ObjectiveTo investigate the effects of astragalin on pulmonary edema after acute cervical spinal cord injury in rats.MethodsA total of 200 adult Wistar rats weighing 240-250 g were randomly divided into five groups:astragalin group,low concentration astragalin group,physiological saline group,blank group and sham group,with 40 rats in each group.The rats with cervical spinal cord injury were induced at C7 by modified Allen' s method,with the dropping weight of 10 × 2.5 g · cm.In the sham group,the laminas were removed only,leaving spinal cord at the C7 intact.Each group was further divided into four time points:24 hours,3 days,1 week and 2 weeks after the modeling,with 10 rats in each time point,according to the specimen collection time.Rats were sacrificed at different time points to observe the pathological change of the lung tissue using optical microscope,measure the lung wet/dry weight ratio (W/D) and protein concentrations of the serum and bronchoalveolar lavage fluid and calculate the lung W/D and lung permeability index (LPI).ResultsAt the same instant,the W/D and LPI in the astragalin group and low concentration astragalin group were lower than those in physiological saline group and blank group,with the lowest value in the astragalin group at day 3 after injury ( P ＜0.05 ).ConclusionsRats with acute cervical spinal cord injury may cause pulmonary edema,which can be efficiently alleviated through early use of astragalin.

Objective To investigate the expression of lung keratinocyte growth factor receptor (KGFR) in rats with acute spinal cord injury (ASCI) in different time points and its role in lung edema.Methods Thirty-two adult Wistar rats weighing 240 g to 260 g were assigned to experimental group (n =16) and control group (n =16) according to the random number table.Each group consisted of time points of 24 hours,3 days,1 week and 2 weeks after the modeling (4 rats per time point).A rat model of ASCI in experimental group was induced at C7 segment by dropping a weight of 10 g from the height of 2.5 cm (Allen' s method).In control group,laminas were removed only,leaving spinal cord at C7 intact.Rats were sacrificed at each time point for measurement of lung wet/dry weight ratio,Western blot analysis of expression of lung KGFR protein and RT-qPCR detection of lung KGFR mRNA expression.Results After ASCI in rats,the expressions of lung KGFR protein and mRNA began to drop at 24 hours (0.23 ±0.06,0,012 1 ±0.002 3),reached the trough at 3 days (0.17 ±0.04,0.008 5 ±0.001 7)and picked up at 1 week.Expression of lung KGFR mRNA in experiment group showed statistically significant difference from that in control group at 24 hours and 3 days (P ＜ 0.05),whereas in each time point the difference of KGFR protein expression between experiment and control groups was statistically significant(P ＜0.05).Variation trend of KGFR expression was in parallel with the severity degree of pulmonary edema.Conclusion Lung KGFR presents significant down-regulation in ASCI rats and this may be associated with the development of pulmonary edema after ASCI.

Objective To investigate the effect of combination of cervical manipulation with cervical conditioning exercise for the treatment of cervical spondylosis of neck type or nerve root type. Methods Seventy-two patients were randomly divided into a treatment group (37 patients) or a control group (35 patients) by using a random number table. Patients in the treatment group and in the control group were treated with combination of cervical manipulation or cervical manipulation only, respectively. At the end of treatment and 3 months, treatment effects were assessed by Neck Disability Index (NDI) and Visual Analog Scale (VAS). Results NDI scores in both of the treatment group and the control group after treatment were significantly lower han those before treatment (t=4.471 in the treatment group, t=3.599 in the control group, all P<0.05), and NDI score in the treatment group were significantly lower than that in the control group after treatment (t=-2.085,P<0.05). Follow-up at 3 months, NDI score in the treatment group was significantly lower than that in the control group (t=-4.549, P<0.05). Proportions of improved patients, as assessed by NDI items, including pain intensity, personal care, lifting, reading, headaches, concentration, work, sleeping, driving and recreation in the treatment group were significantly higher than those in the control groups (Z=-3.521,-3.331,-3.003,-3.001,-3.265,-3.198,-3.016,-3.000,-2.102,-2.971, respectively, all P<0.05). VAS scores in both of the treatment group and the control group after treatment were significantly lower than those before treatment (t=7.986 in the treatment group, t=6.507 in the control group, all P<0.05), and VAS score in the treatment group were significantly lower than that in the control group after treatment (t=-2.426,P<0.05). Follow-up at 3 months, the VAS score in the treatment group was significantly lower than that in the control group (t=-7.065, P<0.05). Proportions of improved patients in the treatment group was significantly higher than that in the control group (91.89% vs 74.29%; χ2=4.014, P=0.045). Conclusion Combination of cervical manipulation with cervical conditioning exercise may be superior to cervical manipulation only for the treatment of cervical spondylosis of neck type or nerve root type.

The effects and toxicities of the second-line treatment were assessed. The progression-free survival time(PFS) and overall survival time(OS) were analyzed. Results The disease control rate was 66.7 %, with a progression-free survival time of 6 months, and a overall survival time of 17.3 months. The 1-year survival rate was 63.3 %. The toxic effects were as expected. Conclusion The doeetaxel-based agent is active in patients with paelitaxel-resistant advanced NSCLC.

