OBJECTIVE: To observe the clinical efficacy of thread-embedding at the combined lower he-sea and front-mu points for functional constipation with intestinal excess heat. METHODS: A total of 80 patients with functional constipation of intestinal excess heat were randomly divided into a thread-embedding group (40 cases, 2 cases dropped out) and a Chinese patent medication group (40 cases, 1 case dropped out). Based on the theory of combined lower he-sea and front-mu points for diseases of fu organs, Zhongwan (CV12), Guanyuan (CV4) and bilateral Zusanli (ST36), Shangjuxu (ST37), Tianshu (ST25), Xiajuxu (ST39) were selected and thread-embedding therapy was delivered in the thread-embedding group, once a week. Maren Runchang pill was given orally in the Chinese patent medication group, 6-12 g each time, twice a day. Both groups were treated for 4 weeks. Before and after treatment, the scores of constipation assessment scale (CAS), Bristol stool form scale (BSFS), patient-assessment of constipation quality of life (PAC-QOL) and TCM syndrome were observed, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: After treatment, the CAS scores and the TCM syndrome scores were decreased compared with those before treatment (P<0.05), while the BSFS scores were increased compared with those before treatment (P<0.05) in the two groups; the total scores, as well as the physical discomfort and psychosocial discomfort scores of PAC-QOL were decreased compared with those before treatment (P<0.05) in the two groups, the worry and anxiety, and the satisfaction scores of PAC-QOL were decreased compared with those before treatment (P<0.05) in the thread-embedding group. After treatment, the CAS score, the total score and item-scores of PAC-QOL, as well as the TCM syndrome score in the thread-embedding group were lower than those in the Chinese patent medication group (P<0.05). The total effective rate was 78.9% (30/38) in the thread-embedding group, which was higher than 56.4% (22/39) in the Chinese patent medication group (P<0.05). CONCLUSION Thread-embedding at the combined lower he-sea and front-mu points can effectively treat functional constipation with intestinal excess heat and improve quality of life.

OBJECTIVES: The risk factors and role of mother‒child gut microbiota in pediatric inflammatory bowel disease (PIBD) remain unclear. We aimed to explore the clinical risk factors associated with PIBD, analyze the characteristics of gut microbiota of children and their mothers, and examine the correlation of the microbial composition in mother‒child pairs. METHODS: We conducted a case-control study including children with PIBD and their mothers as the case group, as well as healthy children and their mothers as the control group. Questionnaires were used to collect information such as family illness history and maternal and early-life events. Fecal samples were collected from the children and mothers for microbiota 16S ribosomal RNA (rRNA) sequencing to analyze the composition and its potential association with PIBD. RESULTS: A total of 54 pairs of cases and 122 pairs of controls were recruited. A family history of autoimmune disease and antibiotic use during pregnancy were associated with an increased risk of PIBD, and a higher education level of the father was associated with a decreased risk of PIBD. Children with PIBD and mothers exhibited different gut microbiota compared to healthy children and mothers. Similarities were observed in the gut microbiota of mothers and children in the same groups. Some bacterial biomarkers of mothers discovered in this study had the power to predict PIBD in their offspring. CONCLUSIONS PIBD is influenced by maternal risk factors and has unique gut microbiota characteristics. The mother‒child gut microbiota is closely related, suggesting the transmission and influence of the gut microbiota between mothers and children. This study highlights the potential pathogenesis of PIBD and provides a basis for developing targeted interventions.

Objective:To analyze plaque characteristics of non-culprit coronary lesions with cholesterol crystals in patients with acute myocardial infarction(AMI) by using optical coherence tomography(OCT). We also investigated the potential association between cholesterol crystals with plaque rupture and healed plaque at non-culprit segment.Methods:This study was a retrospective cohort study. Between January 2017 and December 2017, patients with AMI who underwent 3-vessel OCT imaging were included in this study. Patients were divided into two groups according to the presence or absence of cholesterol crystals at the non-culprit lesions. All patients underwent coronary angiography and OCT examination, and non-culprit plaque characteristics were compared between the two groups. The generalized estimating equation log-binomial multirariate regression model was used to assess the relationship between non-culprit lesions with cholesterol crystals and plaque rupture and plaque healing. The follow-up data collection ended in October 2023. Kaplan-Meier survival curves were plotted, and log-rank tests were used to compare the cumulative incidence of major adverse cardiovascular events between the two groups.Results:A total of 173 AMI patients were included (aged (56.8±11.6) years; 124 men (71.7%)). Among 710 non-culprit lesions identified by OCT, there were 102 (14.4%) in cholesterol crystals group and 608 (85.6%) in non-cholesterol crystals group. Compared with non-culprit lesions without cholesterol crystals, those with cholesterol crystals had smaller minimum lumen diameter, severer diameter stenosis, and longer lesion length (all P<0.01). The prevalence of plaque rupture (17.6% (18/102) vs. 4.9% (30/608), P=0.001) and thin-cap fibroatheroma (31.4% (32/102) vs. 11.5% (70/608), P<0.01) was higher in the cholesterol crystals groups than in the non-cholesterol crystals group. In addition, vulnerable plaque characteristics such as (44.1% (45/102) vs. 25.8% (157/608), P<0.01), macrophages were more frequently observed in non-culprit lesions with cholesterol crystals. The generalized estimating equation log-binomial multivariate regression analyses showed that non-culprit cholesterol crystals were positively correlated with healed plaque ( OR=1.583, 95% CI: 1.004-2.495, P=0.048). Conversely, cholesterol crystals were not associated with plaque rupture ( OR=1.632, 95% CI: 0.745-3.576, P=0.221). The follow-up time was 2 142 (1 880, 2 198) days. Non-culprit cholesterol crystals were not related to the major adverse cardiovascular events in patients with AMI (log-rank P=0.558). Conclusions:Among AMI patients, non-culprit lesions with cholesterol crystals presented with severer luminal stenosis and increased plaque vulnerability. The presence of non-culprit cholesterol crystals was associated with rather than plaque rupture.

