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

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.

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 observe the short-term efficacy and radiotherapy induced acute reactions of sarcandra glabra (SG) combined chemoradiotherapy for treating patients with local advanced nasopharyngeal carcinoma.

METHODSTotally 100 nasopharyngeal carcinoma phase III - IVa patients were randomly assigned to the control group and the observation group, 50 patients in each group. All patients received chemoradiotherapy. Patients in the observation group took SG decoction at the daily dose of 20 g.

RESULTSTotally 98 patients completed the treatment. There was no statistical difference in the complete remission rate, the partial remission rate, 1-year and 2-year total survival rates, or disease free progression rate between the two groups. The occurrence rate of II - III degree radioactive oral mucositis and dry mouth were obviously lower in the observation group than in the control group, showing statistical difference (P <0.05).

CONCLUSIONSG combined chemoradiotherapy could attenuate radiotherapy induced acute adverse reactions in treating advanced nasopharyngeal carcinoma.

To study the application characteristics of copovidone (PVP-S630) in Xinyueshu extracts during the spray drying process, and its effect on such pharmaceutical properties as micromeritics and drug release behavior. PVP-S630 was added into Xinyueshu extracts to study on the spray drying, the effect of different dosages of PVP-S630 against the wall sticking effect of the spray drying, as well as the power property of Xinyueshu spray drying power and the dissolution in vitro behavior of the effective component of hyperoside. The results showed that PVP-S630 revealed a significant anti-wall sticking effect, with no notable change in the grain size of the spray drying power, increase in the fluidity, improvement in the moisture absorption and remarkable rise in the dissolution in vitro behavior of hyperoside. It was worth further studying the application of PVP-S630 in spray drying power of traditional Chinese medicine.
