Objective To investigate the clinical effect of low frequency electrical pulse therapy combined with α-lipoic acid on diabetic gastroparesis in elderly patients with type 2 diabetes.Methods A total of 65 patients diagnosed as diabetic gastroparesis were selected from our hospital and divided into three groups according to random number table:the control group(n =23,the α-lipoic acid treatment),the conventional treatment group (n =16),and the experimental group (n =26,treating with α-lipoic acid combined with low-frequency electrical pulse therapy).All patients received the conventional diabetic therapy.Clinical effects,gastric emptying rate and serum gastrin(GAS) and fasting blood glucose levels were compared before versus after treatment among the three groups.Results The cure and total effective rates were higher in the experimental group than in the control group [46.15％ (12 cases) vs.30.43％ (7 cases),80.76％ (20 cases) vs.65.21％ (15 cases),x2 =0.867,P＜0.05].There were significant differences in gastric emptying rate,serum gastrin and fasting plasma glucose levels among the 3 treatment groups before versus after treatment.And the gastric emptying rate and serum gastrin level were better improved in the experimental groups compared with the conventional treatment and control groups.Conclusions The low-frequency electrical pulse therapy combined with α-lipoic acid has a significant clinical efficacy,which can improve clinical effects,promote gastric emptying,decrease fasting plasma glucose levels in elderly patients with type 2 diabetes.

The antioxidative capability and Na+-K+-ATPase α1-subunit mRNA expression in myocardium of hypothyroid rats induced by low-iodine diet were observed. The results showed that the antioxidative capability of myocardium decreased, resulting in lipid peroxidative damage, atrophy of myocardial cells and chondrification of tunica intima, along with decreased expression of sodium pump α1 subunit mRNA in hypothyroid rats.

Objective To perform mutation analysis of survival motor neuron gene 1 (SMN1 in two spinal muscular atrophy (SMA) patients and their parents to evaluate the effects of the two SMN1 gene mutations on the transcript levels of the gene and preliminarily predict their effects on the structure and function of SMN protein.Methods Mutation analysis of SMN1 gene was carried out by multiplex ligationdependent probe amplification,reverse transcript-polymerase chain reaction (RT-PCR) and cloning sequencing.Transmission of the mutations was confirmed by the mutation analysis in patients' parents.The full-length SMN1 (SMN1-fl) transcript levels of the patients carrying these subtle mutations were detected using quantitative RT-PCR.Results The two patients were diagnosed as SMA Ⅱ and SMA Ⅲ.They carried p.Val19GlyfsX21 and p.Ala2Gly SMN1 mutations in SMN1 gene,respectively.Both of the two mutations were originated from their fathers.Compared with the healthy individuals (23.5 ± 4.9),the two patients had a significant reduction in the level of SMN1-fl transcripts (t =3.322,P =0.011 (p.Ala2Gly) ;t =6.964,P =0.000 (p.Val19GlyfsX21)).However,compared with the healthy carriers (14.1 ±4.5),the patient with p.Ala2Gly mutation had no significant reduction in the level of SMN1-fl transcripts (13.9 ±3.6,t =0.058,P =0.955) ; however,the patient with p.Val19GlyfsX21 mutation had a significant reduction (4.9± 2.4,t =3.725,P =0.004).Conclusions Two SMN1 gene mutations are identified in our study.The mutation p.Val19GlyfsX21 is a novel mutation and p.Ala2Gly is firstly reported in Chinese SMA patients.p.Val19GlyfsX21 may possibly lead to decreased SMN1-fl mRNA by nonsense-mediated messenger RNA decay,however,p.Ala2Gly has no obvious effects on the amount of the SMN1-fl transcripts,indicating that its deleterious effect may be occurring at SMN protein level or the function of SMN protein.
