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.展开更多

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.展开更多

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.展开更多

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.展开更多

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.展开更多

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

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 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.

文摘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.

文摘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.

文摘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.

文摘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.

文摘BACKGROUND We previously showed,using the Traditional Chinese Medicine System Pharmacology Database,that Gegen Qinlian decoction(GQD)had a direct antitumor effect,and was combined with programmed cell death protein(PD)-1 inhibitors to treat microsatellite stable(MSS)tumor-bearing mice.However,the effect of GQD on patients with colorectal cancer(CRC)is not clear.AIM To determine the therapeutic mechanism of GQD in improving immune function,reducing inflammation and protecting intestinal barrier function.METHODS Seventy patients with CRC were included in this study:37 in the control group and 33 in the treatment group.The proportions of CD4+T,CD8+T,natural killer(NK),NKT and T regulatory cells were measured by flow cytometry.Levels of the cytokines tumor necrosis factor(TNF)-α,interferon(IFN)-γ,interleukin(IL)-2,IL-6,IL-10 and serotonin(5-hydroxytryptamine;5-HT)in serum were assessed by enzyme-linked immunosorbent assay(ELISA).The expression of zonula occludens(ZO)-1,occludin,nuclear factor(NF)-κB and TNF-αin tumor and normal tissues was measured by immunohistochemistry.The composition of gut microbiota from patients in the treatment group was assessed using 16S rDNA analysis.RESULTS There were no adverse events in the treatment group.The proportion of CD4+T cells and NKT cells in the post-treatment group was significantly higher than that in the pre-treatment and control groups(P<0.05).The level of TNF-αin the posttreatment group was significantly lower than that in the pre-treatment and control groups(P<0.05).The concentration of 5-HT in the post-treatment group was significantly lower than that in the pre-treatment group(P<0.05).The expression of ZO-1 and occludin in tumor tissues in the treatment group was significantly higher than that in the control group(P<0.05).The expression of ZO-1 in normal tissues of the treatment group was significantly higher than that in the control group(P=0.010).Compared with the control group,expression of NF-κB and TNF-αin tumor tissues of the treatment group was significantly decreased(P<0.05).Compared with the pre-treatment group,GQD decreased the relative abundance of Megamonas and Veillonella.In addition,GQD increased the relative abundance of Bacteroides,Akkermansia and Prevotella.CONCLUSION GQD enhances immunity and protects intestinal barrier function in patients with CRC by regulating the composition of gut microbiota.

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.
