Chongqing Medicine 2013;(33):4004-4006
Objective To investigate the association between genetic variants of rs 12425791 on chromosome 12p13 and the one year risk of stroke-related death or recurrent stroke following initial stroke .Methods A total of 401 acute ischemic stroke(AIS) patients who had first-ever ischemic stroke were analyzed .The genotypes of chromosome 12p13 rs12425791 were analyzed by PCR-RFLP .Logistic regression analysis was used to assess the effect of individual genotype on stroke-related mortality or recurrent stroke in one year .Results Among the 401 AIS patients ,31 died or developed a recurrent stroke .After adjustment for age ,sex and vascular risk factors ,logistic regression analysis indicated that the odd ratio were 2 .602(95% CI 1 .216-5 .564) for individuals with homozygous variant allele of rs12425791 .Conclusion This study found that genetic variants of rs12425791 on chromosome 12p13 are independent predictors of stroke-related mortality or stroke recurrence in patients with incident ischemic stroke .

Objective To discuss microvessel density (MVD) and expression of vascular endothelial growth factor(VEGF), androgen receptor(AR) in the prostates of men who received re-operation after TURP. Methods Fifty cases were performed re-TURP (re-TURP group) and the remaining 50 cases served as controls. 150 specimens were collected. Sections were stained for CD34 and VEGF, AR by immuno-histo-chemistry(S-P). Statistical analysis of the results was performed using t-test or Pearson Chi-Square test Results The expression of VEGF, AR and MVD were significantly higher in the re-TURP group compared to controls(P<0. 05),but in re-TURP group, difference in VEGF and AR expression as well as MVD were not found to be significantly different between the first and the second TURP(P>0.05). Conclusion Over expression of VEGF and AR as well as high MVD in prostatic tissue might play an important role in the pathological process of BPH after TURP.

Cells can adapt to environment and development by reconstructing their transcriptional networks to regulate diverse cellular processes without altering the underlying DNA sequences. These alterations, namely epigenetic changes, occur during cell division, differentiation and cell death. Numerous evidences demonstrate that epigenetic changes are governed by various types of determinants, including DNA methylation patterns, histone posttranslational modification signatures, histone variants, chromatin remodeling, and recently discovered chromosome conformation characteristics and non-coding RNAs (ncRNAs). Here, we highlight recent efforts on how the two latter epigenetic factors participate in the sophisticated transcriptional process and describe emerging techniques which permit us to uncover and gain insights into the fascinating genomic regulation.

Objective To evaluate the clinical efficacy of portal venous thrombolysis by way of TIPS.Methods The clinical data of 40 patients with portal venous system thrombosis treated by TIPS at our department from May 2012 to May 2018 were retrospectively analyzed.There were 34 cases of via catheterdirected thrombolysis(7 cases by catheter-directed thrombolysis alone and 27 cases by way of TIPS before catheter-directed thrombolysis),and 6 cases via pharmaco mechanical thrombectomy (AngioJet);the postoperative complications of the two methods were followed up.Results The portal vein was opened in all 40 patients,and there were no major complications during the operation.One patient in the catheter-directed thrombolysis group developed acute liver failure after surgery.In the mechanical thrombolysis group,1 patient was discharged after small intestinal necrosis resection and intestinal fistula reconstruction.After 6-24 months of postoperative follow-up,6 patients in the group of thrombolysis suffered from shunt canal stricture.Conclusions It is a safe and minimally invasive method to treat portal venous system thrombosis through TIPS.Mechanical thrombolysis is more direct and rapid than catheter thrombolysis.

To summarize the clinical characteristics and chest CT findings of coronavirus disease 2019(COVID-19)patients in Peking Union Medical College Hospital(PUMCH). A total of 13 patients with COVID-19 confirmed at PUMCH from January 20 to February 6,2020 were selected as the research subjects.Their epidemiological histories,clinical characteristics,laboratory tests,and chest CT findings were analyzed retrospectively.The location,distribution,density,and other accompanying signs of abnormal lung CT lesions were recorded,and the clinical types of these patients were assessed. The clinical type was "common type" in all these 13 patients aged(46.8±14.7)years(range:27-68 years).Ten patients had a travel history to Wuhan or direct contact with patients from Wuhan,2 cases had recent travel histories,and 1 case had a travel history to Beijing suburb.The white blood cell(WBC)count was normal or decreased in 92.3% of the patients and the lymphocyte count decreased in 15.4% of the patients.Twelve patients(92.3%)had a fever,among whom 11 patients were admitted due to fever and 2 patients(15.4%)had low fever.Eight patients(61.5%)had dry cough.The CT findings in these 13 patients were all abnormal.The lesions were mainly distributed along the bronchi and under the pleura.The lesions were relatively limited in 8 patients(affecting 1-3 lobes,predominantly in the right or left lower lobe),and diffuse multiple lesions of bilateral lungs were seen in 5 patients.The CT findings mainly included ground glass opacities(GGOs)(=10,76.9%),focal consolidation within GGOs(=7,53.8%),thickened vascular bundle passing through the lesions(=10,76.9%),bronchial wall thickening(=12,92.3%),air bronchogram(=10,76.9%),vacuole signs in the lesions(=7,53.8%),fine reticulation and interlobular septal thickening(=3,23.1%),reversed halo-sign(=2,15.4%),crazy-paving pattern(=2,15.4%),and pleural effusion(=2,15.4%). Most of our patients diagnosed with COVID-19 at PUMCH had a travel history to Wuhan or direct contact with patients from Wuhan.The first symptoms of COVID-19 mainly include fever and dry cough,along with normal or reduced counts of WBC and lymphocytes.CT may reveal that the lesions distribute along the bronchi and under the pleura;they are typically localized GGOs in the early stage but can become multiple GGOs and infiltrative consolidation in both lungs in the advanced stage.Scattered vacuole signs may be visible inside the lesions in some patients.
