A rapid method was developed for the determination of 9 organophosphorous flame retardants ( OPFRs) in textiles by ultra high performance liquid chromatography tandem electrospray ionization mass spectrometry ( UHPLC-MS/MS ) . Analytes in textile samples were extracted in a closed bottle at 50℃ with methanol by ultrasonic extraction for 30 min. And then, the extracted solution was injected after filtration and determined by UHPLC-MS/MS. Target analytes were separated by C18 column and methanol/water containing 5. 0 mmol/L NH4 COOH. The positive electrospray ionization and multiple reaction monitoring mode ( MRM) was utilized. The matrix effect (ME) could be compensated by adjusting the concentration of NH4COOH and the composition of the mobile phase after careful investigation with blank samples. An external standard calibration method was chosen to the quantitative analysis. Under the optimized conditions, method precision represent with relative standard deviations (RSDs) was 5. 2% (TOCP) -12. 5% (TRIS) for cotton, 6. 4%(TBEP)-13. 8% (TRIS) for polyester, and 6. 9% (TDCP) -14. 5% (TEPA) for wool samples. The recoveries for standard addition were in the range of 52 . 5% ( TEPA ) -116 . 4% ( TPP ) . The limits of quantification (LOQ, S/N=10) were between 1. 0 (TBP) and 10. 0 (TRIS) μg/kg.

Objective To summarize the preliminary experience of coils, Onyx and covered stents for the treatment of carotid-cavernous sinus fistula (CCF). Methods Of the 25patients with CCF, 22 were traumatic CCF, and 3 were spontaneous CCF; the fistula orifices of 14 patients were located in the cavernous segment of right internal carotid artery (ICA), and 11were located in the cavernous segment of left ICA. According to the Barrow classification,Types A, C, and D were 22,2, and 1, respectively. Eighteen patients were treated with Guglielmi detachable coils alone, 1 was treated with Guglielmi detachable coils and Onyx, 2 were treated with Onyx alone, and 4 were treated with covered stents. Results Intracranial bruit disappeared immediately in all patients after the procedures. Postoperative angiography showed complete occlusion of the fistula orifices, the symptoms disappeared after 1 to 20 days, and there were no death and procedure-related complications. The recanalized ICAs were patent in patients (12/18) treated with coils, and the ICAs were patent in 4 patients treated with the covered stents.The ICAs were patent in 2 patients treated with Onyx, the ICA was patent in 1 patent treated with detachable coils and Onyx. One patient with traumatic CCF treated with coils had clinical recurrence, and was cured after re-embolization with coils. The remaining patients were followed-up for 6 to 24 months, and no recurrence of clinical symptoms was found. The followup cerebral angiography of 6 patients was obtained, and no CCF recurrence was observed.Conclusion Endovascular treatment with Guglielmi detachable coils, Onyx, and covered stents is a safe and useful method for closing CCFs.

OBJECTIVE: To compare the efficacy of sublingual immunotherapy (SLIT) with standardized house dust mite extract in mono sensitized and polysensitized children with allergic rhinitis. METHOD: One hundred and fifty-seven children who were sensitized to house dust mites and treated with SLIT for house dust mites for at least 1 year were studied. The monoallergen sensitized group included patients who were sensitized to Dermatophagoides pteronyssinus and/or Dermatophagoides farinae (n=92). The polyallergen sensitized group included patients who were simultaneously sensitized to house dust mites and other allergens (n = 65). A standardized extract of house dust mites was used for immunotherapy. Antiallergic medication and the total nasal symptom score (TNSS) were evaluated before and 1 year after SLIT. RESULT: One hundred and twenty-five children completed 1-year SLIT. The TNSS improved significantly after SLIT in both groups, with monoallergen sensitized group 11.42 +/- 1.60 vs 3.55 +/- 1.57 (t=30.03, P<0.01), and polyallergen sensitized group 11.54 +/- 1.55 vs 3.23 +/- 1.56 (t=27.76, P< 0.01). But the change in the TNSS did not differ significantly between the groups (TNSS change, 7.94 +/- 2.24 vs 8.32 +/- 2.18, P>0.05). The AMSs were decreased significantly after SLIT in both groups, with monoallergen sensitized group 1.62 +/- 0.44 vs 0.56 +/- 0.37 (t=15.01, P<0.01), and polyallergen sensitized group 1.63 +/- 0.43 vs 0.50 +/- 0.40 (t=13.49, P<0.01). But the AMSs improvement did not differ significantly between the two groups(AMSs change 1.03 +/- 0.58 vs 1.13 +/- 0.61, P>0.05). CONCLUSION In polysensitized allergic rhinitis patients, SLIT for D pteronyssinus and/or D farinae produced improvements in both nasal symptoms and rescue medication scores comparable to those in mono sensitized patients. SLIT for D pteronyssinus and/or D farinae should be considered in polysensitized allergic rhinitis patients.

Objective To evaluate the clinical application of modified bony landmark measurement ( MBLM ) to deal with leg length discrepancy ( LLD ) during total hip arthroplasty ( THA ). Methods We retrospectively analyzed the 36 patients in whom MBLM was used to deal with LLD during THA from January 2014 to May 2015 at Department of Orthopaedics, The Second Hospital of Fuzhou. They were 17 men and 19 women, aged from 42 to 78 years ( average, 68.7 ± 10.1 years ). They were divided into 3 groups according to their pre-operative LLD value ( d ) : 16 cases in group A with d≤10 mm, 11 cases in group B with 10 mm ＜d≤20 mm and 9 cases in group C with d ＞ 20 mm. After the sizes of prosthetic cup and femoral component and the location of implant were determined using preoperative X-ray, a special formula was used to calculate the prosthetic length of femoral head neck and the osteotomy area at the femoral neck. MBLM was used to measure the leg lengths before hip joint dislocation and after placement of the hip implant. The neck length and depth of the femoral component was adjusted according to the measurements. Post-operative X-ray was used to measure the LLD ( d'). The value of MBLM in judgment of LLD during THA was assessed by comparison of d and d' and analysis of distribution of d' . Results The postoperative d' ( 6.0 ± 3.0 mm) was signifi-cantly shorter than the preoperative d ( 11.0 ± 5.0 mm) ( t＝5.145, P ＜0.001 ). There were 30 cases with d' ≤ 10 mm, 6 cases with 10 mm ＜d'≤ 20 mm and 0 case with d' ＞ 20 mm. The cases with d'≤ 10 mm were significantly more than those with d ≤ 10 mm and the cases with d' ＞ 20 mm significantly fewer than those with d ＞ 20 mm ( χ2＝15.500, P＝0.000 ) . Conclusion MBLM used during THA is a reliable method to judge the leg lengths so that LLD can be effectively reduced after THA.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.
