Objective To investigate prophylaxis and therapy of early complications following relatives' partial live small bowel transplantation.Methods Four relatives' partial live small bowel transplantations were carried out.Among the 4 patients,there were 3 cases of short intestine syn- drome and one case of non-function of small bowel caused by the absence of nerve ganglion of small in- testine.More than 4 antigens of HLA were completely matched between donators and receptors.In- testines of donators were got from terminal ileum with the length of (150?10) cm.After operations, tacrolimus (FK506),mycophenolate mofetil (MMF),and methylprednisolone were used to prevent rejections.Measures such as use of anticoagulation,improving microcirculation and albumin infusion, aimed at regulating the function of blood coagulation and preventing bleeding and formation of thrombus at anastomotic stoma;famotidine and omeprazole were used to prevent irritable ulcer;use of the third generation of cephalosporins antibiotics,ganciclovir and fluconazol could prevent bacteria,vi- rus and eumycete infections;disinfection and care of easily-infected organs were emphasized;receptors were encouraged to get out of their beds to move frequently;glutamine and enteral nutrition were used early to promote recovery of intestinal function.Results Three days after operation,one patient's lung was infected with baumanii,and the infection had been under control after being treated with the third generation cephalosporins antibiotics;five days after operation,haematoma was detected on an- other patient and was cleared through the second operations growth of eumycete was found in 2 pa- tients' excretion and secretion from enteron,and their situations were improved with fluconazol;acute rejections of the 4 patients were detected 20 days after operation and reversed by the increased use of FK506 combined with methylprednisolone.Among the 4 patients,2 of them have survived for a long time,and the first patient has survived for 6 years and 8 months till now and the other one for 3 years and 2 months;furthermore,other 2 patients respectively died of infections 5 months and 35 days after the operations.Conclusion Because of special constitution of intestine,early complications of rela- tives' partial live small intestine transplantation are frequent and complicated.Therefore,prophylaxis and therapy of early complications are crucial to the success of the transplantation.

It was widely believed that the interaction between rice and rice blast fungus can be interpreted by the gene-for-gene hypothesis. Two interaction models between rice blast fungus and anti-disease genes had been briefed. They were receptor-ligand model and guard model. The progress of research about molecular marker and position on avirulence genes of the pathogens of rice blast (Magnaporthe oryzae) was reviewed, and the methods to clone and the cloned avirulence genes of rice blast fungus were also summarized.

Background Researches showed that multifocal electroretinogram (mfERG) is able to assess the retinal function in the eyes with acute Vogt-Koyanagi-Harada ( VKH ) syndrome. But the mfERG characteristics of convalescence stage of VKH are still below clear. Objective Present study was to compare and follow up the variation process of visual acuity and mfERG in acute and recovery stages of VKH syndrome. Methods This was a clinic-based retrospective study. Visual acuity, mfERG and fundus fluorescence angiography ( FFA ) were recorded from 35 eyes of 18 acute VKH cases. The period of follow-up in recovery stage lasted about 18 months with the repetitive recording results for 4 times. Results In this study, the visual acuity range in acute stage VKH was 0. 01 to 1.0, and 91.4% (32/35 eyes) was below 0.6. Compared with normal control group, the visual acuity was significantly decreased (P＜0.01). The response densities (amplitudes) of N1 ,P1 waves of the first-order kernel were significantly lowed in all the 6 rings,and the implicit times of 1-4 rings of both waves were significantly prolonged in acute VKH eyes(P＜0. 05). The abnormalities of retinal function showed a regional difference at the posterior pole retina with the dominant change in the first ring,showing a cutting off78% in the P1 amplitude. The abnormal degree of mfERG was more serious as the the increase of retinal eccentricity. In 2 months of convalescence after glucocorticosteroids therapy,the range of visual acuity were 0. 1-1.2 ,and the amplitudes of N1, P1 of 1-2 rings were greatly elevated in comparison with acute on-set (P＜0. 05 ). However, there was still a remarkable difference in the amplitudes of from 1 through 6 rings,comparing with normal. The response density of P1 wave from whole recording region was only 44% of normal. Though the visual acuity was stable during the follow-up duration, a decreasing tendency in N1 and P1 amplitudes were seen. The implicit times of both wave shortened only in 1-3 rings in recovery stages of VKH (P＜0.05). Conclusion VKH syndrome cause serious damage of posterior retinal function.Macular region is the site with greater retinal functional lesion and restore before and after medication. This hardly recovery of retinal function can last over one and half year,even satisfied visual acuity is stable after proper treatment.

