Objectives:To investigate the relationship between locations of ventricular septal perforation and 30-day prognosis in patients with acute myocardial infarction complicated by ventricular septal perforation.Methods:Clinical data of 150 acute myocardial infarction patients with ventricular septal perforation admitted to Fuwai Hospital of Chinese Academy of Medical Sciences and People's Hospital of Xinjiang Uygur Autonomous Region from January 2009 to October 2023 were retrospectively analyzed.Kaplan-Meier method was used to compare the difference in 30-day survival rate among patients with different sites of ventricular septal perforation.The impact of locations of ventricular septal perforation on 30-day prognosis of acute myocardial infarction patients was evaluated by multivariate Cox regression analysis(forward stepwise).Results:In acute myocardial infarction patients,the occurrence of anterior ventricular septal perforation was higher than that of posterior ventricular septal perforation(79.5%vs.20.5%,P<0.001).In the anterior ventricular septal perforation patients,females were more common(50.0%vs.22.6%,P=0.006),the blood glucose level was higher([10.51±5.99]mmol/L vs.[8.02±2.81]mmol/L,P=0.026),the left ventricular end-diastolic diameter was smaller([50.7±6.1]mm vs.[55.1±5.0]mm,P<0.001),the ventricular septal aperture was also smaller([9.8±4.6]mm vs.[12.6±5.4]mm,P=0.004),30-day mortality was higher(55.8%vs.35.5%,P=0.043)compared with posterior ventricular septal perforation patients.Multivariate Cox regression analysis(forward stepwise)showed that no transthoracic surgery or transcatheter closure(HR=26.344,95%CI:8.261-84.009,P<0.001)and anterior ventricular septal perforation(HR=2.432,95%CI:1.281-4.619,P=0.007)were associated with increased risk of 30-day all-cause mortality in patients with acute myocardial infarction complicated by ventricular septal perforation.Conclusions:In patients with acute myocardial infarction complicated by ventricular septal perforation,the incidence of anterior ventricular septal perforation is higher than posterior ventricular septal perforation and the 30-day all-cause mortality of anterior ventricular septal perforation patients is also higher.No transthoracic surgery or transcatheter closure and anterior ventricular septal perforation are the independent influential factors of 30-day all-cause mortality in patients with acute myocardial infarction and ventricular septal perforation.

Objective:To investigate the protective effects of resveratrol (RSV) on human sperm cryopreservation and explore its underlying protective mechanisms.Methods:A total of 165 normal fresh semen samples were collected from the Reproductive Medicine Center, Department of Obstetrics and Gynecology and Human Sperm Bank of the First Affiliated Hospital of Anhui Medical University between December 2022 and December 2024. Among them, 65 samples were used to obtain semen parameters before and after conventional freezing. Each sample of the other 104 samples was mixed at a 2∶1 volume ratio with cryoprotectant containing 0, 10 -?, 10 -?, or 10 -? mol/L RSV, followed by cryopreservation in liquid nitrogen for 24 h. Post-thaw assessments included routine sperm parameters, sperm DNA fragmentation index (DFI) evaluated by sperm chromatin dispersion assay, reactive oxygen species (ROS) levels measured via flow cytometry, RSV and nuclear factor erythroid 2-related factor 2 (NRF2) interactions examined by molecular docking and cellular thermal shift assay (CETSA), NRF2 protein contents analyzed by immunofluorescence and Western blotting, mRNA levels of NRF2 and downstream antioxidant proteins Heme Oxygenase-1 (HO-1) and NAD(P)H: quinone oxidoreductase 1 (NQO1) quantified by qRT-PCR and effects of NRF2 inhibitor ML385 on sperm parameters. Results:Compared with fresh samples, conventional cryopreservation significantly reduced sperm motility (all P<0.001). The addition of 10 -? mol/L RSV significantly improved the percentage of forward motile sperm after freezing (26.98%±8.98% vs. 19.61%±8.03%, P<0.001) while reducing DFI (9.84%±3.81% vs. 15.06%±4.22%, P<0.001) and ROS levels ( P<0.001) compared with the post-freezing group without the addition of RSV. Both molecular docking analysis and CETSA confirmed that RSV interacted with NRF2. Notably, sperm cryopreserved with 10 -? mol/L RSV exhibited significantly higher contents of NRF2 and its downstream effectors HO-1 and NQO1 compared with the post-freezing group without the addition of RSV (all P<0.001). This protective effect was markedly attenuated by co-treatment with the NRF2 inhibitor ML385, as evidenced by a significant decline in sperm motility ( P<0.001). Conclusion:RSV exerts cryoprotective effects likely through NRF2-mediated antioxidant pathways, reducing oxidative stress and enhancing post-thaw sperm quality.

