1.Application of serum CK and BUN determination in monitoring pre-competition training of badminton athletes.
Journal of Huazhong University of Science and Technology (Medical Sciences) 2007;27(1):114-6
In order to investigate the feasibility of serum creatine kinase (CK) and blood urea nitrogen (BUN) in monitoring pre-competition training of badminton athletes, the pre-competition training load of 20 badminton athletes was studied, and serum CK and BUN were determined before, immediate and next morning after training. The results showed that after intensive training for one week, serum CK levels were significantly increased by 57.53 mmol/L (P<0.05). After regulation of the training intensity, average serum CK levels were increased by 21.79 mmol/L (P<0.05). BUN contents were increased by 0.83 mmol/L on average with the difference being not significant (P>0.05). After intermittent training, there was significant difference in the average increased levels of serum CK in athletes (P<0.05). There was significant difference before and after regulation of training (P<0.05). The increased levels of BUN were 0.78 mmol/L without significant difference (P>0.05). It was concluded that serum CK was one of the biochemical indicators monitoring the training load sensitivity of badminton athletes, but BUN was of little value in monitoring the training load. Both serum CK and BUN recovered slowly after one-week intensive training and intermittent training, suggesting the metabolic mechanism of human body in training needs further study.
2.Endometriosis and stem cell theory
Chinese Journal of Tissue Engineering Research 2016;20(28):4250-4256
BACKGROUND:Pathogenesis of endometriosis involves many factors that ultimately lead to the emergence of endometrial glands and stroma outside the uterine cavity. OBJECTIVE:To review the research progress in the theory of endometrial stem cel s, and to provide suggestions for the pathogenesis and treatment of endometriosis. METHODS:VIP database and PubMed database were retrieved for articles addressing endometriosis stem cel theory, including original research, experimental analysis, case analysis and review, published from January 2005 to October 2015. Keywords wereendometriosis, stem cel sin Chinese and English, respectively. After removal of repetitive articles, 48 articles were included for final analysis. RESULTS AND CONCLUSION:Endometrial stem/progenitor cel s may exist in the endometrium, and these cel s and bone marrow stem cel s are speculated to be involved in the occurrence of endometriosis. Therefore, treatment of endometriosis is targeted to endometrial stem/progenitor cel s and abnormal regulation on signal transduction pathway, which provides new insight into the mechanism of action and treatment of endometriosis.
3.Unexplained Elevated Maternal Serum Alpha-fetoprotein in Singleton Pregnancies as a Predictor of Fetal Risk.
Korean Journal of Obstetrics and Gynecology 1997;40(8):1608-1618
The aim of the study was to evaluate the significance of unexplained elevated mater- nal serum alpha-fetoprotein in singleton pregnancies as a prediction of fetal risk. The inclusion criteria for patents with unexplained MSAFP elevations were a MSAFP level 2.0 or greater multiples of the median ( MoM ), a single gestation, a confirmed gestatio- nal age and no fetal malformation or death on ultrasonography. In this study, 991 woman who attended the antenatal clinic at Taejeon Eul Ji Hospital from March, 1996 to March, 1997 were reviewed and data from 79 women with elevated maternal serum alpha-fetoprotein levels were analysed. The 67 of 79 patients with elevated maternal serum alpha-fetoprotein levels had on unexplained elevated MSAFP level. 13 women could not follow up. 54 pregnant women with unexplained elevated MSAFP levels were classified as the index group of singleton pregn- ancy and were matched against a control group. 108 patients with MSAFP levels 0.5 to 2.0 MoM served as control group. The incidence of antepartum hemorrhage ( placental previa ), preterm labor, intrauterine growth retardation ( IUGR ), low birth weight and pregnancy induced hypertension ( PIH ) in two groups was analyzed and the results was subjected to Fisher's Exact Test. None of the patients in the index group had chromosomal abnormalites or birth defect. IUGR occurred in 7 ( 12.96% ) of the index group babies but in only 3 ( 2.78% ) in the control group ( p < 0.02 ). preterm labor occurred in 5 ( 9.26% ) in the index group compared with 2 ( 1.85% ) in the control group ( p < 0.05 ). low birth weight occurred in 3 ( 5.5% ) of the index group babies and in 1 ( 0.9% ) in the control group ( p < 0.1 ). This study suggests that patients with unexplained midtrimester elevations of MSAFP are increased risk for IUGR, preterm labor. But no significance differences were observed in the incidence of low birth weight, antepartum hemorrhage ( placental previa ), PIH.

