AIM: To investigate the plasma neurotensin(NT) concentration in patients with coronary heart disease: acute myocardial infarction(AMI),unstable angina(UA),stable angina pectoris(SAP), old myocardial infarction (OMI), and to study the relationship between the plasma NT level and the myocardial ischemia . METHODS: The plasma NT concentration of 30 patients with AMI,32 patients with UA,35 patients with SAP, 31 patients with OMI and 32 normal controls were determined by radioimmunoassay(RIA). RESULTS: The plasma NT level in patients with AMI(24 h),in patients with UA when angina attacked is significantly higher than that of healthy controls. The plasma NT level in patients with SAP, in patients with OMI is not significantly different from that of healthy controls. The NT level of patients with UA when angina attacked is significantly higher than that after 2 weeks treatment (P

Objective: To analyze the clinical symptoms and hereditary information of suspicious juvenile neuronal ceroid-lipofuscinosis (JNCL) and determine the genotype in order to explore the diagnosis clues in the patients with ophthalmologic manifestations being initial symptom. Methods: A case-control study was performed in this study.Two families were included in Eye Hospital of Wenzhou Medical in 2013 and 2017, respectively.Medical histories were collected and all participants underwent comprehensive ophthalmologic examinations, and the best corrected visual acuity (BCVA) was obtained.Fundus photography and optical coherence tomography (OCT) were used to image the retinal signs, and visual electrophysiology was recorded to evaluate the visual function.Genomic DNA of 3 patients who initially visited to ophthalmologists and 5 unaffected family members were extracted.Whole exome sequencing (WES), targeted exome sequencing (TES), Sanger sequencing and comprehensive analyses of pathogenicity were performed to determine the genetic cause of the patients.This study was approved by Ethics Committee of Eye Hospital of Wenzhou Medical University (KYK-2017-7), and written informed consent was obtained from each subject prior to any medical examination. Results: All patients presented bull eye sign and disorder of pigment on the fundus photograph, and the retinas were thinning on the OCT image, indicating the diffuse retinal pigment epithelium atrophy of macula and loss of outer layer structure of retina.Three mutations in CLN3 gene were identified by WES, TES, Sanger validation and assessments of pathogenicity, including c. 154T>C(p.Y52H), c.982G>C(p.A328P) and c. 906+ 5G>A, among which p. A328P was a novel mutation.Patients of F1 family harbored the compound heterozygous mutations c. 154T>C (p.Y52H) and c. 982G>C(p.A328P), while proband of F2 family harbored the homozygous splice site mutation c. 906+ 5G>A, which was reported to be a pathogenic mutation of JNCL.Co-segregation and comprehensive pathogenicity analysis revealed that the compound heterozygous mutations in F1 family and the homozygous mutation in a splice site in F2 family were the genetic causes of their phenotypes. Conclusions A novel mutation in CLN3 gene for JNCL is identified, which expands the mutation spectrum of CLN3 gene.Considering the high clinical heterogeneity of inherited retinal diseases, especially syndromic cases, genetic test through next generation plays a vital role in diagnosis, guiding future treatment and prognostic evaluation.

Standardization is the universal language of the world, and standardization of traditional Chinese medicine (TCM) is essential for its communication in China and globally. However, the principles and methods of TCM acupuncture standardization have been unclear and inadequate in the early stages. Based on an investigative approach to understanding the current status, identifying problems, and finding solutions, our team has established basic principles of TCM acupuncture that embody Chinese wisdom, evaluated the international strategic environment systematically, proposed the principle of “importance of harmony and exercise of impartiality”, and established basic working principles. A series of methods for TCM acupuncture standard development and evaluation have been constructed, including general standards for the revision of TCM acupuncture standards, the first TCM acupuncture clinical research management specification, a shared full chain technology platform, a data center, and an evaluation research base for TCM acupuncture clinical research. Evaluation criteria for ancient literature and expert experience, a recommendation method for the “three main and three auxiliaries” TCM guideline for prevention were established, and quantifiable assessment methods of TCM standard applicability were proposed. These findings provide methodological guidance for TCM acupuncture standardization.
