Objective To investigate the osteoclast′s function levels in infants and toddlers and the relationship between the osteoclast function and sex,age,body length,body weight and body mass index(BMI).Methods Sixty-eight children(37 boys and 31 girls,aged from 1 to 36 months) were studied.All of the children were in good health.These children were divided as infants group and toddlers group according to their age.Just before the samples were collected,the children′s body weight,body length were measured and the BMI were calculated.Two biochemical markers,such as serum tartrate-resistant acid phosphatase 5b(TRAP5b) and urine deoxypyridinoline(DPD) were measured.Results The difference of serum TRAP5b concentration between infants and toddlers was significant at the level of P

Objective To study the biofilm formation ability and related gene distribution of Staphylococcus (S .) aureus iso‐lated from urinary tract infections to provide the theoretical basis for the prevention and treatment of clinical infection .Methods The minimal inhibitory concentration was detected using the agar double dilution method .The bacterial adhesion ability was deter‐mined by flat colony counting method .The biofilm formation ability was analyzed by the 96‐well crystal violet staining method .The biofilm‐associated genes were detected by PCR amplification .Results Eleven clinical strains of S .aureus were high resistant to pen‐icillin and erythromycin ,whereas were all sensitive to vancomycin and nitrofurantoin .All the isolates had a strong ability of adhe‐sion ,but the biofilm formation ability was weak .Among them ,the icaAD and icaBC genes were amplified in 10 S .aureus isolates . Conclusion The adhesion ability and biofilm formation ability of S .aureus isolated from urinary tract infections have the strain differences ,and ica is an important gene of S .aureus biofilm formation .

Objective To investigate the correlation between α1-adrenergic receptor and the pathological behavior of cholangiocarcinoma, and the effects of norepinephrine (NE) on the proliferation of cholangiocarcinoma cell line QBC939. Methods Thirty-six samples of cholangiocarcinoma were resected in Southwest Hospital from August 2002 to March 2008. The expression of α1-adrenergic receptor in the 36 samples of cholangiocarcinoma tissue and 4 samples of normal bile duct tissue were detected by SABC technique. The proliferation of cholangio-carcinoma cell line QBC939 was detected after processing the cells with NE, phentolamine and prazosin. All the data were analyzed by chi-square test. Results The high positive expression rate of α1-adrenergic receptor was 68% (17/25) in patients with lymph node metastasis, which was significantly higher than 9% (1/11) in patients without lymph node metastasis (χ2=10.604, P<0.05). The high positive expression rate of α1-adrenergic receptor was 85% (11/13) in patients with middle and low positioned cholangiocarcinoma, which was significantly higher than 30% (7/23) in patients with hilar cholangiocarcinoma (χ2=9.753, P<0.05). NE promoted the proliferation of cholangiocarcinoma cell line QBC939 by stimulating the expression of α1-adrenergic receptor, and in a concentration-dependent manner. The proliferative effect was weakened as time passed by, and it was eliminated by phentolamine and prazosin. Conclusions The expression of α1-adrenergic receptor is diverse due to lymph node metastasis and the location of the tumor, α1-adrenergic receptor with high expression may play an important role in the proliferation and metastasis of cholangiocarcinoma.
7.Cases analysis and clinical classification of oligodontia.
Chinese Journal of Stomatology 2003;38(4):266-268
OBJECTIVETo classify the clinical symptoms of oligodontia and summarize the characteristics of the diseases.
METHODS33 patients with congenitally permanent teeth missing (6 or more than 6) were taken clinical examination, diagnosis, prosthetic treatment and made records of the status of tooth agenesis, systemic symptoms, and family history.
RESULTSThe symptoms of oligodontia were clinically classified into two groups: oligodontia with or without systemic syndromes. And the former has two typical kinds of diseases: anhidrotic/hypohidrotic ectodermal dysplasia (EDA) and Rieger syndrome.
CONCLUSIONSCorrect diagnosis and early treatment for these patients are of very importance.

