This study aims to review the current status and development trends of digital TCM (Traditional Chinese Medicine) specimen museums, providing a theoretical basis for their future construction. By systematically organizing literature and materials, practical experiences in platform architecture design, content planning, and technical implementation were summarized. The research results show that digital technology has significant application value in the TCM field. Currently, some Food and Drug Control Institutes have formed diverse construction achievements by integrating regional characteristics with technological innovation. However, current TCM specimen museums generally still face many challenges, such as insufficient digitalization. In conclusion, the digitalization of TCM specimen museums has become an inevitable trend in the industry. Targeted measures are urgently needed to solve existing problems and promote the sustainable development of digital TCM specimen museums. It is suggested to strengthen the standardization of data collection and storage, deepen the integration of technologies such as 3D, AR, and AI into the construction of specimen museums, and at the same time promote the spatial design combining regional culture with TCM. This will help create "one museum with one feature for one region" digital TCM specimen museums, further promoting their sustainable development and facilitating the digital inheritance of TCM.

BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

OBJECTIVE: To investigate the effectiveness of digital three-dimensional (3D) assisted unilateral biportal endoscopy (UBE) in the treatment of highly isolated lumbar disc herniation (LDH) with translaminar approach. METHODS: The clinical data of 59 patients who met the selection criteria and underwent UBE treatment due to highly isolated LDH between January 2022 and December 2023 were retrospectively analyzed. Among them, 25 cases were treated with digital 3D assisted translaminar approach (observation group) and 34 cases were treated with interlaminar approach (control group). There was no significant difference in gender, age, disease duration, surgical segment, and preoperative visual analogue scale (VAS) score and Oswestry disability index (ODI) between the two groups ( P>0.05). The operation time, intraoperative blood loss, and lateral articular surface preservation rate were recorded and compared between the two groups. VAS score and ODI were used to evaluate the improvements of pain and function before operation and at 3 and 6 months after operation. The modified MacNab criteria was used to evaluate the effectiveness at last follow-up. RESULTS: One patient in the control group had dural tear, and the other patients had no nerve injury, infection, dural tear, or other related complications. There was no significant difference in operation time and intraoperative blood loss between the two groups ( P>0.05). Patients in both groups were followed up 6-13 months, with an average of 8.3 months. The lateral articular surface preservation rate in the observation group was significantly higher than that in the control group ( P<0.05). Three patients in the observation group and 2 patients in the control group had calf muscle venous thrombosis, which was cured after anticoagulant treatment with rivaroxaban and delayed exercise time. There was no recurrence or second operation during the follow-up period. The VAS score and ODI of the two groups at 3 and 6 months after operation significantly improved when compared with those before operation ( P<0.05). There was no significant difference between the two groups at each time point after operation ( P>0.05). At last follow-up, the effectiveness was evaluated according to the modified MacNab criteria, and there was no significant difference in the evaluation grade and excellent and good rate between the two groups ( P>0.05). CONCLUTION UBE via translaminar approach is safe and effective for the treatment of highly isolated LDH, which is beneficial to protect the facet joint, maintain spinal stability, and reduce soft tissue injury. With the assistance of digital 3D technique, preoperative planning can be performed accurately.

Objective To obtain the protective performance parameters of barium sulfate mortar against positron nuclide γ-rays, provide reference data for precise shielding calculations, and guide the design, evaluation, and construction of radiation shielding. Methods The FLUKA program was used to build a model for simulating the dose equivalent rate variation around points of interest under the irradiation of the most commonly used positron nuclide ¹⁸F with changes in the thicknesses of lead and barium sulfate mortar. The transmission curves of lead and barium sulfate mortar were fitted, and the half-value layer (HVL) and lead equivalence of barium sulfate mortar were calculated based on the fitted curves. Results The ambient dose equivalent rate coefficient of positron nuclide ¹⁸F was 1.339 4×10⁻¹ μSv·m²/MBq·h and the HVL for lead was 4.037 mm, with deviations of 0.043% and 1.53% compared to the values provided in the AAPM Report No. 108, respectively. The HVLs for γ-rays produced by ¹⁸F, using barium sulfate mortar with apparent densities of 4.20, 4.00, and 3.90 g/cm³ mixed with 35.2-grade cement in a 4∶1 mass ratio, were 2.914, 2.969, and 3.079 cm, respectively. The lead equivalences were 0.1385, 0.1360, and 0.1311 mmPb/mm, respectively. Conclusion The three types of barium sulfate mortar can provide good protection against γ-rays in positron imaging locations. As the apparent density of barium sulfate increases, its protective effect improves slightly but remains significantly better than common construction materials like concrete and solid bricks.

