In this study, a knowledge base of medical examination information was built through the investigation of general hospital, and all examination systems and items were integrated into the appointment register platform, so that all examinations were appointed based on the principle of completing all tests in the shortest time, thus building a unified intelligent appointment register platform for the hospital. From that, the average appointment register procedure of examinations has been shorten after launching the intelligent platform, labor costs of appointment register center and inpatient legwork have been saved, all examinations of inpatients can be finished in 48 hours, and patient satisfaction has been improved obviously.
ABSTRACT
OBJECTIVE: To investigate the protective effects of rhubarb and licorice( Rhubarb licorice root decoction) on liver and kidney injury in rats exposed to cadmium. METHODS: Healthy male specific pathogen-free grade SD rats were randomly divided into control group,model group,licorice group and Rhubarb licorice root decoction group by random number table. Except the control group,the other 3 groups were intraperitoneally injected with 1. 00 g/L cadmium chloride solution at the dose of 1 mg/kg body mass,once every other day for 6 times. After 7 days,the rats in the licorice group and the Rhubarb licorice root decoction were given licorice soup and Rhubarb licorice root decoction,respectively. The dose was 50 mg/kg body mass,once per day for 30 days. At 24 hours after the last gavage,rats were secrificed and the liver and kidney were isolated. Liver and kidney organ coefficients were calculated and the pathologic changes in liver and kidney tissues were observed. The fully automatic biochemical analyser was conducted to detect the activity of aspartate aminotransferase( AST) and alanine aminotransferase( ALT) in liver tissue and the activity of superoxide dismutase( SOD) and level of malondialdehyde( MDA) in liver and kidney tissues. RESULTS: Large area of necrosis were found in the liver and kidney in the model group. In the ticorice group and Rhubarb licorice root decoction group,the necrosis in the liver and kidney decreased,and Rhubarb licorice root decoction group improved more obviously than ticorice group.The coefficient of liver and kidney,the activity of AST and ALT in liver tissue,and MDA level in liver and kidney tissues of the model group increased( P < 0. 05),meanwhile the activity of SOD in liver and kidney tissues decreased( P < 0. 05)when compared with the control group. The above indexes in licorice group and Rhubarb licorice root decoction group had improvement than that of model group( P < 0. 05). The improvement of above indexes in the Rhubarb licorice root decoction group was better than that in the licorice group( P < 0. 05). CONCLUSION: Rhubarb licorice root decoction has protective effect on liver and kidney damage caused by cadmium exposure.
ABSTRACT
Objective To analyze the prevalence characteristics of fatty liver in young and middle-aged people,and to explore the risk factors of the disease,so as to provide clinical evidence for the prevention and treatment of fatty liver.Methods In 756 young and middle-aged healthy subjects with age≤50 years old,there were 197 fatty liver cases were diagnosed by ultrasonic test during 2015 year.The prevalence of different characteristics in young and middle-aged fatty liver was analyzed,the difference of blood biochemical index between fatty liver and non fatty liver group was compared,and risk factors of fatty liver was explored by binary logistic regression model.Results The total prevalence rate of fatty liver in young and middle-aged people was 26.1%(197/756),among which 33.1% (119/359) were male and 19.6%(78/397) were female,the prevalence rate of male was significantly higher than that of female(χ2=17.833,P<0.05).The prevalence rate of fatty liver increased with age(χ2=33.296,P<0.05),which in 40-50 years old was 37.1%(111/299) and significantly higher than that in 20 years-(15.0%)(24/160) and 30 years-(20.9%)(62/297).Logistic regression analysis on influencing factors of fatty liver prevalence showed that age,sex,body mass index(BMI),drinking,diabetes and fasting blood glucose(FPG),triglyceride(TG),total cholesterol(TC) were closely related to fatty liver(P<0.05),overweight,obesity,drinking,diabetes increased the risk of fatty liver disease.Biochemical indicators(FPG,TG,TC) in fatty liver group were higher than those in non fatty liver group((7.09±1.47) mmol/L vs.(5.14±1.71) mmol/L,(5.98±1.23) mmol/L vs.(4.95±1.42) mmol/L,(2.03±0.45) mmol/L vs.(1.23±0.67) mmol/L,t=271.905,98.866,278.255;P<0.05).Conclusion The prevalence rate of fatty liver in young and middle-aged people is high,and controlling body weight,give up drinking,active treating diabetes,reducing blood glucose and blood lipids can effectively decrease the prevalence of fatty liver in young and middle-aged people.
