Results A total of 41 county-level schistosomiasis diagnostic network laboratories were built in national schistosomiasis surveillance sites of Hunan Province, and 36 met the requirements for the construction of the national schistosomiasis diagnostic network laboratory in China, which were approved for inclusion in the province-level schistosomiasis diagnostic network laboratory. During the six inter-laboratory comparisons performed by the national schistosomiasis diagnostic reference center of China, full consistency was achieved by 3 county-level schistosomiasis diagnostic network laboratories in Hunan Province, and the coincidence rates for re-review of serological and pathogenic detection samples were 98.40% and 100%, respectively. Conclusions The county-level schistosomiasis diagnostic network laboratory system has been preliminarily built and under effective operation in Hunan Province; however, the building capability remains to be improved.Objective To examine the effect of rational emotive therapy on negative emotions among advanced schistosomiasis patients with repeated hospitalizations. Methods A total of 97 advanced schistosomiasis patients with anxiety and depressive emotions that were hospitalized in Xiangyue Hospital of Hunan Institute of Schistosomiasis Control for three times or more were enrolled, and given rational emotive therapy for 4 weeks in addition to routine nursing care. The scores for anxiety, depression and quality of life were estimated in patients before and after the rational emotive therapy using the Self-Rating Anxiety Scale (SRS), the Self-Rating Depression Scale (SDS) and WHOQOL-BREF Form. Results The SAS and SDS scores were significantly lower 4 weeks following rational emotive therapy than before the intervention (SAS score, 45.40 ± 7.77 vs. 59.25 ± 9.29, t = 14.021, P less then 0.01; 51.48 ± 8.01 vs. 63.93 ± 9.59, t = 12.991, P less then 0.01). The percentages of patients with moderate and severe anxiety and depression were significantly lower 4 weeks following rational emotive therapy than before the intervention (P less then 0.01), and the scores for each item in the quality of life were all significantly greater 4 weeks following rational emotive therapy than before the intervention (P less then 0.01). Conclusions Rational emotive therapy may improve the negative emotions and the quality of life of advanced schistosomiasis patients with repeated hospitalizations.Objective To compare the expression of serum vitamin D in advanced schistosomiasis patients with grade I and II hepatic fibrosis, and to preliminarily examine its associations with the internal diameter of the main portal vein and progression of hepatic fibrosis. Methods The medical records of 126 advanced schistosomiasis patients with grade I and II hepatic fibrosis referred to Jiaxing First Hospital from March 2012 to September 2015 were retrospectively analyzed. The internal diameter of the main portal vein and serum 25-hydroxyvitamin D3 [25(OH)D3] level were measured. The progression of hepatic fibrosis was followed up, and the serum vitamin D level was compared between patient with disease progression and stable disease. Results The 126 advanced schistosomiasis patients included 72 men and 54 women, and had ages of 62 to 80 years. link2 There were 58 cases with grade I hepatic fibrosis and 68 cases with grade II hepatic fibrosis. There were significant differences between patients with grade I and II hepatic fis patients with hepatic fibrosis, and it may be associated with the internal diameter of the main portal vein and the progression of hepatic fibrosis disease.Objective To analyze the endemic situation of schistosomiasis in national surveillance sites of Anhui Province from 2015 to 2018, so as to provide scientific evidence for schistosomiasis control and prevention in Anhui Province. Methods According to the National Schistosomiasis Surveillance Programme (2014 version), a total of 51 national schistosomiasis surveillance sites were assigned in Anhui Province in 2015, and Schistosoma japonicum infections in humans and livestock and snail distribution were monitored from 2015 to 2018. Results A total of 89 638 local residents and 42 609 mobile populations received serological screening of schistosomiasis in 51 national surveillance sites of Anhui Province from 2015 to 2018, and the sero-prevalence of S. japonicum infections was 1.41% to 3.69% in local residents and 0.84% to 2.13% in mobile populations, respectively. There were 5 egg-positive local residents and 1 egg-positive mobile populations detected in 2015, with occupations of farmers and fishermen. There were 6 405 livestock detected for S. japonicum infections, and no egg-positives were identified. Among an area of 12 661 hm2 surveyed in the national schistosomiasis surveillance sites of Anhui Province from 2015 to 2018, the areas of snail habitats were 2 461.27 to 2 628.96 hm2, andthemeandensityoflivingsnailswas 0.3757 to 0.4330 snails/0.1 m2, with no S. japonicum infections identified in snails. Conclusions The endemic situation of schistosomiasis is at a low level in Anhui Province; however, the risk of schistosomiasis transmission remains in local regions of the province.

