To analyze and compare the protective effects of active components in different ethyl acetate extracts (EAEEPs) from Eclipta prostrate, in order to study the comparison of materials bases protecting normal human bronchial epithelial (NHBE) cells. The MTT assay was taken to compare the protective effect of different EAEEPs on cigarette smoke extracts (CSE) -induced NHBE cells. The ultra-performance liquid chromatography (UPLC) was applied to analyze the content of phenolic acid, coumaric grass ether and flavonoid in EAEEPs. According to the results, all of the eight EAEEPs (0-200 mg x L(-1)) showed certain protective effect on NHBE cells, with statistical difference. Specifically, the total mass of EAEEP VII (89.15 mg x L(-1)) and EAEEP VIII (57.44 mg x L(-1)), which showed the strongest activity, was not the highest, while EAEEP III (132.25 mg x L(-1)) displayed the highest total mass. In the combination with the "component structure" theory, the analysis showed a significant difference in the mass structure among phenolic acid, coumaric grass ether and flavonoid in EAEEP VIII and EAEEP VIII, which were 1.0: 1. 0: 0.5 and 1.0: 1.9: 0.8, respectively. The results suggested a specific optimal "component structure" relationship may exist in EAEEP, which could provide reference for the material base study and quality control.

OBJECTIVETo observe the effect of low molecular weight heparin calcium (LMWHC) combined Compound Danshen Injection (DI) on nephrotic syndrome patients with early onset severe preeclampsia.

METHODSTotally 80 nephrotic syndrome patients with early onset severe pre-eclampsia were randomly assigned to four groups voluntarily, i.e., Group A (22 cases, treated by magnesium sulfate), B (19 cases, treated by magnesium sulfate plus LMWHC), C (21 cases, magnesium sulfate plus DI), D (18 cases, magnesium sulfate plus LMWHC and DI). Umbilical arterial S/D ratios, amniotic fluid index (AFI), prolonged gestational age, placenta weight, neonatal weight, and Apgar score were compared among the four groups.

RESULTSCompared with before treatment in the same group, umbilical arterial S/D ratios decreased in the four groups (P <0. 05). AFI decreased in Group A, while it increased in Group B, C, and D (P<0. 05). Compared with Group A at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group B, C, and D (P <0. 01 , P <0. 05). Prolonged gestational age and neonatal weight were increased in Group B, C, and D (P <0. 01, P <0. 05). Placenta weight were increased in Group B and D (P <0. 05). Apgar scores at 1 and 5 min were improved in Group D (P <0. 05). Compared with Group B and C at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group D (P<0. 05). Compared with Group B, prolonged gestational age and placenta weight were decreased in Group C, but prolonged gestational age and placenta weight were increased in Group D (P <0.05). Compared with Group C, prolonged gestational age, placenta weight, and neonatal weight were increased in Group D (P <0. 05).

CONCLUSIONTreatment of nephrotic syndrome patients with early onset severe pre-eclampsia by LMWHC combined DI could prolong gestational ages, obviously improve prenatal outcomes, with better effect obtained than using any of them alone.

OBJECTIVETo analyze the clinical effectiveness of Compound Danshen Injection (CDI) in treating patients with early onset severe preeclampsia.

METHODSOne hundred and twenty patients with early onset severe preeclampsia were recruited and their gestational age ranged between 26 and 34 weeks. Sixty patients who volunteered to receive CDI were recruited as the treatment group, while 60 inpatients were recruited as the control group at the same time period. The routine therapy was given to those in the control group. CDI was intravenously dripped to those in the treatment group additionally by adding in 250 mL 5% glucose injection, once daily. The treatment for all lasted for 7 successive days. The D-dimer (DD), fibrinogen (Fg), hematocrit (HCT), tissue plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), mean arterial pressure (MAP), 24 h urine volume (UV), 24 h urine protein (24 hUP), triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A (apoA1), apolipoprotein B (apoB), umbilical arterial S/D ratio (S/D), and amniotic fluid index (AFI) were compared between the two groups before and after treatment. The placenta weight (PW), neonatal weight (NW), 1 min Apgar scoring were compared between the two groups before and after treatment.

