Cerebral palsy greatly affects walking function of the child patients, showing low-effective walking gait. Orthosis is used to change function features or structures of nerve, muscle and skeletal system. Ankle-foot orthosis is commonly used, which could provide appropriate movement control on sagittal, coronal and horizontal planes, maintain joint line of force arrangement, promote functions and improve gait. However, ankle-foot orthosis exhibits some limitations, such as limited range of joint motion, limited muscle function, and infection due to local skin compression. Therefore, clinical doctors and researches are looking for improvements over the past years, for example, to supplement some treatment or protective function based on current orthosis, so as to obtain better clinical outcomes. Appropriate and individualized orthosis is development direction of orthosis creation and design.

OBJECTIVE:To provide reference for regulating pediatric clinical drugs. METHODS:Package inserts of pediatric drugs used by the outpatient,inpatient and emergency pharmacies of our hospital during January and March in 2015 were collected. The information about pediatric drugs in the package inserts,including drug name,indications or functions,specification,adminis-tration and dosage,was calculated and analyzed. 815 kinds of drugs applicable to adults and children in our hospital were studied to summarize and analyze the dosage form,specification and dose of pediatric applicable drugs. RESULTS:438 package inserts were collected,including 327 related to chemicals and biologicals among which those imported or produced by sino-foreign joint venture were labeled with more complete information about drug use for children compared to those made in China,and 111 rele-vant to Chinese patent medicines and natural medicines for which there were significantly insufficient information about drug use for children. The applicable drugs with the dosage form for children and those with the specification therefor respectively accounted for 51.17% and 31.65% of the above-mentioned 815 kinds of drugs,and were mainly available as injections,tablets or capsules, granules and oral liquid. The drugs labeled with the dose based on the age group of children such as infant,preschooler,school child and adolescent(1-18 years old)accounted for 61.24% of those with the specification for children,the drugs labeled with the dose for babies (28 d-1 year old) accounted for 26.74% thereof,and the drugs labeled with the dose for neonatus (younger than 28 d)accounted for 12.02% thereof. CONCLUSIONS:The label information and variety of pediatric applicable drugs are marked-ly insufficient. It is suggested that our country should formulate relevant policies,strengthen the development of pediatric drugs and improve the data for clinical use thereof to ensure the safety of clinical use for children.

ObjectlveTo evaluate the role of cannabinoid receptor 2 (CB2 receptor) in microglial injury induced by glutamate.MethodsMicroglia cells were randomly divided into 4 grups:control group (group C),microglial injury group ( group Ⅰ),specific CB2 receptor agonist AM 1241 group ( group AM1241 ) and specific CB2 receptor antagonist AM630 group (group AM630).In group C,the cells were cultured routinely for 26 h.In group Ⅰ,the cells were incubated in the culture medium containing glutamate 10 mmol/L for 24 h.In group AM1241,the cells were incubated in the culture medium containing AM1241 2 μmol/L for 2 h,and then in the culture medium containing glutamate 10 mmol/L for 24 h.In group AM630,the cells were incubated in the culture medium containing AM630 2 μmol/L for 2 h,and then in the culture medium containing glutamate 10 mmol/L for 24 h.The cell viability and release of LDH were measured.Microglial morphology was observed under microscope.Results Compared with group C,the cell viability was significantly decreased,and the release of LDH was significantly increased in groups Ⅰ,AM1241 and AM630 (P ＜ 0.05).Compared with group Ⅰ,the cell viability was significantly increased,and the release of LDH was significantly decreased in group AM1241 ( P ＜ 0.05).There was no significant difference in the cell viability and the release of LDH between groups 1 and AM630 ( P ＞ 0.05).Conclusion Glutamate induces microglial injury through inhibiting the function of CB2 receptor.

Objective To investigate the antagonistic effect of wogonin in combination with 5-fluorouracil (5-FU) on the proliferation of human Hep-G2 hepatocellular carcinoma cells .Methods Human hepatocellular Hep-G2 cells were divided into experimental group (wogonin group ,5-FU group ,wogonin + 5-FU group) and control group .MTT method was used to eval-uate tumor cell proliferation in vitro ,flow cytometry analysis was used to evaluate tumor cell apoptosis .Results The results showed that the wogonin inhibited the proliferation of tumor cells at the concentrations of 5 ,10 ,20 and 40 μmol/L after 24 h and 48 h treatment respectively (P<0.05);5-FU also inhibited the proliferation of tumor cells at the concentrations of 5 ,10 , 20 and 40 mg/L after 24 h and 48 h treatment respectively (P< 0.05) .However when wogonin was combined with 5-FU (wogonin+5-FU group) ,an antagonistic effect was observed on tumor cell proliferation (P<0.05) .When cells were treated by wogonin+5-FU for 48 h ,the combined index (CI) value slowed a dose-dependent antagonistic effect (P<0.05) .Conclusion Wogonin has anti-tumor effect .However when wogonin was combined with 5-FU ,an obvious antagonistic effect on 5-FU′s anti-tumor action was observed .The underlying mechanism deserves further study .

OBJECTIVE: To identify phytochemical constituents present in the extract of flowers of Xanthoceras sorbifolia and evaluate their anti-oxidant and anti-hyperglycemic capacities. METHODS: The AlCl₃ colorimetric method and Prussian Blue assay were used to determine the contents of total flavonoids and total phenolic acids in extraction layers, and the bioactive layers was screened through anti - oxidative activity in vitro. The Waters ACQUITY UPLC system and a Waters ACQUITY UPLC BEH C₁₈ column (2.0 mm × 150 mm, 5 μm) were used to identify the ingredients. And anti-oxidative ingredients were screened by off-line UPLC-QTOF-MS/MS-free radical scavenging. The ameliorative role of it was further evaluated in a high-fat, streptozotocin-induced type 2 diabetic rat model and the study was carried out on NADPH oxidase (PDB ID: 2CDU) by molecular docking. RESULTS: Combined with the results of activity screening in vitro, the anti - oxidative part was identified as the ethyl acetate layer. A total of 24 chemical constituents were identified by liquid chromatography-mass spectrometry in the ethyl acetate layer and 13 main anti-oxidative active constituents were preliminarily screened out through off-line UPLC-QTOF-MS/MS-free radical scavenging. In vivo experiments showed that flowers of X. sorbifolia could significantly reduce the blood glucose level of diabetic mice and alleviate liver cell damage. Based on the results of docking analysis related to the identified phytocompounds and oxidase which involved in type 2 diabetes, quercetin 3-O-rutinoside, kaempferol-3-O-rhamnoside, isorhamnetin-3-O-glucoside, and isoquercitrin showed a better inhibitory profile. CONCLUSION The ethyl acetate layer was rich in flavonoids and phenolic acids and had significant anti-oxidant activity, which could prevent hyperglycemia. This observed activity profile suggested X. sorbifolia flowers as a promising new source of tea to develop alternative natural anti-diabetic products with a high safety margin.
