It has always been controversial whether a single allergen performs better than multiple allergens in polysensitized patients during the allergen-specific immunotherapy.This study aimed to examine the clinical efficacy of single-allergen sublingual immunotherapy (SLIT) versus multi-allergen subcutaneous immunotherapy (SCIT) and to discover the change of the biomarker IL-4 after 1-year immunotherapy in polysensitized children aged 6-13 years with allergic rhinitis (AR) induced by house dust mites (HDMs).The AR polysensitized children (n=78) were randomly divided into two groups:SLIT group and SCIT group.Patients in the SLIT group sublingually received a single HDM extract and those in the SCIT group were subcutaneously given multiple-allergen extracts (HDM in combination with other clinically relevant allergen extracts).Before and 1 year after the allergen-specific immunotherapy (ASIT),the total nasal symptom scores (TNSS),total medication scores (TMS) and IL-4 levels in peripheral blood mononuclear cells (PBMCs) were compared respectively between the two groups.The results showed that the TNSS were greatly improved,and the TMS and IL-4 levels were significantly decreased after 1-year ASIT in both groups (SLIT group:P＜0.001;SCIT group:P＜0.001).There were no significant differences in any outcome measures between the two groups (for TNSS:P＞0.05;for TMS:P＞0.05;for IL-4 levels:P＞0.05).It was concluded that the clinical efficacy of single-allergen SLIT is comparable with that of multi-allergen SCIT in 6-13-year-old children with HDM-induced AR.

ObjectiveTo observe the effects of acupuncture combined with massage on shoulder subluxation and motor function recovery of the upper extremities in patients with hemiplegia after stroke.Methods60 hemiplegic patients were randomly divided into two groups for treatment with acupuncture cooperates with massage or usual rehabilition, respectively. The recovery of the patient's shoulder subluxation and movement function of upper extremities were evaluated 2 months after treatment. ResultsThe shoulder subluxation and movement function of the upper extremities were improved after treatment with both therapies (P<0.01), and acupuncture cooperates with massage showed better effect (P<0.01). ConclusionAcupuncture cooperates with massage can facilitate the recovery of shoulder subluxation and motor function of the upper extremities after hemiplegia.

Objective To investigate significance of interferon-γ/interleukin-4(IFN-γ/IL-4) and macrophages in uterus in early embryo loss (or resorption), and to elucidate the anti-abortive effect and the immunological modulation at maternal-fetal interface with quercetin and bornvl acetate. Methods Lipopolysaccharide (LPS)(0.10μg/mouse)was injected via tail vein in order to induce abortion in 7-day-gestation mice which received quercetin and bornvl acetate at days 4-7 of gestation. Levels of IFN-γ and IL-4 in uterus lysate supernatant were measured using enzyme-linked immuno-absorbent assay (ELISA), and uterine macrophages of each group ( n =10) were detected by immunohistochemistry. Results The amount of macrophages was much higher in the uteri of LPS-induced abortion mice than that in control mice. The abortion rate of mouse declined to certain level. The therapy of quercetin combined with bornyl acetate reversed LPS-induced abortion. Conclusion The increase of IFN-γ/IL-4 and the amount of macrophages in the LPS-treated mouse uterus is associated with the embryo loss, and quercetin and bornyl acetate have the anti-abortive effect through modulation of maternal-fetal interface immunity balance.

In this paper, absorption and pharmacokinetic study of Radix Rehmanniae was studied by liquid chromatography coupled with mass spectrometry method after oral administration to rats. By comparing the chromatograms of ultraviolet, full scan, extracted ion and selective reaction monitoring (SRM) of standard solution, Radix Rehmanniae, blank plasma and rat plasma post drug administration, catalpol and ajugol were found to be the main compounds absorbed from Radix Rehmanniae. Plasma concentrations of aucubin, dihydrocatalpol, rehmannioside A (or rehmannioside B/ melittoside) and rehmannioside D were very low. Quantitative method for catalpol and aucubin and semi-quantitative method for other compounds in rat plasma were established. The pharmacokinetic study of those absorbed components was conducted after oral administration of 6 g x kg(-1) Radix Rehmanniae water extract to rats. Cmax, t(1/2) and AUC(0-infinity) of catalpol and ajugol were (2349.05 +/- 1438.34) and (104.25 +/- 82.05) ng x mL(-1), (0.86 +/- 0.32) and (0.96 +/- 0.37) h, (4407.58 +/- 2734.89) and (226.66 +/- 188.38) ng x h x mL(-1), respectively. tmax was at 1.00 h for catalpol and ajugol. Both catalpol and ajugol were absorbed and excreted rapidly.

