Objective To make an epidemiological investigation on traditional Chinese medicine(TCM)dampness syndrome manifestations in the population at risk of cerebrovascular diseases in Guangdong area.Methods A cross-sectional study was conducted to analyze the clinical data related to the risk of cerebrovascular diseases in 330 Guangdong permanent residents.The diagnosis of dampness syndrome,quantitative scoring of dampness syndrome and rating of the risk of stroke were performed for the investigation of the distribution pattern of dampness syndrome and its influencing factors.Results(1)A total of 306(92.73%)study subjects were diagnosed as dampness syndrome.The percentage of dampness syndrome in the risk group was 93.82%(258/275),which was slightly higher than that of the healthy group(48/55,87.27%),but the difference was not statistically significant(χ2 = 2.91,P = 0.112).The quantitative score of dampness syndrome in the risk group was higher than that of the healthy group,and the difference was statistically significance(Z =-2.24,P = 0.025).(2)Among the study subjects at risk of cerebrovascular disease,evaluation time(χ2 = 26.11,P = 0.001),stroke risk grading(χ2= 8.85,P = 0.031),and history of stroke or transient ischemic attack(TIA)(χ2 = 9.28,P = 0.015)were the factors influencing the grading of dampness syndrome in the population at risk of cerebrovascular disease.Conclusion Dampness syndrome is the common TCM syndrome in the population of Guangdong area.The manifestations of dampness syndrome are more obvious in the population with risk factors of cerebrovascular disease,especially in the population at high risk of stroke,and in the population with a history of stroke or TIA.The assessment and intervention of dampness syndrome should be taken into account for future project of stroke prevention in Guangdong.

Since the World Health Organization(WHO)officially announced COVID-19 as a global pandemic in 2020,114 countries or regions in the world have been affected to varying degrees.The arrival of the post-epidemic era requires countries to take new epidemic prevention and control measures to deal with the problems and challenges that may arise in the future.In order to help China consolidate its epidemic prevention achievements over the years and gain a larger development window in the post-epidemic era,this study explored the changes in the global epidemic situation and the major national prevention and control policies in different countries,summarized the development and changes of China's epidemic prevention and control policies,and proposed new family-centered precision prevention and control measures that adapt to China's national conditions.

Objective To explore the application of regional cerebral oxygen saturation(rSO2)-bispectral index(BIS)monitoring anesthesia in children undergoing surgery for supracondylar fractures of the humerus.Methods A total of 60 children with supracondylar fractures of the humerus undergoing surgery in Department of Orthopedi,Jiangxi Provincial Children's Hospital were chosen and randomly number table method segmented into control group and observation group from January 2020 to December 2022,30 cases in each group.After anesthesia,children in observation group were carried out with rSO2-BIS monitoring,while children in control group were given routine anesthesia management.Results The dosage of propofol and long chain fat emulsion/remifentanil injection in observation group were significantly lower than those in control group(P＜0.05),while there was no difference in heart rate,blood oxygen saturation and mean arterial pressure at various time points during awakening(P＞0.05);The recovery rate of postoperative analgesics of observation group was lower than that of control group,and the extubation time of observation group was shorter than that of control group(P＜0.05);The incidence of postoperative adverse reactions and behaviors in observation group were lower than those in control group(P＜0.001).The dosage of propofol and long chain fat emulsion/remifentanil injection,as the independent risk factors inducing the occurrence of postoperative adverse reactions and adverse behaviors were proved by multivariate analysis.rSO2-BIS monitoring is a key factor in reducing postoperative adverse behaviors and reactions in pediatric patients(P＜0.05).Conclusion The use of rSO2-BIS monitoring during surgery for supracondylar fractures of the humerus in children can reduce the incidence rate of postoperative adverse behaviors and adverse reactions,thereby improving postoperative efficacy.

