As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

In hypoxic-ischemic brain damage (HIBD), the programmed cell death known as ferroptosis is significantly activated. Microglial cells demonstrate a high level of sensitivity to iron accumulation. Understanding how to regulate the dual role of microglia and transforming the microglial ferroptosis to a moderate and controllable process has considerable implications for the targeted treatment in HIBD. This paper serves as an overview of microglia-mediated ferroptosis in HIBD as a disease model. We discuss various aspects centered around microglia, including pathophysiological mechanisms, polarization and functions of microglia, molecular mechanisms of ferroptosis, signaling pathways, and therapeutic strategies. The review aims to provide a reference for studies of ferroptosis in microglia.

BACKGROUND: SMARCA2 (SWI/SNF Related, Matrix Associated, Actin Dependent Regulator of Chromatin, Subfamily A, Member 2) is an important ATPase catalytic subunit in the switch-sucrose nonfermenting (SWI/SNF) complex. However, its relationship with the pathological features of NSCLC and its prognosis remain unclear. METHODS: We retrospectively reviewed 2390 patients with surgically resected NSCLC, constructed tissue microarrays (TMAs) and performed immunohistochemical assays. We analyzed the correlation of SAMRCA2 with clinicopathological features and evaluated its prognostic value. RESULTS: Among 2390 NSCLC cases, the negative expression ratios of SAMRCA2, SMARCA4, ARID1A, ARID1B and INI1 were 9.3%, 1.8%, 1.2%, 0.4% and 0%, respectively. In NSCLC, male sex, T3 and T4 stage, moderate and poor differentiation, tumor ≥ 2 cm, Ki67 ≥ 15%, SOX-2 negative expression, middle lobe lesion and adenocarcinoma were relative risk factors affecting SMARCA2-negative expression. In lung adenocarcinomas, high-grade nuclei, histological morphology of acinar and papillary, solid and micropapillary and TTF-1-negative expression were relative risk factors affecting SMARCA2-negative expression. Kaplan-Meier survival analysis showed that the OS was shorter in the SMARCA2-negative group. Multivariate survival analysis revealed that SMARCA2-negative expression was an independent factor correlated with a poor prognosis in NSCLC. CONCLUSION In conclusion, SMARCA2-negative expression is an independent predictor of a poor outcome of NSCLC and is a potential target for NSCLC treatment.

Objective:To investigate the protective effect and mechanism of Icaritin Ⅱ (ICAⅡ) on bladder in radiation cystitis model.Methods:A total of 18 10-week-old male SD rats were selected from July 2021 to March 2022 and divided into control group, model group and treatment group by random number table method, with 6 cases in each group. Model group and treatment group were given a single dose of 20 Gy X-ray irradiation in the pelvic area. 24 h after irradiation, the treatment group was given ICAⅡ 4.5 mg/(kg·d) gavage, while the control group and model group were given the same volume of solvent (10% anhydrous ethanol, 20% isopropyl alcohol, 30% polyethylene glycol and 40% deionized water) gavage for 4 consecutive weeks. Drug eluting for 1 week. The bladder volume and leakage point pressure of the three groups of rats were measured by multi-conducting physiological apparatus, and the bladder function was evaluated. HE staining, Masson staining, ELISA, TUNEL staining and western blotting were performed on the bladder samples of the three groups of rats. The pathological changes (thickness of bladder mucosa, ratio of smooth muscle to collagen fiber), oxidative stress level (superoxide dismutase SOD, malondialdehyde), apoptosis rate, protein levels of inflammatory factors (IL-6, NF-kB) and anti-oxidative stress signaling pathway factors (Nrf2, HO-1) of the three groups of rats were compared.Results:After 4 weeks of modeling, in the model group, the bladder volume [(1.01±0.12)ml vs. (1.58±0.21)ml, P=0.001], the bladder leakage point pressure [(38.79±4.12) cmH 2O (1 cmH2O=0.098 kPa)vs.(60.59±3.81) cmH 2O, P=0.001], the ratio of smooth muscle of bladder wall to collagen fiber [1.78±0.17 vs.3.15±0.57, P=0.001], SOD[(6.31±0.73) U/mg vs.(14.67±1.04) U/mg, P=0.001] were lower than the control group, and the differences were statistically significant. In the model group, the thickness of bladder mucosa [(47.33±1.78)μm vs.(20.83±2.33)μm, =, P=0.001], malondialdehyde [(1.01±0.13) nmol/mg vs.(0.49±0.03) nmol/mg, P=0.001], IL-6 (0.87±0.11 vs. 0.33±0.10, P=0.001), NF-kB (0.71±0.14 vs. 0.29±0.07, P=0.001), apoptosis rate [(11.60±3.04)% vs. (3.91±1.40)%, P=0.007] was higher than the control group, and the differences were statistically significant. In the treatment group, the bladder volume [(1.27±0.13)ml, P=0.030], bladder leakage point pressure [(47.83±2.50)cmH 2O, P=0.004], smooth muscle to collagen fiber ratio (2.78±0.68, P=0.015), SOD[(10.48±0.85) U/mg, Compared with model group, bladder mucosa thickness [(31.94±3.20)μm, P=0.001], malondialdehyde [(0.64±0.09) nmol/mg, P=0.001], IL-6 (0.69±0.11, P=0.035), NF-kB (0.45±0.06, P=0.002) and apoptosis rate [(6.05±0.60)%, P=0.030] were lower than those in model group. The protein expression level of Nrf2 in model group (0.73±0.08 vs. 0.58±0.11, P=0.023) was higher than that in control group, but there was no significant difference in the protein expression level of downstream antioxidant factor HO-1 (0.50±0.14 vs. 0.35±0.06, P=0.060). Nrf2 protein expression level (0.88±0.03, P=0.027) and HO-1 expression level (0.68±0.07, P=0.026) in treatment group were higher than those in model group. Conclusion:ICAⅡ can reduce radiation cystitis injury, and its mechanism may be related to anti-oxidative stress and reducing inflammation.

