This paper summarizes Professor SHI Zaixiang's clinical experience in treating high fever caused by sepsis using Chaihu Guizhi Ganjiang Decoction （柴胡桂枝干姜汤）. He holds that the key pathogenesis of sepsis involves constrained heat in the shaoyang and internal accumulation of water and fluids. The clinical manifestations such as high fever， chills， and alternating sensations of cold and heat are attributed to pathogenic heat constrained in the shaoyang. Meanwhile， soft tissue edema and serous cavity effusions are due to shaoyang dysfunction and internal water retention. In clinical practice， treating sepsis-related high fever requires addressing both the shaoyang-constrained heat and the associated edema and effusions. The therapeutic approach focuses on harmonizing the shaoyang and resolving internal fluids， using Chaihu Guizhi Ganjiang Decoction as the base formula with flexible modifications. Professor SHI emphasizes that this formula shows a rapid antipyretic effect， particularly in cases where multiple anti-infective treatments have failed.

OBJECTIVE To investigate the pharmaceutical affairs management in healthcare institutions from Haidian district of Beijing， and propose countermeasures and suggestions for improving the related work. METHODS The current status of pharmaceutical affairs management in 66 healthcare institutions from Haidian district of Beijing was surveyed through on-site inspections， and the results were statistically analyzed. The inspection items included six special projects： pharmaceutical affairs management and organizational structure of pharmacy departments； drug quality management and control， prescription review， clinical application management of antimicrobial drugs， management of adverse drug events， and management of special drugs. These areas were further divided into a total of 27 specific inspection sub-items. RESULTS & CONCLUSIONS The total proportion of healthcare institutions that fully complied or basically complied with each special project was 90.9%， 97.0%， 86.3%， 90.9%， 90.9%， and 96.9%， respectively. The overall comparison among healthcare institutions that fully or substantially met the standards across medical institutions at different levels showed that the performance of tertiary healthcare institutions was better than that of secondary and primary healthcare institutions. The pharmaceutical affairs management in healthcare institutions within the jurisdiction was proceeding in an orderly manner. There is still room for improvement in further establishing and perfecting the functions of the pharmaceutical affairs management committee， implementing the 2021 Edition of Management Regulations for β -lactam Antimicrobial Skin Tests， enforcing the adverse drug reaction management system， and strengthening the refined management of narcotics and psychotropic drugs.

ObjectiveTo investigate and analyze an outbreak of rotavirus infectious diarrhea in a prison in Chongqing Municipality, to provide a basis for adult rotavirus surveillance and prevention, and to explore the public health problems in special settings. MethodsA retrospective survey was conducted to collect and analyze data on individual cases with diarrheal disease on-site. The clinical characteristics, as well as the temporal, spatial and geographical distribution patterns of the epidemic were described. Multi-pathogen detection tests were conducted both on diarrhea cases and environmental samples, with viral genotyping performed on positive samples. A case-control analysis was performed to identify the causes of the outbreak, and an SEIR model was adopted to predict the outbreak trend and evaluate the effectiveness of interventions. ResultsA total of 65 cases were found among the inmates, with an attack rate of 2.03%. The predominant clinical manifestations included diarrhea (89.23%), watery stool (73.85%), and dehydration (18.46%). The epidemic curve indicated a “human-to-human” transmission pattern, with an average incubation period of 5‒6 days. The attack rates among chefs in the main canteen (80.00%, 8/10) and caterers (28.33%, 17/60) were significantly higher than those of other inmates （P<0.05）. Multi-pathogen polymerase chain reaction (PCR) testing detected positive for group A rotavirus, with the viral genotyping identified as G9P [8] strain. Factors such as unprotected "bare-handed" food distribution among cases with diarrhea (OR=9.512, 95%CI: 4.261‒21.234) and close contact with diarrhea cases (OR=3.656, 95%CI: 1.719‒7.778) were the possible cause of the outbreak. The SEIR model (r₀=5, α=0.3, β₁=0.08, β₂=0.04) was constructed using prison inmates as susceptible population, aiming at fitting the initial transmission trend of the outbreak, and the epidemic rate declined rapidly after intervention measures were implemented (r_t≈0). ConclusionThis rare rotavirus infection diarrhea outbreak among adults in confined settings suggests that the construction of public health prevention and control systems in prison may be overlooked. Cross infection during meal processing and distribution in the canteens of such settings is likely to be the cause of the outbreak. Given the potential neglect of public heath system construction in special settings, it is imperative to enhance the surveillance and monitoring of rotavirus and other intestinal multi-pathogens among adults, as well as the construction of public health prevention and control systems in these special settings.

