Pediatric drug accessibility has become a global problem,pediatric drug shortages and off-label uses are very seri?ous. In China,lack of suitable varieties,appropriate dosage forms and specifications,weak foundations on clinical trials,irregular prescribing behavior and irrational drug use and other issues on pediatric drugs are still outstanding. To improve pediatric drug accessi?bility,it may need all aspects work together,that is,cooperation of the national macro-policy support,participation of enterprises and medical institutions,to establish realistic goals and programs to address pediatric drug problem. This paper studies the foreign pediat?ric regulation measures and policies and by comparing foreign policies to China′s current situation,we can find out the problems and defects,give appropriate advice,in order to provide advice and reference to promote the development of pediatric drug.

Objective To explore the effects of early glucocorticoids (GC) therapy on the outcome of patients with acute respiratory distress syndrome (ARDS). Methods The clinical data of all ARDS patients admitted from January 2008 to December 2011 in Chengdu Military General Hospital of Chinese PLA were retrospectively analyzed. The adult patients whose diagnosis was in accord to the Berlin ARDS diagnostic criteria published in 2012 were enrolled, and based on whether using glucocorticoid or not, they were divided into GC group and non-GC group. All the patients in GC group received low dosage of intravenous GC within 48 hours after the onset of ARDS, including different kinds of GC, methylprednisolone, dexamethasone and hydrocortisone (hydrocortisone dosage < 5 mg·kg-1·d-1, the dosage of former two kinds of GC being converted to that of hydrocortisone), and the therapeutic course of the two groups was 7 to 21 days. The patients in non-GC group received no GC therapy after the occurrence of ARDS. The duration of mechanical ventilation, the length of intensive care unit (ICU) stay and totally in hospital, medical cost and 28-day survival rate were compared between the two groups. Results One hundred and seventeen patients with ARDS were collected, including 56 cases (47.86%) in GC group and 61 cases (52.14%) in non-GC group. The duration of mechanical ventilation in GC group was significantly shorter than that in non-GC group [days:0 (0, 2.50) vs. 2.00 (0, 2.50), Z=2.015, P=0.044]. The 28-day survival rate in GC group was significantly higher than that in non-GC group [71.43%(40/56) vs. 50.82%(31/61),χ2=5.198, P=0.023]. There were no significant differences in the length of ICU stay [days:7.50 (2.00, 11.00) vs. 4.00 (1.00, 9.00), Z=1.879, P=0.060] and stay totally in hospital [days:16.00 (10.00, 27.75) vs. 15.00 (7.00, 28.00), Z=0.592, P=0.552] between GC group and non-GC group. However, the medical cost in non-GC group was significant lower than that in GC group [10 thousand Chinese yuan:3.15 (1.51, 5.78) vs. 4.39 (1.66, 10.88), Z=2.204, P=0.028]. Conclusion The early GC therapy may improve the outcome of patients with ARDS, especially beneficial to the 28-day survival rate.

Objective To investigate the feasibility,safety and efficacy of laparoscopic and endoscopic cooperative surgery (LECS) for elderly patients with gastric gastrointestinal stromal tumor (GIST).Methods 54 cases with GIST aged 65 years and over in Department of Gastrointestinal Surgery in Beijing Hospital from Dec.2008 to Dec.2012 were selected.31 cases underwent LECS and 23 cases underwent open surgery.Clinical data including operation time,intraoperative blood loss,complications,tumor size,length of incision,postoperative gastrointestinal function recovery time,postoperative in hospitalization and follow up data were retrospectively analyzed in patients.Results There were 17 males and 14 females in the LECS group,and the mean age was (72.8±5.9)years.29 patients underwent laparoscopic-assisted partial gastrectomy,and 2 cases underwent laparoscopicassisted endoscopic dissection in LECS group.All operations were successful with no conversion to open surgery and death.There were 13 males and 10 females in the open surgery group,and the mean age was(73.3±6.1)years.The mean operation time was longer in LECS group than in open surgery group [(120.6±32.8) min vs.(86.3±33.5) min].The mean intraoperative blood loss,mean tumor size,mean length of incision,mean time of gastrointestinal function recovery,mean postoperative hospitalization were less or smaller in LECS group than in open surgery group [(40±23.4) ml vs.(130±65.6) ml,(2.3±1.2)cm vs.(3.6 ±1.8)cm,(3.6±1.1) cm vs.(14.4±3.5) cm,(47.7± 10.4)h vs.(61.4±11.9)h,(5.1±2.3)d vs.(7.2±2.5)d,respectively,t=3.192,1.831,5.212,2.014,3.519,P=0.002,0.012,0.000,0.015,0.001].According postoperative tumor risk assessment,13 cases were at very low risk,15 cases at low risk and 3 cases at middle risk in LECS group; 4 cases were at very low risk,14 cases at low risk and 5 cases at middle risk in open surgery group.The risk degree was lower in LECS group than in open surgery group (x2 =5.63,P=0.017).During a follow-up of 5 53 months,death without GIST was found in 5 patients in LECS group and 4 cases in open surgery group.Hepatic metastasis was found in 1 case in open surgery group.Conclusions LECS is a safe and feasibility alternative approach for elderly patients with gastric GISTs.It has more minimal invasion,fast recovery and satisfaction with short term outcomes as compared with conventional open surgery.
