Objective To understand the situation of iodine deficiency disorders of Cangzhou city, Hebei province, in order to provide the scientific basis for prevention and control of iodine deficiency disorders. Methods From 2007 to 2009, dynamic monitoring of iodine deficiency disorders was carried out in low iodized salt coverage places Hejian city and Xian county. Nine towns were randomly chosen in each county, 4 administrative villages were randomly selected in each town, 8 household salts were tested in each village. Every year, 1 - 3 copies of residents water samples were collected for determination of iodine; more than 100 students age 8 - 10 years old were checked the situation of goiter and urinary iodine, more than 40 students selected were measured iodine content of salt from their home; more than 50 women of childbearing age 18 - 40 years were tested of urinary iodine. Thyroid was examined with palpation; water iodine and urine iodine concentration were measured with arsenic-Ce catalytic spectrophotometry; salt iodine was detected by direct titration. Results From 2007 to 2009,median household salt iodine were 4.3,15.9,3.6,18.4,4.6,11.7 mg/kg in Hejian city and Xian county, respectively,iodized salt accounted for 34.03% (98/288), 78.82% (227/288), 29.86% (86/288), 84.72% (244/288), 37.15%(107/288),49.31% (142/288), respectively, the consuming rate of iodized salt were 27.08% (78/288),36.46%( 105/288 ), 28.13% (81/288 ), 49.31% ( 142/288 ), 37.15 % ( 107/288 ), 30.90% ( 89/288 ), respectively. Ten samples of drinking water were tested, water iodine were 5.5 - 34.4 μg/L. From 2007 to 2009, the goiter rate of students aged 8 - 10 years old was below 5%, the median of urinary iodine were 138.1,176.6,112.0 μg/L, < 100 μg/L ratio were 31.6% ( 65/206 ), 25.0% ( 52/208 ) and 44.4% (91/205 ). The median of urinary iodine of child-bearing age women were 167.3,164.2,78.1 μg/L, < 100 μg/L ratio were 28.7%(29/101 ), 19.2%(20/104) and 60.0%(60/100).Conclusions In areas with low coverage of iodized salt, iodine nutrition level are affected, the child-bearing age

Objective To explore the method of culture of rat adipose-derived stem cells(ADSCs) and differentiation induction into myoblasts. Methods Adipose tissues were obtained from SD rats,and were isolated by enzyme digestion and cultured into ADSCs.The expression of surface antigen CD90,CD105 and CD34 was detected by immunofluorescence and flow cytometry.ADSCs of the second passage with logarithmic growth were obtained,and culture media containing 5-azacytidine(5-aza) and basic culture media were employed for cells in induction group and control group,respectively.The induction lasted for 7 d,14 d,21 d,28 d and 35 d,respectively.Cell growth and cell morphology were observed by inverted phase contrast microscope,and immunofluorescence and flow cytometry were utilized to detect the expression of myoblast specific antigens desmin and myosin. Results ADSCs were successfully isolated and cultured,and were identified to be stem cells.On the 28th day of induction,cells in induction group displayed "swirl" morpholgy,and multinucleation was observed.It was revealed by immunofluorescence and flow cytometry that the highest expression rates of desmin and myosin were 52.57% and 50.04%,respectively on the 28th day of induction,while there was no expression before induction and in control group. Conclusion ADSCs can be isolated and cultured from rat adipose tissues,and can further differentiate into myoblasts after induction by culture media with 5-aza.The expression of myoblast specific antigen is the highest on the 28th day of induction.

