Background Graves ophthalmopathy is generally considered to be an organ-speeifie autoimmune disease.It was reported that 99Tc-methylenediphosphonate (99Tc-M)P) has therapeutic effect on Graves ophthalmopathy,though the mechanism has not been completely delineated.Objective This study was to explore the effects of 99Tc-MDP on the proliferation of retrooeular fihrohlasts (RFs) hyaluronic acid (HA) synthesis,and the expression rate of human leucocyte antigen-DR (HLA-DR) and intercellular adhesion molecule-1 (ICAM-1) in cultured RFs.Methods Retroocular connective tissue was obtained from 2 eyes with Graves ophthalmopathy during the orbital decompression surgery.RFs were cultured with explant culture method in DMEM medium with 20％fetal bovine serum.The cells of 2-7 generations were used in the study.Interferon γ (IEN-γ),interleukin-1 (IL-1),tumor necrosis factor-α (TNF-α) was added in medium for 72 hours to stimulate the growth of the RFs,and then 10,100 and 1000 mg/L 99Tc-MDP was respectively used to co-culture the cells with IFN-γ,IL-1 or TNF-α.3H-TdR incorporation was used to detect the proliferation of RFs,and synthesis of HA,expression rate of HLA-DR and ICAM-1 in RFs were assayed by radio-immunoassay and flow cytometry,respeetively.Results Cultured cells showed the fibrous shape under the inverted microseope with the positive response for vimentin and absent response for cytokeratine.After addition of TNF-α,IFN-γ and IL-1,the proliferation value of RFs,HA level,the expression rate of HLA-DR and ICMA-1 in RFs was (4918.33±297.91) counts/min,(505.83±41.29)mg/L,(56.88±14.67)％ and (63.57± 14.11)％ respectively,showing significant differenee in comparison with normal control group(P＜0.01).However,after co-culture of ＞100 mg/L 99Tc-MDP with TNF-α,IFN-γ and IL-1,the proliferation value of RFs,HA level,the expressing rates of HLA-DR and ICMA-1 were significantly lower than those in the TNF-α,IFN-γ and IL-1 only culture groups(P＜0.01),but were still higher than those in the normal group.Conclusions 99Tc-MDP can suppress cytonike-induced activation and growth of RFs derived from Graves ophthalmopathy in vitro at a dosedependent manner.

Objective To analyze the clinical features of immunoglobulin A(IgA) nephropathy(IgAN) occurring in the context of pre-vious acute glomerulonephritis.Methods The clinicopathologic features of 108 cases(77 males,31 females,aged 3.2 to 14.0 years old) of IgAN were analyzed restrospectively with the onset of acute glomerulonephritis in this department from Jan.1994 to Dec.2005.Results Of 108 cases with IgAN,10 cases were with the onset of acute glomerulonephritis. All the 10 cases presented with edema, hematuria and proteinuria.Eight cases had macroscopic hematuria, lasting for 2 days to 2 months.Four cases had recurrent macroscopic hematuria,microscopic hematuria lasting for 16 months.Urine protein qualitative +-+++ lasted for 1-8 months.Two cases had hypertension;2 cases had increasing blood uria nitrogen and serum creatinine.The increase of anti-streptolysin O(ASO) titer was detected in 5 of 9 cases.Two cases had a high titer of DNase-B antibody, and 4 cases had hypocomplementemia.Eight cases had prodromal infection with an interval time varying from 1 to 5 days.Renal biopsies revealed mesangial proliferative glomerulonephritis in 9 cases and focal segmental glomerulosclerosis in 1 case, all with mesan-gial IgA deposition.Conclusions The interval time between the prodromal infection and nephritis symptoms is mostly short in IgAN with the onset of acute glomerulonephritis, while macroscopic and microscopic hematuria remain a fairly long time or recurrently aggravate. Renal biopsy is necessary to diagnose IgAN for this kind of children.

The middle cerebral artery occlusion(MCAO) in rats remained a focus cerebral ischemic model that is non-incisioned,reliable,as well as the ischemic and refusion time can be controlled,which is widely used since it was created.However,because it is needed complex operations,associatied with many factors,it is difficult to establish.Many scholars have modified the operation,shape of the occlusion line,as well as the variety,narcotic drugs and so on.

It is generally accepted that locomotion in mammals, including humans, is based on the activity of neuronal circuits within the spinal cord (the central pattern generator, CPG). Recent studies indicate a plastic behavior of the spinal neuronal circuits following a spinal cord injuries (SCI). Studies have shown that body weight support treadmill training (BWSTT) is effective in restoring locomotor function in cats with a complete spinal lesion. It has become possible to regain some locomotor activity in patients with spinal cord injury through an intense training on BWSTT, as in cat. So, it is a staired problem how to take advantage of the plasticity of spinal locomotor pattern generator and design the gait training program for SCI patients.

Ginseng is a typical adaptogen which has resistance to various stresses. This effect is related to the hypothalamic-pituitary-adrenal (HPA) axis. As the main active ingredients, saponin has the similar structure to steroids. The regulation characteristics of ginseng saponin on the HPA axis are narrated from the aspects of total saponin and saponin monomers in this paper after the introduction of adaptation definition and HPA axis regulation mechanisms. Pharmacological effects of ginseng saponin and the regulation effect of HPA axis are summarized finally.

Objective To observe the change of umbilical artery S/D value in the third trimester pregnant women with overt hypothyroidism(OH) or subclinical hypothyroidism(SCH).Methods We collect the data of 37-42 weeks pregnancy from January 2014 to December 2015.We devided them into OH group,SCH group and contral group.We compared the umbilical artery S/D value in these three groups and analyzed the relativity between S/D value and thyroid hormone.Results The S/D value was 2.46 ± 0.31 in OH group,2.48 ± 0.27 in SCH group and 2.32 ± 0.17 in control group.The differences were statistically significant between OH group and contral group (P =0.000),SCH group and contral group (P =0.000).There was no statistically significant between OH group and SCH group (P =0.907).The proportion of cases number during different S/D value range in these three groups had difference (P =0.000).The S/D value was positively correlated to TSH in OH group (r =0.186,P =0.037) and SCH group (r =0.146,P =0.015).There was no correlation between FT3 and S/D value(P ＞ 0.05) or FT4 and S/D value(P ＞ 0.05) in both OH and SCH group.There was no correlation between thyroid hormone and S/D value in the contral group either.Conclusion Both OH and SCH can effect umbilical artery S/D value in the third trimester pregnancy.
