Review
The tyrosinase enzyme, which is widely found in microorganisms, animals and plants, has a significant position in melanogenesis, plays an important role in undesirable browning of fruits and vegetables, antibiotic resistance, skin pigment formation, sclerotization of cuticle, neurodegeneration, etc. Therefore, with the wide potential application fields of tyrosinase in food, agriculture, cosmetics and pharmaceutical industries, which has become the target enzyme for the development of therapeutic agents such as antibrowning, anticancer, antibacterial, skin whitening, insecticides, etc., a large number of synthetic tyrosinase inhibitors have been widely reported in recent years. The triazole ring, which has a broad spectrum of biological action, is of increasing interest in the synthesis of new tyrosinase inhibitors. In this review, tyrosinase inhibition effects, structure-activity relationships, enzyme inhibition kinetics and mechanisms of action of 1,2,3- or 1,2,4-triazole derivatives were investigated. The data gathered is anticipated to supply rational guidance and an influential strategy for the development of novel, potent and safe tyrosinase inhibitors for better practical application in the future.

Review
Parkinson's disease (PD) often presents with autonomic dysregulation, leading to blood pressure irregularities such as neurogenic orthostatic hypotension (nOH), neurogenic supine hypertension (nSH), and postprandial hypotension (PPH). Unfortunately, these conditions remain prevalent and receive insufficient attention in scientific discourse. They not only cause complications like syncope, falls, and fractures but also result in long-term damage to vital organs, diminishing patients' quality of life. Early implementation of appropriate non-pharmacologic management is crucial to prevent severe adverse events later on. This review focuses on the types, clinical characteristics, mechanisms, and common non-pharmacologic management measures for PD complicated by abnormal blood pressure. By promoting early diagnosis, recognizing symptoms of abnormal blood pressure, and employing non-pharmacologic interventions such as health education, dietary adjustments, exercise, and Chinese medicine techniques, we aim to improve patients' symptoms and quality of life while providing practical guidance for managing PD-related blood pressure abnormalities.

Since March 2020, the pandemic caused by SARS-CoV-2 has affected nearly all aspects of daily life. In this study, we investigated the age-stratified prevalence and genotype distribution of human papillomavirus (HPV) among females in Shandong province (eastern China) and aimed to provide guidance on HPV-based cervical cancer screening and vaccination. The distribution of HPV genotypes was analyzed using PCR-Reverse Dot Hybridization. The overall infection rate of HPV was 16.4%, which was dominated by high-risk genotypes. The most prevalent genotype was HPV16 (2.9%), followed by HPV52 (2.3%), HPV53 (1.8%), HPV58 (1.5%), and HPV51 (1.3%). Among the positive cases with HPV infection, single-genotype infection was significantly higher than that of multi-genotype infection. In subgroup analyses by age (≤25, 26-35, 36-45, 46-55, >55), HPV16, 52, and 53 were consistently the three most common hrHPV genotypes in all age groups. The infection rate of multi-genotypes in the ≤25 and >55 age groups was significantly higher than that in other age groups. A bimodal distribution of HPV infection rate was observed in different age groups. Among lrHPV genotypes, HPV6, HPV11, and HPV81 were the three most common types in the ≤25 age group, while in other age groups, HPV81, HPV42, and HPV43 are the three most common lrHPV genotypes. This study provides basic information on the distribution and genotypes of HPV in the female population in eastern China, which could improve the application of HPV diagnostic probes and vaccines.

BACKGROUND
The vocational guidance process in educational institutions faces important challenges in managing trials and errors in diagnoses. Technological tools are identified as an effective solution to address these problems. This research seeks to improve career guidance in educational institutions through the implementation of an expert system. The main objective is to reduce test processing time and achieve greater efficiency in students' self-knowledge regarding their interests, based on the personalities of the Holland Test.
METHODS
The development of the expert system followed a six-model approach. First, an organisational model was created to assess the scope and feasibility of the project. Next, a task and agent model was developed to investigate the impact and look for improvements. A knowledge model was then developed to analyse the relevant knowledge bases. A communication model was also developed to evaluate the communication interface of the system. Next, a design model was created to provide guidelines for the implementation of the system. Finally, the implementation of the knowledge system was carried out to ensure its correct functioning.
RESULTS
The implementation of the expert system has shown significant improvements in the vocational guidance process. It was possible to reduce the time needed to apply the test, thus optimising the psychologist's time and allowing a greater capacity for analysis. In addition, an improvement in the effectiveness of the students' self-knowledge in relation to their vocational interests based on the personalities of the Holland Test was observed.
CONCLUSIONS
This study contributes to career guidance in educational institutions by introducing an innovative expert system. This technological solution optimizes the career guidance process, benefiting psychologists administering tests and students seeking self-knowledge about their career interests.

Review
INTRODUCTION
Return-to-work is a key rehabilitation goal for many working aged stroke survivors, promoting an overall improvement of quality of life, social integration, and emotional wellbeing. Conversely, the failure to return-to-work contributes to a loss of identity, lowered self-esteem, social isolation, poorer quality of life and health outcomes. Return-to-work programmes have largely focused on physical and vocational rehabilitation, while neglecting to include mood and fatigue management. This is despite the knowledge that stroke results in changes in physical, cognitive, and emotional functioning, which all impact one's ability to return to work. The purpose of this systematic review is to conduct a comprehensive and up-to-date search of randomised controlled trials (RCTs) of return-to-work programmes after stroke. The focus is especially on examining components of mood and fatigue if they were included, and to also report on the screening tools used to measure mood and fatigue.
METHOD
Searches were performed using 7 electronic databases for RCTs published in English from inception to 4 January 2023. A narrative synthesis of intervention design and outcomes was provided.
RESULTS
The search yielded 5 RCTs that satisfied the selection criteria ( = 626). Three studies included components of mood and fatigue management in the intervention, of which 2 studies found a higher percentage of subjects in the intervention group returning to work compared to those in the control group. The remaining 2 studies which did not include components of mood and fatigue management did not find any significant differences in return-to-work rates between the intervention and control groups. Screening tools to assess mood or fatigue were included in 3 studies.
CONCLUSION
Overall, the findings demonstrated that mood and fatigue are poorly addressed in rehabilitation programmes aimed at improving return-to-work after stroke, despite being a significant predictor of return-to-work. There is limited and inconsistent use of mood and fatigue screening tools. The findings were generally able to provide guidance and recommendations in the development of a stroke rehabilitation programme for return-to-work, highlighting the need to include components addressing and measuring psychological support and fatigue management.

