ObjectiveTo share the experience of arterial plasty and reconstruction of variant arteries in living donor liver transplantation. MethodsFrom September 2006 to May 2010, 73 living donor liver grafts (64 cases using the right lobe,9 cases using left lobe) were used in patients with end-stage liver disease. The hepatic arteries were evaluated preoperatively with computed tomography and magnetic resonance angiography. Back-table arterial plasty was performed under a microscope or a loupe according to arterial variation. We described technical points based on anatomic variations. There were 13 (17. 8 ％) liver grafts with anatomic hepatic arterial variations and all of these cases were subjected to back-table reconstruction with interrupted 8-0 or 9-0 nonabsorbable nylon monofilament sutures according to the diameter of artery. ResultsIn 3 cases, the associate right hepatic arteries that were arisen from superior esenteric arteris (SMA) were reconstructed to cystic arteries. In 2 cases with the associate right hepatic arteries arisen from the abdominal trunk, the right hepatic arteries and associate right hepatic arteries of donors were anastomosed with right hepatic arteries and left hepatic arteries in recipients respectively. In 2 donors, hepatic arteries had branches, which were reconstructed. All of the arterial plasty were conducted on a back table. No arterial thrombosis was found during a postoperative follow-up period of 6 months. ConclusionLive donor liver transplantation using the right lobe with hepatic artery variation can be performed safely, but there is a potential operative risk of severe complication after transplantation. Tominimize operative difficulties and complications, back-table reconstruction should be applied and proper treatment is given according to individual situations to ensure a safe and satisfactory outcome

Objective To explore the clinical value and safety of early enteral nutrition support in patients after liver transplantation.Methods We retrospectively analyzed the clinical data of 86 cases who used early enteral nutrition support therapy after liver transplantation between January 2008and October 2011.All of patients were uproot the gastric tube at the first day after the operation,and gradual to the normal diet.The patients who used parenteral nutrition support therapy were as the control group(n＝112).Then we compared the data of patients in the two groups.Results The early enteral nutrition is more useful to the patients after liver transplantation than intravenous nutrition [In the seventh day after the operation,the control group's ALT was (45.2 ± 12.9) U/L,AST was (40.2±9.4) U/L,ALBwas (35.6±2.5) g/L,P＜0.05].The early enteral nutrition also can decrease hospital stay and hospital costs [(14.2±3.4) d,P＜0.05].Conclusion The early enteral nutrition is useful and safe to the patients after liver transplantation.

Objective To investigate the value of high-resolution magnetic resonance imaging (HRMRI)in diagnosis of extramural vascular invasion (EMVI)of rectal cancer.Methods 33 patients with rectal cancer were reviewed preoperatively.The MRI findings of EMVI of all cases were scored and compared with the postoperative pathological results.Results The MRI EMVI scores were consistent with histopathology findings (k=0.324,P=0.039).The accuracy rate of MRI in diagnosis of EMVI was 66.7% (22/33).The MRI EMVI scores rose up with increased pT stage,meanwhile there was a high correlation between both (r=0.546).The percentage of MRI EMVI positive number was increased with elevated pT stage,and there was also a high correlation between both (r=0.469). ROC curve showed that MRI EMVI scoring was an effective method in diagnosis of rectal cancer EMVI (AUC=0.757).Conclusion HRMRI is a valuable method in diagnosis of EMVI of rectal cancer.

In the present study, the correlated activities of adjacent ganglion cells of transient subtype in response to full-field white light stimulation were investigated in the chicken retina. Pharmacological studies and cross-correlation analysis demonstrated that application of the GABA(A) receptor antagonist bicuculline (BIC) significantly down-regulated the correlation strength while increasing the firing activities. Meanwhile, application of the GABA(A) receptor agonist muscimol (MUS) potentiated the correlated activities while decreasing the firing rates. However, application of the GABA(C) receptor antagonist (1,2,5,6-Tetrahydropyridin-4-yl)methylphosphinic acid (TPMPA) did not have a consistent influence on either the firing rates or the correlation strength. These results suggest that in the chicken retina, correlated activities among neighborhood transient ganglion cells can be increased while firing activities are reduced with the activation of GABA(A) receptors. The GABA(A)-receptor-mediated inhibitory pathway may be critical for improving the efficiency of visual information transmission.