RESULTSThere was no difference in DD, Fg, HCT, t-PA, PAI-1, MAP, UV, 24 hUP, TC, TG, HDL-C, LDL-C, apoA1, apoB, S/D, or AFI between the two groups before treatment (P>0.05). In the treatment group PAI-1, Fg, and 24 hUP decreased more after treatment, and they were lower than those of the control group after treatment. The UV and AFI increased and they were higher than those of the control group after treatment with statistical difference shown (P<0.05, P<0.01). In the control group the UV increased and 24 hUP decreased after treatment (P<0.01). There was no improvement in the rest indices (P>0.05). The PW, NW,and 1 min Apgar score > or = 7 were all higher in the treatment group than in the control group, showing statistical difference (P<0.05).

CONCLUSIONCDI was helpful to improve the high condensation state of patients with early onset severe preeclampsia, protect important organs of the mother, and improve the prognosis of neonates.

Objective To analyze the awareness on health among high school students and its influencing factors in Guangdong. Methods Multi-stage sampling and questionnairs "2009 health awareness survey of the Chinese citizens" developed by our Department of Health, were used. Data were analyzed by multivariate multilevel model under MLwinN 2.19 software. Results The mean scores on knowledge and ideas, behaviors and related skills among 1606 high school students of Guangdong province, were 69.08 ± 14.81,60.05 ± 16.85 and 74.99 ± 21.17 respectively. Three items on health showed that they all related to each other and relations between grades (0.972,0.715 and 0.855) were greater than the individuals (0.565,0.426 and 0.438). Conclusion Factors as students from outside the Pearl River Delta region or from the rural areas, being male, at general secondary schools, at grade one, with poor academic performance and more pocket money etc., had lower levels on those related information of health.

OBJECTIVETo compare the differences in the efficacy on distant version of naked eye in the patients of juvenile myopia between rotating manipulation and lifting-thrusting manipulation of acupuncture.

METHODSOne hundred and twenty cases (240 eyes) were randomized into a rotating manipulation group and a lifting-thrusting manipulation group, 60 cases (120 eyes) in each group. Additionally, a corrective lenses group, 60 cases (120 eyes), was set up as the control. In both manipulation groups, Cuanzhu (BL 2),Yuyao (EX-HN 4), Sizhukong (TE 23), Taiyang (EX-HN 5), Fengchi (GB 20), Zusanli (ST 36), Guangming (GB 37) and Sanyinjiao (SP 6) were punctured, but stimulated with rotating manipulation and lifting-thrusting manipulation respectively three times per week, 10 times as a treatment session and totally one session was required. In the corrective lenses group, the glasses were applied at daytime. The clinical efficacy and the changes in distant vision of naked eye before and after treatment were compared among the three groups.

RESULTSThe total effective rate was 87.5% (105/120) in the rotating manipulation group, which was better than 69.2% (83/120) in the lifting-thrusting manipulation group (P < 0.05). The distant vision of naked eye was improved apparently in the rotating manipulation group and the lifting-thrusting manipulation group after treatment (both P < 0.05). But it was not improved in the corrective lenses group (P > 0.05). The distant vision of naked eye was improved more apparently after treatment in the rotating manipulation group as compared with that in the lifting-thrusting manipulation group (0.75 +/- 0.23 vs 0.68 +/- 0.24, P < 0.05). For 96 cases (192 eyes) with acupuncture treatment, in 3-month follow-up, 87.0% (167/192) of the cases maintained the stable vision as the original level and 13.0% (25/192) of them were reduced in the vision In the acupuncture groups, it was found that the improvement of distant vision of naked eye was more obvious after treatment with younger age, better basic vision and shorter duration of sickness (all P < 0.05).

CONCLUSIONAcupuncture achieves the positive and sustainable clinical effect on juvenile myopia, and the results of rotating manipulation are superior to that of lifting-thrusting manipulation. Age, basic vision and duration of sickness impact the clinical efficacy.

OBJECTIVEThe development status of pulmonary artery is one of the most important criteria for decision-making strategy and predicting postoperative outcome in congenital heart disease with decreased pulmonary blood flow. Currently, Nakata index and McGoon index have been used as morphologic index in evaluating the development status of pulmonary artery. Those indices have some shortcoming. It was recently found that pulmonary veins index is a more precise morphological indicator of pulmonary blood flow and development status of pulmonary vessels. This study aimed to explore an index of evaluating pulmonary blood stream and the development of pulmonary vessels, as a criterion for surgical decision-making strategy.

METHODSThe diameters of left and right pulmonary arteries and pulmonary veins were measured on DSA films in 74 patients with congenital heart disease with decreased pulmonary blood flow, The correlative analysis was done between Nakata index, McGoon index, pulmonary vein index (PVI) and postoperative outcome which were the length of stay in ICU, duration of mechanical ventilation and dose of inotropic drugs.

