Malignant tumor is a serious and difficult disease threatening human health， which has a high morbidity and mortality rate worldwide. Traditional Chinese medicine has unique advantages in improving the therapeutic effect of malignant tumors and alleviating adverse reactions. Traditional Chinese medicine believes that Qi deficiency and blood stasis are important pathogeneses in the development of malignant tumors， and the method of supplementing Qi and activating blood is an effective strategy for treating malignant tumors. Astragali Radix， sweet in taste and warm in nature， has effects of tonifying Qi and rising Yang， strengthening the exterior and reducing sweat， promoting fluid and nourishing blood. Curcumae Rhizoma， acrid and bitter in taste and warm in nature， has the effects of promoting Qi and breaking blood stasis， eliminating mass， and relieving pain. Astragali Radix-Curcumae Rhizoma， as the classic herb pair of invigorating Qi and activating blood， has a clear effect on inhibiting tumor growth and metastasis. Studies have shown that Astragali Radix-Curcumae Rhizoma contains astragalus polysaccharide， astragaloside， calycosin， formononetin， curcumin， β-elemene， curcumenol， curcumenone， curcumendione， gemacrone， and other anti-tumor active ingredients. It can significantly inhibit the occurrence and development of liver cancer， colorectal cancer， gastric cancer， lung cancer， ovarian cancer， cervical cancer， breast cancer， and other cancers and has the advantages of superposition effect， synergistic complementarity， and increased dissolution compared with single herb and monomer of Chinese traditional herbs and has been widely valued in the field of TCM anti-cancer. Its anti-tumor mechanism includes inhibition of tumor cell proliferation， promotion of tumor cell apoptosis and autophagy， anti-invasion and metastasis， regulation of immune function， and enhancement of anti-tumor drug sensitivity. By combining Chinese and foreign literature， the compatibility effect and anti-tumor mechanism of Astragali Radix-Curcumae Rhizoma were summarized， and then scientific compatibility of these two herbs was expounded， in order to provide a useful reference for clinical application and future research of Astragali Radix-Curcumae Rhizoma.

Objective To develop a nomogram for predicting the risks of early anastomotic recurrence(EAR)after primary bowel resection in patients with Crohn's disease(CD).Methods The patients with CD under-going preoperative magnetic resonance enterography(MRE)and primary bowel resection were enrolled in this retrospective study and divided into an EAR group(18 patients)and EAR-free group(12 patients).The EAR group included the patients having an endoscopic Rutgeerts score of≥I2 month or the need for anastomotic resection within 12 months after surgery.All the 38 indexes including preoperative demographic characteristics,laboratory examina-tions,multi-parameter MRE features of the resected intestine and its adjacent mesentery,histological findings,and postoperative pharmacotherapy were analyzed.Least absolute shrinkage and selection operator(LASSO)regression and multivariate binary logistic regression analysis were performed to identify independent risk factors to be incorpo-rated into the nomogram for predicting the risks of early anastomotic recurrence and the prediction performance was evaluated.Results Mesenteric creeping fat index on MRE and comb sign were independent risks of EAR,with a concordance index of 0.882(95%CI:0.764～1).The calibration plot revealed a strong relationship between actual observation and predicted probability of EAR.Conclusions The preoperative MRE-based nomogram may be a potential tool for predicting EAR following surgery in patients with CD,which is beneficial to individual management in those patients.It provides reference for the formulation of early postoperative individualized drug adjuvant therapy in patients at high risk of EAR.

