OBJECTIVEMany researchers have conducted studies on child language development and relevant risk factors, but most of these studies were about English-speaking children and few of them were on Chinese-speaking children, and less reports of studies on language development of infants or toddlers are available as compared to those on children above 3 years of age. The objective of this study was to assess the level of vocabulary development of healthy toddlers in urban Beijing and to investigate toddlers' physical and psychological development and socioeconomic status of toddlers' family so as to identify factors related to toddlers' language development and provide basis for instructing parents child-rearing.

METHODThis is a quantitative cross-sectional study. Using Chinese Communicative Development Inventory mandarin version, (CCDI) and related background questionnaire, a survey was conducted among the parents or care givers of 1056 healthy toddlers (16 approximately 30 months), randomly stratified and selected from two areas of four urban districts in Beijing. The children who were born prematurely, who had low birth weight, or who were deaf, dumb or with disability, were excluded from this study. The mothers who were deaf, dumb or having disability were not included in this study, either. Rank sum test was used to compare the vocabulary scores between boys and girls at the same age. Single and multiple factors analysis were used to find related factors.

RESULTSBy 16 months of age, boys could speak about 22 words and girls 84 words on the CCDI. By 29 - 30 months of age, boys could speak about 725 words and girls 752 words on the CCDI. The level of vocabulary development of healthy toddlers in urban Beijing was higher than that reported in previous studies of English-speaking children. Girls had higher vocabulary scores than boys in a few different age groups. Single factor analysis showed that the ages of father and mother, income of father, the language used by care-givers and GDP of the families were factors related to families of toddlers and the age, gender, height, weight and the age at which the toddlers began to speak were factors related to individuals. Multiple factors analysis showed that higher education level of mothers, younger father, earlier beginning of children to speak, toddlers' amiable disposition and emotion, girls, toddlers' age and height positively correlated with toddlers' vocabulary score.

CONCLUSIONThe level of vocabulary development of healthy toddlers in urban Beijing is on the high side. Certain individual and familial factors may influence toddlers' language development. It is suggested that health workers should pay attention to the toddlers' language development. The toddlers' parents and caregivers should be taught how to interact with and talk to their children and how to promote children to develop healthy disposition and emotion.

Objective To disscus the applicability of three surveillance methods for Aedes albopictus in dengue risk indication. Methods Larval and adult mosquito surveillance were conducted in two villages of Guangzhou by using three vector monitoring methods. Meteorological data and dengue cases were obtained in the same period. Results The population dynamics of larvae and adult mosquitoes were affected by temperature and their overall trend was consistent, but there were differences between the abundance of larvae and adult mosquitoes. From December to February the next year, Breteau index(BI) ranged from 5.66 to 24.53 with a risk of level 1 to 3 for dengue fever, while the mosquito and oviposition positive index(MOI) and adult-mosquito density index(ADI) were 0 to 4.00 and 0 to 1 per man-hour, respectively, indicating no risk for dengue fever. In March, compared with BI which indicated a risk of level 3, MOI were 2.13 and 3.77, respectively, representing for no risk. ADI were 4 to 6 per man-hour, indicating a risk of level 1 and level 2, respectively. After April, the dengue risk level reflected by each indicator became to be consistent. Conclusions The risk of dengue fever indicated by BI is always higher than or equal to the risk indicated by the other two. Compared with BI, MOI and ADI are more sensitively in reflecting the activity of Ae. albopictus.

Serotonin (5-hydroxtryptamine, 5-HT), one of the central neurotransmitters, is the most important modulator for emotion regulation, sensory processing, cognitive control, etc. The serotonergic neurons are limited in amount and mainly distributed in the dorsal raphe nucleus (DR) and the median raphe nucleus (MR) in the midline of the brain stem. Previous studies mainly focused on the function of 5-HT neurons in the DR, but little is known about 5-HT neurons in MR. In the present study, with Pet1-Cre transgenic mice and DREADDs technology, we specifically activated or silenced 5-HT neurons in the MR, and aimed to explore their roles in anxiety- and depressive-like behaviors. The results showed that silencing 5-HT neurons in the MR decreased anxiety-like behaviors in the open field and elevated plus maze tasks. Inhibition of 5-HT neurons in the MR decreased depressive-like behaviors in the sucrose preference and forced swim test, while activation of 5-HT neurons in the MR enhanced depressive-like behaviors in the sucrose preference test. These results suggest that the 5-HT neurons in the MR play a key role in regulating anxiety- and depression-like behaviors.

OBJECTIVE: To summarize the clinical and Laboratory characteristics of patients with multiple myeloma (MM) and analyze the prognostic factors. METHODS: Two hundred MM patients were retrospectively analyzed for the following parameters, including peripheral blood, bone marrow morphology, cytogenetics, clinical staging, and response to the chemotherapy in order to summarize related factors affecting overall survival (OS). The prognostic factors were also analyzed. RESULTS: 200 patients with MM were divided into 3 groups according to bone marrow plasma cell percentage (BMPC%) in bone marrow smears: ＜10% group (74 cases, 37.0%), 10%-50% group (75 cases, 37.5%), ＞50% group (51 cases, 25.5%). Compared with the other two groups, patients in BMPC%<10% group were characterized by lower clinical staging levels, lower rates of 13q14 deletion and t(11;14) positive, better response to chemotherapy and favorable three-year OS rate. The univariate analysis showed that prognostic factors indicating favorable outcome as evaluated by OS included age≤55 years old, BMPC%＜10%, WBC＜7.5×10 CONCLUSION The clinical characteristics are different among MM patients with different BMPC% in bone marrow smears at initial diagnosis, and prognostic analysis shows that the BMPC% in bone marrow smears has an effect on OS rate. BMPC% in bone marrow smears at initial diagnosis, age, WBC, Hb, response to the fourth chemotherapy are also the main factors impacting the prognosis of patients.
