Objective:To investigate the effect of Chinese Herbal Anti-Alopecia and Hair Growth Solution(CHAaHGS)on the hair growth through in vitro experiments on the human dermal papilla cells(HDPCs),in vivo experiments in the C57BL/6 mice,and human efficacy tests,and to clarify its potential mechanism.Methods:The HDPCs were divided into control group,CHAaHGS group,and minoxidil group.MTT method was used to detect the proliferation activities of HDPCs in various groups;enzyme-linked immunosorbent assay(ELISA)method was used to detect the levels of vascular endothelial growth factor(VEGF),hepatocyte growth factor(HGF),insulin-like growth factor-1(IGF-1),and transforming growth factor β1(TGF-β1)in the supernatant of HDPCs in various groups;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of VEGF,HGF,IGF-1,TGF-β1,and alkaline phosphatase(ALP)mRNA in the HDPCs in various groups;Western blotting method was used to detect the expression levels of β-catenin,dishevelled segment polarity protein 1(DVL1),glycogen synthase kinase 3β(GSK-3β),phosphorylated GSK-3β(p-GSK-3β),and wingless-type MMTV integration site family member 3a(Wnt3a)proteins in the HDPCs in various groups.A total of 18 mice were randomly divided into control group,CHAaHGS group,and minoxidil group,with 6 mice in each group.The mouse hair loss model was established using hair removal cream,and corresponding drug treatments were administered immediately after hair removal.The lengths and weights of newly grown hair on day 21 of the mice in various groups were detected;HE staining was used to observe the morphology of hair follicles in the dorsal depilated skin areas of the mice in various groups on day 7;ELISA method was used to detect the levels of VEGF,HGF,IGF-1,and TGF-β1 in the skin tissue of dorsal depilated areas of the mice in various groups.Sixty subjects were randomly divided into control group and CHAaHGS group,with 30 subjects in each group.The numbers of hair loss and hair densities of the subjects in various groups were detected at weeks 0,4,8,and 12.Results:The MTT assay results showed that compared with control group,the proliferation activity of the cells in 50 mg·L-1CHAaHGS group was significantly increased(P＜0.01).The ELISA assay results showed that compared with control group,the levels of VEGF,HGF,and IGF-1 in the cell supernatant of HDPCs in CHAaHGS group were significantly increased(P＜0.05 or P＜0.01),and the TGF-β1 level was significantly decreased(P＜0.01).The RT-qPCR results showed that compared with control group,the expression levels of VEGF,HGF,IGF-1,and ALP mRNA in the cells in CHAaHGS group were significantly increased(P＜0.05 or P＜0.01),and the TGF-β1 mRNA expression level was significantly decreased(P＜0.01).The Western blotting results showed that compared with control group,the expression levels of β-catenin,DVL1,p-GSK-3βand Wnt3a proteins in the cells in CHAaHGS group were significantly increased(P＜0.05 or P＜0.01),and the GSK-3β protein expression level was significantly decreased(P＜0.05).In animal experiments,on day 21,compared with control group,the length of newly grown hair of the mice in CHAaHGS group was significantly increased(P＜0.05),and the hair weight was significantly increased(P＜0.01).On day 7,the HE staining results showed that compared with control group,the hair follicle spacing of the mice in CHAaHGS group was significantly decreased(P＜0.05),and the number of hair follicles was significantly increased(P＜0.01);the ELISA assay results showed that compared with control group,the levels of VEGF,HGF,and IGF-1 in skin tissue of dorsal depilated area of the mice in CHAaHGS group were significantly increased(P＜0.05 or P＜0.01),and the TGF-β1 level was significantly decreased(P＜0.05).In human efficacy test,compared with control group,the number of hair loss of the subjects in CHAaHGS group was significantly decreased at week 12(P＜0.01),and the local hair density was increased(P＜0.05).Conclusion:CHAaHGS promotes hair growth,and the mechanism may be related to its ability to increase the proliferation activity of HDPCs,induce the secretion of VEGF,HGF,and IGF-1,and activate the Wnt/β-catenin signaling pathway.

