Objective To investigate telomerase activity in patients with psoriasis. Methods The telomerase activity in the skin lesions of patients was detected by TRAP (Telomeric repeat amplification protocol)——ELISA which is based upon PCR amplification of the initial telomerase product and detected by ELISA. Results Telomerase activity was detected in the lesions of psoriatic patients, but the level of it was lower in comparison with that in tissues of malignant tumor and K562 cell line. Conclusion These findings support that the increase of telomerase activity may be linked to the pathogenesis of psoriasis and that the telomerase activity can be detected not only in malignant tumors but also in nonmalignant skin diseases.

Cerebral small vessel disease is a common cerebrovascular disease in clinical practice.It is mainly characterized by insidious onset and slow development.Some may have acute attack.The imaging features of cerebral small vessel disease mainly include cerebral white matter lesions,lacunar infarction,cerebral microbleed and cerebral perivascular space expansion.It is closely associated with cognitive impairment.All imaging findings can occur simultaneously and interact,further aggravate cognitive impairment,and ultimately lead to dementia.Therefore,the influence of cerebral small vessel disease on the quality of life and social function of the patients cannot be ignored.

BACKGROUND:Non-operation therapies are commonly used in the treatment of cervical spondylopathy. All of these therapies involve biological mechanics; especially for traction and massage of the cervical vertebrae, they have an obvious property of biological mechanics in rehabilitation of the cervical vertebrae. OBJECTIVE: To probe into the biological mechanics of different rehabilitation methods through comparing the intervention effects between traction and traction combined with massage on cervical spondylopathy.DESIGN: A case-controlled observation. SETTING: Rehabilitation Center of West China Hospital of Sichuan University. PARTICIPANTS: Among the patients who came to the Rehabilitation Center of West China Hospital of Sichuan University between October 2002 and July 2003 for the treatment of spondylopathy, totally 52 patientsmet the criteria for non-operation therapy. They participated in the experiment voluntarily and were randomly divided into 2 groups: the experimental group and the control group, with 26 patients for each. METHODS: ①The patients in the experimental group were treated by traction in combination with massage. Traction was performed once a day,30 minutes each time, 5 times as a course of treatment, and one or two courses of treatment in total. Massage was performed for 8 to 10 minutes each time, once a day, 5 times as a course of treatment, and one or two courses in total. ② The patients in the control group were treated with traction only. Cervical Spondylopathy Therapeutic Effect Rating Scale was adopted to evaluate the effects, three items were selected to set as our scoring criterion, which included clinical symptoms, physical examinations and activities of the daily life (ADL). The improvement index was figured out on the basis of the pre-treatment score and post-treatment score. The improvement index is worked out by the following equation: improvement index = (The post-treatment score-pre-treatment score) / the post-treatment score. The improvement index was evaluated by physicians after the treat ment. Effectual: Clinical symptoms and body symptoms were obviously improved; work, learning, and daily life are not affected. Effective: Clinical symptoms and body symptoms have improved , and work, learning, and the daily life are partially affected. In-effective: There was no improvement in clinical symptoms and body symptoms and showed no effect on the work ,learning, and the daily life. MAIN OUTCOME MEASURES: ① Score of the treatment of cervical spondylopathy of the patients before and after the treatment. ② Intervention effect on the patients after the treatment RESULTS: Totally 52 patients with cervical spondylopathy entered the stage of result analysis with none missing in the midway. ① Comparison of the scores of the treatment of cervical spondylopathy of the patients before and after the treatment: After the treatment, the score in the experimental group was significantly higher than that in the control group [ 16.431 ±3.212,13.147 ±3.036 ( t =4.676, P ＜ 0.01 )], and the improvement index of the patients in the experimental group was significantly higher than that in the control group [0.505±0.163,0.368±0.145 (t=3.860, P ＜ 0.01 )]. ② Comparison of the intervention effects on the patients after the treatment: The effectual rate of the experimental group was higher than that of the control group (80.8%,46.2%).CONCLUSION: The approach of traction combined with massage is superior to simple traction. Different rehabilitation approaches have different properties in biological mechanics. It has showed that the force change is important to therapeutic effectiveness on cervical spondylopathy.

