[ Method] The constructed recombinant expression vector pET-ORF7 was transformed into Escherichia co1BL21 (DE3) and induced by IPTG under the optimal condition. After analysis of SDS-PAGE and Western Blot, the expression products were purified by Ni-NTA His · Bind Resin chrom- atographic column under denaturing condition and renatured by gradient dialysis. Subsequently, the immunological activity of the renatured recombinant protein was detected by Westem Blot and indirect ELISA. [ Result] The recombinant plasmid pET-ORF7 expressed in E. coli successfully, and the fusion protein was in the form of inclusion body. By SDS-PAGE detection, the molecular weight of the expression protein was approximate 33 kD, according with the expectation. Analysis by Bandscan software showed that the expressed fusion protein was about 50% of total bacterial protein of BL21 (DE3). Wastem Blot and indirect ELISA detection showed that the renatured protein could react with PRRSV positive serum specifically, indicating its good immunological activity. [ Conclusion] This study lays a foundation for the preparation of PRRSV monoclonal antibody and diagnostic kit.展开更多

[Method] All the 12 weaning pigs (Lulai pig, Laiwu pig and Yorkshire pig) weighing (12.6 ±0.5) kg were used in a 2 x3 factorial design. The main factors consisted of immunological challenge ( LPS or saline) and breeds ( Lulai pig, Laiwu pig and Yorkshire pig). On Day 1, six piglets of each breed were injected with LPS at the usage of 200 μg/kg BW or an equivalent amount of sterile saline, and in jected classical swine fever vaccine at the same time. Blood sample were collected on Day 2, 7 and 14 post injection to analyze the blood lympho cyte proliferation. The levels of antibodies against classical swine fever were tested on Day 1 prior to injection and on Day 7 and 14 post injection. [ Result] On Day 2 after injection, the lymphocyte transformation rate of piglets injected with LPS were significantly (P〈O. 01 ) increased compared with piglets injected with saline. The lymphocyte transformation rate of Laiwu piglets was significant higher than that of Yorkshire piglets ( P 〈 0.05). Effects of immunological stress on the level of antibodies against classical swine fever were not significantly different among different breeds of pig lets. [ Conclusion] LPS can effectively stimulate cellular immunity response in different breeds of piglets, and the immune response ability is different among various breeds of piglets.展开更多

[Method] The vaccine (0.2 ml) containing aluminum phosphate adjuvant (90 μg), pcDNA/F (200μg), and pcDNA/chlL-18 (200 μg) was prepared. The 7 d old chick- ens to be tested were randomly divided into six groups (12 chickens in each group) and immunized through intramuscular injection with inactivated Newcastle disease vaccines, pcDNA/F+pcDNA/chlL-18+phosphate aluminum, pcDNA/F, pcDNA/F.+pcDNA/ chlL-18, pcDNA/F+aluminum phosphate, and physiological saline respectively; the secondary immunization was conducted with the same dose when the chickens were 21 d old. Their blood was sampled 0, 7, 14, 21, 28 d after first immunization. Anti- body titer was detected with ELISA and T cell transformation rate was measured with MIT. Experimental chicken will be challenged with 30 LD50 NDV virulence 28 d after first immunization. [Result] The survival rate of the chickens immunized with pcDNA/F+aluminium phosphate+pcDNA/chlL-18 achieved 8/12, higher than that of those immunized with pcDNA/F 4/12 and pcDNA/F+pcDNA/chlL-18 (6/12). The NDV antibody titer of the chickens immunized with pcDNA/F+ aluminum phosphate, pcD- NA/F+pcDNA/chlL-18 and pcDNA/F+pcDNA/chlL-18+aluminum phosphate is not differ- ent (P〉0.05), but significantly lower than that of the chickens immunized with tradi- tional vaccine (P〈0.05). The T cell transformation rate of the chickens immunized with pcDNA/F+pcDNA/chlL-18+aluminium phosphate was obviously higher than that of the chickens immunized with pcDNA/F (P〈0.05). The T cell transformation rates of chickens immunized with pcDNA/F and the traditional vaccine showed no signifi- cant difference (P〉0.05). [Conclusion] Combination of aluminium phosphate and pcD- NA/chlL-18 can significantly enhance the immune effect of NDV F gene vaccine.展开更多

