Objective To describe the public discrimination against patients with mental disorders,and to explore its influencing factors.Methods This study was a descriptive study.A total of 1 378 public received the survey.The survey instruments include general information questionnaire and assessment scale of discrimination against patients with mental disorders.Results The scores of the scale of discrimination against patients with mental disorders was (2.07± 0.61).The score of risk dimension was higher(2.17±0.87),and the ability dimension was lower(1.65±0.64).Multiple regression analysis showed that factors influencing the total score of the scale were type of investigation objects,age,gender,educational background,contact degree and life connection degree to the patients with mental disorders.Conclusion Because psychiatric patients had perceived stigma,and social demographic factors,clinical factors,social and psychological factors could influence their perceived stigma,so the nurse should pay more attention to discrimination against patients,and reduce or eliminate the discrimination toward the patients,then promote recovery of the patients.

We developed a rehabilitation system by using the virtual reality technique and the Kinect in this paper. The system combines rehabilitation training with HMI and serious game organically, and provides a game and motion database to meet different patients' demands. Extended interface of game database is provided in two ways: personalized games can be developed by Virtools and Flash games which are suitable for patients' rehabilitation can be download from the Internet directly. In addition, the system provides patients with flexible interaction and easy control mode, and also presents real time data recording. An objective and subjective evaluation method is proposed to review the effectiveness of the rehabilitation training. According to the results of short questionnaires and the evaluation results of patients' rehabilitation training, the system compared with traditional rehabilitation can record and analyze the training data, which is useful to make rehabilitation plans. More entertainment and lower cost will increase patients' motivation, which helps to increase the rehabilitation effectiveness.

Purpose To study the differences of shear wave elasticity and the content of collagen fiber between benign breast lesions and malignant breast lesions, and to analyze the correlation between shear wave elasticity and the content of collagen fiber. Materials and Methods 106 patients with 116 breast lesions who were referred to PLA General Hospital for ultrasound-guided biopsy or surgery underwent shear wave elasticity examination, the biopsy specimen underwent Van Gieson (VG) dye and Image-Pro Plus 5.1 software was used to quantitatively analyze the content of collagen fiber. Results Malignant lesions exhibited signiifcantly higher max elasticity, mean elasticity, and elasticity ratio between lesions and surrounding parenchyma (140.43±70.16) kPa, (63.11±33.68) kPa, 3.49±1.95 than benign lesions (54.64±48.53) kPa, (34.52±25.23) kPa, 2.25±1.48 (t=5.329, 4.382 and 4.487, P<0.01). The content of collagen fiber of malignant lesions was signiifcantly higher than that of benign lesions (t=8.437, P<0.01). There was a positive correlation between max elasticity and the content of ifber collagen (r=0.746, P<0.05). Conclusion The elasticity of breast lesions has a close correlation with the content of collagen ifber, and collagen ifber might play an important role in the development of breast carcinoma.

Objective To analyze the morbidity of the old people with hypertension and metabolic syndrome (MS),the characteristics of MS components distribution,and correlation hypertension and MS.Methods 438 old patients over 60 with hypertension were selected randomly from cheek-up crowd in the physical examination center of Affiliated Zhongshan Hospital of Dalian University in 2013.Abdominal girth,height,body mass were measured,and then calculated BMI.The indicators such as FPG,TC,TG,HDL-C,LDL-C were detected and analyzed.Results The total morbidity of MS in the old people with hypertension was 37.7％,39.0％ from male people,36.7％ from female people,and there was no difference between genders(x2 =0.46,P ＞ 0.05).The level of BMI,abdominal girth,FPG,and TG in the old people with MS were higher than the people without MS(t =4.83,8.53,5.08,7.29,all P ＜0.05),and HDL-C was lower than the people without MS(t =-9.67,P ＜ 0.05).The level of FPG in women was higher than that in men apparently(x2 =5.82,P ＜ 0.05),and the level of HDL-C was lower than that in men apparently (x2 =8.73,P ＜ 0.01).The risk factors to MS include BMI,abdominal girth,FPG,TG (OR =2.139,1.106,2.156,2.315,all P ＜0.05),and HDL-C is protective factor to MS(OR =0.039,P ＜0.05).Conclusion Hypertension might increase MS morbidity of old patients.Hypertension related with MS closely.The risk factors include BMI,abdominal girth,FPG,TG,on the other hand HDL-C is protective factor to MS.

