OBJECTIVE: To investigate the characteristics and causes of adverse drug reactions (ADR) in Jiangxi region in order to improve the rational use of drug in clinic. METHODS: A total of 10 033 cases of ADR reports collected in Jiangxi region in 2008 were classified and analyzed statistically. RESULTS: The ADR were predominantly induced by antimicrobial drugs (53.76%), followed by TCM preparation (16.68%). Intravenous administration was the main cause of ADR(65.45%). 225 case of severe ADR reports accounted for 2.24% and 412 cases of new ADR reports 4.11%. 99 cases of severe ADR were characterized by the systematic damages.12 death cases and 12 sequelae cases were involved in 225 cases of severe ADR reports. CONCLUSION: Great importance should be attached to ADR monitoring, reporting and publicizing to promote rational use of drug in clinic.

Objective To explore the significance of signal and volume change from magnetic resonance imaging (MRI) of hysteromyoma before and after uterine artery embolization (UAE) in the therapy evaluation. Methods MRI was performed in 30 patients (50 hysteromyoma) before and 3,6 and 12 months after UAE. They were grouped by location, signal and size. The MRI signal changes and the hysteromyoma's volume reduction ratio were measured. Results After 3,6,12 months, MRI of hysteromyoma was changed significantly, and all hysteromyomas had lower T2WI signals than before, some of which had higher T1WI signals. Hysteromyoma's volumes were progressively reduced, the majority of which shrinked significantly within 3 months. Evaluated by 12 month's volume changes, significant volume reduction was found in submucous fibroids, and significant difference was showed compared with intramural fibroids and subserosal fibroids (88.9 % vs. 73.7 % and 68.3 %, P=0.036, P=0.019), meanwhile,the latter two had no significant difference (P=0.384). The volume reduction rate in rich cell fibroids was higher than those in ordinary no degeneration fibroids and degeneration type, and there were significant differences (85.7 % vs. 72.1 % and 63.4%, P=0.038, P=0.014). Besides, the latter two had no significant difference (P=0.364). Large fibroids shrinked more obviously than small ones with significant difference (75.2 % vs. 59.6 %, χ2=4.563, P=0.044). Conclusion MRI is useful for the evaluation of efficacy in hysteromyoma before and after UAE, which can provide the better interventional treatment for the patients in regard to different sensitivity of hysteromyoma to UAE.

Objective To compare the anterograde amnesia produced by midazolam,propofol and dexmedetomidine when used to supplement sedation during neuraxial anesthesia.Methods Sixty patients of both sexes,aged 18-50 yr,with body mass index of 23-26 kg/m2,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective operation on lower limbs with neuraxial anesthesia,were divided into 3 groups (n =20 each) using a random number table:midazolam group (group M),propofol group (group P) and dexmedetomidine group (group D).When the height of anesthesia was kept below T10,midazolam in a loading dose of O.05 mg/kg was intravenously injected in group M,propofol in a loading dose of O.4 mng/kg was intravenously injected in group P,and dexmedetomidine in a loading dose of 0.6 μg/kg was intravenously injected in group D.The infusion rate of the 3 drugs was adjusted to maintain bispectral index value at 82-86.When Observer's Assessment of Alertness/Sedation Scale scores achieved 3 or 4 after administration,anterograde amnesia was measured by postoperative recall of cards.The development of intraoperative hypotension,bradycardia and respiratory depression was recorded.Results Compared with group M,the incidence of global amnesia was significantly decreased in P and D groups (P＜0.05).There was no significant difference in the incidence of global amnesia between group P and group D (P＞ 0.05).No patients developed hypotension,bradycardia or respiratory depression in three groups.Conclusion Midazolam produces better anterograde amnesia than propofol and dexmedetomidine when used to supplement sedation during neuraxial anesthesia.

Objective To assess the role of the different pancreatic islet β cell function index in the evaluation of glucose metabolism in different duration of type 2 diabetes mellitus (T2DM).Methods Normal glucose tolerance subjects without diabetes family history (NC group,48 cases) and T2DM patients (182 cases) were enrolled.The T2DM patients were divided into three groups:less than 5 years group (DM ＜5 group,74 cases),5-10 years group (DM5-10 group,51 cases) and more than 10 years group ( DM ＞10 group,57 cases).Oral glucose tolerance test (OGTT) and insulin release test were taken in all groups.Insulin resistance index (HOMA-IR) and whole body insulin sensitivity index [ISI(Matsuda)] were used to estimate insulin sensitivity,and early insulin secretion index ( △ I30/ △ G30) and glucose disposition index (DI) were used to evaluate the function of pancreatic islet β cell.Results HOMA-IR was increased and ISI (Matsuda) was decreased in DM ＜5 group,DM5-10 group and DM ＞10 group compared with those in NC group [HOMA-IR:8.78 ± 7.12,8.08 ± 3.67,7.84 ± 5.08 vs.4.76 ± 3.43;ISI(Matsuda):46.78 ± 29.00,36.71 ± 16.67,38.86 ±21.72 vs.61.13 ± 32.08,P ＜ 0.05],however,there was no significant difference among DM ＜5 group,DM5-10 group and DM ＞10 group.△ I30/ △ G30 and DI were decreased in DM ＜5 group,DM5-10 group and DM ＞10 group compared with those in NC group [ △ I30 △ G30:( 68.41 ± 361.52 ),(4.31 ± 3.42 ),(7.70 ± 5.78 ) mU/mmol vs.(92.65 ± 309.29) mU/mmol;DI:0.0421 ± 0.0123,0.0412 ± 0.0123,0.0363 ± 0.0116 vs.0.1151 ± 0.0236,P ＜ 0.05 ],and there was no significant difference in △ I30 / △ G30 among DM ＜5 group,DM5-10 group and DM ＞10 group,however,DI was decreased in DM＞10 group compared with that in DM＜5 group and DM5-10 group (P＜0.05).ConclusionsHOMA-IR,ISI (Matsuda),△I30/△G30 are not sensitive to evaluate the insulin resistance of different duration.DI can reflect the glucose utilization of pancreatic islet β cell earlier and the ability to regulate blood sugar steady state changes.

