Objective To explore the general characteristics of the psychological sub-health state and to analyze the factors pos-sibly leading to the psychological sub-health state in order to provide the scientific basis for the treatment and prevention of the psy-chological sub-health state .Methods The individuals with the physical examination in our hospital were performed the psychologi-cal heath survey .Among them ,1 712 cases of psychological sub-health were taken as the research group and contemporaneous 1 902 cases of normal health were taken as the control group .The Symptom Check List-90(SCL-90) was adopted to compare the two groups and the logistic regression analysis was adopted to analyze the risk factors possibly leading to the psychological sub-health occurrence .Results The average scores of 20 factors in SCL-90 in the research group were higher than those in the control group , the difference was statistically significant (P<0 .05) ,in which ,the scores of interpersonal relationship sensitivity (22 .1 ± 5 .7) ,para-noid(14 .1 ± 5 .2) and the others(17 .5 ± 6 .3) in the research group were significantly higher than the critical scores with obvious symptoms .The logistic regression analysis results showed that :the sleep quality(OR=1 .843) ,accidental injury(OR=2 .634) ,eco-nomical status(OR=3 .032 ,and professional type(OR=4 .684) were the independent risk factors of the psychological sub-health occurrence .Conclusion The local patients with psychological sub-health were more prominent in the more sensitivity of the inter-personal relationship ,paranoid and poor sleep ,especially the intellectuals ,individuals with poor sleep and the crowd with accidental injury are prone to develop psychological sub-health .

OBJECTIVETo optimize the hydrolysis process of linarin by response surface methodology, and to use the model of aldose reductase to study the acacetin's activity of aldose reductase inhibitory.

METHODThe model of acacetin enzyme in vitro was established by the determination of fluorescence absorption of NADPH, the inhibition rate of acacetin aldose reductase was calculated, and then the IC50 of hydrolysis was obtained. The hydrolysis process of linarin hydrolysis condition was optimized by using response surface method.

RESULTThe results indicated that the IC50 of acacetin (2.74 mg x L(-1)) was less than the IC50 of linarin (3.53 mg x L(-1)). Hydrolyzation time of 7.4 h, sulphuric acid concentration of 0.54 mol x L(-1) and the ratio of material to liquid of 3 : 1 were the optimum conditions.

CONCLUSIONHydrolyzate acacetin has preferable inhibitory activity of aldose reductase. The optimized hydrolysis condition of linarin is convenient to use with good predictability.

Objective]Based on 346 cases of PNS patients using glucocorticoids observed during treatment, the main symptoms, syndrome differentiation of syndrome type of traditional Chinese medicine(TCM) by induction, and discusses its the evolution regularity of TCM Syndromes.[Methods]Develop a unified observation table, then clinicians recorded symptoms, signs, tongue picture and type of pulse to log on to observe truthfully and un-mistakbly table, after the end of observation, comprehensive analysis by the four examination methods, using a unified standards for TCM syndrome type determination. Discussion after glucocorticoids treatment of patients with PNS TCM syndrome objective laws of evolution.[Result]First ,TCM syndrome evolution:the results show that:before hormone treatment, Qi deficiency of spleen and kidney and Yang deficiency of spleen and kidney have become the most important type of syndrome;hormone use initial stages 1~4 weeks, Qi deficiency of spleen and kidney, deficiency of Qi and Yin, when the hormone used for 5~8 weeks. Yin deficiency of liver and kidney and deficiency of Qi and Yin occupied the main position; during the hormone withdrawal stage, the deficiency of Qi and Yin increased significantly; in the hormone maintain stage it was mostly deficiency of Yin and Yang and Yang deficiency of spleen and kidney. As for demonstration, in hormone therapy before a lot of patients suffering from retention of water and turbid damp;After the treatment of 1~4 weeks it was mostly humid heat ,turbid damp and blood stasis;the accompanying symptoms were mostly humid heat, blood stasis and pathogenic factor of wind after the treatment of 5-8 weeks ;Miscellaneous accompanying symptoms were very conspicuous except retention of water in the treatment of hormone withdrawal stage; In the hormone maintaining stage, the highest proportion of blood stasis compared with others. The use of hormone therapy, humid heat and blood stasis were more prominent than others. Second, after the hormone treatment(1~8weeks) the relationship between efficacy and TCM syndromes: A total of 130 patients enrolled, the 96 patients with Yin deficiency syndrome, the rest of the patients had no deficiency of Yin syndrome. The results indicated that Yin deficiency syndrome group serum albumin and 24-hour urinary protein excretion efficacy than those without Yin deficiency syndrome group, with statistical significance.[Conclusion] Glucocorticoids should belong to pure Yang medicine in traditional Chinese medicine, the body under the action of pure Yang drugs are prone to Yin deficiency symptoms, suggests that the higher the sensitivity to drugs, the clinical remission rate is also higher. This can be applied in clinical glucocorticoids and observe the change of the patients with syndrome, early in the patients' sensitivity to the glucocorticoids.

