ABSTRACT
Dacryocystitis is a common ophthalmic disease, and the main treatment of it is to abandon the obstructed nasolacrimal duct and create a new lacrimal drainage pathway through implanting a tube.For now, its pathogenesis is understood very limitedly.It is widely accepted that many factors take part in its occurrence, among which obstruction and infection play important roles.Recent researches have shown that there is lacrimal drainage-associated lymphoid tissue (LDALT) which changes remarkably in dacryocystitis, and significant differences in cytokines expression levels in tears between dacryocystitis patients and normal control have been found.In addition, the lacrimal duct has reactions similar to immune rejection to the silicone tube.All of these indicate that immune factors participate in the pathogenesis of dacryocystitis.Changes of immune tissue and macromolecular substances including the LDALT, cytokines, local tissue and cytokines after tube implantation were reviewed to analyze the changes and possible roles of immune factors in the pathogenesis of dacryocystitis.
ABSTRACT
Objective:To investigate the effect of human tumor suppressor folliculin (FLCN) on the expression of melanocyte chemokines (MC) mediated by immune factors in vitiligo.Methods:The MC of vitiligo patients that received autologous melanocyte transplantation in the Department of Dermatology, Hangzhou Third People′s Hospital from January to April 2019 were collected. The blister fluid of the white spot and the normal part was taken. Western blot was used to analyze the expression difference of MC and FLCN protein in normal, vitiligo patients and that induced by immune factors; FLCN shRNA lentivirus was constructed by shRNA and transfected into normal MC (FLCN shRNA MC) to interfere with the expression of silenced FLCN gene. The effect of immune factors on chemokines in FLCN shRNA MC was detected by ELISA.Results:The results of Western blot showed that FLCN protein was highly expressed in melanocytes of vitiligo patients, immune factors stimulated FLCN protein expression in normal melanocytes significantly increased ( t=1.27; P<0.001), chemokine CXCL10 and CCL20 also significantly increased ( t=104.53 and 60.21, respectively; P<0.001). The expression of FLCN in FLCN shRNA MC was significantly decreased ( F=1.95, P<0.001); and the high expression of CXCL10 and CCL20 induced by immune factors was significantly inhibited ( F=93.676 and 74.096, all P<0.001). Conclusions:Immune factors can stimulate the expression of CXCL10 and CCL20, which are closely related to vitiligo, while FLCN is a key protein involved in immune factors inducing melanocyte chemokine expression.
ABSTRACT
Major histocompatibility complex (MHC) polymorphisms are associated with animal and human diseases. However, only a few studies have reported an association between MHC polymorphisms and mycoplasma ovipneumonia (MO). In the present study, three resistance/susceptibility genotypes associated with MO were identified by polymerase chain reaction-restriction fragment length polymorphism genotyping, assessing the clinical and pathological features, and examining the immune factors. The current results showed that MvaI bb and HaeIII ee were dominant genotypes in the susceptible Hu population, while MO-resistant populations, Dorper and D 9 H hybrids, were dominated by the MvaI cc and HaeIII dd genotypes, suggesting that MvaI cc and HaeIII dd genotypes might be associated with the trait of MO resistance. Further, the clinical symptoms and pathological morphology in the susceptibility group infected with MO were more severe than those in the resistant groups infected similarly. The data on the changes in the immune factor responses were utilized to deduce the molecular mechanism underlying the MO resistance/susceptibility. The results showed that the susceptible genotypes promote the inflammatory responses by inducing a high expression of TNFa, IFNc, IL-4, IL-6, and IL-1b, while the resistant genotypes inhibit the inflammatory response by increasing the expression of IL-2 and IL-10 significantly. This finding would provide the theoretical guidance for propagating sheep breeds that are highly resistant to MO.