Objective: To investigate the epidemiological characteristics of hepatitis E in Shaoxing City, Zhejiang Province from 2006 to 2024, so as to provide the evidence for the prevention and control of hepatitis E. Methods: Data on hepatitis E incidence in Shaoxing City from 2006 to 2024 were collected through the Surveillance System of China Information System for Disease Control and Prevention. The epidemiological characteristics were analyzed using descriptive epidemiological methods. The trend in hepatitis E incidence was analyzed using the average annual percent change (AAPC) and annual percent change (APC). The spatial-temporal clustering characteristics of hepatitis E incidence were identified using spatial-temporal scanning analysis. Results: A total of 2 408 hepatitis E cases were reported in Shaoxing City from 2006 to 2024, with an average annual reported incidence of 2.55/100 000. The overall trend was not statistically significant (AAPC=3.181%, P>0.05). Specifically, it showed an upward trend from 2006 to 2011 (APC=17.371%, P<0.05), a downward trend from 2011 to 2019 (APC=-12.497%, P<0.05), and an upward trend from 2019 to 2024 (APC=18.076%, P<0.05). The epidemic season of hepatitis E was from January to May, with seasonal indices of 122.09%, 118.60%, 145.02%, 129.57%, and 106.15%, respectively. The top three average annual reported incidences were identified in Zhuji City, Xinchang County, and Shengzhou City, with rates of 4.18/100 000, 2.85/100 000, and 2.74/100 000, respectively. The average annual reported incidence of hepatitis E was higher in males than in females (3.52/100 000 vs. 1.56/100 000, P<0.05). A relatively large number of hepatitis E cases were reported among individuals aged 40-<70 years, with 1 639 cases (68.06%). Among them, the group aged 60-<70 years had the highest average annual reported incidence of hepatitis E, at 4.92/100 000. Farmers constituted the predominant occupational group, accounting for 1 515 cases (62.92%). Spatial-temporal scanning analysis identified two clusters in Shaoxing City from 2006 to 2024. The class Ⅰ cluster was located in Shengzhou City, with aggregation time from January 1, 2011 to May 1, 2014. The class Ⅱ cluster was located in Xinchang County, with aggregation time from December 1, 2012 to March 31, 2013. Conclusions The reported incidence of hepatitis E in Shaoxing City from 2006 to 2024 exhibited a pattern of an initial increase, followed by a decrease, and then a subsequent rise. The disease demonstrated higher prevalence during the winter and spring seasons. Key populations for targeted control and prevention include males, individuals aged 40-<70 years, and farmers. Shengzhou City and Xinchang County were identified as high-risk areas.

This paper reports a case of disseminated intravascular coagulation(DIC) that occurred early after hybrid surgery for type B aortic dissection with an aortic arch aneurysm. Through analyzing the clinical manifestations, imaging findings, and treatment response of the patient, we propose that massive false-lumen thrombosis may serve as a critical trigger for early postoperative coagulation activation leading to DIC. Corresponding treatment strategies are suggested to enhance clinicians' ability to recognize and manage this critical condition.

Traumatic brain injury (TBI) is intricately linked to the most severe clinical manifestations of brain damage. It encompasses dynamic pathological mechanisms, including hemodynamic disorders, excitotoxic injury, oxidative stress, mitochondrial dysfunction, inflammation, and neuronal death. This review provides a comprehensive analysis and summary of biomaterial-based tissue engineering scaffolds and nano-drug delivery systems. As an example of functionalized biomaterials, nano-drug delivery systems alter the pharmacokinetic properties of drugs. They provide multiple targeting strategies relying on factors such as morphology and scale, magnetic fields, pH, photosensitivity, and enzymes to facilitate the transport of therapeutics across the blood-brain barrier and to promote selective accumulation at the injury site. Furthermore, therapeutic agents can be incorporated into bioscaffolds to interact with the biochemical and biophysical environment of the brain. Bioscaffolds can mimic the extracellular matrix environment, regulate cellular interactions, and increase the effectiveness of local treatments following surgical interventions. Additionally, stem cell-based and exosome-dominated extracellular vesicle carriers exhibit high bioreactivity and low immunogenicity and can be used to design therapeutic agents with high bioactivity. This review also examines the utilization of endogenous bioactive materials in the treatment of TBI.

