Results After the nursing intervention,the PANSS scores in observe group are significant lower than those of control group (P

BACKGROUND: Blood pressure of children increases with ages, and is related to anthropometric parameters, diet, sports, and other factors. To analyze relative factor of a little high blood pressure of children provides a scientific evidence for prevention and cure of primary hypertension. OBJECTIVE: To investigate correlation between blood pressure and anthropometric parameters among children. DESIGN: Cross-sectional study. SETTING: Department of Hygiene of Weifang Medical College. PARTICIPANTS: According to cluster sampling, 1 546 pupils in grade three or four were selected from a primary school for physical examination and questionnaires. Totally 1 508 pupils with complete data were regarded as the subjects.METHODS: Partial correlation analysis was used to analyze correlation between blood pressure and anthropometric parameters among children.MAIN OUTCOME MEASURES: Correlation among anthropometric parameters, systolic pressure and diastolic pressure.RESULTS: ① Correlation coefficients of systolic pressure with sex, age, height, body mass, chest circumference of Peason were 0.078, 0.166, 0.337, 0.313 and 0.304 (P ＜ 0.01). ② Correlation coefficients of diastolic pressure with sex, age, height, body mass, chest circumference of Peason were 0.047, 0.120, 0.268, 0.271 and 0.251 (P ＜ 0.01). ③ After controlling two effect of anthropometric parameters on each other, systolic pressure and diastolic pressure were only correlated with height and chest circumference (P ＜ 0.01), but was not correlated with age, sex and body mass (P ＞ 0.05). CONCLUSION: After controlling the effect of anthropometric parameters on each other, systolic pressure and diastolic pressure of children were positively correlated with height and chest circumference.

We reported a simple and fast fluorescence system based on quantum dots ( QDs ) to detect glutamate dehydrogenase ( GLDH) , which inverted glutamate to α-ketogrutarate using NAD+ as a coenzyme. The fluorescence of CdTe QDs was quenched by nicotinamide adenine dimucleotide ( NAD+) through an electron transfer pathway, and the quencher NAD+ could be consumed by adding NAD+-dependent enzymes and corresponding substrates. Based on this principle we introduced GLDH to consume NAD+ in the QDs/NAD+ system, leading to the enhancement of the fluorescence intensity of QDs, which was in proportional to the amounts of GLDH added. Using this fluorescence system, we measured GLDH in a wide concentration range from 10 U/L to 1000 U/L, which was of significance in clinical diagnosis of different kinds of liver diseases.

Objeetive To investigate the relationship among social avoidance and acceptance of disability in burn patients.Methods Totally 127 patients were investigated using Social Avoidance and Distress Scale (SADS),Acceptance of Disability Scale (AODS),demographic information questionnaire and disease related information sheet.Results The points of burn patients' SADS was (21.38±6.75),One-way ANOVA showed that gender,marital status,special parts burns,amputation affected social avoidance significantly.The total score and factors scores of acceptance of disability were all negatively related to the score of social avoidance.Regression analysis showed that acceptance of disability,head burns,gender were the independent risk factors of depression.Conclusions Acceptance of disability were negatively related to social avoidance; Nurse can help them accept the reality of disability,develop the confidence to partici-pate in social communication,and improve the social adaptability.

Objective To investigate the location and expression of hypoxia inducible factor (HIF) subunits in the remnant kidney of 5/6 nephrectomy rats. Methods Remnant kidneys were produced in adult male SD rats by 5/6 nephrectomy. The renal function and histopathological changes were evaluated at week 1, 2, 4, 6, 8 and 12 after operation. Tissues of remnant kidneys were collected to detect the location and expression of HIF-1α and HIF-2α by immunohistochemistry staining and Western blotting. The mRNA levels of HIF targeted genes vascular endothelial growth factor (VEGF) and heme oxygenase-1 (HO-1) were determined by RTPCR. Results (1) 5/6 nephrectomy rats underwent one week of acute renal failure at first[Scr (122.8±22.1) μmol/L] and then developed compensative chronic renal failure [(66.0±3.7)-(66.4±8.4) μmol/L], but the level of Scr increased quickly after week 6 [(66.4±8.4)-(127.8±22.7) μmol/L],concomitantly with progressive tubulointerstitial fibrosis in remnant kidney cortex. (2) In cortex, HIF-1α was expressed only in the atrophic and dilated tubular cells while HIF-2α was located in endothelial, interstitial fibroblasts, and vascular smooth muscle cells. The semiquantitative results of imunohistochemistry and Western blotting revealed that HIF-1α and HIF-2α were both gradually up-regulated during the early stage of remnant kidney, peaked at week 4 and 6, and then gradually down-regulated. (3) The mRNA levels of HIF targeted genes VEGF and HO-1 transiently peeked at week 4 and 6, and then decreased gradually. Conclusions The increased stabilization of HIF-αprotein and transcription of HIF targeted genes at the early stage of this model is a compensation reaction towards hypoxia. The mechanism of decreased expression of HIF-α at the end stage of chronic kidney disease deserves further investigation.

