Ex-vivo liver resection and liver autotransplantation offers a chance to cure extensive regional liver diseases which are otherwise deemed untreatable in selected cases. A 33-year-old male patient with advanced alveolar echinococcosis (AE) which invaded the right lobes and adjacent retrohepatic inferior vena cava, while the left lobes were free from lesion and had proliferated to over 1200 ml in size except for a 1 cm × 1 cm solid lesion in the segment Ⅳ. No extrahepatic metastases were found in this patient. A lesion with a size of 4300 ml and other small lesions in the right lobes were removed extracorporeally,and the retrohepatic vena cava was repaired, then the remaining AE-free left lobes (more than 700 ml in size) and the retrohepatic inferior vena cava were re-implanted in situ. A temporary end-to-end cavo-caval shunt with interposition of a blood vessel prosthesis and end-to-side portocaval shunt were established to keep the blood flow during the four-hour anhepatic phase. The patient was followed up for six months, and he had no signs of residual liver disease with good hepatic function.

Background Choroidal neovascularization (CNV) leads to blindness in many fundus diseases.Study showed that naringenin suppresses CNV,but it presents with poor bioavailability because of its poor solubility in water.β-cyclodextrin (β-CD) can increase the water-solubility of drugs, however, whether the inhibitory effect of naringenin on CNV can be improved after clathrated with β-CD remains unclear.Objective This study was to compare the inhibitory effects of naringenin with naringenin/β-CD compounds on CNV in rats.Methods Naringenin/β-CD clathrate compounds were prepared with saturated solution,the solubility of naringenin in water was calculated based on standard curve.Thirty-two male Brown Norway rats were randomized into normal control group, model control group, naringenin group and naringenin/β-CD group.Laser-induced CNV models were created in the right eyes of rats from the model control group, naringenin group and naringenin/β-CD group.Naringenin and naringenin/β-CD clathrate compounds were intraperitoneally injected at a dose of 20 mg/kg in the rats of naringenin group and naringenin/β-CD group since the day after modeling, respectively, once per day for 4 weeks, and equal volume of DMSO was injected in the same way in the model control group.Fluorescein isothiocyanate dextran (FITC-D) was injected via rat hypoglossal vein for the preparation of flatmounts of choroid in the fourth week,and the areas of CNV were measured and compared among the groups.The retinal pigment epithelium (RPE)-choroid-sclera tissues were isolated from the rats, and the relative expression levels of vascular endothelial growth factor (VEGF) , cyclooxygenase-2 (COX-2),phosphatidylinositol-3-kinase (PI3K),p38mitogen-activated protein kinase (p38MAPK), matrix metalloproteinase (MMP)-2, MMP-9 mRNA and their proteins in RPE-choroid-sclera tissue were detected using real-time PCR and Western blot.Results The solubility of naringenin in water increased by 11.8 folds after encapsulated with β-CD.The CNV areas in the model control group, naringenin group and naringenin/β-CD group were (34.56± 1.67), (20.90± 1.47) and (13.20± 1.38) × 103 μm2 , respectively, showing significant reduces in the naringenin group and naringenin/β-CD group compared with the model control group (t =3.973 ,P<O.05;t =5.532, P<0.01) ,and the CNV area in the naringenin/β-CD group was significantly smaller than that in the naringenin group (t =3.605,P<0.05).The relative expression levels of VEGF, COX-2, PI3K, p38MAPK, MMP-2, MMP-9 mRNA and their proteins were significantly declined in the normal control group,naringenin group and naringenin/β-CD group in comparison with the model control group (all at P<0.05).In addition, the expression levels of VEGF mRNA and COX-2 mRNA and their proteins were significantly lower in the naringenin/β-CD group than those in the naringenin group (all at P<0.05).Conclusions The naringenin/β-CD clathrate compounds can improve the water solubility of naringenin and enhance their inhibitory effect on rats CNV.The inhibitory effect of naringenin on rats CNV probably is associated with anti-inflammatory pathway.

