Acute pancreatitis is a common serious disease, and considered to be inflammatory disturbance course. The early storm of proinflammatory cytokine releasing evokes systemic inflammatorome response syndrome (SIRS) ,and leads to multiple organ dysfunction syndrome(MOPS). At the late phase, because massive of antiin-flammatory cytokines initiate compensatory anti-inflammatory response syndrome ( CARS), the body immune func-tions suffer suppressed and result in infection or toxemia. So reestablishing baulance of SIRS/CARS has considera-ble clinical meaning to the AP patient morbidity. In this article, we will overview the relevant factors and mecha-nisms of the SIRS/CARS induced by AP.

Objective To explore the related factors with different degrees of pelvic adhesion in pregnancy women by laparoscopy. Methods One huandred and sixty infertile patients who were found with pelvic adhesion by laparoscopy were treated. They were divided into three groups according to the sverity of pelvic adhesion as following :102 with mild adhesion, 44 with moderate adhesion and 14 with severe adhesion . There were 124 pregnancy patients without pelvic adhesion in the control group. Results (1) There was much higher percentage of patients who had surgery history in each of the pelvic adhesion groups than that in the control group (46.1 %, 56.8%, 57.1%,13.7%,P0.05). (4)The rate of endometriosis in adhesion group, mild adhesion and moderate adhesion group significantly was higher than that in control group(13.7%, 12.82%, 15.9%, P

Both aspirin and angiotensin converting enzyme(ACE)inhi bi tors are often used concomitantly in patients with cardiovascular disease.The s afety of the combination has been questioned. The potential antagonistic interac tions between ACE inhibitors and aspirin has become the focus of both increasing research and intense debate,with conflicting conclusions havin g been reported in the literature.We reviewed systematically available literatu re on the interactions between ACE inhibitors and aspirin in hyper- tension,acute myocardial infarction and congestive heart failure and found that further trials are needed to shed light on the effects and mechanism of interaction between these drugs.

Objective To investigate the way of resection of high-sacrum tumors and the reconstruction way of the sacrum. Methods From October 2001 to October 2005,7 patients with high-sacrum tumors were enrolled. After resection, the pelviclring were recormtmcted with Chinese Great Wall pedicle screw system and fibulae graft,corresponding chemotherapy and radiotherapy were given after operation. Results The short-term results were satisfactory with the lumbosacral pain reduced and the neurological function improved in different degrees, however dysuria occurred in 1 ease and 1 case cerebrospinal fluid leakageand 1 case postoperative infection and delayedunion among the 7 eases in this group. In the follow-up period of 6 months to 3 years,4 eases died for tumor recurred or metastasis. Conclusions Surgical procedure,reconstruction of the sacrum and postoperative comprehensive treatment have important effects on the prognosis. Meanwhile,it is operative key to lessen operative hemorrhage,reserve the function of caudal equine and rebuild weight high post function of the pelvis after superior sacrum tumor is removed.

BACKGROUND: Caspase-3 exists in normal cell in form of zymogen and is capable of stimulating cell apoptosis after activated by apoptosis inducing factors.OBJECTIVE: To observe the activity of caspase-3 in hippocampal cytosolic S-100 and neuronal apoptosis in hippocampal regions, so as to discuss the relationship between hippocampal neuronal apoptosis and caspase3 activity during the whole brain ishcemic-reperfuasional injury.DESIGN: Randomized controlled experiment.SETTING: Emergency Department of Southwest Hospital Affiliated to the Third Military Medical University of Chinese PLA.MATERIALS: This experiment was carried out at Southwest Hospital Affiliated to the Third Military Medical University of Chinese PLA from January to April 1999. Totally 182 male Wistar rats were randomly divided into 3 groups: namely sham operation group of 14 rats, cerebral IR group of 84, rats acetyl-asp-glu-val-asp-aldehyde (AC-DEVD-CHO) treatment group of 84 rats, rats in the latter two groups were then subdivided into IR 8, 24, 48, 72, 120 and 168 hours time points subgroups with 14 rats in each.METHODS: The whole brain ischemia 20 minutes and reperfusional model was established on rats in brain IR group and Ac-DEVD-CHO treatment group, and rats were executed separately at post-reperfusional 8, 24,48, 72, 120 and 168 hours for obtaining hippocampal specimen; rats in sham operation group were only underwent anesthesia and operation without common carotid arterial occlusion and burns of vertebral artery, they were executed at 72 hours after operation and hippocampal specimen was obtained. The quantity of amino-methylcoumarin that was produced from the same mass of specimen within same decomposition time was used to reflect the activity of caspase-3. Brain slices that were obtained from different time points were stained and embedded for observing the hippocampal cell apoptosis under fluorescence microscope at 330-350 nm.MAIN OUTCOME MEASURS: ① The caspase-3 activity in hippocampal S-100 in different post-IR time point groups. ② The hippocampal cell apoptosis in different post-IR time point groups. ③ relationship between caspase-3 activity and neuronal apoptosis in hippocampal regions.RESULTS: Totally 182 rats were enrolled in this experiment, 14 rats got lost, thereby date of 168 rats was entered the result analysis. ① The changes of caspase-3 activity in hippocampal S-100 in different post-IR time point groups: There was no change in sham operation group at postoperative 72 hours. In contrast with cerebral IR group, there were obvious reduction in Ac-DEVD-CHO treatment group at post-reperfusional 24, 48,72, 120 and 168 hours [(1.71±0.03, 1.22±0.03; 2.77±0.09, 1.59±0.7;5.54±0.51, 2.3±0.19, 6.28±1.71, 3.43±0.46; 3.11±1.21, 1.73±0.14) nkat/kg;P ＜ 0.05 or 0.01]. ② The hippocampal cell apoptosis in different post-IR time point groups: Under 400× field of vision, the number of apoptotic cells in sham operation group was 1.2±0.4 cells at postoperative 72 hours.It was lower in Ac-DEVD-CHO treatment group at post-reperfusional 24,48, 72, 120 and 168 hours than cerebral IR group [(6.4±1.7, 2.8±0.8;11.8±1.3, 5.8±1.9; 19.8±3.1, 10.0±1.9; 31.2±5.9, 16.4±2.4; 19.8±2.3, 9.0±2.3)cells/400× field of vision; P ＜ 0.01]. ③ Relationship between caspase-3activity and neuronal apoptosis in hippocampal regions: It was proved of linear correlation in cerebral IR group and Ac-DEVD-CHO treatment group,displaying significantly positive correlation r= 0.935 6 or 0.980 0, P ＜ 0.01).CONCLUSION: Caspase-3 activation is one of the major inducer for hippocampal neuronal apoptosis, playing important role in hippocampus neuronal apoptosis in rats during IR injury.

