Objective:To investigate the complications of traumatic optic neuropathy and to call the surgeons' attention to precaution. Method:Retrospectively analysis of 122 cases patients with traumatic optic neuropathy and 3 cases were analyzed in detail including 1 case with purulent meningitis, another 1 case with internal carotid artery pseudoaneurysm and the other 1 case with internal carotid artery cavernous sinus fistula. Result:Most of the patients had the complications of orbital fracture, maxillofacial fracture, ocular and craniocerebral injury. A few of patients had other injuries all over the body. The case with purulent meningitis was cured with antibiotics. The case with internal carotid artery pseudoaneurysm was cured with neurosurgery. The visual acuity of the both cases were improved. The case with internal carotid artery cavernous sinus fistula died of severe hemorrhea. Conclusion: The patient with traumatic optic neuropathy has the possibility of severe cranial disorders,orbital fracture, maxillofacial fracture and injuries of viscera or limbs. It should be paid mare attention and treated accordingly.

Objective To evaluate the effects of ischemic time factors on reduction of myocardial ischemia-reperfusion injury by sulfentanil postconditioning in rats .Methods Healthy adult male Sprague-Dawley rats ,weighing 230-250 g ,were heparinized and anesthetized with intraperitoneal 5% chloral hydrate 8 ml/kg .The hearts were excised and perfused in a Langendorff apparatus with K-H solution .After 30 min of stabilization ,48 isolated rat hearts were randomly assigned into 6 groups (n=8 each) using a random number table .In I/R1-3 groups ,the hearts were subjected to 30 ,45 ,and 60 min of myocardial ischemia ,respectively ,followed by 90 min of reperfusion . In SP1-3 groups , the hearts were subjected to 30 , 45 , and 60 min of myocardial ischemia , respectively ,followed by 90 min of reperfusion ,and sulfentanil 100 nmol/L was added to K-H solution at 15 min of reperfusion for postconditioning . Left ventricular end-diastolic pressure (LVEDP ) , left ventricular developed pressure (LVDP) ,+dp/dtmax ,-dp/dtmax ,HR and coronary flow (CF) were measured at the end of equilibration and 15 ,30 ,60 and 90 min of reperfusion .Creatine kinase (CK) and lactate dehydrogenase (LDH) activities in coronary effluent were measured at 5 min of reperfusion .Myocardial infarct size was determined in 5 hearts chosen randomly at 90 min of reperfusion .Results LVEDP was significantly higher ,and LVDP , ± dp/dtmax and CF were lower at each time point of reperfusion than at the end of equilibration in I/R1-3 groups ( P<0.05) .Compared with I/R1 and I/R2 groups ,LVEDP was significantly increased ,and LVDP and ± dp/dtmax were decreased at 30 ,60 and 90 min of reperfusion ,HR and CF were decreased ,and CK and LDH activities in coronary effluent and infarct size were increased at 15 and 30 min of reperfusion in group I/R3 ,and LVEDP was significantly decreased ,LVDP , ± dp/dtmax and CF were increased ,CK and LDH activities in coronary effluent and infarct size were decreased at 30 , 60 and 90 min of reperfusion in groups SP1 and SP2 ( P< 0.05 ) . Compared with group I/R3 , LVDP was significantly decreased at 30 ,60 and 90 min of reperfusion ( P<0.05) ,and no significant change was found in CK and LDH activities in coronary effluent and infarct size in group SP3 ( P>0.05 ) .Conclusion Sulfentanil postconditioning can attenuate myocardial ischemia-reperfusion injury when the rats are subjected to 30 or 45 min of ischemia ,however ,it provides no myocardial protection when the rats are subjected to 60 min of ischemia .

Near-infrared (NIR) was used as rapid analysis method to identify the sulfur fumigated Puerariae Lobatae Radix. NIR spectra of the cross-sectional and longitudinal selection of samples were acquired. Principal component analysis was conducted. The samples were randomly selected. The different pretreatment methods were compared. Discriminant models were established for every type of spectra to calculate the recognition rate. The orthogonal test and nonparametric test were used to test data normality. The result showed that absorbance values of different sections were different due to the different structure, and the raw spectra were analyzed by PCA method. The result founded that the cumulative contribution rate was arrived at 99.2% while the PC numbers were arrived at 3. The pretreatment method based on the MSC + 1D + Savitzky-Golay was the best to establish the model. For the 50 models constructed with cross-section and longitudinal spectra and total spectra, the recognition rate were (94.4 ± 0.66)%, (94.4 ± 0.66)%, (95.3 ± 0.65)%, respectively, and no difference was observed. The NIR method could be used to identify the sulfur fumigated Puerariae Lobatae Radix.

