OBJECTIVE:To investigate the characteristics and regularities of adverse drug reactions(ADR) induced by anti-infective drugs in our hospital.METHODS:657 ADR cases induced by anti-infective drugs collected by the ADR monitoring center in our hospital in 2006 were classified and analyzed.RESULTS:13 categories(49 kinds) of anti-infective drugs were involved in the total 657 ADR cases.Of which,those patients aged above 60 years accounted for 30.14%.The ADR were chiefly induced by quinolones,followed by cephalosporins and penicillins etc,which chiefly manifested as lesion of skin and its accessories(53.12%),followed by the lesions of digestive system and nervous system etc.CONCLUSION:Multiple factors contributed to the ADR,to which great importance should be attached so as to reduce the incidence of ADR induced by anti-infectives.

Objective To detect serum anti-Treponema pallidum specific antibody of 26 707 cases by Abbott I2000SR auto-matic chemiluminescent microparticle immunoassay analyzer,and treponema pallidum particle agglutination assay (TPPA) was regarded as a standard reference method which was used to detect anti-Treponema pallidum specific antibody.To analyze the false positive rate of Abbott I2000SR according to the TPPA.Methods Collected 26 707 serums from inpatients and outpatients of the hospital during September 1,2013 to March 5,2014.The subjects were asked to fasting conditions taking venous blood 3 ml,3 000 r/min centrifugal 10 min utes after the separation of serum,detected the Anti-TP by CMIA (Ab-bott I2000SR)and the TPPA testing,analyzed test results by statistical methods.Results There were 52 cases detected by I2000SR whose S/CO values of 26 707 cases of serum Treponema pallidum specific antibodies were 1 to 2,of which 9 cases were verified positive by TPPA,and the positive rate was 17.31%.There were 26 cases detected by I2000SR whose S/CO values of Treponema pallidum specific antibodies were 2 to 3,of which 9 cases were verified positive by TPPA,and the posi-tive rate was 34.62%.There were 26 cases detected by I2000SR whose S/CO values of Treponema pallidum specific anti-bodies were 3 to 5,of which 9 cases were verified positive by TPPA,and the positive rate was 34.62%.There were 25 cases detected by I2000SR whose S/CO values of Treponema pallidum specific antibodies were 5 to 7,of which 11 cases were veri-fied positive by TPPA,and the positive rate was 44%.There were 25 cases detected by I2000SR whose S/CO values of Treponema pallidum specific antibodies were 7 to 10,of which 17 cases were verified positive by TPPA,and the positive rate was 68%.There were 28 cases detected by I2000SR whose S/CO values of Treponema pallidum specific antibodies were 10to 13,of which 24 cases were verified positive by TPPA,and the positive rate was 85.71%.There were 23 cases detected by I2000SR whose S/CO values of Treponema pallidum specific antibodies were 13 to 17,of which 20 cases were verified posi-tive by TPPA,and the positive rate was 86.96%.There were 24 cases detected by I2000SR whose S/CO values of Trepone-ma pallidum specific antibodies were 17 to 21,of which 22 cases were verified positive by TPPA,and the positive rate was 91.67%.There were 29 cases detected by I2000SR whose S/CO values of Treponema pallidum specific antibodies were 21 to 26,of which 28 cases were verified positive by TPPA,and the positive rate was 96.55%.There were 104 cases detected by I2000SR whose S/CO values of Treponema pallidum specific antibodies were above 26,of which 104 cases were verified posi-tive by TPPA,and the positive rate was 100%.The total number of positive cases were 364,of which 254 were positive ca-ses,the positive rate was 69.78%.False positive rate was 0.42% and positive predictive value was 69.78%.Conclusion Abbott I2000SR automated chemiluminescent microparticle immunoassay analyzer has the feature of automated detection, closed reagents,simple operation,speed,and more accurate results and so on.Although high sensitivity but its results have false positive,so cannot diagnose based on the results of Abbott I2000SR,and need use of the TPPA to test and corroborate.

