Objective To study the importance of statins in the prevention and treatment of coronary heart disease.Methods167 cases of coronary heart disease in our hospital from December 2013 to November 2014 were chosen as the research object, patients were given different statins such as atorvastatin, rosuvastatin and simvastatin treatment, and total cholesterol(TC),triglyceride(TG), low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol (HDL-C)before and after treatment were statistically analyzed.Results3 months after treatment TC,TG,LDL-C,HDL-C were significantly better than before treatment(P< 0.05);3 months after treatment, 6 months and 12 months, the index value has improved, but the differencehad no statistical significance.ConclusionThe use of statins in coronary heart disease has a significant effect,can improve the clinical indicators.

Objective To evaluate the impact of multiple lacunar infarction (MLI) on the outcomes of mild cognitive impairment (MCI). Methods MCI patients were selected in outpatients and hospitalized patients using a common international standard MCI screen. Magnetic resonance imaging (MRI) and computer tomography (CT) were used to determine the presence of MLI. MCI patients were followed up for 6～24 months and their cognitive status and the impact of MLI on MCI were evaluated using Kaplan-Meier survival analysis. Results One hundred twenty patients were diagnosed as having MCI based on clinical evaluation and neuropsychological assessment. Among them, 43 (35.8%) patients had MLI and the rest 77 (64.1%) patients did not have. Twenty-seven MCI patients with MLI (62.8%) developed dementia, while 15 MCI patients without MLI (19.4%) developed dementia during 6～24 months follow-up. Kaplan-Meier analysis indicated that the incidence of dementia was significantly higher in patients with MLI than in patients without MLI did (P＜0.05). Conclusions MCI patients with MLI are more prone to dementia. These results suggest that early interventions aimed at controlling the modifiable risks are warranted for dementia prevention in MCI patients with MLI.

Objective:To investigate the clinic-cytology and histopathology of non-Hodgkin lymphoma (NHL) in breasts. Mothods:Twelve cases of NHL of the breast were studied by fine-needle aspiration biopsy (FNAC), histopathology and immunohistochemistry, and whose clinical data were analysed at the same time. Results:In 12 cases of NHL, 3 cases were T-cell NHL and 9 cases were B-cell NHL. Cytologically, the T-cell NHL cells were mostly arranging in diffuse patterns. The tumor cells were oval and pleomorphism. Some of them had distorted nucleus and thin nuclear envelope.The nucleus showed irregular course chromatin and visible nueleoic. Histopathologically, some of the tumor cells distributed around the blood vessels, and there was an obvious phenomenon of “blood-vessel-closing”. B-cell lymphoma cells were arranginy in diffuse pattern, and showed round and ellipse in shape with a clot and course granular chromatin and visible nueleoic and karyoknesis. Lymphoepithelia lesions were seen. Immunohistochemistry showed that CD3, CD43, and CD 45RO in T-cells NHL were positive.CD20, CD74 and CD79a in B-cells NHL were negative. CK, EMA, ER and PR in NHL were all negative. Conclusion:NHL of breast is extremely rare, and its definite diagnosis depends on various examination methods.

BACKGROUND:Poststroke depression is one of the most common psychological behavior disorders after stroke and its mechanism remains unclear. Studies have suggested that microRNAs (miRNAs) involved in neurogenesis and synaptogenesis may play an important role in psychology diseases. OBJECTIVE:To observe the expression of miR-137 in the blood and brain of poststroke depression rats and its effect on the behaviors of rats. METHODS:Thirty-six rats were equal y divided into six groups:control, model, agomir-137, agomir-NC, agomir-137+Grin2A and agomir-137+vector groups. Control group had no treatment. Poststroke depression models were established by ligation of middle cerebral artery and chronic mild stimulation in the latter four groups fol owed by receiving an injection of nothing, agomir-137, agomir-NC, LV-CMV-Grin2A or control plasmids into the left lateral ventricle, respectively. RESULTS AND CONCLUSION:We found significantly lower miR-137 levels in the brain and peripheral blood of post-stroke depression rats compared with normal rats. Vertical scores and horizontal scores on the behavior test were significantly higher in the agomir-137 group than the agomir-NC and model groups at 3 weeks after cerebral ischemia;while, sucrose consumption percentage was also higher in the agomir-137 group at the end of 2 weeks after cerebral ischemia. Luciferase assays showed miR-137 bound to the 3’ UTR of Grin2A, regulating Grin2A expression in a neuronal cel line. Grin2A gene overexpression in the brain of post-stroke depression rats noticeably suppressed the inhibitory effect of miR-137 on post-stroke depression. Overal , these findings show that miR-137 suppresses Grin2A protein expression through binding to Grin2A mRNA, thereby exerting an inhibitory effect on post-stroke depression and offering a new therapeutic target for poststroke depression.

