In the earliest existing pharmacological monograph in China,Shennong Bencao Jing,there is a record of a parasitic plant known as"desert ginseng"——Cistanche deserticola.It exerts beneficial effects on the function of the heart,kidney,spleen,and lung.As research into its pharmacological properties has progressed,the active components of Cistanche deserticola also have shown promise for treating intestinal disorders.Due to the complex pathological mechanisms of sepsis,which often accompany multiple organ dysfunction,aligns closely with the multi-target pharmacological characteristics of Cistanche deserticola's.Furthermore,because Cistanche deserticola is both edible and medicinal,and exhibits a wide therapeutic window,it has a natural advantage in the clinical transformation and application after drug development.Currently,to expand its medicinal range,a review of the main active components of Cistanche deserticola and their related pharmacological effects is conducted,and combined with the specific characteristics of intestinal injury in sepsis,the potential value of Cistanche deserticola in intestinal barrier protection,microbial coordination,and intestinal motility regulation is further elaborated,providing new ideas and a theoretical basis for the application of Cistanche deserticola in sepsis-induced intestinal injury.

Objective:To analyze the genetic characteristics of hemagglutinin（HA）and neuraminidase（NA）of influenza A（H1N1）pdm09 viruses in Kunming during the 2022-2023 influenza season.Methods:A total of 15 strains of A（H1N1）pdm09 influenza virus isolated from sentinel hospital surveillance and from outbreaks from April 2022 to March 2023 in Kunming were chosen for sequencing. The genetic analysis，which included sequence alignment，homology analysis，construction of phylogenetic tree and amino-acid mutations analysis，was carried out using MAFFT version 7，MegAlign and MEGA 11.Results:Fourteen strains isolated during the 2022-2023 influenza season in Kunming belong to clade 6B.1A.5a.2a，and A/Kunming/284/2023 belonged to clade 6B.1A.5a.2a.1. They all diverged from the northern hemisphere vaccine strain A/Wisconsin/588/2019 in clade 6B.1A.5a.2 recommended by WHO during the 2022-2023 influenza season. Comparing with the HA of the vaccine strain：A186T and Q189E，which might cause the reduction of vaccine protection，were identified in Sb of 14 strains；P137S，K142R in Ca and A186T，Q189E in Sb were identified in A/Kunming/284/2023 and two strains isolated from Thailand. The four mutations at tow antigenic sites identified immune escape at the molecular level. Q189E in the 190-helix and E224A in the 220-loop，which might change the pathogenicity of A（H1N1）pdm09 viruses，were identified in 15 strains. Comparing with NA of the vaccine strain：S200N in 14 strains and S339L in 1 strain were identified in antigenic sites. The two mutations might reduce the protection of antibodies induced by NA.Conclusion:Strengthening influenza surveillance and timely detecting new variants in Kunming contributes to preventing the importation of foreign strains and issuing early warnings for influenza outbreaks.

OBJECTIVE: To explore the implementation effect of hour-1 bundle for sepsis patients based on crisis resource management (CRM) system. METHODS: A historical control study was conducted. The hour-1 bundle for sepsis based on CRM was used to train 24 nurses in the emergency department from October 2022 to March 2023. Clinical data of sepsis patients admitted to the emergency department of the First People's Hospital of Zunyi from April 2022 to September 2023 were collected. The patients were divided into three groups based on different stages of CRM system construction: control group (before construction, from April to September in 2022), improvement group (during construction, from October 2022 to March 2023) and observation group (after construction, from April to September in 2023). The baseline data, implementation rate of hour-1 bundle [including blood culture, antibiotic usage, blood lactic acid (Lac) detection, fluid resuscitation, hypertensors usage], identification and diagnosis time, and prognosis parameters [including correction rate of hypoxemia, intensive care unit (ICU) occupancy rate, and 28-day survival rate]. Sepsis cognition survey and non-technical skill (NTS) evaluation of nurses in emergency department were conducted before and after training. RESULTS: Finally 43 cases were enrolled in the control group, improvement group and observation group, respectively. There was no statistically significant difference in baseline data including the gender, age, primary site, heart rate, systolic blood pressure, acute physiology and chronic health evaluation II (APACHE II) score, sequential organ failure assessment (SOFA) score, mechanical ventilation ratio among the three groups with comparability. With the gradual improvement of the CRM system, the implementation rate of 1-hour bundle was gradually increased, and the implementation rate in the control group, improvement group and observation group were 65.12% (28/43), 74.42% (32/43) and 88.37% (38/43), respectively, with statistically significant difference (P < 0.05). It was mainly reflected in the completion rate of blood culture, antibiotic usage rate, Lac detection rate and hypertensors usage rate within 1 hour, which were significantly higher in the observation group than those in the control group [completion rate of blood culture: 90.70% (39/43) vs. 62.79% (27/43), antibiotic usage rate: 88.37% (38/43) vs. 60.47% (26/43), Lac detection rate: 93.02% (40/43) vs. 72.09% (31/43), hypertensors usage rate: 88.37% (38/43) vs. 60.47% (26/43), all P < 0.05]. The fluid resuscitation rates within 1 hour in the three groups were all over 90%, with no statistically significant difference among the three groups. The recognition and diagnosis time in the observation group was significantly shorter than that in the control group and the improvement group (hours: 0.41±0.15 vs. 0.61±0.21, 0.51±0.18, both P < 0.05), the correction rate of hypoxemia and 28-day survival rate were significantly higher than those in the control group [correction rate of hypoxemia: 95.35% (41/43) vs. 74.42% (32/43), 28-day survival rate: 83.72% (36/43) vs. 60.47% (26/43), both P < 0.05], and ICU occupancy rate was significantly lower than that in the control group [72.09% (31/43) vs. 93.02% (40/43), P < 0.05]. After training in the CRM system, the score of the sepsis awareness survey questionnaire for emergency department nurses was significantly increased as compared with before training (60.42±5.29 vs. 44.17±9.21, P < 0.01), and NTS also showed significant improvement. CONCLUSION CRM plays a significant role in promoting the implementation of sepsis hour-1 bundle, which can improve the implementation rate of hour-1 bundle and NTS of medical staff, effectively improve patients' hypoxemia, reduce patients' ICU occupancy rate and 28-day risk of death.

