OBJECTIVE:To observe the clinical efficacy of Shengxuening tablets reducing the risk of microinflammation in maintenance hemodialysis(MHD)patients with renal anemia. METHODS:60 MHD patients were randomly divided into observa-tion group and control group with 30 cases in each group. The total dialysis times of all the patients were 12 h every week at blood flow of 200-250 ml/min and dialysis flow of 500 ml/min. Both groups received routine treatment;observation group was additional-ly given Shengxuening tablets orally 1.0 g,tid;control group was given ferrous succinate 0.2 g,tid,orally;both groups were giv-en subcutaneous injection of erythropoietin (EPO),10 000 IU/time,once a week;treatment for all of the patients lasted for 3 months. The fasting venous blood sample were collected at the beginning of treatment and in the morning every one months. The levels of hypersensitive C-reactive protein(hs-CRP),tumor necrosis factor α(TNF-α),IL-6,hemoglobin(Hb),and hematocrit (Hct)were detected. RESULTS:After 3 months of treatment,total effective rate of 2 groups were 90.00%,the levels of hs-CRP、TNF-α、IL-6 in observation group were much lower than that before treatment and control group after treatment,with statistical sig-nificance(P<0.05 or P<0.01). No severe ADR was found in 2 groups,and the incidence of ADR in observation group(6.67%) was significantly lower than in control group (13.33%),with statistical significance (P<0.05). CONCLUSIONS:Shengxuening tablets have good curative effect,and they can reduce the risk of microinflammation due to the long-term use of EPO and chalybeate.

Objective To analyze the clinical characteristics,prevention,treatment and prognosis of patients with measles,and provide data for further prevention and complication control.Methods Data of 177 patients with measles were collected and analyzed retrospectively.Results Infants (79.1％) and adults (20.9％) accounted for the most part.The clinical symptoms of measles were typical and Koplik's was very common.The incidences of bronchitis and bronchial pneumonia were higher(33/140,22.6％) in infant patients than that in adults,which was more serious in adult patients,and usually accompanied by liver damage (34/37,89.2％).Conclusion Currently measles is mainly typical,and the incidence in children and adults is increasing.In order to control measles,measles antibody titer monitoring and vaccination of measles should be strengthened.

Objective To measure changes of definitive volume of rebuild CT image in three dimensional conformal radiotherapy (3DCRT) treatment planning system (TPS) under different scanning and observing conditions, which may provide a reference in selecting proper condition of scanning and observing, delineating target volume, and delivering treatment plan. Methods A self-made phantom was scanned under different CT scanning conditions, datas were imported to TPS, CT images were rebuilt in three dimensions under different observing conditions, and then the volumes of large, middle and small simulated tumors on CT images were compared with their real volumes. Results The volume defined by rebuilt CT imags in 3DCRT TPS varied according to different scanning and observing conditions. When scanning axial thickness was set at 10. 000 mm, errors of large, middle and small simulated tumor were - 13.60%, - 17. 68% and - 27. 53%, respectively. When 0. 625 mm was set, errors changed to -0. 50%, -0. 68% and -0. 81% ,respectively. When scanning pitch was set at 0. 562, 0. 938, 1. 375 and 1. 750, the errors were - 1.06%, - 1.09%, 5.52% and 4.75%, respectively. Extreme observing condition, window width and window level markedly increased errors of definitive volume of rebuilt CT images with a maximum of 80. 06%. Conclusions This study may provide clues in selecting scanning and observing condition, delineating target volume, and delivering treatment plan.