Objective:To observe the clinical efficacy of unilateral biportal endoscopy (UBE) assisted bilateral decompression in the treatment of lumbar disc herniation with imaging herniation on one side and clinical symptoms on the contralateral side.Methods:A total of 20 patients with lumbar disc herniation with imaging herniation on one side and clinical symptoms on the contralateral side treated with UBE from January 2022 to January 2024 in the Affiliated Hospital of Binzhou Medical University were retrospectively analyzed. There were 9 males and 11 females, aged 50.4±14.0 years (range, 23-72 years). The intervertebral disc herniation level included L 3-4 in 1 case, L 4-5 in 15 cases, and L 5S 1 in 4 cases. There were 10 cases on the left side and 10 cases on the right side. The duration of symptoms was 24.1±33.7 months (range, 1-120 months). Visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate postoperative pain relief and functional recovery. The clinical efficacy was evaluated by modified MacNab criteria at 6 months after operation. Results:All patients successfully completed the operation. The operation time was 90.3±24.6 min (range, 55-134 mins). The VAS scores of patients at 3 days, 1 month, 3 months and 6 months after operation were 3.6±0.9, 2.2±0.7, 1.2±0.5 and 1.0±0.6, respectively, which were lower than those before operation (6.4±0.8), and the differences were statistically significant ( F=668.728, P<0.001). The ODI at 3 days, 1 month, 3 months and 6 months after operation were 34.2%±4.7%, 28.7%±2.8%, 24.3%±2.1% and 20.5%±2.0%, respectively, which were lower than 69.4%±5.2% before operation, and the differences were statistically significant ( F=515.578, P<0.001). The clinical efficacy was evaluated by modified MacNab criteria at 6 months after operation. Among 20 patients, 18 cases were excellent, 1 case was good, and 1 case was fair. All patients were followed up for 9.1±2.1 months (range, 6-14 months). One patient had a dural tear during the operation, but the range was small and there was no defect, and no further treatment was performed. Numbness of the lower limbs occurred 1 day after operation, and the symptoms disappeared after symptomatic treatment. There was no recurrence of lower limb symptoms, lumbar instability, intervertebral space infection or other complications at the last follow-up. Conclusion:Bilateral decompression with UBE is effective in the treatment of lumbar disc herniation with imaging herniation on one side and clinical symptoms on the contralateral side, which can improve the lumbar pain and function of patients.

Objective:To explore relevant factors to accurately diagnose BPPV in vertigo children. Methods:A retrospective study was conducted on the proportion of BPPV in children（<18 years） with vertigo who visited the Hearing and Vertigo Diagnosis and Treatment Center of Tianjin Medical University General Hospital from September 2017 to August 2023. The clinical characteristics of BPPV children, including general demographics, medical history, first visit department, comorbidities, canal involvement, response to treatment, and incidence of recurrence, were analyzed. Data analysis was conducted using SPSS 25.0 software. Results:BPPV was diagnosed in 22.8% of patients seen for vertigo during the study period. There are differences in the proportion of BPPV diagnosis among children with dizziness in different age groups（P<0.05）, and the diagnosis of BPPV in the 7-12-year-old group has a longer disease course than in the 13-17-year-old group（P<0.05）. 72.3%（47/65） of patients or their families were able to provide a typical history of positional vertigo. 49.2%（32/65） of BPPV patients had comorbidities, and there were differences in the proportion of comorbidities among different age groups of BPPV patients（P<0.05）. With the progress of study, the proportion of BPPV in children with vertigo has shown an upward trend, and the proportion of children with otolaryngology as the first diagnosis department has also increased（P<0.05）. The proportion of horizontal semicircular canals in children with BPPV has increased. All BPPV patients underwent canalith repositioning maneuvers, with good treatment outcomes and a recurrence rate of 12.3%（8/65）. The recurrence rate in the group of BPPV patients with comorbidities was 21.9%, which was higher than that in the group without comorbidities（P<0.05）. Conclusion:Childhood BPPV has clinical characteristics such as unclear medical history, high proportion of comorbidities, easy recurrence in BPPV children with comorbidities and high proportion of horizontal semicircular canal involvement. For children diagnosed with other vertigo diseases, do not ignore the BPPV diagnostic test. It is recommended to perform routine position tests on children with vertigo if conditions permit to reduce missed diagnosis of BPPV in children.

