Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

The epidemiological and spatiotemporal clustering characteristics of dengue fever in Fujian Province were ana-lyzed,to provide a scientific basis for dengue fever prevention and control.Descriptive epidemiology,spatial autocorrelation a-nalysis,and spatiotemporal scanning were used to analyze dengue fever cases in Fujian Province from 2011 to 2023.In this peri-od,a total of 3 586 cases of dengue fever were reported in Fujian Province,including 2 360 local cases,1 134 imported cases from abroad,and 92 imported cases from China.Cases were reported in ten prefectures and cities of the province,and 81 out of 88 counties reported cases.Imported cases were reported throughout the year in Fujian Province,but the occurrence of local ca-ses showed clear seasonality.Local cases and domestic imports were concentrated in August to October,whereas overseas im-ports occurred primarily from June to October.The imported cases were mainly from Southeast Asian countries,but a trend of spreading from Southeast Asian countries to South Asia,Africa,the Americas,and other regions,was observed.Spatio-tem-poral clustering of dengue fever was found in Fujian Province(Moran's I value 0.14-0.66,P＜0.05),and the high-high ag-gregation areas were distributed primarily in Fuzhou,Quanzhou,and Putian.Spatio-temporal scanning detected three aggrega-tion areas:one main and two secondary.The aggregation time was from the end of July to October,and the distribution was primarily in Fuzhou,Quanzhou,Putian,Zhangzhou,and Xiamen.The distribution of dengue fever in Fujian Province showed clear spatial and temporal clustering from the end of July to October,and the distribution was primarily in Fuzhou,Quanzhou,Putian,Zhangzhou,and Xiamen.For high concentration areas,national health campaigns,mosquito prevention and control,epidemic surveillance,medical personnel training,and other relevant measures could be carried out in advance before local cases appear every year.Reduce local transmission of dengue fever due to importation.

Objective Vascular dementia(VD)is a common cognitive dysfunction associated with cerebrovascular disease.This study is aimed at investigating the therapeutic effect of anisodine hydromide(AH)on VD and the potential antioxidative stress mechanisms involved.Methods A VD model was established in Sprague-Dawley(SD)rats through permanent bilateral common carotid artery occlusion.The rats were divided into a sham group,a VD model group,and AH treatment groups receiving AH at low,medium,or high doses(n=4).The neurological function of the rats in each group was evaluated using the Bederson scale,and limb coordination ability was assessed using the pole climbing test.Superoxide dismutase(SOD)and malondialdehyde(MDA)levels in the serum and brain were measured by enzyme-linked immunosorbent assay(ELISA)to assess the level of oxidative stress.In addition,apoptosis was assessed by TUNEL assay,and reactive oxygen species(ROS)levels in neuronal cells were determined using dichloro-dihydro-fluorescein diacetate(DCFH-DA)probe.The potential mechanism of action of AH on M receptors was investigated using M1-M5 inhibitors.Results Compared with the sham group,the nerve function and limb coordination of rats in the VD model group were significantly impaired(P＜0.01),and the SOD levels were significantly decreased in the serum([100.70±18.95]U/mL vs.[44.22±7.11]U/mL,P＜0.001)and the brain([131.77±8.34]U/mg vs.[84.39±4.10]U/mg,P＜0.01),MDA levels were significantly increased in the serum([12.03±1.01]nmol/mL vs.[17.74±1.00]nmol/mL,P＜0.001)and the brain([4.41±0.30]nmol/mg vs.