BACKGROUND:Allogeneic hematopoietic stem cell transplantation is an effective and even the only way to cure various hematological diseases,but the short-term mortality rate is relatively high after transplantation. OBJECTIVE:To investigate the risk factors affecting the overall survival of patients with hematological diseases in the short term(within 100 days)after allogeneic hematopoietic stem cell transplantation,so as to reduce mortality and effectively prevent related risks in the short term(within 100 days)after allogeneic hematopoietic stem cell transplantation. METHODS:Clinical data of 585 patients with hematological diseases who underwent allogeneic hematopoietic stem cell transplantation at the Hematopoietic Stem Cell Transplantation Center of First Affiliated Hospital of Zhengzhou University from January 1,2018 to June 30,2021 were retrospectively analyzed.The risk factors that affected overall survival within 100 days after allogeneic hematopoietic stem cell transplantation were explored. RESULTS AND CONCLUSION:A total of 585 patients with hematologic diseases underwent allogeneic hematopoietic stem cell transplantation.92 patients died within 100 days after transplantation,with a mortality rate of 15.7%(92/585).The median age of death cases was 26.5 years old(1-56 years),and the median survival time of death cases was 48 days(0-97 days).Univariate analysis exhibited that age≥14 years old,acute graft-versus-host disease,grade IV acute graft-versus-host disease,bacterial bloodstream infection,as well as carbapenem-resistant organism bloodstream infection,were risk factors for overall survival within 100 days after allogeneic hematopoietic stem cell transplantation(P<0.05).Multivariate regression analysis showed that age≥14 years old,grades Ⅲ-Ⅳ acute graft-versus-host disease,bacterial bloodstream infection,and carbapenem-resistant organism bloodstream infections were independent risk factors for overall survival(within 100 days)in patients after allogeneic hematopoietic stem cell transplantation.Hazard ratios were 1.77(95%CI 1.047-2.991),7.926(95%CI 3.763-16.695),2.039(95%CI 1.117-3.722),and 3.389(95%CI 1.563-7.347),respectively.In conclusion,all-cause mortality rate after allogeneic hematopoietic stem cell transplantation is relatively high in the short term.A timely diagnosis and effective treatment of bacterial bloodstream infection and acute graft-versus-host disease are essential to improving allogeneic hematopoietic stem cell transplantation outcomes.

Objective To find potential biomarkers and analyzing metabolic pathways of the treatment by honey-processed Hedysari Radix,the cecal contents of rats with spleen-Qi deficiency were used as samples for analysis.Methods Sixty male SD rats were randomly divided into blank,model,experimental and control groups.The rats in other groups except the control group were carried out by using the three-factor compound modeling method of bitter-cold diarrhea,excessive exertion and hunger and satiety disorders.Experimental group was given 12.60 g·kg-1 honey-processed Hedysari Radix;control group was given 0.63 g·kg-1 lactobacillus bifidum triplex tabletsa;control and model groups received with equal volume of distilled water for a total of 15 days.Measure body weight,anal temperature,immune organ index of rats.Ultra-pressure liquid chromatography-quadrupole-exactive-mass spectrometry technology was used to measure the levels of endogenous metabolites in cecum contents.Orthogonal partial least squares discriminant analysis and database"Kyoto Encyclopedia of Genes and Genomes"were used to identify potential differential metabolites and possible metabolic pathways.Results After the intervention,the average body weight of the experimental,control,model and blank groups was(216.87±7.85),(210.96±9.03),(159.47±5.18)and(293.51±22.98)g;anal temperature was(36.14±0.48),(35.40±0.64),(34.50±0.78)and(36.61±0.34)℃;the thymus indexes were(1.19±0.20),(1.24±0.25),(0.47±0.15)and(1.31±0.21)mg·g-1;the spleen indexes were(1.95±0.33),(2.18±0.28),(1.61±0.27)and(2.29±0.24)mg·g-1.Compared with the model group,the above indexes of the experimental group and the control group were significantly increased(all P＜0.01).A total of 14 potential biomarkers of Honey-processed Hedysari Radix in treating spleen-Qi deficiency syndrome were screened out in this study,which mainly involved amino acid metabolism such as tryptophan and glutamate,riboflavin metabolism and adenosine 5'-monophosphate-activated protein kinase metabolism.Conclusion Honey-processed Hedysari Radix can further protect the intestinal mucosal barrier and reduce the intestinal inflammatory response by improving the metabolic level of cecum contents in rats with spleen-Qi deficiency in cecum contents,thus exerting the effect of strengthening the spleen and tonifying the Qi.

