The effects of surfactants on the production of cellulase by Trichoderma viride in liquid substrate fermentation process were investigated. Straw was used as the sole carbon source and the surfactants were biosurfactant rhamnolipid from Pseudomonas aeruginosa and Tween 80. The changes of FPA,CMCase,Avicelase and surface tension with time were analyzed under different concentrations of the two surfactants. The results showed that the surfactants can enhance the enzyme activity of Trichoderma viride. The FPA,CMCase,Avicelase were promoted 1.08,1.6 and 1.03 times higher than the controls by rhamnolipid. The enhancement of the enzyme activity by rhamnolipid was much higher than that of Tween 80. At the same time,rhamnolipid was not degraded prior to other substrate.

AlM:To evaluate the efficacy of combined pranoprofen eye drops and artificial tears on the treatment of mild to moderate dry eye syndrome after trabbeculectomy.METHODS:This prospective case control study included 63 cases (63 eyes) of patients with mild to moderate dry eye syndrome after trabbeculectomy in our hospital from November 2013 to June 2013. All subjects were randomly divided into two groups. Observation group was treated with combined pranoprofen eye drops and artificial tears and control group received simple artificial tears marking the eyes at 1, 2, 4wk. The patient's symptoms, signs, BUT, S▏t, and FL were observed before treatment and 1, 2, 4wk after treatment.RESULTS: After 2wk, the symptoms of observation group were improved, there was statistically significant difference (P<0. 05). FL difference of each group was statistically significant ( P<0. 05 ); After 4wk, symptoms and signs were improved. There was statistically significant difference ( P < 0. 05 ). The BUT of the observation group and corneal FL scores of two groups showed significant differences (P<0. 05). CONCLUSlON: Artificial tears joint pranoprofen eye drops has good curative effect in the treatment of mild to moderate dry eye syndrome after trabbeculectomy.

Objective To explore a more reasonable and effective therapeutic regimen and evaluate prognostic factors in hepatoblastoma patients after combined therapy.Methods Sixteen patients diagnosed on hepatoblastoma between Jan.2000 and Nov.2007 were reviewed and followed-up.Resection with chemotherapy was taken among 16 cases.Chemotherapy included pre-operation and post-operation.Five cases were cured by transcatheter arterial chemombolization(TACE).Six cases were cured by single chemotherapy(both TACE and single chemotherapy were taken in 2 cases).Five cases weren't cured by pre-operation chemotherapy.Nine cases were subjected to curative resection,3 cases to alleviative resection,2 cases with single chemotherapy,1 case with single TACE,and 1 case refused operation and left hospital.Their mean survival duration was 13.5 months(3-98 months).SPSS 13.0 software was used to analyze the data.Results The total survival rate of cases as stage Ⅳ as lower than cases as stage Ⅰ,Ⅱand Ⅲ.Both alpha-fetoprotein(AFP)100 000 ?g/L cases had worse survival rate.The prognosis of mixed type was better than fetal type,embryonal type and anaplasia type.The survival rate of cases with standard chemotherapy was higher than cases with unstandard chemotherapy.And the surgical resection cases had better survival chance than non-surgical resection cases.The survival rate of surgical residual cases was worse than non-surgical residual cases.Conclusions Chemotherapy can improve the total survival rate and long-term survival rate of hepatoblastoma patients.TACE is a safe and effective choice for hepatoblastoma patients.We need to be alert and make the diagnosis as early as possibe,and treat it early and properly.

Objective: To observe the clinical effect of Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method versus ordinary acupuncture on superficial fascia for treating neck type cervical spondylopathy in Kyrgyz. Methods:A total of 64 Kyrgyz patients conforming to the diagnostic criteria of neck type cervical spondylopathy were included. The patients were randomized into a Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and a conventional acupuncture group, with 32 cases in each group. Patients in the Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were treated with Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method to stimulate the superficial fascia, the stimulation sites were primarily located at bilateral sides of the cervical vertebra as well as the trigger points in shoulder-neck region; patients in the conventional acupuncture group were punctured at the same acupoints, with twirling reducing method, and the depth of insertion was determined by the treated region. Patients in both groups received treatment every day for a succession of 5 d as a course, with a 2-day interval between 2 courses, and the whole treatment lasted for 3 courses. After 3 courses of treatment, the McGill pain questionnaire (MPQ) and neck disability index (NDI) were measured to compare the clinical effect between the two groups. Results: After treatment, scores of MPQ and NDI scale dropped when compared with those before treatment, and the differences showed statistical significance (allP<0.05); scores of MPQ and NDI in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were substantially lower than those in the conventional acupuncture group, and the differences showed statistical significance (allP<0.05). The total effective rate was 96.9％ in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and the cured rate was 78.1％, which were higher than 81.3％ and 40.6％ in the conventional acupuncture group, and the differences showed statistical significance (bothP<0.05). Conclusion: Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method by stimulating superficial fascia to treat cervical spondylopathy in Kyrgyz can produce a better clinical effect than conventional acupuncture treatment, and is effective in improving pain and stiffness in patients, and thus is worth clinical popularization.

