Objective To observe the effect of carvedilol and metoprolol in patients with chronic heart failure (CHF) and its effect on TNF-α and IL-6.Methods 94 cases of CHF were randomly classified into carvedilol group with 47 cases and metoprolol group with 47 cases, which were treated with metoprolol and metoprolol,respeetively.The clinical effects and the lovels of TNF-α and IL-6 were compared.Results The clinical effeetive rate in carvedilol group was significantly higher than that in metoprolol group( P < 0.05 ).After treatment, the levels of TNF-α and IL-6 were significantly decreased in both groups (P < 0.05 ).Moreover, the levels of TNF-α and IL-6 in carvedilol group were significantly lower than those in metoprolol group after treatment (P < 0.05).Conclusion Carvedilol in improving clinical effective rate and decreasing the levels of TNF-α and IL-6 was better than metoprolol,whieh played an important role in treatment of CHF.

Accurate knowledge,diagnosis and treatment of breast ductal carcinoma in situ(DCIS),are crucial in controlling the development of breast cancer.In the diagnosis phase,breast ultrasound is commonly used as a screening tool,and a clear diagnosis can be made by mammography.Meanwhile,serological tests contribute to the detection of DCIS in early stages.In the treatment,the optimal surgical operation method remains debatable.It is widely acknowledged that the radiotherapy of postoperative patients should become more individualized.In addition,corresponding endocrine therapy helps those ER positive patients to reduce the recurrence.In the development of DCIS to invasive cancer,there are changes in gene and protein expressions,which may be a potential direction for further research.

The authors described two cases with primitive trigeminal artery. Case 1 was a 32-year-old woman who suffered dizziness and a serious pulsatile intracranial bruit on the left ear, and sometimes associated with pulsatile intracranial bearing-pain on the left temporal side six months before she was admitted to the hospital. She also suffered from obvious diplopia on left lateral gaze for the last 5 months. She had suffered no recent trauma. Magnetic resonance imaging(MRI) demonstrated a suspected intracranial aneurysm located in left cavernous sinus. Digital subtraction angiography (DSA) was performed and a primitive trigeminal artery-cavernous sinus fistula in left side was found. Intraluminal occlusion of the fistula was successfully performed immediately after angiography using 6 Guglielmi detachable coils (GDC), and the patient was cured finally. Case 2 was a 28-year-old woman who suffered a serious intermittent cephalodynia associated with soreness on the left body two years before she was admitted to the hospital. She had suffered no recent trauma. Magnetic resonance angiography(MRA) demonstrated a suspected intracavernous aneurysm of the right internal carotid artery, Digital subtraction angiography (DSA) was performed. Right internal carotid angiography showed a primitive trigeminal artery (PTA) run between the cavernous segment of the internal carotid artery and the distal portion of the basilar artery. On initiation of PTA of R-ICA a small wide-necked saccular aneurysm was incidentally visualized. The aneurysm was successfully embolized after angiography using 2 Stent (Neuroform, 4.5mmm × 20mmm)-assisted detachable coils (Matrix), the ICA and PTA were preserved, and the patient was cured finally.

Objective To investigate the association between RNF213 rs6565666 polymorphisms and intracranial cystic aneurysms in patients from Guangdong province. Methods Two hundred and fifty patients with intracranial cystic aneurysms, admitted to and conformed by digital substraction angiography (DSA) in our hospital from February 2016 to October 2018, were selected as experimental group; and 250 patients without intracranial aneurysms conformed by DSA, CT angiography or magnetic resonance angiography at the same time period were used as control group. The genotypes of rs6565666 locus of RNF213 gene were detected by polymerase chain reaction-ligase detection reaction (PCR-LDR). Results As compared with those in the control group, percentages of AG and AA genotypes were significantly higher and percentage of GG genotype was statistically higher at rs6565666 locus of patients from the experimental group (P<0.05). The proportion of allele A at rs6565666 locus in the experimental group was statistically higher as compared with that in the control group (P<0.05). In the experimental group, 112 patients had ruptured aneurysms and 138 patients did not have ruptured aneurysms; there was no statistically significant difference in the genotype distribution of rs6565666 between the ruptured group and the non-ruptured group (P>0.05). Conclusion RNF213 gene rs6565666 polymorphism is associated with intracranial cystic aneurysms in patients from Guangdong province.

