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 explore the molecular mechanism by which SOS Ras/Rac guanine nucleotide exchange factor 1-intronic transcript 1(SOS1-IT1)affects enhancer of zeste homolog 2(EZH2)protein expression in endometrial cancer cells Ishikawa and RL95-2.Methods Lentiviral transfection of short hairpin RNA(shRNA)and overexpression plasmid were used in Ishikawa and RL95-2 cell lines to knock down and overexpress SOS1-IT1.The mechanism of EZH2 expression regulation was studied using Real-time PCR,Western blotting,and chromatin immunoprecipitation.Results The expression of SOS1-IT1 and EZH2 genes was positively correlated in endometrial cancer tissues.Knocking down SOS1-IT1 significantly reduces the expression of EZH2,inhibited the proliferation and migration of Ishikawa and RL95-2 cells,and could reduced the acetylation of histone H3 at position 27(H3K27)and the enrichment of CREB binding protein(CBP)in the EZH2 gene promoter region.Overexpression of SOS1-IT1 could increased the expression of EZH2 and enhance the acetylation of H3K27 and the enrichment of CBP.CBP could bind to SOS1-IT1 RNA,and this binding ability was weakened when CBP was knocked down.Conclusion SOS1-IT1 can promote the expression level of EZH2 in endometrial cancer cells Ishikawa and RL95-2 by regulating the acetylation modification level of the EZH2 gene promoter region,thereby affecting the proliferation and migration ability of endometrial cancer cells.

Objective:To summarize the technical difficulties, key points and cosmetic effects of Ti-loop patch application in breast shaping of immediate reconstruction with omental flap transplantation after mastectomy.Methods:The clinical data of 90 cases with breast cancer who underwent immediate breast reconstruction by using laparoscopically harvested omental flap alone or combined with prosthesis after nipple and areola complex sparing mastectomy from May. 2020 to Jan. 2023 in Hunan Cancer Hospital was retrospectively analyzed. All patients were female between 16 and 55 years old with the average age of 42. Their courses of the disease range from 5 to 26 months with the mean of 15.5 months. These patients received mastectomy with conservation of nipple and areola, and then the greater omentum with right pedicle were harvested laparoscopically. Ti-loop patch was used to hang and fix the greater omentum as a support. 27 patients accepted immediate breast reconstruction with pedicled greater omentum alone, while 63 subjects with greater omentum and gel prosthesis. Among them, contralateral breast contraction and lift was operated on 9 cases.Results:All the pedicled greater omentum successfully survived, and wound surfaces of donor and recipient sites healed at stage I. Axillary lymph node dissection and postoperative radiotherapy were performed on 14 patients with positive pathological examination of sentinel lymph nodes. Breasts of two patients were found to be smaller after postoperative radiotherapy. All 90 subjects were followed up for 5 to 32 months, and the average follow-up period was 16.4 months. The reconstructed breasts were good in shape and tactile sensation. Only punctate scars were observed in donor sites of abdomen. All patients recovered with no upper limb lymphedema, no short and long term complications in abdomen, and only one patient had papillary recurrence without distant metastasis.Conclusions:The omental flap is hard to be sutured and shaped in the reconstructed breast, while easily to be avulsed and form hematoma. The application of Ti-loop patch, which could semi-surround and wrap the greater omentum, and suspend and fix it on the chest wall in upper pole of the breast as a support, can significantly improve the reconstruction effect.

Objective To develop a home skin care guidance scheme for newborns,and initially implement it to reducing the risk of skin-related issues.Methods Searching both domestic and international databases,we identified relevant literature.Following a quality evaluation,evidence integration,and group discussions,we developed the con-tent of the home skin care guidance for newborns.Subsequently,we refined this content through 2 rounds of expert consultations to finalize the scheme.To initially implement the scheme,we conveniently selected 20 healthy new-borns born between August 1st and 15th,2024,at a tertiary-level comprehensive hospital in Fujian Province as an experimental group.Their parents received skin care guidance based on our scheme via a WeChat platform.In contrast,we selected another group of 20 healthy newborns delivered between July 1st and 15th,2024,at the same hospital as a control group;their parents were provided with conventional skin care guidance.We compared the in-cidence rates of diaper dermatitis and eczema between these 2 groups of newborns at a month of age.Results A total of 33 experts from 30 tertiary hospitals across 19 provinces(including autonomous regions and municipalities)were invited to participate in a questionnaire survey.The response rates for both rounds of expert questionnaires reached 100％.The authority coefficients for the experts were recorded at 0.78 and 0.83,while the Kendall concor-dance coefficients were found to be 0.188 and 0.142(all P＜0.001).The final newborn home skin care guidance scheme consists of 6 first-level items,41 second-level items,such as the selection of newborn care products,methods for neonatal bathing and prevention of neonatal diaper dermatitis,and so on.Preliminary application results indicated that the incidence of diaper dermatitis in the experimental group was significantly lower than that observed in the control group,with a statistically significant difference noted(P=0.047).There was no significant difference in the incidence of eczema between the 2 groups at the age of a month(P=0.201).Conclusion The Neonatal Home Skin Care Guidance Scheme for newborns has been demonstrated to be scientific,reliable and feasible.The implementa-tion of this scheme has proven beneficial in reducing the incidence of diaper dermatitis at a month of age.Howev-er,the sample size needs to be expanded to further verify its implementation effect.

