Methods: A total of 72 breast cancer patients with CIPN were randomly divided into two groups. The treatment group (36 cases) was treated with oral methylcobalamin plus ultrasonic medicine permeating Zhuyu Juanbi formulae, while the control group (36 cases) was treated with oral methylcobalamin alone. Following two 2 cycles of continuous treatment, the efficacy of peripheral neurotoxicity, TCM syndrome score, FACT/GOG-Ntx score, total neuropathy score, and safety indicators of gynecological cancer patients were observed in the two groups. Result: In the treatment of CIPN, the addition of ultrasonic medicine permeating Zhuyu Juanbi formulae was more effective than oral methylcobalamin alone in reducing peripheral neurotoxicity and improving the quality of life of patients. The difference between the two groups was statistically significant (P < 0.05), and ultrasound drug penetration Zhuyu Juanbi formulae significantly reduced the FACT/ GOG-Ntx score and TNS score in the treatment group. In terms of drug safety, it rarely caused adverse reactions such as grade 3 and 4 leukopenia, and the safety profile was therefore good. Conclusion: The combination of ultrasonic medicine permeating Zhuyu Juanbi formulae and methylcobalamin has been demonstrated to be an effective treatment for peripheral neurotoxicity in patients with PIPN. It has been shown to significantly improve the clinical symptoms of PIPN patients, improve the quality of life of patients, and have a good safety profile.展开更多

However...Diabetic peripheral neuropathy (DPN) is a common and devastating complication of diabetes, for which effective therapies are currently lacking. Disturbed energy status plays a crucial role in DPN pathogenesis. However, the integrated profile of energy metabolism, especially the central carbohydrate metabolism, remains unclear in DPN. Here, we developed a metabolomics approach by targeting 56 metabolites using high-performance ion chromatography-tandem mass spectrometry (HPIC-MS/MS) to illustrate the integrative characteristics of central carbohydrate metabolism in patients with DPN and streptozotocin-induced DPN rats. Furthermore, JinMaiTong (JMT), a traditional Chinese medicine (TCM) formula, was found to be effective for DPN, improving the peripheral neurological function and alleviating the neuropathology of DPN rats even after demyelination and axonal degeneration. JMT ameliorated DPN by regulating the aberrant energy balance and mitochondrial functions, including excessive glycolysis restoration, tricarboxylic acid cycle improvement, and increased adenosine triphosphate (ATP) generation. Bioenergetic profile was aberrant in cultured rat Schwann cells under high-glucose conditions, which was remarkably corrected by JMT treatment. In-vivo and in-vitro studies revealed that these effects of JMT were mainly attributed to the activation of adenosine monophosphate (AMP)-activated protein kinase (AMPK) and downstream peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α). Our results expand the therapeutic framework for DPN and suggest the integrative modulation of energy metabolism using TCMs, such as JMT, as an effective strategy for its treatment.展开更多

It is a syndrome with many different causes. We reviewed the clinical, electrophysi- ological and nerve biopsy findings of 14 patients who suffered from multiple mononeuropathy in our clinic between January 2009 and June 2013. Patients were diagnosed with vasculitic neurop- athy （n = 6）, perineuritis （n = 2）, chronic inflammatory demyelinating polyradiculoneuropathy （n = 2） or Lewis-Sumner syndrome （n = 1） on the basis of clinical features, laboratory data, elec- trophysiological investigations and nerve biopsies. Two patients who were clinically diagnosed with vasculitic neuropathy and one patient who was clinically diagnosed with chronic inflamma- tory demyelinating polyradiculoneuropathy were not confirmed by nerve biopsy. Nerve biopsies confirmed clinical diagnosis in 78.6% of the patients （11/14）. Nerve biopsy pathological diagno- sis is crucial to the etiological diagnosis of multiple mononeuropathy.展开更多
文摘Diabetes,commonly known for its metabolic effects,also critically affects the enteric nervous system(ENS),which is essential in regulating gastrointestinal(GI)motility,secretion,and absorption.The development of diabetes-induced enteric neuropathy can lead to various GI dysfunctions,such as gastroparesis and irregular bowel habits,primarily due to disruptions in the function of neuronal and glial cells within the ENS,as well as oxidative stress and inflammation.This editorial explores the pathophysiological mechanisms underlying the development of enteric neuropathy in diabetic patients.Additionally,it discusses the latest advances in diagnostic approaches,emphasizing the need for early detection and intervention to mitigate GI complications in diabetic individuals.The editorial also reviews current and emerging therapeutic strategies,focusing on pharmacological treatments,dietary management,and potential neuromodulatory interventions.Ultimately,this editorial highlights the necessity of a multidisciplinary approach in managing enteric neuropathy in diabetes,aiming to enhance patient quality of life and address a frequently overlooked complication of this widespread disease.

