BACKGROUND:Although the mechanism why neuronal cels wil die after transient cerebral ischemia has not been completely elucidated, many researches nowadays have investigated the pathological mechanism in the level of celular organs, such as mitochondria.
OBJECTIVE:To summarize and discuss the functions of neuronal mitochondria and apoptosis signaling pathways in transient cerebral ischemia.
METHODS: A computer-based online retrieval was performed to search papers in CNKI and PubMed databases using the key words of “cerebral ischemia, mitochondrion, apoptosis, reactive oxygen species, reperfusion, superoxide dismutase, nitric oxide synthase, Bcl-2 protein family, review” in Chinese and English, respectively. Papers published recently or in the prestigious journals were selected in the same field. After excluding objective-independent papers and repeated studies, 50 papers were included for further analysis.
RESULTS AND CONCLUSION:Recently mitochondria are found to play an important role after transient cerebral ischemia by producing a lot of reactive oxygen species to activate many kinds of signaling pathways and regulate mitochondria-mediated apoptosis. Reactive oxygen cannot only induce biomacromolecule injury but also induce apoptosis signal transduction. Deeply investigation is needed on the pathological mechanism after transient cerebral ischemia.

Objective To retrospectively investigate the characteristics of patients with inflammatory bowel disease (IBD)in last 10 years in Kunming city. Methods Four hundred and thirty consecutive patients with IBD, who had hospitalized in 7 hospitals between January 1998 to March 2007, were investigated. Among them, 379 patinets had ulcerative colitis (UC) and 51 had Crohn's disease (CD). The patients who received coloscopy, histopathological and bariam enema examination accunted for 98.2%, 56.2% and 2.6% in UC group,respectively, and 72.5%,78.4% and 31.4% in CD group,respectively. The gender, age, occupation and the clinical manifestation of the patients, and the results of the colonoscopy and pathological examination were analyzed. Results Most of the UC patients were aged 30 to 39 years and 50 to 59 years with average age of (46.9±15.8) years, whereas CD patients were aged 20 to 29 years with average age of (41.6±17.2)years. The male and urban patients were predominat in both UC and CD groups. Mental workers were common in UC group. The symptoms of diarrhea (302,79.7%), abdominal pain (285,75.2%) and bloody stools (290,76.5%) were major events in UC patients, and those of abdominal pain (44,86.3%), diarrhea (28,54.9%) and weight loss (28,54.9%) were major events in CD patients. The coincidence ratio among colonoseopy, histopathology and bariam enema examinations was 88.4 % ( 329/372 ), 24.4 % ( 52/213 ) and 4/10 in UC patients, respectively, and 86.5%(32/37), 27.5%(11/40) and 75%(12/16) in CD patients, respectively. All of the UC patients were in active stage of disease,including 38.3 % in mild,42.2% in moderate and 19.5% in severe. In CD group, 7.8% was in relief stage and 92.2% in active stage,including 15.7% in mild,43.1% in morderate and 41.2% in severe.Conclusion The understanding of prevalence and clinical characteristics of IBD in last 10 years in Kunming city will be helpful in diagnosis and treatment of the disease.