Objective To investigate prophylaxis and therapy of early complications following relatives' partial live small bowel transplantation.Methods Four relatives' partial live small bowel transplantations were carried out.Among the 4 patients,there were 3 cases of short intestine syn- drome and one case of non-function of small bowel caused by the absence of nerve ganglion of small in- testine.More than 4 antigens of HLA were completely matched between donators and receptors.In- testines of donators were got from terminal ileum with the length of (150?10) cm.After operations, tacrolimus (FK506),mycophenolate mofetil (MMF),and methylprednisolone were used to prevent rejections.Measures such as use of anticoagulation,improving microcirculation and albumin infusion, aimed at regulating the function of blood coagulation and preventing bleeding and formation of thrombus at anastomotic stoma;famotidine and omeprazole were used to prevent irritable ulcer;use of the third generation of cephalosporins antibiotics,ganciclovir and fluconazol could prevent bacteria,vi- rus and eumycete infections;disinfection and care of easily-infected organs were emphasized;receptors were encouraged to get out of their beds to move frequently;glutamine and enteral nutrition were used early to promote recovery of intestinal function.Results Three days after operation,one patient's lung was infected with baumanii,and the infection had been under control after being treated with the third generation cephalosporins antibiotics;five days after operation,haematoma was detected on an- other patient and was cleared through the second operations growth of eumycete was found in 2 pa- tients' excretion and secretion from enteron,and their situations were improved with fluconazol;acute rejections of the 4 patients were detected 20 days after operation and reversed by the increased use of FK506 combined with methylprednisolone.Among the 4 patients,2 of them have survived for a long time,and the first patient has survived for 6 years and 8 months till now and the other one for 3 years and 2 months;furthermore,other 2 patients respectively died of infections 5 months and 35 days after the operations.Conclusion Because of special constitution of intestine,early complications of rela- tives' partial live small intestine transplantation are frequent and complicated.Therefore,prophylaxis and therapy of early complications are crucial to the success of the transplantation.

BACKGROUND:Retinoic acid is the most promising inducer for neuroblastoma minimal residual lesion, and it can induce cel differentiationin vivo, accompanied by reducing tumor cel proliferation.
OBJECTIVE:To study the effect of nanoparticle labeling on biological characteristics of neuroblastoma stem cels, and the role of 13-cis retinoic acid to induce differentiation of neuroblastoma stem cels.
METHODS:Neuroblastoma stem cels were isolated and culturedin vitro using serum-free suspension culture method, labeled with polylysine-modified γ-Fe2O3 nanoparticles and induced in culture medium containing 13-cis retinoic acid. RT-PCR was used to detect the expression of Oct-4 before and after labeling as wel as before and after induction. Immunofluorescence method was used to detect the expression of nestin before and after labeling as wel as before and after induction.
RESULTS AND CONCLUSION:Neuroblastoma stem cels were successfuly cultured in the bone marrow samples from 5 of 20 cases. Polylysine-modified γ-Fe2O3 nanoparticle labeling did no influence the viability and proliferation ability of neuroblastoma stem cels, and also had no effect on Oct-4 mRNA and nestin expression. After cultured in the culture medium containing 13-cis retinoic acid, the cel shape changed and the growth rate slowed down. Moreover, the expression of Oct-4 mRNA and nestin was gradualy reduced. These findings indicate that polylysine-modified gamma-Fe2O3 nanoparticles can be used to label neuroblastoma stem cels, and 13-cis retinoic acid can induce the differentiation of neuroblastoma stem cels.
