Objective To construct the eukaryotic expression vector pEGFP-N1/IL-37b and analyze the expression of IL-37 gene in THP-1 cells. Methods Total RNA was extracted from human peripheral blood mononuclear cells ( PB-MCs) and the coding region of IL-37b gene was amplified by RT-qPCR. Then, the gene was cloned into pEGFP-N1 eu-karyotic expression vector. After transfected the recombinant plasmid into THP-1 cells, the expression of IL-37 was detec-ted by RT-qPCR and Western blot. Results Double restriction enzyme digestion and gene sequencing showed that IL-37b gene was correctly inserted into the eukaryotic expression vector pEGFP-N1. RT-qPCR and Western blot showed that the IL-37 expression level was increased significantly (P<0. 01) after transfection in THP-1 cells. Conclusions We successful-ly constructed a novel anti-inflammatory cytokine IL-37 eukaryotic expression vector pEGFP-N1/IL-37b, which lays a foun-dation for further study on IL-37 functions and its association with related diseases.

Objective To investigate the prevalence of nutritional risk,undemutrition,overweight/obesi-ty,and apphcation of nutrition support in departments of neurology in 3 metropolitan hospitals in Beijing. Methods Adult patients in the departments of neurology from 3 metropolitan hospitals in Beijing were consecutively en-rolled from March 2005 to March 2006.Nutritional Risk Screening 2002(NRS2002)score≥3 was defined a8 nu-tritian risk,while body mass index(BMI)<18.5 ks/m2 as undemutrition.NRS2002 was performed on the next morning of admission and nutritional support evaluation was performed on the 14th day of admission or discharge day.The relationship between nutrition risk and nutrition support was analyzed.Results A total of 753 patients were enrolled.NRS2002 scoring results were obtained in 461 patients.The prevalence of undemutrition was 4.2%and nutritional risk Was 21.2%.Among them 292 cases in undemutrition category were estimated by semm albu-min<30g/L without accurate BML If the cases without accurate BMl were excluded,the prevalence of undemutri-tion was 5.4%and nutritional risk Was 10.8%.Twenty-three patients(14.4%)with NRS2002≥3 received nutrition support.Thirteen patients(2.2%)with NRS2002<3 received nutrition support.The average PN:EN ratio Wag 1:2.Conclusions A large proportion of inpatients were at nutritional risk or undemutrition in the de-partments of neurology in metropolitan hospitals in Beijing.The application of nutrition support Wag somehow inap-propriate in these patients.Evidence-based guidelines are required to improve this situation

OBJECTIVETo evaluate incidence of postoperative delirium after hip surgery in elderly patients by meta-analysis.

METHODSFrom January 1, 2014 to December 31, 2013, clinical literatures about postoperative delirium after hip surgery in elderly patients,were searched from the Pubmed. Literature extract table were formed according to inclusion and exclusion criteria. Stata-12.0 was applied for Meta-analysis. P was used to test heterogeneity of study, random-effect model was performed when I2 > 50%. Subgroup analysis was used according to stage of age, assessment scale of delirium and statistical area of literature. Begg test was used to test publication bias.

RESULTSTwenty-one literatures were included. Incidence of postoperative delirium after hip surgery in elderly patients by weighted and combination was 17% [95% CI (16%, 18%)]. Incidence of postoperative delirium after optional hip surgery was decreased more than emergency operation in included 5 literatures [OR = 0.32, 95% CI (0.22, 0.45)]. Incidence of postoperative delirium in patients less than 80 years old was 21% [95% CI (19%, 23%)], while 21% [95% CI (19%, 24%)] in patients more than 80 years old. Incidence of postoperative delirium in CAM evaluation scale was 23% [95% CI (21%, 26%)], while 19% [95% CI (17%, 21%)] in other evaluation scales. Incidence of postoperative delirium in Asian area was 17% [95% CI (15%, 20%)], while 23% [95% CI (21%, 25%)] in European and American area. There was no publication bias tested by Begg test (P < 0.05).

