Abstract Background: This study explored the correlation between pancreatic islet α cell function, as reflected by the plasma glucagon levels, and Diabetic Peripheral Neuropathy (DPN) in patients with Type 2 Diabetes Mellitus (T2DM). Methods: A total of 358 patients with T2DM were retrospectively enrolled in this study and divided into the Non-DPN (NDPN) group (n = 220) and the DPN group (n = 138). All patients underwent an oral glucose tolerance test to detect levels of blood glucose, insulin and glucagon, and the Area Under the Curve (AUC) for Glucagon (AUCglu) was used to estimate the overall glucagon level. The Peripheral Nerve Conduction Velocity (PNCV), Amplitude (PNCA) and Latency (PNCL) were obtained with electromyography, and their Z scores were calculated. Results: There were significant differences regarding the age, disease duration, serum levels of alanine aminotransferase, aspartate aminotransferase, urea nitrogen, high-density lipoprotein, and 2h-C peptide between these two groups (p < 0.05). The NDPN group had higher glucagon levels at 30, 60 and 120 min and AUCglu (p < 0.05). The Z-scores of PNCV and PNCA showed an increasing trend (p < 0.05), while the Z-score of PNCL showed a decreasing trend (p < 0.05). The glucagon levels were positively correlated with PNCV and PNCA, but negatively correlated with PNCL, with Gluca30min having the strongest correlation (p < 0.05). Gluca30min was independently related to PNCV, PNCL, PNCA and DPN, respectively (p < 0.05). The function of pancreatic α islet cells, as reflected by the plasma glucagon level, is closely related to the occurrence of DPN in T2DM patients. Conclusion: Gluca30min may be a potentially valuable independent predictor for the occurrence of DPN.

Objectives: Cerebral palsy (CP) is a motor impairment syndrome leading to disorders of movement and posture. Screening of electrophysiological parameters Hoffman reflex (H-reflex and nerve conduction velocities) becomes a necessary for the early detection and management of the disease. The study aimed to assess the various electrophysiological parameters of nerve conduction velocity in CP and age-matched normal children. Matrials and Methods: The present cross-sectional study was performed between children suffering from CP and healthy control. A total of 27 children of 12–24 months of age of either sex were examined. Among them, six children were normal (with age match), seven were diagnosed with spastic CP and remaining 14 children were diagnosed with hypotonic CP The electrophysiological parameters were recorded in the right lower limb (posterior tibial nerve-soleus muscle) of all children. Results: In electrophysiological parameters, H-reflex latency in secs values was significantly decreased in all CP children. The maximum amplitudes of reflexly excitable motor neurons (Hmax) (mV) and Hmax/maximum amplitude of motor response ratio in the gastrocnemius-soleus muscle were significantly increased in spastic CPas compared to control. H-reflex conduction velocity (HRCV) was significantly higher than motor nerve conduction velocity (MNCV) in hypotonic CP children. Conclusion: The electrophysiological parameters were altered in spastic CP children. The electrophysiological parameters in hypotonic CP were within range, indicating they did not suppress the neuronal motor pool. However, HRCV was significantly more than MNCV in hypotonic CP, suggesting some myelination process defect/white matter injury in motor neurons. We concluded that the electrophysiological parameters of the nerve conduction study are a reliable test for the assessment of tone of muscles in children. Thus, it may help in the early initiation of the treatment and therapies in CP children.

Background: With the advancement in digital world, but smart phone usage has increased among all age groups but youngsters are involved in heavy gaming on smart phones which has led to increased risk of ill-effects especially on eyes and hands. Aim and Objectives: The study was designed to study the ill-effects of excessive usage if smart phones on peripheral nerves of hands especially of dominant hand among young adults. Materials and Methods: Nerve conduction study was performed on 100 young adults who were divided into three groups on the basis of mobile usage time. Nerve conduction velocities as well as distal latencies of motor and sensory nerves of the dominant hand were measured among different groups. Results: One-way ANOVA test was applied to study the results among different groups. Although no significant difference in conduction velocity or latency was observed in motor or sensory nerves among three groups, Ulnar sensory conduction velocity has been found to be slow as well as distal latency was found to be prolonged in third group with heavy usage of smart phones as compared to other groups. Conclusion: The reason for the above results could be due to less usage time in hours as well as in years due to which no significance differences were observed in conduction velocity/distal latency in our study. Hence, further studies are suggested with more sample size and more usage time in terms of years as well as in hours.

