Objective:
To explore the effects of intergenerational parent-child separation on internalizing and externalizing behavioral problems among rural preschoolers aged 3-6 years, so as to provide empirical evidence for formulating targeted intervention strategies and blocking the intergenerational transmission of parent-child separation.
Methods:
From March to June, 2024, ten kindergartens were selected from rural areas of Nanling County, Wuhu City, Anhui Province, and 2 279 preschool children aged 3- 6 years, along with their fathers, mothers and primary caregivers, were recruited for survey by cluster convenient sampling method. Children s fathers and mothers reported their own childhood parent-child separation information separately. Information on the children s history of psychological and behavioral problems was reported by the primary caregivers. Information of internalizing and externalizing behavioral problems in preschool children was reported with Strengths and Difficulties Questionnaire (SDQ).The Chi square test was used to compare the differences in the detection rates of psychological and behavioral problems among children with different intergenerational continuity of parent-child separation. Binary Logistic regression model was applied to analyze the association between intergenerational continuity of parent-child separation and internalizing and externalizing behavioral problems in preschool children.
Results:
The detection rate of internalizing behavioral problems was 27.5% and externalizing behavioral problems was 19.1% among rural preschool children. There were significant differences in internalization behavior, externalization behavior, hyperactivity impulse and peer communication problems among preschool children in different types of parent-child separation groups( χ 2=14.29, 8.80, 17.26, 13.84, all P <0.05). Binary Logistic regression analysis showed that after adjusting for covariates such as children s gender, birth weight, and delivery mode, compared with children without separation, intergenerational continuity of parent-child separation group( OR =1.95), only child separation( OR =1.74) were associated with significant higher risk of conduct problems(both P <0.05). Parent-child separation intergenerational continuation groups( OR =1.68), only child separation( OR = 1.47) were associated with significant higher risk of peer problems(both P <0.05). Both types of parent-child separation experiences significantly increased the risk of children s prosocial behavior problems,among them, the intergenerational continuation group was 1.99 times that of the control group ( OR =1.99), and the childhood only separation group was 2.09 times that of the control group ( OR =2.09)(both P <0.05). Compared with children whose parents and children had no experience of parent-child separation, children in the intergenerational continuation group of parent-child separation had increased risks of both internalizing and externalizing behavior problems ( OR =1.53, 1.65, both P <0.05).
Conclusion
All types of parent-child separation are associated with internalizing and externalizing behavioral problems among rural children aged 3 to 6 years.

Objective:
To investigate the impact of intergenerational parent-child separation (PCS) on allergic diseases among rural preschool children, providing theoretical guidance for developing targeted public health interventions.
Methods:
From March to June 2024, 10 kindergartens were selected from Nanling, Wuhu City, Anhui Province. A total of 2 279 children aged 3-6 years and their parents/primary caregivers participated in the survey by a combination of convenience sampling and cluster sampling method. Children s fathers and mothers reported the experiences of PCS during their childhood. The children s PCS experiences and allergies were reported by their primary caregivers. The International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was used to supplement the allergies (allergic asthma, allergic rhinitis and atopic dermatitis). Analysis of variance (ANOVA) and Chi square tests were used to compare differences between children in different PCS groups. Logistic regression models assessed the association between PCS and the risk of allergic diseases in preschool children.
Results:
Among the preschoolers enrolled, the prevalence of allergic diseases in only parent-child separation group in childhood, only child separation group, and the intergenerational continuity of PCS groups were significantly higher than those of the none separation group (38.0%, 41.8%, 48.1%,30.4%; χ 2=40.45, P < 0.01 ). After adjusting for covariates including child age, sex and body mass index, Logistic regression model revealed that compared to children in the group without PCS, those in the only parent-child separation in childhood( OR =1.43, 95% CI =1.06-1.94), only child separation ( OR =1.82, 95% CI =1.22-2.71), and intergenerational continuity of PCS ( OR =2.33, 95% CI =1.68-3.24) exhibited higher allergic disease risk (all P <0.05).
Conclusions
Intergenerational continuity of PCS is related to the increased risk of allergies in preschool children. The multigenerational accumulation of adverse effects from PCS underscores the importance of breaking the cycle of disadvantage across generations.

