This article systematically analyzes the historical evolution of the name， origin， quality evaluation， harvesting， processing and other aspects of Picrorhizae Rhizoma by referring to the medical books， prescription books， and other documents of the past dynasties， combined with relevant modern research materials， in order to provide a basis for the development and utilization of famous classical formulas containing this medicinal herb. The research results indicate that Picrorhizae Rhizoma was first recorded in New Revised Materia Medica from the Tang dynasty. Throughout history， Huhuanglian has been used as its official name， and there are also aliases such as Gehu Luze， Jiahuanglian and Hulian. The main source of past dynasties is the the rhizomes of Picrorhiza kurrooa and P. scrophulariiflora. In ancient times， Picrorhizae Rhizoma was mainly imported by foreign traders via Guangzhou and other regions， and also produced in China， mainly in Xizang. In ancient times， it was harvested and dried in early August of the lunar calendar， while in modern times， it is mostly harvested from July to September， with the best quality being those with thick and crispy rhizomes without impurities， and bitter taste. Throughout history， Picrorhizae Rhizoma was collected， washed， sliced， and dried before being used as a raw material for medicine， it has a bitter and cold taste， mainly used to treat bone steaming， hot flashes， infantile chancre fever， and dysentery. There is no significant difference in taste and efficacy between ancient and modern times. Based on the research results， it is recommended that the rhizomes of P. scrophulariiflora in the 2020 edition of Chinese Pharmacopoeia， or the rhizomes of P. kurrooa， can be used in famous classical formulas containing this medicinal herb， which can be processed according to the processing requirements marked by the original formula. For those without clear processing requirements， the dried raw products are used as medicine.

Carbamate pesticides, a new type of broad-spectrum pesticides for controlling pests, mites, and weeds, are developed to address the shortcomings of organochlorine and organophosphorus pesticides. Their widespread use and slow degradation have led to environmental pollution, causing damage to ecosystems and human health. Managing pesticide residues is a pressing issue in the current environmental protection. This study aims to investigate the expression of SyEst870, a member of the SGNH/GDSL hydrolase family in Sphingobium yanoikuyae, in a prokaryotic system and evaluate the ability of the recombinant protein to degrade carbamate pesticides. The prokaryotic expression vector pET-32a-SyEst870 was constructed and transformed into the Escherichia coli BL21 for heterologous expression. The purified protein was studied in terms of enzyme activity and effects of temperature, pH, and metal ions on the enzyme activity, with p-nitrophenol acetate as the substrate and based on the standard curve of p-nitrophenol. LC-MS (liquid chromatography-mass spectrometry) was employed to examine the degradation effects of SyEst870 on carbaryl, metolcarb, and isoprocarb. GC-MS (gas chromatography-mass spectrometry) was employed to detect the degradation products of SyEst870 for the three pesticides. The soluble protein SyEst870 was successfully obtained through the heterologous expression in Escherichia coli, which yielded an enzyme with the activity of 677.5 U after affinity chromatography. SyEst870 exhibited degradation rates of 82.34%, 84.43%, and 92.87% for carbaryl, metolcarb, and isoprocarb, respectively, at an initial concentration of 100 mg/L within 24 h at 30 ℃ and pH 7.0. The primary degradation products of carbaryl were identified as α-naphthol and methyl isocyanate. Metolcarb was mainly degraded into m-cresol and methyl isocyanate, and isoprocarb was mainly degraded into 2-isopropylphenol and methyl isocyanate. Compared with the half-life of carbamate pesticides in the natural environment, which ranges from a few days to several weeks, the recombinant protein SyEst870 can rapidly eliminate the residues of carbamate pesticides. This study lays a foundation for addressing pesticide residues in the environment and in fruits and vegetables.

