According to the pathological changes of cervical cancer， it is believed that traditional Chinese medicine can effectively prevent and treat through the following three stages. Firstly， during the stage of persistent high-risk human papilloma virus （HR-HPV） infection， the state before disease arises， it is advisable to prevent from arises. The disease mechanism of this stage is liver constraint and spleen deficiency， damp-turbidity retention， and modified Wandai Decoction （完带汤） can be used strengthen the spleen and soothe the liver， boost qi and dispel dampness. Secondly， at low-grade squamous intraepithelial lesions （LSIL） of the uterine cervix with persistent HR-HPV infection stage， the disease state， should control the development of existing disease， and the disease mechanism of this stage is depletion of qi and blood， combined with dampness and stasis. Modified Danggui Shaoyao Powder （当归芍药散） can be used to strengthen spleen， soften liver， promote blood circulation and drain water. Thirdly， after the surgery treatment of cervical precancerous lesions or cervical cancer， the post-treatment state， it is advisable to "prevent recurrence after treatment"， and the disease mechanism of this stage is co-existing of deficiency， stasis， and dampness with a small amount of cancer toxin. Prescriptions of modified Danggui Shaoyao Powder and Fangji Fuling Decoction （防己茯苓汤） can be used to boost qi， warm yang， invigorate blood and drain water， and also resolve toxins.

BACKGROUND:Changes in skeletal muscle mass have been indicated in studies addressing the effects of low-frequency pulsed magnetic fields on the structure and morphology of the skeletal muscle,but no relevant studies have been conducted on the morphologic changes that occur after chronic exposure to the low-frequency pulsed magnetic field. OBJECTIVE:To observe the effects of chronic exposure to low-frequency pulsed magnetic fields on the maximal voluntary contraction and morphologic indicators of the quadriceps muscle of the leg,thereby providing a reference of muscle morphologic changes for the use of this technique as a strategy for muscle function improvement. METHODS:Seventy healthy subjects were recruited and randomly divided into a test group that received magnetic field stimulation and a control group that underwent sham treatment,with 35 subjects in each group,and the total duration of the trial was 4 weeks.The test group underwent low-frequency pulsed magnetic stimulation for 15 minutes every 48 hours,while the control group underwent sham treatment,with the same intervention interval and duration as the test group.After 4 weeks of intervention,changes in the maximum voluntary contraction value of the quadriceps muscle in different groups were observed,and B-mode ultrasonography was utilized as a means of assessment to observe changes in muscle thickness,muscle cross-sectional area,and pinnation angle indexes. RESULTS AND CONCLUSION:After 4 weeks of chronic exposure to low-frequency pulsed magnetic fields,68 subjects completed the test.The maximum voluntary contraction value of the quadriceps muscle in the test group increased significantly(P=0.000),and the increment was significantly higher than that of the control group(P=0.008).Three indexes related to muscle morphology in the test group were significantly higher than the pre-test values(P=0.000),while in the control group,muscle thickness showed a significant reduction(P=0.020),there was no significant change in the pinnation angle,but a significant increase in the cross-sectional area(P=0.000).Intergroup comparisons revealed that the three indicators related to muscle morphology,including muscle thickness(P=0.012),pinnation angle(P=0.003),and cross-sectional area(P=0.049),were significantly higher in the test group than in the control group.The above data confirmed that the maximum voluntary contraction of the quadriceps muscle was significantly increased in healthy adults after 4 weeks of chronic exposure to the low-frequency pulsed magnetic field,and significant increases in the three muscle morphometric indices of muscle thickness,cross-sectional area,and pinnation angle were observed in the test group,providing a basis of muscle tissue morphology for the use of this technique as an exercise alternative and medical treatment strategy for muscle improvement.

The education concepts of four famous traditional Chinese medicine（TCM） doctors（XIAO Longyou， SHI Jinmo， KONG Bohua and WANG Fengchun） in Beijing during the Republic of China were compared， the commonalities in their education concepts of TCM were sorted out， and the root system of the cultivation and growth of talents in TCM， as well as the direction and way of further development were searched， so as to improve the quality of the inheritance and development of TCM. Based on the systematic review of text and opinion method（SrTO） developed by the centre for evidence-based health care at the Joanna Briggs Institute（JBI） in Australia， this study was conducted to collate and analyze the relevant information， including 14 books， 115 journal papers and 7 documents. Related theory construction and practice of early tutor and academic education have been summarized from college， continuing and tutor education， academic research， examination， and so on. And then the connections and commonalities between the different forms of education in the period were summarized to form a SrTO-based narrative， opinion， text assessment and review instrument（NOTARI） summary table. The findings revealed that these four esteemed TCM doctors and educators， through their substantial influence on TCM education in Beijing， emphasized the importance of classics in teaching and clinical practice， underscored the cultivation of virtue， preserved the traditional teaching model， and championed the establishment of TCM schools. They also put forward novel requisites for the compilation of curricula， teaching materials， and books. Moreover， they advocated for a unified perspective on TCM and western medicine， fostering talent capable of bridging the gap between the two. They encouraged the standardization of TCM teaching examination system， and actively participated in scientific research and book writing. The four TCM doctors transcended the traditional boundaries of TCM practice， fostering a new TCM model of education-clinical-research， and profoundly influencing the contemporary TCM colleges and teacher education.

