The promulgation of the Technical Specifications for Clinical Use of Blood (2025 Edition) signifies that China's clinical blood transfusion management has transitioned from mere technical operations to a new stage centered on patient blood management (PBM). Through an in-depth comparison of the new and old specifications, this paper analyzes the core transformations regarding conceptual reconstruction, legal alignment, technological upgrades, and closed-loop management. The new specifications establish PBM principles, reinforce legal safeguards for informed consent and emergency treatment, and construct a comprehensive, refined quality control system by specifying compatibility testing standards and introducing a post-transfusion evaluation system. Medical institutions should seize this opportunity to update management protocols and information systems, deepen multidisciplinary collaboration, and drive the profound transformation of clinical blood use from focusing solely on safety assurance to placing equal emphasis on science and value.

OBJECTIVE: To precise classify sacral meningeal cysts, effective guide minimally invasive neurosurgery and postoperative personalized rehabilitation by multiple dimensions radiographic reconstruction MRI. METHODS: From March to December 2021, based on the original 3D-fast imaging employing steadystate acquisition (FIESTA) scanning sequence, 92 patients with sacral meningeal cysts were pre-operatively evaluated by multiple dimensional reconstruction MRI. The shape of nerve root and the leakage of cyst were reconstructed according to the direction of nerve root or leakage track showed on original MRI scans. Sacral canal cysts were accurately classified as including nerve root and without nerve root, so as to accurately design the incision of skin and formulate corresponding open range of the posterior wall of the sacral canal. Under the microscope intraoperation, the shape of the nerve roots inside cysts or leakage track of the cysts without nerve roots were verified and explored. After the reinforcement and shaping operation, several reexaminations of multiple dimensional reconstruction MRI were performed to understand the deformation of the nerve root and hydrops in the operation cavity, so as to formulate a persona-lized rehabilitation plan for the patients. RESULTS: Among the 92 patients with sacral mengingeal cyst, 58 (63.0%) cysts with nerve root cyst, 29 (31.5%) cysts without nerve root cyst, and 5 (5.4%) cysts with mixed sacral canal cyst. In 58 patients with nerve root cysts, the accuracy of preoperative clinical classification on MRI image reached 96.6% (56/58) through confirmation by operating microscope. Only 2 cases of large single cyst with nerve root on the head of cyst were mistaken for without nerve root type. In 29 patients with sacral cyst without nerve root, the accuracy of preoperative image reached 100% through confirmation by operating microscope. The accuracy of judging the internal nerve root and leakage of 12 cases with recurrent sacral cyst was also 100%. Two cases of delayed postoperative hydrops were found one month after operation. After rehabilitation treatment by moxibustion and bathing, the hydrops disappeared 4-6 months after operation. CONCLUSION Multiple dimensional reconstruction MRI can precisely make clinical classification of sacral meningeal cysts before operation, guide minimally invasive neurosurgery effectively, and improve the rehabilitation effect.

Purpose: This Phase II trial was objected to evaluate the efficacy and safety of adding fulvestrant to neoadjuvant chemotherapy in patients with estrogen receptor (ER)+/human epidermal growth factor receptor 2 (HER2)– locally advanced breast cancer (LABC). Additionally, the study aimed to investigate the association of 16α-18F-fluoro-17β-fluoroestradiol (18F-FES) positron emission tomography (PET)–computed tomography (CT) and metabolites with efficacy. Materials and Methods: Fulvestrant and EC-T regimen were given to ER+/HER2– LABC patients before surgery. At baseline, patients received 18F-FES PET-CT scan, and plasma samples were taken for liquid chromatography–mass spectrometry analysis. The primary endpoint was objective response rate (ORR). Secondary endpoints included total pathologic complete response (tpCR) and safety. Results: Among the 36 patients enrolled, the ORR was 86.1%, the tpCR rate was 8.3%. The incidence of grade ≥ 3 treatment-emergent adverse events was 22%. The decrease in ER value in sensitive patients was larger than that in non-sensitive patients, as was Ki-67 (p < 0.05). The maximum standardized uptake value, mean standardized uptake values, total lesion ER expression of 18F-FES PET-CT in sensitive patients were significantly higher than those in non-sensitive patients (p < 0.05). Moreover, these parameters were significantly correlated with Miller and Payne grade and the change in ER expression before and after treatment (p < 0.05). Thirteen differential expressed metabolites were identified, which were markedly enriched in 19 metabolic pathways. Conclusion This regimen demonstrated acceptable toxicity and encouraging antitumor efficacy. 18F-FES PET-CT might serve as a tool to predict the effectiveness of this therapy. Altered metabolites or metabolic pathways might be associated with treatment response.

