Objective To explore characteristics of clinical parameters and cytokines in patients with drug-induced liver injury(DILI)caused by different drugs and their correlation with clinical indicators. Method The study was conducted on patients who were up to Review of Uncertainties in Confidence Assessment for Medical Tests(RUCAM)scoring criteria and clinically diagnosed with DILI.Based on Chinese herbal medicine,cardiovascular drugs,non-steroidal anti-inflammatory drugs(NSAIDs),anti-infective drugs,and other drugs,patients were divided into five groups.Cytokines were measured by Luminex technology.Baseline characteristics of clinical biochemical indicators and cytokines in DILI patients and their correlation were analyzed. Results 73 patients were enrolled.Age among five groups was statistically different(P=0.032).Alanine aminotransferase(ALT)(P=0.033)and aspartate aminotransferase(AST)(P=0.007)in NSAIDs group were higher than those in chinese herbal medicine group.Interleukin-6(IL-6)and tumor necrosis factor alpha(TNF-α)in patients with Chinese herbal medicine(IL-6:P<0.001;TNF-α:P<0.001)and cardiovascular medicine(IL-6:P=0.020;TNF-α:P=0.001)were lower than those in NSAIDs group.There was a positive correlation between ALT(r=0.697,P=0.025),AST(r=0.721,P=0.019),and IL-6 in NSAIDs group. Conclusion Older age may be more prone to DILI.Patients with NSAIDs have more severe liver damage in early stages of DILI,TNF-α and IL-6 may partake the inflammatory process of DILI.

The adulteration and counterfeiting of herbal ingredients in medicinal and food homology (MFH) have a serious impact on the quality of herbal materials, thereby endangering human health. Compared to pharmaceutical drugs, health products derived from traditional Chinese medicine (TCM) are more easily accessible and closely integrated into consumers' daily life. However, the authentication of the authenticity of TCM ingredients in MFH has not received sufficient attention. The lack of clear standards emphasizes the necessity of conducting systematic research in this area. This study utilized DNA barcoding technology, combining ITS2, psbA-trnH, matK as universal barcode sequences, and DX, HH, JYH as specific barcode sequences, to identify the authenticity of commercial medicinal and food homology scented herbal teas. The aim was to investigate the authenticity of scented herbal tea products circulating in the market. The research results revealed that among 180 scented herbal tea samples, DNA barcodes were successfully obtained from 164 samples, while the remaining samples either lacked the target components or suffered severe DNA degradation, resulting in failed amplification. Combined with morphological identification studies, it was found that out of the 180 samples, 141 were authentic, accounting for 78.33% of the total samples, while 31 samples showed adulteration and 8 samples lacked the target components, accounting for 21.67% of the total samples. Additionally, water testing revealed that 5 samples of Carthamus tinctorius herbal tea exhibited the phenomenon of weight adulteration. This study exposed the presence of adulteration and weight adulteration in scented herbal tea products, highlighting the need for regulatory authorities to expedite the establishment of quality standards in scented herbal tea industry. These findings provide valuable insights for the rapid development of the scented herbal tea industry.

Objective To investigate the prevalence of tension-type headache(TTH)in children and adolescents aged 0-19 years globally in 1990-2021,and to provide a basis for the prevention and treatment of TTH.Methods Based on the Global Burden of Disease Study data,the age-standardized prevalence distribution of TTH and its changing trend were analyzed among the children and adolescents aged 0-19 years,with different sexes,age groups,sociodemographic index(SDI)regions and countries/territories.Results The age-standardized prevalence rate(ASPR)of TTH in children and adolescents aged 0-19 globally in 2021 was 17 339.89/100 000,which was increased by 1.73%since 1990.The ASPR in females was slightly higher than that in males(1990:17 707.65/100 000 vs 16 403.78/100 000;2021:17 946.29/100 000 vs 16 763.09/100 000).The ASPR in adolescence was significantly higher than that in school-aged and preschool periods(1990:27 672.04/100 000 vs 10 134.16/100 000;2021:28 239.04/100 000 vs 10 059.39/100 000).Regions with high SDI exhibited a higher ASPR than the other regions,with significant differences in prevalence rates across different countries.From 1990 to 2021,there was a slight increase in global ASPR,with an average annual percentage change(AAPC)of 0.06%.Females experienced a smaller increase than males based on AAPC(0.04%vs 0.07%).There was reduction in ASPR in preschool and school-aged groups,with an AAPC of-0.02%,while there was a significant increase in ASPR in adolescence,with an AAPC of 0.07%.ASPR decreased in regions with low-middle and low levels of SDI,with an AAPC of-0.02%and-0.04%,respectively,while it increased in regions with middle SDI,with an AAPC of 0.24%.Conclusions There is a consistent increase in the ASPR of TTH in children and adolescents aged 0-19 years globally,with significant differences across sexes,age groups,SDI regions and countries/territories.

