OBJECTIVE To evaluate the quality of Euscaphis japonica from different habitats. METHODS The relative correction factors of gallic acid， protocatechuic acid， ellagic acid， isoquercitrin， astragalin and apigenin were calculated with quercetin as the internal reference； the relative correction factors of euscaphic acid， oleanolic acid， stigmasterol and β-sitosterol were also calculated with ursolic acid as the internal reference. The contents of 12 components in 18 batches of samples were calculated by QAMS method and were compared with external standard method. At the same time， the contents of water-soluble extract， alcohol-soluble extract， total ash and acid-insoluble ash were detected. The quality of E. japonica was evaluated by principal component analysis （PCA）， orthogonal partial least squares-discriminant analysis （OPLS-DA）， and weighted technique for order preference by similarity to ideal solution （TOPSIS） method. RESULTS There was no significant difference between the results of QAMS method and external standard method for the 12 components in the 18 batches of samples. However， notable content variations were observed among different batches of samples. The results of PCA and OPLS-DA showed that S1-S7， S8- S12， and S13-S18 were clustered into one category respectively. Seven key characteristic components variable importance in projection values ＞1， euscaphic acid， ursolic acid， protocatechuic acid， apigenin， β-sitosterol， isoquercitrin， and oleanolic acid， respectively. The analysis results of the weighted TOPSIS method revealed that the relative closeness for evaluating the quality of 18 batches of samples ranged from 0.283 5 to 0.644 1， with the samples of E. japonica from Fengjie， Chongqing， demonstrating the highest quality. CONCLUSIONS The established method is accurate and feasible， which can be used for the quality evaluation of E. japonica combined with chemometrics and weighted TOPSIS model.

Astrocytes in the spinal dorsal horn (SDH) exhibit diverse reactive phenotypes under neuropathic conditions, yet the mechanisms driving this diversity and its implications in chronic pain remain unclear. Here, we report that spared nerve injury (SNI) induces marked upregulation of both complement component 3 (C3⁺, A1-like) and S100 calcium-binding protein A10 (S100A10⁺, A2-like) astrocyte subpopulations in the SDH, with elevated microglial cytokines including interleukin-1α, tumor necrosis factor-α, and complement component 1q. Transcriptomic, immunohistochemical, and Western blot analyses reveal co-activation of multiple reactive astrocyte states over a unidirectional shift toward an A1-like phenotype. Fibroblast growth factor 8 (FGF8), a neuroprotective factor via FGFR3, mitigated microglia-induced C3⁺ astrocyte reactivity in vitro and suppressed spinal C3 expression and mechanical allodynia following intrathecal administration in SNI mice. These findings reveal a microglia-astrocyte signaling axis that promotes A1 reactivity and position FGF8 as a promising therapeutic candidate for neuropathic pain by modulating astrocyte heterogeneity.

ObjectiveTo investigate the effect and mechanism of Zhenwutang on renal oxidative damage in the mouse model of diabetic kidney disease with the syndrome of spleen-kidney Yang deficiency via the nuclear factor erythroid 2-related factor-2 （Nrf2）/heme oxygenase-1 （HO-1）/glutathione peroxidase 4 （GPX4） signaling pathway. MethodTwenty-five 7-week-old SPF-grade male db/m mice and 95 7-week-old SPF-grade male db/db mice were adaptively fed for a week. A blank group was set with the db/m mice without treatment， and the other mice were administrated with Rhei Radix et Rhizoma decoction and hydrocortisone for the modeling of diabetic kidney disease with the syndrome of spleen-kidney Yang deficiency. The modeled mice were randomized into the model， irbesartan （25 mg·kg^-1）， and high-， medium-， low-dose （33.8， 16.9， 8.45 g·kg^-1） Zhenwutang groups （n=15） and administrated with corresponding drugs for 8 weeks. The survival status of mice was observed， and the traditional Chinese medicine （TCM） syndrome score was recorded. The indicators related to spleen-kidney Yang deficiency， fasting blood glucose （FBG）， and renal function indicators were determined. Hematoxylin-eosin staining was employed to observe the histopathological changes of the renal tissue in each group. Biochemical kits were used to determine the oxidative stress-related indicators in the renal tissue. Real-time polymerase chain reaction and Western blotting were employed to determine the mRNA and protein levels， respectively， of Nrf2， HO-1， glutamate-cysteine ligase catalytic subunit （GCLC）， and GPX4 in the renal tissue of mice in each group. ResultCompared with the blank group， the modeling increased the TCM syndrome score （P<0.05）， elevated the estradiol （E₂） and FBG levels （P<0.05）， lowered the testosterone （T）， triiodothyronine （T3）， and tetraiodothyronine （T4） levels （P<0.05）， and weakened the renal function （P<0.05）. In addition， the modeling led to glomerular hypertrophy and glomerular mesangial and basal thickening， decreased the catalase （CAT） activity， total antioxidant capacity （T-AOC）， and glutathione （GSH） content （P<0.05）， increased the malondialdehyde （MDA） content （P<0.05）， and down-regulated the mRNA and protein levels of Nrf2， HO-1， GCLC， and GPX4 in the renal tissue （P<0.05）. Compared with the model group， high and medium doses of Zhenwutang decreased the TCM syndrome score and E₂ content （P<0.05）， increased the T， T3， and T4 content （P<0.05）， improved the renal function （P<0.05）， alleviated the pathological changes in the renal tissue， increased CAT， T-AOC， and GSH （P<0.05）， reduced MDA （P<0.05）， and up-regulated the mRNA and protein levels of Nrf2， HO-1， GCLC， and GPX4 in the renal tissue （P<0.05）. ConclusionZhenwutang can improve the general state and renal function and reduce the oxidative damage and pathological changes in the renal tissue of db/db mice with spleen-kidney Yang deficiency by regulating the Nrf2/HO-1/GPX4 signaling pathway.

