METHODAccording to over 10 years accumulated experience and be keenly aware of the author, the evaluation method of standardized processing technology and Chinese pieces quality, aimed at consummated the standard material of the quality evaluation of Chinese herbal pieces at the current situation, and inaccordance with the need of improving quality standard system of Chinese herbal pieces, illustrate the necessity of accelerating basic research of Chinese standard pieces as standard materials; from the technical specification for collecting and processing of raw materials, and the technical specification, homogenized sample, packaging, storage and etc., for processing of candidate standard pieces, determine the methods and steps of technical specifications for standard pieces as the standard substance, determine the methods and steps of technical specifications for standard pieces as the standard substance.

RESULT AND CONCLUSIONTo speed up the basic research of standard of Chinese medicine pieces as of standard material is very necessary. The research objective is to specificate the processing technical for a number of standard pieces, to identify technical specifications and to ascertain the guiding principle and technical specification of decoction pieces as standard substance. This research will provide basic scientific data relevant national departments to apply for the accreditation of the standard substance.

AIM: To evaluate the effects of simulated acute ischemia and reperfusion on L-type calcium current (ICa,L) in ventricular myocytes from diabetic and non-diabetic rabbits.METHODS: Using whole-cell patch clamp techniques, ICa,L was measured in left ventricular myocytes isolated from 6-week alloxan-induced diabetic rabbits and age-matched control ones at baseline, 5 min of simulated ischemia, and 5 min of reperfusion.RESULTS: There were no significant differences on baseline maximum ICa,L densities between diabetic and control ventricular myocytes. In control cells (n=11), maximal ICa,L densities of baseline, ischemia and reperfusion were (-8.36±1.63)pA/pF, (-5.90±1.75)pA/pF and (-4.22±1.02)pA/pF, respectively. The ICa,L of ischemia was less than that of baseline (P<0.01), while the ICa,L of reperfusion was less than those of baseline (P<0.01) and ischemia (P<0.05). In diabetic cells (n=9),the ICa,L of baseline, ischemia and reperfusion were (-7.55±1.62)pA/pF, (-6.05±1.58)pA/pF and (-5.12±1.13)pA/pF, respectively. Only ICa,L of reperfusion was less than that of baseline (P<0.01), while ICa,L of ischemia was not significantly different from that of baseline (P>0.05) or reperfusion (P>0.05).CONCLUSION: ICa,L in diabetic ventricular myocytes represents blunted response to acute ischemic injury, being decreased more slowly than that in control cells. Post-ischemic reperfusion is still a potent inhibitor against ICa,L in both diabetic and non-diabetic cells. This study may be indicative of the mechanism about ischemia-reperfusion injury to diabetic myocardium and the therapy for diabetic patients with ischemic heart disease.

The aim of the study was to explore the safety management strategies for homeless persons with psychotic disorders.The following nursing management measures were implemented in 127 psychiatric patients,including precaution of aggression and other accidents,treatment of physical diseases,prevention and control of infectious diseases,intensive managementof key areas,key time and key patients,formulation and implementation of safety management regulations and emergency response system,nurse training on professional diathesis,skills and safety awareness.These measures effectively avoided the risksin psychiatric nursing,reduced nursing errors and ensured patient safety.

Recurrent miscarriage is a common disease in clinical obstetrics and gynecology. There is no curative treatment for recurrent miscarriage in conventional medicine. Traditional Chinese medicine (TCM) has been widely used in the treatment of recurrent miscarriage in China for thousands of years. However, randomized controlled trials (RCTs) with high quality evaluating the effectiveness and safety of Chinese herbal medicine (CHM) still lack. This study was conducted in order to identify methodological problems in published or unpublished RCTs of CHM in the treatment of recurrent miscarriage, and provide suggestions for TCM researchers to conduct high-quality clinical research.

