Objective To explore the influencing factors on foot function recovery after distraction device-assisted repositioning of small incisions treatment for Sanders Ⅱ and Ⅲ calcaneal fractures,and to provide guidance for timely clinical interventions.Methods A retrospective analysis was conducted on 80 patients with Sanders type Ⅱ and Ⅲ calcaneal fractures admitted to the People's Hospital of Bozhou from January 2021 to June 2023.Data were collected using a general information questionnaire,the hospital's electronic medical record system,the visual analog scale(VAS),the Marland foot function scale(MFS),the perceived social support scale(PSSS),and the perceived stress scale(PSS).The influencing factors of postoperative foot function recovery were analyzed using univariate factor analysis,multivariate linear regression,and structural equation modeling.Results The MFS scores of 80 patients at 6 months post-operation were significantly higher than preoperative scores(P＜0.001).The rates of excellent,good,fair,and poor foot function at 6 months post-operation were 56.3％,31.3％,10.0％,and 2.5％,respectively.Univariate analysis revealed significant differences in MFS scores based on different ages,time to start full weight-bearing exercise,bone mineral density,surgical timing,body mass index(BMI),postoperative VAS score,PSSS score,PSS score,and the presence of postoperative peroneal muscle spasm and peroneal muscle tendon adhesion(P＜0.05).Multivariate linear regression identified age,time to start full weight-bearing exercise,surgical timing,BMI,postoperative fibular muscle spasm,postoperative fibular muscle tendon adhesion,postoperative VAS score,PSSS score,and PSS score as significant factors affecting foot function recovery(P＜0.05).Structural equation modeling indicated that age,time to start full weight-bearing exercise,bone density,operative timing,BMI,postoperative peroneal muscle spasm,postoperative peroneal tendon adhesion,and pain severity directly influenced postoperative foot functional recovery.Additionally,psychological stress not only directly affected postoperative foot functional recovery but also indirectly influenced it through the mediating effect of social support.Conclusions Foot function recovery after surgery for Sanders type Ⅱ and Ⅲ calcaneal fractures is influenced by multiple factors.Psychological stress not only directly affects the recovery of foot function after surgery,but also mitigates the harm to foot function through social support.

Objective To investigate the awareness of female patients with pelvic floor dysfunction regarding minimally invasive laser treatment of the reproductive tract and analyze the factors influencing their decision-making intentions,this study aims to provide a foundation for early treatment of pelvic floor dysfunction and further development in reproductive health management.Methods A convenience sampling method was employed to select 164 female patients with pelvic floor dysfunction who sought treatment at the Pelvic Rehabilitation Center of Dongguan Maternal and Child Health Care Hospital between June 2023 and August 2024.The study utilized the Female Sexual Function Index,Incontinence Quality of Life Questionnaire,and Family Support Self-Assessment Scale to conduct a survey.Binary logistic stepwise regression analysis was conducted to investigate the factors influ-encing patients'inclination towards undergoing genital laser minimally invasive treatment.Results Among the 164 female patients,143(87.2%)expressed an intention to receive treatment,with 22.6%demonstrating a rela-tively clear understanding of genital laser minimally invasive treatment.Logistic regression analysis revealed that occupation significantly influenced treatment intention(P<0.05).Compared to healthcare professionals,individuals in the teaching profession(OR=10.81,95%CI:1.04～112.21),self-employed individuals(OR=20.34,95%CI:3.46～119.43),and those in other professions(OR=16.26,95%CI:4.05～65.29)were more inclined to express willingness for undergoing treatment.Furthermore,a lower score on the Incontinence Quality of Life scale was found to positively correlate with treatment intention(OR=0.96,95%CI:0.93～0.99).Conclusion Although patients express a high intention to undergo minimally invasive genital laser treatment,their overall awareness of the procedure remains insufficient.