Objective:To describe the trend of changes in the disease burden of age-related hearing loss in China and globally from 1990 to 2021,to forecast the prevalence and years lived with disability(YLD)rates of age-related hearing loss from 2022 to 2036,and to provide a reference for the prevention and control of the disease burden associated with age-related hearing loss.Methods:Using the Global Burden of Disease 2021(GBD2021)data,this study selected age-standardized prevalence rate(ASPR)and YLD as indicators.The disease burden and long-term trends of age-related hearing loss in China and globally from 1990 to 2021 were described by different socio-demographic index(SDI)and gender.Joinpoint regression was used to calculate the average annual percent change(AAPC)to assess the trend changes in the disease burden.Decomposition analysis was applied to explore the relative im-pacts of aging,population growth,and epidemiological changes on the variation in disease burden.An autoregressive integrated moving average(ARIMA)model was used to forecast the age-standardized pre-valence rate and YLD rates from 2022 to 2036.Results:The prevalence of age-related hearing loss in China in 2021 was 82 162.49(73 288.08-89 187.21)per 100 000,higher than the global SDI level of 66 238.16(59 982.54-72 669.82)per 100 000,the high SDI region's level of 57 650.42(52 059.12-63 889.02)per 100 000,the upper-middle SDI region's level of 69 115.59(62 494.18-75 340.64)per 100 000,the middle SDI region's level of 72 365.56(65 181.43-78 912.01)per 100 000,the lower-middle SDI region's level of 64 439.66(58 368.22-71 468.27)per 100 000,and the low SDI region's level of 61 725.25(55 749.18-68 477.67)per 100 000.The age-related hearing loss YLD rate in China was 2 762.98[95％uncertainty interval(UI):1 855.28-3 880.68]per100000,higher than the global SDI level of 2 236.75(95％UI:1 511.56-3 155.88)per 100 000,the high SDI region's level of 1 805.79(95％UI:1 212.69-2 577.17)per 100 000,the upper-middle SDI re-gion's level of 2 316.58(95％UI:1 557.53-3 274.87)per 100 000,the middle SDI region's level of 2 480.99(95％UI:1 678.17-3 489.24)per 100 000,the lower-middle SDI region's level of 2 313.28(95％UI:1 578.35-3 271.50)per 100 000,and the low SDI region's level of 2 383.55(95％UI:1 623.66-3 365.68)per 100 000.From 1990 to 2021,both the prevalence and YLD rate of age-related hearing loss in China showed an increasing trend,rising by an average of 0.18％(95％CI:0.16％-0.19％)and 0.29％(95％CI:0.27％-0.30％)per year,respectively.The rates of in-crease in prevalence were the same for both men and women,with men showing a 0.18％increase(95％CI:0.17％-0.19％,P＜0.001)and women showing a 0.18％increase(95％CI:0.16％-0.19％,P＜0.001).However,the YLD rate increase was faster in men than in women,with men experiencing a 0.32％increase(95％CI:0.27％-0.37％,P＜0.001)and women experiencing a 0.27％increase(95％CI:0.26％-0.28％,P＜0.001).Decomposition analysis showed that population growth was the main factor driving the increase in prevalence and YLD rate globally and across different SDI regions.However,aging was the primary factor contributing to the increase in prevalence and YLD rate in China.ARIMA model predictions suggested that the prevalence and YLD rate of age-related hearing loss would continue to rise from 2022 to 2036,with the predicted prevalence and YLD rate in 2036 reaching 89 723.99 per 100 000 and 2 872.47 per 100 000,respectively.Conclusion:The prevalence and disease burden of age-related hearing loss in individuals aged 60 and above in China rank first globally.From 1990 to 2021,both the prevalence and YLD rate of age-related hearing loss have shown a continuous upward trend,consistently surpassing the levels observed in various SDI regions worldwide.The prevalence and disease burden of age-related hearing loss are particularly significant among elderly men.Moreover,projections indicate that the disease burden of age-related hearing loss will continue to rise over the next 15 years.Therefore,it is urgent to pay close attention to age-related hearing loss in this specific population,and early intervention measures are crucial to reduce the disease burden associated with age-related hearing loss.

