Objective To investigate the relationship between serum leptin(LP) level and glycometabolism in pregnancy with abnormal glucose challenge test(GCT) and the corresponding outcome of pregnancy. Methods Serum LP level,fasting serum insulin(FINS) and fasting blood glucose(FBG) levels were measured by radioimmunoassay in 23 patients with abnormal GCT but normal oral glucose tolerance test(OGTT),20 with impaired glucose tolerance(IGT),20 with gestational diabetes mellitus(GDM)(studied groups above) and 30 normal pregnant women(control group).LP,FINS,FBG, insulin resistance index(HOMA-IR) and ?-cell function index(HOMA-IS) were compared among the groups and the outcomes of pregnancy were observed. Results ①There were significant differences in LP,FINS,FBG,HOMA-IR and HOMA-IS between the studied groups and the control group(P0.05).③There were signi-ficant differences in the gestational weeks of delivery,cesarean section rate and neonatal weight between the studied groups and the control group(P0.05). Conclusion Both insulin secretion and insulin resistance are elevated in pregnancy with abnormal glycometabolism,and are closely correlated to the increased serum level of LP.There existed abnormal glycometabolism in patients with abnormal GCT but normal OGTT,which is correlated to the outcome of pregnancy.

Most Chinese medicine has good clinical efficacy and application. However, the material basis is vague for the lack of basic research, the value of Chinese medicine is hard to reflect for the low technology level and product quality is difficult to maintain for the quality control indicator selection is incorrect. Chinese medicine Jinfukang oral liquid is a typical product of Chinese medicines. Jinfukang oral liquid was selected as a model drug in this article. Based on the overall concept and systems theory of traditional Chinese medicine, the research idea and technology system for modern Chinese medicine secondary exploitation was formed. The system includes three parts, for the first, basic research to make clear the components structure and their action mechanism, for the second, technology upgraded to optimize process and improve the product quality, for the last, exploring the associated industry to form the industrial chain. The research ideas and technology system based on the material basis research and development of modern Chinese medicine, guided with component structure in Chinese medicine and aimed clinical needs. This research ideas and technology system provides strategies and methods for the development of modern Chinese medicine secondary exploitation.

Objective To determine the utility of diffusion-weighted magnetic resonance imaging ( MR DWI ) in detecting tumor necrosis with histological correlation after neoacljuvant chemotherapy. Methods Conventional MRI and DWI were obtained from 36 patients with histological proven esteosarcoma. Magnetic resonance examinations were performed in all patients before and after 4 cycles of preoperative neoadjuvant chemotherapy. Apparent diffusion coefficients (ADC) were calculated. The degree of tumor necrosis was assessed using the histological Huvos classification after chemotherapy. T-test was performed for testing changes in ADC value between the 2 groups. P value less than 0. 05 were considered as a statistically significant difference. Results The differences in ADC between viable [ (1.06±0. 30) ×10-3mm2/s ] and necrotic [ (2. 39±0. 44 )×10-3mm2/s] tumor were significant (t= 3. 515,P<0. 05). Changes in ADC value was greater in good responses to neoadjuvant chemotherapy than in poor responses, the ADC value in good responses was increased from (1.18±0. 19)×10-3mm2/s to (2. 27±0. 20)×10-3mm2/s, the corresponding value in poor responses was increased from (1.45± 0.11)×10-3mm2/s to (1.83±0. 16)×10-3mm2/s, There was significant difference in changes of ADC values between good responses and poor responses ( t = 4. 981, P < 0. 01 ). Conclusion Diffusion-weighted MRI permits recognition of tumor necrosis induced by chemotherapy in osteosarcoma. DWI is correlated directly with tumor necrosis. They have potential utility in evaluating the preoperative chemotherapy response in patients with primary osteosarcoma.

Objective: To analyze the clinical features and outcomes of cardiac resynchronization therapy (CRT) in patients with dilated-phase hypertrophic cardiomyopathy (DHCM). Methods: A total of 16 DHCM patients received CRT in our hospital from 2007-03 to 2016-01 were retrospectively studied to analyze their clinical features and outcomes. Results: There were 12 male and 4 female patients at the mean age of (53.3±13.5) years. Pre-operative QRS duration of ECG was (158.7±32.2) ms, left ventricular ejection fraction (LVEF) was (33.6±6.3) %, the patient with NYHA class I, II, III and IV were 1, 5, 8 and 2 respectively. 13 patients received new CRT device, 3 received upgraded device and 8 (50%) combining atrial fibrillation (AF). The patients were followed-up for (2.56±2.13) years, 5 of them died including 3 of heart failure, 1 of sudden death and 1 of stroke. At 6 months follow-up time, 7 patients had the response to CRT which was defined by the improvement of NYHA class≥1 and the absolute elevation of LVEF≥5%; NYHA class improved from (2.69±0.79) to (2.38±0.89), P=0.02; LVEF increased from (33.6±6.3) % to (40.03±9.83) %, P=0.01. Conclusion: DHCM patients with CRT indication had the higher incidence to suffer from AF, those were more in patients with traditional pacemaker or ICD upgrading. DHCM patients with CRT had the poor general prognosis, while there was still certain proportion of patients had the response to CRT.

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.

AIMTo evaluate the effects of administration of hyperbaric oxygenation(HBO) when initiated at different time after acute transient ischemia. Apoptosis in the ischemic penumbra was further investigated to search for the possible mechanism.

METHODSThe male SD rats were randomly assigned to the following groups: control, HBO therapy initiated 3 h after ischemia, HBO therapy initiated 6 h after ischemia, HBO therapy initiated 12 h after ischemia. All animals were subjected to 90 min intraluminal middle cerebral artery occlusion (MCAO) with the regional cerebral blood flow monitored in vivo by laser Doppler flowmetry. HBO treatment was performed in a pressure chamber with 100% O2, 3 arm for 1 h. Neurological deficits and infarct volumes were assessed at 24 hours after ischemia. The immunohistochemical changes of apoptosis in the penumbra were evaluated by detecting the expression of cleaved Caspase-3, cleaved Caspase-9, Bcl-2, Bax and TUNEL staining.

RESULTSHBO therapy initiated at 3 and 6 hours after ischemia significantly improved the neurological function and reduced infarct volume. Meanwhile, it increased the expression of Bcl-2 protein and decreased the expression of activated Caspase-3, activated Caspase-9 and TUNEL-positive cells. However, HBO therapy administrated 12 hours after ischemia aggravated the neurological deficits and enlarged infarct volume, while it showed no significant reduction of apoptotic change compared with control.

CONCLUSIONThere is a therapeutic window for the use of HBO in acute transient cerebral ischemia in rats. HBO-treatment is highly effective in reducing infarct volume when initiated up to 6h after the onset of ischemia. Inhibition of apoptotic cell death in the penumbra appears to be the underlying protective effect of early therapy.
