Objective:To investigate the clinical efficacy and safety of intravenous thrombolysis with different doses of alteplase in the treatment of acute cerebral infarction in older adult patients.Methods:A total of 65 older adult patients with acute cerebral infarction (onset within 4.5 hours, age ≥ 75 years) who underwent intravenous thrombolysis in Wenzhou Central Hospital from February 2021 to February 2022 were included in this study. They were randomly assigned to undergo intravenous thrombolysis with either low dose alteplase (0.6 mg/kg, low dose group, n = 32) or standard dose alteplase (0.9 mg/kg, standard dose group, n = 33). The National Institutes of Health Neurological Stroke Scale score before and 24 and 48 hours after treatment, modified Rankin scale score before and 7, 14 and 90 days after treatment, serum C-reactive protein (CRP), neuron-specific enolase (NSE) and tumor necrosis factor-α (TNF-α) levels before and 24 hours after treatment, 24-hour incidence of intracranial hemorrhage, 24-hour incidence of symptomatic intracranial hemorrhage, and 90-day mortality were compared between the two groups. Results:Compared with before treatment, the National Institutes of Health Neurological Stroke Scale scores in each group were significantly decreased at 24 and 48 hours after treatment (low dose group, t24 h = 6.78, t48 h = 7.86; standard dose group: t24 h = 8.09, t48 h = 10.13, all P < 0.001). Compared with before treatment, the modified Rankin scale score in each group was significantly decreased at 7, 14 and 90 days after treatment (low-dose group: t7 d = 5.19, t14 d = 8.47, t90 d = 9.85; standard dose group: t7 d = 6.83, t14 d = 7.74, t90 d = 13.66, all P < 0.001). At 24 hours after treatment, serum levels of CRP, NSE, TNF-α in each group were significantly decreased (low-dose group: tCRP = 5.13 , tNSE = 4.22, tTNF-α = 34.29; standard dose group: tCRP = 4.87, tNSE = 5.53, tTNF-α = 31.98, all P < 0.001). At each time point after treatment, there were no significant differences in these indices between the two groups (all P > 0.05). The 24-hour incidence of intracranial hemorrhage in the low dose group was significantly lower than that in the standard dose group ( χ2 = 4.58, P = 0.032). There were no significant differences in incidence of symptomatic intracranial hemorrhage and 90-day mortality between the two groups (all P > 0.05). Conclusion:Intravenous thrombolysis with low dose alteplase (0.6 mg/kg) for the treatment of acute cerebral infarction in older adult patients exhibits equivalent clinical efficacy to that with standard dose alteplase (0.9 mg/kg), and the former is much safer than the latter.

Objective To investigate the epidemiological information of patients in pre-hospital medical care for our large and medium-sized cities and probe the patients' characteristic. Method The data in 2008 were exported from the computer databases of 8 large and medium-sized cities' emergency medical centers in our country.The thorough records of data were conducted to statistical analysis. Results ( 1 ) The scheduling time, running time, rescue time, returning time, total time and service radius in the pre-hospital medical care group were 2.16± 1.10(min), 14.01 ±6.82(min), 12.12±5.96(min), 14.08± 6.85(min), 42.34± 20.21(min)and 8.50±4.18(km), and the above parameter in the non-death group were 2.19 ± 1.13(min), 14.15 ± 7.14(min),11.60±6.72(min), 14.92 ±6.89(min), 41.86± 19.53(minutes) and 8.63±4.31(Km), and the above parameter in the death group were 2.10± 1.08(min), 13.68 ± 7.14(min), 25.25 ± 12.34(min), 13.75±6.48(min), 54.74 ± 25.47(min) and 7.86± 3.91(Km), and the above parameter in the non-sudden cardiac death group were2.09± 1.03(min), 13.58±6.78(min), 25.53± 12.34(min), 13.60± 6.54(min), 53.79±23.77(min) and 7.67 ± 3.86(Km), and the above parameter in the sudden cardiac death group were 2.12 ±1.02(min), 14.10±7.05(min), 24.79± 12.08(min), 13.79±6.61(min), 54. 80 ± 25. 36( min) and 7.90±3.92(Km) respectively. The scheduling time, running time, returning time and service radius in the death group were less than those of the non-death group, but the rescue time and total time of the former were more than those of the latter respectively ( P < 0.05 or P < 0. 