Children's Social Behaviors: Developmental Mechanisms and Implications.

During the socialization process in family and school contexts, children display a wide variety of social behaviors with parents and peers. Yet the developmental trajectory, the predictors and outcomes, and the neural basis of those social behaviors are largely under-investigated. To address these problems, we invited experts in the field to submit their latest findings to tell this story. The current Special Issue is a collection of papers highlighting the complexity for various social behaviors, with a focus on the complex mechanisms that link social behaviors to child socio-emotional adjustment and mediating/moderating factors among the associations. Thirteen papers illustrate empirical work in the field, two papers present new methodological concerns, and one paper that provides a comprehensive review of the literature.

The reciprocal relationship between child maltreatment and children's bullying victimization in China.

Children who experience physical and psychological maltreatment within their family are more likely to become victims of abuse outside the family. In Chinese culture, children's victimization may also be a precursor to parenting behaviors. Nevertheless, the reciprocal relationship between child maltreatment and children's bullying victimization remains unclear, particularly in Chinese culture. This study aimed to evaluate the reciprocal association between child maltreatment and children's bullying victimization in China, as well as its gender differences. A total of 891 children aged 8-11 years in China participated in the study at four time points. The potential reciprocal link was examined using a cross-lagged model. The results indicated that physical abuse predicted children's bullying victimization across four time points, while physical neglect predicted children's bullying victimization during the first three time points. The effects of emotional abuse and neglect were negligible. Conversely, children's bullying victimization consistently predicted various types of parental maltreatment over time. Some gender differences in the relationship were found. The findings emphasized a reciprocal relationship between child maltreatment within the family and children's bullying victimization at school. Understanding the cyclical patterns between child maltreatment and bullying victimization may help improve family education approaches and reduce children's bullying victimization.

Clinical Reasoning: A 30-Year-Old Woman Presenting With Rapidly Progressive Dementia and Extreme Hypoglycorrhachia.

A 30-year-old woman presented with rapidly progressive dementia 1 month after the coronavirus disease 2019 infection. Repeated CSF analysis showed extreme hypoglycorrhachia, while cultures, metagenomic next-generation sequencing, and cytopathology testing of CSF were negative. Laboratory investigations for possible etiologies revealed elevated blood ammonia and cancer antigen 125. Brain MRI demonstrated bilateral symmetric diffuse cortical lesions with mild hyperintensity on T1-weighted image and postcontrast enhancement. A more thorough history and specific examinations subsequently indicated an underlying etiology. This case provides an approach for evaluating young patients with rapidly progressive dementia, extreme hypoglycorrhachia, and diffuse CNS lesions, highlighting the importance of considering a broad differential diagnosis.

How to survive the long night? Longitudinal relationship between sleep problems and suicidal behavior among adolescents: The serial mediating roles of negative emotion, self-control, and nonsuicidal self-injury.

OBJECTIVE: Sleep problems are a significant risk factor for identifying and preventing suicidal involvement among adolescents. However, there is limited evidence to assess the underlying mechanisms between them. This study investigated the longitudinal relationship between sleep problems and suicidal behavior and examined whether this relationship was moderated by negative emotions, low self-control, and nonsuicidal self-injury (NSSI). METHODS: From December 2020 onward, we assessed 1214 Chinese secondary school adolescents (60.7% were boys, aged 13-19 years) three times, 6 months apart. RESULTS: In the direct effects model, sleep problems were found to have a positive impact on adolescent suicidal behavior. In the indirect effects model, we observed that sleep problems were associated with an elevated risk of suicidal behavior through several pathways: one-mediator path of negative emotions, low self-control, and NSSI, respectively; two-mediator path of negative emotions via low self-control, negative emotions via NSSI, and low self-control via NSSI, and three-mediator path from negative emotions to NSSI via low self-control. CONCLUSIONS: This longitudinal study provides evidence that sleep problems in adolescents may increase suicidal behavior by exacerbating negative emotions, weakening self-control, and promoting NSSI. The findings suggest sleep problems should be addressed in suicide prevention and intervention efforts for adolescents.

Resistance of the Ginseng Gray Mold Pathogen, Botrytis cinerea, to Boscalid and Pyraclostrobin Fungicides in China.