Objective To evaluate the effect of cerebral microbleeds (CMBs) on intracranial aneurysm rupture and hemorrhage. Methods A total of 2023 patients with intracranial single aneurysms (944 un-ruptured aneurysms and 1029 ruptured aneurysms) were enrolled in our study. The 3D-DSA was applied to all patients to evaluate the aneurysm sizes, locations, and morphous features, and to confirm the presence of A1 dominance and variations of Circle of Willis; moreover, aspect ratio (AR), size ratio (SR) and aneurismal inclination angle were measured. The presence of CMBs identified by T2-weighted gradient-recalled-echo sequence on magnetic resonance imaging (MRI) was evaluated; the clinical data of combined with/without CMBs patients were compared. Ninety-two untreated intracranial aneurysms patients combined with CMBs were followed up to evaluate the incubation periods of CMBs-related intracranial aneurysm rupture and hemorrhage; the clinical data of patients with un-ruptured aneurysms and ruptured aneurysms were compared; the risk factors of intracranial aneurysm rupture and hemorrhage were analyzed by univariate and multivariate Logistic regression analyses. Results CMBs confirmed by MR imaging were presented in 158 patients, with 7.81％ incidence rate (158/2023). Age, proportion of smokers, aneurysm inclination Angle, SR, narrow neck, irregular aneurysm shape, proportion of rupture and hemorrhage, aneurysm sites, and hypertension showed significant differences between patients without CMBs and patients with CMBs (P<0.05). In the untreated intracranial aneurysms patients combined with CMBs, 27 had intracranial aneurysm rupture and 65 did not appear intracranial aneurysm rupture; the rupture time was 3-46 months, with an average of (15.07± 10.76) months. As compared with the un-ruptured group, the ruptured group had a statistically higher proportion of patients with irregular aneurysm morphology (P<0.05). Univariate analysis showed that CMBs, female, age, aneurysm size, aneurysm morphology, ICA and ACA aneurysms, AR, variations of Circle of Willis, hypertension grading II and III, diabetes mellitus with fasting blood glucose≤6.0 mmol/L, hyperlipidemia, coronary heart disease, and drinking alcohol were important factors affecting intracranial aneurysm rupture, and the differences were statistically significant (P<0.05). Multivariate Logistic regression analysis showed that CMB was an independent risk factor for intracranial aneurysm rupture and hemorrhage; as compared with patients without CMBs, patients with CMBs had a 1.75 fold increased risk of aneurysm rupture. Conclusions Patients with intracranial aneurysms with older age, smaller aneurysm inclination Angle and larger SR are more likely to be associated with CMBs. Intracranial aneurysms with CMBs patients with irregular morphology are prone to have rupture and hemorrhage. CMBs is an independent risk factor for intracranial aneurysm rupture and hemorrhage.

