OBJECTIVE: To investigate the effect of transurethral resection of prostate (TURP) on the quality of life in aged patients with benign prostatic hyperplasia(BPH). METHODS: Altogether 358 BPH patients were evaluated by International Prostate Symptom Score (IPSS), the 5-Item Version of the International Index of Erectile Function (IIEF-5),Quality of Life Scale (QOLS) questionnaires, Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS),residual urine volume (RUV), and maximum flow rate(Qmax) before and at 3 months after they underwent TURP. RESULTS: The mean scores of IPSS, QOLS, SAS, and SDS, and mean RUV decreased, and mean Qmax increased significantly at 3 months after receiving operation compared with those before the treatment in aged patients with BPH. But no significant difference was found in the scores of IIEF-5 between post-operation and pre-operation. CONCLUSION TURP may alleviate BPH clinical symptoms and improve quality of life, but may not be helpful to the recovery of sexual function in aged patients with BPH.

OBJECTIVETo investigate the changing of T4 5'-and 5-deiodinase within rat brain under various iodin-nutritional states.

METHODSAnimal model of iodine-deficiency rat was performed and the rats were divided into 4 groups by the intake of iodine-nutrition, and then killed at an age of 20 days. The thyroid hormones level in serum was measured by ELISA and the activity of T(4) 5'-and 5-deiodinase within brain was analyzed.

RESULTSIn less-iodine (LI) group,TT4 and FT4 were accounting for 3.5% of the neutral-iodine (NI) group's, and FT3 was 174.0% of NI group's (P < 0.05). In NI group,TT4 and FT4 were 114.5% and 127.7% of NI group's (P < 0.05). In high-iodine (HI) group, TT4 and FT4 were 61.86% and 62.0% of NI group's, and FT3 was 184.9% of NI group's (P < 0.05). In LI group, the activity of T4 5'-deiodinase tissue of per gram (1.95 +/- 0.32) ngT3.microgT4(-1).h was significantly higher than that of NI group (P < 0.05), and the activity of 5-deiodinase (1.38 +/- 0.21) ngrT3.microg T4(-1).h(-1) is significantly less than that of NI group (1.59 +/- 0.23) (P < 0.05). In HI group the activity of T4 5'-and 5-deiodinase tissue of per gram (1.12 +/- 0.19 and 1.73 +/- 0.36) ngrT3.microgT4(-1).h(-1)was significantly less than that of NI group (P < 0.05).

CONCLUSIONThe activity of T4 5'-deiodinase in iodine deficiency heightens and that in iodine excess is debased, the activity of T4 5-deiodinase in iodine deficiency and in iodine excess is debased.

OBJECTIVETo study the validity of criteria currently used in China for the classification of symmetric small for gestational age infants (SGA) as compared with its definition.

METHODSThis study included 417 inpatients diagnosed as SGA in authors' hospital from January 1998 to June 2002. Symmetric SGA was diagnosed by the following three criteria: (1) the Ponderal Index (PI), (2) the crown-heel length-to-head circumference ratio (BL/HC) issued in Chin J Pediatr (1988;26:164 - 165), as well as (3) the SGA definition. The definition criterion was considered as the "gold standard". The sensitivity, specificity, false positive and negative values, positive and negative predictive values, exact agreement ratio, diagnosis index, and Cohen's Kappa value were used to evaluate the validity and agreement of the methods of PI and BL/HC. Receiver Operating Characteristic (ROC) analysis was used to evaluate the validity of the diagnosis.

RESULTSOf 417 SGA infants, 376 (90.17%), 376 (90.17%) and 187 (44.84%) subjects were diagnosed as symmetric type with PI, BL/HC and the definition criteria, respectively. (2) The agreement rate and Kappa value between PI and BL/HC was 80.82% and -0.093 (SEM 0.026), respectively. And the agreement rates between PI or BL/HC and the definition criterion were 49.88% and 50.84%, respectively. As compared with the definition criterion, the PI and BL/HC methods had sensitivities of 91.8% - 96.4%, specificities of 9.3% - 25.9%, positive predictive values of 45.8% - 51.1%, negative predictive values of 72.7% - 82.8%, diagnosis indices of 4.9% - 17.7% and Kappa values of 0.070 - 0.167. (3) The areas under the ROC curves in full-term and preterm infants by PI method were 0.635 (95% CI, 0.573 - 0.697) and 0.698 (95% CI, 0.622 - 0.725), respectively. PI cutoffs at 2.47 in full-term SGA, at 2.43 in preterm SGA, and BL/HC cutoff at 1.43 produced the maximum diagnosis indices that were 24.7%, 39.6% and 33.7%, respectively. When the PI at 2.50 (full-term), PI at 2.31 (preterm) and BL/HC values at 1.46, the sensitivity closed mostly to the specificity. The sensitivities and specificities in full-term and preterm infants were 59.4% and 59.3%, 65.3% and 65.5%, and 66.3% and 65.5%, respectively.

CONCLUSIONIn the classification of SGA, the results showed a poor agreement between PI or BL/HC and the definition criterion. The results suggested that the current cutoffs of PI and BL/HC might not be appropriate for the diagnosis of symmetric SGA. Low AUC suggested that PI and BL/HC could not give a valid diagnosis at any cutoffs.

