Xiaoji Yinzi is one of the classic prescriptions for treating urinary diseases， originated from the Yan's Prescriptions to Aid the Living （Yan Shi Ji Sheng Fang） written by YAN Yonghe in the Song dynasty. Xiaoji Yinzi is composed of Rehmanniae Radix， Cirsii Herba， Talcum， Akebiae Caulis， Typhae Pollen， Nelumbinis Rhizomatis Nodus， Lophatheri Herba， Angelicae Sinensis Radix， Gardeniae Fructus， and Glycyrrhizae Radix et Rhizoma and has the effects of cooling blood and stopping bleeding， draining water and relieving stranguria. The medical experts of later generations have inherited the original prescription recorded in the Yan's Prescriptions to Aid the Living， while dispute has emerged during the inheritance of this prescription. In this study， the method of bibliometrics was employed to review and analyze the ancient documents and modern clinical studies involving Xiaoji Yinzi. The results showed that Xiaoji Yinzi has two dosage forms： powder and decoction. According to the measurement system in the Song Dynasty， the modern doses of hers in Xiaoji Yinzi were transformed. In the prepration of Xiaoji Yinzi powder， 149.2 g of Rehmanniae Radix and 20.65 g each of Cirsii Herba， Talcum， Akebiae Caulis， stir-fried Typhae Pollen， Nelumbinis Rhizomatis Nodus， Lophatheri Herba， wine-processed Angelicae Sinensis Radix， stir-fried Gardeniae Fructus， and stir-fried Glycyrrhizae Radix et Rhizoma are grounded into fine powder with the particle size of 4-10 meshes and a decocted with 450 mL water to reach a volume of 240 mL. After removal of the residue， the decoction was taken warm before meals， 3 times a day （i.e.， 7.77 g Rehmanniae Radix and 0.97 g each of the other herbs each time）. In the preparation of Xiaoji Yinzi decoction， 20.65 g each of the above 10 herbs are used， with stir-fried Typhae Pollen， wine-processed Angelica Sinensis Radix， stir-fired Gardeniae Fructus， stir-fired Glycyrrhizae Radix et Rhizoma， and raw materials of other herbs. Xiaoji Yinzi is specialized in treating hematuresis and blood stranguria due to heat accumulation in lower energizer， which causes injury of the blood collaterals of gallbladder and dysfunction of Qi transformation. In modern clinical practice， Xiaoji Yinzi is specifically used for treating urinary diseases and can be expanded to treat diseases of the cardiovascular system and other systems according to pathogenesis. The comprehensive research on the key information could provide a scientific reference for the future development of Xiaoji Yinzi.

Objective To analyze the distribution of occupational hazard factors (OHFs) in key enterprises in Foshan City. Methods A total of 373 enterprises from 11 key industries in Foshan City in 2022 were selected as the research subjects using the purposive sampling method. Monitoring data of OHFs in workplaces were obtained and analyzed from the "Workplace Occupational Hazards Monitoring Information System" under "China Disease Prevention and Control Information System". Results Among the 373 enterprises, small and micro-sized enterprises, and large and medium-sized enterprises accounted for 85.5% and 14.5% respectively. A total of 24 137 sampling points in the workplaces were monitored for OHFs, with the national standard compliance rate of 92.1%. Among different OHFs, the compliance rates ranked from highest to lowest were chemical agents, dust, and noise (98.0% vs 89.3% vs 52.0%, P<0.01). A total of 63 131 workers were employed in 373 enterprises, among whom 29 753 were exposed to OHFs, yielding an overall exposure rate of 47.1%. Exposure rates of OHFs by enterprise scale, from highest to lowest, were micro-sized, small-sized, medium-sized, and large-sized enterprises (69.2% vs 52.7% vs 47.3% vs 39.0%, P<0.01). The proportion of workers participated in occupational medical examination was 85.1%, with re-examination proportion of 62.5% and the abnormality detection rate of 2.1%. Conclusion In key enterprises in Foshan City, the risk of noise exposure is relatively high, and the exposure rate of OHFs is highest in micro-sized enterprises. The occupational health supervision and management department needs to strengthen the governance of noise hazards in a targeted manner and urge enterprises (especially micro-sized enterprises) to fulfill their primary responsibilities in occupational disease prevention and control.