Objective To explore perinatal risk factors associated with the neurobehavioral development of small for gestational age (SGA) full-term neonates.Methods This prospective cross-sectional study included 111 full-term newborn infants from Apr 2008 to Apr 2010 born in Yan-tai Yuhuangding Hospital.Detailed clinical data in perinatal period of all subjects were recorded.Infants aged 3 ～ 7 days were assessed with neonatal behavioral neurological assessment (NBNA) for neurobehavioral development.Logistic regression analysis was used to explore risk factors associated with the score of NBNA.Results Significant differences (P ＜ 0.05) were found between full-term SGA (10.72 ± 1.41,7.13 ± 0.96,7.32 ± 0.74,37.16 ±1.32) and normal neonates (11.27 ± 1.04,7.89 ± 0.72,7.62 ± 0.64,39.12 ± 0.76) in terms of capacity,active and passive muscle tension and NBNA score.Full-term SGA neonates had lower score than control.Univariate logistic regression showed that delivery,placenta abnormalities,umbilical cord abnormalities,infection in perinatal period,gestational hypertension,twin pregnancy,hyperbilirubinemia affected neurobehavioral development of full-term SGA infants.Multivariate logistic regression showed that mothers' infection in perinatal period (OR =2.175,95 ％ CI 1.981 ～ 2.408,P ＜ 0.05),twin pregnancy (OR =1.936,95％ CI 1.517 ～2.368,P ＜ 0.05) and hyperbilirubinemia (OR =1.518,95％ CI 1.072-2.149,P ＜ 0.05) were risk factors for neurobehavioral delay of full-term SGA infants.Conclusion Full-term SGA neonates showed poorer quality in neurobehavior.Risk factors associated with neurobehavior of full-term SGA infants included mothers' infection in perinatal period,twin pregnancy and hyperbilirubinemia.

It was show that the 3 medical preparations, viz: Chuanxiong, the mixture of Chuanxiong & Ginseng ( CG Mixture ) , and the mixture of Chuanxiong & Miltiorrhizae could increase the coronary retrograde flow & decrease the resistance to collateral flow. The CG mixture exhibited positive effects on cardiac output, coronary flow blood, & retrograde pressure, but the other 2 medicines showed negative effects.These findings suggest that the CG mixture could improve & regulate the cardiovascular function, open the collateral vessels to reduce the ischemic size, while the other 2 medicines might reduce the cardiac power consumption. It is expected that the CG mixture may be more suitable for treatment of coronary diseases with cardiac insufficiency & hypotension, and the other 2 may be used for that with hypertension.

These groups of Chinese medicines were prepared-Cbuanxiong, a mixture of Chuanxiong & Ginseng, & a mixture of Chuanxiong & Miltorrhiza. The effects of these groups of drug on sischemic areas ( subepicar-dial ) and ( subendocardial) PO2 were compared in anaesthetized open-chest mongrel dogs. The heart tissue P02 was determined simultaneously at a depth of 2-3mm(epicardial) and 8-9mm (endocardial) 晈ith small platinum electrodes by polarography. The 3 combinations of medicine could not only increase the heart tissue PO2 in both areas when ischemia occured, but also increase deep area P02 to a greater extant than superficial area PO2. Lignsticum Chuanxiong and Panax Ginseng were more effective than the other 2 groups.

Objective To study the expression, distribution and significance of C2 gene in hepatocellular carcinoma (HCC) and gastric cancer tissue. Methods ABC immunohistochemical method was used to detect the expression of C2 protein in 60 samples of HCC tissue and 58 samples of gastric cancer tissue, and Western blot technique was used to detect the expression of C2 protein in 10 samples of HCC tissue and pericancerous tissue. Results 1. Expression of C2 protein in HCC tissue: in 60 samples of HCC and 42 samples of pericancerous tissue, the positivity rate of C2 protein was 27.3% and 83.3%, respectively. The positivity rate of C2 protein was significantly higher in pericancerous tissue than that in HCC tissue ( P

X-ray plane film. Three-dimensional CT could show the three-dimensional structure of spinal canal clearly. The postoperative efficacy of all patients was satisfactory. Conclusion The three checking methods of spinal fracture were complementary to each other, but three-dimensional CT had the advantage in reconstructing spinal canal.
