Objective To examine the characteristics of dysfunctional attitudes in patients with so?matoform disorders and to delineate the relationship between dysfunctional attitudes and personality disorder tendency. Methods Sixty?four outpatients with somatoform disorder and 52 healthy individuals were recrui?ted and asked to complete the Personality Diagnostic Questionnaire( PDQ?4) and the Dysfunctional Attitudes Scale( DAS ) for the evaluation of their personality disorder tendency and cognitive characteristics. DAS scores were compared between patient and control groups. The relationship between DAS and PDQ?4 was e?valuated by comparing DAS scores of patients with and without personality disorder tendency and by correla?ting patients’ total scores of DAS and PDQ?4. Results Patients with somatoform disorder(150.13±31.75) showed significantly higher scores of DAS than healthy controls(121.62±20.30). Moreover,patients with per?sonality disorder tendency exhibited significantly higher scores in the total score of DAS and scores of five factors including vulnerability, absorption/exclusive, compulsion, dependence and cognitive philosophy ( P<0.05) . Finally,a positive correlation was found between total scores of DAS and PDQ?4( r=0.535, P<0.01) and the correlation coefficients between the total score of DAS and Cluster A( r=0.545) and C scores( r=0.625) were significantly higher than that of Cluster B score( r=0.317).Conclusion Patients with somato?form disorders have cognitive distortion,which is correlated with personality disorder tendency.

Objective To study the incidence of rapid eye movement sleep behavior disorder (RBD) and its impact on the clinical manifestations of patients with Parkinson' s disease (PD). Methods One hundred and twenty-four PD patients were included into this study and each of them was given the non motor symptoms questionnaire (NMSquest) to investigate the incidence of RBD. The PD patients were then divided into the RBD group and non RBD group, according to their answers to the NMSquest. Then the clinical differences were investigated between PD patients with and without RBD on the aspects of demographic characters, Hoehn-Yahr (H-Y) stage, the scores of Unified Parkinson Disease Rating Scale (UPDRS) sub-items, the incidence of non motor symptoms, and the dysfunctions of non motor systems (cognitive impairment, anxiety, depression and sleep disorders ). The evaluation tools of non motor functions include Mini Mental State Exam ( MMSE), Hamilton Depression Scale (HAMD), Parkins' s Disease Sleep Scale (PDSS) and Epworth Sleepiness Scale (ESS). Results ( 1 ) 62.9% (78/124) of the PD patients have been experiencing RBD. (2) The course of the disease in RBD group ( 3.8 ± 2.8 ) was significantly shorter than non RBD group (5.0 ± 2.5, t = - 1. 972, P = 0. 048 ) while the sex, age, onset age and the mode of onset, Levodopa dose equivalents (LDE) and the kinds of medicines showed no difference between the two groups. (3) H-Y stage, the scores of UPDRS sub-items and the incidence of motor complications showed no difference between RBD and non RBD group. (4) Most of the non motor symptoms, including the gastrointestinal dysfunctions, autonomic dysfunctions, mood disorders and sleep disturbances, occurred much frequently in RBD group, however, the scores of MMSE, HAMD, HAMA,PDSS and ESS showed no difference between the RBD and non RBD group. Conclusion RBD commonly occurred in PD patients, and PD patients with RBD have a tendency to suffer from dysfunction of non motor systems.

Objective To establish RT-PCR-RFLP method for studying the genotype of wild mea-sles virus strains isolated from Tianjin area from 2002 to 2008. Methods Isolations of measles virus were carried out by tissue culture method from urine and throat swab specimens collected from suspected cases. RNA were extracted from the virus specimens. The 594 bp fragment of C terminal of the N (nucleoprotein) gene was amplified by one-step RT-PCR, then the PCR products were digested with Bcn I , separated on agarose gel electrophoresis and then analyzed by the method of RFLP (restriction fragment length polymor-phism). In addition, above results were compared with DNA sequencing. Phylogenetic tree was plotted based on the results for the genetic relationship and distance analysis. Results Sixty-nine measles virus strains were isolated from 189 specimens from 2002 to 2008, of which the C terminals of N gene were all de-tected positive. Among the 69 strains of measles virus isolates, 98.55% (68/69) belonged to Hla sub-geno-type which was the predominant sub-genotype, and only one strain (1.45%) belonged to H1b sub-genotype by RFLP analysis which was in accordance with the results by DNA sequencing method. Phylogenetic tree analysis indicated the H1a sub-genotype measles virus strains should be further divided into 2 clades, and the variation fluctuated between 0.2% and 3.8%. There were transmission chains caused by different virus strains co-cireulation. Conclusion A genotype, H1a and H1b sub-genotype can be identified by RT-PCR-RFLP assay specically based on the restriction enzyme Bcn I .The RT-PCR-RFLP assay can be a rapid, simple, accurate and efficient method for large-scale surveillance of measles virus strains in China.