Objective:To study echinococcosis in the population and canine Echinococcus infection in Yushu City, Qinghai Province, and to explore the current epidemic situation and main transmission species of Echinococcus. Methods:In June 2023, a multi-stage sampling method was used to select 2 villages each in Shanglaxiu Township and Longbao Town, Yushu City, Qinghai Province. Each village included at least 100 permanent residents who had lived locally for at least 1 year and were 2 years old or older as the survey subjects. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum antibodies against Echinococcus larvae in the population, and B-mode ultrasound was used for abdominal organ scanning. Meanwhile, on the main roads of Shanglaxiu Township and Longbao Town, canine feces were collected in designated areas at intervals. ELISA was used to detect the antigen of canine fecal Echinococcus, and PCR was used to detect the types of parasites ( Echinococcus multilocularis, Echinococcus granulosus and Echinococcus shiquicus). Results:A total of 511 residents were investigated in Yushu City, and the positive rate of serum Echinococcus larvae antibodies in the population was 26.22% (134/511), and the detection rate of echinococcosis B-mode ultrasound was 1.37% (7/511). Among them, the detection rates of B-mode ultrasound for cystic echinococcosis (CE) and alveolar echinococcosis (AE) were 1.17% (6/511) and 0.20% (1/511), respectively. The positive rate of Echinococcus antigen in 543 canine feces detected by ELISA was 12.89% (70/543). PCR was used to test 497 canine feces, and the detection rate of Echinococcus was 3.02% (15/497). Among them, the detection rate of Echinococcus multilocularis was higher than that of Echinococcus granulosus [2.82% (14/497) vs 0.20% (1/497)], and the difference was statistically significant (χ 2 = 11.44, P < 0.001). No Echinococcus shiquicus was detected. Conclusions:The positive rates of Echinococcus larvae antibodies in the population and canine Echinococcus antigen in Yushu City, Qinghai Province are both relatively high. There is a mixed epidemic of CE and AE, with Echinococcus multilocularis being the main species.

Objectives:To investigate the relationship between locations of ventricular septal perforation and 30-day prognosis in patients with acute myocardial infarction complicated by ventricular septal perforation.Methods:Clinical data of 150 acute myocardial infarction patients with ventricular septal perforation admitted to Fuwai Hospital of Chinese Academy of Medical Sciences and People's Hospital of Xinjiang Uygur Autonomous Region from January 2009 to October 2023 were retrospectively analyzed.Kaplan-Meier method was used to compare the difference in 30-day survival rate among patients with different sites of ventricular septal perforation.The impact of locations of ventricular septal perforation on 30-day prognosis of acute myocardial infarction patients was evaluated by multivariate Cox regression analysis(forward stepwise).Results:In acute myocardial infarction patients,the occurrence of anterior ventricular septal perforation was higher than that of posterior ventricular septal perforation(79.5%vs.20.5%,P<0.001).In the anterior ventricular septal perforation patients,females were more common(50.0%vs.22.6%,P=0.006),the blood glucose level was higher([10.51±5.99]mmol/L vs.[8.02±2.81]mmol/L,P=0.026),the left ventricular end-diastolic diameter was smaller([50.7±6.1]mm vs.[55.1±5.0]mm,P<0.001),the ventricular septal aperture was also smaller([9.8±4.6]mm vs.[12.6±5.4]mm,P=0.004),30-day mortality was higher(55.8%vs.35.5%,P=0.043)compared with posterior ventricular septal perforation patients.Multivariate Cox regression analysis(forward stepwise)showed that no transthoracic surgery or transcatheter closure(HR=26.344,95%CI:8.261-84.009,P<0.001)and anterior ventricular septal perforation(HR=2.432,95%CI:1.281-4.619,P=0.007)were associated with increased risk of 30-day all-cause mortality in patients with acute myocardial infarction complicated by ventricular septal perforation.Conclusions:In patients with acute myocardial infarction complicated by ventricular septal perforation,the incidence of anterior ventricular septal perforation is higher than posterior ventricular septal perforation and the 30-day all-cause mortality of anterior ventricular septal perforation patients is also higher.No transthoracic surgery or transcatheter closure and anterior ventricular septal perforation are the independent influential factors of 30-day all-cause mortality in patients with acute myocardial infarction and ventricular septal perforation.