CONCLUSIONIncidence of postoperative delirium after hip surgery in elderly patients increases higher, especially in emergency operation. A standardizing research method is benefit for evaluate incidence of postoperative delirium after hip surgery in elderly patients, decreasing heterogeneity and publication bias.

Objective To explore different features and influencing factors of 75 g oral glucose tolerance test (OGTT) and glycated hemoglobin Ale (HbAlc) levels in subjects with newly diagnosed diabetes and prediabetes of natural history of type 2 diabetes. Methods All subjects were classified by OGTT into four groups: (1) normal glucose test (NGT), 31 subjects at age of (48. 4±15. 3) yrs (29-75 years old); (2) impaired fasting glucose (IFG), 33 subjects at age of (50. 8±9. 8) yrs (38-72years old) ; (3) impaired glucose tolerance test (IGT), 34 subjects at age of (54. 5±11.4) yrs (33-74years old), (4) T2DM, 117 subjects at age of (54.3 ± 14.1) yrs (29-75 years old). Glucose metabolism was evaluated by results of OGTT and HbAlc levels. The insulin secretion function and insulin resistance (IR) were evaluated by HOMA-β, △I30/△G330, area under curve of insulin (AUCINS)and HOMA-IR respectively. Results (1) Significant changes of HbAlc values among groups were as following order: T2DM(7. 41%)>IGT(5. 85%)>NGT(5.21%) (P<0. 01). HOMA-β value in T2DM, IGT and IFG decreased by 53. 1% (P<0. 01), 29.3% (P<0. 01) and 23.4% (P<0. 05)respectively as compared with NGT group. HOMA-IR value in diabetes group was 1.66-fold of NGT (P<0.01), 1. 29-fold of IFG (P<0.001) and 1.44-fold of IGT (P<0.05). (2) Only 3 h blood glucose concentration (BG) in 75 g OGTT was independently and positively correlated with HbAlc level (r=0. 71, P<0. 01). △I30/△G330 ratio was independently and negatively correlated with both 1 h and 2 h BG of OGTT (P<0.01). AUCins was positively correlated with only 3 h BG of OGTT (P<0.01). HOMA-β was independently and negatively correlated with all OGTT results except 2 h BG(P<0.01). HOMA-IR was an independently and negatively correlative factor of all OGTT results (P<0. 01 or P<0. 05). TG level was independently and positively correlated to only fasting BG (P<0. 05), and waist circumference value had an independent and positive relationship with only 1/2h BG (P<0. 01). Independently correlative factors of OGTT changes included △I30/△G330, AUCINS,HOMA-β, HOMA-IR and circumference values. Only 3 h BG was probably an independent contributor to HbAlc variation. Conclusions There are obvious HbAlc differences among T2DM,IGT and NGT patients. When HbAlc values are over 8%, no significant changes of glucose and insulin levels at 75 g glucose load test are found among subjects.

Glaucoma is a group of diseases which can threaten and damage the optic nerve and its visual pathway, leading to visual impairment as a result. Glaucomatous optic neuropathy is a chronic disease accompanied by apoptosis of retinal ganglion cells ( RGCs ) , visual field defect and cupping of optic nerve head. The gold standard in functional glaucoma evaluation is standard automated perimetry ( SAP) , but it is often limited to the subjective feelings of the patients. Still, visual electrophysiological techniques cannot replace the conventional inspection, but with its rapid development, it has provided a new strategy for the early diagnosis of glaucoma as a supplement because it can show changes in amplitude and latency before visual field defect. Here we review three special electroretinograms and multifocal focal visually evoked potentials in the early diagnosis of glaucoma.

