Objective To investigate the effects of ketogenic diet ( KD) treatment on helper T cell subsets in children with intractable epilepsy( IP) . Methods Thirty-five children with IP and eighteen age-matched healthy subjects were enrolled in this study.The percentages of CD3+CD8-IFN-γ+( Th1 ) cells, CD3+CD8-IL-17A+(Th17) cells and CD4+CD25+Foxp3+(Treg) cells were analyzed by flow cytometry.Re-al-time PCR assay was performed to evaluate the expression of T-bet, ROR-γ, IFN-γ, IL-17A and peroxi-some proliferator activated receptorγ( PPAR-γ) at mRNA level in CD4+CD25-T cells and the transcription-al levels of Foxp3, GITR, CTLA-4 and PPAR-γin CD4+CD25+T cells.The concentrations of cyclooxygen-ases-2 (COX-2) and prostaglandin F2a (PGF2α) in plasma samples were measured by enzyme-linked im-munosorbent assay.The expression of IL-17A and IFN-γin plasma samples were detected by using cytomet-ricbeadarray(CBA).Results (1)ThepercentagesofTregcellsinperipheralbloodsamplesfrompa-tients with IP were lower than those in healthy subjects (P<0.05), which were significantly increased with the treatment of KD (P<0.05).The percentages of Th17 and Th1 cells in patients with IP were significantly higher than those in healthy children (P<0.05), but were remarkably decreased with the treatment of KD (P<0.05).Patients with IP showed decreased transcriptional levels of Foxp3, GITR and CTLA-4 in CD4+CD25+T cells as compared with healthy controls, but were up-regulated with the treatment of KD.The ex-pression of transcription factors including T-bet, ROR-γ, IFN-γand IL-17A in CD4+CD25-T cells in pa-tients with IP were higher than those in healthy subjects and were down-regulated after the treatment of KD (P<0.05).(2) The expression of PPAR-γat mRNA level in CD4+CD25-T and CD4+CD25+T cells were decreased in patients with IP as compared with those in heathy controls, but were increased after the treat-ment of KD (P<0.05).Correlation analysis showed that Treg cells had a positive correlation with PPAR-γ(r=0.61, P<0.05).However, the Th1 and Th17 cells were negatively correlated with PPAR-γ[Th1 (r=-0.54, P<0.05), Th17 (r=-0.64, P<0.05) ].(3) The levels of IL-17A and IFN-γin patients with IP were higher than those in healthy controls, but were decreased with KD treatment (P<0.05).The levels of COX-2 and PGF2αin plasma samples from patients with IP were higher than those in healthy controls ( P<0.05).A negative correlation was observed between COX-2 and PPAR-γ(r=-0.571, P<0.05). Moreover, PGF2αand PPAR-γhad a negative correlation as well (r=-0.586, P<0.05).Conclusion The treatment of KD might enhance the expression of PPAR-γthrough inhibiting the products of oxidative stress such as COX-2 and PGF2α, resulting in the rebalance of Th cell subsets and reduced expression of in-flammatory cytokines.

Objective To explore the genuineness of Exocarpium Citri Grandis(ECG) from Huazhou city of Guangdong province.Methods We used the method of high performance liquid chromatography to detect the naringin content in ECG from different producing areas of Huazhou city.Random amplified polymorphic DNA analysis was used for the examination of genetic distance,and plasma-atomic emission spectrometry for the detection of soil elemental abundance of 8 elements such as aluminium(Al),kalium(K),calcium(Ca),ferrum(Fe),titanium(Ti),boron(B),magnesium(Mg),and manganese(Ma).The correlation of the above three parameters was analyzed by statistical software SPSS 11.5.Results Ca abundance in the surface soil layer had an obvious effect on the content of naringin,and the difference of Al and K abundance in subsoil layer was correlated with the genetic distance of ECG.Conclusion The genuineness of ECG is probably related with the abundance of phlopopitum in the soil of producing areas of Huazhou city.

