Objective To investigate the effect of pvdQ(PA2385)gene on Pseudomonas aeruginosa swarming motility.Methods The plasmid pME6032 with pvdQ gene was constructed and identified,then transformed into Pseudomonas aeruginosa PAO1 using the eleetroporation to build pvdQ-overexpression strain.The pME6032-PAO1 strain was constructed with the same method.The cloning plasmid pEX18Gm containing sacB was successfully used to construct unmarked deletion mutant of pvdQ gene and pvdQ mutant strain. Bacteria were inoculated in LB and were cultured overnight.The clones were measured for the diameter of the swarming zone.The statistical analysis was done using one-factor ANOVA.Results Strains of pvdQ-overexpression and pvdQ-mutant were successfully constructed and confirmed by polymerase chain reaction(PCR).The four strains were compared for the swarming motility by changes in diameter:PAO1(20.52±1.80)mm,pME6032-PAO1 strain(19.39±2.10)mm,pvdQ-overexpression strain(51.20±2.16)mm,pvdQ-mutant strain(3.30±0.55)mm.The diameter of pME6032-PAO1 strain was not significantly different from that of wild strain PAO1(t=-0.1493,P>0.05).However,the diameter of pvdQ(Q-mutant strain was significantly shorter than that of wild strain PAO1(t=2.8525,P<0.05).while the diameter of pvdQ-overexpression strain was longer than that of the wild strain PAO1(t=1.4230,P<0.05).Conclusions pvdQ gene may be involved in regulating the swarming motility of Pseudomonas aeruginosa,which can promote Pseudomonas aeruginosa swarming motility.

Bibenzyl is a type of active compounds abundant in Dendrobium. In the present study, we investigated the inhibitory effects of six bibenzyls isolated from Dendrobium species on vascular endothelial growth factor (VEGF)-induced tube formation in human umbilical vascular endothelial cells (HUVECs). All those bibenzyls inhibited VEGF-induced tube formation at 10 micromol x L(-1) except tristin, and of which moscatilin was found to have the strongest activity at the same concentration. The lowest effective concentration of moscatilin was 1 micromol x L(-1). Further results showed that moscatilin inhibited VEGF-induced capillary-like tube formation on HUVECs in a concentration-dependent manner. Western blotting results showed that moscatilin also inhibited VEGF-induced phosphorylation of VEGFR2 (Flk-1/KDR) and extracellular signal-regulated kinase 1/2 (ERK1/2). Further results showed that moscatilin inhibited VEGF-induced activation of c-Raf and MEK1/2, which are both upstream signals of ERK1/2. Taken together, results presented here demonstrated that moscatilin inhibited angiogenesis via blocking the activation of VEGFR2 (Flk-1/KDR) and c-Raf-MEK1/2-ERK1/2 signals.

OBJECTIVETo compare the clinical efficacy difference between encircling needling combined with physical factor therapy and simple physical factor therapy for severe pressure sore, and to explore the optimal method for severe pressure sores.

METHODSThirty-four patients with IV-grade pressure sore were randomly divided into an observation group and a control group, 17 cases in each one. Patients in the control group were treated with conventional nursing, ultrasonic wave and short-wave ultraviolet therapy; additionally, the encircling needling was applied in the observation group. All the treatment was given once a day, 5 times a week, and 4-week treatment constituted one session. Totally, two sessions of treatment were performed. Three indices, including the area of pressure sore, 24-h volume of exudates and wound-bed tissue type, were compared between the two groups before and after treatment; the clinical efficacy was evaluated in the two groups.

RESULTSAfter treatment of one session and two sessions, the area of pressure sore, 24-h volume of exudates and wound-bed tissue type were significantly reduced in the two groups (P < 0.01, P < 0.05), which was more obvious in the observation group (all P < 0.05). The total effective rate in the observation group was 76.5% (13/17) after 1 session and 94.1% (16/17) after 2 sessions, which were superior to 35.3% (6/17) after 1 session and 64.7% (11/17) after 2 sessions in the control group (both P < 0.05).

CONCLUSIONEncircling needling combined with physical factor therapy can obviously reduce the pressure sore area and 24-h volume of exudates and improve wound-bed tissue type, which is superior to simple physical factor therapy.