Objective To investigate the roles of Caspase 3 in neuron apoptosis following cerebral ischemia/reperfusion in the rat hippocampus. Methods A model of rats with global ischemia induced by occlusion of the four vessels according to the method by Pulsinelli et al was used in this study. A total of 182 Wistar rats [(220?20) g] were divided randomly into three groups: control group ( n =14), cerebral ischemia group ( n =84), and cerebral ischemia group treated with acetyl asp glu val asp aldehyde (Ac DEVD CHO, n =84). Time points for observation included 8, 24, 48, 72, 120, and 168 h in the latter two groups. Caspase 3 activity in cytosolic extracts (S 100) of hippocampus and apoptotic neurons in hippocampus following cerebral ischemia/reperfusion were observed at the above mentioned time points, respectively. Results (1) No caspase 3 activity was detected in S 100 from the control group. In S 100 from the ischemia group, weak caspase 3 activity was detected at 8 h, but it increased gradually and peaked at 120 h, and then decreased apparently at 168 h after reperfusion. After treatment with Ac DEVD CHO following cerebral ischemia/ reperfusion, caspase 3 activity was inhibited to some extent at each time point. (2) Apoptotic cells were occasionally observed in hippocampus in the control group, but the apoptotic cells increased apparently at 24 h, peaked at 120 h, and decreased a few at 168 h after reperfusion in ischemia group. After treatment with Ac DEVD CHO following cerebral ischemia/reperfusion, apoptosis decreased to some extent at each time point (except 8 h following cerebral ischemia/ reperfusion). (3) Caspase 3 activity in S 100 from hippocampus was positively correlated with apoptotic neurons in hippocampus following cerebral ischemia/reperfusion at each time point ( r =0.9356 in ischemia group, r =0.980 0 in treatment group). Conclusion Caspase 3 may be one of the key causes resulting in neuron apoptosis in rat hippocampus after cerebral ischemia/reperfusion. It may play an important role in ischemia reperfusion brain injury.

Objective To investigate the relationship between transfusion transmitted virus (TTV)infection and neonatal hyperbilirubinemia,the effect of TTV infection on the liver function, and analyse the feature of nucleotide sequences in TTV ORF1.Methods Serum TTV DNA,which were from 58 neonates with high direct bilirubin(DB,including 5 with hepatitis Syndrome),92 ones with high indirect bilirubin(IB),and 85 normal ones,was detected using a nested polymerase chain reaction technique(nPCR),electropherosis and sequence analyse,and serum alanine amniotransferase (ALT)was determined in all neonates.Results In DB neonates,TTV DNA were detected in 7 neo- nates(12.1%,including 3 neonates with hepatitis syndrome);in IB and normal ones,1 neonate had positive TTV DNA(1.1% and 1.25),respectively.Even if there were point mutations in Guangdong's TTV,the homology of Guangdong's TTV(GD1-9)and Japanese TTV(N22)ranged from 87.1%～97.8% at nucleotide level.Conclusion TTV infection may be one of important pathogenesis resulting in neonatal hyperbilirubinemia and liver damage in such patients.Guangdong's and Japanese TTV isolates had the same genotype,some gene mutations maybe increase the pathogenicity in TTV.

Objective To gain purified platelets for further research of the immune function of platelet.Methods Platelets were purified by positive(MS) and negative(LD) magnetic cell sorting(MACS) separation.The percentage of activated platelets was detected by flow cytometry and nucleated cell clearance was evaluated by white cell count.Results The percentage of activated platelets before separation was(2.39?1.10)%,and increased to(2.56?1.08)% and(16.76?4.04)%,respectively,after MS and LD MACS.The clearances of nucleated cells after MACS MS and LD were(98.44?0.24)% and(98.47?0.18)%,respectively.The recovery rate of purified platelet after MS and LD was(76.50?1.49)% and(79.20?2.61)%.Conclusion MACS LD method was more suitable for the platelet purification.
