Objective:To conduct a scoping review on symptom cluster of hematopoietic stem cell transplantation (HSCT) patients, aiming to provide reference for improving postoperative symptom management in HSCT patients.Methods:The study on postoperative symptom clusters in HSCT patients was searched in PubMed, Web of Science, CINAHL, Embase, Cochrane Library, China National Knowledge Infrastructure, Chinese Biomedical Database, VIP, and WanFang Data. The search period was from database establishment to July 17, 2023.Results:A total of 10 articles were included, and 9 symptom clusters were extracted. The top three symptom clusters in terms of frequency were fatigue related, gastrointestinal related, and psychological symptom clusters. The influencing factors of symptom cluster mainly included chronic graft-versus-host disease, transplant type, conditioning regimen, gender, depression level and so on. The heterogeneity of HSCT patient symptom cluster assessment tools was relatively high.Conclusions:The dynamic changes of postoperative symptom clusters in HSCT patients are influenced by multiple factors, and specific assessment tools still need to be developed.

AIM To study the effects of Liangxue Heying Formula on vascular inflammatory injury in a rat model of thromboangiitis obliterans(TAO).METHODS The rats were randomly divided into the sham operation group,the model group and the low,medium and high dose Liangxue Heying Formula groups(2.25,4.5,9 g/kg).With the rat TAO model successfully established by injection of 0.1 mL sodium laurate(10 mg/mL)into the femoral artery of hind limbs,corresponding doses of drugs by gavage were administered upon the rats.Subsequently,the rats had their morphological changes of the affected limbs observed and assessed;their changes of blood flow in hind limbs scanned by laser Doppler flowmetry;their plasma levels of TNF-α,IL-6,ICAM-1 and VCAM-1 detected by ELISA;their histopathological changes of femoral artery and vein observed by HE staining;and their protein expressions of TNF-α,IL-6,JAK2,p-JAK2,STAT3,p-STAT3,ICAM-1 and VCAM-1 in femoral artery detected by Western blot.RESULTS Compared with the sham operation group,the model group displayed increased morphological score of the affected limb(P＜0.01);decreased blood perfusion ratio of the affected side/healthy side(P＜0.01);increased plasma levels of TNF-α,IL-6,ICAM-1 and VCAM-1(P＜0.01);more existence of thrombotic infiltration containing a larger number of inflammatory cells in femoral artery and femoral vein tissue,and increased protein expressions of TNF-α,IL-6,p-JAK2,p-STAT3,ICAM-1 and VCAM-1 in femoral artery(P＜0.01).Compared with the model group,the medium and high dose Liangxue Heying Formula groups demonstrated decreased morphological score of the affected limb(P＜0.01);increased blood perfusion ratio of the affected side/healthy side(P＜0.01);reduced infiltration of thrombus and inflammatory cells in femoral artery and femoral vein tissue,and decreased protein expressions of IL-6 and p-STAT3 in femoral artery tissue(P＜0.01).All Liangxue Heying Formula groups shared decreased plasma levels of TNF-α,IL-6,ICAM-1 and VCAM-1(P＜0.05,P＜0.01);and reduced protein expressions of TNF-α,ICAM-1,VCAM-1 and p-JAK2 in femoral artery(P＜0.01).CONCLUSION Liangxue Heying Formula can improve the systemic inflammatory state of TAO rats by inhibiting the activation of endothelial cells and reducing vascular inflammatory injury possibly due to the mechanism associated with the regulation of the JAK2/STAT3 signaling pathway.

Objective To analyze risk factors and pathogenic characteristics of intestinal colonization of carbape-nem-resistant Enterobacterales(CRE)in patients from intensive care unit(ICU).Methods A total of 392 ICU pa-tients who underwent intestinal CRE screening in a tertiary hospital in Changzhou from March to December,2023 were divided into the colonization group(n=42)and the non-colonization group(n=350)according to the screening results.Clinical data of patients,including age,gender,underlying diseases,malignant tumors,radiotherapy,chemotherapy,infection before the last screening,antimicrobial use,and invasive procedures were collected for the analysis on risk factors and pathogenicity.Results Among 42 patients with positive CRE screening results,44 CRE strains were detected,mainly Klebsiella pneumoniae(65.91％),followed by Escherichia coli(15.91％)and En-terobacter cloacae(13.64％).The average time from admission in ICU to positive screening results of intestinal CRE in the colonization group was 14 days.Long term use of carbapenem antibiotics(OR=1.47,95％CI:1.31-1.65),mechanical ventilation(OR=1.14,95％CI:1.06-1.22),and Enterobacterales infection(OR=10.10,95％CI:3.28-32.09)were independent risk factors for intestinal CRE colonization.Patients who received carbap-enem antibiotics for ≥15 days(x2=167.52,P＜0.001)and those who received mechanical ventilation for ≥15 days(x2=101.03,P＜0.001)had higher risks for intestinal CRE colonization.Conclusion In clinical practice,it is necessary to improve pathogen detection,treat Enterobacterales infection timely,choose carbapenem antibiotics carefully,shorten treatment course,actively evaluate indications for mechanical ventilation,and wean off ventilator timely.

