Family Schisandraceae is composed of two genera Schisandra and Kadsura, which are quite different in regard to the used part and medical function. Traditionally, the fruits of Schisandra plants were called 'Wuweizi' used as tonic for neurasthenia, antitussive, and sedative agents. The stems and roots of Kadsura plants, with names related to 'XueTeng', possess activating blood circulation and eliminating stasis and are used for the treatment of rheumatism, fractures and irregular menstruation. The dried fruit of Schisandra chinensis was recorded in Chinese Pharmacopoeia (2010 Edition) as 'Wuweizi', while the dried fruit of S. sphenanthera was recorded as an official origin of 'Nanwuweizi'. Historically, there was no evidence that the fruits of Kadsura plants were substituted as 'Wuweizi' either in ancient literatures or contemporary marketing. However, genus Kadsura is still popularly called 'Nanwuweizi' and plant K. longipedunculata is regarded as the origin of 'Nanwuweizi', thus this will cause confusion as well as misunderstanding of genus Kadsura. The authors recommended, therefore, the Chinese name of genus Kadsura should be 'Lengfantengshu' and K. longipedunculata with the name of 'Lengfanteng' in order to guarantee the drug authenticity.

OBJECTIVE:To observe clinical efficacy and safety of Brucea javanica oil combined with gemcitabine and cisplat-in in the treatment of advanced non small cell lung cancer(NSCLC). METHODS:Totally 131 advanced NSCLC patients selected from Huanggang Hospital of TCM during Feb. 2014 to Jan. 2016 were divided into observation group(71 cases)and control group (60 cases)according to random number table. Control group was given Gemcitabine for injection(1st and 8th day)+Cisplatin injec-tion (2nd day),every 21 days,twice as a treatment course. Observation group was additionally given Breucea javanica oil oral emulsion 20 mL,po,2-3 times/d,for consecutive 14 d (3 days before chemotherapy). Both groups received treatment for 87 d and followed up until Jul. 1,2016. Clinical efficacy,the levels of T cell subsets (CD3+,CD4+,CD8+),survival time were ob-served in 2 groups. Single factor and multiple factor analysis was conducted for survival time. The occurrence of ADR was record-ed. RESULTS:The total response rate of observation group (32.39%) was higher than that of control group (25.00%),without statistical significance(P>0.05). Before treatment,there was no statistical significance in the levels of CD3+,CD4+ and CD8+ be-tween 2 groups(P>0.05). After treatment,the levels of CD3+ and CD4+ in observation group were increased significantly,while CD8+ level was decreased significantly;there was statistical significance compared to control group at corresponding period (P<0.05). Four patients withdrew from the study in observation group and 3 patients in control group. The survival time of observation group [(14.02 ± 4.10) months] was longer than control group [(13.21 ± 5.22) months],without statistical significance (P>0.05). Single factor analysis showed that the survival time of patients aged <70 were significantly longer than those of patients aged ≥70;those of patients with pleural effusion were significantly shorter than those of patients without pleural effusion;there was statis-tical significance (P<0.05). Multiple factor analysis showed that with or without pleural effusion,age were influential fac-tors for survival time of patients with advanced NSCLC(OR=1.685 and 0.647,P=0.012 and 0.043). There was no statistical significance in the incidence of ADR between observation group (50.70%) and control group (53.33%)(P>0.05). CONCLU-SIONS:Brucea javanica oil combined with gemcitabine and cisplatin in the treatment of advanced NSCLC patients,although not significantly improve the therapeutic effect,but can significantly improve the cellular immune function. With or without pleural effu-sion and age are infuential facters for survival time of advanced NSCLC patients.

Gene medicine based on recombinant adeno-associated virus (rAAV) vector has rapidly become the prior-choose reagent for gene therapy, since it had been shown that the rAAV was able to stably express many genes in vivo without detectable side-effect. However, recent findings of CTL immune responses to AAV capsid in a clinical trial highlighted a new issue regarding safety that previously was not identified in animal studies. Obviously it is so important to understand the interaction of rAAV with the immune system in details for the safety and success of rAAV gene medicine. In this review we evaluate several current hypotheses aiming to explain the cellular immunotoxicity, also analysis the current findings including the presentation kinetics of the capsid antigen and the activation of CTL. Focusing on the key steps of the immune response several solutions are proposed, including immunosuppression, optimization of vector and improvement of purity, in order to insure clinical safety and efficacy of rAAV.

Objective To characterize the systolic torsion in dilated cardiomyopathy (DCM) by velocity vector imaging(VVI).Methods Eighty-seven subjects were studied using VVI:27 patients with DCM and 60 healthy control subjects.Left ventricular short-axis acoustic images were acquired at base and apex levels.The rotation angle and rotation velocity of endocardium and epicardium were measured.Results LVEF of DCM group was significantly lower than that of control group ( P＜0.01).The basal and apical rotation angle, rotation velocity were significantly lower in DCM group.The endocardial and epicardial rotation angle, rotation velocity were also significantly lower in DCM group than those in control group (P＜0.01).Conclusions VVI is a rapid and noninvasive tool to quantitatively assess cardiac torsional deformation in DCM patients,which providing another useful modality for evaluating cardiac function.

