and exert multi-pathway anti-inflammatory and uric acid-lowering effects. The active ingredients contribute differently to uric acid metabolism regulation， anti-inflammation， antioxidant activity， and bone repair， resulting in varying therapeutic effects due to differences in formula composition. In summary， formulas derived from Ermiaosan demonstrate significant efficacy in treating dampness-heat type GA. This review summarizes their research progress and mechanisms， providing a reference for clinical application， new drug development， and further studies.

The difficulty of wound healing in patients is a difficult problem that doctors in all clinical departments may encounter, and there is still no good solution. Resveratrol is a kind of natural active substance, which has anti-inflammatory, antioxidant, antibacterial, and angiogenesis promoting effects, and is a potential drug to promote wound healing. However, the clinical application of resveratrol is limited due to its low bioavailability. In this review, the molecular mechanism of resveratrol in promoting wound healing and its administration methods in wound treatment were reviewed to provide ideas for the redevelopment of resveratrol.

Objective:To evaluate the arousal effect of plantar reflex area and acupoint massage combined with music therapy in patients with brain trauma and coma.Methods:From March 2022 to March 2023, 90 patients with brain trauma and coma who were treated in the Neurosurgery Intensive Care Unit of Tangshan Gongren Hospital in Hebei Province were selected as the research subject. According to the random number table method, patients were divided into a control group, experimental group 1, and experimental group 2, with 30 cases in each group. The control group received routine nursing for brain trauma, while the experimental group 1 received music therapy with the natural voice on the basis of the control group. The experimental group 2 was treated with plantar reflex area and acupoint massage treatment on the basis of the experimental group 1. This study compared the Glasgow Coma Scale (GCS) scores and Coma Recovery Scale-Revised (CRS-R) scores of three groups of patients before and after intervention.Results:After 2, 4, and 6 weeks of intervention, the GCS scores and CRS-R scores of patients in experimental group 2 were higher than those in the control group and experimental group 1, with statistically significant differences ( P<0.05) . Conclusions:The combination of plantar reflex area and acupoint massage with music therapy has a certain arousal effect on patients with brain trauma and coma, and can be promoted and applied in clinical practice.

Heart failure is the leading cause of death worldwide. Compound Danshen Dripping Pill (CDDP) or CDDP combined with simvastatin has been widely used to treat patients with myocardial infarction and other cardiovascular diseases in China. However, the effect of CDDP on hypercholesterolemia/atherosclerosis-induced heart failure is unknown. We constructed a new model of heart failure induced by hypercholesterolemia/atherosclerosis in apolipoprotein E (ApoE) and LDL receptor (LDLR) dual deficient (ApoE^-/-LDLR^-/-) mice and investigated the effect of CDDP or CDDP plus a low dose of simvastatin on the heart failure. CDDP or CDDP plus a low dose of simvastatin inhibited heart injury by multiple actions including anti-myocardial dysfunction and anti-fibrosis. Mechanistically, both Wnt and lysine-specific demethylase 4A (KDM4A) pathways were significantly activated in mice with heart injury. Conversely, CDDP or CDDP plus a low dose of simvastatin inhibited Wnt pathway by markedly up-regulating expression of Wnt inhibitors. While the anti-inflammation and anti-oxidative stress by CDDP were achieved by inhibiting KDM4A expression and activity. In addition, CDDP attenuated simvastatin-induced myolysis in skeletal muscle. Taken together, our study suggests that CDDP or CDDP plus a low dose of simvastatin can be an effective therapy to reduce hypercholesterolemia/atherosclerosis-induced heart failure.

OBJECTIVE: To explore the effect of leucine-rich α-2-glycoprotein (LRG1) derived from hepatocytes on activation of hepatic M1 Kupffer cells. METHODS: A metabolic dysfunction-associated fatty liver disease (MAFLD) model was established in BALB/c mice by high-fat diet (HFD) feeding for 16 weeks. Oleic acid was used to induce steatosis in primary cultures of mouse hepatocytes. The mRNA and protein expressions of LRG1 in mouse liver tissues and hepatocytes were detected by real-time PCR and Western blotting. Primary hepatic macrophages were stimulated with the conditioned medium (CM) from steatotic hepatocyte along with LRG1 or transforming growth factor-β1 (TGF-β1), or both for 24 h, and the expression levels of inducible nitric oxide synthase (iNOS) was detected with Western botting, and the mRNA expressions of iNOS, chemokine ligand 1 (CXCL-1) and interleukin-1β (IL-1β) were measured by RT-PCR. The MAFLD mice were injected with LRG1 (n=6), TGF-β1 (n=6), or both (n=6) through the caudal vein, and the live tissues were collected for HE staining and immumohistochemical detection of F4/80 expression; the mRNA expressions of iNOS, CXCL-1 and IL-1β in liver tissues were detected using RT-PCR. RESULTS: The mRNA and protein expression levels of LRG1 were significantly downregulated in the liver tissues of MAFLD mice and steatotic hepatocytes (P < 0.05). Treatment of the hepatic macrophages with CM from steatosis hepatocytes significantly enhanced the mRNA expression levels of iNOS, CXCL-1 and IL-1β, and these changes were significantly inhibited by the combined treatment with TGF-β1 and LRG1 (P < 0.05). In MAFLD mice, injections with either LRG1 or TGF-β1 alone reduced hepatic lipid deposition and intrahepatic macrophage infiltration, and these effects were significantly enhanced by their combined treatment, which also more strongly inhibited the mRNA expression levels of iNOS, CXCL-1 and IL-1β (P < 0.05). CONCLUSION LRG1 inhibits hepatic macrophage infiltration by enhancing TGF-β1 signaling to alleviate fatty liver inflammation in MAFLD mice.

