OBJECTIVETo investigate the prevalence of anemia and related risk factors in infants aged 6-12 months from rural areas of southern Shaanxi Province.

METHODSA questionnaire survey was used to collect the basic information on infants aged 6-12 months and their families from rural areas of southern Shaanxi Province, China. The content of hemoglobin was measured in these infants. A multivariate logistic stepwise regression analysis was performed to determine the risk factors for the development of anemia in infants.

RESULTSA total of 1 802 infants and their families participated in the survey, and there were 1 770 valid samples. A total of 865 infants (865/1 770, 48.87%) were found to have anemia. The multivariate logistic stepwise regression analysis showed that breastfeeding after birth (lack of scientific supplementary food) increased the risk of anemia in infants (OR=1.768, P<0.01). Addition of supplementary food which met the criteria for minimum feeding frequency recommended by WHO (OR=0.779, P<0.05) and formula milk feeding (OR=0.658, P<0.01) were protective factors against anemia in infants.

CONCLUSIONSIn the rural areas in southern Shaanxi Province, anemia in infants aged 6-12 months is still a serious public health problem. Improper feeding can increase the risk of anemia in infants, and scientific addition of supplementary food is the key to reducing anemia in infants.

OBJECTIVEUsing doubly labeled water method to validate the colmputer science application's activity monitor (CSA) in assessing physical activity of free-living adults in Beijing, in order to develop equations to predict total daily energy expenditure (TEE) and activity related energy expenditure (AEE) from activity counts (AC) and anthropometric variables.

METHODSA total of 72 healthy adults (33 males and 39 females, mean age 43.6 +/- 4.0 yr) were monitored for 7 consecutive days by CSA. TEE was simultaneously measured using doubly labeled water method. Average AC (counts/min(-1)) was compared with TEE, AEE and physical activity level (PAL).

RESULTSPhysical activity determined by AC was significantly related to data on energy expenditures: TEE (r = 0.31, P < 0.01), AEE (r = 0.30, P < 0.05), and PAL (r = 0.26, P < 0.05). Multiple stepwise regression analysis showed that TEE was significantly influenced by gender, fat-free mass (FFM) or BMI and AC (R(2) = 0.52 - 0.70) while AEE was significantly influenced by gender, FFM and AC (R(2) = 0.25 - 0.32).

CONCLUSIONAC from CSA activity monitor seemed a useful measure in studying the total amount of physical activity in free-living adults while AC significantly contributed to the explained variation in TEE and AEE.

OBJECTIVETo investigate the epidemiological characteristics of human papillomavirus (HPV) infection in men attending a sexually transmitted diseases (STD) clinic in Hangzhou area.

METHODSMale subjects (n=375) aged 18-70 years, attending the STD clinic were recruited. Urethral swabs were assessed for HPV DNA using polymerase chain reaction (PCR) with the consensus primers MY09/11. HPV genotypes of positive PCR products were determined by restriction fragment length polymorphisms and direct sequence analysis.

RESULTSOf the 375 swabs collected, 305 (81.3%) yielded sufficient DNA for the subsequent HPV analysis. Among the 305 subjects, the prevalence of HPV was 13.8%. Nononcogenic HPV types were found in 8.5% (26/305) of subjects, oncogenic types in 4.3% (13/305), and multiple types in 1.0% (3/305). The prevalence of HPV infection was higher in subjects from urban area than in those from rural area (P < 0.05). The prevalence was also higher in those who received fewer years of education (P < 0.05) and those who had more sex partners (P < 0.05).

CONCLUSIONSHPV infection among men at high risk is not uncommon. The detection rate of HPV DNA is significantly related to some sociodemographic factors, such as residence, educational level and the number of sex partners.

OBJECTIVETo study the diagnosis and treatment of persistent hyperinsulinemic hypoglycemia of infancy.

METHODSThe clinical data of 12 infants with persistent hyperinsulinemic hypoglycemia were retrospectively reviewed.

