Objective To evaluate effects of pretreatment with glutamine on lung injury induced by intestinal ischemia/reperfusion(II-R) in rats. Methods Glutamine or saline were injected through tail vein before the model of intestinal ischemia/reperfusion in rats were established.The gene expression of intercellular adhesion molecule-1(ICAM-1) and heat shock protein-70(HSP-70) were tested with RT-PCR methods.The levels of heat shock protein-70 in the lung were measured with Western Blotting.Myeloperoxidase and malondialdehyde and pathological changes were also measured. Results The gene expression of heat shock protein-70 was enhanced by pretreatment with glutamine,and the level of HSP-70 was parallelly increased.Nevertheless,MPO,MDA and the gene expression of ICAM-1 were inhibited. Conclusion Pretreatment with glutamine can lessen the lung injury induced by intestinal ischemia/reperfusion in rats,the induction of HSP-70 gene may be one of the potential mechanisms.

Objective To quantitatively evaluate the metabolic changes in posterior cingulated cortex and left basal ganglia in patients with liver cirrhosis before and after liver Transplantation (LT).Methods A total of 22 controls and 37 cirrhotic patients listed for LT were enrolled in the study. Brain MRS (PRESS sequence) and neuropsychological (NP) tests were performed in all subjects. Eighteen patients were followed up at 1 month and 3 month after LT. The NP parameters including number connection test-A ( NCT-A), digital symbol test (DST) and symbol digital test (SDT) were measured. MRS metabolic contents were measured automatically at posterior cingulate cortex (PCC) and left basal ganglia (LBG).Independent t-test was used to compare the parameters of NP test and MRS metabolites between the 2 groups. The changes of the parameters before and after LT were compared using analysis of variance.Pearson correlation test was also used to analysis the relationship between NP test parameters and MRS metabolites. Results ( 1 ) Before LT, significant difference of metabolites was found in the PCC between the two groups [ NAA/Cr(1.96 ±0.21, 1.73 ±0. 12), Cho/Cr(0. 65 ±0. 12,0. 83 ±0.09), mI/Cr (0.41 ±0.14,0.72±0.11), Glx/Cr(2. 37 ±0. 38,1. 92 ±0. 32) (t= -5.42,5.96,8.62,-4.72,P<0.01)].And statistical significance also were found in LBG between the 2 groups [ Cho/Cr (0. 63 ± 0. 16,0. 77 ±0. 10), mI/Cr(0.38 ±0. 17,0.53 ±0.21), GIx/Cr(1.70 ±0.36,1.29 ±0.30), (t =3.64,3.07,-4.58 ,P < 0. 01 )]. (2)Compared with controls, the patients before LT had longer NCT-A reaction time [ (58. 17 ±19. 12) s,(37.68 ±8.02) s,t =4. 14,P<0.01], lower scores of DST (36.67 ±9.91,55.36 ±9.27,t = 4.60,P<0.01) and SDT (31.67 ±9.49,50.73 ±8.34,t = 4.652,P<0.01) before LT. All the scores of NP tests changed significantly at 1 and 3 month after LT compared with those before LT[ NCT-A (53.06±12.71) s,(35.72 ±5.20) s,F =33.554,P <0.01 ], DST(41.89 ±8. 17,54.39 ±5.69,F =85.772,P<0.01),SDT(37.44±7.68,49.39±5.65,F=83.061,P<0.01)]. (3) In the 18 patients who were followed, Cho/Cr [ PCC (0. 90 ± 0. 14,0. 92 ± 0. 08, F = 38. 178, P < 0. 01 ); LBG (0. 81 ± 0. 08,0. 80 ±0.09,F =9.447,P <0.01)] and Glx/Cr [ PCC(1.86 ±0.32,1.75 ±0.25,F = 19.420, P <0. 01 ); LBG( 1.30 ±0. 20,1.23 ±0. 25 ,F = 17. 952,P <0. 01 ) ] recovered at 1 month after LT, while the mI/Cr [PCC (0.39±0.15,0.71 ±0. 10,F =75. 186,P<0.01) ;LBG (0.47 ±0.25,0.61 ±0.27,F =8. 027, P < 0. 01 ) ] recovered at 3 month after LT. (4)mI/Cr of cingulate cortex correlated significantly with NCT-A, DST and SDT (r= -0.743, 0.597, 0.615, P<0.01 ) before LT. Conclusion Cerebral metabolic changes in patients with liver cirrhosis is reversible and MRS of the posterior cingulate cortex is a helpful method in following up the changes after LT. mI/Cr is a useful indicator to predict the brain changes of cirrhotic patients before and after LT.

To report a case of 16-month-old boy with anhidrotic ectodermal dysplasia with immunodeficiency who experienced disseminated herpes simplex infection. From 2 months of age, the patient experienced multiple pyrexial episodes of undetermined origin, which responded well to anti-inflammatory agents after undressed. Abnormal sweat with dry skin was noted; therefore, the skin biopsy of right axilla was performed at 7 months of age, and suggested a diagnosis of anhidrotic ectodermal dysplasia. Since 6 months of age, he developed recurrent upper respiratory infections and 2 episodes of pneumonia. Twenty days before, several glossal erosions occurred in the patient, supervened by painful and erosive eruptions and numerous blisters around the mouth and both hands with hyperpyrexia. Four days before, the patient was transferred to the department owing to skin lesion exacerbation. Cutaneous examination showed multiple crested or ulcerated plaques distributed eriorificially (mouth and nasal cavity) on the face. Several irregular, demarcated ulcers were scattered on the buttocks, scrotum and lower limbs, surrounded by grouped and umbilicated vesicles arising on erythema. Both hands were swelling, crusting and painful. Dentition was abnormal, and the patient had only 2 upper conical incisors. Routine investigation revealed that white cell count and C-reactive protein extremely elevated. Immunologic profile showed an abnormal distribution of lymphocyte subsets with decreased CD3+ T cells, CD8+ T cells and NK cells. Serum IgM level was slightly low. IgM antibodies to herpes simplex virus type 1 (HSV-1) were detected by serological testing. Based on the above-mentioned features, a diagnosis of anhidrotic ectodermal dysplasia with immunodeficiency and disseminated herpes simplex infection was confirmed. The patient was resolved favourahly after intravenous ganciclovir and antibiotics for 3 weeks without relapse of skin lesions.
