ABSTRACT
Objective To explore the feasibility of tubeless 2 μm laser vaporesection in treating pediatric ureter cysts by ureteroscopy.MethodsClinical data of 33 ureter cysts patients who received tubeless 2 μm laser vaporesections by ureteroscopy were reviewed. The median age of patients was 4 years with a range from 1 to 7 years. The operations were carried out by RevoLix 2 μm laser through ureteroscopy without ureter stents and catheters indwelling.ResultsAll operations were successfully performed. And no serious complications occurred after the operations.ConclusionsTubeless transurethral 2 μm laser treatment by ureteroscopy was a superior micro-invasive surgery method for pediatrics with ureter cysts, with advantages of little blood loss, high safety, convenient operation and infrequent complications.
ABSTRACT
Objective To investigate the clinical efficacy of RevoLix 2 μm continuous wave laser treatment on bladder neck contracture after benign prostatic hyperplasia operation. Methods A total of 21 cases were enrolled in current research and they all accepted 2 μm continuous wave laser treatment of bladder neck contracture after benign prostatic hyperplasia operation in the 252th Hospital of the Chinese People's Liberation Army. The clinical efficacy was recorded. Results The operation of the 2 μm continuous wave laser vaporesections were successfully performed on 21 cases. The maximum urine flow rate was increased from(6. 86 ± 1. 97)ml/ s to(16. 31 ± 1. 61)ml/ s,and the difference was significant(t = 15. 49,P < 0. 01). After 3 to 23 months(median 14 months)follow-up,20 cases were cured and 1 case was combined with bladder residual urine 110 ml. Conclusion The therapy of 2 μm continuous wave laser is a superior micro-invasive surgery method for patients with Bladder neck contracture,which shows little blood loss,high level safety,convenient operation and infrequent complications.
ABSTRACT
<p><b>OBJECTIVE</b>This study detects the expression of secreted frizzled-related protein 1 (SFRP1) in healthy patients and patients with chronic periodontitis (CP) and explores the relationship between SFRP1 and the occurrence and development of CP.</p><p><b>METHODS</b>First, 28 patients forming the CP group were further divided into mild, moderate, and severe CP subgroups according to clinical attachment loss (CAL) data. Ten healthy volunteers were recruited in the control group. Gingival crevicular fluid (GCF) was collected from all of the patients, and the concentration of SFRP1 in the GCF samples was detected using enzyme-linked immunosorbent assay. Next, gingival lesions were obtained from 22 patients in the CP group and healthy gingival tissues were obtained from the 10 healthy patients in the control group. Immunohistochemical analysis for SFRP1 was used to analyze the correlation between the expression of SFRP1 and the severity of CP based on staining intensities.</p><p><b>RESULTS</b>The concentration of SFRP1 in GCF samples taken from of the CP group (281.07 ng x L(-1) +/- 33.37 ng x L(-1)) was significantly higher than that in samples taken from the control group (245.30 ng x L(-1) +/- 35.69 ng x L(-1)) (P < 0.05). A significant positive correlation was observed between the concentration of SFRP1 in GCF and CAL (r = 0.651, P < 0.001). Furthermore, the SFRP1 scores in the CP groups (4.500 +/- 0.913) were significantly higher than those in the control group (2.800 +/- 1.135) (P < 0.001). SFRP1 scores did not vary significantly among the CP subgroups (P > 0.05).</p><p><b>CONCLUSION</b>SFRP1 expression in the CP groups was significantly higher than that in the control group. Thus, SFRP1 may play a significant role in the development of CP.</p>

Objective To provide evidence for the pharmacological action of blood-activating and blood-stasis-dissipating medicines by studying the influence of Zhenxintong Oral Liquid (ZOL) on thrombus-associated marker levels in coronary heart disease with blood-stasis syndrome. Methods Forty male Wistar rats were randomly allocated to 5 groups: normal group,model group,large-dose ZOL group,small-dose ZOL group and Compound Danshen Drip Pill(CDDP) control group. Blood-stasis models were established by peritoneal injection of dexamethasone (0.25mg?kg-1?d-1). After 8 days of treatment,levels of activated partial thromboplastin time (APTT),antithrombin -Ⅲ(AT-Ⅲ),tissue-type plasminogen activator (t-PA) and tissue-type plasminogen activator inhibitor (PAI) in blood from abdominal aorta were determined. Results AT-Ⅲlevel in the two ZOL groups and in CDDP control group was significantly higher than that in model group(P 0.05). t-PA level was higher and PAI level was lower in large-dose ZOL group than that in CDDP control group (P
