The expression of heat shock proteins(HSPs) can protect against acute lung injury(ALI).However,HSPs are restrained from clinical application due to the toxicity of most of the former inductors.Glutamine,which also has the ability to induce the expression of HSPs,can protect against ALI and sepsis,and may serve as a candidate for clinical application.

Objective To investigate the in vivo effects of glutamine(Gln) on inflammatory cytokine release in murine peritoneal macrophages during sepsis. Methods Sixty Kunming mice were randomly divided into sham-operation group(Sham group,n=20),operation control group(Con group,n=20) and Gln-treatment group(Gln group,n=20).Sepsis was induced by cecal ligation and puncture in Gln group and Con group,and Gln(0.75 g/kg) or saline was immediately administered via single tail vein injection.Serum was collected and macrophages were harvested from peritoneal lavage at 6 h in these three groups.Intracellular and serum cytokines of tumor necrosis factor-?(TNF-?),interleukin(IL)-6 and IL-10 were detected by ELISA.The expression of TNF-? mRNA in macrophages was analyzed by RT-PCR,and the expression of heat shock protein(HSP) 72 in macrophages was evaluated by Western blotting. Results Gln group demonstrated significantly lower intracellular TNF-? and IL-6 levels than Con group(P0.05).The serum TNF-? level was significantly lower in Gln group than in Con group(P

Objective To evaluate the efficacy of discriminant function analysis for pericolic infiltration in colorectal cancer on enhanced 64-slice spiral CT and to improve the diagnostic accuracy and specificity of pericolic infiltration. Methods Dynamic enhanced 64-slice spiral CT was performed in 49 colorectal cancer patients (49 masses in total) before surgery. One or two slices were selected for each mass, with a total of 96 slices. The 96 slices were classified into two groups (pericolic infiltration or nonpericolic infiltration group) according to pathological data. Discriminant analysis was performed on the CT values between the mass and the corresponding pericolic tissue 5 mm from the mass at different time points as follows; 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, and 75 s. The discriminant function was calculated, and the pericolic infiltration determined by discriminant function and CT morphology were compared with the pathological results. The CT values in pericolic and non-pericolic infiltration groups at different enhancement time points were assessed using analysis of variance. Results The mean CT values ranged from (43. 6 ±7. 8) HU to (52. 3 ±0. 8) HU in the pericolic infiltration group, and ranged from (100.4±20.3)HU to(116.2±21.4)HU in the non.perieolic infiltration group.At 20 s and 40 s,the mean CT vshle8 were(43.6±27.8)HU and(50.9±27.8)HU in the perleolic infiltration group, (102.0±16.9)HU and(116.2 ±21.4)HU in the non-perieolic infiltration group,respectively.The mean CT value in the pericolic infiltration group was significantly lower than that in the non-pericolic infiltration group at all contrast enhancement time points(F=6.278,P<0.01).A diseriminant function Was obtained as follows:D=-3.450+0.023Xl±0.017X2-0.00lX12-0.001X22+0.002X1×X2. Based on the CT morphology of colorectal cancer,69 slices were identified correctly and 27 slices were fulsely interpreted.the sensitivity.speeificity and accuracy for perieolic infiltration determination were 82.5%,64.3%and 71.9%.respectively.Based on diseriminant function,85 slices were identified correctly and 11 slices were falsely interpreted.the sensitivity,specificity and accuracy were 85.0%.91.1%and 88.5%,respectively.Conclusion The discriminant function with dynamic enhanced 64-slice spiral CT can improve the diagnostic accuracy and specificity of perieolic infiltration in eolorectal cancer patients.

Objective:To prepare dendritic cell (DC)-cytokine induced killer (CIK) tumor vaccine using DCs of patients with nonsmall-cell lung cancer (NSCLC) harboring autologous tumor antigens and to observe its inhibitory effect on autologous tumor cells in vitro. Methods: Peripheral blood mononuclear cells (PBMCs) extracted from NSCLC patients were cultured into DCs and CIKs in presence of different cytokines. Cancer cells from the patients were cultured in vitro and were used to prepare different tumor antigens: tumor cell lysates, necrotic tumor cells and normally-grown tumor cells. The DCs were stimulated by OK-432 and the phenotypes of the DCs were analyzed by flow cytometer. Then the DCs were co-cultured with CIKs. The anti-tumor effect of DC-CIK was evaluated by MTT assay. Results: Compared with the DCs harboring the antigens of necrotic tumor cells and normally-grown tumor cells, DCs pulsed with tumor cell lysates had significantly higher expression of surface molecules such as CD1a (85.1?2.7), CD80 (80.0?4.4), CD83 (75.4?5.3), and HLA-DR(80.5?7.8, all P

Endophytic fungi were isolated from Macleaya cordata growing in Dabie Mountain by agar-block method, and then the endophytic fungi were grouped into different types based on their morphological characteristics, and thin layer chromatography (TLC) and high performance liquid chromatography (HPLC) were employed to determine whether the metabolic substances contained sanguinarine or not, and then preliminarily identified by morphological method. The results showed that the leaves hosted the largest number of endophytes (96 isolates) followed by the stems (57 isolates) and finally the roots (28 isolates), respectively. Based on morphological characteristics the endophytic fungi were grouped into 26 types in our study. TLC and HPLC results showed that there was sanguinarine in the metabolic substances of BLH 51 strain. According to the morphological characteristic, the BLH 51 strain was identified as Fusarium proliferatum. All these indicated that the medicinal plant M. cordata harbors abundant endophytes, which could be a new source for the search of active secondary metabolites.

OBJECTIVETo investigate the temperature change of scrotum caused by varicocele(VC) and its significance.

METHODSOne hundred and sixty-six VC patients were examined by infrared ray imaging and colored ultrasonic scanning, and the results were analyzed. Comparisons of the infrared ray images and the routine semen analysis of 106 of the patients were made between before and after the operation.

RESULTSThe difference in the infrared ray images between before and after the operation on the VC patients was significant (P < 0.01), and so was the difference in the results of semen analysis(P < 0.01; some of the items P < 0.05).

CONCLUSIONSThe infrared ray imaging, together with the semen analysis and colored ultrasonic scanning, had a directive value for the diagnosis and treatment of VC patients.
