OBJECTIVE:To study the anti-inflammatory effect of ethanol extract of Polygonum multiflorum METHODS:To observe the oedema severity and vaso-permeability in inflamed animal and the response of animal to pain induced by acetate acid after the ethanol extract of Polygonum multiflorum had been intragastrically given for 3 days RESULTS:The oedema severity and vaso-permeability were obviously decreased by the ethanol extract of Polygonum multiflorum and this effect could last 4 hours At the large dose,analgesic effect was observed CONCLUSION:The ethanol extract of Polygonum multiflorum exhibits intensive anti-inflammation effect and the mechanism may be related to its immuno-depression effect

BACKGROUND:Nano bone putty and bone cement injection are two common methods to strengthen the fixation of pedicle screws, but there are relatively few reports on the comparison of their strengthening effects. OBJECTIVE:To compare the biomechanical characteristics of bone cement and nano bone putty strengthening pedicle screw implantation in the fixation of osteoporotic vertebral body. METHODS: Totaly 24 human cadaveric pedicles were obtained, which were al in line with osteoporosis standards, and randomly divided into 3 groups: control group (only implanted pedicle screws), bone cement group (first injected bone cement in the nail channel, and then implanted pedicle screws) and nano bone putty group (first injected nano bone putty in the nail channel, and then implanted pedicle screws). After 2 hours of implantation, the maximum axial pulout strength and the maximum rotation torque of specimens in each group were determined. RESULTS AND CONCLUSION:The maximum axial pulout strength and maximum rotation torque of the bone cement and the nano bone putty groups were greater than those of the control group (P < 0.05), and the maximum axial pulout strength and the maximum rotation torque of the bone cement group were greater than those of the nano bone putty group (P < 0.05). These results demonstrate that the maximum axial pulout strength and the maximum rotation torque of pedicle screw implantation in the fixation of osteoporotic vertebral body can be effectively improved by injection of bone cement and nano bone putty, and the strengthening effect of bone cement is more obvious. 

Electrophysiological studies have shown that the spinosolitary tract-dorsal column postsynaptic (SST-DCPS) neurons may project to both the dorsal column and solitary tract nuclei. In order to demonstrate the neurons morphologically, fluorescein dyes, PI and Bb, were injected into the dorsal column nuclei and the solitary tract nucleus respectively. A total 282 cells were found to be retrogradely labeled in the spinal dorsal horn in 10 adult rats. Of them, 51 (18%) cells were PI-Bb doubly labeled; 120 (43%) were PI labled alone; and 111 (39%) were Bb singly labled. Most of these double-labled cells were concentrated in laminae III-V. The existence of double projection neurons that project to both the dorsal column and solitary tract nuclei, namely the physiologically identified SST-DCPS neurons, is morphologically confirmed in the present study. These neurons may transmit information to both visceral and somatic sensory nuclei, indicating they may play an important role in the convergence of somato-visceral afferents.

Objective:To explore the effect of infection on autophagy-related proteins,Beclin-1 and LC3,expression in cerebral white matter in newborn rats.Methods: A total of 64 two-day-old Sprague-Dawley(SD) rats were randomly divided into control and experimental groups(n=32 each).At day 2 to 6 after birth,the rats in experimental group were intraperitoneally injected with 0.6 mg/kg of lipopolysaccharide(LPS) once a day to establish a white matter injury induced by infection in neonatal rats while the rats in control group were injected with equal amounts of normal saline.Rats were sacrificed to collect brain tissues at 12 hour,1,3,5 d after model establishment.HE staining was performed to observe the pathological changes.Changes in the expression of Beclin-1 and LC3 in rat white matter were examined by Western blot and RT-PCR.Results: Growth and development of rat in experimental group was slow,cerebral white matter lesions were obvious.Compared with the control group,the experimental group Beclin1 and LC3 protein and mRNA levels in the model after 12 h began to express,1 d reached the peak,and then decreased,each time points were higher than the control group(P<0.05).Conclusion: Early infection in neonatal rats can cause white matter damage;the expression of autophagy-related proteins,Beclin1 and LC3,showed that autophagy may be involved in the pathological process of white matter damage induced by infection.

The tumor metastasis is the major cause of the death of cancer patients.S-100A4 is a member of the S100 family of calcium-binding proteins and has been categorized as a metastasis-associated protein.S-100A4 is a candidate as a molecular marker for metastatic potential with high prognostic significance.An increase in S-100A4 protein expression has been correlated with poor prognosis of patients with breast,colorectal,gallbladder,bladder,esophageal,nonsmall-cell lung,gastric,medulloblastoma,pancreatic and hepatocellular cancers.The overexpression of S-100A4 protein can induce the increase of invasion and mobility of the tumor cells.It has been considered that S-100A4 is secreted by the tumor and stroma cells as a regulator of tumor metastasis.S-100A4 can regulate the progress of cell cycle,change cell adhesion,cell mobility and increase the survival ability of the tumor cells.

Platelet-rich plasma is a volume of autogenous plasma with a high platelet concentration. Platelet-rich gel which is polymerized from platelet-rich plasma becomes a hot topic in the repairing of jaw bones in oral and dentofacial surgery. Presently, the mechanism of platelet-rich gel in enhancement of bone defect repair has not been clarified. Generally, we believed that the unifiation of blood platelet degranulation released many high-concentration growth factor during polymerization stimulated bone formation and accelerated bone repair. In addition, the application of platelet-rich gel has some problems. Thus, wide application of platelet-rich gel in tissue engineering deserves further studies. With the development, platelet-rich gel should be widely used in bone tissue engineering.

Objective To evaluate evidence-based practice of catheter removal strategy in patients with short-term indwelling catheter after partial nephrectomy. Try to apply the best evidence into practice, and further to improvethe quality of clinical nursing through quality review. Methods Two rounds of quality review were carried out in the 2 wards from July to December in 2016. Using the 5 review criteria of best evidence, we reviewed baseline of catheter removal strategies for patients with short-term indwelling catheter after partial nephrectomy and developed appropriate evidence-based practice. Further, the best evidence was integrated into clinical nursing practice, and the prognosis was reviewed after then. Results In the baseline review, the compliance of the 5 review criteria was 0. However, after introducing the best evidence into nursing practice,the compliance was up to 100%. The mastering of evaluation knowledge of catheter removal of nurses increased from 73.00 ± 9.35 to 94.81 ± 3.38 with significant difference (t=12.72, P<0.01). The indwelling time of catheter shorted from (5.69±0.79) d to(4.24±0.82) d. The difference was significant (t=5.47, P<0.01). Conclusions Evidence-based nursing practice improvesthe strategies of short-term catheter removal after partialnephrectomy, while closer cooperation between nurses and doctors are still needed to promote the continuous improvement of nursing quality.