METHODS: Immunological liver injury in murine model was induced by Bacille Calmette-Guerin and lipopolysaccharide. Expression pattern and distribution of CXCL16 were examined by real-time quantitative RT-PCR and immunohistochemical analysis. Anti-CXCL16 antibody was administrated in vivo to investigate its effect on T-cell recruitment and acute hepatic necrosis. The survival of murine model was also evaluated. RESULTS, The murine immunological liver injury model was successfully established, CXCL16 expression increased and predominantly distributed in periportal areas and vascular endothelia in injured liver tissues. Administration of anti-CXCL16 Ab protected the mice from death and acute liver damage. Approximately 70% of the mice survived for 72 h in the anti-CXCL16 Ab treatment group, whereas 80% died within 72 h in control Ab group. The number of liver-infiltrating T lymphocytes was significantly reduced from 1.01×10^7 to 3.52×10^6/liver, compared with control Ab treatment. CONCLUSION: CXCL16 is involved in immunological liver injury by regulating T lymphocyte infiltration in liver tissue.展开更多

HCV lymphotropism represents an essential lap in the pathogenesis of virus-related autoimmune and lymphoproliferative disorders, ranging from clonal expansion of B-cells with organ-and non-organ-specific autoantibody production up to overt non-Hodgkin's lymphoma along a continuous step-by-step model of B-cell lymphomagenesis, where the intermediated mixed cryoglobulinemia could be considered as a stage of suppressible antigen-driven lymphoproliferation. HCV infection of lymphoid ceils could set up privileged reservoirs able to interfere with the host viral clearance efficiency and may be implicated in viral recurrence after apparently successful antiviral therapy. The HCV long-lasting extrahepatic replicative state generates an abnormal systemic immunological response, easily detectable by searching simple laboratory and clinical parameters, mainly represented by vasculitis-like skin features and hypocomplementemia.The presence or absence of this hypersensitivity pattern seems to correlate with the antiviral response and could be identified as a novel immunological cofactor. Further research is required to fully verify the real impact on therapeutic choice/regimen.展开更多

Methods:Fresh V.amygdalina leaves were collected within Nsukka area in Enugu State.The leaves were rinsed with distilled water.Two handful of cleaned fresh leaves were soaked in 200 mL water and squeezed gently by hand to a mixture.Clients were divided into four groups and each group was given different combination.They took the medication for four weeks.The immune effect was tested against marketed immune booster in some retroviral clients.Results:The mean absolute CD4 count was increased in the client who took the extract or supplement.And the clients who took both the extract and supplement had a greater increase in the CD4 count.The increased CD4 was significant as compared with the control group(P<0.05).The skin rashes were also improved in the entire groups.Conclusions:It can be concluded that the aqueous extract of V.amygdalina and immunace or both have immunological effect on HIV infected patients. Therefore,we suggest that the V.amygdalina extract or immunace or both could be used as adjuvant in the management of HIV/AIDS clients.展开更多

Significant advances...Many factors, such as environmental, microbial and endogenous stress, antigen localization, can trigger the immunological events that affect the ending of the diverse spectrum of ocular disorders. Significant advances in understanding of immunological and molecular mechanisms have been researched to improve the diagnosis and therapy for patients with ocular inflammatory diseases. Some kinds of ocular diseases are inadequately responsive to current medications;therefore, immunotherapy may be a potential choice as an alternative or adjunctive treatment, even in the prophylactic setting. This article first provides an overview of the immunological and molecular mechanisms concerning several typical and common ocular diseases; second, the functions of immunological roles in some of systemic autoimmunity will be discussed; third, we will provide a summary of the mechanisms that dictate immune cell trafficking to ocular local microenvironment in response to inflammation.展开更多

