Objective To investigate the regulation of metabolize characteristic of some antibiotics in ACST in human bile, and provide the theoretic basis for physician selecting antibiotic rationally when biliary tract has been infected. Methods Samples of ACST in human bile were obtained by ERCP + ENBD, contents of Cefradine, Cefoperazone, Ceftriaxone, Ciprofloxacin and Lomefloxacin in human bile were simultaneously measured by HPLC method. Results After antibiotics were given through iv 0. 25 ～ 1. 5 hour, an increase was observed in contents of all antibiotics in bile, and the changes of Ceftriaxone and Ciprofloxa-cin were the most significant ( P <0.01). Ceftriaxone and Ciprofloxacin had a higher Cmax than other antibiotics, and Cefoperazone had a longer tl/2. Conclusion As maintaining a little time to tmax , a higher Cmax and a longer tl/2 in the bile by iv, Cefradine and Ciprofloxacin are recommended in the patient with ACST.

Objective To investigate the electromyngraphy eharacteristies of Parkinsen's disease (PD) by studying tremor frequency, intensity and drug response. Methods Sixty-six patients with PD hospitalized during March 2005 to May 2006 were re-evaluated and recruited into the study. A ten-channel electromyography recorded the frequency and intensity of the rest tremor and postural tremor. Tremor analysis soft was used to statistically analyze differences between the two types of tremor, correlation between the frequency and intensity, and changes after regular administration of dopaminergic medication. Results The frequencies of rest tremor ((4. 79±0.69 ) Hz) and postural tremor ( (5.54±1.18) Hz ) showed statistical differences (F = 33.5, P<0. 01), but the intensity of rest tremor (0.016-421.700 (rag)2) and postural tremor (0.062-217.900 (mg)2) didn't show statistical differences (F=1.917, P>0.05 ). No regression relation was revealed between the frequency and intensity of tremor (r=0.09, P>0.05). After dopaminergic medication treatment, the intensity declined significantly from 0.016-421.700 (mg)2 to 0.027-82.200 (mg)2(F=5.179,P <0.05), but the difference of frequencies of tremor between before ( (5.09±0.85) Hz) and after treatment ( (5.20 ± 1.08 )Hz) was not significant (F = 0.474, P > 0.05). Conclusions There may be different mechanisms for the rest tremor and postural tremor in PD. There is no correlation identified between the frequency and intensity in PD and this is may be resulted from variability of tremor intensity. Dopaminergic can relieve the symptom of tremor, but it doesn't reduce the frequency of tremor.

Objective To investigate the clinical characteristics of tuberculous pleurisy(TP) in children in order to provide a good solution to the diagnosis and treatment of this disease.Methods Retrospective analysis was performed on the clinical data of 113 cases confirmed with TP who were admitted to Children's Hospital of Chongqing Medical University from January 2009 to December 2014.Results Among the 113 pediatric inpatients with TP,85 cases (75.2％) were sick for less than 1 month;92.9％ (105/113 cases) age ≥≥5 years old by onset;and 21.2％ (24/113 cases) patients demonstrated the contact with tuberculosis ,among whom 70.8％ (17/24 cases) attributed to linear relatives.The primary clinical manifestations included fever[96.5％ (109/113 cases)], cough [76.1％ (86/113 cases)] and chest pain[38.9％ (44/113 cases)] ,with as high as 89.0％ (87/109 cases) of the patients experiencing moderate or ardent fever.The positive rates of acid-fast bacilli smear and mycobacterium tuberculosis culture were 12.2％ (17/139 cases) and 22.7％ (15/66 cases), respectively;among the 41 patients who received pleural biopsy,40 cases (97.6％) were identified with the typical pathological changes in tuberculosis;and all 11 patients who received acid fast stain test on pleural tissues were positive to the test.Pulmonary parenchymatous lesions were revealed on CT examination in 89.1％ patients(98/113 cases),82.4％ (90/109 cases) of the patients had normal body temperature within a short period,and reduced effusion was revealed in 86 out of 98 patients who received repeated chest imaging examinations.Conclusions TP in children has acute onset typically, and the diagnosis of TP in children is more difficult than in adults,requiring considering multiple factors.Contact history with tubercular patients, etiological examination, pleural biopsy and chest CT are essential for the diagnosis of this disease.