Objective To study the effects of permissive hypercapnia (PHC) on inflammatory factors of pulmonary tuberculosis patients with one-lung ventilation (OLV).Methods Sixty pulmonary tuberculosis patients with selective thoracic operation who were hospitalized at Hangzhou Red-cross Hospital from October 2010 to October 2013 were randomized into three groups by means of random digits table.Twenty patients were enrolled as control group whose arterial partial pressure of carbon dioxide (PaCO2) was maintained at 35-45 mmHg (1 mmHg=0.133 kPa),20 patients as lower PHC group whose PaCO2 were maintained at 50-55 mmHg,and 20 patients as higher PHC group whose PaCO2 were maintained at 56-60 mmHg.The concentrations of serum interleukin (IL)-6 and IL-8 were measured at the time when the patients were in supine position by two-lung ventilation after induction of anesthesia (T1),15 minutes (T2) and 30 minutes after OLV (T3) in lateral position,two hours (T4) and 6 hours after operation (T5).Quantitative data were analyzed by t-test.Results IL-6 at T3 time point in the three groups increased significantly compared with T1 time point (control group:[4.94± 1.60] pg/mL vs [3.32±1.34] pg/mL,t=3.47,P＜0.01; lower PHC group:[5.38±1.42] pg/mL vs [3.69±1.35] pg/mL,t=3.86,P＜0.01; higher PHC group:[5.57±± 1.34] pg/mL vs [3.50 ± 1.22] pg/mL,t=5.11,P＜0.01).IL-8 at T4 time point increased significantly compared with T1 time point (control group:[342.09±56.12] pg/mL vs [194.58 ± 30.07] pg/mL,t =10.36,P＜0.01; lower PHC group:[349.48±43.49] pg/mL vs [193.16±26.27] pg/mL,t=13.80,P＜0.01; higher PHC group:[351.55±38.13] pg/mL vs [186.02±21.08] pg/mL,t=16.99,P＜0.01).IL-6 at the T4 and T5 time points in both lower PHC group and higher PHC group decreased significantly compared with control groupatthe same time points (T4..[38.49± 9.70] and [43.41± 9.01] pg/mL vs [62.35±7.83] pg/mL,t=8.56 and 7.10,both P＜0.01; T5:[56.39±7.47] and [54.77±7.12] pg/mL vs [107.32± 13.97] pg/mL,t=-14.38 and-14.99,both P＜0.01].Conclusions The serum IL-6 and IL-8 levels in pulmonary tuberculosis patients with OLV increase after selective thoracic operation.PHC through low tidal volume could decrease the release of IL-6 and attenuate the pulmonary inflammatory injury in the tuberculosis patients with operation.

Objective To determine the dose-response relationship of sufentanil blunting responses to double-lumen endotracheal intubation when combined with propofol given by target-controlled infusion (TCI) in patients with pulmonary tuberculosis.Methods One hundred patients of both sexes with pulmonary tuberculosis,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 24-58 yr,with body mass index ＜30 kg/m2,with Mallampati grade Ⅰ or Ⅱ,undergoing thoracic surgery under general anesthesia,were divided into Ⅰ-Ⅴ groups (n =20 each) using a random number table.Anesthesia was induced with iv sufentanil 0.35 μg/kg (group Ⅰ),0.40 μg/kg (group Ⅱ),0.45 μg/kg (group Ⅲ),0.50 μg/kg (group Ⅳ) and 0.55 μg/kg (group Ⅴ),and propofol TCI (target plasma concentration 3.5 μg/ml) and iv vecuronium 0.15 mg/kg.The patients were endotracheally intubated and mechanically ventilated.The response to double-lumen endotracheal intubation was defined as positive when mean arterial pressure increased by＞ 20％ of the baseline value and/or heart rate ＞ 90 bpm within 5 min after intubation.The median effective dose (ED50),ED95 and 95％ confidence interval (95％ CI) of sufentanil blunting the responses to double-lumen endotracheal intubation were calculated by Probit analysis.Results The ED50 (95％ CI) and ED95 (95％ CI) of sufentanil blunting the responses to intubation were 0.411 (0.370-0.441) μg/kg and 0.635 (0.556-0.888) μg/kg,respectively,when combined with propofol given by TCI.Conclusion When combined with propofol given by TCI (target plasma concentration 3.5 μg/ml),the ED50 and ED95 of sufentanil blunting the responses to double-lumen endotracheal intubation are 0.411 and 0.635 μg/kg,respectively,in patients with pulmonary tuberculosis.

