This paper summarized professor WU Mianhua's experience in the treatment of tumors using Hehuanhua （Flos Albiziae）. He believes that the occurrence and development of tumors are closely related to emotions， and thereafter proposed the concept of "masses usually due to constraint， and should be treated by regulating the spirit".Hehuanhua is a light and aromatic flower that enters the heart， liver and spleen meridians， and is good at relieving constraint and regulating the spirit， harmonizing the center with aroma， which can be used to treat all kinds of tumor-related complications. Hehuanmi is flower buds， picked before the flowers fully blooms， have the effect of clearing and lightening upward， opening up the heart and mind， and unblocking liver qi. Commonly used formulas include self-made Ningxin Anmian Decoction （宁心安眠汤） to treat tumor-related insomnia， self-made Aitongxiao Formula （癌痛消方） to treat tumor-related pain， self-made Erhua Jieyu Formula （二花解郁方） to treat tumor-associated depression， and self-made Shugan Tiaohe Decoction （疏肝调和汤） to deal with peri-menopausal state after the treatment of tumors. Hehuanhua is an inflorescence， which captures the aromatic essence and has the function of removing the filth and turbidity， and can wake up the spleen and harmonize the stomach； therefore， it is often used in self-made Tiaomu Hezhong Decoction （调木和中汤） to treat chemotherapy-related digestive tract adverse reactions or combined with rose flowers to treat chemotherapy-induced oral ulcers.

BACKGROUND: Postoperative pulmonary complications (PPCs) are major adverse events in neurosurgical patients. This study aimed to develop and validate machine learning models predicting PPCs after neurosurgery. METHODS: PPCs were defined according to the European Perioperative Clinical Outcome standards as occurring within 7 postoperative days. Data of cases meeting inclusion/exclusion criteria were extracted from the anesthesia information management system to create three datasets: The development (data of Huashan Hospital, Fudan University from 2018 to 2020), temporal validation (data of Huashan Hospital, Fudan University in 2021) and external validation (data of other three hospitals in 2023) datasets. Machine learning models of six algorithms were trained using either 35 retrievable and plausible features or the 11 features selected by Lasso regression. Temporal validation was conducted for all models and the 11-feature models were also externally validated. Independent risk factors were identified and feature importance in top models was analyzed. RESULTS: PPCs occurred in 712 of 7533 (9.5%), 258 of 2824 (9.1%), and 207 of 2300 (9.0%) patients in the development, temporal validation and external validation datasets, respectively. During cross-validation training, all models except Bayes demonstrated good discrimination with an area under the receiver operating characteristic curve (AUC) of 0.840. In temporal validation of full-feature models, deep neural network (DNN) performed the best with an AUC of 0.835 (95% confidence interval [CI]: 0.805-0.858) and a Brier score of 0.069, followed by Logistic regression (LR), random forest and XGBoost. The 11-feature models performed comparable to full-feature models with very close but statistically significantly lower AUCs, with the top models of DNN and LR in temporal and external validations. An 11-feature nomogram was drawn based on the LR algorithm and it outperformed the minimally modified Assess respiratory RIsk in Surgical patients in CATalonia (ARISCAT) and Laparoscopic Surgery Video Educational Guidelines (LAS VEGAS) scores with a higher AUC (LR: 0.824, ARISCAT: 0.672, LAS: 0.663). Independent risk factors based on multivariate LR mostly overlapped with Lasso-selected features, but lacked consistency with the important features using the Shapley additive explanation (SHAP) method of the LR model. CONCLUSIONS: The developed models, especially the DNN model and the nomogram, had good discrimination and calibration, and could be used for predicting PPCs in neurosurgical patients. The establishment of machine learning models and the ascertainment of risk factors might assist clinical decision support for improving surgical outcomes.