OBJECTIVE: Discussing the use of endoscopy in the operation of microvascular decompression of cranial nerves to treat trigeminal neuralgia (TN), hemifacial spasm (HFS), glosspharyngeal neuralgia (GN) and some tumors of the cerebellopontine angle (CPA). METHOD: Since 2006, 973 cases (including 420 cases of TN, 487 cases of HFS, 66 cases of GN) had received the operation of nervous decompression by approach of postauricular suboccipital to the CPA. All cases who used the endoscopy and the material was described in detail. RESULT: In 420 TN patients, 390 (92.9%) were found responsible blood vessels. Two (0.5%) were found no responsible blood vessels but arachnoid adhesion, 28 were found CPA tumor secondary trigeminal neuralgia. In 487 HFS patients, 486 were found responsible blood vessels. Between the vascular and trigeminal nerve, teflon was used to decompress and isolate the facial nerve. In 66 GN, the glossopharyngeal nerve were cut and vagus nerve were decompressed. The short-term cure rate was 100%. Cerebrospinal fluid rhinorrhea occurred in 3 cases, 1 case of cerebellar infarction, 2 patients of cerebellar hemorrhage, 2 cases of pneumatosis. All complications were cured at last. There were no deaths. All cases were followed-up for 1 to 5 years. Four cases of TN and 4 cases of HFS recurrent, and none of GN recurrence. CONCLUSION The microneurosurgery of nervous decompression endoscopy technology for the treatment of TN, HFS, GN and some tumors of the CPA is an ideally functional and etiotropic operation. It is helpful to detect the responsible blood vessel and to protect the brain tissue and nerve function with endoscope, which can improve the success rate of the operation and avoid the complications. This technology has clinical application value.

OBJECTIVETo compare the fracture resistances of pulpless teeth restored with FRC (Fiber Reinforced Composite) posts and three kinds of resin core material.

METHODSA total of 42 recently extracted upper incisors were randomly divided into 3 groups. Group A was restored with prefabricated glass-fiber posts and Artglass polymer core; group B with prefabricated glass-fiber posts and Charisma composite resin core; and group C with prefabricated glass-fiber posts and AB composite resin core. In every group, the core material was processed by hot-press and non hot-press respectively. The posts size and shape were identical in the 3 groups. All teeth were fully covered with polycarbonate resin crowns. Fracture resistance was measured by applying point force at 130 degrees to the long axis of the teeth on an universal testing machine.

RESULTSMean fracture threshold was 505.4 N +/- 42.0 N and 564.1 N +/- 41.7 N in group A, 411.3 N +/- 23.3 N and 315.3 N +/- 19.1 N in group B and 358.4 N +/- 36.1 N and 423.4 N +/- 47.5 N in group C. In all groups, there was no posts fracture and polycarbonate resin crowns fragmentation.

CONCLUSIONThe composite restoration of FRC posts combined with resin core and resin crown can improve the fracture resistance of the pulpless roots. The strength of resin core material can be increased by hot-press methods.

BACKGROUNDAlthough biomedical ontologies have standardized the representation of gene products across species and databases, a method for determining the functional similarities of gene products has not yet been developed.

METHODSWe proposed a new semantic similarity measure based on Gene Ontology that considers the semantic influences from all of the ancestor terms in a graph. Our measure was compared with Resnik's measure in two applications, which were based on the association of the measure used with the gene co-expression and the protein-protein interactions.

RESULTSThe results showed a considerable association between the semantic similarity and the expression correlation and between the semantic similarity and the protein-protein interactions, and our measure performed the best overall.

CONCLUSIONThese results revealed the potential value of our newly proposed semantic similarity measure in studying the functional relevance of gene products.
