BackgroundSleep disorder in the first trimester is a fairly common health problem, and previous studies have mainly reflected the overall sleep quality through scale assessments, which may not accurately capture the differences among various subtypes. ObjectiveTo explore the latent profiles of sleep quality in first-trimester pregnant women and identify the physiological, psychological and social factors, in order to provide practical references for the development of personalized interventions for sleep disorders in first-trimester pregnant women. MethodsA total of 1 066 first-trimester pregnant women who visited the obstetric outpatient clinic of a tertiary A hospital in Shenzhen from October 2021 to October 2022 were investigated using the general information questionnaire, Pittsburgh Sleep Quality Index (PSQI), Edinburgh Postnatal Depression Scale (EPDS), Chinese version of short International Physical Activity Questionnaire (IPAQ-S-C) and Social Capital Assessment Tool in Pregnancy for Maternal Health (SCAT-MH). Then the sleep profiles were identified through latent profile analysis, and the robust mixture regression model was employed to determine the influencing factors of sleep profiles. ResultsA 3-profile solution showed the best fit: 732 cases (68.67%) of good sleep quality group, 87 cases (8.16%) of low sleep efficiency group, and 247 cases (23.17%) of daytime dysfunction group. In comparison with subjects in good sleep quality group, first-trimester pregnant women in low sleep efficiency group were at a younger age (OR=0.951, 95% CI: 0.922~0.980), held a Bachelor's degree or above (OR=1.869, 95% CI: 1.260~2.773) and exhibited lower levels of social capital (OR=0.962, 95% CI: 0.951~0.973), while those in daytime dysfunction group were at an older age (OR=1.072, 95% CI: 1.027~1.120) and had higher levels of depression (OR=1.166, 95% CI: 1.115~1.218). Pregnant women who were workers (OR=0.507, 95% CI: 0.293~0.876) were less likely to report daytime dysfunction. ConclusionThree latent profiles with significant heterogeneity are derived from the sleep quality of first-trimester pregnant women, and levels of depression and social capital are the main influencing factors of sleep quality.

To reduce the dependency on high-carbon-load chromatographic columns,a new method has been established for the determination of the content of docusate sodium using ion-pair high-performance liquid chromatography (IP-HPLC). Tetrapropylammonium chloride was used as the ion-pair reagent with a mobile phase, composition of acetonitrile:10 mmol/L tetrapropylammonium chloride solution = 66∶34, adjusting pH to 6.5 with 0.1% phosphoric acid solution,flow rate of 1.5 mL/min, detection wavelength of 214 nm,column temperature of 35 °C, and an injection volume of 25 μL,and quantified by an external standard method. The main peak of docusate sodium exhibited a tailing factor of 1.34. The method showed good linearity within the range of 0.02 mg/mL to 0.40 mg/mL, with a correlation coefficient (r) of 0.999 9. It also demonstrated good repeatability, with recovery ranging from 97.0% to 98.2% (n=6). The quantification limit was 3.31 μg/mL, and the detection limit was 2.76 μg/mL.In summary,the new method shows good durability, a wide linear range, and high sensitivity, it is suitable for the determination of docusate sodium.

Objective:
To analyze the characteristics of first-visit cases of herpes zoster in Zhoushan City, Zhejiang Province from 2021 to 2023, so as to provide the reference for improving herpes zoster prevention and control measures.
Methods:
Data on the incidence and vaccination of first-visit herpes zoster cases at all levels of public medical institutions in Zhoushan City from 2021 to 2023 were collected through the Zhoushan Comprehensive Health Information Platform and Zhoushan Immunization Program Information Management System. The incidence and outpatient proportion were calculated. The population distribution, seasonal distribution, and clinical consultation status of first-visit herpes zoster cases were described.
Results:
From 2021 to 2023, a total of 15 156 first-visit herpes zoster cases were reported in Zhoushan City, with an average annual incidence of 5.36‰. The incidences for each year were 5.78‰, 5.29‰ and 5.02‰, respectively, and the outpatient proportions were 0.15%, 0.14% and 0.11%, respectively, showed decreasing trends (both P<0.05). The number of doses of recombinant herpes zoster vaccine or live attenuated herpes zoster vaccine administered were 130, 312, and 633, respectively. The main consultation department was dermatology, with 11 004 cases (72.60%). The primary clinical diagnosis was visceral herpes zoster, with 5 901 cases (38.94%). A total of 1 936 cases (12.77%) had at least one underlying medical condition. The mean age of onset was (56.08±16.23) years, and the incidence showed an upward trend with increasing age (P<0.05). There were 7 386 male cases and 7 770 female cases, with a male-to-female ratio of 0.95∶1. The incidence among males aged ≥50 years was lower than that among females (6.53‰ vs. 8.69‰, P<0.05). The onset of the disease exhibited a significant seasonal pattern, with a peak period from June 21st to August 21st, covering 75% of the cases
Conclusions
From 2021 to 2023, the incidence and outpatient proportion of herpes zoster in Zhoushan City decreased. Summer was the peak season for onset, and women and the elderly were the key populations. It is necessary to strengthen the collaborative diagnostic and treatment capabilities of key departments such as dermatology and enhance the enthusiasm for vaccination among key populations.

