Objective To explore the correlations between emotions and self-concept in patients with traumatic brain injury. Method The Chinese version of the Positive and Negative Affect Scale and the Tennessee Self-Concept Scale was used to test 178 patients with traumatic brain injury.Results The mean scores on positive and negative emotions were (1.93±0.53) and (2.76±0.61), respectively. The mean score on self-concept was (2.45±0.31). The positive emotions of patients were positively correlated with the level of self-concept and the negative emotions negatively with the level of self-concept (r=0.437and -0.363respectively,bothP<0.01). Conclusions For patients with traumatic brain injury,the negative emotions outnumber the positive emotions and their self-concept was at lower level. Nurses should take measures to improve their positive emotions and reduce their negative emotions in order to improve their self-concept level.

Objective Pressure Ulcer Scale for Healing ( PUSH) was published in 1998 by National Pressure Ulcer Advisory Panel ( NPUAP) as a tool to evaluate the effects of pressure ulcer care.This study aimed to verify the reliability and validity of the Chi-nese version of PUSH in order to provide an efficient and reliable tool for evaluating the effects of pressure ulcer care. Methods Using the Brislin translation model, we translated the English version of PUSH into Chinese and finalized the Chinese version through modifica-tion by an advisory panel, pretests, and verification of its reliability and validity in the care of 126 cases of stage-Ⅱ-Ⅳpressure ulcers. We analyzed the reliability and validity of the scale based on its item scores, content validity, construct validity, Cronbach′s αcoeffi-cient, and test-retest reliability. Results The correlation coefficient value of the total and individual item scores was 0.616-0.963 (P<0.01).Each individual item score was significantly higher in the 27%high-score group (n=35) than in the 27%low-score group (n=36).The total content validity coefficient was 0.965, the correlation coefficient of construct validity between the total and individual item scores was 0.750-0.954 (P<0.01), and that between individual items was 0.666-0.826 (P<0.01), with statistically signifi-cant differences between the total and individual item scores at 7 and 21 days after treatment (P<0.01).The Cronbach′s αreliability coefficient value of the total score was 0.823 and those of individual item scores were 0.770, 0.791, and 0.868, respectively.The inter-rater reliability coefficients were all >0.85 and the test-retest reliabili-ty coefficients of individual items were 0.826, 0.885, and 0.958, re-spectively ( P<0.01) . Conclusion The Chinese version of PUSH, with its high validity and reliability, can be used to evaluate interven-tion effectiveness of Chinese patients with pressure ulcers.

[Summary] To investigate the effect of microRNA126 on glucose metabolism in the normal liver cell lines. In vitro, the chang liver cell lines were cultured. Under the most effective transfection conditions ascertained above, microRNA126 mimic, microRNA126 inhibitor, and relative negative control were transfected into the cultured normal liver cells. And the transfection efficiency was tested by realtime fluorescent quantitative PCR. After 48 hours, the cells were stimulated with synthetic insulin ( 100 nmol/L ) and respective substrates for 2 hours. Then the glycogenesis, gluconeogenesis, and glycolysis in cells were measured. The level of microRNA126 of the microRNA126 mimic group was higher than the other groups, and the difference was statistically significant ( P<0. 05 ). MicroRNA126 mimic group significantly decreased glucose utilization, reduced glycogen synthesis, effectively increased the account of gluconeogenesis, reduced lactate production, and pyruvate kinase activity ( all P<0. 05). The over-expressing microRNA126 in hepatocytes may reverse the function of glucose metabolism, and enhance output of hepatic glucose.

The legal dilemma of informed consent facing in our country does not mean that the Chinese tradi-tional culture and the western human rights thought exist incommensurable. The solution to the informed consent di-lemma still needs take Chinese traditional"ritual" and"law" culture as basis, achieve the integration of ritual and law, eliminate their adverse effects, build the better Chinese medical ethics culture and medical legal culture, and promote the medical ethics, patient' s ethics and construction of legal system return to rational, so as to guarantee the effective realization of the double normative effect of law and ethics of the right and obligation of informed con-sent.

