OBJECTIVE:To explore the effects of PDCA(plan,do,check,action)cycle theory in the ADR monitoring of our hospital. METHODS:The problems of ADR monitoring in our hospital in 2012 were analyzed and intervened by PDCA cycle. The effects of PDCA cycle were evaluated 1 year later. RESULTS:After implementation of PDCA cycle,we had improved the manage-ment system,brought ADR monitoring into the appraisal of clinical pharmacists,established the networking platform of ADR report-ing,strengthened the training of physicians and nurses,the publicty of ADR information and ADR monitoring of important medi-cine. The number of ADR reports increased by 18.37% in 2013,the proportion of new and serious ADR reports obviously in-creased(increasing from 22.28% to 38.42%);in terms of ADR reporting source,the ADR reporting in wards obviously increased (increasing from 8.16% to 43.84%). The proportion of ADR induced by antibiotics or TCM preparation decreased significantly(re-spetively decreasing from 54.52% to 43.84% and 23.03% to 13.30%);in term of ADR clinical manifestations,the proportion of skin and its appendants involved decreased significantly (decreasing from 53.64% to 39.41%). CONCLUSIONS:The application of PDCA cycle obviously improves the management of ADR monitoring in our hospital.

Objective To investigate the relationship between the expression of MMP-7 in peripher- al blood and esophageal cancer.Methods By using Real time RT-PCR, blood samples from 82 cases with postoperative esophageal cancer were detected.Results 37.8 %(32/82)patients were positive for MMP-7 mRNA expression.MMP-7 mRNA positivity significantly correlated with lymph node metastasis,stage,and hematogeneous metastasis.Recurrent disease was found in 28 of 82 cases. Of 28 patients experiencing re- lapse,15 patients were serially follow-up in every three months.The number positive of MMP-7 mRNA be- fore detection by imaging,at the same time of detection by imaging,and after detection by imaging was 5 cas- es,8 cases and 2 cases respectively.Conclusion Examination of MMP-7 mRNA in peripheral blood during follow-up is useful for early detection of occult recurrence.

The study was to research the clinical characteristics of Shenmai injection treating tumor based on hospital information system, including the characteristics of the age, the sex, the dosage, the course of the treatment and the combination drugs. The data of tumor patients injected with Shenmai injection was analyzed. The information was collected from the hospital information system (HIS) in twenty hospitals of grade III-A. The method of frequencies and association rules was used in this reaearch. The patients over 45 years old were up to 3 338, about 79.36% of the whole. The ratio of male and female was 1.73: 1. The hospitalization day between 15 and 28 was most. The complications of the hypertension and coronary heart disease happened most. The support was 5.939% and 5.099% respectively. Fifty-five patients had the traditional Chinese medicine (TCM) syndrome of Qi-Yin deficiency, about 14.78% of the whole. There were 8 491 patients treated with the single dose of 81 to 100 mL, about 48.70% of the whole. The main combination drugs were dexamethasone, tropisetron and maxolon. The confidence was 44.63%, 31.22% and 20.53% respectively. The information from HIS showed that tumor patients used Shenmai injection were most quinquagenarian with smooth condition. The dose of the Shenmai injection sometimes was higher than that of the drug use instructions in clinical. Shenmai injection was most often combined with glucocorticoid, antemetic and nutritional support medicine when treating tumor in clinical.

OBJECTIVESTo observe the influence of wen-yang herbs on the hemodynamics in liver fibrotic rats.

METHODSWistar rats with liver fibrosis, induced by carbon tetrachloride and alcohol, were randomly divided into a treatment group and a control group. The treatment group was administered wen-yang herbs and the control group saline. At the end of the experiment, the hemodynamic markers of the liver and the mesentery, the liver function and hydroxyproline content of liver tissues between the two groups were compared. Blood volume of the livers and hydroxyproline content of liver tissues were also determined.

RESULTSBlood volume of the liver and mesentery (P < 0.01) and blood flow velocity of small vein of mesentery (P < 0.05) of the treatment group were distinctly higher than the control group. The hydroxyproline content (P < 0.01) of the treatment group was remarkably reduced and liver function was improved.

CONCLUSIONWen-yang herbs can activate microcirculation of the liver and mesentery, decrease the deposit of collagen in the liver and improve liver function.

