DM chronic complications are major causes of morbidity and mortality, among which diabetic neuropathy (DN) stands out, affecting 30% - 50% of DM patients. An appropriate medical approach, involving anamnesis and thorough clinical examination, is extremely important for the early diagnosis of DN and, therefore, to the prevention of its complications, including the amputation of limbs. Despite of the importance of DN prevention and treatment, in order to provide improved quality of life and longevity to DM patients, current therapeutic options are very limited with respect to both symptom control and as effective disease therapies. Intensive glucose control is extremely important in order to prevent and avoid the progression of DN, as demonstrated in two large multicenter studies involving patients with type 1 DM, the DCCT (Diabetes Control and Complications Trial) and the EDIC (Epidemiology of Diabetes Interventions and Complications).展开更多

We also investigated the factors associated with the development of s DPN and compared factors between the sD PN and confirmed DPN(cDPN). This cross-sectional study involved 240 T2DM patients who were successively admitted to the endocrinology wards of Wuhan Union Hospital over the period of January to December 2014. Data on the medical history, physical and laboratory examinations were collected. DPN was diagnosed using NCS. One-way ANOVA with least significant difference(LSD) analysis or chi-square tests was used to compare parameters among DNP-free, s DPN and c DPN patients. Independent factors associated with s DPN were determined using logistic regression. The results showed that 50.8% of the participants had DPN, and among them, 17.1% had sDPN. sDPN showed significant independent associations with age, height, HbA1c, presence of atherosclerosis and diabetic retinopathy. Patients with DPN differed significantly from those without DPN with respect to age, duration of disease(DOD), HbA1c, presence of atherosclerosis, diabetic retinopathy, nephropathy and hypertension. Patients with cDPN, relative to those with sDPN, had significantly longer DOD and higher prevalence of peripheral artery disease(PAD) and coronary artery disease(CAD). Our study suggests that a significant number of T2DM patients are affected by s DPN, and the development of this condition is associated with advanced age, tall stature, poor glycaemic control, presence of diabetic retinopathy and atherosclerosis. On the other hand, patients with cDPN tend to have a longer DOD and are more likely to suffer from PAD and CAD.展开更多

The reported prevalence of diabetic foot ulceration in Pakistan is between 4% and 10%, with the amputation rate of 8% - 21%. Peripheral neuropathy and vasculopathy are main underlying cause of diabetic foot ulcers. Methodology: It was a cross-sectional non-interventional cohort study where all newly diagnosed treatment naïve type 2 diabetic patients were enrolled. Peripheral neuropathy and vasculopathy were detected by Michigan neuropathy screening instrument (MNSI) and ankle brachial index (ABI) respectively. Risk factors for peripheral neuropathy and vasculopathy were determined by univariate and multivariate logistic regression analysis. Statistical significance was considered with P value of Result: Fifty seven patients (37.7%) had early neuropathy with MNSI score of 3.3 ± 0.4. Thirty seven patients (20.6%) had vasculopathy with ABI score of 0.76 ± 0.11. Age (Odd ratio 1.07 (1.02 - 1.11), p 0.003), duration of symptoms (Odd ratio 1.11 95% CI: 1.05 - 1.17, p ≤ 0.001), high HbA1C % (Odd ratio 1.94 95% CI: 1.54 - 2.45, P ≤ 0.001), albumin creatinine ratio (Odd ratio 1.01, 95% CI: 1.00 - 1.01, P ≤ 0.001 ) and cholesterol level (Odd ratio 1.01 95% CI: 1.01 - 1.02, p = 0.001) were found as risk factors for early neuropathy and vasculopathy. Conclusion: Peripheral neuropathy and vasculopathy are frequently reported complications among newly diagnosed treatment naïve patients of type 2 DM. Age, duration of symptoms prior to diagnosis, metabolic parameters like raised HbA1C, hyperlipidemia and spot random albumin creatinine ratio are found to be risk factors for both peripheral neuropathy and vasculopathy.展开更多