OBJECTIVE: To investigate the effects of combined platelet-rich plasma (PRP) and arterial supercharging technique on the survival rate and functional restoration of cross-body region skin flaps in rabbits. METHODS: Twelve healthy 6-month-old New Zealand White rabbits were randomly assigned to 4 groups ( n=3): sham group, PRP group, anastomosis group, and combined treatment group. An axial skin flap with an area of 12 cm×6 cm on the inner side of the hind limbs of all animals were prepared, with the saphenous artery as the main blood supply. Following the ligation of both the proximal and distal ends of the saphenous artery across all groups, the sham group received no further intervention, the PRP group was subjected to PRP injection, the anastomosis group underwent in situ end-to-end anastomosis of the distal saphenous artery, and the combined treatment group received both in situ distal saphenous artery anastomosis and PRP administration. Flap survival was evaluated and recorded on postoperative days 1, 3, and 7, with survival rates calculated accordingly. On day 7, flap tissue samples were harvested for HE staining to assess basal tissue morphology. Additionally, immunohistochemical staining was conducted to detect the expression of α-smooth muscle actin (α-SMA), vascular endothelial growth factor (VEGF), and CD31 in the flap tissues. RESULTS: At postoperative day 1, no significant difference in flap survival rates were observed among the 4 groups ( P>0.05). At day 3, the PRP group showed no significant difference compared to the sham group ( P>0.05); however, both the anastomosis and combined treatment groups exhibited significantly higher survival rates than the sham group ( P<0.05), the combined treatment group further demonstrated superior survival rates compared to both the PRP and anastomosis groups ( P<0.05). At day 7, the combined treatment group maintained significantly higher survival rates than all other groups ( P<0.05), while both the PRP and anastomosis groups exceeded the sham group ( P<0.05). HE staining at day 7 revealed persistent inflammatory cell infiltration, sheet-like erythrocyte deposition, and disordered collagen fibers in the sham group. The PRP group showed nascent microvessel formation and early collagen reorganization, whereas the anastomosis group displayed mature microvasculature with resolved interstitial edema. The combined treatment group exhibited differentiated microvessels with densely packed collagen bundles. Immunohistochemical analysis at day 7 demonstrated significantly larger relative area percentages of α-SMA, VEGF, and CD31 positive cells in the combined treatment group compared to all other groups ( P<0.05). Both the PRP and anastomosis groups also showed significantly higher values than the sham group ( P<0.05). CONCLUSION The combination of PRP and arterial supercharging techniques significantly enhances flap healing, potentially through mechanisms involving augmented angiogenesis and improved blood supply.

Objective Five chloroplast(cp)genomes from members of genus Polygonatum were assembled by hybrid assembly technique,and their intraspecic and interspecific differences were analyzed by comparative genomic method.Codon usage patterns and influencing factors were determined,and the cp genome data were applied to understand the phylogenomic relationships in the entire genus Polygonatum along with the available data.Methods In this study,the chloroplast genomes of 5 species of genus Polygonatum were assembled using Unicycler software.Sequence alignment,collinearity analysis,boundary analysis and other methods were used to evaluate the interspecific differences of these five species.Nucleotide polymorphism analysis was used to discover the high-variation sites of the five species and their related species,predict the distribution of different long repeat sequences and SSRs,and then analyze the use bias of Polygonatum code.Finally,phylogenetic tree was constructed with the coding sequences of other 47 genus Polygonatum and their closely related species to explore their phylogenetic relationships in this study.Results ①Chloroplast genomes of 155 408-155 623 bp were assembled from five species of Polygonatum.A total of 132-133 genes were annotated,and 369 long repeats and 1553 simple repeats were detected.②The contraction and expansion of chloroplast genomes in 8 species were not obvious at the IRs boundary,and the size and distribution of individual genes at the LSC-IRs-SSC boundary,such as ndhF gene and ycf1 gene,were slightly different.No interspecific or intraspecific rearrangement was observed in 8 species.③ The high-variation regions of the 8 chloroplast genomes are mainly located in two single-copy regions,the duplicate copy region is relatively conserved,and the coding region is more conserved than the non-coding region.High nucleotide polymorphic loci rps16-trnQ,trnS-trnG,trnTUGU-trnL,ndhF-rpl32 and rpl32-trnL are located in the single copy region and most of them are gene spacer regions.④ The codon preference results showed that the codon preference of the five species was similar and mainly affected by selection pressure,and the third base of the codon played A dominant role and mainly ended in A/U.RSCU clustering heat map shows that PK and PZ,PCB and PS have close relationship.⑤ Phylogenetic trees divided 52 species into five branches:Ⅰ,Ⅱ,Ⅲ,ⅣandⅤ.PS,PK,PCB,PCZ and PZ were divided into ⅣandⅤbranches,among which PK and PZ were most closely related,while PCZ was more distant than the other four,was divided into the Ⅴbranch alone.Conclusion This study provided a reference for the phylogenetic research and molecular marker development of the medicinal plants of the Polygonum genus.

Objective To provide scientific basis for layout planning and standardized cultivation the species of Chrysanthemum indicum complex in future periods,the potential ecological suitable areas was analyzed,.Methods By collecting distribution data of 1379 valid C.indicum complex species nationwide and 104 ecological factors,combined with MaxEnt model and ArcGIS software,the potential ecological distribution areas of C.indicum complex under 17 different climate scenarios was analyzed.Results Precipitation and solar radiation are key environmental variables affecting the suitable habitats of C.indicum complex.The most suitable regions for the growth of C.indicum complex was concentrated in Hubei(C.indicum L.),Shanxi(C.lavandulifolium),Jiangsu(C.nankingense),and Hubei(C.indicum var.aromaticum)regions.Under different scenarios,the suitable habitat area for C.indicum L.and C.lavandulifolium showed an overall decreasing trend,while those for C.indicum var.aromaticum and C.nankingense showed an expanding trend.The centroid shift indicates sensitivity of C.indicum complex to climate change.Conclusion The potential distribution areas of C.indicum complex is classified into ecological suitability levels,providing important reference for the sustainable use,introduction cultivation,and scientific zoning of related resources.

