Gout in modern medicine is often attributed to "Li Jie Disease （历节病）"， "Bai Hu Wind" （白虎风）， and "Bi （痹） Syndrome" categories in traditional Chinese medicine， mainly because its joint pain often presents as wandering attacks， and the clinical symptoms are similar to those caused by wind. However， the essence of gout is actually dietary disorders caused by internal injuries， so it should not be classified as Bi （痹） syndrome due to wind， cold， dampness. Focusing on the theory of "gout is not Bi syndrome" proposed by TONG Xiaolin， combining ancient and modern medical literature and modern clinical research， this article analyzes the underlying etiology of gout， which originates from dietary irregularities and accumulation of turbid toxins， as well as the disease mechanism of "toxicity hurts joints and accumulation of toxins impairs the kidneys"， in order to clarify the essential difference between gout and impediment syndrome. Using the theory of "state-targeted diagnosis and treatment"， gout is classified into two categories： dampness-heat and deficiency-cold， and the treatment strategy of lowering the turbid toxin， facilitating the joints， and preserving the kidneys was proposed in order to guide the clinical practice.

Gastrointestinal (GI) cancers are a leading cause of cancer morbidity and mortality worldwide. Despite advances in treatment, cancer relapse remains a significant challenge, necessitating novel therapeutic strategies. In this study, we engineered nanobody-based chimeric antigen receptor (CAR) natural killer (NK) cells targeting cadherin 17 (CDH17) for the treatment of GI tumors. In addition, to enhance the efficacy of CAR-NK cells, we also incorporated CV1, a CD47-SIRPα axis inhibitor, to evaluate the anti-tumor effect of this combination. We found that CDH17-CAR-NK cells effectively eliminated GI cancers cells in a CDH17-dependent manner. CDH17-CAR-NK cells also exhibit potent in vivo anti-tumor effects in cancer cell-derived xenograft and patient-derived xenograft mouse models. Additionally, the anti-tumor activity of CDH17-CAR-NK cells is synergistically enhanced by CD47-signal regulatory protein α (SIRPα) axis inhibitor CV1, likely through augmented macrophages activation and an increase in M1-phenotype macrophages in the tumor microenvironment. Collectively, our findings suggest that CDH17-targeting CAR-NK cells are a promising strategy for GI cancers. The combination of CDH17-CAR-NK cells with CV1 emerges as a potential combinatorial approach to overcome the limitations of CAR-NK therapy. Further investigations are warranted to speed up the clinical translation of these findings.

AIM: To explore the clinicopathological and immunohistochemistry(IHC)characteristics of meibomian gland carcinoma(MGC).METHODS: Patients who were pathologically diagnosed as MGC from January 1, 2015 to December 31, 2020 in our hospital were enrolled, and their clinicopathological information was retrospectively analyzed. Cancer tissues from all the cases were IHC stained. En Vision two-step method, DAB staining, as well as hematoxylin re-staining were applied in the IHC assay.RESULTS: A total of 50 patients with 21 males and 29 females(1:1.38)were enrolled in the study, ranging from 26 to 80 years old, with a median age of 60 years. The upper eyelid, which was the predilection site, accounting for 66%(33/50). Histopathologically, moderately or poorly differentiated was in the majority(35/50, 70%). The expression rates of IHC parameters of MGC patients were as follows: GATA-3(49/50, 98%), EMA(49/50, 98%), CAM5.2(42/50, 84%), AR(41/50, 82%), MSH2(50/50, 100%), MSH6(50/50, 100%), MLH1(50/50, 100%), PMS2(50/50, 100%), Ki67(positive, 50%-90%). All the patients were followed up for 12 to 72 mo, with 5 cases of recurrence and 0 deaths.CONCLUSION: Pathological diagnosis of MGC should focus on observing cancer cells' cytoplasm to find relevant clues for cortical gland differentiation. Comprehensive analysis of multiple indicators is required when using IHC to assist diagnosis. For most MGC cancer cells, positive expressions of GATA-3, EMA, AR, CAM5.2 and a high Ki67 proliferation index could be always found. In addition, screening for Muir-Torre syndrome related IHC indicators could be also performed in diagnosing MGC simultaneously.

Objective To explore the effect of exposure to noise of 3.0T magnetic resonance imaging(MRI)on children's cochlear function.Methods We prospectively recruited 72 children who underwent cranial MRI examination at our hospital from May to November 2018;3M earplugs and sponge mats were used for hearing protection during MRI scanning.Noise level(dBA)of each MRI sequence was detected with a nonmagnetic microphone and a sound level meter.Distortion product otoacoustic emissions(DPOAE)test at 2-7 kHz was performed 24 hours before and 30 minutes after the MRI examination.Paired t-test or Wilcoxon signed-rank test was used to analyze differences in DPOAE amplitude before and after the MRI examination.Results The average noise level of MRI measured in the study was(107.7±3.92)dBA.Compared with that before the MRI examination,the DPOAE amplitude(dB)changed little after the MRI examination;the range of amplitude differences in each age group was as follows:left ear(-0.24-1.10)and right ear(-0.24-0.74)in the 0-1 year-old group;left ear(-0.07-0.59)and right ear(-0.57-0.75)in the 2-5 year-old group;left ear(-0.36-0.44)and right ear(-0.30-0.57)in the 6-12 year-old group.No statistically significant difference was found(correction P＞0.05).Conclusion No potential impact of 3.0T MRI noise on children's cochlear function was observed under routine hearing protection.

