As one of the core pathogenesis during treatment with traditional Chinese medicine，liver heat runs through different stages of liver disease. The interpretation of its meaning in different medicine categories（traditional Chinese medicine，Tibetan medicine，Mongolian medicine，Uygur medicine，Dai medicine，Yao medicine，etc.） is not unified， and the phenomena of the same name with different meanings，confusion， and misappropriation emerge. This seriously restricts the inheritance，innovation， and clinical application of traditional Chinese medicine and ethnomedicine. By tracing and analyzing liver heat， it is found that liver heat in traditional Chinese medicine is caused by disordered rest and diet， as well as internal injury due to emotional disorder， which leads to liver dysfunction， Qi stagnation， and heat turning to fire in the liver meridian. The liver heat in Tibetan medicine is caused by the accumulated heat of the liver nature and the evil heat in the liver， which stimulates the toxin of Chiba fever. The liver heat in Mongolian medicine derives from the abnormal diet and rest， making excessive Sheila accumulate in the liver and causing disease. The above etiologies are all related to diet， rest，exogenous evil，emotion，and so on， and the pathogenesis is related to the imbalance of Qi and the metabolic disorder of organs. The clinical symptoms are pain in the liver region，yellow eyes， bitter mouth， fever，digestion，and loss of appetite. The principle of treatment and compatibility of prescription are heat-based， with auxiliary detoxification. Other ethnomedicine， such as Uygur medicine， Dai medicine， Yao Medicine，Miao medicine， and She medicine do not have a clear discussion on liver heat，and their etiology， pathogenesis， treatment，and prescription are not systematic，mostly based on a single drug or proven prescriptions.Through the systematic tracing，mining，induction，analysis， and arrangement of the liver heat based on existing literature information database in China，this paper regarded syndrome as the outline and disease as the goal，clarified the similarities and differences of the pathogenesis of liver heat in traditional Chinese medicine，and determined the relationship between liver heat and liver disease and the status quo of syndrome and treatment.This review provides evidence and reference for clinical prevention and treatment，as well as drug development for liver disease.

Objective:To evaluate the effect of venous excess ultrasound score (VExUS Score) in the acute kidney injury(AKI) in Patients with sepsis, so as to reduce the risk of disease and improve the prognosis of patients.Methods:This experiment was a single-center prospective cohort study. Include septic patients with AKI who were admitted to the Department of Emergency Intensive Care Unit of the First Affiliated Hospital of Anhui Medical University from February 2022 to February 2023, Those with inadequate window, inferior vena cava (IVC) thrombus, age<18 years and known case of cirrhosis with portal hypertension were excluded from the study. Patients underwent ultrasound examination with serial determination till AKI resolved or patient is initiated on dialysis.Results:Totally 86 patients were enrolled for the study. The mean age was (60.43±15.48) with 50 (58.1%) males. Mean sequential organ failure assessment (SOFA) score was (6.23±1.87). 38 patients (44.2%) were in AKI stage 1, while 24 patients (27.9%) were in AKI stage 2 and stage 3 each. 52 patients (60.5%) had VExUS grade Ⅲ. Resolution of AKI injury showed significant correlation with improvement in VExUS grade ( p value 0.003). Similarly, there was significant association between changes in VExUS grade and fluid balance ( p value 0.005). There was no correlation between central venous pressure (CVP), left ventricular function, and right ventricular function with change in VExUS grade. Conclusions:The study shows a significant correlation between the VExUS Score and AKI staging, With improvement in kidney function, there is decline in the VExUS grade as well. Moreover VExUS Score might reliably demonstrate venous congestion and aid in the clinical decision to perform fluid removal.