OBJECTIVETo observe the effect of Ganzhifu (GZF), a Chinese compound formula for Warming-yang on experimental hepatic fibrosis, and to explore its mechanism.

METHODSFifty-nine Wistar rats were divided into the normal control group and the model group. After the hepatic fibrosis model was established in rats by subcutaneous injection of CCl4 and feeding 10% alcohol in the model group, the rats were randomly sub-divided into the Ganzhifu group, colchicine group and model group, they were treated with Ganzhifu, colchicine and normal saline of same volume once a day respectively for 30 days as one treatment course. The serum liver function and hepatic fibrosis indexes, liver tissue contents of hydroxyproline (Hyp), malondialdehyde (MDA) and superoxide dismutase (SOD) activity were measured at the end of the experiment. Histologic changes of liver tissue were observed and scored by the modified inflammatory activity and fibrosis semiquantative scoring system (SSS), and collagen type I , III and IV in liver tissue were stained and semiquantitive analysis conducted.

RESULTSIn the Ganzhifu group, liver function and inflammatory activity and fibrosis SSS scores were markedly improved, indexes of hepatic fibrosis, liver contents of Hyp, MDA and collagen type I, III and IV were significantly decreased, and the SOD activity was increased, the changes were more significant as compared with those in the model group. The protective effect of Ganzhifu against hepatic fibrosis was the same as that of colchicine.

CONCLUSIONGanzhifu can alleviate or reverse hepatic fibrosis in experimental hepatic fibrosis, and antioxidation may be its mechanism.

OBJECTIVETo observe the effect of acupuncture on proliferation and differentiation of neural stem cells in brain tissues of rats with traumatic brain injuny.

METHODSThirty SD rats were randomly and equally allocated to the sham-operated, the model and the acupuncture groups. The traumatic brain injury model was established by the free drop method. For the rats in the acupuncture group, acupuncture was applied once a day for 7 days. Brain histotomy was carried out when treatments were completed. Immunohistochemical techniques were adopted to detect the cells that express nestin, neurofilament proteins (NF)-200 and glial fibrillary acidic proteins (GFAP), the markers of neural stem cells, neurons, astrocytes respectively.

RESULTSCompared to the sham-operated group, the number of nestin-positive cells and NF-200-positive cells in brain tissues was decreased significantly in the model group (P < 0.01), whereas the number of GFAP-positive cells was significantly increased P<0.01). Compared to the model group, the positive cells of nestin, NF-200, GFAP in brain tissues in the acupuncture group were increased obviously (P<0.01).

CONCLUSIONSAcupuncture can significantly increase the number of nestin-positive cells, NF-200-positive cells and GFAP-positive cells, indicating the significant increase of neural stem cells, neurons and astrocytes in number. Acupuncture can improve neuranagenesis by promoting the proliferation and differentiation of neural stem cells in brain tissues. This might be one of the mechanisms for acupuncture to treat traumatic brain injury and to promote the repair of nervous function.

OBJECTIVETo study the impact of the chloride channel dysfunction of the cystic fibrosis transmembrane conductance regulator (CFTR) on the cytoskeleton of Sertoli cells in the mouse.

METHODSTM4 Sertoli cells were cultured and treated with CFTR(inh)-172 at the concentrations of 1, 5, 10 and 20 μmol/L for 48 hours. Then the cytotoxicity of CFT(inh)-172 was assessed by CCK-8 assay, the expressions of F-actin and Ac-tub in the TM4 Sertoli cells detected by immunofluorescence assay, and those of N-cadherin, vimentin and vinculin determined by qPCR.

RESULTSCFTR(inh)-172 produced cytotoxicity to the TM4 Sertoli cells at the concentration of 20 μmol/L. The expressions of F-actin and Ac-tub were decreased gradually in the TM4 Sertoli cells with the prolonging of treatment time and increasing concentration of CFTR(inh)-172 (P < 0.05). The results of qPCR showed that different concentrations of CFTR(inh)-172 worked no significant influence on the mRNA expressions of N-cadherin, vimentin and vinculin in the Sertoli cells.

CONCLUSIONThe CFTR chloride channel plays an important role in maintaining the normal cytoskeleton of Sertoli cells. The reduced function and expression of the CFTR chloride channel may affect the function of Sertoli cells and consequently spermatogenesis of the testis.

