Objective To explore the effects of thiamine and riboflavin on H2O2-induced DNA oxidative damage in human umbilical vein endothelial cell line ECV304.Methods ECV304 cells were incubated with 10,100,500,1000 mg/L of thiamine or 20,100,300,500 nmol/L of riboflavin for 24 h,and then oxidative damage of cells were induced by 25 mol/L H2O2 for 30 min.DNA damage was detected with single cell gel electrophoresis(SCGE)assay.ECV304 cells incubated without H2O2,thiamine and riboflavin were served as negative controls,and those incubated with H2O2 and without thiamine and riboflavin were served as positive controls.Results H2O2 induced DNA damage,and the indices of percent of DNA damage cells,percent of tail DNA,tail length and Olive tail moment were increased.The indices of cells pretreated with 10,100,500 mg/L of thiamine or 20,100,300 nmol/L riboflavin were significantly decreased(P0.05).Conclusion Proper supplementation of thiamine and riboflavin may decrease H2O2-induced DNA oxidative damage,while excess thiamine and riboflavin supplementation may be harmful to DNA and enhance the susceptibility to H2O2 potentially.

ObjectiveTo compare the levels of sFas in the sera among Kawasaki disease (KD),incomplete Kawasaki disease (IKD),and normal control groups,and to analyze the relationship of sFas with IKD children.MethodsA total of 32 cases of acute KD and acute IKD children,and 20 cases of the control children were selected,respectively.The levels of serum sFas among three groups were measured using ELISA kits.Each child among the three groups was examined by echocardiography.Results(1)The levels of serum sFas among the three groups were[ (0.54±0.20)ng/L in KD,(0.55±0.16)ng/L in IKD,and (0.24 ± 0.04) ng/L] in control group,respectively.The overall means of sFas in the KD and IKD groups were higher than the control group,and the differences were statistically significant( F=29.276,P＜0.05 ).(2)The levels of serum sFas among echocardiography abnormal and normal groups were[ (0.65±0.19) ng/L and (0.49±0.10)ng/L],respectively; and the difference between two groups were statistically significant ( t=3.139,P ＜ 0.05 ).ConclusionsThe expression levels of sFas in the peripheral serum of IKD children were increased,and there was a close association of overexpression of sFas with the cardiovascular damage in IKD children.

Objective To investigate the clinical features and treatments of pituitary abscess.Method The clinical data of 6 patients with pituitary abscess were examed along with a review of the literature.Results Of 6 patients,headache was presented in 5 patients,hypopituitarism in 4 patients,visual disturbance and/or bitemporal hemianopsia in 4 patients and fever in 1 patient.MRI and CT images showed a cystic sellar lesion with ring enhancement in 5 patients.Preoperative diagnosis of pituitary abscess was made in 2 patients,pituitary adenomas in 3 patients and craniopharyngiomas in 1 patient.All cases were treated surgically by transsphenoidal approach in 5 patients and transscranial in 1 patient.Followed with postoperative antibiotics therapy for 3 weeks,the symptoms were improved postoperatively in all cases.Followed up 8 months to 10 years,1 patient who underwent craniotomy recurred and wag cured by via transsphenoidal surgery.Conclusions The pituitary abscess is easily misdiagnosed.The cystic pituitary lesion should be considered the possibility of pituitary abscess.Transsphenoidal surgery and proper perioperative antibiotics therapy are the keys to the treatment of pituitary abscess.

A bacterial strain which could grow well on the substrate of PAEs as the sole source of carbon and energy was isolated from contaminated sludge in the river of WeiFang in ShangDong province and it was designated as JDC-3. Based on the morphology,biophysical and biochemical properties as well as molecular characteristics,this isolate was preliminarily identified as Delftia sp.. A fragment of phthalate dioxygenase gene was successfully amplified from the genus of Delftia for the first time using a set of degenerate primers. Meanwhile,the degradation capability of JDC-3 was determined by HPLC using DMP as test substrate. The results showed that the optimal pH and temperature were at 7.0～8.0 and 30?C～35?C respectively. The degradation kinetics of JDC-3 was studied in different initial DMP concentration under optimal conditions. The results indicated that the degradation dynamic equation was ln C =-0.06837 t + A when DMP concentration was lower than 300 mg/L,with half life of 12.48 h. The degradation rate decreased and half life of JDC-3 prolonged as the initial concentration kept on increasing.

