Objective To explore the effects of nutritional intervention on body composition,blood biochemical parameters and blood pressure of overweight adults with metabolic syndrome.Methods Forty overweight adults with metabolic syndrome (body mass index (BMI) > 28.0 kg/m2,waist circunference ≥85 cm(for male)or ≥80 cm(for female))participated in this investigation.Changes of serum lipid profiles,blood glucose,blood pressure and other indicators were compaired before and after 2-months'intervention.SPSS 18.0 Software was used for data analysis.Results After two rnonths' nutritional intervention,body weight,body fat,BMI,visceral fat area and waist hip ratio were significantly improved(t =17.02,11.07,5.11,10.35,9.58 ; P < 0.05).The glutamic-pyruvic transaminase,glutamic-oxalacetic transaminease,cholesterol,triacylglycerol,fasting blood-glucose,systolic blood pressure and diastolic blood pressure were also significantly improved after nutrition intervention(t =2.87,2.91,3.33,2.24,2.56,5.74,6.99 ;P < 0.05).Conclusion Nutrition intervention may contribute to improved levels of blood pressure,blood glucose and serum lipid profiles of obesity individuals through body weight and body fat control and lead to reduced insulin resistance caused by obesity.

Purpose To explore the value of spectral CT imaging in differentiating pancreatic carcinoma and mass-forming pancreatitis, and to improve the preoperative diagnosis accuracy. Materials and Methods The dual-phase spectral CT imaging data in patients with pathology-proven pancreatic carcinoma (n=62) and mass-forming pancreatitis (n=30) were retrospectively analyzed. At 40-140 keV (with 10 keV increment), the mean CT values, energy spectrum curves and iodine concentrations were measured and compared between pancreatic carcinoma and mass-forming pancreatitis in arterial phase and portal venous phase. Results The mean CT values of mass-forming pancreatitis at 40-140 keV were higher than pancreatic carcinoma in both arterial phase and portal venous phase with significant difference (t= -7.349- -4.810, P<0.05; t= -6.760- -5.496, P<0.05). The energy spectrum curves were significantly different between pancreatic carcinoma and mass-forming focal pancreatitis, especially at 40-70 keV. The iodine concentrations of pancreatic carcinoma were lower than mass-forming pancreatitis in arterial phase and portal venous phase with significant difference (t=-28.577, P<0.05; t= -28.451, P<0.05). Conclusion Pancreatic carcinoma and mass-forming pancreatitis can be differentiated by measuring the CT value at different energies, energy spectrum curves and iodine concentrations.

Objective To study the impact of lung volume reduction surgery on inflammatory factors, pulmonary function and quality of life in patients with severe chronic obstructive pulmonary emphysema. Methods 57 cases patients with severe chronic obstructive pulmonary emphysema received lung volume reduction surgery from May 2009 to December 2013 were divided into observation group 32 cases and control group 25 cases, the control group were given open chest surgery, the observation group received video-assisted thoracoscopic surgery. Then compare the operation indicator, serum inflammatory factor content, pulmonary function and life quality score between the two groups. Results Operation indicators: Observation group: Intraoperative blood loss, thoracic drainage, hospital stay were significantly lower than that in control group (P< 0.05); Inflammatory factor: 3 d after surgery, observation group serum TNF-α, IL- 6, IL- 1 content were significantly lower than that in control group (P<0.05);Pulmonary function: 12 months after surgery, there were no statistical difference of FEV1, TLC, RV between two groups (P>0.05); SGRQ score: 12 weeks after the surgery, observation group respiratory symptoms, activity ability, disease im﹣pact, SGRQ total score were significantly lower than the control group (P< 0.05). Conclusion Video assisted tho﹣racic surgery helps to reduce surgical trauma, and alleviate inflammatory reaction, then improve the quality of life.

AIM: The purpose of this study was to investigate the role of interleukin-4 (IL-4) in the development of periodontitis in mice by low dosage of Trichinella spiralis (T. spiralis) infection.METHODS: Twenty-seven male Kunming mice in specific pathogen free grade were randomly divided into three groups: (1) the normal control group;(2) the experimental periodontitis group, which was produced by ligature of braided silk around the first maxillary molar, and was inoculated with putative periodontopathic bacteria;(3) the periodontitis with T. spiralis infection group. The mice were sacrificed at the end of 1, 3 and 5 weeks. The probing depth (PD) was measured before the mice were euthanized. The histological change of periodontal tissues was observed under the microscope after the samples were stained with hematoxylin and eosin. Furthermore, the serum level of IL-4 was determined by ELISA. RESULTS: (1) The serum level of IL-4 in T. spiralis-infected group was significantly higher than that in experimental periodontitis group (P<0.01). (2) The PD in T. spiralis-infected group was significantly lower than that in experimental periodontitis group (P<0.01). (3) Only a mild inflammatory response was observed in T. spiralis-infected animals. CONCLUSION: T. spiralis infection upregulates IL-4 expression and attenuates periodontitis in mice.

Objective To investigate the effects of hippocampal neurogenesis in spatial learning and memory,especially in spatial long-term memory.Methods Totally 24 wistar rats were randomly divided into two groups:normal control group (NC group,n =12) and irradiation group (IRR group,n =12).We use low-dose irradiation at subgranular zone to inhibit adult hippocampal neurogenesis and new neurons were investigated by 5-Bromo-2-deoxyUridine/neuron specific nuclear protein double-labeling.Four weeks after irradiation,Morris water maze,including navigation test and space exploration assay,was used to detect spatial leaming and memory.Then,in the day 8 and day 15 after the navigation test,space exploration assay was repeated to detect spatial long-term memory.The expression levels of postsynaptic density protein 95 and synaptophysin were evaluated using western blot and real-time quantitative PCR.Results Hippocampal neurogenesis was inhibited by low dose irradiation(2.80 ± 0.44 vs 23.50 ± 1.12,t =20.21,P < 0.01).After the inhibition,the escape latency did not change,while the time spent in target quadrant was significantly declined in the day 2((14.76 ±.2.04) s vs (20.47 ± 1.29) s),day 8((11.95 ± 1.34) s vs (19.52±1.43) s)and day 15((11.79 ±1.35) s vs (21.58 ±1.07) s) after the navigation test (t=2.45,P<0.05; t =3.76,P<0.01; t =5.39,P<0.01).The postsynaptic density protein 95 and synaptophysin expressions were significantly decreased in IRR group.As to the RNA levels,there was also a significant difference between the two groups.Conclusion Hippocampal neurogenesis in the dentate gyrus plays an important role for the formation of spatial long-term memory.

Objective To explore the design and application of the multifunctional treatment beds on patients′ position compliance and comfort after intraocular retinal reattachment surgery. Methods Eighty-six patients needing special position nursing after intraocular retinal reattachment surgery were randomly divided into experiment and control groups. The former received the special multifunction treatment beds while normal ward beds were used for the control patients . The position compliance , comfort and the complications were observed one month after surgery. Result The position compliance and the degree of comfort in the experiment group were significantly better than those in the control group and the complication rate was significantly lower than that of the control group (all P<0.05). Conclusion The special multifunction treatment beds can be effective in increasing the patients compliance in positions and compliance as well as reducing postoperative complications and increasing the operation success rate.
