2 cm). All patients received combination chemotherapy of abdomen and vein with CAP regime and TP regime after sections.Results:Total five year survival rates were 11% in epithelial ovarian carcinoma in stage Ⅲ. The 1-.3-.5-year survival rates of the cases which had less than 4 cycles of chemotherapy were lower than those ≥6 cycles, and the recurrent rates were higher than those ≥6 cycles. The 1-.3-.5-year survival rates of TP regime were higher than those of CAP regime,and the recurrent rates were lower than those CAP regime.Conclusions:There are many relationships between prognosis and residual tumor, nucmber of chemotherapy cycles or regime after resection,which influence results of recurrent ovarian cancer after repeated tumorectomy.

In recent years, pharmacological researches of Chinese medicine have found that single Chinese exterior-relieving medicines such as Pueraria, Semen Sojae Praeparatum and Cimicifuga had very good anti-osteoporosis effect. They can significantly improve the bone mineral density (BMD) and bone mineral content(BMC), promote bone formation, and prevent bone absorption. Based on relative documents from home and abroad, this paper analyzed the current situation and provided new ideas and methods for prevention and treatment of osteoporosis.

PurposeDiffusion weighted imaging (DWI) can significantly improve the diagnosis of non-enlarged lymph node metastasis. This study aims to evaluate the correlation between the DWI findings and the prognosis, and to identify prognostic factors.Materials and Methods Forty-seven patients with colorectal cancer underwent MRI scan including DWI sequence before surgery. Imaging ifndings were compared with the pathologic results to determine the metastatic lymph nodes (DWI positive) or non-metastatic lymph nodes (DWI negative). Postoperative disease-free survival and overall survival for 5 years of the patients with DWI positive and DWI negative lymph nodes were compared. Correlation between the prognosis and the related factors were investigated including regional DWI-positive lymph nodes, short axis diameter and long axis diameter of the largest DWI-positive lymph node, and number of DWI-positive nodes.Results Of 47 patients,10 (21%) patients had regional DWI-positive lymph nodes showed high signal intensity on diffusion-weighted images. The patients with regional DWI negative lymph nodes had a signiifcant better ifve-year disease-free survival and overall survival (P<0.05). The short axis diameter of the largest DWI-positive lymph node was correlated with distant metastasis (AUC=0.77,P<0.05). The short axis diameter and long axis diameter of the maximum metastatic lymph nodes were correlated with overall survival (AUC=0.84 and 0.75,P<0.05). Five-year disease-free survival and overall survival of the patients with short axis diameter of the largest DWI-positive lymph node ≤9 mm were higher than the patients with lymph node short axis diameter >9 mm (P<0.05). Five-year disease-free survival and overall survival of the patients with long axis diameter of the largest DWI-positive lymph nodes ≤11 mm were higher than the patients with long axis diameter >11 mm (P<0.05). Five-year disease-free survival of the patients with all DWI positive lymph nodes resected was higher than the patient without DWI-positive lymph nodes resected (P<0.05).Conclusion The patients with regional DWI-negative lymph node had a better prognosis. Of the patients with DWI-positive lymph nodes, the patients with smaller lymph nodes have better prognosis than who have larger lymph nodes.

Objective　To make a preliminary analysis of orthokeratology(OK) for treating myopia.Methods　OK lenses were chosen to treat myopia with or without astigmatism according to the myopia characterizations, then changes of their visions, refractions, corneal curvature and eccedtricities after being treated for ld, 1、2、3、4 weeks were observed once every 4weeks and were followed up for 18 months.Results　Significant changes were observed after being treated. Slight myopia: the diopters decreased-2.75D±0.50D,the horizontal meridians flattened 1.64±0.21, the vertical 0.92±0.27 and the eccedtricities declined 0.47±0.11; Middle myopia: the diopters decreased -5.50D±0.75D,the horizontal meridians flattened 2.16±0.45, the vertical 1.61±0.67, and the eccedtricities declined 0.38±0.07; High myopia:the diopters did -6.75D±0.50D,the horizontal did 3.86±0.56, the vertical 2.97±0.67 and the eccedtricities did 0.32±0.10.

Objective To investigate the effects and mechanisms of propofol and dexmedetomidine on neurites and synapses of hippocampal neurons neonatal rats, in vitro. Methods Hippocampal neurons of neonatal Sprague-Dawley rats were cultured 6 days, in vitro and were divided into control group (Group C), solvent of propofol group (Group S), propofol group (Group P), dexmedetomidine group (Group D),propofol and dexmedetomidine group (Group PD), and yohimbine group (Group Y). All groups were cultured for 24 h further. Neuron morphology and the expression of protein were measured. Results After exposing to propofol, we found that the mean total length of neurites of primary cultured hippocampal neurons and synapses and the expression of BDNF, TrkB and CRMP-2 protein were reduced; dexmedetomidine played a protective role. Moreover, yohimbine, partly inhibited neuroprotection of dexmedetomidine. Conclusions Propofol decreases the development of neurites and synapses of hippocampal neurons neonatal rats, in vitro, and dexmedetomidine provides a protective effect on propofol by up-regulating the expression of BDNF, TrkB and CRMP-2. The effect, partly has a concern aboutα2-adrenergic agonist.