Objective Research has indicated that hydrogen sulfide(H2S) can regulate the function of N-methyl-D-aspartate re-ceptors(NMDARs) in the brain, but its effect on brain resuscitation requires further investigation.The study was to speculate the effect of H2 S on brain resuscitation as well as the underlying mechanism of neuroresuscitation by investigating the effects of hydrogen sulfide and hypo-thermia on the expression of NR2A, NR2B and phospho-cAMP response element binding protein (p-CREB) of NMDARs in the hippocampus after global cerebral ischemia following by reperfusion. Methods 100 male SD rats were randomly divided into five groups(n=20):sham operation group, model group, mild hypothermia group, NaHS group, NaHS combined mild hypothermia group.Pulsinelli-Brierley four-ves-sel occlusion method was induced to build the injury rat model by reperfusion after global cerebral ischemia .After 15 minutes'ischemia, im-mediate injection of 14μmol/kg NaHS was performed intraperitoneally on NaHS group and NaHS combined mild hypothermia group , while skin cooling(rectal temperature=32-33℃) was done on mild hypothermia group and NaHS combined mild hypothermia group .6 hours late,r hip-pocampus were extracted from rat heads.Respectively, spectrophotometer was applied to measure the content of H2S, Western blot for the expres-sions of NR2 A,NR2 B and pC-REB, and RTP-CR for mRNA level of brain derived neurotrophic (BDNF). HE staining was also performed on brain tissues 72hours after reperfusion on 4 rats from each group to evaluate the pathological changes of pyramidal neurons in CA1 region. R esul ts The content of H 2 S increased in each of the four groups after ischemia-reperfusion compared with sham operation group ( 15.2 ±2.0 nmol/g) (P<0.05).In comparison to model group (25.2 ±3.5 nmol/g), NaHS group (37.5 ±4.0 nmol/g) and NaHS combined mild hypothermia group (38.7 ±4.4nmol/g ) resulted in significant high content of H2S(P<0.05), while mild hypothermia group(26.5 ±3.5nmol/g ) got a mild increase(P>0.05).The gray values of NR2A and NR2B in each group increased compared with sham operation group(P<0.05), re-sulting in NR2A/NR2B<1 in model group and mild hypothermia group while NR2A/NR2B>1 in NaHS group and NaHS combined mild hy-pothermia group.Compared with the expression of p-CREB(0.55 ±0.06) in model group, there were significant increases in mild hypother-mia group(0.99 ±0.15), NaHS group(1.05 ±0.12), NaHS combined mild hypothermia group(1.02 ±0.15)(P<0.05).Compared with the expression of BNDF mRNA(0.83 ±0.12) in model group, there were significant increases in mild hypothermia group (1.11 ±0.13), NaHS group(1.27 ±0.16), NaHS combined mild hypothermia group(1.35 ±0.16)(P<0.05).In comparison to model group, there were signifi-cant alleviation in the injury of pyramidal neurons in hippocampal CA1 region in mild hypothermia group, NaHS group, NaHS combined mild hypothermia group, with the best effect in NaHS combined mild hypothermia group . Conclusion Hydrogen sulfide combined mild hypo-thermia can selectively activate synaptic NMDA receptors and trigger the prosurvival CREB signaling pathway to exert brain resuscitation .

Objective To investigate the effect of hypothyroxinemia on emotion and hippocampus neurons in developing rats.Methods Sixty-nine healthy postnatal day (PD) 1 rats were randomly divided into control group (n =36) and experimental group (n =33).On PD1,experimental group was bilaterally thyroidectomized to establish hypothyroxinemia model,the control group was only given thyroid exposure operation without thyroid resection.On PD10,21,40,serum triiodothyronine (T3),thyroxine (T4),thyrotropicstimulating hormone (TSH) were detected by radioimmunoassay.Tail suspension test,forced swimming test,the elevated-plus maze and open field were respectively employed to detect the anxiety/depression like behavior on PD30,31,32,33.Nisslg staining was used to determine the survival of neurons at PD10,21,40 in hippocampus CA1,CA3,DG regions.Results Serum T4 levels on PD10,21,40 in experimental group decreased significantly as compared with control group (P ＜0.01),while there was no significant difference in serum T3 or TSH level (P ＞ 0.05).In the tail suspension test,immobility time of experimental group [(197.00 ± 19.50) s] was longer than control group [(158.33 ± 32.90) s,P ＜0.05].In the forced swimming test,immobility time of experimental group[(92.11 ± 35.24) s] was longer than control group [(62.00 ± 23.73) s,P ＜ 0.05].In the elevated plus-maze test,total number of arm entries and closed arm entries in experimental group were increased as compared with control group(P ＜ 0.05),percentage of closed arm/total time of experimental group was decreased as compared with control group(P ＜ 0.05).In the open field,there was no obvious difference between the two groups(P ＞ 0.05).On PD10,21,40,the amount of neurons in DG region of experimental group were less than control group(P ＜0.05),while there was no significant difference in CA1 or CA3 on PD10,21,40(P ＞0.05).Contusions Hypothyroxinemia can cause depression,hyperactivity and hippocampus neuron damage of developing rats.
