OBJECTIVE: To evaluate the efficacy and safety of DCAG (decitabine, cytarabine, anthracyclines, and granulocyte colony-stimulating factor) regimen in the treatment of patients with relapsed/refractory (R/R) acute myeloid leukemia (AML). METHODS: The clinical data of 64 R/R AML patients received treatment at Chinese PLA General Hospital from January 1st, 2012 to December 31st, 2022 were retrospectively analyzed. Primary endpoints included efficacy measured by overall response rate (ORR) and safety. Secondary endpoints included overall survival (OS), event-free survival (EFS) and duration of response (DOR). The patients were followed from enrollment until death, or the end of last follow-up (June 1st, 2023), whichever occurred first. RESULTS: Sixty-four patients who failed prior therapy were enrolled and completed 1 cycle, and 26 and 5 patients completed 2 and 3 cycles, respectively. Objective response rate was 67.2% ［39: complete remission (CR)/CR with incomplete hematologic recovery (CRi), 4: partial remission (PR)］. With a median follow-up of 62.0 months (1.0-120.9), the median overall survival (OS) was 23.3 and event-free survival was 10.6 months. The median OS was 51.7 months (3.4-100.0) in responders (CR/CRi/PR) while it was 8.4 months (6.1-10.7) in nonresponders ( P <0.001). Grade 3-4 hematologic toxicities were observed in all patients. Four patients died from rapid disease progression within 8 weeks after chemotherapy. CONCLUSION The DCAG regimen represents a feasible and effective treatment for R/R AML.

BACKGROUND: Our understanding of the correlation between postdischarge cancer and mortality in patients with coronary artery disease (CAD) remains incomplete. The aim of this study was to investigate the relationships between postdischarge cancers and all-cause mortality and cardiovascular mortality in CAD patients. METHODS: In this retrospective cohort study, 25% of CAD patients without prior cancer history who underwent coronary artery angiography between January 1, 2011 and December 31, 2015, were randomly enrolled using SPSS 26.0. Patients were monitored for the incidence of postdischarge cancer, which was defined as cancer diagnosed after the index hospitalization, survival status and cause of death. Cox regression analysis was used to explore the association between postdischarge cancer and all-cause mortality and cardiovascular mortality in CAD patients. RESULTS: A total of 4085 patients were included in the final analysis. During a median follow-up period of 8 years, 174 patients (4.3%) developed postdischarge cancer, and 343 patients (8.4%) died. A total of 173 patients died from cardiovascular diseases. Postdischarge cancer was associated with increased all-cause mortality risk (HR = 2.653, 95% CI: 1.727-4.076, P < 0.001) and cardiovascular mortality risk (HR = 2.756, 95% CI: 1.470-5.167, P = 0.002). Postdischarge lung cancer (HR = 5.497, 95% CI: 2.922-10.343, P < 0.001) and gastrointestinal cancer (HR = 1.984, 95% CI: 1.049-3.750, P = 0.035) were associated with all-cause mortality in CAD patients. Postdischarge lung cancer was significantly associated with cardiovascular death in CAD patients (HR = 4.979, 95% CI: 2.114-11.728, P < 0.001), and cardiovascular death was not significantly correlated with gastrointestinal cancer or other types of cancer. CONCLUSIONS Postdischarge cancer was associated with all-cause mortality and cardiovascular mortality in CAD patients. Compared with other cancers, postdischarge lung cancer had a more significant effect on all-cause mortality and cardiovascular mortality in CAD patients.

Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.

As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

OBJECTIVE: To analyze the kinetic characteristics of lymphocyte subsets and myeloid-derived suppressor cell (MDSC) in patients who newly diagnosed intermediate- to high-risk aGVHD and treated with steroids-ruxolitinib as the first line therapy from a single-arm, open clinical trial (NCT04061876). METHODS: We prospectively observed the efficacy of 23 patients having intermediate- to high-risk aGVHD and treated with steroids-ruxolitinib as the first line therapy. The kinetic characteristics of lymphocyte subsets and MDSC were monitored, and then we compared them in steroids-ruxolitinib group (n=23), free-aGVHD group (n=20) and steroids group (n=23). RESULTS: Of the 23 patients, the CR rate was 78.26% (18/23) on day 28 after first-line treatment with steroids-ruxolitinib. On day 28 after treatment, patients had lower level of CD4⁺CD29⁺ T cells (P=0.08) than that of pre-treatment, whereas levels of other lymphocyte subsets in this study were higher than that of pre-treatment; CD4⁺CD29⁺ T cells in CR patients decreased, compared with refractory aGVHD patients. On day 28 of treatment, CD8⁺CD28^- T cells (P=0.03) significantly increased in patients with aGVHD than that in patients without aGVHD, so did CD8⁺CD28^- T / CD8⁺CD28⁺ T cell ratio (P=0.03). Compared with patients without aGVHD, patients with aGVHD had lower level of G-MDSC, especially on day 14 after allo-HSCT (P=0.04). Compared with pre-treatment, M-MDSC was higher in CR patients on day 3 and 7 post-treatment (P₃=0.01, P₇=0.03), e-MDSC was higher on day 28 post-treatment (P=0.01). Moreover, compared with CR patients, M-MDSC was lower in refractory aGVHD patients on day 3 post-treatment (P=0.01) and e-MDSC was lower on day 28 post-treatment (P=0.01). Compared with steroids group, MDSC in steroids-ruxolitinib group was higher, with the most significant difference in M-MDSC (P₃=0.0351; P₇=0.0142; P₁₄=0.0369). CONCLUSION We found that patients newly diagnosed intermediate- to high-risk aGVHD receiving first-line therapy with steroids-ruxolitinib achieved high response rate. Moreover, the novel first-line therapy has a small impact on the immune reconstitution of patients after allo-HSCT. Elevated MDSC might predict a better response in aGVHD patients receiving this novel first-line therapy. M-MDSC responded earlier to steroids-ruxolitinib than e-MDSC, G-MDSC.