Objective:To compare the clinical efficacy of endoscopic posterior transforaminal lumbar interbody fusion (Endo-PTLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in the treatment of single-segment lumbar degenerative diseases.Methods:A retrospective analysis was conducted on the clinical data of 56 patients with single-segment lumbar degenerative diseases treated at Xiuzhou District People's Hospital between September 2020 and March 2023. Patients were divided into two groups based on the surgical approach: the Endo-PTLIF group (24 cases, 11 males and 13 females; mean age: 56.5±8.4 years, range: 43-72 years) and the MIS-TLIF group (32 cases, 10 males and 22 females; mean age: 54.5±10.4 years, range: 37-73 years). Perioperative parameters, visual analog scale (VAS) scores for pain, Oswestry disability index (ODI), lumbar lordosis (LL), disc height (DH), and dural sac cross-sectional area (DSCA) were compared between the two groups.Results:No significant differences were observed between the two groups in baseline characteristics, preoperative VAS, ODI, LL, DH, or DSCA ( P>0.05). However, the operative time in the Endo-PTLIF group (173.9±12.3 minutes) was significantly longer than in the MIS-TLIF group (136.5±19.5 minutes, P<0.05). Similarly, the Endo-PTLIF group required more fluoroscopy exposures (15.9±1.8) than the MIS-TLIF group (13.0±1.6, P<0.05). In contrast, intraoperative blood loss in the Endo-PTLIF group (68.9± 12.9 ml) was significantly lower than in the MIS-TLIF group (126.7±35.4 ml, P<0.05). Additionally, the Endo-PTLIF group had a shorter hospital stay [7.00 (6.25, 7.75) days] compared to the MIS-TLIF group [10.00 (9.25, 11.00) days, P<0.05]. At one week and one month postoperatively, the Endo-PTLIF group had significantly lower back pain VAS scores [2.00 (2.00, 3.00) and 2.00 (2.00, 2.00), respectively] and a lower ODI (25.83%±3.83%) compared to the MIS-TLIF group [3.00 (2.25, 4.00), 2.50 (2.00, 3.00), and 30.09%±4.02%, respectively; P<0.05]. Beyond one month postoperatively, there were no significant differences in leg pain VAS scores between the groups, and back pain VAS and ODI showed no significant differences after six months ( P>0.05). At the final follow-up, the excellent and good rates, according to MacNab criteria, were 95.8% in the Endo-PTLIF group and 93.8% in the MIS-TLIF group, with no significant difference ( P>0.05). At 12 months postoperatively, both groups showed significant improvements in LL, DH, and DSCA compared to preoperative values ( P<0.05), but there were no significant differences between the two groups ( P>0.05). The fusion rates were 96% in the Endo-PTLIF group and 94% in the MIS-TLIF group, with no significant difference ( P>0.05). Complications included one case of dural tear in the Endo-PTLIF group, and one case of dural tear and one case of incision infection in the MIS-TLIF group. Conclusion:Endo-PTLIF achieves comparable clinical efficacy to MIS-TLIF in the treatment of single-segment lumbar degenerative diseases, with the added advantages of reduced intraoperative blood loss and faster postoperative recovery.