Cryogel is a kind of elastic, spongy hydrogel prepared via addition polymerization from monomers or cross-linking reaction from a polymer at a temperature lower than the freezing point of the solvent. Cryogel has been principally used in molecular imprinting cryogel based solid phase extraction in the field of analytical chemistry, which combines both the advantages of high selectivity of the molecular imprinting and the porous structure, high throughput of a cryogel. Molecular imprinting cryogel can be used as the stationary phase in a packed column, a monolith column, or the adsorbent in a separation membrane. A variety of molecules can act as template molecules, including small molecules, macromolecules, a certain fragment of a macromolecule, and even an inorganic ion. Both a simple template and a complex template can be used. When employing more than a molecule ( or an ion) as templates simultaneously, the method is termed as Mixed template. While high abundance components of a complex sample act directly as mixed template, we name the method as Pending template. Further, while an analogue, an isotopic label, or a fragment of the target substance acts as a template, the method is defined as Dummy template. However, the research on cryogel is insufficient and the application of the cryogel is narrow hitherto.

Objective To investigate the current status of uncertainty in illness in cardiac valvular surgery patients with cardiopulmonary bypass and analyze its influential factor,and provide reference for effective intervention.Methods A total of 208 cardiac valvular surgery patients with cardiopulmonary bypass were recruited from 4 cardiovascular surgery in Guangdong and were investigated with the self-designed questionnaire,Mishel Uncertainty in Illness Scale (MUIS),Connor-Davidson Resilience Scale (CD-RISC),Medical Coping Modes Questionnaire (MCMQ),in the preoperative day and the day before discharge.The data were analyzed by single-factor and multiple-factor analysis.Results The average score of uncertainty in illness in cardiac valvular surgery patients with cardiopulmonary bypass was 99.09±11.41,and 92.3％ of patients got a moderate uncertainty in illness level in the preoperative day.The average score of uncertainty in illness in the patients was 90.33± 10.32,and 91.8％ of patients got a moderate uncertainty in illness level in the day before discharge.Multiple linear regression indicated that,age,cardiac valvular disease types,number of cardiac valvular surgery,optimism and yield were the protective factors of uncertainty in illness level.Average monthly household income,self-improvement,scores of resilience and confront coping were the risk factors of uncertainty in illness level.Conclusion The level of uncertainty in illness in cardiac valvular surgery patients with cardiopulmonary bypass is moderate.Age,average monthly household income,cardiac valvular disease types,number of cardiac valvular surgery,resilience and coping style are factors influencing uncertainty in illness level of patients.

Objective To explore the relationship between resilience and coping style of cardiac valvular postoperative patients with cardiopulmonary bypass.Methods A total of 208 cardiac valvular postoperative patients with cardiopulmonary bypass were recruited from 4 cardiovascular surgery in Guangdong and were investigated with the self-designed questionnaire,Connor-Davidson Resilience Scale (CD-RISC),Medical Coping Modes Questionnaire (MCMQ).Results The average score of resilience in cardiac valvular postoperative patients with cardiopulmonary bypass was (55.38±10.63)points.The average score of tenacity,strength and optimism were (28.21 ±5.87)points,(18.21 ±4.02)and (8.96± 1.85)points respectively.The average score of coping style of confrontation,avoidance and acceptance-resignation were(18.13±3.38),(16.95±1.75)and (9.24±2.47)points respectively.All the sub-scores of the resilience were positively correlated with confrontation,and all the sub-scores of the resilience were negatively correlated with avoidance and acceptance-resignation.Conclusions There is a certain degree of correlation between resilience and copping style of cardiac valvular postoperative patients with cardiopulmonary bypass.Nurses should enhance resilience of the patients,guide the patients to adopt effective coping styles,to promote disease rehabilitation and improve the quality of life.