This study was aimed at investigating the immunoregulatory function of Mycobacterium tuberculosis Rv3641c gene in modulating host type Ⅰ interferon responses.The shuttle plasmid pMV261 was used to construct Rv3641c overexpression recombinant Mycobacterium smegmatis,and the biological characteristics of the recombinant bacteria were analyzed to explore the effect of Rv3641c on the growth curve,colony morphology and stress resistance of Mycobacterium.Subsequently,RAW264.7 cells were infected with Rv3641c overexpressing Mycobacterium smegmatis,and the transcriptional expression of genes related to the inhibition of type I inter-feron pathway was determined by RT-PCR.The expression level of IFN-βprotein was determined by ELISA,and the intracellular sur-vival level was determined.As a result,the recombinant rMS::pMV261-Rv3641c was successfully constructed.The results of biologi-cal characteristics analysis showed that Rv3641c did not affect the growth of mycobacteria,but significantly changed the colony mor-phology of mycobacteria and improved its resistance to H2O2.The results of recombinant bacteria infection experiments showed that Rv3641c significantly down-regulated the transcription levels of IFN-α,IFN-βand downstream ISGs genes CXCL10,IFIT2 and IL-1β in host cells,and Rv3641c significantly down-regulated the transcription levels of IFN-α,IFN-βand downstream ISGs genes CXCL10,IFIT2 and IL-1βin host cells.The results of intracellular colonization experiments showed that the intracellular mycobacte-ria in the overexpression recombinant bacteria infection group were significantly higher than those in the empty vector group,indicat-ing that Rv3641c could promote the intracellular surviv al of mycobacteria.In summary,the Rv3641c gene of M.tuberculosis can inhibit the host type I interferon response and promote the intracellular survival of M.tuberculosis,which provides a new idea for further explor-ing the immune escape function of M.tuberculosis and the discovery of new targets for anti-tuberculosis drugs.

Objective:To investigate the efficacy of oral folic acid intervention in lung cancer patients with radiation esophagitis (RE) caused by concurrent chemoradiotherapy.Methods:In this randomized, controlled, single-center clinical trial, a total of 82 patients with stage N 2-N 3 lung cancer including small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) admitted to the Affiliated Cancer Hospital of Guizhou Medical University from June 2022 to October 2023 were prospectively included. All enrolled patients were randomly divided into the experimental group (folic acid group) and control group according to 1 vs. 1 of simple random method, and patients in both groups were required to receive radiation therapy for lung lesions and mediastinal metastatic lymph nodes [≥2 cycles of chemotherapy were completed during the same period of radiotherapy (≥40 Gy / 20 F) or targeted drugs were given simultaneously]. The severity of RE was evaluated using the modified common terminology criteria for adverse events criteria of the National Cancer Institute in both groups weekly at the onset of radiation esophagitis symptoms and thereafter until 1 week after the end of radiotherapy. Conventional treatment of RE was delivered according to the grading criteria of the Radiation Therapy Oncology Group. Patients in the folic acid group were given with folic acid tablets 30 mg/d orally at the beginning of radiotherapy until the end of radiotherapy, while those in the control group did not receive any drug intervention. The onset time, severity and duration of RE, and changes in the severity of esophageal toxicity after conventional treatment were recorded and analyzed. Serum folate value, serum vitamin B 12 value and homocysteine value were measured before and after radiotherapy. For continuous quantitative variables, independent sample t-test or independent sample rank-sum test was used for comparison among different groups. For categorical data, Chi-square test or Fisher's exact probability method was used for comparison among different groups. Results:During the observation period, no grade 4 or above RE was reported between two groups. The incidence of grade 0, 1, 2 and 3 RE in the folic acid and control groups was 10% (4/40) and 5% (2/41), 70% (28/40) and 42% (17/41), 15% (6/40) and 51% (21/41), 5% (2/40) and 2% (1/41), respectively. The differences were not statistically significant between two groups ( P=0.456). However, the incidence of grade 0-1 RE in the folic acid group was significantly higher than that in the control group ( Z=2.72, P=0.006). The median time of RE in the folic acid group and control group was 12 d (range 7-52 d) and 15 d (range 11-56 d) after the start of radiotherapy, respectively, with no statistically significant difference ( χ2=-0.75, P=0.456). However, median duration of the individual's most severe RE was 12 d (range 4-36 d) and 21 d (range 7-38 d) in the folic acid group and control groups, respectively, and the differences were statistically significant ( χ2=2.10, P=0.039). In the folic acid group, the grades of swallowing with pain and dysphagia were significantly declined after folic acid intervention, especially at 2 weeks after the occurrence of RE ( P=0.001, P=0.002). The remission rate of RE after 1 week in the folic acid group was higher than that in the control group, and the difference was statistically significant ( χ2=7.36, P=0.012). Conclusion:Oral intake of folic acid during concurrent chemoradiotherapy for lung cancer cannot reduce the incidence of RE, but it may reduce its severity, shorten the duration of the most severe RE in individuals, and have a certain protective effect.