Objective:To explore the latent profile of discharge readiness of patients with lower extremity arteriosclerosis obliterans and analyze its influencing factors, so as to provide theoretical basis for individualized management of discharge readiness in patients with lower limb arteriosclerosis obliterans.Methods:From February 2022 to December 2022, 194 patients with arteriosclerosis obliterans of lower limbs who received surgical treatment in the vascular surgery department of Shandong Provincial Hospital Affiliated to Shandong First Medical University were investigated by using general information questionnaire, Readiness for Hospital Discharge Scale, Quality of Discharge Teaching Scale and Family APGAR Index for a cross-sectional survey. Latent profile analysis was used to identify different categories, and Logistic regression analysis was used to explore its influencing factors.Results:Totally 182 valid questionnaires were collected, of which 127 males and 55 females, and patients over 60 years old were the majority, accounting for 81.9%. Three latent profile models were identified in this study, namely, low discharge readiness group (27.47%), medium discharge readiness-high expected support group (41.21%) and high discharge readiness group (31.31%). Logistic regression analysis showed that first hospitalization ( OR=19.218, 95% CI 2.949-125.237), the quality of discharge guidance ( OR=0.896, 95% CI 0.857-0.937) were the predictive factors of medium discharge readiness-high expected support group ( P<0.05); family function ( OR=0.185, 95% CI 0.097-0.353) and the quality of discharge guidance ( OR=0.823, 95% CI 0.764-0.888) were the predictive factors of the low discharge readiness group of patients with arteriosclerosis obliterans (all P<0.05). Conclusions:There are different types of discharge readiness of patients with arteriosclerosis obliterans, and patients with poor quality of discharge guidance and poor family function are more likely to have a trend of low discharge readiness. Patients with low quality discharge guidance and first hospitalization are more likely to have a trend of moderate discharge readiness-high expected support. For this kind of patients, medical staff should take corresponding measures to improve their readiness for discharge.

