ObjectiveTo investigate the therapeutic effects of Chaipo decoction on bronchial asthma in rats and its regulatory effects on the nucleotide-binding oligomerization domain-like receptor pyrin domain-containing protein 3 （NLRP3）/cysteinyl aspartate-specific protease-1 （Caspase-1）/Gasdermin D （GSDMD） pathway， aiming to elucidate its mechanism in ameliorating pyroptosis. MethodsSixty male Sprague-Dawley （SD） rats were randomly divided into six groups （n=10 per group）： normal control， asthma model， Chaipo decoction low-dose （5.0 g·kg^-1）， medium-dose （10.0 g·kg^-1）， high-dose （20.0 g·kg^-1）， and dexamethasone （1.0 mg·kg^-1）. The asthma model was established in all groups except the normal control group via ovalbumin （OVA） sensitization and challenge. Rats in the Chaipo decoction groups received intragastric administration of Chaipo decoction at the corresponding doses， while the dexamethasone group was treated with dexamethasone. The normal and model groups were administered equivalent volumes of saline. After 14 days of intervention， asthma symptom scores were assessed. Dynamic lung compliance （Cdyn）， lung resistance （RL）， and functional residual capacity （FRC） were measured using a small animal pulmonary function testing system. Lung tissue pathology was evaluated by hematoxylin-eosin （HE）， Masson's trichrome， and periodic acid-Schiff （PAS） staining. Levels of interleukin （IL）-6， IL-1β， and IL-18 in bronchoalveolar lavage fluid （BALF） were determined by enzyme-linked immunosorbent assay （ELISA）. Expression of NLRP3 and apoptosis-associated speck-like protein （ASC） in lung tissues was assessed by immunohistochemistry （IHC）. Protein levels of NLRP3， Caspase-1， GSDMD， and other pyroptosis-related proteins were measured by Western blot. ResultsCompared with the normal group， the model group exhibited significantly increased asthma symptom scores， inflammatory scores， collagen deposition， PAS scores， RL， FRC， levels of IL-6， IL-1β， and IL-18 in BALF， and expression levels of NLRP3， ASC， and other pyroptosis-related proteins in lung tissue （P0.01）， while Cdyn was significantly decreased （P0.01）. Compared with the model group， all doses of Chaipo decoction markedly improved asthma symptoms， with significantly reduced symptom scores （P0.05， P0.01）. Pulmonary function analysis showed that medium and high doses of Chaipo decoction significantly increased Cdyn （P0.05， P0.01） and decreased RL and FRC （P0.05， P0.01）. Histopathological evaluation indicated that high-dose Chaipo decoction significantly reduced inflammatory scores， collagen deposition， and goblet cell hyperplasia in lung tissue （P0.05， P0.01）. ELISA results showed that all doses of Chaipo decoction significantly decreased IL-6， IL-1β， and IL-18 levels in BALF （P0.05， P0.01）. IHC and Western blot analyses demonstrated that medium and high doses of Chaipo decoction markedly downregulated NLRP3， ASC， and other pyroptosis-related proteins in lung tissue （P0.05， P0.01）. ConclusionChaipo decoction effectively improves pulmonary function and pathological damage in asthmatic rats， potentially by inhibiting the NLRP3/Caspase-1/GSDMD pathway and reducing pyroptosis.

The theory of five spirits(mind,eternal soul,corporeal soul,consciousness and will)is an important part of traditional Chinese medicine(TCM)theory,which reveals the human mental and psychological activities.Five-spirit theory takes the shape of modern cognitive psychology.Language is an important part of cognitive activities.Under the guidance of the five-spirit theory of TCM,and by combining the research results of modern cognitive psychology,this paper initially constructs a language processing model,and proposes that heart-mind,spleen-consciousness,kidney-will,and liver-soul are all involved in the formation of language.Moreover,the pathogenesis of post-stroke aphasia(PSA)is explored from the perspective of the five spirits.It is proposed that PSA refers to the comorbidity of body and spirit,and its pathogenesis is related to the disorders of the five spirits.After analyzing the clinical manifestations of PSA,it is suggested that malnutrition of heart-mind and insufficient kidney-will contribute to the pathogenesis of auditory comprehension and reading obstacles in patients with PSA,and the deactivation of liver-soul is closely related to spontaneous speech and naming obstacles.The treatment of PSA should be focused on nourishing blood and tranquilizing mind,enhancing consciousness and strengthening will,and suppressing liver to tranquilize soul.And the prescriptions of Pingbu Zhenxin Pills,Zhiyi Decoction plus Dingzhi Pills,and Dinghun Decoction can be chosen for modified use.The acupuncture and moxibustion can also be used for PSA,by performance mainly on the acupoints of heart meridians,pericardial meridians,spleen meridians,kidney meridians and liver meridians.The syndrome differentiation and treatment system for PSA with the combination of Chinese medicine and acupuncture based on the five-spirit theory makes up for the shortcomings of stress on the physique while ignorance of the spirit in the conventional zang-fu organ syndrome differentiation,and expands the methods for early intervention of PSA with TCM and approaches to improve the prognosis of rehabilitation.

