OBJECTIVEWe aim to explore the central auditory nervous system (CANS) functioning in children with nonsyndromic cleft palates by analyzing the auditory evoked potentials and event-related potentials (ERP).
METHODSA total of 34 children with nonsyndromic cleft palates were recruited as subjects, and 27 normally developed children were selected as the normal controls. Auditory brainstem response (ABR), middle latency response (MLR), and mismatch negativity (MMN) of ERP were selected as indices to observe the function of CANS in children in both groups.
RESULTSAstatistically significant difference between the groups was obtainedin the MMN recording (F = 227.69, P < 0.01), whereas no significant group differences were obtained in the ABR and MLR results (P > 0.05). Children with nonsyndromic cleft palates showed diminished MMN responses compared with the normal controls, whereas ABR and MLR were within the normal range.
CONCLUSIONChildren with nonsyndromic cleft palates are at risk of central auditory discrimination dysfunction. The significant abnormal event-related potentials recorded in children with cleft palates suggest that the dysfunction of CANS maybe located at the cortical level and normal function of CANS was located at the brain stem and sub-cortical level.

Objective To research the method and effect about the bronchoscopic lung volume reduction by ?-cyanoac- rylate in the therapy of chronic obstructive pulmonary disease (COPD).Methods The 14 patients had been examined bosoms by CT before the operation and determined the type of emphysema and the distributing of pneumatocele,had blood gas analyzed and pulmonary function checked.The operation was carried through trachea cannula and intravenous anesthe- sia.When the bronchoscope came to the goal bronchia,we infused the meglumine diatrizoate through the biopsy orifice and approved the location of pneumatocele forward。Then,we infused erythromycin and ?-cyanoacrylate in turn through the biopsy orifice by silica del tube.Results The 3 pneumothorax patients had been removed the drainage tube in 3 days af- ter the operation.8 cases had been counterchecked sternite in one week and the pneumatocele was just like before,among which,1 case developed exudation.1 case had shown pleural thickening in the right-up lung counterchecked sternite 9 months later.1 case been checked the pulmonary function,the FEV_1 enhanced from 24.7% pred before operation to 32. 9% pred after operation one week.3 cases felt polypnea improved greatly and 7 cases felt polypnea improved a little.Con- clusion The bronchoscopic lung volume reduction by ?-cyanoacrylate is a safe,effective and economical method in the therapy of COPD.

A bacterium which can effectively degrade LAS (Linear Sodium Alkylbenzenesulfonate) was isolated from washing powder manufacturing effluent and was preliminarily identified as Corynebacterium jeikeium GZ6. The bacterium can degrade LAS up to till 700 mg/L, and the optimum pH, temperature and concentration of LAS are 7.0, 30℃ and 400 mg/L, respectively. The biodegradation rate can reach 98.7% after 24 hours'cultivation in the suitable conditions. Experiments also showed that some heavy metal ions such as Hg2+ , Co2+ , Cd2+ can differently inhibit the degradation of LAS.

ObjectiveTo study the clinical features, arterial involvement, therapeutic strategies and outcomes of Takayasu arteritis (TA). MethodsThe clinical symptoms, arterial images, inflammatory parameters and follow-up information of 173 patients with TA were retrospectively studied. Comparisons between groups were performed by t-test. ResultsThere were 136 female and 37 male patients in this study. The mean age at onset was(26±11 ) years. Hypertension, pulse deficit or asymmetrical pulse, and fever were present in 46.6%, 41.1%, 28.7% of patients, respectively. The distribution of arterial involvement were 64.7%in aorta, 9.8% in pulmonary artery, 19.1% in innominate artery, 65.9% in common carotid arteries, 65.3%in the subclavian artery, 36.2% in the renal artery, 12.1% in the vertebral artery, and 5.8% in coeliac axis.Elevated erythrocyte sedimentation rate(ESR) was found in 61.0% patients. Active tuberculosis or history of tuberculosis was implicated in 45 patients(26.0%). Ten patients(5.8%) were hepatitis B virus carriers.Among 105 followed-up patients, 98 patients(94.2%) achieved persistent remission, 17 patients relapsed when corticosteroids were tapered. ConclusionCorticosteroids combined with or steroid alone, supplemented with endovascular intervention procedures or surgical bypass procedures when necessary, can effectively control the clinical symptoms and inflammatory parameters and improve the quality of life of patients.

