Objective: To explore the prognostic relationship between initial absolute lymphocyte count(ALC) of peripheral blood and primary immune thrombocytopenia (ITP) in children, in order to provide basis for judging the prognosis and treatment of ITP in children. Methods: Clinical data of 166 children with primary ITP in children admi-tted at the Affiliated Hospital of Guizhou Medical University from January 2014 to March 2018 were analyzed retrospectively, and they were followed up by clinic and telephone, the prognostic factors (gender, age, ethnicity, inducement, bleeding, initial ALC, platelet count and treatment) were statistically analyzed, and the relationship between ALC of peripheral blood and the prognosis of children with ITP was observed. Results: Of 166 children with ITP, 89 cases (53.6%) had remission within 3 months, 18 cases (10.8%) within 3-12 months, 20 cases (12.0%) within 1-4 years, a total of 39 cases (23.5%) were refractory (no remission in 1-10 years), the remission rate within 1 year was 64.5%, the total remission rate was 76.4%.ALC of remission cases was (4.58±2.87)×10⁹/L within 3 months, (4.47±2.04)×10⁹/L within 3-12 months, and (2.86±1.61)×10⁹/L within 1- 4 years.Thirty-nine cases (23.5%) were refractory(no remission in 1-10 years), ALC of them was (2.07±0.98)×10⁹/L, and there were significant differences among different groups (F= 12.06, P<0.01). Univariate analysis showed that age (F=27.28), pre-morbidity history of infection and vaccination history(χ²= 9.31), initial ALC (F=12.06) at initial diagnosis were related with the prognosis of children with ITP (all P<0.05). Multivariate analysis showed that the history of infection before onset, the history of vaccination(95%CI: 0.19 to 1.51, P<0.05)and initial ALC(95%CI: -0.64 to -0.23, P<0.001) at the time of initial diagnosis were independent factors affecting the prognosis of children with ITP.The receivers operating characteristic (ROC) was drawn with the development of chronic disease (course >12 months) as state variable and ALC as test variable.The area under curve(AUC) was 0.765(P<0.05), cut-off point was 3.925×10⁹/L, sensitivity was 0.542, and specificity was 0.966. Conclusions Initial ALC can be used as one of the prognosis index of ITP in children, and low ALC is the risk signal for chronic development of ITP in children.

Objective To explore the relationship among depression,anxiety and social support in elderly patients in community outpatient clinic. Methods A total of 551 elderly outpatients from two com-munity health service centers of Hongkou District in Shanghai were evaluated with patient health question-naire-9 (PHQ-9),generalized anxiety disorder-7 (GAD-7),perceived social support scale( PSSS) for de-pression,anxiety,physical health and social support. Results The prevalence rates of depression and anxiety were 26. 1% and 17. 2%,respectively. The scores of PHQ-9 and GAD-7 were 2. 0(4. 0) and 1. 0(2. 0). There were statistically significant differences in the scores of family support,friend support,other support and social support among the elderly patients with different degrees of depression or anxiety (P<0. 01). Fam-ily support(B=-0. 196) and friend support(B=-0. 171) were protective factors of depression in elderly pa-tients in community outpatient clinic. Age,family support and friend support were protective factors of anxiety in elderly patients,while gender and fluctuation of physical diseases were protective factors of anxiety(P<0. 05). Con-clusions The depression and anxiety is intimately related to social support in elderly outpatients. Appropriate measures should be taken to optimize social support,mitigate bad mood negative improve their quality of life.
