OBJECTIVETo explore the effects of arecoline on hepatic insulin resistance in type 2 diabetes rats and to elucidate its possible mechanism.
METHODSForty five Wistar rats were fed with high fructose diet for 12 weeks to induce type 2 diabetic rat model. rats were randomly divided into 5 groups (n = 8): control group, model group and model group were treated with different dose (0, 0.5, 1, 5 mg/kg) of arecoline. After 4 weeks, the fasting blood glucose, blood lipid and insulin level measured , mRNA expression of liver constitutive androstane receptor (CAR), pregnane X receptor (PXR), glucose-6-phosphatase (G6Pase), phosphoenolpyruvate carboxykinase (PEPCK), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were detected by reverse transcription polymerase chain reaction (RT-PCR), the protein expression of p-AKT and glucose transporter4 (GLUT4) were detected by Western blot.
RESULTS1.5 mg/kg arecoline could significantly decrease the level of fasting blood glucose, blood lipid, blood insulin level and liver G6Pase, PEPCK, IL-6, TNF-alpha mRNA level in type 2 diabetes rats. 1.5 mg/kg arecoline also could significantly increase CAR, PXR mRNA level and p-AKT and GLUT4 protein expression.
CONCLUSIONArecoline improved hepatic insulin resistance in type 2 diabetes rats by increasing the mRNA levels of CAR and PXR leading to the creased glucose metabolism and inflammation related genes expression.

OBJECTIVE:
To study the morphological characteristics of femurs of adult human and 11 kinds of adult animals from cattle, horses, pigs, goats, sheep, dogs, cats, rabbits, geese, ducks, chickens, and to establish an effective species identification method among various species.
METHODS:
The 4 cm mid-diaphyseal segment of the femur from adult human (older than 20 years old) at autopsy was obtained. Addi-tionally, the 4 cm ones from 11 kinds of adult animals were obtained. After decalcification, all femurs were made into slices, and then were observed by optical microscope. The 25 indexes were selected and analyzed by step discriminant analysis according to differences between human and mammal, human and poultry, and human and 11 kinds of animals.
RESULTS:
The histological structure of bone mineral density of middle part of femur had obvious characteristics among the species. And the morphology and number of osteon showed the trend of obvious biological evolution. There were 11 indexes with significant differences between human and 11 kinds of animals to establish some mathematical models to discriminate all species. The correct discrimination rate was 96.3% between human and mammal. The correct discrimination rate was up to 100% between human and poultry, and was 89.4% among human, mammal and poultry.
CONCLUSION
The mathematical models have good correct discrimination rate among human and the other animals, which could be applied in the practical species identification cases.

OBJECTIVETo observe the distribution of the nerve fibers in the bone tissue and the entry points of these fibers into the bone.
METHODSThe adult tibia was used for the ground sections which were afterwards made into the slice sections by decalcification in ethylenediamine tetraacetic acid (EDTA). The ground sections were stained in silver and the slice sections were stained in silver and haematoxylin and eosin (HE) respectively. Then, the samples of the transmission electron microscope and the atomic force microscope were made and observed.
RESULTSIn the human long bone tissue, many nerve fibers were distributed in the membrane, cortical bone, cancellous bone and marrow. The nerve fibers entered the bone from the nutrient foramen, and passed through the nutrient canal, Haversian's canal and Volkmann's canal, and finally into the bone marrow. In the nutrient canal, the nerve fibers, mainly the medullary nerve fibers, followed the blood vessel into the bone. In the cortical bone, the nerve fibers also followed the blood vessels and were mainly distributed along Haversian's canal and Volkmann's canal. In the bone trabecular and bone marrow, there were many nerve fiber endings arranged around the blood vessels, mainly around the tunica media of medium-size arteries in the marrow and around capillary blood vessels, and a few scattered in the bone marrow. There were sporadic nerve endings in epiphyseal plate and no nerve fibers permeated epiphysis to diaphysis. No distribution of nerve fibers could be found in cartilaginous part.
CONCLUSIONSThere are many nerve fibers in bone and the nerve passageway is nutrient foramen, Volkman's canal, Haversian's canal and bone marrow.