Mayaro fever is a mosquito-borne viral infectious disease caused by Mayaro virus (MAYV). The main clinical symptoms are sudden onset of high fever triad, arthralgia and maculopapular rash. MAYV outbreaks occur more frequently in the Americas Region, particularly within tropical forests in Brazil. However, in recent years, virus circulation has been spreading to the Switzerland and Netherlands in Europe, which may invade urban areas and cause epidemics across the region. Consequently, this work focuses on the epidemiological characteristics and research progress of MAYV prevention and control, including biological characteristics, epidemiology, transmission vectors, prevention measures and treatment of this virus.

Objective To investigate the safety and efficacy of novel bioabsorbable vascular scaffold(BVS)in the treatment of patients with complex coronary artery disease.Methods This was a retrospective,matched,single-center observational study.45 patients with coronary atherosclerotic cardiopathy received BVS treatment in the cardiovascular medicine department Department of the Affiliated Hospital of Guangdong Medical University from June 2020 to June 2021(BVS),and 45 patients treated with drug-eluting stents(DES)group were selected according to matching study requirements during the same period.Baseline,surgical,and follow-up data were compared between the two groups to evaluate safety and efficacy.The main measures of safety were:surgical time,intraoperative adverse events,etc.,and the end point of efficacy was target lesion failure(TLF),including cardiac death,target vessel myocardial infarction,and ischa-driven target lesion revascularization.Results A total of 90 patients were enrolled in this study,all of whom were followed up for at least 3 years.There were 20 cases of bifurcation lesions and 25 cases of diffuse long lesions in the two groups,and 50 cases of imaging were reviewed among the 90 patients.The proportion of stable coronary heart disease,history of diabetes,history of hypertension,history of smoking,pre-dilated balloon pressure and postoperative diastolic blood pressure in BVS group was higher than that in DES group,and the proportion of family history was lower than that in DES group(all P＜0.05).There were no statistically significant differences in the rates of cardiac death,target vessel myocardial infarction,and ischemia-driven revascularization of target lesions between the two groups(all P＞0.05).Binary Logistic regression model analysis showed that the diameter stenosis ratio of target lesions was an independent risk factor for intrastent restenosis(OR 2.786,95％CI 1.096-7.081,P=0.031).Conclusions Compared with traditional DES,BVS implantation has consistent safety and efficacy in the treatment of complex coronary artery disease within 3 years.The diameter stenosis ratio of target lesions was an independent risk factor for intrastent restenosis.