RESULTSExcellent correlations between the size of pulmonary veins and pulmonary arteries were found, the correlation between left pulmonary veins and distal portion of left pulmonary artery was 0.73, between left pulmonary veins and proximal portion of left pulmonary artery was 0.72, right pulmonary veins and distal portion of right pulmonary artery was 0.67, and right pulmonary veins and proximal portion of right pulmonary artery was 0.71. The length of stay in ICU, duration of mechanical ventilation and dose of inotropic drugs correlated well with PVI (r = -0.51, -0.478, and -0.693). Compared with Nakata index and McGoon index, PVI was a better criterion for evaluating the developmental status of the whole pulmonary vessels. In the right ventricular outlet reconstruction patients, the McGoon index for patients with low cardiac output syndrome (LCOS) was 1.36 +/- 0.51, and 1.97 +/- 0.58 for patients without LCOS (t = 2.347, P < 0.05), the Nakata index for patients with LCOS was 164 +/- 106 mm(2)/m(2) and 269 +/- 124 mm(2)/m(2) for patients without LCOS (t = 2.218, P < 0.05), the PVI for patients with LCOS was 152 +/- 77 mm(2)/m(2) and 273 +/- 125 mm(2)/m(2) for patients without LCOS (t = 2.936, P < 0.01), pulmonary vessel index of patients with LCOS was less than that of those without LCOS. When PVI was < or = 180 mm(2)/m(2), postoperative hemodynamics was unstable, the frequency of low cardiac output syndrome and mortality significantly increased.

CONCLUSIONSThe development of pulmonary arteries and pulmonary veins correlated with each other. PVI is a precise morphological indicator of pulmonary blood flow and development of pulmonary vessels. It is a helpful indicator to decide surgical strategy.

In the present experiments, the characteristics of the electrical responses to stimulation of the cerebellum in crucian carp Mauthner cell were explored with microeletrode intracellular recording technique. A composite excitatory postsynaptic potential (cerebellum-evoked EPSP) could be induced from the soma, the ventral dendrite and the proximal end of the lateral dendrite in crucian carp Mauthner cell (M-cell) on either side by stimulation of the ventrolateral region of the cerebellum. The cerebellum-evoked EPSP presented characteristics of relatively short latency (0.63+/-0.09 ms), longer duration (5.49+/-1.13 ms), graded amplitude and dependence on stimulation frequency. Stimulation of the cerebellum with higher intensity always activated the M-cell orthodromically. Multiple intracellular recordings showed that the cerebellum-evoked EPSP originated in the distal end of the ventral dendrite. The results suggest that the cerebellum-M-cell pathway is probably composed of a group of neuron chains with different numbers of synaptic relays projecting to the distal end of the ventral dendrite in order of length of the chains.

OBJECTIVEThe aim of this study was to access the relationship of osteolytic bone metabolic markers such as serum type I collagen carboxy-terminal telopeptide (sICTP), N-terminal cross-linked telopeptides of type I collagen (uNTx), urinary pyridinoline (uPyd) with the therapeutic effect in breast cancer patients with bone metastases.

METHODS120 patients with breast cancer were included in this study. The levels of sICTP, uNTx and uPYD were measured by ELISA assay. The differences were compared between patients with and without bone metastasis. The patients with bone metastasis were treated and followed up as clinically indicated.

RESULTSThe levels of all above mentioned biomarkers in patients with bone metastasis were significantly higher than that in patients without bone metastasis (P < 0.01). A significant correlation was found between each two markers (r > 0.5, P < 0.01). The biomarkers were examined again in 45 patients with bone metastasis after treatment to evaluate the treatment response. The median follow-up was 10 months. Based on clinical evaluation criteria, 25 patients were responders and 20 were non-responders. For responders, after 3 months treatment, the levels of the three bone markers were significantly reduced (P = 0.025, P < 0.001, P < 0.001). But for non-responders, with progression of bone lesions, the levels of the three markers were significantly raised (P = 0.011, P = 0.002, P = 0.002). By means of multiple logistic regression with stepwise selection, the uPyd and uNTx activities were closely correlated with treatment response (OR = 17.0, P = 0.019; OR = 16.7, P = 0.015), however, the sICTP did not show any correlation with treatment response P = 0.841).

CONCLUSIONThe levels of sICTP, uNTx and uPyd may be used as indicators in assessment of the effect of antiresorptive treatment and evaluation of prognosis in breast cancer patient with bone metastases.
