Objective To systemically analyze the efficacy and safety of multi-oil fat emulsion injection (SMOF) in the premature infant parenteral nutrition support.Methods Databases including EMbase,PubMed,Cochrane Library,CNKI,VIP and Wanfang,were searched from libraries establishment to November 2017 for randomized controlled trials (RCTs) focusing on the efficacy and safety of SMOF in the premature infant parenteral nutrition support.All the literatures were retrieved and screened according to inclusion and exclusion criteria by two researchers.The software RevMan 5.3 was used for meta-analysis after the evaluation of methodology of quality.Results A total of 7 articles including 7 RCTs were enrolled.Meta-analysis showed that there were no significant differences in body length (OR=-0.25,95％ CI=-1.80-1.30,P=0.75),weight (OR=-0.12,95％ CI=-0.20-0.04,P=0.14),head circumference (OR=0.07,95％ CI=-0.83-0.96,P=0.88),lowdensity lipoprotein,high-density lipoprotein,direct bilirubin,serum creatinine (OR=-0.16,95％ CI=-0.59-0.26,P=0.45) between the infants receiving SMOF or Intralipid.But compared with the infants receiving Intralipid,hemoglobin (OR=-0.75,95％ CI=-1.49-0.00,P=0.05),red blood cells (OR=-0.23,95％ CI=-0.45-0.00,P=0.05) decreased in the infants receiving SMOF,and white blood cells (OR=1.91,95％ CI=0.46-3.37,P =0.01) increased.Conclusions SMOF can control the hemoglobin content in serum,reduce the risk and degree of jaundice in premature infant,with better safety.

In recent years,the rapid development of fascia plane block technique has played a cru-cial role in the development of multi-modal analgesic strategies in spinal surgery.Compared with traditional intraspinal anesthesia,fascia plane block has the advantages of simple operation,safety,good analgesic effect,no interference to intraoperative nerve monitoring and early postoperative inspection.In this artical,we reviewed the clinical application advances of fascia plane blocks commonly used in spinal surgery,such as transversal abdominis plane block(TAPB),thoracolumbar interfascial plane block(TLIPB),erector spinae plane block(ESPB),mid-point transverse process to pleura block(MTPB),multifidus plane block(MPB),and inter semispinal plane block(ISPB),in order to provide reference for multi-mode analgesia in spinal surgery.

Objective To investigate the effect of transcutaneous electrical acupoint stimulation(TEAS)on emergence agitation(EA)in children undergoing selective posterior rhizotomy(SPR).Methods Forty-two children with cerebral palsy undergoing SPR were selected,20 males and 22 females,aged 6-12 years,BMI 13-24 kg/m2,ASA physical status Ⅰ or Ⅱ,randomly divided into two groups:TEAS group(group T)and control group(group C),21 children in each group.Children in group T re-ceived TEAS at the bilateral acupoints of Neiguan and Hegu from 30 minutes before anesthesia induction to the end of surgery.In group C,electrodes were placed on the same acupoints without electrical stimulation.All children in both groups received total intravenous anesthesia.HR and MAP were recorded at the time of entry,extubation,5,15,30 minutes after extubation.The consumption of remifentanil and propofol during the procedure were recorded.The time of operation and extubation were recorded.The Wong-Baker faces pain scale-revised(FPS-R)and the pediatric anesthesia emergence delirium(PAED)were recorded at 15 minutes after extubation,and the incidence of EA was assessed by PAED.While,the occurrence of post-operative nausea and vomiting(PONV)was recorded.Results Compared with that at the time of entry,HR at the time of extubation,5,15 minutes after extubation and MAP at the time of extubation,5,15,30 minutes after extubation in group C were significantly increased(P＜0.05),HR and MAP at the time of extubation,5,15 minutes after extubationin group T were significantly increased(P＜0.05).Compared with group C,HR was significantly slower and MAP was significantly lower in group T at the time of extuba-tion,5,15,30 minutes after extubation(P＜0.05).Compared with group C,the consumption of remifen-tanil during operation was reduced,the time of extubation was significantly shortened,the FPS-R and PAED were significantly decreased,and the incidence of EA were significantly reduced(P＜0.05).There were no significant differences in the time of operation,the consumption of propofol during operation and the inci-dence of PONV.Conclusion TEAS is beneficial to prevent the occurrence of EA in pediatric patients un-dergoing SPR,stabilize hemodynamics,reduce the dosage of opioids during surgery,reduce the postopera-tive pain,andaccelerate the time of anesthesia resuscitation.

OBJECTIVE To establish the quality standard of Triadica cochinchinensis and to perform the acute toxicity study. METHODS Appearance properties, powder microscopic identification, and thin-layer chromatography(TLC) identification were researched. The specific chromatogram was established by HPLC. The content of cadmium(Cd), lead(Pb), arsenic(As), copper(Cu), and mercury(Hg) was determined by inductively coupled plasma-mass spectrometry(ICP-MS). Acute toxicity was studied by maximum dose. RESULTS The outer skin of herbs was dark brown, and the inner surface was light yellow brown and fibrous. Besides, crystal sheath fiber was common, and calcium oxalate clusters arranges in rows. In the TLC diagram of the test product, the fluorescent spots of the same color were displayed at the corresponding position of the control product(scopoletin, isofraxidin). Five common peaks were calibrated in the characteristic map and the three characteristic peaks(scopoletin, isofraxidin, dimethylfraxetin) were recognized. The content of the measured heavy metal elements was lower than the national limit standard. The linear correlation coefficient was R2 > 0.999. The precision, stability, repetitive RSD were < 10%. The average recovery rate of the added sample was 80%−120%, and the RSD was < 10%. The maximum dose of the acute toxicity test was 184.09 g·kg−1. The 14 d internal body mass, food intake, organ-body ratios, the serum glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, blood urea nitrogen, and creatinine were not significantly different by comparing with the normal controls. Therefore, no significant toxicity was observed. CONCLUSION The established standard can provide a reference for evaluating the quality of Triadica cochinchinensis. The heavy metal content of ten batches of medicinal materials is within the safe range. Acute toxicity test show that there is no obvious significant adverse teactions after oral administration, and the safe dose range is large, which can provide a reference for the subsequent development and utilization.
