The Effect of Nebulized Budesonide Inhalation in Treating Children with Asthma and its Influence on Immune Indexes

Objective:To explore and analyze the effect of nebulized budesonide inhalation on children with asthma and its influence on immune indexes.Methods:300 children who were with asthma admitted to the Pediatric Respiratory Department of our hospital from January 2021 to January 2023 were selected as the research subjects.The patients were divided into a nebulization group(n=150)and a reference group(n=150)by drawing lots.The nebulization group received routine treatment along with budesonide nebulization inhalation therapy,while the reference group only received routine treatment.The treatment effect,the immune indicators,the time taken for the disappearance of symptoms,and the pulmonary function indicators of both groups were compared.Results:The total efficacy of treatment received in the nebulization group was significantly higher than that in the reference group(P<0.05).Before treatment,there was no statistically significant difference in the CD4^(+),CD8^(+),CD4^(+)/CD8^(+),between the two groups(P>0.05);after treatment,the nebulization group’s CD4^(+),CD8^(+),CD4^(+)/CD8^(+)and other immune indicators were significantly better than the reference group(P<0.05).The time taken for the disappearance of symptoms like wheezing,coughing,crackles,shortness of breath,and other symptoms in the nebulization group was significantly shorter than in the reference group(P<0.05).Before treatment,there was no statistically significant difference in the pulmonary function indexes such as FEV1,PEF,and FVC between the two groups(P>0.05);after treatment,the pulmonary function indexes of the patients in the nebulization group were significantly better than those in the reference group(P<0.05).Conclusion:Nebulized budesonide inhalation therapy has shown significant efficacy in the treatment of pediatric asthma,with notable improvements in immune indicators.Therefore,it is worthy of recommendation and further promotion.

Correlation between preoperative systemic immune inflammation index, nutritional risk index, and prognosis of radical resection of liver cancer

BACKGROUND Radical surgery is the most commonly used treatment for hepatocellular carcinoma(HCC).However,the surgical effect remains not ideal,and prognostic evaluation is insufficient.Furthermore,clinical intervention is rife with uncertainty and not conducive to prolonging patient survival.AIM To explore correlations between the systemic immune inflammatory index(SII)and geriatric nutritional risk index(GNRI)and HCC operation prognosis.METHODS This retrospective study included and collected follow up data from 100 HCC.Kaplan–Meier survival curves were used to analyze the correlation between SII and GNRI scores and survival.SII and GNRI were calculated as follows:SII=neutrophil count×platelet count/lymphocyte count;GNRI=[1.489×albumin(g/L)+41.7×actual weight/ideal weight].We analyzed the predictive efficacy of the SII and GNRI in HCC patients using receiver operating characteristic(ROC)curves,and the relationships between the SII,GNRI,and survival rate using Kaplan–Meier survival curves.Cox regression analysis was utilized to analyze independent risk factors influencing prognosis.RESULTS After 1 year of follow-up,24 patients died and 76 survived.The area under the curve(AUC),sensitivity,specificity,and the optimal cutoff value of SII were 0.728(95%confidence interval:0.600-0.856),79.2%,63.2%,and 309.14,respectively.According to ROC curve analysis results for predicting postoperative death in HCC patients,the AUC of SII and GNRI combination was higher than that of SII or GNRI alone,and SII was higher than that of GNRI(P<0.05).The proportion of advanced differentiated tumors,tumor maximum diameter(5–10 cm,>10 cm),lymph node metastasis,and TNM stage III-IV in patients with SII>309.14 was higher than that in patients with SII≤309.14(P<0.05).The proportion of patients aged>70 years was higher in patients with GNRI≤98 than that in patients with GNRI>98(P<0.05).The 1-year survival rate of the SII>309.14 group(compared with the SII≤309.14 group)and GNRI≤98 group(compared with the GNRI>98 group)was lower(P<0.05).CONCLUSION The prognosis after radical resection of HCC is related to the SII and GNRI and poor in high SII or low GNRI patients.