Objective:To investigate the association of skeletal muscle function(including muscle strength and physical performance) and insulin resistance as well as type 2 diabetes mellitus(T2DM).Methods:The retrospective study included 942 patients who visited the Department of Geriatrics at Renji Hospital, Shanghai Jiao Tong University School of Medicine, between October 2020 and July 2024. Low skeletal muscle function was defined as either reduced muscle strength or impaired physical performance. Muscle strength was assessed by grip strength, while physical performance was evaluated using the 5-time chair stand test. The associations between muscle function, insulin resistance, and T2DM were analyzed.Results:A significant association was observed between decreased skeletal muscle function and a higher prevalence of T2DM( P=0.001). Further analysis revealed that decreased physical performance was significantly associated with increased T2DM prevalence( P<0.001), whereas reduced muscle strength showed no significant association with T2DM prevalence( P=0.331). Linear regression analysis indicated that both the homeostasis model assessment of insulin resistance(HOMA2-IR) and fasting blood glucose levels increased significantly with longer chair stand times( P<0.05). Restrictive cubic spline(RCS) analysis demonstrated a nonlinear relationship between chair-rising time and HOMA2-IR. Notably, when the cumulative chair-rising time exceed 8.1 s, HOMA2-IR increased significantly with prolonged chair stand time. Logistic regression analysis showed that compared with patients with normal physical performance, those with decreased physical performance had significantly higher odds of T2DM( OR=2.64, P<0.001) and insulin resistance( OR=2.34, P=0.002). Conclusion:Decline in physical performance is significantly positively associated with insulin resistance and the risk of T2DM. Morever, when the cumulative chair stand time exceed 8.1 s, HOMA2-IR increases progressively with further prolongation of chair stand time.

Sarcopenia is characterized by a decline in both skeletal muscle mass and function. Since skeletal muscle is the primary organ responsible for insulin-stimulated glucose uptake, sarcopenia, which occurs with aging, is believed to promote insulin resistance in skeletal muscle, leading to disruptions in glucose metabolism. Growing clinical evidence indicates that decreased muscle function may contribute to the development of type 2 diabetes, while a reduction in muscle mass alone does not appear to be significantly associated with its onset. This review, based on the latest research, summarizes the clinical evidence linking sarcopenia to glucose metabolism abnormalities and potential mechanisms through which impaired muscle function affects glucose metabolism. The goal is to inspire early prevention, intervention, and management of type 2 diabetes by targeting skeletal muscle.

Objective To establish the phylogenic relationships among genus Botrychium,and to develop better molecular markers,along with to gain better understanding of cytonuclear coordination patterns of RuBisCO enzyme,the current article sampled two species(e.g.Botrychium ternatum(Thunb.)Sw.and Botrychium virginianum(L.)Sw.),and applied sequencing approaches for the data mining.Methods The assembly results of chloroplast(cp)genomes from B.ternatum and B.virginianum were determined via de novo hybrid assemble approach with the help of short reads(Illumina)and long reads(PacBio and Nanopore).Then the phylogenic relationships of 18 fern species were reconstructed based on the protein coding sequences from the cp genome and the rbcS gene,which were fished out of the RNA-seq data from SRA database,respectively.Then the adaptive selection and co-evolutionary analysis were employed to investigate the evolutionary trajectories of rbcL(cp genome)and rbcS(nuclear genome)genes.Results The full length of cp genome in the two genus Botrychium species were determined as 139 063 bp(NC_060644)and 139 372 bp(OR609363).Then 92 SSR sites and 78 SSR sites were identified in the current two cp genomes,respectively.The collinearity analysis showed high relevant relationship between the current two species,and significant relationship within both species among the inverted repeats regions.The adaptation and coevolution investigations illustrated the following results:①Coevolution network exists between RBCL and RBCS subunits from the fern RuBisCO enzyme.②Positively selected sites were significantly detected among both rbcL and rbcS genes.③Two coevolutionary pair sites from the two genes(e.g.site 11 in RBCL and site 106 in RBCS)were significantly positively selected,which may demonstrate a molecular pattern for the fern species fine-tuning the RuBisCO enzyme during the long earth history via the cytonuclear coordination.Conclusion Our current research shed a new light on the phylogenetic relationship of the genus Botrychium among the fern backbone-tree and provided amount of cpSSR sites with the potential as molecular markers for further population study on B.ternatum and B.virginianum.Moreover,our adaptation and coevolution investigations on rbcL and rbcS genes might indicate that the underlying cytonuclear coordination between the organelle and nuclear in cell of fern species for fine-tuning the key photosynthesis enzyme RuBisCO to gain better fitness according to the changing environment of earth during the geologic time-scale.
