In recent years, the spread of clubroot disease caused by Plasmodiophora brassicae infection has seriously affected the yield and quality of Brassica juncea (L.) Czern.. The cascade of mitogen-activated protein kinases (MAPKs), a highly conserved signaling pathway, plays an important role in plant responses to both biotic and abiotic stress conditions. To mine the MAPK genes related to clubroot disease resistance in B. juncea, we conducted a genome-wide analysis on this vegetable, and we analyzed the phylogenetic evolution and gene structure of the MAPK gene family in mustard. The 66 BjuMAPK genes identified by screening the whole genome sequence of B. juncea were unevenly distributed on 17 chromosomes. At the genomic scale, tandem repeats led to an increase in the number of MAPK genes in B. juncea. It was found that members of the same subfamily had similar gene structures, and there were great differences among different subfamilies. These predicted cis-acting elements were related to plant hormones, stress resistance, and plant growth and development. The expression of BjuMAPK02, BjuMAPK15, BjuMAPK17, and BjuMAPK19 were down-regulated or up-regulated in response to P. brassicae infection. The above results lay a theoretical foundation for further studying the functions of BjuMAPK genes in B. juncea in response to the biotic stress caused by clubroot disease.

Objective To establish an animal model of osteoporosis combined with liver cirrhosis and conduct preliminary investigation into the effect of liver cirrhosis on bone loss in mice and the underlying mechanisms.Methods The experimental animals were 25 6-week-old female C57BL/6 mice with a body weight of approximately 20-22 g.A comorbidity model of liver cirrhosis and osteoporosis was established in the mice by ovariectomy combined with carbon tetrachloride(CCl4)induction.The mice were randomly assigned to 4 groups(n=5 in each group),including a control group,a liver cirrhosis group,an osteoporosis group,and a cirrhosis and osteoporosis comorbidity group.Pathological changes in the liver were observed via HE staining,Sirius Red staining,and serum liver function indicators.Bone mass and morphological changes were assessed using micro-CT and HE staining.ELISA,Western blot,and immunohistochemistry were performed to assess the expression of insulin-like growth factor-1(IGF-1)in serum and liver tissues.An additional IGF-1 intervention group was established to investigate the potential role of IGF-1 in the comorbidity of liver cirrhosis and osteoporosis,and changes in bone mass and morphology were analyzed via micro-CT and HE staining.Results Compared with the control and osteoporosis groups,the liver cirrhosis and cirrhosis-osteoporosis comorbidity groups exhibited significant inflammatory cell infiltration and collagen fiber deposition in liver tissues,along with markedly increased serum levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),and total bilirubin(TBIL)(P＜0.05).According to the Micro-CT and HE staining results,the cirrhosis-osteoporosis comorbidity group showed reduced bone mass and decreased trabecular numbers in the distal femur compared to those in the osteoporosis group,with the differences being statistically significant(P＜0.05).ELISA,Western blot,and immunohistochemistry demonstrated significantly reduced expression of IGF-1 in the liver and serum of the cirrhosis-osteoporosis comorbidity group(P＜0.05).Notably,exogenous IGF-1 treatment restored bone mass in mice with liver cirrhosis combined with osteoporosis(P＜0.05).Conclusion Through ovariectomy combined with CCl4 induction,a mouse model of liver cirrhosis combined with osteoporosis was successfully established.IGF-1 may serve as a potential molecular mechanism and therapeutic target mediating the liver cirrhosis-osteoporosis comorbidity.

Objective:To systematically review the factors related to the aggressive behavior of hospitalized patients with schizophrenia in China.Methods:CNKI,Wanfang,VIP,China Biomedical Literature Database,PubMed,Cochrane Library,and Embase databases were searched to collect case-control studies on factors related to aggression in hospitalized patients with schizophrenia in China from its inception to June 2023.Analysis was per-formed using ReviewManager 5.3 to calculate pooled OR(95％CI)values.Results:Thirty-three studies were in-cluded.Medical staff coercive measures(OR=3.86,95％CI:2.75-5.43),unemployment(OR=1.44,95％CI:1.14-1.81),positive family history(OR=2.97,95％CI:2.29-3.87),poor medication compliance(OR=4.37,95％CI:3.36-5.69),young age(OR=3.13,95％CI:2.66-3.69),involuntary hospitalization(OR=3.34,95％CI:2.81-3.97),depression(OR=2.11,95％CI:1.68-2.66),emotional abuse(OR=1.13,95％CI:1.04-1.23),male(OR=2.70,95％CI:2.20-3.31),delusions(OR=2.14,95％CI:1.69-2.71),auditory hallucina-tions(OR=2.23,95％CI:1.70-2.94),and major life events(OR=3.21,95％CI:1.90-5.42)and previous history of aggressive behavior(OR=2.20,95％CI:2.06-2.34)were risk factors associated with aggressive be-havior in Chinese patients with schizophrenia,and social support(OR=0.46,95％CI:0.31-0.67)was a protec-tive factor.Conclusion:There are various factors related to aggressive behavior in hospitalized Chinese patients with schizophrenia,and medical staff should identify high-risk groups early according to the relevant factors,and effec-tively intervene in controllable factors to reduce the occurrence of aggressive behavior.

