ABSTRACT
Tranexamic acid(TXA) as an antifibrinolytic drugs used to reduce the total knee arthroplasty(TKA) postoperative blood loss is a hot issue in recent years. Such as blood loss, hemoglobin, transfusion rate and other relevant indexs effected by the impact of total knee replacement have been studied and investigated by many scholars. There is no a gold standard about how to safely and effectively apply the TXA. Depending on the dose, TXA may be used by body weight or using 1.5 g or 3.0 g directly. Depending on the different route of administration, TXA may be intravenous infusion, topical application and oral medication. Depending on the using opportunity, TXA can be used preoperative, intraoperative, postoperative or combined application with different times. Without any increase in the chances of thrombosis after TKA, choosing the more scientific instructions to play the greatest utility TXA is a hot issue recently.
ABSTRACT
Objective To screen the antibacterial activity of Chinese traditional medicines against Yersinia pestis.Methods Six Chinese traditional medicines(Coptis Chinesis etc)were selected and extracted with pure water to make a concentration of 1 mg/L.Yersinia pestis strain 201 and EV 76 were used to determine the minimal inhibitory concentrations(MIC)of these selected medicines in vitro with liquid dilution method.Results Three herbs had inhibition effects on the strain 201 and EV76 in different extents,among which Rheum palmatum had the strongest effect and MIC was 0.025 00 mg/L.Furthermore,the Chinese traditional medicine had the same MIC on both strain 201 and EV76.Conclusions Chinese traditional medicines commonly used have inhibiting effect on Yersinia pesti.
ABSTRACT
A transmitting and receiving system used in high frequency ultrasound imaging is introduced and has been used for image collection of 10MHz, 20MHz and 50MHz HF ultrasonic imaging equipment. Its experimental results show that this transmitting and receiving system is capable of obtaining a better quality of medical images.

<p><b>OBJECTIVE</b>To evaluate the treatment effect of mandible fractures.</p><p><b>METHODS</b>Clinical data of 275 mandibular fracture patients of Tongchuan people's hospital were analysed.</p><p><b>RESULTS</b>(1) The systemic health of 27 non-surgery cases were influenced during the intermaxillary ligation and 3 cases of them had deformity of maxillofacial region. (2) In the surgery group, 5 of 73 cases fixed by steel wire had disorder of occlusion, 6 of 169 cases fixed by titanium mini plate accepted secondary operation of removing the plates, and 6 cases fixed by bioabsorbable mini plate had better effect.</p><p><b>CONCLUSION</b>The internal rigid fixation is an appropriate and effective method for the mandible fractures.</p>
