OBJECTIVETo develop the method and investigate the value of the application of multislice helical computed tomography (CT) in the maxillofacial distraction osteogenesis.
METHODSTwelve cases of maxillofacial distraction osteogenesis (3 in zygoma, 2 in maxilla, and 7 in mandible) were scanned by the multislice helical CT, then the reconstruction of three dimensional and fault image and the relative measurement were carried out to study the effect of distraction and osteogenesis.
RESULTSThe three dimensional image provided clear and high resolution stereoscopic view that the effect of distraction osteogenesis could be evaluated easily and exactly. The fault image could be set up in private computer by Mimics and the measurements, such as distance, thickness and density, could be performed as expected. The effect of 12 cases was satisfied, and the average distracted distance was 16.73 mm.
CONCLUSIONBasing on multislice helical CT scanning, the high resolution image reconstruction and relative measurement data could be obtained which could meet the need of clear and direct observation. Its application in the maxillofacial distraction osteogenesis is expecting and promising.

AIMTo probe into the affection and significance of NO on the expression of P-selectin in renal injury following hind limb ischemia/reperfusion in rats.
METHODSIn accordance with the conventional approaches of our department, the model rats were prepared after they were made to undergo 4 hours or ischemia followed by 4 hours of reperfusion of hind limbs. The Wistar rats were divided into four groups randomly: Control group, LI/R group, L-Arg group and L-NAME group. And then in those four groups of Wistar rats, a series of values of measurement were determined such as: Plasma concentrations of nitric oxide (NO), blood urea nitrogen (BUN) and creatinine (Cr). Furthermore, biochemically there came to the assessment of the values including myeloperoxidase (MPO), NO, total nitric oxide synthase (tNOS), inducible NOS (iNOS) and constitutive NOS (cNOS) of renal tissue in different groups. By the methods of electrophoresis and biochemistry, the urine protein was mensurated. The immunohistochemical method was used to detect the expression of P-selectin protein. The morphologic changes were observed with a microscope.
RESULTSAfter hind limbs had suffered from ischemia/reperfusion for 4 hours, there was the occurrence of a series of results such as in the following which were based on the comparison between plasm of LI/R group and control group. The values of NO, BUN and Cr increased significantly, and the trend of indexes such as NO in renal tissue was similar to that in plasma. The values of MPO, tNOS and iNOS in renal tissue all increased significantly after reperfusion, while cNOS decreased distinctly. The urine protein appeared, especially large molecular weight protein. Renal pathology revealed that after LI/R there were edema and infiltration of polymorphonuclear neutrophil (PMN). Immunohistochemically, the expression of P-selectin was upregulated significantly. Compared with LI/R rats, all injury changes were alleviated in L-Arg group. Morphologic changes were mild. Both the content of urine protein and the percentage of apoptosis cell decreased. The expression of P-selectin was downregulated. In L-NAME group, all injury changes got worse. Immunohistochemical results showed strong positive staining of P-selectin.
CONCLUSIONThe renal injury after LI/R may relate to the strong expression of P-selectin. NO may have protective affection by decreasing the expression of P-selectin and alleviating the adhesion, aggregation and infiltration of neutrophils.

OBJECTIVESThe National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) was used to determine the chronic prostatitis syndrome in young men (from 20 to 48 years old) of clinical validity.
METHODS227 patients with chronic prostatitis syndrome (CPS)/chronic pelvic pain syndrome and 32 patients with BPH were randomized to study using NIH-CPSI.
RESULTS1. The main manifestations of CPS patients were pain or uncomfort. Those were more common in CPS than BPH. 2. 79.30% CPS patients had a sensation of not emptying bladder completely after finished urinating, 44.93% patients had to urinate again less than two hours after finished urinating. 3. 51.51% patients with CPS have more effect on work, 90.31% patients on free life, and 68.72% patients on quality of life than BPH.
CONCLUSIONSAccording NIH-CPSI, the main manifestations of CPS are pain or uncomfort. CPS patients have more effect on work and quality of life.

Objective:
To determine the risk factors for occult endometrial atypia and malignancy in patients diagnosed with non-atypical endometrial hyperplasia (NEH) on endometrial biopsy.
Methods:
All new cases of NEH diagnosed between April 2015 and March 2016 at KK Women’s and Children’s Hospital, who underwent hysterectomy as first-line treatment, were included in the study. Patients with a history of endometrial hyperplasia or malignancy were excluded from the study. Patient demographics (e.g., age, parity, body mass index [BMI]), medical history, and clinical presentation were obtained for analysis.
Results:
In total, 262 patients were diagnosed with NEH, of which 18.3% (n=48) underwent hysterectomy as first-line management. The average time to surgery was 77.0±35.7 days. All cases were diagnosed by dilation and curettage, and hysteroscopy. The mean age was 51 years, and the mean BMI was 26.9±5.8 kg/m2. Histology from the hysterectomy specimen showed 9 (18.8%) patients with atypical hyperplasia and 2 (4.2%) with grade 1, stage 1A endometrioid adenocarcinoma. Patients with higher grade final pathology had significantly lower median parity (1 vs. 2, P=0.039), higher mean BMI (30.1±6.5 vs. 25.9±5.3 kg/m2, P=0.033), and BMI ≥30 kg/m2 (54.5% vs. 13.5%, P=0.008, odds ratio 7.68), compared to patients whose final histology showed NEH or no residual hyperplasia.
Conclusion
Occult endometrial atypia and malignancy were found in 18.8% and 4.2% of patients with an initial diagnosis of NEH, respectively. High BMI and low parity were identified as significant risk factors for high-grade endometrial lesions in patients with NEH.

Objective To examine the effect of estradiol (E2) treatment on ovariectomy (OVX) induced depressive-like behavior and possible mechanism by measuring inflammatory biomarkers levels oi interleukin-6 (IL-6) and tumor necrosis tactor-(x (TNF-ot) and brain-derived neurotrophic factor (BDNF) expression in amygdaia nucleus. Methods Thirty nine healthy aduit 缶male SD rats were randomly divided into three groups : sham operation group (SO), ovariectomized group (OVX) and ovariectomized estradiol treatment group (OVX + E2). After 6 weeks of E2 treatment, depressive like behavior was evaluated by opening field test (OFT) and sugar water preference test (SPT). The levels of inflammatory factors IL-6 and TNF-a in amygdala were measured by ELESA, and the expression of BDNF in rat amygdala was detected by immunohistochemical staining. Results The result of the SPT showed that OVX significantly decreased the sugar intake and sugar preference rate of rats, and E2 treatment significantly increased sugar water intake and sugar water preference rate of rats. The result of the OFT showed that OVX significantly decreased the numbers of crossing and rearing of rats, and reduced the time spent in the centre ; E2 treatment significantly increased the numbers of crossing and rearing of rats, and prolonged the time spent in the centre. ELESA and immunohistochemical analysis found the levels of IL-6 and TNF-a in amygdala increased significantly, while the average absorbance (AA) of BDNF in the amygdala reduced significantly (P<0.01 respectively) of rats in OVX group when compared with the SO group. And the levels of IL-6 and TNF-a in amygdala decreased significantly (P<0.01 respectively), while the A4 of BDNF increased significantly (P< 0.05) in the amygdala of rats in the OVX+EX group when compared with the OVX group. The difference was statistically significant. Conclusion E2 treatment improved depression-like behavior of OVX rats is partly due to increased antiinflammatory and activated the BDNF expression in amygdaloid nucleus, thus enhancing the neuroprotective effect of OVX rats.
