Abstract
Guided by the basic theory of traditional Chinese medicine and using modern scientific methods, Dao-di herbs pharmacology studies the nature, performance, interaction with the body and its clinical application.It is a bridge between the basic research and clinical application of Dao-di herbs. It can objectively describe the law of efficacy of Dao-di herbs, scientifically explain the mechanism of efficacy of Dao-di herbs, explore and establish the standards and methods of Dao-di herbs based on biological effect and clinical efficacy, and provide scientific basis for the special properties, pharmacology and clinical value of Dao-di herbs.Furthermore, we put forward a new idea of building the standard of Dao-di herbs based on the curative effect rather than the origin.The Dao-di herbs standard should come from the systematic research of traditional Dao-di herbs producing areas and form a new characteristic system, through the extraction of environmental, genetic, character, chemical, pharmacological and other characteristics.This standard originates from the tradition, but it is higher than the tradition. It may not have the origin meaning of strict administrative division, but it can better reflect the pharmacological characteristics and excellent clinical value of Dao-di herbs.

Abstract
To establish a fast sensitive, reproducible LC-MS/MS method to study pharmacokinetic properties of THC, and compare relative bioavailability of THC and its solid dispersion in mice. 200 mice were divided randomly into two groups, and administered orally with THC and THC-solid dispersion after fasting (calculate on THC:400 mg x kg(-1)), used HPLC-MS/MS method to determine the THC concentration of each period at the following times: baseline ( predose ), 15, 30, 45 min, 1, 1.5, 2, 3, 4, 6, 24 h after dosing. Calculating the pharmacokinetic parameters according to the C-t curv, and then use the Phoenix WinNonlin software for data analysis. The calibration curves were linear over the range 9.06-972 microg x L(-1) for THC (R2 = 0.999). The limit of detection (LOD) was 0.7 microg x L(-1), respectively. The average extraction recoveries for THC was above 75%, The methodology recoveries were between 79% and 108%. The intra-day and inter-day RSD were less than 13%, the stability test showed that the plasma samples was stable under different conditions (RSD < 15%). The precision, accuracy, recovery and applicability were found to be adequate for pharmacokinetic studies. Pharmacokinetic parameters of THC and THC-solid dispersion orally to mice shows as fllows: T(max), were 60 and 15 min, AUC(0-t) were 44 500.43 and 57 497.81 mg x L(-1) x min, AUC(0-infinity) were 51 226.00 and 68 031.48 mg x L(-1) x min, MRT(0-infinity) were 596.915 6, 661.747 7 min, CL(z)/F were 0.007 809 and 0.005 88 L x min(-1) x kg(-1). Compared with THC, the MRT and t1/2 of the THC-solid dispersion were all slightly extended, the t(max) was significantly reduced, AUC(0-24 h), AUC(0-infinity) and C(max) were all significantly higher, the relative bioavailability of THC-solid dispersion is 1.34 times of THC. The results of the experiment shows that the precision, accuracy, recovery and applicability were found to be adequate for the pharmacokinetic studies. After oral administration to mice, the relative bioavailability of THC-solid dispersion show significant improvement compared to THC.

Abstract
During development inhibitor of DNA-bind-2 (Id2) regulates proliferation and differentiation. Id2 expression has been detected in cancer cells, yet its cellular function and validity as a therapeutic target remains largely unknown. Immunohistochemical analysis of colorectal cancer (CRC) specimens revealed that Id2 was undetectable in normal colonic mucosa, but occurs in 40% of primary tumors and in most CRC liver metastases (P<0.0001). Additionally, Id2 was expressed in all CRC cell lines assayed. CRC cells with reduced Id2 expression demonstrated reduced proliferation. Analysis of CRC cell cycle regulatory proteins showed that reducing Id2 levels reduces cyclin D1 levels and increased p21 levels. Reduction of Id2 expression also enhanced tumor cell apoptosis, increasing levels of the pro-apoptotic protein Bim/Bod, and cleavage of caspase-7 and poly (ADP-ribose) polymerase. In vivo studies show tumors derived from cells with decreased Id2 levels formed smaller tumors with fewer metastases compared with tumors with normal levels (P<0.05). Furthermore, intraperitoneal administration of Id2 small interfering RNA (siRNA) conjugated with the neutral liposome 1,2-dioleoyl-sn-glycero-3-phosphatidylcholine decreased tumor burden in mice compared with control treatment (P=0.006). We conclude that Id2 is upregulated in CRC, and is important in promoting cell survival. In vivo targeting of Id2 by siRNA establishes that it is a valid therapeutic target where its expression occurs.