Protein methylation is a common post-translational modification in organisms.For a long time,research on protein methylation mainly focused on arginine and lysine,and there were few reports on histidine methylation.However,recent studies have emphasized that histidine methylation is also a widespread and highly conserved modification,occurring at the Nπ and Nτ sites of the histidine imidazole ring,catalyzed by specific protein histidine methyltransferases(PHMTs).Here,we review the history and significant advances in histidine methylation in recent years,particularly highlighting several known histidine methyltransferases.These methyltransferases,through specific molecular mechanisms,are re-sponsible for precise methylation modifications on histidine residues,playing crucial roles in processes such as cell movement,tumor cell proliferation,and protein translation.Additionally,this article discus-ses the research methods for histidine methylation,especially the application of mass spectrometry,which plays a vital role in advancing histidine methylation research.Although the veil of histidine methylation is gradually being lifted,a complete understanding of this modification and its functional mechanisms still poses challenges.Therefore,this article also presents new insights into the current dilemmas in histidine methylation research and future research priorities,hoping to uncover more secrets of histidine methyla-tion in the future.This could expand the protein methylation modification network and provide new per-spectives and strategies for elucidating disease mechanisms and developing new therapeutic approaches.

Aim To investigate the effects of puerarin on the proliferation,migration,and apoptosis of glio-blastoma cells and the underlying mechanisms.Meth-ods Differentially expressed genes associated with gli-oma and mitochondrial disease were analyzed using the GEO database.Cytotoxicity was detected by CCK-8 as-say.Cell migration was detected by the scratch wound healing assay and Transwell assay.Cell proliferation was assessed by EdU assay.Apoptosis level was meas-ured by TUNEL assay.Mitochondrial membrane poten-tial was detected by Mito-Tracker assay.ATP contents were detected using the ATP kit.The protein expres-sion levels were detected by Western blot.Antitumor efficacy of puerarin was analyzed using subcutaneous xenograft.Results There were 178 genes co-related differentially expressed genes in glioma and mitochon-drial disease.Core genes of co-related differentially ex-pressed genes were screened by GO and KEGG enrich-ment analyses,and the interaction networks.Among them,ubiquitin C(UBC)level was highly expressed in tissues of glioma patients.Puerarin could bind to UBC and reduce UBC expression at the animal and cell levels.Puerarin treatment inhibited the growth of glio-ma and decreased cell proliferation,migration and pro-moted cell apoptosis signals.Meantime,puerarin treat-ment also reduced mitochondrial membrane potentials and ATP contents,and down-regulated the levels of UBC related proteins.Conclusion Puerarin inhibits the proliferation,migration and promotes apoptosis of glioma cells.The mechanism of induction of mitochon-drial dysfunction is involved.

Refractory prolactinoma is the most common pituitary neuroendocrine tumor.Dopamine receptor agonists(DA)are the primary choice for drug treatment.Most patients with prolactinomas respond well to DA.However,a minority of prolactinomas patients still show resistance to DA.Although drug-resistant and refractory prolactinomas are rare in clinical practice,their treatment is extremely challenging.Even a combination of drug therapy,multiple surgeries,and radiotherapy may not yield satisfactory outcomes.Therefore,standardizing the diagnosis and treatment process and pathway for refractory prolactionmas and exploring more effective multidisciplinary collaborative treatment strategies are urgent problems to be solved.In the clinical management of refractory prolactinomas,it is often necessary to consider the patient's condition comprehensively,replace other types of DA,or consider surgery,radiotherapy,and immunotherapy,which requires multidisciplinary diagnosis and treatment.This review synthesizes the latest literature at home and abroad to systematically discuss the latest advances in drug therapy,surgery,and radiotherapy treatments for refractory prolactionmas,aiming to provide new ideas for basic research,clinical diagnosis and treatment.

Objective:To evaluate the diagnostic value of hematological parameters for PCa with prostate-specific antigen(PSA)of 4-10 μg/L and construct a risk-stratification model with these parameters.Methods:We retrospectively analyzed the da-ta on the males undergoing the initial prostatic biopsy in the Affiliated Hospital of Xuzhou Medical University with PSA of 4-10 μg/L from March 2010 to April 2021.According to the results of biopsy,we classified the patients into a PCa and a non-PCa group,and compared the hematological parameters between the two groups.We performed univariate and multivariate logistic regression analyses,identified the independent risk factors for PCa,constructed a risk-stratification model for the prediction of PCa and evaluated its effi-ciency.Results:A total of 415 cases were included in this study,107(25.8％)in the PCa and 308(74.2％)in the non-PCa group.Compared with the non-PCa males,the PCa patients showed a significantly older age,higher ratios of neutrophil to lymphocyte and platelet to lymphocyte,systemic immune-inflammation index(SII),red blood cell distribution width and cystatin C(CysC)level(all P＜0.05),but lower red blood cell count and hemoglobin and free/total PSA(f/tPSA)levels(all P＜0.05).Multivariate logis-tic regression analysis indicated that age,f/tPSA,SII and CysC were independent risk factors for the prediction of PCa(all P＜0.05).Five prediction models were constructed based on the above risk factors,and the area under the ROC curve(AUC)of the four-parameter(age+f/tPSA+SII+CysC)model was 0.745(95％CI:0.694-0.796),significantly higher than those of the other mod-els(P＜0.05).A risk-stratification model(low-,intermediate-,and high-risk)was also constructed based on the total nomogram scores,which showed a comparable performance to that of the Prostate Imaging Reporting and Data System(PI-RADS)for the predic-tion of PCa(AUC:0.727[95％CI:0.650-0.804]vs 0.734[95％CI:0.658-0.811]).However,the prediction rate by the risk-stratification model was evidently higher in the low-risk males than in those with low PI-RADS scores(1-2)(39.4％vs 22.2％).Conclusion:SII and CysC are independent risk factors for the prediction of PCa in patients with gray-zone PSA levels.The risk-stratification model based on age,SII,CysC and f/tPSA is comparable to PI-RADS in the diagnostic efficiency of PCa,with an even higher prediction rate in low-risk patients than in those with low PI-RADS scores,and contributive to precision screening and reduction of excessive biopsies in the diagnosis of PCa with gray-zone PSA.

