Objective:To analyze the epidemiological characteristics, diagnosis and treatment of malaria in the peacekeeping mission area of the Democratic Republic of the Congo (DRC), and to evaluate the efficacy of artemisinin based combination therapy (ACT), to provide clinical basis for the diagnosis and treatment of malaria.Methods:The clinical data of malaria-infected peacekeepers admitted to the Chinese Secondary Hospital of the United Nations Stabilization Mission in DRC (MONUSCO) from January 2014 to September 2020 were collected, and the general information, incidence characteristics, treatment and clinical outcomes of the patients were retrospectively analyzed.Results:From January 2014 to September 2020, 362 peacekeepers were hospitalized with malaria, the average annual incidence case was 54 cases per year, and the annual incidence was 9.5/1 000, with a median of 2.5 days (1 - 9 days) from onset to diagnosis. Severe malaria accounted for 7.73% (28/362) and uncomplicated malaria accounted for 92.27% (334/362). The incidence rate was 37.57% (136/362) in the dry season (April to September) and 62.43% (226/362) in the rainy season (October to March of the following year). After ACT antimalarial treatment, all patients were cured clinically. Eight cases recurred and were cured clinically after drug conversion ACT retreatment.Conclusions:In the peacekeeping mission area of DRC, peacekeepers are generally susceptible to malaria. ACT has a high cure rate, safety and efficiency in clinical treatment.

Objective To study the clinical characteristics,diagnosis and clinical outcomes of neonatal purulent meningitis in southwest and northwest regions of China.Method There were 5 tertiary hospitals in southwest and northwest regions of China with well capacity of treating neonatal diseases collaborated as the neonatal meningitis network.From January 2010 to December 2014,clinical symptoms,signs and outcomes of cases with the diagnosis of neonatal meningitis were retrospectively studied.Result During the study period,a total of 63 514 neonates were admitted to 5 neonatal departments in Chongqing and Shanxi Province,China,and 407 cases were diagnosed of bacterial meningitis.255 (62.7％) cases were males.The mean gestational age was (37.1 ±3.2) weeks.125 (30.7％) were preterm infants and69 late-preterm infants.The mean birth weight was (2 859 ± 771) g,90 (22.1％) cases were low birth weight infant.The incidence of neonatal purulent meningitis were 0.64％ (From 2010 to 2014,0.30％,0.72％,0.64％,0.89％ and 1.12％ respectively),and 77.6％ of the cases were the late-onset infection.The mortality rate were 9.1％ (From 2010 to 2014,6.3％,4.0％,9.8％,8.4％ and 8.5％ respectively).The incidence of neurological sequelae was 5.9％ (From 2010 to 2014,12.5％,8.0％,6.1％,6.3％ and 11.6％ respectively).The mean duration of hospital stay was 21 days.Mean duration of antibiotic treatment was 19 days.The remission rate was 85.0％ (346/407).Conclusion From 2010 to 2014,on average,the incidence of neonatal purulent meningitis was 0.64％,mortality rate was 9.1％,neurological sequelae was 5.9％,and remission rate was 85.0％.Among these years the mortality and neurological sequelae of neonatal purulent meningitis were not decreasing.