BACKGROUND: Pathological changes of pulmonary emphysema are not reversible according to the existent pathogenesis of pulmonary emphysema. Research over many years report that injury of pulmonary blood capillary may take part in new pathogenesis of pulmonary emphysema based on lung volume reduction operation and bronchial lumen occlusion. Mesenchymal stem cells (MSCs) have multi-directional differentiation potencies, such as the differentiation into vascular endothelial cells. Therefore, MSCs may promote pulmonary vascularization and repair pulmonary tissue.OBJECTIVE: To observe the effect of MSCs transplantation on pathological changes of arterial blood gas and pulmonary tissue in model rats with pulmonary emphysema, and investigate the therapeutic effects on MSCs on pulmonary emphysema and the pathogenesis of pulmonary emphysema.DESIGN: Randomized controlled animal study.SETTING: The Second Hospital of Shanxi Medical University.MATERIALS: Thirty healthy Wistar rats, 6 weeks old, of either gender, weighing 180-200 g. They were provided by Physiological Experiment Animal Center, Shanxi Medical University. All rats were randomly divided into MSCs treatment group, model group and control group with 10 rats each.METHODS: The experiment was carried out in the Physiological Laboratory of Shanxi Medical University from April 2005 to April 2006. Rats in the MSCs treatment group and in the model group were anesthetized and intratracheally perfused with 250 U/kg Porcine pancreatic elastase (PPE) to establish pulmonary emphysema models; while, rats in the control group were perfused with saline. The models were successfully established 4 weeks later. All rats were anesthetized and then femur and tibia were obtained to separate and culture MSCs in vitro. Immunocytochemistry was used to detect the expression of CD71 in order to evaluate MSCs. Bromium azacytidine-labeled MSCs were inserted along caudal vein into rats in the MSCs treatment group; while, rats in the model group and control group were inserted with the same volume of PBS solution.MAIN OUTCOME MEASURES: ① Changes of arterial blood gas in the three groups; ② Pulmonary tissue was used for pathological sections in order to calculate mean alveolar number, mean alveolar area and mean linear intercept; ③Immunocytochemical staining was used to measure numbers of CD34+ cells so as to determine proliferation of alveolar blood capillary.RESULTS: Three rats in all died during the model establishment, while another 3 rats were supplied. Therefore, an overall number of 30 rats were involved in the final analysis. ① Culture and evaluation of MSCs: At 3 days after inoculation, MSCs were generally adherent to walls and fusiformly shaped. In the third generation, the expression of CD71 was observed on the surface of MSCs.② Comparisons of arterial blood gas in the three groups: There were no significant differences in pH value, PO2, PCO2 and SaO2 in the three groups (P ＞ 0.05). ③ Pathological changes of pulmonary tissue: Pathological changes in the MSCs treatment group were milder than those in the model group;meanwhile, mean alveolar number in the MSCs treatment group was more than that in the model group, and there was significant difference between them (F=80.201, P＜ 0.05). While mean alveolar area and mean linear intercept in the MSCs treatment group were smaller than those in the model group, and there were significant differences (F =26.755,26.875, P ＜ 0.05). ④ Comparisons of CD34+ expression in pulmonary tissue: Relative positive area of CD34+ in the MSCs treatment group and model group was smaller than that in the control group (F =20.411, P ＜ 0.05), but that in the MSCs treatment group was larger than that in the model group, and there was significant difference between them (F=20.411, P＜ 0.05).CONCLUSION: MSCs can reverse the pathological changes of pulmonary emphysema; on the other hand, the decrease of the number of pulmonary capillary maybe one of the important pathogeneses of pulmonary emphysema.

Objective To investigate the protective mechanism of Salvianolic acid B (Sal B) on experimental in-vivo myocardial ischemia-reperfusion injury (MIRI)in rats. Methods Rats model of myocardial ischemia-reperfusion injury was induced by ischemia for 60 min and then reperfusion for 60 min. After treatment,endothelin (ET) levels in plasma and the homogenate of myocardial tissue,and serum levels of nitric oxide (NO) and NO synthase were measured. Meanwhile,the pathological changes of myocardial tissue were also observed. Results Compared with the model group,middle-dose and high-dose Sal B could depress the ET levels in the plasma and the myocardial tissue,and increase the content of serum NO and NOS (P

Objective To evaluate the effectiveness of using anti‐cyclic citrullinated peptide (anti‐CCP) antibody or rheumatoid factor(RF) as the single laboratory parameter for rheumatoid arthritis(RA) diagnosis ,versus to using the two parameters in com‐bination .Methods A total of 56 cases of patients with RA were enrolled into RA group ,other 34 cases of patients with out RA were enrolled into non‐RA group .Levels of anti‐CCP antibody and RF were detected by using electro‐chemiluminescence immunoas‐say(ECLIA)and compared between the two groups .And the diagnostic efficacy of single and combined detection of anti‐CCP anti‐body and RF were evaluated .Results The levels of anti‐CCP antibody and RF in the RA group were higher than those in the non‐RA group ,had statistically significant differences(P<0 .05) .In diagnosis of RA ,the areas under receiver operating characteristic (ROC)curve of anti‐CCP antibody and RF were 0 .925 and 0 .822 respectively .The sensitivity and specificity of anti‐CCP antibody were both higher than those of RF .Compared with single detection of anti‐CCP antibody ,there was no significant increase of sensi‐tivity in using anti‐CCP antibody/RF ,whereas the specificity dropped significantly .Combined detection of anti‐CCP antibody and RF ,compared with single detection of anti‐CCP antibody ,had significantly lower sensitivity ,but no significant changes were found in specificity .Conclusion Single detection of anti‐CCP antibody is more effective than RF for diagnosing RA ,while combined detec‐tion of anti‐CCP antibody and RF could not significantly improve the specificity and sensitivity .It is suggested to only use anti‐CCP antibody for diagnosis of RA .