Vitamin Bi and methyl-vitamin BI2 improve microcirculation to peripheral nerve tissue and promote neurotrophy. OBJECTIVE： To observe motor nerve and sensory nerve conduction velocity in patients with diabetic peripheral neuropathy, prior to and after treatment with prostaglandin El, vitamin B I and different doses of vitamin B 12. DESIGN, TIME AND SETTING： Randomized, controlled experiment, performed at the Department of Neurology, Beijing Hantian Central Hospital, between February 2002 and September 2007. PARTICIPANTS： A total of 122 patients with type 2 diabetic peripheral neuropathy; 73 males and 49 females were included. All patients met the diagnostic criteria of diabetes mellitus, as determined by the World Health Organization in 1999 and 2006, and also the diagnostic criteria of diabetic peripheral neuropathy. For each subject, conduction disorders in the median nerve and in the common peroneal nerve were observed using electromyogram. Also, after diet and drug treatment, the blood glucose level of subjects was observed to be at a satisfactory level for more than two weeks, and the symptoms of diabetic peripheral neuropathy were not alleviated. METHODS： All patients were randomly divided into the following three groups. A control group （n = 40）, in which, 100 mg vitamin B1 and 500 μg vitamin BI2 were intramuscularly injected. A vitamin B12 low-dose treated group （ n = 42）, in which 10 μ g prostaglandin E1 in 250 mL physiological saline was intravenously injected once a day and 100 mg vitamin BI and 500 11 g vitamin BI2 was intramuscularly injected once a day. Lastly, a vitamin B12 high-dose treated group （n = 40）, in which administration was the same as in the vitamin B12 low-dose treated group, except that 500 11 g vitamin BI2 was replaced by 1mg vitamin B12. Administration was performed for four weeks for each group. MAIN OUTCOME MEASURES： The motor nerve and sensory nerve conduction velocity of the median nerve and the common peroneal nerve were determined using an electromyogram electronic stimulator （Neuropack-11, Nihon Kohden, Japan）. RESULTS： The motor nerve and sensory nerve conduction velocities of the median nerve and the common peroneal nerve were significantly faster after treatment compared to before treatment in all 3 groups （P 〈 0.05q）.01）. Compared with the control group, the motor nerve and sensory nerve conduction velocities were significantly faster in the vitamin B12 low-dose treated group and in the vitamin B12 high-dose treated group （P 〈 0.01）. The motor nerve and sensory nerve conduction velocities were significantly faster in the vitamin B12 high-dose treated group compared to the vitamin B12 low-dose treated group （P 〈 0.05）. CONCLUSION： Prostaglandin E1, in conjunction with vitamin B12, can improve neural functional states and speed up peripheral motor nerve and sensory nerve conduction velocity in diabetic peripheral neuropathy. In addition, better effects are achieved using prostaglandin E1 in conjunction with high doses of vitamin B 12.展开更多

Mice defined as diabetic in this model were then treated with 1.80, 5.39 or 8.98 m L/kg of Cerebrolysin via intraperitoneal injections for 10 consecutive days. Our results demonstrated that the number, diameter and area of myelinated nerve fibers increased in the sciatic nerves of these mice after administration of Cerebrolysin. The results of several behavioral tests showed that Cerebrolysin dose-dependently increased the slope angle in the inclined plane test（indicating an improved ability to maintain body position）, prolonged tail-flick latency and foot-licking time（indicating enhanced sensitivity to thermal and chemical pain, respectively, and reduced pain thresholds）, and increased an index of sciatic nerve function in diabetic mice compared with those behavioral results in untreated diabetic mice. Taken together, the anatomical and functional results suggest that Cerebrolysin ameliorated peripheral neuropathy in a mouse model of type 2 diabetes mellitus.展开更多

Fifteen patients were received large dose methylcobalamin injection for two weeks as treatment group, another eleven patients were received muscular injection VitB1 100mg/ d, VitB12 500ug/ d for two weeks as control group. After 2 weeks treatment the subjective symptoms and signs were significantly improved with a total effective rate of 82.9% in the treatment group however the effective rate only has 52.0% in the control group. The result has obvious difference in statistics nerve MCV in median common peroneal nerve, SCV in median and superficial peroneal nerve were improved significantly in the treatment group and no such changes were observed in the control group. So, large dose methylcobalamin is an effective and safe agent for treatment of diabetic peripheral neuropathy.展开更多