Materials & Methods Forty-two female Kunming mice were evenly divided into 7 groups by weight. Group A was control group; Group B was model of infertility. Group C, D and E were fed with normal, half and double dosage of Mianbu I respectively. Group F and G were fed with Mianbu II and prednisone Acetates respectively. Animal model of immunological infertility were set up by injecting mice sperm to the other 36 Kunming female mice except Group A. The AsAb levels in serum, cervical mucus were measured, the histological and immunohistochemistry changes in ovary and endometrium were observed, and the pregnancy indexes were compared in different groups. Results Compared with the infertility model group, the AsAb level in serum and cervical mucus in treatment group was lower. Less immune compounds in ovary and endometrium and atretic follicle of ovary was found in treatment group than in model and control group. The immune compounds in ovary and endometrium were less in the treatment group than that in the model and control group. Conclusion By regulating immunological system, Traditional Chinese Medicine compound mixfang Mianbu Fang lowers AsAb in the circulation system and special organs, eliminates immunological compound, repairs tissue impairment and increases pregnancy of female mice.展开更多

Clinical data of 80 CHB and 28 HBV-related LC patients who were administered with Ld T for 108 weeks and followed up were retrospectively analyzed. The liver function indicators including ALT, AST and γ-GT, HBV DNA copy number in serum and the rates of hepatitis B e antigen(HBe Ag) seroconversion were analyzed before and 12, 24, 36, 48, 60, 72, 84, 96 and 108 weeks after Ld T treatment in CHB and LC groups. Four serum fibrosis-related markers, including hyaluronic acid(HA), human laminin(LN), human type Ⅳ collagen(Ⅳ-C) and human N-terminal procollagen Ⅲ peptide(PC-Ⅲ), were detected before and after Ld T treatment in LC group. The results showed favorable viral suppression and biochemical responses after treatment with Ld T for 12 weeks, and a high rate of virological and biochemical control was maintained during the course of 108-week treatment in both CHB and LC groups. The four fibrosis-related markers, especially HA and LN, were down-regulated to some degrees in LC group. Moreover, Ld T treatment led to the fluctuation of the circulating interferon-γ(IFN-γ) and interleukin-10(IL-10) levels at different time points in CHB group. It was concluded that Ld T could favorably lead to the virological suppression and biochemical remission. Besides, IFN-γ and IL-10 may represent a suitable and effective predictor of responsiveness during Ld T therapy.展开更多

Materials & Methods Models of mice with immunological infertility were used by injection of mice sperm. These mice were treated with Mianbu Ⅰ, Mianbu Ⅱ or Prednisone Acetates. The characteristics on histology and immunohistochemistry of mice were analyzed. Results High level of AsAb was detected in serum and seminal vesicle plasma of model mice after treatment. Immune compounds mostly deposited in limiting membrane of seminiferous tubules, spermatogonium and epithelia of epididymis ducts. The number of spermatogenic cells per convoluted seminiferous tubule decreased. However, the Chinese medicine could significantly reduce the level of AsAb, or even eliminate the antibodies and clear out the immune compounds and increase the number of spermatogenic cells of seminiferous tubules. Conclusion Chinese Medicine Mianbu Ⅰand Ⅱ can regulate, absorb and clear out circulation and partial AsAb, as well as immunological compound. Hence, they can increase the number of spermatogenic cells of seminiferous tubules and increase the pregnancy of mice.展开更多

Methods: A total of 130 children with mycoplasma pneumonia were included in the study and randomized into the treatment group (n=65) and the control group (n=65). The patients in the control group were given azithromycin. On the above basis, the patients in the treatment group were given Yanhuning. The patients in the two groups were continuously treated for 7 d. The levels of serum inflammatory cytokines and immunological function indicators before and after treatment in the two groups were detected and compared. Results: When compared with before treatment, the serum IL-2 level after treatment in the two groups was significantly elevated, while IL-4, IL-10, IL-13, IL-6, TNF-α, and IFN-γ levels were significantly reduced;moreover, the improvement in the treatment group was significantly superior to that in the control group. When compared with before treatment, CD3+, CD4+, and CD4+/CD8+ after treatment in the two groups were significantly elevated, and those in the treatment group were significantly higher than those in the control group, while CD8+ was significantly reduced, but the comparison between the two groups was not statistically significant. When compared with before treatment, RBC-C3bR after treatment in the two groups was significantly elevated, while RBC-ICR was significantly reduced;moreover, the improvement in the treatment group was significantly superior to that in the control group. Conclusions: Yanhuning in combined with azithromycin in the treatment of mycoplasma pneumonia in children can significantly enhance the immunological function, and reduce the inflammatory reaction, with an effect significantly superior to that by single application of azithromycin.展开更多

