ObjectiveTo establish a prognostic score model based on preoperative neutrophillymphocyte ratio (NLR) to predict recurrence of hepatocellular carcinoma (HCC) following liver transplantation.MethodsThe clinical data of 76 HCC patients undergoing liver transplantation were retrospectively analyzed.An NLR≥2.5 was considered to be elevated.A preoperative recurrence score was established by using three preoperative factors which significantly increased the risk of tumour recurrence after liver transplantation on multivariate analysis,namely,vascular invasion,tumour number＞3,and NLR≥2.5.We then evaluated the scoring system in predicting tumour recurrence of HCC after liver transplantation.ResultsArea under the receiver operating characteristic curve of preoperative recurrence score was 0.758,with scores of 2 and 3 having hazard ratios of 10.038 and 59.773,respectively.All ten patients with a score of 3 developed tumour recurrence in less than 6 months.The 1-,3- and 5-year tumour-free survival rates for patients with a score of 0,1 and 2 were 95.0％,78.4％,and 78.4％ vs.76.9％,66.9％,and 63.2％ vs.51.9％,8.7％,and 8.7％,respectively.Of 55 patients who had no gross vascular invasion,5 patients with both tumour number＞3 and NLR≥2.5 developed recurrence in less than 31 months.ConclusionsPatients with both preoperative NLR≥2.5 and tumour number more than 3 were at a high risk of tumour recurrence after liver transplantation for HCC.The preoperative recurrence score model strongly correlated with tumour recurrence,and may aid in the selection of patients with HCC for liver transplantation.

BackgroundResearches found that the posterior capsular opacification (PCO) after lensextraction is associated with the elevation of the transforming growth factor-β(TGF-β).To seek the drug for inhibitingproliferation of lens epithelial cells (LECs) is crucial in the treatment and prevention of PCO.ObjectiveThisstudy was to investigate the preventing effects of decorin on the proliferation of LECs.MethodsRabbit LECs wascultured and passaged.The LECs in growth phase were incubated in 96 well plate at the density of 8×106/L.Decorinwith the concentrations 0.1,1.0,10.0 mg/L was added into the medium for 24,48 and 72 hours respectively.0.1％DMSO was used at the same way as positive control group,and the regular cultured cells worked as blank controlgroup.The inhibitory rates of different concentrations of decorin on the growth of LECs were detected by MTT at 24,48and 72 hours after addition of decorin.The percentage of LECs in different cell cycles in various groups was assayedusing flow cytometry.TGF-β level in medium suspension was detected using ELISA.The expression of TGF-β mRNA in LECs was checked by RT-PCR,and α-SMA expression in LECs was determined using immunochemistry.Results ELISA assay showed a statistical difference in the TGF-β levels of different groups (F=39.24,P=0.03 ).The TGF-β levels in 1.0,10.0 mg/L decorin groups were significantly decreased in comparison with blank control group (P＜0.01) and 0.1 mg/L decorin group (P＜0.05 ).The inhibitory rates of decorin in the concentrations of ≥ 1.0 mg/L on the growth of LECs were higher than the blank control group,and those in various concentrations of decorin groups were considerably lower in 24 hours compared with 48 and 72 hours ( P＜0.05 ) and so was the 48 hours compared with 72 hours (P＜0.05 ).The percentages of LECs in G0/G1 phase were ascent in 0.1,1.0 and 10.0 mg/L decorin groups in comparison with G2/M and S phase (P＜0.05).Immunochemistry revealed the weak expression of α-SMA in various decorin groups in comparison with control group. Conclusions Decorin can effectively inhibit LECs growth and induce LECs apoptosis in concentration- and time-dependent manner.It is suggested that decorin can be used in the prevention and treatment of after cataract.

