Using colon adenocarcinoma cell line HT-29 as testing material, adhesion test was carried out for 24 strains of Bifidobacteria isolated from dejecta of longevous people aged one hundred years. The results showed that all strains could adhere to colon adenocarcinoma cells HT-29, among which the strains of TTF, Z2, TZ5 and (J-1) showed higher adhesive capability. Thus these four strains of Bifidobacteria were further tested for their endurance to stomach acid and bile acid. The production of vitamin B by these bacterial were also tested. All these tests indicated that the strain of TTF has high ability to produce Vitamin B_(1), B_(2), B_(6), B_(12), The survival rate after the treatment under pH 3.0 for 120 min was 93.11%, at the same time, the strain TTF can survive after being treated with 2% bile acid for 24h.

To study the stimulation effect to the growth of Bifidobac te rium sp. A04, 4 kinds of oligosaccharide, 8 kinds of Chinese traditional medi cine and 4 kinds of food raw materials were used. The results indicates that so ya bean oligosaccharide is the most effective (P

Objective To investigate the prevalence of endemic fluorosis in Guide county of Qinghai province, in order to provide appropriate measures to monitor and control the disease. Methods Damo, Wenquan, Baoning villages(water source has been changed) and Taiping village(water source has not been changed) in Guide county were involved in the study in 2008. One tap water sample was collected in dry and rainy seasons, respectively. Water fluoride was tested in accordance with the "Standard Test Methods for Drinking Water" (GB/T 5750.5-2006); of all the children aged 8 to 12, dental fluorosis was diagnosed using Dean criteria; 6 copies of urine samples were collected in each age group, urinary fluoride was measured using fluoride ion-selective electrode (WS/T 89-1996). According to the "Clinical Diagnostic Criteria of Endemic Skeletal Fluorosis "(WS 192-2008), clinical skeletal fluorosis was determined in adults over the age of 16 by X-ray examination for 10 people in each selected village. Results The mean water fluoride was 0.58,0.38,2.28,0.37 mg/L in Damo, Wenquan, Taiping, and Baoning villages, respectively, and that of Taiping village exceeded the national standard(1.0 mg/L). One hundred and ninety-three children aged 8-12 were checked, the detection rate of dental fluorosis was 49.74% (96/193); urine samples of 116 children were tested, median urinary fluoride was 1.49 mg/L A total of 1503 adults over the age of 16 were examined, the clinical detection of skeletal fluorosis was 51.63%(776/1503); a total of 82 people were X-rayed, X-ray detection of skeletal fluorosis was 20.73%(17/82). The characteristic of X-rays were degeneration and ossification of interosseous membrane. Conclusions Prevalence of dental fluorosis of children and adult clinical skeletal fluorosis are higher. The endemic fluorosis is still comparatively serious. Prevention efforts need to be further strengthened.

The clinical value of whole body positron emission tomography/computed tomography (PET/CT) as an imaging tool in diagnosis of ophthalmic tumors was investigated.The retrospective observational case series were performed on the patients with suspected ophthalmic tumors who underwent whole body PET/CT.The golden standard of diagnosis was the final pathological diagnosis or the results of long-term follow-up for patients without surgery/ biopsy.PET/CT findings were compared with the golden standard.The sensitivity,specificity,accuracy and positive likelihood ratio of PET/CT in the detection of ophthalmic tumors were calculated.The clinical application of PET/CT in different types of ophthalmic tumors was evaluated.The results showed that 30 patients (18 males and 12 females) with a mean age of 43.0 years (range 4-63 years) were collected.The mean sizes of orbital tumors and intraocular tumors were 26.8 mm×17.8 mm and 11.2 mm×6.1 mm,respectively.The overall sensitivity,specificity,accuracy and positive likelihood ratio of whole body PET/CT in ophthalmic tumors were 76.5％,71.4％,75.0％ and 2.67,and were 62.5％,100％ and 70.0％ in intraocular tumors,and those were 100％,60.0％ and 84.6％ in orbital tumors,respectively.PET/CT findings were applied to help make appropriate treatment options in 27 out of 30 patients (90.0％),and 12 (40.0％) patients changed the treatment strategy.False negative results in 4 cases and false positive results in 2 cases were observed in this series.It was suggested that PET/CT was an effective imaging modality in detecting,diagnosing and developing therapeutic schedule for patients with ophthalmic tumors.It was more sensitive and accurate for detecting orbital tumors than for detecting intraocular tumors.

Erchen Decoction is widely used to dampness-phlegm syndrome and it can be flexibly used in clinical application by my supervisor Professor OU Zheng-wu, especially in cough, pneumonia, asthma and influenza, which has obvious efficacy in treatment. This article reviewed five medical cases during the follow-up process with Professor OU in application of Erchen Decoction, with a purpose to share experience of famous doctors and improve TCM diagnosis and treatment level together.

? AIM: To investigate health - related quality of life ( HRQOL ) state in children with intermittent exotropia using the Intermittent Exotropia Questionnaire ( IXTQ ) and research the effect of strabismus surgeries on HRQOL.?METHODS: In this prospective study, we chose 42 patients with intermittent exotropia ( aged 5-17 years) as case group, and 42 patients ( aged 5-17 years) as control group. The Chinese IXTQ was used to evaluate HRQOL at 1d preoperatively and 3mo postoperatively in the two groups, and the differences of the two groups before and after surgery and the effect of strabismus surgery on HRQOL were analyzed.?RESULTS:The scores of HRQOL in control group were statistically significant higher than that of case group ( P<0. 01 ). Every items showed a statistically significant difference except on “Kids tease me because of my eyes”and “ My eyes make it hard for me to make friends” ( P<0.05). At 3mo postoperatively ,the scores of HRQOL in case group significantly increased than that at 1d preoperatively(P<0. 01). Child IXTQ of case group was lower on every items than those of control group after surgery(P<0. 05).?CONCLUSION:Intermittent exotropia could affect the HRQOL in psychosocial and visual functional. The greatest HRQOL concerns for children with intermittent exotropia were shutting one eye when sunny, waiting for their eyes to clear up instead of taunts and friendship. The surgical treatment could improve HRQOL in children with intermittent exotropia.

OBJECTIVETo find the development rules of microbial community in rhizoma sphere of the cultivated Atractylodes lancea.

METHODTotal bacteria, fungi and actinomyces were counted by CFU x g(-1) though dilution plate method. And genomic DNA of microbes were extracted and amplified by primers of E. coli's 27f and 1492r to get the 16S rDNA, then the restriction endonuclease Hinf was used to digest the 16S rDNA.

RESULTTotal bacteria, fungi and actinomyces in 2-year old soil were lower than in 1-year old soil, they decreased 46. 14%, 49. 25%, 31.88% respectively and made the ratio of themselves changed. At the same time, all the 8 soil samples got fine 16S rDNA bands, which were about 1500 bp. And the main bands of most of the samples were found at 1000 bp, but the weak bands of each were different although most bands in the same year samples were more similar than in different year ones.

CONCLUSIONIt is indicated that the change of soil microbial community may has some relation to the continous cropping barrier of A. lancea.
