ObjectiveTo analyze the annual publication volume， prolific research institutions， and research hotspots in the field of shared decision-making （SDM） by utilizing CiteSpace software based on a literature review， predicting the future research focus and development direction in this area. MethodsAn advanced search was conducted in the China National Knowledge Infrastructure （CNKI） and the Web of Science Core Collection databases， with the search timeframe limited to 2004—2024. Scientific knowledge mapping analysis was performed using CiteSpace software. ResultsFrom 2004 to 2024， the volume of publications on SDM research has shown an increasing trend both domestically and internationally. In China， SDM research was mainly focused on nursing， oncology， and other fields， whereas internationally， the emphasis was on patient participation， risk communication， and the application of decision-making support tools. In China， research institutions were primarily nursing schools and specific departments in affiliated hospitals， while internationally， SDM research was concentrated in North America. Keyword analysis showed that the research hotspots in China have gradually shifted from technical topics such as decision-making trees to the practical application of patient participation and decision-making support tools， while international research has earlier moved into the areas of SDM and artificial intelligence-supported decision-making tools. ConclusionThe research hotspots of SDM， both domestically and internationally， have gradually shifted from theoretical exploration to clinical practice and technological applications. In the future， with the deeper integration of artificial intelligence and big data technologies， SDM research in China will focus more on optimizing decision-making support systems and enhancing patient participation. Promoting the localization of SDM practices， fostering multidisciplinary collaboration， and strengthening policy support will be key directions for future research.

OBJECTIVE: To investigate of effectiveness of free fascia lata flap assisted by indocyanine green angiography (ICGA) in treatment of Myerson type Ⅱ and Ⅲ chronic Achilles tendon ruptures. METHODS: A clinical data of 14 patients with Myerson type Ⅱ and Ⅲ chronic Achilles tendon ruptures between March 2020 and June 2024 was retrospectively analyzed. All Achilles tendon defects were repaired with the free fascia lata assisted by ICGA during operation. There were 12 males and 2 females with an average age of 45.4 years (range, 26-71 years). The causes of Achilles tendon rupture included sports injury in 10 cases, Achilles tendon-related tendinopathy in 3 cases, and glass laceration injury in 1 case. The time from Achilles tendon rupture to operation was 4-40 weeks (median, 4.5 weeks). Preoperative MRI examination showed that the defect length of the Achilles tendon was 2-5 cm (mean, 3.2 cm). The operation time and intraoperative blood loss were recorded. The color Doppler ultrasound (CDU) and MRI were taken to observe the foot blood vessels and the tendon healing. The visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) score, Achilles Tendon rupture score (ATRS), and range of motion of the ankle joint were used to estimate the pain and function of ankle joint. RESULTS: All operations of the 14 patients were successfully completed. The operation time ranged from 3.00 to 4.50 hours (mean, 3.60 hours). The intraoperative blood loss ranged from 10 to 50 mL (mean, 36.4 mL). After operation, 1 patient had exudation at the recipient site, which healed after dressing change; the other incisions healed by first intention. All incisions at the donor sites healed by first intention. All patients were followed up 6-36 months (mean, 11.4 months). The CDU of the foot at 1 month after operation showed that the blood flow signal of the perforating vessels of the fascia lata flap was clear. The ankle MRI at 2 months after operation showed the good continuity of the Achilles tendon. No complication such as the Achilles tendon re-rupture, ankle stiffness, or scar contracture occurred during follow-up. Compared with preoperative score, the AOFAS score, ATRS score, and plantar flexion range of motion significantly increased at 1, 3, and 6 months after operation ( P<0.05), while the VAS score and dorsiflexion range of motion significantly decreased ( P<0.05). The AOFAS score, ATRS score, and VAS score at 3 and 6 months further improved when compared with those at 1 month ( P<0.05); however, there was no significant difference in the range of motion of the ankle joint ( P>0.05). There was no significant difference in above indicators between 3 and 6 months after operation ( P>0.05). CONCLUSION The treatment of Myerson type Ⅱ and Ⅲ chronic Achilles tendon ruptures with free fascia lata flaps under the guidance of ICGA has the advantages of precise design, fast healing, and a wide range of adaptability.

