Objective:
To evaluate the immunogenicity and safety of co-administration with bivalent human papillomavirus (HPV) vaccine and hepatitis E virus (HEV) vaccine, so as to provide reference for optimizing the vaccination schedule.
Methods:
Females aged 18 to 25 years were recruited from September to October 2021 in Hengdian College of Film & Television in Zhejiang Province and randomly divided into the HPV+HEV group, the HPV group, and the HEV group. The vaccination procedures were one dose each at 0, 1, and 6 months. Immunogenicity was evaluated by detecting the geometric mean titers (GMT) of HPV16 IgG, HPV18 IgG, and/or HEV IgG antibodies before the first vaccination and one month after the full course of immunization, and comparing the difference in seroconversion, and the GMT ratio. The non-inferiority margin was set at a seroconversion difference of ≤5%, and the lower limit of the 95%CI of the GMT ratio was >0.5. Safety was evaluated by collecting conjunctive local reactions/events and systemic reactions/events within 7 days after each dose, non-conjunctive adverse events within 30 days after each dose, and serious adverse events throughout the observation period (0 to 7 months).
Results:
A total of 240 females were included, among whom 236 completed the full vaccination program, including 79 in the HPV+HEV group, 77 in the HPV group, and 80 in the HEV group. One month after the full course of immunization, the seroconversion rates of HPV16 IgG and HPV18 IgG antibodies in both the HPV+HEV group and the HPV group were 100%, and the differences in seroconversion rates were 0 (95%CI: -3.39%-+∞). The seroconversion rates of HEV IgG antibodies in both the HPV+HEV group and the HEV group were 100%, and the difference in seroconversion rates was 0 (95%CI: -3.27%-+∞). The GMT of HPV16 IgG and HPV18 IgG antibodies in the HPV+HEV group was 393.88 and 284.86 IU/mL respectively, which was not inferior to 489.39 and 341.24 IU/mL in the HPV group, and the GMT ratios were 0.80 (95%CI: 0.66-+∞) and 0.83 (95%CI: 0.68-+∞), respectively. The GMT of HEV IgG in the HPV+HEV group was 13.55 U/mL, which was not inferior to 12.72 U/mL in the HEV group, and the GMT ratio was 1.07 (95%CI: 0.92-+∞). The incidences of pain, pruritus, and induration in the HPV+HEV group were 54.43%, 21.52% and 40.51% respectively, which were significantly higher than 10.39%, 0, and 0 in the HPV group (all P<0.05). The incidences of redness/swelling, muscle pain/general weakness in the HPV+HEV group were 2.53% and 0, respectively, which were significantly lower than 12.50% and 16.25% in the HEV group (both P<0.05).
Conclusion
The co-administration of the bivalent HPV vaccine and HEV vaccine is not inferior to individual vaccination in terms of immunogenicity and safety, and the vaccination plan can be optimized through co-administration.

OBJECTIVE:
To observe the clinical effect of internal heat acupuncture therapy for knee osteoarthritis of early to middle stages, and explore its influence on cartilage thickness.
METHODS:
A total of 44 patients with knee osteoarthritis of early to middle stages were treated with internal heat acupuncture therapy at ashi points (most of them are located at the subpatellar fat pad, both sides of the patellar ligament, the tendon of the quadriceps and the attachment of the medial and lateral collateral ligaments), once a week, a total of 4 weeks of treatment. Before and after treatment, after 3 months of treatment completion (in the follow-up), the visual analogue scale (VAS) score, Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score, frequency of 30-second chair stand test (30sCST), cartilage thickness of femoral intercondylar and knee joint ultrasound score were compared, and the clinical effect was evaluated.
RESULTS:
After treatment, the VAS、WOMAC and knee joint ultrasound scores were reduced (P<0.05), frequency of 30sCST was increased (P<0.05) compared with those before treatment; in the follow-up, the VAS、WOMAC scores were reduced (P<0.05), frequency of 30sCST and cartilage thickness of femoral intercondylar were increased (P<0.05) compared with those before treatment. After treatment, the total effective rate was 93.2% (41/44), in the follow-up, the total effective rate was 95.5% (42/44).
CONCLUSION
Internal heat acupuncture therapy is effective in the treatment of knee osteoarthritis of early to middle stages, could relieve the pain, improve the joint function, and delay cartilage degeneration and disease progression.