OBJECTIVE To investigate the induction of apoptosis in hepatocellular carcinoma cells by polyphyllin 9 (PP9) through the regulation of the Fas/Fas ligand (FasL) signaling pathway, and its inhibitory effect on the growth of transplanted tumor in nude mice. METHODS Based on the screening of cell lines and intervention conditions, HepG2 cells were selected as the experimental subject to investigate the effects of 2 μmol/L and 4 μmol/L PP9 treatment on cell colony formation activity, apoptosis rate, as well as the protein expressions of Fas, FasL, cleaved caspase-8 and cleaved caspase-3. Additionally, Fas inhibitor KR- 33493 was introduced to investigate the underlying mechanism of PP9’s anti-hepatocellular carcinoma activity. Using HepG2 cell tumor-bearing nude mice model as the object, and 5-fluorouracil (20 mg/kg) as the positive control, the effects of 10 mg/kg PP9 on tumor volume, tumor mass, and the protein expressions of the nuclear proliferation-associated antigen Ki-67 and cleaved caspase-3 in tumor-bearing nude mice were investigated. RESULTS Compared with the control group, 2, 4 μmol/L PP9 significantly decreased the number of clones and the clone formation rate of cells, but significantly increased the apoptosis rate, the protein expressions of Fas, FasL, cleaved caspase-8 and cleaved caspase-3 (P<0.05 or P<0.01). However, the combination of Fas inhibitor KR-33493 could significantly reverse the effect of PP9 on the up-regulation of proteins related to the Fas/FasL signaling pathway (P<0.01). Compared with the control group, the tumor volume (on day 27), mass and protein expression of Ki- 67 in nude mice of the PP9 group were significantly decreased, while the protein expression of cleaved caspase-3 was significantly increased (P<0.01). CONCLUSIONS PP9 can induce apoptosis of HepG2 cells by activating the Fas/FasL signaling pathway. Meanwhile, PP9 can also effectively inhibit the growth of transplanted tumors in nude mice.

Pseudorabies (PR) is an infectious disease caused by the pseudorabies virus (PRV), affecting various domesticated and wild animals. Since pigs are the only natural hosts of PRV, PR poses a serious threat to the pig farming industry. Currently, PR is primarily prevented through vaccination with inactivated vaccines or genetically modified attenuated live vaccines. Developing safe and effective genetically engineered vaccines would facilitate the eradication and control of PR. In this study, the PRV vaccine strain Bartha-K61 was used as the reference strain. The gB protein was expressed via the baculovirus-insect cell expression system. Non-denaturing gel electrophoresis confirmed that the gB protein could form a trimeric structure. The purified gB protein was used to immunize mice, and the immune effect was evaluated by a challenge test. The results showed that the gB antigen induced a strong immune response in mice, with the serum-neutralizing antibody titer above 1:70. The lymphocyte stimulation index reached more than 1.29, and the level of (interferon gamma, IFN-γ) release was higher than 100 pg/mL. After immunization, mice were challenged with the virus at a dose of 104 TCID₅₀/mL, 200 μL per mouse, and the clinical protection rate was 100%. Immunohistochemistry, histopathological section, and tissue viral load results showed that the pathological damage and viral load in the gB-immunized group were significantly lower than those in the PBS group. In summary, the gB protein obtained in this study induced strong humoral and cellular immune responses in mice, laying a foundation for developing a recombinant gB protein subunit vaccine.