Objective To observe the value of intratumoral and peritumoral radiomics based on diffusion weighted imaging(DWI)for predicting histological grade of breast cancer.Methods Preoperative DWI data of 700 patients with single breast cancer diagnosed by pathology were retrospectively analyzed.The patients were divided into training set(n= 560,including 381 of grade Ⅰ+Ⅱ and 179 of grade Ⅲ)and test set(n=140,including 95 of grade Ⅰ+Ⅱ and 45 of grade Ⅲ)at the ratio of 8∶2.Intratumoral ROI(ROIintra)was manually delineated on DWI,which was automatically expanded by 3 mm and 5 mm to decline peritumoral ROI(ROIperi,including ROI3 mm and ROI5 mm),then intratumoral-peritumoral ROI(ROIintra+3 mm,ROIintra+5 mm)were obtained.The optimal radiomics features were extracted and screened,and the radiomics model(RM)for predicting the histological grade of breast cancer were constructed.Receiver operating characteristic curves were drawn,and the areas under the curve(AUC)were calculated to evaluate the predictive efficacy of each model.Calibration curve method was used to evaluate the calibration degree,while decision curve analysis(DCA)was performed to explore the clinical practicability of each model.Results AUC of RMintra,RM+3 mm,RM+5mm,RMintra+3 mm and RMintra+5 mm was 0.750,0.724,0.749,0.833 and 0.807 in training set,while was 0.723,0.718,0.736,0.759 and 0.782 in test set,respectively.In training set,significant differences of AUC was found(all P＜0.01),while in test set,no significant difference of AUC was found among models(all P＞0.05).The calibrations of models were all high.DCA showed that taken 0.02-0.88 as the threshold,the clinical net benefit of RMintra+per were greater in training set,while taken 0.40-0.72 as the threshold,the clinical net benefit of RMintra+per was greater in test set.Conclusion Both DWI intratumoral and peritumoral radiomics could effectively predict histological grade of breast cancer.Combination of intratumoral and peritumoral radiomics was more effective.

Objective:To explore the application and diagnostic value of low-dose scan technique of chest computed tomography(CT)combined with three dimensional(3D)reconstruction for ribs in chest trauma.Methods:A total of 118 patients with highly suspected rib fracture who admitted to the 904th Hospital of People's Liberation Army Joint Service Support Force were selected,and all cases underwent low-dose scan technique of chest CT combined with 3D reconstruction for ribs.The image qualities of chest CT scans with different low-doses combined with 3D reconstruction for ribs were analyzed,and the diagnostic accuracies among low dose scan technique of chest CT,3D reconstruction for ribs and the combination of them for chest trauma were compared.Results:Both the sharpness and clarity of the edges of the bronchi,blood vessels,lung parenchyma,interlobular septum,mediastinum and ribs were poorer,and the artifacts of soft tissue were more and the noise were more when the tube current of CT scan was 50 Ma.Both the sharpness and clarity of the edges of the bronchi,blood vessels,lung parenchyma,interlobular septum,mediastinum and ribs were general,and a part of soft tissues existed artifacts and the noise amounts were less when the tube current of CT scan was 70 Ma,which did not affect the diagnosis.The radiation dose as 50 mA was significantly higher than that as 70 mA,with a statistically significant difference(t=10.969,P<0.05).In 118 patients with chest trauma,the examination of low-dose scan technique of chest CT combined with 3D reconstruction for ribs indicated that there were 112 cases of rib fractures and 7 cases of costal cartilage fractures.In the examined 388 fractures of rib and costal cartilage,355 fractures(91.49%)were rib fractures and 33 fractures(8.51%)were costal cartilage fractures.In 118 patients with chest trauma,76 cases(64.41%)complicated with pulmonary contusions and lacerations,and 41 cases(35.75%)complicated with pleural effusion,and 10 cases(8.47%)complicated with thoracic vertebral fractures,and 6 cases(5.08%)complicated with splenic contusions and lacerations,and 5 cases(4.24%)complicated with mediastinal and subcutaneous emphysemas.The most direct imaging sign of rib fracture was visible and transparent low-density shadow.Chest CT scan can generally better display dislocation of the fractured end.The 3D reconstruction image showed a visibly line-like shadow on one side of rib if only one side of ribs fractured and the other side was intact.A total of 395 rib and costal cartilage fractures were confirmed by 3D reconstruction,which included 363 rib fractures(91.90%)and 32 costal cartilage fractures(8.10%).A total of 410 rib and costal cartilage fractures were confirmed by low-dose scan technique of chest CT combined with 3D reconstruction for ribs,which included 375 rib fractures(91.46%)and 35 costal cartilage fractures(8.54%).In the comparison of 418 rib injuries that were confirmed during surgery,the accuracy of low-dose scan technique of chest CT was 92.82%(388/418)in diagnosing rib and costal cartilage fractures,and the accuracy of 3D reconstruction for ribs was 94.50%(395/418)in diagnosing that,and the accuracy of low-dose scan technique of chest CT combined with 3D reconstruction for ribs was 95.69%(410/418)in diagnosing that.There was a significant difference in accuracy among the three types of examinations(x2=13.062,P<0.05).Conclusion:Low dose scan technique of chest CT combines with 3D reconstruction for ribs can be used in the diagnosis of chest trauma,which has higher accuracy and can provide reliable imaging information for clinical diagnosis and treatment.