Objective:To investigate the effect of six degree of freedom (6-DOF) bed combined with cone beam computed tomography (CBCT) in the on-line correction of setup errors in patients with primary rectal cancer.Methods:The clinicopathological data of 17 patients with primary rectal cancer in Department of Radiotherapy, Third Hospital of Peking University from July 2013 to January 2014 were collected. There were 14 males and 3 females, a median age of 65 years. The difference of CBCT and 6-DOF bed combined with CBCT online correction of patients with positioning error were retrospectively analyzed.Results:Before position correction, the first CBCT verification of setup errors in the three translation directions including X (left and right), Y (in and out) and Z (up and down) directions were (0.06±0.25) cm, (0.13±0.40) cm and (-0.28±0.31) cm, respectively. The setup errors of RX (rotation pitch), RY(rolling) and RZ (left and right rotation) directions were (0.62±1.15)°, (-0.19±0.99)°, and (-0.34 ± 0.84)°, respectively . After correction of IGRT combined with six freedom of bed, the setup errors of translation X, Y and Z were (0.01±0.09) cm, (-0.01±0.05) cm and (-0.03±0.08) cm, respectively, and the setup errors of rotation RX, RY and RZ directions were (-0.16±0.40)°, (0.36±0.31)°and (-0.01±0.25)°, respectively. There were significant differences in translation direction (X, Y and Z direction) and rotation direction (Rx, RY and RZ) before and after 6-DOF bed combined with CBCT correction (all P<0.05). In the translation direction, the higher frequency range of Z-direction error value was 0.20-0.79 cm. In the rotation direction, the frequency range of error in Rx direction was 0.20°-2.99°. There was no significant difference between bone mode and gray scale model registration ( P>0.05). With the progress of radiotherapy, the setup errors of X, Z, Rx, RY and RZ directions increased except Y direction. Conclusions:In radiotherapy, six freedom bed combined with CBCT is helpful to correct the setup errors of patients with primary rectal cancer. Six freedom bed may be used to correct the setup errors of patients with primary rectal cancer online. Image-guided radiation therapy (IGRT) is recommended for bone pattern registration in patients with rectal cancer.

Objective: To investigate the antimicrobial susceptibility of Brucella and to provide a scientific basis for rational drug use and effective treatment of patients with brucellosis. Methods: A total of 41 Brucella strains were isolated from the blood of patients with brucellosis in 5 counties and 2 districts in Yuxi City, China from 2014 to 2016. The susceptibility to 23 antimicrobial drugs was tested using Kirby-Bauer (K-B) disk diffusion method and the sizes of antimicrobial rings were recorded. The susceptibility testing results were interpreted according to the Drug Susceptibility Testing Guideline (2009 version) . Results: The susceptibility rate of Brucella was 100.00% to ofloxacin, ciprofloxacin, levofloxacin, and amikacin and >90% to cefotaxime, cefepime, imipenem, doxycycline, cefoperazone, minocycline, tobramycin, rifampicin, cefoperazone/sulbactam, and chloramphenicol. The high resistance to aztreonam and ampicillin was observed (87.80% and 41.46%). Doxycycline-intermediate strains, rifampicin-intermediate strains, and rifampicin-resistant strains were identified. Conclusion Doxycycline and rifampicin are commonly used in the treatment of brucellosis, but doxycycline/rifampicin-intermediate and-resistant strains have been identified. The susceptibility of Brucella to fluoroquinolones and cephalosporins was high, so the two drugs can be considered in the treatment of brucellosis.

OBJECTIVETo investigate the epidemic status of brucellosis in the occupational population in Yuxi, China, and to develop effective prevention and control strategies.

METHODSSerological test was performed for 2320 employees involved in breeding, slaughtering, meat and dairy product processing, veterinary medicine, and sales in counties and districts where brucellosis was detected from 2008 to 2014 in Yuxi; pathogenic detection was performed for those in the occupational population who were suspected of brucellosis.

RESULTSThe results of serological test showed that the infection rate of brucellosis reached 3.32% , and 15 cases of brucellosis had clinical symptoms. The employees involved in breeding had the highest infection rate (4.89%) (χ2=25.75, P<0.05). From 2008 to 2014, the infection rate of brucellosis was 0.37%~4.93% and tended to increase; 67.85% of the occupational population did not take personal protective measures and had a significantly higher infection rate than those who took personal protective measures (4.45% vs 0.94%; χ2=19.42, P<0.05). Among the 161 patients suspected of brucellosis, 42 cases were diagnosed as current brucellosis confirmed by laboratory pathogenic detection.

CONCLUSIONThe infection rate of brucellosis and the number of newly diagnosed cases tend to increase in the occupational population in Yuxi, and the employees involved in breeding are the major infected population.
