Objective To study the protective effects of Tianma xingnao capsule on brain blood circulation in mice and rats.Methods The arteria carotis externa was ligated,and arteria carotis interna was kept.The left carotid artery was exposed and placed over an ultrasonic flow probe.The brain flow volume was recorded with an Ultrasonic Volume.The pursiness time of mice was observed to evaluate the effect of Tianma xingnao capsule on cerebral ischemia and anoxia.The permeability of normal blood-cerebral barrier was investigated in mice.Results Tianma xingnao capsule significantly increased brain blood flow and prolonged mouse pursiness time.Tianma xingnao capsule at a dose of 4 g/kg significantly elevated the content of Evans in mouse brain.Conclusions Tianma xingnao capsule can increase the brain blood flow in rats and improve brain blood circulation in mice.It is obviously advantageous to protect against cerebral ischemia and hypoxia.

Acupuncture therapy needs to cause enough somatosensory stimulation to achieve therapeutic effect.How to identify the site and depth before acupuncture,assess therapeutic effect after acupuncture and ensure the safety of treatment are the points for clinical application of acupuncture therapy,but no standard objective and quantitative access has been achieved.Under assistance of ultrasound,precise positioning before acupuncture,visualization of anatomical structures and quantification of the depth during acupuncture became feasible.The research progresses of ultrasound for assisting acupuncture therapy were reviewed in this article.

Genitourinary syndrome of menopause (GSM),is a common disease in postmenopausal women.It is reported that the incidence of GSM in breast cancer patients (79％-95％) was higher than that in normal counterparts (more than 50％).GSM significantly reduced the quality of life in breast cancer patients,but was not given enough attention,and most of breast cancer patients with GSM were not diagnosed and treated.In addition,chemotherapy and endocrine therapy for breast cancer may increase the incidence and severity of GSM.Hence,prevention and treatment of GSM should be strengthened in breast cancer patients.

Objective To observe the effect of ultrasound-guided iliopsoas plane block(IPB)on the quality of postoperative recovery in patients undergoing hip arthroplasty.Methods Sixty patients who underwent hip arthroplasty were selected,37 males and 23 females,aged 40-79 years,BMI 18-30 kg/m2,ASA physical status Ⅰ-Ⅲ.The patients were divided into two groups by random number table method:the iliopsoas plane block group(group IPB)and the femoral nerve block(FNB)group(group FNB),30 pa-tients in each group.Before anesthesia induction,IPB was performed with 0.5%ropivacaine 10 ml and lat-eral femoral cutaneous nerve block was performed with 0.5%ropivacaine 5 ml in group IPB.And FNB was performed with 0.5%ropivacaine 10 ml and lateral femoral cutaneous nerve block was performed with 0.5%ropivacaine 5 ml in group FNB.The dosages of propofol,remifentanil,and cis-atracurium during operation were recorded.The quality of recovery-15(QoR-15)scale was evaluated preoperatively and postoperatively 1 day,2 and 3 days.The max VAS(VASmax)pain score and manual muscle test(MMT)score of quadri-ceps muscle were recorded 12,24,and 48 hours after surgery.The time of getting out of bed for the first time,opioid dosage,and patient satisfaction were recorded.The incidence of nerve injury,vascular injury,puncture site infection,and local anesthetic poisoning were recorded.The postoperative complications of diz-ziness,nausea and vomiting,deep vein thromboses,and elirium were also recorded.Results There was no significant difference in the dosage of propofol,remifentanil,and cis-atracurium between the two groups.Compared with group FNB,the QoR-15 scale score in group IPB was significantly higher 1 day,2 and 3 days after operation(P＜0.05).Compared with group FNB,the MMT scores of quadriceps muscle was sig-nificantly higher in group IPB 12 and 24 hours after surgery(P＜0.05),and the first time of getting out of bed was shortened in group IPB(P＜0.05).However,there were no significant differences in the VASmax pain score,MMT score of quadriceps muscle 48 hours after surgery,opioid dosage,and patient satisfaction between the two groups.No nerve block related complications were found in both groups.There were no sig-nificant differences in postoperative complications between the two groups.Conclusion The iliopsoas plane block can improve the quality of postoperative recovery and accelerate the recovery of patients with hip re-placement,and the effect is better than that of femoral nerve block.
