ObjectiveTo explore the effectiveness and potential mechanism of Shugan Jianpi Granules （疏肝健脾颗粒） combined with Chushi Zhiyang Ointment （除湿止痒软膏） in the treatment of atopic dermatitis with sleep disturbance of liver constraint and spleen deficiency syndrome. MethodsSixty-six patients with atopic dermatitis combined with sleep disturbance of liver constraint and spleen deficiency syndrome were randomly divided into 33 cases each in the treatment group and the control group. Both groups were treated with Chushi Zhiyang Ointment for external use. The treatment group additionally received Shugan Jianpi Granules orally， one dose per day； and the control group received cetirizine hydrochloride tablets orally， 10mg per day， taken before bedtime. Both groups were under the treatment for 4 weeks. Clinical effectiveness was evaluated after treatment， and the SCORing Atopic Dermatitis （SCORAD） index， pruritus visual analog scale （VAS） score， Insomnia Severity Index （ISI） score， and Pittsburgh Sleep Quality Index （PSQI） score were recorded before and after treatment， and serum levels of melatonin （MLT）， interleukin-4 （IL-4）， interleukin-6 （IL-6）， interleukin-13 （IL-13）， and tumor necrosis factor-α （TNF-α） were measured. The patients were also tested for blood routine， liver function and kidney function before and after treatment， and the occurrence of adverse events was also observed. ResultsThe total effective rate in the treatment group （90.63%， 29/32） was significantly higher than that in the control group （66.67%， 20/30， P＜0.05）. After the interventions， the scores for SCORAD， VAS， ISI， and PSQI， as well as the levels of IL-4， IL-6， IL-13， and TNF-α， were significantly reduced in both groups. In contrast， the MLT levels in treatment group significantly elevated compared to that before treatment （P＜0.05）. Comparing between the two groups after treatment， the scores of SCORAD， ISI， PSQI， and VAS， as well as the levels of serum IL-4 and IL-13 in the treatment group were significantly lower than those in the control group， while the MLT levels were markedly higher than that in the control group （P＜0.05 or P＜0.01）. There was no obvious abnormality in blood routine， liver function and kidney function in both groups when compared before and after treatment. The incidence rate of adverse reactions was 9.38% （3/32） in the treatment group and 13.33% （4/30） in the control group， and the difference between groups showed no statistical difference （P＞0.05）. ConclusionOn the basis of topical application of Chushi Zhiyang Ointment， the combined application of Shugan Jianpi Granules can significantly alleviate the degree of skin lesions and itching， and improve the quality of sleep in atopic dermatitis patients with sleep disturbance of liver constraint and spleen deficiency syndrome， and its mechanism may be related to regulating the immune balance， reducing the secretion of inflammatory factors， and elevating the level of MLT.

OBJECTIVE: To investigate the anti-inflammatory effect of rutaecarpine (RUT) on monosodium urate crystal (MSU)-induced murine peritonitis in mice and further explored the underlying mechanism of RUT in lipopolysaccharide (LPS)/MSU-induced gout model in vitro. METHODS: In MSU-induced mice, 36 male C57BL/6 mice were randomly divided into 6 groups of 8 mice each group, including the control group, model group, RUT low-, medium-, and high-doses groups, and prednisone acetate group. The mice in each group were orally administered the corresponding drugs or vehicle once a day for 7 consecutive days. The gout inflammation model was established by intraperitoneal injection of MSU to evaluate the anti-gout inflammatory effects of RUT. Then the proinflammatory cytokines were measured by enzyme-linked immunosorbent assay (ELISA) and the proportions of infiltrating neutrophils cytokines were detected by flow cytometry. In LPS/MSU-treated or untreated THP-1 macrophages, cell viability was observed by cell counting kit 8 and proinflammatory cytokines were measured by ELISA. The percentage of pyroptotic cells were detected by flow cytometry. Respectively, the mRNA and protein levels were measured by real-time