RESULTSConvulsion, cyanosis, lethargy, refusing milk sucking, irritability and sweating were common symptoms. The laboratory findings displayed persistent hypoglycemia and hyperinsulinism in all of the 12 infants. The glucagon test showed positive and no urine ketones were detected in all of the 12 infants. Seven infants were treated with oral diazoxide (5-15 mg/kg daily) and 4 infants showed effective to the therapy. One patient was given subtotal pancreatectomy and the blood glucose level was restored to normal after operation. Of the 12 infants, 6 presented psychomotor retardation in a follow-up of 2 months to 67 months, 3 had loss to follow-up and 3 were still in a follow-up.

CONCLUSIONSThe measurement of blood glucose, blood insulin and urinary ketons is helpful in the diagnosis of persistent hyperinsulinemic hypoglycemia of infancy. Diazoxide therapy is effective in some of patients.

OBJECTIVETo probe the effects of long-term oral administration of lanthanum nitrate [La(NO(3))(3)] on morphological change in the liver, aftereffect of deposited La in the liver and their mechanism in rats.

METHODSYoung Wistar rats were divided into two groups, one fed with 0.1, 0.2, 2.0, 10.0 and 20.0 mg/kg of La(NO(3))(3) for six months and the other for the control. Changes in ratio of liver to body weight were observed after exposure to La(NO(3))(3) at varied doses for six months and one month after six-month exposure, as well as morphology of the liver in the rats with routine histochemistry and transmission electron microscopy (TEM) technique. Content of La in the liver was measured with inductively coupled plasma-mass spectrometry (ICP-MS).

RESULTSRatio of liver to body weight was significantly higher in the male rats exposed to 20.0 mg/kg of lanthanum for six months than that in the control group. Ratio of liver to body weight restored to normal in the rats exposed to 20.0 mg/kg of La one month after six-month exposure. Infiltration of inflammatory cells in the portal region of the liver, small amount of fat drops in hepatocytic cytoplasm, increased density of mitochondria stroma, lysosome containing highly-electronic-density bodies and dense granules, normal nucleus and slightly deformed nucleus of hepatocytes could be found in the rats exposed to 20.0 mg/kg. Areas of the liver deposited with glycogen after six-month exposure to 20.0 mg/kg of La accounted for (26.1 +/- 1.5)% and (4.1 +/- 1.4)%, respectively for male and female rats, significantly lower than those in the control group [(31.3 +/- 1.4)% and (39.4 +/- 0.9)%, respectively], with a statistical significance and very statistical significance, respectively. There was a little infiltration of inflammatory cells in the portal region of the liver one month after six-month exposure to 20.0 mg/kg of La, and amount of the dense bodies was lower in the rats exposed to La for six months. Liver contents of La in the rats of all experimental groups were lower one month after six-month exposure than those in the rats exposed for six months.

CONCLUSIONSExposure to a dose of 20.0 mg/kg La(NO(3))(3) for a long term could damage the liver structure to certain extent, but lanthanum deposited in the liver could be eliminated from the body gradually.

OBJECTIVETo probe into effects of acupuncture on rehabilitation of nervous functions in the stroke patient of different OCSP types.

METHODSThe stroke patients were randomly divided into 4 subtypes (LACI, TACI, PACI, POCI) based on the OCSP clinical classification. The patients of every subtype were randomly sub-divided into an observation group and a control group. The patients in the 2 groups were treated with routine western medicine, and acupuncture at Baihui (GV 20), Sanyinjiao (SP 6), Taixi (KI 3), Xuehai (SP 10), etc. were added with reinforcing and reducing manipulation in the observation group and without manipulation of the needle in the control group. They were assessed with daily living ability scale (BI) at the time of enrollment, the end of 1, 3, 6, 12 months after the stroke, respectively.

RESULTSThere was no significant difference between the two groups for BI in LACI (P>0.05); there were significant differences 3, 6 and 12 months after the stroke between the two groups in PACI, POCI (P<0.05); in the TACI, there was a significant difference between the two groups for BI 3 and 6 months after stroke (P<0.05), with no significant difference 12 months after stroke (P>0.05).

CONCLUSIONAcupuncture has different effects on rehabilitation of daily living function in the stroke patient of different OCSP types.
