Objective To study the application of doses of remifentail intravenous anesthesia in vocal nodule extirpation.Methods Sixty ASAⅠ～Ⅱpatients with vocal nodule were selected and randomly divided into three groups. Group F were given anesthetic induction with fentanil and maintenance with isoflurane; Group L were given anesthetic induction and maintenance with remifentail at the dose of 0.5?g/(kg?min); Group H were given anesthetic induction and maintenance with remifentail at the dose of 1?g/(kg?min).The anesthetic induction time,blood flow dynamics during maintenance phase,recovery time and quality were recorded. Results (1)Anesthesia produce less circulatory fluctuation in group H than in group F and L.(2) Group L and H were faster than group F on recovery profile including the time of response to verbal commands,autonomous breathing,tracheal extubation and discharging from operating room. The OAA/S score was higher in group L and H than in group F 5 min after intubation. There were no significant differences between group L and H. Conclusions Remifentanil intravenous anesthesia can achieve better recovery profile from anesthesia than fentanyl in vocal nodule extirpation. 1?g/(kg?min) remifentanil can inhibit the stress responses to tracheal intubation and laryngoscope inserted effectively with a stable circulatory function.

Objective To search for the normal value and developmental regular rule of motor norve conduction in children.Methods One hundred and fourty-nine children aged from 0 to 14 years old were divided into 7 groups in accordance with age. There were 19 pecrsons aged from 20 to 35 years old in adult group. The motor nerve conduction function of median nerve, ulnar perve, tibial nerve and peroneal nerve of every suhject was determined by nerve evoked potential meter.Results The terminal latency of action potential of every nerve is decreased along with growing up of age before 6 years old and increased after 6 years old. The conduction velocity of ulnar nerve is the fastest,then the peroneal nerve and median nerve, that of tibial nerve is the slowest. Median nerve development quicken after 3 months of birth and approch ulnar nerve at the time of 3 years old. Tibial nerye get into fast development period from 3 months to 1 years old and catch up peroneal nerve. The conduction velocity of every nerve extend to adult level in th period of 3~6 years old.Conclusion The every parameler of nervous conduction has a great difference of age in the period of child,particularly in that of infancy. therefore, the normal values should be set up in accordance with proper age groups. This study shows that it's suitable to divide groups in accordance with new-born, 3 and 6 months, 1, 3 and 6 years old. Adult criterion should be used in the children dbove 6 years old.

ObjectiveTo investigate the clinical phenotypes of familial hypercholesterolemia (FH) caused by exon 13 A606T mutation in low deusity lipoprotein receptor.MethodsClinical data of the suffered family were collected and analyzed,as well as measurement of perivascular intima-medial thickness and follow-mediated-dilation function by ultrasonography.ResultsThere were totally 11 sufferers including 4 males and 9 females,aged 8-90 years,with 2 homozygotes and 9 heterozygotes.Among them, one homozygote showed angina pectoris and hematuria,both homozygotes had skin xanthomata.TC,TG,LDL-C and HDL-C were(7.39 ± 1.30) mmol/L,(0.93 ± 0.36) mmol/L,( 11.76 ± 1.10) mmol/L and ( 1.22 ±0.17) mmol/L,respectively.The left/right sided intima-medial thickness of the common,internal,external and bulb carotid artery were ( 1.15 ±0.45) mm/( 1.30 ±0.60) mm,(0.82 ±0.30) mm/( 1.00 -0.66)mm,(0.77 ±0.28) mm/(0.78 ±0.30) mm and ( 1.40 ±0.59) mm/( 1.46 ±0.71 ) mm respectively.The brachial artery flow mediated dilation rate was (4.85 ±4.80)％.Echocardiography revealed 2 patients with cardiac valvular disease and 3 with atrium septum aneurysm.

