Aim To investigate the effect of Rhein derivative 4a containing amide structure on migration and invasion in ovarian cancer SKOV3 cells and its possible mechanism. Methods Ovarian cancer SK0V3 cells were used as target cells. Molecular docking and West-em blot were used to detect the regulatory effect of derivative 4a on Racl protein. CCK8, HE staining, Scratch and Transwell assay were used to detect the effects of derivative 4a on the proliferation, morphology , migration and invasion of SK0V3 cells, respectively. Western blot was employed to determine the expression of matrix metalloproteinases and EMT-related proteins. Results Derivative 4a could effectively bind to Racl protein, and the binding energy was-29. 10 kcal • mol"1, which was significantly lower than that of Rhein; it also could down-regulate the expression of Racl protein in SK0V3 cells. Derivative 4a could significantly inhibit the proliferation, invasion and migra tion of SKOV3 cells, and induce a large amount of cellular vacuolation; derivative 4a could also down-regu-\ late the expression of MMP-2 and MMP-9, up-regulate the expression of EMT epithelial marker protein E-ca-derin but down-regulate the expression of vimentin and j3-cantenin. Conclusions Derivative 4 a can inhibit the proliferation, migration and invasion of ovarian cancer SK0V3 cells. The mechanism may relate to its targeted regulation of Racl, thereby inhibiting the secretion of matrix metalloproteinases, up-regulating the expression of key molecule E-caderin and down-regula-ting the expression of Vimentin and (3-cantenin in EMT i process.•.

Objective To investigate the effect of norepinephrine infusion at 0.03-0.3 μg·kg-1 ·min-1 on renal function in patients undergoing kidney transplantation. Methods Thirty-two ASA Ⅲ or Ⅳ patients aged 22-64 yr weighing 44-88 kg undergoing kidney transplantation were studied. Dialysis was performed within 36 h before operation. Blood pressure was fairly stable. Combined spinal-epidural anesthesia (CSEA) was performed. Spinal anesthesia was performed at L2,3 interspace and hyperbaric 0.5% bupivacaine 10-15 mg was injected into the subarachnoid space. The upper level of sensory block measured by pin-prick reached T6. Epidural catheter was placed at T11,12 interspace and 1% ropivacaine was given intermittently. The patients were randomly allocated into preoperative baseline level (increase or decrease amplitude ＜ 10% of baseline level) by dopamine or norepinephrine infusion during operation. Venous blood samples and urine samples were obtained at the end of operation and 12 h after operation for determination of serum concentrations of cystatin C and β2-microglobulin and urine α1- and β2-microglobulin concentrations. Urine was collected and the volume was recorded. Meanwhile the consumption of furosemide administration during the 12 h after operation was recorded. Results The two groups were comparable with respect to age, M/F sex ratio, body weight, the volume of urine and fluid infused, and the consumption of furosemide. There was no significant difference in serum cystatin C and β2-microgiobulin and urine α1- and β2-microglobulin concentratious, urine volume and consumption of furosemide administration between the transplantation without adverse effect on kidney allograft function.

