Actinic keratosis (AK) is a precancerous state of the skin, which shows epidermal dysplasia of different degrees. The cellular DNA content and proliferative activity of the skin lesions in 27 cases of AK were analyzed with flow cytometry. The results showed that the PI (proliferating index) in AK was higher than that in normal skin (P

OBJECTIVE To explore how to establish the hospital infection control process by using evidence-based medicine.METHODS In order to establish the hospital infection control process for every department the data related to hospital infection were collected through searching related literature from MEDLINE,Chinese biomedicine literature database authorized by Institute of Medical Information.Chinese Academy of Medical Sciences and evidence-based medicine network then estimated thoroughly.RESULTS The incidence of hospital infection patients,environment sanitation inspection,medical staff hand-washing compliance,and occupational exposure all were up to scratch(P

Objective: To explore the function of multimedia teaching in rural doctor CPR training, to discuss the training methods for how to improve the CPR training in rural doctors. Methods: The method uses the grouping research the method, supposes the experimental group and the control group according to the stochastic grouping principle, separately uses the multimedia union heart and lungs anabiosis computer teaching to 62 rural doctors to simulate the human teaching method or the traditional version book teaching method situation conducts the track investigation and study. Results: In the result 62 examples experiments the group and the control group the result has the highly remarkable difference in the theory knowledge test and the operation inspection, has statistics significance (x2=7.4, p<0.01). Conclusion:The conclusion multimedia union heart and lungs anabiosis computer teaching simulates the human teaching training to have the remarkable function in rural doctor in the CPR, should give to promote.

Objective To provide a dimension calculating method of metacarpal and phalange bones with individual character for surgery and prosthesis design.Methods 102 X-ray films of pairs of healthy adult hands(52 male and 50 female) were measured and a mathematical relation model were described.Another 30 hands were put in a practice for further research.All of the data were analyzed by SPSS software.Results It was found that 98.98% items were positive correlation and their correlations were significant(r=0.157 ~0.925,P

Objective To examine the expression of angiopoietin-like protein(ANGPTL)3 in kidneys from children with primary nephrotic syndrome. Methods Immunohistochemistry for ANGPTL3 was performed in kidney biopsies from patients with nephrotic syndrome or hematuria, including MCD (n=31), MN(n=6), FSGS (n=6), TBMN (n=10), IgA nephropathy (IgAN) with mesangial proliferation (n=16). Normal renal tissue of 2 cases with nephrectomy for tumor were used as control. According to the episode, four groups were divided ("12 months"). The expression was quantitatively examined with IMS color image analysis system, using positive index (PI) as sediment degree of ANGPTL3 in glomeruli or tubules. Immunofluorescence for ANGPTL3 co-labeling with WT1 and perlecan was applied to show the distribution of ANGPTL3. Results (1) The PI levels of ANGPTL3 in glomeruli of MCD(7.49?1.96) and MN (6.27?0.98) were significantly higher than those of TBMN (0.02?0.001), FSGS (3.14?0.49) or normal control(0.02?0.001) respectively (all P

Objective To summarize the placement, maintenance, and safety of a high-pressure resistant peripherally inserted central catheter. Methods Ten patients were peripherally placed with this catheter (included 4Fr-single lumen, 5Fr-dual lumen, and 6Fr-three lumen) using ultrasound-guided Seldinger technique in Peking Union Medical College Hospital in August 2010. The therapeutic effectiveness and safety were evaluated. Result Ten catheters were inserted successfully into the upper arms, with few complications noted during routine maintenance. Conclusions This peripherally inserted central catheter can be used for high-pressure injection, central venous pressure monitoring, and fast flow-speed transfusion. Therefore, it can be successfully applied for contrast-enhanced CT angiography and massive fluid infusion.

ObjectiveTo discuss the application value of high frequency ultrasound (HFUS) characteristics, acoustic radiation force impulse (ARFI) imaging technology and contrast-enhanced ultrasound (CEUS) in the diagnosis of soft tissue hemangioma.MethodsTo retrospectively analyze the clinical data of 44 cases of soft tissue hemangioma that were treated in Capital Medical University Affiliate Beijing Chaoyang Hospital from August, 2013 to May, 2014, and to analyze the difference between the characteristics of HFUS, ARFI and CEUS in soft tissue hemangioma and normal surrounding tissue.ResultsHFUS shows the features of morphological diversity of sinus shape expansion tube structure, unclear boundary, irregular configuration, compressibility and partial strong echo in the phlebolith. Color Doppler ultrasound (CDFI), detects abundant interphase red-blue bloodstream signal slowly and consistently. The blood signal is strengthened after partial compression. CDFI shows more vein spectrum in the lesion. The discrepancy of comparison between VTQ and SWV value of soft tissue hemangioma and surrounding muscular tissue possesses statistical significance [(1.082±0.183) m/svs (1.414±0.331) m/s,P<0.01]. Ultrasound contrast can show the relationship between diseased region and surrounding tissue clearly, which is beneficial to the selection of operation method and prognosis.ConclusionThrough conventional two-dimensional ultrasound and high frequency CDFI, and further combining the acoustic pulse radiation ARFI technology and CEUS technology, the soft tissue hemangioma can’t only be more accurately diagnosed, but also provides more reliable diagnostic basis for clinic.

Objective:To explore the effect of virtual reality (VR)-based baduanjin exercise on the cognition, physical functioning and life quality of elderly persons with mild cognitive impairment (MCI).Methods:Fifty-seven mildly impaired elderly persons were randomly divided into an observation group ( n=29) and a control group ( n=28). Both groups were given routine care and health education in their nursing homes, while the observation group additionally performed 50 minutes of VR baduanjin exercise three times a week for 24 weeks. Both groups were assessed using the Montreal cognitive assessment (MoCA), the Rivermead behavioural memory test (second edition) (RBMT-Ⅱ), a digit-symbol substitution test (DSST) and the Trail Making Test (TMT). The short physical performance battery (SPPB) and Alzheimer′s disease quality of life (QOL-AD) instrument were also administered before and after the 24-week intervention. Results:After the intervention the average MoCA, RBMT-Ⅱ, DSST, TMT-A, SPPB and QOL-AD results of the observation group were all significantly better than before the intervention and better than the control group′s averages. The observation group also performed better on the 5 times sit-to-stand test, the tandem standing test and a walking speed test after the intervention.Conclusions:VR-based baduanjin practice can effectively improve the cognition and physical functioning of mildly impaired elderly persons, as well as improving their quality of life.

colon cancer and to find out treatment and prevention by using different gene changes.

The fact that incision inflammation ratio is related to the time of preoperative skin preparation was explored.227 cases made skin preparation a day or two hours before surgical operation were analysed prospectively in this study.There is statistical significant difference between the two periods of preoperative skin preparation:the second (two hours before surgical operation) can greatly lower the ratio of incision inflammation.