Objective Guided by the"central-peripheral-central"theory,this study analyzed the influ-ence of repeated transcranial magnetic stimulation(rTMS)combined with intelligent rehabilitation robot hand training on the rehabilitation effect of stroke patients in the convalesce stage,in order to provide more new ide-as for clinical patients.Methods A total of 86 stroke patients who were treated in the department of rehabili-tation in Integrated Traditional and Western Medicine Hospital of Linping District,Hangzhou from July 2021 to July 2024 were prospectively selected and divided into observation group(n=43)and control group(n=43)by random number table method.The observation group received rTMS based"central-peripheral-central"theory combined with intelligent rehabilitation robot hand training on the basis of routine rehabilitation,while the control group received intelligent rehabilitation robot hand training combined with rTMS pseudo-stimula-tion intervention on the basis of routine rehabilitation.The changes of upper Fugl-Meyer motor function as-sessment(FMA),Modified Barthel Index(MBI),upper limb movement pattern(Brunnstrom Staging Scale)and joint motion before and after intervention were recorded in two groups.Results After intervention,the scores of FMA and MBI in two groups were higher than before intervention,and the observation group was significantly higher than that of the control group(P＜0.05).After intervention,the rate of patients in Brunnstrom stage Ⅱ was decreased,while the rates of patients in Brunnstrom stage Ⅲ and Ⅳ were increased,and the observation group was better than the control group(P＜0.05).After the intervention,the motion degrees of shoulder forward flexion,shoulder abduction,shoulder back extension,elbow flexion,elbow exten-sion,forearm pronation,forearm pronation,carpal palm flexion and wrist back extension in two groups were significantly higher than that before the intervention,and the observation group was significantly higher than the control group(P＜0.05).Conclusion Intelligent rehabilitation robot hand training combined with rTMS can improve upper limb active joint motion,upper limb motor function and daily living ability of stroke pa-tients in the convalescence period.

Objective To discuss the application of ankle pump exercise with colorful ring counting command in improving the blood hypercoagulable state in patients after hepatic arterial infusion chemotherapy(HAIC).Methods A total of 105 patients,who received HAIC at the Interventional Department of a certain Grade A general hospital in Fujian Province of China from January to December of 2023,were collected.The 53 patients who received treatment from January to June of 2023 were used as the control group,and the other 52 patients who received treatment from July to December of 2023 were used as the study group.The postoperative routine nursing and ankle pump exercise was employed for the patients of the control group,while ankle pump exercise with colorful ring counting command on the basis of postoperative routine nursing was carried out for the patients of the study group.The resting status of popliteal vein,the maximum and average systolic blood flow velocity at the end of exercise,the changes in coagulation index,the incidence of deep vein thrombosis,and the compliance of ankle pump were compared between the two groups.Results There were no statistically significant differences in the resting popliteal vein blood flow velocity and incidence of deep vein thrombosis between the two groups(P＞0.05).The maximum and average popliteal vein blood flow velocity at the end of exercise in the study group were higher than those in the control group.The levels of PT,APTT,FBG,TT and D-dimer(D-D)at 72 hours after HAIC were lower than those in the control group(all P＜0.05),and the compliance of ankle pump exercise in the study group was better than that in the control group(P＜0.05).Conclusion Ankle pump exercise with colorful ring counting command can accelerate lower limb blood flow velocity,improve the blood hypercoagulable state,and improve compliance with ankle pump exercise in patients after receiving HAIC.

