Objective To compare the dosimetric differences in the heart and its substructures between two hybrid plans for hypofractionated whole-breast radiotherapy after breast-conserving surgery in patients with early-stage left-sided breast cancer. Methods A total of 46 patients with early-stage left-sided breast cancer who underwent hypofractionated whole-breast radiotherapy were randomly selected. Two hybrid radiotherapy plans were used, including hybrid intensity-modulated radiotherapy (H_IMRT) and hybrid volumetric-modulated arc therapy (H_VMAT). The heart and its substructures were contoured, including left anterior descending (LAD), left ventricle (LV), right coronary artery (RCA), and right ventricle (RV). The heart and substructure doses, as well as monitor units, were compared between H_IMRT and H_VMAT. Results Both hybrid plans met the clinical requirements. H_IMRT significantly outperformed H_VMAT for the heart (V₁₀, V₃₀, and D_mean), LAD (V₃₀, V₄₀, D_max and D_mean), LV (V₁₀, V₂₀ and D_mean), RCA (D_max, D_mean), and RV (V₅, V₁₀, D_mean) (P < 0.001). Additionally, H_IMRT was significantly superior to H_VMAT for heart V₅, LAD V₂₀, and RV V₂₀ (P = 0.005, 0.035 and 0.037). For LAD (V₁₅, V₄₀) and LV (V₅, V₂₅), H_IMRT was slightly better than H_VMAT, and the difference was not statistically significant. Conclusion Both H_IMRT and H_VMAT hybrid radiotherapy plans are suitable for hypofractionated whole-breast radiotherapy after breast-conserving surgery in patients with early-stage left-sided breast cancer. H_IMRT is slightly better than H_VMAT in dose sparing for the heart and its substructures.

Objective: To observe the clinical efficacy and safety of Yiqi Tongluo Decoction in the intervention of early traditional Chinese medicine (TCM) syndromes after ischemic cerebrovascular disease (ICVD) intervention. Methods: From October 2020 to July 2023, a randomized, double-blind, placebo-controlled study was conducted to include 60 patients with qi deficiency, blood stasis, and phlegm obstruction syndrome after ICVD interventional therapy. They were assigned to the Yiqi Tongluo Decoction treatment group (30 cases) and the TCM placebo routine treatment control group (30 cases) according to the randomized block design. Both groups received routine standardized treatment of Western medicine, including dual antiplatelet, lipid regulation, and control of risk factors for cerebrovascular disease. The treatment group was treated with Yiqi Tongluo Decoction based on the control group. The course of treatment was 60 days and follow-up was carried out 2 and 6 months after the operation. The improvement of qi deficiency syndrome, blood stasis syndrome, phlegm syndrome score and TCM syndrome score, modified Rankin score (mRS), Barthel index (BI) score, Fatty acid-binding protein 4 (FABP4) level, incidence of transient ischemic attack (TIA) and ischemic stroke (IS) and incidence of adverse reactions, Head and neck CT angiography (CTA) or digital subtraction angiography (DSA) examination were collected. The clinical efficacy of the patients 2 months after the operation was taken as the main outcome index to preliminarily evaluate the early and long-term efficacy of Yiqi Tongluo Decoction after the ICVD intervention. The early and long-term clinical efficacy and safety of Western medicine standardized treatment combined with TCM Yiqi Tongluo Decoction on patients with qi deficiency, blood stasis and phlegm obstruction syndrome after ICVD intervention were evaluated. The safety of Yiqi Tongluo Decoction in the treatment of patients after ICVD intervention with white blood cell (WBC), C-reactive protein (CRP), fibrinogen (FIB), plasminogen time (PT), recurrence of cerebral ischaemia and restenosis in patients at 2 and 6 months after treatment were evaluated. Results: Compared to the control group, the TCM syndrome scores for qi deficiency, blood stasis and phlegm syndrome in the treatment group reduced significantly, the clinical efficacy improved significantly, the mRS score and FABP4 were reduced, and the BI score was increased. Adverse events such as cerebral ischaemia were fewer in the treatment group than in the control group, but the difference was not statistically significant; levels of CRP, WBC and PT were reduced, and levels of FIB were reduced at 6 months post-treatment, all P<0.01, and images were intuitively compared. The treatment group was superior to the control group. Conclusion Yiqi Tongluo Decoction combined with Western medicine standard treatment can improve the early clinical efficacy of ICVD patients with qi deficiency, blood stasis and phlegm obstruction syndrome after interventional surgery, improve neurological impairment and daily living ability, reduce the state of qi deficiency syndrome, blood stasis syndrome and phlegm syndrome after interventional surgery, and improve the clinical efficacy of TCM. At the same time, it can reduce the level of FABP4, the target of atherosclerosis and restenosis after interventional surgery, reduce the level of inflammation after interventional surgery in patients with ICVD, regulate coagulation function, and reduce the incidence of long-term recurrence of cerebral ischemia after interventional surgery, with good safety.

