Objective:
To investigate the trends in mortality and life loss due to falls among the elderly in Wenzhou City, Zhejiang Province, so as to provide the basis for formulating prevention and control measures for falls among the elderly.
Methods:
The data on fall-related deaths among the elderly aged 60 and above in Wenzhou City were collected through the Wenzhou Chronic Disease Monitoring and Management Information System from 2015 to 2023. The crude mortality was calculated and standardized using the data from the Sixth National Population Census in 2010. The life loss were measured using potential years of life lost (PYLL), average years of life lost (AYLL), and potential years of life lost rate (PYLLR). The trends in mortality and life loss among the elderly were analyzed using the annual percent change (APC) and average annual percent change (AAPC).
Results:
There were 11 378 deaths due to falls among the elderly in Wenzhou City from 2015 to 2023, with a crude mortality of 82.67/100 000 and a standardized mortality of 65.32/105, which appeared no significant changing trend (AAPC=3.401%、2.995%,both P>0.05). There was a tendency towards a rise from 2019 to 2023 (APC=12.592%、11.507%, both P<0.05). The majority of falls occurred at home, with 6 312 cases accounting for 55.48%. The primary types of fall-related deaths were slips, trips, and falls on the same level, with 8 541 cases representing 75.07%. The crude mortality and standardized mortality of falls in males were 76.63/105 and 60.86/105, which were lower than that in females at 88.72/100 000 and 70.33/100 000 (both P<0.05), and the trends were consistent with the overall population. The crude mortality of falls among the elderly increased with age (P<0.05). From 2015 to 2023, the crude mortality of falls among the elderly aged 60 to <65 years showed an upward trend (AAPC=4.860%, P<0.05), while no significant trend was observed in other age groups (all P>0.05). The PYLL was 5 123 person-years, the AYLL was 0.45 years per person, and the PYLLR was 0.37‰. From 2015 to 2023, PYLL showed an upward trend (AAPC=5.477%, P<0.05). The PYLL, AYLL, and PYLLR for males were 3.08 times, 3.48 times, and 2.67 times those of females, respectively.
Conclusions
From 2015 to 2023, the mortality of falls among the elderly in Wenzhou City had remained relatively stable. However, PYLL showed an upward trend. Males and older seniors were key groups for falls prevention. It is recommended to enhance health education and promote age-friendly home modifications to prevent falls among the elderly.

Objective To investigate the molecular mechanism of Huangjing Zanyu Capsule(HJZY),a new class-Ⅲ traditional Chinese medicine for the treatment of male infertility developed by Wang Qi,an academician of the Chinese Academy of Engineering,based on AMPK-mediated mitophagy in the treatment of oligoasthenospermia.Methods Acrolein(ACR)was used to treat GC-2spd(ts)mouse spermatocytes to establish a cell model of oligoasthenospermia.The optimal ACR concentration and exposure time for subsequent modeling were determined by CCK8 cell viability assay.After successful modeling,the cells were cultured in complete medium containing different concentrations of HJZY.Then,cell viability was assessed by CCK8 assay after 24 hours,and the subsequent treatment concentration was determined based on the cell viability.After the GC-2spd cells adhered to the wall,they were divided into a normal control(NC)group,a modeling group,and an ACR+HJZY treatment group.The effect of HJZY on mitophagy was observed by confocal fluorescence microscopy.The three groups of cells were transfected with siRNA-NC and siRNA-AMPK,respectively,and divided into six groups,including siRNA-NC+control,siRNA-NC+ACR,siRNA-NC+ACR+HJZY,siRNA-AMPK+control,siRNA-AMPK+ACR,and siRNA-AMPK+ACR+HJZY groups.Western blot was performed to validate the regulatory effect of HJZY on mitophagy-related proteins,such as p-AMPK,LC3B,P62,PINK1,Parkin,TBK1,and ULK1,which were all proteins mediated by AMPK.Results Through the cell viability assay,34 μmol/L was selected as the the modeling concentration of ACR,and 20 minutes was selected as the modeling time The treatment concentration of HJZY was 160 μmol/L.Confocal fluorescence microscopy showed that HJZY had,to a certain degree,a positive regulatory effect on the mitochondrial membrane potential of damaged spermatogenic cells.The mitochondrial membrane potential of the model group decreased significantly compared with that of the NC group.After exposure to treatment,the cell membrane potential of the ACR+HJZY treatment group increased compared with that of the model group,and the difference was statistically significant(P<0.05).Western blot results showed that the expression levels of p-AMPK/AMPK and PINK1 proteins in the siRNA-NC+ACR group were significantly lower than those in the siRNA-NC+control group(P<0.001).The level of Parkin protein in the siRNA-NC+ACR group was lower than that in the siRNA-NC+control group,but the difference was not statistically significant.After the administration of HJZY,the levels of these 3 proteins increased,and those in the siRNA-NC+ACR+HJZY group were higher than those in the siRNA-NC+ACR group(P<0.001).The expression levels of LC3B,P62,TBK1,and ULK1 proteins in the siRNA-NC+ACR group were higher than those in the siRNA-NC+control group(P<0.01),and those in the siRNA-NC+ACR+HJZY group were lower than those in the siRNA-NC+ACR group(P<0.05).After transfection with the gene-silencing siRNA-AMPK,the expression levels of p-AMPK/AMPK,PINK1,and Parkin proteins in the siRNA-AMPK+ACR group were lower than those in the siRNA-AMPK+control group(P<0.01).After the administration of HJZY,there was no significant difference in the levels of these three proteins between the siRNA-AMPK+ACR+HJZY group and the siRNA-AMPK+ACR group.The expression level of LC3B protein in the siRNA-AMPK+ACR+HJZY group was still lower than that in the siRNA-AMPK+ACR group(P<0.01).There was no significant difference in the levels of P62,TBK1,and ULK1 proteins between the siRNA-AMPK+ACR+HJZY group and the siRNA-AMPK+ACR group.Compared with the siRNA-NC+control group,the siRNA-AMPK+control group showed significantly decreased expression levels of p-AMPK/AMPK,ULK1,and TBK1 proteins(P<0.001),decreased expression of PINK1 protein(P<0.05),and increased expression of P62 protein(P<0.001).Compared with the siRNA-NC+ACR group,the siRNA-AMPK+ACR group showed decreased expression of TBK1 protein(P<0.001),decreased expression of LC3B protein(P<0.01),and decreased expression of ULK1 protein(P<0.05).The expression levels of PINK1 and Parkin proteins in the siRNA-AMPK+ACR group were lower than those in the siRNA-NC+ACR group,but the difference was not statistically significant.Compared with the siRNA-NC+ACR+HJZY group,the siRNA-AMPK+ACR+HJZY group showed decreased expression of p-AMPK/AMPK,PINK1,and Parkin proteins(P<0.05),decreased expression of LC3B protein(P<0.01),and increased expression of P62 protein(P<0.001).There was no significant difference in the levels of TBK1 and ULK1 proteins between the siRNA-AMPK+ACR+HJZY group and the siRNA-NC+ACR+HJZY group.Conclusion HJZY may exert its therapeutic effect on oligoasthenospermia by regulating AMPK-mediated mitophagy.

