Objective:To evaluate the safety and efficacy of accelerator-based boron neutron capture therapy (AB-BNCT) in the treatment of recurrent and refractory malignant tumors.Methods:The data of 14 patients admitted to Xiamen Humanity Hospital from September 2022 to April 2023 were prospectively collected, including 7 patients with primary brain malignancies and 7 patients with locally recurrent inoperable head and neck malignancies. All patients received intravenous infusion of boron drug (NBB-001, p-dihydroxyborylphe nylalanine, a patented freeze-dried formulation) at a total nominal dosage of 500 mg/kg (11 patients) or 750 mg/kg (3 patients), and were irradiated with neutrons (operating with NeuPex system). Adverse events after treatment were recorded and assessed. The primary efficacy endpoint was the 90 d objective response rate (ORR), while the secondary endpoints included progression-free survival (PFS) and complete response rate (CRR). Data were compiled and analyzed by SAS 9.4 software. The rate and 95% CI were calculated using Clopper-Pearson method. Results:The median dose delivered to 80% of the target volume (D 80%) was 16.80 GyE (range: 8.93-23.79 GyE). The most common adverse reactions were hyperamylasemia, alopecia, and hyperprolactinemia. Five patients experienced 8 cases of grade 3 or above adverse events, including 1 case of grade 4 acute kidney injury and 7 cases of grade 3 adverse events. All adverse events were recovered after observation or treatment. At 90 d after treatment, the ORR of all patients was 9/14 (64%, 95% CI: 35%-87%), disease control rate (DCR) was 10/14 (71%, 95% CI: 42%-92%), CRR was 2/14 (14%, 95% CI: 2%-42%); and the best overall response during the entire course included an ORR of 10/14 (71% ,95% CI: 42%-92%), DCR of 13/14 (93%, 95% CI: 66%-100%), and CRR of 3/14 (21% ,95% CI: 5%-51%). The 1-year survival rate for head and neck malignancies was 71.4%, and the 2-year survival rate was 42.8%. The 1-year survival rate for recurrent brain malignancies was 42.8%. Conclusion:AB-BNCT demonstrates favorable safety and promising efficacy in treating primary brain malignancies and recurrent/refractory head and neck malignancies, representing a potential therapeutic option.

OBJECTIVE:
To analyze the important effect of 3D printing personalized lumbar support on lumbar pain and lumbar function in patients with lumbar disc herniation.
METHODS:
From October 2018 to May 2021, 60 patients initially diagnosed with lumbar disc herniation were selected and divided into an observation group and a control group, with 30 patients in each group. Among them, there were 18 males and 12 females in the observation group;the age ranged from 24 to 56 years old, with an average of (45.23±6.07) years old. The course of disease ranged from 1 to 24 months, with an average of(6.25±0.82) months, and rehabilitation treatment was carried out by wearing 3D printed personalized lumbar support. There were 19 males and 11 females in the control group;the age ranged from 25 to 57 years old, with an average of (42.78±7.58) years old. The course of disease ranged from 1 to 24 months, with an average of (6.72±1.36) months, and rehabilitation treatment is carried out by wearing traditional lumbar protective equipment. The Japanese Orthopaedic Association (JOA) scores, lumbar Oswestry dysfunction index (ODI) and visual analogue scale (VAS) were evaluated and compared between the two groups before and 1 course after treatment (3 weeks).
RESULTS:
There was no statistically significant difference in JOA, ODI, and VAS between two groups before treatment (P>0.05). After one course of treatment (3 weeks), JOA scores of both groups was increased compared to before treatment (P<0.05), while ODI and VAS decreased compared to before treatment (P<0.05). After treatment, JOA score of observation group was higher than that of control group (P<0.05), while ODI and VAS scores were lower than those of control group. No adverse events occurred in both groups.
CONCLUSION
The application of 3D printing personalized lumbar support can effectively alleviate the pain of patients with lumbar disc herniation and improve their lumbar function of patients.

ObjectiveTo investigate the value of percutaneous and intravenous contrast-enhanced ultrasound(P-Ⅳ-CEUS) in sentinel lymph nodes(SLNs) after resection of early-stage primary breast cancer. MethodsA retrospective analysis was done on the clinical and imaging data of 42 early breast cancer patients. Following primary tumor resection, all these patients underwent reoperation in our hospital. SLNs were examined by preoperative P-Ⅳ-CEUS and intraoperative sentinel lymph node biopsy(SLNB) was performed by using Methylene blue as a tracer. Then we analyzed the detection and false-negative rate in CEUS and SLNB respectively. By using the surgical pathological results as the gold standard, the diagnostic efficacy of CEUS for SLNs was explored. ResultsThe detection rate and false negative rate of SLNs in percutaneous contrast-enhanced ultrasound (P-CEUS) were 92.9% (39/42) and 7.1% (3/42), respectively. The detection rate in methylene blue staining was 100% (41/41) and one patient underwent neoadjuvant therapy due to biopsy-confirmed metastasis. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of P-Ⅳ-CEUS were 66.7% (2/3), 100% (37/37), 100% (2/2), 97.3% (36/37) and 97.4% (38/39), respectively. ConclusionsP-Ⅳ-CEUS after resection of early-stage primary breast cancer can accurately detect SLNs and characterize their status, which is a reliable clinical basis for reducing invasive SLNB.

In this paper, the name, classification, origin and other aspects of Schizonepetae Herba in the famous classical formulas were researched by referring to the related herbal literature, medical books and prescription books in the past dynasties. The results showed that Schizonepetae Herba first appeared in Shennong Bencaojing (《神农本草经》) as Jiasu, while Jingjie first appeared in Wupu Bencao (《吴普本草》), and the name of Jingjie was mainly used as the rectification of name in later generations. The name of Jiasu is mostly derived from its smell, and the name of Jingjie is mostly derived from its pronunciation. Schizonepeta tenuifolia has been highly praised in the past as a original material, and its genuine producing area is Jiangsu, Hebei and other places, medicinal part is whole herb with spike. In modern times, the quality of Schizonepetae Herba is best described as having thin stems, green spike, and aroma. In clinical application, the raw products of Schizonepetae Herba is mainly used, and the carbonisata is mainly used for hemostasis. Famous classical formulas of Huaihuasan and Danggui Yinzi are all made of Schizonepetae Spica, so it is recommended to use the dried panicle of S. tenuifolia. In Liangxue Dihuangtang, Schizonepetae Herba Carbonisata is used, therefore, it is suggested to adopt the processing method of Schizonepetae Herba Carbonisata in the 2020 edition of Chinese Pharmacopoeia.
