Objective To investigate serum cardiac troponin T(cTnT) and C-reactive protein (CRP) levels and assess the prognostic values of cTnT and CRP of mortality and cardiovascular events in maintenance hemodialysis (MHD) patients. Methods One hundred and six MHD patients were enrolled in this study. Serum cTnT, CRP, creatinine, albumin were measured in pre-hemodialysis at the beginning of the study. The mortality and cardiovascular events were recorded during the period of follow up. Results At the initiation of the study,28 patients (26.42%) were recorded with positive cTnT level, 32(30.19%) with positive CRP and 16 (15.09%) with positive cTnT and CRP. Logistic regression analysis showed a significant correlation between serum cTnT and serum CRP and Scr. Patients with positive cTnT and CRP levels had higher mortality and more cardiovascular events than those with negative levels. Kaplan-Meier survival analysis showed a significant difference between patients with normal and abnormal cTnT and CRP levels. Conclusions Some MHD patients have elevated serum cTnT level. Serum cTnT level is correlated with serum CRP and creatinine level. Patients with positive cTnT and CRP levels have higher mortality and more cardiovascular events than those with negative levels.

Objective To investigate the effect of excessive fluoride,aluminum on Zn,Fe,Ca,Mg,Cuin rat blood.Methods Forty eight SD rats were randomly divided into 4 groups matched with their weights:control group,high aluminum group,high fluorine group and high fluorine-aluminum group.Aluminum content in their drinking water was 0,90,0,90 mg/L respectively.Fluorine content of their feed was 5.2,5.2,106.0,106.0 mg/kg and aluminum Was 6.8,6.8,19.7,19.7 mg/kg respectively.90 days later,the level of blood Zn,Fe,Ca,Mg, Cu Was detected by the atomic absorption spectrometry.Results Compared among these groups,Zn,Fe,Mg and Cu content of the whole blood had significant difierences(F=46.25,14.74,6.10,2.93,P<0.05),while Ca content of the whole blood did not significantly change(F=2.81.P>0.05).Factorial analysis showed that excessive intake of aluminum could significantly decreased Zn,Fe,Mg content of the blood(F=42.66,5.41,7.04,P<0.05)and excessive intake of fluorine could significantly decreased Zn,Fe,Mg,Cu content of the blood(F=64.50,37.90,9.75,6.74, P<0.05).The coexistence offluorine and Muminum had interaction to the level of Zn(F=31.59,P<0.05)and did not obviously interact with other elements(F=0.91,1.63,1.51.0.00,P>0.05).Compared with the control group [(131.30 ±13.86)μmol/L,(10.24 ±1.02),(1.71 ±0.19)mmol/L,(20.43 ±4.42)μmol/L],Zn content in the high aluminum group[(90.84±9.98)μmol/L]decreased significantly(P<0.05),so did Zn,Fe,Mg content in tlle high fluorine group[(85.85 ±10.92)μmol/L,(8.49 ±0.68),(1.52 ±0.13)mmol/L],the difference being statistically significant(P<0.05)0Zn,Fe,Mg,Cu content in the high fluorine-aluminum group,being(82.82 ±11.00)μmol/L, (8.16±0.45),(1.46±0.09)mmoL/L,(15.69±2.38)μmol/L,respectively,all decreased signitlcarIdy(P<0.05). Compared with the high aluminum group[(9.43±1.09)mmol/L],Fe content of the high fluorine aluminum group[(8.16±0.45)mmol/L]decreased significantly(P<0.05).Conclusions Excessive fluoride can cause blood zn, Fe,Mg,Cu decline,so can excessive aluminum.Combination of excessive fluofine and aiuminum has 8ignificant synergic effect on the level of Zn but have rio influence on Ca.

Aim To study relative bioavailablity of cefaclor effervescent tablets in healthy volunteers. Methods According to the crossover design, A volunteers were each orally given a single does of the 0.75 g cefaclor effervescent tablets and cefaclor capsules with an interval of 5 days between the two formulations.The plasma concentrations of the drug were determined by RP-HPLC.Pharmacokinetic parameters were obtained by ATPK programe,and calculated on the basis of open single compartment model.Results After a single oral dose, the peak levels in plasma averaged Cmax(31.27?5.81)?g?ml-1 and(30.56?5.25) ?g?ml-1 at (0.58?0.12)h and(0.73?0.17)h and AUC0～4(35.48?4.65) ?g?h?ml-1 and (35.89?2.90) ?g?h?ml-1 for tablet and capsule,respectively. Conclusion The result shows that two formulations are bioequivalence.