ABSTRACT
Objective To study the changes of serum markers of hepatic fibrosis in patients with fatty liver,and to provide clinical diagnosis and treatment for patients with fatty liver.Methods Three hundred and sixty-one patients with fatty liver were divided into light,medium and heavy three degrees according to the intrahepatic echo and structure.Serum markers of hepatic fibrosis-hyaluronic acid (HA),laminin (LN),procollagen Ⅲ (PC Ⅲ) and type Ⅳ collagen (C-Ⅳ) were examined by enzyme linked immunosorbent assay (ELISA),and the ordinal logistic regression model was used to analyze,regarding the grade of fatty liver as dependent variable.Results The levels of serum fibrosis markers HA,LN,PC Ⅲ and C-Ⅳ in patients with mild,moderate and severe fatty liver were (94.53 ± 16.21),(101.38 ± 20.42),(127.34 ± 26.54) μg/L,(107.25±22.63),(117.38±24.84),(136.62±32.27) μg/L,(110.27±23.15),(121.55±27.36),(138.62± 30.62) μg/L,(72.61 ± 15.46),(82.06 ± 18.28),(92.96 ± 21.35) μg/L respectively,there was significant difference in serum fibrosis markers among mild,moderate and severe fatty liver patients (F =675.719,398.771,303.960,840.570;P＜0.05),while the markers of patients with severe fatty liver were higher than normal.The ordinal logistic regression model showed that the serum fibrosis indexes of HA,LN,PC Ⅲ and C-Ⅳ had significant effects on the grading of fatty liver(P＜0.05),whose odds ratio were 1.322,1.229,1.899,3.935,that was the higher the HA,LN,PC Ⅲ,C-Ⅳ,the more severe fatty liver.Conclusion There were liver fibrosis trend in patients with severe fatty liver.Detection of serum markers of hepatic fibrosis can be used as an important basis for monitoring and diagnosis of fatty liver disease.
ABSTRACT
Heritable changes in gene expression are regarded as epigenetics,which do not involve coding sequence modifications.The study of ophthalmology epigenetics is a rapidly growing area in biomedical research.Epigenetic mechanisms principally include DNA methylation,histone modification,chromatin remodeling and noncoding RNA.Aberrant DNA methylation and histone modification are linked to a number of age-related disorders,such as cancer,autoimmune and others.In recent years,the modulations of epigenetic changes on the pathogenesis of eye disorders and their roles in therapeutic interventions are drawing more and more attention,and these studies deepen the understanding of relevant diseases.Since the epigenetic alterations are reversible,modifying epigenetic marks contributing to eye diseases provide a new approach to the development of disease prevention,diagnosis and therapies.Herein we discuss the roles of epigenetic changes in eye disease development,hoping that ophthalmologists and researchers pay attention to these researching cues in pathogenesis of eye disorders caused by genetic expression alterations in response to environmental changes,importantly,to the implication for relevant eye disease therapy and prevention.
ABSTRACT
RNA-seq can help us quickly obtain the whole transcriptome sequences of species under different conditions. Many Unigenes that are assembled by raw reads always do not contain complete open reading frame (ORF). In addition, it also has some redundancy in transcriptome library. Some Unigenes in the library, although belong to one transcript, cannot be assembled without overlapping. We found five incomplete Unigenes annotated ammonium transporter (AMT) from Salicornia europaea transcriptome, in which two Unigenes (Uni4 and Uni5) had identical expression patterns across four transcriptomes. The two Unigenes may come from one transcript. Analyzing the Unigene position of transcript by NCBI blastx, we found that Uni4 and Uni5 respectively located in 5' end and 3' end compared with the reference transcript, and an unknown gap of 120 bp may exist in a hypothetic transcript to which Uni4 and Uni5 both belong. To verify the hypothesis, single forward primer and single reverse primers were respectively designed on Uni4 and Uni5, and a fragment with about 800 bp was generated by PCR. Then it was sequenced and aligned with Uni4 and Uni5. Finally, we assembled a sequence with 1 667 bp, which contains a complete ORF (1 482 bp, coding 494 amino acids). It belongs to amt1 subfamily and was named Seamt1 via the phylogenetic analysis. It was pointed by bioinformatics tools that SeAMT1 protein conformed to the AMT characteristics of other species. This work clustered expression pattern to explore the Unigenes of one transcript, and the feasibility of this method was validated through the other two groups of Unigenes. The handy method will benefit extension and assembling of Unigene in transcriptome, it also helps achieve the complete ORF and gene function.
