Six taxane diterpenoids were isolated from the stem bark of Tax us cuspidata Sieb. et Zucc.. On the basis of physical and chemical properties and spectra analysis,they were identified as 2'-de sacetoxyaustrospicatine(Ⅰ). taxol(Ⅱ),cephalomannine (Ⅲ), 2-deacetoxyl taxinine J (Ⅳ),taxinine B(Ⅴ) and 10-deacetyl-7-0-?-Dxylosyl-taxol (Ⅵ).

Objective To observe the effect of adjusting high dietary profein intake on nutritional status of peritoneal dialysis (PD) patients. Method Thirty three PD patients whose daily protein intake (DPI) was over 1.2g/(kg? d) were included in study from July, 2005 to November, 2006. A recipe was given by a professional dietitian for every patient to reduce DPI meanwhile maintaining sufficient daily energy intake (DEI). DPI, DEI, serum albumin (ALB), lean body mass(LBM) and subjective global assessment(SGA) and the prevalence of hyperphosphatemia, hyperkalemia and metabolic acidosis were evaluated before and after 3 and 6 mo adjustment. Results At the end of observation, 28 patients were enrolled in the study. Their mean age was 61.37?12.25 yrs, 11 males and 17 females with dialysis period 8.8 mon (1～66 mo). DPI and DEI were significantly decreased during 6 mo (P=0.000). Nobody complained about gastrointestinal symptoms, and the quality and satisfaction of life during the study were not significantly different. Serum Alb at 3 rd month was higher than the start of study (36.22?2.79g/L vs 37.34?3.32 g/L,P

Objective To study the relationship between the cerebrospinal fluid (CSF) volume and intracranial measurement line in normal Chinese by useing CT data and computer technology.Methods By CT scan,to measure CSF volume and third ventricle maximum width,suprasellar cistern minimus width,lateral ventricle width in hypothalamic layer,caudate nucleus pitch and other index by age and gender in 178 normal adults.Results There were significant difference between male and female CSF volume in the groups of 14-20 years(23 cases),31-40 years(33 cases),41-50 years(32 cases) and ＞ 60 years (13 cases)(P＜ 0.05 or ＜ 0.01).The CSF volume between male and female had significant difference (t =3.302,P =0.001).The CSF volume and third ventricle maximum width had significant correlation (r =0.685).Conclusion The third ventricle maximum width is the most closely with CSF volume.

Objective To discuss the medication principles of diagnosis and treatment for insomnia from spleen and stomach; To provide references for clinical treatment for insomnia.Methods Relevant articles about diagnosis and treatment forinsomnia from spleen and stomach were searched in CNKI and Wanfang Data through computers, the data were input into Traditional Chinese Medicine Inheritance Supporting System (V2.5) and then association rules, apriori arithmetic, improved mutual information method, and complex system entropy cluster methods were used to analyze the medication principles of diagnosis and treatment for insomnia from spleen and stomach. Results Through screening, totally 87 prescriptions were included, involving 165 herbal medicine. Data mining results showed that there were 30 high-frequency herbal medicine, 19 high-frequency medicinal combinations, and 4 medicinal association rules. Evolution led to 13 medicinal combinations of 2 herbal medicine and 3 new prescriptions. Conclusion The main method of diagnosis and treatment for insomnia from the spleen and stomach is regulating qi activity of spleen and stomach. The features of common medicine are invigorating spleen to reduce phlegm, clearing stomach and calming the adverse-rising energy, and tonifying qi and soothing nerves, which can offer references for clinical treatment for insomnia.

Objective To clarify the clinical features of solid pseudo-papillary tumor of pancreas. Methods Clinical data of 38 patients with solid pseudo-papillary tumor of pancreas were analyzed retrospectively. Results The clinical manifestations included a palpable abdominal mass, abdominal pain and discomfort. Tumor occured in 1 case younger than 10 years old, 11 cases between 11 years old and 20 years old, 7 cases between 21 years old and 30 years old, 9 cases between 31 years old and 40 years old, 5 cases between 41 years old and 50 years old and 1 case older than 50 years. Immunohistochemistry staining showed CgA( + ) in 6 cases,Vim( + )in 29 cases,AAT( + ) in 29 cases,Syn( + ) in 21cases,CD10( + ) in 34 cases,CD56( + ) in 37 cases, Ki-67 ( + ) in 36 cases and PR( + ) in 38 cases. Conclusion Solid pseudo-papillary tumor of pancreas is closely associated with gonadal hormone and reproductive system.

"Congbai", fistular onion bulb, a Chinese herbal drug, was systematically studied in such aspects as botanical morphology, macroscopical characters, histology and so on. Scientific basis was provided to draw up the standard of identifying "Congbai".

2?l 10% ricin were injected into the pelvic nerve of cats. After 3～5 survival days 20% HRP solution was injected into the ipsilateral lateral parabrachial nucleus, 2～3 days later the animals were perfused with paraformaldehyde and glutaraldehyde, the brain and spinal cord were removed and processed for light and electron microscopy. It was confirmed that the primary afferent terminals (degenerated) of pelvic nerve formed axo-dendritic and axo-somatic synapses with the retrograde labelled neurons projected to the lateral parabrachial nucleus which were located in the dorsal commissure nucleus (DCN), intermediolateral nucleus (IML) and lamina Ⅰ of sacral spinal cord. Hence, the secondary afferent pathway of pelvic visceral sensation, as. indicated at the ultrastructural level, might originate from DCN, IML and lamina Ⅰ of sacral spinal cord and project to the lateral parabrachial nucleus.

The Nissl and Golgi staining methods and electron microscopy were u(?)o investigate the architecture of dorsal commissure nucleus (DCN) of the sacral spinal cord in cat. A morphologically specific nucleus could be identified in the medial part of the lamina Ⅵ of dorsal horn. The nucleus located beside the dorsal funiculus at the lumbar level and gradually moved toward the midline of the dorsal gray commissure in the ventromedial direction as the dorsal gray commissure enlarged at the segments S_(1-2) and two ellipsoid nuclei was formed at the two sides of the midline. A large triangular nucleus was gradually formed by fusion of the two nuclei at S_3-Co_1. Golgi stain positive neurons could be classified into three types: (1) small-triangular neurons (60%); (2) fusiform neurons (30%); (3) oval and irregular neurons (10%). The cell organells of most neurons were plentiful. The cell nucleus was irregular and often with deep invaginations. A large number of free ribosomes and saccules could be found in the canals formed by the nuclear invagination. There were axo-dentritic, axo-axonic, axo-somatic synaptic contacts in the DCN with percentages of 89%, 6%, and 5% respectively. The serial synapse, axo-spinous synapse and crest synapses could also be found.

Objective: To study the effects of light intensity on the compressive strength and tensile strength of light -curing composite resin. Methods: 25 samples of Shade A (Dentsply,USA) light-curing composite resion in the size of 10?5?1(mm) and equally divided into 5 groups.The light intensities (mW/cm 2?40 s) of 300,500,800,300 mW/cm 2?10 s+500 mW/cm 2?30 s,300 mW/cm 2?10 s+800 mW/cm?30 s were applied during the light-curing in group 1,2,3,4 and 5 respectively.The compressive strength and tensile strength of of the samples were measured by computer-controlled electronic testing machine (type WDW-100). Results:The compressive strengths (MPa) of group 1,2,3,4 and 5 were 228.68?20.25,274.67?6.99,380.53?9.81,345.47?10.71 and 414.06?29.34 respectively (P
