Objective The aim of the study is to analyze the incidence patterns and epidemiological characteristics of parasitic and vector-borne diseases in the Minhang and Jinshan districts of Shanghai, and provide evidence-based information for optimizing prevention and control measures. Methods We collected information from epidemic reports and epidemiological investigation forms for cases of parasitic and vector-borne diseases from 2005 to 2024 in Shanghai's Minhang and Jinshan districts. Descriptive epidemiological method were adopted to conduct a comparative analysis of incidence trends, epidemic characteristics, and infection sources. Results A total of 229 cases in 7 categories were reported between 2005 and 2024, with an average annual incidence rate of 0.36/100 000. The average annual incidence rate in Minhang District was significantly higher than that in Jinshan District. The most prevalent diseases were malaria and dengue fever, followed by Japanese encephalitis. Monthly case reports were available, predominantly from June to October, with a peak in July-August. A statistically significant difference was observed between the two districts in case distribution during June-October (P<0.001), whereas no significant difference was found for July-August (P=0.331). The majority of cases were young men (111/229,48.47%), aged 20-39 years. Migrant workers/farmers constituted the largest occupational group (55/229, 24.02%). Registered residents of other provinces and cities (147/229,64.19%), and the main source of infection was overseas importation (112/229,48.91%). There were no statistically significant differences in gender and household-registration composition between the two districts (P>0.05). Significant differences existed in age, occupation, and source of infection (P<0.05). The imported diseases were malaria and dengue fever, with Africa and Southeast Asia being the primary source locations. Malaria was the predominant disease imported from other provinces and cities, with cases having been imported from abroad since 2012. Local infections were mainly Japanese encephalitis, followed by malaria (with the last local case reported in 2010). Cases between 2005 and 2009 were predominantly imported from other provinces and cities. The proportion of cases imported from abroad increased sharply after 2010, particularly in Minhang District. Local infections sometimes arise in Jinshan District, with Japanese encephalitis serving as the primary type. Conclusions Incidence rates of parasitic and vector-borne diseases in Minhang and Jinshan districts have generally remained low. To further reduce this disease burden, it will be necessary to strengthen joint measures for prevention and control, eliminate the environmental risk factors of vector organisms, enhance monitoring and precise control of the environment and inbound personnel to prevent the occurrence and transmission of parasitic and vector-borne diseases.

OBJECTIVE:
To investigate the effect of non-chemotherapy strategy of retinoic acid (ATRA) combined with arsenic trioxide (ATO) on the survival of patients with acute promyelocytic leukemia (APL).
METHODS:
The data of APL patients with complete information diagnosed in the hematology department of our hospital from June 2009 to November 2024 were retrospective analyzed. All patients in the non-CHT group received ATRA-ATO induction, consolidation and maintenance therapy. Patients in the CHT group received ATRA-ATO+chemotherapy induction therapy, followed by 3 cycles of ATRA-ATO+CHT consolidation therapy and 6-10 cycles of ATRA-ATO maintenance therapy. The primary endpoint was event-free survival (EFS). Secondary endpoints included overall survival (OS), remission rate, differentiation syndrome (DS) and safety.
RESULTS:
There were 182 patients with APL and 15 patients with early death (ED), accounting for 8.24%, which was related to age and risk stratification. There was no significant difference in remission rate between the non-CHT group and the CHT group (P =0.486). As of February 2025, the median follow-up time of patients was 39.5 months. The EFS of the non-CHT group was significantly better than that of the CHT group (P =0.038). There was no significant difference in OS between the two groups (P =0.442). Subgroup analysis showed that EFS in the non-CHT was longer in standard-risk patients (P =0.012). There was no significant difference in EFS (P =0.585) and OS (P =0.473) between the CHT and non-CHT groups in high-risk patients. The incidence of mild DS was 23.6% in the non-CHT group and 23.1% in the CHT group, respectively, with no statistically significant difference(P =0.937). Compared with CHT group, the incidence of serious adverse events was lower in the non-CHT group.
CONCLUSION
The non-chemotherapy regimen of ATRA combined with ATO is a feasible method to cure APL patients.

Kidney-Yang deficiency syndrome is a common geriatric disease that underlies chronic conditions such as diabetic nephropathy, chronic kidney disease, and osteoporosis. As age progresses, the kidney-Yang deficiency syndrome showcases increasingly pronounced manifestations, emerging as a key factor in the comorbidities experienced by elderly patients and affecting their quality of life and overall health status. Traditional Chinese medicine(TCM) has been extensively utilized in the treatment of kidney-Yang deficiency syndrome, with Epimedii Folium, Cinnamomi Cortex, and Lycii Fructus widely used in clinical settings. Despite the complexity of the molecular mechanisms involved in treating kidney-Yang deficiency syndrome, the potential therapeutic value of TCM remains compelling. Delving into the mechanisms of TCM treatment of kidney-Yang deficiency syndrome by regulating the neuro-endocrine-immune system can provide a scientific basis for targeted treatments of this syndrome and lay a foundation for the modernization of TCM. The pathophysiology of kidney-Yang deficiency syndrome involves multiple systems, including the interaction of the neuro-endocrine-immune system, the decline in renal function, the intensification of oxidative stress responses, and energy metabolism disorders. Understanding these mechanisms and their interrelationships can help untangle the etiology of kidney-Yang deficiency syndrome, aiding clinicians in making more precise diagnoses and treatments. Furthermore, the research on the specific applications of TCM in research on these pathological mechanisms can enhance the international recognition and status of TCM, enabling it to exert a greater global influence.