Gray mold caused by Botrytis cinerea severely threatens the yield of ginseng (Panax ginseng). Various categories of fungicides have been utilized to control gray mold on this crop. In this study, the resistance of 102 isolates of B. cinerea from 11 commercial ginseng-growing regions in China to fungicides was examined. A total of 32.4% were resistant to boscalid, with EC50 values that ranged from 12.26 to 235.87 µg/ml, and 94.1% were resistant to pyraclostrobin, with EC50 values that ranged from 5.88 to 487.72 µg/ml. Except for sdhA and sdhD, the amino acid substitutions of P225F, P225L, N230I, H272Y, and H272R in the sdhB subunit from 24 (4 sensitive [S] and 20 resistant [R]), 5 (1 S and 4 R), 1 (S), 1 (R), and 8 (4 S and 4 R) strains, respectively, and the concurrent amino acid substitutions of G85A + I93V + M158V + V168I in the sdhC subunit from 5 (4 S and 1 R) strains were identified. A G143A substitution in cytochrome b was identified in 96 isolates that were resistant to pyraclostrobin and three that were sensitive to it. The Bcbi-143/144 intron was identified in the other three isolates sensitive to pyraclostrobin, but it was absent in the isolates that harbored the G143A mutation. The results showed that the populations of B. cinerea on ginseng have developed strong resistance to pyraclostrobin. Therefore, it is not recommended to continue using this fungicide to control gray mold on P. ginseng. Boscalid is still effective against most isolates. However, to prevent fungicide resistance, it is recommended to use a mixture of boscalid with other categories of fungicides.

A reciprocal relationship between parental maltreatment and child bullying perpetration in China.

This study aimed to examine the longitudinal reciprocal relationship between parental maltreatment and child bullying perpetration from middle childhood to early adolescence in China and the associated gender differences. Eight hundred ninety-one children completed a battery of questionnaires at four time points. A random-intercept cross-lagged model was established. The results indicated that at the between-person level, child bullying perpetration was positively associated with physical and psychological maltreatment. At the within-person level, there was a significant association between an increase in bullying perpetration and an increase in parental psychological and physical maltreatment across the four time points. Conversely, an increase in physical maltreatment led to an increase in child bullying perpetration from T1 to T2, while an increase in psychological maltreatment resulted in an increase in child bullying perpetration from T1 to T2 and T2 to T3. Furthermore, an increase in physical maltreatment increased boys' bullying perpetration but decreased that in girls from T2 to T3. These findings provide inspiration for future family education and anti-bullying interventions in schools.

First Report of Sclerotinia Rot Caused by Sclerotinia sclerotiorum on Artemisia capillaris in China.