Objective:To investigate the protective effects of resveratrol (RSV) on human sperm cryopreservation and explore its underlying protective mechanisms.Methods:A total of 165 normal fresh semen samples were collected from the Reproductive Medicine Center, Department of Obstetrics and Gynecology and Human Sperm Bank of the First Affiliated Hospital of Anhui Medical University between December 2022 and December 2024. Among them, 65 samples were used to obtain semen parameters before and after conventional freezing. Each sample of the other 104 samples was mixed at a 2∶1 volume ratio with cryoprotectant containing 0, 10 -?, 10 -?, or 10 -? mol/L RSV, followed by cryopreservation in liquid nitrogen for 24 h. Post-thaw assessments included routine sperm parameters, sperm DNA fragmentation index (DFI) evaluated by sperm chromatin dispersion assay, reactive oxygen species (ROS) levels measured via flow cytometry, RSV and nuclear factor erythroid 2-related factor 2 (NRF2) interactions examined by molecular docking and cellular thermal shift assay (CETSA), NRF2 protein contents analyzed by immunofluorescence and Western blotting, mRNA levels of NRF2 and downstream antioxidant proteins Heme Oxygenase-1 (HO-1) and NAD(P)H: quinone oxidoreductase 1 (NQO1) quantified by qRT-PCR and effects of NRF2 inhibitor ML385 on sperm parameters. Results:Compared with fresh samples, conventional cryopreservation significantly reduced sperm motility (all P<0.001). The addition of 10 -? mol/L RSV significantly improved the percentage of forward motile sperm after freezing (26.98%±8.98% vs. 19.61%±8.03%, P<0.001) while reducing DFI (9.84%±3.81% vs. 15.06%±4.22%, P<0.001) and ROS levels ( P<0.001) compared with the post-freezing group without the addition of RSV. Both molecular docking analysis and CETSA confirmed that RSV interacted with NRF2. Notably, sperm cryopreserved with 10 -? mol/L RSV exhibited significantly higher contents of NRF2 and its downstream effectors HO-1 and NQO1 compared with the post-freezing group without the addition of RSV (all P<0.001). This protective effect was markedly attenuated by co-treatment with the NRF2 inhibitor ML385, as evidenced by a significant decline in sperm motility ( P<0.001). Conclusion:RSV exerts cryoprotective effects likely through NRF2-mediated antioxidant pathways, reducing oxidative stress and enhancing post-thaw sperm quality.

Objective To explore the application effect of the Roy adaptation model in continuing care for patients with acute-ST segment elevation myocardial infarction(STEMI)after interventional treatment.Methods A total of 120 STEMI patients who received emergency percutaneous coronary intervention at Henan Chest Hospital from March 2020 to February 2022 were selected as the research subjects.Patients were randomly divided into the observation group and the control group by using a random number table method,with 60 patients in each group.After discharge,patients in the control group received routine continuing care intervention,while patients in the observation group received continuing care based on Roy's adaptation model.Before and at 1 year of intervention,the posttraumatic growth level of patients in the two groups was evaluated by using the posttraumatic growth inventory(PTGI),the adherence to antiplatelet and anticoagulant medication of patients in the two groups was evaluated with the medication adherence questionnaire(MAQ),and the quality of life of patients in the two groups was evaluated with the China questionnaire of quality of life in patients with cardiovascular diseases(CQQC).Patients in the two groups were followed up for 1 year.The major adverse cardiac events(MACE)that occurred within 1 year were recorded.Results The proportion of patients with strong adherence in the observation group was significantly higher than that in the control group(x2=9.969,P＜0.05).Before the intervention,there was no significant difference in the PTGI and CQQC scores of patients between the observation group and the control group(P＞0.05).At 1 year of intervention,the PTGI and CQQC scores of patients in both groups were significantly higher than those before intervention,and the PTGI and CQQC scores of patients in the observation group were significantly higher than those in the control group(P＜0.05).The total incidence of MACE in the control group and the observation group was 23.33％(14/60)and 8.33％(5/60),respectively.The total inci-dence of MACE in the observation group was significantly lower than that in the control group(P＜0.05).Conclusion The Roy adaptation model can significantly improve the patient's posttraumatic growth level and secondary preventive medication adherence in continuing care after STEMI intervention treatment,reducing the occurrence of MACE and improving the quality of life.

