Objective To investigate the clinical features,prognosis and its influencing factors of cerebral venous sinus thrombosis (CVST).Methods The clinical data of 163 patients with CVST were analyzed retrospectively.The outcome was assessed with the modified Rankin Scale (mRS).The influencing factors on prognosis were analyzed by logistic regression model.Results Among the 163 CVST cases,headache was found in 140 cases,motor and (or) sensory deficits in 16 cases,coma in 6 cases,serious intracranial hypertension (＞ 350 mm H2O,1 mm H2O＝0.0098 kPa) in 68 cases,lateral sinus thrombosis in 129 cases,straight sinus thrombosis in 11 cases and intracranial hemorrhage in 21 cases.Follow-up data was obtained by telephone in 150 cases (92％).The mRS scores were 0-1 in 89 cases,2 in 13 cases,3-5 in 44 cases,and 6 in 4 cases respectively.Poor outcome (mRS score ＞ 2) was found in 29.4％(48/163) patients.The total mortality rate was 2.7％ (4/150).Univariate analysis identified factors associated with poor outcome were motor and (or) sensory deficits,straight sinus thrombosis,serious intracranial hypertension (＞ 350 mm H2O) and intracranial hemorrhage.In logistic regression analysis,serious intracranial hypertension(＞ 350 mm H2O; OR =0.169,95％ CI 0.053-0.541,P =0.003) and intracranial hemorrhage (OR =0.075,95％ CI 0.018-0.311,P =0.000) were identified as independent predictors of poor prognosis.Conclusions The clinical manifestations of CVST are complicated and nonspecific.It is still a disease that may lead to death or disability.Serious intracranial hypertension(＞ 350mm H2O) and intracranial hemorrhage were independent predictors of poor prognosis.

In MAST (mRNA accessible site tagging),the DNA tags from synthesized library were employed for identifying mRNA accessible sites. A large number of tags were amplified and subcloned for sequencing to verify mRNA binding profiles. A PCR was designed by using one primer which bridges over the tag terminal sequences. In PCR reaction DNA tag fragments were concatemerized by a bridge primer in reaction cycles. The concatemerized tag fragments were subcloned and sequenced. Dozens of the concatemerized sequences contained thousands tags. The PCR was a simple,effective way which for sequencing tags in a high through put manner.

OBJECTIVETo observe the efficacy and safety of Danlong Oral Liquid (DOL) combined Western medicine (WM) in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset.

METHODSTotally 480 mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset were randomly assigned to two groups in the ratio 3:1, the treatment group (360 cases) and the control group (120 cases). All patients received basic WM treatment. Patients in the treatment group took DOL, 10 mL each time, 3 times per day for 7 days in total, while those in the control group took Kechuanning Oral Liquid (KOL) , 10 mL each time, 3 times per day for 7 days in total. Efficacy for asthma symptoms, lung functions and scores of TCM syndrome and/or main symptoms were evaluated.

RESULTSThe percentage of clinical control and significant effectiveness of asthma symptoms in the treatment group was significantly higher than that of the control group (77.36% vs 56.07%, P < 0.01). The percentage of clinical control and significant effectiveness of lung functions in the treatment group was significantly higher than that of the control group (74.28% vs 50.00%, P < 0.01). The anterior-posterior difference in scores of TCM syndrome was significantly superior in the treatment group than in the control group (-11.26 ± 4.70 vs -9.21 ± 5.09, P < 0.01). The anterior-posterior difference in scores of main symptoms was significantly better in the treatment group than in the control group (-6.58 ± 3.08 vs -5.16 ± 3.45, P < 0.01). The incidence of adverse reactions was significantly lower in the treatment group than in the control group [1.73% (6/346 cases) vs 10.17% (12/118 cases) , P < 0.05].

CONCLUSIONDOL combined WM was superior to KOL in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset.

OBJECTIVETo investigate serum level and gene polymorphisms of matrix metalloproteinase 9 (MMP-9), and platelet glycoprotein VI (GPVI) in patients with acute coronary syndrome (ACS).

METHODSIn a prospective study of 179 patients with documented ACS and 164 controls, we measured baseline serum MMP-9 levels using ELISA and determined the MMP-9/C-1562T and MMP-9/G5564A genotypes using PCR-restriction fragment length polymorphism. Fib serum level was measured by Clauss assay. We also analyzed the Fib/Bbeta-148C/T and GPVI/T13254C polymorphisms.

