ObjectiveTo explore the clinical effectiveness of intralesional glucocorticoid therapy on infantile hemangioma in proliferative stage,and variance of vascular endothelial growth factor(VEGF) expression in the hemangioma tissues.MethodsExperimental group:5 cases were injected with triamcinolone acetonide 3 days before operation,5 cases were done 6 days before operation,5 cases were done 9 days before operation and 5 cases were done 2 weeks before operation(the dose of injection was 1 mg/cm2 per time,but not exceeding 2 mg/kg).Control group:5 infantile hemangioma cases in involuting stage and 5 infantile hemangioma cases in proliferative stage did not received any therapy.The specimen of the hemangioma were collected to detect the expression of VEGF by two-step immunohistochemistry.Every optical slice was detected by 5 campus visualis of high power lens.ResultsObserving the specimen dyed by HE in the light microscope,there was no significant difference between injected group and non-injected group.But by means of immunohistochemistry,the expression of VEGF could been down regulation by the glucocorticoid(F=17.919 1P

Sepsis may result in a high mortality.Fish oil,which riches in ω-3 polyunsaturated fatty acids.has anti-inflammatory and immune regulatory functions.ω-3 fatty acids,which are special immune nutrient substrates,participate in the energy provision as well as improve organ function and regulate proinnammatory/anti-inflammatory cytokines.The ideal function of fish oil is associated with dosage,time of initiation and duration of application.

BACKGROUND:Cervical single-door laminoplasty for chronic compressive myelopathy has obtained exact effects. To reduce the occurrence of related complications, different doctors have proposed different improvement programs, and have achieved a certain effect, but the effect on postoperative complications is not very wel. OBJECTIVE:To evaluate the effect of modified open-door laminoplasty with steel implantation and preservation of bilateral semispinalis. METHODS: We retrospectively analyzed the data of 30 cases of multilevel cervical spondyiotic myelopathy who underwent modified open-door laminoplasty from October 2013 to March 2014. Internal fixation material was Centerpiece titanium plate fixation system. Visual Analogue Scale score, Japanese Orthopaedic Association score (17-score method), neck disability index, range of motion of cervical vertebra, and cervical curvature were compared before treatment and during folow-up. Axial symptom severity was assessed after treatment. RESULTS AND CONCLUSION:The patients were followed up for 12-24 months. No complications appeared during repair, including postoperative spinal cord injury, cerebrospinal fluid leakage, infection or C5 nerve root palsy. Only one patient suffered from axial pain, but there was no need for oral medication. The improvement rate of Japanese Orthopaedic Association score was (76.96±17.61)%. Neck disability index decreased from 12.29±3.82 preoperatively to 8.24±2.86 in final follow-up. Range of motion of cervical vertebra (47.41±17.33)° in final follow-up, accounting for (93.0±4.2)% of preoperative data. Cervical curvature decreased from (13.47±10.54)° preoperatively to (12.88±8.56)° in final follow-up. These findings confirm that modified open-door laminoplasty with preservation of bilateral semispinalis can reserve cervical rear structure to maximum extent, is conducive to early functional exercise after rehabilitation, and reduces the incidence of axial symptoms and loss of cervical curvature.

Objective To investigate the serum level of C reactive protein(CRP) in the hypertension patients with heart function impairment.Methods 68 hypertension patients who had no,mild or severe heart function impairment were se- lected and accordingly divided into 3 groups,while 30 healthy subjects served as normal controls.The levels of HS-CRP and LVEF was measured.Results All the hypertension patients had a high CRP level than normal controls(P

Objective: To compare the effects of engine-driven rotar y nickel-titanium(ni-ti) file and stainless steel hand K-file (ss-K-file) in posterior teeth’s root canal preparation. Methods: 118 root c anals of 45 cases were instrumented with ni-ti file (ProFile)by crow-down te chnique and 127 root canals of 49 cases were treated with ss-K-file by step- back technique respectively. The incidence of pain after preparation and the res ults of obturation were observed. Results:Total pain incidence i n ni-ti file preparation group and in ss-K-file group was 20.00% and 46.94% respectively (P

Objective To estimate the diagnostic value of dual-energy CT in gouty arthritis.Methods English and Chinese litera-tures publicated before May 2014 were searched in PubMed,Embase,Cochrane and Wanfang database.Available literatures were selected according to the inclusion and exclusion criterias.Sensitivity,specificity with 95% confidence interval (95% CI)was pooled with bivariate random-effects model.Hierarchical weighted symmetric summary receiver-operating curve (HSROC)was also used in estimating.Meta-regression and sensitivity analysis were used to explore the potential sources of heterogeneity.Results Nine studies were included in the analysis.The pooled sensitivity,specificity and 95% CI were 92%(84-96%)and 88%(83-92%)respectively, area under the HSROC curve was 0.91 (0.88-0.93).There was substantial heterogeneity between studies(I 2 =85%).Conclusion Dual-energy CT is accuracy in diagnosing gouty arthritis.The sources of heterogeneity was not been explored.

With the progress of human civilization,the harmonious development of society is gradually realized by different researchers.Medicine,as a science directly serving humans,emphasizes more on humanism than other sciences.Medical research is not only characterized by scientificity and innovativeness,but also by ethicality.More and more biomedical journals are paying attention to issues of ethics.This review discussed the ethical issues in academic medical writing based on the Uniform Requirements for Manuscripts Submitted to Biomedical Journals published by International Committee of Medical Journal Editors (ICMJE) and the discussions by Committee on Publication Ethics (COPE).

Osteoblasts are the most important mechanoreceptive and osteogenic cells.The loss of bone in microgravity is mainly due to the dysfunction of osteoblasts.Research on osteoblast cytology under simulated weightlessness has made great progress in recent years.Current experiments are focusing on the changes in the cellular proliferation,differentiation,apoptosis, function and signal transduction in osteoblasts.This paper reviews the progress of the studies in this field.
