Objective To investigate new cases of endemic cretinism in high-risk areas of Inner Mongolia, the prevalence of endemic goiter, the implementation of comprehensive measures, and to provide scientific basis for developing control strategies against iodine deficiency disorders (IDD). Methods In 2007 and 2008, a search for new cretin cases was conducted among children under the age of 10 in 11 historical serious epidemic cretinism prevalent areas of Songshan district, Keshiketeng qi, Kalaqin qi, Zhalaite qi, Zhuozi county,Liangcheng county, Qingshuihe county, Helin county, Dongsheng district, Zhungeer qi and Yinjinhuoluo qi. Three to 5 towns were selected in each qi(county, district) and 3 to 5 village primary schools were selected in each town.One hundred and twenty to 200 children aged 8 to 10 were selected in each school to inspect thyroid by B ultrasound and palpation and to test intelligence and urinary iodine. Two villages were selected in each town and 30 households were selected to determine urinary iodine of housewives and salt iodine. Results A total of 56 cases of suspected cases of endemic cretinism were found from the 11 counties but no case was confirmed. The goiter rate of children aged 8 to 10 was 5.2% (309/5922) by palpation and 4.3% (252/5922) by B-ultrasound. The median urinary iodine of children aged 8 to 10 was 241.5 μg/L, and urinary iodine was 100 to 300 μg/L, accounted 65.9%(3901/5920). Median urinary iodine of the 9 Qis(counties, districts) was in the range of 200 and 300μg/L.Higher than 5% of the 11 Qis(counties, districts) with urinary iodine lower than 50 μg/L was zero. Higher than 10% of the 11 Qis(counties, districts) with urinary iodine lower than 100 μg/L was 1. The median urinary iodine of housewives was 225.6 μg/L, and lower than 50 μg/L accounted for 2.2%(35/1597). Higher than 10% of the 11 Qis(counties, districts) with urinary iodine lower than 100 μg/L was 4. A total of 2109 households were investigated and 97.45%(2055/2109) of them ate iodized salt and 2.55%(54/2109) of them ate non-iodized salt. Conclusions In the 11 investigated counties, goiter rate of children has decreased to less than 10%, and no new cretin was found. It could be concluded that the fulfillment of prevention and control of IDD is effective. The iodine nutrition of children and women of childbearing age is in an adequate level. The coverage rate of iodized salt has maintained at a higher level, the sales network is sound, the salt price is reasonable and salt is easy to get and the children's intelligence is protected effectively. But, the health education about IDD is still weak, need to be reinforced.

0.05).Conclusion The application of oxygen inhalation with a special facial mask during propofol-sedated gastroscopy appears to be more safer than that of oxygen inhalation via snuffle tube.

SW872 preadipocytes were cultured and induced to differentiate by oleic acid in vitro.The levels of adiponectin and its receptors (AdipoR1 and AdipoR2) mRNA were measured by semiquantitative RT- PCR.The concentration of adiponectin in the culture medium was assayed by ELISA.The results showed that rhIL- 6 could inhibit adiponectin,AdipoR1 mRNA expressions and adiponectin secretion in SW872 adipocytes in a time- and dose-dependent manner,but did not influence adipoR2 mRNA expression.

The sfa1 gene encoded a bifunctional enzyme with the activities of both alcohol dehydrogenase and glutathione-dependent formaldehyde dehydrogenase in Saccharomyces cerevisiae.The gene disruption cassette produced by PCR using the same long oligonucleotides which comprise 19 or 22 nucleotides complementary to sequences in the templates(pUG6 and pUG66 marker plasmid)at 3' end and 45 nucleotides at 5' end that annealed to sites upstream or downstream of the genomic target sequence to be deleted.After two linear disruption cassettes with a Cre/loxP mediated marker were transformed into the cells of Saccharomyces cerevisiae YS-1,the positive transformants were checked by PCR to correct the integration of the cassette and concurrent deletion of the chromosomal target sequence.Once correctly integrated into the genome,the select marker can be efficiently rescued by transformating the plasmid pSH47 into YS-1 and inducing the Cre expression with a Cre/loxP-mediated marker removal procedure.The expression of the Cre recombinase finally resulted in the removal of the marker gene,leaving behind a single loxP site at the chromosomal locus.The diploid mutant YS-1-sfa1 was generated,which could enhance the output of ethanol with 8.0% by shaking culture in flask compared with the original strain YS-1.

OBJECTIVETo explore the effect of reduction and fixation with multi-Kirschner wires for treatment of Lisfranc fracture-dislocations.

METHODSThere were 49 patients (37 male and 12 female aged from 20 to 28 years old) involved in the study. According to the Myserson damage typing, type A in 12 cases, B1 in 3, B2 in 28, C1 in 4 and C2 in 2. Kirschner wires were applied to fix and reconstruct the three-column in three directions according to the structural characteristic of midfoot. Reconstruction of three-column needed not only to reduce and to fix every single column, but also to establish union of the columns.