OBJECITVE: To investigate the effectiveness of three-dimensional (3D) printing-assisted vascularized fibular graft for repairing metatarsal defects. METHODS: Between November 2021 and February 2024, 11 patients with varying degrees of metatarsal defects caused by trauma were treated. There were 10 males and 1 female, aged 22-67 years, with a mean age of 51.2 years. The defect locations were as follows: the first metatarsal in 4 cases, the fifth metatarsal in 2 cases, the first and the second metatarsals in 1 case, the first to third metatarsals in 1 case, the third and the fourth metatarsals in 1 case, the third to fifth metatarsals in 1 case, and the first to fifth metatarsals in 1 case. The preoperative American Orthopaedic Foot & Ankle Society (AOFAS) score was 67.0 (48.5, 72.5). Based on 3D-printed bilateral feet models and mirrored healthy-side foot arch angles for preoperative planning and design, the vascularized fibular graft was performed to repair the metatarsal defects. At last follow-up, the medial and lateral longitudinal arches of bilateral feet were measured on weight-bearing X-ray films, and functional assessment was conducted using the AOFAS score. RESULTS: All operations were successfully completed, with an operation time ranging from 180 to 465 minutes (mean, 246.8 minutes). All incisions healed by first intention, with no occurrence of osteomyelitis. All patients were followed up 6-22 months (mean, 10 months). X-ray film reviews showed bone graft healing in all cases, with a healing time of 3-6 months (mean, 5 months). All patients underwent internal fixator removal at 6-12 months after operation. At last follow-up, no significant difference was observed in the medial and lateral longitudinal arches between the healthy and affected feet ( P>0.05). The AOFAS score of the affected foot was 78.0 (73.5, 84.0), showing a significant improvement compared to the preoperative score ( P<0.05). The effectiveness was rated as excellent in 1 case, good in 7 cases, fair in 2 cases, and poor in 1 case. Linear scarring remained at the donor site, with no functional impairment in adjacent joint movement. CONCLUSION 3D printing-assisted vascularized fibular graft for repairing metatarsal defects can effectively restore the physiological angle of the foot arch, facilitate the recovery of weight-bearing alignment, promote good bone healing, and yield satisfactory clinical outcomes.

Autophagy is a fundamental biological metabolic process involved in immune defense, material metabolism, and homeostasis and closely linked to immune regulation. Systemic lupus erythematosus (SLE) is a widespread connective tissue disorder primarily resulting from immune system imbalance. Due to the immune system's failure to recognize its own substances, it generates autoantibodies that can affect various tissues and organs, leading to diverse clinical manifestations. The pathogenesis and treatment of SLE are currently under extensive investigation. In normal metabolic processes, autophagy engages in both innate and adaptive immunity, regulates the immune response, and is crucial for maintaining normal immune function and the body's internal homeostasis. Research has indicated that SLE patients exhibit immune dysfunction and altered autophagy levels. Modulating autophagy expression can influence immune system functionality and alleviate SLE symptoms. Additionally, autophagy aids in the innate immune response and adaptive immunity by clearing metabolites and regulating the life cycle of immune cells. Studies suggest that drugs targeting autophagy can positively influence the progression of SLE. This article reviews advancements in research regarding the impact of autophagy on the pathogenesis of SLE through the regulation of immune system functions.

OBJECTIVES: To investigate the protective effect of Yiqi Yangyin Huazhuo Tongluo Formula (YYHT) against high glucose-induced injury in mouse renal podocytes (MPC5 cells) and the possible mechanism. METHODS: Adult Wistar rats were treated with 19, 38, and 76 g/kg YYHT or saline via gavage for 7 days to prepare YYHT-medicated or blank sera for treatment of MPC5 cells cultured in high glucose (30 mmol/L) prior to transfection with a miR-21a-5p inhibitor or a miR-21a-5p mimic. The changes in miR-21a-5p expressions and the mRNA levels of FoxO1, PINK1, and Parkin in the treated cells were detected with qRT-PCR, and the protein levels of nephrin, podocin, FoxO1, PINK1, and Parkin were detected with Western blotting. Autophagic activity in the cells were evaluated with MDC staining. The effect of miR-21a-5p mimic on FoxO1 transcription and the binding of miR-21a-5p to FoxO1 were examined with luciferase reporter gene assay and radioimmunoprecipitation assay. RESULTS: MPC5 cells exposed to high glucose showed significantly increased miR-21a-5p expression, lowered expressions of FoxO1, PINK1, and Parkin1 mRNAs, and reduced levels of FoxO1, PINK1, parkin, nephrin, and podocin proteins and autophagic activity. Treatment of the exposed cells with YYHT-medicated sera and miR-21a-5p inhibitor both significantly enhanced the protein expressions of nephrin and podocin, inhibited the expression of miR-21a-5p, increased the mRNA and protein expressions of FoxO1, PINK1 and Parkin, and upregulated autophagic activity of the cells. Transfection with miR-21a-5p mimic effectively inhibited the transcription of FoxO1 and promoted the binding of miR-21a-5p to FoxO1 in MPC5 cells, and these effects were obviously attenuated by treatment with YYHT-medicated sera. CONCLUSIONS YYHT-medicated sera alleviate high glucose-induced injury in MPC5 cells by regulating miR-21a-5p/FoxO1/PINK1-mediated mitochondrial autophagy.

