ABSTRACT

Objective:To observe any effect of repeated transcranial magnetic stimulation (rTMS) in the treatment of diabetic peripheral neuropathic pain (DPNP).Methods:Eighty-six persons with type 2 diabetes mellitus and DPNP were randomly divided into an observation group and a control group, each of 43. Both groups were given basic treatment to control plasma glucose and blood pressure, while the observation group was additionally provided with daily 10Hz rTMS of the primary motor cortex (M1 area) of the non-dominant hand 5 days a week for 4 weeks. Before and after the treatment, pain in both groups was evaluated using a visual analog scale (VAS) and the Patient′s Global Impression Change scale (PGIC). The motor conduction velocity (MCV) and sensory conduction velocity of the median and the common peroneal nerves were also tested.Results:After treatment, the average VAS pain rating and PGIC score of the observation group were significantly lower than the control group′s averages and those before treatment. The observation group′s treatment effectiveness rate (79.07%) was then much better than that of the control group (23.26%). After the treatment, the average MCV of the median and common peroneal nerves of the observation group (47.65±1.94 m/s and 46.98±3.26 m/s, respectively) were significantly faster than before treatment, and those of the control group.Conclusions:rTMS based on routine intervention can significantly relieve DPNP and promote the recovery of injured nerves, bettering diabetics′ physical condition and life quality.

ABSTRACT

Objective:To investigate the predictive value of peripheral blood platelet to lymphocyte ratio(PLR)for the survival of elderly type 2 diabetes mellitus(T2DM)patients with diabetic ketoacidosis(DKA).Methods:Clinical data of 137 elderly T2DM patients with DKA admitted to our hospital between January 2014 and December 2018 were divided into the survival group(n=109)and the death group(n=28)and retrospectively analyzed.Another 137 elderly T2DM inpatients without DKA during the same period were enrolled as the control group.Clinical data of all patients were recorded to analyze predisposing factors of DKA.Multivariate Logistic regression analysis was used to analyze the related factors for the death in elderly T2DM patients with DKA.The best cut-off value for PLR to predict the survival status of patients was determined.Results:The main predisposing factors for DKA were pulmonary infections and insufficient insulin. Logistic multivariate analysis showed that diastolic blood pressure, Glasgow coma score, the coexisted other organ failure, PLR( OR: 3.576, 95% CI2.225~5.472)and mechanical ventilation were risk factors for the survival in elderly T2DM patients with DKA( P<0.05). ROC curve analysis indicated that the area under the curve(AUC)of PLR was 0.803( P=0.002, 95% CI: 0.758-0.886). The optimal cut-off value of PLR for prognosis(survival/death)was 224.29, with a sensitivity of 81.7% and a specificity of 70.1%. Conclusions:PLR is easy to obtain and can be used as a sensitive indicator to predict the survival of elderly T2DM patients with DKA.

ABSTRACT

Objective To investigate the effect of blood glucose level on pulmonary diffusion capacity in elderly patients with type 2 diabetes and its clinical significance.Methods Totally 132 older adults with type 2 diabetes were enrolled in this study.According to blood glucose level,the patients were divided into well-controlled group (n =57) and poor controlled group (n =75).Additionally,52 age-matched non-diabetic healthy subjects were selected as control group.Levels of fasting blood glucose (FBG),glycosylated hemoglobin (HbA1c),fasting insulin (FINS) and 2-hour postprandial glucose (2h PG) in the diabetic patients were detected,and homeostasis model assessment of insulin resistance (HOMA IR) was calculated.The patients with type 2 diabetes underwent urinary albumin excretion rate (UAER) detection,fundus examination and nerve conduction velocity test.pulmonary ventilation,diffusion of the lungs for carbon monoxide (DLCO) and DLCO corrected by alveolar volume (DLCO/VA) were examined in all subjects.Results Levels of FBG,2h PG,HbA1c and HOMA-IR were higher in poor-controlled group than in good glycemicwell-controlled group (all P<0.05).Compared with the control group,body mass index (BMI) was increased in diabetic groups (both P<0.05).The pulmonary ventilation function in the three groups had no significant differences (P>0.05).DLCO and DLCO/VA were lower in diabetic groups than in the control group(all P<0.05).DLCO and DLCO/VA in poor-controlled group were lower than those in well controlled group (both P<0.05).DLCO and DLCO/VA were lower in patients with microangiopathy score ≥ 2 than those without microangiopathy (both P < 0.05).Multiple liner regression analysis showed that DCLO and DLCO/VA were negatively correlated with HbA1c,HOMA-IR,duration of diabetes and microangiopathy (r=-2.51,-2.35,-2.42,-2.37,-2.41,-2.52,-2.47,-2.36,all P<0.05).Conclusions The pulmonary diffusion capacity is significantly impaired in elderly patients with type 2 diabetes.Pulmonary diffusion capacity is negatively correlated with the blood glucose level.The lung may be one of the target organs of type 2 diabetes mellitus.

