Bacterial biofilm is responsible for a wide variety of nosocomial infections.Many chronic infectious diseases are closely correlated with biofilm formation in the clinic.As the biofilm growth,bacterial clusters detachment and dispersal from mature mixed-species biofilms will result in repeated acute infections.Here reviews three distinct biofilm dispersal strategies: swarming dispersal,clumping dispersal and surface dispersal.Many factors,such as heredity and increased fluid shear in the environment,contribute to this complex and dynamic process.Fundamental investigation upon biofilm will benefit clinical therapy of biofilm-associated infections.

Aurora-B as an important kinase to adjust the cell normal mitosis is a potent target for cancer treatment. Aurora-B is overexpressed in a broad range of tumor and tumor cells are more sensitive while Aurora-B is inhibited. Due to the key role of the Aurora-B in cell mitosis, the development of its inhibitors is becoming more and more important. Several small molecules inhibit with a similar efficacy both Aurora-A and Aurora-B, however, in most cases the effects resemble Aurora-B disruption by genetic methods, indicating that Aurora-B represents an effective therapeutic target. There were several Aurora-B kinase inhibitors which had entered the clinics and displayed good antitumor activity. In this review, we will outline the functions of Aurora kinase B in normal cell division and in malignancy. We will focus on recent preclinical and clinical studies that have explored the mechanism of action and clinical effect of Aurora-B inhibitors in cancer treatment.

AIM: To study the clinical characteristics of corneal perforation ( CP) .
METHODS:A retrospective analysis in July 1995 to July 2010 the First Affiliated Hospital of Fujian Medical University diagnosed CP 72 patients ( 72 eyes ) , clinical characteristics of all the patients were analyzed.
RESULTS: The incidence of corneal ulcer perforation rised year by year, the morbidity of male and female was 17:7, the onset age focused on 48 years old. Of 23 industrial workers ( 32%) with clear history of trauma, pathogeny identification results:top two:fungal infection and Acanthamoeba keratitis. A using history of glucocorticoid was found in 10 cases.
CONCLUSION:There are plenty of primary causes of CP such as traumas, fungal infection, Acanthamoeba keratitis, eroded keratitis, etc. CP happens in middle-aged males in Fujian province, most traumas are the causes, the main pathogenic bacteria is fungal infection.

UNLABELLEDOBJECTIVE; To evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) of qi-yin deficiency phlegm-stasis inter-obstruction syndrome (QYDPSIOS), and to observe its effect on inflammatory factors and fibrinolytic factors.

METHODSBy adopting a randomization grouping, parallel control, and prospective study, 73 T2DM patients of QYDPSIOS were assigned to two groups by random digit table, the Pioglitazone Tablet group (36 cases, as the control) and the JTXZC group (37 cases). All patients maintained their basic therapies and lifestyle as previous after recruitment. Patients in the JTXZC group took JTXZC, 4 pills each time, three times per day, while those in control group took Pioglitazone Tablet, 15 mg each time, once daily. The therapeutic course for all was 8 weeks. The body weight (BW), the height, body mass index (BMI), waist circumference (WC), hip circumference, waist-to-hip ratio (WHR), and scoring of Chinese medicine (TCM) symptoms were observed. Levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h PBG), glycated hemoglobin (HbA1c), tumor necrosis factor alpha (TNF-alpha), nuclear factor kappaB (NF-kappaB), and plasminogen activator inhibitor 1 (PAL-1) were detected. The safety indices such as liver and renal functions and adverse reactions were also observed.

RESULTSCompared with before treatment, BW, BMI, HbA1c, and PBG were obviously lower after 8-week treatment than before treatment in the JTXZC group (P < 0.05). There was no statistical difference in post-treatment BW, BMI, HbA1c, or 2 h PBG between the two groups (P < 0.05). Compared with before treatment, levels of TNF-alpha and PAI-1 were lowered after 8 weeks of treatment in both groups (P < 0.01). The level of NF-kappaB was obviously lowered after 8 weeks of treatment in the control groups (P < 0.05), but it also decreased in the JTXZC group with no statistical difference. The scorings of CM symptoms were somewhat improved after treatment in the two groups (P < 0.01). Besides, better effects were obtained in the JTXZC group (P < 0.05). No severe adverse event occurred in either group during the whole therapeutic course.

CONCLUSIONSJTXZC showed similar therapeutic effect to pioglitazone. Both of them could effectively improve patients' clinical symptoms, the inflammation and fibrinolytic activities in different pathways, with no severe adverse reaction.

The secondary development of traditional Chinese medicines (TCMs) is an important content of TCM modernization process, as well as an important path for developing new TCM drugs. Under the guidance of the system theory, in response to the lack of the overall guideline and practical methods for the secondary development of TCMs at present, we introduced the overall thought of the secondary development of major TCM varieties, as well as the roles and contents of clinical research, pharmacology and pharmaceutics in the process of the secondary development of major TCM varieties, so as to provide systematic strategies and methods for the development of major TCM varieties.