OBJECTIVETo investigate the utilization of carrier for delivering osteoblasts and creating autogenous bone tissue in ectopic site of animal via injection.

METHODSBone marrow cells harvested from iliac bone of New Zealand rabbits were induced to differentiate into marrow stromal osteoblasts. The osteoblasts were mixed with 1.5% alginate sodium solution to generate osteoblasts/alginate composites with final cellular density of 4 x 10(9)/L. Calcium chloride was used as cross-linking agent to gel aqueous alginate solution. The marrow stromal osteoblasts/alginate composites were injected into the dorsal subcutaneous tissue of rabbits with autogenous cells transplantation. The samples were examined with X-ray and histological analysis.

RESULTSFour, eight and twelve weeks after injection, the hard knobbles were easily palpated under the dorsal skin of animals. On X-ray photograph the samples showed calcified image with more density than surrounding soft tissue, new bone formation was observed in the osteoblasts/alginate composites in histological analysis. The osteogenesis was in association with regenerated hematopoietic bone marrow.

CONCLUSIONSThese results demonstrate that new bone tissue could be created through the injection of alginate sodium treated with autogenous marrow stromal osteoblasts.

OBJECTIVETo summarize the clinical changing characters of the clinical markers after interferon treatment in chronic hepatitis B (CHB) and make out practical indexes to predict the effect.

METHODS150 CHB patients were randomly divided into two groups: therapeutic group (90) and control group (60) in the prospective controlled trial. The levels of endogenous interferon before treatment, interferon antibody at the end of the second month and fourth month after treatment, alanine aminotransferase (ALT) and HBV DNA in the serum were detected. Then the data was analysed to find out indexes for predicting the effect.

RESULTS(1) The clearance rate of HBeAg had no significant difference in age except for 20 - 30 and 30 - 40 (t > 2.331 2, P < 0.01). (2) It was more effective if ALT level was higher than 400 U/L before treatment and it decreased more than 50% two months after treatment. (3) The patients whose HBV DNA was negative (dot hybridization) or less than 10(6) copies/ml before treatment had higher rate of HBeAg clearance. (4) There was no effect on patients whose interferon antibody turned positive at the end of the second month. (5)A predictive method of comprehensive factors was made out, whose sensitivity, specificity, and accuracy were 80%, 100% and 90%, respectively.

CONCLUSIONThe clinical characters of these Chinese patients are different from those of the westerners and the effects of interferon have close relation to the levels of ALT, HBV DNA and interferon antibody.

OBJECTIVESTo evaluate if the humoral immune response of hepatitis B DNA vaccine pVAX1-S2S could be enhanced by Talpha1 and/or IFNa expression plasmid co-inoculated.

METHODSThe following mammalian expression recombinant plasmids were constructed: the plasmid pVAX1-S2S expressing hepatitis B surface antigen S2S, the plasmid pVAX1-T/I co-expressing thymosin a and IFNalpha, the plasmid pVAX1-I/S2S co-expressing IFNalpha and S2S. These plasmids were inoculated intramuscularly into several BALB/c mice groups in different combinations. In the co-immunization group 1 (pVAX1-I/S2S), each mouse was inoculated with 100 microg of pVAX1-I/S2S; in the co-immunization group 2 (pVAX1-S2S) each mouse was co-inoculated with pVAX1-S2S and 50 microg of pVAX1-TI; in the control group each mouse was inoculated with 100 microg of pVAX1-S2S. All the immunizations were boosted at 2 and 4 week intervals; then the serum samples were collected to detect the anti-HBs and anti-preS2 strengths.

RESULTS3, 5 and 8 weeks after the first inoculation, the positive rates of anti-HBs were 12.5%, 12.5%, 62.5% respectively in the co-immunization group 1 and 25%, 50%, 50% in the co-immunization group 2, while those in the control group were 0, 25%, 37.5%. The titers of anti-preS2 in co-immunization group 2 was 5 times higher than those in the other two groups.

CONCLUSIONThe data shows that Talpha1 and/or IFNalpha expression plasmid co-inoculated with pVAX1-S2S might act as an adjuvant to enhance the humoral immune response induced by pVAX1-S2S.