Natural killer T-cell lymphoma (NKTL) is a malignant neoplasm which usually involves the nasal cavity or paranasal sinuses, while an orbit origin is extremely rare. Here we report the clinical, radiological and histopathologic features of a patient with NKTL originating from the orbit. We analyzed the clinical and radiologic records in the whole course of the disease. We also reviewed the morphology and immunohistochemistry of the neoplasm biopsy, including the presence of CD56, CD3 and cytotoxic molecules. This case demonstrated that nasal-type NKTL with a poor prognosis can originate from the orbit.

OBJECTIVETo explore the role of TBX3 gene in the pathogenesis of breast cancer.

METHODSThe total RNA of 51 fresh breast cancer tissues and the corresponding adjacent tissues were extracted and reverse transcribed into cDNA to detect the expression of TBX3 mRNA by real-time PCR. The correlation between TBX3 mRNA expression and the clinicopathologic parameters in relation to breast cancer metastasis was analyzed.

RESULTCompared to that in the adjacent tissues, the expression of TBX3 mRNA was markedly increased in breast cancer tissues. TBX3 mRNA expression was significantly higher in metastatic breast cancer than in non-metastatic tumors.

CONCLUSIONIncreased expression of TBX3 mRNA suggests the involvement of TBX3 in the pathogenesis and metastasis of breast cancer.

OBJECTIVETo explore the role of abnormal Tbx3 expression in the pathogenesis of breast cancer.

METHODThe total RNA of 4 breast cancer cell lines and 5 normal breast samples was extracted by routine Trizol method. After reverse transcription of the total RNA into cDNA, Tbx3 mRNA expression was detected in these samples by real-time PCR. Immunohistochemistry was used to examine the differences in Tbx3 protein expression between 60 breast cancer samples and 34 normal breast tissue samples.

RESULTSCompared to normal breast tissue samples, the breast cancer cell lines showed markedly increased Tbx3 mRNA expression. The results of immunohistochemistry demonstrated a significant upregulation of Tbx3 protein expression in the 60 breast cancer tissues in comparison with the normal breast tissues, as was consistent with Tbx3 mRNA expressions in these tissue samples.

CONCLUSIONSThe mRNA and protein expressions of Tbx3 are markedly upregulated in breast cancer cell lines and tissue samples, suggesting that Tbx3 may serve as one of the malignant biomarkers in the pathogenesis of breast cancer.

The effect of magnetic Fe3O4 particles on cellulase in the enzymatic hydrolysis of sunflower seed hull was studied in different adding ways and additive amount. In the process of enzymatic hydrolysis of sunflower seed hull, the variations of cellulase activity, reducing sugar concentration and cellulose conversion were evaluated. After the reaction, the analysis of pH and surface tension of hydrolysate were also used to determine the mechanisms of cellulase by the magnetic effect. The results indicated that after adding magnetic Fe3O4, the cellulase activity, reducing sugar concentration and conversion of cellulose had an increased between the 0.5 g/L and 2.0 g/L cases after 48 h. When the additive amount of magnetic Fe3O4 was 2 g/L, the cellulase activity at 60 h was improved significantly by 25.9%. It was found that the concentration of reducing sugar was increased from 6.950 mg/mL to 8.775 mg/mL with magnetic Fe3O4 1.5 g/L. Simultaneously, compared with the blank, which the conversion of cellulose was 47.932%, the maximum celluloseconversion of samples with adding magnetic Fe3O4 was 60.531%. Besides, the stability of cellulase activity adding in times was better than in one time. After the reaction, the final surface tension of hydrolysate with 1.5 g/L magnetic Fe3O4 was the lowest in comparison with the blank. However, no significant differences were observed in the final pH of the hydrolysate.
