This article systematically analyzed the historical evolution of the origin， scientific name， producing area， quality evaluation， harvesting and processing， and other aspects of Quisqualis Fructus by consulting the ancient materia medica， medical books， prescription books， local literature and combining with the modern literature and standards， summarized and explored the development rules of its medicinal properties and efficacy along with their underlying causes， in order to provide support for the development and utilization of famous classical formulas containing this herb. According to the textual research， Shijunzi was first recorded as Liuqiuzi in Nanfang Caomuzhuang of the Jin dynasty， and the name of Shijunzi was first used in Kaibao Bencao of the Song dynasty， which has been consistently used throughout subsequent dynasties， and there were also aliases such as Junziren， Sijunzi， and Dujilizi. The mainstream source of Quisqualis Fructus used in the past dynasties has been the dried mature fruits of Quisqualis indica， a plant belonging to the family Combretaceae. In modern times， its variety Q. indica var. villosa has also been recorded as the medicinal material of Quisqualis Fructus. In 2007， the Flora of China（English edition） designated Q. indica var. villosa as a synonym of Q. indica. Today， the accepted name of Shijunzi is updated to Combretum indicum. According to ancient herbal records， the producing areas of Quisqualis Fructus were Guangdong， Hong Kong， Macao， Guangxi， Hainan， Sichuan and Fujian， and then gradually expanded to Yunnan， Taiwan， Jiangxi and Guizhou. Since the Song dynasty， two major production regions have gradually emerged in Sichuan， Chongqing and Fujian. Currently， it is primarily cultivated in Chongqing， Guangxi and other areas， with Chongqing yielding the highest output. Since modern times， superior quality has been defined by large size， a purple-black surface， plump grains， and a yellowish-white kernel. According to ancient herbal records， the harvesting period of Quisqualis Fructus was the July and August of the lunar calendar， mostly used raw after shelling or with the shell intact， it underwent processing methods such as cleaning， slicing， mixing， steaming， roasting， stewing， and frying. Currently， the harvesting period is autumn， followed by sun-drying or low-heat drying， with processing methods including cleaning， stir-frying， and stewing. In ancient and modern literature， the records of the properties， functions and indications of Quisqualis Fructus are basically the same， that is， sweet in taste， warm in nature， predominantly non-toxic， belonging to the spleen and stomach meridians. It possesses effects of insecticide， decontamination and invigorating spleen for ascariasis， enterobiasis， abdominal pain due to worm accumulation and infantile malnutrition.The contraindications for use primarily include avoiding consumption by individuals without parasitic infestations， limiting use for those with spleen-stomach deficiency-cold， refraining from drinking hot tea during medication， and avoiding excessive intake. Based on the textual research， it is suggested that the dried mature fruits of Q. indica should be used as the medicinal material for the development of famous classical formulas containing Quisqualis Fructus. Processing methods may be chosen according to prescription requirements， and the raw products is recommended for medicinal use if not specified.

Objective To investigate the effect of transcutaneous electrical acupoint stimulation(TEAS)on emergence agitation(EA)in children undergoing selective posterior rhizotomy(SPR).Methods Forty-two children with cerebral palsy undergoing SPR were selected,20 males and 22 females,aged 6-12 years,BMI 13-24 kg/m2,ASA physical status Ⅰ or Ⅱ,randomly divided into two groups:TEAS group(group T)and control group(group C),21 children in each group.Children in group T re-ceived TEAS at the bilateral acupoints of Neiguan and Hegu from 30 minutes before anesthesia induction to the end of surgery.In group C,electrodes were placed on the same acupoints without electrical stimulation.All children in both groups received total intravenous anesthesia.HR and MAP were recorded at the time of entry,extubation,5,15,30 minutes after extubation.The consumption of remifentanil and propofol during the procedure were recorded.The time of operation and extubation were recorded.The Wong-Baker faces pain scale-revised(FPS-R)and the pediatric anesthesia emergence delirium(PAED)were recorded at 15 minutes after extubation,and the incidence of EA was assessed by PAED.While,the occurrence of post-operative nausea and vomiting(PONV)was recorded.Results Compared with that at the time of entry,HR at the time of extubation,5,15 minutes after extubation and MAP at the time of extubation,5,15,30 minutes after extubation in group C were significantly increased(P＜0.05),HR and MAP at the time of extubation,5,15 minutes after extubationin group T were significantly increased(P＜0.05).Compared with group C,HR was significantly slower and MAP was significantly lower in group T at the time of extuba-tion,5,15,30 minutes after extubation(P＜0.05).Compared with group C,the consumption of remifen-tanil during operation was reduced,the time of extubation was significantly shortened,the FPS-R and PAED were significantly decreased,and the incidence of EA were significantly reduced(P＜0.05).There were no significant differences in the time of operation,the consumption of propofol during operation and the inci-dence of PONV.Conclusion TEAS is beneficial to prevent the occurrence of EA in pediatric patients un-dergoing SPR,stabilize hemodynamics,reduce the dosage of opioids during surgery,reduce the postopera-tive pain,andaccelerate the time of anesthesia resuscitation.