文摘Background:Bortezomib results in peripheral neuropathy(PN)in approximately 50%of patients,during multiple myeloma(MM)treatment,a complication known as Bortezomib-induced peripheral neuropathy(BIPN).The drug response varies among individuals.Genetic factor may play an important role in BIPN.Methods:A nextgeneration sequencing(NGS)panel containing 1659 targets from 233 genes was used to identify risk variants for developing BIPN in 204 MM patients who received bortezomib therapy.mRNA expression of MTHFR and ALDH1A1 in 62 peripheral blood samples was detected by real-time quantitative PCR(RT-qPCR).Serum homocysteine(Hcy)levels were detected in 40 samples by chemiluminescent microparticle immunoassay(CMIA).Results:Compared with the non-BIPN group(n=89),a total of 8 significantly associated single nucleotide polymorphisms(SNPs)were identified in the BIPN group(n=115):MTHFR(rs1801131,rs1801133,rs17421511),EPHX1(rs1051740),MME(rs2016848),ALDH1A1(rs6151031),HTR7(rs1935349)and CYP2A6(rs8192720).The mRNA expression level of MTHFR in newly diagnosed patients with peripheral neuritis after treatment(NP group)was lower than that of newly diagnosed patients without peripheral neuritis after treatment(NnP group)(1.70±0.77 vs.2.81±0.97,p=0.009).Serum Hcy levels were significantly higher in BIPN group than in non-BIPN group(11.66±1.79μmol/L vs.8.52±3.29μmol/L,p=0.016)and healthy controls(11.66±1.79μmol/L vs.8.55±2.13μmol/L,p≤0.001).Conclusion:CYP2A6,EPHX1,MTHFR,ALDH1A1,HTR7,MME and BIPN are linked in Chinese MM patients.BIPN is more likely to occur in patients with lower MTHFR mRNA expression,which might result in higher serum Hcy levels.
文摘Objective: To observe the clinical efficacy and differences of the Zhuyu Juanbi formula delivered through ultrasound at Zusanli on patients with chemotherapy-induced peripheral neuropathy (CIPN) due to paclitaxel injection. Methods: A total of 72 breast cancer patients with CIPN were randomly divided into two groups. The treatment group (36 cases) was treated with oral methylcobalamin plus ultrasonic medicine permeating Zhuyu Juanbi formulae, while the control group (36 cases) was treated with oral methylcobalamin alone. Following two 2 cycles of continuous treatment, the efficacy of peripheral neurotoxicity, TCM syndrome score, FACT/GOG-Ntx score, total neuropathy score, and safety indicators of gynecological cancer patients were observed in the two groups. Result: In the treatment of CIPN, the addition of ultrasonic medicine permeating Zhuyu Juanbi formulae was more effective than oral methylcobalamin alone in reducing peripheral neurotoxicity and improving the quality of life of patients. The difference between the two groups was statistically significant (P < 0.05), and ultrasound drug penetration Zhuyu Juanbi formulae significantly reduced the FACT/ GOG-Ntx score and TNS score in the treatment group. In terms of drug safety, it rarely caused adverse reactions such as grade 3 and 4 leukopenia, and the safety profile was therefore good.

文摘Diabetic peripheral neuropathy is a common complication of diabetes mellitus.Elucidating the pathophysiological metabolic mechanism impels the generation of ideal therapies.However,existing limited treatments for diabetic peripheral neuropathy expose the urgent need for cell metabolism research.Given the lack of comprehensive understanding of energy metabolism changes and related signaling pathways in diabetic peripheral neuropathy,it is essential to explore energy changes and metabolic changes in diabetic peripheral neuropathy to develop suitable treatment methods.This review summarizes the pathophysiological mechanism of diabetic peripheral neuropathy from the perspective of cellular metabolism and the specific interventions for different metabolic pathways to develop effective treatment methods.Various metabolic mechanisms(e.g.,polyol,hexosamine,protein kinase C pathway)are associated with diabetic peripheral neuropathy,and researchers are looking for more effective treatments through these pathways.
