OBJECTIVE:To analyze the characteristics and rules of pediatric adverse drug reaction (ADR) in our hospital, and provide reference for clinical safe drug use. METHODS:Retrospective study was adopted to statistically analyze the ADR re-ports in our hospital from Mar. 2012 to Jun. 2016. RESULTS:In the 176 ADR reports,102 were male(57.95%)and 74 were fe-male (42.05%);children younger than 6 years old had the highest incidence of ADR (81.26%);intravenous administration in-duced 153 cases(86.93%),the top one was antibiotics,which involving 20 antibiotics,totally 106 cases(60.23%);skin and its appendages damage were the main manifestations, totally 127 cases (50.60%). CONCLUSIONS:Pediatric ADR monitoring should be strengthened,dinical rational drug use should be promoted by cooperation in many ways to reduce and prevent the incid-erle of pediatric ADR.

Purpose:We evaluated the sensitivity and specificity of p53 antibodies (p53-Ab) as a preoperative tumor marker and as a prognosis marker in colorectal cancer patients and we also investigated whether p53-Ab production is dependent on p53 protein overexpression in tumor tissue.Methods:Serum samples from 178 colorectal cancer patients and 40 healthy controls were tested for the presence of p53-Ab by using an ELISA kit. Expression of p53 protein in tumors was determined using mouse anti-human p53-Ab.Results:Serum p53-Ab was detected in 18.54% of patients while all controls were negative. A strong correlation between p53-Ab production and p53 protein expression was observed: 69.7%of p53-Ab positive cases had tumors positive for p53 vs 30.3%of p53-Ab negative cases. There was also a significant predominance of p53-Ab positive cases in Dukes ’ stages B (16/71,22.54%), C (12/55,21.82%)and D(5/30,16.67%)over stage A. No difference in patients’ age, sex and localization was found between the p53-Ab positive and negative groups. Recurrence of cancer did not differ between p53-Ab positive and negative patients after a median follow-up of 13.5 months and also median survival time did not vary significantly.Conclusions:There was a significant correlation between p53-Ab production in serum and p53 protein expression in tumor tissue. Because of their low sensitivity (18.54%) p53-Ab are not suitable as a preoperative tumor marker. However, their high specificity (100%) and their potential for early diagnosis of a tumor relapse makes them valuable for postoperative monitoring during follow-up in p53- Ab positive patients.[

Objective To detect CK-19 mRNA expression by quantitative real-time RT-PCR in axillary drainage fluid of rectal cancer and investigate its clinical significance.Methods Axillary drainage fluids were collected from 59 patients with rectal cancer and 15 patients with benign abdominal lesion from Sep.2010 to Dec.2010.Level of CK-19 mRNA in axillary drainage fluid was detected using specific primers by real-time RTPCR.The data were statistically analyzed to investigate the relationships between CK-19 mRNA level and tumor invasion,lymph node status,tumor stage and tumor differentiation level.Results The positive rate of CK-19 mRNA expression in patients with rectal cancer was 67.8％,which was significantly higher than that in patients with benign abdominal lesion.The expression of CK-19 mRNA was significantly correlated with the depth of tumor invasion,lymphnode status,tumor stage and histopathological differentiation( P ＜ 0.05 or P ＜ 0.01 ).Ck129 mRNA expression was associated with the pathological level,the higher of the lymph node translation level,the higher expression in the axillary drainage fluid after rectal cancer surgery (r =0.674,P =0.021 ).The lower of the lymph node differentiation level,the higher expression in the axillary drainage fluid after rectal cancer surgery (r =-0.741,P =0.014).Conclusion Quantitative detection of CK-19 mRNA in axillary drainage fluid of rectal cancer by RT-PCR could enhance the diagnostic sensibility of colorectal cancer micrometastases.RT-PCR assay is suitable for predicting peritoneal micrometastasis of rectal cancer,which is a reference for postoperative treatment and prognosis prediction.

Objective To assess the tolerance of preoperative carbohydrate-rich beverage,to determine its effect on postoperative insulin resistance and analyze its potential mechanism.Methods Thirty-two patients undergoing elective colorectal cancer resection were recruited to this randomized controlled study and assigned to two groups at random.Patient in control group was fasted before operation,while patient in study group was given oral water.Homeostasis model assessment(HOMA)indexes,activity of PTK,and mRNA and(or)protein expressions of PKB,PI3K and GluT4 were measured before and(or)immediately after surgery.Furthermore preoperative well-beings of patients were studied.Results Among well-beings,feeling of thirst,hunger and anxiety tended to be better in patients receiving carbohydrate-rich beverages compared with fasted ones(P0.05).Conclusion Preoperative consumption of carbohydrate-containing fluids is safe and effective.Provision of carbohydrate energy source prior to surgery may attenuate immediate postoperative insulin resistance.A carbohydrate-rich drink enhances insulin action at the time of onset of anaesthesia or surgery by activating three kinases named PTK,PI3K,PKB which are key enzymes in pathway of insulin signal transduction.It is likely to explain the effects on postoperative insulin resistance.

