Ferroptosis is a novel form of programmed cell death that plays a critical role in the body's disease resistance processes. Research has shown that ferroptosis plays a significant role in the pathogenesis of depression. Traditional Chinese medicine （TCM） has unique advantages in the prevention and treatment of depression， and the effective application of ferroptosis theory to guide TCM in the prevention and treatment of depression has become a current research hotspot. This article provides a summary and review of the regulatory mechanisms of ferroptosis， its relationship with depression， and the current research status of TCM in the prevention and treatment of depression based on ferroptosis. It has been found that the occurrence of ferroptosis is related to processes such as iron metabolism disorders， uncontrolled lipid peroxidation， and abnormal amino acid metabolism. Ferroptosis plays an important regulatory role in the onset， progression， and treatment of depression， offering new ideas for therapeutic approaches to the condition. Additionally， research on TCM interventions that regulate ferroptosis to exert antidepressant effects has identified several effective components， such as saikosaponin B₂， luteolin， quercetin， gallic acid， catalpol， turmerone， oxypaeoniflorin， and traditional compound formulas such as Dihuang Yinzi and Xiaoyaosan， as well as acupuncture and moxibustion. These interventions have been shown to exert antidepressant effects by regulating ferroptosis， providing scientific evidence and references for further research into ferroptosis theory and its application in guiding the prevention and treatment of depression through TCM.

Objective To verify the accuracy of γ spectrometry by analyzing the results of national interlaboratory comparisons of radionuclide analysis by γ spectrometry from 2018 to 2023. Methods A statistical analysis was conducted on the results from multiple years of participation in the national interlaboratory comparisons of radionuclide analysis by γ spectrometry. The measurement results of radionuclide specific activities in soil were analyzed to provide technical support for improving the capability to analyze radionuclides in soil. Results The laboratory participated in six interlaboratory comparisons and conducted 23 radionuclide analyses by γ spectrometry from 2018 to 2023. The relative deviation was −12.20% to 8.11%, the |Z_test| was 0 to 0.61, the U_test was 0 to 0.62, and the U_rel was 0.07 to 0.12. The overall pass rate was 100% and the excellent rate was 33.3%. In addition, 21 of the 23 (91.3%) radionuclide analyses showed full scores in experiment operation. However, the total scores were relatively low due to multiple oversights and lack of rigor in the preparation of the test reports, which prevented the laboratory from qualifying for the excellence evaluation process, resulting in a relatively low excellent rate. Conclusion The interlaboratory comparisons indicate that the measurements of radionuclides in this laboratory were all qualified, with full scores for experiment operation in several analyses. These results demonstrate that the soil radionuclide analysis system based on γ spectrometry is reliable and stable.

ObjectiveTo investigate the pathogenic spectrum and epidemiological characteristics of diarrheal disease in Fengxian District of Shanghai, and to provide scientific basis for the prevention and control of diarrheal diseases. MethodsBasic information of the initial adult cases visited diarrheal disease surveillance sentinel hospital in Fengxian District, Shanghai, was collected from August 2013 to 2023, and fecal samples were collected at 1∶5 sampling intervals to isolate and identify 5 kinds of diarrheagenic Escherichia coli (DEC), Salmonella (SAL), Vibrio parahaemolyticus, Campylobacter, Vibrio cholerae, Shigella and Yersinia enterocolitica (YE). Simultaneously, nucleic acid detection was performed for 3 kinds of rotavirus, 2 kinds of norovirus, intestinal adenovirus, astrovirus and sapovirus. ResultsA total of 1 861 cases of newly diagnosed diarrheal disease were reported, with the peak in July to August. Additionally, 704 surveillance samples were detected, with a total positive detection rate of 50.57%. The detection rates of bacterial, viral and mixed infection were 25.14%, 21.02% and 4.40%, respectively. Among the pathogens detected, DEC accounted for the highest (17.61%, 124/704), followed by norovirus (16.48%, 116/704), rotavirus (6.39%, 45/704), SAL (5.97%, 42/704) and Campylobacter (3.84%, 27/704). DEC detected were mainly enteroaggregative Escherichia coli and enterotoxigenic Escherichia coli, with no detection of Vibrio cholerae, Shigella and YE. The highest total pathogen detection rate was observed from June to September, and the detection peaks of norovirus were from March to June and from October to December, whereas that of DEC was from June to October. The detection rate of rotavirus peaked from January to February, but which was not detected between 2020‒2023. The SAL positive rate peak was in September, whereas that of Campylobacter was from July to September. ConclusionThe main pathogens detected in Fengxian District from 2013‒2019 are DEC, norovirus, rotavirus, SAL and Campylobacter. Different pathogens have different detection peaks, with bacteria predominating in summer and viruses in winter and spring. Prevention and control measures should be carried out according to the epidemiological characteristics of different seasons.

