Objective:To assess the anatomy of superficial circumflex iliac artery perforator (SCIP) and its feasibility for tongue re-construction after tumor resection. Methods:From January 2014 to January 2015, a total of 15 patients with oral maxillofacial defects underwent SCIP flap surgery. Perforator identification and SCIA course were performed intra-operatively. The relationships among the SCIA, deep circumflex iliac artery (DCIA), and superficial inferior epigastric artery (SIEA) were determined intra-operatively. Surgical procedures, measurement of vessel's caliber and pedicle's length, SCIP flap anatomy, and their outcomes were described. Results:Flap mean thickness was approximately 1.2±0.3 cm. The mean diameter of the SCIA was 0.7±0.2 cm, and that of the superficial circumflex iliac vein was 1.2±0.2 cm. The relationships among SCIA, DCIA, and SIEA were described and subdivided into typeⅠ(8/15), typeⅡ(2/15), typeⅢ(2/15), typeⅣ(2/15), and typeⅤ(1/15) in intra-operative dissection. The flap sizes were in the range from 6 cm × 4.5 cm to 11 cm × 10 cm. A total of 14 SCIP flaps survived, and 1 SCIP flap underwent necrosis. Conclusion:The SCIP flap is a reliable, thin, and pliable flap with long vascular pedicles and hidden donor site morbidity. Its texture is a perfect match for tongue defect reconstruc-tion.

Objective:To study the modulatory effect of hydrogen sulfide (H2S) on oxidative stress in the development of pulmonary hypertension induced by hypoxia. Methods:Twenty male Wistar rats were randomly divided into control group (n=6), hypoxic group (n=6) and hypoxia+NaHS group (n=8). Hypoxic challenge was performed everyday for 21 days. NaHS solution was injected intra-peritoneally everyday before hypoxic challenge for rats in the hypoxia+NaHS group. After 21 days of hypoxia, the mean pulmonary artery pressure(mPAP) was measured by cardiac catheterization. The weight ratio of right ventricle to left ventricle+septum [RV/(LV+SP) ] was also measured. The lung homogenates were assayed for total antioxidant capacity(T-AOC), superoxide dismutase (SOD), oxidized glutathione (GSSG), reduced glutathione (GSH), malondiadehyde(MDA) and hydroxy radical(?OH), and the SOD mRNA levels were assayed by real time polymerse chain reaction. Results: After three weeks of hypoxic disposure, hypoxic hypertension and vascular remodeling developed. Compared with the control group, the mPAP[(23.7?2.2) mm Hg vs. (16.3?3.7) mm Hg,P

BACKGROUND: With the extensive application of small animal imaging and imaging studies, it requires the investigators to master the cross-sectional anatomy of mice, but the anatomy of mouse nasal cavity and sinuses cannot be obtained through vivisection.OBJECTIVE: To establish a highly precise serial colorful sectional image data set of mice using digital virtual human technology.METHODS: An adult male Balb/c mouse was killed for freezing embedded using modified Kawamoto's method and was then serially scanned at 5 μm of thickness by Leica CM3600XP cryostat microtome. The sectional images were photographed with a 24 million pixels Nikon D750 camera and stored as JPG files. All images were preliminarily registered by manually cropping the images based on the edge of block surface using software photoshop 7.0. Then, the image size, brightness and registration were corrected and adjusted, and the format of the images was unified as TIFF. The data set was imported to Amira 6.0 and was registered again with least square method. The quality of the data set was evaluated by three-dimensional reconstruction. RESULTS AND CONCLUSION: A total of 6034 original images with a size of 87 GB were captured. After cropping, adjusting and registration, the final size was 184 G. The mouse three-dimensional reconstruction model was satisfactory. To conclude, the data set established using the method and system mentioned above is characterized by high resolution and high-fidelity, which might facilitate the further study of the precise anatomy of mice and other fundamental experiments.

