Objective · To survey the willingness to enroll in nursing homes among the elders in Shanghai and explore its predictors. Methods · A field survey was performed to collect data from 641 elders aged 60 years old and above in six community health centers in Shanghai. Sociodemographic variables, willingness to use nursing home, perceived barriers and perceived benefits were measured. Results · The questionnaire is with good structural validity and good intrinsic reliability. KMO index, P value of Bartlett's test of sphericity, and the range of Cronbach's α coefficients were 0.862, 0.000,and 0.739-0.824, respectively. Among the respondents, 46% were willing to enroll in a nursing home in this survey. Age had significant influence on their willingness (P=0.045). After adjusting for age, the multivariate Logistic regression analysis showed that shame (OR=0.76, 95% CI=0.62-0.94), adaptability (OR=0.61, 95% CI=0.50-0.74) and perceived benefits (OR=1.63, 95% CI=1.32-2.03) were related to willingness (P<0.05).Conclusion · Elders in Shanghai have a relatively high level of willingness to enroll in nursing homes, especially the elders aged from 60 to 69. Shame and adaptability of elders, and the services provided by nursing homes were the predictors of the elders' willingness.

OBJECTIVETo examine the distribution and trends of hospitalization rates for coronary heart disease (CHD) from 2007 to 2009 in Beijing.

METHODSWe calculated hospitalization rates for CHD using data from Beijing Hospital Discharge Information System. Information of census registered population in Beijing was obtained from Beijing Municipal Bureau of Statistics. CHD includes acute myocardial infarction, unstable angina and other forms of CHD. Age-standardized hospitalization rates for CHD per 100 000 population aged 25 years or more were calculated.

RESULTSDuring 2007 - 2009, a total of 248 049 patients aged 25 years or more hospitalized in Beijing with the primary discharge diagnosis of CHD were enrolled, of whom 73.7% were permanent registered Beijing citizens. The average hospitalization rate for CHD in 2007 - 2009 was 651.2/100 000 for the permanent residences in Beijing (741.2/100 000 in men, 560.9/100 000 in women). The highest average hospitalization rate (671.9/100 000) was seen in exurban area compared to other areas in Beijing. The average hospitalization rate for acute myocardial infarction, unstable angina, and other CHD was 126.4/100 000, 226.4/100 000 and 298.4/100 000, respectively. The hospitalization rate for CHD increased 18.1% from 2007 to 2009 (from 598.1/100 000 to 706.5/100 000). The same trend was seen in women (20.2%) and men (16.6%). The hospitalization rates of CHD in the urban, suburban, and exurban areas of Beijing all increased in the three years, and the greatest increase (36.6%) was found in exurban area. Hospitalization rates of acute myocardial infarction and unstable angina increased 24.5% and 55.3%, respectively, in the three years, while hospitalization rates of other CHD decreased 5.7%.

CONCLUSIONSThe hospitalization rate of CHD is higher in men than in women in Beijing. The hospitalization rates for CHD increased from the observation period, especially in those living in exurban area. Awareness of the magnitudes and trends of CHD hospitalization rates is of great importance in evaluating the burden of cardiovascular disease, allocating and utilizing health care resources, and estimating the health insurance for Beijing.

OBJECTIVETo investigate the impact of congenital cytomegalovirus infection on the hearing ability in infants.

METHODSBy using the tools of distortion product otoacoustic emission (DPOAE) and auditory brain-stem response (ABR), the hearing ability of 38 infants with congenital cytomegalovirus infection and 16 cases of normal controls during neonatal periods was screened with a follow-up study at 6 and 24 months.

