Objective:To investigate the clinical and pathological factors of metastasis in patients with oral squamous cell carcinoma (OSCC)and clinical lymph node-negative(cN0).Methods:85 patients of OSCC with cN0 treated in 2008-07 -2013-07 were inves-tigated retrospectively.Results:In the 85 patients 24(28.34%)showed occult metastasis.Patient's gender,lesion location had no im-pact to metastasis(P >0.05),the patient's age,tumor size,growth pattern and histopathologic grade showed significant influence on the metastasis of OSCC(P <0.05).Conclusion:The greater tumor volume,lower differentiation degree and young age are the factors of higher occult lymph node metastasis.Selective neck dissection treatments of OSCC is recommended.

Objective To analyze anemia in patients with chronic heart failure changes in relevant indicators.Methods 48 chronic heart failure patients(observation group)and 48 healthy people(control group).were erolled the peripheral blood red blood cell count(RBC),hemoglobin(Hb),hematocrit(Hct)and other anemia-related indicators were measured.Results The results of the observation group RBC,Hb,Hct,were(3.37 ±0.49)× 1012/L,(103.64±14.33)g/L,(0.31 ±0.08)respectively,the control group were(4.64 ±0.51)× 1012/L,(121.33 ±17.69)g/L,(0.37 ± 0.07),between the two groups were statistically significant(t =4.46、3.06、4.18,P =0.02,0.04,0.04);treatment,symptoms of heart failure in observation group mitigation,RBC is(3.76 ± 0.58)× 1012/L,compared with the control group the difference was significant(t =0.48,P =0.03); observation group Hb,Hct were (123.77 ± 17.26)g/L,(0.37 ± 0.05),and were not significantly different with the amtrol gronp(P =0.06,0.11).Conclusion Elderly patients with anemia associated with heart failure were lower than healthy people,heart failure and anemia had,a significant correlation with aremia.

Objective Aspirin is a non steroidal anti-inflammatory drugs, whether or not which does harm to renal function in the course of using, there is a big debate at home and abroad.In this paper, The aim of this study was to observe the effects of different doses of aspirin on renal function in elderly patients with cardiovascular disease at different ages.MethodsWe Selected a total of 288 patients with cardiovascular disease from January 2014 to March 2016 in Zhejiang Rongjun hospital.There were 288 cases of cardiovascular disease, including 144 cases of normal uric acid, 144 cases with hyperuricemia (including gout).The two groups according to the age of 60 to 70 years, 71 to 80 years old, over 80 years old respectively into three subgroups, each subgroup of 48 cases;Each subgroup was randomly selected without the use of aspirin (0mg/d) and the use of different doses of aspirin (50mg/d, 100mg/d, 150mg/d) for a total of four groups, each which is 12 patients.We detect patients routine blood tests, liver and kidney function, blood urea nitrogen (BUN), blood creatinine (SCR) levels and glomerular filtration rate (GFR) (MDRD) and blood and urine beta 2-microglobulin used aspirin before and used after 6 months and 12 months.ResultsBefore treatment, there were no significant differences in body mass index (BMI), blood pressure, hemoglobin, serum albumin and platelet count between various groups of the same age group.After treatment for 6 and 12 months,Uric acid normal patients and high uric acid patients with 0mg/d, 50mg/d, 100mg/d or 150mg/d dose of aspirin has no statistical difference in BUN, Scr and eGFR, 2-microglobulin Ccr, blood, urine beta 2-microglobulin.ConclusionRegardless of uric acid, different doses of aspirin had no significant effect on renal function in elderly patients with cardiovascular disease, and can be safely used.

