1.  Primary urinary bladder adenosquamous carcinoma complicated with lower limb deep venous thromboses: a case report 
Primary urinary bladder adenosquamous carcinoma is extremely rare and only a few cases have been reported in English literatures. Its biological behavior remains unclear. Here we reported a 60-year-old male patient with lower limb deep venous thromboses associated with primary urinary bladder adenosquamous carcinoma. A color ultrasonography showed right stock total venous thrombosis and right great saphenous vein thrombosis of lower limb. Contrast-enhanced computed tomography (CT) scan confirmed a 3.17 × 3.33 × 3.84 cm enhancing mass within the urinary bladder along the right lateral and posterior wall. Histopathological examination revealed adenosquamous carcinoma of urinary bladder, with extensive infiltration of the muscle layer. To the best of our knowledge, this is the first report of primary urinary bladder adenosquamous carcinoma complicated with deep venous thromboses in lower limb.

2.  catena-Poly[[[diaqua­cadmium]-μ-2,2′-(1,2-phenyl­enedi­oxy)diacetato] mono­hydrate] 
In the title coordination complex, {[Cd(C10H8O6)(H2O)2]·H2O}n the CdII atom is seven-coordinated in a distorted penta­gonal–bipyramidal geometry, the penta­gonal plane comprising four O-atom donors from the 2,2′-(1,2-phenyl­enedi­oxy)diacetate chelate ligand together with a bridging carboxyl­ate O-atom donor, with the axial sites occupied by two water mol­ecules. The resulting helical chains extend along the b axis and are inter­connected by extensive O—H⋯O hydrogen-bonding inter­actions, which also involve the water mol­ecule of solvation, giving a three-dimensional structure.

3.  Improvement of Amperometric Sensor Used for Determination of Nitrate with Polypyrrole Nanowires Modified Electrode 
Sensors (Basel, Switzerland)  2005;5(12):580-593.
Polypyrrole(PPy) nanowire modified electrodes were developed by template-free electrochemical method based on graphite electrode. The modified electrode was characterized by their amperometric response towards nitrate ions. Before reduction of nitrate ions, electrochemical solid-phase extraction (EC-SPE) of nitrate in/on modified electrodes was conducted. It is found that the unusual nanowired structure of polypyrrole layer (instead of well known cauliflower structure) allows us to increase the effective surface area of the electrode and subsequently the sensitivity. And the effects of electrochemical preparation parameters of PPy nanowire modified electrodes on their corresponding characters were evaluated. The experimental results show that the electrochemical preparation parameters of the modified electrodes such as scan rate, polymerization potential, temperature of polymerization solution and polymerization time have significantly effects on the morphology of PPy nanowires and subsequently effective surface area of the electrode and electroreduction current density of nitrate. The determination sensitivity may be varied according to the modification parameters. Under a certain polymerization conditions, the corresponding sensitivity reaches 336.28 mA/M cm2 and the detection limit is 1.52×10-6 M. The proposed method was successfully applied in the detection of nitrate in the real samples.
