1.Issues needed to be resolved in the accurate quantification in detection of urine albumin
Chinese Journal of Laboratory Medicine 2009;32(10):1088-1090
The quantification of albumin in urine, especially the use of "microalbumin" in recent years is very important routine test and played important role for the early diagnosis and monitoring of kindney injures. But that routine test which seems common still has many problems to be solved. Here we introduce some differences in this test guidelines issued by authorities of some countries, some problems and the improvement advice given by international organizations, and put up suggestions to improve the quantitation accuracy, including replace ment of the term of "urine microalbumin" by " urine albumin".
2.New clinical application of gamma-glutamyltransferase
Chinese Journal of Laboratory Medicine 2003;0(09):-
The routine biochemistry test-serum ?-glutamyltransferase(GGT,?-GT)has long been used for the diagnosis and differential diagnosis of liver and bile duct diseases.Recent studies showed that high level serum GGT associated with occurrence of chronic kidney disease or insulin-resistance and type 2 diabetes afterward.Also,it can predict the occurrence of acute myocardial infarction or stroke.So,high level serum GGT associated with all-cause mortality in population.Serum GGT might be an indicator of oxidative stress showing the injures of cells by oxygen radicals and a predictive index of many diseases.More attention should be paid and emphasized on its predictive value.

4.Gegen Qin Lian Tang combined with human amniotic mesenchymal stem cell transplantation for early diabetic retinopathy
Chinese Journal of Tissue Engineering Research 2016;20(19):2824-2830
BACKGROUND:Human amniotic mesenchymal stem cel s have the potential to differentiate into insulin-secreting cel s and have immunomodulatory effects. Additional y, it has been clinical y proved that Gegen Qin Lian Tang can lower blood sugar. OBJECTIVE:To investigate the effects of Gegen Qin Lian Tang combined with human amniotic mesenchymal stem cel transplantation on rat early diabetic retinopathy, by detecting pathological changes, levels of blood indicators and expressions of vascular endothelial growth factor in retinal tissues. METHODS:By intraperitoneal injection of streptozotocin, 42 Wistar rat models with diabetes mel itus were prepared and then randomly divided into model group, human amniotic mesenchymal stem cel transplantation group (cel transplantation group) and combination of human amniotic mesenchymal stem cel s and Gegen Qin Lian Tang group (combination group). At 4 weeks after transplantation, levels of blood sugar and serum insulin in diabetic rats were detected;pathological changes of the retina in diabetic rats were observed by hematoxylin-eosin staining. Besides, expressions of CD45 and vascular endothelial growth factor mRNA were detected using immunohistochemistry staining and RT-PCR technology, respectively. RESULTS AND CONCLUSION:Compared with the model group, the levels of blood glucose and serum insulin in both cel transplantation and combination groups were significantly decreased and increased, respectively, and these changes were even more significant in the combination group (P<0.05). In the model group, the retinal edema could be found, accompanied by structural disorder and irregular cel arrangement, while these retinal lesions were relatively milder in the cel transplantation group and significantly improved in the combination group. In addition, the CD45 expression and in the retina was highest in the model group subsequently fol owed by the cel transplantation group (P<0.05) and lowest in the combination group (P<0.05). Furthermore, compared with the model group, the expression of vascular endothelial growth factor mRNA was also significantly lower in the other two groups, especial y in the combination group (P<0.05). These data show that Gegen Qin Lian Tang combined with human amniotic mesenchymal stem cel transplantation improves the severity of diabetic retinopathy by inhibiting expressions of CD45 and vascular endothelial growth factor in the retinal tissues.
5.Application of Neurobehavioral Evaluation in Environmental Epidemiology Researches
Journal of Environment and Health 1989;0(06):-
In recent years, neurobehavioral end point was often used in environmental epidemiological researches to assess and characterize the adverse effects of environmental pollutants. The applications of neurobehavioral evaluation not only improve the ability to identify the early, sub clinic adverse effects of environmental pollutants exposure, but also help to screen out the victims for further protection. At present, there are many neurobehavioral evaluation methods have been applied in the environmental epidemiological researches at home and abroad, some methods that are considered applicable in China were reviewed in this article.
6.Blood Lead Levels of Children in China
Journal of Environment and Health 1989;0(06):-
Objective To describe blood lead levels (BLLs) and the distribution character of children in China as a whole. Methods The research papers on children's BLLs published in 1994-Mar,2004 were collected through Chinese Biomedical Disc(CBMDisc) or other ways, and 32 papers were selected into the present analysis according to the four main criteria: (1) BLLs were measured by graphite atomic absorption spectroscopy (GFAAS) or inductively coupled plasma-mass spectrometry(ICP-MS); (2) high quality guarantee and quality control were reported, standard substance using was necessary; (3)there were no local lead pollution resources in the areas where the involved children lived in; (4)the samples were more than 100. Results The mean BLL of Chinese children was 92.9 ?g/L(37.2-254.2 ?g/L)and 33.8%(9.6%-80.5%)of children, as for individual BLL, were higher than 100 ?g/L. It indicated that BLLs in boys were significantly higher than that in girls(P

Objective: To study the dosage application of herbs in class formulas of KaixinSan recorded in Prescriptions of the Bureau of Taiping People's Welfare Pharmacy (Taiping Huimin Hejiju Fang), Essential Recipes for Emergent Use Worth A Thousand Gold (Beiji Qianjin Yao Fang) and Records of Approved Cases of Ancient and Recent Times (Gujin Luyan) and their actions on depression. Method: According to the dosage proportion of different herbs in the three formulas in the three books, two methods were adopted in terms of decocting different herbs separately and mixing them thereafter(group of decocting separately) as well as extracting after decocted all the herbs together (group of decocting together). Classical anti-depression mice models--forced swimming and tail suspending experiments were observed. The data of immovability time of mice were analyzed by statistics. Result: All the class formulas of KaixinSan which have the same medication but different proportion in the three medical books can reduce the immovability time of mice in forced swimming and tail suspending experiments. But the action of KaixinSan recorded in Prescriptions of the Bureau of Taiping People's Welfare Pharmacy was prominent, and the action of the group of decocting together was superior to that of separated decocting. There was significant difference between the group of decocting together in low dosage and the controlled one (P
