OBJECTIVE: To investigate the tagging condition in medication of special population in package inserts in order to give reference for rational drug use of special population. METHODS: 389 pieces of common Chinese and western medicine package inserts of our inpatient and out-patient dispensaries were randomly collected and analyzed statistically in terms of the content of package inserts for special population, including pregnant and lactant women, children and the aged. RESULTS: A part of medication items of special population in package inserts had deficiency. According to the classification of dosage form, the tagging rate of injection exceeded other dosage forms reached to more than 90%, except of medication items for children. The tagging rate of oral formulation arrived at more than 90% only in terms of contraindications and cautions. According to the classification of manufacturer, the tagging rate of domestic drugs was kept at the low level while that of imported drugs exceeded 90%. CONCLUSIONS: Package inserts need to be improved with the effort of drug supervision management department, drug production department and population of using drugs to guarantee the safety of drug use in special population.

Objective To investigate the relationship between plasma D-lactate levels and prognosis in newborns with neonatal necrotizing enterocolitis (NEC).Methods One hundred and four premature infants with NEC (stase Ⅱ and Ⅲ ) and another 104 premature infants without NEC admitted into Quanzhou Children's Hospital for other diseases from January 2007 to October 2010 were selected into this case control study.The gestational age,gender and birth weight of patients in the two groups were matched.NEC patients' bloods were collected within 24 hours after NEC was confirmed and blood samples of the control group were collected at the corresponding age.Enzymelinked immunosorbent assay was used to detect the plasma D-lactate level.Receiver operating characteristic curve was used to confirm the criteria of D-lactate positive,according to which,the NEC group was divided into high D-lactate group and normal D-lactate group,and the mortality and complication rate of the two groups were compared with x2 test.And NEC group was subdivided into death group and survive group according to the prognosis of the patients,and the difference of D-lactate level between the two groups were compared with t test.Results Among the NEC group,there were 63 cases (60.6％) of stage Ⅱ and 41 (39.4％) cases of stage Ⅲ ; 88 (84.6％) survived infants and 16 (15.4％) dead infants.D-lactate level was (35.4 ± 29.1) μg /ml in stage Ⅲ NEC group,(29.5±16.2) μg/ml in stage Ⅱ NEC group and (3.7±18.4) μg/ml in control group; there were statistical differences between each other(F=5.97,P＜0.05).Receiver operating characteristic curve analysis showed that if 6 μg/ml was set as the borderline,there were 87 cases(83.7％,87/104) with high D-lactate patients in NEC group,whose neonatal critical illness scoring (NCIS) was 80.9±22.6,significantly lower than that of normal D-lactate patients ( 95.8 ± 20.5) (t =2.417,P＜ 0.05),and higher neonatal septicemia rate (48.3％,42/87) and mortality (27.6％,24/87) compared with those [(5.9％,1/17) and (5.9％,1/17)] of normal D-lactate patients(x2 =11.539 and 7.146,P＜0.05,respectively).In NEC group,compared with the survived infants,the D-lactate level [(43.2±13.5) μg/ml vs (21.9 ± 22.9) μg/ml,t =4.572,P＜0.05] and the rate of septicemia [68.8％ (11/16) vs 38.6％ (34/88),x2 =3.445,P＜0.05] were higher in dead patients,and NCIS (82.4± 29.1 vs 90.6 ± 21.3,t =2.409,P＜0.05) was lower.Conctusions The level of plasma D-lactate related to the prognosis of neonatal NEC and which might be a good indicator for its prognosis and severity.

Objective To investigate the clinical value of the variety of serum levels of soL-CXCL16 and NT-proBNP peripercutaneous coronary intervention(PCI) in patients with acute myocardial infarction (AMI).Methods A total of 77 cases received PCI were selected to research group.And the contemporaneous 30 healthy persons were chosen to control group.The serum levels of soL-CXCL16,NT-proBNP and cTnT were detected by ELISA.The relationships of soL-CXCL16 and NT-proBNP to cTnT were detected by Pearson linear correlation analysis.Results Compared to pre-PCI,the serum levels of CXCL16 were rising to the peak point at 0.5 h post-PCI,and were decreasing from 2.0 h post-PCI,then the serum levels of CXCL16 were declining to the levels of pre-PCI at 24.0 h post-PCI (P＜0.05).And the serum levels of NT-proBNP were rising from 0.5 h post-PCI,and the peak point was at 24.0 h post-PCI (P＜0.05).The postive relationships of the serum levels of CXCL16 and NT-proBNP to the serum levels of cTnT were confirmed by Pearson linear correlation analysis(P＜0.01).Conclusion Monitoring of soL-CXCL16 and NT-proBNP for patients with percutaneous coronary stenting could provide foundation for prognosis evaluation of PCI.

OBJECTIVE:To provide reference for the practice of monitoring on adverse drug reactions (ADRs) in secondary or inferior to secondary medical institutions.METHODS:The problems in the practice of ADR monitoring in secondary or inferior to secondary medical institutions were analyzed and the approaches to strengthen the ADR monitoring was discussed taking our hospital as an example.RESULTS & CONCLUSIONS:The problems in the practice of ADR monitoring in secondary or inferior to secondary medical institutions manifested as low general technical level,lacking of advanced information network,hospital leaders' negligence,medical staff's poor consciousness,pharmacy departments' failure in bringing their role into full play,etc.Therefore,it is urgent to attach great importance to the problems to facilitate the development of ADR monitoring by enlarging publicizing,raising awareness;improving the organizational structure and the related working rules,bringing clinical pharmacists and nursing staff's roles into full play and establishing the reward and punishment mechanism,etc.