Prognostic impact of preoperative nutritional and immune inflammatory parameters on liver cancer

The immune response to tissue damage or infection involves inflammation,a multifaceted biological process distinguished by immune cell activation,mediator secretion,and immune cell recruitment to the site of injury.Several blood-based immune-inflammatory biomarkers with prognostic significance in malignancies have been identified.In this issue of the World Journal of Gastrointestinal Surgery,they examined the prognosis of liver cancer radical resection in relation to pre-operative systemic immune-inflammation and nutritional risk indices.Comparing older and younger individuals often reveals compromised nutritional and immu-nological statuses in the former.Therefore,performing preoperative evaluations of the nutritional status and immunity in geriatric patients is critical.In addition to being a primary treatment modality,radical resection is associated with a sig-nificant mortality rate following surgery.Insufficient dietary consump-tion and an elevated metabolic rate within tumor cells contribute to the increased proba-bility of malnutrition associated with the ailment,consequently leading to a sub-stantial deterioration in prognosis.Recent studies,reinforce the importance of nu-tritional and immune-inflammatory biomarkers.Prior to surgical intervention,geriatric nutritional risk and systemic immune-inflammatory indices should be prioritized,particularly in older patients with malignant diseases.

Association between the Lung Immune Prognostic Index and mortality in patients with idiopathic inflammatory myopathy-associated interstitial lung disease

Objective:To explore the association between the Lung Immune Prognostic Index(LIPI)and 1-year all-cause mortality in patients with idiopathic inflammatory myopathy related interstitial lung disease(IIM-ILD).Methods:Patients who were diagnosed with IIM-ILD at West China Hospital,Sichuan University from January 2008 to December 2021 were retrospectively included and categorized into three groups based on LIPI.Univariable and multivariable Cox proportional hazards models were conducted to explore potential association between the LIPI and patients'mortality.Results:A total of 1116 patients were screened,and 830 were included in this study.The multivariable Cox analysis showed that,compared with patients with poor LIPI,the hazard ratio(HR)for all-cause 1-year mortality was 0.22(95%CI 0.05-0.93,P=0.04)for patients in the good LIPI group(LDH<250 IU/L and dNLR<3).After excluding patients lost to follow-up within one year,a similar result was found for LIPI(HR 0.20,95%CI 0.05-0.86;P=0.03).Conclusions:Good LIPI was independently associated with decreased risk of all-cause 1-year mortality in patients with IIM-ILD.This easy-to-obtain index might be served as a potential marker for assessing the prognosis of IIM-ILD.

Influences of immersion bathing in Bacillus velezensis DY-6 on growth performance,non-specific immune enzyme activities and gut microbiota of Apostichopus japonicus

In this study, the influences of immersion bathing in different concentrations of Bacillus velezensis DY-6 on the body weight gain rate and non-specific immune enzyme activities of the coelom fluid of sea cucumber (Apostichopus japonicus) were determined in order to obtain the optimum bacterial concentration. The gut microbiota change in A. japonicus was then analyzed through high-throughput sequencing during the immersion bathing in B. velezensis DY-6 at the optimum concentration for 49 d. The results illustrate that the body weight growth rate of all bathing groups was higher than that of the control. The highest growth rate (25.3%) was achieved when the bacterial concentration was 1×10^3 CFU/mL. The activities of non-specific immune enzymes (ACP, AKP, SOD and LZM) of all bathing groups increased, and the activities of the enzymes of groups bathed with the bacterium at 1×10^3 and 1×10^4 CFU/mL reached the highest on day 21 and day 28. Taking the growth rate and economic cost into consideration, the optimum concentration of B. velezensis DY-6 was 1×10^3 CFU/mL. The influences of immersion bathing in B. velezensis DY-6 at 1×10^3 CFU/mL on the gut microbiota of A. japonicus were then evaluated through 16S rDNA sequencing analysis. Results showed that the gut microbiota changed with the addition of B. velezensis DY-6, and the richness and diversity of the gut microbiota peaked twice on day 14 and day 21, respectively. In association with the non-specific immune enzyme activities and if day 28 was selected as the dividing point, the community structure of the gut microbiota could be obviously divided into two types. The correlation analysis revealed that the non-specific immune enzyme activities were correlated significantly to some gut bacteria (in the phyla Firmicutes, Proteobacteria, and Bacteroidetes) after immersion bathing in B. velezensis DY-6. Our findings will provide the theoretical foundation for probiotic application in sea cucumber farming.

