Objective To observe the clinical effect of Jiu-Wei-Yong-An granule combined with cetirizine in the treatment of damp-heat accumulation syndrome of eczema. Methods 108 eczema patients with syndrome of damp-heat accumulated in the skin, treated in the Department of Traditional Chinese Surgery in the First Affiliated Hospital of Naval Medical University from December 2021 to March 2023, were selected. They were randomly divided into an observation group and a control group, 54 cases in each. Both groups took cetirizine tablets orally for basic treatment. The observation group was given Jiu-Wei-Yong-An granules, and the control group was given placebos of the same. The clinical efficacy before and after treatment in the two groups was observed and compared, including TCM syndrome scores, eczema area and severity index （EASI）, visual analogue scale （VAS）, and adverse reactions. Results After treatment, the total effective rate of the observation group （88.9%） was higher than that of the control group （77.8%）, and the difference was statistically significant （P<0.05）. After treatment, the TCM syndrome score, EASI and VAS in the observation group were significantly lower than those in the control group （P<0.05）, and the difference was statistically significant. There was no significant difference in the total rate of adverse reactions between the two groups （P>0.05）. Conclusion The combination of Jiu-Wei-Yong-An granules and cetirizine tablets in the treatment of damp-heat eczema showed significantly better clinical outcomes in the observation group compared to the control. It effectively improved patient conditions, reduced skin lesion areas, and alleviated itching, with both safety and efficacy that merit clinical promotion.

Objective To evaluate the clinical efficacy of Traditional Chinese Medicine （TCM）external treatment methods in alleviating skin pruritus caused by eczema through a Meta-analysis. Methods Randomized clinical trials investigating the use of TCM external treatment methods for skin pruritus caused by eczema were searched in databases including China National Knowledge Infrastructure （CNKI）, VIP, Wanfang, Sinomed, PubMed, Embase, LILACS, and Cochrane, up to December 2024. Two reviewers independently screened and entered the statistical data, conducted bias risk assessment by the Cochrane Handbook for Systematic Reviews of Interventions, version 5.1.0, and performed Meta-analysis using RevMan 5.4.1. Results Ultimately, 14 studies involving 1 788 patients were included. Compared to the control group, TCM external treatment methods （treatment group）showed better improvement in pruritus scores （Z=11.88, P<0.000 01）, better improvement in Eczema Area and Severity Index （EASI） scores （Z=23.15, P<0.000 01）, higher overall clinical efficacy rate （Z=6.21, P<0.000 01）, better improvement in TCM symptoms （Z=5.49, P<0.000 01）, and lower clinical recurrence rate （Z=2.88, P=0.004）. Three of the included studies mentioned adverse reactions, with the treatment group showing lower adverse reactions than the control group. Conclusion The external treatment of TCM was more effective in treating skin pruritus caused by eczema compared to the control group. Given the biases and heterogeneity in the included literature, this conclusion needs to be further substantiated by more large-scale, multi-center, randomized, controlled, and double-blind studies.

In recent years, the incidence of multiple primary lung cancer (MPLC) has been increasing, and it cannot be ignored in clinical practice. The treatment of MPLC is still controversial, but surgical treatment is recognized as the most important treatment. However, current studies have shown that the treatment of MPLC needs to develop multimodal treatment according to different patients. This review summarizes multiple treatment method for MPLC, including surgery, ablation, chemotherapy, radiotherapy, targeted therapy, and immunotherapy in order to enhance understanding of MPLC treatment.

