Objective To analyze the association between serum uric acid (SUA)level and diabetic peripheral neuropathy(DPN)in the elderly patients with type 2 diabetes mellitus(T2DM).Methods A total of 1 091 cases of elderly T2DM in-and out-patients in our hospital from January 2012 to December 2015 were enrolled in this study.The patients with DPN was diagnosed by neuropathy disability score.All the subjects were divided into two groups according to whether the patients with DPN:NDPN(n=574)and DPN group(n=517).The differences in clinical manifestations and biochemical parameters were compared between the two groups,meanwhile the mobidity rates of hyperuricemia between the two groups were calculated.Logistic regression analysis was used to analyze odds ratios between SUA and the prevalence of DPN.Results The mean serum uric acid of DPN group was(338.79±93.76)μmol/L versus NDPN group's(301.82± 58.94)μmol/L(P＜0.05).The prevalence of hyperuricemia was 20.12％ in DPN group,higher than that in NDPN group(13.24％)(x2 =15.962,P =0.000).Compared with NDPN group,age,duration of diabetes,history of cerebral infarction and the levels of SUA,HbA1C and TG in DPN group were significantly increased,and the levels of eGFR and TBIL decreased(P＜0.05),and there were no significant differences in the other indexes between the two groups (P＞ 0.05).Logistic regression analysis showed that increased SUA level was an independent risk factor for DPN,OR =2.293 (95 ％ CI:1.497-3.824) (P ＜ 0.05).Conclusions It has closely correlation between SUA level and DPN,and SUA is one of the independent impact factors for DPN in the elderly patients with type 2 diabetes mellitus.

The contents of gallic acid, catechin, albiflorin, paeoniflorin, benzoic acid and paeonol extracted in different growth years, collecting season and of different parts of Paeonia lactiflora were determined. The results showed that the contents of catechin and paeoniflorin in Paeonia lactiflora collected in autumn are the highest, and the contents of benzoic acid was lower than that of those collected at other time. The longer is the age of Paeonia lactiflora, the higher is the contents of catechin and paeoniflorin. The contents of catechin and paeoniflorin in the root of Paeonia lactiflora were higher than those in other parts of the plant. There is a certain content of paeoniflorin in the leaves of Paeonia lactiflora. Judging from the result, paeoniflorin is synthesized in the leaf and then transported to the root. Catechin is not synthesized in the leaf, but mainly in the root. Paeonia lactiflora should be collected in autumn, and immature plant should not be collected.

Objective To investigate the risk factors for hip fracture in elderly people in Ningbo,in order to provide the basis for prevention and treatment of hip fracture.Methods A case-control study were conducted in study on 450 cases of hip fracture patients aged over 60 years in Ningbo and 450 subjects of control as 1 ∶ 1 matched case control study.A univariate analysis of hip fracture was performed by x2 test.Risk factors for hip fracture were analyzed by logistic regression.Results Poor self-care ability (OR=5.05),light manual labor occupation (OR=4.10),history of cerebrovascular events (OR=2.59),smoking (OR=2.14) were the risk factors for hip fracture in elderly men,while poor self-care ability (OR=11.36),light manual labor occupation (OR=2.41),osteoporosis (OR=3.19),early menopause (OR=6.89),low body mass index (OR=5.05) were the risk factors for hip fracture in elderly women.The protective factors for hip fracture was milk uptake (OR=0.29) Conclusions Early interventions for hip fracture risk factors,and prevention and treatment of osteoporosis can help reduce the occurrence of hip fracture.

The present study reported the effect of two male antifertility agents gossypol acetic acid and GTW on DNA of C3H10T1/2 mouse fibroblasts. Our results showed that the cells treated with gossypol or GTW at high concentration (2-3 ?g/ml) for 4 hours, show silver grains in their nuclei as much as the positive control group, N-methyl N′-nitro-N-nitrosoguanidine (MNNG) a known carcinogen. However, if the agents were used at moderate concentrations (0.5-1?g/ml), the silver grains were much less, if the concentrations of gossypol or GTW were of 0.1-0.3 ?g/ml, the silver grains were as less as the control group. In a colony-forming test, we found that the cells lost their proliferate ability, since no colonies could be formed, if gossypol or GTW were of high concentration; while at moderate or low concentrations, the colony-forming rate was as high as 8.1-10.5％. Taking all of these results into consideration, we suggest that high concentrations of gossypol or GTW can damage cell DNA severely, moderate concentration of the agents break cell DNA to a certain extent, but the cells can repair, while low concentration of gossypol or GTW exert no obvious effect on cells. The significance of these observations was briefly discussed.

OBJECTIVE To study characteristics and drug resistance of the pathogens of hospital acquired pneumonia(HAP)in cadre ward.METHODS Retrospectively analyzed the commonly encountered pathogens and their antibiotic resistance of HAP in cadre ward from Jan 2005 to Dec 2007.RESULTS A total of 174 strains bacteria were isolated.The top five pathogens were Pseudomonas aeruginosa(17.82%),Klebsiella pneumoniae(14.94%),Staphylococcus aureus(13.22%),Acinetobacter baumannii(9.20%)and Candida albicans(8.62%).Both Gram-negative bacteria and Gram-positive cocci were multiple drug-resistant.CONCLUSIONS The incidence of HAP in cadre ward is high and Gram-negative bacteria are the main pathogens.The strains isolated are multiple drug-resistant.It is important to study the characteristics and drug resistance of the pathogens.