Objective To explore the risk factors of severe pneumonia caused by multi-drug resistant Klebsiella pneumonia,and antimicrobial drug resistance among these isolates.It may help to prevent and control the disease and promote to rational use of antibiotics.Methods We conducted the case-control study in our PICU.It included 89 patients with severe pneumonia caused by multi-drug resistant Klebsiella pneumonia as case group and 68 patients with severe pneumonia caused by Klebsiella pneumonia as control group during the same period.To compare the two groups on irrationality use of antibiotics (especial for third generation cephalosporin),length of stay,tracheal cannula,time of mechanical ventilation and underlying conditions (malnutrition,congenital heart disease,heredity and metabolic disease).Antimicrobial susceptibilities among 89 multi-drug resistant Klebsiella pneumonia isolates were analyzed.Results There were 63 cases (70.79％) for irrationality use antibiotics in case group,while there were 27 cases (39.70％) in control group (P ＜ 0.01).The cases for length of stay over 7 days in case group (48 cases,53.93％) were more than those cases with the same situation in control group (12 cases,17.65 ％) (P ＜ 0.01).Thirty-eight cases (42.69 ％) needed mechanical ventilation therapy in case group,while 16 cases (23.53％) needed mechanical ventilation therapy in control group (P ＜ 0.01).The cases for duration of mechanical ventilation over 5 days in case group (18 cases,20.22％) were more than those cases in control group (5 cases,7.35％) (P ＜0.05).The cases with underlying disease in case group (13 cases,14.61％) were more than those cases in control group (2 cases,2.94％) (P ＜ 0.05).Multi-drug resistant Klebsiella pneumonia isolates demonstrated that high-level resistance for penicillins,cephalosporins,aminoglycosides and quinolones,but still susceptible to carbapenems.Conclusion Several risk factors are associated with severe pneumonia caused by multi-drug resistant Klebsiella pneumonia,including irrational use of antibiotics (especial for third generation cephalosporin),long term of length of stay,endotracheal intubation,long term of mechanical ventilation,and having underlying disease (malnutrition,congenital heart disease,heredity and metabolic disease).Multi-drug resistant Klebsiella pneumonia isolates demonstrated that high-level resistance for penicillins,cephalosporins,aminoglycosides and quinolones,but still susceptible to Carbapenems.Carbapenems should be used as first-line drugs for severe pneumonia caused by multi-drug resistant Klebsiella pneumonia.

OBJECTIVETo explore the clinical effect of the sacrococcygeal space injection for the treatment of failed back surgery syndrome.

METHODSFrom July 1998 to October 2012,47 patients with failed back surgery syndrome were treated and included 39 males and 8 females with an average age of 61.5 years old ranging from 35 to 89 years old. Among them,41 patients experienced one time of operation, 6 patients with twice of operation. Forty-one patients underwent single,bilateral fenestration or central laminectomy decompression, discectomy. Six patients underwent total laminectomy discectomy and inter body fusion and pedicle screw fixation. All patients were examined by X-ray plain film, CT or MRI before treatment. The anticoagulation was discontinuation before treatment. The needle was put into the sacrococcygeal gap at prone position in the sense of frustration,suction without cerebrospinal fluid and blood,with injection of Mailuoning (Chinese characters: see text) 15 ml. The pain was assessed by VAS before and after treatment. The Oswestry low back pain disability index and survival quality interference degree were evaluated.

Objective To evaluate the use of gated SPECT in patients with hypertrophic obstructive cardiomyopathy (HOCM) and the effects of percutaneous transluminal septal myocardial ablation (PTSMA) on myocardial perfusion.Methods 99 Tcm-methoxyisobutylisonitrile (MIBI) and 18F-fluorodeoxyglucose (FDG) images were performed in 31 HOCM patients before PFSMA and in 15 patients 3-7 d after PTSMA.The images in different left ventricular segments were analysed by using scores.Results In 99Tcm-MIBI images, uptake decreased at the septal regions in 12 HOCM patients (80.0%, 12/15) after PTSMA, 18F-FDG images also showed decreased uptake at the septal regions in 5 HOCM patients (33.3%, 5/15) after PTSMA.Conclusion 99Tcm-MIBI images might be an important method to evaluate PTSMA results, and 18 F-FDG images showed important value as reference.

Objective To investigate the effects of uncoupling protein 2 (UCP2) on the myocardial cells of mice with type 2 diabetes mellitus combined with hyperuricemia (HUA), and clarify the mechanism thereof. Methods The mouse cardiac myocytes (MCM) cultured with 25mmol/L high glucose (HG) medium were divided into two groups: HG plus 300μmol/L sodium palmitate for 18 hours as high glucose and high fat (HG+HF) group, and HG+HF plus 1500μmol/L uric acid (UA) for 18 hours as HG+HF+HUA group. Then the myocardial cells in HG+HF+HUA group, by use or not use UCP2 inhibitor genipin, were further divided into two groups: vehicle group and genipin group. In order to verify the mechanism of UCP2 in myocardial cells injury caused by high glucose, high lipid and high uric acid, the myocardial cells were divided again into genipin group and genipin+N-acetylcysteine (NAC) group. Accordingly, the apoptosis of myocardial cells were measured by flow cytometry at specific time, the mRNA and protein expressions of UCP2 were determined by q-PCR and Western blotting, and the levels of reactive oxygen species (ROS) were detected by DHE staining and ELISA. Results The apoptosis rate of myocardial cells increased obviously, and the expression levels of UCP2 decreased and of ROS elevated significantly in HG+HF+HUA group than in HG+HF group (P<0.05). As the expression levels of UCP2 decreased by genipin intervention, the apoptosis rate of myocardial cells and ROS level in HG+HF+HUA group increased more obviously (P<0.05). In contrast, such an effect was reversed by the application of antioxidants NAC (P<0.05). Conclusion UCP2 can inhibit oxidative stress and alleviate the apoptosis of myocardial cells induced by high glucose, high fat and high uric acid.
