Objective:To evaluate the feasibility of utilizing artificial intelligence (AI) to assist junior anesthesia residents in making the preoperative anesthesia plans.Methods:Forty anesthesia residents in their third year of training, who had obtained their practicing physician qualifications in the Yangzhou area, were assigned into 4 groups ( n=10 each) using a random number table method: Chat-GPT combined with Bing chat group (C-G-B group), Chat-GPT group (C-G group), Bing chat group (B group), and control group (C group). Fifty patients undergoing elective non-cardiac surgery were selected from the anesthesia clinic as teaching cases. C-G-B, C-G and B groups utilized different AI tools to assist trainees in designing anesthesia plans, producing standardized textual outputs. Each trainee underwent a baseline knowledge test through a professional theory examination prior to enrollment. The completeness and accuracy of the preoperative anesthesia plans were evaluated and scored by 3 chief anesthesiologists. The total time spent on plan formulation and satisfaction scores regarding AI tool feedback were recorded. An analysis was conducted based on the American Society of Anesthesiologists (ASA) Physical Status classification of teaching cases. Results:In ASA Physical Status classification Ⅰ and Ⅱ teaching cases, there was no statistically significant difference in completeness and accuracy scores among the four groups ( P>0.05). In ASA Physical Status classification Ⅲ teaching cases, compared to C group, the completeness and accuracy scores were significantly increased in C-G-B, C-G and B groups, with the highest scores observed in C-G-B group ( P<0.05). Among all teaching cases (ASA Physical Status classification Ⅰ-Ⅲ), the total time spent was significantly shortened in C-G and B groups as compared to C and C-G-B groups ( P<0.05). There was no statistically significant difference in the total time spent between C-G group and C-G-B group ( P>0.05). Compared to C-G and B groups, the satisfaction score was significantly decreased in C-G-B group ( P<0.05). Conclusions:For ASA Physical Status classification Ⅲ patients, using AI to assist junior anesthesia residents in making preoperative anesthesia plans may offer advantages. Although combining the use of Chat-GPT and Bing chat can further improve the completeness and accuracy of anesthesia plan development, it may require more time.

Objective:To evaluate the effect of controlled low central venous pressure (CLCVP) induced by milrinone on intraoperative cerebral blood flow in the patients undergoing laparoscopic hepatectomy.Methods:Eighty American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients, regardless of gender, scheduled for elective laparoscopic hepatectomy, with body mass index of 18-30 kg/m 2, aged 18-64 yr, were divided into 2 groups ( n=40 each) by a random number table method: nitroglycerin group (X group) and milrinone group (M group). After the start of surgery, milrinone 0.5 μg·kg -1·min -1 was continuously infused in group M and nitroglycerin 0.5-1.5 μg·kg -1·min -1 was continuously infused in group X to maintain central venous pressure (CVP)<5 cmH 2O. Norepinephrine 0.01-0.10 μg·kg -1·min -1 was intravenously injected during operation to maintain mean arterial pressure at 60-90 mmHg. Norepinephrine 8-16 μg was intravenously injected when necessary. At 10 min after tracheal intubation (T 1), after establishment of pneumoperitoneum (T 2), at 5 and 30 min after CVP reached the target value (T 3, T 4), at 5 min after CVP returned to normal value (T 5) and at the end of surgery (T 6), the internal carotid artery mean blood flow velocity, internal carotid artery blood flow, cardiac output, and cardiac index were recorded. The surgical field score, consumption of intraoperative norepinephrine, fluid input and output, and occurrence of adverse reactions at 7 days after operation were recorded. Results:Compared with group X, the cardiac output, cardiac index, internal carotid artery mean blood flow velocity and internal carotid artery blood flow were significantly increased, the consumption of intraoperative norepinephrine was decreased, and the surgical field score was increased at T 3-5 in group M ( P<0.05). There was no significant difference in the intraoperative fluid intake and output and incidence of postoperative adverse reactions at each time point between the 2 groups ( P>0.05). Conclusions:Compared with nitroglycerin-induced CLCVP, milrinone-induced CLCVP can improve the reduction in intraoperative cerebral blood flow in the patients undergoing laparoscopic hepatectomy to some extent.