Objective:To understand the epidemiological characteristics and incidence trend of severe fever with thrombocytopenia syndrome (SFTS) in China.Methods:The incidence data of SFTS in China from 2018 to 2021 were collected from Chinese Disease Prevention and Control Information System for a statistical and descriptive epidemiological analysis by using software such as Excel 2016, Joinpoint 5.0.2, SPSS 26.0, and GraphPad Prism 8.0, especially, the SFTS cases reported monthly by key provinces were analyzed.Results:From 2018 to 2021, a total of 8 835 SFTS cases were reported in 25 provinces and the annual incidence showed an upward trend. The distribution of SFTS cases showed clustering, but the cases were mainly sporadic ones. The cases began to increase in March, mainly occurred during April to October (96.79%,8 551/8 835), and peaked during May to July. The cases were mainly distributed in middle-aged and old farmers, and slight more cases were women. The average case fatality rate was 5.38%, which varied greatly with areas. The case fatality rate tended to increase with age.Conclusion:From 2018 to 2021, the epidemiological characteristics of SFTS in China remained stable, but the number of reported cases gradually increased and the distribution showed an expanding trend, to which close attention should be paid.

ObjectiveTo provide scientific support for the compilation of high-quality anti-nuclear， biological， and chemical （NBC） medical textbooks in China by retrieving books in the field of biological weapons defense in China， summarizing the publication time and distribution of publishing institutions， and categorizing content and key points of related books. MethodsRelevant subject terms in the field of biological weapons defense were searched through the official website of China National Digital Library and other websites， up until December 31， 2023， and were limited to books. Topic analysis was conducted on the introductions and contents of the books using the latent Dirichlet allocation （LDA） model. The number of topics was determined based on perplexity， and topics were identified according to the intertopic distance map， followed by a qualitative description of the core content of each topic. ResultsA total of 104 books were included in this study， among which four were identified as higher educational textbooks. The volume of publications increased during the periods 2002‒2004 and 2020‒2023. Research institutions accounted for the highest percentage of publishers （37.78%）， and 56.67% of the publishers were military institutions. The study identified six topics： "distribution， defense， and response to biological weapons"， "category， diagnosis， and treatment of biological warfare agents"， "response to biological public health emergencies"， "status of nuclear， biological， and chemical weapons internationally"， "biosafety risk management and prevention and control"， and "technologies and equipment related to biological hazard identification". ConclusionThere are few books in the field of biological weapons defense in China and the content is relatively outdated. In the future， the preparation of teaching materials should be aimed at practical emergency handling techniques for biological weapons， enhance the emphasis on biological weapons detection and biological warfare early warning， improve the fundamental theories at different training levels， and timely update the current research status in the field.

AIM: To determine the patient-related risk factors for pain during phacoemulsification.METHODS: Retrospective case-control study. A total of 62 patients(62 eyes)diagnosed as cataract in the First Affiliated Hospital of Zhengzhou University from December 2023 to January 2024 were included. The numeric rating scale was used to assess the pain level within 5 min postoperatively. The highest pain value was used as the primary outcome during the procedure. Based on pain values, patients were divided into pain group(n=25)and pain-free group(n=37). Subsequently, patients in the pain group were further divided into mild(n=16), moderate(n=7), and severe groups(n=2). Spearman correlation and Logistic regression analysis were conducted to determine risk factors for pain during the phacoemulsification.RESULTS: Binary Logistic regression showed preoperative sleep durations and times of operations were important risk factors for intraoperative pain(all P<0.05). Spearman analysis showed that intraoperative pain was negatively correlated with sleep duration(rs=-0.386, P=0.002), and positively correlated with times of operations(rs=0.421, P<0.001). The results of the ordinal Logistic regression analysis showed that for every additional hour of sleep, the likelihood of experiencing one higher level of intraoperative pain decreased by 37.60%(OR=0.376, P=0.014). In contrast, the times of operations did not show a statistically significant difference(P=0.083). Receiver operating characteristic curve showed a joint prediction model of sleep duration and operative times with an area under the curve of 0.809, 84% sensitivity, and 73% specificity.CONCLUSION: The intraoperative pain during phacoemulsification is negatively correlated with sleep duration and positively correlated with times of operations.