OBJECTIVE To investigate the in vitro anti-inflammatory effects and mechanisms of oblongifolins A （OA） extracted from Garcinia oblongifolia. METHODS RAW264.7 cells were used as the research subject and divided into control group （0.5% DMSO）， lipopolysaccharide （LPS） group （1 μg/mL）， DEX group （10 µmol/L DEX+1 μg/mL LPS）， and low-， medium-， and high-concentration groups of OA （7.5， 15， 30 µmol/L OA+1 μg/mL LPS）. Except for the control group， the remaining groups were first stimulated with LPS for 1 hour and then mixed with drugs for 24 hours. The morphological changes of cells were observed in each group. The contents of nitric oxide （NO）， reactive oxygen species （ROS）， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， IL-1β， IL-4 and IL-10 were detected in cells of each group； mRNA expression levels of TNF-α， IL-6 and IL-1β were measured. The expression of key proteins in the nuclear factor κB （NF-κB） and nuclear factor-erythroid 2-related factor 2 （Nrf2） signaling pathways in each group， as well as the nuclear translocation of NF-κB p65 and Nrf2 proteins in control group， LPS group and OA high-concentration group， were detected. RESULTS Compared to the LPS group， the number of spindle-shaped and irregular cells gradually decreased in OA groups， the contents of NO， ROS （except for OA low-concentration group）， TNF-α， IL-6 and IL-1β， the mRNA expressions of TNF-α， IL-6 （except for OA low-concentration group） and IL-1β as well as the protein expressions of phosphorylated NF-κB p65 （p-NF-κB p65）， p-IκBα， and Kelch-like ECH-associated protein 1 （Keap1） were decreased significantly （P＜0.05）. The contents of IL-4 and IL-10， protein expressions of IκBα， Nrf2 （except for OA low- and medium-concentration groups）， HO-1 （except for OA low-concentration group） and NQO1 were all increased significantly （P＜0.05）. OA of high concentration could inhibit NF-κB p65 protein nuclear translocation and promote Nrf2 protein nuclear translocation. CONCLUSIONS OA can suppress LPS-induced inflammation in RAW264.7 macrophages. The underlying molecular mechanism likely entails the inhibition of the NF-κB signaling pathway， the activation of the Nrf2 signaling pathway and the reduction of ROS and inflammatory factor release.

Objective To apply cone beam CT measurements(CBCT)to analyze the effect of skeletal Class Ⅲ high angle with devia-tion on upper airway morphology and hyoid position.Methods A total of 120 patients with skeletal Class Ⅲ high angle malocclusion who visited our hospital from September 2019 to December 2022 were selected.CBCT was taken in all subjects.According to the degree of mandibular deviation(MD)of the point under the chin from the median sagittal plane,the 120 patients were divided into three groups:non-migratory,mildly migratory,and severely migratory groups,and the volume of the upper airway as well as the position of the hyoid bone of three groups were measured and analyzed respectively.Results There was no significant difference in the volume and minimum cross-sectional area of the nasopharyngeal segment,palatopharyngeal segment,and minimum cross-sectional area of the laryngopharyngeal segment.No siginificant difference was found between the position of the hyoid bone(HB)on the Y-axis(Y-HB)and the position of the hyoid bone on the Z-axis(Z-HB)among the three groups(P＞0.05).Compared with the other two groups,the vol-ume and total volume of the nasopharyngeal segment,the laryngopharyngeal segment,and minimum cross-sectional area of the laryngo-pharyngeal segment in the group of severe deviation were significantly reduced(P＜0.05)and X-HB was significantly larger(P＜0.05).Conclusion In patients with skeletal ClassⅢhyperkeratosis with severe deviation,the total volume of the glossopharyngeal segment,laryngopharyngeal segment,and upper airway,as well as the minimum cross-sectional area of the glossopharyngeal segment were smal-ler than those of the othertwo groups.In patients with severe deviation,the position of the hyoid bone(HB)in the X-axis(X-HB)was larger than that of the non-migratory group,indicating that migratory jaws mainly affect the morphology of the lingual-pharyngeal seg-ment as well as the laryngopharyngeal segment of the upper airway;the effect of migratory jaws on the hyoid bone is reflected in the X-HB,indicating that migratory jaws can lead to the deviation of the hyoid bone from the median sagittal plane.

