The efficacy of Xiangmei Pills on rats with ulcerative colitis(UC) was investigated by characterizing the spectrum of the active chemical components of Xiangmei Pills. Rapid identification and classification of the main chemical components were performed,and the therapeutic effects of Xiangmei Pills on the proteins and intestinal flora of UC rats were analyzed to explore the mechanism of its action in treating UC. Fifty SD rats were acclimatized to feeding for 3 d and randomly divided into blank group, model group,mesalazine group(0. 4 g·kg~(-1)), low-dose group of Xiangmei Pills(1. 89 g·kg~(-1)), and high-dose group of Xiangmei Pills(5. 67 g·kg~(-1)), with 10 rats in each group. 5% dextrose sodium sulfate(DSS) was given by gavage to induce the male SD rat model with UC,and the corresponding medicinal solution was given by gavage after 10 days, respectively. The therapeutic effect of Xiangmei Pills on rats with UC was evaluated according to body mass, disease activity index(DAI), and hematoxylin-eosin(HE) staining, and the histopathological changes in the colon were observed. Ultra-high performance liquid chromatography-quadrupole/electrostatic field orbitrap high-resolution mass spectrometry(UHPLC-Q-Orbitrap HRMS) technique was used to rapidly and accurately identify the main chemical constituents of Xiangmei Pills. Immunohistochemistry was used to detect the expression of aryl hydrocarbon receptor(AhR),interferon-γ(IFN-γ), mucin-2(MUC-2), and cytochrome P450 1A1(CYP1A1) in colon tissue. Interleukin-22(IL-22) expression in colon tissue was detected by immunofluorescence. The 16S r DNA high-throughput sequencing technique was used to study the modulatory effects of Xiangmei Pills on the intestinal flora structure of rats with UC. Pharmacodynamic results showed that compared with that of the blank group, the colon tissue of the model group was congested, and ulcers were visible in the mucosa; compared with that in the model group, the histopathology of the colon of the rats with UC in the groups of Xiangmei Pills were improved, with scattered ulcers and reduced inflammatory cell infiltration. Chemical analysis showed that a total of 45 components were identified by mass spectrometry information, including 15 phenolic acids, 8 coumarins, 15 organic acids, 3 amino acids, 2 flavonoids, and 2 other components. Compared with those in the blank group, the levels of Ah R, CYP1A1, MUC-2, and IL-22 proteins in the colon tissue of rats in the model group were significantly decreased, and the level of IFN-γ protein was significantly increased; the intestinal flora of rats in the model group was disorganized, with a decrease in the abundance of the flora; the relative abundance of Bacteroidetes,unclassified genera of Ascomycetes, Prevotella of the Prevotella family, and Prevotella decreased significantly, and that of Firmicutes decreased, but the difference was not statistically significant. The relative abundance of Bacteroidetes, Bifidobacterium, and Lactobacillus increased significantly. Compared with those of the model group, the levels of Ah R, CYP1A1, MUC-2, and IL-22proteins in the colonic tissue of the groups of Xiangmei Pills were significantly higher, and the levels of IFN-γ proteins were significantly lower. The recovery of the intestinal flora was accelerated, and the diversity of the intestinal flora was significantly increased. The relative abundance of Bacteroidetes was significantly increased, and that of unclassified genera of Ascomycetes,Lactobacillus, Prevotella of the Prevotella family, and Prevotella was significantly increased. The relative abundance of Bacteroidetes and Bifidobacterium was significantly decreased. This study demonstrated that Xiangmei Pills can effectively treat UC, mainly through the phenolic acid and organic acid components to stimulate the intestinal barrier, regulate protein expression and the relative abundance and diversity of intestinal flora, and play a role in the treatment of UC.

