1-(2,6-Dimethylphenoxy)-2-(3,4-dimethoxyphenylethylamino) propane hydrochloride(DDPH) caused parallel rightward shifts of the phenylephrine(Phe) concentration-contractile response curves and did not suppress the maximal contractile response to Phe (pA2=7.24) in isolated rabbit urinary bladder smooth muscle. DDPH decreased the parameters of cystometry in urethane-anesthetized rats. Thirty minutes after DDPH (25 and 50 mg*kg-1 ig) administration, bladder capacity, voiding pressure, voiding threshold pressure were significantly decreased. With the observation of light-microscope and electron-microscope technique, DDPH (25 and 50 mg*kg-1*d-1 ig for 4 weeks) also inhibited the development of testosterone propionate-induced benign prostatic hyperplasia in rats. The results indicate that DDPH may inhibit benign prostatic hyperplasia and improve the urinary flow.

Dietary restriction (DR) can delay senescence,prolong lifespan of mammals and improve their learning-memory activity.The purpose of the study was to explore the effects of DR on hypolipidemic action and liver function of mice with hyperlipidemia.To investigate these effects,hyperlipidemia mouse models were established with high-fat diet (HFD) (34％ of energy),then randomly divided into HFD group,DR30％ group and DR50％ group.Mice in DR30％ and DR50％ group were respectively supplied with HFD as much as about 70％ and 50％ of the consumption of HFD in the mice of HFD group.Rats in control group were fed routinely.After DR for 5 weeks,the average body weight,liver weight,liver index,serum lipids and glucose levels in both DR groups decreased significantly as compared with the HFD group (P＜0.05 or P＜0.01),so did alanine aminotransferase (ALT),aspartate aminotransferase (AST),lactate dehydrogenase (LDH) levels and the ratio of LDL-C/HDL-C in the DR50％ group (P＜0.05 or P＜0.01).Histopathology examination of liver tissues further proved ameliorative effect of DR on liver function.Western blotting showed that DR significantly increased the expression of silent mating type information regulation 2 homolog 1 (SIRT1) in liver and adipose,while notably decreased the expression of peroxisome proliferators-activated receptors-gamma (PPARγ) in adipose (P＜0.05 or P＜0.01).The increase of SIRT1 and decrease of PPARγ may be a mechanism by which DR reduces blood lipids and ameliorates liver function.

Objective: To understand the relationship between mental health status and vision-related quality of life( VRQL ) of students with moderate and high myopia, and to provide basis for the optimization of VRQL. Methods: Using convenient sampling method, the 8-18 years old students with moderate and high myopia were selected from Sichuan, Chongqing and Zhejiang. The mental health status and VRQL of students with moderate and high myopia were evaluated with Hospital Anxiety and Depression Scale and Quality of Life Scale for Ametropia. The multiple linear regression model was used to analyze the influencing factors for VRQL. Results: A total of 360 questionnaires were sent out and 354 were effectively recovered, with an effective rate of 98.33%. There were 116 ( 32.77% ) boys and 238 ( 67.23% ) girls; the median age was 16.65 years old. There were 211 ( 59.60% ) cases of moderate myopia and 143 (40.40%) cases of high myopia.There were 141 ( 39.83% ) found to be anxious and 176 ( 49.72% ) depressed. The median score of Quality of Life Scale for Ametropia was 64. The results of multiple linear regression analysis showed that sex ( β＇= -0.179 ), diopter ( β＇= 0.208 ), eyesight with glasses ( β＇= -0.229 ) and anxiety ( β＇= 0.439 ) were influencing factors for VRQL. Conclusion The mental health problems of the students with medium and high myopia are prominent; anxiety has a significant impact on the VRQL of the students.

