Objective To understand the iodine deficiency disorders in Xunhua county Qinghai province, and to provide reference values for setting up prevention and control strategy. Methods According to historical data of Xunhua county, 1 township center elementary school and 1 village elementary school were sampled in Qingshui, Baizhuang, Hongqi, Jiezi and Galeng townships. A total of 9 elementary schools were investigated (Caleng has only 1 elementary school). Fourty children aged 8-10 years were checked thyroid size by palpation in every school. Twenty children were chosen to assay their urinary iodine and edible salt iodine in every school. Thirty 5-grade students were surveyed by questionnaire on health education in every school. Ten housewives were inquired prevention knowledge on iodine deficiency disorders and salt iodine level was tested in every village. Results Goiter rate was 7.9%(30/378) in children aged 8-10 years, with Baizhuang and Galeng the highest (11.9%,5/42), and Qingshui the lowest (2.4%, 1/42). The median was 196.5 μg/L in children aged 8-10 years, and urinary iodine level lower than 50 μg/L was accounted for 5.3% (11/208), but that value was 25.0% (5/20)in Galeng. The average qualified rate of using edible salt was 91.4%(159/174), and that rates were 79.0%(15/19), 83.3%(15/18) and 89.5%(17/19) in Chajia, Tuanjie and Minzhu villages, respectively. The average score were 2.8, 2.1 in health education survey of the 5-grade students and housewives. Conclusions After years effort in prevention and control of iodine deficiency disorders, remarkable progress has been made in Xunhua County. The monitoring of iodized salt and the knowledge spreading are still need to be strengthened.

The diversity in Tibetan kefir grains and dynamics of the microbial community during the fermentation of Tibetan kefir by PCR-DGGE fingerprinting technique were studied.The results showed that bacterial community of Tibetan kefir grains was more complex than that of yeast.The bacteria communities between different Tibetan kefir grains showed 78%~84% similarity, and yeast 80%~92%.Bands B, E and N of DGGE profiles of the microbial community during fermentation of Tibetan kefir were present throughout the fermentation.Analysis of sequence date showed the majority of the DGGE bands of bacteria community corresponded to LAB, and the most intense band (band E) was completely homology to Lactococcus lactis.

Objective:To find out whether it is accurate to estimate femoral version based on femoral broach after femoral neck osteotomy using computed tomography scans.Methods:In 32 total hip arthro-plasty (THA),we performed CT scans before and after operation.Four possible levels (lesser trochan-ter,5 mm above,10 mm above and 15 mm above the lesser trochanter)of broach version were calculated based on the pre-operative CT scan.Stem versions were measured on the post-operative CT scan.We de-termined the difference between the preoperative broach version and the postoperative stem version using the Student’s t-test for paired samples assuming equal variance.Results:For the operated hips,pre-operative hip version differed according to the level of measurement.Our findings showed that the average femoral version was 37.0°±11.0°at the level of the lesser trochanter (section 1),34.3°±10.6°at 5 mm above the lesser trochanter (section 2),28.1°±10.9°at 10 mm above the lesser trochanter (sec-tion 3),and 22.4°±13.7°at 15 mm above the lesser trochanter (section 4),and that the average ver-sion for the femoral neck (FNV)was 12.9°±13.8°.The postoperative hip version was the stem version (FSV),which we found to be an average of 26.1°±11.0°.The mean femoral version for section 1 and 2 was larger than the mean postoperative stem version (P<0.01);the mean version for sections 3 and 4 did not differ from the mean postoperative stem version (P>0.05).The mean femoral neck version was less than the mean postoperative stem version (P<0.01);the difference was 13.2°±11.1°of the in-creased anteversion on average for the FSV compared with FNV.Conclusion:The accuracy of estimated femoral version after arthroplasty depends on broach level.When it is 10 mm above the lesser trochanter, stem version estimation is accurate,but below that level,there is a tendency to overestimate.