Objective To explore early postoperative gait characteristics and clinical outcomes after total knee arthroplasty(TKA).Methods From February 2023 to July 2023,26 patients with unilateral knee osteoarthritis(KOA)were treated with TKA,including 4 males and 22 females,aged from 57 to 85 years old with an average of(67.58±6.49)years old;body mass in-dex(BMI)ranged from 18.83 to 38.28 kg·m-2 with an average of(26.43±4.15)kg·m-2;14 patients on the left side,12 pa-tients on the right side;according to Kellgren-Lawrence(K-L)classification,6 patients with grade Ⅲ and 20 patients with grade Ⅳ;the courses of disease ranged from 1 to 14 years with an average of(5.54±3.29)years.Images and videos of standing up and walking,walking side shot,squatting and supine kneeling were taken with smart phones before operation and 6 weeks after operation.The human posture estimation framework OpenPose were used to analyze stride frequency,step length,step length,step speed,active knee knee bending angle,stride length,double support phase time,as well as maximum hip flexion angle and maximum knee bending angle on squatting position.Western Ontario and McMaster Universities(WOMAC)arthritis index and Knee Society Score(KSS)were used to evaluate clinical efficacy of knee joint.Results All patients were followed up for 5 to 7 weeks with an average of(6.00±0.57)weeks.The total score of WOMAC decreased from(64.85±11.54)before op-eration to(45.81±7.91)at 6 weeks after operation(P＜0.001).The total KSS was increased from(101.19±9.58)before opera-tion to(125.50±10.32)at 6 weeks after operation(P＜0.001).The gait speed,stride frequency and stride length of the affected side before operation were(0.32±0.10)m·s-1,(96.35±24.18)steps·min-1,(0.72±0.14)m,respectively;and increased to(0.48±0.11)m·s 1,(104.20±22.53)steps·min-1,(0.79±0.10)m at 6 weeks after operation(P＜0.05).The lower limb support time and active knee bending angle decreased from(0.31±0.38)sand(125.21±11.64)° before operation to(0.11±0.04)s and(120.01±13.35)° at 6 weeks after operation(P＜0.05).Eleven patients could able to complete squat before operation,13 patients could able to complete at 6 weeks after operation,and 9 patients could able to complete both before operation and 6 weeks after operation.In 9 patients,the maximum bending angle of crouching position was increased from 76.29° to 124.11° before operation to 91.35° to 134.12° at 6 weeks after operation,and the maximum bending angle of hip was increased from 103.70° to 147.25° before operation to 118.61° to 149.48° at 6 weeks after operation.Conclusion Gait analysis technology based on artificial intelligence image recognition is a safe and effective method to quantitatively identify the changes of pa-tients'gait.Knee pain of KOA was relieved and the function was improved,the supporting ability of the affected limb was im-proved after TKA,and the patient's stride frequency,stride length and stride speed were improved,and the overall movement rhythm of both lower limbs are more coordinated.

Objective:To explore the changes of mRNA N6-methyladenosine methylation level and methyltransferase-like 3 (METTL3) and demethylase fat mass and obesity-associated (FTO) in the blood of patients with Alzheimer's disease (AD) compared with normal controls.Methods:From January 2020 to June 2021, totally 40 AD patients treated in the outpatient and inpatient department of Neurology of the Affiliated Hospital of Jining Medical University were selected as the patient group, and 40 healthy volunteers as the control group. The blood samples were collected to extract plasma and peripheral blood mononuclear cells for enzyme-linked immunosorbent assay (ELISA), Western blot (WB), quantitative real-time PCR (qPCR) and m6A methylation quantification experiments respectively to detect the methylation levels of METTL3, FTO and m6A. The data were analyzed by SPSS 23.0 statistical software for t-test. Results:The plasma concentrations of METTL3 and FTO protein in AD group were lower than those in control group (METTL3: (22.33±3.01)ng/mL, (25.63±1.70)ng/mL, t=6.055, P<0.01; FTO: (63.51±4.95)pg/mL, (69.60±4.60)pg/mL, ( t=5.704, P<0.01). The band gray values of METTL3 and FTO protein in blood cells in AD group were lower than those in control group (METTL3: 0.399 5±0.028 7, 0.676 6±0.053 3, t=7.935, P=0.001; FTO: 0.439 4±0.017 8, 0.782 6±0.087 6, t=6.652, P=0.003). The expression levels of METTL3 and FTO in blood cell RNA in AD group were lower than those in control group (METTL3: 0.387 8±0.020 3, 1.010 0±0.177 0, t=6.041, P=0.004; FTO: 0.442 8±0.037 1, 1.003 0±0.090 4, t=9.931, P=0.001). The levels of m6A in blood cell RNA in AD group were lower than those in control group((0.000 571±0.000 167)%, (0.002 514±0.001 284)%, t=6.041, P=0.004). Conclusion:The levels of METL3, FTO and m6A methylation are down-regulated in the plasma and peripheral blood mononuclear cells of patients with AD, indicating that there is a certain association between mRNA N6-methyladenosine methylation and AD.

