Objective To study the reliability, validity, sensitivity, specificity and predictive value of the Standardized Swallowing Assessment (SSA) in assessing swallowing function. Methods Sixty-seven stroke patients with dysphagia participated in the study. They were assessed twice with the SSA within 3 days. In addition, the patients' swallowing was also assessed using videofluoroscopy. Results There was high correlation in all items of the SSA between the two separate assessment sessions. The intraclass correlation coefficient was 0.85 for intrarater re- liability and 0.82 for interrater reliability. The SSA and videoflouroscopy results were highly correlated in terms of their total scores (r = -0.86,P≤0.01). Using the videoflouroscopy result as the standard, the sensitivity and spe- cificity of the SSA were 77.8% and 68.1% , respectively. At the same time, the positive and negative predictive val- ues were 48.3% and 88.9% , respectively. Conclusions The SSA has satisfactory reliability and validity, and higher sensitivity and specificity than videoflouroscopy. It is recommended for assessing swallowing with stroke pa- tients.

One hundred patients with rheumatoid arthritis (RA) were randomly assigned to the medication group (n=38) or combined therapy group (n=62). The quality of life was investigated through the questionnaire before and after 6 months' therapy. Data showed that there was statistically significant difference between the two groups in physical, social, and emotional functions, and self-recognized health status (19.0±9.1 vs 6.6±4.8, 10.0±6.9 vs 3.8±3.3, 6.6±3.2 vs 3.0±1.8, and 11.4±7.6 vs 5.3±3.4) ( all P<0.05 ). Combined therapy could significantly improve the quality of life in RA patients.

Objective: To investigate the birth defect condition in Haidian district of Beijing city, 61 272 live-born infants who were delivered in Haidian Maternal and Child Health Hospital from 2003 to the March of 2009 are analyzed. Methods: Data was collected from the hospital' s medical records and from the birth defect surveillance. Results: Among the newborns studied, 1 076 were found having birth defect (17.56‰). The most common birth defects are congenital heart defect, followed by dysmorphosis of external ear, polydactyly, hypospadia, cleft lip and palate. In addition, three birth defects that are not included in the birth defect surveillance list were enorchia, renal agenesis and giant hemangioma. The birth defect rates of preterm and small for gestational age infants are significantly higher than it of the term infants. The birth defect patterns for these two types of abnormal infants are distinct. Conclusion: We have determined the pattern of birth defects in Beijing, which may help in policy-making regarding the prevention and intervention of birth defects.

Objective To explore the clinical efficacy and adverse reactions of children with acute promyelocytic leukemia (APL) by adopting Chinese children APL-2010-protocol in single center.Methods Forty-seven children with newly diagnosed APL in Soochow University Affiliated Children's Hospital from October 2010 to September 2015 were selected,including 30 boys and 17 girls with the median age of 7 years (1.2-14.0 years).The patients were divided into 3 groups,including 11 cases in the low-risk group,20 cases in the intermediate-risk group and 16 cases in the high-risk group.Their clinical features and therapeutic prognosis were analyzed retrospectively and the clinical efficacies were compared in low-risk group[white blood cell(WBC) ≤ 10 × 109/L,platelets (PLT) ＜ 40 × 109/L],intermediate-risk group (WBC ≤ 10 × 109/L,PLT ≤40 × 109/L) and high-risk group (WBC ＞ 10 × 109/L).Five-year event-free survival (EFS) rate and overall survival (OS) rate of each group were analyzed by using Kaplan-Meier curve method.Results The peak comparative difference of peripheral blood WBC among 3 groups was statisticallysignificant(x2 =7.618,P =0.002).The occurrence rate of disseminated intravascular coagulation (DIC) was 68.8％ and the occurrence rate in the high-risk group was higher compared with low-risk group and intermediate-risk group (x2 =8.217,P =0.016).Arsenic trioxide related side effects including abnormal liver tests,electrocardiogram and anaphylactic reaction were invertible after supportive therapy.Hematologic complete response (HCR) rate in the high-risk group was 93.7％,HCR time was (39.3 ± 2.7) days and molecular complete remission (MCR) time was(71.0 ± 9.7) days.HCR rate in the intermediate-risk group was 95.0％,HCR time was (44.6 ± 3.1) days and MCR time was (80.0 ± 8.2) days.HCR rate in the low-risk group was 100.0％,HCR time was (32.4 ±2.3) days and MCR's time was (71.5 ± 12.0) days.HCR time among 3 groups had statistical significance (F =3.652,P =0.034),but HCR rate and MCR time among 3 groups showed no statistical significance (F =0.318,P =0.729).In the high-risk group,EFS rate was (93.3 ± 6.4) ％,5-year OS rate was (86.7-± 8.8) ％.Meanwhile,5-year OS rate and EFS rate were 100.0％ in other 2 groups.Conclusions Treating patients with APL by using 2010 protocol according to the risk stratification in our center has achieved high long-time survival.The higher the risk,the higher the incidence of DIC in induction period,but eventually achieve a very high rate of 5-year EFS was achieved.No chronic arsenic toxicity or second malignancies were found during the follow-up time.