OBJECTIVES: To explore the association of the expression of WW domain-containing ubiquitin E3 ligase 1 (WWP1) with immune infiltration in tumor microenvironment (TME) of ovarian cancer. METHODS: Ovarian cancer patient data from The Cancer Genome Atlas (TCGA) were used to analyze the association of WWP1 expression with patient prognosis. TISCH2 was utilized to analyze the changes in immune cell subtypes in TME of metastatic tumor and after chemotherapy. The impact of WWP1 on immune cell infiltration, somatic copy number alterations of WWP1 and evolution of immune cell subtypes was evaluated using TIMER and TIGER pseudo-time analysis. A deep learning model was used to analyze TCGA pathological images to investigate the effect of WWP1 on TME of ovarian cancer. RNA-seq analysis was conducted to identify the differentially expressed genes in WWP1-overexpressing SKOV3 cells and validate immune infiltration. Multicolor immunofluorescence assay was used to analyze the immune markers in SKOV3 and SKOV3/DDP cell xenografts in nude mice. RESULTS: The patients with high WWP1 expression levels had significantly lower overall survival rate (P=0.0012). High WWP1 expression levels and Stage IV disease were both associated with a poor prognosis (P<0.05). In metastatic ovarian cancer or after chemotherapy, the percentages of malignant tumor cells and tumor-associated fibroblasts increased in the TME, accompanied by elevated WWP1 levels. WWP1 expression level was positively correlated with pro-tumorigenic immunosuppressive cells (r=0.1323-0.3955, P<0.05) and negatively with tumor-inhibiting immune cells (r=-0.1949- -0.1333, P<0.05). Specific copy number alterations of WWP1 also influenced CD8⁺ T cell percentage and neutrophil infiltration levels in the TME. RNA-seq analysis of WWP1-overexpressing SKOV3 cells and immunofluorescence assay of the tumor-bearing mice yielded findings consistent with those of bioinformatics analysis. CONCLUSIONS WWP1 may serve as a prognostic biomarker and a potential target for immune regulation in the TME of ovarian cancer.

Cholesterol (CH) plays a crucial role in enhancing the membrane stability of drug delivery systems (DDS). However, its association with conditions such as hyperlipidemia often leads to criticism, overshadowing its influence on the biological effects of formulations. In this study, we reevaluated the delivery effect of CH using widely applied lipid microspheres (LM) as a model DDS. We conducted comprehensive investigations into the impact of CH on the distribution, cell uptake, and protein corona (PC) of LM at sites of cardiovascular inflammatory injury. The results demonstrated that moderate CH promoted the accumulation of LM at inflamed cardiac and vascular sites without exacerbating damage while partially mitigating pathological damage. Then, the slow cellular uptake rate observed for CH@LM contributed to a prolonged duration of drug efficacy. Network pharmacology and molecular docking analyses revealed that CH depended on LM and exerted its biological effects by modulating peroxisome proliferator-activated receptor gamma (PPAR-γ) expression in vascular endothelial cells and estrogen receptor alpha (ERα) protein levels in myocardial cells, thereby enhancing LM uptake at cardiovascular inflammation sites. Proteomics analysis unveiled a serum adsorption pattern for CH@LM under inflammatory conditions showing significant adsorption with CH metabolism-related apolipoprotein family members such as apolipoprotein A-V (Apoa5); this may be a major contributing factor to their prolonged circulation in vivo and explains why CH enhances the distribution of LM at cardiovascular inflammatory injury sites. It should be noted that changes in cell types and physiological environments can also influence the biological behavior of formulations. The findings enhance the conceptualization of CH and LM delivery, providing novel strategies for investigating prescription factors' bioactivity.

