Objective To investigate the effects of children's mentality on mental symptoms during recovery period of ketamine anesthesia. Methods According to the mentality, forty-five children undergoing smalminor surgery were assigned into active group, stable group and fretful group with 15 cases each. Child was anaesthetized by ketamine alone. RP, BP, HR and SpO_2 were recorded at the end of operation, 5,10 and 30 min after operation. Meanwhile the expression, feeling, behavior, talking and activity were observed. Results RR, BP, HR in active group and fretful group were significantly higher than those in stable group. There was a significant difference in the expression, feeling, behavior, talking and activity among three groups. Conclusion Children's mentality has a significant effect on mental symptoms and hemodynamics during recovery period of ketamine anesthesia.

Cancer stem cell(CSC)plays a very important role in the genesis、relapse、metastasis and drug resistance of cancer.Traditional chemotherapeutics may kill a large part of malignant cells,but it has little effect on scanty CSC.It is enough for the relic CSC to make cancer relapse and metastasis.Targeted therapy aimed directly at CSC is the only way to cure cancer fundamentally.The specific biologic character of CSC is helpful for studying and developing targeted therapy to CSC.

OBJECTIVE To determine the distribution of bacterial flora in hospital infection and to provide laboratory(evidence) for controlling hospital infection and selecting rationally antibiotics in clinic practice.METHODS All(isolates) were identified by routine procedure.MRSA and ESBLs-producing rate of Escherichia coli and Klebsiella pneumoniae were(examined.) RESULTS Among all these clinical infectious specimens,there were 202 strains of Gram negative bacilli,(accounting) for 40.9%(202/495);166 strains of fungi,accounting for 33.5%;621 strains of Gram positive cocci,for 20.6%(102/495).Candida albicans,E.coli,Pseudomonas aerugionosa,C.tropicalis and C.glabrata took the first five bacteria in infection.Analysis of drug resistant bacteria suggested that the isolated rate of ESBLs-producing strains in Staphylococcus aureus be 47.6%,be CNS in MRCNS 78.1% and MRSA in SA be 42.3%.CONCLUSIONS Multidrug resistance and fungus infection are the main risk factors in our hospital.We must improve means of treatment on clinical work and use antibiotic rationally to reduce the infection rate.

Objective To develop a time saving and sensitive cell culture system based on hepatitis C virus chimera expressing enhanced green fluorescent protein(EGFP) and to facilitate the study on HCV pathogenesis and screening of anti-HCV drugs.Methods Enhanced green fluorescent protein reporter gene and a mutation V2440L that can yield higher virus titers were introduced into the C-terminus of non-structural protein 5A (NS5A) of the JFH1 viral genome by using recombinant PCR.The viral RNA was transfected into Huh7.5 cells.Viral RNA in supernatant of HCV RNA-transfected cells was determined after transfection by RT-PCR.HCV replication and infection were determined by immunofluorescence assay.IFN-α was used to evaluate the feasibility of this system for anti-HCV drugs screening.Results The viral RNA replicated efficiently in transfected cells.These cells can produce HCV-EGFP reporter virus.Viral RNA levels in supernatant were 3.06× 105 copies/ml and 7.96×106 copies/ml at 72 h and 9 d after transfection,respectively.The virus titer reached to 104 FFU/ml 9 d after transfection.The expression of EGFP was inhibited by IFN-α in a dose dependent manner in Huh7.5 cells infected by HCV-EGFP reporter virus.Conclusion The recombinant HCV JFH1-EGFP reporter gene system is a time saving,cost effective and sensitive method for studying viral replication cycles and screening of anti-HCV drugs.

ObjectiveTo develop a cell culture system with consistent expression of whole hepatitis C virus (HCV) gene and Renilla luciferase gene and to facilitate the study on HCV pathogenesis and the screening of new antiviral drugs.MethodsRenilla luciferase (RLuc) reporter gene and a mutation that could yield higher virus gene expression were introduced into the C-terminus of non-structural protein 5A (NS5A) of the JFH1 viral genome by using recombinant PCR.The viral RNA was transfected into Huh7.5 cells.Naǐve Huh7.5 cells were infected by the supernatant from the viral RNA transfected cells.HCV replication and infection were determined by virus titration,Renilla luciferase assay,immunofluorescence assay and western blotting.IFN-α was used to evaluate the feasibility of this system for anti-HCV new drug screening.ResultsThe viral RNA replicated efficiently in transfected cells.These cells could produce high titer of HCV-Rluc reporter virus and the virus titer reached to 1.5 × 104 FFU/ml at day 15 of posttransfection.The activity of Renilla luciferase was inhibited by IFN-α in a dose dependent manner in Huh7.5 cells infected by HCV-Rluc reporter virus.ConclusionThe recombinant HCV-JFH1-Rluc reporter gene system is sensitive and efficient.It can be a useful tool for high throughput screening of anti-HCV drugs.

0.05). There was only 2/109 cases (5.8%) need a second course of antibiotics because of likely infection and 102/109 cases (93.5%)need not any moor antibiotics. The mean period of antibiotic treatment in group Ⅰ, group Ⅱa and group Ⅱb were (1.2?0.5) days,(4.8?0.8) days and (9.3?1.8) days,respectively.There were significant differences(all P

In this study, OVA-induced asthma mice was taken as the model, and orally administered with different concentration of ethanol extracts of crude and processed Stemona tuberosa, in order to determine the cytokine level released from Th1 and Th2 in splenocytes. RT-PCR was carried out to determine the genetic expression of T-bet/GATA-3 in lung, and compare the differentiation between ethanol extracts of crude and processed S. tuberosa in therapeutic effect on asthma in mice. According to the results, compared with the crude samples, processed samples significantly increased the levels of inflammatory factor INF-gamma (P < 0.05) and decreased IL-5 (P < 0.05) in splenocytes. According to the RT-PCR results, the administration of processed samples could increase the ratio of T-bet/GATA-3 (P < 0.05). The experiment showed that ethanol extracts of both crude and processed S. tuberosa could treat asthma by regulating Th1/Th2 ratio, but processed samples showed more notable effect. This indicated that crude and processed S. tuberosa had significant pharmacological difference. Therefore, it was more rational to apply processed S. tuberosa in clinical treatment of asthma and chronic cough, which layed a foundation for further revealing the processing mechanism of S. tuberosa.

OBJECTIVETo study the clinical efficaly and safety of Tiepi Fengdou Granule (TFG) and Capsule (TFC) combined with chemotherapy and/or radiotherapy in treating lung cancer patients with Qi-Yin asthenia syndrome (QYAS).

METHODSEighty patients were randomly assigned into 3 groups: the TFG group (32 cases), the TFC group (32 cases) and the Shengmai Capsule control group (16 cases). Changes of symptoms of QYAS, main symptoms of lung cancer, Karnofsky scoring as well as the blood routine test were observed.

RESULTSThe total effective rate of symptom improving in the TFG group and the TFC group was 81.2% and 93.3% respectively, showing insignificant difference between the 2 groups (P > 0.05), but both were higher than that in the Shengmai Capsule control group (50.0%, P < 0.05 and P < 0.01). Additionally, as compared with those before treatment, the neutrophil count increased and the lymphocytes count obviously decreased in the TFC group after treatment (all P < 0.05).

CONCLUSIONBoth dose-forms of the remedies, TFC and TFG, have significant effects in treating lung cancer with QYAS, but with insignificant difference between them.