OBJECTIVETo observe the effect of Ningdong Granule (NG) on serum levels of interleukin-12 (IL-12) and tumor necrosis factor-alpha (TNF-alpha) of children patients with Tourette's syndrome (TS).
METHODSTotally 90 TS children patients were randomly assigned to the NG group, the NG + Tiapride group (abbreviated as the combined treatment group), and the Tiapride group, 30 in each group. Besides,another 30 healthy children were recruited as the healthy control group. Patients in the NG group were treated with NG (consisting of all gastrodia rhizome, Codonopsis pilosula, Ophiopogon japonicus, white peony root, Rhinocerotidae, oyster, earthworm, licorice root, etc.), one dose daily, administered by dissolving it in boiled water, taken in two portions in the morning and in the evening respectively. Patients in the Tiapride group took Tiapride Tablet, 50 -100 mg each time, twice daily. The dosage was adjusted according to individual difference and changes of pathogenic conditions. The maximal dosage was 300 mg per day. Those in the combined treatment group were treated with equal dose of NG and Tiapride Tablet in combination. The treatment course was 3 months for all. Changes of pathogenic condition before and after treatment were assessed by Yale global tic severity scale (YGTSS). Serum levels of IL-12 and TNF-alpha were detected by enzyme-labeled immunosorbent assay (ELISA) before and after treatment.
RESULTS(1) The total effective rate of the NG group, the combined treatment group, and the Tiapride group was 79.3%, 83.3%, and 67.9%, respectively. It was the lowest in the Tiapride group (P < 0.05). It was significantly higher in the combined treatment group than in the NG group (P < 0.05). (2) The post-treatment YGTSS score was obviously lower in each group after treatment than before treatment (P < 0.05). The posttreatment YGTSS score was obviously lower in the NG group and the combined treatment group than in the Tiapride group (P < 0.05), but with no statistical difference between the fromer two groups (P > 0.05).(3) Compared with the healthy control group before treatment, serum levels of IL-12 and TNF-alpha (pg/mL) were 124.95 +/- 22.78 and 209.52 +/- 21.69 in the NG group, 126.14 +/- 25.65 and 208.97 +/- 22.46 in the combined treatment group, 123.00 +/- 24.26 and 205.10 +/- 26.16 in the Tiapride group, being higher than those in the healthy control group (64.56 +/- 27.59 and 78.13 +/- 33.42; P < 0.05). After treatment, serum levels of of IL-12 and TNF-alpha were 104.67 +/- 16.84 and 183.01 +/- 24.95 in the NG group, 109.04 +/- 16.81 and 179.87 +/- 23.45 in the combined treatment group, significantly lower than before treatment (P < 0.05). But there was no statistical difference in serum levels of IL-12 or TNF-alpha in the Tiapride group between before treatment (123.00 +/- 24.26 and 205.10 +/- 26.16) and after treatment (117.75 +/- 16.79 and 199.76 +/- 33.21; P > 0.05).
CONCLUSIONNG could modulate abnormal serum levels of IL-12 and TNF-alpha in TS children patients, which might be one of its pharmacodynamic mechanisms for treating TS.

Objective To identify the polyreactivity of a monoclonal natural anti-keratin autoantibody 3B4 and to analyze its possible molecular me chanism.Methods enzyme-linked immunosorbent assay (ELISA)and immunohistoche mistry were applied to test the binding reactivity of 3B4 against different anti gens and tissues.The variable region genes and their amino acid composition wer e sequenced.Results 3B4 could reacted with a range of antigens and tissues,i n addition to keratin and skin.The variable region genes of its light chain and heavy chain showed high homology with germline genes VK1 am4 and VH1 J558.42.H CDR3 region,which mainly composed of short side chain amino acids(from 294 to 324 nucleotides around the heavy chain),was the only motif that differs from ot her highly homologous immunoglobulin genes.Conclusions The monoclonal natural anti-keratin autoantibody 3B4,with its variable region genes highly homologo us to germline genes,is highly polyreactive.The flexibility of HCDR3 may contr ibute to the polyreactivity.
