The relationship between the behavior of the mononuclear phagocyte system(MPS)and acute pulmonary injury during acute obstructive cholangitis(AOC)was investigated in 90 Wistar rats.After the operation to induce actue obstructive cholangitis,the animals were killed in the Oth,6th,12th,24th and 48th hour,and the phagocytic function of Kupffer's cells,the number of alveolar macrophages in the lung lavage fluid,and the extravascular water content of the lungs were measured.And the pulmonary levels of lipid peroxidase and supperoxide dismutase were determined as well.It was found that when the phagocytic function of Kupffer's cells was suppressed,the alveolar macrophages were activated by the invading bacteria to release some inflammatory mediators such as free radicals resulting in acute pulmonary injury.It seems that there is a close relationship between the fuctional status of mononuclear phagocyte system and the development of pulmonary injury,and the functional failure of mononuclear phagocyte system plays an important role in the pathogenesis of multiple organ failure especially of acute pulmonary injury.

Objective　To investigate the expression of LPS receptor-CD14(CD14) on the membrane of Kupffer′s cells (KCs) induced by Lipopolysaccharide (LPS )and its role in activation of KCs and production of cytokines. Methods　KCs were isolated by collagenase perfused Wistar rats and routinely cultured in 24-well dishes for 12 h. Cells were harvested and adjusted to a concentration of 1×106/ml/well and were devided into two groups. Group of LPS: KCs were induced with different concentration of LPS (0, 100 ng/ml, 1 μg/ml and 100 μg/ml). Group of PI-PLC: KCs were pre-incubated for 30 min with one unit of phophatidy linositol specific phospholipase C (PI-PLC) before different concentrations of LPS were added. KCs were cultured for 30 and 60 min respectively. Supernatants were then collected for measuring the level of TNFα and IL-6. Cells were stained by indirect immunofluorescent method ( rabbit anti-CD14 antibody and goat anti-rabbit IgG conjugated with FITC ) and analyzed with flow cytometer (FCM). The percentage and mean fluorescence intensity (FI) of CD14-positive cells were taken as the indexes. Results　In LPS group, after incubation of cells with increasing concentration of LPS, a significant increase in the percentage of CD14 positive KCs were found and the mean FI was stronger when compared with the control points or the group of PI-PLC. The levels of TNFα and IL-6 in supernatant also increased (P<0.01). In group of PI-PLC, decreased percentage of CD14 positive KCs and weakened mean FI were found when compared with group of LPS. The increasing production of TNFα and IL-6 slowed down in the group of PI-PLC. Conclusion　CD14 expression of KCs might be up-regulated by LPS with increase of some cytokines. The production of cytokines in KCs induced by LPS is partially inhibited by PI-PLC.

Objective To investigate the expression of microRNA -216a(miR -216a)in patients suf-fering with breast cancer ,and identify the function and mechanism of miR -216 a on autophagy .Methods The expression of miR-216 a in 30 tumor tissues and paired normal tissue of breast cancer were detected by qRT -PCR.Inhibiton of miR-216a in MCF-7 cell lines was done by transfection of miR -216a inhibitor ( AMO-216a).Cell viability was detected by MTT assay .The level of Beclin 1 was detected by western blot .Results The level of miR-216 a was significant elevated in tumor tissue .Cell viability was markedly decreased owing to inhibition of miR-216a in MCF-7 cells.The level of Beclin 1 was significantly increased by transfection of miR-216a inhibitor in MCF-7cells(P<0.05).Conclusion The level of miR-216a is increased in breast canc-er tissue, and it might at least in part promote breast cancer via downregulating Beclin 1 and affecting autophagy .

Total 10 450 people received health check-up in our hospital from March 2009 to December 2010.The subjects were classified as high-risk for type 2 diabetes mellitus ( DM ) group ( n =9016) and non-high-risk group (n =1434).The rate of new DM was 3.36％ (303/9016) and the rate of impaired glucose regulation (IGR) was 12.38％ (1117/9016) in high-risk group; while in non-high-risk group there was no new DM cases,and IGR rate was 2.58％ (37/1434).The detection rate of IGR and DM significantly increased with the increasing rate of risk factor and numbers (P ＜ 0.01 ).Logistic regression analysis revealed that the abnormal glucose metabolism was associated with age,male,positive family history,heart rate,hypertension,abnormal lipid metabolism and hyperuricacidemia.The results suggest that subjects with multiple risk factors should be the key population for prevention and screening of type 2 diabetes.

Objective To evaluate the clinical efficacy and safety of two kinds of uterine artery perfusion chemotherapy plus embolization (UACE) in treating ectopic pregnancy (EP). Methods A single center, randomized, double-blind, controlled clinical trial was carried out at authors hospital. A total of 50 cases of EP patients were randomly and equally divided into the study group (perfusion chemotherapy of MTX and 5-FU plus embolization therapy) and the control group (perfusion chemotherapy of pure MTX plus embolization therapy). After UACE, the serumβ-HCG value, the clinical healing time and the tubal patency rate were determined at different time, and the adverse events were recorded. The results were statistically analyzed by using t test, and χ2 test, and the data were compared between the two groups. Results One patient in both groups was excluded from the study. In the remaining 48 patients, one patient of the control group failed to respond the treatment, so the overall cure rate was 97.9%. The differences in the main effect of treatment method and the time interaction of the serum β-HCG values between the two groups were not statistically significant (P > 0.05), while the difference in the time effect between the two groups was statistically significant (P < 0.05). The clinical healing time of the study group and the control group was (28.57 ± 5.08) days and (26.74 ± 5.57) days respectively, and no statistically significant difference existed between the two groups(P>0.05). The tubal patency rate of the study group and the control group was 76.2%and 78.9%respectively, and no statistically significant difference existed between the two groups (P > 0.05). The adverse events in both groups were mild, and the occurrence of the adverse events in the study group and the control group was 58.3% and 26.1% respectively, and the difference between the two groups was statistically significant (P <0.05). Conclusion Two kinds of interventional methods have the same clinical curative effect. However, the incidence of adverse events in the control group is lower than that in the study group. Therefore, in treating ectopic pregnancy perfusion chemotherapy with MTX only is recommend.