ABSTRACT
Aim To investigate the effect of acteoside on the changes of immune function and aging process in SAMP8 mice via detecting the proportion of immune cells and the changes of immune factors. Methods Sixty male healthy SAMP8 mice and twelve SAMR1 mice were randomly divided into six groups. They were administered by gavage once a day for 90 days. Aging scoring test was conducted regularly. The immune cells and immune factors in plasma and liver were detected. Results Compared with model group, acteoside could increase CD4+lymphocytes in SAMP8 mice and effectively inhibit the increase of CD8+lymphocytes; it played a greater role in spleen than in peripheral blood. At the same time, Thl/Th2 was significantly reduced in model group, and the ratio of Thl/Th2 factor increased in low and medium dose group. Conclusions Acteoside can increase the number of helper lymphocytes, effectively inhibit the increase of killer lymphocytes, and regulate the dynamic balance of Th1 and Th2 type immune inflammatory factors in SAMP8 mice, so as to improve the immune function of the body and delay the aging process of the body.
ABSTRACT
OBJECTIVE@#To investigate the effects of Shoutai pills (a traditional Chinese medicinal preparation) on immune functions and oxidative stress in pregnant rats exposed to di(2-ethylhexyl) phthalate (DEHP).@*METHODS@#Thirty-six mature female SD rats were randomly divided into 3 groups (=12). After pregnancy was confirmed, the rats were given 10 mL/kg corn oil +10 mL/kg saline (control group), 500 mg/kg DEHP+10 mL/kg saline (model group), and 500 mg/kg DEHP+10 mL/kg Shoutai pills (treatment group). At 19 days of gestation, the rats were sacrificed and the fetal rats were weighed and the numbers of live and stillborn fetal rats were recorded. Serum levels of interleukin-6 (IL-6), interleukin-2 (IL-2), tumor necrosis factor-ɑ (TNF-ɑ), estradiol (E2) and progesterone (P) levels were detected. The appearance, color and quality of the placenta in each group were recorded, and the placental tissues were examined pathologically. The total antioxidant capacity (T-AOC), superoxide dismutase (SOD), glutathione peroxidase (GSH- Px), catalase (CAT), reactive oxygen species (ROS) and malondialdehyde (MDA) in the placental tissues were measured.@*RESULTS@#Compared with the control group, the rats with DEHP exposure showed slow weight gain in the middle and late gestation period and significantly lower fetal weight ( < 0.05) with lowered serum levels of IL-2, IL-6 and TNF-ɑ, increased estradiol level ( < 0.05), decreased placental T-AOC, GSH-Px, SOD and CAT levels, and increased ROS and MDA levels ( < 0.01). Compared with the model group, the rats treated with Shoutai pills had significantly increased weight gain in mid and late pregnancy and greater fetal weight ( < 0.05) with significantly increased serum IL-2 and IL-6 levels, decreased estradiol level ( < 0.05), slightly increased TNF-ɑ expression (> 0.05), increased placenta T-AOC, GSH- Px and CAT levels, decreased MDA level ( < 0.05), and slightly increased SOD and decreased ROS levels (>0.05). No significant difference was found in progesterone levels among the groups (>0.05). HE staining showed that the trophoblast in the placental tissue sponge in the model group was loose and irregular with numerous vacuoles. In the treatment group, the structure of the placenta remained intact with clearly visible labyrinth zone, sponge trophoblast and giant cell trophoblast, and the cell distribution in each layer was better than that in the model group.@*CONCLUSIONS@#Shoutai pills can regulate the immune function of DEHP-exposed pregnant rats possibly by antagonizing the estrogenlike effect of DEHP and regulating serum immune factors; Shoutai pills can also reduce placental tissue damage and improve pregnancy outcome by correcting DEHP-induced imbalance of oxidative stress in the placental tissues.

