Objective Increased morbidity of auto-immune disease in senescent individual might be related with the defects of apoptosis after stimulation or induction. Changes of apoptotic features in splenic T lymphocytes were studied in senescent mice. Methods Flow cytometry was used to study the rates of apoptosis by analysing sub-G 1 peak. DNA ladder was observed by agarose gel electrophoresis. Free calcium levels in both cells were detected by Fluo-3 loading. Bcl-2 protein levels were detected by Western blot. Results After co-stimulation with IL-2/ConA, flow cytometry showed that average apoptotic percentage of old T cells was 38.3% ?10.3%,significantly lower than that of young ones (58.6% ? 4.0%, P

ObjectiveTo investigate the clinical features of Chinese dysgraphia and then probe into its mechanisms in a patient with semantic dementia(SD).MethodsThe patient with SD finished the writing part of the Aphasia Battery of Chinese (Aphasia Battery of Chinese,ABC) and the Chinese agraphia battery (Chinese agraphia battery,CAB ) in addition to a series of other neuropsychological tests.Results( 1 ) On the Wechsler Adult intelligence scale,the patient performed poorly on information and vocabulary with scores of 6/29 and 8/80,respectively.He spoke out only 11 names totally on the category fluency test within 1 minute,while 25 names or more than were normal.Semantic features test showed he made 37 right answers of 60 questions,with scores of 8/20 on category,7/20 on function and 8/20 on nature features.(2)The writing disorder exhibited Chinese aphasia agraphia with obvious difficulty in forming characters,wrong characters of the same pronunciation or the same form or unrelated errors,and grammatical impairments.Its damage from serious to light occurred in picture writing( 6/40),writing sentences to convey meaning(1/10),dictation(11/40) and automatic writing(35/40).The transcription was relatively preserved (40/40 ). (3)He scored 20 and 19 points on MMSE and MoCA.Executive function was damaged significantly,while recent memory was preserved relatively.ConclusionThe patient with SD shows an impoverished store of general knowledge and poor comprehension of single-word.The nature of SD's dysgraphia presents Chinese aphasia agraphia,undoubtedly due to progressive deterioration in semantic memory.More importantly,its error types and distribution show apparent discrepancy from that of alphabetic script.Presumably because Chinese writing system is logographic in nature and the pathway of comprehension concerning syllable-orthography-morphemes mapping,while alphabetic writing system follows a principle of mapping graphemes on-to phonemes and letters themselves dont stand for any meaning.

Associating liver partition and portal vein ligation for two-staged hepatectomy(ALPPS) is a novel approach for hepatectomy.The case we reported was a 68 years old male patient diagnosed with hilar cholangiocellular carcinoma and obstructive jaundice.ALPPS surgery was operated.Since the patient's left lateral lobe volume was less than 40％ of the whole liver volume (merely 33.91％),the ligation of the right portal vein,plus in situ split of the junction zone between left medial and left lateral liver lobe and the dissection of portal lymph nodes as the first stage operation was conducted.Abdominal CT on the 8th day after the operation reported an increase on the volume of left lateral lobe by 32％ to 41.5％ of the whole liver volume.On the 12th day after the first stage operation,an extended right trilobate hepatectomy combined with left hepatic duct intra-jejunum drainage was performed as the second operation.The patient completely recovered and was discharged three weeks after the second stage operation.

