一种磁性易视连体式锐器盒的研制与应用

使用安全医疗器具已成为医务人员在工作情况下降低设备危害的首要防线,也是减少锐器伤的有效方法之一[1]。国内锐器盒开口狭小,易出现锐器反弹及外露。锐器盒材料不透明,缺乏可视性,投放使用中无法目测锐器盒中锐器是否达到规定的3/4容积,未及时更换锐器盒会出现锐器外露[2]。使用医用锐器盒是防止和减少锐器伤的重要措施,笔者根据长期医护工作实践研制了一种磁性易视连体式锐器盒(国家实用新型专利号:ZL 202022245843.1,简称新型锐器盒),现报道如下:1设计与制作新型锐器盒主要包括盒体、盒盖、卡箍(图1)。盒体材料为全新聚丙烯透明塑料,化学性质稳定,有较好的耐冲击性、防渗漏、防锐器穿透作用。

不可易视的“易”字

现代汉语中的 “易” 字主要是 “容易” 之义, 古汉语中的 “易” 字, 用法却比较丰富.在古代汉语中,“易” 作动词用主要是 “改变” 义, 引申为 “交换”, 由 “交换” 引申为 “替代”“蔓延” 等义; 由 “改变” 还可引申为 “修治”“耕种” 等义.“易” 作形容词 “容易” 时引申为 “和悦、 平安”“平坦” 等义, 又由“容易” 引申为动词 “轻视” 义.“易” 作名词时有 《周易》、 卜筮之象、 占卜官名、 通 “埸” 等用法.

Clinical observation on Yi Jin Jing(Sinew-transforming Qigong Exercises)plus tuina on the neck for stiff neck

Objective:To observe the effect of Yi Jin Jing(Sinew-transforming Qigong Exercises)plus tuina on the neck for stiff neck.Methods:A total of 60 patients with stiff neck who met the screening criteria were selected and randomly divided into two groups,with 30 cases in each group.Patients in the control group received tuina on the neck,30 min every time,once a day,while patients in the observation group practiced Yi Jin Jing(Sinew-transforming Qigong Exercises)plus the same tuina therapy as the control group,and Yi Jin Jing(Sinew-transforming Qigong Exercises)was conducted for more than 30 min every time,once a day.Visual analog scale(VAS)scores were observed before treatment,and after 1 time,3 times and 5 times of treatment to evaluate the degree of neck pain.Results:During the treatment,each group had 2 dropouts.After treatment,the total effective rate was 92.9%in the observation group versus 82.1%in the control group,showing a statistical significance(P<0.05).The VAS scores in the observation group at the three time points were significantly lower than those in the control group(all P<0.05).Conclusion:Yi Jin Jing(Sinew-transforming Qigong Exercises)plus tuina on the neck can effectively relieve neck pain and improve cervical range of motion in patients with stiff neck,and can achieve a better effect than tuina alone.

Clinical observation on electroacupuncture plus Yi Jin Jing(Sinew-transforming Qigong Exercises)for knee osteoarthritis

Objective:To observe the efficacy of electroacupuncture(EA)plus Yi Jin Jing(Sinew-transforming Qigong Exercises)for knee osteoarthritis(KOA).Methods:A total of 60 patients with KOA were divided into an observation group and a control group according to the random number table method,with 30 cases in each group.Patients in the observation group received the treatment of EA plus Yi Jin Jing(Sinew-transforming Qigong Exercises),while patients in the control group only received EA treatment.Both groups were treated for 5 weeks.The changes of Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)and visual analog scale(VAS)scores in the two groups were observed after treatment.Results:After treatment,the total effective rate in the observation group(92.3%)was significantly higher than that in the control group(70.0%),(P<0.05);the WOMAC and VAS scores in both groups were significantly lower than those before treatment,showing statistical significance(all P<0.01);there were significant differences in the post-treatment changes in the WOMAC and VAS scores between the two groups(P<0.05,P<0.01).Conclusion:EA plus Yi Jin Jing(Sinew-transforming Qigong Exercises)is clinically effective for KOA.This combined treatment can alleviate clinical symptoms.

Adjunctive effects of acupressure therapy on pain and quality of life in patients with knee osteoarthritis:an interventional study

Objective To investigate the effect of acupressure therapy as an adjunctive therapy to pharmacological treatment on pain and health-related quality of life(QOL)among knee osteoarthritis(KOA)patients.Methods One hundred KOA patients were recruited from the orthopedic out-patient clinic of the institute.The patients were allocated randomly(flipping-coin simple randomization method)into an intervention group(n=50)and a control group(n=50).Patients in the intervention group received acupressure therapy along with pharmacological treatment.Patients in the control group did not receive acupressure therapy but continued their pharmacological treatment.Changes in pain(visual analog scale,VAS)and QOL(short-form 36-item health survey,SF-36)scores at baseline(A0),during training session(A1),follow-up at the 3rd month after training(A2)and follow-up at the 6th month after training session(A3)were collected and examined.Multiple regression analysis was used to check the relationship between pain and SF-36 domains.Results The VAS score of participants in the intervention group decreased at A3(P=0.001).Scores of physical functioning(PF),role limitations due to emotional problems(RE)and mental health(MH)of SF-36 in the intervention group improved more as compared with the control group.Patients in the intervention group with improvement in VAS(pain)score showed greater changes in mean scores of all domains of SF-36 from baseline(all P<0.05).Except bodily pain(BP),the other domains of SF-36 were negatively correlated with pain score.Conclusion Acupressure therapy with pharmacological treatment can improve health-related QOL and pain among KOA patients.

Zero Tariffs——A Blessing or a Curse?

Opinions are split on the impact of WTO’s trillion-dollar IT trade deal on ChinaThe 54 WTO members representing major exporters of information technology（IT）products finalized a deal in Geneva on July 24 to eliminate tariffs on 201 such products,in an effort to boost global trade of goods ranging from video games to medical equipment.The agreement came as an update of WTO’s 18-year-old Information Technology Agreement（ITA）.

Can native species crucian carp Carassius auratus recognizes the introduced red swamp crayfish Procambarus clarkii？

Procambarus clarkii is native to the south-central United States （Louisiana） and northeastern Mexico, and is a highly efficient predator that poses a damager to native species after its introduction or invasion. In its natural habitat, P. clarkii consumes Carassius auratus, however, whether C. auratus recognizes P. clarkii as a predator is not yet clear. In laboratory experiments, we investigated whether experienced and inexperienced C. auratus recognize P. clarkii as a predatory threat and the specific sensory modality used by C. auratus to respond to chemical and visual stimuli from P. clarkii. In the chemical stimuli experiment, two kinds of chemical stimuli were used, water from a tub containing P. clarkii previously fed with C. auratus （C. auratus diet cues） and water from a tub containing unfed P. clarkii （P. clarkii cues）. In the visual experiment, experienced C. auratus decreased activity, but inexperienced C.auratus avoided the predator compartment. When C. auratus diet cues were presented, both experienced and inexperienced C. auratus increased the use of shelter, decreased activity in the initial response phase. Compared with the blank treatment, experienced C. auratus responded to P. clarkii cues by decreasing activity; however, inexperienced C. auratus showed no reduction in activity. C. auratus appears to recognize P. clarkii as a predator both through visual and chemical cues. Further analysis revealed that C. auratus may recognize R clarkii visually through the disturbances caused by P. clarkii movement and chemically by detecting conspecific alarm cues in the diet of P. clarkii. The results also indicate that ex- perienced C. auratus can recognize R clarkii by innate chemical cues from P. clarkii, whereas inexperienced C. auratus cannot [Current Zoology 57 （3）： 330-339, 2011].