Here, we se- quenced the coding region of the angiogenin gene in genomic DNA from 207 patients with type 2 diabetes mellitus （129 diabetic peripheral neuropathy patients and 78 diabetic non-neuropathy pa- tients） and 268 healthy controls. All subjects were from the Han population of northern China. No mutations were found. We then compared the genotype and allele frequencies of the angiogenin synonymous single nucleotide polymorphism rs11701 between the diabetic peripheral neuropathy patients and controls, and between the diabetic neuropathy and non-neuropathy patients, using a case-control design. We detected no statistically significant genetic associations. Angiogenin may not be associated with genetic susceptibility to diabetic peripheral neuropathy in the Han population of northern China.展开更多

The aim of the study is to determine prevalence and determinants of diabetic neuropathy in diabetic children. Material& Methods: This is a cross sectional study conducted on 50 children having Type I diabetes mellitus for more than year presented to Pediatric Neurology and Endocrinology Outpatient Clinics, Sohag University Hospital, Sohag, Egypt, during one year duration (2017). Children were subjected to detailed neurological examination and electrophysiologic studies in addition to recording of socio demographic and laboratory findings with special regard to level of HbA1c. Results: The mean age of the studied children was 10.5 ± 0.3 years ranging from 5 to 18 years. 22 cases (44%) were younger than 10 years, 27 children (54%) were females. DPN was diagnosed in 12% of the studied children. No significant relation was found as regard age, gender, family history, consanguinity and duration of the diseases. Significant association was found between the HbA1c level and development of DPN in the studied children. Conclusion: Based on the results of this study, 12% of the studied diabetic children had DPN of whom more than 16% had subclinical neuropathy indicating the need for annual screening of neuropathy using Nerve Conduction Study. Moreover strict glycaemic control is needed to prevent rapid development of diabetic among these children.展开更多

Hypomagnesaemia accelerates the rate of diabetic complications. Objective: To analyze the association of serum magnesium (Mg) in Type 2 Diabetes Mellitus with and without complication of peripheral neuropathy. Design: A cross sectional study. Setting: This research was carried out in medicine department, Peoples Medical College Hospital Nawabshah from May 2016-April 2017. Sample Size: Total 271 patients of both genders with Type 2 DM with and without peripheral neuropathy, each group after fulfilling the selection criteria were included. Material and Methods: After a short-lived consultation, the subjects were categorized for variable analyses like sex, age, Type 2 Diabetes Mellitus with and without peripheral neuropathy, duration of diabetes mellitus and presence of hypomagnesaemia. Clinical examination with monofilament was applied for diagnosis of peripheral neuropathy. Blood samples for magnesium analysis were collected in fasting condition. Results: In 271 diagnosed patients of Type 2 diabetes mellitus, 180 male and 91 were females. Peripheral neuropathy was observed in 136 subjects out of them 94 males and 42 were females. While 135 were without peripheral neuropathy out of them 86 males and 49 were females. Normal magnesium was seen in 119 (43.91%) and low magnesium was present in 152 (56.09%) patients overall. A decreased serum level of magnesium was observed in 56.09% diabetic subjects with peripheral neuropathy and 50% subjects with diabetes without peripheral neuropathy. Conclusion: Frequency of hypomagnesaemia is common in subjects with in Type 2 DM with and without peripheral neuropathy.展开更多

Traditional Chinese medicine nursing, which is development on the basis of traditional Chinese medicine （TCM） theory, uses not only acupuncture, acupoint application and other treatments but also cares for the patient＇s diet and emotions in order to promote the recovery of skin and nerve endings in patients with DPN. Vast amounts of studies have explored the efficacies of various TCM nursing techniques in managing DPN, however, the article, which comprehensively documented these TCM nursing techniques in DNP patients, cannot be cap- tured. In the present article, we summarized the latest findings of TCM research on DPN in recent years in order to provide a reference for DPN.展开更多

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Diabetes mellitus (DM) is considered a major public health problem because of its high prevalence and progressive increase of incidence. DM chronic complications are major causes of morbidity and mortality, among which diabetic neuropathy (DN) stands out, affecting 30% - 50% of DM patients. An appropriate medical approach, involving anamnesis and thorough clinical examination, is extremely important for the early diagnosis of DN and, therefore, to the prevention of its complications, including the amputation of limbs. Despite of the importance of DN prevention and treatment, in order to provide improved quality of life and longevity to DM patients, current therapeutic options are very limited with respect to both symptom control and as effective disease therapies. Intensive glucose control is extremely important in order to prevent and avoid the progression of DN, as demonstrated in two large multicenter studies involving patients with type 1 DM, the DCCT (Diabetes Control and Complications Trial) and the EDIC (Epidemiology of Diabetes Interventions and Complications).

