Kawasaki disease, also known as infantile skin mucous membrane lymph node syndrome, is an acute vasculitis syndrome in pediatricdepartment. The lesion mainly involves medium and small arteries, particularly the coronary artery, being a major cause of pediatric coronary lesion and also a potential risk factor of coronary heart disease during later adulthood. Here the clinical data and treatment of one case of Kawasaki disease complicated with coronary aneurysm and 4 years later the occurrence of cardiocerebrovascular lesion (CCVL) were retrospectively analyzed, and the related literatures were reviewed and analyzed to approach the clinical characteristics of this disease complications. It is suggested that at early stage regular treatment should be applied and afterwards periodical follow-up should be performed; long-term monitoring coronary changes ought to be carried out to decrease the occurrence of CCVL accident.

BACKGROUND: Progressive body mass losses and physical strength decrease are common complications of malignant tumors, and they are important factors that affect the quality of life of the patients.OBJECTIVE: To probe into the curative effect of a Chinese herbal compound Yiqi Xiaozheng granules combined with antitumor drugs in the treatment of malignant tumors and its effect on the quality of life.DESIGN: A randomized controlled observation.SETTING:Clinical Tumor College of Peking University.PARTICIPANT: Totally 61 patients with malignant pulmonary carcinoma,breast or intestinal carcinoma hospitalized in the Wards of Integrated Traditional Chinese and Western Medicine of Beijing Cancer Hospital from June 1999 to March 2002 were recruited.METHODS: Altogether 61 cases of malignant tumor were randomized into the treatment group (treated with Chinese herbal compound Yiqi Xiaozheng granules supplemented with chemotherapy)(n=34) and the control group (treated with only chemotherapy was used)(n=27). The difference in curative effect, survival period with tumor and the quality of life of the two groups were observed. The comparison of the curative effects of the two groups was performed according to Clinical Curative Effect Criteria for Solid Tumors stipulated by World Health Organization: completely response, partly response, stable disease, and progressive disease. X-ray examination was performed on the patients before the therapy and two courses of treatment after the therapy to evaluate the curative effect. Physical strength grading was made according to the evaluation criteria of Eastern Oneology Cooperative Group of the United States. The two groups were graded before and after the treatment. The group with decreased grade after the treatment was considered to be improving, but the group with increased grade after the treatment was considered to be worsening.symptom before and after therapyparison of the curative effect of the two groups: The cure rate of the treatment group was higher than that of the control group (partial response rate,stability rate and progression rate of the two groups was 36% ,7% ;52%,survival with tumors: The mean period of survival with tumors of the treatment group was longer than that of the control group until March 2002ing: Physical strength grading status was better after the therapy in the treatment group than that in the control group [ In the treatment group, 9cases (26%)were ameliorated, 25 (74%)appeared stable , none was aggravated; in the control group, 1 case (4%) was ameliorated, 25(93%) appeared of qi-deficiency symptoms in traditional Chinese medicine before and after the treatment between the two groups. Symptoms such as sweating and qi deficiency manifested as disclination to talk, listlessness, debility, etc. were significantly reduced in the treatment group (The numbers of cases before and after the treatment were 20, 9; 17,9; 20,13 respectively). In the control group, the cases either were stable or showed an increase in symptoms (There were 13, 13; 14, 17; 18, 20 respectively before and after treatment).CONCLUSION: Compared with the control group, in the treatment of malignant tumors, Yiqi Xiaozheng granules supplemented with chemotherapy not only enhanced curative effect, but also improved the quality of life and prolonged the period of survival with tumors.

CCAAT/enhancer binding protein β (C/EBPβ) is a critical member of C/EBP family.C/EBPβ,based on the leucine zipper located in C terminal of the protein,can regulate transcriptional activities of downstream target genes involved in diverse cellular processes,such as proliferation and differentiation.Recently published studies have identified that C/EBPβ is essential in the decidualization of endometrial stromal cells.This review summarizes the roles and mechanisms of C/EBPβ during the courses of decidualization,which is aimed at providing novel insights for dysfunctional decidualization.