Artemisia capillaris (Asteraceae) is an annual herb found in ˃10 provinces in China. It is cultivated on ˃670 ha, with annual production around 2,500 tons. Its shoot is used in traditional Chinese medicine (Liu et al. 2021). From April to May 2023, Sclerotinia rot symptoms were seen at the Institute of Medicinal Plant Development (40.04°N, 116.28°E), Beijing, China. Disease incidence was up to 10% in the field through investigation of 300 plants. Initial symptoms were irregular tan-brown lesions (0.5 to 5.0 mm) that expended to circumferential necrosis on the roots and basal stem, aerial mycelia and sclerotia were developed on them. The leaves and stem tips were withered and droopy in severe cases. Twelve symptomatic primary roots of 12 plants from two sites were cut into 5 × 5 mm pieces, surface sterilized with 75% ethanol for 30 s and 5% NaClO for 60 s, rinsed with distilled water for three times, dried with sterile filter paper, put on potato dextrose agar (PDA), and incubated at 25°C in the dark for 2 days. Two Sclerotinia-like isolates were obtained using the hyphaltip method. White aerial mycelia were sparse and appressed for isolate YC1-3 and dense for isolate YC1-7. After incubated at 25°C in the dark for 15 days, 10 to 25 sclerotia were developed near the colony margin. Sclerotia of isolate YC1-3 were 1.0 to 3.9 × 1.2 to 4.5 (mean 1.8 × 2.2) mm (n = 60), ovoid or arc-shaped. Sclerotia of isolate YC1-7 were 1.5 to 3.4 × 2.7 to 9.2 (mean 2.3 × 4.3) mm (n = 60), ovoid, dumbbell shaped or curved. The isolates were identified as Sclerotinia sclerotiorum based on morphology (Maas 1998). To further identify the pathogens, molecular identification was performed with isolates YC1-3 and YC1-7. DNA of the two isolates were extracted by the cetyltrimethylammonium bromide (CTAB) method. Polymerase chain reaction was performed with primers ITS1/ITS4 for the internal transcribed spacer (ITS) region (Choi et al. 2020; White et al. 1990) and primers G3PDHfor/G3PDHrev for the glyceraldehyde 3-phosphate dehydrogenase (G3PDH) gene (Garfinkel. 2021). BLAST search analysis revealed that the ITS sequence (GenBank OR229758 and OR229762) was ≥99% similar to S. sclerotiorum (MN099281, MZ379265, KX781301, etc.), and the G3PDH sequence (OR778388 and OR761975) was too (MZ493894, JQ036048, OQ790148, etc.). Phylogenetic trees were computed with ITS and G3PDH sequences using the Maximum Likelihood in MEGA 11. Nine two-month-old seedlings of A. capillaris were used to test pathogenicity. The epidermis layer of each primary root was slightly wounded (2 × 2 mm, 1 mm deep) using a sterile dissecting blade. Three plants were inoculated with mycelial plugs (5 mm in diameter) of YC1-3 and YC1-7 that cultured on PDA for 7 days. Control plants were inoculated with sterile PDA plugs. All seedlings were then incubated at 25oC and 90% relative humidity. After isolate YC1-7 inoculation 3 days and isolate YC1-3 inoculation 5 days, inoculated roots had symptoms like those in the field, controls had no symptoms. S. sclerotiorum was consistently re-isolated from diseased roots, fulfilling Koch's postulates. Diseases caused by S. sclerotiorum have been reported threatens several important economical crops (Marin and Peres 2020; Guan et al. 2022). To our knowledge, this is the first report of S. sclerotiorum causes Sclerotinia rot on A. capillaris. To avoid of significant economic losses, it is urgent to establish an effective disease-management strategy.

Long duration of atrial high-rate episode is more favorable in predicting ischemic stroke than high CHA2 DS2 -VASc score.

OBJECTIVE: This study aimed to explore the roles of duration and burden of atrial high-rate episode (AHRE) on ischemic stroke in patients with pacemaker implantation. METHODS: Patients with pacemaker implantation for bradycardia from 2013 to 2017 were consecutively enrolled. Data such as gender, age, combined diseases, type of AF, left atrial size, left ventricular size, left ventricular ejection fraction, CHA2 DS2 -VASc score, and anticoagulants were collected. The burden and duration of AHRE based on different interval partition were also recorded in detail to evaluate the impacts on ischemic stroke. Cox regression analysis with time-dependent covariates was conducted. RESULTS: A total of 220 patients with AHRE were enrolled. The average follow-up time was 48.42 ± 17.20 months. Univariate regression analysis showed that diabetes (p = .024), high CHA2 DS2 -VASc score (≥ 2) (p = .021), long mean AHRE burden (p = .011), long maximal AHRE burden (p = .015), long AHRE duration lasting≥48 h (p = .001) or 24 h (p = .001) or 12 h (p = .005) were prone to ischemic stroke. Further multivariate regression analysis showed that long duration of AHRE (≥48 h) (HR 10.77; 95% CI 3.22-55.12; p = .030) were significantly correlated with stroke in patients with paroxysmal AF. There was no significant correlation between the type of AF and stroke (p = .927). CONCLUSION: The longer duration of AHRE (≥48 h) was more favorable in predicting ischemic stroke than high CHA2 DS2 -VASc score (≥2).

Harsh Childhood Discipline and Developmental Changes in Adolescent Aggressive Behavior: The Mediating Role of Self-Compassion.

