Objective To systematically review international research on health communication, and to provide valuable insights and reference for China's health communication research and practice. Methods This study included 693 articles published from January 2023 to April 2024 in two authoritative academic journals in the field of health communication, “Health Communication” and the “Journal of Health Communication”. A systematic review was conducted on the themes, theoretical foundations, research methods, and populations of international health communication research. Results The findings in this study revealed that international health communication research topics were diverse, with hotspots including social media, health information behavior, health misinformation, stigmatization, trust, and risk perception. The results showed that 34% of the articles were based on theoretical foundations, and 93.3% employed research methods, focusing on adolescents, parents, women, and other key populations. Conclusion Domestic health communication research can expand its perspective from “information transmission” to “social interaction”, innovate theories and methods from “single paradigm" to “multi-integration” and shift focus from a “mass perspective” to “targeted care” for the health of all populations. Domestic health communication practice can delve into the localization of social media health communication practices, the comprehensive management of health misinformation, and the critical application of new technologies.

Background: Sex-based differences often influence the therapeutic efficacy and safety of medications. Semen Cuscutae is a traditional tonic botanical drug with sex-specific characteristics, traditionally indicated for conditions such as impotence (exclusive to males) and restless fetus (exclusive to pregnant females). However, most existing studies have focused on a single sex. Objective: To evaluate the sex-specific biological effects of Semen Cuscutae in rats and explore its molecular mechanisms, with the aim of uncovering its pharmacological characteristics through a multiomics approach. Methods: A traditional aqueous extract of Semen Cuscutae (SCA) was used as the experimental material. Forty adult Sprague-Dawley rats (equal numbers of males and females) were randomly divided into 4 groups: male control, male SCA treatment (240 mg/kg), female control, and female SCA treatment (240 mg/kg), with 10 rats in each group. The biological effects were comprehensively evaluated using a combination of open field test, biochemical analyses, proteomics, and gut microbiota profiling. Results: As a tonic botanical drug, SCA appeared to directly affect the mental and behavioral state of rats. It significantly altered the time spent by rats in the center area during the open field test, showing a sex-dependent reversal of behaviors. Proteomic analysis of brain tissue identified 624 differentially expressed proteins across the groups, with 10 key differentially expressed proteins related to sex differences, including fibroblast growth factor receptor 3, transcription elongation factor A protein-like 1, 40S ribosomal protein S25, neural cell adhesion molecule, and anion exchange protein 2 (SLC4A2). Enrichment analysis revealed that in male rats, SCA upregulated proteins involved in biological processes such as ribosome function and energy derivation, supporting protein synthesis and enhancing energy supply, showing an overall gain effect. In contrast, in female rats, SCA downregulated proteins associated with processes such as positive regulation of target of rapamycin (TOR) signaling and vesicle transport, suggesting suppression of neuronal signaling and material transport, indicative of a shift toward a more restrained physiological state. Furthermore, SCA reduced gut microbiota diversity in female rats but increased it in males, including the abundance of Akkermansia, which may serve as a crucial mediator. Conclusion: Overall, the biological effects of SCA differ significantly between male and female rats, with evidence suggesting greater health benefits in males. These findings help elucidate the scientific basis of its traditional applications and provide guidance for the precise application of SCA as a functional health food.

