Objective To compare the propagation speed and physical parameters between underwater blast wave and air blast wave. Methods The physical parameters of blast wave were measured by PCB pressure transducers (USA) during underwater and air explosions of 200g, 500g and 1000g TNT respectively. Consequently, the propagation speed, peak overpressure value, positive duration and impulse of blast wave were analyzed. Results Underwater blast wave was characterized by high propagation speed, high peak overpressure value, great impulse, however, short duration. Compared with air blast wave, the propagation speed of underwater blast wave was 3.70-4.30 times higher than that of air blast wave, the peak overpressure value was 227.15-247.86 times higher, and the impulse was 8.48-11.80 times greater than that of air blast wave. Conclusion Underwater blast wave propagates faster than that air blast wave. Meanwhile, it also peoduces higher peak overpressure value and impulse. This result is helpful for the evaluation of injury severity and treatment of underwater blast injury.

Objective To investigate effect of urinary conditions and lower urinary tract symptoms (LUTS) in patients before and after the reconstructive pelvic surgery (RPS) for pelvic organ prolapse (POP) as well as effect of urinary conditions and LUTS by tension-free vaginal tape-obturator (TVT-O).Methods From Jan. 2007 to Dec. 2009, 213 patients with POP underwent RPS, the factors on preoperative, postoperative urinary conditions and qualities of life and postoperative urinary incontinence were studied prospectively. Results Totally 193 patients who was followed up for more than 3 months after surgery attend questionnaires, and 165 preoperative patients of 193 (85.5%) had LUTS, 105 postoperative patients of 193 (54.4%) had LUTS, which reached statistical difference (P <0. 01 ). The rate of LUTS before and after operation: urinary frequency ( 57.0% and 25.9% ), urinary urgency ( 51.8% and 28.0% ), urinary leakage due to cough ( 50. 3% and 15.0% ), dropping urinary leakage ( 44. 6% and 14. 5% ), dysuria (34. 7% and 23.3% ), vesicaltenesmus (49.2% and 19. 7% ) and hand assist urination (31.1% and 2.6% ). The incidence of LUTS after surgery is much lower than that of pre-operation ( P <0. 05 ). POP patients with stress urinary incontinence ( SUI ) before the operation, surgery without TVT-O simultaneously are the risk factors of unimproved symptom ( OR = 4. 933, 95% CI: 1. 353 - 17. 990, P=0. 016). Conclusions RPS have alleviated LUTS in patients with POP. RPS with TVT-O are more effective than traditional RPS in treatment of the urinary incontinence if the POP patient with SUI or occult SUI.

Objective To study the value and limitation of CT in the damage to multiple organs in children with Langerhans cell histiocytosis (LCH). Methods Analysis of CT manifestations was performed in 13 cases of LCH proved by clinical features, laboratory data, and pathologic changes. Localized LCH was found in 4 cases, and disseminated LCH in 9 cases. All cases were examined by plain scan in craniocerebral, chest, liver, and spleen, and four cases by contrast-enhanced CT scan. Results The male outnumbered female in this group. Cranial bones were involved in the sequence of temporal bone(8 cases), parietal bone (3 cases), occipital bone (2 cases), and frontal bone (1 case). CT findings were very sensitive in showing the early destructions of the bones. The characteristic manifestation on CT was multiple lytic lesions of the flat bones at any sites, without reactive sclerosis and soft tissue mass accompanied with the bony lesion. Imaging findings presented later than the clinical manifestations for LCH involving the hypothalamus/pituitary axis. Involvement of the lung at various stages by LCH could be demonstrated by CT scan. Conclusion Imaging manifestations had no characteristics in LCH involvement. The sites of predilection and related CT manifestations could be suggestive of the diagnosis. In addition, CT findings can be helpful in the classification and evaluation of the therapy and prognosis in LCH.
