Objective To investigate the effects of azithromycin on hyperoxia induced lung injury in neonatal rats.Methods Ninety 2-day-old neonatal rats were randomly divided into 3 groups (30 cases in each group):air control group,hyperoxia model group,azithromycin treated group.The rats in air control group were exposed to indoor air,and the rats in hyperoxia model group and azithromycin group were exposed to 900 mL?L-1 O2 for 14 days.From 2-days-after birth,rats in treated group received intraperitoneal injection of azithromycin (200 mg?kg-1)per day,rats in air control group and hyperoxia model group received intraperitoneal injection of normal saline.Ten rats in each group were executed and their lung tissues were taken out and were observed under a optical microscope on the 3rd,7th,14th days from the start.The expression of interferon gamma(IFN-?),connective tissue growth factor(CTGF) and matrix metalloproteinase-9 (MMP-9) in the lung tissues were detected by immunohistochemistry.Results There was no expression of IFN-? positive cells in air control group,but the expressional intensity level was gradually enhanced as the time of inhaling hyperoxia prolonged in hyperoxia model group,it reached the peak on the 7th day,and then obviously declined on the 14th day,but still higher than that of air control group.The expressional intensity level of IFN-? in azithromycin treated group was lower than that of hyperoxia model group in each time segment,there were significant differences among them(Pa

Objective To discuss the valuable influence of the total-body massage on the facilitation of the rehabilitation for the women in puerperium.Methods Both Chinese traditional medical total-body massage and the biological information theories and its methodology were employed in dealing with 50 cases of puerperants without contraindications,who had labored naturally 12 hours before and who had received cesarean sections 48 hours before. The results were compared with the control group in which conventional preventive health care for puerperants was adopted.Results Notable differences exist in the aspect of lochia,defecation,lactation and emotions between the two groups.Conclusion Significant benefits can be obtained from the massage to facilitate the rehabilitation of the women in puerperium while promoting their quality of lives and broadening the coverage of services of the preventive health care for the puerperants.

ObjectiveTo observe effect of head and body acupuncture and moxibustion on stroke.Methods183 stroke patients were randomly divided into 3 groups, head acupuncture and moxibustion, body acupuncture and moxibustion, and head body acupuncture and moxibustion. After two months treatment, effects of 3 groups were evaluated.ResultsThere were no differences between head group and body group, body group and head body group, but there was significantly difference between head body group and head group (P<0.05).ConclusionThe head body acupuncture and moxibustion can gain the best clinical effect on stroke patients compared with simply head or body acupuncture and moxibustion.

To investigate such physical indexes as hygroscopicity, angle of repose, bulk density, fillibility of compression of mixed powder of directly compressed auxiliary materials and fermented cordyceps powder by using micromeritic study methods. The results showed that spray-dried lactose Flowlac100 and microcrystalline cellulose Avicel PH102 had better effect in liquidity and compressibility on fermented cordyceps powder than pregelatinized starch. The study on the impact of directly compressed auxiliary materials on the powder property of fermented cordyceps powder had guiding significant to the research of fermented cordyceps powder tablets, and could provide basis for the development of fermented cordyceps powder tablets.

Objective To study exogenous expression and subcellular localization of wild type (WT ) and mu-tant PAX3 proteins in vitro by generating their expression plasmids for further study of pathogenesis of Waarden-burg syndrome (WS) .Methods The plasmids pECE-PAX3 and pcDNA3 .0-HA were ligased after they were cut by double enzyme digestion using molecular cloning technique to generate recombinant eukaryotic expression plasmid pcDNA3 .0-PAX3-HA ,which was as a template to generate expression plasmids pcDNA 3 .0 -H80D -HA and pcDNA3 .0-H186fs-HA of novel mutations H80D and H186fs of PAX3 gene .All constructs were verified by di-rect nucleotide sequencing .NIH3T3 cells were transfected transiently with the expression plasmids of PAX3 ,H80D and H186fs respectively .The exogenous expression of WT PAX3 protein and mutant H80D ,H186fs proteins were analysed using Western blot assay ,while their subcellular distribution were observed using immunofluorescence as-say .Results The DNA sequences of expression plasmids of PAX3 and its mutant H80D ,H186fs were correct . Both WT and mutant PAX3 proteins were detected at the expected size .WT PAX3 and H80D proteins were only lo-calized in the nucleus ,whereas H186fs protein showed aberrant localization in both cytoplasm and nucleus .Conclu-sion We successfully generated the recombinant eukaryotic expression plasmids of PAX 3 gene and its mutants and drew preliminary conlusion of gene mutation having effect on subcellular distribution of WT PAX 3 proteins in vitro , which lays experimental basis for further study of the moceluar mechanism of WS caused by PAX3 gene mutations in China .

OBJECTIVETo investigate the preventive effectiveness in reducing tooth decay and decalcification of different concentration of fluoride toothpaste for orthodontic patients.

METHODS86 patients were divided into the first test group and the second test group. The patients of the first test group brushed tooth with 1.1% sodium fluoride and acidulated phosphate gel. The patients of the second test group brushed tooth with 0.243% sodium fluoride in a silica base. The extent of facial tooth decay and decalcification of the twelve upper and lower teeth from right cuspid to left cuspid was scored blindly and independently by four observers after 12 months of product use. The scores were rated either one (having tooth cavity/decalcification) or zero (no tooth cavity/decalcification). Four observer's readings were averaged per tooth, and then per patient for the two treatment groups.

RESULTSAfter 12 months of product use, the mean caries score of the first test group was 0.326, and the mean caries score of the second test group was 0.490. There was significant difference between them.

CONCLUSIONA gel system containing 1.1% sodium fluoride and acidulated phosphate provides a clinically better efficacy in reducing tooth decay and decalcification than does a toothpaste containing 0.243% sodium fluoride in a silica base under and adjacent to orthodontic brackets used in orthodontic therapy.