文摘Histamine in food has attracted widespread attention due to the potential toxicity and associated health risk.However,its influences on immunological components,especially the function of key immune cells,are still poorly known.In this work,we explored the effects of exogenous histamine on the function of key immune cells such as intestinal epithelial cells,dendritic cells,and T cells.The results showed that histamine could affect the expression of allergy-related genes in CMT93 cells at a high dose of histamine.Moreover,it’s found that histamine could cause an imbalance in the levels of relevant immune factors secreted by dendritic cells and T cells,especially those related to allergy.At the same time,the proportion of MHC class IIpositive dendritic cells and the proportion of T helper 2(Th2)cells in CD4^(+)T cells increased after histamine stimulation.We concluded that the presence of a certain level of histamine in food may affect the expression of allergy-related cytokines,disrupt the balance of the immune homeostasis,and potentially lead to adverse immune reactions.This work demonstrated the importance of including the estimation of histamine’s immune safety in aquatic products rather than merely considering the potential risk of food poisoning.

文摘Oyster,as a common aquatic food,play an important role in shellfish allergy.In this study,2 tropomyosin(TM)isoforms TM-αand TM-β(TM-α/-β)in Alectryonella plicatula were identified.The sequences of 852 bp encoding 284 amino acids of TM-α/-βand 2 recombinant proteins were obtained,respectively.There were 12 amino acid differences between TM-α/-β.The results of immunological experiments indicated that TM-βhad stronger immunobinding activity and immunoreactivity than those of TM-α.Structural analysis showed that TM-βhad moreα-helix and higher surface hydrophobicity than TM-α.Sequences and epitopes alignment with shellfish TMs revealed that amino acids of TM-βwere more frequently recognized as IgE epitopes in other shellfish TMs than TM-α.Differences in structure and sequence account for the higher immunological activity of TM-βcompared to TM-α.These findings provide a theoretical basis for enriching the understanding of shellfish TM and accurate diagnosis of allergic components.
文摘Obstructive sleep apnea-hypopnea syndrome(OSAHS)is a complex disorder cha-racterized by symptoms resulting from intermittent hypoxia and hypopnea,with research indicating a crucial role of immune system dysregulation and genetic variations in its pathogenesis.A recent Zhao et al study utilizes Mendelian ran-domization analysis to explore the causal relationship between immune cell characteristics and OSAHS.The study identifies specific lymphocyte subsets as-sociated with OSAHS,providing valuable insights into the disease's pathophy-siology and potential targets for therapeutic intervention.The findings underscore the significance of genetic and immunological factors in sleep disorders,offering a fresh perspective on OSAHS's complexities.Compared to existing literature,Zhao et al's study stands out for its focus on genetic markers and specific immune responses associated with OSAHS,expanding upon previous research primarily centered on systemic inflammation.In conclusion,the study represents a signi-ficant advancement in the field,shedding light on the causal role of immune cells in OSAHS and paving the way for future research and targeted treatments.

