BACKGROUND: The main difficulties of whole-cell patch clamP are cell culture and whole-call current recording. OBJECTIVE: To reduce the difficulty of patch-clamp experiment by combining acute cell isolation with current separation technique. METHODS: A total of 40 wistar rats aged 4-7 days, irrespective of genders, were selected. The pallium of wistar rats were cut into slices with 400-600 μm, rested for 1 hour in artificial cerebrospinal fluid with gas mixture, simultaneously put in oxygen. The brain tissues were placed into artificial cerebrospinal fluid containing 16 u/mL(type X) and 2 u/mL(type XIV) proteinase, incubated for 60 minutes, and cleared the digestive enzyme. Under the whole-cell voltage clamp mode, the potential was hold at -80mV, depolarizing pulse stimulation from -60 mV to 60 mV, 10 mV step and 160 ms width. The total Tran membranes current was recorded, and then 70 mmol/LCsCI, 70mmol/L CsF was 11 μmol/L Na~+ channel blockers tetrodotoxin, 30 mmol/L tetraethylammonium, 1 mmol/L 4-AP was successively added into extracellular fluid. The inward sodium current, transient outward potassium current and delayed rectifier potassium current was recorded, and then the result was analyzed using clampfit. MAIN OUTCOME MEASURES:①Cell morphological observation; ②Whole-ceil current recording;③Inward sodium currentrecording; ④Outward potassium current recording.RESULTS AND CONCLUSION: The cell had clearly three-dimensional structure, smooth surface and whole neurodendrite or neuraxon. The cell viability could maintained for 8-10 hours at 25 ℃ temperature. The added 11 tetrodotoxin in extracellular fluid could block sodium Current. The outward potassium current could be blocked by tetraethylammonium with 30 mmol/L and 4-AP with 1 mmol/L. The calls harvested by modified rapid dissociation have good functions. Using current separation method, only specific blockers are needed, without extracellular fluid or electrode solution replacing, which can record the inward sodium current, transient outward potassium current, as well as delayed rectifier potassium current. This method can obviously improve the work efficiency than traditional one.

Objective To determine the causative organisms and antimicrobial susceptibility of community- and hospital-acquired pneumonia (CAP and HAP) in type 2 diabetes in Fujian Provincial Hospital. Methods The data of becteria spectrum and their drug susceptibility in patients with type 2 diabetes complicated by pulmonary infection were retrospectively analyzed in January 1995 to October 2006. Results The isolated bacteria of sputum culture of 494 cases included 73 gram-positive cocci(16.7%),139 gram negative bacilli(31.9%)and 224 fungus(51.4%).G+ cocci mainly included staphylococci,G-bacilli mainly included Klebsiella pneumoniae,Bowman immovability bacillus and Pseudomonas aeruginosa.In both CAP and HAP,fungus and G- bacilli were the dominant pathogens.The pathogenic bacteria were resistant to multi-antibiotics,and the resistant rates from HAP patients was higher than those from CAP. Of the bacterial strains isolated from blood culture,G-bacilli constituted 87.5%. Conclusions Fungus and G-bacilli were the dominant pathogens.Phlegm culture and drug sensitive test are helpful for reasonable use of antibiotics for patients with type 2 diabetes complicated by pulmonary infection in clinical practice.

Objective To investigate the clinical results of microsurgical free tissue transfers in pediatric reconstruction.Methods Between Janua~ 2004 and December 2010,twenty-seven free tissue transfers for reconstruction of various defects in 27 pediatric patients were performed.The average age at the time of reconstruction was 10.8 years(range:5-14 years).Fourteen patients were boys and 13 were girls.There were 5 tumor resection defects,sixteen posttraumatic defects and 6 burn contractures which consist of 19 fasciocutaneous flaps,six osteoseptocutaneous flaps and 2 muscle flaps.The mean operative time was 4 hours and 20 minutes.Results All flaps survived except 1 partial necrosis,with 96.3％ success rate.All patients were followed up 3 months to 4 years (mean,one and a half years).The appearance of the flaps was slightly overstaffed,but the color and texture were satisfactory.Conclusion Free tissue flap transfer is a safe,reliable,cost-and time-effective method for the reconstruction of various defects in children.

