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.

AimTo investigate the protective effect of nerve growth factor (NGF) from the Chinese cobra venom on spinal neurons after sciatic nerve lesion. Methods Fourty Wistar rats were divided into 2 groups each containing 20 animals. After surgical crush lesion on the bilateral sciatic nerve, the rats were injected NGF into the target muscle every day. On the d 5 and d 10 after operation, enzyme histochemistry technique was used to show acetycholinesterase(AchE) activity of the motoneurons in L5~S2 spinal cord anterior hornandfluorideresistantacidphophatase (FRAP) activity of substantia gelatinosa in L5~ S2 spinal cord posterior horn. The activity of enzyme was analysed with computer image analysis system. Results Compared with the control group, the activity of FRAP in NGF group was higher on the d 5 and d 10 after operation and the activity of AchE in NGF group was higher on the d 10 after operation. ConclusionIt is demonstrated that NGF could protect the mononeurons in spinal cord anterior horn and the sensory neurons in dorsal root ganglia after axotomy.

Objective To analyze the antimicrobial resistance profile of clinical isolates in Shanghai Xinhua Hospital Chongming Branch affiliated to Shanghai Jiaotong University School of Medicine , a member of China Antimicrobial Resistance Surveillance System, during 2015, for the purpose to facilitate rational antimicrobial therapy. Methods Strain identification?and?susceptibility?testing?were?carried?out?for?the?clinical?isolates?using?MicroScan?WalkAway?96?Automated?Systems and Kirby-Bauer method. Results In 2015, a total of 1815 isolates were collected, including gram-negative bacteria (73.2 %) and gram-positive bacteria (26.8 %). The top three frequently isolated species were Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. ESBL-producing strains were found in 36.3 % of the Escherichia coli isolates, 12.6 % of the Klebsiella (K. pneumoniae and K. oxytoca) isolates, and 28.0 % of the Proteus mirabilis isolates. The prevalence of carbapenem-resistant strains was 0.69 % in Enterobacteriaceae isolates. The prevalence of methicillin-resistant strain was 29.1 % in S. aureus, and 61.4 % in coagulase-negative Staphylococcus isolates. No more than 15 % of the Enterobacteriaceae isolates and no more than 20 % of the P. aeruginosa and Acinetobacter isolates were resistant to carbapenems. No vancomycin-or linezolid-resistant strains were found in Enterococcus or Staphylococcus. Conclusions Antibiotic-resistant clinical isolates are a serious threat for clinical antimicrobial treatment. We should pay more attention to such urgent situation and rational use of antibiotics.

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.

10.Surveillance of antibiotic resistance in the clinical isolates in Xinhua Hospital Chongming Branch, Shanghai Jiaotong University School of Medicine from 2015 to 2017
Chinese Journal of Infection and Chemotherapy 2018;18(6):621-626
Objective To investigate antimicrobial susceptibility profile of clinical isolates in Xinhua Hospital Chongming Branch affiliated to Shanghai Jiaotong University School of Medicine for rational use of antibiotics. Methods WHONET 5.6 software was used to analyze the distribution and susceptibility testing data of clinical isolates. Results A total of 5 278 bacterial isolates were collected from 2015 to 2017. The top three bacterial species were Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa, accounting for 24.8%, 16.1% and 8.4%, respectively. The prevalence of major antibiotic-resistant bacteria was increasing. The prevealence of carbapenem-resistant Enterobacteriaceae (CRE) was 0.8%, 3.5% and 7.0% in the 3 years. The prevalence of MRSA was 32.4%, 41.9%, and 51.3%, respectively. The prevalence of the Acinetobacter strains resistant to antibiotics, especially to imipenem and meropenem, increased from 20.3% to 64.6%. No vancomycin-or linezolid-resistant isolates were found in gram-positive bacteria. Conclusions The clinical bacterial isolates show increasing resistance to most antibiotics during the 3-year period in this secondary care general hospital. Especially, carbapenem-resistant Enterobacteriaceae poses a serious threat. Attention should also be paid to surveillance of antimicrobial resistance in secondary care general hospital.