Objective To investigate the effects of δ-opioid receptor agonist DADLE (D-Ala2-D-Leu5-enkephalin) on the hemodynamics and oxygen metabolism in rats with sepsis. Methods Eighty healthy male SD rats were randomly divided into 4 groups ( n = 20 each) : sham operation group (group S), sepsis group (group SEP) ,DADLE, group and DADLE2, group. Sepsis was induced by cecum ligation and puncture (CLP) in SEP, DADLE,and DADLE2 groups. In DADLE1 and DADLE2 groups, 0.5 mg/ml DADLE 10 mg/kg was injected intraperitoneally (IP) 0.5 h before CLP and immediately after CLP respectively. Mean arterial pressure (MAP), left ventricular systolic pressure (LVSP) and ± dp/dtmax were recorded at 0, 2, 4 and 6 h after CLP (T1-4). Blood samples from left common carotid artery and right external jugular vein were collected at T4 for blood gas analysis. The cardiac index (CI), O2 delivery (DO2), O2 consumption (VO2) and O2 extraction rate (ERO2) were calculated.Results Compared with group S, MAP and LVSP were significantly increased at T2, while decreased at T3,4, and ± dp/dtmax was significantly increased in group SEP, MAP was significantly increased at T2, while decreased at T3,4, LVSP was significantly increased at T2,3, while decreased at T4 , and ± dp/dtmax was significantly increased in DADLE, and DADLE2 groups, and CI, DO2 and VO2 were significantly decreased and ERO2 was increased in SEP, DADLE, and DADLE2 groups (P＜0.05). Compared with group SEP, MAP, LVSP and ± dp/dtmax at T3,4 and CI, DO2 and VO2 were significantly increased, while ERO2 was significantly decreased in DADLE1 and DADLE2 groups (P ＜ 0.05). There was no significant difference in the parameters mentioned above between DADLE1 and DADLE2 groups ( P ＞ 0.05). Conclusion δ-opioid receptor agonist DADLE can obviously improve the hemodynamics and oxygen metabolism in septic rats.

Objective To investigate the relationship between serum levels of adiponectin (APN) and retinol binding protein 4 (RBP4) in newly diagnosed type 2 diabetes mellitus (T2DM) patients. Methods 95 newly diagnosed T2DM patients and 55 non-diabetic volunteers from health examination population were studied. The serum concentrations of APN and RBP4 were determined by ELISA. The levels of plasma glucose, lipid profiles and insulin were also measured in fasting samples. Insulin sensitivity was assessed by insulin resistance index (HOMA-IR). The control group and diabetic group were divided into ≥60 years subgroup and <60 years subgroup respectively. According to the guideline designed by Chinese Diabetes Society(CDS)in 2004, the control group and diabetic group were divided into different kinds of abnormal metabolism groups. Results (1)The level of APN was significantly decreased in diabetic group compared with the control group[(7.26±4.69)mg/L vs. (11.93±4.89)mg/L], while the serum level of RBP4 in diabetic group was obviously higher than that in control group[(16.48±7.82) mg/L vs. (10.91±5.26) rag/L]. (2) The prevalence of metabolic syndrome in diabetic group was higher than that in control group (46.3% vs. 7.3%). (3)APN level was decreased with the increasing number of components of MS, and RBP4 level was increased with the increasing number of components of MS. (4) In DM group, APN level was correlated negatively with MS, waist circumference and BMI, and RBP4 level was correlated positively with waist circumference, HOMA-IR, BMI and TG. Conclusions APN and RBP4 levels are significantly associated with metabolic syndrome. Hypoadiponectinemia and higher retinal binding protein 4 may play an important role in the pathogenesis of MS.

Objective To survey the serum level changes of retinal binding protein 4(RBP4)in newly diagnosed type 2 diabetes,and to explore related factors of RBP4 level.Methods According to body mass index(BMI),95 newly diagnosed type 2 diabetes in Beijing Hospital from April to October of 2002 were divided into obese-diabetic group(BMI≥25),normal-weighted diabetic group(BMI

Metastatic epidural compression of the spinal cord is a significant source of morbidity in patients with systemic cancer. With improvment of oncotheray, survival period in the patients is improving and metastatic cord compression is en- countered increasingly often. Surgical management performed for early circumferential decompression for the spinal cord com- pression with spine instability, and spine reconstruction performed. Patients with radiosensitive tumours without spine instabili- ty, radiotherapy is an effective therapy. Spinal stereotactic radiosurgery and minimally invasive techniques, such as vertebro- plasty and kyphoplasty, percutaneous pedicle screw fixation, radiofrequency ablation are promising options for treatment of cer- tain selected patients with spinal metastases.
