Objective To investigate the therapeutic effect of buflomedil hydiochoride for on jection inpro- gressive ischemic stroke.Methods 60 patients with cerebral infarction were divided into buflomedil hydrochoride for injection treatment group and control treatment.Then the nepal function deficits of patients were evaluated before and after 15 days.Serum MMP-9 levels in vein blood samples of ischemie stroke were detected.Results The inci- dence rate of progressive ischemic stroke in treatment group of buflomedil hydrochoride for injection was lower than that of control treatment group(P

· AlM:To investigate the effect of compound anisodine on fundus blood circulation after vitrectomy with face-down position.
· METHODS: Sixty patients ( 60 eyes ) with rhegmatogenous retinal detachment received vitrectomy with silicone oil tamponade operation, who were randomized divided into treatment group ( 30 eyes ) and control group ( 30 eyes ) .The patients in the treatment group received the subcutaneously injection of compound anisodine hydrobromide by the superficial temporal artery once daily for 14d since postoperative first day.Retinal microcirculation blood flow parameters were recorded with Heidelberg retinal flowmeter postoperative 1d, 1 and 2wk, and were compared between two groups.
·RESULTS: The blood flow parameters ( Vol, Flw, Vel) of control group postoperative 1 and 2wk were significantly less than those postoperative 1d.Otherwise the parameters of treatment postoperative 1 and 2wk were significantly more than those postoperative 1d. The parameters between two groups were significant different ( P<0.01) .
· CONCLUSlON: Facing down after vitrectomy with
silicone oil tamponade may reduce retinal blood supply, consequently lead to retinal ischemia; compound anisodine can effectively improve the retinal and choroidal microcirculation after vitrectomy with face-down posture, reduce retinal ischemia, and enhance the visual function.

?AIM: To observe the clinical curative effect of the intravitreal injection of anti-VEGF antibody combined with the implantation of Ex-press glaucoma drainage device for neovascular glaucoma ( NG) .?METHODS:A retrospective analysis of 20 patients with NG, who got the intravitreal injection of anti -VEGF antibody combined with the implantation of Ex-press. The visual acuity, intraocular pressure ( IOP ) , iris neovascularization fade and intraoperative and postoperative complications were observed at 1wk, 1, 3 and 6mo postoperatively.?RESULTS:The average IOPs of 20 patients were 47 ± 5.6mmHg, 13.4 ±3.6mmHg, 15.3 ±4.2mmHg, 16.9 ± 5.3mmHg and 18.7 ±6.9mmHg preoperatively and postoperatively 1wk, 1mo, 3mo and 6mo with statistical difference (P<0.05).The intraoperative and postoperative complications of the implantation of Ex-press mainly included early shallow anterior chamber, drainage tube obstruction, filtering bleb scarring. There were 8 eyes with filtering bleb scarring with normal IOP.?CONCLUSION: The intravitreal injection of anti-VEGF antibody combined with implantation of Ex -press is effective for NG, which can significantly reduce the IOP.

Objective To investigate the value of combined detection of multi-tumor markers in the diagnosis of primary hepatocellular carcinoma (HCC) and to establish the discriminant equation. Methods Using a protein chip, 12 tumor markers in the serum from 98 patients with HCC and 67 patients with benign liver diseasewho had been admitted to Daping Hospital from November 2003 to April 2006, and 46 healthy individuals during he same period were analyzed. A discriminant equation was established to discriminate primary HCC from benign liver diseases. All the data were processed by variance analysis and chi-square test. Results The positive rates of the tumor markers were 89% (87/98) in patients with primary HCC, 19% (13/67) in patients with benign liver disease and 4% (2/46) in healthy individuals. There was statistical difference in the serum level of alpha-fetoprotein (AFP), eareinoembryonic antigen (CEA), ferritin (FER), CA19-9 and CA125 among the 3 groups (F =59.530, 40.472, 31.708, 75. 897, 153.066, P <0.05). Combined detection of AFP, CEA, FER, CA19-9 and CA125 improved the diagnostic accordance rate to 89%, which was significandy higher than the diagnostic accordance rate (64%) when only AFP was detected (X2 = 16.362, P <0.05). The accuracy of the discriminant equation was 90%. Conclusions Combined detection of multi-tumor markers is superior to AFP detection. Combined detection of multi-tumor markers can be used in screening of the HCC patients in HCC high risk population and in the early diagnosis of primary HCC.

Objective To study the efficacy and safety of tacalcitol combined with monochromatic excimer light (MEL) 308 nm vs MEL 308 nm monotherapy in treating vitiligo.Methods Thirty-eight pa- tients with vitiligo were enrolled in the single-blind clinical trial,using plabebo-treated lesions in the same patient as controls.Contralateral or nearby lesions were randomly selected to be treated by either tacalcitol or placebo.All lesions were treated weekly with MEL 308 nm,for a total of 12 sessions.Patients were ex- amined at monthly intervals.The mean number of sessions and the cumulative dosage for initial and excel- lent repigrnentation were calculated.Results Thirty-five patients were evaluated.The mean?SEM cumu- lative dose and number of MEL exposures for initial repigmentation,respectively,were 4.27?3.59 J/cm~2 and 4.89?3.16 on tacalcitol-treated site,5.36?4.12 J/cm~2 and 5.69?3.29 on placebo-treated site,re- spectively (both P＜0.05).For excellent repigrnentation,the cumulative dose and number of exposures were 7.72?5.64 J/cm~2 and 7.79?4.70 respectively on tacalcitol-treated site,and 8.18?4.87 J/cm~2 and 8.4?3.92 respectively on placebo-treated site (both P＞0.05).Treatment with tacalcitol resulted in a sig- nificantly higher percentage (71.4% vs 54.3%) of repigmentation than that with placebo.Conclusions Our results show that MEL 308 nm is safe and effective for the treatment of vitiligo.Additionally,concur- rent topical tacalcitol potentiates the efficacy of MEL 308 nm in the treatment of vitiligo;this combination achieves more rapid pigmentation with a lower total MEL dosage.

The dense extracellular matrix (ECM) of the tumor severely limits the deep penetration of nanomedicine and weakens its anti-tumor effect. Based on this, the yeast vesicle biomimetic nanomedicine with active deep penetration ability of tumor tissue was designed and developed for enhanced tumor therapy. Results of characterization showed that the yeast cell vesicles (YCV) displayed a spherical morphology with diameter of around 100 nm and was well dispersed. Then the chemotherapeutic drug doxorubicin (DOX) was selected as a model drug, and DOX was loaded into YCV to obtain YCV/DOX through electrostatic interaction, the encapsulation efficiencies of DOX were calculated as 82.5%. The drug release profile of YCV/DOX implied that DOX release showed a manner of pH-dependent, it may be that pH has affected the electrostatic effect of YCV and DOX. Compared with liposomes (Lipo), in vitro cell experiments showed that YCV from natural sources had stronger permeability in three-dimensional multicellular spheres. It is speculated that the mechanism may be good deformation capacity of YCV. A 4T1 xenograft tumor model was established to evaluate the therapeutic efficacy of YCV/DOX. The results suggested that YCV/DOX has stronger tumor tissue penetration ability and could effectively inhibit the tumor growth. All animal experiments were performed in line with national regulations and approved by the Animal Experiments Ethical Committee of Zhengzhou University. This study brings new ideas for the development of biomimetic nanomedicine to overcome the ECM of solid tumors.