RESULTIn infants with congenital cytomegalovirus infection, 86.8% (66/76) ears at neonatal stage and 76.3% (58/76) ears at 6 months passed the tests; while in normal controls, 96.9% (31/32) ears passed the tests. The reaction threshold of ABR V in infants with congenital cytomegalovirus infection was higher than that in normal controls (P<0.005). Furthermore,in infants with congenital cytomegalovirus infection, 13 ears (17.1%) were extreme hearing loss, 5 ears (6.6%) were severe hearing loss, and 6 ears (7.9%) were moderately severe hearing loss. The incidence of hearing loss during the follow-up was 7.9% (3/38) at neonatal stage, 23.7% (9/38) at 3-4 months, and 7.9% (3/38) after 6 months.

CONCLUSIONThe congenital cytomegalovirus infection could cause the prompt and late-onset hearing loss. The combination of the laboratory evidence with the dynamic hearing screening may contribute to the early detection of hearing loss in infants with congenital cytomegalovirus infection.

OBJECTIVETo collect the data of measuring skin thickness of children of both genders of different ages and parts of body with non-invasive high-frequency ultrasound method.

METHODSTwo hundred and twenty-one children from 1 to 18 years of age,without systemic disease or injury in skin, were enrolled in the study and divided into 4 groups: i.e., infant group (112 years of age), pre-school age group (3-6 years of age), school age group (7-12 years for boys and 7-11 years for girls), adolescent age group (13-18 years for boys and 12-18 years for girls), and each group was subdivided into 2 groups according to the gender. The skin thicknesses of children in cheek, chest, abdomen, forearms, fundament and thigh was respectively measured by 13 MHz high-frequency ultrasound.

RESULTSThe region with thinnest skin in children was the cheek, and the thickest was the back and buttock. (1) There were no significant differences in thickness of skin in the same region between genders and also among different age groups (P > 0.05). (2) There were also no obvious differences of thickness of the dermis and the whole skin in the same region between male and female, or among infants, pre-school age and school age groups (P > 0.05). In adolescent group, the average thickness of dermis in male was (1.16 +/- 0.04 ) - (1.98 +/- 0.47) mm, the average whole thickness of skin in male was (1.27 +/- 0.12) - (2.20 +/- 0.45) mm, while those of female were (1.00 +/- 0.18) - (1.60 +/- 0.30) mm and (1.10 +/- 0.17) - (1.83 +/- 0.29) mm (P < 0.05).

CONCLUSIONIt is reliable to measure the skin thickness by 13MHz ultrasound as a non-invasive method. The main factor which determined the thickness of the skin is dermal thickness, especially in males. The significant differences of skin thickness among cheek, back and buttock provide the basis for us to choose the appropriate thickness of skin grafts harvested from different body parts.

This study was aimed to assess the effect of Astragalus Polysaccharide (ASPS) on in-vitro hematopoiesis. CFU-GM assays were used to determine the effect of ASPS and thrombopoietin (TPO) on granulocytic-monocyte progenitor cells. The CFU assays were also used to investigate the effect of ASPS on the proliferation of HL-60 cells.HL-60 cells were cultured with serum-free RPMI 1640 medium and treated with or without of different concentrations of ASPS. After 72 h incubation, the number of cells were counted.In addition, the caspase-3 and JC-1 expression was determined by flow cytometry with Annexin V/PI double staining. The results showed that ASPS (100, 200 µg/ml) and TPO (100 ng/ml) significantly promoted CFU-GM formation in vitro. Various concentrations of ASPS and TPO also promoted the colony formation of HL-60 cells, the largest effect of ASPS was observed at a concentration of 100 µg/ml. There were no synergistic effects between TPO and ASPS on cellular proliferation. The results also showed that ASPS significantly protected HL-60 cells from apoptosis in condition of serum-free medium culture, suppressed caspase 3 activation, and reduced the cell apoptosis. It is concluded that ASPS can significantly promote the formation of bone marrow CFU-GM and the proliferation of HL-60 cells, the optimal concentration of ASPS is at 100 µg/ml. In the absence of serum inducing apoptosis, ASPS also significantly reduced the apoptosis of HL-60 cells via suppressing the activation of caspase-3.
