Objective : To understand the epidemiological characteristics of notifiable respiratory infectious diseases in Huzhou City, Zhejiang Province from 2017 to 2022, so as to provide insights into formulation of respiratory infectious disease prevention and control strategies. Methods: The data pertaining to notifiable respiratory infectious disease in Huzhou City from 2017 to 2022 were collected through the Infectious Disease Report Information System of Chinese Disease Prevention and Control Information System. Epidemiological characteristics of notifiable respiratory infectious disease was analyzed using a descriptive epidemiological method. : Results Conclusions: A total of 31 314 cases of notifiable respiratory infectious diseases were reported in Huzhou City from 2017 to 2022, with an average annual reported incidence of 169.12/105. The reported incidence of notifiable respiratory infectious diseases appeared a tendency towards a rise in Huzhou City from 2017 to 2022 (P<0.05). The top six reported diseases in terms of case numbers were influenza (20 048 cases), tuberculosis (6 920 cases), COVID-19 (1 893 cases), mumps (1 413 cases), pertussis (475 cases) and scarlet fever (442 cases), accounting for 99.61% of the total cases. The incidence of influenza, COVID-19 and pertussis showed a tendency towards a rise, the incidence of mumps and tuberculosis showed a tendency towards a decline (all P<0.05), and scarlet fever remained at a low-level incidence (P>0.05). Respiratory infectious diseases were mainly reported in winter (January, February and December), with 14 644 cases accounting for 46.77%. There were 15 068 cases reported in schools and kindergartens, accounting for 48.12%. The incidence showed a U-shaped variation with age, with the highest incidence in residents at ages of 10 years and below (987.68/105), and showing a tendency towards a rise in residents at ages of 60 years and above. The incidence of respiratory infectious diseases in Huzhou City from 2017 to 2022 increased significantly. Influenza, tuberculosis, COVID-19, mumps and pertussis are key notifiable respiratory infectious diseases. Residents at ages of 10 years and below and 60 years and above should be given a high priority for respiratory infectious disease 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.

Objective To observe the changes of quadriceps tendon in type 2 diabetes mellitus(T2DM)patients based on ultrasonic elastography.Methods Data of 80 T2DM patients(T2DM group)and 80 healthy subjects(control group)were retrospectively analyzed.The general information and ultrasound elastography parameters,including strain ratio(SR)of the ratio of the proximal,middle and distal segments of quadriceps tendon and ipsilateral anterior femoral fat pad were compared between groups,while the correlations of the above SR with the disease course of T2DM and glycosylated hemoglobin(HbA1c)were explored.Results Fasting blood glucose and HbA1c in T2DM group were both significantly higher than those in control group(both P＜0.05).Compared with control group,SR of the proximal,middle and distal segments of quadriceps tendon in T2DM group were all significantly higher(all P＜0.05),especially the distal and proximal segments(t=6.01,5.92).In T2DM group,SR of the proximal,middle and distal segments of quadriceps tendon were positively correlated with the disease course of T2DM(r=0.45,0.20,0.43,all P＜0.05)and HbA1c(r=0.44,0.40,0.33,all P＜0.05).Conclusion SR of quadriceps tendon in T2DM patients significantly increased and positively correlated with the course of disease and HbA1c.

OBJECTIVE To explore the intestinal absorption characteristics of saikosaponins. METHODS Based on everted intestinal sac model， using accumulative absorption amount （Q） and absorption rate constant （Ka） as indexes， UHPLC-MS/MS technique as a method， the absorption of saikosaponin A， B2， C， D and F from total saponins of Bupleurum chinense （8 g/mL， by crude drug） in the duodenum， jejunum and ileum was detected. RESULTS The correlation coefficients （r） of the regression equations for the absorption of saikosaponins A， B2， C and F in the duodenum， jejunum and ileum were all higher than 0.95， while the r of saikosaponin D in the above intestinal segments was lower than 0.95； compared with the absorption of the same composition in the duodenum， the Q and Ka of saikosaponin A and C circulating in jejunum and ileum for 120 min， as well as the Q and Ka of saikosaponin F circulating in the ileum for 120 min were significantly decreased （P＜0.05）. CONCLUSIONS Saikosaponin A and the other 4 saikosaponins are all absorbed in the duodenum， jejunum and ileum； among them， saikosaponin A， B2， C and F are linearly absorbed， which conforms to the zero-order absorption characteristics， but saikosaponin D shows non- linear absorption.