7.Apolipoprotein E gene polymorphism and ischemic stroke
International Journal of Cerebrovascular Diseases 2013;21(9):693-696
Apolipoprotein E (ApoE) has gene polymorphism (ε2,ε3,and ε4).It has been confirmed that ApoE structural and functional abnormlities are closely associated with the hyperlipidemia,formation of atherosclerosis,and its severity,while both hyperlipidemia and atherosclerosis are the risk factors for ischemic stroke.In recent years,although the relationship between the ApoE gene polymorphism and ischemic stroke has been extensively studied,the conclusions are not consistent.This article reviews the correlation studies between the ApoE gene polymorphism and ischernic stroke.
8.Effect of ephrin-A1/EphA2 on invasion of trophoblastic cells.
Journal of Huazhong University of Science and Technology (Medical Sciences) 2011;31(6):824-7
The effect of axon guidance factors ephrin-A1/EphA2 on the invasion of trophoblastic cells and the possible mechanism were investigated in this study. The expression of EphA2 in vascular endothelial cells was detected by immunohistochemistry. The proliferation and invasion of TEV-1 cells (an extravillous trophoblastic cell line) in first trimester were determined by cell counting kit-8 (CCK-8) and Transwell invasion assay. Real-time PCR was used to detect the expression of ephrin-A1 in TEV-1 cells treated with EphA2 at different concentrations (10, 50, 100, 500, 1000 and 5000 μg/L). The results showed: (1) EphA2 was expressed in the vascular endothelial cells; (2) EphA2 could promote the proliferation of TEV-1 cells. The proliferative capacity reached a peak in TEV-1 cells treated with 100 μg/L EphA2 (P<0.05); (3) EphA2 could increase the invasion of TEV-1 cells. The invasive ability was the greatest in TEV-1 cells treated with 500 μg/L EphA2 (P<0.05); (4) in the presence of EphA2 (0-500 μg/L), the expression of ephrin-A1 was increased concentration-dependently (P<0.05), but when the concentration of EphA2 was over 500 μg/L, the expression of ephrin-A1 ceased to increase (P>0.05). It was concluded that EphA2 can promote the invasion and proliferation of the human extravillous trophoblastic cells probably by regulating the ephrin-A1 ligand.
9.Implement bronchial provocative tests in children with asthma remission
International Journal of Pediatrics 2010;37(5):458-461
Bronchial asthma is one of the most common children health problems, with still increasing prevalence.Bronchial hyperresponsiveness is a characteristic feature of asthma,and its measurement may provide a useful adjunct in the diagnosis of asthma. Many children with asthma go into long-term clinical remission at adolescence, but bronchial hyperresponsiveness persists in approximately one half of these subjects, so implement the bronchial provocative tests in children with asthma remission may appears very important.
10.Clinical observation of combined lensectomy with vitrectomy, retaining the peripheral anterior lens capsule
International Eye Science 2014;(9):1689-1690
To investigate the curative effect of retaining the peripheral anterior lens capsule combined lensectomy with vitrectomy for ocular trauma.
●METHODS: Totally 33 patients ( 33 eyes ) with eye trauma underwent combined lensectomy with vitrectomy, retaining the peripheral anterior lens capsule and phase Ⅱposterior chamber lOL implantation. After follow - up of 6mo, visual acuity, intraocular pressure ( lOP ), lOL position, and intraoperative and postoperative complications were observed.
●RESULTS: Visions of all the patients were improved at varying degrees. After follow-up of 6mo, no obvious lens deflected and serious complications ( glaucoma, retinal detachment) appeared.
●CONCLUSlON: Combined lensectomy with vitrectomy, retaining the peripheral anterior lens capsule for ocular trauma has good curative effects of lessening complications during operation and postoperation and good visual acuity recovery.
