OBJECTIVETo explore clinical effectiveness of internal fixation and semi-shoulder arthroplasty in treating proximal humerus comminuted fractures in elderly.

METHODSFrom October 2009 and October 2011, 32 patients aged over 60 years old with three and four-part fractures of proximal humeral were treated with internal fixation (20 cases) and semi-shoulder arthroplasty (12 cases). In internal fixation group, there were 6 males and 14 females aged from 63 to 82 years old (ranged, 71.50 +/- 5.45), 8 cases with three-part fracture and 12 cases with four-part fracture, and treated with open reduction and locking plate internal fixation. While in semi-shoulder arthroplasty group, there were 4 males and 8 females aged from 61 to 85 years old (ranged, 72.80 +/- 6.80), 5 cases with three-part fracture and 7 cases with four-part fracture, and treated with semi-shoulder arthroplasty. Postoperative complications were observed, EQ-5D was used to evaluate quality of life, and Constant-Murley score was used to assess functional outcomes.

RESULTSAll patients were followed up from 12 to 24 months with an average of 18 months. All injuries were healed at stage I . Two cases in internal fixation group occurred severe complications, including 1 case with screw fracture, 1 case with avascular necrosis of humeral head. EQ-5D in interal fixation group and semi-shoulder arthroplasty group were respectively 0.65 +/- 0.12, 0.67 +/- 0.12, Constant-Murley score respectively was 63.20 +/- 11.35 and 66.80 +/- 11.96, and with no statistical meaning between two goups (P>0.05).

CONCLUSIONThere is no difference in qulity of life and functional recovery for the treatment of proximal humerus comminuted fractures by open reduction and internal fixation and semi-shoulder arthroplasty. However, the complication rate in semi-shoulder arthroplasty was lower than that of internal fixation group.

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.

The full length cDNA encoding peroxisomal membrane protein from Chaetomium globosum was cloned using RACE technology and the sequence in cDNA library of C. globosum in GenBank ( Accn: BP099709). The 747bp full length cDNA encoding peroxisomal membrane protein allergen (pero) gene was assembled with 412bp 3'and 508bp 5'RACE products. The open reading frame was 501 bp encoding 166 amino acids. The molecular weight of the protein was 17. 5kDa and its theoretical isoelectric point was 5.75. The pero gene was amplified using specific primers of cDNA 5'and 3'untranslated region, sequence analysis indicated that the gene have 3 exons and 2 introns. ClustalX analysis revealed that amino acids sequence of pero gene from C. globosum and Neurospora crassa shared 83% high similarity. To construct pET28a-pero expressive plasmid, pero gene was inserted into pET28a expressive vector. Escherichia coli BL21 transformed by pET28a-pero plasmid was induced with IPTG. The protein expression was analyzed with SDS-PAGE. A 21kDa pero fusion protein representing the pero gene was expressed in recombinant E. coli BL21. The sequences of cDNA,DNA and deduced amino acid of the pero gene from C. globosum were submitted to GenBank (Accn: AY555771, AY584753,AAS66898).

Objective: By studying the pharmacokinetics in dogs' vivo of Gansu Capsule (sustained release), evaluate slow release effect in vivo of Gansu Capsule (sustained release). Methods: To take gallic acid as marker component, which is one of effective components, After taking Gansu Capsule (sustained release) and Gansu Capsule (common), to adopt high performance liquid chromatography to determinate the blood concentration of acid pyrogallol in dogs at different time. Results: Both Gansu capsule (sustained release) and Gansu Capsule (common) coincide one compartment model. It suggested that Gansu Capsule (sustained release) had remarkable effects of slow release and could maintain higher blood concentration in vivo longer the slow release effect of Gansu Capsule (sustained release) in vivo that could be evaluated by accumulative releasing percentage in vito. Conclusion: Gansu Capsule (sustained release) had good slow release effect in vivo and vitro.
