Response surface analysis (uniform precision of central composite design, SAS 9.1.3 software) was applied to optimize the four major factors (ratio of soybean meal to water, enzyme quantity, fermentation time and inoculation quantity) for soybean meal solid fermentation. According to the change of the hydrolyzation degree of soybean protein, the equation of polynomial regression was established between those factors and the response. The result showed that the optimum condition included as follows: ratio of soybean meal to water 1∶1.00,enzyme quantity 2.55%, fermentation time 65h and inoculation quantity 1.00%. Under the optimum level, the degree of hydrolyzation reached 13.3%, which increased 56% over pre-optimization.

Objective To develop a computer-aided diagnosis(CAD)system with automatic contouring and morphologic and tex-tural analysis to aid on the classification of breast nodules on ultrasound images .Methods A modified Level Set method was pro-posed to automatically segment the breast nodules(46 malignant and 60 benign nodules) .Following ,16 morphologic features and 17 texture features from the extracted contour were calculated and principal component analysis(PCA)was applied to find the optimal feature vector dimensions .Fuzzy C-means classifier was utilized to identify the breast nodule as benign or malignant with selected principal vectors .Results The performance of morphologic features was 78 .30% for accuracy ,67 .39% for sensitivity and 86 .67%for specificity ,while the latter was 72 .64% ,58 .70% and 83 .33% ,respectively .After the combination of the two features ,the re-sult was exactly the same with the morphologic performance .Conclusion This system performs well in classifying the malignant breast nodule from the benign breast nodule .

Objective To study the clinical value of rapid prototyping oriented template for total hip replacement in patients with adult developmental dysplasia of the hip .Methods Totally 51 cases with adult developmental dysplasia of the hip who were admitted into our hos -pital from January 2014 to March 2015 were randomly divided into the observation group and the control group .The observation group were treated by total hip arthroplasty assisted with rapid prototyping oriented template , while the control group were treated with traditional surgical method for total hip replacement.The curative effect, operation time, amount of bleeding, hospitalization time and satisfaction rate were compared between the two groups .Results The operation time , intraoperative blood loss and length of hospital stay of the observation group were significantly lower than those in the control group , and the differences were statistically significant (P<0.01).The Harris hip function score and satisfaction rate of the observation group were significantly higher than those in the control group with statistically significant differ -ences (P<0.05).Conclusion Total hip arthroplasty assisted with rapid prototyping oriented template could shorten the operation time , re-duce the intraoperative blood loss , cut down the hospitalization time , quicken the hip joint function recovery , and improve the satisfaction rate of patients .

AIM: To investigate the clinical effects of intravitreal Bevacizumab for 26 cases with retinopathy of prematurity (ROP) in Zone Ⅰ.
METHODS:A retrospective study. Totally 26 ROP infants between September 2013 and October 2014 diagnosed as high - risk ROP in Zone Ⅰ had been treated with intravitreal bevacizumab. They were divided into three groups, pre - threshold ROP, threshold ROP and acute posterior ROP ( APROP ). Postoperative effects were compared.
RESULTS:There were 26 infants (52 eyes) diagnosed as ROP in Zone Ⅰ, including 3 infants( 6 eyes) with pre -threshold ROP, 15 infants (30 eyes) with threshold ROP and 8 infants (16 eyes) with APROP. The first operation recovery rate of three groups respectively were 100% (6 /6), 60% ( 18 / 30 ) and 75% ( 12 / 16 ), which were not significantly different (P>0. 05).
CONCLUSION:Intravitreal bevacizumab for ROP in ZoneⅠ seems effective and has some advantages over conventional laser treatment, which could be first line treatment for high-risk ROP in Zone Ⅰ.

ObjectiveTo investigate the intelligence characteristics and relativity with motor development of children with spastic diplegia.MethodsIntelligence and motor development of 46 children with spastic diplegia were tested by Wechsler Intelligence Scale and Motor Development Milestone (MDM), to find out difference of intelligence between the children with diplegia and the normal control group.ResultsIntelligence quotient (IQ) of children with spastic diplegia was lower significantly than the normal control, specially performance IQ (PIQ). PIQ was related with motor development. The more delayed motor development was, the more lower PIQ was. Subtest scores of animal egg, puzzle, block design and picture generalization were lower in spastic diplegic children with normal IQ than that of the normal control group, while vocabulary IQ (VIQ) was not different.ConclusionThe intelligence structure of children with spastic diplegia is imbalanced and PIQ of those children is significantly lower than the normal children, which is related to hands-eyes correspond, sight-motor correspond and speed, and space-sight ability.

In all the carpal fractures, scaphoid fracture is the most common in clinic (from 60% to 70% in proportion) and likely leads to nonunion. If nonunion is not treated in time, it probably causes instability of the scaphoid lunate joint, further leading to scapholunate advanced collapse. Its comprehensive manifestations include degenerative arthropathy of radial styloid process, radial scaphoid joint, capitulolunate joint and even total wrist joint, eventually leading to wrist joint dysfunction. Therefore, more and more attention has been paid to treatments of scaphoid fracture nonunion. Bone grafting is the most common practical treatment, but new surgical procedures have emerged in recent years. This article thus reviews the research advances in bone grafting for scaphoid fracture nonunion, commenting on the advantages and disadvantages of various techniques.

Objective T o evaluate the application value for the prognosis of m echanical ocular injury cases using ocular traum a score (O TS). Methods Four hundred and eleven cases of m echanical ocular traum a w ere retrospectively review ed. O f the 449 eyes, there w ere 317 closed globe injury and 132 open globe injury. O T S variables included num erical values as initial visual acuity, rupture, endophthalm itis, perforat-ing or penetrating injury, retinal detachm ent and relative afferent pupillary block. T he differences be-tw een the distribution of the final visual acuity and the probability of standard final visual acuity w ere com pared to analyze the correlation betw een O T S category and final visual acuity. T he different types of ocular traum a w ere com pared. Results C om pared w ith the distribution of final visual acuity in standard O T S score, the ratio in O T S-3 category w as statistically different in present study, and no differences w ere found in other categories. Final visual acuity show ed a great linear correlation w ith O T S category (r=0.71) and total score (r=0.73). C om pared w ith closed globe injury, open globe injury w as generally associated w ith low er total score and poorer prognosis. R upture injury had poorer prognosis com pared w ith penetrating injury. Conclusion T he use of O T S for the patients w ith ocular traum a can provide re-liable inform ation for the evaluation of prognosis in forensic m edicine.
