Objective To explore the clinical significance of the union between marrow smear and marrow biopsy in the myelodysplastic syndrome(MDS) diagnosis. Methods Bone marrow aspirate and smear were initially abtained, then bone tissues encircled drill and section at the same point which is called as. easy one-step technology to 86 MDS patients were analysed. Results In 86 cases of MDS patients, there were 30 cases of hyperplasia extreme degree of reduction by 34.88 %, 56 eases of active, obvious and extremely active active (65.12 %), 43 cases for red RCMD (50.00 %), 32 cases for the granulocyte dysplasia (37.21%), 22 cases for megakaryocyte RCMD (25.58 %) in bone marrow aspiration smears; compared with 15 cases of hyperplasia extreme degree of reduction and the reduction (17.44 %), 71 eases of active, obviously active and extremely active (82.56 %); 16 cases for red RCMD (18.61%), 52 cases for the granulocyte dysplasia (60.47 %), 56 cases for megakaryocyte RCMD (65.12 %) in bone marrow biopsy sections. 66 cases in 86 cases of bone marrow biopsy and bone marrow smear of WHO classification were in line with the rate of 76.74 %.Conclusion The biopsy slide and the puncture smear synchronization observation is more advantageous than the conventional puncture smear morphology observation and combining two method may increase the accuracy in the MDS diagnosis.

Objective To investigate the effect of auxiliary heterotopic partial liver transplantation in treating acute ischemic liver failure. Methods Auxiliary heterotopic partial liver transplantation was performed on pigs.The pigs were divided into two groups.Group I: The host′ liver was preserved in situ, liver artery was ligated, portal vein was constricted,and donor patial right liver was transplanted under the right lobe of the liver of the host.Portal venous blood supply was constructed only, and arterial blood supply was not constructed .Group B:Except both arterial blood supply and portal venous blood supply of the donor liver were constructed, and the other operative procedures were as the same as in Group A. The living condition, liver function, blood supply, pathology and bile secretion of the donor liver were observed. Results The survival rates in Group B before and after operation were higher than that in Group A .Serum bilirubin(SB) after the operation was higher than that before the operation in Group A, but showed no change in Group B.After the operation, SB in Group A was higher than that in Group B. In Group A, the donor liver didn't secret bile,and hepatocytes were necrosis.In Group B, the bile secretion and blood supply of donor liver were good,and hepatocyte of the donor liver were alive and proliferating actively.The hosts' liver was necrosis obviously in both groups. Conclusions Hosts' liver artery ligation and portal vein constriction can result in acute ischemic liver failure.Auxiliary heterotopic partial liver transplantation is effective in correcting liver failure.The good arterial blood supply must be constructed in the donor liver to get good donor liver quality.

Objective To explore and conclude the influence factors of long-term outcomes of mitral valve repair for moderate and severe mitral regurgitation due to myxomatous degeneration.Methods To review the in-patient data and followup outcomes of 261 patients after mitral valve repair for moderate and severe mitral regurgitation due to myxomatous degeneration from Jan 1993 to Jan 2008 in Changhai Hospital of Second Military Medical University.Results There were 7 perioperative deaths and 254 survivors who obtained satisfactory perioperative outcomes.During the follow-up,24 patients were lost and 230 patients were followed up from 36 months to 174 months (77.3 ±30.3) months and follow-up rate was 90.6％.Multivariate Cox regression shows age ≥ 60 years old,left ventricular ejection fraction ＜ 0.50,undergoing combined coronary artery bypass grafting were the independent risk factors for long-term death after operations and left ventricular ejection fraction ＜ 0.50,New York Heart Association functional classification Ⅲ-Ⅳ,anterior leaflet prolapse were the independent risk factors for long-term recurrent moderate or severe mitral regurgitation after operations and prosthetic ring or band annulopasty was a protective factor.Conclusion The age ≥60 years old,left ventricular ejection fraction ＜ 0.50,undergoing combined coronary artery bypass grafting,New York Heart Association functional classification Ⅲ - Ⅳ,anterior leaflet prolapse,and prosthetic ring or band annulopasty were closely related with long-term adverse events after operations.

