0.05). The mean operation time of the LAVH group was significantly shorter than that of the TLH group [(95.6?18.2) minutes vs (112.9?24.5) minutes, t=-4.883, P=0.000]; whereas, the blood loss in the LAVH group was significantly more than the TLH group [(73.8?50.8) ml vs (49.8?26.9) ml, t=2.926, P=0.004]. Conclusions Laparoscopic hysterectomy is safe and feasible. Both LAVH and TLH have advantages. TLH is more suitable to experienced doctors.

Objective To explore the effect and significance of systemic inflammatory response syndrome(SIRS )score in predicting prognosis in acute craniocerebral trauma. Methods The clinical data of 620 patients were collected at admission from January 2003 to December 2007, GCS and SIRS score were calculated in 24 hours.The relation of the mortality rates and GCS score were analyzed in different SIRS score patients by controlling age. Results With SIRS score increasing,mortality rates increased as well,and pa-tients with SIRS (score≥2) mortality rates had significantly higher,and also in the same age and GCS score group.Mortality rotes were significant in staifistics (P<0.05). Conclusion SIRS score is significant inde-pendent predicting prognosis in acute craniocerebral trauma and in clinic.

Objective To explore the value of prenatal diagnosis and sonographic features of lenticulostriate vasculopathy (LSV). Methods Prenatal ultrasonographic features of three cases of fetal lenticulostriate vasculopathy were retrospectively analysed associated with maternal TORCH screen, fetal magnetic resonance imaging, neonatal physical examination and TORCH screen. Results Prenatal sonographic diagnosis of case 1 demonstrated fetal LSV as well as fetal growth restriction (FGR), periventricular hemorrhage, mitral and tricuspid regurgitation, hydropericardium and catatact. Prenatal sonographic diagnosis of case 2 demonstrated fetal LSV, FGR, periventricular hemorrhage, mitral and tricuspid regurgitation. Prenatal sonographic diagnosis of case 3 showed fetal LSV and intraventricular hemorrhage. Maternal TORCH screens of case 1 and case 3 was negative, while in case 2 was positive. Neonatal examinations of case 1 showed cataract, hearing impairment and congenital infection. Case 3 showed prompted retinal hemorrhage, sinus bradycardia, hyperbilirubinemia and congenital infection. In case 2, maternal teratogenic pathogen screen was positive and the baby did not survive because the mother decided to stop pregnancy in 34 weeks. Conclusions Fetal LSV could be imaged by prenatal ultrasonography. Fetal LSV might indicate intrauterine infection when other abnormalities were accompanied. Ultrasound might be useful for the cases with negative maternal TORCH screen results.

Neural stem cells are a category of cells with self-renewal and differentiation potential. Proliferation and differentiation of neural stem cells have closely relation with growth factor, cell factor, environmental signal, and so on. In recent years, evidence indicates that neural stem cells possessing multipotency naturally occur in adult brain. The found of adult neural stem cells have changed the theory that central nervous system cannot regenerative. Chinese Traditional Medicine can effectively induce adult neural stem cells to proliferate and differentiate, opening up unprecedented direction in the research for the treatment of nerve regeneration, and showing great potency for curing cerebral ischemic injury.

Objective To investigate the effects of Morroniside on H2O2-induced oxidative injury in SH-SY5Y neuroblastoma cells.MethodsSH-SY5Y cells were pre-incubated with Morroniside(1,10,and 100 μmol/L)for 24 h prior to exposure to H2O2(500 μmol/L)for 18 h.The content of reactive oxygen species(ROS),nitric oxide(NO),glutathione(GSH)were determined.ResultsPretreatment the cells with Morroniside(10 and 100 μmol/L)lowered H2O2-induced ROS release by 37%(P<0.01)and 27%(P<0.05)versus H2O2,and NO release in a dose-dependent manner by 31%(P<0.05),53%(P<0.01)versus H2O2.Morroniside(1,10,and 100 μmol/L)increased GSH level in cells treated with H2O2 in comparison with cells exposed only to H2O2,respectively.ConclusionMorroniside shows neuroprotection effect against H2O2-induced oxidation injury in SH-SY5Y cell.

