Objective To explore the five-circuit and six-qi features of birth time and onset time of children with acute lymphoblastic leukemia(ALL).Methods A total of 877 cases of children with ALL from Children's Hospital of Soochow University from June 2021 to February 2023 were collected,and their five-circuit and six-qi features of birth time and onset time were analyzed.And then the correlation of five-circuit and six-qi features of birth time and onset time with ALL was explored preliminarily,and the pathogenic characteristics of congenital factors and acquired pathogenic factors were revealed.Results(1)The children who were born in the year with the heavenly stems being bing(the 3rd of the ten heavenly stems)and ding(the 4th of the ten heavenly stems)and with the earthly branches being shen(the 8th of the twelve earthly branches)and you(the 9th of the twelve earthly branches)are prone to suffer from ALL,and the birth year of children with ALL had the five-circuit and six-qi features of the joining of guest circuit with dominant circuit being rebellious.ALL is commonly seen in the year with the heavenly stems being geng(the 7th of the ten heavenly stems)and xin(the 8th of the ten heavenly stems)and with the earthly branches being zi(the 1st of the twelve earthly branches)and chou(the 2nd of the twelve earthly branches),and the onset year of ALL in children had the five-circuit and six-qi features of the yearly circuit being gold-circuit and water-circuit,sitian-zaiquan yearly circuit qi being shaoyin monarch-fire with yangming dryness-gold,taiyin damp-earth with taiyang cold-water,and the qi-circuit assimilation relationship being celestial correspondence,same celestial correspondence,celestial correspondence in convergent year,disharmony,mildly-rebellious,and celestial restriction.Conclusion Gold-dryness and water-cold are the congenital factors and acquired pathogenic factors of ALL.The onset of ALL in children is closely related to qi insufficiency and qi stagnation of wood and fire in five-circuit and six-qi theory.

Objective:To investigate the clinical efficacy of pancreatic cancer surgery with arterial resection.Methods:The clinicopathological and follow-up data of 135 patients undergoing pancreatectomies with arterial resection in Pancreas Center, the First Affiliated Hospital of Nanjing Medical University from Sep 2013 to Dec 2023 were retrospectively analyzed.Results:There were 77 males and 58 females, with age [ M( IQR)] of 63 (14) years old. Among the 135 patients, 122 (90.4%) were distal pancreatectomies, 8 (5.9%) were pancreaticoduodenectomies, 4 (3.0%) were total pancreatectomies and 1 (0.7%) was resection for local recurrence after distal pancreatectomy. There were 120 (88.9%) celiac axis resections, 11 (8.1%) hepatic artery resections, 1 (0.7%) superior mesenteric artery resection and 3 (2.2%) other artery resections. Simultaneous portal vein-superior mesenteric vein or organ resection accounted for 26.7% (36/135) and 29.6% (40/135),respectively. The median blood loss was 300 (300) ml and the median operation time was 275 (105) minutes. The 90-day mortality rate was 7.4% (10/135). The overall morbidity rate was 70.4% (95/135) while the major morbidity rate was 18.5% (25/135). Postoperative hemorrhage occurred in 8.9% (12/135), clinically relevant postoperative pancreatic fistula in 57.0% (77/135), bile leak in 0.74% (1/135), delayed gastric emptying in 9.6% (13/135), liver failure in 3.7% (5/135) and transient liver enzyme elevation in 44.4% (60/135). All of the 135 cases were confirmed as pancreatic cancer histologically, including 54.6% (71/130) moderately differentiated, 45.4% (59/130) poorly differentiated and no for well differentiated. The median tumor size was 4.5 (2.3) cm. The median number of harvested lymph nodes was 14 (13) and the percentage of N0, N1 and N2 according to AJCC 8th staging system was 27.1% (36/133), 52.6% (70/133) and 20.3% (27/133), respectively. The R 0 resection was achieved in 40 of 123 cases (32.5%), whose margins of specimens were assessed circumferentially based on the 1mm rule. The median overall survival time (MST) after surgery was 22.5 months, and the median progress-free survival time was 16.1 months. The overall survival rate at 1-, 2- and 5-year was 71.5%, 45.1% and 11.3%, respectively. The MST of patients who received no adjuvant therapy, chemotherapy after surgery was 8.4 months, 25.3 months, respectively. Conclusions:Pancreatectomy with arterial resection is generally safe and feasible. Survival outcome improves significantly when combined with adjuvant chemotherapy.

