The irrational drug use is one of the major public health issues. As children are in growth, their drug absorption, distribution, metabolism, excretion and pharmacodynamic characteristics are different from those in adults, thus more challenges on how to make rational use of drugs in children are seen. In this paper, by analyzing current situation of irrational drug use in children, the definition and standards of the rational drug use, and the measures adopted by WHO and China in promoting rational use of drugs in children, we emphasize here and call for a promotion of the awareness of rational use of drugs in children, and activities in forms of propaganda and health education, popularization of medical science and the medication safety knowledge, guidance for the development of good medication beliefs and habits in public, improvement of the social security administration, maximization of the protection of children's medication safety, and maintenance of children's health rights and interests.

Objective To determine the clinical indicators of early death (within 72 hours) in patients with acute paraquat poisoning.Methods The data of 93 acute paraquat poisoning patients admitted to emergency intensive care unit (EICU) of the First Hospital of China Medical University were retrospectively analyzed.The patients were divided into two groups according to whether they died within 72 hours or not.The gender,age,poison dose,paraquat concentration in urine,reduction of paraquat amount in urine after each hemoperfusion,and the worst value of white blood cell (WBC) count,lymphocytes count,arterial blood gas analysis,blood K +,Na+,Cl-,and serum amylase,serum lipase,serum total bilirubin,troponin Ⅰ,creatine kinase (CK),blood urea nitrogen,serum creatinine within 24 hours after poisoning were compared.Spearman correlation analysis was used to analyze the correlation between paraquat concentration in urine and the dose of paraquat.The predictive value of each indicator at death in early stage of poisoning was analyzed with receiver operating characteristic curve (ROC curve).Results Nineteen patients in the group of those died in early stage of poisoning (within 72 hours) resulted in a mortality rate of 20.4％.Compared with non-early death group,in early death group,the value of poison dose (mL:133.4 ± 108.8 vs.58.6 ± 40.0,t=3.145,P=0.002),paraquat concentration in urine [mg/L:16.34 (11.87,96.76) vs.4.46 (1.21,12.78),Z=-3.422,P=0.001],WBC (× 109/L:22.63 ±9.72 vs.14.95 ±8.39,t=3.446,P=0.001),blood lactate [Lac (mmol/L):6.7 (2.2,12.1) vs.1.9 (1.1,3.4),Z=-3.294,P=0.001] were significantly higher,and the reduction rate of paraquat concentration in urine after first perfusion [(38.4 ± 15.63)％ vs.(67.59 ± 27.87)％,t=2.945,P=0.004] and arterial partial pressure of carbon dioxide [PaCO2 (mmHg,1 mmHg=0.133 kPa):28.7 ± 9.3 vs.34.8 ± 6.7,t=-3.245,P=0.002] were significantly lowered.There was no significant difference between two groups in other indexes.Poison dose and paraquat concentration in urine showed significantly positive correlation (r=0.450,P＜0.001).ROC curve showed that the predictive value of paraquat concentration in urine,WBC,and Lac in early death were significant [area under the ROC curve (AUC) of paraquat concentrations in urine was 0.806,95％ confidence interval (95％CI) 0.699-0.913,the cut-off value was 11.64 mg/L,with sensitivity 84.6％,specificity 71.4％; AUC of WBC was 0.734,95％CI 0.569-0.899,the cut-off value was 15.94 × 109/L with sensitivity 69.2％,specificity 76.8％ ; AUC of Lac was 0.729,95％CI 0.568-0.891,the cut-off value was 1.95 mmol/L with sensitivity 84.6％,specificity 42.9％].Conclusions Paraquat concentrations in urine,WBC,Lac,poison dose and PaCO2 were the risk factors of the early death of the acute paraquat poisoning.The research suggests that paraquat concentration in urine,WBC and Lac are valuable in predicting early death of the patients.

Objective To investigate the protective effect of antihypertensive drug NO.1 on brain cortical tissue in spontaneously hypertensive rats.Methods A total of 60 spontaneously hypertensive rats (SHR,30 males and 30 females) and 12 healthy Wistar rats (6 males and 6 females) weighed (200 20) g,were randomly divided into 6 groups.Model group (SHR,n=12) and control group (healthy Wistar rats,n=12) were given the same dose of placebo.Captopril group (SHR,n=12) were given captopril 5 mg · kg-1 · d-1.The low-,median-and high-dose groups of antihypertensive drug NO.1 were given 0.25,0.5 and 1 g · kg 1 · d-1 respectively.After 4 weeks of treatment,carotid artery blood pressure was detected.All rats were sacrificed,and brain tissue samples were taken.The expressions of Bcl-2,Bax,necrosis factor NF-κB P65,chloride channel 2 and 3 (CLC-2 and CLC-3) were determined by RT-PCR and Western blotting.Results After 4 weeks of antihypertensive NO.1 treatment,SHR carotid artery blood pressure was (182.8 ± 7.3)mmHg in low dose group,(170.3±9.4) mmHg in medium dose group,and (163.9±10.6) mmHg in high dose group; and (205.4 ± 11.3)mmHg in the model group.Antihypertensive drug NO.1 significantly reduced blood pressure in spontaneously hypertensive rats,and had a concentrationresponse relationship (P＜0.05).Antihypertensive drug NO.1 decreased the expressions of Bax,CLC-2 and CLC-3,and increased the expressions of Bcl-2 and NF-κB P65.Conclusions Antihypertensive drug NO.1 plays a protective role in hypertension-induced cell injury by changing the metabolic enhancement in hypertension-induced cell volume decrease.

To investigate risk factors and efficacy of reoperation for neovascular glaucoma ( NVG) secondary to vitrectomy in proliferative diabetic retinopathy (PDR).
●METHODS:Seven cases (7 eyes) from October, 2009 to December, 2012 were analyzed retrospectively. All the patients had NVG after the primary vitrectomy for PDR and were performed secondary vitrectomy combined with laser photocoagulation .
●RESULTS: The mean intraocular pressure ( lOP) was (11. 21±4. 22)mmHg before primary surgery. The number of laser spots ranged from 622 to 1124 during the first vitrectomy. Cataract extraction was performed in all 7 cases and intraocular lens was implanted in 5 cases. The mean lOP was (10. 11± 3. 62) mmHg during 2mo after the primary surgery. During follow- up, all the patients had significantly progressive intraocular inflammation. Vitreous hemorrhage was not absorbed completely in 2 cases and recurrent vitreous hemorrhage occurred in the other 5 cases. Five cases had poor glycemic control and the other 2 cases had bad blood pressure control. NVG occurred in all 7cases. The mean lOP was (41. 13 ± 7. 76) mmHg before the secondary surgery. After the secondary surgery, the lOP were under control in 5 cases. For the other 2 cases, the lOP was controlled in one case by transscleral cyclophotocoagulation, another one was lost in follow-up with uncontrolled lOP.
●CONCLUSlON: Primary vitrectomy combined with lens extraction, insufficient laser speckle, unabsorbed and recurrent vitreous hemorrhage, intraocular inflammation and systemic condition may be the risk factors associated with the occurrent of NVG after vitrectomy in PDR. Secondary vitrectomy combined with sufficient retinal photocoagulation is efficiency for NVG after vitrectomy for the PDR.
