Objective To assess the effectiveness of balloon dilation and airway stenting performed under fluoroscopic guidance for the treatment of benign and malignant tracheal stenosis. Methods Under fluoroscopic guidance,balloon dilation and airway stenting were performed in 45 patients with tracheobronchial stricture. Of the 45 patients, malignant tracheal stenosis was seen in 37, including mediastinal nodal metastases (n = 14), esophageal carcinoma (n=13), lung carcinoma (n = 4), adenocarcinoma of bronchus (n = 3), lymphoma (n = 2) and laryngocarcinoma (n = 1), and benign tracheal stenosis was seen in 8, including endobronchial tuberculosis (n = 6), retrosternal thyroid adenoma (n = 1) and endotracheal intubation (n = 1). Airway stenting with serf-expandable metal stent was employed in 38 patients and balloon dilation in 7 patients. All the procedures were performed under fluoroscopic guidance. Results A total of 53 self-expandable metal stents was implanted in 38 patients. The clinical symptoms were immediately relived after the procedure in all patients except for one patient who died from choking of sputum. No stent migration was observed. Restenosis developed in 4 patients, which was successfully treated with repeated stenting and balloon dilation. Nineteen times of balloon dilation procedure were accomplished in 7 patients. Marked remission of clinical symptoms was seen in most cases. During a follow-up period (ranged from 0 to 124 months with a mean of 24.5 months) 31 patients died. Conclusion For both benign and malignant tracheal stenosis, balloon dilation with airway stenting performed under fluoroscopic guidance is a safe and efficient therapy with instant curative effect in relieving clinical symptoms.

A pregnant lady in her third trimester presented with a rapidly growing right-sided nasal mass associated with epistaxis and nasal obstruction for six months. Examination showed a non tender, protruding mass completely occluding her right nostril. Wide surgical excision was done under anaesthesia. Histopathology revealed capillary haemangioma. In a gravid patient with a rapidly growing intranasal lesion, capillary haemangioma should be considered as a differential diagnosis.

Objective:To investigate the serum level of miR-224 in hepatocellular carcinoma (HCC) patients and its clinical diag-nostic significance. Methods:The serum level of miR-224 was detected by real-time quantitative PCR. This study included 42 cases of patients with HCC, 36 patients with liver cirrhosis (LC), 55 patients with chronic hepatitis B (CHB), and 40 healthy persons (NC). The relative expressions of miR-224 were calculated. The receiver operating characteristic (ROC) curves were analyzed to determine the sensitivity and specificity of miR-224 expression levels in HCC diagnosis. Results:Result shows that the relative miR-224 expression was higher in the serum of HCC patients than that in the CHB, LC, and NC groups. The difference was statistically significant (P<0.05 or P<0.01). The relative miR-224 expression in the serum of HCC patients and alpha fetoprotein (AFP) were positively correlated (P<0.05). By comparison, the tumor size, TNM stage, tumor differentiation, and lymph node metastasis were not correlated with mirR-224 expression (P>0.05). ROC analysis shows that the best critical value of the relative expression levels of miR-224 was 3.47, with sensi-tivity of 82.2%, specificity of 92.8%, and area under the curve of 0.935. Conclusion:The serum level of miR-224 in HCC patients has high specificity, and miR-224 has great potential to become a new serological marker for the diagnosis of HCC.

OBJECTIVE:To observe the efficiency and safety of budesonide,azithromycin combined with terbutaline in the treatment of infantile acute bronchitis. METHODS:150 children with acute bronchitis were randomly divided into control group(75 cases) and observation group(75 cases). All children were given electrolyte supplement,antiasthmatic,antispasmodic and other conventional treatment;based on it,control group was treated with 10 mg/kg Azithromycin injection,adding into 250 ml 5% Glu-cose injection,by intravenous infusion with time of more than 60 min,once everyday+2 mg Terbutaline sulfate spray solution,add-ing into 2 ml 0.9%sodium chloride injection,aerosal inhalation,twice a day,15 min for every times. Observation group was addi-tionally given 1.0 mg Budesonide aerosol;3 times a day,10 min for every times. The treatment course for both groups was 10 d. FEV1,MEF50,PEF before and after treatment,total effective rate and disappearance time of clinical symptoms,hospitalization time and incidence of adverse reactions were recorded. RESULTS:The total effective rate in observation group were significantly higher than control group,disappearance time of clinical symptoms and hospitalization time were significantly shorter than control group,the differences were statistically significant(P<0.05). After treatment,FEV1,MEF50 and PEF in 2 groups were significant-ly higher than before,and observation group was higher than control group,the differences were statistically significant(P<0.05);there was no significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Based on conventional treament,budesonide,azithromycin combined with terbutaline is effective in the treatment of infantile acute bronchi-tis,and it can significantly improve lung function,with good safety.

To investigate the expressions and changes of serum soluble intercellular adhesion molecule-1 (sICAM-1) in lung cancer patients before and after operation and the roles of sICAM-1 in differential diagnosis, metastatic potential, and prognosis. Methods From 2002 to 2003, a total of 17 samples of lung carcinoma tissues and sera were studied. The other 11 non-cancer patients were employed as the controls. Cell surface sICAM-1 levels were analyzed by immunohistochemistry method and ELISA. Results The serum sICAM-1 concentration in the cancer patients was (432.0?124.4) ng/ml. In the controls, however, the serum concentration of sICAM-1 was (262.3?77.7) ng/ml. In patients with lung cancer, the serum concentration of sICAM-1 was significantly higher than that of the controls (P0.05). Conclusion The serum sICAM-1 concentrations in lung cancer patients may play an important role in staging and may also serve as a useful indicator of advanced disease.

Objective To investigate incision pathogenic bacteria after spinal surgery, and observe clinical effects of therapeutic methods. Methods A total of 30 cases of early surgical incision infection (7 cases of superficial infection and 23 cases of deep infection) after spinal surgery were retrospectively analyzed. The basic data including clinical manifes-tations, diagnosis, treatment, etiology and follow-up results were analyzed. Results It was found that the mean infection time after operation was 2-15 days in 30 patients. Thirty-three strains were isolated including 18 gram-positive cocci (54.5%, and Staphylococcus aureus account for 13, 39.4%), 15 gram-negative bacteria (45.5%, and Coli communior account for 6, 18.2%). The drug susceptibility test showed that gram-positive cocci were highly sensitive to vancomycin, rifampin, tei-coplanin and cotrimoxazole. No vancomycin-resistant Staphylococcus aureus were found. Gram negative bacteria were high-ly sensitive to imipenem (100%). Seven cases of superficial infection were cured after dressing. Twenty-three cases of deep incision wound infection were no recurrence of infection after treatment by deep wound debridement, and postoperative cathe-terization. Conclusion The early wound infection after spinal surgery is usually due to Staphylococcus aureus. It is good to perform wound debridement, continuous perfusion drainage, and treatment with vancomycin for deep wound infection.
