Objective To analyze the main clinical features and impact factors of simple renal cyst (SRC), and to provide evidence for the future prevation and cure of simple renal cysts.Methods In this crosssectional study,a total number of 91 433 participants(aged 18-98 years old) were included who underwent health examinations during 2012-2014.The main life styles and clinical features of each participants were recored,and blood biochemistry test, urinanalysis and renal ultrasonography were performed.Results The prevalence of SRC was 2.70％ (2 465 subjects were diagnosed by ultrasonography).It was higher in men than women(2.95％ vs.1.68％, P =0.00), which was increased with the increasing of age (respectively 0.37％, 0.57％, 1.30％ ,2.69％ ,4.46％ and 6.91％ in the group of ≤29year,30-39 year,40-49 year,50-59 year,60 -69 year and ≥70 year,P＜0.01).The maximum diameter of simple renal cysts were (2.6±1.7) cm.Age,rate of men, body mass index, glucose, total cholesterol, creatinine, urea nitrogen, and urinary protein positive rate, kidney stone prevalence were higher in SRC group(respectively (61.11±11.24)year vs.(51.37±13.72) year, 87.59％ vs.79.88％, (25.27 ± 3.19) kg/m2 vs.(24.97 ± 3.35) kg/m2, (6.09 ± 2.08) mmol/L vs.(5.70 ± 1.85) mmol/L, (5.11 ± 1.54) mmol/L vs.(5.02 ± 1.37) mmol/L, (90.71 ± 34.84) μmol/L vs.(80.72 ±28.04) μmol/L, (6.03±3.60) mmol/L vs.(5.55±5.15) mmol/L,7.46％ vs.4.25％ ,7.06％ vs.1.28％ ,P ＜0.01) ,but glomerular filtration rate, triglycerides, rate of like salty, drink, smoke was lower than the group withoutSRC((79.01±19.89) ml/(min· 1.73 m2) vs.91.74±21.8 ml/(min · 1.73 m2),(1.57±1.48) mmol/L vs.(1.69± 1.82) mmol/L, 4.38％ vs.7.94％, 22.68％ vs.30.75％, 24.91％ vs.30.97％;P＜ 0.01).But,there was no difference between these two groups in serum uric acid ((309.16± 85.79) μmol/L vs.(312.38±91.22) μmol/L,P＞0.05).SRC as a dependent variable of multivariate log regression analysis.The result showed the OR of age, gender, fasting blood glucose, urea nitrogen, glomerular filtration rate, positive urine protein,kidney stone were respectively 1.040, 1.862, 1.035, 1.005,0.982, 1.254, 4.526, 95％ CI =1.037 -1.045,1.643-2.110,1.017-1.053,1.000-1.010, 0.980-0.984, 1.068-1.473,3.812-5.374;P ＜0.01).While the OR of multiple SRC was 0.43,95％ CI: 0.210-0.867 (P＜0.05) , when kidney stone as a dependent variable.Conclusion Old-age males are high risk population of catching SRC.Kidney stone and positive urine protein are important risk factors of SRC.Meanwhile kidney stone more easily induce single and small SRC.SRC is a key risk factor to induce renal function decrease.Therefore, GFR is a sensitive index of renal disfunction that induced by SRC.

Objective To explore the clinical effect of psychological rehabilitation on dysphagia with cognitive and psychological disorders post stroke. Methods 120 stroke patients with dysphagia complicated with cognitive and psychological disorders were divided into experimental group (n=60) and control group (n=60). Both groups received neurological routine medical treatment, swallowing function rehabilitation training, feeding training and low-frequency electrical stimulation. Cognitive and psychological therapy was additionally used in the experimental group. Both groups were assessed by Kubota DrinkingWater Test, Mini-Mental State Examination (MMSE), Hamilton Rating Scale for Depression (HAMD) and Hamilton Rating Scale for Anxiety (HAMA). Results 1 month after intervention, the score of Kubota Drinking Water Test improved significantly in both groups, and was higher in the experimental group than in the control group (P<0.001).The rate of clinical improvement was higher in the experimental group than in the control group (P<0.01). The scores of MMSE increased significantly in the experimental group (P<0.001). The scores of HAMD and HAMA decreased significantly in the experimental group (P<0.01). Only the scores of HAMA decreased in the control group (P<0.05). Conclusion Swallowing function rehabilitation training combined with cognitive and psychological therapy may facilitate to improve the cognitive function and psychological state and swallowing function for dysphagia with cognitive and psychological disorders post stroke.