Abstract
OBJECTIVE To establish scientific and efficient quality control standard of Rhizoma et Radix Notopterygii through two quantitative parameters. METHOD The contents of isoimperatorin and volatile oils in 29 commercial samples from 22 localities of Rhizoma et Radix Notopterygii were determined by HPLC and the method in the pharmacopoeia respectively. The data were statistically analyzed. RESULT Only 3 of 29 samples met the required standard in the Chinese Pharmacopoeia (2005 edition), 87% of samples newly produced in 2005 not met the standard. Statistics showed that the contents of volatile oils and isoimperatorin should reach 1.63% and 0.17% respectively when the samples meet requirement of criterion with more than 80% probability. The contents of volatile oil and isoimperatorin were not significantly different (P < 0.05) in the samples of 2005 and 2003, while the contents of isoimperatorin were significantly different between Notopterygium incisum and N. forbesii samples. CONCLUSION Since the criterion of volatile oils in the Chinese Pharmacopoeia (2005 version) for Rhizoma et Radix Notopterygii is too high to satisfy for most Rhizoma et Radix Notopterygii samples, it is suggested to reduce it to 1.6% (mL x g(-1)). The content of isoimperatorin is proposed to add to the quality standard of Rhizoma et Radix Notopterygii as above 0.2% (mg x g(-1)).

Abstract
To investigate the age-related activity of the epiphyseal plates, a retrospective study of (99m)Tc-methylene diphosphonate bone scans was undertaken. The study comprised 81 males and 46 females aged 2 weeks to 24 years. The total percentage (%) whole-body (ratio of total physis activity to whole-body activity) and the regional % whole-body (ratio of physis activity of one region to whole-body activity) were derived. The ratio of physis activity of one region to the total physis activity was defined as % physis. Before age 12, total physis activity was found to contribute about 10% to whole-body activity. All total and regional % whole-body activities followed sigmoid curves with age. The differences of the parameters (transition centers and widths) suggested that there might be a later and longer period for the disappearance of physis activity in males than in females. For all the regions, % physis changed little with age until after puberty. At age <1, the proportion of bone activity in the body was about 30-35% for skull, 20-25% for lower limbs, and 5-15% for the rest of the regions. The maximal changes during growth occurred in the skull and the lower limbs. The age-related changes of physis activity during growth reflect a combination of the potential of bone to grow and the processes of bone growth and bone turnover. Bone scintigraphy is useful in understanding the changes of physis activity during growth.

Abstract
The importance of herpes simplex viruses (HSV) as human pathogens and the emerging prospect of using mutant derivatives of HSV-1 as potential anti-cancer therapeutics have necessitated a thorough investigation into the molecular basis of host-cell permissiveness to HSV. Here we show that NIH-3T3 cells transformed with the oncogenes v-erbB, activated sos or activated ras become significantly more permissive to HSV-1. Inhibitors of the Ras signalling pathway, such as farnesyl transferase inhibitor 1 and PD98059, effectively suppressed HSV-1 infection of ras-transformed cells. Enhanced permissiveness of the transformed cells was linked to the inhibition of virus-induced activation (phosphorylation) of the double-stranded RNA-activated protein kinase (PKR), thereby allowing viral transcripts to be translated in these cells. An HSV-1-derived oncolytic mutant, R3616, was also found to infect preferentially both transformed cells and PKR-/- (but not PKR+/+) mouse embryo fibroblasts. These observations suggest that HSV-1 specifically targets cells with an activated Ras signalling pathway, and have important ramifications in the use of engineered HSV in cancer therapy, the development of strategies against HSV infections, and the controversial role of HSV in human cancers.