Objective:To analyze the characteristics of nerve injury in patients with diabetic peripheral neuropathy (DPN) and explore the diagnostic value of current perception threshold (CPT) and nerve conduction velocity (NCV) for DPN.Methods:One hundred and thirty-six DPN patients admitted to Beijing Puren Hospital from June 2017 to December 2019 were selected, and 130 diabetic non-DPN patients admitted during the same period were used as controls. All the subjects were tested by CPT and NCV. Among them, the detection of NCV included sensory nerve conduction velocity (SCV) and motor nerve conduction velocity (MCV). Statistical analysis was performed on the relevant indicators of the two groups of subjects.Results:The CPT values of the upper limb median nerve and ulnar nerve at 2 000 Hz, 250 Hz, and 5 Hz, the superficial peroneal nerves at 250 Hz, and 5 Hz, and the CPT values of the sural nerve at 2 000 Hz and 250 Hz were higher than those of non-DPN patients, DPN injury mainly occurred in myelinated nerve fibers in the lower extremities [60.29%(82/136)], and the difference were statistically significant ( P<0.05). The SCV and MCV of the median nerve, ulnar nerve, and common peroneal nerve in the DPN group were lower than those in the non-DPN group, the SCV abnormal rate was higher than the MCV: 55.88%(76/136) vs. 37.50%(51/136); 58.82%(80/136) vs. 41.18% (56/136); 67.65%(92/136) vs. 50.00%(68/136), and the differences were statistically significant ( P<0.05). The area under the predictive value curve (AUC) of CPT for DPN was 0.815 (95% CI 0.735 ~ 0.895). The AUC of NCV for DPN was 0.875 (95% CI 0.813 ~ 0.944). The AUC of CPT and NCV for DPN was 0.923 (95% CI 0.876 ~ 0.970). Conclusions:DPT patients have abnormal CPT and NCV, and nerve damage occurs mostly in myelinated nerve fibers and SCV. Diagnosing DPN by combining CPT and NCV is helpful to improve the detection rate of DPN.

Background: Leprosy and the associated scourge have affected humanity for thousands of years. One of the most debilitating consequences of leprosy is peripheral neuropathy. Nerve Conduction Velocity study provides us with a non-invasive modality to assess peripheral nerve involvement in leprosy.Methods: With this in mind, a cross-sectional observational study was conducted including 30 leprosy patients as "Cases" and 30 age-matched healthy subjects, not suffering from any kind of neurological disorders, as "Controls". Using a digital electromyography machine, the Latency, Amplitude and Conduction Velocities of Motor and Sensory fibres of Ulnar and Median nerves were recorded. The results were compared among controls and cases using suitable statistical tests (descriptive statistics and significance testing using unpaired t-test).Results: In this study, with regard to Sensory Nerve conduction Velocity (SNCV), statistically very significant difference was noted in case of right (p 0.0011) and left (p 0.0037) ulnar nerves among controls and cases. The difference in the amplitude of Motor Action potential (MAP) with regard to right median nerve, among cases and controls, was also statistically significant (p 0.0127). Further the amplitude of Sensory Nerve Action Potential (SNAP) values were higher among cases compared to controls.Conclusions: As such, the findings of this study (and which is also corroborated by many previous studies) lead us to the conclusion that NCV studies can detect lepromatous neuropathy much before the emergence of frank clinical signs and this type of neuropathy is predominantly demyelinating in nature with occasional axonal loss.