Microfluidic chips have revolutionized analytical sciences through miniaturization and high-throughput capabilities.However,conventional static devices are constrained by fixed architectures,functional rigidity,and high customization costs.In recent years,,the emerging configurable and reconfigurable microfluidic technologies have provided solutions for these limitations through dynamic adaptability.Configurable systems enable post-fabrication customization via modular assembly or boundary modification,offering cost-effective functional versatility.Reconfigurable microfluidics represents a more advanced paradigm,incorporating real-time decision-making and dynamic control through physical/virtual boundary adjustments during operation.These adaptive systems enable precise manipulation of microenvironments for applications ranging from single-cell manipulation to dynamic biochemical synthesis.In this review,a ″static-dynamic boundary″ framework to systematically analyze both technologies was proposed,and the design rationales,operational mechanisms,and implementation strategies were compared.The development history of these two techniques was introduced,and the applications demonstrated their transformative potential in developing intelligent lab-on-chip systems,while technical challenges in standardization and control interfaces were critically assessed.The development trend on integrating smart materials and AI-driven automation to advance next-generation adaptive microfluidic platforms was prospected.

PURPOSE: To investigate the pathological changes of the synovium in mice with post-traumatic osteoarthritis (PTOA) treated with 4-octyl itaconate (4-OI) and evaluate the therapeutic effects of 4-OI. METHODS: In the phenotypic validation experiment, the mice were randomly divided into 3 groups: wild-type (WT) group, sham group, and destabilization of the medial meniscus (DMM) group. Through MRI, micro-CT, and histological analysis, it was determined that the DMM surgery induced a mouse PTOA model with significant signs of synovitis. At 12 weeks post-DMM surgery, synovial tissues from the DMM group and WT group mice were collected for ribonucleic acid sequencing analysis. In the 4-OI treatment experiment, mice were randomly divided into the sham group, DMM group, DMM + 4-OI (50 mg/kg) group, and DMM + 4-OI (100 mg/kg) group. Von Frey tests and open field tests were conducted at intervals during the 12 weeks following the DMM surgery. After 12 weeks of surgery, the efficacy of 4-OI treatment on PTOA in mice was evaluated using MRI, micro-CT, histological analysis, and quantitative real-time polymerase chain reaction. Finally, we utilized network pharmacology analysis to predict the mechanism of 4-OI in treating PTOA synovitis and conducted preliminary validation. Statistical analysis was performed using one-way ANOVA and the Kruskal-Wallis test. Difference was considered statistically significant at p < 0.05. RESULTS: The DMM surgery effectively induced a PTOA mouse model, which displayed significant symptoms of synovitis. These symptoms included a notable increase in both the number of calcified tissues and osteophytes (p < 0.001), an enlargement of the calcified meniscus and synovial tissue volume (p < 0.001), and thickening of the synovial lining layer attributable to M1 macrophage accumulation (p = 0.035). Additionally, we observed elevated histological scores for synovitis (p < 0.001). Treatment with 4-OI inhibited the thickening of M1 macrophages in the synovial lining layer of PTOA mice (p < 0.001) and reduced fibrosis in the synovial stroma (p = 0.004). Furthermore, it reduced the histological scores of knee synovitis in PTOA mice (p = 0.006) and improved the inflammatory microenvironment associated with synovitis. Consequently, this treatment alleviated pain in PTOA mice (p < 0.001) and reduced spontaneous activity (p = 0.003). Bioinformatics and network pharmacology analyses indicated that 4-OI may exert its therapeutic effects by inhibiting the differentiation of synovial Th17 cells. Specifically, compared to the lipopolysaccharide stimulation group, 4-OI reduced the levels of positive regulatory factors of Th17 cell differentiation (IL-1: p < 0.001, IL-6: p < 0.001), key effector molecules (IL-17A: p < 0.001, IL-17F: p = 0.004), and downstream effector molecules in the IL-17 signaling pathway (CCL2: p < 0.001, MMP13: p < 0.001). CONCLUSION 4-OI is effective in inhibiting synovitis in PTOA, thereby alleviating the associated painful symptoms.

