5000 copy/ml were both significantly higher than those in the controls.The levels of HBV-DNA positive in cultured supernatants of PBMC from suffering grave hepatitis B were higher than those in the sera by qualitative PCR of the same period.They were similar between the positive rate of quantitative PCR of HBV-DNA in sera and FQ-PCR in cultured supernatants of PBMC from hepatitis B types.They were not obviously related with the levels of ALT and TBiL.Conclusions The IL-12 and ? IFN secretion increased when the HBV-DNA of PBMC from carriers of HBeAg were at high-reproducing state.The HBV-DNA positive rate in cultured supernatants of PBMC of grave hepatitis detected by FQ-PCR was higher than that in sera by qualitative PCR.

Eleven measurements of human up palates from two hundred invividuals were analyzed by the discriminant analysis in order to determine sex.Statistical analysis of the up palate measurements on the sexual dimorphism showed that ten measurements have sex difference(P

Objective To explore the value of application of choledochofiberscopy in the diagnosis and treatment of the extrahepatic bile duct disease, and the effect on reducing the incidence of the postoperative residual stone in biliary ducts. Methods According to the case history and ultrasonography,if the common bile duct(CBD) diseases suspected,the CBD was explored by intraoperative choledochofiberscope(IOCF). During the procedure,a biliary passage mirror inducer apparatus and biliary tract probe which were manufactured by ourselves were used. Results During LC,IOCF was performed on 385 cases of the 10 396 LC cases,and possitive findings were dicovered in 102 cases(26.49%). Among those positive patients, 67 cases belonged to stricture of the lower biliary tract; 5 cases were Mirizzi syndrome; 2 cases were carcinoma of the periampulla; 1 case was primarily carcinoma of the bile duct; 1case was ascarisis of the biliary system. Conclusions IOCF is a good inspect technique with high success rate and clear image of bile duct, it can discover the common duct diseases which are difficult to be diagnosed through the routine examination.At the same time, it can provide the locative and qualitive diagnosis, determine reasonable methods of operation,and effectively provent postoperative complications.

ObjectiveTo investigate the effect of individual donation-nucleic acid amplification test (ID-NAT) and minipool of 16 donations-NAT (P16-NAT) on the results of NAT of blood donors.Methods From February 2009 to June 2009,samples randomly collected from voluntary blood donors in Beijing were tested individually or in pooling of 16 donations by the PROCLEIX ULTRIO assay.For ID-NAT reactive samples with HBsAg,anti-HCV,or anti-HIV serologically unqualified,ID-NAT repeat reactive samples with serologically qualified,and P16-NAT reactive and followed resolution ID-NAT reactive samples,were performed for further discriminatory assays for HIV-1,samples and followed resolution ID-NAT reactive samples,were performed for further discriminatory assays for HBV,HCV and HIV-1discriminatory reagents.Samples which were HBV NAT + alone with serologically qualified were further quantified and confirmed of HBV DNA by Roche HBV quantitative PCR,analyzed by HBV serology and were diluted to simulate if they could be detected in P16-NAT.Results ( 1 ) Among 7613 samples tested by ID-NAT,26 were NAT positive,i.e.the ID-NAT positive rate was 0.34％ ( 26/7613 ). ( 2 ) Among 1004 P16 samples from 16 064 blood donations,27 were NAT positive,i.e.the P16-NAT positive rate was 0.17％ (27/16 064).(3)In serological qualified donations,ID-NAT yield rate (1 in 826,9/7438 ) was much higher than P16-NAT ( 1 in 7875,2/15 750) (x2 =11.880,P ＜ 0.05 ).All these 9 ID-NAT positive and 2 P16-NAT positive donations were discriminated as HBV NAT positive.There were no HCV NAT yield or HIV NAT yield samples. (4) Dilution assay showed only 2 of the 9 (22.22％ ) ID-NAT HBV yields were detected by P16-NAT.(5)Eight ID-NAT and 2 P16-NAT positive samples were quantified for HBV DNA and confirmed as HBV NAT yield,although the virus loads were very low:2 samples had HBV viral loads of 15 IU/ml and 472 IU/ml,6 samples ＜ 12 IU/ml,and 2 could not be detected in the original samples while had ＜ 12 IU/ml and 14.3 IU/ml in the 10 times concentrated samples.(6)Among 11 HBV NAT yield cases,3 (27.3％ ) were possible HBV window-period donors with all HBV seromarkers negative,the other 8 (72.7％ ) had occult HBV infections with anti-HBc or anti-HBe positive,however anti-HBc IgM negative.(7) The rate of initial P16-NAT reactive pools needed to be further tested by ID-NAT was 2.49％(25/1004).Initial P16-NAT reactive pools which caused by serologically qualified donations was 0.20％(2/1004).ConclusionsHBV NAT yield cases are detected at a higher frequency with ID-NAT than P16-NAT.In order to avoid samples with low viral loads would be undetected,NAT assay with high sensitivity should be selected and tested in minimized minipool donations or even with individual donation.

