ABSTRACT
Objective To investigate the clinical effect of noninvasive mechanical ventilation in the treatment of chronic obstructive pulmonary disease (COPD) and the expression of insulin-like growth factor (IGF) Ⅰ, Ⅱand cathepsin B (CB) in patients.Methods 89 patients with chronic obstructive pulmonary disease from January2014 to June 2017 in the hospital for treatment were retrospectively chosen as the research objects. They were randomly divided into the control group (n = 43) and the study group (n = 46). The control group was treated with conventional therapy. The study group was treated with noninvasive mechanical ventilation on the basis of the control group. The observation period was 10 days of treatment, the level of the indicators of lung function, arterial blood gas changes of the both groups were detected, and the clinical treatment efficiency was taken for statistics. At the same time, the levels of IGF-Ⅰ, Ⅱ and CB in patients were analyzed.Results (1) The lung function of the study group: the lung function VC [ (302.72 ± 40.79) m L], the maximum expiratory flow PEF (421.72 ± 37.59) L/min], and the first expiratory volume FEV1 [ (83.24 ± 11.65) ％], were significantly higher than that of the control group (P＜0.05). (2) The arterial blood gas in the study group: arterial oxygen partial pressure (PaO2) [ (99.24 ± 10.16) mm Hg], partial pressure of carbon dioxide (PaCO2) [ (43.32 ± 5.37) mm Hg], oxygenation index (PaO2/FiO2) [ (281.02 ± 19.74) ％ ], were better than the level of detection in the control group (P＜0.05). (3) The effective rate of clinical treatment was 93.48％ in the study group, which was significantly higher than that in the control group of 67.44％ (P＜0.05). (4) The IGF-Ⅰ [ (11.47 ± 1.53) ug/L] and IGF-Ⅱ [ (28.27± 11.49) ug/L] in the study group were lower than those in the control group, while CB [ (1.03 ± 0.24) ng/ml]was higher than that of the control group (P＜0.05).Conclusions Noninvasive mechanical ventilation is helpful to clear the recovery of lung function in patients with chronic obstructive pulmonary disease, can alter the abnormal expression of insulin-like growth factor I, II and cathepsin B levels in patients, and the clinical treatment effect is significant.
ABSTRACT
Objective:To explore the levels of serum adiponectin,insulin growth factor Ⅰ (IGF-Ⅰ) and prealbumin in preterm infants,and analyze their correlation with preterm EUGR infant.Methods:321 cases of preterm infants who were born in our hospital and transferred to neonatal department in 24 hours from January,2014 to January,2016 were enrolled in the present study.According to the weight at discharge,they were divided into the EUGR group and the non EUGR group,the growth and development as well as the levels of serum adiponectin,IGF-Ⅰ and PA in the two groups were compared.Results:The occurrence rate of EUGR was 55.76％ (179/321) in the 321 cases ofpreterm infants;the weight of EUGR group was significantly lower than that of the non EUGR group at 42 th days and three months after birth(p＜0.05).The SDS of both groups were all negative,and that of EUGR group was significantly lower than non EUGR group (p＜0.05).The levels of serum adiponectin,IGF-Ⅰ and PA of both groups were significantly lower than the control group at seventh days of birth,and the PA level of EUGR group was significantly lower than non EUGR group (p＜0.05).There was no significant difference in the serum adiponectin and PA levels between 7 days and 14 days in EUGR group (P ＞ 0.05),however,the serum adiponectin and PA levels in the non EUGR group was obviously increased and significantly higher than that of the EUGR group (p ＜ 0.05).The level of IGF-Ⅰ in both groups keep unchanged during two weeks (P＞0.05).Conclusion:The lower levels of serum adiponectin,IGF-Ⅰ and PA were closely related to the EUGR of preterm infants,which could be used as biochemical indexes to early diagnosis of EUGR.
ABSTRACT
The changes in hypothalamic-pituitary function in older people include the effects of aging per se on hypothalamic-pituitary physiology,such as age-related declines in GH-IFG-1 system and increased activity in CRH-ACTH axis,and the hormone hyposecretion due to anterior pituitary diseases in elderly,including fibrosis and vascular alterations.In considering changes in hypothalamic-pituitary function in older people,it is important to distinguish between what is age-related and what is disease-related.Symptoms associated with hypopituitarism are nonspecific and may be often attributed to normal aging and can be challenging in clinical practice.Furthermore,the benefits and safety of selective pituitary hormonal replacement,including growth hormone replacement,remain controversial in the elderly.The evidence for age-related changes in GH-IGF-1 system and CRH-ACTH axis and their clinical consequences are reviewed.The characteristics in the clinical approach to disease-related hypopituitarism in older person are also briefly discussed.
