Idiopathic pulmonary fibrosis (IPF) can be classified as pulmonary collateral disease,and its pathogenesis is mainly characterized by the loss of Qi meridian nourishment,the loss of Yin meridian nourishment,and the formation of blood stasis in the blood vessels. Qi Yin deficiency is the pathological basis that runs through IPF,and obstruction of meridians and collaterals is a key element in the development of the disease. The dysfunction of "spleen being in charge of the defensive function" is closely related to the formation of the pathological pattern of "lung deficiency and collateral stasis" in IPF. The term "spleen being in charge of the defensive function" originated from the Yellow Emperor's Inner Canon. If the spleen is healthy,the Qi will be filled with vitality. Positive energy is stored inside,evil cannot be dried up. Its concept is quite similar to the immune defense function in modern medicine. If the principle of "spleen being in charge of the defensive function" is lost,the key structure and function of the IPF alveolar epithelial barrier may be abnormal,and it can interact with various innate immune cells to promote inflammation and fibrosis processes. Therefore,this article explains the imbalance of immune homeostasis in IPF alveolar epithelium from two aspects:the barrier function of alveolar epithelial cells(AECs) and their interaction with innate immune cells. And based on the theory of "spleen being in charge of the defensive function",using traditional Chinese medicine for strengthening the spleen and nourishing Qi to treat IPF from the perspective of the spleen. This not only strengthens the scientific connotation of "spleen being in charge of the defensive function" in the pathogenesis of IPF,but also provides new research directions and ideas for its future clinical prevention and treatment.

Objective To explore the expression of coagulation indexes in rheumatoid arthritis (RA) and dry syndrome (pSS) and their relationships with inflammation and immune function. Methods A total of 61 patients with RA who were hospitalized in the Department of Rheumatology of Anhui Provincial Hospital of Traditional Chinese Medicine from March 12 to September 9, 2024 were selected as the RA group. And 61 patients with pSS who were hospitalized in the Department of Rheumatology of the same hospital September 4, 2023, to August 17, 2024, were selected as the pSS group. 61 healthy individuals who underwent routine medical checkups at the Physical Examination Center of Anhui Provincial Hospital of Traditional Chinese Medicine during the same period were included as the control group. Baseline clinical indexes before treatment were collected from patients in each group, including prothrombin time(PT), international normalized ratio(INR), thrombia time(TT), fibrinogen(FBG), activated partial thromboplastin time(APTT), fibrin (ogen) degradation products(FDP) and D-Dimer(D-D). Results The expression levels of PT, FBG, TT, FDP, and D-D in the RA group, the pSS group, and the normal group were significantly different. The expression levels of PT, FBG, FDP, and D-D in the RA group were all higher than those in the pSS group and the control group, respectively. And the expression level of TT in the pSS group was lower than that in control group. ROC curve analysis showed that the AUC of PT was 0.638, the AUC of FBG was 0.899, the AUC of FDP was 0.866, and the AUC of D-D was 0.919 in the RA group compared with the normal group. And the AUC of coagulation indexes for joint diagnosis of RA was higher than that of the indexes detected individually. pSS group had an AUC of PT of 0.618 compared with that of the normal group. The AUC of TT was 0.645, and the AUC of coagulation indexes for the joint diagnosis of pSS was higher than the AUC of each index detected separately. Association rule analysis showed that elevated D-D in RA patients had a significant correlation with elevated hs-CRP, CCP and RF, and elevated FBG had a significant correlation with elevated hs-CRP, ESR, RF and CCP. Elevated D-D in pSS patients had a correlation with elevated hs-CRP and anti-SSA, and elevated INR has correlation with elevated hs-CRP, anti-SSA and anti-SSB. Correlation analysis showed that PT, INR, FBG, FDP, and D-D were positively correlated with CRP and ESR, and TT was negatively correlated with CRP and ESR in the RA group. FBG, FDP, and D-D were positively correlated with CRP and ESR in the pSS group. Moreover, coagulation indexes were positively correlated with immune indexes in RA group and pSS group which were all significant. The results of multiple linear regression analysis showed that FBG was a positive correlate of hs-CRP and ESR in RA patients. For PSS patients, FBG and FDP were positive correlates of hs-CRP. APTT and FBG were positive correlates of ESR. Conclusion Compared with pSS, coagulation indexes (especially PT, FBG, FDP and D-D) are more informative for the early diagnosis of RA and the judgment of the degree of the disease, and can be used as an important predictor for the confirmation of the diagnosis of RA.

