Bronchiolitis is the most common lower respiratory tract disease in infants. There is no speciifc treatment for it and the treatment is mainly supportive. The management of bronchiolitis is the clinical hotspot recently. Continuous positive airway pressure (CPAP) has gained more attention in clinical application as it is a safe, effective, and noninvasive method and can effectively relieve symptoms of bronchiolitis and improve prognosis. This paper reviews the clinical application of CPAP in infants with severe bronchiolitis.

Objective To compare cardiovascular responses of intubations by Discopo and Macintosh laryngoscope in elderly patients with hypertension. Methods Sixty elderly hypertensive patients with ASAⅡ~Ⅲundergoing elective surgery were equally randomized into two groups. After induction of general anesthesia , orotracheal intubation was performed with Discopo or Macintosh. The Mean arterial pressure (MBP) and heart rate (HR), as while as Electrocardiogram (ECG) and Blood oxygen saturation (SpO2), were recorded before (baseline values) and at 1,3,5 minutes after intubation(post-induction values). The rate of one-time successive intubation,intubation time and complication were also recorded. Results Compared with the macintosh group, the rate of one-time successive intubation was higher and the intubation time was shorter in the Discopo group (P< 0.05, respectively),with no complications. Compared with T0,MBP and HR at T2 in the two groups and T3 in the Macintosh group increased significantly (P < 0.05). Compared with the Macintosh group,MBP and HR at T2,T3 of the Discopo group decreased significantly (P < 0.05). Conclusion Little effect of tracheal intubation with Discopo on cardiovascular response was observed in elderly hypertensive patients.

Hypertension is a global problem,affecting both developed and developing nations. The mor-bidity of hypertension in children and adolescents has increased year by year in recent years. Hypertension in children can cause target organ damages(mainly renal,cardiovascular,central neurological,or optic fundal). In clinical practice,we need to find simple and easy methods for early recognition of target organ damages,thus se-rious consequences in adult hypertension may be prevented.

This case report presents an extracted maxillary third molar,which have 3 separate roots with 5 canals,the canal configuration in mesiobuccal root are 3 separate orifices and canals,1 apical foramen.The clinician should be aware of this anatomical variation,avoid the missed canals.

To explore the relationship between self-concept and mental health. Methods:398 middle school students were tested by SCL-90 and Song-Hattie Self-concept Scale. Results: The correlation coefficients between the total score of SCL-90 and academic self-concept, non-academic self concept and total self concept were -0.22, -0.21 and -0.23 respectively. Conclusion: Self concept was significantly correlated with mental health in middle school students.

Functional gastrointestinal disorders is a common functional disease without organic pathologic changes, mainly including functional dyspepsia, irritable bowel syndrome and functional constipation.As the dissatisfaction, side effects and recurrence with drug treatment, transcutaneous electrical stimulation has taken an important role in the treatment of functional gastrointestinal disorders in recent years.This article reviewed the progress of transcutaneous electrical stimulation in treatment of functional dyspepsia, irritable bowel syndrome and functional constipation.

Objective To observe the bleeding risk of short-term intensive statin therapy after coronary artery bypass grafting. Methods A total of 240 patients treated with coronary artery bypass grafting were randomly divided into group A(experimental group)and group B(control group). All pa-tients were normalized to conventional treatment and they were given low molecular weight heparin for an-ticoagulant therapy during the perioperative period. Patients in group A were given 40 mg of atorvastatin before surgery,and 40 mg of atorvastatin every night for one month after the surgery. Patients in group B were given 10 mg of atorvastatin every night during the treatment. One month after the operation,platelet aggregation rate and bleeding events of patients were compared. Results There were significant differ-ences in maximum platelet aggregation rate[(14. 5 ± 3. 7)% vs(38. 1 ± 7. 4)% ,P < 0. 05],inhibition rate of platelet aggregation[(79. 5 ± 4. 3)% vs(50. 8 ± 10. 2)% ,P < 0. 05],and incidence of postopera-tive bleeding[27. 5% vs 12. 5% ,P < 0. 05]between group A and B,respectively. Conclusion Short-term intensive statin therapy can increase the bleeding risk after coronary artery bypass grafting.

In order to observe the febrffugal response and analysis on its mechanism of needling "Shang gen" point bilateral infraorbital nerves of rabbits were sected in the experiment. Fever models were made by leukocytic pyrogen. The experiment findings were as follows:1. It was found that when febrile response of leukocytic pyrogen in rabbits was significant, the cAMP content in CSF was strikingly increase (25.14?2.11pmol/L). During electric needling "Shang gen" point of febrile rabbits, however, fever response was markedly inhibited (△T was 0.27?0.07 at 60min); The cAMP content rise in CSF was markedly inhibited (11.22?0.13 pmol/ml).2. After sectioning bilateral infraorbital nerves of rabbits, the fever response of febrile rabbits was not depressed (△T was 0.71?0.06 at 60min) during electric needling "Shang gen" point. In the mean time, the cAMP content in CSF was significantly increased (28.53?1.12 pmol/ml).3. The authors inferred that the mechanism of febrffugal response of electric needling "Shang gen" point might be closely associated with producing nerves impulse (from the that point) which inhibited probablely the synthesis of cAMP through some modes.

OBJECTIVE:To promote safe,effective,economical and proper medication.METHODS:Prescriptions in the outpatient and emergency departments of our hospital in2003were randomly selected;the irrational prescriptions were ana?lyzed with regard to drug descriptions,pharmacological knowledge and literatures.RESULTS:The irrational one amounted to4.92%of the total selected prescriptions;antibiotics drug abuses amounted to84.12%of the irrational ones.The irrational drug use problems were mainly seen in administration scheme,repeated dosage,menstruum,administration,drug combina?tion,compatibility and combined toxicity.CONCLUSIONS:Clinical pharmacist plays an important role in promoting rational drug use by checking prescriptions.

OBJECTIVE: To introduce and analyze the present status of research on decomposed recipes of traditional Chinese medicine (TCM). METHODS: The relevant literature on the study of the decomposed recipes of TCM in the past five years was collected and analyzed. RESULTS AND CONCLUSION: Studies on the decomposed recipes of TCM have been made from the whole body level to the organ, cell and molecular research level. The pharmacological research in vitro is the main way and quantitative changes of the chemical ingredients have been measured before and after composition. It is very important to combine the modern science and technology in exploring the composing mechanisms of TCM remedies.
