AlM:To evaluate the value of color Doppler ultrasound in the diagnosis of traumatic retinal detachment.
METHODS: All 50 cases ( 56 eyes ) of suspicious traumatic retinal detachment from January to June in 2013 were enrolled in this study. All first received the two-dimensional ultrasound, then the color Doppler ultrasound, finally, these results were compared with the results of surgery.
RESULTS: All 56 eyes were observed intravitreal abnormal spots by the two-dimensional ultrasound, and 39 eyes were observed color blood signal by the color Doppler ultrasound. Forty eyes were approved retinal detachment by surgery.
CONCLUSlON: lt is better to display the intravitreal abnormal spots and color blood signal by the color Doppler ultrasound than by the two - dimensional ultrasound, so there is important clinical significance of the color Doppler ultrasound in the diagnosis of traumatic retinal detachment.

Objective To study the influence of dietary test designed by Nutritional Department of Henan Provincial People's Hospital on diabetic inpatients' dietary cognition. Methods A total of 134 diabetic inpatients were selected and tested with standard diabetic meaL Self-reporting of oil, salt, staple food, vegetables and meat intake was evaluated. Nonparametric tests were used for statistical analysis. Results There were significant differences in self-reporting of oil,salt,staple food and meat intake between pre and post test (Z= -4.642, -8.700, -2.218, -5. 528,all P<0.05) ; however,no significant change of self reporting vegetable intake was found ( Z = - 1. 385, P > 0. 05 ). Conclusion Dietary test can significantly change patients' cognition about their daily dietary intake.

Aim To study the interfering effects of picroside Ⅱ on the expressions of nuclear transcription factor kappaB(NF-?B)and inhibitor of NF-?B(I-?B) after cerebral ischemic reperfusion in rats. Methods Intraluminal thread methods were applied to establish the middle cerebral artery occlusion reperfusion models in rats. PicrosideⅡ(10 mg?kg-1) and salvianic acid A sodium(10 mg?kg-1 ) were injected from the tail vein for treatment. TUNEL positive cells were counted by immunofluorescence assay. The expressions of NF-?B and I-?B were determined by immunohistochemical assay,and the concentration of NF-?B and I-?B in brain tissue was determined by ELISA. Results The exprssions of NF-?B and I-?B were weakly and the apoptotic cells were scattering at cortex,striatum and hip-pocampus in the sham operative group. In the negative control group,the number of TUNEL positive cells and the expressions of NF-?B and I-?B increased,the absorption(A) values and the concentration were significantly higher than those in the sham operative group(P0.05 ). Conclusion Picroside Ⅱ might downregulate the expressions of NF-?B and I-?B to inhibit neuronal apoptosis induced by inflammation after cerebral ischemia reperfusion injury in rats.

Aim To explore the effect of picrodideⅡ on the expressions of Caspase-3 and poly ADP-ribose polymerase (PARP) in brain tissue following cerebral ischemic reperfusion injury in rats.Methods The middle cerebral artery occlusion reperfusion models were established with intraluminal thread methods in rats. PicrodideⅡ (10 mg·kg~(-1)) and salvianic acid A sodium (10 mg·kg~(-1)) were injected from tail vein for treatment. The neurological function was evaluated with Bederson's test and the cerebral infarction volume was observed with tetrazolium chloride (TTC) staining.The brain structure was observed by hematoxylin-eosin (HE) staining and the apoptosis was counted by TUNEL immunofluorescence assay. The expressions of Caspase-3 and PARP were detected with immunohistochemical and enzyme linked immunosorbent assay.Results After ischemia 2 h and reperfusion 22 h, the rats showed neurological function deficit and cerebral infarction in ischemic hemisphere. The expressions of Caspase-3 and PARP and the number of apoptotic cells in brain tissue increased compared with those in the sham operative group (P <0.05). In picroside and salvianic acid A sodium groups, the Bederson's scores and cerebral infarction volume, the expressions of Caspase-3 and PARP and the number of apoptosis cells were lower than those in the negative control group (P <0.05). While there was no significant difference in five indexes metioned above between picroside group and salvianic acid A sodium group (P >0.05).Conclusion PicrosideⅡ might reduce the expressions of Caspase-3 and PARP to inhibit the neuronal apoptosis induced by cerebral ischemia reperfusion injury and improve the neurological function of rats.