文摘Diabetic peripheral neuropathy(DPN)is one of the strongest risk factors for diabetic foot ulcers(neuropathic ulcerations)and the existing ulcers may further deteriorate due to the damage to sensory neurons.Moreover,the resulting numbness in the limbs causes difficulty in discovering these ulcerations in a short time.DPN is associated with gut microbiota dysbiosis.Traditional Chinese medicine(TCM)compounds such as Shenqi Dihuang Decoction,Huangkui Capsules and Qidi Tangshen Granules can reduce the clinical symptoms of diabetic nephropathy by modulating gut microbiota.The current review discusses whether TCM compounds can reduce the risk of DPN by improving gut microbiota.
文摘Neuromodulation for diabetic peripheral neuropathy represents a significant area of interest in the management of chronic pain associated with this condition.Diabetic peripheral neuropathy,a common complication of diabetes,is characterized by nerve damage due to high blood sugar levels that lead to symptoms,such as pain,tingling,and numbness,primarily in the hands and feet.The aim of this systematic review was to evaluate the efficacy of neuromodulatory techniques as potential therapeutic interventions for patients with diabetic peripheral neuropathy,while also examining recent developments in this domain.The investigation encompassed an array of neuromodulation methods,including frequency rhythmic electrical modulated systems,dorsal root ganglion stimulation,and spinal cord stimulation.This systematic review suggests that neuromodulatory techniques may be useful in the treatment of diabetic peripheral neuropathy.Understanding the advantages of these treatments will enable physicians and other healthcare providers to offer additional options for patients with symptoms refractory to standard pharmacologic treatments.Through these efforts,we may improve quality of life and increase functional capacity in patients suffering from complications related to diabetic neuropathy.
文摘Diabetic corneal neuropathy and diabetic retinopathy are ocular complications occurring in the context of diabetes mellitus.Diabetic corneal neuropathy refers to the progressive damage of corneal nerves.Diabetic retinopathy has traditionally been considered as damage to the retinal microvasculature.However,growing evidence suggests that diabetic retinopathy is a complex neurovascular disorder resulting from dysfunction of the neurovascular unit,which includes both the retinal vascular structures and neural tissues.Diabetic retinopathy is one of the leading causes of blindness and is frequently screened for as part of diabetic ocular screening.However,diabetic corneal neuropathy is commonly overlooked and underdiagnosed,leading to severe ocular surface impairment.Several studies have found that these two conditions tend to occur together,and they share similarities in their pathogenesis pathways,being triggered by a status of chronic hyperglycemia.This review aims to discuss the interconnection between diabetic corneal neuropathy and diabetic retinopathy,whether diabetic corneal neuropathy precedes diabetic retinopathy,as well as the relation between the stage of diabetic retinopathy and the severity of corneal neuropathy.We also endeavor to explore the relevance of a corneal screening in diabetic eyes and the possibility of using corneal nerve measurements to monitor the progression of diabetic retinopathy.

文摘Diabetic peripheral neuropathy (DPN) is a common and devastating complication of diabetes, for which effective therapies are currently lacking. Disturbed energy status plays a crucial role in DPN pathogenesis. However, the integrated profile of energy metabolism, especially the central carbohydrate metabolism, remains unclear in DPN. Here, we developed a metabolomics approach by targeting 56 metabolites using high-performance ion chromatography-tandem mass spectrometry (HPIC-MS/MS) to illustrate the integrative characteristics of central carbohydrate metabolism in patients with DPN and streptozotocin-induced DPN rats. Furthermore, JinMaiTong (JMT), a traditional Chinese medicine (TCM) formula, was found to be effective for DPN, improving the peripheral neurological function and alleviating the neuropathology of DPN rats even after demyelination and axonal degeneration. JMT ameliorated DPN by regulating the aberrant energy balance and mitochondrial functions, including excessive glycolysis restoration, tricarboxylic acid cycle improvement, and increased adenosine triphosphate (ATP) generation. Bioenergetic profile was aberrant in cultured rat Schwann cells under high-glucose conditions, which was remarkably corrected by JMT treatment. In-vivo and in-vitro studies revealed that these effects of JMT were mainly attributed to the activation of adenosine monophosphate (AMP)-activated protein kinase (AMPK) and downstream peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α). Our results expand the therapeutic framework for DPN and suggest the integrative modulation of energy metabolism using TCMs, such as JMT, as an effective strategy for its treatment.

