AIM: To evaluate the effect of hexuemingmu tablet on retinal vein occlusion ( ROV) .
METHODS: Totally, 108 patients of 112 eyes were divided into two groups randomly. One group including 55 patients ( 55 eyes ) were treated by hexuemingmu tablet, the other group including 53 patients ( 57 eyes ) were treated by danhong injection. The visual acuity, fundus and FFA were evaluated before and after treatment.
RESULTS: The total effective rate in the group treated by hexuemingmu tablet was 98%, and that in control group was 82%. The hemorrhage was absorbed much more quickly than control group. Two group were different from each other in statistics (P<0. 05).
CONCLUSION: Hexuemingmu tablet can accelerate hemorrhage absorbing and improve visual acuity in RVO treatment.

AIM: To evaluate the role of the meso-hippocampal dopaminergic systems in the generation of hippocampal P300-like potentials. METHODS: Changes of ventral hippocampal P300-like potentials were examined after lesions of the meso-hippocampal dopaminergic systems.The extracellular DA and DOPAC were collected by the push-pull method in the ventral and dorsal hippocampus and their contents were measured by high-performance liquid chromatography with electrochemical detection(HPLC-EC). RESULTS: The contents of DA and DOPAC in the ventral hippocampus were higher than those in the dorsal hippocampus in the normal animals. The peak latencies of P300-like potentials were prolonged and the contents of DA and DOPAC decreased in the ventral hippocampi after lesions of the meso-hippocampal dopaminergic systems. CONCLUSIONS: There exist meso-hippocampal dopaminergic systems in rats;The meso-hippocampal dopaminergic terminals is mainly located in the ventral hippocampal area in rats; The meso-hippocampal dopaminergic projections take part in the generation of the hippocampal P300-like potentials in rats.

Objective To study GFAP changes of astrocyte and expression of Endothelin-1 in molecular pathology in brainstem injury of human being and explore its forensic medical significance. Method 15 brain specimens of acute brainstem injury and 5 brain specimens of no brainstem injury in different time were selected and their microscopic morphological changes were observed with HE staining, and we study the pathological changes of GFAP of astrocyte and expression of Endothelin-1 in monoclonal antibody im-munohistochemistry SP method. Results The number of GFAP positive cells was increased, the bulk of the cell became bigger and expression of Endothelin-1 could be observed. Conclusion The above pathological changes might be a valuable base used for postmortem diagnosis of acute brainstem injury.

Objective To analyze the correlative factors of prognosis of neonatal stress-induced ulcer bleeding.Methods Fifty-four cases of NICU admitted stress-induced ulcer bleeding newborns were divided into mild group and severe group according to bleeding endurance,transfusion requirement,and clinical turnover.Compared with gender,gestational age,birth weight,and score for neonatal acute physiology(SNAP) Ⅱ and score for neonatal acute physiologyⅡ perinatal extension(SNAP-PE) Ⅱ of two groups.Results Based on the output of SPSS statistical package,the SNAP Ⅱand SNAP-PE Ⅱ had a significant deviation between two subgroups((?~2=)15.207,10.311 all P

Objective To clone and compare RNase HIIa and RNase HIIb of Chlamydia pneumoniae AR39(CpRNaseHIIa and CpRNaseHIIb). Methods Genes of CpRNase HIIs were amplified with the designed primers.Then,the recombinant plasmids were constructed,and CpRNase HIIs were expressed and purified with pET expression system.The 5′-32P-labeled RNA/DNA substrate and DNA with oligoribonucleotides substrates were prepared to identify characterization of CpRNase HIIs. Results Ribonuclease H activity of both CpRNase HIIa and CpRNase HIIb could cleave oligoribonucleotides strand,generating break with 3′-OH and 5′-phosphate ends.The results showed that there was different biochemical characterization between them. Conclusion CpRNase HIIa and CpRNase HIIb have different functions in C.pneumoniae.
