Objective To explore the underlying mechanisms of scalp electroacupuncture (SEA) in treating cerebral ischemia. Methods A total of 70 healthy male Sprague-Dawley rats were randomized into a sham operated group, a model group and a scalp electroacupuncture (SEA) group. Cerebral ischemia was induced in rats by middle cerebral artery occlusion (MCAO). Rats in SEA group were treated with scalp electroacupuncture immediately after the establishment of the cerebral ischemia model by inserting the needles along anterior oblique line of vertex-temporal and posterior oblique line of vertex-temporal, connecting to the Han's Electro-Acupuncture Apparatus. The rats in sham operated group underwent the same operation as that in SEA group but without occlusion. Neurological severity score (NSS) was obtained to evaluate the neurofunctional defect, hemetoxylin and eosin (HE) staining was used to observe the inflammatory infiltration in cerebral tissue, and enzyme-linked immunosorbent assay(ELISA) to measure the contents of IL-1 beta and IL-10 at various time points. Results SEA group demonstrated significant decline in NSS at 72 h after the operation when compared with that of model group (P < 0. 01 ). An apparent attenuation in in-flammatory infiltration was seen in SEA group comparing with that of model group, especially at 48 h and 72 h after operation (P <0.01 ). Apparent decrease in IL-lbeta in SEA group was observed when comparing with the model group at 72 h (P <0.01 ). Statistically significant increase in IL-10 content was seen in SEA group at 48 h and 72 h after operation comparing with that of model group. Conclusions Scalp electroacupuncture might exert brain pro-tection by suppressing leukocytes infiltration via up-regulation of IL-10 and down-regulation of IL-1 beta expression.

OBJECTIVE: To explore the mechanism of scalp acupuncture (SA) in treating cerebral ischemia. METHODS: Sixty SD rats with middle cerebral artery occlusion (MCAO) were randomized into untreated group and SA-treated group, with another group of 10 SD rats without artery occlusion as sham-operated control. Neurological severity score (NSS), hemetoxylin and eosin (HE) staining and enzyme-linked immunosorbent assay were applied to observing the changes of neurofunctional defect, inflammatory infiltration in cerebral tissue and content of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta) and IL-10 at 24, 48 and 72 h after ischemia-reperfusion. RESULTS: There existed significant difference in NSS between SA-treated group and untreated group (P<0.01), especially at 72 h after ischemia-reperfusion. The HE staining results of ischemic cerebral tissue showed an apparent reduction of inflamed lesions in SA-treated group as compared with the untreated group (P<0.01), especially at 72 h after ischemia-reperfusion. The content of TNF-alpha and IL-1beta at each phase point after ischemia-reperfusion in SA-treated was decreased as compared with that in the untreated group, and there were differences between SA-treated group and untreated group at 72 h after ischemia-reperfusion (P<0.01). An apparent increase was observed in IL-10 between SA-treated group and untreated group at each phase point after ischemia-reperfusion, and there were significant differences between SA-treated group and untreated group at 48 and 72 h after ischemia-reperfusion (P<0.05, P<0.01). CONCLUSION: Scalp acupuncture can improve neurofunctional rehabilitation, suppress leukocyte infiltration, decrease the content of TNF-alpha and IL-1beta within a certain range and enhance IL-10 expression so as to suppress cytokines-mediated inflammatory reaction and attenuate cerebral ischemia-reperfusion injury.

Objective To explore the relationship between plasma homocysteine levels and diabetic peripheral neuropathy (DPNP). Methods A crossectional analysis was conducted on 227 patients with type 2 diabetes. Peripheral neuropathy was confirmed using electromyography (EMG). The risk factors possibly associated with diabetic neuropathy or plasma homocysteine levels were analyzed in relation to likelihood of occurrence of DPNP. Results Eighty patients with neuropathy and 147 patients without neuropathy were included. Plasma homocysteine levels were significantly higher in patients with diabetic neuropathy [( 12. 6 ± 3.6 ) μmol/ L] than without diabetic neuropathy [( 8. 2 ± 0. 9 ) μmol/L] ( P <0. 001 ), and the relationship remained significant after adjusting for duration of diabetes, glycosylated hemoglobin A1c (HbA1c), age, renal status, serum folate acid and vitamin B12, and metformin [OR 1.15( 1.02-1.28 ) ,P < 0. 05]. In addition, per increase of 4. 0 μmol/L plasma homocysteine was closely related to the occurrence of neuropathy after controlling for per unit increase of other confounding factors [OR 1.17(0. 94-1.33), P < 0. 05]. Conclusions Hyperhomocysteinemia was an independent risk factor for the occourence of diabetic peripheral neuropathy.

OBJECTIVETo determine a network solution to meet the network requirements of the heavy data flow, load balance, and potential network storms from expansion of picture archiving and communication system (PACS) application.
METHODSIntel Netstructure 480T Giga Switch was used as the main switch and connected to each building by fiber channel at 1 Giga speed to archive 100 MB/s to each port. At the same time, the in-dependence of the original network construction was physically kept. The layer 3 and 4 switchers were used as load balance to reduce the heavy load of the network, and all the cabling for PACS used the super CAT5 along with the Intel NetStructure 1520 to prepare for potential network storms.
RESULTSAn advanced intranet was set up to fully meet the high standard requirement of the PACS. The foundation for upgrading the whole network system to 1 Giga application was built to achieve sharing and transmission of images, information, and patient data within the hospital. The base was established for the standardized management of the hospital.
CONCLUSIONGood planning is the first step in setting up PACS, and the equipment forms the necessary platform to run PACS and all kinds of hospital information system (HIS). The networking construction is the foundation of e-hospital.

Objective To explore the application effects of three-dimensional teaching mode for clinical anesthesiology. Methods 43 students were selected into control group, who were from class one, grade 2010 in the Department of Anesthesiology, Ningxia Medical University. 42 students were selected into observation group, who were from class two, grade 2010 in the Department of Anesthesiology, Ningxia Medical University. The traditional teaching mode were used for the students in control group during the teaching of clinical anesthesiology, while three-dimensional teaching mode were used for the students in observation group during the teaching. At the end of teaching, the teaching results were compared between the control group and the observation group, mainly including the usual scores evaluated from an anaesthesia plan plus an anaesthesia case discussion, and the final scores. The teaching satisfaction questionnaire were used to assess the effects of two teaching methods on the students' interest in learning, the capacity of clin-ical practice, the abilities of exploring, analyzing and solving problems, etc. SPSS 17.0 software was used in statistical analysis. The students' teaching results were tested by using two independent samples t-test. The satisfactions of these teaching effects were tested by using the Chi-square test. Results The usual and final scores in the observation group were significantly higher than those in the control group [(88.1±5.1) vs. (75.3±4.2), (82.1±3.3) vs. (75.7±3.9); P<0.05]. Compared with the control group, the satisfactions of teaching effects in the observation group were higher such as to stimulate interest in learning (60.5% vs. 90.5%), to improve the abilities of self-study (30.2% vs. 83.3%) and clinical practice (51.2% vs. 85.7%), to widen the scope of knowledge (46.5% vs. 88.1%) and to cultivate the spirits of innovation (55.8% vs. 83.3%), etc (P<0.05). Conclusion During the teaching of clinical anesthesiology, the three-dimensional teaching mode has more advantages than the traditional one, which is good for improving the students' innovation and practice abilities.
