Objective To explore the clinical application value of plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) in diagnosis and treatment of symptomatic patent ductus arteriosus (sPDA) in preterm infants. Methods A total of 107 preterm infants with gestational age of 28-32 weeks and birth weight less than 1500 g who were admitted to the neonatal intensive care unit from October 2013 to September 2014 were recruited. Plasma NT-proBNP were on 4th and 7th day after birth. The echocardiography examination was performed within 30 minutes after the blood was drawn. According to the echocardiography examination on 4th day after birth, the infants were divided into the patent ductus arteriosus (PDA) group (n?=?39) and the control group (n?=?68). According to whether there were signiifcant hemodynamics changes of ultrasonography and clinical symptoms, the PDA group were classiifed into the sPDA group (n?=?20) and the asymptomatic PDA group (asPDA, n?=?19). Then according to whether ibuprofen was taken, the sPDA group was further divided into treatment group (n?=?13) and non-treatment group (n?=?7). Results On the 4th day after birth, the level of plasma NT-proBNP in the sPDA group was signiifcantly higher than that in asPDA group, and the level of plasma NT-proBNP in asPDA group was signiifcantly higher than that in the control group (P??0.05). In the treatment group, the level of plasma NT-proBNP on the 7th day after birth was signiifcantly lower than that on the 4th day after birth (P??0.05). In PDA group, the level of plasma NT-proBNP on the 4th day after birth was positively correlated with ductus arteriosus (DA) diameter, ratio of the left atrium to aortic root diameter (LA/AO ratio) and transductal diameter-to-left pulmonary artery ratio (TDD/LPA) (r?=?0.498-0.670, respectively). The area under receiver operator characteristic (ROC) curve for prediction of sPDA by the plasma NT proBNP on the 4th day after birth was 0.969 (95%CI:0.938-1.000). When the NT-proBNP was 13964 pg/ml on the 4th day after birth, the sensitivity for diagnosis sPDA was 95%, the speciifcity was 95.4%. Conclusions The level of plasma NT-proBNP is signiifcantly higher in preterm infants with sPDA and is decreased after treatment. Plasma NT-proBNP on the 4th day after birth is a sensitive marker for predicting sPDA. Dynamic monitoring of plasma NT-proBNP has important clinical value in selection of the treatment strategy in preterm infants with PDA.

Objective To investigate the clinical efficacy of anterior pelvic plating plus percutaneous lumbo-iliac rod/screw fixation in the treatment of pelvic fractures which are vertically and rotationally unstable and combined with unilateral sacral fracture of Denis type Ⅱ.Methods From January 2008 to November 2012,19 patients were treated for compound injury to the anterior and posterior pelvic rings complicated with sacral fracture of unilateral Denis type Ⅱ using anterior pelvic plating plus posterior percutaneous fixation of lumbo-ilium with screws.Their improvement in neurological function,reduction outcome and clinical effectiveness were evaluated by comparing preoperation and 2 years postoperation in terms of visual analogue scale (VAS),Japanese Orthopaedic Association (JOA) score for lower back pain,MOS Item Short-form health survey (SF-36 comprehensive scale),modified Roland-Morris Disability questionnaire (RDQ),Oswestry disability index (ODI),Gibbons overall scale,Majeed total score,sacral kyphosis abnormity,bias of sagittal/coronal vertical axis (SVA/CVA),pelvic incidence,pelvic tilt,lumbar lordosis,vertical displace,and leg length discrepancy.Results The differences respectively reached statistical significance for the aforementioned clinical and imaging parameters between preoperation and 2 years postoperation (P ＜ 0.05).By Majeed scoring,13 cases were rated as excellent,4 as good and 2 as fair.By Tometta/Matto scoring postoperatively,the fracture reduction was rated as excellent in 12 cases,as good in 6 and as fair in one.The complications of incision infection or necrosis,secondary neurovascular damage,implant failure or mal-union was not observed.Perfect nerve functional recovery and sufficient imaging reduction were achieved in all but one patient who had to receive decompression and release for sacral canals or foramens.According to Mohammad criteria,15 patients were engaged in the jobs with the same intensity and property as their pre-injury ones.Conclusions The simultaneous hybrid performance of anterior reconstruction plating combined with unilateral lumbar/sacral pedicle and iliac screwing may be a safe,reliable and satisfactory treatment for pelvic fractures of AO/Tile C1 type which involve unilateral sacral Denis type Ⅱ.

