Proteins extracted from two varieties of Chinese roses leaves were separated by two- dimensional polyacrylamide gel electrophoresis (2-DE) with immobilized pH gradient (IPG). Many difference proteins were isolated with molecular weights ranging 10-30 kDa and pI5-6. Three proteins of high levels observed in a gel were excised and identified using peptide mass fingerprinting and MS-MS. A summary of the identified proteins and their putative functions are presented. They are identified as eIF-5A、LEA protein and Hsp17. 5. Functions of these proteins in plant tolerance to high temperature were discussed.

Objective To investigate the clinical curative effect of absorbable screw in the treatment of Limbs joint fracture. Methods From May 2009 to May 2011, 86 patients of Limbs joint fracture in our hospital were randomly divided into the observation group and the control group. The observation group were treated with absorbable screw while the control group were given conventional treatment methods of fracture treatment, and the clinical effect of the two groups were observed after treatment. Results The excellent rate was 56. 3% in control group and 96. 3% in observation group. The excellent rate of the clinical treatment in the observation group was significantly better than the control group with a statistically significant difference (P<0. 05). Conclusion The clinical efficacy of absorbable screw for limbs joint frac-ture is significant, and its operation safety is higher. It improves the life quality of patients and it is worth of clinical promotion.

Objective To compare the biochemical and clinical features of antimitochondrial antibody (AMA) positive and negative primary biliary cirrhosis (PBC),and to compare the sensitivity of both the detection of M2 antibody using enzyme linked immunosobent assay (ELISA) with antigen expressed from human sources,and the detection of AMA using conventional indrect immunofluorecence for diagnosing PBC.Methods AMA and M2 antibodies were tested in 63 patients with diagnosed PBC.Results Serum AMA positive rate in PBC patients was 81%(51/63) compared with 100%(63/63) of M2 positive rate.Antinuclear and anti smooth muscle antibodies(ANA and ASMA) were more frequently positive in the AMA negative patients (83% vs 35%,and 42% vs 4%, P

Objective To investigate the therapeutic efficacy of transcatheter arterial embolization (TAE) in treating advanced bladder cancer. Methods A total of 22 patients with advanced bladder cancer were included in this study. The clinical data and the imaging materials were retrospectively analyzed. The clinical efficacy of TAE in treating advanced bladder cancer was evaluated. Results TAE was successfully accomplished in all the 22 patients. The preoperative and the postoperative abdominal pain scores were 4.73± 1.91 and 2.45±1.29 respectively, the difference was statistically significant (P<0.01); the preoperative and the postoperative ECOG scores were 3.14±0.47 and 2.68±0.56 respectively (P<0.05); the preoperative and the postoperative hemoglobin levels were (61.4±11.8) g/L and (79.3±14.5) g/L respectively (P<0.01). Of 7 patients with urinary tract obstruction, after the treatment the obstruction disappeared in 5 and was improved in 2, although the urination was still not smooth. All patients were followed up for (7.1±3.0) months. The 6-month survival rate was 54.5% (12/22). No serious complications occurred in all patients. Conclusion TAE can not only effectively improve the hematuria and urinary tract obstruction symptoms caused by bladder cancer, but also effectively control the tumor growth, improve the quality of life and prolong the survival time as well.

Objective To compare the functional and radiographic outcomes of modified dual plating and less invasive stabilization system(LISS)in treatment of patients with complex tibial plateau fractures.Methods From November 2003 to November 2004,84 patients with complex tibial plateau fracture were treated with modified dual plating or LISS fixation.Their functional and radiographic outcomes were reviewed to compare the differences in bone union time,full weight-bearing time,knee joint's HSS(The Hospital for Special Surgery)scores,complications, tibia plateau angle(TPA)and posterior slope angle(PA).Results The 84 cases had complete follow-up records and a mean tollow-up of 16.2 months(range,12 to 23 months).Nine complications occurred in the modified dual plating group.The mean full weight-bearing time and radiographic bone union time were 16.8 and 15.1 weeks respectively for this group which had a mean HSS score of 87.4 points.Six complications were found in the LISS group.The mean full weight-bearing time and radiographic bone union time were 14.1 and 13.8 weeks respectively for this group which had a mean HSS score of 89.6 points.There were no significant differences between the two groups in changes of TPA and PA.Conclusion LISS can provide as good fixation as modified dual plating can for most complex tibial plateau fractures,but additional medial plate fixation may be necessary for some special cases.

