Safety of different acupuncture manipulations for posterior circulation ischemia with vertigo

Acupuncture at Fengchi（GB20） in the posterior neck improves vertigo.However,subarachnoid hemorrhage and spinal epidural hematoma have been reported to occur after acupuncture in the posterior neck.Therefore,in the present study,we assessed the safety of acupuncture at Fengchi.Laboratory tests and adverse event reports were used to evaluate the safety of different acupuncture manipulations for the treatment of posterior circulation ischemia with vertigo.A total of 136 patients were randomly assigned to four groups.Verum acupuncture was conducted with different needle insertion directions（contralateral paropia or prominentia laryngea） and different needle twisting frequencies（60 or 120 times/minute） at Fengchi and matching acupoints（for example,Zhongwan [CV12],Qihai [CV6],Zusanli [ST36],and Fenglong [ST40]）.The patients received 14 treatments over 3–4 weeks.Routine blood analysis,hepatic and renal function tests,urine and feces tests and electrocardiography were performed before the first treatment session and after the final session.Adverse events were recorded after every session.Of the 136 patients,120 completed the study.There were no significant differences between pretreatment and posttreatment test results in any of the groups.Only five patients suffered from minor adverse events（needling pain,slight hematoma and transient chest tightness）.No serious adverse events were found.Our results indicate that a 14-session course of needling at Fengchi is relatively safe for treating posterior circulation ischemia with vertigo.

Neoadjuvant chemotherapy for locally advanced cervical cancer reduces surgical risks and lymph-vascular space involvement

Neoadjuvant chemotherapy(NACT),which can reduce the size and therefore increase the resectability of tumors,has recently evolved as a treatment for locally advanced cervical cancer.NACT has been reported to decrease the risk of pathologic factors related to prognosis of cervical cancer.To further assess the effects of NACT on surgery and the pathologic characteristics of cervical cancer,we reviewed 110 cases of locally advanced cervical cancer treated with radical hysterectomy with or without NACT at the People's Hospital of Peking University between January 2006 and December 2010.Of 110 patients,68 underwent platinum-based NACT prior to surgery(NACT group) and 42 underwent primary surgery treatment(PST group).Our results showed 48 of 68(70.6%) patients achieved a complete response or partial response to NACT.Estimated blood loss,operation time,and number of removed lymph nodes during surgery,as well as complication rates during and after surgery were not significantly different between the NACT group and the PST group.The rates of deep stromal invasion,positive parametria,positive surgical vaginal margins,and lymph node metastasis were not significantly different between the two groups.However,the rate of lymph-vascular space involvement(LVSI) was significantly lower in the NACT group than in the PST group(P = 0.021).In addition,the response rate of NACT was significantly higher in the patients with chemotherapeutic drugs administrated via artery than via vein.Our results suggest that NACT is a safe and effective treatment for locally advanced cervical cancer and significantly decreases the rate of LVSI.

茉莉酸甲酯与水杨酸诱导的大白菜叶片与根系硫苷含量系统性变化研究（英文）

目的:通过单独或混合施用茉莉酸甲酯与水杨酸,研究两者在诱导大白菜硫苷合成方面的差异及其相互作用。创新点:试验中,首次通过混合喷施或灌施茉莉酸甲酯与水杨酸,研究两者在诱导大白菜硫苷合成过程中的相互作用。方法:试验过程中采用高效液相色谱法分析各硫苷组分的具体含量,为分析茉莉酸甲酯与水杨酸单独或混合施用在诱导大白菜硫苷合成过程中的作用奠定了基础。结论:茉莉酸甲酯与水杨酸处理后,大白菜根系比叶片积累更多的硫苷,吲哚族硫苷比其他种类的硫苷积累更快;茉莉酸甲酯诱导硫苷合成的效果好于水杨酸,而且诱导时间更长;茉莉酸甲酯与水杨酸在诱导大白菜根系硫苷合成过程中具有反协同效应。