OBJECTIVE:To explore the effects of early treatment with mouse nerve growth factor on the wound healing in aged patients with electric burn. METHODS:78 elderly patients with electric burn were divided into control group and observation group by random number table method,with 39 cases in each group. Control group was given routine method for electric burn, and observation group was additionally given Mouse nerve growth factor for injection 30 μg dissolved in 2 ml 0.9% Sodium chlo-ride injection within 24 h,im,qd,on the basis of control group. Treatment course of 2 groups lasted for 2 weeks. Clinical effica-cies of 2 groups were compared as well as VAS score before treatment,3,5,7 days after treatment. The survival rate of skin flaps and the rate of wound healing 3,5,7 days after treatment,the recovery of wound scar,the value of wound blood perfusion,the time of complete wound healing and the occurrence of ADR were also compared. RESULTS:The total effective rate of observation group(94.9%)was significantly higher than that of control group(66.7%),with statistical significance(P<0.05). 3,5,7 days after treatment,VAS score of observation group was significantly lower than that of control group,and the survival rate of skin flaps and the rate of wound healing were significantly higher than those of control group,with statistical significance(P<0.05). Af-ter treatment,VSS score of observation group was significantly lower than that of control group,while the value of wound blood perfusion was significantly higher than that of control group;the time of complete wound healing was significantly lower than that of control group,with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Early treat-ment with mouse nerve growth factor for elderly patients with electric burns can effectively lower the VAS and VSS score,improve the survival rate of skin flaps and the rate of wound healing,increase the value of wound blood perfusion and shorten the time of complete wound healing with good clinical efficacy and safety.

Objective To prospectively investigate the association between serum uric acid concentration and the risk of brain infarction in Chinese adults.Methods In this prospective cohort study,a total of 95 738 participants (aged 18-98 years old) were included and were categorized into sex-specific quintiles according to serum uric acid concentration which were collected during 2006-2007 by health examinations.The study was followed up for an average of 4 years.We used Cox regression models to calculate hazard ratios (HR) and their 95％ confidence intervals (CI).Results (1) Higher concentrations of serum uric acid were associated with older age,obesity,higher blood pressure,higher serum concentrations of total cholesterol,triglycerides,and high sensitivity C-reactive protein,smoking,alcohol drinking,history of hypertension,hyperlipidemia and atrial fibrillation,and antihypertensive medication use.(2) The incidence of brain infarction for sex-specific quintiles were 0.84％ (33/3913),0.35％ (14/3985),0.44％(17/3888),0.54％ (21/3909),0.91％ (35/3860) in women (x2 =15.676,P =0.003) and 1.18％(180/15 238),1.26％ (191/15 170),1.11％ (170/15 323),1.45％ (221/15 216),1.82％ (277/15 236)in men (x2 =36.641,P =0.000).(3) After adjusting for potential confounders,including age,body mass index,blood pressure,fasting plasma glucose,total cholesterol,triglyceride,smoking,alcohol,and medical history of major chronic conditions and antihypertensive medication use,the HR (95％ CI) of brain infarction across serum uric acid quintiles were 2.06 (1.14-3.72),0.91 (0.45-1.84),1.00 (ref),1.11 (0.58-2.09),1.31(0.73-2.34) in women and 1.07 (0.86-1.34),1.02 (0.47-2.25),1.00 (ref),1.23(1.00-1.52),1.24(1.01-1.52) in men.Conclusions In this prospective cohort study,we find a U-shaped relationship between serum uric acid concentrations and brain infarction,a higher risk of developing brain infarction in association with low or high serum uric acid concentrations.Women with lowest or highest serum uric acid concentrations and men with higher serum uric acid concentrations are more likely to develop brain infarction.This probably because women have lower serum uric acid concentrations relative to men.Confirmation of our findings in larger cohorts with longer follow-up duration is warranted.