Erythrocyte sedimentation rate, rheumatoid factor, anti-cyclic citrulline peptide antibody and C-reactive protein were detected in the serum of subjects in RA group and CP+RA group. Correlation analysis was conducted between MMP-3 expression level and periodontal indices amongst 4 groups. The results were statistically analyzed using the SPSS 20.0 software package.@*Results@#The indices of CAL [(4.12±1.13) mm], SBI (2.58±0.64) and DI-S (2.65±0.69) in CP+RA group were significantly higher than indices of CAL [(3.00±0.00) mm], SBI (2.59±1.05) and DI-S, (2.36±0.49) in CP group (P<0.05); The expression levels of MMP-3 in serum samples of CP+RA group [(1 1645.6±6 903.4) μg/L] and CP group [(9 337.0±6 719.0) μg/L] were significantly higher than that of RA group [(2 389.9±1 320.3) μg/L] and H group [(1 493.5±292.1) μg/L] (P<0.05). The expression level of MMP-3 in gingival crevicular fluid samples of CP+RA group [(164.4±45.3) μg/L] was significantly higher than that of CP group [(84.6±92.5) μg/L], RA group [(49.0±18.1) μg/L] and H group [(20.4±6.3) μg/L] (P<0.05), respectively. The erythrocyte sedimentation rate, rheumatoid factor and anti-cyclic cirullinated peptide antibodies levels in the CP+RA group were significantly higher than those in the RA group (P<0.05). The expression level of MMP-3 in serum is positively correlated with PD (r=0.45, P=0.04) and the expression level of MMP-3 in gingival crevicular fluid is positively correlated with CAL (r=0.58, P<0.01).@*Conclusions@#The levels of MMP-3 in serum and gingival crevicular fluid of patients with RA and CP were significantly increased. MMP-3 may be associated with the development of CP and RA.
ABSTRACT
Objective To explore the immune mechanism in the systemic lupus erythematosus MRL/lpr mice at different months of age, and to provide the basis for research of its pathogenesis. Methods 3-,4-,5- and 6-month old female MRL/lpr mice, and wild type C57 female mice were used in this study, 10 mice per each group. Their organ coefficients were determined. ELISA was performed to detect the serum levels of double stranded DNA(ds-DNA) antibody. The interleukins IL-2,IL-4,IL-17 and tumor necrosis factor-α(TNF-α)in spleen tissue were detected. Flow cytometry was used to assess the content of spleen lymphocyte CD3 cells and CD4/CD8 cell ratio. Results Compared with the 3-month old wild-type C57 mice,the spleen coefficient,the blood concentration of ds-DNA antibody,IL-2 and TNF-α in the 3- to 6-month old MRL/lpr mice were significantly increased(P < 0.05). There was no significant difference between the concentrations of interleukin IL-4(P> 0.05). The blood concentration of IL-17 in the 5- and 6-month old MRL/lpr mice was significantly lower(P < 0.05 or P < 0.01)than that in the 3-month old MRL/lpr mice. The rest indexes of MRL/lpr mice showed no obvious changes or significant difference in the mice at different ages. Compared with the 3-month old C57 mice,the spleen CD3 lymphocyte concentration in the MRL/lpr mice was significantly decreased(P< 0.01). With the increasing age, the CD3 lymphocyte concentration and D4 +/CD8 +cell ratio in the MRL/lpr mice were decreased, however, showing a non-significant difference(P ﹥0.05). Conclusions The data obtained in this study indicate that 3-month old lupus MRL/lpr mice have already immune injury,increasing with the increase of age of the mice.

ABSTRACT
Objective: To investigate the effects and underlying mechanism of polysaccharides from Radix Saplshnikoviae on the immune factors in rats with allergic rhinitis induced by OVA.Methods: Firstly, 0.3mg OVA, 30mg Al(OH)3 and 1ml saline were mixed and intraperitoneally injected for the initial immunization, and then 200μg OVA (4%) was given once a day by nasal dripping since the 15th day for the second immunization to establish the allergic rhinitis model.Fifty SD rats were randomly divided into the allergic rhinitis (AR) model group, the polysaccharides from Radix Saplshnikoviae (600 mg·kg-1, 300mg·kg-1, 150 mg·kg-1) groups, the positive (Biyankang, 400 mg·kg-1) group and the normal control group.After the 14-day intragastric administration, blood was collected from abdominal aorta and serum was obtained.The levels of immune factors and inflammatory factors in serum were examined by radioimmunoassay.Results: The positive group and the polysaccharide groups could inhibit the typical symptoms of allergic rhinitis including sneezing, nasal scratching and running nose in varying degrees, and alleviate the inflammatory reaction symptoms.After the drug intervention, the positive group and the polysaccharide groups could down-regulate the expression of immune cell factors IL-4, TNF-A, VCAM-1 and IL-5, enhance IL-12 and INF-γ expression levels, and suppress the generation and release of inflammation factors IgE, HA, LTC4 and PGD2, and the differences were significant when compared with the model group (P＜0.05).The dose-effect relationship was not too obvious among the polysaccharide from Radix Saposhnikoviae groups respectively at high, medium and low dose, and the high dose group was best among them.Conclusion: The polysaccharides from Radix Saplshnikoviae exhibit curative effect for AR, which can down-regulate the serum levels of IL-4 and IL-5, up-regulate the serum levels of IFN-γ and IL-12, adjust Th1/Th2 lymphocyte subsets balance and body immune response and reduce nasal mucosa allergic inflammation, and the underlying mechanism may be related with reducing the generation and release of immune factors in AR induced by OVA.