Cervical spine health issues not only seriously affect patients' quality of life but also impose a heavy burden on the social healthcare system. Existing guidelines lack sufficient clinical guidance on lifestyle and work habits, such as exercise, posture, daily routine, and diet, making it difficult to meet practical needs. To address this, relying on the China Association of Chinese Medicine, Wangjing Hospital of China Academy of Chinese Medical Sciences took the lead and joined hands with more than ten institutions to form a multidisciplinary guideline development group. For the first time, the group developed the Guidelines for Cervical Spine Health Intervention based on evidence-based medicine methods, strictly following the standardized procedures outlined in the World Health Organization Handbook for Guideline Development and the Guiding Principles for the Formulation/Revision of Clinical Practice Guidelines in China (2022 Edition). This proposal systematically explains the methods and steps for developing the guideline, aiming to make the guideline development process scientific, standardized, and transparent.

BACKGROUND: Preclinical studies have indicated that Angong Niuhuang Pills (ANP) reduce cerebral infarct and edema volumes. This study aimed to investigate whether ANP safely reduces cerebral infarct and edema volumes in patients with moderate to severe acute ischemic stroke. METHODS: This randomized, double-blind, placebo-controlled pilot trial included patients with acute ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores ranging from 10 to 20 in 17 centers in China between April 2021 and July 2022. Patients were allocated within 36 h after onset via block randomization to receive ANP or placebo (3 g/day for 5 days). The primary outcomes were changes in cerebral infarct and edema volumes after 14 days of treatment. The primary safety outcome was severe adverse events (SAEs) for 90 days. RESULTS: There were 57 and 60 patients finally included in the ANP and placebo groups, respectively for modified intention-to-treat analysis. The median age was 66.0 years, and the median NIHSS score at baseline was 12.0. The changes in cerebral infarct volume at day 14 were 0.3 mL and 0.4 mL in the ANP and placebo groups, respectively (median difference: -7.1 mL; interquartile range [IQR]: -18.3 to 2.3 mL, P = 0.30). The changes in cerebral edema volume of the ANP and placebo groups on day 14 were 11.4 mL and 4.0 mL, respectively ( median difference: 3.0 mL, IQR: -1.3 to 9.9 mL, P = 0.15). The rates of SAE within 90 days were similar in the ANP (3/57, 5%) and placebo (7/60, 12%) groups ( P = 0.36). Changes in serum mercury and arsenic concentrations were comparable. In patients with large artery atherosclerosis, ANP reduced the cerebral infarct volume at 14 days (median difference: -12.3 mL; IQR: -27.7 to -0.3 mL, P = 0.03). CONCLUSIONS: ANP showed a similar safety profile to placebo and non-significant tendency to reduce cerebral infarct volume in patients with moderate-to-severe stroke. Further studies are warranted to assess the efficacy of ANP in reducing cerebral infarcts and improving clinical prognosis. TRAIL REGISTRATION Clinicaltrials.gov , No. NCT04475328.

Diabetic kidney disease （DKD） is the main cause of end-stage renal disease. Its high prevalence， mortality rate， and medical cost bring a heavy economic burden to society and families， and DKD has become one of the most important public health problems. Intestinal microecology is the most important and complex micro-ecosystem in the human body， which is involved in important life activities such as material and energy metabolism， immune system regulation， and signal transduction， thereby maintaining the dynamic balance of the human internal environment. The dynamic balance between the intestinal microecology and the body is essentially a Yin-Yang balance. Once this balance is broken， intestinal microbiota imbalance， intestinal mucosal barrier damage， immune dysfunction， and reduction of metabolite short-chain fatty acids （SCFAs） will occur， which play an important role in the progression of DKD. From the perspective of the Yin-Yang theory of traditional Chinese medicine （TCM）， the imbalance of intestinal microecology in DKD is equivalent to the excessive or insufficient constraint of Yin and Yang， or Yin deficiency affecting Yang， or Yang deficiency affecting Yin， or waning and waxing of Yin and Yang. For different pathogenesis changes， "Yin disease treated through Yang"， "treating Yin for Yang"， or "treating Yang for Yin" methods are adopted to regulate intestinal microbiota， inhibit immune inflammation， protect intestinal mucosal barrier， and increase SCFAs through TCM， thereby reconciling Yin and Yang to achieve the condition where "Yin is at peace and Yang is compact". Based on the Yin-Yang theory， this paper intended to interpret the scientific connotation of TCM in the treatment of DKD with intestinal microecology as the target and TCM in the treatment of DKD by regulating intestinal microecology as the breakthrough point to provide a novel insight for the occurrence and development of DKD and the mechanism of TCM.