Allergic disease management for adolescents and young adults requires consideration of unique psychosocial challenges and opportunities. Erik Erikson's model for the Stages of Psychosocial Development is a useful lens through which we can understand adolescent and young adult experiences with allergic and immunologic disease, particularly with regard to identity and relationship development. It is important to provide anticipatory guidance for patients who are transitioning environments (eg, home to college), with attention to the anxiety-provoking demands for increased responsibility on top of new stressors such as academic and vocational demands. It is critical that health care professionals use an empathetic, shared decision-making approach regarding the emotional impact of allergy on a patient's social engagement. A patient's ability to develop positive lifelong habits is also shaped by their environment's "culture of wellness," and clinicians can encourage habits to promote healthy choices and effective disease management. Social media provides opportunities and challenges as a conduit for both social connection and possible misinformation. Overall, allergic disease management in adolescents and young adults is a "high-risk, high-reward" period of time-and with awareness, anticipation, and proactive action, health care professionals can better serve patients by leveraging this transitional period to promote positive approaches to management of allergies and asthma, trusting relationships, and personal responsibility.

BACKGROUND
Depression affects the development of adolescents and makes it difficult for them to adapt to future life. The purpose of this study was to elucidate the population characteristics of adolescent depression.
METHODS
This study measured depression based on the Patient Health Questionnaire-9 items and sociodemographic questionnaire. A total of 8,235 valid questionnaires were collected from six schools in Haikou and Qionghai, Hainan Province, covering the ages of 13 to 18. The questionnaires included high schools with multiple levels, including general high schools, key high schools, and vocational high schools. Latent category analysis (LCA) was used to identify potential categories of depressive symptoms among adolescents. Latent Class Analysis (LCA) was used for determining depressive symptom latent categories and their proportional distribution among adolescents.
RESULTS
LCA analysis divided the data into 3 categories, namely no depression, low depression, and high depression groups. The percentage of the high depression group was 10.1%, and that of the low depression group was 48.4%. The Jorden index was greatest for a PHQ-9 score of 14.5. The 1 grade of junior middle school students entered the high and low depression groups 1.72 and 1.33 times more often than seniors. The number of the 1 grade of high school students included in the high and low depression groups was 1.55 and 1.42 times of the 3 grade of high school students group. The detection rate of the high depression group of vocational school adolescents was 13.5%, which was significantly higher than that of key high schools (9.6%) and general high schools (9.0%).
CONCLUSION
This study found that 1 grade of junior middle school students and the 1 grade of high school students were more likely to fall into depressive conditions. Moreover, Adolescent girls require more attention than boys. Vocational school students need more psychological guidance.

Review
Research consistently documents the poor postsecondary outcomes of autistic individuals. It is important to identify supports that help autistic individuals get and keep jobs to improve postsecondary outcomes. Autism diagnosis disclosure at work may serve as a support (e.g., receiving accommodations) or as a barrier (e.g., discrimination) to getting and keeping employment, but little is known about the lived experiences of autistic individuals on diagnosis disclosure at work. To better understand why individuals on the spectrum choose to pursue disclosure or choose not to disclose at work, how they disclose, and the consequences of that disclosure, a state-of-the-art literature review was conducted. Ten studies met the final inclusion criteria and were synthesized to provide guidance to autistic individuals, families, and professionals who support their transition to employment. Findings from the review indicate that diagnosis disclosure is a highly complex decision. Across reviewed studies, participants chose to pursue disclosure for specific reasons, including access to accommodations or support, increase understanding, and advocate for self or others. Autistic individuals participating across reviewed studies shared they chose not to disclose primarily due to fears of discrimination and experience of stigma. Both the hopes (access to accommodations and supports) and fears (bullying and discrimination) were validated in the experienced consequences of disclosure. More research is needed on the contextual experiences of how individuals on the spectrum disclose their diagnosis at work.

Initial vocational training (VT) in high school consists of short-term programs leading to employment in a skilled trade. To better align training with employment opportunities and to encourage students to stay in the programs until they graduate, most programs include traineeship. Since traineeships involve acquiring skills directly on the job, they require greater involvement of supervisors to guide the trainees. Given the importance of on-the-job guidance in achieving traineeship objectives, this study examines the potential influence of three dimensions of guidance provided by traineeship supervisors -planning, support, and training- on students' job perception (i.e., occupational image) and traineeship satisfaction. Overall, the results provide mixed results, partially supporting the mediation hypothesis suggested by the results of previous studies. Indeed, the results reveal that the quality of the training offered by the supervisor affects subsequent students' satisfaction with traineeship experience. Training has an indirect effect on satisfaction via the occupational image held by students. However, the expected indirect links between the other two dimensions of supervisor guidance -degree of planning and support perceived by the student- and the students' image of their chosen occupation could not be confirmed. The results support the importance of providing quality on-the-job training to students during their studies.
