Radiotherapy (RT) can potentially induce systemic immune responses by initiating immunogenic cell death (ICD) of tumor cells. However, RT-induced antitumor immunologic responses are sporadic and insufficient against cancer metastases. Herein, we construct multifunctional self-sufficient nanoparticles (MARS) with dual-enzyme activity (GOx and peroxidase-like) to trigger radical storms and activate the cascade-amplified systemic immune responses to suppress both local tumors and metastatic relapse. In addition to limiting the Warburg effect to actualize starvation therapy, MARS catalyzes glucose to produce hydrogen peroxide (H₂O₂), which is then used in the Cu⁺-mediated Fenton-like reaction and RT sensitization. RT and chemodynamic therapy produce reactive oxygen species in the form of radical storms, which have a robust ICD impact on mobilizing the immune system. Thus, when MARS is combined with RT, potent systemic antitumor immunity can be generated by activating antigen-presenting cells, promoting dendritic cells maturation, increasing the infiltration of cytotoxic T lymphocytes, and reprogramming the immunosuppressive tumor microenvironment. Furthermore, the synergistic therapy of RT and MARS effectively suppresses local tumor growth, increases mouse longevity, and results in a 90% reduction in lung metastasis and postoperative recurrence. Overall, we provide a viable approach to treating cancer by inducing radical storms and activating cascade-amplified systemic immunity.

The adulteration and counterfeiting of herbal ingredients in medicinal and food homology (MFH) have a serious impact on the quality of herbal materials, thereby endangering human health. Compared to pharmaceutical drugs, health products derived from traditional Chinese medicine (TCM) are more easily accessible and closely integrated into consumers' daily life. However, the authentication of the authenticity of TCM ingredients in MFH has not received sufficient attention. The lack of clear standards emphasizes the necessity of conducting systematic research in this area. This study utilized DNA barcoding technology, combining ITS2, psbA-trnH, matK as universal barcode sequences, and DX, HH, JYH as specific barcode sequences, to identify the authenticity of commercial medicinal and food homology scented herbal teas. The aim was to investigate the authenticity of scented herbal tea products circulating in the market. The research results revealed that among 180 scented herbal tea samples, DNA barcodes were successfully obtained from 164 samples, while the remaining samples either lacked the target components or suffered severe DNA degradation, resulting in failed amplification. Combined with morphological identification studies, it was found that out of the 180 samples, 141 were authentic, accounting for 78.33% of the total samples, while 31 samples showed adulteration and 8 samples lacked the target components, accounting for 21.67% of the total samples. Additionally, water testing revealed that 5 samples of Carthamus tinctorius herbal tea exhibited the phenomenon of weight adulteration. This study exposed the presence of adulteration and weight adulteration in scented herbal tea products, highlighting the need for regulatory authorities to expedite the establishment of quality standards in scented herbal tea industry. These findings provide valuable insights for the rapid development of the scented herbal tea industry.

Gynecological cancer significantly affect the health of women.This review aimed to describe the global patterns and trends in the survival of patients with gynecological cancers.We searched PubMed,Embase,Web of Science,SinoMed,and SEER for survival analyses of cancer registration data of cervical,endometrial,and ovarian cancers published between 1980 and 2022.Globally,the highest 5-year observed survival rate for cervical cancer was 76.5%in Anshan,Liaoning,China(2008-2017).The 5-year observed survival rates of endometrial and ovarian cancers were higher in Finland(1995-1999,82.5%)and Singapore(1988-1992,62.0%).The 5-year relative survival rate of cervical cancer patients was higher in Haining,Zhejiang,China(2011-2014,85.8%).Korea ranked first at 89.0%and 64.5%for endometrial and ovarian cancers,respectively.Survival rates have improved for cervical,endometrial,and ovarian cancers.Patients aged≥75 years and those with advanced-stage disease had the worst 5-year survival rates.Survival rates were better for squamous cell carcinoma in cervical cancer,for endometrial carcinoma and mucinous adenocarcinoma in endometrial cancer,and for germ cell and sex-cord stromal tumors in ovarian cancer.Over the past four decades,the survival rates of gynecological cancers have increased globally,with notable increases in cervical and endometrial cancers.Survival rates are higher in developed countries,with a slow-growing trend.Future studies should focus on improving survival,especially in ovarian cancer patients.

Sepsis-associated encephalopathy (SAE) is the most common neurological complication of sepsis, with an incidence of up to 70% in sepsis, and contributes to the increased mortality and disability in sepsis. To date, the exact pathogenesis of SAE is not clear. Most of current researches indicated that blood-brain barrier (BBB) dysfunction, active neuroinflammation, glial cell over activation as well as cerebral microcirculation dysfunction contributed to the pathophysiology of SAE. BBB, as a complex cellular structure between the central nervous system and the peripheral system, strictly controls the entrance and discharge of substances and plays an important role in maintaining the balance between biochemical system and immune system of central system. During the progress of sepsis, inflammatory cytokines and reactive oxygen species resulting from peripheral system directly or indirectly resulted in the damage to the integrity and structure of BBB, which helped above species easily enter into the central system. Above these damages caused glial cell activation (microglia and astrocyte), the imbalance of neurotransmitters, mitochondrial dysfunction and neural apoptosis, which also reversely contributed to the damage to the integrity and permeability of BBB via decreasing the expression of tight junctional protein between cells. Therefore, this review focuses on the structural and functional changes of BBB in SAE, and how these changes lead to the development of SAE, in order to seek a BBB-targeted therapy for SAE.

Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.

Objective: To describe the clinical features, causal agent and transmission mode of a fever outbreak in a school in Shanghai. Methods: Field epidemiological approaches including case definition development, searching for contacts, distribution of diseases description, environmental sampling and laboratory testing. Results: A total of 16 influenza like cases were included, all concentrated in the one class of grade two, including 15 students and 1 teacher. Among student cases, the incidence rate was 36.59% (15/41), the average age was 7.4 years, the incidence rate was 36.84%(7/19) for boys, 36.36%(8/22) for girls. The clinical course was 5-15 days, with the median of 9 days, and 18.75%(3/16) of the cases stayed studying while sick. The nasopharyngeal swab specimens in 16 cases all tested positive for influenza B, of which 11 tested positive for mycoplasma pneumoniae and 1 case also tested positive for coronavirus OC43. Body temperature, number of mononuclear cells, and treatment time of patients infected with Influenza B and mycoplasma pneumoniae were higher than those of patients infected with influenza B alone( P <0.05). The outbreak lasted for 12 days, all sick students were treated and discharged from hospital, with no severe cases or death, and the outbreak was effectively controlled. Conclusion This campus cluster outbreak caused by influenza B and mycoplasma pneumoniae. Patients with influenza B with mycoplasma pneumoniae have severe symptoms and a long course of illness, suggesting the importance of early management of the epidemic.

The number of investigator initiated research (IIR) is increasing. But the recognition and management of IIR in China is still in its infancy, and there is a lack of specific and operable guidance for the implementation process. Based on our practical experiences, previous literature reports, and current policy regulations, the authors took prospective IIR as an example to summarize the implementation process of IIR into 14 steps, which are as the following: study initiation, ethical review, study registration, study filing, case report form design, database establishment, standard operating procedure making, investigator training, informed consent, data collection, data entry, data verification, data locking and data archiving.

Abstract: Objective　To explore the correlation between monocyte to high-density lipoprotein cholesterol ratio (MHR) and insulin resistance (IR) in male patients with type 2 diabetes mellitus (T2DM) combined with metabolic-related fatty liver disease (MAFLD). Methods A total of 454 male patients with T2DM combined with MAFLD in National Metabolic Management Center (MMC) of the Affiliated Hospital of Jiangsu University from May 2018 to July 2020 were enrolled. The general clinical data of subjects were collected, blood routine and biochemical indexes were tested, homeostasis model insulin resistance index (HOMA-IR) was calculated, visceral fat area (VFA) and subcutaneous fat area (SFA) were measured. Accordingtothe MHR quartile, patients were divided into group Q1 (MHR≤0.38), group Q2 (0.380.64) to compare the differences in measured indicators above. In addition, patients were divided into two groups according to HOMA-IR, HOMA-IR<2.5 and HOMA-IR≥2.5, and the differences in MHR were compared. Results The patients were divided into four groups according to MHR:group Q1 (n=115), group Q2 (n=110), group Q3 (n=120) and group Q4 (n=109). Fasting insulin (FINS) were respectively 6.17(4.20,9.76), 7.73(4.94,10.66), 8.92(5.32,11.33) and 9.13(5.25,12.27) mU/L, 2-hour postprandial insulin were 22.75(12.87,39.59), 27.55(16.44,39.77), 30.98(17.46,43.11) and 31.28(18.54,45.92) U/L. HOMA-IR were 3.12(1.63,4.25), 3.72(2.26,4.66), 3.87(2.48,5.44) and 3.95(2.42,5.31). Neutrophil (Neu) were 3.10(2.60,3.70), 3.20(2.50,3.93), 3.60(2.80,4.28), 4.20(3.30,5.00)×109/L. Subcutaneous fat area (SFA) were (181.27±53.60), (192.64±62.41), (199.53±61.40) and (203.69±71.51) cm2. They all increased gradually. However, the levels of high-density lipoprotein cholesterol (HDL-c) [1.18(1.06,1.35), 1.02(0.86,1.17), 0.96(0.80,1.03) and 0.80(0.69,0.92) mmol/L] and low-density lipoprotein cholesterol (LDL-c) [(3.00±0.79), (2.76±0.83), (2.67±0.85) and (2.59±0.92) mmol/L] decreased gradually. Pearson's or Spearman's correlation analysis showed that MHR was positively correlated with FINS, 2-hour postprandial insulin (2hINS), HOMA-IR, VFA and SFA (r=0.190, 0.153, 0.184, 0.114, 0.127, P<0.05). The coronary heart disease history, systolic blood pressure,diastolic blood pressure,fasting plasmaglucose (FPG), FINS, alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood uric acid (Ur), body mass index (BMI), VFA, SFA and MHR of patients in group HOMA-IR≥2.5 were higher than group HOMA-IR<2.5 (P<0.05). Conclusion　MHR is positively correlated with IR in male patients with T2DM combined with MAFLD, and as MHR increases, the degree of IR is higher.
