ObjectiveTo explore the therapeutic mechanism of Bushen Huoxue prescription from the perspective of bone metabolism by observing the clinical efficacy of this prescription in treating femoral head necrosis （ONFH， syndrome of liver and kidney deficiency） and its influences on bone metabolism indexes： N-terminal propeptide （PINP） and β-collagen degradation product （β-CTX）. MethodSixty-six ONFH patients with the syndrome of liver and kidney deficiency in Zhengzhou Traditional Chinese Medicine Hospital of Orthopedics from December 2021 to September 2022 were selected. The patients were randomized into an experimental group and a control group by the parallel control method， with 33 patients in each group. The experimental group received Bushen Huoxue prescription orally， while the control group received Xianlinggubao Capsules orally， with a treatment cycle of 6 months. The visual analogue scale （VAS） score， Harris score， Association Research Circulation Osseous （ARCO） staging， imaging changes， quantitative scores of TCM symptoms， and serum levels of PINP and β-CTX were determined before and after treatment. The occurrence of adverse events and reactions was recorded. ResultThe total response rate in the experimental group was 83.87% （26/31）， which was higher than that （68.75%， 22/32） in the control group （Z=-2.096， P<0.05）. After treatment， the single and total scores of TCM symptoms， VAS score， and β-CTX level decreased in the two groups （P<0.05）. Moreover， the decreases in the scores of hip pain， lower limb mobility， soreness of waist and knees， and lower limb flaccidity， total score of TCM symptoms， VAS score， and β-CTX level in the experimental were larger than those in the control group （P<0.05）. After treatment， the imaging results showed no significant improvement in the two groups. The Harris score and PINP level in both groups increased after treatment （P<0.05）， and the increases were more obvious in the experimental group than in the control group （P<0.05）. No serious adverse event or adverse reaction appeared during the observation period. ConclusionBushen Huoxue prescription can relieve pain and TCM symptoms and improve the hip joint function in treating ONFH patients with the syndrome of liver and kidney deficiency. It can inhibit the development of ONFH， increase PINP， and decrease β-CTX. No obvious side effect appears during the clinical observation period， which shows that Bushen Huoxue prescription has good safety.

Investigation and analysis of cognition and clinical practice status of ERAS among anesthesiologists in secondary hospitals in China / 中华麻醉学杂志

Objective:To investigate the cognition and clinical practice status of Enhanced Recovery After Surgery (ERAS) among anesthesiologists in secondary hospitals in China using a questionnaire, trying to provide some references for the promotion and popularization of ERAS across China.Methods:From April to November 2021, anesthesiologists in secondary public hospitals across the country were enrolled by convenience sampling and investigated by a self-designed questionnaire on the cognition, clinical practice status and their teaching needs about ERAS.Influencing factors of ERAS cognition were then analyzed.Results:Totally 879 questionnaires were sent out, 864 were effectively received with effective recovery of 98.3%.The anesthesiologists in this survey were distributed in 31 provincial administrative regions across the country.The score of the ERAS cognition (total score of 18) was 12.00 (3.75), and 563 participants (65.2%) were qualified on cognitive status (score ≥ 12). Geographic region, age, educational qualification, professional title and length of occupation were found to have significant influence on ERAS cognition ( P<0.05). Among the anesthesiologists who participated in the survey, 817 participants (94.6%) recognized that ERAS management was beneficial to patients, and 778 (90.0%) of them agreed that ERAS management should be carried out as much as possible in secondary hospitals.Two hundred and fifty-five (29.5%) participants had never implemented ERAS management in clinic anesthesia.There were significant differences in the ERAS practice status among participants from different geographical regions in China ( P<0.05). Eight hundred and forty-eight (98.1%) anesthesiologists who participated in the survey expressed their willingness to receive further systematic training on ERAS, and taking online courses and reading books were the current main ways to obtain related knowledge. Conclusions:The cognition and clinical practice status of ERAS need to be improved among anesthesiologists in secondary hospitals in our country.Sustained ERAS education programs with various forms should be carried out in subgrade medical care centers in order to continuously promote the extensive practice of ERAS across China.

