OBJECTIVE: To explore the rules of acupoint selection and compatibility of acupuncture and moxibustion in treatment of chronic cough using data mining. METHODS: The ancient and modern medical record cloud platform, and the databases, i.e. CNKI, Wanfang, VIP, EMbase, Web of Science and PubMed, were searched to screen the ancient and modern literature on acupuncture and moxibustion treatment of chronic cough. The prescription database was established for acupuncture and moxibustion treatment of chronic cough, and the analysis conducted on the frequency and use percentage in the aspects of intervention measures, acupoint selection, acupoint distribution, meridian tropism, special points and acupoint combination, as well as the association rules and clustering rules of acupoint selection. The subgroup analysis was performed in accordance with the etiology of chronic cough and intervention measures. RESULTS: A total of 106 articles were included and 158 prescriptions were extracted. The intervention measures were acupuncture, moxibustion, herbal medication and the combination of several measures. The high-frequency acupoints included Feishu (BL13), Zusanli (ST36), Dazhui (GV14), Pishu (BL20), Danzhong (CV17), Shenshu (BL23), Lieque (LU7), Dingchuan (EX-B1), Tiantu (CV22), and Fenglong (ST40). These acupoints are mainly distributed on the back, lumbar region, chest and abdomen. The involved meridians were bladder meridian of foot-taiyang, conception vessel, and lung meridian of hand-taiyin. The special points covered back-shu points, crossing points and five-shu point. Regarding the compatibility of acupoints, the combination of upper and lower points, and the combination of front and back points were predominant in treatment. The analysis of association rules found that the support of Feishu (BL13)→Zusanli (ST36) was the highest; the cluster analysis obtained 8 clusters of acupoints. The acupoint compatibility and overall rules were similar when cough variant asthma (CVA) or the mixed reasons were involved, and the local treatment approach was adopted if the etiology of disease was related to upper airway cough syndrome (UACS) and gastroesophageal reflux cough (GERC). The acupoint selection was similar among different intervention measures. When two kinds of measures were combined in treatment, Feishu (BL13), Pishu (BL20) and Zusanli (ST36) were the most common. CONCLUSION In treatment with acupuncture and moxibustion for chronic cough, the acupoints are selected on the affected local area, depending on syndrome differentiation, and focusing on back-shu points. The main acupoints are Feishu (BL13), Zusanli (ST36), Dazhui (GV14), Pishu (BL20), Danzhong (CV17) and Shenshu (BL23). The combined therapy is dominant with acupuncture, moxibustion and herbal medicine involved.

OBJECTIVES: To investigate the expression of apolipoprotein C1 (APOC1) in papillary thyroid carcinoma (PTC) and its effects on proliferation and apoptosis of PTC cells. METHODS: The expression level of APOC1 in PTC and its impact on prognosis were analyzed using GEPIA 2 and Kaplan-Meier databases. Immunohistochemistry (IHC) and Western blotting were used to detect the expression of APOC1 in PTC and adjacent tissues and in 3 PTC cell lines and normal thyroid Nthyori 3-1 cells. In TPC-1 and BCPAP cells, the effect of Lipofectamine 2000-mediated transfection with APOC1 siRNA or an APOC1-overexpressing plasmid on cell growth and colony formation ability were examined by observing the growth curves and using colony-forming assay. The changes in cell cycle and apoptosis of the transfected cells were analyzed with flow cytometry. RT-qPCR and Western blotting were used to detect the changes in expressions of P21, P27, CDK4, cyclin D1, Bcl-2, Bax, caspase-3 and caspase-9 and the key proteins in the JAK2/STAT3 signaling pathway. RESULTS: APOC1 expression was significantly higher in PTC tissues and the 3 PTC cell lines than in the adjacent tissues and Nthyori 3-1 cells, respectively. In TPC-1 and BCPAP cells, APOC1 knockdown obviously reduced cell proliferative activity, increased the percentage of G0/G1 phase cells, lowered the percentages of S and G2 phase cells, promoted cell apoptosis, and downregulated mRNA and protein expression levels of CDK4, cyclin D1 and Bcl-2 and the protein levels of p-JAK2 and p-STAT3. APOC1 overexpression in the cells produced the opposite effects on cell proliferation, apoptosis, cell cycle and the mRNA and protein expressions. The application of AG490, a JAK2 inhibitor, strongly attenuated APOC1 overexpression-induced activation of the JAK2/STAT3 signaling pathway in BCPAP cells. CONCLUSIONS APOC1 overexpression promotes proliferation and inhibits apoptosis of PTC cells possibly by activating the JAK2/STAT3 signaling pathway and accelerating cell cycle progression.

