Objective To explore the relationship between preoperative serum pro-adrenomedullin (pro-ADM) in the patients with closed rupture of small intestine,and postoperative secondary abdominal infection,and to study the value of postoperative serum pro-ADM in assessment of severity of postoperative secondary abdominal infection of this patients.Methods Eighty-five patients with closed rupture of small intestine treated in the emergency surgery from June 2014 to May 2015 were selected.According to the presence of postoperative abdominal infection or not,these patients were divided into infection group and non-infection group.The infection group was further divided into SIRS,sepsis,severe sepsis,septic shock subgroups as per the severity of infection.The levels of serum pro-ADM,interleukin-6 (IL-6),C-reactive protein (CRP) were determined and the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score was calculated at admission and the first day、the second day and the third day after operation.Comparisons of these biomarkers were carried out to find out the factors associated with postoperative abdominal infection.In addition,ROC curve was used to verify the factors for predicting the abdominal infection of these patients after operation.The relationship between serum levels of pro-ADM and APACHE Ⅱ score after operation was analyzed.The severity of abdominal infection after operation was assessed with laboratory findings.Results Compared with non-infection group,preoperative and postoperative serum pro-ADM (P =0.03,P ＜ 0.01),IL-6 (P =0.02,P ＜0.01) levels and APACHE Ⅱ scores (P ＜ 0.01,P ＜ 0.01) were significantly higher in infection group (P ＜ 0.05).In the infection groups,the postoperative levels of serum pro-ADM and APACHE Ⅱ scores were increased with the severity of infection increased (r =0.924),and the difference between the groups was statistically significant (P ＜ 0.05),but there were no significant differences in IL-6 and CRP levels between two groups.Conclusion (1) The serum levels of pro-ADM before operation has value in predicting the genesis of abdominal infection in these patients after operation.(2) The serum levels of pro-ADM after operation has value in severity assessment of abdominal infection in these patients after operation.

Objective To explore the role of CD73 in Toxoplasma gondii (T. Gondii) infection; To verify the host cells absent with CD73 would have less infection and replication of T. Gondii. Methods CD73 knockout and wild-type mice were infected with 20 cysts of ME 49 by oral gavage. The survival rate, clinic symptoms, pathology in the gut, and cytokine production were investigated in infected mice. Macrophages and dendritic cells with CD73-/- and CD73+/+ were infected with RH-YFP. The infective rates, the number of intracellular RH-YFP in the host cells, and the replication of intracellular RH-YFP were detected in these two type cells. Results CD73 knockout mice had a higher survival rate and milder clinic presentation with less morphologies in the gut in the acute T. Gondii infection compared with wild-type mice. CD73-/- macrophages and dentritic cells had less T. Gondii infection, and less intracellular parasite number and replication compared with CD73+/+ macrophages and dentritic cells in vitro. Conclusions CD73 as a GPI-anchored surface protein of host cell might be involved in forming the parasite vacuole, and promote the parasite's attachment and invasion of host eeUs. Host cells absence with CD73 would be less infection and replication of T. Gondii, and relative resistant parasites infection.

Objective To examine the differentially expressed invasion-related genes in two anchorage-independent uterine cervical carcinoma cell lines derived from the same patient using a cDNA array. Methods Two human uterine cervical carcinoma subclonal cell lines CS03 and CS07 derived from a single donor line CS1213 were established by limited dilution procedure. The two cDNA samples retro-transcribed from total RNA derived from CS03 and CS07 cells were screened by a cDNA microarray carrying 234 human cell-cycle related genes and 1011 human signal transduction and membrane receptor -associated genes, scanned with a ScanArray 3000 laser scanner. Results The cDNA microarray analysis showed that 12 genes in CS03 were up-regulated compared to CS07, and 24 genes in CS07 were up-regulated. The function of a number of differentially expressed genes was consistently associated with cell-cycle, cell proliferation, migration, apoptosis, signal transduction and tumor metastasis, including p34cdc2, TSC22, plasminogen activator inhibitor I (PAI-1)and desmosome associated protein(Pinin). Conclusion Multiple genes are differentially expressed in uterine cervical carcinoma cell lines even came from the same patient. It is suggested that these genes are involved in the different phenotypic characteristics and development of cervical carcinoma.

To examine the effects of ischemia and anoxia on cell activation and cell cycle of astrocytes in vitro, the cell cycles and the proliferation of astrocytes in different time points after ischemia and anoxia were studied by flow cytometry and BrdU labeling and the expression of GFAP and cyclin D1 was detected by the fluorescence immunochemistry. After ischemia and anoxia in vitro, the astrocytes in S phase were significantly increased as compared with those in the normal group and the proliferating ability of the astrocytes was highest 6 h after the treatment as revealed by BrdU pulse labeling, but the astrocytes in S phase and proliferating ability were decreased after 6 h. At the early stages of ischemia and anoxia, the positive staining intensity of GFAP was increased, peaked at 6th h, while 12 h after the ischemia and anoxia, the positive staining intensity of GFAP became weak, and the expression of cyclin D1 was gradually increased after the ischemic and anoxic damage. It is concluded that astrocytes are activated to proliferate and enter new cycle events by ischemia and anoxia, and cyclin D1 is implicated in the proliferation and repair of astrocytes. The cell cycle events are closely associated with the proliferation and activation of astrocytes.

