With the recent success of the Bruton's tyrosine kinase (BTK) inhibitor, ibrutinib, and the phosphoinositide-3-kinase (PI3K) inhibitor idelalisib in the treatment of patients with relapsed or refractory chronic lymphocytic leukemia (CLL), a number of new agents targeting the B cell receptor (BCR) pathway are in clinical development. In the 57th American Society of Hematology (ASH) annual meeting, great interests are still focused on these two drugs, either monotherapy or combination in the treatment of CLL. On the other hand, SYK inhibitors, new BTK and PI3K antagonists are also coming to the forefront, casting a new light on the treatment of ibrutinib/idelalisb-resistant patients. The progresses of BCR pathway inhibitors in CLL will be summarized in this paper based on the reports in the 57th ASH annual meeting.

Objective To investigate the influence of different interventional treatment timing on the prognosis of patients with intracranial aneurysms. Methods One hundred and thirty-eight patients with ruptured intracranial aneurysms were divided into group A (Ⅰ- Ⅲ grade) with 109 cases and group B ( Ⅳ- Ⅴ grade) with 29 cases according to Hunt-Hess grade when admitted. All patients received interventional treatment, the operation period was divided into early, middle and late stage according to the different time from disease time to operation, then compared the good rate, cerebral vasospasm and hydrocephalus incidence of patients underwent surgery at different period. Results The good rate at different period in group A were respectively 69.7% (23/33),58.8% (10/17) and 61.0% (36/59),which and the cerebral vasospasm and hydrocephalus incidence of patients underwent surgery at different period in group A had no significant difference(P > 0.05). The good rate of patients received surgical treatment at early stage in group B was 46.2%(6/13), which was significantly superior to late stage (0), the difference was statistically significant (P < 0.05), while the cerebral vasospasm and hydrocephalus incidence of patients underwent surgery at different period in group B had no significant difference(P> 0.05). Conclusion The prognosis of patients with Hunt-Hess grade Ⅰ - Ⅲ grade undergoing interventional treatment at early, middle and late stage can be satisfactory, while grade Ⅳ - Ⅴ grade patients should receive interventional treatment at early stage.

Objective: To investigate the trends in incidence and epidemiological characteristics of notifiable infectious diseases in Huzhou City, Zhejiang Province from 2005 to 2023, so as to provide insights into optimizing infectious disease surveillance and control. Methods: Data of notifiable infectious disease cases in Huzhou City from 2005 to 2023 were collected from the Infectious Disease Report Information System of Chinese Disease Prevention and Control Information System. Trends in incidence were analyzed using annual percent change (APC) and average annual percent change (AAPC). The population distribution and seasonal characteristics were descriptively analyzed. Results: From 2005 to 2023, a total of 504 283 cases of notifiable infectious diseases were reported in Huzhou City, with an annual crude incidence rate of 892.65/105 and a standardized incidence rate of 989.21/105. The incidence rate of notifiable infectious diseases in Huzhou City showed an upward trend (AAPC=8.886%, P<0.05), of which there was an obvious upward trend from 2021 to 2023 (APC=95.996%, P<0.05). After the removal of COVID-19 incidence, the incidence trend was basically unchanged (AAPC=7.970%, P<0.05). From 2005 to 2023, the incidence rate of class A and B notifiable infectious diseases showed no obvious trend (P>0.05), and the incidence rate of class A and B respiratory infectious diseases showed an upward trend (AAPC=6.958%, P<0.05). After the removal of COVID-19 incidence, the two showed a downward trend (AAPC=-7.680% and -8.660%, both P<0.05). The incidence rate of class A and class B intestinal infectious diseases, blood-borne and sexually transmitted infectious diseases showed a downward trend (AAPC=-14.849% and -5.977%, both P<0.05), while the incidence rates of natural and insect-borne infectious diseases did not show a significant trend (P>0.05). The overall incidence rate of class C infectious diseases showed an upward trend (AAPC=13.058%, P<0.05). The incidence rate ratio (IRR) of notifiable infectious diseases between males and females was 1.26 (95%CI: 1.25-1.27). A total of 204 043 cases under 10 years were reported, accounting for 40.46%. The peak incidence of class A and B respiratory infectious diseases was in January, May and June, while that of class A and B intestinal infectious diseases was from June to October. The peak incidence of class C respiratory infectious diseases was in January, March, April and December, while that of class C intestinal infectious diseases was from May to August and from November to December. Conclusions The incidence rate of notifiable infectious diseases in Huzhou City showed an upward trend from 2005 to 2023, which was more obvious from 2021 to 2023. Men and children under 10 years were the high-risk population. The incidence of respiratory and intestinal infectious diseases had obvious seasonal characteristics.