文摘AIM:To observe the changes in corneal subepithelial nerve fibers(CNFs)and Langerhans cells(LCs)in patients with type 2 diabetes using corneal laser confocal microscopy(CLCM).METHODS:A total of 60 patients(64 eyes),including 40 patients with type 2 diabetes(DM group)and 20 subjects without diabetes(control group)were included with CLCM.Neuron J plugin of Image J software were used for quantitative analysis of CNF length(CNFL),CNF density(CNFD),corneal nerve branch fiber density(CNBD),main branch length density,branch length density,corneal nerve fiber tortuosity(NT)score,and LCs density.An independent samples t-test to analyze the variability between the two groups was performed,and Pearson correlation analysis was used to analyze the relationships between CNF and multiple biochemical indicators in the DM group.The predictive power of CNF for type 2 diabetes was assessed using the receiver operating characteristic(ROC)curve.RESULTS:There were significant differences in the CNFL,CNFD,and main branch length density between two groups.The results of Pearson correlation analysis showed a significant negative correlation between CNFD and the duration of diabetes as well as triglyceride levels and total cholesterol,and a significant positive correlation between CNFD and serum albumin.In addition,the NT score showed a positive correlation and urea nitrogen,similar to the positive correlation observed between LC density and glycosylated hemoglobin(HbA1c)levels.CNFD showed the highest area under the curve(AUC of ROC)value,followed by main branch length density and CNFL.The AUC of the ROC curve under the logistic regression model also demonstrated good predictive values.The cut-off values of CNFD,CNFL,and main branch length density for diabetes showed 31.25,18.85,and 12.56,respectively.CONCLUSION:In patients with type 2 diabetes,there is a notable reduction in both CNFL and CNFD.These measurements can be influenced by various blood biochemical factors.However,the compromised nerve fibers can serve as valuable indicators for predicting the onset of type 2 diabetes and also as biomarkers for detecting diabetic neuropathy and its related complications.

文摘Objective This study aimed to develop and test a model for predicting dysthyroid optic neuropathy(DON)based on clinical factors and imaging markers of the optic nerve and cerebrospinal fluid(CSF)in the optic nerve sheath.Methods This retrospective study included patients with thyroid-associated ophthalmopathy(TAO)without DON and patients with TAO accompanied by DON at our hospital.The imaging markers of the optic nerve and CSF in the optic nerve sheath were measured on the water-fat images of each patient and,together with clinical factors,were screened by Least absolute shrinkage and selection operator.Subsequently,we constructed a prediction model using multivariate logistic regression.The accuracy of the model was verified using receiver operating characteristic curve analysis.Results In total,80 orbits from 44 DON patients and 90 orbits from 45 TAO patients were included in our study.Two variables(optic nerve subarachnoid space and the volume of the CSF in the optic nerve sheath)were found to be independent predictive factors and were included in the prediction model.In the development cohort,the mean area under the curve(AUC)was 0.994,with a sensitivity of 0.944,specificity of 0.967,and accuracy of 0.901.Moreover,in the validation cohort,the AUC was 0.960,the sensitivity was 0.889,the specificity was 0.893,and the accuracy was 0.890.Conclusions A combined model was developed using imaging data of the optic nerve and CSF in the optic nerve sheath,serving as a noninvasive potential tool to predict DON.

