In this study， a retrospective analysis was performed for the clinical data and electromyography findings of two patients with genetically confirmed hereditary neuropathy with liability to pressure palsies （HNPP）. Electromyography examination showed that both patients had extensive peripheral nerve injuries involving motor and sensory nerve functions， and reductions in both MNCV and SNCV were observed at the sites with liability to nerve compression. Both patients carried heterozygous deletion mutations of the peripheral myelin protein 22 gene. This article analyzes the clinical manifestations， electromyography findings， and genetic testing results of two patients with HNPP and conducts a literature review， in order to provide a reference for the diagnosis， treatment， and prognosis of HNPP in clinical practice.

Objective:To compare the clinical efficacy and effects on cognitive function of magnetic seizure therapy (MST) and modified electroconvulsive therapy (MECT) in the treatment of major depressive episode (MDE).Methods:From January 1, 2019 to December 31, 2021, 40 patients who met the MDE diagnostic criteria in the fifth edition of the Diagnostic Statistical Manual of Mental Disorders (DSM-5) were selected in Shanghai Mental Health Center. Participants were randomly assigned to MECT therapy group (20 patients) and MST therapy group (20 patients) using the random number table method. Both groups received MECT or MST while using serotonin reuptake inhibitors (SSRIs), 3 times a week for 4 weeks. The 17-items Hamilton Depression Rating Scale (HAMD 17) and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) were performed before and after treatment. HAMD 17 reduction rate and effective rate were the main assessment indicators, while RBANS total score and factor scores were considered as the secondary assessment indicators. T-test was used to compare the reduction rate of HAMD 17 between the two groups, and corrected Chi-square test or Fisher′s exact probability method was used to compare the effective rate of treatment between the two groups. HAMD 17 scores and RBANS scores before and after treatment were compared using two-factor repeated measure ANOVA. Results:There were no significant differences in baseline HAMD 17 scores and RBANS scores between 2 groups( t=0.29, P=0.773; t=0.67, P=0.509). The treatment effective rate in the MECT group was 90% (18/20), and the average reduction rate of HAMD 17 was 67.9%. Meanwhile, the effective rate of MST group was 75% (15/20), and the average reduction rate of HAMD 17 was 60.9%. There was no significant difference in the reduction rate and effective rate of HAMD 17 between the two groups ( t=0.69, P=0.493; χ2=0.16, P=0.693). The total scores and factor scores of RBANS after treatment were lower than those before treatment, with statistical significance(total scores: F=19.29, P<0.001;immediate memory score: F=6.22, P=0.020; language function score: F=9.13, P=0.006;attention score: F=5.23, P=0.031;delayed memory score: F=35.90, P<0.001). There was no significant difference in the total scores and factor scores of RBANS before and after treatment in MST group(total scores: F=0.49, P=0.490;immediate memory score: F=2.25, P=0.147;language function score: F=1.22, P=0.280;attention score: F=0.23, P=0.640;delayed memory score: F=0.02, P=0.887). Conclusions:The efficacy of MST treatment and MECT treatment in treating MDE patients seems to be comparable. MDE patients receiving MST had less impact on cognitive function compared to those treated with MECT.

Objective To discuss the regulatory mechanism of nucleotide-binding oligomerzation domain 2(NOD2)/receptor interacting protein 2(RIP2)signaling pathway on inflammatory activation of macrophages in intestinal mucosa and provide experimental evidence for intestinal mucosal inflammation caused by bacterial products.Methods Using the THP-1 monocyte cell line,macrophages were stimulated with muramyl dipeptide(MDP)at varying concentrations and durations.mRNA and protein expression levels of NOD2 and RIP2 were detected.The secretion levels of tumor necrosis factor(TNF)-α and interleukin(IL)-1β in the cell culture supernatant were measured.The most effective siRNA targeting RIP2 and optimal transfection concentration were screened,and the impact of RIP2 gene silencing on MDP-induced inflammatory activation of macrophages was observed.Results After silencing the RIP2 gene,MDP induced a significant decrease in TNF-α and IL-1βsecretion in macrophages,but the changes in cell phenotype were not significantly affected.Conclusion This study revealed the important role of NOD2/RIP2 signaling pathway in inflammatory activation of macrophages,and it is possible to effectively inhibit inflammatory activation of macrophages by interfering with this signaling pathway.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

Opioid analgesics are currently known as the best analgesics. However， toxicity and side effects such as constipation， tolerance and addiction severely limit their clinical application. With the in-depth understanding of the signal transduction mechanism of opioid receptors and the continuous advancement of drug design technology， researchers have managed to develop many promising new methods to get low-toxic and more efficient opioid analgesics， which are different from the traditional morphine skeleton structure modifications. This article focuses on three new research strategies of G-protein biased activation，“ one drug-multiple targets” and peripheral activation. The basic principles of relative separation of analgesic activity and adverse drug reaction by each strategy are introduced， and the latest research progress of representative drugs is briefly reviewed. Among them， the recently approved novel opioid analgesics oliceridine and tegileridine are G-protein biased μ-opioid receptor agonists， Cebranopadol is a typical “one drug-multiple targets” analgesic， and NFEPP is a representative drug of peripheral opioid receptor agonists. The above several strategies complement each other and provide reference for the development of new opioid analgesic drugs.

