Aim To establish an ideal hyperlipidemia animal model by a new way.Methods 30 mice were randomly divided into control group, positive control group and model group.The mice of control group were only fed with a standard diet.Those of positive control group were fed with high fat diet.Those of model group were fed with a standard diet and enough milk.After 30 days the TG, TC, HDL-C and LDL-C of serum and hepatic and LI were detected and pathological changes in the liver of mice were observed microscopically.Results Compared with the control group, the mice of model group developed hyperlipidemia with LI and the serum and the hepatic TG, TC, LDL-C elevated significantly, while HDL-C were significantly lower.The histopathological research showed hepatocellular macrovesicular steatosis and hepatitis in the model group.Conclusion An ideal model of hyperlipidemia is successfully established with standard diet and milk fed to mice for 30 days.

Objective To compare the specificities of the cell membrane stationary phases(CMSP) with cell membrane chromatography(CMC).Methods Cell chromatographic columns were constructed for both rat aorta tissue cells and cultured rat aorta smooth muscle cells.Then the chromatographic affinities of ten ligands of ?-adrenergic receptor(?-AR) with both said chromatographic columns were investigated.Capacity factors(k'),as a chromatographic parameter,were calculated.Results The correlation analysis showed a positive correlation between the rat aorta tissue CMSP and the cultured rat aorta smooth muscle cell CMSP,with correlation factor of r=0.923,P

A series of 4-(2-acetoxybenzoylamino) butyrate derivatives were designed and synthesized. All of the novel 12 compounds (7a-7k) were synthesized from gamma-aminobutyric acid (1) as starting material, and their structures were confirmed with IR, 1H NMR, EI-MS and elemental analysis. Preliminary pharmacological test in vitro showed that most of these title compounds possessed antiepileptic activity. Compounds 7i-7k displayed strong antiepileptic activity and are worth for further development. Compounds 4, 7d-7h showed moderate antiepileptic activity. The structure-activity relationship of 4-(2-acetoxybenzoylamino) butyrate derivatives is also discussed preliminarily.

AIM: To investigate the clinical therapeutic effects of human umbilical vein (HUV)implantation and mitomycin C (MMC) in non-penetrating trabecular surgery (NPTS). METHODS:A total of 32 patients (46 eyes) with uncontrolled primary open angle glaucoma (POAG) were divided into two groups: HUV+MMC group (n=25), SKGEL+MMC group (n=21). The procedure commenced with the creation of a limbus based conjunctival flap. After the dissection of a superficial limbus based rectangular scleral flap, MMC(0.4mg/mL) was used superior and inferior surface of the superficial scleral flap for three minutes. A second limbus based scleral flap was carefully dissected beneath the previous one towards the choroid. Schlemm's canal was deroofed during the extension of the deep scleral flap toits limbal edges. HUV or SKGEL fixed on the bed of sclera in experimental group. Postoperative examinations were performed at 1 week,2,4 weeks;2,6,12 months. IOP,best-corrected visual acuity(BCVA), functional blebs and success rate were examined. RESULTS: There were no statistically differences with postoperative IOP in HUV+MMC group and SKGEL+MMC group (P>0.05) during 1 week to 12 months. There was no difference with postoperative function blebs and the change of BCVA during 1 week to 12 months between HUV+MMC group and SKGEL+MMC group (P>0.05).At 12 months after surgery, the success rate was 84% in HUV+MMC group,86% in SKGEL+MMC group. CONCLUSION: The application of HUV in NPTS can prevent the adhesion of filtering channel and it can improve the success rate of NPTS. Compared with SKGEL, HUV has lower price. So it is a better implant.

OBJECTIVETo explore the clinical efficacy of self-made Kirschner wire hook in the treatment of severely displaced proximal humerus fractures in children.

METHODSFrom January 2007 to February 2012,35 children with severely displaced proximal humerus fractures were treated with self-made Kirschner wire hook fixation,including 25 boys and 10 girls with an average age of 13.2 years old ranging from 5 to 17. The duration from injury to operation was 1 to 10 days with an average of 4.5 days. Preoperative diagnoses were confirmed by X-ray films as type III in 26 cases and type IV in 9 according to the Neer-Horwitz classification of the proximal humerus fractures. All fractures were close fracture without nerve or vascular injuries. Anatomical reduction was achieved by open reduction and the fractures were fixed by self-made Kirschner wire hook. Intra-operative and postoperative complications, postoperative radiographic examination, upper extremity length and range of shoulder motion were observed and recorded. Neer score system was used to evaluate shoulder function.

