This study analyzed the characteristics of 118 738 seasonal migrants who were aged 65 and under management by the Health Statistics Center of Hainan Health Commission.Our study revealed that approximately 51.6％of elderly seasonal migrants were male,with around 75.2％aged below 75 years.Elderly seasonal migrants originating from the Northeast region constituted roughly 36.3％of the total,and the majority of them settled in Haikou,Chengmai and Dongfang(each representing over 10％of the total).Of the nine prevalent health conditions surveyed,about 27.6％of the elderly seasonal migrants suffered at least one condition.Haikou,Wanning,Qionghai,and Dongfang received more than 3 000 elderly seasonal migrants with health issues.Considering the availability of healthcare resources,there exists a negative correlation between the distribution of elderly seasonal migrants and the hospitalization service load of doctors in various destination areas.This study recommends Hainan Province further improving the seasonal migrants dynamic survey system,scientifically arranging healthcare resources and services,and systematically enhancing the health service experience of the seasonal migrants.

Sepsis-induced coagulopathy(SIC),a critical and potentially lethal condition arising from sepsis,results in endothelial damage and significant coagulation dysregulation,making it a major factor contributing to mortality among sepsis patients.Early diagnosis and treatment of SIC are expected to improve the prognosis of sepsis patients.In 2019,the International Society on Thrombosis and Hemostasis(ISTH)issued the first guidelines for the diagnosis and treatment of SIC,but there are no corresponding protocols in China.Therefore,Chinese Society of Thrombosis,Hemostasis and Critical Care,Chinese Medicine Education Association,and Chinese People's Liberation Army Professional Committee of Critical Care Medicine jointly formulated the"Chinese Expert Consensus on the Diagnosis and Treatment of Sepsis-induced Coagulopathy(2024 edition)."This consensus includes 5 parts:pathogenesis,classification,laboratory approaches,diagnosis and treatment,with a total of 14 evidence-based recommendations to guide clinical practice.

italic>Tussilago farfara L. is a perennial herb of Tussilago genus in the Compositae family. Its dried buds and leaves have good biological activities and have a long history of medicinal use in China and Europe. In this paper, we investigated the whole chloroplast genome characteristics, sequence duplication, structural variation and phylogeny of the Tussilago farfara L. After sequencing the Tussilago farfara L. chloroplast genome using Illumination technology, the complete Tussilago farfara L. chloroplast genome was further obtained by assembly and annotation, followed by a series of inverted repeat-large single copy/small single copy region contraction and expansion analysis, genome sequence variation, etc. The sequences of 13 homologous plants downloaded from NCBI were used to construct a neighbor-joining phylogenetic tree. The results showed that the total GC content of the chloroplast genome was 37.4% and the length was 150 300 bp; 125 genes were annotated, including 82 protein-coding genes, 35 tRNAs and 8 rRNAs; 148 (simple sequence repeats, SSR) loci were detected, and the relative synonymous codon usage showed that 31 codons out of 64 codons had a usage of >1. In the phylogenetic analysis, the chloroplast genomes of the seven species of Asteraceae, including the Yulin Tussilago farfara L., were highly conserved, and the sequence variation of the (large single-copy, LSC) and (small single-copy, SSC) regions was higher than that of the (inverted repeat, IR) region. This is in general agreement with the reported phylogeny of Yulin Tussilago farfara L. In this study, we obtained a high quality chloroplast genome and analyzed its genome characteristics, codon preference, SSR characteristics, SC/IR boundary, sequence variation and phylogeny, which can provide a basis for species identification, genetic diversity analysis and resource development of this medicinal plant.

【Objective】 To investigate the expressions of P53 and Ki-67 in prostate cancer (PCa)and to explore their correlation with the clinicopathological characteristics. 【Methods】 The expressions of P53 and Ki-67 in 90 PCa patients were detected with immunohistochemistry. Patients’ age, preoperative prostate-specific antigen (PSA) level, postoperative Gleason score, pathological stage, and invasion of neurovascular cancer embolus of all patients were recorded. The relationship of P53 expression with the above indexes was evaluated. 【Results】 The positive rates of P53 and Ki-67 were 27.8% (25/90) and 46.7% (42/90), respectively. The positive rate of P53 in pT2 and pT3-T4 stage groups were 19.7% (13/66) and 50.0% (12/24) (P=0.005), and the positive rate of Ki-67 were 36.4% (24/66) and 75.0% (18/24) (P=0.001), respectively. The positive rate of Ki-67 in Gleason score ≤6, ≤7 and ≥8 groups were 30.4%, 53.8% and 66.7%, respectively, with statistical difference. Positive expression of P53 was related to Ki-67 expression, but not to patients’ age, preoperative PSA level, postoperative Gleason score and nerve and invasion of neurovascular cancer embolus. 【Conclusion】 P53 expression is related to tumor stage and Ki-67, while Ki-67 expression is associated with tumor stage ang grade.

