ABSTRACT
Objective:To examine differences in metabolic characteristics and metabolites between elderly overweight patients with metabolic syndrome and healthy elderly people, and to identify related factors.Methods:A group of 36 MS patients(the MS group)admitted to The Fourth Central Hospital of Tianjin from April to August 2018 and 43 elderly people(the control group)who underwent physical examination during the same period were included in this prospective study.Serum samples of the patients with metabolic syndrome and elderly healthy controls were collected, and ultra-performance liquid chromatography and quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS)based non-targeted metabolomics was used to search for differences in metabolites between the serum samples of the two groups.The Pearson correlation statistical method was used to find related clinical factors.Results:Comparison of baseline data of the enrolled participants showed that there were statistically significant differences between the two groups in body mass index[(26.9±2.0)kg/m 2vs.(21.7±1.4)kg/m 2], waist circumference, systolic blood pressure, fasting blood glucose, triglycerides and high-density lipoprotein cholesterol( P<0.01). Metabolomics results showed that there were differences in 65 serum metabolites between elderly overweight patients with metabolic syndrome and elderly normal controls, and these differences were enriched in 21 pathways.Correlation analysis showed that waist circumference had the largest number of differential metabolites, followed by body mass index.The major differential metabolites were monosaccharides such as mannose, lyxose and glucose, linolenic acid and its derivatives, and pyroglutamate. Conclusions:Compared with normal elderly people, elderly patients with overweight metabolic syndrome have a variety of differential metabolites, and these metabolites are highly correlated with clinical indicators related to overweight, such as body mass index and waist circumference, and they include monosaccharides, linolenic acid derivatives and amino acids.
ABSTRACT
Objective To investigate the clinical efficacy of levothyroxine replacement therapy in children with hypothyroidism.Methods 45 children with hypothyroidism admitted from Apr.2015 to Dec.2016 were selected as observation group,and 45 healthy children in the same period were selected as the control group.Children in the control group received regular diet and were paid attention to nutritional balance.Children in the observation group were given levothyroxine sodium on the basis of dietary guidance.The two groups were treated continuously for 6 months.The levels of thyroid function,insulin-like growth factor,indicators for growth and development and inflammatory factors were measured before and after treatment in both groups.Results After treatment for 3 months and 6 months,the levels of FT3,FT4,IGF-1,IGFBP-3 and IGF-1/IGFBP-3 in the observation group increased significantly compared with those before treatment,and the levels of TSH in the observation group decreased significantly(P＜0.05).The levels of FT3,lFT4,TSH,IGF-1,IGFBP-3 and IGF-1/IGFBP-3 in the observation group after treatment for 6 months were (7.17±0.06)pmol/L,(2.74±0.07)mU/L,(207.67±9.06)μg/L,(0.46±0.02) mg/L and(34.59±1.97).The difference was not statistically significant (P＞0.05).After 3 months and 6 months of treatment,the height,body weight,osteocalcin and 25-(OH)2D3 levels in the observation group were significantly higher than those in the control group (P＜0.05),and there was no significant difference between the two groups after 6 months (P＞0.05).The difference was statistically significant (P＜0.05).Conclusion Left thyroid hormone replacement therapy can significantly improve the thyroid function of children with hypothyroidism,increase the level of thyroid-associated hormone and insulin-like growth factor,promote the growth and development of children,which is worthy of clinical application.
