A new kind of curcin (curcin 2), induced by several kinds of stresses from Jatropha curcas leaves, under the control of the 35S CaMV (cauliflower mosaic virus) promoter, was introduced into tobacco genome by Agrobacterium tumefaciens-mediated transformation method. Curcin 2 protein was only detected in the transgenic tobacco plants transformed with the cur2p fragment (coding premature curcin 2 protein), but not in the plants transformed with cur2m fragment (coding mature curcin 2 protein). The transgenic lines expressing curcin 2 showed increased tolerance to tobacco mosaic virus (TMV).

Objective To investigate question comprehension and production among agrammatic aphasics, and to explore the mechanisms of any dysfunction in questioning.Methods Twenty aphasics were recruited in this study.According to the Chinese Agrammatism Battery,10 were classified as agrammatic (the agrammatic group) and 10 as non-agrammatic (the non-agrammatic group).Ten normal subjects served as a control group.All the subjects were tested in terms of their comprehension and production of questions using a set of general and what-where-who- why questions (wh-questions).Results No significant difference was found between the two experimental groups with regard to the correct comprehension and production of both general and wh-questions.However,there was a sig- nificant difference in correctness between comprehension and production.The performance of the agrammatic aphasics was worse than that of the non-agramatics and the normal subjects.Conclusion The impaired question comprehen- sion and production of Chinese agrammatic aphasics has its own characteristies which can form a basis for rehabilita- tion planning and outcome prediction.

Background Aheration of eyeball wall caused by ocular axial extension is associated with multiple complications of high myopia.However,the study on quantitative analysis of choroidal thickness and axial length in adult high myopic patients is less.Objective This study was to investigate the choroidal thickness in high myopic eyes of adult patients and estimate the correlation of choroidal thickness with axial length,age,and spherical equivalent(SE).Methods A prospective cohort study was designed.Seventy-five eyes of 75 adult patients with high myopia were entrolled from December 2012 to May 2013,and 70 eyes of 70 age-and gendermatched healthy volunteers were included in Renmin Hospital of Wuhan University.Enhanced depth imaging (EDI)on Cirrus spectral-domain optical coherence tomography (SD-OCT) was used to measure the choroidal thickness from the outer border of the retinal pigment epithelium through the inner scleral boarder among the 11 meridians in a 500 μm intervals and range of 2 500 μm for each from fovea toward temporal and nasal lateral.The differences of choroidal thickness and axial length were compared between the high myopia group and normal control group,and the correlation of choroidal thickness with axial length,age,SE were analyzed.Results The subfoveal and mean choroidal thickness values were (146±52) μm and (142±63) μm in the high myopia group,and those in the normal control group were (306±60) μm and (271 ±71) μm,with significant differences between the two groups (t =-17.130,P=0.000; t=-15.890,P=0.000).Choroid was thickest in the temporal and then was subfovea and nasal in the high myopia group,but in the normal control group,it was subfovea,temporal and nasal in turn,and the choroidal thicknesses in various areas were thinner in the high myopia group than those in the normal control group.A negative correlation was found between the choroidal thickness and axial length in high myopia group(r =-0.580,P =0.000),and the regression equation determined a decrease of 17.943 μm per millimeter of axial length.Conclusions SD-OCT determines that choroidal thickness is decreased in highly myopic eyes compared with normal eyes.Choroidal thickness varies with the change of axial length in adult high myopia patient.These findings indicate that abnormalities of the choroids may play a role in the pathogenesis of complication of high myopia.

BACKGROUND:The hidden blood loss, accounted for a fairly large proportion of perioperative blood loss in total hip replacement, can seriously affect the recovery of postoperative joint function, but the specific influential factors and mechanisms remain unknown at present. OBJECTIVE:To evaluate the relative influential factors for hidden blood loss after primary total hip arthroplasty by the blood loss condition, and to analyze the association between hidden blood loss and prognosis. METHODS:Clinical data of 110 patients who underwent primary total hip arthroplasty in the Liuzhou Worker’s Hospital between April 2011 and April 2013 were retrospectively analyzed. The hidden blood loss was calculated according to Ward and Gross formula. The effects of patient’s gender, age, body mass index, type of prosthesis, presence of internal diseases, and different causes of a disease on hidden blood loss after arthroplasty were analyzed. The patients were divided into the high blood loss group (≥ 480 mL) and the low blood loss group (<480 mL) according to the hidden blood loss. Al the patients were fol owed up for 1 year. The Harris hip score system was used to assess the recovery of hip joint function between the two groups. The correlation between hidden blood loss and the recovery of joint function was analyzed using Pearson’s correlation analysis RESULTS AND CONCLUSION:The total blood loss of primary total hip arthroplasty was (1 340±367) mL, and the hidden blood loss was (748±324) mL, and the percentage of hidden blood loss was 53.7%. The type of prosthesis, presence of internal diseases, and different causes of a disease were significantly associated with hidden blood loss after total hip arthroplasty (P<0.05). Gender, age, body mass index, and operation time were not significantly associated with hidden blood loss after total hip arthroplasty (P>0.05). The hidden blood loss was correlated with postoperative functional recovery (P=0.046). Results indicated that type of prosthesis, presence of internal diseases, and different causes of a disease are main influential factors for hidden blood loss after total hip arthroplasty. The hidden blood loss has some influence on the recovery of postoperative joint function.