Objective To study the expression and value of CXCR1 and CXCR2 on neutrophils, CD14~+ monocytes and CD3~+ T lymphocytes of peripberol blood of ankylosing spondylitis(AS)patients and to investigate the correlation between CXCR1,CXCR2 and disease activity.Methods A case control study was designed and enrolled 30 active AS,30 active rheumatoid arthritis(RA)and 30 healthy controls.The levels of CXCR1 and CXCR2 expression on neutrophils,CD3~+ T cells and CD14~+ monocytes of peripheral blood of the patients and healthy controls enrolled were measured and analyzed by flow cytometry by measuring the mean fluorescence intensity(MFI)channel.The correlations between the level of CXCR1 and CXCR2 anti disease activity or functional index of AS such as BASDAI,BASF1,ESR and CRP were analyzed.Results The MFI of CXCR1 expression on CD3~+ T lymphocytes of peripheral blood was significantly higher in AS patients (41?24)than that in RA patients(18?10)and healthy controls(19?7)(P

Objective To evaluate the preventive effects of Haishe capsules on the conversion of amnestic mild cognitive impairment (aMCI) to Alzheimer's disease(AD).Methods Patients (n=120) with aMCI from our department were recruited and randomly divided into the treatment group and the control group (n=60 in each group).The treatment group was given 0.9 gram of Haishe capsules three times a day while the control group received no drug treatment.Data on the conversion ratio,memory and cognitive function were comparedbetween the groups in a 24-months follow-up.Results By the end of the study,12 patients in the treatment group and 15 in the control group dropped out.Valid data for 93 patients were available for statistical analysis (48 in the treatment group and 45 in the control group).The number of aMCI patients who converted to AD was 6,with a conversion ratio of 12.5% (6/48);and the number of patients who went through conversion in the control group was 13,with a conversion ratio of 28.8% (13/45).The difference in conversion between the two groups was statistically significant (x2 =3.83,P<0.05).After 24 months,MMSE scores for the treatment group (25.52± 1.07) had no significant change compared with baseline levels,while MMSE scores for the control group decreased significantly(24.75--1.49) and were markedly lower than thosefor the treatment group (t=2.85,P<0.05).MoCA scores for the treatment group (19.39 ±2.01) did not show decline until the end of the study,while those for the control group started to decrease about half way through the study and were lower than scores for the treatment group (t =2.41,P<0.05).Compared with baseline levels,ADAS-Cogscores for the treatment group (7.62± 1.06) did not increase significantly during the course of the study.ADAS-Cogscores forthe control group were higher at both half way (7.70±0.75) and the end of the study (8.18±0.80)than base line levels,and there was a statistically significant difference in end-of-study ADAS-Cog scores between the two groups(t =-2.6,P< 0.05).Conclusions Haishe capsules not only effectively maintain memory and cognitive function,but also delay the conversion from aMCI to AD.

OBJECTIVETo investigate the relationship between coxsackievirus infection and type 1 diabetes mellitus (T1DM), and observe the changes of T lymphocyte subsets in the development of T1DM.
METHODSWe detected Coxsackievirus RNA by reverse transcription PCR, and measured the change in T-lymphocyte subsets by flow cytometry in 22 cases of newly diagnosed T1DM (group I), 30 patients with diabetes for some time (group II), and 30 healthy subjects (group III).
RESULTSThe positivity rate of coxsackie virus RNA in groups I, II, and III was 55.55%, 23.33%, and 6.67%, respectively, showing a significant difference among the 3 groups (P<0.01). Patients with upper respiratory tract infection had a higher positivity rate for coxsackie virus RNA than those without upper respiratory tract infection in group I (P<0.05). Compared with the control group, the percentage of CD3, CD4 and CD4/CD8 ratio decreased significantly in groups I and II (P<0.01 or P<0.05). CD3, CD4 and CD4/CD8 tended to increase in group II in comparison with group I, and there was an significant difference in CD3 and CD4 between the two groups (P<0.01 or P<0.05). Compared with the control group and CVBRNA-negative group, CVBRNA-positive group showed significantly lowered CD3, CD4, CD8 and CD4/CD8 (P<0.01 or P<0.05).
CONCLUSIONThe occurrence and development of type 1 diabetes is closely related to coxsackie virus infection, and the changes in T lymphocyte subsets serves as a probable mechanism of its pathogenicity.
