In 54 cases of pulmonary hypertension, the PaCO2 was markedly lowered, PaO2 and SaO2 elevated, HR, CO and mPAP, PVR all lowered in the treatment group (P0. 05), but SBP was significantly different (P

OBJECTIVE:To study the stability of the mixture of cefradine for injection and ornidazole sodium chloride injection.METHODS:HPLC method was adopted in which the Nova-pak C 18 was taken as the chromatographic column,methanol-water(35∶65)was taken as the mobile phase with detection wavelength at240nm.The contents were determined after mixing of cefradine for injection and ornidazole sodium chloride injection under the room temperature within8hours,and the appearance of the solution was observed and its pH value was determined.RESULTS:No significant differences were found in terms of the appearance,pH value and the contents of the mixed solution.CONCLUSION:The mixture of ornidazole for injection and cefradine sodium chloride injection can be used under room temperature within8hours of mixing.

Objective: To explore the influence of silencing Survivin expression by RNA interference on the radiosensitivity of cervical carcinoma SiHa cells. Methods: The recombinant eukaryotic expression plasmid pSurvivin-shRNA was constructed and transfected into SiHa cells. The mRNA and protein expressions of Survivin were determined by RT-PCR and Western blotting, respectively. The activity of caspase-3 was measured by kinase activity determination method. The apoptotic rate was determined by flow cytometry. The changes of radiosensitivity were explored by colony formation test. Results: Compared with SiHa cells transfected with pNeg-shRNA (SiHa/ pNeg-shRNA cells) and untransfected SiHa cells, the expressions of survivin in the cells transfected with pSurvivin-shRNA (Si-Ha/ pSurvivin-shRNA cells) were inhibited significantly at both mRNA and protein levels. The activity of caspase-3 in SiHa/pSurvivin-shRNA cells was significantly enhanced, and the D405 was 1.34 ± 0.05 (P < 0.05). The apoptotic rate of SiHa/pSurvivin-shRNA cells was (5.13 ± 0.81)% and (11.27 ± 1.89)% after 24 hand 48 h X-ray irradiation at 6 MV and 8 Gy, respectively, which was significantly higher than SiHa/pNeg-shRNA cells and untransfected cells (P < 0.05). The colony formation ability of SiHa/pSurvivin-shRNA cells was markedly decreased after irradiation (P < 0.05), which indicated that the sensitivity of SiHa/pSurvivin-shRNA cells was enhanced. Conclusion: The inhibition of Survivin by RNAi could enhance the radiosensitivity of SiHa cells by increasing caspase-3 activity and inducing apoptosis.

The effect of traditional therapy is limited for liver cancer,gene therapy gets more and more recognition in recent years.Oncolysis virus is a kind of conditionally replicating virus,with special reproductivity in cancer cells,and then kills them.Gene agents are usually introduced into tumor tissue by intra-tumor and intra-arterial injection,and the technique of interventional therapy is able to satisfy the demand excellently.So,some breakthrough is expected in treating liver cancer by skillfully combining oncolysis virus and interventional technique

In order to investigate the role of antiapoptosis gene, survivin in the resistance to palcitaxel, the expression of survivin mRNA and protein in the process of paclitaxel treatment in breast cancer cell line MCF-7 was detected MCF-7 cells were incubated with paclitaxel at different concentrations. The growth inhibition rate of MCF-7 was investigated by tetrazolium bromide (MTT) colorimetry. The change of apoptosis was detected by Annexin-V/PI methods. The changes in the expression of survivin mRNA and protein were studied by reverse transcription polymerase chain reaction (RT-PCR) and Western-blot assay respectively. The growth inhibition rate of MCF-7 was increased in a concentration-and time-dependent manner. Paclitaxel of higher concentration could effectively induce apoptosis in MCF-7 cells after 48 h, while the expression of survivin was increased at early time (within 6 h) and decreased after 24 h regardless of treatment concentrations of paclitaxel. It suggested that tumor cells might evade the paclitaxel-induced cell cycle arrest and apoptosis by increasing the level of survivin at early treatment time.

Objectiye To investigate the relationship between dementia degree of multi - infarct dementia(MID)and CT findiugs. MethodThe volume and location of focal lesion as well as the presence of cerebral atrophy in 44 MID patents with mild dementia, 40 MID patients withmoderate dementia, 38 MID patients with severe dementia were compared. Result The volume of focal lesion correlated with dementia degreeof MID. The bigger the volume was, the heavier the dementia was. The cerebral atropohy was heavier in patients with severe dementia than thatin patients with other dementia. Dementia degree of MID should no correlation with the location of focal lesion. Conclusion The volume andcerebral atrophy were important the factor for determing dementia degree of MID.

Hedgehog( Hh)signaling pathway is evolutionarily conserved in vertebrates,its excessive activation is associated with abnormal cell differentiation, over proliferation, apoptosis resistance and promotion of invasion and metastasis of tumor cells. Hh signaling pathway involves in the formation and maintenance of esophageal columnar epithelium in embryonic stage,however,undetectable or barely expressed in matured esophageal squamous epithelium. Studies have shown that esophageal Hh signaling pathway can be activated by gastric acid and bile salts. Aberrant activation of Hh signaling pathway can cause the gradual transition of squamous epithelium to columnar epithelium and intestinal-type epithelium,ultimately induces the occurrence of Barrett’s esophagus( BE). Therefore,targeted inhibiting the Hh signaling pathway may be a new strategy for the treatment of BE. This article reviewed the advances in study on Hh signaling pathway in the pathogenesis of BE.