To analyze and compare the protective effects of active components in different ethyl acetate extracts (EAEEPs) from Eclipta prostrate, in order to study the comparison of materials bases protecting normal human bronchial epithelial (NHBE) cells. The MTT assay was taken to compare the protective effect of different EAEEPs on cigarette smoke extracts (CSE) -induced NHBE cells. The ultra-performance liquid chromatography (UPLC) was applied to analyze the content of phenolic acid, coumaric grass ether and flavonoid in EAEEPs. According to the results, all of the eight EAEEPs (0-200 mg x L(-1)) showed certain protective effect on NHBE cells, with statistical difference. Specifically, the total mass of EAEEP VII (89.15 mg x L(-1)) and EAEEP VIII (57.44 mg x L(-1)), which showed the strongest activity, was not the highest, while EAEEP III (132.25 mg x L(-1)) displayed the highest total mass. In the combination with the "component structure" theory, the analysis showed a significant difference in the mass structure among phenolic acid, coumaric grass ether and flavonoid in EAEEP VIII and EAEEP VIII, which were 1.0: 1. 0: 0.5 and 1.0: 1.9: 0.8, respectively. The results suggested a specific optimal "component structure" relationship may exist in EAEEP, which could provide reference for the material base study and quality control.

Conventional randomized controlled trial is considered as the gold standard of clinical trials in evalua ting pharmacologic effectiveness. Whereas, it still has some faults in the non-pharmacy interventions, such as surgery, acupuncture, massage, etc. Expertise-based randomized controlled trial makes up for some deficiencies of conventional randomized controlled trial, which has made better developments in the field of surgery, however, there is no any relevant retrieval literature found in the acupuncture field. It is feasible and practical of the expertise-based randomized controlled trial to be applied and promoted in the acupuncture-moxibustion clinical research for a further degree. Expertise-based randomized controlled trials might become the trend of acupuncture-moxibustion clinical stu dies in the future.

BACKGROUND: This study was undertaken to determine the prevalence of organ failure and its risk factors in patients with severe acute pancreatitis (SAP) . METHODS: A retrospective analysis was made of 186 patients with SAP who were had been hospitalized in the intensive care unit of Jinzhong First People's Hospital between March 2000 and October 2009. The patients met the diagnostic criteria of SAP set by the Surgical Society of the Chinese Medical Association in 2006. The variables collected included age, gender, etiology of SAP, the number of comorbidit, APACHEII score, contrast-enhanced CT (CECT) pancreatic necrosis, CT severity index (CTSI) , abdominal compartment syndrome (ACS) , the number of organ failure, and the number of death. The prevalence and mortality of organ failure were calculated. The variables were analyzed by unconditional multivariate logistic regression to determine the independent risk factors for organ failure in SAP. RESULTS: Of 186 patients, 96 had organ failure. In the 96 patients, 47 died. There was a significant association among the prevalence of organ failure and age, the number of comorbidity, APACHEII score, CECT pancreatic necrosis, CTSI, and ACS. An increase in age, the number of comorbidity, APACHEII score, CECT pancreatic necrosis were correlated with increased number of organ failure. Age, the number of comorbidity, APACHEII score, CECT pancreatic necrosis, CTSI and ACS were assessed by unconditional multivariate logistic regression. CONCLUSIONS: Organ failure occurred in 51.6% of the 186 patients with SAP. The mortality of SAP with organ failure was 49.0%. Age, the number of comorbidity, APACHEII score, CECT pancreatic necrosis, CTSI and ACS are independent risk factors of organ failure.