Objective:Pediatric chronic sinusitis （CRS） is a common disease within the field of otolaryngology-head and neck surgery. Due to the immaturity of sinus development and immune competence in children, its etiology and pathophysiology are complex, and its clinical features and outcomes differ significantly from those in adult patients. Currently, there are issues in the diagnosis and treatment of pediatric CRS, particularly in areas such as antibiotic use and surgical interventions, owing to a lack of sufficient attention. In recognition of this, the Chinese Rhinopathy Research Cooperation Group developed this expert consensus based on a systematic review of the latest literatures from both domestic and international sources, with reference to the latest evidence-based medical evidence worldwide, and in combination with their own clinical experience. The consensus covers various aspects including epidemiology, predisposing factors, pathophysiology, diagnosis and differential diagnosis, as well as treatment strategies such as medical therapy and surgical intervention. It aims to standardize the clinical diagnosis and treatment of pediatric CRS, improve clinical efficacy and patient satisfaction, reduce clinical expenditures, and decrease the occurrence of adverse reactions.

The WUSCHEL related-homeobox (WOX) family is one of the plant-specific transcription factor families, playing important roles in plant growth and development. In this study, 51 WOX gene family members were identified from the genome data of Brassica juncea by searching and screening with HUMMER, Smart and other software. Their protein molecular weight, amino acids numbers, and isoelectric point were analyzed by using Expasy online software. Furthermore, bioinformatics software was used to systematically analyze the evolutionary relationship, conservative region, and gene structure of the WOX gene family. The mustard WOX gene family was divided into three subfamilies: ancient clade, intermediate clade, and WUS clade/modern clade. Structural analysis showed that the type, organization form and gene structure of the conservative domain of WOX transcription factor family members in the same subfamily were highly consistent, while there was a certain diversity among different subfamilies. 51 WOX genes are distributed unevenly on 18 chromosomes of mustard. Most of the promoters of these genes contain cis acting elements related to light, hormone and abiotic stress. Using transcriptome data and real-time fluorescence quantitative PCR (qRT-PCR) analysis, it was found that the expression of mustard WOX gene was spatio-temporal specific, among which BjuWOX25, BjuWOX33, and BjuWOX49 might play an important role in the development of silique, and BjuWOX10, BjuWOX32, and BjuWOX11, BjuWOX23 respectively might play an important role in the response to drought and high temperature stresses. The above results may facilitate the functional study of mustard WOX gene family.

Three-amino acid loop extension (TALE) transcription factors play important roles in plant growth and cell differentiation. There are plenty of studies on TALE transcription factors in several model plants, but not in radish (Raphanus sativas). A genome-wide bioinformatics analysis identified 33 TALE family genes in the Xiang-Ya-Bai (XYB) radish, These genes, are distributed on nine chromosomes and all contain 4-6 exons. The 33 TALE genes in radish showed a co-linearity relationship with the 17 homologous genes in Arabidopsis thaliana. Moreover, a large number of stress response cis-elements were found in the promoter regions of these genes. Expression analysis showed that four genes in the BELL subfamily were highly expressed in roots, and two genes in the KNOX subfamily were highly expressed in shoots of bolting plants and callus. All radish TALE genes contain sequences encoding the conserved HOX domain, except for the gene RSA10037940, which is homologous to Arabidopsis KNATM. The deduced 3D structures of the TALE proteins irrespective of subtypes are highly similar. All the encoded proteins were weakly acidic and hydrophilic. The radish TALE gene family is relatively evolutionarily conserved, which was consistent with results from Arabidopsis, but quite different from that of rice. This study provides important clues for studying the biological functions of TALE transcription factors in radish.