Objective:To examine the effects of predictive nursing on the scar treatment by fractional carbon dioxide laser.Methods:90 cases with scar who were treated with fractional carbon dioxide laser in our hospital from January 2017 to June 2019. The cases were then divided into the predictive nursing (PN) group and routine nursing (RN) group as control. The adverse reactions, self-efficacy and solution of the patients between the two groups were analyzed.Results:The incidence of adverse reactions in the PN group was 8.89%(4/45), which was significantly ( χ2=8.073, P=0.004) lower than 33.33%(15/45) in the RN group. The self-efficacy score of the predictive nursing group was (38.08±0.62) points, which was significantly ( P<0.05) higher than (26.22±1.27)points in the routine nusing group. The facing dimension scores in the medical coping modes questionnaire table of the PN group was higher than that in RN group, and the yield and avoidance dimension scores were lower than those in the control group, with statistical significance( P<0.05). Conclusions:Predictive nursing in the scar treatment by fractional carbon dioxide laser can contribute to reduce adverse reactions, as well as promote the self-efficacy and coping styles of patients.

Objective:To compare the health knowledge of newly admitted patients with recurrent hypertensive stroke around 10 years, and analyze the influencing factors of health knowledge of patients.Methods:From September 2008 to December 2009 and from September 2018 to December 2019, convenience sampling was used to select newly admitted patients with recurrent hypertensive stroke from 3 ClassⅢ Grade A hospitals in Guangzhou as the research objects, and the Stroke Knowledge Questionnaire (SKQ) was used for investigation. In the two stages around 10 years, 120 and 130 questionnaires were distributed, and 109 and 116 valid questionnaires were returned with the valid response rates of 90.83% and 89.23%, respectively.Results:The education level, per capita monthly income of the family, family history of stroke, diabetes mellitus and hyperlipidemia, and smoking of the patients before and after 10 years were statistically significant ( P<0.05) . After 10 years, SKQ total scores, dimension scores in exercise, medication, stroke risk factors, stroke auras, and stroke management of patients were higher than those of 10 years ago, and dimension scores low-salt diet and smoking were lower than 10 years ago, and the differences were statistically significant ( P<0.05) . Conclusions:The level of health knowledge of newly admitted patients with recurrent hypertensive stroke is higher than that of 10 years ago, but education on low-salt diet and smoking cessation knowledge should be further strengthened.

OBJECTIVE To investigate the effects of matrine （MT） on steatosis Chang Liver cell model induced by oleic acid （OA） and its possible mechanism. METHODS Chang Liver cells were divided into blank group， model group and MT low-dose， medium-dose group and high-dose groups （0.1， 0.5， 1.0 mmol/L）. Except for blank group， the other groups were treated with 1.0 mmol/L OA for 24 h to establish steatosis model， and MT groups were given corresponding concentrations of drugs for 24 h. The activities of steatosis Chang Liver cells were observed； the morphologies of intracellular lipid droplets were observed and lipid content was also determined. The contents of liver function indexes [alanine transaminase （ALT）， aspartate transaminase （AST）， total bilirubin （TBIL）， alkaline phosphatase （ALP）]， as well as mRNA and protein expressions of farnesoid X receptor （FXR）， cytochrome P450 7A1 （CYP7A1） and fibroblast growth factor 19 （FGF19） were all detected. RESULTS OA and MT had no significant effect on the activity of Chang Liver cells. After OA treatment， orange lipid droplets formed in cytoplasm； compared with blank group， relative lipid content and the levels of liver function indexes were increased significantly， while the mRNA and protein expressions of FXR， CYP7A1 and FGF19 were down-regulated significantly （P＜0.05）. After treatment of low， medium and high concentrations of MT， above indexes were all reversed significantly （P＜0.05）. CONCLUSIONS MT could significantly improve the lipid content and liver function indexes of steatosis Chang Liver cells induced by OA though regulating FXR/CYP7A1/ FGF19 signaling pathway.
