Objective To provide a scientific basis for vector prevention and control in port areas, vector monitoring has been conducted continuously to characterize the composition, density, and seasonal fluctuations of vectors across 21 port-areas of Shandong province from 2017 to 2023. Methods In accordance with the Regional Vector Monitoring Plan for Frontier Ports, vector surveillance of mosquitoes, flies, cockroaches, rodents, and other disease vectors was performed. Data were analyzed to describe vector community composition and identify seasonal fluctuations. Results A total of 601 rodents belonging to 1 family, 4 genera, and 4 species were captured. Three dominant rodent species inhabit port areas. In addition, 88 104 mosquitoes were captured and classified into 3 subfamilies, 4 genera, and 12 species; 38 959 flies were trapped and classified into 8 families,31 genera, and 51 species, including 9 dominant fly species in port-areas; and 54 672 captured cockroaches were classified into 2 families,4 genera, and 4 species, with Blattella germanica as the dominant species. Conclusions Significant vector community changes(P＜0.005)have been identified after the epidemic. To improve the pertinence and efficacy of port health quarantine work, continuous and strong attention should be paid to vector compositions and population densities at Shandong ports.

Objective To compare and analyze malaria epidemic trends and characteristics of initial confirmed cases before and after malaria eliminating in Qingjiangpu District, Huai&prime;an City, and to provide a scientific basis for improving strategies to prevent imported malaria retransmission. Methods Malaria case data from Qingjiangpu District were obtained from the National Infectious Disease Information Reporting System for 2010-2023. Case investigation and epidemiological data were summarized and analyzed for the pre-elimination period (2010-2016)and post-elimination period(2017-2023). Results A total of 185 malaria cases were reported between 2010 and 2023, with one locally acquired case in both 2010 and 2011; the remainder were imported, primarily falciparum malaria. Post-elimination cases decreased from 140 to 45, showing a statistically significant difference in case distribution ratios(χ2=9.642, P<0.05). Seasonal peaks occurred in early January and mid-July before elimination but showed no distinct pattern afterward. Malaria cases were mainly imported from Africa countries, and most patients were young adult males. Post-elimination, the proportion of migrant workers decreased, while technical and business personnel increased significantly(χ2=17.855, P<0.05). Both time-to-diagnosis and time-to-certification changed markedly after elimination, with township health centers showing improved diagnostic accuracy at initial visits. All confirmed patients were treated at designated municipal medical institutions. Conclusions After malaria elimination in Qingjiangpu District, imported malaria remains a serious concern, with cases reported each year. Therefore, it is necessary to continue strengthening the malaria monitoring system, enhance screening and evaluation of key populations, improve health education, raise diagnostic and treatment capacity across all medical institutions, and consolidate the achievements of malaria elimination.

Objective To investigate the epidemiological characteristics and changing trend of typhus in Shaanxi Province from 2005 to 2023 to provide a scientific basis for its prevention and control. Methods Excel 2007, SPSS 25.0, Joinpoint 4.9.1.0, and Geoda 1.6 were used for data collection and statistical analysis. Super Map was used for data visualization to describe the changing characteristics of the disease. Results A total of 394 typhus cases were reported in Shaanxi Province from 2005 to 2023. The average annual incidence of typhus was 0.054/100 000, showing a dynamic fluctuation trend(AAPC=-3.3, t=-0.3, P>0.05). The cases were mainly concentrated in Baoji, Hanzhong and Xi&prime;an, accounting for 78.68%. The incidence peak was from May to October, accounting for 64.21% of annual incidence. The epidemic season was from May to October and December. The incidence of the disease was concentrated in the 40-69 age group, accounting for 58.88%, and the sex was 1.07:1. The main occupation was farmers, accounting for 72.08%. The median time from onset to diagnosis was 7 days. Global spatial autocorrelation analysis showed that there were significant spatial autocorrelations in 11 years from 2005 to 2023(P<0.05). Local spatial autocorrelation analysis detected a total of 43“high-high”clustering areas, mainly concentrated in Baoji City. Conclusions The overall incidence of typhus in Shaanxi Province showed a dynamic fluctuation trend, with notable seasonal and regional aggregation. The incidence of typhus was higher in middle-aged and elderly people in rural areas. Surveillance should be strengthened in typhus endemic areas in summer and autumn, and health education should be conducted for key population to form good health habits and reduce the incidence of typhus.

Objective This study reports on the obligatory parasitism of water mites Arrenurus sp. on Anopheles messeae at the Manzhouli Port, Inner Mongolia, China. Methods Duing July 2024, a survey on the mosquito diversity was conducted at the Manzhouli Port. Captured mosquitoes and their ectoparasites were identified to species level. Results A total of 1840 adult mosquitoes were collected, representing species from three genera: Culex(Cx. modestus, Cx. pipiens pallens), Aedes(Ae. dorsalis, Ae. flavidorsalis, Ae. flavescens), and Anopheles (An. messeae). Among all the mosqutioes specimens,3 out of 150 captured An. messeae were found to carry ectoparasitic mites, with number of 2,4,27 mites separately. Morphological and molecular identification reached the same result as water mites(Hydrachnidiae, Hydracrina). COI gene sequence showed 94% similarity with the closest species Arrenurus truncatellus. Conlusions Literature review suggests water mites are host-specific parasitism of mosquito species and herein with the first record of Arrenurus sp. parasiting on An.

