Objective To study the correlation of personality characteristics and plasma cortisol levels in the patients with generalized anxiety disorder.Methods According to Diagnostic and Statistical Manual of Mental Disorders (DSM-Ⅳ), 38 patients with generalized anxiety disorder and 39 normal controls were assessed with Hamilton anxiety scale (HAMA) , generalized anxiety disorder scale (GAD-7) , penn state worry questionnaire (PSWQ) , symptom checklist-90(SCL-90) and eysenck personality questionnaire (EPQ).Electrochemiluminescence was used to test plasma cortisol concentration.Results The EPQ-N score in the patients was significantly higher than that in normal controls(t=14.307, P＜0.01).Furthermore,N score in the patients showed a significantly positive correlation with HAMA total score, SCL-90 total score, somatization score, interpersonal sensitivity score, depression score and anxiety score (r=0.492-0.977, P＜0.01).Plasma cortisol levels in patients with generalized anxiety disorder((668.50±60.22) nmol/L) were significantly higher than those ((345.35±58.91) nmol/L) in normal controls (t=23.802, P＜0.01).Plasma cortisol concentrations displayed a significantly positive correlation with N score, GAD-7, PSWQ, HAMA total score, SCL-90 total score, somatization score, interpersonal sensitivity score, depression score, and anxiety score (r =0.501-0.995, P＜ 0.01).Conclusion Plasma cortisol levels in the patients with generalized anxiety disorder are higher than those in normal controls.Plasma cortisol levels are related to the mental health.Patients with generalized anxiety disorder tend to be neuroticism.

Objective To evaluate the effect of the urinary reservoir constructed with ileocecum-appendix in the elderly with bladder cancer. Methods From March 2002 to June 2008, 12 cases were treated using ileocecum-appendix as the reservoir after radical cystectomy. They all received the imaging urodynamics examination and were followed up for 1 year. Results The 11 of 12 patients had urinary continence completely. Only 1 case had incontinence and 3 cases had incontinentia urinae at night. Times of uresis were 8-10/day and 3-5/night within 3 months after surgery, and 4-6/day and 0-2/night 6 months after surgery. The urinary output was 150-350 ml/time. Urodynamics showed that mean urinary flow rate was 10.5 ml/s, mean initial bladder pressure was 27 cm H2O, the maximum filling pressure was 35 cm H2O. The average reservoir capacity was 152 ml and 420 ml, respectively. The out let pressure of posterior urethra was 52 cm H2O. The volume of residual urine was 0-65 ml. No evidence of ureteral reflux occurred, no hyperchloremic acidosis was observed. Conclusions Orthotopic bladder reconstruction is considered as an ideal form of urinary diversion characterized by low pressure, larger capacity and continence.

Refractory ulcer is a commonly seen disease clinically. We believe the therapeutic strategies for refractory ulcer should include changing life style, standardizing medication, tracing observation, and rechecking in regularity. Traditional Chinese medicine combined with western medicine can be used for the treatment. When the therapeutic effect is not good, diagnosis and therapeutic methods need to be re-judged.Local therapy and operation can be performed if necessary.

Objective To evaluate stone retention time coefficient (RTC) times stone size value (RTC × S) as the indication of extracorporeal shockwave lithotripsy (ESWL) efficacy in the treatment of upper ureteral calculi.Methods From January 2009 to May 2011,180 consecutive patients including 109males and 71 females who underwent ESWL for a single radiopaque upper ureteral stone with the mean stone size (0.9 ± 0.2) cm and the mean stone retention time (12.6 ± 9.7) d were retrospectively analyzed.The mean patient age was 39 years (range from 21 to 65 years).The base of RTC was set as 1 and each 0.1 was added on it if the stone stayed one more week in upper ureter.Patients were classified into 2 groups by stone size.105 patients were in group ＜ 1 cm and 75 patients were in group≥ 1 cm.According to RTC × S value,79 patients were in group ＜ 1 and 101 patients were in group≥ 1.Stone-free rate between these two groups in the same grouping indication and between two matched groups in the different grouping indication were compared respectively.The chi-square test compared categorical variables between the two groups and all statistical analyses were 2-sided with P ＜ 0.05 defined as statistically significant.Results The overall stone-free rate of group ＜ 1 cm was significantly higher than that of group≥ 1 cm (81.9％ vs.68.0％,P ＜0.05).The overall stone-free rate of group RTC × S value ＜ 1 was significantly higher than that of group RTC × S value ≥1 (96.2 ％ vs.60.4％,P ＜ 0.05).Comparison between two matched groups showed that the stone-free rate of group RTC S value ＜ 1 was significantly higher than that of group ＜ 1 cm (96.2％ vs.81.9 ％,P＜0.05),but group RTC×Svalue≥1 was comparable to group≥l cm (60.4％ vs.68.0％,P ＞ 0.05).26 patients with ＜ 1 cm stones were enrolled in group ≥ 1 for long stone retention time and larger RTC × S value.The overall stone-free rate of them was 38.5％ (10/26) which was significantly lower than that of group≥ 1 cm (P ＜ 0.05).Conclusions The stone retention time is an important factor in efficacy of ESWL for upper ureteral calculi.Use RTC × S as a new indication of ESWL,not only the stone size but stone retention time is taken into account as well.ESWL is highly efficacious in patients with RTC × S values ＜ 1.

OBJECTIVETo explore the correlation between the content of lecithin mass and white blood cells (WBC) of the expressed prostatic secretion (EPS) and the concentration of serum PSA in patients with prostatitis, and to study the difference in serum PSA concentration between patients with bacterial prostatitis and those with nonbacterial prostatitis.

METHODSThe serum PSA concentration in 62 patients with prostatitis and 22 controls were measured with ELISA method. The correlation between the content of lecithin mass and WBC of the EPS and the elevation of serum PSA was analyzed. And the serum PSA concentration of bacterial prostatitis (9 patients) and that of nonbacterial inflammatory prostatitis (53 patients) were compared.

RESULTSThe mean concentrations of serum PSA in the prostatitis and the control groups were (1.79 +/- 0.68) microg/L and (0.63 +/- 0.29) microg/L, respectively. The difference of the serum PSA concentration was significant between the prostatitis and the control groups (P < 0.001) as well as between the groups with higher and lower WBC contents in EPS (P < 0.05), but not between the groups with higher (27 patients) and lower (35 patients) lecithin mass contents in EPS (P > 0.05), nor between the groups of bacterial prostatitis and nonbacterial prostatitis (P > 0.05).

CONCLUSIONProstatitis may cause the elevation of serum PSA concentration. The elevated serum PSA correlates with the content of white blood cells in EPS, but not with the content of lecithin mass in EPS, nor with the type of prostatitis, either bacterial or nonbacterial.