Harsh discipline during childhood (psychological aggression and corporal punishment) has been found to be an early risk factor for adolescent aggressive behavior. However, previous studies have mainly examined the relationship between harsh discipline as a whole and the level of adolescent aggressive behavior. This study investigates the effects of childhood psychological aggression and corporal punishment on the initial levels and rate of change in adolescent aggressive behavior, as well as the mediating role of self-compassion in this relationship. Using cluster sampling, a three-wave follow-up assessment was conducted on 1214 high-school students (60.7% boys; mean age at Wave 1 = 15.46 ± 0.71). The results showed that childhood psychological aggression and corporal punishment had a positive predictive effect on the development level of adolescent aggressive behavior. However, only childhood psychological aggression significantly directly attenuated the decline rate of adolescent aggressive behavior. In addition, both childhood psychological aggression and corporal punishment indirectly affected the initial levels and growth rate of adolescent aggressive behavior through self-compassion. These findings could provide potential targets for prevention and intervention programs aimed at improving aggressive behavior in Chinese adolescents.

First Report of Corynespora cassiicola Causing Septoria Leaf Spot on Scutellaria baicalensis in China.

Scutellaria baicalensis Georgi. is a perennial herb in the Lamiaceae family, with a distribution in more than 10 provinces in China. At the current time, the cultivation area of S. baicalensis in China exceeds 58,000 hectares, with annual production approaching 28,000 tons. As a traditional Chinese herbal medicine, the root of S. baicalensis has many applications, such as anti-inflammatory, anti-neuroinflammatory and neuroprotective, anticancer, antiviral, antibacterial, and antioxidant activities, and is effective in treatment of colitis, hepatitis, pneumonia, respiratory infections, and allergic diseases. (Jang et al. 2023; Liu et al. 2023). From August to September 2022, septoria leaf spot symptoms were observed at the Institute of Medicinal Plant Development (40.04°N, 116.28°E), Beijing, China, and the incidence of this disease was up to 20% in the field through more than two weeks of continuous investigation. Initial symptoms on leaves were observed as small, dark-brown spots (0.5 to 2.0 mm), which then expanded to irregular lesions with a pale gray center surrounded by a black ring with a dark-brown edge and light brown halo (Fig. 1A1-A3). Plants were defoliated and withered in severe cases. Thirty-six symptomatic leaves of 12 diseased plants from three experimental sites were cut into 5 × 5 mm pieces, and surface sterilized with 75% ethanol for 30 s followed by 5% NaClO solution for 45 s, rinsed with sterile water three times, dried with sterile filter paper, and subsequently placed on potato dextrose agar (PDA) medium and incubated at 25°C in dark for two days. Isolates were purified by transferring hyphal tips to new PDA plates and incubated at 25°C in dark. Finally, eight isolates (A1, B3, D1, F2, E2, a4, e4 and f1) with similar colonial morphological characteristics were obtained. Colonies on PDA exhibited dense, downy, and white to grayish-green aerial mycelia and the reverse of colonies showed dark-brown in the center and grayish on the edge (Fig. 1D, E). Conidia were solitary or catenate, pale brown, obclavate to cylindrical, apex obtuse (Fig. 1B, C). The isolates were divided into two categories by examining 100 conidia (50 of each isolate), represented by isolates D1 and e4. Conidia of D1 measured 5.4 to 75.8 µm × 2.1 to 6.8 µm, mean 26.9 × 4.4 µm, had 0 to 6 pseudosepta, with 0 to 3 pseudosepta observed in 88% of conidia. Conidia of e4 measured 20.3 to 103.4 µm × 2.0 to 7.9 µm, mean 41.9 × 4.8 µm, had 0 to 6 pseudosepta, with 2 to 5 pseudosepta observed in 90% of conidia. These isolates were identified as Corynespora cassiicola based on morphology (Ellis 1971). DNA of the two isolates (D1 and e4) was extracted by the cetyltrimethylammonium bromide (CTAB) method, and internal transcribed spacer (ITS) region of rDNA, translation elongation factor 1 alpha (TEF1-α), and beta-tubulin (TUB2) gene were amplified, using the primers ITS1/ITS4 (Bandi et al. 2022), EF1-728F/EF-986R (Wang et al. 2021), and Bt2a/Bt2b (Glass and Donaldson 1995), respectively. Sequences of ITS OQ991339 (524 bp) and OR044050 (533 bp) shared 99.8% identity to C. cassiicola, with a 99% coverage to MT228951 (536 bp) and OQ991340 (546 bp) in GenBank. Sequences of TEF1-α OR047441 (304 bp) and OR047443 (306 bp) shared 99.3% identity to C. cassiicola, with a 98% and 99% coverage to ON381927 (300 bp) and ON381933 (301 bp) in GenBank, respectively. Sequences of TUB2 OR047449 (427 bp) and OR047451 (427 bp) shared 99.53% identity to C. cassiicola, with a 99% and 98% coverage to MN604075 (442 bp) in GenBank, respectively. Phylogenetic trees were computed with ITS, TEF1-α, and TUB2 sequences in MEGA 11 using the Neighbor-Joining (NJ) method (Fig. 2). The results showed that the two isolates were C. cassiicola with more than 90% bootstrap support (1000 replicates). Nine 2-year-old seedlings of S. baicalensis were used for the pathogenicity assay. Three leaves from each plant were punctured with flame-sterilized needles, and inoculated with mycelial plugs (5 mm in diameter) of D1 and e4. Plants inoculated with sterile PDA plugs were used as control. All the inoculated seedlings were incubated at 25 oC and 90% relative humidity. About 3 to 4 days after inoculation, similar symptoms to those observed in the field were present on leaves inoculated with D1 and e4, while no symptoms were observed in the uninoculated control seedlings (Supplementary Fig. 1). Isolates with vigorous, downy, and white to grayish-green aerial mycelia were reisolated from the diseased leaves inoculated with D1 and e4 and identified as C. cassiicola by DNA sequencing, fulfilling Koch's postulates. Based on morphological and multilocus phylogenetic results, these isolates were identified as C. cassiicola, a pathogen that threatens several important crops (Dixon et al. 2009; Zhang et al. 2018; Xie et al. 2021). To our knowledge, this is the first report of C. cassiicola as the causal pathogen of septoria leaf spot on S. baicalensis in China, which poses a potential threat to the production of S. baicalensis.

