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.

The incidence of decreased ovarian reserve(DOR)is gradually increasing,with fluctuations in hormone levels causing a series of clinical syndromes.Among these,sleep disorders stand out as prominent symptoms,clinically manifested by difficulties in falling asleep,shortened sleep duration,and poor sleep quality,severely impacting the physical and mental health as well as the quality of life of women.Clinical observations have found a close relationship between decreased ovarian reserve and sleep disorders,where the two interact causally and reciprocally.Western medicine primarily focuses on improving behavioral cognition,administering sedatives and hypnotics,and hormone replacement therapy,albeit with certain limitations in efficacy.Traditional Chinese medicine emphasizes holistic views and syndrome differentiation in treatment,offering low side effects and unique advantages.This review summarizes recent literature on the research progress of sleep disorders and DOR from both Western and traditional Chinese medicine perspectives,providing reference for clinical treatment.

Objective:To analyze the risk factors for heart failure in patients with hemodialysis, and to construct a nomogram model.Methods:The clinical data of 218 patients with hemodialysis in Xianyang Central Hospital from January 2021 to April 2022 were retrospectively analyzed. Among them, 83 cases developed heart failure (heart failure group), and 135 cases did not develop heart failure (control group). The relevant clinical data were recorded, including age, sex, body mass index, disease duration, concurrent infection, blood calcium, blood phosphorus, soluble CD 146 (sCD 146), soluble growth-stimulated expression gene 2 protein (sST2), N-terminal brain natriuretic peptide precursor (NT-proBNP), time-averaged urea concentration (TACurea), tumor necrosis factor α (TNF-α), blood creatinine and 24 h urine volume. Receiver operating characteristic (ROC) curve was used to analyze the efficacy of each index in predicting heart failure in patients with hemodialysis. Multivariate Logistic regression was used to analyze the independent risk factors of heart failure in patients with hemodialysis. R language software 4.0 "rms" package was used to construct the nomogram model for predicting the heart failure in patients with hemodialysis, the calibration curve was internally validated, and the decision curve was used to evaluate the predictive efficacy of the nomogram model. Results:There were no statistical difference in gender composition, age, body mass index, disease duration, 24 h urine volume and blood creatinine between the two groups ( P>0.05); the rate of concurrent infection, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea in heart failure group were significantly higher than those in control group: 39.76% (33/83) vs. 8.89% (12/135), (1.53 ± 0.34) mmol/L vs. (1.27 ± 0.24) mmol/L, (43.60 ± 10.24) μmol/L vs. (28.08 ± 7.99) μmol/L, (49.00 ± 9.41) μg/L vs. (34.53 ± 8.05) μg/L, (38.57 ± 6.79) μg/L vs. (29.72 ± 5.64) μg/L, (5.18 ± 0.92) μg/L vs. (4.07 ± 1.13) μg/L and (24.28 ± 4.37) mmol/L vs. (17.96 ± 2.52) mmol/L, the blood calcium was significantly lower than that in control group: (1.95 ± 0.36) mmol/L vs. (2.31 ± 0.39) mmol/L, and there were statistical differences ( P<0.01). ROC curve analysis result showed that the optimal cut-off values of blood calcium, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea for heart failure in patients with hemodialysis were 2.01 mmol/L, 1.42 mmol/L, 34.15 μmol/L, 40.37 μg/L, 35.37 μg/L, 4.33 μg/L and 20.74 mmol/L. Multivariate Logistic regression analysis result showed that the blood calcium (≤2.01 mmol/L), blood phosphorus (>1.42 mmol/L), sCD 146 (>34.15 μmol/L), sST2 (>40.37 μg/L), NT-proBNP (>35.37 μg/L), TNF-α (>4.33 μg/L) and TACurea (>20.74 mmol/L) were independent risk factors for heart failure in patients with hemodialysis ( OR = 1.183, 1.582, 1.915, 1.105, 1.459, 1.347 and 1.717; 95% CI 1.102 to 1.191, 1.274 to 1.868, 1.716 to 2.105, 1.072 to 1.141, 1.225 to 1.703, 1.132 to 1.574 and 1.482 to 1.935; P<0.05 or <0.01). The blood calcium, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea were used as predictors to construct a nomogram model for predicting heart failure in patients with hemodialysis. Internal validation result showed that the nomogram model predicted the heart failure with good concordance in patients with hemodialysis (C-index = 0.811, 95% CI 0.675 to 0.948); the nomogram model predicted the heart failure in patients with hemodialysis at a threshold>0.18, provided a net clinical benefit, and all had higher clinical net benefits than blood calcium, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea. Conclusions:The nomogram model constructed based on blood calcium, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea has better clinical value in predicting the heart failure in patients with hemodialysis.