Methods All data pertaining to the epidemic status of malaria and malaria case were captured from Henan Province in 2018, and the epidemic status of malaria and the diagnosis and treatment of malaria cases were analyzed using a descriptive epidemiological method. Results A total of 174 malaria cases were reported in Henan Province in 2018, with a male-to-female ratio of 33.8∶1. The cases were predominantly found at 30- and 40- years, and farmer was the highest-risk population. All cases were imported for overseas countries and 96.55% (168/174) were from Africa. The cases were reported across 17 cities of the province, and 63.22% (110 cases) were detected in 4 cities of Zhengzhou, Luoyang, Xuchang and Puyang. Both the median duration from onset to initial admission and the median time from the initial admission to definitive diagnosis were 1 d. There were 6 cases (3.45%) with more than 7 days to visit a doctor, and there were 13 cases (7.47%) with definitive diagnosis of over 7 days (delay in definitive diagnosis). All malaria cases were reported within 24 h, and 98.28% (171/174) completed case investigations within 3 d. All 18 cities had achieved malaria elimination by December 2018. Conclusions All malaria cases reported in Henan Province in 2018 are imported from overseas countries. Intensifying malaria surveillance among returnees from Africa and Southeast Asia and timely identification and treatment of imported malaria cases are required to prevent the development of secondary malaria cases, so as to ensure the achievement of malaria elimination in Henan Province on schedule.Objective To evaluate the indoor effect of six human metabolic compounds for trapping adult Culex pipiens quinquefasciatus. Methods The effects of six human metabolic compounds alone (acetic acid, propionic acid, octanoic acid, lactic acid, 1-octene-3-alcohol and urea alone), liquid lactic acid, acetic acid, propionic acid, octanoic acid, lactic acid or 1-octene-3-alcohol in combination with urea at an equal mass ratio, and lactic acid-urea combinations at various mass ratios, for trapping Cx. p. quinquefasciatus were examined using the trapping method, while the dechlorinated water served as a control. Results The indoor mosquito-trapping efficacy of the six human metabolic compounds was all superior to the dechlorinated water. Acetic acid, propionic acid, octanoic acid, or 1-octene-3-alcohol combined with urea at a mass ratio of 1∶1 had a comparable mosquito-trapping efficacy with acetic acid, propionic acid, octanoic acid, or 1-octene-3-alcohol alone (all P values > 0.05). The lactic acidurea combination a used at home and office environments.Objective To evaluate the effects of Cu2+ and Cd2+ at different concentrations on superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) activity in Oncomelania hupensis. Methods Cu2+- and Cd2+-containing solutions were prepared at 7 concentrations, and O. hupensis snails were exposed to the solutions for 24 h, of 15 snails in each concentration. Then, the snail body was collected following removal of the snail shell and homogenated, and the SOD, CAT and POS activities were detected in the supernatants. Results With the increase of the Cu2+ concentration, the SOD activity appeared a rise followed by a reduction in O. link3 hupensis snails, and the CTA activity appeared a decline-rise-decline tendency, while the POD activity showed a tendency towards rise followed by decline. With the increase of the Cd2+ concentration, the SOD activity appeared a rise followed by a reduction in O. hupensis snails, and the CTA activity appeared a decline- rise- decline tendency, while the POD activity showed a decline-rise-decline tendency. Conclusions Exposure to Cu2+ and Cd2+ at high concentrations results in a decline in the activity of SOD, CAT and POD in O. hupensis at the same time.Objective To investigate the risk of Anisakis infections among high-risk populations along the coastal areas of Jiangsu Province, so as to develop the strategy for the prevention and control of anisakiasis in the province. Methods Three counties along the coastal areas of Jiangsu Province were selected as the study sites in 2018, including Rudong County in Nantong City, Haizhou District in Lianyungang City and Dongtai City in Yancheng City. The knowledge, attitude and practice (KAP) of anisakiasis prevention and control, and the prevalence of serum specific IgG antibody against Anisakis were investigated among high-risk populations among these three study sites, including fishermen, fish seller and people who liked eating fresh and live marine fish. Factors affecting the prevalence of the specific IgG antibody against Anisakis were identified using a multiple logistic regression model. In addition, Anisakis larvae infections were detected in fresh and live marine fish samples collected from local markets, andfish detected, the prevalence and intensity of Anisakis larvae infection was 64.0% and 8.1 larvae per fish, with high prevalence seen in Trichiurus haumela and Pneumatophorus japonicas. Conclusions The awareness of anisakiasis prevention and control knowledge is low among the high-risk populations living along the coastal areas of Jiangsu Province, and there are high-risk behaviors, such as eating raw or half-cooked food, using the same chopping board for raw and cooked food. In addition, the prevalence of Anisakis infections is high in the marine fish in these areas. Therefore, the health education and health promotion for anisakiasis prevention and control should be intensified.