Objective To investigate strain and strain rate of right ventricular(RV)based on twodimensional image by velocity vector imaging in normal subjects.Methods Thirty-two healthy adults were rolled in this study.Echocardiographic images in 4 chamber view were analyzed by conventional manual tracing for volumes and ejection fractions,which were also measured by velocity vector imaging.Myocardial velocity,strain rate,and strain were determined at the basal,mid,and apical segments of the RV free wall and ventricular septum by velocity vector imaging.Results RV ejection fractions obtained with manual tracing correlated strongly with the same indexes obtained by velocity vector imaging method in all subjects(r=0.91,P＜0.01).The strain and strain rate value of middle segment and basal segment in RV free wall were higher than those of apical segment.There were same trend in ventricular septal.The strain and strain rate of middle segment and basal segment in RV free wall were higher than those of homologous segments in ventricular septal,but the indexes of apical segment in free wail and septal had no difference.The strain and strain rate in RV were not correlated with age.Conclusions Velocity vector imaging could accurately and quantitatively assess the strain and strain rate of RV.

Objective To investigate the level of serum angiopoietin-like protein 4 (ANGPTL4) in normal subjects and patients with obesity and newly-diagnosed type 2 diabetes mellitus (T2DM),and to explore the relationship of serum ANGPTL4 with parameters of body fat,glucose-lipid metabolism,and insulin resistance index (HOMA-IR).Methods A total of 160 subjects with normal glucose regulation(NGR) and newly-diagnosed T2DM,were divided into 4 groups:NGR with normal weight group (NGR-NW),NGR with overweight/obese group (NGROW/OB),T2DM with normal weight group (T2DM-NW),and T2DM with overweight/obesity group (T2DM-OW/ OB) according to their body mass index(BMI).ELISA was used to determine the level of serum ANGPTL4.The weight,height,waist circumference,hip circumference,waist hip ratio(WHR),and BMI,fasting insulin(FINS),lipid metabolism parameters,and insulin resistance index (HOMA-IR) were measured.Results Compare with the NGR group,the level of ANGPTL4 was significantly decreased in the T2DM group [(25.75 ±2.85 vs 31.08 ±3.35)ng/ml,P＜0.01],the level of ANGPTL4 in OW/OB group was significantly lower than that in the NW group [(27.27± 3.05 vs 29.04 ± 4.64) ng/ml,P＜0.01].Partial correlation analysis showed that serum ANGPTL4 was negatively correlated with BMI,WHR,FPG,2hPG,HbA1C,FINS,HOMA-IR,AST,ALT,and TG levels(P＜0.01),but positively correlated with the HDL-C(P＜0.01).Multiple stepwise regression analysis showed that HbA1C,FINS,and HDL-C were independent risk factors of serum ANGPTL4 (β =-0.825,-0.119,3.301,P＜0.01).Conclusion Serum ANGPTL4 level in T2DM and OW/OB group was lower than that in NGR and NW group.Serum ANGPTL4 is associated with FINS and lipid metabolism,suggesting that it may play an important role in the pathophysiology of obesity and metabolic syndrome.

OBJECTIVETo study the effect of Qinghuang Powder (QHP) combined Chinese herbs for Pi-strengthening and Shen-reinforcing (CHPSSR) on hypoxia-inducible factor 1alpha (HIF-1alpha) in bone marrow mononuclear cells of myelodysplastic syndrome (MDS) patients.

METHODSChanges of HIF-1alpha in bone marrow mononuclear cells of MDS patients were detected in 25 MDS patients treated by QHP combined CHPSSR using flow cytometry. Meanwhile, 13 healthy subjects were recruited as the control group. Changes HIF-1alpha levels in various serial bone marrow mononuclear cells were detected.

RESULTS(1) Among the 25 patients in the treatment group, there were 19 patients effective and 6 patients ineffective, with the total effective rate being 76%. (2) Compared with before treatment, levels of peripheral blood WBC, Hb, PLT, and ANC significantly increased in the treatment group after treatment, showing statistical difference (P < 0.05, P < 0.01). (3) Compared with before treatment, the HIF-1alpha mean fluorescence intensity was enhanced in bone marrow lymphocytes, monocytes, granulocytes, and nucleated red blood cells of the treatment group after treatment (P < 0.05, P < 0.01). Compared with the control group, the HIF-1alpha mean fluorescence intensity was weakened in bone marrow lymphocytes, monocytes, and nucleated red blood cells of the treatment group before treatment; while it was obviously enhanced in granulocytes (P < 0.01). But after treatment the HIF-1alpha mean fluorescence intensity increased more in the granulocytes of the treatment group than in those of the control group (P < 0.01), but there was no statistical difference in bone marrow lymphocytes, monocytes, or nucleated red blood cells.

CONCLUSIONQHP combined CHPSSR could improve HIF-1alpha levels in bone marrow lymphocytes, monocytes, granulocytes, and nucleated red blood cells of MDS patients, thus improving Hb levels of MDS patients, and improving their anemia and correlated symptoms.