quantitative polymerase chain reaction (qRT-PCR) and Western blot, the nuclear translocation of nuclear factor κB (NF-κB) p65 was observed by laser confocal imaging. Additionally, surface plasmon resonance (SPR) and molecular docking were applied to validate the binding ability of RUT components to tumor necrosis factor α (TNF-α) targets. RESULTS: RUT reduced the levels of infiltrating neutrophils and monocytes and decreased the levels of the proinflammatory cytokines interleukin 1β (IL-1β) and interleukin 6 (IL-6, all P<0.01). In vitro, RUT reduced the production of IL-1β, IL-6 and TNF-α. In addition, RT-PCR revealed the inhibitory effects of RUT on the mRNA levels of IL-1β, IL-6, cyclooxygenase-2 and TNF-α (P<0.05 or P<0.01). Mechanistically, RUT markedly reduced protein expressions of tumor necrosis factor receptor (TNFR), phospho-mitogen-activated protein kinase (p-MAPK), phospho-extracellular signal-regulated kinase, phospho-c-Jun N-terminal kinase, phospho-NF-κB, phospho-kinase α/β, NOD-like receptor thermal protein domain associated protein 3 (NLRPS), cleaved-cysteinyl aspartate specific proteinase-1 and cleaved-gasdermin D in macrophages (P<0.05 or P<0.01). Molecularly, SPR revealed that RUT bound to TNF-α with a calculated equilibrium dissociation constant of 31.7 µmol/L. Molecular docking further confirmed that RUT could interact directly with the TNF-α protein via hydrogen bonding, van der Waals interactions, and carbon-hydrogen bonding. CONCLUSION RUT alleviated MSU-induced peritonitis and inhibited the TNFR1-MAPK/NF-κB and NLRP3 inflammasome signaling pathway to attenuate gouty inflammation induced by LPS/MSU in THP-1 macrophages, suggesting that RUT could be a potential therapeutic candidate for gout.

Objective Understanding the population structure of mosquitoes in the drainage system of Minhang District,Shanghai,and exploring the physical prevention and control technology of mosquito traps with a Vazor mosquito repellent film in the drainage system.Methods A 500 mL water spoon was used to assist in visual inspection to investigate the breeding status of mosquito larvae in the drainage system.A carbon dioxide mosquito trap method was used to monitor adult mosquitoes around the ground drainage system,and the artificial hour method was used to monitor adult mosquitoes around the underground drainage system.Mosquito-repellent film was applied at a rate of 1 mL/m2 to the drainage system where mosquito larvae or pupae are found,and the breeding situation was observed and recorded.Results The positivity rate of mosquitoes breeding in the ground drainage system was 50%.The mosquito larvae in the drainage channels were primarily Aedes albopictus,whereas Ae.albopictus were primarily noted in the sewage wells.The proportions of Ae.albopictus and Culex pipiens pallens in the rainwater wells were similar,and the dominant mosquito species around the surface drainage system was Ae.Albopictus.The positive rate of mosquito breeding in the underground drainage system was 47%,with the dominant mosquito species being Cx.pipiens pallens(58.39%)followed by Ae.albopictus(41.6%).The dominant adult mosquito species around the drainage system were Cx.pipiens pallens(83%)followed by Ae.albopictus(11%).In terms of the effectiveness of mosquito-repellent water film,the mosquito breeding rates of the ground and underground drainage systems using mosquito-repellent water film decreased to 2.78%and 5%after 1 week of use,respectively,and then rebounded after the 3rd week.After a supplementary dose during the 5th week,the breeding rates returned to normal.No statistically significant differences were observed in the effect compared with the standard control group using 1%bisulfite granules;however,a statistically significant difference was noted compared with the blank control group without special treatment.Conclusions In the drainage system of Minhang District,Shanghai,mosquito breeding is severe,and variations exist in the dominant mosquito species in different environmental drainage facilities.The simultaneous use of mosquito-repellent films can effectively control mosquito breeding in drainage systems.

