Objective To establish the functional constipated mouse model by compound diphenoxylate, and explore the anti-constipation effect of black garlic polysaccharide. Methods Mouse small intestine ink propulsion experiment and mouse defecation experiment were carried out respectively. The mice in each experiment were randomly divided into blank group, model group, positive group and black garlic polysaccharide （0.25, 0.5, 1 g/kg） groups. Mice in blank group and model group were given distilled water, and in positive group were given lactulose oral solution. Compound diphenoxylate （5 mg/kg） was intragastric administrated after 1 week of administration, and small intestine propulsion experiment and defecation experiment were conducted respectively. Results Compared with model group, intestinal propulsion rate of black garlic polysaccharide groups was significantly increased and first dejection time was significantly shorten, and the number, weight and fecal water content increased significantly at 6 h in middle and high dose groups. Conclusion Black garlic polysaccharide could promote intestinal propelling, shorten defecation time and increase fecal water content.

ObjectiveTo investigate the target proteins directly bound by neochlorogenic acid （NA） and the molecular mechanisms that ameliorate the proliferation and inflammatory response of psoriatic keratinocytes. MethodsM5-induced HaCaT cells were used as a psoriatic keratinocyte proliferation and inflammatory cell model. The synthesized NA probe （NA-P） and NA prodrug were first evaluated for cell viability using a cell proliferation/cell counting kit-8（CCK-8）. The potency of NA and NA-P was evaluated in the safe concentration range， and the effects of 0-100 μmol·L^-1 NA and probe on M5-induced proliferation of HaCaT cells were detected using CCK-8. The effects of 20， 40， 80 μmol·L^-1 NA and 80 μmol·L^-1 NA-P on the expression of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， interleukin-23 （IL-23）， and interleukin-17A （IL-17A） inflammatory factors were detected by enzyme-linked immunosorbent assay （ELISA）， and real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to measure the effects of NA on the mRNA expression of keratin 16 （K16） in HaCaT cells， S100 calcium-binding protein A9 （S100A9）， S100 calcium-binding protein A7 （S100A7）， IL-6， IL-17A， and chemokine 1 （CXCL1）. In vitro fluorescence labeling and competition experiments using NA-P were performed， and target protein angling and analysis using pull-down experiments combined with liquid chromatography-mass spectrometry （Pull-down/LC-MS/MS） were conducted. Target validation was performed using pull-down experiments combined with protein immunoblotting （Pull down-WB）， cellular heat transfer analysis combined with protein immunoblot （CETSA-WB） experiments， and molecular docking. Finally， Real-time PCR was utilized to detect the effects of 20， 40， 80 μmol·L^-1 NA and 80 μmol·L^-1 NA-P on the mRNA expression of IL-1β， nucleotide-binding oligomeric structural domain-like receptor protein 3 （NLRP3）， apoptosis-associated speckled-like protein （ASC）， and cysteine protease-1 （Caspase-1） in HaCaT cells. Protein immunoblot （Western blot） was used to detect the effects of phosphorylated p65 （p-p65）， p65， phosphorylated human nuclear factor-κB inhibitory protein α （p-IκBα）， human nuclear factor κB inhibitory protein α （IκBα）， and heat shock protein 90 （HSP90） expression. ResultsIn the 200 μmol·L^-1 safe concentration range， HaCaT cell proliferation， increased expression of TNF-α， IL-1β， IL-23， and IL-17A inflammatory factors， and increased mRNA expression of K16， S100A9， S100A7， IL-6， IL-17A， and CXCL1 were observed in the M5 group compared with the blank group. Cell proliferation in 5-100 μmol·L^-1 NA and NA-P groups was inhibited， and the expression of TNF-α， IL-1β， IL-23， and IL-17A inflammatory factors was decreased in the NA-L， NA-M， NA-H， and NA-P-H groups. The mRNA expression of K16， S100A9， S100A7， IL-6， IL-17A， and CXCL1 was decreased （P<0.05）. High-confidence targets were screened for HSP90 protein by Pull-down/LC-MS/MS using 200 μmol·L^-1 NA competing with 100 μmol·L^-1 NA-P. Compared with that in the blank group， the mRNA expression of NLRP3， IL-1β， ASC， and Caspase-1， as well as the expression of p-p65/p65， p-IκBα/IκBα， and HSP90 protein， were increased in HaCaT cells in the M5 group （P<0.05）. Compared with that in the M5 group， the mRNA expression of NLRP3， IL-1β， ASC， and Caspase-1 of cells in the NA-L group， the NA-M group， the NA-H group， and the NA-P-H group was decreased （P<0.05）. p-p65/p65 and p-IκBα/IκBα were decreased in the NA-M and NA-H groups （P<0.05）， and there was no change in HSP90 protein. Pull down-WB showed that NA could directly target HSP90 protein， and NA binding to HSP90 protein enhanced its thermal stability. Molecular docking of NA with HSP90 family proteins HSP90AA1， HSP90B1， and HSP90AB1 all resulted in highly stable binding. ConclusionNA can inhibit the proliferation and inflammatory response of psoriatic keratinocytes by a mechanism that may be achieved by targeting HSP90 to modulate the NF-κB/NLRP3 signaling pathway.

