基于档位智能控制的城市节能照明调光系统

传统城市节能照明调光系统无法实时预测交通车流量,导致城市电能消耗量仍然较大。为此,设计基于档位智能控制模型的城市节能照明调光系统。设计城市节能照明调光系统硬件电路,并通过CC2530最小系统、控制器等外围电路完成系统硬件设计。在系统软件部分,采用档位智能控制模型预测车流量,调节城市节能照明,实现基于档位智能控制模型的城市节能照明调光系统设计。实验结果表明,文中研究的基于档位智能控制模型的城市节能照明调光系统有效减少了城市电能消耗,并降低了照明调节时长,具备实际应用意义。

腓动脉穿支皮瓣及其穿支血管超声定位的临床应用

目的应用彩色多普勒超声技术检测腓动脉穿支的分布规律和内径等参数并对其进行研究,进而探讨腓动脉穿支皮瓣的临床应用效果。方法应用彩色多普勒超声技术对15例健康志愿者双侧小腿30侧腓动脉的穿支数目、分布、类型及直径进行检测研究;术前对25例患者行腓动脉穿支精确定位并设计皮瓣修复缺损部位,术后观察不同类型腓动脉穿支皮瓣的临床效果。结果 15例志愿者双侧小腿30侧腓动脉的穿支总数为110支,其中肌皮穿支45支(占40.9%),肌间隙穿支65支(占59.1%);穿支起始处内径平均为(1.06±0.31)mm。25例患者应用腓动脉穿支皮瓣修复缺损,术后随访3～18个月,20例皮瓣完全成活,5例皮瓣出现局部坏死,其中3例采用皮肤移植修复后愈合,2例经换药后创面自愈。结论腓动脉穿支皮瓣具有稳定可靠的血管蒂,是重建软组织损伤的良好方法。

Clinical Analysis of Acupuncture Combined with Tuina in Treating Cervical Vertigo

Objective: To investigate the clinical efficacy of acupuncture combined with tuina in treating patients with cervical vertigo. Methods: According to the principle of randomization, 258 cases with cervical vertigo who met the inclusion criteria for the study were randomly divided into an observation group and a control group, with 129 cases in each. The patients in the observation group received acupuncture combined with tuina therapy, while those in the control group were just treated by the same acupuncture therapy as in the observation group. After 10-day continuous treatments, the clinical efficacies of the two groups were analyzed and compared. Results: The total effective rate of the observation group was 100%, versus 86.0% of the control group, and the difference was significant(P<0.05). After treatment, cervical range of motion(ROM) scores in both groups were statistically significantly different from those before treatment(all P<0.05); in addition, there was a statistically significant difference in inter-group comparison of ROM score(P<0.05). Conclusion: Compared with simple acupuncture treatment, acupuncture combined with tuina therapy has a better effect in improving the ROM of cervical vertigo patients, with higher clinical efficacy.