Objective To explore protective effect of topiramate (TPM) and folic acid (FA) on mitochondrial damage in hippocampal CA3 neurons during pentylenetetrazol- induced kindling in immature rats.Methods Pentylenetetrazol (PTZ) - induced kindling in rats was used to establish rat models of epilepsy.Forty-eight 3-week-old male Wistar rats were randomly divided into 4 groups: two therapy groups with TPM 40 mg/(kg?d) or TPM 40 mg/(kg?d) and FA 5 mg/(kg?d) administration, 2 control groups (positive control group and negative control group) with the equal amount of distilled water administration. The seizure behaviors of rats were evaluated. Two months later, the rats were killed and the brain sections were made. The mitochondrial ultrastructures of neurons in hippocampal CA3 region were observed with transmission electron microscope.Results In the positive control group, the frequency of seizure was (48.4 ? 3.7)times, while in TPM group (44.3 ? 3.1)times and in TPM and FA group(40.8 ? 3 .7)times.The differences were significant among three groups (Pa

Objective To investigate the influence of thiamine deficiency(TD)at early pre- pathological lesion stage on cognitive function and the correlation between cognitive dysfunction and hippocampal neurogenesis.Methods TD mouse model was prepared by feeding a thiamine-depleted diet. Learning and memory functions of TD mice were tested with Y-maze.Hippoeampal neurogenesis was studied with bromodeoxyuridine(BrdU),proliferative cell nuclear antigen(PCNA),and Doublecortin(Dcx) immunohistochemical staining on the 7th(TD7),9th,14th and TD25th day.Results TD9 mice without pathological impairment and cholinergic nerve degeneration needed more times of training(22.3?2.2)in the learning test of Y maze compared with the controls(13.5?3.5).Correspondingly,the numbers of BrdU-positive ceils and the immunoreactivity of Dcx decreased significantly in the TD9 mice(19.8?0.4, 1537.2?50.2 vs 23.9?0.3,2688.9?127.9 pixels/mm~2).Thiamine re-administration reversed the declined hippocampal neurogenesis:the number of BrdU-positive cells was 23.6?1.9 and Dcx immunoreactivity was 2052.3?269.6 pixels/mm~2:the impaired learning ability was simultaneously restored,with the number of total training trial being 16.8?0.5.Conclusion The decreased hippocampal neurogenesis contributes to retarded learning ability at early pre-pathological lesion stage of TD.

The effects of exogenous phytohormones on hairy root growth and biosynthesis of anthraquinones in the hairy root cultures of Polygonum multiflorum Thunb. were studied. The results showed that the 2,4-D, NAA and 6-BA all have obvious effects on the growth of hairy root cultures and the biosynthesis of anthraquinones. The growth of hairy root and biosynthesis of anthraquinones were strongly restrained by 2,4-D. However, NAA and 6-BA of appropriate concentration were favourable to hairy root growth and anthraquinones production.

METHODSForty-one patients with previously untreated advanced or recurrent gastric cancer received intravenous infusion of oxaliplatin at the dose of 130 mg/m(2) on day 1 and oral administration of capecitabine at 1000 mg/m(2) twice a day on days 1-14. The chemotherapy was repeated every 2 weeks for a median of 4 cycles.
RESULTSTwo of 41 patients achieved a complete response, and 15 had partial responses, with an overall response rate of 41.5%. Stable disease was observed in 11 patients and progressive disease in 9. The median time to progression and overall survival was 6.2 months and 11.8 months. All the 41 patients were evaluated for toxicity according to NCI criteria, 4 showed grade 3-4 neural toxicity, 4 had hematological toxicity and 3 had hand-foot syndrome.
CONCLUSIONThe XELOX regimen shows good efficacy with an acceptable toxicity profile in advanced or recurrent gastric cancer patient.