文摘[Objective] The aim of this study was to realize efficient expression of the porcine reproductive and respiratory syndrome virus (PRRSV) ORF7 gene in genetic engineering bacteria and analYze the immunological activity of the recombinant protein after purification. [ Method] The constructed recombinant expression vector pET-ORF7 was transformed into Escherichia co1BL21 (DE3) and induced by IPTG under the optimal condition. After analysis of SDS-PAGE and Western Blot, the expression products were purified by Ni-NTA His · Bind Resin chrom- atographic column under denaturing condition and renatured by gradient dialysis. Subsequently, the immunological activity of the renatured recombinant protein was detected by Westem Blot and indirect ELISA. [ Result] The recombinant plasmid pET-ORF7 expressed in E. coli successfully, and the fusion protein was in the form of inclusion body. By SDS-PAGE detection, the molecular weight of the expression protein was approximate 33 kD, according with the expectation. Analysis by Bandscan software showed that the expressed fusion protein was about 50% of total bacterial protein of BL21 (DE3). Wastem Blot and indirect ELISA detection showed that the renatured protein could react with PRRSV positive serum specifically, indicating its good immunological activity. [ Conclusion] This study lays a foundation for the preparation of PRRSV monoclonal antibody and diagnostic kit.
文摘[ Objective] The research aimed to explore effects of an immunological stress on immune response in different breeds of piglets ( Lulai pig, Laiwu pig and Yorkshire pig). [Method] All the 12 weaning pigs (Lulai pig, Laiwu pig and Yorkshire pig) weighing (12.6 ±0.5) kg were used in a 2 x3 factorial design. The main factors consisted of immunological challenge ( LPS or saline) and breeds ( Lulai pig, Laiwu pig and Yorkshire pig). On Day 1, six piglets of each breed were injected with LPS at the usage of 200 μg/kg BW or an equivalent amount of sterile saline, and in jected classical swine fever vaccine at the same time. Blood sample were collected on Day 2, 7 and 14 post injection to analyze the blood lympho cyte proliferation. The levels of antibodies against classical swine fever were tested on Day 1 prior to injection and on Day 7 and 14 post injection. [ Result] On Day 2 after injection, the lymphocyte transformation rate of piglets injected with LPS were significantly (P〈O. 01 ) increased compared with piglets injected with saline. The lymphocyte transformation rate of Laiwu piglets was significant higher than that of Yorkshire piglets ( P 〈 0.05). Effects of immunological stress on the level of antibodies against classical swine fever were not significantly different among different breeds of pig lets. [ Conclusion] LPS can effectively stimulate cellular immunity response in different breeds of piglets, and the immune response ability is different among various breeds of piglets.
文摘[Objective] This study aimed to investigate the immunological adjuvant function of aluminium phosphate and chicken IL-18 in NDV F gene vaccine. [Method] The vaccine (0.2 ml) containing aluminum phosphate adjuvant (90 μg), pcDNA/F (200μg), and pcDNA/chlL-18 (200 μg) was prepared. The 7 d old chick- ens to be tested were randomly divided into six groups (12 chickens in each group) and immunized through intramuscular injection with inactivated Newcastle disease vaccines, pcDNA/F+pcDNA/chlL-18+phosphate aluminum, pcDNA/F, pcDNA/F.+pcDNA/ chlL-18, pcDNA/F+aluminum phosphate, and physiological saline respectively; the secondary immunization was conducted with the same dose when the chickens were 21 d old. Their blood was sampled 0, 7, 14, 21, 28 d after first immunization. Anti- body titer was detected with ELISA and T cell transformation rate was measured with MIT. Experimental chicken will be challenged with 30 LD50 NDV virulence 28 d after first immunization. [Result] The survival rate of the chickens immunized with pcDNA/F+aluminium phosphate+pcDNA/chlL-18 achieved 8/12, higher than that of those immunized with pcDNA/F 4/12 and pcDNA/F+pcDNA/chlL-18 (6/12). The NDV antibody titer of the chickens immunized with pcDNA/F+ aluminum phosphate, pcD- NA/F+pcDNA/chlL-18 and pcDNA/F+pcDNA/chlL-18+aluminum phosphate is not differ- ent (P〉0.05), but significantly lower than that of the chickens immunized with tradi- tional vaccine (P〈0.05). The T cell transformation rate of the chickens immunized with pcDNA/F+pcDNA/chlL-18+aluminium phosphate was obviously higher than that of the chickens immunized with pcDNA/F (P〈0.05). The T cell transformation rates of chickens immunized with pcDNA/F and the traditional vaccine showed no signifi- cant difference (P〉0.05). [Conclusion] Combination of aluminium phosphate and pcD- NA/chlL-18 can significantly enhance the immune effect of NDV F gene vaccine.