Objective To clarify the relationship between clinical manifestation and pathological features of IgA nephropathy (IgAN) patients with mild proteinuria and/or hematuria.Methods Clinicopathological data from 316 biopsy-proven IgAN cases (proteinuria＜1 g/24 h and/or hematuria, and Scr＜133 μmol/L) from our hospital between January 1993 and October 2009 were studied retrospectively. The renal histopathology was quantified according to Lee's grading and Katafuchi's semi-quantitative standard, and the risk factors for renal pathological lesions were evaluated using multifactor logistic regression analysis. Results Among these 316 patients, 123 were male and 193 patients were female. The mean age at the time of renal biopsy was (33.10±10.69) years old. Clinical features were found as follows: hematuria with proteinuria was found in 267 patients (84.5%), isolated hematuria in 24 patients (7.6%), and isolated proteinuria in 25 patients (7.9%). 16.5% of patients had hypertension. The percentages of CKD stage Ⅰ, Ⅱ, Ⅲ were 76.9%, 20.9% and 2.2%, respectively. 31.3% of patients presented Lee's grade Ⅲ or more severe.52.8% of patients had various degrees of glomerulosclerosis. Crescent formation was observed in 20.3% of patients. 22.5% of patients showed tubular atrophy;16.8% showed interstitial fibrosis and 24.7% also had renal vascular lesions. The extent of glomerulosclerosis was negatively correlated with eGFR levels, but positively correlated with the amount of proteinuria and mean arterial pressure (MAP) level (P＜0.05). The score of tubulointerstitial lesion was positively correlated with the amount of proteinuria and negatively correlated with eGFR and hemoglobin (Hb)level (P＜0.05). The degree of renal vascular lesion was also correlated to MAP level positively and eGFR level negatively (P＜0.05). Multifactor logistic regression analysis revealed that proteinuria, Scr and Hb at the time of renal biopsy were independent risk factors for severe renal pathological lesions (Lee's grade Ⅲ or more severe) with odds ratio of 8.564, 1.031 and 0.975 respectively (all P＜0.01). Conclusions Severe renal histological lesions and decrease of renal function may be seen in some IgAN patients with mild proteinuria and/or hematuria. The levels of proteinuria,Scr and Hb are the independent risk factors for severe renal pathological lesions. Renal biopsy is important in these patients in order to make diagnosis and individual treatment.

Objective Deep brain stimulation (DBS) can greatly improve the clinical symptoms of Parkinson's disease (PD),but it can poorly improve the similar clinical symptoms of multiple system atrophy P-type (MSA-P);therefore,identification is a necessity for the two diseases before DBS is carried out on these patients;surface electromyography (sEMG) was employed to analyze the surface electromyographic characteristics associated with tremor and rigidity of PD and MSA-P to explore the role of sEMG in the differential diagnosis of PD and MSA-P.Methods Twenty patients with PD and 25 patients with MSA-P,admitted to our hospital from June 2013 to January 2015,were enrolled in the study.The sEMG was performed on all patients on the 2nd d of hospitalization.Tremor frequency,tremor sEMG activity intensity and postural tremor latency were analyzed.Synchronous sEMG activity intensity during passive activities was analyzed.Root mean square (RMS) in two states was calculated,and t-test was applied to compare tremor frequency,postural tremor latency and sEMG activity intensity.Results The incidence of rest tremor in MSA-P patients was 36％ and that in PD patients was 60％,with significant difference (P＜0.05).And the incidence ofpostural tremor in MSA-P ones was 44％ and that in PD ones was 35％,with significant difference (P＜0.05).Besides,the postural tremor latency in MSA-P patients was significantly longer than that in PD patients ([9.3±3.2] s vs.[5.3±2.1] s,P＜0.05).Thepostural tremor and rest tremor frequencies of MSA-P patients ([7.3±2.1] and [6.4±3.6]-Hz) were significantly higher than those in PD patients ([5.3±2.4] and [4.9±1.2] Hz,P＜0.05).In rest tremor,RMS of flexor and extensor in MSA-P patients was significantly decreased as compared with that in PD patients (P＜0.05);in postural tremor,RMS of flexor and extensor in MSA-P patients was significantly decreased as compared with that in PD patients (P＜0.05).During passive activities,RMS of extensor in MSA-P patients was statistically higher than that in PD patients ([27.927.9± 11.4] vs.[18.318.3±6.4] μV,P＜0.05),while there was no significant difference between RMS of flexor in MSA-P and PD patients ([31.1±13.6] vs.[29.2±8.9] μV,P＞0.05).Conclusion The sEMG can be applied in the preoperative differential diagnosis for DBS of PD and MSAP.
