BACKGROUND:The development of spinal non-fusion technology promoted movement function protection of adjacent segment and operating segment. In the treatment of cervical spondylosis surgery, non-fusion technology has been widely carried out. For middle-aged patients with cervical spondylosis, the demand for spinal joint movement function is high. Non-fusion technology can improve the postoperative quality of life and slow down the risk of adjacent segment degeneration. OBJECTIVE:To evaluate the clinical efficacy of anterior cervical different implant materials (fusion or non-fusion) in the treatment of single segment of the intervertebral disc degeneration of cervical spondylosis in middle-aged patients. METHODS:This study enrol ed 10 cases of single segmental radiculopathy and cervical myelopathy after cervical intervertebral disc replacement from June 2011 to June 2013. Simultaneously, 10 cases were randomly selected from patients with anterior interbody fusion as the control group. Before treatment, at 1 and 3 months, and 1 year after treatment, changes in range of motion of cervical vertebra were observed using imaging results. Therapeutic effects were assessed using Japanese Orthopaedic Association Scores, Visual Analog Scale and The Neek Disability Index in both groups. RESULTS AND CONCLUSION:Al patients did not suffer from incision fat liquefaction, infection and delayed healing, and had finished fol ow-up for more than 1 year. Results revealed that Japanese Orthopaedic Association Scores and Visual Analog Scale scores were improved at 1 and 3 months, and 1 year after treatment (P<0.05), and no significant difference was detected between the two groups (P>0.05). In the analysis of range of motion of cervical vertebra and The Neek Disability Index, there were significant advantages in non-fusion treatment group (P<0.05). For middle-aged patients with cervical spondylosis, due to its life demand for neck mobility, the repair program of non-fusion cervical intervertebral disc replacement has a clear advantage.

AlM: To investigate the effect of exogenous peroxisome-proliferator-activated receptor-γcoactivator-1α ( PGC-1α) on vascular endothelial growth factor ( VEGF) expression in human retinal vascular endothelial cells ( HRVEC) .METHODS:Recombinant PGC-1α protein was added to HRVEC, and no recombinant PGC-1α protein was added to HRVEC as control group. After 24h of incubation, two groups of cells were then placed into a normoxic ( 20%O2 ) or hypoxic ( 1% O2 ) environment for another 16h. The expression of VEGF mRNA and protein were detected by real - time PCR, ELlSA and immunofluorescence cytochemistry.RESULTS: VEGF mRNA and protein levels in the cells were significantly increased by recombinant PGC - 1αprotein both under normoxia and hypoxia conditions as compared with control groups (P<0. 01).CONCLUSlON: PGC-1α can upregulate the expression of VEGF in HRVEC under normoxia and hypoxia conditions.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease. The prevalence of NAFLD is increasing year by year in the world, which seriously threaten the public health. The pathogenesis of NAFLD is complex, and there is no specific treatment for NAFLD. Natural-derived compounds have the characteristics of multi-target and multi-mechanism, which can improve the curative effect and reduce the toxic and side effects by regulating multiple factors of the disease. They are ideal drugs for treating complex diseases and have unique advantages in improving NAFLD. However, low intestinal absorption, poor bioavailability, and single medicine efficiency limit the utilization of many compounds, and further drug development and clinical application are challenging. This paper reviews the research progress of natural-derived compounds in the prevention and treatment of NAFLD in recent years, analyzes the existing problems, and discusses the improvement strategies, so as to provide reference for related research.

Objective To evaluate the possible factors that may influence the resting energy expenditure (REE) in patients with newly diagnosed esophageal cancer. Methods Totally, 40 patients with newly diagnosed esophageal cancer were prospectively collected from November 2008 to June 2009 in Xinhua Hospital. Nutritional risk screening 2002 (NRS 2002) was performed. REE and body composition were measured using indirect calorimetry and bioeletrical impedence method, respectively. Results Twenty-seven (67.5%) patients were found with nutrition risk, and NRS score was negatively correlated with prealbumin ( r = - 0.444, P = 0.004) and albumin levels (r = - 0.386, P = 0.014). Measured REE and predicted REE values were ( 6770 ± 1360) and (6021 ± 841 ) kJ/d, respectively (P ＜ 0.001 ). Among all 40 patients, 57.5% of them were hypermetabolic,30.0% were normal, and 12.5% were hypometabolic. Stepwise linear regression analysis showed that fat free mass was the only significant determinant variable for REE (P ＜ 0.001 ). Conclusion Fat free mass is a factor than can influence the energy metabolism in patients with newly diagnosed esophageal cancer.

Protamex,flavorzyme and neutrase were used for bienzyme hydrolysis of Mytilus edulis.Protamex and flavorzyme were determined as the optimal hydrolases by analysis of hydrolysis effects.After bienzyme hydrolysis,ester forming yeast fermentation was used to prepare seasoner.The effects of fermentation of single or compound strains on the value of FAN were detected by formaldehyde titration method.The results showed that the value of FAN was 0.65% when the conditions of ester forming yeast 1274 were as follows:inoculation volume 5%(v/v),fermentation temperature 28℃ and culture time 72h after bienzyme hydrolysis;the value of FAN was 0.78% when the hydrolytic solution was fermented by compound strains including ester forming yeast 1274 and 1202 under the same fermentation conditions.After fermentation of ester forming yeast,the seasoner gave a full-bodied smell of ester with fermentation flavour.