Objective To investigate the factors which may affect the secretions of human leptin and free fatty acids (FFA) by measuring plasma glucose, serum insulin, leptin and FFA levels during reduced sample number intravenous glucose tolerance tests (IVGTT) in the subjects with different status of insulin resistance and ? cell function. Methods According to oral glucose tolerance test, 7 normal, 10 overweight/obese individuals, 12 subjects with impaired glucose tolerance (IGT) and 11 with type 2 diabetes mellitus (DM) were recruited. During IVGTT, serum insulin, leptin and FFA levels at 12 time points were simultaneously measured. Results Compared to the stable secretion of leptin, during 180 min in the IVGTT, the FFA secretion showed a "U" shape profile. The correlation analysis showed that the average serum leptin and FFA levels in 3 h were independent to fasting plasma glucose concentration. The partial correlation coefficient of leptin and insulin decreased after being adjusted for FFA (before r=0.77, P0.05). Conclusion The changes of serum FFA levels in IVGTT are more significant than those of leptin after glucose loading. Fasting plasma glucose levels do not significantly affect the average serum levels of leptin and FFA. On the contrary, insulin manifests such action but does not affect the secretion profile of these parameters.

Objective · To explore the relationship between baseline lipid profiles and long-term cardiovascular outcomes after intervention with hypoglycemic drugs metformin and glipizide and to detect lipid components that can predict the long-term cardiovascular effect of metformin and glipizide.Methods· Liquid chromatography-quadrupole time of flight-mass spectrometry (LC-QTOF/MS) was used to measure 119 lipid components in baseline serum for 116 patients with type 2 diabetes (T2DM) and atherosclerotic heart disease (CHD) who were treated with glipizide (56 cases,the glipizide group)or metformin (60 cases,the metformin group).Cardiovascular complex end points (including cardiovascular death,all-cause death,nonfatal myocardial infarction,nonfatal stroke,and arterial revascularization) of all patients were followed up.The relationship between lipid components and cardiovascular complex end points was analyzed with Logistic regression analysis.The category-free net reclassification index (cfNRI) and the integrated discrimination improvement (IDI) were used to evaluate whether lipid components are helpful for predicting the recurrent cardiovascular events.Results· The differences in baseline drug distribution,clinical characteristics,and biochemical indexes between two groups were not statistically significant,except for diuretics use,serum PC (O-34:2) level,and SM (d18:0-24:0) level.Logistic regression analysis showed that baseline ChE (20:4) was a protective factor for recurrent cardiovascular events in the glipizide group (OR=0.87,P=0.039).ChE (20:4) significantly increased the cfNRI and IDI of cardiovascular complex end points by 69％ and 0.07,respectively (P=0.011,P=0.028).Baseline SM (dl 8:1-22:0) was a risk factor for recurrent cardiovascular events in the metformin group and all participants (OR=1.65,P=0.039;OR=1.64,P=0.014).SM (d18:1-22:0) significantly increased the cfNRI of cardiovascular complex end points in the metformin group and all participants by 74％ and 55％,respectively (P=0.012,P=0.005).Conclusion· Of 119 lipid components measured with LC-QTOF/MS,baseline ChE (20:4) is a protective factor and SM (d18:1-22:0) is a risk factor for cardiovascular complex end points in with T2DM and CHD patients after long-term treatment with metformin and glipizide.Both lipid components are helpful for improving the prediction of recurrent cardiovascular events.

ObjectiveTo compare the sensitivity and specificity of a new index of insulin resistance (IR) derived from plasma triglyceride and glucose with homeostasis model assessment for insulin resistance index ( HOMA-IR) and insulin sensitivity index from frequent sampling intravenous glucose tolerance test (FSIGT-ISI).Methods A total of 1024 subjects (240 normal control,335 with obesity,312 impaired glucose regulation,and 137 type 2 diabetes mellitus) were included in the present study.Standard oral glucose tolerance test,insulin release test,lipid profiles,and other biochemical markers were measured. Among them 540 subjects were selected to undertake FSIGT.TyG index is derived from plasma triglyceride and fasting glucose.TyG2 index is derived from plasma triglyceride and postprandial 2 plasma glucose.ResultsPearson correlation coefficient between TyG and HOMA-IR or FSIGT-ISI was 0.427 ( P＜0.01 ) and -0.100 ( P=0.024 ),respectively,and that between TyG2 and HOMA-IR or FSIGT-ISI was 0.455 ( P＜0.01 ) and - 0.162 ( P＜0.01 ),respectively.The sensitivity and specificity of TyG index for diagnosis of IR was 68.5％ and 63.5％ compared with HOMA-IR,and 68.5％ and49.5％ compared with FSIGT-ISI.For TyG2 index,the slightly higher sensitivity ( 81.7％ with HOMA-IR,75.7％ with FSIGT-ISI),but lower specificity (51.5％ with HOMA-IR,48.2％ with FSIGT-ISI) were found.ConclusionsBothTyGandTyG2 indices could be used as a surrogate for assessing IR in Chinese subjects.However,considering its moderately high sensitivity but low specificity,these two indices are limited in the use of large-scale epidemiological screening.