Effect of Dietary Alanyl-glutamine Supplementation on Growth Performance, Development of Intestinal Tract, Antioxidant Status and Plasma Non-specific Immunity of Young Mirror Carp(Cyprinus carpio L.)

Exogenous alanyl-glutamine（Aln-Gln） was evaluated for its effects on growth performance, intestinal structure and function, antioxidant status and non-specific immunity of young carp（Cyprinus carpio L.）. Six diets supplemented with 0, 2.5, 5.0, 7.5, 10.0, or 15.0 g · kg-1 of Aln-Gln were fed to fish for 12 weeks. Supplementation with 7.5, 10.0, or 15.0 g · kg-1 of Aln-Gln significantly increased weight gain rate（WGR）, protein efficiency ratio（PER）, but feed conservation rate（FCR） and survival were not affected（P〉0.05）. The intestinal fold height and number, digestive enzyme, Na＋, K＋-ATPase activities was found to be significantly high（P〈0.05） with increasing dietary Aln-Gln supplementation up to 7.5 g · kg-1, but there were no significant differences for Aln-Gln supplementation from 7.5 to 15.0 g · kg-1. The glutathione peroxidase（GPX） activity, glutathione（GSH）, superoxide dismutase（SOD） activity increased and malondialdehyde（MDA） levels decreased significantly（P〈0.05） in the intestine, hepatopancreas, plasma and muscles. The plasma complement-3（C3） and complement-4（C4） levels were significantly（P〈0.05） improved at 5.0 g · kg-1 level and decreased when over 7.5 g · kg-1. The plasma lysozyme（LSZ） activity increased significantly（P〈0.05） at 7.5, 10.0, or 15.0 g · kg-1 level. In summary, the results showed that Aln-Gln improved growth performance, development and function of the intestine, the activity of the antioxidant defense system and the plasma non-specific immunity of the carps. The optimal Aln-Gln level was 8.24 g · kg-1 diet for WGR based on broken-line regression model analysis.

Effects of Size Grading on Growth and Non-Specific Immunity Factors of the Shrimp Litopenaeus vannamei Boone

The study aims to determine the effects of graded farming on growth performance and non-specific immunity factors of shrimp Litopenaeus vannamei Boone. Three size groups of shrimp, i.e., the small size group [Gs, with an average body length （BL） of （3.04 ± 0.36） cm and body weight （BW） （0.412± 0.35） g], the large group [GL, with a BL of （4.29±0.55） cm and BW of （1.098 ±0.42） g], and the ungraded group [Gm, with a BL of （3.47±0.81） cm and BW of （0.611 ±0.79） g], were reared under the same conditions for 8 wk. Growth performance and non- specific immunity factors were measured. The results showed that BW gain, biomass gain and the specific growth rate of body length （SGRL） were significantly influenced by size grading （one-way ANOVA, P 〈 0.05）. The peroxidase （POD） and antibacterial （Ua） activities of GL were lower than those of G. Superoxide dismutase （SOD） and lysozyme （U1） activities of Gm were lower than those of G. No significant difference （P = 0.121 〉 0.05） was found on phenoloxidase （PO） activity among the three size groups. Synthetically, size grading could enhance growth and rearing efficiency, and did not have a significant influence on the immunity of L. vannamei Boone. Therefore, graded fanning in L. vannamei Boone was feasible in the culture practice.