The fine structure of enoxaparin sodium samples with different degree of 1,6-anhydro derivatives were analyzed with polyacrylamide gel electrophoresis, high performance liquid chromatography, ultraviolet spectroscopy, infrared spectroscopy and nuclear magnetic resonance spectroscopy. A further study of anticoagulation activity of enoxaparins was performed, including those on their inhibition activities of coagulation factor Xa (FXa) and thrombin (FIIa). The results showed that the anti-FXa and -FIIa activities of enoxaparins with different degree of 1,6-anhydro derivatives (20.0%-39.7%) with similar structure characteristics, had decreasing tendency when the degree of 1,6-anhydro derivatives increased. Especially, the anti-FXa activity was sensitive to the change of the degree of 1,6-anhydro derivatives.

OBJECTIVETo evaluate the efficacy and potential renal impairment of one-year combination therapy de novo of adefovir dipivoxil (ADV) and lamivudine (LMV) for decompensated cirrhosis related to HBV.

METHODSA total of 36 patients with decompensated cirrhosis related to HBV, nobody had nucleos(t)ide analogs (NAs) treatment history, were recruited and were divided into two group (control group and observation group) randomly. A monotherapy of LMV (100 mg per day) was selected to individuals in control group (n = 18), in contrast, a combination therapy de novo of ADV (10 mg per day) and LMV (100 mg per day) was applied to those in observation group (n = 18). Basic approaches including liver protection, symptom-driven intervention, and supporting therapy, were given to all of the individuals. A course of one year was applied to all. Liver function, Child-Pugh score, serum creatinine (sCr) level, virological response (VR) rate, and virological breakthrough rate were observed pro- and post- treatment, differences between the two populations were analysed statistically.

RESULTS(1) The averages of gender, age, HBeAg status, HBV viral load, sCr level, and Child-Pugh score were all compatible in the two groups at baseline (P > 0.05 for all). (2) At the endpoint of treatment, none of deaths was reported. Comparing with the status before treatment in each group itself, liver function, Child-Pugh score, and viral load were improved statistically (P < 0.01 for all), especially in observed group (P < 0.01 for all variables, vs control group), as for VR rate, result is significant superior to that of control group too (88.89% vs 66.67% , P < 0.05). (3) Virological breakthrough occurred to none in observed group and three cases (16.67%) in control group, all of them were confirmed to be rtM204V variant in the following detection of direct sequencing. (4) Elevated level of sCr didn't arised at the end of treatment in two groups.

CONCLUSIONPresent study reveals that in populations with decompensated cirrhosis related to HBV, one-year combination therapy de novo of ADV and LMV is superior to monotherapy of LMV, and the renal safety is favorable within one year.

Objective To evaluate the association of cervical cancer and the G/C single nucleotide polymorphism at codon 72 in p53 gene exon -4 in Chinese population.Methods Literatures were searched in CNKI,VIP,CBM, PubMed,EMBase,the Cochrane Library (Issue 1,2015),WanFang Data Database (1980—2015)with computer. Results Thirteen studies involving 1 780 cervical cancer patients and 1 5 17 healthy volunteers were included.According to the situation of the HPV infection in research object,thirteen studies were divided into two subgroups.The results of meta-analyses in the subgroup of non-HPV infection showed that the Chinese women having the genotype G/G presented no increased relative risk compared to that with the genotype C/C(OR=0.980,95%CI:0.558 -1.723).The allele G showed no increased relative risk compared to the allele C (OR=1.070,95%CI:0.789-1.449)The results of meta-analyses in the subgroup of HPV infection showed that the Chinese women having the genotype G/G presented no increased relative risk compared to that with the genotype C/C(OR=0.891,95%CI:0.213 -3.722).The allele G showed no increased relative risk compared to the allele C (OR =0.981,95%CI:0.493 -1.951 ).Conclusion This meta -analysis demonstrates that G/C single nucleotide polymorphism at codon 72 in p53 gene exon-4 were not associated with cervical cancer in Chinese women.

OBJECTIVETo analyze the expression level of candidate tumor suppressor gene N-Myc downstream-regulated gene 2 (NDRG2) in human colon cancer.

METHODSThirty samples of colon cancer tissues with matched normal colon tissues were collected. The NDRG2 mRNA level was detected by semi-quantitive RT-PCR and the NDRG2 protein level was examined by Western blot and immunohistochemistry.

