Shanghai Journal of Acupuncture and Moxibustion 2015;(11):1027-1029,1030
Objective To observe the clinical efficacy of acupuncture in treating acute cerebral infarction coupled with obstructive sleep apnea-hypopnea syndrome (OSAHS).Method Totally 126 patients with acute cerebral infarction coupled with OSAHS were randomized into a treatment group and a control group, 63 cases in each group. The control group was intervened by conventional comprehensive treatment, while the treatment group was additionally intervened by acupuncture treatment. The OSAHS indexes were observed before and after the treatment, and the clinical efficacies were compared between the two groups. Result The OSAHS scores (AHI, minimum SaO2, and ESS score) were significantly changed in both groups after the intervention (P<0.01,P<0.05). The OSAHS scores of the treatment group were significantly different from that of the control group after the intervention (P<0.05). The total effective rate was 93.7% in the treatment group versus 82.5% in the control group, and the difference was statistically significant (P<0.05).Conclusion Acupuncture is an effective approach in treating acute cerebral infarction coupled with OSAHS.

World Science and Technology-Modernization of Traditional Chinese Medicine 2014;(10):2157-2161
This study was aimed to investigate the effect of Yi-Qi Wen-Yang (YQWY) and Huo-Xue Li-Shui (HXLS) decoction on changes of insulin resistance (IR) model and the myocardial tissues of rats with congestive heart failure (CHF) pathology. CHF rat models were established on Wistar male rats through injection of doxorubicin hydrochlo-ride into rat tail vein. Wistar male rats models were randomly divided into the model group, western medicine group, low dose decoction group, middle dose decoction group, and high dose decoction group. After 4-week gavage, 3 mL vein blood was taken from the angular vein sinus for the determination of blood glucose and serum insulin, and the calculation of IR. Finally, the rats were sacrificed. And then, the heart was removed to make HE slice and observe the pathological change of myocardium. The results showed that compared with the model group, YQWY and HXLS decoction can improve the IR level among CHF rats (P<0.05). Among them, the effects of the high dose and middle dose group were obvious. At the same time, this decoction can improve the myocardial cells in CHF rats in myocar-dial cells of the high dose group. And its morphology change was close to the digoxin group. It was concluded that YQWY and HXLS decoction can reverse IR and improve ventricular remodeling among CHF rats to a certain extent.

Objective: To compare the coronal sealing abilities of different post and cement systems through measuring the value of leakage by using dye method. Methods: Fifty human mandibular premolars with single canal were divided into 6 groups randomly. A group: roots sealed by temporary material, B group: roots restored with fiber post adhered with composite resin cement, C group: roots restored with casting metal post and core adhered with composite resin and zinc phosphate cement, D group: positive control, E group: negative control. After finishing preparation and restoration of roots, microleakage was determined by using dye method. Results: The groups restored with any post and core system produced significantly less microleakage than temporary material sealing group(P<0.05). But no differences were detected between two groups bonded with the composite resin cement (P>0.05). Posts adhered with zinc phosphate luting agent produced more leakage than those with composite resin cement(P<0.05). Conclusion: Luting agent can decrease the coronal microleakage. Composite resin cement provides better sealing ability.

Objective To analyze and deploy in the hospital network security for guarantee hospital network and information of safety, and ensure stability operation in the hospital management information system. Methods The network environment was based on the original hospital, which was added to measures about the isolation for network security, the prevention of computer viruses and firewall, data backup and recovery, physical safety management and so on. Results After the comparatively perfect measure of network security was deployed, the security of hospital information and data was effectively protected, and the security threat was solved from the inner and outer network. Conclusion The deployment of network security prevention system can better give fully play to important function on which management information system can efficiently operate in whole hospital.

Objective To evaluate the effects of two different chronic glaucoma models on intraocular pressure elevation and retinal structure changes in rat.Methods Two different chronic ocular hypertension (COH) models were made by three episcleral vein cauterization or latex microspheres injection into anterior chamber,6 cases of each model.IOP measurements of right eyes (COH eye) and left eye (control eye) were taken weekly by TonoPen (an applanation tonometer).Retinal ganglion cells (RGCs) were retrogradely labeled with 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate (DiI) seven weeks later.Retina structure was observed by immunofluorescence.Results IOP was elevated at postoperative 1-8 weeks,and the mean IOP in the episcleral vein cauterization group was (27.20 ± 1.83) mmHg (1 kPa =7.5 mmHg),whereas the control group was (19.80 ± 1.35) mmHg (P =0.001,n =6).The mean IOP in the latex microspheres injection group was (27.40 ± 1.88) mmHg,whereas the control group was (19.40 ± 1.00) mmHg (P =0.000,n =6).Compared with control rat at postoperative 8 weeks,RGCs loss in episcleral vein cauterization group were 37.9%,39.6 and 33.5% (all P =0.000,n =6),latex microspheres injection group were 37.3%,39.4% and 33.5% (all P =0.000,n =6).There was no statistical difference between episcleral vein cauterization group and latex microspheres injection group (P =0.855,0.949,0.634,n =6).Compared with control rat at postoperative 8 weeks,GCL thickness in both COH models were also significant reduced,but there was no statistical difference in GCL thickness among control group (7.32 ± 0.39) μm,episcleral vein cauterization group (4.97 ±0.33) μm,latex microspheres injection group (5.00 ±0.31) μm.Misoperation or careless operation may lead to microspheres particle residual on flat-mounted rat retina.Conclusion The episcleral vein cauterization or latex microspheres injection into anterior chamber can all increase the IOP.However,there are some advantages in episcleral vein cauterization such as few costs than latex microspheres injection and no microsphere contamination.

Four different strains of Leptospira were subcultured in CGM in contrast with in Korthof medium for three years. The antigenic components of these Leptospira grown in the two medium were analysed by the methods of MAT, CIE and SDS-PAGE. The results showed that:1, the antigenic components of Leptospira were very complex and had more than twenty bands stained with Coomassie brilIiant blue in SDS-FAGE pattern; 2. the antigenicity of Leptospira subcultured in CGM for many generations was relative stability and the same as that in Korthof medium.