Objective To explore the clinical significance of dyslipidemia in patients with systemic lupus erythematosus (SLE).Methods By independent-samples t test,serum lipid level was compared between 326 SLE patients and 300 healthy controls.The total cholesterol (TC),triglyceride (TG),lowdensity lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels were partially compared in subgroups of SLE patients.The correlation of serum TC,TG,LDL-C and HDL-C with clinical manifestations and laboratory findings in SLE was analyzed by Pearson or Spearman correlation analysis.Results ①The serum levels of TC [(3.8±1.5) mmol/L],TG [(2.1±1.6) mmol/L] and LDL-C [(2.1±0.9) mmol/L] were significantly higher in SLE group than those of the control group [(3.4±0.6),(0.8±0.4),(1.9± 0.5) mmol/L],and the serum level of HDL-C [(1.2±0.9) mmol/L] was significantly lower in SLE group than that of the control group [(2.0±0.5) mmolFL] (t=4.953,P=0.000; t=14.569,P=0.000; t=3.204,P=0.001; t=-14.335,P=0.000].② The serum levels of TC [(4.0± 1.7) mmol/L],TG [(2.5± 1.7) mmol/L] and LDL-C [(2.2±1.0) mmol/L] were significantly higher in LN group than those of the non-LN group [(3.6±1.0),(1.6± 1.0),(1.9±0.7) mmol/L; t=2.646,P=0.009; t=6.292,P=0.000; t=3.261,P=0.001].③ The serum level of TG [(2.2±1.6) vs (1.8±1.4) mmol/L] was significantly higher in SLE patients with hypocomplementemia than that of the normal ones (t =2.098,P=0.038).The serum level of HDL-C [(1.1 ±0.4) vs (1.6± 1.7) mmol/L] was significantly lower in SLE patients with hypocomplementemia than that of the normal ones (t=-2.375,P=0.020).④ The serum level of TG [(2.3±1.7) vs (2.0±1.4) mmol/L] was significantly higher in anti-dsDNA antibody positive patients than that of negative ones (t=1.989,P=0.048).The serum level of HDL-C [(1.5± 0.4) vs (1.4±1.2) mmol/L] was significantly lower in anti-dsDNA antibody positive patients than that of negative ones (t=-2.979,P=0.003).⑤ The lipid level was correlated with the clinical manifestations and laboratory findings in SLE patients.Conclusion Dyslipidemia exists in patients with SLE and has close correlation with LN,hypocomplementemia and positive anti-dsDNA antibody.

Immunofluorescence histochemistry combined with retrograde tracing technique was employed to observe the effects of masseteric nerve transection on the expression of Trk ( tropomyosin-related kinase) receptor proteins, namely TrkA, TrkB and TrkC in the trigeminal mesencephalic nucleus ( Me5 ) of the rat. At 7 and 14 days following transection of masseteric nerve through which Fluorogold (FG) was applied to identify the Me5 neurons innervating masseter, brain sections were immunohistochemically processed to detect the three Trk isoforms in FG-labeled Me5 neurons. With the percentage of double-labeled neurons to the total number of FG-labeled neurons as the index,we demonstrated ( 1 ) a significant increase in the percentage of TrkA-immunoreactive (IR) Me5 neurons at both 7 and 14 days after nerve transection, (2) no significant, but gradual, increase in the percentage of TrkB-IR Me5 neruons with longer survival time post transection and ( 3 ) little change of TrkC expression. The current findings indicate that axotomy differently affected the expression of the individual Trk receptors and these expression patterns may reflect an adaptation of the Me5 neurons to the peripheral nerve injury.

OBJECTIVE: Embryonic Stem Cell (ES) are characterized by totipotency and normal karyotype and provide the theoretical base in the following fields: embryonic developmeut of mammalian, cell differentiation, expres sion of exogenous genes and utilization of Ess to develop animal model for human inherited diseases. The identification of ES therefore is very important to research and utilize ES.DATA SOURCES: The relevant articles to embryonic stem cell between January 1980 and December 2003 were computer searched for in Medline with the key words "embryonic stem cell, embryo, Alkaline phosphatase,Oct-4"in English. Similarly, the relevant articles to embryonic stem cell between January 1980 and December 2003 were computer searched for in China Journal Full-text Database (CJFD) with the key word "embryonic stem cell" in Chinese.STUDY SELECTION: The articles were browsed firstly. The inclusion criteria were for those articles about the identification of embryonic stem cells. The exclusion criteria were for those about repetitive studies, reviews and other similar articles.DATA EXTRACTION: 16 articles about the identification of embryonic stem cells were collected. Then, the full-texts of the articles were looked through.DATA SYNTHESIS: The selected data were summarized in the following order: ①Preliminary identification of Ess based on morphology and growth;②Immunological valuation; ③Chromosome related identification; ④Identi fication of totipotency and pluripotency.CONCLUSION: The identification of embryonic stem cells is not the result of only one identifying method, but a process of identification. During this process of comprehensive identification, it is recommend to conduct AKP test firstly, karyotype analysis secondly, then examination of surface markers and finally identification of Ess totipotency when Ess are sufficient, takingcare to repeat every identification.
