ObjectiveTo investigate the relationship between the oxidative injury induced by low glucose and mitochondrial membrane potential in HUVEC-12 cells. Methods Human umbilicalvein endothelial cells HUVEC-12 were cultured in low concentration glucose for 4 h.Cell viability of HUVEC-12 cell was assessed with MTT assay.Dihydroethidium (DHE) was used as a reactive oxygen species (ROS)capture, which was detected the mean fluorescence intensity of samples and Rhodamine 123 as a fluorescence detector was to measure the level of mitochondrial membrane potential (MMP) in cells.Results Comparing to HUVEC-12 cells viability in 5.5 mmol/L glucose group (96.80 ±3.20)％, cells exposed to 2.8 mmol/L glucose group (66.40 ± 1.60) ％ and 0 mmol/L glucose group (58.93 ± 1.67) ％ were decreased by 32％ and 40％ respectively (P ＜ 0.01).ROS level of 5.5 mmoL/L glucose group, 2.8 mmol/L glucose group and 0 mmol/L glucose group were 0.59 ± 0.02, 0.74 ± 0.04 and 0.88 ± 0.05,respectivdy, increased by 25％ in cells exposed to 2.8 mmol/L glucose and by 48％ in cells without glucose exposure comparing to 5.5 mmol/L glucose group (P ＜0.01) ; MMP levels of 5.5 mmol/L glucose group,2.8 mmoL/L glucose group and 0 mmoL/L glucose group were 148.83 ± 3.51, 271.07 ± 19.54 and357.74 ±51.32 respectively, increased to 1.8 times in cells exposed to 2.8 mmol/L glucose and to 2.4times in cells without glucose exposure comparing to 5.5 mmoL/L glucose group (P ＜ 0.01).Conclusion Low glucose leads to injury in HUVEC-12 cells, which is probably induced by the oxidative stress via the increasing MMP.

Objective To investigate the changes and significance of concentration of soluble intercellular adhesion molecule-1(sICAM-1) in cerebrospinal fluid (CSF) of bacterial meningitis(BM) in rabbits. Methods A total of 36 rabbits were randomly divided into m eningitis group, meningitis cefotaxime-treated group and control group. BM indu ced by escherichia coli(Ec) via cerebellomedullary cistern inoculated. Normal sa line was injected in control group. CSF was sampled in different time. The conce ntration of CSF sICAM-1 was detected by ELISA.Results 1.There was a low concentration of sICAM-1 in CSF in 85 percent of normal rabbi ts.2.In meningitis group, there was a sharp rise in the concentration of CSF sIC AM-1 at 6 hours after Ec was inoculated, reached a peak level at 12 hours, and t here was higher concentration of CSF sICAM-1 between 6 and 24 hour than that at 0 hour.3.In meningitis cefotaxime-treated group, the concentration of CSF sICAM -1 at 6 hour and 12 hours was similar to meningitis group, the time that get pe ak level was at 24 hours that at 12 hours after making use of antimicrobial agen t.The peak level was higher than meningitis group. The concentration of CSF sICA M-1 decreased markedly at 48 hours that made use of antimicrobial agent 36 hour s later,but the concentration was still higher than the peak level of meningitis group.Afterwards, with the time of making use of antimicrobial agent lengthened ,the concentration of CSF sICAM-1 decreased gradually.4.Experimental results in dicated by correlating analysis to these data that there was positive correlatio n in the concentration of CSF sICAM-1 with the brain water content.Conclusions sICAM-1 participates in the pathological process of BM, and contributes to the damage of blood brain barrier and the formation of brain edema.There is importan t significance that drugs which can resist the discharge of sICAM-1 will be impl ied.

Objective To observe the effect of core stability training on motor function, balance and activities for children with cerebral palsy. Methods 100 children with cerebral palsy were divided into control group (n=50) and treatment group (n=50). The control group accepted routine physical therapy, occupational therapy, acupuncture, sensory integration training and conductive education; while the treatment group accepted core stability training in addition, 3 hours a day for 12 weeks. They were assessed with Gross Motor Function Measure (GMFM-88), Berg Balance Scale (BBS) and Comprehensive Functional Assessment for Disabled Children (CFA-DC) before and after treatment. Results The scores of GMFM-88, BBS and CFA-DC improved more in the treatment group than in the control group (P<0.05). Conclusion Core stability training can further promote the recovery of motor, balance and activities in children with cerebral palsy.