Objective To systematically evaluate the efficacy and safety of plum-blossom needle therapy for vitiligo by using the systematic review and meta analysis.Methods The randomized controlled trials(RCT)on plum-blossom needle for treating vitiligo were systematically retrieved from the databases of the PubMed,China Biological Medicine Database,CNKI,Wanfang Data and VIP database from the database estab-lishment to June 2,2022.The literatures were screened according to the inclusion and exclusion criteria.The finally included literatures conducted the data extraction.The RevMan 5.4 software was used for conducting the data analysis.The methodological quality evaluation on the included trials was performed by the ROB tool.The GRADE method was used to assess the evidence level.Results A total of 7 trials involving 469 pa-tients were finally included.The meta analysis results showed that the plum-blossom needle combined with other therapies(including laser or ultraviolet irradiation,tacrolimus ointment,compound Kaliziran tincture)was superior to the other therapies alone in the aspects of improving vitiligo skin lesion including reducing the of white spot skin lesion area(MD=-1.11,95％CI:-1.92 to-0.30,P=0.007),increasing the repigment-ation rate of vitiliginous lesions(MD=18.09,95％CI:1.55 to 34.63,P=0.030)and enhancing the pigment deposition in vitiligo lesions(MD=0.92,95％CI:0.32 to 1.52,P=0.003),and improving the patients'quali-ty of life(MD=-7.48,95％CI:-8.04 to-6.92,P＜0.001),and the differences were statistically signifi-cant.In terms of safety,there was no statistically significant difference in adverse events between plum blos-som acupuncture combined with other therapies and other therapies alone(RR=1.20,95％CI:0.77 to 1.84,P=0.420).Conclusion Low or very low evidence shows that plum-blossom needle combined with other therapies for treating vitiligo may enhance the effect in the aspects of improving the white spot skin lesions and quality of life in the patients with vitiligo,moreover which is relatively safe.

Objective:To evaluate the effect of individualized positive end-expiratory pressure (PEEP) titration based on open-lung strategy on the intraoperative thoracic fluid content (TFC) in elderly patients undergoing transurethral ultrasound-guided laser-induced prostatectomy (TULIP).Methods:Eighty-six American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, patients, aged 65-80 yr, with body mass index of 18-28 kg/m 2, scheduled for elective TULIP, were divided into 2 groups ( n=43 each) by the random number table method: fixed PEEP group (group C) and individualized PEEP titration group (group P). PEEP was set at 4 cmH 2O after routine mechanical ventilation in group C. Patients underwent pulmonary recruitment maneuvers combined with individualized PEEP titration during surgery in group P. TFC was measured using a non-invasive cardiac output monitor at 5 min after tracheal intubation (T 0), 30 min after PEEP titration and ventilation (T 1), 5 min before surgery (T 2), and 5 min before leaving the recovery room (T 3). Cardiac output, oxygenation index and stroke volume index were recorded from T 0-T 2, arterial blood gas analysis was simultaneously performed to record peak airway pressure and dynamic lung compliance, and oxygenation index was calculated. The duration of postanesthesia care unit stay, pulmonary complications within 7 days after surgery, and length of hospital stay were also recorded. Results:Eighty-three patients were finally included, with 42 in group C and 41 in group P. Compared with group C, TFC was significantly decreased at T 1-T 3, cardiac index, cardiac output and stroke volume index were decreased at T 1, dynamic lung compliance, PaO 2 and oxygenation index were increased at T 1 and T 2, PaCO 2 was decreased, the incidence of postoperative pulmonary complications was reduced, and the duration of postanesthesia care unit stay and postoperative length of hospital stay were shortened in group P ( P<0.05). Conclusions:Individualized PEEP titration based on open-lung strategy can effectively decrease TFC and improve intraoperative oxygenation and prognosis in elderly patients undergoing TULIP.

Objective:To understand the current status of anemia, iron deficiency, and iron-deficiency anemia among preschool children in China.Methods:A cross-sectional study was conducted with a multi-stage stratified sampling method to select 150 streets or townships from 10 Chinese provinces, autonomous regions, or municipalities (East: Jiangsu, Zhejiang, Shandong, and Hainan; Central: Henan; West: Chongqing, Shaanxi, Guizhou, and Xinjiang; Northeast: Liaoning). From May 2022 to April 2023, a total of 21 470 children, including community-based children aged 0.5 to<3.0 years receiving child health care and kindergarten-based children aged 3.0 to<7.0 years, were surveyed. They were divided into 3 age groups: infants (0.5 to<1.0 year), toddlers (1.0 to<3.0 years), and preschoolers (3.0 to<7.0 years). Basic information such as sex and date of birth of the children was collected, and peripheral blood samples were obtained for routine blood tests and serum ferritin measurement. The prevalence rates of anemia, iron deficiency, and iron-deficiency anemia were analyzed, and the prevalence rate differences were compared among different ages, sex, urban and rural areas, and regions using the chi-square test.Results:A total of 21 460 valid responses were collected, including 10 780 boys (50.2%). The number of infants, toddlers, and preschoolers were 2 645 (12.3%), 6 244 (29.1%), and 12 571 (58.6%), respectively. The hemoglobin level was (126.7±14.8) g/L, and the serum ferritin level was 32.3 (18.5, 50.1) μg/L. The overall rates of anemia, iron deficiency, and iron-deficiency anemia were 10.4% (2 230/21 460), 28.3% (6 070/21 460), and 3.9% (845/21 460), respectively. The prevalence rate of anemia was higher for boys than for girls (10.9% (1 173/10 780) vs. 9.9% (1 057/10 680), χ2=5.58, P=0.018), with statistically significant differences in the rates for infants, toddlers and preschoolers (18.0% (475/2 645), 10.6% (662/6 244), and 8.7% (1 093/12 571), respectively, χ2=201.81, P<0.01), and the rate was significantly higher for children in rural than that in urban area (11.8% (1 516/12 883) vs. 8.3% (714/8 577), χ2=65.54, P<0.01), with statistically significant differences in the rates by region ( χ2=126.60, P<0.01), with the highest rate of 15.8% (343/2 173) for children in Central region, and the lowest rate of 5.3% (108/2 053) in Northeastern region. The prevalence rates of iron deficiency were 33.8% (895/2 645), 32.2% (2 011/6 244), and 25.2% (3 164/12 571) in infants, toddlers, and preschoolers, respectively, and 30.0% (3 229/10 780) in boys vs. 26.6% (2 841/10 680) in girls, 21.7% (1 913/8 821), 40.0% (870/2 173), 27.1% (2 283/8 413), 48.9% (1 004/2 053) in Eastern, Central, Western, and Northeastern regions, respectively, and each between-group showed a significant statistical difference ( χ2=147.71, 29.73, 773.02, all P<0.01). The prevalence rate of iron-deficiency anemia showed a significant statistical difference between urban and rural areas, 2.9% (251/8 577) vs. 4.6% (594/12 883) ( χ2=38.62, P<0.01), while the difference in iron deficiency prevalence was not significant ( χ2=0.51, P=0.476). Conclusions:There has been a notable improvement in iron deficiency and iron-deficiency anemia among preschool children in China, but the situation remains concerning. Particular attention should be paid to the prevention and control of iron deficiency and iron-deficiency anemia, especially among infants and children in the Central, Western, and Northeastern regions of China.

