The role of DDX5 RNA helicases on cancer progression and development / 中国医师杂志

DDX5 helicase (DEAD box helicases 5), also known as P68, is an important member of an ATP dependent RNA helicase.Studies have shown that DDX5 is abnormally expressed in a variety of cancers, targeting a variety of tumor related signal pathways, regulating upstream and downstream factors to affect the occurrence, invasion and migration of tumor cells. This article describes the biological role of DDX5 in malignant tumors and provides prospects for targeted treatment of tumors.

Shorter Telomere Length Is Associated with Increased Breast Cancer Risk in a Chinese Han Population: A Case-Control Analysis / 한국유방암학회지

PURPOSE: The aim of this study was to investigate the association of telomere length with breast cancer risk. We simultaneously explored the association between telomerase reverse transcriptase gene polymorphisms and telomere length. METHODS: We used real-time quantitative polymerase chain reaction to measure relative telomere length (RTL) in genomic DNA extracted from peripheral blood from 183 breast cancer cases and 191 healthy controls. Genotyping was performed using the Sequenom MassARRAY platform. RESULTS: Our results show that breast cancer patients had significantly shorter RTLs than control subjects (p 40 years (OR, 2.41; 95% CI, 1.31–4.43; p=0.005), body mass index ≤24 kg/m2 (OR, 2.81; 95% CI, 1.55–5.10; p=0.001), and postmenopausal women (OR, 3.94; 95% CI, 1.63–9.51; p=0.002), respectively. In addition, individuals with the AA genotype of rs2853677 have longer telomeres than those of breast cancer patients with the AG genotype (p=0.011). CONCLUSION: Our results suggest that shorter RTL was associated with an increased risk of breast cancer. An association was found between the AA genotype of rs2853677 and longer RTLs in the case group. Functional studies are warranted to validate this association and further investigate our findings.

Study on the Molecular Mechanism of Stephania Terandra in the Therapy for Hypertension Based on Inte-grated Pharmacology Platform / 中国药师

Objective: To explore the potential genetic target of Stephania terandra in the therapy for hypertension based on inte-grated pharmacology platform to study the molecular mechanism of Chinese medicines in treating hypertension. Methods: Using the functional prediction modules of integrated pharmacology platform and the functional modules of network construction, the component-target network of Stephania terandra was calculated, and the target network of anti-hypertension was further calculated, and the target molecules related to hypertension were explored. Results: A total of 198 targets related to hypertension were obtained from the hyper-tension prevention. Among them, there were 59 potential action nodes and 20 known action nodes. The nodes with direct action were type-2 angiotensin Ⅱ receptor ( AGTR2), type-1 angiotensin Ⅱ receptor ( AGTR1), prostacyclin receptor ( PTGIR), solute carrier family 12 member 3 (SLC12A3) and endothelin-1 (EDN1). The GO enrichment and KEGG pathway enrichment of Stephania terandra chemical components showed a close correlation with hypertension, and the molecular mechanism of the target was clear. Conclusion:Through the integration of pharmacology platform, the targets of Stephania terandra-disease are deeply explored, and its potential mo-lecular mechanism as well as potential factors is studied.

Nasopharyngeal and oropharyngeal airway in obstructive sleep apnea syndrome, multi-plane operation application of perioperative / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To compare the mitigation role of nasopharyngeal and oropharyngeal airway in obstructive sleep apnea hypopnea syndrome (OSAHS) patients with upper airway obstruction after multiple plane operation. Observed parameters included life quality, the clinical value and reliability of nasopharyngeal and oropharyngeal airway.@*METHOD@#The nasopharyngeal airway group, 56 patients with PSG in patients diagnosed with severe OSAHS, after setting nasopharyngeal airway. Oropharyngeal airway group, 45 cases of OSAHS by PSG confirmed severe patients home after oropharyngeal airway, the same as the other treatment groups. Line postoperative ECG, oxygen saturation and hemodynamic monitoring. Two groups were compared in 24 h breathing difficulties, low oxygen saturation, hemodynamics, pharyngeal pain and discomfort of the situation.@*RESULT@#The multiplane after 24 h, the nasopharyngeal airway in patients hemodynamics HR (82.3 +/- 2.65) times/min, SBP(124.5 +/- 13.95) mmHg, DBP (76.2 +/- 8.1) mmHg, RPP(10282.0 +/- 1481.7), port pharyngeal airway in patients hemodynamics HR (93.4 +/- 2.89)times/min, SBP (135.1 +/- 16.5) mmHg, DBP (92.25 +/- 11.25) mmHg. There was significant difference between the two group (P 0.05); the lowest oxygen saturation nasopharyngeal airway group (95.2 +/- 1.6)%, oropharyngeal airway group (95.41 +/- 1.34)%, no significant difference between the two (P > 0.05). 24 h before and after surgery between patients with the same group in the hemodynamic parameters (HR,SBP,DBP,RPP), pharyngeal pain, lowest oxygen saturation difference was statistically significant areas (P < 0.05).@*CONCLUSION@#Ventilation tube in the nasopharynx and oropharynx in patients with severe OSAHS the same period of postoperative respiratory management plane could well lift the upper airway obstruction. However, nasopharyngeal ventilation tube has a better hemodynamic stability and tolerance, it can reduce patient suffering and increased health and safety from, it is a more safe, minimally invasive and effective method.

Clinical study of carbon dioxide laser tonsillectomy / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the therapeutic effect of carbon dioxide laser tonsillectomy.Method:In this prospective,randomized study, One hundred and two patients were divided into laser group or control group. Patients of laser group were cured with carbon dioxide laser tonsillectom,and the control group was cured with routine method. All operations are executed by one person. Observation index included operation time, hemorrhage in operation, ache after operation, inflammatory reaction of raw surface, repair time of raw surface, rehaemorrhagia and scar.Result:Laser group had advantages of less operation time, less hemorrhage, less ache and less inflammatory reaction of raw surface. Laser group have hemorrhage in operation (7.2±2.1)ml, while control group have hemorrhage in operation (92.0±35.0)ml. Laser group have pseudomembrane early but desquamate late.Conclusion:Carbon dioxide laser tonsillectomy is effective to relieve pain, inflammatory reaction and with less time ,it's an safe , efficient and mini-trauma operation.
