Inflammatory bowel disease (IBD) could lead to the complexity of intra-abdominal pathology and patients' malnutrition,which might greatly increase the risk of operation.Laparoscopic minimally invasive surgery is playing an important role in the treatment of IBD,with the advantages of faster postoperative recovery,shorter duration of hospital stay and lower incidence of postoperative complications.And some new techniques for IBD have been reported in the western countries,such as single-incision laparoscopic surgery,natural orifice transluminal endoscopic surgery,robot-assisted laparoscopic surgery and so on.However,the new techniques are not widely used in China,and it is necessary to carry out a series of clinical practices,which should be carefully selected for IBD patients undergoing minimally invasive surgery.

At present,the technology to predict the response to neoadjuvant therapy with biomakers has been widely used in clinical practice.The approaches of biomarkers detection are various,including immunohistochemistry,detection of serum biomarkers conventional blood tests,gene expression profile analysis,single nucleotide polymorphisms,miRNAs,proteomics analysis.With the development of biotechnology,the technology of biomarkers detection is expected to become effective means in assessment of adjuvant therapy,risk,prognosis and individualization in esophageal cancer treatment.

Objective To assess the effect of fructose sodium diphosphate and alpha-lipoic acid on diabetic peripheral neuropathy. Methods Sixty-six patients with diabetic peripheral neuropathy were randomly divided into two groups, additional to the regular treatment to control blood glucose, 34 patients in the treatment grouptreated with fructse sodium diphosphate 10 g and alpha-lipoic acid 0.45 g daily through intravenous drip for two weeks (3 patients dropped out due to un-tolerance), 32 patients in the control group treated with alpha-lipoic acid 0.45 g dai-ly through intravenous drip for two weeks. All patients were examined on the improvement of symptoms, motor and sensory nerve conduction velocity of the median nerve and nervus peroneus communis before and after the treatment. Results After treatment for two weeks, the overall effect rate in the treatment group was 93.55 % (28/31), which was significantly higher than that in the control group(68.75%,22/32) (P < 0.05). In the treatment group, the motor nerve conduction velocity for the median nerve and nervus peroneus communis was 47.7 (SD:3.8) m/s and 41.6 (SD: 3.3) m/s after treatment, which was significantly higher than that before treatment (42.5 [SD:2.5] and 36.0[SD:2.8] m/s,respectively) (P <0.05). In the control group, the motor nerve conduction velocity for the median nerve and nervus peroneus communis was 43.4 (SD: 2.0) m/s and 39.6 (SD: 3.3) m/s after treat-ment, which was significantly higher than that before treatment (41.9 [SD16.0] and 36.2 [SD: 1.9] m/s, respec-tively) (P < 0.05). In the treatment group,the sensory nerve conduction velocity for the median nerve and nervus peroneus communis was 40.3 (SD: 1.8) m/s and 34.1 (SD: 2.3) m/s after treatment, which was significantly higher than that before treatment (35.2 [SD:2.3] and 28.8 [SD:2.5] m/s,rospectively) (P <0.05). In the control group,the sensory nerve conduction velocity for the median nerve and nervus peroneus communis was 37.7 (SD:1.7) m/s and 30.8 (SD:2.6) m/s after treatment,which was significantly higher than that before treatment (34.8 [SD :3.1] and 27.8 [SD :2.4] m/s, respectively) (P < 0.05). Furthermore, the improvements in the treat-ment group was significantly higher than those of the control group (P < 0.01). Conclusions Fructse sodium si-phosphate combined with alpha-lipoic acid is more effective to treat diabetic peripheral neuropathy than alpha-lipoic acid only.

ObjectiveTo study the feasibility of laparoscopic assisted splenectomy for massive splenomegaly and devascularization in the treatment of patients with cirrhosis and portal hypertension.MethodA retrospective study was carried out on 12 patients who underwent laparoscopic assisted splenectomy and devascularization from October 2003 to January 2010.ResultsThe operation was successfully carried out in eight patients.The remaining four patients were converted to open surgery due to intra-operative bleeding.The mean operation times for the 12 patients and the 8 patients who underwent laparoscopic surgery were 350 min (range,190-470 min) and 313 min (range,190-410 min),respectively.The corresponding mean intra-operative blood losses were 1300 ml (range,200-2200 ml) and 700 ml (range,200-1700 ml),respectively.For the 8 patients who received laparoscopic surgery,flatus were passed 3-5 days after operation,and the postoperative hospitalization was 10-20 days.ConclusionsLaparoscopic assisted splenectomy for massive splenomegaly and devascularization is feasible.It is a treatment option for patients with cirrhosis and portal hypertension.

Objective To clone acidic mammalian chitinase (AMCase) gene and analyze the sequences of the nucleotides and encoded amino acids. Methods Total RNA was isolated from the stomach of BALB/c mouse and the mRNA was reversely transcribed into cDNA. AMCase gene was amplified by polymerase chain reaction and inserted into recombinant clone vector of pMD18-T. Sequence alignment was performed with DNAMAN 4.0 software. Isoelectric point, amino acid composition, signal peptide and transmembrane helices were analyzed with SignalP 3.0 Server and TMHMM Server v.2.0. Results The cloned gene encodes a protein of 473 amino acids with molecular weight of 51.93 kDa and isoelectric point 4.73. Extensive amino acid sequence homology (up to 99.57%) was found when compared with AMCase. Both protein encoded by this cloned gene and AMCase belonged to family 18 chitinase, which was composed of signal peptide (amino acid position 1-21), the catalytic domain (amino acid position 22-391), hinge region (amino acid position 392-425) and chitin binding domain (amino acid position 426-473). There were two mutations of amino acid in the catalytic domain and hinge region with this AMCase mutant. The amino acid of Ala(position 292)was mutated into amino acid of Pro, and the amino acid of Thr(position 404)was mutated into amino acid of Ser. Conclusion This sequence is a mutant of AMCase gene. Identification of the biological characteristics will play important role in the further study of its biological function by molecular biology technique.

Objective:To study the torsional property and rotary fatigue fracture of Smart K files and R reamers made of nickel-titanium alloy. Methods:The torsional property and rotary fatigue fracture behavior of Smart K files and R reamers were evaluated by means of specially-designed torsional device and simulated endodontic root canals system. The instrument surface and the rotary fatigue fractured surface were investigated by optical microscope and scanning electron microscope. Results:Compared with ANSI/ADA specification No.28, maximum torque values of Smart K and R endodontic instrument were higher. Tensile stresses on the outer surface of the endodontic instruments played a dominant role in fracture initiation during rotary fatigue fracture. The rotary numbers corresponding to rotary fatigue fracture decreased with the increase of the instrument size and curvature. Smart K and R endodontic instruments exhibited good ductility. Dimples were found on the fractured surface, and the fatigue fracture was the typical ductile fracture. Conclusion:Smartendodontic instruments have excellent torsional and rotary fatigue fracture resistance properties.
