Meanwhile the winter immunoenhancement hypothesis, which holds that animals’ immune function would be enhanced in winter or winter-like conditions, was tested. Gradual shortening day length had no effect on body mass and body composition including wet carcass mass, the subcutaneous, retroperitoneal, mesenteric and total body fat masses in Siberian hamsters. The masses of liver and small intestine with contents were higher in the SD group than in the Con group, however other organ masses such as brain, heart, kidney and so on did not differ between the two groups. Phytohemagglutinin (PHA) response after 24 h of PHA injection was enhanced by the shortening photoperiod, which supported the winter immunoenhancement hypothesis. The masses of spleen and thymus, white blood cells, bacteria killing capacity indicative of innate immunity were not affected, which did not support this hypothesis. In summary, gradually decrease in day length increased cellular immunity, but had no effect on other immunological parameters in Siberian hamsters.展开更多

Methods： A total of 96 patients with esophageal cancer or cardiac cancer who underwent surgical treatment in our hospital from June 2007 to December 2010 were enrolled in this study. They were divided into EN group （n=50） and parenteral nutrition （PN） group （n=46） based on the nutrition support modes. The body weight, time to first flatus/defecation, average hospital stay, complications and mortality after the surgery as well as the liver function indicators were recorded and analyzed. Peripheral blood samples were collected on the days 1, 4 and 7 after surgery. The plasma diamine oxidase （DAO） activity and D-lactate level were determined to assess the intestinal permeability. The plasma endotoxin levels were determined using dynamic turbidimetric assay to assess the protective effect of EN on intestinal mucosal barrier. The postoperative blood levels of inflammatory cytokines and immunoglobulins were determined using enzyme- linked immunosorbent assay （ELISA）. Results： After the surgery, the time to first flatus/defecation, average hospital stay, and complications were significantly less in the EN group than those in the PN group （P〈0.05）, whereas the EN group had significantly higher albumin levels than the PN group （P〈0.05）. On the 7th postoperative day, the DAO activity, D-lactate level and endotoxin contents were significantly lower in the EN group than those in the PN group （all P〈0.05）. In addition, the EN group had significantly higher IgA, IgG, IgM, and CD4 levels than the PN group （P〈0.05） but significantly lower IL-2, IL-6, and TNF-a levels （P〈0.05）. Conclusions： In elderly patients with esophageal cancer or cardiac cancer, early EN after surgery can effectively improve the nutritional status, protect intestinal mucosal barrier （by reducing plasma endoxins）, and enhance the immune function展开更多

文摘Objective:To improve the efficacy of Astragalus membranaceus(Fisch.)Bunge(A.membranaceus,Huang Qi),and to further develop and utilize it,fermentation technology was applied to the stem and leaf of A.membranaceus to enhance its immune function.Methods:In this study,we fermented A.membranaceus stem and leaf(ASL)with probiotics and inves-tigated its immune function.Firstly,we screened suitable strains for ASL fermentation and optimized the fermentation process.Secondly,we determined the antioxidant capacity of fermented ASL and its effect on inflammation in mouse monocyte-macrophage cell.Finally,the immunocompromised mice were treated with fermented ASL to investigate the changes in their immune ability.Results:Among the 10 selected probiotics,Lactobacillus plantarum was the most suitable strain for ASL fermentation.After optimization of the fermentation process,the content of saponins in fermented ASL was significantly increased.The fermented ASL exhibited strong anti-inflammatory and antioxidant activities in vitro.The in vivo immune efficacy improved by promoting the development of the spleen and thymus,as well as raising the immunoglobulin M,tumor necrosis factor-α,and interleukin-1β levels of in the serum.Conclusion:This study contributes to developing the non-medicinal parts of A.membranaceus,expands its medicinal resources,highlights the potential of fermentation technology to enhance these parts,and provides a reference for further development.Based on this approach,we can promote using non-me-dicinal parts of herbal medicines,minimize drug waste,and offer a reference for developing non-me-dicinal components in Chinese herbal medicines.
