Objective To investigate the clinical effect of mesocaval shunt and selective coronary vein ligation for portal hypertension caused by cavernous transformation of the portal vein in adults.Methods The clinical data of 26 adult patients with portal hypertensive variceal bleeding caused by cavernous transformation of the portal vein treated by mesocaval shunt plus splenic artery and coronary vein ligation were analyzed retrospectively from 2001 to 2011.Results There was no operative deaths,free portal vein pressure decreased postoperatively,differences were significant before and after shunt (34.4 ± 4.7) cm H2O vs.(24.8 ±2.7) cm H2O,t =12.30,P ＜0.01.Postoperative complications included slight hepatic encephalopathy in 1 case,stress ulcer bleeding in 1 case,which were cured by conservative treatment.23 cases were followed up from 6 months to 4.5 years,and there was no bleeding case.Conclusious Mesocaval shunt plus selective vascular ligation for portal hypertensive variceal bleeding caused by cavernous transformation of the portal vein in adults is safe and effective.

Objective To investigate the short-term efficacy of CT-guided radiofrequency ablation (RFA) for the treatment of advanced non-small cell lung cancer. Methods During the period from June 2010 to June 2013, a total of 100 patients with advanced non-small cell lung cancer were admitted to authors’ hospital. The patients were equally and randomly divided into the study group (n=50) and the control group (n=50). The patients of the control group received concurrent radiotherapy and chemotherapy treatment, while the patients of the study group received CT-guided RFA. The clinical effect, changes in CT values after the treatment, the improvement of physical condition and postoperative complications were recorded, and the results were compared between the two groups. Results The remission rate of the disease in the study group was 86.0%, which was much higher than that in the control group (52.0%), and the difference between the two groups was statistically significant (P<0.05). After the treatment, the CT value of the study group was (14.1±3.9) HU, which was significantly lower than that of the control group (29.8±4.7 HU, P<0.05). The physical improvement rate of the study group (66.0%) was significantly higher than that of the control group (44.0%), the difference between the two groups was statistically significant (P<0.05). The occurrence of postoperative complications, such as pulmonary infection, chest pain, fever, thoracic effusion and gastrointestinal reaction, in the study group was strikingly lower than that in the control group (P<0.05). Conclusion For the treatment of advanced non-small cell lung cancer, CT-guided radiofrequency ablation is safe and less-invasive, it can improve the clinical short-term effect as well as the quality of life. Therefore, this technique should be recommended in clinical practice.

Objective To explore the risk factors on impact of early dislocation after hip arthroplasty,and provide patients with individ-ualized treatment programs. Methods We retrospectively analyzed the clinical data of displaced femoral neck fractures in 247 patients who accepted hip arthroplasty from January 2006 to December 2011,and a total of 8 potential factors associated with occurrence of early dislocation were evaluated by univariate analysis and multivariate logistic regression analysis. Results The univariate analysis showed that sex,surgical approach and femoral head size were correlated with early dislocation (P<0. 05). Multivariate logistic regression analysis showed that female (OR=1. 862),posterolateral surgical approach (OR=3. 478),the use of 22 mm femoral heads (OR=2. 558)were independent risk factors (P<0. 05). And use of≥30 mm femoral heads(OR=0. 635) was a protective factor(P<0. 05). Conclusion Occurrence of early dislo-cation after hip arthroplasty is mainly correlated with many factors,various risk factors should be taken into account in preoperative and intrao-perative and choose the optimal individualized treatment plan.

OBJECTIVE To invesigate the prevalence of SHV-producing Enterobacteriaceae isolates in Hunan Province and identify the subtype of SHV encoding gene and the epidemiological aspect of SHV-producing isolates. METHODS Isolates were collected and identified as well as subjected to ESBLs detection.PCR and DNA sequencing were used to determine the genotype of SHV enzymes.The homology of SHV-producing strains were detected by RAPD. RESULTS Twenty-six of 171 Enterobacteriaceae isolates were confirmed to produce blaSHV genes,and 5 subtypes of SHV-type ?-lactamases were determined,including 9 strains of SHV-28,7 strains of SHV-12,7 strains of SHV-1,2 strains of SHV-11 and 1 strain of SHV-5.There were 6 RAPD types in 19 isolates of SHV-producing Klebsiella pneumoniae,5 RAPD types in 5 isolates of SHV-producing Enterobacter cloacae. CONCLUSIONS SHV-12 is the predominant genotype of SHV ESBLs producing Enterobacteriaceae in Hunan Province,and clone spread has played a certain role in SHV-type ?-lactamase producing K.pneumoniae.SHV ESBLs are not found in Escherichia coli.