Objective: To establish the HPLC fingerprint of wild and cultivated Notholirion bulbuliferum,and recognize them according to the chemical pattern, in the expectation of providing the basis for the quality control and domestication cultivation of N. bulbuliferum of origins. Method: Twenty samples of wild and cultivated N. bulbuliferum collected from different origins were detected by HPLC, and a common mode of fingerprint was established. The Similarity Evaluation System for Chromatographic Fingerprint of TCM (2012A edition) was used to evaluate the similarity of the samples. The differences among the samples were identified by chemical pattern recognition methods, including principal component analysis (PCA),cluster analysis (HCA) and partial least squares discriminate analysis (PLS-DA). Result: The HPLC fingerprint of N. bulbuliferum was obtained,and 26 common peaks were found in the chromatograph. Similarities of all samples were over 0.9,PCA,and HCA and PLS-DA results demonstrated obvious distinctions between wild and cultivated N. bulbuliferum. Eight constituents,such as pcoumaric acid were identified as biomarkers,representing major differences between the two varieties. Conclusion: The HPLC chromatogram of N. bulbuliferum developed in this paper has strong characteristics and repeatability. After being combined with the pattern recognition mode, it can be used as an effective method for evaluating the quality of N. bulbuliferum and distinguishing wild and cultivated N. bulbuliferum,and provide a reference for the quality control and domestication introduction of N. bulbuliferum.

"Jinchai Shihu" were called Jinchai and recoded in "Taishang Zhouhou Yujingfang" of Tang Dynasty, which first clearly documented the name of Shihu in complex Dendrobium medicines and were condiered as superior medicinal articles. Morphological features are one of the naming principles for Chinese medicines. In this paper, botanical origin plants under the names of "Jinchai" and "Jinchai Shihu" were investigated. Based on documents from the local Chronicles and historical accounts, the Chinese characters of Jinchai have the distinctive features of gold color and two hair clasps. Moreover, the hair clasps are usually cylindrical in shape with uniform thickness in middle and upper part, and tapers off to the foot. And its bottom part style is simple and head part is complex. Thus we speculated the herbal "Jinchai" and "Jinchai Shihu" should have similar morphologic features as Chinese characters of Jinchai, including golden color and hairpin shape of stems without braches, short and solid sterm. After comparing the dried vegetative morphology of 10 common medicinal Dendrobium species, we suggested that of Dendrobium flexicaule matches well with the morphological features from historical herbal records.

Rubia cordifolia L. has been used as a traditional Chinese medicine for several centuries. In recent years, the resources of wild Rubia cordifolia have been declined sharply due to increased utilization and rising price. Therefore, it is of great urgency to evaluate and protect resources of wild plant of Rubia cordifolia. In our study, sixty-four individuals that represent eight wild populations of Rubia cordifolia L. were analyzed by Start Codon Targeted Polymorphism (SCoT) molecular markers. Genetic distance was calculated by POPGENE 3.2 software, cluster analysis was generated by NTSYS 2.10 software based on UPGMA method and Mantel Test was used to analysis the relationship between the genetic distances and geographical distance among the wild populations. The results showed a high genetic diversity of wild populations of Rubia cordifolia L. in Shaanxi province. A total of 182 bands were produced by 14 primers, among which 163 bands were polymorphic bands, and the percentage of polymorphic bands was 89.56%. The average value of Nei's genetic diversity index (H) was 0.293 6, Shannon's information index (I) was 0.444 6, genetic differentiation coefficient (Gst) was 0.555 3, and the gene flow (Nm) was 0.440 8, the wild populations were ranked by genetic diversity:AK > YL > SL > BJ > TC > YA > WN > XY. Mantel Test analysis demonstrated that the significant correlation was found between the genetic distances and geographical distances (r=0.776 4, P<0.05). There is a significant correlation between geographical and genetic distances. This study provides a theoretical basis for the protection and development of the resources of wild Rubia cordifolia L. germplasms.