文摘BACKGROUND Gastrointestinal(GI)surgery can significantly affect the nutritional status and immune function of patients.This study aimed to investigate the effects of personalized nutritional care on the recovery of immune function in patients who underwent postoperative GI surgery.AIM To study examines personalized nutritional care’s impact on immune function recovery,nutritional status,and clinical outcomes after GI surgery.METHODS This observational study included 80 patients who underwent GI surgery between 2021 and 2023.Patients received personalized nutritional care based on their individual needs and surgical outcomes.Immune function markers including lymphocyte subsets,immunoglobulins,and cytokines were measured preoperatively and at regular intervals postoperatively.Nutritional status,clinical outcomes,and quality of life were assessed.RESULTS Patients receiving personalized nutritional care showed significant improvements in immune function markers compared to baseline.At 4 weeks postoperatively,CD4+T-cell counts increased by 25%(P<0.001),while interleukin-6 levels decreased by 40%(P<0.001).Nutritional status,as measured by prealbumin and transferrin levels,improved by 30%(P<0.01).Postoperative complications reduced by 35%compared to historical controls.The quality-of-life scores improved by 40%at 3 months postoperatively.CONCLUSION Personalized nutritional care enhances immune function recovery,improves nutritional status,and reduces complications in patients undergoing postoperative GI surgery,highlighting its crucial role in optimizing patient outcomes following such procedures.
文摘BACKGROUND Although surgery remains the primary treatment for proximal gastric cancer(PGC),ongoing refinements in surgical strategies are essential to improving clinical outcomes.AIM To investigate the effect of double-tract reconstruction(DTR)on immune function and stress response in patients undergoing laparoscopic proximal gastrectomy(LPG).METHODS In total,78 patients with PGC admitted between August 2020 and August 2024 were enrolled.The research group consisted of 39 patients who underwent DTR+LPG,whereas the control group comprised 39 patients who underwent laparoscopic total gastrectomy with Roux-en-Y esophagojejunostomy.Perioperative indices(intraoperative blood loss,digestive tract anastomosis time,and time to first postoperative flatus),postoperative complications(intestinal obstruction,anastomotic ulcer,diarrhea,dumping syndrome,and gastroesophageal reflux),nutritional parameters(serum albumin,hemoglobin,and body mass index),immune function immunoglobulin(IgG,IgA,and IgM),and stress response indicators(C-reactive protein,interleukin-6,and tumor necrosis factor-α)were collected and analyzed for both groups.RESULTS The intraoperative blood loss was lower(P<0.05),and the time to first postoperative flatus time was shorter(P<0.001)in the research group than in the control group.The two groups had comparable digestive tract anastomosis time(P>0.05).The overall complication rate was significantly lower in the research group than in the control group(P=0.042).Compared with the control group,the research group exhibited notably higher albumin,hemoglobin,and body mass index levels at 2 and 3 months postoperatively,as well as considerably high immunoglobulin(Ig)G,IgA,and IgM levels on postoperative day 1(P<0.05).The postoperative levels of C-reactive protein,interleukin-6,and tumor necrosis factor-αwere also lower in the research group than in the control group(P<0.001).CONCLUSION The combination of DTR and LPG in the treatment of patients with PGC is more effective in enhancing immune function and suppressing stress responses,showing more advantages over laparoscopic total gastrectomy.
文摘Objective:To investigate the effects of nebulizedα-interferon on immune function in elderly patients with respiratory tract infection.Methods:A total of 120 elderly patients with respiratory tract infection admitted to our hospital from June 2023 to June 2024 were selected and randomly divided into an observation group(n=60)and a control group(n=60)using the envelope method.The control group received conventional treatment,while the observation group received additional nebulizedα-interferon therapy based on conventional treatment.After the same treatment period,changes in immune function indicators(immunoglobulins IgG,IgA,IgM)were compared between the two groups.Patients were also followed up for 3 months to observe the frequency of respiratory tract infection recurrences.Results:After treatment,IgA and IgM levels decreased significantly,while IgG levels increased significantly in both groups.The improvement in each indicator was more pronounced in the observation group than in the control group(P<0.05).By the end of the follow-up period,all 120 patients had successfully completed the follow-up,and no patients were lost to follow-up.The frequency of respiratory tract infection recurrences was lower in the observation group than in the control group(P<0.05).Conclusion:Nebulizedα-interferon can improve immune function and reduce the frequency of recurrences in elderly patients with respiratory tract infection.