BACKGROUND:Intervention using known inflammatory transmitters has limitations on relieving secondary spinal cord injury. Interleukin-17 is an important proinflammatory cytokine, and is gradual y paid attention in the pathogenesis of central nervous system diseases.
OBJECTIVE:To investigate the altered rule of interleukin-17 mRNA and protein in a rat model of acute spinal cord injury.
METHODS:Healthy male Sprague-Dawley rats were randomly assigned to two groups. In the model group, rats were made into complete spinal cord transaction models. In the sham surgery group, only spinal dura mater was opened, but parenchyma was not injured. Basso, Beattie, Bresnahan locomotor rating scale was used to observe the effects of acute spinal cord injury on limb motor function of rats. Hematoxylin-eosin staining was used to observe histopathological changes at various time points after spinal cord injury. Real-time fluorescence quantitative PCR and western blotting were used to detect interleukin-17 mRNA and protein levels in each group at various time points after spinal cord injury.
RESULTS AND CONCLUSION:Basso, Beattie, Bresnahan locomotor rating scale:Basso, Beattie, Bresnahan scores were 20 to 21 in the sham surgery group. Basso, Beattie, Bresnahan scores were 0 at 1 and 2 days after spinal cord injury. At 7 days, Basso, Beattie, Bresnahan scores were 0 to 3 (P<0.05). Hematoxylin-eosin staining results revealed that compared with the sham surgery group, inflammatory cel infiltration, neuronal and glial cel swel ing, and a reduced number of neuronal processes were observed at 6 hours after spinal cord injury. Gray matter and white matter were loose and vacuolated at 12 hours. Gliocyte proliferation and tissue fibrosis were apparent at 7 days. Real-time PCR results demonstrated that interleukin-17 mRNA appeared at 3 hours, and peaked at 6 hours (P<0.01), and then decreased. Interleukin-17 mRNA levels were similar to the sham surgery group at 7 days. Western blotting results revealed that interleukin-17 expression began to increase at 6 hours and peaked at 12 hours (P<0.05), and then reduced, and reached the levels in the sham surgery group at 7 days. Results indicated that tissue injury was most severe at 12 hours, and showed a time consistency with interleukin-17 expression. It is inferred that interleukin-17 is possibly involved in the process of secondary inflammatory reaction of spinal cord.

Objective To analyze the common respiratory tract infection pathogens distribution and their drug resistance in pedi-atric cardiac intensive care unit(CICU),so as to provide reference for clinical rational use of antibiotics.Methods 1 350 cases of sputum specimens from lower respiratory tract infection patients of pediatric CICU in the medical center between January 2011 and December 2012 were cultivated and drug susceptibilities were tested.The results were retrospectively analyzed.Results 490 patho-genic strains were isolated from 1 350 cases of sputum specimens and identified,including Gram negative bacilli 288 strains (58.78%),Gram positive coccus 140 strains(28.57%),fungi 62 strains(12.65%,mainly Candida albicans ).Gram negative bacilli was given priority to with Klebsiella pneumoniae (62 strains,12.65%),followed by Branhamella catarhalis ,Pseudomonas aerugi-nosa and Escherichia coli .The rates of extended-spectrum beta-lactamases(ESBLs)-producing strains among Escherichia coli and Klebsiella pneumoniae were 73.33% and 66.13%,respectively.Gram positive coccus was given priority to with Staphylococcus aureus (65 strains,13.27%),followed by Streptococcus pneumoniae .Methicillin-resistant Staphylococcus aureus (MRSA)accounted for 24.62%.Conclusion Staphylococcus aureus ,Streptococcus pneumoniae and Klebsiella pneumoniae are main pathogens of re-spiratory tract infection in pediatric CICU.And there is multiple drug-resistant bacteria infection.Rational applicattion of antibiot-ics according to the test results of isolation and drug susceptibility is an effective way to control the infection of critical children and reduce the emergence of resistant strains.

[Methods] Gerbils model of cerebral ischemia was set up by occlusion of bilateral common carotid arteries. The dynamic expression of glial fibrillary acidic protein (GFAP) were determined by immunohistochemical method in reperfusion for 24 and 48 hours after 15 minutes of cerebral ischemia. [Results] Positive expression of GFAP reached a peak in reperfusion for 24 hours and was decreased by Buyang Huanwu Decoction and Radix Astragali. Positive GFAP expression was attenuated in reperfusion for 48 hours and enhanced by Buyang Huanwu Decoction and Radix Astragali increased the expression. [ Conclusion ] The regulatory effect of Buyang Huanwu Decoction and Radix Astragali on astrocytes may be one of its mechanisms in repairing nervous function after cerebral ischemia.