Objective:To elucidate the primary elements pertaining to the perception of relapse risk and to in-vestigate the characteristics and alterations of perception of the risk of recurrence in patients with schizophrenia.Methods:By using the method of phenomenological study,semi-structured in-depth interviews were conducted among schizophrenic patients with first onset,first recurrence and multiple recurrences.Twenty-three 23 outpatient and inpatient cases that met the criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)were included,and all patients had PANSS scores below 60.The interview data were collated and analyzed according to Colaizzi analysis.Results:The perception of recurrence risk in patients with schizophrenia en-compassed 4 major themes and 11 sub-themes,namely susceptibility(limited overall understanding,transition from optimism to objectivity),detection of early warning symptoms(dynamic escalation,assistance from family mem-bers in identification),understanding risk factors(lack of understanding,the relationship between psychosocial fac-tors and relapse,dynamic understanding of medication-relapse relationship),and apprehension of the consequences of recurrence(care burden and financial constraints,impaired social functioning and maladjustment,impact on pub-lic safety,personal health risks).Conclusion:The content of risk perception of recurrence in patients with schizo-phrenia is relatively substantial.The overall level of risk perception of recurrence in patients with schizophrenia is low.

Objective To explore the influencing factors of medication experience in patients with schizophrenia based on benefit-risk perception.Methods Patients with stable schizophrenia who were hospitalized in 2 tertiary psychiatric hospitals in Heilongjiang Province from September to December 2023 were selected by convenience sampling method.A convergent mixed method was adopted.In quantitative study,data of 400 patients were collected by general situation questionnaire,Subjective Well-being Under Neuroleptic Treatment Scale,the Living with Medicines Questionnaire,Beliefs about Medication Questionnaire,Positive and Negative Syndrome Scale.Binary logistic regression analysis was used to explore the influencing factors of medication experience in patients with schizophrenia.15 patients with adverse medication experience in quantitative study were selected for qualitative study,and the interview data were sorted and analyzed according to the topic frame analysis method.Results Quantitative results:medication burden,medication beliefs,and psychiatric symptoms of patients with schizophrenia were influential factors of medication experience(P<0.05).Qualitative results:the medication experience of schizophrenia patients includes 4 themes,namely perceived necessity of medication,perceived benefit of medication,perceived risk of medication,and the need for multi-party cooperation to improve the medication experience.The results of quantitative and qualitative research are complementary in terms of perceived benefit,consistent in terms of perceived risk,and expansive in terms of perceived value.Conclusion Psychiatric nurses can reduce patients'perceived risk of medication,enhance the perceived benefit of medication,and then improve patients'adverse medication experience and promote mental rehabilitation.