Objective:To characterize the biomechanics of distal dynamic locking and distal static locking of proximal femur bionic nails (PFBN) in fixation of intertrochanteric fractures by a finite element analysis.Methods:The CT image data from the hip to the upper tibia from an adult male volunteer were used to establish a three-dimensional model of the femur by Mimics 20.0 and Geomagic 2013 which was processed further into a model of Evans type I intertrochanteric fracture by software NX 12.0. With reference to the internal fixation parameters commonly used, 4 models of PFBN fixation were established: distal single transverse nail dynamic locking (model A), single oblique nail dynamic locking (model B), single nail static locking (model C) and double nail dynamic locking (model D). Abaqus 6.14 software was used to load and analyze the internal fixation stresses and displacements of fracture ends.Results:Under a 2100N loading, the peak stress was located upon the main nail in the 4 models. The smallest peak stress upon the main nail was in Model D (161.9 MPa), decreased by 15.9% compared with model A (192.5 MPa), by 15.6% compared with model B (191.9 MPa), and by 0.9% compared with model C (163.3 MPa). The peak stress upon the fixation screw was the largest in model A (95.3 MPa), the smallest in model B (91.5 MPa), and 91.5 MPa and 92.2 MPa in models C and D, respectively. The overall displacements of the implants, in a descending order, were 10.14 mm in model A, 10.10 mm in model B, 10.09 mm in model C, and 10.05 mm in model D. Similarly, the displacements of fracture ends were 0.125 mm in model A, 0.121 mm in model B, 0.110 mm in model C, and 0.098 mm in model D.Conclusion:Compared with dynamic locking, distal static locking of PFBN provides a better mechanical stability and reduces stress concentration upon internal fixation.

Objective:To analyze the effect of risk assessment grading nursing based on adverse events(violence,suicide and runaway)on the efficacy and incidence of adverse events in patients with schizophrenia(SP).Methods:A total of 134 SP patients who received standardized in-hospital treatment in our hospital from Jun 2022 to Jun 2023 were selected.They were divided into routine nursing group and graded nursing group by random number table method,67 cases in each group.The routine nursing group was given routine nursing intervention during hospitalization,and the graded nursing group was given graded nursing with adverse event risk assessment on the basis of routine nursing.The incidence of adverse events,treatment compliance,efficacy[positive symptoms of positive and negative syndrome scale(PANSS)]and quality of life[schizophrenia quality of life scale(SQLS)]between the two groups were compared.Results:After intervention,the incidence of adverse events in graded nursing group was lower than that in routine nursing group(P＜0.05).The treatment compliance rate of graded nursing group was higher than that of routine nursing group(P＜0.05).The positive,negative,psychopathological,motivation/energy,symptom/side effect,and psychosocial scores in graded nursing group were lower than those in routine nursing group(P＜0.05).Conclusion:Graded nursing with adverse event risk assessment can improve the treatment compliance of SP patients,reduce the occurrence of adverse events,improve the curative effect and quality of life.

Objective The present study aimed to explore the effects of CC-chemokine receptor 5 antagonism on tumor growth and immune microenvironment.Methods Cell Counting Kit-8 was used to detect in vitro anti-proliferation activity of maraviroc,a selective CC-chemokine receptor 5 inhibitor,on Lewis cells,a mouse lung adenocarcinoma cell strain.Flow cytometry and real-time quantitative PCR were respectively used to detect cell apop-tosis and Caspase 8 gene expression.In a congenic mouse lung cancer model,the mice were intraperitoneally admin-istered with maraviroc or vehicle.Tumor sizes were measured and tumor infiltrating CD4+,CD8+ and Foxp3+ cells were determined by immunofluorescent staining.Results Our results showed that maraviroc could inhibit the growth of Lewis cancer cells not only in vitro but also in vivo.This in-vitro inhibition was presumably attributable to apoptosis induction by the enhancement of Caspase 8 gene expression after maraviroc blockade.Additionally,more CD4+ and CD8+ cells but less Foxp3+ cells were detected in tumor mass from the mice administered with maraviroc.Conclusions Taken together,it can be speculated that CCR5 blockade may inhibit the growth of Lewis cells by inducing cell apoptosis and impairing the immunosuppressive tumor microenvironment.It is worthy of further investi-gation as a candidate for cancer therapy.