【Objective】 To explore the therapeutic effect of autologous platelet-rich plasma (PRP) in the treatment of patellofemoral osteoarthritis (PFOA) based on the Magnetic Resonance Observation of Cartilage Repair Tissue 2.0 (MOCART 2.0) knee score system. 【Methods】 A total of 22 patients (28 knees) with PFOA treated by intraarticular PRP injection in our hospital from January 2020 to December 2023 were enrolled in the study. The nuclear magnetic resonance(NMR) images before and after treatment were compared using the MOCART 2.0 knee score system. Visual Analog Scales (VAS) score and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score before and after treatment were evaluated and compared, and adverse reactions were observed during the treatment. 【Results】 The MOCART 2.0 knee score showed no difference before and after treatment (53.4±12.2 vs 49.9±2.1)(P>0.05). In the subgroup analysis, the "signal intensity of the repair tissue" score and the "subchondral changes" score were better than those before treatment as(5.5±1.5)vs(4.6±1.5)and(15.9±4.3)vs(13.2±6.4)(P<0.05). There were no significant changes in indicators as " degree of cartilage filling" , " integration with adjacent cartilage edges" , " repair of tissue surface structure" , " repair of tissue structure" and " bone changes" (P>0.05).The VAS score and WOMAC score gradually decreased at 1 month, 3 months and 6 months after treatment and were better than before treatment (P<0.05). Incidence of adverse reactions was 4% (4/112). 【Conclusion】 Intraarticular PRP injection is an effective and safe option for treatment of PFOA, and can improve the cartilage signal intensity and alleviating subchondral bone edema.

【Objective】 To explore the model of treatment of refractory wounds by apheresis platelet-rich plasma (PRP), and evaluate its efficacy and safety. 【Methods】 PRP treatment was carried out for 34 patients with refractory wounds who were hospitalized in our hospital from June 2020 to December 2023. The patient′s autologous PRP was collected by the blood composition separator. PRP point-like injection and/or direct application along the edge of the wound, or platelet gel (PG) to cover the wound and fill the sinus were used to treat different types of wounds. The frequency of treatment was once to twice a week, with each course of treatment consisting of 4 to 5 sessions. The efficacy was observed and recorded, and the safety was evaluated. 【Results】 Before PRP collection, the basal platelet, white blood cell and red blood cell counts were (321.85±114.64) ×10⁹/L, (9.52±3.21) ×10⁹/L and (4.34±0.62) ×10¹²/L, respectively. The counts of platelets, white blood cells and red blood cells in PRP products were (1 438.53±376.89)×10⁹/L, (1.38±1.03)×10⁹/L and (0.03±0.01)×10¹²/L, respectively. The platelet concentration of PRP products increased by 4.47 times on average, and the sampled bacterial culture was negative. Out of 34 patients treated with PRP, 33 showed improvement in symptoms, while 1 did not respond well due to long-term bedridden and poor compliance. Four patients had mild adverse reactions during PRP collection or treatment, but all were able to complete PRP collection or treatment after standardized treatment. 【Conclusion】 Apheresis PRP products have the advantages of stable quality, safety, reliability and traceability, and can effectively promote the healing of a variety of refractory wounds. Its treatment process is safe and effective, and is worthy of popularization and application.

OBJECTIVE To study the inhibitory effect and mechanism of curcumin and its derivatives A and B on TGF-β induced LX-2 cell fibrosis. METHODS Established the liver fibrosis model of LX-2 cells induced by TGF-β(10 ng·mL−1).The effects on cell proliferation were detected by CCK-8. The effects on cell apoptosis was detected by flow cytometry. The effects on fibrosis related factors(Collagen I, Collagen Ⅳ, Fibronectin, Vimentin, α-SMA, PDGFRβ, TGFβR1, TGFβR2, MMP2, MMP9, TIMP1 and TIMP2) protein expression and gene transcription levels were detected by Western blotting and q-PCR. RESULTS The curcumin and its derivative A and B had the inhibition effects on normal LX-2 cells, and the IC25 values were 15.7, 2.6, 10.2 μmol·L−1, respectively. Compared to the model group, the curcumin(15.7 μmol·L−1) and its derivative A(2.6 μmol·L−1) and B(10.2 μmol·L−1) had the significant inhibition effects on cell proliferation of the TGF-β induced LX-2 cells(P<0.05). The cell apoptosis rate of curcumin derivative B group was higher than the model group(P<0.05). Collagen I, Fibronectin, Vimentin, α-SMA, TGFβR1 and TIMP-1 protein expression levels in curcumin group were lower, while the protein expression level of MMP-9 was higher(P<0.05). The protein expression levels of Collagen I, Collagen IV, Fibronectin, Vimentin, α-SMA, TIMP-1 and TIMP-2 in curcumin derivative A group were lower, while the protein expression level of MMP-2 was higher(P<0.05). The protein expression levels of Collagen I, Collagen IV, Fibronectin, Vimentin, α-SMA, PDGFRβ, TGFβR1, TGFβR2, TIMP-1 and TIMP-2 in curcumin derivative B group were lower, while the protein expression level of MMP-2 was higher(P<0.05). The gene transcription levels of Collagen I, Fibronectin, α-SMA and TIMP-1 in curcumin group were lower(P<0.05). The gene transcription levels of Collagen I, Fibronectin and α-SMA in curcumin derivative A and B groups were lower(P<0.05). CONCLUSION Curcumin and its derivatives A and B inhibit the abnormal activation and proliferation of TGF-β-induced LX-2 cells, inhibit the excessive secretion and accumulation of its extracellular matrix components, and promote its degradation, thus playing an anti-fibrotic effect in vitro, especially the curcumin derivative B.
