This paper studies tile regulation of cytokines such as human tumor necrosis(Hu-TNF) and recombinant human interferon - (rHu -IFN - ) on activity of human polymorphonuclear neutrophils (PMN) against Candida albicans by determing numbers of colony - forming unit of Candida albicans. We detected that Hu - TNF and rHu IFN st did not interfere directly with fungal growth. These two cytokines enhanced PMN to inhibit Candida albicans growth. When preincubating PMN with Hu --TNF and rHu-IFN -togather, the activity of PMN against Candidaalbicans was synergically enhanced. The degree of enhancement of the activity of PMN againstCandida albicans was highly dependent on these two cytokines - PMN preincubation time. Thus,Hu -- TNF and rHu -- IFN -- have the ability to activate PMN, and the synergistic action of thetwo cytokines may prove clinically effective for increasing the ability of immuncompromised hosts against opportunistic fungal infectons.

Objective To study the role of tumor necrosis factor alpha(TNF ?), interleukin(IL) 6 and IL 8 in the pathogenesis of condyloma acuminatum(CA). Methods Double antibody sandwich ELISA was used to study the levels of TNF ?,IL 6 and IL 8 in 21 cases of CA. Results The results showed that the levels of TNF ?,IL 6 and IL 8 of the plasma in the patients were significantly lower than those of normal controls. The levels of TNF ?,IL 6 and IL 8 produced by peripheral blood mononuclear cells in response to LPS mitogen in vitro significantly decreased in comparison with those of normal controls. The levels of IL 6 and IL 8 of the wart tissues excised from 17 patients were significantly lower than those of normal tissue. No TNF ? was detected in the tissues of both patient and normal groups. Conclusion These findings suggest that the monocyte macrophage function of CA patients might be decreased systemically and locally which may contribute to the disorder of lymphocyte function. Improvement of the monocyte macrocyte function might have some significant effect on the prevention and treatment of CA.

Objective To investigate the role of HLA class II antigen of human monocytes in pathogenesis of herpes simplex virus-2 (HSV-2) infection. Methods Human monocytes were infected by HSV-2 (333 Strain). The cultured cells were collected at the first, third, 5th, and 7th days of post-infection. The expression of HLA class II antigen of the infected monocytes was measured by alkaline phosphotase anti-alkaline phosphotase method (APAAP). Results The expression of HLA class II antigen on the monocytes significantly decreased at the first day of post-infection,and then gradually increased and reached to the normal control level at the 7th day of post-infection. Conclusion HLA class Ⅱ antigen expression of monocytes was inhibited by HSV-2 infection at early stage, which may be one of means of virus escaping host immunity. The expression of HLA class Ⅱ antigen may play an important role in HSV-2 pathogenicity and immunity.

Methods By random cluster sampling, the mental status of 1902 army officers and soldiers were investigated according to the contents and parameters of "Chinese Military Mental Health Scale (CMMHS)", "Military Occupational Stress Scale" and "Military Personnel Scene-trait Coping Style Scale". Results 1) The total score of occupational stress and passive coping, and the score of each factor were significantly higher in the mentally unhealthy group than that in the healthy group (P

Objective To study the ways,mechanism,indication,curative effect of " Basket" skill applied in the interventional therapy for intracranial aneurysm. Methods Intracranial aneurysm with 1 : 1 ≥ neck/body ≥ 1 : 2 ," 3 D coil" was used to form a basket in it;in that with 1:2 > neck/body,common "2D coil" was applied. And the following coils were applied with hydrocoil or fibered coil combined with common platinum coil to increase the embol-ism density. Results In 156 cases with 158 aneurysms,143 aneurysms were 100% embolized (90. 5% ) ;131 ca-ses discharged with GOS 5 score(84.0% ),and 2 cases died ( 1.3% ). Conclusion " Basket" skill can increase the embolization density in aneurysm,reducing the residual of the neck,getting embolizated fully and improving the prognosis.

To compare the effects of polysaccharide nucleic acid fraction of bacillus calmette guerin (BCG-PSN) and thymopeptides on T-lymphocytes of normal and immunosuppressed mice, CD4+ and CD8+ T-lymphocyte subsets of single nucleic cell in thymus, spleen and peripheral blood were detected successively by flow cytometry after application of BCG-PSN and thymopeptides. Meanwhile, CD4+/CD8+ ratio was also calculated. The results showed that both BCG-PSN and thymopeptides could decrease the proportion of CD4+ CD8+ T-lymphocyte subsets in the thymus, at the same time increase CD4+ T-lymphocyte, CD8+ T-lymphocyte proportion in the three tissues. The fluctuation in amplitude was greater in thymopeptides group than that in BCG-PSN group. It is concluded that acting location of thymopeptides is in thymus, its stimulating action is stronger than that of BCG-PSN, while BCG-PSN not only accelerates the differentiation in thymus, but also has some direct stimulation to peripheral CD4+ T-lymphocytes, and can maintain CD4+/CD8+ ratio within normal range. So, BCG-PSN is safer.

Objective To develop a Chinese military psychosomatic health scale(CMPHS) and examine its reliability and validity. Methods Based upon the previous researches, the Scale was compiled according to open-ended inventory survey. The data was collected from 1050 subjects chosen by random cluster sampling. 60 of them were tested with the CPSHS at the same time, while 61 of them were retested with the CMPHS after two weeks. The reliability and validity were examined by exploratory factor analysis ( EFA) and correlation analysis. Results According to the factor analysis results, 11 factors were extracted, namely espiratory apparatus, alimentary system,skeletal and musculature,integument,regeneration and endocrine,nervous system, anxiety, depression, psy-choticism and family history. There were 91 items in the formal scale when one lie subscale was added. The correlation between subscales were 0. 103 ～ 0. 778 (P < 0. 01) , the correlation between subscales and total scale were 0.600 ～0.859(P<0.01). The test-retest correlation coefficients of total scale and subscales were 0.427 ～0.901 (P < 0.01); the Cronbach (α) coefficients were 0. 643 ～ 0. 935 (P < 0. 01) ; and the split-half correlation coefficients were 0. 349 ～ 0. 855 (P < 0. 01 ). The correlation coefficients were 0. 425 ～ 0. 979 (P < 0. 05 or 0. 01 ). Conclusion The Chinese military psychosomatic health scale has acceptable psychometrics properties on reliability and validity.