Objective To investigate the causes,clinical manifestations and treatments of cerebrospinal fluid(CSF)leakage following the treatment of prolactinomas with bromocriptine.Methods The data of 2 patients with prolactinomas and CSF leakage following bromocriptine treatment,were retrospectively analyzed and the associated literatures were reviewed.Results Two patients with massive invasive prolactinomas eroding the skull base developed CSF leakage within 1 month after commencing bromocriptine treatment.Bromocriptine treatment was stopped and external ventficular drainage was performed in 1.Bromocriptine treatment was stopped and transsphenoidal surgery in debulking the tumor and sealing the leakage with fibrin glue was performed in the other patient.The bromocriptine treatment was resumed with a lower dose in both patients and the CSF leakage never recurred in the follow-up of 9-36 months;the serum prolactin decreased and the tumor shrank gradually.Conclusions CSF leakage may develop in bromocriptine-treated patients with invasive prolactinoma eroding skull base.Surgical repair of the fistula,withdrawal of bromoeriptine and additional external CSF drainage are the effective ways in treating CSF leakage.Resuming bromocriptine treatment with a lower dose can induce gradual decrease of the serum prolactin and shrink of the tumor.

OBJECTIVETo study the primary effects of Niuhuang Qingwei wan on the gastrointestinal function in aninmal for justifying its efficacies in clinic.

METHODMice were twice administered with Niuhuang Qingwei wan (0.83, 1.67, 3.33 g x kg(-1), ig) and rats were twice administered with Niuhuang Qingwei wan (0.59, 1.18, 2.36 g x kg(-1), ig). The effects on the stomach function were evaluated by the gastric emptying test in mice and the gastric analysis in rats. The effect on the intestinal function were evaluated by the propulsive motility of the total gastrointestinal tract test in mice by recording the time and frequency of excreting carbo medicinalis. Its analgesia was explored by using the abdominal constriction test induced by acetic acid.

RESULTNiuhuang Qingwei wan decreased the activity and secretion of pepsin in a dose-dependent manner (P < 0.01, P < 0.05), the gastric juice volume at middle and high doses (P <0.01, P <0.05), and the gastric acid volume at high dose (P <0.05); However, it had no significant effects on the gastric emptying in normal mice and the acidity in gastric juice. It shortened the excreting time of feces and increased the frequency of defecation (P < 0.01, P < 0.05). It also inhibited abdominal constriction responses at high dose, and the inhibition rate was 40.0% (P <0.01).

CONCLUSIONNiuhuang Qingwei wan can promote gastrointestinal motility, decrease gastric acid volume and activity of pepsin and show certain analgesia effect. Those findings are consistent with its treating stomach heat in clinic.

In large prospective studies, plasma fibrinogen levels have been shown to be an independent risk factor of vascular disease, including ischemic stroke. Elevated plasma fibrinogen in an individual could be due to the presence of predisposing genetic and/or environmental factors, such as smoking. Of the polymorphisms studies to date, the beta-fibrinogen-455 (beta-Fg-455) G-->A substitution in the 5' flanking region is associated with the most consistent difference in plasma fibrinogen levels in both case-control studies and in selected groups of healthy individuals. In order to further elucidate the role of the beta-Fg-455 G-->A substitution in determining fibrinogen levels and susceptibility to ischemic stroke in case-control population, including 104 individuals with verified ischemic stroke and 156 healthy individuals. Turbidimetriy assays were used to measure plasma fibrinogen levels of all samples. The beta-Fg-455 G-->A mutation was identified by the polymerase chain reaction followed by restriction enzyme digestion of the amplified DNA with HaeIII. The plasma fibrinogen level in patients with ischemic stroke [(3.51 +/- 1.09) g/L] was significantly higher than that in the control [(3.08 +/- 0.71) g/L] (P < 0.01). The A-allele is associated with elevated fibrinogen levels in both patients and controls. The plasma fibrinogen levels in controls with A-allele in elder people were higher than in younger people (P < 0.05). Those with A allele in males of ischemic stroke had significantly higher plasma fibrinogen levels in smokers than in non-smokers and ex-smokers (P < 0.05), but it was not significantly difference in subjects of GG genotype (P > 0.05). Our data demonstrates an association of the beta-Fg promoter A-455 allele with higher fibrinogen levels in the general population, and suggests that the A-allele may be a susceptible predictor of ischemic stroke, particularly in aging and smoking.