AlM: To compare the results of 4 methods for measuring angle of exodeviation in the three types of intermittent exotropia, including when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test.
METHODS: Prospective case series study. Sixty-five patients with intermittent exotropia between June 2013 and June 2014 were enrolled in the Department of Ophthalmology, Affiliated Hospital to Qingdao University, included 37 males and 28 females with average age ( 12. 5 ± 6. 2 ) years. All the patients were measured when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test. lntermittent exotropia was divided into basic type, convergence insufficiency type and divergence excess type, which was based on the different result of between the distance and near measurements. The One-way test was applied to analyze the four methods of measuring angle of exodeviation in the three types of intermittent exotropia. LSD - t test was applied to compare the differences between each two methods in each type.
RESULTS: The distance exodeviations tested with looking at indoor distance target of 6m, looking at indoor distance target of 30m , looking at outdoor far distance target, after 1h diagnostic occlusion test were basic type (45. 4 ± 21. 0, 55. 0 ± 15. 0, 64. 68 ± 17. 7, 68. 75 ± 16. 6PD), convergence insufficiency type (33. 3 ± 14. 0, 44. 9 ± 12. 9, 43. 6±11. 8, 54. 6±11. 2PD), divergence excess type (55. 6± 17.4, 66.3±18.8, 76.9±16.4, 78.1±15.6PD). There were obviously differences between each two methods in each type ( basic type F = 9. 649, P = 0. 00; convergence insufficiency type F=6. 886, P=0. 001; divergence excess type F = 7. 989, P = 0. 00 ). Compared with looking at indoor distance target of 30m, looking at outdoor far distance target ( basic type P=0. 044, divergence excess type P = 0. 048 ) and after 1h diagnostic occlusion test (basic type P=0. 04, divergence excess type P=0. 027) had the statistical difference in the basic type and divergence excess type, and there was no obviously difference between looking at outdoor far distance target and after 1h diagnostic occlusion test ( basic type P=0. 353, divergence excess type P=0. 815). Compared with the other three measurements, 1h diagnostic occlusion test can elicit larger angle of deviation in the convergence insufficiency type.
CONCLUSlON: Both measurement with looking at outdoor far distance target and after 1h diagnostic occlusion test can elicit the larger angle of deviation in the basic type and divergence excess type; The measurement with after 1 hour diagnostic occlusion test can elicit the larger angle of deviation in the convergence insufficiency type.

BACKGROUND: Herbal wines are an important part of the traditional Chinese medicine. The traditional medicated wine, lishizhen herbal wine,which can strengthen the immune function, has long been used for some chronic diseases. But,its mechanism remains unclear.OBJECTIVE: To explore the immune pharmacodynamics of lishizhen herbal wine and to observe its effect on the immune organs (spleen,pancreas) and lymphocyte transformation rate in mice.DESIGN: A randomized controlled experiment based on the observation of the experimental animals.SETTING: Department of integrated traditional Chinese and western medicine and the department of pharmacology of a university hospital MATERIALS: The experiment was completed at the Central Laboratory of Zhongnain Hospital of Wuhan University from September 2000 to December 2000. A total of 90 healthy Kuming mice were involved in the study.METHODS: Different doses of the herbal wine,cartinellin and the same volume of distilled water were given to the experimental animals. The drug administration was orally injected directly to the stomach of the animals once a day and 10 days consecutively. One hour after the last administration,the animals were put to death. Then,the thymus gland and the spleen were taken out and weighed to calculate the indexes of the thymus gland and the spleen. In the last three days of the administration phytohemagglutinin(PHA)was injected intramuscularly at a dose of 10 mg/kg once per day. Two hours after the last administration, the tails of the mice were cut out, the blood samples were taken to perform the Wright' s staining,and 100 lymphocytes were counted under immersion and the transformation rate was calculated.MAIN OUTCOME MEASURES: Primary results: ① The effect on the immune organs of normal mice; ② The effect of PHA on stimulating the lymphocyte transformation in mice. Secondary results: ③ The death condition of the experimental animalsRESULTS: Different doses of the herbal wine increased the spleen index in different degrees. The effect of medium dose group was obvious[(3.71± 0.78) g/kg] (P <0.05),and the thymus gland index increased a little (P>0.05). The cartinellin in the positive control group increased the spleen index[(3.79±0.91 ) g/kg] and there was no impact on thymus gland index. The transformation rates of the lymphocytes of different groups were increased to a different degree and presented a good quantity-effect relationship,especially the group administered a large dose[(45±14)%] (P<0. 01).CONCLUSION: Lishizhen herbal wine has an effect of increasing cellular immune function.

Objective:To examine the expression of CLC-3 in colorectal tissues and the effect of CLC-3 on the viability and invasion of colorectal cancer (CRC) SW480 and SW620 cells. Methods:The mRNA levels of CLC-3 in CRC cell lines were determined by RT-PCR. CLC-3 expression was inhibited by adding DIDS or NPPB to the CRC cells. Subsequently, cell viability and invasion were assessed by CCK-8 assay and Transwell assay, respectively. In addition, the effects of DIDS and NPPB on the Wnt orβ-catenin signaling pathways were de-termined by Western blot analysis. Results:The mRNA level of CLC-3 was remarkably increased in the CRC tissues compared with that in normal colorectal tissues (P<0.05) and was positively correlated with the T stage of CRC. The blockade of CLC-3 inhibited the viability and invasion of CRC cells (P<0.05). The expression ofβ-catenin, C-myc, cyclin D1, Ki-67, and survivin were evidently reduced by the in-hibition of CLC-3 (P<0.05). Conclusion:The inhibition of CLC-3 decreases the cell viability and invasion of CRC cells by reducing the ex-pression of the proteins related to the Wnt orβ-catenin signaling pathway.