Objective To observe the value of multi-sequence magnetic resonance imaging(MRI)radiomics in predicting the efficacy of concurrent chemoradiotherapy(CCRT)in locally advanced cervical squamous cell carcinoma(CSCC)patients.Methods Clinical data of 100 CSCC patients underwent CCRT treatment were selected.In order to better validate the performance of the model,patients were randomly divided into the training set(70 cases)and the validation set(30 cases)in a 7∶3 ratio.According to the efficacy criteria for solid tumors,patients were divided into the complete response(CR)group(n=16)and the partial response(PR)group(n=14).Examination images of cross-sectional DWI,T2WI and enhanced T1WI were collected from all patients before treatment.ITK-SNAP software package combined with three sequences were used to outline ROI,and the open source software PyRadiomics was used to extract image omics features.For MRI omics features,the minimum redundancy maximum correlation(mRMR)algorithm was used to analyze and screen out the first 30 main features,and then the minimum absolute contraction and selection method(Lasso)based on 10-fold cross-validation was used to reduce dimensionality to screen the non-zero coefficient features.According to the weighting coefficient of Lasso-Logistic regression model in the training set,patient omics labels were calculated.Logistic regression analysis was used to construct a prediction model based on DWI,T2WI and T1WI sequence prediction models and multiple sequenomics labels.Receiver operating characteristic(ROC)curves evaluated the predictive value of each omics model for CCRT treatment in patients with locally advanced CSCC.Results There were 38 cases in the CR group and 32 cases in the PR group in the training set.There were 16 cases in the CR group and 14 cases in the PR group in the validation set.There were no significant differences in patient age,FIGO stage,differentiation degree,maximum lesion diameter and menstrual status between the CR group and the PR group in the training and validation sets.A total of 851 imaging features were extracted from the ROI target area.After the first 30 features were retained by mRMR algorithm,3 CR-related features were selected from the 851 imaging omics features of each individual sequence by Lasso algorithm and 10-fold cross-validation.Eight CR related features were selected from 2 553 features after the combination of the three sequences.ROC curve results showed that in the training set and validation set,the AUC of multiple sequences combined to predict the therapeutic effect of CCRT in patients with locally advanced CSCC was 0.971 and 0.946,respectively,which was higher than that of T1WI,T2WI and DWI single sequence prediction(training set Z=2.683,2.046,2.817,P＜0.05;verification set Z=2.075,2.117,2.005,P＜0.05).Conclusion The multi sequence MRI radiomics model has high predictive value for the efficacy of CCRT treatment in locally advanced CSCC patients.