文摘AIM: To investigate the role of CXCL16 in the pathogenesis of immunological liver injury and to explore the possible mechanism ofT lymphocyte infiltration regulated by CXCL16. METHODS: Immunological liver injury in murine model was induced by Bacille Calmette-Guerin and lipopolysaccharide. Expression pattern and distribution of CXCL16 were examined by real-time quantitative RT-PCR and immunohistochemical analysis. Anti-CXCL16 antibody was administrated in vivo to investigate its effect on T-cell recruitment and acute hepatic necrosis. The survival of murine model was also evaluated. RESULTS, The murine immunological liver injury model was successfully established, CXCL16 expression increased and predominantly distributed in periportal areas and vascular endothelia in injured liver tissues. Administration of anti-CXCL16 Ab protected the mice from death and acute liver damage. Approximately 70% of the mice survived for 72 h in the anti-CXCL16 Ab treatment group, whereas 80% died within 72 h in control Ab group. The number of liver-infiltrating T lymphocytes was significantly reduced from 1.01×10^7 to 3.52×10^6/liver, compared with control Ab treatment. CONCLUSION: CXCL16 is involved in immunological liver injury by regulating T lymphocyte infiltration in liver tissue.
文摘Hepatitis C virus (HCV) has been recognized to be both a hepato- and lymphotropic virus. HCV lymphotropism represents an essential lap in the pathogenesis of virus-related autoimmune and lymphoproliferative disorders, ranging from clonal expansion of B-cells with organ-and non-organ-specific autoantibody production up to overt non-Hodgkin's lymphoma along a continuous step-by-step model of B-cell lymphomagenesis, where the intermediated mixed cryoglobulinemia could be considered as a stage of suppressible antigen-driven lymphoproliferation. HCV infection of lymphoid ceils could set up privileged reservoirs able to interfere with the host viral clearance efficiency and may be implicated in viral recurrence after apparently successful antiviral therapy. The HCV long-lasting extrahepatic replicative state generates an abnormal systemic immunological response, easily detectable by searching simple laboratory and clinical parameters, mainly represented by vasculitis-like skin features and hypocomplementemia.The presence or absence of this hypersensitivity pattern seems to correlate with the antiviral response and could be identified as a novel immunological cofactor. Further research is required to fully verify the real impact on therapeutic choice/regimen.

