Objective To explore the dynamic changes of inflammatory cytokines and C-reactive protein(CRP)in patients with acute cerebral hemorrhage and its prognostic value.Methods TNF-α, IL-1β, IL-6, IL-8 and CRP were measured in 120 healthy persons and 120 patients after the onset of acute cerebral hemorrhage at 24 h, 3, 7 and 14 d.Correlation analyzes were performed respectively between bleeding quantity or serious degree in patients with acute cerebral hemorrhage and the above indicators.Receiver operating characteristic curve was emploied to analysis its clinical prediction significance to the deterioration of acute cerebral hemorrhage.Results Different periods of serum TNF-α,IL-1β, IL-6, IL-8, and CRP in patients with acute cerebral hemorrhage were higher than those in healthy controls(P<0.05).There was a positive correlation between brain bleeding quantity or severity and the contents of TNF-α, IL-1β, IL-6, IL-8, and CRP in patients with acute cerebral hemorrhage(P<0.05).The inflammatory cytokines and CRP in the patients had its clinical prediction significance to the deterioration of acute cerebral hemorrhage.Conclusion The serum levels of inflammatory cytokines and CRP is involved in cerebral hemorrhage in the pathophysiological process,and these indicators have important predictive value for patients.

Objective To investigate the serum creatinine (SCr) level in patients with sporadic amyotrophic lateral sclerosis (sALS) and to explore the relationship between the SCr level and the clinical characteristics.Methods A total of 80 patients with sALS,80 patients with multiple system atrophy (MSA) and 80 patients with tension-type headache (TTH) were enrolled in the study.The SCr levels were compared among the three groups.The association between the SCr level and the revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R),the forced vital capacity (FVC) percentage of predicted (FVC％ pred),the site of symptom onset,the duration of disease and the rate of disease progression was evaluated in the sALS group.Results The SCr level was significantly decreased in the sALS group than the other two groups [(60.86 ± 16.80) μmol/L vs (70.05 ± 12.79) μmol/L and (66.97-± 14.14) μmol/L,P ＜ 0.01].In the sALS group,the SCr level was positively correlated with the ALSFRS-R (r =0.315,P =0.005),while no correlation was found between the SCr level and the FVC％ pred,the site of symptom onset,the duration of disease and the rate of disease progression (all P ＞ 0.05).Conclusion The SCr level is an important biochemical index in the patients with sALS and might play an important role in monitoring the disease progression.

Objective To analyze the features of nerve conduction in patients with amyotrophic lateral sclerosis (ALS),and explore the correlation between compound muscle action potential (CMAP)amplitude and disease duration and revised amyotrophic lateral sclerosis functional rating scale (ALSFRSR).Methods Standard motor and sensory nerve conduction studies were performed in 154 patients with ALS.The following parameters were collected including CMAP amplitude,distal motor latency (DML),motor conduction velocity,sensory conduction velocity and sensory nerve action potential amplitude.Regression study was done to explore the correlation between CMAP amplitude and disease duration and ALSFRS-R.Results Motor nerve conduction abnormalities were presented in a majority of the patients with prolonged DML in the tibial nerve,median nerve and ulnar nerve as the most common form (61.06％-81.42％),followed by decreased CMAP amplitude (30.12％-53.98％),decreased MCV (12.05％-16.81％) and absence of CMAP (2.65％-9.73％).Sensory nerve conduction abnormalities were detected in a small proportion of patients and the decreased SCV,decreased SNAP amplitude and absence of SNAP in the sural nerve,median nerve and ulnar nerve were found in 1.22％-2.73％,0-1.82％ and 0-1.22％patients respectively.No correlation was found between CMAP of the common peroneal nerve,tibial nerve,median nerve and ulnar nerve and the disease duration (P ＞ 0.05),while significant positive correlation was established between CMAP amplitude of the median nerve and ulnar nerve and ALSFRS-R (r =0.273,P =0.016;r =0.357,P =0.001).Conclusions Motor nerve conduction is abnormal in a majority of ALS patients with prolonged DML as the most common form,while abnormal sensory nerve conduction is only found in a few of ALS patients.CMAP amplitude of the median nerve and ulnar nerve might be of certain clinical value in evaluating the severity of ALS.