Systemic immune inflammation index, ratio of lymphocytes to monocytes, lactate dehydrogenase and prognosis of diffuse large Bcell lymphoma patients

BACKGROUND In malignant tumors,inflammation plays a vital role in the development,invasion,and metastasis of cancer cells.Diffuse large B-cell lymphoma(DLBCL),the most common malignant proliferative disease of the lymphatic system,is commonly associated with inflammation.The international prognostic index(IPI),which includes age,lactate dehydrogenase(LDH),number of extranodal lesions,Ann Arbor score,and Eastern Cooperative Oncology Group(ECOG)score,can evaluate the prognosis of DLBCL.However,its use in accurately identifying highrisk patients and guiding treatment is poor.Therefore,it is important to find novel immune markers in predicting the prognosis of DLBCL patients.AIM To determine the association between the systemic immune inflammation index(SII),ratio of lymphocytes to monocytes(LMR),ratio of LMR to LDH(LMR/LDH),and prognosis of patients with DLBCL.METHODS A total of 68 patients diagnosed with DLBCL,treated in our hospital between January 2016 and January 2020,were included.χ2 test,Pearson’s R correlation,Kaplan Meier curves,and Cox proportional risk regression analysis were used.The differences in the SII,LMR,and LMR/LDH among patients with different clinicopathological features were analyzed.The differences in progression-free survival time among patients with different SII,LMR,and LMR/LDH expressions and influencing factors affecting the prognosis of DLBCL patients,were also analyzed.RESULTS The LMR and LMR/LDH in patients with Ann Arbor stage III–IV,ECOG score≥2,and SII,IPI score 2–5 were significantly higher than those of patients with Ann Arbor stage I-II and ECOG score<2(P<0.05).Patients with high SII,LMR,and LMR/LDH had progression-free survival times of 34 mo(95%CI:32.52–38.50),35 mo(95%CI:33.42–36.58)and 35 mo(95%CI:33.49–36.51),respectively,which were significantly lower than those with low SII,LMR,and LMR/LDH(P<0.05);the SII,LMR,and LMR/LDH were positively correlated(P<0.05).Cox proportional risk regression analysis showed that the SII,LMR,and LMR/LDH were influencing factors for the prognosis of DLBCL patients(hazard ratio=1.143,1.665,and 1.704,respectively;P<0.05).CONCLUSION The SII,LMR,and LMR/LDH are related to the clinicopathological features of DLCBL,and they also influence the prognosis of patients with the disease.

Prognostic value of systemic immune.inflammation index in patients with gastric cancer

Background:Inflammation-based indexes have been used to predict survival and recurrence in cancer patients.Systemic immune-inflammation index(Sll) was reported to be associated with prognosis in some malignant tumors.In the present study,we aimed to explore the association between Sll and the prognosis of patients with gastric cancer.Methods:We retrospectively analyzed data from 444 gastric cancer patients who underwent gastrectomy at the First Affiliated Hospital of Sun Yat-sen University between January 1994 and December 2005.Preoperative Sll was calculated.The Chi square test or Fisher's exact test was used to determine the relationship between preoperative Sll and clinicopathologic characteristics.Overall survival(OS) rates were estimated using the Kaplan-Meier method,and the effect of Sll on OS was analyzed using the Cox proportional hazards model.Receiver operating characteristic(ROC)curves were used to compare the predictive ability of Sll,NLR,and PLR.Results:Sll equal to or higher than 660 was significantly associated with old age,large tumor size,unfavorable Borrmann classification,advanced tumor invasion,lymph node metastasis,distant metastasis,advanced TNM stage,and high carcino-embryonic antigen level,high neutrophil-lymphocyte ratio,and high platelet-lymphocyte ratio(all P<0.05).High Sll was significantly associated with unfavorable prognosis(P<0.001) and Sll was an independent predictor for OS(P=0.015).Subgroups analysis further showed significant associations between high Sll and short OS in stage Ⅰ,Ⅱ,Ⅲ subgroups(all P<0.05).Sll was superior to NLR and PLR for predicting OS in patients with gastric cancer.Conclusion:Preoperative Sll level is an independent prognostic factor for OS in patients with gastric cancer.