文摘Objective:To investigate the immunological effect of Vernonia amygdalina(V.amygdalina) leaf extract and immunace on HIV infected patients taking highly active antiretrwiral therapy. Methods:Fresh V.amygdalina leaves were collected within Nsukka area in Enugu State.The leaves were rinsed with distilled water.Two handful of cleaned fresh leaves were soaked in 200 mL water and squeezed gently by hand to a mixture.Clients were divided into four groups and each group was given different combination.They took the medication for four weeks.The immune effect was tested against marketed immune booster in some retroviral clients.Results:The mean absolute CD4 count was increased in the client who took the extract or supplement.And the clients who took both the extract and supplement had a greater increase in the CD4 count.The increased CD4 was significant as compared with the control group(P<0.05).The skin rashes were also improved in the entire groups.Conclusions:It can be concluded that the aqueous extract of V.amygdalina and immunace or both have immunological effect on HIV infected patients. Therefore,we suggest that the V.amygdalina extract or immunace or both could be used as adjuvant in the management of HIV/AIDS clients.
文摘Many factors, such as environmental, microbial and endogenous stress, antigen localization, can trigger the immunological events that affect the ending of the diverse spectrum of ocular disorders. Significant advances in understanding of immunological and molecular mechanisms have been researched to improve the diagnosis and therapy for patients with ocular inflammatory diseases. Some kinds of ocular diseases are inadequately responsive to current medications;therefore, immunotherapy may be a potential choice as an alternative or adjunctive treatment, even in the prophylactic setting. This article first provides an overview of the immunological and molecular mechanisms concerning several typical and common ocular diseases; second, the functions of immunological roles in some of systemic autoimmunity will be discussed; third, we will provide a summary of the mechanisms that dictate immune cell trafficking to ocular local microenvironment in response to inflammation.
文摘To evaluate the effects of different extract of Pseudostellaria heterophylla on immunological function in mice based on Meta-analysis and Network meta-analysis,the article retrieved domestic and foreign databases according to the"PICO"retrieval strategy,and used Stata and ADDIS software for Meta analysis.A total of 6 reports,10 randomised controlled trials(RCTs)were eventually involved.Meta analysis results showed that:compared with the control group,the experimental group of polysaccharide,saponin and crude extract were better than that of the control(P<0.05),which significantly improved the immunological function in mice.Network meta-analysis results showed that the saponin had the best effect on the increase of phagocytic index and the differences were statistically significant[MD=1.50,95%CI(0.71,2.28),P<0.05];The polysaccharide and saponin had better effect on the increase of spleen index than the control and crude extract,and the differences were statistically significant[MD=0.77,95%CI(0.27,1.31),P<0.05],[MD=0.71,95%CI(0.01,1.50),P<0.05];the polysaccharide had the best effect on the increase of thymus index and the differences were statistically significant[MD=0.70,95%CI(0.11,1.34),P<0.05].The rank probability showed that the saponin of Pseudostellaria heterophylla had the maximum probability to increase phagocytic index of mice;the probability for the components of Pseudostellaria heterophylla increasing spleen index of mice was in the order of crude extract>polysaccharide>saponin;the probability for the components of Pseudostellaria heterophylla increasing thymus index of mice was in the order of saponin>polysaccharide>crude extract.Based on the available evidence,the extract of Pseudostellaria heterophylla could improve the immunity of mice,and the clinical effect of polysaccharide and saponin was the best,which provided a more valuable scientific reference for evidencing that the polysaccharide and saponin of Pseudostellaria heterophylla was the effective components for improving immunological function,and also was conducive to the proper further development of Pseudostellaria heterophylla resources.

