Objective To investigate the expression of 5-lipoxygenase activating protein gene (ALOX5AP) polymorphism in the patients with cerebral infarction,and explore its relationship with cerebral infarction susceptibility.Methods Patients with cerebral infarction and healthy volunteers were selected for this study,whose venous blood was extracted and detected with polymerase chain reaction/restriction fragment length polymorphism (PCR-RFLP).Haplotype A (SG13S114T,SG13S89G,SG13S32A,SG13S25G),haplotype B (SG13S377A,SG13S114A,SG13S41A,SG13S35G),and their nucleotide polymorphism loci were observed.Results Single nucleotide polymorphism (SNP)-SG13S114,SNP-SG13S32 and HapA carrying rate were significantly different between patients with cerebral infarction and healthy volunteers (P <0.05).SNP-SG13S114 and SNP-SG13S32 were independent risk factors of cerebral infarction (OR > 1.0,P < 0.05).Conclusions The morbidity of cerebral infarction in Wenling City was influenced by SNP-SG13S114,SNP-SG13S32,and HapA carrying rate.

Objective To evaluate atrial septal defect (ASD) occlusion employing a small right anterior thoracotomy approach. Methods A total of 21 patients with ASD underwent general anesthesia and 2 -3 cm incision was made in the fourth right intercostal space. Utilizing transesophageal or transthoracic echocardiography, the occluder was released using a monotube unit. Results All patients were occluded successfully. No patient required open surgery utilizing extracorporeal circulation. There were no major complications and no evidence of residual atrial shunt. Conclusion ASD occlusion via a minimal surgical incision is safe, less invasive, and has excellent outcomes.

Abstract: Objective To investigate the clinical characteristics and diagnosis key points of brain abscess caused by Nocardia asiatica, and provide a clinical basis for diagnosing and treating intracranial infection caused by Nocardia. Methods A case of pulmonary Nocardia asiatica complicated with brain abscess diagnosed at the Second Affiliated Hospital of Hainan Medical University was selected to analyze the clinical manifestations, cerebrospinal fluid characteristics, pulmonary and cranial imaging features, and treatment plan, and to summarize the diagnosis and treatment experience. Results The patient was an elderly woman with a history of diabetes, dry cough was the first symptom without fever or headache. At the beginning of the course, it was diagnosed as pulmonary infection and tuberculosis in the local hospital, and received conventional antimicrobial and anti-tuberculosis therapies, but showed no improvement. The patient developed progressive limb weakness, followed by consciousness disorders, and coma. Cerebrospinal fluid (CSF) adenosine deaminase and lactate dehydrogenase were not abnormal, CSF pressure, protein and white blood cells were high, mainly with multiple nuclear cells. CSF glucose and chloride were normal in the early stage of the disease, but decreased significantly in the later stage. Metagenomic analysis of cerebrospinal fluid indicated Nocardia asiatica with a specific sequence number of 537. Lung CT showed exudation, abscess, and cavity in the right lung. Skull MRI scan + enhancement suggested multiple scattered abscesses in both cerebral hemispheres. The abscesses were of different sizes and showed ring enhancement, with extensive surrounding edema, and ventricular compression. After treatment with meropenem, linezolid, and compound sulfamethoxazole tablets, the cerebrospinal fluid recovered, and the lesions in the lungs and intracranial structures improved. Conclusions Brain abscess caused by Nocardia asiatica is similar to the tuberculous brain in clinical symptoms, cerebrospinal fluid examination, craniocerebral imaging, so we should be alert to the possibility of Nocardia infection in patients with diabetes. At the same time, metagenomic testing of the cerebrospinal fluid can help confirm the diagnosis. The mortality and disability rates of brain abscess caused by Nocardia are high. Early diagnosis and treatment can improve the prognosis.

The desired DNA product of KGPcd and KGP-hag was obtained from the total DNA of Porphyromonas gingivalis by PCR with two pairs of gene specific primers. The segment of KGPcd and KGP-hag (about 1.5kb and 1.6kb) was inserted into pGEM-T easy Vector. The double-stranded DNA of the postitive clone was analyzed by restriction endonuclease mapping and DNA sequenceing. The sequences of KGPcd and KGP-hag were consistent with those of the references appeared. The proteins of KGPcd and KGP-hag will be obtained for further study.

Objective To create a model with simple expression of mechanical characteristics of the human chest for the development of a manikin. Methods A simplified Gruben-model was proposed based on the anatomical structure and physical characteristics of the materials, and perfect coefficients were computed. The model feasibility was proved by the coefficient of determination and residual analysis.Results The mathematic form of the model provided had three fewer terms than Gruben′s. The coefficient of determination approximated 1, the residue was small, and the perfect coefficients of "a typical human" were determined.Conclusion The hypothesis of the model makes the coefficients physically meaningful, which provides a new method to study the force-displacement relationship of the thorax. Also the simple form makes it easy to create the model and provide some guidance for the design of a manikin′s chest.

Background The neovascular form of the disease usually causes severe vision loss in a number of eye diseases.Special-domain optical coherence tomography (SD-OCT) provides high-quality in retinal imaging and the possibility of the measurement in vivo.Objective This study aimed to investigate the feasibility of SD-OCT dynamically measuring choroidal neovascularization (CNV).Methods CNV was induced in 30 left eyes of 30 clean Brown Norway(BN)rats by retinal photocoagulation with the laser parameter as follows: wavelength 532 nm,exciting power 200 mW,spot diameter 100 μm and irradiating time 50 ms.Bubble or less retinal bleeding was thought as Brunch membrane breakage and CNV model establishment.Fundus fluorescein angiography(FFA) was performed to determine the establishment of CNV model and scored based on the fluorescein leakage on 3,7,14,21 days after photocoagulation.Meanwhile,CNV memberane thickness (CMT) was dynamically measured in vivo as the maxiume value from retinal inner limiting membrane through choroidal vessel layer in various time points.Histopathologic examination was used in the 14th day to evaluate and verify the result of SD-OCT.The right eyes were as controls.Results FFA examination showed that disc-like leakage of fluorescein appeared in 7 days and extended in 14 days after photocoagulation with the scores of 1.6±0.4,2.5±0.6 and 2.4±0.5 in 7,14 and 21 days,showing a significant difference among them(F=13.11,P<0.01).The fluorescein leakage score was significantly higher in 14 and 21 days than that of 7 days(both P<0.05).CMT measured by SD-OCT was(76.33±10.09),(102.03±14.21)and(98.03±13.76) μm in 7,14 and 21 days after photocoagulation respectively,with a significant difference among 3 time points (F=23.25,P<0.01),and that in 14 and 21 days was significantly declined in comparison with 7 days(both P<0.05).The results of SD-OCT showed a consistent tendency with that of FFA.Histopathological examination showed CNV formation in 14 days after photocoagulation.Conclusions Experimental CNV model was successfully induced by laser photography.SD-OCT technology allows excellent visualization of CNV in vivo.
