Objective: To understand the current situation of suicidal ideation in college students of Tianjin, and to provide reference for suicide prevention, early warning and emergency intervention. Methods: A total of 31 596 freshmen from one university in Tianjin were selected to participate in the mental health survey during 2013 to 2020. Results: A total of 1 349 freshmen reported suicidal ideation. The incidence of suicidal ideation varied from 2.60% to 6.18% across the years (the overall average annual incidence of suicidal ideation was 4.27%). Significant differences were observed in the incidence of suicidal ideation among freshmen of different origin (4.11% in urban areas, 4.74% in rural areas; χ 2=6.01, P <0.01), whether the only children in the family (4.10% in only children, 4.60% in non only children; χ 2=4.38, P <0.01). During the past five years, the in depth interview showed that the proportion of those with suicidal attempt ranged from 17.09%-33.73% (the total annual average proportion of those with suicidal attempt was 24.84%). Results from electroencephalonquadrantography varied significantly between college students with and without suicidal ideation and those with and without suicidal attempt. Conclusion It is necessary to strengthen the screening of college students for suicidal ideation and to identify the risk of students with suicide attempt, so as to provide a better reference for the prevention and intervention of psychological crisis.

To explore the application of gene chip technology in the acupuncture research so as to provide evidences for the mechanism of acupuncture for regulating bodies. The literature on the application of gene chip technology in the acupuncture field from 2001 to 2016 was collected in PubMed, Springer, CNKI and WANFANG databases, which was analyzed and summarized. There were some achievements of the technology for acupuncture research, focusing on the five aspects, including the study of the relationship between meridian-point and viscera, the influencing factors of acupuncture effect, the effect and mechanism of acupuncture analgesia, the mechanism of acupuncture anti-aging, the effect and mechanism of acupuncture for diseases of each system. Gene chip technology plays an important role in researching acupuncture mechanism. It is an important technology for genomics study of acupuncture. However, there are also some disadvantages such as high cost, deficient data mining, non-uniform observation objects, deficient professionals, etc. All those need further resolution so as to promote the application of this technology in the acupuncture researching field.

There are various contents about diagnosis and treatment of low back pain in(), which are closely related to meridians and collaterals, forming a complete theoretical system of meridian differentiation for low back pain. Its theory and application are interpreted in this paper from five main aspects, including 18 meridians and collaterals densely distributing in the tendons and bones of the waist, the pathogenesis of low back pain lying in the disorders of the meridianand blood, the nature of low back pain being reflected by the color and shape of meridians and collaterals, the disordered meridians of low back pain being first identified based on syndrome differentiation, the acupuncture prescription being selected according to meridian differentiation. The purpose of this paper is to guide clinical practice, explore the advantages and characteristics of meridian differentiation, and provide theoretical reference and evidence for promoting the standardization of TCM.
