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 construct the eukaryotic expression vector of linker for activation of T cells(LAT) gene in mouse. MethodsLAT cDNA of mouse mononuclear cells was amplified with polymerase chain reaction.The fragment was inserted into the eukaryotic expression vector of pCMV-HA plasmid.The recombinant plasmid was verified by DNA sequencing and used to transfect lymphocytes of the asthmatic model. Results The length of amplified fragment was 729 bp.The sequence of LAT gene was confirmed by Genbank.The LAT protein could be detected in the lymphocytes of asthmatic model.Conclusion The recombinant eukaryotic expression vector pCMV-HA-LAT can be successfully constructed.

Objectives To evaluate the relationship between the expression of B7-1 in liver tissue and the effect of interferon- alpha(α- IFN) treatment in patients with chronic hepatitis B(CHB).Methods The expression of B7 -1in liver biopsy specimens from 68 CHB patients was studied with immunohistochemistry before α-IFN treatment.Results B7-1 was expressed in 45(66.2%) liver tissues among 68 patients with CHB,but none in 5 normal controls.The total response ratio of α- IFN in patients with B7-1 positive was 66.7%(30/45),which was significantly higherthan 39.1%(9/23)in the patients with B7-1 negative(x2 =7.20,P <0.01).B7-1 expression was closely corelat-ed with the histological activity grade(HAI) and serum alanine transaminase(ALT) level.Conclusions The level of B7-1 expression in liver tissue may be regarded as an effective parameter for predicting α-IFN response in patients with CHB.

OBJECTIVE:To compare the clinical efficacy of raloxifene and clomiphene in the treatment of polycystic ovary syndrome(PCOS)complicated with infertility. METHODS:In retrospective study,clinical information of 137 PCOS patients with infertility in our hospital during Jun. 2012-Feb. 2015 were selected and divided into raloxifene group(70 cases)and clomiphene group(67 cases)according to therapy plan. Raloxifene group received Raloxifene tablet 120 mg at the fifth day of menstrual cy-cle,qd,for consecutive 5 d. Clomiphene group received Clomiphene citrate capsule 100 mg at the fifth day of menstrual cycle, qd,for consecutive 5 d. Both groups received B-ultrasound to detect the follicular diameter and endometrial development at the twelfth day of menstrual cycle. When endometrial thickness was ≥7 mm and the diameter of one follicle was ≥18 mm at least,all patients received abdominal subcutaneous injection of Triptorelin acetate injection 0.1 mg to induce ovulation;after 48 h,ovulation was confirmed by B ultrasound. The patients with insufficient luteal function should take dydrogesterone 10 mg as appropriate,q12 h,till 15 d after ovulation. The endometrial thickness,the number of follicles with diameter≥18 mm and follicular maturation time were compared between 2 groups on the day of injection. The sex hormone levels before treatment and on the day of injection,as well as ovulation,outcome indexes and the occurrence of ADR in 2 groups were compared. RESULTS:The endometrial thickness of raloxifene group was greater than that of clomiphene group;the number of follicles with diameter ≥18 mm was more than clo-miphene group;the follicular maturation time was shorter than clomiphene group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in serum levels of P,E2,FSH and LH between 2 groups(P>0.05). Compared to before treatment,there was no statistical significance in serum levels of P,E2,FSH or LH in 2 groups on the day of injection(P>0.05). Serum levels of LH in 2 groups were decreased significantly,and serum level of LH in raloxifene group was significantly lower than in clomiphene group,with statistical significance(P<0.05). The ovulation rate of raloxifene group was significantly higher than clomiphene group,with statistical significance(P<0.05);while the pregnancy rate,abortion rate,continuous pregnan-cy rate of 2 groups had no statistical significance(P>0.05). There was no statistical significance in the total incidence of ADR (5.71% vs. 8.96%)between 2 groups(P>0.05). CONCLUSIONS:Raloxifene has better ovulation induction effect than clomi-phene,and it can improve the sex hormone levels of PCOS patients with infertility,with few ADR,and similarity in long-term clinical effect with clomiphene.

BACKGROUND: It is of significance to imitate facial nerve paralysis of temporal trauma, establish the model of facial nerve paralysis, and study the histopathologic changes of facial muscle after denervation and the effect on rehabilitation of facial muscle function.OBJECTIVE: To investigate the relationship between rehabilitation of facial muscle function and the structural changes of mitochondria and succinate dehydrogenase (SDH) of oris muscles after denervation.DESIGN: A randomized controlled trail based on experimental animals.SETTING: Department of otolaryngology in a hospital of a university.MATERIALS: The experiments were conducted in the Center of Animal Experiment, the Department of Histoembryology, and the Second Electron Microscope(EM) Center, China Medical University. Sixty white guinea pigs provided by the Center of Animal Experiment, China Medical University [certification No: SCXK (liao) 2003-0009 ], were randomly divided into three groups, 5 s squeezed group( n = 15, 10 tested for the function of facial muscle, 5 for EM specimen 15 days after operation), 15 s squeezed group( n =20, 10 tested, 5 for EM specimen 15 days and 30 days after operation), and 30 s squeezed group( n = 25, 10 tested, 5 for EM specimen 15 days after operation and 10 for EM specimen 30 days after operation).INTERVENTIONS: Models of facial paralysis were established. The threshold of facial nerve was detected with electroneurogram(ENoG) before and after squeezed, and the duration of the functional recovery of facial muscle was observed with blink reflex. Orbicularis oris was taken for SDH cytochemical staining, and the ultrastructural changes of SDH positive reaction granules,mitochondria and muscle fibers were observed under transmission electroscope.MAIN OUTCOME MEASURES: ENoG threshold value, tine for recovery of facial muscle function, SDH positive reaction granules and ultrastructural changes of mitochondria and muscle fibers.RESULTS: In 5 s squeezed group, the average inhibition time of nerve excitement conduction was(35.2 ± 16.8) minutes, the structure of mitochondria and the positive reaction granules of SDH remained normal, and the muscle fiber had no pathologic changes. In 15 s squeezed group, it took an average of(47 ± 15) days for blink reflect to recover. In 15 s squeezed group of 15 days, the mitochondria showed slight bubble degeneration and the SDH granules decreased and the muscle fiber had slight pathologic changes, but recovered after 30 days. The mitochondria changed severely and SDH granules decreased significantly in 30 s squeezed group of 15 days and 30 days; no case of blink reflect recovered within' half a year.CONCLUSION: The longer the facial nerve is injured, the nore severely the function of facial muscles is damaged, and the more difficultly it will recover. Therefore, facial nerve decompression should be performed as early as possible.