Objective To assess the development,progression and change of nonmotor symptoms in patients with Parkinson' s disease and its impact on patients' quality of life.Methods Eighty-seven consecutive patients with idiopathic Parkinson' s disease were studied.Parkinsonian status was assessed at baseline and 3 years follow-up using Unified Parkinson' s Disease Rating Scale (UPDRS) part Ⅲ & Ⅳ,Nonmotor Symptoms Questionnaire (NMSQuset),Parkinson-related quality of life (PDQ) scales.Paired ttest,Chi-square test,Spearman rank order correlation and hierarchical regression of the major statistical procedures were employed.Results At 3 years follow-up,compared to baseline,the UPDRS Ⅲ score (22.21 ±11.31 vs 30.49± 11.68),UPDRS Ⅳ score(1.00±1.54 vs 2.94±3.12),NMS score (7.98±3.96 vs 12.35 ± 5.12) and PDQ score (28.11 ± 22.88 vs 36.65 ± 26.95) were significantly higher ( t =- 5.54,- 5.75,- 6.46,- 5.29,all P =0.000,respectively).The aggravation of motor and nonmotor symptoms caused the decline of quality of life.The prevalence of constipation,problem of remembenng thing,nocturia ranked tops,and depression,and anxiety were still in the middle,compared with baseline.The prevalence of pains,sweating,dribbling,sense of incomplete emptying etc were significantly increased during the follow-up,△R2 were 21.6％ and 23.4％ respectively,resulting in the deterioration of quality of life.Conclusions PD nonmotor symptoms appear from the early stage.The motor and nonmotor symptoms aggravate over time.

Objective To observe progression of motor symptoms and occurrence of motor complications in parkinsonian patients and investigate the rate of progression of motor symptoms and risk factors of motor complications.Methods One hundred and thirty patients diagnosed with PD in 2007 in Department of Neurology,Xinhua Hospital were followed up for 3 years.The Unified Parkinson' s Disease Rating Scale (UPDRS) and H-Y staging were used to assess and follow up motor symptoms and occurrence of motor complications,and analyze the rate of progression of motor symptoms and risk factors of motor complications with statistics.Results ( 1 ) Mean annual growth in H-Y staging was 2.5％,and UPDRS motor scores was 3.1％ ; the incidence of dysphagia at endpoint in patients was increased by 23.0％ compared with baseline; incidence of falls was increased by 16.7％;(2)Daily levodopa dose at endpoint ( OR =1.004,95％ CI 1.001—1.006,P =0.008 ) was independent risk factors with dyskinesia; While duration ( OR =1.637,95％ CI 1.083—2.473,P =0.019 ),levodopa treatment duration ( OR =0.698,95％ CI 0.494—0.987,P =0.042 ),daily levodopa dose at haseline ( OR =1.005,95％ CI 1.001—1.010,P =0.016) and at endpoint ( OR =1.014,95 ％ CI 1.001 —1.027,P =0.032 ) were risk factors with motor fluctuations.Conclusions As the disease progresses,motor function in parkinsonian patients gradually worsens,the incidence of swallowing difficulty and of falls is increased,and the incidence of motor complications is increased.The total exposure to levodopa in parkinsonian patients is predictor for motor complications.

Objective To derive a questionnaire to assess the risk of developing motor complications through a 3-year prospective investigation on 71 patients of Parkinson' s disease (PD) in the out clinic at our hospital.Methods Three years after the first assessment,71 PD out patients were reassessed using various scales,including Unified Parkinson Disease Rating Scale,Hoehn-Yahr grade,Mini Mental State Exam,Hamilton Depression Scale and Hamilton Anxiety Scale.Results The incidence of motor complications was 43.6％ (31/71).Logistic regression analysis showed that the prognostic factors for motor fluctuation were age of onset ≤ 54 (OR =6.4,95％ CI 1.7-24.5,P =0.006),the occurrence of swallowing difficulty (OR =3.8,95 ％ CI 1.0-14.1,P =0.04) and depression (OR =4.0,95 ％ CI 1.1-13.7,P =0.03),and the prognostic factors for dyskinesia were age of onset ≤54 (OR =48.5,95％ CI 1.9-121.0,P:0.02),the occurrence of falling (OR =64.1,95％ CI 2.9-142.2,P =0.008) and the daily levodopa dosage ＞ 600 mg(OR =17.5,95％ CI 1.1-276.2,P =0.04).Based on the regression model,the assessment questionnaire for motor complicationsincludes the followings:the questionnaire for motor fluctuations:the age of onset ≤54,2 points; the occurrence of swallowing difficulty,1 point; the occurrence of depression,1 point; the questionnaire for dyskinesia:the onset age ≤54,2 points; the occurrence of falling,3 points; daily levodopa dosage ＞ 600 mg,2 points.In all patients in this study,21.7％ (10/46) was asscssed to a total scorc of 0-1 which is associated with a low risk of motor fluctuation,8/16 had a score of 2 which is associated with intermediate risk and 8/9 got a score of 3-4 associated high risk; 10.2％ (5/49) had a score of 0-2,a low risk of dyskinesia,4/13 had a score of 3-4,a intermediate risk and 7/9 got a score of 5-7 which is associated with a high risk.Conclusions Age onset ≤54,the occurrence of swallowing difficulty,falling and depression,daily levodopa dosage ＞ 600 mg were considered to be the prognostic factors of motor complications in PD.The questionnaire may help to stratify PD patients into low-risk,medium-risk and high-risk groups for motor complications and the higher the score in the questionnaire is related to the higher risk of motor complications.