Objective:To describe the characteristics, etiology and patterns of outpatients and inpatients patients with moderate or severe valvular heart disease (VHD).Methods:This is a cross-sectional study. Outpatients and inpatients with moderate or severe VHD who underwent transthoracic echocardiography for first examination from 1 st January 2001 to 1 st January 2020 in Southwest Hospital, Army Medical University were enrolled. Data were collected from medical records and big data platform of Southwest Hospital. Characteristics of age and gender, etiology and types of VHD were descriptively analysed. Results:A total of 68 354 patients with moderate or severe VHD were enrolled. The age was 63 (50, 72) years. And 35 706 (52.24%) patients were female. (1) Age characteristics: There was similar age trend between male and female patients with moderate or severe VHD. The number of patients increased firstly and then decreased and reached its peak in the age group of 65-69 years old. The peak age of mitral stenosis patients was 45-49 years, which was earlier than that of whole patients with moderate or severe VHD. The median age of patients with bicuspid aortic valve was 42 years. (2) Gender characteristics: The proportion of tricuspid regurgitation, pulmonary regurgitation, mitral regurgitation, mitral stenosis and valve surgery in female patients with moderate or severe VHD were higher than those in male patients. The proportion of aortic regurgitation, aortic stenosis and bicuspid aortic valve in male patients with moderate or severe VHD were significantly higher than those in female patients (all P<0.05). (3) Etiology: The proportion of rheumatic VHD was 13.07% (8 934/68 354), which was higher than that of degenerative VHD (0.67% (458/68 354)). (4) Types of VHD: Tricuspid regurgitation made contribution to the largest proportion with 60.72% (41 503/68 354), followed by mitral regurgitation, aortic regurgitation, mitral stenosis, pulmonary regurgitation and aortic stenosis. Conclusions:There are certain regional characteristics in the prevalence of moderate or severe VHD in southwest China, suggesting different attention should be paid on the whole process of refined management of moderate or severe VHD.

Aim To explore the mechanism of oxidized lipoprotein(a)(oxLp(a))inducing pyroptosis of vascu-lar endothelial cells.Methods After incubating human umbilical vein endothelial cells(HUVEC)with 100 mg/L ox-Lp(a)for 24 hours,Western blot and RT-qPCR was used to detect pyroptosis related proteins,pro-inflammatory cytokines,mitochondrial related proteins NRF1,NRF2,PGC-1α and mitochondrial gene cytochrome b(CYTB),ELISA was used to detect the levels of inflammatory factors,scanning electron microscopy was used to detect cell membrane rup-ture,transmission electron microscopy was used to detect mitochondrial morphology,Hoechst33342/PI staining was used to detect cell apoptosis,MitoSOX probe was used to detect mitochondrial reactive oxygen species(mtROS),Flu-4AM probe was used to detect calcium ions,JC-1 probe was used to detect mitochondrial membrane potential(MMP),and Calcein AM staining was used to detect mitochondrial permeability transition pore(mPTP).Transfecting HUVEC with CYTB overexpressing lentivirus and analyzing its effects on oxLp(a)induced pyroptosis and mitochondrial function.Results After treatment with oxLp(a),the expression of NLRP3,pro-Caspase-1,Caspase-1,GSDMD and GSDMD-N proteins re-lated to pyroptosis were significantly increased(P＜0.05);the protein and mRNA levels of CYTB and pro-inflammatory cy-tokine IL-1β,IL-18 were significantly increased(P＜0.05).Small pores appeared on the cell membrane,the percentage of PI stained positive cells significantly increased(P＜0.05).OxLp(a)significantly inhibited the expression of mito-chondrial related proteins NRF1,NRF2 and PGC-1α,and the expression of mitochondrial gene CYTB,promoted an in-crease in mtROS generation,Ca2+overload,a decrease in ATP levels,a decrease in MMP,an increase in mPTP values,and abnormal mitochondrial morphology.After transfection with pHelper 2.0 lentivirus vector overexpressing CYTB,it was found that oxLp(a)induced HUVEC pyroptosis and mitochondrial morphological and functional abnormalities were par-tially reversed by overexpression of CYTB.Conclusion oxLp(a)promotes mitochondrial morphological and functional abnormalities and induces HUVEC pyroptosis by downregulating CYTB.