Abstract Objective: The effects of vitamin D on the central and peripheral nervous system continue to be investigated today. In the present study, we aimed to evaluate pain and electrophysiologic response in patients with carpal tunnel syndrome (CTS) who have undergone replacement therapy due to vitamin D deficiency. Methods: Fifty female patients diagnosed with mild and moderate CTS and accompanied by vitamin D deficiency were included in this study. Nerve conduction study (NCS) was performed before and after vitamin D replacement, and the patient's pain was evaluated with Visual Analogue Scale (VAS). Results: When NCS were compared before and after treatment, there was a statistically significant improvement in the median distal sensory onset latency (DSOL) and sensory conduction velocity (CV) and motor distal latencies (DML) values (p=0.001; p<0.001; p=0.001, respectively). At the same time, there was a decrease in the VAS values in patients (p<0.001). When the two groups were compared there was an improvement in DSOL and sensory CV in both groups, but in DML only in moderate CTS group. Conclusion: In this study, it was shown that mild and moderate CTS patients had an improvement in pain and electrophysiological parameters after vitamin D replacement. Replacing vitamin D in early stages of CTS may be beneficial.
Resumo Objetivo: Os efeitos da vitamina D no sistema nervoso central e periférico continuam sendo investigados atualmente. Neste estudo, objetivamos avaliar a dor e a resposta eletrofisiológica em pacientes com síndrome do túnel do carpo (STC) submetidos a terapia de reposição devido à deficiência de vitamina D. Métodos: Cinquenta pacientes do sexo feminino diagnosticadas com STC leve e moderada e acompanhadas de deficiência de vitamina D foram incluídas neste estudo. O estudo da condução nervosa (ECN) foi realizado antes e após a reposição da vitamina D, e a dor do paciente foi avaliada com a Escala Visual Analógica (EVA). Resultados: Quando a ECN foi comparada antes e após o tratamento, houve uma melhora estatisticamente significativa na latência mediana do início sensorial distal (DSOL) e nos valores de velocidade de condução sensorial (VC) e latência distal motora (LDM) (p=0,001; p<0,001; p=0,001, respectivamente). Ao mesmo tempo, houve uma diminuição dos valores da EVA nos pacientes (p<0,001). Quando os dois grupos foram comparados, houve uma melhora no DSOL e no VC sensorial em ambos, mas no LDM apenas no grupo STC moderado. Conclusão: Neste estudo, foi demonstrado que pacientes com STC leve e moderada apresentaram melhora da dor e parâmetros eletrofisiológicos após a reposição de vitamina D. A substituição da vitamina D nos estágios iniciais da STC pode ser benéfica.

Objective To analyze the characteristics of nerve damage in diabetic peripheral neuropathy by ultrasound and neuroelectrophysiological techniques and provide a basis for early diagnosis and treatment of diabetic peripheral neuropathy. Methods From January 2016 to May 2018, 225 patients with type 2 diabetes admitted to the hospital were divided into DPN group (110 cases) and non-diabetic peripheral neuropathy (NDPN) group (115 cases),and 120 healthy volunteers were as controls. Ultrasound and nerve conduction velocity(NCV) were used to analyze the characteristics of nerve damage in diabetic peripheral neuropathy(DPN). Results Among the three study groups, the sensory nerves conduction velocity and motor nerves conduction velocity of the ulnar nerve, median nerve, and common peroneal nerve were significantly reduced in the DPN group. But in the same group,the ulnar nerve, median nerve, and common peroneal nerve cross-sectional area (CSA) was significantly increased [(8.68 ± 1.89) mm2 vs. (6.79 ± 1.69) and (5.82 ± 1.57) mm2, (10.59 ± 1.82) mm2 vs. (7.98 ± 1.97) and (7.25 ± 1.71) mm2, (21.24 ± 2.53 )mm2 vs. (16.54 ± 2.49) and (15.40 ± 2.20) mm2]. In the measurement of sensory nerve conduction velocity, the abnormalities of ulnar nerve, median nerve and common peroneal nerve were significantly higher than thoseof motor nerve [34.54%(38/110) vs. 18.18%(20/110), 36.36% (40/110)vs. 20.90% (23/110), 52.72% (58/110) vs. 20.00% (22/110)]. In ultrasound and SCV, the proportion of ulnar nerve and median nerve injury was higher in patients aged 45 years or older or patients over 10 years of course (P<0.05). The proportion of median nerve injury was higher in patients with larger MAGE (P < 0.05). In the abnormal performance of ultrasound: the proportion of abnormal ulnar nerve, median nerve and common peroneal nerve in patients with large MAGE was significantly higher than that in patients with small MAGE (P<0.05); the results of ultrasound measurement of CSA showed that the ulnar nerve, median nerve and common peroneal nerve thickening were more obvious in patients with MAGE>4 mmol/L. Conclusions DPN affects sensory nerves first, and the proportion of injury is significantly higher than that of motor nerves; lower limb nerves are more susceptible to damage, compared with upper limb nerves; patients aged 45 years or older or patients with course over 10 years have a higher proportion of ulnar nerve and median nerve damage; patients with larger MAGE (>4 mmol/L) have a higher proportion of median nerve damage. The characteristics above can provide an effective basis for the prevention, diagnosis and treatment of DPN.

