Objective:To evaluate the clinical effect of combination of autologous tissue reconstruction of tarsal plate with temporal flap on repair of full-thickness lower eyelid defect.Methods:Eleven patients (11 eyes) underwent hard palate mucosa or ear cartilage combined the emporal flap with the orbicularis oculi muscle to repair full-thickness defect ofpalpebra inferior.Of the 11 patients,6 had more than 75％ eyelid defect area,and 5 had more than 50％ eyelid defect area.Results:All 11 eyes closed completely,with no entropion or ectropion,and returned to normal basically.Postoperative follow-up was performed for 6 months to 5 years,3 years and 4 months on average.The function and form of eyelid remained stable.Infection,leakage or contracture was not found on reconstruction tarsus.Conclusion:Reconstruction of eyelid with autogenous hard palate mucosa or ear cartilage combined the emporal flap with the orbicularis oculi muscle is a simple,convenient and effective method.

Objective:To learn about the epidemiological characteristics and trends of brucellosis in Ningxia Hui Autonomous Region (Ningxia), and to provide reference for formulation of brucellosis prevention strategies and identification of key areas.Methods:The case data from 2004 to 2019 were collected from the "China Disease Prevention and Control Information System Infectious Disease Monitoring and Reporting System", and descriptive epidemiological methods were used to analyze the distribution of cases (time, population, and regional distribution).Results:From 2004 to 2019, a total of 15 337 human brucellosis cases and 1 death case were reported in Ningxia. The average annual incidence rate was 15.21/100 000, ranging from 0.02/100 000 to 44.83/100 000. The difference in incidence rate in different years was statistically significant (χ 2 = 14 731.60, P < 0.001). Among them, from 2004 to 2010, the incidence rate was low, with an average annual incidence rate of 1.32/100 000; from 2011 to 2019, it entered a high incidence stage, with an average annual incidence rate of 24.83/100 000. Brucellosis occured in every month of the year, and the onset time was mainly in March to September, accounting for 71.60% (10 981/15 337); seasonal indexes from April to August was all > 100%, with obvious seasonality. The age of onset mainly concentrated in 20 - < 70 years old, accounting for 89.60% (13 742/15 337); males were significantly more than females, with a sex ratio of 2.66 ∶ 1.00 (11 141/4 196); the occupations were mainly farmers and herdsmen, accounting for 86.03% (13 194/15 337). Since 2014, cases had been reported in 22 counties (districts, cities) in the region, all of which were all severely endemic areas; the top three counties (districts) with incidence rate were Yanchi County (103.73/100 000), Hongsibao District (56.01/100 000) and Tongxin County (29.18/ 100 000), respectively, the difference between different regions was statistically significant (χ 2 = 3.80, P < 0.001). Conclusions:The incidence rate of brucellosis in Ningxia is on the rise, and the epidemic situation is severe. It is recommended to carry out active and effective intervention measures in areas with high incidence of brucellosis to curb the further spread of brucellosis.

Objective:To learn about the awareness of brucellosis prevention and control knowledge among people in key areas of Ningxia Hui Autonomous Region (Ningxia), and analyze influencing factors.Methods:From February to March 2023, a multi-stage stratified sampling method was adopted to select residents (aged ≥12 years and resident for ≥6 months) from Yanchi County, Litong District, Pingluo County and Yuanzhou District of Ningxia as the survey subjects. Demographic information such as gender, age, education level, marital status, occupation, region, urban-rural status, as well as knowledge of brucellosis prevention and control were obtained through face-to-face questionnaire surveys. The awareness rate of brucellosis prevention and control knowledge among various populations was calculated and the influencing factors were analyzed by binary logistic regression.Results:A total of 1 592 questionnaires were distributed, of which 1 581 were valid, with an effective rate of 99.31%. There were 704 males, accounting for 44.53% (704/1 581); and 877 females, accounting for 55.47% (877/1 581). The age was (54.09 ± 14.81) years old, ranging from 14 to 88 years old. The education level was mainly primary school or below, accounting for 48.07% (760/1 581). The marital status was mainly married or cohabitating, accounting for 91.84% (1 452/1 581). The occupation was mainly farmers and herdsmen, accounting for 61.92% (979/1 581). In Pingluo County, Litong District, Yuanzhou District and Yanchi County, 392, 403, 396 and 390 people were investigated, respectively. In urban and rural areas, 797 and 784 people were investigated, respectively. The overall awareness rate of brucellosis prevention and control knowledge among the population was 47.82% (756/1 581). Univariate analysis showed that there were statistically significant differences in the awareness rates of brucellosis prevention and control knowledge among different age groups, education levels, marital status, occupation, regions and urban and rural populations ( P < 0.05). Binary logistic regression analysis showed that age, education level, marital status, occupation, urban-rural status were the factors influencing the awareness rate of brucellosis prevention and control knowledge among the population ( P < 0.05). Conclusion:The awareness rate of brucellosis prevention and control knowledge in key areas of Ningxia is relatively low, and age, education level, marital status, occupation, and urban-rural status are the main influencing factors.
