1.Discussion on the concerns in paediatric drug taste masking technology and evaluation
Acta Pharmaceutica Sinica 2023;57(11):3173-3178
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 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.

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.

[ABSTRACT]OBJECTIVEThe purpose of this study was to analyze the screened miRNAs related to the chemosensitivity for the TPF regimen of hypopharyngeal squamous cell carcinoma by miRNA array, and provide a set of miRNAs that may be useful for the development of novel diagnostic markers and more effective therapeutic strategies from the screened miRNAs.METHODSA total number of 21 patients who underwent TPF induction chemotherapy for primary hypopharyngeal squamous cell carcinoma were recruited for miRNA array analysis. 12 patients are sensitive to chemotherapy, and 9 patients are not. Moreover, the selected putative regulated miRNAs were also validated by RT-PCR in another 24 patients (14 patients are sensitive to chemotherapy, and others are not).RESULTSThere were 24 miRNA significantly differencial to the sensitivity to chemotherapy, and 6 miRNAs were up-regulated in the TPF group while 18 miRNA were down-regulated (P<0.05). To identify typical miRNA, mirfocus 3.0 database selected four miRNAs hsa-miR-211-3p, hsa-miR-4253, hsa-miR-4443, and hsa-miR-193b-3p, which were significant down-regulated in TPF-sensitive group. QRT-PCR further validated that only three miRNA (hsa-miR-4253、hsa-miR-4443、hsa-miR-193b-3p) were under-expressed in TPF-sensitive group of another 24 tissue samples (P<0.05).CONCLUSIONMiRNA hsa-miR-193b-3p, hsa-miR-4253, hsa-miR-4443 were identified in TPF-sensitive tissues by microarrays, and further validated by RT-PCR. These down-regulated miRNAs may act as novel biomarkers to classify TPF sensitivity of hypopharyngeal squamous cell carcinoma patients and will contribute to the understanding of the molecular basis of the chemosensitivity in the disease.

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.
