Objective To evaluate the strengthening and restoring effects and hepatoprotective effect of Eclipta extracts. Methods Sixty Kunming mice were randomly divided into control group, low-dose Eclipta group, high-dose Eclipta group, cyclopho9phamide(CY) group, low-dose Eclipta CY group and high-dose Eclipta CY group(n = 10). Eclipta 8 g·kg~(-1)d~(-1) or 4 g·kg~(-1) · d~(-1) were administered by oral gavage for 7 d. Immunosuppression mouse models were established by intraperitoneal injection of 0. 05 g/kg CY on the fourth day of administration. The effects of Eclipta extracts on thymus index, spleen index and carbon clearance index in both normal mice and immunosuppression mice induced by CY were tested, and those on proliferation of lymphocyte and T cells induced by ConA were examined. Based on these data, strengthening and restoring effects of Eclipta were observed. Besides, 70 Kunming mice were randomly divided into control group, low-dose Eclipta group, high-dose Eclipta group, CCl_4 group, DDB group, low-dose Eclipta CCl_4 group and high-dose Eclipta CCl_4 group. 20 g·kg~(-1)·d~(-1) and 10 g·kg~(-1) ·d~(-1) Eclipta were administered by oral gavage for 7 d. Hepatic injury mouse models were established by intraperitoneal injection of 10 mL/kg CCl_4 2 h after the last administration. The effects of Eclipta extracts on serum ALT, MDA, TP and T-Bil levels in both normal mice and hepatic injury mice induced by CCl_4 was tested, and those on the viability of the primary culture hepatocytes were determined. Based on these data, hepatoprotective effect of Eclipta was observed. Results Eclipta extracts increased thymus index and carbon clearance index in both normal mice and immunosuppression mice induced by CY, promoted proliferation of lymphocyte and proliferation of T cells induced by ConA, reduced serum ALT and MDA levels in hepatic injury mice, and improved the viability of the primary culture hepatocytes. Conclusion Eclipta herb has strengthening and restoring effects and hepatoprotective effect.

Objecave To explore the protective effect of active component of Eclipta on hepatic injury induced by Concanavalin A(ConA)in mice. Methods Mouse hepatic injury models were established by injection of ConA(15 mg/kg)via tail vein.The effect of Eclipta extracts on serum alanine aminotransferase (ALT) and liver histology in both normal mice and hepatic injury mice was examined.A pure compound was obtained by means of bioactivity-guided isolation,and IR,~(13)C-NMR, ~1H-NMR,~1H-~(13)C HMBC and ~1H-~(13)C HMQC were used for structural identiffcation. Results Eclipta extracts decreased serum ALT in hepatic injury mice induced by ConA.and demonstrated anti-apoptosis effect induced by ConA in hepatoeytes.Wedelolaetone,a eoumarin,was isolated from Eclipta,and its structure was identified on the basis of spectroscopic analysis.Wedelolactone inhibited ConA-induced T cell proliferation selectively,and completely antagonized the effect of ConA at the concentration of 10μg/mL. Conclusion Eclipta herb has hepatoprotective effect.Wedelolactone,the anti-inflammatory and anti-apoptosis active component of Eclipta,might serve as a lead compound for developing new antiinflammatory drugs.

Objective To study the influence of PYLL on life span of residents. Methods The reduce of potential life span in Kunshan residents from 1982~1999 was analysed between the male and female. Results The life span reduced significantly in injury, poisoning and c ancer, which accounted for over 56% of total causes o f death in PYLL, especially, over 60 % in male. PYLL rate in male was higher than that in female. PYLL rate in male a nd female (except brain blood vessel disease) from 1991~1999 was lower than tha t from 1982~1990. It was consistent with increasing of old age population pr oport ion and prolonging of expected life span in Kunshan residents year by year. Conclusions The reasons that causes to death of residents were injury a nd poisoning and cancer.