Objective To discuss changes of accompanying femoral artery and vein blood gas in patients with burn sep?sis. Methods The retrospective data of twenty-two patients with burn sepsis and forty-three non-sepsis patients (control) was analyzed, and changes of accompanying femoral artery and vein blood gas were compared between two groups. Results Results of femoral artery gas analysis showed that the HCO3-concentration was lower in sepsis group than that of control group. Results of femoral vein blood gas showed that the partial pressure of carbon dioxide [p(CO2)] was higher in sepsis group than that of control group;the oxygen saturation (SvO2) and HCO3-concentration was lower in sepsis group than that of control group (P<0.01). The differences between oxygen partial pressure p(O2), p(CO2), HCO3-concentration, oxygen satura?tion of femoral artery and vein blood gas were significantly higher in sepsis group than those of control group ( P<0.01). Conclusion Results of femoral vein blood gas analysis change obviously in patients with burn sepsis . The detection of accompanying femoral artery and vein blood gas is beneficial to diagnosis of burn sepsis.

Objective To explore the relationship between different blood glucose levels and new carotid artery plaques.Methods A total of 5 440 participants met the inclusion criteria were selected stratified randomly from the 101,510 serving and retired workers of Tangshan Kailuan Company who participated the health examination from 2006 to 2007.The follow-up health examination were respectively preformed from 2010 to 2011 and from 2012 to 2013 which included carotid ultrasound for these 5 440 participants.The 5 440 participants were divided into three groups (ideal blood glucose group,impaired fasting glucose group and diabetic group) according to their fasting glucose levels in 2010-2011 examination.Multivariate Logistic regression analysis was used to analyze the risk factors of new carotid artery plaques.Results Among 5 440 subjects,participants whose FPG,ultrasound data incomplete and ultrasound detection of carotid plaques during the 2010-2011 health examination were excluded,then 3 084 participants were included in this study,among them,175 participants who did not participate the 2012-2013 health examination and 561 participants whose carotid plaque ultrasound data incomplete were excluded.Thus,a total of 2 348 participants were included in the present analysis.The total detection of new carotid artery plaque rate was 15.0％ (352/2 348) after 2 years of follow-up.The detection of new carotid artery plaque rate in normal glucose group(n =1724),impaired fasting glucose group(n=464) and diabetic group(n=160) were 14.2％(245/1 724),14.9％(69/464) and 23.8％(38/160),respectively.The diabetic group was higher than that of the ideal blood glucose group and the impaired fasting glucose group,the difference was statistically significant(P＜0.05).Impaired fasting glucose group and diabetic group had an increased risk of new carotid artery plaque compared with those in ideal glucose group(OR =0.924,95％CI 0.691-1.235 and OR =1.733,95％CI 1.107-2.713,respectively),the difference was statistically significant(P＜0.05).After adjusted for the other risk factors,with the risk-adjusted ratio (OR =1.117,95％CI 0.824-1.513 and OR =1.393,95％CI 0.872-2.226).Conclusion The detection of new carotid artery plaque increase in the diabetic group.However,after adjustment for other risk factors associate with emerging danger of new carotid artery plaque is no significant difference.This requires more long-term follow-up study of a large sample to be further confirmed.

Objective To investigate the correlation of the 24?hour ambulatory systolic blood pressure (SBP) and carotid intima?media thickness(CIMT) in the elderly. Methods A total of 2 464 who were more than or equal to 60 years old participants were selected with random sampling in accordance with the inclusion criteria from the retired workers in Tangshan Kailuan Company. Dynamic blood pressure monitoring, neck vascular ultrasound and other examination were performed for the participants. . Multivariable linear regression analysis was used to analyze correlation between the SBP of 24?hour, daytime and nightime with CIMT, respectively. Results ( 1) The observation population was divided into three groups according to the tertiles of SBP of 24?hour, daytime and nightime, respectively. With the levels of different SBPs inceasing, CIMT values thickened markedly ( P<0. 01 ) . ( 2 ) Multivariable linear regression analysis showed that after adjusting for confounding factors,the SBP of 24?hour,daytime and nightime associated with CIMT positively and linearly(P<0. 05),and regression coefficient(95%CI) were 0. 022(0. 009-0. 035), 0. 021(0. 008-0. 035), 0. 019 ( 0. 006-0. 032) respectively. In addition,clinic SBP step into the multivariable linear regression,and regression coefficient ( 95%CI ) were 0. 016 ( 0. 003-0. 029 ) , 0. 016 ( 0. 003-0. 030 ) , 0. 019 ( 0. 007-0. 032 ) , respectively. Conclusion The effect of increased 24?hour ambulatory SBP on CIMT was greater than the clinic SBP. Active monitoring of 24 h ambulatory blood pressure and maintaining a low level of blood pressure is essential for preventing and delaying atherosclerosis.