Objective:To evaluate the effect of regional oxygen saturation (rSO 2)-guided low-dose norepinephrine on postoperative cognitive dysfunction (POCD) in elderly patients undergoing hip replacement under general anesthesia. Methods:One hundred and twenty patients of both sexes, aged 65-80 yr, with body mass index of 18-24 kg/m 2, of American Society of Anesthesiologists physical statusⅠ-Ⅲ, scheduled for hip replacement under general anesthesia, were divided into 2 groups ( n=60 each) using a random number table method: control group (group C) and low-dose norepinephrine guided by rSO 2 group (group RN). The patients in both groups received superior inguinal fascial space block combined with general anesthesia under laryngeal mask placement.In group C, the fluctuation range of mean arterial pressure (MAP) was not more than 20% of the baseline, vasoactive agents were administered according to the changes in blood pressure, rSO 2 was monitored continuously, but the change rate of rSO 2 was not used as the regulating index.In group RN, norepinephrine was infused continuously via the central vein at 0.01-0.10 μg·kg -1·min -1 after anesthesia induction, the dose was adjusted according to rSO 2, the rSO 2 change rate was maintained≤10%, the fluctuation range of mean arterial pressure was not more than 20% of the baseline, and vasoactive agents were administered when necessary.MAP, end-tidal pressure of carbon dioxide (P ETCO 2) and rSO 2 were recorded after inhalation of oxygen (T 0), at 5 min after anesthesia induction (T 1), at 30 min after skin incision (T 2), at the end of surgery (T 3) and after recovery and extubation (T 4), and the change rate of rSO 2 was calculated.The occurrence of adverse events and amount of vasoactive drugs used were recorded.The cognitive function was assessed using Montreal Scale at 1 day before surgery and 7 days after surgery, and the development of postoperative cognitive dysfunction (POCD) was calculated using Z score.The postoperative hospital stay time was recorded. Results:Compared with group C, MAP and rSO 2 were significantly increased, and the change rate of rSO 2 was decreased at T 1, 2 in group RN ( P<0.05). Compared with group C, the requirement for intraoperative vasoactive drugs was significantly decreased, the consumption of norepinephrine was increased, MoCA total score, attention and delayed recall sub-score were increased at 7 days after surgery, the incidence of POCD was decreased, and the postoperative hospital stay time was shortened in group RN ( P<0.05). Conclusion:Low-dose norepinephrine guided by rSO 2 can decrease the development of POCD in elderly patients undergoing hip replacement under general anesthesia.

[Absrtact] Objective To investigate the effect of anatomic quantitative target evaluation of class-room teaching on students' professional knowledge learning ability. Methods Twenty-five international students of 6-year program of grade 2013 were chosen as the experimental group, while twenty-seven Chinese students coming from the same class of grade 2013 and fifteen international students of 6-year program of grade 2012 were chosen as two control groups; quantitative and non-quantitative evaluation were imple-mented respectively by classroom questions and answers; teaching effects were evaluated by scales in the separation of teaching and examination, by records of answers for in-class questions and by questionnaire survey; SPSS 20.0 was used to make statistical analysis, one-way ANOVA and Kruskal Wallis test to com-pare the scores of three groups of students, P<0.05 indicates statistic significance. Results Compared with control groups, the accuracy of answers for class questions were improved greatly in the experimental group (2/3~3/4) vs. (1/2) and (2/3~3/4) vs. (1/2) and the average test scores (80.62±5.93) vs. (79.62±5.93) and (80.62 ±5.93) vs. (70.16 ±6.36) of the experimental group students were higher than control groups, the difference was statistically significant between the control group and the control group (P=0.045). Conclusions
Quantitative evaluation of teaching objectives in anatomy class can improve the learning attitude of foreign students and enhance their academic ability.

Objective: To explore influence of exercise on cardiac autonomic nerve function in patients undergoing coronary artery bypass grafting (CABG) and its clinical significance. Methods: A total of 53 patients with coronary heart disease undergoing CABG were randomly divided into routine treatment group (n=25) and rehabilitation group (n=28, received exercise training based on routine treatment). Changes of autonomic nerve function before, second and eighth week after CABG were analyzed in two groups using time domain indexes of heart rate variability (HRV) by ambulatory electrocardiography, including standard deviation of normal to normal RR intervals calculated over the 24 h period (SDNN), standard deviation of normal to normal RR intervals in all 5 min segments of the entire recording (SDANN), root-mean square of differences between successive normal to normal intervals (rMSSD) and adjacent normal RR interval difference > 50ms stroke accounted for a percentage of 24h total RR interval (PNN50). Results: Compared with before CABG, there were significant decrease in SDNN, SDANN, RMSSD and PNN50 in both groups two weeks after CABG (P<0.05~0.01); eight weeks after CABG, above indexes recovered to levels before CABG in routine treatment group[SDNN （113.6±29.4）vs.（116.7±24.7）, SDANN（112.2±32.1）vs.（113.6±28.6）, rMSSD（21.9±8.2） vs.（23.2±7.1）, and PNN50 （7.5±4.2）vs.（8.2±3.7）] , P>0.05 all; Compared with before CABG, there were significant improvements in SDNN [(114.7±25.2) ms vs. (132.6±30.6) ms], SDANN [(111.6±23.5) ms vs. (129.2±30.8) ms], rMSSD [(24.2±8.7) ms vs. (29.9±7.5) ms] and PNN50 [(7.8±2.2) ms vs. (9.5±2.3) ms], and there were significant improvement than those of routine treatment group [SDNN （132.6±30.6）vs.（113.6±29.4）, SDANN（129.2±30.8）vs.（112.2±32.1）, rMSSD（29.9±7.5）vs.（21.9±8.2）and PNN50 （9.5±2.3）vs.（7.5±4.2）] eight weeks after CABG in rehabilitation group, P<0.05 all. Conclusion: All HRV indexes significantly decrease on two weeks after CABG in both groups, suggesting that CABG can damage cardiac autonomic nerve system. These indexes of rehabilitation group were more improvement than those of routine treatment group, suggesting exercise training can more significantly improve cardiac autonomic nerve function after CABG.
