Testicular radiation injury is a structural and functional abnormality of the testes caused directly or indirectly by radiation, which disrupts spermatogenesis and compromises male fertility. The development of effective preventive and therapeutic interventions is essential because of the high prevalence of this condition in clinical settings and its profound effect on patients′ reproductive health and overall well-being. The concept of "the struggle between vital qi and pathogen" is first seen in the Treatise on Cold Pathogenic Diseases. It denotes the dynamic struggle between vital and pathogenic qi. The occurrence, development, and sequelae of all diseases reflect this ongoing conflict. In this context, this study defines the "vital qi" of the testis as its capacity to generate and preserve the essence of reproduction and to resist damage. The pathogenic qi associated with testicular radiation injury is categorized into two types: ionizing poison and retaining evil. The pathogenesis of testicular radiation damage is delineated into three stages by integrating the characteristics of vital and pathogenic qi: the injury, adhesion, and recovery phases. Based on the theoretical framework advanced by this study, the therapeutic approach for testicular radiation injury should adhere to the fundamental principle of strengthening vital qi and eliminating pathogenic factors. Although the primary focus of treatment should be on strengthening vital qi, it should also be complemented by strategies to eliminate pathogenic influences. This paper aims to provide a novel perspective and strategic approach to the traditional Chinese medicine diagnosis, prevention, and treatment of testicular radiation injury. By elucidating the process of testicular radiation injury and its corresponding treatment principles, it seeks to offer valuable insights for clinical practice.

Objective To explore the application of plasma 7 microRNA (miR7) testing in the differential diagnosis of very early-stage hepatocellular carcinoma (HCC). Methods This study is a multicenter real-world study. Patients with single hepatic lesion (maximum diameter≤2 cm) who underwent plasma miR7 testing at Zhongshan Hospital, Fudan University, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Anhui Provincial Hospital, and Peking University People’s Hospital between January 2019 and December 2024 were retrospectively enrolled. Patients were divided into very early-stage HCC group and non-HCC group, and the clinical pathological characteristics of the two groups were compared. The value of plasma miR7 levels, alpha-fetoprotein (AFP), and des-gamma-carboxy prothrombin (DCP) in the differential diagnosis of very early-stage HCC was evaluated using receiver operating characteristic (ROC) curves and area under the curve (AUC). In patients with both negative AFP and DCP (AFP<20 ng/mL, DCP<40 mAU/mL), the diagnostic value of plasma miR7 for very early-stage HCC was analyzed. Results A total of 64 528 patients from 4 hospitals underwent miR7 testing, and 1 682 were finally included, of which 1 073 were diagnosed with very early-stage HCC and 609 were diagnosed with non-HCC. The positive rate of miR7 in HCC patients was significantly higher than that in non-HCC patients (67.9% vs 24.3%, P<0.001). ROC curves showed that the AUCs for miR7, AFP, and DCP in distinguishing HCC patients from the non-HCC individuals were 0.718, 0.682, and 0.642, respectively. The sensitivities were 67.85%, 43.71%, and 44.45%, and the specificities were 75.70%, 92.78%, and 83.91%, respectively. The pairwise comparison of AUCs showed that the diagnostic efficacy of plasma miR7 detection was significantly better than that of AFP or DCP (P<0.05). Although its specificity was slightly lower than AFP and DCP, the sensitivity was significantly higher. Among patients negative for both AFP and DCP, miR7 maintained an AUC of 0.728 for diagnosing very early-stage HCC, with 67.82% sensitivity and 77.73% specificity. Conclusions Plasma miR7 testing is a potential molecular marker with high sensitivity and specificity for the differential diagnosis of small hepatic nodules. In patients with very early-stage HCC lacking effective molecular markers (negative for both AFP and DCP), miR7 can serve as a novel and effective molecular marker to assist diagnosis.