Objective To investigate the expression changes of T-cell exhaustion-related genes in multiple myeloma(MM)and their potential causal relationships.Methods A bidirectional summary-level Mendelian randomization(MR)analysis was used to explore the causal relationship between T-cell exhaustion and MM.The eQTL data and genome-wide association study(GWAS)were used to summarize data,and corresponding single nucleotide polymorphisms(SNPs)were extracted as instru-mental variables.Four methods,namely inverse variance weighted(IVW)method,MR Egger,weighted median,and weighted mode were used to assess the reliability of the causal relationship.The robustness of the results was validated using Cochran's Q heterogeneity test and pleiotropy test.In cel-lular models,RNA interference was used to silence key target genes,and phenotypic changes such as myeloma cell viability,colony-forming ability,and apoptosis were observed to experimentally confirm the causal effects revealed by MR.Results The genes PRDM1,ENTPD1,PTPN11,and HLA-B were involved in the T-cell exhaustion process in MM.The presence of the PRDM1 gene(OR=0.998 5,95％CI,0.997 1 to 0.999 8,P=0.024 6)may reduce the risk of MM,whereas ENTPD1(OR=1.000 4,95％CI,1.000 1 to 1.000 7,P=0.015 8),HLA-B(OR=1.000 4,95％CI,1.000 1 to 1.000 8,P=0.012 4),and PTPN11(OR=1.002 5,95％CI,1.001 0 to 1.003 9,P=0.001 2)were associated with an increased risk of MM.Real-time quantitative polymerase chain reaction showed overexpression of PTPN11 in MM cell lines and patients' samples.By assessing cell viabili-ty,colony formation and detecting apoptosis,it was found that inhibiting PTPN11 promoted apopto-sis in MM cell lines.Conclusion A causal relationship exists between T-cell exhaustion and MM.Targeted interventions against specific T-cell exhaustion-related genes may help reduce the incidence of MM.

This paper aims to study the effect of p-cymene on mice with deficiency-cold syndrome induced by hydrocortisone and deficiency-heat syndrome induced by dexamethasone and explore the medicinal properties and mechanism of p-cymene with mild and warm nature based on the dominant characteristics of the two-way applicable conditions of mild drugs. A total of 80 KM mice were randomly divided into blank group, deficiency-cold syndrome model group, deficiency-cold syndrome + ginseng group, and deficiency-cold syndrome + low-dose and high-dose p-cymene groups, as well as blank group, deficiency-heat syndrome model group, deficiency-heat syndrome + American ginseng group, and deficiency-heat syndrome + low-dose and high-dose p-cymene groups. Hydrocortisone and dexamethasone solution were intragastrically administered for 14 consecutive days to prepare deficiency-cold syndrome and deficiency-heat syndrome models. Except for the blank group and the model group intragastrically administered with normal saline, the other groups were intragastrically administrated with drugs for 14 days. The levels of cyclic adenosine monophosphate(cAMP), cyclic guanosine monophosphate(cGMP), triiodothyronine(T3), thyroxine(T4), total cholesterol(TC), triglyceride(TG), immunoglobin G(IgG), and immunoglobin M(IgM) in serum, as well as the activity of Na~+-K~+-ATPase in liver tissue were detected. The expression of transient receptor potential melastatin 8(TRPM8), transient receptor potential vanilloid 1(TRPV1), and uncoupling protein 1(UCP1) in brown adipose tissue of deficiency-cold syndrome model after intervention with p-cymene was studied. The results showed that p-cymene could effectively improve the levels of cAMP, cAMP/cGMP, TC, IgM, and IgG in serum and the activity of Na~+-K~+-ATPase in liver tissue of mice with deficiency-cold syndrome and reduce the content of cGMP. The effects on T3, T4, and TG were not statistically significant. At the same time, p-cymene could reduce the levels of cAMP, cAMP/cGMP, and T4 in serum and the activity of Na~+-K~+-ATPase in liver tissue of mice with deficiency-cold syndrome and increase the levels of cGMP, IgM, and IgG, and it had no effect on T3, TC, and TG. In addition, p-cymene could up-regulate the expression of TRPV1 and UCP1 in brown fat of mice with deficiency-cold syndrome and down-regulate the expression of TRPM8. In summary, p-cymene could significantly regulate the syndrome indexes of mice with deficiency-cold syndrome, and some indexes of mice with deficiency-heat syndrome could be improved, but the effects on lipid metabolism and energy metabolism indexes were not obvious, indicating that the regulation effect of p-cymene on deficiency-cold syndrome model was more prominent and that the medicinal properties of p-cymene were mild and warm. The regulation of TRPV1/TRPM8/UCP1 channel expression may be the molecular biological mechanism of p-cymene with mild and warm nature affecting the energy metabolism of the body.