ObjectiveTo investigate the possible mechanism of Bushen Zhuyun prescription （BSZYP） to reduce the level of ovarian apoptosis in Brown Norway （BN） rats with luteal phase deficiency （LPD）. MethodFifty SPF female BN rats were randomly divided into a model group， a dydrogesterone group （0.002 g·kg^-1）， and a low （4.5 g·kg^-1）， a medium （9 g·kg^-1）， and a high-dose （18 g·kg^-1） BSZYP groups， with ten rats in each group. The rats were administrated with corresponding drugs by gavage， once a day for three estrus cycle. Western blot was used to detected the protein expression levels of c-Jun NH2 terminal kinase （JNK）， extracellular signal-regulated kinase （ERK）， phosphorylated-ERK （p-ERK）， phosphorylated-JNK （p-JNK）， p38 mitogen-activated protein kinase （p38 MAPK）， phosphorylated-p38 MAPK （p-p38 MAPK ）， B-cell lymphoma （Bcl-2）， and Bcl-2 associated X protein （Bax） in ovary. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression levels of ERK， JNK， p38 MAPK， Bax， and Bcl-2 in ovary. Enzyme-linked immunosorbent assay （ELISA） was used to detect the serum progesterone （P） and estradiol （E₂） levels. Hematoxylin-eosin （HE） staining was used to observe the ovarian tissue morphology. ResultCompared with the model group， the recovery of estrus cycle of rats in all BSZYP groups had statistical significance after 1-circle administration （P<0.05）. The ovarian tissue morphology in the low-dose BSZYP group was improved， and that in the medium and high-dose BSZYP groups was significantly improved with clear follicle， less vesicular follicle and atretic follicle， and more granular layers. The number of luteum， especially the fresh luteum， in the medium and high-dose groups was increased with smooth edge and large volume. The mRNA expression level of Bcl-2 was increased in all-dose BSZYP groups， while the mRNA expression level of Bax was significantly decreased in all-dose BSZYP group （P<0.05， P<0.01）. The mRNA expression levels of JNK and p38 MAPK were significantly decreased in the high-dose BSZYP group （P<0.01）， and the mRNA expression levels of ERK were increased in the low and medium-dose BSZYP groups （P<0.05）. The protein expression level of Bcl-2 was significantly increased in the medium and high-dose BSZYP groups （P<0.01）， and the protein expression level of Bax was significantly decreased in the all-dose BSZYP groups （P<0.01）. No significant difference was observed in the protein expressions of JNK， ERK， and p38 MAPK in the BSZYP groups. The protein expression levels of p-ERK in the ovarian tissues of rats were significantly inoreased in the medium and high-dose BSZYP group （P<0.01）， p-JNK， and p-p38 MAPK in the ovarian tissues of rats were significantly decreased in the medium and high-dose BSZYP group （P<0.01）. The level of E₂ was increased in all-dose BSZYP groups （P<0.05， P<0.01）， and the level of P in the medium-dose BSZYP group was increased （P<0.05）. ConclusionBSZYP improved the serum sex hormones， restored the estrous cycle， reduced atretic follicle and vesiculation， and maintained luteal morphology and function of BN rats， so as to improve luteal function and treat luteal phase deficiency. The mechanism of BSZYP may be related to reduce the level of ovarian tissue apoptosis in BN rats by regulating MAPKs signaling pathway.

Aim To investigate the effects of combined administration of loganin and berberine on bone structure and metabolism in diabetic mice and its potential mechanism.Methods The diabetic ICR mouse model was induced by high fat diet(HFD).After 10 weeks of combined intervention, the effects of loganin and berberine on body weight, body fat rate, blood glucose, blood lipid and serum oxidative stress levels were observed.Bone microstructure was scanned by micro-CT.Biomechanical characteristics of bone were measured by three-point bending test, and material properties were detected by fourier transform infrared(FTIR).The pathological changes were observed by HE and TRAP staining.Protein expressions involved in advanced glycation end products(AGEs)and their receptors(RAGE)/nuclear factor-κB(NF-κB)signaling pathway were detected by immunohistochemistry.Results The combined administration of loganin and berberine could significantly inhibit the weight gain, reduce the levels of blood glucose, blood lipid and oxidative stress, as well as improve glucose tolerance.In addition, combined intervention also decreased the expression levels of the proteins involved in AGEs/RAGE/NF-κB signaling pathway, and improved bone microstructure, finally contributing to increasing bone quality in diabetic mice.Conclusions The combination of loganin and berberine could improve bone metabolism in diabetic mice, which may be related to AGEs/RAGE/NF-κB signaling pathway.
