Huangqintang， with its accurate efficacy， is a classic formula specialized in treating dysentery recommended and promoted by medical experts from successive generations， and it was included in the Catalogue of Ancient Classic Prescriptions （the Second Batch， Han Chinese medicine prescriptions） published by the National Administration of Traditional Chinses Medicine （TCM） in 2023. The method of bibliometrics was applied in this study to conduct textual research on the classic formula Huangqintang and provide a literature reference for the development of modern preparations of Huangqintang. A total of 2 026 pieces of ancient literature were searched with "Huangqintang" as the key word， and 23 pieces of effective data were selected， involving 15 ancient TCM books. The historic evolution， composition， dosage， origin， processing methods， preparation and decocting methods， efficiency， and application of Huangqintang were carefully reviewed. The results showed that Huangqintang was first recorded in the Treatise on Febrile Diseases written by ZHANG Zhongjing. It has the effect of clearing heat， stopping dysentery， regulating the middle， and downbearing counterflow and has become one of the classic formulas widely used in clinical practice. Because of its accurate efficacy， medical experts from later generations have modified it from its original composition. Though many prescriptions have different names， it is the manifestation of physicians' inheritance and development of the thought of ZHANG Zhongjing. Ancient literature showed this prescription had wide indications yet centered on digestive system diseases such as dysentery and abdominal pain. Modern applications of Huangqintang involve digestive， respiratory， ophthalmology and otolaryngology， gynecological， skin， musculoskeletal system， and connective tissue， and this prescription has great potential in treating ulcerative colitis， diarrhea， acute enteritis， and damp-heat dysentery. Through a systematic textual excavation and review of the ancient literature about Huangqintang， the paper has confirmed its key information， so as to provide a scientific basis for the clinical application and new drug development of classic formulas.

Objective:To explore the health behavior of middle-aged and young stroke patients and analyze its influencing factors.Methods:From April to July 2023, convenience sampling was used to select 172 middle-aged and young stroke patients admitted to the First Affiliated Hospital of Naval Medical University as the research subject. A survey was conducted using the General Information Questionnaire, Health Behavior Scale for Stroke Patients, Health Belief Scale, and Multidimensional Scale of Perceived Social Support. Spearman correlation was used to analyze the correlation between health behavior, social support, and health beliefs among middle-aged and young stroke patients. Multiple linear regression was used to analysis the influencing factors of health behavior among middle-aged and young stroke patients. A total of 172 questionnaires were distributed, and 8 questionnaires with missing items and short response times were excluded, and 164 valid questionnaires were collected, with a valid response rate of 95.34%.Results:Among 164 middle-aged and young stroke patients, the total score of the Health Behavior Scale for Stroke Patients was 64.50 (57.00, 80.75), and the average score of the items was 2.58 (2.28, 3.23). Multiple linear regression analysis showed that factors affecting the health behavior of middle-aged and young stroke patients were whether it was the first onset, the time required to reach nearby medical institution, health belief, and social support ( P<0.05) . Conclusions:The health behavior of middle-aged and young stroke patients is above the medium level. In the process of intervening in the health behavior of middle-aged and young stroke patients, medical and nursing staff should pay attention to patients with recurrent stroke and poor access to medical services, while also improving patients' health belief and social support to promote patients' health behavior and reduce stroke recurrence.

Objective:To explore the mediating effect of coping style on disease perception and pre-hospital delayed behavioral intention in patients with acute ischemic stroke.Methods:This study was a cross-sectional study. From February to July 2023, convenience sampling was used to select 205 patients with acute ischemic stroke admitted to the First Affiliated Hospital of Naval Medical University as the study subject. The survey was conducted using the General Information Questionnaire, Stroke Pre-Hospital Delay Behavior Intention, Brief Illness Perception Questionnaire, and Simplified Coping Style Questionnaire.Results:205 questionnaires were filled out, 195 valid questionnaires, and the validity rate of the questionnaire was 95.1%. The Stroke Pre-Hospital Delay Behavior Intention score of patients with acute ischemic stroke was (63.61±16.12). Pre-hospital delayed behavioral intention in patients with acute ischemic stroke was positively correlated with disease perception and negative coping ( r=0.360, 0.266; P<0.01), and negatively correlated with positive coping ( r=-0.279, P<0.01). The mediating effects of positive and negative coping on disease perception and pre-hospital delayed behavioral intention in ischemic stroke patients were 0.111 and 0.097, respectively, accounting for 26.89% and 23.49% of the total effect. Conclusions:There is a partial mediating effect of coping strategies between disease perception and pre-hospital delayed behavioral intention in ischemic stroke patients. In the process of stroke management, medical and nursing staff can reduce pre-hospital delayed behavioral intentions by improving disease cognition and coping style.

