Objective To examine the impact on impulsivity trait by monoamine oxidase A variable nucleotide tan?dem repeat (MAOA-VNTR) genotype and children’s abuse experience. Methods The self-reported questionnaire of Bar?ratt Impulsiveness Scale (BIS), Childhood Trauma Questionnaire (CTQ) were conducted in 403 normal Han female adoles?cents from north-west of China. The DNA were extracted from their venous blood sample and were genotyped for the MAOA-VNTR polymorphism. A linear regression model was used to investigate the main effects of MAOA-VNTR and children's abuse, and their interaction effect on impulsivity. Results The main effect of Children’s maltreatment experi?ence on trait impulsivity was significant (P<0.01). The main effect of MAOA-VNTR gene and the interaction between MAOA-VNTR genotype and children's maltreatment experience were insignificant (P>0.05). Conclusion The MAOA-VNTR genotype may not be involved in the female adolescents’impulsivity traits related to childhood maltreat?ment.

Objective To measure and analyze the behavioral changes of Rncat congenital cataract mice. Methods Normal BALB/c mice and KM mice were used as control group,and inbred and random mated Rncat congenital cataract mice were used as experimental group. Behavioral tests, including the open field test, coat-hanger test, forced swimming test,and tail suspension test,were conducted on the mice. Results Compared with the inbred Rncat congenital cataract mice,the residence time in the open field test,the immobility time in the forced swimming test and tail suspension test of the BALB/c mice, randomly-mated Rncat congenital cataract mice and KM mice were significantly different. Conclusions There are certain differences in behavioral performance between the Rncat congenital cataract mice and the other mice. Our findings may provide a useful reference for future researchers.

Periodontal pathogens are the main pathogenic factor of periodontitis. Periodontal pathogens have a large variety of virulence factors such as lipopolysaccharide, fimbriae and proteases, which enables the pathogens to infect periodontal tissues and stimulate the secretion of inflammatory cytokines, causing chronic systemic inflammation. Periodontal pathogens may invade multiple systems such as the circulatory system, immune system, respiratory system and digestive system to cause systematic diseases. Recent studies have shown that periodontal pathogens may have close relations with systemic diseases such as cardiovascular disease, diabetes, rheumatoid arthritis, and cancer. Among the periodontal pathogens, can be found in atherosclerotic plaques to impairing the function of the vascular endothelium; may also increase the level of inflammatory factors such as TNF-α to promote insulin resistance and diabetes. Many of the periodontal pathogens such as , and can be detected in the synovial fluid of rheumatoid arthritis patients, suggesting their involvement in the pathogenesis of rheumatoid arthritis. may cause alterations in the intestinal microbiome in mice and promote the occurrence of intestinal tumors. Herein we review the recent progresses in the relationship between periodontal pathogens and systemic diseases.

Objective To analyze and estimate, the treatment of patients with histologically confirmed subependymal giant-cell astroeytoma (SEGCA). Methods The data from 23 patients with SEG-CA who were diagnosed between February 1995 and February 2008 were retrospectively evaluated. Various combinations of surgery and radiotherapy had been used for treatment. Results Total resection was 16 cases, subtotal resection was 7 cases, radiotherapy was 17 cases. The average follow-up time was 53 months.One postoperative SEGCA recurrence. Epilepsy was totally disappeared in 17.6% (3/17), partly disappeared in 47.1%(8/17). All cases survived. Conclusions The key of treatment is total resection. The significance of radiotherapy is not sure. The overall prognosis of SEGCA is favorable.

Objective:To explore the effect of dyslipidemia on the clinical outcome of intracytoplasmic sperm injection-embryo transfer (ICSI-ET) in infertility patients receiving donor eggs.Methods:A total of 118 patients were selected to receive egg donors and ICSI-ET at the First Affiliated Hospital of Nanjing Medical University between April 2007 and December 2020. According to the levels of triacylglycerol, serum cholesterol, high density lipoprotein (HDL), and low density lipoprotein, they were divided into dyslipidemia group (35 cases) and normal blood lipids group (83 cases). The influence of body mass index (BMI) and age was adjusted by 1∶1 propensity score matching, and the general condition and clinical outcome of the two groups were analyzed retrospectively. Finally, the relationship between lipid composition and clinical outcome was analyzed according to patients′ age and BMI.Results:(1) Comparing the pre-matching dyslipidemia group with the normal blood lipids group, the BMI of the dyslipidemia group was significantly higher than that of the normal blood lipids group [(23.5±2.4) vs (22.4±2.7) kg/m 2], and the embryo implantation rate was significantly lower than that of the normal blood lipids group [13.6% (8/59) vs 27.3% (36/132)], the differences were statistically significant (both P<0.05). (2) There were no significant differences in years of infertility, number of pregnancies, number of abortions, number of transplanted embryos, protocol of endometrial preparation, endometrial thickness on transplantation day and high quality embryo rate between the two groups, through propensity score matching (all P>0.05). The biochemical pregnancy rate [28.6% (10/35)], embryo implantation rate [13.6% (8/59)] and live birth rate [20.0% (7/35)] in dyslipidemia group were significantly lower than those in the normal blood lipids group ( P<0.05). The clinical pregnancy rate was lower than that of the normal blood lipids group ( P>0.05). (3) The results of stratified analysis showed that the level of HDL in the clinically non-pregnant group was significantly lower than that in the pregnant group in patients ≤ 35 years old [(1.5±0.3) vs (1.8±0.5) mmol/L; P<0.05]. In the overweight recipient patients, the level of HDL of the clinically non-pregnant group was lower than that of the pregnant group ( P>0.05). Conclusions:Dyslipidemia significantly reduces the biochemical pregnancy rate, embryo implantation rate and live birth rate in patients with receiving donor eggs. Especially in patients aged ≤35 years old, the reduction of HDL is closely related to adverse pregnancy outcomes.

Exposure to ionizing radiation intervenes in genomic stability and gene expression,resulting in the disruption of normal metabolic processes in cells and organs by causing complex biolog-ical responses.Altered genomic variations,gene expression and metabolite concentrations in blood or tissue samples reflect systemic radiation damage.With the application of new techniques and exten-sive study on the mechanisms for ionizing radiation damage,related indicators such as chromosomal variation,gene expression,lipid and metabolism are being recognized and promise to be the markers for early diagnosis and prognosis of radiation exposure.Therefore,this article reviews recent progress in and potential applications of biomarkers related to ionizing radiation injury.

Chronic low-back pain (CLBP) is one of the most common pain conditions. Current clinical guidelines for low-back pain recommend acupuncture for CLBP. However, there are very few high-quality acupuncture studies on CLBP in older adults. Clinical acupuncture experts in the American Traditional Chinese Medicine Association (ATCMA) were interested in the recent grant on CLBP research announced by the National Center for Complementary and Integrative Health. The ATCMA experts held an online discussion on the subject of real-world acupuncture treatments for CLBP in older adults. Seven participants, each with more than 20 years of acupuncture practice, discussed their own unique clinical experience while another participant talked about the potential mechanism of acupuncture in pain management. As a result of the discussion, a picture of a similar treatment strategy emerged across the participants for CLBP in older adults. This discussion shows that acupuncture may have complicated mechanisms in pain management, yet it is effective for the treatment of chronic pain involving maladaptive neuroplasticity; therefore, it should be effective for CLBP in older adults.
