Objective:The aim of the present study was to examine the relationships between alexithymia, negative affect,and quality of life(QOL)of lung cancer patients receiving chemotherapy.Methods:51lung cancer patients receiving chemotherapy completed questionnaires of quality of life questionnaire for Chinese cancer patients receiving chemobiotherapy(QLQ-CCC),26-item Toronto alexithymia scale(TAS-26)and symptom checklist (SCL-90).Results:1)The patients had better score in QLQ(increased by 11%,P

0.05).The variced recurrence rate in 1- and 2-year were 12% (3/25) and 20% (5/25) in TH glue group,and 39.1% (9/23) and 86.9%(20/23) in control group (P

OBJECTIVETo study the correlation between the absorption rate constants of beta-adrenoreceptor antagonists in rat small intestinal segments and their molecular structural parameters.

METHODSThe net atomic charges and the molecular volumes of 11 beta-adrenoreceptor antagonists were obtained with the semiempirical self-consistent field molecular orbital calculation CNDO/2 method and Mont Carlo method respectively, using the minimum energy conformation obtained from the optimization of the standard molecular geometry with the molecular mechanics MM+ method. The stepwise multiple regression analysis was used to obtain the correlation equations.

RESULTSThe absorption rate constants of beta-adrenoreceptor antagonists in rat jejunum or ileum were well linearly correlated with the sum of the net charges of all hydrogen atoms and the molecular volumes. The beta-adrenoreceptor antagonist with higher lipophilicity, weaker hydrogen-bonding potential,and smaller molecular volume had greater absorption rate constants.

CONCLUSIONThe absorption rate constants of beta-adrenoreceptor antagonists in rat small intestinal segments are mainly related with their lipophilicity,hydrogen-bonding potential and molecular size.

Objective To investigate the expression and significance of B lymphocyte stimulator (Blys) and its receptor BAFF (BAFF-R) in peripheral blood mononuclear cells (PBMCs) from patients with systemic lupus erythematosus (SLE). Methods The expression of Blys and BAFF-R was measured by flow cytometry in 90 pa-tients with SLE,which was compared with that of 45 healthy controls. The relationships between the expression of Blys, BAFF-R and other laboratory parameters as well as disease activity were analyzed. Results The expression of Blys and BAFF-R in PBMCs from patients with SLE was significantly elevated compared to healthy controls (P <0.001), so did the active group (P < 0.001) and inactive group (P < 0.001 and P < 0.01). The expression of Blys in PBMCs from active SLE patients was higher than that of inactive patients (P <0.05). However,there was no statisti-cal difference of BAFF-R between the two groups. The expression of Blys in PBMCs was positively related to SLEDAI (r =0.728,P <0.001) ,IgG and IgM(r=0.691,P<0.001 and r =0.453,P<0.01) ,but negatively related to C3 and CA (r = -0.510, P < 0.001 and r = -0.312, P < 0.05). The expression of Blys in dsDNA positive group was higher than those of dsDNA negative group (P < 0.01). The expression of Blys and BAFF-R in Cl qAb positive group was higher than those of ClqAb negative group as well (P <0.01). Conclusion The expression of Blys and its receptor BAFF-R in PBMCs from SLE is elevated ,which may reflect the disease activity and is related to the pro-duction of autoantibody. They might be involved in the pathogenesis of SLE.

OBJECTIVETo predict the percutaneous drug permeability coefficients with modified regression equation.

METHODSThe semiempirical self-consistent field molecular orbital calculation AM1 method was used to calculate the quantum chemical parameters and the modified theoretical linear solvation energy relationship was used to obtain the regression equation of the permeability coefficients of drugs through human epidermis.

RESULTThe permeability coefficients (P) of 36 nonelectrolytes were well linearly correlated with their theoretical descriptors including molecular volume (V), hydrogen bond acidity (sum alpha(2)(H)), hydrogen bond basicity (sum beta(2)(H)) and polarizability index (pi(1)). The regression equation was logP=-6.790+1.571 V+0.1550 pi(1)-1.295 sum alpha(2)(H)-2.485 sum beta(2)(H)(n=36,r=0.9777).

CONCLUSIONThe modified theoretical linear solvation energy relationship can be used to predict the skin permeability of drugs.

OBJECTIVETo investigate the effects of physicochemical properties of drug on its permeability through buccal mucosa.

METHODSBenzoic acid, caffeine and hydrocortisone were selected as model drugs and their permeability coefficients through isolated porcine buccal mucosa were determined.

RESULTThe permeability coefficients of benzoic acid, caffeine and hydrocortisone through isolated porcine buccal mucosa were (1.01 x 10(-4)+/-1.64 x 10(-5))cm.s(-1)ì(2.75 x 10(-5)+/-1.79 x 10(-6))cm.s(-1) and (2.49 x 10(-5)+/-6.32 x 10(-6))cm.s(-1), which were 14,989 and 389 times as those through human skin, respectively.

CONCLUSIONThe permeability of drugs through buccal mucosa seems to be much better than that through human skin.

Seven emotions generation relates to the interaction between individual and external objective matters,which is accompanied with interaction between internal desire and external matters.The activity of seven emotions bases on essence of zang-fu organs,being regulated by five zang viscera.Heart is the upstream controller,liver is the key organ to maintain normal emotionds,spleen and stomach is the hub of emotional activities,lung is the auxiliary organ, kidney is origin of emotional generation.Five zang viscera's cooperation and interaction generate the seven emotions.

200 citrinin mutants were screened with the inhibition zone method from the transformants library of Monascus ruber M-7 by Agrobacterium-mediate DNA transfer, which contains more than 5,000 transformants.Then 53 mutants, whose citrinin contents ranged from 0.04?g/g to 154.57?g/g in the red fermented rice (RFR), were achieved by high performance liquid chromatography (HPLC).Color values of RFR prepared by these mutants were also detected.The results showed that there was a positive correlation between the citrinin content and the color value among the mutants.These results provide materials and research bases for ferrther studying the relationship between the production of citrinin and pigment of Monascus ruber at molecular level.