Objective To investigate the short term effect of licartin transarterial infusion in combination with chemoembolization (LTACE) and compare its effect with conventional transcatheter arterial chemoembolization (TACE) for advanced hepatocellular carcinoma (HCC).Methods Seventy-two cases of advanced HCC were included in this analysis.There were 50 males and 22 females with the average age of (58±12) yrs (range 34-86 yrs).Twenty-nine patients received LTACE treatment while the other forty three patients received conventional TACE treatment.Before intervention,there was no variation (P>0.05) in gender (X2 =0.202),Child-Pugh grading for hepatic function (X2=2.428),as well as in white blood cell count (t=1.101)and platelet count (t =0.080) between the two groups except for age and portal vein thrombosis.For LTACE group,30 minutes after the infusion of licartin (27.75 MBq/kg) into proper hepatic artery,an emulsion of 40 rag pharmorubicin and 30 ml uhrafluid lipidol was infused until hemostasis within target artery.For TACE group,only an emulsion of 40 nag pharmorubicin and 30ml uhrafluid lipidol was infused until hemostasis within target artery.Following these interventions,the two groups were given the same treatment to stabilize hepatic function and relief embolization-relating symptoms; Patients' follow-up included clinical symptoms and signs,hepatic and renal function,peripheral blood test,CT and radionuclide study(ECT).All data were analyzed with SPSS 11.5.Measurement data were expressed with mean and processed by t test; numeration data were processed by Chi square test and Fisher precise test; Kaplan-Meier analysis and log-rank test were applied for comparing the survival rate of the two groups.P <0.05 means the exist of a statistic variation.Results After treatment,there was no variation of Albumin,GPT,serum bilirubin,white blood cell,platelet and serum creatinine level between the two groups [t=0.250,0.907,0.629,0.005,0.250,0.453 (7 days) and 0.978,1.250,1.942,0.733,0.315,1.243 (14 days); P >0.05].ECT imaging demonstrated a 55.17% (16/29) uptake ratio of licartin within tumor areas by the time of 7-days follow-up study.The lesions in both LTACE and TACE groups exhibited a decrease in their size and statistically significant difference was demonstrated before and after treatment in either group( t=7.207,8.006,P <0.01).But between the two groups,the tumor size reduction showed no statistical difference,the tumor size in LTACE and TACE groups were( 1.68±0.32),(1.74±0.31)respectively (t =0.786,P>0.05)before treatment and(1.52±0.38),(1.61±0.36) respectively(t=0.891,P>0.05) after treatment.There was no variation between the two groups comparing the 6 months cumulative survival rate(LTACE 52%,TACE 76%,log-rank test,X2=3.080,P >0.05).Conclusion There was no statistically significant differences between LTACE and TACE groups concerning the short term effect and adverse reaction for treatment of advanced HCC.The long term outcomes should be established on the basis of a large-sample,multiconter,randomized trail.

Objective To analyze the basic clinical characteristics,auxiliary diagnostic indexes,bacterial infection spectrum and drug resistance of child urinary tract infection to provide the basis for the prevention,diagnosis and treatment of child UTI.Methods The clinical data in the inpatients with UTI or complicating UTI in our hospital from January 2012 to March 2014 were collected. The repeated strains were excluded.The differences in the pathogens between the patients with complicated UTI and the patients with non-complicated UTI were comprehensively analyzed.Results The onset peak of child UTI for the first time was 0 -0.5 years old.Escherichia coli ,Klebsiella and Pseudomonas aeruginosa are the major pathogens of child UTI,in which 110 strains were Escherichia coli,accounting for 52.9%.The enterobacteriaceae pathogens of UTI had higher sensitivity to carbapenems antibacterial drugs,with the resistance rate of less than 10%;the resistance rate of others detected antibacterial drugs was more than 20%.Con-clusion UTI in the children inpatients of this area has higher drug resistance rate,in the treatment of child UTI,the antibacterial drugs should be rationally used by combining the bacterial drug resistance situation in the local place and the disease severity in or-der to avoid the aggravation of bacterial drug resistance.