ObjectiveTo investigate the objective characteristics of tongue manifestations in patients with coronary heart disease （CHD）. MethodsA total of 315 participants with CHD were recruited in the CHD group， and 211 healthy participants who underwent physical examination were recruited as the healthy control group. In addition， according to the common comorbidities （primary hypertension， carotid atherosclerosis， type 2 diabetes mellitus， fatty liver， hyperlipidaemia， heart failure， and cerebral infarction） in 315 participants with CHD， each comorbidity was classified into a group of comorbidities with that disease and a group of non-comorbidities. Tongue images were captured using a TFDA-1 tongue diagnostic instrument to characterise the tongue body （TB） and tongue coating （TC）， comparing the RGB， HIS， and Lab colour spaces in the chromaticity index （R， red； G， green； B， blue； H， hue； I， intensity； S， saturation； L， lightness； a， red-green axis； b， yellow-blue axis）， the tongue coating thickness index （per-All）， contrast （CON）， angular second moment （ASM）， entropy （ENT）， and mean （MEAN） in texture metrics. ResultsCompared with the healthy control group， the characteristic indexes of tongue body in CHD group showed lower TB-R， TB-G， TB-B， TB-I， TB-L and higher TB-H， TB-b； and the characteristic indexes of tongue coating in CHD group showed lower TC-R， TC-B and higher TC-CON， TC-MEAN， TC-H， TC-b （P＜0.05 or P＜0.01）. Compared with non-combined primary hypertension group， CHD combined primary hypertension group showed higher per-All， TB-G， TB-L， and lower TB-a， TC-a （P＜0.05）； compared with the non-combined carotid atherosclerosis group， CHD combined carotid atherosclerosis group showed higher TB-CON， TB-ENT， TB-MEAN， and lower TB-ASM （P＜0.05 or P＜0.01）； compared with the non-combined type 2 diabetes mellitus group， CHD combined type 2 diabetes mellitus group showed lower per-All and higher TB-H （P＜0.05 or P＜0.01）； compared with the non-combined fatty liver group， CHD combined fatty liver group showed higher TB-CON， TB-MEAN， TB-ENT， and lower TB-ASM and TC-S （P＜0.05 or P＜0.01）； compared with the non-combined hyperlipidaemia group， CHD combined hyperlipidaemia group showed lower TB-S and TB-a （P＜0.05）； compared with non-combined heart failure group， CHD combined heart failure group showed lower TB-R， TB-G， TB-I， TB-L， and higher TB-a （P＜0.05 or P＜0.01）； compared with non-combined cerebral infarction group， CHD combined cerebral infarction group showed higher TC-CON， TC-ENT， TC-MEAN， and lower TC-ASM （P＜0.05 or P＜0.01）. ConclusionCompared to healthy individuals， patients with CHD tend to have darker tongue colours and rougher TC textures. Compared with non-comorbidity participants， those with primary hypertension tended to be lighter tongue colour and thicker tongue coating， those with carotid atherosclerosis had paler tongue body， those with type 2 diabetes mellitus had thinner tongue coating， those with fatty liver disease had paler tongue body and whiter tongue colour， those with hyperlipidaemia and heart failure had paler tongue colour， and those with cerebral infarction had rougher tongue texture.