Objective To explore the predictive value of serum homo sapiens microRNA(hsa-miR)-30c-5p expression in patients with type 2 diabetes mellitus(T2DM)for microvascular complications.Methods A total of 205 T2DM patients admitted to Bazhong Central Hospital from May 2021 to September 2022 were selected as the diabetes group,and the diabetes group was further divided into diabetes with combined group(n=124)and non combined group(n=81)according to the microvascular complications of the patients.In addition,205 healthy people who underwent physical examination during the same period were selected as the control group.The expression of hsa-miR-30c-5p in serum was detected by reverse transcription-polymerase chain reaction(RT-PCR)and compared.The factors affecting microvascular complications were analyzed using multivariate logistic regression analysis,and receiver operating characteristic(ROC)curves were plotted to predict the value of serum hsa-miR-30c-5p expression in predicting microvascular complications in T2DM patients.Results The expression of serum hsa-miR-30c-5p in the combined group(0.58±0.06)and the non-combined group(0.72±0.08)were lower than that in the control group(0.89±0.21),and the differences were significant(t=16.038,7.079,all P=0.001).The combined group was lower than the non-combined group,and the difference was significant(t=14.289,P=0.001).The course of diabetes[(OR(95％CI):3.873(2.976～4.770)],uric acid[(OR(95％CI):2.125(1.211～3.040)]and glycosylated hemoglobin[(OR(95％CI):2.680(1.745～3.616)]were independent risk factors for microvascular complications in T2DM patients(all P＜0.05),while the time within the target range of glucose[(OR(95％CI):0.491(0.135～0.846)]and serum hsa-miR-30c-5p[(OR(95％CI):0.532(2.976～4.770)]were protective factors for microvascular complications in T2DM patients(all P＜0.05).The sensitivity,specificity and area under the curve(95％CI)of serum hsa-mir-30c-5p expression in predicting microvascular complications in T2DM patients were 81.45％,85.19％and 0.802(0.741～0.854),respectively.Conclusion The expression of serum hsa-miR-30c-5p in patients with T2DM is abnormally reduced,and serum hsa-miR-30c-5p is a protective factor for microvascular complications in patients with T2DM.It may have a certain predictive value for microvascular complications in patients with T2DM.

Objective To investigate the application of mycophenolate mofetil(MMF)in oral mucosal pemphigoid and provide a clinical reference.Methods One case of glucocorticoids combined with MMF in the treatment of oral mucosal pemphigoid was reported,and the clinical application of MMF in oral mucosa-related bullous diseases was dis-cussed.Results One patient with a clinical diagnosis of"oral mucosal pemphigoid"was treated with methylpredniso-lone(36 mg,qd,morning dose)or combined hydroxychloroquine sulfate(0.1 g/time,bid)and thalidomide capsules(50 mg,qd,bedtime)and other drugs.The patient's disease was slowly controlled but prone to recurrence.The treat-ment regimen was immediately adjusted,i.e.,methylprednisolone(36 mg,qd,morning dose)was combined with MMF(0.5 g/time,bid)for 2 weeks,which resulted in ideal lesion healing control.After 8 weeks of methylprednisolone com-bined with MMF,the dose of methylprednisolone was gradually reduced to 12 mg,qd,and MMF was reduced to 0.5 g,qd,the patient's symptoms improved significantly,and no obvious lesions were found in the mouth.The dose was then reduced and maintained according to the principle of pemphigoid treatment.Methylprednisolone(8 mg,qd,morning dose)and MMF(0.5 g,qd)have been used for 6 months of maintenance treatment,and they are still being followed up.As yet,the patient's condition is stable without obvious lesions and new blisters,and no obvious side effects have been observed.A review of the literature shows that MMF is widely used in the field of dermatology to treat a variety of im-mune diseases,such as connective tissue diseases and autoimmune blistering diseases.According to the reports of ad-verse reactions to MMF,digestive system reactions are the most common adverse reactions;therefore,patients with ac-tive gastrointestinal diseases should be treated with caution,followed by bone marrow suppression,and it is recommend-ed to monitor liver function and blood routine in patients using MMF.The safety and efficacy of MMF for treating pem-phigoid involving the skin have been reported in the literature,but oral mucosal doctors still lack experience for treating mucous membrane pemphigoid.Conclusions As a new immunosuppressant,MMF has high safety and no obvious side effects and can be considered as a combination adjuvant drug for patients with severe clinical disease and refractory oral mucosal pemphigoid.

