Objective To study the clinical characteristics,diagnosis and treatment of 8 children with primary ileum cecum malignant lymphoma.Methods Retrospective analysis on the clinical and pathology materials of 8 children with primary ileum cecum malignant lymphoma was performed.Results Primary ileum cecum malignant lymphom′s clinical experience had no characteristic,and radical operation was main treatment method.Chemothereapy got well to some extents.Pathology and immunity tissue chemical were B cell malignant lymphoma.Conclusions Child primary ileum cecum malignant lymphoma lack specific manifestations,and histopathology is main diagnosis methods.They have good response to binding treatment of early operation and chemothereapy.

Objective To study the protective effect of redix astragail on intestinal mucosa barrier in infant rabbits with intestinal ischemiareperfusion.Methods Twenty male infant rabbits were divided into 4 groups randomly:sham control group,intestinal ischemia reperfusion(IIR) group(model group),redix astragail group,control group.Redix astragail group and control group intraperitonerlly injected redix astragail 6 mg/(kg?d)or sodium chloride preoperative.Intestinal mucosa and blood plasma superoxide dismutase(SOD) activity,intestinal mucosa tissue degree of injury were observed in infant rabbits with IIR.Meanwhile,the effect of redix astragail on them was studied.Results After IIR,SOD activity in intestinal mucosa and blood plasma obviously decreased,and intestinal mucosa tissue morphous and intestinal mucosa barrier lesion were progressively aggravated.Redix astragail might increase blood plasma and intestinal tissue SDD activity significantly.Conclusion Redix astragail plays an important role in protecting intestinal mucosa barrier in infant rabbits with IIR.

Objective To explore the pathological basis and clinical characteristics of children with congenital choledochal cyst(CCC) combined with liver damage.Methods According to the age,38 patients with CCC were divided into 2 groups:group A had 24 cases(ranged 6 months to 3 years old);group B had 14 cases(ranged 4 to 14 years old).A comparative analysis of them was conducted retrospectively in the clinical characteristics,hepatic pathological changes,perioperatively liver function and operation.Results Group A was obvious higher than group B in jaundice,white bole stool and abdominal mass,but group B was more in stomachache.Group A was obvious higher than group B in liver function lesion,alkaline phosphatase,bilirubin increase and blood coagulation disfunction(Pa

OBJECTIVE To prevent occurrence of infection in clinical laboratory. METHODS The biosafety system was continuously improved and complet step by step and amplifed rules and regulation,done well protection of person,making the operating process of laboratory more norma,enforcing the air and environment,sterilizeing the equipment,detecting implement,disinfecting the used material and medical garbage and inspecting. RESULTS The hospital infection in laboratory was effectly controlled,the staff′s safety and health were addressd when they worked in an infected area of laboratory. CONCLUSIONS Amplifying the rules and regulation,and insisting the principle of work without slacking could effecttively prevent the occurring of hospital infection in clinical laboratory.

Objective To explore the effects of environmental enrichment (EE) on learning and memory ability and the expression of brain-derived neurotrophic factor (BDNF) and synaptophysin in hippocampus of neonatal rats with hypoxic-ischemic brain damage(HIBD).Methods Forty Wistar neonatal male rats aged 7 days were randomly divided into EE intervention for 6 hours(6 h EE) group (n =10),EE intervention for 12 hours (12 h EE) group (n =10),model group (n =10) and sham group (n =10).The first 3 groups were performed with HIBD.The 6 h EE and 12 h EE group received EE stimuli for 6 h and 12 h respectively,once a day for 14 days.Learning and memory of the rats were tested by using Morris water maze.The expression levels of BDNF and synaptophysin in hippocampus were determined with Western blot.Results The escape latency of all groups gradually reduced with the increase of training days,but there was no significant difference in the escape latency among the 4 groups (F =0.237,P ＞ 0.05).The rats in the 6 h EE group,12 h EE group and model group spent less time in the target quadrant and showed a significant reduction of BDNF and synaptophysin(6 h EE group:0.529 ± 0.038,0.889 ± 0.027;12 h EE group:0.660 ± 0.034,1.114 ± 0.037;model group:0.225 ± 0.015,0.672 ± 0.057) in the hippocampus compared with the sham group (0.803 ± 0.026,1.347 ± 0.092) (all P ＜ 0.01).In the 6 h EE group and 12 h EE group,the rats significantly increased the time spent in target quadrant and aggrandized the expression of BDNF and synaptophysin in hippocampus compared with the model group.Moreover,the 12 h EE group had a better performance than the 6 h EE group in the space exploration and the expression of BDNF and synaptophysin.Conclusion EE is helpful for improving learning and memory ability in neonatal rats with HIBD,which may be associated with up-regulating the expression of BDNF and synaptophysin in hippocampus.

Objective To explore the effect of the exogenous phosphorylation cyclic adenosine monophosphate response element bind-ing protein (pCREB) antibody on the expression of apoptotic regulated genes (Bcl-2 and c-Jun) in hippocampus after status convulsivus (SC), to elucidate the role and regulation mechanism of pCREB in convulsive brain injury. Methods Seizures were induced in 24 adult Wi-star rats with lithium-pilocarpine intraperitoneal injection (SC group), another 24 rats were as the normal controls (NC group). Each group was divided into no injection subgroup, normal saline injection subgroup and anti pCREB subgroup according to the injection contents of lat-eral ventricle, with 8 cases in each group. They were sacrificed 6 hours after injection. Both the protein and mRNA expression of Bcl-2 and c-Jun in bilateral hippocampus were detected by immunohistochemistry and in situ hybridization, respectively. Results There was no signifi-cant difference in Bcl-2 protein/mRNA expression among 3 subgroups in the NC group (P>0.05). In the SC group, the expression of Bcl-2 protein/mRNA were lower in the anti pCREB subgroup than in the no injection subgroup and normal saline injection subgroup (P<0.05). There was significant difference in c-Jun protein/mRNA expression among 3 subgroups in both NC group and SC group (P<0.001). The ex-pression of c-Jun protein/mRNA was higher in the normal saline injection subgroup and the anti pCREB subgroup than in the no injection group (P<0.05), especially in the anti pCREB subgroup (P<0.05). Conclusion Exogenous anti-pCREB antibody can down-regulate the ex-pression of Bcl-2 and up-regulate the expression of c-Jun in hippocampal cells after SC.

A new cadinane-type sesquiterpenoid, pogocablene P (1), and a new natural product with cyclohexanone skeleton, pogocablone A (2), were isolated from the EtOAc soluble fraction of the aerial parts of Pogostemon cablin by several chromatographic methods, such as silica gel, Sephadex LH-20, ODS and high performance liquid chromatography (HPLC), and so on. Their structures were identified by means of mass spectrometry and nuclear magnetic resonance spectroscopy. In addition, the absolute configuration of compound 2 was determined by electronic circular dichroism (ECD) calculation. Furthermore, the anti-influenza virus and anti-inflammatory activities of compounds 1 and 2 were evaluated.
