Objective To explore the efficacy and safety of TACE and apatinib combined with camrelizumab for treating giant hepatocellular carcinoma(HCC).Methods Totally 78 patients with giant HCC were retrospectively collected,including 22 cases received TACE and apatinib combined with camrelizumab(TACE+AC group)and 56 cases received TACE and apatinib(TACE+A group).Propensity score matching analysis was used to select 44 cases(TACE+A'group)from TACE+A group who were matched to those in TACE+AC group at 1:2 ratio.The overall survival(OS),progression-free survival(PFS)and the adverse events were recorded and compared among groups.Results Patients in TACE+AC group had a median OS of 17.8(95％CI:17.5-18.1)months and a median PFS of 8.8(95％CI:5.4-12.3)months,which in TACE+A'group was 9.8(95％CI:7.6-12.1)months and 5.5(95％CI:2.7-8.3)months,respectively.The overall OS rate and PFS rate in TACE+AC group were significantly higher than those in TACE+A' group(both P<0.05).The incidences of thyroid dysfunction,immune pneumonia and reactive cutaneous capillary endothelial proliferation in TACE+AC group were significantly higher than those in TACE+A' group(all P<0.05).No death associated with adverse events occurred.Conclusion Compared with TACE and apatinib,further combining with camrelizumab could get better survival benefit for giant HCC patients with acceptable adverse events.

Objective:To explore the effectiveness of a multimodal TeamSTEPPS course based on clinical cases in training surgical teams led by anesthesiologists, improve team cooperation in crisis management, and enhance clinical safety.Methods:The Department of Anesthesiology at Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, combined the TeamSTEPPS course with problem-based learning. Based on eight clinical cases, simulation-based training was conducted for interdisciplinary personnel, including anesthesiologists, surgeons, and operating room nurses. Pre- and post-training evaluations were conducted for 80 participants on theoretical knowledge and teamwork. Statistical analysis was performed using SPSS 27.0 software. The differences in scale scores before and after training were tested for normality. If normally distributed, results were expressed as mean ± standard deviation and analyzed using paired t-tests. Participant demographic data were represented using percentages. Results:The theoretical assessment scores after training were significantly higher than those before training [(76.45±8.34) vs. (60.21±5.90), t=13.55, P<0.001]. TeamSTEPPS Teamwork Perception Questionnaire and TeamSTEPPS Teamwork Attitudes Questionnaire scores were significantly higher after training than before training [(156.08±15.20) vs. (149.32±15.58) and (134.59±10.71) vs. (128.47±10.89)], with statistically significant differences ( P<0.001). Conclusions:The TeamSTEPPS management course in combination with problem-based learning can enhance the clinical theoretical knowledge of anesthesiologists and improve their team awareness and collaboration, thus improving their clinical competence in managing crisis events.

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 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.

Nei Jing says:Tian Qi connects Lung. Cough is closely associated with the seasons’change of climate which means four seasons and six pathogenic factors,so we must combine the clinical treatment of cough with the seasons’change of climate,which conduct an overall analysis of the illness and the patient's condition. It is favorable to drive out pathogenic Qi and restore healthy one.