Objective:To investigate the clinicopathological characteristics of early gastric cancer with mixed histological staging, and to analyze the prognostic effect of endoscopic submucosal dissection (ESD) for early gastric cancer.Methods:Clinical data of early gastric cancer patients treated with ESD in Gansu Wuwei Cancer Hospital from January 2011 to March 2020 were collected, and clinicopathological characteristics of patients with mixed-type early gastric cancer were analyzed by descriptive statistical methods. The clinical effects and influencing factors of ESD on early gastric cancer were analyzed by logistic regression. Kaplan-Meier was used to estimate the survival rate, and log-rank test was used to compare the survival rate.Results:A total of 269 patients (280 lesions) were included in this study, including 216 males (80.30%) and 53 females (19.70%), with age of 60.43±8.01 years. There were 25 lesions (8.93%) of mixed early gastric cancer, 248 lesions (88.57%) of differentiated early gastric cancer, and 7 lesions (2.50%) of undifferentiated early gastric cancer. Compared with differentiated and undifferentiated early gastric cancer, the lesion site of mixed early gastric cancer was mainly located in the upper 1/3 of the stomach [64.00% (16/25), 40.73% (101/248) VS 0.00% (0/7), χ2=10.211, P=0.006], the proportion of the lesion size ≤2 cm was relatively small [52.00% (13/25), 80.65% (200/248) VS 85.71% (6/7), χ2=11.173, P=0.004], and the proportion of infiltration depth in the mucosa was lower [52.00% (13/25), 85.48% (212/248) VS 57.14% (4/7), χ2=20.019, P<0.001], the proportion of positive vertical resection margin was relatively high [20.00% (5/25), 2.82% (7/248) VS 0.00% (0/7), χ2=16.657, P<0.001], the proportion of vascular invasion was higher than that of differentiated carcinoma but lower than that of undifferentiated carcinoma [36.00% (9/25), 2.42% (6/248) VS 42.86% (3/7), χ2=58.413, P<0.001], the complete resection rate was lower [76.00% (19/25), 93.15% (231/248) VS 100.00% (7/7), χ2=9.497, P=0.009], the curative resection rate was lower than that of differentiated early gastric cancer, but higher than that of undifferentiated early gastric cancer [48.00% (12/25), 89.52% (222/248) VS 42.86% (3/7), χ2=39.757, P<0.001], and the proportion of eCura grade C2 was higher than that of differentiated cancer, but lower than that of undifferentiated cancer [48.00% (12/25), 5.65% (14/248) VS 57.14% (4/7), χ2=58.766, P<0.001]. The results of multivariate analysis showed that the larger lesions ( P=0.004, OR=0.539, 95% CI: 0.354-0.822) was the risk factor for curative resection. In terms of infiltration depth, mucosal ( P=0.001, OR=51.799, 95% CI: 5.535-84.768) and submucosal 1 ( P<0.001, OR=29.301, 95% CI: 24.694-73.972) were protective factors for curative resection compared with submucosal 2. In terms of differentiation degree, compared with mixed type, differentiated type ( P=0.024, OR=3.947, 95% CI: 1.195-13.032) was the protective factor for curative resection, while undifferentiated type ( P=0.443, OR=0.424, 95% CI: 0.048-3.788) showed no difference between curative resection and mixed type. During the follow-up, 7 patients died. The overall survival time was 114.42±0.97 months, and the 5-year survival rate was 97.10%. There was no significant difference in the survival rate of early gastric cancer patients with different degrees of differentiation ( χ2=0.434, P=0.805). The survival rate of early gastric cancer patients with or without curative resection was significantly different ( χ2=4.081, P=0.043). Conclusion:Mixed early gastric cancer patients show high margin positive rate, vascular infiltration, and less curative resection than differentiated early gastric cancer. Therefore, the process of treating mixed early gastric cancer should be more rigorous. The long-term survival prognosis of early gastric cancer after ESD treatment is promising.