INTRODUCTION:
We aimed to understand the awareness and attitudes of elderly Southeast Asians towards telehealth services during the coronavirus disease 2019 (COVID-19) pandemic in this study.
METHODS:
In this qualitative study, 78 individuals from Singapore (51.3% female, mean age 73.0 ± 7.6 years) were interviewed via telephone between 13 May 2020 and 9 June 2020 during Singapore's first COVID-19 'circuit breaker'. Participants were asked to describe their understanding of telehealth, their experience of and willingness to utilise these services, and the barriers and facilitators underlying their decision. Transcripts were analysed using thematic analysis, guided by the United Theory of Acceptance Use of Technology framework.
RESULTS:
Of the 78 participants, 24 (30.8%) were able to describe the range of telehealth services available and 15 (19.2%) had previously utilised these services. Conversely, 14 (17.9%) participants thought that telehealth comprised solely home medication delivery and 50 (51.3%) participants did not know about telehealth. Despite the advantages offered by telehealth services, participants preferred in-person consultations due to a perceived lack of human interaction and accuracy of diagnoses, poor digital literacy and a lack of access to telehealth-capable devices.
CONCLUSION
Our results showed poor overall awareness of the range of telehealth services available among elderly Asian individuals, with many harbouring erroneous views regarding their use. These data suggest that public health education campaigns are needed to improve awareness of and correct negative perceptions towards telehealth services in elderly Asians.

INTRODUCTION:
Acute severe ulcerative colitis (ASUC) is a significant cause of disease morbidity. One-third of patients with ASUC are steroid refractory. Rescue therapy may not successfully induce remission, necessitating colectomy. We aimed to identify predictors of rescue therapy and colectomy in ASUC assessed within 24 h of admission for early risk stratification.
METHODS:
We conducted a retrospective cohort study of 58 admissions for ASUC among 47 patients from August 2002 to January 2022. Serum biomarkers assessed were measured on admission. Primary outcomes were the need for rescue therapy during the same admission and colectomy within 1 year of admission.
RESULTS:
Rescue therapy (all with infliximab) was given in 20 (34.5%) of the admissions. Colectomy was done within 1 year for nine (15.5%) of the admissions. An elevated C-reactive protein (CRP) of >30 mg/L (relative risk [RR] 1.63), a CRP-albumin ratio of >0.85 (RR 1.63), and a composite factor of both CRP > 30 mg/L and age ≥60 years (RR 2.37) were significantly associated with the need for rescue therapy. Hypoalbuminaemia ≤ 25 g/L (RR 4.35) and the use of biologics at presentation (RR 1.54) were significantly associated with colectomy within 1 year of admission, while a CRP of ≥ 80 mg/L was a significant protective factor (RR 0.70).
CONCLUSION
Patients with ASUC who have elevated CRP or CRP-albumin ratio on admission should be considered at risk for steroid-refractory disease. Those with hypoalbuminaemia on admission and using biologics at presentation are more likely to require colectomy in the first year after admission for ASUC.

Tujia ethnic group medicine Xuetong is derived from Kadsura heteroclita, the stem of which has the medicinal value for anti-rheumatoid arthritis, liver protection, anti-tumor, anti-oxidation effects, and has been widely used in Hunan and Guangdong in China. The selection of reliable and stable reference genes is the basis for subsequent molecular research on K. heteroclita. In this study, GAPDH, TUA, Actin, UBQ, EF-1α, 18S-rRNA, CYP, UBC, TUB, H2A, and RPL were selected as candidate reference genes in Kadsura heteroclita. The gene expression levels of the 11 candidate reference genes of K. heteroclita in its 6 different parts(stem-inside of the cambium, stem-outside of the cambium, fruit, flower, root, and leaf) and under different intervention conditions [drought stress, salt stress, and methyl jasmonate(MeJA) treatment] were detected by quantitative real-time polymerase chain reaction(qRT-PCR). The expression stability of the 11 candidate reference genes was comprehensively analyzed and evaluated by geNorm, NormFinder, ΔCT algorithm, and RefFinder software. The results showed that the expression of UBC and RPL was relatively stable in 6 different parts, and UBC and GAPDH genes were relatively stable under different intervention conditions. To verify the reliability of reference genes for K. heteroclita, this study further examined the relative expression levels of KhFPS, KhIDI, KhCAS, KhSQE, KhSQS, KhSQS-2, KhHMGS, KhHMGR, KhMVD, KhMVK, KhDXR, KhDXS, KhPMVK, and KhGGPS in different parts and under different intervention conditions, which might relate to the synthesis of the main component(Xuetongsu) of K. heteroclita. The results showed that with UBC and RPL or UBC and GAPDH as the reference genes, the expression trends of these 14 genes were basically consistent in different parts or under different intervention conditions for K. heteroclita. In conclusion, UBC can be used as a reference gene of K. heteroclita for its different parts and different intervention conditions, which lays a foundation for further research on the biosynthetic pathway of main components in K. heteroclita.

This study aims to explore the synergistic effects of the main components in salvianolic acids for Injection(SAFI) on key pathological events in cerebral ischemia, elucidating the pharmacological characteristics of SAFI in neuroprotection. Two major pathological gene modules related to endothelial injury and neuroinflammation in cerebral ischemia were mined from single-cell data. According to the topological distance calculated in network medicine, potential synergistic component combinations of SAFI were screened out. The results showed that the combination of caffeic acid and salvianolic acid B scored the highest in addressing both endothelial injury and neuroinflammation, demonstrating potential synergistic effects. The cell experiments confirmed that the combination of these two components at a ratio of 1∶1 significantly protected brain microvascular endothelial cells(bEnd.3) from oxygen-glucose deprivation/reoxygenation(OGD/R)-induced reperfusion injury and effectively suppressed lipopolysaccharide(LPS)-induced neuroinflammatory responses in microglial cells(BV-2). This study provides a new method for uncovering synergistic effects among active components in traditional Chinese medicine(TCM) and offers novel insights into the multi-component, multi-target acting mechanisms of TCM.