Objective:To investigate the number of medical institutions and staff involved in 131I diagnosis and therapy in China, and to ascertain the level of 131I activity incorporated in thyroid of medical staff performing the 131I treatment. Methods:Questionnaires were used to investigate the basic information on nuclear medicine practices in all the non-military hospitals in China. Portable gamma spectrometers were used to determine and analyze the 131I activity in thyroid of the medical staff in some radioiodine treatment workplaces. The result were reported through National Radiological Health Information Platform. Results:Until December 2022, there had been 959 hospitals performing clinical nuclear medicine practices in China, with a total of 10 820 medical staff. In China, there have been 623 hospitals performing 131I therapeutical procedures, accounting for 65.0% of all nuclear medicine hospitals, and 333 hospitals performing 131I treatment of thyroid cancer, accounting for 34.7%. The hospitals equipped with automated radiopharmaceutical dispenser accounted for 61.3% of the 623 hospitals. A total of 2 210 nuclear medicine staff were monitored for internal exposure in 20 provinces in 2022, with 249 (11.3%) having activities above 100 Bq and the maximum value of 2.9 × 10 4 Bq. A total of 426 nuclear medicine staff in four provinces were detected using HPGe detectors, with 101 (23.7%) detected to have 131I in their thyroid glands. A total of 1 748 in 17 provinces were detected using NaI or LaBr detectors, with 379 (21.2%) detected to have 131I in their thyroid glands. The detection rate of 131I in the staff was found to increase with the increased amount of 131I purchased by hospitals. The detection rate of 131I in the hosptitals having purchased the amount of 131I≥3.70 × 10 6 MBq in 2021 was 32.1%. This value was notably higher than in the other three groups whose purchased amount <3.70 × 10 6 MBq, with a statistically significant difference( χ2=15.46, P < 0.001). Conclusions:There were great differences in the number of both hospitals and staff performing 131I treatment between different provinces in China. About one fifth of the staff in the 131I treatment workplaces could be detected to have incorporated 131I in their thyroid glands.

Objective To explore the diagnostic value of serum C-C motif chemokine ligand 3(CCL3)and Semaphorin 3A in patients with type 2 diabetes mellitus(T2DM)complicated by osteoporosis(OP).Methods A total of 125 patients with T2DM complicated by OP who visited the hospital from August 2022 to August 2023 were selected as the OP group,and another 125 patients with T2DM without OP who visited the hospital during the same period were selected as the T2DM group.The OP group was divided into Group A(T value>-1.0,but slightly lower than the normal value),Group B(T value between-2.5 and-1.0),and Group C(T value<-2.5)based on the measurement results of bone mineral density(BMD).The lev-els of serum CCL3 and Semaphorin 3A in each group were compared.Pearson correlation analysis was used to analyze the correlations between serum CCL3,Semaphorin 3A and BMD in patients with T2DM complicated by OP.Multivariate Logistic regression analysis was used to analyze the influencing factors of T2DM compli-cated by OP.The receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of se-rum CCL3 and Semaphorin 3A for T2DM complicated by OP.Results Compared with the T2DM group,the serum CCL3 level in the OP group increased,and the Semaphorin 3A level decreased,and the difference was statistically significant(P<0.05).Compared with group A,the serum CCL3 levels in group B and group C increased,while the Semaphorin 3A level decreased,and the differences were statistically significant(P<0.05).Compared with group B,the serum CCL3 level in group C increased and the Semaphorin 3A level de-creased,and the difference was statistically significant(P<0.05).Compared with the T2DM group,the femo-ral neck bone BMD,lumbar spine BMD and total hip BMD in the OP group were significantly decreased,and the difference was statistically significant(P<0.05).The serum CCL3 level in patients with T2DM accompa-nied by OP was negatively correlated with femoral neck bone BMD,lumbar spine BMD and total hip BMD(P<0.05),and the serum Semaphorin 3A level was positively correlated with femoral neck bone BMD,lum-bar spine BMD and total hip BMD(P<0.05).The results of multivariate Logistic regression analysis showed that CCL3 was an independent risk factor for T2DM with OP(P<0.05),and Semaphorin 3A was an inde-pendent protective factor for T2DM with OP(P<0.05).The results of ROC curve analysis showed that the area under the curve(AUC)of serum CCL3,Semaphorin 3A and their combination diagnosis of T2DM accom-panied by OP were 0.810,0.802 and 0.869,respectively.The AUC of the combined diagnosis of T2DM ac-companied by OP was superior to their individual diagnoses(Zcombination-CCL3=2.235,Zcombination-Semaphorin 3A=2.021,P=0.025,0.043).Conclusion The serum CCL3 level is increased in patients with T2DM accompanied by OP,and the Semaphorin 3A level is decreased.The combination of the two has certain diagnostic value for T2DM accompanied by OP.

