Based on clinical epidemiological data， it is believed that qi deficiency constitution is closely related to allergic diseases. According to the fundamental principles of traditional Chinese medicine （TCM） constitution theory， the intrinsic connection between qi deficiency constitution and allergic diseases is analyzed from the perspectives of inherited endowment， life process， environmental restriction， and the interplay of form and spirit. This paper discusses the key points of regulating qi deficiency constitution to prevent allergic diseases in three stages， prevention before illness， prevention of disease progression， and prevention of recurrence after recovery. It also distinguishes the treatment directions for regulating qi deficiency constitution to treat allergic diseases based on different disease locations such as the lung， spleen， and kidney. This aims to expand new ideas for the research on qi deficiency constitution and allergic diseases as well as the prevention and treatment of allergic diseases.

ObjectiveTo observe the clinical efficacy and safety of Dizhuo Huayu prescription combined with catgut embedding therapy in patients with nonalcoholic steatohepatitis （NASH） and dyslipidemia and explore the effect of the combined therapy on inflammatory cytokines interleukin （IL）-18 and IL-1β. MethodsA total of 82 patients with NASH and dyslipidemia from the Gastroenterology Department of the First Affiliated Hospital of Henan University of Chinese Medicine were randomly divided into a control group and a treatment group， with 41 patients in each group. The control group received Polyene Polyenylphosphatidylcholine Capsules， while the treatment group received Dizhuo Huayu prescription granules combined with catgut embedding. The treatment duration was 24 weeks for both groups. At weeks 0， 12， and 24， the traditional Chinese medicine （TCM） syndrome score， body mass index （BMI）， liver fat content assessed by Fibroscan （CAP value）， the level of alanine transaminase （ALT）， aspartate aminotransferase （AST）， gamma-glutamyl transferase （GGT）， total cholesterol （TC）， triglyceride （TG）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， and free fatty acid （FFA）， and the expression of inflammatory cytokines IL-18 and IL-1β in serum were observed. Adverse reactions in both groups were recorded. ResultsA comparison of the comprehensive therapeutic effects between the two groups after 24 weeks of treatment revealed that the total effective rate was 62.16% （23/37） in the control group and 85.71% （30/35） in the treatment group， with a statistically significant difference （χ² = 5.14， P<0.05）. At weeks 12 and 24 after treatment， the TCM syndrome score， BMI， CAP value， TC， TG， LDL-C， and FFA were all significantly lower in both groups compared to pre-treatment levels， while the HDL-C level significantly increased （P<0.05）. The effect was better at week 24 （P<0.05） than at week 12 （P<0.05）， and the treatment group showed better outcomes than the control group at weeks 12 and 24 after treatment （P<0.05）. After 24 weeks of treatment， both groups exhibited significant reductions in IL-18 and IL-1β levels （P<0.05）. The treatment group demonstrated superior efficacy compared to the control group after treatment （P<0.05）. Both groups experienced decreases in ALT， AST， and GGT levels after treatment （P<0.05）. However， there were no statistically significant differences between the 12-week and 24-week post-treatment values within each group， nor were there significant differences between the two groups. No significant adverse reactions were observed in both groups. ConclusionThe Dizhuo Huayu prescription combined with catgut embedding therapy is safe and effective in treating patients with NASH and dyslipidemia， exhibiting hepatoprotective， anti-inflammatory， lipid-regulating， and weight-reducing effects.