Objective To investigate the role of hesperitin in regulating inflammatory response in early brain injury after subarachnoid hemorrhage (SAH). Methods A total of 96 adult male SD rats were divided into sham-operated group, SAH group, solvent group and intervention group (n=24) by random number table method. The SAH rat models in the latter three groups were prepared by carotid artery puncture method; the rats in the intervention group were given oral administration of hesperidin solution, which was dissolved in 5％ dimethyl sulfolide (DMSO), with a concentration of 1 mg/100 μL and a dosage of 40 mg/kg within 30 min after operation; rats in the solvent group were given oral administration of an equal volume of 5％ DMSO solution. Modified Garcia behavioral scale was used to evaluate the neurobehavior of rats, and the wet/dry weight method was used to measure the water content in the brain tissues of the left and right hemispheres of the rats 24 h after SAH. Immunofluorescence staining was used to detect the microglia activation, Fluoro-dyed Jade C staining was used to assess the brain neuron degeneration, enzyme-linked immunosorbent assay (ELISA) was employed to detect the inflammatory factors interleukin (IL)-1β, IL-6 and tumor necrosis factor-α (TNF-α) content in the brain tissues, and Western blotting was used to detect the nuclear factor-κB (NF-κB) and phosphorylated (p) -NF-κB protein expressions. Results As compared with the solvent group, intervention group had significantly increased improved modified Garcia behavioral scale scores (10.08±1.73 vs. 13.83±1.70), and significantly decreased water content of brain tissues in the left and right hemispheres ([81.44 ± 1.05]％ vs. ([79.14±0.82]％; [80.55±1.55]％ vs. [78.79±1.02]％), significantly smaller number of CD68+ and Iba1+ microglias (30.17±1.04 vs. 10.67±0.75; 29.33±1.16 vs. 12.00±0.41), significantly smaller number of degenerate neurons (53.21±0.94 vs. 31.33±0.28), significantly reduced levels of inflammatory cytokines IL-1β, IL-6 and TNF-α ([429.88±106.32] pg/mL vs. [221.50±48.80] pg/mL; [1015.50±221.80] pg/mL vs. [448.11±93.40] pg/mL; [1021.75±149.17] pg/mL vs. [595.71±190.81] pg/mL), and significantly lower p-NF-κB/NF-κB ratio (1.13±0.07 vs. 0.71±0.02, P<0.05). Conclusion Hesperitin may reduce the inflammatory response mediated by microglia after subarachnoid hemorrhage by inhibiting NF-κB pathway, thereby improving the neurological dysfunction of rats.

Objective To investigate the impact of lack of progesterone receptor ( PR) expression on the prognosis of patients with operable ER ( estrogen receptor)?positive invasive breast cancer. Methods We retrospectively analyzed the clinicopathological features, treatment and survival data of 318 women with ER+/PR+ and ER+/PR? invasive breast cancer. Results Among the 318 patients, there were 219 PR?positive and 99 PR?negative cases. The 5?year overall survival ( OS ) rate was 92. 5%, and the 5?year disease?free survival ( DFS) rate was 87. 2% in the 318 ER?positive patients. Among them, the 5?year OS rates were significantly different between the PR?positive group (94.6%) and PR?negative group (87.8%, P=0.020), and the 5?year DFS rates were also significantly different from each other (89.8% and 81.6%, respectively, P=0.019).Univariate analysis showed that PR status, tumor size, T stage, axillary lymph node metastasis, and clinical stage were prognostic factors for OS ( P<0.05 for all) . Multivariate analysis showed that lack of PR expression, T stage ≥2, and positive axillary lymph node metastasis were independent risk factors for poor DFS and OS in ER?positive breast cancer patients ( P<0. 05 for all ) . Subgroup analysis showed that lack of PR expression was not significant in predicting poor DFS or OS when patients were in stageⅠ or with a small tumor (≤2 cm) (P>0.05 for all), and also showed that premenopausal women with PR?negative disease had poorer DFS and OS than PR?positive patients ( P<0.05 for both) . Conclusions Lack of PR expression is an independent risk factor for poor prognosis in patients with operable ER?positive invasive breast cancer, especially in patients with a large tumor (>2 cm) , advanced clinical stage ( StageⅡ or Ⅲ) or in premenopausal status.

