OBJECTIVE:
To investigate the influences of staphylococcus aureus in planktonic and biofilm forms on the expression of lysozyme, SLPI and gp340 in the human sinonasal explant model.
METHOD:
Mucosa samples from ethmoid sinus were collected from ten patients of cerebrospinal fluid leak and were cultured with and without S. aureus biofilms and planktonic cells. After the infection, the explant model was confirmed by CLSM, and the secretion of lysozyme, SLPI and gp340 was detected by enzyme-linked immunosorbent assay (ELISA) at 8, 16, and 24 h after S. aureus challenge. Expressions of lysozyme, SLPI and gp340 in mRNA and protein levels after 24 h S. aureus challenge were detected using RT-PCR, immunohistochemistry and Western bolt assay respectively.
RESULT:
The secretion of lysozyme, SLPI and gp340 in the explant model was observed with a trend to increase in a time-dependent manner. At 8 and 16 h after S. aureus challenge, the secretion of lysozyme, SLPI and gp340 in biofilms group was significantly higher than these in planktonic cells group and control group (P<0. 05). S. aureus biofilms enhanced the mRNA expressions of lysozyme, SLPI and gp340 significantly compared with planktonic cells and controls, and the mRNA expressions in the explant model challenged by planktonic cells were significantly higher than controls (P < 0.05). Although the Western bolt assay showed no differences between the lysozyme expression in the planktonic cells group and control group (P > 0.05), the biofilms enhanced the expressions of lysozyme, SLPI and gp340 significantly compared with planktonic cells and controls (P < 0.05).
CONCLUSION
S. aureus biofilm induced the expressions of lysozyme, SLPI and gp340 to a higher level than planktonic cells, indicating that S. aureus biofilm was an influencing factor on the innate immune system.

BACKGROUND:Stem cel therapy has been used for prevention and treatment of degenerative disc disease. Considering the special microenvironment in the intervertebral disc, the survival rate and differentiation ability of transplanted cels are decreased, which may lead to the poor efficacy of stem cel therapy. How to improve the survival ability and therapeutic effect of the transplanted cels is the focus of stem cel therapy for degenerative disc disease.
OBJECTIVE: To investigate the effects of cobalt chloride combined with hypertonic solution pretreatment on bone marrow mesenchymal stem cels that wil be transplanted for treatment of degenerative disc disease.
METHODS:(1)In vitro cel experiment: bone marrow mesenchymal stem cels were divided into three groups and subjected to normal culture medium (normal control group), 1% hypertonic mother solution (hypertonic group), 100 μmol/L cobalt chloride (hypoxia group), or 1% hypertonic mother solution plus 100 μmol/L cobalt chloride (combined group) for 1 week. Then, 2% hypertonic solution and 200 μmol/L cobalt chloride cobalt chloride were used to simulate the anaerobic and hypertonic environment intervenes in pretreated and untreated bone marrow mesenchymal stem cels for 24 hours. After that, RT-PCR was used to detect the expression of caspase-3 for apoptosis evaluation. (2)In vivo animal experiment: Sprague-Dawley rats were divided into model, cel transplantation and hypertonic plus hypoxic groups. Rat models of intervertebral disc degeneration were made in these three groups. After modeling, rats in these three groups were given no treatment, bone marrow mesenchymal stem cel transplantation or transplantation of bone marrow mesenchymal stem cels which were subjected to hypertonic and hypoxia pretreatments into the intervertebral disc. Two weeks later, immunohistochemistry and RT-PCR methods were used to detect cel distribution and related gene expression, respectively, thereby to evaluate the therapeutic effect of stem cels.
RESULTS AND CONCLUSION: (1)In vitro cel experiment: caspase-3 mRNA expression was significantly reduced in pretreated bone marrow mesenchymal stem cels compared with the untreated cels (P < 0.05). (2)In vivo animal experiment: compared with the control group, the caspase-3 and interleukin-1β in the intervertebral disc and a number of degenerative indexes were decreased in the cel transplantation. Compared with the cel transplantation group, these indicators had better outcomes in the hypertonic plus hypoxic group (P < 0.05). These findings indicate that bone marrow mesenchymal stem cels have therapeutic potential for degenerative disc disease, and have better adaptability and transplantation effects by hypertonic and hypoxia pretreatments.

To ensure the stability of chemistry components and the convenience of operation, ultrasound method was chosen to study in this investigation. As the total common peaks area in chromatograms was set to be evaluation index, the influence on the technology caused by extraction time, ethanol concentration and liquid-to-solid ratio was studied by using single factor methodology, and the extraction technology of Paeoniae Radix Alba was optimized by using response surface methodology. The results showed that the extracting results were most affected by ethanol concentration; liquid-to-solid ratio came the second and extraction time thirdly. The optimum ultrasonic-assisted extraction conditions were as follow: the ultrasonic extraction time was 20.06 min, the ethanol concentration in solvent was 72.04%, and the liquid-to-solid ratio was 53.38 mL · g(-1), the predicted value of total common peaks area was 2.1608 x 10(8). Under the extraction conditions after optimization, the total common peaks area was 2.1422 x 10(8), and the relative deviation between the measured and predicted value was 0.86%, so the optimized extraction technology for Paeoniae Radix Alba is suitable and feasible. Besides, for the purpose of extracting more sufficiently and completely, the optimized extraction technology had more advantages than the extraction method recorded in the monogragh of Paeoniae Radix Alba in Chinese Pharmacopoeia, which will come true the assessment and utilization comprehensively.

OBJECTIVETo compare efficacy of unilateral external fixators and locking compression plates in treating type C fractures of the distal radius.
METHODSFrom January 2009 to June 2010, 76 patients with distal radius fracture were treated with LCP and external fixators, 54 patients were followed up. Among them, 29 cases were male and 25 cases were female with an average age of 45.31 (ranged, 24 to 68) years old. There were 29 patients in LCP group. According to AO classification, 8 cases were type C1, 7 cases were type C2 and 14 cases were type C3. There were 25 cases in external fixators group. According to AO classification, 6 cases were type C1, 8 cases were type C2 and 11 cases were type C3. Radial height, volar tilt and radial inclination were compared, advanced Gartland-Werley scoring were used to assessed wrist joint function after 6 and 12 months' following up.
RESULTSTwo cases were suffered from nail infection in external fixators group. Fifty-four patients were followed up from 12 to 24 months with an average of 21.3 months. Radial height was (9.60 +/- 0.72) mm, volar tilt was (9.55 +/- 0.80) degrees and radial inclination was (21.40 +/- 0.78) degrees in LCP group,while those were (9.40 +/- 0.70) mm, (9.47 +/- 0.71) degrees and (21.20 +/- 0.73) degrees in external fixtors group, and with no statistical significance (P>0.05). Advanced Gartland-Werley score after 6 months' following up was 3.31 +/- 1.17 in LCP group, 5.56 +/- 1.58 in external fixtors group, and with significant difference (t=-5.99,P<0.05); after 12 months' following up, advanced Gartland-Werley score was respectively 2.66 +/- 1.01 and 3.08 +/- 1.00, but with no statistical meaning (t=-1.55, P>0.05).
CONCLUSIONLCP and external fixtors can receive good curative effects in treating type C distal radius fracture, and LCP can obtain obviously short-term efficacy, while there is no significant difference between two groups in long-term results. For serious distal radius comminuted fracture which unable to plate internal fixation, external fixators is a better choice.
