Good palatability of pediatric drugs improves the accuracy of dosing and adherence to dosing regimens. Many active pharmaceutical ingredients have an undesirable taste, so effective taste masking methods need to be developed to improve the palatability of pediatric medicines. This article mainly introduces the commonly taste masking techniques and taste evaluation methods, and puts forward suggestions on the concerns and general principles of the pharmaceutical evaluation of taste masking effects based on cases, in order to provide reference for the development of drug taste masking technology in children.

Objective:To explore the relationship among professional psychological help-seeking intention,mental symptoms,and self-efficacy in adults.Methods:Totally 618 adult samples[286 males and 332 females,304 early adulthood (18-35 years) and 314 middle adulthood (36-60 years)] were selected on the internet.They were assessed with the Intention of Seeking Counseling Inventory (ISCI),Symptom Checklist 90 (SCL-90) and General Self-Efficacy Scale (GSES) to evaluate professional psychological help-seeking intention,mental symptom and self-efficacy respectively.Results:Females and middle adulthood subjects got higher ISCI scores than males and early adulthood subjects [(82.7 ± 6.7) vs.(77.8 ± 7.8),(83.9 ± 6.2) vs.(76.8 ± 7.3);Ps ＜ 0.001].Step linear regression analysis showed that age,scores of self-efficiency,horror and obsessive-compulsive symptoms had positive prediction effect on help-seeking intention (3 =0.34,0.29,0.10,0.11).Mental symptoms,hostility and paranoia had negative prediction effect on help-seeking intention (β =-0.17,-0.15,-0.11),and the 7 variables could explain 45.6％ of the variation.Conclusion:It suggests that the adults' professional psychological help-seeking intention may be related to subject age,mental symptom and self-efficiency.

Objective To study the effects of traditional Chinese medicine Panax notoginoside(PNS,血塞通) and Tetramethylpyrazine(TMPz,川芎嗪) on different subtypes of cytochrome P450(CYP450),based on that,to forecast the inter-reaction between these two drugs and between each one of them and another drug,and also to estimate the safety assessment of them.Methods The metabolic changes of caffeine and dapsone which are the specific probe drugs for subtypes of CYP450,CYP1A2 and CYP3A4,were studied in vitro to estimate the inhibition or induction effects of PNS and TMPz.Results The concentrations of caffeine and dapsone,the probe drugs in liver cytochrome P450,in control group,PNS group and TMPz group were all declined with time prolongation,and there were no significant differences among the three groups.The half life time(t1/2) of caffeine in PNS group was obviously shorter than that in control group((19.24?2.37) minutes vs.(25.15?2.02) minutes, P0.05).It was suggested that TMPz have no effect on both CYP1A2 and CYP3A4.Conclusion Different drugs have different effects on different CYP450 subtype enzymes.When PNS is used in combination with other drugs which are related to the metabolism of CYP1A2 enzyme,its induction effect on CYP1A2 should be considered fully to avoid toxic effect or the potential adverse reactions.

Objective To investigate the correlation of the anti-cardiolipin(aCL) antibodies and anti-β2 glycoprotein Ⅰ(anti-β2GPI) antibodies in missed abortion women.Methods Fourteen patients diagnosed missed abortion were chose as trial group,while 20 normal females received induced abortion in the same time as control group.Chemiluminescence method was used to measure the serum levels of IgG/IgM aCL and IgG/IgM anti-β2GPI antibodies in the two groups.Results The median levels of serum IgM aCL antibodies and serum IgM anti-β2GPI antibodies in trial group were significantly higher than those of control group(21.3(2.2-39.4)KU/L vs.6.0(1.5-10.7) KU/L,11.9(1.2-25.4) KU/L vs.1.9(1.1-4.0) KU/L;u=2.031,2.912;P ＜0.05).There were no significant differences in terms of the levels of serum IgG aCL antibodies and serum IgG anti-β2GPI antibodies between trial group and control group (P＞0.05).Conclusion There is correlation between IgM aCL as well as IgM anti-β2GPI antibodies and missed abortion,so in reducing the incidence of missed abortion,early and dynamic detection of anti-cardiolipin and anti-β2 glycoprotein I antibodies in childbearing women has a certain clinical significance.

OBJECTIVETo evaluate the protective effects of punicosides on alcohol induced acute liver injury in mice and its possible mechanisms as well.

METHODThe 60 mice were randomly divided into normal control, model group, three dose groups of punicosides with low, medium and high, then there is silibinin group. Three dose groups of punicosides and silibinin were given in advance by gavage for 4 weeks, then the mouse model of alcoholic acute liver injury was established. The serum levels of ALT, AST and TG were determined, and the mice were killed to calculate somatic index of liver, thymus as well as spleen. MDA, SOD, GSH-Px and GSH-ST were detected in the liver homogenate. Histopathological changes of the liver were observed by HE staining. The expression of MCP-1 and NF-kappaB in the liver tissues were detected by immunohistochemistry.

RESULTMid and high dose of punicosides reduced the liver index in mice significantly, improved liver steatosis, decreased the level of ALT, AST and TG in serum and the content of MDA in liver homogenate, furthermore the two dose groups increased the activity of SOD, GSH-Px and GSH-ST, inhibited the expression of MCP-1 and NF-kappaB in liver tissue.

CONCLUSIONPunicosides can protect the acute liver damage induced by alcohol.

