Aim To investigate the mechanism by which Aiweixin oral liquid(AWX)alleviates myocar-dial ischemia-reperfusion injury in rats through the reg-ulation of mitochondrial fusion and fission.Methods Seventy-two healthy male Sprague-Dawley rats were randomly assigned to six groups(n=12)using a ran-dom number table:sham surgery group,model group,low-dose AWX(1 mL·kg-1)group,medium-dose AWX(2 mL·kg-1)group,high-dose AWX(4 mL·kg-1)group,and positive control drug trimetazidine(10 mg·kg-1)group.A myocardial ischemia-reper-fusion injury(MIRI)model was established by ligating the left anterior descending coronary artery of the rat heart,followed by 30 minutes of ischemia and 90 mi-nutes of reperfusion.In the sham surgery group,only a suture was placed without ligation.The rats in the treatment groups were pre-gavaged with AWX starting 10 days prior to the modeling procedure.Lead Ⅱ elec-trocardiograms were recorded before and after reperfu-sion in each group to observe the changes in electrocar-diographic parameters.The myocardial infarct size in each group was assessed using TTC staining.The his-topathological changes in myocardial tissue were exam-ined under a light microscope using hematoxylin and eosin(HE)staining.The serum levels of adenosine triphosphate(ATP)and cardiac troponin I(cTnI)were measured using enzyme-linked immunosorbent as-say(ELISA).Superoxide dismutase(SOD)activity and the levels of malondialdehyde(MDA)and lactate dehydrogenase(LDH)were determined using bio-chemical assay kits.The protein expression levels of dynamin-related protein 1(dynamin-relatedprotein 1,DRP1),mitochondrial fission factor(mitochondrial fis-sion factor,MFF),mitochondrial fission protein 1(mi-tochondrial fission protein 1,FIS1),mitofusin 1(mito-fusion-1,MFN1),and mitofusin 2(mitofusion-2,MFN2)were evaluated by Western blot analysis.Re-sults Compared with the sham group,the model group exhibited aggravated myocardial tissue pathological damage,an increased percentage of myocardial infarct size,decreased serum SOD activity and ATP levels,and significantly elevated levels of MDA,cTnI,and LDH activity.Additionally,the protein expression of mito-chondrial fission factors DRP1,MFF,and FIS1 was up-regulated,while the expression of fusion-related factors MFN1 and MFN2 was downregulated.Compared with the model group,Aiweixin oral liquid significantly alle-viated myocardial injury,reduced the percentage of my-ocardial infarct size,increased serum SOD activity and ATP levels,decreased MDA content and cTnI and LDH activity,downregulated the protein expression of mito-chondrial fission factors DRP1,MFF,and FIS1,and up-regulated the protein expression of fusion-related factors MFN1 and MFN2.Conclusion Aiweixin oral liquid alleviates myocardial ischemia-reperfusion injury in rats by regulating abnormal mitochondrial fusion and fis-sion.

Objective:To explore the significance of any correlation between the cost of the rehabilitation provided to stroke survivors during their hospitalization and the functional levels attained, and to analyze factors influencing that correlation.Methods:The International Classification of Functioning, Disability and Health Rehabilitation Set (ICF-RS) was used to evaluate the functioning of 304 stroke survivors on their days of hospital admission and discharge, as well as on their 10th day in hospital. The cost of their rehabilitation was computed, and demographic and clinical data were collected. A generalized estimation equation was used to analyze the changes in dysfunction with time and its risk factors. The relationship between functional levels and rehabilitation cost and its influencing factors were analyzed.Results:Length of stay, age≥60 and hemorrhagic stroke were significant risk factors for greater dysfunction among the stroke survivors. On the 10th day in hospital and the day before discharge (the 18th day), the frequency of severe dysfunction had decreased. The significant predictors of increased cost were severe or moderate dysfunction, the stage of stroke (sub-acute stage), and non-first rehabilitation.Conclusion:Functional level is a useful predictor of rehabilitation cost. It is influenced by the stage of stroke and non-first rehabilitation.