001 ). The scheduling time and returning time didn' t have significant difference between the sudden cardiac death group and the non-sudden cardiac death group respectively ( P > 0.05), but the running time, total time and service radius of the sudden cardiac death group were more than those of the non-sudden cardiac death group, and the rescue time of the former was less than that of the latter respectively ( P < 0.05 or P < 0.001 ). (2)The patients' amount in pre-hospital medical care group, the non-death group, the death group, the non-sudden cardiac death group and the sudden cardiac death group were at most in first quarter, and the least time slice of patients' amount were 4:00~ 6:00, 4:00~6:00, 4:00~ 6:00, 22:00~ 24:00, 2:00~4:00 respectively, and the most time slice of patients' amount were 20:00~ 22:00, 20:00~22:00, 8:00~ 10:00, 2:00 ~ 4:00, 8:00 ~ 10:00 respectively. (3)In 241 876 cases of pre-hospital medical care group, the patients' amount of trauma was at most, whose age grades was by far among21 ~50, and the others in sequence were nervous system, circulatory system, other group, digestive system, respiratory system and poisoning group respectively, whose age grades in nervous system, circulatory system and respiratory system was by far above 51, especially above 70. The patients' age grades in other group and digestive system had two climax age groups, which the one was 21 ~ 30, and the other was above 70. The patients' age grades in poisoning group was by far among 21 ~ 50, which the patients' amount of acute alcoholism was at the most. (4) In 12 568 cases of death group, the death amount of circulatory system, other group, respiratory system, nervous system and digestive system ranked at the lst,2nd,4th,5th 8th respectively, whose age grades was by far above 51, especially above 70,and the patients' amount of sudden cardiac death was at the most in the death amount of circulatory system. The death amount of trauma and poisoning group ranked at the 3rd, 6th respectively, whose age grades was by far among 21 ~ 50. (5)The total amount, the death amount and the sudden cardiac death amount of male patients were more than those of female patients. (6)The percentage of the death group to the pre-hospital medical care group was 5.20%, and the percentage of the sudden cardiac death group to the pre-hospital medical care group was 1.29%,and the percentage of the sudden cardiac death group to the death group was 24.87 %, and the percentage of the sudden cardiac death group to the circulatory system group was 67.33 %. Conclusions ( 1 )The trauma and the sudden cardiac death are the overriding reason of disease and the overriding reason of death in our large and medium-sized cities respectively. (2) It is very important to cut the death rate of the middle-old age patients by strengthening prevention and cure of cardiovascular and cerebrovascular diseases, discerning the critical illness early and improving the level of pre-hospital medical care. (3)It is a strong method to decrease the total amount and the death amount of the trauma, especially in traffic accident, by strengthening safety in production, observing traffic regulation and enhancing the legal awareness.

Objective To investigate the effect of sarcopenia on balance function in patients with Parkinson's disease(PD).Methods Sixty patients with PD diagnosed by our hospital from January 2021 to June 2021 were selected as the study objects.All patients were divided into myopenia group and control group according to the diagnostic criteria established by the Asian Working Group for Sarcopenia(AWGS)in 2014.The UPDRS Ⅲ,Berg balance scale,timed-up-go test and activity balance confidence scale were compared between the two groups.Results The grip strength,walking speed and RASM of the myopenia group were lower than those of the control group(P<0.05);Compared with the control group,the number of falls,UPDRS Ⅲ,Berg score and TUG duration in the myopenia group were significantly increased(P<0.05).The total score of ABC,ABC-2,ABC-3,ABC-5,ABC-6,ABC-7,ABC-8,ABC-9,ABC-11,ABC-14,ABC-15,ABC-16 in myopenia group were poor,and the differences were statistically significant(P<0.05).Further analyzing the differences between sex genders,we found that female sarcopenia had lower scores on ABC-2,ABC-3,ABC-8,ABC-9,ABC-11,ABC-13,ABC-14,ABC-15,ABC-16,and total score indexes,with statistically significant differences.Conclusion Myopenia significantly affects the balance function of PD and increases the risk of falls.