Objective To summarize the operative experience of transumbilical single-port laparoscopic cholecystectomy. Method The clinical data of 15 patients underwent transumbilical singleport laparoscopic cholecystectomy between May to October in 2010 was reviewed. Results The operative time was 30-85(45±16) min,hospitalization time was (2.5 ± 1.1 ) d. No surgical complications such as bile leak or uncontrolled hemorrhage occurred postoperatively. All the incision were healed well and the surgical scar was virtually concealed whithin the umbilicus. Conclusions Transumbilical single-port laparoscopic cholecystectomy is feasible and safe when patients are well selected. Comparing with conventional laparoscopic cholecystectomy, it's more manipulatively difficult.

Renal ischemia reperfusion injury refers to the recovery failure of renal function induced by renal perfusion after ischemia,and resulting in a series of pathophysiological reactions.At present,there are no sovereign drugs for the treatment of renal ischemia reperfusion injury.Based on the pathophysiological characteristics of renal ischemia reperfusion injury and the latest research results at home and abroad,the article reviewed the research progress in the therapeutical drugs for renal ischemia reperfusion injury,including apoptotic protease inhibitors,P-selectin antagonists and antioxidants,which could provide reference for the effective intervention with the disease.

Objective To determine the effect of lean mass and fat mass on bone mineral (BMD) in postmenopausal women of different age groups.Methods A total of 287 postmenopausal women (aged 50 years and over) participated in this study.Individuals were divided into 4 age groups by decades:group 1,50-59 yr (82 cases); group 2,60-69 yr (73 cases); group 3,70-79 yr (66 cases); group 4,80 years and over (66 cases).The BMD of lumbar spine (L2-4),left femoral neck and total hip were measured by dual-energy X-ray absorptiometry.Fat and muscle mass were analyzed by its analysis function and the percent of fat mass and muscle mass were calculated.Then data were processed by the SPSS 18.0 programme.Results One linear regression analysis showed that the L2-4 BMD was significantly associated only with body composition of trunk,while femoral neck (FN) and total hip (TH) BMD were respectively associated with body composition of different parts in group 1.L2-4 BMD was significantly associated only with trunk fat mass and muscle mass (r=0.27,0.25,both P＜ 0.05),but there were no relationships between BMD of FN and TH and body composition of different parts in group 2.The BMD of L2-4,FN and TH were significantly respectively associated with body composition of different parts in group 3 and 4.Conclusions In postmenopausal women,fat mass and muscle mass play an important role in BMD.In postmenopausal women aged 60-69 yr,the body composition has a minimal impact on BMD,and hormone replacement therapy may be the best for osteoporosis prevention and treatment in this period.Different exercise and loosing of weight in postmenopausal women of different ages can prevent osteoporosis and fragility fractures.

Objective To explore the relationship between plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) level and the location and prognosis of acute ST-segment elevation myocardial infarction (STEMI) in elderly people.Methods From May 2012 to April 2014, the 137 elderly patients (aged≥60 years) with acute STEMI within 24 h after symptoms onset admitted in cardiovascular department of Ningbo First Hospital were selected as acute myocardial infarction group (AMI group), and 40 elderly healthy people (age≥60 years) as control group.The plasma NT-proBNP levels were detected by enzyme linked immunosorbent assay(ELISA), and compared between the two groups.The patients in AMI group were classified into four subgroups: anterior AMI group (A group, n=44), anterolateral AMI group (B group, n=21), anterior septal AMI group (C group,n=18) and inferior AMI group (D group, n=54), and the changes of plasma NT-proBNP levels in different infarction location were explored.Meanwhile, all patients were followed up for 30 days and 1 year to observe major adverse cardiac events (MACEs) and mortality rate, then to explore the relationship between plasma NT-proBNP level and prognosis in elderly people with STEMI.Results The plasma NT-proBNP levels were significantly higher in AMI group than in control group [(1 406.2±1 322.5)ng/L vs.(63.7±18.5) ng/L, P＜0.01].The changes of plasma NT-proBNP levels in high-to-low sequence were from A group to B group to C group to D group and to control group (P＜0.05).At 30 days, the plasma NT-proBNP levels were higher in death group than in survival group (P＜0.05), and were higher in MACE group than in non-MACE group (P＜0.05).At one year, there were no significant differences in plasma NT-proBNP levels between death group and survival group (P＞0.05), and the plasma NT-proBNP levels were higher in MACE group than in non-MACE group (P＜0.05).Conclusions In elderly STEMI patients, there is a correlation between plasma NT-proBNP levels and infarct location, with the highest NT-proBNP level in anterior AMI.The plasma NT-proBNP level could predict MACE.