Background The injury or surgery of cornea cause the proliferation of corneal stromal cells and scar formation.Recent research showed that cureumin can obviously reduce the degree of fibrosis of tissue.But if curcumm play inhibitory effect on corneal keratocytes fibrosis is rarely reported.Objecttve This studv was to investigate the effect of curcumin on the transformation of corneal keratocytes into fibroblasts in vitro and further explore the antifibrotic effect of curcumin on corneal keratocytes.Methods The murine corneal keratocytes from 150 BALB/c mice were isolated and primary culture in DMEM culture medium containing 10% fetal bovine serum and then divided into blank control group(inducer group,CG),low-dose group(CG+7.5 mg/L curcumin),mediumdose group(CG+10.0 mg/L curcumin),high-dose group(CG+12.5 mg/L curcumin),non-inducer group.Seven days following intervention,the expression of cell markers such as keratocan,aldehyde dehydrogenase(ALDH),decorin and fibronectin-1 in keratocytes were analyzed by RT-PCR.The effect of curcumin on cultured murine corneal keratocytes proliferation was evaluated by MTS technique.The expression of fibronectin-1 in murine cornea was investigated by immunofluorescence assay.Results The primarily cultured keratocytes showed tlIe fusiform-like shape with the abundant cytoplasm and big nuclei.In the presence of curcumin,the mRNA levels of keratocan and ALDH were down-regulated and those of CD90 and decorin were up-regulated,showing the significantly differences with the increase of dose(P<0.05),but the expression pf fibronectin-i was not obviously changed with the alteration of dose of curcumin. MTS showed that the inhibitory rates of curcumin on keratocytes in 10.0 mg/L and 2. 5 mg/L groups were enhanced in comparison with 7.5 mg/L group, showing statistically significant difference among three groups( F = 956.00, P<0.05). The expression of fibronectin-1 was found in the corneal keratocytes with the red fluorescence in stroma. Conclusion Curcumin can inhibit the fibrosis of corneal keratoeytes in a dose-dependent manner. These results offer a preliminary theoretical basis for the application of curcumin in controlling corneal scar formation during wound healing.

OBJECTIVETo improve the outcome of the face-lift with a craniofacial contouring procedure.
METHODSThirty-seven patients aged 29-53 years (31 in female, 6 in male) were treated through a bicoronal incision. The facial tissue was lifted through a subperiosteal procedure and the facial skeleton was remodeled in three dimensions by osteotomies.
RESULTSThe results were satisfactory after the 3-12 months of the follow-ups.
CONCLUSIONSThe Face-lift combined with the facial aesthetic sculpturing may be more effective for the aging-face rejuvenating.

Objective To construct a technical platform for scarless gene modification of Yersinia pestis and to study the functions of its specific genes.Methods The resistance fragment, including upstream and downstream homologous arms of targeted regions, was reamplified by asymmetric PCR.The amplicons were introduced into Y.pestis harboring plasmid pKD46.With the induction of L-arabinose,the recombinant related enzymes: Exo, Beta and Gam, were expressed to guide the homologous recombination.A donor plasmid, pKSI-1, which carried the desired modification fragment flanking by I-SceⅠ recognition sites, was introduced into Y.pestis as the second step of λ-Red recombination with the help of pREDTKI.Results and Conclusion Two mutant strains:△waaA and waaA(△9nt), were successfully constructed for Y.pestis strain 201.Scarless modification introduces no extra modification to the genome, and it is ideal for comprehensive functional genomic studies.

OBJECTIVETo discuss the TCM pattern classification and measurable diagnosis criterion of the protracted symptoms of heroin-addiction abstinence (PSHAA).
METHODSThrough literature review and clinical study, the concept of TCM patterns and diagnostic standard were established, and a TCM pattern scale for quantitatively analysis of PSHAA was formulated. The scale were used on the clinical investigation on the abuser for 5 times on day 15, 30, 60, 90 and 120 after abstinence. Then the TCM patterns of PSHAA was classified using methods of DME and quantitative diagnosis, to create a corresponding scale of diagnostic indexes referring maximum likelihood method.
RESULTS(1) The TCM patterns of PSHAA commonly seen were Toxin-stasis accumulation (TSA) with Qi-blood insufficiency, TSA with Qi-yin deficiency, TSA with Yin-deficiency and Fire-excess and TSA with Yin-Yang deficiency. (2) The retrospective and prospective verification of the scale of diagnostic indexes showed it has high sensitivity and speciality, with low rates of misdiagnosis and of missed diagnosis.
CONCLUSIONIt is feasible to develop measurable diagnosis on the TCM patterns of PASAA using DME method and measurable diagnostic methods. The scale of diagnostic indexes formulated with the maximum likelihood method of quantified diagnosis has a certain clinical practicability.