ObjectiveTo investigate whether intestinal deficiency of lanosterol synthase (LSS), a key enzyme in cholesterol synthesis, influences the progression of metabolic dysfunction-associated steatotic liver disease (MASLD) by regulating intestinal cholesterol absorption and immune response. MethodsLSS heterozygous knockout (LSS+/-) mice and wild-type (WT) controls were generated using CRISPR/Cas9 technology and fed either a high-fat diet (HFD) or regular chow (CHOW). The model was validated by genotyping. Hepatic steatosis was assessed by HE and oil red O staining. Immunohistochemistry was used to detect the localization and expression of NPC1L1 and CD36 proteins in the intestine. Western blot analysis was performed to measure JNK phosphorylation and TLR4 protein levels in intestinal tissues. Real-time quantitative polymerase chain reaction (qPCR) was employed to examine the mRNA expression of TLR4 and IL-6. ResultsLSS+/- mice were successfully validated by genotyping and reduced intestinal LSS protein expression. HE and oil red O staining of liver sections showed that, compared with WT mice fed a CHOW diet, WT mice fed a HFD exhibited a marked increase in hepatic lipid vacuoles. In contrast, compared with HFD-fed WT mice, HFD-fed LSS+/- mice displayed significantly attenuated hepatic lipid deposition and reduced serum ALT levels (P<0.05). Immunohistochemical analysis revealed that, compared with WT mice, the expression of the cholesterol absorption protein NPC1L1 in the intestinal villi of LSS+/- mice was downregulated under both CHOW and HFD conditions (PHFD<0.001). Conversely, the expression of the fatty acid transporter CD36 was upregulated in the intestines of LSS+/- mice (PCHOW<0.05, PHFD<0.01). Western blot analysis demonstrated that, compared with WT mice, TLR4 protein expression in the intestines of LSS+/- mice significantly increased under both CHOW and HFD conditions (both P<0.05). JNK phosphorylation level was significantly elevated in LSS+/- mice under CHOW condition (both P<0.05). Under HFD condition, total JNK protein expression increased, but its phosphorylation level showed no significant change. qPCR analysis showed that, compared with WT mice, the mRNA levels of TLR4 (PCHOW<0.01, PHFD<0.000 1) and IL-6 (PCHOW<0.001, PHFD<0.01) were significantly upregulated in the intestines of LSS+/-mice. ConclusionLSS deficiency counteracts hepatic lipid deposition by orchestrating a synergistic reprogramming involving restricted intestinal cholesterol absorption, enhanced fatty acid utilization, and activation of immune pathways, suggesting intestinal LSS as a potential therapeutic target of MASLD.

ObjectiveTo investigate the effect of hypoxia on pemetrexed (PE)-mediated apoptosis in non-small cell lung cancer cells. MethodsA549 cells were cultured under 21% O₂ (normoxia) or 1% O₂ (hypoxia), and treated with 8 μmol/L PE for 48 h. The cells were divided into normoxic control group, normoxic vehicle group, normoxic drug-treated group, hypoxic control group, hypoxic vehicle group and hypoxic drug-treated group. Trypan blue staining was used to observe cell death after PE intervention under normoxia and hypoxia. Flow cytometry was adopted to detect cell apoptosis rate. Wound healing assay was used to assess cell migration. Western blot was performed to detect the protein levels of MRP-1, Cleaved Caspase-3, E-Cadherin and N-Cadherin. ResultsTrypan blue staining results showed that the cell death rate was reduced in PE-treated cells under hypoxia compared with the normoxic PE group (P<0.001). Flow cytometry results indicated that PE induced cell apoptosis under both normoxic and hypoxic conditions.However, the apoptosis rate of the normoxic PE group was significantly higher than that of the hypoxic PE group (P<0.000 1). Wound healing assay showed that the migration distance of A549 cells decreased after PE treatment for 24 h and 48 h under normoxia and hypoxia when compared with the control group (P<0.05), while no significant difference was found between the normoxic PE group and the hypoxic PE group. Western blot results revealed that MRP-1 expression was markedly higher in hypoxic PE-treated cells than in normoxic PE-treated cells (P<0.000 1). Compared with the control group, Cleaved Caspase-3 expression was upregulated in A549 cells following PE intervention under normoxia (P<0.05), whereas no obvious alteration in Cleaved Caspase-3 expression was detected in hypoxic PE-treated cells. Under both normoxic and hypoxic conditions, PE treatment downregulated the expression of E-Cadherin (P<0.000 1,P<0.001) and N-Cadherin (P<0.05,P<0.000 1). In addition, the expression levels of E-Cadherin and N-Cadherin in the hypoxic PE group were significantly lower than those in the normoxic PE group (all P<0.000 1). ConclusionHypoxia significantly attenuates the pro-apoptotic effect of PE on A549 cells and blocks Cleaved Caspase-3 activation. This mechanism may be related to hypoxia-induced MRP-1 overexpression and reduced drug accumulation. Interfering with MRP-1 or restoring the activity of the apoptosis pathway may serve as a novel strategy to overcome hypoxia-induced drug resistance.