We retrospectively analyzed the clinical data of seven patients (four men and three women) with primary hyperoxaluria (PH) type 1 (PH1) in the Department of Nephrology of Zhongda Hospital, Southeast University from January 2018 to October 2023. The mean age at disease onset was 32.1 (range: 26-42) years. The mean age at diagnosis was 40.6 (range: 28-51) years. All patients initially had kidney stones, and three patients were found to have renal insufficiency at the time of disease onset. Among them, two patients underwent hemodialysis immediately. Symptoms at the first visit included bone pain ( n=7), joint pain or deformity ( n=5), fatigue ( n=5), hypotension ( n=3), and subcutaneous nodules ( n=2). Four patients had a family history of PH. All patients had varying degrees of anemia (60-114 g/L), significant hypoalbuminemia (16.5-32.1 g/L), and hypercoagulable state (D-dimer: 2 230-12 781 μg/L). Seven patients received maintenance hemodialysis; their mean age was 37.7 (range: 26-50) years. The mean duration from disease onset to hemodialysis was 5.6 (range: 0-20) years. Five patients repeatedly experienced dialysis access dysfunction. Three patients underwent kidney transplantation before a diagnosis was made, and all transplanted kidneys lost function due to oxalate deposition. The mean follow-up duration was 14.43 (range: 4-38) months. Unfortunately, one patient died. All seven patients underwent computed tomography of the abdomen. All patients suffered skeletal abnormalities, bilateral nephrolithiasis, and nephrocalcinosis. Six patients carried AGXT gene mutations, including four compound heterozygous mutations and two pure homozygous mutations.The mutation sites included: c.823-824dup.AG (p.S275Rfs*38)(exon 8), c.815-816ins.GA (p.S275Rfs*38)(exon 8), c.595G>A (p.G199S) (exon 5), c.32C>G (p.P11R) (exon 1), and c.638C>T (p.A213V)(exon 6). According to the American College of Medical Genetics and Genomics guidelines, two loci were identified as likely pathogenic variants, seven were identified as pathogenic variants, and one locus was identified as having uncertain significance. In addition, patients 1 and 4 underwent skin biopsy, patient 2 underwent renal transplant biopsy, and patient 3 underwent bone marrow biopsy. Interestingly, significant oxalate deposition was found in the tissues. Therefore, PH1 is a rare autosomal recessive inherited disease. This study not only enhanced the understanding of the clinical characteristics of PH1 patients but also had great significance in early diagnosis and treatment of the disease.

The paper reports a rarely case of hemophagocytic syndrome complicated with thrombotic microangiopathy, first presented with fever of unknown origin. A 37-year-old female patient mainly presented with fever, hemolytic anemia, thrombocytopenia, and progressive decline in renal function. After infusion of fresh frozen plasma and high dose of glucocorticoid after double plasma exchange, the patient showed good prognosis, no further fever or hemolysis occurred, recovered platelet and renal function. After acute episode phase, kidney biopsy was performed and acute tubular necrosis was diagnosed. During the follow-up period, the disease did not recur, and the renal function was normal.

Purpose: Numerous barriers hinder individuals with mental illness from seeking medical assistance in rural regions, yet a comprehensive understanding of these challenges remains elusive. This metasynthesis aims to understand the barriers and facilitators in medical help-seeking among rural individuals with mental illness. Methods: We systematically searched seven databases [PubMed, CINAHL, Medline (OVID), PsycINFO (OVID), Cochrane, Embase, and ProQuest] in May 2023 and included the studies if they reported the barriers or/and facilitators to seek healthcare in rural patients with mental illness. We conducted hand search and citation search on Google Scholar for literature supplements. Thematic analysis was employed. Results: The study included 27 articles reporting on the barriers and facilitators to seeking medical help in this population from 2007 to 2023. We ultimately identified themes at three levels: navigating the terrain of vulnerability and empowerment (the individual with mental illness), navigating the terrain of external environment (the external environment) and connectivity within the healthcare ecosystem for mental health (the health service system). Conclusions We must design more effective strategies to improve mental healthcare access for rural patients, considering cultural nuances and health service utilization patterns. This requires a multi-level approach, tailored to the unique needs of diverse populations.

Spinal microglia and astrocytes are both involved in neuropathic and inflammatory pain, which may display sexual dimorphism. Here, we demonstrate that the sustained activation of spinal astrocytes and astrocyte-derived interleukin (IL)-17A promotes the progression of mouse bone cancer pain without sex differences. Chemogenetic or pharmacological inhibition of spinal astrocytes effectively ameliorates bone cancer-induced pain-like behaviors. In contrast, chemogenetic or optogenetic activation of spinal astrocytes triggers pain hypersensitivity, implying that bone cancer-induced astrocytic activation is involved in the development of bone cancer pain. IL-17A expression predominantly in spinal astrocytes, whereas its receptor IL-17 receptor A (IL-17RA) was mainly detected in neurons expressing VGLUT2 and PAX2, and a few in astrocytes expressing GFAP. Specific knockdown of IL-17A in spinal astrocytes blocked and delayed the development of bone cancer pain. IL-17A overexpression in spinal astrocytes directly induced thermal hyperalgesia and mechanical allodynia, which could be rescued by CaMKIIα inhibitor. Moreover, selective knockdown IL-17RA in spinal Vglut2 ⁺ or Vgat ⁺neurons, but not in astrocytes, significantly blocked the bone cancer-induced hyperalgesia. Together, our findings provide evidence for the crucial role of sex-independent astrocytic signaling in bone cancer pain. Targeting spinal astrocytes and IL-17A/IL-17RA-CaMKIIα signaling may offer new gender-inclusive therapeutic strategies for managing bone cancer pain.