AIM:To investigate the therapeutic effects of botulinum toxin A(BTXA)injection versus strabismus surgery in the treatment of acute acquired comitant esotropia(AACE).METHODS:Patient records of AACE cases treated at First People's Hospital of Nantong from January 2019 to September 2023 were retrospectively analyzed in this study. Patients were categorized into either strabismus surgery or BTXA injection groups based on treatment modality. Further stratification was performed according to preoperative deviation angles [>35 prism diopters(PD)vs ≤35 PD] and age(≥18 years adult group vs <18 years adolescent group). The baseline patient characteristics were collected, deviation angles at multiple timepoints before and after treatment were measured, and stereopsis test results were documented. Through comparative analysis of therapeutic outcomes across subgroups, we systematically evaluated the efficacy of different treatment approaches.RESULTS:A total of 43 AACE patients were included. At the final follow-up, both the surgery and BTXA injection groups showed a statistically significant decrease in deviation angle compared to pretreatment measurements(P<0.001). Significant differences were noted between the two groups in terms of the cure rate of strabismus and the recovery rate of stereopsis(P<0.05). For patients with deviations >35 PD, surgery yielded significantly better outcomes than injection therapy in postoperative angle, success rate, and stereopsis recovery(P<0.05). Similarly, in patients aged ≥18 years, surgical treatment was superior to injections in reducing strabismus angle, improving success rates, and restoring stereopsis(P<0.05).CONCLUSION:Both BTXA injection and strabismus surgery demonstrate therapeutic efficacy in AACE. Surgical treatment demonstrated superior efficacy compared to BTXA injection therapy, particularly in patients with deviations >35 PD and those aged ≥18 years. For patients with angles ≤35 PD or under 18 years, BTXA injection remains a viable treatment option.

ObjectiveTo investigate the awareness and clinical practice of guidelines for the prevention and treatment of chronic hepatitis B （2022 edition） among clinicians. MethodsFrom July 19 to December 31， 2024， a self-designed electronic questionnaire was distributed via the WeChat mini program to collect related data from 1 588 clinicians nationwide， including their awareness and practice based on 18 questions regarding testing and referral， diagnosis and treatment， and follow-up. ResultsAmong all respondents， only 350 clinicians correctly understood all the updated key points of antiviral indications and treatment for special populations in the 2022 edition of guidelines for the prevention and treatment of chronic hepatitis B， with an overall awareness rate of 22.0%. Only 20% ‍—‍ ‍40% of the patients with positive HBV DNA and an age of >30 years receive antiviral therapy， while 80% ‍—‍ ‍100% of the patients with positive HBV DNA and a family history of hepatitis B cirrhosis or hepatocellular carcinoma receive antiviral therapy. The median follow-up rates at 1 year， 3 years， and 5 years were 67.5% 57.5% and 47.5%，respectively， showing a trend of gradual reduction， which might be associated with the influencing factors such as insufficient time for follow-up management by clinicians， insufficient awareness of the disease among patients， and poor adherence to follow-up. ConclusionThere is a gap between the awareness and practice of guidelines for the prevention and treatment of chronic hepatitis B （2022 edition） among clinicians. It is recommended to further strengthen training and focus on the whole process of “detection， diagnosis， treatment， and management” for patients with chronic hepatitis B in healthcare institutions， in order to promote the implementation of the guidelines.

OBJECTIVE: Left ventricular remodeling induced by myocardial ischemia/reperfusion injury (MI/RI) is a common cardiac dysfunction. Accumulating evidence has demonstrated that autophagy plays a vital role in protecting against ventricular remodeling. This study aims to investigate the performance of Compound Danshen Tablets (CDT) in rescuing ventricular remodeling and whether autophagy as the potential mechanism. METHODS: The left anterior descending arteries of rats were temporarily ligated for 30 min to construct the MI/RI model. Ventricular remodeling was induced by reperfusion for 28 d, during which the MI/RI rats were administered CDT (300 mg/kg and 600 mg/kg), atorvastatin (2 mg/kg), and diltiazem (16 mg/kg). Cardiac function and structure were examined by echocardiography. Immunohistochemistry, Masson's trichrome staining, and hematoxylin-eosin (HE) staining were utilized to assess the fibrosis and histological alterations in the heart tissue. The expression of autophagy-related proteins was detected using Western blotting. RESULTS: CDT attenuated the cardiac dysfunction, structural changes, histopathological changes and fibrosis induced by MI/RI. CDT significantly enhanced the level of Beclin1 and microtubule-associated protein 1 light chain 3 beta (LC3β), and reduced p62 levels in MI/RI rats. Moreover, CDT significantly increased the phosphorylation of adenosine monophosphate-activated protein kinase (AMPK) and inhibited mammalian target of rapamycin (mTOR) phosphorylation. CONCLUSION CDT ameliorated MI/RI-induced ventricular remodeling by activating autophagy and improving autophagic flux via the AMPK/mTOR signaling pathway.