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Objective To observe the clinical effect of acupuncture combined with Shenqi Huoxue Decoction in the treatment of adenomyosis of qi deficiency and blood stasis type.Methods Seventy patients with adenomyosis of qi deficiency and blood stasis type were randomly divided into observation group and control group,35 cases in each group.The control group was treated with Levonorgestrel-releasing intrauterine system,and the observation group was treated with acupuncture combined with Shenqi Huoxue Decoction on the basis of the treatment of the control group.One menstrual cycle was a course of treatment,and the treatment lasted for three courses.After 3 months of treatment,the clinical efficacy of the two groups was evaluated,and the changes of Endometriosis Health Profile-5(EHP-5)score,serum superoxide dismutase(SOD)and catalase(CAT)were observed in the two groups before and after treatment.The changes of serum carbohydrate antigen CA125,carbohydrate antigen 199(CA199)and human epididymis protein 4(HE4)levels were compared before and after treatment between the two groups.Results(1)The total effective rate was 97.14％(34/35)in the observation group and 77.14％(27/35)in the control group.The clinical efficacy of the observation group was superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,the levels of serum CA125,CA199 and HE4 in the two groups were significantly improved(P＜0.05),and the improvement of serum CA1 25,CA199 and HE4 levels in the observation group was significantly superior to that in the control group,the difference was statistically significant(P＜0.05).(3)After treatment,the levels of serum SOD and CAT in the two groups were significantly improved(P＜0.05),and the improvement of serum SOD and CAT levels in the observation group was significantly superior to that in the control group,the difference was statistically significant(P＜0.05).(4)After treatment,the EHP-5 score of quality of life in the two groups was significantly improved(P＜0.05),and the EHP-5 score of quality of life in the observation group was significantly superior to that in the control group,the difference was statistically significant(P＜0.05).Conclusion Acupuncture combined with Shenqi Huoxue Decoction in the treatment of adenomyosis of qi deficiency and blood stasis type can significantly improve the clinical symptoms of patients,regulate the levels of SOD and CAT,so as to improve the quality of life of patients,and the curative effect is significant.

Objective To investigate the correlation between the level of N-terminal pro-Brain natriuretic peptide(NT-proBNP)and cardiorespiratory fitness following acute exposure to high altitude.Methods Forty-six subjects were recruited from the Second Affiliated Hospital of Army Medical University in June 2022,including 19 males and 27 females.After completing cardiopulmonary exercise test(CPET),serological detection of myocardial cell-related markers,and multiple metabolites at a plain altitude(300 meters above sea level),all subjects flew to a high-altitude location(3900 meters above sea level).Biomarker testing and CPET were repeated on the second and third days after arrival at high altitude.Changes in serum biomarker and key CPET indicators before and after rapid ascent to high altitude were compared,and the correlation between serum levels of various myocardial cell-related markers and metabolites and high altitude cardiorespiratory fitness was analyzed.Results Compared with the plain altitude,there was a significant decrease in maximal oxygen uptake after rapid ascent to high altitude[(25.41±6.20)ml/(kg.min)vs.(30.17±5.01)ml/(kg.min),P<0.001].Serum levels of NT-proBNP,Epinephrine(E),plasma renin activity(PRA),angiotensin Ⅱ(Ang Ⅱ),angiotensin-converting enzyme 2(ACE2)and leptin(LEP)significantly increased,with all differences being statistically significant(P<0.05)after acute high altitude exposure.In contrast,no statistically significant differences were observed for creatine kinase MB(CK-MB),cardiac troponin I(cTnI),myoglobin(Myo)and norepinephrine(NE)(P>0.05).Correlation analysis showed a significant negative correlation between NT-proBNP at plain altitude(r=-0.768,P<0.001)and at high altitude(r=-0.791,P<0.001)with maximal oxygen uptake at high altitude.Multivariate linear regression analysis indicated that maximal oxygen uptake at plain altitude(t=2.069,P=0.045),NT-proBNP at plain altitude(t=-2.436,P=0.020)and at high altitude(t=-3.578,P=0.001)were independent influencing factors of cardiorespiratory fitness at high altitude.Conclusion Cardiorespiratory fitness significantly decreases after rapid ascent to high altitude,and the baseline NT-proBNP level at plain altitude is closely related to cardiorespiratory fitness at high altitude,making it a potential predictor indicator for high altitude cardiorespiratory fitness.