Seventy-three patients with spinal nerve sheath tumor who were surgically treated in our hospital during the years 2004-2010 were retrospectively reviewed with respect to recovery of neurological function, recurrence of the tumor and occurrence of kyphotic deformities. Preoperative clinical manifestations, imaging data, surgical records and follow-up results were comprehensively analyzed. The follow-up duration was 12-60 months with an average of 32.0 months. Out of the 73 cases enrolled, 69 had gradual recovery of sensation, motor and sphincter functions 1 week to 3 months after operation. Forty-six cases had incomplete paralysis, whose American Spinal Injury Association (ASIA) grades, however, were gradually increased during the follow-up period, 4 cases had no significant improvement of the clinical symptoms and no change in ASIA grades during the follow-up period. Two cases had postoperative recurrence of the tumor. There were no deaths, no spinal instability, and no kyphotic malformations found in any cases. Our study indicated that complete removal of the tumor is important for good recovery, and an ideal surgical method may reduce the recurrence of the tumor or the occurrence of complications.

Objective To determine whether sleep-disordered breathing (SDB) may lead to nocturnal myocardial ischemia and whether the severity of this ischemia may be relieved by nasal continuous positive airway pressure (CPAP). Methods Overnight polysomnogram examination and simultaneous 3-channel Holter monitoring were performed on 76 patients with moderate to severe SDB and no history of coronary heart disease. All the cases were treated with CPAP for one night. ST depression was defined as a ST segment decrease of more than 1 mm from baseline and lasting 1 min or more. The total duration (minutes) of ST depression was indexed to the total sleep time (minutes per hour of sleep). Results Twenty-eight patients (37%) showed ST segment depression during their sleep. Before CPAP treatment, the respiratory disturbance index (RDI) and arousal index were significantly higher during periods of ST depression than when ST segments were isoelectric, whereas no significant difference was found in blood oxygen saturation (SaO2). After the CPAP treatment of patients with ST depression, the duration of ST depression was significantly reduced from 36.8±18.9 to 11.4±13.2 min/h (P<0.05). ST depression-related indexes, including RDI, arousal index and the percentage of sleep time spent at SaO2 below 90% (TS90/ TST), were all significantly decreased, with RDI from 63.4±23.8 to 8.1±6.6 /h, arousal index from 51.2±18.9 to 9.6±5.4 /h, and TS90/ TST from 50.6±21.4 to 12.9±14.7% (P<0.05). Conclusion ST-segment depression is rather common in patients with moderate to severe SDB, and CPAP treatment can significantly reduce the duration of ST depression. ST depression in these patients may reflect the myocardial ischemia that really exists and the non-ischemic changes associated with recurrent SDB.