Objective:To explore the methods to improve the professional core competencies of medical students in the standardized residency training.Methods:A total of 82 medical students who participated in the standardized residency training ("resident students" for short) in the same period were selected in this study, and the self-edited professional core competencies textbooks were used for regular theoretical study, and at the same time, clinical practice cases were collected for regular scenario reduction teaching. When the resident students entered the department and after 12 months of the standardized training, the professional core competencies training evaluation scale was used to evaluate and compare the scores of the resident students, and the value of the above-mentioned training model to improve the professional core competencies of the resident students was evaluated. SPSS 18.5 was performed for t test between groups. Results:After being trained by the above model, the selected students had significantly improved such competencies as communication, cooperation and problems solving ( P<0.05). Compared with the scores of resident students before and after the training, there was no significant difference in communication and cooperation with other students ( P>0.05), with low satisfactory communication with the leader ( P>0.05), but the problem-solving ability had been significantly improved ( P<0.05), while the score of which was low and it should be pay more attention to in the future training. Conclusion:In the process of standardized residency training, the application of the above-mentioned training model can significantly improve the professional core competencies of resident students, and at the same time, it's necessary to strengthen the cultivation of satisfactory communication with leaders and problem solving ability.

Objective:To discuss the computed tomography (CT) and magnetic resonance (MR) imaging features of primary adrenal cortical carcinoma (PACC) and improve the imaging diagnostic level of primary adrenocortical carcinoma.Methods:The imaging features of 15 patients with biopsy or pathology confirmed PACC were retrospectively analiezed. There were 12 patients underwent CT examination, 7 patients underwent MR examination, and 4 patients underwent CT and MR exminations.Results:All of 15 PACCs were unilateral (10 on the right, 5 on the left). The maximum diameters of the lesions ranged from 4.4 to 15.1 (8.9±3.3)cm. The shape of the tumor was oval in 6 cases and irregular in 9 cases. CT findings: 1 cases showed homogeneous density and 11 cases were heterogeneous attenuation (including 2 cases with hemorrhage and 1 case with fat) on plain scan. The CT values of triple-phase of PACC ranged from 28.8 to 62.0(39.2±8.5)HU, 32.7 to 83.4(52.5±14.4)HU and 43.4 to 86.4(61.1±15.0)HU respectively. All cases showed mild (7 cases) and moderate (4 cases) gradual enhancement, only one case excluded. MRI findings: inhomogeneous mild and moderate enhancement were detected in 6 cases and homogeneneous enhancement was found in 1 case. The solid parts of PACC showed iso-signal intensity in T1WI, hyper-signal intensity in T2WI and diffusion limited in the diffusion weighted imaging (DWI). There were 14 cases of vascular shadow in 15 patients, and 3 cases of involvement and metastasis of surrounding tissues and organs.Conclusions:PACC often present as a big solitary heterogenous mass with necrotic area, hemorrhage and intratumoral vascular. The mild to moderate heterogenous gradual enhancement can be seen after the contrast.

Because of the population aging,the increase of the stroke patients and the need for rehabilitation,the treatment only in the rehabilitation department of the hospital is far from the satisfaction of people's demands of the service of rehabilitation.It is important to extend the community-based rehabilitation.Compared with the rehabilitation in hospitals,it is more economy,efficiency and convenience for stroke patients in community-based rehabilitation services,and further improve the rehabilitation effect of stroke patients.

OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.

In order to study event-related desynchronization (ERD) related to voluntary movement, we designed two experiments. In the first experiment, untrained subjects were required to imagine the action of typing with left or right index finger for about 1 second before real action, whereas they were required to type instantly after instruction in the second experiment. By analyzing spontaneous EEG signals between the instruction and the action, we predicted which finger was used. The prediction accuracy in the first experiment fell from 85% to 71% with the progress of experiment, the average accuracy being 78%, whereas the prediction result was almost random guess in the second experiment. The results demonstrate that (1) ERD patterns are significantly affected by the effective duration of motion imagination, (2) unconscious reduction of this duration can decrease the prediction accuracy. Therefore, when designing subsequent BCI experiments, we should devote our attention to the question of how to keep the effective duration of motion imagination.
