OBJECTIVE:To analyze clinical influencing factors and monitoring results of serum concentration of digoxin (SDC) to provide reference for rational use of drug. METHODS: 137 medical records were collected and analyzed statistically with multiple regression analysis in order to study the relationship of SDC with influencing factors. RESULTS: SDC was significantly affected by dosage, height, body weight, free fat body weight, body surface area, creatinining clearance rate, serum creatinine (P

Objective To investigate the CT features of desmoplastic small round cell tumor (DSRCT)occurred in abdomen and pelvis.Methods The CT images of 4 patients with pathologically proven DSRCT occurred in abdomen and pelvis were retrospectively analyzed.Results The CT features common to the 4 DSRCT in abdomen and pelvis were as follows:the lobulated soft-tissue masses were very large;the masses often involved omental and serosal surfaces of abdomen and pelvis organ and had close relationship to the surrounding organs;the originating site of the tumors were not apparent;intratumoral hemorrhage or necrosis were often present;and contrast-enhanced CT scan showed mild to medium heterogeneous enhancement.Conclusion The CT features of DSRCT in abdomen and pelvis are rather specific and can provide helpful information to the clinical diagnosis.

Objective To explore the diagnostic value of serum miRNA-182 in colorectal cancer(CRC).Methods A total of 53 CRC patients were enrolled in this study,serum miRNA-182 was detected by quantitative real time polymerase chain reaction(qRT-PCR).The results were compared with those of patients with benign intestinal diseases and healthy controls.Results The content of serum miRNA-182 in CRC patients was significantly higher than those in patients with benign intestinal diseases and healthy group(P<0.05).The ROC curve showed that the area under the curve of serum miRNA-182 was 0.846,the confidence interval was 0.768-0.925,the diagnostic sensitivity was 77.1%,and the specificity was 81.1%.Serum miRNA-182 levels were correlated with TNM stage(P=0.011) and distant metastasis(P=0.002) in patients with CRC,but no significant correlation with other clinical parameters(P>0.05).Serum miRNA-182 level in CRC patients after surgery was significantly lower than that before operation(P<0.01),and which was significantly higher in patients with recurrence/metastasis after surgery(P=0.019).Conclusion Serum miRNA-182 level increased significantly in CRC patients,and which was closely related to the disease and malignant progression,serum miRNA-182 could be used as a potential marker for clinical diagnosis and disease evaluation of CRC.

Objective To investigate the dose-response and its mechanisms of preventive effect of 103 Pd radioactive stent on restenosis in rabbits after balloon injury. Methods The abdominal arteries of the rabbits randomized into common or radioactive stent groups (including 5 Gy, 15 Gy, 25 Gy, 35 Gy groups) were balloon injured, and then stented. Intravascular ultrasound and angiography on abdominal arteries, immunohistochemical study of PCNA, and TUNEL assay were performed 8 weeks after stenting. Results Both the minimal lumen diameters and in-stent lumen areas in 103 Pd radioactive stent groups [(1.94?0.21) mm and (5.99?0.43) mm2, (2.17?0.12) mm and (7.01?0.93) mm2, (2.43?0.22) mm and (8.09?0.89) mm2, (2.56?0.27) mm and (8.49?0.54) mm2 in turn in 5 Gy, 15 Gy, 25 Gy, 35 Gy groups, respectively]were significantly improved with increases of the doses at the end of 8 weeks,revealing a dose-response effect. The positive ratio of PCNA in each 103 Pd stent group was reduced as compared with that in commen stent group (P

Due to its effectiveness and specificity,RNA interference (RNAi) technology is widely used in the treatment of tumor,viral infectious and metabolic diseases.Noninvasively tracing the delivery of therapeutic RNA molecules in vivo and evaluating the therapeutic effects are important to promote the clinical application of RNAi technology.Molecular imaging allows noninvasive visualization of biological processes at the cellular and molecular level in vivo.It can be used to monitor the biodistribution of therapeutic RNA molecules and to assess the effects of the RNAi.This article reviews the advance of molecular imaging in monitoring the delivery of RNAi molecules and evaluating the therapeutic effects of RNAi.

