Campus bullying is a universal problem in the world, and it is also the focus of attention of Chinese academia and all walks of life at present. This paper combs the important research literature about campus bullying in China, collates the connotation and types of campus bullying. In addition, this paper analyzes the research achievements and representative viewpoints and summarizes the shortcomings of existing research, including its causes, harms and coping strategies. The following important research fields and topics are analyzed in order to provide new ideas for the further study of this phenomenon.

BackgroundPatients with temporal lobe epilepsy (TLE) frequently complain of poor sleep quality, which is a condition that clinicians are typically neglecting. In this study, Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), and Athens Insomnia Scale (AIS) were used to assess the sleep status of patients with temporal lobe epilepsy (TLE). Simultaneously diffusion kurtosis imaging (DKI) was applied to examine the white matter microstructure abnormalities in patients with TLE and sleep disorders.MethodsTLE patients who have been diagnosed in the cardio-cerebrovascular ward of the Yanan University Affiliated Hospital from October 2020 to August 2021 were recruited. Finally, 51 patients and 30 healthy controls were enrolled in our study, with all subjects completing the sleep evaluation questionnaire and undergoing a DKI examination. Using independent sample t-test, analysis of variance (ANOVA), and Mann-Whitney U test to compare groups.ResultsThirty patients (58.82%) complained of long-term sleep difficulties. The overall differences among the evaluation of AIS, ESS, and PSQI are significant (P = 0.00, P = 0.00, P = 0.03). The scores of AIS, ESS in Left and Right-TLE (L/R-TLE) with sleep disorders, as well as PSQI in L-TLE, are statistically higher than the control group (P = 0.00, P = 0.00, P = 0.00, P = 0.00, P = 0.02). L-TLE with sleep disorders showed decreased MK on affected sides (P = 0.01). However, statistical differences in MD and FA have not been observed (P = 0.34, P = 0.06); R-TLE with sleep disorders showed significantly decreased MK and increased MD on affected sides (P = 0.00, P = 0.00), but FA's statistical difference has not been observed (P = 0.20).ConclusionsTLE patients with sleep disorders have different DKI parameters than individuals who do not have sleep issues. During this process, the kurtosis parameter (MK) was more sensitive than the tensor parameters (MD, FA) in detecting the patient's aberrant white matter diffusion. DKI may be a better choice for in vivo investigation of anomalous craniocerebral water diffusion.

Soybean cyst nematode (SCN, Heterodera glycines) is a chief plant-parasitic nematode of soybean. Application of synthetic chemical nematicides poses negative side effects to human health and the environment. Therefore, the search for a safe and effective approach is more relevant. This study evaluated the effects of Genistein and Daidzein on the physiological index of soybean cyst nematodes, individual morphology, reversal frequency, respiration, and body fluid leaking of second-stage juveniles (J2s) of soybean cyst nematode. The results showed that body length of J2s decreased, while stylet and tail transparent area elongated. Additionally, after the treatment, the body became hollow and shrunken, the J2s stiffened, whereas the reversal frequency decreased dramatically after 24 h of treatment. Moreover, the body fluid leakage was intensified and respiration was inhibited. Oxygen consumption decreased by 86.7 % and 70.1 %, while, in contrast, electrical conductivity increased by 40.1 % and 36 % at 100 μg mL -1 of Genistein and Daidzein, respectively, after 48 h of exposure. The smaller number of J2s in soybean roots, the slower development rate, and the abnormal sexual differentiation were found in greenhouse assay. Thus, Genistein and Daidzein, especially Genistein, have strong effects on the physiological index of soybean cyst nematodes. Moreover, the effects were time and dosage-dependent.