To ensure the quality and safety of Panax notoginseng, a method for the simultaneous determination of 10 mycotoxins in Panax notoginseng was developed using ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). The sample was extracted with acetonitrile and purified by HLB multifunction cleanup column. The separation was performed on a Phenomenex Kinetex XB-C18 column by gradient elution using methanol and 5 mmol·L(-1) ammonium acetate as mobile phase. The targeted compounds were detected in MRM mode by mass spectrometry with electrospray ionization (ESI) source operated in both positive and negative ionization modes. The linear relationships of the 10 mycotoxins were good in their respective linear ranges. The correlation coefficients (r) ranged from 0.9981 to 1.0000. The LOQs of the 10 mycotoxins were between 0.15 and 8.6 μg·kg(-1). The average recoveries ranged from 73.8% to 107.0% with relative standard deviations (RSDs) of 0.10%-10.9%. The results demonstrated that the proposed method was sensitive and accurate, and suitable for the mycotoxins quantification in Panax notoginseng.

Objective To describe the treatment experience of post-operative complications after total arch replacement for acute type A aortic dissection in 34 cases.Methods The subjects were 34 consecutive patients (Twenty-eight males and 6 females,age 34.0 -60.0 yrs) who received total arch replacement for acute Stanford type A aortic dissection from Jan.2005 to Oct.2010 in our hospital.The duration from the onset of the symptoms to the hospitalization ranged from 4 - 18 hrs.Pre-operative 2-D Echo revealed aortic valve regurgitation in 8 patients and mitral valve regurgitation in 1 patient.Results Three patients died after operation ( mortality 8.8％ ).Severe complications included acute kidney injury in 13 cases,respiratory dysfunction in 12 cases,paraplegia in 1 case,mental disorder in 10 cases and excessive post-operative bleeding in 2 cases.Conclusion The incidence of the complications after total arch replacement is still high and severe.Intensive care should be stressed peri-operatively and early diagnosis and treatment for post-operative complications are important procedures.

Objective To evaluate the clinical significance of the change of serum matrix metalloproteinases (MMP)-1,-2,-3 and -9 in acute and chronic aortic diseases and acute myocardial ischemia.Methods The blood serum levels of MMP-1,-2,-3 and -9 were detected in 30 patients with acute aortic dissection,19 patients with chronic aortic dissection,19 patients with aortic aneurysm and in 12 patients with acute myocardial ischemia,as well as in 16 healthy individuals who served as the control group.Serum MMP levels were measured by using an ELISA technique.Results There were significantly higher levels of MMP-3 in patients with acute myocardial ischemia as compared to acute aortic dissection ( [19.10 ± 3.11 ] μg/L vs [11.89 ± 1.31 ] μg/L,P =0.02).Significantly lower levels of MMP-1 were found in healthy controls compared to the groups of patients ( [1.30 ± 0.56 ] μg/L vs [2.99 ± 0.78 ] μg/L in acute aortic dissection,P =0.03,[3.12 ±0.78] μg/L in chronic dissection,P =0.02,[3.01 ± 1.01 ] μg/L in thoracic aortic aneurysm,P =0.03 and [5.01 ± 0.98 ] μg/L in acute myocardial ischemia,P =0.01 ).Higher levels of M MP-1 and MMP-3 were detected on males.There was a positive correlation between MMP-1 and increasing age ( r =0.38,P ＜ 0.05 ).In patients operated for acute type A aortic dissection,the levels of MMP-1,MMP-3 and MMP-9 increased immediately after surgery,while the levels of MMP-2 decreased.Twenty-four hours after surgery levels of MMP-1,-2 and -9 were almost equal to the preoperative ones( P ＞ 0.05 ).Conclusion Measurement of serum MMP levels in thoracic aortic disease and acute myocardial ischemia is a simple and relatively rapid laboratory test that could be used as a biochemical indicator of aortic disease or acute myocardial ischemia,when evaluated in combination with imaging techniques.
