RESUMEN

Allergic rhinitis (AR) is an allergic disease of nasal mucosa, currently the consensus has been reached that there is a Th1/Th2 imbalance in AR′s pathogenesis, meanwhile there are defects in the number and/or function of Treg cells. Mesenchymal stem cells (MSCs) have characteristics of multiple differentiation potential, low immunogenicity and immunomodulation function, which can be migrated and implanted into the nasal inflammatory mucosal, recovering the Th1/Th2 immune balance and up-regulate the Treg cells by immunomodulatory function to improve AR. For the present, the treatment of AR by MSCs is basically at the animal experiment stage. This paper reviews the progress of MSCs in AR′s treatment and provides a basis for the clinical treatment of MSCs.

RESUMEN

Objective: To investigate the clinical efficacy and safety of Shure granule combined with estradiol valerate in the prevention of intrauterine adhesions in induced abortion.Methods: Selected 240 cases of artificial abortion were divided into observation group and control group according to the order of admission, 120 cases each.Patients in the control group were treated with estradiol valerate.The observation group was treated with Shure granules on the basis of the control group;The treatment time was 3 weeks.The time of vaginal bleeding and the amount of bleeding, menstruation, retidal and adverse drug reactions of the two groups were observed;The levels of serum fibronectin (FN), human laminin (LN) and vascular endothelial growth factor (VEGF) were compared between the two groups before and after the operation.The adhesion of the 12 cases in the two cases was compared.Results: The time of vaginal bleeding and the amount of bleeding in the observation group were significantly better than those in the control group (P<0.05), and the normal rate of menstrual volume was higher than that of the control group (P<0.05).The serum levels of FN, LN and VEGF in the observation group were significantly lower than those in the control group 2 weeks after the operation (P<0.05).After 12 months, the incidence of intrauterine adhesions in the observation group was significantly lower than that in the control group (P<0.05).There was no significant difference in the incidence of adverse drug reactions between the two groups (P>0.05).Conclusion: The efficacy of Shure granule combined with estradiol valerate in preventing intrauterine adhesions in induced abortion is superior to estradiol valerate alone.

RESUMEN

Objective@#To investigate the correlation between the proliferation inhibition effect of glucocorticoid (GC) on peripheral blood mononuclear cell (PBMC) and the pure tone average (PTA) improvement in SSNHL patients.@*Methods@#Sixty inpatients with SSNHL were included from July 2013 to October 2015 in Nanjing Drum Tower Hospital, Medical School of Nanjing University. Peripheral venous blood was collected before receiving treatment, then the PBMC was isolated for GC proliferation inhibition. PBMCs of each patient were cultivated into 4 groups: Group A: PBMCs+ Medium; Group B: PBMCs+ Medium+ lipopolysaccharide (LPS, 1 μmol/L); Group C: PBMCs+ Medium+ LPS+ Dexamethasone; Group D: Medium. PBMCs were maintained in a humidified 5% CO2 atmosphere at 37°C and were observed after 24 hours. 5-diphenyltetrazolium bromide (MTT) was used to measure PBMC proliferation inhibition rate. The PBMC proliferation inhibition rates were calculated according to the absorbance at 490 nm wavelength under a microtiter plate reader. Independent sample t tests of PBMC proliferation inhibition rate were performed between different groups. χ2 tests were performed between gender, affected ear side, accompanied by vertigo or not, audiometric curve, time period from onset to treatment, PBMC proliferation inhibition rate and the improvement of pure tone average (PTA). Linear correlation analyses were performed between PBMC proliferation inhibition rate, the time period from onset to treatment and the hearing improvement.@*Results@#The proliferation inhibition effect of GC on PBMC varied significantly among patients. The PBMC proliferation inhibition rate in GC insensitive group was lower than that in GC sensitive group (26.72%±21.82% vs 64.44%±25.48%, t=6.113, P<0.05). The PBMC proliferation inhibition rate in refractory group was lower than that in initial group (40.93%±28.57% vs 57.04%±31.19%, t=2.035, P=0.046). There was no statistical significance between gender, affected ear side, accompanied by vertigo or not, audiometric curve and the hearing improvement (χ2 value was 2.320, 0.031, 2.143, 0.106, respectively, all P>0.05). Both in initial group and refractory group, the linear correlation analyses showed a significant positive correlation between PBMC proliferation inhibition rate and the PTA improvement (r value was 0.615, 0.657, respectively, all P<0.05), as well as a significant negative correlation between time period from onset to treatment and the PTA improvement(r value was -0.542, 0.370, respectively, all P<0.05).@*Conclusions@#The proliferation inhibition rate of PBMC in vitro by GC is correlated with patients′ hearing improvement. The proliferation inhibition test might be used to predict the sensitivity to GC treatment and be helpful for individualized treatment of SSNHLin clinical practice.