Abstract
An aberrant pancreatic lobe associated with an enteric duplication cyst is a rare cause of relapsing pancreatitis in childhood. We present an 8-year-old boy with relapsing pancreatitis caused by this rare congenital foregut anomaly. The computed tomography (CT) findings revealed an unusually long segment of aberrant pancreatic lobe arising from the pancreatic neck, projecting anteriorly at a distance to a cystic duodenal duplication and appearing as an inflammatory mass. There has been no previous report of this unusual appearance on CT. Appreciation of the relevant anatomy provided by CT led to the successful management of this surgically-treatable cause of relapsing pancreatitis.

Abstract
An unusual case of suprahepatic gallbladder with agenesis of the right lobe of the liver is reported. The anomalous position of the gallbladder was detected by ultrasonography. It was shown to be distended and to contain sludge. The suprahepatic location with agenesis of the right lobe of the liver was preoperatively confirmed by computed tomography. The patient underwent cholecystostomy with drainage and had an uneventful recovery. The postoperative follow-up examinations, including endoscopic retrograde cholangiopancreatography, ultrasonography, arteriography and portography, all added information rarely reported in the literature and helped in the understanding of this uncommon case. Laparoscopic cholecystectomies are widely used but such a procedure was contraindicated in this case because of the ectopic position and inaccessibility of the gallbladder.

Abstract
Chromosomal studies were performed in the same laboratory on 97 untreated cases of de novo acute nonlymphocytic leukemia M2. The overall incidence of chromosomal abnormality was 70.1% (68 out of 97 cases), which was higher in children (84.2%) than in adults (61%). The male to female chromosomal abnormality ratio was nearly the same (male 71% and female 68.4%, P > 0.05). Hypodiploidy was the most common numerical abnormality (39%) and t (8; 21) was the most common structural abnormality (48.1%). In the patients with t(8; 21), 64.5% (20 out of 31 cases) male lost chromosome Y (-Y) and 33% (5 out of 15 cases) female lost one chromosome X (-X).

Southern blot analysis was conducted in 15 patients by using a 1.2 Kb Hind III/Bgl II fragment from the 3' end of the bcr region and a 2.0 Kb Bgl II/Hind III fragment from the 5' end of the bcr as probes. Of the 15 patients in our group, 11 with chronic, myelocytic leukemia (CML), 3 with Ph-negative acute lymphocytic leukemia (ALL), one with myelodysplastic syndrome (MDS). Bcr rearrangements were detected in 9 patients with CML and were negative in the rest of the patients. The results showed that the identification of bcr rearrangement was very important in the diagnosis of Ph-positive leukemias.

Abstract
We studied a 5-year-old boy with mitochondrial myopathy, encephalopathy, lactic acidosis and strokelike episodes that are characteristic of the MELAS syndrome. Results of biochemical, histopathological, and molecular genetic studies from the patient's tissue meet the criteria for diagnosis of mitochondrial disease. An A to G transition at the 3243th nucleotide position of mitochondrial DNA (mtDNA) was found in the blood cells and hair follicles, instead of in muscle, from the propositus. To the best of our knowledge, this is the first reported MELAS case associated with mtDNA mutation in blood cells and hair follicles, instead of in the target muscle tissue, that has ever been documented in Taiwan. Brain lesions demonstrated by angiography, computed tomography (CT) and magnetic resonance imaging (MRI) are discussed.

Abstract
Clinical and prognostic investigations were conducted in 46 cases of M2/t(8;21) leukemia and 29 cases of M2/NN patients. Results showed that most patients with M2/t(8;21) were young males with higher incidence of extramedullary infiltrations. Complete remission rate was higher but with earlier relapse. The prognosis of patients with M2/t(8;21) with loss of one sexual chromosome was poor.

