Objective To investigate the serum C-reactive protein (CRP) level in patients with acute cerebral infarction and acute massive cerebral infarction with multiple organ dysfunction syndrome (MODS),and analyze the clinical value of CRP. Methods The serum CRP level of 50 patients of control group and 50 patients of cerebral infarction admitted to hospital within 7 days (30 patients were admitted into acute cerebral infarction group and 20 patients into acute massive cerebral infarction with MODS group) were determined by immune scatter turbidimetry. Results (1)In cerebral infarction patients,serum CRP level in 48 cases(96%) was equal and over 5 mg/L.In control group,serum CRP level in 3 cases(6%) was equal and over 5 mg/L(P＜0.0 5).(2)The level of serum CRP acute in cerebral infarction group and in acute massive cerebral infarction with MODS group increased significantly than that in control group (P＜0.01).The level of serum CRP in acute massive cerebral infarction with MODS group increased significantly than that in acute cerebral infarction group.(3)When the level of CRP＜25 mg/L,the incidence of MODS in patients with acute cerebral infarction was zero.When the level of CRP≥25 mg/L,the incidence of MODS increased gradually with the rise of CRP. Conclusions There is positive correlation between the serum level of CRP and the severity of acute cerebral infarction and the incidence of MODS.CRP is a useful marker in predicting the prognosis of acute massive cerebral infarction with MODS.

Fibroblast growth factor-21 (FGF-21) is an important metabolism regulator, however, whether FGF-21 has effects on cardiovascular remains unclear. In this study, H2O2-induced injury in H9c2 cells was used as a cell model, the anti-apoptosis potential and mechanism of FGF-21 against oxidative injury were evaluated by MTT assay, flow cytometry assay and real-time PCR. The results showed that FGF-21 could increase the cell survival of H2O2-induced injury in H9c2 cells and prevent H9c2 cells from oxidative stress-induced apoptosis. Furthermore, FGF-21 can elevate SOD activity and regulate Bcl-2/Bax expression in H9c2 cells. The results suggest that FGF-21 have protective effect against the H2O2-induced apoptosis in H9c2 cells.

OBJECTIVETo review the clinical features of the thoracolumbar fracture with ankylosing spondylitis (AS) in order to avoid delayed or missed diagnosis.

METHODSFive patients of thoracolumbar fracture with AS treated from April 2005 to June 2007 in our department were studied retrospectively, male 4 cases, female 1 case, the age from 26- to 72-years-old with an average of 44.8 years. Analysis including: case history, number of the ankylosed vertebras, characteristic of fracture, active state rheumatism.

RESULTSThe patients had the history of AS for average 22.6 years. The mean number of the ankylosed vertebras was 18.2. Of the 5 cases, 1 case encountered traffic accident, 1case was sprained, and 3 cases without trauma were diagnosed as stress fracture. Two cases were trans-vertebra fracture: the fracture line was through T6, T7, or L1 vertebral body respectively; 3 cases were through the disc space: 2 cases were through L1,2 disc space, 1 case was through L2,3. No compression fracture and neurological injury were found. The acute inflammatory index such as ESR and CRP in 4 cases didn't correlate with the degree of pain. The non-steroidal anti-inflammatory drugs (NSAIDs) hadn't significant effectiveness in relieving pain. The patients were diagnosed as 'relapse' of AS in other hospital, and had been misdiagnosed for average 1.51 months.

CONCLUSION1) the fracture is prevalent at the middle or late period of AS when extensive ankylosis has been existed at the thoracolumbar region; 2) the fracture is common at the lower thoracal spine and the upper lumbar spine, and the majority is the stress fracture; 3) the fracture line may be through the vertebral body, but more often through the disc space; 4) it is like an exacerbation of AS and therefore to be missed diagnosis; 5) when the back pain exacerbated suddenly in the middle or late period of AS, the degree of pain not correlating with acute inflammatory index, and the NSAIDs ineffective, the thoracolumbar fracture should be considered.

Objective: To evaluate the impact of coronavirus disease 2019 ( COVID-19 ) prevention and control measures in Huzhou on influenza epidemic strength and characteristics in 2020, so as to provide reference for formulating influenza prevention measures. Methods: Using the influenza surveillance data of the national influenza sentinel surveillance system from January 2015 to July 2020, the seasonal characteristics of influenza epidemic were analyzed, the proportion of influenza-like illness cases ( ILI% ) and the positive rate of influenza virus in January to July of 2020 were compared with those of the same period in 2015-2019, in order to evaluate the impact of COVID-19 prevention and control measures. Results : The ILI% and the positive rate of influenza virus in Huzhou were 3.90% and 15.32% during 2015-2019, while were 4.41% and 12.63% from January to July of 2020. The trends of ILI% during 2015-2019 fluctuated similar, but continued to drop since January 2020. The positive rate of influenza virus peaked from December to March in 2015-2019, also peaked from December 2019 to January 2020, but decreased to 0 in March. ILI% was positively correlated with the positive rate of influenza virus ( r=0.682, P<0.05). The growth rates of ILI% from January to July 2020 were 4.75%, -11.27%, 0.68%, 19.84% and 0.92%, compared with the same period of 2015-2019, respectively. The growth rates of ILI% in January 2020 were much higher ( >57.00% ) and from April to July were much lower ( <-33.00% ) . The growth rates of influenza virus positive rate from January to July 2020 were -47.96%, -36.53%, -3.44%, -35.92% and -39.37%, compared to the same period of 2015-2019, respectively. The growth rates of influenza virus positive rate in January 2020 were much higher ( >11.00% ) and from February to March were much lower ( <-61.00% ). Conclusion Since COVID-19 prevention and control measures were implemented in January 2020 in Huzhou, the ILI% and the positive rate of influenza virus in sentinel hospitals decreased significantly.

