Objective To retrospectively analyze the effect of preemptive treatment on cytomegaloviras (CMV) infection in patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods The data of one hundred and three patients who underwent alIo-HSCT with preemptive treatment to prevent CMV associated diseases were retrospectively analyzed. Fluorescence quantitative PCR was used to detect CMV-DNA. The incidences of CMV viremia and CMV associated diseases were analyzed. Results CMV viremia was confirmed 63 times in 51 of the 103 patients. The incidence of CMV viremia was 49. 5% and the median time of onset was 40 days after transplantation. All the patients with CMV viremia received preemptive antiviral therapy and 19 of them developed CMV associated diseases, including 14 hemorrhagic cystitis, 3 CMV associated pneumonia and 2 CMV associated enteritis. The total incidence of CMV associated diseases was 18. 4%. After treatment with ganciclovir and/or foscarnet, 60 of the 63 times of CMV viremia disappeared. One patient was not included in the analysis because he died of intracranial hemorrhage and GVHD only 3 days after the treatment. The total response rate was 96. 8% (60/62). The remaining two cases who did not respond to treatment died of CMV associated pneumonia in combination with acute GVHD. The direct mortality rate of CMV infection was 1.9% (2/103). Conclusion The incidences of CMV viremia and CMV associated diseases do not increase in patients receiving preemptive therapy as compared with those receiving prophylaxis therapy. Preemptive treatment can not only prevent the progression of CMV viremia to CMV associated diseases in majority of the cases but also control CMV associated diseases effectively.

OBJECTIVETo establish a feasible protocol to provide genetic diagnosis and prenatal diagnosis in Chinese hemophilia patients and their relatives by direct exon sequencing.

METHODSIn our study, genetic diagnosis was performed on 5 unrelated families with informed consent, which included 3 pregnant women who asked for prenatal diagnosis. Umbilical cord blood was obtained from 2 fetuses and amniotic fluid from another fetus. After extraction of the genomic DNA, all of the exons, exon-intron boundaries and their flanks of FⅨ gene were amplified by polymerase chain reaction (PCR). PCR products were detected through direct-sequencing.

RESULTSSequence analysis indicated that the patients and carriers from 5 families have the pathogenic mutations,c.1022G>A (p.R341Q), c.484 C>T (p. R162X), c.1135C>T (p.R379X), c.799C>T (p.H267Y), c.1232G＞T (p.S411I), respectively. Except c.484 C>T (p. R162X), 4 of the 5 mutations were reported firstly in Chinese population. During prenatal diagnosis, one of the fetuses was found to be affected with c.484C>T; p.R162X. The remaining two fetuses were diagnosed as normal, the results of which were later verified by post-birth diagnosis, and factor FⅨ activities in plasma was 52.7% and 76.2%, respectively.

CONCLUSIONIn the quest of strict quality control, exon sequence on FⅨ gene was a rapid and accurate method for genetic diagnosis and prenatal diagnosis of hemophilia B.

Objective To study the alveolar macrophages (AM) activation in neutropenic ARDS in children with hematologic malignancy. Methods Thirteen patients of ARDS were prospectively enrolled into the study and divided into two groups,neutropenic (5 cases) and nonneutropenic (8 cases). Bronchoalveolar lavage fluid (BALF) samples were analyzed for differential and total cell counts, and alveolar activation marker expression (HLA-DR) was determined. Results In neutropenic patients,the BALF total cell count and the macrophage absolute count were significantly lower compared to those in nonneutropenic group ((62. 6 ±9. 6)/μl vs ( 124. 0 ± 6. 7)/μl,P ＜ 0. 01 and (40. 8 ±4. 3)/μl vs (67. 6 ± 10. 7)/μl,P ＜ 0. 01,respectively). As compared with the nonneutropenic group, the percentage of AM in neutropenic patients was significantly higher (65.9% ±9. 0% vs 54. 6% ± 8. 7% ,P ＜0. 05) ,the mean percentage of AM HLA-DR expression was significantly lower (35. 3% ± 5.8% vs 62. 2% ± 5. 8%, P ＜ 0. 01 ). Conclusion These results suggest an alveolar hypocellularity and a deactivation of AM in neutropenic ARDS in children with hematologic malignancy.