Objective: To analyze and identify the carotenoid in gingko seed.Methods: The chemical composition of the pigment from gingko seed was identified as carotenoid by UV absorption spectrum. Its content was determined by spectrophotometric method and its composition was analyzed and identified by thin-layer chromatography and HPLC method.Results: Gingko contained carotenoids, roughly about 489 ?g/100 g in which lutein, ?-carotene and ?-carotene amounted to 69.20%,15.80% and 7.45% respectively. Conclusion: Gingko contained large quantity of carotenoids, mainly lutein, and next in order ?-carotene and ?-carotene.

Objective To study the impact of physical stimulus on periosteal chondroplasia with an in- tention of reconstructing cartilage tissue that has a biomechanical function and can be created either entirely in vivo or in vitro and subsequently implanted into the patient.Methods A series of biomechanical test methods were designed in order to investigate the mechanical properties of engineered cartilage under a variety of mechanical stress stimulations.The periosteal explants were harvested from proximal medial tibias of New Zealand rabbits and secured onto poly-?-caprolactone(PCL)scaffolds.The composites(periosteum/PCL)were suspended in the spinner flask bioreactor and the spinner flask was located on the stirring machine.The stem cells were stimulated by fluid shear stress under magnetic bar stirring.Results In gross observation,the thickness and length of neo-cartilage with shear force stimulation were significantly greater than those without shear force.The direction of elongation was parallel with fluid flow direction,regardless of composite orientation.Secondary,two different zones based on various cell morphology and distribution were clearly observed.The thickness of the superficial zone was greater in samples exposed to high shear force compared with low shear force.The superficial zone protein and lubricant were found in the engineered cartilage under shear stress stimulation.Conclusion The results reveal that shear stress can not only influence proliferation and differentiation of stem cells,but also change chondrocyte morphology and increase extracellular matrix production.

Objective: To observe the clinical efficacy of acupuncture plus rehabilitation training in treating post-stroke deglutition disorders of qi-deficiency blood stasis pattern. Methods: Sixty-six patients with post-stroke deglutition disorders of qi-deficiency blood stasis patter were divided into an observation group and a rehabilitation group using the random number table method. The two groups both received conventional medications and supportive treatment for stroke. In addition, the observation group received acupuncture plus rehabilitation training while the rehabilitation group only received the same rehabilitation training. The interventions were conducted 3 times a week for a total of 4 weeks in both groups. They were evaluated using Kubota water swallowing test (KWST), Fujishima Ichiro food intake level scale (FILS) and symptoms score of traditional Chinese medicine (TCM) before and after treatment, and at the 1-month follow-up. The therapeutic efficacy was assessed at the 1-month follow-up. Results: The KWST grading and FILS result after treatment and at the follow-up were significantly different from those before treatment in both groups (all P<0.001); the results of these two items at the follow-up were not significantly different from those after treatment in the two groups (all P>0.05). There were significant differences in the KWST grading and FILS result between the two groups after treatment and at the follow-up (all P<0.05). The TCM symptoms score changed significantly after treatment and at the follow-up compared with that before treatment in both groups (all P<0.001). The TCM symptoms grading efficacy at the follow-up was significantly different from that after treatment in the observation group (P<0.05), while the difference was statistically insignificant in the rehabilitation group (P>0.05). The TCM symptoms grading efficacy in the observation group was significantly different from that in the rehabilitation group after treatment and at the follow-up (both P<0.05). Conclusion: Based on the conventional treatment for stroke, acupuncture plus rehabilitation training or use of rehabilitation training alone both can improve the clinical symptoms in post-stroke deglutition disorders of qi-deficiency blood stasis pattern, but acupuncture plus rehabilitation training can produce more significant efficacy and better long-term efficacy in improving TCM symptoms.
