Meticulous nursing care during nasal packing silicone ventilation tube could alleviate patients' discomfort obviously. It was emphasized to suck at exact time according to the patients' demands, adopt effective suction means to alleviate the damage of nasal mucosa,such as suction in the tube or in the bottom of the tube, take measures to promote the cleaning of secretion,which could improve the breath and sleep,as well as shorten the time of recovery.

Objective The purpose of our study is to evaluate high-resolution 3.0 T MRI in the identification of finding in patients with a clinical diagnosis of femoroacetabular impingement (FAI). Methods From June 2008 to May 2010, 54 consecutive patients with clinically diagnostic FAI received an high-resolution 3.0 T MR scan (Siemens AG, Germany), including 38 males and 16 females with an average age of 33.5 years (range, 18-50). All cases were assigned into 3 groups according to the morphology changes of the hip joint: Group Cum, Group Pincer, and Group Normal. The frequency of abnormal signs in 3 groups was calculated. Nonparametric tests by SPSS were used in data analysis. Results Forty-four patients (81.5%, 44/54) showed acetabular labrum disorders, 35 patients (64.8%, 35/54) showed femoral-acetabular cartilage lesions on MRI, 19 patients (35.2%, 19/54) showed arthroedema, 14 patients (25.9%, 14/54) showed femoralacetabular bone disorders, 4 patients (7.4%, 4/54) showed articular capsule and ligaments disorders. There was no statistically significant in the frequency of abnormal sign in MR1 between male and female. The frequency of acetabular labrum disorders, femoral-acetabular cartilage lesions and femoral-acetabular bone lesions in Group Cum was more than that of Group Pincer and Group Normal. The frequency of acetabular labrum disorders was the most disorders (Group Cum 88.5%, Group Pincer 77.8%, Group Normal 70.0%),next high-frequency was acetabular cartilage lesions. Conclusion 3.0 T MRI provides a useful assessment of patients in whom a FAI is clinically diagnosed. A high-resolution, nonarthrographic technique can provide preoperative information. Acetabular labrum disorders and femoral-acetabular cartilage lesions maybe characterized as an earlier period of FAI.

Forty five patients with acute cerebral infarction were randomized to two groups: in treatment group patients received local subhypothermia and conventional therapy, in control group patients received conventional therapy only. Clinical outcome was assessed by the National Institutes of Health Stroke Scale (NIHSS) on admission and at 7, 14 and 30 d after treatment. Serum neuron specific enolase (NSE), nitrogen monoxide ( NO ) , superoxide dismutase (SOD), interleukin-6 (IL-6 ) and intercellular adhesion molecule-1 (ICAM-1) were detected on admission and at 7,14 d after treatment The study showed that NIHSS scores of treatment group on 14, 30 d were lower than those of control group ( P ＜ 0. 05 ). Serum NSE, NO, IL-6 and ICAM-1 levels significantly decrease; while serum SOD levels increased (P ＜ 0. 05). In conclusion, local subhypothermia therapy can inhibit inflammatory reaction, reduce oxygen free radical formation and improve neurological function in patients with acute cerebral infarction.

Objective: This paper summarized the research status and progress of photodynamic therapy (PDT) and sonodynam-ic therapy (SDT), and we hope this can be a useful reference for clinics or research. Methods: In this review we expound their molecular mechanisms in detail and classify the photosensitizer and sonosensitizer, indicate their applications for the cancer treatment and summarize their new treating modes. PDT and SDT have huge potential for cancer treatment. Results: PDT and SDT have achieved a certain results, whereas there are still many problems, such as tissue oxygen content, new photosensitizer and sonosensitizer, drug dosage and mechanisms of SDT. Conclusions: PDT and SDT, which are new methods for treating cancer, have shown a good application prospect. But PDT has not been universal in clinics and SDT is still in the experiment stage.