Sugarcane (Saccharum spp.) is an important sugar crop. Biotic and abiotic stresses such as diseases, cold, and drought are major factors limiting sugarcane production. β-1,3-glucanase (EC 3.2.1.39), a member of the pathogenesis-related protein family, plays an essential role not only in the plant defenses against pathogens but also in plant growth, development, and abiotic stress responses. To systematically investigate the sugarcane β-1,3-glucanase gene family, 132 glycoside hydrolase (GH) 17 family members were identified in the genomes of the sugarcane wild species Saccharum spontaneum 'Np-X', the tropical species S. officinarum 'LA-Purple', and the Saccharum spp. hybrid cultivar 'R570'. The results of the phylogenetic analysis categorized them into four subfamilies, of which subfamily Ⅳ had the largest proportion of members (102). The members of the sugarcane GH17 gene family contained five conserved motifs and 0-16 introns. The majority of the GH17 genes exhibited a genome-wide replication pattern, with 89.50% originating from S. spontaneum 'Np-X' and S. officinarum 'LA-Purple', while 58.10% of them in the Saccharum spp. hybrid cultivar 'R570' belonged to the discrete replication type. Four major classes of cis-acting elements were identified in the promoters, including the elements related to plant growth, development, and tissue-specific expression (14.21%), light-responsive elements (38.24%), biotic or abiotic stress-responsive elements (9.18%), and hormone-responsive elements (38.37%), which suggested that this gene family was involved in plant growth, development, hormone responses, and stress responses. Transcriptome and quantitative real-time PCR (RT-qPCR) analyses showed that the sugarcane GH17 genes exhibited tissue-specific expression and were differentially expressed under low temperature, drought, and hormone treatments, as well as during the interactions between different sugarcane genotypes and Sporisorium scitamineum, suggesting their potential roles in plant defenses. In addition, some SsGlu genes (SsGlu5, SsGlu20, SsGlu21, SsGlu25, SsGlu28, and SsGlu39) were expected to serve as candidate stress-related genes. This study lays a foundation for further revealing the molecular mechanisms of the stress resistance of sugarcane via β-1,3-glucanase genes.

Multiple myeloma (MM) is a hematological malignancy that poses significant treatment challenges due to its heterogeneity and propensity for relapse and progression. In the last two decades, the therapeutic landscape of MM has changed dramatically, but the disease remains largely incurable, with many patients facing treatment resistance. This review evaluates the current status of MM treatments, emphasizing the limitations of traditional therapies and the emerging role of immunotherapy in improving patient outcomes. It highlights the importance of achieving and maintaining minimal residual disease negativity and a balanced immune response as key treatment goals. Furthermore, it discusses the advancements in immunotherapies that are improving the prospects for patients, particularly those with relapsed or refractory disease. Innovative strategies, such as chimeric antigen receptor T-cell therapy, bispecific antibodies, and bispecific T cell engagers, have shown significant promise by targeting the malignant cells and the bone marrow microenvironment, which are essential for disease persistence and resistance to therapy. Future research should focus on refining MM treatment strategies, including the integration of immunotherapy into earlier treatment lines and the development of predictive biomarkers for personalized treatment approaches, ultimately enhancing patient outcomes.

Objective To investigate the interaction between a novel antimicrobial compound,HL-J6,and penicillin-binding protein 1(PBP1)of Staphylococcus aureus.Methods With MRSA252 genomic DNA as the template and PBP1F and PBP1R as primers,the expression plasmid pET30a-pbp1-39-608 was constructed by amplifying the target gene fragment followed by cloning into the Nde I/Xho I restriction sites of the pET30a vector.Then the obtained plasmids were transformed into Escherichia coli for the expression of PBP1-39-608 protein,and the product was purified by affinity chromatography.The inhibitory effect of HL-J6 on the transpeptidase activity of PBP1-39-608 was measured using peptidoglycan side chain backbone peptide,with thiol ester analog S2d as the substrate.The affinity between HL-J6 and PBP1-39-608 was detected using microscale thermophoresis(MST),and the binding interaction was confirmed by cellular thermal shift assay(CETSA).Molecular docking and dynamics simulation were performed using AutoDock Vina and Desmond software,respectively,to elucidate the binding mode of HL-J6 with the PBP1-39-608 protein and the key amino acid residues involved.Results The recombinant plasmid pET30a-pbp1-39-608 was successfully constructed,and PBP1-39-608 protein was produced after induction and purified,yielding a protein with an approximate molecular mass of 65×103.HL-J6 inhibited the transpeptidase activity of PBP1-39-608 in a time-dependent manner(P<0.001).The dissociation constant Kd of the binding between HL-J6 and PBP1-39-608 was 64.92 μmol/L.Molecular docking results showed that HL-J6 bound to the active pocket of PBP1-39-608 by interacting with key residues such as ILE-348,ASN-370,THR-516 and PHE-423,with a binding score of-8.38 kcal/mol(<-5.00 kcal/mol).Dynamics simulation results indicated that the complex became stable after 50 ns.Conclusion HL-J6 effectively inhibits the transpeptidase activity of Staphylococcus aureus PBP1,and shows stable interaction with the protein.
