OBJECTIVETo explore effects of Tongxinluo Capsule (TC) on platelet activating factor (PAF), vascular endothelial function, thrombolysis in myocardial infarction (TIMI) blood flow, and heart function in acute myocardial infarction (AMI) patients after delayed percutaneous coronary intervention (PCI).

METHODSTotally 80 AMI inpatients were recruited at Department of Cardiology, People's Hospital of Jiangxi Province, from Jan. 2008 to Sep.2013. Those in line with inclusion criteria were randomly assigned to TC treatment group and the conventional treatment group by random digit table, 40 in each group. Besides, another 40 healthy subjects from examinees at Outpatient Department were recruited as a healthy control group. PCI was performed after 1-week treatment. Then blood samples were collected, and then blood contents of CD62P, CD63, GP II b/III a, ET-1, NO, and plasma von Willebrand factor (vWF) levels were detected. Coronary TIMI blood flow and corrected TIMI frame count (CTFC) were determined during PCI. Meanwhile, noninvasive blood pressure (BP) and heart rate (HR) were recorded before and after PCI, and cardiac function measured. They were compared with the healty control group.

RESULTSCompared with the healthy control group, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, and ET-1 significantly increased, but NO significantly decreased in AMI patients (all P < 0.05). After 1-week intervention of TC, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, NO, and ET-1 significantly decreased (P < 0.05, P < 0.01). Compared with the conventional treatment group at the same time point, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, and ET-1 decreased more significantly in the TC group (P < 0.05, P < 0.01), increased NO levels were also more obviously seen (P < 0.01). The aforesaid parameters changed more obviously at day 30, as compared with those changes at week 1 (P < 0.05, P < 0.01). The TIMI blood flow grade and CTFC were more obviously improved after PCI in the two treatment groups. Better TIMI blood flow was seen in the TC group. TIMI level 3 blood flow rate was higher in the TC group than in the conventional treatment group with statistical difference (P < 0.05). The left ventricular ejective factor (LVEF) after PCI was obviously elevated in the TC group and the conventional treatment group (P < 0.01), and the improvement was more obviously seen in the TC group (P < 0.05). There were 6 cases of recurrent angina, 3 cases of ventricular tachycardial (VT)/ventricular fibrillation (VF), 6 cases of heart failure (HF), 1 case of cardiac sudden death in the conventional treatment group, with the total incidence of cardiovascular events being 40% (16/40). There were 2 cases of recurrent angina, 2 cases of VT/VF, 2 cases of HF, no cardiac sudden death in the TC treatment group, with the total incidence of cardiovascular events being 15% (6/40). There was statistical difference in the recurrent rate of cardiovascular events between the two groups (χ² = 2.27, P < 0.05).

CONCLUSIONTC not only could prevent coronary embolism of AMI patients after delayed PCI, attenuate vascular endothelial injury, but also could improve TIMI blood flow, and strengthen cardiac systolic function.

OBJECTIVE:To optimize the matrix formulation and preparation technological parameters of Compound Bingjia Cream. METHODS:To prepare water phase and oil phase matrix solutions respectively,and then the former was added into the lat-ter and well mixed together. The matrix formulation was optimized with the overall scores of appearance,high temperature,low temperature and oil and water stratification after centrifugal test as the evaluated indexes. High performance liquid chromatography was used to determine the content of metronidazole. Gas chromatography was adopted to determine the content of borneol. With the matrix temperature at the time of adding the main drug mixture,matrix quantity,emulsification method and emulsification time as observed factors,and the overall scores of metronidazole content,borneol content and the overall scores of preparation(the overall scores of appearance and stability tests) as the observed indexes,L9(34) orthogonal test was designed to optimize the preparation technological parameters of Compound Bingjia cream and verification for technology was conducted. RESULTS:The optimal oil phase matrix formulation was as follows as cetanol of 10 g,glyceryl monostearate of 16 g,stearic acid of 20 g,albolene of 8 g, while the optimal water oil matrix formulation as triethanolamine of 2 g,glycerinum of 24 g. The optimal preparation technological parameters were the matrix temperature of 50℃at the time of adding the main drug mixture,matrix of 300 g,emulsification meth-od of colloid emulsification,emulsification time of 30 min,where metronidazole content was 1.83%,borneol content 2.88%. The results of 3 verification tests showed the overall scores were all 25,with metronidazole content of 2.1%,2.1%,2.2%(RSD=2.71%,n=3),borneol content of 3.2%,3.3%,3.1%(RSD=3.12%,n=3). CONCLUSIONS:The optimal matrix formulation and technological parameters of the preparation are stable and feasible,and suitable for mass production.

Objective To study the life quality of 2 - 3 years old survivors in Neonatal Intensive Care Unit (NICU). Methods Severe neonates were randomly assigned to intervention group (group 1,30 cases) and non- intervention group (group 2,30 cases) depending on the early intervention applied or not,as well as 30 healthy newborns as normal controls. The physical,neurological conditions and intelligence test were taken regularly. To investigate the psychological state, actions, temperament and family conditions when they were2-3 years old.Results Mental development index(MDI) and physical development index(PDI) in early interventional group were significant higher than those in group 2(P

OBJECTIVE: To investigate the pathological factors of syndrome pathomechanism through studying the correlation between syndromes of posthepatitic cirrhosis and biological parameters. METHODS: Clinical information of three hundred and fifty-five patients with posthepatitic cirrhosis was collected and the database was established. Parameters with statistical significance were analyzed with multi-factor regression analysis to investigate the main influencing factors of the syndromes of posthepatitic cirrhosis. RESULTS: Formulae of six syndromes, including syndrome of yin deficiency of liver and kidney, syndrome of damp heat, syndrome of stagnated heat smoldering, syndrome of yang deficiency of spleen and kidney, syndrome of stagnation of liver qi and spleen deficiency and syndrome of blood stasis due to qi deficiency, were established with stepwise regression analysis. CONCLUSIONS: One of the pathophysiological bases of syndrome of blood stasis due to qi deficiency in cirrhosis is synthetic dysfunction of hepatocytes. The pathophysiological basis of syndrome of damp heat is inflammatory injury, which is also syndrome of stagnated heat smoldering in cirrhosis patients. The relationship between syndrome of yin deficiency of liver and kidney and stasis and damp heat may be the pathophysiological basis of the posthepatitic cirrhosis..

A sequential extraction procedure has been proposed for the evaluation of the speciation of heavy metals including Cd,Cu,Pb and Zn in sediments from mariculture area,and the speciation of heavy metals was separated and defined as acid soluble fraction,reducible fraction,fraction bound organic matter,fraction bound sulfides and residual fraction. Matrix effects of high salinity on the determination of heavy metals in sediments were eliminated by matrix matching and internal standard methods when inductively couple plasma optical emission spectroscopy (ICP-OES) and mass spectroscopy (ICP-MS) were used,respectively. The results showed that the measured values of marine sediment reference materials were consistent with the standard values when the digestion solutions were determined after dilution. The extraction results of the prepositional extraction procedure and European Community Bureau of Reference Program (BCR) procedure were compared and the selectivity of extractants was investigated. The preliminary studies indicated that this sequential extraction procedure was applicable for evaluating the speciation of heavy metals in sediment with organic substances pollution and eutrophication,especially for fraction bound organic matter and fraction bound sulfides.
