Objective To investigate the correlation between angiotensin converting enzyme(ACE) gene polymorphism and kawasaki disease(KD).Methods A 287 bp Alu fragment in intron 16 of the ACE gene was used as insertion(I)/deletion(D) polymorphism marker. The ACE genotype of 28 children (10 children complicated coronary dilataltion) with KD and 35 healthy controls were detected by polymerase chain reaction (PCR), and ACE concentration in blood serum was measured by ultraviolet-spectrophotometer assay.Results 1.The ACE concentration was significantly higher in KD group than that in healthy control group(P

To compare the efficacy of interferon and thymosin alpha-1 combination therapy with interferon monotherapy for HBeAg positive chronic hepatitis B. The relevant randomized controlled trials were searched throughout PubMed, EBSCO, Cochrane Library, CBMdisc, VIP, WanFang since Janurary 1990. Studies were included if patients were followed up for at least 6 months after cessation of treatment. Meta-analysis was carried out with RevMan5.0 software. Subgroup analyses were used at different time of observation. Seven randomized controlled trials were included(535 patients in total). According to the results of meta-analysis, the combination therapy was remarkably more effective than monotherapy both at the end of the treatment and the follow-up in terms of HBV-DNA negative rate (54.9% vs 36.3%, OR=2.39, 95% CI=1.64-3.49, P value is less than 0.01; 58.6% vs 30.7%, OR=3.68, 95% CI=2.51-5.41, P value is less than 0.01, respectively), ALT normalization rate (74.5% vs 60.9%, OR=1.94, 95% CI=1.26-3.00, P value is less than 0.01; 74.0% vs 55.6%, OR=2.36, 95% CI=1.54-3.62, P value is less than 0.01, respectively), HBeAg loss rate (56.9% vs 36.7%, OR=2.38, 95% CI=1.61-3.51, P value is less than 0.01; 62.2% vs 33.2%, OR=3.42, 95% CI=2.31-5.06, P value is less than 0.01, respectively) , and HBeAg seroconversion rate (40.1% vs 29.0%, OR=1.65, 95% CI=1.10-2.47, P value is less than 0.05; 47.0% vs 29.5%, OR=2.13, 95% CI=1.43-3.16, P value is less than 0.01, respectively); the HBsAg loss rate of the combination therapy group was significantly higher than that of the monotherapy group only at the end of the follow-up (9.8% vs 3.7%, OR=2.92, 95% CI=1.09-7.76, P value is less than 0.05). Interferon and thymosin alpha-1 combination therapy achieves superior effect with no increase in the adverse effects as compared to interferon monotherapy for HBeAg positive chronic hepatitis B.

Objectives To study the level and development of serum specific antibody against severe acute respiratory syndrome coronavirus(SARS-CoV)of different populations in SARS pestilence district after SARS outbreak in a general hospital.Discuss SARS sub-clinical infection and protective action of the IgG antibody.Methods Seroepidemiology method,enzyme-linked immunosorbent assay (ELISA)and indirect immunfluorescence assay(IFA)were employed to investigate the changing level of serum antibody to SARS-associated coronavirus in non-SARS population in SARS pestilence district during and after SARS outbreak.The development of IgM and IgG antibody in patients with SARS in 6 weeks after the onset of SARS was studied qualitatively.The level changing of IgG antibody in con- valescent patients with SARS in 82 weeks after the onset was observed dynamically.Results The ELISA test outcome of IgG antibody was negative in 200 non-SARS people who were random samples of normal mass in SARS pestilence district and common community.The positive rate was 0.41% in 487 SARS high risk population tested by ELISA,but showed negative when retested by IFA.The A value level of IgG antibody existed significant difference in non SARS mass during and after SARS outbreak and the later's was higher them the former's(P

The clinical and mechanism studies of acupuncture and moxibustion in treatment of dementia from modern literature in recent 15 years are reviewed. In clinical studies, changes of scores for relative dementia scale and daily life scale, relative laboratory indexes, imaging indexes and physical diagnostic indexes after acupuncture are explored. In studies of mechanisms, dementia models are established with different methods and changes of various indexes were observed. Studies find that acupuncture and moxibustion can improve intelligence and social activity ability, increase therapeutic effect and have good effects on important indexes of dementia. However, the criteria for diagnosis, therapeutic effects, syndrome standardization, evaluation of long-term therapeutic effects and prognosis for dementia still need to be further studied.