文摘This study determined the prevalence of diabetic peripheral neuropathy(DPN) and subclinical DPN(s DPN) in patients with type 2 diabetes mellitus(T2DM) using nerve conduction study(NCS) as a diagnostic tool. We also investigated the factors associated with the development of s DPN and compared factors between the sD PN and confirmed DPN(cDPN). This cross-sectional study involved 240 T2DM patients who were successively admitted to the endocrinology wards of Wuhan Union Hospital over the period of January to December 2014. Data on the medical history, physical and laboratory examinations were collected. DPN was diagnosed using NCS. One-way ANOVA with least significant difference(LSD) analysis or chi-square tests was used to compare parameters among DNP-free, s DPN and c DPN patients. Independent factors associated with s DPN were determined using logistic regression. The results showed that 50.8% of the participants had DPN, and among them, 17.1% had sDPN. sDPN showed significant independent associations with age, height, HbA1c, presence of atherosclerosis and diabetic retinopathy. Patients with DPN differed significantly from those without DPN with respect to age, duration of disease(DOD), HbA1c, presence of atherosclerosis, diabetic retinopathy, nephropathy and hypertension. Patients with cDPN, relative to those with sDPN, had significantly longer DOD and higher prevalence of peripheral artery disease(PAD) and coronary artery disease(CAD). Our study suggests that a significant number of T2DM patients are affected by s DPN, and the development of this condition is associated with advanced age, tall stature, poor glycaemic control, presence of diabetic retinopathy and atherosclerosis. On the other hand, patients with cDPN tend to have a longer DOD and are more likely to suffer from PAD and CAD.
文摘Background: The prevalence of diabetes in Pakistan is 11.45%. The reported prevalence of diabetic foot ulceration in Pakistan is between 4% and 10%, with the amputation rate of 8% - 21%. Peripheral neuropathy and vasculopathy are main underlying cause of diabetic foot ulcers. Methodology: It was a cross-sectional non-interventional cohort study where all newly diagnosed treatment naïve type 2 diabetic patients were enrolled. Peripheral neuropathy and vasculopathy were detected by Michigan neuropathy screening instrument (MNSI) and ankle brachial index (ABI) respectively. Risk factors for peripheral neuropathy and vasculopathy were determined by univariate and multivariate logistic regression analysis. Statistical significance was considered with P value of Result: Fifty seven patients (37.7%) had early neuropathy with MNSI score of 3.3 ± 0.4. Thirty seven patients (20.6%) had vasculopathy with ABI score of 0.76 ± 0.11. Age (Odd ratio 1.07 (1.02 - 1.11), p 0.003), duration of symptoms (Odd ratio 1.11 95% CI: 1.05 - 1.17, p ≤ 0.001), high HbA1C % (Odd ratio 1.94 95% CI: 1.54 - 2.45, P ≤ 0.001), albumin creatinine ratio (Odd ratio 1.01, 95% CI: 1.00 - 1.01, P ≤ 0.001 ) and cholesterol level (Odd ratio 1.01 95% CI: 1.01 - 1.02, p = 0.001) were found as risk factors for early neuropathy and vasculopathy. Conclusion: Peripheral neuropathy and vasculopathy are frequently reported complications among newly diagnosed treatment naïve patients of type 2 DM. Age, duration of symptoms prior to diagnosis, metabolic parameters like raised HbA1C, hyperlipidemia and spot random albumin creatinine ratio are found to be risk factors for both peripheral neuropathy and vasculopathy.
文摘The aim of this research was to study the clinical features and microvascular complications risk factors of early-onset type 2 diabetes mellitus(T2DM).We analyzed the clinical data from 1421 T2DM inpatients at Wuhan Union Hospital.Subjects were divided into early-onset T2DM group(diagnostic age<40 years)and late-onset T2DM group(diagnostic age>40 years).All subjects underwent a standardized assessment of microvascular complications.Data were compared with independent-samples t test or Chi-square test.Multiple logistic regression was used to determine the risk factors of microvascular complications.Patients with early-onset T2DM were more inclined to have a lower systolic blood pressure(SBP),a longer duration of diabetes and higher levels of body mass index(BM1),uric acid(UA),fasting plasma glucose(FPG),total cholesterol(TC),triglyceride(TG)and glycosylated hemoglobin(HbAlc)than those with lateonset T2DM(P<0.05).The prevalence of diabetic retinopathy(DR)was significantly higher and that of diabetic peripheral neuropathy(DPN)was significantly lower in early-onset group than in late-onset group(P<0.05).For DN,UA was an independent risk factor in early-onset T2DM.SBP and TG were independent risk factors in late-onset T2DM.For DR,duration of diabetes and SBP were independent risk factors in early-onset T2DM.Duration of diabetes,SBP and HbAlc were independent risk factors in late-onset T2DM.This study demonstrated that the clinical characteristics of early-onset T2DM were metabolic disorders,including glucose metabolism,lipid metabolism and amino acid metabolism.Early-onset T2DM was more likely to be associated with DR.The potential pathogenesis of early and late-onset T2DM might be different.The management of metabolic risk factors especially HbA1c,SBP,TG and UA is advised to be performed in the early stage of diabetes.