Abstract
The bcr/abl fusion gene in 20 patients with chronic myeloid leukemia (CML) was detected by RNA polymerase chain reaction, which used mRNA as the starting material to generate cDNA with reverse transcriptase followed by PCR amplification (RNA/PCR). Amplification of a sequence spanning the bcr/abl junction region was achieved by using peripheral blood cells as the source of mRNA from all 20 patients with CML, including 3 cases of Ph (-) CML, and cell line K562 was derived from patients with CML. No amplification was seen when mononuclear cells from 3 normal individuals, 2 patients with lymphoma and cell line HL-60 were used. The presence or absence of bcr exon 3 in the fusion mRNA was determined by the size of the amplified fragments. Of the 20 CML patients, 15 showed only the 165-bp amplified band (indicating retention of bcr exon 3), one showed only the 90-bp amplified band, and 4 showed both 165-bp and 90-bp bands. Both bands were seen more frequently in blast crisis than in remission and chronic phase.

Abstract
Nine patients with chronic myelocytic leukemia (CML) and 1 patient with erythroleukemia were studied with 3'bcr and 5'bcr probes using Southern blot hybridization technique. Bcr rearrangements were detected in 8 patients with CML in the chronic phase, and bcr rearrangement was deduced to have existed in a CML patient in blastic crisis. However, no abnormal fragment was found in the patient with erythroleukemia. 3'bcr and 5'bcr probes combined with proper restriction enzymes were believed to be of great value in determining bcr rearrangements in Ph positive CML.

Abstract
Pokeweed antiviral protein (PAP-s) was prepared from seeds of Phytolacca americana. Monoclonal antibody against human pan-T lymphocyte Wu71 was linked to PAP-s by a disulfide bond. The results of SDS-PAGE, double immunodiffusion of active monoclonal antibody and PAP-s showed that the conjugate was highly cytotoxic to the human T-leukemic cell line CEM, but not to antigen-negative cell line SP2/O. At a concentration of 10(-9) mol/L, 76.4% of the target cells were killed, as compared with 10.1% at 10(-9) mol/L of free PAP-s. Treatment of the CEM cells with conjugate at 10(-9) mol/L reduced their rate of protein synthesis by 72.4%, as determined with 14C-leucine incorporation. The immunotoxin may be useful for the in-vitro eradication of leukemic cells in autologous bone marrow transplantation to leukemia patients.

Abstract
During 1987-1988 cytogenetic studies were performed in 30 patients with acute lymphoblastic leukemia (ALL). Of the 30 patients 15 (10 children and 5 adults) were found to have abnormal karyotypes including 8 cases (27%) of pseudodiploidy, 2 cases (7%) of hypodiploidy, one case (3%) of low-hyperdiploidy (modal number 47-50), and 4 cases (13%) of high-hyperdiploidy (modal number greater than 50). Immunological classification was performed by using monoclonal antibodies in 26 patients, and the most common immunophenotype was C-ALL. The patients with abnormal karyotypes were more likely to be NuLL-ALL (6 in 14) as compared with patients with normal karyotype (1 in 12). In our series, there was no significant difference between the patients with and without cytogenetic changes in regard of clinical findings such as FAB classification, the rate of complete remission, percentage of lymphoblasts in bone marrow cells and blood picture.

Abstract
Karyotypes and in vitro cultures of bone marrow cells from eleven patients with acute myelogenous leukemia M2 type were performed. 8/21 translocation was found in 5 patients. In all of them the cultures in vitro shared one characteristic, i.e., clusters were small and less in number. These patients could relatively easily obtain complete remission. The similarity of CFU-GM in patients with t (8; 21) may be another important biological phenotype.

Abstract
The complete DNA sequence (1369 bp) of an EcoRI-1.35-kb repeated element (ER-1) of the mouse BamHI family has been determined. Analysis of this sequence revealed that a portion of the 3' end (positions 1277-1369) of ER-1 was found to share 91% homology with the flanking cellular sequence between two adjacent intracisternal A-particle (IAP) genes, IAP-19A and IAP-19B.
