OBJECTIVETo discuss the methods for urethral external meatus and glanuloplasty after correction of hypospadias.

METHODSThe V shape flap on the dorsal side of glan, combined with the bilateral glan flaps were moved to the ventral side. The flap at the ventral side of urethral external meatus was turned over. Then the urethral external meatus was repositioned to the top end of glan with the ventral defects covered by the dorsal flaps. Then the coniform glan was reconstructed.

RESULTSFrom January 2008 to December 2013, 28 cases were treated, including glandular hypospadias, postoperative retraction of external urethral meatus and meatal stenosis. 21 patients were followed up for 1 -12 months (average, 1 month) with marked improvement of glan appearance and retraction of external meatus. No meatal stenosis happened.

CONCLUSIONSPostoperative retraction of urethral external meatus and meatal stenosis can be corrected by V shape flap on the dorsal side of glan combined with the bilateral glan flaps. The flat appearance of glan can be improved. It is an ideal method for glandular hypospadias.

In statistical agreement rates of those items to reflect the quality of the guideline, except for rates of "syndrome classification is reasonable" item was 76%, and "recuperating reserve is reasonable" item was 0%, which were referred as not qualified, the rates of the other items were all more than 90%. In statistical application rates of items to reflect the application of the guide, except for the rate of "comparing with expert experiences", the rates of the other items were all more than 90%. Conclusion The general applicability of TCM Clinical Practice Guidelines of Perirectal Abscess is relatively well. The next revised work should uptake not only the experiences of prominent TCM doctors, but also the therapeutic programs of distinctive hospitals and all kinds of research achievements.

Objective To evaluate the nutritional status of iodine of pregnant and lactating women in coastal and inland areas of Zhejiang province,and to provide scientific basis for iodine supplementation.Methods In 2009,five coastal cities,five coastal counties and three inland areas from Zhejiang province were selected by the cluster sampling method,and one sub-district(township) was randomly selected in each city (county),then one community (village) was randomly selected in each sub-district (township).Thirty pregnant women,thirty lactating women and fifty children aged 8 - 10,were randomly selected in each community(village) as the investigation objects to collect instant urine samples to detect urine iodine,and to collect thirty resident edible salt and some water samples to detect salt iodine and water iodine,if the numbers of water source were more than 5 then 1 water sample was collected by their location of east,south,west,north and center in each community(village),otherwise,the numbers of water samples collected were equal to the number of community (village).Results The medians of salt iodine of coastal city,coastal county and inland area were 28.42,25.29,and 33.24 mg/kg,respectively,and the medians of water iodine correspondingly were 5.41,11.52,and 2.80 μg/L,respectively.The medians of urinary iodine of pregnant and lactating women in Zhejiang province were 148.72 and 161.34 μg/L,respectively,which were less than that of children aged 8 - 10(231.02 μg/L,Z =8.57,8.24,all P ＜ 0.017).The medians of urinary iodine in pregnant women from different areas were ranked in order as inland areas(211.42 μg/L),coastal counties (150.51 μg/L) and coastal cities (123.33 μg/L,Z =2.80,5.31,2.42,all P ＜ 0.017),and in lactating women,the medians of urinary iodine in inland areas( 197.43 μg/L) was higher than that in coastal cities( 139.64 μg/L,Z =4.03,P ＜ 0.017).Conclusions The overall levels of iodine nutrition in lactating and pregnant women in Zhejiang province are in the appropriate level,but that of the pregnant women in the coastal cities is inadequate.

OBJECTIVETo explore the activation and proliferation of specific T cells induced by artificial antigen-presenting cells (aAPCs) simulated dendritic cells (DCs) and to observed the effect of these T cells on leukemic cell killing.

METHODSaAPCs were developed by coating a human leukocyte antigen-immunoglobulin fusion protein ( HLA-lg), which was connected each one of the four CML28 antigen epitopes (DLMSSTKGL, DLMSSTKGL, ALFCGVACA, VLTFALDSV), and CD28-specific antibody, to magnet-beads CML cell specific peptides (CML28) served as target peptides. Bone marrow (BM) or peripheral blood (PB) mononuclear cells (MNCs) were isolated from HLA-A2 healthy volunteers, and co-cultured with aAPCs. Specific T lymphocyte were detected by flow cytometry. The fresh acute leukemic cells were used as target cells. The specific T cells incubated with leukemic cells for 4 h at ratios of 5:1, 10:1, 20:1, 40:1, 80: 1, respectively. The effect of leukemic cells killing was detected by lactate dehydrogenase release test.

RESULTSThe average ratio of CML-28 specific T lymphocyte in control group was (2.2 +/- 0.4)% and in experimental groups (DLMSSTKGL, DLMSSTKGL, ALFCGVACA, VLTFALDSV) were (13.5 +/- 1.6)%, (15.2 +/- 1.5)%, (14.7 +/- 1.8)% and (34.3 +/- 3.5)%, respectively, being significantly higher than that in control group (P < 0.01). Induction efficiencies of acute leukemic cells killing were significantly enhanced by increase of effector cells. The cytotoxic activity of specific T lymphocyte in one experimental group (VLTFALDSV) was much higher than that in other three experimental group (P < 0.05).

CONCLUSIONThis "prime and expand" regimen should be an alternative method for large scale amplification of rare tumor-specific CTLs and aAPCs might be a useful tool for leukemia immunotherapy.

OBJECTIVETo assess the prognostic value of metastatic lymph node ratio in gastric cancer patients undergoing radical gastrectomy (D2).