OBJECTIVE: To investigate the therapeutic effect of electroacupuncture on peripheral nerve damage induced by 1-bromopropane( 1-BP) exposure.METHODS: A total of 25 specific pathogen free healthy adult male Wistar rats were randomly divided into blank control group( n = 5),model control group( n = 10),and electroacupuncture treatment( EA) group( n = 10).Rats in the blank control group were not exposed to 1-BP and treated with electroacupuncture.The rats in model control group and EA group were placed in a dynamic inhalation exposure cabinet with 1-BP at concentration of 5 000 mg/m~3.The rats were continuously exposed to 1-BP 8 hours per day,5 days a week,for 4 weeks.At the 3 rd day after the end of the exposure,the EA group was treated with electroacupuncture on“Zu sanli”and“Huantiao”points for 4 courses.Each course included 20 minutes each time,once per day for 7 consecutive days.The body weight,the motor nerve conduction velocity( MCV) and sense nerve conduction velocity( SCV) of sciatic nerves on both posterior limbs of the rats were measured.RESULTS: During the course of 1-BP exposure,the rats in the EA and model control group showed reduction of eating,drinking and activities,limited autonomic activities and their hind limbs dragged.The MCV and SCV of posterior limb sciatic nerve of rats in the model control group were slower than that of the control group at the 4 th,6th and 8th week and the 0 week of the same group( P < 0.05).The MCV and SCV of posterior limb sciatic nerve of rats in the EA group improved with the increase of treatment time( P < 0.05),and those at the 6th and 8th weeks of the experiment( corresponding to the 2nd and 4th week after treatment) were faster than that of the model control group at the same time( P < 0.05).The SCV of the posterior limb sciatic nerve in the EA group recovered to normal level 4 weeks after treatment compared with the blank control group( P < 0.05).CONCLUSION: Electroacupuncture treatment can promote the recovery of peripheral nerve damage in rats with 1-BP poisoning.
Résumé
To investigate the influence of Angelica Four Inverse Decoction on diabetic peripheral neuropathy (DPN) nerve conduction velocity and advanced glycation end products (AEGs), Cystatin C (Cys-C) and homocysteine (Hcy) levels, 78 cases of DPN patients admitted in our hospital from March 2015 to January 2017 were selected and divided into two groups by random number table method. The two groups adopted the same basic treatment, on the basis of which, the control group was added mecobalamin tablets treatment, while the observation group was given Angelica Four Inverse Decoction. The curative effect of Chinese medicine syndrome, the scores of toronto clinical scoring system (TCSS), nerve conduction velocity and the change of serum AEGs, Cys-C and Hcy levels before and after treatment were recorded and compared between the two groups and then the safety of medicine were evaluated between the two groups. 4 weeks after the treatment, the total effective rate of the observation group was 89.7％, significantly higher than 71.8％ of the control group (P ＜ 0.05) . Compared with those before receiving treatment, the SNCV and MNCV values of the common peroneal nerve and median nerve both significantly increased in the two groups 4 weeks after the treatment (P ＜ 0.01); the improvement of nerve conduction velocity of the observation group was significantly better than that of the control group (P ＜ 0.01) . 4 weeks after the treatment, TCSS score and serum AEGs, Cys-C, Hcy levels were all significantly lower than those before receiving the treatment in the two groups (P ＜ 0.01); compared with that of the control group in the same time period, the improvement effect of TCSS score and serum AEGs, Cys-C, Hcy levels were more significant in the observation group 4 weeks after the treatment (P ＜ 0.01) . There were no obvious adverse reactions in the two groups. As a result, Angelica Four Inverse Decoction applied to DPN patients can more effectively relieve clinical symptoms and signs, improve nerve conduction velocity, reduce the level of AEGs, and improve microcirculation with remarkable curative effect and high safety.