Objective To explore the value of 64-slice multi-detector computed tomography coronary angiography (64SCTA) in detecting the coronary artery plaque and to analyze the risk factors for unstable plaque. Methods A total of 112 inpatients who had been diagnosed as coronary artery disease by 64SCTA received catheter coronary angiography (CAG). The levels of serum endothelin-1 (ET-1), matrix metalloproteinase-9 (MMP-9), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and high-sensitivity C-reactive protein (hs-CRP) were measured. The effect of 64SCTA in detecting the coronary artery plaque was evaluated as compared with CAG. The patients were divided into the soft plaque group (n=51) and non-soft plaque group (n=61) according to the CT value of correctly detected plaque. The differences in the above detection indexes between two groups and the risk factors for soft plaque forming were analyzed. Results The 64SCTA had 87.4% sensitivity and 87.1% specificity in detecting coronary artery plaque, the positive predictive value was 82.2% and the negative predictive value was 91.0%. There were significant differences between soft plaque group and non-soft plaque group in the levels of MMP-9, IL-6, hs-CRP, the number of coronary lesions and the composition ratios of gender, diagnosis and diabetes. Logistic regression analysis showed that MMP-9>5.231 ng/L (P=0.0215, OR=2.33, 95%CI 1.13-4.79), hs-CRP>3.583 mg/L (P=0.0008, OR=4.32, 95%CI 1.84-10.15) and unstable angina pectoris (P=0. 0339, OR=4.33, 95% CI 1.12-16.77) were the risk factors for soft plaque formation. Conclusions 64SCTA has highervalue in detecting the coronary artery plaque, and is one of most reliable means in non-invasive methods. MMP-9, hs-CRP and unstable angina pectoris are independent risk factors of plaque instability.

This article reviews the research progress of the predictors of PSCI, including demographic characteristics, imaging characteristics of stroke onset, stroke itself characteristics, and molecular markers, hoping to help screen high-risk patients and intervene in time to delay the occurrence and development of PSCI.

Objective:To analyze the current status of frailty in elderly patients undergoing cardiac surgery, explore its risk factors, and establish a predictive model of frailty in order to provide targeted and predictive nursing programs.Methods:A total of 205 cardiac surgery patients admitted to the first affiliated hospital of Xinjiang Medical University from March 2015 to January 2019 were selected as the study subjects. Patients were divided into 2 groups according to whether they were frail: the frailty group ( n=78) and the control group ( n=127). Logistic regression was used to analyze the risk factors that affect the frailty of elderly patients undergoing cardiac surgery. The receiver operating characteristic curve (ROC) was used to evaluate the effectiveness of model X [consisting of body mass index (BMI), Mini-Mental State Examination (MMSE) score, number of diseased patients, and number of drugs] in diagnosing frailty in elderly patients undergoing cardiac surgery. Results:Of the 205 patients, 78 (38.05%) showed frailty. The proportion of high school education level and above, Tinetti Gaitassessment (TGA) score≥24 and MMSE score≥27 in the frailty group was lower than that in the control group, and the proportion of Geriatric Depression Scale-15 (GDS-15) score≥7, the number of diseases≥3 and the number of drugs≥5 in the frailty group was higher than that in the control group ( χ2 value was 9.254-26.061, P<0.05). Logistic regression analysis showed that BMI, MMSE score, number of diseased, and number of medications were independent risk factors for frailty in elderly patients undergoing cardiac surgery ( OR value was 0.032-5.275, P<0.05). The area under the ROC curve, sensitivity and specificity of frailty in elderly cardiac surgery patients assessed by model X were 0.913, 75.61% and 96.77%, respectively. Conclusion:The incidence of frailty is higher in elderly patients undergoing cardiac surgery. Model X can diagnose the frailty of elderly patients undergoing cardiac surgery and help clinical nurses to carry out targeted care.