ObjectiveTo investigate the effect of modified Weijingtang on the pyroptosis of RAW264.7 macrophages via the cysteinyl aspartate-specific protease-1 （Caspase-1）/gasdermin D （GSDMD） pathway. MethodLipopolysaccharide （LPS） was used to induce pyroptosis of RAW264.7 cells. The blank group was treated with the blank serum， and the intervention groups were treated with the sera containing different doses of modified Weijingtang. After 24 h， the viability of cells in different groups was examined by the cell counting kit-8 （CCK-8）. The pyroptosis and morphology of cells in each group were observed by a scanning electron microscope and a phase-contrast microscope， respectively. The mRNA and protein levels of nucleotide-binding oligomerization domain-like receptor protein 3 （NLRP3）， Caspase-1， and GSDMD in each group were determined by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. The levels of interleukin （IL）-18 and IL-1β in each group were measured by enzyme-linked immunosorbent assay. ResultUnder the electron microscope， RAW264.7 cells presented the best morphology and structure in the blank group and obvious pyroptosis and leakage of cell contents in the model （LPS） group. Compared with the model group， the intervention groups showed reduced pyroptosis to varying degrees， and the high-dose group had the closest cell morphology and structure to the blank group. Under the optical microscope， RAW264.7 cells were spherical in the blank group and irregular with protrusions in the model group. Compared with the model group， the intervention groups showed improved cell morphology， and the cell morphology in the group with the dose of 20% was the closest to that in the blank group. The mRNA and protein levels of NLRP3， Caspase-1， and GSDMD in the model group were higher than those in the blank group （P<0.05）. Compared with the model group， each intervention group showed down-regulated expression of the above indicators （P<0.05）. Compared with the blank group， the model group presented elevated levels of IL-18 and IL-1β （P<0.05）， which were lowered in the intervention （10%， 20%） groups （P<0.01）. ConclusionModified Weijingtang inhibits the pyroptosis of macrophages by down-regulating the Caspase-1/GSDMD pathway and reducing the release of proinflammatory cytokines.

OBJECTIVE To extract the-SH active fractions(SHF)from Bubali Cornu(water buffalo horn)and evaluate its an-tipyretic activity.METHODS SHF was extracted from Bubali Cornu by SDS-DTT,and the content of native thiols(-SH)was deter-mined by Ellman reagent method.SHF was identified based on nano LC-MS/MS technology.Evaluation of antipyretic activity of SHF was based on LPS-induced fever rat model.The levels of PGE2,IL-1β,and TNF-α in plasma as well as the levels of cAMP,PGE2,and TNF-α in the hypothalamus were measured by ELISA kits.An untargeted metabolomics approach was used to further investigate the intervention of SHF on plasma metabolites in febrile rats.RESULTS SDS-DTT could effectively extract SHF from Bubali Cornu,in which the main components were type Ⅰ,type Ⅱ keratins and keratin-associated proteins,which were rich in Cys,and the ratio of-SH to protein in SHF was increased about 20 times more than that of traditional decoction.SHF could significantly decrease(P＜0.01)the body temperature which lasted for 4.5 hours.SHF could also significantly decrease the levels of PGE2,IL-1β,TNF-α and cAMP in plasma and hypothalamic.A total of 137 potentially differential metabolites were identified from plasma samples of the control and model groups,of which 31 metabolites could be dialed back after SHF administration,including lysophosphatidic acid,phosphatidyli-nositol,phosphatidic acid,triglycerides,phosphatidylcholine and so on,which were mainly involved in the glycerophospholipid meta-bolic pathway.CONCLUSION SHF has precise antipyretic effect,and the dosage of 1/10 of the aqueous extract can show its com-parable antipyretic effect,which provides the direction and basis for the basic research on the antipyretic efficacy of Bubali Cornu.

Objective:To investigate the relationship between the virulence and the carbapenem resistance phenotype of Klebsiella pneumoniae from blood infection,and to identify carbapenem-resistant and hypervirulent Klebsiella pneumoniae(CR-HVKP)strains.Methods:A total of 192 Klebsiella pneumoniae strains were isolated from blood culture of patients with bloodstream infections from 2016 to 2019,of which 96 isolates were carbapenem-resistant Klebsiella pneumoniae(CRKP)and 96 were carbapenem-sensitive Klebsiella pneumoniae(CSKP).The drug susceptibility was detected by VITEK-2 automatic microbial analyzer;carbapenemase genes,virulence genes and capsule typing were detected by polymerase chain reaction;the high viscosity phenotype of strains was detected by string test,and the genome characteristics of CR-HVKP were detected by whole genome sequencing.Serum killing and biofilm formation test were used to further verify the virulence of CR-HVKP.Results:There were significant differences in drug resistance to common antibiotics,except for minocycline between CSKP and CRKP isolates(all P<0.05).92 out of 96 CRKP isolates carried carbapenemase genes,mainly blaKPC-2.The string tests were positive in 4 isolates of CRKP and 36 isolates of CSKP(P<0.05).The detection rates of virulence genes Kfu,aerobictin,iutA,ybtS,rmpA,magA,allS,and capsule antigen K1 and K2 in CSKP group were significantly higher than those in CRKP group(all P<0.05).One HVKP strain was detected in the CRKP group(CR-HVKP)and 36 HVKP was detected in the CSKP group(P<0.05).The CR-HVKP strain belonged to the MLST412,serotype K57,expressed iutA,entB,mrkD,fimH,and rmpA virulence genes,and showed strong biofilm formation and significantly increased serum resistance.Whole genome sequencing results showed that this CR-HVKP isolate carried blaSHV-145,blaTEM-1,blaCTX-M-3,fosA6,oqxA5,oqxB26,and aac(3)-Ⅱd resistance genes,accompanied by abnormalities in outer membrane protein K(OmpK)35 and OmpK36.Conclusions:The drug resistance of CRKP is significantly higher than that of CSKP,while CRKP carrying fewer virulence genes in both number and types compared to CSKP.A new MLST type of carbapenem-resistant and hypervirulent Klebsiella pneumoniae strain has been detected,which requires clinical awareness and epidemiological monitoring.

