OBJECTIVE: To elucidate how spinal manipulative therapy (SMT) exerts its analgesic effects through regulating brain function in lumbar disc herniation (LDH) patients by utilizing resting-state functional magnetic resonance imaging (rs-fMRI). METHODS: From September 2021 to September 2023, we enrolled LDH patients (LDH group, n=31) and age- and sex-matched healthy controls (HCs, n=28). LDH group underwent rs-fMRI at 2 distinct time points (TPs): prior to the initiation of SMT (TP1) and subsequent to the completion of the SMT sessions (TP2). SMT was administered once every other day for 30 min per session, totally 14 treatment sessions over a span of 4 weeks. HCs did not receive SMT treatment and underwent only one fMRI scan. Additionally, participants in LDH group completed clinical questionnaires on pain using the Visual Analog Scale (VAS) and the Japanese Orthopedic Association (JOA) score, whereas HCs did not undergo clinical scale assessments. The effects on the brain were jointly characterized using the amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo). Correlation analyses were conducted between specific brain regions and clinical scales. RESULTS: Following SMT treatment, pain symptoms in LDH patients were notably alleviated and accompanied by evident activation of effects in the brain. In comparison to TP1, TP2 exhibited the most significant increase in ALFF values for Temporal_Sup_R and the most notable decrease in ALFF values for Paracentral_Lobule_L (voxelwise P<0.005; clusters >30; FDR correction). Additionally, the most substantial enhancement in ReHo values was observed for the Cuneus_R, while the most prominent reduction was noted for the Olfactory_R (voxelwise P<0.005; clusters >30; FDR correction). Moreover, a comparative analysis revealed that, in contrast to HCs, LDH patients at TP1 exhibited the most significant increase in ALFF values for Temporal_Pole_Sup_L and the most notable decrease in ALFF values for Frontal_Mid_L (voxelwise P<0.005; clusters >30; FDR correction). Furthermore, the most significant enhancement in ReHo values was observed for Postcentral_L, while the most prominent reduction was identified for ParaHippocampal_L (voxelwise P<0.005; clusters >30; FDR correction). Notably, correlation analysis with clinical scales revealed a robust positive correlation between the Cuneus_R score and the rate of change in the VAS score (r=0.9333, P<0.0001). CONCLUSIONS Long-term chronic lower back pain in patients with LDH manifests significant activation of the "AUN-DMN-S1-SAN" neural circuitry. The visual network, represented by the Cuneus_R, is highly likely to be a key brain network in which the analgesic efficacy of SMT becomes effective in treating LDH patients.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Objective To investigate the status of hearing impaired children's hearing device independence skills,and to explore the ways to improve their self-use of hearing equipment.Methods This study surveyed 64 re-habilitation teachers and 411 parents of children with hearing impairment aged 0-12 years.Through face-to-face or remote telephone interview,3 good habits(A asking parents for advice before removing the HA,B putting the de-vice into a moisture-proof box after removing it,C bringing batteries to school and knowing where are them)and 3 key abilities[D wearing the device independently,E replacing the battery independently,and F independently handle foreign bodies in the ear mold(Fa)and water vapor(Fb)]was investigated.The age when mastering skills or de-veloping habits difference of hearing impaired children in different groups were compared.Results ① The ratio of ability D in the bilateral CI group and the bilateral HA group of preschool children was 30.97％and 18.57％respec-tively.Among elementary school children,85.29％and 90.70％had this ability respectively.② The ratio of ability E in the bilateral CI group,the bilateral HA group and the bimodel group were 11.50％,15.71％and 16.49％,re-spectively.Among elementary school children,64.71％,53.49％and 68.52％had this ability,respectively.③Among preschool children,there was no statistical difference in age when different equipment groups developed the three good habits and acquired ability D and E(P＞0.05).④ Among primary school children,there was a statisti-cal difference in the age when different equipment groups formed habit A(P＜0.05),and the age when double CI group had this ability was slightly earlier than the double HA group.There was no significant difference in other abilities among age groups(P＞0.05).Conclusion The age at which hearing impaired children develop the three good habits precedes the age at which they master the key skills,which accords with the law of skill acquisition and development of ordinary children.Corresponding teaching process should be based on the age and ability of hearing-impaired children without considering the type of equipment.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To analyze the symptoms,diagnosis and treatment of upper urinary tract calculi patients combined with mild and moderate benign prostatic hyperplasia(BPH)after ureteral stent implantation.Methods:One hundred and six BPH pa-tients who were hospitalized for upper urinary tract calculi and had ureteral stents retained from January 2019 to December 2022 were selected and divided into 2 weeks group and 4 weeks group according to the time of removal of ureteral stents after surgery.Their gener-al clinical data were analyzed and compared.International Prostatic Symptom Scale(IPSS),postoperative ureteral Stent Symptom Questionnaire(USSQ),and incidence of adverse events after ureteral stent removal were recorded before and after removal.Results:The scores of IPSS were significantly increased in all patients,and symptoms in urinary tract had improved significantly after discharge(P＜0.05).Compared with the 2 weeks group,the USSQ score of the 4 weeks group was significantly increased(P＜0.05).And no significant adverse event was observed in the 2 weeks group after the removal of ureteral sten.Conclusion:IPSS score and USSQ score increased significantly during stent implantation in BPH patients with lithiasis.And complications increased sig-nificantly over time.Following thorough clinical assessment,early ureteral stent removal demonstrates both safety and efficacy,repre-senting an optimal therapeutic approach in selected cases.

