Objective To study the relationship between the stenosis content of carotid artery and the degree of homocysteine (Hcy) by analyzing the level changes of Hcy in ischemic stroke patients.Methods One hundred and thirty patients of carotid artery stenosis with ischemic stroke were divided into four groups based on the degrees of carotid artery stenosis determined by ultrasound Doppler flow imaging:the slight stenosis group (32patients),the moderate group (35 patients),the severe group (33 patients) and the total occlusion group (30 patients).Meanwhile,30 healthy people were chosen as the control group.The levels of serum homocysteine (Hcy),total cholesterol (TC),triglyceride (TG) and low density lipoprotein (LDL) of each group were measured,and the results were compared with those of the control group.Results It was found that the serum Hcy level in ischemic stroke group were significantly higher than that in the control group (P＜0.05),whereas the variations ofTC,TG,HDL and LDL levels between the ischemic stroke group and the control group could be neglected (P＞0.05).An obviously increased order of serum Hcy levels was observed as the following,the control group,the slight stenosis group,the moderate group,the severe group as well as the total occlusion group.The difference between every two groups was statistically significant (P＜0.05).The level of serum Hcy was positive correlated to the content of carotid artery stenosis (r=0.835,P＜0.05).However,no correlation was found between the carotid artery stenosis and each level of TC,TG and LDL (r=0.031,0.012,0.018,respectively,P＞0.05).Conclusions The serum Hcy level is closely related to the degree of carotid artery stenosis,and high level Hcy is suggested to be one of major risk factors for ischemic stroke.

AIM: To study the difference in glucose and lactate levels between brain extracellular fluid (ECF) and plasma in rabbits in the different blood glucose levels. METHODS: Using intracerebral microdialysis technology, brain ECF levels of glucose and lactate were measured in every 10 min under basal conditions and during a hyperglycemia-hypoglycemia clamp study. RESULTS: Under basal condition, brain ECF glucose levels were markedly lower than ambient plasma levels (30% of plasma), whereas ECF lactate levels were substantially higher (165% of plasma). During the hyperglycemia-hypoglycemia clamps, the relationship between plasma and ECF levels of glucose remained similar, but changes in ECF glucose lagged about 30 min. There were no substantially changes in ECF levels of lactate during dynamical study. CONCLUSION: There are striking differences in glucose and lactate levels between brain ECF and plasma. Lactate may involve in the metabolic process of central nervous system.

This study aims to establish a new method for quality evaluation of Gentianae Macrophyllae Radix by simultaneous determination of five iridoids (loganic acid, 6'-O-beta-D-glucopyranosylgentiopicroside, swertiamarin, gentiopicroside, sweroside), and to detect five iridoids in the root of eight species (Gentiana macrophylla, G. straminea, G. crassicaulis, G. dahurica, G. robusta, G. waltonii, G. lhassica, and G. tibetica). The separation was carried out on a Shiseido SPOLAR C18 (4.6 mm x 250 mm, 5 microm) column eluted with mobile phase of water containing 0.04% formic acid (A) and acetonitrile (B) in a gradient program. The flow rate was 0.8 mL x min(-1). The detect wavelength was set at 240 nm. The column temperature was kept at 30 degrees C. The volume of injection was 5 microL. The five iridoids were well separated with ideal linear correlations. The average recoveries were 97.35% - 106.23%. All the five iridoids were detected in the root of eight species. The contents of same species changed in a somewhat wider range. The contents in root of G. dahurica were lower than that in other species.