To study the potential effect of Dioscorea nipponica(DN) in intervening peripheral system of rats based on metabolomic analysis. The identification of the potential intervention targets of DN in peripheral system may facilitate its safe application and therapeutic potential exploitation. Totally 20 male SD rats were randomly divided into the blank group and the DN-treated groups, with 10 rates in each group. The DN-treated group was orally administrated with DN extracts once a day for 5 days, with the dose of 80 mg x kg(-1) (equivalent to 15 g crude drug in human), and the blank group was given equal volume of saline once a day for 5 days. Heart, liver, spleen, lung, and kidney tissues and serum samples were collected from each rat 24 h later after the last administration. The ultra-performance liquid chromatography/quadrupole time-of-flight-mass spectrometry based metabolomics was used to investigate the effect of DN in intervening peripheral system of rats. After the treatment with DN, 5 modulated metabolites in heart tissue, 6 in liver tissue, 5 in spleen tissue, 3 in lung tissue, 5 in kidney tissue and 6 in serum sample were identified and considered as the potential intervention targets of DN. Effect of DN in regulating some endogenous metabolites was beneficial for protecting peripheral system, while that in other endogenous metabolites produced potential toxicity to peripheral system. The metabolomic analysis revealed the coexistence of protective and toxic effects of DN on peripheral system, which may be a practical guidance for its safe application and beneficial to the expansion of its application scope.

OBJECTIVETo investigate the efficacy of Chinese medicine Huangban Bianxing Recipe (HBR) for treatment of choroidal neovascularization (CNV).

METHODSEighty patients (97 eyes) suffered from CNV were assigned to two groups, the treated group treated by HBR orally taken one dose every day and the control group treated with ginkgo leaf tablet 1 tablet (19.2 mg) thrice a day, all for 3 months. The best corrected visual acuity (BCVA), fundus hemorrhagic area were measured; the neo-genetic vascular leakage area determined by fluorescent fundus angiography (FFA); and the out-layer high reflective band thickness (OHRBT) estimated by optical coherent tomography (OCT) were recorded before and after treatment.

RESULTSAfter treatment, in the treated group, BCVA was improved, with an effective rate of 67.12%, while in the control group, it was 33.33%, the former was better than the latter significantly (P < 0.05). The effective rate in reducing fundus hemorrhagic area in the two groups (85.11% vs 47.62%) and that in the CNV closure showed by FFA (67.50% vs 37.50%) were also superior in the treated group (P < 0.05). Besides, OCT showed that the OHRBT reduced significantly after treatment in the treated group (P < 0.01).

CONCLUSIONHBR can improve the vision, reduce the CNV leakage in the macular region, and advance the absorption of fundus hemorrhage in CNV patients.

This study is to evaluate the effects of Shenmai injection on the temporal alterations of action potential (AP), early afterdepolarization (EAD) and delayed afterdepolarization (DAD) in papillary muscles. The action potentials were recorded by a glass electrode. APD at 90% repolarization (APD9 ) was measured, and spontaneous EAD and DAD were observed. The results show APD90 was significantly prolonged in model group compared with sham-operated group, whereas it was remained unchanged in Shenmai injec- tion treatment group and amiodarone group. The spontaneous EADs and DADs were frequently visible in model group. In conclusion, EAD, DAD and trigger activities increase gradually during pathological progression of rat cardiac hypertrophy, and Shenmai injection could improve the action potential change in rat cardiac hypertrophy.