Objective:To discuss the effect of long-term use of chlorhexidine on the resistance of Enterococcus faecalis(E.faecalis),and to clarify its mechanism.Methods:The standard strain of E.faecalis was repeatedly exposed to chlorhexidine for 10 generations,and the minimum inhibitory concentration(MIC)was recorded at each passage.The bacteria collected from the 10th generation with increased MIC values were designated as the E.faecalis chlorhexidine-resistant strains(E.faecalis-Cs).The growth curves of two strains were drawn;the morphology of two strains were observed by transmission electron microscope;the number of biofilm formation of two strains was detected by crystal violet staining;the bacterial hydrophobicities of two strains were detected by microbial adhesion to hydrocarbons(MATH)method;the expression levels of S-ribosylhomocysteine lyase(LuxS)mRNA in the bacterial biofilms of two strains were detected by real-time fluorescence quantitative PCR(RT-qPCR)method.Results:From the 0th to the 10th generation,the MIC values of E.faecalis were gradually increased.The growth curves of E.faecalis and E.faecalis-Cs showed no significant differences.The transmission electron microscope observation results showed that both E.faecalis and E.faecalis-Cs appeared oval or diplococcal,with intact cell wall structures,smooth edges,and evenly distributed cytoplasm.There were no significant differences in the morphology,size,cell wall thickness,or integrity between two types of bacteria.The crystal violet staining results showed that compared with E.faecalis,the number of biofilm formation of E.faecalis-Cs was significantly increased(P<0.05).The MATH results showed tha the hydrophobicity of E.faecalis-Cs was significantly higher than that of E.faecalis(P<0.05).The RT-qPCR results showed that the expression level of LuxS mRNA in the biofilms of E.faecalis-Cs was significantly higher than that of E.faecalis(P<0.05).Conclusion:E.faecalis develops the resistance after repeated exposure to the chlorhexidine,and the pathogenicity of the resistant strain is enhanced.The high expressin of quorum sensing(QS)system LuxS gene and stronger biofilm forming ability of bacteria may be the potential mechanism for E.faecalis to tolerate the chlorhexidine.

Objective·To further clarify the mechanism of podocyte damage by studying the expression of cartilage oligomeric matrix protein(COMP)in glomerular podocytes and its relationship with podocyte autophagy under high glucose environment.Methods·The gene expression dataset GSE104948 was downloaded from the GENE EXPRESSION OMNIBUS(GEO)database,and differentially expressed genes(DEGs)were obtained via GEO2R.The molecular functions and signaling pathways related to differential genes were summarized.The most correlated key genes(hub genes)were acquired by Weighted Gene Co-Expression Network Analysis(WGCNA)and the protein-protein interaction network(PPI)of DEGs was constructed with STRING database.The enrichment analysis was performed again.Conditionally immortalized mouse podocyte cells were cultured in vitro.After being fully differentiated,they were stimulated with high glucose,and the expressions of COMP,mammalian target of rapamycin(mTOR),microtubule-associated protein 1 light chain3(LC3)and other proteins in podocytes were detected by Western blotting.The shRNA constructed by lentiviral vector was further used to infect podocytes to inhibit the expression of COMP,and the stable cell strains were screened by puromycin.The expression of COMP,mTOR,and LC3 of stable strains were detected by Western blotting,in order to observe the effect of COMP on autophagy.Results·A total of 362 DEGs were filtered for subsequent analysis.Among these DEGs,284 genes were up-regulated and 78 genes were down-regulated.The results of Gene Onotology(GO)term analysis showed that DEGs in diabetic nephropathy(DN)were mainly enriched in cell surface receptor signaling pathway,receptor binding,etc.The main enriched Kyoto Encyclopedia of Genes and Genomes(KEGG)pathways included phosphatidylinositol 3-kinase(PI3K)/protein kinase B(PKB/AKT)signaling pathway,extracellular matrix(ECM)-receptor interaction,etc.Sixty-four hub genes were refined through the intersection of WGCNA and PPI hub genes,and the hub genes with significantly increased or decreased expression were sifted.The hub genes were annotated with KEGG again,and it was found that most of the hub genes were enriched in"ECM-receptor interaction"and"PI3K/AKT signaling pathway".The PI3K/AKT/mTOR signaling pathway is a classic autophagy pathway,and COMP was absolutely overexpressed(logFC>2)in the 64 hub genes,suggesting that it may affect autophagy through this pathway.Western blotting showed that compared with the mannitol control group and the low glucose group,the expression of COMP in podocytes was significantly increased under high glucose stimulation.Compared with the control group,the expression of LC3-Ⅱ in the high glucose group was significantly decreased,indicating that the autophagy initiation of podocytes was inhibited under the high glucose environment.Compared with the negative control,the expression of LC3-Ⅱ in renal podocytes of mice with knockdown of COMP was significantly increased,and the mTOR decreased with the decrease of the expression of COMP,indicating that inhibiting COMP contributed to the recovery of autophagy in podocytes.Conclusion·COMP is highly expressed in DN patients and highly enriched in ECM receptor and PI3K/AKT signaling pathway.Autophagy in mouse renal podocytes is inhibited under high glucose conditions,and the high expression of COMP induced by high glucose may be a key factor in autophagy inhibition.Inhibiting COMP helps to restore autophagy in mouse renal podocytes.

