MethodsThe rat's trigeminal neuralgia model was constructed by infraorbital injection of Talci Pulvis， and the rats were randomly divided into the normal group， model group， carbamazepine group （60 mg·kg^-1）， Cranial Painkiller granules group （2.70 g·kg^-1）， and low， medium， and high dosage groups of Cranial Painkiller pills' extract powder （1.35， 2.70， 5.40 g·kg^-1） according to the basal mechanical pain thresholds， and there were 10 rats in each group. The drug was administered by gavage to each group 2 h after modeling， and distilled water was given by gavage to the normal and model groups under the same conditions once a day for 10 d. Von Frey brushes were used to measure mechanical pain thresholds in rats. Hematoxylin-eosin （HE） staining was used to detect pathological changes in the trigeminal ganglion， and enzyme-linked immunosorbent assay （ELISA） was used to detect the inflammatory factors interleukin-1 （IL-1）， interleukin-6 （IL-6）， interleukin-8 （IL-8）， and tumor necrosis factor-α （TNF-α） levels in rat serum， as well as neuropeptide substance P （SP） and β-endorphin （β-EP） levels in rat brain tissue. Western blot technique was used to detect the levels of NLRP3， ASC， Caspase-1， and OTULIN proteins in rat brain tissue. ResultsCompared with the normal group， the pain threshold of rats in the model group showed a continuous significant decrease （P<0.01）. The pathological damage of brain tissue was significant （P<0.01）， and the inflammatory levels of IL-1， IL-6， IL-8， and TNF-α in serum were significantly elevated （P<0.01）. The level of the SP in the brain tissue was significantly elevated （P<0.01）， and the level of β-EP was significantly reduced （P<0.01）， while the level of OTULIN was significantly reduced， and NLRP3， ASC， and Caspase-1 protein levels were significantly elevated （P<0.01）. After administration of the drug， compared with the model group， the pain threshold of each dose group of the Cranial Painkiller pills' extract powder and the Cranial Painkiller granules group significantly increased （P<0.01）. The inflammatory levels of IL-1， IL-6， IL-8， and TNF-α and SP levels significantly decreased （P<0.01）， and the β-EP levels were significantly elevated （P<0.01）， while the levels of OTULIN protein were significantly elevated （P<0.05， P<0.01）， and the levels of NLRP3， ASC proteins were decreased （P<0.01）in high dose Cranial Painkiller pills' extract powder. Meanwhile， compared with those in the model group， the trigeminal ganglion lesions of rats in the Cranial Painkiller pills' extract powder and Cranial Painkiller granules groups showed different degrees of improvement （P<0.05， P<0.01）. ConclusionThe Cranial Painkiller pills' extract powder has significant therapeutic effects on the rat model of trigeminal neuralgia induced by infraorbital injection of Talci Pulvis， and its mechanism is related to the improvement of OTULIN-regulated neuroinflammation.

The median risk values of formaldehyde and benzene for carcinogenesis in hair salons and beauty salons were both greater than 10^-6, with maximum values higher than 10^-4. The median chronic non-carcinogenic risk value of formaldehyde in the indoor air of hair salons and beauty salons was greater than 1. The median chronic non-carcinogenic risk values for benzene and ammonia were both less than 1, but the maximum risk value was greater than 1. Conclusion Benzene and formaldehyde in the indoor air of hair salons and beauty salons in Jinan City have carcinogenic and non-carcinogenic risks, while ammonia has non-carcinogenic risks, which should be paid attention to.

Aim To study the mechanism of adipose mesenchymal stem cell exosomes(ASC-exo)inhibition of fluorescein isothiocyanate(FITC)-induced atopic dermatitis(AD).Methods The mouse age,extrac-tion method,and the concentration of a solution of typeⅠ collagen enzyme and other conditions were compared to study the effects on the morphology and quantity of adipose mesenchymal stem cells(ASCs)after extrac-ted.FITC-induced mouse model in vivo was estab-lished and different doses of ASC-exo were given to measure ear thickness,ear weight and ear scratching times of mice.HE staining was used to observe the pathological changes of ear tissue of mice.The non-toxicity of ASC-exo was detected.IgE,IL-5,IL-13 and other cytokines were detected by ELISA.The gene ex-pressions of TSLP,IL-33,occludin,Claudin-1(CLDN-1)and E-cadherin were detected by RT-qPCR.The protein expression was detected by immunohistochemis-try.Results An efficient method for extracting ASCs was established.Compared with the blank group,mice in the model group showed obvious AD symptoms.Compared with the model group,ASC-exo administra-tion group significantly reduced the number of ear scratches,epidermal thickening,inflammatory cell infil-tration and the secretion of Th2 cytokines IL-5 and IL-13.Meanwhile,ASC-exo administration group signifi-cantly increased the expression of structural proteins CLDN-1 and occludin in epithelial cells and decreased the expression of TSLP and IL-33.Conclusions ASC-exo can significantly improve Th2 skin inflamma-tion in AD mice,and its mechanism may be through in-creasing the expression of tight junction proteins and adhesion link protein in epithelial cells,repairing the skin barrier,and inhibiting the key promoters of allergy TSLP and IL-33.