Objective:To assess the feasibility of wavelet index (WLI) in monitoring the depth of sedation with propofol in pediatric patients.Methods:This was a prospective observational trial. One hundred and sixty-five pediatric patients, aged >1-12 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, undergoing elective surgery requiring general anesthesia with endotracheal intubation or laryngeal mask airway from July to December 2016 in our hospital, were divided into 11 age groups ( n=15 each): >1-2 yr group, >2-3 yr group, >3-4 yr group, >4-5 yr group, >5-6 yr group, >6-7 yr group, >7-8 yr group, >8-9 yr group, >9-10 yr group, >10-11 yr group, and >11-12 yr group. General anesthesia was induced by injection of propofol 3 mg/kg for more than 30 s. WLI and BIS values were recorded immediately before administration and at 30, 40, 50, 60, 90, 120, 180 and 240 s after the end of administration. If there were differences among age groups, age groups with no statistically significant differences were combined and re-grouped. Pearson linear correlation analysis and Bland-Altman consistency analysis were performed. Results:A total of 149 pediatric patients were actually included. There were no significant differences in BIS values between 4 groups aged > 1-5 yr and between 7 groups aged > 5-12 yr ( P>0.05). Regrouping was performed based on the aforementioned results, 4 groups of children aged > 1-5 yr were divided into > 1-5 yr group ( n=60), and 7 groups of children aged > 5-12 yr were divided into > 5-12 yr group ( n=89). WLI values and BIS values were significantly decreased at each time point after administration compared with immediately before administration in group aged > 1-5 yr and in group aged >5-12 yr ( P<0.05). The BIS values were the lowest at 60 s after the end of the administration, and the WLI values were the lowest at 120 and 180 s after the end of the administration in two groups ( P<0.05). There were no statistically significant differences between WLI values and BIS values at 90 s and 240 s after the end of the administration ( P>0.05), and there was statistically significant difference at the other time points in group aged > 1-5 yr ( P<0.05). There was no significant difference between WLI values and BIS values at 180 s and 240 s after the end of the administration ( P>0.05), but there were significant differences at the other time points in group aged > 5-12 yr ( P<0.05). The Pearson correlation coefficients between WLI values and BIS values were 0.61 and 0.56 in group aged > 1-5 yr and group aged > 5-12 yr, respectively ( P<0.001). Bland-Altman agreement analysis: In group aged > 1-5 yr and group aged > 5-12 yr, the 95% agreement limits were -0.484-0.621 and -0.551-1.015, respectively, and there were 4.6% (23/504) and 5.1% (40/777) of the points outside the 95% agreement limits, respectively, and both limits exceeded the clinically acceptable range. Conclusions:WLI is feasible for monitoring the depth of sedation with propofol in pediatric patients aged > 1-12 yr, but the accuracy is lower than BIS.

Objective:To explore the impact of sleep disorders on the therapeutic effects of different inhaled medications in patients with chronic obstructive pulmonary disease (COPD).Methods:A prospective observational study was conducted on 393 patients with stable COPD who visited the Department of Respiratory and Critical Care Medicine, the Second Xiangya Hospital, Central South University from December 2020 to September 2021. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep quality of patients with chronic obstructive pulmonary disease, and patients were divided into a non sleep disorder group and a sleep disorder group. The Berlin questionnaire was used to assess the risk of obstructive sleep apnea syndrome (OSAS) in patients, and the hospital anxiety and depression questionnaire (HADS) was used to assess the presence of anxiety and depression in patients. The improvement of symptoms [minimum clinically significant difference (MCID)] and the deterioration of symptoms [clinical significant symptom deterioration (CID)] within six months of patient follow-up were evaluated. The moderate to severe acute exacerbation of the patient was recorded during the one-year follow-up period. The clinical characteristics of two groups of patients were compared, and multiple regression analysis was used to evaluate the relationship between sleep quality and the prognosis of chronic obstructive pulmonary disease, as well as the impact of sleep disorders on the treatment efficacy of different inhaled drugs.Results:The average age of 393 patients with chronic obstructive pulmonary disease was (62.9±8.3)years old, with a median percentage of forced expiratory volume in the first second (FEV 1%) of 53.7%(30.7%) and a mean PSQI score of (5.7±3.4)points. 