ABSTRACT
Objective:To analyze the rules and distribution of acupuncture points used in pediatric tuina treatment for autumn diarrhea, and to provide a theoretical basis for the promotion and application of Tuina treatment techniques for pediatric diarrhea.Methods:We searched the literature on Tuina treatment of pediatric autumn diarrhea in the Chinese academic journals full-text database (CNKI), Chinese science and technology journals full-text database (VIP), Wanfang database and Chinese biomedical database (SinoMed), and collected the Tuina prescriptions on children's autumn diarrhea disease from the database to March 2021,with the help of the Traditional Chinese Medicine Inheritance Support Platform (V 2.0) software,and Data mining technology was applied to analyze the common acupoints and acupoint distribution of pediatric Tuina treatment of autumn diarrhea to form the core acupoints used in pediatric Tuina treatment of autumn diarrhea.Results:A total of 101 pediatric autumn diarrhea Tuina prescriptions were screened, involving 61 acupoints, among them 18 acupoints used more frequently, and 35 acupoint combinations were obtained, including 15 two-acupoint combinations, 11 three-acupoint combinations, and 2 four-acupoint combinations, and 7 new acupoint combinations were obtained.Conclusion:The core points mainly belong to the spleen meridian, large intestine meridian, abdomen, seven knotted bones, turtle tail, spine, and umbilicus, which can be used as a basic Tuina prescription for clinical reference.
ABSTRACT
Poly (lactic acid) (PLA) is a polymer synthesized from lactic acid with good biocompatibility and biodegradability. At present, PLA manufactured on industrial scale is mainly synthesized from L-lactic acid. The obtained products have good transparency but poor heat resistance. Adding nucleating agents could increase the crystallinity of PLA, to improve heat resistance. We reviewed the progress of research on organic and inorganic nucleating agents that can be used for PLA synthesis.

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.
