Geraniin, a polyphenol derived from the fruit peel of Nephelium lappaceum L., has been shown to possess anti-inflammatory and antioxidant properties in the cardiovascular system. The present study explored whether geraniin could protect against an isoproterenol (ISO)-induced cardiac hypertrophy model. Mice in the ISO group received an intraperitoneal injection of ISO (5 mg/kg) once daily for 9 days, and the administration group were injected with ISO after 5 days of treatment with geraniin or spironolactone. Potential therapeutic effects and related mechanisms analysed by anatomical coefficients, histopathology, blood biochemical indices, reverse transcription-PCR and immunoblotting. Geraniin decreased the cardiac pathologic remodeling and myocardial fibrosis induced by ISO, as evidenced by the modifications to anatomical coefficients, as well as the reduction in collagen I/III á1mRNA and protein expression and cross-sectional area in hypertrophic cardiac tissue. In addition, geraniin treatment reduced ISO-induced increase in the mRNA and protein expression levels of interleukin (IL)-6, IL-1β and tumor necrosis factor-α, whereas ISO-induced IL-10 showed the opposite behaviour in hypertrophic cardiac tissue.Further analysis showed that geraniin partially reversed the ISO-induced increase in malondialdehyde and nitric oxide, and the ISO-induced decrease in glutathione, superoxide dismutase and glutathione. Furthermore, it suppressed the ISO-induced cellular apoptosis of hypertrophic cardiac tissue, as evidenced by the decrease in Bcell lymphoma-2 (Bcl-2)-associated X/caspase-3/caspase-9 expression, increase in Bcl-2 expression, and decrease in TdT-mediated dUTP nick-end labeling-positive cells.These findings suggest that geraniin can attenuate ISO-induced cardiac hypertrophy by inhibiting inflammation, oxidative stress and cellular apoptosis.

Objective:To investigate the relationship between body mass index (BMI) and gestational hypertension using two-sample Mendelian randomization analysis.Methods:The summary level data for BMI and gestational hypertension were obtained from the genome-wide association study (the deadline for data inclusion was October 31, 2023). All data were analyzed by inverse variance weighting, MR-Egger regression, weighted median, simple model and weighted model methods. Cochrane Q test was used to evaluate heterogeneity, MR-Egger regression intercept test and funnel plot were used to assess horizontal pleiotropy. Results:Inverse variance weighting result under fixed effects and random effects models showed that the risk of gestational hypertension increased with the increase of BMI ( OR = 1.62 and 1.62, 95% CI 1.39 to 1.88 and 1.39 to 1.88, P<0.01). Sensitivity analysis results including MR-Egger regression, weighted median and weighted model methods showed that BMI increased the risk of gestational hypertension ( OR = 1.51, 1.56 and 1.71; 95% CI 1.01 to 2.26, 1.23 to 1.99 and 1.09 to 2.69; P<0.05 or <0.01). Although Cochrane Q test result showed evidence of heterogeneity ( P = 0.04), inverse variance weighting under a random model suggested that BMI increased the risk of gestational hypertension. Horizontal pleiotropy was not observed in the above analysis ( P = 0.73). Conclusions:Obesity may increase the risk of gestational hypertension. Pregnant women should pay attention to weight control to decrease the risk of gestational hypertension.

