2.The progression of laboratory diagnosis for urinary tract infection
Chinese Journal of Laboratory Medicine 2009;32(6):616-620
Urinary tract infection (UTI)is a commonly encountered disease during routine clinical care. In the mean time, it is also a commonly encountered hospital acquired infection. UTI possesses various clinical symptoms, and usually the symptoms are atypical. The detection of leukocyturia and bacteriuria is an essential index for screening and confirmatory diagnosis of UTI. This article summarized the pathogenesis of UTI, diagnostic criteria, clinical significance and application evaluation of detection of the WBC and bacteria in urine.
3.Study on the main disability reasons and their changes in the elderly with physical disabilities in China
Chinese Journal of Geriatrics 2009;28(2):164-167
Objective To understand the current status and the changes in main disability reasons in the elderly with physical disabilities during the past 20 years in China. Methods The data of the elderly with physical disabilities aged 60 years and over that were from the national sample survey on disability in 1987 and 2006 were analyzed and compared by epidemiology methods. Results In 2006.the main disability reasons in the elderly with physical disabilities aged 60 and over were disease factors,injury factors,other factors and congenital diseases and eccyliosis.The cause-specific disability prevalences were 5.262%,1.885%,1.000% and 0.200%respectively.Cerebrovaseular diseases showed the highest cause-specific disability prevalence of 2.552% in all the causes.Compared with the national sample survey in 1987,the cause-specific disability prevalences of disease factors and injury factors were obviously increased.The top five disability reasons in the elderly with physical disabilities aged 60 years and over in China were cerebrovascular diseases,arthropathy,miscellaneous traumas,other causes and unknown causes in the national sample survey in 2006;while vascular diseases,other traumas,other causes,unknown causes and pyogenic infection were the top five disability reasons in the national sample survey in 1987.The age-specific top five reasons were basically the same with the total top five disability reasons of the elderly with physical disabilities aged 60 years and over,and also the same relationship between sex-specific top five reasons and Iotal top five disability reasons in 1987 and 2006. Conclusions Disease factors are the main disability reasons of the elderly with physical disabilities aged 60 years and over,and cerebrovascular diseases have the highest cause specific disability prevalence.The prevention and cure of cerebrovascular diseases,arthropathy and other traumas become the key points to prevent physical disability in the elderly.
4.Whether preventive drainage is needed or not after abdominal surgery
Chinese Journal of Digestive Surgery 2008;7(5):325-326
Abdominal drainage is the most common technique applied in the abdominal surgery. According to the aim of drainage, it can be divided into curative drainage and preventive drainage, but there is no obvious difference between the 2 drainages. Abdominal drainage is not necessary after parenchymal viscera operation, but necessary after spleenectomy in preventing infection. For cavity viscera operation, abdominal drainage is applied according to the infectious condition, but scholars at home and abroad have different opinions on this point. Surgeons should pay attention to the placement of the drainage tube in patients who received preventive drainage.
7.Rupture risk and treatment strategies of small unruptured intracranial aneurysms
International Journal of Cerebrovascular Diseases 2015;23(12):945-950
In recent years, w ith the w idespread use of advanced neuroimaging techniques and the aging of the population, more and more asymptomatic smal unruptured intracranial aneurysms (sUIAs) are incidentaly detected in clinical practice. Studies have show n that the prevalence of unruptured intracranial aneurysm (UIA) is 2%-3% in adults, and more than 2/3 of them are smal aneurysms of < 7 mm in diameter. Usualy these sUIAs do not have any symptoms and the risk of rupture is low er. They are also know n as incidental or asymptomatic aneurysms, but they are not w ithout the risk of rupture. At present, there is no unified opinion about w hether to conduct conservative treatment or surgical clipping or endovascular interventional therapy. This article review s the latest research progress of sUIAs ( < 7 mm in diameter), hoping to provide more evidence for clinical assessment, decision -making, and individual treatment of this kind of aneurysms.
8.Study on the Interaction between Cefprozil and Bovine Serum Albumin by Spectrometry
China Pharmacy 2015;26(31):4360-4363
OBJECTIVE:To study the interaction of cefprozil (CE) with bovine serum albumine (BSA). METHODS:Under the temperatures of 289,299 and 309 K,the interaction of CE with BSA for 50 min had been studied by fluorescence quenching, UV spectrometry and synchronous fluorescence spectroscopy. Quenching constant(KSV)and speed constant(Kq)were calculated by Stern-Volmer equation. Static quenching constant(KLB)was obtained by Lineweaver-Burk equation,and UV spectrogram was used to determine the type of quenching. Double logarithmic equation was used to calculate the binding constants (Kb) and the number of binding site(n). Thermodynamic equation was used to obtain ΔH,ΔS,ΔG. Hill's coefficients(nH)was obtained by Hill equa-tion. RESULTS:At three different temperatures,with CE concentration increasing,fluorescence intensity of BSA decreased regular-ly. The value of KSV,Kq,KLB,Kb and n and nH decreased with the temperature increasing. ΔH,ΔS and ΔG were lower than 0. The numbers of binding sites were approximately equal to 1 and nH<1. CONCLUSIONS:CE statically quench the fluorescence of BSA,and the binding of them have been found to certain extent. The process of binding is spontaneous exothermic process. The main binding forces include Hydrogen bonds and Van der Waals forces,and primary binding site for CE is located at sub-domain ⅡA of BSA. There was some negative cooperative effect. CE would not affect the conformation of BSA. The binding site of CE and BSA is near by tyrosine residue.
9.Progress of application of continuous glucose monitoring system in newborns at risk of hypoglycemia
Chinese Journal of Applied Clinical Pediatrics 2016;31(19):1512-1514
Hypoglycemia is a common metabolic problem in newborn infants,which might lead to brain injury even brain death when it keeps extremely low for a long time.Therefore,it is of great importance to monitor blood glucose in neonates,especially in groups of infants who are at risk of hypoglycemia,in order to identify and treat this condition and prevent adverse neurological outcomes promptly.It is given that infant of a diabetic mother,preterm neonate,low birth weight and asphyxia are its risk factors.Relative to blood glucose monitoring methods in clinical,continuous glucose monitoring system is comprehensive,continuous and with low pain.Continuous glucose monitoring system has been applied in high-risk neonates of hypoglycemia in recent years.It is of great help to understand the complete picture and change trend of blood glucose,optimize blood glucose management,study newborn glucose metabolic characteristics and the relationship between hypoglycemia and brain damage,so as to define and manage neonatal hypoglycemia.