Objective: To analyze the epidemiological characteristics of norovirus-caused acute gastroenteritis outbreaks in China, identify the factors influencing the scale of outbreaks, and provide scientific evidences for early control of norovirus infection outbreaks. Methods: The descriptive epidemiological analysis approach was applied to analyze the incidence of national norovirus infection outbreaks by using the data from the Public Health Emergency Event Surveillance System in China from January 1, 2007 to December 31, 2021. The unconditional logistic regression model was applied to analyze the risk factors that affected the outbreaks' scale. Results: A total of 1 725 norovirus infection outbreaks were recorded in China from 2007 to 2021, with an upward trend in the number of the reported outbreaks. The southern provinces had their annual outbreak peaks from October to March; the northern provinces had two outbreak peaks from October to December and from March to June annually. The outbreaks occurred mainly in southeastern coastal provinces with a trend of gradual spread to central, northeastern and western provinces. The outbreaks mainly occurred in schools and childcare setting (1 539 cases, 89.22%), followed by enterprises and institutions (67 cases, 3.88%) and community households (55 cases, 3.19%). Human to human transmission was the main infection route (73.16%), and norovirus GⅡ genotype was the predominate pathogen causing the outbreaks (899 cases, 81.58%). The time interval between the onset of the primary case and the outbreak reporting M (Q₁, Q₃) was 3 (2, 6) days and the case number of the outbreak M (Q₁, Q₃) was 38 (28, 62). The timeliness of outbreak reporting was improved in recent years and the scale of the outbreaks showed a decreasing trend over the years, the differences in reporting timeliness and outbreak scale among different settings were significant (P<0.001). The factors that affected outbreaks' scale included the outbreak setting, transmission route, outbreak reporting timeliness and type of living areas (P<0.05). Conclusions: From 2007 to 2021, the number of the norovirus-caused acute gastroenteritis outbreaks increased in China and the more areas were affected. However, the outbreak scale showed a decreasing trend and the outbreak reporting timeliness was improved. It is important to further improve the surveillance sensitivity and reporting timeliness for the effective control of the outbreak scale.

Diabetic kidney disease (DKD) is the primary cause of mortality among diabetic patients. With the increasing prevalence of diabetes, it has become a major concern around the world. The therapeutic effect of clinical use of drugs is far from expected, and therapy choices to slow the progression of DKD remain restricted. Therefore, research on new drugs and treatments for DKD has been a hot topic in the medical field. It has been found that rhein has the potential to target the pathogenesis of DKD and has a wide range of pharmacological effects on DKD, such as anti-nephritis, decreasing blood glucose, controlling blood lipids and renal protection. In recent years, the medical value of rhein in the treatment of diabetes, DKD and renal disease has gradually attracted worldwide attention, especially its potential in the treatment of DKD. Currently, DKD can only be treated with medications from a single symptom and are accompanied by adverse effects, while rhein improves DKD with a multi-pathway and multi-target approach. Therefore, this paper reviews the therapeutic effects of rhein on DKD, and proposes solutions to the limitations of rhein itself, in order to provide valuable references for the clinical application of rhein in DKD and the development of new drugs.