Congenital heart disease (CHD) is a congenital malformation resulting from abnormal embryonic development of the heart and great vessels, accounting for approximately 25% of all congenital malformations. Children with CHD are often complicated by short stature. Although surgical treatment can improve their growth and development to a certain extent, some children still experience growth retardation after surgery. Recombinant human growth hormone (rhGH) is the main drug for treating short stature, but its efficacy and safety in the treatment of patients with concomitant CHD warrant further investigation. This article reports six cases of children with CHD and short stature who were treated with rhGH. Through a literature review, we summarize and discuss the therapeutic efficacy, follow-up experiences, and adverse reactions of rhGH treatment, aiming to provide references for clinicians in applying rhGH to treat patients with CHD and short stature.

BACKGROUND:Pulsed electromagnetic field is a non-invasive and non-radiative treatment method.Clinical use of pulsed electromagnetic fields in the treatment of orthopedic diseases has achieved certain results. OBJECTIVE:To review the current clinical application of the pulsed electromagnetic field in the treatment of orthopedic diseases,providing a scientific theoretical basis for the clinical treatment of orthopedic diseases. METHODS:The first author used a computer to search PubMed,CBM,Cochrane Library,CNKI,and WanFang Data for related studies on the pulsed electromagnetic field in the treatment of orthopedic diseases,using the keywords of"pulsed electromagnetic field,orthopedics,osteoarthritis,osteoporosis,bone healing,electromagnetic navigation"in English and Chinese.For the literature related to the same content,recent publications were selected.A total of 69 articles were selected from the search results for review. RESULTS AND CONCLUSION:Pulsed electromagnetic field has a definite curative effect on fracture healing.It can be used in the treatment of osteomyelitis by antibacterial,bactericidal,anti-inflammatory and promoting bone healing,and can inhibit osteoporosis and its progress.In addition,the treatment of early osteoarthritis,femoral head necrosis and postoperative rehabilitation of late joint replacement through various ways can become a treatment for orthopedic diseases.However,the therapeutic mechanism of the pulsed electromagnetic field for a variety of orthopedic diseases is still unclear,and most of the research is still in the primary stage.In the future,it is still necessary to obtain more reliable evidence from high-quality research and clinical trials to provide a more perfect basis for the clinical treatment of orthopedic diseases.

Objective:To investigate the utility of 68Ga-fibroblast activation protein (FAP) inhibitor (FAPI)-04 PET imaging in assessing the therapeutic response in pressure overload-induced heart failure. Methods:Rat models of pressure overload-induced heart failure were established by abdominal aortic constriction (AAC). Thirty rats were categorized into AAC group, 7 days reverse AAC (rAAC) group, and sham operation (sham) group ( n=10 per group) using completely random grouping method. All rats underwent 68Ga-FAPI-04 PET/CT imaging at 4 and 8 weeks after the ACC operation, while echocardiography, pathological examination, and immunohistochemical analysis were performed at 8 weeks postoperation. One-way analysis of variance, independent-sample t test and Pearson correlation analysis were used for data analysis. Results:68Ga-FAPI-04 PET/CT imaging showed that the target-to-background ratios of the heart and liver had significant differences among three groups both at 4 and 8 weeks postoperation ( F values: 2 547.12, 2 041.71, 462.65, 1 210.97, all P<0.001). Echocardiography revealed left ventricular ejection fraction (LVEF), left ventricular internal diameter at end-diastole (LVIDd), and left ventricular internal diameter at end-systole (LVIDs) in three groups at 8 weeks postoperation were significantly different ( F values: 118.92, 9.11, 10.63, all P<0.01). Rats were sacrificed at 8 weeks postoperation, and Masson staining showed that the fibrosis in the heart and liver of the rAAC group was significantly improved compared with that of the AAC group, and immunohistochemical analysis revealed significantly lower FAP levels in the heart and liver of the rAAC group compared with those of the AAC group ( t values: from -11.27 to -4.16, all P<0.01). FAPI uptake in the heart of the AAC group and rAAC group at 8 weeks postoperation were significantly positively correlated with FAPI uptake in the liver, LVIDd and LVIDs, FAPI uptake in the heart was significantly negatively correlated with LVEF, and FAPI uptake in the heart and liver were significantly positively correlated with fibrosis degree and FAP levels of corresponding organs ( r values: -0.89, -0.88, 0.72-0.97, all P<0.05). Conclusions:68Ga-FAPI-04 PET/CT can show the improvement process of cardio-liver fibrosis following the unloading of excessive pressure in heart failure. Myocardial FAPI uptake is closely related to the extent of heart failure improvement.