Objective:To evaluate the efficacy and safety of 532-nm picosecond laser in the treatment of early-stage facial seborrheic keratosis.Methods:A total of 95 patients with early-stage facial seborrheic keratosis were prospectively enrolled from the Department of Dermatology, General Hospital of Ningxia Medical University between December 2020 and September 2022. All the patients received a session of 532-nm picosecond laser treatment, and were followed up for 6 months. A 4-point scale was used to evaluate the overall improvement of skin lesions for assessing the clinical efficacy. A VISIA skin detector was used to quantitatively determine the characteristic counts, absolute scores, and percentiles of brown spots before and after treatment, and the paired sample t-test was used to compare the quantitative indicators of brown spots before and after treatment. The patients′ pain grades were evaluated, and adverse reactions were recorded. Results:All the 95 patients with early-stage facial seborrheic keratosis received a session of 532-nm picosecond laser treatment, and completed a 6-month follow-up. All the patients achieved over 25% regression of skin lesions in the treatment area, of whom 10 received mild improvement, 17 received favorable improvement, and 68 received marked improvement, with the response rate being 89.47% (85/95). The examination with the VISIA skin detector showed that the characteristic counts (195.19 ± 51.06) and absolute scores (28.80 ± 6.20 points) of brown spots significantly decreased, while the percentiles of brown spots (38.48% ± 10.80%) significantly increased at 6 months after treatment compared with the corresponding baseline indicators (211.48 ± 50.94, 35.16 ± 6.84 points, 30.61% ± 10.27%, t = 12.73, 16.90, -15.73, respectively, all P < 0.001). All the patients experienced varying degrees of pain during the treatment, with the pain scores being 2 - 6 (3.64 ± 1.67) points, but all of them could tolerate the pain and completed the treatment. Temporary postinflammatory hyperpigmentation and hypopigmentation occurred in 9 (9.47%) and 4 (4.21%) patients respectively, and the skin color restored to normal during the 6-month follow-up. Conclusion:The 532-nm picosecond laser was safe and effective for the treatment of early-stage facial seborrheic keratosis.

OBJECTIVE: To screen the prognostic biomarkers of metabolic genes in patients with multiple myeloma (MM), and construct a prognostic model of metabolic genes. METHODS: The histological database related to MM patients was searched. Data from MM patients and healthy controls with complete clinical information were selected for analysis.The second generation sequencing data and clinical information of bone marrow tissue of MM patients and healthy controls were collected from human protein atlas (HPA) and multiple myeloma research foundation (MMRF) databases. The gene set of metabolism-related pathways was extracted from Molecular Signatures Database (MSigDB) by Perl language. The biomarkers related to MM metabolism were screened by difference analysis, univariate Cox risk regression analysis and LASSO regression analysis, and the risk prognostic model and Nomogram were constructed. Risk curve and survival curve were used to verify the grouping effect of the model. Gene set enrichment analysis (GSEA) was used to study the difference of biological pathway enrichment between high risk group and low risk group. Multivariate Cox risk regression analysis was used to verify the independent prognostic ability of risk score. RESULTS: A total of 8 mRNAs which were significantly related to the survival and prognosis of MM patients were obtained (P<0.01). As molecular markers, MM patients could be divided into high-risk group and low-risk group. Survival curve and risk curve showed that the overall survival time of patients in the low-risk group was significantly better than that in the high risk group (P<0.001). GSEA results showed that signal pathways related to basic metabolism, cell differentiation and cell cycle were significantly enriched in the high-risk group, while ribosome and N polysaccharide biosynthesis signaling pathway were more enriched in the low-risk group. Multivariate Cox regression analysis showed that the risk score composed of the eight metabolism-related genes could be used as an independent risk factor for the prognosis of MM patients, and receiver operating characteristic curve (ROC) showed that the molecular signatures of metabolism-related genes had the best predictive effect. CONCLUSION Metabolism-related pathways play an important role in the pathogenesis and prognosis of patients with MM. The clinical significance of the risk assessment model for patients with MM constructed based on eight metabolism-related core genes needs to be confirmed by further clinical studies.
