Effects of different drying methods including sun drying, steamed, boiled, constant temperature drying (at 40, 50, 60 °C) on appearance, hardness, rehydration ratio, dry rate, moisture, total ash, extractive and polysaccharides contents were studied to provide the basis of standard processing method for Tulipa edulis bulbus. The results showed that the treatments of sun drying and 40 °C drying showed higher rehydration ratios, but lower dry rate, higher hardness, worse color, longer time and obvious distortion and shrinkage in comparison with other drying methods. The treatments of 60 °C constant temperature drying resulted in shorter drying time, lower water and higher polysaccharides content. Drying time is shorter and appearance quality is better in the treatment of steaming and boiling compared with other treatments, but the content of extractive and polysaccharides decreased significantly. The treatments of 50 °C constant temperature drying led to similar appearance quality of bulb to commercial bulb, and it resulted in lowest hardness and highest dry rate as well as higher rehydration ratio, extractive and polysaccharides content, moderate moisture and total ash contents among these treatments. Based on the results obtained, 50 °C constant temperature drying is the better way for the processing of T. edulis bulbus.

OBJECTIVETo evaluate clinical outcomes of fixation for the treatment of radial head fracture with collapse of anterior articular surface.
METHODSFrom March 2006 to January 2013,17 patients with radial head fractures with collapse of anterior articular surface were analysed. According to the Mason classification, there were 12 cases with Mason type II fractures and 5 cases with Mason type III fractures. All the patients were treated with open reduction through posterolateral entrance of elbow joint and Herbert or titanium cannulated screw internal fixation.
RESULTSAll the patients were followed up, and the duration ranged from 6 to 18 months, with a mean of 11.3 months. According to the Broberg and Morrey score system, 2 patients got an excellent result, 12 good and 3 fair. There were no complications such as infection of elbow joint, nerve injury, non-union, traumatic osteoarthritis, heterotopic ossification and elbow instability. However, the postoperative activity range of elbow in the injuried side was less than that in the normal side.
CONCLUSIONRadial head fracture with collapse of anterior articular surface is easily misdiagnosed, and it can be treated with open reduction and internal fixation through posterolateral entrance.

Objective To analyze the monitoring results of human and animal plague in Zhangye city from 1982 to 2011,and further explore the prevention and control policies and measures to control the spread of the disease.Methods The trends of human and animal plague were studied by retrospective survey in Zhangye city.Information of animal and human plague epidemic and prevention and control measures were collcoted and assessed with epidemiology methods,and the density of rodents,the rodents infected with flea,flea index and other indicators were calculated.Results 1982-2011,there were 6 cases of human plague incidence of 6 cases,of which 2 cases cured,4 cases died,the mortality rate was 67%; detection of Yersinia pestis from the captured 5167 animals was 93 strains from 1982 to 2011,the detection rate was 1.80%; 29 840 various vector insects were collected from the body surface of the 5167 animals captured,21 206 hole dries,and three marmot dens.A total of 7050 groups of Marmota parasites and hole stem fleas were inspected,52 strains of Yersinia pestis were isolated,and the average detection rate was 0.74%; 3912 marmot serums were detected,178 were positive,and the positive rate was 4.55%.Conclusions The prevention and control of plague is still very grim in Zhangye city.It is recommended to take publicity,education and active surveillance measures in the future to deal with emergencies and other.

The study was conducted to explore the response of growth and yield of Tulipa edulis to flower bud removal and artificial pollination. And flower bud removal and artificial pollination were carried out in the squaring period and bloom stage respectively. The morphological index and biomass indicators were determined and the yield was counted in harvest time. Result showed that flower bud removal was beneficial to the growth of T. edulis, resulting in increasing growth index, biomass as well as the yield of bulb. The diameter and dry weight of T. edulis fruit by artificial pollination were increased significantly compared with the control. Seed setting percentage increased to 100%, and the number of seed as well as the single grain weight increased by 69.03% and 16.48%, respectively, which did not significantly affect the bulb production. In conclusion, Flower bud removal treatment accelerates bulb biomass increase, so as to improve its yield. Artificial pollination raised significantly seed setting percentage, seed number as well as the single grain weight.

The effect of low temperature storage on dormancy breaking, sprouting and growth after planting of Tulipa edulis was studied. The results showed that starch content and activity of amylases significantly decreased during 10 weeks of cold storage, soluble protein content raised at first then decreased, and the peak appeared at the 6th week. However, total soluble sugar content which in- creased slowly at first than rose sharply and reducing sugar content increased during the storage duration. The bulbs with cold storage treatment rooted in the 6th week, which was about 2 weeks earlier than room temperature storage, but there were less new roots in the late period of storage. After stored at a low temperature, bud lengths were longer than that with room temperature treatment. Cold storage treatment could promote earlier emergence, shorten germination time, prolong growth period and improve the yield of bulb, but rarely affect the emergence rate. It was not beneficial to flowering and fruiting. The results indicated that 6-8 weeks of cold storage was deemed to be the key period of dormancy breaking preliminary.

OBJECTIVETo investigate the diagnosis and treatment of the coronal fracture of the femoral condyle.
METHODSSeven patients with Hoffa fracture treated in our hospital in recent 7 years were enrolled in this study. Six patients were treated with surgical treatment, while one non-displaced fracture received conservative treatment. Fractures were reduced under direct vision and fixed with hollow lag screws. The knees were immobilized in extension with cast after operation, and flexion exercise was commenced 3 weeks later.
RESULTSAll the patients were followed up. According to Kumar functional assessment system,5 patients got excellent results, 1 good, and 1 fair.
CONCLUSIONRigid internal fixation with hollow lag screw and extension plaster fixation is the excellent way to treat the coronal fracture of the femoral condyle.

OBJECTIVETo compare clinical effects between plaster fixation and cannulated screw for the treatment of Jones fracture.
METHODSFrom 2006 to 2010, 41 patients with Jones fractures were divided into 2 groups. In Group A, there were 14 males and 8 females, ranging in age from 21 to 62 years, with an average of (32.3 +/- 8.7) years; the course of disease ranged from 2 h to 3 d; the patients in Group A were treated with plaster fixation. In Group B, there were 9 males and 10 females, ranging in age from 24 to 59 years, with an average of (28.8 +/- 7.9) years; the course of disease ranged from 0.5 h to 2 d; the patients in Group B were treated with cannulated screw fixation. The patients in two groups were followed up from a long time and the long-term effects were studied.
RESULTSAll the 41 patients were followed up, from 3 months to 2.5 years, with a mean of 11.3 months. All the patients in both groups were healed. The patients in Group B got postoperative wound healing with A degree at the first stage without complications. In accordance with the Maryland Foot Score, the therapeutic effect in Group B was better than that of Group A. The healing time in Group B was shorter than that of Group A.
CONCLUSIONPercutaneous minimally invasive treatment with micro-cannulated screw is an ideal method for the treatment of the Jones fracture.
