The policies of healthcare big data and their common and respective characteristics in USA, Britain, France, Japan, Republic of Korea, and Singapore were analyzed in aspects of their strategic planning, infrastruc-ture construction, R&D of key technologies, professional training, and privacy protection with 5 suggestions put for-ward for improving the policies of healthcare big data in China , namely transforming thinking , establishing opera-tional systems, working out construction criteria, building platform for big data sharing, and attaching importance to professional training .

Objective:To evaluate the effect of Oravive on remineralization and anti-demineralization ability with a laser fluorescence system.Methods:60 premolar specimens with artificial caries lesion were divided into three groups randomly.Samples were treated with Oravive,fluoride dentifrice and distilled water for 1 h,then etched for 24 h.A laser fluorescence system was used to make a quantitative record.Results:Oravive showed a statistically significant effect on remineralization and anti-demineralization ability.There was significant difference between Oravive and fluoride dentifrice on remineralization,but no difference on anti-demineralization.Conclusion:Oravive has good remineralization and anti-demineralization effects.Oravive is better than fluoride dentifrice on remineralization but equivalent to it on anti-demineralization.

AlM: To study the therapeutic effect of external-route microsurgery forrhegmatogenous retinal detachment.
METHODS: ln 55 patients ( 55 eyes ) with rhegmatogenous retinal detachment, drainage of subretinal fluid, examination of locating the holes, sclera cryotherapy, scleral buckling, and vitreous cavity injection of filtrated air were performed under surgical microscope.
RESULTS:The retinal reattachment occurred in 50 cases after the primary surgery. The final rate of reattachment was 91% during 6 - 12mo follow - up. The retinal reattachment occurred in 1 case ( recurrent retinal detachment) after the secondary surgery and in 4 cases ( recurrent retinal detachment ) after vitrectomy. The eyesight was improved with different degrees in 55 cases.CONCLUSlON: The external- route microsurgery for rhegmatogenous retinal detachment is simple, safe and effective.

Objective Establish a laboratory quality control system to ensure accurate and reliable test data and to contrapose the influence of error factors in current detection methods for urinary iodine measurement. Methods The results of reagent blank absorbance value and uric iodine standard materials were collected, then their relevant technical indexes such as mean, standard deviation, control limit, auxiliary line were worked out. Then the quality control chart of blank test and the relative error control chart were made base on these technical indexes. And different iodine concentrations (high, middle and low concentration) were tested and their mean,relative reduction difference value, weighted mean value and critical limit Rc value were calculated, and then critical limit Rc value precision control chart was made. Results The range of absorbance of blank control test was 1.183 to 1.553. And the limit of the accuracy control Rc value was 0.0883, 0.0572, respectively, when the concentrations of urinary iodine was 0～ < 150 μg/L and 150 ～ 300 μg/L. The control limit of the relative error was 9.3%. Conclusions The method of quality control chart could be satisfactorily applied to identify the quality of the analytical results of urine iodine, and ensure the results of the urine iodine reliable and authentic.

Objective_To investigate whether hUCMSCs undergo malignant transformation when exposed to MCF-7B breast cancer microenvironment and whether the abnormal activation and over expression of STAT3 play an impor-tant role in this transformation.Methods_The experiment was divided into three groups:blank group ( hUCMSCs were separately cultured),experimental group(hUCMSCs were indirectly co-cultured with MCF-7B breast cancer cells),positive control group(MCF-7B breast cancer cells were separately cultured).Morphology of cells was detec-ted by invertedmicroscope.Cell cycle was detected by flow cytometry.The mRNA expression of STAT3, c-Myc and Bcl-xL was tested by real-time PCR.The protein expression and location of p-STAT3,c-Myc and Bcl-xL were detected by immunofluorescence.The protein expressions of p-STAT3,STAT3,c-Myc and Bcl-xL were also meas-ured by Western blot.Results_The experimental group cells showed typical morphology of the tumor cells.The cells proportion of experiment group in G1 phase was significantly lower than that of the blank group(P<0.05),but which in S and G2 phase were significantly higher than those of the blank group(P<0.05).The mRNA expression levels of STAT3 ,c-Myc and Bcl-xL in experimental group was significantly higher than those in blank group ( P<0.05).p-STAT3,STAT3,c-Myc and Bcl-xL protein were significantly higher than those of the blank group(P<0.05),and they were mainly located in the nuclei.The protein expression of STATS also showed significant changes in experimental group.Conclusions_hUCMSCs trends to malignant transformations when exposed to MCF-7B breast cancer microenvironment.The abnormal activation and over expression of STAT3 are of important factors leading to the malignant transformation of hUCMSCs.

Standards of TCM information plays a fundamental and critical role in TCM informatization. In recent years, the standardization of TCM information has made a series of tremendous progress. This article introduced the major work progress of TCM terminological standardization and TCM data standardization in China, and status of TCM information standardization in International Organization for Standardization and World Health Organization. The existing problems in the construction of standardization of TCM information were discussed and suggestions were proposed to solve problems: to build the basic framework of standard system of TCM information; to cultivate professionals for the researches on the international standards of TCM information; to further explore the theories and methods about standardization of TCM information.
