Abstract: Background and objective Perioperative management of pain associated with the prognosis of cancer patients. Optimization of perio-perative analgesia method, then reduce perioperative stress response, reduce opioiddosage, to reduce or even avoid systemic adverse reactions and elevated levels of tumor markers. Serum levels of tumor markers in patients with lung cancer are closely related to tumor growth. Clinical research reports on regional anesthesia effect on tumor markers for lung cancer are still very little in domesticliterature. The aim of this study is to evaluate the effects of thoracic paraverte-bral block on postoperative analgesia and serum level of tumor marker in lung cancer patients undergoing video-assisted thoracoscopic surgery. Methods Lung cancer patients undergoing video-assisted thoracoscopic surgery were randomly divided into 2 groups (n=20 in each group). The patients in group G were given only general anesthesia. The thoracic paravertebral blockade (PVB) was performed before general anesthesia in patients of group GP. The effect of PVB was judged by testing area of block. Patient controlled intravenous analgesia (PCIA) pump started before the end of surgery in 2 groups. Visual analogue scale (VAS) score was recorded after extubation 2 h (T1), 24 h (T2) and 48 h (T3) after surgery and the times of PCIA and the volume of analgesic drugs used were recorded during 48 h after surgery. The serum levels of carcino-embryonic antigen (CEA), carbohydrate antigen 199 (CA199), carbohydrate antigen 125 (CA125), neuron-specific enolase (NSE), cytokeratin 19 fragment (CYFRA21-1) and squamous cell carcinoma (SCC) in 40 lung cancer cases undergoing video-assisted thoracoscopic lobectomy were measured before operation and 24 h after operation. Results Forty American Society of Anesthesiologists (ASA) physical status I or II patients, aged 20 yr-70 yr, body mass index (BMI) 18 kg/m2-25 kg/m2, scheduled for elective video-assisted thoraeoscopic lobectomy, VAS scores at T1 and T2 were lower in group GP than those in group G (P=0.013, P=0.025, respectively), PCIA times during postoperative analgesia 24 h and 48 h were lower in group GP than those in group G (P=0.021, P=0.026, respectively), analgesic volume used during postoperative analgesia 24 h and 48 h were lower in group GP than those in group G (P=0.006, P=0.011, respectively). The level of tumor marker at post-operative were not significantly decreased than preoperative in both groups (P>0.05). Conclusion Patients in group G feel more painful and a higher dosage of dezocine is required to

Energies , 2012, DOI: 10.3390/en5104027
Abstract: The radial-radial flux compound-structure permanent-magnet synchronous machine (CS-PMSM), integrated by two concentrically arranged permanent-magnet electric machines, is an electromagnetic power-splitting device for hybrid electric vehicles (HEVs). As the two electric machines share a rotor as structural and magnetic common part, their magnetic paths are coupled, leading to possible mutual magnetic-field interference and complex control. In this paper, a design method to ensure magnetic decoupling with minimum yoke thickness of the common rotor is investigated. A prototype machine is designed based on the proposed method, and the feasibility of magnetic decoupling and independent control is validated by experimental tests of mutual influence. The CS-PMSM is tested by a designed driving cycle, and functions to act as starter motor, generator and to help the internal combustion engine (ICE) operate at optimum efficiency are validated.

Chinese Science Bulletin , 2001, DOI: 10.1007/BF02900587
Abstract: The Central Guizhou and Yichang Uplifts are present in central Guizhou to western Hubei. Biostratigraphic evidences from more than 20 sections in 14 counties of this region provide the data about the duration of these uplifts. Although this duration differs from locality to locality, it is mainly from Ashgillian to Rhuddanian. The uplifts result from a horizontally driven movement to the South China Paleoplate from an uncertain block in southeast. Global sea-level drop during the end of the Ordovician made the uplifts obvious, particularly the Central Guizhou Uplift. It might have emerged above sea level in the short interval between the Ordovician and Silurian.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0080435
Abstract: Enterococcus faecalis is increasingly becoming an important nosocomial infection opportunistic pathogen. E. faecalis can easily obtain drug resistance, making it difficult to be controlled in clinical settings. Using bacteriophage as an alternative treatment to drug-resistant bacteria has been revitalized recently, especially for fighting drug-resistant bacteria. In this research, an E. faecalis bacteriophage named IME-EF1 was isolated from hospital sewage. Whole genomic sequence analysis demonstrated that the isolated IME-EF1 belong to the Siphoviridae family, and has a linear double-stranded DNA genome consisting of 57,081 nucleotides. The IME-EF1 genome has a 40.04% G+C content and contains 98 putative coding sequences. In addition, IME-EF1 has an isometric head with a width of 35?nm to 60?nm and length of 75?nm to 90?nm, as well as morphology resembling a tadpole. IME-EF1 can adsorb to its host cells within 9 min, with an absorbance rate more than 99% and a latent period time of 25?min. The endolysin of IME-EF1 contains a CHAP domain in its N-terminal and has a wider bactericidal spectrum than its parental bacteriophage, including 2 strains of vancomycin-resistant E. faecalis. When administrated intraperitoneally, one dose of IME-EF1 or its endolysin can reduce bacterial count in the blood and protected the mice from a lethal challenge of E. faecalis, with a survival rate of 60% or 80%, respectively. Although bacteriophage could rescue mice from bacterial challenge, to the best of our knowledge, this study further supports the potential function of bacteriophage in dealing with E. faecalis infection in vivo. The results also indicated that the newly isolated bacteriophage IME-EF1 enriched the arsenal library of lytic E. faecalis bacteriophages and presented another choice for phage therapy in the future.
Are volatile anesthetics neuroprotective or neurotoxic?

Medical Gas Research , 2012, DOI: 10.1186/2045-9912-2-10
Abstract: More than 20 millions of patients each year have surgeries in the USA. The majority of these surgeries are performed under general anesthesia. About 80% of them receive volatile anesthetics as their primary anesthetics [1]. Since the first use of ether, a volatile anesthetic, in 1842, volatile anesthetics have be the major class of general anesthetics used in the clinical practice for near 160 years.Although it is still controversial among the experts, it is generally accepted that general anesthesia minimally includes the following components: unconsciousness, insensateness, analgesia and amnesia. Many experts will also add muscle relaxation and bluntness of cardiovascular response to surgical stimulation into the components of general anesthesia. Volatile anesthetics, unlike most intravenous anesthetics, have pharmacological properties to provide all components of general anesthesia [2]. Thus, volatile anesthetics are full general anesthetics and, theoretically, single volatile anesthetic can be used to provide a patient with full general anesthesia for surgery. In addition, volatile anesthetics take effects very quickly. Most patients anesthetized by these drugs recover smoothly and quickly. With the aid of modern equipment, their use is very easy and their concentrations can be accurately monitored. For these reasons, volatile anesthetics have been popular drugs used in clinical practice. Modern volatile anesthetics that are used in the USA include isoflurane (CHF2-O-CHCl-CF3), sevoflurane (CH2F-O-CH-(CF3)2) and desflurane (CHF2-O-CHF-CF3). Halothane (CF3-CHBrCl) was used clinically for more than 40 years and started to be phased out during 1990s as newer volatile anesthetics become popular. All of these volatile anesthetics are halogenated hydrocarbons.In addition to the anesthetic properties, volatile anesthetics have been thought to have neuroprotective effects for a long time [3,4]. Although the potential for volatile anesthetics to induce cell injury has be