[6.17±0.70]nmol/mg,P＜0.05).AH treatment significantly improved the neurological function and limb coordination ability of VD rats.In comparison with the VD group,the high-dose AH treatment group,in particular,exhibited the most significant increase in SOD levels in the serum([44.22±7.11]U/mL vs.[98.67±0.86]U/mL,P＜0.001)and the brain([84.39±4.10]U/mg vs.[162.83±17.36]U/mg,P＜0.001),and the most significant decrease in MDA levels in the serum([17.74±1.00]nmol/mL vs.[6.68±0.06]nmol/mL,P＜0.001)and the brain([6.17±0.70]nmol/mg vs.[3.96±0.77]nmol/mg,P＜0.01).AH also reduced the number of TUNEL positive cells(P＜0.01)in a dose-dependent manner.The percentage of apoptotic cells was(36.10±9.07)％,(9.60±5.63)％,and(3.43±0.92)％,respectively,for AH treatment at low,medium,and high concentrations,indicating that AH had an inhibitory effect on apoptosis.According to findings from the in vitro experiments,AH treatment reduced the MDA content(P＜0.01),increased the SOD activity(P＜0.01),and decreased the ROS levels of HT22 and NSC-34 cells in a dose-dependent manner.M2 receptor inhibitors could reduce the ROS level in oxidative stress injury,suggesting that AH,as an M receptor antagonist,might exert its effect by inhibiting the M2 receptor.Conclusion AH modulates SOD and MDA levels and reduces oxidative stress injury,thereby improving neurological function and limb coordination and showing potential therapeutic effects in VD.The neuroprotective effects of AH may be related to its antioxidative stress and antiapoptotic mechanisms,and the M2 receptor may be a potential target of its actions.These findings provide an important theoretical basis for the development of new therapeutic strategies for VD.

Aim To explore the effects of Huannao Yicong decoction(HYD)on the learning and memory ability and brain iron metabolism in APP/PS1 mice and the correlation of HAMP knockout mice and APP/PS1 double transgenic model mice.Methods The ex-periment was divided into five groups,namely,HAMP-/-group(6-month HAMP gene knockout mice),APP/PS1 group(6-month APP/PS1-double-transgenic mice),HAMP-/-+HYD,APP/PS1+HYD,and negative control group(6-month C57BL/6J mice),with six mice in each group.The dose was ad-ministered(13.68 g·kg-1 weight),and the other groups received distilled water for gavage once a day for two months.After the administration of the drug,the mice in each group were tested for learning and memory in the Morris water maze;Biochemical detec-tion was performed to detect iron ion content in each mouse brain;Western blot and RT-qPCR were carried out to analyze hippocampal transferrin(TF),transfer-rin receptor1(TFR1),membrane iron transporter1(FPN1)divalent metal ion transporter 1(DMT1)and β-amyloid protein(Aβ)protein and mRNA expression levels in each group.Results Compared with the normal group,both HAMP-/-mice and APP/PS1 mice had reduced the learning and memory capacity,in-creased iron content in brain tissue,Aβ protein ex-pression increased in hippocampus of HAMP-/-group and APP/PS1 group mice(P＜0.01),the protein and mRNA expression of TF,TFR1 and DMT1 increased in hippocampal tissues of HAMP-/-and APP/PS1 groups(P＜0.01),and the FPN1 protein and mRNA expres-sion decreased(P＜0.01).Compared with the HAMP-and APP/PS1 groups,respectively,HAMP-/-+HYD group and APP/PS1+HYD group had improved learning and memory ability,decreased iron content,decreased Aβ protein expression(P＜0.01),decreased TF,TFR1,DMT1 protein and mR-NA expression(P＜0.01),and increased expression of FPN1 protein and mRNA(P＜0.01).Conclusions There is some association between HAMP-/-mice and APP/PS1 mice,HYD can improve the learning and memory ability of HAMP-/-and APP/PS1 mice and reduce the Aβ deposition.The mechanism may be related to the regulation of TF,TFR1,DMT1,FPN1 expression and improving brain iron overload.