Objective:To analyze two families with inherited dysfibrinogenemia,and explore the molecular pathogenic mechanisms.Methods:The coagulation indexes of the probands and their family members were detected.The FGA,FGB,and FGG exons and their flanking sequences were amplified by PCR,and the mutation sites were identified by sequencing.SIFT,PolyPhen2,LRT,ReVe,MutationTaster,phyloP,and phastCons bioinformatics software were used to predict the functional impact of the mutation sites.Protein structure and amino acid conservation analysis of the variant were conducted using PyMOL and Clustal X software.Results:The thrombin time(TT)of the proband in family 1 was prolonged to 37.00 s,and Fg:C decreased to 0.52 g/L.The TT of the proband in family 2 was 20.30 s,and Fg:C was 1.00 g/L,which was lower than the normal range.Genetic analysis revealed that the proband in family 1 had a heterozygous mutation c.80T＞C in FGA,resulting in the substitution of phenylalanine 27 with serine(Phe27Ser).The proband in family 2 had a heterozygous mutation c.1007T＞A in FGG,resulting in the substitution of methionine 336 with lysine(Met336Lys).Bioinformatics software prediction analysis indicated that both mutations were deleterious variants.PyMOL mutation models revealed that the Aα chain mutation(Phe27Ser)in family 1 and y chain mutation(Met336Lys)in family 2 resulted in alterations in spatial structure and reduced protein stability.Clustal X results showed that both Aα Phe27 and γMet336 were highly conserved across homologous species.Conclusion:Heterozygous mutations of FGA gene c.80T＞C and FGG gene c.1007T＞A are both pathogenic variants,causing inherited dysfibrinogenemia.

Abstract: Objective　To analyze the surveillance of Mycobacterium tuberculosis/HIV (TB/HIV) co-infection in Liaoning Province from 2016 to 2021, providing a scientific basis for formulating future prevention and control measures applicable to the province-wide co-infection. Methods　A descriptive analysis was conducted on patient registration, two-way screening, and treatment information from the annual report of patients with TB/HIV co-infection in Liaoning Province from 2016 to 2021. Results From 2016 to 2021, 222 cases of TB/HIV co-infection were registered in Liaoning Province, accounting for 0.16% (222/136 709) of TB patients and 1.42% (222/15 584) of HIV/AIDS patients. In HIV/AIDS, the symptom screening rate was 96.01%, showing a downward trend (χ2trend=982.28, P<0.05). The TB detection rate was 0.47%, also showing a downward trend (χ2trend=36.56, P<0.05), while the chest radiograph or sputum detection rate was 94.61%, showing an overall upward trend (χ2trend=96.5, P<0.05). Among TB patients, 65 188 were tested for HIV antibodies, with a detection rate of 47.68%, which showed an overall upward trend (χ2trend=3 326.38, P<0.05). There were 39 HIV-positive cases detected, with the positive detection rate in TB patients decreasing from 0.12% to 0.07%. From 2016 to 2021, the majority of co-infected patients were male and ≥15 years old, with 496 cases (92.36%) of males and 41 cases (7.64%) of females. Among the 537 patients with co-infection, 47 cases (8.75%) received anti-tuberculosis therapy alone, 72 cases (13.41%) received anti-HIV therapy alone, and 408 cases (75.98%) received combined therapy, with an overall downward trend (χ2trend=9.54, P<0.05). Conclusions Focus should be placed on the male population and those aged ≥15 years, with future efforts aimed at enhancing two-way screening work among TB and HIV/AIDS patients and improving the rate of combined treatment.

Objective To study the inhibitory effect of Huidu Yinhua powder from the Orthodox Manual of External Medicine on methicillin-resistant Staphylococcus aureus(MRSA),virulence factor α-hemolysin(Hla)activity,and biofilm formation,and to explore the optimal ratios of Huidu Yinhua powder and provide experimental support for its use.Methods The inhibitory effects of Huidu Yinhua powder and the herbs in the formula on USA300 were analyzed by the minimum inhibitory concentration(MIC),minimum bactericidal concentration(MBC),and disk diffusion assay(K-B method).Hemolysis,neutralization,oligomerization,and Western blot assays were used to verify in which form the drug inhibits the activity of virulence factor α-hemolysin(Hla).A biofilm assay was performed to evaluate the inhibitory effect of Huidu Yinhua powder on biofilm.Orthogonal experiments were performed to explore the optimal ratio of Huidu Yinhua powder.Results Huidu Yinhua powder inhibited the MRSA strain with a MIC90 of 64 mg/mL and an MBC of 256 mg/mL with antibacterial circle diameter of(7.50±0.50)mm.Huidu Yinhua powder inhibited Hla activity by inhibiting Hla secretion.The minimum effective concentration(MEC)was 16 mg/mL,and the MEC of biofilm was 8 mg/mL.In Huidu Yinhua powder,honeysuckle and astragalus only affected the hemolytic activity of MRSA and biofilm formation without inhibiting bacterial growth.The hemolytic activity and biofilm of MEC were both 32 mg/mL.Glycyrrhiza had a strong bacterial inhibitory capacity with a MIC90 of 8 mg/mL and biofilm MEC of 1 mg/mL without showing inhibitory hemolytic activity at subinhibitory concentrations.The orthogonal experiment showed that,at a ratio of honeysuckle,astragalus,and glycyrrhiza in Huidu Yinhua powder of 1∶2∶4,the MIC90 was 16 mg/mL,MEC of hemolytic activity was 8 mg/mL and that of biofilm was 4 mg/mL,both of which were the lowest among the nine groups.Conclusions Huidu Yinhua powder affects the hemolytic activity and biofilm formation of MRSA at subinhibitory concentrations with the optimal ratio of honeysuckle,astragalus,and glycyrrhiza being 1∶2∶4.
