Objective To explore the rate of incidence of cerebral venous sinus thrombosis(CVST)in patients with idiopathic in- tracranial hypertension(IIH).Design Restrospective case series.Participants 92 cases with idiopathic intracranial hypertension.Meth- otis All patients diagnosed with papilledema from January 1,2000 through May 1,2007 at our ophthalmology center.Consecutive pa- tients with a diagnosis of papilledema were identified.Patients with space-occupying lesions,hydrocepbalus,or meningitis were excluded. The remaining patients were evaluated with lumbar puncture,magnetic resonance imaging(MRI)and magnetic resonance venography (MRV).Main Outcome Measures The rate of incidence of cerebral venous sinus thrombosis(CVST)in patients with idiopathic in- tracranial hypertension(IIH).Results Excluding patients with mass lesions,meningitis,or hydrocephalus,the occurrence of CVST was 7 (7.6%)of 92 patients with presumed IIH.One additional patients had a diagnosis of suspected CVST.Cerebral venous sinus thrombosis was diagnosed in 1 of the 7 patients with MRI alone,whereas it was evident in all 7 patients with MRV.Conclusions Cerebral venous si- nus thrombosis accounts for 7.6% of patients with presumed IIH in our ophthalmology services.Magnetic resonance venography in com- bination with MRI is recommended to identify this subgroup of patients.(Ophthalmol CHN,2007,16:410-413)

Objective To analyze the risk factors for postoperative stricture after endoscopic submucosal dissection (ESD) for early stage esophageal cancer.Methods The data of 362 patients with early esophageal cancer treated by ESD from January 2007 to February 2012 were reviewed to investigate the risk factors of postoperative stricture.Results Esophageal stricture after ESD occurred in 42 patients (11.6％)with a mean time from ESD to stricture of (58.5 ± 12.3) days.The rates of mild,median and severe stricture were 16.7％ (7/42),38.1％ (16/42) and 45.2％ (19/42),respectively.Multivariate analysis revealed that lesion range ＞ 3/4 esophageal circumference (odds ration [OR]:44.2 ; 95％ confidence interval [CI]:4.4-443.6) and tumor invasion beyond m2 (OR:14.2; 95 ％ CI:2.7-74.2) were independent risk factors.Stricture level was related to lesion's circumferential extension (relational coefficient (φ) =0.47,P ＜ 0.05) and tumor invasion depth (relational coefficient (φ) =0.647,P ＜ 0.05).Conclusion Circumferential extension and invasion depth of early esophageal cancer were independent risk factors for post-ESD esophageal stricture and related with the degree of stricture.

Objective To investigate the expression and clinical value of miR-127-3p in plasma of patients with breast cancer .Methods 80 cases of breast patients , 70 cases of benign breast tumor patients and 70 cases of normal control group were recruited .A real-time fluorescent quantitative reverse transcription polymerase chain reaction ( RT-PCR ) method for detecting miR-127-3p was established; Liner, reproducibility, and specificity were evaluated.In addition, correlations between the relative expression of plasma miR-127-3p and the concentrations of CEA and CA 153 were assessed.the relationship of miR-127-3p expression and clinicopathological features was further determined by Mann-Whitney test.Results The method for detection of plasma miR-127-3p was established.The relative plasma expression of miR-127-3p in breast patients [ 10.561 ( 5.424 -16.465 ) ] was significantly higher than that in benign breast tumor patients [3.015 (1.987-5.035)] (P=0.000 6) and healthy controls [2.375 (1.173-4.370)] (P=0.000 2).However, there was no significant difference between benign tumor patients and healthy control group (P=0.143).Positive relationship was found between the relative expression of miR-127-3p and the concentration of CA153 (R2 =0.457, P=0.003).The area under the ROC curve (AUC) of miR-127-3pwas 0.763, which was higher than that of CEA and CA 153.No significant difference was found between plasma miR-127-3p expression and clinicalpathological features including tumor size , differentiation and tumor node metastasis stage (P>0.05).Conclusions miR-127-3p was increased in breast cancer patients and may be an important diagnostic index for breast cancer .

Objective To explore the expression and diagnostic value of serum microRNA-574-3p (miR-574-3p) in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC).Methods A total of 90 patients with HBV-related HCC,40 patients with HBV-related liver cirrhosis (LC) and 50 healthy controls were recruited.The expression levels of serum miR-574-3p,α-fetoprotein (AFP) and α-Lfucosidase (AFU) of all subjects were determined.The difference of serum miR-574-3p level between groups was compared.The relation between serum miR-574-3p level of HCC patients and its clinical pathological characteristics was analyzed.The t-test was performed.The relationship between serum miR-574-3p level of HCC patients and AFP,AFU was analyzed by Spearman correlation analysis.The diagnostic efficacy of them as diagnostic markers was evaluated by receiver operating characteristic curves (ROC) and the area under the curve (AUC)(95％ CI (confidence interval)).Results The relative quantity expression of serum miR-574-3p of HCC group,LC group and healthy group was 2.152(1.654,3.061),1.292 (0.984,1.666) and 1.018 (0.750,1.726),respectively.The expression level of serum miR-574-3p of HCC group was significantly higher than those of LC group and healthy control group,and the differences were statistically significant (t=2.726 and 2.845,both P＜0.01).The expression level of serum miR-574-3p of HCC patients was significantly different in tumors with different degree of differentiation (t=2.262,P=0.039),different stage (t=2.354,P=0.025) and different HBV DNA concentrations (t=2.771,P＜0.01).There was no correlation between serum miR-574-3p level and AFP (r2 =0.076,P=0.505),AFU (r2 =0.082,P=0.422) in HCC patients.When compared HCC group with LC group,AUC of serum miR-574-3p of was 0.823 and 95％ CI was 0.750 to 0.897.When compared HCC group with healthy control group,AUC of serum miR-574-3p was 0.840 and 95％CI was 0.769 to 0.910.Conclusions The expression level of serum miR-574-3p of HCC patients is significantly higher than those of LC patients and healthy controls.Serum miR-574-3p may be an important biomarker in the diagnosis of HCC.

