ABSTRACT

With the continuous research and elucidation of the role and species of long non-coding RNAs (lncRNAs),the relationship between lncRNAs and cancer resistance has been paid more and more attention by researchers.Studies find that lncRNAs are involved in tumor drug resistance by altering DNA repair and cell cycle,drug delivery system,drug metabolism,cell apoptosis and epithelial interstitial transformation.lncRNAs are expected to be a new biological marker,which provids a new way to diagnose,treat and evaluate the prognosis of cancer.

ABSTRACT

To investigate the incidence of malignant tumors in oral and maxillofacial region and the pathological features of various tumors, a total of 3 382 cases of malignant tumors in oral and maxillofacial region admitted to Jilin University from Januarary 2000 to December 2017. The characteristics of age, sex, location and pathological types of all kinds of tumors were analyzed. The median onset age is 57 years old, 51 to 70 years old is a high-risk age group, the ratio of male to female was 1.9∶1. The primary tumor location is tongue, gingiva and floor of mouth. Epithelial, lymphatic hematopoietic system, bone and soft tissue were the three major sources of tumor tissue, and squamous cell carcinoma was the most common pathological type (65.1%), followed by mucoepidermoid carcinoma and adenoid cystic carcinoma. In summary, oral and maxillofacial malignancies have a high incidence in elderly men, and tongue is the most common site of disease. Epithelial-origin and squamous cell carcinomas are the first of their origins and pathological types, respectively.

ABSTRACT

<p><b>BACKGROUND</b>Elderly multiple organ dysfunction syndrome (MODS) patients receiving invasive mechanical ventilation have poor prognosis in intensive care units (ICUs). We studied the usefulness of four commonly used severity scores and extrapulmonary factors that affected weaning to predict outcome of such patients.</p><p><b>METHODS</b>Clinical data of 197 patients on admission to ICUs (from January 2009 to June 2012) were used retrospectively. The Acute Physiology and Chronic Health Evaluation (APACHE) II, APACHE III, Sample Acute Physiological Score (SAPS) II and MODS scores were calculated. All the patients were grouped into survivors and nonsurvivors according to the prognosis. Patients, who weaned from ventilator (n = 154), were subdivided into a successful weaning group and a failed weaning group. The receiver operating characteristic (ROC) curves and Logistic regression was used for prognostic and weaning assessment.</p><p><b>RESULTS</b>Based on the outcomes, the areas under the ROC of APACHE II, APACHE III, SAPS II, and MODS were 0.837, 0.833, 0.824, and 0.837, respectively. The Logistic regression analysis revealed that the odds ratio (OR) of underlying lung diseases, serum albumin and creatinine, and the number of organ failures was 2.374, 0.920, 1.003, and 1.547. APACHE II scores on admission performed excellent (ROC: 0.921) on the weaning assessments.</p><p><b>CONCLUSIONS</b>APACHE II and MODS systems were marginally better for evaluating the prognosis of elderly MODS patients who received invasive mechanical ventilation. Underlying lung diseases, serum albumin, serum creatinine and the number of organ failures were independent prognostic factors. Using the APACHE II scores on admission before weaning may increase the likelihood of successful weaning. (ClinicalTrial.gov identifier NCT01802983).</p>

ABSTRACT

Objective The method transcranial Doppler (TCD)and end-tidal carbon dioxide partial pressure (ETCO2 ) was used to investigate the cerebrovascular reserve capacity in patients with intracranial artery stenosis.Including the cerebral vasodilator reserve,contracted reserve and the overall reserve.Methods The 72 cases were enrolled in this study,include of 42 patients with one or two sides middle cerebral artery (MCA) stenosis,or other intracranial artery stenosis and 30 normal persons. All the patients were routinely examined with TCD,and the TCD QL software was used to evaluate the cerebrovascular reserve. Hypercapnia was induced by inhaling the CO2 who breathed himself,and hypocapnia was induced by voluntary hyperventilation. The changes of velocities were recorded in both side of MCA,and the ETCO2 was recorded by the external measuring device. Results ( 1 ) The cerebral vasodilator reserve of one side of MCA stenosis group ( ( 3.65% ± 2. 62% )/mm Hg),the heavier side of multi-vessel stenosis group ( ( 1.99% ± 2. 78% )/mm Hg ),and normal control group ( left ( 3.54% ± 1.66% )/ mm Hg; right (3. 81% ± 1.63% )/mm Hg) had significant difference( F = 3. 755 ,P < 0. 05 ). The heavier side of multivessel stenosis group' s cerebral vasodilator reserve were significantly lower than normal control group ( t =- 2. 546,P < 0. 05 ). (2) The overall reserve of one side of MCA stenosis group ( ( 3.22% ± 1. 27% )/mm Hg),the heavier side of multi-vessel stenosis group( (2. 30% ± 1.14% )/mm Hg),and normal control group(left (3. 19% ±0. 81% )/mm Hg;right (3. 23% ±0. 70% )/mm Hg)had significant difference(F=5. 894,P <0. 01 ). The heavier side of multi-vessel stenosis group' s overall reserve were significantly lower than normal control group( t = - 3. 357,P < 0. 01 ) and they were also significantly lower than one side of MCA stenosis group (t = 2.471,P < 0. 05 ). (3) The extent of vascular disease correlated inveresely to the cerebral vasodilator reserve( r = - 0. 322,P < 0. 05 ) and the overall reserve( r = - 0. 364,P < 0. 05 ) in the heavier side of patients who have vascular disease.Conclusions ( 1 ) TCD with ETCO2 is a simple,economic and effective method for assessing CVR. (2)The capacity of cerebrovascular reserve was reduced in patients with intracranial artery stenosis.
