Objective To review the surgical managements of patients with traumatic false aneu- rysms in the extremities.Methods From January 1990 to April 2006,17 patients with traumatic false aneurysms in the extremities were admitted into our hospital.Fourteen patients were treated by vascular repair including vascular repair in seven cases,end to end anastomosis in one,synthetic grafting in one, autogenous vein grafting in one,and direct ligation in four.Three patients were treated nonoperatively, but with local compressive dressing.Results There were no deaths or gangrenes in all cases.The clinical manifestations vanished after the treatment.The mean follow-up period was 13.2 months.The function of the injured extremities recovered satisfactorily.Conclusion Different types of traumatic false aneurysms should be managed by different therapeutic procedures after the diagnoses is made.

Aim To study relative bioavailablity of cefaclor effervescent tablets in healthy volunteers. Methods According to the crossover design, A volunteers were each orally given a single does of the 0.75 g cefaclor effervescent tablets and cefaclor capsules with an interval of 5 days between the two formulations.The plasma concentrations of the drug were determined by RP-HPLC.Pharmacokinetic parameters were obtained by ATPK programe,and calculated on the basis of open single compartment model.Results After a single oral dose, the peak levels in plasma averaged Cmax(31.27?5.81)?g?ml-1 and(30.56?5.25) ?g?ml-1 at (0.58?0.12)h and(0.73?0.17)h and AUC0～4(35.48?4.65) ?g?h?ml-1 and (35.89?2.90) ?g?h?ml-1 for tablet and capsule,respectively. Conclusion The result shows that two formulations are bioequivalence.

Objective To investigate the significance of galactose galectin-3(Galectin-3)and matrix metalloproteinase-2(MMP-2)expression in gliomas patients and thire role in process of gliomas' malignancy development. Methods Immunohistochemistry was used to detect Galectin-3 and MMP-2 protein expression in 5 normal brain tissue and 40 patients with different grade gliomas. According to positive cells number of Galectin-3,MMP-2 in tumor cells under a microscope,to determine the expression,and the positive index(LI)which came from the percentage of the positive cell number out of the total cell number was to expressed the number of positive cell. Results Galectin-3 and MMP-2 protein expression in normal brain tissue were negative. In glioma tissues,Galectin-3 was mainly expressed in the cytoplasm and membrane of tumor cells. In 23 glioma tissue withⅠor Ⅱ grade,9 cases(39. 13% )was positive and the LI values was(5. 65 ± 3. 47)% in terms of Galectin-3 expression. In Ⅲ,Ⅳ grade glioma specimens,the positive rate of Galectin-3 expression was 76. 47%(13 / 17), and LI value was(27. 88 ± 22. 13)% . The difference of Galectin-3 expression and LI value were significant between specimens with Ⅰ,Ⅱ grade and Ⅲ,Ⅳ significant( χ2 = 4. 101,t = 4. 105;P < 0. 05). In human gliomas,MMP-2 expression protein was mainly expressed in tumor cells and vascular basement membrane of the endothelial cell cytoplasm. In 23 glioma tissue with Ⅰor Ⅱ grade,9 cases(39. 13% )was positive and the LI values was(5. 91 ± 4. 78)% in terms of MMP-2 expression. In Ⅲ,Ⅳ grade glioma specimens,the positive rate of MMP-2 expression was 88. 24%(15 / 17),and LI value was(30. 06 ± 22. 94)% . The difference of MMP-2 expression was significant between specimens with Ⅰ,Ⅱ grade or Ⅲ,Ⅳ grade( χ2 = 7. 882,t = 4. 271;P< 0. 05). The linear correlation analysis showed that there was positively correlation between Galectin-3 and MMP-2 positive cells(r = 0. 800,P < 0. 05). Conclusion Galectin-3 and MMP-2 protein expression in Ⅰ,Ⅱgrade gliomas is significantly lower than those inⅢ,Ⅳ grade glioma,and they are positively related with the progress of malignant gliomas. Galectin-3 and MMP-2 protein can be used to evaluate or judge the malignant stage of human brain glioma.