Objective To know the pollution situation by microcystin MC in Tai Lake in Wuxi. Methods The MC content in 12 water samples and 28 fish samples in the Tai Lake were determined by ELISA. Results The positive rates of MC in water samples and fish samples were 100%. The mean content of MC in water samples was higher in July 9 874.8 pg/ml than in November 142.8 pg/ml. The mean content of MC in the livers was 27.84 ng/g, in the muscle it was 3.97 ng/g. Conclusion The Tai Lake has been contaminated by microcystin and it can be detected in the fish living in the lake.

1:1,and fat emulsion's energy delivery exceeding 50% of total non -protein calories.CONCLUSION: It' s high time to set up a parenteral nutrition support team, enabling clinical pharmacists to assist physicians with the regulation of PN support in parenteral nutrition dispensing.

The molecular targeted therapy method using microRNAs(miRNAs)is gradually stepping into people′s vision. miRNAs affect colorectal cancer progress via abnormal expression in tumor cells or micro-environment. The high or low expressions of miRNAs in specific tissues probably have an impact on the expressions of oncogenes,tumor suppressor genes or other aspects including the surrounding environments,the metastases and the drug tolerance of tumors,thus contributing to curing the colorectal cancer. Nowadays, miRNA has entered the stage of animal experiments.

Objective To investigate the incidence and the drug-sensitivity results of mycoplasma infection in genital tract from the gynecological outpatients,in order to provide a laboratory evidence for clinical rational use of drug.Methods The drug sensitiv-ity kit was used for isolation and culture of mycoplasma,reproductive tract secretions samples of 1 067 cases of gynecological pa-tients were collected to do mycoplasma identification and drug sensitivity test.Results In 1 067 samples,the positive rate of myco-plasma were 659 samples,including ureaplasma urealyticum(Uu)positive rate was 72.99%(481/659),mycoplasma hominis (Mh) positive rate was 3.79%(25/659),Uu and Mh positive rate accounted for 23.22%(1 53/659).The drug sensitivity results of 12 kinds of antimicrobial agents showed that single infection Uu was more sensitive to josamycin,doxycycline,minocycline,tetracy-cline,clarithromycin,azithromycin and roxithromycin.Single infection Mh was more sensitive to doxycycline,josamycin,minocycline and tetracycline.Mixed infection of Uu and Mh was more sensitive to josamycin,minocycline and doxycycline.Conclusion The main pathogen isolated from patients infected with plasma in our hospital is Uu,whether single Uu or Uu,Mh mixed infection,there are differences in the sensitivity of antimicrobial,clinicians should use drug rationally according to the conditions of patients and drug sensitivity results to reduce drug resistance rate.

Objective To compared the effect of combined teaching method of lecture,case analysis and GasMan@software (LAG) and traditional teaching method (LBL) in inhalation anesthesia practice course.Method 78 anesthesiological undergraduates were randomly assigned to G group (n=39) or Control group (n=39).According to the requirements of clinical anesthesiology in the syllabus,G group used classroom lectures,case analysis and GasMan@software (LAG) teaching method,while Control group used lecture based learning (LBL) teaching method.The students took anonymous quiz and filled teaching effect evaluation form after practice course.Then the exam results were compared between groups to evaluate the teaching effect.SPSS 19.0 was applied to do statistical analysis and t test and x2 test were used.Results Compared to the Control group,G group got better results in objective questions like choosing,judgment,case analysis and average ranks (P=0.000),and there was no significant difference in the identification section (P=0.087),while G group also got better results in subjective questions like learning interests,study efficiency,memorize,logical thoughts,ability of analysis,solving problems and cooperation (P＜0.05).Conclusion Compared to traditional teaching method,the combined use of lecture,case analysis and GasMan@software make students immersive,develop their clinical thinking ability,and improve the teaching effect of inhalation anesthesia practice course significantly.