Objective:To study the influencing factors of serum high-sensitivity cardiac troponin T(hs-cTnT)levels in chronic kidney disease(CKD)patients.Methods:The clinical data of CKD patients treated at a hospital were collected.Fasting blood samples were collected to measure the level of hs-cTnT.Single factor analysis,univariate linear regression analysis and multiple linear regression analysis were carried out to screen the influencing factors of hs-cTnT.Objective:The level of hs-cTnT was detected in 324 CKD patients,and the median level was 0.012 μg/L.In early-stage CKD patients,Cys C,UACR and left ventricular mass index(LVMI)were positively correlated with hs-cTnT level(P<0.05),and the hs-cTnT level increased significantly in CKD patients with hypertension or diabetes.The estimated glomerular filtration rate(eGFR)was negatively correlated with the hs-cTnT level(P=0.003).Conclusions:The elevated levels of hs-cTnT in CKD patients are associated with a variety of factors,so clinicians should make a comprehensive assessment of the causes of elevated hs-cTnT level.

BACKGROUNDThe European Society of Urogenital Radiology has built the Prostate Imaging Reporting and Data System (PI-RADS) for standardizing the diagnosis of prostate cancer (PCa). This study evaluated the PI-RADS diagnosis method in patients with prostate-specific antigen (PSA) <20 ng/ml.

METHODSA total of 133 patients with PSA <20 ng/ml were prospectively recruited. T2-weighted (T2WI) and diffusion-weighted (DWI) magnetic resonance images of the prostate were acquired before a 12-core transrectal prostate biopsy. Each patient's peripheral zone was divided into six regions on the images; each region corresponded to two of the 12 biopsy cores. T2WI, DWI, and T2WI + DWI scores were computed according to PI-RADS. The diagnostic accuracy of the PI-RADS score was evaluated using histopathology of prostate biopsies as the reference standard.

RESULTSPCa was histologically diagnosed in 169 (21.2%) regions. Increased PI-RADS score correlated positively with increased cancer detection rate. The cancer detection rate for scores 1 to 5 was 2.8%, 15.0%, 34.6%, 52.6%, and 88.9%, respectively, using T2WI and 12.0%, 20.2%, 48.0%, 85.7%, and 93.3%, respectively, using DWI. For T2WI + DWI, the cancer detection rate was 1.5% (score 2), 13.5% (scores 3-4), 41.3% (scores 5-6), 75.9% (scores 7-8), and 92.3% (scores 9-10). The area under the curve for cancer detection was 0.700 (T2WI), 0.735 (DWI) and 0.749 (T2WI + DWI). The sensitivity and specificity were 53.8% and 89.2%, respectively, when using scores 5-6 as the cutoff value for T2WI + DWI.

CONCLUSIONSThe PI-RADS score correlates with the PCa detection rate in patients with PSA <20 ng/ml. The summed score of T2WI + DWI has the highest accuracy in detection of PCa. However, the sensitivity should be further improved.

INTRODUCTIONRecent studies examining the association of Toll-like receptor 3 (TLR3) gene polymorphisms with the risk of developing various types of cancer have reported conflicting results. Clarifying this association could advance our knowledge of the influence of TLR3 single nucleotide polymorphisms (SNPs) on cancer risk.

METHODSWe systematically reviewed studies that focused on a collection of 12 SNPs located in the TLR3 gene and the details by which these SNPs influenced cancer risk. Additionally, 14 case-control studies comprising a total of 7997 cases of cancer and 8699 controls were included in a meta-analysis of 4 highly studied SNPs (rs3775290, rs3775291, rs3775292, and rs5743312).

RESULTSThe variant TLR3 genotype rs5743312 (C9948T, intron 3, C>T) was significantly associated with an increased cancer risk as compared with the wild-type allele (odds ratio [OR]=1.11, 95% confidence interval [CI]=1.00-1.24, P=0.047). No such association was observed with other TLR3 SNPs. In the stratified analysis, the rs3775290 (C13766T, C>T) variant genotype was found to be significantly associated with an increased cancer risk in Asian populations. Additionally, the rs3775291 (G13909A, G>A) variant genotype was significantly associated with an increased cancer risk in Asians, subgroup with hospital-based controls, and subgroup with a small sample size.

CONCLUSIONAfter data integration, our findings suggest that the TLR3 rs5743312 polymorphism may contribute to an increased cancer risk.