Objective:To investigate the effects of cardiomyocyte-specific TSHR knockout on myocardial insulin resistance in a mouse model of heart failure.Methods:A cardiomyocyte-specific TSHR knockout(TSHR CKO) mouse model was generated by crossing TSHR flox/flox mice with α-MHC-Cre transgenic mice. F1 offspring(TSHR flox+ /-α-MHC-Cre+ mice) were interbred to obtain TSHR CKO mice, and littermate TSHR flox/flox mice served as controls. Fasting blood glucose levels were measured using a Roche glucometer, and fasting insulin levels were determined using a mouse insulin ELISA kit. Cardiac function and the expression of ANP, BNP, β-MHC, IRS-1, IRβ, GLUT-4, phosphorylated IRS-1, phosphorylated IRβ, and TSHR in myocardial tissues were assessed by echocardiography, RT-qPCR, Western blot, and immunohistochemistry(IHC). IHC was also used to evaluate the myocardial expression of IRS-1 and GLUT-4, while Masson′s trichrome staining was performed to assess the degree of myocardial fibrosis. Comparisons between groups were made using ANOVA. Results:The insulin resistance index indicated no systemic insulin resistance in all groups. Echocardiography revealed that compared with the FLOX group, the FLOX-ISO group exhibited significant reductions in left ventricular ejection fraction(LVEF), left ventricular fractional shortening(LVFS), left ventricular end-systolic volume(LVESV), and left ventricular end-diastolic volume(LVEDV), along with increases in heart weight-to-body weight(HW/BW), left ventricular end-systolic diameter(LVESD), and left ventricular end-diastolic diameter(LVEDD). Compared with the FLOX-ISO group, the CKO-ISO group showed significantly increased LVEF and decreased LVESV, LVEDV, LVESD, and LVEDD. Immunohistochemistry results demonstrated that myocardial TSHR knockout increased the expression of IRS-1 and GLUT-4. Additionally, RT-qPCR and Western blotting showed that ANP, BNP, and β-MHC expression levels were reduced, while IRS-1, IRβ, and GLUT-4 expression levels were elevated in TSHR CKO mice. Conclusion:Cardiomyocyte-specific TSHR knockout improves myocardial insulin resistance in mice with heart failure.

Objective:To investigate the clinical features, pathologic characteristics, treatment and prognosis of primary mediastinal large B-cell lymphoma (PMBCL) in children.Methods:Clinical data including clinical manifestations, treatment, clinical efficacy of 8 cases of childhood PMBCL treated in Beijing Children′s Hospital, Capital Medical University from March 2017 to February 2024 were collected retrospectively, the clinical characteristics and prognosis of them were summarized.Results:Among the 8 children, there were 5 males and 3 females. The age at the time of initial diagnosis was 11.0 (10.3, 13.5) years. The first clinical symptoms were cough (8 cases) and stridor (6 cases). The lesions most often involved the mediastinum (8 cases), lungs (5 cases, hilum more often), pericardium (5 cases), and pleura (4 cases). Extra thoracic invasion was present in 4 cases, 7 cases had huge tumor lesions and 7 cases were phase Ⅲ clinical stage. Except for 1 case who underwent surgical resection of the tumor, the remaining 7 cases were treated with DA-EPOCH+R (dose adjusted-etoposide+prednisone+vincristine+cyclo-phosphamide+doxorubicin+rituximab) chemotherapy. The follow-up time was 25.0 (10.5, 43.3) months, with 7 cases in complete and partial metabolism response, 1 case had disease progression. All 8 cases survived.Conclusions:PMBCL is most common in school-age boys and most of them present with huge mediastinal tumor focus. PMBCL expresses B-cell spectrum antigens and weakly expresses CD30.The application of DA-EPOCH+R is effective in the treatment of PMBCL in children.

Objective:To evaluate the clinical characteristics, pathology, treatment and prognosis of blastic plasmacytoid dendritic cell neoplasm (BPDCN) in children.Methods:Clinical data (including gender, age of disease onset, affected sites, treatment, timing of allogeneic hematopoietic stem cell transplantation (allo-HSCT), etc.) of 7 children with BPDCN who were admitted to Beijing Children′s Hospital, Capital Medical University from December 2018 to December 2023 were analyzed retrospectively. Clinical outcomes were also assessed, with patients followed up until December 2024.Results:Among 7 patients, there were 3 males and 4 females. Age at disease onset ranged from 3.2 to 12.9 years. Initial presentations included subcutaneous nodules in 5 cases, rash in 1 case, and ankle pain in 1 case. Extra-cutaneous involvement was seen in the bone marrow, lymph nodes, and central nervous system. Six patients received induction chemotherapy using a modified lymphoblastic lymphoma regimen, 1 patient received the high-risk protocol for pediatric lymphoblastic lymphoma/leukemia and salvage therapy regimens. Allo-HSCT was performed soon after chemotherapy remission. The time to bridge allo-HSCT was 3.5 to 6.5 months. The follow-up time was 1.6 to 6.0 years. Six patients were in disease-free survival, while 1 patient survived with disease after recurrence following transplantation.Conclusions:BPDCN is rare in children and presents diverse clinical manifestations, with skin involvement being the predominant feature. Early allo-HSCT following complete remission with chemotherapy can improve prognosis.