Hyperhomocysteinemia, which is an independent risk factor for atherosclerosis, may cause aberrant methylation and dysregulation of gene expression, but the characteristics of the aberrant methylation and its key links involved in its pathogenic mechanisms are still poorly understood. The effect of hyperhomocysteine on DNA methylation in vascular smooth muscle cells, its characteristics and the underlying mechanism of Hcy-induced changing in DNA methylation patterns were investigated. Clinical relevant concentrations of homocysteine was added into the cultured vascular smooth muscle cells of the Homo sapien umbilical vein for 24 h. The level of SAM and SAH was detected by HPLC. The activity of SAH Hydrolase was detected by real-time quantitative reverse transcription-PCR and Western blotting analysis. The level and patterns of DNA methylation were measured by endogenous C-5 DNA methyltransferase(C-5 MT-ase) activity and capacity of genomic DNA to accept methyl groups and methylation-dependent restriction analysis. The results indicated that an increased Hcy concentration induced elevated SAH, declined SAM and the ratio of SAM/SAH, reduced expression of SAH Hydrolase, but increased activity of C-5MT-ase. The methylation status of gDNA analyzed by methyl-accepting capacity of gDNA uncovered a demethylation process in gDNA, or homocysteine-caused hypomethylation in gDNA.With different methylation-dependent restriction endonucleases, the aberrant demethylation was found to prefer C↓CGG sequences to CpG islands. The impacts of different dosage of Hcy showed that the varied detrimental effects of Hcy could be attributed to different concentrations via different mechanisms. In mild and moderate hyperhomocysteinemia, the Hcy may primarily influence the epigenetic regulation of gene expression through the interference of transferring methyl-group metabolism, while in more higher Hcy concentration, the notorious impacts may be more directly caused via oxidative stress, apoptosis, inflammation etc.

Objective To investigate the mechanism and effect of the spinal cord outlet of the skull base on Chiari Ⅰ malformation with syringomyelia.Methods The cervical spinal cord stem angle (Anbc),slope angle of cervical vertebra (Ansc) of Chiari Ⅰ malformation were measured.In foramen magnum (Llf) and anterior vertebral canal level (Laf),spinal canal(Ac),spinal cord (As) and inferior hernia area (Ah) were measured.Angle,area and ratio were compared in Chiari Ⅰ malformation with syringomyelia,Chiari Ⅰ malformation without syringomyelia and normal control group.Results Ansc,Anbc-Ansc had significant differences among control group and Chiari Ⅰ malformation patients (all P＜0.001).In Llf,Laf,As had significant differences among three groups (all P＜0.05),further comparison of the two showed there were significant differences between Chiari Ⅰ malformation with syringomyelia patients and control group,Chiari Ⅰ malformation without syringomyelia patients and control group in Llf(all P＜0.05).In Llf,Laf,Ac in Chiari Ⅰ malformation with syringomyelia was smaller than control group (P＜0.05).Ah in Llf,Lafand Lh in Llf had no statistical significant difference between Chiari Ⅰ malformation with and without syringomyelia patients (all P＞0.05).In Llf,Laf,As/Ac had statistical significant difference among Chiari Ⅰ malformation with and without syringomyelia patients,control group (all P＜0.001),further comparison of the two showed As/Ac in Llf had statistical significance difference between Chiari Ⅰ malformation with syringomyelia patients and control group (P＜0.05),As/Ac in La had statistical significance difference between Chiari Ⅰ malformation with syringomyelia patients and control group,between Chiari Ⅰ malformation without syringomyelia patients and control group (all P＜0.05),Conclusion The cervical spinal cord,Ansc reducing,narrow vertebral proportion increase are important factors to promote Chiari Ⅰ malformation syringomyelia.

