OBJECTIVETo compare the clinical safety and efficacy of laparoscopic versus open colorectal resection in octogenarians. Methods Studies comparing laparoscopic colorectal resection with open colorectal resection in octogenarians were identified from the Medline, Embase, Ovid, and Cochrane databases from 1990 to 2012. The methodological quality of the selected studies was assessed to determine studies suitable for inclusion. Meta-analysis was performed by fixed or random effects model.

RESULTSFive observational studies with a total of 685 patients (330 laparoscopic colorectal resections and 355 open colorectal resections) were identified. Laparoscopic colorectal resection was associated with a prolonged operative time (WMD=27.89, P<0.01) and a lower rate of overall complications (OR=0.58, P<0.01), wound infection (OR=0.50, P<0.05), cardiovascular complication(OR=0.53, P<0.05), quicker bowel function return (WMD=-0.83, P<0.01), and shorter length of hospital stay (WMD=-3.60, P<0.05). No differences were found with regard to anastomotic leak (OR=1.13, P>0.05), prolonged ileus (OR=0.71, P>0.05), respiratory complication (OR=0.59, P>0.05),mortality (OR=0.67, P>0.05), and reoperation (OR=0.85, P>0.05).

CONCLUSIONLaparoscopic colorectal resection is as safe as open colorectal resection, and is more favorable in terms of length of hospital stay and bowel function return in octogenarians.

Recently traditional Chinese medicine (TCM)-induced liver injury has been an unresolved critical issue which impacts TCM clinical safety. The premise and key step to reduce or avoid drug-induced liver injury (DILI) is to identify the drug source of liver injury in early stage. Then the timely withdrawal of drug and treatment can be done. However, the current diagnosis of DILI is primarily governed by exclusive method relying on administering history supplied by patients and experience judgment from doctors, which lacks objective and reliable diagnostic indices. It is obvious that diagnosis of TCM-induced liver injury is especially difficult due to the complicated composition of TCM medication, as well the frequent combination of Chinese and Western drugs in clinic. In this paper, we proposed construction of research pattern and method for objective identification of TCM-related DILI based on translational toxicology, which utilizes clinical specimen to find specific biomarkers and characteristic blood-entering constituents, as well the clinical biochemistry and liver biopsy. With integration of diagnosis marker database, bibliographic database, medical record database and clinical specimen database, an integrative diagnosis database for TCM-related DILI can be established, which would make a transformation of clinical identification pattern for TCM-induced liver injury from subjective and exclusive to objective and index-supporting mode. This would be helpful to improve rational uses of TCM and promote sustainable development of TCM industry.

Inflammatory bowel disease (IBD) has become a common ailment in China in the past decade. At present, the level of diagnosis and treatment of inflammatory bowel disease in China still falls behind Western countries, while the incidence increases rapidly. Chinese IBD Working Group made a new consensus on diagnosis and treatment of inflammatory bowel disease in 2012. This article is to interpret some key issues in the consensus.

The combined application of statins that inhibit HMG-CoA reductase and fibrates that activate PPAR-α can produce a better lipid-lowering effect than the simple application, but with stronger adverse reactions at the same time. In the treatment of hyperlipidemia, the combined administration of TCMs and HMG-CoA reductase inhibitor in treating hyperlipidemia shows stable efficacy and less adverse reactions, and provides a new option for the combined application of drugs. In this article, the pharmacophore technology was used to search chemical components of TCMs, trace their source herbs, and determine the potential common TCMs that could activate PPAR-α. Because there is no hyperlipidemia-related medication reference in modern TCM classics, to ensure the high safety and efficacy of all selected TCMs, we selected TCMs that are proved to be combined with statins in the World Traditional/Natural Medicine Patent Database, analyzed corresponding drugs in pharmacophore results based on that, and finally obtained common TCMs that can be applied in PPAR-α and combined with statins. Specifically, the pharmacophore model was based on eight receptor-ligand complexes of PPAR-α. The Receptor-Ligand Pharmacophore Generation module in the DS program was used to build the model, optimize with the Screen Library module, and get the best sub-pharmacophore, which consisted of two hydrogen bond acceptor, three hydrophobic groups and 19 excluded volumes, with the identification effectiveness index value N of 2. 82 and the comprehensive evaluation index CAI value of 1. 84. The model was used to screen the TCMD database, hit 5,235 kinds of chemical components and 1 193 natural animals and plants, and finally determine 62 TCMs. Through patent retrieval, we found 38 TCMs; After comparing with the virtual screening results, we finally got seven TCMs.

OBJECTIVETo evaluate the effect of emodin in combination with cyclosporine A (CsA) on rejective reaction against liver graft in rats.

METHODSThe LEW-->BN orthotopic liver transplantation rat model was used in the study. A total of 48 rats were divided into 4 groups randomly and equally, after operation they were intraperitoneally injected respectively with normal saline (0.5 mL d(-1), group A); CsA (10.0 mg kg(-1) d(-1), group B); emodin (50.0 mg kg(-1) d(-1), group C); and CsA plus emodin (group D, at the same dose as in B and C). Six rats taken from each group were sacrificed on the 8th day after operation to calculate the rejection active index (RAI) and hepatocyte apoptosis index (AI). The remainder were stopped medication and used for observing the survival time.

RESULTSThe inter-group comparisons in mean survival time, RAI and AI showed significant difference in comparing group A with group B, C and D (P <0.01), and those in group D were more obvious than in group B and C (P < 0.05, but showed no significant difference between group B and group C (P > 0.05).

CONCLUSIONAdministering of emodin combined with CsA after liver transplantation shows a synergistic effect for suppressing acute rejective reaction in rats.

Objective To evaluate the roles of magnetic resonance imaging and proton magnetic resonance spectroscopy(1H-MRS) in the diagnosis of meningiomas. Methods 98 patients with meningiomas underwent conventional pre-contrast MR and contrast MR. Among them, 28 cases had two dimensional single voxel or multi voxel 1 H-MRS simultaneously both in the lesion's region and the contralateral side. Results On precontrast MR images of 98 cases, T1 WI showed 58.1% (61/105) isointensities, 31.4% (33/105) faintly low intensities and 10. 5% (11/105) mixed intensities; T2WI showed 40. 0% (42/105) isointensities, 41.0%(43/105) hyperintensities, 10.5% (11/105) faintly low intensities and 8.5% (9/105) mixed intensities. After administration of Gd-DTPA, the solid part of the tumors exhibited various enhancement in all the 98 cases.28 cases of MRS exhibited specific different spectral peaks, including increased of choline-containing compounds(Cho), absent or decreased of acetylaspartate(NAA), and the unchanged of creatine(Cr). The value of NAA, Cr, Cho, NAA/Cr, Cho/Cr, NAA/Cho in the tumor center of meningioma were 0. 09 ± 0.06,0.31 ± 0. 22, 0.46 ± 0. 16, 0.33 ± 0. 42, 1.50 ± 0. 68, 0. 15 ± 0.08, compared with the contralateral normal region, Cr has no significant difference (P ＞ 0. 05), NAA, Cho, NAA/Cr, Cho/Cr, NAA/Cho had significantly differences(P ＜ 0.05). Conclusion Conventional pre-contrast MR and contrast MR is the most important dignostic means for meningiomas, 1H-MRS combined with MRI can improve the diagnostic accuracy of meningiomas.
