OBJECTIVE:To discuss the laws applicable to the behavior of“drug handling beyond limits”.METHODS:The concerned contents of the related laws,codes,administrative rules and regulations issued at different time were analyzed comparatively.RESULTS:Under different laws and regulations,the same illegal behavior had different qualitations and treatments.CONCLUSION:Under the current laws and regulations,the behavior of“drug handling beyond limits”was qualitatively regarded as“drug handling without license”remains to be further consulted.

OBJECTIVE: To provide reference for the revision of the concept of drugs and regulations on non-medical substance used as medicines that stated in Drug Administration Law.METHODS: The existing legal defects were analyzed according to the difficulty related to the application of law in a administrative lawsuit case.RESULTS & CONCLUSIONS: The conception of drug stated in Drug Administration Law is not accurate and standard enough,which is unfavorable to define non-medical substance used as medicines as sham medicine.Drug Administration Law should be improved by drawing lessons from legislative reference of foreign countries.

OBJECTIVE:To analyze relevant regulations in Drug Administration Law and to study the safety of drug use. METHODS:The key points of the safety of drug use were analyzed through reasoning analysis. RESULTS&CONCLUSION:The safety of drug use was the core of medicine legislation while there were still some problems on law execution and blind spots in legislation. It is suggested to standardize the research and development of drug and purchase channel,improve system for safety of drug use and role of clinical pharmacists so as to guarantee the safety of drug use.

Objective To investigate the value of soluble triggering receptor expressed on myeloid cells-1(sTREM-1) in the diagnosis of bacterial pleural effusion. Methods The levels of sTREM-1 in pleural effusion were determined in 30 patients with bacterial pleural effusion, 33 patients with malignant pleural effusion,31 patients with tuberculous pleural effusion and 28 patients with transudate by quantitative ELISA assay. The levels of CRP in pleural effusion were assayed using immunonephelometry method. The diagnostic value was assessed by receiver operating characteristic ROC curve analysis. Results The levels of sTREM-1［(1255.2±248.6)ng/L］ in bacterial pleural effusion were significantly higher than those in malignant ［（125.6±22.4）ng/L］, tuberculous［（184.5±36.5）ng/L］ and transudate groups［（92.5±20.8）ng/L］ (P＜0.05). For ROC curve, when the cut off value of sTREM-1 was set at 425 ng/L, the sensitivity , specificity ,accuracy, positive predictive value and negative value was 93.3%,90.3%,91.9%,93.2% and 93.3%, respectively. Conclusions Detection of sTREM-1 in pleural effusion is helpful to differentiate pleural effusion of bacterial origin from those with other etiologies.

Objective To investigate the reversal effect and the mechanism of sodium norcantharidate(SNCTD)on human lung adenocarcinoma cell line A549/DDP. Methods CKK assay was used to screen out non-toxic concentration (less than 10 percent of cell inhibition ratio) of SNCTD, and to measure the IC50 of cisplatin and IC50 of innoxious concentration SNCTD plus cisplatin in drug-resistant cell line. The accumulation effect of Rh123 was assayed by flow cytometry after treatment with non-toxic concentration of SNCTD. PT-PCR was used to detect the expression of mdr1, MRP1 gene for the drug-resistant cell line treated with non-toxic concentration of SNCTD for 48h. Results (1)The non-toxic concentration of SNCTD was 5μg/ml. SNCTD could decrease drug resistance to cisplatin. The reversal fold was 1.97. (2)The fluorescence intensity of Rh123 in the cells treated with 5μg/ml SNCTD was obviously increased (F=36.99, P＜0.05). (3)The expressions of mdr1, MRP1 gene decreased significantly in a concentration-dependent manner.Conclusions SNCTD could reverse the resistance to cisplatin in A549/DDP cell line. It possibly downregulates the expression of mdr1, MRP1 gene, and inhibits the function of efflux pump of membrance protein.