Longitudinal relationship between child maltreatment, bullying victimization, depression, and nonsuicidal self-injury among left-behind children in China: 2-year follow-up.

BACKGROUND: Left-behind childre (LBC) in China are deeply concerned by society because of their high risk of emotional and behavioral problems. Depression and nonsuicidal self-injury are the most harmful and worrying negative emotional and behavioral problems in LBC. Unfortunately, LBCs are in unfavorable environments for a long time and are prone to negative interpersonal interactions. Child maltreatment and bullying victimization, as the two most typical negative interpersonal interactions in family and school environments, maybe the key risk factors for depression and nonsuicidal self-injury among LBCs. However, we are less known of the longitudinal effects of child maltreatment and bullying victimization on LBC's depression and nonsuicidal self-injury and their underlying mechanisms. AIMS: This study used a two-year longitudinal design with three-time points to investigate the longitudinal effects of child maltreatment and bullying victimization on depression, nonsuicidal self-injury, and the mediating role of negative thoughts and self-compassion. MATERIALS & METHODS: A sample of 592 LBC (390 were males, Mage at time 1 = 9.56, SDage = 0.65; 202 were females, Mage at time 1 = 9.43, SDage = 0.63) completed a set of questionnaires at three-time points. This study used SPSS software (version 25.0) and MPLUS software (version 8.3) for all analyses. RESULTS: (1) Child maltreatment not only affects depression and nonsuicidal self-injury but also affects depression and nonsuicidal self-injury through negative thoughts. Child maltreatment affects depression through self-compassion and does not affect nonsuicidal self-injury. (2) Bullying victimization affects depression and nonsuicidal self-injury through negative thoughts and bullying victimization further affects depression through self-compassion but does not affect nonsuicidal self-injury. CONCLUSION: This study revealed the effects of negative interpersonal interactions (child maltreatment, bullying victimization) on LBC's adverse emotions and behaviors, and their underlying mechanisms, which helps to provide parents, schools, and psychoeducational workers with a new perspective on intervention.

Effect of minimally invasive versus open surgery in hepatectomy on postoperative wound complications in patients with hepatocellular carcinoma: A meta-analysis.

