Technological advances in glaucoma have challenged the traditional treatment paradigm. Historically incisional surgery has been used in cases of advanced disease and/or uncontrolled intraocular pressures resistant to medical or laser interventions. More recently, perhaps due to advancements in imaging, surgery has been suggested to be beneficial earlier in the treatment paradigm. Despite these trends, surgical manipulation of the tissues and unpredictability of wound healing continue to result in surgical failure. Magnesium is an essential element for human body and plays a critically important role in maintaining the functional and structural integrity of several tissues, including the eye. Due to several of its advantageous properties such as non-toxicity, biodegradability, and high biological compatibility, magnesium alloy has attracted great attention as a novel biomaterial. Biodegradable cardiovascular stents made of magnesium alloy have already been introduced into clinical practice. The purpose of this review is to determine if bioabsorbable magnesium alloys can be utilized as a promising candidate for the development of a new generation of glaucoma surgical assistive devices.

In practice,since the measurement environments are usually complex,the electromagnetic interference problem has been an important issue for sensor applications,and the fiber sensor can overcome it *** paper proposes a new type of vibration sensor based on fiber Bragg grating(FBG).The vibration sensor with double equal strength cantilever beams structure can further improve the measurement *** physical model of FBG vibration sensor was established,and the structural parameters of the double equa-strength cantilever beams were designed and optimized by finite element *** simulation and experimental tests are included in this paper to illustrate the low-frequency vibration performance of the designed vibration ***,the sensitivity of the sensor was 0.0240 pm/(m·s^(-2)),the natural frequency was 185 Hz,and the linearity was obtained,which further verify the stability and reliability of the sensor vibration frequency measurement.

Heart failure （HF） is a potentially fatal disease that affects increasing number of people worldwide. Although heart transplant is the ＂gold standard＂ therapy for HF, due to the limited availability of organs, many patients died when waiting for the transplant. Left ventricular assist device （LVAD）, as a mechanical circulatory support, has become a new light for patients with HF. With the technical advancements, LVADs work not only as a bridge to transplant, but also assist heart recovery and even as a destination therapy in long-term treatment. This observation paper reviewed the development of LVAD and its clinical roles. The challenges and possible solutions in nursing care for pa- tients with LVAD at different stage of implantation were discussed. The healthcare professionals could obtain a better understanding about the LVAD treatment for HF patients.

AIM: To evaluate the tissular expression of Androgen (A), Estrogen (E) and Progesterone (Pg) receptors, and Apolipoprotein D (ApoD), in liver tumors from resected hepatocellular carcinoma (HCC) cases in order to assess their possible relationship to prognosis. METHODS: We performed an immunohistochemical study using tissue microarrays (containing more than 260 cancer specimens, from 31 HCC patients and controls) to determine the presence of specif ic antibodies against AR, ER, PgR and ApoD, correlating their findings with several clinico-pathological and biological variables. The staining results were categorized using a semi-quantitive score based on their intensity, and the percentage of immunostained cells was measured. RESULTS: A total of 21 liver tumors (67.7%) were positive for AR; 16 (51.6%) for ER; 26 (83.9%) for PgR and 12 (38.7%) stained for ApoD. We have found a wide variability in the immunostaining score values for each protein, with a median (range) of 11.5 (11.5-229.5) for AR; 11.1 (8.5-65) for ER; 14.2 (4-61) for PgR; and 37.7 (13.8-81.1) for ApoD. A history of heavy ethanol consumption, correlated positively with AR and PgR and negatively with ER status. HCV chronic infection also correlated positively with AR and PgR status. However, the presence of ApoD immunostaining did not correlate with any of these variables. Tumors with a positive immuno-staining for PgR showed a better prognosis. CONCLUSION: Our results indicate a moderate clinical value of the steroid receptor status in HCC, emphasizing the need to perform further studies in order to evaluate the possible role of new hormonal-based therapies.

吲哚美辛(Indomethacin)广泛地应用于治疗风湿性关节炎,关节僵硬性脊椎炎,骨关节炎及急性痛风样关节炎。但在较高血药浓度时会产生与胃肠道、中枢神经系统有关的副作用,其应用受到严重限制。本研究是通过将吲哚美辛与PEG6000制备成固体分散体,然后和聚丙烯酸树脂压制成骨架片,以便一方面减少其副作用,另一方面达到预期的释药模式,从而发挥其优良的治疗作用。吲哚美辛在水中不溶,并具有多晶型,会严重改变其释药特征,而固体分散体恰能克服这些缺点。聚丙烯酸树脂型骨架片的孔隙率及曲率能控制其释药。