Objective:To investigate and analyze the status quo and risk factors of swallowing function and safe eating behavior in elderly type 2 diabetes patients with frailty, so as to provide a reference for clinical early identification and early prevention.Methods:From July 2021 to December 2022, 295 patients with type 2 diabetes accompanied with frailty were selected from the Endocrinology Department of Beijing Friendship Hospital Affiliated to Capital Medical University by convenience sampling. Patients were surveyed using the Tilburg Frailty Indicator (TFI) and the Eating Assessment Tool-10. Single factor analysis and Logistic regression analysis were used to explore the influencing factors of swallowing function and safe eating behavior in elderly type 2 diabetes patients with frailty.Results:A total of 295 questionnaires were distributed, and 291 valid questionnaires were collected, with an effective response rate of 98.64%. There were 94 cases in the group with abnormal swallowing function and safe eating behavior, and 197 cases in the group with normal swallowing function and safe eating behavior. There were statistical differences in age, body mass index, duration of diabetes, TFI score, education level, and number of chronic diseases between the two groups ( P<0.05). Logistic regression analysis showed that the duration of diabetes ( OR=1.047, P=0.024), TFI score ( OR=1.147, P=0.009), and the number of chronic diseases ( OR=1.282, P=0.035) were the influencing factors of swallowing function and safe eating behavior in elderly type 2 diabetes patients with frailty. Conclusions:Abnormal swallowing function and safe eating behavior are common in elderly type 2 diabetes patients with frailty, and the duration of diabetes, frailty and chronic comorbidity are independent risk factors.

Chinese Journal of Microbiology and Immunology 2024;44(10):838-852
Objective:To explore the differences in gut microbiota and immune factors in fecal lysate of children with different clinical subtypes of Mycoplasma pneumoniae pneumonia (MPP). Methods:Children aged 3-14 years with MPP who visited Shanghai Ninth People′s Hospital from March 2023 to February 2024 were selected and divided into general group (GMPP group) and severe group (SMPP group) based on the severity of the condition. They were also divided into non-refractory group (NRMPP group) and refractory group (RMPP group) based on treatment response. 16S rRNA sequencing was used to analyze the characteristics of gut microbiota, and MSD electrochemiluminescence method was used to determine the levels of immune factors in fecal lysate. Differences in the clinical characteristics, gut microbiota, and fecal immune factors were analyzed. Spearman correlation analysis was performed. Receiver operating characteristic(ROC) curve was used to analyze the evaluation and predictive value of gut microbiota in clinical classification of MPP.Results:Among the 64 children with MPP, there were 34 cases in the GMPP group and 30 cases in the SMPP group. There were statistically significant differences between the two groups in terms of fever duration, presence or absence of hypoxemia, C-reactive protein(CRP), D-Dimer, and chest CT scores ( t=-4.94, P<0.001; χ2=5.33, P=0.021; z=-2.93, P=0.003; z=-3.93, P<0.001; z=-4.10, P<0.001). Among the 64 children with MPP, there were 50 cases in the NRMPP group and 14 cases in the RMPP group. There were statistically significant differences in age, fever duration, and chest CT scores between the two groups ( t=-3.21, P=0.002; t=-5.28, P<0.001; z=-2.95, P=0.003). There was no statistically significant difference in the alpha diversity analysis of gut microbiota between GMPP group and SMPP group( P>0.05). There was a statistically significant difference in beta diversity analysis between the two groups of gut microbiota ( R2=0.06, P=0.001). Species difference analysis showed that the relative abundance of Bifidobacterium in the SMPP group was significantly lower than that in the GMPP group, while the relative abundance of Blautia and Ruminococcus gnavus was significantly higher than that in the GMPP group, with statistical significance ( z=5.21, P<0.001, Q=0.039; z=1.56, P<0.001, Q=0.039; z=2.08, P=0.007, Q=0.700). There