186 cases (47.3%) of patients had sleep disorders. Compared with patients in the non sleep disorder group, patients in the sleep disorder group had a higher proportion of middle school education and below, lower FEV 1 and FEV 1/forced vital capacity (FVC), higher baseline COPD Assessment Test (CAT), modified Medical Research Council (mMRC) and Clinical COPD Questionnaire (CCQ) scores, and a higher proportion of comorbid anxiety (all P<0.05). Compared with patients without sleep disorders, patients with sleep disorders had a lower incidence of MCID ( P=0.030) and a higher incidence of CID ( P=0.005). During the one-year follow-up period, patients with sleep disorders experienced a higher proportion of moderate to severe acute exacerbation ( P=0.001), severe acute exacerbation ( P=0.003), and frequent acute exacerbation ( P=0.009). The results of multiple regression analysis showed that patients with sleep disorders had a lower likelihood of developing MCID ( OR: 0.288, 95% CI: 0.145-0.379, P<0.001), and an increased risk of developing CID ( OR: 3.150, 95% CI: 2.011-4.388, P<0.001) and acute exacerbation ( OR: 1.659, 95% CI: 1.162-2.368, P=0.005). Compared with patients using long-acting muscarinic antagonist (LAMA) or inhaled corticosteroids (ICS)+ long-acting β2-agonist (LABA), patients in the sleep disorder group who used LABA+ LABA were more likely to develop MCID ( OR: 1.420, 95% CI: 1.021-2.751, P=0.010; OR: 1.976, 95% CI: 1.123-2.227, P=0.023). Conclusions:Compared with patients without sleep disorders, COPD patients with sleep disorders have a lower likelihood of symptom improvement, and a higher risk of symptom deterioration and acute exacerbation.Patients with COPD with sleep disorders are more likely to achieve symptom improvement by using LABA+ LAMA.

Purpose To investigate the diagnostic value of multimodal imaging in cardiac lipoma.Materials and Methods The clinical symptoms,echocardiography,CT and cardiac magnetic resonance images of 14 patients with cardiac lipoma diagnosed in Xijing Hospital of Air Force Military Medical University from July 2016 to November 2022 were retrospectively analyzed.Results Five patients with lipoma had symptoms of chest tightness and shortness of breath.A total of 18 lesions were found in 14 cases with cardiac lipoma.The locations of cardiac lipomas were widely distributed in the heart,of which 9 were located under the inner lining of the ventricular lumen(6 in the left ventricle,3 in the right ventricle),5 in the myocardium(4 in the left ventricle wall,1 in the right ventricle wall),3 in the pericardium,and 1 in the right ventricle.Echocardiography of 12 cases showed strong echoic mass image,and CT of 7 cases showed uniform low-density mass image.All patients cardiac magnetic resonance showed high signal of T1WI,and the tumor signal of lipid-pressure sequence decreased significantly.T2WI showed high signal and low signal ring around the tumor,indicating a chemical shift artifact.In the film sequence of heart,the mass could be seen to wobble gently and change in the shape of spontaneous motion cycle.The first perfusion scan did not show perfusion elevation.No enhancement was observed on the delayed enhanced scan.Native T1 mapping showed that the T1 value of mass was significantly lower than that of normal myocarda[(255.9±48.4)ms vs.(994.2±66.4)ms],and the difference was statistically significant(t=-32.5,P<0.001).Conclusion Multimodal imaging can provide objective evidence for clinical diagnosis of cardiac lipoma.Lipomas with extremely low T1 values were found,which is helpful to assist in the diagnosis of cardiac lipoma,clearer observation of the lesions,accurate localization,and strong ability to detect small lesions.Therefore,when cardiac lipoma is suspected,T1 mapping can be used as a routine examination method for the diagnosis and differential diagnosis of cardiac masses.