Objective: To explore the mediating effect of sensation seeking and the moderating effect of parenting style at cumulative ecological risk on psychosexual health in left behind adolescents. Methods: Using convenience cluster sampling, 509 left behind adolescents in 12 middle and primary schools were selected from May to July 2020. Cumulative ecological risk, psychosexual health, sensation seeking and parenting style were evaluated at baseline (T1) and 1 year follow up (T2). Results: T1 accumulative ecological risk predicted T2 psychosexual health after sensation seeking at T1 was controlled ( β=0.37, P <0.01). T1 sensation seeking predicted T2 psychosexual health after controlled for psychosexual health at T1 ( β=-0.26, P <0.01), sensation seeking played a mediating role, indirect effect accounted for 35.85% of the total effect; T1 cumulative ecological risk ×T2 parenting style had predictive effects on T2 sensation seeking and psychosexual health ( β=0.17, -0.24, P <0.01). Conclusion The cumulative ecological risk influences psychosexual health through sensation seeking, parenting style moderates the associations between cumulative ecological risk, sensation seeking and psychosexual health. Left behind teenagers with high cumulative ecological risk can cultivate good sexual psychological level by reducing high seeking traits and optimizing parental rearing styles.

Objective:To systematically evaluate the clinical effect and safety of bevacizumab combined with FOLFOX regimen in patients with advanced colorectal cancer.Methods:An electronic search of Pubmed, Embase, CNKI and other Chinese and English databases were retried from their inception to December 2018 to identify relevant literatures, by taking "Bevacizumab, FOLFOX, Advanced Colorectal Cancer, Randomized Controlled Trial" as the keywords for retrieval. Patients were divided into a combination group (bevacizumab combined with FOLFOX program) and a control group (using FOLFOX program alone) according to the treatment method, using Revman 5.3 software for meta-analysis.Results:A total of 11 articles, involving 3178 patients, were included with 1599 in the combination group and 1579 in the control group. The objective group response rate ( OR=3.15, 95% CI: 2.25 ~ 4.40, Z=6.71, P<0.000 01) and disease control rate ( OR=2.73, 95% CI: 1.91 ~ 3.90, Z=5.49, P<0.000 1) in combination group were higher than those in the control group. In terms of adverse reactions, the incidence of gastrointestinal reactions in the combination group was higher than that in the control group ( OR=1.29, 95% CI: 1.07~1.55, Z=2.64, P=0.008 ), There was no significant difference in the incidence of liver injury, leukopenia, hypertension, and neurotoxicity between the two groups. Conclusion:Bevacizumab combined with FOLFOX regimen is more effective than FOLFOX regimen for patients with advanced colorectal cancer, but it will increase the risk of gastrointestinal reactions.

Objective:To evaluate the efficacy and safety of using platelet-rich plasma (PRP) eyedrops for the treatment of moderate to severe dry eye disease (DED).Methods:A total of 395 patients (790 eyes) with moderate to severe DED diagnosed and treated in the Armed Police Liaoning Corps Hospital and the PLA 967 Hospital from March 2018 to October 2019 were collected. Random number table method was used to divide into autologous PRP treatment group (196 cases, 392 eyes) treated with autologous PRP and control group (199 cases, 398 eyes) treated with artificial tears. The changes of subjective symptoms of DED, Schirmer test (ST), corneal fluorescein staining (CFS) and Ocular Surface Disease Index (OSDI) before and after treatment were observed in both groups.Results:After 1 course of treatment, the ST values of both groups increased, which was statistically significant compared with before treatment ( P<0.05). After treatment, the OSDI and CFS scores of the two groups were reduced. The difference in OSDI and CFS scores of the PRP treatment group before and after treatment was statistically significant ( P<0.05), and there was no statistically significant difference in the control group before and after treatment ( P>0.05). After treatment, the OSDI and CFS scores of the PRP treatment group were lower than those of the control group [(16.8 ± 18.7) scores vs. (43.2 ± 14.5) scores, (0.21 ± 0.53) scores vs. (1.62 ± 0.69) scores], the differences were statistically significant ( P<0.05). After one course of treatment, the total effective rate of the autologous PRP treatment group was higher than that of the control group [80.1% (157/196) vs. 51.76% (103/196)], the difference was statistically significant ( P<0.05). Conclusions:Autologous PRP can treat patients with moderate-to-severe autologous PRP treatment group, which can greatly improve patients' eye discomfort and other symptoms.

Poor experience of teacher-student interaction and low user loyalty exist in MOOC (massive open online courses).Therefore,the campus open online courses (COOC),a network teaching platform,was developed to integrate traditional classroom teaching and network teaching and to build an online-offline curriculum system according to professional training scheme of school.The online-offline teaching design and learning evaluation in COOC platform was also developed.The running data of COOC platform showed that the online-offline learning evaluation model has guiding impact on students' learning attitude because it can record the students' learning process and learning effect,which can enhance students' active participation in self-directed learning.The learning evaluation model in COOC is objective and scientific,which is helpful to improve the quality of teaching and learning.