AIM:This study utilized CRISPR/Cas9 technology to create Retnlb floxp knock-in mice,followed by the application of the Cre-LoxP recombination system to generate intestinal epithelial-specific Retnlb gene knockout mice(Retnlb-CKO).This model was developed to investigate the pathogenic mechanisms of Retnlb in inflammatory bowel disease.METHODS:Female and male C57BL/6N mice,aged 8 weeks with the Retnlbflox/+genotype,were housed togeth-er for breeding.Offsprings were screened to identify those with the Retnlbflox/flox genotype.These mice were then crossed with Vil1-Cre transgenic mice,which express Cre recombinase specifically in intestinal epithelial cells,resulting in Retnlb-flox/+,Cre+mice.Subsequent crosses between Retnlbflox/+,Cre+mice and Retnlbflox/flox mice produced Retnlbflox/flox,Cre+mice(Retnlb-CKO).Six 8-week-old Retnlbflox/flox,Cre+mice and their littermate Retnlbflox/flox mice were selected for experiments.RT-qPCR and immunohistochemistry were used to assess Retnlb mRNA and protein levels in colonic epithelium.Phenotypic observa-tions included body length,weight,diet,and reproductive capability.Tissue-to-body weight ratios were calculated to ana-lyze growth and development.Intestinal barrier integrity and colonic expression of inflammatory factors were evaluated.RESULTS:The conditional gene knockout mouse model with specific deletion of Retnlb in intestinal epithelial cells was successfully established and validated through genetic identification,mRNA and protein analysis.Compared to Retnlbflox/flox mice,Retnlb-CKO mice exhibited no significant differences in body length,weight,diet,or reproductive capability.There were no differences in the ratios of heart,liver,spleen,lung,kidney,and colon weight to body weight,nor were there morphological differences in various tissues.However,the mRNA expression of tight junction proteins ZO-1,Occlu-din,and Claudin3 in colon tissues of Retnlb-CKO mice was significantly reduced(P<0.01).PAS staining and immunohis-tochemistry revealed a significant decrease in the number of goblet cells and lysozyme-positive cells in the colon tissues of Retnlb-CKO mice(P<0.01).HE staining showed no obvious pathological change in colon tissues of Retnlb-CKO mice.RT-qPCR further demonstrated a significant downregulation of pro-inflammatory factors NLRP3,interleukin-6(IL-6),IL-1β,and tumor necrosis factor-α(TNF-α)in colon tissues(P<0.01),along with significant downregulation of inflamma-tion signaling pathway proteins TLR4,MyD88,and NF-κB(P<0.01).CONCLUSION:A conditional colon epithelial cell Retnlb gene knockout mouse model was successfully constructed and validated.The absence of Retnlb in colon cells led to impaired intestinal barrier function,decreased mRNA expression of pro-inflammatory factors in colon tissue,and downregulation of mRNA expression of inflammatory pathway proteins TLR4,MyD88,and NF-κB.