Objective: To analyze the prevalence and related factors of pediatric flexible flatfoot (PFF) among 7-8 year old children in Changzhou, so as to provide a feasible basis for the prevention and treatment of PFF. Methods: From December 2023 to February 2024, a total of 1 685 children aged 7-8 from 10 primary schools in Changzhou were selected by stratified cluster random sampling method, and screened for PFF by using a foot optical assessment recording device. Information including sex, body mass index (BMI), diet, exercise and shoe wearing habits were collected. The valgus angle of the hindfoot was measured on the body surface by using an orthopedic measuring ruler in the standing position. Pain levels were evaluated by using visual analogue score (VAS) for children with flatfoot syndrome. Multivariate Logistic analysis was used to analyze related factors of PFF. Results: The overall detection rate of PFF was 27.4%, and there was a significant difference in the detection rate of PFF between boys and girls, with 30.3% and 24.1% respectively ( χ 2=7.96, P < 0.01 ). Most cases of PFF were mild flatfoot (60.8%) and bilateral ( 60.4% ). Approximately 13.2% of children with PFF had flatfoot syndrome, with a mean VAS of (2.86±0.73). About 56.1% of children with PFF had a normal valgus angle of the hindfoot. Sex, high BMI and preference for shoe last with front upturned shoe shape were positively correlated with the detection of PFF ( OR= 1.74, 1.54, 1.13, P <0.05). After stratified by sex, regular exercise in boys and age in girls were negatively correlated with the detection of PFF ( OR=0.40, 0.64, P <0.05). Conclusions The detection rate of PFF in 7-8 year old children is high. Additionally, PFF combined with flatfoot syndrome or valgus hindfoot is relatively rare and is likely to be underestimated, which emphasizes the importance of early detection and intervention for PFF.

Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

Objective To explore the mechanism of inhibiting a disintegrin and metalloprotease 8(ADAM8)expression on inflammatory damage in alcoholic liver fibrosis mice.Methods C57BL/6N male mice were randomly divided into the control group,the alcohol group,and the plasmid group,with 10 mice in each group.The alcohol group and plasmid group were fed alcohol liquid feed on a daily basis and gavaged with 31.5％ethanol(5 g/kg,twice a week);The control group was fed control liquid feed and gavaged with an equal amount of saline.The plasmid group was injected with the effective plasmid ADAM8-small guide RNA3(sgRNA3)(2 g/kg,twice a week)to inhibit the ADAM8 gene through the tail vein,while the alcohol group was injected with an equal amount of saline through the tail vein for 8 weeks to induce alcoholic liver fibrosis.After eyeball blood collection,the mice were euthanized,and their liver was separated and extracted.Sirius red and HE staining were employed to assess liver fibrosis and damage;Western blotting was used to determine the expression of α-smooth muscle actin(α-SMA),collagen Ⅰ,and ADAM8;Real-time PCR was used to measure the expression of ADAM8 mRNA;the expression of ADAM8,transforming growth factor-β1(TGF-β1),p-p38 MAPK and heat shock protein 27(HSP27)proteins was detected by Western blotting,Biochemical detection were used to detect alanine aminotransferase(ALT)and aspartate transaminase(AST)activity;tumor necrosis factor-α(TNF-α)and interleukin-1(IL-1)levels were determined by ELISA.Results The alcohol group had increased collagen fiber volume fraction,liver injury scores,and positive area rates of α-SMA and collagen Ⅰ;the expression of ADAM8 mRNA and ADAM8 protein increased,with increased positive area rate;and levels of AST,ALT,TNF-α,and IL-1 were higher,along with increased expression of TGF-β1,p-p38MAPK,and HSP27 proteins.In the plasmid group,the collagen fiber volume fraction,liver injury scores,and positive area rates of α-SMA and collagen Ⅰ was reduced;the expression of ADAM8 mRNA and protein was reduced,with decreased positive area rate,and levels of AST,ALT,TNF-α,and IL-1 were lower,along with reduced expression of TGF-β1,p-p38MAPK,and HSP27 proteins.Conclusion Downregulation of ADAM8 expression can alleviate inflammatory damage by inhibiting TGF-β1/p38MAPK signaling pathway to improve alcoholic liver fibrosis in mice.

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.

Objective:To investigate the effect of progression of disease within 24 months(POD24)on overall survival(OS)in patients with mantle cell lymphoma(MCL),and compare the clinical characteristics between POD24 and non-POD24 patients.Methods:A retrospective analysis was performed on 50 MCL patients with treatment indications and regular treatment who were admitted to the Affiliated Hospital of Xuzhou Medical University from January 2010 to August 2020.According to the occurrence of POD24,the patients were grouped for prognostic evaluation and clinical characteristics comparison.Results:Univariate Cox regression analysis showed that POD24,PLT,albumin,MIPI score,ECOG PS score,LDH were the factors influencing OS in newly diagnosed MCL patients(all P＜0.05).The results of multivariate Cox regression analysis showed that POD24[HR=16.797(95％CI:3.671-76.861),P＜0.001],albumin＜40 g/L[HR=3.238(95％CI:1.095-9.572),P=0.034]and ECOG PS score≥2[HR=4.005(95％CI:1.033-15.521),P=0.045]were independent risk factors influencing OS in MCL patients.The incidence of PLT＜100 × 109/L(33.3％vs 5.9％,P=0.033)and ECOG PS score≥2(45.5％vs 5.9％,P=0.040)were significantly higher in POD24 patients than those in non-POD24 patients.Conclusion:POD24 is an independent poor prognostic factor affecting the OS of MCL patients,and the patients with PLT＜100 × 109/L and ECOG PS score ≥2 at diagnosis have a higher probability of POD24.