文摘The mechanisms of mushroom polysaccharides on immune functions and lipid metabolism of aged mammals have not been fully elucidated.In the present study,after assessing the impacts of one type of Lentinula edodes-derived polysaccharides,named L2,on immune functions and blood lipid profiles,isobaric tags for relative and absolute quantification(iTRAQ)-based proteomic profiling of the small intestinal tissues from aged mice treated with L2 was performed.L2 reversed immune function declines and modulated the lipid metabolism of aged mice evidenced by increased levels of serum TC,HDL-C,and LDL-C,and reduced levels of serum TG.Moreover,a total of 95 differentially regulated proteins(DRPs) were identified,of which75 were up-regulated and 20 were down-regulated.Most of the DRPs were involved in intracellular and extracellular structure organization,and cellular and metabolic regulation.Particularly,approximately 16 and 9 DRPs participated in the regulation of immune functions and lipid metabolism,respectively.Furthermore,protein-protein interaction analysis highlighted that cadherin-1,plectin,cadherin-17,Ras GTPase-activating-like protein IQGAP2,and ezrin might be key proteins in response to L2 treatment.These findings provide new insights into the biological mechanisms of mushroom polysaccharides in anti-aging from a proteomic perspective.
文摘Objective:To analyze the efficacy of whole-course local simultaneous integrated boost intensity-modulated radiotherapy(SIB-IMRT)on patients with locally advanced esophageal squamous cell carcinoma(ESCC).Methods:88 patients with ESCC admitted to the hospital between October 2022 and October 2024 were selected and randomly divided into two groups using a random number table.The experimental group received SIB-IMRT treatment,while the control group received conventional intensity-modulated radiotherapy(C-IMRT).The objective remission rate,immune function,tumor markers,and adverse reaction rate were compared between the two groups.Results:The objective remission rate in the experimental group was higher than that in the control group(P<0.05).Before treatment,there was no difference in immune function levels and tumor marker levels between the two groups(P>0.05).After treatment,the immune function levels in the experimental group were better than those in the control group,and the tumor marker levels were lower than those in the control group(P<0.05).The adverse reaction rate in the experimental group was lower than that in the control group(P<0.05).Conclusion:SIB-IMRT can improve the objective remission rate of patients with ESCC,protect their immune function,down-regulate tumor marker levels,and prevent side effects after treatment.

文摘Objective:To clarify the specific mechanisms of action of raw Phellodendron chinense Schneid.(RPC)and saltwater-processed PC(SPC)in the treatment of rats with a kidney-yin deficiency pattern(KYDP).Methods:Healthy rats were administered hydrocortisone to establish a KYDP model.The rats were divided into seven groups:blank control,model,positive control(Liuwei Dihuang pills),high-dose RPC,low-dose RPC,high-dose SPC,and low-dose SPC.Enzyme-linked immunosorbent assay was used to measure the levels of cAMP,cGMP,TRH,TSH,T3,T4,IFN-g,TNF-a,and testosterone in the serum and the levels of Na^(+)-K^(+)-ATPase and Ca ^(2+)-Mg ^(2+)-ATPase in the liver.TRH mRNA expression in the rat hypo-thalamus was measured using RT-PCR.THRa1+2 protein expression in the hypothalamus of rats was measured using Western blot.Immunohistochemistry was performed to determine the expression levels of FAS,FasL,and TSHR.Flow cytometry was used to determine CD4^(+)and CD8^(+)T lymphocyte levels.Illumina MiSeq sequencing technology was used to evaluate the diversity of intestinal flora in KYDP rats.Results:The cAMP/cGMP ratio was significantly higher in the model group than in the blank control group(P=0.048).Compared with the model group,after administration,the levels of the above-mentioned serum and liver indexes decreased,except that of testosterone.The CD4^(+)/CD8^(+)ratio also decreased.Compared with the RPC group,the levels of T3,IFN-g,FAS,FasL,and TSHR in the SPC group decreased whereas that of testosterone increased.Additionally,immune function and intestinal flora diversity improved in the SPC group.SPC proved to be more effective in improving liver energy meta-bolism in KYDP rats than RPC.Conclusion:SPC had a better therapeutic effect on KYDP than RPC.The underlying mechanism of action may be related to improvements in liver energy metabolism,immune function,and intestinal flora diversity.
