OBJECTIVE:To investigate the dosage and consumption sum of opioid analgesic drug in Qingdao district. METH-ODS:The consumption data of drugs in 29 public hospitals at secondary or above level in Qingdao district were analyzed statistical-ly by ABC analytic methods and defined daily dose methods. RESULTS:In ABC analysis,5 kinds of class A drugs accounted for 20% of the total number of species,and the percentage of consumption sum was 77.38%;4 kinds of class B drugs accounted for 16.00% of all species numbers,and the percentage of consumption sum was 11.98%;other 16 kinds of drugs accounted for 64.00% of the total number of species,and the percentage of consumption sum was 10.64%. Oxycodone sustained-release tablets and Morphine sustained-release tablets with the highest DDDs consumed more health care costs,serial number ratio was 1.00,syn-chronization was good and conform to the actual needs of clinical work. CONCLUSIONS:The composition ratio of opioid analge-sic drug costs is consistent with the theoretical value,significant discrepancy between cost and DDDs does not appear.

Objective Assisted reproductive technology ( ART) is associated with an increased incidence of offspring de-fects.The aim of this study was to investigate the impact of embryo vitrification in in vitro fertilization ( IVF) on the growth and devel-opment of the offspring by comparing the development status of mouse offspring from fresh embryo versus vitrified embryo transplanta-tion. Methods This study included three groups of mouse offspring , from natural fertilization ( n=12 ) , fresh embryo transplanta-tion (FET, n=9), and vitrified embryo transplantation (VET, n=9).We compared the body weight and body fat content in the sex-ually mature stage among the three groups of mice . Results No obvious differences were found in the morphology of the embryos be-tween the FET and VET groups .The body weight of the mouse offspring was significantly higher in the VET than in the natural control group at 0 postnatal (PN) week (P<0.01) and 12 PN weeks (P<0.01), and so was it in the FET group than in the control at 0 PN week (P<0.01) and 6 PN weeks (P<0.05).The body fat content at sexual maturity was remarkably higher in the VET than in the FET and control groups ([9.32 ±4.34] vs [5.24 ±2.56] and [2.80 ± 0.48] g, P<0.05), and so was the muscle content in the VET than in the control ([33.77 ±4.22] vs [27.50 ±1.79] g, P<0.01). Conclusion In IVF, fresh embryo transplantation has less interference with the growth and development of mouse offspring than vitri-fied embryo transplantation .

Background The domestic and international researches discovered that many proteins and enzymes of the extracellular matrix (ECM) participate in the sclera remodeling by affecting the collagen typeⅠand fibronectin.Objective This study was to investigate the effect of matrixmetalloproteinase-2 (TIMP-2) on expression of collagen typeⅠand fibronectin of ECM in the posterior sclera by injecting liposomes containing tissue inhibitor of TIMP-2 gene into suprachoroidal space of the form-deprivation myopia in guinea pig.Methods Form-deprivation myopia was induced by translucent goggles in 36 clean guinea pig for 2 weeks.Then the animals were randomly assigned to TIMP-2 group,empty plasmid group,saline group and 12 for each group.Liposomes of 5μl containing TIMP-2 gene,empty plasmid and saline were suprachoroidally injected in the right eye respectively,and the left eyes without any treatment were used as self-control group.Other 12 matched guinea pigs only covered the right eyes through out the experimental duration as model control group.The guinea pigs were sacrificed and the posterior sclera tissue of the eyeballs were collected at 2,7 and 14 days after injection of drug.The expressions of collagen typeⅠmRNA and fibronectin mRNA were detected by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR).This study followed the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The expression level of collagen type Ⅰ mRNA in the posterior sclera of guinea pig was lower but that of fibronectin mRNA was higher in TIMP-2 group than self-control group,showing significant differences between them (P<0.05).The expression level of collagen type Ⅰ mRNA in the posterior scleral tissue began to increase from the 2nd day after drug injection and was obviously elevated at the 7th day and then gradually decreased at the 14th day.However,the expression level of fibronectin mRNA in the posterior scleral tissue showed the opposite pattern.The expression levels of collagen typeⅠmRNA and fibronectin mRNA at the 7th after drug injection were significantly lower than that at the 2nd day or 14th day (P<0.01).Conclusion Suprachoroidal injection of TIMP-2 in form-deprivation myopia could up-regulate the expression of collagen typeⅠmRNA and down-regulate the expression of fibronectin mRNA in the posterior scleral tissue.It may slow down the sclera remodeling of form-deprivation myopia in guinea pig in the early stage.