RESULTSTwelve samples of colon cancer tissues had low NDRG2 mRNA level and low protein level. The positive rates of NDRG2 in normal tissues and the tumorous colon tissues were 90.0%(27/30) and 53.3%(16/30) by immunohistochemistry respectively. There was a significant difference between two groups (P<0.05). The NDRG2 expression was not correlated with age, sex, metastasis of lymph node, depth of infiltration, as well as the Dukes staging(P>0.05), while it was correlated to the histology grading. The positive rate of NDRG2 in the well- and moderate-differentiation group was higher than that in the poor-differentiation group(P<0.05).

CONCLUSIONThe expression of NDRG2 is low in some colon cancer tissues, which indicates that the low level of NDRG2 expression may be engaged in the development of colon cancer.

OBJECTIVETo evaluate the efficacy and adverse effects of transdermal fentanyl in management of patients with cancer pain.

METHODSA total of 4492 patients (aged 3-90) with cancer pain were enrolled in this multicenter study. The mean age was 58.5 (3 approximately 90) years old. All patients received transdermal fentanyl. The patients were asked to record the attacks of pain, quality of life, and any side effects of the treatment.

RESULTSBaseline mean pain intensity was 7.37. On days 1, 3, 6, 9, 15, and 30, the mean scores of pain were decreased to 4.04, 2.98, 2.52, 2.19, 1.85 and 1.61, respectively (P < 0.01). The effective rate was 96.8%. The mean doses of fentanyl were 32.37 microg/h (25-200 microg/h) on the initial day, 42.57 microg/h and 49.57 microg/h (25-225 microg/h) on days 15 and 30. The quality of life was significantly improved after treatment (P < 0.01). The common side effects were constipation (9.8%), nausea (13.6%), dizziness (6.5%), vomiting (3.9%), sedation (2.0%) and respiratory depression (0.2%). The incidence of constipation was related to age, and the incidence of vomiting and difficulty of urination was related to gender. The majority (84.5%) of patients preferred continuation of the treatment with transdermal fentanyl.

CONCLUSIONTransdermal fentanyl for the patients with cancer pain is effective, safe, convenient and can improve the quality of life. Transdermal fentanyl can be recommended as one of first-line drugs for the treatment of patients with moderate to severe cancer pain.

BACKGROUNDEvaluation of fetal central nervous system (CNS) agenesis by ultrasonography (US) is frequently limited, but magnetic resonance imaging (MRI) has its own advantages and is gaining popularity in displaying suspected fetal anomalies. The purpose of this study was to explore the value of MRI in detecting fetal CNS agenesis.

METHODSThirty-four women (aged from 22 to 35 years, average 27 years) with complicated pregnancies (16 - 39 weeks of gestation, average 30 weeks) were examined with a 1.5 T superconductive MR unit within 24 hours after ultrasonography. Half-Fourier acquisition single-shot turbo spin-echo (HASTE) T(2)-weighted imaging (T(2)WI) sequence were performed in all patients, and fast low angle shot (FLASH) T(1)-weighted imaging (T(1)WI) sequence were applied sequentially in seven of them. Comparison of the results was made between the MRI and US findings as well as autopsy or postnatal follow-up MRI findings.

RESULTSThe gyrus, sulcus, corpus callosum, thalamus, cerebellum, brainstem, and spinal cord of fetus were shown more clearly on T(2)-weighted MR images than on T(1)-weighted MR images. MRI corrected the diagnosis of US in 10 cases (10/34, 29.41%) and the diagnosis was missed only in 1 case (1/34, 2.94%).

CONCLUSIONMRI has advantages to US in detecting fetal CNS anomalies and is a supplement to US in complicated pregnancies.

OBJECTIVETo evaluate and compare the results of vagina vasorum lymph node dissection (VLND) and non-vagina vasorum lymph node dissection (NVLND) in patients with gastric cancer after radical operation.

METHODSA total of 759 cases of evaluable patients with gastric cancer, operated from June 1994 to April 2005, were retrospectively analyzed. Of which, 627 cases underwent radical gastrectomy: 215 patients received VLND and 412 cases received NVLND. The operation time, intraoperative blood loss, operative complications and survival rate were recorded and compared between the two groups.

RESULTSThe 5- and 10-year overall accumulative survival rates of VLND group and NVLND group were 55.4% and 51.2%, 39.1%and 36.8%, respectively (all P < 0.05). No significant differences in intraoperative blood transfusion (loss), operation time, operative complication rate was found between the two groups. The 5- and 10-year accumulative survival in patients with a tumor of phase N0-N2, T2-T4, Ib-IV in VLND groups were all significant higher than those in NVLND group.

CONCLUSIONSVLND is a safe technique in advanced gastric cancer, it dose not prolong operation time or increase operative complications but improves survival.
