OBJECTIVETo study the application of Bayes probability model in differentiating yin and yang jaundice syndromes in neonates.

METHODSTotally 107 jaundice neonates who admitted to hospital within 10 days after birth were assigned to two groups according to syndrome differentiation, 68 in the yang jaundice syndrome group and 39 in the yin jaundice syndrome group. Data collected for neonates were factors related to jaundice before, during and after birth. Blood routines, liver and renal functions, and myocardial enzymes were tested on the admission day or the next day. Logistic regression model and Bayes discriminating analysis were used to screen factors important for yin and yang jaundice syndrome differentiation. Finally, Bayes probability model for yin and yang jaundice syndromes was established and assessed.

RESULTSFactors important for yin and yang jaundice syndrome differentiation screened by Logistic regression model and Bayes discriminating analysis included mothers' age, mother with gestational diabetes mellitus (GDM), gestational age, asphyxia, or ABO hemolytic diseases, red blood cell distribution width (RDW-SD), platelet-large cell ratio (P-LCR), serum direct bilirubin (DBIL), alkaline phosphatase (ALP), cholinesterase (CHE). Bayes discriminating analysis was performed by SPSS to obtain Bayes discriminant function coefficient. Bayes discriminant function was established according to discriminant function coefficients. Yang jaundice syndrome: y1= -21. 701 +2. 589 x mother's age + 1. 037 x GDM-17. 175 x asphyxia + 13. 876 x gestational age + 6. 303 x ABO hemolytic disease + 2.116 x RDW-SD + 0. 831 x DBIL + 0. 012 x ALP + 1. 697 x LCR + 0. 001 x CHE; Yin jaundice syndrome: y2= -33. 511 + 2.991 x mother's age + 3.960 x GDM-12. 877 x asphyxia + 11. 848 x gestational age + 1. 820 x ABO hemolytic disease +2. 231 x RDW-SD +0. 999 x DBIL +0. 023 x ALP +1. 916 x LCR +0. 002 x CHE. Bayes discriminant function was hypothesis tested and got Wilks' λ =0. 393 (P =0. 000). So Bayes discriminant function was proved to be with statistical difference. To check Bayes probability model in discriminating yin and yang jaundice syndromes, coincidence rates for yin and yang jaundice syndromes were both 90% plus.

CONCLUSIONYin and yang jaundice syndromes in neonates could be accurately judged by Bayesian discriminating functions.

OBJECTIVETo investigate the effectiveness of surgical strategies for Shang Ring circumcision in the treatment of short frenulum praeputii in patients with redundant prepuce or phimosis.

METHODSTotally, 130 cases of short frenulum praeputii with redundant prepuce or phimosis were randomly assigned to an experimental group and a control group of equal number to receive Shang Ring circumcision, the former by transverse incision in the distal penis foreskin and pull-up of the interior board, and the latter by conventional transverse incision and longitudinal suture of the frenulum praeputii. Comparisons were made between the two groups in the surgical duration, intraoperative blood loss, 24 h postoperative pain visual analog score (VAS), postoperative complications, satisfaction with the penile appearance, and the quality of sexual life.

RESULTSThe surgical duration, intraoperative blood loss, 24 h postoperative VAS, postoperative sexual satisfaction, and satisfaction with penile appearance were (4.60 +/- 1.20) min, (2.61 +/- 1.81) ml, 1.73 +/- 0.76, 98.5%, and 98.5%, respectively, in the experimental group, as compared with (21.60 +/- 6.30) min, (11.10 +/- 3.40) ml, 5.37 +/- 1.84, 70.3% and 69.8% in the control, with statistically significant differences between the two groups (P < 0.05). The incidence rates of such major complications as wound dehiscence, infection, and moderate to severe edema were 1.5% (1/65), 3.1% (2/65), and 4.6% (3/65), respectively, in the experimental group in comparison with 12.3% (8/65), 15.3% (10/65), and 30.7% (20/65) in the control, with statistically significant differences between the two groups (P < 0.05). None of patients had any serious complications.

CONCLUSIONShang Ring circumcision by transverse incision in the distal penis foreskin and pull-up of the interior board, with its advantages of shorter operation time, less blood loss, mild pain, fewer complications, and higher satisfaction and acceptance of the patients, can be used as an safe and effective approach to the treatment of short frenulum praeputii.

OBJECTIVETo investigate the clinical value of the mass screening by analyzing the features of prostate cancer between mass screening patients and clinical patients.

METHODSFrom January 2000 to January 2008, 441 cases of prostate cancer (including 122 patients from clinical diagnosis and 319 patients from mass screening 23 183 men who were more than 50 years old) were analyzed from age, digital rectal examination (DRE), serum prostate specific antigen (PSA) levels and range, the Gleason's score and grade, clinical staging and therapy.

RESULTS42.0% of mass screening patients were inspected by DRE, it was lower than that (79.5%) in the clinical patients. The percent of patients with serum PSA levels of less than 10.0 microg/L in mass screening group was higher than in clinical group, while the percent of patients with serum PSA levels of more than 20.0 microg/L in mass screening group was lower than in clinical group. The percent of moderately differentiated degree of prostate cancer in mass screening group was higher than in clinical group, but it was on the contrary for poorly differentiated degree of prostate cancer. The percent of T1-2 prostate cancers in mass screening group was 56.1%, which was higher than 25.4% in clinical group. While, the percent of T3-4 tumors in mass screening group was lower than in clinical group. The percent of men undergoing radical prostatectomy in mass screening group was 18.2%, which was higher than 9.8% in clinical group. The percent of men of locally advanced and far metastasis in mass screening group was 26.0%, while was lower than 46.0% in clinical group.