Objective:To explore the effect of long noncoding RNA ANK3DT (lncRNA ANK3DT) on DNA damage repair ability and radiosensitivity of cervical cancer HeLa cells.Methods:The effect of lncRNA ANK3DT on the repair efficiency of DNA double-strand breaks (DSBs) was analyzed by the pre-constructed quantitative assay system based on the CRISPR/Cas9 system targeting homologous recombination (HR) and non-homologous end-joining (NHEJ) repair. Clone formation assay, flow cytometry, and immunofluorescence were used to detect the effects of down-regulation of lncRNA ANK3DT on cellular radiosensitivity, apoptosis and G 2/M phase arrest, and DSB repair after X-ray irradiation. Western blot, qPCR, and dual fluorokinase reporter gene plasmid was used to detect the effects of lncRNA ANK3DT on the HR repair-related protein CtIP expression and transcriptional regulation. Results:Down-regulation of lncRNA ANK3DT significantly inhibited HR repair and had no effect on NHEJ repair. The expression of lncRNA ANK3DT was significantly increased in HeLa cells at 24, 48, 72 h after X-ray irradiation ( t=-23.39, -88.83, -52.42, P<0.05). Down-regulation of lncRNA ANK3DT inhibited X-ray-induced DSB repair and increased apoptosis levels ( t=-14.63, P <0.05), prolonged G 2/M phase block ( t=-19.50, P <0.05), increased the radiosensitivity of HeLa cells (radiosensitization ratio=1.21), inhibited the CtIP promoter activity and decreased its mRNA and protein expression. Conclusions:lncRNA ANK3DT affects HR repair by regulating CtIP transcription, and down-regulation of lncRNA ANK3DT increases the radiosensitivity of HeLa cells by inhibiting DSB repair after ionizing radiation.

Objective:To analyze the changing trend of cervical cancer epidemiological characteristics and disease burden in cancer registration areas of Guangxi Zhuang Autonomous Region (Guangxi) from 2010 to 2017, and to provide scientific basis for the development of cervical cancer prevention and control strategies in Guangxi.Methods:Using descriptive analysis method, based on the incidence and death data of cervical cancer in the tumor registration areas of Guangxi from 2010 to 2017, Crude morbidity, crude mortality, age-standardized morbidity and mortality (referred to as the winning rate), disability adjusted life years (DALYs) rate and the annual percentage change (APC) and average annual percentage change (AAPC) of the above indicators were calculated, and stratified analysis was conducted for urban and rural areas and different age groups.Results:From 2010 to 2017, the crude incidence rate of cervical cancer in Guangxi showed a significant upward trend, rising from 10.31/10 5 in 2010 to 19.94/10 5 in 2017, with an average annual growth rate of 7.9% ( P<0.05). However, after age standardization, the trend of the age-standardized incidence rate of cervical cancer was not statistically significant ( P>0.05). During the same period, the crude mortality rate of cervical cancer increased from 2.69/10 5 to 6.21/10 5, with an average annual growth rate of 13.1% ( P<0.05), and the trend of the age-standardized mortality rate was basically consistent with that of the crude mortality rate. The analysis of urban-rural differences showed that the growth rates of the crude incidence rate and crude mortality rate of cervical cancer in rural areas were higher than those in urban areas from 2010 to 2017 (AAPC incidence rate: 21.3% vs. 2.3%; AAPC mortality rate: 20.1% vs. 8.4%). The analysis of age differences showed that the crude incidence rate and crude mortality rate of cervical cancer in all age groups increased to varying degrees, among which the growth rate of the incidence rate (AAPC=16.2%, P<0.05) and mortality rate (AAPC=14.7%, P<0.05) of cervical cancer in women aged 65 and above was the fastest. In addition, the DALYs rate of cervical cancer in Guangxi increased from 50.6/10 5 in 2010 to 111.0/10 5 in 2017, with an average annual increase of 11.9% ( P<0.05). The growth rate of the DALYs rate in rural areas was higher than that in urban areas, and the growth rate of the DALYs rate in the 50-59 age group was higher than those in other age groups. Conclusions:From 2010 to 2017, the incidence rate, mortality rate and DALYs rate of cervical cancer in Guangxi showed an upward trend. Comprehensive prevention and control measures for cervical cancer, such as improving the early diagnosis and treatment system, promoting the popularization of HPV vaccination and strengthening health education, should be taken to reduce the disease burden of cervical cancer.
