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: To evaluate the effect of simvastatin on the left ventricular mass in patients with essential hypertension (EH). METHODS: 50 patients with hypertension without severe complication were randomly divided into two treatment groups: combination treatment group and hydragogue group, and 25 normal subjects without any treatment were taken as the control. The 25 patients in combination treatment group were given simvastatin and hydragogue for 12 weeks while the other patients in hydragogue group were given hydragogue during the same time. The left ventricular mass was examined from ultrasonography in all patients before and after treatment. RESULTS: The left ventricular mass index (LVMI) was higher in the two treatment groups of patients (133.61±31.02, 118.04±39.62 g·m-2) than that in the control group (88.79±22.73 g·m-2) before treatment (P<0.01, 0.0001, respectively) while the blood pressure was higher. There was no significantly difference in age, serum concentrations of total cholesterol or triglyceride, sugar and blood pressure between the two treatment groups and the control group (P>0.05). There was no significant difference in all variables between the two treatment groups before treatment. After treatment, the LVMI was decreased (133.61±31.02 vs 91.07±16.01 g·m-2, P<0.01) in the combination treatment group while there was no significant change in LVMI in the hydragogue group compared with the control group. The blood pressure in the two treatment groups was decreased to the normal. Compared with hydragogue group, the change of LVMI was higher in the combination group though the serum concentrations of total cholesterol, triglyceride or sugar were not significantly different. No significant change in serum concentrations of total cholesterol, triglyceride or sugar was found during treatment in the two groups. The change of LVMI did not correlate with the change of blood pressure, serum concentrations of total cholesterol , triglyceride or sugar in the combination treatment group(P>0.05). CONCLUSION: Being independent of the changes of serum concentrations of total cholesterol, triglyceride or sugar and blood pressure, simvastatin can inhibit the increase of left ventricular mass in patients with essential hypertension.

Objective To observe effect of environmental enrichment on the learning and memory ability and the expressions of hypoxia inducible factor 1α (HIF-1a) and vascular endothelial growth factor (VEGF) in rats with chronic cerebral hypoperfusion.Methods A total of 40 rats were randomly divided into 3 groups: bilateral vascular occlusion (2VO) of the common carotid arteries group (n=14, 2VO group), 2VO + enriched environment (EE) group (n=14, 2VO+EE group) and sham group (n=12, SHAM group).Morris water maze, novel object recognition test, real-time reverse transcription-polymerase chain reaction (real-time RT-PCR), immunohistochemistry methods and Western blotting were used to detect changes in learning and memory ability of rats and HIF-1α and VEGF expression levels in hippocampus.Results Morris water maze showed that the escape latency was longer in the 2VO group than in the SHAM group at 3, 4 and 5 day during the training (all P＜0.05), while the 2VO+EE group spent significantly less time in finding the platform as compared with the 2VO group at 4 and 5 day (both P＜0.05).The time for space exploration in target quadrant was less in 2VO group than in SHAM group (P＜0.05), while it was longer in 2VO +EE group than in 2VO group (P＜0.05).Novel object recognition test showed that the 2VO operation impaired the priority index (PI) of time spending at exploring the novel object (P＜0.05), and environmental enrichment could improve the PI in 2VO group (P＜0.05).The real-time RT-PCR and Western blotting showed that the HIF-1α mRNA expression was higher in 2VO group than in SHAM group (P＜0.05).The VEGF mRNA and protein expressions were higher in 2VO+EE group than in 2VO group (both P＜0.05).The expression of HIF-1α in hippocampal CA1 area was higher in 2VO group than in SHAM group (P＜0.05).Conclusions Environmental enrichment can alleviate the damages of spatial and non-spatial learning and memory ability which are caused by chronic cerebral hypoperfusion.And HIF-1α and its downstream gene VEGF may be involved in the restoration of cognitive function by enriched environment.

Objective To observe the effects of Radix Angelica Sinensis ( RAS) on depression be-havior and cytokines,TNF-αand IL-6,in the hippocampus and prefrontal cortex of depression model rats in-duced by chronic unpredictable mild stress ( CUMS) .Methods 32 adult male rats weighting 140-160 g were randomly divided into 4 groups: Control,CUMS,CUMS+fluoxetine and CUMS+RAS groups.CUMS procedure went on 5 consecutive weeks and during the last 3 weeks the rats in CUMS+fluoxetine and CUMS+RAS groups were taken RAS or fluoxetine via intragastric administration.After 5-week CUMS procedure, rats were subjected to sucrose preference test,forced swimming test and open field test.After behavioral tests were finished,all rats were anesthetized with 10%chloral hydrate (350 mg/kg,intraperitoneal injection) and then decapitated.The hippocampus and prefrontal cortex of rats were separated and ELISA was used to detect the expression of TNF-αand IL-6 in these regions.Results Comparing with control rats, rats exposed to CUMS showed decreased sucrose preference ratio((42±15)%),prolonged immobility time ((68.28±16.50) s),decreased crossing numbers (31.25±21.56) and increased TNF-α((206.14±30.53)pg/ml) and IL-6 ((369.51±103.81)pg/ml) expression in hippocampus and TNF-α((199.33±25.67)pg/ml) and IL-6 ((347.74±81.04) pg/ml) expression in prefrontal cortex ( P<0.01).However,RAS treated rats reversed the behavioral changes such as sucrose preference ratio((66±21)%),immobility time ((32.53±10.26)s) and crossing numbers ( 83.00 ±23.25 ) , meanwhile reduced TNF-α( ( 53.42 ±12.43 ) pg/ml ) and IL-6 ((93.84±13.19)pg/ml) expression in hippocampus,TNF-α((57.58±8.33)pg/ml) and IL-6((91.18± 17.37) pg/ml) expression in prefrontal cortex among stress rats ( P<0.01) .Conclusion RAS can amelio-rate CUMS induced depression behaviors of rats through regulating hippocampus and prefrontal cortex cyto-kines ( TNF-α,IL-6) .