Objective To investigate whether Danhong injection can enhance the therapeutic effect of neural stem cell (NSC) transplantation in repairing cerebral ischemia injury by regulating the nuclear factor E2-related factor 2 (Nrf2) signaling pathway. Methods Forty male SD rats were randomly divided into the NSC transplantation group (NSC group), Danhong injection group (DH group), NSC+ Danhong injection group (N+D group), NSC+ Danhong injection group +ML385 group(N+D+M group) and PBS control group (PBS group), 8 rats in each group. All rat models of cerebral ischemia were established by embolization of the middle cerebral artery. Reperfusion was performed at 1.5 h after embolization. All rats in each group received corresponding interventions at 3 d after reperfusion. The neurological function score was evaluated before and 1, 2, 4 weeks after NSC transplantation. All rats were sacrificed at 4 weeks after NSC transplantation. The parameters related to oxidative stress were detected. The expression levels of neuron-specific nuclear protein (NeuN) and von Willebrand factor (vWF) were determined by immunofluorescence staining. Results Before NSC transplantation, the neurological function scores did not significantly differ among different groups (all

To establish a simple, quick and effective method to get a large amount of spider toxin JZTX-26 (35 aa) and JZTX-51 (27 aa) with 3 disulfide bonds each, the mature peptides coding gene fragments were constructed and fused with maltose-binding protein (MBP) tag in an Escherichia coli expression vector pMAL-p2x. The recombinant constructs pMAL-jz26 and pMAL-jz51 were transformed and cultured in E. coli TB1 and BL21 (DE3). After being induced by isopropyl-β-d-thiogalactoside (IPTG), the periplasmic proteins were purified by amylose affinity chromatography and analyzed by SDS-PAGE. The fusion proteins were digested with factor X, and purified by Sizes-Exclusion chromatography and Reversed Phase HPLC. Molecular weights of the purified peptides were obtained by using a MALDI-TOF-TOF mass spectrometer, which were consistent with the theoretical molecular weights. Five milligram of target protein could be purified from 1 L of culture medium. The results indicate that the peptides with three disulfide bonds can be expressed by using the prokaryotic expression system with MBP tag. Our findings suggest the possibility of genetic engineering to obtain large amount of spider peptide toxins.

ObjectiveTo investigate the effect of total alkaloids of Corydalis saxicola on a rat model of lipopolysaccharide(LPS)-induced depression, as well as the pharmacokinetic characteristics of 8 of its major components. MethodTwenty-four male SD rats were randomly divided into normal group, model group, fluoxetine group(10 mg·kg-1) and total alkaloids of C. saxicola group(210 mg·kg-1), with 6 rats in each group. In addition to the normal group, the rats were injected intraperitoneally with LPS to establish the inflammation model of depression, and the drug administration was started 1 week after modeling, and the administration groups were gavaged according to the corresponding dose, and the normal and model groups were intragastric administration with equal volume of distilled water, and the administration was performed along with the modeling. After two weeks of continuous administration, the effect of total alkaloids of C. saxicola on the behavior of depressed rats were tested by sucrose preference, forced swimming and open field experiments, the levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-1β and IL-6 in serum of rats were determined by enzyme-linked immunosorbent assay(ELISA), the histopathological changes of rat hippocampus were observed by hematoxylin-eosin(HE) staining. After the last administration, blood was collected from orbit according to the set time, and ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry(UPLC-QqQ-MS) was established to simultaneously detect the concentrations of dehydrocavidine, tetrahydropalmatine, coptisine, palmatine, jatrorrhizine, berberine, berberrubine and epiberberine in plasma, and drug-time curves were drawn. The pharmacokinetic parameters were analyzed by DAS 2.0 software. ResultCompared with the normal group, the model group exhibited a decrease in sucrose preference rate, total distance traveled in the open field, as well as an increase in swimming immobility time and serum inflammatory factor expression(P<0.01). In contrast, compared with the model group, rats in each administration group showed an increase in sucrose preference rate and total distance traveled in the open field, a decrease in swimming immobility time, and a reduction in serum inflammatory factor expression(P<0.05, P<0.01). Additionally, HE staining results revealed that neurons in the hippocampus of rats from the model group were characterized by loss, disorganization and residual vacuoles, whereas those from the total alkaloids of C.saxicola group displayed an increase in number with orderly arrangement and clear cytoplasm. Pharmacokinetic results showed that the time to peak(tmax) and half-life(t1/2) of the 8 active ingredients were 0.19-2.06 h and 3.71-8.70 h after continuous administration of total alkaloids of C. saxicola. Among them, the area under the curve(AUC0-∞) of tetrahydropalmatine was the highest and the t1/2 was the shortest, and the AUC0-∞ of coptisine, palmatine, jatrorrhizine, berberine, berberrubine and epiberberine were low. The curves of dehydrocavidine, coptisine, palmatine, berberine and epiberberine showed obvious double peak phenomenon. ConclusionTotal alkaloids of C. saxicola can improve the depression-like behavior of rats, inhibit the expression of inflammatory factors in serum, improve the pathological injury of hippocampus, and has the antidepressant effect. Meanwhile, the effective site is absorbed quickly and eliminated slowly in the depressed model rats, and the efficacy is maintained for a long time.