Background::Acute respiratory distress syndrome (ARDS) is a common cause of respiratory failure in many critically ill patients. Although inflammasome activation plays an important role in the induction of acute lung injury (ALI) and ARDS, the regulatory mechanism of this process is still unclear. When cells are stimulated by inflammation, the integrity and physiological function of mitochondria play a crucial part in pyroptosis. However, the underlying mechanisms and function of mitochondrial proteins in the process of pyroptosis are largely not yet known. Here, we identified the 18-kDa translocator protein (TSPO), a mitochondrial outer membrane protein, as an important mediator regulating nucleotide-binding domain, leucine-rich repeat, and pyrin domain-containing protein 3 (NLRP3) inflammasome activation in macrophages during ALI.Methods::TSPO gene knockout (KO) and lipopolysaccharide (LPS)-induced ALI/ARDS mouse models were employed to investigate the biological role of TSPO in the pathogenesis of ARDS. Murine macrophages were used to further characterize the effect of TSPO on the NLRP3 inflammasome pathway. Activation of NLRP3 inflammasome was preformed through LPS + adenosine triphosphate (ATP) co-stimulation, followed by detection of mitochondrial membrane potential, reactive oxygen species (ROS) production, and cell death to evaluate the potential biological function of TSPO. Comparisons between two groups were performed with a two-sided unpaired t-test. Results::TSPO-KO mice exhibited more severe pulmonary inflammation in response to LPS-induced ALI. TSPO deficiency resulted in enhanced activation of the NLRP3 inflammasome pathway, promoting more proinflammatory cytokine production of macrophages in LPS-injured lung tissue, including interleukin (IL)-1β, IL-18, and macrophage inflammatory protein (MIP)-2. Mitochondria in TSPO-KO macrophages tended to depolarize in response to cellular stress. The increased production of mitochondrial damage-associated molecular pattern led to enhanced mitochondrial membrane depolarization and pyroptosis in TSPO-KO cells. Conclusion::TSPO may be the key regulator of cellular pyroptosis, and it plays a vital protective role in ARDS occurrence and development.

Objective To explore the clinical effect and safety of remimazolam combined with alfentanil in painless gastroenteroscopy in elderly patients.Methods 188 elderly patients who were scheduled to undergo painless gastroenteroscopy from October 2021 to February 2023 were selected and divided into group A,group B,group C,and group D by random number table method,with 47 cases in each group.The group A,group B and group C were used remimazolam 0.2,0.3 and 0.4 mg/kg,and alfentanil 3 μg/kg respectively,and the remimazolam 2.5 mg/time was added during the operation.The group D was used propofol 1.5 mg/kg and alfentanil 3 μg/kg,and a single dose of propofol 0.5 mg/kg was added during the operation.The hemodynamics at different time points[3 min before anesthesia administration(T0),immediately after endoscopy(T1),3 min after endoscopy(T2),at the end of examination(T3),at the time of awakening(T4)],anesthesia onset time,sedation success rate,gastrointestinal endoscopy time,awakening time,time to leave the observation room and intraoperative/postoperative complications were compared,and the test results of neurobehavioral cognitive state examination(NCSE)were compared at different times.Results The percutaneous arterial oxygen saturation(SpO2)at T1 and T2 time point were higher than group C and group D,and the differences were statistically significant(P<0.05).There was no statistically significant difference in the heart rate(HR)and mean arterial pressure(MAP)among group A,group B,group C and group D at each time point(P>0.05).There was no statistically significant difference in SpO2 between group A and group B at each time point(P>0.05).There was no statistically significant difference in the success rate of sedation,gastrointestinal endoscopy examination time and time of leaving the observation room among the four groups(P>0.05),but the onset time of anesthesia in group A was longer than that in group B,group C and group D,and the awakening time in group A and group B was shorter than that in group C and group D,and the differences were statistically significant(P<0.05).There was no statistically significant difference in awakening time between group A and group B(P>0.05).The incidence rate of bradycardia in group A and group B was lower than in group D,and the incidence rates of hypoxemia,respiratory depression,hypotension,and dizziness in group A were lower than those in group D,and the incidence rate of injection pain in group A,group B and group C was lower than that in group D,and the differences were statistically significant(P<0.05).After 10 minutes of complete wakefulness,there was no statistically significant difference in the passing rates of calculation ability and the memory tests between group A and group B(P>0.05),but the passing rates of calculation ability and memory test in group A were higher than those in group C and group D,and the differences were statistically significant(P<0.05).Conclusion During painless gastroenteroscopy in elderly patients,the sedative effect of using 0.3 mg/kg remimazolam combined with alfentanil is good,and it has stable hemodynamics,and the occurrence rate of complications such as bradycardia and espiratory depression is low,and the early postoperative cognitive function is recovered well.