OBJECTIVE To investigate whether icari-in(ICA)plays a neuroprotective role by improving glyco-lytic function through activating Wnt/β-catenin signaling pathway.METHODS HT22 cells were treated with Aβ25-35 for 24 h to establish AD cell model,ICA was added in 2 h before Aβ25-35 and the DKK1(a specific inhibitor of the Wnt signaling pathway)was added in 0.5 h before ICA.Pharmacodynamic study:HT22 cells were divided into control group,ICA group(ICA 10 μmol·L-1),model group(Aβ25-3520 μmol·L-1),model + ICA group(Aβ25-3520 μmol·L-1 +ICA 2.5,5,10 μmol·L-1);Mechanism study:HT22 cells were divided into control group,model group,Aβ25-35+ICA 10 μmol·L-1 group,Aβ25-35+DKK1 group,Aβ25-35+DKK1+ ICA group.The cell viability was detected by MTT assay and the cell morphology was obtained by microscope,the lactate content was detected by lactate assay,the ATP content was measured with the chemiluminescence method,the expression levels of HK1,PKM1 and the pro-tein expression of molecules related to the Wnt/β-catenin signaling pathway(Wnt3a,GSK3β,pGSK3β Try216,pGSK3β Ser9,β-catenin,pβ-catenin Ser33/37 Thr41,Active β-catenin and nuclear β-catenin)was assayed by Western blotting.The nuclear translocation of β-catenin was observed by immunofluorescent staining.RESULTS Compared with the control group,the viability of cells in the model group was reduced,the morphology of cells was significantly damaged,the ATP content and lactate content were significantly decreased,and the glycolytic key enzymes:the protein levels of HK1,PKM1 and the protein levels of Wnt3a,pGSK3β Ser9,active β-catenin and nuclear β-catenin were significantly reduced,and the phosphorylation levels of β-catenin Ser33/37 Thr41 were significantly increased.Compared with the model group,the cell morphology was significantly improved and the viability was significantly increased,the ATP and lactate content were significantly increased,the expressions of HK1,PKM1 and Wnt3a,pGSK3β Ser9,active β-catenin and nuclear β-catenin protein were significantly upregulat-ed,and the phosphorylation levels of β-catenin Ser33/37 Thr41 were significantly reduced after ICA treatment.However,when the canonical Wnt signaling was inhibited by DKK1,the above effects of ICA on glycolysis were abolished.CONCLUSION ICA exerts neuroprotective effects on Aβ25-35-induced HT22 cell injury by enhancing the glycolysis function through the activation of the Wnt/β-catenin signaling pathway.

Bronchial asthma and anaphylaxis are two conditions related to the sensitization state of the body that can coexist with each other in children.Asthma is a common chronic respiratory disease in children, while anaphylaxis is a rapid onset emergency involving multiple systems of the body.The two diseases can affect each other.Poor asthma control can increase the risk of anaphylaxis, and there is a risk of misdiagnosis during symptom onset.Both diseases need prompt and appropriate acute treatment as well as long term management.This review summarizes the various associations and differences between asthma and anaphylaxis, as well as management tools and strategies, in order to provide reference for enhancing disease awareness and optimizing disease management.