文摘AIM:To investigate the difference in risk factors between non-arteritic anterior ischaemic optic neuropathy(NAION)and central retinal artery occlusion(CRAO)and develop a predictive diagnostic nomogram.METHODS:The study included 37 patients with monocular NAION,20 with monocular CRAO,and 24 with hypertension.Gender,age,and systemic diseases were recorded.Blood routine,lipids,hemorheology,carotid and brachial artery doppler ultrasound,and echocardiography were collected.The optic disc area,cup area,and cup-to-disc ratio(C/D)of the unaffected eye in the NAION and CRAO group and the right eye in the hypertension group were measured.RESULTS:The carotid artery intimal medial thickness(C-IMT)of the affected side of the CRAO group was thicker(P=0.039)and its flow-mediated dilation(FMD)was lower(P=0.049)than the NAION group.Compared with hypertension patients,NAION patients had higher whole blood reduced viscosity low-shear(WBRV-L)and erythrocyte aggregation index(EAI;P=0.045,0.037),and CRAO patients had higher index of rigidity of erythrocyte(IR)and erythrocyte deformation index(EDI;P=0.004,0.001).The optic cup and the C/D of the NAION group were smaller than the other two groups(P<0.0001).The diagnostic prediction model showed high diagnostic specificity(83.7%)and sensitivity(85.6%),which was highly related to hypertension,the C-IMT of the affected side,FMD,platelet(PLT),EAI,and C/D.CONCLUSION:CRAO patients show thicker C-IMT and worse endothelial function than NAION.NAION and CRAO may be related to abnormal hemorheology.A small cup and small C/D may be involved in NAION.The diagnostic nomogram can be used to preliminarily identify NAION and CRAO.
文摘Despite the advent of relatively reliable modalities of diagnosing diabetic peripheral neuropathy(DPN),such as nerve conduction studies,there is still a knowledge gap about the pathophysiology,and thus limited available in-terventions for symptom control and curtailing disease progression.The pharma-cologic aspect of management is mainly centred on pain control,however,there are several important aspects of DPN such as loss of vibration sense,pressure sense,and proprioception which are associated with risks to lower limb health,which pharmacotherapy does not address.Furthermore,published evidence suggests non-pharmacologic interventions such as glycaemic control through dietary modification and exercise need to be combined with other measures such as psychotherapy,to reach a desired,however modest effect.Acupuncture is emerging as an important treatment modality for several chronic medical conditions including neuropathic and other pain syndromes.In their study published in the World Journal of Diabetes on the potential of acupuncture to reduce DPN symptoms and enhance nerve conduction parameters,Hoerder et al have been able to demonstrate that acupuncture improves sensory function and that this effect is likely sustained two months after treatment cessation.Although previous studies also support these findings,larger multi-center randomized control trials including a sham-controlled arm accounting for a placebo effect are required.Overall,given the satisfactory safety profile and the positive results found in these studies,it is likely that acupuncture may become an important aspect of the repertoire of effective DPN management.
文摘BACKGROUND Hepatitis B rarely leads to demyelinating neuropathy,despite peripheral neuropathy being the first symptom of hepatitis B infection.CASE SUMMARY A 64-year-old man presented with sensorimotor symptoms in multiple peripheral nerves.Serological testing showed that these symptoms were due to hepatitis B.After undergoing treatment involving intravenous immunoglobulin and an antiviral agent,there was a notable improvement in his symptoms.CONCLUSION Although hepatitis B virus(HBV)infection is known to affect hepatocytes,it is crucial to recognize the range of additional manifestations linked to this infection.The connection between long-term HBV infection and demyelinating neuropathy has seldom been documented;hence,prompt diagnostic and treatment are essential.The patient's positive reaction to immunoglobulin seems to be associated with production of the antigen-antibody immune complex.
文摘BACKGROUND Diabetic peripheral neuropathy(DPN)is a debilitating complication of diabetes mellitus with limited available treatment options.Radix Salviae,a traditional Chinese herb,has shown promise in treating DPN,but its therapeutic mech-anisms have not been systematically investigated.AIM Radix Salviae(Danshen in pinin),a traditional Chinese medicine(TCM),is widely used to treat DPN in China.However,the mechanism through which Radix Salviae treats DPN remains unclear.Therefore,we aimed to explore the mechanism of action of Radix Salviae against DPN using network pharmacology.METHODS The active ingredients and target genes of Radix Salviae were screened using the TCM pharmacology database and analysis platform.The genes associated with DPN were obtained from the Gene Cards and OMIM databases,a drug-com-position-target-disease network was constructed,and a protein–protein inter-action network was subsequently constructed to screen the main targets.Gene Ontology(GO)functional annotation and pathway enrichment analysis were performed via the Kyoto Encyclopedia of Genes and Genomes(KEGG)using Bioconductor.RESULTS A total of 56 effective components,108 targets and 4581 DPN-related target genes of Radix Salviae were screened.Intervention with Radix Salviae for DPN mainly involved 81 target genes.The top 30 major targets were selected for enrichment analysis of GO and KEGG pathways.CONCLUSION These results suggested that Radix Salviae could treat DPN by regulating the AGE-RAGE signaling pathway and the PI3K-Akt signaling pathway.Therefore,Danshen may affect DPN by regulating inflammation and apoptosis.

