Malignant bowel obstruction (MBO) is common in patients with bowel or gynaecological canc-er. Although surgery is the primary treatment for most patients with MBO, it should not be undertaken rou-finely in patients with poor prognosis. Nasogastric drainage is only a temporary measure. Serf-expanding me-tallic stents are optimistic in malignant obstruction of the gastric outlet and proximal small bowel.

Gastrointestinal stromal tumours(GISTs)are the most common primary mesenchymal tumours of the gastrointestinal tract and the disease is occasional and asymptomatic. Though the high rate of recur- rence after surgery, operation remains the firstline treatment of the GIST without metabasis. With the consid- eration the molecular biology of tumor, the treatment including surgery and molecular targeted therapy can im- prove the prognosis of GISTs.

Acute kidney injury( AKI) is a variety of causes leading to rapid impaired renal function, causing glomerular filtration rate reduced,blood urea nitrogen elevated,serum creatinine increased,urine out-put decreased,resulting in the disorder of the human body environment,so the body can not maintain homeo-stasis. AKI increases the risk of mortality and chronic kidney disease in neonate. To understand the progress of AKI on diagnostic criteria,pathogenesis,early biomarker,treatment and prognosis,it is extremely important to guide clinical diagnosis and treatment,improve the outcome and reduce the mortality of AKI in neonate.

Objective To study the expression of NM-23 ,PCNA,p53 and S-100 in colorectal cancer tissues and their relationship.Methods Three hundred and seventy eases of elderly eolorectal cancer were labelled with NM-23,PCNA,p53 and S-100 and staged by pTNM classification.Results The positive rates of NM-23,PCNA,p53 and S-100 were 74.9% ,60.3% ,58.1% ,68.1% respectively.In elderly group,the expression of NM-23 had a neg-ative correlation with that of PCNA (r = -0.101 ,P = 0.026).However the expression of NM-23 had a positive corre-lation with that of p53 (r =0.111 ,P =0.016 ),the expression of S-100 had a positive correlation with that of p53 (r=0.112,P = 0.015 ),the expression of S-100 had a positive correlation with that of PCNA (r =-0.229,P =0.000).Conclusions In the elderly patients,NM-23,p53 and S-100 were significantly correlated with the inva-sion,metastasis and prognosis of eoloreetal cancer.PCNA may be a stimulative factor in the invasion and metastasis of colorectal cancer.NM-23 ,PCNA,p53 and S-100 can serve as effective markers in reflecting the invasion,metas-tasis and prognosis of colorectal carcinoma in the elderly.

Objective To evaluate the impact of multiple lacunar infarction (MLI) on the outcomes of mild cognitive impairment (MCI). Methods MCI patients were selected in outpatients and hospitalized patients using a common international standard MCI screen. Magnetic resonance imaging (MRI) and computer tomography (CT) were used to determine the presence of MLI. MCI patients were followed up for 6～24 months and their cognitive status and the impact of MLI on MCI were evaluated using Kaplan-Meier survival analysis. Results One hundred twenty patients were diagnosed as having MCI based on clinical evaluation and neuropsychological assessment. Among them, 43 (35.8%) patients had MLI and the rest 77 (64.1%) patients did not have. Twenty-seven MCI patients with MLI (62.8%) developed dementia, while 15 MCI patients without MLI (19.4%) developed dementia during 6～24 months follow-up. Kaplan-Meier analysis indicated that the incidence of dementia was significantly higher in patients with MLI than in patients without MLI did (P＜0.05). Conclusions MCI patients with MLI are more prone to dementia. These results suggest that early interventions aimed at controlling the modifiable risks are warranted for dementia prevention in MCI patients with MLI.

Objective To establish the quality standard for Haijinhuwei powder. Methods Corydalis Rhizoma, Angelicae Dahuricae Radix, Angelicae Sinensis Radix were identified by TLC. The content of tetrahydropalmatine was determined by HPLC. Results TLC spots were clear and specific.There was a good linear relationship between peak area and concentration of tetrahydropalmatine at the range of 10.78-107.8μg.mL-1(r=0.999 9).The average recovery rate was 96.57% and RSD was 1.40%(n=6). Conclusion All these results indicated that the developed TLC-HPLC method was proved to be reliable, accurate and specific, which could be used for the quality control of Haijinhuwei powder.