Objective:To investigate the effect of traditional Chinese medicine (TCM) lotion on incidence of postoperative infection and recurrence of refractory paronychia.Methods:Seventy-eight patients with intractable paronychia who received treatment at Hangzhou Third People's Hospital from January 2019 to November 2022 were included in this study. The patients were randomly divided into the povidone-iodine group ( n = 39) and the TCM lotion group ( n = 39) using the random number table method. Both groups underwent matrixectomy via a lateral incision and rhomboid flap excision surgery. Prior to the procedure, the povidone-iodine group received treatment with a 5% povidone-iodine solution, whereas the TCM lotion group was administered a TCM lotion containing Scutellaria barbata, Verbena, Lonicera japonica, Viola, Rheum palmatum, Atractylodes, Glauber's salt, Phellodendron, red peony root, Glycyrrhiza uralensis, and Magnolia officinalis. Both groups underwent treatment until the patients fulfilled the surgical indications and were subsequently observed for a period of 6 months post-surgery. The clinical efficacy was evaluated 1 month after the surgical intervention. A comparative analysis was conducted to assess the postoperative duration of redness and swelling, pus discharge, granulation, and pain resolution between the two groups. Additionally, the postoperative occurrence of wound-dressing adhesion, the status of wound healing, pain intensity at 1 and 3 days post-surgery, the incidence of infection at 1 week post-surgery, and the recurrence rates at 1 and 6 months post-surgery, were compared between the two groups. Results:At 1 month post-surgery, the total effective rate in the TCM lotion group was 92.31% (36/39), which was significantly higher than that in the povidone-iodine group [71.79% (28/39), χ2 = 4.26, P < 0.05]. The postoperative durations of redness and swelling, pus discharge, granulation, and pain resolution in the TCM lotion group were (5.66 ± 0.58) days, (3.64 ± 0.55) days, (8.42 ± 1.58) days, and (3.36 ± 0.32) days, respectively, which were significantly shorter than those in the povidone-iodine group [(6.73 ± 0.65) days, (4.56 ± 0.48) days, (9.77 ± 2.56) days, (3.89 ± 0.48) days, t = 7.67, 7.87, 2.80, 5.73, all P < 0.05]. The proportion of mild adhesion between the wound and dressing was significantly higher, while the proportion of severe adhesion was significantly lower, compared with the povidone-iodine group ( Z = 4.64, both P < 0.05). The durations of postoperative pain, the time to redness resolution, and wound healing time in the TCM lotion group were (4.22 ± 1.73) days, (3.02 ± 1.16) days, and (11.84 ± 2.50) days, which were significantly shorter than those in the povidone-iodine group [(8.53 ± 2.48) days, (5.20 ± 2.31) days, (13.32 ± 2.86) days, t = 8.90, 5.26, 2.43, all P < 0.001]. At 3 days post-surgery, pain scores in each group were significantly lower than the respective scores at 1 day post-surgery. At 1 and 3 days post-surgery, pain scores in the TCM lotion group were (3.30 ± 0.18) points and (2.28 ± 0.23) points, respectively, which were significantly lower than the respective scores in the povidone-iodine group [(3.61 ± 0.29) points, (2.52 ± 0.33) points, t = 5.67, 3.72, both P < 0.05]. There were no significant differences in the incidence of infection at 1 week post-surgery and the recurrence of refractory paronychia at 1 and 6 months post-surgery between the two groups (all P > 0.05). Conclusion:The combination of TCM lotion and matrixectomy through a lateral incision and rhomboid flap excision surgery for the treatment of refractory paronychia can help shorten pre-operative treatment time, minimizes postoperative wound-dressing adhesion, promote wound healing, alleviate postoperative pain, and decrease the incidence of infection and recurrence of refractory paronychia, demonstrating superior efficacy compared with treatment with a 5% povidone-iodine solution.