文摘BACKGROUND Diabetic sensorimotor polyneuropathy is an important risk factor for foot ulceration and amputation.Thus,patients with diabetes should be screened for this disorder according to local guidelines.An obstacle to the diagnosis of this disease may be the lack of unified diagnostic criteria due to the lack of properly validated scales used for assessment.AIM To validate both sections(A and B)of the Michigan Neuropathy Screening Instrument(MNSI)in Polish(PL)patients with diabetes.METHODS A cross-sectional study using a test(A1,B1)and re-test(A2,B2)formula was performed in 80 patients with diabetes.The gold standard used for neuropathy detection was a nerve conduction study(NCS)which was performed in all participants.Reliability of the MNSI-PL was assessed using the Cronbach’s alpha,Kuder-Richardson formula 20(KR-20),split-half reliability,the Gottman split-half tests,and correlation between first and second half was accessed.Stability was assessed using an intraclass correlation coefficient(ICC).For external validation,we used simple linear correlation,binomial regression,and agreement between two different tools using a Bland-Altman plot analysis.RESULTS The scale was internally consistent(Cronbach’s alpha for the full scale:0.81 for A and 0.87 for B).MNSI-PL scores in test/retest showed high stability(ICC=0.73 for A and ICC=0.97 for B).The statistically important correlations between MNSI-PL and NCS were found for B1,B2,and A1(P<0.005).The cut-off points of≥3 for section A(sensitivity of 90%-100%;specificity of 33%-40%)and≥2 for section B(sensitivity of 81%-84%;specificity of 60%-70%)were obtained during neuropathy detection.CONCLUSION The MNSI-PL is a reliable and valid instrument in screening for diabetic neuropathy.

文摘BACKGROUND Neuropathy of the common peroneal nerve caused by compression by a fabella is an extremely rare form of compression neuropathy.Involving both the superficial and deep peroneal nerves,it usually manifests as either impaired sensation from the lower lateral leg to the top of the foot or drop foot,or as a combination of both.CASE SUMMARY We report the case of a 58-year-old Asian female who presented with inversion of the right foot during the stance phase of gait without sensory complaints related to the lower leg.Electrodiagnostic testing revealed the neuropathy of the common peroneal nerve at the level of the knee,exclusively affecting the muscular branch of the superficial peroneal nerve.A neuromuscular ultrasound disclosed swelling of the right common peroneal nerve just before it crossed over a large fabella as well as atrophy and fatty infiltration of the right peroneus longus and peroneus brevis muscles.Surgical excision of the fabella and neurolysis were performed.Subsequently,the strength of the right foot evertors improved,but the unsteady gait with occasional falls persisted for nine months after the surgery.Therefore,another procedure was performed to transfer the split posterior tibialis tendon to the peroneus brevis in order to correct the gait.CONCLUSION This is the first case of neuropathy of the common peroneal nerve caused by compression by a fabella affecting exclusively the muscular branch of the superficial peroneal nerve.Clinicians should be aware of this unusual peripheral neuropathy while evaluating and treating patients with gait disturbance.
文摘Multiple mononeuropathy is an unusual form of peripheral neuropathy involving two or more nerve trunks. It is a syndrome with many different causes. We reviewed the clinical, electrophysi- ological and nerve biopsy findings of 14 patients who suffered from multiple mononeuropathy in our clinic between January 2009 and June 2013. Patients were diagnosed with vasculitic neurop- athy （n = 6）, perineuritis （n = 2）, chronic inflammatory demyelinating polyradiculoneuropathy （n = 2） or Lewis-Sumner syndrome （n = 1） on the basis of clinical features, laboratory data, elec- trophysiological investigations and nerve biopsies. Two patients who were clinically diagnosed with vasculitic neuropathy and one patient who was clinically diagnosed with chronic inflamma- tory demyelinating polyradiculoneuropathy were not confirmed by nerve biopsy. Nerve biopsies confirmed clinical diagnosis in 78.6% of the patients （11/14）. Nerve biopsy pathological diagno- sis is crucial to the etiological diagnosis of multiple mononeuropathy.
