Neurological diseases have high morbidity and disability rates， posing a severe threat to human health. Cli nical manifestations include motor， sensory， cognitive and conscious disorders. Chaihu jia longgu muli decoction is derived from Treatise on Febrile Diseases ， with the effects of harmonizing Shaoyang， activating Yang and clearing heat， and tranquilizing the mind. This paper systematically reviews the research progress in clinical application and mechanism of Chaihu jia longgu muli decoction in the field of neurological diseases. It has been found that the decoction shows favorable efficacy in various neurological diseases such as insomnia， depression， epilepsy， vertigo， migraine and vascular dementia. The specific mechanisms are related to regulating neurotransmitter levels， repairing neuronal function， alleviating neuroinflammation， improving mitochondrial dysfunction and regulating intestinal flora. In the future， standardized prospective follow-up cohorts should be established， and core outcome indicators should be clearly defined to strengthen the evidence base. Furthermore， multidisciplinary research should be leveraged to expand the therapeutic value of Chaihu jia longgu muli decoction in the management of neurological diseases.

As a common medical condition， vertigo can be induced by multiple diseases in the modern medical system. Its incidence rate shows an upward trend with the increase in age. According to the theory of mutual interference between clear Qi and turbid Qi in Huangdi's Internal Classic （Huang Di Nei Jing）， this paper systematically analyzes the pathogenesis of vertigo and explores the mechanism and clinical application value of Xiao Chaihutang in the treatment of vertigo. It is believed that the mutual inference between clear Qi and turbid Qi leads to the failure of clear Yang to ascend， resulting in the lack of nourishment for the brain and the inability of turbid Yin to descend， which disturbs the clear orifices， thus causing vertigo. The core pathogenesis lies in the dysfunction of Qi movement， the disorder of body fluid distribution， and the imbalance between Yin and Yang. The compatibility of Xiao Chaihutang takes into account the methods of pungent medicinal materials opening and bitter medicinal materials descending， tonifying deficiency and purging excess， and regulating Qi movement. This prescription can regulate the pathological state of the mutual interference between clear Qi and turbid Qi from three aspects： regulating Qi movement throughout the body， harmonizing the distribution of body fluids， and coordinating Yin and Yang as well as the interior and exterior， thus preventing and treating vertigo. Modern research findings show that Xiao Chaihutang can improve hemodynamics to promote cerebral blood circulation and has anti-inflammation， immunomodulatory， and anti-tumor functions， which correspond to the therapeutic effects of Xiao Chaihutang under the theory of mutual interference between clear Qi and turbid Qi. The decoction exerts therapeutic effects on vertigo caused by hypertension， stroke， otitis media， Meniere’s disease， and brain tumor as well as benign paroxysmal positional vertigo. Further exploration of the theoretical connotation of mutual inference between clear Qi and turbid Qi and analysis of the pathogenesis of vertigo and the therapeutic effect of Xiao Chaihutang can better interpret the internal correlations among the three， thus providing new ideas for the syndrome differentiation and treatment of vertigo.

Objective: To investigate the current status and trends of depressive symptoms among middle school and college students in Hunan Province, and to explore the primary related factors of depressive symptoms, so as to provide a scientific basis for strengthening mental health among students. Methods: A total of 279 382 students in Hunan Province were selected through a stratified cluster random sampling method from 2021 to 2023. National Survey Questionnaire on Common Diseases and Health Influencing Factors among Students was adopted for the survey, and the Center for Epidemiological Studies Depression Scale was used to assess their depressive symptoms. The χ 2 test and trend χ 2 test were used to analyze depressive symptoms prevalence and trends, and multivariable Logistic regression was used to analyze the related factors of depressive symptoms. Results: The prevalence of depressive symptoms among students in Hunan Province from 2021 to 2023 were 19.66%, 20.17% and 21.47%, respectively, showing an upward trend ( χ 2 trend =9.07, P <0.01). In addition, the results of the multivariable Logistic regression analysis showed that students with healthy diet ( OR=0.43, 95%CI =0.40-0.45), adequate sleep ( OR=0.88, 95%CI =0.86-0.90), and acceptable screen time ( OR=0.61, 95%CI =0.60-0.62) had lower risks in depressive symptoms detection, while students with smoking ( OR= 1.95, 95%CI =1.88-2.02), secondhand smoke exposure ( OR=1.33, 95%CI =1.30-1.36) and Internet addiction ( OR= 4.19 , 95%CI =4.05-4.34) had higher risks in depressive symptoms detection, with differences in the degree of association among different genders, educational stages and urban rural groups ( OR=0.40-6.04, Z =-12.69-11.98) ( P <0.05). Conclusions There is an increasing trend of depressive symptoms among middle school and college students in Hunan Province from 2021 to 2023.Targeted depression prevention measures should be taken for students with different demographic characteristics to promote their mental health.