Objective:To investigate the effect of endothelial activation and stress index(EASIX)on the prognosis of patients with angioimmunoblastic T-cell lymphoma(AITL)and peripheral T-cell lymphoma,not otherwise specified(PTCL-NOS),and to compare the clinical characteristics of patients in the low EASIX and high EASIX groups.Methods:The clinical data of 59 newly diagnosed AITL and PTCL-NOS patients admitted to the Affiliated Hospital of Xuzhou Medical University from January 2010 to September 2021 were retrospectively analyzed.The optimal cut-off value of EASIX was determined by receiver operating characteristic(ROC)curve;The chi-square test was used to analyze the correlation between EASIX and clinical features of patients with AITL and PTCL-NOS;The Kaplan-Meier survival curve was used to analyze the overall survival(OS)and progression-free survival(PFS)of the patients;Univariate and multivariate analyses were performed by using Cox proportional hazards model.Results:The optimal cut-off value of EASIX was 0.95,based on which the patients were divided into a low EASIX(＜0.95)group and a high EASIX(≥ 0.95)group.Compared with the low EASIX group,the high EASIX group had a higher proportion of patients with advanced Ann Arbor stage,higher risk according to IPI,elevated LDH,hypoproteinemia,anemia,B symptoms,extranodal involvement,and bone marrow involvement.Survival analysis showed that the OS and PFS of patients in the high EASIX group were significantly shorter than those in the lower EASIX group(P＜0.001).The multivariate analysis showed that EASIX was an independent risk factor for OS[HR=7.217(95％CI:1.959-26.587),P=0.003]and PFS[HR=2.718(95％CI:1.032-7.161),P=0.043]of PTCL patients.Conclusion:High EASIX in newly diagnosed patients with AITL and PTCL-NOS suggests a poor prognosis,and high EASIX is a risk factor affecting prognosis of the patients.

Objective:To investigate the correlation between nutritional status and quality of life in inpatients with nasopharyngeal carcinoma and to analyze the factors affecting nutritional status,so as to provide evidence for clinical nutritional support treatment.Methods:In this study,we retrospectively collected data from patients with nasopharyngeal carcinoma who met the inclusion and exclusion criteria in the Head and Neck Oncology Department of Zunyi Medical University Affiliated Hospital from 2014 to 2019.The NRS 2002 scale was used for nutritional risk screening,the PG-SGA scale for nutritional status assessment and the EORTCQLQ-C30 V3.0 scale for quality of life assessment.To further explore the correlation between nutritional status and quality of life,as well as the factors affecting nutritional status.Results:A total of 216 patients were collected,including 168 male(77.78%);average age(50.5±10.58)years;26.85%were at nutritional risk(NRS 2002 score≥3);28.70%were moderate malnutrition(PG-SGA score 4-8),and 23.15%were severe malnutrition(PG-SGA score≥9).There were significant differences in several physical examinations(such as body weight,body mass index,muscle circumference at the midpoint of the upper arm,etc.)and blood biochemical indexes(such as prealbumin,neutrophils,urea nitrogen,etc.)of patients with different nutritional status were differed between groups(P<0.05).Univariate analysis showed that age≥65 years was a risk factor for the development of severe malnutrition(OR:3.429,95%CI:1.467 to 8.014,P=0.004),whereas a high level of education(senior high school and above)was a protective factor(OR:0.027,95%CI:0.011 to 0.064,P=0.000).The poorer the nutritional status of nasopharyngeal carcinoma patients,the lower the quality of life.Conclusion:Nasopharyngeal carcinoma patients have a high incidence of malnutrition;the poorer the nutritional status of the patient,the lower the quality of life;routine nutritional diagnosis and treatment of nasopharyngeal carcinoma patients after admission to the hospital is recommended to improve clinical outcomes.