Objective To evaluate the relationship between the grey scale ultrasonographic feature and estrogen receptor(ER),progesterone receptor(PR)or human epidermal growth factor receptor-2(HER-2)expression in infiltrating ductal cancer(IDC)of breast.Methods Seventy-three patients with IDC confirmed pathologically were involved in this study.The specimens wete examined immunohistochemistically to judge the expression of the related factors.ER,PR and HER-2 expression of the mastectomy specimens were determined with immunohistochemical staining technique.The correlation between the ultrasonographic features and ER,PR or HER-2 positive expression was analyzed.

BACKGROUND: As unspecific antagonist of opiate receptor, naloxone is widely used for multiple diseases which are related with abnormal release of endogenous opium. At present, researches suggest that large dosage of naloxone is used at early period can decrease death rate of patients with acute craniocerebral injury and promote neural functional recovery.OBJECTIVE: To investigate the effect of naloxone on improving the nervous function of rats with acute craniocerebral injury and to analyze effectively.DESIGN: Randomized grouping design based on the experimental animal.SETTING: Beijing Neurosurgical Institute.MATERIALS: Totally 250 SD rats were divided randomly into 0.3, 1.0,3.0, 9.0 mg/kg naloxone group, positive control group and negative control group.METHODS: Craniocerebral injured model was established with Feenly free fall struck, and the medicine was given 30 minutes after injury. The rats of the first four experimental group were injected transpeniponeally with naloxone hydrochloride by 0.3 mg/kg, 1.0 mg/kg, 3.0 mg/kg and 9.0 mg/kg respectively once a day; meanwhile, the control groups were given 2 mg citicoline sodium for injection and 0.5 mL normal saline per rat respectively. The longest time was 14 days.MAIN OUTCOME MEASURES: MNSS neural functional score was used every day. The brain edemas of 8 rats in each group were measured with wet-dry weight methods on the second and the fourth day after head trauma.RESULTS: Among 250 rats, 172 entered the final analysis. The nervous function of rats in naloxone groups was better than the two control groups (P ＜ 0.01), and that in 1, 3 and 9 mg/kg naloxone group were better than 0.3 mg/kg group (P ＜ 0.05), but there were no significant differences a mong the three naloxone groups (P ＞ 0.05). The brain edemas of rats in naloxone groups were lighter than that in the control groups (P ＜ 0.05), and that of 1, 3 and 9 mg/kg groups were lighter than 0.3 mg/kg (P ＜ 0.05), but there were no significant differences among these three groups (P ＞ 0.05).CONCLUSION: Naloxone can decrease the brain edemas of rats with traumatic brain injury, promote the nervous function recovery, and the treatment effect changes with the dosage during some range.Therefore, the experiment illustrates that naloxone can decrease the brain edemas of experimental brain injury in SD rats and improve the nervous function, but the effect of naloxone is associated with the dosages in some range.

Objective To study the clonal heterogeneity in differentiation potential of immortalized mesenchymal stem cells in vitro and in rive.Methods The monoclonal cell lines were performed with limiting dilution cloning,and were induced to adipocytic,asteogenic and neuronal differentiation in vitro.After transplanted the monoclonal cell lines into SCID mice,the xenotransplants were removed and evaluated by immunohistochemistry.Results From the parental HMSC-TERT,32 single-cell derived clones were established,of which the differentiation properties varied considerably in vitro.The cells grow in different plating densities during expansion in culture:HMSC-TERT-2 expressed more strongly in LCA,GFAP and vimemin;HMSC-TERT-C19 expressed more strongly in keratinose than HMSC-TERT-2,HMSC-IERT-20,and MSC-H;HMSC-TERT-C2 expressed more strongly in actin than HMSC-TERT-2.Conclusions The HMSC-TERT monoclone cells are heterogeneity in differentiation petential in vitro and in vivo,suggesting that standard in vitro culture and in vivo inoculate procedure phy an important role in the clinical application of stem cells.
