Objective To evaluate the safety and efficacy of fiberoptic bronchoscopy in the diagno-sis of 41 neonates with weaning failure.Methods A retrospective study on the results of fiberoptic broncho-scopy was performed in 41 neonates with weaning failure.Results A total of 41 neonates of throat abnor-malities were examined by fiberoptic bronchoscopy,including 38 cases with laryngomalacia,8 cases with seri-ous hyperemia and swelling of the vocal cords,2 cases with scar stenosis of subglottic,and one case in each of congenital laryngeal web,glottic insufficiency and congenital epiglottis cyst;trachea-bronchial abnormali-ties,including 31 cases with tracheomalacia,2 cases with tracheal stenosis,4 cases with partial bronchial ste-nosis,1 cases with bridging bronchus and 1 cases with tracheoesophageal fistula.Thirty-eight neonates under-went fiberoptic bronchoscopy to obtain bronchoalveolar lavage fluid and culture,bacterial culture positive in 15 cases(39.4%),of which 5 cases of Klebsiella pneumoniae,3 cases in each of Pseudomonas aeruginosa and Acinetobacter baumannii,2 cases of Staphylococcus aureus,1 case in each of Escherichia coli and Strep-tococcus mitis;fungal culture positive for 6 cases(15.7%),of which 3 cases of Aspergillus fumigatus,1 case in each of Candida glabrata,Candida albicans and Candida parapsilosis.The most common complications of fiberoptic bronchoscopy were hypoxia and heart rate transient decline(26 cases,63.4%),3 cases fever af-ter operation.Conclusion Fiberoptic bronchoscopy can not only find congenital tracheal deformity and tra-cheal mucosa lesions,but also complete the etiology from deep discharge.Fiberbronchoscopy is safe and relia-ble given adequate preparation and if it is performed by skilled personnel.

OBJECTIVE:To provide reference for rational use of polycystic ovary syndrome(PCOS)drugs. METHODS:The utilization of PCOS drugs in our hospital during Jan.-Dec. 2013 were analyzed in respects of consumption sum,DDDs,sorting and so on. The rationality of prescription was analyzed according to guidelines and drug package inserts and so on. RESULTS:There were 1 551 prescriptions,involving 76 kinds of drugs,and their total consumption sum was 181 072.90 yuan. Main types of drugs were hormone related drugs (accounting for 81.37% of prescription frequency,73.51% of consumption sum) and Chinese patent medicine (accounting for 15.41% of prescription frequency,19.43% of consumption sum). Top 5 hormone drugs in the list of DDDs were Ethinylestradiol and Cyproterone acetate tablets,Metformin hydrochloride enteric-coated tablets,Progesterone soft cap-sule,Dydrogesterone tablets and Progesterone soft capsules. Top 5 Chinese patent medicines in the list of DDDs were Kuntai cap-sule,Yougui capsule,Huanshao capsule,Jiawei xiaoyao capsule and Nvjin capsule. Single drug accounted for 72.08% in prescrip-tion. The proportion of irrational drug use was 1.69%. CONCLUSIONS:The application of drug in patients with PCOS is reason-able generally. Some prescriptions are unreasonable,mainly manifesting as incomplete clinical diagnosis,irrational usage and dos-age. Pharmacists should strengthen prescription verification and intervention.

Objective To compare the difference in pharmacokinetics characteristics of vancomycin in cerebrospinal fluid between administration by continuous infusion and interim infusion.Methods Twenty postoperative patients in the Department of Neurosurgery of Beijing Tiantan Hospital, Capital Medical University admitted into intensive care unit (ICU) to receive vancomycin for prophylaxis of intracranial infection were enrolled, and they were randomly distributed to a continuous intravenous infusion group and a interim intravenous infusion group, each group 10 cases. In continuous intravenous infusion group, the patients received a loading dose of vancomycin (15 mg/kg) by continuous intravenous pump infusion for 1 - 2 hours followed by 30 mg/kg vancomycin in a constant pump infusion rate for 24 hours; while in interim intravenous infusion group, the patients received 15 mg/kg vancomycin administered by intravenous pump infusion for 1 - 2 hours, once every 12 hours. The concentration of vancomycin in the cerebrospinal fluid at different time points was measured by two-dimensional liquid chromatography (2D-LC) method, the parameters of pharmacokinetics were calculated in the two groups, and the adverse reaction was observed.Results The comparison between the ratio of areas under the concentration-time curves (AUC) and minimum inhibitory concentration (MIC) of the continuous and interim groups showed no significant difference (19.7±14.0 vs. 16.1±6.4,P > 0.05). However, in the continuous intravenous infusion group, the drug concentration reached the peak value (0.96± 0.77)μg/mL at 12 hours, and later revealed a plateau concentration 0.91-0.93μg/mL for 12 hours; while in the intravenous infusion interim group, the drug concentration reached the peak value (0.92±0.47)μg/mL at 16 hours, in the later 2 hours declined to (0.84±0.45)μg/mL, and afterwards still had a tendency of persistent declination. In all the patients, no any adverse reaction related to the drug occurred.Conclusion Continuous intravenous infusion and interim intravenous infusion of vancomycin for the postoperative neurosurgical patients without intracranial infection have the similar efficacy of medication, but the former can achieve the peak concentration faster and later the fluctuation of drug concentration in cerebrospinal fluid is smaller than those in the latter.