was no statistically significant difference in the alpha diversity analysis of gut microbiota between NRMPP and RMPP group( P>0.05). There was a statistically significant difference in beta diversity analysis between the two groups of gut microbiota ( R2=0.05, P=0.001). Analysis of species differences showed that the relative abundance of Bifidobacterium and Subdoligranulum in the RMPP group was significantly lower than that in the NRMPP group, while the relative abundance of Blautia and Ruminococcus gnavus was significantly higher than that in the NRMPP group, with statistical significance( z=3.44, P=0.012, Q=0.638; z=3.64, P=0.040, Q=0.638; z=5.80, P=0.001, Q=0.338; z=5.46, P=0.015, Q=0.638). The level of fecal immune factors IL-10 and IL-1β were statistically significant between GMPP group and SMPP group( z=-1.96, P=0.050; z=-2.46, P=0.014). The level of fecal immune factors IFN-γ, IL-10, IL-1β, IL-8, and TNF-α were statistically significant between NRMPP group and RMPP group ( z=-2.20, P=0.028; z=-2.17, P=0.030; z=-2.00, P=0.046; z=-2.14, P=0.032; z=-2.22, P=0.027). Sperman correlation analysis showed that Bifidobacterium was negatively correlated with fever duration and chest CT score ( r=-0.35, P=0.005; r=-0.30, P=0.017); Blautia was positively correlated with D-Dimer, fever duration, and chest CT score ( r=0.33, P=0.008; r=0.37, P=0.003; r=0.40, P=0.001); Ruminococcus gnavus and TNF-α, IL-10, IL-4, and IL-6 were negatively correlated ( r=-0.34, P=0.001; r=-0.29, P=0.021; r=-0.28, P=0.024; r=-0.28, P=0.027). ROC curve analysis showed that the area under curve(AUC) of Bifidobacterium abundance for assessing the severity of MPP was 0.767 (95% CI: 0.649-0.885, P<0.001). The AUC of Blautia abundance for assessing the severity of MPP was 0.774 (95% CI: 0.658-0.889, P<0.001), and the AUC for predicting treatment response to MPP was 0.787 (95% CI: 0.655-0.919, P=0.001). Conclusions:The levels of fecal immune factors vary among children with different clinical subtypes of MPP. The relative abundance analysis of Bifidobacterium and Blautia in the gut microbiota of children with MPP may have certain clinical value for evaluating the severity of MPP, adopting adjuvant therapy, and predicting treatment response.

Identifying the compound formulae-related xenobiotics in bio-samples is full of challenges.Conventional strategies always exhibit the insufficiencies in overall coverage,analytical efficiency,and degree of automation,and the results highly rely on the personal knowledge and experience.The goal of this work was to establish a software-aided approach,by integrating ultra-high performance liquid chromatography/ion-mobility quadrupole time-of-flight mass spectrometry(UHPLC/IM-QTOF-MS)and in-house high-definition MS2 library,to enhance the identification of prototypes and metabolites of the compound formulae in vivo,taking Sishen formula(SSF)as a template.Seven different MS2 acquisition methods were compared,which demonstrated the potency of a hybrid scan approach(namely high-definition data-independent/data-dependent acquisition(HDDIDDA))in the identification precision,MS1 coverage,and MS2 spectra quality.The HDDIDDA data for 55 reference compounds,four component drugs,and SSF,together with the rat bio-samples(e.g.,plasma,urine,feces,liver,and kidney),were acquired.Based on the UNIFI? platform(Waters),the efficient data processing workflows were estab-lished by combining mass defect filtering(MDF)-induced classification,diagnostic product ions(DPIs),and neutral loss filtering(NLF)-dominated structural confirmation.The high-definition MS2 spectral li-braries,dubbed in vitro-SSF and in vivo-SSF,were elaborated,enabling the efficient and automatic identification of SSF-associated xenobiotics in diverse rat bio-samples.Consequently,118 prototypes and 206 metabolites of SSF were identified,with the identification rate reaching 80.51%and 79.61%,respectively.The metabolic pathways mainly involved the oxidation,reduction,hydrolysis,sulfation,methylation,demethylation,acetylation,glucuronidation,and the combined reactions.Conclusively,the proposed strategy can drive the identification of compound formulae-related xenobiotics in vivo in an intelligent manner.
