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. ConclusionFH patients show a variety of phenotypes incuding extraordinary hypercholesterolemia,subcutaneous xanthomata and premature coronary heart disease.

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 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.

Objective To evaluate the cleanliness and tolerance of different administration speed on polyethylene glycol electrolyte solution (PEG-ES) for colonoscopy preparation. Methods 97 consecutive asymptomatic individuals underwent colonoscopy and therapy were enrolled and randomly assigned into 2 groups. Subjects in group A drank 2000 ml PEG-ES (1000 ml every 10 ~ 20 min rapidly) within 1 h before colonoscopy;Subjects in group B drank 2000 ml PEG-ES (250 ml every 10 min) within 2 h before colonoscopy. The total time of drinking PEG-ES, the first defecation time and total numbers of defecation after drinking PEG-ES, score and degree of Boston bowel preparation scale (BBPS) and PEG-ES related adverse effects of the two groups were assessed and compared. Results There were no significant differences in gender, age and cecal insertion rate between group A and group B (P > 0.05). The total time of drinking PEG-ES, the first defecation time in group A were significant faster than those in group B, while total numbers of defecation was significantly more than that in group B (P < 0.05). No patients in the two groups complained PEG-ES related bellyache and vomiting, a little subjects in group B complained PEG-ES related nausea and bloating (P < 0.05), but the incidence were both less than 10.00 %. Accepting rate of colonoscopy preparation in group A was lower than that in group B, but both more than 90.00%, while accepting rate of re-colonoscopy than that in group B. BBPS score of the right half colon, transverse colon, total colon were significantly higher in group A than that in group B respectively (P < 0.05), while that of the left colon no significant differences between the two groups (P > 0.05). Conclusions Both regimens met the requirement of conventional colonoscopy and therapy, while rapid drinking PEG-ES within 1 h provides more better colonic cleansing quality for colonoscopy preparation.