In a meta-analysis, we assessed the impact of different surgical approaches on the outcome of hepatectomy with hepatocellular carcinoma. Four databases, including PubMed, Embase, Cochrane Library, and the Web of Science, have been critically reviewed through the full literature through June 2023. Eleven related trials were examined once they had met the trial's classification and exclusion criteria, as well as the assessment of the quality. A random effects approach was applied to analysis of operative organ infections, and a fixed-effect model was applied to determine the 95% CI and OR. Analysis of the data was done with RevMan 5.3. Our findings indicated that patients undergoing minimally invasive liver cancer surgery had significantly lower risks of surgical organ infection (OR, 0.35; 95% CI, 0.16-0.77; p = 0.009) and wound infection (OR, 0.19; 95% CI, 0.13-0.28; p < 0.001) compared to those undergoing open surgery. There was no heterogeneity observed between the two groups (I2 = 0) in wound infection. Nevertheless, because of the limited number of randomised controlled trials in this meta-analysis, care should be taken and carefully considered in the treatment of these values. Further high-quality studies involving a large number of samples are needed to validate and reinforce the results.

The more you avoid, the worse you will get: a cross-lagged panel model of shyness, mobile phone dependence and depression.

BACKGROUND: The current situation of adolescent depression is relatively serious, and has aroused widespread concern. Aim: This study aimed to examine the relationship between shyness, mobile phone dependence and depression through a 12-month longitudinal survey. METHODS: A total of 1214 adolescents participated in the study. Cross-lagged models were adopted for data analysis. RESULTS: The results showed that significant positive relationships exist among shyness, mobile phone dependence and depression. Shyness at W2 mediated the relationship between mobile phone dependence at W1 and depression at W3. Mobile phone dependence at W2 played a mediating role between depression at W1 and depression at W3. CONCLUSION: This study revealed the possible reciprocal associations between shyness, mobile phone dependence and depression in adolescents. This enlightened us that incorporating shyness and mobile phone dependence interventions into prevention designs for depression in adolescents may be beneficial.

How does parent-child attachment influence left-behind children's loneliness and depression: The mediating roles of peer attachment and teacher-student relationship.

BACKGROUND: Loneliness and depression are common emotional problems among left-behind children, and these emotional problems may have a high correlation with attachment relationships. AIMS: This study aimed to investigate the effects of parent-child attachment on left-behind children's loneliness and depression and the mediating roles of peer attachment and teacher-student relationship and their gender differences. METHODS: Using two waves of data, 614 left-behind children participated in the longitudinal study by completing a series of relevant questionnaire two times (spaced 6 months). RESULTS: The results showed that (1) both father-child attachment and mother-child attachment could negatively predict the loneliness and depression of left-behind children. Further, mother-child attachment has a greater predictive effect on loneliness. (2) Peer attachment played a mediating role in parent-child attachment and left-behind children's loneliness; teacher-student relationship played a mediating role in parent-child attachment and left-behind children's loneliness and depression. (3) The scores of girls were higher than those of boys in the four types of attachment relationships; the mediating role of teacher-student relationship between parent-child attachment and depression was significant only among boys. CONCLUSIONS: This study explored the factors that may have impacts on left-behind children's loneliness and depression as well as its potential mechanism and their gender differences based on the perspective of multiple-attachment theory. These results emphasize the important role of close parent-child attachment in reducing loneliness and depression among left-behind children, as well as the necessary mediating role of peer attachment and teacher-student relationships. These findings provide some valuable recommendations for preventing left-behind children's loneliness and depression.

[Sensitivity baseline establishment and resistance risk assessment of Botrytis cinerea from Panax ginseng to prochloraz].