Insulin resistance in insulin sensitive organ results in metabolic disorder such as hyperglycemia, hyperinsulinemia and hyper triglyceridemia which are common features of type 2 diabetes.Insulin resistance in liver cells mainly causes impaired glycogen synthesis, failed to suppress glucose production which is the major contribution to hyperglycemia.FGF-21 as a new metabolic regulator can control fasting blood glucose.The mechanism of FGF-21 effects on regulating plasma glucose has little to known.In order to establish an in vitro insulin resistant model of liver cells and evaluate the effects and mechanism of FGF-21 on glucose metabolism in the cell model, HepG2 cells were incubated with 10-7 mol/L insulin for 24 h to build insulin-resistant cell model.To evaluate the cells for insulin resistance, the cells were stimulated with fresh insulin for 24 h and the glucose uptake by these cells was carried out.The insulin-resistant cells were treated with different concentrations of FGF-21 for 24 h and insulin-treated cells were used as a control.The glucose uptake by the cells was detected by the method of glucose oxidizes/peroxides(GOD-POD);the synergy between insulin and FGF-21 was evaluated.The mRNA expression of GLUT1 in the insulin-resistant cells was detected by the real-time PCR.Glycogen synthesis of the cells was examined by the anthrone method.The results showed that HepG2 cells treated with 10-7 mol/L insulin for 24 h became resistant to insulin and the insulin resistance status was maintained for 48 h without change of cell morphology.FGF-21 could stimulate glucose consumption of the insulin-resistant model in a dose-dependent manner.The glucose consumption and glycogen synthesis of the insulin-resistant model were significantly improved by FGF-21 treatment.FGF-21 showed strong synergy with insulin in glucose uptake and glycogen synthesis of the model cells.While the cells became resistant to insulin, FGF-21 could increase the mRNA expression of GLUT1.Thus, It is concluded that FGF-21 stimulates glucose uptake in insulin resistant HepG2 cells through GLUT1 expression, stimulates glycogen synthesis and improves the glucose metabolism in the insulin resistant liver cell model.

Objective To establish a mouse model of aorta dissection (AD) by β-aminopropionitrile (BAPN) in drinking water + subcutaneously pumped angiotensin II (Ang II) infusion.Methods Forty 3-week-old C57B1/6J male mice were randomly divided into two groups.All animals received 0.1 g/kg/d BAPN in drinking water for 4 weeks.Then the BAPN drinking + saline infusion group and BAPN drinking + Ang II infusion group received continuous saline or Ang II (1,000 ng/kg/min) infusion, respectively, via subcutaneous osmotic minipump for 72 hour.The mice were restricted in a noninvasive computerized tail-cuff system and their arterial systolic blood pressure and heart rate were monitored.Autopsy was performed if a mouse died during the experiment.At the end of the experiment, mice were sacrificed by injection with an overdose of sodium pentobarbital and the aortas were harvested.The formation of aortic false lumen was observed by pathology using hematoxylin-eosin staining.Results The overall incidence of AD in the BAPN drinking administration +Ang II infusion group was 95%, whereas the incidence of AD in the BAPN drinking administration +saline infusion group was only 5%.The mortality from dissecting aneurysm rupture was 24% in the BAPN drinking administration +Ang II infusion group during the experiment.Pathological examination of the aortic cross-sections clearly showed the formation of blood-filled false lumens induced by Ang II.Conclusions A mouse model with high incidence of aortic dissection is successfully established.

Objective: To learn the epidemiological characteristics of fall mortality among the elderly people in Taizhou，and to provide basis for intervention strategies of fall in the elderly. Methods: Data of fall mortality among residents aged 60 years or over in Taizhou from 2016 to 2018，collected from Zhejiang Chronic Disease Surveillance Information Management System，was used for analysis of time，population and geographical characteristics of fall deaths. The epidemic trend of fall mortality in the elderly was described by annual percentage change（APC）. Results: From 2016 to 2018，3 699 cases of fall death in Taizhou were reported，the crude and standardized mortality were 116.90/100 000 and 97.88/100 000. The standardized mortality of fall in women was 106.11/100 000，which was higher than 90.13/100 000 in men（P<0.05）. The standardized mortality of fall in rural residents was 131.20/100 000，which was higher than 28.15/100 000 in urban residents（P<0.05）. The mortality of fall in residents aged 65-69 years from 2016 to 2018 showed an upward trend（APC=4.20%，P<0.05），while the mortality trend of fall in other age groups was not statistically significant（P>0.05）. Conclusion Fall was the first cause of injury death in the elderly aged 60 years or over in Taizhou. Females and rural residents have relatively higher fall mortality.

Objective To learn the effects of family supportive supervisors on medical staff turnover intention. Methods The scales of family supportive supervisor behavior scales, work-family conflict scale and turnover intention scale were used in the study. The data were collected from a questionnaire survey of 214 army tertiary hospitals′ medical staff during October to December 2017. Hierarchical regression analysis was used to establish a model to understand the influence of family supportive supervisor behavior, two-way conflict between work and family, using the independent variables, on turnover intention of medical staff. Results The and family supportive supervisor behaviors had a negative explanation to medical staff turnover intention ( β = - 0. 211, P < 0. 01), work interference with family had a positive explanation to it (β = 0. 358, P < 0. 01), family interference with work had an obscure explanation to medical staff turnover intention (β = 0. 104, P > 0. 05). Work interference with family had a partially mediating effect which influenced family supportive supervisor behaviors on medical staff turnover intention. Conclusions Family supportive supervisor behavior, as an organizational support, can effectively alleviate the work interference on family for medical staff and thus minimize their turnover intention.
