Batch fermentation of lycopene by recombinant E. c ol i ZYL-2 at various temperatures ranging between 23℃～37℃ were studied in 7L fermentor. At 33℃, cell specific growth rate in earlier stage of culture was higher, and the time obtained maximum cell dry weight was shorter at other tempe rature. while after 9 h, lycopene specific production rate was higher at 28℃. Based on these results, a two-stage temperature control strategy was developed in which 33℃ was used for fermentation for the first 9 h and the temperaturew as switched to 28℃ after 9h. Using this temperature-shift strategy, the maxim al lycopene content and productivity reached 605.25?g L-1 and 28.82?g L-1h-1. The lycopene fermentation level obtained by the strategy was higher than those in single temperature-control experiments.

There are reports about the chemical compounds of Ciwujia herbs, but with no study report about the chemical material basis of Ciwujia injection (CWJI). In this study, LC-MS(n) and LC-Q-TOF-MS techniques were adopted for a qualitative analysis on phenylpropanoids in CWJI. The Ultmate XB-C18 column (4.6 mm x 250 mm, 5 microm) was adopted and eluted with the mobile phase of 0.5% formic acid-water and acetonitrile, with the flow rate at 0.8 mL x min(-1) and the column temperature at 20 degrees C. Based on the data of high-resolution and multi-stage MS, control products and literatures, altogether 54 phenylpropanoids were identified in Ciwujia Injection, including 34 phenylpropanoids, 16 ligans and 4 coumarins. Among them, 28 were reported for the first time in Ciwujia, and 14 compound structures were identified in comparison with the control products. The method established in this study could be used to simply and rapidly identify phenylpropanoids in CWJI. The findings provide scientific data for defining the chemical material basis of CWJI.

Objective To evaluate the efficacy and safety of hydroxychloroquine combined with butyli flufenamatum ointment and other drugs for the treatment of polymorphous light eruption (PLE).Methods A total of 48 patients with PLE were randomly and equally classified into group 1 and group 2.Both groups took hydroxychloroquine 200 mg twice a day and loratadine 10 mg per day for the initial 4 weeks,then took hydroxychloroquine 100 mg twice a day alone for another 4 weeks.Group 1 also topically applied butyli flufenamatum ointment twice a day during the 8 weeks,while group 2 applied mometasone furoate cream twice a day for the first 2 weeks followed by butyli flufenamatum ointment twice a day for another 6 weeks.Each treatment cycle lasted 2 weeks,and both groups received 4 cycles of treatment.Patients were evaluated for the response rate at the end of each cycle,and for the total symptom score and erythema score before and after the 8-week treatment.Statistical analysis was carried out using t test,chi-square test,Fisher's exact test and repeated-measures analysis of variance with the SPSS17.0 software.Results On day 14,28,42 and 56,the total score improved in 0,3,12 and 19 patients in group 1 respectively,and in 1,4,12 and 20 patients in group 2 respectively;the erythema score improved in 1,5,13 and 18 patients in group 1 respectively,and in 0,5,11 and 17 patients in group 2 respectively.No significant difference was observed between the two groups in response rates at any of the above four time points (P ＞ 0.05).Both the total score and erythema score significantly decreased after the 8-week treatment in both groups compared with the pretreatment scores (both P ＜ 0.05).No serious adverse reaction was observed in either of the two groups.Conclusions Hydroxychloroquine combined with loratadine and butyli flufenamatum ointment shows high efficacy and safety for the treatment of PLE.Topical butyli flufenamatum ointment is highly effective for the treatment of PLE,especially for PLE cases mainly presenting with erythema.

?ig-h_3 was first identified as a transforming growth factor-beta1-inducible gene in human lung adenocarcinoma cell line. It encodes for a secreted extracellular matrix (ECM) protein, which is thought to act on cell attachment and ECM composition. Previous study showed that ?ig-h_3 were highly expressed in human hepatoma cell lines and lowly expressed in human normal hepatic cells. The present study aimed to transfect ?ig-h_3 into 7721 cells to investigate its effect on secretion of MMPs in the transfected human hepatoma cells. Full-length ?ig-h_3 gene,cloned by reverse transcription polymerase chain reaction (RT-PCR) was inserted into the eukaryotic expression vector pEGFP-C_2. The recombinant plasmid was transfected into 7721 cells with Lipofectamine2000 and Gelatin-Zymography were adopted to detect the production of MMPs in the transfected cells. Results showed that ?ig-h_3/pEGFP-C_2 recombinant expression plasmid was successfully constructed and achieved high transfection efficiency. MMPs expression of the transfected cells was promoted significantly. These results suggest that overexpression of ?ig-h_3 promoted the production of MMPs, indicating that ?ig-h_3 may play roles in the invasive and metastatic processes of hepatoma.

Climatic droplet keratopathy(CDK), an acquired corneal degenerative disease, is characterized by oil droplet deposits and banded opacity in the pre-corneal elastic layer and stroma layer, which can severely affect the visual acuity of patients. Recently, many studies have indicated that various factors caused the occurrence and development of CDK. However, the pathogenesis and specific pathogenesis of the disease remain unclear. So this article aims to summarize four aspects of the CDK, including the epidemiological characteristics, the morphology of corneal lesions, the composition of corneal deposits and the ocular surface micro-environment, and then provide a reference for ophthalmologists to acknowledge and explore CDK deeply.

AIM: To evaluate the effect of binocular visual function training in pediatric ocular trauma. METHODS: There were 76 patients (76 eyes) that were hospitalized with a primary diagnosis of ocular injury at the Affiliated Hospital of Medical College, Qingdao University between January 2006 and December 2009. Binocular visual function training was given after primary wound repair. Far stereopsis function were checked using AIT-1000 synoptophore fusion, and near stereopsis function was checked using Titmus stereogram.Binocular visual function was compared before and after training. RESULTS: Before binocular visual function training,26 eyes（34%）had no binocular vision, after training there were only 16 eyes（21%） without binocular vision. Before undertaking binocular visual function training with fusion, only 27 eyes (36%) had binocular vision, after the training there were 48 eyes (63%) with binocular vision. Before undertaking binocular visual function training with far stereopsis ,there were 23 eyes (30%) with binocular vision, after the training there were 29 eyes (38%). Before binocular visual function training with near stereopsis, there were 14 eyes (18%) with binocular vision, after the training there were 33 eyes (43%) with binocular vision. There was a significant difference in the number of patients with binocular vision before and after binocular visual function training. CONCLUSION:The training is useful for the reconstruction of binocular visual function in pediatric ocular trauma.