Objective:To explore the effects of adenoid hypertrophy on the growth and development of cranio-maxillofacial hard tis-sues in children at different growth stages.Methods:The cephalic lateral images of 232 children aged 4 to 16 years were measured and analyzed by Bjork-Jarabak cephalometric analysis.The patients were divided into 3 groups:CVM 1-2(A),CVM 3-4(B)and CVM 5-6(C)according to cervical vertebral maturation(CVM).Adenoid hypertrophy group and normal group were set up by Adenoi-dal-Nasopharyngeal Ratio(A/N Ratio)of 0.61.A,B and C groups included 28,55 and 23 cases in the subjects with adenoid hyper-trophy,and 12,65 and 49 cases in those of normal controls respectively.T-test was used to explore the difference of growth and devel-opment measurements among different subgroups of the same CVM stage and the change trend of the difference in different CVM sta-ges.Results:Hypertrophic adenoid children's S-Ar,N-Me and S-Ar/Ar-Go were significantly larger in CVM 1-2 subjects(P＜0.05);Ar-Go-Me,N-S-Ar and Ar-Go-N were significantly larger in CVM 5-6 subjects(P＜0.05),while S-Ar-Go decreased significantly(P＜0.05);S-N,Go-Me,S-Go,S-N/Go-Me and Ar-Go/N-Me had no significant differences in the whole stages(P＜0.05).Conclu-sion:Adenoid hypertrophy has great effect on the cranio-maxillofacial growth trend.It induces more posterior position of condyle,tilt-ing back of mandibular ramus,vertical growth and clockwise rotation of the mandible and incline to form class Ⅱ malocclusion.The effects are more prominant in early and late growth and development stages of the children.

Objective:To investigate the correlation between the evidence-based practice competence of undergraduate nursing interns and hospital evidence-based culture, and to provide a reference for the design of evidence-based practice activities in the internship program for undergraduate nursing interns in the future.Methods:From December 2021 to February 2022, the nursing interns in Hunan province of China were selected as subjects, and the evidence-based practice competence scale for nursing interns and the hospital evidence-based practice culture scale were used to investigate the evidence-based practice ability of nursing interns and hospital evidence-based practice culture.

Conclusions:This Consensus is practical and can provide guidance for clinical nursing practice and quality control of plasma exchange in severe autoimmune encephalitis.

BACKGROUND: Long-term remote ischemic conditioning (RIC) has been proven to be beneficial in multiple diseases, such as cerebral and cardiovascular diseases. However, the hyperacute and acute effects of a single RIC stimulus are still not clear. Quantitative proteomic analyses of plasma proteins following RIC application have been conducted in preclinical and clinical studies but exhibit high heterogeneity in results due to wide variations in experimental setups and sampling procedures. Hence, this study aimed to explore the immediate effects of RIC on plasma proteome in healthy young adults to exclude confounding factors of disease entity, such as medications and gender. METHODS: Young healthy male participants were enrolled after a systematic physical examination and 6-month lifestyle observation. Individual RIC sessions included five cycles of alternative ischemia and reperfusion, each lasting for 5 min in bilateral forearms. Blood samples were collected at baseline, 5 min after RIC, and 2 h after RIC, and then samples were processed for proteomic analysis using liquid chromatography-tandem mass spectrometry method. RESULTS: Proteins related to lipid metabolism (e.g., Apolipoprotein F), coagulation factors (hepatocyte growth factor activator preproprotein), members of complement cascades (mannan-binding lectin serine protease 1 isoform 2 precursor), and inflammatory responses (carboxypeptidase N catalytic chain precursor) were differentially altered at their serum levels following the RIC intervention. The most enriched pathways were protein glycosylation and complement/coagulation cascades. CONCLUSIONS One-time RIC stimulus may induce instant cellular responses like anti-inflammation, coagulation, and fibrinolysis balancing, and lipid metabolism regulation which are protective in different perspectives. Protective effects of single RIC in hyperacute and acute phases may be exploited in clinical emergency settings due to apparently beneficial alterations in plasma proteome profile. Furthermore, the beneficial effects of long-term (repeated) RIC interventions in preventing chronic cardiovascular diseases among general populations can also be expected based on our study findings.

