Objective To observe the clinical efficacy of different doses of warm needling in treating knee osteoarthritis (KOA). Method Sixty-seven KOA patients were randomized into group A of 16 cases, group B of 17 cases, group C of 18 cases, and group D of 16 cases. Group A, B, and C were intervened by warm needling, 1 moxa cone for group A, 2 cones for group B, and 3 cones for group C. Group D was intervened by intra-articular injection with Sodium hyaluronate. The Visual Analogue Scale (VAS) and Lysholm Knee Scoring Scale (LKSS) were evaluated before and after intervention.Result The VAS and LKSS scores were significantly changed in the four groups after intervention (P<0.01). After intervention, the VAS and LKSS scores in group B and C were significantly different from that in group A (P<0.05,P<0.01). After intervention, the VAS and LKSS scores in group B and C were significantly different from that in group D (P<0.05,P<0.01).Conclusion Warm needling is an effective method in treating KOA, and warm needling with 2 moxa cones can produce the best effect.

Objective To discuss the display format of cockpit displays of traffic information (CDTI) that would influence the performance of conflict detection at different conditions of temporal and spatial features of air traffic situation.Methods Fifty-four subjects viewed dynamic encounters between own aircraft and three intruder aircrafts with a simulated CDTI.Subjects were asked to estimate potential conflict between intruder and own aircraft.Effects on conflict detection performance were explored with CDTI display format as well as intruder's distance and time to closest point of approach (CPA).The experiment was designed to be three factors measured repeatedly.Results Intruder's distance and time to CPA influenced conflict detection performance when separated display format was adopted to show traffic information.When integrated display format was adopted,the two independent variables before mentioned didn't influence conflict detection performance,and subjects gained high level of conflict detection performance(P

Inhaled nitrous oxide (iNO) can alleviate pulmonary hypertension and enhance ventilation-perfusion matching to improve oxygenation in pediatric acute respiratory distress syndrome (PARDS).But duration of improvement was short.From the existing researches,iNO can't effectively improve outcome in PARDS.So iNO is not recommended for routine use in PARDS.However,iNO may be used in patients with documented pulmonary hypertension or severe right ventricular dysfunction.In addition,iNO can be a rescue intervention for severely PARDS to buy time and allow other therapies.

Objective To observe the clinical efficacy of acupuncture and miuci therapy combined with Qinggan Tongqiao Decoction for sudden sensor-neural hearing loss (SSHL) and the effects on level of plasma endothelin (ET) and serum nitrate oxide (NO). Methods Totally 110 patients with SSHL were randomly divided into treatment group and control group, with 55 patients in each group. The control group was given Qinggan Tongqiao Decoction combined with acupuncture routine treatment, and treatment group was given miuci therapy on the basis of the control group, two weeks as a course of two groups. Level changes of plasma ET and serum NO, and pure tone listening threshold changes before and after treatment were observed. Tinnitus and hearing efficacy was evaluated. Results The total effective rate for tinnitus efficacy was 94.54% (52/55) in the treatment group and 85.45% (47/55) in the control group, with statistical significance (u=2.038, P=0.040). The total effective rate for hearing efficacy was 96.46%(53/55) in the treatment group and 81.82% (45/55) in the control group, with statistical significance (u=2.913, P=0.040). Compared with before treatment, the level of plasma ET decreased and the level of serum NO increased after the treatment (P<0.05); After the treatment, the level of plasma ET in the treatment was lower than the control group, and the level of serum NO in the treatment group was higher than the control group (P<0.05). Pure tone threshold scores in the two groups on treatment 3, 7, 14 d were significantly improved (P<0.05), and pure tone threshold scores in the treatment group were significantly lower than the control group (P<0.05). Conclusion Acupuncture and miuci therapy combined with Qinggan Tongqiao Decoction can significantly reduce clinical symptoms and enhance the hearing level of SSHL patients. The mechanism mainly lies in regulating levels of plasma ET and serum NO, and improving the inner ear micro-circulation.

Methicillin-resistant Staphylococcus aureus (MRSA) infection can cause pneumonia,bacteremia,infective endocarditis and other diseases,seriously threat to the health of children.Pediatricians should discover the focus of infection.And the focus of infection should be removed or debrided in time.Vancomycin is an important drug for the treatment of MRSA infection,the use of Vancomycin need to ensure that the blood concentration is effective.Now,the advances in treatment of MRSA infection in children was mainly summarized.

AIM: To investigate the relationship between high density lipoprotein (HDL) subclasses and the binding activities of hepatic cell and extra-hepatic cell HDL receptor and intracellular protein kinase C (PKC). METHODS: Using purified pre-?_1 HDL and apoE-deficent HDL_3 to react with human smooth muscle cells (SMC) and HepG2 cells, then the activities of pre-?_1HDL and apoE-deficent HDL_3 binding to SMC and HepG2 cells, and the effects of this two HDL subclasses on PKC activities in SMC and HepG2 cells were observed . RESULTS: The results showed that the value of Kd of pre-?_1HDL binding to SMC HDL receptor was not only significantly lower than that of apoE-deficient HDL_3 (P

New guideline for the acute medical management of severe traumatic brain injury in infants,children,and adolescents was published in Pediatric Critical Care Medicine in 2012.This guideline made relevant recommendations and suggestions on intracranial pressure monitoring,threshold for treatment of intracranial hypertension,cerebral perfusion pressure thresholds,advanced neuromonitoring,neuroimaging and therapy for intracranial hypertension in pediatric patients with severe traumatic brain injury.This guideline was simply interpretated in order to improve the treatment of severe traumatic brain injury.

Intracranial hypertension is one of the most common pediatric acute and severe diseases.Intracranial pressure(ICP) monitoring can dynamically evaluate the changes of the patients with brain injury,calculate the cerebral perfusion pressure,guide the clinical treatment.ICP monitoring can not reflect the cerebral microvascular dysfunction and cell dysfunction,so it is necessary to carry out multimodality monitoring based on ICP monitoring.The information integration of ICP monitoring and multimodality monitoring is helpful to further understand the pathophysiological mechanism of brain injury,and it is also helpful for individualized treatment of patients.