Objective:To observe and verify the changes of transcriptome in hyperoxia-induced acute lung injury (HALI), and to further clarify the changes of pathways in HALI.Methods:Twelve healthy male C57BL/6J mice were randomly divided into normoxia group and HALI group according to the random number table, with 6 mice in each group. The mice in the normoxia group were fed normally in the room, and the mice in the HALI group was exposed to 95% oxygen to reproduce the HALI animal model. After 72 hours of hyperoxia exposure, the lung tissues were taken for transcriptome sequencing, and then Kyoto Encyclopedia of Genes and Genomes database (KEGG) pathway enrichment analysis was performed. The pathological changes of lung tissue were observed under light microscope after hematoxylin-eosin (HE) staining. Real-time fluorescence quantitative reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting were used to verify the key molecules in the signal pathways closely related to HALI identified by transcriptomics analysis.Results:Transcriptomic analysis showed that hyperoxia induced 537 differentially expressed genes in lung tissue of mice as compared with the normoxia group including 239 up-regulated genes and 298 down-regulated genes. Further KEGG pathway enrichment analysis identified 20 most significantly enriched pathway entries, and the top three pathways were ferroptosis signaling pathway, p53 signaling pathway and glutathione (GSH) metabolism signaling pathway. The related genes in the ferroptosis signaling pathway included the up-regulated gene heme oxygenase-1 (HO-1) and the down-regulated gene solute carrier family 7 member 11 (SLC7A11). The related genes in the p53 signaling pathway included the up-regulated gene tumor suppressor gene p53 and the down-regulated gene murine double minute 2 (MDM2). The related gene in the GSH metabolic signaling pathway was up-regulated gene glutaredoxin 1 (Grx1). The light microscope showed that the pulmonary alveolar structure of the normoxia group was normal. In the HALI group, the pulmonary alveolar septum widened and thickened, and the alveolar cavity shrank or disappeared. RT-RCR and Western blotting confirmed that compared with the normoxia group, the mRNA and protein expressions of HO-1 and p53 in lung tissue of the HALI group were significantly increased [HO-1 mRNA (2 -ΔΔCt): 2.16±0.17 vs. 1.00±0.00, HO-1 protein (HO-1/β-actin): 1.05±0.01 vs. 0.79±0.01, p53 mRNA (2 -ΔΔCt): 2.52±0.13 vs. 1.00±0.00, p53 protein (p53/β-actin): 1.12±0.02 vs. 0.58±0.03, all P < 0.05], and the mRNA and protein expressions of Grx1, MDM2, SLC7A11 were significantly decreased [Grx1 mRNA (2 -ΔΔCt): 0.53±0.05 vs. 1.00±0.00, Grx1 protein (Grx1/β-actin): 0.54±0.03 vs. 0.93±0.01, MDM2 mRNA (2 -ΔΔCt): 0.48±0.03 vs. 1.00±0.00, MDM2 protein (MDM2/β-actin): 0.57±0.02 vs. 1.05±0.01, SLC7A11 mRNA (2 -ΔΔCt): 0.50±0.06 vs. 1.00±0.00, SLC7A11 protein (SLC7A11/β-actin): 0.72±0.03 vs. 0.98±0.01, all P < 0.05]. Conclusions:HALI is closely related to ferroptosis, p53 and GSH metabolism signaling pathways. Targeting the key targets in ferroptosis, p53 and GSH metabolism signaling pathways may be an important strategy for the prevention and treatment of HALI.