文摘BACKGROUND Human herpesvirus type 7(HHV-7)is a less common herpes virus that usually causes mild,self-limiting illnesses.However,in recent years,there have been increasing reports of HHV-7 causing serious central nervous system infections,especially meningitis.The pathogenesis and clinical features of HHV-7 meningitis,particularly in adolescents with normal immune function,remain incompletely studied.Therefore,the purpose of this report is to share a case of HHV-7 meningitis in an immunocompetent adolescent with a view to deepening our understanding of the disease.CASE SUMMARY A 12-year-old female was admitted with fever,headache,and vomiting.4 d before admission,the patient developed a fever without obvious induction,with a temperature up to 39.5℃,no convulsions,accompanied by chills,headaches,fatigue,and no muscle aches.The patient was treated with fever reduction,which could be reduced to 38℃;repeated high fever,accompanied by vomiting 7-8 times;and no abdominal pain or diarrhea.The patient was diagnosed with"acute suppurative tonsillitis"in a local hospital,and the blood routine was generally normal.The patient was given symptomatic support treatment such as"ceftriaxone sodium"and antiemetic rehydration for 2 d,and his condition did not improve.The patient's physical examination showed pharyngeal congestion,bilateral tonsil grade I hypertrophy,regression of purulent secretions,and cervical resistance.Ocular B-ultrasound:Opacity of the vitreous body and edema of the optic disc in both eyes.Optical coherence tomography examination showed that the macular fovea was generally normal in both eyes,with edema of the optic disc.DNA virus monitoring results:HHV-7.We gave ganciclovir antiviral therapy,dexamethasone anti-inflammatory treatment,mannitol to reduce cranial pressure,omeprazole to protect gastrointestinal mucosa,and calcium and potassium supplementation.CONCLUSION This study reports a case of HHV-7 meningitis in an adolescent with normal immune function.Through comprehensive analysis of the clinical manifestations,laboratory tests,and treatment methods of the patient,it is found that early identification and antiviral treatment are essential for the outcome of the disease.This case suggests that despite normal immune function,adolescents may still suffer from herpes virus type 7 meningitis,so clinicians should be vigilant and take effective treatment measures in time.
文摘BACKGROUND Infant hepatitis syndrome(IHS)is a clinical syndrome in infants less than one year of age with generalized skin jaundice,abnormal liver function,and hepato-megaly due to various etiologies such as infection.AIM To investigate the effect of IHS patients,after treatment with arsphenamine-based peptides,on patients'liver function damage and immune function.METHODS Of 110 patients with IHS treated in our hospital from January 2019 to January 2021 were grouped according to the randomized residual grouping method,with 5 cases in each group shed due to transfer,etc.Ultimately,50 cases remained in each group.The control group was treated with reduced glutathione,and the treat-ment group was treated with sesquiterpene peptide based on the control group.Observe and compare the differences in indicators after treatment.RESULTS The comparison of serum total bilirubin,direct bilirubin,and serum alanine transferase after treatment was significantly different and lower in the treatment group than in the control group(P<0.05).The comparison of CD4+,CD3+,CD4+/CD8+after treatment was significantly different and higher in the treatment group than in the control group,and the comparison was statist-ically significant(P<0.05).The complication of the two groups showed that the rash,cough and sputum,elevated platelets,and gastrointestinal reactions in the treatment group were significantly lower than those in the control group,and the differences were statistically significant by test(P<0.05).CONCLUSION The comparative study of IHS treated with arsphenamine combined with reduced glutathione is more effective.