Suturing is the key to the success of corneal transplant surgery.By analyzing the suturing-process of corneal,a model for suturing was established.A suturing theorietical trajectery was proposed without considering the viso-elasticity of comeal.Then,a suturing simulation was done with the ANSYS software,the manipulating trajectory was planned for corneal soft-tissue with viso-elasticity,correspondingly,and the position and posture of needle in suturing were obtained.The study can be used for suturing manipulation in cornea suture surgical.

Objective To assess the prognostic values of the immunohistochemical expression of vascular endothelial growth factor (VEGF) and vascular endothelial growth factor receptor-2 (VEGFR-2) in a cohort of patients with operable advanced laryngeal cancer who have been treated with induction chemotherapy. Methods VEGF and VEGFR-2 expression in the Forty-nine patients was quantified by an enzyme immunosorbent assay in a retrospective series.Results The moderate to high VEGF expression in 34 patients were found and low expression in 15 patients. VEGFR-2 expression was moderate to high in 31 patients and was low expression in 18. The probability of a complete response to induction chemotherapy was significantly higher in patients with none to low VEGF expression.Conclusion VEGF expression seems to be a significant predictor of complete response to induction chemotherapy.

Objective To explore the relationship between the expression of Ki67 and mitosis karyorrhexis index（MKI）in ganglioneuroblastoma（GNB）.Methods Clinical materials and histology slides from 28 patients with GNB were reviewed.MKI was counted under microscope and the expression of Ki67 protein in GNB was evaluated by immuohistochemical technique.The follow-up data were also collected and statistically analyzed.Results There were 15 patients with favourite prognosis（favourite subgroup,FS） and 13 patients with poor prognosis（unfavourite subgroup,US）.The survival time of GNB patient in FS was significantly longer than that in US（P 0.05）.The survival time is related to pathology classification（P 0.05）.MKI was correlated with advanced clinical stage,pathology classification and survival time（P 0.001）.No significant difference in Ki67 expression was found between low and high MKI patients.Conclusion MKI might be a reliable prognostic parameter for making diagnosis and evaluating prognosis of GNB.Detection of Ki67 expression might be not useful for evaluating the prognosis of GNB.

Objective To investigate the relationship between single nucleotide polymorphisms (SNPs) of PRKCG gene (rs2547362,rs3745406) and osteosarcoma susceptibility in the osteosarcoma patients and the normal population.Methods Sixtyone patients with osteosarcoma who had been admitted in our hospital from January 2011 to December 2012 and 63 healthy adults were enrolled in this study.A 2-ml peripheral blood sample was taken from each participant.The RT-qPCR method was used to detect the genotype and allele frequency distribution of PRKCG gene at rs2547362 and rs3745406 in osteosarcoma patients and normal population.Osteosarcoma patients were divided into several groups according to the clinical parameters such as age,gender,histology,tumor location,Enneking classification,tumor metastasis and therapy,and then we analyzed the relations between the genetic polymorphism and clinical parameters.Results 1) The genotype of PRKCG gene at rs3745406 included CC,CT and TT.The differences of genotypes (CC,CT,TF) and alleles (C,T) frequency distribution at rs3745406 were not statistically significant between osteosarcoma patients and the normal population (P=0.490,P=0.554).2) The genotype of PRKCG gene at rs2547362 included CC,CT and TT.The differences of genotypes (CC,CT,TT) and the alleles(C,T) frequency distribution at rs2547362 were statistically significant between the osteosarcoma patients and the normal population (P=0.006,P=0.007).3) The differences of genotypes (CC,CT,TT) and alleles (C,T) frequency distribution at rs3745406 were statistically significant between patients with metastasis and patients without metastasis (P=0.000,P=0.000).The CT and TT genotypes and the T allele carrier frequency at rs3745406 were higher in patients with metastasis than in patients without metastasis.SNPs at rs2547362 were not associated with clinical parameters.Conclusion The genetic polymorphism of PRKCG gene at rs2547362 is associated with osteosarcoma susceptibility.The TT genotype and T allele at rs3745406 are associated with metastasis of osteosarcoma,which may be a risk factor for metastasis in the osteosarcoma patients.

Objective:To assess the role of EGFR mutations on pemetrexed response in patients with advanced lung adenocarcino-ma. Method: Forty pulmonary adenocarcinoma patients with evaluable lesions were retrospectively screened .They had been treated with pemetrexed-included chemotherapy and had EGFR gene test results. The evaluation endpoints were overall response rate,disease control rate and progression free survival. Result:No significant statistical difference was seen in overall response rate(ORR) (44.4%VS 31.8%, respectively) and disease control rate(DCR) (88.9%VS 81.8%, respectively ) between EGFR wild group and EGFR muta-tion group, but patients in EGFR wild group had longer progression free survival(PFS) ( 8.9 months VS 5.3 months;P=0.046). Conclu-sion:EGFR mutation status can influence the efficacy of pemetrexed.