Objective To reproduce a scratch-wound model in cultured rat astrocytes (AST).Methods The secondary cultured AST prepared from newborn Wistar rat cerebral cortex were scratched with plastic pipette tips. The morphologic change of AST was observed through microscope at 10 min before and 1, 3, 6, 12, and 24 h after injury, meanwhile the lactate dehydrogenase (LDH) leakages in the cultured medium were determined.Results Immediately after injury the edge of the scratch was lined with irregularly shaped cell. 6 h after injury the AST processes began extending to cell-free area, and elongated further at 12 and 24 h after injury, with presented of new generated cells in the denuded area. At different times after injury, the LDH leakages of the experiment group were higher than that before injury ( P<0.05), and were higher than that of the control group ( P<0.05).Conclusion According to observed AST morphologic changes and determined LDH leakages in culture medium, the scratch-wound model in cultured rat AST is successfully reproduced.

Objective To explore the value of color doppler ultrasonography by bed side in the early diagnosis of HIE in full term neonates.Methods The changes of cerebral parenchymal and cerebral arterial blood stream parameter on 35 cases of neonates clinically diagnosed HIE of mild and moderate degree and 40 cases of normal newborns on the 24,48 and 72 hours after birth were observed by color doppler ultrasonography by bed side.Results 1.The cerebral parenchyma was even echo in normal newborns,but it was maldistributed and reinforced in mild asphyxia neonates and it was more serious in moderate degree.The echo of cerebral parenchyma in mild degree was near normal in 48 hours after birth,while the echo of cerebral parenchyma in moderate degree was still maldistributed and reinforced in 48 and 72 hours after birth.2.There was obvious changes in the cerebral arterial blood stream parameter and hemodynamics of the asphyxia newborns compared with normals.The systolic peak velocity(Vs)and end diastolic velocity(Vd)of the cerebral arteries in mild and moderate degree were obviously lower than that of control group in 24,48 hours after birth(Pa0.05).3.Resistance index(RI)of the cerebral arteries in mild and moderate degree were higher than that of control group in 24,48 hours after birth(Pa0.05).Conclusion Color doppler ultrasonography by bed side is a convenient,noninvasive method for diagnosing HIE.

Objective To explore an economic and effective management strategy for lumbar disc herniation (LDH) in community health center. Methods 62 LDH patients treated in Xujiahui community health center (observation group), 48 LDH patients treated in Huajing community health center (control group A) and 55 LDH patients treated in Shanghai 6th People's Hospital (control group B) were included.The observation group was managed by associate professor from Shanghai 6th People's Hospital and accepted different treatment strategy in mild, medium and heavy grades. The control groups A and B were managed routinely. 3 month later, costs of illness were computed and curative effects were accessed in 3 groups. Results There was no difference in curative effects between observation group and control group B (P>0.05), but better than control group A (P<0.05). The observation group cost the least among the groups (P<0.05). Conclusion Graded treatment strategy united with tertiary hospital is an economic and effective mode for LDH management in community health center.

Objective To evaluate the CT findings and classification of the Le Fort fracture. Methods Sixty-two cases with Le Fort fractures were studied with thin-slice high-resolution CT scanning and analyzed with three-dimensional(3D)imaging reconstruction.Results Of the 62 patients,10 had Le Fort type Ⅰ fracture,9 had Le Fort type Ⅱ fracture,8 had Le Fort type Ⅲ fracture,and 35 had various combinations of the three types of Le Fort fractures,including 18 Le Fort Ⅰ+Ⅱ fracture,7 Le Fort Ⅰ+ Ⅱ+Ⅲ fracture and 10 Le Fort Ⅱ+Ⅲ fracture.Fifty-five cases had associated multiple fractures in the maxillofacial region.On 2D CT images,Le Fort fracture manifested as multiple and complex fractures. Though 2D image was better than 3D image in accurately defining tiny fractures and fractures of deep structures,the diagnosis of Le Fort fracture could not be correctly made solely on 2D image.3D CT clearly and stereoscopically demonstrated the entire shape and orientation of Le Fort fracture,thus facilitating the correct classification of Le Fort fracture.Conclusion 3D CT image is important in providing information about the space relationship of Le Fort fracture,thus very valuable for the preoperative planning.