Objective:To evaluate the reliability of localization of the impacted teeth by assessing various conventional radiographies. Methods:32 patients with impacted teeth were included. The impacted teeth were localized by conventional roentgenographic techniques including panoramic radiography (PR) and linear tomography (LT).Results:Dentomaxillary orthopantomographic solution (PR,LT and PR combined with LT) clearly presented the position of the impacted teeth. Serial cross-section linear tomography also ensured the shape and axis of the impacted teeth captured on the radiograph. The accuracy of the localization was further verified by the surgical exposure in 5 cases. Conclusion:Orthopantomographic assessing can directly and precisely localize the buccal and lingual position of the impacted teeth.

Objective:To construct a recombinant adenovirus vector carrying human cytomegalovirus(hCMV) UL144 gene and to explore the biological characteristics of UL144 gene-modified DCs.Methods:The UL144 gene was amplified from hCMV DNA,which was extracted from hCMV-DNA positive serum.The recombinant adenovirus vector carrying hCMV UL144 gene was constructed with AdEasy system and then transfected into HEK293 cells to create recombinant adenovirus Ad-UL144.The expression of inserted gene was identified by RT-PCR.The recombinant adenovirus was then transfected into mice myeloid dendritic cells.The surface proteins of dendritic cells were analyzed by FACS,and cytokines in supernatant were detected by ELISA.T cell proliferation stimulated by gene-modified DC was examined by 3H-TdR uptake assay.Results:The UL144 gene was successfully cloned into the pAdEasy-1 plasmid.The recombinant adenovirus Ad-UL144 was packed in HEK293 cells,with a viral titer of 3?1010 pfu/ml.DCs infected with AdCMV-UL144 had markedly decreased surface expression of CD80,CD86 and I-Ad(P

Objective: To investigate clinical and hematological features of malignant lymphoma (ML) combined with venous thromboembolism (VTE). Methods:The clinical data of 65 patients with ML combined with VTE were collected between October 2010 and April 2014 and then retrospectively reviewed. Coagulation function and hemorheology were analyzed. Results:The proportion of males and females among patients with ML combined with VTE was 2.61:1. ML combined with VTE was mainly observed in patients with end-stage cancer. The highest incidence (81.54%) of ML combined with VTE was found in StageⅢB-Ⅳtumor. Among 65 patients with VTE, 43 (66.15%) were found after ML was diagnosed, 55 (84.62%) were deep vein thrombosis (DVT), 7 (10.77%) were pulmonary embolism (PE), and 3 (4.62%) were complicated with both DVT and PE. Common DVT locations were the upper limb and the neck vein of 37 cases (67.27%). Clinical manifestations of ML combined with DVT are limb pain, swelling, and increased skin temperature. Unexplained difficulty in breathing, chest pain, and syncope are also found in ML combined with PE. The total effective rate of 55 cases with DVT was 49.09%, and the rate of those cases with PE was 14.29%. The levels of platelet aggregation, D-dimer, high cut blood viscosity, low cut blood viscosity, plasma viscosity, hematocrit, assembly index of erythrocyte, and rigidity index of erythrocyte were significantly higher in patients with ML combined with VTE than in patients with ML alone;by contrast, APTT, erythrocyte sedimentation rate, deformability index of erythrocyte, and average velocity of blood flow were reduced in patients with ML combined with VTE than in patients with ML alone. Conclusion:DVT, which exhibits high incidence in males, is the most common type observed in ML combined with VTE. DVT is commonly manifested in the upper limb and the neck vein;furthermore, DVT is mainly observed in patients with end-stage cancer. Hematological indexes indicated changes in the sensitivity state of thromboembolism.