OBJECTIVE:To study the resistance physiological responses of seedling of Scrophularia ningpoensis to the stress caused by saline and alkali at different concentrations. METHODS:The seedling of S. ningpoensis was placed in the illumination in-cubator,in which the temperature was maintained at(20±2)℃,light-dark cycle at 13 h/11 h and illumination intensity at 2 000 lx. The alkali (NaHCO3) of 50,100,150,200 and 250 mmol/L and the saline (NaCl) of 50,100,150,200 and 250 mmol/L were poured once every 4 days for 16 consecutive days. The growth indexes(plant height,fresh weight,dry weight),chlorophyll (Chl) content,antioxidative indexes [superoxide dismutase (SOD),catalase (CAT),peroxidase (POD),hydrogen peroxide (H2O2),malonaldehyde (MDA),membrane penetration (RMP)],and osmotic regulation physiological indexes [soluble sugar (SS),soluble protein(SP)and proline(Pro)] of the seedling were determined. There set a blank control group(distilled water). RESULTS:For saline concentration higher than 50 mmol/L and alkali concentration higher than 150 mmol/L,the seedling height, fresh weight and Chl content were lower;for saline concentration higher than 100 mmol/L and alkali concentration higher than 150 mmol/L,the dry weight of the seedling was lower. For saline concentration of 50 mmol/L and alkali concentration of 150 mmol/L, the activities of SOD and POD were the strongest;for saline concentration of 150 mmol/L and alkali concentration of 50 mmol/L, the activity of CAT was the strongest. The contents of H2O2 and MDA increased and the content of SP decreased with the increase in saline-alkali concentration. The level of RMP increased therewith,that is to say,membrane stability decreased. For saline concen-tration higher than 100 mmol/L and alkali concentration higher than 150 mmol/L,the accumulation of SS terminated;for saline and alkali concentrations higher than 100 mmol/L,the accumulation of Pro terminated,however,the content of Pro was markedly high-er in the above-said alkali concentration than in that saline concentration. CONCLUSIONS:Saline-alkali stress causes the tissues of S. ningpoensis to produce active oxygen and its cytoplasmic membrane system to be damaged. Chl,enzymatic antioxidants such as SOD,CAT and POD,and osmoprotectants such as Pro and SS can buffer saline-alkali stress to some degree. The maximum concen-trations of NaCl and NaHCO3 that seedling of S. ningpoensis can tolerate are 50 mmol/L and 150 mmol/L respectively.

OBJECTIVE:To study the effects of exogenous abscisic acid(ABA)on salt-alkali tolerance of Scrophularia ning-poensis seedlings,and to provide theoretic evidence for cultivating S. ningpoensis in salt-alkali soil. METHODS:50 S. ningpoensis seedlings were divided into control group,salt-alkali group(75 mmol/L),salt-alkali(75 mmol/L)+ABA low-concentration,medi-um-concentration and high-concentration groups(10,50,100 μmol/L),with 10 plants in each group. 20 days after transplanting, the plants were sprayed with drugs every 4 days. Growth indexes of the plants(length of stem,fresh weight,dry weight,survival rate),physiological indexes [the contents of chlorophyll,soluble sugar (SS),soluble protein (SP) and free proline (Pro)],the contents of MDA and H2O2,the activities of antioxidase [the activities of SOD,POD,CAT,GR] and the contents of Na+ and K+in stem and root were determined in each group 2 weeks later. RESULTS:Compared with control group,stem height and survival rate of S. ningpoensis seedlings,SP,the contents of Na+ and K+ in the stem,the contents of Na+,CAT and GR in the roots were all decreased significantly in salt-alkali group;while chlorophyll,Pro,MDA and H2O2 contents,the content of K+ in the roots and the activities of SOD and POD were all increased significantly(P<0.05 or P<0.01). Compared with salt-alkali group,stem height of S. ningpoensis seedlings,fresh weight and chlorophyll content were increased significantly in salt-alkali+ABA medium-concentra-tion group,while MDA and the content of Na+ in the stem were decreased significantly;dry weight,the contents of SS and SP, the activities of SOD and CAT were increased significantly in salt-alkali+ABA low-concentration and medium-concentration groups, while the SS content was increased in salt-alkali+ABA high-concentration group;stem height and dry weight were decreased signifi-cantly in salt-alkali+ABA high-concentration group;Pro content of salt-alkali+ABA low-concentration and high-concentration groups were decreased significantly;H2O2,Na+ content in the roots were decreased significantly in salt-alkali+ABA low-concentra-tion,medium-concentration and high-concentration groups;while GR activity,K+ content in the stem and roots were increased sig-nificantly;POD activity were decreased significantly in salt-alkali+ABA medium-concentration and high-concentration groups. CON-CLUSIONS:The addition of a certain concentration of exogenous ABA can effectively increase salt-alkali tolerance of S. ningpoen-sis seedlings and strengthen the ability of the plant adapting to salt-alkali environment.