The pharmaceutical manufacturing model is gradually changing from intermittent manufacturing to continuous manufacturing and intelligent manufacturing. This paper briefly reviewed the supervision and research progress in continuous pharmaceutical manufacturing in China and abroad and described the definition and advantages of continuous pharmaceutical manufacturing. The continuous manufacturing of traditional Chinese medicine(TCM) at the current stage was summarized in the following three terms: the enhancement of the continuity of intermittent manufacturing operations, the integration of continuous equipment to improve physical continuity between units, and the application of advanced process control strategies to improve process continuity. To achieve continuous manufacturing of TCM, the corresponding key technologies, such as material property characterization, process modeling and simulation, process analysis technology, and system integration, were analyzed from the process and equipment, respectively. It was proposed that the continuous manufacturing equipment system should have the characteristics of high speed, high response, and high reliability, "three high(H~3)" for short. Considering the characteristics and current situation of TCM manufacturing, based on the two dimensions of product quality control and production efficiency, a maturity assessment model for continuous manufacturing of TCM, consisting of operation continuity, equipment continuity, process continuity, and quality control continuity, was proposed to provide references for the application of continuous manufacturing technology for TCM. The implementation of continuous manufacturing or the application of key continuous manufacturing technologies in TCM can help to systematically integrate advanced pharmaceutical technology elements and promote the uniformity of TCM quality and the improvement of production efficiency.

Analytic hierarchy process(AHP)-entropy weight method(EWM) and network pharmacology were employed to identify the potential quality markers(Q-markers) of Gei Herba. According to the new concept of Q-markers in traditional Chinese medicine(TCM), the AHP-EWM was applied to quantitatively identify the Q-markers of Gei Herba. The AHP was used for the weight analysis of primary indicators(factor layer), and the EWM for the analysis of literature and experimental data of secondary indicators(control layer). In addition, network pharmacology was employed to build the "component-target-disease-efficacy" network for Gei Herba, and the components showing strong associations with the Qi-replenishing, spleen-invigorating, blood-tonifying, Yin-nourishing, lung-moistening, and phlegm-resolving effects of Gei Herba were screened out. According to the results of AHP-EWM and network pharmacology, four components, i.e., ellagic acid, gallic acid, gemin G, and gemin C, were finally identified as potential Q-markers of Gei Herba. In this study, the AHP-EWM and network pharmacology were employed to screen the Q-markers of Gei Herba, which provided ideas for the quantitative evaluation and identification of Q-markers of TCM.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

Herb pair， a common form of compounding in Chinese medicinal prescriptions， reflects the experience of pharmacists in clinical medication in the past. It is characterized by simple composition while has the basic characteristics of Chinese medicine compounding. The combination of two medicinal herbs can enhance effect or reduce toxicity. Coptidis Rhizoma （CR） has the effects of clearing heat， drying dampness， purging fire， and removing toxin. Euodiae Fructus （EF） is acrid， bitter， and hot-natured， which can not only warm the Yang Qi in spleen and stomach to dissipate cold and relieve pain， but also descend stomach Qi and prevent vomiting. Furthermore， it can warm the liver and kidney. CR and EF form a typical cold-heat herb pair， which oppose and yet also complement each other. Specifically， their cold and heat natures interact with each other to clear liver fire， harmonize stomach for descending adverse Qi， relieve depression， and dissipate mass. CR clears the intestine and stops dysentery， while EF warms the middle and promotes the circulation of Qi. The combination of them can thus clear heat， dry dampness， and relieve pain. Modern pharmacological studies have demonstrated that CR-EF has not only significant efficacy against digestive system diseases but also good anti-cancer， anti-inflammatory， anti-ulcer， and lipid-lowering activities. Therefore， the article summarized the effect enhancement and toxicity reduction of the herb pair at the levels of cellular molecule， isolated organ， and whole animal， and clarified the mechanism of its pharmacological action. It will provide a theoretical basis for further development and clinical use of the herb pair.

Traditional Chinese medicine, as a complementary and alternative medicine, has been practiced for thousands of years in China and possesses remarkable clinical efficacy. Thus, systematic analysis and examination of the mechanistic links between Chinese herbal medicine (CHM) and the complex human body can benefit contemporary understandings by carrying out qualitative and quantitative analysis. With increasing attention, the approach of network pharmacology has begun to unveil the mystery of CHM by constructing the heterogeneous network relationship of "herb-compound-target-pathway," which corresponds to the holistic mechanisms of CHM. By integrating computational techniques into network pharmacology, the efficiency and accuracy of active compound screening and target fishing have been improved at an unprecedented pace. This review dissects the core innovations to the network pharmacology approach that were developed in the years since 2015 and highlights how this tool has been applied to understanding the coronavirus disease 2019 and refining the clinical use of CHM to combat it.