Objective:To evaluate the short-term outcomes of all-inside endoscopic running locked stitch technique for acute Achilles tendon ruptures.Methods:This is a retrospective case series study. Forty-eight cases with acute Achilles tendon rupture were treated with the all-inside endoscopic running locked stitch technique from April 2020 to March 2022 at Department of Orthopaedics, General Hospital of Central Theater Command. There were 44 males and 4 females, aged (34.8±7.4) years (range: 24 to 50 years). Body mass index was (21.2±2.4)kg/m 2 (range: 18 to 26 kg/m 2); There were 29 cases (60.4%) on the left side and 19 cases (39.6%) on the right side. Under endoscopic control, the proximal tendon stumps were stitched with the running locked method using a semi-automatic flexible suture passer. The threads of the high-strength suture were grasped through the paratenon sub-space and then fixed into calcaneal insertion with a knotless anchor. MRI of Achilles tendon was performed to observe the regeneration of Achilles tendon during follow-up. Surgical time and complications were assessed. Achilles tendon total rupture score (ATRS), Achilles tendon resting angle, and heel rise height were utilized to evaluate final clinical outcomes. The differences of bilateral limbs were compared using the paired sample t test. Results:The follow-up time was (24.1±3.5)months (range:18 to 32 months). Appropriate tendon regeneration was observed on MRI at 12 months after operation. The median ATRS score ( M(IQR)) was 95.0 (4.7) points. Furthermore, there was no significant difference between the injured and contralateral side in the Achilles tendon resting angle ((17.1±2.4)° vs. (17.4±2.6)°, t=1.92, P=0.062) and heel rise height ((14.2±1.7)cm vs. (14.4±1.5)cm, t=1.71, P=0.094). No nerve injury, infection, deep vein thrombosis and re-rupture was encountered. Sports activity resumed six months postoperative in 46 patients. One patient had a slight anchor cut-out, due to an addition injury, which was removed after 5 months. Conclusions:All-inside endoscopic running locked stitch technique for acute Achilles tendon ruptures shows promising results. It provides stable connection of the tendon stumps with a low risk of complications.

Objective Meta-analysis was performed to evaluate the clinical efficacy of fenestration decompression and curettage in the treatment of jaw cyst.Methods Randomized controlled trials comparing fenestration decompression and curettage in treatment of jaw cysts were retrieved from PubMed,Cochrane Library,CNKI,SinoMed,VIP and Wanfang data from built databases to June 2024.A Meta-analysis was performed using RevMan 5.4 software to compare the rate of capsule volume reduction,bone hyperplasia thickness and bone density at 3,6 and 12 months after treatment with two methods.Results A total of 14 literatures were included.At 3,6 and 12 months after operation,rate of capsule volume reduction and bone density after fenestration decompression were significantly better than that after curettage.At 6 and 12 months after operation,bone hyperplasia thickness after fenestration decompression were significantly greater than that after curettage.Conclusion Fenestration decompression is superior to curettage in the treatment of jaw cyst in terms of rate of capsule volume reduction,bone hyperplasia thickness and bone density.

Objective To evaluate the degree of brain atrophy in spinocerebellar ataxia type 3(SCA3)patients based on artificial intelligence(AI)technology,and to explore the correlation between the degree of brain atrophy and the severity of the disease.Methods The clinical and imaging data of 23 SCA3 patients(SCA3 group)and 24 healthy controls(HC)(HC group)were collected.The International Cooperative Ataxia Rating Scale(ICARS)was used to evaluate the severity of ataxia in patients with SCA3.AI technology was used to process the 3D-T1 WI MR image data of the SCA3 and HC groups to segment and measure the volume and volume percentage of brain,followed by correlation analyses between brain structural alterations and the severity of ataxia in SCA3 patients.Results There were no significant differences in gender and age between the two groups(P＞0.05).The SCA3 group had a significant reduction in the volume and volume percentage of various brain regions,such as the frontal,temporal,parietal,occipital,limbic,right cerebral white mat-ter,subcortical gray matter,cerebellum and brainstem,compared to the HC group(multiple hypothesis testing adjusted P＜0.01).In the SCA3 group,the ICARS showed positive correlation with patient age(r=0.571,P=0.004)and negative correlation with the vol-ume of the left cerebellar white matter,vermis,medulla oblongata,and the volume percentages of bilateral cerebellar white matter,vermis,pons,medulla oblongata(P＜0.05).Conclusion The significant atrophy of the supratentorial and subtentorial regions of the brain in SCA3 patients.The globus pallidus exhibits the most substantial atrophy,suggesting its potential as an imaging diagnostic marker of SC A3.
