Objectives To compare the efficiency and clearance of single dose low molecular weight heparin(LMWH) as anticoagulant in hemodiafiltration and hemodialysis.Methods Twenty-two patients were enrolled in the study.A single injection of LMWH(Nadroparin calcium 7500ICUAXa) was given before hemodiafiltration and hemodialysis respectively.The anti-factor-Xa activity and the activated partial thromboplastin time(APTT) in plasma were assayed during the treatment,and the dialyzer coagulation was observed.The changes of urea and serum creatinine were measured before and after the treatment.Results The anti-factor-Xa activity of LMWH during hemodiafiltration was lower than that during hemodialysis.However,there was no significant difference in APTT between the two groups.Conclusions A single bolus injection of Nadroparin provides a simple and effective anticoagulation regimen for hemodiafiltration lasting up to four hours.

Object To optimize the process for the extraction of the original recipe used in the treatment of eczema to give a new ECZEMA SPRAY dosage form Methods The extraction process was studied by orthogonal experimental design as guided by determining the content of paeonol and baicalin in the extract Results The optimal extraction process was to reflux the original recipe with 80% ethanol twice at a bath temperature of about 90 ℃ for 1 5 and 1 0 h respectively The amount of ethanol used for each extraction was 10 and 8 times of the original recipe respectively Conclusion The above extraction process gave the most rational and satisfactory results

This paper proposed a rehabilitation training system with electromyography (sEMG) feedback for stroke patients based on ARM embedded system and LabVIEW. The system can achieve real-time acquisition, processing and dualview of multi-channel sEMGs and compute related sEMG parameters including iEMG, RMS, MPF and co-contraction ratio. The system was detected by clinical experiments and related inspection department. The result showed that the system is functional, interactive and in accordance with the relevant standards for medical devices so that it can fully satisfy the clinical demands. In addition, the system can help doctors to master the training state of the patient more effectively in a real-time and quantitative way that is direct to improve the training programs of stroke patients.

Objective To investigate clinicopathologic characteristics of obsolete Bennett fractures and their surgical treatment and prognosis. Methods From August 2008 to April 2010,13 patients with obsolete Bennett fracture were admitted to our department.They were 12 men and one woman,with an average age of 34.3 years (from 17 to 42 years).They had a fracture history of over 4 weeks to as long as 12 weeks (average,7.9 weeks).In all patients,after X-ray examinations,the radio-dorsal ligament complex of the first carpometacarpal joint was properly released,fracture gaps were cleared up,fracture fragments were anatomically reduced and fixed with a Kirschner wire,and at last the first metacarpal joint was fixed with the Kirschner wire crossing the joint Postoperatively all patients were immobilized with cast plaster for 4 weeks before the Kirschner wires acrross the joint were removed.Gradual rehabilitation was conducted.The X-rays were taken every month. Results The patients were followed for 6 to 24 months(average,14 months).The fractures healed in all the patients,with an average healing time of 3 months.No dislocation of the joints occurred.Injury to articular cartilage of the trapezium bone occurred in one patient,and no apparent pain was experienced in the other 12 patients.According to the Total Active Motion assessment,the thumb function was rated as excellent in 9 cases,good in 2,moderate in one and poor in one,with a good to excellent rate of 84.6%.Conclusions In obsolete Bennett fractures,the radio-dorsal ligament complex of the first carpometacarpal joint will have cicatricial contracture,preventing reduction of the fragments of the radio-dorsal joint.Therefore it is important to properly release the radio-dorsal ligament complex to achieve anatomical reduction of the radio-dorsal joint.An injury history of over 3 months and complicated injury to the trapezium bone cartilage may be significant factors affecting the prognosis of obsolete Bennett factures.

Objective To compare the effect of compression hollow screw fixation,artificial femoral head replacement and total hip replacement in the elderly.Methods From August 2007 to April 2009,152 cases of femoral neck fracture in the elderly were divided into three groups: compression hollow screw fixation group(54 patients,24 males,with an average age of 59.8±5.3 years);artificial femoral head replacement group(48 patients,16 males,with an average age of 65.3±6.7 years);and total hip replacement group(50 patients,18 males,with an average age of 77.3±6.5 years).The evaluation indicators,including the average sugical time,the average amount of bleeding,the average length of stay and the average postopererative bed time,were compared respectively among the three groups.The postoperative evaluation was made according to Harris Score.Results Harris score in the three groups were 21 excellent and 23 good in the compression hollow screw fixation group,with an average score of 80.52±2.70;26 excellent and 14 good in the artificial femoral head replacement group,with an average score of 86.57±1.90;and 42 excellent and 3 good in the total hip replacement group,with an average score of 96.04±2.10.The total hip replacement group was significantly better than the other two groups(H=0.589,F=12.151,Ps<0.05).The rate of postoperative complications were 25.93%(14/54) in the compression hollow screw fixation group,18.75%(9/48) in the artificial femoral head replacement group and 4.00%(2/50) in the total hip replacement group(H=1.291,P<0.05).Conclusion Compared among the three surgery,total hip replacement could resume function and improve the quality of life better,with lower rate of complications.However,the surgical injury and the amount of bleeding were largest.Therefore,we suggest selecting appropriate surgery with considering the patient′s age,physical condition,displacement degree of the fracture,et al.in old femoral neck fractures patients.

BACKGROUND: Type Ⅰ collagen is a specific collagen secreted by in vitro cultured osteoblast, and the formed network is the basis of bone mineralization, which also reflects the ability of osteoblast bone formation. Studies have shown astragalus root increased osteoblast proliferation. However, the effect of astragalus root on improving type Ⅰ collagen expression of osteoblast remains poorly understood.OBJECTIVE: To evaluate the effect of astragalus root injection on the abilities of rat cranium-derived osteoblast proliferation and type Ⅰ collagen expression.METHODS: Rat osteoblast was cultured in vitro and divided into control group (MEM culture solution containing calf serum) and astragalus root groups (different concentrations). The effect on osteoblast proliferation was evaluated on days 1, 3, 5, 7, and 9 by MTT method. Moreover, the expression of type Ⅰ collagen protein was observed after 6 hours of treatment with astragalus root injection using in cell western-blot method. In addition, the gene expression of COLLal was investigated by real-time PCR method.RESULTS AND CONCLUSION: From days 3 to 9, the different concentrations of astragalus root injection improved osteoblast proliferation, respectively compared with control group (P < 0.05), and this ascending trend peaked on day 7. Different concentretions of astragalus root injection improved COLLol mRNA expression, especially 15% astragalus root injection was the most effective. The type Ⅰ collagen protein expression of 15% and 10% astragalus root injection were significantly greater compared with the control group (P < 0.05). Astragalus root injection improved in vitro cultured osteoblast proliferation and type Ⅰ collagen secretion in a certain dose-effect manner.