ABSTRACT

Objective:To improve the sensitivity and the linear range of electrochemical immunosensor to detect Schistosoma japonicum (S.japonicum) antibody.Methods:Carbon inks and silver/silver chloride inks were printed on a polyethylene terephthalate (PET) board to make a two-electrode test strip,where carbon was the working electrode and S.japonicum soluble egg antigen (SEA) was fixed at one end of working electrode by different methods; silver/silver chloride electrode was used as control.We tested the valency of the antibody by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) in an electrochemistry workstation,and conducted comparison with the results of ELISA.Two new immunosensing electrodes have been developed,based on glutaraldehyde cross-linked (GA) or chitosan-glutaraldehyde cross-linked (Chit-GA) transducer fixing S.japonicum antigen.We tested the titer of the antibody by means of CV and DPV.Results:Our experimental S.japonicum antigen (50 μg/L) is the optimal test concentration for the GA sensor,and 10 μg/L for Chit-GA sensors.The immune reaction time of both electrodes is all essentially complete in 1 minute.The linear range for S.japonicura antibody in human positive serum sample detection by the glutaraldehyde cross-linked immunosensor is 1∶1000 to 1∶400,and by the chitosan-glutaraldehyde cross-linked immunosensor is 1∶1000 to 1∶500.As the concentration of dilution ratio of S.japonicum antibody in human positive serum sample increased,the test value of DPV increased proportionally.Conclusion:GA sensor and Chit-GA cross-linked S.japonicum sensors have high sensitivity and broad linear range response,and both exhibited a good linear relationship between the DPV signal and the test antibody titer.

ABSTRACT

Objective To investigate the inhibition rate of cell proliferation, cell apoptosis rate and their effects on the cell cycle proceeding of the SSMC7721 cell line when 5-FU combined with thermotherapy is induced into the cells, and then provide theoretical bases to the combined therapy of hepatocellular carcinoma. Methods The inhibition rate of cell proliferation was detected by the MTT under different conditions, the cell cycle proceeding and the cell apoptosis rate was detected by flow cytometry and the subcellular structure was detected by the electronmicroscope. Results The cell inhibition rate of the thermotherapy group, 5-FU group and the combinedgroup were 18.4% ,28. 3% and 52. 7% ,respectively. The inhibition rates in the latter two groups were significantly different to the thermotherapy group. The results of flow cytometry showed that the cell numbers increased in G1 stage decreased in S stage,and increased in G2/M stage;the cell apoptosis rate increased. There was significant difference between different groups(P < 0.01 or P <0.05). The results of the electronmicroscop showed that the nuclear chromatins agglutinated in the borderline and the mitochondriums became swelled. Conclusions The 5-FU combined with thermotherapy could significantly improve the inhibition rate of cell proliferation, inhibit the cell cycle proceeding from G1 stage to S stage, and induce cells apoptosis and change the subcellular structures in the SSMC7721 cell line.
