两种组织工程化人工肋骨支架材料的制备及体内外降解实验研究

目的选择组织工程界常用的聚乳酸-羟基乙酸共聚物／羟基磷灰石（PLGA／HA）与多孔磷酸钙（CPC）两种支架材料,通过体内外降解实验筛选出更为符合组织工程化人工肋骨支架的材料。方法将PLGA／HA（PLGA／HA组）和CPC（CPC组）两种材料分别进行体外实验和动物体内实验,体外实验：将同等大小的PLGA／HA和CPC材料浸入0．9％NaCl溶液,并保持无菌,放入37℃温箱内,分别于2、4、8、12和24周时取出称重,比较两种材料在体外的降解速度差异;体内实验：将同等大小的PLGA／HA和CPC材料各2片分别植入20只新西兰大白兔脊柱两侧的皮下,于2、4、8、12和24周取出称重,各时间点分别处死4只大白兔;材料周围组织送组织学检查及扫描电子显微镜观察。结果薄层CT扫描（Micro—CT）和扫描电子显微镜观察结果,CPC组较PLGA／HA组具有较好的三维结构（1101．2228±0．6184mg／ccm vs．1072．5523±0．7442mg／ccm）及孔隙率（70．26％±0．45％ vs．72．82％±0．51％）;体外实验显示：两组材料在体外降解速度均较慢,至6个月时才有明显的降解,其中PLGA／HA组降解相对较多,降解了60％;体内实验显示：PLGA／HA组降解比体外更快,3个月时已基本降解完,比CPC组降解快,降解了96％;另外CPC组材料周围的炎症反应明显比PLGA／HA组轻,更适合细胞的生长和黏附。结论对再生时间较长的长段肋骨缺损,CPC比PLGA／HA更适合。     

过度训练对大鼠血清CK、LDH、SOD、SDH活性及UMb含量影响的研究

对游泳过度训练的SD大鼠血清肌酸激酶(CK)、乳酸脱氢酶(LDH)、琥珀酸脱氢酶(SDH)、超氧化物歧化酶(SOD)活性及尿肌红蛋白(UMb)的含量进行了测试分析。结果表明,一般运动训练组血清CK、LDH、SOD、SDH活性较对照组分别升高了16.31%(P＜0.01）、19.11%(P＜0.001）、51.14%(P＜0.01）、53.20%(P＜0.001）;过度训练组上述指标分别较对照组升高了55.43%、59.21%、99.90%和104. 00%（P值均小于0.001）。本文提示,一般运动训练可影响机体细胞供能代谢及细胞膜系统功能状态,过度训练可导致骨骼肌等器官发生运动性损伤。

Effects of AMP579 and adenosine on L-type Ca^2＋ current in isolated rat ventricular myocytes

Aim: To compare the effects of AMP579 and adenosine on L-type Ca^2 current (ICa-L) in rat ventricular myocytes and explore the mechanism by which AMP579 acts on ICa-L.Methods: ICa-L was recorded by patch-clamp technique in whole-cell configuration. Results: Adenosine (10nmol/L to 50μmol/L) showed no effect on basal ICa-L, but it inhibited the ICa-L induced by isoproterenol 10nmol/L in a concentration-dependent manner with the IC50 of 13.06μmol/L. Similar to adenosine,AMP579 also showed an inhibitory effect on the ICa-L induced by isoproterenol.AMP579 and adenosine (both in 10μmol/L) suppressed isoproterenol-induced ICa-L by 11.1% and 5.2%, respectively. In addition, AMP579 had a direct inhibitory effect on basal ICa-L in a concentration-dependent manner with IC50(1. 17μmol/L). PD116948 (30μmol/L), an adenosine A1 receptor blocker, showed no action on the inhibitory effect of AMP579 on basal ICa-L. However, GF109203X (0.4μmol/L), a special protein kinase C (PKC) blocker, could abolish the inhibitory effect of AMP579 on basal ICa-L. So the inhibitory effect of AMP579 on basal ICa-L was induced through activating PKC, but not linked to adenosine A1 receptor. Conclusion:AMP579 shows a stronger inhibitory effect than adenosine on the ICa-L induced by isoproterenol. AMP579 also has a strong inhibitory effect on basal ICa-L in rat ventricular myocytes. Activation of PKC is involved in the inhibitory effect of AMP579 on basal ICa-L at downstream-mechanism.

Spinal Cord Injury: How Could Acupuncture Help?

Spinal cord injury (SCI) is one of the most common causes of death and disability worldwide, and it can result in both permanent disability and serial complications in patients. Research shows that patients with SCI complications are often interested in acupuncture for symptomatic relief. Therefore, the issue of physicians advising their patients regarding the use of acupuncture to alleviate SCI complications becomes pertinent. We review and summarize two types of relevant publications: (1) literature concerning acupuncture for SCI and its complications and (2) underlying mechanisms of acupuncture therapy for SCI. Clinical trials and reviews have suggested that acupuncture effectively manages a range of post-SCI complications, including motor and sensory dysfunction, pain, neurogenic bowel and bladder, pressure ulcers, spasticity, and osteoporosis. The effect of acupuncture on post-SCI orthostatic hypotension and sexual dysfunction remains unclear. Decreased oxidative stress, inhibition of inflammation and neuronal apoptosis, regulation of the expression and activity of endogenous biological mediators, and increased regenerative stem cell production are the possible mechanisms of acupuncture therapy for SCI. Although many limitations have been reported in previous studies, given the evidence for the efficacy of acupuncture, we recommend that physicians should support the use of acupuncture therapy for SCI complications.     

高职高专学校教师课外辅导形式探索

通过调查师生均认为应对高职高专学生进行课外辅导。但传统的课间休息、自修、晚自修时间等辅导形式已不适合新的情况,教师应充分利用手机短信、建立QQ群、校园网教学平台等现代通讯、信息技术对学生进行课外辅导。
