Objective To investigate the relationship between Serum BNP and heart failure in patients un-dergoing maintenance peritoneal dialysis ( MPD) .Methods 80 uremia patients who underwent MPD and 40 healthy volunteers were enrolled in the study.In the morning of treatment, we assessed their cardiac function according to in-terrogation, physical examination, chest X-ray and echocardiography while detecting BNP, Scr, BUN levels in the fasting venous serum of upper extremity.Results 80 MPD patients were divided into 2 groups:a heart failure group (Group A, n=42) and a normal cardiac function group (Group B, n=38).40 healthy volunteers served as a con-trol group ( Group C ) .There were no significant differences in age, weight and sex ratio among 3 groups ( P>0.05).The time period of maintenance peritoneal dialysis in Group A and B was similar (P>0.05).Compared with Group C, the levels of Serum BNP, Scr and BUN were significantly higher in Group A and B( P<0.05) .There were no significant differences of Scr and BUN between Groups A and B ( P>0.05) .The level of Serum BNP was signifi-cantly higher in Group A than that in Group B (P<0.05).Conclusion The level of Serum BNP may be closely re-lated to the cardiac function and it may be used as a predictor for heart failure in MPD patients.

Objective To study the distribution of the G/A variant at position -30 of the glucokinase gene promoter in southern Chinese subjects with impaired glucose tolerance (IGT) and normal glucose tolerance (NGT) and to investigate the association between different genotypes and indices of glucose metabolism. Methods Four hundred and fourty four unrelated Chinese subjects 〔aged (50.8?12.2)years〕 without diabetics were studied, among them 222 subjects with NGT and 222 with IGT. The G to A substitution at position -30 of the glucokinase promoter, resulting in the loss of a BsiHKA Ⅰ cut site, was detected after BsiHKA Ⅰ digestion of PCR amplified genomic DNA. Results Allele frequency of the A variant was 18.2% in NGT (similar to finding in native Japanese) and 19.8% in IGT subjects. Fasting plasma glucose level was significantly higher in subjects with the A allele (n=153; GA:AA=137:16), when compared to the GG subjects (n=291), 〔(5.35?0.59 vs 5.19?0.53) mmol/L, P=0.006〕. Higherfastingglucoselevelwasalsofound when only IGT subjects with the A variant and GG allele were analyzed 〔(5.54?0.58 vs 5.35?0.52) mmol/L, P=0.02〕. In subjects with NGT, there was no significant difference in fasting plasma glucose levels between different GCK genotypes. Conclusion GCK gene promoter -30 G/A variant is associated with higher fasting plasma glucose levels, and may contributes to the development of IGT in Southern Chinese.

Objective To expolre the clinical characteristic of hospital acquired acute renal failure(HA-ARF).Methods To retrospectively analyse the clinical datas of 103 patients who were suffered from acute renal failure in the duration of hospital stay within 5 years,which was compared with the homeochronous community-acquired acute renal failure(CA-ARF).Results In the 103 cases of HA-ARF,the incidence rate was 32.04% in the major age range from 60 to 74 years old,infection was the most important factor(33.01%),then other factors were cardial and cerebrovascular diseases(17.48%),acute hypovolemia(14.56%) and operation(9.71%);The complicating other organ nonfunction(34.95%),and the mortality rate was 39.80%,all the factors in HA-ARF were higher than that in CA-ARF.Conclusion The main factors of origin in HA-ARF are infection,cardial and cerebrovascular disease,acute hypovolemia and operation.The mortality rate of this disease is higher.Etilogical treatment promptly and dialysis regimen are the main means to rescue these patients.

