Objective To report the medium-term follow-up results for deep venous thrombosis(DVT) after total knee arthroplasty(TKA).Methods Between July 2003 and March 2004,55 patients(63 knees)who had had TKA were followed up for DVT.In follow-ups 1 to 2 weeks after TKA,their clinic symptoms,Doppler ultrasonograms and venograms were analyzed.In the following out-patient follow-ups done at every six months,we observed their clinic symptoms and Doppler uhrasonograms for the operated lower extremity.Venography was done only for those who had severe DVT symptoms.Results The venography one week after TKA conformed that DVT occurred in 34 patients(41 knees,61.8%).Two weeks after operation,DVT vanished in 12 cases,but deterio- rated to the proximal part in two cases.The follow-ups averaged 36.6 months(range,32 to 40 months).The results at five time points showed that the incidence of DVT did no decrease with lapse of time(P>0.05).Conclusion No matter whether DVT occurs in the perioperative period,incidence of DVT in the medium term varies little.

OBJECTIVE:To investigate the effects of selenium(Se)and/or vitamin E(VE)on the NO and NOS in heart,liver,kidney and serum of experimental hyperlipidemic rats.METHODS:SD rats were divided into5groups,administreated by Se and/or VE.After4weeks,the NO contents and NOS activities in heart,liver,kidney and serum were assayed by NO kit and NOS kit respectively.RESULTS:NO contents and NOS activities could be reduced in heart,liver,but increased in serum and kidney by high-fat feed(HFF).Meanwhile,VE and/or Se could increase the NO contents in all the experimental samples and NOS activities in heart,liver and kidney(P

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.

In order to determine the suitable harvest time of Dendrobium officinale from different regions in Yunnan province, the drying rate, mannose and glucose peak area ratio, extract, contents of polysaccharide and mannose of D. officinale samples collected from six producing areas in Ynnnan province were determined. The results indicate that drying rate and the contents of polysaccharide and mannose arrived the peak from January to April, extract reached a higher content from September to December, and mannose and glucose peak area ratio from October to February of the coming met the requirment of the Chinese Pharmacopoeia. Hence, the suitable harvesting time of D. officinale in Yunnan province is from December to February of the coming year,according to the experimental results and the request of the Chinese Pharmacopoeia.

The marine biological source of mineral drugs recorded in Chinese Pharmacopoeia (2010 version) mainly including pearl, nacre, clam shell, common oyster shell, ark shell, cuttle bone, and sea-ear shell are widely used in clinical. Calcium carbonate and a small amount of protein are the main components in this type of drugs. In this paper, a systematical and comparable study were carried out by determination of calcium carbonate by EDTA titration method, the crystal of calcium carbonate by X-Ray powder diffraction and the total amino acids (TAAs) of the hydrolyzed samples by ultraviolet spectrophotometry method. As a result, the crystal structure is calcite for common oyster shell, mixture of calcite and aragonite for nacre and sea-ear shell, aragonite for the other drugs. The content of calcium carbonate ranged from 86% to 96%. Cuttle bone has the highest amount of TAAs among the seven drugs which reached 1.7% while clam shell has the lowest content of 0.16% on average. In conclusion, an effective method was developed for the quality control of marine mineral drugs by comprehensive analysis of calcium carbonate and TAAs in the seven marine mineral drugs.

In this paper, the new carbon nanotube modified glassy carbon electrode (F-CNTs/GCE) was prepared to establish a new method for studying the molecular interaction mechanism between baicalin metal complexes (BMC) and bovine serum album (BSA), and the principle of this method was discussed deeply. Under the physiological condition, the thermodynamics and kinetics properties of interaction between BMC and BSA were studied by cyclic voltammetry (CV) to inference their molecular effective mechanism. The results show that the presence of F-CNTs can accelerate the electron transfer, and better response signal was showed in the BMC/BMC-BSA system. The detection of interaction of BMC-BSA used new method show that BMC-BSA generates stable thermodynamically non-covalent compounds, and the obtained average binding sites of BMC-BSA were 1.7; the number of electron transfer in BMC/BMC-BSA reaction process was 2, and non electroactive supramolecular compounds of BMC-BSA were generated by this interacting reaction. The relevant research work provides a new way to study the molecular mechanism for the interaction of drugs with protein, and with a certain reference value for discussion on the non covalent interactions.
