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 analyze inpatients preferences for an unaccompanied ward and its influencing factors, for references for the implementation of unaccompanied ward management.Methods:Based on a convergent mixed research design, a convenience sampling method was used to select inpatients who visited a tertiary hospital from June to August 2024 as the survey subjects. A questionnaire survey was conducted on their willingness to choose the unaccompanied ward (provided by medical nursing staff). Meanwhile, using purposive sampling method, 10 inpatients and 11 accompanying family members were selected for semi-structured interviews about unaccompanied ward prference, and the interview topics were summarized and extracted. The results of quantitative and qualitative were compared and integrated.Results:The quantitative research results showed that among the 805 inpatients included, 125 patients (13.03%) chose medical caregivers, 382 patients (39.83%) chose their spouses, and 272 patients (28.36%) chose their children; 411 patients (24.54%) did not choose medical caregivers due to financial burden; 509 patients (63.23%) believed that the cost of an unaccompanied ward should be less than 120 yuan/day. The qualitative research results showed that the interview data formed three themes, including the driving factors of caregiving form selection intention, the emotional tendency of caregiving form selection intention, and the assessment of the benefits and drawbacks of caregiving form selection intention. The mixed research results showed that the majority of inpatients choose their spouse or children accompany them, and their willingness to choose medical caregivers is mainly influenced by service costs and family labor. However, its did not affect patients who are young or have difficulty caring for them; Influenced by traditional Chinese culture, patients tended to choose relatives to accompany them; The main reasons why patients did not choose unaccompanied wards were the economic burden and the mismatch between medical nursing staff services and their expectations.Conclusions:Inpatients tended to choose family members to accompany them. Their willingness to choose unaccompanied ward was influenced by economic burden, family labor, patient age, caregiving difficulty, and filial piety culture.

OBJECTIVE:
To retrospectively analyze the clinical characteristics of 15 children with B-cell acute lymphoblastic leukemia (B-ALL) treated with blinatumomab, and summarize the efficacy and safety of blinatumomab in the treatment of pediatric B-ALL.
METHODS:
Fifteen children who received treatment with blinatumomab from February 2022 to January 2023 were enrolled in this study. One course (28 days) of blinatumomab concurrent with intrathecal chemotherapy was given according to the standard regimen, except for 2 cases who had shortened course of treatment due to hematopoietic stem cell transplantation (HSCT) and did not receive combined intrathecal chemotherapy, and 1 case had a shortened course of treatment due to economic problems. The efficacy and safety of the treatment were evaluated.
RESULTS:
In terms of efficacy, for the children who had achieved complete molecular remission (CMR) before treatment, blinatumomab treatment could effectively maintain CMR status; For the children who did not achieve CMR, the CMR rate after one standard course of treatment with blinatumomab reached 66.7%(4/6); For the children with relapsed/refractory ALL (R/R ALL) who had minimal residual disease (MRD), the MRD clearance rate reached 75.0%(3/4). The statistical results of the incidence of adverse events showed that 13.3%(2/15) of the children did not experience any adverse events. The most common adverse events were cytokine release syndrome (CRS) (73.3%, 11/15) and transaminase elevation (26.7%, 4/15); 33.3%(5/15) of the children experienced grade 3 or higher adverse events. All the adverse events were resolved after symptomatic treatment.The level of IgG decreased significantly after 4-7 weeks of treatment with blinatumomab, and gradually recovered after 8 weeks of treatment.
CONCLUSION
Blinatumomab can be used as a safe and effective treatment for inducing deep remission in pediatric R/R-ALL patients and as a bridge therapy for the pediatric ALL patients who are intolerant to chemotherapy.

As a novel form of cell death, ferroptosis is mainly regulated by the accumulation of soluble iron ions in the cytoplasm and the production of lipid peroxides and is closely associated with several diseases, including acute kidney injury, ischemic reperfusion injury, neurodegenerative diseases, and cancer. The term "immunosuppression" refers to various factors that can directly harm immune cells' structure and function and affect the synthesis, release, and biological activity of immune molecules, leading to the insufficient response of the immune system to antigen production, failure to successfully resist the invasion of foreign pathogens, and even organ damage and metabolic disorders. An immunosuppressive phase commonly occurs in the progression of many ferroptosis-related diseases, and ferroptosis can directly inhibit immune cell function. However, the relationship between ferroptosis and immunosuppression has not yet been published due to their complicated interactions in various diseases. Therefore, this review deeply discusses the contribution of ferroptosis to immunosuppression in specific cases. In addition to offering new therapeutic targets for ferroptosis-related diseases, the findings will help clarify the issues on how ferroptosis contributes to immunosuppression.