Objective To evaluate the factors influencing the reproducibility and validity of food group intakes measured by a food frequency questionnaire (FFQ) for Chinese men. Methods A total of 214 adult men were randomly selected from the Shanghai Men Health Study (SMHS), an ongoing cohort study conducted in urban Shanghai. Each subject who had completed the first FFQ survey at recruitment took 24-hour dietary recall (24-HDR) surveys which were conducted once a month for 12 consecutive months and a second FFQ at the end of the study. Two FFQs were administered approximately 1.2 years apart. The food items listed in FFQ and obtained from 24-HDR were categorized into 11 food groups. The factors influencing the reproducibility of the FFQ was assessed by comparing the Pearson correlation of intake levels from the two FFQs, while the factors influencing the validity was evaluated by comparing intake levels from the second FFQ with the multiple 24-HDRs. Results A total of 195 men completed all 12 times of 24-HDR and twice FFQ surveys. The median Pearson correlation coefficients of the food groups between the two FFQs in older vs younger age group were 0.62 vs 0.50;in higher vs lower education level group were 0.58 vs 0.50;in higher vs lower income group were 0.51 vs 0.50;in higher vs lower BMI group were 0.50 vs 0.49. The median Pearson correlation coefficients of the food groups between the second FFQ and 24-HDRs in older vs younger age group were 0.61 vs 0.45;in higher vs lower education level group were 0.49 vs 0.47;in higher vs lower income group were 0.43 vs 0.57;in higher vs lower BMI group were 0.48 vs 0.51. Conclusions Age is the main factor influencing the reproducibility of the food group intakes by a FFQ used in the SMHS, while the factors influencing the validity are age and family income.

Older people generally had low health literacy, age related cognition decline and some even progress into dementia, burden on society was aggravating. Cognition decline of the elderly could lead to the decrease of health literacy. Meanwhile, higher level of health literacy was a protective factor against cognition decline in the elderly. This paper aimed to explore the relationship between health literacy and cognitive function in the elderly population without dementia, and to provide a theoretical basis for improving the health literacy and cognitive function of the elderly.

Objective To investigate the effects of peroxisome proliferator-activated receptor gamma (PPARγ) agonist pioglitazone on delayed neuronal death,apoptosis of neurocytes,and expression of intercellular adhesion molecule-1 ( ICAM-1 ) following traumatic brain injury (TBI) in rats.MethodsThirty-six Sprague-Dawley rats were randomized into sham injury group,control group and pioglitazone treatment group,with 12 rats in each group.TBI model was established by modified Feeney method.Treatment grouP received intragastric administration of pioglitazone at a dosage of 10 mg/kg,and the sham injury group and the control group were lavaged with isometric 0.2％ dimethyl sulphoxide.Paraffin sections of brain tissues collected at 48 hours after TBI were employed to observe delayed neuronal death,apoptosis of neurocytes and expression of ICAM-1 by Nissl staining,TUNEL staining and immunochemistry respectively.Results( 1 ) Cell loss rate of Nissl body in the treatment group [ ( 38.59 ± 1.97 ) ％ ]was significantly lower than that of the control group [ (51.25 ± 4.01 ) ％ ] ( P ＜ 0.05 ),but was higher than that of the sham injury group [ (8.65 ± 1.23 ) ％ ] ( P ＜ 0.01 ).(2) The number of apoptotic neurocytes of the treatment group (31.67 ± 4.76) was significantly lower than that of the control group (45.33 ± 4.68 ) ( P ＜ 0.05),but was higher than that of the sham injury group ( 16.83 ± 2.04 ) ( P ＜ 0.01 ).(3) The mean optical degree of ICAM-1 positive expression of the treatment group (0.26 ± 0.04) was significantly lower than that of the control group (0.31 ± 0.04) ( P ＜ 0.05 ),but was higher than that of the sham injury group (0.10 ± 0.02 ) ( P ＜ 0.01 ).ConclusionsThe PPARγagonist pioglitazone can reduce the apoptosis of neurocytes and protect neurons after TBI.Meanwhile,its suppression of ICAM-1 expression is probably a mechanism of the suppression of inflammatory reaction and neural protection.