Objective To discuss the characteristics, treatment method and prognosis of tibial tuberosity avulsion fracture in children. Methods From January 1995 to December 2007, there were 25 cases (23 boys and 2 girls). The age at injury ranged from 12 to 16 years(average 13.5 years). All cases were unilateral involved (10 of left, 15 of right). All of the injuries resulted from participation in athletic activities, 10 in basketball, 7 while jumping, and 8 in football game. According to the classification of Ogden, there were 1 type 1A, 4 type 1B, 5 type 2A, 7 type 2B, 4 type 3A, and 4 type 3B fractures. One type 1A fracture was treated nonoperatively with east immobilization, and other 24 fractures with open reduction and internal fixation. Results All of 25 cases were followed from 14 months to 7 years (average 43 months). The range of motion of knee joint was 0°-140° 3 months after operation, and all of them recovered to pre-injury levels of activity by 6 months after operation. According to Mosier clinical assessment system, the final outcome was evaluated as excellent in all. Wound healed primary, no compartment syndrome was found. The time of bony union ranged from 2 to 5 months, with the mean time of 3 months. No complications of infection, ex-tremities deformity and inner fixation failure were found. Conclusion The tuberosity avulsion fracture in children is an uncommon and special type of epiphyseal injury. These fractures occur in the narrow range of 13 to 16 years of age. The majority of patients are males, and most of them are unilateral involved. This in-jury has an excellent outcome without deformity or functional loss, once adequate reduction and fixation of fracture fragments have been achieved.

Purpose:To study the therapeutic effect of rhG-CSF upon the severe hypogranulocytosis of children with acute leukemia after intensive chemotherapy. Methods:After intensive chemotherapy, the comparison between the group with rhG-CSF treatment ( n =136) and the control group ( n =65) was made on the ANC dropping time, the incidence rate and the degree of severity of the infection.Results:The period of ANC ≥0.5?109/L was shorter in the group with rhG-CSF treatment than that in the control group ( P

Objective To investigate the value of CT pulmonary artery obstruction index (PAOI)in evaluating the severity in patients of pulmonary embolism (PE)by a correlation study between CT PAOI and right ventricular function parameters and arterial blood gas analysis index.Methods CT PAOI,right ventricular function parameters and arterial blood gas analysis index were collected from 70 patients with PE,who had received CT pulmonary angiography (CTPA)examination in our hospital.Spearman rank correlation coefficient was used to evaluate the correlation between the PAOI and right ventricular/left ventricular maximum short axis diameter ratio (RVd/LVd),main pulmonary artery diameter (MPAd),superior vena cava diameter (SVCd),arterial oxygen partial pressure (PaO2 ),arterial carbon dioxide into pressure (PaCO2 ),oxygen saturation (SaO2 ),Alveolar arterial oxygen partial pressure difference (P(A-a)O2 ).Results PAOI and PaO2 were negative correlation,the correlation coefficient was -0.442;PAOI and RVd/LVd, MPAd,SVCd,P(A-a)O2 were positively related,correlation coefficients ranged between 0.163-0.675;PAOI was not related to SaO2 .Conclusion CT PAOI can be used to evaluate the severity of PE,it is not consistent with the severity of the patient’s clinical condition.

OBJECTIVE: To study the activities of matrine and anti-tumor drugs on SPCA/I human lung adenocarcinoma cell line. METHODS: Suppression effects of different concentrations of matrine and matrine combined with anti-tumor drugs on lung cancer cells were measured by methyl thiazolyl tetrazolium (MTT) colorimetric assay. RESULTS: Different concentrations of matrine could inhibit the growth of SPCA/I human lung adenocarcinoma cells and there was a positive correlation between the inhibition rate and the drug concentration. Different concentrations of matrine combined with anti-tumor drugs had higher growth inhibition rate than anti-tumor drugs alone. CONCLUSION: Matrine has direct growth suppression effect on SPCA/I human lung adenocarcinoma cells and matrine combined with anti-tumor drugs shows a significant synergistic effect on tumor cells.