OBJECTlVE To investigate the mechanism of verapamiI in the treatment of type 2 Iong QT syndrome(LQT2)using a rabbit Ieft ventricuIar myocardiaI wedge preparation. METHODS E-4031 (0.5 μmoI·L-1 )was used to induce the LQT2 modeI after rabbit Ieft ventricuIar wedge preparations were equiIibrated for 1 h,and verapamiI(0.5,1.0 and 2.5 μmoI·L-1 ,respectiveIy)was perfused in different groups. Data were coIIected for a period of 30 min starting 30 min after adding the respective drug. Transmembrane action potentiaIs of endocardiaI and epicardiaI myocardium were recorded simuItaneous-Iy at a basic cycIe Iength of 2000 ms(S1S1)together with a transmuraI ECG. The effect of verapamiI (0.5,1.0 and 2.5 μmoI·L-1 )on action potentiaI duration at 90% repoIarization(APD90 ),QT intervaI, transmuraI dispersion of repoIarization(TDR)and the deveIopment of earIy afterdepoIarization(EAD) and torsades de pointes(TdP)were evaIuated in the LQT2 myocardiaI wedge modeI. RESULTS E-4031 (0.5 μmoI·L-1 )markedIy proIonged endocardiaI and epicardiaI APD90 and QT intervaI( P﹤0.01),and dramaticaIIy increased TDR(P﹤0.01). Spontaneous or programmed eIectricaI stimuIation-induced EAD and TdP were aIso observed in the modeI. VerapamiI(0.5,1.0 and 2.5 μmoI·L-1 )dose-dependentIy abbreviated endocardiaI and epicardiaI APD90 and QT intervaI(P﹤0.01),significantIy decreased TDR(P﹤0.01),and suppressed EAD and TdP in the LQT2 modeI. Concordant but stronger effects on the eIectro-physioIogicaI properties of the LQT2 modeI were noticed when nifedipine was perfused. CONCLUSlON VerapamiI inhibits TdP in the LQT2 modeI by reducing TDR and suppressing EAD.

Objective To investigate the characteristics of infecting pathogens,their changes and antimicrobial susceptibilities on CAPD related peritonitis in our peritoneal dialysis(PD) center in the past 15 years.Methods Two hundred and six CAPD related peritonitis episodes in 145 patients from 2000 to 2005 were analyzed and compared with 109 episodes from 1991 to 2000.The causative pathogens,their antimicrobial susceptibilities and outcomes on CAPD related peritonitis from the two periods were retrospectively reviewed and compared.Results Culture negative rate decreased from 60.6% in 1990 s to 47.6% in the last five years (P=0.031 ).Among culture positive peritonitis episodes,the incidence of gram positive bacteria (GPB) peritonitis increased from 25.6% to 39.8% (P=0.059).This was mainly due to a significant increase in coagulase-neagative staphylococcus peritonitis,which significantly increased from 4.7% to 26.9% (P=0.01).Gram negative bacteria (GNB) peritonitis decreased slightly (44.2% vs 34.3%,P=0.322).The incidence of Klebsiella pneumoniae peritonitis significantly decreased (14.0% vs 3.7%,P=0.023),while Pseudomonas aeruginosa and Escherichis coli peritonitis rates slightly increased (4.7% vs 9.3%,P = 0.338;7% vs 18.7%,P=0.072).The decrease of fungal peritonitis rate was not significant (30.2% vs 17.6%,P= 0.123).The comparison of clinical outcomes showed an improvement of total recovery rate from 68.8% in 1990 s to 73.9% for 2000-2005 (P=0.09).The catheter removal rate decreased from 19.2% to 14.3% (P=0.238),and the mortality from 10.1% to 5.4% (P=0.118).In both periods,fungal peritonitis had the poorest results,which all the patients either withdrew from PD or died.Conclusions Compared with that in 1990 s,the culture positive rate for CAPD related peritonitis in 2000-2005 has been greatly improved.Coagulase-negative staphylococcus is the most common causative pathogen.The mortality and catheter removal rate have been markedly reduced in the last five years.Fungal peritonitis is the most important reason for patients' dropout.

Neospora caninum is the etiologic agent of bovine neosporosis, which affects the reproductive performance of cattle worldwide. The transmembrane protein, NcSRS2, and dense-granule protein, NcGRA7, were identified as protective antigens based on their ability to induce significant protective immune responses in murine neosporosis models. In the current study, NcSRS2 and NcGRA7 genes were spliced by overlap-extension PCR in a recombinant adenovirus termed Ad5-NcSRS2-NcGRA 7, expressing the NcSRS2-NcGRA7 gene, and the efficacy was evaluated in mice. The results showed that the titer of the recombinant adenovirus was 10(9)TCID50/ml. Three weeks post-boost immunization (w.p.b.i.), the IgG antibody titer in sera was as high as 1:4,096. IFN-gamma and IL-4 levels were significantly different from the control group (P<0.01). This research established a solid foundation for the development of a recombinant adenovirus vaccine against bovine N. caninum.

