Hospital culture refers to the unique values and hospital spirit forged in the long-term provision of medical services,which exerts a significant impact on a hospital's comprehensive competitiveness and soft power.Party building plays a crucial role in the construction and development of hospital culture.The hospital's people-oriented cultural philosophy is inher-ently consistent with the Party's fundamental purpose of serving the people wholeheartedly;therefore,Party building is of great significance for shaping hospital culture—as the inherent soul and driving force of a hospital—and promoting the sound develop-ment of the hospital.This paper analyzes the problems existing in the guidance of cultural construction by Party building in the 5th Party Branch of the Geriatrics & Gerontology Research Institute of Guangdong Provincial People's Hospital,such as misalign-ments in ideological understanding,a shortage of Party affairs cadres,and inadequate excavation of cultural connotations.Draw-ing on the branch's experience and achievements,this paper introduces the specific measures and experiences of Party building guiding hospital cultural construction,including delving deeply into spiritual culture,intensifying efforts in institutional culture,fostering a culture of integrity,expanding service-oriented culture,and nurturing a culture of role models and heroes.Further-more,it puts forward valuable experiences:taking institutional development as the foundation to solidify the core mechanism of political guidance;taking innovative practices as the means to construct a multi-dimensional integrated promotion system;and a-dopting a problem-oriented approach as the pathway to drive the transformation and upgrading of practical outcomes.

Objective To discuss the value of diffusion-weighted MRI (DWI) and 18F-FDG-PET/CT in assessing the early therapeutic effect of radiofrequency ablation (RFA) for VX2 sarcomas in experimental rabbits. Methods VX2 sarcoma was inoculated at bilateral hind limbs in 14 New Zealand white rabbits to establish the animal models. The implanted VX2 tumor on one hind leg was treated with ultrasound-guided percutaneous RFA (study group), while no RFA was given to the VX2 tumor on the contralateral hind leg (control group). DWI-MRI was performed at 2 days after RFA, and 18F-FDG-PET/CT examination was employed at 3 days after RFA. The mean apparent diffusion coefficient (ADC) values and standard uptake value (SUV) of the untreated tumor and the ablated tumor were separately calculated. Taking the pathologic result as the gold standard, the consistency of DWI-MRI, PET/CT as well as the combination of DWI-MRI and PET/CT with the clinical diagnosis was separately evaluated by Kappa test. Results Before RFA, DWI-MRI demonstrated that the VX2 tumor was characterized by hypo-intensity signal on T1 and hyper-intensity signal on T2 with ring-shaped enhancement on T1-weighted image; PET/CT showed that the tumor had nodular or ring-shaped 18F-FDG accumulation. After RFA, DWI-MRI revealed that the VX2 tumor was manifested as hyper-intensity signal on T1 and slight higher density on T1 with slight enhancement on contrast-enhanced T1-weighted image; PET/CT showed lowered accumulation of 18F-FDG. The mean ADC value of the ablated tumor was (1.52 ± 0.24) × 10-3 mm2/s, which was obviously higher than that of the un-ablated tumor, that was (1.09 ± 0.12) × 10-3 mm2/s, the difference was statistically significant(P<0.05). The mean SUV value of the ablated tumor was (0.6 ± 0.3), which was significantly lower than that of the ablated tumor (9.6 ± 3.2, P<0.05). No significant difference in sensitivity, specificity and accuracy existed between DWI-MRI and pathology as well as between PET/CT and pathology, the Kappa value being 0.357 and 0.428 respectively (P>0.05). The Kappa value of the consistency between combination of DWI-MRI with PET/CT and pathology was 0.786, which was significantly different from the result by simple DWI-MRI or simple PET/CT evaluation (P< 0.05). Conclusion Both ADC value of DWI-MRI and SUV value of PET/CT are useful indexes for evaluating the early therapeutic effect of RFA. Both DWI-MRI and PET/CT have their respective advantages, nevertheless, combination use of both can effectively improve the evaluation of curative effect for VX2 tumor after RFA in experimental rabbits.