OBJECTIVE: To discuss the distribution laws of traditional Chinese medicine (TCM) syndrome factor and their combination in coronary heart disease (CHD), and to study the correlation between the TCM syndrome factor combination and cardiac function as well as blood-lipid. METHODS: The parameters of the cardiac function of 300 patients with a final diagnosis of CHD by coronary angiography were measured by echocardiography, and the levels of blood lipids in the CHD patients were detected. An analysis of the correlation was done between the TCM syndrome factor combination and cardiac function as well as blood-lipid in CHD. RESULTS: The TCM syndrome factor combinations of CHD were blood stasis due to qi deficiency, qi and yin deficiency, intermingled phlegm and blood stasis, and yang deficiency and blood stasis. The ejection fraction of CHD patients with yang deficiency and blood stasis was markedly decreased. The levels of triglyceride and low-density lipoprotein cholesterol in CHD patients with intermingled phlegm and blood stasis were markedly increased, and the level of triglyceride in CHD patients with qi and yin deficiency was markedly increased too. CONCLUSION: The treatment of CHD should aim directly at the symptoms and causes. It is also proved that some compound traditional Chinese herbal medicines for supplementing qi and activating blood circulation, nourishing yin and resolving phlegm, and activating yang should be used in treatment of CHD. In cases of CHD with low cardiac function, particular emphasis should be laid on activating yang and blood circulation, while in cases of CHD with blood-lipid disturbance, particular emphasis should be laid on resolving phlegm and activating blood circulation, replenishing qi and nourishing yin.

Objective To prospectively investigate the characteristics and correlative influential factors of pulmonary hypertension (PHT) in patients on long-term maintenance hemodialysis (MHD). Methods Pulmonary artery systolic pressure (PASP) was assessed by echocardiography according to the guideline from the American Society of Echocardiography in 2010 and PASP more than 35 mm Hg was diagnosed as PHT.Echocardiography and pulse wall velocity (baPWV) was performed in the next day after hemodialysis.Arteriovenous fistula (AVF) flow was evaluated by the ultrasound dilution method.Hemodialysis-related informations and laboratorial parameters were detected in the same period. Results One hundred and eleven MHD patients [male 45,female 66,mean age (57.32±12.49) years old] in our hemodialysis center were included in the study.All of the patients received MHD treatment for more than 6 months with AVF as the vascular access.The patients with any possible diseases causing PHT were excluded.The mean MHD period was (70.51±44.98) months.Twenty-eight patients (25.32％) were diagnosed as PHT with mean PASP (45.68±10.83) mm Hg.Left ventricular diastolic dysfunction was severer in patients with PHT than that in patients without PHT.The prevalence of moderate to severe diastolic dysfunction was statistically higher in PHT group compared to non-PHT group (53.60％ vs 6.02％,P＜0.01).Ejection fraction (EF),fractional shortening of left ventricular diameter in PHT group were also significantly lower than those in non-PHT patients (62.06％±14.90％ vs 69.72％±8.60％,36.46％±10.04％ vs 40.20％±7.86％,P＜0.01).The patients with EF less than 50％ were 21.43％and 3.61％ in PHT and non-PHT group respectively.However,there were no significant differences in age,sex,MHD periods,body mass index (BMI),interval dialysis weight growth,blood pressure before dialysis,hemoglobin,albumin,pre-albumin,serum calcium and phosphorus,iPTH,nPCR,Kt/V,baPWV and AVF flow between the two groups. Conclusions PHT is a common complication of patients on long-term MHD.There is close relationship between PHT and left ventricular insufficiency.PHT is not significantly relevant to mineral metabolic disturbance,AVF flow,hemoglobin,dialysis adequacy and nutrition status.

Objective To study the regulation of microRNA 199a (miR-199a) on adhesion,migration and invasion ability of human eutopic endometrial stromal cells (ESC) from patients with endometriosis.Methods ESC were transfected with miR-199a mimics or negative control (NC) RNA by lipofectamine 2000.The adhesion,migration and invasion ability of ESC were detected by cell adhesion assay,scratch assay,cell migration assay and matrigel invasion assay,respectively.Luciferase reporter assay was used to evaluate whether IKKβ was the target gene of miR-199a.The expression of ikappa B kinase beta (IKKβ),inhibitory kappa B alpha (IκB-α),phospho-IκB-α (p-IκB-α) and nuclear factor-kappa B (NF κB) protein were measured by western blot.Results ( 1 ) Adhesion potential:the adhesion inhibitory rates were ( 14 ± 4 )％ in miR-199a group and 0 in control group,which showed significant difference (P＜0.01 ).(2) Migration and invasion:in the scratch assay,ESC transfected with miR-199a exhibited a lower scratch closure rate than that of controls.In migration and invasion assays,the migration and invasion ability of miR-199a group were significantly decreased compared with those of NC group [ 130 ± 31 vs.247±36 (P＜0.01); 63 ± 15 vs.133 ± 17 (P＜0.01),respectively].(3) The luciferase activity of miR-199a group was significantly lowered than that of control group [ 0.160 ± 0.006 vs.0.383 ± 0.083 ( P ＜0.01 ) ].The protein levels of IKKβ,p-IκB-α,IκB-α and NF-κB of 0.350 ±0.195,0.443 ±0.076,1.970 ±0.486 and 0.454 ± 0.147 in miR-199a group were significantly different compared with the NC group in which the protein levels were set at 1.000 ( P ＜ 0.01 ).Conclusions miR-199a can inhibit the adhesion,migration and invasion of the ESC.IKKβ is the target gene of miR-199a in ESC.One of the mechanisms of the inhibition effect is probably that miR-199a inhibits the activation of NF-κB signaling pathway by targeting IKKβ gene.