Objective To investigate the mechanism of expression of interlenkin (IL)-17 in C57 mice′s spinal cord clamp area,and to provide new targets for clinical treatment of spinal cord injury (SCI). Methods Male C57BL/6 mice were randomly divided into three groups. In the spinal cord injury group,mice were made into spinal cord clamp model. In the sham surgery group, the dura was cut without injuring the spinal cord. The IL-17 neutralizing antibody group received IL-17 neutralizing antibody injection through the cadual vein at 1 hour after the spinal cord clamp . Mouse scale for locomotion (BMS)was applied to evaluate the mice's behavior change of hindlimb in 1-7 days,the real time fluorescent quantitative PCR was used to detect the change in the expression of spinal cord injury district TNF-αmRNA each time,HE staining was conducted to detect the morphological changes of spinal cord injury of the sham surgery group,the spinal cord injury group and the IL-17 neutralizing antibody group at the 7th days. Results After spinal cord injury,the mice's BMS score were 9 in the sham surgery group;in the model of spinal cord injury group,the mice's BMS score were 0 on the 1st day,and 2.9 on the 7th day. In the IL-17 neutralizing antibody group,the mice's BMS score were 0 on the 1st day,and 3.5 on the 7th day. The expression of IL-17 mRNA in the injury area peaked at the 3rd hour,which showed statistical difference when compared with sham surgery group (P<0.05),and then decreased. In other times,it had no statistical difference when compared with sham surgery group (P>0.05),and the expression of IL-17 mRNA reduced the lowest levels on the 7th day. The 7th day following spinal cord injury,mice's spinal cord tissue was complete normal in the sham surgery group. In the spinal cord injury group,a large number of mice's nerve cells were necrotic, a lot of cells formed vacuolated. In the IL-17 neutralizing antibody group, part of mice's nuclear neurons were shrinking, cells formed vacuolated, but part of cells remained morphologically complete. Conclusion IL-17 is involved in secondary immune inflammatory process of spinal cord injury, it may be targets for intervention in the treatment of spinal cord injury.

BACKGROUND:At present, there are few reports about the non-human primate models of type 2 diabetes mel itus in domestic and abroad, so it lacks of standardized production methods and evaluation criteria.
OBJECTIVE:To establish a safe and effective type 2 diabetes mel itus model of rhesus monkey and evaluation method.
METHODS:Twelve rhesus monkeys were randomly assigned to experimental group (n=9) and control group (n=3). Rhesus monkeys in the experimental group were fed with high-glucose and high-fat diet for 4 weeks, and intraperitoneal y injected with 30 mg/kg streptozotocin to establish models of type 2 diabetes mel itus. Rhesus monkeys in the control group were fed with an equal volume of physiological saline. At 12 weeks after injection, peripheral blood serum was col ected to measure fasting blood glucose, lipids, insulin, and C-peptide levels. Intravenous glucose tolerance test and C-peptide release test were used to detect pancreatic gland and pancreatic islet function. Histopathological examination was performed in pancreas, kidney and liver.
RESULTS AND CONCLUSION:(1) 12 weeks after injection, fasting blood glucose, triglycerides, and total cholesterol levels were significantly higher in the experimental group than in the control group (P<0.05). Insulin and C-peptide levels were significantly lower in the experimental group than in the control group (P<0.05). (2) The area under the curve for intravenous glucose tolerance test was increased in the experimental group than in the control group (P<0.05). The area under the curve for C-peptide response test was significantly reduced in the experimental group than in the control group (P<0.05). (3) The pathological sections of pancreas, kidney and liver showed typical pathological changes of diabetes in the experimental group. (4) It is confirmed that we got high achievement about rhesus monkey models of type 2 diabetes mel itus made by high-glucose and high-fat diet combined with low-dose streptozotocin. It is a feasible, safe and effective method.

A novel disposable three electrodes blood alcohol biosensor strip was fabricated by a screen printing technique. Multi-wall carbon nanotube(MWCNT), Meldola′s(MB), alcohol dehydrogenase(ADH)and nicotinamide adenine dinucleotide cofactor (NAD+) were modified on the surface of the carbon working electrode. Then hydrophilic membrane was stuck in the outermost of the three electrodes to make a reaction camera of 5 μL. Experimental results indicated that the biosensor possessed good accuracy and stability, the linear response range was 0.5-20 mmol/L with correlation coefficient of 0.9949, detection limit was 0.22 mmol/L, and the response time was less than 15 s. Some influencing factors to the biosensor were investigated, such as the pH, temperature and interferences. Correlation analysis showed that there was a significant correlation between the methods of biosensor and the headspace vapor phase chromatography in 10 whole blood samples(r=0.97583). Small volume whole blood sucked using siphonage to detect blood alcohol directly and quantitatively was the obvious character of the biosensor.