The standardized workflow of computer-aided static guided implant surgery includes preoperative exami-nation,data acquisition,guide design,guide fabrication and surgery.Errors may occur at each step,leading to irrevers-ible cumulative effects and thus impacting the accuracy of implant placement.However,clinicians tend to focus on fac-tors causing errors in surgical operations,ignoring the possibility of irreversible errors in nonstandard guided surgery.Based on the clinical practice of domestic experts and research progress at home and abroad,this paper summarizes the sources of errors in guided implant surgery from the perspectives of preoperative inspection,data collection,guide de-signing and manufacturing and describes strategies to resolve errors so as to gain expert consensus.Consensus recom-mendation:1.Preoperative considerations:the appropriate implant guide type should be selected according to the pa-tient's oral condition before surgery,and a retaining screw-assisted support guide should be selected if necessary.2.Da-ta acquisition should be standardized as much as possible,including beam CT and extraoral scanning.CBCT performed with the patient's head fixed and with a small field of view is recommended.For patients with metal prostheses inside the mouth,a registration marker guide should be used,and the ambient temperature and light of the external oral scan-ner should be reasonably controlled.3.Optimization of computer-aided design:it is recommended to select a handle-guided planting system and a closed metal sleeve and to register images by overlapping markers.Properly designing the retaining screws,extending the support structure of the guide plate and increasing the length of the guide section are methods to feasibly reduce the incidence of surgical errors.4.Improving computer-aided production:it is also crucial to set the best printing parameters according to different printing technologies and to choose the most appropriate postpro-cessing procedures.

Objective To examine the precise function of influenza A virus target genes(IATGs)in malignancy. Methods Using multi-omics data from the TCGA and TCPA datasets,33 tumor types were evaluated for IATGs.IATG expression in cancer cells was analyzed using transcriptome analysis.Copy number variation(CNV)was assessed using GISTICS 2.0.Spearman's analysis was used to correlate mRNA expression with methylation levels.GSEA was used for the enrichment analysis.Pearson's correlation analysis was used to examine the association between IATG mRNA expression and IC50.The ImmuCellAI algorithm was used to calculate the infiltration scores of 24 immune cell types. Results In 13 solid tumors,IATG mRNA levels were atypically expressed.Except for UCS,UVM,KICH,PCPG,THCA,CHOL,LAMI,and MESO,most cancers contained somatic IATG mutations.The main types of CNVs in IATGs are heterozygous amplifications and deletions.In most tumors,IATG mRNA expression is adversely associated with methylation.RT-PCR demonstrated that EGFR,ANXA5,CACNA1C,CD209,UVRAG were upregulated and CLEC4M was downregulated in KIRC cell lines,consistent with the TCGA and GTEx data. Conclusion Genomic changes and clinical characteristics of IATGs were identified,which may offer fresh perspectives linking the influenza A virus to cancer.

Objective:To study and verify the molecular mechanism of Duzhong Pills for osteoporosis (OP) by means of network pharmacology and molecular docking.Methods:The main chemical components of Duzhong Pills were mined by TCMSP database and the related targets were predicted. The potential targets of osteoporosis in GeneCards, DisGeNET and OMIM databases were searched and the common targets of both were obtained. The STRING platform was used for protein interaction analysis and PPI network diagram was made. The common targets were imported into the David database for enrichment analysis of GO and KEGG pathways, and molecular docking of the main components and core targets was performed. Eighteen Sprague-Dawley rats were divided into control group, model group and Duzhong Pills group according to random number table method, with 6 rats in each group. Ovariectomy was used to make osteoporosis model in model group and Duzhong Pills group. Duzhong Pills group was intragaxed with Duzhong Pills extract of 5 g/kg, and control group and model group were intragaxed with normal saline of the same volume, once a day for 8 weeks. Serum levels of TNF-α, IL-6 and IL-1β were detected by ELISA, and femur PI3K and Akt were detected by Western blot.Results:34 active components were obtained from Duzhong Pills, corresponding to 243 targets, and 1 059 targets for osteoporosis. The core targets included TNF-α, IL-6, AKT1, TP53, IL-1β and others regulated osteoporosis through PI3K-Akt and TNF pathway. The experimental results indicated that compared with model group, the levels of serum TNF-α, IL-6 and IL-1β in Duzhong Pills group decreased ( P<0.05), and the expressions of PI3K and Akt in femur decreased ( P<0.05). Conclusion:Through β-sitosterol, quercetin, kaempferol and other active components, Duzhong Pills can act on TNF, IL-6, AKT1, TP53, IL-1β and other targets, regulating PI3K-Akt signaling pathway, TNF signaling pathway and other signaling pathways to play a role in the treatment of osteoporosis.