This study primarily aimed to investigate the prevalence of human papillomavirus (HPV) and other common pathogens of sexually transmitted infections (STIs) in spermatozoa of infertile men and their effects on semen parameters. These pathogens included Ureaplasma urealyticum, Ureaplasma parvum, Chlamydia trachomatis, Mycoplasma genitalium , herpes simplex virus 2, Neisseria gonorrhoeae, Enterococcus faecalis, Streptococcus agalactiae, Pseudomonas aeruginosa , and Staphylococcus aureus . A total of 1951 men of infertile couples were recruited between 23 March 2023, and 17 May 2023, at the Department of Reproductive Medicine of The First People's Hospital of Yunnan Province (Kunming, China). Multiplex polymerase chain reaction and capillary electrophoresis were used for HPV genotyping. Polymerase chain reaction and electrophoresis were also used to detect the presence of other STIs. The overall prevalence of HPV infection was 12.4%. The top five prevalent HPV subtypes were types 56, 52, 43, 16, and 53 among those tested positive for HPV. Other common infections with high prevalence rates were Ureaplasma urealyticum (28.3%), Ureaplasma parvum (20.4%), and Enterococcus faecalis (9.5%). The prevalence rates of HPV coinfection with Ureaplasma urealyticum, Ureaplasma parvum, Chlamydia trachomatis, Mycoplasma genitalium , herpes simplex virus 2, Neisseria gonorrhoeae, Enterococcus faecalis, Streptococcus agalactiae , and Staphylococcus aureus were 24.8%, 25.4%, 10.6%, 6.4%, 2.4%, 7.9%, 5.9%, 0.9%, and 1.3%, respectively. The semen volume and total sperm count were greatly decreased by HPV infection alone. Coinfection with HPV and Ureaplasma urealyticum significantly reduced sperm motility and viability. Our study shows that coinfection with STIs is highly prevalent in the semen of infertile men and that coinfection with pathogens can seriously affect semen parameters, emphasizing the necessity of semen screening for STIs.

Objective:To explore the risk assessment and intervention effect of WeChat platform-based health management in high-risk populations for cardiovascular diseases (CVD).Methods:It was a randomized controlled trial. A total of 480 individuals at high risk of CVD who underwent physical examinations at the Health Management Center of Sichuan Provincial People′s Hospital from February to April in 2023 were selected using a simple random sampling method. The participants were randomly assigned to either the intervention group or the control group (240 cases each) using a random number table. The control group received routine follow-up and health assessments, while the intervention group received an additional 12-month WeChat-based health management intervention. During the study, 28 participants were lost to follow-up, resulting in 227 participants in the intervention group and 225 in the control group being included in the final analysis. The 10-year CVD risk was assessed using the prediction for atherosclerotic cardiovascular disease risk in China (China-PAR) model, and psychological status was evaluated using the self-rating anxiety Scale (SAS) and the self-rating depression scale (SDS). Changes in health behaviors, adherence, life style, blood pressure, metabolic indicators, psychological status, and CVD risk were compared before and after the intervention in both groups to evaluate the intervention′s effectiveness.Results:Among the 452 high-risk participants analyzed, the intervention group included 227 individuals [mean age: (53.16±10.81) years; 117 males and 110 females], and the control group included 225 individuals [mean age: (52.60±10.25) years; 118 males and 107 females]. There was no significant differences in baseline characteristics between the two groups (all P>0.05). After 12 months of intervention, the intervention group showed significant improvements in medication adherence, intake of vegetables and fruits, exercise duration, sleep time, proportion of regular lifestyle, and high density lipoprotein cholesterol (HDL-C) levels, all of which were all higher than both the baseline values and those in the control group (all P<0.05). Conversely, the intervention group showed reductions in medical visit rate, smoking and drinking rates, high-salt diet, meat intake, body mass index (BMI), fasting blood glucose, systolic and diastolic blood pressure, low density lipoprotein cholesterol (LDL-C), total cholesterol, triglycerides, SAS and SDS scores when compared to the baseline values and those in the control group (all P<0.05). The proportions of participants with 10-year CVD risk levels of 10%-<20%, 20%-<30%, 30%-<40%, and ≥40% significantly decreased in the intervention group after intervention (18.94% vs 36.12%, 12.78% vs 26.43%, 7.93% vs 19.82%, 3.96% vs 17.63%), and were also significantly lower than those in the control group (18.94% vs 40.45%, 12.78% vs 30.67%, 7.93% vs 22.67%, 3.96% vs 16.89%) (all P<0.001). After 12 months, the intervention group showed significantly higher improvement rates in both medication adherence and non-medication-related compliance behaviors, including smoking, alcohol consumption, meat and salt intake, fruit and vegetable intake, exercise duration, sleep duration, and lifestyle regularity, when compared to those in the control group (16.74% vs -3.11%, 14.54% vs -0.89%, 16.74% vs -0.44%, 57.71% vs 8.44%, 21.15% vs -0.44%, 56.83% vs -6.67%, 51.54% vs -3.56%, 60.79% vs -7.11%, 26.87% vs -13.78%, 22.91% vs -1.78%) (all P<0.001). Conclusion:The WeChat platform-based health management intervention can effectively improve the behavioral patterns, compliance, control of CVD risk factors and psychological status of high-risk populations for CVD, and help reduce their 10-year risk of CVD.