Objective:To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023.Methods:The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed.Results:A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M ( Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant ( P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age ( P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion:Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

The purpose of this paper is to review the research progress on the effects of obstructive sleep apnea （OSA） on memory consolidation， and to speculate on possible mechanisms underlying these effects， so as to inform the exploration of effective therapeutic measures for impaired memory consolidation. Previous studies have shown that mild OSA may impair different types of memory consolidation， and the impairments are closely related to certain indices of polysomnography （such as sleep microstructure， apnea hypopnea index， arousal index， etc）. Therefore， it is hypothesized that disruption of sleep architecture and damage to brain regions and neural pathways associated with sleep-dependent memory consolidation due to intermittent hypoxia may trigger a decline in memory consolidation. Meantime， long-term continuous positive airway pressure can alleviate the impairment of memory consolidation induced by OSA， but whether other interventions can mitigate the damage remains unclear.

Objective:To understand the current situation of smartphone addiction and mental health of medical freshmen, and conduct research on the relationship between smartphone addiction and mental health, so as to provide evidence for the prevention and intervention of smartphone addiction among medical freshmen.Methods:A stratified random sampling method was used to select 279 freshmen in the medical profession of Binzhou Medical University as the research objects, and the revised smartphone addiction scale (SAS-C) and mental health symptom self-rating checklist scale (SCL-90) were selected for testing. SPSS 19.0 was used for t test. Results:A percentage of 29.71 medical freshmen had smartphone addiction problems, which was generally above average. The SCL-90 total scores and the scores of somatization, interpersonal sensitivity, depression, anxiety, hostility, psychosis and other factors in the smartphone addiction group were significantly higher than those in non-smartphone addiction group. The total score of smartphone addiction in medical professional freshmen was significantly correlated with the total score of SCL-90. In addition to the interference factors of daily life, other factors had positive correlation with various factors of SCL-90. Interpersonal sensitivity and obsessive-compulsive symptoms had a significant predictive effect on smartphone addiction (β=0.24, 0.26, P < 0.01), which were important variables affecting mobile phone addiction of medical freshmen. Conclusion:Many medical freshmen have the problem of smartphone addiction, which may cause a series of psychological problems, especially obsessive-compulsive symptoms, interpersonal sensitivity, anxiety and psychosis.

Objective To understand the status quo of stressors and mental health of undergradu-ates of local medical colleges in internship and provide relevant countermeasures so as to provide scientific reference for psychological health counseling for them. Methods The stress source scale and mental health symptom self-rating scale for medical students in internship (SCL-90) coded by Chang Lirong et al was adopted to investigate. The questionnaire survey was conducted on the stress and mental health status of 390 interns in Binzhou Medical College, and 384 valid questionnaires were collected, with the effective rate of recovery as 98.46%. The questionnaire results were analyzed by sample t test, variance analysis and Pearson correlation analysis. Results A total of 24.1% of students in local medical schools were under moderate pressure (1.17±0.63). The highest pressure source was examination and employment (1.58±0.74), and the other followed were knowledge and skills (1.43 ±0.68), interpersonal relationships (1.11 ±0.54), patients (1.06±0.53), medical conditions (1.00±0.53) and work load (0.95±0.52) respectively. The scores of various stressors were significantly and positively correlated with most of the mental health factors. Conclusion The undergraduates of local medical colleges and universities are generally under stress in internship, which would affect their mental health. It is suggested that the interns should be guided from the aspects of employment, study and psychology so as to help them relieve their stress and develop good psychological qualities.

Objective:To investigate the effectiveness of immunoFISH technology in detecting tumor cells in cerebrospinal fluid (CSF) for adjuvant diagnosis of meningeal metastasis from lung cancer. Methods:Circulating tumor cells (CTCs) were detected by im-munoFISH technology in CSF samples from 16 patients with meningeal metastasis from lung cancer and 8 patients with non-tumorous brain diseases. Meningeal metastasis from lung cancer was diagnosed on the basis of neurological symptoms and confirmed by en-hanced magnetic resonance imaging and CSF cytological examination. Results:The number of CTCs was significantly greater in pa-tients with meningeal metastasis from lung cancer than in those with non-tumorous brain diseases (P<0.01). The critical point of the maximum correct diagnosis index (Youden index) was regarded as the judging criterion for the positive tumor cells in CSF based on the receiver operating characteristic curve. When one tumor cell existed in 7.5 mL of CSF, the area under the curve was 0.875, and the 95%confidence interval ranged from 0.705 to 1.000. The diagnostic sensitivity, specificity, effectiveness, positive predictive values, and neg-ative predictive values were 75.0%, 100.0%, 83.3%, 100.0%, and 66.7%, respectively. Conclusion:ImmunoFISH technology provides great significance in detecting CTCs in CSF to diagnose meningeal metastasis from lung cancer.
