Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Objective:To analyze the epidemiological and clinical characteristics of respiratory syncytial virus (RSV) infection in children in Jiangsu Province from 2014 to 2023.Methods:The acute respiratory infection cases in children aged 0-14 years were selected from outpatient/emergency or inpatient departments in 2 surveillance sentinel hospitals, respectively, in Nanjing, Suzhou and Taizhou of Jiangsu from 1 July 2014 to 31 December 2023, and RSV nucleic acid test was conducted and the intensity of the RSV infection was accessed by WHO influenza epidemiological threshold method, and case information and clinical data were collected. χ2 test was used to compare the differences between groups, and the Bonferroni method was used for pairwise comparisons between groups. Results:In 4 946 cases of acute respiratory infections, the RSV positive rate was 8.21% (406/4 946), and the age M( Q1, Q3) of the cases was 1 (0, 3) years. The RSV positive rate was 10.92% (258/2 362) during 2014-2019 and 6.06% (118/1 948) during 2019-2023, the difference was significant ( χ2=31.74, P<0.001). RSV infection mainly occurred from October to March during 2014-2019, with the incidence peak in December and moderate or higher intensity. The seasonality of RSV infection was not obvious during 2019-2023, with low intensity. The RSV positive rate was highest in children in age group 0- years (17.85%, 151/846), and the positive rate declined gradually with age ( χ2=184.51, P<0.001). The RSV positive rate was higher in inpatient cases (9.84%, 244/2 480) than in outpatient/emergency cases (6.57%, 162/2 466) ( χ2=17.54, P<0.001). In the 155 RSV infection cases with complete clinical data, the clinical symptoms mainly included cough (99.35%, 154/155), fever (55.48%, 86/155), and shortness of breath (45.16%, 70/155). In the cases aged <6 months, the proportion of those with fever was low, but the proportion of those with shortness of breath, transferred to intensive care units, and receiving oxygen therapy were higher (all P<0.05). Children aged <6 months and those with underlying diseases were more likely to have severe RSV infection (all P<0.05). Conclusions:RSV infection in children in Jiangsu Province showed seasonal prevalence in winter from 2014 to 2019. Since 2020, the seasonal characteristics of the epidemic have changed, the epidemic period has been dispersed and the epidemic intensity has decreased. Infants <1 year old were at high risk for RSV infection, and those <6 months old and with underlying diseases might have severe infection.

Objective To systematically evaluate the experiences of drug self-management in elderly patients with multiple chronic illnesses,so as to provide references for the development of personalized drug self-management intervention programs.Methods Qualitative research on drug self-management experiences of elderly patients with multiple chronic diseases was retrieved from PubMed,Cochrane Library,Embase,CINAHL,Web of Science,Scopus,CNKI,Wanfang,VIP and SinoMed.The retrieval time limit is from the establishment of the databases to November 2023.The qualitative research quality evaluation criteria of the Joanna Briggs Institute Evidence-based Health Care Center in Australia was used to evaluate quality of studies.The results were integrated by meta-integration method.Results A total of 9 studies were included,and 33 research results were extracted,and 4 integrated results and 12 categories were synthesized.The integration results included the objective dilemmas and challenges of drug self-management,the low level of drug literacy,willingness to engage in positive behavior attempts,need of multi-party assistance.Conclusion The objective dilemmas of drug self-management and low level of drug literacy in elderly patients with multimorbidity will seriously affect their health outcomes.Medical staffs should pay attention to the different experiences of patients in the process of drug self-management,identify the needs of patients,formulate targeted intervention support strategies,and improve the level of drug self-management in elderly patients.

Objective:To investigate the clinical value of ultrasound-guided thoracic paravertebral block (TPVB) combined with bronchial blocker (BB) placement in thoracoscopic surgery.Methods:A randomized controlled study was conducted involving 60 patients scheduled for thoracoscopic surgery at The First Affiliated Hospital of Xiamen University from November to December 2023. These patients were classified as American Society of Anesthesiologists (ASA) I-II. They were divided into an observation group (BB placement) and a control group (double-lumen bronchial blocker placement) using the random number table method, with 30 patients in each group. Preoperatively, TPVB was performed under ultrasound guidance. After the induction of general anesthesia, a single-lumen tracheal tube was inserted, followed by the placement of a BB in the observation group, while a corresponding type of double-lumen bronchial tube was inserted in the control group. A fiberoptic bronchoscope was used for positioning and fixation in both groups, and anesthesia was maintained with intravenous anesthesia. The following parameters were assessed in each group: positioning time for intubation; number of cases with tube displacement; number of cases of postoperative pharyngeal pain; hemodynamic parameters [mean arterial pressure (MAP) and heart rate (HR)] before and after intubation; and blood gas analysis [partial pressure of oxygen (PaO 2) and carbon dioxide (PaCO 2)]. Additionally, the surgical field exposure score and the dosages of propofol and remifentanil administered during surgery were recorded. Levels of inflammatory markers [interleukin (IL)-2, IL-4, IL-6, IL-10, tumor necrosis factor (TNF) -α, and TNF-β] and Visual Analog Scale scores for pain at rest and during cough, recorded at 2, 4, 8, 10, 12, and 24 hours postoperatively were compared between the two groups. Results:The total amounts of propofol [(569.7 ± 29.2) mg] and remifentanil [(289.3 ± 46.3) μg] in the observation group were significantly lower than those in the control group [(612.6 ± 28.7) mg, (361.7 ± 40.6) μg, t = 5.74, 6.44, both P = 0.001]. The recovery time in the observation group [(31.8 ± 11.4) minutes] was significantly shorter than that in the control group [(37.5 ± 10.1) minutes, t = 2.10, P = 0.040]. There was no significant difference in positioning time for intubation between observation and control groups [(67 ± 13) seconds vs. (80 ± 36) seconds, t = 1.86, P = 0.068). There was no significant difference in percentage of cases who underwent tube displacement after intubation between observation and control group [23.3% (7/30) vs. 16.7% (5/30), χ2 = 0.58, P = 0.445]. The incidence of postoperative pharyngeal pain in the observation group was significantly lower than that in the control group [10.0% (3/30) vs. 33.3% (10/30), χ2 = 5.02, P = 0.025). There were no statistically significant differences between the two groups in terms of number of cases with tube displacement, hemodynamic parameters, blood gas analysis, inflammatory markers, surgical field exposure, and postoperative Visual Analog Scale scores between the two groups (all P > 0.05). Conclusion:Ultrasound-guided TPVB combined with BB placement during thoracoscopic surgery can reduce airway injury compared with the use of a double-lumen bronchial tube. It provides adequate sedation and analgesia during the procedure, facilitates rapid awakening, promotes early recovery of spontaneous breathing, and has fewer adverse reactions, making it worthy of clinical promotion.

Objective:To explore the real experience and needs of successful aging among urban elderly people who participated in intergenerational raising.Methods:This study was a qualitative study. From February to April 2023, purposive sampling was used to select 10 elderly individuals from Fanjingjiayuan Community in Changqing District, Jinan City who participated in intergenerational raising as the research subject. Semi-structured interviews and face-to-face nonverbal behavior observation methods were used to collect data, while Colaizzi's 7-step analysis method was used to summarize, analyze the data and extract themes.Results:A total of three themes and 10 sub-themes were extracted, namely positive psychological feelings (self-realization, obtaining emotional support, health benefits), negative psychological feelings (intergenerational raising pressure, decreased life satisfaction, mental stress, physical and mental exhaustion), and the need to promote successful aging (family support, community support, policy support) .Conclusions:Urban elderly people who participate in intergenerational raising have both negative and positive psychological experiences. Families and society should pay attention to the psychological feelings of participating in intergenerational raising of elderly people in urban communities, so as to promote successful aging of the elderly people.

Microglial surveillance plays an essential role in clearing misfolded proteins such as amyloid-beta, tau, and α-synuclein aggregates in neurodegenerative diseases. However, due to the complex structure and ambiguous pathogenic species of the misfolded proteins, a universal approach to remove the misfolded proteins remains unavailable. Here, we found that a polyphenol, α-mangostin, reprogrammed metabolism in the disease-associated microglia through shifting glycolysis to oxidative phosphorylation, which holistically rejuvenated microglial surveillance capacity to enhance microglial phagocytosis and autophagy-mediated degradation of multiple misfolded proteins. Nanoformulation of α-mangostin efficiently delivered α-mangostin to microglia, relieved the reactive status and rejuvenated the misfolded-proteins clearance capacity of microglia, which thus impressively relieved the neuropathological changes in both Alzheimer's disease and Parkinson's disease model mice. These findings provide direct evidences for the concept of rejuvenating microglial surveillance of multiple misfolded proteins through metabolic reprogramming, and demonstrate nanoformulated α-mangostin as a potential and universal therapy against neurodegenerative diseases.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Retrohepatic inferior vena cava (RIVC) begins at the base of renal vein and ends at the right atrium. Left, middle, right hepatic vein, inferior right hepatic vein etc. run into it. The major part of RIVC is wrapped in the caudate lobe of liver. It is adjacent to the abdominal trunk and vertebral body, having important anatomical significance. Inferior vena cava tumor thrombus includes two types. One is tumor thrombus formations in the RIVC. The other is direct invasion of tumor into RIVC wall. These two types correspond to different surgical treatment methods. The cancer thrombus in the vena cava can be treated by thrombus removal, while the tumor invading the vena cava wall requires resection of the invaded vascular wall and vascular reconstruction. Regardless of the types, improper surgical treatment is easy to cause injury and bleeding, leading to severe consequences. In this article, the main points of surgical management of different types of cancer thrombus in RIVC are introduced, providing methods to handle them.

Objective:To understand the relationship between the RNA shedding time of SARS-CoV-2 infected persons and the single nucleotide mutation of the virus, the population of infected persons, underlying diseases and other factors, so as to provide more clues for the study of SARS-CoV-2 infection dynamics.Methods:The data of epidemiology, clinical manifestations, and underlying diseases of infected persons in a cluster epidemic of COVID-19 in Jiangsu province from July to September 2021 were collected. Nasopharyngeal swab samples of cases were collected, and the whole genome of the virus was sequenced by second-generation sequencing technology. The online analysis platform was used to judge the virus type and analyze the mutation site, and Cox proportional risk model was used to analyze the relationship between the RNA shedding time of SARS-CoV-2 and various research factors.Results:There were 350 persons who finally obtained the whole genome sequence of the virus in this COVID-19 outbreak, of which 60.3% were female, the median age was 49 years old (interquartile range, IQR: 37-65 years old)), and the median time of virus shedding was 33 days ( IQR, 26-44 days). The whole-genome sequencing analysis showed that compared with the Wuhan reference strain sequence, the infected persons’ sequence had 34~41 nucleotide mutation sites, belonging to VOC/Delta variant (B.1.617.2 evolutionary branch), and C346T, C1060T, T2803C, T7513C, A29681C were the main single nucleotide polymorphisms (SNPs) of this epidemic. Cox regression analysis showed that age, underlying disease, clinical classification, vaccination, SNP T2803C and T7513C had an impact on the RNA shedding time of SARS-CoV-2. The adjusted multivariate Cox regression result showed that age [ HR=0.73, 95% CI (0.55, 0.95)] and T7513C [ HR=0.37, 95% CI (0.18, 0.77)] were still the risk factors for the extension of SARS-CoV-2 RNA shedding time. Conclusions:This study analyzed the effects of the individual factors and viral single nucleotide variations on the time of viral RNA shedding. Those who were older, suffered from hypertension, had more severe clinical symptoms, were not vaccinated or incompletely vaccinated, and had T7513C mutation in the infected virus, had a risk of a long RNA shedding time of SARS-CoV-2, which should be given special attention and follow-up after rehabilitation.

The caudate lobe of liver is anatomically divided into three parts: Spiegel portion, inferior vena cava portion and caudate process. The caudate lobe of the liver is located in the dorsal side of the liver, adjacent to the inferior vena cava, the three hepatic veins, and the left and right portal veins. The location of the caudate lobe depends on the location of anatomical landmarks and the location of staining, especially negative staining techniques. The left approach is suitable for Spiegel resection, and the right approach is suitable for paracentral resection of the inferior vena cava and caudate process. The dorsal approach and anterior approach combined with other approaches can achieve complete caudate resection. This article showed the combination of multimodal approach with total caudate lobectomy, partial caudate lobectomy and laparoscopic caudate lobectomy.
