4.Investigation of status quo of self-perceived burden of young and middle-aged patients with first-attack of ischemic stroke and analysis of its influencing factors
Chinese Journal of Practical Nursing 2014;30(4):32-35
Objective To know the self-perceived burden (SPB) of young and middle-aged patients with first-attack of ischemic stroke and to analyze the influential factors of SPB as well as its relevance to the quality of life.Methods The patients' general information questionnaire,SPB Self-evaluation Scale,QOL-BREF were adopted to investigate young and middle-aged patients with first-attack of ischemic stroke.Results 100 patients were included,66 were male,34 were female.The Minimum age was 19.4 years old.The maximum age was 59 years old.The mean age was (50.80 ± 7.98) years old.The average SPB score was (24.21 ± 7.39) points,which was in the medium level.31 cases (31%) didn't have obvious SPB; 65 cases (65%) suffered mild-to-moderate SPB; 4 cases (4%) claimed they had severe SPB.There was negative correlation between the SPB and their quality of life.The multi-factor analysis showed that gender,the patients' understanding of disease,and caregivers' health situation were the influential factors of SPB.Conclusions Since self-perceived burden is common in young and middle-aged patients with ischemic stroke,clinical nurses should assess patients' self-perceived burden so as to provide targeted nursing intervention and health education,thereby to ease the burden on patients' self feeling,eventually to improve the level of their mental and physical health.
5.Local decompression and selective interbody fusion with pedicle screw fixation technique for the treatment of degenerative lumbar scoliosis
Chinese Journal of Tissue Engineering Research 2016;20(39):5807-5812
BACKGROUND:Conservative treatment is mostly invalid in treatment of severe degenerative lumbar scoliosis-induced low back pain, so surgical intervention is general y required. Repair methods are decompression, rigid fixation, and selective interbody fusion for the“responsible vertebra”to re-establish normal lumbar curvature, spinal balance and good stability. OBJECTIVE:To investigate clinical curative effect of local decompression and selective interbody fusion with pedicle screw fixation technique for the treatment of degenerative lumbar scoliosis. METHODS:Data of 57 cases of degenerative lumbar scoliosis from Armed Police Corps Hospital of Hunan Province from January 2011 to January 2014 were retrospectively analyzed. According to clinical characteristics of the patients, selective fusion, local decompression and pedicle screw fixation were used for repair. The imaging analysis and Suk criteria were used to evaluate fixation, decompression and bone fusion. Japanese Orthopaedic Association scores were utilized to assess therapeutic effect. RESULTS AND CONCLUSION:(1) Operation time was 157-255 minutes, averagely 176 minutes. Amount of bleeding was 480-1 700 mL, averagely 835 mL. Postoperative drainage volume was 140-210 mL, averagely 155 mL. (2) 57 patients were fol owed up for 12-38 months. Postoperative X-ray revealed that Cobb’s angle was (3.8±2.1)° on the coronal plane after treatment, and the correction rate of lordosis was 54%. The sagittal Cobb’s angle was (6.3±10.5)°, and the correction rate of lordosis was 35%. According to Suk standard, the fusion rate of vertebra was 95%. According to low back pain score system recommended by Japanese Orthopaedic Association scores, the effective rate was 91%at the end of fol ow-up. (3) There were 2 cases of cerebrospinal fluid leakage, 1 case of nerve injury, and 1 case of pedicle screw failure, no infection, no blood vessel injury. (4) These findings suggest that according to imaging data and self clinical features, local decompression and selective interbody fusion with pedicle screw fixation technique for the treatment of degenerative lumbar scoliosis can rebuild and stabilize degenerative lumbar scoliosis in the coronal and sagittal planes to different degrees, with satisfactory clinical curative effect.

OBJECTIVE:To provide reference for regulating pediatric clinical drugs. METHODS:Package inserts of pediatric drugs used by the outpatient,inpatient and emergency pharmacies of our hospital during January and March in 2015 were collected. The information about pediatric drugs in the package inserts,including drug name,indications or functions,specification,adminis-tration and dosage,was calculated and analyzed. 815 kinds of drugs applicable to adults and children in our hospital were studied to summarize and analyze the dosage form,specification and dose of pediatric applicable drugs. RESULTS:438 package inserts were collected,including 327 related to chemicals and biologicals among which those imported or produced by sino-foreign joint venture were labeled with more complete information about drug use for children compared to those made in China,and 111 rele-vant to Chinese patent medicines and natural medicines for which there were significantly insufficient information about drug use for children. The applicable drugs with the dosage form for children and those with the specification therefor respectively accounted for 51.17% and 31.65% of the above-mentioned 815 kinds of drugs,and were mainly available as injections,tablets or capsules, granules and oral liquid. The drugs labeled with the dose based on the age group of children such as infant,preschooler,school child and adolescent(1-18 years old)accounted for 61.24% of those with the specification for children,the drugs labeled with the dose for babies (28 d-1 year old) accounted for 26.74% thereof,and the drugs labeled with the dose for neonatus (younger than 28 d)accounted for 12.02% thereof. CONCLUSIONS:The label information and variety of pediatric applicable drugs are marked-ly insufficient. It is suggested that our country should formulate relevant policies,strengthen the development of pediatric drugs and improve the data for clinical use thereof to ensure the safety of clinical use for children.