The immune compounds in ovary and endometrium were less in the treatment group than that in the model and control group. Conclusion By regulating immunological system, Traditional Chinese Medicine compound mixfang Mianbu Fang lowers AsAb in the circulation system and special organs, eliminates immunological compound, repairs tissue impairment and increases pregnancy of female mice.
文摘This study was aimed to evaluate the long-term effects of telbivudine(Ld T) in the treatment of chronic hepatitis B(CHB) and HBV-related liver cirrhosis(LC) and to observe the changes of immunological responses during Ld T treatment. Clinical data of 80 CHB and 28 HBV-related LC patients who were administered with Ld T for 108 weeks and followed up were retrospectively analyzed. The liver function indicators including ALT, AST and γ-GT, HBV DNA copy number in serum and the rates of hepatitis B e antigen(HBe Ag) seroconversion were analyzed before and 12, 24, 36, 48, 60, 72, 84, 96 and 108 weeks after Ld T treatment in CHB and LC groups. Four serum fibrosis-related markers, including hyaluronic acid(HA), human laminin(LN), human type Ⅳ collagen(Ⅳ-C) and human N-terminal procollagen Ⅲ peptide(PC-Ⅲ), were detected before and after Ld T treatment in LC group. The results showed favorable viral suppression and biochemical responses after treatment with Ld T for 12 weeks, and a high rate of virological and biochemical control was maintained during the course of 108-week treatment in both CHB and LC groups. The four fibrosis-related markers, especially HA and LN, were down-regulated to some degrees in LC group. Moreover, Ld T treatment led to the fluctuation of the circulating interferon-γ(IFN-γ) and interleukin-10(IL-10) levels at different time points in CHB group. It was concluded that Ld T could favorably lead to the virological suppression and biochemical remission. Besides, IFN-γ and IL-10 may represent a suitable and effective predictor of responsiveness during Ld T therapy.
文摘BACKGROUND Hepatitis B virus(HBV)infection is a major factor responsible for HBV+hepatocellular carcinoma(HCC).AIM An immunological classification of HBV+HCC may provide both biological insights and clinical implications for this disease.METHODS Based on the enrichment of 23 immune signatures,we identified two immunespecific subtypes(Imm-H and Imm-L)of HBV+HCC by unsupervised clustering.We showed that this subtyping method was reproducible and predictable by analyzing three different datasets.RESULTS Compared to Imm-L,Imm-H displayed stronger immunity,more stromal components,lower tumor purity,lower stemness and intratumor heterogeneity,lower-level copy number alterations,higher global methylation level,and better overall and disease-free survival prognosis.Besides immune-related pathways,stromal pathways(ECM receptor interaction,focal adhesion,and regulation of actin cytoskeleton)and neuro-related pathways(neuroactive ligand-receptor interaction,and prion diseases)were more highly enriched in Imm-H than in Imm-L.We identified nine proteins differentially expressed between Imm-H and Imm-L,of which MYH11,PDCD4,Dvl3,and Syk were upregulated in Imm-H,while PCNA,Acetyl-a-Tubulin-Lys40,ER-α_pS118,Cyclin E2,andβ-Catenin were upregulated in Imm-L.CONCLUSION Our data suggest that“hot”tumors have a better prognosis than“cold”tumors in HBV+HCC and that“hot”tumors respond better to immunotherapy.
文摘To observe the histological and immunohistochemical changes caused by of Traditional Chinese Medicine——Mianbu Fang (Immunological Infertility Healing Mixture) in testis and epididymus of male mice with immunological infertility induced by antisperm antibody (AsAb). Materials & Methods Models of mice with immunological infertility were used by injection of mice sperm. These mice were treated with Mianbu Ⅰ, Mianbu Ⅱ or Prednisone Acetates. The characteristics on histology and immunohistochemistry of mice were analyzed. Results High level of AsAb was detected in serum and seminal vesicle plasma of model mice after treatment. Immune compounds mostly deposited in limiting membrane of seminiferous tubules, spermatogonium and epithelia of epididymis ducts. The number of spermatogenic cells per convoluted seminiferous tubule decreased. However, the Chinese medicine could significantly reduce the level of AsAb, or even eliminate the antibodies and clear out the immune compounds and increase the number of spermatogenic cells of seminiferous tubules. Conclusion Chinese Medicine Mianbu Ⅰand Ⅱ can regulate, absorb and clear out circulation and partial AsAb, as well as immunological compound. Hence, they can increase the number of spermatogenic cells of seminiferous tubules and increase the pregnancy of mice.
文摘Objective: To explore the effect of Yanhuning in combined with azithromycin on the inflammatory cytokines and immunological function in children with mycoplasma pneumonia. Methods: A total of 130 children with mycoplasma pneumonia were included in the study and randomized into the treatment group (n=65) and the control group (n=65). The patients in the control group were given azithromycin. On the above basis, the patients in the treatment group were given Yanhuning. The patients in the two groups were continuously treated for 7 d. The levels of serum inflammatory cytokines and immunological function indicators before and after treatment in the two groups were detected and compared. Results: When compared with before treatment, the serum IL-2 level after treatment in the two groups was significantly elevated, while IL-4, IL-10, IL-13, IL-6, TNF-α, and IFN-γ levels were significantly reduced;moreover, the improvement in the treatment group was significantly superior to that in the control group. When compared with before treatment, CD3+, CD4+, and CD4+/CD8+ after treatment in the two groups were significantly elevated, and those in the treatment group were significantly higher than those in the control group, while CD8+ was significantly reduced, but the comparison between the two groups was not statistically significant. When compared with before treatment, RBC-C3bR after treatment in the two groups was significantly elevated, while RBC-ICR was significantly reduced;moreover, the improvement in the treatment group was significantly superior to that in the control group. Conclusions: Yanhuning in combined with azithromycin in the treatment of mycoplasma pneumonia in children can significantly enhance the immunological function, and reduce the inflammatory reaction, with an effect significantly superior to that by single application of azithromycin.