To investigate the effects of ORF9 gene of porcine circovirus type 2(PCV2)on PK-15,eu-karyotic expression plasmid was constructed and transfected into PK-15 cells,and the effects of overexpression of ORF9 on proliferation,apoptosis and immunization of PK-15 cells were exam-ined by flow cytometry and qRT-PCR.The results showed that ORF9 gene overexpression signifi-cantly up-regulated the expression levels of the ER stress marker gene GRP78,increased the num-ber of S phase cells,accelerated cell cycle progression,increased the apoptosis rate of PK-15 cells,up-regulated the expression levels of apoptosis-related genes caspase-3,caspase-8,caspase-9,p53 and Bax(P＜0.01),down-regulated the expression levels of apoptosis-related genes Bcl-2,up-reg-ulated the expression levels of immune-related genes 1L-8,IL-10,NF-κB and TNF-α(P＜0.01),and down-regulated the expression levels of immune-related genes IL-2,IFN-β and IL-12(P＜0.01).The above results indicate that ORF9 gene may promote the proliferation and apoptosis of PK-15 cells and play a role in the escape process of PK-15 cells.

In order to understand the genomic characteristics and genetic variation and strain type of infectious bursal disease virus(IBDV)isolate GZGY2022,which caused the death of chickens in Guizhou farm,primers were designed to amplify the whole genome of the isolate,and genetic evo-lution and strain type analysis were performed after cloning and sequencing.The results showed that the A and B segments of IBDV genome were 3 260,2 827 bp,respectively,encoding VP2-VP5 and VP1 genes.The nucleotide sequence homology between the A and B segments of this strain and the VvIBDV were 96.2％-98.7％and 87.7％-98.9％,respectively,which is the highest with NN1172 strain,83.1％-94.7％and 90.1％-91.0％with other strains.The results of genetic evolution and strain type study showed that IBDV strains can be divided into 6 branches according to antigen and virulence,and the A and B segments of the strain were clustered in the evolutionary branch of VvIBDV,and the strain was A3B3 genotype according to the new genotype classification method.The results of amino acid sequence analysis showed that there were 3 and 7 unique amino acid site variations in the A and B segments of the strain,respectively,and 13 unique characteristic amino acid sites in the coding region of the full-length genome were consistent with VvIBDV.The VP2 sequence of segment A has 19 characteristic amino acid identical with VvIBDV,among which hyper variable regions 222A,242I,253Q,256I,279D,284A,294I and 299S were characteristic ami-no acid sites of the VvIBDV,and the heptapeptide region sequence SWSASGS was consistent with the virulent strain.The VP1 sequence of segment B has 10 characteristic amino acid identical with VvIBDV,among which 61I,145T and 287A were the characteristic amino acid sites of the VvIB-DV.In addition,the nucleotide sequence GGTGCC of 777-782 did not form the restriction endo-nuclease site of Kpn Ⅰ,and combined with the triplet site 145/146/147(TEG),the segment B was consistent with the NN1172 strain,showed that its virulence was slightly weaker than that of the B2 strain of VvIBDV.The results of recombination analysis showed that there were no breaks and recombination sites in the sequence of the strain,and no recombination event occurred.In summa-ry,this study found that GZGY2022 strain belonged to the A3B3 genotype non-recombinant VvIB-DV strain,and its special amino acid sites were consistent with the molecular characteristics of VvIBDV.This study lays the foundation for further exploring the genomic characteristics and path-ogenicity of VvIBDV.

Objective:To comprehensively understand the basic situation of critical care medicine in Xinjiang Production and Construction Corps in order to promote the standardization, specialization, and systematization of quality control in critical care medicine.Methods:A survey was conducted from January 1, 2019, to December 31, 2021, using a questionnaire to investigate the human resources and basic allocation of comprehensive intensive care medicine departments in Xinjiang Production and Construction Corps division level hospitals and surrounding second-class hospitals. The survey content includes: basic situation of medical units, intensive care unit (ICU) basic information, ICU personnel situation, ICU equipment configuration situation, ICU performance situation, etc. The survey questionnaire was distributed in March 2022, with dedicated ICU attending physicians or above designated by each ICU as the contact person for the survey.Results:Sixteen questionnaires were distributed and returned, all of which were included from 16 comprehensive intensive care medicine departments in the Corps and surrounding areas, including 5 second class first class hospitals and 11 third class first class hospitals. There were 196 beds in 16 ICU units, and the ICU bed ratio (1.99% overall, 1.77% in third class first class hospitals) was lower than the 2%-8% stipulated in the Guidelines for the Construction and Management of Critical Care Medicine (Trial) issued by the National Health Commission. Only ICU beds in second class first class hospitals accounted for 2.65%, meeting this standard. The comprehensive ICU doctor-bed ratio in 16 hospitals was 0.55∶1, third class first class hospitals was 0.60∶1, and second class first class hospitals was 0.44∶1, compared with 0.8∶1 stipulated in the ministerial guidelines, there was a certain gap. Among the 108 doctors in 16 ICUs, only four have a master's degree or above. Associate senior and above professional and technical titles accounted for 27.78%, less than one third. Among the 334 nursing staff, there were no personnel with a master's degree or above, and only 10 personnel with associate senior or above professional and technical titles. From 2019 to 2021, there was 1 new master's degree personnel, 2 new senior professional and technical personnel, and 12 deputy senior professional and technical personnel. It indicating that the proportion of highly educated and experienced physicians and nurses were lower, team building lags behind, talent introduction were lower, and highly educated talents were scarce. The statistical analysis results of the absolute growth of core technology showed that the growth of core technology was slow, the progressiveness was insufficient, and the professional technical ability was insufficient. Conclusions:The construction of critical care majors and talent echelons in the Xinjiang Production and Construction Corps region is lagging behind, the overall professional level of the discipline is not high, and there is a lack of specialized personnel. Further improvement is needed in talent cultivation, technical development and training, medical quality management, and other aspects to ensure medical quality and safety.