This study was aimed to explore the role of human fetal bone marrow stromal cells (FBMSC) in combination with exogenous cytokines in supporting the in vitro expansion of cord blood mononuclear cells and the expression of CXCR4(+) and CD49d(+) in CD34(+) cells. Mononuclear cells (MNC) separated from cord blood (CB) were cultured in a serum-free support culture system with FBMSC or exogenous cytokines or both of them. On day 0, 6, 10 and 14, total cells were counted, CD34(+), CD34(+)CXCR4(+) and CD34(+)CD49d(+) cells were quantitated by FACS, and hematopoietic progenitor cells were assessed by semisolid culture assay. The results showed that after culturing for 14 days, CD34(+) cells, CD34(+)CXCR4(+) cells, CD34(+) CD49d(+) cells and colony forming unit (CFU) were significantly increased (P < 0.05). Compared with other groups, expansion multiple of CD34(+), CD34(+)CXCR4(+), CD34(+)CD49d(+) cells and CFU were higher than that in FBMSC and cytokine group (P < 0.05). It is concluded that the culture system used in this study can not only support the expansion of CB MNCs but also increase the number of hematopoietic stem and progenitor cells which has chemokine and adhesion capacity. This culture system may be a feasible way for in vitro culture of cord blood cells.

BACKGROUND: The effect of pituitary adenylate cyclase activating polypeptide (PACAP) during traumatic brain injury (TBI) and whether it can modulate secondary injury has not been reported previously. The present study evaluated the potential protective effects of ventricular infusion of PACAP in a rat model of TBI. METHODS: Male Sprague Dawley rats were randomly divided into 3 treatment groups (n=6, each): sham-operated, vehicle (normal saline)+TBI, and PACAP+TBI. Normal saline or PACAP (1g/5L) was administered intracerebroventricularly 20 minutes before TBI. Right parietal cortical contusion was produced via a weight-dropping method. Brains were extracted 24 hours after trauma. Histological changes in brains were examined by HE staining. The numbers of CD4+ and CD8+ T cells in blood and the spleen were detected via flow cytometry. RESULTS: In injured brain regions, edema, hemorrhage, inflammatory cell infiltration, and swollen and degenerated neurons were observed under a light microscope, and the neurons were disorderly arrayed in the hippocampi. Compared to the sham group, average CD4+ CD8– lymphocyte counts in blood and the spleen were significantly decreased in rats that received TBI+vehicle, and CD4– CD8+ were increased. In rats administered PACAP prior to TBI, damage was attenuated as evidenced by significantly increased CD4+, and decreased CD8+, T lymphocytes in blood and the spleen. CONCLUSION: Pretreatment with PACAP may protect against TBI by influencing periphery T cellular immune function.

OBJECTIVETo identify the risk factors and socio-psychological condition of epilepsy in general population.

METHODSA community-based, pair-matched case-control study using the epileptic patients living in Zhujing town, Jinshan district, Shanghai was carried out. Patients were matched for age (+/-1 years) and gender to controls (81 cases and 81 controls). Data was analyzed with multiple conditional logistic regression.

RESULTSAs a result of multiple logistic regression, postnatal insults (OR = 6.517), alcohol intake (OR = 10.761) and family history (OR = 5.414) were powerfully associated with epilepsy. Compared with control group, epileptic patients were significantly different in socio-psychological condition, especially in > or = 17 years adult patients.

CONCLUSIONPostnatal insults, alcohol intake and family history were the risk factors of epilepsy. Psychological and psychiatric disorders were highly prevalent among epilepsy patients.

OBJECTIVETo evaluate the immuno-effects of hepatitis B (HB) vaccination in adults.

METHODSFive groups were sampled by means of cluster sampling, and serum HBsAg, anti-HBs and anti-HBc were tested in every group at people aged from 18 to 50. Recombinant HB vaccine was injected to the ones that HBsAg, anti-HBs and anti-HBc were all negative. Concentration of anti-HBs in serum was tested after one year and three years of vaccination. Immuno-effects of recombinant HB vaccination in adults at different ages and between sexes, were then calculated.

RESULTSGood immuno-effects of recombinant HB vaccination in adults were noticed. After one year and three years of vaccination with 5 micro g recombinant HB vaccine, the anti-HBs positive rates were 82.76%, 70.77% while the serum concentrations of anti-HBs were 55.91 mIU/ml and 35.41 mIU/ml respectively. When 10 micro g was used, the concentrations were 83.74%, 72.22%, 56.89 mIU/ml and 30.29 mIU/ml respectively. The effects did not show significant differences between different doses on 10 micro g and of 5 micro g. Concentration of anti-HBs reduced when time went by. The factors such as age and sex influenced the effects of immunity on recombinant HB vaccination.

CONCLUSIONGood immunity could be obtained when recombinant hepatitis B was vaccinated in vulnerable population aged 18 to 50.
