Objective To investigate the long-term prognosis an d recorery of children with juvenile rheumatoid arthritis(JRA).Methods The cases diagnosed JRA in our hospital over the period of 1988～1992 we re followed up for the conditions of disease,the deteriorated joints,the treatme nt and the living conditions of patients.Results Ninty-six ca ses were followed up(involving male 66 cases,female 29 cases,the mean age of on set 8.21?3.17 years )except for a case who died of lymphoma.There were 44 cases with systemic JRA ,2 cases of them died after 7-years onset and 23 cases developed severe destructive arthritis.There were 38 oligoarthritis cases,27 cases of them stiu had active disease during 10-year following-up and 9 cases were diagnosed sacroiliitis.There were 13 polyarthritis and 3 cases of them were RF positive, who had developed severe destructive arthritis.Conclusions The prognosis of juvenile rheumatoid arthritis is not desirable,especially in systemic JRA,whose prognostic factors are related to age of onset,the lasting of fever,the markers of phlegmasia activity and the condition of systemic involvement and treatment.Oligoarthritis about 30 % may develop into ankylosing spondylitis.The probability of destructive arthritis is hi gher in polyarthritis with more RF positive and poor prognosis.

Objective To study if 5-Aza-2’-deoxycytidine along or together with 4-phenylbutyric acid could affect miR-196b expression levels in chronic myeloid leukemia cells .Methods K562 cells were treated with DNA methylation inhibitor 5-Aza-2’-deoxycytidine, histone deacetylase inhibitors 4-phenylbutyric acid separately and the combined treatment with both of them, then expression levels of miR-196b were detected using Real-time PCR.Results The half inhibition concentration of 4-phenylbutyric acid was 1.58mmol/L.Comparing with the expression level of miR-196b in normal human bone marrow cells, the expression levels of miR-196b were significantly lower in Aza group , PBA group and negative control cells and nearly consistent among three groups , and as high as normal cells in combined treatment group . Conclusion The expression level of miR-196b in K562 cells could not return to normal treated with 5-Aza-2 ’-deoxycytidine or 4-phenylbutyric acid separately , while could restore normal when treated with both agents , indicating that miR-196b expression level in K562 cells is related with both DNA methylation and histone acetylation .

Objective To study the application of Cell Counting Kit-8(CCK-8) in detecting the growth inhibiting effect of 5-Aza-2’-deoxycytidine on chronic myeloid leukemia cell .Methods The proliferation of K562 cells was detected by CCK-8 with different concentrations of 5-Aza-2 ’-deoxycytidine and the cell cycle and apoptosis of K 562 cells were detected after K562 treated by 50% inhibitory concentration of 5-Aza-2 ’-deoxycytidine .Results The 50% inhibitory concentration of 5-Aza-2’-deoxycytidine was 15.55nmol/L, after treated with this concentration , K562 cells showed that G2 phase arrest occurred , proliferation inhibited and apoptosis peaks appeared .Conclusion Inhibition of proliferation of K562 cells with different concentrations of 5-Aza-2’-deoxycytidine varied in a dose-dependent relationship , and 5-Aza-2’-deoxycytidine could promote apoptosis of K 562 cells.CCK-8 can be used in detecting the effect of 5-Aza-2’-deoxycytidine on chronic myeloid leukemia cells .

OBJECTIVETo explore a new technique for repair of alveolar cleft by sutural distraction osteogenesis.

METHODSNine 8-weeks mongrel dogs were used in this study, three being in the control group, six in the experimental group. Alveolar cleft model was created surgically in all animals. Two weeks later, a U-shaped distractor made of Ni-Ti memory alloy wire was insterted into the premaxilla to distract the mid-premaxillary suture. When the premaxilla of the cleft side approached the ipsilateral maxilla, periosteoplasty of the alveolar cleft was performed. The distractor was removed at two weeks after periosteoplasty. The results were evaluated clinically, radiographically, morphologically and histologically.

RESULTSThe cleft model in dogs was stable and similar to the human alveolar cleft. In experimental dogs, the premaxilla was moved gradually toward the maxilla so that the cleft was closed. The distracted mid-premaxillary suture showed a gradually widened traingle, with its tip being posterior. The density of the distracted traingle suture was increased gradually. Bony repair was achieved completely at the cleft three months post-periosteoplasy. The morphology of the mid-premaxillary suture was restored.

CONCLUSIONThe alveolar cleft could be repaired by the technique of mid-premaxilla suture distraction.

To optimize indices of molecular identification for authentication of Ginseng Radix et Rhizoma and Panacis Quinquefolii Radix, four indices, including sequence similarity, specific positions, genetic distance and phylogenetic tree, were compared based on trnL-trnF sequences. Total DNA was extracted from Ginseng Radix et Rhizoma and Panacis Quinquefolii Radix, and trL-trnF sequences were amplified and sequenced. Sequence similarity was calculated by BLAST analysis. Specific positions were compared by DNAman software. Genetic distance and phylogenetic tree were analyzed by Mega software. The results showed that the inter-specific and intra-specific similarity of P. ginseng and P. quinquefolius respectively was 100% and 99. 6%. There were four specific positions at G153A, T463A, C732G and T818C. The inter-specific genetic distance (0) of trL-trnF sequences was lower than intra-specific genetic distance (0. 004). P. ginseng can be distinguished from P. quinquefolius based on the phylogenetic tree. It is concluded that Ginseng Radix et Rhizoma and Panacis Quinquefolii Radix can be authenticated by identification indices of sequence similarity, specific positions, genetic distance and phylogenetic tree. Index of specific positions based on trnL-trnF sequences is the most efficient index to authenticate Ginseng Radix et Rhizoma and Panacis Quinquefolii Radix.

OBJECTIVETo study pharmacokinetic effect of Aikeqing Granule (AG) by different medication ways on zidovudine (AZT) in highly active antiretroviral therapy ( HAART) of rats.

METHODSTotally 36 rats were administered with corresponding medications by gastrogavage, group I [HAART: AZT 31.5 mg/kg +3TC 31.5 mg/kg + Efavirenz (EFV) 63.0 mg/kg], group II (HAART+AG525 mg/kg), group III (HAART and AG 525 mg/kg after a 2-h interval). Drug concentrations of AZT were determined by high performance liquid chromatography-mass spectroscopy (HPLC-MS) before HAART, and at 0.5, 1, 2, 3, 4, 6, 8, 10, 12 h after HAART, respectively. Pharmacokinetic parameters [such as t1/2, Tmax, Cmax, AUCo-t, plasma clearance rate (CL)] were calculated by DAS2.0 Software.

RESULTSThe-equation of linear regression of AZT was good, with the precision, coefficient of recovery, and stability definitely confirmed. AUC in group II and III was larger than that of group I. There was no statistical difference in t1/2, Tmax, Cmax, AUC0-12 h, or AUC0-∞ among groups (P > 0.05).

CONCLUSIONAG combined HAART could enhance the Cmax of AZT.
