1.Mitogen activated protein kinase and chronic lung disease in preterm infants
International Journal of Pediatrics 2010;37(3):326-328
Chronic lung disease is a very common complication caused by inhaled hyperoxia, mechanical ventilation and pulmonary infection in preterm infants. It shows early inflammation and late alveoli fusion with mesenchymal fibroblast proliferation. Mitogen activated protein kinase is a very important signal transduction pathway in eukaryotic cells.It plays an important role in the cell inflammation, proliferation, differentiation, survival and apoptosis, which may contributes to the chronic lung disease.
2.Studying the infection and antibiotics resistant of chlamydia and mycoplasma in 2186 cases of female infertility
Journal of Chongqing Medical University 2007;0(10):-
Objectives:To investigate the prevalence situation and antibiotic resistance of chlamydia trachomatis (CT),ureaplasma urealyticum(UU) and mycoplasma hominis(MH) in infertile female patient,and to analyze the resistant of mycoplasma to common antibiotics. Methods:The cervical secretion samples from 2186 female infertility and 210 pregnancies women were collected. Then chlamydia trachomatis antigen was detected by immunoassay. Mycoplasma (UU and MH) were isolated and tested antimicrobial susceptibility for 12 kinds of antimicrobial drugs. Results:In the trial group 173 were CT-positive at a rate of 7.9%,and 1102 were positive for the mycoplasmae at a rate of 50.4%,of which 987 were UU infections and 115 were MH infections.The number of CT,UU and MH infections totaled 1275 cases,leading to an overall infection rate of 58.3%. The top three antibiotics for drug sensitivity in the UU,MH and UU+MH cultures were josamycin,minocycline and clarithromycin.The three antibiotics,to which the pathogens were most tolerant,included ofloxacin,norofloxacin and sparfloxacin. Conclusion:The infection rate of chlamydia and mycoplasma in infertility women is obviously higher than normal pregnanted,this shows the fact that chlamydia and mycoplasma infection of genitourinary tract may be one reason of infertility.The sensitivity of mycoplasma to common antibiotics especially to quinolones and macrolides has decreased.
5.Progress in effect of connective tissue growth factor in vascular smooth muscle cell's proliferation,migration and deposition of extracellular matrix
International Journal of Pediatrics 2010;37(2):152-154
Congenital heart disease often lost the opportunity of radical sureryfor secondary pulmonary hypertension.pulmonary hypertension is pathologicallycharacterizzed by pulmonary vascular remodeling,including the vascular smooth musclecell' s proliferation,migration and extracelluar matrix deposition,Recently,someresearchers have found that connective tissue growth factor can bind with somesurface receptors of vascular smooth muscle cells,causing some biological behaviorchanges such as proliferation,migration and extracellular matrix abnormaldeposition,and activating crresponding gene expression through this signaltransduction pathway.Pulmonary vascular remodeling may be one of the molecularpathogenesis in pulmonary hypertension.

This paper,introduced the manufacture process and quality control method of Xiao- erqingfei Suppository.The suppository tallied with requirements of China Pharmacopeia (the 85th edition).Its main active components were identified with TLC.Two represen- tative components were determined:ephedrine and glycyrrhizic acid.
8.Anti-snoring Pillow in the Treatment of Obstructive Sleep Apnea with Heart Failure: an Efficacy Study
Journal of Medical Research 2017;46(8):22-25
Objective To investigate the effect of anti-snoring pillow for the treatment of obstructive sleep apnea in patients with heart failure.Methods Forty seven HF patients with OSAHS and 12 HF patients with simple snoring were enrolled.All the patients were divided into 3 groups:control group (n =12),mild-moderate OSAHS group (n =26) and severe OSAHS group (n =21).All the patients received the treatment of anti-snoring pillow and their sleep apnea parameters were evaluated by PSG at the same time.Results The sleep apnea parameters including AHI,OAI,ODI,mean SpO2% and snore index were significantly improved in severe and mild moderate OSAHS group with anti-snoring pillow.Conclusion Anti-snoring pillow can reduce snoring index in all OSAHS patients and simple snorers.Sleep apnea and hypoxemia were greatly improved in mild-moderate OSAHS-HF patient while the anti-snoring pillow is not perfect in severe OSAHS patients with HF to replace PAP.
9.Advance on human umbilical cord mesenchymal stem cells for treatment of ALI in severe burns
Chinese Critical Care Medicine 2017;29(1):90-93
Severe burn is often accompanied by multiple organ damage. Acute lung injury (ALI) is one of the most common complications, and often occurs in the early stage of severe burns. If it is not treated in time, it will progress to acute respiratory distress syndrome (ARDS), which will be a serious threat to the lives of patients. At present, the treatment of ALI in patients with severe burn is still remained in some common ways, such as the liquid resuscitation, the primary wound treatment, ventilation support, and anti-infection. In recently, human umbilical cord mesenchymal stem cells (hUCMSCs) have been found having some good effects on ALI caused by various causes, but few reports on the efficacy of ALI caused by severe burns were reported. By reviewing the mechanism of stem cell therapy for ALI, therapeutic potential of hUCMSCs in the treatment of severe burns with ALI and a new approach for clinical treatment was provided.
10.The risk factors of nocturnal hypoglycemia in elderly patients with type 2 diabetes
Chinese Journal of General Practitioners 2009;8(10):736-738
This study was to evaluate the risk factors of nocturnal hypoglycemia in elderly patients with type 2 diabetes by continuous glucose monitoring system. Fifty-one type 2 diabetic patients aged 60 or above were enrolled and the episodes of nocturnal hypoglycemia were documented. The risk factors of nocturnal hypoglycemia were analyzed by logistic regression and the cut-off of glucose levels at bedtime for nocturnal hypoglycemia was evaluated. There were twenty-two patients with total 681 nocturnal hypoglycemic episodes. Logistic regression analysis showed that the lowest glucose level at bedtime was the risk factor of nocturnal hypoglycemia (OR=0.36, 95% CI:0.13-1.00, P<0.05), while the gender, age, diabetes duration, therapy regimen, the highest and average glucose levels at bedtime were not associated to nocturnal hypoglycemia. Receiver operating characteristic curve (ROC) showed that the bedtime glucose at≤6.2 mmol/L was the best cut-off point for predicting nocturnal hypoglycemia.