OBJECTIVETo assess the dental caries prevalence of children in Yinchuan.

METHODSThe 3-, 5-, 12-, 15-year-old children were chosed from nursery, primary and middle schools of Yinchuan in 1990, 1996 and 2001. The survey was carried out by five senior dentists from stomatologic hospital of Yinchuan according WHO criteria. DMFT, DMFS and the ratio of tooth filled were counted.

RESULTSFrom 1990 to 2001, the prevalence of dental caries of 3-, 5-, 12-year-old children was degression (P < 0.01). But the prevalence of dental caries of 15-year-old children had no obvious change. The dental caries of small proportion of children were serious. The ratio of tooth filling was low.

CONCLUSIONWith the development of oral health education, the prevalence of dental caries of 3-, 5-, 12-year-old children in Yinchuan is descend. But the diagnosis, prevention and treatment should be strengthened, and the ratio of tooth filling should be increased.

OBJECTIVETo study the possible relationship between serum ferritin levels and susceptibility to attention deficit hyperactivity disorder (ADHD) in children.

METHODSThe papers relating to the relationship between serum ferritin levels and susceptibility to childhood ADHD were searched in the Database CBM, CNKI, VIP and PubMed. The Meta-analysis software RevMan 5.0 was used for the heterogeneity test and for the pooled OR calculation. Sensitivity and publication bias analysis were performed.

RESULTSFive control studies were included for the Meta analysis, including 258 cases of ADHD and 138 control cases. There was heterogeneity in the studies on the relationship between serum ferritin levels and susceptibility to childhood ADHD (P=0.003). So the studies were analyzed using the random-effect model. The pooled OR of serum ferritin levels and susceptibility to childhood ADHD was -23.09 (95%CI:-33.06-13.13; P<0.00001). The funnel plots did not indicate the existence of publication bias.

CONCLUSIONSThe results from present Meta analysis can prove that serum ferritin levels are associated with susceptibility to childhood ADHD.

OBJECTIVETo compare therapeutic effects between suspine rotation and flexion manipulation for treating lumbar disc herniation.

METHODSFrom December 2008 to January 2011, 134 patients with lumbar disc herniation were treated, including 74 males and 60 females,ranging in age from 17 to 67 years,33 patients with age over 50 years old. According to diagnosis the ladder of the 9 cases bulging type, 74 hernia type, 51 cases free type. The patients were randomly divided into treatment group ( 69 cases) and control group (65 cases). All the patients were treated with the three-dimensional computer-controlled traction therapeutic apparatus,with continued traction for 20 minutes. After traction, flexion manipulation and rotat-ing manipulation were respectively adopted in treatment group and control group (on alternate days one time, 3 times as a course of treatment). The symptoms and signs (including back pain and discomfort, lower limb pain and numbness, powerless urination and defecation,numbness in perineum, straight-leg raising degree,ability of lower extremity walking,work and live) of patients were observed after treatment.

RESULTSAll patients were followed up for 0.5 to 6 months with an average of 1.1 months. After treatment, the symptoms and signs of patients have significantly improved (P < 0.01), but the symptomes of powerless urination and defecation,numbness in perineum was not improved obviously (P>0.05). Forty-two of 69 patients in treatment group got excellent result, moderate in 20, poor in 7; Twenty of 65 patients in control group got excellent result, moderate in 25,poor in 20.

CONCLUSIONThe whole effect of lumbar backwards rotation manipulation is more satisfactory than flexsion manipulation for treating lumbar intervertebral disc herniation. But spinning force and times should be noticed.