Objective:To investigate the characteristics of the CD8+T cells infiltration from the 4 sub-types in medulloblastoma(MB),to analyze the relationship between CD8+T cells infiltration and prog-nosis,to study the function of C-X-C motif chemokine ligand 11(CXCL11)and its receptor in CD8+T cells infiltration into tumors and to explore the potential mechanism,and to provide the necessary clinico-pathological basis for exploring the immunotherapy of MB.Methods:In the study,48 clinical MB sam-ples(12 cases in each of 4 subtypes)were selected from the multiple medical center from 2012 to 2019.The transcriptomics analysis for the tumor of 48 clinical samples was conducted on the NanoString Pan-Cancer 10360?Panel(NanoString Technologies).Immunohistochemistry(IHC)staining of formalin-fixed,paraffin-embedded sections from MB was carried out using CD8 primary antibody to analyze diffe-rential quantities of CD8+T cells in the MB four subtypes.Through bioinformatics analysis,the relation-ship between CD8+T cells infiltration and prognosis of the patients and the expression differences of various chemokines in the different subtypes of MB were investigated.The expression of CXCR3 receptor on the surface of CD8+T cells in MB was verified by double immunofluorescence staining,and the under-lying molecular mechanism of CD8+T cells infiltration into the tumor was explored.Results:The charac-teristic index of CD8+T cells in the WNT subtype of MB was relatively high,suggesting that the number of CD8+T cells in the WNT subtype was significantly higher than that in the other three subtypes,which was confirmed by CD8 immunohistochemical staining and Gene Expression Omnibus(GEO)database analysis by using R2 online data analysis platform.And the increase of CD8+T cells infiltration was posi-tively correlated with the patient survival.The expression level of CXCL11 in the WNT subtype MB was significantly higher than that of the other three subtypes.Immunofluorescence staining showed the presence of CXCL11 receptor,CXCR3,on the surface of CD8+T cells,suggesting that the CD8+T cells might be attracted to the MB microenvironment by CXCL11 through CXCR3.Conclusion:The CD8+T cells infiltrate more in the WNT subtype MB than other subtypes.The mechanism may be related to the activation of CXCL11-CXCR3 chemokine system,and the patients with more infiltration of CD8+T cells in tumor have better prognosis.This finding may provide the necessary clinicopathological basis for the regulatory mechanism of CD8+T cells infiltration in MB,and give a new potential therapeutic target for the future immunotherapy of MB.