Objective:To determine a relationship between ultrasound shear wave elastography (SWE) and pathological lessions of renal tissues in children with chronic kidney disease (CKD).Methods:It was a cross-sectional observational study, involving children admitted to the Department of Pediatrics of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January to December 2021 with definite pathological diagnosis through kidney biopsy. The SWE was used to determine the Young's modulus (elastic modulus) of the cortex and medulla of the upper, middle, and lower poles of the kidney. The renal histopathology was classified or graded. The statistical method was used to analyze the relationship between Young's modulus of the inferior polar cortex (YM cor) and medulla (YM med) of the right kidney and renal pathology. Results:The study included 110 children with definite pathological diagnosis through renal biopsy, aged (10.1±3.4) years old (2-17 years old), with 55 males (50.0%). The body mass index was (20.6±2.4) kg/m 2, and mean arterial pressure was (95±24) mmHg. There were 94 patients (85.4%) with CKD stage 1, 8 patients (7.3%) with CKD stage 2, and 8 patients (7.3%) with CKD stage 3. There was no significant difference of YM cor and YM med in the upper and middle poles of the right kidneys, and YM med in the lower poles of right kidneys in CKD patients with different stages (all P>0.05). Both YM cor [(15.75±3.36) kPa] and YM med [(13.50±2.43) kPa] of CKD stage 3 patients were significantly higher than those of CKD stage 1 patients [(12.94±2.45) kPa, (11.88±2.23) kPa](both P<0.05). There was no significant difference of YM cor and YM med in the lower poles of right kidneys between stage 1 and stage 2 CKD patients (both P>0.05). YM cor[(17.93±3.23) kPa] and YM med [(15.50±1.48) kPa] in patients with crescentic glomerulonephritis were higher than those in patients with focal segmental glomerulosclerosis [(12.71±2.42) kPa, (11.57±2.63) kPa] and mesangial proliferative glomerulonephritis [(12.73±2.04) kPa, (11.48±2.10) kPa](all P<0.05). There was no significant difference of YM cor and YM med between focal segmental glomerulosclerosis and mesangial proliferative glomerulonephritis (both P>0.05). YM cor [(16.30±2.63) kPa] and YM med [(15.54±1.59) kPa] of Lee's Ⅳ grade of IgA nephropathy were higher than those of Lee's Ⅲ grade [(13.32±2.70) kPa, (12.57±2.50) kPa](both P<0.05), while the International Study of Kidney Disease in Children grade of purpura nephritis had no significant correlation with YM cor and YM med (both P>0.05). YM cor [(15.41±2.37) kPa] and YM med [(13.82±2.59) kPa] of interstitial fibrosis/tubular atrophy (T1/T2) group of IgA nephropathy mixed with purpura nephritis were significantly higher than those of T0 group's [(12.99±2.40) kPa, (11.79±2.05) kPa] (both P<0.05). Moreover, crescent formation (C1) group had a higher YM cor [(14.21±2.77) kPa] and YM med [(12.80±2.47) kPa] than those in C0 group [(12.73±2.15) kPa, (11.59±1.97) kPa] (both P<0.05), while YM cor and YM med were unrelated to the mesangial hypercellularity (M), endocapillary cellularity (E), segmental sclerosis or adhesion (S) indicators (all P>0.05). In lupus nephritis patients, YM cor ( r=0.744, P=0.035) and YM med ( r=0.728, P=0.009) were favorably linked with the chronic index, but not with the activity index (both P>0.05). Conclusions:Renal interstitial fibrosis/tubular atrophy and crescentic development are connected with YM cor and YM med at the lower pole of the kidney as measured by SWE. SWE can be used to assess the chronic renal lesions in children with CKD in the early and middle stages. It may develop into a new noninvasive way to assess renal pathology.