OBJECTIVES:
To study the clinical characteristics of rashes induced by trimethoprim-sulfamethoxazole (TMP-SMZ) in children treated for pertussis and to inform safe medication practices.
METHODS:
A retrospective analysis was conducted on 238 children diagnosed with pertussis and treated with TMP-SMZ at Wuhu First People's Hospital from January to August 2024. The incidence and clinical features of rashes were summarized.
RESULTS:
Of 238 children, 34 (14.3%) developed rashes; 19 (55.9%) were boys, and the 5 to <10-year age group accounted for the highest proportion (70.6%, 24/34). A history of allergic disease was present in 50.0% (17/34). Rashes typically appeared on or after day 7 of therapy (82%, 28/34) and were predominantly erythematous or maculopapular eruptions (97%, 33/34); 71% (24/34) were pruritic. Fever occurred in 56% (19/34); among those who were tested for respiratory viruses, 77% (10/13) were positive for viruses such as rhinovirus and adenovirus. After discontinuation of TMP-SMZ, rashes resolved within 3 days in 97% (33/34) of patients (41% within 1 day; 56% within more than 1 but within 3 days). There was no significant difference in rash incidence between photoprotection and non-photoprotection groups (P>0.05).
CONCLUSIONS
TMP-SMZ for pertussis can induce rashes, particularly in children aged 5 to <10 years. The eruption is usually a pruritic erythematous or maculopapular rash, with over half of cases accompanied by fever and frequent concomitant viral infections. Most rashes resolve within 3 days after drug withdrawal. The potential association between the rash and sun exposure warrants further investigation.

OBJECTIVE:
To investigate the antidepressant effects of Xiaoyao Pill (XYP) by exploring its interactions with gut microbiota and tryptophan metabolism.
METHODS:
Utilizing network pharmacology, the functional substance groups, key targets, and pathways of XYP in the treatment of depression were identified. The chronic unpredictable mild stress (CUMS) protocol was implemented in male Sprague-Dawley rats to establish depression model. Thirty rats were randomly divided into 3 groups according to their body weight (10 for each): control, CUMS and XYP groups (1.8 g/kg). After 28-day interventions, behavioral phenotyping including sucrose preference test (SPT) and open field test (OFT) were performed. Biochemical validation encompassed enzyme-linked immunosorbent assay for serum cortisol, hematoxylin-eosin histopathology, and immunohistochemistry. Liquid chromatography-mass spectrometry was utilized to profile serum metabolites, while fecal samples underwent metagenomic sequencing for gut microbiota characterization.
RESULTS:
Network pharmacology studies predicted that key components can protect the nervous system by regulating inflammatory pathways through the blood-brain barrier. SPT and OFT showed that XYP treatment significantly ameliorated depressive-like behaviors (all P<0.05). XYP treatment also restored hippocampal neuronal density, increased serum neurotransmitter levels of neurotransmitters such as 5-hydroxytryptamine and vasoactive intestinal peptide, and while suppressing inflammatory markers such as tumor necrosis factor-alpha, interleukin-1 beta (IL-1 β), and IL-6 (all P<0.05). Metagenomics revealed significant restructuring of gut microbiota, notably the regulation of Parabacteroides distasonis (P<0.05). Non-targeted metabolomics analysis showed that the level of metabolites in the tryptophan and kynurenine pathway significantly changed (variable importance in the projection >1, P<0.05), and the change of metabolic flux was significantly correlated with behavioral improvement (P<0.05).
CONCLUSIONS
XYP exerts antidepressant effects by increasing neurotransmitter levels, reducing inflammatory makers and modulating Parabacteroides distasonis. Through further exploration of metabolomics, we found that XYP may play a protective role in depression by regulating tryptophan metabolism.