Objective To assess the effect of remote-interactive cognitive behavioral therapy in pa-tients with chronic insomnia.Methods A total of 62 patients with chronic insomnia were randomly divided into combined treatment group,cognitive behavioral therapy for insomnia ( CBTI) group and drug treatment group.The study lasted for 6-8 weeks.The curative effects were assessed using sleep diary and scales.Results The sleep onset latency (SOL) ((39.9±23.7)min) and wake time after sleep onset(WASO) ((79.1± 39.4) min) in the drug treatment group were higher than that in the combined treatment group ( ( 25.5 ± 11.2)min and (54.4±38.5)min,respectively) and CBTI group ((27.8±11.6)min and (51.8±29.0)min,re-spectively) at the end of treatment,the difference was statistical significance( P=0.018 and P=0.046 respec-tively).The sleep efficiency(SE) in drug treatment ((76.5±11.9)%) was lower than that in the other two groups((83.8±8.7)%and (82.8±7.0)%respectively),(P=0.042).And no similar difference were seen in TST after treatment(P>0.05).The Brief Version of Dysfunctional Beliefs and Attitudes about Sleep(DBAS-16) score in the drug treatment group (97.6±16.4) was higher than the other two groups((67.5±20.1) and ( 75.0±26.9) respectively) after treatment(P=0.000) .No significant difference was seen in scores of the oth-er scales among the three groups(P>0.05) .After treatment,a greater proportion of patients in the combined treatment group had withdrawn from hypnotics use completely (29%(6/20) vs 5%(1/18);odds ratio( OR ) was 7.286);and the combined treatment group produced significant reduction in frequency of hypnotics use ((3.35±3.05) nights/week) when compared with drug treatment group((5.56±2.33) nights/week, P=0.016) .Conclusions Remote-interactive cognitive behavioral therapy was effective and acceptable for treating pa-tients with chronic insomnia,combining drug treatment in the early period could quickly relieve the symptoms of in-somnia,and can avoid the adverse effect from the hypnotics.And the treatment method can reduce the dropout rate.

Objective To study the endemic trend of schistosomiasis japonica in Hubei Province,so as to provide the theo?retical basis for surveillance and forecasting of schistosomiasis. Methods The time?series auto regression integrated moving av?erage(ARIMA)model was applied to fit the infection rate of residents of Hubei Province from 1987 to 2013,and to predict the shot?term trend of infection rate. Results The actual values of infection rate of residents were all in the 95%confidence inter?nals of value predicted by the ARIMA model. The prediction showed that the infection rate of residents of Hubei Province would continue to decrease slowly. Conclusion The time?series ARIMA model has good prediction accuracy,and could be used for the short?term forecasting of schistosomiasis.

Objective To explore the changing rules of schistosomiasis infection and Oncomelania hupensis snail situation in areas where schistosomiasis transmission was controlled or interrupted or transmission rebounded after the interruption. Meth-ods Daye City,Wuxue City and Jingshan County were selected and investigated retrospectively to collect the schistosomiasis epidemiological information 10 years before they reached the criteria of transmission controlled and the subsequent years until 2008. The database of retrospective investigation was established for analyzing the trends and rules of the changes of snail status and human infection status. Results In Daye City,there was no snail areas and schistosomiasis patients and cattle after reach-ing the criteria of transmission interrupted in 1987. The infection rate of residents were positively correlative with the infection rate of cattle and snail areas(r=0.865,0.843,P<0.01). In Wuxue City,the proportion of snail areas occupying the historic snail areas kept a steady from the transmission controlled to transmission interrupted,but it began to rebound to the highest level in the history(8.93%)after the transmission interrupted for 3 years. In Jingshan County,the infection rates of residents and cat-tle were all stable from 1%to 2%after the transmission controlled. The proportion of snail areas occupying the historic snail ar-eas was rebounded from 1.63% in 1985 to 21.50% in 2008,and the densities of living snails rebounded from 2005. Conclu-sions The infected snails could be the sensitive indicator of the rebound of snail situation and human infection. The elimination of schistosomiasis still depends on the control of snail areas,including strengthening the infected snail control.