OBJECTIVETo investigate the personality traits and intensity dependence of auditory evoked potentials (AEPs) in chronic primary insomnia.

METHODSThirty-seven patients with chronic primary insomnia (insomnia group) and 44 healthy subjects (control group) were enrolled in the study. The AEPs were examined in insomnia and control groups; the personality traits were studied by Zuckerman's Sensation Seeking Scales (SSS) and Zuckerman-Kuhlman's Personality Questionnaire (ZKPQ); and the mood states by Plutchik-van Praag's Depression Inventory (PVP).

RESULTThe scores of neuroticism-anxiety and depression in insomnia group were significantly higher than those in control group (P<0.01); and the scores of impulsivity and aggression-hostility were also higher than those in control group (P<0.05); N1-P2 amplitude of AEP increased with stimulus intensity, which were significantly different in 70, 80, 90,100 dB (P<0.01). There were significant correlations between activity and N1 latency at 80 dB, activity and P2 latency at 100 dB (r=0.270, r=0.276, P<0.05); and between total scores of sensation seeking scale and N1-P2 amplitude (r=0.3746, r=0.35329, P<0.01) at 70 and 90 dB stimulus intensity in insomnia group. There were significant correlations among experience seeking and N1-P2 amplitude, experience seeking and slope rate (P<0.01) at 70, 80, 90, 100 dB stimulus intensity in insomnia group (r=0.539, r=0.3439, r=0.439, r=0.3278). There were significant correlations between sensation seeking of boredom susceptibility and slope rate (r=-0.282998, P<0.05) in insomnia group. There were significant correlations between thrill and adventure seeking and N1-P2 amplitude(r=0.2789, P<0.05) at 90 dB stimulus intensity in insomnia group; there were significant correlations between PVP and N1-P2 amplitude (r=-0.3434, r=-0.3158, P<0.05) at 70 dB and N1 latency at 80 dB in insomnia group.

CONCLUSIONChronic primary insomnia sufferers have higher levels of neuroticism-anxiety, depression, aggression-hostility and impulsivity, and some are correlated with stimulus intensity dependence in AEP.

OBJECTIVETo study the effects of ulinastatin on coagulation in children who underwent open-heart surgery with cardiopulmonary bypass (CPB).

METHODSFifty children who underwent open-heart surgery for ventricular septal defect were randomly divided into two groups: ulinastatin treatment and control. Before CPB, ulinastatin (1.0×10(4) U/kg) was added to CPB priming fluid only in the ulinastatin treatment group. Activated partial thromboplasin time (APTT), prothrombin time (PT), thrombin time (TT), fibrinogen and international normalized ratio (INR) were measured both before and at 1 hr, 6 hrs and 24 hrs after CPB.

RESULTSThe PT in the ulinastatin group was more prolonged than in the control group at 1 hr after CPB (18.7 ± 0.7 s vs 15.5 ± 0.5 s) and 6 hrs after CPB (17.5 ± 0.6 s vs 15.0 ± 0.6 s). The APTT in the ulinatatin group was also significantly more prolonged than in the control group at 6 hrs after CPB (38.7 ± 3.1 s vs 35.3 ± 3.1 s) and 24 hrs after CPB (34.2 ± 3.0 s vs 31.1 ± 2.6 s).

CONCLUSIONSUlinastatin may prolong PT and APTT after CPB, and thus affects coagulation in children.

This study is to evaluate the therapeutic effect of fibroblast growth factor 21 (FGF21) on type 2 diabetic mice model and to provide mechanistic insights into its therapeutic effect. Type 2 diabetic animal model was established with high calorie fat diet and low dose streptozotocin (STZ) injection. Mice were then randomized into 5 groups: model control, FGF21 0.25 and 0.05 μmol x kg(-1) x d(-1) groups, insulin treatment group. Ten age-matched normal KM mouse administered with saline were used as normal controls. Serum glucose, insulin, lipid products and the change of serum and liver tissue inflammation factor levels between five groups of mouse were determined. The results showed that blood glucose, insulin, free fatty acids (FFAs), triglycerides, and inflammatory factor average FGF-21 of type 2 diabetes model group and normal control group were significantly higher (P < 0.01), while compared with insulin group, no difference was significant. Average blood glucose, insulin, blood lipid and inflammatory factor of FGF-21 treatment group compared with type 2 diabetes group was significantly lower (P < 0.01) and insulin group has no difference with the model control group. The results of OGTT and HOMA-IR showed that insulin resistance state was significantly relieved in a dose-dependent manner. Thus, this study demonstrates that FGF-21 significantly remits type 2 diabetic mice model's insulin resistance state and participates in the regulation of inflammatory factor levels and type 2 diabetes metabolic disorders.