A novel method based on the separation and enrichment effect of magnetic beads and the fully complementary hybridization of two DNA strands was developed for highly sensitive detection of bacterial DNA using a surface-enhanced Raman spectroscopy (SERS) with 5,5’-dithio-bis(2-nitrobenzoic acid) (DTNB)-modified gold nanoparticles as reporter probes. Capture probe was immobilized onto the surface of streptavidin-enwrapped magnetic beads ( SA-MB ) through high affinity between biotin and avidin, by which the target bacterial DNA sequences that connected with the reported probe decorated AuNPs with DTNB and SH-DNA ( AuNPs@DTNB@DNA) were captured and loaded onto the magnetic beads by the hybridization reaction with the capture probe. Compared with previous methods, this design shortened the distance between particles by the ways that the magnetic beads tempted to nanoparticles aggregation, and produced the plasma resonance coupling effect, which increased the SERS signal significantly. The results showed that, under the optimized conditions and in the concentration range from 5 pmol/L to 5 nmol/L, the method performed a good linear relationship between Raman intensity and DNA concentration. The limit of detection ( LOD) of bacterial DNA was estimated to be 5 pmol/L. The method is simple and low cost, and can be used in the sensitive and selective detection of bacterial DNA.

Birt–Hogg–Dubé (BHD) syndrome, a hereditary renal cancer syndrome caused by mutations in the folliculin (FLCN) gene, is characterized by the presence of fibrofolliculomas, pulmonary cysts, spontaneous pneumothorax, and renal cell carcinoma (RCC). Few BHD syndrome cases have been reported in Asian countries, and cutaneous presenta-tions are relatively rare in Asian patients. Asian BHD patients may be misdiagnosed due to their atypical manifesta-tions. Here, we report two Chinese BHD patients with novel FLCN mutations (c.946-947delAG in exon 9 and c.770-772delCCT in exon 7). Both of them had RCC and spontaneous pneumothorax without fibrofolliculomas. In patients with RCC and pulmonary cysts but without cutaneous lesions, screening for mutations in the FLCN gene should be performed, especially for those with a family history of RCC or pulmonary cysts (pneumothorax).

Objective To explore the methodology of suturing the upper margin of the orbicularis muscle in pretarsal orbicularis myocutaneous flap to the levator aponeurosis,simulating the mechanism of fibers from the levator aponeurosis to the dermis in natural double-eyelid in blepharoplasty.Methods Pretarsal orbicularis myocutaneous flap was harvested.Dissection between the orbital septum and the levator aponeurosis was performed originating from the upper margin of the tarsi until to the levator muscle.The upper margin of the orbicularis muscle in pretarsal orbicularis myocutaneous flap was sutured to the levator aponeurosis.The lower skin margin to the orbital septum to the upper skin margin was sutured interruptedly.Patients with medial epicanthus were performed epicanthoplasty at the same time.Results 136 eyes in 68 patients were performed with double-eyelid blepharoplasty using this method.62 patients were followed-up for 1 month and 53 patients were followed-up for 3 months.They all reported satisfactory aesthetic results.Conclusions Double-eyelid blepharoplasty using this method accords with the physiological mechanism in natural double-eyelid.Postoperative double-eyelid is natural with little tumefaction.This method can avoid double-eyelid fold retraction and multi-fold occurrence.

Objective To compare the efficacy of orotracheal intubation after rapid induction and nasotracheal intubation after slow induction assisted by fiberoptic bronchoscope (FOB) in patients with obstructive sleep apnea syndrome (OSAS).Methods Forty ASA Ⅱ patients with OSAS and hypertension, aged 38-64 yr, weighing 82-123 kg, undergoing uvulopalatopharyngoplnsty, were randomly allocated into 2 groups (n = 20 each): group Ⅰ awake nasotracheal intubation through FOB after slow induction and group Ⅱ orotracheal intubation through laryngoscope and FOB after rapid induction. MAP and HR were recorded immediately after anesthesia induction and intubation. The intubation time was recorded, and rate of successful intubation, incidences of tschycardia, hypertension and myocardial ischemia during intubation, and satisfactory rate of otolaryngologists with airway management were calculated. Results The rate of successful intubation were significantly higher, MAP and HR after induction were significantly lower, incidences of tachycardia, hypertension and myocardial ischemia during intubation were significantly lower, and satisfactory rate of otolaryngologists was significantly higher in group Ⅱ than in group Ⅰ ( P < 0.05). Four patients in group Ⅰ had nasal bleeding after extubation. Conclusion Orotracheal intubation after rapid induction assisted by FOB provides less hemodynamic response to endotracheal intubation and higher success rate with less injury to the airway in patients with OSAS than nasotracheal intubation after slow induction assisted by FOB.
