OBJECTIVETo summarize and analyze the compatibility laws for acupoint selection of acupuncture in treating diabetic gastroparasis (DGP) in modern literatures of clinical researches.
METHODSRetrieved were literatures related to treating DGP by acupuncture or acupuncture combined other therapies from PubMed, CNKI, and WF from 1982 to 2014. Analyzed were frequency of acupoint use, meridians selected acupoints belonged to, regions selected, association laws of selected compatible acupoints.
RESULTSRetrieved were 35 with compatibility frequencies more than 15 listed as follows: compatibility frequency of Zusanli (ST36) and Zhongwan (CV12) was 33 (94.29%); compatibility frequency of Zusanli (ST36) and Neiguan (PC6) was 23 (65.71%), compatibility frequency of Zhongwan (CV12) and Neiguan (PC6) was 22 (62.86%), compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Neiguan (PC6) was 22 (62.86%); compatibility frequency of Zusanli (ST36) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zhongwan (CV12) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Sanyinjiao (SP6) was 15 (42.86%). Meridians selected acupoints belonged to were sequenced as Foot Yangming Stomach channel, Ren channel, Foot Taiyang Bladder channel, and so on. Acupoints selected were mainly in lower limbs, chest and abdomen, waist and back. The compatibility of Zusanli (ST36) and Zhongwan (CV12) was the most often used with the highest frequency.
CONCLUSIONSThe compatibility laws for acupoint selection of acupuncture in treating DGP were mainly dominated as upper-lower selection, three regions selection, local selection, anterior-posterior selection. The compatibility laws for acupoint selection of acupuncture along meridians were mainly dominated as the convergence points and exterior-interior meridian points.

Objective To investigate the correlation between enlarged perivascular space (EPVS) and post-stroke depression (PSD) in patients with ischemic stroke. Methods Consecutive patients with acute cerebral infarction admitted to hospital from March 2010 to March 2014 were enroled prospectively. The patients completed head MRI examination after admission and performed EPVS grading. At 3 months after symptom onset, they performed PSD assessment according to Hamilton Depression Scale (HAMD) and Classification and Diagnostic Criteria of Mental Disorders in China, 3rd edition (CCMD-3). The relationship between EPVS and PSD was analyzed. Results A total of 249 patients were enroled; including 62 patients (4. 9% ) experienced PSD at 3 months. There were significant differences in the proportions of the EPVS classification patients of the baseline National Institutes of Health Stroke Scale score ( the median [interquartile range]; 4 [3 - 6] vs. 3 [2 - 5]; Z = - 2. 950, P = 0. 003), centrum semiovale (χ2 = 14. 370, P = 0. 001), and periventricular (χ2 = 11. 590, P = 0. 003)between the PSD group and the non-PSD group. Multivariable logistic regression analysis showed that centrum semiovale EPVS grade 2 (odds ratio [OR] 3. 89, 95% confidence interval [ CI] 1. 59 - 9. 56) and grade 3 (OR 3. 28, 95% CI 1. 04 - 10. 33) were significantly correlated with PSD; periventricular EPVS grade 2 (OR 0. 72, 95% CI 0. 27 - 1. 91) and grade 3 (OR 2. 24, 95% CI 0. 68 - 7. 37) were not correlated with PSD. Conclusions Centrum semiovale EPVS is independently associated with PSD, and periventricular EPVS is not.

Objective To evaluate dynamic contrast-enhanced MRI (DCE-MRI) with Patlak model for depicting the perfusion and permeability characteristics of lesions and normal-appearing white matter (NAWM) regions in patients with relapsing-remitting multiple sclerosis (RRMS). Methods Twenty-three patients with clinical confirmed RRMS were retrospectively analyzed, who had underwent conventional MRI and DCE-MRI using a 3.0 T MR scanner . The clinical characteristics and imaging data were collected. Post-processing was performed using the Patlak model. Volume transfer constant (Ktrans), fractional plasma volume (Vp) and perfusion parameters including cerebral blood flow (CBF) and cerebral blood volume (CBV) were represented as median and interquartile range(IQR). The four parameters of non-enhanced(NE) lesions, NAWM regions located close to NE lesions(NAWM close) and NAWM regions located far from NE lesions (NAWM far) were compared using the Kruskal-Wallis H rank sum test. Artificial color mappings were also proceeded. Results MR imaging biomarkers Ktrans was 0.132(0.064, 0.233) min-1 for NE lesions, 0.111 (0.060, 0.233) min-1 for NAWM close and 0.077(0.044, 0.185) min-1 for NAWM far, respectively. CBV was 10.660(5.555, 22.193) ml · 100 g-1 for NE lesions, 9.359(4.883, 16.290) ml · 100 g-1 for NAWM close, 6.814 (4.699, 13.623) ml·100 g-1 for NAWM far, respectively. Ktrans and CBV of NE lesions was significantly higher than that of NAWM far(χ2=7.582,P<0.05;χ2=6.394,P<0.05, respectively). Ktrans and CBV of NAWM close showed no significant differences compared with NE lesions and NAWM far. Vp and CBF had no significant differences between NE lesions, NAWM close and NAWM far regions(P>0.05). Conclusion DCE-MRI with Patlak model can measure perfusion and permeability characteristics and hemodynamic abnormalities of NE lesions and NAWM regions in patients with multiple sclerosis.