Objective:To investigate the efficacy difference of totally laparoscopic total gastrectomy (TLTG) and laparoscopically assisted total gastrectomy (LATG) on radical gastrectomy for gastric cancer, and further to explore the safety and feasibility of totally laparoscopic esophagojejunostomy.Methods:PubMed, Web of Science, Wanfang and CNKI database were searched for all relevant articles regarding to TLTG versus LATG for gastric cancer published up to September 2019. The search keywords included: gastric/stomach cancer, total gastrectomy, totally/completely laparoscopic, laparoscopic-assisted/laparoscopy-assisted/laparoscopically assisted, esophagojejunostomy/esophagojejunal anastomosis. Meta-analysis was performed with RevMan 5.3 software.Results:A total of 258 articles were retrieved, and 11 studies were finally included after layer by layer screening, with a total sample size of 2421 cases, including 1115 cases in the TLTG group and 1306 cases in the LATG group. There were no statistical difference in age and gender between the two groups, while the mean BMI in the TLTG group was significantly higher than that in the LATG group ( P=0.01). Compared to the LATG group, shorter surgical incision ( P<0.001), less intraoperative blood loss ( P=0.003), larger number of retrieved lymph nodes ( P=0.04), less time to first oral intake ( P=0.03), and shorter postoperative hospital stay ( P=0.02) were found in the TLTG group. There were no significant differences in operation time, anastomotic time, tumor size, proximal resection margin length, postoperative pain score, time to first flatus, rate of postoperative anastomosis-related complication (including anastomotic fistula, stenosis and bleeding) and the overall incidence of postoperative complications ( P>0.05). Conclusions:Totally laparoscopic esophagojejunostomy is safe and feasible, and also suitable for obese patients. TLTG has advantages of minimally invasive, less intraoperative blood loss and easier access to lymph nodes compared to LATG. Totally laparoscopic gastrectomy will probably be the surgical trend for gastric cancer in the future.

Tung tree (Vernicia fordii) is an economically important woody oil plant that produces tung oil rich in eleostearic acid. Here, we report a high-quality chromosome-scale genome sequence of tung tree. The genome sequence was assembled by combining Illumina short reads, Pacific Bio-sciences single-molecule real-time long reads, and Hi-C sequencing data. The size of tung tree gen-ome is 1.12 Gb, with 28,422 predicted genes and over 73％ repeat sequences. The V. fordii underwent an ancient genome triplication event shared by core eudicots but no further whole-genome duplication in the subsequent ca. 34.55 million years of evolutionary history of the tung tree lineage. Insertion time analysis revealed that repeat-driven genome expansion might have arisen as a result of long-standing long terminal repeat retrotransposon bursts and lack of efficient DNA deletion mechanisms. The genome harbors 88 resistance genes encoding nucleotide-binding sites;17 of these genes may be involved in early-infection stage of Fusarium wilt resistance. Further, 651 oil-related genes were identified, 88 of which are predicted to be directly involved in tung oil biosynthesis. Relatively few phosphoenolpyruvate carboxykinase genes, and synergistic effectsbetween transcription factors and oil biosynthesis-related genes might contribute to the high oil content of tung seed. The tung tree genome constitutes a valuable resource for understanding genome evolution, as well as for molecular breeding and genetic improvements for oil production.