Objective:To explore the impacts of 131I-NaI radiotherapy on the promotion of glycolysis and 18F-fluorodeoxyglucose ( 18F-FDG) uptake in pancreatic cancer cells via the induction of proviral integration moloney murineleukemia virus 2 (PIM2) and 6-phosphofructo-2-kinase/fructose-2, 6-biphosphatase 3 (PFKFB3). Methods:In the cell experiments, human pancreatic carcinoma cells-1 (PANC-1) were randomly divided into four groups: a control group, an HJ-PI01 group, a 131I-NaI group, and an HJ-PI01 + 131I-NaI group. Their aerobic glycolysis capacity was assessed by measuring glucose uptake, lactate production, and extracellular acidification rate (ECAR). In vivo animal experiments, 12 nu/nu female nude mice were given 100 μl (1 × 10 7 cells) of cell suspension through subcutaneous injection into the left lower limbs. When the tumor volume reached approximately 60 mm 3, these mice were divided into four groups (a control group, a HJ-PI01 group, a 131I-NaI group, and an HJ-PI01+ 131I-NaI group) using a random number table, with three mice in each group. After 14 days of treatment, 18F-FDG PET/CT imaging was performed to calculate the maximum standardized uptake value (SUV max) of the xenografts. Following PET/CT imaging, the tumor tissues were harvested and analyzed for PIM2, PFKFB3, and Ki-67 expressions using immunohistochemistry. Results:In cell experiments, compared to the control group, the HJ-PI01 group exhibited significant reduction in glucose uptake, lactate production, PFKFB3 protein expression, and ECAR in PANC-1 cells ( t = 4.59-13.98, P < 0.05). In contrast, the 131I-NaI group showed significant increases in these parameters ( t = 3.36-13.97, P < 0.05). Compared to the 131I-NaI group, the HJ-PI01+ 131I-NaI group showed significant reduction in glucose uptake, lactate production, PFKFB3 protein expression, and ECAR ( t = 5.14-20.87, P < 0.05). In the animal experiments, compared to the control group, the three groups displayed significant decrease in SUV max of 18F-FDG uptake in tumors ( t = 16.48, 22.49, 32.64, P < 0.001). Moreover, the HJ-PI01 + 131I-NaI group exhibite significantly lower SUV max than the 131I-NaI group ( t = 10.16, P < 0.001). Immunohistochemical analysis revealed that the HJ-PI01+ 131I-NaI group, compared to the 131I-NaI group, showed significantly lower Ki-67 expression and the PIM2/PFKFB3 signaling pathway in tumor tissues ( t = 3.27, 10.73, 14.85, P < 0.05). Conclusions:Glycolysis enhancement of PANC-1 cells, mediated by the PIM2/PFKFB3 signaling pathway inhibition, can significantly improve the anticancer capacity of 131I-NaI, providing a novel strategy for radiotherapy in pancreatic cancer.