Objective This study aimed to investigate the correlation of cerebral perfusion and cognitive function status in patients with minor stroke(MS)or transient ischemic attack(TIA)complicated by severe intracranial arterial stenosis or occlusion(hereafter referred to as ICAS-MSTIA).Methods Retrospectively enrol consecutive ICAS-MSTIA patients admitted to the Department of Neurology,the First Affiliated Hospital of Xi'an Jiaotong University,from June 2023 to May 2024.In the meantime,healthy controls were openly recruited.The ICAS-MSTIA patients were divided into two groups based on the side of intracranial large artery stenosis or occlusion:the left intracranial large artery involvement group and the right intracranial large artery involvement group.All patients with intracranial large artery stenosis or occlusion underwent MR scanning within 2 weeks after the first episode of TIA or MS,while there was no specific time requirement for MR examination in the healthy control group.On the day of MR scanning,the Montreal cognitive assessment(MoCA)scale was used to evaluate the participants'global cognitive function and performance in various cognitive domains,including visuospatial/executive function,naming,attention,language,abstraction,delayed recall,and orientation.General information of all participants was collected,including age,sex,educational level,body mass index,and history of smoking and alcohol consumption.Clinical data were collected from both left and right intracranial large artery involvement groups,including cerebrovascular risk factors(such as,diabetes mellitus,hypertension,and hyperlipidemia),National Institutes of Health stroke scale(NIHSS)score at admission,responsible stenotic or occluded arteries(internal carotid artery,middle cerebral artery),degree of stenosis in the responsible vessel(severe stenosis[stenosis rate 70%-99%],occlusion[stenosis rate100%])and non-responsible vessel(no stenosis[0],mild stenosis[stenosis rate>0-49%]),collateral circulation compensation(American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology[ASTIN/SIR]collateral circulation classification),and responsible events(TIA,MS).General data and MoCA scale scores were compared across the three groups,while clinical data were compared between the left and right intracranial large artery involvement groups.Statistical parametric mapping 12(SPM 12)was used to perform voxel-wise independent samples t-tests on cerebral blood flow(CBF)differences among the left ICAS-MSTIA group,right ICAS-MSTIA group,and healthy control group,with cluster-level family-wise error(FWE)correction applied for adjustment.Multiple linear regression analysis was conducted to evaluate the relationship between global CBF values and total MoCA scores in ICAS-MSTIA patients with left or right intracranial large artery involvement.Results A total of 33 ICAS-MSTIA patients and 33 healthy controls were enrolled in the study.Among the ICAS-MSTIA patients,21 had left intracranial large artery involvement and 12 had right involvement.(1)Among the three groups,statistically significant differences were observed in the proportions of individuals with reported smoking history(P=0.024)and alcohol consumption history(P=0.011).The left intracranial large artery involvement group had a higher NIHSS score(0[0,2]vs.0[0,0],P=0.044)and a higher proportion of patients with internal carotid artery involvement(13/21 cases vs.2/12 cases,P=0.027)compared with the right side group.No statistically significant differences were observed in other general or clinical data across the three groups or between the two non-control groups(all P>0.05).(2)Statistically significant differences were found across the three groups in the MoCA scale total score and scores of visuospatial/executive function,attention,language,abstraction,delayed recall,and orientation cognitive domains(all P<0.05),while no significant difference was noted in the naming score(P=0.063).The left intracranial large artery involvement group had lower total MoCA score and lower scores in visuospatial/executive function,attention,language,abstraction,delayed recall,and orientation in comparison to the healthy control group(all P<0.016 7).The right intracranial large artery involvement group had significantly lower scores in language,abstraction,and orientation domains than the healthy control group(all P<0.016 7).Additionally,the left side group had a lower attention domain score than the right side group(P<0.016 7).No other statistically significant differences were found in pairwise comparisons(all P>0.016 7).(3)Patients in both the left and right intracranial large artery involvement groups exhibited a significant decrease in CBF in extensive regions on the affected side,including the temporal lobe,dorsolateral prefrontal cortex,and occipital lobe.Furthermore,after correction,in the left involvement group CBF was higher in the contralateral lingual gyrus,cuneus,and calcarine sulcus compared with the healthy control group(P<0.05).While in the right involvement group,no regions had increased CBF compared to the healthy control group.(4)Multiple linear regression showed positive correlation between CBF in ipsilateral precentral gyrus and superior temporal gyrus,and the total MoCA score in patients with left intracranial large artery involvement(FWE-corrected,P<0.05).In contrast,there was no correlation between CBF and total MoCA score in patients with right intracranial large artery involvement.Conclusions ICAS-MSTIA patients exhibited various degrees of impairment in cerebral perfusion and cognitive function.A significant positive correlation is observed between these two impairments in patients with left intracranial large artery involvement.