Objective To assess the status of rodent infestation in commercial kitchens using data from the‘Bright Kitchen, Clean Stove' initiative. The potential use of artificial-intelligence(AI)-based surveillance systems to monitor rodent density was explored, thereby providing a scientific basis for rodent control strategies. Methods As a component of the ‘Bright Kitchen, Clean Stove' initiative, the Minhang District Market Supervision Administration in Shanghai has installed cameras in 297 kitchens. These systems incorporate an AIpowered rodent image recognition method that automatically captures and stores the first image captured in each kitchen each day when a rodent is detected. In 2023, the system collected and stored 736 screenshots of rodents. Following manual verification,720 of the images were confirmed to contain rodents. The images were analyzed by noting the time, location, and kitchen area, and the species were manually identified to assess the population density. Results Rodent activity was detected in 34 of the 297 monitored kitchens, with an overall infestation rate of 11.45%. Of the 720 confirmed images of rodents, Rattus norvegicus(brown rat)was the predominant species, present in 409(56.81 %)images. Rodents were primarily concentrated in hot food preparation spaces. The density fluctuation curve had a multimodal pattern peaking in spring and autumn. The peak of daily activity was between 22: 00 and 2: 00. There was a significant difference in the rodent detection frequency between weekends and weekdays during peak hours and during non-peak hours(χ2=7.18, P< 0.01). Conclusions The ‘Bright Kitchen, Clear Stove' smart monitoring system has been proven to be applicable to rodent density monitoring. To control rodents in commercial kitchens, greater efforts are required to address and identify the specific infesting conditions and the key points in the control process.

Objective To investigate the efficacy of histone deacetylase(HDAC)inhibitor chidamide combined with the PD-1 inhibitor on CD8+ T cells anti-cancer function in OVA-expressing MC38(MC38-OVA)colorectal-bearing mice.Methods Animal experiments:C57BL/6 tumor models were constructed by subcutaneously injecting MC38-OVA colorectal cancer cells into the back of mice.We randomized mice into control group,chidamide group,anti-PD-1 group and chidamide+anti-PD-1 group(20 each group).We monitored the tumor growth and animal survival rate of each group;we employed a flow-based method to detect the number and ratio of tumor-infiltrating CD8+ T cells,CD8+IFN-γ+ T cells,OVA antigen-specific CD8+ T cells,and the expression changes of regulatory T cells(Treg),myeloid-derived suppressor cells(MDSC),and tumor-associated macrophages(TAM).Cell experiments:We used a flow-based method to detect the apoptosis of CD8+ T cells and MC38-OVA tumor cells after 0,10,25,50,100,or 200 nmol/L chidamide treatment.The proliferation of CD8+ T cells and MC38-OVA tumor cells treated with 0 and 100 nmol/L chidamide was detected by Ki-67 antibody labeling and cell counting.To evaluate CD8+ T cell killing ability,we treated CD8+ T cells with various conditions(control group,chidamide group,anti-PD-1 group and chidamide+anti-PD-1 group)followed by co-culture with MC38-OVA tumor cells,using the flow-based method.In the condition that CD8+ T cells treated with 0 and 100 nmol/L chidamide co-cultured with the same number of MC38-OVA tumor cells,the expression of CD107a was detected by flow cytometry.Results Compared with control group,the tumor growth was inhibited(P<0.05)while the survival rate was improved(P<0.01)in chidamide+anti-PD-1 group.The number of tumor-infiltrating CD8+ T cells was significantly higher in chidamide group,anti-PD-1 group and chidamide+anti-PD-1 group than that in control group(P<0.05).Nonetheless,the ratio and levels of CD8+IFN-γ+ and OVA antigen-specific CD8+ T cells were significantly higher in chidamide+anti-PD-1 group than those in other groups(P<0.05).The in vitro experiment results showed that chidamide could enhance the killing ability of CD8+ T cells and the expression of CD107a.Conclusion Chidamide combined with PD-1 inhibitor significantly enhanced the number and function of tumor-infiltrating CD8+ T cells and increased antigen-specific CD8+ T cells,which will provide a theoretical and experimental basis for the combination of chidamide in clinical solid tumor immunotherapy.