OBJECTIVES:
To analyze the differential expression and biological functions of circRNAs in the anterior lens capsules of high myopic patients with cataract and their pathogenic roles in the development of this condition.
METHODS:
Anterior lens capsule specimens were collected intraoperatively from 36 patients with age-related cataract (ARC) and 36 high myopic patients with cataract. Among these, 18 specimens from each group were selected for whole transcriptome sequencing and biological analysis, and the remaining 36 specimens were used for validation of circPDGFRA, circFOXJ3, hsa_circ_0004767, hsa_circ_0007528, ciCRIM1, circMAN1A2, circSLC5A3, and circPTK2 expressions using RT-qPCR. hsa_circ_0007528 was selected for cell experiments to examine its effects on proliferation, migration, and apoptosis of lens epithelial cells (LECs).
RESULTS:
A total of 16 192 circRNAs were detected in the specimens from both groups, among which 62 circRNAs were differentially expressed (29 upregulated and 33 downregulated). GO and KEGG analyses revealed that the differentially expressed circRNAs were primarily localized in the cytoplasm, nucleoplasm, and endoplasmic reticulum, and were involved in signaling pathways associated with Gap junction and the PI3K-Akt, NF-κB, Jak-STAT, HIF-1, and MAPK signaling pathways. The ceRNA network predicted multiple target genes. RT-qPCR validation results were consistent with the sequencing data. In the LECs, upregulation of hsa_circ_0007528 significantly inhibited cell proliferation and migration and obviously promoted cell apoptosis.
CONCLUSIONS
The expression profile of circRNAs in the anterior lens capsule of high myopic patients with cataract differs from that of ARC patients. Upregulation of hsa_circ_0007528 inhibits LEC proliferation and migration and promotes cell apoptosis.

Salmonellosis represents a global epidemic, and the emergence of extensively drug-resistant (XDR) Salmonella and its sustained transmission worldwide constitutes a significant public health concern. Flagellum-mediated motility serves as a crucial virulence trait of Salmonella that guides the pathogen toward the epithelial surface, enhancing gut colonization. Artemisia argyit essential oil, a traditional herb extract, demonstrates efficacy in treating inflammation-related symptoms and diseases; however, its effects on flagellum assembly and expression mechanisms in anti-Salmonella activity remain inadequately explored. This study aimed to elucidate the mechanism by which Artemisia argyit essential oil addresses Salmonella infections. Network pharmacological analysis revealed that Traditional Chinese Medicine (TCM) Artemisia argyit exhibited anti-Salmonella infection potential and inhibited flagellum-dependent motility. The application of Artemisia argyit essential oil induced notable motility defects through the downregulation of flagellar and fimbriae expression. Moreover, it significantly reduced Salmonella-infected cell damage by interfering with flagellum-mediated Salmonella colonization. In vivo studies demonstrated that Artemisia argyit essential oil administration effectively alleviated Salmonella infection symptoms by reducing bacterial loads, inhibiting interleukin-1 beta (IL-1β), IL-6, and tumor necrosis factor-alpha (TNF-α) production, and diminishing pathological injury. Gas chromatography-mass spectrometry (GC-MS) analysis identified forty-three compounds in Artemisia argyit essential oil, with their corresponding targets and active ingredients predicted. Investigation of an in vivo model of Salmonella infection using the active ingredient demonstrated that alpha-cedrene ameliorated Salmonella infection. These findings suggest the potential application of Artemisia argyit essential oil in controlling Salmonella, the predominant food-borne pathogen.

Objective To evaluate the molluscicidal effect of spraying 5% niclosamide ethanolamine salt granules with drones against of Oncomelania hupensis snails in snail habitats in marshland areas. Methods From September to October, 2022, marshlands were sampled from Dantu District, Zhenjiang City, Jiangsu Province as study areas, and assigned into four groups, of approximately 3 000 m2 per group. In Group A, environmental cleaning was performed, followed by spraying 5% niclosamide ethanolamine salt granules with knapsack sprayers at a dose of 40 g/m2, and in Group B, 5% niclosamide ethanolamine salt granules were sprayed with knapsack sprayers at a dose of 40 g/m2 without environmental cleaning, while in Group C, environmental cleaning was conducted, followed by spraying 5% niclosamide ethanolamine salt granules with drones at a dose of 40 g/m2, and in Group D, 5% niclosamide ethanolamine salt granules were sprayed with drones at a dose of 40 g/m2 without environmental cleaning. Then, the study areas in each group were equally divided into six blocks, with Block 1 for baseline surveys and blocks 2 to 6 for snail surveys 1, 3, 5, 7, 14 days following chemical treatment. The mortality of snails and the reduction of the density of living snails were calculated. Results A total of 132 frames were surveyed during the period from September to October 2022, and the occurrence of frames with living snails and means density of living snails were 61.36% (81/132) and 1.58 snails/0.1 m2, respectively. The overall mortality rates of snails were 43.02% (77/179), 38.69% (77/199), 47.78% (86/180) and 31.02% (58/187) 14 days following chemical treatment in groups A, B, C and D, respectively (χ2 = 11.646, P < 0.05), and there were differences detected in the snail mortality between group A and D, and between groups C and D (both Padjusted values < 0.05). The adjusted mortality rates of snails were 37.42%, 36.07%, 38.85% and 40.40% in groups A, B, C and D 14 days post-treatment, and the density of living snails decreased by 48.10%, 63.29%, 67.09% and 69.62% 14 days post-treatment relative to pre-treatment, respectively. Conclusions Chemical treatment with drones is feasible for O. hupensis snail control in marshland areas; however, the molluscicidal effect of spraying 5% niclosamide ethanolamine salt granules with drones is comparable to spraying chemicals manually in marshland areas regardless of environmental cleaning.
