Effect of cultivation substrate on growth and active component contents of Anoectochilus roburghii from three different origins / 中国中药杂志

Three different origins of Anoectochilus roburghii were used as experimental materials to study the effect of three different substrate( peat soil-river sand-peanut shell) radio on survival rate,plant height,stem diameter,plant fresh weight,root number,the longest root length,root diameter,and the contents of polysaccharide,flavonoids,and polyphenol. The results showed that when the substrate ratio was 4 ∶2 ∶2,the survival rate of A. roburghii from different origins was the highest,and the plant height,stem diameter,plant fresh weight,the longest root length and root diameter were also the largest. The cultivation substrate had no significant effect on the polysaccharide content of A. roxburghii and A. formosanus. When the substrate ratio was 4 ∶ 2 ∶ 2,the polysaccharide content of A.chapaensis was significantly lower than that of the other two combinations. When the substrate ratio was 4 ∶2 ∶1,the flavonoid content of A. formosanus was higher than that of the other two combinations. When the substrate ratio was 4 ∶2 ∶2,A. formosanus and A. chapaensis had higher polyphenol content.

Impact of Simulated Warming on Growthand Floral Characteristics of Two Varieties of Medicinal Epimedium

ABSTRACT An open top chamber (OTC) warming system was established in natural field conditions to study the impact of simulated warming on growth and floral characteristics of E. wushanense and E. acuminatum. Results: plant height and leaf growth were affected significantly.In +2°C warming condition, increment of plant height, leaf length and width and daily mean incrementof the two varieties were significantly greater than those of the control group; however, in warming +5°C condition, the increments were significantly lower than those of the control group. Floral differentiation was presented when different treatment was adopted. Floral quantitative character of E. acuminatum increased markedly after +2°C warming, but declined markedly after +5°C warming; however, floral quantitative characters of E. wushanense declined after +2°C and +5°C warming. The results can be used as a reference for cultivation and introduction of the two varieties.

Investigation on long-term complications of glucocorticoid in treatment of Diamond-Blackfan anemia / 中华实用儿科临床杂志

Objective To collect and summarize long-term complications of glucocorticoid (GC) in treatment of Diamond-Blackfan anemia (DBA).Methods A total of 17 DBA patients,treated with GC more than 1 year from December 2009 to November 2012 in Being Children's Hospital,Capital Medical University,were retrospectively investigated.The data of general information,drug treatment,treatment response,height and body mass in different therapy periods,and therapy related adverse reaction were collected.The data entry and the statistical analysis were performed using SPSS 16.0 software.Results Seventeen cases which fulfilled the research criteria were enrolled.The 58.8 percent of cases (10/17) began GC therapy from the age younger than 6 months.The 76.4 percent of the cases (14/17) started prednisone therapy with the dosage ≥2 mg/(kg · d),and the median time of maintenance therapy with this dosage was 2 months (1-5 months).The median time of prednisone dosage greater than 0.5 mg/(kg · d) was 6 months (3-48 months).Patients were divided into 2 groups at the beginning of therapy according to whether their age was younger or older than 6 months.The median height of younger age group was-1.0 SD (-3.5-1.0 SD) of corresponded age-sex-standard height at the beginning of prednisone therapy,and was dropped to-3.5 SD (-3.5--2.0SD)afterhalfyeartreatment.For older age group,it was0.0 SD(-1.5-2.0 SD)and-0.5 SD (-1.5-0.5 SD) respectively.During the therapy,there were 1 fracture,2 measles pneumonia,3 pneumonia,3 hirsuitisms,5 thrushes,and 12 central obesity cases.Conclusions GC related adverse reaction might appear when applying prednisone for the treatment of DBA in long term.It was suggested that GC therapy should start after 6 months old if possible,and the duration of 0.5 mg/(kg · d) GC treatment should be reduced as short as possible.

Extraction And Non Extraction - An Overview.