Effects of the Chinese Medicinal Herb Com plex Additives on Non-specific Immunity of Amursturgeon( Acipenser schrencki Brandt)

This study was to investigate the effects of aqueous decotion from three Chinese medicinal herb additives （ Cyrtomium fortunei, prescription I and prescription II） on non-specific immunity of 1 ＋ age old Amur sturgeon （Acipenser schrencki Brandt） by oral perfusion. Cyrtomiumfortunei, prescription I and prescription II were orally given to 15 fishes for each experimental group once a day, with the concentration of 9,175 and 36 g/S0 kg body weight, respectively. The administration was lasted for 14 days. Meanwhile, distilled water was orally given as the control. After the experiment, some of the experimental fishes were stimulated with high temperature （30 ℃ ） for two hours. Sampling was performed from fishes treated at 22 ℃ and 30 ℃ for measuring the protein content in the serum, phagocytic activity of leucocytes and the activity of the lysozyme in six tissues. The results indicated that Cyrtomiumfortunei and prescription II could help to enhance the content of various proteins and the phagocytic activity of leucocytes. There was no significant change in the effects between these two additives at either the normal temperature or high temperature. Prescription I did not show an obvious effect on the immunity of fishes at the normal temperature, but it did in promo- ting high-efficiency response and improving immunoregulation of fish shocked by some stimuli.

Effect of Ammonia-Nitrogen Stress on Non-specific Immunity of Hybrid Tilapia(Oreochromis niloticus× Oreochromis areus)

The juveniles of hybrid tilapia （ Oreochromis niloticus x Oreochromis areus） were exposed to ananonia-nitrogen （N） （0, 2.5, 5, 10 and 20 mg/L） for 0, 12, 24, 48 and 72 h to evaluate the effect of ammonia-N stress on their non-specific immunity. Results show that the activity of serum lysozyme decreased signifi- candy with extension of stress time （P 〈 0.05）. The total antioxidant capacity （T-AOC） and activity of antioxidase in liver were significantly affected. The activi- ty of T-AOC and total superoxide dismutase （T-SOD） of fish exposed to ammonia-N were initially decreasing then increasing （ P 〈 0.05 ）. Activities of catalase （CAT） and glutathione peroxidase （GSH-Px） were correlated with concentrations of ammonia-N. Fish exposed to lower concentrations （2.5 mg/L or 5 mg/L） showed decreased CAT activity within 24 h （P 〈 0.05 ）, while those exposed to higher concentrations （10 mg/L or 20 mg/L） initially showed increased then decreased activity of CAT. Except for the highest concentration groups, fish exposed to ammonia-N showed inductive activity of GSH-Px （ P 〈 0.05 ）. Under the ex- perimental conditions, non-specific immunity of tilapia was affected by ammonia-N stress, and the impact was increased with increased concentration and extension of time.

Shock index of patients with sepsis after continuous blood purification treatment and its relationship with systemic inflammatory response syndrome and immune response

Objective:To study the shock index of patients with sepsis after continuous blood purification (CBP) treatment and its relationship with systemic inflammatory response syndrome and immune response.Methods:A total of 88 patients with sepsis who underwent continuous blood purification treatment in our hospital between June 2012 and May 2016 were chosen as research subjects, shock index (SI) was compared before and after the treatment, and according to the level of SI after treatment, all patients were divided into shock group (n=27) with SI>0.5 points and no shock group (n=61) with SI≤0.5 points. Serum contents of inflammatory mediators, Th1/Th2 cellular immunity indexes, immunoglobulin and complement were compared between two groups of patients after treatment.Results: The level of SI in patients with sepsis was significantly lower than that before treatment. Serum contents of inflammatory mediators PCT, CRP and HMGB1 in no shock group were lower than those in shock group, contents of Th1 cytokines IL-2 and IFN-γ were higher than those in shock group, contents of Th2 cytokines IL-10 and IL-13 were lower than those in shock group, and contents of IgG, IgM, IgA, C3 and C4 were higher than those in shock group.Conclusion: The level of SI decreases in the patients with sepsis after CBP treatment, and SI level is directly correlated with the systemic inflammatory response syndrome and immune response levels.