文摘BACKGROUND： Prostaglandin El improves diabetic peripheral neuropathy in symptoms and sensory threshold. Vitamin Bi and methyl-vitamin BI2 improve microcirculation to peripheral nerve tissue and promote neurotrophy. OBJECTIVE： To observe motor nerve and sensory nerve conduction velocity in patients with diabetic peripheral neuropathy, prior to and after treatment with prostaglandin El, vitamin B I and different doses of vitamin B 12. DESIGN, TIME AND SETTING： Randomized, controlled experiment, performed at the Department of Neurology, Beijing Hantian Central Hospital, between February 2002 and September 2007. PARTICIPANTS： A total of 122 patients with type 2 diabetic peripheral neuropathy; 73 males and 49 females were included. All patients met the diagnostic criteria of diabetes mellitus, as determined by the World Health Organization in 1999 and 2006, and also the diagnostic criteria of diabetic peripheral neuropathy. For each subject, conduction disorders in the median nerve and in the common peroneal nerve were observed using electromyogram. Also, after diet and drug treatment, the blood glucose level of subjects was observed to be at a satisfactory level for more than two weeks, and the symptoms of diabetic peripheral neuropathy were not alleviated. METHODS： All patients were randomly divided into the following three groups. A control group （n = 40）, in which, 100 mg vitamin B1 and 500 μg vitamin BI2 were intramuscularly injected. A vitamin B12 low-dose treated group （ n = 42）, in which 10 μ g prostaglandin E1 in 250 mL physiological saline was intravenously injected once a day and 100 mg vitamin BI and 500 11 g vitamin BI2 was intramuscularly injected once a day. Lastly, a vitamin B12 high-dose treated group （n = 40）, in which administration was the same as in the vitamin B12 low-dose treated group, except that 500 11 g vitamin BI2 was replaced by 1mg vitamin B12. Administration was performed for four weeks for each group. MAIN OUTCOME MEASURES： The motor nerve and sensory nerve conduction velocity of the median nerve and the common peroneal nerve were determined using an electromyogram electronic stimulator （Neuropack-11, Nihon Kohden, Japan）. RESULTS： The motor nerve and sensory nerve conduction velocities of the median nerve and the common peroneal nerve were significantly faster after treatment compared to before treatment in all 3 groups （P 〈 0.05q）.01）. Compared with the control group, the motor nerve and sensory nerve conduction velocities were significantly faster in the vitamin B12 low-dose treated group and in the vitamin B12 high-dose treated group （P 〈 0.01）. The motor nerve and sensory nerve conduction velocities were significantly faster in the vitamin B12 high-dose treated group compared to the vitamin B12 low-dose treated group （P 〈 0.05）. CONCLUSION： Prostaglandin E1, in conjunction with vitamin B12, can improve neural functional states and speed up peripheral motor nerve and sensory nerve conduction velocity in diabetic peripheral neuropathy. In addition, better effects are achieved using prostaglandin E1 in conjunction with high doses of vitamin B 12.
文摘To examine the effects of Cerebrolysin on the treatment of diabetic peripheral neuropathy, we first established a mouse model of type 2 diabetes mellitus by administering a high-glucose, high-fat diet and a single intraperitoneal injection of streptozotocin. Mice defined as diabetic in this model were then treated with 1.80, 5.39 or 8.98 m L/kg of Cerebrolysin via intraperitoneal injections for 10 consecutive days. Our results demonstrated that the number, diameter and area of myelinated nerve fibers increased in the sciatic nerves of these mice after administration of Cerebrolysin. The results of several behavioral tests showed that Cerebrolysin dose-dependently increased the slope angle in the inclined plane test（indicating an improved ability to maintain body position）, prolonged tail-flick latency and foot-licking time（indicating enhanced sensitivity to thermal and chemical pain, respectively, and reduced pain thresholds）, and increased an index of sciatic nerve function in diabetic mice compared with those behavioral results in untreated diabetic mice. Taken together, the anatomical and functional results suggest that Cerebrolysin ameliorated peripheral neuropathy in a mouse model of type 2 diabetes mellitus.
文摘The effects of large dose methylcobalamin injection on diabetic peripheral neuropathy in patients were observed to observe the subjective symptom of diabetic perpheral neuropathy （DPN） patients and detect the motor nerve conduction velocity （MCV） and sense nerve conduction velocity （SCV）. Fifteen patients were received large dose methylcobalamin injection for two weeks as treatment group, another eleven patients were received muscular injection VitB1 100mg/ d, VitB12 500ug/ d for two weeks as control group. After 2 weeks treatment the subjective symptoms and signs were significantly improved with a total effective rate of 82.9% in the treatment group however the effective rate only has 52.0% in the control group. The result has obvious difference in statistics nerve MCV in median common peroneal nerve, SCV in median and superficial peroneal nerve were improved significantly in the treatment group and no such changes were observed in the control group. So, large dose methylcobalamin is an effective and safe agent for treatment of diabetic peripheral neuropathy.

