The control group was treated with PPI trigeminy therapy, and the treatment group was treated with self-designed gastritis granule combined with PPI trigeminy therapy. Both groups were treated for continuous four weeks. Results The eradication rate of Hp in treatment group was significantly higher than that of the control group (P<0.05) .Conclusion The treatment of self-designed gastritis granule on chronic gastritis accompanied by gastric mucosa atrophy and erosion has effective results.

[Objective]To research the influence of spinal cord blood flow(SCBF) and the evoked potential(EP) by the extramarrow impacting and to explore the correlation and regularity between the spinal cord blood flow and evoked potential after spinal cord injury.[Method]Normal 120 SD rats were randomized into 4 groups,with 30 in each.Group A was the control group.In groups B,C,D,impacts of 10,15,20N were given to lamina respectively.The blood flow of impacting position and evoked potential were observed at different time points including 0 min,1 h,6 h,1 d,6 d,12 d,24 d.[Result]The blood flow of spinal cord represents a dimning trend with the impacting load raising.The blood flow of group A,had no marked change,the SEP and MEP also.The blood flow of group B represented a temporaly lowing,then recovered normal,the SEP and MEP also.The blood flow of group C and D represented a continuous lowing,then slowly raising.The group C recovered normal at 24d,the group D still lower than normal.[Conclusion]The impact load to lamina can influence the spinal cord function through altering the spinal cord blood flow.There is evident correlation between the SCBF and EP.

Objective To discuss the technique of supraorbital transeyebrow keyhole approach microsurgery for sellar tumors. Methods A total of 33 cases of sellar tumors were treated in this hospital from July 2001 to June 2004. The resection of the tumor was achieved by way of a supraorbital eyebrow minicraniotomy through a 2.0 cm ? 3.0 cm keyhole approach. The surrounding cisterns of the sellar area were opened to expose underlying structures under microscope at proper angles. Results Of 26 cases of hypophysoma, a total resection was performed 19 cases, and a subtotal resection in 7 cases. Of 4 cases of craniopharyngioma, a total resection was performed 3 cases, and a subtotal resection, 1 case. One case of meningioma received a total resection, and 1 case of optic chiasm glioma underwent a partial resection. Postoperatively, transitory diabetes insipidus was observed in 5 cases, and grand mal epilepsy occurred in 1 case. There were no infection or bleeding after the operation. All the 33 cases were followed for 4~36 months (mean, 27 months). No recurrence of tumors was seen in the 24 cases of total resection. Postoperative radiotherapy was given in 7 cases of subtotal resection of hypophysoma, 1 case of craniopharyngioma, and 1 case of optic chiasm glioma, and no apparent enlargement of tumors was found. Conclusions Supraorbital transeyebrow keyhole approach microsurgery minimizes the unnecessary exposure of the brain and postoperative complications.

Objective To investigate the effects of carboxymethyl-chitosan (CM-CH) on keloid fibroblasts (KFB) proliferation and collagen synthesis. Methods Keloid fibroblasts were isolated from fresh keloid tissue and cultured. The effect of CM-CH on proliferation was examined by MTT assay. The synthesis of collagen was evaluated by hydroxy proline (HP) colorimetric analysis. Results The fibroblasts were treated with CM-CH at concentration of 10 ?g/ml, 50 ?g/ml, and 100 ?g/ml 48h and 72h after treatment, and all of the three concentrations showed inhibitory effects significantly (P0.05) at 200 ?g/ml concentration after 24h, 48h, and 72h. CM-CH at concentration of 10 ?g/ml, 50 ?g/ml, and 100 ?g/ml after treatment for 48h on KFB could markedly decrease the synthesis of collagen (P

Chitosan, a linear polysaccharide, is obtained by chitin N deacetylation. Its ?(1 4) glucosidic bond is not stable and breaks easily in acid condition. In this study, chitosan of different molecular weights(MW) was prepared by acetic acid degradation. Chitosan was dissolved at 3%(w/v) concentration in 1%(v/v) acetic acid and the solution was dried at 50 degree C. We get chitosan membranes of different MW after neutralization with aqueous NaOH. The membranes are transparent, elastic and have good intensity. The permeability studies on chitosan membranes were going on with a permeable install made by our laboratory. It was determined by the transmission concentration of NaCl, L Tyr, glucose and calf albumin. We compared the permeability property with different MW chitosan membranes. The result implied that all of the four samples could permeate through the chitosan membranes. And the permeability property of the membrane increased with the chitosan MW decreaseing.
