Objective To investigate the expression of matrix metalloproteinase 7(MMP7)in paraquat(PQ)?induced pulmonary fibrosis in rats. Methods Forty?eight SD rats were randomly divided into the control group and the pulmonary fibrosis model group(PQ model group),each group of twenty?four rats. Rats in the PQ model group received single intraperitoneal injection of 4 mg/mL PQ dilute solution and the control group were in?traperitoneal injected with the same dose of saline. Eight rats of each group were sacrificed on day 7,day14 and day 28 respectively. The pathological changes of lung tissues were observed and the hydroxyproline(HYP)content in lung tissues was determined. The severity of pulmonary fibrosis was observed. The expressions of MMP7 in lungs were observed by immunohistochemistry. Results The observation of general state of the experimental animals showed that except one rat died at day 28 d,all other rats survived to the end point of observation. After intraperitoneal injection with PQ,the weight of rats in the PQ model group gradually declined,and then increased around day 14,yet still much lower than that in the control group at day 28(P<0.05). After intraperitoneal injection with PQ,the pulmonary index in the model group increased gradually and then decreased after reach?ing the peak on day 14. The content of HYP in rat lung tissues in the PQ model group was remarkably higher than in the control group at day 7,day 14,and day 28,with statistical significance(P<0.01). In the PQ model group,the content of HYP was significantly up?regulated with the extension of infected time and reached the peak value at day 28. The results of HE staining showed significant pulmonary alveolitis at day 7,hyperplasia of abundant collagen fibers in alveolar septum at day 14,and obvious pulmonary fibrosis and collapse of alveolar structure on day 28 in the lung tissues of the PQ model group. A weak expression of MMP7 was measured in the lung tissues in the control group and the expression of MMP7 was higher in the PQ model group than in the control group at day 7,day 14,and day 28,with statistical significance(P<0.05). Conclusion Paraquat poison?ing was mainly manifested in inflammatory reactions of lung tissues in the early stage together with increase of fibroblasts and mainly in fibrosis in the late stage. The expression of MMP7was increased along with the severity of pulmonary alveolitis or fibrosis and showed significant changes compared to the control group at day 28 after poisoning,indicating that MMP7may be the marker of paraquat?induced pulmonary fibrosis.

Objective To compare the short-term and long-term efficacy of chemotherapy with biotherapy and same chemotherapy followed by biotherapy on malignant melanoma in stage Ⅲ and Ⅳ.Methods 82 cases with malignant melanoma were treated with chemotherapy(dacarbazing,cis-platin and carmustine)or biotherapy(interleukin-2,interferon ? and dendritic cell vaccine)or biochemotherapy(chemotherapy plus biotherapy).Among them,32 cases were received biochemotherapy,26 for biotherapy and 24 for chemotherapy.Therapentic response was assessed every 3 cycles.The median time of follow up was 2 years(1-4 years).Results Response rate was 71.9% for biochemotherapy,46.2% for biotherapy and 54.2% for chemotherapy(P

Abtract: Acute coronary syndrome is a common clinical and frequently occurring disease, belonging to the chest discomfort, heartache, and true heart pain of TCM category. The clinical observation shows that the heat and blood stasis, and poison damage heart nutrient is one of the important mechanisms of triggering coronary syndrome. Therefore, the method of promoting blood circulation to remove meridian obstruction and the Qing Ying detoxication was established as the basic treatment, and Danshen Tongluo Jiedu Decoction is applied as the main formula. According to the different types of disease and syndrome differentiation, flexible modification can achieve good efficacy. It is expected that these will provide new ideas and methods for clinical treatment of acute coronary syndrome.

Objective To explore the effect of the simvastatin administration on the expression of connective tissue growth factor （CTGF） in fihrotic lungs of rats. Methods The cats were treated with single intratracheal instillation of bleomycin （BLM） or instillation of the same volume of normal saline （NS） as a control. The administration of simvastatin（20 mg/kg）began once a day immediately or 7 days later after intratracheal BLM instillation respectively with the same volume of NS was given as a vehicle control. The rats were killed on day 7,14 and 28 respectively. Pathological alteration of lung tissue was observed hy HE staining and Masson staining. Hydroxyproline（HYP）content in lung tissue was used to determine the severity of pulmonary fibrosis. The expression of CTGF in lung tissue was exanfined by immunohistochem- istry staining and photodeusitometry. Results Histopathological changes of pulmonary fibrosis emerged gradually after the instillation of BLM. The expression level of CTGF was increased in lungs of rats after intratracheal instillation of BLM, compared with the control. The administration of simvastatin immediately or 7 days after intratracheal instillation of BLM, attenuated the histopathological changes of bleomycin- induced puhnonary fibrosis and prevented the increased expression of CTGF in lung tissue on day 28. Conclusion The adntinistration of simvastatin, immediately or 7 days after intratracheal BLM instillation, prevented the up-regulation of CTGF in fibrotic lungs of rats, which ntight be one of the mechanisms of the anti-fihrosis of simvastatin in lungs.

The intraspecies quorum sensing system of Streptococcus mutans is involved with com genes family.ComE is a kind of response regulator and act as a promoter to the quorum sensing genes.S.mutans comE mutant strain IFD140?comE was constructed using the inframe-deletion system via twice homologous recombination.In current genetic studies of S.mutans,insertion duplication and allelic exchange mutagenesis techniques routinely create polar effects to downstream genes.In-frame deletions are essentially free of these polar effects because the mutation does not introduce any genetic markers.By PCR,sequencing and RT-PCR,it was confirmed that IFD140?comE has only 717bp deleted within the comE gene and the transcription of the downstream gene comD was not interfered.The research of the morphological characteristics indicated that IFD140?comE formed clumps and cells accumulated at the bottom of the glass tubes and light-microscopic observations displayed that the mutant strain formed significantly longer chains compared to those formed by the wild strain.The successfully construction of IFD140?comE lay a foundation for further quorum sensing research.

Purpose:To study the response and toxicity of the regimen of oxaliplatin combined with fluorouracil and calcium folinate in the treatment of consisting of advanced colorectal cancer.Methods:Thirty-seven patients with advanced colorectal cancer received chemotherapy of regimen:oxaliplatin 130 mg/m~2 2 hours iv on day 1,calcium folinate 200 mg/ m~2 iv 2 hours on days 1 to 5,followed by fluorouracil 300 mg/m~2(≤500 mg/d) iv 4 h on days 1 to 5,three or four weeks as one cycle.Results:The total response rate was 29.7%,the main toxicity was bone marrow suppression and neuro-sensory toxicity,leukopenia was observed in 45.9% of the patients,but grade Ⅲ and Ⅳ in only 8.1%,neuro-sensory toxicity was observed in 81.9.%,but grade Ⅲ and Ⅳ in only 5.4%.Conclusions:This study shows that the regimen of oxaliplatin combined fluorouracil and calcium folinate is effective and tolerable in advanced colorectal cancer therapy.
