RESUMEN
Objective:To evaluate the visibility of intracranial deep medullary vein (DMV) by sensitivity weighted imaging (SWI), and explore its correlation with recent small subcortical infarct (RSSI).Methods:From March 2021 to May 2022, 277 patients with cerebral small vascular disease (CSVD) confirmed by cranial MRI in Department of Neurology, Third Hospital of Hebei Medical University, were consecutively enrolled. These patients were divided into RSSI group ( n=128) and non-RSSI group ( n=149) according to RSSI presence or not within one week of onset. According to the DMV scores, these patients were divided into mild-moderate DMV group (0-12 scores, n=199) and severe DMV group (13-18 scores, n=78). The clinical and imaging data of these groups were analyzed retrospectively and compared. Multivariate Logistic regression analysis was used to determine the correlation between DMV and RSSI, as well as the independent influencing factors for DMV grading. Results:The cerebral microbleed (CMB), periventricular white matter hyperintensity (WMH) scores, deep WMH scores, total WMH scores, total CSVD burden scores, and DMV scores in patients of the RSSI group were significantly higher than those in the non-RSSI group ( P<0.05); and patients in the RSSI group had significantly younger age and significantly lower high density lipoprotein cholesterol (HDL-C) level than those in the non-RSSI group ( P<0.05). Multivariate Logistic regression analysis showed that DMV score ( OR=1.142, 95%CI: 1.026-1.271, P=0.016) was an independent influencing factor for RSSI after adjusting for HDL-C and deep WMH scores. The severe DMV group had significantly older age, statistically higher percentages of patients having history of hypertension, CMB, lacuna and moderate to severe EPVS in basal ganglia, and significantly higher periventricular WMH scores, deep WMH scores, total WMH scores, and total CSVD burden scores as compared with the mild-moderate DMV group ( P<0.05). Multivariate Logistic regression analysis showed that age ( OR=1.101, 95%CI: 1.060-1.143, P<0.001) and total CSVD burden scores ( OR=3.589, 95%CI: 2.506-5.141, P<0.001) were independent influencing factors for DMV scores. Conclusion:DMV is involved in the mechanism of RSSI, and DMV visibility can be used as an indicator to diagnose RSSI and evaluate RSSI progression.
RESUMEN
Objective To conduct a bibliometric analysis of pediatric literature in recent 5 years in Pubmed database,and to explore the focus issues of pediatrics.Methods Bibliographies from research literature of pediatrics in PubMed database from 2012 through 2016 were retrieved.The publication years,journals,the prolific authors and frequency of Mesh major topics were counted.MeSH heading/subheading matrix were formed.SPSS 19.0 statistical software was applied for clustering analysis.Results A total of 9375 articles were included.There were 45 MeSH heading/subheadings,which were clustered into 4 categories.Conclusion The research focuses in pediatrics are as follows:the clinical competence training and education research;the related pediatric issues from the perspective of social medicine;medical error prevention and the related legislation;the situation of Chinese pediatricians and doctor-patient relationship.
RESUMEN
Objective To survey the status of knowledge and management capability on diabetic kidney disease (DKD) among general practitioners (GPs) in community health service centers (CHCs) of Shanghai.Methods A questionnaire survey was conducted among 152 GPs from 6 CHCs in 3 districts of Shanghai during May 2015 and March 2016.Results In the current survey,138 (90.8%) valid questionnaires of DKD knowledge and 152 (100.0%) valid questionnaires of DKD management capability were retrieved.The overall accuracy rate of DKD knowledge was 60.2% (1 246/2 070);the accurate rates of epidemiology,diagnosis,treatment,and community management knowledge were 62.7% (173/276),62.8% (520/828),60.6% (502/828)and 35.5% (49/138),respectively.There were significant differences in accuracy rates of treatment related questions among GPs with different years of working (P =0.032 2);but no significant differences were observed in accuracy rates of 4 aspects related questions among GPs with different education and professional title (P >0.05).Among 152 participants,113 (74.3%) responded to conduct DKD screening in clinic work;97(63.8%) chose renal function,86 (56.6%) chose urine routine and 86 (56.6%) chose urinary microalbumin for screening,respectively.The top three answers to "how to intervene patients with DKD" were blood glucose control(107,70.4%),medication of ACEI or ARB (77,50.7%),and high-quality low protein diet (68,44.7%).Conclusion The knowledge and management capability on DKD among GPs in CHCs are insufficient.The capability of diagnosis and treatment of DKD should be improved by joint efforts of GPs,trainers,and community health administrators.

Objective To investigate the effect of cold underwear on acute radioactive dermatitis in the cervical cancer patients undergoing radiotherapy.Methods Ninety-seven patients with stage Ⅱb and above Ⅱb cervical cancer receiving radiotherapy were divided into the control group (n =48) and the experiment group (n =49) according to the random digit table.In the control group,Orgotein was sprayed on the local skins and the experiment group was treated with wearing cold underwear for 20 minutes in addition to local spraying of Orgotein.The two groups were compared in terms of dermatitis on the early stage,middle stage and final stage.Result On the early stage there was no statistical significant difference between two groups on dermatitis (P>0.05),but the dermatitis in the experiment group was statistically less than that in the control group at the middle stage and final stage (P<0.01).Conclusions The cold underwear for the cervical cancer patients undergoing radiotherapy can effectively prevent dermatitis or reduce its severity.It is designed suitable for patients prom anatomical perspective and simple for application.
RESUMEN
Glioma is the most malignant tumor in CNS, the effect of present therapy is poor. A important discovery in tumor molecular biology is that the activation of oncogene and inactivation of tumor suppressor gene play an important role in the mechanism of tumorgenesis. The advances in the study of tumor suppressor genes in gliomas were reviewed.
RESUMEN
Objective To develop a new method to induce the gene transfection in high efficiency for eukaryotic cells in vitro. Methods Four kinds of p14ARF gene primarily deleted human carcinoma cell line including H460,A549,U251,and PC-3 were transfected with the human p14ARF expression vector (pCI-neo-p14ARF) by using the new nonliposomal transfection reagent Fugene 6. The efficiency of gene transfer was determined by screening the cells in G418. Results After 21 days' selection, G418-resistant clones were shown in all the transfected plate. PCR product of p14ARF gene was positive in all the G418-resistant clones. Cytotoxicity of Fugene 6 was detected. The cell proliferation activity was not affected when it was cultured in a high dose of Fugene 6. Conclusion These results demonstrate that Fugene 6 is a rapid, feasible, reproducible, and noncytotoxic gene transfection approach for eukaryotic expression vector in vitro.