RESULTSAccording to the evaluation of AOFAS for midfoot, 14 cases were excellent (90 to100), 22 cases good (80 to 89), 8 cases fair (70 to 79) and 5 cases poor (60 to 69), with an average score of 84.200+/-9.663.

CONCLUSIONThe diagnosis and treatment of Lisfranc fracture-dislocations should comply with the theory of three-column reconstruction of foot arch, which can achieve the static balance of biomechanics and provide a stable environment for healing of fracture and soft tissue. Reduction and fixation with multi-Kirschner wires is an effective treatment method for Lisfranc fracture-dislocations.

OBJECTIVETo explore evolution rules of phlegm and blood stasis syndrome ( PBSS) in hyperlipidemia and atherosclerosis (AS) using NMR-based metabolic profiling and metabonomic approaches based on formulas corresponding to syndrome.

METHODSTotally 150 SD rats were divided into the normal group, the model group, the Erchen Decoction (ED) group, the Xuefu Zhuyu Decoction (XZD) group, the Lipitor group, 30 in each group. The hyperlipidemia and AS rat model was duplicated by suturing carotid artery, injecting vitamin D3, and feeding with high fat diet. ED and XZD were used as drug probes. Blood samples were withdrawn at week 2, 4, and 8 after modeling. Blood lipids, blood rheology, histopathology and metabolomics were detected and analyzed. Results Results of blood lipids and pathology showed hyperlipidemia and early AS rat models were successfully established. At week 2 after modeling, levels of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) significantly increased, which reached the peak at week 4 and maintained at higher levels at week 8. ED exerted obvious effect in improving TC and LDL-C levels of early models, while XZD could greatly improve levels of TC and LDL-C of late models. Rheological results showed at week 2, there was no significant difference in whole blood viscosity, plasma viscosity, or hematocrit between the model group and the normal group (P > 0.05). At week 4 partial hemorheological indicators (such as plasma viscosity) were abnormal. Till week 8 whole blood viscosity, plasma viscosity, and hematocrit were significantly abnormal (P <0. 05, P < 0.01). As time went by, whole blood viscosity, plasma viscosity, and hematocrit showed gradual increasing tendency in the ED group, while they showed gradual decreasing tendency in the XZD group. Results of metabonomics showed significant difference in spectra of metabolites between the normal group and the model group. As modeling time was prolonged, contents of acetyl glucoprotein and glucose in the model group increased in late stage, which was in. line with results of blood lipids and hemorheology. ED showed more obvious effect in early and mid-term modeling (at week 2 and 4), and increased contents of partial metabolites (such as choline, phosphatidyl choline, glycerophosphocholine), but these changes in the XZD group were consistent with those of the model group. In late modeling (at week 8) XZD showed more obvious effect in improving contents of lactic acid, acetyl glycoprotein, LDL, creatine, choline, and glucose.

CONCLUSIONSED and XZD not only showed regulatory effects on lipid disorders, but also could improve dysbolism of Chos. In formulas corresponding to syndrome, damp-phlegm was main pathogenesis of hyperlipidema and AS in early and mid stages. Blood stasis syndrome began to occur along with it progressed. Phlegm can result in blood stasis and intermingles with stasis. Phlegm turbidity runs through the whole process.

The expressions of StAR (steroidogenic acute regulatory protein) mRNA in testes from 7,14,23 and 37 day-old piglets were studied by tissue in situ hybridization. The results indicated that in the testes of piglets, StARmRNA was expressed in Leydig cells of pig testes. The expression level of StARmRNA was lower in 7 days piglets but higher in 14,23,37 days. The results indicated that StAR gene played an important role in steroid biosynthesis.

Objective To report the clinical effect of free transplanting for soft tissue defects pedieled with high site cutaneous branches of the transverse branch of lateral cirumflex femoral artery.Methods Cu- taneous branches of the descending branch of lateral circumflex femoral artery were found small or abscent in 7 patients.The anterolateral femoral skin flap was pedicled with high site cutaneous branches of the transverse branch to repair the soft tissue defects of the arm,hand,leg and foot,rather than with the descending ones. The size of the flap ranged from 15 cm?6 cm to 28 cm?13 cm,with part muscle valve,iliotibal tract and lat- eral femoral cutaneous nerve.The fractures were performed with internal or external fixation.Results All of the anterolateral femoral skin flap survived well postoperatively in the 7 cases and had good appearance and sensation at one stage.The function of the repaired extremities recovered well.Conclusion The anterolat- eral femoral skin flap pedicled with high site cutaneous branches of the transuvrse branch of lateral circumflex femoral artery has many advantages of good blood supply and large size.The flap was secluding,and can be taken with some muscle and lateral femoral cutaneous nerve.When cutaneous branches of the descending branch of lateral circumflex femoral artery is small or abscent,the anterolateral femoral skin flap with high site cutaneous branches of the transverse branch of lateral circumflex femoral artery is an optimal alternative.
