Objective To study the safety and efficacy of target-controlled infusion (TCI) sedation with low dose ketamine and propofol during rigid cystoscopy in elderly male patients. Methods Forty-five elderly male patients with I - III grade of the American Society of Anesthesiologists (ASA)rigid cystoscopy examination were divided into 3 groups randomly: group A, 2% lydocaine gel was filled in urethra, n=15; group B, 2% lydocaine gel filled with propofol TCI sedation, n=15; group C, 2% lydocaine gel filled with combined ketamine and propofol TCI sedation, n= 15. The mean artery pressure (MAP), heart rate(HR), pulse oxygen saturation (SPO2)were measured at 5 time points; preoperation, during local anesthesia, inserting the scope, during testing and the end of testing. The concentration of effect room, wake time when alertness and calm grading (OAA/S)was 3 scores in B and C groups and visual analogue scale( VAS) score of pain after operation were detected. Results The MAP and HR at the time point of inserting the scope in group A had significant difference,compared with preoperation(P0. 05) . In group A, 10 cases pain VAS score were light pain, 4 moderate and 1 severe. In group B and C,no pain and no memory of the operation were reported. Conclusions TCI sedation with low dose of ketamine and propofol in elderly male patients under rigid cystoscope has good effects on sedation, analgesia and anterograde amnesia. The hemodynamics is stable and wake time is short.

Objective: To evaluate the quality status of recombinant human interferon α2a injections and find out some quality problems. Methods:The statutory testing methods combining with the exploratory studies were used to examine the samples, and the quality status of recombinant human interferon α2a injections was evaluated by statistical analysis of the results. Results: All 28 bat-ches of the injections were qualified using the statutory testing methods. The exploratory studies showed that if the specific activity was determined, the qualified rate was only 87. 0%. All 7 batches of drug substances were qualified using the statutory testing methods. The exploratory studies showed that if the related protein was determined, the qualified rate was 57. 1%. Conclusion:At present the quality of recombinant human interferonα2a injections is generally good. The current standards are feasible;however, improvement is still needed. Specific activity determination should be supplemented the standards for drug products and related protein determination should be supplemented the standards of drug substances.

Objective To evaluate the clinical and pathological factors that may influence serum prostate specific antigen(PSA)level in patients with benign prostatic hyperplasia(BPH).Methods A total of 561 cases of BPH diagnosed by pathological examination following operation were analyzed retrospec- tively.The patients'mean age was(68.3?6.3)years.The International Prostate Symptom Score(IPSS)was 21.1?7.4;the quality of life(QOL)was 4.5?0.8;Qmax was(7.3?3.3)ml/s;prostate volume(PV) was(69.8?36.8)ml;andpost-void residue(PVR)was(81.9?105.8)ml.Results Of 561 cases,223 cases(39.8%)had serum PSA level at 4-10 ng/ml,and 91 cases(16.2%),over 10 ng/ml.The level of serum PSA was not significantly associated with age,IPSS,QOL,Qmax and PVR(r=0.08,0.03,0.06,0.04 and 0.09,respectively;P＞0.05),but significantly associated with prostate volume of BPH(r=0.42,P＜0.01).The level of serum PSA was significantly elevated in BPH patients with enlarged prostate volume (F=93.45,P＜0.05)and the history of acute urinary retention(x~2= 59.1,P＜0.01).Additionally,a significantly increased PSA level was noted in tissue specimens with glandular hyperplasia(x~2=16.14,P＜0.01)or necrotic loci in BPH patients(x~2=36.06,P＜0.01).Conclusions An elevated serum PSA level was observed in more than 50% of BPH patients undergoing surgical resection.Enlarged prostate volume,the history of acute urinary,retention,and tissue specimens with glandular hyperplasia or necrotic foci are considered to be the main causes leading to elevated PSA level in BPH patients.

Objective To observe the position and mobility of the tape after tension-free vaginal tape-obturator(TVT-O) surgery using transperineal two and three dimensional ultrasonography in patients with stress urinary incontinence.Methods A total of 32 patients with stress urinary incontinence who had TVT-O surgery and cured were enrolled.Transperineal two and three dimensional ultrasonography were performed after operation 3 months later.Both the position,morphology and mobility of the tape at rest and during Valsalva menuaver were observed.Results The tapes were mainly located in the 1/3 connection of the middle and distal urethra.The length of the urethra and the length of the urethra between the bladder neck and the proximal tape at valsalva menuaver were longer than those at rest.The tapes moved front-down at valsalva manuaver according to the mean distance between the tape and the symphysis pubis.The angles of the tapes were smaller at valsalva manuaver without significant difference.Conclusion It is useful to observe the position,morphology and mobility of the tape using transperineal two and three dimensional ultrasonography.The changes of the position and morphology of the tapes at valsalva menuaver were not significant.But the tapes can strengthen the urine control in the middle of urethra.

Objective To find out the relation between element (non-iodized salt and iodized salt that below standard) and epidemic strength of iodine deficiency disorders and level of iodine, in order to find out the factors affecting the result of using iodized salt in controlling of this disorders. Methods Retrospective analyses was used in the study. Six counties were selected randomly from Zhangjiakou every year from 2000 to 2008, and these counties were randomly divided into non-iodized salt group (the ratio of non-iodized salt > 5%), iodized salt below standard group (the ratio of qualified iodized salt < 95%) and control group (the ratio of using qualified iodized salt > 95%). The indexes from different groups were compared as well as the ratio of large thyroid syndrome in children aged 8-10 years and the level of iodine in urine. Results The number of iodized salt monitored were 12 468 units from 2000 to 2008. We examined 5655 children's thyroid and collected 4404 urine samples. The median was 30.1 mg/kg for the average of iodized salt and 7.30% (232/3180) for ratio of non-iodized salt in noniodized salt group, while 30.9 mg/kg and 93.10%(3776/4056) in iodized salt below standard group, and 32.0 mg/kg and 99.27%(5194/5232) in control group. Compared the median of the three groups[5.31%(78/1468) ,4.84% (92/1902) ,2.06% (47/2285)], we observed significant difference (χ2 = 72.07, P < 0.05), especially the ratio of large thyroid in non-iodized salt group which was apparently higher than that of the control group (χ2 = 8.70, P < 0.017). However there was no significant difference between iodized salt below standard group and non-iodized salt group(χ2 = 6.83, P > 0.017) and control group(χ2 = 5.65, P > 0.017). The median of urinary iodine was 188.20 μg/L in non-iodized salt group, 219.62 μg/L in iodized salt below standard group and 262.39 μg/L in control group, indicated that the index in control group was higher than that of others. Conclusion Both of non-iodized salt and iodized salt below standard have effect on prevalence of child iodine deficiency disorders, especially the non-iodized salt.