This study was designed to explore the correlation between alterations in NLRP3 levels and Th17/Treg imbalance in asthmatic mice undergoing epithelial-mesenchymal transition(EMT).A murine model of asthma was established by intraperitoneal injection combined with nebulization of ovalbumin(OVA).Mice were randomly grouped into asthma model group and normal control group.The airway reactivity was detected with non-invasive lung function instrument.Hematoxylin and Eosin(HE)and Masson's trichrome staining were applied to evaluate the histopathological injury of lung tissue and the extent of lung fibrosis;RT-qPCR was applied to detect EMT-related biomarkers(Snail,E-Cadherin,N-Cadherin),the specific transcription factors of T cell subsets(RoRγt,Foxp3)and NLRP3 in lung tissue of mice;Western blot was used to detect the protein expression of E-cadherin,N-Cadherin and NLRP3 in lung tissue of mice.The Th17 and Treg cell populations in the spleen were enumerated via flow cytometry.Furthermore,the expression levels of NLRP3,IL-17 and IL-10 in bronchoalveolar lavage fluid(BALF)were analyzed by Giemsa staining.Compared with the control group,the asthma model group showed higher level of airway resistance,coupled with an obviously decrease in pulmonary ventilation compliance.Pathological alterations in lung tissue were evident,characterized by thickening of the airway epithelium,airway stenosis,infiltration of inflammatory cells,higher expression levels of N-Cadherin and NLRP3 proteins(P<0.05),lower expression level of E-Cadherin(P<0.001)and higher levels of marker genes(Snail and N-Cadherin)in lung tissue.Furthermore,model mice demonstrated higher level of NLRP3 in BALF(P<0.05),higher level of Th17 in spleen,and higher levels of retinoic acid orphan receptor(ROR)-γt mRNA(P<0.05)and Th17-related cytokines(IL-17)(P<0.01).Concurrently,model mice also showed an obviously decrease in the prevalence of Treg cells,Forkhead box Foxp3 mRNA(P<0.001),and Treg-related cytokine IL-10(P<0.05).The results of the Pearson correlation analysis indicated that the level of NLRP3 mRNA was positively correlated the ratio of RoR γt mRNA,but negatively correlated with Foxp3 mRNA in the lung tissue of asthmatic mice.Additionally,NLRP3 in BALF demonstrated a positive correlation with IL-17 and a negative correlation with IL-10.In conclusion,These findings suggest that NLRP3 may trigger bronchial EMT by exacerbating the immune imbalance of Th17/Treg cells.

Objective:To explore the short-term efficacy on 3D printing assisted reconstruction of traumatic digit joint defects using rib and costo-osteochondral autograft.Methods:From August 2022 to July 2023, 7 patients with open digit joint defects had undergone emergency primary debridement and fracture fixation in the Department of Orthopaedics, 988th Hospital of the Joint Logistics Support Force of PLA. Patients with more phalangeal defects that could not be aligned were treated with antibiotic bone cement filling in the emergency surgery. In the second stage surgery, bone cement was removed and transfer of rib cartilage graft was performed to reconstruct the digit joint defect. According to a 1∶1 3D printed hand templates, rib cartilage grafts were crafted to the shape of digit joints, and then spliced together the digit joints and bone defects for fixation. Follow-up X-ray examinations were taken and assessment of the healing status of rib and fractures of phalangeal and metacarpophalangeal bones were carried out according to the Paley fracture healing score. At the outpatient follow-up, assessment of transferred joint movement and evaluation of upper limb function were conducted according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association. Visual Analogue Scale (VAS) pain scores were evaluated from the affected digits and donor sites.Results:After reconstructive surgery, all 7 patients had primary healing of the wounds of hand. One patient had fat liquefaction at the donor site, and the rest had primary donor site healing. One patient received further surgery for extensor tendon repair after rib cartilage grafting due to the digital extensor tendon injury. All 7 patients were included in postoperative follow-up for 6-11 months, with an average of 9 months. All patients had excellent fracture healing according to the Paley fracture healing score. At the final follow-up, the extension and flexion of the digit joints were found at 40°-80° (average 56.2°) for proximal interphalangeal joints (4 patients), and 10° in extension and 85° in flexion for metacarpophalangeal joint (1 patient). The range of motion of the thumb interphalangeal joint (2 patients) was 20°-35° (average 27.5°). Hand function was assessed according to Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association and it was found that 3 patients were in excellent, 3 in good and 1 in fair.Conclusion:This study focused on the treatment of traumatic digit joint defects by transfer of individually crafted rib cartilages in reconstruction of the defected digit joint. It significantly improves the appearance and function of the defected digit joints, especially suitable for the irregular defects of phalangeal bones.