RESULTSSerum levels of MMP-9 and Fib in ACS patients were significantly higher than in controls (P < 0.001), and serum level of Fib in the acute myocardial infarction group was higher than in patients with unstable angina (P < 0.05). No significant difference between ACS patients and controls was found in frequencies of MMP-9/C-1562T, MMP-9/G5564A, Fib/Bbeta-148C/T, and GPVI/T13254C genotypes and alleles (P > 0.05). The T allele of the Fib/Bbeta-148T polymorphism was associated with increased plasma Fib level (P < 0.05). There was a strong positive correlation between serum level of MMP-9 and Fib (r = 0.289, P < 0.01).

CONCLUSIONSerum levels of MMP-9 and Fib were independent risk factors of ACS. There was an obvious relationship between the Bbeta-148C/T mutation and high Fib level. No significant difference between controls and ACS patients was found in the frequencies of MMP-9 C-1562T and G5564A, Fib Bbeta-148C/T and GPVI T13254C genotypes and alleles (P > 0.05).

OBJECTIVENeonatal sepsis is a common disease and the sepsis-related mortality rate is still high. Until now, there has no ideal diagnostic marker to early identify neonatal sepsis. Expression of neutrophil adhesion molecule CD(11b) was showed as the earlier reaction to the infection/inflammation, and may be applied as an early diagnostic marker for sepsis. This study was to investigate this antigen for early diagnosis of neonatal sepsis related to bacterial infection.

METHODSAccording to clinical symptoms, signs and four indices (WBC, PLT, plasma CRP and ratio of I/T), fifty-one neonates with established or suspected sepsis were allocated retrospectively into two groups of sepsis [n = 23, gestational age of (38.3 +/- 2.4) weeks, postnatal age of (12.7 +/- 8.8) days, body weight: (3.1 +/- 0.8) kg] and suspected sepsis [n = 28, gestational age of (38.8 +/- 1.6) weeks, postnatal age of (11.7 +/- 7.3) days, body weight: (3.3 +/- 0.6) kg]. Fifteen healthy neonates were served as controls [gestational age: (38.5 +/- 1.4) weeks, postnatal age: (8.2 +/- 5.5) days, body weight: (3.3 +/- 0.3) kg]. CD(11b) was quantified with the whole blood flow cytometry and direct immunofluorescence technique.

RESULTSThe expressions of neutrophil CD(11b) in neonates with sepsis and suspected sepsis were (320 +/- 189) MFI and (456 +/- 213) MFI, respectively, which was lower than that of controls [(1,090 +/- 338) MFI, t = -9.01 and -7.56, respectively; P < 0.001]. The expression of CD(11b) was lower in neonates with sepsis than that with suspected sepsis (t = -2.39, P < 0.05). The expression of CD(11b) in neonates with CRP >or= 30 mg/L was (211 +/- 164) MFI, which was lower than those with CRP < 30 mg/L [(505 +/- 265) MFI, t = 2.64, P < 0.05]. The detection of CD(11b) (

CONCLUSIONThe expression of CD(11b) in neonatal sepsis presented with a down-regulation and, the decreased CD(11b) expression might be related to the severity of infections. For the neonatal sepsis the serial measurements of neutrophil CD(11b) expression with the whole blood flow cytometry seemed feasible and reliable in the early diagnosis, evaluation of infection severity and observation of therapy reactions.

Objective: To study the influence of electret on surface charge of fibroblast cells (3T3 cells) and to probe the relationship between cell growth, apoptosis and cell surface charge. Methods: Electrets Teflon PTFE, ±300 V,±1 000 V were used to treat 3T3 cells for 24, 48 and 72 h. Then the influences of electrets on cell cycle and surface charge of 3T3 cells were studied by flow cytometry and electrophoresis, respectively. Results: (1) After 24 h action of negative electrets, electrophoretic mobility (or surface charge) and cell number in S phase of 3T3 cells were significantly increased compared with those in control group. (2) Effect of negative electrets enhancing cell growth and increasing cell surface charge was in proportional to the surface potential of electret. (3) Surface charge density of apoptotic cell was reduced by electret. (4) After 24 h action of positive electret, the cell number in S and G2 phase were decreased and cell surface charge was also reduced. Conclusion: Negative electret can improve cell growth and increase cell surface charge density. Positive electret can restrain cell growth and reduce cell surface charge density. Surface charge of apoptotic cell is less than that of normal cell.