Objective:To screen the host interaction proteins of the severe fever with thrombocytopenia syndrome virus(SFTSV)nonstructural protein(NSs)by immunoprecipitation combined with mass spectrometry analysis,to discuss the functions,subcellular localization,and biological pathways of these interaction proteins,and to provide the basis for clarifying the replication and pathogenic mechanism of SFTSV.Methods:The eukaryotic expression vectors pSFTSV-NSs-Flag(experimental group)and Flag-CMV-3(negative group)were transfected into the human embryonic kidney 293T cells,and contorl group(no treatment)was set up.The lysates of the cells in various groups were collected,and the expression and localization of SFTSV NSs in the host cells were verified by indirect immunofluorescence and Western blotting methods.The protein lysates were treated with protein A/G and immunoprecipitation was used to enrich host proteins binding to NSs.The captured interaction proteins were initially analyzed by silver staining and Coomassie brilliant blue staining to observe the differential protein bands in various groups;liquid chromatography-tandem mass spectrometry was used to obtain the information of protein sequences;the reliable proteins were retained and searched by UniProt database;Gene Ontology(GO)functional enrichment analysis,IPR,eukaryotic orthologous groups(KOGs)functional annotation,Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis,subcellular localization,and transcription factor(TF)functional annotation were used to determine the subcellular structure,gene functions,and biological processes of the interaction proteins.Results:The immunofluorescence results showed that the SFTSV NSs expressed a single specific band at relative molecular mass 33 000 and was localized in the cytoplasm in a granular inclusion body-like manner.The silver staining and Coomassie brilliant blue staining results showed there were significant differential protein bands between experimental group and negative group.The mass spectrometry results identified 46 potential interaction proteins.The GO functional enrichment analysis,KOGs functional annotation,and KEGG signaling pathway enrichment analysis results showed that the biological pathways related to viral translation,cellular metabolism,and protein transport were enriched with a considerable number of proteins.Eight annotated proteins had intermediate filament domains.The highest percentage of subcellular localization was cytoplasmic proteins,consistent with the NSs localization site.The TF functional annotation analysis results showed one protein from the NF-Y family.Conclusion:The interaction proteins play roles in assisting the proper protein folding,participating in the cribosome translation,and forming the cytoskeleton,which may be involved in antiviral replication.These proteins can be used as candidate proteins for further study on the replication mechanism of SFTSV.

Objective:To explore the clinical effects of a 3D-printed intracranial pressure balancing device in preventing complications after suboccipital craniectomy (DC).Methods:This study is a retrospective cohort analysis. The clinical data of 35 patients who underwent DC at Department of Neurosurgery, Beijing Chaoyang Hospital, Capital Medical University, from September 2020 to September 2023 were reviewed. The cohort included 24 males and 11 females, with an age of (48.7±14.9) years (range:17 to 74 years). Nineteen patients (experimental group) received the intracranial pressure balancing device fixed to the bone defect site post-DC. This device was made using medical-grade dicyanamide resin and was three dimensional printed based on postoperative CT scans of the patients. The remaining 16 patients (control group) did not receive the intracranial pressure balancing device, while other treatments and procedures were consistent with the experimental group. Data were compared using the χ2 test or Fisher′s exact probability method. Results:Out of the 35 patients, 30 cases (85.7%) experienced complications following DC. Specific complications included cerebral infarction in 3 cases (8.6%), intracerebral hemorrhage in 1 case (2.9%), subdural effusion in 27 cases (77.1%) with a median onset of (8.8±6.5) days (range: 1 to 23 days), brain tissue protrusion in 15 cases (42.9%) with a median onset of ( M(IQR)) 7.0 (21.0) days (range:2 to 106 days), and hydrocephalus in 6 cases (17.14%) with a median onset of 34.5 (111.0) days (range: 22 to 136 days). There were no significant differences in the occurrence of complications(all P>0.05). However, there was a significant reduction in the incidence of subdural effusion in the experimental group prior to cranioplasty ( P=0.013). No significant differences were noted in mRS scores between the two groups after cranioplasty ( P>0.05). Conclusions:The intracranial pressure balancing device has the effect of prevention and treatment of subdural effusion. However, it did not significantly improve patient prognosis post-DC, warranting further investigation.

Excavating the quantitative trait locus (QTL) associated with rice cooking quality, analyzing candidate genes, and improving cooking quality-associated traits of rice varieties by genetic breeding can effectively improve the taste of rice. In this study, we used the indica rice HZ, the japonica rice Nekken2 and 120 recombinant inbred lines (RILs) populations constructed from them as experimental materials to measure the gelatinization temperature (GT), gel consistency (GC) and amylose content (AC) of rice at the maturity stage. We combined the high-density genetic map for QTL mapping. A total of 26 QTLs associated with rice cooking quality (1 QTL associated with GT, 13 QTLs associated with GC, and 12 QTLs associated with AC) were detected, among which the highest likelihood of odd (LOD) value reached 30.24. The expression levels of candidate genes in the localization interval were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR), and it was found that the expression levels of six genes were significantly different from that in parents. It was speculated that the high expression of LOC_Os04g20270 and LOC_Os11g40100 may greatly increase the GC of rice, while the high expression of LOC_Os01g04920 and LOC_Os02g17500 and the low expression of LOC_Os03g02650 and LOC_Os05g25840 may reduce the AC. The results lay a molecular foundation for the cultivation of new high-quality rice varieties, and provide important genetic resources for revealing the molecular regulation mechanism of rice cooking quality.