Objective:To investigate whether Lycopi Herba can serve as a viable alternative to Alismatis Rhizoma in the treatment of heart failure (HF) through network pharmacology and molecular docking techniques.Methods:TCMSP database was used to filter active components of Lycopi Herba and Alismatis Rhizoma. SwissTargetPrediction database was used to predict potential targets. HF-related targets were collected from databases such as GeneCards, OMIM, and DisGeNET. Venny 2.1.0 was used to draw a Venn diagram illustrating the intersection of targets between Lycopi Herba and Alismatis Rhizoma and HF. A protein-protein interaction (PPI) network was established using the String database, and key targets for the treatment of HF with Lycopi Herba and Alismatis Rhizoma were selected using Cytoscape 3.9.1 software to construct a component-intersection target network. The intersection targets were then analyzed for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways using Metascape. Molecular docking techniques were used to evaluate the affinity between active components and key targets.Results:Lycopi Herba primarily targeted pivotal proteins such as HMGCR and CYP27B1, while Alismatis Rhizoma had a broader target spectrum, including PPARA, JAK2, among others. Shared key targets between the two included HMGCR and ESR1, which were primarily involved in cholesterol synthesis and steroid hormone biosynthesis. Enrichment pathway analysis showed similarities in steroid metabolism between the two; Alismatis Rhizoma, however, was more likely to act through protein phosphorylation regulation and modulating the PI3K-Akt signaling pathway for HF treatment. A unique target for Lycopi Herba in treating HF was CHRM4, indicating its potential for blood pressure regulation and myocardial protection.Conclusions:Both Lycopi Herba and Alismatis Rhizoma exhibit certain commonalities in the treatment of HF, but Alismatis Rhizoma has a wider range of targets and signaling pathways, implying more extensive therapeutic potential. However, considering the nephrotoxicity of Alismatis Rhizoma, Lycopi Herba could be considered as an alternative treatment for HF, especially in patients with renal insufficiency or in the early stages of HF.

Systemic lupus erythematosus (SLE) is a diffuse, systemic autoimmune disorder that can impact multiple organs and systems, with patients exhibiting abnormal levels of various autoantibodies and immune markers in their serum. It is currently understood that dysregulation of B cells activation plays a pivotal role in the pathogenesis of SLE, as aberrantly activated B cells produce autoantibodies that inflict damage on multiple organs through complement activation and antibody-dependent cell-mediated cyto-toxicity. Traditional therapies for SLE may prove ineffective for certain patients or lead to adverse reactions. In most instances, conventional treatment merely alleviates symptoms and necessitates lifelong immunotherapy. A limited number of clinical cases have explored chimeric antigen receptor T cells (CAR-T) therapy as a potential treatment for autoimmune diseases such as SLE. Research indicates that CAR-T can specifically target CD19 expressed on the surface of B cells and plasma cells, achieving profound depletion while minimizing drug-related side effects. This report details a female patient diagnosed with SLE and lupus nephritis who was successfully treated using dual-targeting B cells maturation antigen CAR-T by our research team; following treatment, she ceased steroid and immunomodulator use, attaining sustained remission without these medications. The patient was a 23-year-old female. Multiple examinations in other hospitals and in our hospital showed positive anti-double-stranded DNA (dsDNA) antibody and low complement C3. Renal biopsy in our hospital showed lupus nephritis Ⅳ-G (A/C), and National Institutes of Health (NIH) activity index (AI) score=4. She was diagnosed with "SLE, lupus nephritis (LN)". She was treated with hormones, immunosuppressants and Chinese medicine, but the effect was not good. After the CAR-T treatment, She stopped using hormones and immune agents and achieved continuous remission with zero hormones and zero immune agents. She became pregnant six months after CAR-T infusion, and gave birth to a healthy full-term, full-weight baby successfully. She is the first patient in China who successfully discontinued hormone, immune preparations and gave birth after CAR-T therapy. During the follow-up of the patient, we found that the immune indexes had basically returned to normal, and the safety was good. It indicates that CAR-T therapy may represent a promising and innovative therapeutic approach for the management of SLE. This offers hope and establishes a precedent for SLE women of childbearing age.