Objective To study the relationships of hemoglobin(Hb)level with the levels of neurohormones,and cytokines,and the effect of them on ventricular remodeling in patients with congestive heart failure(CHF). Methods Hb level,serum angiotensinⅡ(Ang Ⅱ ),tumor necrosis factor-α(TNF-α),nitric oxide(NO),soluble intereellular adhesion molecule-1(sICAM-1)and B-type natriuretic peptide(BNP)were measured in 121 CHF patients.The left ventrieular ejection fraction (LVEF)from echocardiography,left ventricular mass index(LVMI),and mean wall stress(MWS)were calculated. Results The levels of Ang Ⅱ,TNF-α,NO,siCAM-1,BNP[(144.5±64.1)ng/L,(92.3±6.4)ng/L,(65.2±4.2)μmol/L,(253.6±26.0)μg/L,(1294.0±223.0)ng/L]and LVMI,MWS in the anemia group of CHF patients were higher than those in the non-anemia group[(76.7±48.5)ng/L,(55.6±10.2)ng/L,(42.1±11.9)μmol/L,(237.18±33.26)μg/L,(437.0±115.0)ng/L,all P＜0.01].With the increase of anemia severity,the levels of AngⅡ,TNF-α,NO,siCAM-1,BNP and LVMI,MWS were significantly increased.There were negative correlations between Hb level and the 1evels of AngⅡ,TNF-α,NO,siCAM-1,BNP,LVMI,MWS(r=-0.8173,-0.8509,-0.6001,-0.6692,-0.6283,-0.8604,-0.8733,all P＜0.01),and negative correlations between LVMI,MWS and Hb levels and LVEF(P＜0.01). Conclusions Neurohormones and cytokines play roles in ventrieular remodeling and anemia in CHF aggravates the severity of ventricular remodeling.

Objective To observe the effect of liver disease special-purpose enteral nutrition preparation on protein metabolism and liver function in children with liver injury.Methods Sixty cases of severe ill with liver injury in hospital,with mean age of (7.8?6.3) years old.All patients were randomly divided into experimental group (n=30) and control group(n=30).The experimental group was treated by adding the liver disease special-purpose enteral nutrition preparation homogenized diet and control group was treated by adding entire protein entire nutrition type enteral nutrition preparation.All patients in both 2 groups were nasally fed with intestinal nutrition,which contained 418-628 kJ/(kg?d).One day before nutritional support and 14 days after nutritional support,the liver function,total serum protein,albumin,hemoglobin were recorded.SPSS 11.5 software was used to analyze the data.Results The baseline indicators were similar before nutritional supports.Fourteen days after nutritional support,alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were all significantly lower in experimental group than in control group(Pa

The purpose of this study is to prepare galactosyl modified lipid bilayer-coated mesoporous silica nanoparticles (GPEM) to enhance the antitumor efficacy against hepatocellular carcinoma cells. The irinotecan (CPT-11) loaded mesoporous silica nanoparticles (MSNs) was coated with the Gal-P123 modified functional lipid bilayer by thin-film dispersion method. Nanoparticles were characterized with particle size, zeta potential, morphology and drug release in vitro. Afterwards, the cell uptake, intracellular concentration of CPT-11, cell apoptosis rate and cytotoxicity were evaluated on human hepatocellular carcinoma cell line Huh-7. The results showed that MSNs were coated with intact lipid bilayers and the nanoparticles had clear core-shell structure. GPEM is stable with the mean particle size of (78.01 +/- 2.04) nm. The low leakage rate in normal physiological conditions in vitro is contributed to the protection of stable lipid bilayer, and the fast drug release in acid environment due to the destruction of the lipid bilayer. On the cell level, the vector could improve the intracellular CPT-11 concentration by 4 times because of the functional lipid bilayer. The high CPT-11 concentration led to the increasement of apoptosis rate by 48.6%, and the reduction of half maximal inhibitory concentration (IC50) values of CPT-11 by 2 times, indicating stronger cell cytotoxicity.