Objective To investigate the effect of family factors on the prognosis of patients with epilepsy and the relationship between family factors and clinical characteristics of epilepsy.Methods Data were collected from 107 patients definitely diagnosed with epilepsy who were treated by antiepileptic drugs for at least two years.All the patients were divided into good or poor prognosis group according to whether achieving at least one year free of seizures.The clinical and family data were colleeted.The questionnaire Family Adaptability and Cohesion Evaluation Scale-Ⅱ-Chinese Version containing 30 items was used for patients and the Epilepsy Knowledge Questionnaire containing 34 questions for primary caregiver.We compared the clinical and family factors between the two groups to identify the predictors of poor control of seizures with univariate and multiple Logistic regression,and observed the relationship between family factors and clinical features such as course,type of seizure,seizure frequency,etc,with Pearson correlation analysis.Results Patients with poor prognosis were more likely to have interictal epileptiform discharges (IEDs),multidrug treatment and pre-treatment seizure frequency of more than once monthly (84.6％ (44/52) vs 50.9 ％ (28/55),x2 =13.797,P =0.000;63.5 ％ (33/52) vs 34.5 ％ (19/55),x2 =8.947,P =0.003;38.5％ (20/52) vs 5.5％ (3/55),x2 =17.257,P =0.000).Family in rural area,unbalanced family type,number of family members were much more in poor prognosis group than in good prognosis group (51.9％ (27/52) vs 25.5 ％ (14/55),x2 =7.923,P =0.005;80.8 ％ (42/52) vs 49.1％ (27/55),x2 =11.712,P=0.000;4.1 ± 1.1 vs 3.6 ±0.8,t=2.631,P=0.010).And average family income,education level of father,the level of epilepsy knowledge of primary caregiver were significantly lower in poor prognosis group than in good prognosis group (19/20/13 vs 11/17/27,x2 =7.198,P =0.027;15/30/7 vs 4/34/17,x2 =10.709,P =0.005;36/11/5 vs 15/25/15,x2 =19.022,P =0.000).Multiple Logistic regression analysis demonstrated that IEDs (OR =12.332,95％ CI 2.756-55.190,P =0.001),pretreatment seizure frequency of more than once monthly (OR =8.401,95％ CI 1.573-44.884,P =0.013)were clinical risk factors of unfavorable prognosis;more family members (OR =3.021,95％ CI 1.554-5.870,P =0.001),poor epilepsy knowledge of primary caregiver (OR =3.392,95％ CI 1.304-8.821,P=0.012) and unbalanced family type (OR=4.794,95％ CI 1.217-18.894,P=0.025) were independent family risk factors of poor prognosis.The level of epilepsy knowledge of primary caregiver was inversely associated with duration (r =-0.237,P =0.014).Conclusions The prognosis of epilepsy is not only affected by clinical factors,but also by family factors.More family members,poor epilepsy knowledge of primary caregiver and unbalanced family type are independent risk factors of unfavorable prognosis.The poorer epilepsy knowledge the primary caregivers have,the longer duration the disease has.

OBJECTIVETo evaluate the efficacy of Bufei Yishen Granule BFYSG) combined with Shufei Tie acupoint sticking therapy on quality of life of patients with stable chronic obstructive pulmonary disease (COPD).

METHODSA multi-center, double-blinded, double-dummy and randomized controlled method was adopted in this trial. A total of 244 patients were randomly assigned to a trial group and a control group according to the random number, each with 122 patients; treatment allocation occurred when the participants met the inclusion criteria and signed the informed consent form. In the trial group, patients were treated with BFYSG combined with "Shufei Tie" acupoint sticking therapy and sustained-release theophylline dummy, and in the control group patients were treated with oral sustained-release theophylline and BFYSG dummy combined with "Shufei Tie" acupoint sticking therapy dummy. The therapeutic course for two groups was 4 months and the follow-up was 6 months. The frequency and duration of acute exacerbation calculated by adding up each frequency and duration of acute exacerbation in treatment and follow-up time respectively, the quality of life measured by the World Health Organization Quality of Life (WHOQOL)-BREF scale and adult COPD quality of life (COPD-QOL) scale were observed.

RESULTSAmong the 244 enrolled patients, 234 were screened for full analysis set (FAS); 221 were screened for per-protocol analysis set (PPS). After 4-month treatment and 6-month follow-up there were differences between the trial group and the control group in frequency of acute exacerbation (FAS: P=0.013; PPS: P=0.046); duration of acute exacerbation (FAS: P=0.005; PPS: P=0.006); scores of physiological, psychological and environment aspects of the WHOQOL-BREF questionnaire (FAS: P=0.002, P=0.006, P=0.000; PPS: P=0.00, P=0.001, P=0.000); scores of daily living ability, social activity, depression symptoms aspects of the COPD-QOL questionnaire (FAS: P=0.000, P=0.000, P=0.006; PPS: P=0.002, P=0.001, P=0.001).

CONCLUSIONBFYSG combined with acupoint sticking therapy could improve the quality of life of patients with stable COPD.