Aim To investigate the enhanced efficacy and reduced toxicity of GanoExtra in combination with cyclophosphamide(CTX)on inhibiting lung metastasis and immune function in mice.Methods The CCK-8 method was used to verify the cytotoxic effects of Gano-Extra on MCF-7 and 4T1 tumor cells.In vivo experi-ment,a mouse model of lung metastasis of breast canc-er was established by injecting 4T1 tumor cells into the tail vein,which was divided into four groups including 4T1 model group,CTX group,GanoExtra group and GanoExtra+CTX group.The control group was set.After 21 days,the mice were euthanized under anes-thesia,and the body weight of the mice was recorded.Average lung index and spleen index were calculated.The mouse spleen lymphocyte transformation experi-ment was used to determine the activity of spleen cells.The NK cell activity assay was used to determine the activity of NK cells.Blood cells were determined in mouse blood samples.Flow cytometry was used to de-termine the levels of CD4+and CD8+T cells in blood samples.ELISA was used to measure the levels of TNF-α and IL-6 in serum.HE staining was used to ob-serve the pathological morphological changes in tumors and various tissues;and CFSE staining was used to de-termine the proliferative effect of GanoExtra on CD8+cells.Results In vitro GanoExtra at 50 mg·L-1 sig-nificantly inhibited the activity of MCF-7 and 4T1 tumor cells.In the breast cancer pulmonary metastasis model,compared with the model group,the spleen in-dex and blood WBCs content were significantly re-duced,while the activity of NK cells,spleen cells,and the proportion of RBCs,CD 3+and CD 8+T cells in the blood were significantly increased.At the end of the treatment,compared with the CTX group,the number of lung metastases and lung index of the Gano-Extra+CTX group were significantly reduced,and the levels of HGB,CD8+cells,IL-6,and TNF-α in the blood of mice were significantly increased.GanoExtra at 10 mg·L-1 significantly promoted the proliferation of CD8+T cells in vitro.Conclusions GanoExtra can enhance the inhibitory effect of CTX on tumor metasta-sis,alleviate adverse reactions such as splenomegaly and pulmonary enlargement caused by CTX,and have a health-promoting function of promoting the prolifera-tion of CD8+T cells to enhance the immune efficacy of the body.

Immmunosuppressants are mainly used to reduce rejection after solid organ transplantation,so as to improve the success rate of organ transplantation.However,long-term use of immunosuppressants can also serious-ly impair the immune function of patients,thereby increasing the risk of viral infection and postoperative complica-tions,leading to transplant failure.Therefore,patients need to use both immunosuppressants and antiviral agents.If some immunosuppressants with antiviral effects are found,the patient's burden of taking medicines will be greatly reduced.Currently,the immunosuppressants with antiviral effect have been focused by researchers.The gradual re-vealing of the antiviral mechanism of these immunosuppressants will help to optimize the treatment plan of postope-rative rehabilitation of organ transplant recipients.Based on the mechanism of rejection of transplanted organ,this paper systematically describes the types of viruses which closely related to infection of organ transplant patients and the molecular mechanism of some immunosuppressants in antiviral aspects,which further provides a new idea for clinical prevention and treatment of viral infection due to organ transplantation.

Objective To analyze the factors affecting the prognosis of patients with knee osteoarthritis,and to construct a nomogram prediction model in conjunction with multi-dimensional clinical indicators.Methods The clinical data of 234 pa-tients with knee osteoarthritis who were treated in our hospital from January 2015 to June 2021 were retrospectively analyzed,including 126 males and 108 females;age more than 60 years old for 135 cases,age less than 60 years old for 99 cases.Lysholm knee function score was used to evaluate the prognosis of the patients,and the patients were divided into good progno-sis group for 155 patients and poor prognosis group for 79 patients according to the prognosis.The clinical data of the subjects in the experimental cohort were analyzed by single factor and multiple factors.The patients were divided into experimental co-hort and verification cohort,the results of the multiple factor analysis were visualized to obtain a nomogram prediction model,the receiver operating characteristic curve(ROC),calibration curve and decision curve were used to evaluate the model's dis-crimination,accuracy and clinical benefit rate.Results The results of multivariate analysis