Objective To study the pharmacokinetics of aristolochic acid A in Radix Aristolochiae and the compound preparation of Guanxinsuhe Capsule in mice in vivo after single-dose oral administration and observe the difference of aristolochic acid A absorption and distribution. Methods Aristolochic acid A assay was performed by RP-HPLC on a Waters apparatus with a DiamonsilTM C18 column (250 mm × 4.6mm, 5 μm), a mobil phase: a mixture of methanol-water-acetic acid (72: 27 : 1), flow rate: 1.0 mL/min, detection wavelength: 315 nm, and column temperature: 20 ℃. Results Mice were given Radix Aristolochiae and Guanxinsuhe Capsule by ig at the same level of 2. 5 mg/kg of aristolochic acid A, respectively, which were suspended in 0. 3% CMC-Na solution. Plasma concentrations were determined by RPHPLC. After single-dose ig administration of Radix Aristolochiae or Guanxinsuhe Capsule to mice, the mean plasma concentration-time courses of aristolochic acid A obtained fitted the one-compartment model.The main pharmacokinetic parameters of aristolochic acid A in Radix Aristolochiae, t1/2ka, t1/2 ke, tmax,AUC, Cmax are 5. 103 min, 43. 63 min, 17.89 min, 80. 45 (μg · min)/mL, and 0. 916 8 μg/mL; the rela tive pharmacokinetic parameters in Guanxinsuhe Capsule are 5. 294 min, 43.50 min, 18. 32 min, 33.08(μg · min)/mL, and 0. 381 8 μg/mL. Conclusion The Cmax of aristolochic acid A in Guanxinsuhe Capsule is significantly less than that in Radix Aristolochiae, which indicates that the compound compability could decrease the absorption of aristolochiae acid A.

Objective To evaluate the efficacy and complications of flexible ureteroscopy for the treatment of upper urinary tract calculi in children.Methods The clinical data of upper urinary tract calculi in 20 children including 16 male and 4 female,treated by using flexible ureteroscopy,were collected from January 2014 to May 2015 in the First Affiliated Hospital of Zhengzhou University.The mean age was 6.4 years (ranging from 2.7-15.0 years old).Among them,6 cases had upper ureteral calculi and 14 cases had renal calculi.All the calculi was found unilaterally with on the left side in 12 cases and on the right side in 8 cases.Ipsilateral mild to moderate hydronephrosis were found in all of the cases.The mean stone size was 1.2 cm (ranging from 0.5-1.8 cm).All the cases were treated through retrograde flexible ureteroscopy holmium laser lithotripsy after the invalid conservative through conservative treatment.Double J tube was left routinely in the sick side 1 week before operation to expand the internal diameter of the ureter.A double J stent was left in place for 1 month after operation as a routine.Results The flexible ureteral access sheath failed to insert into the upper ureter in 2 cases because of the narrow ureter,then the flexible ureteroscopy was inserted into ureter through wire directly.The flexible ureteral access sheath was successfully inserted into the ureter for the others and flexible ureteroscopy were inserted through flexible sheath.The mean operative time was 38 min (ranging from 20-60 min).The patients were discharged from hospital after a mean of 4.5 days (ranging from 3-7 days).The rate of stone-free in one-stage was more than 90％.There were residual small stones in the lower calices of kidney in 2 cases.The perfusion liquid volume during the operation was 500 mL(ranging from 200-1 000 mL).There was no major perioperative complication,while transient macroscopic hematuria and fever were common complications after operation.The stone search was performed successfully in the whole 14 cases.NO residual stone could be found through ultrasound and kidney ureter bladder plain and Double-J stent was removed 1 month after operation.Conclusions Flexible ureteroscopy produces high stone-free rate and clinical safety for upper urinary calculi in children.However,the complications of flexible ureteroscopy lithotripsy cannot be ignored and sufficient preoperative preparation and careful perioperative safety control should be required.

Objective To investigate whether octreotide,as somatostatin analogue,can enhance the sensitivity of the human lung adenocarcinoma cell line A549 to chemotherapeutic drugs.Methods Different concentration of octretide,cisplatin and 5-Fluorouracil (5-Fu) was respectively acted on the lung adenocarcinoma cell line A549.The absorbance value was tested by colorimetry through MTT method to evaluate the effect of octreotide,cisplatin,5-Fu or the three drugs combined respectively after 48 hours.Each drug concentration had six holes and it repeated three times.The effects of combination therapy was analysed with isobologram.Results It was proved that octreotide could inhibit the proliferation of A549 cells in a dose-dependent manner at the concentration range of 1.3 mg/L ～ 166.7 mg/L.The inhibition rate was dose-dependent which was higher when octreotide combined with cisplatin and 5-Fu than it alone.It has statistically significant difference (P ＜ 0.05 ).The effect plots of IC50 were located in the synergy areas of isobologram.Conclusion It can be concluded that octreotide could inhibit the proliferation of A549 cells in vitro.This inhibition enhances when octreotide is combined with cisplatin and 5-Fu.Octreotide can enhance the susceptibility of A549 cells to cisplatin and 5-Fu.