Every orthodontists often appear to have conflicting treatment plans for the same patient. The reason is not that they see very different problems or have radically different philosophies of treatment, but rather that each doctor has a different line in the gray area between extractions and nonextraction. Two treatment plans that appear very different can both be based on a similar analysis of the patient’s problem, but end up with very different treatments due to the black and white nature of the decision making process.It is important to understand that in borderline cases there are no correct or right answers. Both treatments performed by competent orthodontists would produce a good result, but neither is perfect. Each option would have pros and cons, and orthodontists and dentists could (and do) spend endless amounts of time debating which option is “right”.

Breastfeeding Practices and Nutritional Status of Orang Asli Children (Temuan and Mah Meri) in Sepang District and Carey Island, Selangor

Objectives: There is a lack of current published information on health and nutritional status of Orang Asli children. A study was conducted to assess breastfeeding practices, dietary intake and growth status of Orang Asli children in Sepang and Carey Island, Selangor.Methods: A total of 173 children(88 Temuan and 85 Mah Meri) from 137 households were measured for body weight and height. Information on breastfeeding practices and dietary intake was obtained from their mothers. Results:Most of the mothers (98.9%) breastfed their infants with a high proportion (86.8%) initiating breastfeeding within one hour after delivery.About 53% of the mothers reported discarding colostrum due to various reasons including the perception that colostrum in undesirable and can produce ill-health. Although many of these mothers (58.3%) discarded colostrum on their own initiative, about 25% of them reported that they were advised by health professionals. Among mothers who had stopped breastfeeding at the time of the study (n=48), the mean duration of breastfeeding was 12.1 ± 8.9 months. About 33% of the mothers stopped breastfeeding before their infants were 6 months old and only 31% breastfed their children for more than 1 year. The percentages of significantly underweight, stunted and wasted were 48.9%, 5.2.2% and 4.3% respectively for children aged 1-3 years, whereas among children aged 4-6 years old, 35.8%, 50.6% and 1.3% were underweight, stunted and wasted, respectively. A higher proportion of Mah Meri than Temuan children in both age groups were significantly underweight, stunted and wasted. Despite the adequate intake of energy and most nutrients,the Orang Asli children had insufficient mean number of servings for all food groups-grain and cereals, fruits, vegetables, meat and fish, and milk and dairy products. Conclusion: In this study, undernutrition is a major health and nutrition problem among the Orang Asli children. The problem could be due to many factors that include poor infant and child feeding practices. Concerted efforts by various government and non government agencies are essential to improve the health and nutrition of Orang Asli.

Growth Status of Very Low Birth Weight Infants / 대한소아내분비학회지

PURPOSE: With the advancement of perinatal care, the survival rate of very low birth weight(VLBW) infants has been increasing. Therefore, the outcome of postnatal growth status needs to be studied. The purpose of this study was to compare the postnatal growth status and the related factors in order to determine the incidence of catch-up growth. METHODS: This study was carried out with the 86 children(1-8.9 yrs, mean age 4.2+/-2.2 yrs, 43 males and 43 females) born in VLBW infants at Inje University Sannggye Paik Hospital, from September 1989 to August 1998. Mean gestational age was 30.3+/-2.5weeks, mean birth weight was 1,281+/-171g and mean birth height was 39.0+/-2.2cm. RESULTS: 1)Mean height standard deviation score was -1.14+/-1.28. Mean weight standard deviation score was -0.20+/-1.35. 2)Of the entire study group of the 86 children, 6 children(7%) were below -2 in height SDS and 5 children(6%) were below -2 in weight SDS. 3)Height SDS correlated with birth weight(r=0.26, P<0.05) and midparental height(r=0.26, P<0.05). Height SDS was not correlated with gestational age and birth height. 4)There were no significant difference of height SDS and weight SDS between high-dose dexamethasone treated group by bronchopulmonary dysplasia and untreated group. CONCLUSION: Height SDS and weight SDS increased by the age. Current height SDS was significantly correlated with birth weight and midparental height. To clarify the factors that influence the growth status of VLBW infants, further longitudinal studies with more patients will be needed.