Objective To investigate the effect of dexmedetomidine on excitatory aminoacid (EAA)and inhibition of amino acid(IAA)in cerebro-spinal fluid(CSF)of patients undergoing in-tracranial tumor surgery,and to explore the cerebral protective mechanism of dexmedetomidine in neurosurgery.Methods Sixty patients aged 18-64 years old,ASA Ⅰ or Ⅱ,weighing 50-90 kg un-dergoing elective intracranial tumor surgery were randomly divided into dexmedetomidine group (group D)and control group(group C).Dexmedetomidine 1 μg/kg was infused before anesthesia in-duction for more than 10 minutes and pumped continously with 0.2-0.7 μg·kg-1·h-1 in group D, while in group C midazolam 0.03-0.05 mg/kg was injected followed by intermittent administration of 0.03-0.05 mg/kg.BIS value was maintained between 40-50.MAP and HR was recorded at the time points before induction(T0 ),dura mater incision(T1 ),tumor resection(T2 ),at the end of the surgery (T3 ).And we collected CSF at T0 ,T3 ,6 hours after the surgery(T4 ),12 hours after the surgery (T5 ),24 hours after the surgery(T6 ),then the concentrations of EAA and IAA were determined with high-performance liquid chromatography (HPLC)at T0 ,T3 ,T4 ,T5 and T6 .Results The MAP and HR in group D at T1-T3 were much lower than that in T0 and in group C(P <0.05).Compared with T0 ,the Glu and Asp in CSF significantly increased in group C at T3-T6 and were much higher than those in group D (P < 0.05 ),GABA was significantly decreased and much lower than group D(P <0.05).Compared with T0 ,the Glu and Asp in group D at T3-T5 were increased and GABA was decreased, but without statistic significance. At T6 , the values recovered to the level at T0 . Conclusion Dexmedetomidine can be used to maintain hemodynamic stability in intracranial tumor surgery,and may play a role in cerebral protection through inhibiting expression of Glu and Asp (EAA).

Objective To observe the effects of ketamine on the patients with depression re-ceiving modified electric conulsive therapy (MECT).Methods Sixty patients with depression were randomly divided into ketamine group and propofol group (n =30 each group).Atropine 0.5-1.0 mg, propofol 1.0 mg/kg or ketamine 0.8 mg/kg i.v.were given before MECT,Scoline 0.7-1.0 mg/kg i. v.was given after the eyelash reflex disappeared.Hamilton Depression Rating Scale (HAMD)was completed after the 2 nd ,4 th and 6 th MECT,the time of convulsion,twitch index,energy percentage, respiratory recovery time and adverse reactions were recorded.Results The total score of HAMD was significantly decreased with the increasing times of MECT in both groups,compared with propo-fol group,ketamine group's HAMD total score decreased faster,especially after the 4th MECT,the score decreased significantly in ketamine group (P <0.05).The time of convulsion,twitch index,en-ergy percentage, respiratory recovery time, adverse reactions all had no statistical significance between the two groups.Conclusion Compered with propofol,ketamine,as an anesthetic of MECT, can effectively lower the score of HAMD.

Objectives To investigate the effects of ethanol on neural development and kainate receptor expression in young mice. Methods Fetal alcohol spectrum disorder model was established by administration of 20% ethanol solu?tion to 7-day-old Kunming mice and control animals received physiological saline (The number of treatment and control were 80 and 40, respectively ). Body weight and general biological features were observed every day. Morris water maze was used to test learning and memory ability. Fluoro-Jade B was used to examine neural cells 24 hours after treatment in additional thirty 7-day-old Kunming mice which were further divided into two groups:a treatment group receiving 20%ethanol solution (n=15) and a control group receiving physiological saline (n=15). The development of neural cells and expression levels of kainite receptors were examined by using immunofluorescence staining. Results The body weight was significantly lighter in treatment group than in control group(control:21.13 ± 1.72g,treatment:13.96 ± 2.98g,P<0.05). Morris test showed that model group had longer latency than control group to find hidden platform(control:21.05± 5.31s,treatment:34.15±3.26s,P<0.05). Spatial probe test revealed that the number of passing through the platform were significantly smaller in model group than in control group(control:2.70 ± 1.25 times,treatment:0.93 ± 0.80 times,P<0.05). Astrocyte development anomaly was evident after ethanol treatment for 7 days. The expression levels of kainite re?ceptor GluR-6 and KA2 were up-regulated in the CA region of the hippocampus after ethanol treatment for 7 days. Con?clusion Kainite receptor GluR-6 and KA2 in CA region of the hippocampus may contribute to ethanol-induced hippo?campal neural development anomaly.

