Objective To determine whether the supplementation of ω-3 polyunsaturated fatty acids in parenteral nutrition (PN) confers treatment benefits to outcomes of septic patients.Methods The databases of MEDLINE,EMBASE,Cochrane central register of controlled trials,the CNKI and the Wanfang biomedicine were searched to identify prospective randomized controlled trials (RCTs) which compared the ω-3 polyunsaturated fatty acids supplemented with the standard PN on outcomes of adult patients with sepsis from January 1996 to June 2013.The methodological quality of the included studies was evaluated,and the Cochrane Collaboration RevMan 5.0 was used for data analysis.Results A total of 12 studies enrolling 721 patients were included.Significant reduction in 28-day mortality [relative risk (RR) 0.77,95％ confidence interval (95％CI) 0.59 to 0.99,P=0.04],short intensive care unit [ICU,weighted mean difference (WMD)=-3.10,95％CI-5.98 to-0.21,P=0.04] and hospital length of stay (WMD =-3.12,95％CI-4.65 to-1.60,P＜0.000 1) were observed in patients receiving ω-3 polyunsaturated fatty acids supplemented PN.There was no differences in days of mechanical ventilation between patients with or without adding ω-3 polyunsaturated fatty acids in PN (WMD =1.33,95％ CI-5.09 to 7.75,P=0.69).Conclusions Meta-analysis results demonstrated that PN supplemented with ω-3 polyunsaturated fatty acids was beneficial in improving the outcomes of patients with sepsis.However,this conclusion must be interpreted with caution due to the low quality of the enrolled trials.

Objective To explore the etiology, pathogenesis, syndrome differentiation and treatment for dengue fever according to the theory of traditional Chinese medicine ( TCM) . Methods A retrospective case analysis was carried out in 257 dengue fever patients admitted in 2013 by Guangdong Provincial Hospital of Traditional Chinese Medicine. The clinical data of pathogenic features, TCM symptoms and signs, and therapeutic regimen were collected and analyzed. Results Six commonly-seen TCM syndrome patterns for dengue fever were classified into disease involving both defensive system and Qi system, excessive heat in defensive system, summer-heat and dampness stagnating the middle-jiao or attacking the exterior, excessive heat in both Qi system and blood system, pathogenic factors lodging between diaphragm and pleura, and mixture of blood stasis and toxicity, and the corresponding prescriptions were Yinqiao Powder, Chaige Jieji Decoction, Xinjia Xiangru Decoction, Qingwen Baidu Decoction, Dayuan Decoction, Xijiao Dihuang Decoction, respectively. Conclusion The TCM syndrome patterns of dengue fever in Guangzhou area are characterized as excessive heat in Qi system, complicated with nutrient and blood system syndrome, and mostly are blended with dampness. Correspondingly, the therapeutic principles should be clearing heat and removing toxicity in Qi system with cold-cool herbs, and assisting with cooling blood to clear heat in Qi system and removing dampness.

Objective Using an adenoviral vector , the wild-type PTEN gene was transduced into activated hepatic stellate cell (HSC) in vitro and the phosphorylation status of Akt were investigated. Methods The wild type PTEN gene was transduced into activated HSC in vitro mediated by adenoviral vector. The expressions of PTEN and total Akt in HSC were measured by Western blot and Real-time fluorescent quantitation PCR. And the expressions of phosphorylated Akt (Thr308) in HSC was determined by Western blot. Results The data showed that exogenous wild type PTEN gene was successfully transduced and expressed in activated HSC in vitro. The over-expression of wild type PTEN resulted in the significant down-regulated expression of phosphorylated Akt (Thr308) in activated HSC (P < 0.01). But no significant defferences were found in the expression of total Akt in activated HSC at both transcriptional and translational levels(P>0.50). Conclusions The overexpression of wild-type PTEN can negatively regulate PI3K/Akt signaling transduction by inhibiting the phosphorylation of Akt in activated HSC in vitro.