Objective To study the reliability of transcutaneous bilirubin (TCB) of different parts of neonates as predictive alarm of serum bilirubin ( SB ). Methods 132 cases of full-term neonates in Handan Central Hospital from May to July 2010 were divided into spontaneous delivery group and cesarean section group by random number. A KJ8000 transcutaneous bilirubinmeter was used to test their TCB at forehead, chest and abdomen on the fourth day after birth. The neonates were measured SB once TCB readings were more than 12.9 mg/dl. TCB of different parts and SB of the two groups were compared. Results The spontaneous delivery group had 17 cases of the. Neonates whose TCB readings were more than 12.9 mg/dl while the cesarean section group had 21 cases. TCB and SB of the same part by the same method showed no statistical significance between the two groups (t =0. 71, 2. 0, 1.25, 1. 0, 1.5;P >0. 05). TCB readings of chest were of no significant difference as compared with SB of the same group ( t =1. 72, 1. 33 ; P > 0. 05 ). Conclusions SB of the spontaneous delivery group and the cesarean section group was of no significant difference. TCB reading of chest was closer to SB.

A GeXP based multiplex PCR assay was developed to simultaneously detect six different chicken respiratory viruses including H5, H7, H9 subtypes of avian influenza virus(AIV), new castle disease virus (NDV), infectious bronchitis virus(IBV) and infectious laryngotracheitis virus(ILTV). According to the conserved sequences of genes of each pathogen, seven pairs of specific primers were designed, and the reaction conditions were optimized. The specificity and accuracy of GeXP were examined using samples of single and mixed infections of virus. The sensitivity was evaluated by performing the assay on serial 10-fold dilutions of cloned plasmids. To further evaluate the reliability, thirty-four clinical samples were detected by GeXP. The corresponding specific fragments of genes were amplified. The detection limit of GeXP was 10(2) copies/microL when all of 7 pre-mixed plasmids containing target genes of six chicken respiratory viruses were present. In the detection of thirty-four clinical samples, the results of GeXP were accorded with the viral isolation completely. In conclusion, this GeXP assay is a rapid, specific, sensitive and high-throughput method for the detection of chicken respiratory virus infections. It can be applied in rapid differential diagnosis for clinical samples, and also provide an effective tool to prevent and control chicken respiratory diseases with similar clinical symptoms.

OBJECTIVETo investigate the effective therapeutic method of human cytomegalovirus (HCMV) hepatitis in children.
METHODSTwenty-five children with HCMV hepatitis were randomly assigned to a treated group (n=13) or a control group (n=12). Both groups were treated with prednisone, glucurone, luminal and Xiaoyanlidanpian. But the treated group was given ganciclovir (GCV) + intravenous immunoglobulin (IVIG) in addition. Each infant of the two groups was checked for blood routine, liver function and HCMV copy numbers on admission and before discharge. They were seen at the third, sixth and ninth month after discharge. On each visit blood specimens were collected for HCMV copy numbers (fluorescence quantitative PCR, FQ-PCR).
RESULTSThe viral load of the treated group decreased significantly. A significant difference in viral copy numbers was found between the two groups on admission, discharge, and third, sixth and ninth month after discharge (P less than 0.001). The number of HCMV DNA copy fell to 10(3) copies/ml on discharge while that of the control group fell to the same level after the third month. The differences between the two groups in the length of hospitalization, time of initial jaundice disappearance and complete disappearance were statistically significant (P less than 0.05). The need for transfusion in the treated group was significantly less than that in the control group (chi-square=4.012, P less than 0.05).
CONCLUSIONCombination of GCV with a high dosage of IVIG to treat HCMV active infection could decrease viral load remarkably; The duration of disease, severity of symptoms, degree of anemia and the need for blood transfusion were reduced. No adverse effects related to the combination of GCV with IVIG therapy were observed.