showed that smoking,pre-treatment K-L grades of Ⅲto Ⅳ,and high levels of interleukin 6(IL-6)and matrix metallo proteinase-3(MMP-3)were risk factors for the prognosis of patients with knee osteoarthritis.ROC test results showed that the area under the curve of the nomogram model in the experimental cohort and validation cohort was 0.806[95％CI(0.742,0.866)]and 0.786[(95％CI(0.678,0.893)],re-spectively.The results of the calibration curve showed that the Brier values of the experimental cohort and verification cohort were 0.151 points and 0.134 points,respectively.When the threshold probability value in the decision curve was set to 31％,the clinical benefit rates of the experimental cohort and validation cohort were 51％and 56％,respectively.Conclusion The prognostic model of patients with knee osteoarthritis constructed based on multi-dimensional clinical data has both theoretical and practical significance,and can provide a reference for taking targeted measures to improve the prognosis of patients.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective To construct microscale rectangular hydrogel grooves and to investigate the morphology and alignment of human umbilical vein endothelial cells(HUVECs)under spatial constraints.Vascular endothelial cell morphology and alignment are important factors in vascular development and the maintenance of homeostasis.Methods A 4-arm polyethylene glycol-acrylate(PEG-acrylate)hydrogel was used to fabricate rectangular microgrooves of the widths of 60 μm,100 μm,and 140 μm.The sizes and the fibronectin(FN)adhesion of these hydrogel microgrooves were measured.HUVECs were seeded onto the FN-coated microgrooves,while the flat surface without micropatterns was used as the control.After 48 hours of incubation,the morphology and orientation of the cells were examined.The cytoskeleton was labelled with phalloidine and the orientation of the cytoskeleton in the hydrogel microgrooves was observed by laser confocal microscopy.Results The hydrogel microgrooves constructed exhibited uniform and well-defined morphology,a complete structure,and clear edges,with the width deviation being less than 3.5%.The depth differences between the hydrogel microgrooves of different widths were small and the FN adhesion is uniform,providing a micro-patterned growth interface for cells.In the control group,the cells were arranged haphazardly in random orientations and the cell orientation angle was(46.9±1.8)°.In contrast,the cell orientation angle in the hydrogel microgrooves was significantly reduced(P<0.001).However,the cell orientation angles increased with the increase in hydrogel microgroove width.For the 60 μm,100 μm,and 140 μm hydrogel microgrooves,the cell orientation angles were(16.4±2.8)°,(24.5±3.2)°,and(30.3±3.5)°,respectively.Compared to that of the control group(35.7%),the number of cells with orientation angles<30° increased significantly in the hydrogel microgrooves of different widths(P<0.001).However,as the width of the hydrogel microgrooves increased,the number of cells with orientation angles<30° gradually decreased(79.9%,62.3%,54.7%,respectively),while the number of cells with orientation angles between 60°-90° increased(P<0.001).The cell bodies in the microgrooves were smaller and more rounded in shape.The cells were aligned along the direction of the microgrooves and corresponding changes occurred in the arrangement of the cell cytoskeleton.In the control group,cytoskeletal filaments were aligned in random directions,presenting an orientation angle of(45.5±3.7)°.Cytoskeletal filaments were distributed evenly within various orientation angles.However,in the 60 μm,100 μm,and 140 μm hydrogel microgrooves,the orientation angles of the cytoskeletal filaments were significantly decreased,measuring(14.4±3.1)°,(24.7±3.5)°,and(31.9±3.3)°,respectively.The number of cytoskeletal filaments with orientation angles<30° significantly increased in hydrogel microgrooves of different widths(P<0.001).However,as the width of the hydrogel microgrooves increased,the number of cytoskeletal filaments with orientation angles<30° gradually decreased,while the number of cytoskeletal filaments with orientation angles between 60°-90° gradually increased(P<0.001).Conclusion Hydrogel microgrooves can regulate the morphology and orientation of HUVECs and mimic to a certain extent the in vivo microenvironment of vascular endothelial cells,providing an experimental model that bears better resemblance to human physiology for the study of the unique physiological functions of vascular endothelial cells.Nonetheless,the molecular mechanism of spatial constraints on the morphology and the assembly of vascular endothelial cell needs to be further investigated.