Objective:To compare the prognostic value of two predictive models based on C-reactive protein(CRP)and albumin(ALB),namely the CRP to ALB ratio(CAR)and the Glasgow prognostic score(GPS),in newly diagnosed patients with diffuse large B-cell lymphoma(DLBCL).Methods:The data of newly diagnosed DLBCL patients admitted to our center from May 2014 to January 2022 were reviewed.A total of 111 patients who completed at least 4 cycles of R-CHOP or R-CHOP-like chemotherapy with detailed clinical,laboratory data and follow-up information were included.The receiver operating characteristic(ROC)curve was performed to evaluate the predictive value of pre-treatment CAR on disease progression and survival.Furthermore,the association between CAR and baseline clinical,laboratory characteristics of patients was evaluated,and progression-free survival(PFS)and overall survival(OS)were compared between different CAR and GPS subgroups.Finally,the univariate and multivariate COX propor-tional hazard regression models were used to analyze the factors affecting disease outcomes.Results:ROC curve showed that the area under the curve(AUC)of CAR predicting PFS and OS in DLBCL patients was 0.687(P=0.002)and 0.695(P=0.005),respectively,with the optimal cut-off value of 0.11 for both predicting PFS and OS.Compared with the lower CAR(＜0.11)group,the higher CAR(≥0.11)group had more clinical risk factors,including age＞60 years(P=0.025),ECOG score ≥2(P=0.004),Lugano stage Ⅲ-Ⅳ(P＜0.001),non-germinal center B-cell-like(non-GCB)subtype(P=0.035),elevated lactate dehydrogenase(LDH)(P＜0.001),extranodal involved site＞1(P=0.004)and IPI score＞2(P＜0.001).The interim response evaluation of patients showed that the overall response rate(ORR)and complete response rate(CRR)in the lower CAR group were both significantly better than those in the higher CAR group(ORR:96.9％vs 80.0％,P=0.035;CRR:63.6％vs 32.5％,P=0.008).With a median follow-up of 24 months,patients with lower CAR had significantly longer median PFS and OS than those with higher CAR(median PFS:not reached vs 67 months,P=0.0026;median OS:not reached vs 67 months,P=0.002),while there was no statistical difference in PFS(P=0.11)and OS(P=0.11)in patients with GPS of 0,1,and 2.Multivariate Cox regression analysis indicated that only sex(male)and IPI score＞2 were independent risk factors for both PFS and OS.Conclusion:CAR is significantly correlated with disease progression and survival in DLBCL patients;And compared with GPS,CAR has more advantages in predicting disease outcomes in DLBCL patients.

Objective:To compare the efficacy and safety of flumatinib (FM)and imatinib (IM)as first-line treatment in newly-diagnosed patients with chronic myeloid leukemia in chronic phase (CML-CP ) in real world. Methods:A total of 84 newly-diagnosed CP-CML patients in our center from December 2019 to December 2022 were retrospectively analyzed.Among them,32 cases received FM as first-line treatment,and 52 cases received IM. Molecular response (MR),disease progression,survival and incidence of adverse events (AEs)were compared between the two groups.Results:At 3 months of treatment,the incidences of early molecular response (EMR ),MR2.0 and MR3.0 were 96.7％,70.0％ and 20.0％ in FM group,respectively,which were significantly higher than 77.1％,29. 2％ and 0 in IM group (all P<0.05 ).At 6,9 and 12 months of treatment,the incidences of major molecular response (MMR)in FM group were 68.2％,85.7％ and 90.0％,respectively,which were significantly higher than 22.9％,34.0％ and 51.1％ in IM group (all P<0.01).The median time to achieve MMR in FM group was 6(6-9)months,which was significantly shorter than 18(12-22)months in IM group (P<0.001 ).The 3-year progression-free survival rate and 3-year event-free survival rate in FM group were 100％ and 68.8％,respectively,while in IM group were 98.1％ and 55.8％.There were no significant differences between the two groups (P>0.05). The incidence of grade 3-4 hematologic AEs in FM group was 21 .9％,which was slightly lower than 25.0％ in IM group,but the difference was not significant (P>0.05 ).Conclusion:In real clinical practice,FM as first-line treatment achieves MMR earlier than IM,and exhibits good safety profile in newly-diagnosed CML-CP patients,which potentially leads to improved long-term survival and treatment-free remission.

The risk of patient infection inevitably increases with the use of more invasive operations in the intensive care unit(ICU),including endotracheal tubes,indwelling catheter,central venous catheter,etc.The preparation of antibacterial coatings is an effective way to solve such infections.Antibacterial coatings,such as silver nanoparticles coating,zinc oxide coating,methyl blue coating,antimicrobial peptides coating,and nano titanium dioxide(TiO2)coating,can effectively prevent the formation of biofilms on the surface of implant materials.As a photocatalyst,TiO2 has excellent photocatalytic and antibacterial activity,non-toxic and biocompatible properties,strong physical and chemical stability,and long-lasting antibacterial properties,which makes it high value for research.This review summarizes the bactericidal mechanism and clinical application of TiO2,offering valuable reference for clinical practice.

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.