This study aimed to establish the baseline sensitivity of Botrytis cinerea from Panax ginseng to prochloraz, and ensure the fitness of prochloraz-resistant mutants and the cross-resistance of B. cinerea to prochloraz and commonly used fungicides for the prevention and control of gray mold including boscalid, pyraclostrobin, iprodione, and pyrimethanil. The sensitivity of B. cinerea from P. ginseng to fungicides was determined by the mycelial growth rate method. The prochloraz-resistant mutants were screened out through fungicide domestication and ultraviolet(UV) induction. The fitness of resistant mutants was determined through the stability of subculture, mycelial growth rate, and pathogenicity test. The cross-resistance between prochloraz and the four fungicides was determined by Person correlation analysis. The results showed that all B. cinerea strains tested were sensitive to prochloraz, and the EC_(50) value ranged from 0.004 8 to 0.062 9 µg·mL~(-1), with an average of 0.022 µg·mL~(-1). The sensitivity frequency distribution diagram showed that 89 B. cinerea strains were located within the main peak with a continuous single peak curve, and the average EC_(50) value of 0.018 µg·mL~(-1) was taken as the baseline sensitivity of B. cinerea to prochloraz. The fungicide domestication and UV induction obtained 6 resistant mutants, among which 2 strains were unstable and the other 2 strains showed decreased resistance after multiple generations of culture. Furthermore, the mycelial growth rate and spore yield of all resistant mutants were lower than those of their parents, and the pathogenicity of most mutants was lower than that of their parents. In addition, prochloraz had no obvious cross-resistance with boscalid, pyraclostrobin, iprodione, and pyrimethanil. In conclusion, prochloraz has great potential for controlling gray mold in P. ginseng, and the resistance risk of B. cinerea to prochloraz is low.

Classification, risk factors, and outcomes of patients with progressive hemorrhagic injury after traumatic brain injury.

BACKGROUND: According to the pathoanatomic classification system, progressive hemorrhagic injury (PHI) can be categorized into progressive intraparenchymal contusion or hematoma (pIPCH), epidural hematoma (pEDH), subdural hematoma (pSDH), and traumatic subarachnoid hemorrhage (ptSAH). The clinical features of each type differ greatly. The objective of this study was to determine the predictors, clinical management, and outcomes of PHI according to this classification. METHODS: Multivariate logistic regression analysis was used to identify independent risk factors for PHI and each subgroup. Patients with IPCH or EDH were selected for subgroup propensity score matching (PSM) to exclude confounding factors before evaluating the association of hematoma progression with the outcomes by classification. RESULTS: In the present cohort of 419 patients, 123 (29.4%) demonstrated PHI by serial CT scan. Of them, progressive ICPH (58.5%) was the most common type, followed by pEDH (28.5%), pSDH (9.8%), and ptSAH (3.2%). Old age (≥ 60 years), lower motor Glasgow Coma Scale score, larger primary lesion volume, and higher level of D-dimer were independent risk factors related to PHI. These factors were also independent predictors for pIPCH, but not for pEDH. The time to first CT scan and presence of skull linear fracture were robust risk factors for pEDH. After PSM, the 6-month mortality and unfavorable survival rates were significantly higher in the pIPCH group than the non-pIPCH group (24.2% vs. 1.8% and 12.1% vs. 7.3%, respectively, p < 0.001), but not significantly different between the pEDH group and the non-pEDH group. CONCLUSIONS: Understanding the specific patterns of PHI according to its classification can help early recognition and suggest targeted prevention or treatment strategies to improve patients' neurological outcomes.

Contributions of Multilevel Family Factors to Emotional and Behavioral Problems among Children with Oppositional Defiant Disorder in China.

Oppositional defiant disorder (ODD) is one of the most prevalent childhood mental health disorders and is extremely affected by family factors. However, limited studies have addressed the issue from the perspective of family systems. The current study examines the associations between multilevel family factors (i.e., family cohesion/ adaptability at system level, mother-child and father-child attachment at a dyadic level, and child self-esteem at an individual level) and emotional and behavioral problems among children with ODD in China. The participants were 256 Chinese children with ODD and their parents and class master teachers. A multiple-informant approach and structural equation model were used. The results revealed that system level factors (family cohesion/adaptability) were associated with child emotional and behavior problems indirectly through factors at the dyadic level (mother-child attachment) and the individual level (child self-esteem) in sequence. Mother-child, but not father-child, attachment, mediated the linkage between family cohesion/adaptability and the emotional problems of children with ODD. Moreover, child self-esteem mediated the association between mother-child attachment and child emotional and behavioral problems. The findings of the present study underscored that multilevel family factors are uniquely related to emotional and behavioral problems in children with ODD.