Objective:To evaluate the efficacy of neonatal resuscitation simulation exercise for perinatal medical personnel.Methods:From August 2020 to July 2021, perinatal medical personnel receiving simulated training of neonatal resuscitation in our hospital were prospectively enrolled. The professional backgrounds of the trainees were collected and their performances on both knowledge skills and behavioral skills were scored. The knowledge skills included pre-resuscitation preparation, initial resuscitation, positive pressure ventilation, tracheal intubation, chest compression and umbilical vein catheterization. The behavioral skills included situational awareness, problem solving, resource utilization, communication and leadership. SPSS 26.0 was used for data analysis.Results:Among the 200 participants, 127(63.5%) were neonatal/pediatric doctors and nurses, 65(32.5%) were obstetricians and midwives, 8(4.0%) were anesthesiologists and the ratio of doctors to nurses was 1.74∶1. The score of knowledge skills was (19.52±2.92) at the beginning of the simulation exercise and (27.02±2.72) at the end. The scores on preparation before resuscitation, initial resuscitation and positive pressure ventilation were significantly improved ( P<0.05). The score of behavioral skills was (16.60±2.34) at the beginning and (20.58±1.77) at the end. The scores of resource utilization, communication and leadership were significantly improved ( P<0.05). Conclusions:The simulation exercise provides multidisciplinary teamwork training for perinatal medical personnel, may significantly improve neonatal resuscitation skills and is worth promoting.

Objective:To analyze the comorbidity status and influencing factors of hypertension, diabetes, and dyslipidemia among middle-aged and elderly Chinese adults and to provide support for the "co-management of three diseases".Methods:Using the relevant information collected from the National Chronic Disease and Risk Factor Surveillance in China in 2018, 134 950 permanent residents aged ≥45 years were selected as the research objects. After being weighed, the prevalence and comorbidity of hypertension, diabetes, and dyslipidemia in residents with different groups were compared; a multivariate logistic regression model was used to explore the influencing factors of comorbidity of the "three diseases".Results:The prevalence of hypertension, diabetes, and dyslipidemia among middle-aged and elderly Chinese adults were 46.0% (95% CI:45.1%-47.0%), 19.5% (95% CI:18.7%-20.2%), 43.3% (95% CI:42.3%-44.4%), respectively. The comorbidity rates of hypertension and diabetes, hypertension and dyslipidemia, and diabetes and dyslipidemia were 12.3% (95% CI:11.7%-12.8%), 22.8% (95% CI:22.1%-23.4%),11.6% (95% CI:11.1%-12.0%), respectively; the comorbidity rate of hypertension, diabetes, and dyslipidemia was 7.6% (95% CI: 7.2%-8.0%). These comorbidity rates increased with age and BMI, which was more significant in the urban areas than rural areas and more outstanding in North and Northeast China ( P<0.05). The comorbidity rate of hypertension, diabetes, and higher cholesterol was 1.9% (95% CI:1.7%-2.1%). The comorbidity rate of hypertension, diabetes, and higher low-density lipoprotein was 1.6% (95% CI:1.4%-1.7%), which was higher in women than in men ( P<0.05). Multivariate logistic regression results showed that male, age, city, overweight/obesity, excessive drinking, physical inactivity, daily sedentary behavior time ≥5 hours, and sleep duration <7 hours were risk factors for the comorbidity of the "three diseases". Conclusions:The comorbidity of hypertension, diabetes, and dyslipidemia, is common among middle-aged and elderly adults in China; comprehensive prevention and control of risk factors and "co-management of three diseases" are critical measures for health promotion in middle-aged and elderly populations.