Objective To analyze the development of nuclear medicine services in Hunan Province and to assess internal radiation doses among the nuclear medicine workers (NMWs) involved in iodine-131 radionuclide therapy. Methods Based on a survey of nuclear medicine institutions in Hunan Province, a total of 61 NMWs from seven hospitals providing iodine-131 therapy for thyroid cancer were selected as the study subjects by convenience sampling method. Thyroidal iodine-131 activity was measured using a portable gamma spectrometer to estimate internal dose and total annual effective dose. Results A total of 47 nuclear medicine institutions were reported in Hunan Province by 2023, most of which were public and tertiary hospitals, accounting for 38. Iodine-131 therapy was performed in 30 institutions, including nine for thyroid cancer. A total of nine participants had detectable thyroidal iodine-131 activity among 61 workers involved in iodine-131 thyroid cancer treatment, with the detection rate of 14.8%. Their internal radiation annual committed effective doses ranged from 0.100 to 1.584 mSv, with a mean of 0.499 mSv and median of 0.426 mSv. Except for one cleaner, the remaining eight physicians and nurses had the total annual effective doses ranging from 0.311 to 3.007 mSv, with a mean of 1.305 mSv, all below the annual dose limit of 20.000 mSv among radiation workers specified in national standard. Conclusion Internal exposure to iodine-131 among the NMWs should not be neglected. Standardized procedures and strengthened internal dose monitoring are recommended.

Purpose: This Phase II trial was objected to evaluate the efficacy and safety of adding fulvestrant to neoadjuvant chemotherapy in patients with estrogen receptor (ER)+/human epidermal growth factor receptor 2 (HER2)– locally advanced breast cancer (LABC). Additionally, the study aimed to investigate the association of 16α-18F-fluoro-17β-fluoroestradiol (18F-FES) positron emission tomography (PET)–computed tomography (CT) and metabolites with efficacy. Materials and Methods: Fulvestrant and EC-T regimen were given to ER+/HER2– LABC patients before surgery. At baseline, patients received 18F-FES PET-CT scan, and plasma samples were taken for liquid chromatography–mass spectrometry analysis. The primary endpoint was objective response rate (ORR). Secondary endpoints included total pathologic complete response (tpCR) and safety. Results: Among the 36 patients enrolled, the ORR was 86.1%, the tpCR rate was 8.3%. The incidence of grade ≥ 3 treatment-emergent adverse events was 22%. The decrease in ER value in sensitive patients was larger than that in non-sensitive patients, as was Ki-67 (p < 0.05). The maximum standardized uptake value, mean standardized uptake values, total lesion ER expression of 18F-FES PET-CT in sensitive patients were significantly higher than those in non-sensitive patients (p < 0.05). Moreover, these parameters were significantly correlated with Miller and Payne grade and the change in ER expression before and after treatment (p < 0.05). Thirteen differential expressed metabolites were identified, which were markedly enriched in 19 metabolic pathways. Conclusion This regimen demonstrated acceptable toxicity and encouraging antitumor efficacy. 18F-FES PET-CT might serve as a tool to predict the effectiveness of this therapy. Altered metabolites or metabolic pathways might be associated with treatment response.