文摘In order to understand the effect of gradual changes in photoperiod on immune function, adult female Siberian hamsters (Phodopus sungorus) were randomly divided into the control group (12L:12D, Con, n = 11) and the shortening day length group (SD, n = 11), in which day length was reduced from 12:12 h to 8:16 h light-dark cycle at the pace of half an hour every week. Meanwhile the winter immunoenhancement hypothesis, which holds that animals’ immune function would be enhanced in winter or winter-like conditions, was tested. Gradual shortening day length had no effect on body mass and body composition including wet carcass mass, the subcutaneous, retroperitoneal, mesenteric and total body fat masses in Siberian hamsters. The masses of liver and small intestine with contents were higher in the SD group than in the Con group, however other organ masses such as brain, heart, kidney and so on did not differ between the two groups. Phytohemagglutinin (PHA) response after 24 h of PHA injection was enhanced by the shortening photoperiod, which supported the winter immunoenhancement hypothesis. The masses of spleen and thymus, white blood cells, bacteria killing capacity indicative of innate immunity were not affected, which did not support this hypothesis. In summary, gradually decrease in day length increased cellular immunity, but had no effect on other immunological parameters in Siberian hamsters.
文摘Objective:To explore the effect of immunotherapy on the gut microbiota,intestinal barrier,and immune function in patients with gastric cancer.Methods:From July 2023 to July 2024,60 patients with gastric cancer from our hospital were randomly divided into two groups,the control group and the study group,with 30 patients in each group.The control group received conventional treatment,while the study group received immunotherapy.A comparative analysis was conducted between the two groups on gut microbiota content(Bifidobacterium,Fusobacterium nucleatum,Streptococcus,Lactobacillus acidophilus),intestinal barrier indicators[D-lactate(D-LA),diamine oxidase(DAO),lipopolysaccharide(LPS)],immune function indicators[Immunoglobulin A(IgA),Immunoglobulin G(IgG),Immunoglobulin M(IgM)],adverse reactions,and treatment effects.Results:After treatment,the content of Bifidobacterium and Fusobacterium nucleatum in the study group was higher than in the control group,while the content of Streptococcus and Lactobacillus acidophilus was lower than in the control group(P<0.05).The levels of D-lactate and DAO in the study group were lower than in the control group,while the LPS level in the study group was higher(P<0.05).The levels of IgA and IgG in the study group were lower than in the control group,and the IgM level was also lower than in the control group(P<0.05).After treatment,the total incidence of adverse reactions in the study group was lower than in the control group(P<0.05).The overall treatment efficacy rate in the study group was higher than in the control group(P<0.05).Conclusion:Immunotherapy in patients with gastric cancer can improve gut microbiota,intestinal barrier,and immune function,reduce the occurrence of adverse reactions,and promote better clinical treatment outcomes,making it worthy of clinical recommendation.
文摘Objective:To explore the therapeutic effect of laparoscopic radical colorectal cancer treatment in colorectal cancer patients.Methods:A total of 50 colorectal cancer patients treated between August 2018 and August 2023 were randomly divided into two groups:Group A underwent laparoscopic radical colorectal cancer surgery,while Group B received open surgery.Clinical indicators,inflammatory factors,immune function indicators,and complications were compared between the two groups.Results:Group A showed significantly shorter operation times,faster recovery times,and reduced hospital stays compared to Group B.Additionally,Group A had less abdominal drainage and intraoperative bleeding(P<0.05).Levels of interleukin(IL)-4,IL-6,ultrasensitive C-reactive protein(hs-CRP),and tumor necrosis factor-alpha(TNF-α)were lower in Group A compared to Group B(P<0.05).Furthermore,immune function indicators,including CD3+,CD4+,CD8+,and CD4+/CD8+ratios,were better in Group A(P<0.05).The complication rate in Group A was also lower than in Group B(P<0.05).Conclusion:Laparoscopic radical treatment for colorectal cancer is efficient and feasible,causing minimal immune function impairment and inflammatory response.It also shortens postoperative recovery time.