文摘BACKGROUND Diabetic peripheral neuropathy(DPN)is a chronic and serious microvascular complication of diabetes linked to redox imbalance.Sestrin2,a novel inducible stress protein,participates in glucose metabolic regulation and redox homeostasis.However,the association between serum Sestrin2 and DPN is unknown.AIM To explore the association between serum Sestrin2 and DPN in patients with type 2 diabetes mellitus(T2DM).METHODS A total of 96 T2DM patients and 39 healthy volunteers,matched by age and sex,participated in this cross-sectional study.Clinical features and metabolic indices were identified.Serum Sestrin2 was measured by ELISA.The association between Sestrin2 and DPN was studied.Correlation and logistic regression analyses were used to evaluate the associations of different metabolic indices with Sestrin2 and DPN.RESULTS The 96 patients with T2DM were divided into DPN(n=47)and patients without DPN(n=49).Serum Sestrin2 was significantly lower in healthy volunteers than in all T2DM patients combined[9.10(5.41-13.53)ng/mL vs 12.75(7.44-23.80)ng/mL,P<0.01].T2DM patients without DPN also had significantly higher levels of Sestrin2 than healthy volunteers[14.58(7.93-26.62)ng/mL vs 9.10(5.41-13.53)ng/mL,P<0.01].However,T2DM patients with DPN had lower circulating Sestrin2 levels compared to T2DM patients without DPN[9.86(6.72-21.71)ng/mL vs 14.58(7.93-26.62)ng/mL,respectively,P<0.01].Bivariate correlation analysis revealed that serum Sestrin2 was positively correlated with body mass index(r=0.672,P=0.000),hemoglobin A1c(HbA1c)(r=0.292,P=0.000),serum creatinine(r=0.206,P=0.016),triglycerides(r=0.731,P=0.000),and fasting glucose(r=0.202,P=0.040),and negatively associated with estimated glomerular filtration rate(r=-0.230,P=0.007).After adjustment for sex,age,HbA1c,and diabetes duration,multiple regression analysis revealed that Sestrin2 was independently correlated with body mass index and triglyceride levels(P=0.000).Logistic regression analyses indicated that Sestrin2,diabetes duration,and high-density lipoprotein were strongly associated with DPN(odds ratio=0.855,1.411,and 0.041,respectively).CONCLUSION Our results show Sestrin2 is decreased in T2DM patients with DNP.As lower Sestrin2 is independently associated with DPN,Sestrin2 may contribute to progression of DPN in T2DM patients.