Coronary artery disease (CAD) is one of the leading causes of death. Safflower attracts great attention owing to its anti-ischemia/reperfusion injury effect. Ninety-three patients with CAD were included and randomized into safflower treatment group, PCI group and control group. Low-dose dobutamine stress echocardiography (DSE) was performed to measure end-systolic volume (ESV), end-diastolic volume (EDV), left ventricular ejection fraction (LVEF) and wall motion score index (WMSI) to determine the recovery of hibernating myocardium and cardiac function in all patients before treatment and after 3-month follow-up. The study was to investigate the effects of safflower on hibernating myocardial revascularization and cardiac function. It was found that LVEF was significantly improved, while the ESV and WMSI were significantly reduced after 2-week treatment in safflower and PCI treatment groups. No significant differences were found between safflower and PCI treatment groups in ESV, EDV, WMSI and LVEF after treatment Safflower injection effectively improved hibernating myocardial function.

OBJECTIVETo study the concentrations of IL-4 and IL-13 in bronchoalveolar lavage fluid (BALF) in neonates with respiratory distress syndrome (RDS) and concurrent ventilator-associated pneumonia (VAP).

METHODSSixty-eight neonates with RDS undergoing mechanical ventilation for over 48 hrs were enrolled. IL-4 and IL-13 levels in BALF were measured using ELISA 1, 72 and 96 hrs after mechanical ventilation. The results were compared between the neonates with concurrent VAP (n=37) and without (n=31).

RESULTSThe levels of BALF IL-4 96 hrs after ventilation in the VAP group (35.34+/-1.78 ng/mL) were significantly higher than those in the non-VAP group (13.69+/-2.47 ng/mL, P<0.05). The levels of BALF IL-13 96 hrs after ventilation in the VAP group (33.74+/-2.74 ng/mL) also increased significantly compared with those in the non-VAP group (13.50+/-3.81 ng/mL) (P<0.05). There were significant differences in BALF IL-4 and IL-13 levels between 1 hr and 96 hrs in the VAP group (P<0.05).

CONCLUSIONSBALF IL-4 and IL-13 levels increase in neonates with RDS and concurrent VAP. IL-4 and IL-13 may involve in the regulation of the inflammatory immune response.

OBJECTIVETobacco smoking results in increased platelet aggregability, which suggests that low-dose aspirin used in common clinical practice may not effectively inhibit platelet activity in smokers with coronary heart disease (CHD). This review was performed to assess the effect of aspirin on platelet aggregation in patients with CHD.

DATA SOURCESWe performed an electronic literature search of MEDLINE (starting from the beginning to March 15, 2009) using the term "smoking" or "tobacco" paired with the following: "platelet", "aspirin" or "coronary heart disease".

STUDY SELECTIONWe looked for review articles regarding the effect of tobacco smoking on platelet activity and on the anti-platelet efficacy of aspirin in healthy people and patients with CHD. The search was limited in "core clinical journal". In total, 1321 relevant articles were retrieved, and 36 articles were ultimately cited.

RESULTSTobacco smoking results in increased platelet aggregability, which can be inhibited by low-dose aspirin in the healthy population. However, in patients with CHD, the increased platelet aggregability can not be effectively inhibited by the same low-dose of aspirin. A recent study indicated that clopidogrel or an increased dose of aspirin can effectively inhibit the increased platelet aggregability induced by tobacco smoking in patients with CHD.

CONCLUSIONSIt is important for patients with CHD to quit smoking. For the current smoker, it may be necessary to take larger doses of aspirin than normal or take an adenosine diphosphate receptor inhibitor along with aspirin to effectively inhibit the increased platelet activity.

OBJECTIVETo compare results of the growth and development of the upper dental arch and the velopharyngeal closure of the cleft patients treated by two methods.

METHODSThe dental cast of patient and X-ray films were measured and the statistical medical records were analyzed.

RESULTSThe transverse distance of upper dental arch was found to be wider in group A than in group B. The anterior-posterior distance of the dental arch in bilateral cleft group was shorter in group A than in group B. The difference of the two groups were gradually lessened as age increases. Bony bridge in alveolar gap was 63% and 83.3% in unilateral and bilateral cleft group respectively. 15% of cases in group A and 35.2% in group B needed pharyngeal flap.

CONCLUSIONSThe stable upper dental arch in group A can opposes the pressure from the lip muscles, this maintains the width of the arch. But A-P distance of upper dental arch in BCLP in group A should be followed up after the age of 9 years. Pharyngeal flap is needed less in group A than in group B.