Objective To evaluate the expression of WWOX gene in breast cancer and its relation to hypermethylation of WWOX gene CpG island. Methods The expression of WWOX protein was evaluated by immunohistochemical staining in breast cancer cell line and breast cancer tissues.Methylation specific PCR(MSP)was used to check whether it Was methylated in the promoter and exon 1 of WWOX.Results Deletion in the WWOX expression was observed more frequently in invasive breast tumors,(32.2%)than normal breasttissues(5.4%)(P＜0.01).20.3% of premenopause eases were completely negative for WWOX expression compared to 57.2% of postmenopause breast carcinomas(P＜0.01).Furthermore,23.1% of Stage Ⅰ(6/26),28.6%of Stage Ⅱ(10/35),46.2%of Stage Ⅲ(12/26)tunlors showed negative WWOX protein expression.In breast cancer specimens.methylation rate of promoter and exon 1 CpG island of WWOX gene was 55%and 45%respectively.Whereas.WWOX CpG islands of normal mammary tissues were completely unmethylated in all cases.CpG islands of WWOX promoter and exon 1 were methylated in MDA-MB-231 cell line but not MCF-7 cell.Conclusions Some deletion in WWOX expression is common in breast cancer and methylation of WWOX DNA CpG islands plays a crucial role in the silence of WWOX.WWOX may play a role in the carcinogenesis and development of breast cancer.

Objective To evaluate our self-designed guide used clinically in percutaneous placement of lumbosacral pedicle screws in surgery of lumbar vertebral fractures.Methods From May 2012 to March 2015,143 patients with lumbar vertebral fracture were treated with reduction and fixation using percutaneous lumbosacral pedicle screws in our department.Percutaneous placement of lumbosacral pedicle screws was assisted by our self-designed guide in 69 of them(guide group) but not in the other 74 cases (manual group).The 2 groups were compatible in preoperative general data (P ＞ 0.05).The 2 groups were compared in terms of localization time for a single screw,puncture accuracy,times of intraoperative fluoroscopy,operation time,intraoperative blood loss,and hospital stay.Results The guide group had significantly better localization time for a single screw,puncture accuracy,times of fluoroscopy and operation time than the manual group (P ＜ 0.05),but the 2 groups showed no significant differences in intraoperative blood loss and hospital stay (P ＞ 0.05).The guide group obtained an average follow-up of 12.9 months (from 12 to 16 months) while the manual group obtained an average follow-up of 13.2 months (from 12 to 18 months).All fractures healed primarily,without complications like injuries to nerve root or dural sac.Conclusion Our self-designed guide is recommendable because it can obviously improve accuracy of placement of lumbosacral pedicle screws,shorten operation time,and decrease times of intraoperative fluoroscopy.

OBJECTIVETo explore the expression of WT1 gene in leukemia patients and its clinical implications.

METHODSExpression of WT1 mRNA was detected in two leukemia cell lines (K562 and HL-60), 49 acute leukemia (AL) patients, 33 chronic myeloid leukemia (CML) patients and 25 healthy subjects by reverse trans-criptase-nested polymerase chain reaction (RT-Nested PCR).

RESULTSWT1 gene was expressed in all subtype of AL including K562 and HL-60 cell lines, 21/29 newly diagnosed and relapsed AL patients, 1/20 complete remission (CR) AL patients, 15/18 CML blastic crisis patients, 1/5 CML patients in accelerated phase, and 1/10 CML patients in chronic phase. WT1 gene was undetectable in 25 healthy subjects. The expression level of WT1 gene was related to the prognosis of AL, patients with relative level >/= 1.0 had lower CR rates and disease-free survival. For CML patients, WT1 gene expression was associated with the clinical phase, it increased with disease progressed.

CONCLUSIONWT1 gene expression is associated with pathogenesis of leukemia. It is a prognostic factor and a marker for the detection of minimal residual disease in AL and may used as an indicator for diagnosing CML blastic crisis.

Cinnamomum migao plants often face different degrees of drought in karst habitats, which can lead to plants’ death, especially in the seedling stage. Widespread of arbuscular mycorrhizal (AM) fungi in karst soils have the potential to address this drought, which is a threat to C. migao seedlings. We inoculated C. migao seedlings with spores from Glomus lamellosum and Glomus etunicatum, two AM fungi widely distributed in karst soils, to observe seedling growth response after simulated drought. Our results showed that 40 g of G. lamellosum and G. etunicatum significantly promoted the growth of C. migao seedlings, 120 days after inoculation. Following a 15-day drought treatment, root colonization of the seedlings with G. lamellosum or G. etunicatum had lower the accumulation of malondialdehyde (MDA) and increased the accumulation of enzymes and osmotic substances in the seedlings. The relative water content in different organs (roots, stems, and leaves) of the drought-stressed seedlings was higher in plants with G. lamellosum or G. etunicatum than in plants without AM fungi colonization. Our results showed that inoculation with AM fungi was an effective means to improve the drought resistance of C. migao seedlings.