Aim To study the interfering effects of picrosideⅡ on the expressions of nuclear transcription factor kappaB(NF-κB)and inhibitor of NF-κB(I-κB)after cerebral ischemic reperfusion in rats.Methods Intraluminal thread methods were applied to establish the middle cerebral artery occlusion reperfusion models in rats.PicrosideⅡ(10 mg·kg~(-1))and salvianic acid A sodium(10 mg·kg~(-1))were injected from the tail vein for treatment.TUNEL positive cells were counted by immunofluorescence assay.The expressions of NF-κB and I-κB were determined by immunohistochemical assay,and the concentration of NF-κB and I-κB in brain tissue was determined by ELISA.Results The exprssions of NF-κB and I-κB were weakly and the apoptotic cells were scattering at cortex,striatum and hippocampus in the sham operative group.In the negative control group,the number of TUNEL positive cells and the expressions of NF-κB and I-κB increased,the absorption(A)values and the concentration were significantly higher than those in the sham operative group(P<0.05).While in the positive control and picroside groups,the expressions(A values)and concentration of NF-κB and I-κB and the number of TUNEL positive cells were significantly lower than those in the negative control group(P<0.05).There was no significant difference between the positive control group and picroside group(P>0.05).Conclusion Picroside Ⅱ might downregulate the expressions of NF-κB and I-κB to inhibit neuronal apoptosis induced by inflammation after cerebral ischemia reperfusion injury in rats.

Objective To evaluate regenerative nerve and functional recovery of target muscle in rats with sciatic nerve defect bridged by acellular nerve allograft made through chemical extraction.Methods Sciatic nerve of SD rats was processed in a volume fraction of 3％ Triton X-lO0 solution and 40 g/L sodium deoxycholate solution.Morphology of myelin sheath,axons and basal lamina tubes of sciatic nerve segments was observed under the light microscopy before and after the chemical processing.Twenty-five Wistar rats were divided into acellular nerve allograft group (n =10),autograft group (n =10) and normal control group(n =5) according to the random number table.A 1 cm sciatic nerve defect was created in acellular nerve allograft group and autograft group,and was respectively bridged by acellular nerve allograft and autograft.Sciatic nerve function index (SFI) was measured every two weeks.Twelve weeks after surgery,nerve conduction velocity (NCV),recovery rate of compound muscle action potential (CMAP) and recovery rate of muscle force were measured in each group.Results Cellular components including myelin sheath and axons were removed thoroughly,but the basal lamina tubes were preserved completely.At postoperative 2,4,6,8,10 and 12 weeks,SFI in normal control group (-1.7±5.9,-0.3 ±2.5,0.8 ±4.1,-1.4±3.6,-2.5 ±5.7 and-2.1±3.2) was superior over autograft group (-94.3±3.7,-90.1±4.1,-63.7±7.8,-51.9±8.2,-48.8±8.6 and -44.3 ± 10.5) and acellular nerve allograft group (-97.1 ± 5.3,-91.2 ± 6.1,-70.6 ± 5.5,-60.4±6.2,-58.2 ±10.2 and-56.4 ±8.0) (P ＜0.01).At postoperative 6,8,10 and 12 weeks,SFI in autograft group were better than those in acellular nerve allograft group (P ＜0.05).NCV [(61.6 ± 8.1) m/s],recovery rate of CMAP[(98.7 ± 5.9) ％] and recovery rate of muscle force [(101.8 ± 6.6) ％] in normal control group were higher than those in acellular nerve allograft group [(22.3 ± 4.7) m/s,(40.3 ± 9.2) ％ and (43.8 ± 9.3) ％] and those in autograft group [(29.0 ±5.5) m/s,(52.5 ± 10.6) ％ and (54.3 ± 10.5) ％] (P ＜ 0.01).NCV,recovery rate of CMAP and recovery rate of muscle force in autograft group were better than those in acellular nerve allograft group (P ＜ 0.05).Conclusions Acellular nerve segments are harvested satisfactorily by chemical extraction.Sciatic nerve defect in rats can be cured with the acellular nerve allograft,but the repair effect of autograft is relatively better.
