In the cultural construction of independent institute,there exist the contradiction between tradition and innovation,cultural conflicts between private enterprises and the university.Therefore,adhering to the people-centered concept,coordinating tradition and innovation,merging the advantages of university culture and private enterprises culture into a whole,cultivating the unique spiritual culture,harmonious system culture and unified material culture of independent institute,forming the distinctive “Institute Culture” with its own cultural tradition will provide reference for the theory and practice to enrich and improve the connotative development of independent institute.

Objective To explore the influence of electrical stimulation on prefrontal cortical neurons and synaptic ultramicrostructure of hypoxic-ischemic brain damage(HIBD)in neonatal rats.Methods The sixty 7-day-old newborn healthy SD rats were randomly divided into hypoxic-ischemic group(model group),electrical stimulation(intervention)group and sham operation group(control group),which 20 for each group.The models of perinatal HIBD rats were prepared by ligation of left common carotid artery with a temporary systemic hypoxia for 2 hours.Intervention group was subject to electric stimulation for 30 minutes,once everyday after surgery.Control group and model group were not subject to electric stimulation but caught to fix in corresponding period.Fastigial nucleus electric stimulations were performed for 3 d,14 d and 21 d.Five rats were killed in each group after the application of electron microscope to observe the brain cortex neurons and synaptic ultrastructure changes.Results In model group,the neuronal shrinkage,the amount of organelles dacrease,ob-vious edema of cytoplasm,obvious swellen mitochondria,and synapse quantity decrease,synaptic space fusion,obvious synaptic vesicle were observed.Intervention group different times,mitochondria hydrops gradually alleviated,synaptic space gradually cleared,synaptic vesicle increased,pathological changes obviously lessened compared to model group at the same time,and there was no apparent abnormality compared with control group on the 21st d.Conclusion Electric stimulation can promote the ultramicrostructures recovery of HIBD rats.

Objective To investigate the effects of electrical stimulation on vascular endothelial growth factor(VEGF) and its receptor expressions of neonatal rat brain with hypoxic-ischemic brain damage(HIBD).Methods Seventy-five 7-day-old newborn health SD rats were randomly divided into sham operation group(control group,n=25),hypoxia-ischemia group(model group,n=25) and the electrical sti-mulation group(intervention group,n=25).To bulid HIBD animal model of neonatal rats,the left common carotid artery was ligated and nitrogen-oxygen gas mixture was inhaled 2 hours.Fastigial nucleus stimulation was given 12 hours after the operation in intervention group,30 min?time-1,1 time?d-1,the time length was 1 d,3 d,7 d,14 d or 21 d,respectively.There was no electrical stimulation in model group and control group.The rats in these groups were captured at the corresponding time.Five rats in each group were killed at the corresponding pe-riods after electrical stimulation,the expression of VEGF and its receptor fam-like tyrosine kinase receptor(flt-1 / VEGFR1),fetal liver kinase receptor(flk-1/KDR/VEGFR2) in hippocampus were observed by immunohistochemistry.SPSS 15.0 software was used to analyze the data.Results The expression of VEGF,VEGFR1,VEGFR2 at every time point in electrical stimulation group were higher significantly than those in model group and control group(Pa0.05).Conclusion Electrical stimulation can promote the expression of VEGF and its receptors VEGFR1,VEGFR2.

OBJECTIVETo explore the clinical application of mandibular-driven simultaneous maxillo-mandihular distraction to correct hemifacial microsomia with rapid prototyping technology.

METHODSThe patient' s skull resin model was manufactured with rapid prototyping technology. The osteotomy was designed on skull resin model. According to the preoperative design, the patients underwent Le Fort I osteotomy and mandibular ramus osteotomy. The internal mandible distractor was embedded onto the osteotomy position. The occlusal titanium pin was implanted. Distraction were carried out by mandibular-driven simultaneous maxillo-mandihular distraction 5 days after operation.

RESULTSThe distraction in five patients was complete as designed. No infection and dysosteogenesis happened. The longest distance of distraction was 28 mm, and the shortest distance was 16 mm. The facial asymmetry deformity was significantly improved at the end of distraction. The ocelusal plane of patients obviously improved.

CONCLUSIONSRapid prototyping technology is helpful to design precisely osteotomy before operation. Mandibular-driven simultaneous maxillo-mandibular distraction can correct hemifacial microsomia. It is worth to clinical application.

ObjectiveTo observe the curative effect of galvanoiontophoresis combined with ultrashort wave therapy on cervical vertebrae disease-derived arrhythmia.Methods112 patients with cervical vertebrae disease-derived arrhythmia were randomly divided into the treatment group and control group with 56 cases in each group. All patients of two groups were treated with antiarrhythmia drug, Sibelium and traditional Chinese medicine. While, the patients of the treatment group were added with galvanoiontophoresis combined with ultrashort wave therapy to eliminate the aseptic inflammation.ResultsThe cure rate and total effective rate of the treatment group were 51.8% and 94.6%. Those of the control group were 16.1% and 76.8%. The effect of the treatment group was better than that of the control group significantly ( P<0.01).ConclusionThe galvanoiontophoresis combined with ultrashort wave therapy has a better effect on cervical vertebrae disease-derived arrhythmia.

OBJECTIVETo study the effect of Guishen Pill (GSP) on expression levels of Oct-4, MVH, and Egr-1 in mice with diminished ovarian reserve (DOR).

METHODSTotally 40 female C57BL/6J mice were randomly divided into 4 groups, the normal control group, the model group, the GSP group, and the dehydroepiandrosterone (DHEA) group, 10 in each group. Pregnant mare serum gonadotropin (PMSG), human chorionic gonadotropin (HCG), and prostaglandin F2α (PGF2α) were sequentially administrated to produce superovulation. The DOR model was established by exposing to ozone inhalation. Mice in the GSP group were intragastrically administered with GSP at 0.3 mL. Those in the DHEA group were intragastrically administered with DHEA at 0.3 mL. Equal volume of normal saline was intragastrically administered to mice in the normal control group and the model group. All mice wer treated for 21 days. Serum levels of estrogen (E2), progestogen (P), and anti-Müllerian hormone (AMH) were measured by ELISA. Changes of Oct-4, anti-AMH, and early growth response gene-1 (Egr-1) mRNA in ovaries were dtected by Real-time PCR.

RESULTSCompared with the model group, serum levels of E2, P, and AMH, as well as contents of estrogen receptor (ER), progestogen receptor (PR), MVH, and Oct-4 mRNA significantly increased in the GSP group and the DHEA group (P < 0.05).

CONCLUSIONGSP could improve expression levels of Oct-4, MVH, and Egr-1 mRNA in DOR mice and their ovarian function.

Chlorogenic acid displays several important roles in the therapeutic properties of many herbs, such as antioxidant activity, antibacterial, antiviral, scavenging free radicals and exciting central nervous system. Only about one-third of chlorogenic acid was absorbed in its prototype, therefore, its gut metabolites play a more important role in the therapeutic properties of chlorogenic acid. It is necessary to consider not only the bioactivities of chlorogenic acid but also its gut metabolites. This review focuses on the potential activities and mechanisms of chlorogenic acid and its gut metabolites on central nervous system diseases.