For the ideal preclinical animal model of hepatitis B virus (HBV), its hepatocytes should allow HBV entry and cccDNA generation and have both innate and adaptive immune systems. However, HBV only naturally infects humans and chimpanzees due to highly restricted species specificity, and no effective model has been established so far to truly reflect the immune mechanism and pathogenesis of HBV infection. This article reviews five commonly used mouse models, i.e., HBV transgenic model, HBV plasmid DNA hydrodynamic injection model, AAV-HBV transfection model, cccDNA surrogate model, and human-mouse chimeric liver model, and looks forward to the new models that will appear in the future, such as hNTCP transgenic cynomolgus monkey, rhesus monkey, or pig models, so as to provide a reference for researchers to select these models, accelerate the process of drug screening, validate new therapies, and better solve the problems of HBV biological pathogenesis.

Objective:To investigate the correlation between acoustic radiation force impulse imaging(ARFI) and reserve function of liver and the feasibility of liver reserve function assessment by ARFI.Methods:According to the inclusion criteria, 74 patients were screened and 71 patients were finally enrolled from Henan Province People′s Hospital during June 2017 and June 2019. The portal vein diameter (D PV), spleen length (L SP) were measured by two-dimensional ultrasound. The liver shear wave velocity (LSWV) and spleen shear wave velocity (SSWV) were measured by ARFI. Serological markers were checked, and the indocyanine green (ICG)15-minute retention rate (ICG R15) was measured by excretion test. The patients were divided into ICG R15<10% group and ICG R15≥10% group, the difference of the measurements between two groups were calculated, the correlations of the measurements and ICG R15 were analyzed. LSWV diagnostic performance for liver reserve function was evaluated by the ROC curve. Results:There were significant differences in LSWV, D PV, SSWV, L SP, aspartate transaminase(AST), alkaline phosphatase(ALP), y-glutamyl transpeptidase(γ-GGT) and albumin (ALB) between ICG R15<10% group and ICG≥10% group( P<0.05), but no significant differences in other measurements( P>0.05). The correlations between ICG R15 and LSWV( r=0.673, P<0.001), D PV( r=0.355, P<0.05), SSWV( r=0.384, P<0.05), L SP( r=0.403, P<0.001), ALP( r s=0.245, P<0.05) and ALB( r s=-0.390, P<0.05) were statistically significant. The ROC curve showed high diagnostic performance for liver reserve function assessment by LSWV. The area under the ROC curve was 0.903 (95% CI=0.810-0.961, P<0.01), and the cut-off value was 2.15 m/s (sensitivity 84.6%, specificity 86.7%). Conclusions:The LSWV can evaluate the reserve function and it is a useful supplement to the ICG excretion experiment.

Background and purpose:Perioperative hypothermia will affect the prognosis of cancer patients. Amino acid infusion can increase the core temperature by endogenous thermogenesis. And the forced-air warming system has gained high acceptance as a measure for rewarming. This study aimed to find out whether amino acid infusion was effective to treat postoperative hypothermia and how well the treatment effect was when compared with the forced-air warming system.Methods:Fifty-seven ASAⅠ orⅡ patients aged 18-60 years undergoing elective esophageal or gastric cancer operation under epidural-general anesthesia and whose core temperature were below 36℃. When admitted to the recovery room wererandomly divided into 3 groups (n=19): GroupⅠ received intravenous infusion of mixed amino acid at a rate of 2 mL·kg-1·h-1 (A); GroupⅡ received a forced-air system (B); groupⅢreceived no therapy (C). Rectal temperature and thermal comfort were recorded per 5 min during the ifrst 1 h and oral temperature and thermal comfort were recorded at the 2, 6 and 24 h. ABG was recorded when patients were admitted to the recovery room and at the ifrst hour.Results:At the ifrst hour, the rectal temperature and thermal comfort of groups A and B were higher when compared with group C (P<0.05), and there was no difference between groups A and B (P>0.05). At the second and sixthhour, the temperature and thermal comfort of group A were higher when compared with group B and C (P<0.05), and there was no difference between groups B and C (P>0.05). At the 24th hour, there were no statistically signiifcant differences in the temperature and thermal comfort among the three groups (P>0.05).
Conclusion:The rewarming effect of infusion of mixed amino acid is better than that of the forced-air warming system. It is the more effective and convenient method to rewarm the postoperative hypothermia.