Objective:To investigate the current situation of medical equipment allocation in 103 tertiary public hospitals,analyze and compare the proportion of medical equipment in different regional hospitals in our country,and provide basis for scientific and reasonable allocation of medical equipment.Methods:A questionnaire was designed by literature research and expert consultation,and an electronic questionnaire was released through the public account of"China Medical Equipment"and the platform of"Good Medical Workers"to analyze the correlation between the number of medical equipment configuration,the proportion of domestic products,the region where the hospital was located and the number of hospital beds.Results:A total of 103 valid questionnaires were collected,involving 103 tertiary public hospitals in East China,North China,Central China,South China,Southwest,Northwest and Northeast China,of which 18%were in North China,37%were in East China and 9%were in South China.In North China,South China and East China,the average number of medical equipment in the tertiary public hospitals in the region was 9785 units per hospital,9245 units per hospital and 8153 units per hospital,and the number of the expensive equipment was relatively small,which had no correlation with the number of beds.There were statistically significant differences between North China and East China in the number of beds,the number of pieces of equipment per 100 beds and the amount of equipment per 100 beds(t=-2.582,2.939,4.653,P＜0.05).The number of life support equipment configuration was significantly positively correlated with the number of beds,and the domestic share,especially the domestic share of life support equipment,increased.Conclusion:The analysis of medical equipment allocation in public hospitals in China can provide data support for hospitals to better adapt to the adjustment of the new expensive medical equipment catalogue,provide reference for the demonstration and promotion of large medical equipment allocation and localization in tertiary hospitals,and provide reference for relevant health management departments.

【Objective】 To explore the model of "One Core, Multiple Elements" emergency blood donation volunteer team (referred to as the Model) . 【Methods】 The Nanjing City Voluntary Blood Donation Joint Meeting serves as the core, with diverse entities including party committees, government departments, district governments, social organizations, enterprises, blood donors, etc. Following the principles of "emergency response in emergencies, wartime readiness, combining regular and wartime efforts," and adhering to the framework of the Model, the emergency blood donation volunteer team system in Nanjing was constructed. 【Results】 1) After the construction of the Model (2018—2022), the total number of emergency blood donation volunteers in Nanjing City increased by 191% compared to the pre-construction period (2013—2017), with an average annual blood donation of 20 929, showing significant differences (P<0.05). 2) After the construction of the Model, the number of emergency blood donation during the winter and summer increased by 206% and 185%, respectively, compared to the pre-construction period, demonstrating significant differences (P< 0.05) .3) Prior to the construction of the Model, Nanjing lacked a relatively stable emergency volunteer team. After the construction, Nanjing established a total of 5 relatively stable volunteer teams, with the district-level government and township personnel accounting for the highest proportion (52.96%), followed by medical personnel (23.95%), enterprise team (11.10%), State-owned Assets Supervision and Administration Commission team (7%), and Nanjing municipal government team (4.98%). 4) Following the Model, during the COVID-19 pandemic, Nanjing successfully initiated two Level Ⅱ blood emergency responses, with emergency blood donations reaching 23 041. 【Conclusion】 The Model can effectively ensure the blood supply in Nanjing region during emergencies.

Inflammatory bowel disease （IBD）， mainly including ulcerative colitis （UC） and Crohn's disease （CD）， is a common chronic inflammatory disease of the gastrointestinal tract， with its incidence increasing year by year. Due to its long treatment duration， difficulty in treatment， prolonged remission， and high costs， it has attracted global attention. Exploring safe， effective， and sustainable treatment regimens has become an urgent global issue. The pathogenesis of IBD is complex， involving intestinal mucosal injury，disturbances in the internal environment， and inflammatory responses. In recent years， research has found that ferroptosis is also one of the important pathogenic factors of IBD. Ferroptosis， as a new form of non-apoptotic cell death， is characterized by iron dependence， lipid peroxidation， and imbalance in the redox system. Studies have shown that inhibiting ferroptosis in intestinal epithelial cells can protect the intestinal mucosa. Targeted intervention in ferroptosis may be a new direction for the treatment of IBD. IBD is mainly treated with drugs， including corticosteroids， aminosalicylates， biologics， and immunomodulators， but drug resistance and adverse reactions are common. Traditional Chinese medicine （TCM） has unique advantages such as low cost， low drug resistance， and fewer side effects， and has accumulated rich experience in the treatment of IBD. Scholars have confirmed that TCM can inhibit ferroptosis， and recent studies have shown that TCM can not only inhibit iron-dependent lipid peroxidation in intestinal cells but also enhance the antioxidant and anti-inflammatory abilities of intestinal mucosa， thus playing a role in the treatment of IBD. Increasing evidence suggests that TCM may treat IBD by interfering with ferroptosis. This article explores the relevance of TCM intervention in ferroptosis and the treatment of IBD， discusses the possible mechanisms of ferroptosis in IBD， and aims to provide a basis for the diagnosis and treatment of IBD.
