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.

Sheep pox is widespread worldwide and is the most severe animal pox virus infection. This study aimed to identify the key microRNAs (miRNAs) differentially expressed in the exosomes of sheep poxvirus-infected cells and their target genes and related pathways and provide a theoretical basis for an in-depth understanding of the molecular mechanisms of sheep poxvirus-infected cells. In this study, the differentially expressed miRNAs were verified by quantitative polymerase chain reaction (qPCR), and the target genes of miRNAs were predicted and analyzed by bioinformatics. The qPCR results showed that the expression trends of oar-miR-21, oar-miR-10b, oar-let-7f, oar-let-7b, and oar-miR-221 were consistent with the sequencing results. The Gene Ontology and Kyoto Encyclopedia of Genes and Genomes results showed that differentially expressed miRNAs were mainly involved in the immune system processes of the Arf6 downstream pathway. The target genes Reactome pathways were mainly enriched in the RAC1 GTPase cycle, CDC42 GTPase cycle, RHO GTPase cycle, RHOV GTPase cycle, and post-transcriptional silencing of small RNAs. The transcription factors SP4, NKX6-1, MEF2A, SP1, EGR1, and POU2F1 that may be connected to sheep pox virus (SPPV)-infected cells were discovered by transcription factor annotation screening. In conclusion, this study screened for differentially expressed miRNAs in SPPV-infected cells and performed a series of bioinformatic analyses of their target genes to provide a theoretical basis for the molecular mechanism of sheep pox virus infections of cells. The data can be used as basic information in future studies on the defense mechanisms against poxvirus infections.

Objective:To investigate the correlation between hearing loss and microvascular complications in diabetes.Methods:This cross-sectional study conducted the data from 572 patients with diabetes hospitalized in the Endocrinology Department of the General Hospital of Southern Theater Command from September 2022 to July 2023. All participants underwent electrical audiometry and acoustic immittance in the ENY department. Based on the audiometric results, participants were categorized into normal hearing group and hearing loss group. Additionally, 572 non-diabetic patients from the outpatient department were enrolled as the non-diabetic group. The general information and laboratory results were collected and compared using t test, rank sum test or χ2 test. Binary logistic regression analysis was used to evaluate the association of diabetic hearing loss with diabetic kidney disease(DKD), diabetic retinopathy (DR), and diabetic peripheral neuropathy (DPN). Results:Among 572 patients with diabetes, 429 suffered from hearing loss and 143 were normal. χ2 test showed significant differences in combined DKD and DPN between two groups, but not in DR. Multivariate binary logistic regression analysis identified DKD and DPN as risk factors for hearing loss, but no correlation was found with DR. Conclusion:Diabetic patients with DKD or DPN should be monitored for potential hearing loss. Early screening and treatment are crucial to prevent severe hearing impairment.

Objective To evaluate the efficacy of Schroth PSSE combined with 3D printing braces in the treatment of adolescent idiopathic scoliosis.Method Forty patients were included and divided into a support group(3D printing support group)and a support+exercise therapy group(3D printing support+Schroth PSSE group).Excluding outliers and lost follow-up data,32 patients were ultimately included,with 16 patients in each group.Wearing time≥18 h for both groups of 3D printing supports.The intervention period of Schroth PSSE is 12 weeks,and exercise is maintained after 12 weeks until the end of follow-up.The longest follow-up time for the brace group was 25 months,with an average follow-up time of(15.00±1.29)months.The longest follow-up time for the brace+exercise therapy group was 24 months,with an average follow-up time of(16.59±1.01)months.Relevant indicators were evaluated after follow-up.Results The support and exercise therapy group showed better improvement in Cobb angle and trunk rotation angle(ATR)than the support group,with statistically significant differences(P<0.05);The distance between the midpoint of the C7 vertebral body and the midline of the sacrum(C7-CSVL)in the support and exercise therapy group showed a statistically significant difference before and after treatment(P<0.05),while there was a significant difference before and after Apical Vertebral Translation(AVT)treatment(P<0.01).There was no statistically significant difference compared to the support group(P<0.05);In terms of SRS-22 score,the brace+exercise therapy group can comprehensively improve the SRS-22 score.Conclusion The combination of Schroth PSSE and 3D printing braces has a better effect on improving Cobb angle and torso rotation angle,improving coronary imbalance,increasing patient satisfaction,and improving quality of life compared to using 3D printing braces alone.