Objective To investigate the resistance level of adult Aedes albopictus to commonly used insecticides in urban areas of Huzhou City， and analyze the trend of insecticide resistance. Methods Aedes albopictus larvae were collected from different urban areas of Huzhou City in 2019 and 2020. The larvae were reared to adults for determining resistance using the WHO standard test kits by contact tube method. Results The mortality was 97.06%‒100.00% in adult Aedes albopictus mosquitoes exposed to 0.4% beta-cypermethrin， 0.1% deltamethrin， 0.5% malathion， 0.05% propoxur and 3% permethrin in 2019. While the adult mosquitoes exposed to 0.4% beta Cypermethrin， 0.08% beta Cypermethrin， 0.03% deltamethrin， 0.4% permethrin， 0.5% malathion and 0.02% propoxur in 2020， the adjusted mortality were 98.58%， 89.09%， 85.64%， 91.34%， 91.43% and 100% respectively . When the insecticide doses on medicated paper were high， the Huzhou populations of Aedes albopictus were sensitive to beta-cypermethrin， deltamethrin， malathion and propoxur， and showed suspected resistance to permethrin. While the Aedes albopictus were exposed to low testing dose， they showed suspected resistance to beta-cypermethrin， deltamethrin， permethrin and malathion， but remained to be sensitive to propoxur. Conclusion The adult Aedes albopictus in Huzhou City from 2019 to 2020 was still sensitive to propoxur， but their resistance to malathion changes from sensitive to resistant. When the contact tube method is used for insecticide resistance， it is suggested that the accurate diagnostic dose should be obtained first before conducting further insecticide resistance tests.

Objective:To summarize our experience in 13 cases of intestinal autotransplantation (IATx) after resection of lesions involving the roots of mesenteric vessels.Methods:The clinical data of 13 patients undergoing IATx in Xijing hospital were retrospectively analyzed. The etiology, surgical procedure and complications were analyzed. The patients were followed up by telephone and regular evaluations.Results:All 13 cases of IATx were successfully completed. For 12 patients who were diagnosed with tumors involving the mesenteric roots, the tumors were removed for cure intent avoiding massive intestinal resection. Pancreaticoduodenectomy was carried out simultaneously in 11 cases. The postoperative complication rate was 85% (11/13). The autograft was resected in 1 patient on the 1st postoperative day due to necrosis from mesenteric thrombosis, leading to short bowel syndrome. One-year survival was 69% (9/13). Among 4 deaths, 1 patient died of liver metastasis, and another died of liver and lung metastases. Five patients were alive 2 years postoperatively.Conclusion:IATx while-technically challenging, avoiding short small bowel syndrome in properly selected patients after resection of lesions especially benign ones involving the roots of mesenteric vessels that were traditionally considered to be "unresectable".

Anaplastic lymphoma kinase (ALK) fusion gene, as a tumor driver gene, was crucial for the occurrence and development of non-small cell lung cancer (NSCLC). Recently, targeted ALK fusion gene has become the main treatment method for ALK-positive NSCLC. The first and second generation ALK inhibitors (ALKi), such as crizotinib, ceritinib, alectinib and ensartinib have been approved in China. However, there was no guidance for the management of ALKi adverse reactions. Therefore, this "Recommendations from experts in the management of adverse reactions to ALK inhibitors (2021 version)" has been summarized, led by Lung Cancer Professional Committee of Sichuan Cancer Society and Sichuan Medical Quality Control Center for Tumor Diseases, to provide practical and feasible strategies for clinical ALKi management specification of adverse reactions.