A rapid and accurate method of DNA typing for HLA was established to compensate the unsatisfactory serological typing for HLA before transplantation. DNA typing for HLA using by reverse polymerase chain reaction with sequence-spcific oligo probe (reverse PCR-SSOP) could detect HLA-A(*0101 - 8001) and B(*07021 - 8201). The results showed that HLA-AB alleles were successfully analysed in 60 matching subjects and 16 control DNAs from UCLA by reverse PCR-SSOP without false negtive and false positive results. The results were concordance with those of UCLA. The error rate of serological typing was 6.4% for HLA-A and 7.4% for HLA-B. The serological typing missed HLA-A24 and HLA-B46 for two patients with leukemia respectively. Our results suggest that DNA typing for HLA by reverse PCR-SSOP has proved to be a high-resolution, high-specificity, rapid and accurate technique, suitable for clinical application with a greater precision than serological typing.

OBJECTIVETo observe the efficacy of biased constitution patients treated by auricular point therapy on the basis of "preventive treatment" theory.

METHODSBy means of self-control, 1477 cases of biased constitution were regulated by auricular point sticking therapy or acupuncture, and follow-up and statistical analysis were conducted to observe the efficacy.

RESULTSThere were 322 markedly effective patients, 914 effective patients, 241 failed patients and the total effective rate was 83.7% (1236/1477).

CONCLUSIONThe comprehensive auricular treatment which is easy to operate and acceptable for patients has obvious effect in biased constitution patients. As a new direction of the "preventive treatment" theory, it can be promoted to be a new intervention way of health care.

Objective To evaluate the outcome of living donor liver transplantation(LDLT)for hepatocellular carcinoma(HCC).Methods We retrospectively analyzed the clinical data of 180 patients,who had received LDLT(n=34)or deceased donor liver transplantation(DDLT,n=146)for HCC,compared overall and recurrence-free survival between LDLT and DDLT,and identified the risk factors of tumor recurrence and prognosis by univariate and multivariate analysis.Results The 5-year overall survival and recurrence-free survival rate were 53 % and 58 %,respectively,in DDLT group,and 60 % and 60 %,respectively,in LDLT group.There was no significant difference in overall (P=0.85)and recurrence-free(P=0.89)survival between these two groups.The tumor recurrence rate was 26.5 % in LDLT group,and 17.8 % in DDLT group,respectively(P=0.25).Multivariate COX regression model analysis identified vascular invasion(relative risk 2.118,95 % confidential interval 1.201-4.353,P=0.032)and tumor beyond UCSF criteria(relative risk 3.490,95 % confidential interval 1.862-8.207,P=0.015)as independent risk factors of tumor recurrence,and tumor beyond UCSF criteria(relative risk 8.573,95 % confidential interval 3.016-18.261,P=0.006)as independent predictors of prognosis.Conclusion LDLT is a safe and effective procedure for patients with HCC,but further studies are required for selection criteria of recipients and higher HCC recurrence rate after LDLT.

The clinical efficacy of acupuncture and moxibustion for post-stroke constipation was systematically reviewed. By computerized and manual retrieval of clinical research literature regarding acupuncture and moxibustion for post-stroke constipation, the randomized control trials (RCTs) that met the inclusive criteria were collected. Cochrane systematic review method was used and Revmen 5.2 software was adopted to perform this Meta analysis. Totally 8 articles were included, involving 610 cases of post-stroke constipation. As a result, the total effective rate and cured rate of acupuncture and moxibustion for post-stroke constipation were significantly superior to those of the control group [total effective rate: OR = 2.10, 95% CI (1.25, 3.54), Z = 2.78, P = 0.005; cured rate: OR = 2.37, 95% CI (1.57, 3.58), Z = 4.10, P < 0.0001]. This result indicated that acupuncture was effective for post-stroke constipation and had some advantages compared with other therapies. But the quality of included RCTs was low, and high-quality, large-sample and multi-center RCTs were needed to perform further verification.

Objective To establish a scientific and objective evaluation model of the comprehensive performance of immunocolloidal gold qualitative rapid detection kits, and to provide a reference for the overall evaluation of similar products. Methods Based on the various factors affecting the performance of qualitative rapid detection kits, a comprehensive performance evaluation index system consisting of 4 first-level indicators and 18 second-level indicators was constructed.The analytic hierarchy process (AHP) and the fuzzy comprehensive evaluation (FCE) method were combined to determine the weights for the evaluation indicators and graded thresholds.The model was then used to evaluate the performance level of 6 brands of furazolidone metabolite rapid test kits. Results According to maximum membership degree principle, the evaluation of brand A, B, C, D, E and F were graded as good, excellent, middle, excellent, middle and excellent, respectively.Then the scores of 6 brands were calculated according to the hundred-mark system, and brand B had the highest score.This was consistent with the actual use experience. Conclusion The application of this model can make the evaluation results more comprehensive and accurate, providing reference for rational evaluation and selection of qualitative rapid detection kits.
