Objective To adjust the layout of secondary medicine shelves in hospital pharmacy for outpatient services and optimize the varieties of automated equipment to improve working process and promote human-machine cooperation.Methods This article discussed the adjustment of the layout of secondary medicine shelves in hospital pharmacy for outpatient services and the optimization of varieties of automated equipment for storing by analyzing actual problems in automated system and clinical drug uses and the requirements of the automated equipment for drug storage respectively to improve working process and to adapt to the operation of outpatient pharmacy automated system.Results Dispensing efficiency of outpatient pharmacy automated system was improved, patients′ waiting time was significantly shortened, and the workload of pharmacists was decreased.Conclusion Optimization of hospital pharmacy drug delivery system and its operation can obviously improve work efficiency, shorten patients′ waiting time and reduce dispensing error, thus ensuring the safety of medication.

OBJECTIVETo observe the effectiveness of percutaneous bone marrow grafting for treatment of fractures nonunion.

METHODSFrom June 2001 to December 2007, 29 consecutive cases of fractures nonunion were treated with percutaneous autologous bone marrow grafting included 20 males and 9 females, ranging in age from 20 to 71 years, with an average of 40 years. All the cases were traumatic fractures involving 13 of tibia, 10 of femur, 3 of humerus, 2 of ulna, 1 of radius, 11 cases of them were open fractures. All the cases were performed internal or external fixation before marrow grafting, intramedullary pin in 15 cases, plate in 12 cases, external fixator in 2 cases. The time from injury to therapy were from 6 to 12 months, with an average of 8.5 months. The type of nonunion included atrophic in 26 cases,hypertrophic in 3 cases. All the cases were performed 3 times injection, the interval was 1 month. According to the different fracture, the amount of bone marrow was from 6 to 15 ml.

RESULTSAll the 29 cases were followed-up for from 5 to 22 months with an average of 14 months. Four of them were not observed obvious callus after 3 months from the 3rd injection, judged unsuccessful therapy, changed to perform autologous bone grafting (3 of them re-internal fixation), the follow-up ended. The other 25 cases obtained bone union during 3 to 8 months with an average of 4.5 months, the follow-up ended at the time of internal fixation removal.

CONCLUSIONPercutaneous autologous bone marrow grafting is an effective, easy and economic therapy for fracture nonunion. But stable internal or external fixation is the premise. Excessive bone defect, the gap more than 5 mm and mal-align requiring rectification is not appropriate for this therapy.

OBJECTIVETo observe the clinical characteristics of triceps brachii tendon rupture at olecranon ending.

METHODSFrom June 2005 to November 2011,19 patients with triceps brachii tendon rupture at olecranon ending were treated with surgical technique. Among the 19 patients, 7 patients were male, with an average age of 24.1 years old (ranged, 15 to 41 years old); 12 patients were female, with an average age of 51.4 years old (ranged, 16 to 73 years old). Eight patients had injuries in the left elbows, and 11 patients had injuries in right elbows. Seventeen patients had injuries induced by walking fall and 2 patients had injuries induced by falling down. Thirteen patients were simple triceps brachii tendon rupture at olecranon ending, 6 patients were associated with other elbow injuries. Five patients were associated with radial fracture; 1 patient with capitellum fracture; 1 patient with coronoid process fracture; 1 patient with epitrochlear. All the lateral radiographs of the injuried elbow demenstrated the flecks of avulsed osseous material from the olecranon (flake sign). The associated injuries had the homologus presence. All the patients were treated with surgical techniques:15 patients were treated with figure-of-eight tension-band wire; figure-of-eight tension band wire and Kirschner wire in 1 patient; wire cerclage in 1 patient; nonabsorbable suture in 2 patients. The associated injuries were treated simultaneously. Plaster was applied after operation in 2 patients with heavier elbow associated injuries, other patients without any external fixation. The Mayo elbow score were observed to determinate the function of the elbow.

RESULTSAll the patients were followed up, 1 patient died of other disease at one year after operation, the other 18 patients were followed up with an average of 47.9 months (ranged from 14 to 91 months). According to the Mayo elbow score, 16 patients got an excellent result and 2 good.

CONCLUSIONTraumatic rupture of triceps brachii tendon at olecranon ending is not a rare injury, which is common in female older than fifty and in male younger then thirty. Surgical results are generally excellent. But dysfunction frequently remains in patients with associated elbow injuries.

The sectional test was adopted in this study to investigate the corrosion of pure iron in 0.15 mol/L NaCl solution, Ringer solution, PBS(-) solution, SBF solution and M199 cell culture medium at three different times. The result shows that different mediums have different corrosion effects on pure iron. The arrangement according to the medium's corrosion ability from the strongest to weakest is 0.15 mol/L NaCl solution (Ringer solution), PBS(-) solution, SBF solution and M199 cell culture medium. The results of scanning electron microscopy and energy dispersive X-ray spectrum analyses show that the addition of HPO4(2-), H2POC4-, Ca2+, Mg2+, SO4(2-) and the organic component can inhibit the corrosion to some degree.