Objective: To explore the influencing covariates of severe neutrophils and/or thrombocytopenia and their effect on treatment response and outcome in patients with chronic-phase chronic myeloid leukemia (CP-CML) receiving initial second-generation tyrosine kinase inhibitors (2G-TKI) . Methods: Data from consecutive patients aged ≥18 years with newly diagnosed CP-CML who received initial 2G-TKI at Peking University People's Hospital from September 2008 to November 2021 were interrogated. Binary logistic regression models and Fine-Gray and Cox regression models were applied. Results: Data from 267 patients who received initial 2G-TKI, including nilotinib (n=239, 89.5% ) and dasatinib (n=28, 10.5% ) , were interrogated. The median age was 36 (range, 18-73) years, and 156 (58.4% ) patients were male. At a median treatment period of 1.0 (0.1-3.0) month, 43 (16.1% ) patients developed grade ≥3 neutrophils and/or thrombocytopenia and recovered within 1.0 (0.1-24.6) month. Male (OR=2.9, 95% CI 1.2-6.8; P=0.018) , age of ≥36 years (OR=3.2, 95% CI 1.4-7.2, P=0.005) , a spleen below a costal margin of ≥7 cm (OR=2.8, 95% CI 1.2-6.6, P=0.020) , and a hemoglobin (HGB) level of <100 g/L (OR=2.9, 95% CI 1.3-6.8, P=0.012) at diagnosis were significantly associated with grade ≥ 3 neutrophils and/or thrombocytopenia. Based on their regression coefficients, male, age of ≥36 years, a spleen below a costal margin of ≥7 cm, and an HGB level of <100 g/L were given 1 point to form a predictive system. All patients were divided into three risk subgroups, and the incidence of severe cytopenia significantly differed among the three groups (P < 0.001) . Grade ≥3 neutrophils and/or thrombocytopenia for >2 weeks was significantly associated with lower cumulative incidences of complete cytogenetic response (CCyR, HR=0.5, 95% CI 0.3-0.7, P<0.001) and major molecular response (MMR, HR=0.4, 95% CI 0.3-0.8, P=0.004) and was not significantly associated with failure, progression, and survival. Conclusion: Male, advanced age, a large spleen, and a low HGB level were significantly associated with severe cytopenia. The four covariates were used to establish a prediction model, in which the incidence of severe cytopenia among different risk groups was significantly different. Severe cytopenia for >2 weeks was a negative factor for responses but not for outcomes.

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

Objective: To explore the efficacy and prognosis of nilotinib or dasatinib as second- or third-line treatment in patients with chronic myeloid leukemia (CML) in the chronic phase (CP) and accelerated phase (AP) . Methods: From January 2008 to November 2018, the data of CML patients who failed first- or second-line tyrosine kinase inhibitor (TKI) -therapy received nilotinib or dasatinib as second-line and third-line therapy were retrospectively reviewed. Results: A total of 226 patients receiving nilotinib or dastinib as second-line (n=183) and third-line (n=43) therapy were included in this study. With a median follow-up of 21 (range, 1-135) months, the cumulative rates of complete hematological response (CHR) , complete cytogenetic response (CCyR) and major molecular response (MMR) were 80.4%, 56.3%and 38.3%, respectively in those receiving TKI as second-line TKI therapy. The 3-year progression-free survival (PFS) and overall survival (OS) rates were 78.7%and 93.1%, respectively. Multivariate analyses showed that Sokal high risk, female gender, the best response achieved The efficacy of dasatinib and nilotinib as second- or third-line TKI-therapy were active in the CML patients with TKI-resistance. The best response achieved on previous TKI-therapy, the disease phase before switching TKI, and the severe hematologic toxicity developing on the current TKI-therapy were associated with the responses and outcomes.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