Objective To explore the clinical value of inflammatory prognostic index combined with dual-source CT perfusion imaging in predicting early response of hepatocellular carcinoma(HCC)after transcatheter hepatic artery chemoembolization(TACE).Methods A total of 25 patients with HCC,who met the inclusion criteria and received initial TACE at the First Affiliated Hospital of Dali University of China from November 2022 to November 2023,were prospectively collected.CT perfusion scan was performed before TACE as well as in 30-40 days after TACE,and blood routine and blood biochemical data were collected.The modified Response Evaluation Criteria in Solid Tumors(mRECIST)was used to evaluate postoperative enhanced CT manifestations.Patients obtaining complete remission(CR)or partial remission(PR)were classified as effective group(n=14),and patients obtaining stable disease(SD)or progression disease(PD)were classified as ineffective group(n=11).The differences in CT perfusion imaging parameters and inflammatory parameters between the two groups were analyzed,and the predictive values of preoperative CT perfusion imaging parameters and inflammatory parameters for postoperative early response of HCC were evaluated.The cutoff value was taken at the maximum Youden index.Univariate analysis and multivariate analysis were used to analyze the effect of CT perfusion imaging parameters,inflammatory parameters and clinical features on the prognosis.The nomogram prediction model was constructed by using R software.Results The post-TACE arterial liver perfusion(ALP),hepatic perfusion index(HPI),blood flow(BF)and blood volume(BV)were significantly lower than their pre-TACE values(all P＜0.05).Afer TACE portal vein perfusion(PVP)was obviously higher than that before operation(P＜0.05).No statistically significant differences in the mean transit time(MTT),flow extraction product(FED),C-reactive protein(CRP),albumin(ALB),neutrophil/lymphocyte ratio(NLR)and inflammatory prognosis index(IPI)existed between the pre-TACE values and post-TACE values(all P＞0.05).The pre-TACE ALP,BF and FED in the effective group were significantly higher than those in the ineffective group,while the pre-TACE CRP and IPI in the effective group were remarkably lower than those in the ineffective group(P＜0.05).There were no statistically significant differences in pre-TACE PVP,HPI,MTT,BV,ALB and NLR between the effective group and the ineffective group before(all P＞0.05).In the effective group,the pre-TACE ALP,HPI,BF,BV and FED were obviously higher than their post-TACE values(all P＜0.05)preoperative PVP was significantly lower than postoperation(P＜0.05),while no statistically significant differences in MTT,CRP,ALB,NLR and IPI existed between the pre-TACE values and the post-TACE values(all P＞0.05).In the ineffective group,the pre-TACE HPI was prominently higher than the post-TACE value(P＜0.05),while no statistically significant differences in ALP,PVP,BF,BV,MTT,FED,ALB,CRP,NLR and IPI existed between the pre-TACE values and the post-TACE values(all P＞0.05).The pre-TACE ALP,BF,BV,FED,CRP and IPI had high predictive values in judging early response of HCC after TACE(all P＜0.05),the AUC values were 0.831,0.779,0.740,0.753,0.779 and 0.805 respectively,and the optimal cutoffs were 33.280 mL/100 mL min,61.860 mL/100 mL min,5.885 mL/100 mL,29.725 mL/100 mL min,30.465 mg/L,1.885 respectively.ALP combined with CRP had the highest predictive value for post-TACE early response of HCC,with an AUC of 0.968(95％CI:0.906-1.000,P＜0.05),ALP combined with IPI could significantly improve the predictive value,with an AUC of 0.961(95％CI:0.894-1.000,P＜0.05),with the sensitivity and specificity being 0.929 and 0.909 respectively.Multivariate analysis showed that pre-TACE ALP and CRP were the independent influencing factors for post-TACE early response of HCC(P＜0.05).The nomogram prediction model constructed based on the pre-TACE ALP and CRP could effectively predict the post-TACE early response of HCC,and the AUC value was 0.968(95％CI:0.908-1.000).Conclusion ALP and CRP can be used to predict the post-TACE early response of HCC,and the combination use of ALP and CRP can significantly improve the predictive value.

Cartilage tissue engineering offers a novel therapeutic approach for auricular, tracheal, and joint reconstruction. Nevertheless, once implanted into the body, tissue-engineered cartilage is confronted with host immune rejection and inflammatory responses. These responses can result in cartilage deformation and fibrosis, thereby affecting the long-term maintenance of its morphology and function. Effectively modulating immune and inflammatory responses is crucial for advancing the clinical application of engineered cartilage. This article reviewed relevant literature to analyze the mechanisms of inflammatory responses occurring after the implantation of tissue-engineered cartilage, and summarized the types and surface characteristics of biomaterials, providing a reference for the design of biomaterials in cartilage tissue engineering.
