    Macrophages are important components in human innate immune system. They are highly plastic and can differentiate into pro-inflammatory M1 and anti-inflammatory M2 under the stimulation of different microenvironmental signals. Polarization of macrophages is regulated by many signaling pathways and transcription factors, and M1/M2 phenotype are involved in the occurrence and development of a variety of diseases, such as tumor, type Ⅱ diabetes and severe acute pancreatitis, etc. In this paper, we reviewed the main signaling pathways related to macrophage polarization and its polarization state in common disorders, and described the importance of balance of macrophage polarization in maintaining homeostasis, with an attempt to provide new ideas for related clinical research.

    Role of ATP-P2X7R axis in inflammatory diseases
    YAN Shi-yi, CHEN Shi-yao, GUAN Fei, LEI Jia-hui
    Journal of Tropical Diseases and Parasitology    2022, 20 (1): 50-56,60.  
    Abstract1243)      PDF (1170KB)(5151)      
    In addition to being an energy source, adenosine triphosphate (ATP) can also bind to purinergic receptor 2X7 (P2X7R) on the cell surface to activate downstream related signaling pathways and initiate various pathophysiological reactions. P2X7R is widely expressed on many immune cells, such as macrophages, monocytes, lymphocytes and eosinophils, etc. ATP-mediated P2X7R pathways can play important roles in inflammatory diseases. This paper reviewed the basic concepts, discovery history, main sources and physiological and pathological functions of related molecules involved in P2X7R, and the role of ATP-P2X7R signaling pathway in inflammatory diseases of digestive system, respiratory system, nervous system and immune system.

    Abstract1012)      PDF (884KB)(4356)      
    China is a country with parasitic diseases being widespread, some of which seriously bring harm to people's health and hinder economic and social development. Since the founding of the People's Republic of China, the Party and the state have attached great importance to the prevention and control of parasitic diseases, and remarkable achievements have been made in the prevention and control of parasitic diseases in China. However, with the increase of international exchanges, the change of ecological environment and the transformation of production and life style, uncommon or rare parasitic diseases occur frequently, which should be deserved great attention. In this paper, the types and classification of parasitic diseases in China were introduced, and the prevalence, prevention and control of common parasitic diseases in China were summarized. The concepts, types and diagnoses of uncommon or rare parasitic diseases were discussed in order to provide reference for colleagues in this field.

    WANG Xu, SHEN Yu-juan, CAO Jian-ping
    Journal of Tropical Diseases and Parasitology    2022, 20 (3): 136-148.  
    Abstract1152)      PDF (1049KB)(4232)      
    Protozoa of Cryptosporidium spp. can be transmitted through the activities of humans and animals, causing human cryptosporidiosis, which was considered as one of the six most important pathogens of diarrhea in the world. It is a great threat to children and immunocompromised people, and may cause outbreak of public health events. However, there are no effective drugs or vaccines for the treatment and prevention of this infection at present. Therefore, the prevention and control of cryptosporidiosis is extremely difficult, and has attracted more and more attention around the world. In this paper, we summarized the situation of cryptosporidium infection in human over 30 years since the first case of cryptosporidiosis was reported in China in 1987, discussed the risk factors of Cryptosporidium transmission such as water and food contamination, infection of domestic animals, and seasonal epidemic situation, and introduced the progress, challenges and strategies of cryptosporidiosis control in China. Based on the existing survey and research results, Cryptosporidium spp. that can infect humans are widely distributed in China, and patients of HIV/AIDS or malignant tumor and drug addicts are susceptible population that call for attention. The main pathogenic species include C. hominis and C. parvum.. Considering the risk factors and prevention and control status of cryptosporidiosis, comprehensive prevention and control strategies should be implemented in terms of monitoring networks, prevention and control measures, technologies, water purification and health education, and the "One Health" public health concept should be practiced in all links of "parasites-humans- reservoir host-environment", so as to achieve effective monitoring and control of cryptosporidiosis in China.