Objective To retrospectively analyze the cardiac systolic synchrony and cardiac function in patients with chronic heart failure (CHF) by gated SPECT myocardial perfusion imaging (GSMPI). Methods (1) From January 2010 to February 2015, 123 cases including 82 CHF patients (57 males, 25 females, age (59.5±11.0) years) and 41 healthy people (control group; 27 males, 14 females, age (33.8±5.2) years) were enrolled in this retrospective study. According to the New York Heart Association (NYHA) classification, the CHF patients were classified into grade Ⅰ-Ⅳ groups. The systolic synchrony and cardiac functional parameters including PHB, PSD, LVEF, EDV, summed rest scores (SRS) were acquired by Emory Cardiac Toolbox software. Differences of PHB, PSD and LVEF were compared between the CHF group and the control group using two-sample t test. The difference among the four CHF groups was compared by one-way analysis of variance. The difference of some clinical factors was compared between the two groups with and without damage of systolic synchrony. The relationship between the cardiac synchrony and myocardial perfusion was analyzed by Pearson correlation analysis. Results There was no obvious difference of PHB and PSD between the grade Ⅰ CHF patients and the control group (t=-1.502 and -0.448, both P>0.05), while LVEF was significant different (t=10.419, P<0.05). Significant difference of PHB, PSD and LVEF existed between the grade Ⅱ-Ⅳ CHF patients and the control group (t values: from -27.250 to 32.723, all P<0.05). There were significant differences of PHB, PSD and LVEF among the 4 CHF groups (F=118.05, 4.13 and 154.37; all P<0.05). The differences of LVEF, EDV and SRS were significant between the patients with and without damage of systolic synchrony (t=9.57, 10.85, 18.87, all P<0.05). The ratios of damage in systolic synchrony in grade Ⅰ-Ⅳ CHF patients were 8.7% (2/23), 60.0%(12/20), 15/18 and100% (21/21), respectively. PHB and PSD were both positively correlated with SRS (r=0.808 and 0.773, both P<0.05). Conclusions The damage of systolic synchrony are getting severer from patients with NYHA grade Ⅱ to patients with NYHA grade Ⅳ. The damage could be accompanied by the heart failure progression. Diabetes mellitus, LVEF, EDV, ESV, and SRS are related to the damage. The myocardial perfusion damage is positively correlated with the damage of cardiac systolic synchrony. GSMPI is useful to early diagnosis and treatment of heart failure.

Objective To evaluate the effectiveness of professional nurses in atrial fibrillation (AF) anticoagulation management system.Methods 217 consecutive patients with nonvalvular AF were enrolled.All patients received warfarin therapy for 3-6 months after catheter ablation for AF,who were divided into experimental group (n=102) and control group (n=115) by random digits table.The patients of control group adjusted their warfarin doses by following doctor's advice when discharged and by visiting the outpatient clinic regularly after discharged.The patients of treatment group adjusted their warfarin doses under the guidance of one well-trained nurse.Days of the international normalized ratio (INR) value achieved therapeutic anticoagulation range (2.0-3.0) for the first time,the effective anticoagulation rate that defined as more than 70% of INR values between 2.0-3.0 after titration period,the ratio of times of INR value 2.0-3.0 to total times after titrating and INR monitoring frequency were compared between the 2 groups.Results In treatment group,days of the INR value achieved therapeutic 2.0-3.0 for the first time were less than that in control group (8 d vs.15 d,P<0.01),the effective anticoagulation rate [45.1%(46/102)] and the ratio of times of INR value 2.0-3.0 to total times after titrating (67.6%±18.5%) was significantly higher than that in control group [31.3%(36/115) and 62.0%±23.1% respectively,P<0.05].INR monitoring during the whole period and after titrating were more frequently in treatment group [(9.4±2.2)times vs.(8.4±2.7) times,P<0.05;(7.9±2.4) times vs.(6.3±2.8) times,P<0.01].The number of patients in treatment group who monitor INR less than 3 times after titrating was larger than that in control group (18 vs.1,P<0.01).Conclusions The participation of professional nurses in atrial fibrillation anticoagulation management system was helpful not only in achieving INR 2.0-3.0 more quickly but also in improving the effective anticoagulation rate.