BACKGROUND: Stellate ganglion block (SGB) has become a technique frequently used in the field of pain management for its wide indication spectrum. Its ameliorative effect on cephal-facial pain may be achieved by regulating the cerebrovascular diastolic and systolic functions and intensifying cerebral perfusion.OBJECTIVE: To observe the influence of SGB on the blood velocity of anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA) and vertebral artery with three-dimensional transcranial Doppler (TCD) in patients with caphal-facial diseases caused by is chemia or vascular spasm.DESIGN: A before-after control observation.SETTINGS: Department of Pain Management, Guizhou Provincial Orthopaedic Hospital; Department of Anesthesiology, the First Affiliated Hospital of Guangzhou Medical College; Department of Anesthesiology, the Second Affiliated Hospital of Sun Yat-sen University.PARTICIPANTS: Twenty patients of 18-50 years old were selected from the Department of Pain Management of Guizhou Provincial Orthopaedic Hospital from March 2004 to December 2005, including 6 cases of migraine,3 of cluster headache, 4 of muscle tension-type headache, 2 of nervous tinnitus and earache, and 5 of derangement of temporomandibular joint.METHODS: Unilateral SGB was performed by means of paratracheal anterior technique, with the following compound prescription: lidocaine (20 g/L)2.5 mL and dexamethasone 1 mg in normal saline with a total volume of 10 mL. SGB was performed once a day for 7 consecutive days as one course.MAIN OUTCOME MEASURES: The changes of blood velocity of ACA,MCA, PCA and vertebral artery were observed with three-dimensional TCD before SGB and at 30 minutes after SGB.RESULTS: All the 20 patients finished the treatment and entered the analysis of results. After treatment, the blood velocities of ACA, MCA and PCA of the blocked side were increased remarkably as compared with those before treatment [(76.20±3.83), (61.95±2.50) cm/s; (83.65±2.36),(77.55±2.69) em/s; (65.20±2.99), (58.70±2.2.35) cm/s; P ＜ 0.01], but that of vertebral artery had no significant change before and after treatment [(47.20±2.04), (45.55±2.23) cm/s, P ＞ 0.05]. CONCLUSION: The blood velocities of the blocked side are obviously increased after treatmeut, the increased blood velocities of ACA, MCA and PCA have important clinical significance for the blood supply of cerebral hemisphere, especially the anterior 2/3 part, but had little great influence on vertebral artery, indicating that SGB has great pertinence to the caphalfacial diseases caused by ischemia or vascular spasm, and can ameliorate the cerebral blood perfusion.

Objective To analyze the effects of health management of metabolic syndrome on the control of related risk factors. Methods A total of 430 patients diagnosed with metabolic syndrome in 2008completed questionnaire and before randomly assigned to the health management group ( n = 207 ) and the control group (n=223). One year later, all the participants were investigated for the risk factors of food intake, cigarette smoking, alcohol consumption, staying-up and emotion, and the changes of body mass index ( BMI), blood pressure ( BP), triglyceride (TG), high-density lipoprotein cholesterol (HDL) and fasting blood glucose (FBG). Student's t test and x2 test were used for data analysis. Results For the health management group, the incidence of high-salt, high-fat and high-sugar intake, overtake of food, lack of physical exercises,staying-up and alcohol drinking was significantly decreased at 1 year (P ＜ 0. 05 ), when compared with baseline and the control group ( both P ＜ 0. 05 ). For the health management group, BMI,systolic blood pressure (SBP),TG and FBG was improved at 1 year (P＜0. 05). In comparison with the control group, BMI, SBP, diastolic blood pressure (DBP),TG and FBG of the management group were significantly improved (P ＜ 0. 05 ). Conclusions Patients with metabolic syndrome may have better treatment compliance after receiving systematized and individualized health management.