Heat stroke (HS) is a life-threatening illness characterized by core body temperatures above 40 ℃ coupled with central nervous system (CNS) dysfunction, including delirium, convulsions, and/or coma. Its morbidity has increased dramatically in the past few decades. Multiple organ dysfunction syndrome (MODS) is not only the most serious complication of HS, but also the leading cause of deaths. Understanding the pathogenesis, characteristic and advancement pattern of MODS caused by HS will have a profound effect on the clinical treatment, research and mortality decrease. The pathogenesis, injury characteristic of each system and organ, and treatment methods were summarized in this review so as to deepen the clinical recognition of this disease.

[Abstract ] Objective High-mobility group box-1 (HMGB1) is abundantly released in the epileptogenic brain tissue , but few reports are seen about the effect of HMGB 1 on the expression of P-glycoprotein ( P-gp) in the vascular endothelial cells of the epi-leptogenic tissue .This study is to explore whether HMGB 1 can regulate P-gp expression in the brain microvascular endothelial cells of the mouse in vitro . Methods Immortalized brain microvascular endothelial bEnd .3 cells of the mouse were cultured in vitro and al-located to different concentration groups ( treated with culture medium containing 10 , 100 , 500 , and 1000 ng/mL HMGB1 for 8 hours), treatment duration groups (treated with culture medium containing 100 ng/mL HMGB1 for 4, 8, 16, 24, and 32 hours), and a control group ( treated with culture medium without HMGB 1 ) .The mRNA expression of P-gp-encoding gene-multidrug resistance gene 1a (mdr1a) was detected by real-time qPCR, and its protein expression determined by Western blot and immunocytochemistry . Results The results of qPCR manifested that the expressions of mdr 1a mRNA were 1.646 ±0.176, 1.777 ±0.135, 1.617 ±0.043, and 1.398 ±0.182 in the 10, 100, 500, and 1000 ng/mL HMGB1 groups, respectively, significantly higher than 1.030 ±0.284 in the control group (P<0.05), and so were those in the 4, 8, 16, 24 h, and 32 h groups (2.655 ±0.112, 2.168 ±0.212, 1.823 ± 0.232, 1.418 ±0.376, and 1.445 ±0.123) than in the control (1.010 ±0.164) (P <0.05).Western blot showed a significant increase in the P-gp protein expression in all the concentration groups (P<0.05) as well as in the 8 h and 16 h treatment duration groups as compared with the control group (P<0.05).Immunocytochemis-try also revealed a higher P-gp expression in the HMGB1-treated than in the control cells (P<0.01). Conclusion HMGB1 can upregu-late the expressions of mdr1a mRNA and P-gp protein in the brain microvascular endothelial cells of the mouse , which may associated with drug resistance of central nervous system diseases , especially that of epilepsy .

Objective To observe the roles of nuclear factor-κB (NF-κB) and hypoxia-inducible factor-1 o (HIF-1 α) in hippocampal neurodegeneration of status epilepticus (SE) rats, and explore whether HIF-1α activation is regulated by NF-κB.Methods A total of 110 male Sprague-Dawley rats were randomly divided into seven groups : (1) Control group treated with saline (control, n =15), (2) sham group implanted cannula into lateral ventricle and treated with saline (sham, n =15), (3) SE group treated with pilocarpine (SE, n =20), (4) NF-κB activity inhibitor pyrrolidine dithiocarbamate (PDTC) group treated only with PDTC (PDTC, n =15), (5) SE + PDTC group treated with pilocarpine plus PDTC (SE + PDTC, n =15), (6) SE + HIF-1o siRNA group implanted cannula into lateral ventricle and treated with pilocarpine plus HIF-1 α siRNA (SE + HIF-1α siRNA, n =15), (7) SE + control siRNA group implanted cannula into lateral ventricle and treated pilocarpine plus control siRNA (n =15).SE was induced by injecting lithium chloride and pilocarpine.The seizure of rats was observed.The protein expressions of NF-κB and HIF-1 α in hippocampus of rats were examined by Western blotting.The degenerating neurons in hippocampus were detected by Fluoro-Jade C (FJC) staining.Results Twenty-four hours after termination of SE, the nuclear protein expressions of NF-κB and HIF-1α in hippocampus of rats were increased in SE group (0.57 × 0.06, 0.47 ± 0.07) compared with those in control group (0.23 ± 0.03, 0.20 ± 0.03;P ＜0.05);and compared with SE group PDTC significantly decreased the nuclear protein expressions of NF-κB and HIF-1 α in SE + PDTC group (0.23 ± 0.03, 0.14 ± 0.03;P ＜ 0.05);in SE + PDTC group the numbers of FJC positive cells in CA1 area (28.33 ±5.03) were decreased compared with that in SE group (76.67 ± 13.32);HIF-1 o siRNA injected into lateral ventricle of rats significantly decreased the expression of HIF-1α in hippocampus (0.22 ±0.03) and the number of FJC positive cell in CA1 area (27.34 ±7.02) in SE + HIF-1α siRNA group compared with those in SE group (0.39 ±0.06, 76.67 ± 13.32;P ＜0.05).Conclusions These data suggest that SE can result in activation of NF-κB/HIF-1o pathway in brain.Inhibition of the pathway can attenuate hippocampal neurodegeneration caused by SE, which has the brain protective effect.
