Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

BACKGROUNDGroup 2 innate lymphoid cells (ILC2s) are regarded as a novel population of lineage-negative cells that induce innate Type 2 responses by producing the critical Th2-type cytokines interleukin (IL)-5 and IL-13. ILC2s as key players in the development of allergic rhinitis (AR) have been proved, however, the effect of subcutaneous immunotherapy (SCIT) with dermatophagoides pteronyssinus extract (Der p-SCIT) on ILC2s in AR patients is not clear. This study aimed to investigate the response of ILC2s of peripheral blood in house dust mites (HDM)-sensitized Chinese patients with AR who received SCIT with Der P extract.

METHODSSeven healthy controls without symptoms of AR who had negative reactions to any of the allergens from skin-prick testing, nine patients diagnosed with persistent AR according to the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines, and 24 AR patients who received Der p-SCIT for 1.0-3.5 years were recruited for the study. ILC2s in the peripheral blood were evaluated using flow cytometry. The severity of their symptoms of all participants was rated based on the Total 5 symptom score.

RESULTSAmong 40 participants, 9 AR patients were assigned to the untreated group, 24 AR patients receiving Der p-SCIT were assigned to the immunotherapy group, and 7 healthy controls without symptoms of AR were assigned to healthy control group. The mean Total 5 symptom score of immunotherapy group was significantly lower than that of untreated group (4.3 ± 1.4 vs. 10.1 ± 2.5, P< 0.001). Similarly, the levels of ILC2s in the peripheral blood of immunotherapy group were significantly reduced compared with that in untreated group (P < 0.001), but were not significantly different from healthy controls (P = 0.775). Further subgroup analysis based on the duration of SCIT therapy (1.0-2.0 years [SCIT1-2], 2.0-3.0 years [SCIT2-3], and 3.0-3.5 years [SCIT3-3.5]) showed that the percentage of ILC2s was not significantly different between SCIT1-2, SCIT2-3, and SCIT3-3.5groups (SCIT1-2 vs. SCIT2-3: P = 0.268; SCIT1-2vs. SCIT3-3.5: P = 0.635; and SCIT2-3 vs. SCIT3-3.5: P = 0.787).

CONCLUSIONSThe present study highlighted the suppression of Der p-SCIT on ILC2s in HDM-AR patients. ILC2s identified in peripheral blood can be used as an effective biomarker for Der p-SCIT.

OBJECTIVETo evaluate the safety and efficacy between endoscopic papillary balloon dilatation (EPBD) and endoscopic sphincteropapillotomy ( EST) for common bile duct stones using meta-analysis method.

METHODSRandomizd controlled trials comparing EPBD with EST for common bile duct stones and published from January 1990 to July 2012 were recruited. This meta-analysis was conducted to estimate short-term and long-term complications. Fixed random effect model or random effect model was established to analyze the data.

RESULTSTwelve randomizd controlled trials were included in this analysis. These studies included 1865 patients, 925 of them were treated with EPBD and 940 were treated with EST. The analysis of basic characteristics of these included studies showed that: compared to EST, patients in the EPBD group were younger (OR = -1.16, 95% CI: -1.49 to -0.84, P = 0.00), while in two groups, there were no significant difference (P > 0.05) in gender proportion, average size of stones, number of gallstones, previous cholecystectomy, the number of merged duodenal diverticulum, common bile duct diameter, the total follow-up time. Also, compared to EST, the overall stone clearance in the EPBD group was lower (OR = 0.64, 95% CI: 0.42 to 0.96, P = 0.03), pancreatitis incidence was higher (OR = 2.67, 95% CI: 1.61 to 4.43, P = 0.00), incidence of bleeding (OR = 0.12, 95% CI: 0.04 to 0.34, P = 0.00), acute cholecystitis (OR= 0.39, 95% CI: 0.18 to 0.84, P = 0.02), total long-term complication rate (OR = 0.53, 95% CI: 0.36 to 0.77, P = 0.01), stone recurrence rate more than a year were lower (OR= 0.48, 95% CI: 0.26 to 0.90, P = 0.02). While in two groups, there were no significant difference (P > 0.05) in the stone removal on 1 '' attempt, the total near-term complications and acute cholangitis.

CONCLUSIONSOn the basis of lower rates of bleeding, EPBD seems to be preferred strategy over EST for endoscopic remove of common bile duct stones in patients who have coagulopathy. Although stone recurrence rate more than a year of EPBD is lower, but the overall stone clearance rate is lower and the risk of pancreatitis is higher than that of EST.

OBJECTIVETo determine the optimal position of hypoglossal nerve in hypoglossal-facial nerve anastomosis and the eligibility of hypoglossal-facial nerve anastomosis with the cervical loop.

METHODSThe cervical course and adjacent structures of the hypoglossal nerve were observed on 21 adult cadavers. The hypoglossal nerve and facial nerve were taken from 3 fresh specimens, and the number of the fasciculus and the cross-sectional area of the nerve were measured.

RESULTSThe facial nerve trunk were monofascicular with a cross-sectional area of 5.1-/+0.2 (range 4.6-5.7) mm(2). The number of the fasciculus and the cross-sectional areas of the nerve trunk and the fasciculus were 1.6-/+0.8 (range 1-4) mm(2) , 7.5-/+0.7 mm(2) (range 6.8-8.0) mm(2), and 4.7-/+0.6 (4.1-5.5) mm(2), respectively, at the proximal segment of the hypoglossal nerve, 3.6-/+0.5 (1-5) mm(2) , 5.6-/+0.5 (4.9-6.1) mm(2) , and 1.6-/+0.4 (0.9-2.2) mm(2) at the distal segment, and 2.4-/+0.8 (1-3) mm(2), 1.1-/+0.7 (0.6-2.2) mm(2), and 0.5-/+0.3 (0.3-1.2) mm(2) at the cervical loop.

CONCLUSIONThe cervical loop is inadequate for facial nerve anastomosis and the proximal segment is large enough to allow partial harvesting of the hypoglossal nerve for neurotisation of the facial nerve.

OBJECTIVETo evaluate the effect of postoperative adjuvant transcatheter arterial chemoembolization (TACE) on hepatocellular carcinoma (HCC) patients with residual tumor.

METHODSThe patients were classified into intervention group (with adjuvant TACE) and control group (without adjuvant TACE) who were further stratified to those with high risk (patients with single tumor > 5 cm in diameter, or with multiple tumors, invasion to blood vessels), and low risk factors. Univariate analysis and Cox model were used to analyse prognostic factors.

RESULTSIn low risk patients with residual tumor, the 1-, 2-, 3-, 4-year survival rate was 97.2%, 78.0%, 66.5% and 66.5% in the intervention group, and 91.2%, 81.4%, 70.3% and 54.4% in the control group, respectively. There was no statistical difference between the two groups in survival (log-rank P = 0.7667). Comparing with the control group, the 1-, 2-, 3-, 4-year survival rate was 89.5%, 73.4%, 59.2% and 53.8% in the intervention group, and 70.5%, 61.9%, 46.8% and 46.8% in the control group, respectively. Postoperative adjuvant TACE significantly prolonged the survival in high risk patients with residual tumor (P = 0.0029). Cox model revealed that the benefit of adjuvant TACE was significantly increased by the high risk factors in HCC patients with residual tumor.

CONCLUSIONThe beneficial effect of postoperative TACE was only observed in high risk patients with residual tumor but not in the low risk patients with residual tumor.