Objective The article was to observe the clinical efficacy of the application of terbinafine and mizolastine in com -bined treatment of chronic eczema ( CE) with dermatophytes infection , so as to define the etiology role of dermatophytes in allergic dis-eases. Methods All subjects were randomly divided into experiment group and control group .The experiment group was treated with the combination of terbinafine and mizolastine , while the control group took mizolastine orally alone .EASI grading , recovery rate and effective rate were evaluated at 2, 3 week after the treatment and EASI grading and recurrence rate were evaluated at 4 weeks after the treatment. Results 79 patients had finished the experiment .Significant difference was found in the effective rates between two groups at 3 weeks after treatment (P<0.05).At 4 weeks after the treatment, EASI value and recurrence rate in experiment group were obviously lower than those in control group (P<0.05). Conclusion Good therapeutic effect has been achieved through the ap-plication of terbinafine and mizolastine in combined treatment of CE with dermatophytes infection , which implies dermatophytes plays an important role in the etiology of CE .

Objective To investigate the clinical efficacy of combined detection of VCA-IgA and Rta-IgG in the diagnosis of nasopharyngeal carcinoma.Methods From May 2013 to November 2014, 3 913 serum samples(male 2 367,female 1 546) from healthy people who had health examination in our medical center were collected and 169 serum samples(male 118,female 51) were collected from the patients who were diagnosed as nasopharyngeal carcinoma by pathological biopsy.Serum samples in two groups were detected by EBV RTA-IgG, VCA-IgA assay ( ELISA ) respectively.SPSS17.0 statistical software and receiver operating characteristic curve ( ROC) were applied to data analysis.Results The Rta-IgG positive rates of EB virus were 93.5%in NPC group (158/169) and 2.4%(93/3 913) in healthy group;while the VCA-IgA positive rates were 79.3%in NPC group ( 134/169 ) and 8.9% ( 349/3 913 ) in healthy group. The sensitivity(χ2 =14.49,P<0.05) and specificity(χ2 =157.15,P<0.05) of Rta-IgG in the diagnosis of nasopharyngeal carcinoma were significantly better than that of VCA-IgA. Using VCA-IgA/Rta-IgG combined detection analysis, not only failed to effectively improve the diagnosis of nasopharyngeal cancer, but to reduce the detection sensitivity to 72.8%( 123/169 ) , compared with Rta-IgG detection only. Conclusions Rta-IgG is significantly better than that of VCA-IgA.There was no significant improvement in the clinical diagnostic efficacy of nasopharyngeal carcinoma using VCA-IgA/Rta-IgG combined detection mode.

Objective To examine the effectiveness of simulation newborn simulator in neona-tal resuscitation training for pediatric residents. Methods From June 2011 to June 2012, 11 residents working in neonatal ward of the Third Hospital of Peking University were enrolled into the study. Eval-uation on the residents was made before the training. Training of simulated teaching using simulation newborn simulator was conducted and evaluation was made after the training. SPSS 18.0 was used for statistical analysis. Comparison was made between pre- and post-training test by paired t test. P<0.05 was considered statistical significant. Questionnaire survey was conduct to acquire residents' feedback. Results A total of 11 participants completed the training and finished the questionnaire. The score of pre-training was 37.82±1.17 versus that of post-training 39.18±0.87(t=4.89, P<0.01). All residents were satisfied with the simulation-based training. Conclusion Simulation training can improve pedi-atric residents' knowledge and skills in neonatal resuscitation.

Objective To investigate the colonization features of Staphylococcus aureus (S. aureus) in the skin lesions of eczema and atopic dermatitis (AD), and to evaluate the therapeutic effect of combination topical treatment with mupirocin and hydrocortisone butyrate. Methods A multicentre, double-blind randomi-zed trial was conducted. The SCORAD was evaluated on day 1, 7, 14 and 28. Swabs for bacterial isolation were taken from the lesional skin and non-lesional skin. A combination topical therapy with mupirocin ointment and hydrocortisone butyrate ointment was used in treatment group, with vehicle ointment and hydrocortisone butyrate ointment as a control. Results Three hundred and twenty seven patients were enrolled in the study, including 208 patients with eczema and 119 patients with atopic dermatitis. Bacteria were isolated from 70.19% of lesional skin and 32.69% of non-lesional skin of patients with eczema, in which S. aureus accounted for 47.26% and 27.94% respectively. Bacteria were isolated from 74.79% of the lesional skin and 34.45% of non-lesional skin of patients with atopic dermatitis, in which S. aureus accounted and 79.78% or 80.49% respectively. The amount of S. aureus colonized was markedly higher in the lesional skin than that in non-lesional skin, either in eczema patients or in atopic dermatitis (P 0.05). Conclusions The bacterial colonization, especially S. aureus, is more frequently dectected in the lesional skin of eczema patients and AD patients than that in the non-lesional skin, which may be related in the pathogenesis of eczema and AD. And, early application of combination therapy with topical antibiotics and corticosteroids is beneficial to the patients.