Objective To explore the relations of morphologies of intracranial tiny aneurysms with gender,age,hypertension and aneurysm lesions of the patients.Methods A retrospective analysis of clinical data of 112 patients with intracranial tiny aneurysms,admitted to our hospital from January 2009 to December 2012,was performed; according to the aneurysm morphologies,these patients were divided into regular-shape and irregular-shape groups (n=56).The influences of age,gender,hypertension and aneurysm lesions of the patients in aneurysm morphologies were analyzed.Results Gender,age and hypertension were not the independent influence factors of aneurysm morphologies,while aneurysm lesions could significantly affect the aneurysm morphologies,being the independent influence factor of aneurysm morphologies (P=0.005).In the comparison of different distributions of tiny aneurysms,the intemal carotid artery and vertebral basilar artery had less irregular aneurysms than anterior communicating artery; the morphologies of small aneurysms in the anterior cerebral artery,posterior communicating artery and middle cerebral artery showed no significant differences as compared with those in the anterior communicating artery,which tended to having irregular shapes.Conclusion The aneurysm lesions are related to the aneurysm morphologies; anterior communicating artery is prone to having irregular-shape aneurysms.

Objective To explore the effect of Willis circle variation and hemodynamic forces alteration arised from vascular structural abnormity on intracranial aneurysm (IA) rupture using 3D-digital subtraction angiography (DSA) and transcranial color Doppler (TCCD) detection.Methods Two hundred and twenty-three patients with IA,admitted to and conformed by DSA in our hospital from November 2010 to November 2011,were divided into ruptured IA group (n=182) and un-ruptured IA group (n=41).The 3D-DSA was applied in all patients to carefully evaluate the aneurysm sizes,locations,and morphous features,and to confirm the presence of A1 dominance and Willis circle variation.Moreover,aneurysmal neck area,diameter of parent artery,angle between A2 segments of bilateral anterior cerebral artery,angle between aneurysmal longitudinal axis and parent artery,aortic diameter (AD) and aspect ratio (AR) were measured with assistance of 3D-DSA images.Besides,TCCD was applied to all patients,and the hemodynamic parameters were recorded to calculate wall shear stress (WSS) and mechanical stretch.The risk factors of IA rupture were analyzed by receiver operating characteristic (ROC) curve and multivariate Logistic regression with emphasis on Willis circle variation and hemodynamic forces alteration.Results Whether it was in ruptured IA group or in un-ruptured IA group,the incidence rate of variation of anterior Willis circle was higher than that of variation of posterior Willis circle.A1 dominance on the left side was the most common asymmetry.As compared with those in un-ruptured IA group,statistically elder age,smaller AD,larger angle between aneurysmal longitudinal axis and parent artery,decreased WSS and increased mechanical stretch in the ruptured IA group were noted (P＜0.05).ROC curve indicated that angle between aneurysmal longitudinal axis and parent artery,AD,WSS and mechanical stretch could be used to evaluate IA rupture (area under the curve:0.606、0.618、0.396、0.637).Age (OR=8.618,95％CI:2.866-25.917,P=0.000),hypertension (grade Ⅲ OR=16.320,95％CI:1.628-163.556,P=0.018),angle between aneurysmal longitudinal axis and parent artery (OR=3.053,95％CI:1.131-8.242,P=0.028),AD (OR=5.638,95％CI:1.507-20.251,P=0.008) and mechanical stretch (OR=4.230,95％CI:1.554-11.516,P=0.000) were risk factors of IA rupture.A1 dominance (OR=0.242,95％CI:0.074-0.785,P=0.018),small aneurysms (2-5 mm,OR=0.207,95％CI:0.054-0.788,P=0.002) and WSS (OR=0.021,95％CI:0.060-0.672,P=0.009) were identified as protective factors.Conclusions Willis circle variation exists in IA patients.Age,hypertension (grade ⅢD,angle between aneurysmal longitudinal axis and parent artery,AD and mechanical stretch are risk factors of IA rupture,while A1 dominance,small aneurysm (2-5 mm) and WSS are identified as protective factors.Accurate assessment of these factors is of great clinical significance for the prevention and treatment of IA in the future.