Hepatic angiomyolipoma （HAML） is a rare benign mesenchymal tumor frequently observed in middle-aged women. Due to the absence of prominent symptoms in the early stage and the lack of specific imaging findings， the diagnosis of this disease can be challenging， leading to a high rate of misdiagnosis. This article reports a case of giant HAML with subcapsular rupture that was misdiagnosed as hepatocellular carcinoma and introduces the characteristics of the case and its diagnosis and treatment process， in order to provide a reference for the diagnosis and treatment of this type of disease.

Osteoarthritis (OA) causes chronic pain that significantly impairs quality of life, with current treatments often proving insufficient and accompanied by adverse effects. Recent research has identified the dorsal root ganglion (DRG) and its resident macrophages as crucial mediators of chronic OA pain through neuroinflammation driven by macrophage polarization. We present a novel injectable thermo-sensitive hydrogel system, KAF@PLEL, designed to deliver an anti-inflammatory peptide (KAF) specifically to the DRG. This biodegradable hydrogel enables sustained KAF release, promoting the reprogramming of DRG macrophages from pro-inflammatory to anti-inflammatory phenotypes. Through comprehensive in vitro and in vivo studies, we evaluated the hydrogel's biocompatibility, effects on macrophage polarization, and therapeutic efficacy in chronic OA pain management. The system demonstrated significant capabilities in preserving macrophage mitochondrial function, suppressing neuroinflammation, alleviating chronic OA pain, reducing cartilage degradation, and improving motor function in OA rat models. The sustained-release properties of KAF@PLEL enabled prolonged therapeutic effects while minimizing systemic exposure and side effects. These findings suggest that KAF@PLEL represents a promising therapeutic approach for improving outcomes in OA patients through targeted, sustained treatment.

Objective:To improve the understanding of patients with diffuse large B-cell lymphoma (DLBCL) with pulmonary cryptococcosis.Methods:The clinical data of 1 DLBCL patient with pulmonary cryptococcosis in the Central Hospital of Fengxian District of Shanghai in May 2023 were retrospectively analyzed, and the relevant literatures were reviewed.Results:This 75-year-old female patient was asymptomatic after 2 cycles of R-CHOP chemotherapy. The high-resolution CT of lung showed that lung nodules were progressively enlarged. Antibacterial treatment was ineffective. Pulmonary cryptococcosis was confirmed by bronchoalveolar lavage fluid (BALF) targeted high-throughput sequencing (tNGS) and cryptococcus capsular antigen (CrAg) detection. The central nervous system was not involved. And the long-term adequate-dose fluconazole was prescribed for 6 months, and the treatment against lymphoma was given synchronously. The lung nodule lesions reduced after antifungal therapy for 1 month. The lung nodules disappeared after the follow-up of 6 months after completion of final chemotherapy. The evaluation of lymphoma indicated complete remission.Conclusions:Pulmonary cryptococcosis occurs insidiously and shows no specific symptoms; its imaging manifestations are variable and routine anti-infection is ineffective. Immunochemotherapy for lymphoma patients is a high-risk factor for cryptococcal infection. tNGS and CrAg testing for BALF are effective methods of the confirmed diagnosis. The early and long-term adequate-dose antifungal treatment is the key to preventing the recurrence or progression.

Objective:To compare the enrichment effects of ultrafiltration, polyethylene glycol (PEG) precipitation, aluminum salt precipitation, and anionic membrane adsorption-elution on viruses in drinking water.Methods:Using phage MS2 as the target virus, three different concentrations of drinking water samples were prepared, and the samples were enriched by ultrafiltration 1, ultrafiltration 2, PEG precipitation, aluminum salt precipitation, and anionic membrane adsorption-elution method, respectively. Real-time fluorescence quantitative reverse transcription-polymerase chain reaction (RT-qPCR) was used to quantify MS2 nucleic acid in pre and post concentrated samples and the recovery rates of MS2 in samples with high, medium and low concentrations were compared among the five methods.Results:Comparing the MS2 enrichment recovery rates of individual enrichment method in water samples of different concentrations, ultrafiltration method 1, PEG precipitation method, aluminum salt precipitation method, and membrane adsorption-elution method were not affected by the sample concentration, and the differences of the recovery rates for the three concentration water samples among the four methods were not statistically significant ( P>0.05). The MS2 enrichment recovery rates of the five enrichment methods were significantly different in all concentration samples ( P<0.05). The recovery rates of ultrafiltration method 1 were higher in all three concentration samples, followed by aluminum salt precipitation and anionic membrane adsorption-elution, PEG precipitation were higher in high concentration samples, but lower in low and medium concentration samples, and the recovery rates of ultrafiltration method 2 were the lowest in all three concentration samples. Comparing the Ct values of MS2 in the enriched samples by five methods, the Ct values of ultrafiltration method 1 were the smallest in the three concentration water samples. There was no statistically significant difference in MS2 Ct values among the five enrichment methods in the medium and high concentration water samples ( P>0.05). In low concentration simulated water samples, only the difference of MS2 Ct value between ultrafiltration method 1 and ultrafiltration method 2 was statistically significant ( Z=16.000, P=0.016). Conclusions:Considering the operation simplicity, operation time and virus recovery rate after enrichment, ultrafiltration was the most effective method for virus enrichment in drinking water.