Objective This study aims to analyze the factors influencing benefit finding among cervical cancer patients and their spouses,as well as the interconnections between these factors.The goal is to provide a foundation for developing targeted clinical interventions.Methods Using the convenience sampling method,cervical cancer patients and spouses of 245 pairs who attended or were hospitalized in a tertiary-level hospital in Taiyuan City from October 2022 to July 2023 were selected as study subjects.Data were collected using a general information questionnaire,the Distress Disclosure Index,the Connor-Davidson Resilience Scale,and the Benefit Finding Scale.Univariate analysis,Pearson correlation analysis,and multiple linear regression were employed to scrutinize the data,leading to the establishment of Actor-Partner Interdependence Model.Results Benefit finding scores for cervical cancer patients and their spouses were(65.31±7.94)and(69.87±9.63),respectively.Multiple linear regression revealed that the educational level of patients and their spouses,whether or not they received chemotherapy or radiotherapy,self-disclosure and psychological resilience were the factors that affected patients'benefit finding.Spouse's education level,occupation,self-disclosure,psychological resilience and patients'self-disclosure and psychological resilience were the influencing factors of spouse's benefit finding.The Actor-Partner Interdependence Model analysis indicated that the self-disclosure and psychological resilience of cervical cancer patients positively predicted their own benefit finding and that of their spouses(path coefficients were 0.415,0.501,0.216,and 0.168,respectively,all P＜0.05).However,spouses'self-disclosure and psychological resilience could only positively predict their own benefit finding(path coefficients were 0.188 and 0.254,respectively,all P＜0.05).Conclusion Benefit finding among cervical cancer patients and their spouses is moderate and influenced by various factors.Both self-disclosure and psychological resilience of cervical cancer patients and their spouses have positive subjective effects on their own benefit finding.Healthcare professionals should encourage both parties to engage in healthy interactions about the disease,take steps to increase the level of psychological resilience of both,and ultimately tap into a higher level of benefit finding.

