A case of traumatic delayed meningo-encephalocele suffered orbital fracture, but bony defects in frontal sinus had not been found on CT scanning. We treated the patient with surgery of intranasal endoscopy and repaired the skull base defect successfully during the first attempt. There was no recurrence in 10 months followed up. The leak site may not correlate with imaging in traumatic delayed meningo-encephalocele by comparing operative findings with the imaging estimate and endoscopy. Therefore, endoscopical approaching is effective in seeking and treatment.

OBJECTIVE:To explore the construction effect of rational drug use monitoring system on the improvement of clini-cal drug use in the hospital. METHODS:The data about the construction of rational drug use monitoring system were collected from our hospital,including pharmacist workstation prescription check(check before prescription/medical order charging to realize warning in advance),clinical pharmacy management system prescription comment(realize prescription/medical order comment after-wards)and adverse drug reaction/adverse drug event(ADR)reporting information platform(realize online ADR reporting)during 2014-2015. The data was analyzed to evaluate the effectiveness of system construction. RESULTS & CONCLUSIONS:There were a total of 3 417 329 prescriptions audited by the pharmacist workstation within 2 years through improving system functions,includ-ing 7 315 prescriptions were returned to doctors to be modified,the percentage of which declined from 0.39% to 0.08%. The pass rate of prescription comment pre-judgment increased from 81.2% to 90.4% in 2015 by clinical pharmacy management system. The valid case number of ADR monitoring and reporting increased from 186 cases to 267 cases,involving all department of our hospi-tal. The construction of rational drug use monitoring system in our hospital can improve the standardization of prescription/medical orders,the level of rational drug use and the case number of ADR,which has achieved the expected results.

OBJECTIVE:To establish a method for the dissolution determination of Benidipine hydrochloride tablets.METHODS:According to Chinese Pharmacopeia(2005 edition),Benidipine hydrochloride tablets were added into hydrochloride acid 0.1 mo?lL-1 at rotation speed of 50 r?min-1,then samples were obtained after 30 min.The absorbance of samples was detected at detection wavelength of 359 nm and accumulative dissolution was calculated.RESULTS:The linear range of benidipine hydrochloride was 5～30?g?mL-1(r=0.999 9)with an average recovery of 99.76%(RSD=0.47%).The accumulative dissolutions of 3 batches of samples were all above 80%.CONCLUSIONS:Established method is simple and reliable for the dissolution determina-tion of Benidipine hydrochloride tablets.

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

Objective To observe the expression of Na+/I- symporter(NIS) in cultured lactating mammary cells with different levels of iodine and the effect of tumor necrosis factor-α(TNF-α). Methods Original generation of mouse lactating mammary cells cultured in vitro were divided into low iodine group Ⅰ (LI-Ⅰ), low iodine group Ⅱ (LI-Ⅱ), adequate iodine group(AI), high iodine group Ⅰ(HI-Ⅰ), and high iodine group Ⅱ(HI-Ⅱ). Cells were cultured in DEME/F12 culture medium for 24 h with different concentrations of iodine (0,5,50,3000 and 10 000 μg/L, respectively), and TNF-α( 10-2 mg/L) was added to some of cultured cells for 24 h. The expression of NIS mRNA of lactating mammary cells was determined by real-time quantitative PCR and the expression of NIS protein was detected by In-Cell Western. Results In iodine alone group, the expression of NIS mRNA in LI-Ⅰ group [ (64.66 ± 14.99) x 10-4] was higher than that of AI group[ (22.76 ± 7.36) × 10-4, P ＜ 0.01 ]; HI-I group[ (10.18 ±3.53) × 10-4] and HI-Ⅱ group[ (8.59 ± 2.89) × 10-4] were lower than that of AI group(all P ＜ .0.05); With increased iodine concentration, the expression of NIS mRNA decreased. The expression of NIS mRNA in LI-Ⅰ group [(2.72 ± 0.45) × 10-4], LI-Ⅱ group[ (2.69 ± 0.68) × 10-4] and AI group[(1.80 ± 0.67) × 10-4] with iodine plus TNF-o were all lower than that of LI-Ⅰ group, LI-Ⅱ group[ (29.82 ± 4.47 ) × 10-4], and AI group without TNF-α (all P ＜ 0.01). In iodine plus TNF-α, the expression of NIS mRNA in HI-Ⅰ group[(6.58 ± 2.87) × 10-4] and HI-Ⅱ[(7.04 ± 1.36) × 10-4] group were all higher than that of AI group(all P ＜ 0.05); With increased iodine deficiency or iodine excess, the expression of NIS mRNA increased. With increased iodine concentration, the expression of NIS protein decreased in iodine alone group. The expression of NIS protein in iodine plus TNF-α was all lower than that in iodine alone group. In iodine plus TNF-α, the expression of NIS protein increased in both iodine deficiency and iodine excess conditions. Conclusions Iodine may decrease the expression of NIS mRNA and protein of lactating mammary cells. The expression of NIS mRNA and protein of lactating mammary cells was inhibited by TNF-α under different levels of iodine.

ObjectiveTo study the morphological and functional changes of thyroid in lactating rats and their offspring in iodine deficiency and iodine excess animal models.MethodsOne hundred and twenty Wistar rats(30 males and 90 females) were selected.Based on their body weight,the 90 females were stratified and randomly divided into five groups( 18 in each group):low iodine group 1 and group 2(fed with low iodine feed and deionized water containing iodine of 0,5 μg/L) ; high iodine group 1,group 2 and control group(feed with normal diet and deionized water containing iodine of 3000,10 000,50 μg/L).After fed for 3 month,all female rats were mated with males in a ratio of 3 ∶ 1.After birth for 10 days,8 female rats and their offspring in each group were sacrificed.Changes of thyroid were observed by naked eyes.The thyroid weight was measured and pathological changes of thyroids were observed under light microscope.Results①Absolute and relative weight of lactating rats thyroid in low iodine group 1 and group 2 [ (92.02 ± 24.40 ),(77.11 ± 23.32 )mg,(0.509 ± 0.072),(0.384 ± 0.089) mg/kg] were much higher than that of control group[ (17.41 ± 9.25)mg,(0.102 ± 0.016)mg/kg,all P＜ 0.05].Absolute and relative weight of lactating rats thyroid in high iodine group 1 and group 2[(8.22 ± 0.41 ),(9.42 ±0.43)mg,(0.047 ± 0.006),(0.035 ± 0.005)mg/kg] were lower than that of control group(all P ＜ 0.05).Absolute and relative weight of lactating rats and their offspring thyroid was decreased with increase of iodide intake in the diet.②Thyroid enlargement of lactating rats in low iodine group 1 and group 2 was evident,but that of high iodine group 1 and group 2 was not.③Epithelial cell hyperplasia and smaller follicular cavity were observed in low iodine group 1 and group 2 under light microscope.Epithelial cell deformation and mostly flat were observed in high iodine group 1 and group 2.ConclusionsThyroid morphology is changed with iodide intake in the lactating rats and their offspring,and the changes are consistent between female rats and their newborns.