4-coumarate coenzyme A ligase is a key enzyme of phenylpropanoid metabolic pathway in higher plant and may regulate the biosynthesis of ferulic acid in Angelica sinensis. In this study, the homology-based cloning and rapid amplification of cDNA ends (RACE) technique were used to clone a full length cDNA encoding 4-coumarate coenzyme A ligase gene (4CL), and then qRT-PCR was taken for analyzing 4CL gene expression levels in the root, stem and root tissue at different growth stages of seedlings of A. sinensis. The results showed that a full-length 4CL cDNA (1,815 bp) was obtained (GenBank accession number: KT880508) which shares an open reading frame (ORF) of 1 632 bp, encodes 544 amino acid polypeptides. We found 4CL gene was expressed in all tissues including leaf, stem and root of seedlings of A. sinensis. The expressions in the leave and stem were increased significantly with the growth of seedlings of A. sinensis (P < 0.05), while it in the root showed little change. It indicates a time-space pattern of 4CL gene expression in seedlings of A. sinensis. These findings will be useful for establishing an experiment basis for studying the structure and function of 4CL gene and elucidating mechanism of ferulic acid biosynthesis and space-time regulation in A. sinensis.

OBJECTIVE: To observe the effects of salvianolate on rats with postoperative intestinal adhesion and to explore the prevention mechanism. METHODS: Forty SD male rats with intestinal adhesion were randomly divided into four groups: untreated group, low-dose salvianolate-treated group (12 mg/kg), medium-dose salvianolate-treated group (24 mg/kg) and high-dose salvianolate-treated group (48 mg/kg), with another ten SD male rats as normal control. Intraperitoneal injection of glucose was administered to the rats in the normal control group and the untreated group, and intraperitoneal injection of salvianolate was administered to the rats in the low-, medium- and high-dose salvianolate-treated groups. They were all treated for 8 days and once a day. On the eighth day after surgery the blood samples of each group were collected. Grades of intestinal adhesion were ranked by macroscopic observation. The adhesive tissues between viscera and belly wall were taken for pathological observation. The levels of interleukin-1beta (IL-1beta), interleukin-4 (IL-4) and tumor necrosis factor-alpha (TNF-alpha) were determined by enzyme linked immunosorbent assay. RESULTS: Salvianolate can significantly reduce the extent of postoperative intestinal adhesion, obviously decrease the levels of IL-1beta, TNF-alpha and inhibit the hyperplasy of fibrous connective tissue. However, there was no significant impact on the level of IL-4. CONCLUSION: Salvianolate can reduce the extent of postoperative intestinal adhesion, decrease the expression of IL-1beta and TNF-alpha and inhibit the hyperplasy of fibrous connective tissue. This may be the mechanism of salvianolate in preventing intestinal adhesion.