Objective To develop a prognostic risk model for anoikis-related genes(ANRs)in bladder cancer,calculate risk scores,and analyze the relationship between bladder cancer patients with high and low risk scores and the tumor microenvironment.Methods Prognosis-related ANRs and clinically independent risk factors were screened by public database information and Cox regression analysis.Prognostic risk modeling was performed by least absolute shrinkage and selection operator(LASSO)analysis and column-line diagrams.Prognostic risk model accuracy was validated by kaplan-meier survival analysis and area under receiver operating characteristic curve(ROC)curve(AUC).The relationship between risk score and tumor microenvironment was explored by CIBERSORT(https://cibersortx.stanford.edu/)and single sample gene set enrichment analysis(ssGSEA).Results The prognostically relevant ANRs were B-lymphoblastoma-2-associated promoter(BAD),cell cycle protein-dependent kinase inhibitor 3(CDKN3),and proliferating cell nuclear antigen(PCNA),and the clinically independent risk factors were gender,age,clinical stage(T,N),and risk score.The prognostic risk model was expressed as risk score=(0.155 2 × BAD expression)+(0.2286 × CDKN3 expression)+(0.0114×PCNA expression)and column line graph.The lower the risk score the better the prognosis of bladder cancer patients,the AUC of the survival curves for 1,3 and 5 years were 0.732,0.620 and 0.541,respectively,and the column line graphs of the 1-,3-and 5-year calibration curves almost corresponded diagonally,reflecting the accuracy of the model.The high and low risk groups of the prognostic risk model showed great differences in immune cell infiltration in the tumor microenvironment of bladder cancer.Conclusion The established prognostic risk model for bladder cancer loss of apoptosis-related genes is highly accurate and can better assess the prognosis of bladder cancer patients,and bladder cancer patients with high and low risk scores are closely related to the tumor microenvironment.

Objective:Invasive pulmonary mucormycosis(PM)is a rare but highly lethal opportunistic infection.COVID-19 associated mucormycosis(CAM)is difficult to diagnose,often leading to misdiagnosis or missed diagnosis,and has poor treatment outcomes.This study reports a case of successfully treated CAM and explores optimized diagnostic and therapeutic strategies.Methods:A retrospective analysis of the diagnosis and treatment process in a 50-year-old female patient with COVID-19 associated with diabetic ketoacidosis(DKA)and invasive pulmonary mucormycosis was conducted.Combined with a literature review,the therapeutic efficacy of local bronchoscopic instillation in conjunction with systemic treatment using liposomal Amphotericin B(L-AmB)was specifically evaluated.Results:The patient was rapidly diagnosed with Rhizopus microsporus infection through metagenomic next-generation sequencing(mNGS).She subsequently received antifungal treatment with intravenous L-AmB combined with local bronchoscopic instillation.After treatment,the patient was significantly improved,with imaging studies showing gradual absorption of the lesions.Follow-up at six months revealed no recurrence.A literature review suggests that early diagnosis and multimodal therapy are key to improving survival rates in patients with CAM.Conclusion:mNGS can significantly improve the early diagnosis rate of CAM.The combination of local and systemic treatment with L-AmB is valuable in improving prognosis.Early diagnosis,multimodal antifungal therapy,and individualized management are key to increasing the survival rate of patients with CAM.

Objective:To investigate the effects of wheat-grain moxibustion at the Guanyuan point on testosterone(T)synthe-sis and the hypothalamic-pituitary-gonadal(HPG)axis in naturally aged mice.Methods:We fed 40 twelve-month-old SPF male C57BL/6J mice with a normal diet for 3 months,randomized them into a moxibustion and an aged group of an equal number,and se-lected 7 four-month-old ones as young controls.We treated the animals of the moxibustion group by wheat-grain moxibustion at the Guanyuan point,once 5 moxibustion sticks,qd,5 times a week,and fed those of the aged group normally,all for 12 weeks.After treatment,we obtained the testicular index of the mice,observed the histomorphology of the testis tissue by HE staining,measured the contents of T in the testis,gonadotropin-releasing hormone(GnRH)in the hypothalamus and total T(tT),free T(fT),luteinizing hormone(LH)and follicle-stimulating hormone(FSH)in the serum by ELISA,and determined the expressions of silence information regulator-1(SIRT1),P53,glutathione peroxidase(GPX4)and cholesterol side-chain?cleavage enzym e(CYP11A1)in the testis by Western blot.Results:Compared with the young controls,the mice in the aged group showed obviously losing and dull hair,energy declination,loose structure of the spermatogenic tubule with different degrees of cell loss and rupture,reduced testicular index,and ev-ident aging phenotype.In comparison with the aged mice,the animals of the moxibustion group were fairly energetic and exhibited dis-tinct structure of the spermatogenic tubules,orderly arranged and highly differentiated cells at all levels,significantly increased T lev-el,up-regulated expressions of SIRT1,GPX4 and CYP11 A1,and down-regulated expression of P53 in testis tissue,and elevated levels of GnRH,FSH,LH,tT and fT in the HPG axis.Conclusion:Wheat-grain moxibustion at the Guanyuan point protects testosterone synthesis in the testis tissue of naturally aged mice,promotes negative feedback regulation of the HPG axis,and improves low testoster-one.