Objective To explore the relationship between serum uric acid(SUA) levels and metabolic syndrome(MS) in middle-aged and elderly people,and to investigate the impacts of age and gender on the relationship between SUA and MS.Methods A cross-sectional study was carried out in general population aged over 35 years in rural area of Yiling District,Yichang City in 2007.All subjects were investigated by using the standardized questionnaire,physical and biochemical examinations.MS was defined according to the diagnostic criteria of the latest Chinese guidelines.All subjects were divided into different subgroups based on quartiles of SUA levels and age(35-44 years old,45-59 years old,over 60 years old).The relationship of MS with age and SUA levels were investigated.Results 9354 subjects consisted of 3883 males and 5471 females were included in this study.The percentage of subjects aged over 60 years was 21.1％ in men and 17.4％ in women.The prevalence of MS from the first quartile to the fourth quartile were 3.8％,5.5％,7.9％,15.2％ in males,and 3.1％,5.5％,7.9％,16.7％ in females,respectively.The SUA levels was positively correlated with MS in both sexes after adjusting for other confounding factors.By analyzing associated-subgroups based on age and SUA levels,logistic regression analysis showed that the risk of MS was significantly increased with aging and SUA levels in female subjects.The association between age and MS was significantly weaker in men than in women.Conclusions There is a positive correlation between SUA levels and MS.The associations of MS with age and SUA levels are more closely in women than in men.The risk of MS may be highest in middle-aged and elderly women with high level of SUA.

Objective: To explore the correlation between the expression of C-terminal tensin-like protein (CTEN) and the prognosis of hepatocellular carcinoma (HCC). Methods: Using immunohistochemistry, we detected CTEN protein level in samples of primary lesion and adjacent non-tumor lesion collected from 240 patients with HCC. The relationship between CTEN expression and clinicopathology, 5 year recurrent-free survival, or overall survival was evaluated by Chi-square test, Kaplan-Meier, or Cox regression analysis. Results: High CTEN expression was detected in 55% of hepatocellular carcinoma tissues and 20%of adjacent carcinoma tissues (P<0.001). CTEN expression was positively correlated with tumor diameter (P=0.022), venous invasion (P=0.007) or TNM stages (P=0.022). Five-year recurrence-free survival time (P<0.001) and overall survival time (P<0.001) in patients with high CTEN expression were signiifcantly less than those in patients with low CTEN expression. Multivariate Cox regression analysis revealed that the CTEN expression was an independent prognostic marker for HCC (all P<0.05). Conclusion: CTEN protein may play a role in the genesis and development of HCC, and it can function as a prognostic marker.

Objective To investigate the effect of alprostadil in the treatment of interventional angiography in elderly patients with coronary heart disease after contrast nephropathy prevention.Methods From February 1,2014 to January 31,2017,60 elderly patients with coronary heart disease with interventional therapy in Yuncheng Central Hospital of Shanxi Province were divided into two groups,with 30 cases in each group.The control group received hydration therapy,the observation group was given alprostadil combined with hydration therapy.The biochemical index changes before surgery and three days after surgery and incidence of contrast nephropathy were compared between the two groups.Results Before surgery and three days after surgery,the tumor necrosis factor alpha,beta 2 microglobulin, urea and creatinine in the two groups were not changed significantly.Three days after surgery,24h urine protein, superoxide dismutase,glutathione peroxidase,interleukin －6 and C reactive protein levels in the two groups were increased,the increase amplitude of the observation group was smaller.Three days after surgery,the five indicators of the observation group were (185.54 ±86.47)mg,(2.01±1.32)mg/L,(6.18 ±2.13)g/L,(135.56 ±41.58)ng/L, (1.21±1.05 )mg/L,respectively,the differences were ststistically significant between the two groups (t ＝1.21, 1.24,1.50,1.26,1.22;P＝0.03,0.03,0.04,0.03,0.04).Three days after surgery,the creatinine clearance rate of the observation group was (98.67 ±21.56)mL/min,which was higher than that of the control group(t＝2.71,P＝0.01).The incidence rate of contrast induced nephropathy in the observation group (3.33%)was lower than that in the control group(χ2＝5.19,P＝0.02).Conclusion Alprostadil can effectively prevent contrast nephropathy in elderly patients with coronary heart disease after interventional therapy.