BACKGROUND:Currently,there have been studies on the regulatory mechanism of lncRNA\miRNA\mRNA co-expression network on the occurrence and development of osteoarthritis.Our research group has screened qualified NONHSAT248596.1 and miR-146a-5p through the database in the previous stage,but the corresponding in vivo experiments to verify the above regulatory mechanisms are still lacking. OBJECTIVE:To explore the role of NONHSAT248596.1 in regulating competitive endogenous RNA of miR-146a-5p in cartilage degeneration mediated by stromal cell derived factor type 1/chemokine receptor 4 axis in vivo. METHODS:The models of osteoarthritis were established in 36 New Zealand rabbits by injecting stromal cell derived factor 1 solution into the knee joint of the right hind limb.According to the random number table method,they were divided into four groups.lncRNA group,miRNA group,ceRNA group and control group were injected with lentivirus vector overexpressing NONHSAT248596.1,lentivirus vector overexpressing miR-146a-5p,lentivirus vector overexpressing miR-146a-5p+NONHSAT248596.1 and empty lentivirus vector into the molded knee joint,respectively.At 4,8 and 12 weeks of modeling,cartilage tissues and subchondral bone tissues of the knee joint were taken for relevant detection. RESULTS AND CONCLUSION:Hematoxylin-eosin staining and safranin fast green staining showed different degrees of degeneration in the four groups.At 4 weeks,the cartilage tissue of the lncRNA group showed swelling of chondrocytes,loss of cell polarity,destruction of extracellular matrix,surface erosion,fracture formation and partial or full layer loss of cartilage tissue.The degree of cartilage injury was gradually aggravated with time.The progression of articular cartilage inflammation in the miRNA group was the slowest among the four groups.qRT-PCR showed that at the same time point,mRNA expression levels of NONHSAT248596.1,chemokine receptor 4,matrix metalloproteinase 3,matrix metalloproteinase 9 and matrix metalloproteinase 13 in cartilage tissue of the lncRNA group were higher than those of the other three groups(P＜0.05).The mRNA expression levels of miR-146a-5p,aggrecan and type Ⅱ collagen were lower than those of the other three groups(P＜0.05).The mRNA expression levels of NONHSAT248596.1,chemokine receptor 4,matrix metalloproteinase 3,matrix metalloproteinase 9 and matrix metalloproteinase 13 in the miRNA group were lower than those in the ceRNA group and control group at 8 and 12 weeks after the model construction(P＜0.05).The mRNA expressions of miR-146a-5p,aggrecan and type Ⅱ collagen were higher than those of the ceRNA group and control group(P＜0.05).Western blot assay showed that at the same time point,the expression levels of aggrecan and type Ⅱ collagen in cartilage tissue of the lncRNA group were always lower than those of the other three groups(P＜0.05).The expression levels of aggrecan and type Ⅱ collagen in cartilage tissue of the miRNA group at 8 and 12 weeks after modeling were higher than those of the ceRNA group and control group(P＜0.05).The results showed that miR-146a-5p,as the target of NONHSAT248596.1,could be inhibited by the effect of its ceRNA.After acting on miR-146a-5p,NONHSAT248596.1 regulates the stromal cell derived factor type 1/chemokine receptor 4 axis to affect the expression of matrix metalloprotein,type Ⅱ collagen,and aggrecan in osteoarthritis chondrocytes,resulting in the degradation of extracellular matrix and the loss of proteoglycan.