Objective To study changes of serum IL-17 and IL-35 levels in patients with heart failure. Methods 60 patients with heart failure (observation group)were selected as research subjects.60 patients accord-ing to different severity were divided into acute period heart failure (34 cases)and stable stage heart failure (26 ca-ses);60 patients graded according to the NYHA standards were divided into 24 cases of heart failure with grade Ⅱ, 20 cases of grade Ⅲ ,16 cases of grade Ⅳ.According to the different primary diseases :expansion cardiomyopathy group (20 cases in group A),the coronary heart disease group (group B,24 cases),hypertensive heart disease group (group C,16 cases).During the same period,42 healthy elderly people in our hospital were selected as control group. The serum IL-17,IL-35 levels were tested,and the serum IL-17,IL-35 levels in patients with heart failure were ana-lyzed.Results Serum level of IL-17 in the observation group was higher than the control group,and the difference was significant [(15.61 ±4.02)pg/mL vs (9.49 ±3.96)pg/mL,t =9.018,P <0.01].Serum level of IL-35 in the observation group was significantly lower than that of the control group,and the difference was significant[(52.78 ± 4.29)pg/mL vs (61.49 ±4.81)pg/mL,t =11.963,P <0.01].The level of serum IL-17 in acute stage of patients with heart failure was higher than that of stable heart failure,and the difference was significant (t =6.278,P <0.01);IL-35 level in serum of patients with heart failure in acute phase was lower than that of stable heart failure,the difference was significant (t =9.529,P <0.01).With the increase in heart failure grade,serum IL-17 level showed a rising trend,and the differences among three groups had statistical differences (F =6.098,P <0.01);serum IL-35 level decreased,and the differences among three groups had statistical differences(F =8.978,P <0.01).The serum IL-17 level of A group was higher than that in B group and C group,there were significant differences (F =6.096, P <0.01),the serum IL-17 level between B group and C group had no statistical difference (t =0.172,P >0.05). The serum IL-35 level of A group was lower than that of B group and C group,there were significant differences (F =8.978,P <0.01),the serum IL-35 level between B group and C group had no statistical difference (t =0.208,P >0.05).Serum IL-17 and serum IL-35 level was negatively correlated (r =-0.429,P =0.009).Conclusion High expression of IL-17 in elderly patients with heart failure,while IL-35 decreased in elderly patients with heart failure, IL-17,IL-35 are closely related to the senile congestive heart failure and the severity of illness.Serum IL-17 is nega-tively correlated with the level of serum IL-35.

Objective To observe the clinical effect of Salmeterol xinafoate and fluticasone propionate powder for inhalation in patients with chronic obstructive pulmonary disease.Methods 70 patients diagnosed with chronic obstructive pulmonary disease from March 2014 to March 2015, were randomly divided into two groups ( n =35 ) .Control group were given basic treatment, observation group was given Salmeterol xinafoate and fluticasone propionate powder for inhalation on the basis of control group , patients were followed up and changes of related indicators wererecorded. Results After treatment one month, serum airway remodeling index b-FGF, TIMP-1 values were (93.86 ±17.36 μg/L, 38.06 ±4.28ng/mL) respectively, more than control group(135.03 ±16.06μg/L, 53.95 ±4.15ng/mL)(P<0.05).After treatment one month, inflammatory markers IL-8, TNF-αwere(7.26 ±1.57 pg/mL, 4.29 ±1.02 ng/L)respectively, were more than the control group (14.27 ±1.71 pg/mL, 8.90 ±1.21 ng/L) (P<0.05).After treatment, the observation group, the total effective rate was 91.43%, higher than 77.14%(P <0.05).Conclusion Salmeterol xinafoate and fluticasone propionate powder for inhalation has good effect in treatment of chronic obstructive pulmonary disease , better than the use of basic treatment alone.

Objective To observe clinical efficacy of probiotics agents in the prevention and treatment of severe pulmonary infection in elderly patients with antibiotic-associated diarrhea (AAD).Methods 60 cases of elderly patients with severe pulmonary infection (more than or equal to 60 years old) were randomly divided into the treatment group ( 31 cases ) and control group ( 29 cases ) , the control group received broad-spectrum antibiotics or using two linked above anti-infection treatment, the treatment group were added with probiotic agent ( lactobacillus complex capsules).The diarrhea, the use of antibiotics and the stool routine, bacteria before and after 5, 10, 15 days of group were observed.Results After 15 days treatment, the number of Escherichia coli in treatment group was lower than that in control group (P<0.05), the number of Bacterium lacticum and Bifidobacterium bifidum in treatment group were higher than those in control group ( P<0.05 ) .The AAD rate in treatment goup was 12.90%, which was lower than 41.38% in control group (P<0.05).There were significant differences in beginning time and duration of diarrhea between two groups (P<0.05). Conclusion The intestinal probiotics reduced induced by antibiotics in elderly patients with severe pulmonary infection , the probiotics agents could redress intestinal flora imbalance, keep the steady state of intestinal flora, and prevent and cure the antibiotic-associated diarrhea.