Objective:To analyze the short-term clinical outcomes of total laparoscopic distal gastrectomy (TLDG) and laparoscopic-assisted distal gastrectomy (LADG) combined with Billroth-Ⅱ+Braun anastomosis.Methods:Clinical characteristics of patients undergoing laparoscopic distal gastrectomy combined with Billroth-Ⅱ+Braun anastomosis at Department of Gastrointestinal Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University from Jan 2020 to Oct 2022 were analyzed. Patients were divided into TLDG group ( n=62) and LADG group ( n=62) according to the surgical approach. Results:There were significant differences in the preoperative clinical data section between the two groups, and 124 patients (62 in each group) were enrolled after using propensity score matching to balance significant variables. Compared with the LADG group, the TLDG group showed statistically differences in time to first venting [(2.9±1.3) vs. (2.3±0.8) d, Z=-3.072, P=0.002], time to first fluid diet [(5.9±1.3) vs. (5.4±1.4) d, Z=-2.031, P=0.042] and incision length [(7.1±1.4) vs. (4.8±0.8) cm, Z=-6.331, P=0.000]. Total postoperative complication rate in the TLDG group and the LADG group (29% vs. 37%, χ2=0.911, P=0.340) was not statistically significant. Incidence of postoperative pneumonia was lower in the TLDG group than in the LADG group (3% vs. 13%, χ2=3.916, P=0.048), and incidence of all remaining postoperative complications were not statistically significant. There was no statistically significant difference in the incidence of serious postoperative complications between the TLDG and LADG groups ( P=1.000). Multifactorial analysis revealed that male ( P=0.023) and age ≥65 years ( P=0.001) were independent risk factors for postoperative complications. Conclusion:TLDG is safe and feasible and has better short-term clinical efficacy than LADG.

BACKGROUND:Osteoarthritis is one of the most common senile chronic degenerative diseases in China.Due to its complex pathogenesis and cellular molecular communication pathways,there is currently no effective method to slow down the progression of osteoarthritis.Studies have found that transforming growth factor-β is one of the key factors in the maintenance and regulation of joint stability and plays a significant role in the formation of early joints,as well as the development of bone and cartilage,and the remodeling of joints at various stages. OBJECTIVE:To review the regulatory role of the transforming growth factor-β subfamily in the occurrence and development of osteoarthritis,both domestically and internationally in recent years,to analyze the impacts it has at different stages of osteoarthritis,and to explore the potential application prospects of transforming growth factor-β in the clinical treatment of osteoarthritis,with a view to informing clinical treatment protocols.. METHODS:The relevant articles were searched by computer from CNKI Database and PubMed Database.The search terms were"osteoarthritis,transforming growth factor,signaling pathway,bone remodeling,cartilage degeneration,angiogenesis,treatment"in Chinese and English,respectively.Finally,57 articles were included for review. RESULTS AND CONCLUSION:The pathogenesis of osteoarthritis remains a subject of ongoing exploration with no unified consensus.Numerous studies highlight the close correlation between osteoarthritis and cytokines,focusing on the transforming growth factor-β superfamily as a pivotal mechanism and therapeutic breakthrough.Transforming growth factor-β plays a crucial role in early joint cartilage formation and maintenance,promoting cartilage repair.However,post-joint formation,its protective effect weakens,leading to potential destructive consequences.This dual regulatory role is a current clinical treatment focus,necessitating further research to delineate its application scope for standardized protocols.Highly active transforming growth factor-β participates in the regulation of bone cells,osteoblasts,and osteoclasts under mechanical stress,and intervenes in the subsequent remodeling of bone microstructure.Specific inhibitors present potential targeted therapeutics,yet their safety and efficacy in clinical settings require refinement.Vascular proliferation may serve as a potential disruptive pathway in transforming growth factor-β-mediated cartilage degeneration and subchondral bone remodeling.Abnormal communication pathways can further disrupt the homeostasis of the microenvironment of osteochondral units,thereby accelerating key pathological progressions of osteoarthritis.Research on transforming growth factor-β in osteoarthritic contexts is comprehensive,holding broad clinical application prospects.Drugs related to transforming growth factor-β are in clinical trial phases,but addressing potential impacts on other tissues and precise control of targeted delivery are critical concerns.As research advances,there is optimism for innovative breakthroughs in slowing the progression of osteoarthritis in the future.