AIM: To investigate whether the bcl-2 antisense oligonucleotide increases the sensitivity of HL60 and K562 cell lines to daunorubicin. METHODS: IC50 for HL60 and K562 was determined with MTT method, the expression levels of Bcl-2 protein were assayed by immunofluorescence using fluoresce isothiocyanate labeling. In addition, apoptosis was detected by morphological observation and flow cytometric analysis of DNA fragmentation. RESULTS: It was found that the two oligonucleotides directed against the coding region and the translation initiation of bcl-2 mRNA, combined respectively with daunorubicin, inhibited expression of bcl-2 protein, increased apoptosis in HL60 and K562 cells, and decreased IC50 of daunorubicin significantly ( P

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) can be induced to differentiate into neuron-like cells in new environment after transplantation, and then to replace damaged cells for reconstructing neural circuit. OBJECTIVE: To establish the co-culture system between rat BMSCs and neural cells in vitro, and to study the influence of neural cells on the differentiation of BMSCs into neuron-like cells in the co-culture system. METHODS: The neural cells obtained from Wistar rat fetal brain tissue and BMSCs gained from rat thighbone were co-cultured in Transwell culture plate. The morphological changes of BMSCs were observed and the special markers of neural cells in BMSCs were examined by immunofluorescence on the fifth day of the co-culture. The results were compared with control group which where BMSCs were alone cultured. RESULTS AND CONCLUSION: BMSCs in the neural cells co-culture system extended, were radial, connected each other. Neuron specific enolase immunoreactions showed positive results, showing neuron-like cells. The positive ratio of neuron specific enolase-positive cells was (33.0±10.5)%. However, BMSCs in the control group did not express neuron morphological character. Immunofluorescence exhibited that cells were negative for neuron specific enolase. These indicate that microenvironment provided by neurons improves the differentiation of BMSCs into neuron-like cells.

Objective To investigate the effect of pregnancy on the potency of bupivacaine for spinal anesthesia in rats. Methods Female non-pregnant SD rats weighing 180-220 g and 17 day pregnant SD rats weighing 350-400 g were used in this study. The rats ( 18 non-pregnant, 18 pregnant) in which PE-10 catheter were successfully placed without complications were selected. The 18 non-pregnant rats were randomly divided into 3 groups (n =6 each): control group (group C), 2% bupivacaine group (group B2 ) and 4% bupivacaine group (group B4). The 18 pregnant rats were also randomly divided into 3 groups (n = 6 each): control group (group PC),2% bupivacaine group (group PB2 ) and 4% bupivacaine group (group PB4 ). Group C and PC received intrathecal (IT) normal saline 30 μl, and the other 4 groups received 2% or 4% bupivacaine 30 μl intrathecally. Analgesia was determined using the taifllick latency (TFL) before IT administration (baseline), and at 10 min, 20 min,30 min, 1 h, 2 h, 4 h, 1 d, 2 d, 3 d and 4 d after IT administtation. The percentage of the maximal possible effect (MPE) was calculated. Hind-limb motor function (MF) was also assessed. Results Compared with the baseline value, MPE at 10 min-2 h after administration and MF scores at 10 min-1 h after administration were significantly increased in group B2, MPE at 10 min-4 h after administration and MF scores at 10 min-1 h after administration were significantly increased in group B4;MPE at 10 min-1 d after administration and MF scores at 10 min2 h were significantly increased in group PB2 and MPE at 10 min-1 d after administration and MF scores at 10 min4 h were significantly increased in group PB4 ( P ＜ 0.05 ). Conclusion Pregnancy can enhance the potency of bupivacaine for spinal anesthesia in rats.

Objective To investigate the protective effects of magnesium sulfate on glutamate-induced neurotoxicity in cultured cochlear.Methods The cortis of newborn rats were cultivated in vitro. The cultured cochlear neurons were divided into glutamate group treated with 0.1 mmol?L-1 glutamate,magnesium sulfate group treated with different concentrations of magnesium sulfate(0.5,1.0,2.0 and 4.0 mmol?L-1) and combined group treated with glutamate and magnesium sulfate for 24 h. Immunofluorescence staining of Neurofilament 200kDa antibody was used to label spiral ganglion neuron(SGN) and the terminate of dendrites. The morphological changes of SGN were examined by fluorescent microscope and the amount of SGN was determined. In addition,the SGN was loaded with 10 ?mol?L-1 Fluo-3 /AM,and the intracellular Ca2+was measured by laser confocal scanning microscope (LCSM). Results Many SGN were smaller and swelling and vacuoles at the terminate of dendrites following glutamate treatment for 24 h. In combined group treated with glutamate and 0.5,1.0 and 2.0 mmol?L-1 of magnesium sulfate,the amounts of SGN increased compared with glutamate group(P