Abstract: Objective To analyze the effect of nutrition package on the nutritional status and prevalence of children in rural areas of Hainan Province, and provide scientific basis and suggestions for further improving the nutritional and health status of children in this region. Methods　Four cities and counties were randomly selected as the intervention group, and four cities and counties matched with the intervention group in terms of population, economy, social culture, maternal and child health work foundation of township health centers, physical nutrition and health status were selected as the control group.With the combination of monitoring and prospective cohort study, infants in the intervention group and the control group were studied from June 1, 2020, and they were intervened for 12 months with supplementary food nutrition package. Before and after intervention, the nutrition and health status of infants aged 6-24 months in the intervention group and the control group were investigated to evaluate the nutritional and health effects of supplementary food nutrition package for infants aged 6-24 months in rural Hainan Province. Results　A total of 999 infants were investigated, including 427 in the intervention group and 572 in the control group. After 12 months of nutritional intervention, there was no significant difference in weight-for-age Z-score (WAZ) and height-for-age Z-score (HAZ) and weight-for-height Z-score (WHZ) between the intervention group and the control group (P>0.05). The rate of emaciation of the intervention group was 1.64%, which was significantly lower than 3.67% of the control group (P<0.05). There were no significant differences in the rate of growth retardation (2.81% and 3.32%, respectively) and underweight (0.47% and 1.92%, respectively) between the intervention group and the control group (P>0.05). The rate of respiratory infection and diarrhea in the intervention group were 9.13% and 1.17%, which were significantly lower than corresponding 23.25% and 3.15% in the control group (P<0.05). The hemoglobin of the intervention group and the control group were 117.24 g/L and 114.51 g/L respectively, and the rates of anemia were 11.11% and 22.84% respectively, the differences were statistically significant (P<0.05). Conclusions　The intervention of nutrition package in rural areas of Hainan Province has achieved the expected results, and supplementary food nutrition package has reduced the incidence of malnutrition and respiratory infection and diarrhea in recent two weeks in infants and anemia to a certain extent. We should attach great importance to the supplementary nutrition package for right-age children and promote the growth and health of children in rural areas through supplementary nutrition package, and continuously improve the nutrition and health level of children in Hainan Province.

Objective To investigate the clinical value of the simple clinical score (SCS) in Emergency Department.Methods A total of 655 patients with critically illness admitted from July 1,2011through August 31,2011 were enrolled to evaluate the clinical application of SCS in emergency rescue room by analysis of the relationship between SCS and outcome of patients,and the correlation between each factor of SCS and the risk of death. Results The higher SCS,the higher hazard ratio for death.Differences in the hazard ratio for death among groups with different scores of SCS were statistical significance ( P ＜ 0.01 ).According to Chi-square test,there were significant differences in each factor ( except body temperature &unable standing or need Home Health Aide) among the groups of SCS ( P ＜ 0.05 ). Binary logistic regression analysis of each factor showed that age,diabetes,coma,pulse,systolic pressure and respiratory rate had significant correlation with patient mortality. After logistic regression analysis,age,diabetes,coma,pulse,systolic pressure and respiratory rate are significantly related to the mortality of patients.Conclusions The SCS scoring system is useful to make a precise evaluation of critically ill patients in the emergency department.When emergency rescue is carried out,particular stress should be focused on age,diabetes,coma,pulse,systolic pressure and respiratory rate.

OBJECTIVETo evaluate the significance of quantitative detection of CCAAT/enhancer binding protein zeta (C/EBP zeta) transcripts in patients with chronic myeloid leukemia (CML).

METHODSReal-time quantitative polymerase chain reaction (RQ-PCR) assay was established and performed to measure the transcript level of C/EBP zeta in the bone marrow mononuclear cells from 76 patients with CML at different stages.

RESULTSC/EBP zeta transcripts were significantly decreased in CML patients in chronic phage, accelerated phage, and blastic crisis (median 2.5, 3.31, and 2.22, respectively), compared to that in normal controls (median 12.20). Further down-regulation of C/EBP zeta was observed in the patients resistant to interferon (median 1.56); however, its expression level returned to normal in the patients who obtained complete cytogenetic remission (median 15.43).

CONCLUSIONC/EBP zeta was down-regulated in CML patients, which might play a role in the leukemogenesis.