Objective To compare CT manifestations of pneumocystis jirovecii pneumonia(PCP)and cytomegalovirus pneumonia(CMVP)after allogeneic hematopoietic stem cell transplantation(allo-HSCT).Methods Totally 21 PCP patients(PCP group)and 26 CMVP patients(CMVP group)after allo-HSCT were retrospectively enrolled,and CT findings were compared between groups.Results Significant differences of distribution patterns of ground glass opacity(GGO)and nodule lesions,lung cysts,the time of condition reached most severe,the proportion of cases with lesions absorption more than 50％ within 30 days,of cases with lesions completely absorbed and the first total severity score(TSS)of GGO were found between groups(all P＜0.05).Conclusion CT manifestations of PCP and CMVP after allo-HSCT were somehow similar,but GGO distributed widerly,with more lung cysts and better prognosis in the former,while GGO distrubuted relatively limitted with diffuse nodules and poor prognosis in the latter.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Malocclusion,identified by the World Health Organization(WHO)as one of three major oral diseases,profoundly impacts the dental-maxillofacial functions,facial esthetics,and long-term development of～260 million children in China.Beyond its physical manifestations,malocclusion also significantly influences the psycho-social well-being of these children.Timely intervention in malocclusion can foster an environment conducive to dental-maxillofacial development and substantially decrease the incidence of malocclusion or reduce the severity and complexity of malocclusion in the permanent dentition,by mitigating the negative impact of abnormal environmental influences on the growth.Early orthodontic treatment encompasses accurate identification and treatment of dental and maxillofacial morphological and functional abnormalities during various stages of dental-maxillofacial development,ranging from fetal stages to the early permanent dentition phase.From an economic and societal standpoint,the urgency for effective early orthodontic treatments for malocclusions in childhood cannot be overstated,underlining its profound practical and social importance.This consensus paper discusses the characteristics and the detrimental effects of malocclusion in children,emphasizing critical need for early treatment.It elaborates on corresponding core principles and fundamental approaches in early orthodontics,proposing comprehensive guidance for preventive and interceptive orthodontic treatment,serving as a reference for clinicians engaged in early orthodontic treatment.

Objective To investigate the effect of caloric restriction(CR)on myocardial ischemia/reperfusion injury(MI/RI)in mice and its mechanism.Methods C57 mice were randomly divided into normal diet group(AL group,free feeding)and CR group(diet decreased by 10% every 2 weeks)for 8 weeks and monitored for weight changes.Each group was divided into sham operation group and MI/RI group,total 4 groups,AL + Sham group,AL + I/R group,CR + Sham group and CR + I/R group).The left anterior descending coronary artery was ligated for 30 minutes and then reperfused for 24 hours in mice of MI/RI group and mice in Sham group were only threaded but not ligated.The mice were determined for myocardial ischemia and infarct size by Evans blue/TTC staining,observed for the pathology of myocardium by HE staining,determined for the activities of lactate dehydrogenase(LDH),superoxide dismutase(SOD)and the contents of creatine kinase-MB(CK-MB)and malondialdehvde(MDA)in myocardium by the corresponding kits,determined for serum levels of IL-1β and IL-18 by ELISA and detected for the expression of pyroptosis-associated proteins in myocardium by Western blot.Results After 8weeks,the weights of mice in CR group[(24.54 ± 0.41)g]were significantly lower than those in AL group[(31.46 ±0.25)g](t = 14.34,P<0.05).Compared with those in AL + I/R group,the area of myocardial ischemia in CR + I/R group showed no significant difference(t = 0.783 0,P>0.05),while the area of myocardial infarction decreased significantly(t = 7.250,P<0.01);The myocardial arrangement was relatively neat,and the degree of pathological changes was obviously reduced;LDH activity,CK-MB and MDA contents decreased significantly(t = 4.331,2.875 and 5.343 respectively,each P<0.05),while SOD activity increased significantly(t = 4.211,P<0.05);Serum levels of IL-1β and IL-18 decreased significantly(t = 3.375 and 4.266 respectively,each P<0.05);The expression levels of nod-like receptor protein 3(NLRP3),gasdermin D(GSDMD),apoptosis-associated speckle-like protein(ASC)and caspase-1 significantly decreased(t = 3.412,3.420,3.480 and 2.585 respectively,each P<0.05).Conclusion CR alleviated MI/RI in mice,and its mechanism was related to the inhibition of cardiac pyroptosis.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.

Objective: To understand the current situation of vaccination services for adults in China, explore how to establish a stable and efficient vaccination service system for adults, and provide reference for formulating corresponding policies. Methods: The vaccination information systems of nine provinces in China were used to obtain information on urban and rural vaccination of influenza vaccine, 23-valent pneumococcal polysaccharide vaccine (PPV23), and human papillomavirus vaccine (HPV) from 2019 to 2021. The indicator, vaccination rate/full vaccination rate, was used for statistical description. Results: The vaccination rate/full vaccination rate of the three vaccines in eastern China was generally higher than that in central and western China. The vaccination rate/full vaccination rate in urban areas was generally higher than that in rural areas. From 2019 to 2021, the vaccination rates of influenza vaccine among people aged 60 years and above in urban and rural areas were 2.96%, 6.29%, 6.14% and 1.29%, 2.58%, 2.94%, respectively. The vaccination rates of the PPV23 among people aged 60 years and above in urban and rural areas increased year by year, with rates of 0.38%, 1.05%, 1.15% and 0.14%, 0.49%, 0.59%, respectively. From 2019 to 2021, the HPV coverage of female adults aged 27-45 years in urban and rural areas increased year by year, with rates of 0.46%, 0.93%, 1.88% and 0.17%, 0.40%, 1.08%, respectively. Conclusion: The vaccination rates of influenza vaccine,PPV23 vaccine and HPV vaccine for adults in China are relatively low, with higher rates in the eastern region than in the central and western regions, and higher rates in urban areas than in rural areas. It is recommended to formulate corresponding health and economic policies and explore a suitable vaccination service system for adults in China to improve vaccination rates.