Objective:To compare postoperative inflammatory markers and surgical outcomes between open reduction and internal fixation versus double reverse traction closed reduction and percutaneous internal fixation for tibial plateau fractures.Methods:A retrospective analysis was conducted of the data of 229 patients with tibial plateau fracture who had been admitted to Department of Orthopaedic Surgery, The Third Hospital of Hebei Medical University from January 2023 to December 2023. There were 155 males and 74 females with an age of (48.7±10.9) years. According to the surgical methods, the patients were divided into 2 groups. A conventional group of 87 cases were treated by open reduction and internal fixation while a minimally invasive group of 142 cases treated with double reverse traction closed reduction and percutaneous internal fixation. The 2 groups were compared in terms of hematological indexes [white blood cell count (WBC), neutrophil count (NEUT), lymphocyte count (LYM), monocyte count (Mono), platelet count (PLT), and albumin (ALB)] and composite inflammatory indexes [neutrophil to lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammatory index (SII), systemic inflammatory response index (SIRI)] before operation and on the first day after operation, intraoperative blood loss, operation time, fracture healing time, Hospital for Special Surgery (HSS) knee score and incidence of thrombosis.Results:There were no significant differences in baseline characteristics or treatment variables between the 2 groups, indicating comparability ( P > 0.05). All the 229 patients were followed up for (16.5±2.8) months. In each group, comparisons between preoperation and postoperation showed that LYM and ALB significantly decreased while WBC, NEUT, Mono, PLT, NLR, PLR, SII and SIRI significantly increased on the first day after operation ( P < 0.05). Preoperatively, there were no significant differences between the 2 groups in terms of hematological or composite inflammatory indexes ( P > 0.05). On the first day after operation, there was no significant difference in WBC, NEUT, LYM, ALB or NLR between the 2 groups ( P > 0.05), but Mono, PLT, PLR, SII and SIRI in the minimally invasive group were significantly lower than those in the conventional group ( P < 0.05). The intraoperative blood loss, operation time, fracture healing time, HSS knee score and incidence of thrombosis in the minimally invasive group were significantly better than those in the conventional group ( P < 0.05). Conclusion:In the treatment of tibial plateau fractures, compared with conventional open reduction and internal fixation, double reverse traction closed reduction and percutaneous internal fixation shows obvious advantages in reducing inflammatory indicators and leads to better surgical outcomes.

AIM:This study aims to investigate the sensitizing effects of lycorine(Lyc)in combination with cisplatin(Cis)on human osteosarcoma cells and to explore the underlying mechanisms of action.METHODS:Human osteosarcoma cell lines MG63,HOS,and cisplatin-resistant HOS/DDP cells were utilized to evaluate the effects of Lyc and cisplatin,both alone and in combination,on cell viability using the CCK8 assay.The clonogenic assay was performed to assess cell proliferation capacity,while the scratch assay evaluated the drugs' effects on cell migration.Reactive oxygen species(ROS)levels were measured using a ROS assay kit,and changes in intracellular glutathione(GSH)levels were assessed with a GSH/oxidized glutathione(GSSG)assay kit.The mitochondrial membrane potential was analyzed via JC-1 staining to determine the drugs' effects on mitochondrial function.Intracellular iron(Ⅱ)content changes were detected us-ing FerrOrange,a fluorescence probe,and cellular malondialdehyde(MDA)levels were measured using an MDA assay kit.RT-qPCR was employed to evaluate the expression levels of key genes related to ferroptosis,and Western blot analysis was conducted to detect changes in the protein expression levels of Yes-associated protein 1(YAP1),acyl-CoA synthetase long-chain family member 4(ACSL4),glutathione peroxidase 4(GPX4),heme oxygenase-1(HO-1),and transferrin re-ceptor(TFRC).RESULTS:Both Lyc and cisplatin effectively inhibited the proliferation of human osteosarcoma cells.Notably,the combination of Lyc and cisplatin led to a more substantial reduction in cell viability,proliferation,and migra-tion abilities in MG63,HOS,and HOS/DDP cells compared to cisplatin alone.Additionally,this combination significant-ly increased ROS levels while decreasing GSH content,indicating mitochondrial damage and elevated iron(Ⅱ)and MDA levels.RT-qPCR results revealed that the combination treatment more significantly downregulated ferroptosis-promoting genes and upregulated ferroptosis-inhibiting genes compared to cisplatin treatment alone(P<0.05).Western blot results showed a slight decrease in GPX4 protein expression following Lyc and cisplatin treatment,while expression levels of YAP1,TFRC,ACSL4,and HO-1 were significantly increased(P<0.05).CONCLUSION:Lyc enhances the sensitivi-ty of MG63,HOS,and HOS/DDP cells to cisplatin by promoting ferroptosis through the YAP1/TFRC signaling pathway.
