Objective To clarify the features and early diagnosis of the traumatic diaphragmatocele associated with pelvic fracture. Methods The clinical materials of 486 multiple injuried patients with pelvic fractures as main trauma were retrospectively analysed. The pathogenesis, clinical manifestation and reasons for misdiagnosis in 9 cases of traumatic diaphragmatocele were analysed. Results In this series, the incidence of the traumatic diaphragmatocele was 1.9%(9 of 486). Because of under recognition of this associated injury, 7 in 9 cases of traumatic diaphagmatocele were misdiagnosed or undiagnosed. The incidence of misdiagnosis was 77.8% in this series. Conclusion The main reason for the occurrence of diaphragmatocele was the rapid increase of the intra abdominal pressure which resulted in rupture of the weak area of the diaphragm. Type B1 pelvic fracture can cause traumatic diaphragmatocele easily. The symptoms of the diaphragm hernia are easily overlooked when the trauma is serious or the patient is in shock. Because the early symptoms are not often evident and typical, the doctor can not notice it thoroughly. The main reason for misdiagnosis of the diaphragm hernia is the poor clinical presentation and sign of the diaphragmtocele which initially is very similar to that of the thoraco abdominal injury. In the case with chest and abdominal symptoms concomitant with pelvic fracture should be observed carefully and the chest and abdominal radiographs should be taken as soon as possible. Closed attention should be paid to diaphragmatocele when treating a pelvic fracture in consideration of 7 out of 9 patients being misdiagnosed in this series.

OBJECTIVETo investigate thirdhand smoke (THS) pollution in certain places of Nanjing, as well as to analyze its distribution characteristics.

METHODSFrom March to May, 2014, we selected 3 types of places (residencies, public places and transportation vehicles) that were close to people's living in Jianye,Yuhua,Jiangning,Xuanwu,Gulou and Pukou districts of Nanjing city.For each of the above 3 types of places, 2-3 smoking and non-smoking (smoking ban) locations were investigated, totally 51 locations, 9-10 samples were collected each location, totally 477 samples. The surface wipe sampling method in conjunction with liquid chromatography-tandem mass spectrometry (LC-MS/MS) was utilized to quantify the levels of nicotine that served as the tracer of THS pollution.One-way ANOVA and t-tests were employed to compare the levels of nicotine collected at different places and locations.

RESULTSTotally 477 samples were collected in this study, of which 27.0% was from residencies (129/477), 61.0% (291/477) from public places and 11.9% (57/477) from transportations. The levels of indoor surface nicotine in smoking residences, public places and transportations were (214 ± 55),(1 408 ± 177) and (1 511 ± 785) µg/m(2), respectively, which were all higher than those in the corresponding non-smoking places ((23 ± 9),(62 ± 11), and (46 ± 15) µg/m(2); t values were 13.79, 13.15, 3.45, respectively. P values were <0.001, <0.001 and 0.006, respectively).In the smoking places, the levels of surface nicotine on walls, desks, sofas, cabinets, door backsides and air conditioning openings were (171 ± 62),(232 ± 38),(373 ± 151),(903 ± 239), (978 ± 212), (1 721 ± 517) µg/m(2) (F = 7.06, P = 0.009).In the smoking condition, the levels of surface nicotine collected from public places were higher (F = 9.25, P = 0.024), while under non-smoking (smoking ban) conditions, the levels of surface nicotine collected from residences were lower (F = 7.88, P < 0.001).

CONCLUSIONTHS pollution was widespread in public places, residences and transportations in Nanjing city, which was more serious in the smoking environments than non-smoking (smoking ban) environments; the contamination was less serious in non-smoking (smoking ban) private residences; in the smoking condition, the levels of surface nicotine were relatively high at locations close to air conditioning openings, door backsides and cabinets.
