Objective To evaluate the effect of comprehensive schistosomiasis control measures based on infection source control in Hanchuan City marshland and lake endemic regions . Methods The data of comprehensive schistosomiasis control in Hanchuan City from 2004 to 2013 were collected and the change trends of the Oncomelania hupensis snail status and the in?fection situation of human and livestock were analyzed to evaluate the control effect. Results After the implementation of the comprehensive measures the infection rates of residents and cattle decreased from 6.38%and 8.11%in 2004 to 0.16%and 0 in 2013 respectively. There were no acute schistosomiasis patients since 2007 no new infection cases since 2011 and no infected snails since 2012. Compared with 2004 the occurrence rate of frames with living snails and the average density of living snails decreased by 56.78%and 68.35% respectively but the snail area and susceptible area increased by 0.62%and 7.10% respec?tively. In 2013 all the 367 endemic villages in 26 townships reached the criteria of transmission controlled. Conclusions The comprehensive schistosomiasis control measures based on infection source control can control the schistosomiasis transmission effectively in marshland and lake endemic regions. When consolidating the achievement the snail area in inner embankment should be compressed to prevent the schistosome re?infection in human and livestock.

Angioimmunoblastic T-cell lymphoma (AITL) is an aggressive peripheral T-cell lymphoma (PTCL) that originates from follicular helper T cells (TFH). It has the highest incidence in PTCL which is second only to PTCL-not otherwise specified (PTCL-NOS). Its clinicopathological diagnosis is difficult, it is easy to be misdiagnosed and missed, and the prognosis is poor. This article reviews the pathogenesis, clinical and pathological characteristics as well as treatment progress of AITL, in order to provide a reasonable basis for clinical diagnosis and treatment of the disease.

Objective:To investigate the value of real-time shear wave elastography (SWE) in the assessment of splenic congestion in patients with chronic right heart failure.Methods:Sixty patients with chronic right heart failure with cardiac function grade Ⅱ-Ⅳ of New York Heart Association (NYHA) treated in Lianyungang First People′s Hospital from March 2020 to February 2021 were collected as the study group, and 20 healthy subjects in the same period were selected as the control group. Routine echocardiography was performed on all subjects; spleen stiffness measurement (SSM) was detected by SWE, and blood biochemical indicators related to patients with right heart failure were detected and recorded. SSM and other related parameters between the two groups were analyzed; the SSM in patients of different cardiac function classifications and course of disease were compared; 60 patients were divided into low SSM group (SSM≤15.0 kPa), middle SSM group (15.0 kPa