文摘Angiogenin is associated with the pathogenesis of diabetic peripheral neuropathy. Here, we se- quenced the coding region of the angiogenin gene in genomic DNA from 207 patients with type 2 diabetes mellitus （129 diabetic peripheral neuropathy patients and 78 diabetic non-neuropathy pa- tients） and 268 healthy controls. All subjects were from the Han population of northern China. No mutations were found. We then compared the genotype and allele frequencies of the angiogenin synonymous single nucleotide polymorphism rs11701 between the diabetic peripheral neuropathy patients and controls, and between the diabetic neuropathy and non-neuropathy patients, using a case-control design. We detected no statistically significant genetic associations. Angiogenin may not be associated with genetic susceptibility to diabetic peripheral neuropathy in the Han population of northern China.
文摘Background: Diabetic peripheral neuropathy (DPN) is a common complication among children with TIDM and is related to poor glycemic control. The aim of the study is to determine prevalence and determinants of diabetic neuropathy in diabetic children. Material& Methods: This is a cross sectional study conducted on 50 children having Type I diabetes mellitus for more than year presented to Pediatric Neurology and Endocrinology Outpatient Clinics, Sohag University Hospital, Sohag, Egypt, during one year duration (2017). Children were subjected to detailed neurological examination and electrophysiologic studies in addition to recording of socio demographic and laboratory findings with special regard to level of HbA1c. Results: The mean age of the studied children was 10.5 ± 0.3 years ranging from 5 to 18 years. 22 cases (44%) were younger than 10 years, 27 children (54%) were females. DPN was diagnosed in 12% of the studied children. No significant relation was found as regard age, gender, family history, consanguinity and duration of the diseases. Significant association was found between the HbA1c level and development of DPN in the studied children. Conclusion: Based on the results of this study, 12% of the studied diabetic children had DPN of whom more than 16% had subclinical neuropathy indicating the need for annual screening of neuropathy using Nerve Conduction Study. Moreover strict glycaemic control is needed to prevent rapid development of diabetic among these children.
文摘Background: Diabetes Mellitus is a wide-ranging metabolic disorder, which constitutes a most important physical condition dilemma in the world. Hypomagnesaemia accelerates the rate of diabetic complications. Objective: To analyze the association of serum magnesium (Mg) in Type 2 Diabetes Mellitus with and without complication of peripheral neuropathy. Design: A cross sectional study. Setting: This research was carried out in medicine department, Peoples Medical College Hospital Nawabshah from May 2016-April 2017. Sample Size: Total 271 patients of both genders with Type 2 DM with and without peripheral neuropathy, each group after fulfilling the selection criteria were included. Material and Methods: After a short-lived consultation, the subjects were categorized for variable analyses like sex, age, Type 2 Diabetes Mellitus with and without peripheral neuropathy, duration of diabetes mellitus and presence of hypomagnesaemia. Clinical examination with monofilament was applied for diagnosis of peripheral neuropathy. Blood samples for magnesium analysis were collected in fasting condition. Results: In 271 diagnosed patients of Type 2 diabetes mellitus, 180 male and 91 were females. Peripheral neuropathy was observed in 136 subjects out of them 94 males and 42 were females. While 135 were without peripheral neuropathy out of them 86 males and 49 were females. Normal magnesium was seen in 119 (43.91%) and low magnesium was present in 152 (56.09%) patients overall. A decreased serum level of magnesium was observed in 56.09% diabetic subjects with peripheral neuropathy and 50% subjects with diabetes without peripheral neuropathy. Conclusion: Frequency of hypomagnesaemia is common in subjects with in Type 2 DM with and without peripheral neuropathy.
文摘At present, unified and effective treatment for diabetic peripheral neuropathy （DPN） is still lacking, however Chinese medicine techniques characterized by syndrome differentiation and treatment, for example traditional Chinese medicine preparations, acupuncture, and fumigation, have been considered the promising alternative for DPN. Traditional Chinese medicine nursing, which is development on the basis of traditional Chinese medicine （TCM） theory, uses not only acupuncture, acupoint application and other treatments but also cares for the patient＇s diet and emotions in order to promote the recovery of skin and nerve endings in patients with DPN. Vast amounts of studies have explored the efficacies of various TCM nursing techniques in managing DPN, however, the article, which comprehensively documented these TCM nursing techniques in DNP patients, cannot be cap- tured. In the present article, we summarized the latest findings of TCM research on DPN in recent years in order to provide a reference for DPN.