Objective To investigate the distribution of surfactant protein-C( SP-C) gene single nu-cleotide polymorphisms and to study the association between the SP-C gene polymorphisms and neonatal respiratory distress syndrome( NRDS) in infants. Methods Fifty-one infants with NRDS( NRDS group) and 51 infants without RDS( control group) were selected. PCR gene analysis and polymerase chain reaction were used to establish the genotype and allele frequencies of SP-C exon 4(T138N) and exon 5(S186N),SP-C exon 4 and 5 for the mutation,and then the association between the polymorphisms and NRDS was analyzed. Results SP-C gene mutations were not found in exon 4 and 5. In the Mongol nationality of the Inner Mon-golia region,SP-C exon 4(T138N) genotypes could check out three genotypes:namely AA,AC and CC. The frequencies of allele A and allele C of SP-C exon 4(T138N) were not statistically different between NRDS group and control group(χ2 =0. 454,P=0. 797). In the Mongol nationality,SP-C exon 5(S186N) genotypes could check out three genotypes:namely AA,AG and GG. The frequencies of allele A and allele G of SP-C exon 5(S186N) were not statistically different between NRDS group and control group(χ2 =0. 493,P =0. 782). Conclusion SP-C exon 4(T138N) and exon 5(S186N) gene polymorphism in Inner Mongolia newborns displays no significant correlation with sex,birth weight or gestational age. SP-C gene mutations are not found in exon 4 and 5. SP-C gene exon 4(T138N) and exon 5(S186N) polymorphisms are not found to be associated with NRDS in Mongol nationality of the Inner Mongolia.

ObjectiveTo study the role of micafungin in the treatment of invasive fungal infection after liver transplantation.MethodsWe retrospectively studied the clinical data of 32 patients who developed invasive fungal infection after liver transplantation treated in our center between December 2008 and June 2010.The therapeutic effect,adverse effect,and the blood concentration/dose ratio of tacrolimus (tacrolimus concentration per dose.kg-1) before and after micafungin treatment were analysed.ResultsThe curative rate was 93.7％.There were no obvious toxicity and sideeffect.The blood concentration/dose ratio in the triazoles treatment group [(1031± 634.2) ng·ml-1/mg · kg-1] was markably higher than the micafungin treatment group [(172.6±39.45) ng·ml-1/mg · kg-1] and the control group (ceasing antifungal agents) [(183.8±47.08) ng· ml-1/mg · kg-1] (P＜0.05).However,there was no significant difference in the blood concentration/dose ratio between the micafungin treatment group and the control group (P＞0.05).ConclusionsMicafungin did not significantly affect the blood concentration/dose ratio of tacrolimus,and effectively treated invasive fungal infection in patients after liver transplantation.

Objective To evaluate the correlations of vascular structures,hemodynamic changes and recanalization before receiving carotid endarterectomy ( CEA) in patients with subtotal or complete occlusion of carotid artery using color Doppler flow imaging (CDFI) and transcranial Doppler (TCD) ultrasonography. Methods A total of 107 patients were diagnosed as subtotal ( stenosis rate 95% to 99%) or complete occlusion of carotid artery with DSA and treated with CEA at Beijing Xuanwu Hospital, Capital Medical University from January 2005 to January 2014 were enrolled retrospectively. The mean age of patients was 61 ± 9 years. According to the findings of DSA,they were divided into either a carotid artery subtotal occlusion group (n=63) or a complete occlusion group (n=44). The vascular diameter,the locations of the lesions ( internal carotid artery or common carotid artery) ,the lumen echo characteristics,and whether internal-external artery collateral circulation patent or not at different stages in patients of both groups were documented. Results The lumen diameter of distal segment was significant wider in patients of the complete occlusion group compared with the subtotal occlusion group (4. 1 ± 1. 1 mm vs. 3. 2 ± 0. 8 mm). There was significant difference between the 2 groups (P <0. 01). There was no significant difference between the location of occlusion and the recanalization rate (P=0. 460). The recanalization rate of the lumen homogeneous echo ( hypoecho and echodense) filling patients (94. 1% vs. 86. 7%) was significantly higher than that of the patients of heterogeneity echo. In patients with complete occlusion of internal carotid artery,the recanalization of CEA would increase when the internal-external collateral arteries were patent. For general comparison,the recanalization rate of the subtotal occlusion group was significantly higher than that of the complete occlusion group (P<0. 01). Conclusion The carotid artery diameter normal or broadening ,the homogeneous echo in the occlusive lumen and the internal-external collateral arteries patency are closely associated with the recanalization rate. The preoperative ultrasonography has great value for the assessment of recanalization of carotid artery occlusive disease after CEA.