ABSTRACT
Objective To explore the effects of Tangzhiping granules on the blood glucose and IGF-Ⅰ in T2DM rats.Methods 40 SPF grade Wistar rats whose weight were about (200±20)g were selected as the subjects for this study,one half were male and another half were female.After be adapted to the normal food for 1 week,8 rats were selected randomly from all of rats following their weight as the blank group (ordinary feed).The remaining the others were fed with the high-fat and high-sugar food.The 6th week,the other rats would be undergo intraperitoneal injection once in left lower belly with 40 mg/kg streptozotocin (STZ),and enable them to become T2DM rats.The 8th week,we would select successful animal models 32 which were divided randomly into a modle group,a Tangmaikang (TMK) granules group,a Tangzhiping granules (TZP)group.The 12th week,we would execute all of rats and collect the blood serums which were tested for the blood glucose and IGF-Ⅰ.Results () Compared model group with blank group,the levels of the blood glucose of the model group increased to (28.33±0.50)mmol/L,while the IGF-Ⅰ decreased to (3.40 ± 0.83) pg/ml,which showed the model of type 2 diabetic rats was successfully set up.② The levels of the blood glucose of the Tangzhiping granules group and Tangmaikang granules group were lower than that of the model group to (15.06±0.39)mm ol/L,(20.12±0.58)mmol/L,but the levels of the IGF-Ⅰ were higher to (9.39±2.91)pg/ml,(5.58± 1.09)pg/ml,which implied that each group of pharmacological treatment had a good effect.③ The level of the blood glucose and IGF-Ⅰ of the Tangzhiping granules group was also significantly different from that of the Tangmaikang granule group,the therapeutic effect of Tangzhiping granules group was better than that of Tangmaikang granules group.Conclusion Tangzhiping granules can reduce the blood glucose of T2DM rats.And also can increase IGF-Ⅰ of T2DM rats.Tangzhiping granules can improve the various symptoms of diabetes mellitus at the same time.
ABSTRACT
Objective To evaluate the safeness of this treatment by comparing the serum IGF-Ⅰ and IGFBP3 concentration level before and after receiving rhGH treatment in pediatric patients.Methods 30 pediatric patients in our hospital receiving rhGH treatment were subjected to monitor serum IGF-Ⅰ and IGFBP3 level before and after the treatment and calculate the IGF-Ⅰ and IGFBP3 ratio.At the same time the serum T3,T4 and TSH are also assayed.Results The average increase of booly heights was(8.77?3.01)cm /y(t=7.773,P0.05),but the serum IGFBP3(t=3.759,P0.05).However,there was statistical significance of the serum IGFBP3 level between subgroups(f=22.964 P0.05).Conclusion The serum IGF-Ⅰ and IGFBP3 level are able to be used as one of clinical evaluation benchmarks to detect the risks of inducing tumor during the rhGH treatment in the pediatric patients.
ABSTRACT
[Objective]To demonstrate mechanism of ESW in curing osteogetic disorders,we studied expression of some osteogenetic factors in human mesenchymal stem cells(hMSCs)when exposed to ESW.[Method]After success in marrow aspiration,isolation and obtainment optimal experimental energy,a dose of 5kV and 100 times of ESW was applied to hMSCs of passage 1.The expression of IGF-Ⅰ and TGF-?1 were examined by immunocytochemical staining.[Result]The cytochemical staining results showed that expression of IGF-Ⅰ and TGF-?1 appeared at different passage of hMSCs after ESW intervention.Appearance of IGF-Ⅰ was earlier than TGF-?1 which didnt express until passage 7.At the same interval,the expression of IGF-Ⅰ and TGF-?1 in control group difference is lower than ESW group,respectively(P
ABSTRACT
Insulin-like growth factorⅠ(IGF-Ⅰ) is essential for the growth and differentiation of hair follicles which is an important part of wool and cashmere.But there is no report on polymorphisms of the IGF-Ⅰ gene in cashmere goat,and also few candidate genes for cashmere production traits have been reported in cashmere goats.The objectives of this work were to detect the single nucleotide polymorphism(SNP) in the 5' flanking region of IGF-Ⅰ gene and to determine their association with fibre traits in Liaoning cashmere goats.The fibre traits data investigated in the experiment were combed cashmere weight,cashmere fibre length and cashmere fibre diameter.A few individuals of the Liaoning cashmere goats,selected according to phenotypic character,were used for SNPs detection in the 5'flanking region of IGF-Ⅰ gene,and four point mutation G→C(388 bp),A→G(668 bp),A→ C(719 bp),G→A(752 bp) were identified,which result in a CdxA bonding-site lack,and score increase of C/EBP site in the 5' flanking region compared with the wild type.Then different genotypes were detected in 520 Liaoning cashmere goats using create restriction site(CRS) and polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP),three genotypes,AA,AB and BB were observed coded for by two different alleles A and B for each SNP,and 13 diplotypes were identified in the groups of the four SNPs.The relationships between the genotypes and combed cashmere weight,cashmere fibre length and cashmere fibre diameter were analyzed.The statistical analysis showed that animals with the genotype AA of SNP2 in Liaoning cashmere goats had the thinnest cashmere fiber diameter compared with those with the AB and BB genotype(P
ABSTRACT
Bone morphogenetic proteins (BMPs) play a pivotal role in the formation,induction and repair of the bone; BMPs have been confirmed to induce bone formation.Transforming growth factor-beta,insulin-like growth factor-Ⅰ and basic fibroblast growth factor also contribute to bone formation; combination of the factors with BMPs can promote the healing of fracture and non-union,which may have a bright future in orthopedics.