Objective:To investigate the clinical characteristics, prognosis, and the impact of different secondary prevention strategies on stroke recurrence in patients with carotid web (CaW)-associated acute anterior circulation large vessel occlusion (LVO).Methods:A retrospective analysis was conducted on 401 patients with acute anterior circulation LVO who underwent mechanical thrombectomy at 2 advanced stroke centers, Xingtai Central Hospital and Xingtai People′s Hospital, from January 2018 to June 2024. CaW was identified using digital subtraction angiography (DSA) and other imaging modalities. Based on the presence of CaW, patients were divided into CaW group and non-CaW group. Differences between the 2 groups in baseline characteristics, clinical features, and clinical outcomes were compared, and long-term follow-up was conducted for the CaW group.Results:Among the 401 patients, the CaW group consisted of 16 patients (4.0%), while the non-CaW group included 385 patients (96.0%). Compared to the non-CaW group, patients in the CaW group were younger [53 (46, 58) years vs 65 (56, 76) years, Z=-3.811, P<0.001], had a higher proportion of M1 segment middle cerebral artery occlusion [13/16 vs 54.0% (208/385), χ2=4.602, P=0.032] and a lower proportion of internal carotid artery terminus occlusion [1/16 vs 40.0% (154/385), χ2=6.024, P=0.014]; the 90-day modified Rankin Scale (mRS) score was significantly lower in the CaW group [1.00 (0, 1.75) vs 3.00 (1.00, 4.00), Z=14.210, P<0.001], and the proportion of patients with favorable functional independence (mRS score 0-2) was significantly higher [15/16 vs 45.7% (176/385), χ2=12.350, P<0.001] in the CaW group; the incidence of pneumonia in the CaW group was significantly lower [2/16 vs 42.6% (164/385), χ2=4.562, P=0.033]. Among the 16 CaW patients, 10 received antiplatelet therapy, 4 underwent carotid artery stenting (CAS), and 2 underwent carotid endarterectomy (CEA). During a median follow-up of 29 months, patients who underwent CAS and CEA had no stroke recurrence, while 2 patients who received antiplatelet therapy had stroke recurrence and subsequently underwent CAS and CEA. Conclusions:The proportion of CaW among patients with acute anterior circulation LVO was 4.0%. The patients with CaW were younger and had a higher proportion of M1 segment middle cerebral artery occlusion. Following mechanical thrombectomy, patients in the CaW group had good functional outcomes. Simple drug therapy may be insufficient to prevent stroke recurrence in CaW patients, and CAS and CEA may be effective therapeutic options.

Objective:To observe and preliminarily analyze the risk factors related to silicone oil dependence after pars plana vitrectomy (PPV) in open globe injuries (OGI) .Methods:A retrospective clinical study. This study included 211 patients with OGI who received PPV treatment from January 1, 2005 to December 31, 2016 in Eye Injury Vitrectomy Study database. Silicone oil dependence was defined as the intraocular pressure <10 mm Hg (1 mm Hg= 0.133 kPa) in silicone oil tamponade eye 6 months after PPV. The patient's age, intraocular pressure, type of injury, length of eyeball wound, as well as the presence of ciliary body injury, choroidal injury, and retinal resection and/or defect area were recorded in detail. Logistic multifactorial regression analyzed the correlation between age, eye wound length and ciliary body iinjury, choroidal injury and retinal resection and/or defect severity and silicone oil dependence.Results:211 OGI eyes underwent vitrectomy were included, the mean age of the study population was 32.93 years (range 1-73 years), and the median follow-up period was 20.06 months (range 5.85-90.58 months). Among the 211 eyes, 121 (57.3%, 121/211), 52 (24.6%, 52/211), 23 (10.9%, 23/211) and 15 (7.1%, 15/211) were rupture, perforation, intraocular foreign bodies and penetrating injury, respectively. 98 eyes (46.4%, 98/211) of silicone oil dependence in total, among them, 64 (65.3%, 64/98), 19 (19.4%, 19/98), 9 (9.2%, 9/98) and 6 (6.1%, 6/98) eyes were rupture, perforation, intraocular foreign body and penetrating injury, respectively. Correlation analysis revealed that silicone oil dependence was significantly associated with ciliary body injury [odds ratio ( OR) = 2.150, 95% confidence interval ( CI) 1.052-4.393], choroidal injury ( OR=3.233, 95% CI 1.454-7.191), and retinal injury ( OR=2.731, 95% CI 1.393-5.353). No correlation was found with age ( OR= 0.981, 95% CI 0.960-1.002) or ocular wound length ( OR=1.716, 95% CI 0.987-2.984) ( P> 0.05). Conclusion:Silicone oil dependency following PPV in OGIs are associated with ciliary body, choroidal, and retinal injuries, but no association with age or length of the ocular wound.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

