Objective:
To investigate the trends in incidence of stroke in Jindong District, Jinhua City, Zhejiang Province from 2016 to 2022, so as to provide to the evidence for improving the stroke control strategy.
Methods:
The incidence of stroke in Jindong District from 2016 to 2022 was collected through the Zhejiang Chronic Disease Monitoring Information System, and standardized by the data of the Chinese National Population Census in 2010. The gender-, age- and subtype-specific incidence of stroke was calculated, and the trends in stroke incidence were investigated with average annual percent change (AAPC).
Results:
A total of 9 159 stroke cases were reported in Jindong District from 2016 to 2022, with crude incidence of 386.52/105 and standardized incidence of 276.75/105. The crude incidence of stroke appeared a tendency towards a rise (AAPC=3.704%, 95%CI: 0.792%-6.700%, P<0.05), while the standardized incidence showed no significant changing patterns (P>0.05). The crude incidence of stroke was significantly higher among men than among women (438.69/105 vs. 334.66/105; χ2=14.028, P<0.05), and the standardized incidence of stroke was significantly higher among men than among women (316.58/105 vs. 237.31/105; χ2=6.985, P<0.05). The crude incidence of stroke appeared a tendency towards a rise with age(χ2=5 290.180, P<0.05), and the crude incidence of stroke appeared a tendency towards a decline with age among residents at ages of 45 to 64 years (AAPC=-9.135%, 95%CI: -15.003% to -2.861%, P<0.05), while no significant changing patterns were found in the crude incidence of stroke among residents at other age groups (P>0.05). The crude incidence of ischemic stroke was significantly higher than that of hemorrhagic stroke (306.08/105 vs. 76.89/105; χ2=137.184, P<0.05).
Conclusions
The incidence of stroke appeared a tendency towards a rise in Jindong District from 2016 to 2022, with ischemic stroke as the predominant subtype. Male and middle-aged and elderly populations should be given a high priority for stroke control.

OBJECTIVE:To evaluate the effects of different doses of flurbiprofen axetil on analgesia effects of patients after laparoscopic cholecystectomy. METHODS:120 patients undergoing laparoscopic cholecystectomy were selected and randomly divid-ed into group A,B and C,with 40 cases in each group. Group A,B and C were given the mixture 100 ml of flurbiprofen axetil 100,150 and 200 mg combined with tramadol 600 mg and ondansetron 4 mg respectively and 0.9% Sodium chloride injection for patient controlled intravenous analgesia(PCIA)at the end of operation. Mean arterial pressure(MAP),heart rate(HR)and static and dynamic visual analogue scale(VAS)scores were observed in 3 groups at the end of operation,4,8,24 and 36 h after sur-gery. The incidence of incision pain,neck-shoulder pain and hypochondrium,the occurrence of ADR were recorded 36 h after oper-ation. RESULTS:After operation,There was no statistical significance in comparison of 3 groups with MAP,HR,static and dynam-ic VAS(P>0.05),4,8,24,and 36 h after operation,MAP,HR,static and dynamic VAS score of group B and C decreased sig-nificantly,there was statistical significance,compared with group A(P<0.05);there was no statistical significance in above indi-cators between group B and group C(P>0.05). After operation,the incidence of incision pain,neck-shoulder pain and hypochon-drium in group A were significantly higher than group B and C,with statistical significance(P<0.05),but there was no statistical significance between group B and group C(P>0.05). After operation,the incidence of ADR in group A and B were significantly lower than in group C,with statistical significance(P<0.05),but there was no statistical significance between group A and group B(P>0.05). CONCLUSIONS:Flurbiprofen axetil 150 mg combined with tramadol 600 mg and ondansetron 4 mg can improve he-modynamics and patient controlled intravenous analgesia in patients underwent laparoscopic cholecystectomy with lower incidence of ADR.

Objective To explore the diagnostic value of whole?body bone scan combined with SPECT/CT imaging for osteofibrous dysplasia( OFD) . Methods A total of 30 patients ( 14 males, 16 fe?males, age range 10-48 ( average age 29.2) years) with OFD confirmed by pathology from June 2007 to De?cember 2014 were included. The images of whole?body bone scan and SPECT/CT imaging were retrospec?tively analyzed. Results Nineteen patients (63.3%, 19/30) showed monostotic OFD, which mainly in?volved extremities (n=18), especially the femur. Eleven patients(36.7%, 11/30) showed polyostotic OFD, which frequently be seen unilaterally (n=7). Highly or obviously abnormal uptakes of radiotracer were shown in most lesions (95.3%, 81/85) on whole?body bone planar images, the ribs and extremities showed abnormal uptake along the backbone orientation, while the cranium, pelvis and spine showed irregu?lar bulky uptake of radioactivity. On SPECT/CT images, the lesions of high or obvious abnormal uptake of radiotracer mainly showed cystic expansion growth, ground glass, vegetable sponge and mixed appearance;and the higher the radioactive aggregation degree was, the more the morphological changes were. The density and morphological changes on CT were not obvious for lesions with moderately and mildly abnormal uptake of radiotracer. Conclusion The whole?body bone scan combined with SPECT/CT imaging is an effective diag?nostic method for OFD.