Objective To explore the regulation and effect factors of arsenic expose and arsenic methylation level, then to provide a reference for study the function of arsenic metabolism in a arsenic poisoning process. Methods A meta-analysis was performed by two researchers. Twenty-five papers satisfying our priori eligibility criteria were included by searching Cochrane library, Pubmed, Springer, Embase and China National Knowledge Infrastructure. Based on the results of heterogeneity, a random or fixed effects model was chosen for the meta-analysis. Results The results showed that the following arsenic metabolites increased (all P<0.01) following arsenic exposure: inorganic arsenic [iAs; standardized mean difference (SMD): 1.07; 95% confidence interval (CI):0.61 - 1.53)], monomethyl arsenic (MMA; SMD: 1.10; 95% CI: 0.81 - 1.40), dimethyl arsenic (DMA; SMD: 2.50;95%CI:1.50-3.69), and total arsenic (TAs, SMD:3.10;95%CI:2.13-4.07). Additionally, the percentages of iAs (iAs%; SMD: 1.00; 95% CI: 0.60 - 1.40) and MMA (MMA%; SMD: 0.49; 95% CI: 0.21 - 0.77) also increased, while the percentage of DMA (DMA%; SMD: - 0.55; 95% CI: - 0.80 - - 0.31) decreased (P<0.01). The primary methylation index (PMI; SMD: - 0.57; 95% CI: - 0.94 - - 0.20), and secondary methylation index (SMI;SMD: - 0.27; 95% CI: - 0.46 - - 0.09) decreased (all P< 0.01). Compared to female, male had higher MMA%(SMD:0.44;95%CI:0.35-0.52), lower DMA%(SMD:-0.33;95%CI:-0.38--0.28) and SMI (SMD:-0.36;95%CI:-0.53--0.19). The smoker had higher MMA%(SMD: 0.22; 95%CI: 0.07 - 0.37) and lower DMA%(SMD:-0.16;95%CI: - 0.26 - - 0.05). The drinker had higher MMA% (SMD: 0.17; 95% CI: 0.07 - 0.27) and lower DMA%(SMD:-0.24;95%CI:-0.39--0.10). The older people had higher MMA%(SMD:-0.23;95%CI:-0.40--0.06). In addition, the body mass index may influence the percentages of MMA (SMD: - 0.18; 95% CI: - 0.31 - - 0.04, P < 0.01). Conclusion Arsenic exposure, smoking, drinking, and older age can reduce the capacity of arsenic methylation. Arsenic methylation is more efficient in women than in men.

Questionnaire-based survey, physical examination, and blood testing were conducted according to cluster random samplings in Kazakh residents in Xinjiang.2 760 samples were collected to analyze the association of different strata of waist circumference and clustering of metabolic syndrome (MS) components.Accoding to International Diabetes Federation standard, the prevalence of ≥1and ≥2 components of MS showed increasing trend with the increase of waist circunference, and odds ratio of clustering of MS components also increased significantly.The distance of receiver operating characteristic curve was the shortest and the prevalence of MS was 22.1% ;22.4% in men, and 21.9% in women;when the waist circumference was ≥91 cm for men, and ≥88 cm for women.

Objective To investigate the association of lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms with metabolic syndrome. Methods PCR-RFLP was used to detect lipoprotein lipase Hind Ⅲ and S447X genotypes in 401 subjects(including 201 controls, 200 metabolic syndrome patients). Results ( 1 ) The levels of waist circumference ( WC ) , hip circumference ( HC ) , waist-to-hip ratio ( WHR ) , body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure ( DBP) , total cholesterol ( TC) , triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and fasting plasma glucose (FPG) were significantly different between metabolic syndrome group and control group (all P< 0.05). (2)The frequencies of H+H+ genotype,H+allele,SS genotype, and S allele for metabolic syndrome were all significantly higher than those for controls( H+H+ genotype:66. 5% vs 54.2% ,P=0.012; H+ allele:78.0% vs 71.4%, P=0.031;SS genotype:89.5% vs 77. 1% , P = 0.001; Sallel:94.5% vs 87. 56% , P = 0.001). (3) The levels of WC, HC, WHR, BMI, SBP, DBP, TG, LDL-C, and FPG in H + H-/H-H- genotype were significantly lower than those in H+H+ genotype, HDL-C was significantly higher than that in H+H+ genotype ( all P<0. 05). The levels of WC, HC, WHR, BMI, SBP, DBP, TC, TG, and FPG in SX/XX genotype were significantly lower than those in SS genotype, HDL-C was significantly higher than that in SS genotype ( all P< 0.05). (4)Multi-way logistic regression analysis suggested that risk factors for metabolic syndrome were smoking, drinking, and SS genotype (OR value was 4.289,2.268, and 2. 597, respectively ). (5) Result of interaction analysis among different factors indicated that the risk for metabolic syndrome in smoker with SS genotype was 3. 996 times of non-smokers with SX/XX genotype. Conclusions The lipoprotein lipase gene S447X polymorphism is associated with metabolic syndrome risk in Kazakh, and SS genotype and S allele may serve as genetic risk factors of metabolic syndrome, H + H-/H-H- and SX/XX genotypes yield beneficial effect for lipid and blood pressure. SS genotype and smoking may exist additive effect.

Objective: To observe the characteristics of serum homocysteine (Hcy) distribution and the epidemiological characteristics of high serum level of Hcy (HHcy) in Kazakh population.
Methods: The stratiifed cluster random sampling method was used to investigate 1003 kazakh individuals in Xinyuan county of Xinjiang including 433 male and 570 female, and they were individuals into 5 age groups:①(25-34) years, n=333,②(35-44) years, n=306, ③(45-54) years, n=230, ④(55-65) years, n=90, ⑤>65 years, n=44.
