Chinese Journal of Endocrinology and Metabolism 2015;31(10):837-838
The prevalence of obesity,type 2 diabetes,and other chronic non-communicable diseases is increasing rapidly world-wide.Most recent epidemiological data showed that China is now in an era of obesity,and under a huge burden of the complications related with obesity,diabetes,as well as cerebral-and cardiovascular disorders.Strenuous efforts,comprehensive strategies,effective measures,and practical solutions must all be taken to combat against these chronic diseases.
3.Capillary Electrophoresis of Neurotransmitters Under the Control of Radial Electric Field
Chinese Journal of Analytical Chemistry 2001;29(6):661-663
Separations of neurotransmitters such as dopamine (DA), ser otonin (5-HA), norepinephrine (NE) and epinephrine (E) were performed successf ully using a homemade electric field modulated capillary electrophoretic system, which could offer both radial and axial electric fields with only one high volt age power supply. DA and 5-HT were eluted simulaneously and could not be resolv ed in 0.01 mol/L phosphate buffer at pH 2.5. Alcohol additives, such as methanol , ethanol or 1-propanol were added to the buffer to change the solvation shell of the solutes, which changed their effective sizes and electrophoretic mobiliti es of the solutes accordingly. The optimum composition was a buffer of 20% (V /V) 1-propanol, with resulted resolutions 0.74 (DA/5-HT), 0.56(5-HT/NE) and 0.77 (NE/E). If a positive radial voltage of 6.6 kV was applied, the resolut ions were improved to 1.48, 0.71 and 1.32, respectively.

Chinese Journal of Health Management 2008;2(1):27-29
Objective To study the relationship between the aged retirees' group's body mass index(BMI)distribution characteristics and relative cardiovascular diseases risk tactors.Methods One thousand three hundred and forty-three retirees in health medical examination were tested for systolic pressure, diastolic pressure,serum triglyceride,total cholesterol and fasting blood glucose.Groups with different BMI and different genders were tested for their mortality.Results The detective rates of BMI insufficiency,normal,overweight and obesity were 6.18%,51.67%,35.52%and 6.63%respectively.There was no statistic significance between different genders.The prevalence rates of hypertension,hyperlipidemia and diabetes mellitus(DM)were 46.09%,46.91%and 7.45%respectively.It showed that the prevalence rates of male hypertension and hyperlipidemia were significantly above those of the female's(P<0.05).As the BMI increased,hypertention,hyperlipidemia and DM rates increased too,and obviously increased in overweight group compared to normal BMI group(P<0.05).The detective rate of cardiovascular disease increased correspondingly with the increase of BMI.Conclusion BMI increasing is the important vascular relative risk factor for the aged retriee.
5.Improved methods of establishing rabbit VX2 hepatocarcinoma models
Chinese Journal of Tissue Engineering Research 2015;(27):4361-4364
BACKGROUND:Rabbit VX2 hepatocarcinoma models are characterized by expanded and infiltrative growth, abundant blood supply, similar pathological and imaging features to human hepatocelular carcinoma, so this model is ideal for imaging experiments. OBJECTIVE: To establish rabbit VX2 hepatocarcinoma models and compare two different laparotomy methods in establishing rabbit VX2 hepatocarcinoma models. METHODS:Thirty New Zealand rabbits were randomly divided into two groups: traditional laparotomy (tumor particles were directly embedded into the liver with tweezers) and improved laparotomy (tumor particles were injected into the liver through a 15G syringe needle). The growth features of the tumor established in two different ways were compared by ultrasound. RESULTS AND CONCLUSION:The tumor formation rate was 100% in the two groups; the single rate was respectively 50% and 90%; the ectopic implantation rate was 50% and 10%, there were significant differences between two groups (P < 0.05). The mortality rate within 2 weeks was 33% and 0 in the two groups, with significant differences (P < 0.05). The improved laparotomy method is feasible for modeling rabbit VX2 hepatocarcinoma, due to minimal injury, short operation time, high success rate and stable features.
6.Application of covered stents in the treatment of intracranial aneurysms
International Journal of Cerebrovascular Diseases 2014;22(3):231-236
Since the 1960s,endovascular coil embolization has gradually become another treatment for intracranial aneurysms in addition to craniotomy clipping surgery,and in recent years,it has become the preferred method for many neurologists.However,the complexity of intracranial vascular anatomy and the diversity of intracranial aneurysm make the coil embolization alone unable to meet the needs of all intracranial aneurysms.And then some novel materials and techniques emerged,such as coated coils,balloon-assisted embolization,stent-assisted embolization,and covered stents.The principle of covered stents for the treatment of intracranial aneurysms is to place a kind of stents with bio-physical barriers into the parent arteries,while maintaining the patency of the parent artery,thus isolating aneurysms,leading to thrombogenesis inside and finally curing the lesions while maintaining the patency of parent arteries.It has huge advantage in the treatment of wide-necked,huge,dissecting and pseudo aneurysms without important adjacent branch vessels.This article reviews the application situation and the prospects of development of covered stents in the treatment of intracranial aneurysms.

Acta Medicinae Universitatis Scientiae et Technologiae Huazhong 2000;29(5):469-470,479
To investigate the antibiotic resistance of bacteria isolated from bile, the bile from the surgical in-patients with bile duct infection from June 1995 to December 1998 was cultured and the distribution and antibiotic resistance of the isolates (not including anaeobes) were analyzed. The results showed that the cultured positive rate in the specimens was 69. 76 % (143/205). Among the isolates, most of them were E. coli and P. aeruginosa (31. 74 % and 18. 56 %, respectively), while Enterobacter, K. pneumonia and Enterococci were also commonly seen. All the isolates were resistant more or less to the commonly used antibiotics.