OBJECTIVETo investigate the effect of adenovirus-mediated endostatin gene transfer on transplanted lung cancer in mice and its mechanism of action.
METHODSTransplant tumor model was induced by subcutaneous inoculation of 2 x 10(6) Lewis lung cancer (LLC) cells into the back of C57BL/6 mice. The mice were treated by intratumoral injection of 2 x 10(9) pfu Ad-mEndostatin. The expression of endostatin in situ and its maintaining time were detected by immunohistochemistry and Western Blot, respectively. The endostatin level in serum was determined by ELISA . The inhibition of tumor growth and changes of survival were recorded and the microvessel density (MVD) was determined by histochemical stainingwith CD31 and CD105 antibodies. The tumor apoptosis was observed by electron microscopy.
RESULTSIn comparison with controls, intratumoral injection of Ad-mEndostatin significantly inhibited the tumor growth and metastasis, and prolonged the survival rate of mice (P < 0.05). Strong positive expression of mEndostatin was seen in the tumor tissue after injection of Ad-mEndostatin, immunhistochemically ostained by mouse endostatin monoclonal antibody, while the control groups showed only very low expression or absence. Serum endostatin concentration was 1540 +/- 560 ng/ml at the second week of administration, the expression of endostatin diminished a month later. The microvessel density (MVD)) decreased from 42.4 +/- 4.8 to 10.5 +/- 3.2 per x 200 magnificetion microscopic field by CD10 staining and from 68.5 +/- 4.5 to 37.5 +/- 4.6 by CD31 staining, respectively (P < 0.05). More apoptotic tumor cells were seen under the transmission electron microscope.
CONCLUSIONEndostatin gene therapy mediated by adenoviral vector efficiently induces expression of endostatin in vivo, and inhibits the growth and metastasis of tumor. It is concluded that its action is targeted to tumor neovasculature and the mechanism is inhibition of tumor angiogenesis.

OBJECTIVETo investigate the role of extracellular regulated kinase (ERK1/2) pathway in cisplatin-induced apoptosis in human ovarian carcinoma cells.
METHODSCisplatin-induced apoptosis were stained with DAPI and was assessed microscopically in human epithelial adenocarcinoma ovarian cell line SKOV3 cells. ERK activation was determined by Western blotting using an anti-phospho-ERK antibody to detect ERK activity. The effect of PD98059 on ERK activity induced by cisplatin was detected by MTT assay.
RESULTSMarked apoptosis of SKOV3 cells resulted from 48 hours treatment with 20 microg/mL cisplatin. Strong activation of ERK was led to by 15 microg/mL cisplatin. Dose response and time course of cisplatin induced apoptosis in SKOV3 cells. Cisplatin-induced ERK activation occurred at 12 hours and increased to highest induction at 24 hours by Western blotting. The effect of PD 98059 on ERK activity induced by cisplatin at the concentration of 100 micromol/L PD 98059. Statistically significant decreased in cell survival were observed with 100 micromol/L PD 98059 at 15 and 20 microg/mL cisplatin (P < 0.05).
CONCLUSIONSCisplatin activates the ERK signaling pathway in ovarian cancer cell line SKOV3. Inhibition of ERK activity enhances sensitivity to cisplatin cytotoxity in ovarian cancer cell line SKOV3. Evaluation of ERK activity could be useful in predicting which ovarian cancer will response most favorably to cisplatin therapy.

OBJECTIVETo investigate the effects of diet-induced obesity on the developmental process of testes in pubertal rats.
METHODSEighty 21-day-old male SD rats were randomly divided into a control group (n=32) and an experiment group (n=48), and fed respectively on a normal diet and a high-fat diet. And changes in the body weight, Lee's index, testis weight and epididymis weight were measured at the end of the 3rd, 4th, 5th and 6th week after the treatment, that is, when the rats were 6, 7, 8 and 9 weeks old. The concentrations of testosterone and estradiol were determined by Access immunoassay system and the morphological alterations in testis development observed by HE staining.
RESULTSThe body weight of the high-fat group obviously increased at the end of the 3rd week (P < 0.05), 26.6% heavier than that of the control by the end of the 6th week (P < 0.01), and Lee's index was also obviously increased (P < 0.01). Compared with the controls, the testicular coefficient declined in the high-fat group at the end of the 5th and 6th week (P < 0.05), plasma TG and TC remarkably increased, the testosterone level obviously decreased (P < 0.05), estradiol concentration lowered at the end of the 3rd, 4th and 5th week but dramatically increased at the 9th, with significant difference between the two groups (P < 0.01). Microscope examination showed that spermatogenic epithelial cells were arranged in disorder, the spermatogenic cell layers reduced and the number of mature sperms reduced.
CONCLUSIONHigh-fat diet can induce nutritional obesity in pubertal rats, which in turn may lead to the underdevelopment of the testis and the abnormal level of gonadal hormones.