Ischemic stroke is a disease resulting from the cerebral ischemia and hypoxia caused by the blockage of brain vessels in the brain,and is characterized by the focal neurological signs.Pathologically,neuronal necrosis in the infarcted area and the neuronal degeneration or delayed death of neurons in the ischemic penumbra,contribute to the morphological basis of the disease.Ischemic stroke is regulated by multiple processes,including ferroptosis,apoptosis,and autophagy.Ferroptosis,a type of iron-dependent cell death,is closely associated with ischemic stroke.Nuclear factor erythroid 2-related factor 2(Nrf2),a key transcription factor,plays a critical role in maintaining cellular redox balance and regulating inflammatory responses.Nrf2 promotes the expression of solute carrier family 7 member 11(SLC7A11)and glutathione peroxidase 4(GPX4),thereby activating the Nrf2 signaling pathway to counteract ferroptosis and protect cells from damage.This article reviews and analyzes recent experimental studies on traditional Chinese medicine(TCM)therapy targeting the Nrf2/SLC7A11/GPX4 pathway to suppress ferroptosis.The studies have found that TCM therapy with herbal compounds,Chinese patent medicines,single herbal components and their active ingredients,and acupuncture and moxibustion can inhibit ferroptosis by activating the Nrf2/SLC7A11/GPX4 signaling pathway,which will provide novel strategies for the TCM intervention of ischemic stroke.

Objective To investigate the efficacy of acupuncture therapy combined with acupoint patching in alleviating chronic pelvic pain,a sequela of pelvic inflammatory disease(SPID-CPP).Methods A total of 120 SPID-CPP patients attending our hospital between January 2022 and November 2024 were enrolled and randomly assigned to either an experimental group or a control group,with 60 patients in each group.Both groups received conventional lifestyle guidance and anti-infection therapy.The control group received only acupuncture therapy,while the observation group received acupuncture combined with acupoint patching therapy.The duration of treatment was identical for both groups.The treatment effect,levels of high-sensitivity C-reactive protein(hs-CRP),white blood cell count(WBC),neutrophil percentage(NEUT),fibrinogen(FIB)level,quality-of-life scores,and visual analog scale(VAS)pain scores were compared between the experimental and control groups.Results The treatment efficacy rate of the experimental group was 93.00%,while that of the control group was only 73.33%,and the difference between the two groups was statistically significant(P<0.05).Following therapy,the hs-CRP,WBC,NEUT,and VAS ratings of both the control and experimental groups decreased.Furthermore,findings of the experimental group were significantly lower than those of the control group(P<0.05).The quality-of-life score of the experimental group was higher than that of the control group(P<0.05).Conclusion Acupuncture combined with acupoint patching demonstrates significant efficacy in treating SPID-CPP.This combined therapy effectively reduces pain in SPID-CPP patients,decreases serum levels of inflammatory factors,and significantly improves patients'quality of life.

Objective By observing and measuring the relevant data of the buccal branch of the facial nerve,the parotid duct and the facial artery,the positional relationship among the three was analyzed to avoid accidental injury to the buccal branch of the facial nerve and the parotid duct when ligaturing the facial artery during the operation.Methods Forty adult head and neck specimens were dissected to observe the relationship between the buccal branch of the facial nerve and the parotid duct,the course and positional relationship of the facial artery,and the relationship between the buccal branch of the facial nerve and the peripheral vascular network.The relevant diameters were measured with a vernier caliper.Results The buccal branch of the facial nerve was divided into the superior buccal branch and the inferior buccal branch,and there was no direct anastomosis or connecting fiber between the buccal branch of the facial nerve and the parotid duct.The superior buccal branch was relatively thick,and it has a relatively constant position,which was parallel to the parotid duct.The position of the inferior buccal branch was not constant and it ran on or slightly above the plane of angulus oris.The superior buccal branch was located(10.76±5.54)mm from the parotid duct,while the inferior buccal branch was positioned(6.84±4.06)mm away from the parotid duct.The course of the main trunk of the facial artery was relatively fixed.Moreover,if the branch of the facial artery was missing,other branches of the facial artery would extend to replace the missing branch artery.The main trunk of the facial artery had a diameter of(2.34±0.83)mm,and its branches formed anastomoses with the buccal branch of the maxillary artery,creating a vascular network in the parotid and buccal regions.There was a vascular network around the buccal branch of the facial nerve,which was mostly small branches of the facial artery and the superficial temporal artery.Conclusion The buccal branch of the facial nerve exhibits a consistent anatomic relationship with the parotid duct and the facial artery.During the ligation of the facial artery,the parotid duct can serve as a landmark to accurately locate the buccal branch of the facial nerve,thereby significantly reducing the risk of inadvertent injury to the buccal branch of the facial nerve and the parotid duct.