ABSTRACT
Objective To compare the effects of caffeine citrate and aminophylline combined with naloxone in the treatment of premature infants with apnea.Methods From March 2015 to March 2017,140 premature infants with apnea who were treated in neonatal intensive care unit in Integrated Traditional Chinese and Western Medicine Hospital of Wenzhou were selected in the research.The children were randomly divided into the study group and the control group according to the digital table,with 70 cases in each group.The control group was treated with aminophyl-line combined with naloxone,and the observation group was treated with caffeine citrate.The adverse reaction of children during the treatment was recorded,and the level of apnea was evaluated after treatment.The blood gas index of children before and after 48h treatment was compared,the mortality rate of the children was counted,and the incidence of brain injury during the 1 year follow -up was analyzed.Results After treatment for 48h,the level of PaO2in the two groups was significantly higher [study group: (10.54 ±0.41) kPa,control group: (9.66 ± 0.39) kPa] than those before treatment[study group: (7.18 ±0.26) kPa,control group: (7.21 ±0.24) kPa],and the level of PaCO2[study group: (5.31 ±0.24) kPa,control group: (5.82 ±0.25) kPa]was significantly lower than those before treatment[study group: (6.83 ±0.28) kPa,control group: (6.77 ±0.30) kPa](t＝19.153,13.624,11.271,7.304;P＝0.000,0.000,0.000,0.000),and the level of PaO2in the study group was significantly higher than that in the control group,and the level of PaCO 2in the study group was significantly lower than that in the control group(t＝6.029,4.327;P＝0.000,0.000).The overall effective rate of apnea therapy in the study group (92.86%) was significantly higher than 77.14%in the control group (χ2＝4.509,P＝0.034).The mortality rate(1.43%) and the incidence rate of brain injury (0.00%) of the study group were significantly lower than those of the control group (10.00%and 7.14%)(χ2＝4.773,5.185;P＝0.029,0.023).The incidence rate of adverse reactions (30.00%) of the study group was significantly lower than 50.00%of the control group (χ2＝5.833,P＝0.016).The endometri-al thickness of the study group was significantly lower than that of the control group (P＜0.05).The rate of ovulation success(87.84%) and pregnancy success rate (45.94%) of the study group were significantly higher than those of the control group(72.97%and 28.39%)(χ2＝5.189,4.890;P＝0.023,0.027).The rate of abortion(8.82%) of the study group was significantly lower than 33.33%of the control group (χ2＝5.242,P＝0.022).During the period of treatment,the incidence rate of adverse drug reactions (6.77%) of the study group was not significantly different from 8.11%of the control group (χ2＝0.098,P＝0.754).Conclusion Compared with aminophylline combined with naloxone treatment,caffeine citrate can significantly improve the blood gas status of apnea preterm infants,improve the overall curative effect of apnea,prevent the occurrence of neonatal death and brain injury,and reduce the adverse reactions of the children during the treatment.It is worthy of clinical application.
ABSTRACT
Objective To investigate the role of sLOX?1 and leptin in metabolic syndrome ,glucose and lipid metabolism. Methods 58 patients with metabolic syndrome were included in the study ,with other 35 normal controls as control group. Fasting venous blood samples were collected. ELISA method was used to detect serum sLOX?1 and leptin levels. The related biochemical indicators were tested. Results The sLOX?1 and leptin levels in the metabolic syndrome group were significantly higher than those in the control group(P 0.05). sLOX?1 and leptin levels were positively correlated. They were positively correlated with WAIST,TG,SBP,DBP,and negatively correlated with HDL?C. Leptin and age,FPG also had positive correlation,but sLOX?1 was not correlated with age and FPG. Conclusion sLOX?1 may be able to predict endothelial damage in patients with metabolic syndrome in an early stage. Combined with leptin ,the endothelial dysfunction could be reflected more accurately. They may be the important factors for early diagnosis and risk assessment of metabolic syndrome.
ABSTRACT
Objective To investigate the development of tidal breathing lung function in very low birth weight infants with bronchopulmonary dysplasia(BDP).Methods Two hundred and sixty-two very low birth weight infants hospitalized in Wenzhou Children′s Hospital were enrolled as objects.All infants were given the tidal breathing pulmonary function test within a week before discharge and at the corrected age of 6 to 8 months.According to clinical diagnosis,they were divided into BPD group(n=65) and non-BPD group(n=197),and BPD group were divided into mild group(n=31),moderate group(n=20) and severe group(n=14) according to the severity.The lung function indexes were compared between different groups.Results The results of the test within a week before discharge displayed that the respiratory rates in the BPD groups were higher than those in the non-BPD group(all P＜0.05).The peak expiratory flow(TPEF),tidal expiratory flow at 75%,50%,and 25% tidal volume(TEF75,TEF50,TEF25) in moderate to severe BPD group were higher than those in other groups(all P＜0.05),while in mild BPD group were higher than those in non-BPD group(all P＜0.05).The ratio of time to peak tidal expiratory flow to total expiratory time (TPEF/TE),ratio of volume to peak tidal expiratory flow to total expiratory volume (VPEF/VE) were lower in BPD group than those in non-BPD group,the decline was more obvious as the BPD was more serious(all P＜0.05).No significant differences were found between groups in tidal volume(P＞0.05).The result at the corrected age of 6 to 8 months displayed that TPEF,TEF75,TEF50,TEF25 in severe BPD group were still higher than those in any other group(all P＜0.05),while TPEF/TE,VPEF/VE were lower than those in any other group(all P＜0.05),no significant differences were found between other groups in other indicators(P＞0.05).Conclusion Preterm infants BPD have different degrees of lung injury,but as the age grows some lung function indexes can improve gradually(at the corrected age of 6 to 8 months).However,early severe small airway obstruction is still serious.Therefore,it′s important to prevent and treat BPD for the prevention and regulation of respiratory tract disease in future.
