Medical Journal of Chinese People's Liberation Army 1982;0(03):-
As a common and frequently encountered dermatosis, psoriasis has been attracted the attention of dermatologists worldwide. In the past 30 years, radioimmunoassay, immunohistochemistry and molecular biological techniques were employed to determine the holistic levels of neuro immune protein (NIP), cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), and cAMP/cGMP ratio in epidermis and dermis and body fluid (blood and urine), as well as the expression status of CD44, heat shock proteins (HSP) and nerve growth factor (NGF) in skin lesions of the patients with psoriasis and the healthy volunteers. The regulating function of autonomous nervous system was examined by analyzing the variability of heart rate (HRV). In addition, the sleeping status of psoriasis patients was compared with that of normal subjects by polysomnography. Furthermore, a series of surveys from the psychological prospect, including type A personality, depression, anxiety disorders and stressful life events, were performed among psoriasis patients. All the basic researches and clinical studies listed above have indicated that psoriasis is a kind of psychosomatic disease; and psoriatic patients are suffering from a maladjustment of the holistic regulating function in different degrees. It has been proved in the long-term clinical practices that the side effect of the total medicinal therapy exceeds the positive effect. It is recommended that great efforts should be given to provide the patients with effective cognitive education and psychological therapy. As a result, patients can release their tense and mental pressure by themselves. In summary, on the basis of a safe and simple medication therapy and well adjustment of holistic status, psoriasis patients can achieve satisfactory effect, prolonged duration of remission and improved their quality of life.

Journal of Chongqing Medical University 2007;0(09):-
Objective:To construct prokaryotic expression vector of mutant nm23-H1(S120G,S120G-P96S, S44A), and then express and purify the proteins. Methods: Mutant nm23-H1 fragments were amplified by PCR. The prokaryotic expression vectors of pET28a-nm23-H1 were constructed by gene recombination technique and verified by restriction enzyme analysis and sequencing. The positive clones were transformed into E. coli BL21(DE3) and soluble analysis of the expression was conducted in these systems. The proteins were purified by nickel column chromatography and identified by Western blot. Results: The sequences and open read frames of all the pET28a-nm23-H1 were completely correct. After transforming, these plasmids could express the target proteins. The protein production was very high. Among these mutant proteins, S44A was soluble expression and S120G was partly soluble. However, S120G-P96S was mostly in the inclusion bodies. The molecular weight of these mutant proteins was 20 kD detected by Western blot, which was as the same as the objective protein. Conclusion: We have succeeded in constructing the prokaryotic expression vectors of pET28a-nm23-H1(S120G, S120G-P96S, S44A), and the S120G and S44A proteins can be used in following studies. However, S120G-P96S protein which expressed in this system may not be suitable for the following studies.

[Objective] To explore the culture conditions of inducing callus from tissue of Aristolochia contorta Bge (ACB). [Methods] The leaves of ACB were used as the explants. Basic medium (including 1/2 MS medium, MS medium and modified MS medium) containing corresponding phyto-hormones was applied for the induction of ACB callus. The influerices of different culture conditions such as three kinds of basic medium, different pH values and addition of different kinds of phyto-hormones at different concentrations into the basic medium respectively or simultaneously, on the callus induction of ACB were observed. [Results] (1) After the three kinds of basic medium were added with the phytohormones of 0.1mg/L kinetin (KT) and 0.2mg/L ?-naphthalene acetic acid (NAA) , a large amount of ACB calluses were induced in the MS medium and modified MS medium, while ACB calluses did not occur in the 1/2 MS medium. (2) When the pH value of the culture medium composed of modified MS medium and 0.1mg/L KT and 0.2mg/L NAA was at 5.8, 7.0 and 8.0, a large amount of ACB calluses were induced in the medium with pH value being 7.0 and 8.0 while a few calluses occurred in the medium with pH value being 5.8. (3) ACB calluses were induced in modified MS medium with NAA added , but calluses did not occur in modified MS medium with KT added. When the modified MS medium was added with different kinds of phyto-hormones at different concentrations, ACB calluses were loose in the medium with high-concentration NAA and this did not benefit to the differentiation of buds for too fast cell division, and the callus induction rate was low in the medium with low-concentration NAA. The optimized culture medium was modified MS medium with 1mg/L KT and 0.5mg/L NAA added. [Conclusion] The optimum culture conditions of inducing callus from ACB tissues are: MS medium or modified MS medium with 1mg/L KT and 0.5 mg/L NAA added being the culture medium, and pH value being 7.0-8.0.

Objective To study the difference on personality characteristics between childhood patients with psoriasis and healthy children. Methods Forty seven children (7-15 years old) suffering from psoriasis served as patient group, and fifty two healthy students (7-15 years old) served as normal control group. The personality character of all the children in both groups were assessed by Eysenck personality questionnaire for children (EPQ-C), and the T scores of EPQ were then compared between the two groups. Results The N scores (represent psychoneurotic tendency of the subjects) of patients with psoriasis were significantly higher than that of normal controls (t=4.624, P0.05). The E scores (represent extro-introverted tendency of the subjects) of the children in patient group was lower than that in control group, but no significant difference was found between girls and boys in the patient group. Significantly more children with introversive-unsteady personality were found in patient group (25.5%) than in control group (7.7%, ?2=5.798, P
