By non-steady method,the effective diffusivity of ferrous sulphate within alginate calcium gel entrapped without bacteria was measured.Meanwhile the oxidation ability of entrapped bacteria was analyzed.Experimental results showed that the effective diffusion coefficient of ferrous sulphate decreased with the increase of alginate concentration,the optimum alginate concentration is 2%(W/V).The effect of calcium chloride on the effective diffusivity was neglectable.The incubation of ferrooxidans would pass through 10 hours,and the diffusion coefficient within gel entrapped Thiobacillus ferrooxidans cells was less remarkably than that of ferrous sulphate without entrapped cells.For the entrapped cells,the absolute oxidation time was shortest and the rate change was fastest with the initial Fe concentration 5g/L.The absolute oxidation time was same when the initial Fe concentration was 8g/L and 10g/L.

One kind of new cefazolin sodium hydrate crystal was obtained in the isopropyl alcohol - water system. There are two symmetry independent molecules in the asymmetric unit, both being well ordered in the lattice, and ten independent water positions but generally four to six (mean five) water molecules and one sodium ion present in the unit cell structure. Huge solvent tunnels can be found. Again there are two general regions of water molecules, those in the large solvent tunnels and those in proximity of the sodium ion and the tetrazole moieties of the drug molecule. The physical and chemical characteristics of the new cefazolin sodium hydrate crystal are similar to that of the alpha-form cefazolin sodium crystal, and the new crystal has better chemical stability than amorphous cefazolin sodium powder.

OBJECTIVE: To access application value of multi-slice spiral computed tomography (MSCT) and coronary artery calcium scoring (CACS) in investigation the coronary artery disease (CAD), and to explore the effective way of virtual autopsy to evaluate the sudden death due to CAD. METHODS: Nine cases of sudden cardiac death were collected to analyze MSCT before the autopsy. The quantitative analysis of the degree of coronary artery calcium was made by Agatston's method. The CACS of all the subjects were calculated based on the diagnostic criteria for CAD, in which calcium scoring was more than 400. The results of CACS were compared with that of the autopsy. RESULTS: Only 2 cases got the high calcium scoring which were more than 400 in the 9 cases died of CAD confirmed by the autopsy. The prediction rate of CACS for CAD was only 22.2%. Pulmonary edema of different severity was found in both autopsy and MSCT. There was a higher morbidity rate in the left anterior descending of coronary artery than the other branches. CONCLUSION Obvious calcification of coronary artery can be detected by MSCT and calculating CACS. To detect subtle calcification needs other technologies such as postmortem angiography.

This study is to investigate the effects of sophoridine on NF-kappaB signaling pathway in kidney tissue of endotoxemia mice and the mechanism involved. BALB/c mice were challenged with lipopolysaccharide (LPS) caudal vein injection, then sophoridine was administered by intraperitoneal injection. Totally 50 mice were divided into 5 groups: control group, LPS model group, sophoridine treatment 12 mg x kg(-1) group, 6 mg x kg(-1) group and 3 mg x kg(-1) group. All animals were sacrificed at 6 hours after treatment. Kidney and blood samples were harvested. IKKbeta mRNA and TNF-alpha mRNA expression of renal tissue was measured by the reverse transcription polymerase chain reaction (RT-PCR), and phosphorylation IKKbeta protein (pIKKbeta) was detected by immunohistochemistry. NF-kappaB P65 protein expression and distribution of renal tissue were observed by Western blotting and immunofluorescence laser confocal microscopy. Serum TNF-alpha level was detected by radioimmunoassay. The results showed that the sophoridine significantly reduced the expression of IKKbeta mRNA and pIKKbeta protein, and inhibited the expression of NF-kappaB P65 protein and decreased the entry nuclear rate of NF-kappaB P65 in the renal tissue of endotoxemia mice. Thereby the renal TNF-alpha mRNA expression and serum TNF-alpha level were significantly reduced. These results suggest that sophoridine could inhibit inflammatory reaction induced by LPS through inhibiting activation of NF-kappaB signaling pathway.