Objective:To analyze the epidemiological characteristics of human respiratory syncytial virus (HRSV) in cases of febrile respiratory syndrome in China from 2010 to 2020.Methods:Based on the sub-project of the National Science and Technology Major Project for Infectious Disease Prevention and Control "Infectious Disease Monitoring Technology Platform", active monitoring of febrile respiratory syndrome cases was conducted in sentinel hospitals in 31 provinces across China (excluding Hong Kong, Macau, and Chinese Taiwan) from January 2010 to December 2020, resulting in the inclusion of 191 441 cases. Clinical specimens of monitored cases were screened for HRSV nucleic acid, and the differences in HRSV detection rates among different age groups, regions, and time periods were analyzed using the χ 2 test/Fisher exact probability method. Results:Among the 191 441 cases of febrile respiratory syndrome in China from 2010 to 2020, the age group M ( Q1, Q3) was 9 (2, 40) years old, with 83 773 cases (43.8%) in the <5 years old group. There were 113 660 males, with a male-to-female ratio of 1.5∶1.0. There were as many as 105 508 cases (55.2%) of scattered children and preschool children. About 70 565 cases (36.9%) lived in the northern region. There were 13 858 HRSV positive cases, with a total positive rate of 7.2%. The positive rate of HRSV detection in the northern population was 5.7% (4 004/70 565), which was lower than that in the southern population (8.2%, 9 854/120 876), and the difference was statistically significant (χ 2=407.4, P<0.001). HRSV was detected in all age groups, with the highest positive rate of 23.9% in the <6 months age group. The month with the highest positive rate was December, and autumn and winter were the main epidemic seasons. Both northern and southern HRSV subtypes were mainly infected with type A, with a low proportion of mixed infections of type A and type B. Conclusion:HRSV is a common pathogen causing respiratory infections in children from 2010 to 2020. It can be detected throughout the year and shows the main peak of prevalence in autumn and winter. The HRSV strain is mainly classified as a type A infection.

Objective:To evaluate the prognosis of patients with primary thyroid malignant lymphoma (PTL) treated with total thyroidectomy alone or in combination with R-CHOP chemotherapy, and analyze the factors influencing their prognosis.Methods:A retrospective analysis was conducted on 62 patients with PTL admitted to the Hematology Department of Shanxi Provincial Cancer Hospital from Jan. 2009 to Jan. 2020. The patients were with an average age of (63.51±9.83) years, with 20 males and 42 females. According to Ann Arbor staging and patients' wishes, 10 cases received simple thyroidectomy, 47 cases received total thyroidectomy +R-CHOP, and 5 cases received total thyroidectomy +R-CHOP+ radiotherapy. After 3 months of treatment, the short-term curative effect was collected. According to the prognosis of patients after 24 months of follow-up, the dead cases were classified into bad group and the surviving cases into good group. Single factor and LASSO regression dimensionality reduction were used to screen the influencing factors, and Logistic regression analysis was used to analyze the influencing factors of PTL prognosis.Results:Among 62 patients with PTL, 21 (33.87%) had complete response (CR), 27 (43.55%) had partial response (PR), 9 (14.52%) had stable disease (SD), and 5 (8.06%) had progressive disease (PD). After a follow-up of 24 months, the mortality rate among 10 patients who underwent surgical treatment alone was 90% (9/10), the mortality rate among those who underwent surgical treatment combined with R-CHOP therapy was 19.15% (9/47) ,18 deaths were categorized as having a poor prognosis, while 44 survivors were classified as having a favorable prognosis.Univariate, LASSO regression screening, and Logistic regression analysis showed that Ann Arbor staging ( OR=5.105), pathological type ( OR=3.622), international prognostic index (IPI) score ( OR=2.709), treatment method ( OR=0.730), hemoglobin ( OR=0.392), and lactate dehydrogenase (LDH) ( OR=6.469) were factors affecting the prognosis of PTL (all P<0.05) . Conclusions:The combined use of total resection and R-CHOP treatment for patients has a superior prognosis compared to patients undergoing total resection alone. Furthermore, the prognosis of patients is also influenced by factors such as Ann Arbor staging and IPI scoring. Based on this, clinical care plans can be refined to improve the prognosis.