Objective:To investigate the influence of maternal autoimmune diseases and anticoagulants, including low-molecular-weight heparin (LMWH) and aspirin, on the fetal fraction of maternal plasma cell-free DNA of non-invasive prenatal testing (NIPT).Methods:A prospective cohort study was conducted on women with singleton pregnancies receiving NIPT in the Nanjing Drum Tower Hospital from March 2021 to July 2022. NIPT was carried out using a polymerase chain reaction (PCR)-free amplification platform. In this study, four types of maternal autoimmune diseases, which were antiphospholipid syndrome, undifferentiated connective tissue disease, Sj?gren's syndrome, and systemic lupus erythematosus (SLE), and two anticoagulants, LMWH and aspirin, were studied. Univariate and multivariate linear regression models were used to analyze the factors influencing fetal fraction of maternal plasma cell-free DNA.Results:A total of 4 102 singleton pregnant women were enrolled in the prospective cohort, and 3 948 were finally included after excluding the cases with unclear dosing time of LMWH or aspirin, other autoimmune diseases, conceiving through ovulation induction alone, and having true positive or failed NIPT result. There were 96 cases with antiphospholipid syndrome, 35 with undifferentiated connective tissue disease, 34 with Sj?gren's syndrome, and 18 with SLE. A total of 108 patients only received LMWH treatment, 121 only received aspirin treatment, and 113 received both LMWH and aspirin treatment. Univariate linear regression analysis showed that maternal body mass index at blood collection ( B=－0.423), conceived by assisted reproductive technology ( B=－0.803), male fetus ( B=－0.458), undifferentiated connective tissue disease ( B=1.774), and SLE ( B=3.467) had influence on the fetal fraction (all P<0.05). Multivariate linear regression analysis showed that maternal body mass index at blood collection ( B=－0.415), conceived by assisted reproductive technology ( B=－0.585), male fetus ( B=－0.322), SLE ( B=3.347) and undifferentiated connective tissue disease ( B=1.336) were factors influencing fetal fraction (all P<0.05). Conclusions:Maternal use of LMWH or aspirin does not affect fetal fraction when performing NIPT on a PCR-free amplification platform, but undifferentiated connective tissue disease and SLE are the influencing factors. Therefore, pregnant women should be informed before the NIPT that the fetal fraction of maternal plasma cell-free DNA may be affected by maternal autoimmune diseases.

OBJECTIVE To establish a quantitative analysis of multi-components by single marker （QAMS） method for simultaneous determination of 10 ganoderic acids in Ganoderma lucidum.

RSDs of precision， stability （24 h） and reproducibility tests were all lower than 2%. Their average recovery rates were 99.43%， 100.25%， 98.50%， 99.88%， 100.59%， 99.64%， 98.50%， 99.40%， 99.64% and 99.76%， respectively （RSD＜2%， n＝6）. Relative correction factors of ganoderic acid B， ganoderic acid C2， ganoderic acid D， ganoderic acid F， ganoderic acid H， ganoderenic acid A， ganoderenic acid B， ganoderenic acid C and ganoderenic acid D were 1.788 5， 1.288 2， 1.126 4， 1.698 5， 0.885 4， 5.468 1， 4.210 9， 5.780 8， 4.290 3， respectively. Relative errors between the content obtained by QAMS method and external standard method for G. lucidum from different origins were within ±12%. CONCLUSIONS It is feasible that the contents of 10 ganoderic acids are determined simultaneously by QAMS method， using ganoderic acid A as internal reference. This method shows good precision and reproducibility and can be used for the quality control of G. lucidum.

ObjectiveTo investigate the influence of different diagnostic criteria on the short-term prognosis of patients with acute-on-chronic liver failure （ACLF）. MethodsA total of 115 ACLF patients who were hospitalized in Department of Gastroenterology， The Second Affiliated Hospital of Kunming Medical University， from January 2018 to January 2022 were enrolled， and all patients received internal medical treatment combined with artificial liver therapy. According to the guidelines， the patients were divided into CMA guideline group （Diagnostic and treatment guidelines for liver failure by Chinese Medical Association）（n=100）， APASL guideline group （Consensus statements of Asian Pacific Association for the Study of the Liver）（n=94）， and EASL guideline group （Criteria proposed by European Association for the Study of the Liver）（n=36）. The above three guidelines were compared in terms of 90-day mortality rate. A one-way analysis of variance was used for comprision of continuous date between groups； the chi-square test was used for comprision of categorical date between groups. The receiver operating characteristic （ROC） curve of related variables. ResultsThe 90-day mortality rate was 50.0% in the CMA guideline group， 51.1% in the APASL guideline group， and 77.8% in the EASL guideline group， and the EASL guideline group had a significantly higher 90-day mortality rate than the CMA guideline group （χ²=8.351， P=0.004） and the APASL guideline group （χ²=7.650， P=0.006）. EASL guideline had a sensitivity of 22.2% and a specificity of 92.3% in predicting the risk of short-term mortality， with an area under the ROC curve was 0.576. ConclusionACLF patients who meet EASL guideline tend to have a worse short-term prognosis， and this guideline may help to identify patients at a relatively high risk of short-term death.