The transition from adolescent to adult increases the risk of post-operative related complications for adolescent kidney transplant recipients, and inadequate preparation for the transition can lead to low adherence to immunosuppressive medications and low appointment rates. Therefore, improving the quality of transitional care is the key to reduce the complication rate and readmission rate of adolescent kidney transplant recipients. This article elaborates on the concept of the transitional period from adolescence to adulthood in kidney transplant recipients, the timing and influencing factors of transitional care, transitional preparation assessment tools, and intervention measures, aiming to provide reference for the standardized transitional care of adolescent kidney transplant recipients in China in the future.

Objective:To investigate the clinical significance of graft-versus host disease (GVHD)accompanied with new T-cell receptor (TCR) genes clonal rearrangement after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:The clinical data of 2 patients admitted to People's Hospital of Henan University from December 2018 to March 2020 who developed GVHD after allo-HSCT accompanied with TCR genes clonal rearrangement were retrospectively analyzed, and the related literatures were reviewed.Results:Patient 1 was diagnosed with peripheral T-cell lymphoma non-specific type (PTCL-NOS), and then developed severe acute GVHD (aGVHD) after identical sibling allo-HSCT, and gradually developed liver chronic GVHD (cGVHD), skin cGVHD and new TCR genes clonal rearrangement. Patient 2 was diagnosed with acute myeloid leukemia (AML)-M 4, and severe aGVHD, hepatic cGVHD, and clonal rearrangement of TCR genes were gradually detected after identical sibling allo-HSCT. Conclusions:The TCR genes clonal rearrangement after allo-HSCT is not necessarily suggestive of tumors, and it may be related to lymphocyte development disorder caused by GVHD, so the comprehensive judgement should be carefully made.

Objective To investigate the role of low dose esketamine in pretreated limb ischemia-reperfusion inju-ry.Methods The rats were divided into sham-operated group(Sham group),ischemia-reperfusion group(I/R group,3 h of ischemia and 2 h of reperfusion),esketamine group(ESK group,ip,5 mg/kg).The plasma con-centrations of creatine kinase(CK)and lactate dehydrogenase(LDH)were measured.The wet/dry weight ratio of skeletal muscle was immediately detected.The gastrocnemius muscle was harvested and the level of malondial-dehyde(MDA)and superoxide dismutase(SOD)was detected by colorimetric assay.The expression of nuclear factor erythroid 2-related factor 2(Nrf2)and heme oxygenase-1(HO-1)were detected by Western blot and im-munohistochemical staining.Results Compared with Sham group,the index of wet/dry weight ratio,MDA,CK,LDH,Nrf2 and HO-1 were all increased,but SOD was decreased in I/R group(P＜0.05).Compared with I/R group,the index of wet/dry weight ratio,MDA,CK and LDH were significantly lower,but SOD and Nrf2 and HO-1 were significantly higher in ESK group(P＜0.05).Conclusions ESK may increase Nrf2 in the nucleus,thereby increase the HO-1 protein as an antioxidant agent.

Herpes simplex virus encephalitis (HSE) is a common form of viral encephalitis, often with a single-phase course. A case of HSE with abnormal mental behavior as the main manifestation, admitted in Peking University Shenzhen Hospital in Octorber 2020, which improved after sufficient antiviral treatment was reported. After 2 months, abnormal mental behavior with memory deterioration recurred. It was considered as anti-N-methyl-D-aspartate receptor antibody combined with anti-glutamic decarboxylase antibody double-positive encephalitis, and improved after rituximab treatment. At present, there is no clinical report of such double antibody positive autoimmune encephalitis secondary to HSE. The purpose of this case report is to raise clinician awareness of post-HSE autoimmune encephalitis.

Glioma is a primary aggressive brain tumor with high recurrence rate. The poor efficiency of chemotherapeutic drugs crossing the blood‒brain barrier (BBB) is well-known as one of the main challenges for anti-glioma therapy. Moreover, massive infiltrated tumor-associated macrophages (TAMs) in glioma further thwart the drug efficacy. Herein, a therapeutic nanosystem (SPP-ARV-825) is constructed by incorporating the BRD4-degrading proteolytic targeting chimera (PROTAC) ARV-825 into the complex micelle (SPP) composed of substance P (SP) peptide-modified poly(ethylene glycol)-poly(d,l-lactic acid)(SP-PEG-PDLLA) and methoxy poly(ethylene glycol)-poly(d,l-lactic acid) (mPEG-PDLLA, PP), which could penetrate BBB and target brain tumor. Subsequently, released drug engenders antitumor effect via attenuating cells proliferation, inducing cells apoptosis and suppressing M2 macrophages polarization through the inhibition of IRF4 promoter transcription and phosphorylation of STAT6, STAT3 and AKT. Taken together, our work demonstrates the versatile role and therapeutic efficacy of SPP-ARV-825 micelle against glioma, which may provide a novel strategy for glioma therapy in future.
