Objective To systematically review the effectiveness and safety of transcutaneous electricalnerve stimulation (TENS) on symptomatic diabetic neuropathy (DNP). Methods Electronic databases such asPUBMED, EMBASE, Cochrane Central Register of Controlled Trials, and Chinese Biomedical Database weresearched by using such mesh and text keywords as "TENS" and "diabetic neuropathy". Randomized controlled trials(RCTs) on the effect of TENS on symptomatic diabetic neuropathy were included. Studies were selected and availa-ble data was extracted independently by two reviewers. Meta-analysis was performed using RevMan 4.2.8 software.Results Three RCTs involving 78 patients were included in this study. Compared with sham-stimulation, TENStherapy significantly reduced the score in pain (SMD -2.35, 95% CI [-4.24, -0.46 ] ) and the score in numb-ness (WMD -0.18, 95% CI [-0.32, -0.05 ] ). Subgroup analysis shows that TENS therapy was associated with a significant reduction in the score of pain in both 4-week treatment duration ( SMD - 5.37, 95% CI [ - 6.97,- 3.77 ] ) and 6-week treatment duration ( SMD - 1.01, 95% CI [ - 2.01, - 0.01 ] ), but not 12-week treatmentduration (SMD - 1.65, 95% CI [ -4.02, 0.73 ] ). Conclusion TENS therapy is a promising and safe strategyfor treatment of symptomatic diabetic neuropathy. More studies are still warranted to accumulate the evidence of theeffect of TENS therapy on DNP.

Objective To evaluate the diagnostic performance of the histogram analysis of mono-exponential and intravoxel incoherent motion(IVIM) models to the dualistic model of epithelial ovarian cancer(EOC). Methods Forty female patients with histopathologically proven epithelial ovarian cancer underwent preoperative MR examination. Scanning sequences included conventional imaging, diffusion-weighted magnetic resonance imaging with 11 b values (0, 30, 50, 100, 150, 200, 400, 600, 800, 1 000, 1 500 s/mm2) and dynamic contrast enhanced MRI (DCE-MRI). Based on the dualistic model of EOC, all patients were divided into two groups:typeⅠ(low grade, n=16) and typeⅡ(high grade, n=24). ADC, D, D*and f maps and their corresponding histograms were generated by post-processing software. Based on an entire-tumour measurement, the following histogram parameters were recorded, respectively: (a) Mean; (b) the 10th percentile (10th);(c) the mean of the top 10 percent (MeanL);(d) the 90th percentile (90th);(e) the mean of the bottom 10 percent (MeanR). Two types were compared using independent sample t test or Mann-Whitney U test. And areas under ROC curve between two groups were assessed. Results For ADC , D, and f, all indices(Mean,10th,MeanL,90th,MeanR) of the histogram were significantly lower in typeⅡthan in type Ⅰ(P<0.05). All of parameters of D* had no significant different(P>0.05). D demonstrated a comparable accuracy with ADC in differentiating the grade of EOC (area under curve: Mean, 0.898 vs. 0.893; 10th, 0.880 vs. 0.846; MeanL, 0.878 vs. 0.858; 90th, 0.895 vs. 0.839; MeanR, 0.872 vs. 0.814), and both ADC and D have better performance than f. Conclusion It is feasible to stratify the grade of EOC by mono-exponential and IVIM models with histogram metrics,diagnositic efficiency of ADC and D values are higher.

Chinese Journal of Postgraduates of Medicine 2020;43(6):556-559
Objective:To evaluate the clinical efficacy of sepsis in children by dynamic monitoring of serum procalcitonin (PCT) and hypersensitive C-reactive protein (hs-CRP).Methods:Seventy-five children with sepsis hospitalized in Taihe County People′s Hospital from January 2015 to April 2019 were selected as the sepsis group, and 75 healthy children in the same period were selected as the control group. The values of PCT and hs-CRP in two groups were detected by chemiluminescence and immunoturbidimetry respectively, and the levels of serum PCT and hs-CRP were compared between the two groups. According to the PCT, hs-CRP value and APACHE Ⅱ score at 72 h after treatment, children in sepsis group can be divided into two groups: good curative effect group (APACHE Ⅱ <27 scores)and poor curative effect group with (APACHE Ⅱ ≥27 scores).The changes of serum PCT, hs-CRP and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score in two group were monitored dynamically at different time points, and data were analyzed by SPSS 18.0 software.Results:The levels of PCT and hs-CRP in sepsis group were significantly higher than those in control group [(5.37 ± 1.56) μg/L vs. (0.32 ± 0.10) μg/L, (64.6 ± 9.5) mg/L vs. (4.2 ± 1.2) mg/L] ( P<0.01). At 1, 3 and 5 d after treatment, the levels of PCT, hs-CRP value and APACHE Ⅱ scores in good curative effect group were significantly reduced. However, the levels of PCT, hs-CRP and APACHE Ⅱ scores in poor curative effect group did not decrease significantly or even continued to increase, and the levels of PCT, hs-CRP and APACHE Ⅱ scores in good curative effect group at different time point were significantly higher than those in poor curative effect group ( P<0.01). In sepsis group, the level of PCT had positive correlation with hs-CRP and APACHE Ⅱ ( r=0.846, P<0.05; r=0.531, P<0.05), and the level of hs-CRP had positive correlation with APACHEⅡ( r=0.558, P<0.05). The sensitivity and specificity of PCT combined with hs-CRP in diagnosis of sepsis was 98.7% and 93.5%. Conclusions:PCT combined with hs-CRP detection is helpful for the early diagnosis of sepsis, and through the dynamic monitoring of PCT and hs-CRP values, the therapeutic efficacy of children can be evaluated.

OBJECTIVETo study effects of three pentacyclic triterpenoids, oleanolic acid (OA), ursolic acid (UA) and asiatic acid (AA) on Ca(2+)-induced liver mitochondrial permeability transition (MPT).
METHODEffects of three compounds on liver MPT induced by Ca2+ were assessed by measuring the change in mitochondrial swelling, mitochondrial membrane potential and release of matrix Ca2+ in vitro.
RESULTObvious mitochondrial swelling, loss of mitochondrial membrane potential and release of matrix Ca2+ occurred after the addition of 50 micromol x L(-1) Ca2+. However, preincubation with 50 mg x L(-1) OA, UA or AA significantly blocked the above changes. In addition, it was also found that there are differences in the inhibitions of three compounds on liver MPT induced by Ca2+.
CONCLUSIONThree pentacyclic triterpenoids, OA, UA and AA, have significant mitochondrial protection through blocking on liver MPT and the inhibition on liver MPT of AA is stronger than that of UA and OA.
