Objective To investigate the expression of HSF2 in colonic mucosa of patients with ulcerative colitis (UC),Crohn's disease (CD),intestinal tuberculosis (ITB),intestinal lymphoma (IL),infectious enteritis,Behcet's disease and normal control.Methods Intestinal tissue samples were retrieved from 2003-2011 archived specimen at the Department of Pathology,and assigned to UC group (n =38),CD group (n =29),ITB group (n =31),IL group (n =32),infectious enteritis group (n =32) and Behcet's disease group (n =28).10 cases were recruited as normal control group.The expression of HSF2 in colonic mucosa were detected by immunohistochemistry.Positive cells were counted by Image Analysis.Results The expression rate of HSF2 in intestinal mucosa of UC patients (64.64 ± 15.17) was significantly higher than that of CD (32.44 ± 5.94),ITB (36.93 ± 6.32),IL (36.16 ± 6.55),infectious enteritis (37.86 ±7.76),Behcet's disease (34.90 ±5.92) and normal control (35.54 ±6.76) (P ＜0.05),while there was no significant difference among the latter six groups (P ＞ 0.05).Conclusion HSF2 is closely related with UC,and may play an important role in the pathogenesis,diagnosis and differential diagnosis of UC.

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 To investigate the changes in high voltage-activated (HVA) calcium current in dorsal root ganglion (DRG) neurons isolated from rats with neuropathic pain. Methods Pathogen-free male SD rats aged 4-6 weeks weighing 180-220 g were used in this study. The animals were anesthetized with intraperitoneal pentobarbital sodium 50 mg/kg. Neuropathic pain was induced by ligation of L5 spinal nerve between DRG and sciatic nerve. The nerve was transected distal to the ligature. The animals which showed positive signs of neuropathic pain were decapitated on the 14th postoperative day. L5 and L4 DRGs were isolated and the neurons in the ganglia were enzymatically dissociated (group L5 and L4). The control group received no surgery (group C). The HVA Ca2+ current was recorded using whole-cell patch clamp technique. Results Peak calcium current density was significantly lower in group L5 and L4 than in group C, and was significantly lower in group L5 than in group L4 . Halfactivation value (Va 1/2) was also significantly lower in group L5 than in group C and L4 (P ＜ 0.05). The relative contribution of N-type to the total HVA Ca2+ current was significantly greater in group L5 than in group C and L4(P ＜ 0.05). There was no significant difference in the steady-state inactivation curves among the 3 groups. Conclusion In rats with neuropathic pain, the HVA Ca2+ current in the injured DRG neurons may play a key role in the induction of neuropathic pain.

Objective To evaluate the effect of hydrogen sulfide combined with mild hypothermia on cerebral ischemia-reperfusion (I/R) injury in rats. Methods Eighty male SD rats, aged 3 months, weighing 250-300 g, were randomly divided into 5 groups ( n = 16 each): sham operation group (group S), cerebral I/R group,mild hypothermia group (group M), sodium hydrosulfide group (group NaHS) and NaHS + mild hypothermia group (group NM). In group I/R, M, NaHS and NM, cerebral I/R was induced by occlusion of 4 vessels (cauterization of bilateral vertebral arteries and 15 min occlusion of bilateral common carotid arteries) followed by reperfusion. In group NaHS and NM, intraperitoneal NaHS 14 μmol/kg was injected immediately after reperfusion, while the equal volume of normal saline was injected in the other three groups. At the same time, the rectal temperature was reduced to 32-33 ℃ within 15 min, lasting for 6 h, in group M and NM, while it was maintained at 36-37 ℃by physical method in other groups. Twelve rats of each group were sacrificed after 6 h of reperfusion, and then the hippocampus was removed for determination of the content of H2 S by using spectrophotometer and the expression of p-CREB and BDNF mRNA by using Western blot and RT-PCR respectively. Four rats in each group were sacririced after 72 h of reperfusion and then the hippocampus was removed for microscopic examination. Results The cerebral I/R injury was attenuated in group M, NaHS and NM compared with group I/R, with the slightest injury in group NM. The H2S content was significantly higher in group I/R, M, NaHS and NM than in group S, and in group NaHS and NM than in group I/R and M. The expression of p-CREB and BNDF mRNA was significantly higher in group I/R, M, NaHS and NM than in group S, and in group M, NaHS and NM than in group I/R. The BDNF mRNA expression was significantly higher in group NM than in group M and NaHS. There was no significant difference in the H2S content and the expression of p-CREB and BNDF mRNA between group NaHS and M.Conclusion Hydrogen sulfide combined with mild hypothermia can attenuate cerebral I/R injury by up-regulating the expression of p-CREB and BDNF mRNA in hippocampus in rats.
