Objective To explore the effect of different resistance amount on the reliability of the lumbar muscles' coordination test.Methods 30 young male adults participated the lumbar muscles' coordination test twice within 1 week by the same tester. In each test, the subjects took 5 kg, 10 kg and 15 kg of resistance randomly. The index included mean of concentric motion, deviation of concentric motion, mean of eccentric motion and deviation of eccentric motion. Intra-class correlation coefficient (ICC) for these 4 test results were applied to evaluate the reliability of those tests. Results The ICCs of the 4 test results were 0.303, 0.500, 0.358 and 0.360 respectively in the 5 kg of resistance group, 0.449, 0.382, 0.365 and 0.272 respectively in the 10 kg of resistance group, and 0.453, 0.442, 0.614 and 0.411 respectively in the 15 kg of resistance group. Conclusion The test-retest reliability can be satisfied in the lumbar muscles' coordination test with 15 kg of resistance.

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 summarize experience of nursing for thoracic breathing reconstruction in patients after cervical spinal cord in-jury (CSCI). Methods 6 cases accepting thoracic breathing reconstruction in our hospital from March 2013 to June 2014 were reviewed from 1 week before operation to 4 weeks after operation. Results All the patients, aged (41.7 ± 16.2) years, received tracheotomy (6.0 ± 5.8) days after injury because of weakened cough, retention of respiratory secretions and dyspnea;the ventilator was used for (45.3±25.9) days, and they received thoracic breathing reconstruction surgery (84±26.7) days after injury. Their vital capacity was (1085±92) ml before opera-tion and was (1680±283) ml 2 weeks after operation with 55%increment (P<0.01). Only 1 patient underwent a delayed wound healing. No pulmonary infection, urinary tract infections and pressure sore occurred until 4 weeks after operation. Conclusion Enhancement of airway care and prevention of pressure sore are the keys to reduce postoperative complications of thoracic breathing reconstruction.

Objective To evaluate the role of hippocampal mammalian target of rapamycin (mTOR) signaling pathway in inflammatory pain in rats.Methods Sixty adult male Sprague-Dawley rats,weighing 180-240 g,were randomly divided into 4 groups (n=6 each) by using a random number table:control group (group C),inflammatory pain group (group IP),dimethyl sulfoxide (DMSO) group and rapamycin (inhibitor of mTOR) group (group R).Inflammatory pain was produced by injection of honey bee venom 50 μl into the plantar surface of the left hindpaw.While the equal volume of normal saline was given instead in group C.In group D,2％ DMSO was injected through a gastric tube into stomach 1 ml per day lasting for 3 days,and inflammatory pain was produced at 1 h after the last injection on 3rd day.In group R,rapamycin 10 mg/kg (in 2％ DMSO) was injected through a gastric tube into stomach 1 ml per day lasting for 3 days,and inflammatory pain was produced at 1 h after the last injection on 3rd day.At 2 h after the model was established,the mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured.Rats were sacrificed after measurement of pain threshold,and hippocampal tissues were obtained for detection of the expression of mTOR,phosphorylated mTOR (p-mTOR),ribosomal S6 kinase (S6K) and phosphorylated S6K (p-S6K).Results Compared to group C,the MWT was significantly decreased,TWL was shortened,the expression of p-mTOR and p-S6K was up-regulated,and no significant change was found in the expression of mTOR and S6K in IP and DMSO groups,and no significant change was found in group R in the MWT,TWL and expression of p-mTOR,mTOR,p-S6K and S6K.Compared to group IP,no significant change was found in group DMSO in the MWT,TWL and expression of p-mTOR,mTOR,p-S6K and S6K,and the MWT was significantly increased,TWL was prolonged,the expression of p-mTOR and p-S6K was down-regulated,and no significant change was found in the expression of mTOR and S6K in group R.Conclusion Hippocampal mTOR signaling pathways are involved in the development of inflammatory pain in rats.