RESULTSAll patients were followed up from 6 to 18 months with an average of 12.1 months. The mean Neer score of the injured side was 94.2 +/- 4.8 (ranged, 84 to 99), 30 patients got an excellent result and 5 good according to the Neer scores. The X-ray showed all the fractures healed without shortening deformity or epiphyseal arrest at early stage. There were no complications related to the implant including loosening or breakage of the self-made Kirschner wire hook. The range of shoulder motion in the injuried side was similar to the normal side, except in abductor lift. All the patients could participate in normal physical activities.

CONCLUSIONThe method of open reduction and fixed with self-made Kirschner wire hook is a safe,effective,convenient treatment for severely displaced proximal humeral fractures in children.

Objective To refrain the medical costs from out-of-control increase, and identify a per-disease payment mode suitable for New-CMS.Methods Case studies were conducted on all the data of five diseases in the course of three years, in a field study of the pilot counties for NRCMS in Anhui Province.Results This system of per-disease "pay by segmentation and quota" is composed of five parts: choice of diseases, measurement of payment criteria, method of settlement, method of compensation, and methods of supervision.Conclusion This system is an effective way to keep the medical costs in the NRCMS under control, given an effective play of the five supportive measures including the clinical pathways for individual diseases.

Objective To investigate the clinical characteristics of children with medulloblastoma (MB). Methods The correlations amongst MB histopathological subtype,age at diagnosis,gender,primary tumor locations, relapsed tumor and relapsed tumor locations were analyzed retrospectively in 83 children who were diagnosed as MB by histopathology subtypes from February 2012 to April 2015 in Beijing Shijitan Hospital Affiliated to Capital Medical Uni-versity.The data was conducted by using SPSS 22.0 statistical software.Results Among the 83 cases (53 boys and 30 girls),there were 14 patients younger than 3 years old (9 boys and 5 girls)and 69 patients (44 boys and 25 girls)ol-der than 3 years old,including 28 relapsed (19 boys and 9 girls)and 55 non -relapsed cases (34 boys and 21 girls). The median age was 80.2 (13.1 -184.7)months at diagnosis.Of these 83 cases,48.2% (40 /83 cases)was classic medulloblastoma (CMB)(2 cases less than 3 years old),24.1 % (20 /83 cases)was desmoplastic /nodular medullo-blastoma (DMB)(6 cases less than 3 years old),12.1 % (10 /83 cases)was large cell/anaplastic medulloblastoma (LC /AMB)(1 case less than 3 years old),3.6% (3 /83 cases)was extensive nodular medulloblastoma (MBEN)(1 case less than 3 years old),and 12.1 % (10 /83 cases)(3 cases less than 3 years old)was mixed subtype.The rela-tionships between age at diagnosis and histopathological subtype,gender and primary tumor location were all statistically significant (χ2 =0.014,0.013,all P <0.05).Conclusions The incidence of boys with MB is higher than girls.CMB is the main histopathologic subtype in children over 3 years old.The primary tumor location involving the cerebellar vermis or cerebellar vermis and the fourth ventricle is higher in girls with MB.The primary tumor location involving the fourth ventricle,the fourth ventricle and other parts of the central nervous system,Cerebellar vermis and other parts of the central nervous system or other parts of the central nervous system is higher in boys with MB.

AIM:To compare one-site vs two-site phacotrabe-culectomy in chronic angle-closure glaucoma (CACG) coexisting with cataract.METHODS:This prospective, randomized study included 41 eyes with CACG. One-site approach was performed in 21 eyes and two-site procedure in 20 eyes. Intraocular pressure (IOP), best-corrected visual acuity (BCVA), the number of antiglaucoma medications and complications were observed. All patients were followed up for 9 months.RESULTS:There were no significant differences between the two groups preoperatively. IOP decreased from 22.7±4.9mmHg and 23.7±4.7mmHg preoperatively in one-and two-site groups to 18.0±1.2mmHg and 16.7±1.1mmHg 9 months after operation respectively(P<0.05). There were no significant differences in mean IOP between the two groups at any time (P>0.05). Decrease of the number of antiglaucoma medications and BCVA improvement were similar in both groups 9 months after surgery (P>0.05).There were no significant differences in complications between the two surgical procedures.CONCLUSION:There were no significant differences between the two groups in clinical efficacy and complications.
