Objective:To evaluate the effect of nutritional status on postoperative outcomes for patients with gastric cancer. Methods:Data of 353 gastric cancer patients at Xinjiang Medical University Affiliated Tumor Hospital between January 2013 and October 2014 were collected prospectively. Preoperative nutritional status was evaluated using Nutrition Risk Screening 2002 (NRS 2002). Postoperative complication rates were compared among different preoperative nutritional status. Results:On the basis of NRS 2002, the morbidities of patients with and without malnutrition risk were 47.0%(77/164) and 31.2%(59/189), respectively (P=0.002). Among the patients with an NRS score of at least 3, the complication rate was significantly lower in the group with preoperative nutrition than in the group of patients without preoperative nutrition support (P=0.013). NRS 2002 was a significant predictor of postoperative complications (P=0.039, OR=1.634, 95%CI:1.025-2.606) on the basis of multivariable logistic regression analysis. Conclusion:As a nutritional evaluation tool, NRS 2002 may predict postoperative complications for gastric cancer patients.

Chinese Pharmaceutical Journal 2018;53(15):1300-1308
OBJECTIVE: To establish a gradient elution method for determination of related substances of azithromycin for injection. METHODS: Gradient elution was used for the analysis. A C18 (CAPCELL PAK MGⅡ, 4.6 mm×250 mm,5 μm)column was used. The mobile phase A consisted of 0.05 mol·L-1 K2HPO4 solution (pH 8.2, adjusted with 20% phosphoric acid)-acetonitrile (45∶55), and the mobile phase B was methanol. The flow rate was 1.2 mL·min-1, and the detection wavelength was set at 210 nm. The column temperature was maintained at 30 ℃. The gradient elution program was as follows: 0-35 min, A:75%→95%; 35-64 min, A:75%; 64-65 min, A:95%→75%; 65-71 min, A:75%. RESULTS: Azithromycin, near peaks and known impurities were well separated from each other. All acid radicals of azithromycin for injection did not influence the determination of related substances of azithromycin. CONCLUSION: This method is more specific than the exising method for determination of related substances of azithromycin, which can more effectively control the quality of the drug.

Objective To evaluate the efficacy and safety of the bundles of treatment protocol for patients with acute brain injury (ABI) complicated by acute lung injury (ALl)/acute respiratory distress syndrome (ARDS).Methods A total of 83 patients with acute brain injury complicated by ALI/ARDS were randomly divided into experimental group (n =41) and control group (n =42).The control group was treated with the routine bundle protocol while the experimental group was treated with an intensive bundle protocolin addition to the routine bundle protocol.The data was collected,and the effectiveness and safety of the two bundles of treatment protocol were evaluated.Results The results of heart rate (HR),SpO2,and PO2/FiO2 in the two groups showed significant differences before and after treatment.The improvement of PO2/FiO2 in the experimental group occurred earlier and was more significant compared tothe control group,24 hours after treatment.The mechanical ventilation time,ICU stay time,and total hospitalization time for the experimental group were significantly different (P < 0.05) from the control group.The 28-day mortality and morbidity of ventilator-associated pneumonia showed no significant difference (P > 0.05) between the two groups.Conclusion The treatment of acute brain injury complicated by ALI/ARDS by the two bundles of treatment protocol is effective.Compared to the conventional treatment bundles,the intensive treatment bundles can significantly improve oxygenation,and shorten the mechanical ventilation time required,as well as ICU and total hospital stay.

BACKGROUND:Due to special physiological and anatomical location, stability of the spine is very complicated during thoracolumbar fractures. It is difficult to identify the stability of the spine. It should be based on their individual circumstances, to explore more effective internal fixation repair method.
OBJECTIVE:To explore the Cobb’s angle and vertebral height of patients with thoracolumbar fracture and spinal cord compression treated with posterior laminectomy and screw fixation, and compared with anterior laminectomy.
METHODS:One hundred patients with thoracolumbar fracture and spinal cord compression, who were treated in the Panyu District Central Hospital from January 2013 to November 2014, were enroled in this study. The patients were equaly and randomly divided into posterior laminectomy fixation group and anterior laminectomy fixation group. Tactile and sports of American Spinal Injury Association scores, Cobb’s angle and vertebral height were assessed before treatment and 1 month after treatment, and fixation effects were compared between the twogroups.
RESULTS AND CONCLUSION:(1) No significant difference in each index was detected between the two groups preoperatively (P> 0.05). (2) Tactile and sports of American Spinal Injury Association scores, Cobb’s angle and vertebral height were better in the posterior laminectomy fixation group than in the anterior laminectomy fixation group at 1 month postoperatively (P< 0.05). (3) These findings indicated that compared with the anterior laminectomy fixation, posterior laminectomy fixation for thoracolumbar fracture combined with spinal cord compression obtained better outcomes, and could obviously relieve spinal cord compression. Posterior laminectomy fixation isasafe and effective treatment method for thoracolumbar fracture and spinal cord compression.

Objective To investigate the effects of ghrelin on colonic motility in mice.Methods The eflfects of ghrelin on colonic propulsive movement were detected by charcoal suspension pushing test after injection of normal saline and different doses of ghrelin(20,50,100,200 ng/g).The effects of atropine,NG-nitro-L-arginine methylester hydrochloride(L-NAME)or D-Lys3-GHRP-6 on the changes of colonic propulsive movement caused by ghrelin(100 ng/g)were also investigated.In vitro,the effects of different doses of ghrelin(0.01,0.1,1,10μmol/L)on the spontaneous contraction amplitude of proximal colonic circular muscle strips were studied.Results Ghrelin significantly accelerated the colonic propulsive movement in dose-dependent manner,but the efiect was significantly inhibited in the presence of atropine,L-NAME or D-Lys3-GHRP-6(t=10.230,12.560,11.590,P<0.05).Administration of ghrelin significantly increased the contraction amplitude of colonic circular muscle strips.but this effect was inhibited when the colonic circular muscle strips were pretreated by tetrodotoxin.ConclusionsGhrelin can accelerate colonic propulsive movement by activating growth hormone secretagogue receptor of cholinergic excitatory pathways and nitrergic nervous pathways in the enteric nervous system of colon.

Objective To investigate the effects of the intravenous immunoglobulin (IVIG) on the expression of FcγR Ⅱ b and Toll-like receptor 4 (TLR4) in children with Kawasaki disease (KD).Methods 25 children with KD and 15 healthy controls were enrolled in this study.The levels of TLR4 expression on monocytes were assessed by flow cytometry.Real-time PCR was performed to detect the transcription levels of FcγR Ⅱ b,TLR4 signaling molecules(MyD88,TRAF-6,TAK1) and cytokines(IL-1β,IL-6,TNF-α) in monocytes.The concentrations of TNF-α in plasma was determined by enzyme-linked immunosorbent assay (ELISA).Results (1) Compared with healthy controls,the expression of TLR4 and the signaling molecules in the patients were significantly up-regulated but decreased after treatment with IVIG (P<0.05).(2)The levels of FcγR Ⅱb expression from the patients were higher than those from healthy controls,and decreased after treatment with IVIG(P<0.05).(3) The levels of cytokine factor expression such as IL-1β,IL-6 and TNF-α in the patients were found to be higher than those in healthy controls (P<0.05) ; plasma concentrations of TNF-α were significantly elevated during acute KD (P<0.05).(4)There were significantly correlations to follow between FcγR Ⅱb and the levels of cytokine,TLR4 expression in monocytes (P <0.05).Conclusion IVIG can up regulate FcγR Ⅱb expression and down regulate TLR4 expression which might inhibit the inflammatory response.
