Objective To explore the pathologic changes of the opening blood-brain barrier(BBB) in the early stages of 50% TBSA scalded rabbits.Methods Ten male rabbits inflicted with 50% TBSA of Ⅲ degree were randomized into five groups: control,postburn 1 h,2 h,3 h,4 h.Brain tissues were isolated at different phases and observed in gross,by microscope and transmission electron microscope.Results Endothelial cells swelled and BBB began to open in 2 h after scald.The tight junction of endothelial cells became vague and the opening of BBB increased as lesion time prolonged.Conclusion As the lesion time prolonged,the injury of endothelial cells became more serious and the opening of BBB progressed,which resulted in the formation of brain edema.

To investigate the features of CT, ultrasonography and fundus fluorescein angiography (FFA) of morning glory syndrome, the data on CT, A/B-scan ultrasonography and fundus fluorescein angiography (FFA) were retrospectively analyzed in 8 cases of morning glory syndrome (MGS). Among those cases, 6 were examined with CT, 4 with FFA and 8 with A/B-scan ultrasonography. Results showed that the characteristics of CT, A/B-scan ultrasonography and FFA in MGS included: (1) The attachment spot of optic nerve became thin and vitreous body protruded to the posterior wall of eyeball with a spherical shape on CT image; (2) in the early period of FFA, hypofluorescence appeared on the optic, the abnormal arteriae and veins around the optic papilla were displayed clearly and in the late period, optic disc was stained with fluorescein; (3) on B-scan ultrasonogram, the vitreous cavity extended to the posterior pole and optic papilla, and projected to the basal part of muscle cones and thus the posterior part of vitreous cavity looked like an upside-down bottleneck. Sometimes the echogenic band of retinal detachment could also be seen. On A-scan ultrasonogram, both vitreous cavity and bottleneck showed no ultrasonic echoes and presented a base line without any evident wave crest. It is concluded that CT, A /B-scan ultrasonography and FFA could show the imageological features of MGS from different aspects, which helps clinicians to differentiate it from other diseases such as optic disc coloboma. CT and A /B-scan ultrasonography, in particular, are considered to be reliable imageological methods for the accurate diagnosis of MGS and are superior to the traditional techniques.

In recent years, there is increasing evidence that the pathogenesis of Parkinson's disease (PD) may involve the more generation of reactive oxygen species, and investigations on patients have shown that PD is under a status of oxidative stress. The defense against the toxic effects of reactive oxygen species is an essential task within the brain. An important component of the cellular detoxification of reactive oxygen species is the antioxidant glutathione. Consequently, it seems reasonable to propose that increase of brain concentrations of glutathione including glutathione analogs or precursors could be very effective in diminishing the cumulative effects of oxidative damage, and have been investigated as potential therapeutic targets in the treatment and prevention of PD or other neurodegenerative disease.

OBJECTIVE: To explore the effect of treating periarthritis of shoulder with manipulation through evaluating clinical reports with the theory of evidence-based medicine (EMB). METHODS: By retrieval of some main medical literature databases in the past 5 years, 242 articles on treating periarthritis of shoulder with manipulation were available. Selected by admission standard, 10 of them were evaluated with EBM theory. RESULTS: Both single-application and union-application of manipulation were effective to periarthritis of shoulder, but the evaluated articles were all low-quality articles. CONCLUSION: Because of low quality clinic test and larvaceous publication bias, the extant evidence is not enough to recommend replacing other therapeutic methods by manipulation. The low quality of evaluated articles suggests that there exist some methodology problems in the clinic test on treating periarthritis of shoulder with manipulation.

[Objective] To investigate the clinical efficacy of tacalcitol combined Halometasone sequential therapy in the patients of plaque psoriasis. [Methods] 117 cases of plaque psoriasis col ected between 2011.01 and 2013.02 were randomly divided into treatment group and control group. The treatment group were treated with tacalcitol and Halometasone therapy, and required topical use Halometasone(1 time/day) in the morning ,tacalcitol use in the evening(1 time/day) before the first 2 weeks. Continuous two weeks treatment from Monday to Friday with tacalcitol(2 times/day), Saturday and Sunday with Halometasone(2 times/day), final y the transition to be used alone tacalcitol(2 times/day) in the next two weeks of continuous treatment. Control group of pa-tients given alone Halometasone(2 times/day) for 6 consecutive weeks. Observe the adverse reactions PASI scores during and after completion of treatment within the two groups. Al patients were fol owed for three months, observed recurrence. [Results] The PASI score between two groups of patients declined during treatment, especial y at the 4th and 6th week within the treatment group. Both groups had no serious adverse reactions. In treatment group, 54 patients had effective responses, the total effective rate was 90%, significantly better than the control group(41 cases,71.9%). In the fol ow-up of 3 months, the recur-rence rate was 11.1%in the treatment group, significantly lower than the control group(31.6%). The difference of total efficiency and the recurrence rate with-in the two groups was statistical y significant. [Conclusion] Tacalcitol combined Halometasone sequential therapy of plaque psoriasis has significant clinical effi-cacy and low recurrence rate.

Objective Discussing the rationality of psychological intervening therapy in the treatment of early breast neoplasm. Methods By summarizing and reviewing 84 patients suffering from the early breast cancer between January of 2003 and December of 2005, we procured some information of their clinical manifes-tations, clinical therapy and statistic results of psychological assessment. Results By intervening the psycho-logical therapy, the patients' self-efficiency and living quality can be bettered. Conclusion Patients with early breast neoplasm need to have a comprehensive treatment with general or local therapy and individual psychologi-cal intervention. Nevertheless, it is rather practical to enhance the general level of prevention and therapy of breast neoplasm through the research of psychological problems after the operation.

Growth arrest special 5 (GAS5) is a common long non-coding RNA (lncRNA).Recent studies find that lncRNA GAS5 is down-regulated in various tumors,such as breast cancer,cervical cancer,lung cancer,gastrointestinal cancers and urologic cancers.GAS5 is closely related to the development,metastasis and prognosis of cancers,which becomes a new hotspot in cancer research.