Objective To observe effect of arginine on wound healing of diabetic rats.Meth- ods Forty male Lewis rats were equally and randomly divided into diabetic group and normal control group.The diabetic group were rendered with diabetic by using intraperitoneal(IP)streptozotocin seven days prior to surgery and underwent a dorsal skin incision with implantation of polyvinyl-alcohol sponges. Either of two groups were subdivided into arginine treatment group and saline treatment group,10 rats in each group,of which the arginine treatment group received arginine at 1 g/kg per day by IP injection, while the saline treatment group received saline injection only.Animals were sacrificed 10 days post wound to observe antibreakage tension,hydroxyproline content and mRNA expression of procollagenⅠandⅢ.Results Diabetic wounds had greatly decreased breaking strengths compared with controls. Arginine significantly enhanced wound breaking strengths,increased wound hydroxyproline levels and ele- vated mRNA for procollagenⅠandⅢin both diabetic and control animals as compared to their saline-trea- ted counterparts.Conclusion Arginine can effectively promote healing of diabetic wounds in rats.

This study is to investigate the effect of osthol on osteoclasts' activity, bone resorption as well as apoptosis in vitro, and explore the mechanism of osthol in preventing osteoporosis. Osteoclasts were separated from long-limb bones of new born rabbits, cultured in 24-well plate with glass slices and bone slices, and treated by 1 x 10(-5) mol x L(-1) osthol. Osteoclasts were identified by observing live cells with phase contrast microscope, HE staining, TRAP staining and toluidine blue staining of bone resorption pits. The numbers of bone resorption pits were counted as well as the surface area of bone resorption on bone slice. Osteoclasts were stained with acridine orange to detect the cell apoptosis. The ratio of apoptotic osteoclasts was observed under fluorescence microscope. The gene expression of RANKL, OPG, TRAP and p-JNK1/2 protein expression were examined using real time PCR and Western blotting, respectively. Comparing with the control group without osthol, the rates of apoptotic osteoclasts increased obviously and the number and area of bone resorption pits decreased evidently with 1 x 10(-5) mol x L(-1) osthol. There is significant difference between control group and experiment group treated by 1 x 10(-5) mol x L(-1) osthol. Therefore, the osthol through RANK+RANKL/TRAF6/Mkk/JNK signal pathway inhibits the osteoclasts activity, enhances osteoclasts apoptotic and inhibits the bone resorption.

The characteristic fingerprint of conventional dairy Nanhanshuishi was established by X-ray diffraction (XRD), based on similarity of caculation on public peaks by MATLAB software, and the feasibility of new dairy technology of microwave method was explored between XRD and the dissolution rate in artificial simulation gastric juices. The result showed that similarity of shared peak in XRD of conventional dairy Nanhanshuishi was > 95%, This XRD characteristic fingerprint of conventional dairy Nanhanshuishi had strong specificity, could be used to provide a reference for identification and quality evaluation. This study also showed that the similarity of microware dairy products and conventional dairy products was good, and the sample of microwave 15 min was the best, and new dairy method by the microwave could replace the traditional method.

Objective To investigate the effects of puerarin on the expression of human umbilical vein endothelial cells (HUVECs) tissue factor (TF) and tissue factor pathway inhibitor (TFPI) induced by oxidized low-density lipoprotein (ox-LDL).Methods After HUVECs were incubated with different concentrations of puerarin and 50 mg/L ox-LDL,the expression of TF and TFPI mRNA and protein were detected by real-time fluorescent quantitative PCR and Western blot respectively.Results Compared with control,treatment with ox-LDL caused the augment of TF mRNA and protein expression (P<0.01),and the decrease of TFPI mRNA and protein expression.However,50,100,and 200 μmol/L puerarin blunted the augment of TF mRNA and protein expression and weakened the inhibition of TFPI mRNA and protein expression induced by ox-LDL(P<0.01).Conclusions Puerarin reduces HUVECs TF and TFPI mRNA and protein induced by ox-LDL.