Background The incidence of dry eye is gradually increased,and researches showed that inflammation participated in the pathogenesis and development of dry eye.The current therapy for dry eye can only relieve symptom but not achieve final cure.Stem cell therapy has been used in the treatment of limbal stem cell deficiency.However,whether it is feasible for the stem cell treating dry eye is still unclear.Objective This study attempted to investigate a new approach to treat dry eye syndrom by using human umbilical cord mesenchymal stem cells (HUCMSCs).Methods The use and care of experimental animals complied with the Tsinghua University School of Medicine Laboratory Animal Care Details.HUCMSCs were cultured and cell suspension was prepared with the cell density of 5×105/ml.Twenty 24-week-old male NOD/Ltj mice were randomized into 4 groups.0.1 ml PBSHUCMSCs suspension was injected via tail vein or lacrimal respectively in the caudal vein injection group and lacrimal injection group,and 10 μ1 PBS-HUCMSCs suspension was topically administed in the eye drops group.The NOD/Ltj mice without any treatment served as the model group.Five male ICR mice were used as the normal control group.Tear secretion was quantitatively detected with phenol red cotton thread in 1,2,3 weeks after injection,and corneal epithelial defect was scored by fluorescein staining.The serum levels of interleukin (IL)-6,IL-17a,tumor necrosis factor-α (TNF-αt) and interferon-γ (IFN-γ) were assayed by ELISA.The relative expression levels of p65,Stat3,Stat5 and extracellular signal-regulated kinases (Erk)-1 in lacrimal gland were detected by Western blot.Results The tear secretion amount was significantly different among the model group,caudal vein injection group,lacrimal injection group and eye drops group in various time points (1 week:F =3.700,P =0.040;2 weeks:F =5.150,P =0.008;3 weeks:F=10.130,P＜0.001).The tear secretion amount was increased in the caudal vein injection group and lacrimal injection group compared with the model group in different time points (all at P＜0.05),and no significant difference was seen in tear secretion amount between eye drops group and model group among various time points (all at P＞0.05).The fluorescein staining score was 3.00±0.63,9.40±1.62,5.20±1.17,4.20±1.17 and 7.20±0.98 in the ICR mouse control group,model group,caudal vein injection group,lacrimal injection group and eye drops group 1 week after injection respectively,and the scores were significantly lower in the caudal vein injection group,lacrimal injection group and eye drops group than those in the model group (P =0.001,0.000,0.033).The serum levels of IL-6,IL-17a and TNF-α in the caudal vein injection group were evidently lower than those in the model group (t =4.70,3.46,11.0,all at P＜0.01),but no significant difference was displayed in the serum IFN-γ level among the five groups (F=1.740,P=0.170).The expressions of STAT5 were significantly decreased in the mice treated with tail vein injection and lacrimal injection compared with mice without treatment (both at P＜0.05).Conclusions Administration of HUCMSCs via intravenous and lacrimal injection can alleviate the inflammatory response during progression of dry eye syndrome by down-regulating the serum level and expression of inflammation-related factors in NOD/Ltj mice.The topical administration of HUCMSCs eye drops can attenuate the symptom of dry eyes by lubricating the cornea and suppling nutrition.

In this research was developed high efficiency method using 125I for directly labeling KH901, a tumor-specific oncolytic recombinant adenovirus, biodistribution of 125I-labeled compound in normal mice was investigated. 125I-KH901 was prepared by N-bromosuccinimide labeling method to find the optimal ratio of labeling response. The compounds were isolated and purified by Sephadex-G10 agarose and the radiochemical purity of compounds was analyzed by paper chromatography. The radioactivity biodistribution in mice was measured at different times after caudal vein injection with 0.1ml 125I-KH901. The labeling yield of 125I-KH901 was 78% and the radiochemical purity was 95% after purification by Sephadex-G10 agarose. Biodistribution revealed that the uptake of 125I-KH901 in liver was higher than in other organs at all time points of the experiment. 125I-KH901 was mainly concentrated in liver, kidneys, spleen and lung. It can be seen that N-bromosuccinimide labeling method is an optimal method with simple steps and high labeling yield in labeling KH901 with 125I. 125I-KH901 has a biodistribution trait which is an advantage to treating liver tumors.

BACKGROUND:Percutaneous vertebroplasty and percutaneous kyphoplasty have become the mainstream clinical methods for the treatment of vertebral compression fractures. However, both of them have several shortcomings such as bone cement leakage, spinal stenosis, nerve compression, pulmonary embolism and other issues. OBJECTIVE:To verify the possibility of bone filing mesh container prepared by polyethylene terephthalate for the treatment of vertebral compression fractures. METHODS:The biological properties of bone filing mesh container were examined according to GB/T16886. After sample aging test, the tensile properties of the aged samples and the fresh prepared samples were compared. The expansion and bone cement leakage were evaluated by injecting bone cement into the bone filing mesh container and measuring the pressure. The initial strength and stiffness of the fresh pig vertebrae with calcium phosphate cement injection or with bone filing mesh container filed with calcium phosphate cement were compared. The in vivo bone tissue growth was periodicaly observed after the lumbar vertebra of 4-month-old pigs was implanted with the bone filing mesh container that was then ful of bone cement. RESULTS AND CONCLUSION: The bone filing mesh container had good biocompatibility. Bone filing mesh containers after 2-year storage had the same tensile strength to the fresh bone filing mesh containers. At ambient conditions, after bone cement injection, bone filing mesh containers could be expanded at 5-10 atm and therefore could play the role of uplift; at 7-10 atm, bone cement could leak out from the bone filing mesh container and enter into the interspace between surrounding bone tissues, thus playing the role of adhesion and fixation. The vertebrae after bone cement injection with or without bone filing mesh containers had the same initial strength and stiffness and exhibited bigger initial strength and stiffness than untreated vertebrae. Thein vivo animal experiments proved that bone filing mesh container had no obvious effect on the vertebrae. These findings indicate that the bone filing mesh container can be used to restore the height and strength of the fractured vertebrae. Moreover, it may eliminate bone cement leakage and therefore increase the surgery safety.

Objective:To investigate the activation of peripheral basophils from patients with rheumatoid arthritis ( RA) and its mechanisms. Methods:The activation markers including CD203c and the proportion of IL-4 positive rate of peripheral basophils from RA patients and healthy controls were detected by flow cytometry. Serum levels of IgE in RA patients and healthy controls were detected by electrochemilu minescence immunoassay. Basophils were negatively isolated and co-cultured with or without purified IgE,anti-IgE as positive control,then,the expression of CD203c and propotion of IL-4 positive basophils were detected by flow cytometry. Results:The expression of CD203c and IL-4 positive rate of basophils from RA patients were higher than that of healthy controls (P<0. 05). Serum levels of IgE in RA were higher than that of healthy controls (P<0. 05). After co-cultured with isolated IgE from RA patients,basophils negatively isolated from healthy controls were activated,and higher expression of CD203c and proportion of IL-4 (P<0.05). Conclusion:Basophil activation is related with development of RA,and its activation is mainly mediated by IgE. Targeting basophil and its activation pathway would be expected to provide new strategies for the treatment of RA.