This study primarily aimed to investigate the prevalence of human papillomavirus (HPV) and other common pathogens of sexually transmitted infections (STIs) in spermatozoa of infertile men and their effects on semen parameters. These pathogens included Ureaplasma urealyticum, Ureaplasma parvum, Chlamydia trachomatis, Mycoplasma genitalium , herpes simplex virus 2, Neisseria gonorrhoeae, Enterococcus faecalis, Streptococcus agalactiae, Pseudomonas aeruginosa , and Staphylococcus aureus . A total of 1951 men of infertile couples were recruited between 23 March 2023, and 17 May 2023, at the Department of Reproductive Medicine of The First People's Hospital of Yunnan Province (Kunming, China). Multiplex polymerase chain reaction and capillary electrophoresis were used for HPV genotyping. Polymerase chain reaction and electrophoresis were also used to detect the presence of other STIs. The overall prevalence of HPV infection was 12.4%. The top five prevalent HPV subtypes were types 56, 52, 43, 16, and 53 among those tested positive for HPV. Other common infections with high prevalence rates were Ureaplasma urealyticum (28.3%), Ureaplasma parvum (20.4%), and Enterococcus faecalis (9.5%). The prevalence rates of HPV coinfection with Ureaplasma urealyticum, Ureaplasma parvum, Chlamydia trachomatis, Mycoplasma genitalium , herpes simplex virus 2, Neisseria gonorrhoeae, Enterococcus faecalis, Streptococcus agalactiae , and Staphylococcus aureus were 24.8%, 25.4%, 10.6%, 6.4%, 2.4%, 7.9%, 5.9%, 0.9%, and 1.3%, respectively. The semen volume and total sperm count were greatly decreased by HPV infection alone. Coinfection with HPV and Ureaplasma urealyticum significantly reduced sperm motility and viability. Our study shows that coinfection with STIs is highly prevalent in the semen of infertile men and that coinfection with pathogens can seriously affect semen parameters, emphasizing the necessity of semen screening for STIs.

The aim of this study was to investigate the trend in testicular volume changes after orchiopexy in children with cryptorchidism. The clinical data of 854 children with cryptorchidism who underwent orchiopexy between January 2013 and December 2016 in Shenzhen Children's Hospital (Shenzhen, China) were retrospectively analyzed. The mean (standard deviation) age of the patients was 2.8 (2.5) years, and the duration of follow-up ranged from 1 year to 5 years. Ultrasonography was conducted preoperatively and postoperatively. The variables analyzed included age at the time of surgery, type of surgical procedure, laterality, preoperative testicular position, preoperative and postoperative testicular volumes, and the testicular volume ratio of them. The average testicular volumes preoperatively and at 1 year, 2 years, 3 years, and 5 years postoperatively were 0.27 ml, 0.38 ml, 0.53 ml, 0.87 ml, and 1.00 ml, respectively ( P < 0.001). The corresponding testicular volume ratios were 0.67, 0.76, 0.80, 0.83, and 0.84 ( P < 0.001). The mean volume of the undescended testes was significantly smaller than the mean normative value ( P < 0.001, lower than the 10 th percentile). The postoperative testicular volumes in children with cryptorchidism were generally lower than those in healthy boys but were still greater than the 10 th percentile and exhibited an increasing trend. The older the child is at the time of surgery, the larger the gap in volume between the affected and normal testes. Although testicular volume tends to gradually increase after orchiopexy for cryptorchidism, it could not normalizes. Earlier surgery results in affected testicular volumes closer to those of healthy boys.

Objective:To evaluate the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in patients with middle cerebral artery bifurcation aneurysms.Methods:A retrospective analysis was performed; the clinical data of 46 patients with middle cerebral artery bifurcation aneurysms accepted Neuroform Atlas stent-assisted coil embolization in First Affiliated Hospital of Zhengzhou University, Beijing Tiantan Hospital Affiliated to Capital Medical University, First Affiliated Hospital of Harbin Medical University, Zhujiang Hospital of Southern Medical University and First Affiliated Hospital of Chongqing Medical University from January 2022 to March 2024 were collected. There were 28 ruptured aneurysms (60.87%) and 18 unruptured aneurysms (39.13%). Follow-up was performed for more than 3 months; Raymond-Roy grading was used to evaluate the aneurysm embolization immediately after embolization and during follow-up; perioperative hemorrhagic or ischemic complications were recorded; modified Rankin Scale (mRS) was used to evaluate the prognosis of the patients at discharge and during follow-up (mRS score≤2: good prognosis, and mRS score>2: poor prognosis).Results:Coil embolization was successful in all 46 patients. DSA immediately after embolization showed that 41 patients (89.13%) had completely occluded aneurysms (Raymond-Roy grading I), 2 patients (4.35%) had residual aneurysm neck (Raymond-Roy grading Ⅱ) and 3 patients (6.52%) had partially occluded aneurysms (Raymond-Roy grading Ⅲ). Perioperative complications occurred in 5 patients, including 2 with postoperative cerebral infarction, 1 with hydrocephalus, 1 with postoperative pneumonia leading to respiratory failure, and 1 with stent thrombosis during embolization. Both at discharge and 3 months after embolization, 43 patients (93.48%) had good prognosis and 3 patients (6.52%) had poor prognosis. No obvious ischemic complications (such as stent restenosis) or hemorrhagic complications (such as re-rupture of the aneurysms) were found in all patients. Thirty patients (65.22%) had imaging follow-up for 6-12 months: 26 (86.67%) had Raymond-Roy grading I, 3 (10.00%) had Raymond-Roy grading II, and 1 (3.33%) had Raymond-Roy grading III.Conclusion:Neuroform Atlas stent-assisted coil embolization has good short-term efficacy and high safety in middle cerebral artery bifurcation aneurysms, but long-term follow-up observation is still needed to verify its efficacy.