Objective To investigate the change of antimicrobial resistance among gram-positive cocci from 1999 to 2006 in Beijing Chaoyang Hospital. Methods Antimicrobial susceptibility test was car-ried out by MIC method, data were analyzed by WHONET 5.3 software. Results A total of 6192 clinical isolates were collected. The top four pathogens were Staphylococcus coagulase-negative, Staphylococcus au-reus, Enterococcus faecalis and Enterococcus faecium. The prevalence of methicillin-resistant S. aureas and coagulase-negative were identified in 88.4% and 86.9%, respectively. The resistance rates of S. aureus to penicillin G and ampicillin were more than 90.0% during 1999-2006. Neither strains of S. aureus nor strains of coagulase-negative Staphylococcus were found resistant to vancomycin. Vancomyein-resistant Enterococci (VRE) strains were firstly isolated in 2003, thirteen vancomycin-resistant E.faecalis isolates were identified as VanB genotype by PCR and sequencing. The VanA gene was confirmed by PCR and sequencing in seven-teen vancomycin-resistant E.faecium, vancomycin-resistance E.faecium rate increased sharply. The most ac-tive antibiotics against E. faecalis were vancomycin, ampicillin, penicillin with the susceptible rates of 98.7%, 95.7% and 85.6%, however, the susceptibility rate of E. faecalis to penicillin decreased from 94.3%-84.6%. The resistance rates of E.faecalis to clindamycin was 99.0%. The resistance rates of E. faecium to erythromycin and clindamycin were more than 95.0%. The resistance rates of E.faecium to ampi-cillin, penicillin, ciprofloxacin were more than 90.0%. The most active antibiotics against E. faecium was vancomycin. The susceptibility rate of E.faecium to tetracycline increased from 27.8% to 82.6%. Conclu-sion Vancomycin remains highly active against gram-positive cocci. A total of 30 Enterococci isolates were found resistant to vancomycin.

Objective:To investigate the correlation between serum ceruloplasmin level and elevated impulsivity in elderly patients with Parkinson′s disease (PD).Methods:227 elderly PD patients treated in Jinhua People′s Hospital from October 2019 to June 2021 were selected as the research objects. They were grouped according to the 75th percentile of serum ceruloplasmin. 0-75th percentile was defined as normal and >75th percentile was defined as high level. The differences of second-order and first-order factor scores of Barratt′s Impulsivity Scale Version 11 (BIS-11) between the two groups were observed. After balancing the general characteristics, the third part of Parkinson′s Disease Rating Scale (MDS-UPDRS), Hoehn&Yahr Scale, Addenbrooke Cognitive Examination Revised Edition (ACE-R), clinical treatment plan and other data, the correlation between ceruloplasmin and BIS-11 was observed.Results:According to the 75th percentile level of ceruloplasmin, 56 patients were included in the high-level group and 171 patients were included in the normal group. The level of ceruloplasmin, the ratio of female patients, MDS-UPDRS Ⅲ, Hoehn&Yahr Scale and ACE-R score in the high-level group were significantly higher than those in the normal group (all P<0.05). The second-order unplanned and corresponding first-order self-control and first-order self-knowledge complexity in the high-level group were higher than those in the normal group (all P<0.05). There was no significant difference in second-order attention, first-order attention, first-order cognitive instability, second-order motivation, first-order motivation, first-order stability and BIS-11 score between the two groups (all P>0.05). After removing the confounding factors by multifactor logistic analysis, ceruloplasmin was correlated with second-order unplanned and its corresponding first-order factors (self-control and self-knowledge complexity) (all P<0.05). Conclusions:The serum ceruloplasmin level in elderly PD patients is related to the elevated level of BIS-11 unplanned impulse.

Objective To investigate and compare the effect of two kinds of transparent dressings in the use of fixed intravenous indwelling needle in restless patients in emergency first aid. Methods A total of 160 restless patients who were required to use intravenous indwelling needle were randomly divided into conventional dressing group and 3M dressing group by random digits table method, 80 patients in each group. The medical transparent dressings(Specification:6 cm × 7 cm) were used for the patients of conventional dressing group, and 3M dressings(Specification:6.5 cm×7.0 cm ) for 3M dressing group. The fixity time, number of cases intravenous indwelling needle detached, replaced time of transparent dressing, number of crimping cases were compared. Results For the conventional dressing group, fixity time was (19.67 ± 7.02) h, replaced time was (18.92 ± 6.58) h, 15 detached cases and 24 crimping cases happened. While for the 3M dressing group, fixity time was (41.64±17.79) h, replaced time was (41.11 ± 17.76) h, 4 detached cases and 7 crimping cases happened. The difference was statistically significant(t=-10.27,χ2=7.23, t=-10.48,χ2=11.56, all P<0.05). Conclusions 3M transparent dressing is suggested in fixing intravenous indwelling needle in restless patient in emergency first aid. It can ensure the use of intravenous indwelling needle during the period, effectively prevents the needle from detaching due to its good fixation effect.
