OBJECTIVETo evaluate the impact of closed high-pressure suction drainage on the healing of the perineal wound after abdominoperineal resection.

METHODSPatients undergoing rectal abdominoperineal resection in the Wuhan Tongji Hospital from January 2009 to January 2011 were randomized into two groups including the study group(n=61, closed high-pressure suction drainage) and the control group(n=59, presacral drainage). The drainage volume, primary healing rate, and the healing time of perineal wounds were compared.

RESULTSThe total volume of the drainage in the first 3 days was (448.1±142.9) ml in the study group and (548.3±190.6) ml in the control group, the volume of the drainage on the third day was (28.1±12.7) ml and (125.9±84.3) ml respectively. The primary healing rate was 93.4%(57/61) in the study group and 74.6% (44/59) in the control group, the healing time was (13.5±3.5) days and (20.1±5.1) days respectively.

CONCLUSIONClosed high-pressure suction drainage may promote perineal wound healing following rectal abdominoperineal resection.

BackgroundPterygia is a clinical common disease.A lot of surgical methods are developed to decrease the recurrence rate.Resent years,the application of fibrin glue is receiving more and more attention.Objective This study was to explore the effects of fibrin glue in decreasing inflammatory irritation and its mechanism. Methods Pterygia models were created in 12 clean rabbits by exsection of limbal tissue and topical administration of 1.25％ diluted hydrochloric acid,and then the conjunctival autograft surgery was performed in the experimental rabbits.The conjunctival flap was sutured in the left eyes,and the conjunctival wound was closed using fibrin glue in the right eyes.The operation duration for each group was documented and compared.The irritation sign was examined under the slit lamp in all the rabbits 1 week and 4 weeks respectively.The expressions of vascular endothelial growth factor (VFGF) and basic fibroblast growth factor (bFGF) proteins in the conjunctiva tissue were detected by immunochemistry,and the expressions of VFGF mRNA and bFGF mRNA in the conjunctival tissue were determined by reverse transcription polymerase chain reaction (RT-PCR).Results The operative duration was (21.3±0.2) minutes in suture group and( 10.1 ±0.1 )minutes in the fibrin glue group with a significant difference between two groups( t =102.242,P＜0.05 ).From 1 week through 4 weeks,the hyperemiain degree was obviously slight in fibrin glue group compared with suture group.Immunochemistry showed that VEGF and bFGF proteins were expressed mainly in the cytoplasm of conjunctival epithelium layer.The positive response intensity was weaker in the fibrin glue group than in suture group 1 week and 4 weeks after operation.RT-PCR revealed that the expression level of VEGF mRNA was significantly lower in fibrin glue group than in suture group,and the VEGF mRNA was gradually decreased with the time lapse ( Fgroup =174.443,P =0.000 ; Ftime =231.459,P =0.000 ).The similar outcomes were found in the expression of bFGF mRNA(Fgroup=41.727,P=0.000;Ftime=55.417,P=0.000). ConclusionsThe use of fibringluecanshortentheoperationdurationandreducepostoperationinflammatoryreaction.The downregulation of VEGF and bFGF in tissue is the possible mechanism of remitting irritation sign,which allows a reduce of the recurrence rate of pterygia.

Human gut microbiota plays a key role in the development of obesity. Intestinal flora can regulate energy absorption and nutrition metabolism, increasing the energy harvesting from diet. Alteration of gut flora produces excessive lipopolysaccharide, which, when absorbed into the blood, can induce inflammatory reactions and promote the high-fat diet-associated obesity and metabolic syndrome. Intestinal flora increase visceral fat deposition by lowering the expression of Fiaf in intestinal mucosa. Different immune status also affects the intestinal flora.The gut microbiota is hypothesized to be an environmental factor that contributes to obesity; by interacting with factors such as host and diet, it adjusts the energy metabolism. Antibiotics or probiotics may alter the composition of intestinal microflora and improve the metabolic syndrome, and thus provides new treatment options.

Objective To investigate whether elevated pre-procedural C-reactive protein (CRP) and Interleukin-6 (IL-6) concentrations may be relevant to early outcome in patients undergoing PCI.Method 100 consecutive patients undergoing pereutaneuous coronary intervention (PCI) were included in our study.Peripheral blood samples for CRP and IL-6 testing were withdrawn before PCI.Acute vascular complications resulted from PCI were determined by subsequently coronary angiography.The early coronary events during hospitalization were clinically followed.Results Thirty patients developed acute vessel occlusion,and another one developed subacute coronary thrombosis at 2 days after PCI.Increased levels of CRP correlated well with the occurrence of vascular complications as regards the significant difference existing amongⅠvsⅢandⅠvsⅣquartile groups,P

OBJECTIVETo investigate the feasibility of serum pharmacology in evaluating the antitumor effect of Chinese medicine (CM) of Fuzheng Guben (supporting the healthy energy and strengthening the body's resistance to pathogens), the effects of Fuzheng Yiliu Decoction (FYD), a typical prescription of Fuzheng Guben, on proliferation and apoptosis of hepatoma cells in vitro were observed by two methods with serum pharmacology and traditional pharmacology, respectively.

METHODSHepG2 cells were treated with FYD-containing serum or crude FYD extract in vitro. The proliferation rate was determined by methyl thiazolyl tetrazolium (MTT) assay. Cell cycle and apoptosis rate was performed by flow cytometry. And the levels of interleukin-2 (IL-2) and tumor necrosis factor α (TNF-α) in FYD-containing serum were detected by radioimmunoassay.

RESULTSFYD-containing serum remarkably inhibited proliferation and induced apoptosis of hepatoma cells at least by promoting the production of IL-2 and TNF-α in vivo. On the contrary, crude FYD extract promoted the proliferation and did not induce cell apoptosis.

CONCLUSIONThe results by serum pharmacology were accordant with those of our previous animal and clinical trials which indicates that serum pharmacology is a reasonable and feasible method for the evaluation of the antitumor effect of herbs of Fuzheng Guben.