Objective To study the pharmacokinetics of omeprazole tablets in Chinese Hui and Han healthy volunteers.Methods Twenty volunteers were involved in the study,including ten Chinese Hui volunteers and ten Han volunteers.Each healthy volunlteers were given asingle oral dose(40 mg)of omeprazole tablet.The concentration of omeprazole in plasma was determined by RP-HPLC and the pharameters were calculated by DAS 2.0 software.Results The main pharmacokinetic parameters of Chinese Hui and Han were as follows:C_(max) were (941.94±446.08) and (760.49±581.23) μg·L~(-1);t_(max) were(2.7±0.68)and(2.70±0.82)h;t_(1/2) were(2.43±2.83)and(1.60±1.28)h;AUC_(0-12) were (2.29±1.12)and(1.44±7.98)mg·h·L~(-1);AUC_(0-∞) were (2.33±1.11)and(1.47±7.69)mg·h·L~(-1),respectively.Conclusion Individual difference is significant in C_(max),AUC_(0-12),AUC_(0-∞) after an oral omeprazole,but the pharmacokinetic parameters obtained from the results of ststistical analysis show no significant difference in the main pharmacokinetic of omeprazole between Chinese Hui and Han.

Objective To explore the effect of improved new mask in noninvasive positive pressure ventilation sputum suction.Methods Among the patients with chronic obstructive pulmonary disease and type Ⅱ respiratory failure,78 patients were selected and divided randomly into observation group (n =38 ) and control group (n =40).Both groups implemented the noninvasive ventilation and symptomatic treatment.The endotracheal suction tube was left in patients for 96 hours,the end of which passes the junction part of the mask and the face.For the control group,the process of ventilation was interrupted for sputum suction,while for the observation group; the process of ventilation kept on without interruption due to the side hole on the mask for suction.In the interval of sputum suction,the same airway humidification fluid was injected into the suction tube regularly for both groups.Results When the observation group and the control group had accepted the noninvasive ventilation simultaneously for 24 hours,the oxygen and carbon dioxide partial pressure difference was not statistically significant(t =0.84,1.07;P ＞ 0.05).While for 48 hours,the oxygen and carbon dioxide partial pressure difference was statistically significant [ (61.53 ±9.94) mm Hg versus (56.57 ± 11.19) mm Hg,t =2.07,P ＜ 0.05 ; (64.02 ± 10.37 ) mm Hg versus ( 69.55 ± 12.73 ) mm Hg,t =2.10,P ＜ 0.05 ].and for 96 hours,the oxygen and carbon dioxide partial pressure difference was also statistically significant [ (69.35 ±9.37) mm Hg versus (60.57 ± 10.64) mm Hg,t =3.87,P ＜ 0.01 ; ( 55.82 ± 10.58 ) mm Hg versus ( 61.55 ±11.73 ) mm Hg,t =3.03,P ＜ 0.01 ].The difference of the time it took for the patients to got conscious in both groups was statistically significant[ (21.21 ±7.24) h versus (25.35 ±9.28) h,t =2.17,P ＜0.05].The difference of the number of cases with the application of invasive ventilation in the end of two groups was statistically significant (x2 =4.78,P ＜ 0.05 ).The difference of the total time with the application of positive ventilation of two groups was statistically.significant [ ( 152.23 ± 25.91 ) h versus ( 169.57 ± 33.49 ) h,t =2.54,P ＜ 0.05 ].Conclusions The mask with a side hole for sputum suction and endotracheal suction tubes can be applied to the patients of the chronic obstructive pulmonary disease combined with the Ⅱ respiratory failure.Without the interruption of the noninvasive ventilation,sputum suction has significant reduction in complications,and the patients can have a shorter recovery time,better treatment effect,and smaller rate of invasive ventilation.

OBJECTIVETo study the etiological agent of hand-foot-and-mouth disease (HFMD), and to genetically characterize enterovirus 71 (EV71) isolated from clinical specimens of HFMD patients in Nanjing in 2010.

METHODThroat swab specimens were collected from 248 inpatients with HFMD in Nanjing Children's Hospital and then viral isolation was performed. Real-time PCR was used for detection of EV71, coxsackievirus A16 (Cox A16) and other enteroviruses from the positive isolates. Twenty EV71 strains from different clinical types of cases were selected for entire VP1 coding gene amplification and sequencing, finally a phylogenetic tree was constructed among the 20 EV71 strains and EV71 representative strains of known genotypes and subgenotypes.

RESULTFrom the 248 throat swabs specimens, 110 EV71 strains, 28 Cox A16 strains, and 8 other enterovirus strains were isolated and the positive rate was 44.35%, 11.29%, 3.23%, respectively. Then nucleotide sequencing was performed on the 20 EV71 strains. There was little difference in the nucleotide and the amino acid sequences among the 20 EV71 strains, the homology was 95.51%-100% and 98.32%-100%, respectively. The phylogenetic tree showed that all the 20 EV71 strains belonged to C4 subgenotype.

CONCLUSIONEV71 was the main pathogen of HFMD in Nanjing in 2010 and all the analyzed isolates belonged to C4 serotype. No significant difference was found in sequence of VP1 region of EV71 isolated from different clinical types of cases.