    Abstract1584)      PDF (419KB)(4043)      

    【Abstract】 Objectives  To analyze the clinical and epidemiological characteristic of imported loaiasis in patients in Beijing. Methods  Field epidemiological study was performed pertaining to the patients’ previous activities, sources of infection and treatment as well as clinical pictures. Results  A total of 5 cases of confirmed loaiasis were reported in Beijing from 2011 to 2015. The disease was generally imported from Nigeria, Gameroon, Republic of Congo and Gabon. Increased ratio of eosinophils was seen in the five patients, in whom 3 had simple Calabar swellings, 1 had eye symptoms and skin itching, and another 1 had Calabar swellings and sense of worm migration at the conjunctiva. Conclusion  Imported disease may be increased with more international communication. Loaiasis is hard to diagnose, yet accurate diagnosis of this disease can rely on its characteristic symptoms and epidemiology.

    Objective To analyze the epidemiological characteristics and changing trends in patients infected with HIV/AIDS in Hefei area for evidence to formulate corresponding prevention and control measures. Methods The case data, reported in Hefei area from January 1, 1997 to December 31, 2022, were initially retrieved from China Information System for Disease Control and Prevention, and then analyzed regarding the distribution characteristics of time, population and region in the victims of HIV/AIDS. Joinpoint regression was performed to analyze the changing trends in such patients. Results In total, 3 974 HIV/AIDS cases were cumulatively reported in Hefei area from 1997 to 2022. Of the victims, 3 608 (90.79%) were males, and 366 (9.21%) females. The ratio of male to female was 9.86∶1. The age ranging from 20 to 29 years was dominant (1 511 cases, 38.02%). After 2008, the proportion of 50 years old and above tended to grow in the reported cases (χ2trend=62.73, P<0.05). The infection was most seen in patients with college or higher educational background (1 670 cases, 42.02%). By occupation, the reported case number was large in service industry (1 805 cases, 45.42%). The proportion of cases reported in students had been on the rise since 2008 (χ2trend=32.08, P<0.05). The main way of transmission was involved in homosexual transmission (2 525 cases, 63.54%), and homosexual transmission tended to rise since 2003 (χ2trend=79.43,P<0.05). The infection was generally identified in detection and consultation (1 832 cases, 46.10%) and clinical visit (1 628 cases, 40.97%). Joinpoint regression analysis showed that the reported cases of HIV infection in Hefei area were at average annual percent change (AAPC) by 21.90% per year (Z=13.44, P<0.05). Conclusion The HIV/AIDS prevalence in Hefei is relatively stable. Among them, middle aged and elderly population, students and men who have sex with men should be the key groups of HIV/AIDS prevention and control. Health education on AIDS prevention and control should be strengthened for this group of people, and AIDS screening should continue to be strengthened to achieve early detection, early diagnosis and early treatment.

    Journal of Tropical Diseases and Parasitology    2022, 20 (3): 149-157.  
    Abstract924)      PDF (1301KB)(3036)      
    Babesiosis is a zoonotic parasitic disease caused by Babesia infection. Babesia is transmitted through tick bites, blood transfusion or organ transplantation, and primarily parasitizes intracellularly in the erythrocytes of humans or other vertebrates. Babesia infecting humans mainly comprises Babesia microti, B. venatorum, B. duncani, B. divergens, etc. Babesiosis distributed worldwidely. This disease occurs more frequently in summer and autumn, yet is a new and rare parasitic disease in China, therefore many patients failed to receive timely treatment due to unavailable sensitive and effective methods for diagnosis of basesiosis in clinic in the past. However, with highly sensitive molecular biology detection techniques being clinically introduced, more cases of babesiosis were identified and reported. This paper reviewed the case reports of human babesiosis in China since 1943, summarized the research progress in diagnosis, treatment and pathogenesis of babesiosis, and analyzed the challenges and prospects for the prevention and control of babesiosis in China.