METHODSPrognostic analysis of 1042 gastric cancer patients undergoing radical gastrectomy (D2) was performed based on metastatic lymph node ratio (MLR), the N staging in the 6th and 7th edition of UICC staging system respectively. Homogeneity, discriminatory ability, and gradient monotonicity of these three staging methods were compared using linear trend χ(2), likelihood ratio χ(2) statistics and Akaike information criterion (AIC) calculations, respectively. The area under the ROC curve (AUC) was calculated to compare the prognostic value of these three staging methods.

RESULTSThe 5-year survival rate of 1042 patients was 47.5%. The metastatic lymph node ratio (P<0.01) and N staging of the 7th edition UICC (P<0.05) were independent prognostic factors according to univariate and multivariate analyses. The AUC was 0.754 in MLR staging group, higher than that in N staging of the 6th (0.692) and 7th (0.705) edition of UICC group. Compared to the 6th and 7th edition of UICC N staging group, homogeneity and linear curve were better and AIC value was lower in MLR staging group (7240.017 vs. 7364.073 and 7325.731).

CONCLUSIONPrognostic value of MLR staging is better than that of UICC N staging for patients undergoing radical gastric cancer resection. The MLR staging can be a new method of lymph node staging for gastric cancer patients.

Objective To achieve detailed genomic characterization and investigate the antibiotic-resistant mechanisms of plasmid pA1137 carrying the aminoglycoside resistance gene aacC2.Methods Antibiotic-resistant genes were deter-mined by PCR.Conjugation experiments were performed to verify the transferability of plasmid pA 1137.The minimum in-hibitory concentration(MIC)values of bacterial strains were tested with microdilution method.The genetic background, mobile elements and antibiotic resistance mechanisms of pA 1137 were determined using a whole genome sequencing meth-od.Results Both carbapenem-resistant gene blaIMP-8and aminoglycoside-resistant genes aacC2 and aacA4 were carried by A1137 isolated from Enterobacter cloacae(ECL).aacC2 was located in plasmid pA1137 while the other two resistant genes were observed in chromosomes.Plasmid pA1137 was an IncFⅡplasmid,whose total length was 68.97 kb,and GenBank accession number was MF190369.Plasmid pA1137 contained multiple replicons and intact conjugative transfer regions,so it could be transferred into ECL through conjugation experiments and confer corresponding antibiotic resistance to the transconjugant A1137-EC600.Conclusion IncFⅡ plasmid pA1137 has a single accessory region, the first reported Tn5403-based aacC2-tmrB-related region,which can cause stable inheritance and mediate the resistance to aminoglycoside antibiotics in ECL A1137.

OBJECTIVETo observe the effect of Zhongfengkang on the content of insulin-like growth factor-1 (IGF-1) in brain of focal cerebral ischemia rats.

METHODThe model of focal cerebral ischemia was made by thread-blocking method. In comparison with the curative effect of buchangnaoxintong, the action of Zhongfengkang on infarct volume and the content of IGF-1 in brain of focal cerebral ischemia rats were observed in 6, 12, 24 h and 48 h after cerebral ischemia.

RESULTAs compared with sham operation group, the content of IGF-1 in brain of model group was gradually increased from 6th hour after cerebral ischemia, reaching to the maximal level at 24th hour after the onset of cerebral ischemia (P < 0.01). In comparison with the values in model group at the corresponding time points, the content of IGF-1 in brain of each treatment groups was increased in different extent with a maximal enhancement in the group treated by the high dose of Zhongfengkang (P < 0. 05 or P < 0.01); while the infarct volume of each treatment groups were decreased significantly (P < 0.05 or P < 0.01).

CONCLUSIONZhongfengkang could effectively protect the cerebral tissue from injury of focal cerebral ischemia in the rats through increasing the cerebral content of IGF-1 and reducing infarct volume.

BACKGROUNDThe CRF07_BC recombinant strain has been one of the most predominantly circulated HIV-1 strains in China, it is therefore necessary and urgent to develop a relevant animal model to evaluate candidate vaccines targeting HIV-1 CRF07_BC. A highly replication-competent simian/human immunodeficiency viruses (SHIV) construct containing the Chinese CRF07_BC HIV-1 env gene with the ability to infect Chinese rhesus monkeys would serve as an important tool in the development of HIV vaccines. The aim of this study was to examine whether SHIV XJDC6431 with the env fragment from a Chinese HIV-1 isolate virus could infect the human and monkey peripheral blood mononuclear cell (PBMC), establish infection in Chinese rhesus macaque.

METHODSA SHIV strain was constructed by replacing the rev/env genes of SHIV KB9 with the corresponding fragment derived from the HIV-1 CRF07_BC strain. The infectious activity of the SHIV clones was determined in vitro in PBMCs from both non-human primate animals and humans. Finally, one Chinese rhesus macaques (Macaca mulatta) was infected with one SHIV via intravenous infusion.

RESULTSOne SHIV clone designated as SHIV XJDC6431, was generated that could infect macaque and human PBMC. The virus produced from this clone also efficiently infected the CCR5-expressing GHOST cell lines, indicating that it uses CCR5 as its coreceptor. Finally, the virus was intravenously inoculated into one Chinese rhesus macaque. Eventually, the animal became infected as shown by the occurrence of viremia within 3 of infection. The viral load reached 105 copies of viral RNA per ml of plasma during the acute phase of infection and lasted for 10 weeks post infection.

CONCLUSIONSWe conclude that SHIV XJDC6431 is an R5-tropic chimeric virus, which can establish infection not only in vitro but also in vivo in the Chinese rhesus macaque. Although the animal inoculated with SHIV XJDC6431 became infected without developing a pathologic phenotype, the virus efficiently replicated with a persistent level of viral load in the plasma. This suggested that the SHIV could be used as a tool to test candidate AIDS vaccines targeting the Chinese HIV-1 CRF_07BC recombinant strain.