Bidirectional longitudinal relationships between parents' marital satisfaction, parenting stress, and self-compassion in China.

Abundant research has shown that self-compassion robustly contributes to adults' psychological well-being. Meanwhile, a few studies have shown that self-compassion is rooted in early experiences with parents. However, it is unclear whether interactions with partners and children affect adults' self-compassion, and the role of their self-compassion in interactions with significant others. This study examined bidirectional longitudinal relationships between Chinese parents' marital satisfaction, parenting stress, and self-compassion following a three-wave longitudinal design. A sample of 322 Chinese father-mother dyads (father's Mage  = 35.84, SDage  = 5.76; mother's Mage  = 34.32, SDage  = 5.46) completed a set of questionnaires at three time points. The results showed that marital satisfaction positively predicted the fathers' and mothers' self-compassion, while parenting stress did not significantly predict the parents' self-compassion; In contrast, parents' self-compassion did not significantly predict marital satisfaction or parenting stress. Additionally, there was a bidirectional relationship between marital satisfaction and parenting stress in fathers and mothers. Finally, mothers' marital satisfaction positively mediated the relationship between parenting stress and self-compassion/next-stage parenting stress. This study revealed that adults' self-compassion can develop from caring and supportive relationships, including marital relationships. Highlighting key mechanisms of marital satisfaction, such as increasing self-compassion and reducing parenting stress, may contribute to the improvement of adults' mental health.

Why is my world so dark? Effects of child physical and emotional abuse on child depression: The mediating role of self-compassion and negative automatic thoughts.

BACKGROUND: The adverse effects of childhood maltreatment on the mental health of individuals have received increasing attention. However, it is unclear whether the effects of invisible emotional abuse and visible physical abuse differ on child depression and the mediating processes under this relationship. OBJECTIVE: This study aimed to investigate whether self-compassion and negative automatic thoughts mediated the effects of physical abuse and emotional abuse on child depression and the underlying mechanistic differences. PARTICIPANTS AND SETTING: Using a two-wave longitudinal design, a total of 946 elementary school students completed the self-report questionnaires at two-time points, including child abuse, self-compassion, negative automatic thoughts, and depression. METHODS: This study constructed structural equation models (SEM) to examine the mediating role of self-compassion and negative automatic thoughts between emotional/physical abuse and child depression. RESULTS: After controlling for demographic covariates, structural equation modeling (SEM) showed that only physical abuse significantly and positively predicted child depression directly (ß = 0.16, p < 0.01). Emotional abuse was positively associated with child depression through self-compassion (ß = 0.02, p < 0.05) and negative automatic thoughts (ß = 0.02, p < 0.05), while physical abuse influenced child depression only via negative automatic thoughts (ß = 0.07, p < 0.001). CONCLUSIONS: The findings showed a strong association between emotional/physical abuse and child depression, but there were mechanistic differences under these relationships. Therefore, we also need to pay equal attention to the adverse effects of emotional abuse on children.

Longitudinal Relationship Between Bullying Victimization and Depression Among Left-Behind Children: Roles of Negative Thoughts and Self-Compassion.

Background: Left-behind children (LBC) in China have aroused widespread concern in society and the academic field because they have a high risk of psychological problems. For left-behind children, depression is the most serious problem. Bullying victimization has been evidenced as one of the most common causes of children's depression. However, less is known about its longitudinal association and the process for how bullying victimization influences depression among left-behind children. Thus, the presentation aims to explore the mechanisms underlying by considering the roles of left-behind children's negative thoughts and self-compassion. Methods: The 3-wave longitudinal data were collected from a sample of 605 aged 8-11 from central China. We used the Olweus bully and victimization questionnaire, the children's automatic thoughts scale, the depression scale, and the self-compassion scale. Results: Bullying victimization positively predicted the depression level of left-behind children. Negative thoughts and self-compassion mediate the relationship between bullying victimization and depression. In the mechanism of bullying victimization on depression exists gender differences among left-behind children. Conclusion: The present study suggested the association between bullying victimization and left-behind children's depression and revealed the internal mechanism of negative thoughts and self-compassion. These findings provide a new perspective for left-behind children's mental health education and intervention.