Objectives: To compare the efficacy and safety of Chinese generic imatinib with branded imatinib as frontline therapy in adults with newly diagnosed chronic myeloid leukemia in chronic phase (CML-CP) (Frontline group) , and to explore the efficacy and safety of Chinese generic imatinib in CML-CP patients switching from branded imatinib (Switching group) . Methods: Frontline group: Data of adults with newly diagnosed CML-CP receiving Chinese generic imatinib (Xinwei(®)) or branded imatinib (Glivec(®)) between October 2013 and August 2018 were retrospectively collected and analyzed. Switching group: Data of adults diagnosed with CML-CP who received branded imatinib and then switched to Chinese generic imatinib after achieving at least complete cytogenetic response (CCyR) were retrospectively collected and analyzed. Results: Frontline group: In total, 409 adult patients receiving Chinese generic imatinib (n=201) or Glivec (n=208) were included in this study. Median age was 42 years (range, 18-83 years) . Comparison of baseline showed significant difference on demographic characteristics among two cohorts: lower education level (P<0.001) , and divorced or widowed status (P=0.004) and rural household registration (P<0.001) were more common in the generic imatinib cohort than those in the Glivec cohort. There was no significant difference on age, gender, Sokal risk score, WBC and HGB between the 2 cohorts. With a median follow-up of 25 months (range, 3-62 months) , there was no significant difference on the 3-year cumulative incidence of achieving CCyR (97.5% vs 94.5%, P=0.592) , major molecular response (MMR) (84.3% vs 93.1%, P=0.208) , molecular response(4.0) (MR(4.0)) (42.7% vs 41.7%, P=0.277) , molecular response(4.5) (MR(4.5)) (25.4% vs 33.0%, P=0.306) as well as the 3-year probabilities of failure free survival (FFS) (76.7% vs 81.0%, P=0.448) , progression free survival (PFS) (91.8% vs 96.3%, P=0.325) and overall survival (OS) (95.8% vs 98.5%, P=0.167) between the generic and branded imatinib cohorts. Multivariate analysis showed the type of imatinib was not associated with treatment responses and outcomes. The incidences of adverse effects were comparable in the 2 cohorts. Switching group: In total, 39 patients switching from branded imatinib to Chinese generic imatinib after achieving at least CCyR were included in this study. Median age was 42 years (range, 23-80 years) . With a median follow-up of 39 months (range, 6-63 months) , molecular responses were maintained in 23 (58.9%) patients and improved in 12 (39.8%) patients. Adverse effects were tolerable. Conclusion: Demographic characteristics might influence the choice of the type of TKI used in CML-CP patients. There was a comparable efficacy and safety between the Chinese generic imatinib and the branded imatinib in adults with newly diagnosed CML-CP under standard management and closely monitoring. Patients could safely switch from the branded imatinib to the Chinese generic imatinib.

Objective: To explore Fertility and disease outcomes in patients with chronic myeloid leukemia (CML) . Methods: Clinical and fertility outcomes of male (from Jul. 1998 to Feb. 2018) and female CML (from Sep. 2009 to Feb. 2018) patients were retrospectively analyzed at Peking University People's Hospital. Results: A total of 49 male CML patients and their spouses were enrolled. Before their spouses conceived, 34 patients were receiving tyrosine kinase inhibitor (TKI) imatinib, 9 with nilotinib, and 6 with dasatinib. At the time of conception, the median age of these male patients was 32 years (range, 25-48 years) , and the median TKI treatment duration was 36 months (range, 0.2-198 months) . One male patient having achieved complete hematologic response yet discontinuing TKI for a year developed a disease progression to blast crisis. The other 48 patients sustained stable disease. The total conception times were 61 and finally 55 infants were born including one with premature birth, two with low birth weight, and one with hypospadias receiving surgery. The other 18 female patients after pregnancy were enrolled. Two patients developed spontaneous abortions. Two received induced abortions. Fourteen gave birth to healthy infants without congenital malformation. The interval from diagnosis of CML to initiation of TKI was 4 months (range, 0.3-16 months) . During a median follow-up of 45 months (range from 7-114 months) , the estimated complete cytogenetic response (CCyR) rate, major molecular response (MMR) rate and molecular response(4.5) (MR(4.5)) rate by 5 years were 88.9%, 85.3% and 35.1%, respectively. The estimated failure-free survival, progression-free survival and overall survival were 64.2%, 90.9% and 90.9%, respectively. All 14 babies developed as normal. Conclusions: It seems that TKIs do not affect pregnancy outcome in the spouses of male CML patients, suggesting that withdrawal of TKIs is not necessary. Female CML patients have good pregnancy and disease outcomes in the TKI era.
