Objective: To examine the causal relationships between obesity, peripheral blood lipid indicators and non-small cell lung cancer (NSCLC) using Mendelian randomization (MR) method, so as to provide the basis for developing NSCLC prevention and control strategies. Methods: Genetic variation data of three obesity evaluation indicators, including body mass index (BMI), body fat ratio (BFR) and waist-to-hip ratio (WHR), and seven peripheral blood lipid indicators, including triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB) and lipoprotein a [LP (a)] were collected through genome-wide association studies (GWAS) and related public databases. Potential causal relationships between obesity, peripheral blood lipid indicators and NSCLC were analyzed using inverse-variance weighted (IVW) method and multivariable MR analysis upon a random effect model. Heterogeneity and horizontal pleiotropy of instrumental variables were evaluated using Cochran's Q test and MR-Egger regression. Results: There was statistically association between BMI with NSCLC (OR=1.256, 95%CI: 1.087-1.451); there were no statistically associations between BFR, WHR, seven peripheral blood lipid indicators and NSCLC (all P>0.005). There was heterogeneity in the association between BMI, BFR, WHR, TG, HDL-C and NSCLC (all P<0.05); no horizontal pleiotropy of instrumental variables was found (all P>0.05). There was no statistically association between BMI and NSCLC after adjusting BFR (OR=1.367, 95%CI: 0.878-2.128); there was still statistically association between BMI and NSCLC after adjusting WHR and peripheral blood lipid indicators (both P<0.05). Conclusions The increase of BMI is associated with the increased risk of NSCLC incidence. BFR may be a potential influencing factor for the association between BMI and NSCLC.

Objective To design an anatomic locking plate for the posterior malleolus using 3D reconstruction CT of the ankle joint and software Mimics.Methods The CT data of 20 normal ankles were imported into software Mimics in.dicom format for 3D reconstruction of the ankle joint.The angles of posteromedial and posterolateral varus,the twist height on the sagittal plane and the height of safe screw placement zone,the width of the posterior malleolus were measured for the posterior malleolus.After the anatomic locking plate was designed using the anatomic data measured and software Ungraphics NX5.0,it was 3D printed in a proportion of 1:1.Next,the model plate was tested and evaluated in 15 fresh cadaveric specimens of the ankle all the soft tissues of which were removed to fully expose the bony structure of the posterior malleolus.Results The anatomic measurements showed that the angles of postemmedial and posterolateral varus increased gradually towards the medial and lateral sides along the central axis of the posterior malleolus while the twist height reduced from the lateral to the medial side,and that the width of the posterior malleolus increased gradually from the superior to the inferior.It was found that after placement in the 15 fresh cadaveric specimens the anatomic model plate fit the posterior malleolus very well,fulfilling all the designed requirements for the anatomic locking plate for the posterior malleolus.Conclusion A novel anatomic locking plate for the posterior malleolu has been successfully designed and manufactured using 3D reconstruction CT of the ankle joint,software Mimics and 3D printing.

This research is for the purpose of comparative analysis of the microbial flora structure in the chilled beef with no packing and cling film, which under the same terms of sale. It was used the V3 area fragment of 16S rDNA to carry on PCR-DGGE, Meanwhile used the 16S rDNA sequence to analysis the microbial flora structure of the two samples, according to the technology of clone .The research discovered that the flora structure displays a biggish difference; there was 6 OTU in the chilled beef with cling film, mainly was that Lactococcus(28%), Lactobacillus (26%), Carnobacterium(18%) and Brochothrix (10%); but there was 18 OTU in the chilled beef with no packing, mainly was that Lactococcus(28%), Brchothrix(18%), Acinetobacter (11%). The result indicates that cling film played a certain inhibitory action regarding the Staphylococcus as well as the cold pole bacteria and such bacterium. And it can provide a certain theory ba-sis for the meat processing in the department of microorganism’s control.

It is used the method of pure culture,Selected 32 strains,which were obvious difference in the shape,color and so on common characteristic,From the chilled beef with no packing and cling film on sale in this research;and it was included 12 strains from the chilled beef sample packed with cling film;20 strains from the chilled beef sample with no packing.Simultaneously selected 4 strains which were predominant in each bacterium from the two samples to conduct the further research,8 strains serial numbers are:S01～S08,S01～S04 from the chilled beef sample with no packing;S05～S08 from the chilled beef sample packed with cling film.Through ARDRA(Amplified ribosomal DNA restriction analysis) as well as 16S rDNA to clarify the bacterium's classified status.The physiological and chemical tests were done to determine the various bacteria respective genus.The experiment indicated:S01 is Pseudomonas putida;S02 is Shewanella cincia stain;S03 and S05 are the same Shewanella putrefaciens;S04 is Stenotrophomonas mal-tophilia;S06 is Psychrobacter;S07 is Staphylococcus sciuri;S08 is Microbacterium-laevaniformans.It was proved that two samples altogether have the same predominant bacterium.It can provide certain theory basis for the chilled meat processing craft as the preliminary investigation in the cultured microorganism situation in two samples.

Objective: To observe the effect of acupuncture on serum peptide YY (PYY) and nesfatin-1 in obese patients with insulin resistance. Methods: Ninety-eight obese patients with insulin resistance were divided into a control group and an observation group by the random number table method, with 49 cases in each group. The control group received exercise and dietary interventions, and the observation group received additional acupuncture treatment to the exercise and dietary interventions. The body mass index (BMI), body fat percentage, fasting insulin (FINS), fasting plasma glucose (FPG), homeostasis model assessment for insulin resistance (HOMA-IR), triglyceride (TG), total cholesterol (TC), and serum PYY and nesfatin-1 levels were compared before and after treatment. The efficacy was evaluated after treatment. Results: The total effective rate was significantly higher in the observation group than in the control group (P<0.05). After treatment, the BMI, body fat percentage, and serum TG and TC levels decreased significantly in both groups (P<0.05), and were significantly lower in the observation group than those in the control group (P<0.05). The FINS, FPG, HOMA-IR, and serum PYY and nesfatin-1 levels of the control group were not significantly changed after treatment (P>0.05). The FINS, FPG and HOMA-IR of the observation group decreased significantly after treatment (P<0.05), and were lower than those in the control group (P<0.05). The serum PYY and nesfatin-1 levels of the observation group increased significantly after treatment (P<0.05), and were higher than those in the control group (P<0.05). Conclusion: Based on exercise and dietary interventions, acupuncture is effective for obese patients with insulin resistance. It can reduce the BMI, body fat percentage, blood lipids, blood glucose, and serum insulin levels and improve insulin resistance. The action may be associated with the up-regulation of serum PYY and nesfatin-1.

Objective To investigate the traditional Chinese medicine ( TCM) syndromes of rheumatoid arthritis ( RA) by studying the Chinese medical patterns,and analyze the correlations of different indicators and related syndromes. Methods The questionnaires were designed according to clinical epidemiological theories. The data were collected and analyzed by multivariate statistical methods. Results The TCM symptoms of the 401 cases of RA were concluded into 3 common factors,that is,cold,heat and deficient. Their syndromes were sub-classified as 6 groups: cold syndrome,heat syndrome,deficiency,cold heat complex,deficient cold and asthenic fever. Statistical analysis showed that there were significant differences in health assessment questionnaire ( HAQ) ,platelet ( PLT) ,rheumatoid factor ( RF) ,anti-keratin antibody ( AKA) among these 6 TCM syndromes ( P
