Objective To investigate the clinical efficacy of acupuncture at Huatuo jiaji points plus point Shixuan bloodletting in treating cervical spondylotic radiculopathy.Methods One hundred patients with cervical spondylotic radiculopathy were randomly allocated to treatment and control groups, 50 cases each. The treatment group received acupuncture at Huatuo jiaji points plus point Shixuan bloodletting and the control group, acupuncture at Huatuo jiaji points alone. Plasma viscosity was measured in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There was a statistically significant pre-/post-treatment difference in plasma viscosity in the two groups (P<0.05). There was a statistically significant post-treatment difference in plasma viscosity between the treatment and control groups (P<0.05). The total efficacy rate was 94.0% in the treatment group and 84.0% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Acupuncture at Huatuo jiaji points plus point Shixuan bloodletting is an effective way to treat cervical spondylotic radiculopathy.

Objective To observe diffusion changes of epiphysis of femoral head with ischemia of difference phases by line-scan diffusion weighted imaging(LSDWI),and determine whether LSDWI can provide temporal information and severity about ischemia of epiphysis.Methods lschemia was surgically induced in one hip of each piglet(n=25)and the other hip served as a normal control.Piglets were imaged before surgery and at 3 hours,72 hours and 1,3 and 6 weeks after surgery by using LSDWI.Apparent difrusion coefficients(A DC)in epiphysis of the femoral heads were calculated.Significant difierences in ADC values between ischemia group and control group were found by using paired t-test.After scan at individual time points,5 piglets were sacrificed for histological study each time.Results The ADC value in the ischemic femoral heads f(1.22±0.37)×10-3 mm2/s]decreased significantiy at 3 hours after surgery (t=3.914,P＜0.01),compared to that in control[(1.73±0.33)×10-3mm2/s},and increased at 72 hours[(2.15±0.32)×10-3mm2/s versus(1.70±0.22)×10-3 mm2/s](t=3.348,P＜0.01).Then ADC valne kept increasing until 6 weeks after surgery[(1.61±0.27)×10-3mm2/s in ischemia side vs (1.11±0.45)×10-3mm2/s in the control](t=4.136,P＜0.01).rrhe percentage change of the ADC value significandy increased at 3 hours,72 hours,1 and 3 week(s)after the surgery(P＜0.01),compared to that at the prior neighboring time point.No significant increase in the percentage change of ADC value was found between the 3rd week and the 6th week after the surgery(t=2.29.P＞0.05).Histological examinations revealed abnormal thickening within epiphyseal cartilage,and cartilaginous islands within ossified tissues.Growth disturbante wag found in form of focal growth plate disruption.Conclusions Dynamic changes of ADC values were found with the prolonged ischemia of the femoral head by LSDWI.It could serve as a useful marker for evaluating duration and extent of ischemic epiphyseal disruption.

Objective To explore the strategy and response of medical emergency centers to unexpected disaster,such as snowstorm in 2008.Method The response of Wuxi Medical Emergency Center to the snowstorm in 2008 was retrospectivey analyzed.Results Because of the disaster response plan in advance,preparation for the ambulance,and effective integration of pre-hospital care,pre-hospital tasks were completed successfully.But there existed some unsatisfied points,such as anti-skid chains wasn't fully prepared,and affected the efficiency of emergency treatment.Conclusions The increase of government input,good preparation,emergency network construction,scientific and timely disaster response plans are key to disaster events,such as snowstorm.
