Objective To observe the changes of combined therapy on disci intervertebrales and their surrounding tissues and thus to determine its therapeutic effects on lubar intervertebral disc protrusion with magnafic resonance imaging. Methods After combined therapy including physical agents, drugs, traction, manipulation and remedial exercises had been adopted to treat 40 iubax intervertebral disc protrusion patients for 30 days, morphologic changes of disci intervertebrales and their surrounding tissues of these patients were observed by magnetic resonance imaging. Results The effective rate of combined therapy on lubar intervertebral disc protrusion was 82.5%, there were no obvious changes of thickness, salient degree of disci intervertebrales, anteroposterior diameter, transverse diameter and latero-cryptae extent of vertebral canal after the treatment. Conclusion Though the combined therapy can not change the morphous of lobar intervertebral disc protrusion, it may efficiently relief the clinical symptoms of patients with lobar intervertebral disc protrusion.

Aim To investigate the effects of paeonol on lipopolysaccharide ( LPS) and adenosine 5′-triphos-phate ( ATP) induced NLRP3 inflammasome activation in primary rat microglia and the mechanisms responsi-ble for this anti-inflammatory effects. Methods Pri-mary rat microglia were identified immunohistochemi-cally using the cluster of differentiation 11 b ( CD11 b ) antibody. Proinflammatory cytokine IL-1β was deter-mined by ELISA. Western blot was performed to ob-serve the protein expression of NLRP3 , ASC and caspase-1 in cultured primary rat microglia. The level of intracellular reactive oxygen species ( ROS) was mo-nitored by using the fluorescent probe 2′, 7′-dichlo-rofluorescein diacetate ( DCFH-DA ) . Results LPS (0. 5 mg · L-1 )/ATP ( 5 mmol · L-1 ) significantly increased intracellular ROS level and IL-1β secretion and upregulated NLRP3 , ASC and caspase-1 protein expression in primary rat microglia. Paeonol signifi-cantly decreased intracellular ROS level and IL-1β se-cretion, and inhibited LPS/ATP induced overexpres-sion of NLRP3 , ASC and caspase-1 in cultured primary rat microglia. Conclusion Paeonol can inhibit LPS/ATP induced NLRP3 inflammasome activation in pri-mary rat microglia, and this inhibitory effect may be through the suppression of intracellular ROS.

The main teaching methods for medical students and residents are didactic teaching,rote learning and apprenticeship.Although these teaching methods can be good for imparting knowledge,they are obviously insufficient for the training of technical skills,team cooperation and complex decision making.Application of biomedical engineering simulation in the anesthesia teaching can partially compensate for the insufficiency.The progress of biomedical engineering simulation in anesthesia teaching is reviewed and the educational trend was explored.

Objective To evaluate a new suture coil in endoscopic submucosal dissection (ESD). Methods Data of 15 patients with early gastrointestinal cancer undergoing ESD were retrospectively ana?lyzed. The edge of the lesion was pulled up by the new coil?assisted suture for the submucosal layer to be full?y revealed, then the submucosa were dissected,and the wound was stitched by suture coil. The success rate and complications were evaluated. Results The lesions were successfully resected in 15 patients. By pull?up, the submucosal blood vessels were completely revealed. No intraoperative uncontrollable bleeding oc?curred. Small perforation occurred in one patient, and was well stitched by the suture coil. The pull?ups were successfully completed in all patients, and the operation time was 5?10 min. The intraoperative slippage of fixed titanium clips occurred in two cases. All the wounds were stitched. Minor bleeding happened in 1 pa?tient, and was controlled by hemostatic clip. Conclusion The new suture coil is easy to use,and can effec?tively prevent and deal with the occurrence of intraoperative and postoperative ESD?related complications.

Objective To evaluate the value of minimally invasive technique in treatment of severe traumatic intracranial hematoma at emergency department.Method From January 1995 to December 2005,126 patients were treated by using the minimally invasive technique in Affiliated Chaoyang hospital once patients were diagnosedas severe traumatic cerebral hernia resulted from intracranial hematoma and also those whose clinical data were retrospectively analyzed.In the emergency department,the per-operative plan was done according to the CT imaging,including the sute of burr hole on the skull,the direction and depth of carmulation,and the drainage cannula was put into the hematoma cavity for external drainage under local anesthesia.Results The successful rate of puncture was 100%.The patients's dukated oyouk contracted immediately after drainage.There are 79/ 95 patients(83.1%)had single pupil dilated and 17/31(54.8%)patients had bilateral pupils dilated.The immediately clinical effective was 76.2%.According to Glasgow outcome scale,43 of 126 patients had good recovery,26 had moderate deficits and 18 had severe sequelae,16 patients were in vegetative state,18 died. Conclusions Clinical prospective study proves that minimally invasive technique can ameliorate the cerebral hernia,prolong the operative therapie window time.

Objective To investigate the protective effects of midazolam on noise-induced hearing loss in guinea pigs by testing reactive oxygen species (ROS) level in the cochlea and plasma SOD and MDA. Methods Totally forty male pigmented guinea pigs were randomly divided into four groups: control (C) , midazolam (M), normal saline (S) and noise-induced deafened (D) groups, with ten guinea pigs in each. Groups M, S and D were exposed to a continuous noise (4kHz , octave band, 100dB SPL) 3h every day for 3 consecutive days. Group M was treated with midazolam, which was administered intramuscularly (0.1mg/kg) 24h before noise exposure, and immediately upon and during noise exposure. Group S was exposed to noise and treated with the same volume of normal saline intramuscularly, the time of injection was the same as that of Group M. Group C was not exposed to noise, but was treated with midazolam intramuscularly, the time of injection and the dosage were the same as those of Group M. Group S was exposed to noise and treated with normal saline intramuscularly ,the time of injection was same with that of Group M.Group D was exposed to noise only. All animals received auditory brainstem response (ABR) threshold recording before and immediately after noise exposure. Blood was collected when the guinea pigs were killed after the last ABR threshold recording, and serum SOD activity and MDA content were detected. Both the cochleae were removed and prepared for ROS assay. Results After noise exposure, ABR threshold shift (1.6±1.5) and ROS content [(291.10±2.30)u/mL] in Group M were significantly lower than those in Groups S and D [41.7±3.3, 44.3±3.9; (348.52±3.60)u/mL, (315.56±6.70)u/mL, P<0.05]. Serum SOD activity and MDA content were significantly increased in Group M, but the amplitude was less than that in Groups S and D.Conclusion Midazolam can prevent noise-induced hearing loss by reducing the increased ROS level in the cochlea after noise exposure.

Objective To investigate the photo-protective mechanisms of hydroxychloroquine and epigallocatechin gallate (EGCG) on HaCaT cells damaged from UVB irradiation. Methods Subconfluent HaCaT cells were irradiated with different doses of UVB irradiation and treated with the above listed agents. The mRNA expression levels of p53, p21, c-fos and GADPH genes were evaluated by reverse transcription-polymerase chain reaction (RT-PCR). Results UVB irradiation induced mRNA expression of p53, p21 and c-fos in cultured HaCaT cells, which were alleviated by hydroxychloroquine and EGCG treatment in UVB irradiation group. Conclusions The photo-protective effects of hydroxychloroquine and EGCG on HaCaT cells by UVB irradiation might be related to inhibition of the expression of p53,p21 and c-fos genes.