OBJECTIVES:
To explore the bioactive components in Jiawei Xiaoyao Pills (JWXYP) and their mechanisms for alleviating depression-like behaviors.
METHODS:
The active compounds, key targets, and pathways of JWXYP were identified using TCMSP and TCMIP databases. Thirty-six SD rats were randomized equally into 6 groups including a control group and 5 chronic unpredictable mild stress (CUMS)-induced depression groups. After modeling, the 5 model groups were treated with daily gavage of normal saline, 1.8 mg/kg fluoxetine hydrochloride (positive control drug), or JWXYP at 1.44, 2.88, and 4.32 g/kg. The depression-like behaviors of the rats were evaluated using behavioral tests, and pathological changes in the liver and hippocampus were examined with HE staining. The biochemical indicators in the serum and brain tissues were detected using ELISA. Serum metabolomics analysis was performed to identify the differential metabolites using OPLS-DA, and gut microbiota changes were analyzed using 16S rDNA sequencing.
RESULTS:
Network pharmacology revealed that menthone and paeonol in JWXYP were capable of penetrating the blood-brain barrier to regulate inflammatory pathways and protect the nervous system. In the rat models subjected to CUMS, treatment with JWXYP significantly improved body weight loss, sucrose preference and open field activities, reduced liver inflammation, alleviated structural changes in the hippocampal neurons, decreased serum levels of TNF‑α, IL-1β, IL-6 and LBP, and increased 5-HT and VIP concentrations in the serum and brain tissue, and these effects were the most pronounced in the high-dose group. Metabolomics analysis showed changes in such metabolites as indole-3-acetamide and acetyl-L-carnitine in JWXYP-treated rats, involving the pathways for bile acid biosynthesis and amino acid metabolism. 16S rDNA analysis demonstrated increased gut microbiota diversity and increased abundance of Lactobacillus species in JWXYP-treated rats.
CONCLUSIONS
JWXYP alleviates depression-like symptoms in rats by regulating the neurotransmitters, inhibiting inflammation and oxidation, and modulating gut microbiota.

Objective:To explore the impact mechanism of strategic human resource management (SHRM) capabilities in hospital clinical departments on departmental organizational performance, providing references for improving the overall performance of hospitals.Methods:The research subjects were 46 clinical departments of a tertiary public hospital in Beijing. Using a stratified sampling method, at least one middle-level manager was selected from each department, and 30% of the medical staff were randomly sampled from each professional title level within the department. A self-made questionnaire was used to investigate the SHRM capabilities of each department from September to December 2023. The organizational performance of clinical departments was assessed using the departmental performance evaluation system established by the hospital. First, the performance target values for each department in 2023 were set based on the historical data from 2020 to 2022. Then, the actual performance evaluation data of 2023 were compared with the target values to calculate the achievement rate or deviation. Finally, the comprehensive performance scores of each department were calculated by weighting. The performance scores of the departments in 2023 were used as the outcome variable, while SHRM capabilities, department size, number of beds, and whether the department was a key department were used as antecedent condition variables. Fuzzy-set qualitative comparative analysis (fsQCA) was employed to explore the combinations of antecedent conditions that lead to high and low organizational performance in clinical departments.Results:A total of 1 391 valid questionnaires were collected. The weighted average score of SHRM capabilities in clinical departments was (4.23±0.27) points, and the total score of organizational performance evaluation in 2023 was 70.75 (52.50, 79.47) points. The consistency of each antecedent condition variable did not reach the critical value of 0.90, indicating that none of them were sufficient to be a necessary condition for high or low organizational performance in the departments. Two pathways to high organizational performance and two pathways to low organizational performance were identified. The solution consistency for the high organizational performance pathway was 0.83, with a coverage of 0.35, and both core conditions, acquisition capability and maintenance capability, were present. The solution consistency for the low organizational performance pathway was 0.85, with a coverage of 0.08, and the core conditions, development capability, was absent.Conclusions:Different combinations of antecedent condition variables, including the strategic human resource management capability of clinical departments, had varying impacts on the organizational performance of clinical departments. The possession of human resource acquisition, maintenance, and development capabilities by clinical departments was an essential condition for achieving high organizational performance. It is recommended to strengthen the construction of these three capabilities and emphasize the coordinated development of human resource management capabilities to enhance the organizational performance of clinical departments.
