OBJECTIVESTo study the impact of asymptomatic prostatitis on semen parameters.

METHODBased on the count of WBC in EPS, we assigned 152 patients with asymptomatic (type IV) prostatitis to Groups A (WBC + to + +) and B (WBC + + + to + + + +), and included 68 normal healthy men controls in Group C. All the patients were examined for the volume, pH value and liquefaction time of the semen, sperm concentration, sperm survival rate, grade a sperm percentage, morphologically normal sperm percentage, WBC count, and accompanying inflammatory cytokines.

RESULTSThe semen liquefaction time, grade a sperm percentage and morphologically normal sperm percentage were (24.5 +/- 5.2) min, 20.0 +/- 4.1 and 10.5 +/- 4.8 in Group A, (30.4 +/- 5.0) min, 10.0 +/- 3.8 and 7.5 +/- 4.2 in Group B, and (18.5 +/- 5.3) min, 32.3 +/- 4.5 and 17.8 +/- 3.6 in Group C, with statistically significant differences between A and B (P < 0.01). The pH value, semen volume, sperm survival rate and sperm concentration were 7.6 +/- 0.3, (3.0 +/- 1.1) ml, 56.0 +/- 6.0 and (65.9 +/- 11.3) x 10(6)/ml in Group A, 7.7 +/- 0.3, (2.8 +/- 1.2) ml, 52.3 +/- 6.3 and (62.5 +/- 10.3) x 10(6)/ml in Group B, and 7.5 +/- 0.2, (2.9 +/- 1.2) ml, 62.1.0 +/- 5.3 and (87.7 +/- 10.1) x 10(6)/ml in Group C, with no significant differences among the three groups (P > 0.05). The contents of interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha) in the semen were (58.64 +/- 30.82) pg/ml and (50.57 +/- 27.48) pg/ml in Group B, significantly increased as compared with (17.68 +/- 5.65) pg/ml and (23.50 +/- 4.80) pg/ml in Group C (P < 0.01).

CONCLUSIONAsymptomatic prostatitis effects significant changes in the major parameters of the patient's semen quality.

OBJECTIVETo observe the short term effect of argon plasma coagulation (APC) combined with cryotherapy via bronchoscopy for treatment of severe post-intubation tracheal stenosis in a child.

METHODA 3-year old boy was admitted for cephalothorax abdominal compound trauma and dyspnea, who had severe post-incubation tracheal stenosis. The agreement about the operation risk was signed by the parents. Endotracheal APC procedure was performed with a bronchoscope under general anesthesia. The APC probe was put into the working channel of the bronchoscope. The stenotic lesion was endoscopically visualized and then coagulated by argon plasma. Such coagulation was carried out several times at the stenotic site until it gradually became dilated. The devitalized tissue was mechanically removed with grasping forceps. Thereafter, bronchoscopic cryosurgery was repeatedly performed at the stenotic site. Clinical symptoms, signs and bronchoscopic manifestations were observed right after operation, after 1 day, 10 days, 1 month and 6 months separately.

RESULTTracheal tissue hyperplasia and cyanosis disappeared, laryngeal stridor and dyspnea improved obviously right after the operation. General condition of the patient was well, there was no laryngeal stridor and dyspnea 10 days after operation. The mucosa of the surgical site was smooth and no tracheostenosis was seen under bronchoscope at 1 month and 6 months after the operation.

CONCLUSIONArgon plasma coagulation combined with cryotherapy via bronchoscope is an effective method to treat tracheal stenosis of children, which needs further exploration for the application.