Objective To explore the value of somatosensory cortex evoked potential(CSEP)monitoring in objective evaluation of spinal cord function and integrity as well as prognostication of neural function after surgery.Methods CSEP monitoring was performed before the operation,during surgical procedure and after the operation in 56 spinal cord surgery patients to observe and analyze latency and amplitude of cortical potential.The significant changes were amplitude reduction≥150%or latency prolongation≥10%.Results There were 71.43%(40/56)true negative finding,both latency and amplitude without abnormal changes during the operation and without new neural functional deficit after operation.There was 0.18%(1/56)false negative finding,latency and amplitude without abnormal changes during surgical procedure,but with new neural functional deficit after operation.There were 26.79%(15/56)true positive findings,where latency transient prolongation<10%and amplitude reduction<50%during surgical procedure were observed.After suspending procedure or changing direction during surgical procedure,the waveform restored or improved.Conclusion CSEP monitoring during surgical procedure could reflect the sensitiveness to distracting,ischemia and injury of spinal cord.A timely intervention might improve the CSEP.CSEP could reflect the function and integrity of spinal cord.CSEP possess an important value in preventing spinal cord injury and evaluating the prognosis of neural function.

Objective To investigate health status of primary or middle school teachers. Methods A total of 4482 physical examination results of the teachers from Qiaokou District of Wuhan in 2008 were compared with 5526 data obtained in 2006. The rate of healthy to unhealthy participants was evaluated. The overall and age-specific disease incidence, including overweight, hypertension, hyperlipidmia, hyperglycemia,liver dysfunction, abnormal EGG, concrement, adiposis hepatica, and HBV infection, was recorded. X2 test was used for statistical analysis. Results Abnormal examination results were more common in 2008 when compared with those in 2006( X2 = 28. 35, P ＜ 0. 05 ). The incidence of hypertension was descended ( X2 =4. 51 ,P ＜ 0. 05 ), although the rates of hyperlipidimia, hyperglycemia, liver dysfunction, abnormal ECG,concrement, and adiposis hepatica were increased in 2008 ( P ＜ 0. 05 ). The incidence of hyperlipidimia, liver dysfunction, abnormal ECG, and adiposis hepatica increased in all age groups ( P ＜ 0. 05 ). The incidence of hyperglycemia and concrement increased in those ＞ 35 years old ( P ＜ 0. 05 ). Conclusion Except for hypertension and HBV infection, the incidence of common diseases has been increased in the young and middle-aged teachers during the last 2 years. Thus the health management for the primary or middle school teacher should be improved in the future.

Objective To assess the value of fiberobronchoscopy in the diagnosis of endobronchial tuberculosis. Methods A total of 67 children suspected of endobronchial tuberculosis in our ward from March 2010 to December 2012 had been tested by chest CT and ifberobronchoscopy, mycobacteria culture, liquid-based interlayer vessel technique and FQ-PCR from bronchoalveolar lavage fluid and biopsy. Results 50 patients were clinically diagnosed as endobronchial tuberculosis. The positive rate of FQ-PCR (60%) and liquid-based interlayer vessel technique (42%) are higher than that of mycobacteria culture (20%), which showed no signiifcant difference with biopsy. The positive rate of the combined detection (FQ-PCR and liquid-based interlayer vessel technique) is significantly higher than that of mycobacteria culture and biopsy. Conclusions Fiberobronchoscopy is effective for the diagnosis of endobronchial tuberculosis.

OBJECTIVE: To explore the clinical symptoms and signs situation of chronic rhinosinusitis, for future treatment provides the basis. METHOD: The clinical data of 337 patients with chronic sinusitis were analyzed, using SPSS 18.0 software and conducted Person chi-square test and Kruskal-Wallis test to analysis. RESULTS: VAS total score of chronic nasal sinusitis patients is 15.9 +/- 5.7. The three top of severe symptoms were: stuffy nose 56 cases (16.6%), nasal secretions or postnasal drip 23 cases (6.8%) and dizziness or headache 11 cases (3.3%), there are statistically significant differences (chi2 = 430.923, P < 0.01). Lund-Kennedy score found side with mucosa edema and secretion serious degree higher than nasal polyp, there are statistically significant difference (chi2 = 128.684, P < 0.01). Lund-Mackay score showed that the three top parts of all shadow were: maxillary sinus 314 side (46.6%), OMC 135 side (20.0%) and the former screen 112 side (16.6%), there are statistically significant differences between groups (chi2 = 803.274, P < 0.01). The pearson correlation coefficient r between VAS score and Lund-Kennedy score is 0.516, there are correlation (P < 0.05). VAS score and Lund-Mackay (r = 0.213), there are not correlation (P > 0.05). CONCLUSION Comprehensive treatment should be proceeded according to different symptom severity and sinus lesions parts with patients, grasped the surgery procedures strictly, so as to improve the cure rate.