Objective:To investigate the effect and mechanism of the V-set and immunoglobulin domain-containing 4 ( VSIG4 ) gene mutation on the function of microglia in retinitis pigmentosa (RP). Methods:Localization of VSIG4 in the retina was detected by immunofluorescence.HMC3 cells (human microglial cells) were transfected with wild-type (Len-WT) VSIG4 gene, mutant type (Len-Mut) VSIG4 gene and empty vector virus (Len-Cont) and stimulated by the presence or absence of lipopolysaccharide (LPS), then divided into control group, LPS-Len-Mut group, LPS-Len-WT group, LPS-Len-Cont group, Len-Mut group, Len-WT group and Len-Cont group.The mRNA expression levels of the inflammatory factors interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were detected by real-time fluorescence quantitative PCR.Protein expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase 1 (HO-1), glutathione peroxidase 4 (GPX4), nuclear transcription factor-κB (NF-κB) p65 subunit (P65), and phosphorylated P65 (PP65) were detected by Western blot.Cell phagocytic function was detected by phagocytosis assay.Cell migration ability was detected by cell scratch and transwell migration assay.LPS- stimulated HMC3 cells were co-cultured with 661W cells (mouse retinal photoreceptor cells), and the expression levels of B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X (Bax) proteins of the cells were detected by Western blot.The number of apoptotic cells was determined by apoptosis assay. Results:VSIG4 was localized to microglia in mouse retina.The real-time fluorescence quantitative PCR results showed that compared with LPS-Len-WT group, the relative expression levels of IL-1β and TNF-α mRNA in HMC3 cells were significantly increased in LPS-Len-Mut group (both at P<0.05).The Western blot results showed that compared with LPS- Len-WT group, the protein expression levels of Nrf2, HO-1, and GPX4 in HMC3 cells were significantly reduced in LPS-Len-Mut group, and the PP65/P65 ratio was significantly increased (all at P<0.05).The phagocytic experiment results showed that the phagocytic rates of HMC3 cells in Len-Cont group, LPS-Len-Cont group, LPS-Len-WT group, and LPS-Len-Mut group were (35.67±3.22)%, (63.67±10.07)%, (84.00±3.46)%, and (64.67±2.31)%, respectively, showing a statistically significant difference ( F=59.06, P<0.001).Compared with LPS-Len-WT group, the phagocytic rate of HMC3 cells was significantly reduced in LPS-Len-Mut group ( P<0.05).The results of cell scratch and transwell migration assay showed that compared with LPS-Len-WT group, the migration rate of HMC3 cells at 24 and 48 hours and the number of invading cells per unit area at 24 hours were significantly reduced in LPS-Len-Mut group (all at P<0.05).Compared with LPS-Len-WT group, the expression ratio of Bax/Bcl-2 protein and the number of cell apoptosis were significantly increased in the LPS-Len-Mut group under the co-culture system (both at P<0.05). Conclusions:VSIG4 is localized to mouse retinal microglia.When the VSIG4 gene in RP mutates, HMC3 cells under LPS stimulation exhibit a series of changes, including activation of the NF-κB signaling pathway, decreased activation of the Nrf2/HO-1 signaling pathway, increased secretion of inflammatory cytokines, reduced phagocytic and migratory abilities, and increased cell apoptosis in co-culture systems.

Objective:To explore the short-term and long-term effects of pregnancy with aortic dissection (AD) on newborns.Methods:In this retrospective cohort study, 31 live births of pregnant women with AD admitted to Beijing Anzhen Hospital, Capital Medical University from June 2010 to June 2022 were selected as the AD group.Among them, 19 preterm births were in the preterm AD group.Additionally, 100 neonates delivered by pregnant women without pregnancy complications were selected as the normal control group, and 50 preterm infants delivered by pregnant women without pregnancy complications were selected as the preterm control group during the same period.The differences between the AD group and the normal control group, and between the preterm AD group and the preterm control group were compared using the independent samples t-test, Chi-square test, and Fisher′s exact test.Patients in the AD group were followed up for 5 years.