Objective:To understand the current clinical practice status of evidence on blood glucose management in ICU patients with insulin intravenous infusion, analyze barriers and formulate action strategies, so as to provide reference for the translation of evidence into clinical practice.Methods:Based on the clinical evidence application model of the Joanna Briggs Institute (JBI) Evidence-Based Health Care Center, clinical nursing problems were identified, literature search, evaluating and summarizing evidence were carried out, and review indicators and methods were developed. From July to August 2023, convenience sampling was used to select 42 nurses and 80 patients with insulin intravenous infusion from the comprehensive ICU of Wuxi Second People's Hospital as participants for baseline review. Barriers were analyzed and change strategies were developed based on baseline review results.Results:A total of 16 pieces of evidence were introduced regarding blood glucose management in ICU patients with insulin intravenous infusion. Nineteen review indicators were formulated, of which 13 had a compliance rate of less than 60%. Analysis identified 18 barriers and 13 facilitators. Sixteen change strategies were developed based on barriers and facilitators.Conclusions:There is still a significant gap between the evidence of ICU insulin intravenous infusion blood glucose management and clinical practice. Evidence-based practice programs should be constructed based on intervention strategies to effectively promote the application of evidence in clinical practice.

Objective:To investigate the effect of oral immunotherapy with donor human milk on feeding tolerance in premature infants with very low birth weight.Methods:A total of 94 extremely low birth weight preterm infants admitted to the neonatal Intensive Care Unit of Cangzhou People's Hospital from August 2022 to February 2024 were selected, These infants were randomized at 1:1 into 2 groups (47 cases each) using random number method. The control group were given oral 0.9% sodium chloride (oral drip), while the experimental group were given donor human milk (oral drip). General information were collected, including gender, delivery method, twins or not, small for gestational age or not, birth weight, gestational age, intestinal feeding of dairy products, and so on. Total intestinal feeding time, length of hospital stay and feeding intolerance were compared between groups.Results:The total intestinal feeding time and length of hospital stay were significantly shorter in the experimental group compared with the control group ( P<0.05). The incidence of feeding intolerance in the experimental group was also lower than that in the control group ( P<0.05). Conclusion:Oral immunotherapy with donor human milk can improve the feeding tolerance in premature infants with very low birth weight and shorten the hospital stay.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To explore the predictive value of combined detection of immunoglobulin binding protein 1 (IGBP 1) in serum and urine in lupus nephritis (LN). Methods A total of 60 LN patients were selected as LN group, and 60 SLE erythematosus (SLE) patients in the same period were selected as SLE group, the serum IGBP 1 and urinary IGBP 1 levels between the two groups were compared, and the value of serum IGBP 1, urinary IGBP 1 and their combination in predicting LN was analyzed. Results Serum IGBP 1 and urinary IGBP 1 in the LN group were significantly higher than those in the SLE group (P < 0.05). Binary Logistic regression analysis showed that serum IGBP 1 and urinary IGBP 1 were risk factors for LN (P < 0.05). Receiver Operating Characteristic (ROC) curve revealed that the area under the curve (AUC) for serum IGBP1, urinary IGBP1, and their combined detection for LN was 0.856, 0.834, and 0.902, respectively. The Youden index was 0.533, 0.533, and 0.666, respectively. The sensitivity and specificity of serum IGBP1 were 85.0% and 68.3%, respectively. The sensitivity and specificity of urinary IGBP1 were 53.3% and 100.0%, respectively. The sensitivity and specificity of the combined detection were 78.3% and 88.3%, respectively. Conclusion Serum IGBP 1 and urinary IGBP 1 are highly expressed in LN patients, and their combination has a high predictive value for LN.