Objective:To investigate the relationship between changes of the concentration of IL -12,IL-4,IFN-γwithin cervical local immune microenvironment and cervix infected with HPV 16,58,to understand the prevalence of physical status of HPV 16/58 DNA into the host genome in cervical lesions of different grades and to detect the relation between the integrated state of virus and the progress of cervical lesions.Methods: Detecting 89 cases of cervicovaginal lavage fluid and 140 cytological specimens of the cervix which from patients having had HPV-DNA genotyping assays and coming from the Affiliated Tumor Hospital of Guangxi Medical University from 2012.8 to 2013.5.89 cases of cervicovaginal lavage fluid were divided into 58 cases of HPV16 (+) and 31 cases of HPV58(+).Cytokines IL-12, IL-4, IFN-γin the cervical microenvironment were detected by ELISA assay.140 cases of cervical exfoliated cells were divided into 106 cases of HPV16(+) and 34 cases of HPV58(+).Using qRT-PCR to quantify the copy number of E2 and E6 genes and analyze the physical status of HPV 16/58 DNA according to E2/E6.Results:①The level of IL-4 in HPV16(+) was significantly higher than that in HPV58(+)(P<0.05).The levels of IL-12 and IFN-γwere lower than that in HPV58(+)(P<0.05).②Significant differences of DNA state were found between the groups of HPV 16(+) and HPV58(+)(P<0.05)and the rate of HPV16 DNA integration was significantly larger than that of HPV 58 DNA.Conclusion:The infection of HPV16 and HPV58 not only can lead to reduction of IL-12,IFN-γand increasing of IL-4 in cervical local immune microenvironment but also lead to viral integration in cervical cells,resulting in cervical lesions and cervical cancer through the internal and external changes in cervical cells .HPV16 is more likely to cause cervical cancer tissue than 58.
ABSTRACT
Objective To explore the adjustment of interleukin II combining lifein for CD+4 T lymphocyte, Th1 and Th2 of patients with malignant tumor. Methods CD+4 T lymphocyte were measured by flow cytometer. Th1 lymphocyte and Th2 lymphocyte were measured by ELISA. Thirty- eight patients with malignant tumor were enrolled in the study. Interleukin II were administered at the dose of 500 000 U, i.h Qd, from day 1 to day 5. Lifein were administered at the dose of 10mg/d, i.m Qd, from day 6 to day 21 or form day 6 to day 27. The count of CD+4 T lymphocyte, Th1 lymphocyte and Th2 lymphocyte were studied before treatment, 2 weeks and 1 month after treatment. Conduct ANOYA using SPSS software. Results The expression of CD+4 T lymphocyte in patients as with increase tendency. The counts of Th1 lymphocyte, Th2 lymphocyte and Th1/Th2 were not significantly different after treatment. Conclusions The dose of this treatment could enhance the count of CD+4 T, but it could not adjust the count of Th1 lymphocyte, Th2 lymphocyte. The target of treatment about interleukin II combining lifein for patients with malignant tumor is CD+4 T lymphocyte's other subsets.
