Objective To analyze the epidemiological characteristics and immunization history of pertussis cases in Yichang City, Hubei Province from 2018 to 2023. Methods Data on the incidence and immunization history of pertussis cases were collected in Yichang City from 2018 to 2023, and the epidemiological characteristics was analyzed and described. Results A total of 109 cases of pertussis were reported in Yichang from 2018 to 2023, and the annual average reported incidence rate was 0.45/100,000. The incidence rate reported in each year was between 0～1.58/100,000. The area with the highest annual reported incidence rate was Xiling District (1.19/100,000). There was a statistically significant difference in the incidence rate between different years (χ²=208.26, P < 0.001). The annual reported incidence rate showed a significant increasing trend (χ² trend =125.71, P < 0.001). The ratio of male to female cases was 1.22. There was no significant difference in the annual reported incidence rates between males and females (χ²=0.85, P=0.36). Children aged 3-9 years accounted for 60.55%. Students and scattered children accounted for 45.87% and 36.70%, respectively. Before the onset of the disease, 72.48% had a history of immunization with pertussis-containing vaccine, and 27.52% had no history of immunization. The shortest interval between the last dose of pertussis-containing vaccine and the onset of the disease was 8 days, the longest was 4057 days, and the median was 1882 days. Conclusion From 2018 to 2023, the reported incidence of pertussis in Yichang City has been on the rise, with the majority of cases occurring in children and students under the age of 9.

Objective:To investigate the clinical effect of anterolateral thigh perforator flap (ALTPF) combined with transfer of fascia lata in reconstruction of complex tissue defects of hand and foot.Methods:From July 2021 to October 2023, 9 patients with complex tissue defects of hand and foot were treated with ALTPF combined with fascia lata in the Department of Orthopaedic Microsurgical Repair and Reconstruction of Fuyang People's Hospital Affiliated to Anhui Medical University. There were 2 males and 7 females with an average age of 28.1 (range, 4-65) years old. Three patients had extensor tendon defects in 6 digits of dorsal hands, 5 had extensor tendon defect in 10 toes of dorsal foot, 1 had a defect of anterior tibial tendon and 1 had Achilles tendon defect in posterior ankles. The sizes of soft tissue defect ranged from 8.0 cm×6.0 cm to 15.0 cm×10.0 cm, and the lengths of tendon defect ranged from 6.0 to 13.0 cm. Preoperative Doppler ultrasound was used to locate the distribution of perforating branches in the anterolateral thigh region. According to the characteristics of wound, ALTPFs and fascia lata were designed and harvested. Fascia lata with an appropriate size of 1.5 cm×8.0 cm-4.5 cm×15.0 cm were taken to bridge the defects of the tendon and the Achilles tendon. The wounds were reconstructed with flaps sized 9.0 cm×6.5 cm-18.0 cm×7.5 cm. Nine fascia lata donor sites and 8 flap donor sites were sutured directly. One donor site was treated with a skin graft of ipsilateral ilioinguinal region. The survival and complications of the flaps and donor sites were observed through outpatient follow-up visits, WeChat reviews and home visits, etc. The hand function was assessed according to the Evaluation Standard of Upper Limb Functional of Hand Surgery of Chinese Medical Association, and the foot and ankle function was assessed according to the Mazur score standard of joint range of motion and motor function.Results:All patients were included in follow-up for 4-24 (mean, 13.4) months with complete clinical data being collected. All 9 ALTPFs survived and healed primarily. A linear scar left in donor sites in 8 patients, and mild lamellar scar at skin graft in 1 patient. Texture and colour of the flaps were similar to the surrounding tissue without secondary flap thinning surgery. Combined with postoperative rehabilitation training, satisfactory function recoveries were achieved. Hand function of 3 patients were evaluated according to Evaluation Standard of Upper Limb Functional of Hand Surgery of Chinese Medical Association, 2 patients were excellent and 1 was good. Ankle and foot functions in 6 patients were evaluated according to the range of motion of ankle and foot and Mazur score standard for motor function, 4 patients were excellent and 2 were good.Conclusion:ALTPF combined with fascia lata transfer can reconstruct the complex tissue defects of hand and foot. Of which, 1 donor site can meet the requirements of 2 types of tissues reconstruction at the same time, and with minimal damage to the donor site as well as an precise reconstruction of the recipient site. It avoids staged surgery, shortens the treatment time and reduces the cost of treatment.

Objective:To study the molecular phylogeny and virulence gene profile of Francisella salimarina. Methods:Phylogenetic analysis of Francisella salimarina was performed based on the global genome data of related Francisella species on GenBank database. The consistency in phylogenetic analysis based on single marker genes (such as 16S rRNA gene, rpoB gene and mdh gene) and the core genome as compared. Virulence genes and antibiotic resistance genes were annotated using the virulence factor database (VFDB) and the Comprehensive Antibiotic Resistance Database (CARD), respectively. The virulence of Francisella salimarina was analyzed with a Galleria mellonella (greater wax moth) infection model using Francisella philomiragia ATCC 25015 T as reference strain. Results:The phylogenetic analysis revealed that Francisella salimarina was closely related to Francisella philomiragia. The phylogenetic tree based on mdh gene was highly similar to that based on the core genome. Francisella salimarina could be differentiated from other related species by 16S rRNA gene or mdh gene, with the latter being more accurate. Eight Francisella salimarina strains carried multiple virulence genes, mainly involved in secretion, adhesion, immune regulation, motility and stress survival. Moreover, beta-lactam resistance gene blaFPH was identified in all eight strains. Francisella salimarina showed high lethality in the Galleria mellonella infection model, which was similar to Francisella philomiragia ATCC 25015 T. Conclusions:Francisella salimarina was a rare pathogen with similar pathogenicity to Francisella philomiragia. The mdh gene could be used as a molecular target for rapid identification of Francisella salimarina.

Recent studies have revealed great functional and structural heterogeneity in the ribbon-type synapses at the basolateral pole of the isopotential inner hair cell (IHC). This feature is believed to be critical for audition over a wide dynamic range, but whether the spatial gradient of ribbon morphology is fine-tuned in each IHC and how the mitochondrial network is organized to meet local energy demands of synaptic transmission remain unclear. By means of three-dimensional electron microscopy and artificial intelligence-based algorithms, we demonstrated the cell-wide structural quantification of ribbons and mitochondria in mature mid-cochlear IHCs of mice. We found that adjacent IHCs in staggered pairs differ substantially in cell body shape and ribbon morphology gradient as well as mitochondrial organization. Moreover, our analysis argues for a location-specific arrangement of correlated ribbon and mitochondrial function at the basolateral IHC pole.