Objective:To investigate the regulation of transcription factor CCCTC binding factor (CTCF) on the expression of B-cell lymphoma 2 ( Bcl-2) gene in pterygium and its molecular mechanism. Methods:Pterygium tissue samples from 22 primary pterygium patients who underwent pterygium excision combined with autologous limbal stem cell transplantation in The First Hospital of Changsha from June 2017 to February 2019 were collected during the operation as pterygium group.Normal conjunctival tissue from 20 patients with ocular trauma due to conjunctiva rupture, eyeball rupture or eyeball perforation in the same period were collected during the repair of ocular trauma as control group.Real-time PCR and Western blot were used to detect the expression levels of CTCF and Bcl-2 in the two groups.The DNA methylation level of the Bcl-2 promoter in the samples of the two groups was detected by bisulfite sequencing PCR (BSP). Pterygium fibroblasts were isolated and cultured.Fibroblasts were identified by immunohistochemistry using vimentin antibody.The cultured pterygium fibroblasts were divided into a CTCF interference group transfected with CTCF interference plasmid, and a control group transfected with control plasmid.The expression levels of CTCF and Bcl-2 in pterygium fibroblasts in CTCF interference and control groups were detected by real-time PCR and Western blot.The cell vitality was detected with cell counting kit-8 at 12, 24, and 48 hours after transfection.The DNA methylation level of the Bcl-2 promoter in the cells of the CTCF interference and control groups after transfection was determined by BSP.Differences of the indexes among groups were analyzed.Correlation between Bcl-2 mRNA and Bcl-2 gene promoter methylation level of CTCF protein in pterygium tissue was analyzed by Pearson linear correlation analysis.This study protocol was approved by the Ethics Committee of The First Hospital of Changsha (No.KL-2017021). Written informed consent was obtained from the patients from whom the specimens were collected.Results:The relative expression levels of CTCF mRNA and protein in pterygium group were 7.23±3.34 and 0.92±0.21, respectively, which were significantly higher than 1.10±0.44 and 0.28±0.07 in normal conjunctiva group ( t=-8.136, -13.025; both at P<0.01). The relative expression levels of Bcl-2 mRNA and protein in pterygium group were 10.27±4.64 and 0.95±0.27, which were higher than 1.10±0.41 and 0.32±0.14 in normal conjunctiva group, showing statistically significant differences ( t=-8.789, -10.782; both at P<0.01). The CTCF protein expression was significantly positively correlated with the Bcl-2 mRNA expression in pterygium group ( r=0.746, P<0.01). The DNA methylation level of the Bcl-2 promoter in pterygium group was 0.65±0.09, which was lower than 0.83±0.06 in normal conjunctiva group, with a statistically significant difference ( t=7.408, P<0.01). The DNA methylation level was significantly negatively correlated with the Bcl-2 mRNA expression in pterygium group ( r=-0.635, P<0.01). After the interference of CTCF expression in pterygium fibroblasts, the relative expression levels of CTCF and Bcl-2 mRNA in CTCF interference group were 0.37±0.03 and 0.53±0.06, which were significantly lower than 1.02±0.06 and 0.99±0.07 in control group ( t=20.035, 9.029; both at P<0.01). The relative expression levels of CTCF and Bcl-2 proteins in CTCF interference group were 0.23±0.06 and 0.56±0.07, which were lower than 0.52±0.05 and 0.92±0.12 in control group, showing statistically significant differences ( t=6.914, 4.719; both at P<0.01). The cell viability of pterygium fibroblasts in CTCF interference group was 0.10±0.01, 0.17±0.01, 0.38±0.04 at 12, 24, and 48 hours after interference, respectively, which were lower than 0.12±0.01, 0.29±0.01 and 0.85±0.06 in control group, and the differences were statistically significant ( t=3.718, 18.350, 15.621; all at P<0.01). The DNA methylation level of Bcl-2 promoter in CTCF interference group was 0.75±0.04, which was significantly higher than 0.61±0.03 in control group ( t=-4.472, P<0.05). Conclusions:CTCF is excessively expressed in pterygium, which may mediate the overexpression of Bcl-2 through down-regulating DNA methylation level.
