海口市2010—2020年输入性登革热流行病学特征

Objective This study intends to understand the epidemiological characteristics of imported dengue fever in Haikou city from 2010 to 2020, we provide references for dengue fever prevention and control in Haikou city. Methods The epidemiological investigation and laboratory nucleic acid test data of dengue fever cases in Haikou City from 2010 to 2020 were collected, and analyzed by Excel 2010 and SPSS 20.0 software, to describe the epidemiological characteristics of imported dengue fever cases. Results A total of 72 cases of imported dengue fever were reported in Haikou City from 2010 to 2020, 53 cases were imported from abroad (73.61%) and 19 cases were imported domestically (26.39%), all of which were mild. The number of imported cases from 2017 to 2019 increased by 1 321.68% compared with the average annual imported cases from 2010 to 2016. The cases were concentrated in the main urban area (97.22%), distributed in the streets in the main urban area. The peak of case imported occurred in August-November,in addition, the domestic imported cases were concentrated in September-October. The ratio of male to female was 2.27∶1, and the average age was (34.93 ±1.55) years old. Working, doing business and visiting relatives accounted for 84.22% in China. Overseas workers, business and tourism accounted for 77.78%. There was a significant difference in the reasons for going out between domestic and overseas imported cases (χ2=75.10,P< 0.05). Among the imported sources, Southeast Asia accounted for 94.34% of overseas imported cases, and Guangdong Province accounted for 57.89% of domestic imported cases. The median of onset to diagnosis was 3 days, the first diagnosis rate was 77.78% (56/72), and the screening rate of people who have been infected before entering the country was 28.57%. Most of the dengue viruses infected were type I and type II, accounted for 84.72%. Conclusion The imported cases of dengue fever in Haikou city have gradually changed from scattered occurrence to rapid growth; we should strengthen the publicity and education of dengue fever among migrant workers, businessmen, tourists and relatives in the main urban area of Haikou City, and improve the awareness of disease prevention and medical treatment, strengthen quarantine inspection and medical examination of entry personnel from Southeast Asian countries as well as dengue fever diagnosis and treatment training in grass-roots medical institutions, which can effectively reduce the risk of local transmission caused by imported dengue fever cases. © 2021 Editorial Office of Chinese Journal of Schistosomiasis Control.

核苷(酸)类似物治疗慢性乙型肝炎患者HBV逆转录酶区变异的研究

目的分析核苷(酸)类似物治疗的慢性乙型肝炎患者HBV逆转录酶区耐药相关变异位点、变异位点组合模式、HBV DNA水平和HBeAg等特征,为临床应用核苷(酸)类似物抗乙肝病毒治疗提供参考。方法纳入研究的141例慢性乙型肝炎患者,使用NAs治疗的107例为治疗组,未使用药物抗病毒治疗的34例为对照组。采用线性探针反向杂交法(PCRRLP)检测HBV逆转录酶区耐药相关变异位点,实时荧光定量PCR法检测乙型肝炎病毒DNA水平,酶联免疫吸附试验检测乙肝免疫标记物,并对耐药相关变异的特点和研究病例的临床资料进行统计学分析。结果核苷(酸)类似物治疗效果不佳组耐药相关变异检出率(82.5%)明显高于未治疗的对照组(5.9%)和抗病毒治疗有效组(有效组10例未检出耐药相关变异)(P0.01)。97例核苷(酸)类似物抗病毒效果不佳的病例中80例检出140个耐药相关变异位点,包括rtM204I 45个、rtM204V 32个、rtA181V 28个、rtL180M 25个、rtN236T 10个;变异位点组合模式主要有:rtL180M+rtM204I、rtM204V、rtM204I+rtM204V、rtA181V+rtM204V、rtM204I、rtA181V+rtN236T等;51个对NAs应答不佳病例耐药变异检出率70.59%,46个病毒学突破病例耐药变异检出率95.65%,差异明显(P0.01)。NAs单药治疗病例早于多药治疗病例检出耐药相关位点(P0.01);NAs治疗时间越长,耐药变异检出率越高(P0.01);病例HBV-DNA水平等级越高,耐药变异检出率也越高(P0.01)。结论⑴NAs治疗慢性乙型肝炎可导致HBV逆转录酶区变异,NAs抗乙型肝炎病毒效果不佳与HBV逆转录酶区变异密切相关;⑵不同NAs药物导致慢性乙肝患者HBV逆转录酶区变异位点、变异模式特点不同;⑶NAs治疗慢性乙型肝炎的用药种类与方式、治疗时长,患者HBV-DNA水平等对HBV逆转录酶区发生耐药变异均可能产生重要影响。提示在NAs治疗前、治疗过程合适时间点检测NAs耐药相关变异位点和HBV DNA水平,可为临床慢性乙型肝炎的抗病毒治疗提供重要参考。

特大车祸遇难者及家属创伤后应激障碍调查分析

异位妊娠是妇产科常见的急腹症之一,发病率约为1%,并有逐年增加的趋势,也是孕产妇死亡的主要原因之一,故一直视为具有高度危险的妊娠早期并发症[1].但近几年来随着阴道B超,血β-HCG检测技术的提高,以及妇产科医生对异位妊娠警惕性的提高,早期诊断出异位妊娠并不困难,从而为未破裂前异位妊娠药物治疗创造了条件.现将我院使用甲氨蝶呤(MTX)联合米非司酮治疗异位妊娠的情况报道如下:
