Objective To explore the effect of follow-up management based on the digital information platform on the compliance of early screening and follow-up of liver cancer in patients with chronic liver diseases,and to provide a management method for clinical practice.Methods Convenience sampling was adopted to include 3,959 patients who had chronic liver diseases and visited the outpatient clinic of the Department of Infectious Liver Diseases in our hospital from January 2022 to December 2023.Before the application of the digital information platform for management,it was the medical staff of the Infectious Liver Disease Department who conducted telephone follow-ups and handwritten registrations for patients with chronic liver diseases within one week after their visits.After management,A liver cancer prediction model installed in the digital information platform of the hospital automatically collected data of the patients,including information about the diseases and results of examinations for intelligent risk stratification of liver cancer.The nurses who were in charge of the follow-up performed individualised follow-up reviews based on the levels of risk.Follow-up re-visit rate of the patients in very high-and high-risks were calculated.Scores of chronic disease self-efficacy and medication compliance were compared before and at 3 months after the follow-up management.Results A total of 3,860 patients completed the study.After the follow-up management,the total follow-up re-visit rate of the patients was 88.2%(1,818/2,062)and that of the high-risk patients was 95.3%(246/258)in 2022,while those in 2023 were 94.0%(1,691/1,798)and 98.3%(232/236),respectively.After 3 months of follow-up management,scores for medication compliance and chronic disease self-efficacy showed significant improvement in comparison with those before the implementation of follow-up management(P<0.001).Conclusion The follow-up management based on a digital information platform is suitable for screening of early liver cancer in the patients with chronic liver diseases,as it improves the re-visit rate of patients for follow-up,medication compliance and self-efficacy.

This paper summarizes clinical experience in treating depression with a combined approach of acupuncture and herbal medicine under the guiding principle of deficiency and excess. Given the complex pathogenesis of depression， it is proposed that syndrome differentiation based on deficiency and excess should serve as the overarching principle. Acupuncture is prioritized， supplemented by Chinese herbal medicine. Acupuncture is based on the spirit-regulating protocol； for excess syndromes， it is combined with the calming and restoring protocol， while for deficiency syndromes， it is combined with the five zang organs tonification protocol. In cases of mixed deficiency and excess， the two protocols are alternated， and adjustments are made dynamically throughout the treatment based on syndrome evolution. Herbal prescriptions are also guided by the differentiation of deficiency and excess. For excess patterns， dispersion and clearance should be emphasized， focusing on soothing the liver， clearing heat， relieving irritability， regulating qi， transforming phlegm， and calming the mind； for deficiency patterns， tonification is emphasized， aiming to strengthen the spleen， nourish the blood， calm the spirit， tonify qi， and consolidate the root.

Objective To establish a mouse model of infection with the minimum lethal dose of Vibrio vulnificus(V.vulnificus)and to evaluate the protective efficacy of inactivated whole-cell(IWC)vaccine using this model.Methods A mouse model of lethal-dose infection was established by intraperitoneal injection of different doses of V.vulnificus.Bacterial colonization in the organs was detected with tissue homogenate plating,and pathological changes in the organs were observed after tissue section staining.Flow cytometry was used to detect immune cell responses after liver tissues were digested into single-cell suspension.IWC vaccine of V.vulnificus was prepared,and the mice were immunized through different routes to observe the protective efficacy of the vaccine.Results A mouse model of infection with the minimum lethal dose at 1×106 CFU of V.vulnificus was successfully established.After infection,the bacteria were mainly colonized in the liver of mice and caused severe pathological damages.Compared with the uninfected mice,the proportion of neutrophils in the liver was significantly increased in the infected mice,whereas the proportions of B cells and T cells were correspondingly decreased(P<0.05).A single intramuscular or intraperitoneal injection of the IWC vaccine could protect the mice effectively against lethal infection of V.vulnificus in 7 d later(P<0.01),although the level of serum IgG having no significant increase.Conclusion A mouse model of lethal-dose infection with V.vulnificus is successfully established,with histopathological characteristics.The IWC vaccine of V.vulnificus rapidly mediates immune protection in this model probably independent of IgG.

Objective:To investigate the impact of immunosuppressive therapy on the severity of SARS-CoV-2 infection and cytokine levels in pediatric patients with kidney diseases.Methods:A retrospective analysis was conducted on the clinical data of 40 hospitalized pediatric patients who were diagnosed with SARS-CoV-2 infection at the 900th Hospital of PLA Joint Logistic Support Force from December 2022 to February 2023. Based on their immunosuppressive status prior to SARS-CoV-2 infection, these patients were categorized into immunosuppressive group and non-immunosuppressive group. Independent sample t-tests, Mann-Whitney U tests, and χ2 test were employed to compare the clinical baseline characteristics and laboratory data, the severity of SARS-CoV-2 infection, and the levels of cytokines between the 2 groups. Results:Among the 40 patients, 11 were in the immunosuppressive group (aged 13 (8, 14) years, 9 males and 2 females) and 29 in the non-immunosuppressive group (aged 2 (1, 4) years, 15 males and 14 females). In the immunosuppressive group, 2 were asymptomatic cases, 8 were mild cases, and 1 was moderate case, and there was no severe or critical cases. In the non-immunosuppressive group, 8 were mild cases, 5 were moderate, 15 were severe cases, 1 was critical case, and no asymptomatic cases. The underlying diseases in the immunosuppressive group included nephrotic syndrome (6 cases), IgA vasculitis nephritis (2 cases), lupus nephritis (1 case), post-renal transplantation (1 case), and renal failure (1 case), with a mean total immunosuppression score (TIS) of (3.6±1.4) points. In the non-immunosuppressive group, 2 patients had a history of epilepsy, and the remaining 27 cases had no underlying conditions, all with TIS scores of 0. Compared to the children in the non-immunosuppressive group, those in the immunosuppressive group were more likely to exhibit asymptomatic or mild infection, with lower risks of severe disease, cytokine storm, fever, and cough, but a higher risk of fatigue ( OR=1.22, 2.66, 0.48, 0.12, 0.12, 0.13, 1.22; 95% CI 0.93-1.62, 0.99-7.15, 0.33-0.70, 0.03-0.57, 0.03-0.57, 0.03-0.65, 0.93-1.62; all P<0.05). The levels of cytokine IL-6, interferon-α and interferon-γ in the immunosuppressive group were all lower than those in the non-immunosuppressive group ( Z=2.23, 2.51, 2.92, respectively; all P<0.05). Conclusion:Pediatric patients with kidney diseases receiving appropriate immunosuppressive therapy may mitigate the severity of SARS-CoV-2 infection by suppressing the expression of cytokines.

Objective:To investigated the safety and efficacy of donor-derived CD19+ or sequential CD19+ CD22+ chimeric antigen receptor T-cell (CAR-T) therapy in patients with B-cell acute lymphoblastic leukemia (B-ALL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:The data of 22 patients with B-ALL who relapsed after allo-HSCT and who underwent donor-derived CAR-T therapy at the Zhujiang Hospital of Southern Medical University and the 920th Hospital of Joint Logistics Support Force of the People’s Liberation Army of China from September 2015 to December 2022 were retrospectively analyzed. The primary endpoint was overall survival (OS), and the secondary endpoints were event-free survival (EFS), complete remission (CR) rate, and Grade 3-4 adverse events.Results:A total of 81.82% ( n=18) of the 22 patients achieved minimal residual disease-negative CR after CAR-T infusion. The median follow-up time was 1037 (95% CI 546–1509) days, and the median OS and EFS were 287 (95% CI 132-441) days and 212 (95% CI 120-303) days, respectively. The 6-month OS and EFS rates were 67.90% (95% CI 48.30%-84.50%) and 58.70% (95% CI 37.92%-79.48%), respectively, and the 1-year OS and EFS rates were 41.10% (95% CI 19.15%-63.05%) and 34.30% (95% CI 13.92%-54.68%), respectively. Grade 1-2 cytokine release syndrome occurred in 36.36% ( n=8) of the patients, and grade 3-4 occurred in 13.64% of the patients ( n=3). Grade 2 and 4 graft-versus-host disease occurred in two patients. Conclusion:Donor-derived CAR-T therapy is safe and effective in patients with relapsed B-ALL after allo-HSCT.

Objective:To investigate imaging characteristics of papulopustular rosacea (PPR) by high-frequency ultrasound combined with color Doppler flow imaging.Methods:From August 2021 to August 2022, 30 patients with PPR were enrolled from the Department of Dermatology, the First Affiliated Hospital of Baotou Medical College in the Inner Mongolia Autonomous Region, and 30 healthy volunteers served as controls. The 22-MHz high-frequency ultrasound combined with color Doppler blood flow imaging was performed to measure the skin thickness, echo and blood flow parameters at the cheek, and the ultrasound results were compared between the two groups. Comparisons between groups were conducted by using t test or chi-square test. The diagnostic value was analyzed using the area under the curve (AUC) in the receiver operating characteristic (ROC) curve. Results:In the case group, there were 12 males and 18 females, and their ages ranged from 22 to 65 years (42.3 ± 12.8 years) ; in the control group, there were 10 males and 20 females, and their ages ranged from 24 to 62 years (41.0 ± 8.4 years) . The epidermal and dermal thicknesses at the cheek were significantly higher in the case group (132.64 ± 12.29 μm, 1 812.29 ± 85.52 μm, respectively) than in the control group (104.34 ± 14.45 μm, 1 671.77 ± 146.55 μm, respectively, both P < 0.05) . High-frequency ultrasound images showed that the case group was mainly characterized by irregular hypoechoic areas in the cheek dermis (80%) , while banded moderately echoic areas were common in the cheek dermis in the control group (90%) ; subepidermal low-echogenic bands and dermal irregular hypoechoic areas were more likely to appear in the case group than in the control group (93.33% vs. 43.33%, 80% vs. 10%, respectively, both P < 0.001) . Compared with the control group, the case group showed a significantly increased proportion of patients with abundant blood flow signals (93.3% vs. 10%, P < 0.05) , and significantly increased blood vessel diameters (1.60 ± 0.42 mm vs. 0.95 ± 0.32 mm, P < 0.05) ; there was no significant difference in peak systolic blood flow velocity and vascular resistance index between the two groups (both P > 0.05) . The AUC of high-frequency ultrasound combined with color Doppler flow imaging quantitative parameters (including epidermal thicknesses, dermal thicknesses, and blood vessel diameters) was 0.989 (95% CI: 0.970 - 1.000) for the diagnosis of PPR, and the sensitivity and specificity were both 96.7%, which were higher than those of single parameter-based diagnostic model. Conclusion:High-frequency ultrasound combined with color Doppler flow imaging can help improve the accuracy of the diagnosis of PPR, by accurately and non-invasively measuring skin thickness and blood flow parameters.