Objective To explore the change of cellular immune function in renal cancer patients adopting thymopetidum (TP-5) combined with cytokine-induced killer cells (CIK) in peroperative period,and evaluate its curative effect.Methods Forty-one cases of Ⅰ-Ⅲ stage renal cancer patients adopting CIK treatment postoperatively were enrolled in this study for retrospective analysis.According to applicating condition of TP-5,the patients were divided into two groups:16 cases of combination group (TP-5+CIK) and 25 cases of CIK group.The patients in combination group were given TP-5 intramscular injection everyday from preoperative 1 d to postoperative 3 weeks,once a day.Peripheral blood mononuclear cell was collected in the patients of two groups,which was cultivated for 2 weeks and then transfused.Fasting peripheral blood 1 week (before collected peripheral blood mononuclear cell),3 weeks (before CIK retransfusion),4 weeks(after CIK retransfusion for 1 week) and 5 weeks(after CIK retransfusion for 2 weeks) after operation were examined,the peripheral blood T cell subgroups (CD3+,CD4+,CD8+) and nature killer cell (NK cell) levels were detected using flow cytometry.Results At 1 week and 3 weeks (before CIK) after operation,the levels of CD3+,CD4+/CD8+ and NK cell in combination group were significantly higher than those in CIK group:1 week after operation:0.542 ± 0.063 vs.0.491 ± 0.054,0.94 ± 0.09 vs.0.90 ± 0.12,0.247 ± 0.025 vs.0.223 ± 0.033;3weeks after operation:0.641 ±0.058 vs.0.587 ±0.062,1.71 ±0.13 vs.1.02 ±0.07,0.319 ±0.038 vs.0.264 ± 0.047).There were significantly differences (P＜ 0.05).At 4 weeks after operation,the levels of CD3+,CD4+/CD8+ and NK cell in combination group were significantly higher than those in CIK group:0.698 ± 0.041vs.0.649 ± 0.050,2.01 ± 0.11 vs.1.64 ± 0.09,0.331 ± 0.029 vs.0.289 ± 0.034.There were significantly differences (P ＜ 0.05).At 5 weeks after operation,the levels of CD3+,CD4+/CD8+ and NK cell in two grotups were no significant difference (P ＞ 0.05).At 4 and 5 weeks after operation,the levels of CD3+,CD4+/CD8+ and NK cell in two groups were significantly higher than those of 3 weeks after operation (P ＜ 0.05).None of patients occurred acratia,hyperpyrexia,shivering and so on.Conclusions The application of TP-5 treatment in peroperative period can promote the recovery of cellular immune function,which has synergistic effect with CIK.The value of TP-5 is worthy of promotion.

Objective To study the auditory perception and speech ability outcomes after cochlear implantation in prelingually deaf children with extremely severe neurosensory hearing loss and comorbid leukoencephalopathy.Methods Our study included 14 prelingually deaf children with leukoencephalopathy (confirmed by preoperative MRI scanning) who were treated with cochlear implantation in the Department of Otorhinolaryngology Head and Neck Surgery of Hainan Provincial People''s Hospital, including 8 males and 6 females of 1~6 yr with a mean age of 3.8 yr.Sixteen synchronous prelingually deaf children without central nervous system (CNS) diseases were also included as the control group, including 11 males and 5 females of 1~6 yr with a mean age of 4.4 yr.All the patients underwent pre-surgical assessments of audiology, radiology, speech ability and intelligence before cochlear implantation via transmastoid facial nerve recess approach was done, after which rehabilitation was provided at the Hainan Rehabilitation Center for Deaf Children.Categories of auditory performance (CAP) and speech intelligibility rate (SIR) were employed as the assessment criteria for the outcome of surgery, the scores of which at different timepoints after surgery were statistically compared through paired t-test between the two groups.Results All the patients gained post-surgical hearing and speech abilities to different degrees, whereas CAP and SIR scores both chronologically improved in the both groups.No statistical difference was revealed either in CAP or in SIR scores between the two groups at 6, 12 and 24 months after surgery (P>0.05).Conclusion Children with extremely severe neurosensory hearing loss can be reated with cochlear implantation even if they have comorbid leukoencephalopathy.The effects of auditory and speech rehabilitation for the same age patients with leukoencephalopathy are similar to those without leukoencephalopathy in 2 years after surgery.