We report a case of a female farmer from the Yichang suburb, aged 68 years, who had been suffering from the infection for 3 years and had a history of seeking medical treatment at a community hospital and receiving blood transfusions. Her hemoglobin was as low as 28 g/L during this visit, and she had been ill for a long time with severe anemia. Routine stool examination revealed hookworm eggs. After active treatment, the patient recovered and was discharged from the hospital.

Autism spectrum disorder in children (hereinafter called "childhood autism") is a prevalent neurodevelopmental condition; however, ancient Chinese medical texts did not provide detailed accounts of it. The concept of "the sovereign fire illuminates, while the ministerial fire occupies its position" was first introduced in the Plain Questions: The Great Treatise on the Origin of Heavenly Influences chapter. Subsequent medical practitioners have elaborated on this idea, identifying the sovereign fire as the master of the spirit and governing life activities, while the ministerial fire is the assisting minister that supports the functions of the zang-fu organs. When these two are in harmony, they complement each other, collectively sustaining the body&prime;s normal physiological functions. In the context of this theory, the pathogenesis of childhood autism is attributed to the imbalance between the sovereign and ministerial fires. The root cause lies in the mutual antagonism of these two fires, resulting in the dysfunction of the spirit. Central to childhood autism onset is the dimming of the sovereign fire and a deficiency in the spirit, while the displacement of the ministerial fire and the impaired function of the five viscera contribute significantly to the progression of the condition. Effective treatment for childhood autism involves restoring these imbalances: dispelling yin-related obstructions to illuminate the sovereign fire, nourishing the spleen and kidney to nourish the ministerial fire, and regulating the liver and lung to harmonize the sovereign and ministerial fires. The ultimate goal is to integrate body and spirit, harmonize the sovereign and ministerial fires, and restore the interconnectedness between spirit and the function of the five zang viscera. This article, based on the "the sovereign fire illuminates, while the ministerial fire occupies its position" theory, provides a novel perspective and insights for understanding and treating childhood autism through the holistic principles of traditional Chinese medicine. Emphasizing the integration of body and spirit offers new insights and approaches for the clinical management of childhood autism in traditional Chinese medicine.

The lung collaterals form a network that branches from the lung meridian, traversing the lung system and extending across the body&prime;s surface. Lung collateral disease refers to the structural alterations or dysfunction in these collaterals caused by external or internal pathogens. Research into the structural and physiological functions of children&prime;s lung collaterals, as well as the pathogenesis and syndrome differentiation for treating lung collateral diseases in children, holds significant value in guiding the prevention and treatment of pediatric respiratory conditions. Drawing on the theory of collateral disease, the clinical insights of both historical and contemporary physicians, and modern research findings—while considering the unique physiological and pathological characteristics of children&prime;s respiratory systems—this study provides a foundational summary of the morphology and spatial distribution of children&prime;s lung collaterals. The characteristics of these collaterals are highlighted as thin, sparse, short, narrow, brittle, and tender. From this structural understanding, the unique physiological functions of children&prime;s lung collaterals are analyzed. The study further explores the interactions between pathogenic factors and lung collaterals, elucidating the pathogenesis and progression of children&prime;s lung collateral diseases. It proposes treatment principles centered on "seeking treatment in the collaterals and employing the method of unblocking collaterals, "which align with the unique features of pediatric lung collaterals. Common treatment approaches, and relevant prescriptions for managing these diseases are summarized. This paper lays the foundation for a theoretical system encompassing the structure, function, pathogenesis, and syndrome differentiation for treating children&prime;s lung collateral diseases. It offers valuable insights for the clinical diagnosis and management of pediatric respiratory diseases linked to collateral dysfunction and serves as a reference for the systematic development of a broader theoretical framework for children&prime;s collateral diseases.

Multiple system atrophy (MSA) is a rare neurodegenerative disease with complex clinical manifestations, presenting substantial challenges in clinical diagnosis and treatment. Its symptoms and the eight extraordinary meridians are potentially correlated; therefore, this article explores the association between MSA symptom clusters and the eight extraordinary meridians based on their circulation and physiological functions, as well as their treatment strategies. The progression from deficiency to damage in the eight extraordinary meridians aligns with the core pathogenesis of MSA, which is characterized by "the continuous accumulation of impacts from the vital qi deficiency leading to eventual damage". Liver and kidney deficiency and the emptiness of the eight extraordinary meridians are required for the onset of MSA; the stagnation of qi deficiency and the gradual damage to the eight extraordinary meridians are the key stages in the prolonged progression of MSA. The disease often begins with the involvement of the yin and yang qiao mai, governor vessel, thoroughfare vessel, and conception vessel before progressing to multiple meridian involvements, ultimately affecting all eight extraordinary meridians simultaneously. The treatment approach emphasizes that "the direct method may be used for joining battle, but indirect method will be needed in order to secure victory" and focuses on "eliminate pathogenic factors and reinforce healthy qi". Distinguishing the extraordinary meridians and focusing on the primary symptoms are pivotal to improving efficacy. Clinical treatment is aimed at the target, and tailored treatment based on careful clinical observation ensures precision in targeting the disease using the eight extraordinary meridians as the framework and core symptoms as the specific focus. Additionally, combining acupuncture, daoyin therapy, and other method may help prolong survival. This article classifies clinical manifestations based on the theory of the eight extraordinary meridians and explores treatment.