OBJECTIVE:To investigate the effects of UGT1A4142T>G polymorphism and blood concentration of valproic ac-id(VPA)on blood concentration of lamotrigine(LTG)in southern Chinese Han children with epilepsy,and to establish the predic-tion equation for quantitatively estimating blood concentration of LTG. METHODS:A total of 72 southern Chinese Han children with epilepsy selected from Guangzhou Women and Children's Medical Center during Jan. 2010-Sept. 2016 were given LTG+VPA. LC-MS/MS and enzyme amplified immunoassay were adopted to determine the blood concentration of LTG and VPA. RFLP-PCR was adopted to determine UGT1A4142T>G polymorphism. The relationships of age, gender, blood concentration of VPA, UGT1A4142T>G polymorphism and LTG concentration-to-dose-ratio (CDR) were also investigate. The prediction equation for blood concentration of LTG was established by multiple linear regression analysis. RESULTS:Age and blood concentration of VPA were positively related to CDR of LTG(r=0.225,0.300,P<0.05);there was no statistical significance in the influence of gender on CDR of LTG(P>0.05). UGT1A4 TT,TG and GG genotypes were detected in 39,29,and 4 cases respectively;the frequencies of each genotype were in line with the Har-dy-Weinberg balance(P>0.05). CDR of LTG of TT genotype was significantly lower than those of TG and GG genotype,with sta-tistical significance(P<0.05). Results of multiple linear regression analysis showed that the dose of LTG(x1),body weight(x2), blood concentration of VPA(x3)and UGT1A4142T>G polymorphism(x4)were all related to blood concentration of LTG(P<0.05). Using blood concentration of LTG(c)as dependent variable,above factors as independent variable,the regression equation was c=0.794+0.032x1-0.057x2+0.010x3+0.532x4(R2=0.616,P<0.05;UGT1A4 TT genotype was equal to 0,TG and GG genotype was equal to 1). There was a strong positive correlation between predicted blood concentration and measured ones(r=0.785,P=0.001). CONCLUSIONS:The dose of LTG,body weight,blood concentration of VPA and UGT1A4142T>G polymorphism may associated with blood concentration of LTG. Established prediction equation can provide reference for precise medication in south-ern Chinese Han children with epilepsy.

Objective To investigate the effect of age,gender,weight and UGT1A4142T>G gene poly-morphism on the efficacy of LTG in epileptic children treated with valproic acid ,and to determine the effective se-rum concentration of LTG in children with epilepsy in south China. Methods A total of 72 pediatric patients with epilepsy received LTG and VPA treatments were enrolled in this study. Patients were treated from January 2010 to September 2016 in Guangzhou women and childrens′medical center. Serum concentration of LTG was measured by using the liquid chromatography-tandem mass spectrometry. UGT1A4142T > G was genotyped by the polymerase chain reaction-restriction fragment length polymorphism method. The correlations between the efficacy of LTG and age,gender,weight were analyzed by chi-square test,non-parametric test and logistic regression analysis,respec-tively. Results The curative effect of patients who were younger and with lighter weight were relatively poor ,and men were better than women in the curative effect. UGT1A4142T > G was not related with LTG efficacy. When combined with VPA,the effective serum concentration of LTG in children with epilepsy was more than 2 g/mL. Conclusion There is a good correlation between age and LTG curative effect. The effective serum concentration of LTG in children with epilepsy,who were co-treated with VPA,was more than 2 g/mL. This study provides a refer-ence for the individual administration of children with epilepsy in south China.

Objective To explore the relationship between non-high density lipoprotein cholesterol(non-HDL-C)level and leptomeningeal collateral circulation in patients with acute middle cerebral artery occlusion.Methods A total of 85 patients with first-onset acute cerebral infarction with middle cerebral artery M1 segment occlusion were enrolled.According to the results of DSA,LMC circulation was assessed by American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology Collateral Circulation Assess-ment System.All patients were assigned to better LMC circulation group(score 2～4,n = 30)and worse LMC circulation group(score 0～1,n = 55),and the levels of non-HDL-C were compared between the two groups.Results The levels of LDL-C and non-HDL-C in worse LMC circulation group were significantly higher than those of the better LMC circulation group(P = 0.026,P = 0.010).non-HDL-C was an independent risk factor for the worse LMC circulation(OR = 3.019,95%CI:1.053～8.658,P = 0.04).LMC circulatory score of patients was negatively correlated with the levels of non-HDL-C level(r =-0.228,P = 0.036).The AUC of non-HDL-C predicted for the worse LMC circulation was 0.638(95%CI:0.521～0.755,P = 0.036).Conclusions non-HDL-C in patients with acute cerebral infarction was significantly related to worse LMC circulation,and was a risk factor for worse LMC circulation.It is suggested that the higher expression of non-HDL-C could be used to predict worse LMC circulation as a serological indicator.

Anti-seizure medications (ASMs) are the main therapy for epilepsy.There are many kinds of ASMs with complex mechanism of action, so it is difficult for pharmacists to examine prescriptions.This paper put forward some suggestions on the indications, dosage forms/routes of administration, appropriateness of usage and dosage, combined medication and drug interaction, long-term prescription review, individual differences in pathophysiology of children, and drug selection when complicated with common epilepsy, for the reference of doctors and pharmacists.