Information department in hospitals shoulders the tasks of construction,operation,maintenance and super-vision of hospital information system ( HIS) . The work load increases with the update of HIS. The key issues con-cerned by the chief of HIS include the over planning of resources,optimizing the allocation of techniques,enforcing the means of management, improving the level of service and the efficiency of support. The principles for the design of performance appraisal program and the specific appraisal indicators in Information Department of Chinese PLA Second Artillery Forces were thus described in this paper in an attempt to provide reference for the information management in other hospitals.

Objective To explore if elemene can synergize tamoxifen through using non-cytotoxic dose of elemene and tamoxifen in combination on MCF-7cell line of breast cancer.Methods First,MCF-7 cell line was cultured in RPMI1640.Then,TAM's inhibitory effect united with elemene on MCF-7 cell line was analyzed by using CCK-8 test.Results When adding non-cytotoxic dose of elemene and curative dose of tamoxifen into the two experimental groups,the absorptivity in the two groups reduced notably,compared with that of the groups using tamoxifen alone;accordingly,the inhibition rate in two mixing groups increased obviously compared with that in single-drug groups.Conclusion Elemene of innocuous dose can remarkably enhance the inhibitory effect of tamoxifen,which indicates that elemene may synergize the effect of tamoxifen on breast cancer.

Objective To investigate the influence of Herba Epimedium, a kidney-strengthening Chinese herb, on the regenerate ossification of nano-hydroxyapatite/collagen/ polylactic acid (nHAC/PLA) in the repair of rabbit mandibular defect. Methods Sixteen rabbit models with 10 mm × 8 mm subperiosteal mandibular defect were established. The rabbits were randomly divided into 2 groups, namely Herba Epimedium group and control group. In both groups, the left mandibular defect region (short for left side) was not filled with any material, while the right mandibular defect region ( short for right side) was filled with nHAC/PLA. On week 2, 4, 8, 12 after modeling, rabbits in each group were killed, and then the macro-view, imageology and histology of the bilateral mandibles were observed. The data of the regenerate bone areas were calculated and analyzed with analysis of variance (ANOVA) . Results The imageological results showed bone mineral density in the right side of Herba Epimedium group and the control group, and in the left side of Herba Epimedium group were higher than those in the left side of the control group on week 2, 4, 8, 12 after modeling. The histological results showed that the regenerate ossification in the right side of Herba Epimedium group and the control group was superior to that in the left side of the corresponding groups, with more regenerative bone and vessels. In the right side of Herba Epimedium group and the control group, amount of bone-like tissues were grown into nHAC/PLA, and the maturity degree of bone tissue was increased with the prolongation of time. And the changes were more obvious in the right side of Herba Epimedium group, showing as the remaining of nHAC/PLA having been surrounded and replaced by regenerative bone tissue. Regenerative bone area was increased in both sides of Herba Epimedium group, which differed from the same side of the control group (P<0.05) . The differences of the regenerative bone area were also significant between the left side and right side of the same group (P<0.05) . Conclusion Herba Epimedium can effectively accelerate the repair of mandibular defect, and nHAC/PLA is of good biocompatibility, osteoinduction and bone conduction, and can be expected for bone defect repairing in clinic.

AIM:To investigate the effect and mechanism of liver ischemia/reperfusion(I/R)injury on the changes of cardiac energy metabolism and structure.METHODS:48 healthy Wistar male rats were randomly divided into 6 groups as follows(n=8 in each group):control group(CTL),simply ischemia for 30 min without reperfusion(I group);reperfusion following ischemia for 30 min(I/R group);2 h reperfusion following ischemia for 30 min(I/R 2 h group);4 h reperfusion following ischemia for 30 min(I/R 4 h group)and 6 h reperfusion following ischemia for 30 min(I/R 6 h group).The level of serum endotoxin was measured.The levels of insulin and insulin antibody in heart were detected by radioimmunoassay.The contents of MDA,MPO and lactic acid in heart were also determined.RESULTS:During the process of liver I/R injury,the level of endotoxin increased in I group and I/R group and declined gradually for long time during reperfusion,but was still longer than that in CTL group(P0.05).CONCLUSION:During the process of liver I/R injury,endotoxin is absorbed from intestine and impairment of liver detoxication leads to endotoxemia,which might play a role in the changes of the energy metabolism and structure in heart.