Objective:To investigate the effects and mechanisms of zinc ion-loaded composite hydrogel (hereinafter referred to as the zinc-containing hydrogel) on infected full-thickness skin defect wounds in diabetic mice.Methods:This study was an experimental study. A poly (glycerol sebacate)-co-poly(ethylene glycol)-g-catechol prepolymer/quaternized-chitosan hydrogel (hereinafter referred to as the simple hydrogel) and a solid-state zinc-containing hydrogel with porous and good adhesion by adding zinc ions to the simple hydrogel were prepared. The release rate of zinc ions from the zinc-containing hydrogel after immersion in phosphate buffer solution (PBS) for 14 days was calculated. The concentration of methicillin-resistant Staphylococcus aureus (MRSA) cultured for 2 hours with the simple hydrogel, zinc-containing hydrogel, and PBS was measured. The scavenging ability of the simple hydrogel, zinc-containing hydrogel, and PBS for 1,1-diphenyl-2-picrylhydrazyl radical 2,2-diphenyl-1-(2, 4, 6-trinitrophenyl) hydrazyl (DPPH) was detected using microplate reader to reflect the ability of oxygen free radical removal. The length of vessels formed by human umbilical vein endothelial cells (HUVECs) cultured for 24 hours with the simple hydrogel, zinc-containing hydrogel, and PBS was measured. The cell viability of L929 cells cultured for 24 hours with the simple hydrogel, zinc-containing hydrogel, and PBS was detected using the cell counting kit-8. The mouse red blood cell suspension was divided into blank control group treated with PBS, simple hydrogel group, zinc-containing hydrogel group, and Triton X-100 group treated with corresponding solution. Hemolysis was detected using microplate reader after 2 hours of treatment, and the hemolysis rate was calculated. All experiments had a sample size of 3. Twenty-one C57BL/6J mice aged 6-8 weeks were taken, and a full-thickness skin defect wound was prepared in the symmetrical position on the back spine and infected with MRSA. Mice were divided into blank control group treated with PBS, simple hydrogel group, and zinc-containing hydrogel group treated with the corresponding hydrogel. Three days after injury, bacterial concentration in the wounds were measured in all groups of mice ( n=4). On day 0 (immediately), 3, 7, and 14 after injury, the wound infection status of mice was generally observed and the wound healing rate was calculated ( n=5). Hematoxylin-eosin staining and Masson staining were used to detect new epithelium and collagen formation in the wounds of mice on day 14 after injury. Immunofluorescence staining was used to detect neovascularization and distribution of M2 macrophages in the wounds of mice. Results:After immersion for 14 days, the release rate of zinc ions of the zinc-containing hydrogel was (70.5±4.6)%. Compared with the zinc-containing hydrogel, the bacterial concentration was significantly increased after 2 hours of culture with PBS and the simple hydrogel ( P<0.05). The DPPH scavenging rate of the zinc-containing hydrogel was significantly higher than that of PBS and the simple hydrogel (with P values all <0.05). The length of vessels formed by HUVECs cultured for 24 hours with the zinc-containing hydrogel was significantly longer than that cultured with PBS ( P<0.05). Compared with PBS and the simple hydrogel, the cell viability of L929 cells cultured for 24 hours with the zinc-containing hydrogel was significantly higher ( P<0.05). After 2 hours of incubation, compared with that in Triton X-100 group, the hemolysis rate of red blood cells in blank control, simple hydrogel, and zinc-containing hydrogel groups was significantly reduced ( P<0.05); and the hemolysis rate of red blood cells in the latter three groups was similar ( P>0.05). On day 3 after injury, the bacterial concentration in the wounds of mice in zinc-containing hydrogel group was significantly lower than that in blank control and simple hydrogel groups (with P values all <0.05). From day 3 to day 14 after injury, the wounds of mice in all the three groups were gradually healing, and on day 14 after injury, the wounds of mice in the zinc-containing hydrogel group were basically healed. On day 7 after injury, the wound healing rate of mice in zinc-containing hydrogel group was (72.4±8.4)%, which was significantly higher than that of blank control and simple hydrogel groups, being (31.6±6.7)% and (44.7±5.4)%, respectively(with P values all< 0.05). On day 14 after injury, the wound healing rate of mice in zinc-containing hydrogel group was (92.7±4.3)%, which was significantly higher than (73.5±7.4)% in blank control group ( P<0.05). On day 14 after injury, compared with that in blank control and simple hydrogel groups, the newly formed epidermis in mice wound of zinc-containing hydrogel group was longer and thicker, with more collagen deposition, and a more abundant distribution of new vessels and M2 macrophages. Conclusions:The zinc-containing hydrogel exhibits good biocompatibility, oxygen free radical scavenging capacity, and antimicrobial effects both in vitro and in vivo, as well as angiogenic promotion capability. It can provide sustained release of zinc ions to promote re-epithelialization and collagen synthesis, thus enhancing the healing of infected full-thickness skin defect wounds in diabetic mice.

Objective:To understand the current and integrated disease burden and economic burden caused by breast cancer in females in China.Methods:Based on six updated data sources, including the series of Chinese Cancer Registry Annual Report, China Death Cause Surveillance Datasets, China Health Statistical Yearbook, GLOBOCAN, Cancer Incidence in Five Continents, Global Burden of Disease Study (GBD), the information about incidence, mortality and disability adjusted life years (DALY) of breast cancer were extracted for the analysis on the current incidence and time trend of breast cancer and predicted disease burden of breast cancer in females in China. Software Joinpoint was used for time trend analysis. The data of economic burden were systematically updated and analyzed by literature review.Results:1) GLOBOCAN 2022 estimated that the age-standardized incidence rate (ASIR) age-standardized mortality rate (ASMR) and one- year prevalence rate of breast cancer in females were 33.0/100 000, 6.1/100 000 and 40.1/100 000, respectively, in China in 2022. According to Chinese Cancer Registry Annual Report, the ASIR and ASMR were 28.4/100 000 and 5.8/100 000, respectively, in 2018. The China Death Cause Surveillance Datasets showed that the ASMR was 4.5/100 000 in 2021, and the urban to rural area mortality ratio was 1.2∶1. GBD reported that the DALYs of breast cancer were 2.921 million in China in 2021, accounting for 14.4% of the global total. 2) Chinese Cancer Registry Annual Report data showed that the ASIR and ASMR of breast cancer decreased by 2.1% and 11.4%, respectively, in China from 2009 to 2018, while increased by 43.9% and 8.2% in rural area, respectively. The Joinpoint analysis showed that the average annual percentage change (AAPC) of ASIR and ASMR in China were -0.2% ( P>0.05) and -1.6% ( P<0.05). The AAPC of ASIR and ASMR in rural area were 3.9% ( P<0.05) and 0.6% ( P>0.05), and -0.3% ( P>0.05) and -1.2% ( P<0.05) in urban area, respectively. China Health Statistical Yearbook data showed that the urban ASMR decreased by 12.3% from 2014 to 2021 with AAPC of -2.6% ( P<0.05). 3) The GLOBOCAN 2022 predicted that, the breast cancer case count and death count in China would be 387 776 and 111 133 by 2050, an increase of 8.6% and 48.2%, respectively, compared with 2022, the increases would be more obvious in people over 65 years old, an increase of 80.8% and 124.9%, respectively. 4) Thirteen individual- based studies reported that the median medical expenditure per patient ( M=21 000 to 39 000 Yuan) and length of hospital stay ( M=11.0 to 30.5 days) for breast cancer treatment decreased from 2010 to 2019, while the average medical expenditure per visit ( M=9 000 to 23 000 Yuan) showed an upward trend. There was only one national-level analysis, which showed that the treatment cost of breast cancer was 25.24 billion Yuan in China in 2018, accounting for 6.4% of the total cancer treatment cost. Conclusions:According to the above updated multi-source data, the incidence and mortality of female breast cancer in China were stable in the past ten years, but the increasing trend in rural area should be noted. The direct medical expenditure of breast cancer treatment per case might decrease, but the population-level economic burden would remain heavy due to population aging.

