This paper reports the study and design of a visualization system of the ultrasonic rhinitis therapeutic apparatus with the function of endoscopic sinus. On Linux operating platform, we captured the video data of a video capture card that connected the endoscopic sinus using Video4Linux (V4L2) that was provided by the operating system. The video images were displayed by Qt. The visualization system solved the problem that the current ultrasonic rhinitis therapeutic apparatus had to rely on the large and expensive endoscopy equipment. And this simplified the doctors' operation, met the need of monitoring nasal cavity in the process of operating, greatly reduced the costs of treatment and would contribute to the promotion of the instrument. As a result, it has been tested that the nasal endoscopic image achieved by the system is clear and smooth, and fully meet the clinical needs of ultrasonic treatment of rhinitis.

OBJECTIVE:To investigate the protective effect of Tibetan medicine Compound Duoxuekang capsules on the acute lung injury in mice induced by lipopolysaccharide. METHODS:60 KM mice were randomly divided into blank group,model group,dexamethasone group (positive control,1 mg/kg) and Compound Duoxuekang high-dose,medium-dose,low-dose groups (3.6,1.8,0.9 g/kg,calculated by crude drug),10 in each group. Intragastrically administrated,mice in blank group and model group intragastrically administrated equal volume of normal saline,once a day. After 7 d of administration,except for blank group, mice in other groups intraperitoneally injected lipopolysaccharide to induce acute lung injury. After 6 h modeling,pathological changes in the lung tissue was observed,lung tissue water content was measured,superoxide dismutase(SOD),glutathione peroxi-dase(GSH-Px),malondialdehyde(MDA)levels in lung tissue and IL-6,TNF-α levels in serum were detected. RESULTS:Com-pared with blank group,mice in model group showed pathological changes in congestion and edema,inflammatory cell infiltra-tion,obvious widened alveolar septum and alveolar wall;water content in lung tissue and IL-6,TNF-αlevels in serum were signifi-cantly increased (P<0.01);SOD,GSH-Px levels in lung tissue were significantly decreased (P<0.01). Compared with model group,injury degree of lung tissue reduced to varying degrees in each treatment group,except for the water content,MDA level in lung tissue and TNF-α level in serum in Compound Duoxuekang capsules low-dose group;the above-mentioned indexes in other groups were significantly improved (P<0.05 or P<0.01). CONCLUSIONS:Compound Duoxuekang capsules can obviously re-duce mice's oxidative stress and inflammatory response,and has certain protective effect on acute lung injury in mice.

OBJECTIVE:To investigate the occurrence of ADR induced by over-the-counter(OTC)drug in order to guide the rational use of drugs. METHODS:45 cases of ADR induced by OTC drug were analyzed retrospectively in terms of patient's gen-eral information,allergic history,allergenic drugs,reason for drug use,route of administration,incubation period,days of hospi-talization,clinical manifestation,treatment,outcome,etc. RESULTS:Among 45 patients,there were 14 male and 31 female. The patients were mainly 20-30 year-old(31.1%). Three patients had previous history of allergy(6.7%). Most ADR were induced by oral drugs(82.2%). Reasons for drug use were mainly disease of respiratory system(23 cases,51.1%). The results of causality as-sessment were positive in 3 patients(6.7%),probable in 35(n=77.8%),and possible in 7 patients(15.6%). ADR were mainly induced by non-steroidal anti-inflammatory drugs (NSAIDs,57.8%),Chinese patent medicine (20.0%),drugs for external use (17.8%). The clinical manifestations mainly included exanthematous drug eruption (33.3%),erythama multiforme drug eruption (24.4%),urticarial drug eruption(13.3%). CONCLUSIONS:NSAIDs are the main allergenic drugs,and ADR induced by OTC traditional Chinese medicine can not be ignored. To improve medical knowledge and skills of the public and the scientific use of OTC drug are beneficial to improve the clinical treatment level.