Objective To study the changes and the significance of the frangible lymphocyte in patients with fulminant viral hepatitis and investigate the relationship between the degree of frangible lymphocyte and the severe of fulminant viral hepatitis. Methods 32 cases confirmed with fulminant viral hepatitis, 66 cases with chronic hepatitis have been studied. 15 cases children from 3 to 5 years old and 46 cases adults have been used with control groups. 100?l lymphocytes (1?106/ml) and 100?l tumor cells(1?105/ml) mixed with 100?l self-serum at 37℃ for 5min to 30min. The fragmental lymphocyte can defined as a frangible lymphocyte. The lymphocyte attached with tumor cell is undestroyed anything can be regarded as negative frangible lymphocyte. Less than 30 percent of lymphocyte attached with tumor cells is destroyed will be conformed as low-grade frangible lymphocyte, between 30 percent to 60 percent regard as mid-grade, and more than 60 percent as severe-grade mode. Results The equiform frangible lymphocyte is detected in fulminant viral hepatitis and other groups like that in SARS in 2003 years. There is none of children have frangible lymphocyte. Only 3 person’s lymphocytes show severe-grade frangible and 9 people display mid-grade in 46 adult individuals. Contrarily There is high of 46.9 percent of cases with fulminant viral hepatitis show severe-grade frangible lymphocytes, only 4 cases is negative and 3 cases is recovered in one months of them. The frangible lymphocytes in fulminant viral hepatitis are significantly lower than those in chronic hepatitis patients not only in mid-grade frangible but in severe type. There is no significant recovery of frangible lymphocyte from acute to recover in fulminant viral hepatitis, but the degree of the lymphocytes are closely relate to the state of an illness. Conclusion The percent of frangible lymphocytes in children is lowest among adult people, chronic hepatitis and fulminant viral hepatitis. The proportion of frangible lymphocytes in fulminant viral hepatitis is highest, and significantly higher than that in chronic hepatitis. The phenomenon of frangible lymphocytes may be an important characteristic of an innate immunology reaction of the body.

Objective To study the method for preparing the polyamine cotton fiber loaded with Cu2+ and to test the antibacterial effect of the cotton fiber. Methods The natural cotton fiber was treated through basification, epoxygenation, alkene amination and Cu2+ adsorption. 8 kinds of microorganisms were used for the bacteriostasis test.

Objective: To evaluate a self-rated health measurement scale-the revised version 1.0 (SRHMS V1.0).Method:2000 subjects, including university students, patients in the department of traditional medicine, patients with dermatosis and military retired cadre, received the assessment with SRHMS V1.0. Result: The test-retest reliability of the above four groups was 0.80-0.98. The Cronbach alpha was 0.93, equal-length Spearman-Brown was 0.74, Guttaman Split-half was 0.73. The correlation between each item and its dimension was high, that between item and other dimension was low; furthermore, the correlation between each dimension and the subscale it belong to was high, that between the dimension and other subscales was low. Factor analysis produced ten main factors that were consistent with the original theoretical structure about SRHMS V1.0. The correlation between total score of SRHMS and that of SF-36 was significant (r=0.53). People of different age group, of different marriage status, with different occupations or education background, of different economic class had different results in SRHMS V1.0, while there was no difference significantly between male and female, between with different races or residencies. Conclusion: SRHMS V1.0 has good psychometric quality and can be used in Chinese population.