Perioperative blood management of patientswith Marfan syndrome undergoing scoliosis surgery / 基础医学与临床

Objective To investigate the anesthesia and perioperative blood management of patients with Marfan syndrome (MS) undergoing scoliosis surgery.Methods The clinical data of MS patients underwent scoliosis surgery from January 2013 to December 2015 in Peking Union Medical College Hospital were collected and compared with patients received the same surgery but without MS.Perioperative information and data on anesthesia and blood management were analyzed.Results Compared with control group,MS patients were found with more preoperative comorbidities with statistical significance,including eye disease,echocardiographic abnormalities,and ventilatory defects.MS patients had significantly more blood loss,more intraoperative and postoperative allogeneic and autologous blood transfusion.The operation time,anesthesia time,and length of postoperative hospital stay were all significantly longer in MS patients.Conclusions MS patients are common with multi-system involvement and comorbidities.Considering the high risk of perioperative bleeding,the anesthesia and blood management for MS patients undergoing scoliosis surgery should be with extra caution.Blood management should be applied and appropriate invasive monitoring methods should be considered when necessary.

Anesthetic management of patients with active infective endocarditis undergoing cardiac valve surgery under cardiopulmonary bypass / 中华麻醉学杂志

Objective To summarize experience and characteristics of the perioperative anesthetic management of patients with active infective endocarditis (AIE) undergoing cardiac valve surgery under cardiopulmonary bypass (CPB).Methods A total of 117 patients of both sexes,aged 18-70 yr,of American Society of Anesthesiologists physical status Ⅱ-Ⅳ,undergoing cardiac valve surgery under CPB from January 2014 to June 2015 in Peking Union Medical College Hospital,were enrolled in the study and divided into AIE group (n =57) and non-AIE group (n =60).Anesthesia was induced by Ⅳ injection of midazolam 1-2 mg,etomidate 0.15-0.30 mg/kg,sufentanil 0.3-0.5 μg/kg and rocuronium 0.6-1.0 mg/kg.After orotracheal intubation,the patients underwent high-frequency volume-controlled ventilation with low tidal volume,and positive end-expiratory pressure was increased appropriately.Esophageal echocardiography was used for evaluation.Anesthesia was maintained by inhalation of 1.0％-1.5％ sevoflurane,intermittent Ⅳ boluses of sufentanil 0.2-0.3 μg/kg and Ⅳ infusion of piperium bromide 2 mg/h,and the bispectral index value was maintained between 40-60 during surgeDy.Sensitive antibiotics were given during surgery according to the results of preoperative blood culture in AIE group.The following data were collected:baseline patient characteristics,preoperative blood routine,erythrocyte sedimentation rate,concentrations of hypersensitive c-reactive protein and amino-terminal pro-brain natriuretic peptide,operation time,CPB time,intraoperative consumption of vasoactive drugs,fluid intake and output,use of antibiotics,length of postoperative intensive care unit stay,extubation time,new invasive operation (intra-aortic balloon counterpulsation was performed),time for use of vasoactive drugs,postoperative 24 h drainage,length of hosptial stay,serious complications (postoperative bleeding,pericardial tamponade,severe arrhythmia,heart failure,acute lung injury,renal failure and other organ function failure,etc.) and development of death.Results Compared with non-AIE group,age,body mass index and preoperative Hb,Hct,systolic blood pressure and diastolic blood pressure were significantly decreased,the rate of preoperative hypertension,neutrophil count,erythrocyte sedimentation rate,concentrations of hypersensitive c-reactive protein and amino-terminal pro-brain natriuretic peptide,body temperature and heart rate were increased,the intraoperative volume of allogeneic blood transfused and consumption of norepinephrine,phenylephrine and ephedrine after CPB were increased,the time for postoperative use of vasoactive drugs,extubation time and length of postoperative intensive care unit stay were shortened,and the length of hospital stay was prolonged in AIE group (P＜0.05).Conclusion For the patients with AIE undergoing cardiac valve surgery under CPB,comprehensive evaluation should be performed and heart failure be corrected actively before surgery;esophageal echocardiography should be used for evaluation,the application of vasoactive drugs could be increased appropriately and anesthetists should pay attention to respiratory management during surgery;cardiotonic and anti-shock therapy should be maintained,arrhythmia prevented and anti-infective therapy strengthened after surgery.