Objective To explore the risk factors of cognitive impairment of elderly patients with cerebral infarction in order to provide the theoretical basis for the clinical intervention. Methods A total of 237 cases with senile cerebral infarction were selected as ours subjects who were hospitalized from Mar. 2010 to Jun. 2013 in Kailuan General Hospital Affiliated to Hebei United University. The general condition and medical history were recorded. The auxiliary examination was performed. Cerebral infarction was diagnosed based on the onset to diagnosis standard and MoCA scores of within 2 weeks. The patients with less than 26 MoCA score were diagnosed as cognitive dysfunction and otherwise were thought as normal. Single factor analysis methods and non conditional Logistic regression were applied to analyze the analysis. Results There was no significant difference in terms of incidence between patients with different gender. Patients with age more than 75 years old and lower education levels had the high incidence rate than those with younger age and high education levels( χ2=16. 661,5. 453;P﹤0. 05). The cognitive dysfunction incidence of patients with white collar was lower than those with blue collar(χ2 = 5. 458,P ﹤ 0. 05 ). And the cognitive dysfunction incidence of patients with hypertention,diabetes,heart disease and leukoaraiosis were higher than those without the above diseases(χ2 =28. 423,5. 621,7. 768,6. 070;P﹤0. 05). The incidence of patients smoking more was significantly higher than that of smoking less or no(χ2 =5. 045,P ﹤0. 05 ). Multiple factors and non conditional Logistic regression analysis showed that,67 Senile cerebral infarction patients occurred cognitive impairment within 2 weeks. The independent risk factors for its occurrence included age greater than 75 years( P=0. 000 ),diabetes mellitus( P=0. 043),hypertension(P=0. 000)and leukoaraiosis(P=0. 041). Conclusion There are many risk factors related to cognitive impairment after cerebral infarction occurred in the elderly. The intervention should take in many aspects and the risk factors should early found.

Objective To explore the association between serum uric acid (SUA) and all-cause mortality in men. Methods In this prospective cohort study,data being used was derived from the Kailuan study cohort. A total of 81 110 male workers who had taken part in the Kailuan physical examination were enrolled. Subjects with previous myocardial infarction,stroke,cancer, eGFR<30 ml/(min·1.73 m2)accidental deaths and those ever used drugs that seemed to have showed an effect on blood uric acid,were excluded. All the information was gathered from a unified questionnaire,measured by blood biochemistry and with the mean period of follow up as(47.5±4.3) months. Based on the 2006-2007 SUA value,observed objects were divided into five groups,with multivariate Cox proportional hazard regression analysis used to estimate the relationship between SUA and all-cause mortality in men. Results 1)At the end of the follow-up period in 2010-2011, the number of deaths were 315,278,243,292 and 341 among the different SUA quinte,with incidence rates of all-cause mortality as 2.43%,2.36%,1.96%,2.42%and 2.92%,respectively. 2)Data from the Single factor Cox proportional hazard regression analysis showed that,when comparing with the third quinte,HR values of the all-cause mortality were 1.32(1.11-1.56),1.19(1.00-1.41),1.20(1.01-1.43)and 1.41(1.19-1.66)in other four groups,respectively. 3)When factors were adjusted for age, systolic blood pressure,diastolic blood pressure,body mass index,triglyceride,total cholesterol, high-density lipoprotein cholesterol, low density lipoprotein cholesterol, fasting glucose, high-sensitivity C-reactive protein,smoking history and history of drinking,education,profession, economy,etc.,results from the Multiple Cox proportional hazard regression analysis showed the HR values of the all-cause mortality were 1.26(1.06-1.51),1.20(1.01-1.44),1.25(1.05-1.49),1.42 (1.19-1.68) in other four groups,respectively,comparing to the third quinte. Conclusion Using SUA as the independent risk factor of all-cause mortality,the exceptional levels of SUA were associated with an increasing risk for all-cause mortality while the association of SUA with all-cause mortality appeared an“U”shaped curve.