Objective To evaluate the degree of brain atrophy in spinocerebellar ataxia type 3(SCA3)patients based on artificial intelligence(AI)technology,and to explore the correlation between the degree of brain atrophy and the severity of the disease.Methods The clinical and imaging data of 23 SCA3 patients(SCA3 group)and 24 healthy controls(HC)(HC group)were collected.The International Cooperative Ataxia Rating Scale(ICARS)was used to evaluate the severity of ataxia in patients with SCA3.AI technology was used to process the 3D-T1 WI MR image data of the SCA3 and HC groups to segment and measure the volume and volume percentage of brain,followed by correlation analyses between brain structural alterations and the severity of ataxia in SCA3 patients.Results There were no significant differences in gender and age between the two groups(P＞0.05).The SCA3 group had a significant reduction in the volume and volume percentage of various brain regions,such as the frontal,temporal,parietal,occipital,limbic,right cerebral white mat-ter,subcortical gray matter,cerebellum and brainstem,compared to the HC group(multiple hypothesis testing adjusted P＜0.01).In the SCA3 group,the ICARS showed positive correlation with patient age(r=0.571,P=0.004)and negative correlation with the vol-ume of the left cerebellar white matter,vermis,medulla oblongata,and the volume percentages of bilateral cerebellar white matter,vermis,pons,medulla oblongata(P＜0.05).Conclusion The significant atrophy of the supratentorial and subtentorial regions of the brain in SCA3 patients.The globus pallidus exhibits the most substantial atrophy,suggesting its potential as an imaging diagnostic marker of SC A3.

Objective To investigate the contribution of microglia in the basolateral amygdala(BLA)to pain hypersensitivity and pain-related aversion in knee-joint monoarthritis mice.Methods A total of 61 mice were used for behavioral tests(14 mice in the control group and 47 mice in the model group),and other 6 mice were used for cell morphology(3 mice in each group).An animal model of knee-joint monoarthritis was established by injection of complete Freund's adjuvant(CFA)into the knee-joint cavity of mice.The von Frey and Hargreaves tests were used to examine mechanical allodynia and thermal hyperalgesia in mice,respectively.The place escape/avoidance paradigm test was used to examine pain-related aversion.Open field test and elevated plus maze test were used to examine anxiety-like behaviors in mice.Morphological changes of microglia in the BLA area after CFA injection were assessed by 3D reconstruction of microglia in the BLA brain region using immunofluorescence staining and Imaris software.Results Compared with the control group,CFA-arthritic mice produced significant mechanical and thermal hyperalgesia in the ipsilateral hindpaw and maintained for at least 12 and 19 days,respectively.Meanwhile,CFA injection induced pain-related aversion and anxiety-like behaviors in mice,accompanied by significant activation of BLA microglia.Inhibition of BLA microglia activation alleviated CFA-induced hyperalgesia and aversive behaviors but had no significant effects on anxiety-like behaviors.Conclusion CFA-arthritic mice produce hyperalgesia,pain-related aversion,and anxious behavior,in which hyperalgesia and pain-related aversion may be mediated by the activation of microglia in BLA.
