Objective To investigate the value of C- reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-?) in early diagnosis of neonatal sepsis. Methods Sixty- five newborns were divided into experiment group and control group, experiment group was also divided into sure group and doubtful group by blood culture We assessed the level of serum CRP, IL-6 and TNF-? in 24 hours and after 24 hours of clinical diagnosis of sepsis in experiment group, and examined the blood culture before antibiotic treatment Serum CRP, IL-6 and TNF-? were also examined in 3 to 6 days old. Results 1 The levels of serum CRP, IL-6 and TNF-? in experiment group were significantly higher than that in control group 2. The sensitivity of IL-6 and TNF-? were higher than CRP in 24 hours in experiment group. 3. After 24 hours, the sensitivity of CRP was elevated,and there was no statistical difference compared with the IL-6. Conclusion IL-6 and TNF-? are the credible marker in the early diagnosis of neonatal sepsis, and are more sensitive than the CRP, the IL-6 is the first sensitive marker.

Procalcionin ( PCT) is a soluble protein liberated into the circulation of patients in response to severe systemic in-fection, in particular by bacterial infection.It is used as the most accurate biomarker for the diagnosis of sepsis.This review briefly de-scribes the induction of PCT, the comparison of PCT and other markers of sepsis, the application of PCT measurement in confirmation or exclusion of diagnosis of sepsis, the assessment of severity and treatment effectiveness of systemic infection, the application of PCT in guiding individual and specific treatment of antibiotics, and the anormaly situation of elevated levels of PCT in patients who do not have sepsis.

Objective To provide reference for clinical pharmacist participating in management of nausea and vomiting induced by tumor chemotherapy. Methods The process of pharmaceutical care for a patient with severe vomiting caused by adjuvant chemotherapy after gastric cancer operation was described. Antiemetic application and drug adverse reactions were analyzed. A new treatment plan was given by clinical pharmacist. Results The suggestions were adopted by clinician. The vomiting was controlled and drug adverse reactions were dealt with. Conclusion To reduce the risk and improve the income of antiemetic,clinical pharmacists should pay more attention to clinical practice guideline,drug interaction and adverse reactions, provide the most suitable suggestions for clinicians according to pharmacology and evidence-based medicine.

Objective To explore the enhancement effect of caffeine in cisplatin-induced apoptosis of osteosarcoma cell line OS-U2. Methods The osteosarcoma cells were incubated with different concentrations of cisplatin (0.2, 2, 5, 10 and 20?g/L), caffeine (0.2, 2.0mmol/L) and caffeine + cisplatin for 24, 48 and 72 hours. The proliferation of OS-U2 cells was determined by MTT assay, the apoptotic levels were determined by flow cytometry (FCM), and the morphologic changes of apoptotic cells and the positive rates of apoptosis were determined by fluorescence microscopy. Results The proliferation of OS-U2 cells was inhibited, and the apoptotic level was increased when incubated with caffeine and/or cisplatin. There were dose- and time-effect relationships between the lethal effect of cisplatin on osteosarcoma cells and caffeine. Conclusion There is a remarkable enhancement effect of caffeine on cisplatin-induced apoptosis of osteosarcoma cell line OS-U2. It seems that the apoptosis-inducing activity of caffeine may enhance the lethal effect of cisplatin on osteosarcoma cells.

The most of secreted proteins are exported by Sec translocase (secretion pathway). SecA ATPase is one of the most important subunit in the Sec translocase, which is preprotein translocase nanomotor that undergo membrane insertion and deinsertion to drive preprotein across the bacterial inner membrane, and SecA is indispensable to bacteria. It should be presumed that the compound which inhibits the activity of SecA ATPase probably can be used as the candidate of bactericide. A secA gene from Pseudomonas aerugi- nosa PAO1 was amplified and expressed in Escherichia coli BL21.19 (secA13). It has been shown that the wild-type SecA of Pseudomonas aeruginosa could fully complement the E. coli amber (secA13) mutant at the non-permissive temperature. So a cell level screening model targeting on SecA was established based on the above result. The inhibition of PaSecA ATPase activity was applied to validate the specificity of the cell-based method. Two positive samples based on both of cell and enzyme activities will be further studied.

PPP2R5C is one of the members of regulatory subunits of protein phosphatase 2A (PP2A), which plays a critical role in cell proliferation, differentiation and transformation, based on its induction of dephosphorylation of P53 at various residues. Recently, it was characterized that the alteration of expression pattern of PPP2R5C is associated with cell malignant transformation, thus PPP2R5C was thought as a marker for progressive disease in B-CLL. In this article the gene structure and biological function of PPP2R5C as well as relation of PPP2R5C with genesis and development of cancer were discussed.

In this experiment, the HPLC specific chromatogram was adopted, with Agilent Extend-C18 (4.6 mm x 250 mm, 5 microm) as the chromatographic column, and 0.5 per thousand trifluoroacetic acid and acetonitrile as the mobile phase for gradient elution, so as to establish specific chromatograms for drug pair of Schizonepetae Herba and Saposhnikoviae Radix from different producing area, identify 12 common characteristic peaks, and obtain the comparison specific chromatography of drug pair of Schizonepetae Herba and Saposhnikoviae Radix. The method is simple, accurate and highly reproducible, and thus can be used as the basis for the quality control of the drug pair.
