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.

OBJECTIVE: This paper aimed to evaluate the effectiveness of the 3D printing puncture navigation template-guided percutaneous radiofrequency thermocoagulation for V2 trigeminal neuralgia treatment. METHODS: A total of 52 patients with V2 trigeminal neuralgia were treated with radiofrequency thermocoagulation. A total of 32 patients were treated under the guidance of the 3D printing puncture navigation template (guide plate group), while 20 patients underwent puncture via pterygopalatine fossa routinely (routine treatment group). The puncture time, operation time, puncture success rate, and immediate postoperative pain were recorded. The degree of immediate postoperative pain was indicated by visual analogue scale (VAS). Barrow Neurological Institute (BNI) classification criteria were used to evaluate the efficacy, and the postoperative complications were observed. All patients were followed up for 1 year. RESULTS: The two groups showed significant decrease in VAS after the operation (P<0.05). The puncture and operation times of the guide plate group were significantly lower than those of the routine treatment group (P<0.05). The difference in terms of the clinical effects and recurrence rate between the two groups was insignificant (P>0.05). CONCLUSIONS 3D printing puncture navigation template-guided radiofrequency thermocoagulation may increase the operation success rate and reduce complication incidence. Therefore, this technique possesses clinical promotional value.

OBJECTIVE: To study the correlation of dynamic change in serum 25-hydroxy vitamin D [25(OH)D] level with the disease severity and related laboratory markers in infants/toddlers with severe pneumonia. METHODS: A total of 132 infants/toddlers with severe pneumonia who were hospitalized between March 2017 and March 2018 were enrolled as the severe pneumonia group. According to the disease severity on admission and after one week of treatment, they were further divided into non-critical group (41 children on admission and 78 after one week of treatment), critical group (59 children on admission and 35 after one week of treatment), and extremely critical group (32 children on admission and 19 after one week of treatment). A total of 142 infants/toddlers who underwent physical examination during the same period of time were enrolled as the healthy control group. The serum levels of 25(OH)D, procalcitonin (PCT), and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured on admission and after one week of treatment for the severe pneumonia group, and the serum level of 25(OH)D was measured on admission for the healthy control group. According to the 25(OH)D level after one week of treatment, the children with severe pneumonia were divided into increased vitamin D (VD) group with 81 children and reduced VD group with 51 children, and a comparative analysis and a correlation analysis were performed. RESULTS: The severe pneumonia group had a significantly lower mean 25(OH)D level than the healthy control group (P<0.05), and all the three subgroups of different severities had significantly lower 25(OH)D level than the healthy control group (P<0.05). On admission and after one week of treatment, the non-critical group had a significantly higher 25(OH)D level than the critical and extremely critical groups (P<0.01), and the critical group had a significantly higher 25(OH)D level than the extremely critical group (P<0.05). The extremely critical and critical groups had significantly higher serum levels of PCT and NT-proBNP than the non-critical group on admission and after one week of treatment (P<0.05). After one week of treatment, compared with the reduced VD group, the increased VD group had a significantly less serious condition. At discharge, the increased VD group had a significantly better outcome compared with the reduced VD group (P<0.01). In the children with severe pneumonia, the change value of serum 25(OH)D level after treatment was negatively correlated with the change values of PCT and NT-proBNP (r=-0.597 and -0.404 respectively; P<0.01). CONCLUSIONS The change in VD level is correlated with the severity of severe pneumonia in infants/toddlers and can be used as an index for disease monitoring. VD supplementation may help with disease recovery.

Objective To study miRNA expression differences in ovalbumin(OVA)- induced murine asthma models of mice and mast cells stimulated by inflammatory cytokines stimulation,and to better understand asthma deve-lopment so as to provide potential target for its prevention and treatment. Methods OVA - induced murine asthma models were validated by detecting cells in bronchoalveolar lavage fluid(BALF)and histopathology. And miRNA ex-pression differences in the lung tissues between the model group and the normal control group were detected by real -time polymerose chain reaction PCR . After tumor necrosis factor - α(TNF - α),interleukin 12(IL - 12)stimulation, miRNA expression differences in murine mast cells P815 were detected. Results The number of total cells and eosino-phil cells both increased in BALF of the model group[(12. 8 ± 2. 2)x 107 / L vs(5. 6 ± 2. 5)x 107 / L,t = 4. 760,P ﹤0. 05;(6. 6 ± 1. 9)x 107 / L vs(0. 8 ± 0. 8)x 107 / L,t = 8. 068,P ﹤ 0. 05]. In addition,histopathology showed more inflammatory cell infiltration in the model group than that in the normal control group,indicating that the models were validated. The expression of miRNA - 155 was up - regulated approximately 5. 0 - fold in the lung tissues of the model group(P ﹤ 0. 05),while miRNA - 192 showed no differences compared with the controls. After TNF - α and IL - 12 stimulated P815 mast cells,miRNA - 192 expressions in P815 were expression in P815 was up - regulated approximate-ly 1. 9 - fold and 1. 7 - fold after TNF - α and IL - 12 stimulation,respectively(P ﹤ 0. 05). Conclusions It is conclu-ded that miRNAs are differentially expressed in the presence of OVA - induced murint asthma models and mast cells stimulated by inflammatory cytokines. These differentially expressed miRNAs may regulate the function of mast cells and involved in the pathogenesis of asthma.

OBJECTIVETo investigate the effect of two methods of pigmentation on the flexural strength of dental Y-TZP/porcelain layered structure.

METHODSKaVo zirconia substructures were pigmented by dipping presintered blocks in the coloring solution VITA LL1 and LL5, and colored TZ-3YS zirconia substructures were fabricated by adding pigments before isostatic pressing. The colors No.1 and No.5 were used for the test. The specimens were made in monolithic or bilayered forms, and the flexural strength was tested. XRD and SEM with EDX were used to analyze the characteristics of the surface structure.

RESULTSIn KaVo group, no significant differences were found in the flexural strength between white and LL1 and LL5 colored monoclinic materials, nor in bilayered structures. While in TZ-3YS group, significant differences were noted in the flexural strength between color No.5 white and color No.1 monoclinic materials, but not between the latter two subgroups. The flexural strength was significantly lowered by veneering with porcelain in both zirconia groups, and similar findings were observed with the monoclinic materials. Only the tetragonal phase was detected in both of the zirconia groups.

CONCLUSIONPigmentation has no apparent effects on the bonding strength between the veneering porcelain and zirconia. Both coloring methods are appropriate when the concentration of the pigments is under deliberate control.