Objective:To summarize the clinical phenotype and genetic characteristics of deficiency in ELF4 gene X-linked (DEX).Methods:A case series study was conducted to retrospectively analyze the clinical data and genetic testing results of 2 cases of DEX treated at Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and the First Hospital of Jilin University from January 2023 to April 2024. And literature up to April 2024 was searched from the PubMed database, as well as CNKI and Wanfang databases, using keywords such as "ELF4 deficiency" "deficiency in ELF4, X-linked""ELF4 gene". The main clinical manifestations and genotypes of DEX were summarized.Results:Both patients were male, with onset ages of 3 months and 3 years, respectively. Both patients presented with recurrent oral ulcers and abdominal pain. And the laboratory examination showed a significant increase in inflammatory markers. Intestinal examinations showed multiple intestinal ulcers, and both patients developed intestinal fistulas. Whole exome sequencing found ELF4 c.799C>T, p Arg267Trp and ELF4 c. 248-7G>A, both maternal variants. Based on clinical and genetic results, DEX were diagnosed. In terms of treatment, both patients underwent surgical treatment during the acute phase of the disease and received anti-tumor necrosis factor α therapy, but recurrent gastrointestinal symptoms were still observed in Patient 1, while the clinical effect in Patient 2 was still acceptable. However, the inflammatory markers in both patients were not normal even after treatment. Literature review found 18 patients including 2 patients in this study, reported in 5 English articles and no Chinese reports. Thirteen patients had disease onset age before 5. The main clinical manifestations were fever (12/17), oral ulcers (14/18), abdominal pain (8/18), diarrhea (6/18), perianal ulcers (5/17), ileum ulcers (6/16), colon ulcers (7/16), skin involvement (7/17) and recurrent infections (7/18); laboratory examinations found increased erythrocyte sedimentation rate (13/15) as well as C-reactive protein (9/9), and anemia (13/15); in terms of immunological function, there is a decrease in natural killer cells (9/15) as well as a decrease in class switching memory B cells (8/9). The main types of gene variantions were missense variantions (6/18), nonsense variantions (4/18) or frameshift variantions (3/18).Conclusions:DEX should be considered when an early-onset male patient manifested with recurrent fever, oral ulcers or mucosal ulcers, with elevated inflammatory markers, with or without recurrent infection. It is recommended to perform lymphocyte subsets analysis, gastrointestinal endoscopy and genetic testing to support the diagnosis.

With advancements in radiology,endoscopic techniques,surgical treatments,cell biology and molecular biology,the un-derstanding of temporomandibular disorders(TMD)has increased.The temporomandibular joint(TMJ)is a complex structure comprising both soft and hard tissues.Within the TMJ,the temporomandibular disc is a soft tissue structure that connects the mandible to the skull,providing cushioning and stability during joint movement.Different imaging techniques have their own advantages and limi-tations in the diagnosis and treatment of TMD.Therefore,using image registration technology to assess the condition and position of the articular disc provides new research perspectives for evaluating TMD,which may contribute to the diagnosis and treatment.This article reviews the latest advancements in TMJ imaging,explores the applications of various image registration techniques,particularly in the context of TMD diagnosis and treatment,and discusses future prospects.Combining the research results of some scholars at home and a-broad with the author’s clinical experience,the article aims to provide valuable insights for clinicians.

Background: As social media continue to grow as popular and convenient tools for acquiring and disseminating health information, the need to investigate its utilization by laypersons encountering common medical issues becomes increasingly essential. Objectives: This study aimed to analyze the content posted in Facebook groups for Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency and how these engage the members of the group. Methods: This study employed an inductive content analysis of user-posted content in both public and private Facebook groups catering specifically to G6PD deficiency. The G6PD Facebook groups with 10 or more posts within the past 12 months were selected for this study. Data were harvested from posts and comments using ExportComment. Results: A total of 46 G6PD-related Facebook groups were identified. Of which, 19 were public and 27 were private groups, with an average membership of 5000-6000 accounts. After eligibility based on criteria and authorization for private groups, 3 public and 3 private groups were included, with the majority of these groups focused on sharing information. Five main themes of posted content were identified: diagnosis, management, beliefs, psychosocial factors, and medical requirements. “Diagnosis”-related posts referred to conversations about the causes and symptoms of G6PD, “management” referred to medication or diet, “beliefs” involved traditional or lay perceptions, “psychosocial factors” referred to posts that disclosed how psychosocial factors influenced G6PD deficiency practices, and “medical requirements” referred to documentation regarding the condition. The bulk of these posts used three strategies for communication: information-requesting, self-disclosure, and promotion of products/services. Information requests were the most common. Conclusion The results of the study showed opportunities and challenges in health education on G6PD, especially in evaluating the credibility and accuracy of the information given and received. Looking at the content and manner of communicating information noted, the newborn screening program may improve its advocacy and education campaign, and may develop targeted educational materials and effective dissemination strategies that could clarify, explain, or refute information and beliefs mostly shared on these platforms.