The Growth Hormone Levels and the Effect of Growth Hormone in the Children with Chronic Renal Failure / 대한소아내분비학회지

PURPOSE:Growth retardation is a serious clinical problem in children with chronic renal failure(CRF). Dialysis and renal transplantation do not provide an improvement in growth velocity. Possible causes of growth retardation are nutritional deficiency, electrolyte imbalance, uremia, renal asteodystrophy and chronic anemia. However, catch-up growth cannot be achieved after correcting these factors. There is no concordance about disturbances of growth hormone(GH)-insulin-like growth factor-I (IGF-I) axis. in CRF. This study was designed to evaluate the growth status, IGF-I, GH and the effect of GH in CRF. METHODS:Twelve children with CRF(five were treated conservative, seven were transplanted) were included. IGF-I, stimulated GH, 24 hour integrated concentration of GH (IC-GH)were measured. Six were given rhGH(0.1U/kg/day) for average one year. RESULTS: 1)Growth velocity(GV) was 3.2+/-0.8cm/yr(conservative therapy:3.3+/-0.7, transplanted:2.9+/-0.8). Height standard deveation score(SDS) was -2.4+/-1.3cm/yr(conservative therapy group:-3.3+/-1.4, transplanted group:-1.3+/-0.4). Bone age lagged 2.1+/-13yr behind chronological age. 2) IGF-I concentrations were normal. 3)Stimulated GH levels were normal(16.6+/-3.3ng/ml) except one patient. Twenty- four hour IC-GH were less than 3.2ng/ml in 4 patients. 4)After GH therapy, GV increased 3.3+/-0.7cm/yr to 5.4+/-0.8cm/yr and Ht SDS increased -3.3+/-1.4 to -2.9+/-1.5 in the conservatively treated group. GV increased 2.9+/-0.8cm/yr to 5.5+/-1.8cm/yr and Ht SDS increased -1.3+/-0.4 to -0.8+/-0.5 in the transplanted group. CONCLUSION: Stimulated GH was normal but spontaneous secretion of GH was decreased in some patients with CRF. This neurosecretory dysfunction may be one causative factor in CRF. For these patients GH replacement therapy will be effective in promoting growth.

Growth Status and Levels of Growth Factors in Children with Insulin-dependent Diabetes Mellitus

PURPOSE: It is well known that the linear growth velocity in children with insulin-dependent diabetes mellitus (type 1 DM) is closely related to metabolic control and onset age of the disease. Many studies have demonstrated growth impairment in children with type 1 DM, regardless of the degree of metabolic control, whereas other studies have found no growth retardation. Therefore, we examined the growth status and the level of growth factors in children with type 1 DM, and compared them with healthy children. METHODS: Thirty-six patients with type 1 DM (21 female, 15 male; mean age, 10.8 years : range, 5-15 years)were studied. The mean duration of type 1 DM in these patients was 2.7 years (range, 0.1-7.0 years). Their growth status in height standard deviation score (HTSDS) and levels of insulin-like growth factor (IGF)-I, free IGF-I, IGF-II and IGF-binding protein (IGFBP)-3 were compared with age and sex matched normal children (21 female, 15 male; mean age, 10.3 years; range, 5-15 years). RESULTS: As HTSDS in type 1 DM, children were 0.4 +/- 1.1, no prominent growth impairment was observed in type 1 DM children. IGF-I and IGF-II levels decreased significantly in type 1 DM, but no significant differences in free IGF-I and IGFBP-3 levels compared to normal. Height in type 1 DM children was in direct correlation with free IGF-I (r=0.35, P<0.05) and IGFBP-3 (r= 0.45, P<0.01), respectively. CONCLUSION: This study reveals that the levels of IGF-I and -II are decreased in children with type 1 DM, whereas free IGF-I levels are not. These findings may be related to the decreased IGFBP-3 levels in diabetic children, and may explain no growth impairment, except in cases of extremely poor metabolic control.