文摘Objective: To study the effects of andrographolide on immune functions and the immune mechanism in clinical therapy.Methods: The amounts of IFN-α,IFN-γ, TNF-α, IL-8 in the peripheral blood mononuclear cells (PBMC) culture supernatants dealt with by different concentrations of LianBiZhi (LBZ) injection, the effective component of which is andrographolide, were detected by biological activity test or ELISA in vitro. The effects of LBZ injection on macrophage phagocytotic function and natural killer cells cytotoxicity were examined by means of macrophage to phagocytize cock erythrocyte and measurement of lactate dehydrogenase (LDH) activity released from the damaged cells, respectively.Results: The LBZ injection could not only enhance the phagocytosis activity of peritoneal macrophage from guinea pig to phagocytosis cock erythrocytes, but also augment the cytotoxicity mediated by natural killer cells from PBMCs.Conclusion: Andrographolide is an immunostimulant agent which can modulate both antigen specific and nonspecific immune function by means of its natural killer cells, macrophage and cytokines.
文摘Radioimmunoassay,enzyme linked immunospot assay and enzyme immunoassay were used for the determinations of plasma steroid hormone's level,antibody producing cell's counting and IgM level in this study.The decreased number of antibody producing cells and low IgM levels were observed in sexual immature rainbow trout during the spawning season.These fish were reared under almost constant water temperature and natural photoperiod.Moreover,low IgM level was also observed in immature rainbow trout,which were reared under short photoperiod,and IgM level was not changed by treatment of testosterone.The results suggest that photoperoid may cause the changes in immune competence.It is possible that circadian rhythm accompanied with photoperiod may influence physiological function of fish,so that immune competence is changed.

文摘[Objective] This study aimed to investigate effects of Echinacea compound on the immune function of weaned piglets. [Method] Eighty Duroc x Landrace x Yorkshire crossbred piglets were randomly divided into four groups： control group （drug-free group）, 1.5% close group, 1.0% dose group and 0.5% dose group. Blood samples of piglets were collected at 20, 35, 50, 60, 70 and 80 days old, respective- ly, to determine neutrophil leukocyte percentage in peripheral blood, lymphocyte trapsformation rate and the levels of antibodies against classical swine fever, porcine reproductive and respiratory syndrome disorder. [Result] Applying a certain dose of Echinacea compound could significantly increase neutrophil leukocyte per- centage in peripheral blood and lymphocyte transformation rate （P〈0.05）, and ex- tremely significantly improve the levels of antibodies against classical swine fever, porcine reproductive and respiratory syndrome disorder （P〈0.01）. [Conclusion] Echi- nacea compound has played a certain role in promoting nonspecific and specific im- mune function of piglets.
文摘To explore the effect of early enteral nutrition （EN） on postoperative nutritional status, intestinal permeability, and immune 6anction in elderly patients with esophageal cancer or cardiac cancer. Methods： A total of 96 patients with esophageal cancer or cardiac cancer who underwent surgical treatment in our hospital from June 2007 to December 2010 were enrolled in this study. They were divided into EN group （n=50） and parenteral nutrition （PN） group （n=46） based on the nutrition support modes. The body weight, time to first flatus/defecation, average hospital stay, complications and mortality after the surgery as well as the liver function indicators were recorded and analyzed. Peripheral blood samples were collected on the days 1, 4 and 7 after surgery. The plasma diamine oxidase （DAO） activity and D-lactate level were determined to assess the intestinal permeability. The plasma endotoxin levels were determined using dynamic turbidimetric assay to assess the protective effect of EN on intestinal mucosal barrier. The postoperative blood levels of inflammatory cytokines and immunoglobulins were determined using enzyme- linked immunosorbent assay （ELISA）. Results： After the surgery, the time to first flatus/defecation, average hospital stay, and complications were significantly less in the EN group than those in the PN group （P〈0.05）, whereas the EN group had significantly higher albumin levels than the PN group （P〈0.05）. On the 7th postoperative day, the DAO activity, D-lactate level and endotoxin contents were significantly lower in the EN group than those in the PN group （all P〈0.05）. In addition, the EN group had significantly higher IgA, IgG, IgM, and CD4 levels than the PN group （P〈0.05） but significantly lower IL-2, IL-6, and TNF-a levels （P〈0.05）. Conclusions： In elderly patients with esophageal cancer or cardiac cancer, early EN after surgery can effectively improve the nutritional status, protect intestinal mucosal barrier （by reducing plasma endoxins）, and enhance the immune function