Objective To evaluate the prognostic effect of different ratios of fresh frozen plasma (FFP) to packed red blood cells (PRBC) in massively transfused trauma patients.Methods A retrospective cohort study was conducted for 210 trauma patients who received more than 10 units of PRBC during the initial 24 hours from January 2007 to June 2015.The patients were divided into four groups:Group A(PRBC:FFP ≤1,n=41),GroupB (1 ＜PRBC:FFP≤1.5,n=63),GroupC(1.5＜PRBC:FFP≤2,n=30) and Group D (PRBC:FFP ＞2,n =76).At 24 hours after admission,blood transfusion amount,blood transfusion ratios,post-transfusion adverse reactions (allergy,non-hemolytic febrile transfusion reaction,hemolysis,congestive heart failure,pulmonary edema,etc) and coagulation changes [hemoglobin (Hb),platelet count (PC),prothrombin time(PT),activated partial thromboplastin time(APTT),international normalized ratio (INR),etc] were compared among groups.Prognostic markers including sequential organ failure assessment(SOFA),hospital stay,ICU stay,30-day mortality and causes of death were also evaluated.Results Use of PRBC was decreased significantly in Group A than in other groups (P ＜ 0.01),and there were no differences in blood transfusion adverse reactions among all groups (P ＞ 0.05).The coagulation indices (PT,APTT and INR) in Groups A and B were significantly decreased compared to Group D after transfusion (P ＜ 0.05).There were no differences in length of hospital stay and ICU stay among all groups (P ＞ 0.05).Group D was associated with higher SOFA and higher 30-day mortality than other groups(P ＜0.01),but no differences were found in Group A,B and C (P ＞0.05).Meanwhile,ratio of patients died of massive hemorrhage in Group D was also higher than other groups (P ＜0.01).Kaplan-Meier survival analysis showed the survival interval was the shortest in Group D,while the longest in Group B and C.Conclusions Modest transfusion ratios (1.5 ＜ PRBC:FFP ≤2)within 24 hours can substantially improve outcomes in trauma patients.Aggressive ratios may improve coagulation indices and reduce use of PRBC,with no more benefit to the outcomes.

Objective:To investigate the effect of rapamycin on cell growth and migration of gallbladder cancer GBC-SD cells, and to discuss its potential in clinical therapy of gallbladder cancer. Methods: Proliferation of GBC-SD cells treated with different concentrations of rapamycin (12.5, 25, and 50 mmol/L) was examined by MTT assay. Cell cycle distribu-tion and apoptosis of GBC-SD cells treated with different concentrations of rapamycin were determined by flow cytometry. Migration ability of GBC-SD cells was assessed by Transwell assay. The expression of mTOR (mammalian target of rapam-ycin) and its phosphorylation in GBC-SD cells were examined by Western blotting assay. Results: Rapamycin significant-ly inhibited the phosphorylation of roTOR, but had no influence on the expression of roTOR in GBC-SD cells. Rapamycin significantly inhibited the growth of GBC-SD cells in a dose-dependent manner (P < 0.01). Raparnycin induced apoptosis of GBC-SD cells and arrested them at the G_1/S phase. Furthermore, rapamycin also significantly suppressed migration of GBC-SD cells as showed by Transwell assay (P < 0.01). Conclusion: Rapamycin can remarkably inhibit the growth and migration of gallbladder cancer cells, probably by inhibition of p-roTOR pathway, induction of apoptosis and cell cycle ar-rest of gallbladder cancer cells.

Objective To evaluate the reliability and validity of the Chinese version of the Newest Vital Sign(NVS). Methods The NVS was translated and back-translated. Cultural adaption of scale was performed by Delphi expert consultation and pilot study. The reliability and validity of the Chinese version of the NVS was tested in 451 Chinese residents. Results Chinese version of the NVS consisted of 6 items with Pearson correlation between item and total score of scale ranging from 0.50 to 0.71. Two factors were abstracted by exploratory factor analysis and explained 61.51% of total variance. Confirmatory factor analysis showed that the fitness of the model was acceptable:comparative fit index was 0.96, Tuker-Lewis index was 0.92, standardized root mean square residual was 0.04, root mean square error of approximation was 0.077. Cronbach α coefficient was 0.71, retest reliability was 0.92. Conclusions Chinese version of the NVS has good reliability and validity, which can be used to test the health literacy of residents in China.
