OBJECTIVE To evaluate the therapeutic effect of intranasal endoscopic surgery on inverted papilloma of the nasal cavity and paranasal sinuses in stage Ⅰ-Ⅲ. METHODS According to the staging system developed by John H.Krouse,30 cases with inverted papilloma in the nasal cavity and paranasal sinuses in stage Ⅰ-Ⅲ were analyzed retrospectively. All patients were treated by intronasal endscopic surgery and were followed up for 24 months. RESULTS The inverted papilloma was removed completely and no serious complications occurred. One case recurred at 10 month after surgery and pathologically proved to be cancerated. Another 2 case recurred at 6 and 7 month after surgery respectively. Recurred tumors were removed again, no recurrences occurred in the following up period. The recurrence rate was 10 % and canceration rate was 3.3 %. CONCLUSION Endoscopic surgery is an effective method in management of the inverting papilloma in nasal cavity and paranasal sinuses in stage Ⅰ-Ⅲ.

Objective To analyze the specimen types,ward distribution and risk factors for infections caused by extended-spectrum β-lactamase(ESBLs)-producing-Escherichia coli(ECO) in recent two years,so as to provide bacteriological basis for both hospital infection control and clinical anti-infection treatment.Methods Non-repetitive 443 ECO strains isolated from the hospitalized patients in the Third People′s Hospital of Shenzhen were collcted,and the phoenix100 system was employed for bacterial identification and antimicrobial susceptibility tests.ESBLs-ECO was further confirmed by the double-disk synergy test,and the risk factors caused ESBLs-ECO were statistically analyzed.Results A total of 115 strains of ESBLs-ECO were identified among the 443 strains of ECO,which accounted for 26.0%.The ESBLs-ECO strains were mainly isolated from the sputum,urine,and blood specimens.Among the isolated ESBLs-ECO strains,20.9% were isolated from the department of Tuberculosis,13.9% from the department of pediatric,12.2% from the department of live disease,and 8.7% from the department of infection.The male sex,surgery and use of the third generation cephalosporins were independent risk factors of ESBLs-ECO infection.Conclusion The isolation rate of ESBLs-ECO in this hospital is high.It is necessary for the hospital to strengthen the control of nosocomial infections according to the risk factors.More attention should be payed on male patients,the standardization of surgical operation and disinfection,and the restriction of using the third generation cephalosporins,so as to reduce the incidene of ESBLs-ECO infections.

Objective:To observe any effects of electroacupuncture (EA) at acupoints CV23 and GV16 in activating c-Fos genes in the brain regions related to swallowing.Methods:Twenty C57 mice were randomly divided into a blank group, an EA at CV23 group, an EA at GV16 group and an EA at CV23+ GV16 group, each of 5. All except the mice in the blank group were given EA at the relevant acupoints CV23 or GV16 or both, respectively, for 15min. Samples were collected from all of the groups 50min after the EA treatment, and immunofluorescence staining was used to quantify the expression of the c-Fos gene in the brain regions controlling swallowing.Results:In the nucleus tractus solitarii the average number of c-Fos positive cells of the CV23 group was (445.1±43.14)/mm 2, significantly higher than the (297.47±25.54)/mm 2 of the GV16 group. No significant differences were observed in the average number of c-Fos positive cells in parabrachial nucleus. In the primary motor cortex the average number of c-Fos positive cells in the GV16 group was significantly higher than in the other two groups. In the primary sensory cortex the CV23+ GV16 group had a significantly higher average number. Conclusions:EA at the CV23 most strongly activates the c-Fos gene in the nucleus tractus solitarii. For c-Fos activation in the primary motor cortex GV16 is the most effective point. For c-Fos activation in the primary sensory cortex, EA at CV23 and GV16 together is recommended. These results may guide the selection of acupoints in treating dysphagia.

Objective:To seek any correlation between cortical activity and the swallowing of dysphagia patients with infratentorial stroke, and to observe any effect of three-needle acupuncture of the tongue on such activity.Methods:Thirty infratentorial stroke survivors with dysphagia were randomly divided into a tongue three-needle group and a sham acupuncture group, each of 15. Functional near-infrared spectroscopy was used to monitor changes in the concentration of oxygenated hemoglobin (ΔHbO 2) at rest, during acupuncture (or sham acupuncture), during real or sham electro-acupuncture, and at rest after the acupuncture or sham acupuncture treatment. The Modified Rankin Scale, a Penetration-Aspiration Scale (PAS), and the Functional Oral Intake Scale were employed to assess overall functional disability and the swallowing of both groups. Results:At rest the average ΔHbO 2 concentrations recorded in the left primary motor cortex, the left dorsolateral prefrontal cortex and the left premotor cortex in both groups were positively correlated with the PAS scores. During the acupuncture ΔHbO 2 concentration in the right inferior frontal gyrus and the left middle temporal gyrus increased significantly in the tongue three-needle group. It decreased significantly in the left somatosensory cortex and the left primary motor cortex. Conclusion:Three-needle acupuncture of the tongue induces changes in cortical activity in infratentorial stroke survivors with dysphagia, suggesting a potential technique for improving disordered swallowing.