Objective: To investigate the current situation of influenza vaccination, vaccination willingness, recommended behavior and influencing factors of health care workers (HCWs) under the policy of free vaccination. Methods: A cross-sectional survey was conducted among 3 167 medical staff from 8 hospitals in Nanshan district of Shenzhen city based on a web-based questionnaire platform. The logistic regression was used to analyze the data. Results: The influenza vaccination rate in HCWs was 23.97%, and the recommendation rate was 25.69% from 2019 to 2020. Staff with high professional titles, high academic qualifications, and positive awareness about influenza vaccine had a higher vaccination rate. The main reasons for not recommending influenza vaccine were the fear of patients' misunderstanding of commercial benefits, fear of possible disputes caused by recommended vaccination, lack of national or institutional requirements for recommended influenza vaccine, and fear of adverse reactions of influenza vaccines. Conclusion: Under the free policy, the influenza vaccination rate and recommendation rate of HCWs in Nanshan district of Shenzhen city are relatively low. Strengthening health education on influenza and related knowledge, publicizing the policy of free influenza vaccination, providing convenient vaccination services and promoting the construction of relevant policies and regulations are the key to improve the influenza vaccination rate and recommendation rate among HCWs.

Arthropod-borne diseases, such as malaria and dengue fever, have frequently beset five countries(Cambodia, Vietnam, Laos, Myanmar, and Thailand) in the tropical rainy Lancang-Mekong region, which pose a huge threat to social production and daily life. As a resort to such diseases, chemical drugs risk the resistance in plasmodium, non-availability for dengue virus, and pollution to the environment. Traditional medicinal plants have the multi-component, multi-target, and multi-pathway characteristics, which are of great potential in drug development. Exploring potential medicinals for arthropod-borne diseases from traditional medicinal plants has become a hot spot. This study summarized the epidemiological background of arthropod-borne diseases in the Lancang-Mekong region and screened effective herbs from the 350 medicinal plants recorded in CHINA-ASEAN Traditional Medicine. Based on CNKI, VIP, and PubMed, the plants for malaria and dengue fever and those for killing and repelling mosquitoes were respectively sorted out. Their pharmacological effects and mechanisms were reviewed and the material basis was analyzed. The result is expected to serve as a reference for efficient utilization of medicinal resources, development of effective and safe drugs for malaria and dengue fever, and the further cooperation between China and the other five countries in the Lancang-Mekong region.

【Objective】The aim of this study was to investigate the associations between serum complement C3，C4 and low density lipoprotein cholesterol（LDL- C）levels and early- onset coronary heart disease.【Methods】We enrolled 255 cases of coronary angiography confirmed coronary artery disease from January 2018 to September 2018. All the patients were divided into early- onset coronary heart disease group（108 cases）and late- onset coronary heart disease group（147 cases）. Besides ，100 healthy subjects were enrolled and used as controls. Serum levels of C3 ，C4 and LDL-C were analyzed by automatic biochemical analyzer.【Results】Levels of serum C3，C4 and LDL-C in early-onset coronary heart disease group，late-onset coronary heart disease group and healthy control group were significantly different（P < 0.05）. In early-onset coronary heart disease group，C3 and C4 were positively correlated with LDL-C（P < 0.05）. However ，there was no significant correlation （P > 0.05） between C3 ，C4 and LDL- C in late- onset coronary heart disease group and healthy control group.【Conclusions】The levels of C3 and C4 were positively correlated with LDL-C only in the early-onset coronary heart disease patients.