Objective To analyze the colonization of Candida, Rhodotorula, Penicillium and Aspergillus in skin surfaces of patients with atopic dermatitis, and to assess the relationship between the four common fungal allergens and severity of atopic dermatitis. Methods Fifty patients with atopic dermatitis and 20 healthy controls were enrolled. Scales were scraped from lesional and non?lesional skin of flexural extremities of the patients, as well as from normal skin of the flexural elbow of healthy controls, then were subjected to microscopic examination and culture. Scale specimens were inoculated onto Sabouraud dextrose agar medium and cultured at 25 ℃ in a constant temperature incubator. Subsequently, suspected fungal or yeast?like colonies were collected for pure culture. Finally, fungal strains were identified according to colony morphology, color, growth speed, as well as microscopic features of spores and hyphae. Results No hyphae or pseudohyphae were found in any case by microscopic examination. Candida albicans and Rhodotorula were detected in 29(58%)and 17(34%)out of the 50 patients, respectively, and in 5(25%)and 2 (10%) out of the 20 healthy controls, respectively. The detection rates of Candida albicans and Rhodotorula were significantly higher in the patients than in the controls(χ2=6.23, 4.10, respectively, both P<0.05). Of 25 patients with severe lesions, 19(76%)and 12(48%)were colonized by Candida albicans and Rhodotorula respectively;among 25 patients with moderate lesions, 10 (40%) and 5 (20%) were colonized by Candida albicans and Rhodotorula respectively. An increase was observed in the detection rates of Candida albicans and Rhodotorula in the patients with severe lesions compared with those with moderate lesions(χ2=6.65, 4.37, respectively, both P<0.05). There was no significant difference in the detection rate of Penicillium or Aspergillus between the patients and health controls. Conclusion The colonization rates of Candida albicans and Rhodotorula on skin surfaces were higher in patients with atopic dermatitis than in healthy controls, and higher in patients with severe lesions than in patients with moderate lesions, indicating that the types of colonizing fungi are associated with the health status of skin and severity of symptoms in patients with atopic dermatitis.

Objective To discuss the value of high resolution MRI in the evaluation of small intralabyrinthine lesions with the symptom of vertigo. Methods We retrospectively analyzed the imaging examination techniques and imaging finding of 13 cases of labyrinthine hemorrhage or exudate and 6 cases of intralabyrinthine schwannoma (ILS) with the symptom of vertigo. Two cases of labyrinthine hemorrhage or exudate and 3 cases of ILS underwent temporal bone high resolution CT(HRCT) scan and all the 19 patients received highresolution MR examination. Patients of labyrinthine hemorrhage or exudate received fluid?attenuated inversion recovery (FLAIR)T2WI in addition to routine pre?contrast temporal bone MR. Pre?and post?contrast MR of the temporal bone were performed on the ILS patients. In particular, 3 ILS cases received three?dimensional sampling perfection with application?optimized contrasts by using different flip angle evolutions (3D?SPACE) sequence. Results There was no abnormal finding on HRCT of the inner ear of the 2 labyrinthine hemorrhage cases. On T1WI, regions of mild increased signal intensity of the labyrinth of affected side could be spotted in 7 patients whereas no abnormal signal intensity was found in the other 6 patients. On T2WI, all the 13 labyrinthine hemorrhage or exudate cases had no abnormal finding in the inner ear. On FLAIR T2WI sequence, regions of increased signal intensity of the labyrinth of affected side could be found in all the 13 cases. Thress ILS patients that received HRCT scan showed no valuable finding. On T1WI, no abnormal signal intensity was found in the labyrinth of the 6 patients. On T2WI, regions of decreased signal intensity of the labyrinth could be found in only 3 patients. All the 3 cases that received 3D?SPACE sequence appeared as a filling defect in the high?signal labyrinth clearly while 2 of the 3 lesions could not be found on T2WI. After Gadolinium administration, all the 6 ILSs were obviously enhancing. Conclusions High resolution MRI is valuable in the diagnosis of labyrinthine hemorrhage or exudate and ILS. The use of FLAIR T2WI sequence can help us to find labyrinthine hemorrhage or exudate more sensitively. The use of 3D?SPACE sequence can help us to detect and diagnose small intralabyrinthine lesions.

Objective To explore the bone mineral density (BMD) status and its influencing factors in schizophrenia patients in order to provide basis for risk assessment in psychiatric nursing.Methods A total of 1,139 hospitalized schizophrenia patients were recruited and assigned into the medication group (n=652) and the non-medication group (n=487) according to previous antipsychotic drug history.T-score and Z-score of BMD were determined using Sunlight Omnisense 7000S Bone Densitometry.Blood calcium,blood phosphorus and serum prolactin levels were measured using fasting blood of ulnar vein.Results Differences in age,BMD,milk intake,level of activity,level of smoking,history of fall,history of fracture,serum Ca2+ and PRL were statistically significant between two groups(P＜0.05);there were significant differences in BMD rank distributions among schizophrenia patients with different courses of disease and lengths of taking antipsychotics (P＜0.001);multiple linear regression showed that influencing factors of BMD with statistical significance were courses of disease,lengths of taking antipsychotics,serum Ca2+,serum PRL,milk intake,level of activity,and level of smoking.Conclusion The BMD was lower in the medication group than that in the non-medication group,and the development of osteoporosis was correlated to various factors.Clinical nurses should master high-risk factors thoroughly and adopt intervention measures in a timely manner.