Objective To explore the effects of optimized nutrition intervention scheme on nutritional status and clinical outcome during transplantation in the patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods Seventy inpatients with allo-HSCT in this hospital from January to December 2022 were selected as the study subjects and divided into the control group and intervention group by the random number table method,35 cases in each group.The control group conducted the conventional nutritional intervention and the intervention group conducted the optimized nutritional intervention.The nutri-tional indicators[body weight,patient-generated subjective global assessment (PG-SGA),energy and protein intake],levels of total protein (TP),albumin (ALB) and prealbumin (PA),hospitalization duration,hospitali-zation costs and adverse reactions occurrence were compared between the two groups.The differences in the nutritional status and clinical outcomes in the tow groups were comprehensively evaluated.Results Compared with the control group,the body weight decrease ranges in entering the laminar flow ward and on 60 d of transplantation in the intervention group were much less[3.10(1.10,4.80)kg vs. 4.30(3.10,6.70)kg;3.20 (1.00,5.50)kg vs. 4.15(3.33,7.88)kg],the PG-SGA score was lower[(10.43±3.25)points vs. (13.00±3.05) points],the PA level was higher[(189.63±51.29)mg/L vs. (163.83±48.03)mg/L],the energy and protein oral intakes were much more[(753.99±350.66)kcal vs. (539.96±247.65)kcal;(33.87±15.87)g vs. (20.43±12.57)g],the diarrhea occurrence rate was lower (14.3％ vs. 37.1％),and the differences were statistically significant (P<0.05).Conclusion Optimizing the nutritional intervention during allo-HSCT pe-riod is beneficial to improve the nutritional status of the patients,and reduce the incidence rate of adverse reac-tions.

Adipose progenitor cells(APCs) represent a prominent stromal cellular component of adipose tissue and are now identified as highly heterogenous populations. However, the role of APCs in regulating systemic metabolism remains unknown. Using single cell RNA-sequencing, we investigated the role of the APC subpopulations in regulating development of type 2 diabetes. CD9 + CD55 low APCs are the novel subset identified in this study, which is significantly increased in type 2 diabetic patients. Transplantation of these cells from type 2 diabetic patients into adipose tissue caused glycemic disturbance in mice. Depletion of pathogenic APCs improved obesity-related glycemic disturbance. Collectively, our data provide deeper insights into human APC functionality and highlights APCs as a potential therapeutic target to combat type 2 diabetes. This study has been published in Nature Communications, 2024, 15(1): 4827.

Objective:To investigate the status quo and influencing factors of health self-management ability of scientific and technological workers in Shanxi Province.Methods:This study was a cross-sectional study. Using the general situation questionnaire and the adult health self-management ability evaluation scale, 467 scientific and technological workers who received physical examination in the First Hospital of Shanxi Medical University from January 2022 to September 2022 were investigated by questionnaire, and their height, weight, body mass index, fasting blood glucose, blood lipids and blood uric acid were collected on the day of physical examination. Multiple linear regression analysis was used to explore the influencing factors of health self-management ability, and Pearson and Spearman correlation analysis was used to analyze the correlation between health self-management ability and examination items.Results:The total score of health self-management ability of 467 scientific and technological workers was (153.7±16.5). The results of multiple linear regression showed that the type of medical insurance, self-assessment of health status, staying up late, and sleep quality were independent influencing factors of health self-management ability ( R2=0.141, adjusted R2=0.120, F=6.771; P<0.001). Health self-management ability was positively correlated with high-density lipoprotein ( r=0.114), behavioral subscale was positively correlated with high-density lipoprotein ( r=0.107), environmental subscale was negatively correlated with uric acid ( r=-0.103), triglyceride ( r=-0.118), and positively correlated with high-density lipoprotein ( r=0.129), and cognitive subscale was negatively correlated with triglyceride ( r=-0.125), all of which were statistically significant ( P<0.05). Conclusions:The ability of health self-management of scientific and technological workers in Shanxi Province belongs to the upper middle level, which is affected by the type of medical insurance, the self-assessment of health status, staying up late, and the quality of sleep. It is suggested that the ability of health self-management of scientific and technological workers can be improved by strengthening their health beliefs, providing a more convenient working environment, reducing the frequency of staying up late, and improving their sleep quality.