A dispute about the decreasing-price problem of traditional Chinese medicine (TCM) has recently arisen. This article analyzes the statistical data of 1995-2011 in China, the results showed that the main responsibility of expensive health care has no direct relationship with the drug price. The price index of TCM rose significantly slower than the medicine prices, the production margins of TCM affected by the material prices has been diminishing since 1995, continuous price reduction will further depress profits of the TCM industry. Considering the pros and cons of raw materials vary greatly in price, decreasing medicine price behavior will force enterprises to use inferior materials in order to maintain corporate profits. The results have the guiding meaning to medicine price management.

Objective To explore the effect of L-carnosine on neuronal cell apoptosis in young rats with experimental febrile seizures(FS).Methods Forty 15-day SD rats were randomly divided into intervention group(n=30)and FS group(n=10).Warm water was used to induce 10 times FS.The intervention group was divided into E,G and H group,10 rats in each group.Intraperitoneal injection of L-carnosine(250 mg/kg)was separately given to the rats in E group,G group and H group respectively after 30,60 and 120 min of seizure.FS group were induced FS,but they were not given intervention.The rats were sacrificed at 12 hours after the last seizure.Neuronal cell apoptosis was determined by terminal eoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL)in situ cell death kit.TUNEL positive cells were stained and counted as apoptosis in hippocampus and cortex.Ultrastructural changes of apoptosis neurons were observed under the electron microscope.Results The neuronal cells apoptosis count was 25.37?1.95 in FS group,12.36?1.13 in E group,17.85?2.04 in G group,and 22.69?2.69 in H group.Neuronal apoptosis of FS group was apparently higher than that of interventional groups(F=10.75 P0.05).Under the electron microscope,neuronal damage on hippocampal CA1 area and dentate gyrus of FS group and H group was obviously higher than that of E group.Conclusions Early injection of L-carnosine would not only relieve neuronal apoptosis of repeated FS,but also play a role in the protection of neuronal cells.

OBJECTIVETo analyze the genetic polymorphism of 6 short tandem repeat (STR) loci on chromosome 7p14-15 and 8 STR loci on chromosome 12q13 in Chinese north Hans.

METHODSFluorescence-labeling polymerase chain reaction and capillary electrophoresis were used to analyze the genetic polymorphism of 100 randomly selected individuals from Chinese north Han nationality at 6 STR loci (D7S1808, D7S2250, D7S2251, D7S683, D7S656 and D7S528) on chromosome 7p14-15 and 8 STR loci(D12S1056, D12S1293, D12S83, D12S1655, D12S1662, D12S334, D12S137 and D12S102) on chromosome 12q13.

Methoxypoly (ethylene glycol)- block-poly (DL-lactide) (PELA) microcapsules containing bovine hemoglobin (BHb) were prepared by a W/O/W double emulsion-solvent diffusion process. The P50 and Hill coeffcient were 3466 Pa and 2.4 respectively, which were near to the natural bioactivity of bovine hemoglobin. The results suggested that polymer composition had significant influence on encapsulation efficiency and particle size of microcapsules. The encapsulation efficiency could reach 90% and the particle size 3 - 5 microm when the PELA copolymer containing MPEG 2000 block was used. The encapsulation efficiency and particle size increased with the concentration of PELA. Increasing the concentrations of NaCl in outer aqueous solution resulted in the increase of encapsulation efficiency and the decrease of particle size. As the concentration of stabilizer in outer aqueous solution increased in the range of 10 g/L to 20 g/L, the particle size reduced while encapsulation efficiency was increased, further increase of the stabilizer concentration would decrease encapsulation efficiency. Increasing of primary emulsion stirring rate was advantageous to the improvement of encapsulation efficiency though it had little influence on the particle size. The influence of re-emulsion stirring rate was complicated, which was not apparent in the case of large volume of re-emulsion solution. When the wall polymer and primary emulsion stirring rate were fixed, the encapsulation efficiency decreased as the particle size reduced.
